Identifying different registers of digital literacy in virtual learning environments

In this paper social semiotics, and systemic functional linguistics in particular, are used in order to identify registers of digital literacy in the use of virtual learning environments. The framework of social semiotics provides means to systemize and discuss digital literacy as a linguistic and semiotic issue. The following research question was investigated in the paper: What different registers of digital literacy could be identified when students and teachers communicate and interact in a VLE?The research question was answered by, initially, an application of social semiotics to virtual learning environments, and its relation to the knowledge domains of everyday, specialized and reflexive digital literacy. This application was then further developed, using an analysis of a course specific use of a virtual learning environment in a case study. The study identified discrepancies between the digital literacies of teachers, designers and students. These discrepancies mean that a shared semiotic register was sometimes difficult to maintain. The conclusion is that the designers and teachers as co-designers of virtual learning environments need a better understanding of everyday digital literacy in order to design more sufficient learning environments. The paper shows that digital literacy must be considered as a situated practice, and that it concerns functional and communicative competencies rather than acquiring a set of technical skills.     

Sexual Socialization Messages in Television Programming Produced for Adolescents

This study examined sexual content in American prime-time programs popular among the tween (9–14 years of age) audience on broadcast networks and programs aired on the most popular adolescent TV networks—an understudied area of media research. Consistent with past research, the majority of broadcast shows contained sexual talk and behaviors, as did adolescent shows. No significant difference was observed between the two types of shows regarding the frequency with which sexual behaviors were presented in a given hour of TV programming. The amount of scene focus paid to sexual themes varied, but studio audiences were almost always heard positively reinforcing these messages. The findings are discussed with respect to social cognitive and cultivation theories.     

A comparison between the workplace cultures of Saudi Arabia's private and public education institutes

In Saudi Arabia, it is generally perceived that private special education institutes (SEIs) provide a higher quality education than their public counterparts. Parents tend to trust and invest in private rather than public institutes. This is principally attributed to the greater financial capacity of private special institutes, which ensures services can be provided more effectively. Investigating this perspective, this study seeks to bridge the gap often observed and commented upon between public and private SEIs, and to reflect critically on how the needs of all students with intellectual disabilities can be met within the public system. A comparative case study of two SEIs in Saudi Arabia for students with intellectual disabilities, one public and one private, was designed. Semi-structured interviews were conducted with parents, teachers and principals. A key finding of this study is that there is a major difference in the workplace cultures of public and private institutes. This results in several observable factors that were found to contribute to the quality of provision for learners.

The role of inter-organizational relationships in the development of patents: A knowledge-based approach

This paper examines the role of various inter-organizational relationships in patent development, and how these relationships contribute to patent competitiveness. It takes the perspective of individual inventors and describes how they utilize external knowledge in the development of patents. Based on a case study of a European telecom operator, we found interaction with R&D consortia, suppliers and customers to support inventors in the development of new ideas for patents and in solving related problems. In terms of patent competitiveness, buyer-seller relationships were more valuable for an operator than R&D consortia relationships, as they reduced the market and technology uncertainty related to the patent.     

Harsh Parenting and Child Externalizing Behavior: Skin Conductance Level Reactivity as a Moderator

Skin conductance level reactivity (SCLR) was examined as a moderator of the association between harsh parenting and child externalizing behavior. Participants were 251 boys and girls (8–9 years). Mothers and fathers provided reports of harsh parenting and their children's externalizing behavior; children also provided reports of harsh parenting. SCLR was assessed in response to a socioemotional stress task and a problem-solving challenge task. Regression analyses revealed that the association between harsh parenting and externalizing behavior was stronger among children with lower SCLR, as compared to children with higher SCLR. SCLR may be a more robust moderator among boys compared to girls. Results are discussed with regard to theories on antisocial behavior and multiple-domain models of child development.     

Exposure to Interparental Conflict and Children''s Adjustment and Physical Health: The Moderating Role of Vagal Tone

Physiological regulation, as indexed by baseline vagal tone and delta vagal tone (the change in vagal tone during an attention-demanding or challenging task), was examined as a moderator in the relations between exposure to verbal and physical parental marital conflict and children's adjustment and physical health. Higher vagal tone was posited to serve a protective function (i.e., buffer) for children exposed to higher levels of marital conflict. Seventy-five 8- to 12-year-olds and their mothers completed measures of parental conflict, and children's adjustment and physical health. Children's vagal tone was assessed during baseline conditions and during exposure to an audiotaped interadult argument. Results indicate that higher vagal tone buffered children against increased externalizing, internalizing, and health problems related to exposure to more frequent marital conflict, especially verbal conflict. Further, higher levels of delta vagal tone protected boys against externalizing problems associated with verbal conflict, and health problems associated with physical conflict.
