对深化上海体育科学研究所科技体制改革的几点设想──上海体育科学研究所现状与出路分析

上海体育科学研究所（下称体科所）曾经为体育事业做出过贡献。在新的历史条件下体科所的进一步发展遇到了较大的困难。体制改革滞后是产生困难的深层次的原因。上海体育科技体制改革遇到了良好的机遇。抓住机遇，加大体科所科技体制改革力度，在经费运作、领导体制、组织机构、用工机制等方面作一番较为彻底的改变，是体科所保持可持续发展，开创新局面的出路所在。理顺体制；实现“科技兴体”，也是体科所对跨入新世纪的上海体育发展的一项历史责任。     

略述唐代营州的经济

营州是唐王朝在东北地区的重镇,是东北地区的政治、军事、经济中心.营州农业发展并不落后,先进生产工具的使用,促进了营州农业的深耕细作,扩大了耕地面积,促进了营州农业的发展.营州地区多民族杂居生活,畜牧业比较发达,尤以养马业最为兴盛.营州的手工业以制陶业为主.唐代营州商业发展很快,商品经济在社会经济生活中占有相当重要的地位,营州与西方国家有着频繁的贸易往来.唐王朝发展经济的政策和营州重要的地理位置客观上推动了营州经济的发展.朝阳地区出土的唐代文物,为我们研究营州经济提供了丰富的实物资料.

Circulating Biomarkers and their Possible Role in Pathogenesis of Chronic Hepatitis B and C Viral Infections

The present study evaluated the plausible role of circulating biomarkers in immune pathogenesis of chronic hepatitis considered a priority in clinical hepatology. Total viral load of chronic hepatitis B virus (HBV) and hepatitis C virus (HCV) patients was quantified and correlation studies were performed with circulating levels of Th1/Th2 cytokines; C reactive protein and circulating nucleosomes; glutathione reductase (GR) and superoxide dismutase. To our knowledge, the study is first among its kind that validates strong positive correlation of viral load with IL-4, IL-6, GR in HBV and IL-6, IL-10, GR in HCV infections. Although, multi-centric studies including large cohorts are required for translating our findings to clinical practice, however, role of these biomarkers with potential diagnostic or prognostic significance might be helpful in clinical assessment of high-risk individuals, thereby, designing interventional strategies, towards development of personalized medicare. The results of our study also offer valuable insights of immune signaling mediators engaged in development of hepatocellular carcinoma.     

Beyond Epistemological Deficits: Dynamic explanations of engineering students’ difficulties with mathematical sense-making

Researchers have argued against deficit-based explanations of students’ difficulties with mathematical sense-making, pointing instead to factors such as epistemology. Students’ beliefs about knowledge and learning can hinder the activation and integration of productive knowledge they have. Such explanations, however, risk falling into a ‘deficit trap’—substituting a concepts/skills deficit with an epistemological one. Our interview-based case study of a freshman engineering major, ‘Jim,’ explains his difficulty solving a physics problem (on hydrostatic pressure) in terms of his epistemology, but avoids a deficit trap by modeling the dynamics of his epistemological stabilities and shifts in terms of fine-grained cognitive elements that include the seeds of epistemological expertise. Specifically, during a problem-solving episode in the interview, Jim reaches and sticks with an incorrect answer that violates common sense. We show that Jim has all the mathematical skills and physics knowledge he would need to resolve the contradiction. We argue that his difficulty doing so stems in part from his epistemological views that (i) physics equations are much more trustworthy than everyday reasoning, and (ii) physics equations do not express meaning that tractably connects to common sense. For these reasons, he does not view reconciling between common sense and formalism as either necessary or plausible to accomplish. But Jim’s in-the-moment shift to a more sophisticated epistemological stance highlights the seeds of epistemological expertise that were present all along: he does see common sense as connected to formalism (though not always tractably so), and in some circumstances, this connection is both salient and valued.
