论褚伯秀《南华真经义海纂微》注庄“视脚”

褚伯秀的《南华真经义海纂微》纂集了从西晋的郭象至南宋的林希逸等十三家注,是现存最早的《庄子》集注作品。该书纂集众注,断以己意;兼顾音训,注重义理;擘肌分理,唯务折衷,在庄学研究史上意义重大。褚伯秀身为道教中人,却以独特之“视脚”涵摄了儒释道诸多视角,努力克服以偏概全、挂一漏万的弊端,他的这种通化的根性值得我们重视。     

Educational Assortative Mating and Income Dynamics in Couples: A Longitudinal Dyadic Perspective

The question of how educational assortative mating may transform couples' lives and within‐family gender inequality has gained increasing attention. Using 25 waves (1979–2012) of data from the National Longitudinal Survey of Youth 1979 and longitudinal multilevel dyad models, this study investigated how educational assortative mating shapes income dynamics in couples during the marital life course. Couples were grouped into three categories—educational hypergamy (wives less educated than their husbands), homogamy, and hypogamy (wives more educated than their husbands). Results show that change in husbands' income with marital duration is similar across couples, whereas change in wives' income varies by educational assortative mating, with wives in educational hypogamy exhibiting more positive change in income during the marital life course. The finding that husbands' long‐term economic advancement is less affected than that of wives by educational assortative mating underscores the gender‐asymmetric nature of spousal influence in heterosexual marriages.     

Bounds on the domination number of a digraph

A vertex subset S of a digraph D is called a dominating set of D if every vertex not in S is adjacent from at least one vertex in S. The domination number of D, denoted by \(\gamma (D)\), is the minimum cardinality of a dominating set of D. The Slater number \(s\ell (D)\) is the smallest integer t such that t added to the sum of the first t terms of the non-increasing out-degree sequence of D is at least as large as the order of D. For any digraph D of order n with maximum out-degree \(\Delta ^+\), it is known that \(\gamma (D)\ge \lceil n/(\Delta ^++1)\rceil \). We show that \(\gamma (D)\ge s\ell (D)\ge \lceil n/(\Delta ^++1)\rceil \) and the difference between \(s\ell (D)\) and \(\lceil n/(\Delta ^++1)\rceil \) can be arbitrarily large. In particular, for an oriented tree T of order n with \(n_0\) vertices of out-degree 0, we show that \((n-n_0+1)/2\le s\ell (T)\le \gamma (T)\le 2s\ell (T)-1\) and moreover, each value between the lower bound \(s\ell (T)\) and the upper bound \(2s\ell (T)-1\) is attainable by \(\gamma (T)\) for some oriented trees. Further, we characterize the oriented trees T for which \(s\ell (T)=(n-n_0+1)/2\) hold and show that the difference between \(s\ell (T)\) and \((n-n_0+1)/2\) can be arbitrarily large. Some other elementary properties involving the Slater number are also presented.     

创新网络嵌入与高技术企业研发人员创新绩效关系研究

 创新驱动的实质是人才驱动,企业技术管理的重要核心之一是人员管理。研发人员是高技术企业的核心人力资本和主导资源,具有典型的稀缺性、创造性、主导性、体验性以及高信息需求等异质性特征,能否采取切实有效措施满足研发人员的异质性需求,激活其创新潜力和活力,是提升高技术企业创新绩效和管理技术人员的关键。        聚焦于高技术企业研发人员的异质性需求特征,运用创新网络嵌入理论,提出创新网络嵌入、创新效能感与创新绩效的关系假设模型;借鉴成熟量表,设计相关测量变量的调查问卷;利用Spss 19.0和Amos 21.0软件,对北京、上海、武汉、广州等地高技术企业研发人员的269个调查数据进行分析,考察创新网络嵌入对研发人员创新绩效的影响和作用机理,并验证创新效能感的中介作用。        研究结果表明,高技术企业研发人员的创新网络结构嵌入对创新过程和创新结果均具有显著正向影响,而关系嵌入仅对创新过程具有正向影响;创新网络结构嵌入和关系嵌入对创新效能感均具有显著正向影响,创新效能感对创新过程和创新结果具有显著正向影响;创新效能感在研发人员结构嵌入和关系嵌入对创新过程的影响中起完全中介作用,在结构嵌入对创新结果的影响中起部分中介作用。        从技术人员创新绩效管理的微观视角入手,探究高技术企业研发人员创新绩效的内涵、实质和影响因素,对高技术企业研发人员的创新网络嵌入与创新绩效的关系、创新效能感的中介作用以及创新网络嵌入与创新绩效的关系研究中关系嵌入悖论进行实证检验和解读,提出提升高技术企业研发人员创新绩效的创新网络嵌入式开发策略,包括聚焦产学研战略协同和集群创新、强化关系网络建设和位置管理、营造宽松氛围以提升创新效能感等。     

汉代文人五言诗的交际意图探究

汉代文人五言诗有着作者丰富的交际意图,这些交际意图是通过诗歌中的前景化设置和话语暗含表达出来的。"游子"形象的前景化设置表达了汉代文人对仕途的追求;"思妇"形象的前景化设置表达了汉代文人对爱情的渴盼。从话语暗含的角度来看,汉代文人五言诗中的思妇诗在一定程度上也是作者追求仕途的寄托之作。

白寿彝先生的民俗学实践与理论

白寿彝的民俗学研究表现在两个方面,一是收集整理地方文化中的民俗资料,二是进行相关的民俗现象研究。前者主要体现在对《开封歌谣集》的收集整理上,作为民国时期民俗学研究领军人物顾颉刚先生的学生,白寿彝通过编辑这部歌谣集,来反映诸多社会问题,表达对下层民众的关注,追求唤起民智的目标。后者先后体现在若干单篇论文中,其新中国成立以前论文主要是对封建迷信的歌谣观的梳理,特点是多取材于正史;其新中国成立以后论文主旨在于辨析民俗学中的传说思想,特点是取材于当代人的研究成果和充分利用传世文献,同时批评相关无学理意义的论断。这两方面的民俗学研究体现出白寿彝在民俗学理论方面的深厚修养,以及民俗学与历史学密切结合、关注下层民众、适应时代发展需要的高度自觉,至今具有一定的示范和借鉴价值。
