    This thesis investigates victims' access to justice in Trinidad and Tobago, using their own narratives. It seeks to capture how their experiences affected their identities as victims and citizens, alongside their perceptions of legitimacy regarding the criminal justice system. While there have been some reforms in the administration of criminal justice in Trinidad and Tobago, such reforms have not focused on victims' accessibility to the justice system. Using grounded theory methodology, qualitative data was collected through 31 in-depth interviews with victims and victim advocates. The analysis found that victims experienced interpersonal, structural, and systemic barriers at varying levels throughout the criminal justice system, which manifested as institutionalized secondary victimization, silencing and inequality. This thesis argues that such experiences not only served to appropriate conflict but demonstrates that access is often given in a very narrow sense. Furthermore, it shows a failure to encompass access to justice as appropriated conflicts are left to stagnate in the system as there is often very little resolution. Adopting a postcolonial lens to analyse victims' experiences, the analysis identified othering practices that served to institutionalize the vulnerability and powerlessness associated with victim identities. Here, it is argued that these othering practices also affected the rights consciousness of victims, delegitimating their identities as citizens. Moreover, as a result of their experiences, victims had mixed perceptions of the justice system. It is argued that while the system is a legitimate authority victims' endorsement of the system is questionable, therefore victims' experiences suggest that there is a reinforcement of the system's legal hegemony. The findings suggest that within the legal system of Trinidad and Tobago, legacies of colonialism shape the postcolonial present as the psychology and inequalities of the past are present in the interactions and processes of justice. These findings are relevant for policymakers in Trinidad and Tobago and other regions. From this study it is recognized that, to improve access to justice for victims, there needs to be a move towards victim empowerment that promotes resilience and enhances social capital. Going forward it is noted that there is a need for further research

    The Professional Identity of Doctors who Provide Abortions: A Sociological Investigation

    Get PDF
    Abortion is a medicalised problem in England and Wales, where the law places doctors at the centre of legal provision and puts doctors in control of who has an abortion. However, the sex-selection abortion scandal of 2012 presented a very real threat to 'abortion doctors', when the medical profession's values and practices were questioned in the media, society and by Members of Parliament. Doctors found themselves at the centre of a series of claims that stated doctors were acting both illegally and unethically, driven by profit rather than patient needs. Yet, the perspectives of those doctors who provide abortions has been under-researched; this thesis aims to fill that gap by examining the beliefs and values of this group of doctors. Early chapters highlight the ambiguous position of the abortion provider in Britain, where doctors are seen as a collective group of professionals motivated by medical dominance and medical autonomy. They outline how this position is then questioned and contested, with doctors being presented as unethical. By studying abortion at the macro-, meso- and micro-levels, this thesis seeks to better understand the values of the 'abortion doctor', and how these levels shape the work and experiences of abortion providers in England and Wales. This thesis thus addresses the question: 'What do abortion doctors' accounts of their professional work suggest about the contemporary dynamics of the medicalisation of abortion in Britain?'. It investigates the research question using a qualitative methodological approach: face-to-face and telephone interviews were conducted with 47 doctors who provide abortions in England and Wales. The findings from this empirical study show how doctors' values are linked to how they view the 'normalisation of abortion'. At the macro-level doctors, openly resisted the medicalisation of abortion through the position ascribed to them by the legal framework, yet at the meso-level doctors construct an identity where normalising abortion is based on further medicalising services. Finally, at the micro-level, the ambiguous position of the abortion provider is further identified in terms of being both a proud provider and a stigmatised individual. This thesis shows that while the existing medicalisation literature has some utility, it has limited explanatory power when investigating the problem of abortion. The thesis thus provides some innovative insights into the relevance and value of medicalisation through a comprehensive study on doctors' values, beliefs and practices

    Underwater optical wireless communications in turbulent conditions: from simulation to experimentation

