Finanças comportamentais: Diferenças da aversão à perda entre alunos de administração de empresas e gestão financeira

O objetivo desta dissertação é analisar aversão à perda dos estudantes do curso de administração de empresas e do curso de tecnologia em gestão financeira, usando a reprodução do trabalho desenvolvido por Kahneman e Tversky (1979). Para tanto, foi realizada uma pesquisa em campo com estudantes em uma faculdade particular, localizada da cidade de São Paulo, onde pode ser aplicado o questionário no modelo original proposto pelos pesquisadores Kahneman e Tversky (1979) e através dos resultados obtidos, foi recriada a teoria dos prospectos e constatou que um grupo de estudantes tem uma aversão à perda menor. Neste trabalho, foi feita uma revisão bibliográfica sobre as principais mudanças na área financeira desde 1920 até atualidade, destacando a Teoria sobre Finanças Modernas, a Hipótese de Mercados Eficientes, Finanças Comportamentais, Heurísticas e Teoria do Prospecto. Os resultados apontam para a existência dos efeitos certeza, reflexo e isolamento. Foi possível confirmar a existência de um comportamento diferente para o grupo de estudantes de administração. Dentre as principais conclusões, os estudantes de administração, estão reagindo de forma diferente que os estudantes de gestão financeira. A formação dos respondentes mostrou-se um fator de diferenciação entre os dois grupos. Os alunos de administração tem uma base de estudos sobre finanças menor comparada com os estudantes de gestão financeira e uma base de estudos maior em outras áreas. Esse conhecimento mais abrangente na área financeira, não trouxe nenhum diferencial para os estudantes de gestão financeira, isso pode se dar por essa amostra ser basicamente de pessoas muito jovem que acabaram de sair do ensino médio e com pouca experiência e entendimento do mercado financeiro.

O IMPACTO DAS POLÍTICAS E PRÁTICAS DE RECURSOS HUMANOS SOBRE OS COMPORTAMENTOS DE CIDADANIA ORGANIZACIONAL

O objetivo deste estudo é investigar se as políticas e práticas de recursos humanos (PPRH) impactam os comportamentos de cidadania organizacional (CCO), a fim de proporcionar aos gestores uma compreensão de como os indivíduos, tão diferentes entre si, comportam-se dentro e fora da organização diante daquilo que lhes é estabelecido pela área de recursos humanos. No campo teórico, foram consideradas as obras de Milkovich e Boudreau (1994), Dessler (2002), Demo et al. (2012) entre outros para abordar a questão de PPRH e os trabalhos de Handy (1978), Organ (1990), Siqueira (2003) entre outros para a temática CCO. A metodologia utilizada nesse estudo trata-se de uma pesquisa quantitativa entre 156 trabalhadores de empresas públicas, privadas e mistas localizadas no Estado de São Paulo, sendo que para a captação dos dados foram aplicados questionários de autopreenchimento, composto por duas escalas, sendo uma voltada a PPRH (DEMO et al., 2012) e outra cujas questões são relacionadas a CCO (BASTOS et al., 2014). Como resultados, identificou-se que PPRH impacta de forma significativa CCO e que a política de envolvimento, que trata da criação de um vínculo afetivo entre a organização e seus colaboradores, contribuindo para o seu bem-estar em termos de reconhecimento, relacionamento, participação e comunicação (Demo et al., 2012, p.38), é a única que impacta de forma significativa CCO, se comparados aos impactos causados pelas políticas de recrutamento e seleção, treinamento e desenvolvimento, condições de trabalho, avaliação de desempenho e remuneração e recompensas. Conclui-se também que o conjunto de PPRH impacta com maior significância os fatores de CCO denominados divulgação da imagem organizacional e sugestões criativas. Não houve impacto significativo entre PPRH e o fator cooperação com os colegas.

