Perceived Determinants of Well-Being and Enjoyment Level of Leisure Activities

Two facets of leisure, perceived determinants of well-being and enjoyment of common leisure activities, were investigated in 388 participants. For well-being, a principal components (PCA) analysis yielded five components: competence, relatedness and health, wealth, personal values, and freedom of choice. For the enjoyment of leisure activities, another PCA generated seven components: wellness, sedentary leisure, intellectual leisure, social leisure, routine activities, self-realization, and inner peace. Different leisure enjoyment of young adults (18–30 years old) in contrast to adults and seniors was attributed to social transformations as also predicted by several theories of social change. The relationship between the determinants of well-being and enjoyment of leisure activities was statistically significant but meaningfully debatable.

Chasing Success: Health Sector Aid and Mortality

As many cases studies show, successful public health measures are being implemented in many places around the globe, and country-level mortality has fallen significantly in recent decades in all but a few countries. Are the two linked? Does development assistance for health (DAH) improve, on balance, recipient countries’ mortality trajectory? Using a new data source containing DAH on 96 high mortality countries, the regression analysis shows no effect of DAH on mortality. Other types of aid, including water development, also have no effect. Economic growth, on the other hand, has a strong negative effect on mortality. These findings confirm and build upon recent work by Williamson (2008) and are shown to be robust to a variety of sensitivity analyses and alternative model specifications and estimation methods.This analysis also shows that the effectiveness of DAH has not increased over time, even as the level of that funding has increased fourfold, though spending on infectious diseases and family planning may have caused small reductions in mortality. Furthermore, even though it is encouraging that DAH has tended to go where the need is highest, it also goes to states that have experienced the greatest mortality reductions in the recent past. In other words, DAH appears to be following success, rather than causing it.

配电网无功补偿分组容量

直流输电的运行方式多,功率调节快速、平稳,因此直流传输功率变化很大,通常在额定直流输送容量的10%～110%范围内变动。为适应直流功率的变化,同时满足换流站交流母线电压变化的需要,无功补偿装置必须实行分组投切。     

网络环境对我国高校图书馆的影响

随着信息技术和网络技术的不断发展,信息社会已经到来,网络正在深刻的影响着人们的工作、学习和生活方式。网络环境同时对各个行业都产生了深远的影响,图书馆作为国家信息资源保障中心,受网络环境影响的表现则更为直接和具体。特别是对高校图书馆来说,由于其服务对象、信息资源建设的特殊性等原因,就更加需要重视网络环境带来的巨大影响力,积极应对信息浪潮带来的巨大变革,从而提出工作建设的新思路。     

PREMATURE MORTALITY AND POVERTY MEASUREMENT

There is a glaring paradox in all commonly used measures of poverty. The death of a poor person, because of poverty, reduces poverty according to these measures. This surely violates our basic intuitions of how poverty measures should behave. It cannot be right in concept that differentially higher mortality among the poor serves to reduce poverty. This article begins the task of developing poverty measures that are not perversely mortality sensitive. A family of measures is proposed that is an intuitive modification of standard poverty measures to take into account the fact that the rich live longer than the poor.
