In defining what he termed 'Television's Second Golden Age', Robert J.Thompson refers to characteristics such as being 'not regular TV', internal continuity, mixed genres but an aspiration towards 'realism', complex writing, self-consciousness and intertextuality. Such characteristics are displayed by the BBC series Life on Mars (2006-2007) which intermingles the Seventies tough cop show with psychological fantasy. This chapter examines the way that the series can be understood as a dramatisation of the negotiation that the creators undertook with their Seventies source material to update it for the values and qualities of contemporary television drama. It will emphasise the importance of television in the generation of the imagined 1973 and its characters, but also as an ongoing connection between the real and the imagined within the programme, including forming a breach of the boundaries between the two. Sam's actions within his Seventies world to remake it to include his own ideas of justice and due process while retaining the passion and freedom of action that the milieu provides will also be be examined in relation to the series' creators' needs to remake the Seventies tough-cop show in the light of modern social and media mores. The paper will also consider how Sam has to come to terms with his father's crimes, as the series' creators had to come to terms with the 'crimes' of taste, morality and approach of their 'parent' programmes from the Seventies' Golden Age.

Current conceptual models of reciprocal interactions linking soil structure, plants and arbuscular mycorrhizal fungi emphasise positive feedbacks among the components of the system. However, dynamical systems with high dimensionality and several positive feedbacks (i.e. mutualism) are prone to instability. Further, organisms such as arbuscular mycorrhizal fungi (AMF) are obligate biotrophs of plants and are considered major biological agents in soil aggregate stabilization. With these considerations in mind, we developed dynamical models of soil ecosystems that reflect the main features of current conceptual models and empirical data, especially positive feedbacks and linear interactions among plants, AMF and the component of soil structure dependent on aggregates. We found that systems become increasingly unstable the more positive effects with Type I functional response (i.e., the growth rate of a mutualist is modified by the density of its partner through linear proportionality) are added to the model, to the point that increasing the realism of models by adding linear effects produces the most unstable systems. The present theoretical analysis thus offers a framework for modelling and suggests new directions for experimental studies on the interrelationship between soil structure, plants and AMF. Non-linearity in functional responses, spatial and temporal heterogeneity, and indirect effects can be invoked on a theoretical basis and experimentally tested in laboratory and field experiments in order to account for and buffer the local instability of the simplest of current scenarios. This first model presented here may generate interest in more explicitly representing the role of biota in soil physical structure, a phenomenon that is typically viewed in a more process- and management-focused context.

Background: There are many issues regarding the use of real patients in objective structured clinical examinations (OSCEs). In dermatology OSCE stations, standardised patients (SPs) with clinical photographs are often used. Temporary transfer tattoos can potentially simulate skin lesions when applied to an SP. This study aims to appraise the use of temporary malignant melanoma tattoos within an OSCE framework. Method: Within an 11-station OSCE, a temporary malignant melanoma tattoo was developed and applied to SPs in a 'skin lesion' OSCE station. A questionnaire captured the opinions of the candidate, SP and examiners, and the degree of perceived realism of each station was determined. Standard post hoc OSCE analysis determined the psychometric reliability of the stations. Results: The response rates were 95.9 per cent of candidates and 100 per cent of the examiners and SPs. The 'skin lesion' station achieved the highest realism score compared with other stations: 89.0 per cent of candidates felt that the skin lesion appeared realistic; only 28 per cent of candidates had ever seen a melanoma before in training. The psychometric performance of the melanoma station was comparable with, and in many instances better than, other OSCE stations. Discussion: Transfer tattoo technology facilitates a realistic dermatology OSCE station encounter. Temporary tattoos, alongside trained SPs, provide an authentic, standardised and reliable experience, allowing the assessment of integrated dermatology clinical skills.

We investigate the violation of local realism in Bell tests involving homodyne measurements performed on multimode continuous-variable states. By binning the measurement outcomes in an appropriate way, we prove that the Mermin-Klyshko inequality can be violated by an amount that grows exponentially with the number of modes. Furthermore, the maximum violation allowed by quantum mechanics can be attained for any number of modes, albeit requiring a quantum state whose generation is hardly practicable. Interestingly, this exponential increase of the violation holds true even for simpler states, such as multipartite GHZ states. The resulting benefit of using more modes is shown to be significant in practical multipartite Bell tests by analyzing the increase of the robustness to noise with the number of modes. In view of the high efficiency achievable with homodyne detection, our results thus open a possible way to feasible loophole-free Bell tests that are robust to experimental imperfections. We provide an explicit example of a three-mode state (a superposition of coherent states) which results in a significantly high violation of the Mermin-Klyshko inequality (around 10%) with homodyne measurements.

