Under the Bridge: A Qualitative Investigation of Homeless Persons\u27 Perspectives on Substance Abuse and Its Treatment

Although homelessness is generally thought of as an urban problem, it is also a growing problem in rural areas, such as Missoula, Montana (Jacobson 2010). Studies of urban homelessness indicate that substance abuse is a part of life for many homeless individuals, and the barriers to substance abuse treatment are exacerbated by being homeless (Snow and Anderson 1993; Morrell 2007). “Prevalence studies estimate that the percentage of homeless people with alcohol use disorders to be at 30%-40% and drug abuse at 10%-15%” (Fisk, Raakfeldt, and McCormack 2006: 480). Substance abuse is also common among homeless individuals in rural areas, including Missoula, where this research takes place (Jacobson 2010). This research takes place in the only ‘wet’ day center for homeless persons in Missoula. Unlike traditional homeless shelters, harm reduction facilities or ‘wet’ facilities provide services to those under the influence of drugs and/or alcohol. Clients of ‘wet’ facilities offer an important perspective on substance abuse and treatment, as they are most likely to have experiences with both. To better understand this population, this project uses participant observation and in-depth interviews with clients and staff of a ‘wet’ facility to explain their perceived and experienced barriers to substance abuse treatment

Anisotropic small-scale constraints on energy in rotating stratified turbulence

Author's version issued as working paper on Arxiv.orgRapidly rotating, stably stratified three-dimensional inviscid flows conserve both energy and potential enstrophy. We show that in such flows, the forward cascade of potential enstrophy imposes anisotropic constraints on the wavenumber distribution of kinetic and potential energy. The horizontal kinetic energy is suppressed in the large, nearly horizontal wave modes, and should decay with the horizontal wavenumber as $k_h^{-3}$. The potential energy is suppressed in the large, nearly vertical wave modes, and should decay with the vertical wavenumber as $k_z^{-3}$. These results augment the only other exact prediction for the scaling of energy spectra due to constraints by potential enstrophy obtained by Charney (J. Atmos. Sci. 28, 1087 (1971)), who showed that in the quasi-geostrophic approximation for rotating stratified flows, the energy spectra must scale isotropically with total wavenumber as $k^{-3}$. We test our predicted scaling estimates using resolved numerical simulations of the Boussinesq equations in the relevant parameter regimes, and find reasonable agreement

Several new quadrature formulas for polynomial integration in the triangle

Working paper submitted to arxiv.org by authorsWe present several new quadrature formulas in the triangle for exact integration of polynomials. The points were computed numerically with a cardinal function algorithm which imposes that the number of quadrature points $N$ be equal to the dimension of a lower dimensional polynomial space. Quadrature forumulas are presented for up to degree $d=25$, all which have positive weights and contain no points outside the triangle. Seven of these quadrature formulas improve on previously known results

Clery Act Needs Whistleblower Protection

In light of the apparent cover-up by the leadership at Eastern Michigan University (EMU) of a student rape and murder on campus, Congress should amend the Jeanne Clery Act. Specifically, a whistleblower protection section needs to be added to this landmark sunshine law

Say it in Polish! : The Role of Heritage Language in preserving culture among families of Eastern European Origin

This project is part of a larger qualitative research study exploring the relationship between Eastern European American parenting styles and children\u27s academic achievement. Seven mothers who were either first- or second-generation Eastern European American participated in semi-structured individual interviews. This project focuses on heritage language preservation. It revealed motivations, strategies, and outcomes of parents\u27 desire to transmit their heritage language to the next generation. All participants had at least one child between ages five and eighteen. Based on our findings, four themes have emerged: 1) Motivations for heritage language preservation; 2) Resources and strategies to foster heritage language learning; 3) Family factors affecting heritage language transmission and fluency; and 4) Children\u27s evolving attitudes to heritage language.https://engagedscholarship.csuohio.edu/u_poster_2016/1001/thumbnail.jp

Lock & Load? The 2nd Amendment Arrives on Campus

Thanks to the U.S. Supreme Court’s watershed decision regarding the Second Amendment in June, state lawmakers, university policymakers and campus safety personnel nationwide face a conundrum that must be answered in a prudent way. The solution will greatly impact the daily lives of everyone on campus

Sexual selection and predation drive the repeated evolution of stridulation in Heteroptera and other arthropods

Acoustic and substrate-borne vibrations are among the most widely used signalling modalities in animals. Arthropods display a staggering diversity of vibroacoustic organs generating acoustic sound and/or substrate-borne vibrations, and are fundamental to our broader understanding of the evolution of animal signalling. The primary mechanism that arthropods use to generate vibroacoustic signals is stridulation, which involves the rubbing together of opposing body parts. Although stridulation is common, its behavioural context and evolutionary drivers are often hard to pinpoint, owing to limited synthesis of empirical observations on stridulatory species. This is exacerbated by the diversity of mechanisms involved and the sparsity of their description in the literature, which renders their documentation a challenging task. Here, we present the most comprehensive review to date on the systematic distribution and behavioural context of stridulation. We use the megadiverse heteropteran insects as a model, together with multiple arthropod outgroups (arachnids, myriapods, and selected pancrustaceans). We find that stridulatory vibroacoustic signalling has evolved independently at least 84 times and is present in roughly 20% of Heteroptera, representing a remarkable case of convergent evolution. By studying the behavioural context of stridulation across Heteroptera and 189 outgroup lineages, we find that predation pressure and sexual selection are the main behaviours associated with stridulation across arthropods, adding further evidence for their role as drivers of large-scale signalling and morphological innovation in animals. Remarkably, the absence of tympanal ears in most Heteroptera suggests that they typically cannot detect the acoustic component of their stridulatory signals. This demonstrates that the adoption of new signalling modalities is not always correlated with the ability to perceive those signals, especially when these signals are directed towards interspecific receivers in defensive contexts. Furthermore, by mapping their morphology and systematic distribution, we show that stridulatory organs tend to evolve in specific body parts, likely originating from cleaning motions and pre-copulatory displays that are common to most arthropods. By synthesising our understanding of stridulation and stridulatory organs across major arthropod groups, we create the necessary framework for future studies to explore their systematic and behavioural significance, their potential role in sensory evolution and innovation, and the biomechanics of this mode of signalling
