Beyond Volunteerism and Good Will: Examining the Commitment of Schoolbased Teachers to Distance Education

Two decades ago Newfoundland and Labrador introduced distance education in the K-12 environment. The program focused upon providing advanced-level courses to rural school students, and worked largely due to the widely known, but rarely documented significant amounts of content-based assistance from school based personnel. In the past seven years the province has moved to a virtual school model of distance education and more rural schools find that they must rely upon this virtual school to offer academic-level courses to students with a wide range of abilities. This has created many new responsibilities for teachers that have also gone undocumented. Studies that document the duties and time required to provide support for this new models of distance education are vital, as research is suggesting that this school-based personnel is vital to student success

How Are They Doing?: Examining Student Achievement in Virtual Schooling

Six years ago the Centre for Distance Learning and Innovation began a virtual high school within the Canadian province of Newfoundland and Labrador. Designed primarily to provide courses in specialized areas to students in rural areas, where schools have difficulty in attracting second language, mathematics and science teachers. However, there has been some concern that the opportunities provided by this virtual high school are second rate or only able to cater to independent, self-motivated students. The purpose of the study is to examine the student achievement in standardized public exams and final course scores in the province between different delivery models to determine whether or not students are succeeding in the virtual high school environment at the same rate as their classroom counterparts

Long-term high fat feeding of rats results in increased numbers of circulating microvesicles with pro-inflammatory effects on endothelial cells

Obesity and type 2 diabetes lead to dramatically increased risks of atherosclerosis and CHD. Multiple mechanisms converge to promote atherosclerosis by increasing endothelial oxidative stress and up-regulating expression of pro-inflammatory molecules. Microvesicles (MV) are small ( < 1 μm) circulating particles that transport proteins and genetic material, through which they are able to mediate cell–cell communication and influence gene expression. Since MV are increased in plasma of obese, insulin-resistant and diabetic individuals, who often exhibit chronic vascular inflammation, and long-term feeding of a high-fat diet (HFD) to rats is a well-described model of obesity and insulin resistance, we hypothesised that this may be a useful model to study the impact of MV on endothelial inflammation. The number and cellular origin of MV from HFD-fed obese rats were characterised by flow cytometry. Total MV were significantly increased after feeding HFD compared to feeding chow (P< 0·001), with significantly elevated numbers of MV derived from leucocyte, endothelial and platelet compartments (P< 0·01 for each cell type). MV were isolated from plasma and their ability to induce reactive oxygen species (ROS) formation and vascular cell adhesion molecule (VCAM)-1 expression was measured in primary rat cardiac endothelial cells in vitro. MV from HFD-fed rats induced significant ROS (P< 0·001) and VCAM-1 expression (P= 0·0275), indicative of a pro-inflammatory MV phenotype in this model of obesity. These findings confirm that this is a useful model to further study the mechanisms by which diet can influence MV release and subsequent effects on cardio-metabolic health

The Straight Truth about Online Learning in the Straits: An Investigation into the Nature of Education in a Rural and Remote Region of Newfoundland and Labrador

This paper reports on a naturalistic research project that was conducted in response to the educational concerns of the coastal rural communities of Labrador Straits. The research project investigated the current provision of education available to the children and the youth of these communities and found that due to declining population, changing demographics, lack of qualified teaching staff in the region and several other interrelated factors, there was an increased reliance on online learning in the small rural schools of the Straits as well as other rural regions of the province

Determinants of health, health behaviours and demographic profile of patients attending an Australian university student-led osteopathy clinic.

BackgroundProfiles of health professions practice can inform pre-professional education, provide evidence to assist with interprofessional practice, and inform policy development. An understanding of the profile of patients seeking osteopathy care is emerging. Current research suggests that musculoskeletal presentations predominate with approximately one-third of patients presenting with co-morbid diseases. There is little data on these presentations in Australian osteopathy practice. This study aimed to describe the patient demographics, clinical presentations, health behaviours and determinants of health, including health literacy, of those attending for care at an Australian student-led osteopathy clinic.MethodsA convenience sample design was utilised where consecutive patients presenting for their initial consultation were invited to complete a health information questionnaire during 2016-2017. The questionnaire explored a range of health behaviours and the patient's health status. Data from the clinical records were also extracted to establish the presenting complaint, duration of the complaint and pertinent demographics. Descriptive statistics were generated for each variable.ResultsData were available for 1617 patients presenting for their initial consultation. The mean age of patients was 33.7 (±13.1) years with 55% (n = 887) identifying as female. Acute presentations predominated (n = 840, 52%), with presentations affecting the spine being the most common (57.8%). Most patients rated their health status as good to very good (75%). Approximately 7.5% of patients were identified as having low health literacy and 55.9% were currently suffering from one or more co-morbid presentations.ConclusionsThe demographic profile and presenting complaints of patients presenting to a student-led osteopathy clinic are largely consistent with other Australian private practice profiles. The current work also identified co-morbid presentations, and positive and negative health behaviours. Osteopaths may play a role in the management of, or referral for, these presentations where health behaviours require change, or management of co-morbid conditions is beyond the scope of practice. The increasing volume of patient profile literature globally suggests that osteopaths can play a substantial role in the management of musculoskeletal complaints. Further, osteopathy may play a role in screening determinants of health, and engage in multidisciplinary care to ensure those patients with co-morbid conditions or adverse health behaviours are managed appropriately

Pharmaceutical Pricing in Emerging Markets: Effects of Income, Competition, and Procurement

