  • The present work has as main objective the analysis of the ad hoc nomination process, from October 1988 to May 2009, for Certified Translators and Commercial Interpreter (TPICs) carried out by an autarchy of the State of Minas Gerais. This study describes the main criteria adopted by the manager of this Minas Gerais autarchy in the decision to hold a public exam for the qualification of TPICs in place of the ad hoc appointment considering the rules and principles that govern public administration, in the light of Dworkin's studies about discretion and decision based on rules and principles. This is a longitudinal, qualitative and descriptive research. The methodology is the study of simple case with technique the data collection research, followed by document analysis and content analysis. In the results, study points to the use of the principle of efficiency as criterion for appointments ad hoc due on the given routine to the procedure. Once the social approval pattern has changed, the criterion was follow the rule that obliges the holding of the contest, that is, all-or-nothing, under Ronald Dworkin's terms

  • This work, classified as descriptive, bibliographic, documentary and ex post facto, aims to investigate the performance behavior of financial institutions, measured through the most relevant indicators in the assessment of profitability, in periods of crisis (2008 and 2015) and not crisis. The sample of this research consists of 21 banking financial institutions and the time interval for the analysis is from 1995 to 2018. It was concluded that of the three classes of economic-financial indicators presented by Assaf Neto (2012), only the one referring to solvency and liquidity showed to have been impacted by the world crisis of 2008 and the economic recession in Brazil in 2015 when observing significant differences of performance in periods of crisis and non-crisis. In addition, by analyzing the descriptive statistics of this factor composed of the Loans / Deposits Index, it can be seen that there was an increase in median values in periods of crisis / recession, suggesting that the effect of these moments is not necessarily negative for financial institutions.

  • The main objective of this research was to analyze the articulation between decision processes and innovative capacities in the implementation of technological and social innovations in an electricity generating company. The questioning of the research highlights the importance of innovation in contemporary times, as well as its development linked to the United Nations Sustainable Development Goals, which are, in this research, those related to access to renewable energy and sustainable economic growth with decent work. In theoretical terms, the relationship between the concepts of technological innovation, social innovation, innovative capacities and their determinants was discussed, as well as decision processes as a crucial factor for such capacities. The methodological path was designed around a descriptive qualitative research, whose method chosen was the case study. Data collection was performed via documentary analysis, semi-structured interviews, focus group and questionnaire, treated through content analysis. This research was developed within the scope of the R&D project ANEEL 1704, in which a new modality of action was proposed based on the implementation of a hydro-solar binary and the sharing of energy credits, through shared distributed generation to promote social businesses and technical training of the community, promoting technological and social innovation. The results point to the existence of a relationship between technological and social innovation, identifying the main determinants of innovative capabilities. The determinants of technological innovation capacities converge with the factors that determine social innovation capacities, with some peculiarities. For example, when working with social innovation, communities are directly involved, requiring a knowledge of the social context and the reality that is being experienced. Furthermore, it was observed that the decision-making process emerges as a crucial determinant for innovation capacities, especially those of social innovation. Although there are not many studies relating the decision-making process to innovation, this research shows the relevance of this relationship because, even if the company has all other capabilities, it can still decide not to carry out the innovation internally and this has consequences for development innovative capabilities over time. This research contributes to the field of innovation by showing that a company can reconcile technological and social innovation, reaping benefits such as increased productivity, availability of trained people, valuing local potential, positive transformations in society and strengthening the electricity sector as promoter of social development.

  • The choice of the capital structure and dividend distribution policy of a company is considered a complex decision because it involves several factors such as risk and return that may impact on the value of the companies. From Portfolio Theory by Markowitz (1952), there were further contributions on the pricing of assets and models that explain the process of generating stock returns. The debate on capital structure and dividend policy was intensified after the works of Modigliani and Miller (1958, 1961) as it contradicted the mainstream and aimed to show that the effect of capital and dividend policy structure of a company, in a perfect market, did not influence the value and proposed that the value of the firm is determined by the investments. Since then, there has been an intensification of theoretical and empirical studies on the issues, but there is still no consensus, continuing to attract new research. The electric sector needs an intensive use of capital to finance electric generation, transmission and distribution activities to ensure supply in the country. In this context, defining the capital structure and the dividend distribution policy, based on attracting and maintaining robust investments, can be determining factors for obtaining results capable of remunerating: i) the capital invested; ii) the risks inherent to the activity and iii) guarantee quality and fair price in the provision of the public service. As a result, the objective of this dissertation was to verify the impacts of the capital structure and the dividend policy on the market value of common shares, publicly-held companies, of the electric sector traded in “Brasil - Bolsa - Balcão [B]3”. This is a quantitative survey, with a sample por 30 companies. Data were collected in the Bloomberg system and analyzed for the period 20 10 to 2019In econometric terms, it was decided to use regression with panel data. After the tests, the Data Model in a Fixed Effects Panel was adopted, which proved to be statistically significant at 5%. As dependent variable we used the Return of Common Shares and as variables explanatory: the Market-to-Book Ratio, Size, Price-Earnings Ratio, Beta, Financial Leverage (proxy for Capital Structure), Dividend Yield (proxy for Dividend Policy) and Difference Settlement Price - PLD. The results showed a negative and significant relationship between the dividend policy and the return on shares, however, the Capital Structure presented a negative relationship and without statistical significance at 5% with the returns. Also noteworthy was the statistical and positive significance between the returns with the Book-to-Market Index and Size, and the negative relationship with the PLD. The variable Price-Earnings Ratio and Beta were not statistically significant at 5%.

  • This research aimed to understand, from an ergological perspective, how the tensions between the market values and the values of the common good are evidenced in the micromanagements present in the work of the coordinating teams of the Integral Education policy of the state public network of Minas Gerais. The transformations in the world of work, provoked by the exhaustion of the Taylorist-Fordist model, which point to the necessary rescue of the importance of the human component for the achievement of organizational objectives, and the recent rise of management-oriented governments in Brazil and in the world, impact the social policies and accentuate the tensions between market values and the values of the common good for public servants in the exercise of their work activity. The consideration of this scenario from the ergological approach gives the worker and his experience the due role and also highlights the decision-making processes that occur at the tactical and operational levels and their impact on the results expected by senior management. Thus, the research was carried out with civil servants from the Minas Gerais State Department of Education (SEE) who worked in the coordinating teams for the Integral Education policy between 2017 and 2020. A qualitative research was carried out, using the study strategy of case and semi-structured individual interview techniques, discussions in work groups and Content Analysis as production techniques, collection, systematization and analysis of reports. The results obtained point to the uses of self by themselves and by others in relation to the six categories of analysis employed. It is evident, then, the approximation of the public management of the market values and the strangeness of the civil servants demanded to act in this scenario, considering the different purposes of the public administration in relation to the private initiative. In addition, the civil servants pointed to arbitrations regarding which instruments of private management to absorb for the public service, as well as micro-suggestions between remaining in the coordination of the policy and the search for alternatives to continue developing their activity. The work contributes to the widening of the debate about the transforming role of public education, and to the reflection on the impact on educational policies of the tendency to bring public administration closer to values that deviate from the search for the common good.

  • The Brazilian Emergency Medical System (SAMU), performs an important role for its healthcare system, providing emergency services to attend the population’s need for first aid services, victims transports or patients transfers between hospitals. To assure a successful service for victims in need, it is essential that ambulances may reach incident sites’ quickly. One of several factors that can affect the ambulances’ agility to reach victims refers to its locations, vehicles shall be placed in a way that enables them to cover its demands properly. Therefore, SAMU managers must be aware with the location of ambulance bases and the number of vehicles as signed to each one,inorder to afford effective coverage for its requests. To support the decision making process in this field, Operations Research (OR) offers a set of methods and tools that can indicate the ideal locations to install bases and determine the best way to allocate ambulances. Hence, this work aims to apply the Facility Location Problem in the SAMU of Belo Horizonte city, state of Minas Gerais. The objective is to contribute to the development of optimization models that divide the day into multi-periods to handle the problem of bases locations, and ambulances allocation/realocation, in order to maximize the coverage of demands within satisfactory response times. This is a case study with a quantitative and applied approach, with an exploratory objective that draws on two OR’s techniques, Simulation and Mathematical Programming. Based on literature references, two models are presented. The first formulation has a deterministic approach while the second uses a stochastic approach. In addition, a multiobjective analysis is applied to the problem, aimming to maximize the coverage while the number of bases to be installed is minimized. Lastly, a simulator is used, allowing a comparison of the proposed settings by both optimization models and also a comparison of them with the current operating framework. Results from optimization suggest that the installation of new bases and/or the deferral for ambulances to move among bases may increase the coverage level of the system about to 30% (deterministic formulation) and about to 24,6% (stochastic formulation). Through simulation it is possible to infer that the stochastic model without realocation generates the best coverage results. It is also observed that, given the current base locations, the realocation proposal suggested by the stochastic formulation is the one that provides the best results.

