Academic Self-Efficacy,Dropping Out,and the Significance of Inequality

Increased academic self-efficacy can facilitate educational progress and success as well as minimize the risk of dropping out for adolescents. However, there are sex, racial, and ethnic disparities associated with the risk of dropping out of high school. What remains unknown is if increased academic self-efficacy can minimize sex, racial, and ethnic disparities linked to the risk of adolescents dropping out. This study utilizes data from the Education Longitudinal Study of 2002 and incorporates multilevel modeling techniques to examine the impact of academic self-efficacy on dropping out. The results indicate that racial and ethnic minorities have relatively lower levels of academic self-efficacy; however, increased academic self-efficacy can ameliorate sex, racial, and ethnic dropout disparities. The implications of the evident sex, racial, and ethnic disparities in the relationship between academic self-efficacy and dropping out are discussed.     

Treating Problem Gamblers: Working towards Empirically Supported Treatment

There is an urgent need for mental health professionals to develop effective treatments for pathological gambling. A scientific meeting was held in Quebec City in June 2002 where 13 specialists in the treatment of gamblers pursued the objectives of making the State of the art statement concerning the procedures and the methodology to be used in future treatment outcome studies. This paper introduces this special issue of the Journal of Gambling Studies and identifies some of the key issues that confront clinicians and researchers interested in evidence based treatment for gambling related disorders.     

Awareness of Gambling-Related Problems, Policies and Educational Programs Among High School and College Administrators

This brief report summarizes a survey of high school and college representatives and their awareness toward gambling-related problems. The Massachusetts Council on Compulsive Gambling developed a survey instrument to review the policies and training programs of 20 high schools and 10 colleges that were located within the catchment areas of Massachusetts Department of Public Health state-sponsored gambling treatment programs. The results revealed that there is an important discrepancy between the prevalence of gambling-related problems among young people and the awareness of these problems among educators. High school and colleges evidence a paucity of existing gambling-related regulations or policies. There is little opportunity for students and educators to learn within the school setting about gambling and its potential hazards. Without sufficient in-service education and training for faculty and staff, there is little likelihood that this group of educators can engage in the early identification or prevention efforts that are so vital to advancing the health and welfare of young people.     

Normative advice to campus crime victims: effects of gender, age, and alcohol

Three studies investigated the appropriateness of calling the police as a function of crime, victim, and subject factors. In particular, the studies focused on whether and how the victim's consumption of alcohol affected normative advice to report the crime, as opposed to other options. Across the three studies, subjects viewed reporting as more appropriate for female victims, for victims who were 21 or older, and for victims who had not been drinking. In addition, females were more likely than males to believe reporting to the police was appropriate whereas males were more likely than females to favor some type of private action. Subjects viewed reporting as particularly inappropriate when the victim was underage and had been drinking. Results suggest that, because of the perceived stigma attached to victims who have been drinking, even serious victimizations may go unreported.     

Missouri Casino Self-Excluders: Distributions Across Time and Space

According to public health research, exposure to casinos is a risk factor for disordered gambling. Consequently, casino self-exclusion programs, which provide gamblers with the opportunity to voluntarily seek limits on their access to gambling venues, can serve as a barometer of the concentration of disordered gambling in an area. This study reports on the distribution, both temporally and geographically, of 6,599 people who applied to exclude themselves from Missouri casinos between November, 1996 and February, 2004. Analyses used Microsoft MapPoint to plot the location of casinos and self-excluders (SEs) across Missouri and its constituent counties. These regional exposure analyses showed that the Western region around Kansas City is an epicenter of disordered gambling as, to a lesser extent, is the Eastern region around St. Louis. The annual number of SE enrollments increased during the first few years of the Missouri self-exclusion program and then leveled off during the later years. These findings have important implications for public health and the development of public health interventions for disordered gamblers.     

Rewards and Costs in Adolescent Other-sex Friendships: Comparisons to Same-sex Friendships and Romantic Relationships

This study used a social exchange framework to examine the features of non-romantic other-sex (OS) friendships compared with same-sex (SS) friendships and romantic relationships. High school seniors (N  =  141) completed open-ended interviews about the benefits and costs of having OS friendships, SS friendships, and romantic relationships in general. As expected, perspective taking, learning about the other sex, and meeting the other sex were seen as rewards of OS friendships more often than for SS friendships and romantic relationships. Confusion about the nature of the relationship was seen as a cost of OS friendships more often than of SS friendships and romantic relationships. Intimacy, support, and companionship were mentioned less often as rewards of OS friendships than romantic relationships. Adolescents also completed questionnaires about their own specific relationships of each type. Their OS friendships were perceived as less supportive than their other two relationships; OS friendships were also seen as having fewer negative interactions than romantic relationships. Our findings expand the application of social exchange theory and lend empirical support to prior speculations about OS friendships and their importance in adolescents' social worlds.     

How a Navigation Channel Contributed to Most of the Flooding of New Orleans During Hurricane Katrina

Levee failures during Hurricane Katrina left 85% of New Orleans flooded, 1,500 dead, and about 400,000 homeless. Three separate investigations into the levee failures have been concluded, yet none of these studies conclusively determined why the St Bernard polder flooded so deeply, despite Team Louisiana’s conclusion regarding early failure of the Mississippi River Gulf Outlet (MRGO) levees. Detailed wave and hydrodynamic modeling reported here reveals the cause of extensive breaching of the MRGO levees and how that created a very efficient conduit of surge water into the heart of the city.     

Validation and Application of Models to Predict Facemask Influenza Contamination in Healthcare Settings

Facemasks are part of the hierarchy of interventions used to reduce the transmission of respiratory pathogens by providing a barrier. Two types of facemasks used by healthcare workers are N95 filtering facepiece respirators (FFRs) and surgical masks (SMs). These can become contaminated with respiratory pathogens during use, thus serving as potential sources for transmission. However, because of the lack of field studies, the hazard associated with pathogen‐exposed facemasks is unknown. A mathematical model was used to calculate the potential influenza contamination of facemasks from aerosol sources in various exposure scenarios. The aerosol model was validated with data from previous laboratory studies using facemasks mounted on headforms in a simulated healthcare room. The model was then used to estimate facemask contamination levels in three scenarios generated with input parameters from the literature. A second model estimated facemask contamination from a cough. It was determined that contamination levels from a single cough (≈19 viruses) were much less than likely levels from aerosols (4,473 viruses on FFRs and 3,476 viruses on SMs). For aerosol contamination, a range of input values from the literature resulted in wide variation in estimated facemask contamination levels (13–202,549 viruses), depending on the values selected. Overall, these models and estimates for facemask contamination levels can be used to inform infection control practice and research related to the development of better facemasks, to characterize airborne contamination levels, and to assist in assessment of risk from reaerosolization and fomite transfer because of handling and reuse of contaminated facemasks.
