Trainers, Shorten Thy Training! An experiment to predict the effectiveness of a high-quality, interactive electronic LC shelving tool

Training students to work in academic libraries is important work. It is also constant, given the nature of student turnover. Therefore, library managers and trainers should seek efficiencies in training without sacrificing quality. One part of training to examine for efficiencies is LC (Library of Congress) shelving training. This study examines which characteristics the best interactive electronic LC shelving games share per a literature review. Then it compares the performance of twenty shelvers who trained with a high-quality interactive electronic LC shelving training tool versus the performance of twenty shelvers who trained with an excellent static guide. The interactive electronic group scored higher on average and experienced fewer low scores on the LC shelving test. More significantly, the interactive group members pinpointed where they made errors, which suggests that library employees trained with interactive shelving tutorials would need less remediation than employees who were trained using static shelving guides.Master of Science in Library Scienc

Quantifying ecological variation across jurisdictional boundaries in a management mosaic landscape

Context Large landscapes exhibit natural heterogeneity. Land management can impose additional variation, altering ecosystem patterns. Habitat characteristics may reflect these management factors, potentially resulting in habitat differences that manifest along jurisdictional boundaries. Objectives We characterized the patchwork of habitats across a case study landscape, the Grand Canyon Protected Area-Centered Ecosystem. We asked: how do ecological conditions vary across different types of jurisdictional boundaries on public lands? We hypothesized that differences in fire and grazing, because they respond to differences in management over time, contribute to ecological differences by jurisdiction. Methods We collected plot-scale vegetation and soils data along boundaries between public lands units surrounding the Grand Canyon. We compared locations across boundaries of units managed differently, accounting for vegetation type and elevation differences that pre-date management unit designations. We used generalized mixed effects models to evaluate differences in disturbance and ecology across boundaries. Results Jurisdictions varied in evidence of grazing and fire. After accounting for these differences, some measured vegetation and soil properties also differed among jurisdictions. The greatest differences were between US Forest Service wilderness and Bureau of Land Management units. For most measured variables, US Forest Service non-wilderness units and National Park Service units were intermediate. Conclusions In this study, several ecological properties tracked jurisdictional boundaries, forming a predictable patchwork of habitats. These patterns likely reflect site differences that pre-date jurisdictions as well as those resulting from different management histories. Understanding how ecosystem differences manifest at jurisdictional boundaries can inform resource management, conservation, and cross-boundary collaborations

Estrategia para conservar las poblaciones de buitres del viejo mundo utilizando el enfoque de una salud

One Health brings the powerful interrelationship between human and wildlife health together with ecosystem health. The initial concept of One Health was formulated decades ago and focused on disease transfer from wildlife to human populations. More recently, the concept has been used to associate resilience to disease with the health of the ecosystem and resilience to environmental stressors. The need for a One Health approach is particularly evident in the plight of Old World vultures, which are facing a conservation crisis due to drastic reductions in populations across their entire range. Moreover, vulture conservation exemplifies many contemporary tenets of One Health; vultures are critical to a sustainable and resilient ecosystem, which in turn is essential for the socio-ecological health of human communities. In this review, we examine the complex factors contributing to the demise of Old World vulture populations, using the lens of One Health to conceptualize the primary drivers impacting the health and sustainability of these populations. The One Health concept provides the basis for the development of a framework that incorporates a multidimensional approach and includes human health, wildlife health, environmental and disease-related stressors, disease incidences, societal pressures, and environmental contaminants. Integrating societal needs with management aimed at maintaining healthy vulture populations is key for successfully using a One Health framework to optimize the health of human and wildlife populations and ensure ecosystem health.El enfoque ‘‘Una Salud’’ promueve una poderosa interrelacio´n entre la salud de los humanos y de la fauna salvaje asociados a la salud de los ecosistemas. El concepto inicial de Una Salud fue formulado de´cadas atra´s y se enfocaba en la transferencia de enfermedades de la fauna salvaje a las poblaciones humanas. Ma´s recientemente, el concepto ha sido usado para asociar la resiliencia a las enfermedades con la salud de los ecosistemas y la resiliencia a factores de estre´s ambiental. La necesidad de utilizar el enfoque de Una Salud es particularmente evidente ante la dif´ıcil situacio´n de los buitres del Viejo Mundo, los cuales se enfrentan a una situacio´n de crisis de conservacio´n debido a la reduccio´n dra´stica en sus poblaciones a lo largo de toda su a´rea de distribucio´n. Adema´s, la conservacio´n de los buitres ejemplifica mucho de los principios contempora´neos de Una Salud; los buitres son cr´ıticos para un ecosistema sostenible y resiliente, lo que a su vez es esencial para la salud socio-ecolo´gica de las comunidades humanas. En esta revisio´n, examinamos los factores complejos que contribuyen al descenso de las poblaciones de buitres del Viejo Mundo, usando el enfoque de Una Salud para conceptualizar los factores principales que impactan en la salud y la sostenibilidad de estas poblaciones. El concepto de Una Salud proporciona las bases para el desarrollo de un marco de referencia que incorpora un enfoque multidimensional, incluyendo la salud humana y de la vida silvestre, factores estresantes ambientales y de enfermedades, incidencia de enfermedades, presiones sociales y qu´ımicos ambientales. Integrar las necesidades de la sociedad con la gestio´n destinada a mantener poblaciones saludables de buitres es clave para usar exitosamente el marco de referencia de Una Salud y as´ı optimizar la salud de las poblaciones humanas y de la fauna salvaje asegurando la salud del ecosistema.The National Science Foundationhttps://bioone.org/journals/journal-of-raptor-researcham2022Zoology and Entomolog

