Lynn [Lynn, R., 2002. Sex differences on the progressive matrices among 15-16 year olds: some data from South Africa. "Personality and Individual Differences 33," 669-673.] proposed that biologically based developmental sex differences produce different IQ trajectories across childhood and adolescence. To test this theory we analyzed the…

This study examined whether the structural attributes of a formal mentoring program and/or certain demographic characteristics of participants in the program influence protege satisfaction. Proteges, employed in a traditionally male occupation, were sampled from a federal agency's mentoring program. According to policy, the agency attempted to…

The "productivity puzzle," or gender gap in research productivity, is often thought to be due, in part, to gendered child care responsibilities. The time, energy, and money devoted to child-rearing can reduce the research productivity of scholars, especially women. However, there is little systematic research on this issue. The present study…

In this study, we use data from the 1999 National Study of Postsecondary Faculty (NSOPF:99) to measure the unexplained wage gap between men and women in academe. We pay particular attention to how these unexplained wage gaps have changed over time by comparing the results from the 1999 survey to published results from previous national surveys and…

This study uses data from the 1999 National Study of Postsecondary Faculty to examine the ways in which parental status, marital status, and employment status of the spouse are related to two outcomes, tenure and promotion, among college and university faculty. The analyses are guided by a conceptual model that draws upon the economic theory of…

Some researchers believe that important tenets of attachment theory are culturally universal, whereas others claim that key constructs are rooted in Western values and should not be generalized further. To explore possible cultural differences in adults, undergraduates from Taiwan (n = 280) and the United States (n = 268) were asked in the present…

Anchored in national longitudinal data analyzed through hierarchical linear and non-linear modeling, this study found that African-American students have a similar probability of obtaining a BA degree whether they attended a historically Black college or university (HBCU) or a historically White college or university (HWCU). Among…

The ingredients that underpin economic growth are well-known and generally accepted; population growth, physical capital, financial capital and human capital all play a part in creating long term differences in the wealth of nations. There remains, however, considerable debate about the ideal recipe for economic growth. Recently, Statistics Canada…

A total of 378 Hong Kong adolescents estimated their own and their parents' IQ score on each of Gardner's 10 multiple intelligences: verbal (linguistic), logical (mathematical), spatial, musical, body-kinesthetic, interpersonal, intrapersonal, existential, spiritual and naturalistic. They answered three simple questions concerning intelligence and…

This study examined the acoustic characteristics of vowels produced by speakers with partial glossectomy. Acoustic variables investigated included first formant (F1) frequency, second formant (F2) frequency, F1 range, F2 range and vowel space area. Data from the speakers with partial glossectomy were compared with age- and gender-matched controls.…

We examined leisure behaviours and the relationships between leisure and a variety of problem behaviours in a sample of 1422 Hungarian adolescents (age range: 14-19). Findings from multivariate analyses suggest that some aspects of adolescent leisure, such as family or conventional activities, act as protective factors against problem behaviours,…

The prevalence of psychiatric disorders among incarcerated juveniles in Mississippi was examined. A total of 482 adolescents completed a diagnostic questionnaire and a subset (N = 317) was assessed with face-to-face semistructured interview. Most of the study participants met criteria for one mental disorder, 71?85% depending on assessment method,…

Sex differences in the etiology of normal cognitive functioning in aging remain largely unexplored. We conducted an investigation of genetic and environmental contributions to sex differences in level of cognitive performance and rate of decline in the Swedish Adoption/Twin Study of Aging (SATSA) (Finkel & Pedersen, 2004) data set. Behavioral…
