Parental education, children's performance and the transition to higher secondary education: trends in primary and secondary effects over five Dutch school cohorts (1965–99)

According to Boudon, social background affects educational transitions as a result of differences in children's academic performance (primary effects) and differences in transition probabilities given children's level of academic performance (secondary effects). This study addresses historical changes in both primary and secondary effects on the educational transition from primary school to higher secondary education in the Netherlands. In addition, it considers changes over time in the relative importance of these effects. The study compares five cohorts of Dutch pupils, specifically those enrolling in secondary education in 1965, 1977, 1989, 1993 and 1999, and it employs counterfactual analyses. The main findings are that secondary effects have been stable and primary effects have fluctuated to some extent. As a result, the proportion of the total effect of social background accounted for by primary effects has increased somewhat, from 53 per cent to 58 per cent.     

Midnight regulations and the Cinderella effect

Recent studies have shown preliminary evidence of a tendency for outgoing administrations to generate a flurry of last-minute regulatory activity. This so-called Cinderella effect is described as resulting from the combination of an administration being in power yet, because it is out-going, not being subject to political ramifications from its actions. In this paper, we look at monthly regulatory activity over the past 30 years and compare the baseline growth in regulations (measured using the proxy of pages in the Federal Register) to the growth immediately following a Presidential election when the sitting President is re-elected, not re-elected, and when the party in control of the White House changes. We find significant evidence supporting the existence of a Cinderella effect.     

日语动词体的表达方式

体是日语动词重要的语法法范畴之一。体表示动作或状态所具有的内在界限。日语动词体的表达方式有三种 :一是动词连用形后通过接续动词“て”,再接补助动词 ;二是动词连用形后直接接辅助动词 ;三是借助于一些惯用型来表达。关于体的分类 ,诸家提法不一。笔者从中国学生学习和理解的角度着眼 ,参照语法学派的一般观点 ,分成 8大类 :即将体 ,起始体 ,持续体 ,存续体 ,完成体 ,备放体 ,趋向体 ,试做体     

从人类中心主义到生态中心主义伦理观的转变——兼论道德共同体范围的扩展

人类中心主义伦理观是生态危机的价值根源。伴随着从人类中心论到生态中心论的伦理变革 ,人类道德共同体和权利主体的范围从人扩展至非人类存在物。这种生态伦理观的转变为当代生态法学提供了伦理学基础

Metabolic impact of shift work

In developing countries, shift work represents a considerable contingent workforce. Recently, studies have shown that overweight and obesity are more prevalent in shift workers than day workers. In addition, shift work has been associated with a higher propensity for the development of many metabolic disorders, such as insulin resistance, diabetes, dislipidemias and metabolic syndrome. Recent data have pointed that decrease of the sleep time, desynchronization of circadian rhythm and alteration of environmental aspects are the main factors related to such problems. Shortened or disturbed sleep is among the most common health-related effects of shift work. The plausible physiological and biological mechanisms are related to the activation of the autonomic nervous system, inflammation, changes in lipid and glucose metabolism, and related changes in the risk for atherosclerosis, metabolic syndrome, and type II diabetes. The present review will discuss the impact of shift work on obesity and metabolic disorders and how disruption of sleep and circadian misalignment may contribute to these metabolic dysfunctions.     

Ergonomic evaluation of the preparation of cuttings and minicuttings for eucalyptus seedling production, with the use of scissors

This study was conducted in a nursery for eucalyptus seedling production in a forest Company, located in the southern state of Bahia, Brazil. It aimed to evaluate the ergonomic conditions of the preparation of cuttings and mini-cuttings with scissors for Eucalyptus seedling production to increase well-being, satisfaction and safety and minimizing the occurrence of occupational diseases, also improving the process efficiency and final product quality. Environmental conditions, levels of noise, postures, RSI risk and physical workload were assessed. The environmental conditions complied with the recommended norms, except at certain times of day, when workers should make compensation breaks. The workers that collect minicuttings presented postures classified as normal by OWAS. On the other hand, the posture of workers dealing with cutting preparation requires corrections in a short run. The workers were subjected to moderate RSI risk due to the high degree of repeatability found. The physical workload was classified as mild, with no need for ergonomic interventions.
