Midlife Women Online: Evaluation of an Internet-Based Program to Prevent Unintended Pregnancy & STIs

Background: Midlife women are an underserved population in the areas of unintended pregnancy and STI prevention yet remain at risk for both health conditions. Methods: A randomized controlled trial of an Internet-based multimedia program to reduce risk of unintended pregnancy and STIs among midlife women was conducted with 164 women ages 40–55 years of age. Results: Women in the treatment condition compared to the control condition reported significant gains in attitudes, self-efficacy, and behavioral intentions at posttest. Conclusion: Interventions specifically targeted to midlife women can impact constructs known to reduce risk. Implications for future research and intervention development are presented.     

Five-year-olds' Perceptions of Why We Go to School

Drawing on a recent study intended to reflect the five-olds' perspective of school this article addresses the question of ‘why we go to school’. Fifty children from five county council reception/year one classrooms were observed and then interviewed over a ten-week period. There occurs a socialisation of these children to the view that schooling is essential for their preparation for the future. According to the children this takes place during activities identified as ‘work’ not ‘play’ and is emphasised by the compulsory nature of schooling.     

A Simulation Model for Occupational Tuberculosis Transmission

A simulation model of tuberculosis (TB) transmission among hospital employees is described. A hypothetical cohort of 1000 workers was divided into low-, medium-, and high-risk groups. The number of TB patients admitted daily was treated as a Poisson random variable. A patient imparted a daily infection risk that was identical for all workers within a risk group but that varied between risk groups. In some scenarios, infected employees were assigned a daily risk of developing TB disease. If disease developed, the individual remained on the job for 3 calendar weeks and imparted a substantial infection risk to 25 close contacts. Simulations were run over 5-year intervals. Cumulative infection incidence increased over time and with more TB patients admitted. Given a scenario in which there were 600, 300, and 100 susceptibles in the low-, medium-, and high risk groups, respectively, 50 TB patients admitted annually and accounting for disease among infected employees, at 5 years there were approximately 100 primary infections (due to infection by patients), 40 secondary infections (due to infection by diseased coworkers), five primary disease cases, and two secondary disease cases. The input parameter values and simulation outcomes were reasonably consistent with the sparse information reported in the literature.

The effect of the board and executive committee characteristics on the degree of internationalization

Many corporate governance observers agree that when firms encounter dramatically changed competitive environments, the board of directors may become involved in the strategy formation process. Based on Finkelstein and Hambrick’s (Finkelstein, S., Hambrick, D., 1996. Strategic leadership: top executives and their effects on organizations. West, Minneapolis, MN.) conceptual model, we examine the effects of the board of directors and executive committee characteristics on the degree of internationalization of the U.S. telecommunications industry during the 12 years after AT&T’s 1984 divestiture. We also examine the effects of the regulatory environment and core business growth on the degree on internationalization during this time. We find support linking executive committee characteristics and regulatory environment to the degree of internationalization. Characteristics of the entire board are consistently found to be insignificant.     

Mesothelioma Among Brake Mechanics: An Expanded Analysis of a Case-Control Study

The U.S. Environmental Protection Agency has begun discussions to consider its assessment of asbestos toxicity related to mineral form and fiber size. Brake workers are typically exposed to short chrysotile fibers. To explore the mesothelioma risk among brake workers, considering other occupational exposures to asbestos, data from a study that was published previously were obtained and the analysis was extended. The National Cancer Institute provided data from a case-control study of mesothelioma. Because many participants with a history of brake work also had employment in other asbestos-related occupations, mesothelioma cases and controls were compared for a history of brake work, controlling for employment in eight occupations with potential asbestos exposure. A stratified analysis was also performed excluding those with any of the eight occupations. Possible interactions between brake work and other occupational exposures related to risk of mesothelioma were also examined. The odds ratio (OR) for employment in brake installation or repair was 0.71 (95% CI: 0.30-1.60) when controlled for insulation or shipbuilding. When a history of employment in any of the eight occupations with potential asbestos exposure was controlled, the OR was 0.82 (95% CI: 0.36-1.80). ORs did not increase with increasing duration of brake work. Exclusion of those with any of the eight exposures resulted in an OR of 0.62 (95% CI: 0.01-4.71) for occupational brake work. There was no evidence of an interaction between brake work and other occupational exposures. These latter analyses were based on small numbers of exposed cases. The results are consistent with the existing literature indicating that brake work does not increase the risk of mesothelioma and adds to the evidence that fiber type and size are important determinants of mesothelioma risk.     

Targeting Democracies: Regime Type and America's "Aggressively Unilateral" Trade Policy

Objectives . The American trade policy instrument Section 301 authorizes the president to demand changes in foreign states' trade policies and to fortify these demands with threats of sanctions. I examine the economic and political factors that influence the selection of states as targets for Section 301 proceedings. Methods . I develop an argument connecting a state's regime type to the likelihood that it will be targeted under Section 301. Controlling for other relevant factors, democratic states are predicted to have a higher probability of being targeted. I test the hypothesis in a set of regression models on cross–sectional time series data with both targeting incidence and targeting frequency as dependent variables. Results . States with more open and competitive political systems are more likely to be targeted under Section 301. Of the included variables, only a state's regime type and the size of its trade relationship with the United States have consistently significant effects across alternative model specifications. Conclusions . Section 301 plays on the rivalry between protectionist and export–oriented interests by demanding reductions in trade barriers and backing them up with threats directed against export industries. Industries currently favored by protectionist policies have a higher chance of losing such a political contest in a political system more open to interest–group competition. The institutional form of political competition within a state affects the state's response to international pressure on trade policy.
