Prozac Leadership and the limits of positive thinking
No full textThis article critically examines excessive positivity in leadership dynamics. It argues that the tendency for leader positivity to become excessive is a recurrent but under-researched medium through which power and identity can be enacted in leadership dynamics. Drawing on the metaphor of ‘Prozac’, it suggests that leaders’ excessive positivity is often characterized by a reluctance to consider alternative voices, which can leave organizations and societies ill-prepared to deal with unexpected events. Prozac leadership encourages leaders to believe their own narratives that everything is going well and discourages followers from raising problems or admitting mistakes. The article also argues that followers (broadly defined) are often quick to identify leaders’ excessive positivity and are likely to respond through various forms of resistance. It concludes by considering the extent to which excessive positivity also characterizes leadership studies, and raises additional questions for further critical analyses of Prozac leadership
In search of the perfect manager? Work-life balance and managerial work
No full textWork-life balance debates continue to proliferate but give relatively little critical attention to managerial workers. This article draws on research into the experiences of managers in a local government organization revealing an intricate, multifaceted and heterogeneous picture of fragmentation, conflicting demands, pressures and anxieties. The study highlights the importance of paid work for public sector managers; the concomitant difficulties in controlling working hours for those in managerial roles and the extent to which shifts in work orientation occur during managers’ careers. Research findings suggest that in practice work-life balance initiatives may only serve to increase managerial anxieties and pressures, the very opposite outcome to that intended. These themes do not feature in many work-life balance debates, which tend to assume the perfect manager who is able and willing to create a symmetrical balance between different spheres of life

Maternal cardiac function in early pregnancies with high uterine artery resistance
No full textOBJECTIVE: To compare the maternal cardiac function and serum concentration of cardiac troponin T (cTnT) and N-terminal pro-B-type natriuretic peptide (NT-proBNP) in first-trimester patients, according to uterine artery Doppler velocimetry (UADV).
METHODS: This cross-sectional study included singleton pregnancies with normal UADV (n=17) and abnormal UADV (n=19). Maternal echocardiography was performed and blood samples were taken at 11-14 weeks. Echocardiographic parameters included: (a) left ventricular (LV) long axis velocities; (b) atrial size; (c) LV filling pressure; (d) the ratio of peak mitral flow velocity in early diastole and early mitral annular diastolic velocity (E/Ea ratio); and (e) the E/flow propagation velocity ratio. The maternal serum concentrations of cTnT and NT-proBNP were determined by sensitive and specific immunoassays. RESULTS: Patients with abnormal UADV had higher estimated left ventricular filling pressure (P=0.004), higher E/Ea ratio (P=0.03), higher E/flow propagation ratio (P=0.02), and lower LV long axis velocity (P=0.02) than those with normal UADV. There were no significant differences in the maternal serum concentration of cTnT or NT-proBNP.
CONCLUSIONS: Patients with abnormal UADV in the first trimester have higher left ventricular filling pressure and may have left ventricular systolic dysfunction
Community recovery capital and how it contributes to building recovery capital at the individual level
No full textAlthough personal and social capital will be discussed in depth in some of the preceding chapters, the notion of community capital has received less attention than personal and social capital and this chapter will examine the origins of the concept and some of the innovative methods used to measure it. This chapter will include Asset Based Community Development (Kretzmann and McKnight, 1993), training and development of community connectors (McKnight and Block, 2010), and Asset Based Community Engagement (Collinson and Best, 2019). The chapter will explore the value of engagement with a range of community resources (otherwise known as assets) available to support individuals on their recovery journeys in the form of professional services (including but not restricted to drug and alcohol treatment and support), peer-led and mutual aid groups, education, employment and training opportunities, as well as sports, recreation, and arts. Two models for recognising the role of community capital – Recovery Oriented Systems of Care (ROSC) and Inclusive Recovery Cities (IRC) will also be described through the lens of community capital, with consideration of how recovery communities and the broader community can reciprocally strengthen one another. However, the chapter will close by discussing not only the assets but the related notions of accessibility and engagement, and the challenges associated with the measurement of community assets and resources within a recovery capital model moving forward.

Blended leadership: employee perspectives on effective leadership in the UK further education sector
No full textThis article explores employee perspectives on effective leader ship in UK Further Education (FE). Studies on leader ship effectiveness typically seek either to specify the individual qualities of ‘heroic’ leaders or, increasingly, to highlight the collective nature of ‘post-heroic’ leader ship. While these discourses are frequently seen as dichotomous and competing, our research found that FE employees often value practices that combine elements of both. They tended to prefer subtle and versatile practices that we term ‘blended leader ship’; an approach that values, for example, both delegation and direction, both proximity and distance and both internal and external engagement. Drawing on other studies which indicate that paradoxical blends of apparently irreconcilable opposites might form the basis for effective leader ship, the article considers the implications of this analysis for the study of Higher Education (HE). It concludes by highlighting the potential value of more dialectical approaches to the theory and practice of leadership
Communities of leadership in FE
No full textThis working paper highlights the significance of multiple communities as crucial conditions, processes and consequences of FE leadership. Our research suggests that in (almost) all their activities FE colleges engage communities. They make important, but frequently under-estimated contributions to the local community and economy. This is the case within colleges (e.g. students and employees), between colleges and their multiple-partners (e.g. in the local community and economy) and between different colleges (e.g. professional networks and associations between Principals). The paper argues that in the FE sector communities and leadership are inextricably-linked, sometimes in mutually-reinforcing, but also in potentially contradictory ways. These communities are not only both internal and external to colleges themselves, they are also multiple and diverse, frequently shifting, interacting and impacting in complex, simultaneous ways. Our working paper: 1. Outlines (some of) the multiple communities served by FE colleges. In particular, we explore the FE college as: a learning community, a socially inclusive community, an inclusive learning community and a provider of adult and community learning. 2. Examines some of the important challenges for those occupying FE leadership positions in seeking to engage with these multiple communities. Our research findings suggest that on-going attempts to engage diverse communities constitute a crucial challenge for effective FE leadership. 3. Suggests a different way of understanding the nature of FE leadership. This indicates that a ‘blended leadership’ (Collinson and Collinson 2005c) approach may be particularly effective in engaging multiple, shifting communities in sustainable ways. 4. Suggests that the community contribution of FE colleges is frequently neglected and/or under-estimated. Many of the staff we have interviewed argue that important aspects of colleges’ community engagements remain invisible or undervalued, particularly by those who evaluate per
