Avian Influenza in Vietnam: Chicken‐Hearted Consumers?

This study, based on quantitative and qualitative surveys conducted from July 2004 to September 2005, examines the perceptions of Hanoi consumers and their reactions to the Avian Influenza epizootic (H5N1). Hanoi consumers clearly link the risk of human contamination by the virus to the preparation and ingestion of poultry. During the first crisis, consumers reacted quickly and intensely (74% of them had already stopped eating poultry in January 2004). Nevertheless, once the crisis abated, they quickly resumed their consumption of poultry. This behavior corresponds to the pattern described by empirical studies of other crises, such as BSE. What is more surprising is the speed with which the different steps of this common pattern succeeded one another. It may be explained by a rapid decrease in risk anxiety. A logit model shows that, soon after the beginning of the crisis, AI risk anxiety was tempered by confidence in the information and recommendations issued by the government concerning AI and, in the long term, by a high perceived self-efficiency to deal with AI. Indeed, not only has poultry consumption been affected in terms of the quantity consumed, but alternative ways of selecting and preparing poultry have also been adopted as anti-risk practices. Risk communication strategies should take this into account, and rely on a previous assessment of consumer practices adopted to deal with the risk.

浆细胞膜糖蛋白基因K121Q变异与老年人2型糖尿病的关联研究

目的探讨浆细胞膜糖蛋白基因(PC-1)4号外显子K121Q变异与老年人2型糖尿病的相关性。方法自2006年北京市社区2型糖尿病调查资料中选出有糖尿病家族史,且相互间无亲缘关系的老年2型糖尿病患者228例,同时选择非糖尿病健康老年对照人群308例。所有受试者均签署知情同意书,所有受试者均为汉族。应用聚合酶链反应-限制性片段长度多态性(PCR-RFLP)方法,检测PC-1基因K121Q的多态性分布情况。结果老年2型糖尿病患者中KK基因型177例(77.6%),KQ基因型46例(20.2%),QQ基因型5例(2.2%),K、Q等位基因频率分别是87.7%和12.3%;正常老年对照组中KK基因型239例(77.6%),KQ基因型63例(20.5%),QQ基因型6例(1.9%),K、Q等位基因频率分别是87.8%和12.2%;PC-1基因K121Q变异的基因型频率和等位基因频率在两组中的分布差异无显著性(P>0.05);PC-1基因K121Q变异的基因型频率和等位基因频率在男性和女性中的分布差异也无显著性(P>0.05);PC-1基因K121Q变异的KK基因型组与KQ QQ基因型组中的肥胖指标的特征差异也无显著性(P>0.05)。结论PC-1基因K121Q变异可能与老年人2型糖尿病的易感性无关联。     

Religion,social milieu,and the contraceptive revolution

This study examines how the social environment of religious congregations affects the spread of contraceptive use in developing contexts, using Mozambique as a case study. Analysis of qualitative data collected in urban areas of that country in 1998-99 and of the data from the 1997 Mozambique Demographic and Health Survey suggests that, in urban areas, the environment of more socioculturally diverse and inclusive Roman Catholic and mission-based Protestant congregations is more propitious to the spread and legitimization of modern contraception than the milieu of smaller, relatively homogeneous, independent churches. In rural areas, however, sociocultural diversity within and across different religious denominations is minimal, and membership in any formal congregation offers an advantage in contraceptive learning.     

Insecurity related to working life by age groups in Finland and Estonia in the 1990s

This article compares the reasons for insecurity related to working life in different age groups in Finland and Estonia, and the coping strategies evident in the two countries. Insecurity related to working life is more common in Finland than in Estonia. The differences between the two countries are more distinct with respect to experienced work-related insecurity than to an experienced lack of well-being linked to work. This shows that feelings of insecurity are affected not only by external factors, but also by internal factors linked to a person's earlier development. The most common causes of insecurity for people of working age are unemployment, mental strain and difficulties in interpersonal relationships at the work place. The individual's willingness to find means of coping at work is more clearly evident in Estonia than in Finland. People of working age in Finland are more likely to attempt to change the external conditions of work than are their Estonian counterparts.

进入2007年,我国的经济通胀出现加速趋势,并具有明显的结构性、区域性和阶段性特征,对我国的宏观经济安全构成一定威胁。现从货币需求理论的视角,探讨我国经济通胀的原因,提出制定应对通货膨胀的政策。更多从马克思的货币流通规律理论和弗里德曼的现代货币数量论入手,综合运用调控货币流动性和货币供求的多种工具,提出了问题的解决策略。     

Do Drivers of Small Cars Take Less Risk in Everyday Driving?

Previously reported observed data on risky everyday driving are brought together and reanalyzed in order to focus on the relation between risky driving and the size of the car being driven, as indicated by car mass. The measures of risky driving include separation between vehicles in heavy freeway traffic and speed on a two lane road. Observed seat belt use provides a third measure of driver risk. Confounding effects arising from the observed association between car mass and driver age are taken into account by segmenting the data into three driver age groups. Driver risk taking is found to increase with increasing car mass for each of these three aspects of everyday driving. The implications of these results with respect to driver fatality rates are discussed in terms of a simple model relating observed risky driving to the likelihood of involvement in a severe crash.
