The discursive turn in policy analysis and the validation of policy stories

This paper is concerned with the language of policy documents in the field of health care, and how ‘readings’ of such documents might be validated in the context of a narrative analysis. The substantive focus is on a comparative study of UK health policy documents (N=20) as produced by the various assemblies, governments and executives of England, Scotland, Wales and Northern Ireland during the period 2000-2009. Following an identification of some key characteristics of narrative structure the authors indicate how text-mining strategies allied with features of semantic and network analysis can be used to unravel the basic elements of policy stories and to facilitate the presentation of data in such a way that readers can verify the strengths (and weaknesses) of any given analysis – with regard to claims concerning, say, the presence, absence, or relative importance of key ideas and concepts. Readers can also ‘see’ how the different components of any one story might fit together, and to get a sense of what has been excluded from the narrative as well as what has been included, and thereby assess the reliability and validity of interpretations that have been placed upon the data.

Transonic aeroelastic simulation for instability searches and uncertainty analysis

In this paper the use of eigenvalue stability analysis of very large dimension aeroelastic numerical models arising from the exploitation of computational fluid dynamics is reviewed. A formulation based on a block reduction of the system Jacobian proves powerful to allow various numerical algorithms to be exploited, including frequency domain solvers, reconstruction of a term describing the fluid–structure interaction from the sparse data which incurs the main computational cost, and sampling to place the expensive samples where they are most needed. The stability formulation also allows non-deterministic analysis to be carried out very efficiently through the use of an approximate Newton solver. Finally, the system eigenvectors are exploited to produce nonlinear and parameterised reduced order models for computing limit cycle responses. The performance of the methods is illustrated with results from a number of academic and large dimension aircraft test cases.

Tongue-tied?: An Active Analysis of Brian Friel's Translations

This article has arisen from a research-led production of Translations by Brian Friel for Queen’s University’s Tyrone Guthrie Society in February 2010. Drawing partly on a review of the existing critical literature and also from questions left unresolved by a previous experience of directing the play, the production sought to address through ‘active analysis’ (Merlin 2001) a number of research questions relating to the embodied nature of the rehearsal process and the historicity of Friel’s play. The analysis invokes Bergson (1910), Lefebvre (1991) and Worthern (2006) in establishing a performative correlative for insightful but more literary studies by Connolly (1993), Lojek (1994) and McGrath (1989 & 1999). A detailed account of the rehearsal process helps reveal the extent to which the idea of failure of communication is embedded in the text and embodied in performance, while an experiment with the partial use of the Irish language casts further light on Friel’s extraordinary device of rendering two languages through the medium of one. The use of music to counterpoint, rather than underscore the action, together with an achronological sequence of projected historical images inspired by Andrews (1983) provided me as director a means to challenge the audience’s presuppositions about the play. The sense of palimpsest, of the layered histories, that this evoked also served to highlight Friel’s use of the wider stylistic palette of Anglo-Irish drama, revealing Translations as a forerunner for Stewart Parker’s more explicit formal experiments in Northern Star. In rehearsal and performance Friel’s place in the continuum of the Irish theatrical canon became clear, as stylistic allusions to O’Casey, Shaw, Wilde and Beckett were embodied by the actors on the rehearsal room floor.

Medical Students' views of a career in Geriatric Medicine; Multi-Centre Qualitative Analysis

Medical students frequently have negative preconceptions of a career in Geriatric Medicine. In ta qualitative analysis of the free text from 789 response from Medical students in Scotland and Northern Ireland, we show that clinical attachment seffectively challenge negative student views and more positive statements about future careers in Geriatric Medicine emerged at the end of the attachment.