This paper analyzes determinants of ex-manufacturer prices for originator and generic drugs across a large sample of countries. We focus on drugs to treat HIV/AIDS, TB and malaria in middle and low income countries (MLICs), with robustness checks to other therapeutic categories and other countries. We examine effects of per capita income, income dispersion, number and type of therapeutic and generic competitors, and whether the drugs are sold to retail pharmacies vs. tendered procurement by NGOs. The cross-national income elasticity of prices is 0.4 across high and low income countries, but is only 0.15 between MLICs, implying that drugs are least affordable relative to income in the lowest income countries. Within-country income inequality contributes to relatively high prices in MLICs. Number of therapeutic and generic competitors only weakly affects prices to retail pharmacies, plausibly because uncertain quality leads to competition on brand rather than price. Tendered procurement attracts multinational generic suppliers and significantly reduces prices for originators and generics, compared to prices to retail pharmacies

Gain-of-function mutations in the UNC-2/CaV2α channel lead to excitation-dominant synaptic transmission in C. elegans

Mutations in pre-synaptic voltage gated calcium channels can lead to familial hemiplegic migraine type 1 (FHM1). While mammalian studies indicate that the migraine brain is hyperexcitable due to enhanced excitation or reduced inhibition, the molecular and cellular mechanisms underlying this excitatory/inhibitory (E/I) imbalance are poorly understood. We identified a gain-of-function (gf) mutation in the Caenorhabditis elegans CaV2 channel α1 subunit, UNC-2, which leads to increased calcium currents. unc-2(zf35gf) mutants exhibit hyperactivity and seizure-like motor behaviors. Expression of the unc-2 gene with FHM1 substitutions R192Q and S218L leads to hyperactivity similar to that of unc-2(zf35gf) mutants. unc-2(zf35gf) mutants display increased cholinergic-and decreased GABAergic-transmission. Moreover, increased cholinergic transmission in unc-2(zf35gf) mutants leads to an increase of cholinergic synapses and a TAX-6/calcineurin dependent reduction of GABA synapses. Our studies reveal mechanisms through which CaV2 gain-of-function mutations disrupt excitation-inhibition balance in the nervous system.Fil: Huang, Yung Chi.

A systematic review of interventions to support looked-after children in school

This is the author accepted manuscript. The final version is available from the publisher via the DOI in this record.A systematic review of interventions to support looked-after children in school included interventions that aimed to improve attainment, or prevent drop-out or exclusions, and those that aimed to reduce absenteeism in the care population. Studies were critically appraised and their results were considered. No study was found robust enough to provide evidence on effectiveness, but promising interventions were identified. The review highlights the lack of evidence in an area that has received a lot of policy attention in the past few years. Future evaluations need to be underpinned by lessons learned from existing evaluations, clearly defined theories and definitions, and by the views of professionals, researchers, policy-makers and young people in care

A Mokken analysis of the literacy in musculoskeletal problems questionnaire.

BACKGROUND: Limited health literacy is known to impact on medication adherence, hospital readmission and potentially poorer health outcomes. The literature on the health literacy of those with musculoskeletal conditions suggests greater functional limitations and increased pain levels. There are a number of measures of health literacy. One that specifically relates to musculoskeletal complaints is the Literacy in Musculoskeletal Problems (LiMP) questionnaire. The LiMP contains 9 multiple choice items that cover anatomy, musculoskeletal conditions and the diagnosis of musculoskeletal complaints. The aim of the study was to evaluate the dimensionality and internal structure of the LiMP in patients attending for osteopathy care at a student-led clinic, as a potential measure of musculoskeletal health literacy. METHOD: Three hundred and sixty-one (n = 361) new patients attending the Victoria University Osteopathy Clinic completed the LiMP and a demographic and health information questionnaire prior to their initial consultation. Mokken scale analysis, a nonparametric item response theory approach, was used to evaluate the dimensionality and structure of the LiMP in this population, to ascertain whether the questionnaire was measuring a single latent construct - musculoskeletal health literacy. McDonald's omega and Cronbach's alpha were calculated as the reliability estimations. The relationship between the LiMP and a single item screen of health literacy was also undertaken. RESULTS: The 9 items on the LiMP did not form a Mokken scale and the reliability estimations were below an acceptable level (alpha and omega <0.45). LiMP items 5 and 8 were more likely to be answered correctly by those with higher health literacy (p < 0.05), however the effect sizes were small (<0.20). CONCLUSION: Calculation of a total score for the LiMP, as advocated by the original authors, is not supported based on data in the present study. Further research is required to explore the relationship of the LiMP items to demographic and clinical data, and to other broader measures of health literacy. Further research may also develop a health literacy measure that is specific to patients seeking manual therapy care for musculoskeletal complaints

Life satisfaction and musculoskeletal complaints in a population seeking osteopathy care: consecutive sample of 611 patients.

BackgroundLife satisfaction is a component of the subjective well-being construct. Research consistently suggests that life satisfaction is associated with enhanced social benefits and improved health outcomes. However, its relationship to musculoskeletal health outcomes is underexplored. This study evaluates the life satisfaction of a patient population presenting with musculoskeletal complaints, and the relationship of life satisfaction with other health demographics and behaviours.MethodThe study used a consecutive sampling design. Patients attending the Victoria University Osteopathy Clinic (Melbourne, Australia) were invited to complete the PROMIS® General Life Satisfaction scale (GLSS) along with questions related to health demographics and behaviours.ResultsThe GLSS T-score was not significantly different for gender, being born outside of Australia, speaking English at home, or complaint chronicity.ConclusionsLife satisfaction did not appear to be related to a range of health and demographic variables in the current musculoskeletal pain cohort. The PROMIS® General Life Satisfaction scale could prove useful to explore the relationship between life satisfaction and treatment outcomes for musculoskeletal complaints
