The methods used by the UK Police to investigate complaints of rape have unsurprisingly come under much scrutiny in recent times, with a 2007 joint report on behalf of HM Crown Prosecution Service Inspectorate and HM Inspectorate of Constabulary concluding that there were many areas where improvements should be made. The research reported here forms part of a larger project which draws on various discourse analytical tools to identify the processes at work during police interviews with women reporting rape. Drawing on a corpus of video recorded police interviews with women reporting rape, this study applies a two pronged analysis to reveal the presence of these ideologies. Firstly, an analysis of the discourse markers ‘well’ and ‘so’ demonstrates the control exerted on the interaction by interviewing officers, as they attach importance to certain facts while omitting much of the information provided by the victim. Secondly, the interpretative repertoires relied upon by officers to ‘make sense’ of victim’s accounts are subject to scrutiny. As well as providing micro-level analyses which demonstrate processes of interactional control at the local level, the findings of these analyses can be shown to relate to a wider context – specifically prevailing ideologies about sexual violence in society as a whole.

A new challenge in the field of molecular magnetism is the design of optically and thermally switchable solid state magnetic materials for which various kinds of application may be feasible. Our research activities involve preparative methods, the study of the physical properties and associated mechanisms, as well as the exploration of further possibilities. Particular focus is on heterobimetallic Prussian Blue analogs, such as on RbMn[Fe(CN)6], in which the interplay between the two different adjacent metal ions is crucial for the observation of photo-induced phenomena. Our studies revealed that modification of the preparative conditions lead to differences in structural features that allowed tuning of the magnetic and electron transfer properties of RbxMn[Fe(CN)6]y.zH2O.

This thesis begins by examining the concepts of civil society and social capital. Specifically, it outlines the role of health and education third sector organisations (TSOs) in building civil society and generating social capital which is conducive to democratisation. Following this, the thesis presents literature on civil society development in the context of the Russian Federation, highlighting a void in our understanding of health and education TSOs in this context. The literature review examines cultural-historic antecedents and their impact on civil society development. These antecedents result in three constraints which limit TSOs ability to establish civil society as an autonomous space. In light of these constraints, the thesis explores the present day realities faced by Russian TSOs and proposes that the all-dominant nature of the Russian state leads to managed civil society arrangements. Consequently the thesis addresses the question of how a managed civil society manifests itself in the context of the Russian Federation. Using a qualitative research design, the thesis investigates the control mechanisms created by legislative framework, the ability of third sector organisations to substitute for the state, and the organisational characteristics of TSOs within a managed civil society space. Based on interview data from 82 TSOs across three geographical regions, the empirical chapters explore these three aspects in-depth. Firstly, the thesis demonstrates how a specific legislative framework is used as a legally mandated method to manage civil society. Secondly, the thesis explores more subtle attempts by the state to manage civil society. And thirdly, the thesis highlights ways in which the state controls TSOs and coerces them to mimic marionette organisations. Overall, the evidence presented throughout the thesis highlights the idiosyncratic nature of managed civil society arrangements in Russia in which the state is able to control and direct civil society

In construction projects, the aim of project control is to ensure projects finish on time, within budget, and achieve other project objectives. During the last few decades, numerous project control methods have been developed and adopted by project managers in practice. However, many existing methods focus on describing what the processes and tasks of project control are; not on how these tasks should be conducted. There is also a potential gap between principles that underly these methods and project control practice. As a result, time and cost overruns are still common in construction projects, partly attributable to deficiencies of existing project control methods and difficulties in implementing them. This paper describes a new project cost and time control model, the project control and inhibiting factors management (PCIM) model, developed through a study involving extensive interaction with construction practitioners in the UK, which better reflects the real needs of project managers. A set of good practice checklist is also developed to facilitate implementation of the model. © 2013 American Society of Civil Engineers.

This thesis is an evaluation of practices to control antibiotic prescribing in UK NHS hospitals. Within the past ten years there has been increasing international concern about escalating antibiotic resistance, and the UK has issued several policy documents for pmdent antibiotic prescribing. Chief Pharmacists in 253 UK NHS hospitals were surveyed about the availability and nature of documents to control antibiotic prescribing (formularies, policies and guidelines), and the role of pharmacists and medical microbiologists in monitoring prescribers' compliance with the recommendations of such documents. Although 235 hospitals had at least one document, only 60% had both an antibiotic formulary and guidelines, and only about one-half planned an annual revision of document(s). Pharmacists were reported as mostly checking antibiotic prescribing on every ward whilst medical microbiologists mostly visited selected units only. Response to a similar questionnaire was obtained from the Chief Medical Microbiologists in 131 UK NHS hospitals. Comparisons of the questionnaires indicated areas of apparent disagreement about the roles of pharmacists and medical microbiologists. Eighty three paired-responses received from pharmacists and medical microbiologists in the same hospital revealed poor agreement and awareness about controls. A total of 205 institutional prescribing guidelines were analysed for recommendations for the empirical antibiotic prescribing of Community-Acquired Pneumonia (CAP). Variation was observed in recommendations and agreement with national guidance from the British Thoracic Society (BTS). A questionnaire was subsequently sent to 235 Chief Pharmacists to investigate their awareness of this new guidance from the BTS, and subsequent revision of institutional guidelines. Documents had been revised in only about one-half of hospitals where pharmacists were aware of the new guidance. An audit of empirical antibiotic prescribing practices for CAP was performed at one hospital. Although problems were experienced with retrieval of medical records, diagnostic criteria were poorly recorded, and only 57% of prescribing for non-severe CAP was compliant with institutional guidelines. A survey of clinicians at the same hospital identified that almost one-half used the institutional guidelines and most found them useful. However, areas for improvement concernmg awareness of the guidelines and ease of access were identified. It is important that hospitals are equipped to react to changes in the hospital environment including frequent movement of junior doctors between institutions, the employment of specialist "infectious diseases pharmacists" and the increasing benefits offered by information technology. Recommendations for policy have been suggested.

