People living in some arrangements show better health than persons in other living arrangements. Recent prospective studies document higher mortality among persons living in particular types of households. We extend this research by examining the influence of household structure on health using longitudinal data. We theorize that individuals experience role-based household relations as sets of resources and demands. In certain household structures, individuals are more likely to perceive that the demands made on them outweigh the resources available to them. This perceived imbalance poses a risk to individual health. We test our expectations by analyzing the relationship between living arrangements and health using data from waves 1 and 2 of the Health and Retirement Study. We focus on persons ages 51-61 and explore gender differences. We find prospective links between household structure and self-rated health, mobility limitation, and depressive symptoms. Married couples living alone or with children only are the most advantaged; single women living with children appear disadvantaged on all health outcomes. Men and women in other household types are disadvantaged on some health outcomes. Our results suggest that the social context formed by the household may be important to the social etiology of health. In addition, they qualify the well-known link between marital status and health: The effect of marital status on health depends on household context. 相似文献
Against the backdrop of discussions about the 'Information Society', the 'Informational Economy' and the role of IT in realizing organizational change we examine how representations of 'organizational knowledge' are constructed and used in work settings. We do this through the explication of ethnographic materials that detail the realization and use of Management Information (MI) in a major UK retail bank undergoing massive organizational change. We focus in particular on explicating how existing metric information was drawn upon to construct a representation of the work of the bank for those involved in managing that work. Systems designers have been increasingly interested in offering ways of conceptualizing the problem of 'knowledge' with a view to embedding these properties in systems. In the quest to develop representations of procedural knowledge to support work we argue that it is first necessary to understand how representations are actually created and used in work to support existing work practices. 相似文献
Literature on ambidexterity emphasizes the need for both exploration and exploitation. Large firms usually choose to implement structural ambidexterity to separate both activities. We here focus on an extreme case of such structural partitioning implemented as a secret skunkworks project in a large French automotive company. A qualitative survey using both primary and secondary data shows that the major basic and initial characteristics of a skunkworks (i.e. secrecy, urgency, and autonomy) created favorable conditions for the technological exploration. However, exploitation failed due to precisely those same characteristics coupled with the fact that the project did not respond to a specific market demand: The skunkworks suffered from what we call the "Robinson Crusoe effect." We therefore contribute to the literature on skunkworks, which have remained understudied in the academic literature, as well as on ambidexterity, by showing how the interrelation between different factors is crucial for structural ambidexterity to be successful 相似文献
Has civil society declined in the United States in the past 20 years? Multiple indicators suggest evidence for decline. This paper questions Robert Putnam's generational explanation for decline and suggests an alternative explanation, namely the structural economic transformation of the U.S. and how it has been managed. Individuals' perceptions of economic distress have increased since 1972 and are related to changes in indicators of civil society, including associational memberships, trust, anomia, and espoused racial and gay tolerance. Economic distress is also related to political interest and participation. Other consequences of an eroding civil society are discussed, including rising crime and inhibited economic productivity
What is the case for and how would one begin to construct a sociology of impairment? This paper argues that the realignment of the disability/impairment distinction is vital for the identity politics of the disability movement. The body is at the heart of contemporary political and theoretical debate, yet the social model of disability makes it an exile. The transformation of the body from a reactionary to an emancipatory concept implies a sociology of impairment. This paper explores the contribution that post-structuralism and phenomenology might make to this end. 相似文献
The goal of this study was to examine lifetime patterns of sexual assault and associated risks among a purposive sample of gay and bisexual men (N = 183; 18 to 35 years old, M = 24.3). Cross-sectional data were collected via written, self-administered questionnaires and face-to-face, event-based qualitative interviews. Alcohol severity scores indicated high rates of hazardous drinking (53.0%) and possible dependence (14.2%) among participants. One-half of men (50.8%) reported childhood sexual abuse (CSA), and 67.2% reported adult sexual assault (ASA). Average age at most recent ASA was 21 years. Most perpetrators (83.9%) of recent ASA incidents were male; 67.0% of participants reported consuming alcohol and/or drugs prior to the most recent incident. Regression findings indicated more severe CSA experiences and past alcohol-related problems predicted recent severe ASA. Although we found similarities between gay and bisexual men in lifetime sexual assault history, we found some distinct differences in ASA risk factors. Bisexual men reported higher alcohol severity scores, more female ASA perpetrators, higher internalized homophobia scores, and fewer male sexual partners than gay men. Findings suggest the need for interventions that reduce ASA risk among sexual minority men—and the potential benefits of focusing on alcohol consumption in risk reduction efforts. 相似文献
This article considers short memory characteristics in a long memory process. We derive new asymptotic results for the sample autocorrelation difference ratios. We used these results to develop a new portmanteau test that determines if short memory parameters are statistically significant. In simulations, the new test can detect short memory components more often than the Ljung-Box test when these short memory components are in fact within a long memory process. Interestingly, our test finds short memory autocorrelations in U.S. inflation rate data, whereas the Ljung-Box test fails to find these autocorrelations. Modeling these short memory autocorrelations of the inflation rate data leads to improved model accuracy and more precise prediction. 相似文献