  • This research aimed to investigate the perceptions of workers in food and vitamin analysis laboratories, the nutrition and health department of an IFES about their working environment in order to subsidise management with people and decision-making processes in this environment. This objective was based on the discussions about risks present in research and teaching laboratory environments. It was assumed that, due to the very nature of their activities, these laboratories are immersed in physical, chemical and biological risks, among others. This is because people, equipment, reagents, solutions, agents and biological samples and waste generated in these activities coexist in this environment, which makes these places fruitful for the occurrence of several types of accidents. This research was qualified as descriptive, case study type and counted on the techniques of documentary research, systematic observation, semi-structured interview and application of the Working Context Assessment Scale for data survey. The theoretical base of this research was the Ergonomics of Activity, whose analytical dimensions "work context, "individual" and "work", understand that improving well-being at work and ensuring efficiency and productive effectiveness will only be possible if we take for analysis those fundamental dimensions that make it possible to look at the individual in his work context. The study revealed that the socioprofessional relations are very positive between workers and these aspects of work context in the laboratories have been reflected in people management and also in decision-making processes. The perceptions of the workers highlighted still, that this context assumes specific characteristics in relation to the management of people's safety and strict compliance with standards. These characteristics are seen as more specific of this work compared to other functions. The research provided also to know the commitment of these professionals in the search for ways to carry out their work highlighting the actions related to the quality of the results of this work, especially in the laboratorial analysis they made. These results comprise teaching and scientific research processes, in which precision is paramount. All the evidence gathered in the research contributes for the decision-making processes in the sector, with the necessary information for these processes. The professionals of the laboratories under study are like so many others who, with dedication, perseverance and many studies, bring to people countless benefits, such as cures of diseases, vaccines; and food fortification. They also have their daily struggles, sometimes in conditions that are not ideal, for the love to a work for themselves and for the others.

  • The profession of traffic agents emerged in 1997, from the Brazilian Traffic Code that determined the municipalization of traffic inspection, engineering and education through administrative decentralization in the provision of these services. Since then, the work of these agents has been standardized in different documents, such as the resolutions of the National Traffic Council and municipal legislation. However, such norms are not able to anticipate what is done with work in the real life space, which needs to be mobilized to carry out the activity, especially in contexts of precarious working conditions in the public service. This demands that agents mobilize knowledge, values, uses of themselves, to carry out the activity. Although some aspects of this activity have been studied under microscopic perspectives, notably in the fields of psychodynamics, activity ergonomics and psychosociology of work around phenomena such as premature aging, experiences of pleasure and suffering, absenteeism and exposure to violence. However, this study proposes to analyze in depth the most invisible aspects of the agents' activity from an ergological perspective, which “constitutes a project to better know and, above all, to better intervene on work situations, to transform them”. The objective of this dissertation was to look at the work activity of traffic agents in the municipality of Betim, mainly to understand how they use themselves, create and mobilize knowledge, values and experiences to carry out the work activity in the growing context of precarious public services. As a method, it was a qualitative, descriptive study, which used, as an instrument of data production, the technique of simple and cross-confrontation, the sample was composed of 12 agents divided into 6 pairs in 2 work shifts. As main results, it was possible to observe how the confrontation between the workers and their image at work allowed them to relive the experiences of their choices and the way to mobilize their knowledge, their values, their understanding of the context and, above all, and what it is required of your body at work. The confrontations showed that transit agents have a particular understanding of their role in articulating interests between the poles of values with and without dimension, about the enigmatic and diverse character of the activity itself, in addition to revealing how, in the face of scarcity contexts of resources and cultural problems of traffic in the municipality, workers act, making use of themselves, mobilizing what they can to meet the demand of the population and their own satisfaction with their work. The results also showed that the agents' activity emerges in the debate of norms between the different prescriptions that constrain them and the understanding of these workers about their own way of doing, in addition to pointing out contributions of the ergological approach to the decision processes on the organization of work in public services.

  • In the last decades, the process of productive restructuring has reorganized the production and management systems of labor organizations, prioritizing the institutionalization of flexible relationships in the work environment, to meet the volatile demands of neoliberalism. An important issue in this scenario that has been gaining ground in global legal instruments, as well as in academic literature, is the flexibility of working hours. Scientific research on the impacts of flexible working hours on workers' health has led to different results, which bring us evidence both of the significant gains in quality of life, as well as of elaborate forms of exploitation and precarious work. However, no empirical studies have been found that deal with the reverse, that is, the process of “deflexibilization” of the workday. Considering this gap in scientific work, the present research aims to understand the experiences of Technicaladministrative in Education (TAE's) servants of a Higher Education Institution (HEI) in the context of deflexibilization of working hours. The deflexibilization process - understood here as a return to the workday that was once made flexible - ended in 2017 at the researched HEI. As a theoretical guide, Christophe Dejours' theoretical approach to Psychodynamics of Work was used, given his advanced understanding of the centrality of work, as well as the role of work organization in promoting worker health. Methodologically, the triangulation of methods was used, in a quantitative and qualitative approach, due to the complexity of the research scenario. It was decided to apply the Inventory on Work and Illness Risks (MENDES; FERREIRA, 2007) to understand the general scenario of the institution and later a focus group was set up in order to deepen and explain the results found. For analysis of quantitative data, descriptive statistics were used, and for qualitative data, content analysis. As one of the final results, it was possible to confirm empirically the proposition that the experiences of pathogenic suffering have been established in the effective work of the TAE's of the HEI, and that the process of deflexibilization contributed to the loss of the experiences of pleasure of the servers.

  • This study has as general objective implementing the Process Maturity Management Tool Iris, which articulates the models 8 OMEGA ORCA and Balanced Scorecard (BSC), to support top management decision-making at Federal Center of Technological Education of Minas Gerais (CEFET-MG) in relation to the Institution’s strategic objectives and the search for the continuous improvement of its processes. For that reason, the nature of the methodological objectives adopted was exploratory and insider action research, under the Organization Development modality was used as the research strategy. Data was generated through bibliographical research, documentary research, executive meetings with top management representative and structured questionnaire. This structured electronic questionnaire was answered by 26 managers and facilitators designated by the Institution for Business Process Management. The results indicated that seven out of nine organizational elements assessed are in the initial stage of maturity (levels 1 to 3). The elements Commitment of Top Management and Organization and Structure, reached intermediate level 4. The overall maturity level of the Institution is 3, classified as Design, according to the framework classification. New stages for each element were traced for a timeframe of five years. The goals set intend to level all organizational elements and pillars in the intermediate stages at the end of the next strategic cycle of the Institucional Development Plan (IDP). After the gap analysis, the framework pointed to directives for action in relation to the pillars of strategy, people, processes and technology. Directives can contribute to the definition of institutional strategic objectives, that will be developed by the IDP working team. The use of the Balanced Scorecard (BSC) for the long-term strategic management of the organization's critical processes – the second part of the Iris tool – was recommended for the development of the Institutional Development Plan (IDP 2021-2025). The study validated the Iris tool as a viable alternative for other educational institutions and public administration agencies to assess their processes’ maturity levels and to monitor their performance towards continuous improvement from reliable action plans.

  • The main objective of this research is to analyze how are the decision-making processes in the management of innovation in organizations of the Domotics line, located in the technological zone of Santa Rita do Sapucaí, Minas Gerais, Brazil. To achieve the objective, the theoretical discussion built on decision-making processes and innovation, mapping concepts, types, processes and other aspects of these themes. The methodological path was designed around a qualitative research, with a descriptive objective, through the study of four organizations of the Domotics line located in Vale da Eletrônica. The content analysis was performed using the MaxQDA software with data obtained through interviews, non-participatory observation and document analysis. It was found that organizations implement radical and incremental innovations in products and processes, maintaining diversified innovation models. These organizations do not practice business model innovation, but are unanimous in the practice of open innovation. It is also concluded that the decision-making processes in the management of innovation in these organizations happen at the strategic level due to cost, risk and uncertainties. Innovation facilitators are found in internal and external variables, with emphasis on external partnerships. Another important factor in the decision-making process in innovation management is the barriers to innovation, with difficulties related to the government and its universal entities to all participating organizations. Organizations practice the rational model in the decision-making process, have stages similar to the theory and different elements according to their realities, with notoriety in the market. This research had as theoretical contribution the development and articulation of the themes decision making and innovation aligned with Domotics. As a practical contribution, we can mention the identification of the challenges of organizations in decision-making in the management of innovation and barriers with the government and its institutions.

