Exploring the feasibility of international collaboration and relationship building through a virtual partnership scheme

International collaboration is an under-studied component of the Scholarship of Teaching and Learning (SoTL). This study sheds light on the process of international collaboration by illustrating an exploratory approach to the process of forming and maintaining collaborative partnerships. Participants in this study were put into pairs (each one comprised of one individual from the University of Glasgow and another from the University of Wisconsin System) and asked to participate in email correspondence over the course of one year. The text of participants’ emails was pooled and analyzed through a general inductive approach using NVivo software. The study, though small in nature, helps to illustrate and further understand international collaborative relationships. We offer suggestions for future international collaborations and discuss the implications of emphasizing such partnerships within SoTL

College Debt: An Exploratory Study of Risk Factors Among College Freshmen

The goals of this study are to examine the relationships between loan knowledge, money management skills, debt tolerance attitudes, and student income potential to their willingness to incur educational debt at a mid-western university. The current study showed that freshmen students lacked personal and general loan knowledge and had unrealistic expectations of future income at graduation

Early weight gain predicts treatment response in adolescents with anorexia nervosa enrolled in a family‐based partial hospitalization program

ObjectiveImproved treatment outcome in family‐based treatment (FBT) for anorexia nervosa (AN) is predicted by weight gain occurring early in the course of treatment (i.e., about 4 lbs by week 4). Although prior work suggests that early weight gain in higher levels of care (e.g., partial hospitalization programs [PHP]) predicts weight restoration at discharge, no study has examined the specific rate of gain within FBT‐informed PHP programs that best predicts treatment response.MethodThis study examined rate of weight gain in pounds and percent expected body weight (EBW) that predicts positive outcome in 70 patients (M age = 15.49 years, SD = 2.56) with AN who were enrolled in a family‐based PHP.ResultsReceiver operator characteristic analyses demonstrated that changes in %EBW during weeks 2–5 were more useful than changes in weight in predicting positive outcome. Gaining at least 8.9 pounds or over 8% of EBW in the first 4 weeks of treatment significantly predicted positive outcome.DiscussionFindings suggest that positive outcome in an FBT‐informed PHP is predicted by rapid weight gain in the initial weeks of treatment. Research is needed to identify specific family and patient characteristics that facilitate weight gain and to develop corresponding interventions to improve outcome.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/154930/1/eat23248_am.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/154930/2/eat23248.pd

Simulated Waste for Leaching and Filtration Studies--Laboratory Preparation Procedure

This report discusses the simulant preparation procedure for producing multi-component simulants for leaching and filtration studies, including development and comparison activities in accordance with the test plan( ) prepared and approved in response to the Test Specification 24590-WTP-TSP-RT-06-006, Rev 0 (Smith 2006). A fundamental premise is that this approach would allow blending of the different components to simulate a wide variety of feeds to be treated in the Hanford Tank Waste Treatment and Immobilization Plant (WTP). For example, a given feed from the planned feed vector could be selected, and the appropriate components would then be blended to achieve a representation of that particular feed. Using the blending of component simulants allows the representation of a much broader spectrum of potential feeds to the Pretreatment Engineering Platform (PEP)

Elevated CO2 did not stimulate stem growth in 11 provenances of a globally important hardwood plantation species

