The effects of conflict in driving forward innovation in shared leadership management consultant teams

It is argued in this study that current investigations of the role of conflict in shared leadership teams and, thus, teams in which all members have the opportunity to participate in its decision-making process are insufficient as they have focused on the downsides of these conflicts. This study demonstrates that task conflict is beneficial in that it can have positive effects on innovation in teams. It shows that particularly in shared leadership management consultant teams task conflict can stimulate innovation. Therefore, this research investigates the relationships among shared leadership, conflict and innovation. The research develops and empirically tests a conceptual model which demonstrates the relationships between these concepts and for which the inclusion of multiple research methods was essential. The sequential explanatory approach included a combination of quantitative and qualitative methods, the order of which can be adapted for other domains of application. The conceptual model was first tested with a sample of 329 management consultants. This was followed by 25, in-depth, face-to-face interviews conducted with individual survey respondents. In addition, weekly meetings of a management consultant team in action were video recorded over several months. This allowed for an in-depth explanation of the findings from the survey by providing an understanding of the underlying processes. The inclusion of observational methods provided a validating role and explained how and why conflicts contributed to the development of team innovation, through the analysis of subtleties and fleeting disagreements in a real-life management consultant team. The results deliver an assessment of the theoretical model and demonstrate that task conflict can allow for additional innovation in management consultant teams operating under a shared leadership structure. A practical model and guidelines for management consultant teams wanting to enhance their innovatory capacities are provided. In addition, a novel-user methodology which includes video observations is developed, with recommendations and steps aiding researchers aiming to employ a similar combination of methods. An original contribution to knowledge is made regarding the positive effects that task conflict can have towards innovation in shared leadership teams. Collaboration and trust are identified as important mediators between shared leadership and task conflict and significant regarding the development of innovation. The effectiveness of shared leadership in reducing negative relationship conflict and the benefits of both shared leadership and task conflict in enhancing innovation are demonstrated.

Forward-in-Time, Spatially Explicit Modeling Software to Simulate Genetic Lineages Under Selection

SELECTOR is a software package for studying the evolution of multiallelic genes under balancing or positive selection while simulating complex evolutionary scenarios that integrate demographic growth and migration in a spatially explicit population framework. Parameters can be varied both in space and time to account for geographical, environmental, and cultural heterogeneity. SELECTOR can be used within an approximate Bayesian computation estimation framework. We first describe the principles of SELECTOR and validate the algorithms by comparing its outputs for simple models with theoretical expectations. Then, we show how it can be used to investigate genetic differentiation of loci under balancing selection in interconnected demes with spatially heterogeneous gene flow. We identify situations in which balancing selection reduces genetic differentiation between population groups compared with neutrality and explain conflicting outcomes observed for human leukocyte antigen loci. These results and three previously published applications demonstrate that SELECTOR is efficient and robust for building insight into human settlement history and evolution.

Market reforms and privatisation in the English National Health Service

The article examines developments in the marketisation and privatisation of the English National Health Service, primarily since 1997. It explores the use of competition and contracting out in ancillary services and the levering into public services of private finance for capital developments through the Private Finance Initiative. A substantial part of the article examines the repeated restructuring of the health service as a market in clinical services, initially as an internal market but subsequently as a market increasing opened up to private sector involvement. Some of the implications of market processes for NHS staff and for increased privatisation are discussed. The article examines one episode of popular resistance to these developments, namely the movement of opposition to the 2011 health and social care legislative proposals. The article concludes with a discussion of the implications of these system reforms for the founding principles of the NHS and the sustainability of the service.

Law and Original Contract in the Republican Thought of Immanuel Kant

This article discusses the concept of right and its identification with the power to coerce, to show a reciprocity between the original contract and the right, as a manifestation of the reciprocity between moral law and freedom, as Kant states in its Second Critique. The demonstration of this view will allow a republican stance evident in the legal and political thought of Kant, since the right of a people can only exist while the town itself is unified to enact.

Commentary on Milton's Contract 1667

The contract between the poet John Milton and the stationer Samuel Simmons, concerning the publication of Paradise Lost, is the earliest agreement between an author and a publisher for which there exists documentary evidence. The commentary suggests that, while the terms of the contract do not necessarily reveal anything substantive about how authors in the mid-seventeenth century understood the nature of the rights they had in their manuscript work, it is nevertheless significant. Since the early eighteenth century, Milton, his work, and his contract with Simmons, were all co-opted, in a variety of ways, to service contemporary debates about the status of the author, about author-publisher relations, and about the nature of the relationship between an author and his work within the context of the emerging copyright regime.

Rate Maximization of Decode-and-Forward Relaying Systems with RF Energy Harvesting

We consider a three-node decode-and-forward (DF) half-duplex relaying system, where the source first harvests RF energy from the relay, and then uses this energy to transmit information to the destination via the relay. We assume that the information transfer and wireless power transfer phases alternate over time in the same frequency band, and their time fraction (TF) may change or be fixed from one transmission epoch (fading state) to the next. For this system, we maximize the achievable average data rate. Thereby, we propose two schemes: (1) jointly optimal power and TF allocation, and (2) optimal power allocation with fixed TF. Due to the small amounts of harvested power at the source, the two schemes achieve similar information rates, but yield significant performance gains compared to a benchmark system with fixed power and fixed TF allocation.

Secure Multiple Amplify-and-Forward Relaying with Co-Channel Interference

We investigate the impact of co-channel interference on the security performance of multiple amplify-and-forward (AF) relaying networks, where N intermediate AF relays assist the data transmission from the source to the destination. The relays are corrupted by multiple co-channel interferers, and the information transmitted from the relays to destination can be overheard by the eavesdropper. In order to deal with the interference and wiretap, the best out of N relays is selected for security enhancement. To this end, we derive a novel lower bound on the secrecy outage probability (SOP), which is then utilized to present two best relay selection criteria, based on the instantaneous and statistical channel information of the interfering links. For these criteria and the conventional maxmin criterion, we quantify the impact of co-channel interference and relay selection by deriving the lower bound on the SOP. Furthermore, we derive the asymptotic SOP for each criterion, to explicitly reveal the impact of transmit power allocation among interferers on the secrecy performance, which offers valuable insights into practical design. We demonstrate that all selection criteria achieve full secrecy diversity order N, while the proposed in this paper two criteria outperform the conventional max-min scheme.
