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
Pregnancy as a source of discrimination: A comparative study of antidiscrimination legislation in the European Union and the United States of America.
While the antidiscrimination laws of the European Union (EU) and the United States of America (US) seek to prohibit pregnancy discrimination in the workplace, their approach to the problem has historically differed. US law has been defined by an ‘equal treatment’ approach. The contrasting EU laws reflect a holistic approach that seeks substantive equality by combining equal treatment with ‘special treatment’ measures, complemented by the strategy of gender mainstreaming.
This thesis sets out to examine the extent to which US antidiscrimination law is shifting towards a more holistic approach that seeks greater substantive equality for pregnant workers. This examination is carried out on two levels: firstly, this thesis will comparatively study the two distinct models of equality that exist to address sex discrimination in the EU and the US, with a view to highlighting differences and similarities, and the availability of alternative measures, or serious limitations in their approach to pregnancy discrimination.
Secondly, this thesis examines the antidiscrimination legislation that has been adopted and proposed on the national and state levels in the US, in order to draw attention to the increasing number of measures providing paid leave and workplace accommodations for pregnant workers, and imposing a duty to promote or achieve substantive equality. This examination is undertaken against a background of the distinct historical, legal, and conceptual context against which EU and US sex discrimination law has been adopted, and the discursive debate of feminist legal theorists regarding the role of law in both subordinating women, and in helping to end their inequality. EU and US law is studied in this wider context, because they have all been influential upon its development and provide a framework for assessing how far the trajectory of US antidiscrimination law is converging with that of the EU
A demonstration of mobile phone deployment to support the treatment of acutely ill children under five in Bushenyi district, Uganda
Background: Benefits of mobile phone deployment for children <5 in low resource settings remain unproven. The target population of the current demonstration study in Bushenyi District, Uganda, presented with acute fever, pneumonia, or diarrhoea and were treated by community health workers (CHWs) providing integrated community case management (iCCM).Methods: An observational study was conducted in five parishes (47 villages) served by CHWs well versed in iCCM with supplemental training in mobile phone use. Impact was assessed by quantitative measures and qualitative evaluation through household surveys, focus group discussions, and key informant interviews.Results: CHWs in targeted sites improved child healthcare through mobile phone use coupled with iCCM. Of acutely ill children, 92.6% were correctly managed. Significant improvements in clinical outcomes compared to those obtained by CHWs with enhanced iCCM training alone were unproven in this limited demonstration. Nonetheless, qualitative evaluation showed gains in treatment planning, supply management, and logistical efficiency. Provider confidence and communications were enhanced as was ease and accuracy of record keeping.Conclusion: Mobile phones appear synergistic with iCCM to bolster basic supportive care for acutely ill children provided by CHWs. The full impact of expanded mobile phone deployment warrants further evaluation prior to scaling up in low-resource settings.Keywords: mobile phone deployment, ill children under five, Bushenyi district, Ugand
A demonstration of mobile phone deployment to support the treatment of acutely ill children under five in Bushenyi district, Uganda.
Background: Benefits of mobile phone deployment for children <5 in
low-resource settings remain unproven. The target population of the
current demonstration study in Bushenyi District, Uganda, presented
with acute fever, pneumonia, or diarrhoea and were treated by community
health workers (CHWs) providing integrated community case management
(iCCM). Methods: An observational study was conducted in five parishes
(47 villages) served by CHWs well versed in iCCM with supplemental
training in mobile phone use. Impact was assessed by quantitative
measures and qualitative evaluation through household surveys, focus
group discussions, and key informant interviews. Results: CHWs in
targeted sites improved child healthcare through mobile phone use
coupled with iCCM. Of acutely ill children, 92.6% were correctly
managed. Significant improvements in clinical outcomes compared to
those obtained by CHWs with enhanced iCCM training alone were unproven
in this limited demonstration. Nonetheless, qualitative evaluation
showed gains in treatment planning, supply management, and logistical
efficiency. Provider confidence and communications were enhanced as was
ease and accuracy of record keeping. Conclusion: Mobile phones appear
synergistic with iCCM to bolster basic supportive care for acutely ill
children provided by CHWs. The full impact of expanded mobile phone

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
MRI-derived g-ratio and lesion severity in newly diagnosed multiple sclerosis