APLICAÇÃO DA TEORIA DOS JOGOS NA GESTÃO DE PESSOAS: UMA ANÁLISE DA VARIÁVEL SALÁRIO

Esta dissertação apresenta os principais aspectos da Teoria dos Jogos, mostrando sua aplicação como instrumento analítico na Gestão de Pessoas no que diz respeito à variável salário. Considera a organização e o trabalhador como conceitos gerais, sem identificar o setor de atuação, ramo de atividade, classificação jurídica em função do seu faturamento, total de empregados ou participação de mercado dessa organização. Da mesma forma o conceito trabalhador não recebe qualquer identificação em relação ao setor de atividade onde trabalha, função, salário ou formação profissional. A organização é toda estrutura que gera bens e serviços para a sociedade e o trabalhador é todo elemento que emprega sua força de trabalho na produção de bens e serviços. Os objetivos estabelecidos para este estudo são: identificar as possibilidades de aplicação da Teoria dos Jogos na Gestão de Pessoas considerando a variável salário como elemento de conflito entre a organização e o trabalhador; mostrar se a forma de representação extensiva é mais apropriada ou não para analisar o cenário de embate na decisão de contratar ou não o trabalhador ou pagar mais ou menos salário e a existência do Equilíbrio de Nash. A metodologia qualitativa com apoio bibliográfico e documental caracteriza esta pesquisa qualitativa quanto a metodologia de pesquisa. Os métodos qualitativos contribuem para interpretar fenômenos do cotidiano, podendo ser composto por dados simbólicos situados em determinado contexto. A pesquisa documental é uma contribuição importante ao estudo do tema proposto, já que a pesquisa qualitativa não é uma proposta rigidamente estruturada e isto permite que o pesquisador use a imaginação e criatividade para atingir o objetivo. Os resultados obtidos pela pesquisa dão conta de que é possível a aplicação da Teoria dos Jogos na Gestão de Pessoas considerando o embate entre os jogadores (o trabalhador e a organização) em torno do salário, conforme pode ser visto no capítulo 4 nas representações da matriz de payoff de um jogo estratégico e nas figuras 9,10,11,e 16. A representação na forma extensiva, constitui outro objetivo, indicando os payoffs entre duas decisões centrais representadas por X = flexibilização com renúncia dos direitos pelos trabalhadores e Y = flexibilização/adaptação/negociação, conforme figura 16. Ao analisar a figura, o gestor de pessoas percebe as estratégias existentes para a organização e trabalhador para a tomada de decisão, ao mesmo tempo em que pode avaliar a situação que esteja vivendo e fazer simulações em busca de novas propostas. Por fim, o Equilíbrio de Nash para a aplicação na Gestão de Pessoas é discutido no item 4.1.3, sendo possível verificar que tanto o trabalhador como a organização podem chegar a uma decisão favorável para ambos e manter seus objetivos pretendidos inicialmente. Na figura 17, esse equilíbrio é apresentado depois da tomada de decisão do trabalhador pela proposta feita pela organização na sequência O2 e o trabalhador ficou com o ramo de sequência T2 com o valor de 20 moedas. A potencialidade da Teoria dos Jogos na Gestão de Pessoas surge do fato de que quem atua em uma organização compartilha resultados bons ou ruins obtidos pelas escolhas alheias, escolhas individuais e pelas escolhas construídas coletivamente. Quando o trabalhador resolve produzir menos, a empresa sofre com a perda do lucro gerado pelo ritmo mais lento de trabalho. Para mudar esse quadro, a empresa toma a decisão de aumentar o salário e o trabalhador por sua vez desenvolve a tarefa com maior velocidade e em maior quantidade e ela pode retomar o seu lucro. Nesses jogos há cobranças de desempenho, exigência para atingir metas, pressões, conflitos com clientes e lideranças. Logo, a Teoria dos Jogos pode ser aplicada como instrumento para o gestor de Pessoas avaliar a situação vivida para a tomada de decisão que resolva a situação de embate.

Da maniva ao grolado: práticas produtivas e patrimoniais no processo identitário dos Tremembé de Almofala (CE)

The indigenous political scene in Brazil is undergoing transformations that need to be better analyzed by scholars in the field of the Social Sciences. The deficit in the policy of indigenous land demarcation emerges as the largest obstacle in the conquest of collective rights. Therefore, a study to analyze renewed strategies in the struggle for social rights, and their implications in local everyday life relations, is urgent. In this context, the aim of this research is to understand the current social dynamics of identity among the Tremembé people of Almofala, in the state of Ceará, Brazil, with a fieldwork conducted in the flour mill of the Casa de Farinha Comunitária project, in the Lameirão community. Specific aims are: a) to analyze the processes involved in the project in order to comprehend their meanings and appropriations as well as their everyday life and political uses; b) understand the strategies to fight for social benefits; c) analyze the local ethnic classifications grounding the construction of the Tremembé identity in Almofala. Methods deployed are ethnography of communities, used to apprehend the social production of networks of relationships, and a social cartography of practices. The realization of rights demanded by the indigenous populations in Brazil is intertwined with a process of social and legal legitimation their identity and cultural heritage. Such legitimation works as a safeguard mechanism of rights secured by the Constitution. Therefore, to own a “cultural heritage” is perceived as a “passport” to benefit from emerging rights. Amid this context, changes in the traditional processing of the cassava root, a productive practice shared locally by diverse social groups, is reified as cultural heritage by the Tremembé people of Almofala and their network of collaborators in the pursuit of accessing distinctive public policies. Furthermore, the research came across specific social arrangements of local subjects which unfolded internal struggles, enabling to understand the dynamics of the Tremembé of Almofala identity process.

