    The selection of appropriate frames of reference (FOR) is a key factor in the elaboration of spatial perception and the production of robust interaction with our environment. The extent to which we perceive the head axis orientation (subjective head orientation, SHO) with both accuracy and precision likely contributes to the efficiency of these spatial interactions. A first goal of this study was to investigate the relative contribution of both the visual and egocentric FOR (centre-of-mass) in the SHO processing. A second goal was to investigate humans' ability to process SHO in various sensory response modalities (visual, haptic and visuo-haptic), and the way they modify the reliance to either the visual or egocentric FORs. A third goal was to question whether subjects combined visual and haptic cues optimally to increase SHO certainty and to decrease the FORs disruption effect.Thirteen subjects were asked to indicate their SHO while the visual and/or egocentric FORs were deviated. Four results emerged from our study. First, visual rod settings to SHO were altered by the tilted visual frame but not by the egocentric FOR alteration, whereas no haptic settings alteration was observed whether due to the egocentric FOR alteration or the tilted visual frame. These results are modulated by individual analysis. Second, visual and egocentric FOR dependency appear to be negatively correlated. Third, the response modality enrichment appears to improve SHO. Fourth, several combination rules of the visuo-haptic cues such as the Maximum Likelihood Estimation (MLE), Winner-Take-All (WTA) or Unweighted Mean (UWM) rule seem to account for SHO improvements. However, the UWM rule seems to best account for the improvement of visuo-haptic estimates, especially in situations with high FOR incongruence. Finally, the data also indicated that FOR reliance resulted from the application of UWM rule. This was observed more particularly, in the visual dependent subject. Conclusions: Taken together, these findings emphasize the importance of identifying individual spatial FOR preferences to assess the efficiency of our interaction with the environment whilst performing spatial tasks

    Going against the herd: psychological and cultural factors underlying the 'vaccination confidence gap'

    By far the most common strategy used in the attempt to modify negative attitudes toward vaccination is to appeal to evidence-based reasoning. We argue, however, that focusing on science comprehension is inconsistent with one of the key facts of cognitive psychology: Humans are biased information processors and often engage in motivated reasoning. On this basis, we hypothesised that negative attitudes can be explained primarily by factors unrelated to the empirical evidence for vaccination; including some shared attitudes that also attract people to complementary and alternative medicine (CAM). In particular, we tested psychosocial factors associated with CAM endorsement in past research; including aspects of spirituality, intuitive (vs analytic) thinking styles, and the personality trait of openness to experience. These relationships were tested in a cross-sectional, stratified CATI survey (N = 1256, 624 Females). Whilst educational level and thinking style did not predict vaccination rejection, psychosocial factors including: preferring CAM to conventional medicine (OR .49, 95% CI .36 .83, 95% CI .71 to vaccination. Furthermore, for 9 of the 12 CAMs surveyed, utilisation in the last 12 months was associated with lower levels of vaccination endorsement. From this we suggest that vaccination scepticism appears to be the outcome of a particular cultural and psychological orientation leading to unwillingness to engage with the scientific evidence. Vaccination compliance might be increased either by building general confidence and understanding of evidence-based medicine, or by appealing to features usually associated with CAM, e.g.–.66), endorsement of spirituality as a source of knowledge (OR–.96), and openness (OR .86, 95% CI .74–.99), all predicted negative attitudes‘strengthening your natural resistance to disease’

    How parents choose to use CAM: a systematic review of theoretical models

    Background: Complementary and Alternative Medicine (CAM) is widely used throughout the UK and the Western world. CAM is commonly used for children and the decision-making process to use CAM is affected by numerous factors. Most research on CAM use lacks a theoretical framework and is largely based on bivariate statistics. The aim of this review was to identify a conceptual model which could be used to explain the decision-making process in parental choice of CAM. Methods: A systematic search of the literature was carried out. A two-stage selection process with predetermined inclusion/exclusion criteria identified studies using a theoretical framework depicting the interaction of psychological factors involved in the CAM decision process. Papers were critically appraised and findings summarised. Results: Twenty two studies using a theoretical model to predict CAM use were included in the final review; only one examined child use. Seven different models were identified. The most commonly used and successful model was Andersen's Sociobehavioural Model (SBM). Two papers proposed modifications to the SBM for CAM use. Six qualitative studies developed their own model. Conclusion: The SBM modified for CAM use, which incorporates both psychological and pragmatic determinants, was identified as the best conceptual model of CAM use. This model provides a valuable framework for future research, and could be used to explain child CAM use. An understanding of the decision making process is crucial in promoting shared decision making between healthcare practitioners and parents and could inform service delivery, guidance and policy

    Measuring Quality of Care in Patients With Nonvariceal Upper Gastrointestinal Hemorrhage: Development of an Explicit Quality Indicator Set

    No full text
    OBJECTIVES: With an increasing emphasis on quality in health care and recognition of inconsistencies in the management of patients with nonvariceal upper gastrointestinal hemorrhage (NVUGIH), it is critical to establish a set of explicit quality indicators (QIs) in NVUGIH. METHODS: We conducted a nine-member, multidisciplinary expert panel and followed modified Delphi methods to systematically identify a set of QIs for NVUGIH. The panel performed independent ratings of each candidate QI using a nine-point RAND appropriateness scale, then met in person and re-voted using an iterative process of discussion. The final set comprised QIs with a median RAND Appropriateness Score >= 7 and no disagreement among experts. RESULTS: Among 116 candidate QIs, the panel rated 26 as valid measures of quality care. The selected QIs cover pre-endoscopy, endoscopy, and post-endoscopy care, including diagnosis, early resuscitation, risk stratification, endoscopic care, Helicobacter pylori management, and proton pump inhibitor therapy. CONCLUSIONS: We have developed an explicit set of evidence-based QIs in NVUGIH, providing physicians and institutions with a tool to identify processes amenable to quality improvement. This tool is intended to be applicable in all institutions providing care for NVUGIH patients

    Clinical/translational research can be separated into two components, T1 and T2. T1 research applies discoveries generated during preclinical laboratory research to the development of clinical efficacy trials in humans, leading up to the submission of a New Drug Application or an amended New Drug Application claiming new uses of an approved medication. The second component of translation research, T2, is aimed at developing and identifying actions, interventions, or practices that enhance the effectiveness of approved agents in the larger population. The delivery of effective treatments through the implementation and evaluation of best practice guidelines within practice settings is another component of T2 research, but some authors have broken this aspect of patient care and practice into a subcategory of T2 research or simply labeled it as T3 research.1,2 Clinical and/or translational research are not new areas of research, but their importance in improving the public's health was heightened with the introduction of the National Institutes of Health (NIH) Roadmap programs and by the Roadmap's Clinical and Translational Science Award (CTSA) program which aims to consolidate a number of NIH clinical research and training programs at the nation's Academic Health Centers (AHCs).3,4 A primary requirement for a successful CTSA program is the demonstration of involvement of several health professions colleges/schools that are either members of the submitting institution's AHCs or from a medical school and health professions programs at another institution. A number of the successful CTSA applications have significant involvement of colleges/schools of pharmacy
