Designing studies with an internal pilot phase may optimise the use of pilot work to inform more efficient randomised controlled trials (RCTs). Careful selection of preagreed decision or 'progression' criteria at the juncture between the internal pilot and main trial phases provides a valuable opportunity to evaluate the likely success of the main trial and optimise its design or, if necessary, to make the decision not to proceed with the main trial. Guidance on the appropriate selection and application of progression criteria is, however, lacking. This paper outlines the key issues to consider in the optimal development and review of operational progression criteria for RCTs with an internal pilot phase. A structured literature review and exploration of stakeholders' opinions at a Medical Research Council (MRC) Hubs for Trials Methodology Research workshop. Key stakeholders included triallists, methodologists, statisticians and funders. There is considerable variation in the use of progression criteria for RCTs with an internal pilot phase, although 3 common issues predominate: trial recruitment, protocol adherence and outcome data. Detailed and systematic reporting around the decision-making process for stopping, amending or proceeding to a main trial is uncommon, which may hamper understanding in the research community about the appropriate and optimal use of RCTs with an internal pilot phase. 10 top tips for the development, use and reporting of progression criteria for internal pilot studies are presented. Systematic and transparent reporting of the design, results and evaluation of internal pilot trials in the literature should be encouraged in order to facilitate understanding in the research community and to inform future trials.

Horner, Janice K; Piercy, Brigit S; Eure, Lois; Woodard, Elizabeth K

2014-08-01

The purpose of the Mindful Nursing Pilot Study was to explore the impact of mindfulness training for nursing staff on levels of mindfulness, compassion satisfaction, burnout, and stress. In addition, the study attempted to determine the impact on patient satisfaction scores. The pilot was designed as a quasi-experimental research study; staff on one nursing unit participated in the 10-week mindfulness training program while another, similar nursing unit served as the control group. The intervention group showed improvement in levels of mindfulness, burnout, and stress as well as patient satisfaction while the control group remained largely the same. This pilot provides encouraging results that suggest that replication and further study of mindfulness in the workplace would be beneficial. Copyright © 2014 Elsevier Inc. All rights reserved.

The challenge of regional accents for aviation English language proficiency standards: a study of difficulties in understanding in air traffic control-pilot communications.

PubMed

Tiewtrakul, T; Fletcher, S R

2010-02-01

Although English has been the international aviation language since 1951, formal language proficiency testing for key aviation personnel has only recently been implemented by the International Civil Aviation Organization (ICAO). It aims to ensure minimum acceptable levels of English pronunciation and comprehension universally, but does not attend to particular regional dialect difficulties. However, evidence suggests that voice transmissions between air traffic controllers and pilots are a particular problem in international airspace and that pilots may not understand messages due to the influence of different accents when using English. This study explores the potential impact of 'non-native English' in pilot-air traffic control transmissions using a 'conversation analysis' technique to examine approach phase recordings from Bangkok International Airport. Results support that communication errors, defined by incidents of pilots not understanding, occur significantly more often when speakers are both non-native English, messages are more complex and when numerical information is involved. These results and their possible implications are discussed with reference to the development of ICAO's new language proficiency standards. Statement of Relevance: This study builds on previous work and literature, providing further evidence to show that the risks caused by language and linguistics in aviation must be explored more deeply. Findings are particularly contemporary and relevant today, indicating that recently implemented international standards would benefit from further exploratory research and development.

Methodological challenges in evaluating the effectiveness of women's crisis houses compared with psychiatric wards: findings from a pilot patient preference RCT.

PubMed

2009-10-01

There are several methodological difficulties to address when evaluating acute psychiatric services. This study explored potential methods in evaluating the effectiveness of women's crisis houses compared with psychiatric wards in a pilot patient preference randomized controlled trial. Women requiring voluntary admission to a psychiatric hospital or women's crisis house were asked to enter this pilot and different options for recruitment were explored, including different recruitment sites in the pathway to admission and methods for including women without capacity. Forty-one percent (n = 42) of women entering the study agreed to be randomized and 59% (n = 61) entered patient preference arms. Only 7% of women were recruited before admission and 1 woman without capacity entered the study, despite procedures to facilitate this. Recruitment of patients with acute psychiatric crises is therefore challenging; researchers evaluating acute services should establish a consensus on how ethically and practically to recruit patients in this setting.

The piloting of fighting aircraft, the navigation of space-shuttle, the piloting of an helicopter in tactical flight at an altitude of 50 metres require the use of all sensorial, ocular, vestibular, proprioceptive ... sensors. So, the selection and the follow-up of these aerial engines' pilots need a very complete study of medical parameters, in particular sensorial and notably visual system. The doctors and the expert researchers in Aeronautical and spatial Medicine of the Army Health Department, which have in charge the medical supervision of flight crew, should study, create, and improve tests of visual sensorial exploration developed from fundamental and applied research. These authenticated tests with military pilots were applied in ophthalmology for the estimation of normal and deficient vision. A proposition to change norms of World Health Organisation applied to the vision has been following these to low visual persons was equally introduced.

Scaling Down to Scale Up: A Health Economic Analysis of Integrating Point-of-Care Syphilis Testing into Antenatal Care in Zambia during Pilot and National Rollout Implementation

Maternal syphilis results in an estimated 500,000 stillbirths and neonatal deaths annually in Sub-Saharan Africa. Despite the existence of national guidelines for antenatal syphilis screening, syphilis testing is often limited by inadequate laboratory and staff services. Recent availability of inexpensive rapid point-of-care syphilis tests (RST) can improve access to antenatal syphilis screening. A 2010 pilot in Zambia explored the feasibility of integrating RST within prevention of mother-to-child-transmission of HIV services. Following successful demonstration, the Zambian Ministry of Health adopted RSTs into national policy in 2011. Cost data from the pilot and 2012 preliminary national rollout were extracted from project records, antenatal registers, clinic staff interviews, and facility observations, with the aim of assessing the cost and quality implications of scaling up a successful pilot into a national rollout. Start-up, capital, and recurrent cost inputs were collected, including costs of extensive supervision and quality monitoring during the pilot. Costs were analysed from a provider’s perspective, incremental to existing antenatal services. Total and unit costs were calculated and a multivariate sensitivity analysis was performed. Our accompanying qualitative study by Ansbro et al. (2015) elucidated quality assurance and supervisory system challenges experienced during rollout, which helped explain key cost drivers. The average unit cost per woman screened during rollout ($11.16) was more than triple the pilot unit cost ($3.19). While quality assurance costs were much lower during rollout, the increased unit costs can be attributed to several factors, including higher RST prices and lower RST coverage during rollout, which reduced economies of scale. Pilot and rollout cost drivers differed due to implementation decisions related to training, supervision, and quality assurance. This study explored the cost of integrating RST into antenatal care in pilot and national rollout settings, and highlighted important differences in costs that may be observed when moving from pilot to scale-up.

Little is known regarding the symptoms of fatigue that maritime pilots experience during shift work. Moreover, the strategies these individuals use to cope with the onset of fatigue are also unknown. The current study explored the symptoms of fatigue and coping strategies experienced by maritime pilots when on-shift. Fifty maritime pilots were recruited via an advertisement in the national association's quarterly newsletter (Mage = 51.42; SD = 9.81). Participants responded to a modified version of the questionnaire used with aviation pilots that assessed overall fatigue, and the symptoms pilots associated with fatigue on duty. Methods pilots used to cope with fatigue before shift and when on the bridge were also assessed. There were significant effects for pilot vitality on 4 categories of fatigue: cognitive dysfunction; emotional disturbance; mean physical effects; and sleepiness. There were no significant effects for vitality on any of the self-reported coping strategy factors. The findings indicated that maritime pilots experience a variety of physical, behavioural, and cognitive fatigue symptoms when on shift. Some of these symptoms are similar to those reported by aviation pilots. However, unlike aviation pilots, maritime pilots reported utilising self-sufficient coping strategies to deal with the experience of fatigue.

Bottoms, Kate; Dewey, Cate; Richardson, Karen; Poljak, Zvonimir

2015-01-01

This study explored potential biosecurity issues related to the delivery of feed to commercial farms. A pilot study was conducted to collect information about the day-to-day feed delivery, including biosecurity concerns at the level of the feed truck, the driver, and the farm. In addition, a reusable rubber boot was tested in an effort to increase the proportion of farms at which truck drivers wore clean footwear, and to explore an alternative to the standard plastic disposable boots that may be unsafe in winter conditions. Most farms did well in terms of proper dead-stock management and keeping the farm lane and feed bin areas clean. The provision of reusable rubber boots significantly increased the proportion of deliveries in which the driver wore clean footwear. PMID:25969585

Background: Traffic volume and speed is going to be increased in Indian Railways successively, leading to higher stress in staff connected with train operations. The jobs of railway engine pilots come under the category of high-strain jobs, necessitating a need to conduct multicentric study to unfold the factors associated with occupational stress and organizational strategies. Materials and Methods: Present study covered 185 railway engine pilots and office clerks working in various railway zones by incidental method. Occupational Stress Index (OSI) test developed by Srivastva and Singh, questionnaire of specific stressors constructed by authors and laboratory test battery for psychological screening of high-speed train pilots were used as tools. Results: Means of OSI and all the 12 occupational stressors of railway engine pilots were found significantly higher to that of office clerks. Means of OSI and occupational stressors of goods train pilots were significantly higher in comparison to high-speed train pilots and passenger train pilots. Study revealed positive correlation of speed perception and complex reaction time tests and negative correlation of other constituent tests of laboratory test battery to OSI test. Highest subgroup of stressor observedwas role overload followed by role conflict. Conclusions: These findings provide a prima facie evidence of higher occupational stress among railway engine pilots because of identified specific stressors prevalent in their job and explore the possible intervention strategies for its reduction. Significant correlation is noticed between OSI and laboratory test results, indicating its relevant utility in preliminary psychological screening. PMID:21808497

2017-01-01

An experiment investigated the impact of normobaric hypoxia induction on aircraft pilot performance to specifically evaluate the use of hypoxia as a method to induce mild cognitive impairment to explore human-autonomous systems integration opportunities. Results of this exploratory study show that the effect of 15,000 feet simulated altitude did not induce cognitive deficits as indicated by performance on written, computer-based, or simulated flight tasks. However, the subjective data demonstrated increased effort by the human test subject pilots to maintain equivalent performance in a flight simulation task. This study represents current research intended to add to the current knowledge of performance decrement and pilot workload assessment to improve automation support and increase aviation safety.

2001-01-01

This study provides recommendations to the FAA and to prospective manufacturers based on an exploration of the effects of data link weather displays upon pilot decision performance. An experiment was conducted with twenty-four current instrument rated pilots who were divided into two equal groups and presented with a challenging but realistic flight scenario involving weather containing significant embedded convective activity. All flights were flown in a full-mission simulation facility within instrument meteorological conditions. The inflight weather display depicted NexRad images, graphical METARs and textual METARs. The objective was to investigate the potential for misuse of a weather display, and incorporate recommendations for the design and use of these displays. The primary conclusion of the study found that the inflight weather display did not improve weather avoidance decision making. Some of the reasons to support this finding include: the pilot's inability to easily perceive their proximity to the storms, increased workload and difficulty in deciphering METAR textual data. The compelling nature of a graphical weather display caused many pilots to reduce their reliance on corroborating weather information from other sources. Minor changes to the weather display could improve the ability of a pilot to make better decisions on hazard avoidance.

