Validating the Willingness to Self-Censor Scale: Individual Differences in the Effect of the Climate of Opinion on Opinion Expression

Hayes, Glynn, and Shanahan (2005) defined self-censorship asthe withholding of one’s opinion around an audience perceivedto disagree with that opinion. They argued that people differin their willingness to self-censor and introduced an 8-itemself-report instrument, the Willingness to Self-Censor scale,to measure this individual difference. The results of an experimentalstudy presented here provide further evidence of the constructvalidity of the scale. Each participant in the study was presentedwith a hypothetical scenario that contained information suggestinga group of people the participant was conversing with abouta controversial topic held opinions that were either uniformlysimilar to or different from the participant’s own opinion.Four weeks prior, each participant had responded to the Willingnessto Self-Censor scale and a measure of dispositional shyness.As expected, the manipulation of the climate of opinion affectedwillingness to express an opinion to the group, but more soamong those who scored relatively high on the Willingness toSelf-Censor scale. These results support the notion that somepeople rely on information about the climate of opinion moreso than do others when they decide whether or not to voice theiropinion publicly, and they suggest that the Willingness to Self-Censorscale measures this individual difference.     

知识服务转型中的版权制度调适

以"知识付费"为代表的新兴知识服务是基于网络时空而产生的全新知识生产和分享空间,围绕知识作品使用的各种权利义务关系也都随之颠覆与重构,引发了知识服务在"思想/表达""成本/效率""围墙/自由"方面的版权矛盾与冲突.出版业等数字内容产业在知识服务转型的过程中,应当从建立和完善侵权监察制度、版权许可方式、版权合作机制和版权经营理念等方面做好相应的版权制度调适.     

基于信息融合的档案知识服务研究

基于信息融合的档案知识服务,是借助信息融合的理念和技术,对档案信息资源、用户需求信息等进行综合处理与协同利用,推动档案信息资源在数据层面的关联和知识层面的重构,实现面向用户需求的档案知识发现和知识服务的过程.论文构建了由一个目标、两种资源、三个模块、四个环节构成的基于信息融合的档案知识服务框架,并从多源信息获取、信息综合处理、信息融合和档案知识服务方面,探讨了基于信息融合的档案知识服务实现流程.     

Lighting the Shroud of Turin for Exhibition in 2015

ABSTRACT

Lighting a cultural heritage artifact requires balancing visual perception with preventive conservation, by providing the best lighting (in terms of spectral distribution and quantity) to enable the viewer to appreciate details and color, while limiting photo-induced degradation. The paper outlines the methodology applied by a multi-disciplinary team while lighting the Shroud of Turin at its last public exhibition in 2015. The methodology considered the special requirements of the Shroud, including exposure to ultraviolet light, while providing appropriate display conditions that would meet audience expectations. The desired appearance (readability of the body image and color) was defined with the help of Shroud researchers and confirmed by subjective tests, while appropriate light levels for preservation were set in agreement with standard requirements and using knowledge of the degradation of linen in visible and UV light. The installation provided a controlled environment and a managed visitor route to the Shroud, assuring excellent perception of both details and color, with the lowest illuminance level about 15?lx.

Reasons for Student Engagement in Extra-Class Communication

This study extends instructional communication research on extra-class communication (ECC) by presenting an integrative analysis comparing the explanatory utility of student- and instructor-oriented reasons for student engagement in frequent ECC. Results from 495 college students suggested that student-oriented reasons, specifically the relational and functional student motives, were the only significant, positive predictors of students’ perceptions of frequent ECC engagement. Other student motives (excuse making, participation, sycophancy) and perceptions of instructor approachability did not significantly predict perceived frequency of ECC engagement.     

19世纪美国主日学校图书馆研究

美国主日学校图书馆是十九世纪基督教传教活动的一种辅助设施,以向儿童进行宗教和伦理教化为主要目的。作为公共图书馆兴起以前重要的图书馆形态,其定位、功能与作用值得系统深入的研究。主日学校图书馆的创设始于19世纪初期,1850年左右成为美国提供宗教文献和儿童读物的主要渠道,其广泛建立和发展一直持续到1880年,之后日渐式微。主日学校图书馆藏书重点由宗教文献向通俗童书过渡;分类编目处于草创阶段,较为粗略;读者服务规章严格,以闭架借阅为主;率先向儿童免费开放,是儿童图书馆事业的基石;培养儿童阅读习惯,促进了美国基础教育的发展;突破阶级、种族和性别壁垒,促进了公共图书馆民主、平等与包容等服务理念的形成;遍布美国各地,奠定了农村图书馆事业发展的基础。表1。参考文献38。

Retrieving and classifying instances of source code plagiarism

Automatic detection of source code plagiarism is an important research field for both the commercial software industry and within the research community. Existing methods of plagiarism detection primarily involve exhaustive pairwise document comparison, which does not scale well for large software collections. To achieve scalability, we approach the problem from an information retrieval (IR) perspective. We retrieve a ranked list of candidate documents in response to a pseudo-query representation constructed from each source code document in the collection. The challenge in source code document retrieval is that the standard bag-of-words (BoW) representation model for such documents is likely to result in many false positives being retrieved, because of the use of identical programming language specific constructs and keywords. To address this problem, we make use of an abstract syntax tree (AST) representation of the source code documents. While the IR approach is efficient, it is essentially unsupervised in nature. To further improve its effectiveness, we apply a supervised classifier (pre-trained with features extracted from sample plagiarized source code pairs) on the top ranked retrieved documents. We report experiments on the SOCO-2014 dataset comprising 12K Java source files with almost 1M lines of code. Our experiments confirm that the AST based approach produces significantly better retrieval effectiveness than a standard BoW representation, i.e., the AST based approach is able to identify a higher number of plagiarized source code documents at top ranks in response to a query source code document. The supervised classifier, trained on features extracted from sample plagiarized source code pairs, is shown to effectively filter and thus further improve the ranked list of retrieved candidate plagiarized documents.