  • The process of convergence to international accounting standards applied to the public sector provided the emergence of Brazilian accounting standards directed to the public sphere, one of which is the object of this study, NBC T 16.11. This standard deals with the implementation and use of the Public Sector Cost Information System (SICSP) and highlights the need for cost information to promote transparency, support the decision-making process and perform an adequate accountability. Given the importance of NBC T 16.11, the present research had as general objective to analyze the perception of public controllers and accountants about the implementation and use of SICSP in the municipal halls of Minas Gerais. In order to do so, the following specific objectives were established: 1) to characterize the public controllers and accountants; 2) to identify the profile of the municipalities regarding the implementation and use of the SICSP; 3) to investigate the perception of controllers and public accountants regarding the usefulness of SICSP in the decision-making process; 4) to analyze whether there are relationships between the size of the municipality and the degree of difficulty in implementing/using the SICSP considering material and human resources; and the size of the municipality and the degree of usefulness of the SICSP in the decision-making process. To achieve the objectives of this research, a questionnaire was sent to each of the 853 municipalities in Minas Gerais, and 106 questionnaires were answered. The research methodology used was based on a quantitative approach with the use of descriptive statistics, the t-Student Test and pearson's correlation for data treatment. The results showed that no municipality has fully implemented the SICSP yet. The descriptive analysis showed that the degree of difficulty in implementing/using the SICSP regarding the number and qualification of the staff was significant. Most public controllers and accountants realize the importance of SICSP utility in the decision-making process, recognizing it as very useful or useful. This demonstrates that there is an awareness that the SICSP is relevant in the decision-making process by professionals, which may favor the implementation in the future. It was verified the existence of relationship between the size of the municipality and the degree of usefulness of cost information as an instrument of decision-making for economic choices. In other words, larger municipalities understand that the SICSP is very useful in this process and smaller municipalities tend to recognize a lower degree of utility. It was found that the municipalities are not structured to comply with what NBC T 16.11 determines and that there are no penalties for non-compliance. As future research, it is suggested to study other variables (such as indicators of transparency and effectiveness of municipal management) and their relationship with the SICSP. In addition, it is recommended to conduct a study through interviews to verify if there is resistance of people; discontinuity due to political succession through electoral processes and barriers related to the turnover of controllers and public accountants who are often not effective civil servants.

  • Post-graduate programs in Brazilian higher education organizations have grown considerably in recent years. With the quantitative increase of these programs, there is also a concern with the quality of the courses and the way of managing them. In the context of public organizations, in which society's contribution supports resources, it is even more necessary to evaluate efficiency so that the results obtained are according to the resources employed. With a view to this evaluation, CAPES measures educational organizations' efficiency through a scoring system, generating scores that can be compared among programs in the same area at different institutions. However, even though Capes' evaluation, it is impossible to compare post-graduate programs in different areas, making difficult internal management of post-graduate programs in the same educational organization. This study aims to verify the effectiveness of joining the data envelopment analysis technique (DEA) and networks as tools to compare post-graduate programs' efficiency in different areas, contributing to post-graduate managers to make decisions within the educational organization to which they belong. The research is with a mixed approach from a functionalist perspective. A cross-section of the years 2013 to 2018 was carried out. The investigation employed descriptive analyzes, word cloud, sociograms, structural tests of network theory (small-world, scale-free, hemophilia), and data envelopment analysis as tools to support the decision. It was found that CEFET-MG programs have characteristics of the small-world, and the presence of hemophilia among the programs was identified. It was possible to measure the efficiency of graduate programs through the combination of DEA techniques and networks. In both applications, the benchmark program was maintained after applying network indicators. Superefficiency models were used to improve the distinction of the six chosen programs, with the Technological Education and Administration programs being the ones that were most efficient within CEFET-MG, according to the chosen variables.

  • The objective of this research is to analyze how the relationship between decision-making processes and the adoption of managerial innovations occurs in a Brazilian luxury hotel. The investigation was based on the concepts and theoretical perspectives raised on the following themes: innovation, managerial innovation, innovation in hospitality, decision-making process and decision-making process in innovations, seeking an articulation between these themes, respecting the specificities. The methodological path was designed based on a qualitative approach, with a descriptive objective, using the single case study method. We investigated a resort located on the coast of the state of Bahia, Brazil, in view of the relevance and recognition of this hotel on the national and international scene, in addition to the accessibility of the researcher to the organization. For data collection, documentary analysis and eight semi-structured interviews were conducted with the main hotel managers and decision makers, in a perspective of data triangulation. The relationship between managerial innovation and the decision-making process was the basis for the proposed analysis model. In this model, the innovation adoption process was analyzed, identifying its stages and the influencing factors that impact the adoption or rejection decisions. In this way, it is concluded that the innovation adoption process is strongly influenced by internal and / or external agents that aim to seek legitimacy and reputation. It was also possible to observe the influence of the COVID-19 pandemic crisis on the managerial innovation process in the hotel, being a driving factor to accelerate the implementation of such innovations as a possible solution to the crisis experienced by the hotel. Complementing the model, it was identified as a possible barrier for managerial innovations to emerge from the tactical-operational level the training and training of people in terms of management and problem solving, in addition to communication between managers and staff, centralization of power and team autonomy operational. With the results and discussions of this research it was possible to obtain a greater understanding of decision making for the adoption of innovation in the context of luxury hotels, thus contributing to the state of the art of scientific literature and to generate a positive impact on services and organizational processes.

  • The estimation of volatility has become a topic of great relevance for both academics and professionals in the financial market. The volatility of an asset or index refers to its fluctuations over time, and its correct forecast is essentials in the financial decision-making process since there is a trade-off between risk and return, where investors want to maximize their returns at the lowest possible risk. Therefore, this work aims to estimate the volatility behavior of the daily return of the major stock market indices in the American continent, between 2007 and 2019, in order to determine and measure the risk of the stock market in the continent. To analyze the volatility of the data, the GARCH model was used. As a result, it can be stated that the volatility structures of the eight financial series examined were adequately estimated using the GARCH model. This allowed an analysis of their behavior, with clear similarities in certain periods of time, with high variability, especially in 2008 / 2009 and 2011/2012. Regarding the persistence of volatility, it was found that countries have a coefficient of persistence of volatility close to 1, indicating that shocks in volatility tend to prolong fluctuations in the return of the indexes. Bearing in mind that stock market decisions involve risk management in the purchase and sale of assets, where the risks are related to price volatility, consistent estimation becomes an important instrument in the decision-making of market players.

  • This research aims to understand the role of women's work in drug trafficking. With the purpose of construe lore from the dialogue between social and subjective knowledge as well as understanding the relationships between work and subjectivity, psychosociology was used as a theoretical contribution and the trajectory of working life as a methodological resource. The interviews were conducted with two women indicated by the “Grupo de Amigos e Familiares de Pessoas em Privação de Liberdade” [name of the non-profit organization that aims to mobilize and organize friends and family of people deprived of liberty in order to guarantee their rights]. Considering that the commercialization of illicit psychotropic substances occurs as a continuous activity and that involves quality control, price regulation, charge and payment, salary, labor relations, hierarchical network and market conquest – resembling a formal retail trade, it is conceived that the ex-drug dealers interviewed were responsible for managing a complex distribution chain, acting as decision makers in search of opportunities to maximize profits and reduce risks – since both occupied a hierarchical position that went beyond the operational in that organization. Therefore, this work seeks to understand management and decision-making processes in an illicit organization as well as raising questions about the conditions and processes of meaning of female labor in drug trafficking. Through the reports it was possible to show the agility and adaptability of the management of this activity, factors that are of paramount importance to the functioning of an illicit organization because there are ever new methods to combat their activities. Furthermore, considering that drug trafficking operates as a neoliberal market, the study showed how autonomy in decision-making is no longer a tool for the emancipation of the subject but an instrument for deterioration of labor. Lastly, the reports showed that women submit themselves more intensely to factors that put them vulnerable to mental illness in order to obtain validation of the environment and self-worth through the value of their work.

