Adolescent injuries in relation to economic status: An international perspective

The primary objective of the study was to examine the relationship between patterns in car-to-car crashes involving young drivers and car and driver characteristics and the research design was a national register-based prospective cohort study. Individual records in a cohort born 1970 – 1972 are linked to road-traffic-crash data (1988 – 2000). Subjects' first police-registered two-car crash leading to severe or fatal injury (n = 4875) are identified. Typical crash patterns are highlighted and associations between pattern and both car and individual socio-demographic characteristics are tested. Four crash patterns are highlighted. Male drivers and those with lower educational attainment are over-represented in all patterns. Pattern-based risk levels vary considerably according to car safety level and driver's age at time of injury and socio-economic status. Crash patterns might be considered in young adult driver education systems, bearing in mind the consistent higher risks of male drivers and of drivers with lower educational attainment.     

林地与农地制度变革的比较：产业特性的视角

土地制度改革一直是关系农村发展及社会稳定的重大问题。本文从产业特性的差异出发，对改革开放后林地与衣地制度改革路径中的制度安排与改革影响进行了比较，认为制度安排具有与产业特性相容的内在诉求，由于产业特性差异，林地制度对农地制度的简单复制难以凑效且不可持续，深化集体林权制度改革需要重视对林业特征的考察。     

产业多元化：微型经济体国际比较

澳门产业多元化问题是内地和澳门特区政府以及学术界十分关注的问题。根据产业组织理论,对澳门以及和澳门类似的3个经济体——卢森堡、冰岛和马耳他的产业部门数量和各产业部门在整个经济中的分布进行了比较。使用就业人口和GDP数据计算出的熵指数和赫芬达尔指数显示,澳门的产业多元化程度低于卢森堡、冰岛和马耳他。研究也发现：导致澳门产业多元化程度低的主要原因不是澳门产业部门的数量少,即所谓的＂产业结构单一＂,而是各产业在澳门整个经济活动中的比重不均衡,即所谓的（博彩产业）＂一业独大＂。研究结论可为澳门特区政府制定产业多元化政策提供参考借鉴。

关于国内外社会比较的研究综述

1954年，费斯廷格第一次提出了社会比较的概念和理论。他认为这种把自己的观点和能力与他人进行比较的过程是评价自己观点和能力的驱力，并影响个体的行为。近年来，不断有研究者将企业或团队内部的社会比较作为研究重心，以探求社会比较对个体绩效、工作热情、倦怠感之间的关系。本文详尽地归纳和总结了目前国内外对社会比较的研究成果和结论。     

Black–white differences in beliefs about the U.S. restaurant tipping norm: Moderated by socio-economic status?

A re-analysis of two national telephone surveys found that black–white differences in awareness that it is customary to tip a percentage of the bill declined as socio-economic status increased. However, black–white differences in awareness that is customary to tip 15–20 percent in restaurants was unrelated to socio-economic status. The practical as well as theoretical implications of these findings are discussed along with directions for future research.
