Migrating Faculty Publications from a Department Website to an Institutional Repository

In October 2013, George Washington University\u27s School of Public Health and Health Services (now the Milken Institute School of Public Health) approached the Himmelfarb Health Sciences Library about moving a large collection of Health Policy Department publications and citations from the school\u27s website into the Health Sciences Research Commons (HSRC) institutional repository. After a project planning meeting with the school\u27s representative, library staff began uploading documents and citations from the collection. Working from a spreadsheet and file set provided by the school, library staff processed 604 citations (including 319 full-text files) dating back to 1996. Despite some problem files and citations, the majority were added to HSRC between November 2013 and April 2014. The successful completion of this project led to increased exposure of faculty research through standardized metadata, search engine optimization, and inclusion of research in the Digital Commons Network. Additionally, the establishment of new partnerships between the library and the public health school opened the door to future scholarly communications collaborations

Who Are the Homeless? Numbers, Trends and Characteristics of Those Without Homes in Calgary

In 2008, Calgary was the first city in Canada to institute a 10-year plan to end homelessness. The plan was introduced in part due to the steady and rapid growth in homelessness in the city since 1992. Since 2008 growth in the number of homeless people has stopped despite a rapidly growing city. The number of people enumerated as homeless by point-in-time counts has fallen from 304 persons per 100,000 population to 256 persons per 100,000 population in 2014, a drop of more than 15 per cent. Looking beyond simple counts of the number of homeless people, we examine how people who are homeless use emergency shelters. Tracking shelter use over a five year period by nearly 33,000 individuals, we find that, contrary to what might be thought to be true, the great majority (86%) of people who use emergency shelters in Calgary do so very infrequently and for only short periods of time. Visiting shelters less than twice (on average), these “transitional” users stayed in shelters for an average of only 15 days spread during the five years of our study. Another 12% of people used emergency shelters more frequently; an average of 8 times spread over five years. These “episodic” users stayed for a total of 113 days on average. Only a tiny minority, just 1.6% of all shelter users, stayed in shelters for very long periods. These “chronic” users visited shelters an average of three and a half times and stayed a total of 928 days over the five years of our study. Because they stay in shelters for long periods, chronic shelter users occupy one-third of shelter beds. The implication of this is that finding stable, supportive housing for just 1.6% of those experiencing homeless – a total of about 900 individuals in Calgary -- would free-up one-third of beds in emergency shelters. Providing supportive housing for episodic users as well would free-up another one-third of beds and so enable shelter providers to focus on their main function as providers of emergency housing. Moving people from emergency shelters into supportive housing delivers savings in the form of reduced interactions for these people with the criminal justice and healthcare systems; savings that have been shown in other studies to significantly off-set the cost of supportive housing. Planning to end homelessness has always been an ambitious goal. While the homeless serving community has made significant gains in understanding how best to solve the problem, greater effort may be required of local, provincial and federal policy makers to find ways of resolving the issue that is at the heart of Calgary’s homelessness problem; namely, the lack of affordable rental accommodations

Amine- and Sulfide-sensing Copper(I) Iodide Films

Copper(I) iodide films were cast onto glass from solution. The CuI films absorb vapor-phase amine and sulfide molecules, producing a range of photoluminescent emission colors. Spectroscopic data suggest the presence of low energy CuI cluster-centered transitions

Does this Feel Empowering? Using Métissage to Explore the Effects of Critical Pedagogy

The extent to which critical pedagogy disrupts the relations of dominance inside postsecondary classrooms, or empowers students to take socially just action beyond the classroom has been debated and challenged for decades. Through the use of métissage, an interpretive inquiry method that affords collaborative interrogation of individual narrative writings, we five participants in the same critical pedagogy course conducted a post-course inquiry project in order to explore what we had learned through the course. Through this inquiry project, we have come to a deeper understanding of critical pedagogy praxis. Ultimately, what we learned through the use of this inquiry method maintains important implications for postsecondary educators

