不同类型农户土壤保护认知及行为决策研究——以江汉平原368户农户调查为例

利用江汉平原农户调查数据,运用二元选择模型分析不同类型农户土壤保护认知与行为决策。结果表明:不同类型农户的土壤保护认知水平存在差异,且农户的土壤保护认知与其行为决策之间的差距较为明显;户主教育程度、农户土壤保护认知与耕地块数是影响所有类型农户土壤保护行为决策的显著因素;是否租入土地与接受农业技术培训对纯农户土壤保护行为有显著影响;人均耕地面积对I兼农户有显著影响;户主是否兼业与家庭非农就业比例对II兼农户有显著影响;户主年龄对III兼农户有显著影响。由此提出建议:提高各类农户土壤保护认知,缩小农户行为决策与认知差距的关键在于加强土壤保护知识与技术的宣传,培养农户土壤保护意识与技能,并通过土地整理等措施为农户采取土壤保护行为提供便利条件,在保障各方收入来源的基础上,引导土地从III兼农户向专业经营户流转。     

Formative research methods to understand patient and provider responses to heart attack symptoms

Formative research is often required for program planning, and for reducing uncertainty about generalizability of program effects. This article describes and justifies methods of formative research conducted for the REACT study (Rapid Early Action for Coronary Treatment), a multi-center collaborative randomized community trial aimed at reducing patient delay in seeking care for acute myocardial infarction (AMI). Formative research cast light on patient and community members’ decision-making process in seeking help for AMI, as well as barriers and facilitators of this process. Investigators at all five REACT Field Centers participated in the formative research. The process consisted of: (1) developing a common theoretical framework for the study intervention; (2) conducting a literature review and qualitative research to identify and address gaps in knowledge; and (3) developing a common protocol for the REACT study that accommodated the diversity of the target communities in terms of services, resources, history, and ethnicity. Analysis employed triangulation, defined as an explicit search for heterogeneous data sources to reduce uncertainty about forces at work and opportunities for intervention across settings and populations. Because the collection and interpretation of data went in stages, staff of several REACT Field Centers had independent input to the overall synthesis, then shared and revised the results. Advantages and limitations of this approach are discussed.     

Maltreatment and Trauma: Toward a Comprehensive Model of Abused Children from Developmental Psychology

Knowledge of how maltreatment and trauma aects personality functioning in abused children has been greatly enhanced by clinical theory and research in developmental psychology. Developmental research and theory has allowed the child abuse field to move beyond symptom-lists toward broader models of how trauma impacts major domains of personality functioning. However, these models continue to be based largely on discrete theories of development that parallel, if not confound, one another. This paper attempts to expand our understanding of the traumatized child by using the synthetic model of personality development expounded by Fred Pine that promotes a more holistic and comprehensive view of the abused child and, thus, enhances clinical theory and intervention.

The ethics of using Nazi medical data: a Jewish perspective

The notorious experiments on concentration camp prisoners conducted by Nazi scientists produced a body of data still referred to by researchers. The Jewish tradition offers resources for deciding on the morality of using this material.     

College student binge drinking and the "prevention paradox": implications for prevention and harm reduction

Considerable attention has been paid to heavy episodic or "binge" drinking among college youth in the United States. Despite widespread use, the binge measure is perceived by some as a low intervention threshold. We use data from the Harvard School of Public Health College Alcohol Study (n = 49,163) to describe patterns of consumption and harms along a continuum including the binge measure to demonstrate the validity of the binge threshold and prevention paradox in college. While the heaviest drinkers are at greatest risk for harm, they are relatively few and generate proportionately small amounts of all drinking-harms. The risk of harms is not zero among lower level drinkers in college. Because they are numerous, they account for the majority of harms. This paradoxical pattern suggests we moderate consumption among the majority using environmental approaches, the efficacy of which are described using case study data from a national prevention demonstration. Implications for prevention policy, programming, and media advocacy are discussed.     

母系家园(英文)

这是一个28户人家的小村庄,坐落在川滇两省交界处崇山峻岭中,至今尚没有道路能够通达。它是当年茶马古道的必经之路,小村子也因此得名——里加咀(摩梭语译音),摩梭语的意思是"中间休息的地方",或"灵魂聚集的地方"。这个鲜为人知的小村庄,堪称早期母系氏族的缩影。     

What colleges are doing about student binge drinking. A survey of college administrators

In 1999, the Harvard School of Public Health College Alcohol Study surveyed 734 US college administrators to learn what colleges were doing to prevent binge drinking. Respondents rated the severity of student alcohol-abuse problems and described prevention efforts and institutional investments in prevention infrastructure. Prevention practices were widespread in the areas of general education about alcohol, use of policy controls to limit access to alcohol, restricting advertising at home-game sporting events, and allocation of living space to alcohol-free dormitories. Programming was less prevalent for more targeted alcohol education, outreach, and restrictions on alcohol advertising in campus media. Nationally, most of the surveyed colleges reported having a campus alcohol specialist, many had task forces, and about half were performing in-house data collection. Less common were program evaluations, community agreements, or neighborhood exchanges. Prevention practices varied with institutional characteristics and the surveyed administrators' perceptions of the severity of alcohol problems.
