Preparing for the future:Challenges and opportunities for management and leadership skills

The development of effective leaders is essential for all healthcare professions and increasingly is becoming a key focus for the UK dental profession. There is comparatively little research about dental leadership in a UK context and the paper below should begin to help to redress the balance and to highlight areas for future consideration.
The aim of the study was to explore dental leaders’ perceptions of the current position of leadership in the dental profession and used a qualitative key informant study to do this. Three broad emergent themes are described and discussed - characteristics and behaviours of dental leaders; challenges for dental leaders; education and training for dental leadership. The findings show that whilst recognising that a lack of focus on leadership skills has caused problems in the past, current dental leaders are prepared to lead the profession forward. They view education at all levels as vital to this process and education for leadership at undergraduate level is perceived as an important way forward.

Deconstructing national leadership: Politicians’ accounts of electoral success and failure in the Irish Lisbon Treaty referenda

The Self Categorization approach to national leadership proposes that leaders rhetorically construct national identity as essentialized and inevitable in order to consensualize and mobilize the population. In contrast, discursive studies have demonstrated how national politicians flexibly construct the nation to manage their own accountability in local interactions, though this in turn has neglected broader leadership processes. The present paper brings both approaches together to examine how and when national politicians construct versions of national identity in order to account for their failure as well as success in mobilizing the electorate. Eight semi-structured conversational style interviews were conducted with a strategic sample of eight leading Irish politicians on the subject of the 2008/2009 Irish Lisbon Treaty referenda. Using a Critical Discourse Psychology approach, the hegemonic repertoire of the ‘settled will’
of the informed and consensualized Irish nation was identified across all interviews. Politicians either endorsed the ‘settled will’ repertoire as evidence of their successful leadership, or rejected the repertoire by denying the rationality or unity of the populace to account for their failure. Our results suggest national identity is only constructed as essentialized and inevitable to the extent that it serves a strategic political purpose.

Understanding leadership in local churches

A sociological examination of the concept of leadership and its application to understanding social interactions and power relations in local churches, based upon ethnographic investigation into London Methodist churches.

Autonomic management of non-functional concerns in distributed & parallel application programming

An approach to the management of non-functional concerns in massively parallel and/or distributed architectures that marries parallel programming patterns with autonomic computing is presented. The necessity and suitability of the adoption of autonomic techniques are evidenced. Issues arising in the implementation of autonomic managers taking care of multiple concerns and of coordination among hierarchies of such autonomic managers are discussed. Experimental results are presented that demonstrate the feasibility of the approach.

Responsible Leadership: Business Myth or Corporate Reality?

The financial crisis has highlighted some of the limitations of the global system. Enterprises previously thought to be too big to fail have learned the harsh realities of capitalism (Merill Lynch, Lehman Bros, Northern Rock), countries have been shaken considerably from the bankruptcy of Iceland to the near-collapse of the markets in Greece, Ireland and Italy. The current age of austerity has largely dominated supra-national and indeed global politics in the last few years. The extent of the crisis has illustrated that relationships between business, governments and society needs to be re-evaluated in light of shifts in the global market thereby recognizing that some countries have a more limited power of persuasion than some corporations.

Targeting distributed systems in FastFlow

FastFlow is a structured parallel programming framework targeting shared memory multi-core architectures. In this paper we introduce a FastFlow extension aimed at supporting also a network of multi-core workstations. The extension supports the execution of FastFlow programs by coordinating-in a structured way-the fine grain parallel activities running on a single workstation. We discuss the design and the implementation of this extension presenting preliminary experimental results validating it on state-of-the-art networked multi-core nodes. © 2013 Springer-Verlag.

Dynamical characteristics of solitary waves, shocks and envelope modes in kappa-distributed non-thermal plasmas: an overview

Space plasmas provide abundant evidence of highly energetic particle population, resulting in a long-tailed non-Maxwellian distribution. Furthermore, the first stages in the evolution of plasmas produced during laser-matter interaction are dominated by nonthermal electrons, as confirmed by experimental observation and computer simulations. This phenomenon is efficiently modelled via a kappa-type distribution. We present an overview, from first principles, of the effect of superthermality on the characteristics of electrostatic plasma waves. We rely on a fluid model for ion-acoustic excitations, employing a kappa distribution function to model excess superthermality of the electron distribution. Focusing on nonlinear excitations (solitons), in the form of solitary waves (pulses), shocks and envelope solitons, and employing standard methodological tools of nonlinear plasmadynamical analysis, we discuss the role of excess superthermality in their propagation dynamics (existence laws, stability profile), geometric characteristics and stability. Numerical simulations are employed to confirm theoretical predictions, namely in terms of the stability of electrostatic pulses, as well as the modulational stability profile of bright- and dark-type envelope solitons.
