The Legacy of ERA, Privatization and the Policy Ratchet
This article explores the ways in which the neo-liberal impetus toward the privatization of state schooling signalled in the Education Reform Act 1988 (ERA) has become embedded in the English school system. Four main points are made. First, that ERA itself was of huge strategic rather than substantive importance as far as privatization is concerned. Second, by tracing the lineage of privatization from ERA onwards a 'ratchet' effect of small and incremental policy moves can be identified, which have disseminated, embedded and naturalized privatization within public sector provision. Third, that while privatization has been taken up and taken much further by New Labour than it had been by the Conservatives there are differences between the two sets of governments in the role of privatization in education policy and the role of the state. Fourth, the participation of private providers in the planning and delivery of state services has put the private sector at the very heart of policy. At points the article draws upon interviews conducted with private sector providers. © 2008 Sage Publications
Quantitative assessment of the effects of a fixed 50% coronary artery stenosis on regional myocardial flow reserve and transmural distribution of blood flow
Experimental coronary artery stenoses produced by external constrictors that reduce vessel diameter by 50% under basal conditions have been shown to reduce myocardial hyperemic flow reserve. Because such lesions may exhibit dynamic increases in severity during coronary vasodilation, the results of these studies are not necessarily applicable to human patients with fixed, proximal coronary stenoses of similar baseline severity. Accordingly, the present study was conducted in 16 closed chest conscious pigs in order to assess the effects of a fixed, rigid 50% stenosis on maximal myocardial hyperemic flow and transmural distribution of blood flow. Eight pigs (Group I, stenosis) were instrumented with a 50% stenosis and eight were not (Group II, control). After obtaining control measurements of hemodynamics and regional myocardial blood flow (microsphere technique), adenosine was infused at doses of 100, 200 and 400 μg min-1(x 10 minutes at each dose) directly into the left anterior descending coronary bed distal to the stenosis (Group I) or at a similar level in animals without a stenosis. Hemodynamics and blood flow measurements were made at the 10th minute of each infusion level of adenosine.The results (mean ± 1 standard deviation) of the study were as follows. Under basal conditions, transmural, endocardial and epicardial flows (ml min-1g-1) in Group I pigs (1.48 ± 0.40, 1.51 ± 0.45 and 1.30 ± 0.35, respectively) did not differ significantly from respective flows in Group II pigs (1.56 ± 0.26, 1.57 ± 0.27 and 1.43 ± 0.30). Likewise baseline endocardial to epicardial flow ratios were comparable between the two groups (Group I = 1.16 ± 0.22 versus Group II =1.11 ± 0.09, p = NS). Transmural, endocardial and epicardial blood flow in Group I pigs increased to the same extent as respective flows in Group II pigs at each dose of adenosine tested. Maximal transmural, endocardial and epicardial flows in Group I pigs increased, respectively, to levels 3.56 ± 1.56, 3.56 ± 2.03 and 3.26 ± 1.16 above baseline values. Similar responses occurred in Group II (3.38 ± 1.02, 3.21 ± 0.91 and 3.25 ± 1.44, respectively). The endocardial/epicardial flow ratio in Group I at maximal vasodilation (1.20 ± 0.34) did not differ significantly from that in Group II (1.19 ± 0.34). Thus, the data demonstrate that in contrast to 50% stenoses formed with external coronary constrictors, fixed proximal 50% stenoses do not reduce maximal myocardial hyperemic flow reserve
Challenging the orthodoxy: union learning representatives as organic intellectuals
Teacher education and continuing professional development have become a key areas of controversy in England since the period of school sector restructuring following the 1988 Education Reform Act. More recently teacher training and professional development have often been used to promote and reinforce a narrow focus on the government’s ‘standards agenda’. However, the emerging discourse of ‘new professionalism’ has raised the profile of professional development in schools, and together with union learning representatives, there are opportunities to secure real improvements in teachers’ access to continuing professional development. This paper argues however that union learning representatives must go beyond advocating for better access to professional development and should raise more fundamental questions about the nature of professional development and the education system it serves. Drawing on Gramsci’s notion of the ‘organic intellectual’, the paper argues that union learning representatives have a key role as organisers of ideas – creating spaces in which the ideological dominance of current policy orthodoxy might be challenged
A Recovery Capital and Stress-Buffering Model for Post-deployed Military Parents
We tested a recovery capital model for military families employing the After Deployment, Adaptive Parenting Tools (ADAPT) randomized control trial, a longitudinal preventive intervention study of 336 post-deployed military parents. Recovery resources included measures of social capital (parenting support, observed partner support behaviors), personal capital (parenting efficacy, education), and community capital (the ADAPT behavioral parent-training intervention). We hypothesized higher levels of recovery capital would buffer the negative impact of military stress on growth in post-traumatic stress disorder (PTSD) symptoms for deployed and civilian parents. Outcome data were evaluated with three waves across 2-years. Hypotheses were tested with latent growth models in a structural equation modeling framework. Military stress was assessed by reports of exposure to combat and battle aftermath. Recovery capital was measured by reported support for parenting and direct observation of behavioral interactions during problem-solving discussions of deployment-related stressors. Fathers had higher levels of military-related stress and PTSD symptoms over time compared to mothers. Growth curve models showed that fathers were characterized by individual differences in 2-year average levels of PTSD symptoms while mothers were characterized by individual differences in initial status and linear growth trajectories. Results supported a recovery capital model. Higher levels of parenting efficacy and parenting support were associated with lower PTSD symptoms, representing common pathways for both mothers and fathers. Similarly, parenting support operated as a moderating buffer for both parents. That is, effects of military trauma exposure on psychological distress were lower for mothers and fathers with higher levels of parenting support relative to parents with lower levels. Regions of significance indicated that half a standard deviation above the mean of support was beneficial for mothers, while one and half standard deviations were needed to impact the effects of trauma on fathers’ PTSD. For mothers assigned to the ADAPT parent training intervention – but not fathers – the intervention was associated with linear reductions in PTSD symptoms over 2 years. The recovery capital model explained 36% of the variance in father outcomes and 46% for mothers. The intervention obtained a medium effect size in reducing mothers’ symptoms (d = 0.41). Implications for prevention and treatment within a recovery capital model are discussed
