Developmental dyslexia,cerebellar/vestibular brain function and possible links to exercise-based interventions: a review     

Debbie Pope  Helen Whiteley 《欧洲特需教育杂志》2013,28(1):109-123

The Phonological Processing Deficit (PPD) hypothesis remains the most influential theory to explain why some children fail to acquire appropriate reading skills. However, current research suggests that there may be other deficits operating, and that the phonological processing deficit may be just one manifestation of a deeper underlying anatomical syndrome that originates in the cerebellar or vestibular areas of the brain. Claims that exercise regimes or programmes of vestibular stimulation may provide a ‘cure’ for developmental dyslexia (specific reading difficulties) prompt scepticism among the scientific community and raise concerns about the exploitation of vulnerable parents. The paper provides a review of research into the causes of specific reading difficulties at the behavioural, cognitive and biological level of explanation, and considers whether or not there is any theoretical basis for the use of exercise-based intervention programmes. Following consideration of recent findings from a range of scientific disciplines, it is concluded that such ‘unconventional’ methods of intervention may draw some theoretical support from the scientific literature, although researchers are cautioned to be wary of comorbidity issues. It is also concluded that more rigorous and independent evaluations of the success (or otherwise) of exercise-based interventions are needed.  相似文献

Conceptualizing curriculum management in an effective secondary school: a Western Australian case study     

Clive Dimmock  Helen Wildy 《Curriculum Journal》2013,24(3):297-323

ABSTRACT

This paper investigates the linkages between management processes and the curriculum using an academically effective secondary school as a case study. The aims of the study are twofold. First, in view of the acknowledged importance governments and others place on the quality of school leadership and management on the one hand and curriculum, teaching and learning reforms on the other, there is a need for empirical data as to how school leaders and managers work to secure improvements in curriculum, teaching and learning. This study purports to provide such data. The second aim acknowledges the need to develop conceptual frameworks and data collection instruments as aids to better understanding of complex relationships within school organizations.two deputy principals do play an indirect and important part in promoting academic performance by reinforcing school values in a wide variety of ways. Third, curriculum management is the responsibility of senior teachers and there is tight linkage between both senior teachers and teachers and high quality teaching and learning. Finally, the loose linkage between departments, and also between departments and senior management, provides little opportunity for a school‐wide approach to curriculum matters. It is evident that a whole‐school curriculum management perspective is absent in this school.  相似文献

Optofluidic planar reactors for photocatalytic water treatment using solar energy     

Lei L  Wang N  Zhang XM  Tai Q  Tsai DP  Chan HL 《Biomicrofluidics》2010,4(4):43004

Optofluidics may hold the key to greater success of photocatalytic water treatment. This is evidenced by our findings in this paper that the planar microfluidic reactor can overcome the limitations of mass transfer and photon transfer in the previous photocatalytic reactors and improve the photoreaction efficiency by more than 100 times. The microreactor has a planar chamber (5 cm×1.8 cm×100 μm) enclosed by two TiO(2)-coated glass slides as the top cover and bottom substrate and a microstructured UV-cured NOA81 layer as the sealant and flow input∕output. In experiment, the microreactor achieves 30% degradation of 3 ml 3×10(-5)M methylene blue within 5 min and shows a reaction rate constant two orders higher than the bulk reactor. Under optimized conditions, a reaction rate of 8% s(-1) is achieved under solar irradiation. The average apparent quantum efficiency is found to be only 0.25%, but the effective apparent quantum efficiency reaches as high as 25%. Optofluidic reactors inherit the merits of microfluidics, such as large surface∕volume ratio, easy flow control, and rapid fabrication and offer a promising prospect for large-volume photocatalytic water treatment.  相似文献   

Release monitoring of single cells on a microfluidic device coupled with fluorescence microscopy and electrochemistry     

Shi BX  Wang Y  Lam TL  Huang WH  Zhang K  Leung YC  Chan HL 《Biomicrofluidics》2010,4(4):43009

A method for monitoring the biological exocytotic phenomena on a microfluidic system was proposed. A microfluidic device coupled with functionalities of fluorescence imaging and amperometric detection has been developed to enable the real-time monitoring of the exocytotic events. Exocytotic release of single SH-SY5Y neuroblastoma cells was studied. By staining the cells located on integrated microelectrodes with naphthalene-2,3-dicarboxaldehyde, punctuate fluorescence consistent with localization of neurotransmitters stored in vesicles was obtained. The stimulated exocytotic release was successfully observed at the surface of SH-SY5Y cells without refitting the commercial inverted fluorescence microscope. Spatially and temporally resolved exocytotic events from single cells on a microfluidic device were visualized in real time using fluorescence microscopy and were amperometrically recorded by the electrochemical system simultaneously. This coupled technique is simple and is hoped to provide new insights into the mechanisms responsible for the kinetics of exocytosis.  相似文献