Micromechanical analysis of cohesive granular materials using the discrete element method with an adhesive elasto-plastic contact model

An adhesive elasto-plastic contact model for the discrete element method with three dimensional non-spherical particles is proposed and investigated to achieve quantitative prediction of cohesive powder flowability. Simulations have been performed for uniaxial consolidation followed by unconfined compression to failure using this model. The model has been shown to be capable of predicting the experimental flow function (unconfined compressive strength vs. the prior consolidation stress) for a limestone powder which has been selected as a reference solid in the Europe wide PARDEM research network. Contact plasticity in the model is shown to affect the flowability significantly and is thus essential for producing satisfactory computations of the behaviour of a cohesive granular material. The model predicts a linear relationship between a normalized unconfined compressive strength and the product of coordination number and solid fraction. This linear relationship is in line with the Rumpf model for the tensile strength of particulate agglomerate. Even when the contact adhesion is forced to remain constant, the increasing unconfined strength arising from stress consolidation is still predicted, which has its origin in the contact plasticity leading to microstructural evolution of the coordination number. The filled porosity is predicted to increase as the contact adhesion increases. Under confined compression, the porosity reduces more gradually for the load-dependent adhesion compared to constant adhesion. It was found that the contribution of adhesive force to the limiting friction has a significant effect on the bulk unconfined strength. The results provide new insights and propose a micromechanical based measure for characterising the strength and flowability of cohesive granular materials. 

A systematic review and meta-analysis of the survival of non-feldspathic porcelain veneers over 5 and 10 years

PURPOSE: This systematic review aimed to report and explore the survival of dental veneers constructed from non-feldspathic porcelain over 5 and 10 years.

MATERIALS AND METHODS: A total of 4,294 articles were identified through a systematic search involving all databases in the Cochrane Library, MEDLINE (OVID), EMBASE, Web of Knowledge, specific journals (hand-search), conference proceedings, clinical trials registers, and collegiate contacts. Articles, abstracts, and gray literature were sought by two independent researchers. There were no language limitations. One hundred sixteen studies were identified for full-text assessment, with 10 included in the analysis (5 qualitative, 5 quantitative). Study characteristics and survival (Kaplan-Meier estimated cumulative survival and 95% confidence interval [CI]) were extracted or recalculated. A failed veneer was one which required an intervention that disrupted the original marginal integrity, had been partially or completely lost, or had lost retention more than twice. A meta-analysis and sensitivity analysis of Empress veneers was completed, with an assessment of statistical heterogeneity and publication bias. Clinical heterogeneity was explored for results of all veneering materials from included studies.

RESULTS: Within the 10 studies, veneers were fabricated with IPS Empress, IPS Empress 2, Cerinate, and Cerec computer-aided design/computer-assisted manufacture (CAD/CAM) materials VITA Mark I, VITA Mark II, Ivoclar ProCad. The meta-analysis showed the pooled estimate for Empress veneers to be 92.4% (95% CI: 89.8% to 95.0%) for 5-year survival and 66% to 94% (95% CI: 55% to 99%) for 10 years. Data regarding other non-feldspathic porcelain materials were lacking, with only a single study each reporting outcomes for Empress 2, Cerinate, and various Cerec porcelains over 5 years. The sensitivity analysis showed data from one study had an influencing and stabilizing effect on the 5-year pooled estimate.

CONCLUSION: The long-term outcome (> 5 years) of non-feldspathic porcelain veneers is sparsely reported in the literature. This systematic review indicates that the 5-year cumulative estimated survival for etchable non-feldspathic porcelain veneers is over 90%. Outcomes may prove clinically acceptable with time, but evidence remains lacking and the use of these materials for veneers remains experimental.

A systematic review and meta-analysis of the survival of feldspathic porcelain veneers over 5 and 10 years

PURPOSE: This systematic review reports on the survival of feldspathic porcelain veneers.

MATERIALS AND METHODS: The Cochrane Library, MEDLINE (OVID), Embase, Web of Knowledge, selected journals, clinical trials registers, and conference proceedings were searched independently by two reviewers. Academic colleagues were also contacted to identify relevant research. Inclusion criteria were human cohort studies (prospective and retrospective) and controlled trials assessing outcomes of feldspathic porcelain veneers in more than 15 patients and with at least some of the veneers in situ for 5 years. Of 4,294 articles identified, 116 studies underwent full-text screenings and 69 were further reviewed for eligibility. Of these, 11 were included in the qualitative analysis and 6 (5 cohorts) were included in meta-analyses. Estimated cumulative survival and standard error for each study were assessed and used for meta-, sensitivity, and post hoc analyses. The I2 statistic and the Cochran Q test and its associated P value were used to evaluate statistical heterogeneity, with a random-effects meta-analysis used when the P value for heterogeneity was less than .1. Galbraith, forest, and funnel plots explored heterogeneity, publication patterns, and small study biases.