Myelin loss is associated with axonal damage in established multiple sclerosis. This relationship is challenging to study in vivo in early disease. Here, we ask whether myelin loss is associated with axonal damage at diagnosis, by combining non-invasive neuroimaging and blood biomarkers. We performed quantitative microstructural MRI and single molecule ELISA plasma neurofilament measurement in 73 patients with newly diagnosed, immunotherapy naïve relapsing-remitting multiple sclerosis. Myelin integrity was evaluated using aggregate g-ratios, derived from magnetization transfer saturation (MTsat) and neurite orientation dispersion and density imaging (NODDI) diffusion data. We found significantly higher g-ratios within cerebral white matter lesions (suggesting myelin loss) compared with normal-appearing white matter (0.61 vs 0.57, difference 0.036, 95% CI 0.029 to 0.043, p &lt; 0.001). Lesion volume (Spearman’s rho rs= 0.38, p &lt; 0.001) and g-ratio (rs= 0.24 p &lt; 0.05) correlated independently with plasma neurofilament. In patients with substantial lesion load (n = 38), those with higher g-ratio (defined as greater than median) were more likely to have abnormally elevated plasma neurofilament than those with normal g-ratio (defined as less than median) (11/23 [48%] versus 2/15 [13%] p &lt; 0.05). These data suggest that, even at multiple sclerosis diagnosis, reduced myelin integrity is associated with axonal damage. MRI-derived g-ratio may provide useful additional information regarding lesion severity, and help to identify individuals with a high degree of axonal damage at disease onset. York, Martin et al. simultaneously measured g-ratio and plasma neurofilament in 73 relapsing-remitting multiple sclerosis patients at diagnosis using advanced MRI and single molecule ELISA. They demonstrate that g-ratio of cerebral white matter lesions varies at diagnosis, and show that high g-ratio of lesions is associated with elevated plasma neurofilament
Examination of Late Palaeolithic archaeological sites in northern Europe for the preservation of cryptotephra layers
We report the first major study of cryptotephra (non-visible volcanic ash layers) on Late Palaeolithic archaeological sites in northern Europe. Examination of 34 sites dating from the Last Termination reveals seven with identifiable cryptotephra layers. Preservation is observed in minerogenic and organic deposits, although tephra is more common in organic sediments. Cryptotephra layers normally occur stratigraphically above or below the archaeology. Nearby off-site palaeoclimate archives (peat bogs and lakes <0.3 km distant) were better locations for detecting tephra. However in most cases the archaeology can only be correlated indirectly with such cryptotephras. Patterns affecting the presence/absence of cryptotephra include geographic position of sites relative to the emitting volcanic centre; the influence of past atmospherics on the quantity, direction and patterns of cryptotephra transport; the nature and timing of local site sedimentation; sampling considerations and subsequent taphonomic processes. Overall, while tephrostratigraphy has the potential to improve significantly the chronology of such sites many limiting factors currently impacts the successful application
Patient non-attendance at urgent referral appointments for suspected cancer and its links to cancer diagnosis and one year mortality : A cohort study of patients referred on the Two Week Wait pathway
BACKGROUND: The 'Two Week Wait' policy aims to ensure patients with suspected cancer are seen within two weeks of referral. However, patient non-attendance can result in this target being missed. This study aimed to identify predictors of non-attendance; and analyse the relationship between attendance and outcomes including cancer diagnosis and early mortality. METHODS: A cohort study of 109,433 adults registered at 105 general practices, referred to a cancer centre within a large NHS hospital trust (April 2009 to December 2016) on the 'Two Week Wait' pathway. RESULTS: 5673 (5.2%) patients did not attend. Non-attendance was largely predicted by patient factors (younger and older age, male gender, greater deprivation, suspected cancer site, earlier year of referral, greater distance to the hospital) over practice factors (greater deprivation, lower Quality and Outcomes Framework score, lower cancer conversion rate, lower cancer detection rate). 10,360 (9.6%) patients were diagnosed with cancer within six months of referral (9.8% attending patients, 5.6% non-attending patients). Among these patients, 2029 (19.6%) died within 12 months of diagnosis: early mortality risk was 31.3% in non-attenders and 19.2% in attending patients. CONCLUSIONS: Non-attendance at urgent referral appointments for suspected cancer involves a minority of patients but happens in predictable groups. Cancer diagnosis was less likely in non-attending patients but these patients had worse early mortality outcomes than attending patients. The study findings have implications for cancer services and policy
A Downstream CpG Island Controls Transcript Initiation and Elongation and the Methylation State of the Imprinted Airn Macro ncRNA Promoter
A CpG island (CGI) lies at the 5′ end of the Airn macro non-protein-coding (nc) RNA that represses the flanking Igf2r promoter in cis on paternally inherited chromosomes. In addition to being modified on maternally inherited chromosomes by a DNA methylation imprint, the Airn CGI shows two unusual organization features: its position immediately downstream of the Airn promoter and transcription start site and a series of tandem direct repeats (TDRs) occupying its second half. The physical separation of the Airn promoter from the CGI provides a model to investigate if the CGI plays distinct transcriptional and epigenetic roles. We used homologous recombination to generate embryonic stem cells carrying deletions at the endogenous locus of the entire CGI or just the TDRs. The deleted Airn alleles were analyzed by using an ES cell imprinting model that recapitulates the onset of Igf2r imprinted expression in embryonic development or by using knock-out mice. The results show that the CGI is required for efficient Airn initiation and to maintain the unmethylated state of the Airn promoter, which are both necessary for Igf2r repression on the paternal chromosome. The TDRs occupying the second half of the CGI play a minor role in Airn transcriptional elongation or processivity, but are essential for methylation on the maternal Airn promoter that is necessary for Igf2r to be expressed from this chromosome. Together the data indicate the existence of a class of regulatory CGIs in the mammalian genome that act downstream of the promoter and transcription start
