This paper aims to identify key issues involved in MEd final project supervision and to highlight the potential of supervision from an academic institution to change educational reality through the postgraduate student-teachers’ work-based final project as insider researchers in Israeli schools. It draws on analysis of case-study data from two supervision workshops for student-teachers (Although most students studying for MEd degrees in Israel are teachers or even principals with years of experience of teaching and sometimes management they will be referred to in this paper as student-teachers for uniformity and clarity.) in a master’s degree programme in Educational Leadership. It focuses on data generated from interviews with three supervisees. The paper’s findings highlight the supervision process, indicating stages of this process that assist students to develop their research skills in order to change school reality in different scopes and dimensions and to adopt inquiry as a stance. The student-teachers identify difficulties in schools and motivate and help to implement educational change. In short, the paper provides a model that can potentially enrich practice in the field with knowledge generated by academic research and bridge the gap between theory and practice.  相似文献

OBJECTIVES: This cross-sectional survey was conducted to evaluate the awareness and actual professional experience of pediatricians in Kuwait regarding child maltreatment, a topic rarely explored in this part of the world. METHODS: Data were obtained from all pediatricians in public hospitals with pediatric emergency services using a structured detailed self-completed questionnaire. RESULTS: The experience of child neglect was more common than that of child abuse in the clinical practice of surveyed pediatricians. Fifty percent of 117 pediatricians (69% of all eligible) reported having encountered at least 1 case of abuse and up to 3 cases of neglect in the past year. Women and younger doctors more commonly recognized hypothetical situations as maltreatment, and believed child abuse and neglect as being common or very common in Kuwait. Other demographic or professional variables did not affect recognition of maltreatment. Participants would most likely alert social workers about suspected maltreatment cases. More than 80% did not know whether there is a legal obligation to report or which legal authorities should receive reports of suspected cases. DISCUSSION AND CONCLUSIONS: National ethical guidelines regarding reporting suspected cases of maltreatment must be established. Laws protecting maltreated children and reporting physicians must be immediately enacted. Additional training is required to help pediatricians, especially expatriates from other cultures, to diagnose with certainty cases of child maltreatment in their practice in Kuwait.  相似文献

Isolation of new bacterial strains and recognition of their metabolic activities are highly desirable for sustainability of natural ecosystems. Biodegradation of dimethyl phthalate (DMP) under anoxic conditions has been shown to occur as a series of sequential steps using strain CW-1 isolated from digested sludge of Sibao Wastewater Treatment Plant in Hangzhou,China. The microbial colony on LB medium was yellowish,3~5 mm in diameter,convex in the center,and embedded in mucous externally. The individual cells of strain CW-1 are irregular rods,measuring (0.6~0.7)×(0.9~1.0) μm,V-shaped,with clubbed ends,Gram positive and without any filaments. 16S rDNA (1438 bp) sequence analysis showed that the strain was related to Arthrobacter sp. CW-1 and can degrade PAEs utilizing nitrate as electron acceptor,but cannot mineralize DMP completely. The degradation pathway was recommended as: dimethyl phthalate (DMP)→monomethyl phthalate (MMP)→phthalic acid (PA). DMP biodeg-radation was a first order reaction with degradation rate constant of 0.3033 d-1 and half-life 2.25 d. The DMP conversion to PA by CW-1 could be described by using sequential kinetic model.  相似文献

This paper discusses the decision of Muslim female principals in Israel to don the hijab following their appointment to school principalship. This research employed narrative life-story interviews to understand the women's decision to alter their appearance and how this transition is connected to their role as female school principals in the indigenous Muslim community in Israel and the reaction they faced both in personal and professional spheres. The principals' narratives elucidate that transition to wearing the hijab was a matter of choice and collective belonging; it empowers them and affected their leadership style, although it also provokes others' resistance and reactions. Findings clarify the social and personal identity of Arab Muslim women school principals in Israel, and point to the need for consideration of traditional cultural contexts, to enrich managerial theory. This understanding also supports the argument that governmental and organizational policies and initiatives should recognize the diversity in Muslim women's backgrounds and the dangers of privileging mainstream women's perspectives.  相似文献

