Characterising persistence of performance amongst South African general equity unit trusts

This study analyses the relative performance of general equity unit trusts from 1980 to 1999 using a database that has been verified for accuracy and is free of survivorship bias. It characterises the behaviour of performance persistence in order to explain the conflicting results of previous persistence studies.A positive but weak relationship was found between past and future performance rankings. As the holding period lengthens, the persistence results became more sensitive to the beginning date and ending date of the period under examination.Regardless of the ending date chosen, persistence of winning funds and losing funds was evident when holding periods of 6 months were used. Persistence was particularly evident during the 1995–1999 period. However, even in this period, there were situations where rankings from one holding period to the next appeared random and situations where rankings reversed.Although individual unit trusts did not perform consistently over multiple holding periods, when using a trading strategy of buying the top performing fund over the last 6 months and holding it for 6 months, it was shown that, in most cases, an investor would have earned a return over 5 years that beat the average return of all general equity unit trusts after taking switching costs into account.     

Informal mentoring and young adult employment

This study explores the role of informal mentoring (i.e., developing an important relationship with a non-parental adult) in the transition to full time employment among young adults (age 23–28). Multivariate analysis of the Add Health data reveals that mentoring is positively related to the likelihood of full time employment, and the relationship involves both selection and causation processes. Entrance into the world of work facilitates the development of mentoring relationships, especially among youth who identify work-related mentors after adolescence. These relationships have the potential for promoting attachment to the labor force. Mentoring relationships that develop outside of work settings and during adolescence have a positive impact on the odds of full time employment. The receipt of guidance and advice from mentors, as well as access to weak-tied mentoring relationships, teacher mentors, and friend mentors all contribute to the increased odds of employment in young adulthood. However, adolescent mentoring may be less effective among young women than it is among young men.     

Social Work Student Learning Experiences of Family Therapy: Improving Competency in Pedagogy Through Qualitative Research

The purpose of this qualitative study is to evaluate graduate social work student experiences of pedagogy intended to improve competency in family therapy practice. Students from two classes (N = 37) completed open‐ended surveys assessing: perceptions of most helpful pedagogical practices; understanding of needed competencies; and perceived opportunities offered to them during their graduate training for learning about work with couples and families. Results, analysed using grounded theory methodology, revealed that students: (1) believed that experiential activities were especially critical for learning how to do clinical practice with couples and families; (2) understood important competencies related to professional development, therapeutic engagement with the family, and how to approach family practice; and (3) believed they were ‘somewhat prepared’ for practice. Implications include improving understanding of abstract skills in practice with couples and families, and emphasising relationship dynamics more in graduate social work education and training.     

Poverty,Delinquency, and Educational Attainment: Cumulative Disadvantage or Disadvantage Saturation?

Data from the National Longitudinal Survey of Youth (NLSY) were analyzed to test two competing hypotheses regarding how poverty affects the relationship between delinquency and educational attainment. The cumulative-disadvantage perspective argues that poor youth suffer greater consequences for their involvement in delinquency than middle- and upper-class youth in terms of their educational attainment. Contrary to this perspective, the disadvantage-saturation thesis predicts that delinquency is less con-sequential for the educational attainment of poor youth than it is for nonpoor youth. Results from ordinary least squares and logistic regression analyses support the latter hypothesis. Theoretical and policy implications are discussed.     

Secular changes in the height of fijians and indo-fijians

Quantitative evidence is presented on secular changes in the height of adult Fijians and Indo-Fijians during the past century. Consideration is also given to changes in the tempo of maturation and in the sexual dimorphism of height of these two groups.     

Queer Blindfolding: A Case Study on Difference “Blindness” Toward Persons Who Identify as Lesbian,Gay, Bisexual,and Transgender

The purpose of this article is to introduce and explore the narrative strategy of queer blindfolding. Utilizing psycho-discursive qualitative methodology, the authors will draw from a case study to demonstrate how some beneficent, well-intended persons who identify as heterosexual adopt the narrative strategy of queer blindfolding as they negotiate the discourse of heteronormativity. We will map this narrative strategy, compare and contrast it to racial colorblindness, and unpack the accompanying intra-psychic conflict and defense mechanisms that are utilized by the participant in the case study. We will also demonstrate how this discursive strategy positions participants within systemic heterosexism.     

