Social attitudes modulate automatic imitation

In naturalistic interpersonal settings, mimicry or ‘automatic imitation’ generates liking, affiliation, cooperation and other positive social attitudes. The purpose of this study was to find out whether the relationship between social attitudes and mimicry is bidirectional: Do social attitudes have a direct and specific effect on mimicry? Participants were primed with pro-social, neutral or anti-social words in a scrambled sentence task. They were then tested for mimicry using a stimulus-response compatibility procedure. In this procedure, participants were required to perform a pre-specified movement (e.g. opening their hand) on presentation of a compatible (open) or incompatible (close) hand movement. Reaction time data were collected using electromyography (EMG) and the magnitude of the mimicry / automatic imitation effect was calculated by subtracting reaction times on compatible trials from those on incompatible trials. Pro-social priming produced a larger automatic imitation effect than anti-social priming, indicating that the relationship between mimicry and social attitudes is bidirectional, and that social attitudes have a direct and specific effect on the tendency to imitate behavior without intention or conscious awareness

Recertification and Reentry to Practice for Nurse Anesthetists: Determining Core Competencies and Evaluating Performance via High-Fidelity Simulation Technology

Introduction The National Board of Certification and Recertification for Nurse Anesthetistsaddressed a barrier to return to practice of uncertified practitioners by replacing required direct patient care experiences with high-fidelity simulation. Objectives The aims of this study were to: (a) validate a set of clinical activities for their relevance to reentry and determine if they could be replicated using simulation, (b) evaluate the content validity of an existing simulation scenario containing the proposed clinical activities and determine its substitutability for a clinical practicum, and (c) evaluate the validity of two methods to assess simulation performance. Methods A modified Delphi method incorporating an autonomous, anonymous, three-round online survey process using three unique expert certified registered nurse anesthetists groups was used to address each study aim. Results Twenty-seven clinical activities gained consensus as necessary to be assessed in the simulation. All 14 survey questions used to determine simulation content validity exceeded the minimum content validity index (CVI) value of 0.78, with a mean CVI of 0.99. The global rating scale CVI and the competency checklist CVI were 0.83 and 1.0, respectively. Conclusion The findings add to the existing literature supporting the utility of simulation for high-stakes provider assessment and certification

The implications of sustainable development for airport duty-free business models

© HENRY STEWART PUBLICATIONS. This paper considers how the challenges underpinning sustainable development are likely to impact on duty-and tax-free retailing in airports and, by implication, in the entire aviation industry. The paper defines the role of retail as a vital source of airport revenues, before considering the carbon consequences of the sector’s incumbent business models. It finds that products taken onto aircraft increase aircraft weight and fuel burn and are a primary source of carbon emissions for duty-free retailers. The implications for the sector are discussed, and the potential for implementing more sustainable business models is presented. Here it is identified that the specific logistical, economic, and political constraints of operating in the airport make alternative business models difficult, if not impossible to implement. The specialisations that have helped this sector to flourish are constraining their ability to adapt to the climate challenge

A spectroscopic cell for fast pressure jumps across the glass transition line

We present a new experimental protocol for the spectroscopic study of the dynamics of glasses in the aging regime induced by sudden pressure jumps (crunches) across the glass transition line. The sample, initially in the liquid state, is suddenly brought in the glassy state, and therefore out of equilibrium, in a four-window optical crunch cell which is able to perform pressure jumps of 3 kbar in a time interval of ~10 ms. The main advantages of this setup with respect to previous pressure-jump systems is that the pressure jump is induced through a pressure transmitting fluid mechanically coupled to the sample stage through a deformable membrane, thus avoiding any flow of the sample itself in the pressure network and allowing to deal with highly viscous materials. The dynamics of the sample during the aging regime is investigated by Brillouin Light Scattering (BLS). For this purpose the crunch cell is used in conjunction with a high resolution double monochromator equipped with a CCD detector. This system is able to record a full spectrum of a typical glass forming material in a single 1 s shot. As an example we present the study of the evolution toward equilibrium of the infinite frequency longitudinal elastic modulus (M_infinity) of a low molecular weight polymer (Poly(bisphenol A-co-epichlorohydrin), glycidyl end capped). The observed time evolution of M_infinity, well represented by a single stretched exponential, is interpreted within the framework of the Tool-Narayanaswamy theory.Comment: 9 pages, 11 figure

Predictors for Readmission up to 1 Year Following Hip Fracture

Background: At Altnagelvin, a district general hospital in Northern Ireland, we have observed that a significant number of hip fracture admissions are later readmitted for treatment of other medical conditions. These readmissions place increasing stress on the already significant burden that orthopedic trauma poses on national health services. Objectives: The aim of this study was to review a series of consecutive patients managed at our unit at least 1 year prior to the onset of the study. Also, we aimed to identify predictors for raised admission rates following treatment for hip fracture. Patients and Methods: We reviewed a prospective fracture database and online patient note system for patient details, past medical history, discharge destination and routine blood tests for any factors that may influence readmission rates up to 1 year. Data were analyzed using SPSS software. Results: Over 2 years, 451 patients were reviewed and 23 were managed conservatively. There was a 1-year readmission rate of 21%. Most readmission diagnoses were medical including bronchopneumonia, falls, urosepsis, cardiac exacerbations and stroke. Prolonged length of stay and discharge to a residential, fold or nursing home were found to increase readmission rate. Readmission diagnoses closely reflected the perioperative diagnoses that prolonged length of stay. Increased odds radio and risk of readmission were also found with female gender, surgery with a cephalomedullary nail, hip hemiarthroplasty or total hip replacement, time to surgery 2 g/dL and also if a blood transfusion was received. Conclusions: Our results indicate that hip fracture treatment begins at acute fracture clerk in, with consideration of comorbid status and ultimate discharge planning remaining significant predictors for morbidity and subsequent readmission

ANIMA noise platform and ANIMA methodology : one-stop shop for aviation noise management

When you think about aviation noise, you might imagine an airplane taking off. When you think about decreasing aviation noise, the first thing that usually comes up in one’s mind are the new silent plane engines. This makes perfect sense, but it does not fully grasp the issue of aviation noise. The ANIMA project is based on a holistic approach to aviation noise, as it focuses on non-acoustical factors as well. Annoyance, as perceived by local communities surrounding airports, also depends on non-acoustical factors, which can be situational (time of the day, day of the week, activity performed while exposed to noise) and personal (sensitivity to noise, attitudes, noise insulation)

The case for a design-led, end-user focused airport noise management process.

This paper explores concept of 'design thinking' in the context of airport noise management, to inform on strategies and actions that can achieve targeted, impactful and evaluated outcomes benefitting local residents, and by extension, airports. In so doing, the we summarise the noise management challenge and the requirement for an effective ideation and implementation framework, and introduce the design thinking process as a potential means with which to do this. We suggest that design processes have the potential to play a significant role in noise management, but that significant research is required to overcome a number of barriers, to demonstrate the potential effectiveness of the approach through case study research, and for the process itself to be developed further, ideally through co-creative processes with airport noise stakeholders
