In the United States the number of births to unmarried mothers is at a record high. Although being unmarried is a significant risk factor for low birth weight and preterm births, paternal presence may have a protective effect. In addition to marital status, paternity may be a proxy measure for paternal support. Virginia birth registry data were analyzed to investigate the effect of marital and paternity status on low birth weight and preterm births. Findings from this study show that women who reported being unmarried and with no paternity status were 1.6 (odds ratio = 1.57, 95% confidence interval = 1.41–1.75) and 1.4 (odds ratio = 1.39, 95% confidence interval = 1.21–1.61) times more likely to have preterm low birth weight and term low birth weight babies, respectively. Being unmarried and lack of established paternity appear to be significantly correlated with and may be important risk factors for preterm and low birth weight deliveries. Health care professionals should be aware of the potential role of paternal presence and marital status may play with respect to preterm births and low birth weight. 相似文献

Professional encounters bestow moral esteem upon professional helpers while denigrating those who access services. Yet society is arranged in such a way that professional services are indispensable for many to survive, and service users can experience them as simultaneously helpful and oppressive. We explore the ambivalent figure of the professional “adversarial ally” working within these systems through accounts from two research studies that straddle or resist the common-sense line that separates care from harm. Professionals need to acknowledge how we are experienced as adversaries in order to better forge relationships of solidarity or “alliance” with those using social and medical services. 相似文献

A serious barrier to our understanding of urban ecosystems is a lack of information on the ecology of soils organisms of green spaces within large cities. This study addresses this gap by providing baseline survey data on the biodiversity of soil macrofauna in urban parks and domestic gardens of London, UK. In April and June 2004, the soil macrofauna were handsorted from soil cores in eleven parks and gardens of various sizes in central London. Five taxa were identified to species (Lumbricidae, Isopoda, Diplopoda, Chilopoda and Formicidae). The biodiversity value of the two main habitats (horticultural borders and mown grass lawns) was assessed and the influence of a range of environmental factors on species density (number of species per unit area) examined. The species densities of the studied soil invertebrates in the urban gardens were comparable with those found in natural ecosystems, although plant borders contained significantly more species than lawns. Borders had higher levels of plant nutrients, higher floristic diversity and lower levels of micronutrients and heavy metals than lawns. Significant predictor variables of species densities in the plant borders were the percentage of leaf litter cover, sampling month and soil pH. Species densities in the lawns were significantly correlated with the distance of the samples from the edge of the lawn. 相似文献

Retirement and Productive Activity in Later Life 总被引:2,自引:2,他引:0

It is commonly believed that as people age and leave the labor force, they disengage from productive activity and become dependent. While consistent with the conventional economic view of what constitutes productive activity, this belief is inconsistent with a more contemporary view that unpaid work (domestic, volunteer, and caring work) is equally economically valuable (i.e., productive). We investigate differences in how people allocate time among productive and other activities pre- and post-retirement. Results indicate that people remain engaged in productive activities even as they move out of the labor force, substituting unpaid for paid work. Only respondents who have exceeded their normal life expectancy greatly reduce their productive activity. Evidence suggests a need to revisit assumptions underlying policy debate on population aging.

Criticisms of the concept “organizational goal”are summarized. An alternative formulation is proposed wherein organizations are viewed as open systems. Through continual interaction incumbents seek to manipulate, and are manipulated by, expectations that they, and persons within various environmental sectors, hold for the organization regarding its mission, authority relations, relative status, affective expressions and sanctioning activity. Organizational missons include sets of social expectations which define appropriate tasks, priorities, territoralities, processing procedures and evaluation criteria. Behavioral observations of police communication officers are used to explore one aspect of mission—organizational priority. Three types of criteria appear critical in understanding priority rankings: 1) feedback intensity, 2) environmental capability to influence recognition and acceptance of feedback, and 3) sequential requirements. 相似文献
