Media Violence and Adolescents’ ADHD-Related Behaviors: The Role of Parental Mediation

We examined the role of parental media mediation in the relationship between media violence and adolescents’ ADHD-related behaviors. Survey data from 1,017 adolescents (10–14 years) show that parents can play an important role in this relationship, depending on the media mediation strategies that they use (i.e., restrictive or active mediation) and how they apply these strategies (i.e., in a controlling, inconsistent, or autonomy-supportive way). Our findings support the notion that contextual factors are critical in understanding media effects, and provide directions for how parents can manage their adolescents’ violent media use, and possibly by extension, their ADHD-related behaviors.

Comparison of the predictive validities of two McCarthy short forms

Scores on Kaufman's (1977) McCarthy short form and the McCarthy Screening Test (1978) were obtained for a sample of 53 first graders in their first month of school. Nine months later, the Metropolitan Achievement Test was administered to the sample. The correlation between Kaufman's estimated General Cognitive Index and the Metropolitan Basic Battery raw score was .71. Biserial correlations between “At Risk” and “Not At Risk” classifications of the McCarthy Screening Test and Metropolitan Basic Battery raw scores ranged from .43 to .78. Kaufman's short form scores usually indicated a smaller number of false negatives than did McCarthy Screening Test scores. Implications of these findings for these findings for first-grade screening are discussed.     

A joint learning approach with knowledge injection for zero-shot cross-lingual hate speech detection

Hate speech is an increasingly important societal issue in the era of digital communication. Hateful expressions often make use of figurative language and, although they represent, in some sense, the dark side of language, they are also often prime examples of creative use of language. While hate speech is a global phenomenon, current studies on automatic hate speech detection are typically framed in a monolingual setting. In this work, we explore hate speech detection in low-resource languages by transferring knowledge from a resource-rich language, English, in a zero-shot learning fashion. We experiment with traditional and recent neural architectures, and propose two joint-learning models, using different multilingual language representations to transfer knowledge between pairs of languages. We also evaluate the impact of additional knowledge in our experiment, by incorporating information from a multilingual lexicon of abusive words. The results show that our joint-learning models achieve the best performance on most languages. However, a simple approach that uses machine translation and a pre-trained English language model achieves a robust performance. In contrast, Multilingual BERT fails to obtain a good performance in cross-lingual hate speech detection. We also experimentally found that the external knowledge from a multilingual abusive lexicon is able to improve the models’ performance, specifically in detecting the positive class. The results of our experimental evaluation highlight a number of challenges and issues in this particular task. One of the main challenges is related to the issue of current benchmarks for hate speech detection, in particular how bias related to the topical focus in the datasets influences the classification performance. The insufficient ability of current multilingual language models to transfer knowledge between languages in the specific hate speech detection task also remain an open problem. However, our experimental evaluation and our qualitative analysis show how the explicit integration of linguistic knowledge from a structured abusive language lexicon helps to alleviate this issue.     

Assessing emergent literacy in preschool classrooms

Recent research on the literacy development of children during the preschool years has emphasized the notion of “emergent literacy,” according to authors Kontos (1986) and Teale and Sulzby (1986). According to this view, preschool children learn about reading and writing as they participate in a literate culture. Early social interactions involving print are crucial to children's reading and writing development, according to the Early Childhood and Literacy Development Committee (1986).     

A Case Study of ROI in Organizational Performance of Working at Home

With the growing suburban population, many employees in metro areas are facing long commutes to and from the workplace. According to the 2011 Texas Transportation Institute's Urban Mobility Report, the average commuter experiences 34 hours of delay per year and spends an extra $713 on fuel (see http://tti.tamu.edu/documents/mobility‐report‐2011.pdf ). This not only causes stress for the employee but also has a serious impact on the organization and the environment.
