Although there is a debate about the importance of self-esteem in education, many primary teachers wish to help children who suffer from low self-esteem. However, in order to do this, we first have to identify such children. It is almost taken for granted that we can make quite accurate judgements based on the knowledge built up through day-to-day interactions with the children. This paper reports a small-scale study which looked at the match between teacher judgements of their pupils' self-esteem and the children's own self reports. The findings suggest we may not be as good at this as we would like to think.  相似文献

Three particular functions of higher education institutions are examined with reference to possible and appropriate tasks related to gerontological education and training. A series of matrices, each dealing with one component of educational gerontology and the three functions, provides a model that could serve as a means of allocating resources and identifying appropriate involvement of the institutions.  相似文献

The 2008 Educational Policy and Accreditation Standards identified 10 core competencies that all social work graduates should master. MSW programs found themselves with a need to identify knowledge, values, and skill statements that reflected what concentration-year students were expected to know and be able to do. In 2009 a group of educators convened at the Council on Social Work Education in Alexandria, VA to develop a model of advanced practice in clinical social work. This article describes the work group's process; identifies and describes the resulting advanced clinical knowledge, values, and skills statements; discusses the key debates and issues that arose during the development of the statements; and concludes with the implications for social work education and practice.  相似文献

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

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
