School systems are a major social change agent capable of challenging social inequalities and economic disadvantages. Yet, while schools in Australia are being confronted with increasingly culturally diverse populations as well as an increasing focus on student retention, this transformative role is increasingly being played out in a broader educational context that has been found to replicate rather than challenge patterns of social inequality. Successive governments in Australia have responded to this context with a raft of policy initiatives. This paper, based on three‐year longitudinal research undertaken in the city of Melbourne, outlines this policy context and introduces the theoretical approach that underpins its innovative approach to managing cultural diversity in educational institutions. It argues for, and presents, a multidimensional model for managing cultural diversity in schools, one that provides the tools for transformative practices to be undertaken to effect positive change in school environments for the benefit of all students. 相似文献

In the present study, paclitaxel was archaeosomed to reduce side effects and improve its therapeutic index. Carriers have made a big evolution in treatment of many diseases in recent years. Lipid carriers are of special importance among carriers. Archaeosome is one of the lipid carriers. Paclitaxel is one of the drugs used to treat breast cancer which has some unwanted side effects despite its therapeutic effects. Archaeosomes were extracted from methanogenic archi bacteria and synthesized with a certain ratio of paclitaxel in PBS. The mean diameter of archaeosomal paclitaxel was measured by Zeta sizer instrument, Drug releasing of archaeosomal paclitaxel was examined within 26 h which results showed that the most drug releasing occurs during first 3 h. The cytotoxicity effect of archaeosomal paclitaxel on breast cancer’s cell line was evaluated by MTT assay which results showed that the cytotoxicity effect of archaeosomal paclitaxel on breast cancer’s cell line is more than that of the standard paclitaxel formulation. The results indicated that new drug delivery of paclitaxel using archaeosome, increases the therapeutic index of the drug. 相似文献

Measurement and control of pressure-driven flow (PDF) has a great potential to enhance the performance of chemical and biological experiments in Lab on a Chip technology. In this paper, we present an optofluidic flow sensor for real-time measurement and control of PDF. The optofluidic flow sensor consists of an on-chip micro Venturi and two optical Fabry-Pérot (FP) interferometers. Flow rate was measured from the fringe shift of FP interferometers resulted from movement fluid in the on-chip micro Venturi. The experimental results show that the optofluidic flow sensor has a minimum detectable flow change of 5 nl/min that is suitable for real time monitoring and control of fluids in many chemical and biological experiments. A Finite Element Method is used to solve the three dimensional (3D) Navier–Stokes and continuity equations to validate the experimental results. 相似文献

ABSTRACT Ongoing global issues relating to the decline of the popularity of institutional religions, the rise of numbers of non-religious persons, and new models of spirituality in superdiverse societies have resulted in the need to reconceptualise religious diversity as worldviews diversity, and to critically examine increasing calls for the provision of worldviews education in schools. This paper first examines the key concepts of superdiversity and religious complexity in contemporary societies. It then presents an overview of scholarship pertaining to the concepts of worldviews and worldviews education. It next provides case studies of worldview/s education in Finland and Australia, drawing on data of recently completed qualitative and quantitative studies in the two countries. Finally, it concludes with a comparative analysis of the two contexts, and recommendations pertaining to worldviews education as a means of enhancing cross-cultural literacy, positive attitudes to religious diversity and thereby social inclusion. 相似文献

In most developing countries, as the young population increase in number and consequently, the demands for higher education rise, the governments cannot respond to all demands. Accordingly, they develop private higher education sectors as an alternative solution. In developed countries, some moving factors are influential in creation and the increase of private institutions but there are scarce evidences and comparative results about developing countries. The current comparative study seeks to investigate and analyze the main factors of privatization in higher education of three developing countries: Indonesia, Malaysia, and Kenya. After a short outline of theoretical foundations, this study provides more in-depth explanations of the principal and common effective factors. 相似文献

Competence and sensitivity at intercultural communication are essential for an effective and appropriate communication in the context of health care. The present study sought to survey the levels of intercultural communicative competence (ICC) and intercultural sensitivity (IS) of 400 Iranian medical students based on their ethnic backgrounds (i.e. Fars, Turkish, Kurdish, and Lor). The findings of this study indicated that the four ethnic groups had moderate levels of ICC and IS, and that the Lor ethnic group had the lowest mean scores on the four dimensions of ICC (i.e. knowledge, attitude, skills, and awareness). Implications and suggestions for further research are discussed. 相似文献

This study deals with the stability analysis of a flexible structure with one and only one boundary control. The system is composed of three parts: a cart (motorized platform), a flexible cable, and a load mass attached to the lower part of the cable. This situation leads to a hybrid system as a mathematical model for the cable dynamics: one partial differential equation coupled to two ordinary differential equations. Despite the presence of a time-delay in the top-end of the cable, we are able to prove that the hybrid system is well-posed in the sense of semigroups theory and more importantly, only one boundary control can guarantee the exponentially decay of the energy of the system under reasonable conditions on the parameters of the system. This outcome considerably improves the result recently established in [17], where two more controls are required: one interior (Kelvin–Voigt) damping which acts over the entire cable and another boundary control which is exerted on the lower-end of the cable. Furthermore, we provide an estimate of the exponential decay of the system by means an appropriate Lyapunov functional. Lastly, numerical examples are presented in order to ascertain and highlight our theoretical outcomes. 相似文献
