Admission Criteria as Predictors of Student Success

Objective: Evaluate impact of various admission criteria elements (cognitive, behavioral) as predictors of first-term college GPA and on-time graduation. Methods & Results: Predictive models were developed to examine if the current admission criteria: high school GPA (HSGPA), ACT Composite score, interview score, etc are significant predictors for student success defined as first-term college GPA, on-time graduation among PharmD students at a direct entry private university. The study sample consisted of 395 pharmacy students matriculated as first-time freshmen students during fall 2007 through fall 2009. Results from the hierarchical linear regression analysis indicated that both HSGPA and ACT Composite score were significant predictors for first-term college GPA. After taking into account relevant demographic factors, the final model explained 22% of the total variance in first-term college GPA, with HSGPA accounting for 18% of the total variance and ACT Composite score accounting for only 3%. For predicting on-time graduation using the logistic regression method, HSGPA alone was the significant predictor while the model had no substantial impact on predicting on-time graduation (4% of the total variance). Further study is needed to develop a more comprehensive model involving behavioral or psychosocial factors impacting student success outcomes. Implications: This data was used to adjust relative weight of HSGPA and standardized tests scores in the application evaluation rubric. It is also being used to allocate student services resources for student retention initiatives

Pharmacists’ Provision of Contraception: Established and Emerging Roles

Pharmacists’ roles in provision of family planning products is expanding in the United States (U.S.). This article details established as well as emerging roles for U.S. pharmacists in the provision of contraception. These include helping patients develop reproductive life plans; dispensing prescription contraceptive products and counseling patients; assisting and educating patients with non-prescription contraceptive products, including emergency contraception; participating in collaborative practice agreements; administering contraception products; and making referrals and developing partnerships. The provision of contraception in the U.S. is dynamic, and pharmacists should continue to be aware of changes that will impact them professionally. As approximately 45% of pregnancies in the U.S. are unintended, through these roles pharmacists can impact an important public health priority.

Gene content evolution in the arthropods

Arthropods comprise the largest and most diverse phylum on Earth and play vital roles in nearly every ecosystem. Their diversity stems in part from variations on a conserved body plan, resulting from and recorded in adaptive changes in the genome. Dissection of the genomic record of sequence change enables broad questions regarding genome evolution to be addressed, even across hyper-diverse taxa within arthropods. Using 76 whole genome sequences representing 21 orders spanning more than 500 million years of arthropod evolution, we document changes in gene and protein domain content and provide temporal and phylogenetic context for interpreting these innovations. We identify many novel gene families that arose early in the evolution of arthropods and during the diversification of insects into modern orders. We reveal unexpected variation in patterns of DNA methylation across arthropods and examples of gene family and protein domain evolution coincident with the appearance of notable phenotypic and physiological adaptations such as flight, metamorphosis, sociality, and chemoperception. These analyses demonstrate how large-scale comparative genomics can provide broad new insights into the genotype to phenotype map and generate testable hypotheses about the evolution of animal diversity

BitView : using blockchain technology to validate and diffuse global usage data for academic publications

We suggest that blockchain technology could be used to underpin a validated, reliable, and transparent usage metric for research outputs. Previous attempts to create online usage metrics have been unsuccessful largely because it has been difficult to co-ordinate agreement between all parties on the rules of data collection and the distribution of the workload of data synthesis and dissemination. Blockchain technology can be utilized to bypass this co-ordination problem. We propose the creation of a bibliometric blockchain (called BitView) which forms a decentralized ledger of the online usage of scholarly research outputs. By means of a worked example, we demonstrate how this blockchain could ensure that all parties adhere to the same rules of data collection, and that the workload of data synthesis is distributed equitably. Moreover, we outline how public-private key cryptography could ensure that users’ data remains private while librarians, academics, publishers, and research funders retain open access to all the data they require. It is concluded that a usage metric underpinned by blockchain technology may lead to a richer and healthier ecosystem in which publishers and academics are incentivized to widen access to their research.Postprin

Effects of antiplatelet therapy on stroke risk by brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases: subgroup analyses of the RESTART randomised, open-label trial

