In most jurisdictions around the world,governments, in the name of economiccompetitiveness, have imposed comprehensive andquite dramatic changes on state schools. Mostchanges require a more centralized and rigorouscurriculum for pupils, a plethora ofaccountability measures and mandatoryin-service for teachers, and carefully definedand more onerous responsibilities for schoolleaders. The province of Ontario is nodifferent. Since 1995, its educational systemhas experienced quite revolutionary changes– all instituted with break-neck speed. At thesame time most schools in Ontario are employinginternal change strategies to address theseoutside pressures. These change forces havecoalesced to redefine the work and lives ofteachers and school leaders in many intendedand unintended ways. There is a substantialliterature on both external and internal changeforces, but very little has been written aboutthe conjunction of these change forces with thepersonal side of change for teachers andleaders. Based on two studies undertaken by theInternational Centre for Educational Change atthe Ontario Institute for Studies inEducation/University of Toronto, this paperexamines the unintended consequences of thesechange forces on the teachers and principals ofone secondary school in Ontario, Canada. Theteachers and leaders of Lord Byron High Schoolare not averse to change and are generallyquite content to do whatever is in the bestinterests of their students. The school has along history of innovation and change and areputation for attending to a wide diversity ofstudent needs.Through the use of multiple conceptual lenses,this paper addresses the unintendedconsequences of systemic change to the schooland its teachers and principals. At a time whenteacher shortages and teacher morale aregrowing problems for many educationaljurisdictions, this investigation will point toan urgent need to build better bridges ofunderstanding between policy makers and policyimplementers, and for researchers to provideresearch that is more sensitive to the work andlives of real people in real schools.  相似文献

ABSTRACT

Two related but distinct questions are often asked by educators as they try to make their schools more effective. These are: “Which of the many activities that we do have greater benefits for students?” and, “How can we make our schools better than they are now?” The first question focuses specifically on the impact of schools on student outcomes and the characteristics of effective schools, whereas the second addresses the implementation of change and school improvement. This article addresses the research related to these two questions and describes the application of this research in a large school district in Ontario, Canada.  相似文献

The ubiquitous fungus Aspergillus fumigatus causes allergic rhinitis, asthma, sinusitis and allergic bronchopulmonary aspergillosis. A number of major allergens from A. fumigatus are purified, but their structure-function role in the pathogenesis of disease is not known. Such information is essential for devising alternative therapy of fungal allergic diseases. In the present study, N-terminal and C-terminal deletion mutants ofAsp f 3 were constructed and their immunopathological responses studied in a mice model of allergy. Three mutants viz,Asp f 3 (aa 33–168), (aa 1–142), and (aa 23–142) were made by deleting certain amino acids from epitopic regions of full lengthAsp f 3, a major allergen of A. furnigatus. TheAsp f 3 and three mutated proteins were expressed in pET vector. The C-terminal deletion mutantAsp f 3 (aa 1–142) induced elevated IFN-γ but low levels of IL-4 by spleen cells. This mutant also showed significant downregulation of peripheral blood eosinophils and lung inflammation in immunized mice. The N-terminal deletion mutantAsp f 3 (aa 33–168) also exhibited an immuno-suppressive effect in terms of IgE production and induction of Th2 cytokine. The results indicate thatrAsp f 3 and its deletion mutants induced distinct immune-inflammatory responses in mice on challenge with these proteins. The non-IgE binding deletion mutants ofAsp f 3 (aa 1–142 and aa 33–168) could deviate Th2 immune response with a concomitant reduction in airway inflammation and infiltration of inflammatory cells.  相似文献

Behavioral and neurophysiological effects of a computer-aided morphological training protocol were examined in German-speaking children from Grades 3 to 9. Study 1 compared morphological awareness, reading, and spelling skills of 34 trained children with an untrained control group of 34 children matched for age, sex, and intelligence. All participants in the training group showed increases in morphological awareness, but only students from secondary school improved significantly in reading and spelling competences. In Study 2, a subsample of 8 trained children with poor spelling and reading abilities and 10 untrained children with higher language competencies underwent an electroencephalography testing involving three different language tasks. The training resulted in decreased theta-activity and increased activity in lower (7–10 Hz) and upper alpha (10–13 Hz). These findings reflect more effortful and attention-demanding processing after the training and suggest that children with poor spelling and reading abilities use the acquired morphological knowledge in terms of a compensatory strategy.  相似文献

