Impact of a Diversity Conference on University Curriculum, Recruitment, and Accreditation Efforts

Diversity of students, faculty, administrative staff, community, and curriculum is an asset thought to strengthen and enrich students’ academic experiences. Responding to a charge from a Northern Michigan University president to place diversity at the center of a University Strategic Plan, members of a diversity advisory council proposed a plan to prepare the university and its students for a future in an increasingly diverse and globalized society. Integral to this plan was a diversity conference, UNITED (Uniting Neighbors in the Experience of Diversity), which went from an annual September event to an integral part of the university\u27s academic fabric. Our research describes an eight-year history of the diversity conference, which has hosted more than 12,000 participants and has become a vital component in the curriculum of the university. The research assists in outcomes assessment efforts to determine whether the diversity conference has lived up to its original purpose and perceived importance in the curriculum, recruitment of students, and program accreditation efforts

Successive Study of Diversity Conference Evaluations of Presenters by Race, Gender, Sexual Orientation, and Disability

A Midwestern university’s annual diversity conference hosts about 1,500 attendees from a campus of 9,000 students. Using a successive independent samples design, a series of cross-sectional surveys were conducted to answer the research question, how does a presenter’s race, gender, and ability/disability affect participant responses on conference evaluations. A review of the literature has determined that our research represents the largest and longest empirical study of a higher education diversity conference in the United States. The research is a comparative study of evaluation trends of conference attendees toward diversity conference presenters based on race, gender, and disability over eight years from 2006 to 2013. Ten evaluation items provided qualitative and quantitative data on topics of quality, likes best, shortcomings, meets expectations, and level of appropriateness. Over 4000 evaluations were analyzed over an 8-year period, resulting in a 33% evaluation response rate. Content analysis of evaluation data revealed underlying themes in attendees’ general comments. Threats to validity are discussed. Statistical analyzes include descriptive statistics, Chi-square, and regression analyses of contrasting trends in conference attendees’ evaluations. A trends analysis of diversity conference evaluations articulates the reality that in modern societies, humans may occupy a number of social groups in the same social/political public space, but the perceived diversity of individuals and social groups result in differences in evaluations of quality and performance

Effecting Land-Use Changes Through Education and Implementation: Assessing the Effectiveness of the Watershed Stewards Program

Over the past 7 years, the University of Maine Cooperative Extension (UMCE) has conducted the Watershed Stewards Program (WSP), a 20-hour lake education and implementation program. To assess program effectiveness, we studied whether our program significantly improved program participant knowledge level over non-participants through quantitative and qualitative measures. An objective, 15-question test was administered to program participants and other people living in these lake watersheds. Stewards scored significantly (23%) higher on the objective test than those who had not been involved in the program. Program participants qualitatively demonstrated much more involvement with lake governance, implementation efforts, and related activities

Sex differences in binge-like EtOH drinking, corticotropin-releasing hormone and corticosterone: effects of β-endorphin

Binge drinking is an increasingly common pattern of risky use associated with numerous health problems, including alcohol use disorders. Because low basal plasma levels of βendorphin (β-E) and an increased β-E response to alcohol are evident in genetically at-risk human populations, this peptide is thought to contribute to the susceptibility for disordered drinking. Animal models suggest that the effect of β-E on consumption may be sex-dependent. Here, we studied binge-like EtOH consumption in transgenic mice possessing varying levels of β-E: wild-type controls with 100% of the peptide (β-E +/+), heterozygous mice constitutively modified to possess 50% of wild-type levels (β-E +/−) and mice entirely lacking the capacity to synthesize β-E (−/−). These three genotypes and both sexes were evaluated in a 4-day, two-bottle choice, drinking in the dark paradigm with limited access to 20% EtOH. β-E deficiency determined sexually divergent patterns of drinking in that β-E −/− female mice drank more than their wild-type counterparts, an effect not observed in male mice. β-E −/− female mice also displayed elevated basal anxiety, plasma corticosterone and corticotropin-releasing hormone mRNA in the extended amygdala, and all of these were normalized by EtOH self-administration. These data suggest that a heightened risk for excessive EtOH consumption in female mice is related to the drug\u27s ability to ameliorate an overactive anxiety/stress-like state. Taken together, our study highlights a critical impact of sex on neuropeptide regulation of EtOH consumption

