Biology Student Perceptions of Information Literacy Instruction in the Context of an Essential Skills Workshop Series
The University Libraries at the University of New Mexico reconfigured their established library instruction program for biology as part of a broader grant-funded essential skills workshop series for STEM students. This initiative standardized supplementary instruction through seven in-person and online workshops delivered to students through the Biology Department’s four core undergraduate laboratory courses. Post-workshop feedback data were gathered from students throughout the two-year grant period. The present study analyzes this data set—including 3,797 completed student surveys from both library and non-library workshops over the course of four semesters—with the goal of understanding STEM student perceptions of the value of information literacy skills as compared to the general and disciplinary value of other essential intellectual and practical skills. The findings suggest that undergraduate biology students generally perceive information literacy to be among the most valuable and relevant skills introduced through the workshop series. The results have the potential to inform information literacy instruction practices and collaborative efforts with broader essential skills education programs
The Home Environment And Its Impact on Literacy Development
Due to the understanding that literacy development is based on an individuals discourse, and is acquired through social interactions with others it is essential to look at literacy acquisition through the perspective of the home environment. How does a child’s home environment impact the development of a child’s literacy acquisition? By studying the home life of five student participants and five parent participants, it became clear that parents are the greatest influence on a child’s ability to read and write. Inevitably, there is a continued link between home and school and teachers must take this knowledge and help support parents by teaching parents the skills they need to help their children
Impact of Yoga on Low Back Pain and Function: A Systematic Review and Meta-Analysis
An estimated 70% of people will experience low back pain at some point in their lives, and recurrence rates can be as high as 85%. Recent studies suggest that yoga – a widely practiced physical/mental discipline – may relieve back pain and reduce functional disability. The objective of this study was to conduct a systematic review and meta-analysis of the existing research on the effects of yoga on chronic low back pain and function. Our literature search began April 2011 and continued through October 2011. Cochrane, PubMed, CINAHL, Embase, ProQuest Dissertations and Theses, Google Scholar, and Clinicaltrials.gov databases were searched electronically. The search terms used were: yoga AND back pain. A total of 58 relevant studies were originally identified through the database searches. Of those, 45 were excluded on the basis of the title and/or review of the abstract. The 13 remaining studies were fully evaluated via a careful review of the full text. On the basis of the inclusion and exclusion criteria, 6 studies were excluded, leaving a total of 7 studies to be included in the meta-analyses of the impact of yoga on low back pain and function. Effect sizes were calculated as the standardized mean difference and meta-analyses were completed using a random-effects model. Overall, yoga was found to result in a medium, beneficial effect on chronic low back pain [overall effect size (ES) = 0.58, p\u3c0.001], indicating that subjects practicing yoga reported significantly less pain than control subjects. Yoga subjects also reported significantly less functional disability after the intervention (overall ES = 0.53, p\u3c0.001). Moreover, the improvements in pain and function for yoga subjects remained statistically significant 12-24 weeks after the end of the intervention (overall ES = 0.44-0.54, p≤0.002). In conclusion, yoga practice can significantly reduce pain and increase functional ability in chronic low back pain patients
Robust Analysis of Metabolic Pathways
Flux Balance Analysis (FBA) is a widely used computational model for studying the metabolic pathways of cells and the role individual metabolites and reactions play in maintaining cell function. However, the successes of FBA have been limited by faulty biological assumptions and computational imperfections. We introduce Robust Analysis of Metabolic Pathways (RAMP) to provide a more theoretically sound and computationally accurate model of cellular metabolism. RAMP overcomes the faulty assumptions of traditional FBA by allowing deviation from steady-state and accounting for variability across a cellular culture. Computationally, RAMP more successfully predicts the lethality of gene knockouts and reduces degeneracy in optimal ux values. Analytical results establish the stability of RAMP under perturbations in modeling parameters. The inclusion of new modeling parameters in RAMP opens the possibility of modeling different cellular cultures in a wider range of conditions, including non- optimized cultures. We conclude that RAMP is an improvement over traditional FBA and deserves further study
Where to Next for Optimizing Adherence in Large-scale Trials of CPAP?