Estudo da resposta Th17 no transplante renal alogênico: contribuição do eixo quimiotático CCR6/CCL20 e dos polimorfismos gênicos em IL17A e IL17RA

Kidney transplantation is the best treatment for patients who have lost kidney function. Renal transplant patients require accurate immunosuppressive drugs to prevent rejection. In this process T helper cells of the immune system perform key role in the immune response to the graft, and recently the Th17 cells has been investigated by production of IL-17 potent proinflammatory cytokine whose role in the rejection has also been described. Increased of Th17 cell expression has an important association with the development of rejection in renal microenvironment, however the likely mechanism is not well understood. This study aimed to evaluate the Th17 response from the influence of the chemotactic axis CCR6/CCL20 and genetic variants in IL-17 and IL-17RA. We conducted a case-control study involving 148 patients transplanted at the University Hospital Onofre Lopes/UFRN in which assessed by immunohistochemistry protein expression of IL-17 and chemokines CCR6/CCL20 and by PCR-RFLP genetic variants in IL17A and IL17RA. Our results showed no influence of genetic polymorphisms on the outcome of the graft or the protein expression of IL-17. In renal graft microenvironment found several sources producing IL-17: tubular epithelial cells, glomerular cells, neutrophils and cell interstitial infiltration, in turn the expression of chemotactic axis CCR6/CCL20 was restricted to the tubular epithelium cells. There was a slight positive linear correlation between the presence of IL-17 and expression of chemotactic axis CCR6/CCL20 in the microenvironment of renal graft. Therefore, we believe that, combined with our results, further studies with increased "n" sample and greater control over the variables involved in obtaining the renal specimen, can determine more clearly the influence of chemotactic axis CCR6 / CCL20 and polymorphisms in cytokines related to Th17 profile on the control of this cell subtype response in rejection processes to renal allograft.

Operações linguístico-discursivas em relatos retextualizados por alunos do ensino fundamental

The following paper attempted to investigate and discuss the possible improvements in the writing of students from the public network in the 6th grade of elementary school. This research was run in the professional master degree In Portuguese Language. Also based upon Genetic Criticism, this study attempting to analyze in which way and in which proportions the alterations done in the texts reveal and perspective capacity in the students as they replace, broad, remove or just move terms in their assignments. We tried to develop our analysis in the pragmatic perspective in which Textual Linguistic is included, investigating the texts and appreciating them as a construction process of meaning. Our theoretical discussion will be based on and socio-interactional conception of language (MARCUSCHI, 2008), as well as in the postulates of Analyze of Discursion (ADAM, 2010, 2008). It has also been used the theoretical assumptions taken from Genetic Criticism which regard the relation between text and genesis, due to the fact that it considers the text and a the result of a construction of progressive elaboration and the writing as an activity of constant movement (DE BIASI, [2000] 2010; GRÉSILLON, 1989; [1990] 2008; [1992] 2002; SALLES, 2008a). To assemble the data in this research we took into consideration the social variables related to the students and the sociocultural context. Nonetheless, this investigation point towards a real classroom situation where we tried to analyze the language functioning in application conditions, thus, giving us authority to describe more precisely the reality we lived in, which provided us with a more attentive look to the observed particularities. This description of the reality appreciated built a path that point to a research of qualitative data approach to which meanings deriving from interpretation were attributed. To conduct this research we resourced to the Action-Research process. The data are comprised of ten personal reports that were created from rewriting assignments, which constitutes a range of twenty texts assessed starting from the linguistic operations acknowledged by Generative Grammar and continued by Lebrave and Grésillon (2009). As result of this analysis, we identified the operation of adding more often than the other ones. The replacement and removal operations display a very close offspring. Nevertheless, the moving operation was scarcely used. These results, besides demonstrating linguistic creativity of the students, revealed that for a text to be seen as “concluded”, the writing student articulates new elaborations through these linguistic operators and that these movements of coming and going, of erasures and amendments contribute significantly for the teacher to approach the relationship the student keeps with his textual and discursive expression, and then, with that, to hold information that eventually provides individual and collective directions in school productions.