Elevated atmospheric carbon dioxide (eCO2) often enhances rates of photosynthesis leading to increased productivity in trees. In their native habitats in Australia, eucalypts display considerable phenotypic plasticity in response to changes in environmental conditions. Little is known whether this plasticity can be harnessed effectively under future atmospheric eCO2 conditions and be used to identify provenances with superior growth. Here, we report two experiments that assessed the physiological and growth responses of Eucalyptus grandis—one of the world's most important hardwood plantation species—to eCO2. We used 11 provenances from contrasting climates. Our selection was based on site-specific information of long-term temperature and water availability. In Experiment 1, four provenances exhibited significant variation in light-saturated photosynthetic rates (Asat), stomatal conductance (gs), and concentrations of non-structural carbohydrates in leaves, stems and roots when grown under ambient CO2 (aCO2). Biomass of leaves, stems and roots varied significantly and were negatively correlated with mean annual temperature (MAT) at seed origin, indicating that provenances from cooler, wetter climates generally produced greater biomass. Yet, stem growth of these provenances was not stimulated by eCO2. Given the vast environmental gradient covered by provenances of E. grandis, we expanded the selection from four to nine provenances in Experiment 2. This allowed us to validate results from Experiment 1 with its small selection and detailed measurements of various physiological parameters by focusing on growth responses to eCO2 across a wider environmental gradient in Experiment 2. In Experiment 2, nine provenances also exhibited intraspecific differences in growth, but these were not related to climate of origin, and eCO2 had little effect on growth traits. Growth responses under eCO2 varied widely across provenances in both experiments, confirming phenotypic plasticity in E. grandis, though responses were not systematically correlated with climate of origin. These results indicate that selection of provenances for improved stem growth of E. grandis under future eCO2 cannot be based solely on climate of origin, as is common practice for other planted tree species

The kinetics and acoustics of fingering and note transitions on the flute

Motion of the keys was measured in a transverse flute while beginner, amateur and professional flutists played a range of exercises. The time taken for a key to open or close is typically 10 ms when pushed by a finger or 16 ms when moved by a spring. Delays between the motion of the fingers were typically tens of ms, with longer delays as more fingers are involved. Because the opening and closing of keys will never be exactly simultaneous, transitions between notes that involve the movement of multiple fingers can occur via several possible pathways with different intermediate fingerings. A transition is classified as `safe' if it is possible to be slurred from the initial to final note with little perceptible change in pitch or volume. Some transitions are `unsafe' and possibly involve a transient change in pitch or a decrease in volume. In transitions with multiple fingers, players, on average, used safe transitions more frequently than unsafe transitions. Professionals exhibited smaller average delays between the motion of fingers than did amateurs

Development and Characterization of Gibbsite Component Simulant

According to Bechtel National, Inc.’s (BNI’s) Test Specification 24590-PTF-TSP-RT-06-006, Rev 0, "Simulant Development to Support the Development and Demonstration of Leaching and Ultrafiltration Pretreatment Processes," simulants for boehmite, gibbsite, and filtration are to be developed so they can be used in subsequent bench and integrated testing of the leaching/filtration processes for the River Protection Project-Waste Treatment and Immobilization Plant (RPP-WTP). These simulants will then be used to demonstrate the leaching process and to help refine processing conditions that may impact safety basis considerations (Smith 2006). This report documents PNNL’s results of the gibbsite simulant development

Substrate Type Determines Metagenomic Profiles from Diverse Chemical Habitats

Environmental parameters drive phenotypic and genotypic frequency variations in microbial communities and thus control the extent and structure of microbial diversity. We tested the extent to which microbial community composition changes are controlled by shifting physiochemical properties within a hypersaline lagoon. We sequenced four sediment metagenomes from the Coorong, South Australia from samples which varied in salinity by 99 Practical Salinity Units (PSU), an order of magnitude in ammonia concentration and two orders of magnitude in microbial abundance. Despite the marked divergence in environmental parameters observed between samples, hierarchical clustering of taxonomic and metabolic profiles of these metagenomes showed striking similarity between the samples (>89%). Comparison of these profiles to those derived from a wide variety of publically available datasets demonstrated that the Coorong sediment metagenomes were similar to other sediment, soil, biofilm and microbial mat samples regardless of salinity (>85% similarity). Overall, clustering of solid substrate and water metagenomes into discrete similarity groups based on functional potential indicated that the dichotomy between water and solid matrices is a fundamental determinant of community microbial metabolism that is not masked by salinity, nutrient concentration or microbial abundance.</p
