Sexual orientation of human offspring may be altered by severe maternal stress during pregnancy

To test the hypotheses that maternal stress during pregnancy may alter the sexual orientation of offspring, 285 women with offspring 19 years of age and older provided retrospective accounts of stressful experiences they had, beginning 12 months prior to pregnancy up to the point of giving birth, and indicated how severe they recalled each event being. When weighted according to severity, stressful experiences helped to predict sexual orientation of male offspring. While most of the variance in sexual orientation remained unexplained, the data suggest that the most critical time in gestation for influencing human sexual orientation of male offspring is during the second trimester, although the first and possibly the third trimesters may be of secondary importance. For female offspring, no significant relationships between maternal stress and sexual orientation were found, although mothers of lesbians did report slightly higher average levels of stress throughout gestation than mothers of female heterosexuals.     

Sociology in the high school: Perceptions of those who teach it

The following research note reports two major findings of a more detailed study of the opinions, training, and practices of teachers of high school sociology in Texas. Two major findings of interest to the discipline emerge from the research: (1) high school teachers are only marginally prepared in the field of sociology itself; (2) teachers generally give sociology's reputation as a discipline a favorable rating, while at the same time showing concerns about whether or not they would recommend sociology as a college major. The implications of teacher attitudes and training for the discipline are explored.     

Did the Military Interventions in the Mexican Drug War Increase Violence?

We analyze publicly available data to estimate the causal effects of military interventions on the homicide rates in certain problematic regions in Mexico. We use the Rubin causal model to compare the post-intervention homicide rate in each intervened region to the hypothetical homicide rate for that same year had the military intervention not taken place. Because the effect of a military intervention is not confined to the municipality subject to the intervention, a nonstandard definition of units is necessary to estimate the causal effect of the intervention under the standard no-interference assumption of stable-unit treatment value assumption (SUTVA). Donor pools are created for each missing potential outcome under no intervention, thereby allowing for the estimation of unit-level causal effects. A multiple imputation approach accounts for uncertainty about the missing potential outcomes.     

Diversity training pitfalls and possibilities: An exploration of small and mid-size US organizations

Abstract

This qualitative, exploratory study examines the development and implementation of diversity training in small and mid-size organizations in a Midwestern region of the United States. The results are contrasted with diversity best practices and found lacking in key elements identified as most likely to yield success. Specifically, the organizations in this study did not provide training beyond awareness level, failed to conduct front-end needs assessment, provided little if any in-depth evaluation of diversity training and showed varying support for diversity endeavors from the leadership and through connecting diversity training with other systemic initiatives. The article concludes with recommendations for additional exploration of adapting effective diversity training practices to minimize pitfalls and maximize possibilities in small and mid-size systems.     

Fishermens blues: Factors related to accidents and safety among Newfoundland fishermen

Abstract

The fisheries is one of the most dangerous industries in Canada. Possible contributory causes of the high rate of injuries are a fatalistic attitude to accidents and safety, and a high level of anxiety and worry among fishermen. These characteristics would be expected to lead to less attention to safety procedures and a consequent greater risk of accidents. The purpose of this study was to explore fishermen's levels of fatalism and anxiety; to consider the relationship of these factors to the frequency of accidents and extent of safety precautions; and to explore fishermen's explanations of and suggested solutions to the high rate of injuries at sea. The study was conducted among a sample of inshore fishermen who fished in the waters around Newfoundland. Fifty-five fishermen completed a questionnaire that requested basic demographic details, information on injuries obtained, safety precautions taken, perceived locus of control over accidents, anxiety, worries and explanations for accidents and possible measures to reduce them. Analysis of their replies revealed that the fishermen reported a high level of anxiety and that those who reported most anxiety reported more injuries and fewer safety precautions.     

SELF-CONCEPT AS THE ORGANIZATION OF ROLES: Importance, Centrality, and Balance

Data from a set of middle-aged working men and women from the Raleigh-Durham-Chapel Hill metropolitan area are used to explore three different ways that individuals organize their self-concepts and infuse personal significance into their roles. Five sets of findings include the following: (1) both men and women identify many of their roles as personally significant, especially work and family roles; (2) men tend to attribute more importance and centrality to the role of worker than do women, while women tend to assign greater importance and centrality to most other roles; (3) different combinations of importance, centrality, and balance influence worker, spouse, and parent role satisfaction and identity meanings; (4) worker role centrality tends to have negative effects on spouse and parent role satisfaction and identity meanings; and (5) worker role importance and spouse centrality have a positive influence on self-esteem while worker centrality has a negative impact on self-esteem. The findings suggest that importance, centrality, and balance appear to be independent dimensions of personal significance that individuals ascribe to their roles.

Determination of an Occupational Exposure Guideline for Manganese Using the Benchmark Method

An occupational risk assessment for manganese (Mn) was performed based on benchmark dose analysis of data from two epidemiological studies providing dose-response information regarding the potential neurological effects of exposure to airborne Mn below the current Occupational Safety and Health Administration (OSHA) Permissible Exposure Level (PEL) of 5 mg Mn/m3. Based on a review of the scientific evidence regarding the toxicity of Mn, it was determined that the most appropriate measure of exposure to airborne Mn for the subclinical effects measured in these studies is recent (rather than historical or cumulative) concentration of Mn in respirable (rather than total) particulate. For each of the studies analyzed, the individual exposure and response data from the original study had been made available by the investigators. From these two studies benchmark concentrations calculated for eight endpoints ranged from 0.09 to 0.27 mg Mn/m3. From our evaluation of these results, and considering the fact that the subtle, subclinical effects represented by the neurological endpoints tested in these studies do not represent material impairment, we believe an appropriate occupational exposure guideline for manganese would be in the range of 0.1 to 0.3 mg Mn/m3, based on the respirable particulate fraction only, and expressed as an 8-hour time-weighted average.
