Risk Perceptions and Alcohol Consumption among Young People

Swedish cross-sectional survey data on young individuals was used to analyse the determinants of perceived risks of alcohol use and how these perceptions relate to drinking behaviour. Three major conclusions were drawn: (1) that people overestimate the risks of alcoholism, (2) that these risk perceptions fall substantially with age, but nevertheless imply risk overestimation, and (3) that education about alcohol, narcotics and tobacco leads individuals to perceive risks more correctly and to have lower risk beliefs. An additional finding was that individuals with higher perceived risks were less likely to consume alcohol. Equations were estimated both separately and simultaneously.

微波放大器增益与噪声关系的分析方法

提出了一种在微波宽带低噪声放大器设计中，放大器增益性能与噪声性能之间关系的解析表达式，对其解析解进行了详尽的讨论，大大简化了传统的设计过程，并对微波低噪声ＨＥＭＴ器件ＪＳ８９０５－ＡＳ的性能进行了分析设计，经验证，与传统方法的结果相吻合。     

经典美学的危机与大众美学的崛起

在消费主义的意识形态笼罩下,日常生活的意义被放大为文化的中心并被神圣化,而昔日的现代性的神圣价值则被日常化;技术和市场在文化领域的强力介入使当今时代出现了一种明显的文化泛化与审美泛化的趋势。从经典艺术美的陶冶到关注身体感觉和生理欲念的快感美学,从经典艺术的“人”之代言到当代文化的大众体验,从经典艺术的文字想像到大众文化的图像复现,从经典艺术的观念幻象到大众文化的身体喜剧,经典美学迅速进入了自身的当代转型和现实重构,其文化立场和理论视域理应做出全面调整。

The energy and mass balance of Los Angeles County

We conducted an urban “metabolic” study of inputs and outputs of food, water, energy, and pollutants from Los Angeles County, USA. This region has been the subject of recent debate about the nature of population density and distribution as it relates to urban form and associated environmental impacts. We found that with the exception of food imports and wastewater outputs, inputs of resources and outputs of pollutants generally declined on a per capita basis from 1990 to 2000. Reductions likely reflected a combination of changes in public policy, improvements in technology and public infrastructure, and impacts of increases in population density. However, in comparison to other municipalities and urban regions, resource consumption per capita was still relatively high in some categories, particularly inputs of water and transportation energy. Per capita greenhouse gas emissions were lower in Los Angeles County than for the average of the USA as a whole but higher than previous analyses of urban areas internationally, largely due to comparatively high emissions from the transportation sector. Wastewater discharge accounted for less than 40% of water inputs excluding precipitation; however the partitioning of water outputs through other potential losses, specifically evapotranspiration, runoff, and groundwater recharge, remains highly uncertain. We suggest that more detailed information about water losses will greatly improve future mass and energy accounting for analyses of urban environmental sustainability in this semi-arid region.     

论可持续消费观

生态危机与过度消费有关。为寻求人类的共同繁荣和未来的持续发展,必须树立新的消费伦理观,这就是以适度消费为基本原则、以造就高度责任感的消费主体为关键、以确立系统而可行的消费道德为切入点的“可持续消费观”。

论卢卡奇物化理论的当代意义

在《历史与阶级意识》中,卢卡奇把韦伯的合理化理论与马克思对商品拜物教的分析结合起来,提出了物化理论,即人的活动、人自己的劳动成了对自己说来是客观和对立的东西。这一理论引发了法兰克福学派对工具理性和文化工业的批判。后现代主义对消费异化的批判也从这一理论中得到启发。
