Reasoning with Intensional Negative Adjectivals: Semantics, Pragmatics, and Context

Intensional negative adjectives alleged , artificial , fake , false , former , and toy are unusual adjectives that depending on context may or may not be restricting functions. A formal theory of their semantics, pragmatics, and context that uniformly accounts for their complex mathematical and computational characteristics and captures some peculiarities of individual adjectives is presented.
Such adjectives are formalized as new concept builders, negation‐like functions that operate on the values of intensional properties of the concepts denoted by their arguments and yield new concepts whose intensional properties have values consistent with the negation of the old values. Understanding these new concepts involves semantics, pragmatics and context‐dependency of natural language. It is argued that intensional negative adjectives can be viewed as a special‐purpose, weaker, conntext‐dependent negationin natural language. The theory explains and predicts many inferences licensed by expressions involving such adjectives. Implementation of sample examples demonstrates its computational feasibility. Computation of context‐dependent interpretation is discussed.
The theory allows one to enhance a knowledge representation system with similar concept building, negation‐like, context‐dependent functions, the availability of which appears to be a distinct characteristic of natural languages.

论高校校报在和谐校园文化建设中作用——以近五年《吉林化工学院报》为例

高校校报作为高校党委和行政的机关报,高等院校重要的新闻舆论工具,以其党委喉舌的权威性,新闻报道的真实性,新闻传播的广泛性等特点决定了它在和谐校园文化建设中担任重要角色。本文以近五年《吉林化工学院报》在校园文化建设中所作的实践探索为案例,采用演绎与实证结合的研究方法,论述了校报有效利用新闻评论、深度报道和文艺副刊的形式在和谐校园文化建设中发挥引导、启迪和熏陶作用时的具体做法。     

Internet dependency and psychosocial maturity among college students

One salient impact of information technology on students' lives is the ever-increasing use of the Internet. Although there exist many reports in the media regarding the unhealthy Internet use among students, research is still limited and has mainly relied upon on-line self-selected reports on Internet dependency or “Internet addiction”. This paper attempts to look into the alleged Internet dependency within the Eriksonian psychosocial development framework. The results of a survey of the Internet use among 217 students in an Australian regional university are reported. The measures of patterns of the Internet use were correlated with that of psychosocial maturity and self-efficacy. The results showed that the Internet dependency seemed to be independent of the psychosocial maturity and the general perceived self-efficacy. A factor analysis extracted six factors from a set of 28 Internet experience-related questions and indicated that the Internet dependency could be of a multifaceted nature. The findings and their implications were discussed and a contextual perspective was proposed.     

面向对象的基于角色访问控制模型的探讨

提出一种应用于分布式系统的面向对象的基于角色访问控制(ORBAC)模型。基于角色访问控制,将权限与角色相关联,用户分配得多个角色从而获得与其关联的权限。引用对象的概念,通过策略控制器集中控制分散管理,为分布式系统提供高效的访问控制机制。模型考虑了静态和动态角色分配,并分析了面向对象访问控制模型的一些动态特性。     

基于自相似业务的网络TCP拥塞控制算法

本文通过对自相似网络模型的分析,采用TCP协议可以直接观测的回环时间（Bound Trip Time)来进行拥塞程度预测,提出一种改进的TCP拥塞控制算法。仿真证明,改进算法在一定程度上提高了网络的整体性能,在自相似程度较高时尤为明显。     

Informed public against false rumor in the social media era: Focusing on social media dependency

This study explores how the public’s belief in false rumors about Middle East Respiratory Syndrome that spread across South Korea related to their accuracy-oriented information seeking as well as the moderating effects of people’s reasons for using social networking services (SNS). The survey results show that perceived credibility of false rumors did not affect accuracy-oriented information seeking. However, a significant result was shown in the moderating effect, such that SNS informational dependency interacted with false rumor credibility on accuracy-oriented information seeking. Overall, this study specifically identifies and discusses differences in SNS dependency and accuracy-oriented information seeking in the context of rumor communication to examine the construction of an informed public. Theoretical contributions of this study are discussed.     

对协作系统自适应角色选择策略的思考

在传统协作系统基础上提出了一种新颖的自适应协作方式——机会角色选择协作.为进一步说明该策略,构建了一种最基本的两用户机会协作框架,其中两个用户相互竞争将各自信息发送给同一目的端.根据瞬时信道条件,两用户均可以机会地充当信息源角色,而另一用户将作为放大转发中继来为信源服务.同时,在此基础上提出并简要描述了一种最优的中心化角色选择策略(C-ROSE).该策略能够最大化目的端接收信噪比(SNR),进而提高系统传输性能.研究表明,通过这种动态、灵活、高效的节点角色分配方式,协作系统的传输可靠性可得到进一步增强,从而为构建稳固、高效、互惠的协作传输体系开辟了新道路.
