This longitudinal field study examined the determinants of integrative, volunteer community leadership. Using a sample of 1443 participants in 43 community leadership programs across North America, we linked altruistic, social- and self-oriented motives to the breadth of individuals' volunteer involvement in their communities. Individuals who engaged in volunteer community leadership reported more altruistic motives (i.e., they volunteered because they were concerned about others). High levels of voluntary community leadership were also associated with social motives, such as getting involved in the community because friends or important others think doing so is important. Regardless of their motives, participants engaged in their communities in new ways following participation in a community leadership program, suggesting that such programs foster integrative community leadership. Programs that focused on team building as part of their curriculum were the most successful in fostering new community leadership activities, and programs that focused on knowledge and awareness of the community were effective in increasing participants' knowledge and awareness of the community. Considered as a whole, results of this study suggest that community leadership programs can increase both knowledge and awareness of the community and actual engagement in the community for community members who choose to participate in such programs. 相似文献

Our study examines residential variability in the prevalence of cohabiting households, the extent to which children are present, characteristics of the household head, and multiple indicators of economic well-being. Despite a lower prevalence of cohabiting households in nonmetropolitan compared to other areas, a larger proportion contain children. For all measures considered, economic well-being is lowest for cohabiting households with children in nonmetropolitan areas, and compared to their metro counterparts a larger proportion receive all forms of public assistance. The higher likelihood of poverty among nonmetropolitan cohabiting households with children is not explained by the characteristics of the household heads in multivariate models predicting household poverty. Cohabitation clearly has different family and economic implications in nonmetropolitan than in other residential areas. 相似文献

Prospective associations of mothers’ parenting processes, youth disclosure, and youth problem behavior were examined in a longitudinal design following 244 adolescent sibling dyads over a 3‐year period. For both siblings, authoritative parenting was positively associated with youth disclosure and was negatively related to problem behavior, and coercive parenting was negatively associated with youth disclosure and was positively related to problem behavior. When the influence of older sibling problem behavior on younger sibling problem behavior was modeled, younger sibling disclosure accounted for the relationship of maternal parenting processes to problem behavior. Findings indicate the important role of sibling influence in the development of problem behavior, contextualizing the relative roles of maternal parenting and youth disclosure in the transmission of risk. 相似文献

The variance of the sampling distribution of the sample mean is derived for two sampling designs in which a single cluster is randomly drawn from an autocorrelated population. The derivations are motivated by potential applications to statistical quality control, where a "one-cluster" sampling design may often be used because of ease of implementation, and where it is likely that process output is autocorrelated Scenarios in statistical process control for which either non-overlapping or overlapping clusters are appropriate are described The sampling design variance under non-overlapping clusters is related to the sampling design variance under overlapping clusters through the use of a circular population. 相似文献

Comprehensive medical and mental health evaluations of children in foster care are recommended within 30 days of entering care. What constitutes a comprehensive evaluation has yet to be established. This study examines the need to include educational assessment as a component of the comprehensive evaluation. Rates of achievement and language problems for Arkansas school-age children are compared with rates of medical and psychiatric disorders to assess the relative need for including educational assessment. 相似文献

Staff in the health care industry experience workplace aggression at a much higher rate than the general workforce. However, a large proportion of aggressive incidents go unreported, and the source of many of these incidents is patients. This study investigates aggressive incidents from patients against certified nursing assistants (CNAs; n = 76) in a sample of six geriatric care facilities. The results indicate that CNAs experienced a median of 26 aggressive incidents over the course of the 2-week study and that approximately 95% of these incidents were not reported to the facility. The present study also empirically examines reasons why nursing staff decide to report incidents. Finally, this study reveals that the experience of aggression from patients is related to subsequent organizational commitment, job satisfaction, and intent to leave the job. 相似文献

Accumulation of deicing salts in soils in an urban environment 总被引:4,自引:1,他引:3

Examining rates of deicing salt accumulation and leaching in urban soils is important for understanding the distribution and
movement of salt in the environment. We examined autumn concentrations of deicing salts in soils in a moderately dense urban
landscape in eastern New York State. The study area contrasted to the isolated, rural highways examined in previous studies.
While NaCl was the most abundantly applied salt, Mg2+ (apparently from MgCl2, a secondary deicing salt) was the most abundant salt cation in soils. Moderate Na+ levels, and equivalent concentrations at depth and in surface samples, indicate that leaching of Na+ is rapid in this system. Leaching may ameliorate toxicity for land plants but accelerate inputs to aquatic systems. In contrast
to rural highway studies, where salt levels declined rapidly with distance to pavement, Na+ remained elevated at the maximum distance measured. Airborne salt dispersal and dense networks of pavement likely contribute
to widespread elevated salt levels. This semi-urban setting had salt levels high enough to be toxic to terrestrial plants
and soil protozoa. Even moderate levels of development can have dramatic effects on salt inputs into soils and aquatic systems.
