    Groundwater contributes an essential water supply to several communities and ecosystems in the Truckee River Basin. Water resource investigations were conducted through numerical modeling and comparisons to previous work to assess groundwater recharge in the Martis Valley watershed, which is an essential component to the Truckee River hydrographic region. A baseflow analysis was performed to relate annual baseflow to streamflow and precipitation. Results show that changes in groundwater fluctuations are driven by changes in precipitation, and baseflow response is affected by previous precipitation trends. It was estimated that baseflow is roughly one-sixth of mean annual precipitation. A novel method for constructing a hydrogeologic framework model was developed and applied to an integrated surface water-groundwater hydrologic model, GSFLOW, from which groundwater recharge locations and magnitudes were extracted. Model results supplemented previous work and provided enhanced conceptualizations of surface and groundwater interactions, as well as spatial and temporal recharge trends. Results show that the most significant recharge zones are low to mid-elevation stream channel and alluvial areas. During peak snowmelt periods, upper elevation alluvial areas also contribute significant recharge. The findings herein promote a more detailed understanding of groundwater recharge characteristics in high elevation, snow dependent, alpine catchments

    Big Parcels: Modernist Planning in Washington State History

    In anthropology’s spatial turn, cultural anthropologists directed portions of their attention to the spaces in which human habitation takes shape. This article concerns the large planned spaces configured in the Modernist era of the twentieth century. Utilizing a fieldwork-based methodology that draws on the ethnographic toolkit, analysis compares and contrasts three large planned spaces located in Washington State: the former site of the Northern State Mental Hospital in Sedro-Woolley, the location in central Spokane at which Expo 74 was hosted, and the rural location of the never-completed Satsop Nuclear Facility near Elma, Washington. Our analysis suggests the singular use for which these sites were once constructed poses challenges for reconfiguring them to contemporary use. Notably, those sites with interconnections to nearby communities, and those that conjure or draw upon a broader social memory of place, have fared better in their path to the present

    Developmental associations between victimization and body mass index from 3 to 10 years in a population sample

    In the current prospective study, we investigated (1) whether high and low BMI in early childhood puts a child at risk of victimization by their peers, and (2) whether being victimised increases BMI over the short- and long-term, independent of the effect of BMI on victimization. We also examined whether gender moderated these prospective associations. Participants were 1344 children who were assessed yearly from ages 3 -10 years as part of the Québec Longitudinal Study of Child Development (QLSCD). BMI predicted annual increases in victimization for girls aged 6 years and over; for boys aged 7 and 8 years of age, higher BMI reduced victimization over the school year. Further, victimization predicted annual increases in BMI for girls after age 6 years. When these short-term effects were held constant, victimization was also shown to have a three and five-year influence on annual BMI changes for girls from age 3 years. These short- and long-term cross-lagged effects were evident when the effects of family adversity were controlled. The findings support those from previous prospective research showing a link between higher BMI and victimization, but only for girls. Further, being victimised increased the likelihood that girls would put on weight over time, which then increased future victimization. The implications of these prospective findings for interventions are considered

    This work is licensed under a Creative Commons Attribution License (CC-BY-NC-SA) (http://creativecommons.org/licenses/by-nc-sa/4.0).Premise of the study: We isolated 15 polymorphic microsatellite markers from Vachellia farnesiana for use in population genetic studies to determine the native range of the species. Methods and Results: Initially, 454 shotgun sequencing was used to identify and design primers for 68 microsatellite loci. Of these, we trialed 47 loci in the target species, and 42 (89%) amplified a product of expected size. Fifteen of the 47 loci were screened for variation in 21 individuals from the native range of V. farnesiana in southern Mexico and 20 from northwestern Australia. Fourteen loci were polymorphic, with observed heterozygosity ranging from 0.026 to 1.00 (mean = 0.515) and two to 12 alleles per locus (average = 5.2). Cross-amplification was successful in four to 11 loci in three other Vachellia species. Conclusions: The new microsatellite loci will be useful in understanding genetic variation and investigating the role of human-mediated dispersal in the current distribution of V. farnesiana

    Women's perceptions of their healthcare experience when they choose not to breastfeed

    Research Question How do women who choose not to breastfeed perceive their healthcare experience? Method This qualitative research study used a phenomenographic approach to explore the healthcare experience of women who do not breastfeed. Seven women were interviewed about their healthcare experience relating to their choice of feeding, approximately four weeks after giving birth. Six conceptions were identified and an outcome space was developed to demonstrate the relationships and meaning of the conceptions in a visual format. Findings There were five unmet needs identified by the participants during this study. These needs included equity, self sufficiency, support, education and the need not to feel pressured. Conclusion Women in this study who chose not to breastfeed identified important areas where they felt that their needs were not met. In keeping with the Code of Ethics for Nurses and Midwives, the identified needs of women who do not breastfeed must be addressed in a caring, compassionate and just manner. The care and education of women who formula feed should be of the highest standard possible, even if the choice not to breastfeed is not the preferred choice of healthcare professionals

    Youth, caregiver, and prescriber experiences of antipsychotic-related weight gain

    Objectives. To explore the lived experience of youth, caregivers, and prescribers with antipsychotic medications. Design. We conducted a qualitative interpretive phenomenology study. Youth aged 11 to 25 with recent experience taking antipsychotics, the caregivers of youth taking antipsychotics, and the prescribers of antipsychotics were recruited. Subjects. Eighteen youth, 10 caregivers (parents), and 11 prescribers participated. Results. Eleven of 18 youth, six of ten parents, and all prescribers discussed antipsychotic-related weight gain. Participants were attuned to the numeric weight changes usually measured in pounds. Significant discussions occurred around weight changes in the context of body image, adherence and persistence, managing weight increases, and metabolic effects. These concepts were often inextricably linked but maintained the significance as separate issues. Participants discussed tradeoffs regarding the perceived benefits and risks of weight gain, often with uncertainty and inadequate information regarding the short- and long-term consequences. Conclusion. Antipsychotic-related weight gain in youth influences body image and weight management strategies and impacts treatment courses with respect to adherence and persistence. In our study, the experience of monitoring for weight and metabolic changes was primarily reactive in nature. Participants expressed ambiguity regarding the short- and long-term consequences of weight and metabolic changes

    A qualitative study of antipsychotic medication experiences of youth

    Objective: To explore the lived experience of youth who are prescribed antipsychotics. Methods: We conducted an interpretive phenomenology study of young people with recent experience of taking antipsychotics. Youth were interviewed and a staged approach was used for data analysis of transcriptions. We collected approximately 13 hours of audio from 18 youth aged 13 to 26 years between January and August of 2010. Results: Ambivalence was significant and antipsychotic adverse effects frequently tempered benefits. Both illness and antipsychotics had significant impacts on physical and mental wellbeing with adverse effects on relationships and functioning in various contexts (e.g., school). Stigma related to both antipsychotics and illness was also prominent. Participants' limited knowledge about their antipsychotics and pressure to conform within their youth culture and context affected decisions on starting, adhering to, and persisting with treatment. Conclusions: The lived experience of youth taking antipsychotics is complex and the benefits (e.g., symptom improvement) and consequences (e.g., adverse effects) associated with antipsychotics affect all facets of life. More research is needed to better understand youth priorities in treatment decisions and whether youth who demonstrate substantive gaps in their knowledge about antipsychotics are truly given the opportunity to be informed and engage in management decisions including whether to initiate, persist with, and discontinue treatments
