Entre o individual e o coletivo: carisma, memória e cultura

Embora já se tenha passado muito tempo, ainda hoje me recordo de minha avó dizendo com orgulho que em nossa família não havia “flamenguistas”, e nem “lacerdistas”. Símbolo de uma época em que a política tinha quase o mesmo poder de identificação do futebol, Carlos Lacerda teve como contraponto na acirrada política carioca dos anos 60 a figura de Leonel Brizola. Se o Fla-Flu enchia o Maracanã e inflamava as torcidas, não menos inflamado era o discurso que então alimentava a rivalidade entre lacerdistas e brizolistas na antiga capital federal. O objetivo do artigo é analisar a maneira pela qual Carlos Lacerda e Leonel Brizola se constituíram como lideranças carismáticas no Rio de Janeiro, procurando relacionar esse processo com a cultura política de uma cidade que por mais de um século fora capital do país.

A autonomia patrimonial na empresa individual de responsabilidade limitada (EIRELI)

O presente trabalho pretende demonstrar que o real avanço com o advento da previsão legal da empresa individual de responsabilidade limitada – EIRELI é a proteção conferida pela autonomia patrimonial e não a limitação da responsabilidade do comerciante. Visto que há uma escassez na literatura nacional a respeito do tema, iremos utilizar bibliografia norte americana como base para a primeira parte da pesquisa. Assim poderemos identificar as vantagens e desvantagens da responsabilidade limitada e da autonomia patrimonial para podermos concluir com uma análise de custo e benefício destes institutos jurídicos. Por fim, utilizaremos do conhecimento adquirido por toda esta análise para aplicarmos e adaptarmos as especificações da EIRELI. Nos apoiaremos em doutrina nacional somente em relação as regras de sociedades limitadas, pois a lei determina que estas serão usadas supletivamente para as empresas individuais de responsabilidade limitada. Com base nisso o trabalho será finalizado com uma questão pouco explorada, que é em relação a penhora e liquidação das quotas na EIRELI.

Brand image co-creation and individual identity extension in online environments: a Facebook investigation

In this thesis I investigate the extent to which companies can build a more communal environment out of their fan pages while also evaluating the corresponding brand value that may come from having such a communal environment. My research is comprised in three articles: in the first article, I describe how the brand image is created or augmented in the fan page environment, therefore providing demonstrable evidence of value creation. In the second article, I describe how individuals use fan page semiotic elements to communicate their identities. Finally, in the third article, I describe the possible communal characteristics of a fan page and the conditions that enable it to evolve to the virtual brand community concept. As a result, I will contribute to the marketing literature on the use of Facebook for communicating brand identity, on the co-creation of the brand image in social media context, and on the conceptual definition of fan pages as a communal environment.

Preferência por redistribuição afeta a decisão individual de voto?

Parte dos estudos em economia e ciência política argumenta que preferências por redistribuição são capazes de explicar os diferentes esforços redistributivos ao redor do mundo. É natural pensar que a decisão de voto é o único canal relevante para que esta argumentação seja válida. Este trabalho buscará evidências empíricas de que haja correlação entre preferências por redistribuição e a decisão individual de voto nos Estados Unidos. Primeiro, apresento um modelo teórico que faz ligação entre a identificação partidária do indivíduo com seus interesses próprios e coletivos. Com base neste modelo, serão usados dados do General Social Survey para encontrar tais relações. Nos resultados encontra-se que as preferências por redistribuição estão relacionadas à identificação partidária e, consequentemente, à decisão de voto por redistribuição. Há também alguma evidência de que esta influência esteja crescendo nas últimas décadas.

Inattention in individual expectations

This paper investigates the expectations formation process of economic agents about inflation rate. Using the Market Expectations System of Central Bank of Brazil, we perceive that agents do not update their forecasts every period and that even agents who update disagree in their predictions. We then focus on the two most popular types of inattention models that have been discussed in the recent literature: sticky-information and noisy-information models. Estimating a hybrid model we find that, although formally fitting the Brazilian data, it happens at the cost of a much higher degree of information rigidity than observed.

Avaliação do grau de sofisticação do investidor individual pessoa física na negociação de produtos de renda variável

O presente trabalho analisa o grau de sofisticação do Investidor Individual, subclasse da Categoria “Pessoa Física”, na negociação de produtos de renda variável no período compreendido entre Janeiro de 2006 e Dezembro de 2014. Através da análise de dados diários dos fluxos líquidos de investimentos, encontramos evidências que reforçam a hipótese de baixa sofisticação do Investidor Individual, no que diz respeito à diferença de atuação, de maneira agregada, entre ele e o investidor tido como mais qualificado (i.e., Investidor Estrangeiro), além de confirmarmos o ditado popular de que ele “Compra no Topo e Vende no Fundo”. Adicionalmente, encontramos evidência de causalidade entre, de um lado, a evolução do fluxo financeiro (tanto na compra quanto na venda), e do outro, variáveis como Retorno e Volatilidade, no sentido do primeiro causar estes. Os Testes de Causalidade de Granger e Impulso Resposta corroboram o indicado nas regressões; revela-se adicionalmente que um choque positivo na Volatilidade impacta negativamente as variáveis dependentes, de maneira crescente, por até 21 dias de pregão.

