Although many studies have linked sleep problems with symptoms of psychopathology, fewer studies have examined the relationship
between sleep and dimensions of psychological health as well as depression. To fill this gap, 502 community residents were
surveyed about sleep habits, symptoms of anxiety and depression, as well as Ryff’s six dimensions of psychological well-being.
Using cut-offs suggested by epidemiological research, participants were classified as either optimal sleepers (those reporting
an average of 6 hours or less than 8.5 hours per night) or suboptimal sleepers (those sleeping less than 6 hours or 8.5 or
more hours per night). After controlling for demographic differences (i.e., sex, age, education, ethnicity, employment status,
marital status, presence of children), the Multivariate Analysis of Covariance (MANCOVA) suggested that optimal sleepers reported
fewer symptoms of depression, and anxiety, and reported higher levels of environmental mastery, personal growth, positive
relations with others, purpose in life, and self acceptance. Differences between optimal sleepers and non-optimal sleepers
in depressive symptoms, positive relations with others, purpose in life and self-acceptance remained significant when people
with mild to moderate symptoms of depression were eliminated from the data set. These results are consistent with a theoretical
framework that defines sleep as a resource related to stress management and self-regulation. 相似文献

In this article, we describe a general framework for the analysis of correlated event histories, with an application to a study of partnership transitions and fertility among a cohort of British women. Using a multilevel, multistate competing-risks model, we examine the relationship between prior fertility outcomes (the presence and characteristics of children and current pregnancy) and the dissolution of marital and cohabiting unions and movements from cohabitation to marriage. Using a simultaneous-equations model, we model these partnership transitions jointly with fertility, allowing for correlation between the unobserved woman-level characteristics that affect each process. The analysis is based on the partnership and birth histories that were collected for the 1958 birth cohort (National Child Development Study) aged 16-42. The findings indicate that preschool children have a stabilizing effect on their parents 'partnership, whether married or cohabiting, but the effect is weaker for older children. There is also evidence that although pregnancy precipitates marriage among cohabitors, the odds of marriage decline to prepregnancy levels following a birth. 相似文献

The study of character is a legitimate and essential topic for the analysis of leadership in organizations. We undertake three key objectives in this article to stimulate meaningful dialogue. First, a brief historical overview of the extant body of literature on character is provided. Second, working definitions of character and character-based leadership are introduced. Third, new directions for organizational scholars interested in examining the role of character-based leadership in both their research and teaching domains are suggested. 相似文献

Rapid Hispanic population growth represents a pronounced demographic transformation in many nonmetropolitan counties, particularly since 1990. Its considerable public policy implications stem largely from high proportions of new foreign‐born residents. Despite the pressing need for information on new immigrants in nonmetro counties and a bourgeoning scholarship on new rural destinations, few quantitative analyses have measured systematically the social and economic well‐being of Latino immigrants. This study analyzes the importance of place for economic well‐being, an important public policy issue related to rural Hispanic population growth. We consider four measures of economic mobility: full‐time, year‐round employment; home ownership; poverty status; and income exceeding the median national income. We conduct this analysis for 2000 and 2006–2007 to capture two salient periods of nonmetro Hispanic population growth, using a typology that distinguishes among nonmetropolitan areas by the categories of “traditional” immigrant destinations concentrated in the Southwest and Northwest, “new” immigrant destinations to capture recent and rapid Hispanic population growth in the Midwest and Southeast, and “all other” rural destinations as a reference category representing more typical nonmetro population trends. We also compare our results to those for metropolitan destinations. We find that place type matters little for stable employment but more so for wealth accumulation and income security and mobility. Compared with urban Latino immigrants, rural Latino immigrants exhibit higher rates of homeownership as well as greater likelihoods of falling into poverty and lower likelihoods of earning a measure of U.S. median income. From 2000 to 2006–2007, rural‐urban differences deteriorated slightly in favor of urban areas. We conclude by discussing implications of these findings and those of addressing rural immigrant economic well‐being more generally. 相似文献

Agreement on water and a watered-down agreement: The political ecology of contested coastal development in Down East, North Carolina 总被引:1,自引:0,他引:1
In 2006, land use planning emerged as a contested issue in the rural area known as ‘Down East’, Carteret County, in eastern North Carolina, USA. Down East is experiencing a transition from a commercial fishing to an amenity economy and concerns about related changes led to the formation of ‘Down East Tomorrow’ (DET), a grassroots group that proposed a one-year development moratorium in order to facilitate a community planning process. In this paper, we use political ecology to examine the fate of the moratorium as reflected in the public written record, primarily minutes of meetings of the Carteret County Board of Commissioners. We illustrate how issues of community, science, and governance were linked to an increasing focus on coastal water quality in the debate, and argue that this focus facilitated a switch by the Board from considering a development moratorium to adopting a conservation ordinance, one that fell short of addressing DET’s concerns. This outcome illustrates the power of formal political institutions in ’First World’ environmental conflicts and the difficulties of reconciling competing values associated with land use in areas of transition, especially where historical resistance to planning has been the norm. 相似文献

Both a resource-based view and transaction cost economics perspective point to firms deciding to either make-or-buy an input. In practice, this tends to result in low-skill functions being outsourced while those of higher value are retained. In this article, we explore a situation counter to the prevailing literature. We study a highly creative industry – fashion – and discover the relationship between core competence and outsourcing is not as simple as previously conceptualised. Creativity, fashion's assumed competency, rather than being guarded within a firm is instead often outsourced or borrowed. More mundane tasks such as marketing and logistics are what each firm rather develops. The effects of resulting co-dependencies are mapped and analysed in order to offer managerial insight as well as contribute to discussion within the outsourcing and resource based literatures. 相似文献
