The dynamics of institutional discourse : an intercultural perspective

Sarangi, Srikant K. January 1990 (has links)
The present study is an attempt to understand migrant workers' language behaviour in the Native Speaker-Non-Native Speaker (NS-NNS) contact situation. More specifically, it examines face-to-face encounters between first generation Asian migrants and British bureaucrats in two institutional settings - selection interviews and social service encounters. The data source mainly consists of transcripts of video-recordings of actual interactions. Structurally, as well as thematically, the thesis broadly falls into three parts. Part I (chapters 1-4) provides a background to the study and covers the sociocultural dimensions of the migrant situation; the linguistic environment surrounding the migrant workers; a sociological perspective on their interaction with British bureaucrats in institutional settings; and finally, a brief account of the methodological choices made for data acquisition and data treatment. Part II (chapters 5-8) constitutes the core of the thesis and presents an in-depth analysis of migrant workers' participation in institutional discourse involving British bureaucrats. In pointing out that in the institutional setting, language behaviour is necessarily context-specific, this part goes further and seeks various ways of explaining mismatches in the NS-NNS contact situation. It raises the fundamental question: are these mismatches always caused by non-native speakers' culturally determined discourse styles? The main focus here is on the problematic character of various interpretative and explanatory frameworks with particular reference to the NS-NNS contact situation. In this part of the thesis, theoretical premises underlying the pragmatics of "communication in context" - namely, activity types and prototypes - are reassessed in order to account adequately for the dynamic nature of institutional discourse. The two major arguments are as follows: firstly, all activity types are not sealed categories and therefore the fuzzy edges which differentiate one activity type from another need to be given attention in our analytical frameworks; and secondly, because the same discourse routines can occur within different activity types, there is a need to highlight the differential functions that such discourse routines are seen as serving in different activity types. Part III (chapters 9-11) stresses the need to recognise the wider societal context - NS-NNS discourse as asymmetrical communication and NS-NNS discourse as intercultural communication - in order to examine the relationship between participants' perceptions and the occurrence of "misinterpretation". As a conclusion, chapter 12 suggests that, rather than rely on radically distinct analytical frameworks for examining "migrant speech" and thereby in fact reinforcing cultural and linguistic stereotypes, NS-NNS discourse should be studied along the same lines as other kinds of discourse.

Counterfactual, prevention and causal thinking about workplace slip and trip accidents : a study of safety professionals, managers and accident subjects

Lehane, Paul Michael January 2015 (has links)
Counterfactual thinking typically follows an unexpected event and involves the mental simulation of an alternative outcome which can be either better or worse than the original one. In general, exceptional and controllable events are selected for change over those that are routine and uncontrollable, and actions are likely to be changed over inactions. Importantly an individual’s social role is thought to be critical in determining what is changed and how. Counterfactual thoughts have been associated with causal thinking and more recently with missed opportunities to prevent an unwanted outcome. Accidents at work are unwanted outcomes and are likely to generate counterfactual thoughts. As slips and trips continue to cause a significant number of injuries they are the focus of this research. Safety Professionals, Managers and Accident Subjects are most commonly involved in accident investigations and the study asks whether their different social roles or the type of accident influences how they use counterfactual, prevention and causal thoughts. 612 respondents were recruited representing Safety Professionals, Managers and Accident Subjects. After reading a slip or trip scenario they completed a counterfactual, prevention and causal sentence and these were analysed against 14 structural dimensions, seven of which were used for the first time in this study. The respondent’s job group and the type of accident were found to influence certain structural dimensions of the counterfactual, prevention and causal thoughts more than others. The respondent’s job group strongly influenced counterfactual direction, and the addition or subtraction of antecedents based on actions or inactions, whilst the type of accident strongly influenced the temporal location of the antecedent. Norm Theory (Kahneman & Miller, 1986) proposed that exceptional antecedents were selected for counterfactual change and a categorisation of types of exceptional events has been developed and applied in this study. The implications of these types of thoughts by Safety Professionals, Managers and Accident Subjects are considered.

"Don't let them see a drink in my hand" : an interpretative phenomenological analysis of British Sikh women's experiences of alcohol

