无独立请求权的第三人法律地位之我见

由于我国民诉法关于无独立请求权的第三人制度的规定过于简略 ,以致在理论和实务中对无独立请求权的第三人诉讼地位的认识分歧较大 ,这不仅影响了法律实施的统一 ,更损害了案外人的合法权益。应正确认识无独立请求权的第三人的诉讼地位 ,对其参加诉讼的程序加以理顺。     

客户价值模型及对企业价值影响的研究

本文在对现有客户价值组成估算方法及企业股东价值(Shareholder Value,SHV)理念的局限性进行评价和分析的基础上,提出了计算客户整个生命周期价值(Lifetime Value,LTV)的客户价值(Customer Value,CV)模型;并简要分析了客户价值对提升企业价值的促进作用。通过运用CV模型计算出更准确的FCFF,本文亦提出了新的SHV计算模型。文章最后对模型的数据获得途径进行了简要介绍。     

隐喻应用意识与词汇记忆技巧——关于英语词汇学习方法的创新研究

隐喻是一种复杂的认知现象,同时也是一种非常特殊的语言现象。隐喻意识的提升对帮助学生加强词汇记忆有着重要作用。教学实验表明:很多比喻性用语往往可以追溯到一个共同的喻题或源域,用喻题或源域来对词汇进行归类有助于记忆生疏的比喻性用语。因此,有必要多组织一些旨在提高语言学习者隐喻意识的课堂活动,将隐喻意识变成词汇习得的一个新的渠道。

The empirical analysis of the -bilateral optimized combinatorial auction model

This study proposes a new and highly efficient dynamic combinatorial auction mechanism—the N-bilateral optimized combinatorial auction (N-BOCA). N-BOCA is a flexible iterative combinatorial auction model that offers more optimized trading for multiple suppliers and purchasers in the supply chain than one-sided combinatorial auction. We design the N-BOCA model from the perspectives of market architecture, trading rules, and decision strategy for winner determination, the decision strategy for winner determination needs flexible optimization modeling capability. Thus rule-based reasoning was applied for reflecting the flexible decision strategies. We also show the viability of N-BOCA through Paired Samples T-test experimentation. It shows that N-BOCA yields higher purchase efficiency and effectiveness than the one-auctioneer to multi-bidders (1-to-N) combinatorial auction mechanism.     

The Black male teacher: a 10-year content analysis of empirical research

ABSTRACT

The purpose of this study was to characterize the last decade of Black male teacher empirical research. The present study aimed to elucidate the most salient themes, commonalities, and departures in the literature on Black male educators. A quantitative content analysis was performed to systematically characterize the research trends present in this line of inquiry. The data were collected using an inductively generated coding scheme. A sample of n = 31 studies were identified and examined from articles published between 2006 and 2016. Then frequency data were computed to characterize the data under investigation. The study results indicate that Black male teacher research is nuanced and burgeoning, despite several lapses in article production. The results of this study contribute to the literature on Black male teacher recruitment, retention, and experiences by providing a survey of current research trends that suggest areas of strength, as well as challenges warranting further consideration.     

从赵均刻本编目体例探窥《玉台新咏》古本之遗

本文对《玉台新咏》赵均刻本的编目实况进行细致考察,发现其卷首目录的编辑体例包括[作者名＋诗题或诗类名＋总篇数]和[作者名＋总篇数]两种格式,前者属于中古时期习用的体例,具有相当明显的时代性;其正文编目体例包括“题附辞后”和“题置辞前”两种格式,其中“题附辞后”的编目格式以及双重编目格式并存一书的现象至唐以后已属罕见。较之五云溪馆本和冯班抄本,赵均刻本更多的保留了徐陵旧本原始痕迹,当为目前最可靠的覆宋本。     

使用种次号加辅助区分号对“同类书”的集中方法

由于在文献分类编目工作中会遇到各种内容相同,而在装帧形式、版本形式等方面不同的“同类书”,而将这些“同类书”在目录组织进而在分类排架中组织在一起十分困难,为了方便读者对比和选择使用,阐述了采用种次号加辅助区分号将这些“同类书”集中的具体方法,结果表明,此种方法不仅目录组织清晰,还有助于读者对图书的检索和利用。     

人力资本与教授收入

自从建国以来 ,教授收入一直是下降的。改革后 ,教授收入总体上低于其人力资本价值的状况仍未得到扭转。造成这种状况的原因是多方面的 ,但根本原因在于传统的高等教育体制不合理与无效率 ;在于高教领域里缺少激励—约束机制 ;冗员过多 ,而在分配上又向非教学人员倾斜 ;在于高校间缺少竞争与淘汰机制 ,使教育家兼企业家型的校长无法形成 ,也无人对教授的人力资本进行负责的评价。现行职称评定体系存在着严重的弊端 ,导致教授“市场”出现“柠檬市场”。在短期内因退出障碍虽不会出现“劣币逐良币” ,但在长期内 ,教授学术水平下降则是必然的。
