ABSTRACTMoral Foundations Theory (MFT) and the Model of Intuitive Morality and Exemplars (MIME) contend that moral judgments are built on a universal set of basic moral intuitions. A large body of research has supported many of MFT’s and the MIME’s central hypotheses. Yet, an important prerequisite of this research—the ability to extract latent moral content represented in media stimuli with a reliable procedure—has not been systematically studied. In this article, we subject different extraction procedures to rigorous tests, underscore challenges by identifying a range of reliabilities, develop new reliability test and coding procedures employing computational methods, and provide solutions that maximize the reliability and validity of moral intuition extraction. In six content analytical studies, including a large crowd-based study, we demonstrate that: (1) traditional content analytical approaches lead to rather low reliabilities; (2) variation in coding reliabilities can be predicted by both text features and characteristics of the human coders; and (3) reliability is largely unaffected by the detail of coder training. We show that a coding task with simplified training and a coding technique that treats moral foundations as fast, spontaneous intuitions leads to acceptable inter-rater agreement, and potentially to more valid moral intuition extractions. While this study was motivated by issues related to MFT and MIME research, the methods and findings in this study have implications for extracting latent content from text narratives that go beyond moral information. Accordingly, we provide a tool for researchers interested in applying this new approach in their own work. 相似文献

ABSTRACTThis article examines the role of web archives as a critical source of data for conducting computational communication research. Web archives are large-scale databases containing comprehensive records of websites showing how those websites have evolved over time. Recent communication scholarship using web archives is reviewed, demonstrating the breadth of research conducted in this space. Subsequently, a methodological framework is proposed for using web archives in computational communication research. As a source of data, web archives present a number of methodological challenges, particularly with regards to the accuracy and completeness of web archives. These problems are addressed in order to better inform future work in this area. The closing sections outline a forward-looking trajectory for computational communication research using web archives. 相似文献

Various studies report that cultural journalism increasingly focuses on service and entertainment instead of serious arts coverage. The press prioritizes popular culture over traditional high arts to a growing extent. However, this shift in journalistic attention does not necessarily signify a straightforward decline in aesthetic standards, as popular cultural forms like film have developed along the lines of high art principles in the past decades. This article charts trends in American, Dutch, French, and German film journalism between 1955 and 2005. It demonstrates that coverage is typified by a serious aesthetic approach from the 1970s onwards. The principles of art are seen to steer journalists’ attention to an important degree: the review remains the predominant journalistic genre, and newspapers devote more attention to films by prestigious directors than strictly commercial moviemakers. As such, film’s prominence in the press does not seem to indicate a decline in serious cultural journalism but rather a revaluation of a popular cultural form. 相似文献

The medical ultrasonic phased array technology was modified for the non-destructive testing of marble sculptures and the feasibility of the approach was evaluated. For this purpose, 1?MHz, 64-channel phased array electronic and phased array transducers were developed. The specifications of the electronics and the transducers are presented and discussed. Ultrasound images of inner structures of a marble sculpture are presented. The problem of the acoustic matching layers for different states of deterioration is discussed and the developments in view of a suitable matching layer solution are presented. This matching layer is combined with a new coupling technique that protects the marble surface. The results of experiments on ultrasound phantoms and on a marble sculpture are presented. 相似文献
