Count Me In: The Dimensions of social inclusion through Culture, Media & Sport (Executive Summary)
This study was set up to examine claims made for the ability of cultural projects to promote social inclusion (cultural projects are here taken to include those incorporating sport, the arts, media, heritage and outdoor adventure). This was to be achieved primarily by collecting evidence from a sample of 14 projects selected from some 200 that had volunteered their services. The report to the governmentās Social Exclusion Unit (SEU) from the Policy Action Team (PAT10) (1999) noted the potential. In his foreword, Chris Smith (then Secretary of State for the Department for Culture Media and Sport (DCMS)) wrote: āā¦ art and sport can not only make a valuable contribution to delivering key outcomes of lower long term unemployment, less crime, better health and better qualifications, but can also help to develop the individual pride, community spirit and capacity for responsibility that enable communities to run regeneration programmes themselvesā. Similar statements have followed from other politicians, particularly in the recent Commons debate on sport and social exclusion (22/11/01), and again in the public health debate (13/12/01). However, the PAT 10 report also came to the same conclusion as previous commentators (e.g. Glyptis, 19893; Allison & Coalter, 19964; Long & Sanderson, 1998) that there is little āhardā evidence of the social benefits that accrue

How a turn to critical race theory can contribute to our understanding of 'race', racism and anti-racism in sport
As long as racism has been associated with sport there have been consistent, if not coordinated or coherent, struggles to confront its various forms. Critical race theory (CRT) is a framework established to challenge these racialized inequalities and racism in society and has some utility for anti-racism in sport. CRT's focus on social justice and transformation are two areas of convergence between critical race theorists and anti-racists. Of the many nuanced and pernicious forms of racism, one of the most obvious and commonly reported forms of racism in sport, racial abuse, has been described as a kind of dehumanizing process by Gardiner (2003), as those who are its target are simultaneously (re)constructed and objectified according to everyday myth and fantasy. However, this is one of the many forms of everyday racist experiences. Various forms of racism can be experienced in boardrooms, on television, in print, in the stands, on the sidelines and on the pitch. Many times racism is trivialized and put down as part of the game (Long et al., 2000), yet its impact is rarely the source of further exploration. This article will explore the conceptualization of 'race' and racism for a more effective anti-racism. Critical race theory will also be used to explore the ideas that underpin considerations of the severity of racist behaviour and the implications for anti-racism. Ā© The Author(s) 2010

Prediction of Treatment Response to Neoadjuvant Chemotherapy for Breast Cancer via Early Changes in Tumor Heterogeneity Captured by DCE-MRI Registration.
We analyzed DCE-MR images from 132 women with locally advanced breast cancer from the I-SPY1 trial to evaluate changes of intra-tumor heterogeneity for augmenting early prediction of pathologic complete response (pCR) and recurrence-free survival (RFS) after neoadjuvant chemotherapy (NAC). Utilizing image registration, voxel-wise changes including tumor deformations and changes in DCE-MRI kinetic features were computed to characterize heterogeneous changes within the tumor. Using five-fold cross-validation, logistic regression and Cox regression were performed to model pCR and RFS, respectively. The extracted imaging features were evaluated in augmenting established predictors, including functional tumor volume (FTV) and histopathologic and demographic factors, using the area under the curve (AUC) and the C-statistic as performance measures. The extracted voxel-wise features were also compared to analogous conventional aggregated features to evaluate the potential advantage of voxel-wise analysis. Voxel-wise features improved prediction of pCR (AUCā=ā0.78 (Ā±0.03) vs 0.71 (Ā±0.04), pā<ā0.05 and RFS (C-statisticā=ā0.76 (āĀ±ā0.05), vs 0.63 (āĀ±ā0.01)), pā<ā0.05, while models based on analogous aggregate imaging features did not show appreciable performance changes (pā>ā0.05). Furthermore, all selected voxel-wise features demonstrated significant association with outcome (pā<ā0.05). Thus, precise measures of voxel-wise changes in tumor heterogeneity extracted from registered DCE-MRI scans can improve early prediction of neoadjuvant treatment outcomes in locally advanced breast cancer
Reviewing research evidence and the case of participation in sport and physical recreation by black and minority ethnic communities
The paper addresses the implications of using the process of systematic review in the many areas of leisure where there is a dearth of material that would be admitted into conventional Cochrane Reviews. This raises important questions about what constitutes legitimate knowledge, questions that are of critical import not just to leisure scholars, but to the formulation of policy. The search for certainty in an area that lacks conceptual consensus results in an epistemological imperialism that takes a geocentric form. While clearly, there is a need for good research design whatever the style of research, we contend that the wholesale rejection of insightful research is profligate and foolhardy. A mechanism has to be found to capitalise on good quality research of whatever form. In that search, we draw upon our experience of conducting a review of the material available on participation in sport and physical recreation by people from Black and minority ethnic groups. The paper concludes with a proposal for a more productive review process that makes better use of the full panoply of good quality research available. Ā© 2012 Ā© 2012 Taylor & Francis
What\u27s In A Name? Selected Secondary English Teachers\u27 Experiences Of Engaging In Formative Assessment
Formative assessmentās evolution over the last 50 plus years has led to the ubiquitous use of the term and ostensibly its practice, yet very little research has specifically addressed teachersā experiences of formative assessment, particularly in the realm of secondary English. This studyās goal, therefore, was to gain insight into how teachers experience engaging in formative assessment. By exploring their experiences, this descriptive phenomenological study sought to discover what meaning selected teachers ascribe to formative assessment and to thereby elevate teachersā voices in the formative assessment conversation. This research question guided the study: What are secondary English teachersā lived experiences of engaging in formative assessment? To answer this question, I generated data from 12 secondary English teachers by conducting in-depth, semi-structured interviews and collecting lived experience descriptions. Collectively, their experiences revealed that they practice formative assessment as a multi-step process, undertaken to determine where students are in their learning and to inform their instruction. They experience formative assessment as integral to their instruction and value informal formative interactions and conversations that are embedded in daily instruction. They consider positive class culture essential for undertaking formative assessment and have concerns that grading, district-mandated formative assessments, and the term itself may be impediments to effectively undertaking formative assessment. Ultimately, these findings offer strong support for the studyās conceptual framework; fill a gap in the formative assessment research; and offer policy makers, instructional leaders, and educational researchers insight into how these teachers understand and practice formative assessment

