Abstract

While many studies have examined the separate effects of gender and marital status on patterns of perceived social support, none have examined the simultaneous effects of these two variables while controlling for other relevant variables in a large, random sample. This paper responds to this lacuna by investigating the relationships among these variables for six specific types of problems that may elicit social support from others. Using data drawn from a representative sample of the United States population, results indicate that the perception of sources of social support is primarily shaped by differences in marital status as opposed to gender. However, gender is influential in some situations. While it is not significantly related to the perception of emotional support, gender is significantly related to the perception of instrumental support. (Women manifest a tendency to consider both spouse / partner and relatives as sources of instrumental support more than men, while men rely on friends as sources of instrumental support.) The suggestion that gender may find expression within categories of marital status is supported by findings indicating that, within each of the marital status categories, when men turn to relatives and / or friends for help they tend to be male and when women turn to relatives and / or friends for help they tend to be female. Suggestions for future research are offered.  相似文献

Abstract

This study provides evidence to support the validity of the UK Health and Safety Executive Management Standards Indicator Tool, which is widely used in the UK by organizations to test for stress-related working conditions. A large pooled data set was collected from 137 UK organizations (N=67,347) to test the factor structure of both the original 35-item seven-factor instrument and a new shorter 25-item version. The results showed that the tool was a good fit to the data for both versions. Further analysis examined the factor structure of the Indicator Tool by splitting the data set into both public and private sector organizations. Tests for measurement invariance showed that both versions of the Indicator Tool provided a good fit to the data. The final sequence of analysis showed that the measurement structure of both the 25-item and 35-item scales was also invariant across small-, medium- and large-sized organizations. The current study provides percentile tables for both the public and private sectors so that organizations can compare their scores against UK national benchmarks. Overall, this study validates both the full and the short versions of a valuable and reliable diagnostic instrument for use in a variety of organizations.  相似文献

Two case studies illustrate multicriteria decision making techniques frequently used in procurement practice: least-cost sufficient performance and weighted utility optimization. Both techniques have defects and are rarely robust. Decision by exclusion and pairwise comparisons is proposed as a third approach which eliminates inferior alternatives by generalized forms of minimum performance requirements established under multicriteria framework. It is more robust and maintains high level of accountability.  相似文献

This study examines the number of placement moves experienced over an eight-year period by 5,557 children in one state who first entered out-of-home care between birth and age six. This group comprised 28% of all young children who entered care during this period. Nearly 30% of children in kinship care and 52% of children in nonrelative care experienced placement instability (defined as three or more moves after the first year in care). Children in kinship care, regardless of age, had fewer placement moves than those in nonkinship care. A multivariate analysis found that children who had more than one placement move during their first year of care were more likely to experience placement instability in long-term out-of-home care than if they did not move or were moved only once during their first year in care.  相似文献

This article argues that the changes characterized by many commentators as announcing the 'information age' are better seen, not as heralding a new type of society, but as the continuation, consolidation and extension of capitalism - something which is accompanied by constant upheaval and innovation. The shift from conceiving the 'information society' as a result of technological breakthroughs to one which lays emphasis on the primacy of 'information' itself is observed. The importance especially of informational labour's 'flexibility' is regarded, not as indicative of a new age but of the requirements of globalized capitalism which engenders change the better to consolidate its practices. The instability of life today is ascribed, not to the upheavals resulting from the 'information revolution', but rather to the insatiable dynamic that has long been a distinguishing feature of capitalist enterprise. These processes are examined in terms of the shift from public to private provision of information and in the heightened uncertainty of existence today.  相似文献

This article observes high levels of anxiety about war in the present era, although wars are in decline. It addresses this paradox by distinguishing ideal‐typical features of Industrial and Information War. Industrial War is fought predominantly between states over territory, harnesses industry and the military, and requires mass mobilisation of people as well as resources. Information War is the prerogative of a few advanced societies and has emerged in a context that has enabled the extension of market practices on a global scale (with America as a unipolar power). Information War transcends frontiers, is asymmetrical, and its hard side is manifest in digitalised technologies and small professional forces. However, its soft side evokes the expanded and fast‐changing information environment of globalised media, trans‐national networks and the Internet. Through these, media wars can be experienced intensely by civilians who are otherwise untouched: at once close up and far away. This contributes to heightened consciousness of war, although such spectators are removed from danger. Although interests try to control information flows from and about war, the information environment is huge, shifting and unpredictable. As such, it is impossible to control fully, thereby presenting opportunities for vigorous symbolic struggles involving anti‐war campaigners and others.  相似文献

A resolution of Sen's paretian liberal paradox is provided which does not require agents to waive their rights or have self-supporting preferences. The solution concept is an elaboration of a certain kind of path dependence, primary path construction.  相似文献