The provision of banking services on the Internet (e-banking) is growing but there is a lack of research related to the organisational issues involved in its adoption. This paper brings theory and practice together by synthesising the existing literature with real-life experience of a UK bank. Two questions motivated this research. First, what is the experience of organisations in adopting e-banking? Second, what are the organisational factors which are critical to the success in e-banking adoption? A case study research approach was used to investigate organisational critical success factors in e-banking adoption at The Woolwich bank. The factors found to be most critical for success in e-banking included: understanding customers, organisational flexibility, availability of resources, systems security, established brand name, having multiple integrated channels, e-channel specific marketing, systems integration, systematic change management, support from top management, and good customer services. We concluded that banks need to implement considerable organisational changes in order to web-enable themselves. The main focus of their e-commerce strategy should be to integrate the e-banking channel with other service delivery channels to maximise benefits.  相似文献

Sewage sludge composting is an important environmental measure. The reduction of nitrogen loss is a critical aim of compost maturation, and the addition of spent mushrooms (SMs) and herbal residues (HRs) may be helpful. To evaluate the nitrogen transformations during co-composting of sewage sludge, SMs, and HRs, windrows were constructed in a residual processing plant. Dewatered sewage sludge and sawdust were mixed with SMs and HRs at two proportions on a fresh weight basis, 3:1:1 (sewage sludge:sawdust:SMs or HRs) and 3:1:2 (sewage sludge:sawdust:SMs or HRs). The mixture was then composted for 40 d. Changes in the physicochemical characteristic of sewage sludge during composting were recorded and analyzed. Addition of SMs and HRs accelerated the temperature rise, mediating a quicker composting maturation time compared to control. The addition also resulted in lower nitrogen losses and higher nitrate nitrogen levels in the compost products. Among the windrows, SM and HR addition improved the nitrogen status. The total nitrogen (TN) and nitrogen losses for SM and HR treatments ranged from 22.45 to 24.99 g/kg and from 10.2% to 22.4% over the control values (18.66–21.57 g/kg and 40.5%–64.2%, respectively). The pile with the highest proportion of SMs (3:1:2 (sewage sludge:sawdust:SMs)) had the highest TN level and the lowest nitrogen loss. The germination index (GI) values for all samples at maturity were above 80%, demonstrating optimal maturity. The addition of SMs and HRs augments sewage composting.  相似文献

Individuals seek information for informed decision-making, and they consult a variety of information sources nowadays. However, studies show that information from multiple sources can lead to information overload, which then creates negative psychological and behavioral responses. Drawing on the Stimulus-Organism-Response (S-O-R) framework, we propose a model to understand the effect of information seeking, information sources, and information overload (Stimuli) on information anxiety (psychological organism), and consequent behavioral response, information avoidance during the global health crisis (COVID-19). The proposed model was tested using partial least square structural equation modeling (PLS-SEM) for which data were collected from 321 Finnish adults using an online survey. People found to seek information from traditional sources such as mass media, print media, and online sources such as official websites and websites of newspapers and forums. Social media and personal networks were not the preferred sources. On the other hand, among different information sources, social media exposure has a significant relationship with information overload as well as information anxiety. Besides, information overload also predicted information anxiety, which further resulted in information avoidance.  相似文献

Purpose: This study identifies perceptions of faculty about the current level of information literacy (IL) skills of engineering students in higher education in Pakistan. It may help to design better IL programs for the tertiary level students. Methodology: The study used ACRL Information Literacy Competency Standards for Science and Engineering/Technology as the basis to assess these perceptions. Teachers of the National University of Science & Technology (NUST), who were teaching engineering students of postgraduate level, were selected as population. A structured questionnaire was sent to 113 faculty members and the response remained 80 percent. Paired samples t-test was used for data analysis through Statistical Package for Social Sciences (SPSS). Findings: Research indicates that faculty perceived IL skills of their PhD level students higher than those of MS level students. Originality: The term “Information literacy” is yet new on the Pakistani library scene. Regarding perceptions of faculty about information literacy skills of their students so far no study has been carried out in Pakistan. This study will help to identify existing IL skills of Pakistani students of university level, their requirements and how these requirements can be best fulfilled.  相似文献