Background Findings from the RESTART trial suggest that starting antiplatelet therapy might reduce the risk of recurrent symptomatic intracerebral haemorrhage compared with avoiding antiplatelet therapy. Brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases (such as cerebral microbleeds) are associated with greater risks of recurrent intracerebral haemorrhage. We did subgroup analyses of the RESTART trial to explore whether these brain imaging features modify the effects of antiplatelet therapy

Do Author-Suggested Reviewers Rate Submissions More Favorably than Editor-Suggested Reviewers? A Study on Atmospheric Chemistry and Physics

Background: Ratings in journal peer review can be affected by sources of bias. The bias variable investigated here was the information on whether authors had suggested a possible reviewer for their manuscript, and whether the editor had taken up that suggestion or had chosen a reviewer that had not been suggested by the authors. Studies have shown that authorsuggested reviewers rate manuscripts more favorably than editor-suggested reviewers do. Methodology/Principal Findings: Reviewers ’ ratings on three evaluation criteria and the reviewers ’ final publication recommendations were available for 552 manuscripts (in total 1145 reviews) that were submitted to Atmospheric Chemistry and Physics, an interactive open access journal using public peer review (authors ’ and reviewers ’ comments are publicly exchanged). Public peer review is supposed to bring a new openness to the reviewing process that will enhance its objectivity. In the statistical analysis the quality of a manuscript was controlled for to prevent favorable reviewers ’ ratings from being attributable to quality instead of to the bias variable. Conclusions/Significance: Our results agree with those from other studies that editor-suggested reviewers rated manuscripts between 30 % and 42 % less favorably than author-suggested reviewers. Against this backdrop journal editors should consider either doing without the use of author-suggested reviewers or, if they are used, bringing in more than one editor-suggested reviewer for the review process (so that the review by author-suggested reviewers can be put i

Speciation in little: the role of range and body size in the diversification of Malagasy mantellid frogs

<p>Abstract</p> <p>Background</p> <p>The rate and mode of lineage diversification might be shaped by clade-specific traits. In Madagascar, many groups of organisms are characterized by tiny distribution ranges and small body sizes, and this high degree of microendemism and miniaturization parallels a high species diversity in some of these groups. We here investigate the geographic patterns characterizing the radiation of the frog family Mantellidae that is virtually endemic to Madagascar. We integrate a newly reconstructed near-complete species-level timetree of the Mantellidae with georeferenced distribution records and maximum male body size data to infer the influence of these life-history traits on each other and on mantellid diversification.</p> <p>Results</p> <p>We reconstructed a molecular phylogeny based on nuclear and mitochondrial DNA for 257 species and candidate species of the mantellid frog radiation. Based on this phylogeny we identified 53 well-supported pairs of sister species that we used for phylogenetic comparative analyses, along with whole tree-based phylogenetic comparative methods. Sister species within the Mantellidae diverged at 0.2-14.4 million years ago and more recently diverged sister species had geographical range centroids more proximate to each other, independently of their current sympatric or allopatric occurrence. The largest number of sister species pairs had non-overlapping ranges, but several examples of young microendemic sister species occurring in full sympatry suggest the possibility of non-allopatric speciation. Range sizes of species included in the sister species comparisons increased with evolutionary age, as did range size differences between sister species, which rejects peripatric speciation. For the majority of mantellid sister species and the whole mantellid radiation, range and body sizes were associated with each other and small body sizes were linked to higher mitochondrial nucleotide substitution rates and higher clade diversity. In contrast, small range sizes were unexpectedly associated with a slow-down of mitochondrial substitution rates.</p> <p>Conclusions</p> <p>Based on these results we define a testable hypothesis under which small body sizes result in limited dispersal capabilities and low physiological tolerances, causing smaller and more strongly fragmented ranges. This can be thought to facilitate reproductive isolation and thus favor speciation. Contrary to the expectation of the faster speciation of such microendemic phenotype species, we only found small body sizes of mantellid frogs to be linked to higher diversification and substitution rates, but not small range sizes. A joint analysis of various species-rich regional anuran radiations might provide enough species with all combinations of range and body sizes for a more conclusive test of this hypothesis.</p
