A alavancagem financeira consiste na estratégia de aumentar a variação dos resultados em relação às receitas, devido às despesas financeiras advindas do uso de capital terceiros, como financiamento de investimentos. Contudo, nem sempre o adequado nível de endividamento de uma empresa é identificável claramente, e pode provocar uma alavancagem com perdas de resultados. Desse modo, este estudo objetivou verificar qual a influência da alavancagem financeira em relação à rentabilidade dos investidores nas empresas brasileiras. Adotaram-se métodos da estatística descritiva, com intuito de averiguar as correlações entre as variáveis estudadas: GAF e Endividamento; e GAF e ROE. Aplicou-se o teste t de Student para verificar se houve significância das médias das empresas que obtiveram GAF > 1 ou GAF ≤ 1. Os índices de correlação apresentaram-se de forma positiva, mostrando forte relação entre as variáveis. Concluiu-se que é significante o número de empresas que mantiveram sua situação favorável de alavancagem financeira com GAF > 1, tendo o retorno sobre o ativo superior à remuneração paga ao capital de terceiros, sempre atentas às proporções de capital de terceiros utilizados na composição da estrutura de capital. Financial leverage consists of the strategy of increasing the variation of the results in relation to the revenues, due to the financial expenses derived from the use of third capital, as investment financing. However, a company’s adequate level of indebtedness is not always clearly identifiable, and can lead to loss-of-profit leverage. Thus, this study aimed to verify the influence of financial leverage in relation to the profitability of investors in Brazilian companies. Descriptive statistics methods were used in order to ascertain the correlations between the studied variables: GAF and Indebtedness; and GAF and ROE. The Student’s t-test was applied to verify if there was a significance of the means of the companies that obtained GAF > 1 or GAF ≤ 1. The correlation indexes were positive, showing a strong relationship between the variables. It was concluded that the number of companies that maintained their favorable financial leverage situation with GAF > 1 was significant, with a return on the asset higher than the remuneration paid to the capital of third parties, always attentive to the proportions of third-party capital used in the composition of the capital structure.

This study aims to explore the association between nurses' leadership styles and personal and professional nursing profile and workload. The sample consisted of seven nurses and seven nursing technicians who were grouped into pairs. At the end of three months, nurses were queried regarding what leadership style would be adopted when the nursing technician under their evaluation delivered care to patients admitted to the ICU. Relevant data was analyzed by applying descriptive statistics, Tukey's multiple comparison test and Student's t-test (p< 0.05). Nursing workload reached 80.1% on average. The personal and professional profile variables did not show any relation with the leadership styles chosen by nurses (p>0.05). The determine, persuade, and share leadership styles prevailed. However, whenever the nursing workload peaked, the determine and persuade styles were used (p<0.05).

The relevance of the study of the parenthood perceptions of modern adolescents is determined by decreasing level of paternity readiness among modern youth. The aim of the study is to investigate the features of adolescents' parenthood apprehensions. The study involved 63 teenagers (37 boys and 26 girls) aged 15 to 17 years. Adolescents’ parenthood perceptions were studied with the help of «Ideas of Ideal parenthood» (R.Ovcharova, Yu.Degtyaryova), as well as with the method of «Composition about parenthood» (O.Karabanova, A.Shvedovskaya, modification by S.Abdullina). Such methods as the descriptive statistics, correlation analysis, Student’s t-test were used for data analyses. Parenthood perceptions are considered as an indicative basis for future parenthood readiness. The content and hierarchy of different components of these apprehensions are defined, such as: cognitive, emotional and behavioral. The content of adolescents' parenthood apprehensions were revealed, including the image of the future child, the image of relationships in the future family, the idea of himself/herself as a parent. In particular, adolescents’ perceptions about themselves as future parents were found to be the least represented in the descriptions of the subjects; they are often associated with ambivalent feelings. Significant differences in the content of adolescents’ parenthood apprehensions about ideal parenting were found. Their structure depends on gender: girls’ perceptions are wide enough and mostly they are positively emotionally colored, the majority of the boys’ perceptions are not formed and often they have neutral, negative or ambivalent emotional coloring. Gender differences in the structure and level of components of parenthood perceptions manifest themselves in the significantly higher level of girls’ behavioral and emotional components, as well as in the greater interconnection of the different components of boys’ parenthood perceptions.

