A Comparison of Soil Moisture and Hillslope-Stream Connectivity Between Aspen and Conifer-Dominated Hillslopes of a First Order Catchment in Northern Utah

Mountain headwater catchments in the semi-arid Intermountain West are important sources of surface water because these high elevations receive more precipitation than neighboring lowlands. The hydrology of these mountain catchments is especially important as the region faces water shortages and conflicts. Conifer encroachment on aspen stands has been observed across the western US and can result in a decline in water yield. The overall objective of this study was to further our understanding of hillslope-stream connectivity in a headwater catchment of Northern Utah and any observable differences in this connection between aspen and conifer hillslopes. Hillslopes are the fundamental unit of a watershed. Therefore understanding processes at the hillslope scale is pertinent to managing valuable water resources. However, hillslope hydrology is understudied in the snow-driven, semi-arid west, leaving a gap in our knowledge of how watersheds function. This thesis focuses on how and when hillslope water contributes to stream water: hillslope-stream connectivity. Its specific objectives are (1) to compare peak snow accumulation under aspen and conifer stands, (2) to determine if shallow soil moisture shows organized patterns, indicating hillslope-connectivity and compare these patterns between vegetation types, (3) to examine hillslope-stream connectivity within deep layers of the soil profile and compare times of connectivity between vegetation types and (4) to find any thresholds past which hillslope-stream connectivity begins

Superstars and Misfits: Two Pop-trends in the Gender Culture of Contemporary Evangelicalism

This paper examines gender in two forms of mediated contemporary Protestant evangelicalism in the United States: a male-dominated punk network, called Misfits United, and a women’s group studying Beth Moore’s Bible study, It’s Tough Being a Woman (ITBAW). While the appearance and performance styles of these two groups are drastically different, both support gender hierarchies in similar ways. Misfits United and Moore’s ITBAW present the gender of their Christian God as flexible, even transformative, and in effect open up discursive space to conceptualize gender on non-traditional grounds. Paradoxically, however, both reinforce traditional gender roles by emphasizing what distinguishes God from His creation: the gendered constraints of human biology

Language Style Matching in Older Couples and Marital Satisfaction

Research on marital communication has focused on nonverbal behaviors (e.g., affect), leaving specific word use relatively unexplored. Recent work, however, suggests that similarity in function words (e.g., articles) may be associated with relational functioning in younger couples. We explored if this language style matching (LSM) also occurred in more established relationships and whether it was related to marital satisfaction within a sample of 64 older adult married couples. Using a dyadic, two-wave, observational research design, our results suggest that LSM is highly prevalent in older couples’ conversations across three different tasks (reminiscence, problem solving, and health support). Only LSM during reminiscence, however, was related to wives’ concurrent marital satisfaction. We considered implications for future research and for potential clinical interventions targeting language and communication in older adults

One Foundation's Experience with Primary and Integrated Care Grantmaking: Lessons on Leverage and Policy Change

Significant changes in health care practice usually require changes in compensation practice -- and may also require changes in licensing (of facilities and/or professions), certification and professional training. This is important work that requires a long-term commitment. And it may give rise to push-back from various sources invested in the current state of affairs:* Professionals, not wanting others to be licensed to perform similar services at lower reimbursement rates* Payers, not wanting to open a door to new categories of reimbursable services* Training institutions reluctant to alter curriculum, until it is clear that a new approach has staying powerFoundations are in a powerful position to speak out for change, as we "don't have a dog in the fight." That neutrality can be our strength, particularly as we become known for speaking clearly and from a basis in factual information and evidence-based approaches

Star Formation History since z = 1.5 as Inferred from Rest-Frame Ultaviolet Luminosity Density Evolution

We investigate the evolution of the universal rest-frame ultraviolet luminosity density from z = 1.5 to the present. We analyze an extensive sample of multicolor data (U', B, V = 24.5) plus spectroscopic redshifts from the Hawaii Survey Fields and the Hubble Deep Field. Our multicolor data allow us to select our sample in the rest-frame ultraviolet (2500 angstrom) over the entire redshift range to z = 1.5. We conclude that the evolution in the luminosity density is a function of the form (1+z)^{1.7\pm1.0} for a flat lambda cosmology and (1+z)^{2.4\pm1.0} for an Einstein-de Sitter cosmology.Comment: 12 pages, 7 figs, 5 tables, submitted to A

