Speech and language therapy students’ experience of peer assisted learning:Undergraduates investigate PAL as a means of enhancing academic and professional development

The implementation of Peer Assisted Learning (PAL) on healthcare courses in Higher Education Institutions has been explored in a number of studies. This paper presents research into the experience of PAL on a BSc Speech & Language Therapy (SLT) programme. The research was conducted by final year undergraduate SLT students to form the basis for their final dissertations. The focus for their research was on the effects of PAL on academic and professional development for both mentees and mentors on the same course. Data were generated from standard PAL evaluations and focus groups. Findings indicate that mentees benefit from PAL in terms of their university experience and learning. Mentors benefited from opportunities to develop and practice skills for their future employment. Engagement with PAL is attributed to its structured yet informal nature and the enthusiasm of the mentors. However, the collaborative nature of PAL takes time to develop, impacting on the behaviours of both mentees and mentors. Overall PAL offers mentees and mentors opportunities which enhance their academic learning and professional development

EVALUATING CHEMICAL DETERRENCE AT TWO SPATIAL SCALES: THE EFFECTIVENESS OF CHEMICAL DETERRENCE FOR SANDHILL CRANES IN CORNFIELDS

From 2006 through 2008, 9,10 anthraquinone (sold as Avitec™) was used as a deterrent on planted corn seed in Minnesota, Wisconsin, and Michigan. ICF conducted field trials in Wisconsin to determine efficacy of Avitec™ to repel sandhill cranes (Grus canadensis) from germinating corn. We assessed crane use at 2 levels: between and within habitats by crane population surveys to determine crane use of fields, and corn density surveys to assess possible damage within fields. In addition, corn seed samples were taken to assess amount of active ingredient on treated corn seeds in the ground. In 2008 the concentrations of Avitec™ on seed obtained from powder treatments (as compared to liquid treated) were generally lower. Where concentration of Avitec™ on the corn seeds was adequate (liquid or powder), it successfully deterred crane herbivory even though crane use of the fields remained high. Non-treated fields had higher damage as crane use increased, whereas treated fields had low or no damage, even with increased crane use. An effective deterrent is a win-win situation for both cranes and farmers. Its use protects a valuable crop while allowing cranes to access critical food items in cultivated fields, which also confers a benefit to the farmer (i.e., consumption of crop pests). Farmers can solve the problem more economically on their own without handling toxic seed treatments. Successful solutions such as this example are critical for advancing wildlife conservation on private lands

THE IMPACT OF MARKING ON CRANES: AN ISSUE PAPER

As crane researchers and conservationists, our overarching objective is to learn and gather information about our study subjects while doing as little harm as possible. New technologies may be emerging too rapidly for researchers to assess the effectiveness or potential adverse effects of the devices, despite the ease and increasing accuracy of the information they provide. Researchers need to be able to gather information to answer various questions in a way that balances ethics and expense. With marking of cranes as a focal point, we discuss issues surrounding crane research based on various techniques, some health issues that are a direct result of marking cranes, and consultation with telemetry companies to improve design of devices to be deployed on cranes. We submit a Call to Action: create a global crane research working group under the oversight of the International Union for Conservation of Nature (IUCN) Crane Specialist Group (CSG), a group dedicated to promoting the study and conservation of the world’s 15 crane species

TESTING THREE CHEMICALS FOR DETERRING CROP DAMAGE BY CRANES

Damage to planted corn seed by cranes has the potential to cause great economic loss in areas where both intersect. In 2000 the International Crane Foundation (ICF) tested limonene (LIM), methyl anthranilate (MA), and 9,10-anthraquinone (AQ) as possible replacements for the insecticides lindane and diazinon that had been used as deterrents to cranes damaging corn seed and seedlings. LIM, MA, and AQ lowered germination rates (down to 85, 90, and 92%, respectively) as compared to a germination rate of 96% in untreated corn. A 1.0% solution of AQ was effective as a crane deterrent, while LIM and MA were not. Both LIM and MA metabolized in the soil too quickly to be effective during the entire period when corn seedlings were vulnerable to crane herbivory. In 2001, a 0.5% concentration of AQ in 2 different soils (sand and organic) was tested in 2 different time periods (trial 1, 15 May to 14 June; trial 2, 26 June to 7 July 2). The concentration of AQ did not degrade to below effective levels in either soil type or in either time period. In all trials, AQ concentration of 0.5% prevented crane herbivory. Crane response to AQ-treated corn was to continue foraging in fields without damaging the planted crop. We believe AQ is an effective chemical deterrent and will prove useful for preventing crane damage to planted corn

Does fish oil during pregnancy help prevent asthma in kids?

Does fish oil during pregnancy help prevent asthma in kids? The evidence on fish oil has been mixed, but this study affirms its benefits--in certain women. PRACTICE CHANGER: Fish oil supplementation taken by women in the third trimester of pregnancy can reduce the risk of persistent wheeze, asthma, and infections of the lower respiratory tract in their children.Authors: Dana Neutze, MD, PhD; Kelly Lacy Evans, MD; Marianne Koenig, PharmD, BCPS; Gregory Castelli, PharmD, BCPS, BC-ADM; Anne Mounsey, MD Department of Family Medicine, University of North Carolina at Chapel Hill (Drs.