  • The professionalization of senior public administration has been treated as one of the main aspects of improving public management, placing the public leader as a prominent figure with the skills required for his performance. The Transforma Minas program implemented in 2019 in the Government of Minas Gerais has been seeking through the application of selection processes based on merit and skills to professionalize its leaders. As it is a recently implemented initiative, the general objective of this work was to reflect on the challenges and perspectives of the professionalization of senior public administration in the State of Minas Gerais considering the decision-making processes of the Transforma Minas Program and the perceptions of the actors involved. The study was based on a theoretical framework that contextualizes the theme of professionalization of public officials, especially in the Brazilian context and in Minas Gerais, management by competencies, decision-making processes, and professionalization models of senior public administration in other countries that served as inspiration for the Transforma Minas Program. The research had a qualitative-descriptive character and is based on documentary research, participant observation and ten semi-structured interviews with people directly involved in the Transforma Minas Program, including: managers, consultants, employees and participating candidates. Through the analysis of the data, it was observed that the Transforma Minas Program presents an innovative perspective in the professionalization of public officials in Minas Gerais by seeking a process for choosing leaders no longer based only on political criteria, but taking into account merit and competence. In relation to other professionalization initiatives already carried out by the State of Minas Gerais, the Transforma Minas Program differs by seeking a cultural change in the selection of leaders in the State in a broad way, and not only focused on specific functions or projects such as occupational certification and the public entrepreneur. In addition, it presented a more assertive competency mapping by focusing on the specific managerial competencies of the vacancy offered. However, some challenges are present for the institutionalization of the Transform Minas Program in the State of Minas Gerais, and consequently in the professionalization of public officials, such as: the need for legal guarantees that guarantee the mandatory application of the program for the selection of leaders in the State, and the need to legitimize the program in front of the internal and external public to the Government.

  • The Schools of Apprentices and Craftsmen have been a manifestation of public policy since the first decade of the last century. The State was looking for an application for Education that would train young people for work. The transformation of these schools into the Federal Professional Education Network did not erase their vocation to prepare for the world of work, through the culture of innovation and entrepreneurship, combined with the triad Teaching, Research and Extension. In order to promote the fulfillment of the Network's objectives and purposes, stipulated in its own Law, the Ministry of Education's Secretariat for Professional Education implemented a series of actions. This dissertation seeks to verify whether the innovation actions promoted by SETEC were effective in inducing the Innovation Poles of the Federal Professional Education Network. Based on a theoretical framework that seeks to relate decision-making processes and innovation, it was developed based on a qualitative methodological approach, via documentary research, involving strategic actions carried out from 2013 to 2020 for the 42 institutions that make up this group. At the end of the research, we will verify the historical relationship between the actions originating from the Ministry of Education and the accreditation of the Innovation Poles. Thus, we will be able to analyze the Decision-Making Process under two different biases: Public Policies for Direct Administration and Innovation Management for the respective federal schools.

  • The gastronomic market is on the rise in Brazil and is one of the initiatives that currently foster this market today is the gastronomic festivals. The event “Comida di Buteco”, which was born in Belo Horizonte 21 years ago, and takes place in 21 other cities in Brazil, is one of these initiatives, which developing activities within the scope of Creative Economy, brings together the work of several actors to offer a cultural circuit tasting and evaluating the city's butecos, with an emphasis on creativity valuing root food and small family businesses, with an impact on tourism, income generation and jobs in the city. Observing the protagonism and longevity of the event “Comida di Buteco” in the gastronomic and cultural market of the city, we sought to understand: “The development of the gastronomic market and legitimation process through a case study of the event“ Comida di Buteco”. For the research it was used the lens of Institutional Theory and its central concept of Legitimacy and considered the field of research of culture and consumption, which perceives the markets as complex social systems, and constituted by actors and institutions that interact with each other. With this objective in mind, a descriptive qualitative research was developed. The data were collected through the use of in-depth interviews with entrepreneurs and organizers and participant observation at the event. The qualitative analysis of the results showed that organizing entrepreneurs and entrepreneurs who own the boutiques interacted and adopted practices that legitimized the Comida di Buteco event, contributing to the development of the Belo Horizonte gastronomic market. The identified practices that contributed to its legitimation process covered three axes of centrality: re-signification of butecos as a space for socialization and tasting; the spontaneous media discourse and the creative reinterpretation of the kitchen from scratch. This research contributed to the understanding how the process of developing markets can be influenced by the association and practices of institutional entrepreneurs that affect consumer behavior and socio-cultural structures and providing elements and conceptual tools for decisionmaking by public and private mangers.

  • This dissertation is an analysis of the perception of civil employees about the challenges of decision-making processes encountered in the implementation of a Development School. To support this qualitative descriptive case study, a theoretical framework was built that sought to consolidate the following topics: public administration, people management, decision-making processes and schools of government. The research took place through documentary research and six semi-structured interviews, conducted with employees of the Federal Center for Technological Education of Minas Gerais, directly linked to the Coordination of People Development, current position of the School of Development of Servers and who helped in its implementation. The content analysis proposed by Bardin (2011) was the methodology used to asses the data collected, by which it aimed to describe and analyze the guidelines for training the Federal Government, the current training policy of the institution and the perception of the employees involved in the implementation, on the School of Development of Servers, of the federal autarchy in question. In this way, a very positive view of it was identified, which is considered motivating and valuing. The main challenges and difficulties encountered in the implementation were in relation to people, infrastructure, the pandemic of the corona virus, the time for the approval of the ordinance for its regulation and the legislation. It is not always possible to act on difficulties, but these can become opportunities.

  • This study proposes to understand on the activity of Justice Officials at Minas Gerais state, in the context of Psychodynamic of Work, evaluating their experiences of pleasure and suffering and their impacts on decision-making processes. It emphasizes that the work carried out by the Officials is characterized by a context with a complex nature of situations and emotions that they have to deal with daily, with no support from the district administration or the TJMG. Theoretical support for this study is: The Psychodynamics Theory of Work, based on the studies of Dejours (1994) and Mendes (2007), which assesses man's resistance to the reality of symbolic, social, political and economic domination present in work environments; and Bounded Rationality Theory, which study the limited nature of the human in face of decision-making processes. This work, along its development, seeks to guide the following research question: How are the experiences of pleasure and suffering by Justice Official in judicial district in Minas Gerais, and how this influence their decision-making? The search for these answers was guided by qualitative and quantitative studies, through the application of ITRA and socio-demographic surveys, in addition to individual interviews with some employees, with the purpose of clarifying and qualifying the quantitative analyzes. As a result, a negative evaluation was observed regarding dimensions studied, showing an illness process on employees, and which has influenced decision making and consequently the quality of the Judiciary service. Results obtained from the sociodemographic survey, initially served to contextualize the study, and later were treated together with results obtained from all ITRA scales. Complementing these analyses, categories and subcategories were defined, based on the major groups of ITRA, as well as sense cores. Analyzes of each factor of ITRA scales were exemplified with excerpts from the testimonies obtained through individual interviews, supporting quantitative results. The study showed a negative assessment regarding the various dimensions investigated, with all ITRA scales rated as critical or serious, showing a process of illness among professionals that has influenced decision-making and, consequently, the provision of the service in the Judiciary. Given this scenario, it is recommended a serious reflection by district administration or even the TJMG, in order to develop mechanisms to improve the health and quality of life of Justice Officials.

  • This research aims to propose acquisition and stock management policies through material classifications using the ABC/XYZ matrix in a hospital network. Some models were also tested to optimize the delivery of such items to the network units, from the central warehouse. It is an applied study developed in the Fundação Hospitalar do Estado de Minas Gerais (FHEMIG), the largest network of public hospitals in Latin America, and considered medical-hospital materials. The research, based on these two analyzes, constructed the matrix ABC/XYZ, obtaining of the items, which allowed to suggest replacement policies for the foundation, and consequently, establish security stocks, order point and lots of purchases, considering the resources maintenance of health care activities and the current rules of acquisition, imposed on public agencies and entities, such as the price registration system. It is concluded that to observe exclusively the financial value (ABC Curve) is not the most appropriate, since there are expensive items that are used less regularly, while some materials are relatively cheaper and have regular demand, which shows that other criteria should be analyzed to classify the inventory. Such classification is relevant given the variability of the items and to allow a management more appropriate to the use and rotation of the inputs. As for the distribution of the materials, after testing some scenarios, it is demonstrated that the adoption of vehicles with greater capacity can optimize the deliveries, reducing the costs of the contract.

  • This work aimed to investigate how the interactions between the different agents that operate in the tourist activity of Pirapora / MG affect the maturity of this productive cluster and contribute to the local development through the decision to collaborate. Tourism is an activity that seeks to meet the demand of people who seek happiness, rest and leisure. In Pirapora / MG, the formation of a Local Productive Arrangement (APL) seems to be the simplest way to create an organized offer aimed at a complete tourism product, previously designed for a basic market and, consequently, increase employment and income for its population. The research approach was qualitative descriptive and analytical, through participatory research, documentary and field research as instruments of data collection. In relation to the unit of analysis it has tourist characteristics, since the Ministry of Tourism of Brazil in its most recent classification considered it integral of the new map of the Brazilian tourism. The results showed that: a) the city has potential tourism products that are not yet formatted for supply; b) entities related to tourism participate and are involved in part with planning and acting in regional tourism; c) the interaction between them affects the development of tourism, however, as it has been conducted, it is not enough to leverage it because it needs more organization and carrying out joint activities within a short, medium and long term planning; d) the city has relevant deficiencies in the sector such as low community involvement and lack of preparedness of the population to receive the tourist; and e) the environmental problems related to the volume of water and fish have directly affected the natural attractions of the region and has served as a justification by the population for the lack of use of tourism potential. Thus, in the tourist cluster of Pirapora / MG, the interactions resulting from the decision to cooperate are directly related to their development and maturity and can lead to an articulated process capable of developing agglomeration in the short term.