Fatores críticos de sucesso como antecedentes da aceitação de um sistema de informação em uma universidade federal

In recent decades the public sector comes under pressure in order to improve its performance. The use of Information Technology (IT) has been a tool increasingly used in reaching that goal. Thus, it has become an important issue in public organizations, particularly in institutions of higher education, determine which factors influence the acceptance and use of technology, impacting on the success of its implementation and the desired organizational results. The Technology Acceptance Model - TAM was used as the basis for this study and is based on the constructs perceived usefulness and perceived ease of use. However, when it comes to integrated management systems due to the complexity of its implementation,organizational factors were added to thus seek further explanation of the acceptance of such systems. Thus, added to the model five TAM constructs related to critical success factors in implementing ERP systems, they are: support of top management, communication, training, cooperation, and technological complexity (BUENO and SALMERON, 2008). Based on the foregoing, launches the following research problem: What factors influence the acceptance and use of SIE / module academic at the Federal University of Para, from the users' perception of teachers and technicians? The purpose of this study was to identify the influence of organizational factors, and behavioral antecedents of behavioral intention to use the SIE / module academic UFPA in the perspective of teachers and technical users. This is applied research, exploratory and descriptive, quantitative with the implementation of a survey, and data collection occurred through a structured questionnaire applied to a sample of 229 teachers and 30 technical and administrative staff. Data analysis was carried out through descriptive statistics and structural equation modeling with the technique of partial least squares (PLS). Effected primarily to assess the measurement model, which were verified reliability, convergent and discriminant validity for all indicators and constructs. Then the structural model was analyzed using the bootstrap resampling technique like. In assessing statistical significance, all hypotheses were supported. The coefficient of determination (R ²) was high or average in five of the six endogenous variables, so the model explains 47.3% of the variation in behavioral intention. It is noteworthy that among the antecedents of behavioral intention (BI) analyzed in this study, perceived usefulness is the variable that has a greater effect on behavioral intention, followed by ease of use (PEU) and attitude (AT). Among the organizational aspects (critical success factors) studied technological complexity (TC) and training (ERT) were those with greatest effect on behavioral intention to use, although these effects were lower than those produced by behavioral factors (originating from TAM). It is pointed out further that the support of senior management (TMS) showed, among all variables, the least effect on the intention to use (BI) and was followed by communications (COM) and cooperation (CO), which exert a low effect on behavioral intention (BI). Therefore, as other studies on the TAM constructs were adequate for the present research. Thus, the study contributed towards proving evidence that the Technology Acceptance Model can be applied to predict the acceptance of integrated management systems, even in public.

Produção de biomassa e exportação de nutrientes de Eucalyptus grandis e E. urophylla

Scientific research in forest production technology area search techniques that increase production per unit area, with high economic viability and reducing environmental impacts. When dealing with forest plantations, studies are needed in the production of biomass and its nutrient content, and these are data parameters for planning the environmental implications of different intensities of forest harvesting. Given the above, this study aimed to elucidate the production and export of biomass and nutrients for two species of the genus Eucalyptus (E. grandis and E. urophylla) grown in the southwestern region of Parana. For this, it was evaluated: the stock of biomass and nutrients in eucalyptus (wood, bark, branches and leaves) at 60 months of age; the export rate of nutrients; the calorific value and economic viability. The biomass and the largest eucalyptus nutrient stocks are predominantly allocated to the stem (wood + bark). The components of biomass showed different chemical compositions, generally being higher in the leaves and bark and lower in wood and branches components. As for the calorific value, the leaves had its calorific value statistically superior than the other fractions, followed by branches, wood and bark. The organic carbon content (C.O.) is directly connected to the calorific value, and the calorific value increases as its content increase. The wood had the highest nutrient use efficiency values, something highly desirable and of great interest to forestry. The leaves showed smaller nutrient utilization efficiency values, with the exception of Ca and Mg that were smaller in the bark, indicating the importance of maintaining these components in the soil after harvest. The wood fraction presents the biomass lower cost when considering the replacement of nutrients exported by its biomass. On the other hand, the leaf fraction showed NPK higher cost of replacement.

