Covid-19: Emerging Considerations for Body Sourcing and Handling. A Perspective View from Nigeria     

Izuchukwu Azuka Okafor  Terkuma Chia 《Anatomical sciences education》2021,14(2):154-162

The current Coronavirus disease (Covid-19) pandemic has spread to about 220 countries of the world and has resulted in a significant number of deaths globally. Infections are still on the rise, and the impact on the global death rate could be devastating. There are fears over the likely impact of a large number of deaths on body sourcing and handling of cadavers for teaching and research. Historically, epidemics come with several challenges and have often led to some level of negligence of ethical practices and health and safety regulations associated with body sourcing and handling. The authors highlighted some emerging problems in this article, focusing on Africa and Nigeria in particular. These problems include a higher risk of coronavirus exposure for body handlers, shortage of cadavers for teaching and learning, a lack of standard regulations leading to unethical body sourcing and handling, and a lack of monitoring and collaboration needed for a well-coordinated Covid-19 pandemic response strategy. If these issues are ignored, the previous gains made in anatomical ethical practices may be destroyed. Some useful recommendations for policymaking geared toward prevention or curtailing these emerging issues have been instilled in this article.  相似文献   

Ready or Not: The Academic College Readiness of Southeast Asian Americans     

Chia S. Her 《Multicultural Perspectives》2014,16(1):35-42

The educational experiences of Southeast Asian Americans, particularly Cambodian Americans, Hmong Americans, Laotian Americans, and Vietnamese Americans, are characterized by numerous challenges, which can be attributed to their migration history, socioeconomic status, and English proficiency. By the end of 11th grade, a high percentage of Southeast Asian American students are not college ready. The educational challenges of Southeast Asian Americans have been overshadowed by the model minority stereotype. Educational policies targeting issues affecting the education of Southeast Asian Americans and teacher preparations that focus on getting Southeast Asian American students to be college ready could help change the educational story of this population.  相似文献   

Primary Children and Computer-Based Artwork: Their Learning Environment and Strategies     

Jane Chia  Birnie Duthie 《Asia Pacific Journal of Education》1994,14(2):42-48

This article summarises a research project with a group of twenty Singapore primary students who were introduced to computer graphics in an eight-week programme. Their actions and artwork were closely monitored by participant observers to see how they interacted with the computers and with each other as they learned how to use the tools and exercise judgement and control. Three aspects of behaviour which seemed to be particularly significant were: watching and internalising, providing a running commentary and pointing. The children's artwork showed that they could use the computer as a tool to create artwork and engage in high-level symbol-weaving.  相似文献   

Sensitive ages for physical fitness development     

Michael Chia 《山东体育科技》2007,29(2):79-80

Physical fitness testing in Singapore is mandatory from age 9 years old till 18 years old in schools. Time and effort are spent annually in training for these tests as schools are ranked according to the test results and pupil obesity rate. There are natural rhythms and tempos for the development of physical capabilities but these remain unexplained in the Singaporean context. Identification of these ＂sensitive time periods＂ for fitness development will help PE teachers be more realistic about young people＇ s physical fitness and allow for a more balanced approach in the conduct of PE in schools.  相似文献   

One-heater flow-through polymerase chain reaction device by heat pipes cooling     

Jyh Jian Chen  Ming Huei Liao  Kun Tze Li  Chia Ming Shen 《Biomicrofluidics》2015,9(1)

