Infusing Service-Learning into Academic ABC\u27s: Awareness, Behavior, Community Collaboration

As part of a Science, Technology, Engineering, and Mathematics (STEM) Service-Learning grant, a service-learning project was integrated into two college programs. The overall purpose of this project was to address identified community needs concerning nutrition, health-related issues, food security, and food sustainability. First-year college students developed and implemented a community nutrition survey, and created a list of community resources. These students then shared their survey results and overall impressions of the experience with public health nursing students, who then addressed community needs through a variety of service-learning interventions. Some of these interventions included mobilizing church volunteers to increase the availability of fresh produce to the local food shelf, and providing sweat equity to upgrade and maintain community gardens. Student reflections illustrated an increased awareness of food issues, particularly for low-income families. After the service-learning experience, students expressed a greater interest in serving their community and making a difference. Students strengthened the community’s commitment to meet mutual food needs by bringing in additional collaborators to work with their partnering agencies. Students learned not only about food—they learned about themselves, the community, and the results that collaboration can bring

Overwintering Locations, Migrations, and Fidelity of Radio-Tagged Dolly Varden in the Hulahula River, Arctic National Wildlife Refuge, 2007–09

Essential overwintering habitats for anadromous Dolly Varden Salvelinus malma on Alaska’s North Slope appear to be limited to a small number of perennial springs, primarily in eastern Brooks Range drainages. Because future petrochemical development in the region continues to be a possibility, and development would require large quantities of freshwater, we sought to identify and document the overwintering areas used by Dolly Varden in the Hulahula River, eastern Brooks Range. In August 2007, we implanted 52 Dolly Varden with multi-year radio transmitters at a known overwintering area in the lower Hulahula River. Other wintering areas were located during 11 aerial surveys conducted over the next 2.5 years. A stationary receiver located in the lower Hulahula River provided migration timing information. Radio-tagged Dolly Varden used four discrete areas with perennial springs for overwintering in the Hulahula River drainage. The springs, totaling approximately 12 km in stream length, were located between river km 40 and 105. Radio-tagged Dolly Varden migrated downstream on their way to the Beaufort Sea in early June. Most tagged fish known to have survived the summer at sea returned to the Hulahula River during late July and August, but seven fish overwintered in other North Slope drainages. Within the Hulahula River drainage, 15 fish overwintered in more than one area during the three winters of the project, but only the four identified perennial spring areas were used. These data clearly indicate that the perennial springs in the Hulahula River are essential overwintering habitats for Dolly Varden.Les aires de concentration hivernales essentielles du Dolly Varden Salvelinus malma anadrome sur la North Slope de l’Alaska semblent limitées à un petit nombre de sources pérennes, principalement dans les bassins hydrographiques de l’est de la chaîne de Brooks. Puisqu’il est toujours possible qu’il y ait des aménagements pétrochimiques dans la région et que ceux-ci demanderaient de grandes quantités d’eau douce, nous avons tâché de déterminer les aires de concentration hivernales du Dolly Varden dans la rivière Hulahula faisant partie de l’est de la chaîne de Brooks, et nous les avons répertoriées. En août 2007, nous avons installé des émetteurs radio pluriannuels sur 52 poissons Dolly Varden dans une aire de concentration hivernale connue faisant partie de la rivière Hulahula inférieure. D’autres aires de concentration hivernales ont été repérées grâce à 11 levés aériens effectués au cours des 2,5 années qui ont suivi. Un récepteur fixe situé dans la rivière Hulahula inférieure nous a permis de relever des données sur le moment de la migration. Les Dolly Varden dotés d’émetteurs radio ont utilisé quatre sources discrètes où se trouvent des sources pérennes pour passer l’hiver, dans le bassin versant de la rivière Hulahula. Les sources, qui s’étendent sur une douzaine de kilomètres de longueur, étaient situées entre les kilomètres 40 et 105 de la rivière. Les Dolly Varden munis d’émetteurs radio ont migré en aval, en route vers la mer de Beaufort au début juin. La plupart des poissons avec émetteur ont survécu l’été à la mer et ont regagné la rivière Hulahula vers la fin de juillet et en août, mais sept poissons ont passé l’hiver dans d’autres bassins versants de la North Slope. Dans le bassin versant de la rivière Hulahula, 15 poissons ont passé l’hiver dans plus d’une aire au cours des trois hivers visés par le projet, mais seules les quatre sources pérennes déterminées ont été utilisées. Ces données indiquent clairement que les sources pérennes de la rivière Hulahula sont des aires de concentration hivernales essentielles pour le Dolly Varden

