An increasing number of studies in political communication focus on the “sentiment” or “tone” of news content, political speeches, or advertisements. This growing interest in measuring sentiment coincides with a dramatic increase in the volume of digitized information. Computer automation has a great deal of potential in this new media environment. The objective here is to outline and validate a new automated measurement instrument for sentiment analysis in political texts. Our instrument uses a dictionary-based approach consisting of a simple word count of the frequency of keywords in a text from a predefined dictionary. The design of the freely available Lexicoder Sentiment Dictionary (LSD) is discussed in detail here. The dictionary is tested against a body of human-coded news content, and the resulting codes are also compared to results from nine existing content-analytic dictionaries. Analyses suggest that the LSD produces results that are more systematically related to human coding than are results based on the other available dictionaries. The LSD is thus a useful starting point for a revived discussion about dictionary construction and validation in sentiment analysis for political communication. 相似文献

Product counterfeiting has received increased attention due to its economic and public health impact. Media framing of product counterfeiting shapes how the public and policymakers understand the problem. While there is a large body of literature examining crime and the media generally, empirical studies have yet to focus on the media construction of product counterfeiting. This study presents the results of a content analysis using a random sample of newspaper articles referencing product counterfeiting in the New York Times and the Wall Street Journal from 2000 to 2009. Articles were coded for common patterns in sources of information. While the results indicate the presence of a wide variety of themes, product types, and industries, government and business sources are overrepresented among the sources cited, leading to some level of consistency in the presentation of the impact of and appropriate responses to product counterfeiting. Implications for understanding how the public and policymakers understand product counterfeiting are discussed. 相似文献

This study examines the impact of religious orientation on attitudes toward U.S. Middle Eastern policy among Muslim Lebanese. The data came from a stratified random sample, consisting of 262 Sunni and Shi'i respondents of both genders, conducted in the Greater Beirut area during February and March of 2002. Consistent with the literature about Islamism, the present analysis reveals an empirical distinction between personal and political dimensions of religion in Lebanon. Specifically, support for political Islam is associated with unfavorable attitudes toward U.S. policy in the region, but personal religiosity is unrelated to attitudes toward foreign policy. The study findings contribute in clarifying the debate that has been raging since the September 11 attacks, pitting Islam against the West and associating Islam with political violence. 相似文献

A media storm is a sudden surge in news coverage of an item, producing high attention for a sustained period. Our study represents the first multi-issue, quantitative analysis of storm behavior. We build a theory of the mechanisms that drive media storms and why the “anatomy” of media storms differs from that of non-storm coverage. Specifically, media storm coverage should change less explosively over time, but be more sharply skewed across issues, compared to non-storm coverage. We offer a new method of operationalizing media storms and apply our operationalization to U.S. and Belgian news. Even in these two very different cases, we find a common empirical storm anatomy with properties that differ from those of non-storm coverage in the predicted fashion. We illustrate the effects of media storms on the public through discussion of four key examples, showing that online search behavior responds strongly to media storms. 相似文献

This study examines whether there are differential relationships among trauma exposure, familial risk and protective factors, substance abuse, and posttraumatic stress disorder (PTSD) among incarcerated and non-incarcerated women. A case-control method was used to match 100 incarcerated women with 100 women in the general population. Incarcerated women had a significantly higher risk of trauma exposure as compared with controls, with odds ranging from 1.7 to 3.7. When group was controlled, exposure to sexual or physical trauma significantly increased the odds of PTSD (odds ratio = 5.0; p < .05), as did substance use in response to traumatic distress (odds ratio = 8.9; p < .001). Family-related characteristics did not appear to moderate this relationship. The findings suggest that incarcerated women are at high risk for PTSD given their high rates of trauma exposure and apparent lack of appropriate coping mechanisms; the results support the use of trauma-specific interventions for this population. 相似文献

The final Digital Britain report was published in June as to set out the Government's final proposals and updating an interim version that has been published in January this year. This article builds upon an earlier article in [2009] 25 CLSR 263, which analysed the interim report in depth. The intention is not to repeat that earlier analysis, but rather update it and draw the reader's attention to those key areas of change. 相似文献

论公安执法中的人权保障问题 总被引:1,自引:0,他引:1
公安执法与保障人权是辩证统一的关系,但在当前的公安执法中还存在着许多侵犯人权的问题。在目前的公安执法中,人权保障应主要侧重于对相对人的知情权、陈述申辩权、安全保障权及人格尊严权的保护,实现公安执法中人权保障的途径主要在于树立人权理念、改进公安立法、加大执法监督等方面。 相似文献

针刺麻醉的基础研究虽然主要以现代科学技术为手段,但追溯针刺麻醉的源流与发展、廓清针刺麻醉的临床与研究实践、总结针刺麻醉的理论与技术方法,仍需在足够的古今文献依据基础上完成。古代针刺麻醉文献虽然内容丰富,但整理研究相对薄弱;现代相关文献报道数量较大,但缺乏系统总结。今后针刺麻醉文献研究工作应包括针刺麻醉文献的汇集整理研究、针刺麻醉文献资源数字化规范及标准研究、针刺镇痛与针刺麻醉文献的综合研究、针刺麻醉优势病种的特异性腧穴研究、针刺麻醉的中医理论研究5个方面。 相似文献
