The Leadership Quarterly: State of the journal

Abstract: The Leadership Quarterly has developed the reputation of being the custodian of the best multidisciplinary scientific research focusing on leadership. This reputation has been the result of the efforts of successive editorial teams who laid important foundations in building the journal (see joint article from former editors: Atwater, Mumford, Tosi, & Yammarino, 2014). We are passionate about scientific discovery and aspire to publish the best leadership research, on par with that of the top general journals. Thus, as current guardians of the journal's scientific record, we realize the enormous responsibility we have in shaping what is published and in signaling to the field what types of research we value. In this editorial, we discuss the importance afforded to leadership as a scientific discipline, take stock of the first two years of our term, explain the current editorial policy, and report on how the journal is doing and where it is heading.

Leader development begins at home: Overparenting harms adolescent leader emergence

Abstract: There is increasing interest in the early roots and influencing factors of leadership potential from a life span development perspective. This conceptual and empirical work extends traditional approaches focusing on adults in organizational settings. From the perspective of early influences on leader development, the goal of this study was to examine the effects of overparenting on adolescent leader emergence, influencing mechanisms, and sex differences. Students (N = 1,255) from 55 classrooms in 13 junior high schools participated, with additional responses from their parents, peers, and teachers. The results indicated that overparenting is negatively related to adolescent leader emergence as indicated by parent ratings, teacher ratings, and peer nominations in addition to leader role occupancy. The negative effects of overparenting on leader emergence (perceived and actual) were serially mediated by self-esteem and leader self-efficacy. In addition, sex difference analysis revealed that male adolescents received more overparenting and showed less leader emergence (perceived and actual) than female adolescents. Female adolescents' self-esteem was more likely to be negatively related to overparenting, and female adolescents' leader emergence (perceived and actual) was more strongly related to their leader self-efficacy when compared with male adolescents. Implications for life span leader development theory, for youth and adult leadership development practices, and for parenting practices on future generations are discussed.

A high-throughput energy-dispersive tender X-ray spectrometer for shot-to-shot sulfur measurements.

Abstract: An X-ray emission spectrometer that can detect the sulfur Kα emission lines with large throughput and a high energy resolution is presented. The instrument is based on a large d-spacing perfect Bragg analyzer that diffracts the sulfur Kα emission at close to backscattering angles. This facilitates the application of efficient concepts routinely employed in hard X-ray spectrometers towards the tender X-ray regime. The instrument described in this work is based on an energy-dispersive von Hamos geometry that is well suited for photon-in photon-out spectroscopy at X-ray free-electron laser and synchrotron sources. Comparison of its performance with previously used instrumentation is presented through measurements using sulfur-containing species performed at the LCLS. It is shown that the overall signal intensity is increased by a factor of ∼15. Implementation of this approach in the design of a tender X-ray spectroscopy endstation for LCLS-II is also discussed.

Bricoleurs extraordinaire: sports coaches in Inter War Britain

Abstract: In Inter-War Britain, several individuals exploited their athletic skills by pursuing careers as coaches, invariably drawing on, and reflecting on, their practical experiences, in a method theorised by John Dewey These coaches were the masters of a body of specialist craft knowledge, the tacit nature of which was transmitted through apprentices watching the experts in action Craft knowledge was never static, however, and coaches exemplified the notion of the ‘Bricoleur’ in constantly trialling emerging knowledge, intuitively accepting or rejecting appropriate material This paper explores how Inter-War practitioners utilised their coaching ‘toolbox’, using examples from newspaper reports, personal and public archives, and instructional texts The author chronicles some coaching lives and highlights the range of knowledge that coaches had at their command, well before the emergence of sports science and coach certification programmes The paper concludes by questioning assumptions that coaches can no longer rely on ‘learning the trade’ through experience
