Open Science Happens Somewhere: Exploring the use of Science OER in Schools

This paper concerns a pilot exploring the use of openly licensed content in secondary schools. Specifically it looks at the use of the Open University’s (OU) OpenScienceLab (OSL) in two remote rural schools in the West Highlands of Scotland. OSL is a series of online experiments openly licensed for anyone to use, they are about learning through experimentation, and are part of a wider OU interest in how to support and develop inquiry based learning at a distance (Scanlon 2012). This area is of particular relevance to Scottish schools, as the underlying pedagogy of Curriculum for Excellence (CfE) promotes interdisciplinary thinking and learning through inquiry (Macintyre 2014). The idea of the pilot was to work on how “open content” might be used in schools to understand what openness might mean in and for educational practice. While our initial intention was simply to run these in schools after the first workshops it became apparent while the technical and licences were open and it was relatively clear how to do the experiments, people were uncertain how to use them in their educational practice. Emphasising the need to attend to Educational Practice as well as Openness in OEP. The pilot took a participatory design approach (Sanders and Westerlund 2011; Mor et.al 2012), to developing and support practices around the use of Open Educational Resources (OER) in classroom. Through a series of workshops and schools visits we looked to solve these problems from the classroom out, using the teachers experience to develop learning journeys that worked for teachers and pupils. With teachers we created a learning journey using the OU’s free platform OpenLearnWorks to wrap the experiments in a mixture of existing and newly developed OER. Two journeys were created, these will be run in two locations with with two sets of teachers in December 2014. The paper will report on the outcomes for pupils and teachers of this final stage. In doing so it will reflect on the participatory design process, highlighting the practices developed to support the use of open content, drawing out broader conclusions might support the use open materials in the classroom

Does Perceived Physical Attractiveness in Adolescence Predict Better Socioeconomic Position in Adulthood? Evidence from 20 Years of Follow Up in a Population Cohort Study

There is believed to be a 'beauty premium' in key life outcomes: it is thought that people perceived to be more physically attractive have better educational outcomes, higher-status jobs, higher wages, and are more likely to marry. Evidence for these beliefs, however, is generally based on photographs in hypothetical experiments or studies of very specific population subgroups (such as college students). The extent to which physical attractiveness might have a lasting effect on such outcomes in 'real life' situations across the whole population is less well known. Using longitudinal data from a general population cohort of people in the West of Scotland, this paper investigated the association between physical attractiveness at age 15 and key socioeconomic outcomes approximately 20 years later. People assessed as more physically attractive at age 15 had higher socioeconomic positions at age 36- in terms of their employment status, housing tenure and income - and they were more likely to be married; even after adjusting for parental socioeconomic background, their own intelligence, health and self esteem, education and other adult socioeconomic outcomes. For education the association was significant for women but not for men. Understanding why attractiveness is strongly associated with long-term socioeconomic outcomes, after such extensive confounders have been considered, is important. © 2013 Benzeval et al

Marxism Lost and Found: Alasdair MacIntyre and the Contemporary Debate

This paper examines the changing nature of debates that focus on the philosophy of Alasdair MacIntyre. Whilst outlining the history of MacIntyre’s engagement with Marxism and some of his key ideas, it argues that it is only recently that such debates have begun to rightfully recognise the continued relevance of Marxism to such discussions. I note that crucial aspects of MacIntyre’s politics and philosophy, particularly his opposition to capitalism, are now integral to the contemporary debate which helps in generating a shared vision of radical politics. Nevertheless, I point out that key disagreements still remain as to the role of Marxism within such debates, the validity of MacIntyre’s critique of Marxism, as well as the potentially problematic post-Marxist practice that MacIntyre advocates in After Virtue and beyond

Managerial Work in a Practice-Embodying Institution - The role of calling, the virtue of constancy

