Zatsiorsky et al. (in Contemporary Problems in Biomechanics, pp. 272-291, CRC Press, Massachusetts, 1990a) obtained, by means of a gamma-ray scanning technique, the relative body segment masses, center of mass (CM) positions, and radii of gyration for samples of college-aged Caucasian males and females. Although these data are the only available and comprehensive set of inertial parameters rega...

This research asked whether performance engendered by contextual control procedures would generalize to novel matching-to-sample stimulus arrangements. Two studies were conducted with young adult participants. In Study 1, participants first were trained to perform the contextually controlled conditional discrimination, X-AB, where the sample-comparison relations A1B1 and A2B2 were reinforced in...

To better understand the social factors that influence the diverse pathways to family formation young adults experience today, this research investigates the association between opposite-gender relationships during late adolescence and union formation in early adulthood. Using data from the first and third waves of the Add Health (n = 4,911), we show that, for both men and women, there is conti...

This study tested the hypothesis that the previously reported advantage of musicians over non-musicians in understanding speech in noise arises from more efficient or robust coding of periodic voiced speech, particularly in fluctuating backgrounds. Speech intelligibility was measured in listeners with extensive musical training, and in those with very little musical training or experience, usin...

To assess Erikson's life cycle model, 86 men, initially selected for health, were prospectively studied at age 21, and reassessed 32 years later at age 53. Using the Vaillant and Milofsky (1980) modification of Erikson's model, 48 men (56%) achieved generativity, an advanced developmental stage, at follow-up. Results generally support Erikson's model and show that generativity was significantly...

The present research examined the mechanisms of initiating online gambling among young adults. Of particular interest was whether social casino gaming was noted as part of young adults' experience with online gambling. This is because there is growing concern that social casino gaming may be a 'gateway' to online gambling. Three focus groups (N = 21) were conducted with young adult online gambl...

The role of parenting styles in the development of young adult narcissism is investigated with individuals from the Block and Block (1980) longitudinal study. At age 3, participants were assessed for the presence of narcissism precursors, and mothers and fathers provided information about their parenting styles. At age 23, the presence of both healthy and maladaptive narcissism was assessed, al...

This study employs vital statistics data from Sweden, England, Wales, France, and Spain to examine male:female mortality differentials from 1750 through 2000 and their interrelationship with epidemiological transitions. Across all ages and time periods, the largest relative mortality disadvantages are to young adult men. When crisis mortality from the two world wars is removed, we show that the...

BACKGROUND/AIMS To investigate the influence of a period of sustained near work upon axial length in groups of emmetropes (EMM) and myopes. METHODS Forty young adult subjects (20 myopes and 20 emmetropes) were recruited for the study. Myopes were further classified as early onset (EOM), late onset (LOM), stable (SM) or progressing (PM) subgroups. Axial length was measured with the IOLMaster i...

An outbreak of laboratory confirmed measles involving 30 young adults and an infant is reported. Of the young adult cases, 17 (57%) were hospitalised. After a trip to India, the primary case returned to Sydney early in January 2001 and then visited Melbourne infecting several individuals. Secondary spread appears to have occurred at a nightclub. On the basis of RNA typing the measles strain inv...
