Black widow spiders in an urban desert: Population variation in an arthropod pest across metropolitan Phoenix, AZ

The effects of urban disturbance are critical to understand, as the majority of the world??s population now resides in urban centers. For example, urbanization often leads to reduced species diversity at the expense of a few urban-adapted taxa. However, it remains unclear why some taxa thrive following human disturbance whereas others do poorly. The western black widow spider, Latrodectus hesperus, thrives in disturbed, urban habitat??often forming dense aggregations (i.e., infestations) relative to typical low-density, desert populations. We examined the population dynamics of ten black widow aggregations spread across metropolitan Phoenix, AZ, during the peak of the breeding season (June?CAugust). Here we show that prey abundance, female mass, web volume and population density exhibit minimal temporal variation across the breeding season, but that prey abundance, female mass and population density show significant spatial variation across the ten urban aggregations. Our measure of prey abundance and foraging success, the number of prey carcasses found in black widow webs, shared a strong positive relationship with female mass and population density, but not with web volume. Surprisingly, female mass, web volume and population density were not correlated with each other. The abiotic variables we measured at each site did a poor job of explaining black widow population parameters, although we did find a marginal trend for more recent developments to harbor denser black widow aggregations. Our findings support the generalization that urbanization heightens spatial variation, and we suggest that local urban prey abundance is influential in promoting urban infestations full of heavy, fecund female black widows. Studies of the population ecology of urban pests are necessary to identify the mechanisms allowing some species to thrive following human disturbance while much native biodiversity is lost following urbanization.     

Body Appreciation and Contraceptive Use Among College Women: A Brief Report

Research suggests that body image and sexual behaviors are related, with poor body image associated with risky behaviors and positive body image related to protective behaviors. However, few studies explore the relationships between positive body image and contraceptive use. Accordingly, the current study investigated the relationship between body appreciation and barrier and hormonal contraceptive use among college women (N = 399). Body appreciation was significantly related to male condom use and to the use of both male condoms and a hormonal contraceptive. These findings are promising as dual contraceptive use is the best way to prevent unintended pregnancy and sexually transmitted infections (STIs).     

Rural Environmental Concern: Effects of Position,Partisanship, and Place

The social bases of environmental concern in rural America resemble those for the nation as a whole, but also reflect the influence of place. Some general place characteristics, such as rates of population growth or resource‐industry employment, predict responses across a number of environmental issues. Other unique or distinctive aspects of local society and environment matter as well. We extend earlier work on both kinds of place effects, first by analyzing survey data from northeast Oregon. Results emphasize that “environmental concern” has several dimensions. Second, we contextualize the Oregon results using surveys from other regions. Analysis of an integrated dataset (up to 12,000 interviews in 38 U.S. counties) shows effects from respondent characteristics and political views, and from county rates of population growth and resource‐based employment. There also are significant place‐to‐place variations that are not explained by variables in the models. To understand some of these we return to the local scale. In northeast Oregon, residents describe how perceptions of fire danger from unmanaged forest lands shape their response to the word conservation. Their local interpretation contrasts with more general and urban connotations of this term, underlining the importance of place for understanding rural environmental concern.     

Methodological triangulation in researching families: Making sense of dissonant data

The research literature on triangulation has paid little attention to the problematic of 'making sense of dissonant data'. Nor has there been much discussion around the use of the technique of triangulation when researching families. Through a presentation of research findings gathered from self-report questionnaires and in-depth interviews with couples and families the possibilities of convergent, complementary and dissonant data and their interpretation are explored. The paper reflects on the ontological, epistemological and methodological tensions that must be negotiated when working with triangulated data. It is argued that given the multi-faceted context and intimate subject matter in family and couples research there is a high likelihood of dissonant findings. Recommendations are made for family researchers interested in the technique of triangulation to consider the context and process of their research in the interpretation of their data. Despite the challenges that triangulation throws up for researchers, it is argued that working within a post-positivist paradigm, triangulation enables analysis which is both more complex and more meaningful.     

