入选百种杰出学术期刊的特征分析与持续影响力对策 总被引：1，自引：1，他引：0
【目的】对2012-2014年高校主办科技期刊入选"百种中国杰出学术期刊" 的典型特征进行研究。【方法】 分析入选期刊重要文献指标的变化。【结果】 指出在所属学科中期刊综合评价总分领先和影响因子、学科影响指标、他引率等文献计量指标居前是科技期刊入选百种杰出学术期刊的关键,用影响因子当量值可预测今后入选的期刊。结合《中国矿业大学学报》蝉联百种杰出学术期刊的工作实践,提出编辑在初审来稿创新时应注重的3个层次和关注的3个方面因素。【结论】 把握期刊组稿优先方向,注重在稿源、评审质量、编辑水平和传播速度4个方面提高期刊的竞争力,有助于期刊今后入选百种杰出学术期刊。 相似文献

从1992年3月至2003年2月,全国已有775所高校先后合并组建为314所新的高校(其中普通高校289所,成人高校25所)。有149所新组建的高校启用了新的校名,其中137所新高校的命名采用了“升格”的语用形式,即提升名称的意义等级或扩充名称的意义含量。升格校名占新用校名总数的91.1%。到2003年12月为止,我国大陆1553所高校的校名形成了以下各有命名原型的范畴化类型:(一)“地名 性质类名”型。以这样的方式命名的高校有258所。此类校名采用学科名“零形式”,对其学科、专业没有明确的界说,联想义丰富,有综合性大学的示意,且颇有气势,语符简洁,传播的… 相似文献

Knowledge of the natural and the social are irreducibly different yet have much in common. The differences lie at the levels of complexity they engage, modes of explanation they adopt, investigation aims they allow and whether they assert a ‘double hermeneutic’ effect to the behaviour of the studied objects. Knowledge are in common in that they are all construed out of available resources, justified based on the consequences of acting upon them, settled until better alternatives emerge, and serving as walking sticks for beating unknown paths in human life. Because of this, there can be no hierarchy of knowledge or unity of methodology, and dialogical encounters guided by situational ethics, not professional deafness driven by ontological/instrumental fallacies, are a viable strategy for morally and practically wise actions, including knowledge management projects. 相似文献

A macroscopic frost heave model with more clear parameters was established. Based on a porosity rate frost heave model and segregation potential theory, a porosity rate function was deduced and introduced into the stress-strain relationship. Numerical simulation was conducted and verified by frost heave tests. Results show that the porosity rate within the frozen fringe is proportional to the square of temperature gradient and current porosity, and is also proportional to the exponential function of applied pressure. The relative errors between the calculated and measured results of frost depth and frost heave are within 3% and 15% respectively, demonstrating that the temperature gradient, applied pressure and current porosity are the main influencing factors, while temperature is just the constraint of frozen fringe. The improved model have meaningful and accessible parameters, which can be used in engineering with good accuracy. 相似文献

Nonaka's recent incorporation of Giddens into the knowledge movement is superficial and problematic. The incorporation accepts uncritically Giddens's controversial conceptions of structure and agency, avoids his concerns of power and domination, exaggerates his elaboration on contradictions, and shares with him the search for an omelette-like theoretical totalising. Using Giddens as an illustrative vehicle, this paper analyses the pattern of Nonaka’s recent borrowing of others’ work and the consequent tensions built up in his simplistic model of the knowledge creating company. 相似文献
