The Character X Factor in Selecting Leaders: Beyond Ethics, Virtues, and Values

Leading with character requires a person to maintain a delicate balance of certain traits and understand the tensions which exist between humility and conviction, reluctance and courage, and vulnerability and integrity. A true leader must look beyond the content of a problem and rather examine the context of his or her individual make-up in relationship to themselves as well as to their surroundings

Tackling labour market exclusion of homeless people: the role of social enterprise

The aim of this thesis is to examine whether social enterprise provides employment and enterprise opportunities for homeless people. The homelessness literature has paid little attention to this changing policy landscape. This thesis seeks to contribute to the academic literature on homelessness and social enterprise and explores the ways in which social enterprise meets the employment and enterprise needs of homeless people. The research for this thesis focused on homelessness social enterprises based in England. The approach was guided by the critical realist method and included the construction of a database, multiple case study organisations, and interviews with homeless people and social enterprise leaders. An observational element was also incorporated in the case study organisations and wider social enterprises operating in the homelessness field. The research found that labour market exclusion of homeless people usually occurs early on in the lifecycle and was embedded over time through individual, inter-personal and structural elements. As a response to this social problem the research uncovered a number of existing and emerging homelessness social enterprise models. Organisations adopting these approaches occupy different sectors of the economy and provide a wide variety of (predominately service sector) jobs. The evidence also suggests they adopt different legal forms and use hybrid funding sources. Moreover, they cluster into particular types and most are not currently able to operate without the support of a host organisation. Instances of homelessness social enterprises were found to be increasing but clear challenges concerning their development came from exogenous economic and political factors. These developmental challenges were found to be buffered against by social elements endogenous to social enterprises. Also various advantages and disadvantages were related to each model, which critically highlighted that some approaches were better suited than others to assist homeless people into employment and enterprise, especially those experiencing ‘deep exclusion’ issues

Density scaling in viscous liquids: From relaxation times to four-point susceptibilities

We present numerical calculations of a four-point dynamic susceptibility, chi_4(t), for the Kob-Andersen Lennard-Jones mixture as a function of temperature T and density rho. Over a relevant range of T and rho, the full t-dependence of chi_4(t) and thus the maximum in chi_4(t), which is proportional to the dynamic correlation volume, are invariant for state points for which the scaling variable rho^gamma/T is constant. The value of the material constant gamma is the same as that which superposes the relaxation time, tau, of the system versus rho^gamma/T. Thus, the dynamic correlation volume is directly related to tau for any thermodynamic condition in the regime where density scaling holds. Finally, we examine the conditions under which the density scaling properties are related to the existence of strong correlations between pressure and energy fluctuations.Comment: 5 pages, 4 figures, updated reference

Distributions of inherent structure energies during aging

We perform extensive simulations of a binary mixture Lennard-Jones system subjected to a temperature jump in order to study the time evolution of fluctuations during aging. Analyzing data from 1500 different aging realizations, we calculate distributions of inherent structure energies for different aging times and contrast them with equilibrium. We find that the distributions initially become narrower and then widen as the system equilibrates. For deep quenches, fluctuations in the glassy system differ significantly from those observed in equilibrium. Simulation results are partially captured by theoretical predictions only when the final temperature is higher than the mode coupling temperature.Comment: 5 pages, 4 figure