Casner, Stephen M.

2003-01-01

Two experiments explored the idea of providing cockpit automation training to airline-bound student pilots using cockpit automation equipment commonly found in small training airplanes. In a first experiment, pilots mastered a set of tasks and maneuvers using a GPS navigation computer, autopilot, and flight director system installed in a small training airplane Students were then tested on their ability to complete a similar set of tasks using the cockpit automation system found in a popular jet transport aircraft. Pilot were able to successfully complete 77% of all tasks in the jet transport on their first attempt. An analysis of a control group suggests that the pilot's success was attributable to the application of automation principles they had learned in the small airplane. A second experiment looked at two different ways of delivering small-aeroplane cockpit automation training: a self-study method, and a dual instruction method. The results showed a slight advantage for the self-study method. Overall, the results of the two studies cast a strong vote for the incorporation of cockpit automation training in curricula designed for pilot who will later transition to the jet fleet.

This pilot study aimed to establish the appropriateness of the Model of Juggling Occupations in exploring the complex experience of role balance amongst working women with family responsibilities living in Perth, Australia. In meeting this aim, an evaluation was conducted of a case study design, where data were collected through a questionnaire, time diary, and interview. Overall role balance varied over time and across participants. Positive indicators of role balance occurred frequently in the questionnaires and time diaries, despite the interviews revealing a predominance of negative evaluations of role balance. Between-role balance was achieved through compatible role overlap, buffering, and renewal. An exploration of within-role balance factors demonstrated that occupational participation, values, interests, personal causation, and habits were related to role balance. This pilot study concluded that the Model of Juggling Occupations is an appropriate conceptual framework to explore the complex and dynamic experience of role balance amongst working women with family responsibilities. It was also confirmed that the case study design, including the questionnaire, time diary, and interview methods, is suitable for researching role balance from this perspective.

The Method of Levels (MOL) is a transdiagnostic cognitive therapy that promotes contentment, wellbeing, and goal achievement through the resolution of internal conflicts underlying psychological distress. MOL, based on Perceptual Control Theory (PCT), was developed in routine clinical practice and has been used effectively across different health services by different practitioners. Access to MOL-style questions through a smartphone app could, potentially, help both the general public maintain robust mental health, and also be a useful adjunct to therapy for clinical populations. The app is called MindSurf because of its focus on helping people explore their thinking. Prior to developing the app and using it with different populations it was necessary to determine whether such an idea would be usable for and acceptable to potential app users. Therefore, a pilot study was conducted with a non-clinical sample to assess the usability and acceptability of the app including monitoring whether the questions delivered in this way were associated with any adverse events. A pilot study using quantitative as well as qualitative methods and incorporating a repeated measures, A-B design was conducted. The 23 participants were healthy adult volunteers who were all either undergraduate students, postgraduate students, or staff of the University of Manchester. They received MOL-style questions on their mobile phones over a 1-week period. Qualitative results were encouraging and indicated that the format and style of questioning were acceptable to participants and did not lead to increased worry or concern. A one-way, repeated measures ANOVA indicated that there was a nonsignificant decrease in scores on the 21-item Depression, Anxiety, and Stress Scale (DASS21) over a 2 week period. The results of the pilot study justified development of MindSurf and further testing once it is available for use. A power analysis indicated that the pilot study was underpowered to detect significant effects but provided important information regarding the appropriate sample size for future research. The pilot study also indicated that future research should investigate the effects of receiving more than three questions per day. Results of the pilot study indicate that MindSurf will be a usable and acceptable app. Its benefits should be further explored through longer studies with larger sample of both the general population as well as clinical populations.

The first steps towards a de minimus, affordable NEA exploration architecture

2013-03-01

The impetus for asteroid exploration is scientific, political, and pragmatic. The notion of sending human explorers to asteroids is not new. Piloted missions to these primitive bodies were first discussed in the 1960s, pairing Saturn V rockets with enhanced Apollo spacecraft to explore what were then called "Earth-approaching asteroids." Two decades ago, NASA's Space Exploration Initiative (SEI) also briefly examined the possibility of visiting these small celestial bodies. Most recently, the US Human Space Flight Review Committee (the second Augustine Commission) suggested that near-Earth objects (NEOs) represent a target-rich environment for exploration via the "Flexible Path" option. However, prior to seriously considering human missions to NEOs, it has become clear that we currently lack a robust catalog of human-accessible targets. The majority of the known NEOs identified by a study team across several NASA centers as "human-accessible" are probably too small and have orbits that are too uncertain to consider mounting piloted expeditions to these small worlds. The first step in developing a comprehensive catalog is, therefore, to complete a space-based NEO survey. The resulting catalog of candidate NEOs would then be transformed into a matrix of opportunities for robotic and human missions for the next several decades and shared with the international community. This initial step of a space-based NEO survey is therefore the linchpin to laying the foundation of a low-risk architecture to venture out and explore these primitive bodies. We suggest such a minimalist framework architecture from (1) extensive ground-based and precursor spacecraft investigations (while applying operational knowledge from science-driven robotic missions), (2) astronaut servicing of spacecraft operating at geosynchronous Earth orbit to retain essential skills and experience, and (3) applying the sum of these skills, knowledge and experience to piloted missions to NEOs.

Hansman, R. John; Pritchett, Amy; Midkiff, Alan

1995-01-01

The perceived importance and utilization of 'party line' information by air carrier flight crews was investigated through pilot surveys and a flight simulation study. The importance, availability, and accuracy of party line information elements were explored through surveys of pilots of several operational types. The survey identified numerous traffic and weather party line information elements which were considered important. These elements were scripted into a full-mission flight simulation which examined the utilization of party line information by studying subject responses to specific information element stimuli. The awareness of the different Party Line elements varied, and awareness was also affected by pilot workload. In addition, pilots were aware of some traffic information elements, but were reluctant to act on Party Line Information alone. Finally, the results of both the survey and the simulation indicated that the importance of party line information appeared to be greatest for operations near or on the airport. This indicates that caution should be exercised when implementing datalink communications in tower and close-in terminal control sectors.

Sadler, Garrett; Battiste, Henri; Ho, Nhut; Hoffmann, Lauren; Lyons, Joseph; Johnson, Walter; Shively, Robert; Smith, David

2016-01-01

We performed a human-in-the-loop study to explore the role of transparency in engendering trust and reliance within highly automated systems. Specifically, we examined how transparency impacts trust in and reliance upon the Autonomous Constrained Flight Planner (ACFP), a critical automated system being developed as part of NASA's Reduced Crew Operations (RCO) Concept. The ACFP is designed to provide an enhanced ground operator, termed a super dispatcher, with recommended diversions for aircraft when their primary destinations are unavailable. In the current study, 12 commercial transport rated pilots who played the role of super dispatchers were given six time-pressured all land scenarios where they needed to use the ACFP to determine diversions for multiple aircraft. Two factors were manipulated. The primary factor was level of transparency. In low transparency scenarios the pilots were given a recommended airport and runway, plus basic information about the weather conditions, the aircraft types, and the airport and runway characteristics at that and other airports. In moderate transparency scenarios the pilots were also given a risk evaluation for the recommended airport, and for the other airports if they requested it. In the high transparency scenario additional information including the reasoning for the risk evaluations was made available to the pilots. The secondary factor was level of risk, either high or low. For high-risk aircraft, all potential diversions were rated as highly risky, with the ACFP giving the best option for a bad situation. For low-risk aircraft the ACFP found only low-risk options for the pilot. Both subjective and objective measures were collected, including rated trust, whether the pilots checked the validity of the automation recommendation, and whether the pilots eventually flew to the recommended diversion airport. Key results show that: 1) Pilots trust increased with higher levels of transparency, 2) Pilots were more likely to verify ACFPs recommendations with low levels of transparency and when risk was high, 3) Pilots were more likely to explore other options from the ACFP in low transparency conditions and when risk was high, and 4) Pilots decision to accept or reject ACFPs recommendations increased as a function of the transparency in the explanation. The finding that higher levels of transparency was coupled with higher levels of trust, a lower need to verify other options, and higher levels of agreement with ACFP recommendations, confirms the importance of transparency in aiding reliance on automated recommendations. Additional analyses of qualitative data gathered from subjects through surveys and during debriefing interviews also provided the basis for new design recommendations for the ACFP.

A pilot study of nursing student's perceptions of academic dishonesty: a generation Y perspective.

As a result of the proliferation of technology, academic dishonesty in colleges and universities is becoming a major global problem of higher education. Unfortunately, it is documented in published research that today's student appears to normalize academic dishonest behaviors. This paper reports on a pilot study that tested an instrument that explored the perceptions of cheating in undergraduate nursing students. The instrument explored scenarios that represented dishonest behaviors in examination situations; dishonest behaviors relevant to classroom assignments; and scenarios that represented dishonest behaviors towards practical laboratory experiences. The participants in this study were quite clear on the definition of academic dishonesty in examination situations but had difficulty identifying academic dishonest behaviors during classroom and laboratory assignments. This paper further discusses these findings from the unique point of view of the characteristics of Generation Yers and the resulting implications for successful strategies that may curtail academic dishonesty.

Accident rates for novice glider pilots vs. pilots with experience.

PubMed

Jarvis, Steve; Harris, Don

2007-12-01

It is a popular notion in gliding that newly soloed pilots have a low accident rate. The intention of this study was to review the support for such a hypothesis from literature and to explore it using UK accident totals and measures of flying exposure. Log sheets from UK gliding clubs were used to estimate flying exposure for inexperienced glider pilots. This was used along with accident data and annual flight statistics for the period 2004-2006 in order to estimate accident rates that could be compared between the pilot groups. The UK accident rate for glider pilots from 2004-2006 was 1 accident in every 3534 launches and 1590 flying hours. The lowest estimated rate for pilots with up to 1 h of experience was 1 accident every 976 launches and 149 h flown. For pilots with up to 10 h of experience the figures were 1 accident in 1274 launches and 503 h. From 2004-2006 UK glider pilots with 10 h or less experience in command had twice the number of accidents per launch and three times as many accidents per hour flown than average for UK glider pilots. Pilots with only 1 h of experience or less were involved in at least 10 times the number of accidents per hour flown than the UK average and had more than 3.5 times the number of accidents per launch.

The purpose of this pilot study was to describe the experiences, support needs, resources, and barriers to support for fathers whose partners had post-partum depression (PPD) in preparation for a larger study. Qualitative methods and community-based research approaches were used in this exploratory/descriptive multi-site study, conducted in New Brunswick and Alberta. Telephone interviews were conducted with a total of 11 fathers in New Brunswick (n= 7) and Alberta (n= 4). Fathers experienced a number of depressive symptoms including: anxiety, lack of time and energy, irritability, feeling sad or down, changes in appetite, and thoughts of harm to self or baby. The most common barriers for fathers were lack of information regarding PPD resources and difficulty seeking support. This pilot study establishes the feasibility of the larger-scale exploration of fathers' experiences in supporting their spouses affected by PPD. © 2010 Blackwell Publishing.