RESULTS: The estimated cumulative survival for feldspathic porcelain veneers was 95.7% (95% confidence interval [CI]: 92.9% to 98.4%) at 5 years and ranged from 64% to 95% at 10 years across three studies. A post hoc meta-analysis indicated that the 10-year best estimate may approach 95.6% (95% CI: 93.8% to 97.5%). High levels of statistical heterogeneity were found.

CONCLUSIONS: When bonded to enamel substrate, feldspathic porcelain veneers have a very high 10-year survival rate that may approach 95%. Clinical heterogeneity is associated with differences in reported survival rates. Use of clinically relevant survival definitions and careful reporting of tooth characteristics, censorship, clustering, and precise results in future research would improve metaanalytic estimates and aid treatment decisions.

Integrative analysis of chemo-transcriptomic profiles for drug-feature specific gene expression signatures

One of the major challenges in systems biology is to understand the complex responses of a biological system to external perturbations or internal signalling depending on its biological conditions. Genome-wide transcriptomic profiling of cellular systems under various chemical perturbations allows the manifestation of certain features of the chemicals through their transcriptomic expression profiles. The insights obtained may help to establish the connections between human diseases, associated genes and therapeutic drugs. The main objective of this study was to systematically analyse cellular gene expression data under various drug treatments to elucidate drug-feature specific transcriptomic signatures. We first extracted drug-related information (drug features) from the collected textual description of DrugBank entries using text-mining techniques. A novel statistical method employing orthogonal least square learning was proposed to obtain drug-feature-specific signatures by integrating gene expression with DrugBank data. To obtain robust signatures from noisy input datasets, a stringent ensemble approach was applied with the combination of three techniques: resampling, leave-one-out cross validation, and aggregation. The validation experiments showed that the proposed method has the capacity of extracting biologically meaningful drug-feature-specific gene expression signatures. It was also shown that most of signature genes are connected with common hub genes by regulatory network analysis. The common hub genes were further shown to be related to general drug metabolism by Gene Ontology analysis. Each set of genes has relatively few interactions with other sets, indicating the modular nature of each signature and its drug-feature-specificity. Based on Gene Ontology analysis, we also found that each set of drug feature (DF)-specific genes were indeed enriched in biological processes related to the drug feature. The results of these experiments demonstrated the pot- ntial of the method for predicting certain features of new drugs using their transcriptomic profiles, providing a useful methodological framework and a valuable resource for drug development and characterization.

A Sociology for Other Animals: Analysis, advocacy, intervention

Sociology has come late to the field of Human Animal Studies (HAS), and such scholarship remains peripheral to the discipline. Early sociological interventions in the field were often informed by a critical perspective, in particular feminism but also Marxism and critical race studies. There have also been less critical routes taken, often using approaches such as actor-network theory and symbolic interactionism. These varied initiatives have made important contributions to the project of animalizing sociology and problematizing its legacies of human-exclusivity. As HAS expands and matures however, different kinds of study and different normative orientations have come increasingly into relations of tension in this eclectic field. This is particularly so when it comes to the ideological and ethical debates on appropriate human relations with other species, and on questions of whether and how scholarship might intervene to alter such relations. However, despite questioning contemporary social forms of human-animal relations and suggesting a need for change, the link between analysis and political strategy is uncertain. This paper maps the field of sociological animal studies through some examples of critical and mainstream approaches and considers their relation to advocacy. While those working in critical sociological traditions may appear to have a more certain political agenda, this article suggests that an analysis of 'how things are' does not always lead to a coherent position on 'what is to be done' in terms of social movement agendas or policy intervention. In addition, concepts deployed in advocacy such as rights, liberation and welfare are problematic when applied beyond the human. Even conceptions less entrenched in the liberal humanist tradition such as embodiment, care and vulnerability are difficult to operationalize. Despite complex and contested claims however, this paper suggests that there might also be possibilities for solidarity.