    Get PDF
    Underwater optical wireless communication (UOWC) is a technology that aims to apply high speed optical wireless communication (OWC) techniques to the underwater channel. UOWC has the potential to provide high speed links over relatively short distances as part of a hybrid underwater network, along with radio frequency (RF) and underwater acoustic communications (UAC) technologies. However, there are some difficulties involved in developing a reliable UOWC link, namely, the complexity of the channel. The main focus throughout this thesis is to develop a greater understanding of the effects of the UOWC channel, especially underwater turbulence. This understanding is developed from basic theory through to simulation and experimental studies in order to gain a holistic understanding of turbulence in the UOWC channel. This thesis first presents a method of modelling optical underwater turbulence through simulation that allows it to be examined in conjunction with absorption and scattering. In a stationary channel, this turbulence induced scattering is shown to cause and increase both spatial and temporal spreading at the receiver plane. It is also demonstrated using the technique presented that the relative impact of turbulence on a received signal is lower in a highly scattering channel, showing an in-built resilience of these channels. Received intensity distributions are presented confirming that fluctuations in received power from this method follow the commonly used Log-Normal fading model. The impact of turbulence - as measured using this new modelling framework - on link performance, in terms of maximum achievable data rate and bit error rate is equally investigated. Following that, experimental studies comparing both the relative impact of turbulence induced scattering on coherent and non-coherent light propagating through water and the relative impact of turbulence in different water conditions are presented. It is shown that the scintillation index increases with increasing temperature inhomogeneity in the underwater channel. These results indicate that a light beam from a non-coherent source has a greater resilience to temperature inhomogeneity induced turbulence effect in an underwater channel. These results will help researchers in simulating realistic channel conditions when modelling a light emitting diode (LED) based intensity modulation with direct detection (IM/DD) UOWC link. Finally, a comparison of different modulation schemes in still and turbulent water conditions is presented. Using an underwater channel emulator, it is shown that pulse position modulation (PPM) and subcarrier intensity modulation (SIM) have an inherent resilience to turbulence induced fading with SIM achieving higher data rates under all conditions. The signal processing technique termed pair-wise coding (PWC) is applied to SIM in underwater optical wireless communications for the first time. The performance of PWC is compared with the, state-of-the-art, bit and power loading optimisation algorithm. Using PWC, a maximum data rate of 5.2 Gbps is achieved in still water conditions

    The labour supply and retirement of older workers: an empirical analysis

    Get PDF
    This thesis examines the labour supply of older workers, their movement into retirement, and any movement out of retirement and back into work. In particular the labour force participation, labour supply and wage elasticity and other income elasticity of work hours are estimated for older workers and compared to younger workers. The thesis goes on to look at the movement into retirement for older workers as a whole by examining cohorts by gender, wave and age. The thesis also presents a descriptive and quantitative • examination of the changes in income and happiness that occur as an individual retires. Finally the thesis examines the reasons why an individual may return to work from v . retirement. The results of the findings suggest: that younger workers are significantly more responsive to wage and household income changes than older worker

    Recent Hong Kong cinema and the generic role of film noir in relation to the politics of identity and difference

    Get PDF
    This thesis identifies a connection in Hong Kong cinema with classical Hollywood film noir and examines what it will call a 'reinvestment' in film noir in recent films. It will show that this reinvestment is a discursive strategy that both engages the spectator-subject in the cinematic practice and disengages him or her from the hegemony of the discourse by decentring the narrative. The thesis argues that a cinematic practice has occurred in the recent reinvestment of film noir in Hong Kong, which restages the intertextual relay of the historical genre that gives rise to an expectation of ideas about social instability. The noir vision that is seen as related to the fixed categories of film narratives, characterizations and visual styles is reassessed in the course of the thesis using Derridian theory. The focus of analysis is the way in which the constitution of meanings is dependent on generic characteristics that are different. Key to the phenomenon is a film strategy that destabilizes, differs and defers the interpretation of crises-personal, social, political and/or cultural-by soliciting self-conscious re-reading of suffering, evil, fate, chance and fortune. It will be argued that such a strategy evokes the genre expectation as the film invokes a network of ideas regarding a world perceived by the audience in association with the noirish moods of claustrophobia, paranoia, despair and nihilism. The noir vision is thus mutated and transformed when the film device differs and defers the conception of the crises as tragic in nature by exposing the workings of the genre amalgamation and the ideological function of the cinematic discourse. Thus, noirishness becomes both an affect and an agent that contrives a self-reflexive re-reading of the tragic vision and of the conventional comprehension of reality within the discursive practice. The film strategy, as an agent that problematizes the film form and narrative, gives rise to what I call a politics of difference, which may also be understood as the Lyotardian 'language game' or a practice of 'pastiche' in Jameson's terminology. Under the influence of the film strategy, the spectator is enabled to negotiate his or her understanding of recent Hong Kong cinema diegetically and extra-diegetically by traversing different positions of cinematic identification. When the practice of genre amalgamation adopts the visual impact of the noirish film form, the film turns itself into a playing field of 'fatal' misrecognition or a site of question. Through cinematic identification and alienation from the identification, the spectator-subject is enabled to experience the misrecognition as the film slowly foregrounds the way in which the viewer's presence is implicated in the narrative. This thesis demonstrates that certain contemporary Hong Kong films introduce this selfconscious mode of explication and interpretation, which solicits the spectator to negotiate his or her subject-position in the course of viewing. The notions of identity and subjectivity under scrutiny will thus be reread. With reference to The Private Eye Blue, Swordsman II, City a/Glass and Happy Together, the thesis shall explore the ways in which the Hong Kong films enable and facilitate a negotiation of cultural identity

