In recent years, out migration from the Upper West Region to the southern belt of Ghana for farming has become commonplace. The natural question that has arisen is: what is the potential impact of remittances from this migration pattern on food security in the region? Using multivariate ordered logistic regression this study assesses the linkage between remittances and household food security (derived using the HFIAS) among urban and rural households (n=1,438) in the region. The findings show that urban remittance‐receiving households and rural remittance and non‐remittance receiving households were more likely (OR=2.44, p<0.05; OR=2.46, p<0.001; and OR=1.49, p<0.1, respectively) to report being more severely food‐insecure than urban non‐remittance receiving households. The findings demonstrate that household strategies such as migration and remittances on their own are not sufficient to ameliorate the precarious food insecurity situation of the region. The study calls for development of alternative livelihoods in the region.  相似文献

This study is the first to comprehensively examine the effect of state anti-bullying laws (ABLs) on school safety and youth violence. Using existing data from the Youth Risk Behavior Surveys and the Uniform Crime Reports, and newly-collected data on school shootings, we find little evidence that the typical state ABL is effective in improving school safety and student well-being. However, this null finding masks substantial policy heterogeneity. State mandates that require school districts to implement strong, comprehensive anti-bullying policies are associated with a 7 to 13 % reduction in school violence and an 8 to 12 % reduction in bullying. In addition, our results show that strong anti-bullying policy mandates are associated with a reduction in minor teen school shooting deaths and violent crime arrests, suggesting potentially important spillover effects.  相似文献

This study’s purpose was to develop a temporal and cultural definition of volunteering in China. Using a comparative mixed-methods approach, N1 = 218 Chinese students in Hong Kong were surveyed about their perceptions of volunteering. These quantitative data were compared cross-culturally with a sample of adults in the United States who used the same instrument called Who is a Volunteer? Subsequently, N2 = 40 of these same students voluntarily participated in a series of focus groups, to further explore more in-depth their opinions about volunteering. The main quantitative results revealed that at the extreme ends of the volunteer scale, both the U.S. and Chinese samples could readily distinguish what volunteering was or was not. The more nuanced empirical differences on the scale (24% of the 21 items) were explained either by unique cultural differences, or the longer and more prominent history that volunteering has had in North America versus China. Main qualitative findings revealed additional between-group cultural differences exemplified by (1) a more family-centric and collectivist Chinese culture versus a more individualistic American culture, (2) a role blurring about volunteer activities versus paid work activities, and (3) that both organizational and cultural context must be seriously considered when defining volunteerism. This study adds to the growing definitional literature on this transformational concept and represents the largest comparative empirical investigation on this subject from East Asia.  相似文献

We derive an empirical poverty index containing most of those proposed in the literature. Then, we study its asymptotic behavior by using empirical processes theory. From the results obtained, we derive a Wald-type test for comparing a vector of theoretical poverty indices to a vector of reference indices. We study the test statistic under the null hypothesis of equality, fixed alternatives, and a sequence of local alternatives. A simulation experiment conducted shows that our test performs well for exponential and Pareto data.  相似文献

Materialism and Quality of Life   总被引:1,自引:0,他引:1  
An attempt is made in this paper to establish a foundation for a theory of materialism and quality of life. The theory posits that overall life satisfaction (quality of life) is partly determined by satisfaction with standard of living. Satisfaction with standard of living, in turn, is determined by evaluations of one's actual standard of living compared to a set goal. Materialists experience greater dissatisfaction with their standard of living than nonmaterialists, which in turn spills over to overall life causing dissatisfaction with life in general. Materialists experience dissatisfaction with their standard of living because they set standard of living goals that are inflated and unrealistically high. These goals set by materialists are more influenced by affective-based expectations (such as ideal, deserved, and need-based expectations) than cognitive-based ones (such as predictive, past, and ability based expectations). Materialists' ideal standard-of-living expectations are influenced by social comparisons involving remote referents, more so than comparisons involving standards that are situationally imposed. Examples of situationally-imposed standards are perceptions of wealth, income, and material possessions of family, friends, neighbors, colleagues, and so on. In contrast, examples of standards based on remote sources are perceptions of standard of living of others in one's community, town, state, country, other countries; perceptions of standard of living of others based on gender, age, education, ethnicity, occupation, and social class. This tendency to use remote referents in social comparisons may account for materialists' inflated and value-laden expectations of their standard of living. Materialists' deserved standard-of-living expectations are influenced by the tendency to engage in equity comparisons involving income and work. Thus, materialists compare themselves with others that seem to have more income and worked no harder. These equity comparisons generate feelings of inequity, injustice, anger, or envy. These emotions may also account for materialists' inflated and value-laden expectations of their standard of living. Materialists' standard-of-living expectations based on minimum needs are influenced by the tendency to spend more than generate income. This proclivity to overconsume and underproduce may be partly responsible for materialists' inflated and value-laden expectations of their standard of living.  相似文献
