In this article, we discuss communication between early educators speaking their native language and parents who speak English as a second language. Parents who may have a limited proficiency in the second language face challenges to understanding semantic and pragmatic aspects of English. Actual early childhood conference talk in which parents were speaking English as a second language will illustrate potential difficulties to listening comprehension and communication. Additionally, semantics and pragmatics will be used as a framework for recommending strategies to facilitate these parents?? ability to comprehend and communicate during discussions with early educators.  相似文献

Intervention at scale with the aim of improving student participation, engagement and outcomes in mathematics education is a challenge for educational policy makers and reformers. This article argues that an iterative annual cycle of policy formulation, implementation and evaluation enabled ongoing adjustments to the strategic focus, the professional development model and the system infrastructure as the New Zealand Numeracy Development Project was taken to scale. The analysis draws on the project’s evaluation data over a 6-year period to demonstrate how adjustments were made over time to the pedagogical tools and to the professional development processes. The ongoing development of knowledge supported the management of strategic risks in taking the project to scale: the ongoing appropriation of adequate levels of resourcing to support the school-based professional development model and the availability of system-wide expertise for effective implementation. The analysis suggests that conceptualising implementation as an interdependent and interrelated component of an iterative policy process and as an opportunity for knowledge building ensured a continuing focus on student outcomes. The dynamic approach to the policy process appeared central to building this intervention’s effectiveness and feasibility at scale.  相似文献

Objective

The aim of this study was to evaluate the concentrations of C-reactive protein (CRP), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and the degree of homeostasis model assessment-insulin resistance (HOMA-IR) in patients with morbid obesity exposed to a three-week low-calorie diet and balneotherapy.

Methods

The study included 33 patients (25 females and 8 males; mean age 46 years) with body mass index (BMI) values of >40 kg/m2. Evaluations of CRP, IL-6, TNF-α, lipid profile, HOMA-IR, and fasting glucose were carried out before (baseline data) and three weeks after the treatment. The control group consisted of 20 healthy volunteers (15 females and 5 males) with a mean age of 39 years and BMI values of ≤24.9 kg/m2.

Results

In the blood of patients with morbid obesity we found significantly elevated levels of CRP, TNF-α, triglycerides, HOMA-IR and fasting glucose, but a decreased level of high density lipoprotein (HDL)-cholesterol, compared with the healthy individuals. The treatment resulted in about a 9.4% reduction in body weight from 122.5 to 111.0 kg and a significant decrease in the concentration of CRP, but no change in TNF-α or IL-6. HOMA-IR was significantly reduced.

Conclusion

The decrease in CRP level without changes in TNF-α or IL-6 concentrations after the low-calorie diet and balneological treatment, suggests that an essential amount of adipose tissue must be removed before proper adipocyte function is restored. The decrease in HOMA-IR indicates an improvement in insulin sensitivity, which is beneficial in obese patients.

Objective  

The influence of hormone replacement therapy (HRT) on hemostasis processes depends on the type of hormone, the combination of doses, the time of taking HRT, and the route of administration (oral, transdermal, implanted). The aim of the current study was to assess some parameters of coagulation, especially tissue factor pathway inhibitor (TFPI) and tissue factor (TF) in postmenopausal women using oral or transdermal HRT.  相似文献

INTRODUCTION Scalable video coding (SVC) (Schwarz et al., 2004) is the most promising video format for appli- cations of collaborative communication. First, SVC format, which is extended from the latest advanced video coding (AVC), is appropriate for creating a wide variety of bitrates with high compression effi- ciency. Second, an original SVC bitstream can be easily truncated in different ways to meet various characteristics and variations of devices and connec- tions. The scalabil…  相似文献

In this paper, a semantic categorization method in generic home photos is proposed. In recent years, the semantic categorization of image has been a challenge due to the proliferation of digital home photos. Our approach is to detect semantically meaningful concepts contained in a photo. The proposed method incorporates an intermediate level of concepts, called local concept, so that it catches well semantic meaning of local regions of image as bridging the semantic gap of the low-level features and high-level category concepts. To detect the local concepts from the home photo, region segmentation by photographic region template and concept merging is also proposed. The efficacy of the proposed semantic categorization method was demonstrated with 3828 general home photos. The experiment results showed the proposed categorization method would be useful to detect multiple semantic meaning of the home photos.  相似文献

This study investigated four novice secondary teachers’ experience and perceptions of teacher education in relation to their current work experience in a high-stakes testing context. The novice teachers commonly indicated that their preparation, which had focused on content expertise, turned out to have little significance in schools, as they mainly executed teaching to the test. Instead, their role as homeroom teachers, which was concerned with caring and supporting students, was found to have much more significance. Accordingly, they indicated that teacher education must more strongly emphasise preparing teachers for that role, which requires them to become mature, considerate, and autonomous educators. Based on this finding, this study suggests the need for a clearer conception of and emphasis on the subjectification function of teacher education that is grounded in the consideration of the fundamental vision, purpose, and meaning of teacher education in a society.  相似文献
