Vascular architecture:is it a helpful histopathological biomarker for hepatocellular carcinoma?

Hepatocellular carcinoma(HCC) remains one of the major public health problems throughout the world.Although originally associated with tumorigenic processes,liver angiogenesis has also been observed in the context of different liver in-flammatory,fibrotic,and ischemic conditions.Here we investigate the fractal dimension as a quantitator of non-Euclidean two-dimensional vascular geometry in a series of paired specimens of primary HCC and surrounding non-tumoral tissue,and discuss why this parameter might provide additional information regarding cancer behavior.The application of fractal geometry to the measurement of liver vascularity and the availability of a computer-aided quantitative method can eliminate errors in visual interpretation,and make it possible to obtain closer-to-reality numerals that are compulsory for any measurement process.     

Personal oral narratives in a special school curriculum: an analysis of key documents

Oral narrative is a critical skill for school achievement, for personal relationships and for social participation. However, it is downgraded in current and proposed National Curriculum frameworks, which fail to recognise its significance in development. Schools have flexibility to address the issue, which is of particular importance to pupils with special educational needs. This article explores the place of narrative in the policies, curriculum and assessment scheme of a special school catering for pupils across the range of ability. It is concluded that, while schools are free to prioritise according to pupils' needs, it is difficult to target oral narrative effectively in the absence of appropriate frameworks for setting goals and monitoring progress.     

The impact of dynamic assessment: an exploration of the views of children,parents and teachers

A qualitative research project was carried out to explore the views of children with special educational needs, their parents and teachers about one aspect of educational psychology practice: the dynamic assessment of cognitive skills. The research was carried out in a highly diverse and inclusive borough in East London, by Nicola Lawrence from Hounslow Educational Psychology Service, and Sharon Cahill from the University of East London. The views of nine children were sought through semi‐structured interviews regarding the process of dynamic assessment, supported with tools and techniques to facilitate discussion. The views of eight parents and seven teachers were also sought, through semi‐structured interviews and focus groups, regarding the psychological reports produced from dynamic assessment. Of the original findings acquired through thematic analysis of the data, those pertaining to the perceived impact of dynamic assessment of cognitive skills are reported. Dynamic assessment was reported to impact positively upon the child's emotional well‐being, self‐perceptions, approach to learning and social relationships, both directly, and through the subsequent intervention of parents and educators. Dynamic assessment, as well as providing instructionally useful information for parents and teachers, encouraged them to move beyond locating the problem within the child, to reconceptualising their special educational needs in context. As a result, parents and teachers became more positive and optimistic about the child, the current situation and the child's future. Dynamic assessment impacted upon the child's holistic needs, parenting and the development of inclusive practice in the classroom. It is concluded that from the perspective of service users, dynamic assessment forms a worthwhile and valuable part of educational psychology practice.     

Being strategic,being watchful,being determined: Black middle-class parents and schooling

This paper reports on qualitative data that focus on the educational strategies of middle-class parents of Black Caribbean heritage. Drawing on Bourdieu’s key concepts of habitus, capital and field, our focus is an investigation of the differences that are apparent between respondent parents in their levels of involvement with regard to schools. We conclude that, within a broadly similar paradigm of active involvement with and monitoring of schools, nuanced differences in parental strategising reflect whether academic achievement is given absolute priority within the home. This, in turn, reflects differential family habitus, and differential possession and activation of capitals.     

Three models,one goal: Assessing financial vulnerability in New Zealand amateur sports clubs

Financial vulnerability is a critical issue for nonprofit sports clubs due to clubs’ increasing costs and impediments to generating sufficient income. The first objective of this study is to derive a conceptual understanding of financial vulnerability for sports clubs by assessing three financial vulnerability models, two of which have previously been applied in the nonprofit sector generally. Two models are based on revenue patterns and expenditure, and the third is based on movements in Net Assets over four years. A second objective is to identify determinants of financial vulnerability within amateur sports clubs, focusing specifically on golf and football.The data to test these models were derived from the financial reports of 227 amateur sports clubs in New Zealand (98 football and 129 golf clubs). Each of the three models results in different predictive variables and has different explanatory strengths. For example, football clubs that were financially vulnerable under Model 1: Program Expenditure had declining revenues from members and trading, as well as high administration costs. Conversely, declining reserves are predictive in financially vulnerable golf clubs using Model 2: Net Assets. Model 3: Net Earnings was generalizable to both football and golf clubs. The explanatory variables were different between these sports, due to their different asset base and propensity to employ paid staff. The common variables those with oversight responsibilities should monitor against financial vulnerability are: an undue reliance on external, rather than member-based revenue, increasing debt, and excessive expenditure. Further research could extend this model to other sports and other jurisdictions.     

Examining the use of theory within educational technology and media research

Academic research in the areas of educational technology and media is often portrayed to be limited in terms of its use of theory. This short paper reports on data collected from a survey of 462 ‘research active’ academic researchers working in the broad area of educational technology and educational media. The paper explores their use (and non-use) of theory.
