On the pp-adic Langlands correspondence for algebraic tori

We extend the results by R.P. Langlands on representations of (connected) abelian algebraic groups. This is done by considering characters into any divisible abelian topological group. With this we can then prove what is known as the abelian case of the $p$-adic Langlands program.Comment: This was part of the authors Masters thesis and therefore has a somewhat expository nature. 22 pages.

Venezuela: The Shifting Organizational Framework for the Police

Recent political polarization in Venezuela has exacerbated longer term tensions over the organization and control of the police. Additionally, there is ongoing and widespread public dissatisfaction with the nature of policing. The patrimonial and authoritarian nature of much policing and the heterogeneity of training programs and resource provision pose considerable challenges to reform. Nevertheless, today’s police officers are right to wonder who they will be working for, what rank they will have, and what kind of work they will be given in 2018

Slopes of overconvergent Hilbert modular forms

We give an explicit description of the matrix associated to the $U_p$ operator acting on spaces of overconvergent Hilbert modular forms over totally real fields. Using this, we compute slopes for weights in the centre and near the boundary of weight space for certain real quadratic fields. \added[id=h]{Near the boundary of weight space we see that the slopes do not appear to be given by finite unions of arithmetic progressions but instead can be produced by a simple recipe from which we make a conjecture on the structure of slopes. We also prove a lower bound on the Newton polygon of the $U_p$.Comment: 22 pages, 7 figure, 7 tables. Final version, to appear in Experiment.

Hyperelastic modelling of nonlinear running surfaces

Accurate, 3-D analyses of running impact require a constitutive model of the running surface that includes the material nonlinearity shown by many modern surfaces. This paper describes a hyperelastic continuum that mimics the experimentally measured response of a particular treadmill surface. The material model sacrifices a little accuracy to admit a robust, low-order hyperelastic strain-energy functional. This helps prevent the premature termination of finite element simulations, due to numerical or material instabilities, that can occur with higher-order functionals. With only two free constants, it is also a more practical design tool. The best fit to the quasi-static response of the treadmill was achieved with an initial shear modulus =2 MPa and a power-stiffening index =25. The paper outlines the method used to derive the material constants for the treadmill, a device that is not amenable to the usual materials laboratory tests and must be reverse-engineered. Finite element analyses were then performed to ensure that the treadmill model interacts with the other components of the multibody running system in a numerically stable and physically realistic manner. The model surface was struck by a rigid heel, cushioned by a hyperfoam material that represents a shoe midsole. The results show that, while the ground reaction force is similar to that obtained with a rigid surface, the maximum principal stress in the shoe is reduced by 15%. Such a reduction, particularly when endured over many load cycles, may have a significant effect on comfort and damage to nearby tissue

El desempeño penal y el régimen abierto en las regiones Capital y Andina de Venezuela, 1981-2005. (Penal performance in open prisons in the Capital and Andean regions of Venezuela, 1981-2005.)

The penal performance of offenders assigned to halfway houses is examined for a sample of 1,253 residents between 1981 and 2005 in the Capital and Andean Regions of Venezuela. Contrary to the notion of progression outlined in prison legislation, only 12% of residents had been on work release prior to joining the halfway house, and residents had served an average of 55% of their sentence (considerably more than the 33% required by the guidelines). A request to revoke the assignment to the halfway house was filed in 34% of cases. The failure rate was significantly higher following the implementation of the Organic Criminal Procedure Code in 1999, and also showed marked variation between Community Treatment Centers

Prisiones e Internados: Una Comparación de los Establecimientos Penales en América del Norte y América Latina (Prisons and Internment: A Comparison of Penal Facilities in North America and Latin America)

The recent use of expressions such as “warehouse prison” in the U.S. and “concentration camp” in Latin America would seem to indicate that conditions of deprivation of freedom in both regions look more and more alike. The analysis presented here suggests that it is not so. Penal institutions in North and South America throughout six interrelated dimensions are compared: internal organization of the places, surveillance, isolation, supervision, administrative control and formalization of procedures. In North America, control is deep (persistent, intrusive and almost permanent); in Latin America, control is shallow (sporadic, indifferent and superficial). If in North America one speaks of prisons and incarceration, in Latin America it seems better to speak of judicial inmates and internment

2-adic slopes of Hilbert modular forms over Q(√5)

We show that for arithmetic weights with a fixed finite order character, the slopes of U_{p} for p = 2 (which is inert) acting on overconvergent Hilbert modular forms of level U_{0}(4) are independent of the (algebraic part of the) weight and can be obtained by a simple recipe from the classical slopes in parallel weight 3

Fighting for survival:patients' experiences of inpatient treatment for anorexia nervosa

This study investigates patients and ex-patients' experiences of inpatient treatment for Anorexia Nervosa (AN) across a variety of treatment locations and contexts. Adopting a social constructionist approach to grounded theory, data was collected through in-depth interview of 11 participants identified as white, cis-gender and female. This method enabled examination of the interactive processes and situational properties that influenced patients’ perceptions and the social processes that emerged from them. The core category ‘Fighting for Survival’ coheres two main categories that constitute the central findings of this study. Category A: ‘The Feeding Clinic –Embedding Anorexia’ and Category B: ‘Empowering the person – Fighting the ED’ reflect how participants accounts tended to present a split between positive and negative treatment experiences depending on how a service conceived the treatment objective and constructed the patient. These differences of context were found to generate vastly different interactive contexts and result in radically different treatment outcomes for a patient. Treatment contexts defined as ‘Feeding clinics’ were found to establish a social order amongst patients and staff defined by distrust and hostility. Perceiving treatment as a coercive regime, profound feelings of disempowerment and desperation lead patients to adopt strategies of resistance that ultimately appeared to entrench patients eating disordered behaviours and identity. Treatment contexts defined as ‘Person-Orientated’ by contrast were found to help patients (re)gain a sense of their inherent value as a person and to adopt a conceptual framework towards the ‘ED’ that provided both the reason and the means by which patients could begin the process of establishing a recovery position