Leaving Residual Varus Alignment After Total Knee Arthroplasty Does Not Improve Patient Outcomes

Background Recent popularity of kinematic alignment and constitutional varus has caused some surgeons to leave varus limbs in residual varus after total knee arthroplasty (TKA). This study assessed whether if patients left in residual varus have improved outcomes compared with those fully corrected to neutral alignment. Methods A retrospective review of 361 consecutive primary TKAs was performed. Anatomic tibiofemoral alignment was measured and knees were categorized as neutral, varus, or valgus. Modern Knee Society scores and University of California Los Angeles Activity Level scores were collected at minimum 1-year follow-up. Results After exclusions for confounds and loss to follow-up, 262 knees were available for analysis, 67% (176) of which were preoperatively varus. Sixty-six percent of varus knees were corrected to neutral, 25.6% were left in residual varus, and 8.5% were corrected to valgus. Median Knee Society objective scores at latest follow-up were greater in knees corrected to neutral (97), followed by knees corrected to varus (95), and valgus (93; P = .025), but post hoc comparisons between pairs of medians were not significant. There was no difference between groups in any other outcome measure (P ≥ .245) or the amount of improvement from baseline (P ≥ .423). Sixty percent of native varus patients corrected to neutral, 64% of those corrected to varus, and 40% of those corrected to valgus reported that their knee felt normal (P = .193). Conclusion Findings fail to support the notion that leaving varus knees in residual varus will improve outcomes and pain. Caution is advised when leaving limbs in residual varus after TKA

Intermittent preventive treatment for malaria and anaemia control in Tanzanian infants; the development and implementation of a public health strategy.

Minimizing the time between efficacy studies and public health action is important to maximize health gains. We report the rationale, development and implementation of a district-based strategy for the implementation of intermittent preventive treatment in infants (IPTi) for malaria and anaemia control in Tanzania. From the outset, a research team worked with staff from all levels of the health system to develop a public-health strategy that could continue to function once the research team withdrew. The IPTi strategy was then implemented by routine health services to ensure that IPTi behaviour-change communication materials were available in health facilities, that health workers were trained to administer and to document doses of IPTi, that the necessary drugs were available in facilities and that systems were in place for stock management and supervision. The strategy was integrated into existing systems as far as possible and well accepted by health staff. Time-and-motion studies documented that IPTi implementation took a median of 12.4 min (range 1.6-28.9) per nurse per vaccination clinic. The collaborative approach between researchers and health staff effectively translated research findings into a strategy fit for public health implementation

The Sandia MEMS Passive Shock Sensor : dormancy and aging.

This report presents the results of an aging experiment that was established in FY09 and completed in FY10 for the Sandia MEMS Passive Shock Sensor. A total of 37 packages were aged at different temperatures and times, and were then tested after aging to determine functionality. Aging temperatures were selected at 100 C and 150 C, with times ranging from as short as 100 hours to as long as 1 year to simulate a predicted aging of up to 20 years. In all of the tests and controls, 100% of the devices continued to function normally

Conference Scheduling Undermines Diversity Efforts

We assessed diversity-focused programming at 29 major biology conferences from 2010 to 2019, noting events tailored to three underrepresented and marginalized groups in biology: women, ethnic and racial minority groups, and the LGBTQ+ community (see Supplementary Information for further methods). Since 2010, diversity-focused events have become more common but frequently address only a subset of URG communities. In general, the percentage of conferences with diversity-focused events increased from 75% in 2019. On average, women were the most frequent focus of these events and the LGBTQ+ community was the least frequent focus (Fig. 1a)

Shock margin testing of a one-axis MEMS accelerometer.

