To let hair be,or to not let hair be? Gender and body hair removal practices in Aotearoa/New Zealand

Research and anecdotal evidence suggest women continue to remove body hair, and there is some evidence for cultural changes in men's hair removal practices. This paper reports on data collected using an online mix-methods survey from 584 New Zealanders between the ages of 18–35 (mean age 26, 48.9% male, 50.6% female). The data demonstrated that substantial proportions of both women and men in Aotearoa/New Zealand remove body hair from many sites. However, gendered differences remain, and a key dimension of gendered difference appears in the concept of flexible choice around body hair removal or retention. This was seen in the difference between perceived acceptability of having body hair (81% for men, 11% for women). These findings suggest that although men, like women, are now coming under some pressure to remove body hair, there is still a great difference in men and women's capacity to choose whether to bow to it.     

Comparing Paper-and-Pencil and Internet Survey Methods Conducted in a Combat-Deployed Environment

The Unit Behavioral Health Needs Assessment Survey (UBHNAS) is a tool used to aid behavioral health providers in assessing the needs of service members of a military unit. Traditionally, the survey has been administered by paper-and-pencil; however, implementing the survey via the Internet may be a faster and easier way to administer the survey. There are, however, potential drawbacks to Internet survey administration, and previous studies comparing the 2 methods have yielded inconsistent findings. Using a between-subjects design with a combat-deployed military sample, the present study compared the 2 survey administration methods. Specifically, we assessed comparability for (a) psychological constructs, (b) auxiliary measures (such as completion time, frequency of missing data, and length of written comments), and (c) ratings and perceptions of the UBHNAS, and preference in methodology. The method of survey administration did not predict differences in the psychological outcome variables. However, participants in the paper-and-pencil condition reported higher rates of comfort answering questions, belief that responses would remain anonymous, and frankness and honesty in answering questions. Nevertheless, participants in both conditions preferred to take the survey via the Internet as opposed to paper-and-pencil in the future. Finally, participants in the Internet condition completed the survey faster and tended to write longer comments, although in terms of the comments being informative, there was no difference between the groups. Based on our findings, we recommend the use of the Internet for administering the UBHNAS; however, we caution that there may be tradeoffs regarding concerns about comfort, honesty, and anonymity.

Assessment of Multiple Membership Multilevel Models: An Application to Interviewer Effects on Nonresponse

Multilevel multiple membership models account for situations where lower level units are nested within multiple higher level units from the same classification. Not accounting correctly for such multiple membership structures leads to biased results. The use of a multiple membership model requires selection of weights reflecting the hypothesized contribution of each level two unit and their relationship to the level one outcome. The Deviance Information Criterion (DIC) has been proposed to identify such weights. For the case of logistic regression, this study assesses, through simulation, the model identification rates of the DIC to detect the correct multiple membership weights, and the properties of model variance estimators for different weight specifications across a range of scenarios. The study is motivated by analyzing interviewer effects across waves in a longitudinal study. Interviewers can substantially influence the behavior of sample survey respondents, including their decision to participate in the survey. In the case of a longitudinal survey several interviewers may contact sample members to participate across different waves. Multilevel multiple membership models are suitable to account for the inclusion of higher-level random effects for interviewers at various waves, and to assess, for example, the relative importance of previous and current wave interviewers on current wave nonresponse. To illustrate the application, multiple membership models are applied to the UK Family and Children Survey to identify interviewer effects in a longitudinal study. The paper takes a critical view on the substantive interpretation of the model weights and provides practical guidance to statistical modelers. The main recommendation is that it is best to specify the weights in a multiple membership model by exploring different weight specifications based on the DIC, rather than prespecifying the weights.     

Unemployed people in search of a job: Reconsidering the role of search behavior

A three-wave longitudinal study of unemployed persons in Croatia was used to examine the antecedents of job-seeking behavior and reemployment. A series of demographic, motivational and job-constraint variables were posited to influence job-seeking behavior, which, in turn, was hypothesized to affect (re)employment. The participants were surveyed in 2003 (N = 1138), and their employment status was checked in 2004 (N = 601) and 2005 (N = 452). Regression analyzes supported only one slice of the model—the antecedent-job-search relations. All motivational variables, in particular employment commitment and perceived financial strain, proved to be relatively strong predictors of job-search intensity. However, they appeared to be only weakly related to the (re)employment outcome. Demographic variables—in particular education, age, and employment duration—appeared to be the main determinants of (re)employment, operating presumably through their influence on employers’ hiring decisions. It was suggested that existing theory and heuristic frameworks overstate the importance of job-seeking activity. Further research is suggested to examine why purposeful and proactive job searching does not pay more.     

跨期选择的性质探索

跨期选择指人们对发生在不同时间点的价值做出的权衡与决策。大量研究证明, 跨期选择中人们存在普遍的时间折扣倾向, 即将未来的价值折扣后与当前价值进行权衡。跨期选择研究不仅与人类心智的起源与机制等基础科学问题密切相关, 也关系到国家公共政策的制定等现实问题。本项目拟采用实验室研究和大规模问卷调查结合的方法, 深入探索跨期选择的本质。一方面, 采用实验室研究法探讨影响跨期选择的重要因素, 以探索：(1) 跨期选择的效价及其与价值数量、延迟时间的交互作用及其心理机制; (2) 跨期选择中是否存在领域特异性及其心理机制; 另一方面, 通过全国范围的调查, 从而：(1) 建立中国城镇居民时间折扣率的常模; (2) 测量不同类型人群的时间折扣率, 以探讨跨期选择的性质与内涵。项目研究结果将有利于加深学界对跨期选择现象的理解。
