人—工作匹配对员工工作幸福感的作用机制研究

基于社会交换理论,通过对209名员工2个时点的配对问卷调查,探讨了人—工作匹配和工作幸福感的关系及其作用机制,尤其是工作卷入的中介作用和工作技能的调节作用。结果发现:人—工作匹配对工作幸福感具有显著的正向作用;工作卷入在人—工作匹配和工作幸福感之间起部分中介作用;工作技能在人—工作匹配和工作卷入之间起调节作用,即工作技能水平越高,人—工作匹配对工作卷入的正向影响越强。     

Constructing poverty in anti-welfare Singapore

In recent years, attention on the issue of poverty in Singapore has been increasingly placed in the spotlight. This study examines the various types of attitudes among Singaporeans and how they are formed, relating them to the broader institutional context of Singapore. A mixed method design is employed where clusters or groups of attitudes are derived through the use of cluster analysis. Subsequently, discourses of poverty and welfare attitudes are construed through qualitative interviews with the aid of Foucauldian Discourse Analysis. Quantitative findings point to three clusters of attitudes: ‘Conservatives’, ‘Liberals’, and ‘Sui Generis’. Qualitative findings, however, show that ‘Sui Generis’ ultimately align themselves closer to either ‘Conservatives’ or ‘Liberals’ in their discourses of welfare. In fact, respondents in all three clusters reproduce state discourses, albeit in varying ways. In essence, this study explicates poverty and welfare attitudes as a product of social identities premised on subjective notions that are shaped by state discourses of meritocracy, self-reliance and anti-welfarism. It is thus argued that current socio-political constructions of poverty ensue a paucity of major welfare reform in the near future of Singapore.     

Permutation tests of scale using deviances

Robust tests for comparing scale parameters, based on deviances—absolute deviations from the median—are examined. Higgins (2004) proposed a permutation test for comparing two treatments based on the ratio of deviances, but the performance of this procedure has not been investigated. A simulation study examines the performance of Higgins’ test relative to other tests of scale utilizing deviances that have been shown in the literature to have good properties. An extension of Higgins’ procedure to three or more treatments is proposed, and a second simulation study compares its performance to other omnibus tests for comparing scale. While no procedure emerged as a preferred choice in every scenario, Higgins’ tests are found to perform well overall with respect to Type I error rate and power.     

Religion in the Lives of Older Women Serving Life in Prison

This exploratory qualitative study examined the roles of religiousness in the lives of 21 older women (mean age = 63) serving life sentences in one southern state. Based on survey and focus group methodology, several themes emerged as important focal points, including early religious experiences prior to incarceration, imprisonment and religious doubt, participation in formal and informal religious activities, and use of religion in coping with stressors such as interpersonal relationships, trauma, and health statuses. Irrespective of their religious upbringing, all participants agreed that religiosity/spirituality played a key role in their ability to cope with their prison experience as well as for maintaining hope and the opportunity for release.     

QUANTIFYING THE LIFE CYCLE OF SCHOLARLY ARTICLES ACROSS FIELDS OF ECONOMIC RESEARCH

Does the life cycle of economic papers differ across fields of economic research? By constructing and analyzing a large dataset that combines information on 9,672 articles published in the top five economic journals from 1970 to 2000 with detailed yearly citation data obtained from Google Scholar, we find that published articles do have a life cycle that differs across fields of economic research (which we divide into the categories of applied, applied theory, econometric methods, and theory). Applied and applied theory papers are the clear winners in terms of citation counts. For the first years after their publication, they receive higher numbers of citations per year than papers in other fields of research do. They also reach a higher peak number of citations per year and apparently sustain those peak levels for longer, in addition to being cited over longer periods of time (i.e., they have a longer lifespan). Citation patterns are much less favorable for theoretical papers, which are the object of fewer citations per annum in the first years following publication, have lower peak numbers and a shorter lifespan. Econometric method papers are a special case; the pattern for most of these papers is similar to the pattern for theory papers, but the most successful papers (as measured by the number of citations) on econometric methods are also the most successful papers in the entire discipline of economics.

Multinomial Selection in the Presence of Infinite Alternatives

We propose a new procedure for the multinomial selection problem to solve a real problem of any modern Air Force: the elaboration of better air-to-air tactics for Beyond Visual Range air-to-air combat that maximize its aircraft survival probability H(θ, ω), as well as enemy aircraft downing probability G(θ, ω). In this study, using a low-resolution simulator with generic parameters for the aircraft and missiles, we could increase an average success rate of 16.69% and 16.23% for H(θ, ω) and G(θ, ω), respectively, to an average success rate of 76.85% and 79.30%. We can assure with low probability of being wrong that the selected tactic has greater probability of yielding greater success rates in both H(θ, ω) and G(θ, ω) than any simulated tactic.

Contents of heavy metals in arable soils and birth defect risks in Shanxi, China: a small area level geographic study

The burgeoning demands of China’s urbanization and industrial development put pressure on the resources of the entire country and have direct and indirect effects on the health of individuals, at times in areas far removed from cities themselves. Current evidence suggests that heavy metal pollution in soil, a common by-product of coal mining and other industrial activities, may be linked to risk of birth defects. We examine this hypothesis using small area level data including soil samples and detailed birth records from 2002 to 2004 from 97 villages in Shanxi province, a heavy coal-mining region. We find that soils containing arsenic, lead, and nickel are significantly correlated with the incidence of birth defects. In particular, we find a strong positive dose-dependent association of birth defects with lead, a moderate positive effect with arsenic, and a dose-dependent negative association with nickel. These results are consistent with the postulated link between arsenic and lead and human birth defects, but raise questions about the effects of nickel in this context. China’s rapid urbanization underscores the need for closer attention to the relationship between the health and the environment.     

基于国内外发展经验的CBD构建方式探讨

CBD是城市的经济发展中枢.它标志着一个城市的现代化程度,是现代城市的亮丽名片.建立CBD是建立现代化大都市的需要,有利于培育新的经济增长点.CBD的形成是经济社会发展水平的必然产物,CBD的功能演进与空间演变都是动态的发展过程.CBD建设结构比例不合理会导致其功能失衡,综合开发是增强CBD生命力的重要手段.当今时代,CBD的开发方向应当朝着市场化、多元化、信息化、国际化、多功能的方向发展.     

Anatomy of a Municipal Triumph: New York City's Upsurge in Life Expectancy

Over the period 1990–2010, the increase in life expectancy for males in New York City was 6.0 years greater than for males in the United States. The female relative gain was 3.9 years. Male relative gains were larger because of extremely rapid reductions in mortality from HIV/AIDS and homicide, declines that reflect effective municipal policies and programs. Declines in drug‐ and alcohol‐related deaths also played a significant role in New York City's advance, but every major cause of death contributed to its relative improvement. By 2010, New York City had a life expectancy that was 1.9 years greater than that of the US. This difference is attributable to the high representation of immigrants in New York's population. Immigrants to New York City, and to the United States, have life expectancies that are among the highest in the world. The fact that 38 percent of New York's population consists of immigrants, compared to only 14 percent in the United States, accounts for New York's exceptional standing in life expectancy in 2010. In fact, US‐born New Yorkers have a life expectancy below that of the United States itself.
