危机与应对:新型冠状病毒肺炎疫情下的中国体育叙事

新型冠状病毒肺炎疫情(以下简称"疫情")下的体育叙事,不仅要阐发疫情期间体育事件及其社会意义,更应揭示不同体育要素在社会发展中的功能与作用,将对体育现实问题的思考转化为未来体育转型的应对策略。基于叙事的角度,以访谈的方式,探讨体育产业发展、东京奥运会延期、体育组织治理、奥运备战、居家体育、体育在线教学、体育中考等热点事件和话题。认为:①疫情对体育产业的影响呈现持续性、结构性、社会性等特征,在"转危为机"的话语下,应借助政府的积极行为,实现体育行业与体育产业的多层次融合,增强对消费端的刺激,提高体育企业的抗风险能力,最大程度地释放后疫情时代体育产业发展动力;②东京奥运会延期举办凸显国际奥委会内部治理的困境与危机,引发对中国体育赛事治理效能的思考,给奥运备战带来挑战,促使运动训练由传统化模式向集群化工业模式转变;③空间重叠与权力空间渗透造就居家体育的特殊"脱域"空间,成为"家庭-学校-社区"体育互动发展的催化剂,引发体育教学、社区体育、群众体育活动方式的改变,形成自觉行为更高的群众体育"在地化"驱动模式;④在疫情防控期间,体育话语在不同语境中的表达、转型与辩驳为体育话语转为文化资源提供契机,促进文化与体育的互动与整合,深刻影响人们的体育观念。

Virtual Microscopy as a Learning Tool in Brazilian Medical Education

Virtual microscopy (VM) is a widely used teaching method in Medical Education in many developed countries. In Brazil, however, this is not the case for most medical schools, considering Brazilian social inequality and uneven access to technology. Recently, the Covid-19 pandemic has also challenged Universities to seek and make a transition toward more effective methods of full-time online education. Thus, the main goal of this work was to verify student's perception and academic performance, assessed upon VM implementation in a Brazilian Medical School. Ribeirao Preto Medical School students answered a 26-question survey with regards to optical microscopy (OM) and VM. Academic performance was compared between participants that were (year of 2019) or were not (year of 2015) exposed to VM. Taken the results together, subjective impressions such as handling, suitability, learning effectiveness, and pleasure using the tools, have shown a higher score for virtual microscopy (median = 29), when compared to optical microscopy (median = 24) with a P-value < 0.001 by Wilcoxon rank test, upon measurement using an ordinal scale. Regarding academic performance, no statistically significant differences were found between groups (P-value = 0.38, Cohen's d = 0.19). Therefore, VM proved to be adequate to the Brazilian medical education in light of Brazilian social contexts and Covid-19 pandemic.     

The Potential Impact of COVID-19 on Student Learning and How Schools Can Respond

There is no denying the impact that the coronravirus disease (COVID-19) outbreak has had on many aspects of our lives. This article looks at the potential impact of COVID-19 on student learning as schools abruptly morphed into virtual learning environments using data from several instructional, practice, and assessment solutions offered by Renaissance. First, three hypothetical learning scenarios are considered using normative data from Star assessments to explore the potential impact on reading and math test performace. Next, data on Focus Skills are used to highlight which grades may have missed the most foundational math and reading content if instruction was stopped or reduced. Last, data from two of Renaissance's practice tools are used to evaluate whether students were practicing key skills following school closures. The article concludes that academic decline will likely occur but may be tempered by the increased use of practice tools; effects may look different for math and reading; and may impact grades and schools differently. As such, schools may need to leverage decision-making frameworks, such as the Multi-tiered Systems of Support/Response-to-Intervention (MTSS/RTI) framework, more than ever to identify needs and target instruction where it matters most when school begins in fall 2020.     

Strength,Weakness, Opportunity,Threat (SWOT) Analysis of the Adaptations to Anatomical Education in the United Kingdom and Republic of Ireland in Response to the Covid-19 Pandemic

The Covid-19 pandemic has driven the fastest changes to higher education across the globe, necessitated by social distancing measures preventing face-to-face teaching. This has led to an almost immediate switch to distance learning by higher education institutions. Anatomy faces some unique challenges. Intrinsically, anatomy is a three-dimensional subject that requires a sound understanding of the relationships between structures, often achieved by the study of human cadaveric material, models, and virtual resources. This study sought to identify the approaches taken in the United Kingdom and Republic of Ireland to deliver anatomical education through online means. Data were collected from 14 different universities in the United Kingdom and Republic of Ireland and compared adopting a thematic analysis approach. Once themes were generated, they were collectively brought together using a strength, weakness, opportunity, threat (SWOT) analysis. Key themes included the opportunity to develop new online resources and the chance to engage in new academic collaborations. Academics frequently mentioned the challenge that time constrains could place on the quality and effectiveness of these resources; especially as in many cases the aim of these resources was to compensate for a lack of exposure to cadaveric exposure. Comparisons of the actions taken by multiple higher education institutions reveal the ways that academics have tried to balance this demand. Discussions will facilitate decisions being made by higher education institutions regarding adapting the curriculum and assessment methods in anatomy.     

20世纪30年代粤港走私问题探析

20世纪30年代，基于政治、地理及经济等因素，加之世界经济危机风暴的冲击，粤港两地走私现象日趋猖獗。这不但严重影响了粤港间的正常贸易活动，也造成国货滞销，进而在一定程度上抑制了国内经济的发展。     

HBME-1、CK19基因在甲状腺结节的表达状态及诊断价值

目的：研究分析HBME-1、CK19基因在甲状腺结节的表达状态及诊断价值。方法：回顾性分析天津肿瘤医院头颈外科1975．1～1998．1月收治的初治甲状腺乳头状癌行甲状腺癌联合根治术的有完整随访资料的93例患者临床、组织病理和免疫组织化学染色资料，与同期收治的15例结节性甲状腺肿、16例甲状腺腺瘤相比较。对常规HE染色证实上述病变的蜡块分别行HBME-1和CK19免疫组织化学染色。结果：93例甲状腺乳头状癌病例中，HBME-1基因阳性表达甲状腺乳头状癌为51例（54．8％），甲状腺良性病变为5例（16．1％）；CK19基因阳性表达甲状腺乳头状癌为39例（41．9％），甲状腺良性病变为4例（12．9％）。两种基因在甲状腺乳头状癌和良性病变中的阳性表达均存在统计学差异。HBME-1、CK19基因表达与甲状腺乳头状癌患者的性别、年龄、肿瘤大小、局部侵犯、颈淋巴结转移无明显相关性。结论：HBME-1、CK19基因在甲状腺乳头状癌中表达增强，在甲状腺结节的鉴别诊断中是有用的辅助手段。CK19在区分甲状腺乳头状癌和乳头状增生中是一个很好的标志物。
