Rare Metals, EarlyView.ABSTRACT Internal oxidation has been identified as an effective method for enhancing the strength of AgMg alloys. However, the concurrent occurrence of embrittlement remains inadequately understood, thus limiting their broader application. This study investigates the oxidation behavior of AgMg alloys with Mg concentrations ranging from 1 at% to 7 at ...

A Study of Fund Manager’s Ability about Open Mutual Fund Performance [PDF]
, 2013 中国开放式基金市场经理能力如何呢？目前，国内学界对于此并没有统一的结论。本文选取了2004年至2011年9月30日中国开放式基金数据，剔除了基金经理更换因素的影响，按照同一基金经理管理分期的原则对中国开放式基金经理能力进行了全面的分析。这个角度在目前国内关于开放式基金经理能力研究中尚属空白。在中国基金经理更换现象频繁，同时由于基金经理是基金的管理者，不同基金经理能力必然不同，只有剔除了基金经理更换因素才能深层次全面的分析基金经理能力。本文主要解决四个问题：采用TM以及HM模型对基金经理能力进行归因分析 ...

Theoretical and Empirical Research on Performance Evaluation of Listed Open-end Fund (LOF) in China [PDF]
, 2014 目前，中国基金市场发展越来越迅速，尤其是开放式基金，已经成为了投资者最重要的投资工具之一，因此越来越多的学者开始对中国开放式基金的绩效进行分析研究。作为创新型的开放式基金，上市型开放式基金（LOF）结合了封闭式基金和开放式基金的优势，因此LOF的绩效研究就显得更有实践价值。本文选取LOF作为研究对象，对其总体绩效，择券能力、择时能力以及绩效的归因进行了比较全面系统的分析。 本文选取了2005年到2013年间39支LOF进行研究，通过使用多因素模型和单因素模型进行对比分析 ...

How much biotic nativeness matters across human demographic groups
Conservation Biology, EarlyView.Abstract Many central concepts of conservation biology—such as nativeness—are structured by ecological and social factors. However, the social consequences of using these concepts to make conservation decisions remain inadequately understood. Some researchers argue that nativeness, rather than acting as an objective proxy for important ecological ...

, 2019 独立学院的教师职业倦怠并不仅仅是个体心理层面的问题,而是具有规模效应的社会学问题。从表面上看,职业倦怠是由独立学院教师的薪酬待遇低、职称评比难、身份地位不高等外在因素造成的;但从社会学角度进行分析,独立学院教师的职业倦怠其实是时间结构与空间结构双重夹击下形成的社会问题。这一问题的解决不可能依赖于个别化的心理干预,而是呼吁社会的整体性改变。福建省中青年教师教育科研项目“社会结构视域下独立学院学生评教失效原因探究”(JAS180930 ...
