Taking the English National Curriculum as its main example, this article argues that an overly nationalistic, normative and ‘fact-based’ citizenship education curriculum is failing to engage the dimensions of young people’s identities which they experience as deeply meaningful. There is thus a chasm – albeit a false one – between official discourses and pedagogies of citizenship and what young people consider to be their ‘real’ selves. I argue that citizenship education must develop a more sophisticated understanding of the complexities of how identities are formed and performed, especially in light of globalisation and increasing migration. I also make a somewhat unorthodox argument for conceptualising ‘relating-to-otherness’ in the same way that we think of music consumption. This has implications for how we experience, interpret, value and create ‘others’. The article also makes some recommendations for how these ideas can begin to be implemented in educational settings. 相似文献

The present study focused on the epistemology of teachers’ practical knowledge by addressing the following research question: how do teachers attempt to reason about their practices and their practical knowledge? The results indicated that teachers supported their practical knowledge claims using the “practical argument”. Within this conceptual framework, they relied on contextual grounds that call for the fact that something should or should not be “done”, rather than something is “true” or “false”. Contextual grounds, then, were found to be backed up by two significant types of warrants: moral ethos, and “what works” notion. Depending on what kind warrants they used, teachers’ practical knowledge was interpreted to be based on two different epistemic statuses: “practicable” knowledge and “praxial” knowledge. 相似文献

Action research is geared to changes for the better and has the potential to assist teachers to extend their teaching skills and develop a deeper understanding of themselves, their classroom and their learners. However, in the area of applied linguistics, the viability of action research has been seriously questioned. In this article, we argue that adopting a complexity‐theory perspective, which requires teachers to be dynamic and complex in their approach, helps in identifying action research as a suitable research tradition for investigating second‐language classrooms and in turn using it widely to invigorate the field of applied linguistics. Our argumentation is supported by the fundamental links between action research and complexity theory as an emerging paradigm in education. Although the case made in this article concerns second‐language classrooms, the conclusions reached may well apply to any classroom that shares some commonalities with second‐language classrooms. 相似文献

Cinnamon has been used as an anti-diabetic agent for centuries but only in recent few years its mechanism of action has been under investigation. Previous studies showed that cinnamon might exert its anti-diabetic effect via increasing glucose transporter isotype-4 (GLUT4) gene and glycoprotein contents in fat cells. To study if hydro-alcoholic cinnamon extract (HACE) enhances GLUT4 translocation from intracellular compartments of nuclear or endoplasmic reticulum membranes (N/ER) into the cytoplasmic membrane (CM). C2C12 myoblastic cell line were seeded in DMEM plus 20 % FBS and differentiated to myotubes using 2 % horse serum. After myotubes formation, 100 or 1,000 μg/ml HACE, as intervention, and as control 1 % DMSO were added for 3 h. Cells were washed and homogenized followed by ultracentrifuge fractionation, protein separation by SDS-PAGE and GLUT4 detection using semi-quantitative Western blotting. Data analysis was done by two-independent samples t test for comparison of mean ± SD of GLUT4 percent in categories. GLUT4 contents were higher in CM of groups 100 and 1,000 μg/ml HACE and lower in 1 % DMSO treated myotubes (CI = 0.95, P < 0.05). For N/ER reverse results were obtained (CI = 0.95, P < 0.05). As our results have shown HACE induces GLUT4 translocation from intra-cell into cell surface. We conclude that cinnamon maybe a choice of type-2 diabetes mellitus treatment because its extract enhances GLUT4 contents in CM where it facilitates glucose entrance into the cell. However it is necessary to trace the signaling pathways which are activated by HACE in muscular tissue. 相似文献

ABSTRACT This study was designated to investigate the kinematical differences between successful and faulty spikes, in order to identify the best strategies leading to better spike performance. Simulating a real-game condition, 13 elite youth attackers performed 6 spikes in the presence of 2 blocks. The kinematic variables of the spike performances were recorded using 6 optoelectronic cameras (Vicon Motion systems, Oxford, UK). The paired sample t-test was used to compare the kinematic variables recorded during the delivery of successful and faulty spikes. Among the successful trials, both the angular velocities of the knees (≈12.4%) and hips (≈13.3%), and the vertical velocity of the centre of mass at take-off (≈6.5%) and arm swing (≈8.2%) were considerably higher during the plant phase. Consequently, the jump (≈4.3%) and spike (≈1.5%) heights, as well as the wrist velocity (≈5.5%), were significantly higher during the jump phase of successful spikes. In successful spike performances, the attackers adopted higher hip and knee angular velocities, combined with efficient arm swings, to produce higher take-off velocities and reach higher jump heights. This approach provides them with the better position regarding the ball and the blockers to find the best path and hit the ball with higher arm velocities. 相似文献

In this study, we investigated the culture-invariant and culture-dependent nature of teachers’ ethical sensitivity in two countries. Our case study involves teachers from Finland (n = 864) representing Western culture, and from Iran (n = 556) representing Eastern culture. Culturally bound elements of ethical sensitivity were studied with the Ethical Sensitivity Scale Questionnaire. The analyses revealed that ‘Caring by connecting to others’ is a central, culturally invariant dimension of ethical sensitivity in both cultures. In the dimensions of ethical sensitivity, the dimension of ‘Taking the perspective of others’ is particularly dependent on culture, given the differences in the cultural dimensions of power distance and the collectivity of the countries studied. 相似文献

Colleagues helping each other to publish in medical sciences: Iranian field specialists' convenience editing strategies 
下载免费PDF全文
下载免费PDF全文 This article reports a study into 60 research articles (RAs) authored by Iranian medical researchers and published in high‐quality international English journals. It investigated how academic professionals in medical sciences implement peer convenience editing (CE) to improve articles and make them suitable for publication. The research identified nine editing interventions that were categorized as micro‐ or macro‐editing strategies. The findings indicated that the most frequently used strategies are micro‐strategies of substitution, addition, and mechanical alteration. The study also found that the abstract received the majority of editorial changes (mostly micro), followed by the introduction and then the discussion sections. The findings may help authors and institutions identify which sections and which types of editorial interventions are most likely to be required to ensure that RAs are optimized for publishing in international journals. 相似文献

In this paper two robust controllers for a multivariable vertical short take-off and landing (VSTOL) aircraft system are designed and compared. The aim of these controllers is to achieve robust stability margins and good performance in step response of the system. LQG/LTR method is a systematic design approach based on shaping and recovering open-loop singular values while mixed-sensitivity H∞ method is established by defining appropriate weighting functions to achieve good performance and robustness. Comparison of the two controllers show that LQG method requires rate feedback to increase damping of closed-loop system, while H∞ controller by only proper choose the weighting functions, meets the same performance for step response. Output robustness of both controllers is good but H∞ controller has poor input stability margin. The net controller order of H∞ is higher than the LQG/LTR method and the control effort of them is in the acceptable range. 相似文献