Background and purpose
The dominant psychometric discourse of OSCEs may lead to unexpected problems, such as a checklist-based student performance1 which under emphasises the clinical relationship with student and standardised patient (SP). Such encounters can be dehumanising for SPs2 and have implications for what students learn about relational skills through the assessment process. In this study we explore medical students’ experiences of undertaking OSCEs using a phenomenological frame.
Methodology
Interpretative phenomenological analysis is a form of qualitative methodology which has strong resonance with existentialism and focuses on the lived experience without significant reference to external political or discursive
forces.
Six 4th year undergraduate medical students from Queen’s University Belfast were recruited in December 2013. Maximum variation sampling was used. Students were interviewed by a researcher in the week prior to the
OSCE and then again in the week following the OSCE in Jan 2014. Interviews were minimally structured in order to be open to respondents, rather than adhering to a fixed topic guide, but focussed on participants’ experiences, thoughts and feelings about taking part in OSCEs. Interviews were audio-recorded and
transcribed. Students were also asked to complete a short diary entry in the days prior to the OSCEs and another immediately following. Diary entries were written, emailed or audio-recorded at student’s preference.
Results
Transcripts are currently being analysed by interpretative phenomenological analysis. Preliminary analysis has demonstrated the significance of students’ relationships within the OSCE triad (student, SP and examiner); the effect of the immediate examination environment; realism versus roleplay; students’ perceptions of the purpose of assessment; and coping mechanisms.
Full results will be available by the time of the conference.
Conclusion and Discussion
Understanding the student experience in OSCEs is a crucial step in understanding the complex construction of relationships within the OSCE triad. The focus in OSCEs is typically on standardisation and reliability, but in exploring social interactions we may refocus attention on their inherent potential for learning and effects on both students and patients.

This paper examines the applicability of an immersive virtual reality (VR) system to the process of organizational learning in a manufacturing context. The work focuses on the extent to which realism has to be represented in a simulated product build scenario in order to give the user an effective learning experience for an assembly task. Current technologies allow the visualization and manipulation of objects in VR systems but physical behaviors such as contact between objects and the effects of gravity are not commonly represented in off the shelf simulation solutions and the computational power required to facilitate these functions remains a challenge. This work demonstrates how physical behaviors can be coded and represented through the development of more effective mechanisms for the computer aided design (CAD) and VR interface.

This paper studies the representation of suburbs as a place of anguish in the “Special Police” novels (Fleuve Noir publisher, Paris) by Frédéric Dard. This anxiety, it is argued, is what lends this collection of 25 novels some of their essential qualities, their unhealthy climate and absolute darkness. Dard’s suburbs fit into the traditions of realism; but the atmosphere, characters and plots owe to the American hardboiled school and like in film noir, space is stylized and dramatized, and often used to express a judgment of moral nature. Spatial representations in these novels are part of a critique of civilization and constitute a comment on the social modernization and public intervention in the development of the French territory in the postwar period. The novels written by Frédéric Dard from the mid-1950s to mid-1960s offer a profoundly original representation of suburban angst and what was not yet known at the time as the suburban malaise. Avoiding clichés and excessively connoted referential spaces, Dard anchor these noir novels he called “novels of the night” in landscapes that are both biographical and intertextual. The West Suburbs of Paris and what was
to become the Yvelines department are at the centre of Dard’s novelistic geography, turning into a mythical and deadly space in which is negotiated an acculturation in France of the evil and ruined world described in American noir.

Enhanced Indispensability Arguments (EIA) claim that Scientific Realists are committed to the existence of mathematical entities due to their reliance on Inference to the Best Explana- tion (IBE). Our central question concerns this purported parity of reasoning: do people who defend the EIA make an appropriate use of the resources of Scientific Realism (in particular, IBE) to achieve platonism? (§2) We argue that just because a variety of different inferential strategies can be employed by Scientific Realists does not mean that ontological conclusions concerning which things we should be Scientific Realists about are arrived at by any inferen- tial route which eschews causes (§3), and nor is there any direct pressure for Scientific Real- ists to change their inferential methods (§4). We suggest that in order to maintain inferential parity with Scientific Realism, proponents of EIA need to give details about how and in what way the presence of mathematical entities directly contribute to explanations (§5).

