When the Romance is Over: Follower Perspectives of Aversive Leadership
While leadership is indisputably one of the most pervasive topics in our society, the vast majority of existing research has focused on leadership as a positive force. Taking a follower- centric approach to the study of leadership, we integrate research on the Romance of Leadership and the dark side of leadership by examining followersâ perceptions of aversive leadership in the context of public high schools. Although Meindl, Ehrlich, and Dukerich (1985) demonstrated that the Romance of Leadership also includes the overattribution of negative outcomes to leaders, subsequent research has failed to explore the implications of this potentially darker side of romanticizing leaders. Specifically, we examine perceptions of principalsâ aversive leadership and traditional affective, behavioral, and performance outcomes of followers in a sample of 342 dyads. Followers assessed their principalsâ leadership behaviors and self-rated their levels of job satisfaction, self-efficacy, and resistance, while principals assessed their followersâ citizenship behaviors, complaining behaviors, and job performance. Results show that perceptions of aversive leadership are positively related to follower resistance and negatively related to followersâ job satisfaction. In addition, a usefulness analysis revealed that follower-rated variables were significantly related to perceptions of aversive leadership above and beyond leader-rated variables, suggesting that the relationship between negative outcomes and aversive leadership may be more constructed than real. In sum, the tendency to romanticize leadership may also lead to a proclivity to readily misattribute or overattribute blame to leadership as a convenient scapegoat for negative outcomes.
Alors que le leadership est incontestablement lâun des thĂšmes les plus envahissants de notre sociĂ©tĂ©, la grande majoritĂ© des recherches existantes a portĂ© sur le leadership en tant que force positive. En adoptant une approche centrĂ©e sur le suiveur dans lâĂ©tude du leadership, nous examinant la perception quâont les collaborateurs du leadership insupportable dans le contexte des lycĂ©es publics. Quoique Meindl, Ehrlich, et Dukerich (1985) aient montrĂ© que la Romance du Leadership inclut aussi la surattribution de rĂ©sultats nĂ©gatifs aux leaders, les recherches ultĂ©rieures ont mĂ©connu les implications de cet aspect potentiellement plus sombre des leaders idylliques. Nous analysons en particulier sur un Ă©chantillon de 342 dyades la perception du leadership rĂ©pulsif du proviseur et les rĂ©sultats habituels des collaborateurs en rapport avec lâaffectivitĂ©, le comportement et les performances. Les collaborateurs ont notĂ© les comportements de leadership de leur proviseur et auto-Ă©valuĂ© leur niveau de satisfaction au travail, dâefficience et de rĂ©sistance, alors que les proviseurs apprĂ©ciaient les conduites de citoyennetĂ© et de revendication, ainsi que la performance professionnelle. Les rĂ©sultats montrent que la perception du leadership rĂ©pulsif est Positivement reliĂ©e Ă la rĂ©sistance du suiveur et nĂ©gativement Ă sa satisfaction professionnelle. En outre, une analyse des plus fructueuses a rĂ©vĂ©lĂ© que les variables Ă©valuĂ©es par les collaborateurs Ă©taient significativement en relation avec la perception du leadership rĂ©pulsif, bien plus quâavec les variables Ă©valuĂ©es par les leaders, ce qui indique que la relation entre les rĂ©sultats mĂ©diocres et le leadership nĂ©gatif serait plus construite que rĂ©elle. Au total, le penchant Ă lâidĂ©alisation du leadership peut aussi bien conduire Ă une propension Ă trop facilement condamner Ă tort et Ă travers le leadership quâĂ la dĂ©signation dâun bouc Ă©missaire tout trouvĂ© pour expliquer de mauvais rĂ©sultats

CD5 mRNA expression and auto-antibody production in early human B cells immortalized by EBV
A number of studies have suggested that lymphocytes producing polyreactive antibodies belong to the CD5+ B-cell subset. In this study we have examined CD5 at the cell surface and mRNA levels in EBV-driven cord blood and fetal liver clones previously characterized in terms of their antibody specificities. We show that EBV-immortalized cells can express surface CD5, and that some of the clones not expressing surface CD5 express it at the mRNA level. The complete absence of CD5 mRNA in some polyreactive clones is consistent with the proposition that the production of auto-antibodies and multispecific antibodies is not restricted to the CD5+ B-cell subset
