根据《韦伯新学院词典》的注释,"令人可信的(to be credible)"被定义为:能够提供一些合乎逻辑的,使人信服的理由。然而,一些报社的编辑表达了另外的思考。他们认为,"公信力"这个概念应该增加一个额外的维度,即报纸在社区中保持和谐和领导地位。  相似文献

Can constrained relevance feedback and display strategies help users retrieve items on mobile devices?     

Vishwa Vinay  Ingemar J. Cox  Natasa Milic-Frayling  Ken Wood 《Information Retrieval》2006,9(4):435-453

Searching online information resources using mobile devices is affected by small screens which can display only a fraction of ranked search results. In this paper we investigate whether the search effort can be reduced by means of a simple user feedback: for a screenful of search results the user is encouraged to indicate a single most relevant document. In our approach we exploit the fact that, for small display sizes and limited user actions, we can construct a user decision tree representing all possible outcomes of the user interaction with the system. Examining the trees we can compute an upper limit on relevance feedback performance. In this study we consider three standard feedback algorithms: Rocchio, Robertson/Sparck-Jones (RSJ) and a Bayesian algorithm. We evaluate them in conjunction with two strategies for presenting search results: a document ranking that attempts to maximize information gain from the user’s choices and the top-D ranked documents. Experimental results indicate that for RSJ feedback which involves an explicit feature selection policy, the greedy top-D display is more appropriate. For the other two algorithms, the exploratory display that maximizes information gain produces better results. We conducted a user study to compare the performance of the relevance feedback methods with real users and compare the results with the findings from the tree analysis. This comparison between the simulations and real user behaviour indicates that the Bayesian algorithm, coupled with the sampled display, is the most effective.

The Dynamics of Opinion Formation in Local Popular Referendums: Why the Dutch Always Say No   总被引：1，自引：0，他引：1  

Neijens  Peter; van Praag  Philip 《Int. Journal of Public Opinion Research》2006,18(4):445-462

There is growing research on voting behavior in referendums.However, the dynamics of opinion formation in popular referendums,referendums initiated by the electorate to approve or rejectdecisions made by representative bodies, has not yet been studied.This is especially unfortunate as voting decisions in popularreferendums differ from those in other referendums in interestingways. Opinion formation can be a very dynamic process in popularreferendums, making the referendum campaign crucial. This paperstudies the dynamics of opinion formation in popular referendumsand relates them to particular characteristics of the campaignsand the issues at hand. Based on the literature, we consideredthe effects of the intensity of the yes and no campaigns, familiaritywith the issue, and partisan cues. Our study uses content analysisdata and data from public opinion surveys dealing with variouspopular referendums held in the Netherlands. The study revealedseveral factors that contributed to the volatility of opinionsin the referendum campaigns: the issue (new and did not fittraditional political schemes), lack of support from societaland community organizations for the position of the local authorities,and low profile campaigns on the part of local authorities.While some of these factors are general and may play a rolein referendums everywhere, some can be considered ‘typicallyDutch’, related to the characteristics of popular referendumsin the Netherlands and the country’s political system.  相似文献   

Evaluation of Internet Information Sources by High School Students in Ghana     

Philip Kwaku Kankam 《International Information and Library Review》2018,50(2):88-93

The Internet clearly presents the opportunity for students to expand their knowledge at a fast pace, since they are able to access enormous amount of information. However, accessing the Internet also has its downside since not all information is of good quality. The study explored how 12th grade students at a high school in Ghana evaluated online information sources. These students and the head of the Information Communication Technology department respond to self-administered questionnaires and a semi-structured interview, respectively. The study found that most of the high school students did some kind of an evaluation of online information sources, however, they were not applying the right criteria. The study further revealed that students were not introduced to evaluation criteria at school and this had contributed to the gap in their evaluation competencies.  相似文献   

Along the Write Lines: a case study exploring activities to enable creative writing in a secondary English classroom.     

Audrey B. Wood 《English in Education》2016,50(2):130-147

This article arises from a four week study of a class of 14‐15 year old students. The study explored students’ perception of themselves as writers and the effects of a variety of teaching and learning strategies on their creative writing responses. The aim of the project was to enhance the students’ creative writing, whilst ascertaining whether there were particular activities or types of writing that would lead to students perceiving more satisfactory outcomes in their writing. It answers the research question: What do I observe, and what do my students say, about the experience of different classroom based creative writing tasks?  相似文献