2017-12-15

Flight within degraded visual conditions is a great challenge to pilots of rotary-wing craft. Environmental cues typically used to guide interpretation of speed, location and approach can become obscured, forcing the pilots to rely on data available from in-cockpit instrumentation. To ease the task of flight during degraded visual conditions, pilots require easy access to flight critical information. The current study examined the effect of 'Highways in the Sky' symbology and a conformal virtual pad for landing presented using a Head Up Display (HUD) on pilots' workload and situation awareness for both clear and degraded conditions across a series of simulated rotary-wing approach and landings. Results suggest that access to the HUD lead to significant improvements to pilots' situation awareness, especially within degraded visual conditions. Importantly, access to the HUD facilitated pilot awareness in all conditions. Results are discussed in terms of future HUD development. Practitioner Summary: This paper explores the use of a novel Heads Up Display, to facilitate rotary-wing pilots' situation awareness and workload for simulated flights in both clear and degraded visual conditions. Results suggest that access to HUD facilitated pilots' situation awareness, especially when flying in degraded conditions.

An intervention to improve mental health care for conflict-affected forced migrants in low-resource primary care settings: a WHO MhGAP-based pilot study in Sri Lanka (COM-GAP study)

PubMed Central

2013-01-01

Background Inadequacy in mental health care in low and middle income countries has been an important contributor to the rising global burden of disease. The treatment gap is salient in resource-poor settings, especially when providing care for conflict-affected forced migrant populations. Primary care is often the only available service option for the majority of forced migrants, and integration of mental health into primary care is a difficult task. The proposed pilot study aims to explore the feasibility of integrating mental health care into primary care by providing training to primary care practitioners serving displaced populations, in order to improve identification, treatment, and referral of patients with common mental disorders via the World Health Organization Mental Health Gap Action Programme (mhGAP). Methods/Design This pilot randomized controlled trial will recruit 86 primary care practitioners (PCP) serving in the Puttalam and Mannar districts of Sri Lanka (with displaced and returning conflict-affected populations). The intervention arm will receive a structured training program based on the mhGAP intervention guide. Primary outcomes will be rates of correct identification, adequate management based on set criteria, and correct referrals of common mental disorders. A qualitative study exploring the attitudes, views, and perspectives of PCP on integrating mental health and primary care will be nested within the pilot study. An economic evaluation will be carried out by gathering service utilization information. Discussion In post-conflict Sri Lanka, an important need exists to provide adequate mental health care to conflict-affected internally displaced persons who are returning to their areas of origin after prolonged displacement. The proposed study will act as a local demonstration project, exploring the feasibility of formulating a larger-scale intervention study in the future, and is envisaged to provide information on engaging PCP, and data on training and evaluation including economic costs, patient recruitment, and acceptance and follow-up rates. The study should provide important information on the WHO mhGAP intervention guide to add to the growing evidence base of its implementation. Trial registration SLCTR/2013/025. PMID:24321171

Primary care is often the only available service option for the majority of forced migrants, and integration of mental health into primary care is a difficult task. The proposed pilot study aims to explore the feasibility of integrating mental health care into primary care by providing training to primary care practitioners serving displaced populations, in order to improve identification, treatment, and referral of patients with common mental disorders via the World Health Organization Mental Health Gap Action Programme (mhGAP). This pilot randomized controlled trial will recruit 86 primary care practitioners (PCP) serving in the Puttalam and Mannar districts of Sri Lanka (with displaced and returning conflict-affected populations). The intervention arm will receive a structured training program based on the mhGAP intervention guide. Primary outcomes will be rates of correct identification, adequate management based on set criteria, and correct referrals of common mental disorders. A qualitative study exploring the attitudes, views, and perspectives of PCP on integrating mental health and primary care will be nested within the pilot study. An economic evaluation will be carried out by gathering service utilization information. In post-conflict Sri Lanka, an important need exists to provide adequate mental health care to conflict-affected internally displaced persons who are returning to their areas of origin after prolonged displacement. The proposed study will act as a local demonstration project, exploring the feasibility of formulating a larger-scale intervention study in the future, and is envisaged to provide information on engaging PCP, and data on training and evaluation including economic costs, patient recruitment, and acceptance and follow-up rates. The study should provide important information on the WHO mhGAP intervention guide to add to the growing evidence base of its implementation. SLCTR/2013/025.

A pilot data collecting exercise on stress and nursing students.

PubMed

Por, Jitna

This article discusses the lessons learned from a small pilot study exploring the link between the working environment and occupational stress among groups of nursing students. A comparative descriptive design was adopted to examine, describe and compare the two variables (sources and frequency) in three groups of nursing students. The sample comprised 90 students from one large inner-city school of nursing in London. The Expanded Nursing Stress Scale questionnaires were used to collect the data. The main findings suggest that the adult, child and mental health branch students were similar with respect to overall frequency of occupational stress. Areas of commonality and variability in the sources of stress perceived by the three groups of students were identified. A pilot study is a crucial element of a good study design. Areas of concern, lessons learned and suggested refinements were identified.

High-intensity concurrent training positively affects cardiovascular risk factors. Because this was never investigated in multiple sclerosis, the present pilot study explored the impact of this training on cardiovascular risk factors in this population. Before and after 12 weeks of high-intense concurrent training (interval and strength training, 5 sessions per 2 weeks, n = 16) body composition, resting blood pressure and heart rate, 2-h oral glucose tolerance (insulin sensitivity, glycosylated hemoglobin, blood glucose and insulin concentrations), blood lipids (high- and low-density lipoprotein, total cholesterol, triglyceride levels) and C-reactive protein were analyzed. Twelve weeks of high-intense concurrent training significantly improved resting heart rate (-6%), 2-h blood glucose concentrations (-13%) and insulin sensitivity (-24%). Blood pressure, body composition, blood lipids and C-reactive protein did not seem to be affected. Under the conditions of this pilot study, 12 weeks of concurrent high-intense interval and strength training improved resting heart rate, 2-h glucose and insulin sensitivity in multiple sclerosis but did not affect blood C-reactive protein levels, blood pressure, body composition and blood lipid profiles. Further, larger and controlled research investigating the effects of high-intense concurrent training on cardiovascular risk factors in multiple sclerosis is warranted. Implications for rehabilitation High-intensity concurrent training improves cardiovascular fitness. This pilot study explores the impact of this training on cardiovascular risk factors in multiple sclerosis. Despite the lack of a control group, high-intense concurrent training does not seem to improve cardiovascular risk factors in multiple sclerosis.

Self-regulation workshop and Occupational Performance Coaching with teachers: A pilot study.

PubMed

Hui, Caroline; Snider, Laurie; Couture, Mélanie

2016-04-01

Teachers' occupational role and performance can be undermined when working with students with disruptive classroom behaviours. This pilot study aimed to explore the impact of school-based occupational therapy intervention on teachers' classroom management self-efficacy and perceived performance/satisfaction in their management of students with disruptive behaviours. This pilot study used a multiple-case replication study design. A cohort of regular classroom elementary school teachers (n = 11) participated in a 1-day workshop on sensorimotor strategies for supporting student self-regulation followed by eight individual sessions of Occupational Performance Coaching (OPC). Measurement tools were the Canadian Occupational Performance Measure, Goal Attainment Scaling (GAS), and Teachers' Self-Efficacy Scale-Classroom Management. Improvement in teachers' perception of performance, satisfaction, and classroom management was seen. GAS showed clinically significant improvement. Improvements were sustained at 7 weeks follow-up. Preliminary results support the use of sensorimotor education combined with OPC to enable teachers' occupational performance. © CAOT 2016.

Marchant, David; Sylvester, Jennifer L; Earhart, Gammon M

2010-10-01

This study explored the feasibility and possible benefits of contact improvisation (CI) as an exercise intervention for individuals with PD. This was an uncontrolled pilot study. Eleven people with PD (H&Y=2.4 ± 0.4) participated in a workshop of 10 1.5-h CI classes over 2 weeks, dancing with previously trained student CI dancers. Measures of disease severity, balance, functional mobility, and gait were compared 1 week before and after the workshop. Participants demonstrated improvements on the Unified Parkinson Disease Rating Scale-Motor Subsection and Berg balance scores, along with increased swing and decreased stance percentages during walking. Backward step length also increased. Participants expressed a high level of enjoyment and interest in taking future CI classes. This pilot study supports the feasibility of CI as an intervention to address mobility limitations associated with PD. Copyright © 2010 Elsevier Ltd. All rights reserved.

Quantum Physics Principles and Communication in the Acute Healthcare Setting: A Pilot Study.

PubMed

Helgeson, Heidi L; Peyerl, Colleen Kraft; Solheim-Witt, Marit

This pilot study explores whether clinician awareness of quantum physics principles could facilitate open communication between patients and providers. In the spirit of action research, this study was conceptualized with a holistic view of human health, using a mixed method design of grounded theory as an emergent method. Instrumentation includes surveys and a focus group discussion with twelve registered nurses working in an acute care hospital setting. Findings document that the preliminary core phenomenon, energy as information, influences communication in the healthcare environment. Key emergent themes include awareness, language, validation, open communication, strategies, coherence, incoherence and power. Research participants indicate that quantum physics principles provide a language and conceptual framework for improving their awareness of communication and interactions in the healthcare environment. Implications of this pilot study support the feasibility of future research and education on awareness of quantum physics principles in other clinical settings. Copyright © 2016 Elsevier Inc.

The mechanisms governing calcium fluxes during bone remodeling processes in perimenopausal women are poorly known. Despite higher, albeit erratic, estradiol levels in perimenopause, spine bone loss is greater than during the first five years past the final menstrual flow when estradiol becomes low. Understanding changes during this dynamic transition are important to prevent fragility fractures in midlife and older women. The exploration of long-lived 41Ca (T1/2 = 1.04 × 105 yrs) tracer measurements using accelerator mass spectrometry (AMS) leads to the possibility of monitoring bone remodeling balance. With this new technology, we explored a pilot long-term feasibility study of bone health by measuring the 41Ca trace element in urine for six years from premenopausal to later perimenopausal phases in one midlife woman. We measured bone mineral density in parallel.

Teaching Cockpit Automation in the Classroom

NASA Technical Reports Server (NTRS)

Casner, Stephen M.

