Increasing Staff and Student Capacity to Use the Communication Facility in Queen's Online in Order to Support Learning and Teaching on a BSW Programme

In this article the authors explore and evaluate developments in the use of information and communications technologies (ICT) within social work education at Queen's University Belfast since the inception of the new degree in social work. They look at the staff development strategy utilised to increase teacher confidence and competence in use of the Queen's Online virtual learning environment tools as well as the student experience of participation in modules involving online discussions. The authors conclude that the project provided further opportunity to reflect on how ICT can be used as a platform to support a whole course in a systematic and coordinated way and to ensure all staff remained abreast of ongoing developments in the use of ICT to support learning which is a normative expectation of students entering universities. A very satisfying outcome for the leaders is our observation of the emergence of other 'experts' in different aspects of use of ICT amongst the staff team. This project also shows that taking a team as opposed to an individual approach can be particularly beneficial

Are Shy Adults Really Bolder Online? It Depends on the Context

We examined whether individual differences in shyness and context influenced the amount of computer-mediated self-disclosure and use of affective language during an unfamiliar dyadic social interaction. Unfamiliar young adults were selected for high and low self-reported shyness and paired in mixed dyads (one shy and one nonshy). Each dyad was randomly assigned to either a live webcam or no webcam condition. Participants then engaged in a 20-minute online free chat over the Internet in the laboratory. Free chat conversations were archived, and the transcripts were objectively coded for traditional communication variables, conversational style, and the use of affective language. As predicted, shy adults engaged in significantly fewer spontaneous self-disclosures than did their nonshy counterparts only in the webcam condition. Shy versus nonshy adults did not differ on spontaneous self-disclosures in the no webcam condition. However, context did not influence the use of computer-mediated affective language. Although shy adults used significantly less active and pleasant words than their nonshy counterparts, these differences were not related to webcam condition. The present findings replicate and extend earlier work on shyness, context, and computer-mediated communication to a selected sample of shy adults. Findings suggest that context may influence some, but not all, aspects of social communication in shy adults.

Is shyness context specific? Relation between shyness and online self-disclosure with and without a live webcam in young adults

The Internet provides a new tool to investigate old questions in experimental social psychology regarding Person x Context interaction. We examined the interaction of self-reported shyness and context on computer-mediated communication measures. Sixty female undergraduates unfamiliar were paired in dyads and engaged in a 10 min free chat conversation on the Internet with and without a live webcam. Free chat conversations were archived, transcripts were objectively coded for communication variables, and a linear mixed model used for data analysis of dyadic interaction was performed on each communication measure. As predicted, increases in self-reported shyness were significantly related to decreases in the number of prompted self-disclosures (after controlling for the number of opportunities to self-disclose) only in the webcam condition. Self-reported shyness was not related to the number of prompted self-disclosures in the no webcam condition, suggesting that shyness was context dependent. The present study appears to be the first to objectively code measures of Internet behaviour in relation to the study of personality in general and shyness in particular. Theoretical and clinical implications for understanding the contextual nature of shyness are discussed. (C) 2006 Elsevier Inc. All rights reserved.

Online CORDIC algorithm and VLSI architecture for implementing QR-array processors

A novel most significant digit first CORDIC architecture is presented that is suitable for the VLSI design of systolic array processor cells for performing QR decomposition. This is based on an on-line CORDIC algorithm with a constant scale factor and a latency independent of the wordlength. This has been derived through the extension of previously published CORDIC algorithms. It is shown that simplifying the calculation of convergence bounds also greatly simplifies the derivation of suitable VLSI architectures. Design studies, based on a 0.35-µ CMOS standard cell process, indicate that 20 such QR processor cells operating at rates suitable for radar beamfoming can be readily accommodated on a single chip.

Trust considerations on attitudes towards online purchasing: The moderating effect of privacy and security concerns

The research examines the relationships between three common trust considerations (vendor, Internet and third parties) and attitudes towards online purchasing. The study incorporates privacy and security concerns as a moderating variable and finds that these relationships vary depending on the level of concerns a consumer has when purchasing online. The study suggests that "fears" surrounding the Internet as a place to do business still hinder the use of it for e-commerce purposes, but that the presence of a reputable agent might in some manner mitigate this risk. In the context of business to consumer relationships trust in the vendor is important for the consumer to accept any risk associated with a transaction. Theoretical implications for online customer behavior theory are also discussed. © 2009 Elsevier Inc.

Understanding online customer repurchasing intention and the mediating role of trust - an empirical investigation in two developed countries

Although e-commerce adoption and customers initial purchasing behavior have been well studied in the literature, repeat purchase intention and its antecedents remain understudied. This study proposes a model to understand the extent to which trust mediates the effects of vendor-specific factors on customers intention to repurchase from an online vendor. The model was tested and validated in two different country settings. We found that trust fully mediates the relationships between perceived reputation, perceived capability of order fulfillment, and repurchasing intention, and partially mediates the relationship between perceived website quality and repurchasing intention in both countries. Moreover, multi-group analysis reveals no significant between-country differences of the model with regards to the antecedents and outcomes of trust, except the effect of reputation on trust. Academic and practical implications and future research are discussed. © 2009 Operational Research Society Ltd.
