Every social science researcher must make a number of methodological decisions when planning and implementing research projects. Each such decision carries with it both advantages and limitations. The decisions faced and made by Regnerus (2012) are discussed here in the wider context of social science literature regarding same-sex parenting. Even though the apparent outcomes of Regnerus’s study were unpopular, the methodological decisions he made in the design and implementation of the New Family Structures Survey were not uncommon among social scientists, including many progressive, gay and lesbian scholars. These decisions and the research they produced deserve considerable and continued discussion, but criticisms of the underlying ethics and professionalism are misplaced because nearly every methodological decision that was made has ample precedents in research published by many other credible and distinguished scholars. 相似文献

Personal Values as Mitigating Factors in the Link Between Income and Life Satisfaction: Evidence from the European Social Survey 总被引:1,自引:0,他引:1
Using data from the first two rounds of the European Social Survey, we examine the link between income, reference income and
life satisfaction across Western Europe. We find that whilst there is a strong positive relationship between income and life
satisfaction, reference or comparison income exerts a strong negative influence. Interestingly, our results confirm the importance
of personal values and beliefs not only as predictors of subjective well-being, but also as mitigating factors in the relationship
between income, reference income and life satisfaction. While our findings provide additional empirical support for the relative
utility hypothesis, they are also consistent with Rojas’ (J Econ Psychol 28:1–14, 2007) Conceptual-Referent-Theory (CRT), which is based on the premise that the salience of income and comparison income depends on one’s intrinsic values
and personal beliefs.

The European Social Survey, on which this issue of the journal focuses, is a 30-nation multi-funded survey series measuring
attitude change. Started in 2001, it is characterised by unusually high standards of sampling and data equivalence. Its data
are made available on-line with equal access to all, and have already attracted over 20,000 users. Many papers, articles and
books based on the ESS have already appeared. But none has yet employed the data—whether alone or with other sources—to derive
indicators of citizens’ cognitive judgements of their society. A recent EC grant is enabling the authors to fill this gap,
covering topics such as trust in national institutions, tolerance, social cohesion, social trust and fear of crime. The aim
is to be able to monitor changes over time in the distance between what citizens believe their society ought to be in these
respects and how they actually perceive it to be.

Objective: To determine if weight gain is accompanied by development of insulin resistance (IR) during 4 years in college. Participants: Two cohorts of college students were enrolled in fall semesters 2009 and 2010 and tracked for 4 years. Methods: Following a 12-hour fast, subjects reported for measurement of body mass index (BMI), perceived stress (PSS), aerobic fitness, and blood glucose, insulin, and lipids. Results: In the first year, 33% of subjects were overweight or obese, and 20% were hyperinsulinemic. Year 4 had 29 remaining subjects with disproportionate attrition of overweight and obese individuals. Just over half the subjects gained weight (WI), whereas nearly 30% lost considerable amounts (WD). WD showed significant decline in fasting insulin, low-density lipoprotein (LDL) cholesterol, and PSS from year 1. WI was primarily highly fit men who did not demonstrate increased IR. Conclusion: WI was not associated with IR over 4 years of college. 相似文献

With the integration of evidence-based practice central to all areas of social work education and training across the globe, it is crucial that we continue to engage with the methodological challenges inherent in gathering this evidence, particularly when it is related to the nature of social work education itself. As a result, this paper addresses some of the methodological challenges involved in examining the education available to social workers on engaging with substance use, both within the social work academy and local authorities in England. Drawing on experiences of implementing large scale online surveys from three substantial research projects completed by the authors, this paper highlights four methodological themes: (1) Constructing a representative sampling frame; (2) Identifying participants within organisations with many departments; (3) Response rates; and (4) Questionnaire design. While these are familiar methodological considerations, this article draws attention to the specific complexities of gathering ‘representative’ knowledge to inform educational strategies on substance use within social work education and employment contexts. Finally this paper offers lessons learned and guidance for social work academics, students and practitioners who are minded to build, or draw from, an evidence-base using representative samples from and within these environments. 相似文献

Numerous scholars documented declines in America's social capital through the mid‐1990s but we do not know whether the trend has continued. Further, despite warnings by Robert Putnam and Theda Skocpol that the quality of Americans' voluntary association memberships has also deteriorated—moving from active, “face‐to‐face” memberships to passive, “checkbook” memberships—data have not been available to test this claim. In this article, we use both the Iowa Community Survey and the General Social Survey to explore the changing nature of voluntary association membership between 1994 and 2004. We demonstrate that not only are declines in voluntary association memberships continuing in the new century but there has been a shift in the intensity of voluntary association participation over time. We observe a decline in active membership over time and an increase in checkbook membership over time. These findings provide support for Putnam's claim that checkbook membership is increasing at the expense of more active types of memberships. 相似文献

文章从国家创新体系角度,对创新能力测度相关的理论基础、方法工具、科技统计调查及中国的研究与实践进行全面梳理和分析。国家创新能力测度的发展与实践表明:国家创新体系理论(NIS理论)以系统论为指导全面考察创新活动的发生机制,为准确测度国家创新能力提供了有力支撑;不同时期形成的创新能力测度方法与当时占主流地位的创新理论密切相关;当前占主导地位的测度方法可分为建模计量法、综合指标法和DEA效率评价法三类,都是以NIS理论为支撑的;规范的科技统计调查是准确测度创新能力的前提,OECD是这方面的典范,其经验为发展中国家提供了参考依据;中国学者在测度方法的探索上有诸多独到之处,但国内科技统计调查工作仍有待进一步规范。 相似文献

PURPOSE: We need solid estimates of maternal mortality rates (MMR) to monitor the impact of maternal care programs. Cambodian health authorities and WHO report the MMR in Cambodia at 450 per 100,000 live births. The figure is drawn from surveys where information is obtained by interviewing respondents about the survival of all their adult sisters (sisterhood method). The estimate is statistically imprecise, 95% confidence intervals ranging from 260 to 620/100,000. The MMR estimate is also uncertain due to under-reporting; where 80-90% of women deliver at home maternal fatalities may go undetected especially where mortality is highest, in remote rural areas. The aim of this study was to attain more reliable MMR estimates by using survey methods other than the sisterhood method prior to an intervention targeting obstetric rural emergencies. PROCEDURES: The study was carried out in rural Northwestern Cambodia where access to health services is poor and poverty, endemic diseases, and land mines are endemic. Two survey methods were applied in two separate sectors: a community-based survey gathering data from public sources and a household survey gathering data direct from primary sources. FINDINGS: There was no statistically significant difference between the two survey results for maternal deaths, both types of survey reported mortality rates around the public figure. The household survey reported a significantly higher perinatal mortality rate as compared to the community-based survey, 8.6% versus 5.0%. Also the household survey gave qualitative data important for a better understanding of the many problems faced by mothers giving birth in the remote villages. There are detection failures in both surveys; the failure rate may be as high as 30-40%. PRINCIPLE CONCLUSION: Both survey methods are inaccurate, therefore inappropriate for evaluation of short-term changes of mortality rates. Surveys based on primary informants yield qualitative information about mothers' hardships important for the design of future maternal care interventions. 相似文献