Large-scale randomized trials of positive airway pressure (PAP) efficacy have been largely negative yet PAP adherence was notably sub-optimal across the trials. To address this limitation, evidence-based PAP adherence protocols embedded within the larger trial protocol are recommended. The complexity of such protocols will be dependent on adequacy of resources, including funding and inclusion of behavioral scientist experts on the scientific team, and trial-specific considerations (e.g., target population) and methods. Recommendations for optimizing PAP adherence in large-scale trials are set forth that address rigor and reproducibility
The Effectiveness of an App-Based Nurse-Moderated Program for New Mothers With Depression and Parenting Problems (eMums Plus):Pragmatic Randomized Controlled Trial
Background: Postnatal depression and caregiving difficulties adversely affect mothers, infants, and later childhood development. In many countries, resources to help mothers and infants are limited. Online group-based nurse-led interventions have the potential to help address this problem by providing large numbers of mothers with access to professional and peer support during the postnatal period. Objective: This study tested the effectiveness of a 4-month online group-based nurse-led intervention delivered when infants were aged 2 to 6 months as compared with standard care outcomes. Methods: The study was a block randomized control trial. Mothers were recruited at the time they were contacted for the postnatal health check offered to all mothers in South Australia. Those who agreed to participate were randomly assigned to the intervention or standard care. The overall response rate was 63.3% (133/210). Primary outcomes were the level of maternal depressive symptoms assessed with the Edinburgh Postnatal Depression Scale (EPDS) and quality of maternal caregiving assessed using the Parenting Stress Index (PSI; competence and attachment subscales), the Parenting Sense of Competence Scale (PSCS), and the Nursing Child Assessment Satellite Training Scale. Assessments were completed at baseline (mean child age 4.9 weeks [SD 1.4]) and again when infants were aged 8 and 12 months. Results: Outcomes were evaluated using linear generalized estimating equations adjusting for postrandomization group differences in demographic characteristics and the outcome score at baseline. There were no significant differences in the intervention and standard care groups in scores on the PSI competence subscale (P=.69) nor in the PSCS (P=.11). Although the group by time interaction suggested there were differences over time between the EPDS and PSI attachment subscale scores in the intervention and standard care groups (P=.001 and P=.04, respectively), these arose largely because the intervention group had stable scores over time whereas the standard care group showed some improvements between baseline and 12 months. Mothers engaged well with the intervention with at least 60% (43/72) of mothers logging-in once per week during the first 11 weeks of the intervention. The majority of mothers also rated the intervention as helpful and user-friendly. Conclusions: Mothers reported that the intervention was helpful, and the app was described as easy to use. As such, it appears that support for mothers during the postnatal period, provided using mobile phone technology, has the potential to be an important addition to existing services. Possible explanations for the lack of differences in outcomes for the 2 groups in this study are the failure of many mothers to use key components of the intervention and residual differences between the intervention and standard care groups post randomization.Alyssa Sawyer, Amy Kaim, Huynh-Nhu Le, Denise McDonald, Murthy Mittinty, John Lynch, Michael Sawye
Insights into volcanic hazards and plume chemistry from multi-parameter observations: the eruptions of Fimmvörðuháls and Eyjafjallajökull (2010) and Holuhraun (2014–2015)
The eruptions of Eyjafjallajökull volcano in 2010 (including its initial effusive phase at Fimmvörðuháls and its later explosive phase from the central volcano) and Bárðarbunga volcano in 2014–2015 (at Holuhraun) were widely reported. Here, we report on complementary, interdisciplinary observations made of the eruptive gases and lavas that shed light on the processes and atmospheric impacts of the eruptions, and afford an intercomparison of contrasting eruptive styles and hazards. We find that (i) consistent with other authors, there are substantial differences in the gas composition between the eruptions; namely that the deeper stored Eyjafjallajökull magmas led to greater enrichment in Cl relative to S; (ii) lava field SO2 degassing was measured to be 5–20% of the total emissions during Holuhraun, and the lava emissions were enriched in Cl at both fissure eruptions—particularly Fimmvörðuháls; and (iii) BrO is produced in Icelandic plumes in spite of the low UV levels
Dealing with alcohol-related harm and the night-time economy
