    ADVOCATE: A Legislative Advocacy Model for Counseling Students

    Get PDF
    In the classroom, master’s students learn that advocacy is a central component of the counseling profession and counselor identity, whereas doctoral students train to be advocacy leaders. While counselor educators often infuse advocacy into the classroom through assignments and use current advocacy models present in the literature, we found a need for a practical model specifically for legislative advocacy to implement with counseling graduate students outside of the classroom. The authors pulled from their collective experience of meeting with state legislators at the state Capitol to create the ADVOCATE Model, a practical, step-by-step guide to legislative advocacy. The authors share the details of their model and discuss implications and recommendations for counselor educators and students

    Human respiratory syncytial virus (hRSV) and human metapneumovirus (hMPV) are major causes of illness among children, the elderly, and the immunocompromised. No vaccine has been licensed for protection against either of these viruses. We tested the ability of two Venezuelan equine encephalitis virus-based viral replicon particle (VEE-VRP) vaccines that express the hRSV or hMPV fusion (F) protein to confer protection against hRSV or hMPV in African green monkeys. Animals immunized with VEE-VRP vaccines developed RSV or MPV F-specific antibodies and serum neutralizing activity. Compared to control animals, immunized animals were better able to control viral load in the respiratory mucosa following challenge and had lower levels of viral genome in nasopharyngeal and bronchoalveolar lavage fluids. The high level of immunogenicity and protective efficacy induced by these vaccine candidates in nonhuman primates suggest that they hold promise for further development

    Oxygen Abundances in Metal-Poor Stars

    We present oxygen abundances derived from both the permitted and forbidden oxygen lines for 55 subgiants and giants with [Fe/H] values between -2.7 and solar with the goal of understanding the discrepancy in the derived abundances. A first attempt, using \teff{} values from photometric calibrations and surface gravities from luminosities, obtained agreement between the indicators for turn-off stars, but the disagreement was large for evolved stars. We find that the difference in the oxygen abundances derived from the permitted and forbidden lines is most strongly affected by \teff{}, and we derive a new \teff{} scale based on forcing the two sets of lines to give the same oxygen abundances. These new parameters, however, do not agree with other observables, such as theoretical isochrones or Balmer-line profile based \teff{} determinations. Our analysis finds that one-dimensional, LTE analyses (with published NLTE corrections for the permitted lines) cannot fully resolve the disagreement in the two indicators without adopting a temperature scale incompatible with other temperature indicators. We also find no evidence of circumstellar emission in the forbidden lines, removing such emission as a possible cause for the discrepancy.Comment: 41 pages, 12 tables, 17 figures.

    Genetics of randomly bred cats support the cradle of cat domestication being in the Near East

    Get PDF
    Cat domestication likely initiated as a symbiotic relationship between wildcats (Felis silvestris subspecies) and the peoples of developing agrarian societies in the Fertile Crescent. As humans transitioned from hunter-gatherers to farmers ~12,000 years ago, bold wildcats likely capitalized on increased prey density (i.e., rodents). Humans benefited from the cats’ predation on these vermin. To refine the site(s) of cat domestication, over 1000 random-bred cats of primarily Eurasian descent were genotyped for single-nucleotide variants and short tandem repeats. The overall cat population structure suggested a single worldwide population with significant isolation by the distance of peripheral subpopulations. The cat population heterozygosity decreased as genetic distance from the proposed cat progenitor’s (F.s. lybica) natural habitat increased. Domestic cat origins are focused in the eastern Mediterranean Basin, spreading to nearby islands, and southernly via the Levantine coast into the Nile Valley. Cat population diversity supports the migration patterns of humans and other symbiotic species

    The Consensus Coding Sequence (Ccds) Project: Identifying a Common Protein-Coding Gene Set for the Human and Mouse Genomes