2003-01-01

This study explores the idea of teaching fundamental cockpit automation concepts and skills to aspiring professional pilots in a classroom setting, without the use of sophisticated aircraft or equipment simulators. Pilot participants from a local professional pilot academy completed eighteen hours of classroom instruction that placed a strong emphasis on understanding the underlying principles of cockpit automation systems and their use in a multi-crew cockpit. The instructional materials consisted solely of a single textbook. Pilots received no hands-on instruction or practice during their training. At the conclusion of the classroom instruction, pilots completed a written examination testing their mastery of what had been taught during the classroom meetings. Following the written exam, each pilot was given a check flight in a full-mission Level D simulator of a Boeing 747-400 aircraft. Pilots were given the opportunity to fly one practice leg, and were then tested on all concepts and skills covered in the class during a second leg. The results of the written exam and simulator checks strongly suggest that instruction delivered in a traditional classroom setting can lead to high levels of preparation without the need for expensive airplane or equipment simulators.

Exploring the role of children's dreams in psychoanalytic practice today: a pilot study.

PubMed

Lempen, Olivia; Midgley, Nick

2006-01-01

The aim of this research study was to investigate the role of children's dreams in the practice of child psychoanalysis today, and to explore contemporary psychoanalytic understanding of children's dreams. This pilot study consisted of two stages. The first involved a document analysis of published articles in The Psychoanalytic Study of the Child, making a comparison between those of the early 1950s and the 1990s, in order to see in what way the discourse around children's dreams within the psychoanalytic literature has changed over time. The second stage, based on questionnaires and in-depth interviews, attempted to understand in more detail the way contemporary child analysts, working in the Anna Freudian tradition, think about dreams and use them in their clinical practice. Results suggest that there has been a decreased focus on dreams in a clinical context over time, and that this may partly be a consequence of changing theoretical models and changes in training. When work with dreams does take place, it appears that child analysts have

Given the increasing travel of pregnant women from areas were Trypanosoma cruzi is endemic, the congenital transmission of the parasite has become a global public-health problem. In a recent pilot study, which ran in Chile from 2006 to 2010, three strategies for exploring and managing T. cruzi-infected mothers and their infected or uninfected neonates were investigated. Any protocols applied to the investigation of such mother-and-child pairs need to include the detection of infection in pregnant women, the detection of infection, if any, in the children born to the women, the appropriate treatment of the infected neonates, and the serological-parasitological follow-up of all of the neonates until their medical discharge.

Helicopter pilots are involved in a complex multitask activity, implying overuse of cognitive resources, which may result in piloting task impairment or in decision-making failure. Studies usually investigate this phenomenon in well-controlled, poorly ecological situations by focusing on the correlation between physiological values and either cognitive workload or emotional state. This study aimed at jointly exploring workload induced by a realistic simulated helicopter flight mission and emotional state, as well as physiological markers. The experiment took place in the helicopter full flight dynamic simulator. Six participants had to fly on two missions. Workload level, skin conductance, RMS-EMG, and emotional state were assessed. Joint analysis of psychological and physiological parameters associated with workload estimation revealed particular dynamics in each of three profiles. 1) Expert pilots showed a slight increase of measured physiological parameters associated with the increase in difficulty level. Workload estimates never reached the highest level and the emotional state for this profile only referred to positive emotions with low emotional intensity. 2) Non-Expert pilots showed increasing physiological values as the perceived workload increased. However, their emotional state referred to either positive or negative emotions, with a greater variability in emotional intensity. 3) Intermediate pilots were similar to Expert pilots regarding emotional states and similar to Non-Expert pilots regarding physiological patterns. Overall, high interindividual variability of these results highlight the complex link between physiological and psychological parameters with workload, and question whether physiology alone could predict a pilot's inability to make the right decision at the right time.

Introduction of Syphilis Point-of-Care Tests, from Pilot Study to National Programme Implementation in Zambia: A Qualitative Study of Healthcare Workers' Perspectives on Testing, Training and Quality Assurance.

Syphilis affects 1.4 million pregnant women globally each year. Maternal syphilis causes congenital syphilis in over half of affected pregnancies, leading to early foetal loss, pregnancy complications, stillbirth and neonatal death. Syphilis is under-diagnosed in pregnant women. Point-of-care rapid syphilis tests (RST) allow for same-day treatment and address logistical barriers to testing encountered with standard Rapid Plasma Reagin testing. Recent literature emphasises successful introduction of new health technologies requires healthcare worker (HCW) acceptance, effective training, quality monitoring and robust health systems. Following a successful pilot, the Zambian Ministry of Health (MoH) adopted RST into policy, integrating them into prevention of mother-to-child transmission of HIV clinics in four underserved Zambian districts. We compare HCW experiences, including challenges encountered in scaling up from a highly supported NGO-led pilot to a large-scale MoH-led national programme. Questionnaires were administered through structured interviews of 16 HCWs in two pilot districts and 24 HCWs in two different rollout districts. Supplementary data were gathered via stakeholder interviews, clinic registers and supervisory visits. Using a conceptual framework adapted from health technology literature, we explored RST acceptance and usability. Quantitative data were analysed using descriptive statistics. Key themes in qualitative data were explored using template analysis. Overall, HCWs accepted RST as learnable, suitable, effective tools to improve antenatal services, which were usable in diverse clinical settings. Changes in training, supervision and quality monitoring models between pilot and rollout may have influenced rollout HCW acceptance and compromised testing quality. While quality monitoring was integrated into national policy and training, implementation was limited during rollout despite financial support and mentorship. We illustrate that new health technology pilot research can rapidly translate into policy change and scale-up. However, training, supervision and quality assurance models should be reviewed and strengthened as rollout of the Zambian RST programme continues.

Research on staff perception of ethical aspects of psychiatric patient care are scarce; little is known about systematic supplies of ethics support in psychiatric institutions. The goal of this pilot study is to inform the implementation of Clinical Ethics Support Services in psychiatric institutions by assessing which topics of psychiatric practice are considered ethically challenging by the staff. Explorative survey as pilot study by questionnaire with clinical staff, quantitative (descriptive) and qualitative (coding) data-analysis. Involuntary treatment, the relationship between healthcare professionals and patients, staff shortage and the collaboration between the professions as well as dealing with patient relatives came up as ethical challenges. Clinical Ethics Support in psychiatric patient care should not only cover aspects that are specific for psychiatry, but also structural topics such as short resources, interprofessional collaboration and communication with relatives. © Georg Thieme Verlag KG Stuttgart · New York.

Autism and exergaming: effects on repetitive behaviors and cognition.

PubMed

Anderson-Hanley, Cay; Tureck, Kimberly; Schneiderman, Robyn L

2011-01-01

Autism is a neurodevelopmental disorder that leads to impairment in social skills and delay in language development, and results in repetitive behaviors and restricted interests that impede academic and social involvement. Physical exercise has been shown to decrease repetitive behaviors in autistic children and improve cognitive function across the life-span. Exergaming combines physical and mental exercise simultaneously by linking physical activity movements to video game control and may yield better compliance with exercise. In this investigation, two pilot studies explored the potential behavioral and cognitive benefits of exergaming. In Pilot I, twelve children with autism spectrum disorders completed a control task and an acute bout of Dance Dance Revolution (DDR); in Pilot II, ten additional youths completed an acute bout of cyber cycling. Repetitive behaviors and executive function were measured before and after each activity. Repetitive behaviors significantly decreased, while performance on Digits Backwards improved following the exergaming conditions compared with the control condition. Additional research is needed to replicate these findings, and to explore the application of exergaming for the management of behavioral disturbance and to increase cognitive control in children on the autism spectrum.

Minimum Operational Performance Standards (MOPS) are being developed to support the integration of Unmanned Aircraft Systems (UAS) in the National Airspace (NAS). Input from subject matter experts and multiple research studies have informed display requirements for Detect-and-Avoid (DAA) systems aimed at supporting timely and appropriate pilot responses to collision hazards. Phase 1 DAA MOPS alerting is designed to inform pilots if an avoidance maneuver is necessary; the two highest alert levels - caution and warning - indicate how soon pilot action is required and whether there is adequate time to coordinate with the air traffic controller (ATC). Additional empirical support is needed to clarify the extent to which warning-level alerting impacts DAA task performance. The present study explores the differential effects of the auditory and visual cues provided by the DAA Warning alert, and performance implications compared to caution-only alerting are discussed.

A model for the pilot's use of motion cues in roll-axis tracking tasks

Simulated target-following and disturbance-regulation tasks were explored with subjects using visual-only and combined visual and motion cues. The effects of motion cues on task performance and pilot response behavior were appreciably different for the two task configurations and were consistent with data reported in earlier studies for similar task configurations. The optimal-control model for pilot/vehicle systems provided a task-independent framework for accounting for the pilot's use of motion cues. Specifically, the availability of motion cues was modeled by augmenting the set of perceptual variables to include position, rate, acceleration, and accleration-rate of the motion simulator, and results were consistent with the hypothesis of attention-sharing between visual and motion variables. This straightforward informational model allowed accurate model predictions of the effects of motion cues on a variety of response measures for both the target-following and disturbance-regulation tasks.

Arsenic exposure has been associated with low birth weight. However, the underlying mechanisms are not well understood. Alterations to metabolites may act as causal mediators of the effect of arsenic exposure on low birth weight. This pilot study aimed to explore the role of metabolites in mediating the association of arsenic exposure on infant birth weight. Study samples were selected from a well-established prospectively enrolled cohort in Bangladesh comprising 35 newborns and a subset of 20 matched mothers. Metabolomics profiling was performed on 35 cord blood samples and 20 maternal peripheral blood samples collected during the second trimester of pregnancy. Inorganic arsenic (iAs) exposure was evaluated via cord blood samples and maternal toenail samples collected during the first trimester. Multiple linear regression and mediation analyses were used to explore the relationship between iAs exposure, metabolite alterations, and low birth weight. Cord blood arsenic level was correlated with elevated levels of 17-methylstearate, laurate (12:0) and 4-vinylphenol sulfate along with lower birth weight. Prenatal maternal toenail iAs level was associated with two peripheral blood metabolites (butyrylqlycine and tartarate), which likely contributed to higher cord blood iAs levels both independently and interactively. Findings of this pilot study indicate that both intrauterine and maternal peripheral blood metabolites appear to influence the toxic effect of inorganic arsenic exposure on low birth weight.

There is a paucity of literature regarding the relationship between the experience of vision loss and depression. Therefore, the current pilot study aimed to explore whether significant differences existed in levels of depression between adults with different vision loss experiences. A group of adults aged between 20 and 65 yr old with irreversible vision loss in a rehabilitation setting was interviewed. Semistructured interviews were conducted in order to explore patients' experience of vision loss. The Center for Epidemiologic Studies Depression Scale (CES-D) was used to assess depressive levels; 39.5% (n = 15) of patients met CES-D criteria for depression. In addition, higher levels of depression (p < 0.05) were identified in patients whose interviews revealed greater self-awareness of impairment, inadequate social support, and longer rehabilitation stay. Current findings draw attention to variables such as self-awareness of impairment and perceived social support and suggest that depression following vision loss may be related to patients' emotional experiences of impairment and adjustment processes.