    Adaptive task selection using threshold-based techniques in dynamic sensor networks

    Get PDF
    Sensor nodes, like many social insect species, exist in harsh environments in large groups, yet possess very limited amount of resources. Lasting for as long as possible, and fulfilling the network purposes are the ultimate goals of sensor networks. However, these goals are inherently contradictory. Nature can be a great source of inspiration for mankind to find methods to achieve both extended survival, and effective operation. This work aims at applying the threshold-based action selection mechanisms inspired from insect societies to perform action selection within sensor nodes. The effect of this micro-model on the macro-behaviour of the network is studied in terms of durability and task performance quality. Generally, this is an example of using bio-inspiration to achieve adaptivity in sensor networks

    Understanding the adoption and implementation of Sector Skills Councils in Chile

    Get PDF
    Technical and Vocational Education and Training (TVET) policies have gained increased interest in global agendas, being a particular concern in ensuring that youths have the skills needed to enter the labour market. In this line, international organisations and cooperation agencies have widely promoted sector skills bodies. This policy seeks to involve employers in skills formation and foster collaboration among different stakeholders to ensure that the skills developed through TVET meet labour market needs. However, academic research about this specific policy is limited. Moreover, even when several countries have adopted these bodies, little is known about them from a policy transfer perspective (i.e. studying the travel of an education policy from one place to another). This thesis addresses this gap by examining the adoption and implementation of private-led Sector Skills Councils (SSCs) in Chile. Thus, two main research questions guided this study: Why and how private actors in Chile have adopted SSCs? How have different employers and TVET providers implemented SSCs’ initiatives in Chile? This qualitative research utilised a multiple-case study design for which data was collected through semi-structured interviews and documents analysis. First, based on a Cultural Political Economy approach, the adoption of SSCs was investigated by examining the main factors that could account for the mechanisms involved in the process. Second, the implementation of SSCs was studied by considering a policy enactment focus and the principles of the Realist Evaluation approach to understand how two main actors affected by the policy, employers and TVET providers, have fulfilled the policy expectations. The findings of this thesis show the crucial role of ideational factors (i.e. the influence of policy entrepreneur) to trigger policy change and the specific economic, institutional, political and educational conditions at the national and sectoral levels that may explain the adoption of SSCs. As a result, it advances our understanding of the different roles played by ideational and material factors in adopting SSCs as a TVET policy. Likewise, given the unusual private-led adoption of these bodies, this study provides an empirical demonstration of this uncommon situation. Simultaneously, it offers potential new insights about the assessments made by employers and their business associations when deciding to involve in skill formation policies. Moreover, by investigating the implementation of SSCs from the perspective of the main actors expected to enact the policy, this thesis provides an initial understanding of the varied contextual and stakeholder conditions affecting these actors’ responses to SSCs. In doing so, this thesis also offers an empirical demonstration of the limitations of SSCs adopted and implemented with a skills supply orthodoxy rhetoric

    Theatre, performance and digital culture

    A thesis submitted to the University of Wolverhampton in partial fulfilment of the requirement of the degree of Doctor of Philosophy.This thesis proposes that the theory of aesthetic agency derived from gaming in digital culture may be used as a lens through which live theatre and performance may be analysed. I argue that the aesthetics, immersion and play with identity in live theatre and performance are informed by digital culture through the behaviour and agency of the participants, be they audience or participants. Using a grounded theory methodological approach, four large-scale outdoor immersive productions and two traditional theatrical productions have been selected to provide a comparative analysis using aesthetic agency. Aesthetic agency is central to the analysis of immersion and play with identity in the productions selected. Comprising intention, perceivable consequence, narrative potential, transformation, co-presence and presence aesthetic agency is the feeling of pleasure audience and participants derive through the experience of live theatre and performance. Analysis using aesthetic agency in immersive productions examines qualities such as interaction and participation, discovery, understanding social rules, proximity to points of engagement within the performance, the use of narrative or gameplay, liminality and the suspension of disbelief and the use of physical or imaginary boundaries. Aesthetic agency in play with identity uses qualities of transportation, presence and co-presence and is analysed using themes of liminality, ritual, agency and memory which offer the opportunity of real experience within the virtual environments. The outcomes of the study highlight the opportunities to analyse and understand the meaning making process in live theatre and performance in a new manner through the lens of aesthetic agency derived from digital culture. Through examples, the outcomes show how digital culture theory may be used in live theatre and performance to examine and explain the experience for spectators and participants. The future use of aesthetic agency as a dramaturgical tool then becomes a possibility which may enhance the development process and enrich the subsequent experience of spectators and participants. Further, aesthetic agency may find utility as a dramaturgical tool when used to aid the creation of new live productions
