    © The Author(s) 2014. This article has two aims. The first is to make the case that the ‘universe of the mind’ imagined by Yuri Lotman may be considered as a foundational model for cultural evolution (population-wide, dynamic, autopoietic, self-organising adaptation to changing environments). The second aim is to take forward a model of culture derived from Lotman’s work – a model I call ‘the clash of systems’ – in order to apply it to creative industries research. Such a move has the salutary effect of putting the ‘universe of the mind’ literally in its place. That place, now, predominantly, is in the city. Thus, the article uses Lotman’s model of the semiosphere to link different complex systems, principally the semiosphere with that of the city, in order to explore the productive potential of encounters – clashes – between different systems. Applying these insights to the field of creative industries research, the article proposes that creative culture in the globalised, urban and web-connected era can be characterised as ‘urban semiosis’

    What if communication has been pursuing the wrong kind of science? This article argues that the physics-based or ‘transmission’ model derived from Claude Shannon and criticised by James Carey does not explain how communication works. We argue instead for a model derived from the evolutionary and complexity sciences. Here, communication is based on dynamic systems of meaning (not individual ‘particles’ of information), and relations among knowledge-producing agents in culture-made groups. We call this sign-based evolutionary and systems model of communication ‘cultural science’ (Hartley and Potts, 2014), and invite communication scholars to assist in its development as a ‘modern synthesis’ for communication, along the lines of Huxley’s synthesis of botany and zoology as evolutionary bioscience

    Stories tell us? Political narrative, demes, and the transmission of knowledge through culture

    This paper compares two institutions of storytelling, mainstream national narratives and self-represented digital storytelling. It considers the centenary of World War 1, especially the Gallipoli campaign (1915) and its role in forming Australian ‘national character’. Using the new approach of cultural science, it investigates storytelling as a means by which cultures make and bind groups or ‘demes’. It finds that that demic (group-made) knowledge trumps individual experience, and that self-representation (digital storytelling) tends to copy the national narrative, even when the latter is known not to be true. The paper discusses the importance of culture in the creation of knowledge, arguing that if the radical potential of digital storytelling is to be understood – and realised – then a systems (as opposed to behavioural) approach to communication is necessary. Without a new model of knowledge, it seems we are stuck with repetition of the same old story

    Organization, Evolution, Cognition and Dynamic Capabilities

    Using insights from ‘embodied cognition’ and a resulting ‘cognitive theory of the firm’, I aim to contribute to the further development of evolutionary theory of organizations, in the specification of organizations as ‘interactors’ that carry organizational competencies as ‘replicators’, within industries as ‘populations’. Especially, I analyze how, if at all, ‘dynamic capabilities’ can be fitted into evolutionary theory. I propose that the prime purpose of an organization is to serve as a cognitive ‘focusing device’. Here, cognition has a wide meaning, including perception, interpretation, sense making, and value judgements. I analyse how this yields organizations as cohesive wholes, and differences within and between industries. I propose the following sources of variation: replication in communication, novel combinations of existing knowledge, and a path of discovery by which exploitation leads to exploration. These yield a proposal for dynamic capabilities. I discuss in what sense, and to what extent these sources of variation are ‘blind’, as postulated in evolutionary theory.

    Higher versus lower mean arterial blood pressure after cardiac arrest and resuscitation (MAP-CARE): A protocol for a randomized clinical trial.

    Get PDF
    peer reviewed[en] BACKGROUND: In patients resuscitated after cardiac arrest, a higher mean arterial pressure (MAP) may increase cerebral perfusion and attenuate hypoxic brain injury. Here we present the protocol of the mean arterial pressure after cardiac arrest and resuscitation (MAP-CARE) trial aiming to investigate the influence of MAP targets on patient outcomes. METHODS: MAP-CARE is one component of the Sedation, Temperature and Pressure after Cardiac Arrest and Resuscitation (STEPCARE) 2 x 2 x 2 factorial randomized trial. The MAP-CARE trial is an international, multicenter, parallel-group, investigator-initiated, superiority trial designed to test the hypothesis that targeting a higher (>85 mmHg) (intervention) versus a lower (>65 mmHg) (comparator) MAP after resuscitation from cardiac arrest reduces 6-month mortality (primary outcome). Trial participants are adults with sustained return of spontaneous circulation who are comatose following resuscitation from out-of-hospital cardiac arrest. The two other components of the STEPCARE trial evaluate sedation and temperature control strategies. Apart from the STEPCARE trial interventions, all other aspects of general intensive care will be according to the local practices of the participating site. Neurological prognostication will be performed according to European Resuscitation Council and European Society of Intensive Care Medicine guidelines by a physician blinded to allocation group. The sample size of 3500 participants provides 90% power with an alpha of 0.05 to detect a 5.6 absolute risk reduction in 6-month mortality, assuming a mortality of 60% in the control group. Secondary outcomes will be poor functional outcome 6 months after randomization, patient-reported overall health 6 months after randomization, and the proportion of participants with predefined severe adverse events. CONCLUSION: The MAP-CARE trial will investigate if targeting a higher MAP compared to a lower MAP during intensive care of adults who are comatose following resuscitation from out-of-hospital cardiac arrest reduces 6-month mortality

