The role of patenting activity for scientific research: A study of academic inventors from China's nanotechnology

Scientists from universities are becoming more proactive in their efforts to commercialize research results. Patenting, as an important channel of university knowledge transfer, has initiated a controversy on potential effects for the future of scientific research. This paper contributes to the growing study on the relationship between patenting and publishing among faculty members with China's evidence in the field of nanotechnology. Data from top 32 most prolific universities in patenting are used to examine the relationship, consisting of 6321 confirmed academic inventors who both publish and patent over the time period 1991–2008. By controlling for heterogeneity of patenting activities, patenting experience, institutional affiliation and collaboration with foreign researchers, the findings in China's nanotechnology generally support earlier investigations concluding that patenting activity does not adversely affect research output. Patenting, however, has negative impacts on both quantity and quality of university researchers’ publication output, when the assignee lists include corporations or scientists themselves.

Necessary and sufficient criteria for asynchronous stabilization of Markovian jump systems

This paper is concerned with asynchronous stabilization for a class of discrete-time Markovian jump systems. The mode of designed controller is considered to be not perfectly synchronous with the activated mode of the Markovian jump system. In order to achieve the asymptotic stability with asynchronous controller, a conditional probability is introduced to describe the asynchronism of system and controller modes, which is dependent on the active system mode. Besides, due to the difficulty in acquiring all the mode transition probabilities in practice, the transition probabilities of the Markovian jump system and the controllers are supposed to be partially unknown. A necessary and sufficient condition is developed to guarantee the stochastic stability of the resultant closed-loop system and further extended to asynchronous stabilization with partially known transition probabilities. Finally, the effectiveness and advantages of the proposed methods are demonstrated by two illustrative examples.     

Stability and bifurcation of delay-coupled genetic regulatory networks with hub structure

In this paper, we study the local stability and bifurcation of a delay-coupled genetic regulatory networks consisting of two modes with the hub structure. By analyzing the equilibrium equation, the number of the positive equilibria is discussed in both the cases that there are inhibition coupling and activation coupling in the networks. It is revealed that multiple equilibria could exist in the developed genetic networks and the number of the equilibria could be distinct under the two cases of delayed-coupling. For the equilibrium, the conditions of the coupling-delay-independent stability and the saddle-node bifurcation are derived with respect to the biochemical parameters. The coupling-delay-dependent stability and the Hopf bifurcation criteria on the biological parameters and the coupling delay are also given. Moreover, the complexity of the algorithm used in this paper is analyzed. The numerical simulations are made to certify the obtained results. The multistability of the developed genetic regulatory networks is displayed. The different effects of the coupling delay on the stability of the genetic networks under different biochemical parameters are shown.     

Applying user analytics to uses and effects of social media in China

ABSTRACT

We introduce what user analytics can do in the first half of the paper and then illustrate how to do user analytics in the second half. In the current context, user analytics refers to a set of diverse communication research methods on uses and effects of social media. User analytics has evolved from TV ratings research to online user research. The history illustrates what data sources, measures, and analyses can be used for what types of research questions under user analytics. We discuss the similarities of and differences between user analytics and other methods of computational communication research (e.g. content mining and online experiments), and compare the strengths and weaknesses of user analytics with traditional quantitative methods (e.g. survey). Finally, we present an application study of Chinese bloggers to demonstrate how to employ user analytics methods to study the production, consumption, and effects of user-generated content.     

《九云记》作者国籍问题新考

《九云记》是据朝鲜小说《九云梦》增演而成的汉文白话小说,又曾吸纳数十部中国小说的内容,在东亚古小说史上具有特殊地位。其作者的国籍问题曾引发激烈讨论,为"1998年文坛十大论争"之一,然囿于材料,迄无定论。利用新见《九云楼》抄本可重作探讨,首先回应中国小说论者的三大力证:《碧芦集》等文献记载歧见迭出,难成定论;小说的中国色彩因袭自中国小说并衍生出种种漏隙;不同来源文本白话语言优劣悬殊,作者并不娴于白话。其次从有关中国地理描述的反常讹误与朝鲜视角,词汇语法使用的非中文母语痕迹与朝鲜指向等认定:《九云记》作者是朝鲜人。
