Mutations of the myeloid transcription factor CEBPA are not associated with the blast crisis of chronic myeloid leukaemia

The transcription factor CEBPA is crucial for normal myeloid differentiation. CEBPA gene mutations have been reported in patients with acute myeloid leukaemia. The inevitable evolution of chronic myeloid leukaemia (CML) in chronic phase (CP) to a fatal blast crisis (BC) is assumed to result from the acquisition of additional genetic changes in the leukaemic clone. Gain of CEBPA mutations might represent a key event causing the differentiation block observed in myeloid CML-BC, but not in CML-CP. Here, no CEBPA mutation in 95 CML-BC patients was found, suggesting a limited role, if any, of CEBPA mutations in this disorder.

Gender-fair language in the context of leadership: Preventing the lack of fit for women

Women are still underrepresented in leadership due to a perceived a ‘lack of fit’. Thus, women are hired less likely, evaluated unfavorably or are less willing to take over a leadership role than their male counterparts. Because gender-fair language (e.g., feminine-masculine word pairs, German: ‘Geschäftsführerin/Geschäftsführer’, CEO, fem./CEO, masc.) leads to a higher mental inclusion of women compared to generic masculine forms (German: ‘Geschäftsführer’, CEO,masc.), we argue that masculine forms endorse the ‘lack of fit’ for women in leadership, whereas gender-fair language reduces it. Three studies support our assumption. Masculine forms led to a ‘lack of fit’ for women in leader selection: they were hired less likely (Study 1) and evaluated less favorably (Study 2) than their male counterparts. Moreover, women showed less willingness to apply when masculine forms were used in the advertisement for a leadership position. Contrary, no such gender-bias was obtained in case of gender-fair language.

Gender stereotypes and the attribution of leadership traits. A cross-cultural comparison

In this study, we analyzed cultural variations of managerial gender typing, that is, that managers are perceived as possessing traits that are part of the masculine stereotype. Management students of both sexes from three different countries—Australia, Germany, and India—estimated the percentage to which one of three stimulus groups, that is, executives-in-general (no gender specification), male executives, or female executives, possesses person-orientedand task-oriented leadership traits. Participants also rated the importance of these characteristics for the respective group. Furthermore, another group of participants described themselves regarding the two types of traits and their importance for themselves. Altogether, the results indicate a less traditional view of leadership compared to previous findings, which is very similar in all three countries. Nevertheless, there exists an interculturally shared view of a female-specific leadership competence according to which women possess a higher person orientation than men. The self-descriptions of the female and male management students regarding person- and task-oriented traits were found to be very similar.

Meta-cognition about biological sex and gender-stereotypic physical appearance: Consequences for the assessment of leadership competence

Previous findings are inconsistent with regard to whether men are judged as being more or less competent leaders than women. However, masculine-relative to feminine-looking persons seem to be judged consistently as more competent leaders. Can this different impact of biological sex and physical appearance be due to the disparate availability of meta-cognitive knowledge about both sources? The results of Study 1 indicated that individuals possess meta-cognitive knowledge about a possible biasing influence of persons’ biological sex, but not for their physical appearance. In Study 2, participants judged the leadership competence of a male versus female stimulus person with either masculine or feminine physical appearance. In addition, the available cognitive capacity was manipulated. When high capacity was available, participants corrected for the influence of stimulus persons’ sex, but they fell prey to this influence under cognitive load. However, the effect of physical appearance was not moderated by cognitive capacity.

The Beauty and the Beast. A Tale of Democratic Crises and Globalization

There are two competing hypotheses concerning the connection between democracy and globalization. The critics hold globalization responsible for an ongoing crisis of democracy. The enthusiasts highlight the positive contributions of financial openness and international political cooperation on the development of democracy. In this contribution the author investigates the interrelation between globalization and the quality of established democracies. He introduces the Democracy Barometer, a new instrument that measures the quality of democracy in 30 established democratic regimes between 1995 and 2005 and that explicitly does not measure sustainable government because it aims at serving as dependent as well as independent variable to explain different economic, societal and natural environment, i.e. sustainable development. Based on this instrument, the author first shows that one cannot speak of an ongoing crisis of (established) democracies. Second, he also conducts several multilevel analyses to model the different developments of the quality of democracy in the different countries. The author then shows that economy, i.e. economic globalization indeed has a positive impact on the quality of democracy. However, this impact is stronger in stable, i.e. older than in younger established democracies. Further investigations show that a high quality of democracy also goes hand in hand with societal and environmental performance.

Impact of a stress coping strategy on perceived stress levels and performance during a simulated cardiopulmonary resuscitation: a randomized controlled trial

Background Cardiopulmonary resuscitation (CPR) causes significant stress, which may cause deficiencies in attention and increase distractibility. This may lead to misjudgements of priorities and delays in CPR performance, which may further increase mental stress (vicious cycle). This study assessed the impact of a task-focusing strategy on perceived stress levels and performance during a simulated CPR scenario. Methods This prospective, randomized-controlled trial was conducted at the simulator-center of the University Hospital Basel, Switzerland. A total of 124 volunteer medical students were randomized to receive a 10 minute instruction to cope with stress by loudly posing two taskfocusing questions (“what is the patient’s condition?”, “what immediate action is needed?”) when feeling overwhelmed by stress (intervention group) or a control group. The primary outcome was the perceived levels of stress and feeling overwhelmed (stress/overload); secondary outcomes were hands-on time, time to start CPR and number of leadership statements. Results Participants in the intervention group reported significantly less stress/overload levels compared to the control group (mean difference: -0.6 (95%CI −1.3, -0.1), p=0.04). Higher stress/overload was associated with less hands-on time. Leadership statements did not differ between groups, but the number of leadership statements did relate to performance. Hands-on time was longer in the intervention- group, but the difference was not statistically different (difference 5.5 (95%CI −3.1, 14.2), p=0.2); there were no differences in time to start CPR (difference −1.4 (95%CI −8.4, 5.7), p=0.71). Conclusions A brief stress-coping strategy moderately decreased perceived stress without significantly affecting performance in a simulated CPR. Further studies should investigate more intense interventions for reducing stress.

A closer look beneath the surface: Various facets of the think-manager-think-male stereotype

Previous research has indicated that successful managers are perceived as possessing characteristics that belong to a global masculine stereotype. This study was designed to compare the gender-stereotypical perception of leadership by investigating global and leadership-specific gender stereotypes and contrasting self-perception and the perceptionby others. Descriptive and prescriptive norms were analyzed and abilities studied in a leadership context. The sample consists of 215 management students, and the results indicate an impact of gender stereotypes on the perception of leadership by women and men. Ratings of the importance of leadership characteristics yielded a less gender-stereotypic view, especially by female participants. In their self-evaluations women and men did not differ in the degree in which they possess person- and task-oriented skills. They also did not differ in their ratings of the importance of possessing these skills themselves. Finally, women reported that they possess task-oriented abilities more seldom than such abilities were attributed to leaders-in-general.
