利用GoWeb、PubMed及ISIS系统评价医学期刊对研究热点的把握度

以哮喘机制研究为例,使用GoWeb生物医学专业搜索引擎搜索学科领域研究热点,以PubMed文献检索服务系统来源的国外权威期刊和ISIS系统检索获得的国家自然科学基金项目为评价标准,比较国内权威医学期刊对学科领域研究热点及其发展趋势的把握度.结果发现,免疫学、气道重塑、表观遗传学为哮喘机制研究3大热点,三者发文量或项目数占比之和由高到低排列分别为《中华医学杂志》(96.0％)、国家自然科学基金项目(89.5％)、国外权威期刊(87.0％)、《中华结核与呼吸杂志》(75.7％).与国外权威期刊及国家自然科学基金项目相比较,国内权威期刊中免疫学机制比例较高,而气道重建比例较低,表观遗传学研究见于国外权威期刊、国家自然科学基金项目及《中华医学杂志》中,发文量或项目数占比基本相当;在国内期刊中,《中华医学杂志》对哮喘机制研究热点的把握度较好.基于GoWeb对科技期刊研究领域进行对比分析有利于医学期刊及其编辑把握有关领域的研究热点及其发展趋势,组织发表紧跟国际研究热点的高水平的医学科研论文.

天津市微小企业主的知识素质开发

微小企业主在管理活动中的职能具有极大的综合性,其必须具备一定的基础文化知识,还要懂得生产操作,善于设计和开发,而且要具备多方面的管理能力。对天津市微小企业主知识素质现状的调查表明,企业主的基础文化程度普遍偏低,管理知识匮乏,大部人没有参加过相关培训。鉴于此,建议:引导企业主树立正确的自我定位,激发其企业家精神;引导企业主形成注重自身知识素质的意识;积极组织开展对微小企业主的教育与培训。     

Molecularly imprinted polymers as the extracted sorbents of clenbuterol ahead of liquid chromatographic determination

A pre-treatment methodology for clenbuterol hydrochloride (CLEN) isolation and enrichment in a complex matrix environment was developed through exploiting molecularly imprinted polymers (MIPs). CLEN-imprinted polymers were synthesized by the combined use of ally-β-cyclodextrin (ally-β-CD) and methacrylic acid (MAA), allyl-β-CD and acrylonitrile (AN), and allyl-β-CD and methyl methacrylate (MMA) as the binary functional monomers. MAA-linked allyl-β-CD MIPs (M-MAA) were characterized by Fourier transform-infrared (FT-IR) spectroscopy and a scanning electron microscope (SEM). Based upon the results, M-MAA polymers generally proved to be an excellent selective extraction compared to its references: AN-linked allyl-β-CD MIPs (M-AN) and MMA-linked allyl-β-CD MIPs (M-MMA). M-MAA polymers were eventually chosen to run through a molecularly imprinted solid-phase extraction (MISPE) micro-column to enrich CLEN residues spiked in pig livers. A high recovery was achieved, ranging from 91.03% to 96.76% with relative standard deviation (RSD) ≤4.45%.

The Development of the Olympic Narrative in Chinese Elite Sport Discourse from Its First Successful Olympic Bid to the Post-Beijing Games Era

Abstract

As a phenomenon exogenous to China, the Olympics have been proactively interpreted in the local context since China’s entry (and subsequent re-entry in 1984) into the Olympic movement. With China’s increasing involvement in promoting three bids to host the Olympic Games, two of which were successful, respectively, in 2001 and 2015, the nature of the discourse of key stakeholders in relation to Chinese elite sport has both reflected and reshaped the meaning of the Games to Chinese elite sport. This paper examines the discursive construction process of the Olympics in the Chinese elite sport system by key stakeholders through analyzing statements of political figures on sport and Olympic phenomena, Chinese elite sport policy documents, and the commentaries of leading Chinese sport academics. The analysis of discourse highlights two main features in the construction of the Games in official accounts during the period under investigation. The development of these two themes reflects the nature of the Chinese Olympic discourse, manifests the political power over the interpretation of the Olympics in Chinese context, and continues to characterize the on-going major themes in Chinese elite sport policy.

承租人的优先购买权若干问题初探

承租人的优先购买权问题是优先权制度中的一个方面，优先权作为民事立法所确立的制度由来已久，近年来随着市场经济的进一步发展，特别是我国住房制度的改革、货币化分房的进一步推进，房产交易市场异常活跃，房屋租赁合同和房屋买卖合同应用日渐广泛。其中就承租人的优先购买权行使问题出现了大量的纠纷。在司法实践中，关于承租人的优先购买权问题的规定相对偏少，而且过于原则。本文拟就承租人的优先购买权的概念、特征及其法律依据、行使条件和立法完善作一些初步探索，以期对审判实践有所裨益。