Playing with or next to? The nuanced and complex play of children with impairments

This paper examines play as a fundamental children’s activity, giving particular attention to the inclusion of children with impairments at play and children’s shared constructions of their playworlds. Children with impairments are customarily portrayed as incompetent, unskilled or deficient in their play, thus being positioned on the margins (or, as ‘who’s out’?) of mainstream discourses. On the other hand, non-impaired children are usually regarded as competent players, who play in ‘normal’ ways (as ‘who’s in’?). Little attention is afforded to noticing skilful or proficient play by children with impairments and including their perspectives in play research. The Social Model of Childhood Disability offers a perspective for considering ‘disabled childhoods’ and framing enquiry into the culturally-constructed playworlds of children with impairments. Evidence from two ethnographic studies that examine children with impairments at play is discussed, employing vignettes that utilise data from researcher and teacher observation notes. The authors document specific play interactions related to individual experiences and interests and explore how children work together and alone to create meaningful play interactions. The notion that play for children is a mutual, shared and inclusive cultural experience is supported in this paper

Praxis with Self-Advocates: Exploring Participatory Video as Radical Incrementalism

In this article, the authors report selected findings from a larger study where self-advocates from the disability rights movement created a series of short videos as part of a participatory research project. Self-advocates subsequently integrated these videos into a greater community organizing initiative. While the research process of this study has been published elsewhere, this piece will explore the idea of bridging participatory video, a collaborative research methodology, with community-based advocacy initiatives. The authors contend that this presents an opportunity for radical incrementalism in which to create a praxis driven predominantly by the voices on the margins versus the academic elite. In this article, a link to one of the videos is also included alongside participant reflections on the research process

Promoting Environments that Measure Outcomes: Partnerships for Change

This paper describes the development of the PrEMO© (Promoting Environments that Measure Outcomes) program. PrEMO© is an innovative model promoting evidence-based practice (EBP) while developing capacity and quality of Level II fieldwork placements. The PrEMO© program is described from initiation to completion, including development of site-specific learning objectives, the twelve week schedule and the role of faculty mentorship. Occupational therapy (OT) students, and university OT program faculty including academic fieldwork coordinators, partner with fieldwork educators at the site to implement EBP using a data-driven decision making (DDDM) process to guide the development of evidence-based practices. PrEMO© appears to be a useful strategy for building Level II fieldwork capacity and enhancing student and fieldwork educators’ knowledge and skills about EBP and outcome measurement in routine OT practice

Altering the Size Distribution of Influenza Virion Populations [Poster]

Harry Smith Vacation Studentship Laboratory-adapted influenza viruses produce predominantly spherical virions. In contrast, clinical and veterinary isolates produce a mixture of virions of different sizes, from 0.1 µm spheres to filaments which can reach tens of microns in length. Filamentous influenza virions were discovered in 1946, but the bulk of influenza research has analysed only spherical forms of the virus and the role of filaments in influenza infections is unclear. Functional studies of filaments require the development of methods to manipulate the ratio of spherical to filamentous virions, and we reasoned that this could be achieved by filtration. To test this, we infected MDCK cells with the filamentous Udorn strain of influenza A virus. We collected virus-containing growth media and passed this through filters with 5 µm, 0.45 µm and 0.2 µm pores. Filtrates and unfiltered virus were compared, using Western blotting to measure their protein composition, plaque assays to measure their infectivity and negative stain transmission electron microscopy to measure individual particle sizes. We found that filtration through a filter with 5 µm pores had little effect on composition, infectivity and the ratio of spherical to filamentous particles. In contrast, sub-micron filters, particularly those with 0.2 µm pores, caused a general depletion of virions but increased the sphere to filament ratio. We therefore concluded that sub-micron pore sizes can be used to preferentially remove filaments from populations of pleomorphic influenza virions, providing a useful tool for subtractive studies of the contribution filaments make to influenza virus infections
