Facing the Future: the Changing Shape of Academic Skills Support at Bournemouth University
No full textThis paper explores the potential impact of changes to higher education in England on student expectations, engagement, lifestyles and diversity, and outlines implications for the development of digital literacy within academic skills support at Bournemouth University (BU). We will investigate how tackling resource constraints with organisational change can also enable efficient, centralised provision of support materials that utilise networks to overcome the risk of fragmented support for digital literacy. We will also look at how changing delivery modes for support can accommodate changing student lifestyles whilst tackling a weakness of centralised support for digital literacy: that it can become detached from the student’s subject-focused academic practice. Finally we will explore how involving students in developing support can help us to face changes to student expectations and engagement whilst ensuring that materials are authentic and speak to learners in their own voice
Cardiovascular effects of marine omega-3 fatty acids
No full textMuch evidence shows that the marine omega-3 fatty acids eicosapentaenoic acid and docosahexaenoic acid have beneficial effects in various cardiac disorders, and their use is recommended in guidelines for management of patients after myocardial infarction. However, questions have been raised about their usefulness alongside optimum medical therapies with agents proven to reduce risk of cardiac events in high-risk patients. Additionally, there is some evidence for a possible pro-arrhythmic effect in subsets of cardiac patients. Some uncertainly exists about the optimum dose needed to obtain beneficial effects and the relative merit of dietary intake of omega-3 polyunsaturated fatty acids versus supplements. We review evidence for the effects of omega-3 polyunsaturated fatty acids on various cardiac disorders and the risk factors for cardiac disease. We also assess areas of uncertainty needing further researc
Omega-3 fatty acid supplementation does not reduce risk of atrial fibrillation after coronary artery bypass surgery: a randomized, double-blind, placebo-controlled clinical trial
No full textBackground—Omega-3 polyunsaturated fatty acids (n-3 PUFA) have been reported to reduce the risk of sudden cardiac
death presumed to be due to fatal ventricular arrhythmias, but their effect on atrial arrhythmias is unclear.
Methods and Results—Patients (n108) undergoing coronary artery bypass graft surgery were randomly assigned to
receive 2 g/d n-3 PUFA or placebo (olive oil) for at least 5 days before surgery (median, 16 days; range, 12 to 21
days). Phospholipid n-3 PUFA were measured in serum at study entry and at surgery and in right atrial appendage
tissue at surgery. Echocardiography was used to assess left ventricular function and left atrial dimensions.
Postoperative continuous ECG monitoring (Lifecard CF) for 5 days or until discharge, if earlier, was performed
with a daily 12-lead ECG and clinical review if patients remained in the hospital beyond 5 days. Lifecard
recordings were analyzed for episodes of atrial fibrillation (AF) 30 seconds (primary outcome). Clinical AF, AF
burden (% time in AF), hospital stay, and intensive care/high dependency care stay were measured as secondary
outcomes. One hundred three patients completed the study (51 in the placebo group and 52 in the n-3 PUFA group).
There were no clinically relevant differences in baseline characteristics between groups. n-3 PUFA levels were
higher in serum and right atrial tissue in the active treatment group. There was no significant difference between
groups in the primary outcome of AF (95% confidence interval [CI], 6% to 30%, P0.28) in any of the
secondary outcomes or in AF-free survival.
Conclusions—Omega-3 PUFA do not reduce the risk of AF after coronary artery bypass graft surgery
Centuries of transition
No full textThis review of Chris Wickham's Framing the Early Middle Ages situates the book within the context of his earlier writings on the transition to feudalism, and contrasts his explanation for and dating of the process with those of the two main opposing positions set out in Perry Anderson's Passages from Antiquity to Feudalism (1974) and Guy Bois's The Transformation of the Year One Thousand (1989). Although Framing modifies some of Wickham's earlier positions, it largely sidesteps explicit theoretical discussion for a compellingly detailed empirical study which extends to almost the entire territorial extent of the former Roman Empire. The review focuses on three main themes raised by Wickham's important work: the existence or otherwise of a `peasant'-mode of production and its relationship to the `Asiatic' mode; the nature of state-formation and the question of when a state can be said to have come into existence; and the rôle of different types of class-struggle - slave-rebellions, tax-revolts and peasant-uprisings - in establishing the feudal system

Unemployment Insurance and Unemployment: Implications of the Reemployment Bonus Experiments
No full textWe translate the results of the three reemployment bonus experiments that were conducted during the 1980s into (a) impacts of a 10-percentage point increase in the Unemployment Insurance (UI) replacement rate on the expected duration of unemployment; and (b) impacts of adding 1 week to the potential duration of UI benefits on the expected duration of unemployment. Our approach is to use an equilibrium search and matching model, calibrated using data from the bonus experiments and secondary sources. The results suggest that a 10-percentage point increase in the UI replacement rate increases the expected duration of unemployment by .3 to 1.1 week (a range consistent with, but only somewhat narrower than, the existing range of estimates), and that adding 1 week to the potential duration of UI benefits increases the expected duration of unemployment by .05 to .2 week (which is toward the low end of existing estimates).unemployment, insurance, bonus, experiments, Davidson, Woodbury
Maximizing Research Impact Through Institutional and National Open-Access Self-Archiving Mandates
No full textNo research institution can afford all the journals its researchers may need, so all articles are losing research impact (usage and citations). Articles made “Open Access,” (OA) by self-archiving them on the web are cited twice as much, but only 15% of articles are being spontaneously self-archived. The only institutions approaching 100% self-archiving are those that mandate it. Surveys show that 95% of authors will comply with a self-archiving mandate; the actual expe-rience of institutions with mandates has confirmed this. What institutions and funders need to mandate is that (1) immediately upon acceptance for publication, (2) the author’s final draft must be (3) deposited into the Institutional Repository. Only the depositing needs to be mandated; set-ting access privileges to the full-text as either OA or Restricted Access (RA) can be left up to the author. For articles published in the 93% of journals that have already endorsed self-archiving, access can be set as OA immediately; for the remaining 7%, authors can email the eprint in re-sponse to individual email requests automatically forwarded by the Repository
Millisecond accuracy video display using OpenGL under Linux
No full textTo measure people’s reaction times to the nearest millisecond, it is necessary to know exactly when
a stimulus is displayed. This article describes how to display stimuli with millisecond accuracy on a
normal CRT monitor, using a PC running Linux. A simple C program is presented to illustrate how this
may be done within X Windows using the OpenGL rendering system. A test of this system is reported
that demonstrates that stimuli may be consistently displayed with millisecond accuracy. An algorithm
is presented that allows the exact time of stimulus presentation to be deduced, even if there are relatively
large errors in measuring the display time