The role of false belief in establishing children's social relationships during the transition to school was examined and compared to other social cognitive constructs. One hundred and fourteen 5‐year‐olds were recruited during their 1st year of school (Time 1); 106 children were retained 1 year later. False belief, emotion expression recognition, empathy, verbal ability, and peer‐rated social preference were measured at both times. False belief at Time 1 had a direct influence on concurrent social preference, over and above the influence of emotion expression recognition and empathy. False belief made no independent contribution to later social preference accounting for stability in social preference. The role of social cognitive development is discussed with respect to how children establish and maintain their position in a peer group.  相似文献

Diversity in sport, especially in relation to those who hold positions of power in interscholastic, intercollegiate, and professional sport, seems to be some what of an oxymoron. There is ample evidence that those who are not similar to the status quo that has long dominated such sport settings (i.e., white, heterosexual, male) are far less represented within positions of power in sport than they are in the population at large (Acosta & Carpenter, 1996; Washington. 1998). Furthermore, some suggest that the maintenance of the status quo goes beyond demographics and that homologous reproduction exists in attitudes. values, and leadership priorities among those in leadership positions in sport (Boutlier & San Giovanni, 1994). Because diversity and valuing diversity have received a greal deal of attention in the corporate world, this paper utilizes the business literature in an attempt to obtain a fresh perspective regarding the lack of diversity in one of the most criticized areas of sport, Division IA intercollegiate athletic organizations. A review of the literature resulted in a framework comprised of three dimensions: 1) noncompliance/compliance. 2) reactive diversity management; and 3) proactive diversity management. The framework is presented and described and its application to kinesiology, physical education. and sport is provided.  相似文献

>For a variety of reasons, psychological services are largely unavailable for older people who want help in coping with their interpersonal problems. Group counseling, when it is used, proves to be an effective and efficient method for meeting their needs. It also addresses the reality of the limited numbers of gerontologically trained professionals currently available in the field. A readily attainable, and largely untapped, resource for working with this population is older people themselves. The Continuum Center of Oakland University selects, trains, and supervises older men and women, who serve as paraprofessional group leaders in a self‐exploration program offered in a variety of community centers in the Detroit metropolitan area. The service and training programs, and some of the outcomes for clients and group leaders, are briefly described.  相似文献

Fungi are non-chlorophyllus microorganisms, which constitutes the main source of outdoor and indoor allergens. The antigens present in the spores and fragments of hyphae induce allergic responses in sensitized patients. The frequently recognized fungi associated with asthma include Alternaria, Cladosporium, Aspergillus, and Penicillium. With the advent of molecular biology techniques a number of fungal genes encoding relevant allergens have been cloned and the expressed allergens purified and characterized. In this review, we have presented the recent developments, where recombinant allergens have been used in the precise diagnosis of fungal allergy. We have also discussed the role played by these allergens and the T- and B-cell epitopes in the immune mechanism in fungal allergy.  相似文献

ABSTRACT

Talent identification (TID) and development (TDE) are large fields in professional soccer and in science. However, TID and TDE processes in youth academies have not been assessed in detail. As such, our aim was to survey professional clubs from around the world about their youth academy TID and TDE processes, with 29 clubs responding to the survey. TID and TDE processes changed as a function of player age. TID processes involved finding the best players locally and regionally, but for older players the search widened to nationally and internationally for the needs of the first team. Clubs used a multidisciplinary approach to TID, but more so with older players. Median number of academy players was 80, 100, and 66 players at 8–11 years, 12–16 years, and 17–21 years, respectively. Annual player turnover in the most recent season (selections/de-selections) was 29% across all age groups, with competition from other clubs cited as a limitation to TID. TDE processes involved weekly matches and 3–5 training sessions per week led by experienced, well-qualified coaches, with most clubs providing players with academic education, residency and transportation services. Our findings extend previous research assessing professional soccer youth academy TID and TDE processes by quantifying worldwide practices.  相似文献