Qualidade física e matéria orgânica do solo em sistema de integração lavoura - pecuária submetido a doses de nitrogênio

The animal trampling favors the soil compaction process in sheep raising and crop production integrated systems. This compression has negative effects, hindering the development of roots, the availability of nutrients, water and aeration, causing production losses, making it essential for the assessment of soil physical attributes for monitoring soil quality. Soil organic matter can be used to assess the quality of the soil, due to its relationship with the chemical, physical and biological soil properties. Conservation management system with tillage, along with systems integration between crops and livestock are being used to maintain and even increase the levels of soil organic matter. For that, a field experiment was carried out over a Oxisol clayey Alic in Guarapuava, PR, from de 2006 one. experiment sheep raising and crop production integrated systems The climate classified as Cfb .. The study was to evaluate the soil physical properties and quantify the stock of soil organic carbon and its compartmentalization in system integration crop - livestock with sheep under four nitrogen rates (0, 75, 150 and 225 kg ha-1) in the winter pasture, formed by the consortium oat (Avena strigosa) and ryegrass (Lolium multiflorum) and the effect of grazing (with and without). The soil samples blades density evaluations, total porosity, macro and micro, aggregation and carbon stocks were held in two phases: Phase livestock (after removal of the animals of the area) and phase crop (after maize cultivation). The collection of soil samples were carried out in layers of 0-0.5, 0.05-0.10, 0.10-0.20 and m. Data were subjected to analysis of variance and the hypotheses tested by the F test (p <0.05). For the quantitative effect data regression and the qualitative effect used the test medium. In non-significant regressions used the average and standard deviation treatments. The animal trampling caused an increase in bulk density in the 0.10-0.20 m layer. The dose of 225 kg N ha-1 in winter pasture increased total soil porosity at 8% compared to dose 0 kg N ha-1 in the crop stage. The grazing had no effect on soil macroporosity. GMD of aggregates in the phase after grazing the surface layer was damaged by grazing. Nitrogen rates used in the winter pasture and grazing not influence the total organic carbon stocks. The TOC is not influenced by nitrogen fertilization on grassland. The grazing increases the stock of POC in the 0.10-0.20 m layer livestock phase and cause the stock of POC in the 0-0.5 m layer in the crop stage. The MAC is not influenced by N rates applied in the pasture or by grazing.

Sistemas de produção de milho sob adubação nitrogenada e plantas de cobertura do solo

The no-tillage system is the predominant model in the agricultural scenario of southern Brazil. Thus, the use of cover crops is significant due to the addition of biomass to protect the soil surface, and contribute to the cycling and/or fixing of nutrients, and in particular nitrogen (N) with liberation for the subsequent culture. Among the cool season species, it was found predominant use of oat to obtain straw to system. Though large quantities input of residue is not the preferred species to precede the corn, cereal with relevant importance in the Paraná Southwest region. It was aimed to evaluate the productivity capacity of corn in no-tillage, in the absence or presence of nitrogen fertilization, on waste of winter cover crops on soil and climatic conditions of the Paraná Southwest region. The installation of no-tillage was held in 2010 in the experimental area belonging to UTFPR, Campus Dois Vizinhos, on a Red Latosol. For the present study, we used data relating to three agricultural years (2012/2013, 2013/2014 and 2014/2015). The experimental design was randomized block design with split plots with three replications. The main plots consisted of systems composed by cover crops (black oat, ryegrass, rye, turnip, vetch, white lupine, aot+vetch consortium and oat+vetch+turnip), preceding corn. In the subplots were used two doses of nitrogen fertilization (0 and 180 kg ha N) coverage in maize.The biggest coverage rates occurred in the consortium with 95% at 62 days after sowing. The residual effect of 180 kg ha cool season plants following year. The residual effect of 180 kg ha systems, reduced in 21% the C/N ratio of poaceae. The common vetch accumulated 32 kg N per ton of MS added. The oat and rye keeps more than 50% waste to the land cover, after 120 days, while the ryegrass and vetch provide low soil protection. Consortium oat+vetch+turnip, vetch and white lupine, released the largest amounts of N, between 52 and 59 kg ha brassica and consortia positively influencing the diameter and length of cobs, number of kernels per row and, total number of grains per ear of corn, in the absence of mineral N. The weight of a thousand grains was increased by 12.4% by the addition of 180 kg ha increase in productivity of grain by the addition of 180 kg ha N, was 2.1 Mg ha 5.6 Mg ha 6.4 Mg ha components when cultivated on vetch.
