UN Security Council decision-making: testing the bribery hypothesis

Liberal-Institutionalism and Structural Realism expectations about international organizations are confronted by looking at if and how US-controlled international aid is granted, and particularly if it is related or not to political affinity and to United Nations Security Council (UNSC) non-permanent membership. A preliminary assessment suggests that these relations only hold for the period of the Cold War, and, even then, only when UNSC non-permanent membership is in years in which the Security Council was deemed very important.

Do stakeholders matter in strategic decision making of a sports organization?

This study aims to identify and prioritize the stakeholders involved in making decisions in a sports organization. A multiple linear regression analysis was used to assess the influence of the attributes of power, legitimacy and urgency on the salience of the various stakeholders. The results showed a convergence of external and internal decision makers' perceptions, concerning the three main stakeholder groups: top management, sponsors and member association. Pearson correlations identified four types of stakeholder: definitive, dangerous, demanding and non-stakeholders. A generalized differentiation was also found in stakeholder classification, regarding evaluation of attributes, between external and internal decision makers. In addition, the study suggests the success of organizations' management will depend on correct identification of stakeholders and consequent assessment of their relevance, in order to highlight who should get priority, and how, in strategic decision making.

DISPOSITION EFFECT AMONG BRAZILIAN EQUITY FUND MANAGERS

The disposition effect predicts that investors tend to sell winning stocks too soon and ride losing stocks too long. Despite the wide range of research evidence about this issue, the reasons that lead investors to act this way are still subject to much controversy between rational and behavioral explanations. In this article, the main goal was to test two competing behavioral motivations to justify the disposition effect: prospect theory and mean reversion bias. To achieve it, an analysis of monthly transactions for a sample of 51 Brazilian equity funds from 2002 to 2008 was conducted and regression models with qualitative dependent variables were estimated in order to set the probability of a manager to realize a capital gain or loss as a function of the stock return. The results brought evidence that prospect theory seems to guide the decision-making process of the managers, but the hypothesis that the disposition effect is due to mean reversion bias could not be confirmed.

"Caindo na cana" com Marilyn Monroe: tempo, espaço e "bóias-frias"

Neste artigo pretendo discutir um drama social ("cair na cana") que marca a passagem para uma condição ambígua, liminar. Se uma das experiências associadas ao "modernismo" é a de vivermos simultaneamente em tempos e espaços diferentes, certamente os "bóias-frias" são nossos contemporâneos modernistas. Paradoxalmente, em se tratando de uma imagem que certamente seduziu alguns campos intelectuais durante os anos 70 e 80, teriam as tentativas de definir o "bóia-fria", transformando imagem em categoria, contribuindo para a sua constituição em uma espécie de fóssil recente da produção academica?

Saúde de famílias do Movimento dos Trabalhadores Sem Terra e de bóias-frias, Brasil, 2005

OBJETIVO: Avaliar as condições de saúde de famílias ligadas ao Movimento dos Trabalhadores Rurais Sem Terra e de bóias-frias. MÉTODOS: Realizou-se estudo comparativo de três populações: assentamento e acampamento do Movimento dos Trabalhadores Rurais Sem Terra, e famílias de bóias-frias, em Unaí, MG, em 2005. Foram coletados os dados referentes às características sociodemográficas e familiares por meio de questionários aplicados a 202 famílias, e realizadas observação estruturada e discussões em grupo. Realizou-se a análise fatorial discriminante para se verificar diferenças entre as comunidades. RESULTADOS: As três comunidades apresentaram uma média de 89%, caracterizando-se como grupos distintos e reforçando a hipótese de que são realmente diferentes entre si em termos de suas condições de vida e saúde. Os trabalhadores bóias-frias apresentaram um alto índice de insegurança alimentar (39,5%), quase o dobro da proporção entre as famílias acampadas e quatro vezes mais que as assentadas. Com uma renda variável e baixa, os bóias-frias estavam mais expostos aos agrotóxicos se comparados aos assentados e acampados. A produção animal desenvolvida por todas as famílias assentadas foi uma característica marcante, ao contrário das famílias bóias-frias que praticamente não contavam com essa possibilidade na cidade. Segundo a percepção das famílias assentadas e acampadas, o Sistema Único de Saúde não tem atendido as necessidades de saúde da maioria delas, principalmente pela dificuldade do acesso aos serviços. Para esse grupo, o atendimento de suas necessidades se dá após reivindicações e pressões sobre os governos. CONCLUSÕES: Segundo a percepção das famílias do Movimento dos Trabalhadores Rurais Sem Terra, o fato de ser do Movimento e estar organizado melhora suas perspectivas de saúde, em comparação aos bóias-frias. Os resultados da modernização conservadora no campo brasileiro têm agravado as condições de vida dos bóias-frias gerando uma superexploração do trabalho humano, enquanto que a Reforma Agrária tem possibilitado uma melhor qualidade de vida e saúde para as famílias, quando comparadas nas áreas estudadas.

