Learning technology in Scottish higher education ‐ a survey of the views of senior managers, academic staff and ‘experts’

As part of an evaluation of the Scottish Learning Technology Dissemination Initiative (LTDI), a survey was conducted of the views of academic staff, members of computer‐assisted learning and staff development units, and senior managers in all Scottish higher education institutions (HEIs). Most respondents across all subject areas and types of institutions (including those who rated themselves as less experienced with use of C&IT in teaching than their colleagues) believed that learning technology (LT) had moderate to very high potential for improving the way in which students learn. Awareness of the various agencies which have been established to promote its use in HEIs was very high, with few staff being unaware of any of them. Senior staff largely agreed that the value of these approaches lay in the improvement or maintenance of quality rather than in creating efficiency gains. Whilst there was a mostly positive view of the value of learning technology there are still significant barriers to its uptake by staff, the most important being lack of time, infrastructure, software and training, plus a failure (perceived or actual) of institutions to value teaching. The rather pessimistic view of ‘experts’ of the willingness of their less committed colleagues to make use of learning technology contrasted with the generally positive responses obtained from a broad group of 1,000 academic staff on their awareness of and attitudes to it. An analysis of the SHEFC's Teaching Quality Assessment reports during 1992–6 revealed substantial variability between and within subject assessments as to whether specific comments were made about IT provision and its use in learning and teaching

A Comparative Study of Selected Physical Activity Skills on the Fifth and Sixth Grade at Storm Elementary School in San Antonio, Texas

The problem that was untaken in this study was to compare twenty boys from the fifth grade and twenty boys from the sixth grade at Ollie Storm Elementary School. A physical fitness test was given to determine if there were any differences in the skills that they performed according to their age, height, and weight. The importance of this study is to design some satisfactory measurement of achievement in selected physical skills for twenty boys of the fifth grade and twenty boys of the sixth grade. This was to get a true evaluation of their skills when compared to one another according to age, height, and weight. Since the only way to develop true physical fitness is through exercise, and by taking a critical look at the physical education program in Ollie Storm Elementary School, the program should be set up to suit and accomodate each individual. The problem has significance for the program of expansion of opportunities for improving the physical fitness of students at Ollie Storm Elementary School. Southers and others have stated: With the public conscience demanding of the health of the child and the school medical development of a simple economic but accurate means of assuring the child\u27s state of well being of a physical fitness is in order.5 The problem was a comparative study of physical fitness as measured by the American Association for Health, Physical Education and Recreation Youth Fitness Test. The problem of this thesis is to compare the physical fitness skills of the fifth, sixth grade boy students of Ollie Storm Elementary School, according to their age, height, and weight in performing these physical skills and to motivate the pupils toward a higher level of physical fitness. The following limitations were imposed upon the stud: (1) twenty boys from the fifth grade and twenty boys from the sixth grade, (2) the boys from each class will be selected according to age, height, and weight, (3) the study was limited to those who were physically fit in the past activities and those who enjoyed participation. 5S.

ANTIGENIC SPECIFICITIES ON MURINE SARCOMA CELLS : RECIPROCAL RELATIONSHIP BETWEEN NORMAL TRANSPLANTATION ANTIGENS (H-2) AND TUMOR-SPECIFIC IMMUNOGENICITY

Five methylcholanthrene-induced sarcomas were compared for their capacity to (a) absorb monospecific H-2 antisera, (b) induce tumor-specific immunity in syngeneic mice, and (c) metastasize early to the lungs. Comparison of the uptakes of monospecific H-2 antisera by the five different tumors showed that each of the tumors had a high, intermediate, or low surface representation of all of the seven specificities tested. No antigenic specificity was completely absent from any tumor, and no tumor had an unusually large or small amount of any individual specificity. The tumors could be placed in the sequence from one to five with respect to their H-2 antigenicity. The same five tumors were also ranked with respect to their capacity to induce a tumor-specific immune response in syngeneic mice. The tumor-specific immunogenicity had an inverse relationship to the H-2 antigenicity in that highly immunogenic tumors were those that had quantitatively less H-2 antigen on their surface and vice versa. Early metastases to the lung was associated with low levels of tumor-specific immunogenicity and high levels of H-2 antigenicity

