A pragmatic cluster randomised trial evaluating three implementation interventions

Background Implementation research is concerned with bridging the gap between evidence and practice through the study of methods to promote the uptake of research into routine practice. Good quality evidence has been summarised into guideline recommendations to show that peri-operative fasting times could be considerably shorter than patients currently experience. The objective of this trial was to evaluate the effectiveness of three strategies for the implementation of recommendations about peri-operative fasting. Methods A pragmatic cluster randomised trial underpinned by the PARIHS framework was conducted during 2006 to 2009 with a national sample of UK hospitals using time series with mixed methods process evaluation and cost analysis. Hospitals were randomised to one of three interventions: standard dissemination (SD) of a guideline package, SD plus a web-based resource championed by an opinion leader, and SD plus plan-do-study-act (PDSA). The primary outcome was duration of fluid fast prior to induction of anaesthesia. Secondary outcomes included duration of food fast, patients' experiences, and stakeholders' experiences of implementation, including influences. ANOVA was used to test differences over time and interventions. Results Nineteen acute NHS hospitals participated. Across timepoints, 3,505 duration of fasting observations were recorded. No significant effect of the interventions was observed for either fluid or food fasting times. The effect size was 0.33 for the web-based intervention compared to SD alone for the change in fluid fasting and was 0.12 for PDSA compared to SD alone. The process evaluation showed different types of impact, including changes to practices, policies, and attitudes. A rich picture of the implementation challenges emerged, including inter-professional tensions and a lack of clarity for decision-making authority and responsibility. Conclusions This was a large, complex study and one of the first national randomised controlled trials conducted within acute care in implementation research. The evidence base for fasting practice was accepted by those participating in this study and the messages from it simple; however, implementation and practical challenges influenced the interventions' impact. A set of conditions for implementation emerges from the findings of this study, which are presented as theoretically transferable propositions that have international relevance.

Quantum Non-Objectivity from Performativity of Quantum Phenomena

We analyze the logical foundations of quantum mechanics (QM) by stressing non-objectivity of quantum observables which is a consequence of the absence of logical atoms in QM. We argue that the matter of quantum non-objectivity is that, on the one hand, the formalism of QM constructed as a mathematical theory is self-consistent, but, on the other hand, quantum phenomena as results of experimenter's performances are not self-consistent. This self-inconsistency is an effect of that the language of QM differs much from the language of human performances. The first is the language of a mathematical theory which uses some Aristotelian and Russellian assumptions (e.g., the assumption that there are logical atoms). The second language consists of performative propositions which are self-inconsistent only from the viewpoint of conventional mathematical theory, but they satisfy another logic which is non-Aristotelian. Hence, the representation of quantum reality in linguistic terms may be different: from a mathematical theory to a logic of performative propositions. To solve quantum self-inconsistency, we apply the formalism of non-classical self-referent logics

The brain is a prediction machine that cares about good and bad - Any implications for neuropragmatics?

Experimental pragmatics asks how people construct contextualized meaning in communication. So what does it mean for this field to add neuroas a prefix to its name? After analyzing the options for any subfield of cognitive science, I argue that neuropragmatics can and occasionally should go beyond the instrumental use of EEG or fMRI and beyond mapping classic theoretical distinctions onto Brodmann areas. In particular, if experimental pragmatics ‘goes neuro’, it should take into account that the brain evolved as a control system that helps its bearer negotiate a highly complex, rapidly changing and often not so friendly environment. In this context, the ability to predict current unknowns, and to rapidly tell good from bad, are essential ingredients of processing. Using insights from non-linguistic areas of cognitive neuroscience as well as from EEG research on utterance comprehension, I argue that for a balanced development of experimental pragmatics, these two characteristics of the brain cannot be ignored

