Exploring the impact of perceived LMX variability within work teams

According to Leader-Member Exchange (LMX) theory, leaders develop different quaUt}' reladonships with the employees they supervise. To date, Utde research has invesdgated the impact of such differendadon by the leader on workplace outcomes. The current research proposes a novel way to capture the extent of LMX variabiUt}' within a single work team, and subsequently investigates the impact of perceived LMX variability on workplace outcomes. Across multiple employed samples, participants reported poorer team relations (as indicated by low team cohesion and high conflict) when they perceived LMX variability to be high. Perceptions of poor team relations further impacted negatively upon individual affect variables. The findings suggest that leaders may need to exercise caution when developing different quality relationships amongst individuals within the same work team.

The influence of communication sources on perceived risk about purchasing online

In this paper we report on a qualitative study into the influence of personal and non-personal communication sources in creating, sustaining and/or mediating people's perceptions of risk about purchasing online. In terms of non-personal communication sources, our findings suggest that the popular media significantly influence both purchasers and nonpurchasers’ perceptions of risk about using the Web for purchasing. Despite these negative perceptions, those who have purchased online appear to pay little attention to change agent communications on websites, such as logos, icons and statements about secure payment systems, which are designed to alleviate these concerns. In terms of inter-personal communication sources, our findings suggest that while there is evidence that to some degree, friends or peers influenced the interviewees about purchasing online, the purchasers in our study indicated that they would not influence others to do the same. We conclude our paper with suggestions for future interpretive research into the influence of communication sources on acceptance of the Web for purchasing.

Influencing the perceived emotions of music with intent

Music is an immensely powerful affective medium that pervades our everyday life. With ever advancing technology, the reproduction and application of music for emotive and information transfer purposes has never been more prevalent. In this paper we introduce a rule-based engine for influencing the perceived emotions of music. Based on empirical music psychology, we attempt to formalise the relationship between musical elements and their perceived emotion. We examine the modification to structural aspects of music to allow for a graduated transition between perceived emotive states. This engine is intended to provide music reproduction systems with a finer grained control over this affective medium; where perceived musical emotion can be influenced with intent. This intent comes from both an external application and the audience. Using a series of affective computing technologies, an audience’s response metrics and attitudes can be incorporated to model this intent. A generative feedback loop is set up between the external application, the influencing process and the audience’s response to this, which together shape the modification of musical structure. The effectiveness of our rule system for influencing perceived musical emotion was examined in earlier work, with a small test study providing generally encouraging results.
