This study aimed to develop a social cohesion index for understanding the social relation between residents in high-rise group housing complexes through a self-reported questionnaire. As a background of the study, literature on social cohesion and related literature on residents’ social relation in high-rise housing were reviewed. Later, we selected different high-rise group housings of Kolkata, a city in the eastern region of India. We conducted few focus group surveys involving the residents of those high-rises and also conducted expert opinion surveys to identify a context-specific list of statements for evaluating residential social cohesion. Finally, based on the responses of interviews from 652 residents of the identified high-rise housings from the same city, followed by confirmatory factor analyses, three factors of residential social cohesion were identified with adequate reliability and validity. This index holds huge potential to explore residential social relation in high-rise housing and carry out empirical studies, across various disciplines, in other cities in the country and outside the country of similar socio-economic and cultural context.  相似文献

A key concern about population aging is the decline in the size of the economically active population. Working longer is a potential remedy. However, little is known about the length of working life and how it relates to macroeconomic conditions. We use the U.S. Health and Retirement Study for 1992–2011 and multistate life tables to analyze working life expectancy at age 50 and study the impact of the Great Recession in 2007–2009. Despite declines of one to two years following the recession, in 2008–2011, American men aged 50 still spent 13 years, or two-fifths of their remaining life, working; American women of the same age spent 11 years, or one-third of their remaining life, in employment. Although educational differences in working life expectancy have been stable since the mid-1990s, racial differences started changing after the onset of the Great Recession. Our results show that although Americans generally work longer than people in other countries, considerable subpopulation heterogeneity exists. We also find that the time trends are fluctuating, which may prove troublesome as the population ages. Policies targeting the weakest performing groups may be needed to increase the total population trends.  相似文献

Objectives: Male sex work (i.e., escorting) is a stigmatized profession, and men in the sex industry may hide their involvement to avoid negative social consequences. There is limited research comparing men who are out about being an escort to their friends and/or family to those who are out to neither friends nor family. Methods: Data were taken from a 2013 online study of male escorts who were categorized into 3 groups based on outness patterns — friends only (48.9%, n = 193), friends and family (26.6%, n = 105), or neither friends nor family (23.5%, n = 93) — and they were compared on demographic and behavioral variables. Results: We hypothesized that men out to neither friends nor family would perform poorer across indicators of health and well-being due to the lack of social support that can come from friends and family. However, with the exception of reporting lower satisfaction and pay from their last male client, this hypothesis was unsupported. Outness patterns were largely unassociated with social and sexual behaviors with the last male client, and the majority eschewed condomless anal sex with their last male client, suggesting escorts — regardless of how out they are to friends and family — could navigate safer-sex behaviors with their clients. Outness was associated with substance use (<12 months) and substance use with their last male client — men out to friends and family were, for the most part, the most likely to have used substances. Men out to friends and family were significantly more likely than others to have been escorting for more than 5 years and to be escorting full-time. Conclusions: Interventions for escorts that address substance use and sexual risk behaviors and incorporate supportive friend and family social networks may be an important area for future research.  相似文献

L'article pose la question d'une nouvelle inflexion rhétorique dans les régimes de mobilisation et de sélection de la main-d'oeuvre avec le recours systématique à la notion de «motivation» qui semble franchir un palier supplémentaire par rapport aux paradigmes précédents de qualification et de compétence en s'affranchissant totalement de l'idée de «capacités à tenir un poste de travail». Ce changement de paradigme sera interrogé à partir de l'analyse des critères de recrutement utilisés par les entreprises de travail temporaire qui constituent un observatoire privilégié des mutations contemporaines dans les relations d'emploi. Les entreprises de travail temporaire jouent sur le marché du travail un rôle de médiation à l'embauche de plus en plus important, par le biais en particulier d'une externalisation de la gestion des ressources humaines en plein développement. Elles contribuent ce faisant de manière tout aussi conséquente à définir et diffuser des nouvelles normes d’«employabilité».  相似文献

Stochastic frontier models are widely used to measure, e.g., technical efficiencies of firms. The classical stochastic frontier model often suffers from the empirical artefact that the residuals of the production function may have a positive skewness, whereas a negative one is expected under the model, which leads to estimated full efficiencies of all firms. We propose a new approach to the problem by generalizing the distribution used for the inefficiency variable. This generalized stochastic frontier model allows the sample data to have the wrong skewness while estimating well-defined and nondegenerate efficiency measures. We discuss the statistical properties of the model, and we discuss a test for the symmetry of the error term (no inefficiency). We provide a simulation study to show that our model delivers estimators of efficiency with smaller bias than those of the classical model even if the population skewness has the correct sign. Finally, we apply the model to data of the U.S. textile industry for 1958–2005 and show that for a number of years our model suggests technical efficiencies well below the frontier while the classical one estimates no inefficiency in those years.  相似文献