Gill, Ravinder January 2015 (has links)
Despite alcohol consumption being prohibited within the Sikh community for religious reasons, it is well documented that this ruling is regularly transgressed. There is also now a rising body of evidence that suggests that there is an increase in consumption levels within this community (Wilsnack, Vogeltanz, Wilsnack and Harris, 2000; Heim, Hunter, Ross, Bakshi, Davies, Flatley and Meer, 2004; Brar and Moneta, 2009; Pannu, Zaman, Bhala, Zaman, 2009; Motune, 2011). It has been reported that female alcohol consumption has increased within the general population, with the Office of National Statistics (2011) reporting a 7.7% increase in alcohol unit consumption per week for women since 2008. There are also concerns about increased consumption amongst Sikh females and the prevalence of secret drinking behaviour amongst second generation British Sikh females (Bayley and Hurcombe, 2010; Motune, 2011). Increased consumption amongst females remains a cause for concern with the Institute of Alcohol Studies (2013) reporting that female drinking behaviour remains at historically high levels especially amongst young females. This research study aimed to explore the experiences of British Sikh women with alcohol. In the current research 6 British born Sikh women were interviewed and the interviews were analysed using Interpretative Phenomenological Analysis. Semi structured interviews were used to explore the young women’s experiences with alcohol; the methodological approach of Interpretative Phenomenological Analysis (IPA) allowed for a rich and detailed exploration of a taboo subject. Themes emerged relating to the nature of secret drinking behaviour including details of the lengths young women go in order to hide their drinking behaviour from their families. The interviews highlighted the participants’ experiences of being British and fitting in with society whilst maintaining their cultural identity as Sikh women. The interviews also revealed a major element of upholding a public image to wider society as well hiding their drinking behaviour from parents and other family members. The participants engaged in constant renegotiating between what is traditional and what is modern: "who am I?" vs. "who am I supposed to be?" The findings from this research can contribute to the development of culturally sensitive alcohol assessment measures and development of culturally sensitive alcohol treatment programmes.

Power relations in advocacy approaches in family group conferencing with children and young people

Fox, Darrell James January 2015 (has links)
Independent advocacy to support children and young people undertaking a Family Group Conference (FGC) is commonplace in England and Wales. This approach is viewed as good practice when working with young people in promoting their rights, agency, and participation in statutory social work meetings and processes where decisions are being undertaken that directly affect them. FGC provides a forum that allows statutory social workers to work in partnership with children and families where there are identified welfare concerns. However, the use of advocacy approaches within the FGC model researched in this study differs from the successful original processes developed in New Zealand. The study uses interviews with FGC participants, both users and practitioners, and an analysis of legislative and policy documents. It suggests that adapting the FGC model by changing its core processes of advocacy and coordination has had a variety of consequences, many unforeseen and negative as well as positive and affirming for young people and their families. The study found that empowerment, collaboration, and participation, all major precepts and objectives for FGC and advocacy approaches, were at times disrupted and diffused. This undermined rather than enhanced the experiences and the outcomes for service users with many feeling disempowered rather than empowered through the process. Hence the exercise of power through the processes of FGC Advocacy is held up to critical scrutiny and its impact both positive and negative on the FGC participants is discussed in depth.

Online support and domestic violence : negotiating discourses, emotions, and actions

Berg, Karin January 2015 (has links)
This thesis makes an original contribution to the study of online support on domestic violence (often referred to as online support communities/groups) through a discursive feminist perspective. Whilst the few previous studies on the topic are limited in scope, this is the first to adopt a mixed methods approach, exploring the topic through three sets of data from one online support forum on domestic violence: qualitative textual analysis of threads (n=215); an online survey (n=70); and two interviews with the manager of the forum and the moderator. The thesis aims to explore the role of an online support forum for women in the process of ending violence in their lives. Six aspects of online support are explored: forum-host’s goals, history and development of the forum; the experience of online support from the perspective of its members; exploring the themes and topics dealt with in the forum; how forum users perceive the impact and relevance of these themes; how members construct emotions, violence, victims and perpetrators in written postings; and how members use violence discourse in support processes. The analysis of these aspects provides a new body of evidence regarding the possibilities of online support groups. First, interviews with the forum hosts give a unique insight to the challenges with hosting the forum, pursuing moderation, and the limits and possibilities with using a public anonymous space. Second, through the survey, a sample of forum-members describes an eclectic form of mutual support, the experience of moderator’s work, and the interaction with other members. The forum's impact on participants’ understanding of violence, help-seeking and decision-making is measured. Third, the analysis of threads demonstrates in-depth members’ reflexive work (Giddens, 1991) in the forum, which comprehends the whole processes of ending violence, and shows how members use violence discourse to understand violence, manage emotions and encourage specific choices and actions. A discursive theoretical perspective explicates how support processes are enacted within and according to a normative practice. The findings suggest previously overlooked issues, in particular with regard to flexible long-term support for women with experiences of domestic violence (Kelly et al, 2014).

Adolescents' views of the electronic cigarette : a new gateway to addiction?

