“Text mining” covers a range of techniques that allow software to extract information from text documents. It is not a new technology, but it has recently received spotlight attention due to the emergence of Big Data. The applications of text mining are very diverse and span multiple disciplines, ranging from biomedicine to legal, business intelligence and security. From a legal perspective, text mining touches upon several areas of law, including contract law, copyright law and database law. This contribution discusses the legal issues encountered during the assembly of texts into so-called “corpora”, as well as the use of such corpora. 相似文献

In the fall of 2014, the Government of Canada formally split the role of the Chief Public Health Officer (CPHO) into two positions: the CPHO and the President of the Public Health Agency of Canada. Despite concerns raised by the public health community, these changes are consistent with the CPHO's authority. However, the nature of responsible government means that the CPHO cannot simultaneously serve as an independent advocate for policies and programs that might prevent disease and as a senior advisor to the government of the day. 相似文献

This article reports the results of a study that replicates and extends the impression-driven model of candidate evaluation reported in Lodge, McGraw, and Stroh (1989). This model holds that evaluations are formed and updated on-line as information is encountered, and that as a result, citizens need not rely on specific information available from memory to form their candidate evaluations. In the present work we explore whether the order in which information is encountered, as well as whether information that is personally important, influences the weight accorded to evidence in on-line processing. In addition, differences in information-processing strategies due to political sophistication are examined. The results indicate that important information receives more weight than unimportant information. In addition, the evidence suggests that political sophisticates are more efficient on-line processors than are less sophisticated individuals. The implications of these results for models of candidate evaluation are discussed. 相似文献

There is increasing evidence that issues influence voter preferences during the nomination campaign (Bartels, 1985; Bartels, 1988); however, only Bartels (1988) and Conover and Feldman (1986, 1989) have examined how partisans forge perceptions of candidates' positions on issues prior to the general election campaign. The goal of this paper, then, is to examine how individuals develop perceptions of candidates' issue positions during the crucial months leading to the nominating conventions. Relying on theories developed in social-psychology, I tested five competing hypotheses known to influence individuals' perceptions of candidates' issue positions. An examination of the findings revealed that there is strong support for one of the hypotheses and modest support for three additional hypotheses. In summary, it appears that voters are quite ingenious in forming impressions of where candidates stand on the issues. They rely on stored information about politics, they actually adjust candidates' true positions to relieve cognitive inconsistencies, they evoke their own issue positions to assume candidates they like agree with them and candidates they dislike disagree with them, and finally they evoke their own issue positions to assume candidates agree with them even when they hold no sentiment toward the candidate. 相似文献

The role of governmental risk aversion in the decision to privatize the production of goods and services has not been examined closely. Using a model of a risk-averse, single-service Niskanen bureaucrat, we determine the conditions under which a bureaucrat will prefer to privatize rather than produce in-house. If the private-sector firm is risk neutral, the result will be a fixed-fee contract with complete insurance. If the private-sector firm is risk averse, the result will be a cost-plus contract with the degree of cost sharing determined by the bureaucrat's share of total risk aversion. In both cases, the bureaucrat's sponsor may affect the likelihood of privatization by manipulating the rewards and penalties imposed on the bureaucrat. 相似文献

The community power debate concluded with each side believing they had won. Political theorists have generalized power, making empirical investigation very difficult; urban scholars have turned their attention to more manageable empirical problems. Rational choice advances the debate, exposing the errors of all sides and facilitating a new approach which transcends structural versus individualist methods. By separating various aspects of power in urban contexts, complementary techniques such as network analysis in a bargaining framework, semi-structured interviewing and the use of text databases permits a comprehensive investigation of agenda-setting and the mobilization of bias. The paper demonstrates the utility of this approach by comparing it to 'regime theory', the latest paradigm of urban research. 相似文献

How do natural disasters affect electoral participation? The existing social science literature offers contradictory predictions. A considerable body of research in sociology and psychology suggests that traumatic events can inspire pro-social behaviour, which might increase turnout. Yet, political science has long held that even minor changes to participation costs of low benefit activities can lead to considerable drops in civic engagement. Consequently, natural disasters should reduce electoral participation. We show how these distinct views can be jointly analysed within the Riker–Ordeshook model of voting. This paper then reports results on the impact of the 2002 and 2013 floods in Germany on turnout in federal and state elections in Saxony and Bavaria, conducted few weeks after the floods. Analysing community level turnout data, and drawing on a difference-in-differences framework, we find that flood exposure has a consistent negative effect on turnout. This indicates that the increase in the costs of voting outweighed any increase in political engagement in our case and stands in contrast to findings from developing contexts, where flood management was convincingly linked to electoral participation. 相似文献
