论“基本经济规律”——文明时代：奴隶社会

在奴隶社会里,物质资料的生产和分配依然遵循使用价值规律发展.与原始社会不同的是,它不是循着一般产品的使用价值,而是循着一种特殊物品的使用价值--奴隶的使用价值而发展.奴隶将其劳动力剩余部分所创造的财富全部无偿地献给奴隶主.所以,奴隶社会的基本经济规律,就是以使用价值规律为基础的剩余劳动力的使用价值,即剩余劳动规律.     

Household technology: Implications for research and policy

If we are to have a fuller understanding of the social and economic context of the family, it is necessary to explore its technological environment. However, few scholars have examined the relationship between household technology and the functioning of the family. This article looks at which academic disciplines address household technology, what have been their findings, and why there is generally a paucity of research in this area. This article concludes with a discussion of the need for more research in household technology and the implications that this research may have for other family inquiry and for policy formation.Cathleen Zick, University of Utah, Richard Widdows, Purdue University, and Joan Ash, Central Washington University, provided helpful comments on earlier drafts of this article.His research interests include household technology, consumer policy, and consumer protection.

刍议大学英语后续教学

大学英语后续教学是大学四年英语学习不断线的保证,也是提高大学生英语应用能力的关键。但是,由于课程设置、师资等原因,大学英语的后续教学工作没有得到充分重视。为了适应社会和经济的发展,加强大学英语后续教学势在必行。作者通过自身的教学实践,对目前大学英语后续教学存在的问题,教学目标、课程设置等进行了探讨。

说说“成语的化用”

成语固然具有意义上的完整性,结构上的凝固性,不能随意颠倒顺序,不能随意替换其中的字词,但也 不是完全不许根据需要做临时的变动,因为成语活用是早就存在的语言现象。

Alcohol’s Effects on Video Lottery Terminal (VLT) Play Among Probable Pathological and Non-Pathological Gamblers

This study tested whether alcohol increases behaviors associated with video lottery terminal (VLT) play, particularly among probable pathological gamblers. Forty-four regular VLT players were designated either probable pathological gamblers or non-pathological gamblers on the basis of scores on the South Oaks Gambling Screen (SOGS); [Lesieur & Blume (1997). American Journal of Psychiatry, 144, 1184–1188] Gamblers from each SOGS category were randomly assigned to either a moderately intoxicating alcohol dose or a control beverage condition (n = 11 per cell in the 2 × 2 between-subjects design). Following beverage consumption and absorption, participants played a video poker VLT game for up to 30 minutes. Four behaviors were measured: “power-bets” (doubling bet after viewing only two cards of the five-card poker hand); total money spent; mean bet magnitude; and number of minutes played. Alcohol increased time spent playing and rate of power-bets, particular among the probable pathological gamblers. Post hoc analyses revealed that alcohol also influenced the proportion of losing hands played––increasing them among the probable pathological gamblers while decreasing them among the non-pathological gamblers. Clinical and policy implications of the findings are discussed.     

Riparian woody plant diversity and forest structure along an urban-rural gradient

Changes in riparian woody plant assemblages are anticipated in the southeastern United States due to increases in urbanization rates. Because riparian forests serve important roles in maintaining water quality and biodiversity, understanding how they respond to urbanization is crucial. The objective of this study was to examine forest structure and woody vegetation diversity indices of riparian communities in response to an urbanization gradient in West Georgia, USA. Measures of forest structure and diversity were compared to measures of urbanization and land cover. Although Liquidambar styracifluaand Quercus nigrawere dominant species in the forest stand and regeneration layer for all riparian communities, the invasive, non-native shrub Ligustrum sinense was the most dominant species observed in the regeneration layer for urban, developing, and agriculture communities. The proportion of non-native species in the forest stand and regeneration layer decreased and Shannon diversity of the regeneration layer increased with increasing distance from the urban center. Shifts in diversity indicate that anthropogenic disturbance may subdue the ability of diverse communities to resist non-native plant invasions.
