This Field Note presents a follow-up to a pilot study that explored pre-field placement anxiety for 1st-year MSW students. Previous studies report that students experience significant anxiety as they anticipate their field placement, and research indicates that anxiety has the potential to affect learning. A sample of 204 students reported moderate levels of anxiety, comparable to previous findings. Older students, and those with prior work and classroom experience, reported significantly less anxiety. Students described specific concerns but also viewed anxiety as an expectable response with positive connotations for enhanced learning. Implications for social work education and future research are discussed.     

Ethnic,gender, and length‐of‐residency influences on sexual knowledge and attitudes

We examined potential differences in sexual knowledge and attitudes between 702 Canadian undergraduates of Asian (n = 356) and European (n = 346) ancestry. We also examined potential influences of length of residency in Canada on these variables among Asians, and the role of gender both across and within ethnic groups. The primary purpose was to examine whether length of exposure to North American sexual values influences sexual knowledge or attitudes among Asians living in Canada. Results revealed that compared to Europeans, Asians held more conservative sexual attitudes and demonstrated significantly less sexual knowledge. Recent Asian immigrants were significantly more likely than Canadian‐born or long‐term Canadian residents to hold conservative sexual attitudes on a number of sexuality items. Among Asians and Non‐Asians, males reported more negative attitudes toward homosexuals than did females; females held more conservative sexual attitudes toward uncommitted sexual relations than did males. The findings provide partial support for a cultural explanation of the frequently reported finding that, compared with North Americans, Asians are more restricted in their expression of sexuality.     

Approximating cross-validatory predictive evaluation in Bayesian latent variable models with integrated IS and WAIC

Looking at predictive accuracy is a traditional method for comparing models. A natural method for approximating out-of-sample predictive accuracy is leave-one-out cross-validation (LOOCV)—we alternately hold out each case from a full dataset and then train a Bayesian model using Markov chain Monte Carlo without the held-out case; at last we evaluate the posterior predictive distribution of all cases with their actual observations. However, actual LOOCV is time-consuming. This paper introduces two methods, namely iIS and iWAIC, for approximating LOOCV with only Markov chain samples simulated from a posterior based on a full dataset. iIS and iWAIC aim at improving the approximations given by importance sampling (IS) and WAIC in Bayesian models with possibly correlated latent variables. In iIS and iWAIC, we first integrate the predictive density over the distribution of the latent variables associated with the held-out without reference to its observation, then apply IS and WAIC approximations to the integrated predictive density. We compare iIS and iWAIC with other approximation methods in three kinds of models: finite mixture models, models with correlated spatial effects, and a random effect logistic regression model. Our empirical results show that iIS and iWAIC give substantially better approximates than non-integrated IS and WAIC and other methods.     

Developing talent with an integrated knowledge-sharing mechanism: an exploratory investigation from the Chinese human resource managers' perspective

Drawing from knowledge sharing and social exchange theory, the paper explores the connection between talent development and knowledge-sharing mechanisms. Based on a preliminary investigation of reviewing the learning experience and career development of 20 Chinese HR practitioners, the findings confirm that incorporating a knowledge-sharing socialization mechanism with talent development programs has a nurturing and supporting effect on learning and development. The mechanism can be used to facilitate organization-wide knowledge sharing and support both organization-led and self-managed talent development programs.     

Effects of Information Sequence and Irrelevant Distractor Information When Using a Computer‐based Decision Aid*

Computer‐based decision aids are intended to support and improve human judgments. Frequently, the largest portion of the design effort is devoted to the technical aspects of the system; behavioral aspects are often overlooked. As a result, the decision aid may be ineffective. An experiment was conducted to examine the effects of two information structure variables that theoretically affect judgments: information sequence and irrelevant distractor information. Auditor subjects made continuing existence judgments for client‐banks after interacting with one of four alternative decision aids. The decision aids are modifications of a system developed by an international CPA firm. Judgments were predicted to be more accurate when: (1) diagnostic information is presented late rather than early in the information sequence and (2) when no irrelevant distractor information is presented. Further, judgment confidence was predicted to be unrelated to either information sequence or irrelevant distractor information. The experimental data support all three predictions.     

Achieving high quality and long‐lasting matches in youth mentoring programmes: a case study of 4Results mentoring

Mentoring programmes show significant promise for enhancing the well‐being of youth with complex needs. Research indicates that high quality mentoring, although difficult to achieve, positively impacts youth development across behavioural, social, emotional and academic domains. The difficulty of sustaining long‐term matches between mentors and youth, however, remains an important concern for the field of mentoring, as foreshortened matches can be harmful to youth. The 4Results mentoring programme has been identified as a Promising Practice through the Washington State Inventory of child‐serving behavioural and mental health programmes and has developed a unique infrastructure to support critical programme values such as match longevity. In 7 years, the programme has successfully retained 98% of mentors for at least 1 year with an average match length of 3.7 years. The following article describes the programme's guiding philosophy and approach to recruiting and training mentors in the context of existing best practices research.     

The impact of a health campaign on hand hygiene and upper respiratory illness among college students living in residence halls

Hand hygiene is a key element in preventing the transmission of cold and flu viruses. The authors conducted an experimental-control design study in 4 campus residence halls to determine whether a message campaign about hand hygiene and the availability of gel hand sanitizer could decrease cold and flu illness and school and work absenteeism. Their findings indicate that students who were exposed to the message campaign and provided with gel hand sanitizer increased their knowledge about the potential health benefits of hand washing and sanitizer use; they reported higher rates of hand washing and using sanitizer than did the control group. These students also experienced fewer cold and flu illnesses during the study than those in the control group and missed fewer class or work engagements because of colds or flu. Conducting a health promotion campaign in residence halls may therefore help prevent colds and flu and decrease absenteeism on university campuses.     

Religiosity,sexual behaviors,and sexual attitudes during emerging adulthood

The current study examined associations between religiosity and sexual behaviors and attitudes during emerging adulthood. Two hundred and five emerging adults completed surveys about five aspects of their religiosity (group affiliation, attendance at religious services, attitudes, perceptions of negative sanctions, and adherence to sanctions) and their sexual behaviors (abstinence, age of onset, lifetime partners, condom use) and attitudes (conservative attitudes, perceived vulnerability to HIV, and condom‐related beliefs). Associations were found between the measures of religiosity and sexuality, although the patterns differed by measures used. Religious behavior was the strongest predictor of sexual behavior. Many aspects of religiosity were associated with general sexual attitudes, which was not the case for perceived vulnerability to HIV and condom‐related beliefs. The findings support reference group theory and highlight the importance of considering the specific constructs of religiosity and sexuality assessed in studies of these topics.
