This article draws upon findings from the New York Services Study, a Federally-funded qualitative study conducted in practice settings representing two fundamentally different approaches to serving homeless adults with serious mental illness and co-occurring substance abuse. The findings yielded four themes??cumulative adversity, individual acts of kindness in a system designed to control, discordant case managers?? perspectives, and the benefits of permanent housing. Recommendations for practice include respecting individuality, being sensitive to previous traumas, and working to achieve housing security sooner rather than later. Future research is needed to study the micro-level contexts of service delivery and how they inhibit or encourage engagement in care.  相似文献

An increase in both illegitimate births and in the number of single women retaining their offspring has become evident in all Commonwealth industrialized English-speaking countries. It is shown that women who bear ex-nuptial children are getting younger, and that about 40 per cent are keeping their children. All States show a gradual increase in ex-nuptial births, with those in Western Australia and Queensland rising to over 10 per cent of annual live births for the areas. Further research is needed on single women in Australia who keep their children.  相似文献

Multipartnered fertility (“MPF”) has become a major topic of interest in the United States due to potential negative linkages with parental, child, and family wellbeing. A first step in studying any newly emerging (or newly identified) social phenomenon is to properly define the issue and identify its prevalence. However, this is problematic in the case of MPF because most existing sources of data were not originally designed to study MPF. We examine the major data sources used to produce estimates of MPF in the United States, discussing the methodological issues that produce conflicting prevalence estimates and providing guidelines for producing comparable estimates. We also discuss important considerations for research seeking to link MPF and outcomes. Our recommendations will help researchers situate their findings in the broader literature and spur future research.  相似文献

Christchurch urban lawns are dominated by non-native grasses and forbs. However, we document considerable plant diversity; the total number of species encountered in our 327 sampled lawns was 127, although 80 species occurred in <2% of lawns. Seven distinct lawn communities were identified by Two-Way INdicator SPecies ANalysis using occurrence of 47 species that occurred in > 2% of lawns. Our ability to explain variation in species composition was surprisingly good and indicates intensity of lawn maintenance such as frequency of mowing, irrigation, fertiliser, and herbicide use and whether clippings are removed or not plays the major role. Species richness significantly declines with an increase in total area of contiguous lawn, leaf litter cover, the presence of grass clippings, and on loamy soil. Hence, park lawns with coarser management had lower species richness than residential lawns. Native species were more prevalent in well tended residential lawns, where more frequent mowing and removal of clippings or litter build-up diminishes shoot competition or shading. There is tremendous potential for more native species in New Zealand lawns which would contribute substantially to the conservation of endangered lowland herbaceous flora.  相似文献

Investigating the possibilities of change in marital relationships, we argue, involves examining the interplay of gender consciousness, relational resources and material circumstances in their concrete, interactional manifestations. The attempt to address this interface is grounded in the idea that understanding gender relations necessarily involves both institutional and interactional dimensions. While much research has been devoted to the influence of material or structural resources on indicators such as the domestic division of labour, relatively little direct attention has been given to the issue of differing ‘relational’ or interpersonal resources. We use a multi-method approach based on interviews with women in different occupations to analyse possibilities of change in marital communication and the domestic division of labour in relation both to women's material and to their relational resources. We conclude that a combination of increased gender consciousness and the development of particular inter-personal skills facilitates negotiation and change in the boundaries regulating both communication and the domestic division of labour within the marital relationship.  相似文献

This paper examines the relationship between risk perceptions, affect and the economic consequences of a bio-security threat against the U.S. food system. The main argument is that there exists a link between risk perceptions and economic behavior. The paper raises conjectures through a utility-theoretic economic model and examines these through two separate surveys, the first being a hypothetical agroterrorist attack and the second a hypothetical discovery of ‘bird flu’ in the United States. The results provide strong evidence that risk perception and fear can interact with consumption in an economically significant way.  相似文献

The National Center for Health Statistics (NCHS) reports life expectancy at birth (LE) for each year in the United States. Censal year estimates of LE use complete life tables. From 1900 through 1947, LEs for intercensal years were interpolated from decennial life tables and annual crude death rates. Since 1948, estimates have been computed from annual life tables. A substantial drop in variation in LE occurred in the 1940s. To evaluate these methods and examine variation without artifacts of different methods, we estimated a consistent series of both annual abridged life tables and LEs from official NCHS age-specific death rates and also LEs using the interpolation method for 1900-1998. Interpolated LEs are several times as variable as life table estimates, about 2 times as variable before 1940 and about 6.5 times as variable after 1950. Estimates of LE from annual life tables are better measures than those based on the mixed methods detailed in NCHS reports. Estimates from life tables show that the impact of the 1918 influenza pandemic on LE was much smaller than indicated by official statistics. We conclude that NCHS should report official estimates of intercensal LE for 1900-1948 computed from life tables in place of the existing LEs that were computed by interpolation.  相似文献

Drug-related violence is now an everyday occurrence in Mexico's northern border-states. While it often appears that all crimes are on the rise in the border region, the actual number of alleged offenders caught and brought to court differs significantly for different types of crime. Using panel data for Mexico's 31 states plus the Federal District from 2004 to 2008, it was found that there were more alleged offenders caught per 100,000 inhabitants involving theft, property damage, and carrying prohibited arms, in Mexico's northern border-states compared to interior states. The effects of other socioeconomic variables on crime in Mexico, such as GDP, incarceration rates, births to single mothers and expenditures on public security, were also examined.  相似文献