Decision-making on childhood vaccination by highly educated parents

OBJECTIVE To analyze the sociocultural aspects involved in the decision-making process of vaccination in upper-class and highly educated families.METHODS A qualitative approach based on in-depth interviews with 15 couples from the city of Sao Paulo, Southeastern Brazil, falling into three categories: vaccinators, late or selective vaccinators, and nonvaccinators. The interpretation of produced empirical material was performed through content analysis.RESULTS The study showed diverse and particular aspects surrounding the three groups’ decisions whether to vaccinate their children. The vaccinators’ decision to vaccinate their children was spontaneous and raised no questions. Most late or selective vaccinators experienced a wide range of situations that were instrumental in the decision to delay or not apply certain vaccines. The nonvaccinator’s decision-making process expressed a broader context of both criticism of hegemonic obstetric practices in Brazil and access to information transmitted via social networks and the internet. The data showed that the problematization of vaccines (culminating in the decision to not vaccinate their children) occurred in the context of humanized birth, was protagonized by women and was greatly influenced by health information from the internet.CONCLUSIONS Sociocultural aspects of the singular Brazilian context and the contemporary society were involved in the decision-making on children’s vaccination. Understanding this process can provide a real basis for a deeper reflection on health and immunization practices in Brazil in light of the new contexts and challenges of the world today.

Local Rainfall Variability - A Potential Bias for Bioecological Studies in the Central Amazon

Rainfall data registered betwe en 1910 and 1979 at Manaus confirm the existence of a dry season between June and November (monthly rainfall: 42-162mm) and a rainy season from December until May (monthly rainfall: 211-300mm). Annual precipitation amounted to 2105mm with about 75% of the rainfall recorded during the rainy season. Rainfall data collected over 12 months at eigth stations in the vicinity of and at Manaus are compared. Annual precipitation was lower in Inundation Regions (1150-2150mm) compared with Dryland Regions (2400-2550mm). Considerable differences are found in rainfall patterns (intensity, frequency and time of rainfall). This is also truefor neighbouring stations, even if data of a 11-year record period are compared. Thus, it is highly recommended that preciptation data for bioecological studies be collected at the study site.

Normal aging and decision-making: a systematic review of the literature of the last 10 years

Objective Conduct a systematic review to investigate whether healthy elderly have deficits in the decision-making process when compared to the young. Methods We performed a systematic search on SciELO, Lilacs, PsycINFO, Scopus and PubMed database with keywords decision making and aging (according to the description of Mesh terms) at least 10 years. Results We found nine studies from different countries, who investigated 441 young and 377 elderly. All studies used the IOWA Gambling Task as a way of benchmarking the process of decision making. The analysis showed that 78% of the articles did not have significant differences between groups. However, 100% of the studies that assessed learning did find relevant differences. Furthermore, studies that observed the behavior of individuals in the face of losses and gains, 60% of articles showed that the elderly has more disadvantageous choices throughout the task. Conclusion: The consulted literature showed no consensus on the existence of differences in performance of the decision-making process between old and young, but it is observed that the elderly has deficits in learning and a tendency to fewer advantageous choices.

Network Meta-analysis to Synthesize Evidence for Decision Making in Cardiovascular Research

Abstract Clinical decision-making requires synthesis of evidence from literature reviews focused on a specific theme. Evidence synthesis is performed with qualitative assessments and systematic reviews of randomized clinical trials, typically covering statistical pooling with pairwise meta-analyses. These methods include adjusted indirect comparison meta-analysis, network meta-analysis, and mixed-treatment comparison. These tools allow synthesis of evidence and comparison of effectiveness in cardiovascular research.

Effect of bird density on the decision to join a group in the Sicalis flaveola pelzeni (Passeriformes, Emberizidae)

A change in bird density within a captive flock of Sicalis flaveola pelzeni (Sclater, 1872) affected the decision to join a group. Ruling out inter-individual differences and maintaining constant the size of a food patch, birds were found to fly more often to the food source and spend a longer time in its environs when kept in greater groups.