Shock testing was performed on a selected commercial-off-the-shelf - MicroElectroMechanical System (COTS-MEMS) accelerometer to determine the margin between the published absolute maximum rating for shock and the 'measured' level where failures are observed. The purpose of this testing is to provide baseline data for isolating failure mechanisms under shock and environmental loading in a representative device used or under consideration for use within systems and assemblies of the DOD/DOE weapons complex. The specific device chosen for this study was the AD22280 model of the ADXL78 MEMS Accelerometer manufactured by Analog Devices Inc. This study focuses only on the shock loading response of the device and provides the necessary data for adding influence of environmental exposure to the reliability of this class of devices. The published absolute maximum rating for acceleration in any axis was 4000 G for this device powered or unpowered. Results from this study showed first failures at 8000 G indicating a margin of error of two. Higher shock level testing indicated that an in-plane, but off-axis acceleration was more damaging than one in the sense direction

Return to Sport After Turf Toe Injuries: A Systematic Review and Meta-analysis

A grant from the One-University Open Access Fund at the University of Kansas was used to defray the author's publication fees in this Open Access journal. The Open Access Fund, administered by librarians from the KU, KU Law, and KUMC libraries, is made possible by contributions from the offices of KU Provost, KU Vice Chancellor for Research & Graduate Studies, and KUMC Vice Chancellor for Research. For more information about the Open Access Fund, please see http://library.kumc.edu/authors-fund.xml.Background: The prevalence of turf toe injuries has increased in recent years. However, uncertainty remains as to how to optimally treat turf toe injuries and the implications that the severity of the injury has on outcomes, specifically return to sport (RTS). Purpose: To determine RTS based on treatment modality and to provide clinicians with additional information when comparing operative versus nonoperative treatment of turf toe injuries in athletes. Study Design: Systematic review; Level of evidence, 4. Methods: A systematic review and meta-analysis was performed using the PubMed/Ovid MEDLINE/PubMed Central databases (May 1964 to August 2018) per PRISMA-IPD (Preferred Reporting Items for Systematic Reviews and Meta-Analyses of Individual Participant Data) guidelines. RTS, treatment, severity of injury, athletic position, and sport were recorded and analyzed. Results: Of 858 identified studies, 12 met the criteria for the final meta-analysis. The studies included 112 athletes sustaining a total of 121 turf toe injuries; 63 (52.1%) of these injuries were treated surgically, while 58 (47.9%) were treated nonoperatively, and 53.7% were classified by the grade of injury (grade I, n = 1; grade II, n = 9; grade III, n = 55). Overall, 56 (46.3%) injuries could not be classified based on the data provided and were excluded from the final analysis. The median time to RTS for patients treated nonoperatively was 5.85 weeks (range, 3.00-8.70 weeks) compared with 14.70 weeks (range, 6.00-156.43 weeks) for patients treated surgically (P < .001); however, there was variability in the grade of injury between the 2 groups. Similarly, patients who sustained grade II injuries returned to sport more quickly (8.70 weeks) than patients who had a grade I (13.04 weeks) or grade III injury (16.50 weeks) (P = .016). The amount of time required to RTS was significantly influenced by the athlete’s level of play (16.50 weeks for both high school and college levels; 14.70 weeks for professional level) (P = .018). Conclusion: The time to RTS for an athlete who suffers from a turf toe injury is significantly influenced by the severity of injury and the athlete’s level of competition. Professional athletes who suffer from turf toe injuries RTS sooner than both high school and college athletes. However, there are a limited number of high-level studies evaluating turf toe injuries in the athletic population. Further research is necessary to clearly define the appropriate treatment and RTS protocols based on sport, position, and level of play

2014 OWL Usability Report

Consisting of six sections, this report was completed by groups composed of students registered for ENGL515: Advanced Professional Writing. Studying the concepts of User-centered Design, Usability, and User Experience Design (UxD), the students offer this report and accompanying redesign materials for the use of Purdue’s Online Writing Lab (OWL). It is presented to Tammy S. Conard-Salvo, Associate Director of the OWL, in support of user research conducted throughout fall 2014 and into spring 2015. This report is aimed at improving the user’s experience of the OWL and as such offers methods of learning more about the site’s audience and both responding to user need and developing methods of gathering data about these users and their needs. The first task, then, is to collect data about users using a demographic questionnaire. Then, this report recommends developing a series of online research tools that will reveal users’ preferences before performing any redesign. We forecast potential for primary research developing and reporting the results of developing user measurement tools that can be used remotely through Qualtrics
