A partial sequential design was used to study personality development over a 10-year-period. Data on the Inventory of Psychosocial Development were collected from: a sample of college students in 1966; the same sample as alumni in 1976; and a sample of undergraduates in 1976. (JMB)

Study (Lester, 1984) found that, in United States, cohorts that had high suicide rates at one point in their life span had low suicide rates at other points and vice versa, suggesting that only a limited number of people in each cohort were suicide-prone. Replicated this result using Canadian data from 1921 to present. (Author)

Argues that policymakers should be skeptical of forecasts that predict faculty shortages and surpluses according to population trends and analyzes an economic model of the academic labor market. Concludes that forecasts from such models do not support policies designed to offset the impact of cohort size on the academic labor market. (Author/CH)

Used data from 1940 through 1980 Public Use Samples of the United States Census to examine how changes in fertility patterns of women have affected age distribution of parents for successive cohorts of children. Found decline in average age of mothers and fathers across cohorts of children, partly reflecting a rapid increase in teenage pregnancies…

Research on older adults at the United Kingdom's Open University over 25 years showed that the proportion of undergraduates over 50 is 14%, over 60 is 5%; that their course choices, motivation, and study preferences differ from those of younger students; and that their achievement compares favorably with that of younger students.

This commentary details a number of problems with the study design and data analysis reported by Finkel et al. The commentary also provides suggestions for more fruitful approaches for analyzing data from such studies in the future. (Author/BC)

Explored the extent to which variations in social initiative relate to adolescents' history of interpersonal relationships. Found that positive aspects of the parent- adolescent relationship predicted adolescent social initiative 2 years later directly or indirectly. Differences in variance accounted for in two age cohorts suggested that the…

Comparison of early labor market experiences of two British cohorts born in 1958 and 1970 shows that, among the younger group, those without academic qualifications had consistently higher unemployment rates than their older counterparts who similarly lacked basic skills. Key requirements for employability have demonstrably increased over time.…

Using pooled, time-series data for a sample of 15 developed nations, we assess the effect of divorce rates on gender-specific suicide rates for youths aged 15-19 with models of relative cohort size, lagged nonmarital fertility, and an interaction term for divorce rates and nonmarital fertility. The results reveal that, for young men, relative…

Straub "et al." ("2002") recently identified the 6p22.3 gene dysbindin (DTNBP1) through positional cloning as a schizophrenia susceptibility gene. We studied a rare cohort of 102 children with onset of psychosis before age 13. Standardized ratings of early development, medication response, neuropsychological and cognitive performance, premorbid…

This pilot study presents findings from a project to evaluate a program initiated by a state child welfare agency for its most hard-to-serve youth (N = 46). This emerging population is so dangerous and unmanageable that they are difficult, if not impossible, to place or treat. One state responded to this challenge by providing exceptional care…

Genetic engineering and biotechnology made possible of gene transfer without discriminating microorganism, plant, animal or human. However, although these scientific techniques have benefits, they cause arguments because of their ethical and social impacts. The arguments about ethical ad social impacts of biotechnology made clear that not only…

Many students have difficulty when first exposed to statistical concepts. In the case of service teaching arrangements where the focus is more on the statistical literacy needs of the profession and concepts need to be developed in short time frames the challenges are even more imposing, particularly if cohorts contain substantial numbers of…

Aromaticity concept is given incorrect or incomplete to the student in secondary education and knowledge based on this basic concept has been caused to another misconception in future. How are the achievement levels relating to the comprehension of various characteristics of aromatic compounds for the first and third grade students attending…

The purpose of this study was to investigate young athletes' imagery use from a developmental perspective. The participants were 110 male and female athletes competing in both team and individual sports. They represented four different age cohorts (i.e., 7-8, 9-10, 11-12, and 13-14 years). Sixteen focus groups, two for each age category and…