  • The objective of this dissertation was to understand, from the ergological perspective, what the life history of an entrepreneur has to reveal about the entrepreneurship. The field of entrepreneurship studies has been fragmented since the Middle Ages to the present day. A historical landmark for this phenomenon was the 1970s, when political, economic, social and technological changes have made entrepreneurship gain notoriety. This encouraged some authors to seek the consolidation of the field as a scientific community, in an attempt to build a conceptual framework and minimize the fragmentation of the field. At the same time, entrepreneurship, which had previously received the attention of economics and psychology, became the object of management studies. In this sense, it was possible to reflect on the alignment of administrative theories with the interests of capital, from the classical school to the flexible production model. Currently, the debate is around the idea of entrepreneurship, self management. This historical recovery gives indications that entrepreneurship is more a depository ideology of neoliberal rationality, which tries to hide the conflicts between capital and labor. This can be confirmed by its heyday at a time of globalization and increased competition, which resulted in mass layoffs in companies that failed to keep up with the new competitive landscape. Thus, stimulating discourses of entrepreneurship emerged as a way to achieve success, when in fact it attempts to camouflage the unemployment crisis. These discourses are based on councils, imperatives and norms of conduct that function as a system of domination and make people assume a mode of behavior compatible with the capitalist system, valuing freedom, individuality and competition. In this, responsibility for career, well-being and life in general passes to the subject. Adopting the ergology magnifying glass to see entrepreneurship as an ideology, we see that in this, the poles of the tripolar system (political, market and activity) lose balance, since both the state and the individual are guided by market values. In this dissertation it was tried to throw light on the activity of the entrepreneur and for this was adopted the method History of life as a methodological path. Tux's Life Story and his trajectory with entrepreneurship show that his narratives are influenced by the ideology of entrepreneurship. However, in telling his story, emerged the conflicts, debates of norms, self-uses for themselves and for others, contradictions between mercantile values and values of the common good, which affects their decision-making processes. It has been demonstrated how the Life Story can be used as an ergological device in what concerns to summon the worker to produce knowledge about their activity and as a posture of refusal to any mutilating simplification of the work. Moreover, Tux's Life Story also represents the stories of many other Brazilian entrepreneurs what fight to keep their business up and running even in the face of unfavorable scenario.

  • The purpose of this study was to "understand the influence of the sports career on the performance of the managerial function from the perception of former athletes." The relevance of this study is to insert a discussion still little explored in the Brazilian literature, analyzing the athlete's career transition and the peculiarities of the profession. To make the analysis proposed in this study feasible, it was necessary to understand career, career transition and managerial role. In order to reach the goal, 6 former athletes were interviewed who occupied the position of manager during the period in which the research was carried out. Only those for whom the sports career was also a professional career were selected. Based on the theoretical reference, the professionals who performed some sequential functions directed to the organization (planning, implementation, operation and evaluation) and directed to the participants (stimulation, coordination and control) were considered as managers. By conducting qualitative and descriptive research, the interviews were done semi-structured and were treated through the content analysis proposed by Bardin (1977). The analysis of the interviews was divided into 3 categories - sports career, manager career and career relationship - and 8 codes. It was felt that the burden of competitions and training, the development of teamwork, leadership, knowledge of oneself limits were decisive for the construction of the current career and influence the understanding of what is the managerial function. It is understood that the greatest contribution of this study resides in the understanding that, after the transition of career, the ex-athlete who assumes a managerial function uses resources of the previous career that allow to overcome the challenges of the management. In addition, it was possible to identify that the experience in the sport is a differential for the managers that act directly or indirectly in this area.

  • Besides being closely linked to consumption, fashion is responsible for moving the textile and clothing industry, thus representing an important economic activity. Fashion is characterized by the new, by change and ephemerality, which makes it inseparable from innovation. Therefore, one of the greatest challenges for the managers of this branch is the differentiation of products, making it necessary to make strategic decisions oriented to the market. In this context, this research aimed to investigate how the decision-making of the managers of the women's fashion industry of Belo Horizonte in the selection of innovation alternatives occurs. The research was based on theories related to innovation, innovation in the fashion industry, decision-making in organizations, decision-making in the selection of innovative ideas and institutional mimicry. The focus of the research is on the first sub-process of innovation – known as the Front End, or the front line – because it is there that the identification and selection of innovation opportunities occurs. This is a critical step, since it is decisive for the final result of the innovation. The study conducted has a qualitative and descriptive approach. We investigated the case of the fashion industry of Belo Horizonte, considering that the city stands out as a national reference in fashion production. For the collection of data, seven semi-structured interviews were conducted with company managers within the competitive context of the fashion industry. As a data collection instrument, a semi-structured script containing pertinent questions about the practical application of the concepts discussed was used. The data were analyzed through content analysis with the help of QDA Miner software. The interviews were transcribed in full and loaded into the program, beginning the process of reading and categorizing the excerpts. The material was divided into categories and subcategories of analysis, defined from the theoretical reference and the verbalizations contained in the interviews, respectively. Aiming to enrich the data analysis, the "cloud of words" technique was used, through which the most recurrent words were identified in each interviewee's speech. With the results and discussions of this research it was possible to obtain a greater understanding of decision making in the context of fashion, thus contributing to the state of the art of scientific literature and to the improvement of organizational processes in this sector. During the construction of the theoretical basis, some assumptions were raised that guided the investigation as they were confronted with the results obtained in the field research. In this way, it was concluded that innovation is considered fundamental in the fashion industry, since it is the main strategy of competitiveness used by the managers to obtain differentiation in the design of the products. The fashion in Belo Horizonte is linked to social, economic and cultural aspects and companies attribute a symbolic value to the brand to become unique in the market. Often incremental, the innovation process in the fashion industry occurs collectively and in a more informal way, following a procedural model of decision making. The selection of ideas for the development of new collections occurs through defined criteria and is usually carried out by the brand owner with the support of his team. To make decisions, managers use market research and trends, but also rely on their intuitions, skills, and experiences. In addition to the innovative strategy, it is also common to use the imitative strategy in the fashion industry as a way to reduce risks and uncertainties. This way, the manager chooses the one that best matches the brand proposal and the profile of its target audience.

  • The relationship between stock liquidity and its return is a theme widely explored in the literature since the seminal work of Amihud and Mendelson (1986). Among the studies developed with this theme, we highlight the divergence of results among the works developed in the context of emerging markets. Jun, Marathe and Shawky (2003) and Correia, Amaral and Bressan (2008) are examples of authors who find a positive relationship between liquidity and returns, while Machado and Medeiros (2011) and Amihud et al. (2015) find a negative association between these variables in the context of emerging markets. Thus, this dissertation had as general objective to verify if the stock liquidity is a systematic risk factor priced in the capital markets of the emerging countries of Latin America. The initial sample of the study consisted of all stocks traded between June 1, 1999 and June 30, 2017 in the markets of the Latin American countries that were part of the Emerging Markets Index of Morgan Stanley Capital International in August 2018. To measure liquidity were considered two alternative proxies, namely: the Adjusted Illiquidity of Kang and Zhang (2014) and the standardized turnover index proposed by Liu (2006). After calculating these proxies, we tested the inclusion of a liquidity factor for each measure of liquidity in the three-, four-, and five-factor models. By using the Gibbons, Ross and Shanken (1989) test to evaluate the model results, it was observed that, in general, the models that had a liquidity factor presented a better predictive power, and the models with the constructed factor from the standardized turnover presented a greater power of explanation in comparison to the models with the addition of a factor for the liquidity based on adjusted iliquidity. The results of these models were robust in relation to the January effect and, when the sample was considered segmented in two equal periods, it was evidenced that liquidity became a more significant factor in the second half of the time window. When estimating the cross-section regressions, or models of the second step, the results pointed out that no model was able to explain the average return excess of the LHS portfolios. In addition, the highest coefficient of determination obtained for these models was related to the five-factor model with the addition of the factor constructed from the Adjusted Illiquidity.

