We estimate optimal target-ranges of capital structure controlling for a series of firmspecific characteristics and accounting for the serial correlation that arises from the dynamic component of the leverage choice. Then, we empirically examine if firms adjust their leverages toward the estimated optimal ranges. Our analysis suggests that the observed behavior of firms is consistent with the notion of range-adjustment.

Este estudo versa sobre a controvertida relação elitre a desnutrição e a aprendizagem procurando identificar os pontos em comum, ou não, entre essas duas áreas. O objetivo deste trabalho é contribuir com fundamentos teóricos e práticos que possibilitem a análise e reflexão do tema apresentado. Observamos que há diferentes abordagens sobre a relação desnutrição e aprendizagem e, p~ ra cada dimensão do problema estudado, procuramos oferecer as reflexões necessárias ao processo ensino-aprendizagem. O trabalho apresenta, também, alguns dados provenientes de uma pesquisa de campo realizada pela autora com professores e orientadores educacionais de diversas escolas do Município do Rio de Janeiro. Embora a pesquisa, em si, não tenha sido o fio condutor deste estudo, seus resultados, entretanto, poderão servir como colaboração e subsídio aocontextualmente, a partir de sua própria realidade. Sem ter a pretensio de ter esgotado ~odo o referencial teórico sobre o assunto, esse estudo teve, também, a finalidade àe provocar o debate sobre'o tema, oferecer subsídio aos professores, assim como propiciar meios novas pesquisas nesta área. para Há que ressaltar que o problema da desnutriçio envolve variáveis de outros setores tais como: social, poli tica, econômica e cultural, portanto, ele nao pode ser analisado isoladamente; e seu estudo requer, por conseguinte, aprofundamento também nas outras áreas. As duas suposições de trabalho, levantadas no iní cio do estudo, continuam em aberto porque, apesar da desnutriçio nao ser a única responsável pelo fracasso escolar, ela,.a desnutriçio, provavelmente, será u~ dos fatores prejudiciais ao desempenho satisfatório do aluno. tema estudado.em trabalhos posteriores. De acordo como levantamento teórico, podemos con cluir que não existe um consenso a respeito da relação desnu trição e aprendizagem, pois, os próprios autores, nao excluem de suas análises os pontos referenciais das outras abordagens. Observa-se, então, que este tema, tão rico e tão polêmico, ainda não oferece uma dimensão única sobre seus resultados, devendo o educador, por isso mesmo, trabalhá-lo,

Recruiters make many inferences about applicants' abilities and interpersonal attributes on the basis of applicants' resumes. For example, every once in a while, a good resume leaves a strong positive impression and the recruiter creates a high expectation for the selection interview. What if a disappointing interview follows? Will the great resume help or hurt the candidate? The purpose of this study is to assess the impact of a good resume on the recruiter’s evaluation of a candidate when a non-enthusiastic interview follows as well as the interacting role of gender. The results of two online experiments (n=454) where participants played the role of the recruiter, showed that, on average, a very good resume (vs. no resume) before a non-enthusiastic interview did not affect the recruiter’s evaluation of the candidate. However, when the recruiter’s and the candidate’s gender were taken into consideration, a different picture emerged. While no effect was found for male recruiters, the candidate’s resume had a clear significant impact on female recruiter’s evaluations: when the candidate was also a female, the good resume shown before the non-enthusiastic interview performance tended to help, whereas when the candidate was a male, the good resume had a significant negative effect on female recruiters’ evaluation of the candidate. In sum, in situations where the resume had a strong impact on the recruiter’s evaluation (female recruiters), the direction of the effect was moderated by the candidate’s gender. Gender differences in information processing as well as in-group/out-group biases due to gender matching are used to hypothesize and explain the main findings.

Choosing properly and efficiently a supplier has been challenging practitioners and academics since 1960’s. Since then, countless studies had been performed and relevant changes in the business scenario were considered such as global sourcing, quality-orientation, just-in-time practices. It is almost consensus that quality should be the selection driver, however, some polemical findings questioned this general agreement. Therefore, one of the objectives of the study was to identify the supplier selection criteria and bring this discussion back again. Moreover, Dickson (1966) suggested existing business relationship as selection criterion, then it was reviewed the importance of business relationship for the company and noted a set of potential negative effects that could rise from it. By considering these side effects of relationship, this research aimed to investigate how the relationship could influence the supplier selection and how its harmful effects could affect the selection process. The impact of this phenomenon was investigated cross-nationally. The research strategy adopted was a controlled experiment via vignette combined with discrete choice analysis. The data collections were performed in China and Brazil. By examining the results, it could be drawn five major findings. First, when purchasers were asked to declare their supplier selection priorities, quality was stated as the most important independently of country and relationship. This result was consistent with diverse studies since 60’s. However, when purchasers were exposed to a multi-criteria trade-off situation, their actual selection priorities deviate from what they had declared. In the actual decision-making without influence of buyer-supplier relationship, Brazilian purchasers focused on price and Chinese buyers prioritized delivery then price. This observation reinforced some controversial prior studies of Verma & Pullman (1998) and Hirakubo & Kublin (1998). Second, through the introduction of the buyer-supplier relationship (operationalized via relational capital) in the supplier selection process, this research extended the existing studies and found that Brazilian buyers still focused on price. The relationship became just another criterion for supplier selection such as quality and delivery. However, from the Chinese sample, the results suggested that quality was totally discarded and the decision was majorly made through price and relationship. The third finding suggested that relational capital could legitimate the quality and sustainability of the supplier and replaces these selection criteria and made the decisional task less complex. Additionally, with the relational capital, the decision-makings were associated to few biases such as availability cognition, commitment, confirmatory and perceived biases. By analyzing the purchasers’ behavior, relational capital inducted buyers of both countries to relax in their purchasing requirements (quality, delivery and sustainability) leading to potential negative effects. In the Brazilian sample, the phenomenon of willing to pay a higher price for a lower quality offer demonstrated to be a potential counterproductive and suboptimal decision. Finally, the last finding was associated to the cultural effect on the buyers’ decisions. From the outcome, it is possible to observe that if a purchaser’s cultural background is more relation-oriented, the more he will tend to use relational capital as a decision heuristic, thus, the purchaser will be more susceptible to the potential relationship’s side effects
