The categorical versus dimensional assessment controversy in the sociology of mental illness

This paper reviews the sociological controversy over using categorical versus dimensional assessments in the study of psychological distress. The preference of sociologists for dimensional assessments is traced to two assumptions: (1) that the associations of predictors with psychological distress syndromes are most accurately operationalized by using dimensional measures; and (2) that no true discrete mental illnesses can reasonably be inferred to exist that would justify the creation of dichotomous measures. Methods are described in this paper to test both assumptions. An argument is made that the first assumption is the critical one and that dimensional analysis is useful only when it can be demonstrated that the associations of predictors with dimensional scores are constant throughout the relevant dimensional severity range. The paper closes with an argument for the tandem use of categorical and dimensional assessments in future sociological research.     

Prevention efforts underlying decreases in binge drinking at institutions of higher education

Analyses of 94 Fund for the Improvement of Post-Secondary Education (FIPSE)-sponsored drug-prevention programs and their outcomes used the Core Survey to identify 34 institutions where college students' binge drinking increased (M = 5.44%) and 60 institutions where it decreased (M = -4.59%) during 2 years of program operation. The authors used an inductively derived taxonomy of prevention program elements, student variables, student substance use, use-related variables, and institutional variables to compare the 2 groups of institutions. Only prevention program elements discriminated between groups. Factor analysis of discriminating elements identified 8 prevention factors that improved base-rate prediction of institutional decrease in binge drinking by 28.1%. Factor synthesis yielded a 3-construct binge-drinking prevention model based on student participation and involvement strategies, educational and informational processes, and campus regulatory and physical change efforts. This model improved base-rate prediction of decreased binge drinking by 33.2%.     

Patterns of Work and Schooling in Young Adulthood

If the years of late adolescence and early adulthood are depicted as rocky, disorderly, and experimental, then how should the life course stage that immediately follows be characterized? Using data from the National Longitudinal Study of the High School Class of 1972, we focus on work and school activities in the latter half of the young adult years (ages roughly 25–31) to empirically address whether the diversity of work and schooling patterns diminishes. Finding a lack of orderliness in work and schooling trajectories, and that holding two or more activities simultaneously is quite common, we question how this stage of the life course should be conceptualized. Moving away from the traditional sequential roles approach, we use multinomial logistic regression to differentiate among activity sequences commonly held by young men and women at these ages, and address how family of origin background factors and prior life experiences influence life course experiences in the later 20s and early 30s.

     

Three Critical Characteristics of Leadership: Character,Stewardship, Experience

There is no one definition of leadership. The leadership equation is never set or fixed. Time, place, specific problems, the particular parties involved all play a role in the leadership equation. Nor is there one specific list of attributes, virtues, or skills that all leaders must and do possess. Nonetheless, we argue that at its core, all forms of ethical leadership are based on three elemental ingredients: character, stewardship, and experience.     

HIV diffusion patterns and mobility: Gender differences among drug users

Researchers have recently expanded the scope of study of transmission patterns of AIDS to incorporate spatial and geographical questions. United States diffusion patterns of this disease appear to indicate that it may emanate from urban area epicenters to areas of low and moderate prevalence. The travel patterns of injecting drug users (IDUs) and the extent to which they engage in high risk drug and sexual activities was examined as an explanation of diffusion of the HIV virus from one community to another. The study population of 49,621 was comprised of subjects recruited from approximately 60 sites nationwide from 1988–1991. While the data are limited in some ways, they partially support a diffusion explanation of HIV transmission for males and females. The analysis demonstrates that low prevalence cities were significantly more likely to have been the destinations of both men and women who engaged in high risk drug and sexual activities. In addition, HIV seropositive drug users who engaged in high risk drug and sexual behaviors in destination cities were more likely than seronegatives to travel to high or low seroprevalence areas than to moderate prevalence areas. The findings suggest a need for effective HIV prevention educational messages about the risks of traveling and participating in high risk activities.     

Community and contraceptive choice in rural Thailand: A case study of Nang Rong

This paper blends quantitative with qualitative data in an investigation of community and contraceptive choice in Nang Rong, Thailand. Specifically, it develops an explanation of 1) method dominance within villages, coupled with 2) marked differences between villages in the popularity of particular methods. The quantitative analysis demonstrates the importance of village location and placement of family planning services for patterns of contraceptive choice. The qualitative data provide a complementary perspective, emphasizing the importance of social as well as physical space and giving particular attention to the structure of conversational networks.     

The initiation of contraception

Using data from the 1970 National Fertility Study, the trend in the initiation of contraception prior to the first pregnancy is examined. This trend is of interest because of its relationship to the tempo of familybuilding. Using data from a recent marriage cohort, it is shown that use before the first pregnancy is related to age at marriage, age at termination of first pregnancy and the probability of having a premarital conception. For women first married during the decade of the 1960’s, there was a substantial increase in the proportion using contraception before the first pregnancy. This trend is found among both white Catholics and white non-Catholics, but not among blacks. An examination of the specific method used by women using contraception before the first pregnancy reveals a shift from reliance on the traditional methods of diaphragm, condom and douche by the earlier birth cohorts to the use of the pill by the more recent cohorts. An appendix examines the reliability of various measures of the interval of first use of contraception.     

Changes in fertility expectations and preferences between 1962 and 1977: Their relation to final parity

Changing fertility expectations and preferences from 1962 to 1977 are compared with final parity in a longitudinal study. Results are strongly affected by initial parity in 1962. Final parity, 27 percent below expectations for those initially childless, illustrates the effect for couples free to change expectations downward of declining fertility preferences. Changes in expectations early in marriage had a significant long-term effect on final parity, as did early differences between wife’s expectations and husband’s preferences. Unplanned births increased final parity significantly. Religion, education, and income had no systematic relation to the discrepancy between initial expectations and final parity.     

Parental care and EGG size in salamanders: An examination of the safe harbor hypothesis

Summary The safe harbor hypothesis includes the suggestion that parental care causes the embryonic stage to be the safest harbor, and, therefore, egg size will increase in populations with parental care to decrease the duration of subsequent, higher risk stages. Neither the safe habor hypothesis nor r and K theory seem adequate to explain the correlation between egg size and the presence/absence of parental care among salamanders, a group in which there is a further correlation between the larval (hatchling) habitat and egg size/parental care. Pond-breeding salamanders generally have small eggs and lack parental care, and stream-breeding salamanders generally have large eggs and parental care. I argue that the fundamental difference in the food available to hatchling salamanders between lentic (plankton-rich) and lotic (plankton-poor) environments selects for relatively lower parental investment in the lentic environment. From the standpoint of parental fitness, small (more numerous) hatchlings have a greater payoff where the available food is mall and dense (zooplankton in lentic environments), and large hatchlings are selectively advantageous where the food is of large size and less dense (benthic invertebrates in lotic environments). Selection for larger hatchlings in lotic environments results in longer embryonic periods and,ceteris paribus, greater total embryonic mortality. Embryo hiding and guarding have evolved among lotic-breeding salamanders as compensatory mechanisms to reduce the rate of embryonic mortality. In this view, parental care is a consequence of selection for larger egg size and not an umbrella that allows egg size to increase, contrary to the safe harbor hypothesis. The relationship between variance in parental investment and food available to offspring, developed here for salamanders, may be of general significance. YosiakiIt?, a critic of r and K theory, independently arrived at a similar conclusion from a broader data base.
