    Introduction Stressful situations pervade emergency medicine. Many studies demonstrate the deleterious impacts of stress on a physician’s immediate actions and lasting mental health. It is well-documented in the literature that preparedness can help mediate stress. Stress inoculation training (SIT) is utilized to prevent adverse stress response. This training teaches coping skills and defensive thinking to actively mitigate the negative physiological effects that occur during stressful events. SIT theory involves a conceptualization phase, skills training phase and application phase. The goal of this study is to evaluate the effect of SIT on endotracheal intubation performance of novice intubators. Methods The study consists of a population of medical students without prior airway training who are randomly assigned to control and intervention groups. Both groups will receive a didactic lecture on airway management followed by a brief intubation attempt on a standard dummy. The experimental group will subsequently receive a lecture on the principles of SIT where they learn to use focused intervention shown to reduce the physiological effects of stress. These techniques include box breathing, positive self-talk and imagery. All participants will then intubate the standard dummy in three different scenarios of varying environmental stressors. The main outcome will be the participant’s ability to successfully perform the procedure. Secondary outcomes will be the number of attempts and time required to successfully intubate, as well as, the participant\u27s post event response to the Perceived Stress Questionnaire. To evaluate the lasting effects of SIT, both groups will return in a month and repeat the intubation scenarios. Results Due to COVID-19 restrictions, pilot testing has been postponed until Fall 2020. Data analysis will focus on participant’s ability to perform the procedure under stressful conditions, their perception of stress, time to intubation and number of attempts. Conclusion The study evaluates the teaching of stress inoculation training (SIT) on emergency airway management. We hope this application of SIT will not only contribute to a growing body of literature on stress management, but also enhance patient safety and better prepare medical students for career resiliency

    Evidence for Localized High Temperature Hydrothermal Fluid Flow within the Sub-Crater Environment of the Rochechouart Impact Structure: Observations from a Polymict Breccia Dike

    Hypervelocity impacts into volatilebearing terrestrial targets can initiate hydrothermal circulation for a finite period of time; evidence for this is preserved in approximately one-third of impact structures on Earth [1, 2]. Hydrothermal environments can host extremophile life, and microbial communities have been found to colonize impact craters [3, 4]. The majority of impact structures on Earth have yet to be studied in great detail; many aspects of the post-impact environment such as the extent and duration hydrothermal circulation with respect to location within the structure as well as crater diameter, target composition and external influences, (paleogeography) are not fully understood. <p></p>We present evidence for high temperature hydrothermal fluid circulation within the sub-crater environment of the highly eroded, 23km diameter, Mesozoic Rochechouart impact structure located in west-central France [5]. This evidence is a new impact lithology that was found during a recent field campaign at a collection site located approximately 7.5km north-east of the structure's center. It is a highly porous, polymict lithic impact breccia dike containing carbonate mineralization found below the transient crater floor. Secondary hydrothermal mineral assemblages are diagnostic of a range of temperatures (>100°C to low temperature diagenetic).<p></p&gt

    Scottish social survey data, past present and future:Does Scotland need its own data strategy?

    Get PDF
    The UK now has a National Data Strategy. In this paper we explore whether or not in addition Scotland needs its own specific data strategy. This paper is intended to be a ‘think piece’ or critical essay, the motivation being to encourage debate about Scottish social survey data. Post-devolution, with the emergence of new forms of governance and new institutional arrangements, the political desire to research Scotland in the 21st Century has been brought into sharper resolution. Social and economic life in Scotland shares both similarities and differences with life south of the border. It is important that these characteristics are correctly identified with empirical data rather than simply being assumed. Scotland is a small territory with a good social science tradition and a healthy research sector. There is an increasing amount of survey data collecting measures relating to social and economic life in Scotland. These include both United Kingdom or Great Britain based surveys with a Scottish component, and Scotland focussed surveys. In this paper we outline a number of key issues relating to Scottish social science data resources. We provide a number of critical recommendations for social science data collection in Scotland. Finally, we examine the potential benefits of a comprehensive data strategy

    M-Theory and Hypercharge

    We discuss the possibility that the electro-weak and strong interactions arise as the low energy effective description of branes in M-theory. As a step towards constructing such a model we show how one can naturally obtain SU(N_1)\times SU(N_2)\times U(1) gauge theories from branes, including matter in the bi-fundamental representation of SU(N_1)\times SU(N_2) which are fractionally charged under U(1).Comment: 29 pages Phyzzx.

    N=2 Superfields and the M-Fivebrane

    Full text link
    In this paper we provide a manifestly N=2 supersymmetric formulation of the M-fivebrane in the presence of threebrane solitons. The superspace form of four-dimensional effective equations for the threebranes are readily obtained and yield the complete Seiberg-Witten equations of motion for N=2 super-Yang-Mills. A particularly simple derivation is given by introducing an N=2 superfield generalisation of the Seiberg-Witten differential.Comment: 14 pages phyzzx. Added paragraph on the existence of a six-dimensional action. To appear in Phys. Lett.

    We discuss the supersymmetry algebra of the M theory fivebrane and obtain a new threebrane soliton preserving half of the six-dimensional supersymmetry. This solution is dimensionally reduced to various D-p-branes.Comment: 10 pages, phyzz

    A New Massive Type IIA Supergravity From Compactification

    Full text link
    We consider the most general form for eleven dimensional supersymmetry compatible with on-shell superfields. This allows for the introduction of a conformal Spin(1,10) connection. In eleven dimensional Minkowski space this modification is trivial and can be removed by a field redefinition, however, upon compactification on S^1 it is possible to introduce a non-trivial `Wilson line'. The resulting ten dimensional supergravity has massive 1-form and 3-form potentials and a cosmological constant. This theory does not possess a supersymmetric eightbrane soliton but it does admit a supersymmetric non-static cosmological solution.Comment: 13 pages, phyzzx. The introduction is clarifed and a reference adde

    Partial inner product spaces: Some categorical aspects

    We make explicit in terms of categories a number of statements from the theory of partial inner product spaces (PIP spaces) and operators on them. In particular, we construct sheaves and cosheaves of operators on certain PIP spaces of practical interest.Comment: 21 page