Recognising Desire: A psychosocial approach to understanding education policy implementation and effect
It is argued that in order to understand the ways in which teachers experience their work - including the idiosyncratic ways in which they respond to and implement mandated education policy - it is necessary to take account both of sociological and of psychological issues. The paper draws on original research with practising and beginning teachers, and on theories of social and psychic induction, to illustrate the potential benefits of this bipartisan approach for both teachers and researchers. Recognising the significance of (but somewhat arbitrary distinction between) structure and agency in teachers’ practical and ideological positionings, it is suggested that teachers’ responses to local and central policy changes are governed by a mix of pragmatism, social determinism and often hidden desires. It is the often underacknowledged strength of desire that may tip teachers into accepting and implementing policies with which they are not ideologically comfortable
The abolition of the General Teaching Council for England and the future of teacher discipline
With the abolition of the General Teaching Council for England in the 2011 Education Act, this article considers the future of teacher discipline in England. It provides a critique of the changes to the regulation of teacher misconduct and incompetence that draws on a Foucauldian framework, especially concerning the issue of public displays of discipline and the concomitant movement to more hidden forms. In addition, the external context of accountability that accompanies the reforms to teacher discipline are considered including the perfection of the panoptic metaphor presented by the changes to Ofsted practices such as the introduction of zero-notice inspections. The article concludes that the reforms will further move teachers from being occupational professionals to being organisational professionals marking them apart from comparable professions in medicine and law
Blockade of adenosine A2B receptors ameliorates murine colitis
Background and purpose: The adenosine 2B (A2B) receptor is the predominant adenosine receptor expressed in the colon. Acting through the A2B receptor, adenosine mediates chloride secretion, as well as fibronectin and interleukin (IL)-6 synthesis and secretion in intestinal epithelial cells. A2B receptor mRNA and protein expression are increased during human and murine colitis. However, the effect of the A2B receptor in the activation of the intestinal inflammatory response is not known. In this study, we examined the effect of A2B receptor antagonism on murine colitis. Experimental approach: Dextran sodium sulphate (DSS)-treated mice and piroxicam-treated IL-10/ mice were used as animal models of colitis. The A2B receptor-selective antagonist, ATL-801, was given in the diet. Key results: Mice fed ATL-801 along with DSS showed a significantly lower extent and severity of colitis than mice treated with DSS alone, as shown by reduced clinical symptoms, histological scores, IL-6 levels and proliferation indices. The administration of ATL-801 prevented weight loss, suppressed the inflammatory infiltrate into colonic mucosa and decreased epithelial hyperplasia in piroxicam-treated IL-10/ mice. IL-6 and keratinocyte-derived chemokine (KC) concentrations in the supernatants of colonic organ cultures from colitic mice were significantly reduced by ATL-801 administration. Conclusions and implications: Taken together, these data demonstrate that the intestinal epithelial A2B receptor is an important mediator of pro-inflammatory responses in the intestine and that A2B receptor blockade may be an effectiv
Crossing borders: new teachers co-constructing professional identity in performative times
This paper draws on a range of theoretical perspectives on the construction of new teachers’ professional identity. It focuses particularly on the impact of the development in many national education systems of a performative culture of the management and regulation of teachers’ work. Whilst the role of interactions with professional colleagues and school managers in the performative school has been extensively researched, less attention has been paid to new teachers’ interactions with students. This paper highlights the need for further research focusing on the process of identity co-construction with students. A key theoretical concept employed is that of liminality, the space within which identities are in transition as teachers adjust to the culture of a new professional workplace, and the nature of the engagement of new teachers, or teachers who change schools, with students. The authors argue that an investigation into the processes of this co-construction of identity offers scope for new insights into the extent to which teachers might construct either a teacher identity at odds with their personal and professional values, or a more ‘authentic’ identity that counters performative discourses. These insights will in turn add to our understanding of the complex range of factors impacting on teacher resilience and motivation
Creating citizen-consumers? Public service reform and (un)willing selves
About the book: Postmodern theories heralded the "death of the subject", and thereby deeply contested our intuition that we are free and willing selves. In recent times, the (free) will has come under attack yet again. Findings from the neuro- and cognitive sciences claim the concept of will to be scientifically untenable, specifying that it is our brain rather than our 'self' which decides what we want to do. In spite of these challenges however, the willing self has come to take centre stage in our society: juridical and moral practices ascribing guilt, or the organization of everyday life attributing responsibilities, for instance, can hardly be understood without taking recourse to the willing subject.
In this vein, the authors address topics such as the genealogy of the concept of willing selves, the discourse on agency in neuroscience and sociology, the political debate on volition within neoliberal and neoconservative regimes, approaches toward novel forms of relational responsibility as well as moral evaluations in conceptualizing autonomy