Molecularly defined circuitry reveals input-output segregation in deep layers of the medial entorhinal cortex

SummaryDeep layers of the medial entorhinal cortex are considered to relay signals from the hippocampus to other brain structures, but pathways for routing of signals to and from the deep layers are not well established. Delineating these pathways is important for a circuit level understanding of spatial cognition and memory. We find that neurons in layers 5a and 5b have distinct molecular identities, defined by the transcription factors Etv1 and Ctip2, and divergent targets, with extensive intratelencephalic projections originating in layer 5a, but not 5b. This segregation of outputs is mirrored by the organization of glutamatergic input from stellate cells in layer 2 and from the hippocampus, with both preferentially targeting layer 5b over 5a. Our results suggest a molecular and anatomical organization of input-output computations in deep layers of the MEC, reveal precise translaminar microcircuitry, and identify molecularly defined pathways for spatial signals to influence computation in deep layers

How valid are current diagnostic criteria for dental erosion?

In principle, there is agreement about the clinical diagnostic criteria for dental erosion, basically defined as cupping and grooving of the occlusal/incisal surfaces, shallow defects on smooth surfaces located coronal from the enamel–cementum junction with an intact cervical enamel rim and restorations rising above the adjacent tooth surface. This lesion characteristic was established from clinical experience and from observations in a small group of subjects with known exposure to acids rather than from systematic research. Their prevalence is higher in risk groups for dental erosion compared to subjects not particularly exposed to acids, but analytical epidemiological studies on random or cluster samples often fail to find a relation between occurrence or severity of lesions and any aetiological factor. Besides other aspects, this finding might be due to lack of validity with respect to diagnostic criteria. In particular, cupping and grooving might be an effect of abrasion as well as of erosion and their value for the specific diagnosis of erosion must be doubted. Knowledge about the validity of current diagnostic criteria of different forms of tooth wear is incomplete, therefore further research is needed

Geographical and temporal distribution of SARS-CoV-2 clades in the WHO European Region, January to June 2020

We show the distribution of SARS-CoV-2 genetic clades over time and between countries and outline potential genomic surveillance objectives. We applied three available genomic nomenclature systems for SARS-CoV-2 to all sequence data from the WHO European Region available during the COVID-19 pandemic until 10 July 2020. We highlight the importance of real-time sequencing and data dissemination in a pandemic situation. We provide a comparison of the nomenclatures and lay a foundation for future European genomic surveillance of SARS-CoV-2.Peer reviewe

Evaluating the Effects of SARS-CoV-2 Spike Mutation D614G on Transmissibility and Pathogenicity.

Global dispersal and increasing frequency of the SARS-CoV-2 spike protein variant D614G are suggestive of a selective advantage but may also be due to a random founder effect. We investigate the hypothesis for positive selection of spike D614G in the United Kingdom using more than 25,000 whole genome SARS-CoV-2 sequences. Despite the availability of a large dataset, well represented by both spike 614 variants, not all approaches showed a conclusive signal of positive selection. Population genetic analysis indicates that 614G increases in frequency relative to 614D in a manner consistent with a selective advantage. We do not find any indication that patients infected with the spike 614G variant have higher COVID-19 mortality or clinical severity, but 614G is associated with higher viral load and younger age of patients. Significant differences in growth and size of 614G phylogenetic clusters indicate a need for continued study of this variant

Implementing Universal Supports at the Tier 4 Level

1) Our presentation will focus on the Tier One or Universal critical elements of PBIS and how we incorporate these elements into the GNETS setting. The presentation will review each of the TFI critical elements and provide the audience with the information and examples on how NM GNETS tailors the elements for a more restrictive setting. We combine evidence-based practices for student with severe behavior concerns and place them within the PBIS framework. We focus on how we incorporate social skill curricula into teaching the expectations, using a leveled system for our students, and combining many data sources with discipline data to best serve our students
