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

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.

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.

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.

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.

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.

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 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.

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 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 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 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 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.

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.

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.

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.

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.

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.

This work aims to propose models using machine learning techniques, specifically using artificial neural networks (ANN) and support vector machine (SVM), to predict financial assets which have potential to achieve specifics targets and then compose portfolios using the Black-Litterman model (BL). Regarding the the specifical aims, the propose is to build a model using ANN and another one using SVM to classifie financial assets which have potential to achieve specific targets, and then, optimize portfolios using BL model, taking as view parametrer the ANN and SVM predictions, and, finally, compare the portfolios with the baselines (Ibovespa index and a portfolio built using the Markowitz’s model). The sample was composed by assets in Ibovespa index, from January 2006 to July 2017, considering daily data. The ANN and SVM models operated as classifiers, where was daily generated achievment indicators from specificals targets. This predictions was coupled in BL model using the targets as a view parametre and the precision measure used to represent the confidence regardind this view. To compare the performance of the proposed model five other models were configured: (i) a model using signals from a randomic process coupled in BL model, (ii) a model using signals from the classifiers, but without optimization, (iii) a model using signals from the classifiers coupled in MV model, (iv) the MV model in simple application, and (v) a porfolio using a buy-and-hold strategy based in Ibovespa index. The results indicated higher performance from the classifier based on SVM when compared with a naive approach, superiority in terms of cardinality, operation volume and return for SVM+BL strategy, in a total period and by bienium analysis. This results reinforce the potential of using the soft computing techiniques in a portfolio selection process, providing insigths for the decision maker to elaborate more assertive strategies, performing a more accuracity operration and achieving better results. The contributions of this work include the proposition from a model to support the decision maker in a process of investment decision, the development of a classifier which has statitical superior assertivity if compared to a naive approach, the use of the minimun variance portfolio to estimate the market equilibrium distribution, and the coupled of the predictions from machine learning techiniques with the BL model, using the precision measure as parametre.

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.

The objective of this work was to propose a new methodology for the projection of the variables adopted in the calculation of the cost of capital of the Brazilian electricity distribution sector. 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.

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.

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.
