    This paper looks at the variables that determine the location of hydraulic fracturing wells. Using cross-sectional data on Texas counties, we test whether county income level and the percentage of the population that is minority are significant indicators of well location. This study mirrors other studies that focus on the location of undesirable land uses such as landfills. Our study finds that income level and the size of the minority population are not statistically significant indicators of hydraulic fracturing well location

    Freshwater Pearl Mussel (Margaritifera Margaritifera) Host Choice and Behavioural Responses to Changes in Flow Regime

    The endangered freshwater pearl mussel (Margaritifera margaritifera), one of the longest-lived invertebrates, are threatened globally. Scotland, UK, remains a stronghold, however even here the population is declining due to factors such as habitat degradation, pollution and pearl fishing. The study comprised two parts: field surveys of glochidia infection of host salmonid fish, and a novel laboratory flume based study of the mussel‟s behavioral responses to changes in flow regime. The intricate life cycle of M.margaritifera includes a parasitic stage as glochidia attached to gills of salmonids. The preferred host in Scotland is thought to be Salmo salar and Salmo trutta in the absence of S.salar. This has not, however, been empirically tested in the field. Eight rivers in NW Scotland were surveyed using standard electrofishing techniques and encysted glochidia counted. Results suggest S.trutta is the primary host fish for glochidia attachment in the rivers surveyed, which contradicts current accepted knowledge about host specificity of M.margaritifera. Mussel populations are often found in regulated rivers, however little data exists on response to changes in flow regime. The mussel's behavioral response to changes in flow were investigated in an experimental flume. Mussels buried significantly deeper in conditions of gradually increasing water velocity compared with rapid increases or where water velocity was constant. 68% of individual mussels washed out when the water velocity was rapidly increased. The findings are novel, provide initial recommendations for targeted management actions for the conservation of M.margaritifera both in Scotland and internationally, and highlight more research is required

    Deep neutral hydrogen observations of Leo T with the Westerbork Synthesis Radio Telescope

    Leo T is the lowest mass gas-rich galaxy currently known and studies of its gas content help us understand how such marginal galaxies survive and form stars. We present deep neutral hydrogen (HI) observations from the Westerbork Synthesis Radio Telescope in order to understand its HI distribution and potential for star formation. We find a larger HI line flux than the previously accepted value, resulting in a 50% larger HI mass of 4.1 x 10^5 Msun. The additional HI flux is from low surface brightness emission that was previously missed; with careful masking this emission can be recovered even in shallower data. We perform a Gaussian spectral decomposition to find a cool neutral medium component (CNM) with a mass of 3.7 x 10^4 Msun, or almost 10% of the total HI mass. Leo T has no HI emission extending from the main HI body, but there is evidence of interaction with the Milky Way circumgalactic medium in both a potential truncation of the HI body and the offset of the peak HI distribution from the optical center. The CNM component of Leo T is large when compared to other dwarf galaxies, even though Leo T is not currently forming stars and has a lower star formation efficiency than other gas-rich dwarf galaxies. However, the HI column density associated with the CNM component in Leo T is low. One possible explanation is the large CNM component is not related to star formation potential but rather a recent, transient phenomenon related to the interaction of Leo T with the Milky Way circumgalactic medium.Comment: accepted for publication in A&A; 12 pages, 13 figure

    Writing a Narrative CV

    This workbook guides you through reflective questions to help you with a narrative CV. What you write here will probably be much longer than the word or space limit that you will ultimately have in a grant or Fellowship application. It’s important that you read the call guidance each time.Think of this as your ‘master’ narrative CV document. When it comes to writing the one for the actual application, you will be pulling out the key bits of information which support you to demonstrate that you are the right person (or part of the right team), with a unique set of experiences, to be able to deliver the grant you are applying to. The examples here are written from an ECR or PGR perspective but every answer will be unique

    Implementation of the Nurse Care Manager in Integrated Care: A Systematic Report

    Get PDF
    Introduction: The collaborative care model (CCM) is an effective model for improving depression symptoms in patients in a primary care (PC) setting. An essential role in this model is the care manager (CM), and nurses have been effective in this role. However, there remains a question of how to best design, train, and implement this nurse CM role in PC. Objectives: The purpose of this review is to provide readers with a critical description of what processes for training and implementation of a collaborative nurse CM role have been be successful in the literature, specifically as it pertains to supporting patients with depression and chronic medical illnesses in an integrated PC setting. Methods: A literature review of PubMed, CINAHL, PsychInfo, Scopus, and the Cochrane Collaborative was conducted in October 2018. Discussion: Successful nurse CM interventions have included regular patient follow-up, symptom check-in, treatment monitoring, goal setting, and education. Psychological support techniques such as problem solving therapy, behavioral activation, and motivational interviewing have been useful in supporting patient care-plan engagement and goal achievement. Nurse CM training should support the successful implementation of the designed role. Conclusion: Nurse CMs have an opportunity to significantly impact depressive outcomes of patients with depression and long-term health conditions. Further research is needed to explore the potential that this nursing role has, as well as how to best operationalize this role

    A Community Conversation on Adolescent Pregnancy and Parenting Services: Networks of Support, Gatekeepers to Care, and Non-Compulsory Fathering in a Black Urban Community

    Get PDF
    This study employed Community-Based Participatory Research (CBPR) methods to document needs and capacity around adolescent pregnancy and parenting in one predominately Black, low-income urban community. Using an iterative focus group method, we engaged 60 participants in a two-day community conversation. Quantitative data from an enrollment questionnaire and qualitative transcripts of the discussions are analyzed. Our results indicate that the community’s greatest capacity lies in a network of women. Men tend to participate in parenting more holistically once formal paternity is established. Neighborhood women typically introduce adolescents to prenatal care, so delays in revealing the pregnancy to them serves as a barrier to accessing prenatal care. Overall, participants want health agencies to uphold their formal social contracts with the community, but to entrust informal services to community members who have the necessary insight and expertise to deliver support and information that is usable in their social context