Alcohol-related problems are a major cause of social disorder and illness in Australia. In particular, problems associated with the night-time economies of urban and regional centres cause substantial community concern and are a considerable drain on police, community and health resources. The estimated cost of alcohol to the community is $15.3 billion, including costs associated with crime, violence, patient treatment, loss of productivity and premature deaths in 2004–05 (Collins 2008). Alcohol has also been identified as a factor in around three quarters of assaults and incidents of offensive behaviour on the street (Buss 1995). Previous research has identified several issues that contribute to the levels of short-term harm associated with risky drinking. These include: excessive consumption at licensed premises, consumption in public areas and lack of transport and security in entertainment precincts (Homel et al. 1992; Graham & Homel 2008).Drinking in licensed venues is another predictor of harm and public disorder. More than half of offences occurring on the street have been associated with licensed premises in Australia (Buss 1995). A complex range of factors increase risky drinking and associated harms on licensed premises including: aspects of patron mix; levels of comfort, boredom, and intoxication; promotions that cause mass intoxication; and the behaviour of security/bouncers (Homel et al. 1992). Violence has also been shown to be perpetuated by poor venue management, lax police surveillance, lack of transport options for patrons, and inappropriate bureaucratic controls and legislation (Homel et al. 1992). This project aims to provide evidence-based knowledge regarding the implementation and impact of innovative local initiatives directed at alcohol-related harms.<br /
Implementing Electronic Tablet-Based Education of Acute Care Patients
Poor education-related discharge preparedness for patients with heart failure is believed to be a major cause of avoidable rehospitalizations. Technology-based applications offer innovative educational approaches that may improve educational readiness for patients in both inpatient and outpatient settings; however, a number of challenges exist when implementing electronic devices in the clinical setting. Implementation challenges include processes for "on-boarding" staff, mediating risks of cross-contamination with patients' device use, and selling the value to staff and health system leaders to secure the investment in software, hardware, and system support infrastructure. Strategies to address these challenges are poorly described in the literature. The purpose of this article is to present a staff development program designed to overcome challenges in implementing an electronic, tablet-based education program for patients with heart failure
Study protocol for two complementary trials of non-steroidal or opioid analgesia use for children aged 6 to 17 years with musculoskeletal injuries (the No OUCH study)
Introduction Musculoskeletal (MSK) injuries are a frequent cause for emergency department (ED) visits in children. MSK injuries are associated with moderate-to-severe pain in most children, yet recent research confirms that the management of children\u27s pain in the ED remains inadequate. Clinicians are seeking better oral analgesic options for MSK injury pain with demonstrated efficacy and an excellent safety profile. This study aims to determine the efficacy and safety of adding oral acetaminophen or oral hydromorphone to oral ibuprofen and interpret this information within the context of parent/caregiver preference. Methods and analysis Using a novel preference-informed complementary trial design, two simultaneous trials are being conducted. Parents/caregivers of children presenting to the ED with acute limb injury will be approached and they will decide which trial they wish to participate in: an opioid-inclusive trial or a non-opioid trial. Both trials will follow randomised, double-blind, placebo-controlled, superiority-trial methodology and will enrol a minimum of 536 children across six Canadian paediatric EDs. Children will be eligible if they are 6 to 17 years of age and if they present to the ED with an acute limb injury and a self-reported verbal Numerical Rating Scale pain score ≥5. The primary objective is to determine the effectiveness of oral ibuprofen+oral hydromorphone versus oral ibuprofen+oral acetaminophen versus oral ibuprofen alone. Recruitment was launched in April 2019. Ethics and dissemination This study has been approved by the Health Research Ethics Board (University of Alberta), and by appropriate ethics boards at all recruiting centres. Informed consent will be obtained from parents/guardians of all participants, in conjunction with assent from the participants themselves. Study data will be submitted for publication regardless of results. This study is funded through a Canadian Institutes of Health Research grant. Trial registration number NCT03767933, first registered on 07 December 2018