A convergent parallel mixed method design assessing bereaved parents' experience of research participation. Eleven parents whose child was treated for cancer at The Royal Children's Hospital, Brisbane completed the questionnaire/interview being piloted (n = 8 mothers; n = 3 fathers; >6 months and <6 years bereaved). Of these, eight parents completed the pilot study evaluation questionnaire, providing feedback on their experience of participation. Participants acknowledged the importance of bereaved parents being central to research design and the development of bereavement programs. Sixty-three per cent (n = 5/8) of parents described completion of the questionnaire as 'not at all/a little bit' of a burden. Seventy-five per cent (n = 6/8) of parents opting into the telephone interview described participation as 'not at all/a little bit' of a burden. When considering the latest timeframes for participation in bereavement research 63% (n = 5/8) of parents indicated 'no endpoint.' Findings from the pilot study enabled important adjustments to be made to a large-scale future study. As a research method, pilot studies may be utilized to minimize harm and maximize the potential benefits for vulnerable research participants. A mixed method approach allows researchers to generalize findings to a broader population while also drawing on the depth of the lived experience.

Handling Qualities Evaluation of Pilot Tools for Spacecraft Docking in Earth Orbit

NASA Technical Reports Server (NTRS)

Bilimoria, Karl D.; Mueller, Eric; Frost, Chad

2009-01-01

A new generation of spacecraft is now under development by NASA to replace the Space Shuttle and return astronauts to the Moon. These spacecraft will have a manual control capability for several mission tasks, and the ease and precision with which pilots can execute these tasks will have an important effect on mission risk and training costs. This paper focuses on the handling qualities of a spacecraft based on dynamics similar to that of the Crew Exploration Vehicle, during the last segment of the docking task with a space station in low Earth orbit. A previous study established that handling qualities for this task degrade significantly as the level of translation-into-rotation coupling increases. The goal of this study is to evaluate the efficacy of various pilot aids designed to mitigate the handling qualities degradation caused by this coupling. Four pilot tools were ev adluaetead:d-band box/indicator, flight-path marker, translation guidance cues, and feed-forward control. Each of these pilot tools improved handling qualities, generally with greater improvements resulting from using these tools in combination. A key result of this study is that feedforward control effectively counteracts coupling effects, providing solid Level 1 handling qualities for the spacecraft configuration evaluated.

The document then develops a flexible scenario for exploration and sketches the technological developments needed to carry out the exploration scenario.

Does training on performance based financing make a difference in performance and quality of health care delivery? Health care provider's perspective in Rungwe Tanzania.

PubMed

Manongi, Rachel; Mushi, Declare; Kessy, Joachim; Salome, Saria; Njau, Bernard

2014-04-04

In recent years, Performance Based Financing (PBF); a form of result based financing, has attracted a global attention in health systems in developing countries. PBF promotes autonomous health facilities, motivates and introduces financial incentives to motivate health facilities and health workers to attain pre-determined targets. To achieve this, the Tanzanian government through the Christian Social Services Commission initiated a PBF pilot project in Rungwe district, Mbeya region. Kilimanjaro Christian Medical Center was given the role of training health workers on PBF principles in Rungwe. The aim of this study was to explore health care providers' perception on a three years training on PBF principles in a PBF pilot project at Rungwe District in Mbeya, Tanzania. This was an explorative qualitative study, which took place at Rungwe PBF pilot area in October 2012. Twenty six (26) participants were purposively selected. Six took part in- depth interviews (IDIs) and twenty (20) in the group discussions. Both the IDIs and the GDs explored the perceived benefit and challenges of implementing PBF in their workplace. Data were manually analyzed using content analysis approach. Overall informants had positive perspectives on PBF training. Most of the health facilities were able to implement some of the PBF concepts in their work places after the training, such as developing job descriptions for their staff, creating quarterly business plans for their facilities, costing for their services and entering service agreement with the government, improved record keeping, customer care and involving community as partners in running their facilities. The most common principle of paying individual performance bonuses was mentioned as a major challenge due to inadequate funding and poor design of Rungwe PBF pilot project. Despite poor design and inadequate funding, our findings have shown some promising results after PBF training in the study area. The findings have highlighted the potential of PBF to act as leverage for initiating innovative and proactive actions, which may motivate health personnel performance and quality of care in the study setting with minimal support. However, key policy issues at the national level should be addressed in order to exploit this opportunity.

McKee, M. Diane; Maher, Stacia; Deen, Darwin; Blank, Arthur E.

2010-01-01

PURPOSE To help design effective primary care-based interventions, we explored urban parents’ reactions to a pilot and feasibility study designed to address risk behaviors for obesity among preschool children. METHODS We conducted 3 focus groups (2 in English, 1 in Spanish) to evaluate the pilot intervention. Focus group participants explored the acceptability of the pilot intervention components (completion of a new screening tool for risk assessment, discussion of risk behaviors and behavior change goal setting by physicians, and follow-up contacts with a lifestyle counselor) and the fidelity of the pilot intervention delivery. RESULTS Parents expressed a desire to change behaviors to achieve healthier families. They believed that doctors should increase their focus on healthy habits during visits. Parents were more accepting of nutrition discussions than increasing activity (citing a lack of safe outdoor space) or decreasing sedentary behaviors (citing many benefits of television viewing). Contacts with the lifestyle counselor were described as empowering, with parents noting her focus on strategies to achieve change for the whole family while recognizing that many food behaviors relate to cultural heritage. Parents expressed frustration with physicians for offering advice about changing behavior but not how to achieve it, for dismissing concerns about picky eating or undereating, and in some cases for labels of overweight that they believed were inappropriately applied. CONCLUSIONS Parents welcomed efforts to address family lifestyle change in pediatric visits. The model of physician goal setting with referral for behavior change counseling is highly acceptable to families. Future interventions should acknowledge parental concerns about undereating and perceived benefits of television viewing. PMID:20458109

Effect of Display Color on Pilot Performance and Describing Functions

Chase, Wendell D.

1997-01-01

A study has been conducted with the full-spectrum, calligraphic, computer-generated display system to determine the effect of chromatic content of the visual display upon pilot performance during the landing approach maneuver. This study utilizes a new digital chromatic display system, which has previously been shown to improve the perceived fidelity of out-the-window display scenes, and presents the results of an experiment designed to determine the effects of display color content by the measurement of both vertical approach performance and pilot-describing functions. This method was selected to more fully explore the effects of visual color cues used by the pilot. Two types of landing approaches were made: dynamic and frozen range, with either a landing approach scene or a perspective array display. The landing approach scene was presented with either red runway lights and blue taxiway lights or with the colors reversed, and the perspective array with red lights, blue lights, or red and blue lights combined. The vertical performance measures obtained in this experiment indicated that the pilots performed best with the blue and red/blue displays. and worst with the red displays. The describing-function system analysis showed more variation with the red displays. The crossover frequencies were lowest with the red displays and highest with the combined red/blue displays, which provided the best overall tracking, performance. Describing-function performance measures, vertical performance measures, and pilot opinion support the hypothesis that specific colors in displays can influence the pilots' control characteristics during the final approach.

2002-01-01

This study explored the feasibility of covering nicotine replacement therapy (NRT) and paying for pharmacist-delivered smoking cessation counseling at the time of NRT pick-up for low-income, managed Medicaid and Basic Health Plan (a state insurance program) enrollees. A prospective pilot intervention was used at two community health centers (CHCs) and two community pharmacies. Participants were adult managed-Medicaid or Basic Health Plan enrollees who attended the pilot CHCs and smoked. An innovative insurance benefit that included coverage for NRT and $15 payment to the pharmacist to deliver cessation counseling with each prescription fill. Proportion of eligible patients who used the cessation benefit and patient and pharmacist satisfaction with the intervention. During the 9-month intervention, 32 patients at the pilot clinics were referred for NRT and pharmacist-delivered counseling. This number represented roughly 5% of eligible smokers. Of these, 26 received NRT with concomitant pharmacist-delivered cessation counseling at least once. Recipients reported a high level of satisfaction with this intervention. Pharmacists indicated they would continue providing counseling if reimbursement remained adequate and if counseling lasted no longer than 5-10 min. However, 12 (38%) who were referred were no longer insured by the sponsoring plan by the end of the 9-month pilot period. Pharmacist-delivered cessation counseling may be feasible and merits further study. More importantly, this pilot reveals two key obstacles in our low-income, culturally diverse setting: low participation and rapid turnover of insureds. Future interventions will need to address these barriers.

The social context of the aeronautical education experience of African-American civilian, commercial, and military pilots

NASA Astrophysics Data System (ADS)

Walker, Taurean Mashawn

The purpose of this research is to explore the social context (the nature and cultural environment) of the aeronautical training experience of African-American civilian, commercial, and military pilots. This research highlights the challenges African-American pilots are exposed to in addition to drawing parallels between the social context and the obstacles they are subjected to along the way. This study is valuable for stakeholders, African-American pilot aspirants, aviation corporations, Federal Aviation Administration, flight schools - in the aviation industry in understanding ways to initiate a paradigm shift and increase awareness about representation and participation of African-American aviation professionals. The qualitative approach was selected to gather a better understanding of the sociological hurdles black aviators face while going through the journey of becoming a pilot. Hardiman (2010) states, "While quantitative research is valuable, qualitative research provides the researcher the ability to view real world situations as they naturally unfold" ( p. 25). According to OBAP (2014), less than 2% of pilots in the United States are African-American. The experiences shared by the participants can provide helpful insight of possible policy implications for the aeronautical industry. There were three research questions in the study: 1) What factors hindered pilot training? 2) What were the resilience factors experienced during pilot training? 3) What were the defining features of the social context surrounding pilot training? Semi-structured, face-to-face interviews were conducted of six professional pilots. A qualitative data analysis was conducted to illustrate the context of the social challenges during the course of pilot training. Three themes were revealed: 1) access, 2) perception of inferiority, and 3) support. Implications of the significance of providing social networks to expose African-Americans to aviation were discussed. Additional means of access and exposure of African-Americans to aviation is essential for further research.

Terminal Area Procedures for Paired Runways

NASA Technical Reports Server (NTRS)

Lozito, Sandy

2011-01-01

Parallel Runway operations have been found to increase capacity within the National Airspace (NAS) however, poor visibility conditions reduce this capacity [1]. Much research has been conducted to examine the concepts and procedures related to parallel runways however, there has been no investigation of the procedures associated with the strategic and tactical pairing of aircraft for these operations. This study developed and examined the pilot and controller procedures and information requirements for creating aircraft pairs for parallel runway operations. The goal was to achieve aircraft pairing with a temporal separation of 15s(+/- 10s error) at a coupling point that is about 12 nmi from the runway threshold. Two variables were explored for the pilot participants: Two levels of flight deck automation (current-day flight deck automation, and a prototype future automation) as well as two flight deck displays that assisted in pilot conformance monitoring. The controllers were also provided with automation to help create and maintain aircraft pairs. Data showed that the operations in this study were found to be acceptable and safe. Workload when using the pairing procedures and tools was generally low for both controllers and pilots, and situation awareness (SA) was typically moderate to high. There were some differences based upon the display and automation conditions for the pilots. Future research should consider the refinement of the concepts and tools for pilot and controller displays and automation for parallel runway concepts.

A pilot study to explore the feasibility of using theClinical Care Classification System for developing a reliable costing method for nursing services.

