The authors have developed and tested scale-up methods, based on a simple social network theory, to estimate the size of hard-to-count subpopulations. The authors asked a nationally representative sample of respondents how many people they knew in a list of 32 subpopulations, including 29 subpopulations of known size and 3 of unknown size. Using these responses, the authors produced an effectively unbiased maximum likelihood estimate of the number of people each respondent knows. These estimates were then used to back-estimate the size of the three populations of unknown size. Maximum likelihood values and 95% confidence intervals are found for seroprevalence, 800,000 +/- 43,000; for homeless, 526,000 +/- 35,000; and for women raped in the last 12 months, 194,000 +/- 21,000. The estimate for seroprevalence agrees strikingly with medical estimates, the homeless estimate is well within the published estimates, and the authors' estimate lies in the middle of the published range for rape victims.  相似文献

Stockholder and stakeholder perspectives have been positioned in the literature as being in tension, and thus a potential source of innovation and change. However, researchers have overlooked a systematic examination of this presumption in theory and in practice. This study explores the ways that stockholder and stakeholder assumptions are presented by theorists and compares these with expressions of stockholder and stakeholder perspectives used by firms in practice. We argue that theoretical entrenchment dichotomizing these perspectives has disrupted the ability of researchers to leverage this tension. While scholarship remains trapped in a vicious cycle, we also argue that firms in practice express only the acceptance dimension of a virtuous cycle. Our empirical research demonstrates that firms accept and accommodate the paradoxical tension between managing for stockholders versus balancing the interests of stakeholders. This is evidenced by strategies we identify as book‐ending, cadence, continuous and simultaneous co‐mingling, and hybridization. We find that in practice these tensions are more integrated whereas in theory they are treated as more distinct and, often, in conflict. We suggest ways in which both scholarship and practice can better leverage tension as paradoxical opportunity.  相似文献

The current paper explores recent changes in food insecurity among adolescents and determine if food security concerns are associated with poorer wellbeing. Data were collected as part of two nationally representative surveys of the health and wellbeing of high-school students in New Zealand in 2007 and 2012. In 2012, 11% of young people reported food security concerns often or always, with 33% reporting food security concerns occasionally/sometimes. The prevalence of food security concerns at both frequencies increased significantly from 2007 (8% and 28%, respectively). Young people with food security concerns were more likely to report poor indicators of health and wellbeing, including truancy, poor general health, mental health concerns and obesity. Our findings highlight the growing concerns of food insecurity reported by adolescents in New Zealand. Interventions that address food security for families may provide a tangible means of promoting the healthy development of children and young people.  相似文献

This case study presents details of the life of one older man who lived in seclusion and squalor, surrounded by hoarded possessions. This man was one participant of a focused ethnography of eight older adults who received home care. All participants in the original ethnography were identified by their community care coordinators as exhibiting hoarding behaviors. The case study presented here provides rich narrative and photographic detail in order to add strength to what has already been presented in previous research articles about compulsive acquisition. The narratives reveal examples of debilitating dysfunction, distress associated with decision making, broad acquisition of free things, compulsive buying, and ritualistic discarding. Quotes included in the case study stem from the original ethnography.  相似文献

ABSTRACT

To prepare students to work competently with financially at-risk individuals, families, and communities, social work schools need to bring economic literacy skills into the curriculum. This article describes an ambitious financial capability education initiative in New York City. It reports on a unique collaborative effort to develop, use, and evaluate online financial capability education among seven schools. Additionally, readiness and capacity for scaling up with upstate schools are explored, as their innovations in economic capacity building with special populations are cited.  相似文献

Individually, both near-misses and losses disguised as wins (LDWs) have been seen to exert pro-motivational effects on gambling. However, it is not clear whether both structural characteristics are effective within the same game. Participants (n = 40) played a slot machine simulation. The simulation delivered near-misses, wins and ‘full-misses’. Half the participants also received LDWs that occurred independently of the outcomes on the payline. Valence and motivation ratings were collected after each round. Results showed that the LDW group reported increased valence ratings compared to the no-LDW group. Within the LDW group, trials with LDWs also resulted in increased enjoyment compared to trials without LDWs. We distinguished near-misses falling either side of the payline. Near-misses before the payline (NMB) were rated as more motivational than near-misses after the payline (NMA), whereas NMAs were rated as more aversive than NMBs. These differences between the two near-miss types were exacerbated by LDWs. Results demonstrate LDWs increase the trial-by-trial enjoyment of non-win outcomes. The motivational and hedonic effects of near-misses differed for events either side of the payline, and these differences were exaggerated by the presence of LDWs. Thus, near-misses can retain their effectiveness in complex forms of gambling that also deliver LDWs.  相似文献

ABSTRACT

Although binge drinking is a prevalent and often problematic behavior among college students, there has been relatively little sociological research on this phenomenon. This study evaluates the applicability of social learning theory (Akers 1985 Akers , Ronald L. 1985 . Deviant Behavior: A Social Learning Approach . 3rd ed. Belmont , CA : Wadsworth . [Google Scholar] 2000 — . 2000 . Criminological Theories: Introduction, Evaluation, and Application , 3rd ed. Los Angeles : Roxbury . [Google Scholar]) to the binge drinking of a sample of approximately 1,500 students enrolled at four institutions of higher education. The social learning model explains approximately 45% of the variance in the binge drinking of these students. The results indicate that differential peer associations are by far the best predictor of this behavior. Other significant predictors include the definitions that students hold about binge drinking as well as their perceptions of the direct effects of alcohol consumption. These social learning variables also mediate the effects of demographic variables (i.e., gender, race, fraternity/sorority membership) on binge drinking. The results are discussed with respect to programs designed to prevent binge drinking. Possible directions for future research in this area are also suggested.  相似文献

Single motherhood in sub-Saharan Africa has received surprisingly little attention, although it is widespread and has critical implications for children’s well-being. Using survival analysis techniques, we estimate the probability of becoming a single mother over women’s life course and investigate the relationship between single motherhood and child mortality in 11 countries in sub-Saharan Africa. Although a mere 5 % of women in Ethiopia have a premarital birth, one in three women in Liberia will become mothers before first marriage. Compared with children whose parents were married, children born to never-married single mothers were significantly more likely to die before age 5 in six countries (odds ratios range from 1.36 in Nigeria to 2.61 in Zimbabwe). In addition, up to 50 % of women will become single mothers as a consequence of divorce or widowhood. In nine countries, having a formerly married mother was associated with a significantly higher risk of dying (odds ratios range from 1.29 in Zambia to 1.75 in Kenya) relative to having married parents. Children of divorced women typically had the poorest outcomes. These results highlight the vulnerability of children with single mothers and suggest that policies aimed at supporting single mothers could help to further reduce child mortality in sub-Saharan Africa.  相似文献
