The problems of offenders with mental disorders: A plurality of perspectives within a single mental health care organisation

Managers, doctors, nurses, occupational therapists, social workers, psychologists, unqualified staff and service users were interviewed for a qualitative study of risk management and rehabilitation in an inner city medium secure forensic mental health care unit. Different professional orientations to service user problems were identified. Doctors focused primarily on the diagnosis of mental disorder, which they managed mainly through pharmaceutical interventions. Psychologists were principally concerned with personal factors, for example service user insight into their biographical history. Occupational therapists concentrated mainly on daily living skills, and social workers on post-discharge living arrangements. Some front line nurses, held accountable for security lapses, adopted a criminogenic approach. Service users were more likely than professionals to understand their needs in terms of their wider life circumstances. These differences are explored qualitatively in relation to four models of crossdisciplinary relationships: monoprofessional self-organisation combined with restricted communication; hermeneutic reaching out to other perspectives; the establishment of interdisciplinary sub-systems; and transdisciplinary merger. Relationships between professions working in this unit, as portrayed in qualitative interviews, corresponded mainly to the first model of monoprofessional self-organisation. Reasons for restricted crossdisciplinary understanding, particularly the wide power/status differences between the medical and other professions, and between staff and patients, are discussed

Examining the health and well-being experiences of singers in popular music

This study investigated the health and well-being experiences of professional singers in popular music. Interpretative Phenomenological Analysis (IPA) of semi-structured interviews with five professional singers identified three main themes: (1) mental and physical experiences of health and support, (2) positive musical experiences and (3) barriers to health and well-being. Participants perceived health as important to their careers and viewed it as both physical and mental in nature. The singers relied on family and industry peers for support, whilst experiencing mental health challenges and physical health problems in the context of an emotionally intense landscape. Positive musical experiences involved the self-expression of songwriting, live music performance and relationships with fans, and barriers to health and well-being included touring, commercial challenges and a perceived lack of support. The findings suggest a need for increased awareness and understanding of the challenges faced by singers in popular music

Learning from the children : exploring preschool children's encounters with ICT at home

This paper is an account of our attempts to understand preschool children's experiences with information and communication technologies (ICT) at home. Using case study data, we focus on what we can learn from talking directly to the children that might otherwise have been overlooked and on describing and evaluating the methods we adopted to ensure that we maximised the children's contributions to the research. By paying attention to the children's perspectives we have learned that they are discriminating users of ICT who evaluate their own performances, know what gives them pleasure and who differentiate between operational competence and the substantive activities made possible by ICT

Who Draws the Line in El Paso, Texas: Multiscalar Interactions and the Chances for Border Reform

The question of how borders are defined and enforced has always been an important issue both to the state and to residents between whom make and must deal with those decisions. This project examines El Paso, Texas as a case study for shaping a more progressive future for border and immigration enforcement. It does so by reporting on 16 interviews with key actors in border policy discussions. El Paso offers an excellent opportunity to study how border and immigration enforcement approaches are negotiated between scales, including federal enforcement agencies, state government, city and county officials, and community activists. Immigration enforcement has been marked by massive increases in manpower, technology, and resources over the past 15 years, yet have failed to stem the tide of migration and resulted in the deaths of thousands of persons. This presents a particular challenge to border communities hosting both enforcers and undocumented migrants, and that are the main place where the impacts of border enforcement are felt, a challenge heightened by devolutionary movement of immigration enforcement to local actors. The project focuses particularly on the possibilities and challenges for community groups to harness the devolution of responsibility for immigration enforcement as a means of projecting border voices into the national debate. While still marginalized, it appears that the prospect for border involvement in progressive reform is strong

Dualization and deformations of the Bar-Natan—Russell skein module

This thesis studies the Bar-Natan skein module of the solid torus with a particular boundary curve system, and in particular a diagrammatic presentation of it due to Russell. This module has deep connections to topology and categorification: it is isomorphic to both the total homology of the (n,n)-Springer variety and the 0th Hochschild homology of the Khovanov arc ring H^n. We can also view the Bar-Natan--Russell skein module from a representation-theoretic viewpoint as an extension of the Frenkel--Khovanov graphical description of the Lusztig dual canonical basis of the nth tensor power of the fundamental U_q(sl_2)-representation. One of our primary results is to extend a dualization construction of Khovanov using Jones--Wenzl projectors from the Lusztig basis to the Russell basis. We also construct and explore several deformations of the Russell skein module. One deformation is a quantum deformation that arises from embedding the Russell skein module in a space that obeys Kauffman--Lins diagrammatic relations. Our quantum version recovers the original Russell space when q is specialized to -1 and carries a natural braid group action that recovers the symmetric group action of Russell and Tymoczko. We also present an equivariant deformation that arises from replacing the TQFT algebra A used in the construction of the rings H^n by the equivariant homology of the two-sphere with the standard action of U(2) and taking the 0th Hochschild homology of the resulting deformed arc rings. We show that the equivariant deformation has the expected rank. Finally, we consider the Khovanov two-functor F from the category of tangles. We show that it induces a surjection from the space of cobordisms of planar (2m, 2n)-tangles to the space of (H^m, H^n)-bimodule homomorphisms and give an explicit description of the kernel. We use our result to introduce a new quotient of the Russell skein module

Terahertz Time-Domain Magnetospectroscopy of a High-Mobility Two-Dimensional Electron Gas

We have observed cyclotron resonance in a high-mobility GaAs/AlGaAs two-dimensional electron gas by using the techniques of terahertz time-domain spectroscopy combined with magnetic fields. From this, we calculate the real and imaginary parts of the diagonal elements of the magnetoconductivity tensor, which in turn allows us to extract the concentration, effective mass, and scattering time of the electrons in the sample. We demonstrate the utility of ultrafast terahertz spectroscopy, which can recover the true linewidth of cyclotron resonance in a high-mobility ($>{10}^{6} \mathrm{cm^{2} V^{-1} s^{-1}}$) sample without being affected by the saturation effect.Comment: 4 pages, 3 figure