    Get PDF
    Effective use of the human and mouse genomes requires reliable identification of genes and their products. Although multiple public resources provide annotation, different methods are used that can result in similar but not identical representation of genes, transcripts, and proteins. The collaborative consensus coding sequence (CCDS) project tracks identical protein annotations on the reference mouse and human genomes with a stable identifier (CCDS ID), and ensures that they are consistently represented on the NCBI, Ensembl, and UCSC Genome Browsers. Importantly, the project coordinates on manually reviewing inconsistent protein annotations between sites, as well as annotations for which new evidence suggests a revision is needed, to progressively converge on a complete protein-coding set for the human and mouse reference genomes, while maintaining a high standard of reliability and biological accuracy. To date, the project has identified 20,159 human and 17,707 mouse consensus coding regions from 17,052 human and 16,893 mouse genes. Three evaluation methods indicate that the entries in the CCDS set are highly likely to represent real proteins, more so than annotations from contributing groups not included in CCDS. The CCDS database thus centralizes the function of identifying well-supported, identically-annotated, protein-coding regions.National Human Genome Research Institute (U.S.) (Grant number 1U54HG004555-01)Wellcome Trust (London, England) (Grant number WT062023)Wellcome Trust (London, England) (Grant number WT077198

    The Astropy Problem

    Get PDF
    The Astropy Project (http://astropy.org) is, in its own words, "a community effort to develop a single core package for Astronomy in Python and foster interoperability between Python astronomy packages." For five years this project has been managed, written, and operated as a grassroots, self-organized, almost entirely volunteer effort while the software is used by the majority of the astronomical community. Despite this, the project has always been and remains to this day effectively unfunded. Further, contributors receive little or no formal recognition for creating and supporting what is now critical software. This paper explores the problem in detail, outlines possible solutions to correct this, and presents a few suggestions on how to address the sustainability of general purpose astronomical software

    The Fourteenth Data Release of the Sloan Digital Sky Survey: First Spectroscopic Data from the extended Baryon Oscillation Spectroscopic Survey and from the second phase of the Apache Point Observatory Galactic Evolution Experiment

    Get PDF
    The fourth generation of the Sloan Digital Sky Survey (SDSS-IV) has been in operation since July 2014. This paper describes the second data release from this phase, and the fourteenth from SDSS overall (making this, Data Release Fourteen or DR14). This release makes public data taken by SDSS-IV in its first two years of operation (July 2014-2016). Like all previous SDSS releases, DR14 is cumulative, including the most recent reductions and calibrations of all data taken by SDSS since the first phase began operations in 2000. New in DR14 is the first public release of data from the extended Baryon Oscillation Spectroscopic Survey (eBOSS); the first data from the second phase of the Apache Point Observatory (APO) Galactic Evolution Experiment (APOGEE-2), including stellar parameter estimates from an innovative data driven machine learning algorithm known as "The Cannon"; and almost twice as many data cubes from the Mapping Nearby Galaxies at APO (MaNGA) survey as were in the previous release (N = 2812 in total). This paper describes the location and format of the publicly available data from SDSS-IV surveys. We provide references to the important technical papers describing how these data have been taken (both targeting and observation details) and processed for scientific use. The SDSS website (www.sdss.org) has been updated for this release, and provides links to data downloads, as well as tutorials and examples of data use. SDSS-IV is planning to continue to collect astronomical data until 2020, and will be followed by SDSS-V.Comment: SDSS-IV collaboration alphabetical author data release paper.

    Deletion of the Chd6 exon 12 affects motor coordination

    Get PDF
    Members of the CHD protein family play key roles in gene regulation through ATP-dependent chromatin remodeling. This is facilitated by chromodomains that bind histone tails, and by the SWI2/SNF2-like ATPase/helicase domain that remodels chromatin by moving histones. Chd6 is ubiquitously expressed in both mouse and human, with the highest levels of expression in the brain. The Chd6 gene contains 37 exons, of which exons 12-19 encode the highly conserved ATPase domain. To determine the biological role of Chd6, we generated mouse lines with a deletion of exon 12. Chd6 without exon 12 is expressed at normal levels in mice, and Chd6 Exon 12 −/− mice are viable, fertile, and exhibit no obvious morphological or pathological phenotype. Chd6 Exon 12 −/− mice lack coordination as revealed by sensorimotor analysis. Further behavioral testing revealed that the coordination impairment was not due to muscle weakness or bradykinesia. Histological analysis of brain morphology revealed no differences between Chd6 Exon 12 −/− mice and wild-type (WT) controls. The location of CHD6 on human chromosome 20q12 is overlapped by the linkage map regions of several human ataxias, including autosomal recessive infantile cerebellar ataxia (SCAR6), a nonprogressive cerebrospinal ataxia. The genomic location, expression pattern, and ataxic phenotype of Chd6 Exon 12 −/− mice indicate that mutations within CHD6 may be responsible for one of these ataxias
