Linda G. Martin 《Demography》1989,26(4):627-643
Using logit techniques and data from surveys of the elderly conducted in 1984 under the auspices of the World Health Organization, this article investigates socioeconomic, cultural, and demographic determinants of living arrangements of the elderly. Having a spouse or children with whom to live has important effects on living arrangements. The results provide only weak support, however, for hypotheses based on modernization theory and point to the need for detailed data on transitions in living arrangements and for information about the younger generation as well as the older generation, both of which are involved in deciding who lives with whom.  相似文献

The aim of the current study was to examine the interactive effects of depressive symptoms and lower extremity functioning on social participation for a group of moderately to severely disabled older women. The study used a cross-sectional community based sample, enrolled in the Women’s Health and Aging Study I, randomly selected from the Centers for Medicare & Medicaid Services enrollment files for women living in the Baltimore, Maryland area. The participants were women aged 65 or older who completed the in-person interview (n = 999). After adjusting for demographics and risk factors, each unit increase in the Short Physical Performance Battery (SPPB) score was associated with a 0.31 point increase in satisfaction with social participation for the non-depressed group, and 2.04 points for the depressed group. Depressive symptoms and lower extremity functioning interact to affect satisfaction with social participation. Among women with high depressive symptoms the gradient of association with social participation increased sharply with better lower extremity function compared with non-depressed women, where the gradient of association was moderate. The findings suggest the potential value of programs that focus on improving lower extremity function among older high risk groups.  相似文献

Normative, Gain and Hedonic Goal Frames Guiding Environmental Behavior   总被引:2,自引:0,他引:2  
This article discusses new developments about goal-dependent framing and multiple goal frames (sometimes also called "multiple motives"), which are highly relevant for understanding environmental behavior. We introduce goal-framing theory, which postulates that goals "frame" the way people process information and act upon it. Three goal frames are distinguished: a hedonic, gain, and normative goal frame. In general, multiple goals are active at any given time, which may (or may not) be compatible; that is, the strength of the focal goal may be influenced by other goals that are in the background. Based on an extensive review of studies in environmental psychology, we suggest those conditions under which each goal frame may be dominant in influencing environmental behavior. In the environmental context, normative goal frames imply acting pro-environmentally, while gain and hedonic goal frames often result in not acting in an environmentally sound manner. Next, we argue that pro-environmental behavior may be promoted by strengthening normative goals or by making gain and hedonic goals less incompatible with normative goals. Finally, based on goal-framing theory, we suggest questions to be addressed in future research.  相似文献

This article discusses key issues related to current reproductive technologies including contextual and personal barriers to use, complexity of decision making, limited access to technologies for poor women and women of color, and the politics and social controversy surrounding this area. New reproductive technologies have to be put to the same test as any other product--can and will women use them correctly? We need to not only know about the technology itself; we also need to know about the individuals who intend to use the technology and about contextual factors that influence use. Accordingly, the articles in this issue focus on the multiple determinants that influence acceptability of reproductive technologies and the policy, political, and legal implications associated with their use.  相似文献

This paper examines the extent to which developmental idealism has been disseminated in Malawi. Developmental idealism is a set of beliefs and values about development and the relationships between development and family structures and behavior. Developmental idealism states that attributes of societies and families defined as modern are better than attributes defined as traditional, that modern societies help produce modern families, that modern families facilitate the achievement of modern societies, and that the future will bring family change in the direction of modernity. Previous research has demonstrated that knowledge of developmental idealism is widespread in many places around the world, but provides little systematic data about it in sub-Saharan Africa or how knowledge of it is associated with certain demographic characteristics in that region. In this paper, we address this issue by examining whether ordinary people in two settings in Malawi, a sub-Saharan African country, have received and understood messages that are intended to associate development with certain types of family forms and family behaviors. We then examine associations between demographic characteristics and developmental idealism to investigate possible mechanisms linking global discourse about development to the grassroots. We analyze data collected in face-to-face surveys from two samples of Malawian men in 2009 and 2010, one rural, the other in a low-to-medium income neighborhood of a city. Our analysis of these survey data shows considerable evidence that many developmental idealism beliefs have been spread in that country and that education has positive effects on beliefs in the association between development and family attributes. We also find higher levels of developmental idealism awareness in the urban sample than we do in the rural sample, but once dissimilarities in education and wealth between the two samples are controlled, awareness levels no longer differed between urban and rural respondents. We explore how these beliefs intersect with longstanding local values and beliefs in Malawi.  相似文献

Politics in the workplace is a reality of organizational life. Several studies have investigated the negative implications of perceived organizational politics on various work attitudes and performance measures but not on proactive performance. However, proactive performance is important in a sales context because salespeople operate in an uncertain environment, and some task aspects cannot be formalized. Moreover, there is still a need for research to analyse the psychological mechanisms that lead perceived organizational politics to cause negative reactions from employees as well as to provide new insights on the boundary conditions of this process. Therefore, we examine the effect of perceived organizational politics on proactive performance through a salesperson's trust in the sales manager, as well as the moderating role of the salesperson's experience.This study uses dyadic data from 192 salespeople and their sales managers from a range of industries. The model entails a moderated mediation process. Results support the proposed model. The findings contribute to the salesforce management literature by suggesting the need to consider the importance of perceived organizational politics and by aiding in the understanding of how and when it hinders proactive performance.  相似文献

In this paper, we call attention of two observed features in practical applications of the Generalized Autoregressive Moving Average (GARMA) model due to the structure of its linear predictor. One is the multicollinearity which may lead to a non-convergence of the maximum likelihood, using iteratively reweighted least squares, and the inflation of the estimator's variance. The second is that the inclusion of the same lagged observations into the autoregressive and moving average components confounds the interpretation of the parameters. A modified model, GAR-M, is presented to reduce the multicollinearity and to improve the interpretation of the parameters. The expectation and variance under stationarity conditions are presented for the identity and logarithm link function. In a general sense, simulation studies show that the maximum likelihood estimators based on the GARMA and GAR-M models are equivalent but the GAR-M estimators presented a little lower standard errors and some restrictions in the parametric space are imposed to guarantee the stationarity of the process. Also, a real data analysis illustrates the GAR-M fit for daily hospitalization rates of elderly people due to respiratory diseases from October 2012 to April 2015 in São Paulo city, Brazil.  相似文献

This paper proposes a methodology for measuring Quality of Employment (QoE) deprivation from a multidimensional perspective in six Central American countries (Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, and Panama) using a dataset specifically designed to measure employment conditions. Building on previous work on multidimensional poverty and employment indicators, the paper uses the Alkire/Foster (AF) method to construct a synthetic indicator of the QoE at an individual level. It selects four dimensions that must be considered as essential to QoE deprivation: income, job stability, job security and employment conditions. These dimensions then subdivide into several indicators, a threshold for each indicator and dimension is established before defining an overall cut-off line that allows for the calculation of composite levels of deprivation. The results generated by this indicator show that Central American countries can be divided into three distinct and robust performance groups in terms of their QoE deprivation. Overall, approximately 60% of the deprivation levels are attributable to non-income variables, such as occupational status and job tenure. The methodology used can allow policymakers to identify and focus on the most vulnerable workers in a labour market and highlights the fact that having a formal written contract is no guarantee of good job quality, particularly in the case of women.
