Abstract: castor bean (ricinus communis l.) is a very important crop in northeastern brazil. nowadays it became also important in other regions of brazil, due to the brazilian biodiesel program. the objective of the present work was to estimate general and specific combining ability for seed yield and agronomic traits in castor bean, in order to obtain a better understanding of the genetic control of these traits of breeding purposes. two groups of cultivars were studied: group 1, composed by five short stature cultivars, and group 2, composed by five tall cultivars. the two groups were crossed according to a partial diallel design, giving rise to 25 hybrid evaluated in a 5 x 5 lattice design with four replications. plots comprised of a nine meters single row spaced three meters apart (27 m2) with 10 plants. seed yield (pr), days to flowering (df), plant height (ap), height up to the primary raceme (ac), and length of primary raceme (tu) were evaluated. general combining ability (gca) was significant for all traits within each group, while specific combining ability (sca) was significant only for df and tu. the gca sum of squares was higher than sca sum of squares for all traits, indicating that additive effect loci were more important than dominant effect loci. in both groups there are cultivars with favorable alleles for yield and agronomic traits.

Abstract: Objective: The objective is to correlate the nursing diagnoses of the domain Safety/Protection of NANDA-I in critically ill patients with sociodemographic and clinical data. Method: A cross-sectional study with 86 individuals was conducted, from October 2013 to May 2014 in the Intensive Care Unit of a university hospital in northeastern Brazil, through a formal interview and physical examination. Results: It was possible to identify a total of 20 significant statistical associations, and 15 were clinically justified by the literature, namely: risk for aspiration and reason for admission; impaired dentition and age; risk for peripheral neurovascular dysfunction and sex and comorbidity; skin integrity and comorbidity; risk for impaired skin integrity and gender and reason for admission; impaired tissue integrity and gender and reason for admission; risk for perioperative positioning injury and reason for admission; risk for thermal injury and age and comorbidity; delayed surgical recovery and reason for admission; risk for poisoning and years of schooling; and risk for imbalanced body temperature and age. Conclusions: By understanding the relationship between customers’ answers and the sociodemographic and clinical profile, positive health outcomes can be achieved in particular in the prevention of risks facing vulnerability characteristics, providing greater safety and protection for the critical customer.

Abstract: the study of bank profitability involves two lines of discussion: (1) bank performance is important to guarantee the strength of the institution and the stability of the banking industry; and (2) a greater profitability might indicate that banks have an opportunistic behavior, associated to a concentrated market. this study is aimed at evaluating the degree of concentration of the brazilian banking industry and verifying whether there is a relationship between the level of bank profitability and the sector's degree of concentration, based on total assets, credit operations and bank deposits from january 2000 to december 2009. taking the parameters of brazilian antitrust authorities as benchmarks, we cannot find evidence of concentration in the brazilian banking industry, although it should be mentioned that the concentration indicator has increased substantially from the end of 2008 onwards. when we take the concentration parameters used in the us, we find that, by the end of the period, the indicators fall within the "moderate concentration" range. as a second aim of the paper, we test hypotheses based on the structure - performance paradigm, which assumes that less competition associated to higher concentration results in higher bank profitability. the results do not corroborate the hypotheses in any of the combined tests performed, because the parameters are either statistically insignificant or negative. expectations that higher market concentration would explain higher bank profitability, according to the structure - performance hypothesis, are not confirmed. on the contrary, we find evidence that the efficient structure hypothesis explains the profitability of the brazilian banking industry more adequately.
Testando a teoria de hierarquiza??o de fontes de financiamento nas empresas brasileiras
Medeiros, Otávio Ribeiro de;Daher, Cecílio Elias;
Revista Contabilidade & Finan?as , 2005, DOI: 10.1590/S1519-70772005000100003
Abstract: the paper tests if the theory known as pecking order theory provides empirical explanations for the capital structure of brazilian firms. according to this theory, the capital structures would result from a hierarchy of financial decisions, in which internally generated resources would have first priority, followed by debt issues and, as a last resort only, by equity issues. in its strong form, the pecking order sustains that equity issues would never occur, whereas in its weak form, limited amounts of issues are acceptable. the methodology adopted in this empirical study involves cross-sectional regressions and the testing of hypotheses based on the underlying theory in its strong and weak forms. the results led to the conclusion that the tested theory, in its weak form, is applicable to brazilian firms, but that the same does not happen in its strong form. the results also show that the goodness of fit of the brazilian regressions are significantly better than those reported for american firms and that brazilian firms seem to be closer to the pecking order's strong form than the american ones. the sample involves 132 publicly listed firms and the accounting data refer to 2001.
Emiss?es públicas de a??es, volatilidade e insider information na Bovespa
Medeiros, Otávio Ribeiro de;Matsumoto, Alberto Shigueru;
Revista Contabilidade & Finan?as , 2006, DOI: 10.1590/S1519-70772006000100003
Abstract: the paper uses an event study to examine stock returns associated to public equity issues carried out by brazilian firms listed on bovespa, from 1992 to 2002, with the purpose of determining how the market reacted before, during, and after the issue announcement dates. after utilizing the conventional method for measuring abnormal returns by ols, we used arch and garch models, which take into account the conditional heteroskedastic volatility of the abnormal returns in more than 70% of the sample, since the presence of these processes was found in the original residuals. the results show that (1) there is evidence of insider information prior to the announcement date, (2) abnormal returns occurred on the announcement date, and (3) within one year after the issues, the shares of issuing firms had negative returns after adjusting for risk and market effects.

Medeiros, Otávio Ribeiro de;Daher, Cecílio Elias;
Revista de Administra??o Contemporanea , 2008, DOI: 10.1590/S1415-65552008000100009
Abstract: the paper documents results of empírical tests involving two models applied to the capital structure of brasilian firms. the models tested were developed under the two theories competing for the determination of the capital structure of firms in the academic literature: the static tradeoff theory and the pecking order theory. the methodology involves the utilization of panel-data econometric techniques, aiming to establish which of the two theories has higher explanatory power for the brazilian firms. the analisis utilized three types of models: common coeficients, fixed effects, and random effects. additional statistical tests were also employed to confirm the robustness of results. the sample consists of non-financial firms listed in the sao paulo stock exchanges (bovespa and soma) from 1995 to 2002. the analysis of the results obtained led to the conclusion that the pecking order theory in its semi-strong form provides the best explanation for the capital structure of brazilian firms.
