Inverse Circular–Linear/Linear–Circular Regression

We propose two distance-based methods and two likelihood-based methods of inversely regressing a linear predictor on a circular variable, and of inversely regressing a circular predictor on a linear variable. An asymptotic result on least circular distance estimators is provided in the Appendix. We present likelihood-based methods for symmetrical and asymmetrical errors in each situation. The utility of our methodology in each situation is illustrated by applying it to real data sets in engineering and environmental science. We then compare their performances using a cross validation method.     

Best Linear Classification Rule for Multivariate Interval Screened Data

In classification analysis, the target variable is often in practice defined by an underlying multivariate interval screening scheme. This engenders the problem of properly characterizing the screened populations as well as that of obtaining a classification procedure. Such problems paved the way for the development of yet another linear classification procedure and the incorporation of a class of skew-elliptical distributions for describing evolutions in the populations. To render the linear procedure effective, this article considers derivation and properties of the classification procedure as well as efficient estimation. The procedure is illustrated in applications to real and simulation data.     

The experience of rural midwives in dual roles as nurse and midwife: “I’d prefer midwifery but I chose to live here”

ObjectiveTo explore and describe the experiences of working in the dual role as nurse and midwife in rural areas of far north Queensland, Australia.MethodThe methodology was informed by Heidegger's interpretive phenomenological philosophy and data analysis was guided by van Manen's analytical approach. Data was generated by conversational interviews. Eight midwives working in a dual role as midwife and nurse were interviewed individually.FindingsThree themes were identified: Making choices between professional role and lifestyle: “Because I choose to live here”; Integration of maternity and general nursing: “All in together this fine weather” and: “That's part of working in a small place”.ConclusionParticipants recognized that in rural areas it is important to be a multi-skilled generalist; however they were concerned that midwifery skills could be eroded or even lost with the diminishing amounts of midwifery work available. Appropriate re-structuring of maternity services could provide better use of the midwifery workforce in rural centres, and reduce the current problems associated with transferring birthing mothers to larger facilities. Further research is needed to examine the extent to which the requirement to work in a dual, or multifaceted role is an impediment to the recruitment and retention of midwives to rural areas.     

The Socioeconomic Attainments of Non-immigrant Cambodian, Filipino, Hmong, Laotian, Thai, and Vietnamese Americans

Using recent American Community Survey data, this study investigates socioeconomic attainments of six ethnic groups of Southeast Asian Americans. Findings show that the educational attainment of Filipinos, Vietnamese, and Thai is higher than that of whites, while the educational attainment of Cambodians, Hmong, and Laotians is lower than that of whites. Regarding earnings, Southeast Asian American women are generally not disadvantaged relative to white women, but Southeast Asian American men tend to have lower earnings than white men after controlling for education and other demographic factors such as age, metropolitan residence, and region. We conclude that Cambodians, Hmong, and Laotians are the most disadvantaged groups among Southeast Asian Americans and that most Southeast Asian American male groups tend to be at least slightly disadvantaged in the labor market at least after controlling for metropolitan residence and region.     

The same but different: HRD master’s programmes in the United States

In this study, we examined the curricular and institutional characteristics of HRD master’s programmes in the United States. Our sample included 108 programmes in 100 institutions that were self-identified as HRD programmes. Among our findings: (1) fewer programmes were located in schools of education (44%) and more were located in schools of business (28%) than indicated by previous research; (2) there was greater homogeneity in curriculum among programmes in the same institutional locations (e.g. schools of education or schools of business) and greater variation among programmes in different institutional locations; (3) the curriculum of programmes located in schools of education tended to focus on traditional educational topics such as adult learning and instructional design, while the curriculum of programmes located in school of business tended to focus on management topics such as organization development, staffing and employment law. Our findings suggest that the nature of HRD as an academic subject varies with institutional location, as do the skill sets of students who graduate from HRD programmes. Future research should take these differences into account.     

Taipei,Taiwan: A transformational learning event: Reflecting on the 4th Asian Conference of Academy of Human Resource Development

Abstract

The 4th Asian Conference of the Academy of Human Resource Development held in Taipei, Taiwan, nurtured new learning, networking and international integration. As we reflected upon the experience in Taiwan, the realization was evident that we now view the world from a global perspective. We no longer look at the world through our own country's lenses. Through participation in this transformational learning event, the way we see the world and ourselves has changed as well as enriched our HRD knowledge.     

Parametric estimation of association in bivariate failure-time data subject to competing risks: sensitivity to underlying assumptions

Lifetime Data Analysis - There has arisen a considerable body of research addressing the estimation of association between paired failure times in the presence of competing risks. In a 2002 paper,...