Clarke, Tilean Naomi January 2015 (has links)
Background: In the UK alone it is estimated that there are 2.1 million adult electronic cigarette (e-cigarette) users (Action on Smoking and Health, 2014). Introduced to the UK in 2006, ecigarette use has grown rapidly from 700,000 users in 2012 (Kmietowicz, 2014). Given that smoking initiation begins for the most part during adolescence, it is debatable as to whether the e-cigarette could be a gateway into addiction for adolescent non-smokers. This study examined awareness and use of the e-cigarette amongst adolescents, exploring factors that could lead to willingness to try the e-cigarette and susceptibility to smoking conventional cigarettes. Method: Using a between-participants survey design, power analysis calculated a sample size of at least 103 for medium effect. Exceeding this, 256 adolescent pupils aged 16 to 19 years consented to take part in the study. Survey data was collected in November 2013, during a series of 45-minute workshops held during school time. Data was analysed using chi-squared analysis and hierarchical multiple regression. RESULTS: Nearly all participants had heard of the e-cigarette (94.5%), with friends/family (49.2%) being the most frequently named source of information, followed by television (35.2%). Of the sample 14.5% had used an e-cigarette. Participants were more willing to try flavoured as opposed to the unflavoured version. Smoking status significantly predicted over a third of the variance of willingness to try an e-cigarette (F(1,254) = 141.81, p < .05) and a further 7.8% of the variance was significantly predicted by a positive prototype of a smoker and a negative prototype of an e-cigarette user (R² change = .078, F (8,246) = 4.27, p < 0.05). Willingness to try an e-cigarette was a significant predictor of susceptibility to use of an e-cigarette in the next year (F (1,253) = 174.71, p < .05) and smoking in the next year, in non-smokers (F(1,190) = 60.34, p < .05). Conclusion: Findings illustrated high levels of e-cigarette awareness among adolescents in a London, UK population. Use, whilst at low levels, had increased from the 10% reported in 2012 by Action on Smoking and Health (2014). Willingness to try an e-cigarette was associated with use susceptibility in the next year for both e-cigarettes and conventional cigarettes. This could be interpreted as a gateway effect, in terms of adolescents inclined to use e-cigarettes and then switch to conventional cigarettes (Bell and Keane, 2014). Future research using longitudinal methodologies would enable researchers to track the trend in e-cigarette use over time, observing whether e-cigarettes are truly serving as a gateway to addiction for other forms of nicotine products. Furthermore, prevention efforts to minimise smoking in youths should educate them about e-cigarette use as a cessation aid for smokers.

British domestic violence perpetrator programmes : 'programme integrity' within 'service integrity'

Phillips, Ruth January 2015 (has links)
Despite its stated importance to outcome evaluations, ‘programme integrity’ has long been lamented as a lacuna in the literature, especially in relation to domestic violence perpetrator programmes (DVPPs). Indeed, the literature reveals a lack of clarity regarding programme integrity in any context, although a baseline definition recognises its role as being to ensure programmes are delivered as intended and with a high level of efficacy. A ‘dominant definition’ emerges which is premised on programmes being subject to experimental models of development and evaluation and thus requiring strict adherence to a manual. This study draws on interviews with British DVPP pioneers, current practitioners and a case study, to explore how programme integrity is understood and practised in British DVPPs. The study finds that the dominant definition is inadequate to capture the practise of DVPPs due to their ‘process-driven’ approach which relies upon a high level of reflexivity, responsivity, and innovation. Furthermore, DVPPs require a concept of programme integrity – directly related to group-work delivery – which is embedded within a wider ‘service integrity’ which recognises the ways in which all aspects of the DVPP service contribute to integrity. The Respect Accreditation Standard requires that the work of the whole service is taken into account but this ‘whole service approach’ has not always translated into a ‘whole service ethos’ since the men’s group-work aspect of the service is often given prominence in terms of resources and status. Thus, a concept of ‘service integrity’ is presented which builds on the Accreditation Standard and encourages a culture, or ‘whole service ethos’, that properly recognises and addresses the contributions of the whole service to achieve an intervention which is effective and innovative, and has ‘integrity’.

Risky youth or gang members? : a contextual critique of the (re)discovery of gangs in Britain

Young, Tara January 2016 (has links)
The aim of this body of work has been to explore the anti-social behaviour and criminality of disaffected young people. In particular, my focus has been on how the perception of young offenders as ‘youth at risk’ needing guidance has metamorphosed into one of ‘gang’ membership requiring a punitive response. My work examines how community agencies and the criminal justice system have responded to this shift and focuses on the consequences for young people. Theoretically, this body of work has been influenced by a constructionist epistemology and incorporates a feminist methodology. The research work upon which this body of work rests consists mainly of qualitative research with marginalised young people, family members and practitioners working with them. My findings, detailed in various publications, have challenged assumptions about anti-social youngsters, the nature of collective offending by young people and the role the family plays in ‘gang-related’ offending. Most notably, they have sought to shape academic and political discourse in Britain by adopting a critical position against the prevailing view that ‘gang-related’ offending is the primary driver for the rise in violent offences. The work has contributed to the conceptualisation of ‘gang’ groups as they exist in contemporary Britain. It has influenced public policy on the gang, particularly in relation to defining the gang, on crime control and it has rerouted the debate about the involvement of girls and young women in street-based groups.
