While the call for teacher education students to learn about their students’ family and community lives remains urgent and compelling, educating teachers about the Other is tricky business. In this article I discuss the use of two performed ethnographies, Harriet’s House and Ana’s Shadow, to provide opportunities for teachers to learn about Other people’s families in ways that work against presenting a singular, dominant narrative of the Other’s experiences and positioning Other students as experts. Although the outcomes from educating teachers about Other people’s families are unpredictable and do not always disrupt the prior, potentially harmful, knowledges teachers bring with them to teaching, I argue, along with Kevin Kumashiro, that ongoing labour to stop the repetition of harmful knowledges is important anti-oppressive educational work. 相似文献

Interest in social learning has been fueled by claims of culture in wild animals. These remain controversial because alternative
explanations to social learning, such as asocial learning or ecological differences, remain difficult to refute. Compared
with laboratory-based research, the study of social learning in natural contexts is in its infancy. Here, for the first time,
we apply two new statistical methods, option-bias analysis and network-based diffusion analysis, to data from the wild, complemented
by standard inferential statistics. Contrary to common thought regarding the cognitive abilities of prosimian primates, our
evidence is consistent with social learning within subgroups in the ring-tailed lemur (Lemur catta), supporting the theory of directed social learning (Coussi-Korbel & Fragaszy, 1995). We also caution that, as the toolbox
for capturing social learning in natural contexts grows, care is required in ensuring that the methods employed are appropriate-in
particular, regarding social dynamics among study subjects. Supplemental materials for this article may be downloaded from

Preanalytical steps are the major sources of error in clinical laboratory. The analytical errors can be corrected by quality control procedures but there is a need for stringent quality checks in preanalytical area as these processes are done outside the laboratory. Sigma value depicts the performance of laboratory and its quality measures. Hence in the present study six sigma and Pareto principle was applied to preanalytical quality indicators to evaluate the clinical biochemistry laboratory performance. This observational study was carried out for a period of 1 year from November 2015–2016. A total of 1,44,208 samples and 54,265 test requisition forms were screened for preanalytical errors like missing patient information, sample collection details in forms and hemolysed, lipemic, inappropriate, insufficient samples and total number of errors were calculated and converted into defects per million and sigma scale. Pareto`s chart was drawn using total number of errors and cumulative percentage. In 75% test requisition forms diagnosis was not mentioned and sigma value of 0.9 was obtained and for other errors like sample receiving time, stat and type of sample sigma values were 2.9, 2.6, and 2.8 respectively. For insufficient sample and improper ratio of blood to anticoagulant sigma value was 4.3. Pareto`s chart depicts out of 80% of errors in requisition forms, 20% is contributed by missing information like diagnosis. The development of quality indicators, application of six sigma and Pareto`s principle are quality measures by which not only preanalytical, the total testing process can be improved. 相似文献

Thyroglobulin autoantibodies (TgAb) are estimated to detect potential interferences in thyroglobulin (Tg) immunoassays and also for the diagnosis of autoimmune thyroid disease. A user friendly and robust in-house solid-phase radioassay was standardized and parameters like sensitivity, reproducibility and stability were assessed. Further, it was validated and evaluated for the detection of autoantibodies in differentiated thyroid cancer (DTC) patients. Totally 301 samples received in our laboratory for routine serum Tg estimation were studied. The samples were analyzed for TgAb by the solid-phase radioassay developed in-house and compared with commercial anti-hTg IRMA kit (Immunotech, France). The control group comprised of 37 euthyroid males from our Centre. The intra- and inter-assay CVs for the two quality control samples (Control A = 104 ± 12.6 IU/mL and Control B = 1029 ± 114 IU/mL) were found less than or equal to 6.05 and 13.85 % respectively. Solid-phase radioassay showed a good agreement on comparison with Immunotech IRMA (r = 0.99). Using the proposed cut-off thresholds (in-house solid-phase radioassay 52 IU/mL and Immunotech IRMA 30 IU/mL), 5.4 % of the control subjects were positive for TgAb by both the methods. Prevalence of TgAb in DTC patients was 17.3 and 16.6 % using the Immunotech kit and in-house solid-phase radioassay respectively. The in-house solid-phase radioassay has the requisite sensitivity for the evaluation of TgAb comparable to commercial kit and also suitable for routine use as it is rapid, user friendly and economical. 相似文献
