    Intermedia Remediated & the Question of Designing Discourse

    Get PDF
    New “engines of discourse” (neural networks, algorithms and other forms of artificial intelligence, combined with the devices that record and interpret viewer actions) bring to the fore rhetorical concerns that challenge discipline-based notions of process and form. We shall focus here on the tradition of intermedial art practices to better understand the ever more complex question of how to inter-relate three aspects of digital communication: authorial “intent”, the digital sign and its interactive exploration by a “spect-actor”. We shall argue that the digital sign is an extension of intermedial thinking rooted in a pre-digital, photographic practice and esthetic. The writings of several French theorists on the subject of interactive digital design will provide a context for understanding examples of “virtual art-realities”, whose specificity is staging relationships between objects and people. Keywords: Rhetoric; Discourse; Intermedia; Interactivity; Digital Sign; Esthetics; Artificial Intelligence; Behavior-based Art.</p

    Background Emergency ambulance services are integral to providing a service for those with unplanned urgent and life-threatening health conditions. However, high use of the service by a small minority of patients is a concern. Our objectives were to describe: service-wide and local policies or pathways for people classified as Frequent Caller; call volume; and results of any audit or evaluation. Method We conducted a national survey of current practice in ambulance services in relation to the management of people who call the emergency ambulance service frequently using a structured questionnaire for completion by email and telephone interview. We analysed responses using a descriptive and thematic approach. Results Twelve of 13 UK ambulance services responded. Most services used nationally agreed definitions for ‘Frequent Caller’, with 600–900 people meeting this classification each month. Service-wide policies were in place, with local variations. Models of care varied from within-service care where calls are flagged in the call centre; contact made with callers; and their General Practitioner (GP) with an aim of discouraging further calls, to case management through cross-service, multi-disciplinary team meetings aiming to resolve callers’ needs. Although data were available related to volume of calls and number of callers meeting the threshold for definition as Frequent Caller, no formal audits or evaluations were reported. Conclusions Ambulance services are under pressure to meet challenging response times for high acuity patients. Tensions are apparent in the provision of care to patients who have complex needs and call frequently. Multi-disciplinary case management approaches may help to provide appropriate care, and reduce demand on emergency services. However, there is currently inadequate evidence to inform commissioning, policy or practice development

    Towards integrating evolution, metabolism, and climate change studies of marine ecosystems

    Marine ecosystems are changing and the services they provide are threatened by global environmental changes. Environmental changes can provoke evolution of species, affecting both the realized and fundamental niches of species. Environmental change can drive evolution, but evolution can also affect environmental conditions. There is a need for a unifying framework that combines studies of evolution, metabolism, and climate change. That framework should be based on ecological theory, on the study of the realized and fundamental niche dynamics, their spatial and temporal dynamics, and their potential response to environmental changes

    BHPR research: qualitative1. Complex reasoning determines patients' perception of outcome following foot surgery in rheumatoid arhtritis

    Background: Foot surgery is common in patients with RA but research into surgical outcomes is limited and conceptually flawed as current outcome measures lack face validity: to date no one has asked patients what is important to them. This study aimed to determine which factors are important to patients when evaluating the success of foot surgery in RA Methods: Semi structured interviews of RA patients who had undergone foot surgery were conducted and transcribed verbatim. Thematic analysis of interviews was conducted to explore issues that were important to patients. Results: 11 RA patients (9 ♂, mean age 59, dis dur = 22yrs, mean of 3 yrs post op) with mixed experiences of foot surgery were interviewed. Patients interpreted outcome in respect to a multitude of factors, frequently positive change in one aspect contrasted with negative opinions about another. Overall, four major themes emerged. Function: Functional ability & participation in valued activities were very important to patients. Walking ability was a key concern but patients interpreted levels of activity in light of other aspects of their disease, reflecting on change in functional ability more than overall level. Positive feelings of improved mobility were often moderated by negative self perception ("I mean, I still walk like a waddling duck”). Appearance: Appearance was important to almost all patients but perhaps the most complex theme of all. Physical appearance, foot shape, and footwear were closely interlinked, yet patients saw these as distinct separate concepts. Patients need to legitimize these feelings was clear and they frequently entered into a defensive repertoire ("it's not cosmetic surgery; it's something that's more important than that, you know?”). Clinician opinion: Surgeons' post operative evaluation of the procedure was very influential. The impact of this appraisal continued to affect patients' lasting impression irrespective of how the outcome compared to their initial goals ("when he'd done it ... he said that hasn't worked as good as he'd wanted to ... but the pain has gone”). Pain: Whilst pain was important to almost all patients, it appeared to be less important than the other themes. Pain was predominately raised when it influenced other themes, such as function; many still felt the need to legitimize their foot pain in order for health professionals to take it seriously ("in the end I went to my GP because it had happened a few times and I went to an orthopaedic surgeon who was quite dismissive of it, it was like what are you complaining about”). Conclusions: Patients interpret the outcome of foot surgery using a multitude of interrelated factors, particularly functional ability, appearance and surgeons' appraisal of the procedure. While pain was often noted, this appeared less important than other factors in the overall outcome of the surgery. Future research into foot surgery should incorporate the complexity of how patients determine their outcome Disclosure statement: All authors have declared no conflicts of interes

