Delivering the recommendations of the Fraud Review 2006 and the paradox of police leadership

The purpose of this context statement is to investigate those factors which either contributed towards or impeded delivery of key recommendations from the Fraud Review, Attorney General (2006). These public works comprise three independent but intrinsically linked projects; the National Fraud Reporting Centre (NFRC), National Fraud Intelligence Bureau (NFIB) and the Economic Crime Academy (ECA). Critical analysis shows how the success of each project influenced and contributed directly to the next project. Examination is made of how, without vision and the continuity of leadership, these public works would either not exist today or would have failed to be as successful as they are. Reflection upon this, together with analyses of individual and organisational leadership styles, stimulated two unavoidable and fundamental questions to be raised: What does the Police Service now stand for? Is the current model of police leadership fit for purpose? Critical analysis of the role of police leadership in the delivery of these public works led to a further, specific question: Is the police response to fraud appropriate? This is because police responses to fraud often appear to be in conflict with Peelian Principles, ACPO (2012) and are more biased towards serving the criminal justice system rather than delivering social justice through interventions that are morally and ethically grounded. On commencement of this context statement the intention was for it to be read by like-minded leaders and visionaries, those who do not fit the norm or stereotype of a typical police manager; as the context statement evolved so too has the intended readership. Throughout reflective assessment and consideration of police leadership and today’s performance culture, it became increasingly apparent that this subject should be core reading for police leaders of the future. However, on completion of the context statement, it is apparent that readership audience should extend beyond the Police Service and the policy makers within government and the Ministry of Justice. The real audience should be the public we serve, those with whose consent we police. Therefore, it seems logical that public should be the ultimate critical assessors of this contribution, together with the effectiveness and appropriateness of the current and ongoing culture of police leadership and the response to fraud

The Hopf Rings for KO and KU

We compute the mod two homology Hopf rings of the spectra KO and KU. The spaces in these spectra are the infinite classical groups and their coset spaces, and their homology was first calculated in the Cartan seminars, but the Hopf ring structure was first determined in the second author's unpublished PhD thesis. The presentation given here serves as an introduction to the first author's much more intricate work on the connective spectrum bo. The Hopf ring viewpoint turns out to be very convenient for understanding the homological effect of various maps between classical groups and fibrations of their connective covers.Comment: 20 pages; to appear in JPA

Thermalization and the chromo-Weibel instability

Despite the apparent success of ideal hydrodynamics in describing the elliptic flow data which have been produced at Brookhaven National Lab's Relativistic Heavy Ion Collider, one lingering question remains: is the use of ideal hydrodynamics at times t < 1 fm/c justified? In order to justify its use a method for rapidly producing isotropic thermal matter at RHIC energies is required. One of the chief obstacles to early isotropization/thermalization is the rapid longitudinal expansion of the matter during the earliest times after the initial nuclear impact. As a result of this expansion the parton distribution functions become locally anisotropic in momentum space. In contrast to locally isotropic plasmas anisotropic plasmas have a spectrum of soft unstable modes which are characterized by exponential growth of transverse chromo-magnetic/-electric fields at short times. This instability is the QCD analogue of the Weibel instability of QED. Parametrically the chromo-Weibel instability provides the fastest method for generation of soft background fields and dominates the short-time dynamics of the system.Comment: 8 pages, 4 figures, Invited plenary talk given at the 19th International Conference on Ultrarelativistic Nucleus-Nucleus Collisions: Quark Matter 2006 (QM 2006), Shanghai, China, 14-20 Nov 200

Planning assistance for the NASA 30/20 GHz program. Network control architecture study.

