Psychometric Properties of the Full and Short Versions of the Quality of Life Instrument Package: Results from the Ontario province-wide study     

Dennis Raphael  Ivan Brown  Rebecca Renwick 《International Journal of Disability, Development & Education》1999,46(2):157-168

Results that bear upon the psychometric properties of the Quality of Life Instrument Package are presented. The reliability and validity of quality of life data from a probability sample of 500 persons with developmental disabilities in Ontario were assessed. The data indicate that most of the instruments found in the package met acceptable psychometric standards. In some cases, specific domain scores need to be interpreted with caution. The Full Version of the instrument seems appropriate for ongoing practical program planning with clients. The Short Version seems especially appropriate for evaluation and monitoring purposes.  相似文献

Makeover Or Takeover? The strange death of educational autonomy in neo-liberal England     

John Beck 《British Journal of Sociology of Education》1999,20(2):223-238

This paper is concerned with the erosion of educational autonomy in Britain in recent years. Employing an analytical framework derived mainly from the recent work of Basil Bernstein, it examines ways in which weakened boundaries between the educational and the economic/political spheres may be linked to attempts by government in Britain to take over, to an unprecedented degree, domains where educators and producers of knowledge have in the past enjoyed significant, although by no means unqualified, autonomy. Implications for changing educational identities are highlighted, as is Bernstein's central contention that we may be witnessing not merely presentational changes, but rather a fundamental redefinition of the relationship between knowledge and the knower. Certain aspects of the political and educational agenda of the present New Labour government are seen as continuing many of the directions of policy set by previous New Right administrations. It is suggested that such continuities at the level of politics and policy indicate the potency of neo-liberal forms of governmentality and the extent to which they have become entrenched. Postmodernist and modernist interpretations of these developments are briefly considered. Obstacles to effective contestation of the new modalities of control are discussed.  相似文献   

“I'm just not that great at science”: Science self-efficacy in arts and communication students     

Eileen McBride  W. Wyatt Oswald  Lindsey A. Beck  Amy Vashlishan Murray 《科学教学研究杂志》2020,57(4):597-622

Research in science education confirms the importance of self-efficacy in students' persistence and success in the sciences. The current study examined the role of science self-efficacy in nonspecialist, arts and communication-oriented students encountering science in a general education context. Participants (N = 275) completed a beginning- and end-of-semester survey including a Science Self-Efficacy Scale, a “connection to science” measure—the Inclusion of Science in Self Scale—and a Science Anxiety Scale. Participants also responded to two open-ended “sources of science efficacy” questions, and provided background/demographic information and access to their academic records. Results showed a significant increase in science self-efficacy and connection to science—although no change in science anxiety—over the course of the semester. The observed shift in self-efficacy for minority and international students was of particular note. These students started the course with lower confidence but, by the end of the semester, reported comparable science self-efficacy, and achieved similar grades to their White/Non-Hispanic and US resident classmates. Contrary to expectations, science self-efficacy did not predict performance in the class. However, students' self-reported sources of efficacy indicated increased confidence in using science in daily life, and confirmed the value of mastery experiences and of personally meaningful, student-centered course design in scaffolding student confidence. Results are discussed in terms of the individual and instructional factors that support science self-efficacy and student success in this unique, general education science environment.  相似文献   

Herceptin functionalized microfluidic polydimethylsiloxane devices for the capture of human epidermal growth factor receptor 2 positive circulating breast cancer cells     

Thierry B  Kurkuri M  Shi JY  Lwin LE  Palms D 《Biomicrofluidics》2010,4(3):32205

Building on recent breakthroughs in the field of microfluidic-based capture of rare cancer cells circulating in the blood, the present article reports on the use of Herceptin functionalized PDMS devices designed to efficiently capture from blood cancer cells, overexpressing the tyrosine kinase human epidermal growth factor receptor (HER2). The identification of patients overexpressing HER2 is critical as it typically associates with an aggressive disease course in breast cancer and poor prognosis. Importantly, HER2 positive patients have been found to significantly benefit from Herceptin (Trastuzumab), a humanized monoclonal antibody (MAb) against HER2. Disposable PDMS devices prepared using standard soft lithography were functionalized by the plasma polymerization of an epoxy-containing monomer. The epoxy-rich thin film (AGEpp) thus created could be conjugated with Herceptin either directly or through a polyethylene glycol interlayer. The properties and reactivity toward the monoclonal antibody conjugation of these coatings were determined using x-ray photoelectron spectroscopy; direct conjugation provided a good compromise in reactivity and resistance to biologically nonspecific fouling and was selected. Using the breast cancer cell line SK-BR-3 as a model for cells overexpressing HER2, the immunocapture efficacy of the Herceptin functionalized PDMS was demonstrated in model studies. Validation studies confirmed the ability of the device to efficiently capture (～80% capture yield) HER2 positive cells from full blood.  相似文献

IQ and neuropsychological predictors of academic achievement     

Susan Dickerson Mayes  Susan L. Calhoun  Edward O. Bixler  Dennis N. Zimmerman 《Learning and individual differences》2009,19(2):238-241

Word reading and math computation scores were predicted from Wechsler Abbreviated Scale of Intelligence Full Scale IQ, 10 neuropsychological tests, and parent attention deficit hyperactivity disorder (ADHD) ratings in 214 general population elementary school children. IQ was the best single predictor of achievement. In addition, Digit Span contributed significantly to reading prediction, and the Developmental Test of Visual-Motor Integration (VMI) and Coding contributed to math prediction. The remaining neuropsychological test scores did not significantly improve achievement prediction. Exploratory factor analysis yielded a general ability factor (comprising the four IQ subtests, Digit Span, VMI, reading, and math), five factors made up solely of subtests from single measures (Wisconsin Card Sorting Test, Stroop Color and Word Test, Gordon Diagnostic System, California Verbal Learning Test, and ADHD ratings), a factor consisting of Grooved Pegboard Test and Coding, and a factor consisting of Symbol Search and Animal Naming Test.  相似文献
