The routinization of innovation research : A constructively critical review of the state-of-the-science

Abstract: Summary In this review we argue that facilitators of innovation at the individual, group, and organizational levels have been reliably identified, and that validated process models of innovation have been developed. However, a content analysis of selected research published between 1997 and 2002 suggests a routinization of innovation research, with a heavy focus on replication–extension, cross-sectional designs, and a single level of analysis. We discuss five innovative pathways for future work: Study innovation as an independent variable, across cultures, within a multi-level framework, and use meta-analysis and triangulation. To illustrate we propose a ‘distress-related innovation’ model of the relations between negatively connotated variables and innovation at the individual, group, and organizational levels of analysis. Copyright # 2004 John Wiley & Sons, Ltd. Imaginative writers, the reader will have noticed, dropped out of this [Soviet] history when it moved from the 1920’s into the period of Stalinism. Of course industrious typewriters continued to manufacture novels, plays and poems, but they no longer revealed authors in search of the authentic self and true community, as the works of Olesha and Babel had, not to speak of the pre-revolutionary masters. From 1930 to 1953 Stalin’s engineers of human souls typed out their works to formula. Their product has its fascinations, like mass-market fiction and popular drama in the West, but hardly for understanding the psychologies of high culture. They help one understand mass psychology in its relation with the authorities.

Development and validation of a game addiction scale for adolescents

Abstract: The aim of this study was to develop and validate a scale to measure computer and videogame addiction. Inspired by earlier theories and research on game addiction, we created 21 items to measure seven underlying criteria (i.e., salience, tolerance, mood modification, relapse, withdrawal, conflict, and problems). The dimensional structure of the scale was investigated in two independent samples of adolescent gamers (N = 352 and N = 369). In both samples, a second-order factor model described our data best. The 21-item scale, as well as a shortened 7-item version, showed high reliabilities. Furthermore, both versions showed good concurrent validity across samples, as indicated by the consistent correlations with usage, loneliness, life satisfaction, social competence, and aggression.

Foci and correlates of organizational identification

Abstract: Adopting the social identity perspective on organizational identification proposed by Ashforth and Mael (1989), the present study tested two hypotheses concerning the importance of work-group identification (WID) relative to organizational identification (OID). WID was predicted to be stronger than OID as well as more predictive of organizational attitudes and behaviour. Data about employees’ WID, OID, job satisfaction, turnover intentions, job involvement, and job motivation from two samples (N = 76 and N = 163) supported these predictions. We conclude that our understanding of organizational attitudes and behaviour has much to gain by an open eye for the multiple foci of identification that are associated with organizational membership, and that managerial practice may benefit from an increased focus on the work group.

The paradox of intragroup conflict: A meta-analysis.

Abstract: Since the meta-analysis by De Dreu and Weingart (2003b) on the effects of intragroup conflict on group outcomes, more than 80 new empirical studies of conflict have been conducted, often investigating more complex, moderated relationships between conflict and group outcomes, as well as new types of intragroup conflict, such as process conflict. To explore the trends in this new body of literature, we conducted a meta-analysis of 116 empirical studies of intragroup conflict (n = 8,880 groups) and its relationship with group outcomes. To address the heterogeneity across the studies included in the meta-analysis, we also investigated a number of moderating variables. Stable negative relationships were found between relationship and process conflict and group outcomes. In contrast to the results of De Dreu and Weingart, we did not find a strong and negative association between task conflict and group performance. Analyses of main effects as well as moderator analyses revealed a more complex picture. Task conflict and group performance were more positively related among studies where the association between task and relationship conflict was relatively weak, in studies conducted among top management teams rather than non-top management teams, and in studies where performance was measured in terms of financial performance or decision quality rather than overall performance.
