Diversas teorias tentam explicar o que determina a política de financiamento adotada pelas empresas. Uma das abordagens existentes, a Teoria de Pecking Order, foca a assimetria de informação como um importante determinante da estrutura de capital. No presente trabalho, busca-se analisar o pressuposto central da referida teoria e verificar se a assimetria de informação influencia nas decisões de financiamento de empresas brasileiras abertas no período 1997-2007. Para tanto, são utilizadas variáveis ...

Despite the growing interest in sustainable practices, many organisations in the agro-food industry are currently struggling to implement sustainable supply chain (SSC) innovations. This research addresses this gap by studying the Brazilian coffee industry, which is considered not only an important commodity for the Brazilian economy, but also for the global market. To achieve the goals of this study, a bibliometric assessment of the literature was carried out to understand the drivers and barriers ...

Several studies have emphasized the necessity of incorporating factors unrelated to the firm characteristics into their capital structure analysis. Rajan and Zingalas (1995) and Booth et al. (2001) argued for the importance of institutional factors which have remained unexplored and Faulkender and Petersen (2006) have looked at the role of access to the public debt market in the determination of the leverage level. This paper evaluates the impact of (1) specific sources of capital with differentiated ( ...

Tuberculosis (TB) rates among prisoners are more than 20 times that of the general population in Brazil, yet there are limited data available to facilitate the development of effective interventions in this high-transmission setting. We aimed to assess risk factors for TB infection and evaluate the yield of mass screening for active disease among inmates.

Abstract Background Brazil is one of the highest tuberculosis ( TB ) burden countries of the world. Cutaneous tuberculosis ( CTB ) is a rare form of extrapulmonary manifestation of tuberculosis. This study aimed to describe the clinico‐evolutive, laboratory and therapeutic aspects of CTB cases among patients from a cohort with TB in Rio de Janeiro, Brazil. Methods Cases of diagnosed CTB with microbiologic confirmation or clinical response to anti‐tuberculous treatment associated with positive smear or histopathological ...

This paper analyzes the occurrence of market timing and its effects on primary share issues (IPOs and SEOs) of 123 Brazilian firms in the 2004–2015 period, by investigating the relation between the cumulative abnormal returns and amount of proceeds raised. We use cumulative abnormal returns, before and after the share issue, as a proxy for equity market timing. The results indicate the existence of market timing in the decision to issue shares in the Brazilian capital market, reflected in the abnormal ...

The development of cancer immunotherapy has long been a challenge. Here, we report that prophylactic vaccination with a highly attenuated Trypanosoma cruzi strain expressing NY-ESO-1 (CL-14-NY-ESO-1) induces both effector memory and effector CD8+ T lymphocytes that efficiently prevent tumor development. However, the therapeutic effect of such a vaccine is limited. We also demonstrate that blockade of Cytotoxic T Lymphocyte Antigen 4 (CTLA-4) during vaccination enhances the frequency of NY-ESO-1-specific ...

The diagnosis of disseminated sporotrichosis is usually obtained by necropsy and the isolation of Sporothrix schenckii from blood is rare. Fungemia was shown in vivo through the isolation of S. schenckii from peripheral blood of 13 (n=38, 34.2%) cats with naturally acquired sporotrichosis. The coinfection with FIV and with FeLV found, respectively, in 6 (n=34, 17.6%) cases and 1 (n=34, 2.9%), apparently did not alter the frequency of the isolation of S. schenckii from peripheral blood.
