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   

Bilingual education through a pluri-centric approach: A case study of the effects of simultaneously learning two languages on L1 and L2 reading and writing proficiency     

《Studies in Educational Evaluation》2020

Language education has often been conducted based on monoglossic ideologies that keep L1 and L2 separate, a practice that receives growing criticism as out of sync with today’s multilingual globalized world. Informed by interdependence hypotheses and translanguaging theory, this research study explored the effects of a pluri-centric approach to learning L1 and L2 simultaneously. Through a bilingual intervention course with data collected from interviews, parents’ logbooks, observation field notes, questionnaires, and L1 and L2 reading and writing tests, this case study (n = 9) revealed that the approach effectively improved learners’ L1 and L2 proficiency, learning behaviour outside the classroom, self-efficacy, and confidence. Overall, the participants also perceived the bilingual course as effective, efficient, and innovative. The study provides a basis to reflect upon transferrable skills and core underlying proficiency as powerful concepts to draw upon in enhancing bilingual proficiency and effecting positive changes in learners’ behaviour and psychological well-being.  相似文献

王晓红  张奔 《科研管理》2018,39(2):135-142

本文利用2007-2014年我国88所高校的面板数据，采用系统广义矩（Sys-GMM）模型方法，实证研究了校企合作活动对我国高校科研绩效的影响，以及高校类型的调节作用。研究结果表明：（1）校企合作对高校科研绩效的影响呈倒U型；（2）高校类型对校企合作与高校科研绩效之间的倒U型曲线关系具有显著的负向调节作用。本研究不仅丰富了产学研合作理论，同时对高校制定及完善校企合作政策提供了理论参考。  相似文献   

School readiness of maltreated children: Associations of timing,type, and chronicity of maltreatment     

《Child abuse & neglect》2018

Children who have been maltreated during early childhood may experience a difficult transition into fulltime schooling, due to maladaptive development of the skills and abilities that are important for positive school adaptation. An understanding of how different dimensions of maltreatment relate to children’s school readiness is important for informing appropriate supports for maltreated children. In this study, the Australian Early Development Census scores of 19,203 children were linked to information on child maltreatment allegations (substantiated and unsubstantiated), including the type of alleged maltreatment, the timing of the allegation (infancy-toddlerhood or preschool), and the total number of allegations (chronicity). Children with a maltreatment allegation had increased odds of poor school readiness in cognitive and non-cognitive domains. Substantiated maltreatment was associated with poor social and emotional development in children, regardless of maltreatment type, timing, or chronicity. For children with unsubstantiated maltreatment allegations, developmental outcomes according to the type of alleged maltreatment were more heterogeneous; however, these children were also at risk of poor school readiness irrespective of the timing and/or chronicity of the alleged maltreatment. The findings suggest that all children with maltreatment allegations are at risk for poor school readiness; hence, these children may need additional support to increase the chance of a successful school transition. Interventions should commence prior to the start of school to mitigate early developmental difficulties that children with a history of maltreatment allegations may be experiencing, with the aim of reducing the incidence of continuing difficulties in the first year of school and beyond.  相似文献   

基于局域核心择优模型的B2B电商网络仿真研究     

李应  黄康  杨璇  武文颖 《科技管理研究》2019,39(18)

通过运用复杂网络对B2B电商网络进行建模仿真,发现B2B网络的运行规律,提出减少平台风险的措施。首先分析B2B电商网络的特征和演化动因,提出网络演化的动态规则、局域择优连接规则和自演化规则。接着基于演化规则,在BA模型的基础上,构建更契合于B2B电商网络的局域世界核心择优连接(Local world Core Preferred connection)演化模型。最后,采用NetLogo软件对LCP演化模型进行仿真实验。结果验证B2B电商网络具有无标度性,发现网络具有小世界性；以及网络对随机干扰具有较强的鲁棒性。  相似文献

詹鸣燕  冯娜 《唐山学院学报》2018,31(1):17-21

北京政变后,中国共产党确定了同国民军等有进步倾向的军队建立统一战线的方针。在贯彻这一方针的过程中,李大钊及其领导的中共北方区委把胡景翼统治下的河南作为工作的重点。20世纪20年代,李大钊曾两次亲临开封,在国民二军中积极开展统一战线工作,为促进国民革命统一战线在河南的形成及巩固作出了重大贡献。  相似文献   

高强度的环境规制能够促进国内大气科技创新吗？——以〖SO〗_2排放控制技术为例          下载免费PDF全文

林玲  赵子健  曹聪丽 《科研管理》2018,39(12):45-52

从理论上来说，波特弱假说涉及双重外部性问题，即大气污染的负外部性和技术创新的正外部性，环境规制和知识产权保护合力才能予以切实彻底解决，而后者并没有得到普遍重视。本文认为，波特弱假说需要考虑知识产权保护强度。以SO_2排放控制技术为例，本文运采用2000-2013年省际省份面板数据，结合固定效应模型进行实证研究检验了知识产权保护对于波特弱假说的作用。结果发现，当知识产权保护较弱时，环境规制对大气科技创新具有呈现负向影响；。只有当知识产权保护较强时力度超过一定阈值时，环境规制才会对大气科技创新产生正向影响，波特弱假说成立。此外，环境规制和知识产权保护影响大气科技创新的交叉效应主要出现在企业，而非科研院所和个人，创新主体存在明显的差异性。  相似文献