    Objectives To determine whether progressive skin fibrosis is associated with visceral organ progression and mortality during follow-up in patients with diffuse cutaneous systemic sclerosis (dcSSc). Methods We evaluated patients from the European Scleroderma Trials and Research database with dcSSc, baseline modified Rodnan skin score (mRSS) ≄7, valid mRSS at 12±3 months after baseline and ≄1 annual follow-up visit. Progressive skin fibrosis was defined as an increase in mRSS &gt;5 and ≄25% from baseline to 12±3 months. Outcomes were pulmonary, cardiovascular and renal progression, and all-cause death. Associations between skin progression and outcomes were evaluated by Kaplan-Meier survival analysis and multivariable Cox regression. Results Of 1021 included patients, 78 (7.6%) had progressive skin fibrosis (skin progressors). Median follow-up was 3.4 years. Survival analyses indicated that skin progressors had a significantly higher probability of FVC decline ≄10% (53.6% vs 34.4%; p&lt;0.001) and all-cause death (15.4% vs 7.3%; p=0.003) than non-progressors. These significant associations were also found in subgroup analyses of patients with either low baseline mRSS (≀22/51) or short disease duration (≀15 months). In multivariable analyses, skin progression within 1 year was independently associated with FVC decline ≄10% (HR 1.79, 95% CI 1.20 to 2.65) and all-cause death (HR 2.58, 95% CI 1.31 to 5.09). Conclusions Progressive skin fibrosis within 1 year is associated with decline in lung function and worse survival in dcSSc during follow-up. These results confirm mRSS as a surrogate marker in dcSSc, which will be helpful for cohort enrichment in future trials and risk stratification in clinical practice

    Schizophrenia has a heritability of 60-80%1, much of which is attributable to common risk alleles. Here, in a two-stage genome-wide association study of up to 76,755 individuals with schizophrenia and 243,649 control individuals, we report common variant associations at 287 distinct genomic loci. Associations were concentrated in genes that are expressed in excitatory and inhibitory neurons of the central nervous system, but not in other tissues or cell types. Using fine-mapping and functional genomic data, we identify 120 genes (106 protein-coding) that are likely to underpin associations at some of these loci, including 16 genes with credible causal non-synonymous or untranslated region variation. We also implicate fundamental processes related to neuronal function, including synaptic organization, differentiation and transmission. Fine-mapped candidates were enriched for genes associated with rare disruptive coding variants in people with schizophrenia, including the glutamate receptor subunit GRIN2A and transcription factor SP4, and were also enriched for genes implicated by such variants in neurodevelopmental disorders. We identify biological processes relevant to schizophrenia pathophysiology; show convergence of common and rare variant associations in schizophrenia and neurodevelopmental disorders; and provide a resource of prioritized genes and variants to advance mechanistic studies

    Today's net-art draws much of its inspiration from conceptual art and the formal experiments with time led by the art movement Fluxus. Founded by George Maciunas, Dick Higgins and George Brecht in the sixties, Fluxus questions the procedural and conceptual premises underlying formal categories such as medium, genre and media. In so doing it breaks down the roles traditionally attributed to author, object and spectator in the production and the reception of works of art. We explore these collaborative and process-oriented art practices and their impact on net-art, with particular emphasis on the term "intermedia", often used by contemporary digital artists. Our approach is comparative, based on a detailed analysis of individual web-sites. We seek to reveal the specific attributes of emerging art forms on internet, within the broader context of an art historical tradition.Les artistes en rĂ©seau s'inscrivent dans une tradition Ă  la fois conceptuelle et participative qui trouve ses sources en particulier dans les expĂ©riences fluxiennes sur le temps. Le mouvement international Fluxus, dont les pĂšres fondateurs sont Maciunas, Brecht et Higgins, rĂ©unit dans les annĂ©es 60 des artistes qui explorent l'hybridation des mĂ©dias et jouent de la prĂ©caritĂ© de l'intention artistique dans les diffĂ©rentes incarnations qu'elle suscite. Les dimensions intermedia et collaboratives de ces pratiques trouvent aujourd'hui un terrain particuliĂšrement fertile sur Internet. Pour comprendre cette filiation au delĂ  d'un certain Ă©tat d'esprit, il faut reprendre les donnĂ©es du systĂšme fluxien et les confronter aux rĂ©alisations de l'art en rĂ©seau. Ce travail permet de dĂ©finir les spĂ©cificitĂ©s de l'art sur internet en dĂ©gageant les principes formels qui le rattache Ă  certains pans de l'histoire de l'art mais aussi en repĂ©rant son originalitĂ© propre.Holzberger-Braun Carol-Ann, GentĂšs Annie.