Ecologia trófica em uma taxocenose de anfíbios: estrutura, filogenia e especialização individual

Historically, ever since the pre-Darwinian naturalists interspecific competition was considered the main force responsible for structuring ecological communities. This interpretation lost strength in the late 70s and throughout the 80s giving room for other views, which consider other factors such as predation, parasitism and the phylogenetic inertia more important. Studies on changes in the trophic niche of a species are still uncommon in general and especially in amphibians. Species considered generalist might actually be a group of individual specialists, or individuals that specialize in a particular category of prey during a period of scarcity of resources, thus reducing intraspecific competition. This work studied the community structure of litter amphibians and trophic variation along the dry and rainy seasons in a population of Leptodactylus macrosternum. Sixteen-litter frog species were studied for their diet. Two central assumptions were tested: 1a) if the community is structured in the niche trophic level, and 1b) if there is a significant difference in the use of food resources by different species (i.e. if the community is structured), the observed structure is the result of ecological interactions or just the current phylogenetic inertia of species. Finally, 2) if there is variation in food resource use between seasons for L. macrosternum. The community showed a structure with respect to the use of food resources, and this structure persisted after taking into account the phylogenetic relationships among species. The diet of Leptodactylus macrosternum varied with the seasons, with a significant degree of individual specialization for the dry season. Patterns of a local community are important to understand its dynamics, and this may play a role in larger- scale processes. Therefore, the studies in community ecology are fundamental to understand and eventually restoring degraded areas

Estilo de vida individual de universitários jovens com excesso de peso da Universidade Católica de Murcia-Espanha

Individual lifestyle includes health and risk behaviors that can altar health status. Excess weight is a public health problem of modern civilization and there is an estimated mean prevalence of 45% in European countries. In Spain, the Murcia Region is an area of high morbidity and mortality from cardiovascular disorders. In this study we assess the differences in health and risk behaviors in ove/weight and normal weight undergraduates at the Universidad Católica San Antonio de Murcia (UCAM). Methods: Transversal design of parallel groups (overweight - cases and normal weight - control) , formed using the anthropometric technique. A questionnaire applied to a sample of 471 undergraduates of either sex, between the ages of 18 and 29 years, enrolled in 4 bachelor degree courses (ADE, CA, PER, PUB) at UCAM. We performed a standardized measurement of body mass (weight in kg), height (in meters) using a Seca® scale with calibrated stadiometer, waist and hip circumferences (in cm) with an inelastic tape and skinfolds thickness (triceps and subscapular in mm) with a Holtain® caliper, to calculate body mass index (BMI), waist-to-hip ratio (WHR) and the sum of skinfolds (SSF). We applied a lifestyle questionnaire about alcohol and tobacco consumption, knowledge and behaviors related to health indicators (arterial pressure and cholesterol), diet and physical activity. The information was collected in April and May, 2001 at the UCAM laboratory of Applied Nutrition. Statistical analysis: analysis of independent groups, contingency tables that reveal which qualitativa variables show differences and associations between the groups, Pearson's chi-square,and a significance levei of p < 0.05 followed by a residual analysis (1.96). Descriptive statistics (mean and standard deviation) were used to establish the two groups: case and contrai with 65 men and 26 women each who had BMI < 25 kg/m2. Results: A total of 65 of the men assessed (14%) and 26 (6%) of the women were overweight. Mean body mass index of the case group was 27. 78 ±: 2.83 kg/m2 in the men and 26.26 ± 1.37 kg/m2 in the women, while contrai group men had mean BMI of 22.36 ± 1.72 kg/m2, while for the women it was 20.76 ±: 2.13 kg/m2. The self-declared values of weight and height were underestimated, but with high accuracy, sensitivity and specificity. Thus, these can be used to calculate the BMI of overweight Spanish undergraduates. Regular vigorous physical activity was observed only in normal weight men. The analysis showed the following significant differences for the qualitativa variables of the two groups. The contrai group was interested in arterial hypertension, believed that they were not overweight, that they had no abdominal fat, and had not considered controlling 'fatty food consumption. Those who thought of controlling it sometimes, did so without professional help. However, part of the overweight group believed that they were overweight and had abdominal fat between average and considerable, had often or always considered controlling fatty foods and had often or always tried to control consumption with the help of professionals. They had always thought of engaging in physical activities, unlike the normal weight individuals. Nearly all (95%) of the overweight undergraduates and most (75%) of the normal weight group reported that they sometimes or always controlled fatty food ingestion. Mean physical activity was nearly twice as high in the summer than in the winter. Conclusions: The overweight undergraduates in this sample displayed a lifestyle with a greater number of healthy behaviors when compared to normal weight individuals

