The changing British society with new commitments to educational inclusion for disabled people should mean increased individual freedom of choice and greater chance of participation. However, juggling this with the continuing emphasis on education for the economy brings the danger of new forms of social exclusion of those who do have different needs and require additional support to take advantage of opportunities and make informed decisions about their professional futures. This contradiction encourages the deteriorating academic and career-oriented foresight of special schools and the inclusion of all disabled students in mainstream education, without providing enough support to cater for the diversity and differentiation it generates. This paper adds to this debate by reporting on the work in progress of a project funded by the European Social Fund, concerning the educational experiences of a group of young disabled people still in full-time mainstream or special education. It presents some personal accounts of the young people's perceptions of how their educational environment influences their personal aspirations for future careers and post-school choices. This research strives to give a voice to young disabled people, informing policy concerned with young people, education and transitions to work. 相似文献

In Ayurvedic medicine,Withania somnifera (Ashwagandha) is well known for its anti-stress activity. A passive rat experimental model, where the animals are subjected
to multiple stress of cold, hypoxia, restraint (C-H-R) has been developed to evaluate adaptogenic properties of various fractions
of W. somnifera root extracts. We have carried out extraction of roots of W. somnifera with water and further isolated one
of the active constituents called compound X and also tested its anti-stress activity in C-H-R model. The effect of administration
of W. somnifera water suspension (360 mg/Kg bw) and compound X (20mg/Kg bw) on the fall and recovery of colonic temperature
was noted. There was an increase of ≈38% and ≈54% in the time taken to attain Trec 23°C by rats given a single dose of fresh aqueous suspension and biologically active constituent (Compound X) respectively,
where as decrease in the recovery time to attain Trec 37°C is ≈13% and ≈33% respectively, as compared to control group. It is clear that rats treated with the fresh aqueous suspension
and compound X ofWithania somnifera, could withstand the multiple stress of C-H-R better than control group. 相似文献

In this article, different methods for generating and measuring high pressure are described. Empirical equations of state
(EOS) are illustrated for some standard materials.
P Ch Sahu (left) is at the Materials Science Division of Indira Gandhi Centre for Atomic Research, Kalpakkam. He is a specialist
in the field of high pressure science and is presently heading this activity at his institute.
His primary research areas are in high pressure phase transitions and in synthesis and study of novel materials under extreme
pressure and temperature conditions. 相似文献

Education and training play major roles in the lives of older adults. They serve preventive, facilitative, remedial, and preparatory functions. In this paper we present demographic changes related to education, outline motives and educational needs of older adults, examine the role of education in reducing the decline in mental functioning, discuss the need to engage underserved segments of the population, and offer suggestions for designing educational programs for older adults. 相似文献

Electrocatalytic oxygen evolution reaction(OER) is one of the crucial reactions for converting renewable electricity into chemical fuel in the form of hydrogen.To date,there is still a challenge in designing ideal cost-effective OER catalysts with excellent activity and robust durability.The hybridization of transition metal oxides and carbonaceous materials is one of the most effective and promising strategies to develop high-performance electrocatalysts.Herein,this work synthesized hybrids of ... 相似文献

When do adolescents' dreams of promising journeys through high school translate into academic success? This monograph reports the results of a collaborative effort among sociologists and psychologists to systematically examine the role of schools and classrooms in disrupting or facilitating the link between adolescents' expectations for success in math and their subsequent progress in the early high school math curriculum. Our primary focus was on gendered patterns of socioeconomic inequality in math and how they are tethered to the school's peer culture and to students' perceptions of gender stereotyping in the classroom. To do this, this monograph advances Mindset × Context Theory. This orients research on educational equity to the reciprocal influence between students' psychological motivations and their school-based opportunities to enact those motivations. Mindset × Context Theory predicts that a student's mindset will be more strongly linked to developmental outcomes among groups of students who are at risk for poor outcomes, but only in a school or classroom context where there is sufficient need and support for the mindset. Our application of this theory centers on expectations for success in high school math as a foundational belief for students' math progress early in high school. We examine how this mindset varies across interpersonal and cultural dynamics in schools and classrooms. Following this perspective, we ask:
- 1. Which gender and socioeconomic identity groups showed the weakest or strongest links between expectations for success in math and progress through the math curriculum?
- 2. How did the school's peer culture shape the links between student expectations for success in math and math progress across gender and socioeconomic identity groups?
- 3. How did perceptions of classroom gender stereotyping shape the links between student expectations for success in math and math progress across gender and socioeconomic identity groups?
