A study of the development of contemporary monasteries in Taiwan

This study investigates the modernization of Buddhist Monasteries, as illustrated by three famous monasteries in Taiwan, Fo Guang Shan, Ten Directions Monastery, and Chung Tai Chan Temple. With these three case studies, on one hand we can compare them with traditional Buddhist architecture; on the other hand, we can also observe whether the space form and building style of Buddhist architecture had adjusted, transformed or even changed accordingly as a whole, while the Buddhist monasteries in Taiwan were, at that time, facing the modernization of Buddhism.

Microwells support high-resolution time-lapse imaging and development of preimplanted mouse embryos

A vital aspect affecting the success rate of in vitro fertilization is the culture environment of the embryo. However, what is not yet comprehensively understood is the affect the biochemical, physical, and genetic requirements have over the dynamic development of human or mouse preimplantation embryos. The conventional microdrop technique often cultures embryos in groups, which limits the investigation of the microenvironment of embryos. We report an open microwell platform, which enables micropipette manipulation and culture of embryos in defined sub-microliter volumes without valves. The fluidic environment of each microwell is secluded from others by layering oil on top, allowing for non-invasive, high-resolution time-lapse microscopy, and data collection from each individual embryo without confounding factors. We have successfully cultured mouse embryos from the two-cell stage to completely hatched blastocysts inside microwells with an 89% success rate (n = 64), which is comparable to the success rate of the contemporary practice. Development timings of mouse embryos that developed into blastocysts are statistically different to those of embryos that failed to form blastocysts (p–value < 10⁻¹⁰, two-tailed Student''s t-test) and are robust indicators of the competence of the embryo to form a blastocyst in vitro with 94% sensitivity and 100% specificity. Embryos at the cleavage- or blastocyst-stage following the normal development timings were selected and transferred to the uteri of surrogate female mice. Fifteen of twenty-two (68%) blastocysts and four of ten (40%) embryos successfully developed into normal baby mice following embryo transfer. This microwell platform, which supports the development of preimplanted embryos and is low-cost, easy to fabricate and operate, we believe, opens opportunities for a wide range of applications in reproductive medicine and cell biology.     

Am I a teacher? How educare givers in Taiwan construct their professional identity during socialisation into public preschools

A new job position, “educare giver,” which was created after kindergartens and preschools in Taiwan were integrated in 2012, has caused several problems such as ambiguity in the role of childcare givers and inequity in the division of labour. Studies have provided a limited scope and have not examined the identities and struggles of educare givers at the individual and organisational levels. This study investigated the effect of contextual factors on the professional identities of educare givers during their socialisation. The researchers adopted a qualitative research design and conducted in-depth interviews with 20 educare givers at public preschools. The findings reveal that educare giver identities are those as teachers, labourers, and teaching and administrative assistants. Contextual factors that affect the construction of their identities at the three stages of their socialisation are information channels, educational background, the recruitment process, titles, the attitudes of stakeholders, and job assignments.     

Global exponential robust stability of static interval neural networks with S-type distributed delays

The authors in [7] obtained the global asymptotical stability for static interval neural networks with S-type distributed delays by using the Razumikhin theorem. The aim of our paper is to investigate the global exponential robust stability by using the Lyapunov functional methods, and we will improve the proof methods more concise. A theorem and a corollary were obtained in which the boundedness, monotonicity and differentiability conditions on the activation functions are not required. So we generalize the results of related literature [7]. As an application, an example to demonstrate our results is given.     

Social Justice in Sport and Exercise Psychology: A Position Statement

ABSTRACT

There are varied approaches that have been used in sport for development (SFD) projects. This article is focused on the move by sport and exercise psychology researchers toward community-based SFD projects where marginalized groups are centralized. The authors have chosen two of their projects to exemplify different approaches to SFD. An initial project with an Aboriginal community is critically examined to reveal cultural missteps that perpetuated cultural colonization–something antithetical to community capacity building. The second project is then considered because of its closer alignment with cultural praxis and community capacity building. This second project focuses on the initial developments of a YMCA physical activity project designed to meet the needs of forced immigrants (a self-titled name developed by the refugee community members) and the staff who work with them. We culminate with five postulates proposed for SFD project teams derived from our vantage in sport and exercise psychology, where community engagement and eventual self-governance are imperatives.

教育创新的真谛——评谢庆的《诺贝尔摇篮幼稚园办学特色》

改革开放特别是上世纪90年代以来,教育创新引起了学术界和社会的普遍关注,成为国人耳熟能详的热门字眼.江泽民同志指出,创新是一个民族进步的灵魂,是一个国家兴旺发达不竭的动力,并对教育创新寄予厚望,将其与理论创新、制度创新、科技创新并列.胡锦涛同志强调,自主创新是掌握民族发展命运的关键之举;提高自主创新能力,建设创新型国家,是国家发展战略的核心,是提高综合国力的关键;要进一步推进科教兴国,就必须加强科技创新和教育创新.那么,究竟如何从理论到实践,从内容到方法,从规模到结构,从质量到效益等方面事半功倍地实施教育创新,并努力实现我们期待的创新效果呢?由湖南人民出版社2009年10月出版、谢庆所著的<诺贝尔摇篮幼稚园办学特色>一书以诺贝尔摇篮教育集团办学的理论与实践为我们探索了一条成功之路,提供了一个鲜活的范例,体现了教育创新的真谛.