Intravesical prostaglandin E2 is effective in the recovery of spontaneous voiding after transvaginal reconstruction of the pubocervical fascia and short arm sling according to Lahodny. The aim of the study was to compare the effects of intravesical prostaglandin E2 in the prevention of urinary retention after transvaginal reconstruction of the pubocervical fascia and short arm sling according to Lahodny. STUDY DESIGN: From November 1996 to June 1999 fifty women underwent the Lahodny procedure for moderate/severe cystocele and stress urinary incontinence. Women were randomly assigned to 1 of the 2 study groups: intravesical prostaglandin E2 versus controls. Data obtained were analyzed with the Student t test and the Fisher exact test. RESULTS: Two patients of the treatment group had to be excluded from the study, one because of the wrong measurement of the post-voidal residual volume and another due to a fastidious burning sensation which appeared immediately after prostaglandin instillation and required the suspension of the treatment. No other side effects such as nausea, vomiting, diarrhea or hyperthermia were observed. Patients who underwent the prostaglandin E2 treatment showed a recovery of spontaneous voiding after 7.9&plusmn;6.7 days, whereas this interval was significantly longer in the control group, being 12.9&plusmn;9.7 days (p=0.04, Two tailed Unpaired Student's T test). CONCLUSION: The effectiveness and the low associated morbidity mark the treatment with intravesical prostaglandin E2 useful in the recovery of normal voiding after transvaginal pubocervical fascia reconstruction and short arm sling with the procedure according to Lahodny.

Introduction: The changing proportion of older adults in society necessitates the need to determine the attitudes of health care professionals toward older adults. The purpose of this study was to explore attitudes of ageism and its correlates among health care professionals working with older adults. Method: This descriptive study was conducted in seven hospitals in five cities in Turkey. A total of 628 health care professionals participated in this study. The Fraboni Scale of Ageism (FSA) was used to collect data. Descriptive statistics, student’s t test, one-way analysis of variance and multivariate linear regression were used for data analysis. Results: The mean total score from the FSA was 56.9 ( SD = 8.0). Education (β = −.18, p < .001) and difficulty with the care of older adults (β = −.10, p < .05) were statistically significant predictors of the FSA score. Conclusions: The attitudes of health care professionals toward older adults were generally positive and affected by difficulty in providing care and the educational status of the health care professionals.

Functional and structural damages of tubulointerstitium are caused by proteinuria. The aim of this study was to assess the influence of different proteinuria levels on Na+, K+, Cl tubular transport. We examined 50 patients (24 males, 26 females), mean age 46.50 ? 13.08 years, with mean creati-nine clearence of 87.29 ? 31.17 mL/min. They were separated in three groups depending on proteinuria value. The first group with proteinuria less than 0.3 g/24h included 19 persons (7 males, 12 females), mean age 45.12 ? 13.28 years, with mean creatinine clearance of 94.27 ? 34.70 mL/min. The second group of 18 patients (8 males, 10 females), mean age 45.39 ? 12.64 years had proteinuria of 0.3-3,0 g/24h and mean creatinine clearance of 90.07 ? 31.89 mL/min. The third group had proteinuria level higher than 3.0g/24h and mean creatinine clearance of 73.25 ? 20.44 mL/min. It included 13 patients (9 males, 4 females), mean age 50.08 ? 13.73 years. As a parameter of proteinuria influence on tubular transport of Na+, K+ and Cl-, fractional excretion of these electrolytes, was studied. Student's T test, Mann Whitney U test and c2 test were used for statistical analysis. No statistically significant influence of proteinuria was found on Na+, K+ and Cl tubular transport.