A critical narrative analysis of shared decision-making in acute, inpatient mental health care

Shared decision-making (SDM) is a high priority in healthcare policy and is complementary to the recovery philosophy in mental health care. This agenda has been operationalised within the Values-Based Practice (VBP) framework, which offers a theoretical and practical model to promote democratic interprofessional approaches to decision-making. However, these are limited by a lack of recognition of the implications of power implicit within the mental health system. This study considers issues of power within the context of decision-making and examines to what extent decisions about patients? care on acute in-patient wards are perceived to be shared. Focus groups were conducted with 46 mental health professionals, service users, and carers. The data were analysed using the framework of critical narrative analysis (CNA). The findings of the study suggested each group constructed different identity positions, which placed them as inside or outside of the decision-making process. This reflected their view of themselves as best placed to influence a decision on behalf of the service user. In conclusion, the discourse of VBP and SDM needs to take account of how differentials of power and the positioning of speakers affect the context in which decisions take place.

Difficulties generating self-compassion: An interpretative phenomenological analysis

The aim of the present study was to make an idiographic investigation about the difficulties that are encountered by people who self-identify as having difficulties with self-compassion. Although a growing number of studies have been carried out concerning the concept of self-compassion, most research designs were quantitative. Based on this gap, the current study expanded the scope to include a qualitative dimension of the recent literature on self-compassion and Interpretative Phenomenological Analysis (IPA) was adopted as methodological preference, which particularly monitors the lived experience of participants. In consequence of four in-depth semi-structured interviews, four super-ordinate themes emerged; the double-edged-sword: perfectionism, the flaws of compassion, the effects of a third person, and the advantages of self-criticism. In line with pre-existing research, these findings explored the reasons behind self-undermining behaviours and misconstructions about self-compassion, which are a barrier to gentle self-talk. Furthermore, unfavourable effects of the social environment prime participants to maladaptive perfectionism and excessive self-criticism, which are considered a success formula by the participants. This study's purpose is to present a detailed roadmap about the self-destructive journey of the people with low self-compassion. It will help researchers and clinicians to develop future interventions in order to cultivate kind and encouraging attitudes in self-critical people.

A critical analysis of Child and Adolescent Mental Health Services policy in England, 2000‐2015

Policy in Child and Adolescent Mental Health (CAMH) in England has undergone radical changes in the last 15 years, with far reaching implications for funding models, access to services and service delivery. Using corpus analysis and critical discourse analysis, we explore how childhood, mental health, and CAMHS are constituted in 15 policy documents, 9 pre‐2010, and 6 post 2010. We trace how these constructions have changed over time, and consider the practice implications of these changes. We identify how children’s distress is individualised, through medicalising discourses and shifting understandings of the relationship between socioeconomic context and mental health. This is evidenced in a shift from seeing children’s mental health challenges as produced by social and economic inequities, to a view that children’s mental health must be addressed early to prevent future socio‐economic burden. We consider the implications CAMHS policies for the relationship between children, families, mental health services and the state. The paper concludes by exploring how concepts of ‘parity of esteem’ and ‘stigma reduction’ may inadvertently exacerbate the individualisation of children’s mental health.

Spirituality and Basketball Fanship: An Interpretative Phenomenological Analysis and Synthesis

The world of competitive sport affords an individual the opportunity to enter a spiritual community adding meaning that transcends one’s current understanding of life (Parry et al. 2007). Previously established dimensions of sports fanship (group affiliation, psychological commitment and team identification) share characteristics commonly associated with religious or spiritual affiliation indicating that fans may generate substantial life meaning from observing sporting encounters. In the present study, 12 male basketball fans (M=32.42; SD=7.97) completed semi-structured interviews immediately prior to viewing a competitive match at the 2011 European Basketball Championships (Vilnius, Lithuania). Interviews were structured under four headings; 1) the most memorable moment as a basketball fan, 2) thoughts, feelings and emotions attached to their team, 3) affiliation to the team in the context of the fan’s meaning of life, 4) connection with members of the fan’s sporting community. Interpretative Phenomenological Analysis was employed to analyse interview transcripts. Raw data clustered into four dimensions; 1) devotion, 2) obscure emotions, 3) connectedness, and 4) universal values. The results indicate that sports fanship is characterised by, and synonymous with, an established understanding of spirituality derived from membership of wider spiritual and/or religious communities. The findings hold implications for the marketing and membership of local, amateur and professional sports clubs and brands, as well as community development, health and welfare.