The role of endogenous opioid neuropeptides in neurostimulation-driven analgesia

Due to the prevalence of chronic pain worldwide, there is an urgent need to improve pain management strategies. While opioid drugs have long been used to treat chronic pain, their use is severely limited by adverse effects and abuse liability. Neurostimulation techniques have emerged as a promising option for chronic pain that is refractory to other treatments. While different neurostimulation strategies have been applied to many neural structures implicated in pain processing, there is variability in efficacy between patients, underscoring the need to optimize neurostimulation techniques for use in pain management. This optimization requires a deeper understanding of the mechanisms underlying neurostimulation-induced pain relief. Here, we discuss the most commonly used neurostimulation techniques for treating chronic pain. We present evidence that neurostimulation-induced analgesia is in part driven by the release of endogenous opioids and that this endogenous opioid release is a common endpoint between different methods of neurostimulation. Finally, we introduce technological and clinical innovations that are being explored to optimize neurostimulation techniques for the treatment of pain, including multidisciplinary efforts between neuroscience research and clinical treatment that may refine the efficacy of neurostimulation based on its underlying mechanisms

The performance of model-based indices given alternative sampling strategies in a climate-adaptive survey design

Species-distribution shifts are becoming commonplace due to climate-driven change. Difficult decisions to modify survey extent and frequency are often made due to this change and constraining survey budgets. This often leads to spatially and temporally unbalanced survey coverage. Spatio-temporal models are increasingly used to account for spatially unbalanced sampling data when estimating abundance indices used for stock assessment, but their performance in these contexts has received little research attention. We therefore seek to answer two questions: (1) how well can a spatio-temporal model estimate the proportion of abundance in a new “climate-adaptive” spatial stratum? and (2) when sampling must be reduced, does annual sampling at reduced density or biennial sampling result in better model-based abundance indices? We develop a spatially varying coefficient model in the R package VAST using the eastern Bering Sea (EBS) bottom trawl survey and its northern Bering Sea (NBS) extension to address these questions. We first reduce the spatial extent of survey data for 30 out of 38 years of a real survey in the EBS and fit a spatio-temporal model to four commercially important species using these “data-reduction” scenarios. This shows that a spatio-temporal model generally produces similar trends and density estimates over time when large portions of the sampling domain are not sampled. However, when the central distribution of a population is not sampled the estimates are inaccurate and have higher uncertainty. We also conducted a simulation experiment conditioned upon estimates for walleye pollock (Gadus chalcogrammus) in the EBS and NBS. Many species in this region are experiencing distributional shifts attributable to climate change with species historically centered in the southeastern portion of the survey being increasingly encountered in the NBS. The NBS was occasionally surveyed in the past, but has been surveyed more regularly in recent years to document distributional shifts. Expanding the survey to the NBS is costly and given limited resources the utility of reducing survey frequency versus reducing sampling density to increase survey spatial extent is under debate. To address this question, we simulate survey data from alternative sampling designs that involve (1) annual full sampling, (2) reduced sampling in the NBS every year, or (3) biennial and full sampling in the NBS. Our results show that annual sampling, even with reduced sampling density, provides less biased abundance information than biennial sampling. We therefore conclude that ideally fishery-independent surveys should be conducted annually and spatio-temporal models can help to provide reliable estimates

Thinking and acting both globally and locally : The Field School in intercultural education as a model for action-research training and civic learning.