  • In the mid-1980s, several studies provided evidence of abnormal behavior in the return of financial assets, indicating that there were risk premiums associated with different factors in the market. Such anomalies generated results that were contrary to the basic assumptions of the Capital Asset Pricing Model (CAPM) and were not explained by the model. The relevance of these factors led different models of asset pricing to emerge in the literature, seeking to improve the explanatory power of returns. This discussion became even more intense from the seminal studies of Fama and French (1993) and Carhart (1997), which presented new factorial models based on fundamentalist indicators, which incorporated variables based on the most debated anomalies in the financial literature. Considering these discussions, this dissertation proposed to verify, through empirical tests, which of the three factors of Fama and French (1993), the four factors of Carhart (1997) and the five factors of Fama and French ( 2015), presents better performance in explaining the size, book-to-market, momentum, profitability and investment in the Brazilian stock market. This study aims to add new contributions on the pricing of assets and on models that explain the process that generates stock returns, helping to make financial decisions in situations of risk. In order to test the models, we used a predictive test methodology, which applies two-step regressions – time-series and cross-section, developed by Fama and MacBeth (1973). In the models tested, the market, size, book-to-market, momentum, profitability and investment factors were used as independent variables; and the dependent variables were the excess return of the portfolios in relation to the risk-free interest rate. The results observed for the first step regressions and for the Gibbons, Ross and Shanken (1989) test showed that the five-factor model of Fama and French (2015) presented better performance in explaining the average returns compared to other models. The model that presented the worst performance for this stage was the three-factor of Fama and French (1993). When cross-section regressions were estimated, it was possible to verify that, although the five-factor model presented greater predictive power, none of the models was able to explain the variations of the returns of the formed portfolios.

  • The project manager (PM) is the figure within the organization that dialogues between the higher hierarchical levels, exerting influence in the decision-making process. It is therefore crucial to understand how these professionals make decisions and whether there is a decision-making style they are most inclined to. The study was based on the Talent Triangle (TT), developed by Project Management Institute (PMI), which defines three competencies dimensions (technical knowledge, leadership and strategic and business management) required to respond to the complexities of the projects and the market. These competencies have a close relationship with decision-making. Thus, this study aims to investigate the relationship between the decision-making style of engineering and IT managers and their preferences regarding the dimensions of the PMI Talent Triangle. To achieve the goal of the research, it was adopted the Dual Process Theory in its version modified by Regret Theory, here called TPD-m, which assumes that each individual can have a more prominent decision-making style among three possibilities: analytical, intuitive and emotional. Seeking for research resources that could dialogue with the TPD-m theory, two tools with psychology bases were adopted: 1) the DMI (Decision Making Inventory) psychometric test that aimed to investigate PM decision styles and 2) Q-Methodology, which aimed, among other things, to capture subjective aspects by suggesting to the participants to establish the most priority items of the TT dimensions The results confirm the preponderance of the analytical style among the PMs investigated and also point to a more pronounced inclination to the strategic vertex of the TT. This discussion allowed to emphasize a subject sometimes relegated to the background, which is the decision-making as a cognitive process and to deepen the studies of competence in project management, establishing a bridge between market concepts and studies in the academic environment.

  • This dissertation proposes to investigate the decision making of public sector managers regarding institutional participation and the deliberation of debates in virtual environments. Participation and deliberation have been the subject of study since the 1960s. In Brazil, struggles in the social field culminated in the recognition of various citizens rights in the Federal Constitution promulgated in 1988. This same document institutionalized social participation by calling the population to take decision-making in the public sector through thematic deliberative councils. Other participatory programs were built from the 1980s, with emphasis on the Participatory Budget. With the increase of information technology, since the beginning of the 21st century, instruments for participation in the virtual environment were created, including the UFLA More Innovative Solutions Program, from the Federal University of Lavras. Thus, the objective of this work was to analyze which participation typologies were verified in the UFLA + Innovative Solutions Program, as an instance of institutional participation and online public deliberation. The study to be conducted has a qualitative bias, following an interpretative approach. For data collection, documentary sources were used about the program's website and the interaction platform, about the announcement that regulated the participation in the program and about the users; posts about the platform. Data were analyzed through content analysis with the aid of Atlas.ti software, version 7.5.16. The analysis categories for coding were based on Dahlberg (2004) and Dahlberg (2011). They are divided into Liberal Consumer, Deliberative, Anti-Public and Autonomous Marxist. The constitution of the platform, the convening instrument with the program rules were analyzed and a very high frequency was observed in participations classified as Liberal Consumer, which shows that there was more interest in the award than in the changes that the program could propose in the program. University. With the results and discussions of this research, it is intended to contribute to a better understanding of the decision making processes in public organizations.

  • The purpose of this dissertation is to understand, through an ergological point of view, the certification process of school principals of Minas Gerais state. Beginning in 2006, the occupational certification process of state school principals in Minas Gerais aims to identify whether the professional has the necessary skills to assume a specific position/function and meets the technical requirements, with their respective responsibilities and activities. The choice for an ergological approach in the present research was made mainly to give centrality to voice of the school principals so that they can expose their vision about the certification process. Considered a démarche, a path to be followed, the ergology proposes to better understand and intervene in work situations in order to transform them, bringing the worker to the center of attention, focusing on built knowledge and seeking to understand the debates they experienced in the execution of their work. In view of the objective of the work, semi-structured interviews were conducted with school principals of Belo Horizonte’s metropolitan area, in addition to having as object of study occupational certification as its object of study this research addresses the organization of Brazilian education, the history and the processes of choosing the figure of the school principals, as well as the literature that aims to identify the competencies required for the Brazilian school administration. It can be concluded that the implementation of the occupational certification studied was carried out in tow of a national movement that aimed to improve the results of education in Brazil, which instituted a systematic of metrics and controls to evaluate the evolution of teaching quality in Brazil. parents. This movement is a clear example of the injection of market values, of individual values that can be quantified on the political pole, of unquantifiable values, of the common good. Having verified the relationship between the competences / qualities of the school manager to this improvement, occupational certification has become the quality seal of the professional who holds this position, which validates the efforts of the state government to improve the quality of education. However, through the interview of the school principals the certification cannot encompass the reality of their work or prepare the candidates for position.

  • The increase in high frequency trading and expansion of tick-by-tick databases have led to the increase in market microstructure research, especially those dealing with market liquidity and informational asymmetry present in transactions. Consequently, several studies, instigated by the possible influence that informational asymmetry has on market liquidity, sought to identify the occurrence of informational asymmetry in markets. These studies eventually found that the Volume-Synchronized Probability of Informed Trading (VPIN), model proposed by Easley, Prado and O'Hara (2012), directly measures the degree of order flow toxicity, i.e., the likelihood of informational asymmetry in trading. Therefore, the objective of this research was to analyze the impact of the order flow toxicity (VPIN) of future contracts of future DI and commercial dollar of B3 on the bidask-spread of these assets. Therefore, were used intraday data from January to December of 2018, and an SLR model. Results show that, regarding the illiquidity of contracts, measured through the bid-ask-spread proxy, DI Futures contracts were more liquid than commercial dollar contracts, with averages of 1.4774 and 3.5731, respectively. Regarding toxicity, future DI contracts had 12,518 buckets, averaging 0.0073 and when it comes to commercial dollar contracts, 12475 buckets, averaging 0.0006. Regarding the estimated models, the results for future DI pointed to a direct relationship between toxicity and illiquidity, corroborating the research hypothesis. The commercial dollar model, on the other hand, indicated an inverse relationship between toxicity and illiquidity, contrary to the research hypothesis.

  • Currently, the Brazilian electricity matrix is predominantly hydroelectric, with a share of over 63%. This implies huge climate dependence, as well as thermal power plant activation at times of rationing, increasing the cost of the tariff. On the other hand, it is observed that the source of photovoltaic solar distributed power generation, which Brazil has abundant resources, such as territorial space and good level of irradiation, still has incipient participation in the Brazilian electric matrix, around 0.14%, according to the National Energy Balance (2018). Therefore, this research sought to structure a financial viability model, aiming to support decision making in investments of solar photovoltaic distributed power generation, as well to provide an analysis of the impacts for the energy distributor and for the State (Federal and State). For this purpose, this research was developed through a quantitative investigation, which included a sample of 1,973,766 UC's consumer units, in 773 municipalities of Minas Gerais, in concession area of Cemig Distribuição S.A., from 151kWh to 500kWh consumption range. The sample period used was 2018. The feasibility analysis was performed considering three different perspectives: consumer, energy distributor and the State. The analysis was supported by the following financial indicators: Net Present Value (NPV), Internal Rate of Return (IRR) and Payback, along with the Monte Carlos simulation for the following variables: equipment and installation price, inflation and minimum attractiveness rate. In addition, some scenarios were performed considering variations in the kw price. In conclusion, from the consumer perspective, for the 25-year time series, which was the one adopted for cash flow, all UCs were financially viable. The lowest PayBack and the highest IRR, per mesoregion, were respectively 6.36 years and 22.19%. When applying the SMC, there was a slight positive change in results, around 3% compared to the base scenario. The analysis from the perspective of the distributor and the State, in addition to the SMC already performed, proposed scenarios with reduction and increase of the tariff value, which allowed to verify reduction of revenue loss and collection, as well as a performance decrease of the financial indicators. This enables the discussion of trade-off between tariff reduction for customer retention in the current system versus tariff increase or maintenance and the possibility of customer migration to the photovoltaic solar power generation system.

