Social capital depicts the extent of mutual trust in a jurisdiction. This study examines the impact of organizational social capital (OSC) on nonprofit (NP) density. Prior studies have argued that OSC positively impacts the community and the organization itself. These studies are either theory- based or survey based. Few available empirical studies also do not examine the OSC of all the counties of the United States. This study overcomes these limitations and finds from the US county-level empirical study that social capital advanced in membership organizations is positively associated with the growth of NP density. 相似文献

Public political participation is an exhaustive subject in the democratic system that is contributing as a tilled land since the birth of democracy. It has a wide range of frequency, but voting is one of the easiest among all forms of public participation. Despite the easiness of voting, Pakistan ranks 164th in terms of voter turnout among 169 countries of the world. The voter turnout of the second largest Muslim democracy and the fifth largest among all the democratic states was recorded as 45.3% in the 2013 general election, which was less than India’s (59.4%) and even Bangladesh’s (58.2%). More than half of the population in Pakistan does not think it is its duty to cast its vote. The present study is an effort to investigate public political participation through six independent variables: democratic political party, party mobilization, security, accessibility, leadership image and moderating factor citizen distrust, and a useful sample size of 1884 was collected across the country. SPSS version 24.0 was used to measure the data. The results show significant and positive relations among the dependent and independent variables, while citizen distrust negatively moderates the dependent and independent variables of the study. 相似文献

Transport infrastructure consumes a large fraction of the development assistance envelope. Yet procedures for evaluating transport infrastructure projects are typically ad-hoc. This paper proposes an approach to assess the differential impacts of alternative investment proposals in data constrained environments where conducting reliable impact analyses is difficult. We first demonstrate a technique for estimating the cost of transporting products to markets. We then estimate the impact of improving the road network on economic activity. Finally, we perform simulations to demonstrate a methodology for prioritising alternative investments. The analysis demonstrates a pragmatic, though rigorous, approach for assessing transport infrastructure benefits. 相似文献

Obesity and high body fat percentages are a major public health issue. The percentage of obese and overweight Americans has increased over the past 30 years. On average, overweight individuals with higher percent body fat than normal weight individuals are at increased risk for numerous negative outcomes both physically and mentally. A prime time to investigate changes in body composition and associated psychological influences on decision making is during the emerging adulthood period. The first few years of college are a time when adolescents begin to regulate for themselves their own eating behaviors. Previous research shows that freshmen gain weight and increase in percent body fat during their first year of college. The current study addresses the limitations of previous research by investigating (1) individual growth in percent body fat over a longer period of time in college than previous available research and (2) important psychological and sex differences in this growth. This study measures percent body fat across the first 3 years of college at 8 time points for 542 undergraduates (351 females, 65 %; 191 males, 35 %). Longitudinal data analysis was conducted to identify changes in percent body fat, psychological predictors of those changes, and how changes differ for males and females. Our study found that significant increases exist in percent body fat during undergraduates' college years and that change differs for males and females. In addition, through the use of nested hierarchical models, eating regulation style (autonomous or controlled regulation), appearance schema (self-evaluative salience or motivational salience), and body satisfaction were identified as influential predictors of change in percent body fat. For example, young females, who do not feel in control of their physical appearance yet spend a great deal of time maintaining their appearance, have the highest initial body fat percentage and the steepest increase in percent body fat. Overall, males and females with high autonomous regulation and high motivational salience are likely to maintain (instead of increase) percent body fat over the college years. Knowing the influence of these predictors can be useful for promoting health and intervening with young adults in the college setting and other emerging adults who are not enrolled in postsecondary institutions. 相似文献

This article examines the political economy of U.S. federalhighway demonstration grant allocations. Demonstration grantsare a rapidly growing segment of federal highway grants directlyearmarked for a congressional district by Congress, unlike themajority of highway grants where Congress determines a formulaand allocates funds accordingly to states. Our empirical analysis,considering the period 1983–2003, suggests that a state'sability to attract demonstration project grants is positivelyinfluenced by its contributions to the highway trust fund andpolitical variables, and it is not affected by the formula highwayaid and vehicle miles traveled in a state. 相似文献