PubMed

Dykes, Patricia C; Wantland, Dean; Whittenburg, Luann; Lipsitz, Stuart; Saba, Virginia K

2013-01-01

While nursing activities represent a significant proportion of inpatient care, there are no reliable methods for determining nursing costs based on the actual services provided by the nursing staff. Capture of data to support accurate measurement and reporting on the cost of nursing services is fundamental to effective resource utilization. Adopting standard terminologies that support tracking both the quality and the cost of care could reduce the data entry burden on direct care providers. This pilot study evaluated the feasibility of using a standardized nursing terminology, the Clinical Care Classification System (CCC), for developing a reliable costing method for nursing services. Two different approaches are explored; the Relative Value Unit RVU and the simple cost-to-time methods. We found that the simple cost-to-time method was more accurate and more transparent in its derivation than the RVU method and may support a more consistent and reliable approach for costing nursing services.

An empirical evaluation of graphical interfaces to support flight planning

NASA Technical Reports Server (NTRS)

Smith, Philip J.; Mccoy, Elaine; Layton, Chuck; Bihari, Tom

1995-01-01

Whether optimization techniques or expert systems technologies are used, the underlying inference processes and the model or knowledge base for a computerized problem-solving system are likely to be incomplete for any given complex, real-world task. To deal with the resultant brittleness, it has been suggested that 'cooperative' rather than 'automated' problem-solving systems be designed. Such cooperative systems are proposed to explicitly enhance the collaboration of people and the computer system when working in partnership to solve problems. This study evaluates the impact of alternative design concepts on the performance of airline pilots interacting with such a cooperative system designed to support enroute flight planning. Thirty pilots were studied using three different versions of the system. The results clearly demonstrate that different system design concepts can strongly influence the cognitive processes of users. Indeed, one of the designs studied caused four times as many pilots to accept a poor flight amendment. Based on think-aloud protocols, cognitive models are proposed to account for how features of the computer system interacted with specific types of scenarios to influence exploration and decision-making by the pilots. The results are then used to develop recommendations for guiding the design of cooperative systems.

To identify the barriers and facilitators of doctors' engagement with clinical audit and to explore how and why these factors influenced doctors' decisions to engage with the NHS National Clinical Audit Programme. A single-embedded case study. Mixed methods sequential approach with explorative pilot study and follow-up survey. Pilot study comprised 13 semi-structured interviews with purposefully selected consultant doctors over a six-month period. Interview data coded and analysed using directed thematic content analysis with themes compared against the study's propositions. Themes derived from the pilot study informed the online survey question items. Exploratory factor analysis using STATA and descriptive statistical methods applied to summarise findings. Data triangulation techniques used to corroborate and validate findings across the different methodological techniques. NHS National PET-CT Clinical Audit Programme. Doctors reporting on the Audit Programme. Extent of engagement with clinical audit, factors that influence engagement with clinical audit. Online survey: 58/59 doctors responded (98.3%). Audit was found to be initially threatening (79%); audit was reassuring (85%); audit helped validate professional competence (93%); participation in audit improved reporting skills (76%). Three key factors accounted for 97.6% of the variance in survey responses: (1) perception of audit's usefulness, (2) a common purpose, (3) a supportive blame free culture of trust. Factor 1 influenced medical engagement most. The study documents performance feedback as a key facilitator of medical engagement with clinical audit. It found that medical engagement with clinical audit was associated with reduced levels of professional anxiety and higher levels of perceived self-efficacy.

INVESTIGATE-I (INVasive Evaluation before Surgical Treatment of Incontinence Gives Added Therapeutic Effect?): study protocol for a mixed methods study to assess the feasibility of a future randomised controlled trial of the clinical utility of invasive urodynamic testing

PubMed Central

2011-01-01

Background Urinary incontinence is an important health problem to the individual sufferer and to health services. Stress and stress predominant mixed urinary incontinence are increasingly managed by surgery due to advances in surgical techniques. Despite the lack of evidence for its clinical utility, most clinicians undertake invasive urodynamic testing (IUT) to confirm a functional diagnosis of urodynamic stress incontinence before offering surgery for this condition. IUT is expensive, embarrassing and uncomfortable for women and carries a small risk. Recent systematic reviews have confirmed the lack of high quality evidence of effectiveness. The aim of this pilot study is to test the feasibility of a future definitive randomised control trial that would address whether IUT alters treatment decisions and treatment outcome in these women and would test its clinical and cost effectiveness. Methods/design This is a mixed methods pragmatic multicentre feasibility pilot study with four components:- (a) A multicentre, external pilot randomised trial comparing basic clinical assessment with non-invasive tests and IUT. The outcome measures are rates of recruitment, randomisation and data completion. Data will be used to estimate sample size necessary for the definitive trial. (b) Qualitative interviews of a purposively sampled sub-set of women eligible for the pilot trial will explore willingness to participate, be randomised and their overall trial experience. (c) A national survey of clinicians to determine their views of IUT in this context, the main outcome being their willingness to randomise patients into the definitive trial. (d) Qualitative interviews of a purposively sampled group of these clinicians will explore whether and how they use IUT to inform their decisions. Discussion The pilot trial will provide evidence of feasibility and acceptability and therefore inform the decision whether to proceed to the definitive trial. Results will inform the design and conduct of the definitive trial and ensure its effectiveness in achieving its research aim.

Multimegawatt electric propulsion system design considerations

NASA Technical Reports Server (NTRS)

Gilland, J. H.; Myers, Roger M.; Patterson, Michael J.

1991-01-01

Piloted Mars Mission Requirements of relatively short trip times and low initial mass in Earth orbit as identified by the NASA Space Exploration Initiative, indicate the need for multimegawatt electric propulsion systems. The design considerations and results for two thruster types, the argon ion, and hydrogen magnetoplasmadynamic thrusters, are addressed in terms of configuration, performance, and mass projections. Preliminary estimates of power management and distribution for these systems are given. Some assessment of these systems' performance in a reference Space Exploration Initiative piloted mission are discussed. Research and development requirements of these systems are also described.

The "killing zone" revisited: serial nonlinearities predict general aviation accident rates from pilot total flight hours.

PubMed

Knecht, William R

2013-11-01

Is there a "killing zone" (Craig, 2001)-a range of pilot flight time over which general aviation (GA) pilots are at greatest risk? More broadly, can we predict accident rates, given a pilot's total flight hours (TFH)? These questions interest pilots, aviation policy makers, insurance underwriters, and researchers alike. Most GA research studies implicitly assume that accident rates are linearly related to TFH, but that relation may actually be multiply nonlinear. This work explores the ability of serial nonlinear modeling functions to predict GA accident rates from noisy rate data binned by TFH. Two sets of National Transportation Safety Board (NTSB)/Federal Aviation Administration (FAA) data were log-transformed, then curve-fit to a gamma-pdf-based function. Despite high rate-noise, this produced weighted goodness-of-fit (Rw(2)) estimates of .654 and .775 for non-instrument-rated (non-IR) and instrument-rated pilots (IR) respectively. Serial-nonlinear models could be useful to directly predict GA accident rates from TFH, and as an independent variable or covariate to control for flight risk during data analysis. Applied to FAA data, these models imply that the "killing zone" may be broader than imagined. Relatively high risk for an individual pilot may extend well beyond the 2000-h mark before leveling off to a baseline rate. Published by Elsevier Ltd.

Perceptions About Hospice From a Community-Based Pilot Study: Lessons and Findings

PubMed Central

Van Dussen, Daniel; Culler, Krystal L.; Cagle, John G.

2016-01-01

Research investigating the knowledge and attitudes of diverse older adults about hospice care and end-of-life issues is needed to expand service utilization. This pilot study explored an urban area’s perceptions and awareness of hospice through local churches. The sample consisted of 148 adults age 43 and older. Although recruitment efforts resulted in a relatively homogenous sample, findings suggest a lack of knowledge about whether hospice is covered by Medicare, Medicaid, or private insurance. Perceptions of the expense of hospice, however, were not associated with knowledge of coverage. Respondents generally agreed that hospice is important and would recommend its services for their family members. PMID:21208898

The policy work of piloting: Mobilising and managing conflict and ambiguity in the English NHS.

2017-04-01

In spite of their widespread use in policy making in the UK and elsewhere, there is a relatively sparse literature specifically devoted to policy pilots. Recent research on policy piloting has focused on the role of pilots in making policy work in accordance with national agendas. Taking this as a point of departure, the present paper develops the notion of pilots doing policy work. It does this by situating piloting within established theories of policy formulation and implementation, and illustrating using an empirical case. Our case is drawn from a qualitative policy ethnography of a local government pilot programme aiming to extend access to healthcare services. Our case explores the collective entrepreneurship of regional policy makers together with local pilot volunteers. We argue that pilots work to mobilise and manage the ambiguity and conflict associated with particular policy goals, and in their structure and design, shape action towards particular outcomes. We conclude with a discussion of the generative but managed role which piloting affords to local implementers. Copyright © 2017 The Authors. Published by Elsevier Ltd.. All rights reserved.

Johnny was here: From airmanship to airlineship.

PubMed

Haavik, Torgeir K; Kongsvik, Trond; Bye, Rolf Johan; Dalseth Røyrvik, Jens Olgard; Almklov, Petter Grytten

2017-03-01

In this article we explore the phenomenon of airmanship in commercial passenger flights, in a context of increasing standardisation of procedures and technologies. Through observation studies in cockpits and interviews we have studied pilots' practices and how they relate to the larger system of procedures and the technical environment. We find that practices are to a large extent guided by standard operating procedures, and that interchangeability of pilots and aircrafts is both a prerequisite for and enabled by this standardised regime. However, since sociotechnical systems in general - and operation of aircrafts is no exception - are inherently underspecified, the pilots' exercise of discretion in their context-sensitive adaptation of the procedures and technical environments is another prerequisite for well-functioning systems. Mastering these adaptations - and recognising the absolute delimitations of adaptations - is a central aspect of airmanship. Outside this space of manoeuvre for the pilots, the aircrafts are managed by what we call airlineship: The inter-organisational efforts to create predictability and safe practices through de-identification and interchangeability of personnel and aircrafts. Pilots are actors in sociotechnical systems that are not demarcated by the cockpits. To understand pilots' work, studies must account also for the wider sociotechnical context of organisational, regulative and techno-material structures. The article is a contribution to the a generic attempt in the field of ergonomics to contribute with models and theories that portray individuals, groups, organisations and systems in ways that keep sight of the individuals in the systems and the systems in the individuals at the same time.