Thermal comfort indices in individual shelters for dairy calves with different types of roofs

Dentre os materiais de construção utilizados nas instalações rurais, merecem destaque as coberturas, pois são grandes responsáveis pelo conforto térmico, influenciando no balanço térmico no interior das instalações. Este trabalho objetivou avaliar a influência das coberturas sobre a entalpia (H), Carga Térmica Radiante (CTR) e no Índice de Temperatura de Globo Negro e Umidade (ITGU), em abrigos individuais para bezerros leiteiros. O delineamento foi o inteiramente casualizado com três tratamentos: Z - telha de zinco; CA - telha de cimento amianto, e CAB - telha de cimento amianto pintada de branco na face superior. As médias foram comparadas pelo teste de Scott Knott, a 1% de probabilidade. Os resultados mostraram que não houve diferença estatística entre os tratamentos (P<0,01) e o ambiente externo, para a H. Para a CTR, houve diferença estatística entre todos os tratamentos, em que CAB demonstrou menor CTR, 489,28 W m-², seguido do tratamento CA, 506,72 W m-², e Z com maior valor de CTR, 523,55 W m-². Para o ITGU, observaram-se menores valores para CAB (76,8) e CA (77,4), diferindo-se, significativamente do Z, que obteve maior valor (81,6). As telhas com pintura branca em sua face superior promoveram menor CTR e menor ITGU, favorecendo o ambiente térmico da instalação.

Ofício, Estresse e Resiliência: desafios do Professor Universitário.

The objective of this study was to investigate the elements that contribute to the state of stress which often affects those who embrace the university teaching career, and also to learn whatever strategies professors use to cope with stressing situations in order to develop resilience and a sound exercise of their profession. To the very nature of university teaching belong a variety of attributions, demands and challenges which, together, may contribute to the development of stress. The epistemological principles which guided this research were those of Complex Thinking, which facilitate a deeper comprehension of the human and social phenomena as viewed through the lens of complexity principles: the dialogical principle, the organizational recursivity principle and the hologramatical principle. Fully acknowledging the many difficulties brought about by any attempt that would try to explain human phenomena based only on one theoretical reference, we have elected multi-referentiality as the support for this study, thus being able to dialogue with a variety of authors about the same phenomenon. This was a qualitative research in which questionnaires and interviews were used as instruments for the empirical work. The data has been articulated into categories and subcategories, allowing for a thematic analysis. Participants of the study were seventeen professors from two different colleges in the city of Natal, state of Rio Grande do Norte. Bad working conditions, demands from the institution, student s lack of commitment, long working hours, low salaries, lack of incentives to university teachers, uncertainty concerning timetable and difficulties in proper time administration are the variables that contribute to the stress of professors. Although this is a problem that affects the group as a whole, strategies to cope with it are individually sought and vary from trying to find different leisure options, opening one s heart to colleagues or relatives, individual planning, prayer, rational facing of the situation, to simply giving in to exhaustion. The study has proposed institutional as well as personal actions that may foster a development among professors which takes into account a resilience development in a collective perspective. Also, it shows some articulations that are already under way so that professors may be attended to.

Detecção de anticorpos contra o vírus da diarréia viral bovina no soro sangüíneo, no leite individual e no leite de conjunto em tanque de expansão de rebanhos não vacinados

Pela pesquisa de anticorpos contra o vírus da diarréia viral bovina (BVD), utilizando o teste de ELISA indireto, foi estudada a correlação existente entre a proporção de vacas lactantes e a presença de anticorpos no leite de conjunto do tanque de expansão. Para isso foram analisadas amostras de soro sangüíneo e de leite individual de 376 vacas lactantes não vacinadas, provenientes de 10 propriedades localizadas nas regiões Sul do Estado de Minas Gerais e Nordeste do Estado de São Paulo, assim como uma amostra do leite do tanque de expansão de cada rebanho. em todas as propriedades foram encontradas vacas reagentes no soro sangüíneo, cuja freqüência variou de 12,28 a 100,00%. Já a análise do leite individual não revelou animais reagentes em duas propriedades, e nas demais a freqüência variou de 5,26 a 70,83%. Foram detectados anticorpos no leite do tanque de expansão das propriedades cuja proporção de soros sangüíneos reagentes foi igual a ou maior que 82,86%, e cuja proporção de leites individuais reagentes foi igual a ou maior que 32,14%.