  • The use of fluorescent lamps showed significant growth after the 2001 energy crisis. This brings, on the one hand, a reduction in energy consumption and an increase in competitiveness for organizations and, on the other hand, a concern for modern society, because the irregular disposal of these after-consumption lamps can cause environmental and people's health damage. In this sense, the aim of this work was to analyze the process of discarding fluorescent lamps from the user and non - generating industries of fluorescent lamps in the metropolitan area of Belo Horizonte. The study was carried out in a quantitative and qualitative approach, with a descriptive character and the data collection was done through the following techniques: bibliographic research, documentary research, semistructured interview, structured questionnaire application and technical visit. The participants of the study were representatives of the Special Waste Management, the Municipal Environment Secretariat, the company responsible for the decontamination of industrial light bulbs and the user and non-generating industries in the metropolitan area of Belo Horizonte. From the results, it is noticed that the disposal of fluorescent light bulbs still does not occur the way it should. Ordinary waste is still the predominant disposal option, with 33% of the total and many respondents unknown of environmental legislation, portrayed in the National Solid Waste Policy and the Environmental Crimes Law. The industries also pointed out that there are many difficulties to implement reverse logistics, and the absence of public power programs that encourage the correct disposal cited by almost all companies (95%). With this, the disposal is inadequate and lacks communication and supervision by the public authorities.

  • Discussions about the concept of space in the market dynamics, although still incipient, have been increasingly recurrent. Until recent times, it was common for researchers in the field of consumer culture to focus their studies on consumers and producers, neglecting the fact that other agents could also play a significant role in changing markets. Current research, however, has positioned differently by highlighting previously unnoticed agents, such as space. If initially it emerged as a mere scenario of consumer relations, in recent studies space is approached as a central focus, assuming a relevant role as a transforming agent of the markets. Accompanying this understanding, the objective of this study was therefore to understand how the use of public spaces affects the behavior of consumers and, consequently, changes the market. To reach it, was used the context of the street carnival of Belo Horizonte, a collective movement that occupies the public spaces of the city in order to question the uses commonly associated with them. Based on the concept of social movements from an institutional perspective, a longitudinal investigation was carried out by collecting data from various sources, such as newspaper articles, Internet, public documents, semi-structured interviews and participant observation. As a result, three positions assumed by consumers directly influenced by the use associated with public spaces were identified: the organization of a social movement, the projection of institutional entrepreneurs and the promotion of institutional works. This research contributes to the understanding that socio-cultural structures influence the process of market evolution and should be considered in the decision-making of companies and governmental institutions.

  • Researchers in the field of consumer culture had investigated how we choose objects, gave them personal meanings, and removed of commodity status, became singularized. There are also studies that have focused on the moving of the singularized objects to the state of the commodity, being (re) commodified or discarded. Following the present research, the study search how second hand objects commercialized in the market return to their singular status, as happens the movement of objects in the market, and how consumers (re) singularize these goods. To reach the objectives proposed here, a qualitative research was carried out during 18 months focusing on the second hand clothing and accessories market. The data was collected through in depth interviews, netnography and participant observation and was analyzed using a hermeneutic perspective. As a result, the research verified that the objects are in transit in the state of the commodities and in the singularization, depending on the biographical phase in which it finds itself. The market of a second hand promotes attempts to objects (re) singularization through two main segments: (1) recovery of the object biography and (2) reinforcement of authenticity. The results also revealed that there is a movement of the object between classes, since, on context studied, a high class promoting a (re) commercialization of clothes and accessories of famous brands, vintage and high couture, making available as for the market of a second hand. The middle class then takes up the unique and special status, as it would not be possible to acquire them in the market of new products. The results of the research, especially in the understanding of consumer practices and the used objects market, contribute to the marketing decision process. Thus, the consumption of goods is shown as one of the main social mechanisms of distinction between classes and the movement of the object reflects such positioning.

  • Currently, it is noted that the business location scenario is experiencing changes. While for some industries location is defined by the proximity of its feedstock source, by the market, or by economies of agglomeration with significant strategic impact, the technology-based companies, the emerging businesses and here named as startups, suffer from less determinism and can hypothetically locate themselves anywhere they have access to the information and communication technologies. However, there is a trend towards clustering and the formation of startups ecosystems. To study this phenomenon, was made the option to understand the decision-making process of the location of these companies. The objective of the research was to investigate the rationality and the circumstances of the location decision taken by the entrepreneurs of technology-based companies not only for the implementation, but also for the continuity of the business. The limited rationality of the decision-maker, who is immersed in a set of institutions and under a network of connections with other agents, which at the same time restricts and potentiates their actions, has been accepted. The research was developed through the exploratory-descriptive case study of the San Pedro Valley Community, in the region of Belo Horizonte, Minas Gerais - selected for its prominence among Brazilian technological environments. Ontologically, reality was assumed to be the one perceived and interpreted by the actors, placing this study in the interpretive epistemology, with the use of multimethods, including the quantitative method, more associated with functionalism. Statistical analysis of data obtained through a survey; sociometric analysis; content analysis of primary interview data; besides analysis of secondary data, obtained in electronic sites and registries were used. At the end of this study it was possible to infer that the decision-making process of localization of startups by their founders is rational, according to the terms of limited rationality based on values. The main values considered were relationship networks, family and friends, as well as being born or established in the city. It was noticed that there is a tendency of the influence of the historical trajectory in the decision to remain in the place of origin. And once settled in the city, the decision to change becomes more difficult. The decision to stay in the city is supported by the existence of an entrepreneurial ecosystem, whose most outstanding actors were the universities as trainers of qualified workers; business accelerators and business acceleration programs as new business supporters and the networked entrepreneurs themselves in the San Pedro Valley community. The community was characterized by its collaborative culture that favors the exchange of information, knowledge, experiences and technology, as well as giving visibility to participants and to the city itself. It can be concluded that social capital is generated and maintained in the network differently by central and peripheral members, but all benefit collectively, whether by paying less taxes or being recognized by the reputation of the Community.

  • Supply chain management is a more complex management aspect, since in addition to people, products, services, information, facilities, production, distribution centers, supplier relations and customer relations, the chain is also included in several other systemic environments. In this way, this study is analyzed on the impact of the practices of management of competences on the competitive differential and the organizational performance. Medium the capacity of companies integrated in their networks of commercial relationships raises the following problem: What is the impact of the practices of management of profits on the competitive differential and the organizational performance? To answer a question, the context of the metalworking companies of the Minas Gerais state was studied. The research is of an applied nature, with the quantitative approach, using a Structural Equation Modeling as an application of analysis through surveys. Data from the study were collected from 269 companies to test three hypotheses. The results are higher than the SGM practices that may have improved the differential, but did not have a greater impact on the organizational order. In addition, competitiveness can have a direct and positive impact on organizational performance.

  • The dynamics of mobility in large Brazilian metropolises suffer from detrimental obstacles to the quality of life of the population and the economic development of cities. Belo Horizonte is an example of a city where the population faces problems in daily commutes. This research had as main objective to demonstrate the congestion tendency in the city of Belo Horizonte and to quantify its financial impacts and as it is the behavior of the public management as the investment decisions to reduce this externality. The results found emphasized the effects of congestion related to fuel consumption, emission of pollutants and the time people lose in impoundments. Results that demonstrate great monetary significance of the congestion problem and the need for investments in urban mobility. The mobility that should be treated as a priority by public administrations for their importance of urban sustainability, but which is often treated in isolation and coexists with various conflicts of interest in city management. It should be emphasized that this research may contribute to the discussion about the importance of urban mobility and sustainable development in the city of Belo Horizonte. Likewise, it could provide input to discuss how decisions on the choice of investment of public resources are made and what alternative solutions could be adopted to reduce the serious problems of congestion.

