A survey of 569 young people with sickle cell disorder (SCD) in England has found such pupils miss considerable periods of time from school, typically in short periods of two or three days. One in eight has school absences equating to government‐defined ‘persistent absence’. Students with SCD report that they are not helped to catch up after these school absences. Half the children reported not being allowed to use the toilet when needed and not being allowed water in class; a third reported being made to take unsuitable exercise and being called lazy when tired. Children perceived both physical environment (temperature, school furniture) and social environment (being upset by teachers or other pupils) as triggers to episodes of their illness. Policy initiatives on school absences; preventive measures to ensure maintenance of good health; and measures to prevent perceived social attitudes precipitating ill health would also support children with other chronic illnesses at school.  相似文献

This is the first of a two-part position paper considering how knowledge management supports innovation. The focus of the first part is on diagnosis, and the development of management science and management practice in the 20th century. It is argued that systems need to be understood not as systems, but at the level of agent interaction, and that an emphasis on design should give way to an emphasis on emergence. The second part will develop these ideas further, with a focus on intervention.  相似文献

Performance measurement and communicating about it with the broader public is not self-evident if one looks at public services organizations (Hernon, P., 1998. The government performance and results act. Government Information Quarterly, 15: 153–156). In Belgium and the Netherlands, one organization that has been under constant surveillance from its stakeholders is the railroad company. Originally a national public service, it has changed through a European directive to operate in a liberalized transportation market. In this paper, we present the results of a qualitative study into what the Belgian and Dutch railway companies measure about their performance towards travelers, how they measure it, and specifically how they communicate it to their employees and stakeholders. Although we might expect the Dutch railway company (NS) to be more transparent than the Belgian railway company (NMBS/SNCB), in reality the two organizations do not differ that much from each other.  相似文献

An analysis is made of the reasons for excessive optimism concerning the potential of ICT to enhance levels of pupil achievement. After a review of evidence concerning the potential of ICT, a small-scale survey is reported that shows continuing problems in the adoption of ICT by teachers. It is concluded that more research is needed to improve the expectations and effectiveness of ICT provision and utilisation.  相似文献

Total acetylcholinesterase (AChE) activity was estimated in cerebrospinal fluid (CSF) using colorimetric method in 64 cases with tuberculous meningitis, (TBM) (n=64), pyogenic meningitis (PM) (n=60) and in controls (n=39) of paediatric age group. Mean CSF—AChE values of both TBM and PM were significantly higher when compared with controls (p<0.001) but no significant change between TBM and PM was observed (p<0.01). It is suggested that inflammation of meninges due to the infection may attribute to a change in the function of blood brain barrier (BBB) causing higher CSF—AChE values in these diseases.  相似文献

The aim of this study was to estimate the proportion of students who report themselves as highly test anxious in a sample of English secondary schools and whether this proportion differed by gender. Self-report test anxiety data were collected from 2435 secondary school students in 11 schools. Results showed that 16.4% of the sample reported themselves to be highly test anxious, with the proportion significantly higher in female students (22.5%) than male students (10.3%). Moderate gender differences were present in the worry and tension components of test anxiety and small differences in the social derogation component. While not all highly test anxious students might be at risk of underperformance and disengagement from school and academic activities, there may still be a sizable group of students who would benefit from specific support and intervention.  相似文献
