    Eliciting the institutional myth: exploring the ethos of ‘the university’ in Germany and England

    Get PDF
    This paper is situated in relation to a critical mass of largely censorious commentary around global policy trends purportedly undermining, or even realigning, universities’ ‘traditional’ ethos, but where the student perspective on this appears to have been largely ignored. Drawing on interviews with German and English undergraduates, it applies the neo-institutional theory of organizational fields supported by regulative, cognitive, and normative pillars (Scott 1995. Institutions and Organi zations. Thousand Oaks: Sage). The latter pillar, representing a sector’s values, methods, and goals, is of particular interest here, and it will be argued that this and an ethos may correspond. The findings show that a sense of the participants’ understanding of a university ethos/normative pillar could be discerned, with significant convergence between the two groups. However at the same time there was also divergence both within and between them, and this raises a number of novel empirical and theoretical questions

    Disadvantaged by degrees? How Widening Participation students are not only hindered in accessing HE, but also during – and after – university.

    Get PDF
    There is no shortage of literature addressing the range of reasons why more disadvantaged groups are underrepresented in higher education – and particularly elite universities – in the UK, and it is clear that this has little to do with any real deficiency in terms of ability. This paper begins with an overview of this issue but then extends the argument beyond widening participation at the point of access. It raises concerns emerging from two relatively underresearched areas in the literature which indicate that ‘widening participation’ – WP – students are faced with greater inequalities than their more affluent peers both during their undergraduate degrees as well as beyond them. Although the focus here is on the UK, this topic and many of its themes will be familiar to educationalists and HE practitioners in other countries

    Comparing the impact of primary care practice design in two inner city UK homelessness services

    Background: Specialist homeless primary health care services in the United Kingdom have arisen from the need for bespoke approaches to providing health care for people experiencing homelessness but descriptions of the design characteristics of homeless health services together with associated long-term condition (LTC) prevalence, health care utilization, and prescribing remain unexplored, thereby limiting our understanding of potential impact of service configuration on outcomes. Aim: Description of specialist homeless general practitioner services in Glasgow and Edinburgh, in terms of practice design (staff, skill mix, practice systems of registration, and follow-up); and exploration of the potential impact of differences on LTC prevalence, health care utilization, and prescribing. Method: Patient data were collected from computerized general practitioner records in Glasgow (2015, n = 133) and Edinburgh (2016, n = 150). Homeless health service configuration and anonymized patient data, including demographics, LTCs service utilization, and prescribing were summarized and compared. Results: Marked differences in infrastructure emerged between 2 practices, including the patient registration process, segmentation versus integration of services, recording systems, and the availability of staff expertise. Patient characteristics differed in terms of LTC diagnoses, health care utilization and prescribing. Higher rates of recorded mental health and addiction problems were found in Edinburgh, as well as higher rates of physical LTCs, for example, cardiovascular and respiratory conditions. There were significantly higher rates of consultations with nurses and other staff in Edinburgh, although more patients had consultations with pharmacists in Glasgow. Medication adherence was low in both cohorts, and attendance at referral appointments was particularly poor in Glasgow. Conclusion: Service design and professional skill mix influence recording of LTCs, service uptake, and identification and management of health conditions. Service configuration, professional skill mix, and resources may profoundly affect diagnoses, utilization of health care, and prescribing. Attention to homeless service design is important when providing care to this disadvantaged patient group

    Reactive oxygen species induce virus-independent MAVS-oligomerization in systemic lupus erythematosus

    The increased expression of genes induced by type I interferon (IFN) is characteristic of viral infections and systemic lupus erythematosus (SLE). We showed that mitochondrial antiviral signaling (MAVS) protein, which normally forms a complex with retinoic acid gene I (RIG-I)–like helicases during viral infection, was activated by oxidative stress independently of RIG-I helicases. We found that chemically generated oxidative stress stimulated the formation of MAVS oligomers, which led to mitochondrial hyperpolarization and decreased adenosine triphosphate production and spare respiratory capacity, responses that were not observed in similarly treated cells lacking MAVS. Peripheral blood lymphocytes of SLE patients also showed spontaneous MAVS oligomerization that correlated with the increased secretion of type I IFN and mitochondrial oxidative stress. Furthermore, inhibition of mitochondrial reactive oxygen species (ROS) by the mitochondria-targeted antioxidant MitoQ prevented MAVS oligomerization and type I IFN production. ROS-dependent MAVS oligomerization and type I IFN production were reduced in cells expressing the MAVS-C79F variant, which occurs in 30% of sub-Saharan Africans and is linked with reduced type I IFN secretion and milder disease in SLE patients. Patients expressing the MAVS-C79F variant also had reduced amounts of oligomerized MAVS in their plasma compared to healthy controls. Together, our findings suggest that oxidative stress–induced MAVS oligomerization in SLE patients may contribute to the type I IFN signature that is characteristic of this syndrome

    Optical Sensor for Diverse Organic Vapors at ppm Concentration Ranges

    Get PDF
    A broadly responsive optical organic vapor sensor is described that responds to low concentrations of organic vapors without significant interference from water vapor. Responses to several classes of organic vapors are highlighted, and trends within classes are presented. The relationship between molecular properties (vapor pressure, boiling point, polarizability, and refractive index) and sensor response are discussed