Well Clear: General Aviation and Commercial Pilots' Perceptioin of Unmanned Aerial Vehicles in the National Airspace System

NASA Technical Reports Server (NTRS)

Ott, Joseph

2015-01-01

This research explored how different pilots perceived the concept of the Well Clear Boundary (WCB) and observed if that boundary changed when dealing with manned versus unmanned aircraft systems (UAS), and the effects of other variables. Pilots' WCB perceptions were collected objectively through simulator recordings and subjectively through questionnaires. Objectively, significant differences were found in WCB perception between two pilot types (general aviation [GA], and Airline Transport Pilots [ATPs]), and significant WCB differences were evident when comparing two intruder types (manned versus unmanned aircraft). Differences were dependent on other manipulated variables (intruder approach angle, ownship speed, and background traffic levels). Subjectively, there were differences in WCB perception across pilot types; GA pilots trusted UAS aircraft higher than the more experienced ATPs. Conclusions indicate pilots' WCB mental models are more easily perceived as time-based boundaries in front of ownship, and more easily perceived as distance-based boundaries to the rear of ownship.

Mothers often serve as the "gatekeepers" of food and the eating experience for young children in the home. Children of different ethnic/racial groups have different obesity prevalence rates, but little is known about how mothers of these groups interpret or implement common childhood obesity prevention messages. The purpose of this mixed methods pilot study was to explore comprehension and implementation of common childhood obesity prevention messages and to identify feeding styles among low-income mothers of young children. White, black, and Hispanic low-income mothers (n=30) of children ages 3-10 were recruited from Indiana. Mothers were interviewed individually regarding the perception and implementation of eight commonly used nutrition and/or physical activity messages. Other outcomes included the results of the Caregiver Feeding Styles Questionnaire and self-reported weight of mothers and child(ren). Interviews were analyzed using thematic analysis to find common themes among the different ethnic/racial groups. Childhood obesity prevention messages were often interpreted or implemented differently among the different ethnic/racial groups. For example, white mothers cited control as a means to manage a child's weight more often compared to the other racial/ethnic groups, whereas black and Hispanic mothers reported catering to a child's preference more frequently compared to white mothers. The pilot study provides evidence that it may be prudent to tailor nutrition messages to mothers of different ethnic/racial backgrounds during nutrition education.

2018-03-01

Through utilizing the technology of compressive sensing (CS), the channel estimation methods can achieve the purpose of reducing pilots and improving spectrum efficiency. The channel estimation and pilot design scheme are explored during the correspondence under the help of block-structured CS in massive MIMO systems. The block coherence property of the aggregate system matrix can be minimized so that the pilot design scheme based on stochastic search is proposed. Moreover, the block sparsity adaptive matching pursuit (BSAMP) algorithm under the common sparsity model is proposed so that the channel estimation can be caught precisely. Simulation results are to be proved the proposed design algorithm with superimposed pilots design and the BSAMP algorithm can provide better channel estimation than existing methods.

To explore online study groups as augmentation tools in preparing for the Royal Australian and New Zealand College of Psychiatrists Observed Structured Clinical Examinations (OSCE) for fellowship. An online survey of New Zealand trainees was carried out to assess exam preparedness and openness to virtual study groups and results analysed. Relevant material around virtual study groups for fellowship examinations was reviewed and used to inform a pilot virtual study group. Four New Zealand trainees took part in the pilot project, looking at using a virtual platform to augment OSCE preparation. Of the 50 respondents 36% felt adequately prepared for the OSCE. Sixty-four per cent were interested in using a virtual platform to augment their study. Virtual study groups were noted to be especially important for rural trainees, none of whom felt able to form study groups for themselves. The pilot virtual study group was trialled successfully. All four trainees reported the experience as subjectively beneficial to their examination preparation. Virtual platforms hold promise as an augmentation strategy for exam preparation, especially for rural trainees who are more geographically isolated and less likely to have peers preparing for the same examinations.

Explore the different vestibular physiologic response retention patterns after Coriolis acceleration training in student pilots and extend the results for use with Chinese astronauts in the future. Twelve healthy control male subjects were screened from males familiar with vestibular training and who physically resembled the astronauts. Fourteen student pilots were selected from 23 participants by rotational vestibular function tests. All subjects were exposed to five-day continuous or intermittent Coriolis acceleration training. Subjective motion sickness (MS) symptom scores, electrocardiography, electrogastrography (EGG), post-rotatory nystagmus and renin-angiotensin system responses were measured before, during and after rotational vestibular function tests at different times after vestibular training. Subjects could tolerate 10 min or 15 min of vestibular with mild MS symptoms. Retention of vestibular autonomic responses (retention of MS symptom scores, heart rate variability, power density of EGG, variations in levels of arginine vasopressin) were approximately 1 week for control subjects and approximately 5 weeks for student pilots. Decreases in slow-phase velocity of post-rotatory nystagmus were maintained for 14 weeks for control subjects and 9 weeks for student pilots. Retention of the vestibulo-autonomic reaction after vestibular training was different for control subjects and student pilots. All parameters related to autonomic responses could be maintained at low levels after vestibular training for approximately 1 week for control subjects and approximately 5 weeks for student pilots. Uncoupling patterns between post-rotatory nystagmus and the vestibulo-autonomic reaction may be helpful in the design of clinical rehabilitation plans for balance-disorder patients and for exploration of artificial gravity in future space missions.

Novacek, Paul F.; Burgess, Malcolm A.; Heck, Michael L.; Stokes, Alan F.; Stough, H. Paul, III (Technical Monitor)

2001-01-01

A two-phase experiment was conducted to explore the effects of data-link weather displays upon pilot decision performance. The experiment was conducted with 49 instrument rated pilots who were divided into four groups and placed in a simulator with a realistic flight scenario involving weather containing convective activity. The inflight weather display depicted NEXRAD images, with graphical and textual METARs over a moving map display. The experiment explored the effect of weather information, ownship position symbology and NEXRAD cell size resolution. The phase-two experiment compared two groups using the data-linked weather display with ownship position symbology. These groups were compared to the phase-one group that did not have ownship position symbology. The phase-two pilots were presented with either large NEXRAD cell size (8 km) or small cell size (4 km). Observations noted that the introduction of ownship symbology did not appear to significantly impact the decision making process, however, the introduction of ownship did reduce workload. Additionally, NEXRAD cell size resolution did appear to influence the tactical decision making process.

(v.k.pearson@open.ac.uk Fax: +44 (0) 858022 Phone: +44 (0) 1908652814 The Rocks From Space (RFS) project is a PPARC and Open University supported planetary science outreach initiative. It capitalises on the successes of Open University involvement in recent space missions such as Genesis and Stardust which have brought planetary science to the forefront of public attention.Our traditional methods of planetary science outreach have focussed on activities such as informal school visits and public presentations. However, these traditional methods are often limited to a local area to fit within time and budget constraints and therefore RFS looks to new technologies to reach geographically dispersed audiences. In collaboration with Stockton-on-Tees City Learning Centre, we have conducted a pilot study into the use of Virtual Learning Environments (VLEs) for planetary science outreach. The pilot study was undertaken under the guise of a "Space Safari" in which pupils dispersed across the Teesside region of the UK could collaboratively explore the Solar System. Over 300 students took part in the pilot from 11 primary schools (ages 6-10). Resources for their exploration were provided by Open University scientists in Milton Keynes and hosted on the VLE. Students were encouraged to post their findings, ideas and questions via wikis and a VLE forum. This combination of contributions from students, teachers and scientists encouraged a collaborative learning environment. These asynchronous activities were complemented by synchronous virtual classroom activities using Elluminate Live! facilities where students could attend "drop-in" sessions with scientists to discuss their exploration. Following these activities, schools were asked to produce a collaborative piece of work about their exploration that could be hosted on the Rocks From Space website (www.rocksfromspace.open.ac.uk; designed by Milton Keynes HE college students) as a resource for future projects and wider public access. Submissions included powerpoint presentations, animations, poems and murals and illustrates the cross curriculum nature of this project. We present the outcomes and evaluation of this pilot study with recommendations for the future use of VLEs in planetary science outreach.

Objective. To assess a text messaging intervention to promote tuberculosis (TB) treatment adherence. Methods. A mixed-methods pilot study was conducted within a public pulmonary-specialized hospital in Argentina. Patients newly diagnosed with TB who were 18 or older, and had mobile phone access were recruited and randomized to usual care plus either medication calendar (n = 19) or text messaging intervention (n = 18) for the first two months of treatment. Primary outcomes were feasibility and acceptability; secondary outcomes explored initial efficacy. Results. Feasibility was evidenced by high access to mobile phones, familiarity with texting, most phones limited to basic features, a low rate of participant refusal, and many describing suboptimal TB understanding. Acceptability was evidenced by participants indicating feeling cared for, supported, responsible for their treatment, and many self-reporting adherence without a reminder. Participants in the texting group self-reported adherence on average 77% of the days whereas only 53% in calendar group returned diaries. Exploring initial efficacy, microscopy testing was low and treatment outcomes were similar in both groups. Conclusion. The texting intervention was well accepted and feasible with greater reporting of adherence using text messaging than the diary. Further evaluation of the texting intervention is warranted.

1992-01-01

In response to the Report of the Advisory Committee on the future of the U.S. Space Program and a request from NASA's Exploration Office, the MIT Hunsaker Aerospace Corporation (HAC) conducted a feasibility study, known as Project Columbiad, on reestablishing human presence on the Moon before the year 2000. The mission criteria established were to transport a four person crew to the lunar surface at any latitude and back to Earth with a 14-28 day stay on the lunar surface. Safety followed by cost of the Columbiad Mission were the top level priorities of HAC. The resulting design has a precursor mission that emplaces the required surface payloads before the piloted mission arrives. Both the precursor and piloted missions require two National Launch System (NLS) launches. Both the precursor and piloted mission have an Earth orbit rendezvous (EOR) with a direct transit to the Moon post-EOR. The piloted mission returns to Earth via a direct transit. Included among the surface payloads preemplaced are a habitat, solar power plant (including fuel cells for the lunar night), lunar rover, and mechanisms used to cover the habitat with regolith (lunar soil) in order to protect the crew members from severe solar flare radiation.

Breakthrough Listen on MWA Pilot Study

Croft, S.; Siemion, A.; Kaplan, D. L.; Tremblay, S.

2016-07-01

We propose a pilot study, using the Voltage Capture System, for Breakthrough Listen on the MWA. Breakthrough Listen (BL) is a major new project that aims to dramatically improve the coverage of parameter space in the search for intelligent life beyond Earth. BL has already deployed hardware and software to the Green Bank Telescope, and will bring a similar program with the Parkes Telescope online in the second half of 2016. The low frequency sky is however currently very poorly explored. The superb capabilities of the MWA (large field of view, low frequency of operation, and location in a very radio quiet site) provide a unique opportunity for a pilot study to obtain voltage data for a SETI (Search For Extraterrestrial Intelligence) study of the Galactic Plane. We propose commensal observations, piggybacking on the proposed pulsar search of Tremblay et al. Using existing VCS software, combined with the pipeline developed for Breakthrough Listen at GBT and Parkes, we will perform a blind search for candidate signals from extraterrestrial intelligence. Although the chances of a detection are not large, particularly for a pilot study such as that proposed here, the Breakthrough Listen team plan to perform extensive testing and analysis on the data obtained which should be useful for other users of the MWA VCS. We will make the secondary SETI data products and associated documentation available as a resource to the community via the Breakthrough Listen online archive.

