Some new constructions of strength 3 mixed orthogonal arrays

Orthogonal arrays of strength 3 permit estimation of all the main effects of the experimental factors free from confounding or contamination with 2-factor interactions. We introduce methods of using arithmetic formulations and Latin squares to construct mixed orthogonal arrays of strength 3. Although the methods could be well extended to computing larger arrays, we confine computing to at most 100 run orthogonal arrays for practical uses. We find new arrays with run sizes 80 and 96, each has many distinct factor levels.     

The Management Skills of Russians: Do Work,Management, and Government Experiences Matter?

This study examines the impacts of different types of experience on management skills of working adults in Russia. The study is based on a sample of 527 MBA students, line and middle managers covering 32 regions in 13 different industries in Russia. This study proves that work experience, management experience, and government experience are significant factors in their technical, human, and conceptual skills. Human skills scores are significantly higher for all groups than group with no management experience. Score for human skills increased with years of government experience only, but not with working or management years of experience.     

Virtual World Interview Skills Training for Students Studying Health Professions

This study examined the effectiveness of a health professional virtual world interview skills trainer (IST), in comparison to classroom training via interview role-plays with peers. Students of psychology, physiotherapy, and general health science learned interviewing skills through role-play and virtual world training. Students were randomly allocated to a role-play-first, or IST-first condition. Interviewing self-efficacy was measured at baseline and after each of the learning experiences. In total, 72 students completed all surveys. Students’ reported an increase in interviewing self-efficacy significantly after the IST experience than after role-play.     

City size matters: Vietnamese immigrants having depressive symptoms

This cross-national study identified predictive factors contributing to depression among 691 Vietnamese migrated to the United States who responded to a community survey in two American cities. Measured by HSCL-25, the overall depression prevalence was 30.5%, higher in a large (32.3%) than mid-size city (19.8%). Logistic regression showed that immigration issues, residing in a large city, being female, having health concerns, and experiencing family concerns are significantly related to Vietnamese immigrants having depressive symptoms. Over half (51.4%) of the respondents sought help, and 46.3% preferred seeing their physicians to address mental health issues. Pre-migration counseling is recommended to prevent depression.     

Impact of Public and Private Cash Transfers on Poverty and Inequality: Evidence from Vietnam

This article investigates the extent to which public and private transfers affected poverty and inequality in Vietnam in the mid‐2000s. It finds that the impact of public transfers on poverty was negligible, due to the low coverage of the poor and the relatively small amounts transferred. Moreover, the effect of the receipt of transfers on expenditures was small: recipients decreased the labour supply and only a limited amount of the extra income went to current consumption. Domestic private transfers were somewhat more successful in reducing poverty. With most public and private transfers going to non‐poor households, inequality was only marginally affected.     

The role of visa class in the location choices of immigrants in Australia at the regional and neighbourhood scales

Australia’s pro-immigration policies have played a vital role in national population growth, serving to address what would otherwise be chronic labour shortages and population ageing. While migrants to Australian have shown a clear preference for cities and tend to locate with co-ethnics, variations by visa class—employment, family reunification, and asylum—have yet to be fully explored. This paper aims to identify variations in settlement patterns of immigrants in Australia by visa types and the factors underpinning these choices, paying particular attention to ethnic networks and employment opportunities. We apply a series of negative binomial regressions to aggregate census data linked to visa status. At the suburb level, our results show the importance of the presence of compatriots in shaping the location choices of family migrants, with the exception of skilled and humanitarian immigrants from China, Malaysia and Thailand. At the regional level, skilled migrants, including skilled regional migrants, respond to employment opportunities to a greater extent than family and humanitarian migrants.

     

Voluntary social insurance for Vietnamese laborers in the informal economic sector

Voluntary social insurance (VSI), a type of social insurance organized by the Government, allows participants, who work in the informal sector with unstable jobs and income, to choose the premium and payment methods in accordance with their income for their retirement plan. The rate of Vietnamese laborers participating in VSI is low. This study aims to examine the current situation of VSI participation of laborers, as well as their perception of VSI visibility and assessment of VSI policies and utilization. Results from survey with 293 laborers, including 144 VSI participants and 149 VSI non‐participants, and semi‐structured interviews with 60 stakeholders in two districts in Northern Vietnam show the lack of awareness of VSI existence among non‐VSI participants, and limited knowledge of VSI policies among VSI participants. Although participants endorsed beneficiaries and premium in the retirement plan, they were concerned about the long 20‐year premium payment duration in the situation of unstable jobs and income, and the lack of other benefits, for example, maternity leave and unemployment benefit. Results recommend better propagandas, distributed documents, and educational sessions on VSI policies on mass and social media, as well as at VSI conferences and their workplace.     

The Effects of Sociocultural Factors on Older Asian Americans' Access to Care

Most Asian American elders are immigrants to the United States, and sociocultural factors such as English proficiency and immigration status are prominent factors in their lives. Using data from the California Health Interview Surveys to focus on Asian Americans over age 50, this study seeks to identify interethnic differences, and the effects of English proficiency and immigration status in the way older Asian Americans access healthcare. The results indicated that Asian ethnicity, English proficiency, and immigration status have significant independent effects on older Asian Americans' access to care. Implications for social work's role in addressing access disparities are discussed.