The thesis provides an analysis of an occupation in the process of making itself a profession. The solicitors' profession in Birmingham underwent a great many changes during the 19th century against a background of industrialisation and urbanisation. The solicitors' conception of their status and role, in the face of these challenges, had implications for successful strategies of professionalisation. The increased prestige and power of the profession, and especially its elite, are examined in their social context rather than in terms of a technical process, or educational and organisational change. The thesis argues that -the profession's social relationships and broad concerns were significant in establishing solicitors as "professional men". In particular these are related to the profession's efforts to gain control of markets for legal services and increase social status. In the course of achieving these aims a concept of profession and a self-image were articulated by solicitors in order to persuade society and the state of the legitimacy of their claims. The concept of the gentlemanly professional was of critical importance in this instance. The successful creation of a provincial professional "community" by the end of the 19th century rested principally on a social and moral conception of professionalism rather than one which stressed specialised training and knowledge, professional organisations and credentials.

The open content creation process has proven itself to be a powerful and influential way of developing text-based content, as demonstrated by the success of Wikipedia and related sites. Distributed individuals independently edit, revise, or refine content, thereby creating knowledge artifacts of considerable breadth and quality. Our study explores the mechanisms that control and guide the content creation process and develops an understanding of open content governance. The repertory grid method is employed to systematically capture the experiences of individuals involved in the open content creation process and to determine the relative importance of the diverse control and guiding mechanisms. Our findings illustrate the important control and guiding mechanisms and highlight the multifaceted nature of open content governance. A range of governance mechanisms is discussed with regard to the varied levels of formality, the different loci of authority, and the diverse interaction environments involved. Limitations and opportunities for future research are provided.

The entorhinal cortex (EC) is a key brain area controlling both hippocampal input and output via neurones in layer II and layer V, respectively. It is also a pivotal area in the generation and propagation of epilepsies involving the temporal lobe. We have previously shown that within the network of the EC, neurones in layer V are subject to powerful synaptic excitation but weak inhibition, whereas the reverse is true in layer II. The deep layers are also highly susceptible to acutely provoked epileptogenesis. Considerable evidence now points to a role of spontaneous background synaptic activity in control of neuronal, and hence network, excitability. In the present article we describe results of studies where we have compared background release of the excitatory transmitter, glutamate, and the inhibitory transmitter, GABA, in the two layers, the role of this background release in the balance of excitability, and its control by presynaptic auto- and heteroreceptors on presynaptic terminals. © The Physiological Society 2004.

Although maximum power point tracking (MPPT) is crucial in the design of a wind power generation system, the necessary control strategies should also be considered for conditions that require a power reduction, called de-loading in this paper. A coordinated control scheme for a proposed current source converter (CSC) based DC wind energy conversion system is presented in this paper. This scheme combines coordinated control of the pitch angle, a DC load dumping chopper and the DC/DC converter, to quickly achieve wind farm de-loading. MATLAB/Simulink simulations and experiments are used to validate the purpose and effectiveness of the control scheme, both at the same power level. © 2013 IEEE.

We present data on the development a new type of optical fibre polariser and the characterisation of its wavelength properties. The device is fashioned using a two step process. Firstly, a standard UV long period grating (LPG) with a period of 330μm is inscribed into hydrogenated SMF-28, followed by femtosecond laser ablation of a groove parallel to the fibre axis. The UV inscribed LPGs have inherently low birefringence. However, the removal of the cladding layer parallel to the location of the LPG within the fibre core (as a result the ablation) modifies the cladding modes that couple with the LPG. Furthermore, the groove breaks the fibre symmetry introducing a non-uniform stress profile across the fibre cross section leading to significant birefringence. We show that increasing the depth of the groove increases the birefringence, and this behaviour coupled with the ability to control the wavelength location of the LPGs attenuations peaks results in a polariser able to operate at almost any wavelength and birefringence. The maximum birefringence reported here as polarisation mode splitting was approximately 39±0.1nm with a polarisation loss of 10dB. © 2011 Copyright Society of Photo-Optical Instrumentation Engineers (SPIE).