Rhizosphere processes play a key role in nutrient cycling in terrestrial ecosystems. Plant rhizodeposits supply low-molecular weight carbon substrates to the soil microbial community, resulting in elevated levels of activity surrounding the root. Mechanistic compartmental models that aim to model carbon flux through the rhizosphere have been reviewed and areas of future research necessary to better calibrate model parameters have been identified. Incorporating the effect of variation in bacterial biomass physiology on carbon flux presents a considerable challenge to experimentalists and modellers alike due to the difficulties associated with differentiating dead from dormant cells. A number of molecular techniques that may help to distinguish between metabolic states of bacterial cells are presented. The calibration of growth, death and maintenance parameters in rhizosphere models is also discussed. A simple model of rhizosphere carbon flow has been constructed and a sensitivity analysis was carried out on the model to highlight which parameters were most influential when simulating carbon flux. It was observed that the parameters that most heavily influenced long-term carbon compartmentalisation in the rhizosphere were exudation rate and biomass yield. It was concluded that future efforts to simulate carbon flow in the rhizosphere should aim to increase ecological realism in model structure.

This paper examines the relationship between concepts of MNE bargaining power and broader concepts of political power. It notes that the analysis of MNE bargaining power presents a number of puzzles from the perspective of political theory. These puzzles arise, in part, from the fact that the overlap between traditional concepts of MNE bargaining power and broader concepts of political power is only a partial one. Despite these problems, it is suggested that political- theory-based approaches can add realism to our understanding of bargaining power.

This paper critically analyses realist evaluation, focussing on its primary analytical concepts: mechanisms, contexts, and outcomes. Noting that nursing investigators have had difficulty in operationalizing the concepts of mechanism and context, it is argued that their confusion is at least partially the result of ambiguities, inconsistencies, and contradictions in the realist evaluation model. Problematic issues include the adoption of empiricist and idealist positions, oscillation between determinism and voluntarism, subsumption of agency under structure, and categorical confusion between context and mechanism. In relation to outcomes, it is argued that realist evaluation's adoption of the fact/value distinction prevents it from taking into account the concerns of those affected by interventions. The aim of the paper is to use these immanent critiques of realist evaluation to construct an internally consistent realist approach to evaluation that is more amenable to being operationalized by nursing researchers.

Drawing on insights from a range of disciplines, including philosophy, psychology, history, politics, but particularly sociology and sociological theory, this thesis explores the relationship between emotions and social change in late or 'liquid' modernity. It deploys the Republic of Ireland in the twentieth century as a case study. It argues that the Irish case in an ideal site for this research given the speed and scale of changes that have occurred there, particularly since the 1950's. The primary research question guiding the study is: What has been the effect of 'social change' in Ireland on the emotional lives of Irish people? The thesis is structured in three parts. Part one (chapters one to three) is primarily theoretical. It aims to develop a distinctive theoretical framework, process-relational realism, and argues that three concepts, properly treated, are central to answering the research question. These are emotion, power and (emotional) habitus. Part two is a bridging chapter, in which the empirical portion of the study, its design and method, are outlined. This study is based on a series of qualitative life-history interviews conducted using the Biographical Narrative Research Method. Part three is primarily empirical. The first chapter critically explores Bauman's concept of liquid modernity in relation to the Irish case and offers a short social history of the Irish twentieth century, which focuses on emotions and power. The second deploys two (ideal-type) interview cases to support the argument that Ireland experienced a habitus shift, from a relatively homogeneous to a heterogeneous habitus, and a corresponding shift from a relatively repressive emotional regime to a more expressive one, with significant effects on the emotional habitus. The final chapter takes a broader view of these changes, suggests that social change has been ambivalent, and outlines a new typology of emotional pathologies that the study suggests are characteristic of contemporary emotional life.

Online help-seeking is an emerging trend within the 21st century. Yet despite some movement towards developing online services, little is known about how young people locate, access and receive support online. This study aims to conceptualise the process of online help-seeking among adolescent males. Modified photo-elicitation techniques were employed within eight semi-structured focus group sessions with adolescent males aged 14 – 15 years (n= 56) across seven schools in Northern Ireland. Thematic analyses was conducted within an ontological framework of critical realism and an epistemological framework of contextualism. Informal online help-seeking pathways increased opportunity for social support and reduced stigma but also included loss of control and reduced anonymity. Formal pathways offered increased anonymity but concerns were raised regarding participants’ ability to locate and appraise the quality of information online. A conceptual model of online help-seeking has been developed to highlight the key help seeking pathways taken by adolescent males.
