Urban areas may serve as habitat and corridors for dry-adapted,heat tolerant species; an example from ants

We collected ants from six urban and one forest land-use types in Raleigh, NC to examine the effects of urbanization on species richness and assemblage composition. Since urban areas are warmer (i.e., heat island effect) we also tested if cities were inhabited by species from warmer/drier environments. Species richness was lower in industrial areas relative to other urban and natural environments. There are two distinct ant assemblages; 1) areas with thick canopy cover, and 2) more disturbed open urban areas. Native ant assemblages in open environments have more southwestern (i.e., warmer/drier) distributions than forest assemblages. High native species richness suggests that urban environments may allow species to persist that are disappearing from natural habitat fragments. The subset of species adapted to warmer/drier environments indicates that urban areas may facilitate the movement of some species. This suggests that urban adapted ants may be particularly successful at tracking future climate change.     

Perceived continuing education needs and job relevance of health education competencies among health education and promotion practitioners in college health settings

Objective and Participants: The author conducted this study to determine college health education and promotion practitioners' perceived continuing education needs and perceived job relevance in relation to national health education responsibilities and competencies. Methods: In Spring 2006, the author invited college health education and promotion professionals to participate in an online survey, using 3 listservs. Of 276 individuals visiting the Web site, 141 participants completed the survey (51%). Participants rated their perceived training needs and job relevance for the 35 National Commission for Health Education Credentialing (NCHEC) competencies as well as preferred training formats. Results: Participants identified the following competencies as those in which they needed additional training: designing data-collection instruments, securing fiscal resources, interpreting evaluation and research results, carrying out evaluation and research plans, and developing plans for evaluation and research. They identified the following competencies as being the most relevant to their jobs: demonstrating a variety of skills in delivering strategies, interventions, and programs; using a variety of methods to implement strategies, interventions, and programs; initiating a plan of action; and using health-related information resources. The most preferred methods of obtaining additional continuing education were attending the American College Health Association annual meeting (67%) and completing home self-study print materials (67%). Conclusions: Collegiate professional organizations should offer a variety of continuing education opportunities centering on NCHEC competencies, specifically those perceived as needed by study participants.     

Beliefs of Guilt and Recommended Sentence as a Function of Juror Bias in the O. J. Simpson Trial

During the week of April 9, 1995, 125 male participants completed a questionnaire assessing attitudes toward the O. J. Simpson trial. Specifically, participants reported their belief in the defendant's guilt or innocence, stated how fair they perceived the trial to be, and recommended a sentence should the defendant be found guilty of the crime. Additionally, participants completed Kassin and Wrightsman's Juror Bias Scale and the revised California F scale. Overall, results showed that participants' scores on both scales were positively correlated with their beliefs in the defendant's guilt, perceived trial fairness, and more severe sentence recommendations.     

Social Construction and Policy Implementation: Inmate Health as a Public Health Issue*

Objectives. This article develops and tests a concise multi‐stage approach for assessing the impact of social construction on the implementation of public programs designed to benefit negatively constructed groups. The framework suggests that negative constructions lead to policy choices that create problems in the implementation process. These problems prevent the accomplishment of key subobjectives necessary for ultimate program success. Methods. We test the utility of the framework in an analysis of a key public health issue—the spread of HIV/AIDS and tuberculosis in prisons. Despite great strides in the treatment and prevention of these diseases outside prison walls, the incidence and severity of both in the incarcerated population has increased dramatically over the last five years. We hypothesize that the problem of inadequate funding, arising from the negative social construction of this unique target population, is to blame. Results. In an analysis of 50 state correctional systems, we find that states with the most negative constructions of criminals and potential criminals spend dramatically less on inmate health, relative to other states. Conclusions. Our analysis suggests that inadequate funding levels in states with negative constructions of criminals and potential criminals jeopardizes the implementation of prison programs targeted at the prevention and treatment of HIV/AIDS and tuberculosis.     

Skewness-Kurtosis Bounds for EGB1, EGB2, and Special Cases

An examination of the theoretical moments of a probability density function provides useful information about the flexibility of alternative distributions. Johnson and Kotz (1970), among others, consider skewness-kurtosis plots to illustratve the ability of various probability density functions to model diverse distributional characteristics. This article investigates the skewness-kurtosis plots of the exponential generalized beta of the first and second kind and some important special cases which have been used in various applications in economics, statistics, and finance.     

Assessing Observer Effects on the Fidelity of Implementation of Functional Analysis Procedures

Instructing and training others to implement functional analysis (FA) procedures can be a cumbersome and time-consuming task. Students and practitioners are required to learn all of the various components to establish conditions and analyze results while also learning to conduct the sessions. The current study assessed the fidelity of individuals implementing FA conditions after observing and rating the fidelity of videos models, using a multiple-baseline design across FA conditions. Video models of each condition were provided throughout; however, participants were only asked to provide fidelity ratings for one video. Results demonstrated the intervention was successful in increasing participant performance above baseline levels for 16 of 17 participants, with 7 participants requiring an additional intervention in which they were asked to observe their own performance. Further research should evaluate the degree to which this procedure may effectively prepare individuals working with non-confederate children and carry over to other responses and settings.     

Cultural influences on parental bereavement in Chinese families

The purpose of this study was to explore the bereavement experiences of parents who had experienced the death of a child in Chinese families. In-depth interviews were conducted with 10 bereaved parents in Macau, China. Narrative accounts of Chinese parents' experience in the loss of a child were explored to understand how their connection to the deceased child and their worldview were influenced by cultural beliefs and values. Study themes related to parental connections with the deceased child included the use of object linking, memorializing acts, and avoidance of traditional funeral processes, with clear patterns of Chinese cultural influence. Additionally, themes related to impacts on parental worldview included use of the concept of fate as a rationale for child loss and influences on religious orientation. The influence of cultural beliefs and background on Chinese parents as they deal with the issue of a child's death was apparent. Further research is needed and will benefit our understanding of parental bereavement in Chinese families.     

From C. P. Ellis to School Integration: The Social Psychology of Conflict Reduction

In this article, the authors review social psychological theories of intergroup conflict reduction. Emphasis is placed on three interrelated social conditions which facilitate conflict reduction: intergroup contact, superordinate goals, and shared identities. Bridging experimental research with real‐world studies of schooling, these concepts are applied to understanding the process of school integration. Social contexts which present conflicting parties with a new shared goal and identity, as well as opportunities to become familiar with others beyond stereotypes and anxious reactions, dramatically increase the likelihood of diffusing conflict.