Shocked POststarbust Galaxy Survey I: Candidate Poststarbust Galaxies with Emission Line Ratios Consistent with Shocks

[Abridged] The Shocked POststarburst Galaxy Survey (SPOGS) aims to identify transforming galaxies, in which the nebular lines are excited via shocks instead of through star formation processes. Utilizing the OSSY measurements on the Sloan Digital Sky Survey Data Release 7 catalog, we applied Balmer absorption and shock boundary criteria to identify 1,067 SPOG candidates (SPOGs*) within z=0.2. SPOGs* represent 0.2% of the OSSY sample galaxies that exceed the continuum signal-to-noise cut (and 0.7% of the emission line galaxy sample). SPOGs* colors suggest that they are in an earlier phase of transition than OSSY galaxies that meet an E+A selection. SPOGs* have a 13% 1.4GHz detection rate from the Faint Images of the Radio Sky at Twenty centimeters survey, higher than most other subsamples, and comparable only to low-ionization nuclear emission line region hosts, suggestive of the presence of active galactic nuclei. SPOGs* also have stronger NaD absorption than predicted from the stellar population, suggestive of cool gas being driven out in galactic winds. It appears that SPOGs* represent an earlier phase in galaxy transformation than traditionally selected poststarburst galaxies, and that a large proportion of SPOGs* also have properties consistent with disruption of their interstellar media, a key component to galaxy transformation. It is likely that many of the known pathways to transformation undergo a SPOG phase. Studying this sample of SPOGs* further, including their morphologies, active galactic nuclei properties, and environments, has the potential for us to build a more complete picture of the initial conditions that can lead to a galaxy evolving.Comment: 19 pages, 19 figures, 3 tables, accepted to ApJ Supplements (Apr 13), full sample is available on www.spogs.or

Poster Abstract: Crane Charades: Behavior Identification via Backpack Mounted Sensor Platforms

The Whooping Crane is an endangered species native to North America and there are approximately 575 in existence. There have been recent efforts to provide ecologists with a tool to study the multifaceted behavior of the endangered species. Like many species, cranes display distinctly identifiable movements while being threatened, acting territorial, migrating, or preening. The preliminary experiments described in this poster provide evidence that sensor data presented by a novel sensing platform, the CraneTracker, can be used to identify crane behaviors on-board. With the ability to identify these behaviors, ecologists will have a more granular insight on what occurs during a crane’s life on a daily basis

The Whooping Crane in Mexico: Past, Present, and Future?

We reviewed ornithological, historic, anthropological, and archaeological records for evidence of whooping cranes (Grus americana) in Mexico. Records of whooping cranes in Mexico span 88 years (1863-1951) and cluster in 3 areas. Wintering records come from the northern highlands (Durango, and possibly Chihuahua), the central highlands (Guanajuato, Jalisco), and northeastern Tamaulipas, where the bird was also found in summer and might have bred. Later records (1970’s and 1980’s) of whooping cranes in the northern highlands are from individual birds released into the experimental migratory population that formerly migrated from Idaho to New Mexico, USA. Many of the wetlands used by whooping cranes remain and, though faced with a variety of threats, are conservation priority areas and some are already protected. We suggest 3 scenarios by which whooping cranes might return to winter in Mexico. The first 2 involve dispersal by birds wintering at the Aransas National Wildlife Refuge, Texas, USA, by either population growth or ecosystem changes or degradation (e.g., climate change, reduced freshwater inflows) at the refuge. Finally, reintroduction of a migratory population might target part of Mexico as a wintering area. We encourage investigation of wetlands in Mexico, especially in northeastern Tamaulipas for their potential as future wintering areas. Our preliminary survey of historic Spanish language publications covering the 1500’s to early 1600’s found clear references to cranes in which, for example, cranes are described feeding with geese in grain fields. Cranes are mentioned in accounts of the DeSoto and Coronado expeditions as well as the travels of Bishop Alonso de la Mota y Escobar. Unfortunately, these accounts do not adequately describe the birds for species identification. Only, the Florentine Codex by Fray Bernardino de Sahagun provides a description of the sandhill crane (G. canadensis) from near Mexico City at the time of Spanish conquest of the Aztecs. Continued searches of early Spanish language publications might yield more information of the historic distribution of cranes in Mexico

ENDOPARASITES OF GREATER SANDHILL CRANES IN SOUTH-CENTRAL WISCONSIN

Windingstad and Trainer (1977) used both fecal sampling and postmortem examinations to document the occurrence of parasites in greater sandhill cranes (Grus canadensis tabida) from Wisconsin in the fall. We conducted repeated fecal sampling of a well-known population to expand on results of their study. Our objective was to determine whether seasonal differences exist in the prevalence of endoparasites of Wisconsin sandhill cranes. We collected 7 to 10 fecal samples approximately every other week from a consistent roost site on the Wisconsin River (43°34\u2752.99\u27\u27N, 89°36\u2738.42\u27\u27W) near Briggsville, Wisconsin, from 29 May through 25 September 2008. The sample size was based on the assumption that endoparasite prevalence in this population was high: a single positive result would allow us to be 99% certain that the parasite was prevalent in 50% or greater of the crane population (Martin et al. 1987). Each anonymously collected fecal sample consisted of a single, fresh mass. Samples were collected into plastic bags and kept refrigerated until analysis (2-24 hours later). Three methods were used to detect parasites: a standard direct smear of feces in saline, fecal flotation in sodium nitrate solution (Ovatector, BGS Medical Products, Inc, Venice, FL.) (Greiner 1997), and examination of the uppermost layer of sediment 10 minutes following mixing of the sample with sodium nitrate