  • This dissertation aimed to analyze how performance management occurs in the context of the modernization of the federal public sector in Chile and Portugal. To do so, the study was based on a theoretical framework that covers everything from the modernization of public administration to performance management, passing on people management. Performance management, as well as other people management subsystems, is criticized for using private sector management tools, based on a results-driven logic. From this point of view, it is understood that certain practices of the private sector, regarding the measurement of performance, can not be simply inserted in the scenario of the public administration. Performance management can then be considered as a puzzle, as a paradox, in which it is sometimes implicitly addressed in the studies on results-based management, but its focus is only on performance evaluation, unrelated to management (BOUCKAERT . Beyond this criticism, performance management can contribute to the achievement of the strategic objectives of the countries and its focus is upward, a trend that can be verified through the manuals produced; by the interest of consultants and professional organizations, both public and private; and OECD evaluations, which indicate that developed countries have emphasized performance rather than just processes, so that their servers meet the needs of citizens (OECD, 2003, see Carneiro, 2013). In Portugal, public administration reform was implemented during the Constitutional Government (2005-2009) and had as its objective the restructuring of human resources management, with an emphasis on its integration with budget management, which is an inclination of the OECD, while in Chile HRM practices are directed to ministries to a lesser extent than the OECD (Organization for Economic Cooperation and Development) average. The central human resources management sector, for the most part, coordinates policy but is also responsible for other issues, including payment and classification systems. Chile makes less use of strategic HRM practices than the average of OECD countries, and its prominence lies in the decentralization of public bodies, which may grant autonomy, but fragments the implementation of policies and practices in that country, since are not adopted by all organs. The work consisted in a qualitative-descriptive research in which 16 semi-structured interviews were applied in the countries of study and documents and legislation were used referring to the subject. Through the analysis it was possible to identify that Chile and Portugal have practices and personnel management policies that make reference to performance management, which is similar to other OECD countries. The study countries also have limitations to implement performance management and the results indicate that there are still processes to be perfected, such as performance appraisal and compensation.

In order to establish the percentage of return that compensates investors for the risk assumed when investing in the electric power distribution segment, the National Electric Energy Agency (ANEEL) uses the Capital Asset Pricing Model (CAPM) together with the Weighted Average Cost of Capital (WACC) as a methodology for calculating the cost of regulatory capital applicable to periodic tariff review cycles (CRTPs), which occur on average every four years. To conduct the calculation of the regulatory capital cost, ANEEL must first define the appropriate parameters to represent the components of the CAPM and WACC equations. In addition to the choice of parameters that will represent each variable of the mentioned equations, ANEEL needs to design, based on historical data, a value for each variable that represents the best future estimate of the respective parameter. Currently, the regulatory agency determines, in a discretionary manner, the appropriate time window for the calculation of the mean or median of the components of the WACC equation. However, the long time series of some components used do not present a steady behavior, that is, they do not present mean and variance constants over time, as well as absence of autocorrelation. Thus, the adoption of the average or median by ANEEL to project values may not indicate the best estimate for the cost of regulatory capital, since such statistical measures do not take into account changes in the characteristics of the time series. Considering this context, it was proposed in this study the use of the Auto Regressive Integrated Moving Average (ARIMA) model by the regulator, which treats both the stationary and non-stationary time series, to calculate the value of the component components of the regulatory WACC. The result of the projection of long time series using the ARIMA method indicated values different from those estimated by ANEEL for the cost of regulatory capital. In addition, the projected components presented a greater oscillation throughout the cycles of tariff revision.

  • This research proposes the reflection on women managers at a Federal University, through Maria Carmem and Gaia’s life stories. Both professors with a managerial position at a Federal University. This research is justified by the low number of studies about women's managerial position occupation in this institution and small number of women who occupies these positions at the University. The theoretical background discusses the themes: gender, feminism, patriarchy, women and work, women and managerial work, university management and academic manager at the University. From a qualitative perspective based in the life story method, this study intends to answer the question: What is being a female manager at a Federal University? The database was collected by life story interviews and documentary research using secondary information given by the interviewees and university studies. The interviews were conducted with two academic managers that hold managerial positions at the University. Now they hold the positions of rector and director of the University. As result, both of the academic managers lived and experienced the prejudice and discrimination for been women in occupation of top hierarchical positions at the University. However, the study shows the resistance of these women to climb and conquer high hierarchical positions. Far from exhausts the discussions, this study reaffirm the understanding that the Universities are spaces widely dominated by male and that are a lot of challenges to be faced by women to conquer management positions.

  • The objective of this work is to analyze how the member-leader relationship influences the organizational citizenship behavior of the employees of a public institution in the state of Minas Gerais, having as reference the LMX (Leader Member Exchange Theory) theory. This theory understands leadership as a process, arising from the interaction between leaders and members. When this process evolves to a high level of partnership, in which responsibilities and decisions are shared, employees tend to reciprocate the LMX relationship through organizational citizenship (OCB) behaviors. OCBs are defined as voluntary and spontaneous acts that benefit the organization and are based on a social exchange relationship. The relevance of studying OCBs is based on the assumption that they are essential to increase the effectiveness and efficiency of organizations, especially public organizations. Thus, to achieve the proposed goal, this research uses a qualitative approach, since it intends to understand the phenomenon from the perception of the subjects and the way they interact with the people around them. The research strategy was the case study. For the data collection, semi-structured interviews were carried out with 12 servers (not occupying managerial positions) and 4 managers (occupants of managerial positions) of a public institution. After transcription, the interviews were analyzed using the content analysis method. The results suggest that the LMX relationship exerts a preponderant influence on the behavior of organizational citizenship, given that the affective and professional respect characteristics of the LMX relationship influence the behavior of disclosure of a favorable environment to the organization in the external environment; The characteristic partnership was related to the behaviors of cooperation and self-training; And, finally, the characteristic of open communication was associated with individual initiative and organizational participation behaviors. It should be noted that the system protection behavior was not associated with any characteristics of the LMX relationship and could not be considered as organizational citizenship for public servants. Finally, the contributions to the academic environment and the management of people in the public sector are discussed, and suggestions are presented for the development of future research.

  • The objective of this dissertation was to analyze, in the context of public sector reforms, the processes of professionalization of senior managers. Based on the experiences of Chile and Portugal, we try to analyze these processes in order to understand the possibilities and limits of this professionalization. The professionalization of top management positions has gained central relevance in the public-sector reforms of several countries since they are part of the process of formulating and implementing public policies and, consequently, of decision making within governments. These leaders appear as elements of conduction and permanence of changes as they assist in the consolidation of strategic management and provide the accumulation of institutional capacities and the timeliness of policies. Promoting change within organizations requires leaders who are able to guide these changes. The development and consolidation of senior management in the public sector depends on reforms in the organizational structure, human resources rules, selection forms, managerial skills, performance and development management, as well as in the political and organizational culture of the sector public. The study consisted of a qualitative-descriptive study in which documents and semi-structured interviews were used as a form of data collection in both countries. From the analysis of the data it was possible to perceive that Chile and Portugal follow the path of the professionalization of public leaders in close steps. The processes that lead to this professionalization, from the structuring of systems directed to the leaders to the adoption of new practices of recruitment and selection, are similar in both countries, respond to the worldwide tendency found in the literature. The main point of convergence in the professionalization of the leaders of both countries is the search for merit and the combination of professional and political criteria in the selection and management of these leaders. However, countries are also approaching their limits and challenges encountered during this process. Some interviewees point out that despite the whole process of selection, skills and performance institutionalized and guided by the search for merit, political influence still prevails. In the end, the balance between political and professional criteria ends up weighing on the political side.

  • This study had the main objective to speculate about the construction of the careers today. Therefore, this work had, as a fundamental empirical condition, the rescue of the Life History, through the cutout in career trajectories, of subject workers who have lived the experience of choosing to give new direction to their careers throughout their professional life. The thread of this research is based on the understanding of the elements in the career decision-making and its relationship to changes in the work and labor world. Career studies are studies of social, organizational and individual changes. The construction of professional trajectories, then, is a complex phenomenon that involves not only the interconnection of career models and work relationships in a given society, but also the different logics and rationalities that can be used by subjects in career decision-making in specific milestones of these paths. From the assumptions of Alberto Guerreiro Ramos’ substantive approach and also from identifying elements of the different rationalities present in the subjects’ career decision-making, this research set out to answer the question: How do contemporary workers make decisions to construct their careers in the milestones of their professional paths? As results, it seems that the decision-making processes of contemporary workers throughout their career rely on the concomitant, and often conflicting, influence of elements of substantive and instrumental logics. The search for autonomy, the relationship with money, social patterns of success and ethical issues appear as prominent elements that permeate decisions; while motherhood appears as the main career milestone. The option to assume flexible labor relationships, as opposed to the CLT, presents itself as an artifice found by these workers to live in an organizationally planned world, without losing their space of personal self-realization, bringing them closer to the model of the parenthetical man. Finally, future research perspectives are presented.