Obtaining Distribution Functions by Numerical Inversion of Characteristic Functions with Applications

We review and discuss numerical inversion of the characteristic function as a tool for obtaining cumulative distribution functions. With the availability of high-speed computing and symbolic computation software, the method is ideally suited for instructional purposes, particularly in the illustration of the inversion theorems covered in graduate probability courses. The method is also available as an alternative to asymptotic approximations, Monte Carlo, or bootstrap techniques when analytic expressions for the distribution function are not available. We illustrate the method with several examples, including one which is concerned with the detection of possible clusters of disease in an epidemiologic study.     

CRIMINAL OPPORTUNITY THEORY AND THE RELATIONSHIP BETWEEN POVERTY AND PROPERTY CRIME

Criminal opportunity theory suggests that community economic deprivation has two countervailing effects on property crime: it causes strain and disorganization which may encourage some individuals to offend, but it also simultaneously lessens opportunities to engage in property crime by reducing the supply of worthwhile targets in an area. The present study examines the relationship between economic deprivation and rates of burglary and motor vehicle theft for census tracts in two large American cities (Austin and Seattle). Regression analyses support the opportunity saturation hypothesis derived from criminal opportunity theory. This hypothesis suggests that the relationship between levels of deprivation and property crime is curvilinear where the positive effect of deprivation on property crime is stronger at low levels of neighborhood poverty than it is at high levels. Research and policy implications are discussed.     

Effects of Interview Mode on Assessments of Erectile and Ejaculatory Dysfunction among Men with Benign Prostatic Hyperplasia (BPH)

In a randomized experiment (N = 249; age 50 + years), this study examined if self-reports of erectile dysfunction (ED) and ejaculatory dysfunction (EjD) symptomatology were influenced by the mode of interview administration (computer-assisted self-interview [CASI], audio computer-assisted self-interview [ACASI], or computer-assisted personal interview [CAPI; involving an interviewer]). This study also examined if mode moderated person variables hypothesized to impact self-reports (social desirability, age, or depressive mood). No main or moderating effects of mode were found for self-reports of EjD symptoms. However, mode effects on reports of ED symptoms were observed, and these moderated age and social desirability effects on self-reports. Significantly more older (relative to younger) men reported high levels of ED symptoms when interview administration was by a live interviewer (CAPI) than with self-administration. Alternatively, significantly more younger men reported high levels of ED symptoms when administration was by an interviewer (CAPI) or by ACASI (vs. CASI). The Mode × Social Desirability effects were complex (see the Discussion section), showing hypothesized effects under ACASI and CAPI conditions, but an opposite effect under the CASI condition. The stability of self-reported ED symptoms did not vary by mode (based on test–retest comparisons); test–retest was significantly higher for EjD symptoms within the ACASI condition. The impact of mode of administration on self-reports of ED/EjD symptoms is less predictable and dramatic than one might conclude from prior research with other types of self-report outcomes. The findings are consistent with a small, but growing, body of studies that illustrate highly situational effects of interviewing, which may depend on a complex interplay between modes, person variables, and the interview topic/target items. Self-administered methods, in particular, may not be a universal solution to response bias.     

Perceived Admiration and Transition to Parenthood for Black and White Married Couples

Perceived admiration was examined in this study as a mediator of marital quality and transition to parenthood among Black American and White American couples. Positive and negative dimensions of marital quality were assessed for husbands (n = 148) and wives (n = 155) during their 1st and 3rd years of marriage in a large-scale survey. Findings revealed that transitioning Black American husbands reported lower marital tension than transitioning White American husbands. Perceived admiration mediated the link between transition to parenthood and marital well-being for wives, and between transition to parenthood and marital tension for husbands. Results suggest that perceived admiration plays a critical role in understanding the transition to parenthood, regardless of race. Insights are offered for practitioners who provide relationship or parental counseling and education to couples during the transition to parenthood.
