Two stylized facts about poverty in Africa motivate this article: female-headed households tend to be poorer, and poverty has been falling in the aggregate since the 1990s. These facts raise two questions. First, how have female-headed households fared? Second, what role have they played in Africa’s impressive recent aggregate growth and poverty reduction? Using data covering the entire region, we reexamine the current prevalence and characteristics of female-headed households and ask whether their prevalence has been rising, what factors have been associated with such changes since the mid-1990s, and whether poverty has fallen equiproportionately for male- and female-headed households. Lower female headship is associated with higher gross domestic product. However, other subtle transformations occurring across Africa—changes in marriage behavior, family formation, health, and education—are positively related to female headship, resulting in a growing share of female-headed households. This shift has been happening alongside declining aggregate poverty incidence. However, rather than being left behind, female-headed households have generally seen faster poverty reduction. As a whole, this group has contributed substantially to the reduction in poverty despite their smaller share in the population.  相似文献

We study a risk-sharing agreement where members exert a loss-mitigating action which decreases the amount of reimbursements to be paid in the pool. The action is costly and members tend to free-ride on it. An optimal risk-sharing agreement maximizes the expected utility of a representative member with respect to both the coverage and the (collective) action such that efficiency is restored. We study the sustainability of the optimal agreement as equilibrium in a repeated game with indefinite number of repetitions. When the optimal agreement is not enforceable, the equilibrium with free-riding emerges. We identify an interesting trade-off: welfare generated by the optimal risk-sharing agreement increases with the size of the pool, but at the same time the pool size must not be too large for collective choices to be self-enforcing. This generates a discontinuous effect of pool size on welfare.  相似文献

This article examines how the state has used its spending power to shape the nonprofit sector in British Columbia since the 1960s. The province's thriving nonprofit sector and its polarized political culture provide an ideal case study for exploring the relationship between the state and nongovernmental organizations. The following study documents changes in state policy, the trajectory of funding, funding patterns, and organizations that have received state funding. Although public funding for nonprofits in Canada has been pervasive for decades, there is little empirical evidence on the nature and scope of this funding. This article is based on an innovative new database that provides a comprehensive list of grants from the provincial government to nonprofit organizations between 1960 and 2014. Despite concerns regarding cuts to public funding in recent years, this study finds that there has been an overall increase in funding. However, there has also been a significant shift in funding from women's issues to Aboriginal peoples since the early 2000s.  相似文献

The development and validation of a patient exit interview tool, the Interprofessional Clinic Homeless Satisfaction with Student Engagement Survey (ICHSES), and its incorporation in the administration of an interprofessional, co-curricular program, the Community Homeless Interprofessional Program (CHIP) is described. Incorporation of patient satisfaction with student engagement during interprofessional training experiences serving individuals who are homeless has not been previously published. At CHIP, medical, pharmacy and social work students engage with individuals experiencing homelessness in a church and faculty-supervised environment. The students provide basic health assessment, education, and referrals to community resources. Once the interaction with the students is complete, patients are asked to participate in an exit-interview using the ICHSES. Questions in the ICHSES focus on engagement with the students and the patient’s perception of the assistance they received. Based on survey responses by 220 patients, the 5 question ICHSES showed high reliability (Cronbach’s alpha?=?0.77). The ICHSES survey could be utilized in similar clinics engaged in serving the homeless.  相似文献

The objective of the present study was to investigate the gambling behavior of individuals who frequent non-gambling video games arcades. One hundred and twenty two subjects (mean age of 19.2 years (SD=5.5); males constituted 82.8%) who spend time in arcades completed the South Oaks Gambling Screen and the Jacob's Health Survey. The results showed that 10.7% were identified as probable pathological gamblers and 14.8% were problem gamblers. The frequency of visits to arcades for non-gambling activities appeared to be correlated with the extent to which individuals gamble, and is furthermore associated with pathological gambling. The rate of pathological gamblers who frequent arcades is more than twice as high as the rates reported in other studies with adolescents and adults.This research was partially supported by grants from the Fonds Richelieu and Loto-Québec awarded to the first author.  相似文献

In this paper, we establish several connections of the Poisson weight function to overdispersion and underdispersion. Specifically, we establish that the logconvexity (logconcavity) of the mean weight function is a necessary and sufficient condition for overdispersion (underdispersion) when the Poisson weight function does not depend on the original Poisson parameter. We also discuss some properties of the weighted Poisson distributions (WPD). We then introduce a notion of pointwise duality between two WPDs and discuss some associated properties. Next, we present some illustrative examples and provide a discussion on various Poisson weight functions used in practice. Finally, some concluding remarks are made.  相似文献