Colombia Mi Pronostico Flood Application: Updating and Improving the Mi Pronostico Flood Web Application to Include an Assessment of Flood Risk

Colombia is a country with highly variable terrain, from the Andes Mountains to plains and coastal areas, many of these areas are prone to flooding disasters. To identify these risk areas NASA's Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) was used to construct a digital elevation model (DEM) for the study region. The preliminary risk assessment was applied to a pilot study area, the La Mosca River basin. Precipitation data from the National Aeronautics and Space Administration (NASA) Tropical Rainfall Measuring Mission (TRMM)'s near-real-time rainfall products as well as precipitation data from the Instituto de Hidrologia, Meteorologia y Estudios Ambientales (the Institute of Hydrology, Meteorology and Environmental Studies, IDEAM) and stations in the La Mosca River Basin were used to create rainfall distribution maps for the region. Using the precipitation data and the ASTER DEM, the web application, Mi Pronstico, run by IDEAM, was updated to include an interactive map which currently allows users to search for a location and view the vulnerability and current weather and flooding conditions. The geospatial information was linked to an early warning system in Mi Pronstico that can alert the public of flood warnings and identify locations of nearby shelters

Facet-joint injections for people with persistent non-specific low back pain (FIS) : study protocol for a randomised controlled feasibility trial

BACKGROUND: The role of injections of therapeutic substances into the back as treatment for low back pain is unclear. Facet joint injections are widely used despite the absence of evidence of sustained benefit. We hypothesise that facet joint injections might facilitate engagement with physiotherapist-led, best usual care (a combined physical and psychological programme) and is a clinically and cost-effective treatment for people with suspected low back pain of facet joint origin. METHODS/DESIGN: We present here the protocol for a randomised controlled feasibility trial for a main trial to test the above hypotheses. Patients referred to secondary care with persistent non-specific low back pain will be screened and invited to take part in the study. Those who meet the eligibility criteria will be invited for a physiotherapy assessment to confirm trial eligibility and for baseline data collection. All participants (n = 150) will be offered the best usual care package with physical and psychological components. Those randomised into the intervention arm (n = 75) will, in addition, receive intra-articular facet joint injections with local anaesthetic and steroids. Primary outcome data will be collected using daily and then weekly text messaging service for a pain score on a 0-10 scale. Questionnaire follow-up will be at 3, 6, and 12 months. Evaluation of trial processes and health economic analyses, including a value of information analysis, will be undertaken. The process evaluation will be mixed methods and will include the views of all stakeholders. DISCUSSION: Whilst this trial is a feasibility study it is currently one of the largest trials in this area. The outcomes will provide some evidence on the use of facet joint injections for patients with clinically diagnosed facet joint pain. TRIAL REGISTRATION: EudraCT identifier 2014-000682-50

Direct radiative forcing and atmospheric absorption by boundary layer aerosols in the southeastern US: model estimates on the basis of new observations

