Acerca da família nuclear

Este trabalho é motivado por uma questão básica, presente, atual: A família nuclear estaria sofrendo uma transformação em sua organização. Especificamente a dissolubilidade dos laços matrimoniais estaria contribuindo para uma diferente ordenação das relações de parentesco. O modelo familiar proposto, aqui no Brasil, pela Igreja e pela higiene, como procuramos demonstrar no texto, está, ao menos no que diz respeito à classe média da população, sendo descaracterizado por um tipo de relacionamento afetivo diverso do casamento tradicional "até que a morte os separe". Esta pergunta se amplia numa questão maior: ou a organização familiar transforma-se através da história, através das diferentes formações sociais, ou a família nuclear, objeto da nossa pesquisa, é um sempre-existente; ou seja, desde que o homem se aculturou a forma de organização familiar se restringiu, com variações que não passariam de meras exceções, meros desvios da estrutura primordial (a família restrita), como querem alguns autores? A nossa resposta a esta questão é claramente a favor do ponto de vista que afirma a transformação da organização familiar através dos tempos, portanto através da história, e o que é mais importante, através de diferentes formações sociais. Assim sendo, fomos levados, não só pela nossa prática, mas principalmente pela íntima ligação que a pesquisa histórica revela entre o surgimento da psicanálise e a sedimentação do modelo da família restrita, pelo novo poder de "gerir a vida", ou seja, um poder que, ao invés de tirar a vida daqueles que não o servem a contento, se interessa em extrair da vida tudo que de melhor ela pode dar, um poder a quem interessa uma qualidade cada vez maior de corpos, a fim de explorar a maior quantidade possível de produção. A família por si só é um problema. Trata-se de uma instituição que obriga a todas as ciências humanas, inclusive a medicina, a se depararem com ela em suas respectivas práticas, seja esta prática empírica ou teórica. Daí, por tratar-se de um trabalho teórico, tornou-se necessário percorrer vários saberes, os mais notáveis no nosso entender, para poder atingir os nossos objetivos.

Factors affecting the technical efficiency of production of the Brazilian banking system : a comparison of four statistical models in the context of data envelopment analysis

This paper uses an output oriented Data Envelopment Analysis (DEA) measure of technical efficiency to assess the technical efficiencies of the Brazilian banking system. Four approaches to estimation are compared in order to assess the significance of factors affecting inefficiency. These are nonparametric Analysis of Covariance, maximum likelihood using a family of exponential distributions, maximum likelihood using a family of truncated normal distributions, and the normal Tobit model. The sole focus of the paper is on a combined measure of output and the data analyzed refers to the year 2001. The factors of interest in the analysis and likely to affect efficiency are bank nature (multiple and commercial), bank type (credit, business, bursary and retail), bank size (large, medium, small and micro), bank control (private and public), bank origin (domestic and foreign), and non-performing loans. The latter is a measure of bank risk. All quantitative variables, including non-performing loans, are measured on a per employee basis. The best fits to the data are provided by the exponential family and the nonparametric Analysis of Covariance. The significance of a factor however varies according to the model fit although it can be said that there is some agreements between the best models. A highly significant association in all models fitted is observed only for nonperforming loans. The nonparametric Analysis of Covariance is more consistent with the inefficiency median responses observed for the qualitative factors. The findings of the analysis reinforce the significant association of the level of bank inefficiency, measured by DEA residuals, with the risk of bank failure.

Does mixed frequency vector error correction model add relevant information to exchange misalignment calculus? Evidence for United States

Real exchange rate is an important macroeconomic price in the economy and a ects economic activity, interest rates, domestic prices, trade and investiments ows among other variables. Methodologies have been developed in empirical exchange rate misalignment studies to evaluate whether a real e ective exchange is overvalued or undervalued. There is a vast body of literature on the determinants of long-term real exchange rates and on empirical strategies to implement the equilibrium norms obtained from theoretical models. This study seeks to contribute to this literature by showing that it is possible to calculate the misalignment from a mixed ointegrated vector error correction framework. An empirical exercise using United States' real exchange rate data is performed. The results suggest that the model with mixed frequency data is preferred to the models with same frequency variables

An analysis of the perceived service quality of hospitality industry in Rio de Janeiro through the SERVQUAL model: a multiple case study

Brazil is under political and financial crises where the end seems far away. Because of that, researchers argue that the hotel rooms offered by Rio de Janeiro, built to host the Olympic Games 2016, will be difficult to occupy after the event. It is then necessary for the hotels to understand how guests perceive the service quality in order to adapt to this new era. If guests’ perceptions meet or exceed their expectations, they will be satisfied and will probably return. Thus based on the SERVQUAL approach, this paper aims to study the impact of the service dimensions on the guests’ overall satisfaction at hotels of Rio de Janeiro. Two hotels were considered representative of the city in terms of service quality and customers’ profile. Interviews to the hotel managers were performed, and questionnaires to the guests were administered. Among the five SERVQUAL dimensions – Reliability, Tangibles, Responsiveness, Assurance, and Empathy – the Empathy dimension appears to be the only one that affects the guests’ overall satisfaction. The study could also identify that gender, country of residence, home country and family income have an impact on guests’ satisfaction. This study has no intention of generalization, but rather of refining the theory about services and the SERVQUAL model.
