中国城市化对GDP影响研究

随着中国经济的发展，中国的城市化规模日益扩展，进程不断深入，但对GDP增长的积极影响不明显。为此，一是要积极提高全民族的文化水平，特别是对要继续提高受高等教育人口在总人口中的比重，使之与城市化水平高的发达国家相接轨；二是要在产业规模方面，除了要积极发展第三产业之外，应该特别注意调整地区之间的产业结构，减少重复建设，真正实现区域之间的优势互补，相互促进；三是要注意防止过多的人口成为大城市发展的负担。     

通用桥式起重机主梁自重对拱度的影响及修正

通用桥式起重机主梁上拱度是起重机的重要技术指标,因此生产检测中所测的拱度值必须保证是准确可靠的。而在进行起重机桥架结构时,由于各种条件的限制,支架位置常常处于0.8倍跨度处,此时主梁自重对主梁拱度产生的影响值会有偏差,造成测得的主梁上拱度值是不准确的,因此需要对该值进行修正。通过生产实践总结和理论计算相结合,可准确得出支架位置在0.8倍跨度处主梁自重对主梁上拱度的影响修正值,此时测得的拱度值再减去修正值后就是准确的拱度值。

The impact of relative residence times on the distribution of heavy drinkers in highly distinct environments

Alcohol consumption is a function of social dynamics, environmental contexts, individuals' preferences and family history. Empirical surveys have focused primarily on identification of risk factors for high-level drinking but have done little to clarify the underlying mechanisms at work. Also, there have been few attempts to apply nonlinear dynamics to the study of these mechanisms and processes at the population level. A simple framework where drinking is modeled as a socially contagious process in low- and high-risk connected environments is introduced. Individuals are classified as light, moderate (assumed mobile), and heavy drinkers. Moderate drinkers provide the link between both environments, that is, they are assumed to be the only individuals drinking in both settings. The focus here is on the effect of moderate drinkers, measured by the proportion of their time spent in “low-” versus “high-” risk drinking environments, on the distribution of drinkers.A simple model within our contact framework predicts that if the relative residence times of moderate drinkers are distributed randomly between low- and high-risk environments then the proportion of heavy drinkers is likely to be higher than expected. However, the full story even in a highly simplified setting is not so simple because “strong” local social mixing tends to increase high-risk drinking on its own. High levels of social interaction between light and moderate drinkers in low-risk environments can diminish the importance of the distribution of relative drinking times on the prevalence of heavy drinking.

吉林省农村居民收入对消费的影响研究

区域农村居民消费水平的高低代表该区域农民的生活水准。随着吉林省经济的发展,全省农村居民的收入也在不断提高,居民消费水平也逐年提高。但近年来,由于吉林省农村居民的消费水平相对较低、居民未来收入不确定性增大、农村人口老龄化加剧、农村社会保障体系不完善、农村消费环境差等原因,使农村居民消费率一直呈下降趋势,居民消费不足。吉林省应加快提高全省农村居民的收入,健全农村社会保障体系,并努力提供良好的农村消费环境,以有效促进农民消费,提高其生活水平。     

Upward influence tactics and their effects on job performance ratings and flexible working arrangements: The mediating roles of mutual recognition respect and mutual appraisal respect

Supervisor's human resources (HR) decisions have a significant impact on the employees they manage but have been found to be subject to bias. The upward influence tactics use by subordinates can play a role in this. We investigated the effects of seven upward influence tactics on supervisor job‐performance ratings and the extent of subordinate flexible working arrangements (FWAs). Supervisors are often responsible for determining whether employees are granted FWAs. We posit an alternative theoretical mechanism by which upward influence tactics bring about their effects, mediated through two distinct types of respect, mutual appraisal respect and mutual recognition respect. We collected data from 389 matched supervisor–subordinate dyads, and found that both mutual appraisal respect and mutual recognition respect mediated relationships between several upward influence tactics and both job‐performance ratings and FWAs. Our findings show that upward influence tactics affect the quality of the relationship between employees and their supervisors, specifically, these two forms of mutual respect. Further, both mutual appraisal respect and mutual recognition respect may explain why supervisors show favoritism to some subordinates over others, in reaching HR decisions in these areas.

Urban Influence on Costs of Production in the Corn Belt

This article determines the relative technical efficiency of rural- and urban-influenced crop/livestock enterprises in the Corn Belt. Farmers in urban-influenced locations are less technically efficient than farmers in rural locations. During 1998–2000, stochastic production frontier procedures indicate that a 10% increase in urban influence leads to a close to 4% decrease in technical efficiency. The most successful urban-influenced farms have controlled costs as effectively as rural farms. They have tended to de-emphasize that nondairy livestock activities—particularly beef and hogs—do not rely extensively on off-farm income, and have relatively large, less residential/lifestyle operations compared to less successful urban-influenced farmers. However, our statistical analysis clearly bears out the refrain in popular literature that urban proximity raises the cost for, and decreases the viability of, traditional farms.
