The purpose of this investigation was to gain an understanding of the challenges of teaching non‐speaking learners with intellectual disabilities and the scope of augmentative and alternative communication (AAC) used in primary school settings in Gaborone, Botswana. A qualitative interview methodology was used to investigate the experiences of 11 special educators working with non‐speaking learners with intellectual disabilities. Participants of the study revealed that teaching non‐speaking students with intellectual disabilities is challenging. The study further showed that AAC systems were not widely used in Botswana, and that teachers lacked knowledge and skills. Nevertheless, the participants recognised the importance of AAC in enhancing the functional communication skills of the non‐speaking learners with intellectual disabilities. Based on the findings recommendations are made to pave the way forward.  相似文献

Usually sickle cell traits are asymptomatic but co-existence of various factrors may alter the clinical as well as biochemical levels. In India sickle cell traits are neglected condition. Here we are presenting the alpha deletion in association with low serum iron and increased HbF level with Xmn-1 carriers in sickle cell traits. Sickle traits with alpha deletions had significantly low level of serum iron (P-value <0.05) with low level of reticulocytes and red cell indices while Xmn-1 polymorphism associated with increased HbF level. Study concludes low serum iron associated with alpha deletions and high level of HbF associated with Xmn-1 polymorphism in sickle cell traits.  相似文献

Splitting of comets is a very interesting celestial phenomenon. If we look back we find that a number of famous comets have disintegrated and the broken-up fragments are either lost forever or have survived as separate pieces. In this article, the mechanism of cometary splitting and a brief history of their fragmentation have been discussed.  相似文献

ABSTRACT

This study explored the impact of a living-and-learning program (LLP) in a residential college of an Asian university on a freshmen cohort. It utilized a theoretical framework based on Astin’s input-intermediate outcome-environment-outcome model. We examined survey data collected at two time points a year apart to understand how the freshmen’s learning outcomes were influenced by their pre-college intentions and beliefs, their involvement and leadership in the LLP, and the LLP’s environment. We found that pre-college perceived self-confidence had no impact on the learning outcomes. However, pre-college perceived competence in personal and intellectual growth was a significant contributing factor for involvement and post-college self-confidence. The freshmen’s involvement in turn positively predicted their personal and intellectual growth and post-college self-confidence. The academic aspects of the LLP’s environment also contributed to this growth. The findings have ramifications for the design of LLPs, in particular, the definition and measurement of learning outcomes, the criteria for admissions, and the facilitation of student involvement.  相似文献

This article examines the negotiation of organizational tensions by purpose-driven consultancies, for-profit firms also motivated by social change agendas in their implementation of organizational development for corporate clients. Using two case studies – APCom training ethical corporate leaders, and GreenD communicating environmental sustainability programs – we trace how such consultancies negotiate these tensions, and how their underlying purpose might accordingly transform. Our multi-case study suggests two broad tensions related to purpose and impact that are experienced in context-specific ways by the consultancies. Although members sought to frame these tensions in positive ways, as complementary dialectics or contradicting the dominant capitalist system, they were also at risk of devolving into more paradoxical contradictions and even debilitating double binds, without sustained discussion to ‘repurpose’ the firms. We close by discussing theoretical and practical implications for purpose-driven consultancies, given that their pursuit of social change is often at odds with the status quo.  相似文献

ABSTRACT

The curriculum, Hot Wheels Speedometry (Mattel, El Segundo, CA, USA), was designed to align with the Next Generation Science Standards for science and the Common Core State Standards for mathematics. Our objective was to develop, implement, and evaluate the impact of this integrated science, technology, engineering, and mathematics (STEM) curriculum on students' knowledge, interest, and engagement. The authors conducted the study in a district where students were predominantly from communities under-represented in STEM fields. The findings indicate that student individual interest developed. Furthermore, students demonstrated affective, behavioral, and cognitive engagement along their progression of interest development. The study shows promise for the development of interest and engagement in under-represented groups through the use of an integrated STEM curriculum.  相似文献

Teachers’ engagement in professional learning is vital to the profession’s sustainability. Their professional learning is influenced by the demands of balancing work, family, and the strain of balancing the two. This challenge is addressed through the notion resilience, operationalized as career adaptability. In a sample of teachers (= 193), the present research explored the relations between career adaptability, family-to-work conflict (time-based and strain-based), and engagement in professional learning. Structural equation modelling revealed that time-based conflict mediated the relation between career adaptability and strain-based conflict. Strain-based conflict, in turn, negatively predicted engagement with professional development studies. It is recommended that strategies for teachers’ professional learning are inclusive of contextual factors, such as family-to-work conflict, and focused on enhancing their career adaptability.  相似文献

Recall from Resonance, Vol. 1, No. 7 that when the Drunkard asks: “Will I ever, ever get home again?”, Polya answers: “You can’t miss, just keep going and stay out of 3D!” In this two-part article we show how to look at this question of recurrence and transience of random walks (which was originally asked and solved by George Polya) through electrical networks. In the first part we look at the related electrical networks.  相似文献

This study was carried out to see the effect of the aqueous extract ofOcitum sanctum Linn (Tulsi) with Vitamin E on biochemical parameters and retinopathy in the streptozotocin-induced diabetic albino male rats. Adult albino male rats weighing 150–200 gm were made diabetic by intraperitoneal injection of streptozotocin in the dose 60 mg/kg in citrate buffer (pH 6.3). The diabetic animals were left for one month to develop retinopathy. Biochemical parameters like plasma glucose, oral glucose tolerance and glycosylated hemoglobin HbA1c, were measured along with lipid profile, and enzymes like glutathione peroxidase (GPX), lipid peroxidase (LPO), superoxide dismutase (SOD), catalase (CAT) and glutathione-S-transferase (GST) in normal, untreated diabetic rats and diabetic rats treated withOcimum sanctum L extracts and vitamin E. Fluorescein angiography test was done for assessing retinopathy. Results on biochemical parameters were analyzed statistically by using ANOVA followed by Dunnet's ‘t’-test. A p-value of <0.05 was considered as significant. Evaluation of biochemical profile in treated groups showed statistically significant reduction in plasma levels of glucose, HbA1c, lipid profile and LPO, and elevation of GPX, SOD, CAT and GST. Treatment of the diabetic animals withOcimum sanctum and Vitamin E, alone and in combination for 16 weeks showed reversal of most of the parameters studied including plasma glucose levels. Angiography showed improvement in retinal changes following combined antidiabetic treatment.  相似文献
