Pitfall Trap Collections of Ground Beetle Larvae (Coleoptera: Carabidae) in Kentucky Alfalfa Fields

Pitfall traps were installed in alfalfa fields to monitor the seasonality and abundance of immature ground beetles. Head capsule widths were determined by instar for Evarthrus sodalis, Harpalus pennsylvanicus, Chlaenius tricolor, Scarites subterraneus, Amara cupreolata, and A. impuncticollis. Seasonality of larval and adult catches indicated that E. sodalis, H. pennsylvanicus and A. impuncticollis overwinter in a larval diapause while A. cupreolata and S. subterraneus overwinter in the adult stage

Relax, Don\u27t [be] Anxious: RDA at the Ball State University Libraries (Muncie, IN)

Provides an overview of how librarians in the Cataloging and Metadata Services (CAMS) department at the Ball State University Libraries (Muncie, IN) prepared for and implemented cataloging in RDA. Also covers the presenter’s training and evaluation of copy catalogers using RDA for monographic cataloging (books, ebooks, video recordings, maps) and the writing of local procedures

Behavioral Health Practice Competencies Among Graduate Social Work Students: A Program Evaluation

The Health Services and Resource Administration (HRSA) of the Department of Health and Human Services (DHHS) has recognized a need for mental health and substance abuse services for children, adolescents, and transitional youth who are at-risk for developing behavioral health disorders. In response to this need, the Obama administration delegated funds to multiple universities for the purpose of expanding the social work labor force. Louisiana State University is among those that received a block grant, allowing some of the students in the School of Social Work to participate in a Behavioral Health Workforce Education Training (BHWET) Program. This quasi-experimental study explored whether syudents’ participation in the BHWET program increased their competencies in five important areas of social work: values, ethics, and theoretical perspectives; assessment; intervention; at-risk youth services, programs, and policies; and leadership. Comparisons of surveys indicated that students who participated in the BHWET program were significantly more competent than their peers who did not participate in the BHWET program in all of the five areas analyzed. We discuss the limitations of this study as well as implications for future social work practice and research

Mapping land cover from satellite images: A basic, low cost approach

Simple, inexpensive methodologies developed for mapping general land cover and land use categories from LANDSAT images are reported. One methodology, a stepwise, interpretive, direct tracing technique was developed through working with university students from different disciplines with no previous experience in satellite image interpretation. The technique results in maps that are very accurate in relation to actual land cover and relative to the small investment in skill, time, and money needed to produce the products

Interleukin 2 activation of natural killer cells rapidly induces the expression and phosphorylation of the Leu-23 activation antigen.

IL-2 potentiates both growth and cytotoxic function of T lymphocytes and NK cells. Resting peripheral blood NK cells can respond directly to rIL-2, without requirement for accessory cells or cofactors, and enhanced cytotoxicity can be measured within a few hours after exposure to this lymphokine. In this study, we describe an activation antigen, Leu-23, that is rapidly induced and phosphorylated after IL-2 stimulation of NK cells and a subset of low buoyant density T lymphocytes. Previously, it has been uncertain whether all NK cells or only a subset are responsive to IL-2. Since within 18 h after exposure to IL-2, essentially all NK cells express Leu-23, these findings indicate that all peripheral blood NK cells are responsive to stimulation by IL-2. The Leu-23 antigen is a disulfide-bonded homodimer, composed of 24-kD protein subunits with two N-linked oligosaccharides. Appearance of this glycoprotein on NK cells is IL-2 dependent and closely parallels IL-2-induced cytotoxicity against NK-resistant solid tumor cell targets

A Classroom Experiment: Using Shared Shelf to Archive and Share Student Video Film Reviews

The Hope College Library, as a participant in the CIC Consortium on Digital Resources for Teaching and Research, sought to extend the usage of Shared Shelf beyond a repository for local archival and art collections to a platform for faculty and student scholarship and creative output. Working with Dr. Lauren Janes (Assistant Professor of History), Tori Longfield (Digital Liberal Arts Librarian) proposed testing Shared Shelf for student use in the final course project for HIST 280: Modern Imperialism (Spring 2017). In collaboration with Jeremy Barney (Metadata and Digital Collections Librarian), a workflow was established to facilitate communication between the library and Dr. Janes, generate a project space for students within Shared Shelf, and instruct students on using the system. Partnering with faculty on these types of course projects affords the Hope College Library with the opportunity to highlight Shared Shelf as a useful platform for sharing student work and introduce students to digital asset management systems and the importance of archiving and describing digital assets (metadata)

Data assimilation for the Martian atmosphere using MGS Thermal Emission Spectrometer observations

From the introduction: Given the quantity of data expected from current and forthcoming spacecraft missions to Mars, it is now possible to use data assimilation as a means of atmospheric analysis for the first time for a planet other than the Earth. Several groups have described plans to develop assimilation schemes for Mars [Banfield et al., 1995; Houben, 1999; Lewis and Read, 1995; Lewis et al., 1996, 1997; Zhang et al., 2001]. Data assimilation is a technique for the analysis of atmospheric observations which combines currently valid information with prior knowledge from previous observations and dynamical and physical constraints, via the use of a numerical model. Despite the number of new missions, observations of the atmosphere of Mars in the near future are still likely to be sparse when compared to those of the Earth, perhaps comprising one orbiter and a few surface stations at best at any one time. Data assimilation is useful as a means to extract the maximum information from such observations, both by a form of interpolation in space and time using model constraints and by the combination of information from different observations, e.g. temperature profiles and surface pressure measurements which may be irregularly distributed. The procedure can produce a dynamically consistent set of meteorological fields and can be used directly to test and to refine an atmospheric model against observations

Assimilation of TES data from the Mars Global Surveyor scientifc mapping phase

The Thermal Emission Spectrometer (TES)aboard Mars Global Surveyor has produced data which cover almost two Martian years so far (during its scientific mapping phase). Thermal profiles for the atmosphere below 40 km and total dust opacities can be retrieved from TES nadir spectra and assimilated into a Mars general circulation model (MGCM), by using the assimilation techniques described in detail by Lewis et al. (2002). This paper describes some preliminary results from assimilations of temperature data from the period Ls=141°- 270° corresponding to late northern summer until winter solstice on Mars. Work in progress is devoted to assimilate both temperature and total dust opacity data for the full period for which they are already available

Clogging by sieving in microchannels: Application to the detection of contaminants in colloidal suspensions

We report on a microfluidic method that allows measurement of a small concentration of large contaminants in suspensions of solid micrometer-scale particles. To perform the measurement, we flow the colloidal suspension through a series of constrictions, i.e. a microchannel of varying cross-section. We show and quantify the role of large contaminants in the formation of clogs at a constriction and the growth of the resulting filter cake. By measuring the time interval between two clogging events in an array of parallel microchannels, we are able to estimate the concentration of contaminants whose size is selected by the geometry of the microfluidic device. This technique for characterizing colloidal suspensions offers a versatile and rapid tool to explore the role of contaminants on the properties of the suspensions