Network Control Architecture for a 30/20 GHz flight experiment system operating in the Time Division Multiple Access (TDMA) was studied. Architecture development, identification of processing functions, and performance requirements for the Master Control Station (MCS), diversity trunking stations, and Customer Premises Service (CPS) stations are covered. Preliminary hardware and software processing requirements as well as budgetary cost estimates for the network control system are given. For the trunking system control, areas covered include on board SS-TDMA switch organization, frame structure, acquisition and synchronization, channel assignment, fade detection and adaptive power control, on board oscillator control, and terrestrial network timing. For the CPS control, they include on board processing and adaptive forward error correction control

Matching pre-equilibrium dynamics and viscous hydrodynamics

We demonstrate how to match pre-equilibrium dynamics of a 0+1 dimensional quark gluon plasma to 2nd-order viscous hydrodynamical evolution. The matching allows us to specify the initial values of the energy density and shear tensor at the initial time of hydrodynamical evolution as a function of the lifetime of the pre-equilibrium period. We compare two models for the pre-equilibrium quark-gluon plasma, longitudinal free streaming and collisionally-broadened longitudinal expansion, and present analytic formulas which can be used to fix the necessary components of the energy-momentum tensor. The resulting dynamical models can be used to assess the effect of pre-equilibrium dynamics on quark-gluon plasma observables. Additionally, we investigate the dependence of entropy production on pre-equilibrium dynamics and discuss the limitations of the standard definitions of the non-equilibrium entropy.Comment: 24 pages, 5 figures,v2: minor modifications and updated references.

The impacts of tourism on two communities adjacent to the Kruger National Park, South Africa

This paper explores the socioeconomic impacts of tourism associated with the Kruger National Park, South Africa's flagship national park, on the neighbouring villages of Cork and Belfast. Case study research, where the study area was characterised as a social-ecological system, was used to investigate the impacts of Park tourism on these communities. The findings offer a micro-scale, local community perspective of these impacts and indicate that the enclave nature of Park tourism keeps local communities separate from the Park and makes it hard for them to benefit from it. The paper concludes with reflections on this perceived separation, and suggests the need to make the Park boundaries more 'permeable' so as to improve relationships with adjacent communities, while also pragmatically managing community expectation

Parameterisation and Efficient MCMC Estimation of Non-Gaussian State Space Models

The impact of parameterisation on the simulation efficiency of Bayesian Markov chain Monte Carlo (MCMC) algorithms for two non-Gaussian state space models is examined. Specifically, focus is given to particular forms of the stochastic conditional duration (SCD) model and the stochastic volatility (SV) model, with four alternative parameterisations of each model considered. A controlled experiment using simulated data reveals that relationships exist between the simulation efficiency of the MCMC sampler, the magnitudes of the population parameters and the particular parameterisation of the state space model. Results of an empirical analysis of two separate transaction data sets for the SCD model, as well as equity and exchange rate data sets for the SV model, are also reported. Both the simulation and empirical results reveal that substantial gains in simulation efficiency can be obtained from simple reparameterisations of both types of non-Gaussian state space models.Bayesian methodology, stochastic volatility, durations, non-centred in location, non-centred in scale, inefficiency factors.

Leadership Perspectives of Tennessee School Leaders

The problem was to determine factors Tennessee school leaders consider important to effective leadership. Organizational frames by Bolman and Deal were used. The four organizational frames used in the study were structural, human resource, political, and symbolic approaches to leadership. The frames were examined with regard to their relationship to Tennessee superintendent\u27s leadership and management styles with the perception of his/her style by their superordinates and subordinates. Leadership Orientations, a validated instrument designed by Bolman and Deal, was used to gain insight about school leader perceptions from superintendents and from individuals who work in school administration with the superintendents. Individual school systems, the director of the Tennessee Academy of School Leaders (TASL), the Tennessee Organization of School Superintendents (TOSS), and the Tennessee School Board Association (TSBA) received the data analysis results about leadership perspectives. The research provided school system personnel a method to understand individual, subordinate, and superordinate expectations as they relate to the four organizational frames. Additionally, the findings indicated predictors of management and leadership effectiveness as perceived by the respondents