Developing the adjudicated case study method

In this commentary we discuss Miller’s Panel of Psychological Inquiry (PPI) and Bohart’s Research Jury method approaches to the development of the adjudicated case study method, as represented by the papers assembled for this issue of Pragmatic Case Studies in Psychotherapy. In our view, the case studies presented here demonstrate the rapidly developing potential offered by this approach for psychotherapy research and reveal many parallels to recent research using the Hermeneutic Single Case Efficacy Design (HSCED) model. In our view, each of the three models has taken significant steps forward in adapting particular aspects of the legal process as viable psychotherapy research procedures. In this commentary we summarize the HSCED method, then take readers through the issues of the sources of the evidence used; ways in which that evidence is tested; claims, burden and standard of proof; and the handling of the adjudication process itself. We conclude with recommendations for further development of adjudicated case study methods

The Frankfurt School and the young Habermas: Traces of an intellectual path (1956–1964)

The aim of this study is to discern intersections between the intellectual path of the young Habermas and the issues addressed by the Positivismusstreit, the dispute between Popper and Adorno about methodology in the social sciences. I will present two perspectives, focusing on different temporal moments and interpretative problems. First, I will investigate the young Habermas’ relationship to the intellectual tradition of the Frankfurt School: his views on philosophy and the social sciences, normative bases of critical theory and political attitudes. Second, I will reconstruct Habermas’ contemplation of the Positivismusstreit, in light of his social scientific research programme in the 1960s. The thesis supported is that Habermas developed a position diverging from those of Adorno and Horkheimer, and that his position reasserted the agenda of the ‘first critical theory’. This article highlight the discontinuity between the first and the second generation of the Frankfurt School, the constructive openness to other philosophical and sociological traditions, as well as the aporias of a theory of knowledge not yet oriented towards the programme of reconstructive sciences

HR Contribution to IT Innovation Implementation: Results of Three Case Studies

The theoretical and empirical investigation of information technologies (IT) innovation implementations reveals that they lack conceptual and practical support from HRM professionals. The HRM practices undertaken by HR professionals are not even discussed. We argue that HR departments should contribute to IT innovation projects by being responsible for explicitly defining job tasks that have to be automated, establishing a rewards system for those who have to learn and use a new technology and analysing the training needs of the users and providing them with adequate training. HRM should more actively intervene in IT innovation projects. Such intervention would, we believe, foster compatibility between the prior intentions of information technology, the strategies and practices, the individual users’ needs in it and the adoption of IT by the users

Topic Independent Identification of Agreement and Disagreement in Social Media Dialogue

Research on the structure of dialogue has been hampered for years because large dialogue corpora have not been available. This has impacted the dialogue research community's ability to develop better theories, as well as good off the shelf tools for dialogue processing. Happily, an increasing amount of information and opinion exchange occur in natural dialogue in online forums, where people share their opinions about a vast range of topics. In particular we are interested in rejection in dialogue, also called disagreement and denial, where the size of available dialogue corpora, for the first time, offers an opportunity to empirically test theoretical accounts of the expression and inference of rejection in dialogue. In this paper, we test whether topic-independent features motivated by theoretical predictions can be used to recognize rejection in online forums in a topic independent way. Our results show that our theoretically motivated features achieve 66% accuracy, an improvement over a unigram baseline of an absolute 6%.Comment: @inproceedings{Misra2013TopicII, title={Topic Independent Identification of Agreement and Disagreement in Social Media Dialogue}, author={Amita Misra and Marilyn A.

Mann der Tat, Enterprise Culture und Ethno-preneurs: Eine Diskussion kritischer, affirmativer und pragmatischer Entrepreneurship- Ansätze am Beispiel Spaniens

This contribution suggests a classification of different anthropological contributions to entrepreneurship research. Critical approaches to entrepreneurship focus on the ideological bias of the term. As the work of Mary Douglas, they critique the methodological individualism and the utilitarian self-concept underlying the entrepreneur. Affirmative approaches, in the tradition of Joseph Schumpeter or Frederik Barth, are concerned with the definition, understanding and transformative outcomes of entrepreneurship. Pragmatic approaches use tactically the social eminence of the term by expanding it to a wide range of apparently distant topics, such as the ‘ethno-preneur’ coined by John and Jean Comaroff. To illustrate the analytical scope of each of these approaches, I discuss some of my empirical material from Spain, such as the discourse on entrepreneurship in the 2015 parliamentary elections, the case of a media entrepreneur in rural Andalusia and the politics of heritage entrepreneurship and the Mediterranean diet in Catalonia