In an effort to reduce uncertainties in the quantification of aerosol direct radiative forcing (ADRF) in the southeastern United States (US), a field column experiment was conducted to measure aerosol radiative properties and effects at Mt. Mitchell, North Carolina, and at an adjacent valley site. The experimental period was from June 1995 to mid-December 1995. The aerosol optical properties (single scattering albedo and asymmetry factor) needed to compute ADRF were obtained on the basis of a procedure involving a Mie code and a radiative transfer code in conjunction with the retrieved aerosol size distribution, aerosol optical depth, and diffuse-to-direct solar irradiance ratio. The regional values of ADRF at the surface and top of atmosphere (TOA), and atmospheric aerosol absorption are derived using the obtained aerosol optical properties as inputs to the column radiation model (CRM) of the community climate model (CCM3). The cloud-free instantaneous TOA ADRFs for highly polluted (HP), marine (M) and continental (C) air masses range from 20.3 to −24.8, 1.3 to −10.4, and 1.9 to −13.4 W m−2, respectively. The mean cloud-free 24-h ADRFs at the TOA (at the surface) for HP, M, and C air masses are estimated to be −8±4 (−33±16), −7±4 (−13±8), and −0.14±0.05 (−8±3) W m−2, respectively. On the assumption that the fractional coverage of clouds is 0.61, the annual mean ADRFs at the TOA and the surface are −2±1, and −7±2 W m−2, respectively. This also implies that aerosols currently heat the atmosphere over the southeastern US by 5±3 W m−2 on annual timescales due to the aerosol absorption in the troposphere

Reducing Opioid Use for Chronic Pain With a Group-Based Intervention: A Randomized Clinical Trial

IMPORTANCE: Opioid use for chronic nonmalignant pain can be harmful. OBJECTIVE: To test whether a multicomponent, group-based, self-management intervention reduced opioid use and improved pain-related disability compared with usual care. DESIGN, SETTING, AND PARTICIPANTS: Multicentered, randomized clinical trial of 608 adults taking strong opioids (buprenorphine, dipipanone, morphine, diamorphine, fentanyl, hydromorphone, methadone, oxycodone, papaveretum, pentazocine, pethidine, tapentadol, and tramadol) to treat chronic nonmalignant pain. The study was conducted in 191 primary care centers in England between May 17, 2017, and January 30, 2019. Final follow-up occurred March 18, 2020. INTERVENTION: Participants were randomized 1:1 to either usual care or 3-day-long group sessions that emphasized skill-based learning and education, supplemented by 1-on-1 support delivered by a nurse and lay person for 12 months. MAIN OUTCOMES AND MEASURES: The 2 primary outcomes were Patient-Reported Outcomes Measurement Information System Pain Interference Short Form 8a (PROMIS-PI-SF-8a) score (T-score range, 40.7-77; 77 indicates worst pain interference; minimal clinically important difference, 3.5) and the proportion of participants who discontinued opioids at 12 months, measured by self-report. RESULTS: Of 608 participants randomized (mean age, 61 years; 362 female [60%]; median daily morphine equivalent dose, 46 mg [IQR, 25 to 79]), 440 (72%) completed 12-month follow-up. There was no statistically significant difference in PROMIS-PI-SF-8a scores between the 2 groups at 12-month follow-up (-4.1 in the intervention and -3.17 in the usual care groups; between-group difference: mean difference, -0.52 [95% CI, -1.94 to 0.89]; P = .15). At 12 months, opioid discontinuation occurred in 65 of 225 participants (29%) in the intervention group and 15 of 208 participants (7%) in the usual care group (odds ratio, 5.55 [95% CI, 2.80 to 10.99]; absolute difference, 21.7% [95% CI, 14.8% to 28.6%]; P < .001). Serious adverse events occurred in 8% (25/305) of the participants in the intervention group and 5% (16/303) of the participants in the usual care group. The most common serious adverse events were gastrointestinal (2% in the intervention group and 0% in the usual care group) and locomotor/musculoskeletal (2% in the intervention group and 1% in the usual care group). Four people (1%) in the intervention group received additional medical care for possible or probable symptoms of opioid withdrawal (shortness of breath, hot flushes, fever and pain, small intestinal bleed, and an overdose suicide attempt). CONCLUSIONS AND RELEVANCE: In people with chronic pain due to nonmalignant causes, compared with usual care, a group-based educational intervention that included group and individual support and skill-based learning significantly reduced patient-reported use of opioids, but had no effect on perceived pain interference with daily life activities.