Receptor modeling application framework for particle source apportionment

Receptor models infer contributions from particulate matter (PM) source types using multivariate measurements of particle chemical and physical properties. Receptor models complement source models that estimate concentrations from emissions inventories and transport meteorology. Enrichment factor, chemical mass balance, multiple linear regression, eigenvector, edge detection, neural network, aerosol evolution, and aerosol equilibrium models have all been used to solve particulate air quality problems, and more than 500 citations of their theory and application document these uses. While elements, ions, and carbons were often used to apportion TSP, PM10, and PM2.5 among many source types, many of these components have been reduced in source emissions such that more complex measurements of carbon fractions, specific organic compounds, single particle characteristics, and isotopic abundances now need to be measured in source and receptor samples. Compliance monitoring networks are not usually designed to obtain data for the observables, locations, and time periods that allow receptor models to be applied. Measurements from existing networks can be used to form conceptual models that allow the needed monitoring network to be optimized. The framework for using receptor models to solve air quality problems consists of: (1) formulating a conceptual model; (2) identifying potential sources; (3) characterizing source emissions; (4) obtaining and analyzing ambient PM samples for major components and source markers; (5) confirming source types with multivariate receptor models; (6) quantifying source contributions with the chemical mass balance; (7) estimating profile changes and the limiting precursor gases for secondary aerosols; and (8) reconciling receptor modeling results with source models, emissions inventories, and receptor data analyses

Systematic review and meta-analysis of risk of gestational diabetes in women with preconception mental disorders

There is a well-established bidirectional association between Type 2 diabetes and mental disorder and emerging evidence for an increased risk of perinatal mental disorder in women with gestational diabetes (GDM). However, the relation between mental disorder prior to pregnancy and subsequent risk of GDM remains relatively unexplored. This is a systematic review and meta-analysis of the risk of GDM in women with a range of preconception mental disorders. Peer-reviewed literature measuring odds of GDM and preconception mood, anxiety, psychotic and eating disorders was systematically reviewed. Risk of bias was assessed using a checklist. Two independent reviewers were involved. 22 observational studies met inclusion criteria; most were retrospective cohorts from English speaking, high income countries. 14 studies were at high risk of bias. There was evidence for an increased risk of GDM in women with schizophrenia (pooled OR 2.44; 95% CI 1.17,5.1; 5 studies) and a reduced risk of GDM in women with anorexia nervosa (pooled OR 0.63; 95% CI 0.49,0.80; 5 studies). There was some limited evidence of an increased risk in women with bipolar disorder. There was no evidence for an association with preconception depression or bulimia nervosa on meta-analysis. There were insufficient studies on anxiety disorders for meta-analysis. This review indicates that there is not a significant risk of GDM associated with many preconception mental disorders but women with psychotic disorders represent a group uniquely vulnerable to GDM. Early detection and management of GDM could improve physical and mental health outcomes for these women and their children

Sex and β-Endorphin Influence the Effects of Ethanol on Limbic Gabra2 Expression in a Mouse Binge Drinking Model

Binge drinking is a widespread problem linked to increased risk for alcohol-related complications, including development of alcohol use disorders. In the last decade, binge drinking has increased significantly, specifically in women. Clinically, sexually dimorphic effects of alcohol are well-characterized, however, the underlying mechanisms for these dimorphisms in the physiological and behavioral effects of alcohol are poorly understood. Among its many effects, alcohol consumption reduces anxiety via the inhibitory neurotransmitter GABA, most likely acting upon receptors containing the α-2 subunit (Gabra2). Previous research from our laboratory indicates that female mice lacking the endogenous opioid peptide β-endorphin (βE) have an overactive stress axis and enhanced anxiety-like phenotype, coupled with increased binge-like alcohol consumption. Because βE works via GABA signaling to reduce anxiety, we sought to determine whether sexually dimorphic binge drinking behavior in βE deficient mice is coupled with differences in CNS Gabra2 expression. To test this hypothesis, we used βE knock-out mice in a drinking in the dark model where adult male and female C57BL/6J controls (βE +/+) and βE deficient (βE -/-; B6.129S2-Pomctm1Low/J) mice were provided with one bottle of 20% ethanol (EtOH) and one of water (EtOH drinkers) or two bottles of water (water drinkers) 3 h into the dark cycle for four consecutive days. Following a binge test on day 4, limbic tissue was collected and frozen for subsequent qRT-PCR analysis of Gabra2 mRNA expression. Water-drinking βE +/+ females expressed more Gabra2 in central nucleus of the amygdala and the bed nucleus of the stria terminalis than males, but this sex difference was absent in the βE -/- mice. Genotype alone had no effect on alcohol consumption or drug-induced increase in Gabra2 expression. In contrast, βE expression had bi-directional effects in females: in wildtypes, Gabra2 mRNA was reduced by binge EtOH consumption, while EtOH increased expression in βE -/- females to levels commensurate with drug-naïve βE +/+ females. These results support the contention that βE plays a role in sexually dimorphic binge-like EtOH consumption, perhaps through differential expression of GABAA α2 subunits in limbic structures known to play key roles in the regulation of stress and anxiety

An Assessment of Oral Health on the Pine Ridge Indian Reservation

An assessment on the oral health of 292 Oglala Lakota residents of the Pine Ridge Indian Reservation in South Dakota looks at dental issues, periodontal disease, oral lesions and need for dental care. The research was conducted by the University of Colorado, Center for Native Oral Health Research and funded by the W.K. Kellogg Foundation
