Universities Confront ‘Tech Disruption’: Perceptions of Student Engagement Online Using Two Learning Management Systems

This article is a teaching note on the experiences of students and professors as they adapted to the use of a new learning management system (LMS). Using pedagogical theories of student engagement and the online learning process, we explore how the design of an LMS affects student satisfaction and interaction with peers and the instructor. This descriptive, qualitative study reports student and instructor experiences in four hybrid sociology courses that used Google Classroom as an experimental LMS. These same students also used Blackboard, a more traditional LMS, in their other sociology classes, establishing a quasi within-subject point of comparison for these two systems. A survey (n=72) and four focus groups (n=54) were conducted among students to determine how student engagement is experienced differently on Classroom and Blackboard. Eighty-three percent of students reported feeling satisfied with Classroom over Blackboard. Focus groups revealed themes relating to usability and learnability; interaction and individuality; and facilitation of learning. Students and instructors responded more positively, with some exceptions, to Classroom’s reliability and interface, but claims about the transformative power of online tools are not wholly supported by student or instructor experiences. The study advances our understanding of how the LMS interface, design, and functionality play a role in student engagement online. Further research is needed to understand the full extent of Classroom’s impact on learning in the higher education landscape

Criminal Offending Among Respondents to Protective Orders: Crime Types and Patterns That Predict Victim Risk

Research has shown that respondents to protective orders have robust criminal histories and that criminal offending behavior often follows issuance of a protective order. Nonetheless, the specific nature of the association between protective orders and criminal offending remains unclear. This study uses two classes of statistical models to more clearly delineate that relationship. The models reveal factors and characteristics that appear to be associated with offending and protective order issuance and provide indications about when a victim is most at risk and when the justice system should be most ready to provide immediate protection

The Denial of Emergency Protection: Factors Associated with Court Decision Making

Despite the importance of civil orders of protection as a legal resource for victims of intimate partner violence, research is limited in this area, and most studies focus on the process following a court’s initial issuance of an emergency order. The purpose of this study is to address a major gap in the literature by examining cases where victims of intimate partner violence are denied access to temporary orders of protection. The study sample included a review of 2,205 petitions that had been denied by a Kentucky court during the 2003 fiscal year. The study offers important insights into the characteristics of petitioners and respondents to denied orders and outlines individual, contextual, structural, qualitative/perceptual, and procedural factors associated with the denial of temporary or emergency protective orders. Recommendations for statutory changes, judicial education, and future research to remedy barriers to protection are offered

Relationship and Injury Trends in the Homicide of Women Across the Lifespan: A Research Note

In 2006, more than 3,600 women in the United States lost their lives to homicide. Descriptive data regarding homicides of women are beginning to reveal important complexities regarding victim–offender relationships, severity of injury, and age of female homicide victim. More specifically, there is some indication that the correlation between victim–offender relationship and injury severity may be conditional, depending on victim age. This retrospective review accessed medical examiner records of female homicide victims from 2002 through 2004, and its findings offer additional illumination on the trends in associations of injury and relationship variables in the homicide of women over their life span. The study also examined the utility of the recently proposed Homicide Injury Scale (HIS) created by Safarik and Jarvis as a potential tool to explore these complicated associations by quantifying injury severity and examining its interrelationships with victim–offender relationship and age in cases of female homicide in Kentucky

Does habitat stability structure intraspecific genetic diversity? It’s complicated...

Regional phylogeographic studies have long been conducted in the southeastern United States for a variety of species. With some exceptions, many of these studies focus on single species or single clades of organisms, and those considering multiple species tend to focus on deep historical breaks causing differentiation. However, in many species more recent factors may be influencing genetic diversity. To understand the roles of historic and contemporary processes in structuring genetic diversity, we reanalyzed existing genetic data from Southeast of North America using approaches gleaned from phylogeographic and landscape genetic literature that were implemented across species including AMOVAs, PCoAs, Species Distribution Modelling, and tests of isolation by distance, environment, and habitat instability. Genetic variance was significantly partitioned by ecoregions, watersheds, and across phylogeographic breaks in the majority of species. Similarly, genetic variation was significantly associated with some combination of geographic or environmental distance or habitat instability in most species. Patterns of genetic variation were largely idiosyncratic across species. While habitat instability over time is significantly correlated with genetic diversity in some species, it appears generally less important than isolation by geographic or environmental distance. Our results suggest that many factors, both historical and contemporary, impact genetic diversity within a species, and more so, that these patterns aren’t always similar in closely related species. This supports the importance of species- specific factors and cautions against assumptions that closely related species will respond to historical and contemporary forces in similar ways

An inactivating caspase 11 passenger mutation originating from the 129 murine strain in mice targeted for c-IAP1

A recent study revealed that ES (embryonic stem) cell lines derived from the 129 murine strain carry an inactivating mutation within the caspase 11 gene (Casp4) locus [Kayagaki, Warming, Lamkanfi, Vande Walle, Louie, Dong, Newton, Qu, Liu, Heldens, Zhang, Lee, Roose-Girma and Dixit (2011) Nature 479, 117–121]. Thus, if 129 ES cells are used to target genes closely linked to caspase 11, the resulting mice might also carry the caspase 11 deficiency as a passenger mutation. In the present study, we examined the genetic loci of mice targeted for the closely linked c-IAP (cellular inhibitor of apoptosis) genes, which were generated in 129 ES cells, and found that, despite extensive backcrossing into a C57BL/6 background, c-IAP1−/− animals are also deficient in caspase 11. Consequently, data obtained from these mice should be re-evaluated in this new context