    Fever management with or without a temperature control device after out-of-hospital cardiac arrest and resuscitation (TEMP-CARE): A study protocol for a randomized clinical trial.

    peer reviewed[en] BACKGROUND: Fever is associated with brain injury after cardiac arrest. It is unknown whether fever management with a feedback-controlled device impacts patient-centered outcomes in cardiac arrest patients. This trial aims to investigate fever management with or without a temperature control device after out-of-hospital cardiac arrest. METHODS: The TEMP-CARE trial is part of the 2 × 2 × 2 factorial Sedation, TEmperature and Pressure after Cardiac Arrest and REsuscitation (STEPCARE) trial, a randomized, international, multicenter, parallel-group, investigator-initiated, superiority trial that will evaluate sedation strategies, temperature management, and blood pressure targets simultaneously in nontraumatic/nonhemorrhagic out-of-hospital cardiac arrest patients following hospital admission. For the temperature management component of the trial described in this protocol, patients will be randomly allocated to fever management with or without a feedback-controlled temperature control device. For those managed with a device, if temperature ≥37.8°C occurs within 72 h post-randomization the device will be started targeting a temperature of ≤37.5°C. Standard fever treatment, as recommended by local guidelines, including pharmacological agents, will be provided to participants in both groups. The two other components of the STEPCARE trial evaluate sedation and blood pressure strategies. Apart from the STEPCARE trial interventions, all other aspects of general intensive care will be according to the local practices of the participating site. A physician blinded to the intervention will determine the neurological prognosis following European Resuscitation Council and European Society of Intensive Care Medicine guidelines. The primary outcome is all-cause mortality at six months post-randomization. To detect a 5.6% absolute risk reduction (90% power, alpha .05), 3500 participants will be enrolled. Secondary outcomes include poor functional outcome at six months, intensive care-related serious adverse events, and overall health status at six months. CONCLUSION: The TEMP-CARE trial will investigate if post-cardiac arrest management of fever with or without a temperature control device affects patient-important outcomes after cardiac arrest

    Continuous deep sedation versus minimal sedation after cardiac arrest and resuscitation (SED-CARE): A protocol for a randomized clinical trial.

    peer reviewed[en] BACKGROUND: Sedation is often provided to resuscitated out-of-hospital cardiac arrest (OHCA) patients to tolerate post-cardiac arrest care, including temperature management. However, the evidence of benefit or harm from routinely administered deep sedation after cardiac arrest is limited. The aim of this trial is to investigate the effects of continuous deep sedation compared to minimal sedation on patient-important outcomes in resuscitated OHCA patients in a large clinical trial. METHODS: The SED-CARE trial is part of the 2 × 2 × 2 factorial Sedation, Temperature and Pressure after Cardiac Arrest and Resuscitation (STEPCARE) trial, a randomized international, multicentre, parallel-group, investigator-initiated, superiority trial with three simultaneous intervention arms. In the SED-CARE trial, adults with sustained return of spontaneous circulation (ROSC) who are comatose following resuscitation from OHCA will be randomized within 4 hours to continuous deep sedation (Richmond agitation and sedation scale (RASS) -4/-5) (intervention) or minimal sedation (RASS 0 to -2) (comparator), for 36 h after ROSC. The primary outcome will be all-cause mortality at 6 months after randomization. The two other components of the STEPCARE trial evaluate sedation and temperature control strategies. Apart from the STEPCARE trial interventions, all other aspects of general intensive care will be according to the local practices of the participating site. Neurological prognostication will be performed according to European Resuscitation Council and European Society of Intensive Care Medicine guidelines by a physician blinded to the allocation group. To detect an absolute risk reduction of 5.6% with an alpha of 0.05, 90% power, 3500 participants will be enrolled. The secondary outcomes will be the proportion of participants with poor functional outcomes 6 months after randomization, serious adverse events in the intensive care unit, and patient-reported overall health status 6 months after randomization. CONCLUSION: The SED-CARE trial will investigate if continuous deep sedation (RASS -4/-5) for 36 h confers a mortality benefit compared to minimal sedation (RASS 0 to -2) after cardiac arrest