The Utility of a Gender-Specific Definition of Binge Drinking on the AUDIT

Abstract

Objective: Although binge drinking is commonly defined as the consumption of at least 5 drinks in 1 sitting for men and 4 for women, the Alcohol Use Disorders Identification Test (AUDIT) defines binge drinking as the consumption of 6 or more drinks in 1 sitting for both men and women. This study examined the effect of using gender-specific binge drinking definitions on overall AUDIT scores. Participants: Participants were 331 college men and 1224 college women. Methods: Participants completed a self-report questionnaire, which included the AUDIT. Results: Findings showed that defining binge drinking as 4 or more drinks for women, rather than 6 or more, does impact their AUDIT scores and could affect the percentage of women classified as hazardous users. Among men, AUDIT scores were unaffected by the use of a gender-specific definition of binge drinking. Conclusions: Results suggest that the AUDIT might be underidentifying hazardous users among college women.     

Psychotropic Drug Use Among College Students: Patterns of Use,Misuse, and Medical Monitoring

Abstract

Objective: To assess whether college students who use psychotropic drugs are (1) aware of potential side effects, (2) appropriately monitored by prescribing physicians, and (3) taking medications as prescribed. Participants: Fifty-five college students, currently taking psychotropic medications, were recruited between Summer 2008 and Fall 2009. Methods: Participants were given interviews assessing (1) interactions with prescribing physicians, (2) patterns of psychotropic drug use, and (3) Diagnostic and Statistical Manual of Mental Disorders Fourth Edition (DSM-IV) substance use disorders. Results: Twenty-five percent of participants did not remember being assessed for suicidal ideation. A large number of participants took their medications in different quantities or frequencies than prescribed and 35% of participants met DSM criteria for substance dependence. Conclusions: Many students are misusing psychotropic medications and this misuse is not being communicated with prescribing physicians.     

An examination of gender difference in advancement and salary for Marriage and Family Therapy faculty members working in public universities

Evidence for inequitable advancement and salary disparity for women in academia is compelling, but only a marginal amount of research has explored this in the field of Marriage and Family Therapy (MFT) specifically. Current research provides preliminary evidence that women remain underrepresented at the Full Professor rank and are paid less than men MFT faculty. This study collected publicly available data for MFT faculty in public universities to explore gender differences in advancement between ranks, salary disparity, and the representation of women and men in the highest and lowest paying niches of MFT academia. Results showed that, despite being 60.15% of MFTs in public universities, women were paid an average of $5596.25 less than men. Men were 1.40 times more likely than women to be promoted to Full Professor on time—within 13 years of their terminal degree. Implications for addressing inequitable advancement and salary disparity for women MFT faculty are discussed.     

Contextualizing Mexican Migrant Education Selectivity

The debate on whether Mexican immigrants are positively or negatively selected on education has been limited by studying immigrants in data collected only from the sending or the destination country. Using nationally representative data from Mexico that tracked migrants to the United States prospectively, we examine the education selectivity of Mexicans who immigrated to the United States from 2002 to 2005. We find that using reports of migration by remaining household members and proxy substitution of migration education underestimates migrant selectivity. Migrant men and women were positively selected within households and rural municipalities of origin but negatively selected from the national educational distribution. Differences in selectivity by size of place, as well as when considering the local or national context, means that the answer of whether immigrants are positively or negatively selected on education depends on the context considered.     

Devolution and Patient Choice: Policy Rhetoric versus Experience in Practice

Background: market reforms in England have been identified as making a clear distinction between English health policy and health policy in the devolved systems in Northern Ireland, Scotland and Wales. Patient choice is a high profile policy in the English National Health Service that constitutes significant changes to the demand side of health care. It is not clear what national differences this has led to regarding implementation of policy. This article presents the findings from a large UK‐wide study on the development and implementation of policies related to patient choice of provider. The findings reported here relate specifically to the policy development and organizational implementation of choice in order to examine the impact of devolution on health care policy. Aim: this study examines patient choice of provider across all four countries of the UK to understand the effect of differences in national policies on the organization and service how choice of provider presented to patients. Methods: at the macro‐level, we interviewed policymakers and examined policy and guidance documents to analyze the provenance and determinants of national policy in each UK nation. At the Primary Care Trust or Health Board level, we interviewed a range of public and private health service providers to identify the range of referral pathways and where and when choices might be made. Finally, we interviewed ear, nose and throat, and orthopaedics patients to understand how such choices were experienced. Findings: while we found that distinct rhetorical differences were identifiable at a national policy level, these were less visible at the level of service organization and the way choices were provided to patients. Conclusion: historical similarities in both the structure and operation of health care, coupled with common operational objectives around efficient resource use and waiting times, mediate how strategic policy is implemented and experienced in the devolved nations of the UK.