Blood pressure and lifestyle in UK African-Caribbeans
Mortality statistics for the 1970s to 1980s have shown adult African-Caribbeans to be the highest risk group for hypertension and its most common outcome, stroke. The Department of Health has acknowledged hypertension in Affican-Canbbeans to be an important sub priority area in the Health o f the Nation's systolic blood pressure reduction programme. To date, there has been very little researched aetiological data on blood pressure in this ethnic group. The significance of lifestyle related factors to hypertension within the general population, has been accepted by The Health o f the Nation. These include diet, exercise, alcohol and smoking habits, obesity (body mass index), as-well-as socio-economic conditions. Health behaviour modifications are judged to offer an effective non-pharmacologic approach towards the prevention and management of hypertension. This study carried out 1994-1997, examined the association between systolic blood pressure and a number of lifestyle factors in a workforce group of 164 African-Caribbeans -138 women and 26 men.
Design: Information about lifestyle habits, and other related factors was collected from a survey, through face-to-face interviews, by a single observer, using pre-designed structured questionnaires. Blood pressure, heart rate, height, and weight were measured and recorded by the same (single), observer. Up to six repeated measurements and progress reports for subsets of the study group were done. Multivariate linear regression analysis was used to develop prediction models at significance levels of <0.05.
Results: Age related rise in blood pressure was evident, and age had the strongest independent linear relationship with systolic blood pressure (Pearsonās r = 0.43). The most significant (positive) lifestyle factor was body mass index by group (Spearmanās r = 0.26). Negative associations were found with alcohol and smoking habits. No association was found with levels of physical activity Unexpectedly a negative association was found with adding salt, (Spearmanās r = -0.23), but no association was found with dietary habits in general. Subjects who were least educated and had the lowest job grades were more predisposed to high blood pressure. Apart from brotherās blood pressure history, familial hypertension was not evident. Negative associations were found with factors relating to racism. UK-bom subjects generally recorded significantly lower blood pressures than their (usually older) non UK-bom African-Caribbeans colleagues, but this difference was marginalised with age adjusted analysis.
Conclusion: Apart from body mass index, lifestyle and other psycho-socio-economic factors examined generally did not contribute to high blood pressure in the subjects Some significance was found in the āwrong directionā, that is, negative when positive was anticipated. There was no indication that lifestyle related factors were of any greater significance to the blood pressure values of African-Caribbeans than has been reported for the general population. Findings reflected those reported by the OPCS for the general population. However, there is an urgent need for much more research in the area
Coordinate-space approach to the bound-electron self-energy: Self-Energy screening calculation
The self-energy screening correction is evaluated in a model in which the
effect of the screening electron is represented as a first-order perturbation
of the self energy by an effective potential. The effective potential is the
Coulomb potential of the spherically averaged charge density of the screening
electron. We evaluate the energy shift due to a , ,
, or electron screening a , ,
, or electron, for nuclear charge Z in the range . A detailed comparison with other calculations is made.Comment: 54 pages, 10 figures, 4 table
Talk the talk, walk the walk: Defining Critical Race Theory in research
Over the last decade there has been a noticeable growth in published works citing Critical Race Theory (CRT). This has led to a growth in interest in the UK of practical research projects utilising CRT as their framework. It is clear that research on 'race' is an emerging topic of study. What is less visible is a debate on how CRT is positioned in relation to methodic practice, substantive theory and epistemological underpinnings. The efficacy of categories of data gathering tools, both traditional and non-traditional is a discussion point here to explore the complexities underpinning decisions to advocate a CRT framework. Notwithstanding intersectional issues, a CRT methodology is recognisable by how philosophical, political and ethical questions are established and maintained in relation to racialised problematics. This paper examines these tensions in establishing CRT methodologies and explores some of the essential criteria for researchers to consider in utilising a CRT framework.