What can be learned from a small scale study of managerial work in a highly marginal and under-researched working community? This paper uses the ‘goods-virtues-practices-institutions’ framework to examine the managerial work of owner-directors of traditional circuses. Inspired by MacIntyre’s arguments for the necessity of a narrative understanding of the virtues, interviews explored how British and Irish circus directors accounted for their working lives. A purposive sample was used to select subjects who had owned and managed traditional touring circuses for at least 15 years, a period in which the economic and reputational fortunes of traditional circuses have suffered badly. This sample enabled the research to examine the self-understanding of people who had, at least on the face of it, exhibited the virtue of constancy. The research contributes to our understanding of the role of the virtues in organizations by presenting evidence of an intimate relationship between the virtue of constancy and a ‘calling’ work orientation. This enhances our understanding of the virtues that are required if management is exercised as a domain-related practice

Prevalence, incidence, primary care burden and medical treatment of angina in Scotland: age, sex and socioeconomic disparities: a population-based study

Objective: To examine the epidemiology, primary care burden and treatment of angina in Scotland. Design: Cross-sectional data from primary care practices participating in the Scottish continuous morbidity recording scheme between 1 April 2001 and 31 March 2002. Setting: 55 primary care practices (362 155 patients). Participants: 9508 patients with angina. Results: The prevalence of angina in Scotland was 28/1000 in men and 25/1000 in women (p < 0.05) and increased with age. The prevalence of angina also increased with increasing socioeconomic deprivation from 18/1000 in the least deprived category to 31/1000 in the most deprived group (p < 0.001 for trend). The incidence of angina was higher in men (1.8/1000) than in women (1.4/1000) (p = 0.004) and increased with increasing age and socioeconomic deprivation. Socioeconomically deprived patients (0.48 contacts/patient among the most deprived) were less likely than affluent patients (0.58 contacts/patient among the least deprived) to see their general practitioner on an ongoing basis p = 0.006 for trend). Among men, 52% were prescribed ß blockers, 44% calcium channel blockers, 72% aspirin, 54% statins and 36% angiotensin converting enzyme inhibitors or angiotensin receptor blockers. The corresponding prescription rates for women were 46% (p < 0.001), 41% (p = 0.02), 69% (p < 0.001), 45% (p < 0.001) and 30% (p < 0.001). Among patients < 75 years old 52% were prescribed a β blocker and 58% a statin. The corresponding figures for patients ≥ 75 years were 42% (p < 0.001) and 31% (p < 0.001). Conclusions: Angina is a common condition, more so in men than in women. Socioeconomically deprived patients are more likely to have angina but are less likely to consult their general practitioner. Guideline-recommended treatments for angina are underused in women and older patients. These suboptimal practice patterns, which are worst in older women, are of particular concern, as in Scotland more women (and particularly older women) than men have angina

Virus pneumonia of pigs

THIS disease is widespread in Western Australia and is undoubtedly a most serious source of economic loss to the pig industry. The effects of virus pneumonia are such that in badly managed herds, widespread pneumonic outbreaks and deaths are common. By contrast, in well managed herds, there is the more insidious problem of low or nil death rates, accompanied however by an appreciable fall in animal production

A Sub-cellular Localization of the Gene Product of the DNase-1 Locus in Drosophila melanogaster

A study was undertaken to determine the subcellular location of DNase-I, a major acid deoxyribonuclease in Drosophila melanogaster. Embryonic tissue used in these experiments was derived from a wild type strain and from a strain homozygous at the DNase-l locus (3-61.8) for the null activity allele, DNase-lnl24. The majority of total acid DNase and DNase-l activity is found in the small particulate fraction of tissue homogenates fractionated by differential centrifugation. The activity exhibits latency in these extracts indicating that it is membrane delimited. DNase-I activity also co-equilibrates in sucrose density gradients with acid phosphatase activity which, in D. melanogaster, is known to be lysosomal. These results suggest that DNase-l is localized largely within the Iysosomes of embryonic tissue. Functional implications of a lysosomal location for DNase-l are discussed
