Andressen, P., Konradt, U., & Neck, C. P. (2012). The relation between self-leadership and transformational leadership: Competing models and the moderating role of virtuality.
Journal of Leadership and Organizational Studies, 19, 66–80. doi:10.1177/1548051811425047
This study tries to integrate self-leadership in a traditional leadership model. Therefore it examines the relationship between self-leadership, transformational leadership, and work motivation (i.e. self-efficacy and instrumentality) relative to job performance and affective commitment. In addition the influence of work environment is of interest for a comprehensive leadership model. Thus, the moderating role of virtuality was examined. Three competing models which are theoretically plausible are compared: Self-leadership acting (1) as a process factor mediating the relation between transformational leadership and employees’ motivation, (2) as an input factor, simultaneously with transformational leadership, and (3) as a process factor mediating the relation between work motivation and job performance/ affective commitment. Results from structural equation modeling indicate that self-leadership is a process factor that mediates the relationship between transformational leadership and employees’ motivation. Results further suggest that self-leadership has a higher influence on motivation in virtual work structures compared to co-located work structures. Limitations, implications for management, and suggestions for future research are discussed.
Christophersen, T., & Konradt, U. (2012). Development and validation of a formative and a reflective measure for the assessment of online store usability.
Behaviour & Information Technology, 31, 839–857. doi:10.1080/0144929x.2010.529165
The aim of this study was to develop and validate a reflective and a formative measure of online store usability. Perceived usability, related constructs (i.e. trust and aesthetics), controls (i.e. user and product characteristics), and consequences (i.e. intention to buy and purchase) were examined within a nomological network. 378 participants completed an experimental study. Each participant visited two out of 35 online stores and rated the usability and intention to buy for both stores. Purchase behavior was determined by combining the participants' reward with the decision to buy. Results from PLS structural equation modeling indicate that the formative usability measure forms a valid set of items for the user-based assessment of online store usability and that both measures are positively related to the intention to buy, suggesting criterion validity. As hypothesized, positive relationships of usability with trust and aesthetics were supported. Furthermore, both measures provided a good prediction of the decision to buy, indicating overall predictive validity. Limitations and implications for usability measures and human-computer interaction research are discussed.
Hauschildt, K., & Konradt, U. (2012). Self-Leadership and team members' work role performance.
Journal of Managerial Psychology, 27, 497–517. doi:10.1108/02683941211235409
Purpose – The purpose of the present study is to extend previous research on self-leadership by investigating the relationship between self-leadership and work role performance of team members including individual task and team member proficiency, adaptivity, and proactivity. Moreover, the moderating role of collectivism is examined.
Design/methodology – Organizational team members' self-ratings of self-leadership and six work role performance dimensions (i.e., individual task and team member proficiency, adaptivity, and proactivity, respectively) were collected in a cross-sectional study and were analyzed using Partial Least Squares modeling.
Findings – Results indicate positive relationships between self-leadership and proficiency, adaptivity and proactivity directed both at the individual task and the team. Results also suggest that collectivism moderated the relation between self-leadership and team member proficiency.
Originality/value – Previous research is extended by providing first evidence of self-leadership’s relationship with a differentiated set of individual task and team member work roles including adaptive and proactive performance aspects.
Practical implications – Managerial implications for personnel selection, leadership, training, and organizational development efforts are provided.
Hauschildt, K., & Konradt, U. (2012). The effect of self-leadership on individual’s job performance in teams.
Leadership, 8, 145–168. doi:10.1177/1742715011429588
This research examined the effect of self-leadership strategies on individuals’ work role performance in teams. Using an experimental policy-capturing design, self-leadership, task interdependence and situational uncertainty were manipulated in two studies. Moreover, the moderating effect of psychological collectivism orientation on the self-leadership performance relation was explored. Results from multilevel analyses revealed that in Study 1, self-leadership had a positive effect on individual task and team member work role performance. Study 2 replicated and extended these results by showing positive effects of self-leadership on individuals’ team member proficiency, adaptivity and proactivity in teams. Furthermore, collectivism orientation moderates the effect of self-leadership on team member proficiency. Implications of the findings are identified, limitations are discussed, and areas for future research are proposed.
Konradt, U., Held, H., Christophersen, T., & Nerdinger, F. W. (2012). The role of usability in e-commerce service.
International Journal of E-Business Research , 8, 56–75. doi:10.4018/jebr.2012100104
We examined the impact of perceived usability of websites of commercial service vendors on consumer’s affective, intentional, and behavioral variables. Reflective and formative usability measures were used within a nomological network of predictors (trust, reputation, and perceived fun), mediators (user satisfaction, and intention to use), decision to choose as the criteria, product involvement as a moderator, and controls. Results from structural equation modeling revealed that usability holds both direct and indirect paths, via trust and perceived fun, to user satisfaction. User satisfaction was positively related to the intention to use and partially mediated the relation between usability and intention to use. Furthermore, product involvement does not moderate the relation between usability and intention to use and the relation between user satisfaction and intention to use. Finally, intention to use provided an excellent prediction of the decision to choose. Limitations and suggestions for future research are discussed.
Konradt, U., Lueckel, L., & Ellwart, T. (2012). The role of usability in business-to-business e-commerce systems: Predictors and its impact on user’s strain and commercial transactions.
Advances in Human-Computer Interaction. Open access article ID 948693. doi:10.1155/2012/948693
This study examines the impact of organizational antecedences (i.e., organizational support, and information policy) and technical antecedences (i.e., subjective server response time, and objective server response time) to perceived usability, perceived strain, and commercial transactions (i.e. purchases) in business-to-business (B2B) e-commerce. Data were gathered from a web-based study with 491 employees using e-procurement bookseller portals. Structural equation modeling results revealed positive relationships of organizational support and information policy, and negative relationships of subjective server response time to usability after controlling for users’ age, gender, and computer experience. Perceived usability held negative relationships to perceived strain and fully mediated the relation between the three significant antecedences and perceived strain while purchases were not predicted. Results are discussed in terms of theoretical implications and consequences for successfully designing and implementing B2B e-commerce information systems.
