As Hong Kong prepares for a political transition in 1997, neither the existing colonial British government nor the impending People's Republic of China (PRC) has established a strong historical foundation for political trust within the territory. In this study, we examine the level of distrust towards the existing and future political regimes, as well as attitudes towards Hong Kong's future. Based on a representative telephone survey of Hong Kong residents (N = 512), we find a high degree of political distrust among respondents, particularly towards the PRC administration. Although initial bivariate analyses establish some association between distrust and media exposure, channel preference, and demographic variables, further multivariate analyses suggest that many of these factors are highly interrelated. One central finding is that among men and those with middle to high socio‐economic status, television news exposure is associated with trust in the PRC. Conversely, women and younger people tend to distrust the PRC, regardless of their news exposure. 相似文献

The only long term trend data on trust in the American press comes from the General Social Survey (GSS). The erosion of trust in the press as measured by the GSS indicator is indisputable, but its implications for the functioning of American democracy depend on what, precisely, is being measured. In this study we use an experimental design embedded in a representative national probability sample to shed light on what people are thinking of when they say they trust or distrust the American press. Are they thinking about the sources they themselves use for news? The sources that are most popular with the population at large? An average of all possible media sources? We find that individuals express much greater trust in the press when they are asked to consider specific news sources than when they are asked to evaluate a generic news media. Our results suggest that an accessibility bias combined with the proliferation of news sources in recent years may lead individuals to think of distrusted sources when asked to answer generic media trust questions. We therefore argue that different measurement strategies are needed to successfully address trust in the press in the current news environment. 相似文献

Governments look at explainable artificial intelligence's (XAI) potential to tackle the criticisms of the opaqueness of algorithmic decision-making with AI. Although XAI is appealing as a solution for automated decisions, the wicked nature of the challenges governments face complicates the use of XAI. Wickedness means that the facts that define a problem are ambiguous and that there is no consensus on the normative criteria for solving this problem. In such a situation, the use of algorithms can result in distrust. Whereas there is much research advancing XAI technology, the focus of this paper is on strategies for explainability. Three illustrative cases are used to show that explainable, data-driven decisions are often not perceived as objective by the public. The context might raise strong incentives to contest and distrust the explanation of AI, and as a consequence, fierce resistance from society is encountered. To overcome the inherent problems of XAI, decisions-specific strategies are proposed to lead to societal acceptance of AI-based decisions. We suggest strategies to embrace explainable decisions and processes, co-create decisions with societal actors, move away from an instrumental to an institutional approach, use competing and value-sensitive algorithms, and mobilize the tacit knowledge of professionals 相似文献

This article examines the mediated construction of citizens during an electoral campaign, a political period in which citizens are normatively expected to play a fundamental role. From a social constructionist, discursive approach, this article qualitatively explores the representation of citizens in the press in the coverage of the main Spanish newspapers (El País, El Mundo, and Abc) during the campaign for the Spanish General Election of 2008. It is understood that the media's portrayal of citizens contributes to spreading and legitimising certain discourses about citizens, about citizens' political behaviour, and also about the reasons behind citizens' political attitudes and motivations. On occasions, these discourses are based on pre-electoral polls or previous research, although many rest only on inferences about the public. The newspapers put forward a reductionistic set of ambivalent discourses naturalising uninformed voting and legitimising the vote for major parties, while sympathising, at the same time, with disenchanted voters, justifying citizens' distrust in politicians. 相似文献

图书馆核心能力:信息服务格局变化中的认识冲突与分析 总被引:3,自引:0,他引:3
在网络技术发展和信息服务格局变化的压力下,学术界就图书馆核心能力问题产生了严重分歧:社会制度观强调从知识或信息保障的制度层面,为图书馆找到一种其他机构不可比拟或无法取代的能力;知识服务观主张通过知识应用和知识创新服务,培育图书馆新的业务生长点;基础业务观则在文献集藏与公共服务两个基本领域,致力于为图书馆核心能力辩护。不同观点之间的冲突,不仅造成学术上的困惑,也带来实践中的迷茫。分析各种代表性观点在图书馆核心能力形成基础、价值取向和认定标准上的认识冲突问题,是探索一种具有基本共识的图书馆核心能力理论的一个重要环节。 相似文献

The popular belief that business management concepts can be applied readily to not-for-profit enterprises needs qualification . Not-for-profit enterprises differ widely; each has its own managerial needs, and many have discriminating constraints that sharply modify which concepts will be effective. 相似文献

Investigating task performance of probabilistic topic models: an empirical study of PLSA and LDA 总被引:2,自引:0,他引:2
Probabilistic topic models have recently attracted much attention because of their successful applications in many text mining
tasks such as retrieval, summarization, categorization, and clustering. Although many existing studies have reported promising
performance of these topic models, none of the work has systematically investigated the task performance of topic models;
as a result, some critical questions that may affect the performance of all applications of topic models are mostly unanswered,
particularly how to choose between competing models, how multiple local maxima affect task performance, and how to set parameters
in topic models. In this paper, we address these questions by conducting a systematic investigation of two representative
probabilistic topic models, probabilistic latent semantic analysis (PLSA) and Latent Dirichlet Allocation (LDA), using three
representative text mining tasks, including document clustering, text categorization, and ad-hoc retrieval. The analysis of
our experimental results provides deeper understanding of topic models and many useful insights about how to optimize the
performance of topic models for these typical tasks. The task-based evaluation framework is generalizable to other topic models
in the family of either PLSA or LDA. 相似文献

This article traces the trajectory from distrust to trust in written records as proof of the conveyance of land in England
between the eleventh and seventeenth centuries. During that period of time, such records were transformed from an aide-memoire
of an essentially oral act, to the indisputable proof of the act they recorded and, finally, to the very embodiment of the
act itself. The article focuses specifically on one particular class of conveyance, i.e., transfers of freehold interests
in land held by free tenure, on one particular form of conveyance, i.e., feoffments with livery of seisin, and on one particular
type of record, i.e., the charters that recorded such conveyances. The article concludes that the ascension of written proof
by the end of the 17th century is attributable to a number of factors, among them, the growth of royal jurisdiction over land,
the rise of literacy, the growth of commerce, and an increasing distrust on the part of the judiciary in the capacity of a
lay jury to properly assess written records. 相似文献

Evaluation and assessment of reference services, reference collections, and reference librarians at academic libraries is a concern shared by many. New methods and criteria are debated extensively in library literature. Rarely, however, has any attention been given to the concepts of diversity and multiculturalism when planning strategies for assessing and evaluating staff and collections. Perhaps with the advent of curriculum that supports pluralism and the changing demographics of many communities and campuses, the time has come to examine the commitment reference departments are willing to make to strengthen and diversify their staff and collections. 相似文献