Activity-Based Funding of Hospitals and Its Impact on Mortality, Readmission, Discharge Destination, Severity of Illness, and Volume of Care: A Systematic Review and Meta-Analysis

Background: Activity-based funding (ABF) of hospitals is a policy intervention intended to re-shape incentives across health systems through the use of diagnosis-related groups. Many countries are adopting or actively promoting ABF. We assessed the effect of ABF on key measures potentially affecting patients and health care systems: mortality (acute and post-acute care); readmission rates; discharge rate to post-acute care following hospitalization; severity of illness; volume of care.     Methods: We undertook a systematic review and meta-analysis of the worldwide evidence produced since 1980. We included all studies reporting original quantitative data comparing the impact of ABF versus alternative funding systems in acute care settings, regardless of language. We searched 9 electronic databases (OVID MEDLINE, EMBASE, OVID Healthstar, CINAHL, Cochrane CENTRAL, Health Technology Assessment, NHS Economic Evaluation Database, Cochrane Database of Systematic Reviews, and Business Source), hand-searched reference lists, and consulted with experts. Paired reviewers independently screened for eligibility, abstracted data, and assessed study credibility according to a pre-defined scoring system, resolving conflicts by discussion or adjudication.     Results: Of 16,565 unique citations, 50 US studies and 15 studies from 9 other countries proved eligible (i.e. Australia, Austria, England, Germany, Israel, Italy, Scotland, Sweden, Switzerland). We found consistent and robust differences between ABF and no-ABF in discharge to post-acute care, showing a 24% increase with ABF (pooled relative risk = 1.24, 95% CI 1.18–1.31). Results also suggested a possible increase in readmission with ABF, and an apparent increase in severity of illness, perhaps reflecting differences in diagnostic coding. Although we found no consistent, systematic differences in mortality rates and volume of care, results varied widely across studies, some suggesting appreciable benefits from ABF, and others suggesting deleterious consequences.     Conclusions: Transitioning to ABF is associated with important policy- and clinically-relevant changes. Evidence suggests substantial increases in admissions to post-acute care following hospitalization, with implications for system capacity and equitable access to care. High variability in results of other outcomes leaves the impact in particular settings uncertain, and may not allow a jurisdiction to predict if ABF would be harmless. Decision-makers considering ABF should plan for likely increases in post-acute care admissions, and be aware of the large uncertainty around impacts on other critical outcomes

Safety and efficacy of fluoxetine on functional outcome after acute stroke (AFFINITY): a randomised, double-blind, placebo-controlled trial

Background Trials of fluoxetine for recovery after stroke report conflicting results. The Assessment oF FluoxetINe In sTroke recoverY (AFFINITY) trial aimed to show if daily oral fluoxetine for 6 months after stroke improves functional outcome in an ethnically diverse population. Methods AFFINITY was a randomised, parallel-group, double-blind, placebo-controlled trial done in 43 hospital stroke units in Australia (n=29), New Zealand (four), and Vietnam (ten). Eligible patients were adults (aged ≥18 years) with a clinical diagnosis of acute stroke in the previous 2–15 days, brain imaging consistent with ischaemic or haemorrhagic stroke, and a persisting neurological deficit that produced a modified Rankin Scale (mRS) score of 1 or more. Patients were randomly assigned 1:1 via a web-based system using a minimisation algorithm to once daily, oral fluoxetine 20 mg capsules or matching placebo for 6 months. Patients, carers, investigators, and outcome assessors were masked to the treatment allocation. The primary outcome was functional status, measured by the mRS, at 6 months. The primary analysis was an ordinal logistic regression of the mRS at 6 months, adjusted for minimisation variables. Primary and safety analyses were done according to the patient's treatment allocation. The trial is registered with the Australian New Zealand Clinical Trials Registry, ACTRN12611000774921. Findings Between Jan 11, 2013, and June 30, 2019, 1280 patients were recruited in Australia (n=532), New Zealand (n=42), and Vietnam (n=706), of whom 642 were randomly assigned to fluoxetine and 638 were randomly assigned to placebo. Mean duration of trial treatment was 167 days (SD 48·1). At 6 months, mRS data were available in 624 (97%) patients in the fluoxetine group and 632 (99%) in the placebo group. The distribution of mRS categories was similar in the fluoxetine and placebo groups (adjusted common odds ratio 0·94, 95% CI 0·76–1·15; p=0·53). Compared with patients in the placebo group, patients in the fluoxetine group had more falls (20 [3%] vs seven [1%]; p=0·018), bone fractures (19 [3%] vs six [1%]; p=0·014), and epileptic seizures (ten [2%] vs two [<1%]; p=0·038) at 6 months. Interpretation Oral fluoxetine 20 mg daily for 6 months after acute stroke did not improve functional outcome and increased the risk of falls, bone fractures, and epileptic seizures. These results do not support the use of fluoxetine to improve functional outcome after stroke