This study describes a novel microfluidic reactor capable of flow-through polymerase chain reactions (PCR). For one-heater PCR devices in previous studies, comprehensive simulations and experiments for the chip geometry and the heater arrangement were usually needed before the fabrication of the device. In order to improve the flexibility of the one-heater PCR device, two heat pipes with one fan are used to create the requisite temperature regions in our device. With the integration of one heater onto the chip, the high temperature required for the denaturation stage can be generated at the chip center. By arranging the heat pipes on the opposite sides of the chip, the low temperature needed for the annealing stage is easy to regulate. Numerical calculations and thermal measurements have shown that the temperature distribution in the five-temperature-region PCR chip would be suitable for DNA amplification. In order to ensure temperature uniformity at specific reaction regions, the Re of the sample flow is less than 1. When the microchannel width increases and then decreases gradually between the denaturation and annealing regions, the extension region located in the enlarged part of the channel can be observed numerically and experimentally. From the simulations, the residence time at the extension region with the enlarged channel is 4.25 times longer than that without an enlarged channel at a flow rate of 2 μl/min. The treated surfaces of the flow-through microchannel are characterized using the water contact angle, while the effects of the hydrophilicity of the treated polydimethylsiloxane (PDMS) microchannels on PCR efficiency are determined using gel electrophoresis. By increasing the hydrophilicity of the channel surface after immersing the PDMS substrates into Tween 20 (20%) or BSA (1 mg/ml) solutions, efficient amplifications of DNA segments were proved to occur in our chip device. To our knowledge, our group is the first to introduce heat pipes into the cooling module that has been designed for a PCR device. The unique architecture utilized in this flow-through PCR device is well applied to a low-cost PCR system.  相似文献   

Investigating the Development of the “Mobile Museum” from the Perspective of Service     

Chia‐Hui HUang  Fang‐Suey Lin 《Curator: The Museum Journal》2016,59(4):387-410

During economic development, modern museums face competition from various leisure activities and entertainment sites, and to achieve sustainable development, museums should reflect on providing high‐quality service to satisfy visitors’ expectations. Based on service design‐related theories, this research team conducted a case study to explore the planning, implementation, and meaning of Mobile Museums. It investigated design development from the perspective of public service design and summarized the policy, design, and service satisfaction results for Mobile Museums. Finally, the similarities in service processes are discussed between Mobile Museums and the general service industry. According to this study, attracting more visitors is the biggest issue facing museums today, as are the ways in which museums must actively provide service and become recognized to compete with others. This study identifies the onstage and backstage support of museums as well as their cultural features and non‐profit services.  相似文献

Putting the Case for the Case Study     

Jane Chia  Allan Walker 《Asia Pacific Journal of Education》1992,12(1):52-67

This paper sets out to review the on-going case study debate. We do not aim to enter the qualitative/quantitative discussion, nor do we suggest that the case study is the ultimate or only form of research. We suggest that case studies should be used in conjunction with other forms of research. What is important is that the techniques selected are appropriate for any proposed research undertaking so that quantitative and qualitative strategies can meaningfully co-exist within the same research project.

We do, however, suggest that in certain sectors the case study approach is misunderstood and under-utilized. The focus of the paper is an objective discussion of a number of issues which have been raised about the case study strategy. The discussion does not assume that there is ‘one type’ of case study, rather it refers to the multitude of case study approaches which can be classified under the case study label.

In addition to a review of the case study debate and some research strategies associated with the approach, the paper discusses a number of pertinent issues which continue to generate much debate. The issues of procedure, a multi-method strategy, objectivity, generalizability and presentation are reviewed in relation to case study research.

The case study approach has weaknesses, and its share of critics, but has become an established and respected form of research. Issues involved in case study research still need to be considered as it becomes more accepted as a viable and insightful form of research.  相似文献

A Cross-Cultural Validation of Perceived Locus of Causality Scale in Physical Education Context     

John C.K. Wang  Martin Hagger  Woon Chia Liu 《Research quarterly for exercise and sport》2013,84(2):313-325

We examined the validity of the factor structure and invariance of the Perceived Locus of Causality (PLOC) scale instrument scores across two nations endorsing collectivist (Singapore) and individualist (Great Britain) cultural values. Results indicated that confirmatory factor analytic models of the PLOC exhibited adequate ft according to multiple criteria within each sample and across samples. There was invariance in the item-intercepts across the two cultures. In addition, the simplex-like pattern of relations among the PLOC constructs was confirmed within cultures and in invariance analyses. Finally, latent factor means analysis revealed that the British participants tended to rate less self-determined forms of motivation lower than and more self-determined forms of motivation higher than the Singaporean participants.  相似文献
