Computational text analysis has become an exciting research field with many applications in communication research. It can be a difficult method to apply, however, because it requires knowledge of various techniques, and the software required to perform most of these techniques is not readily available in common statistical software packages. In this teacher’s corner, we address these barriers by providing an overview of general steps and operations in a computational text analysis project, and demonstrate how each step can be performed using the R statistical software. As a popular open-source platform, R has an extensive user community that develops and maintains a wide range of text analysis packages. We show that these packages make it easy to perform advanced text analytics. 相似文献

The findings of an investigation assessing the differential effects of psycholinguistic training programs are reported. Methodologically, meta‐analysis, the analysis of analyses, was used to determine whether psycholinguistic training programs differentially affect the abilities measured by the Illinois Test of Psycholinguistic Abilities (ITPA). When findings were integrated by ITPA subtests, ITPA constructs, and salient study features, the training programs were found to differ with respect to improving psycholinguistic abilities. Overall results, however, indicated that the Peabody Language Development Kits (PDLK) were more consistently advantageous than either ITPA related programs or other types of training activities (e.g. structured teaching and perceptual‐motor approaches). These findings were validated in a multiple regression analysis comparing the three intervention methods. It was suggested that the structured and sequential nature of the PDLK was the major factor contributing to its greater effectiveness. 相似文献

Luciano Floridi argues that every existing entity is deserving of at least minimal moral respect in virtue of having intrinsic value qua information object. In this essay, I attempt a comprehensive assessment of this important view as well as the arguments Floridi offers in support of it. I conclude both that the arguments are insufficient and that the thesis itself is substantively implausible from the standpoint of ordinary intuitions. 相似文献

This article develops and tests a model examining the relationship between firm globalization, scope of e-commerce use, and firm performance, using data from a large-scale cross-country survey of firms from three industries. We find that globalization leads to both greater scope of e-commerce use and improved performance, measured as efficiency, coordination, and market impacts. Scope of e-commerce use also leads to greater firm performance of all three types. Globalization has differential effects on B2B and B2C e-commerce, however, such that highly global firms are more likely to do B2B but less likely to do B2C. Our findings provide support for Porter's (1986) thesis that upstream business activities (namely, B2B) are more global while downstream business activities (B2C) are more local or multidomestic. 相似文献