We present the Field School model of intercultural civic education, service-learning, action research training, and collaboration (with local academic and community partners) based on field work in applied anthropology. Theoretical and methodological foundations of the Field School also include experiential learning and immersive pedagogy, multiculturalism and cross-cultural communication, international education and study abroad programs, collaborative international development, participatory research, and in-depth knowledge in one’s own specific discipline. The primary goals of these intensive, short-term action research projects in other, less-developed countries or regions are benefits for community partners that are as sustainable as possible and to foster and assess learning experiences of students. The Peabody-Vanderbilt Field School in Intercultural Education began in Ecuador and Argentina, but we focus on Field Schools in China, rural New Mexico, and South Africa. In Guangxi, P.R.C., U.S. and Chinese students learned to navigate political and cultural complexities to study migration, community needs and assets assessment, and health effects of changing diet on children, and assisted English language learning in schools, a university and a factory. Native American students from Gallup, NM, and students from Nashville, TN, travelled to each other’s locale to study the impact of diabetes in each culture and develop health education and other prevention strategies. In Cape Town, SA, students worked on health and education projects in three townships; we focus here on a collaboration with high school staff to study and reduce the high dropout rate. We analyze Field School impacts on local community partners and student-researchers

Additive drug-specific and sex-specific risks associated with co-use of marijuana and tobacco during pregnancy: Evidence from 3 recent developmental cohorts (2003-2015).

BACKGROUND: Methodologic challenges related to the concomitant use (co-use) of substances and changes in policy and potency of marijuana contribute to ongoing uncertainty about risks to fetal neurodevelopment associated with prenatal marijuana use. In this study, we examined two biomarkers of fetal neurodevelopmental risk-birth weight and length of gestation-associated with prenatal marijuana use, independent of tobacco (TOB), alcohol (ALC), other drug use (OTH), and socioeconomic risk (SES), in a pooled sample (N = 1191) derived from 3 recent developmental cohorts (2003-2015) with state-of-the-art substance use measures. We examined differential associations by infant sex, and multiplicative effects associated with co-use of MJ and TOB. METHODS: Participants were mother-infant dyads with complete data on all study variables derived from Growing Up Healthy (n = 251), Behavior and Mood in Babies and Mothers (Cohorts 1 and 2; n = 315), and the Early Growth and Development Study (N = 625). We estimated direct effects on birth weight and length of gestation associated with MJ, TOB, and co-use (MJ x TOB), using linear regression analysis in the full sample, and in male (n = 654) and female (n = 537) infants, separately. RESULTS: Mean birth weight and length of gestation were 3277 g (SD = 543) and 37.8 weeks (SD = 2.0), respectively. Rates of prenatal use were as follows: any use, n = 748 (62.8%); MJ use, n = 273 (22.9%); TOB use, n = 608 (51.0%); co-use of MJ and TOB, n = 230 (19.3%); ALC use, n = 464 (39.0%); and OTH use n = 115 (9.7%.) For all infants, unique effects on birth weight were observed for any MJ use [B(SE) = -84.367(38.271), 95% C.I. -159.453 to -9.281, p = .028], any TOB use [B(SE) = -0.99.416(34.418), 95% C.I. -166.942 to -31.889, p = .004], and each cigarette/day in mean TOB use [B(SE) = -12.233(3.427), 95% C.I. -18.995 to -5.510, p \u3c .001]. Additional effects of co-use on birth weight, beyond these drug-specific effects, were not supported. In analyses stratified by sex, while TOB use was associated with lower birth weight in both sexes, MJ use during pregnancy was associated with lower birth weight of male infants [B(SE) = -153.1 (54.20); 95% C.I. -259.5 to -46.7, p = .005], but not female infants [B(SE) = 8.3(53.1), 95% C.I. -96.024 to 112.551, p = .876]. TOB, MJ, and their co-use were not associated with length of gestation. CONCLUSIONS: In this sample, intrauterine co-exposure to MJ and TOB was associated with an estimated 18% reduction in birth weight not attributable to earlier delivery, exposure to ALC or OTH drugs, nor to maternal SES. We found evidence for greater susceptibility of male fetuses to any prenatal MJ exposure. Examination of dose-dependence in relationships found in this study, using continuous measures of exposure, is an important next step. Finally, we underscore the need to consider (a) the potential moderating influence of fetal sex on exposure-related neurodevelopmental risks; and (b) the importance of quantifying expressions of risk through subtle alterations, rather than dichotomous outcomes