Parental reflective functioning (PRF) is the capacity to focus on experience and feelings in oneself and in the child. Individual differences in PRF reportedly affect child attachment and socioemotional development. In this study, we report work on developing a questionnaire to assess PRF during pregnancy (Prenatal Parental Reflective Functioning Questionnaire; P-PRFQ). The factor structure of the 33-item version of the P-PRFQ was explored using pilot study data from the Finn Brain Birth Cohort Study (n = 124 mothers, n = 82 fathers). Construct validity was assessed against the Pregnancy Interview (PI; A. Slade, L. Grunebaum, L. Huganir, & M. Reeves, 1987, 2002, 2011) in a subsample of 29 mothers from the same pilot sample. Exploratory and confirmatory factor analysis resulted in a 14-item P-PRFQ, with three factors which seem to capture relevant aspects of prenatal parental mentalization-F1: "Opacity of mental states," F2: "Reflecting on the fetus-child," and F3: "The dynamic nature of the mental states." Functioning of the factor structure was further tested in the large cohort with 600 mothers and 600 fathers. Correlations with the PI result were high, both regarding total and factor scores of the P-PRFQ. Cost-effective tools to assess key areas of early parenting are needed for both research and clinical purposes. The 14-item P-PRFQ seems to be an applicable and promising new tool for assessing very early parental mentalizing capacity. © 2015 Michigan Association for Infant Mental Health.

Intubation after rapid sequence induction performed by non-medical personnel during space exploration missions: a simulation pilot study in a Mars analogue environment.

PubMed

Komorowski, Matthieu; Fleming, Sarah

2015-01-01

The question of the safety of anaesthetic procedures performed by non anaesthetists or even by non physicians has long been debated. We explore here this question in the hypothetical context of an exploration mission to Mars. During future interplanetary space missions, the risk of medical conditions requiring surgery and anaesthetic techniques will be significant. On Earth, anaesthesia is generally performed by well accustomed personnel. During exploration missions, onboard medical expertise might be lacking, or the crew doctor could become ill or injured. Telemedical assistance will not be available. In these conditions and as a last resort, personnel with limited medical training may have to perform lifesaving procedures, which could include anaesthesia and surgery. The objective of this pilot study was to test the ability for unassisted personnel with no medical training to perform oro-tracheal intubation after a rapid sequence induction on a simulated deconditioned astronaut in a Mars analogue environment. The experiment made use of a hybrid simulation model, in which the injured astronaut was represented by a torso manikin, whose vital signs and hemodynamic status were emulated using a patient simulator software. Only assisted by an interactive computer tool (PowerPoint(®) presentation), five participants with no previous medical training completed a simplified induction of general anaesthesia with intubation. No major complication occurred during the simulated trials, namely no cardiac arrest, no hypoxia, no cardiovascular collapse and no failure to intubate. The study design was able to reproduce many of the constraints of a space exploration mission. Unassisted personnel with minimal medical training and familiarization with the equipment may be able to perform advanced medical care in a safe and efficient manner. Further studies integrating this protocol into a complete anaesthetic and surgical scenario will provide valuable input in designing health support systems for space exploration missions.

Spinal cord injury rehabilitation patient and physical therapist perspective: a pilot study.

PubMed

Sliwinski, Martha M; Smith, Ryan; Wood, Andrea

2016-01-01

The objectives of this retrospective observational study were to explore physical therapists' perceived involvement of patients with SCI in physical therapy (PT) rehabilitation, second to explore individuals with SCI perceived involvement in PT rehabilitation, third to compare how patients and physical therapists perceive involvement in PT rehabilitation and last to explore patients' perceived involvement with satisfaction with life (SWL). This study was conducted in the United States. Two 11-item questionnaires were designed one for physical therapists and one for patients. The items were rated on a Likert-type agreement scale. Thirty physical therapists completed the patient involvement questionnaire for physical therapists and nine individuals with SCI completed the patient involvement questionnaire and SWL scale. We certify that all applicable governmental and institutional guidelines were followed during the course of this research. The results indicated that both physical therapists and patients were overall in agreement that patients were involved in their PT rehabilitation on most items. The two items that received the lowest Likert scores by the therapists and patients were friends and family involvement in therapy and gender-related issues. The item, individualized patient goals, received the largest discrepancy between therapists and patients. The sample size was too small to observe a trend with SWL and perceived involvement. Patients and PTs from this pilot overall agree patients are included in treatment; however, the discrepancy in scores related to individualized goals requires further research.

A Pilot Study to Examine the Relationship Between Napping and Fatigue in Nurses Practicing on the Night Shift.

PubMed

Neville, Kathleen; Velmer, Gillian; Brown, Shari; Robol, Nancy

2017-11-01

The aim of this study is to explore the relationship of night-shift napping on fatigue. Nurses' fatigue, especially at night, interferes with quality of life and job performance and impacts safety and health. Night-shift nurses completed the Brief Fatigue Inventory and a demographic information sheet to determine differences in fatigue between nurses who napped during their night shift as compared with nurses who did not nap. No statistically significant differences in global fatigue were found; differences in rotating shift, age, and, gender were identified. Rotating shifts, a 2nd job, and caring for family predicted fatigue. Based on this pilot study, further investigations of fatigue among night-shift nurses are needed as well as evidence-based support to promote sleep.

PubMed

Anderson, Emily E

2013-02-01

When community partners have direct interaction with human research participants, it is important to consider potential threats to participant protections and research integrity. Few studies have directly compared the views of academic and community partners. This pilot focus group study explores the views of academic partners (APs) and community partners (CPs) regarding challenges to the protection of research participants and research integrity in community-engaged research (CEnR). Data are analyzed to understand how APs and CPs define and think about ethical problems and how meaning and analysis may differ between the two groups. Findings have implications for the development of research ethics training materials for academic-community research partnerships and IRBs; best practices for CEnR; and future research on ethical issues in CEnR.

Study of a safety margin system for powered-lift STOL aircraft

NASA Technical Reports Server (NTRS)

Heffley, R. K.; Jewell, W. F.

1978-01-01

A study was conducted to explore the feasibility of a safety margin system for powered-lift aircraft which require a backside piloting technique. The objective of the safety margin system was to present multiple safety margin criteria as a single variable which could be tracked manually or automatically and which could be monitored for the purpose of deriving safety margin status. The study involved a pilot-in-the-loop analysis of several safety margin system concepts and a simulation experiment to evaluate those concepts which showed promise of providing a good solution. A system was ultimately configured which offered reasonable compromises in controllability, status information content, and the ability to regulate the safety margin at some expense of the allowable low speed flight path envelope.

Quality of life in children with epilepsy and cognitive impairment: a review and a pilot study.

2007-01-01

Various methods have recently been proposed to assess the physical, psychological or social dimensions of quality of life (QoL) in children with epilepsy (CwE) and their families. Some methods are based exclusively on parental report and others emphasize the importance of an interview with the patient himself. In children with epilepsy and severe cognitive deficit only parental report is possible in practice; however, some parental based methods to evaluate QoL in CwE have excluded children with cognitive deficit. The present pilot study explores which items are suitable for a parental-based QoL evaluation in CwE and special educational needs, and the most frequently reported parental concerns in this special population of children.

Ross, P; Hubert, J

2017-01-01

Objectives To identify the barriers and facilitators of doctors’ engagement with clinical audit and to explore how and why these factors influenced doctors’ decisions to engage with the NHS National Clinical Audit Programme. Design A single-embedded case study. Mixed methods sequential approach with explorative pilot study and follow-up survey. Pilot study comprised 13 semi-structured interviews with purposefully selected consultant doctors over a six-month period. Interview data coded and analysed using directed thematic content analysis with themes compared against the study’s propositions. Themes derived from the pilot study informed the online survey question items. Exploratory factor analysis using STATA and descriptive statistical methods applied to summarise findings. Data triangulation techniques used to corroborate and validate findings across the different methodological techniques. Setting NHS National PET-CT Clinical Audit Programme. Participants Doctors reporting on the Audit Programme. Main Outcome measures Extent of engagement with clinical audit, factors that influence engagement with clinical audit. Results Online survey: 58/59 doctors responded (98.3%). Audit was found to be initially threatening (79%); audit was reassuring (85%); audit helped validate professional competence (93%); participation in audit improved reporting skills (76%). Three key factors accounted for 97.6% of the variance in survey responses: (1) perception of audit’s usefulness, (2) a common purpose, (3) a supportive blame free culture of trust. Factor 1 influenced medical engagement most. Conclusions The study documents performance feedback as a key facilitator of medical engagement with clinical audit. It found that medical engagement with clinical audit was associated with reduced levels of professional anxiety and higher levels of perceived self-efficacy. PMID:28210493

Group supervision for healthcare professionals within primary care for patients with psychosomatic health problems: a pilot intervention study.

PubMed

Bullington, Jennifer; Cronqvist, Agneta

2018-03-01

In primary health care, efficacious treatment strategies are lacking for these patients, although the most prominent symptoms accounting for consultation in primary care often cannot be related to any biological causes. The aim was to explore whether group supervision from a specific phenomenological theory of psychosomatics could provide healthcare professionals treating patients with psychosomatic health issues within primary care a deeper understanding of these conditions and stimulate profession-specific treatment strategies. Our research questions were as follows: (i) What is the healthcare professionals' understanding of psychosomatics before and after the intervention? (ii) What are the treatment strategies for this group of patients before and after the intervention? The study was an explorative qualitative intervention pilot study. The six participants from a primary healthcare setting in a medium-sized city in Sweden participated in the study. A supervision group was formed, based on a mix of professions, age, gender and years of clinical experience. Supervision consisted of one 75-minutes meeting every month during the course of 6 months. Participants were interviewed before and after the supervision intervention. The study showed two distinct categories emerged from the data. One category of healthcare professionals espoused a psycho-educative approach, while the other lacked a cohesive approach. The supervision improved the second category of healthcare professionals' understanding of psychosomatics. The psycho-educative group did not change their understanding of psychosomatics, although they felt strengthened in their approach by the supervision. Profession-specific strategies were not developed. This pilot study indicates that a relatively short supervision intervention can aid clinicians in their clinical encounters with these patients; however, further research is necessary to ascertain the value of the specific phenomenologically based supervision intervention. © 2017 Nordic College of Caring Science.

Dickinson, Terry L.; Milkulka, Peter J.; Kwan, Doris; Fitzgibbons, Amy A.; Jinadu, Florence R.; Freeman, Frederick G.; Scerbo, Mark W.; Pope, A. T. (Technical Monitor)

2001-01-01

Two studies explored user acceptance of devices that measure hazardous states of awareness. In the first study, critical incident data were collected in two workshops from 11 operators working as air traffic controllers or commercial pilots. These critical incident data were used to develop a survey of the acceptability of awareness measures. In the second study, the survey was administered to 100 people also working as air traffic controllers or commercial pilots. Results show that operators are open to the inclusion of technology to measure HSAs even if that technology is somewhat invasive as long as feedback about the HSAs is considered to be useful and helpful. Nonetheless, a major concern is the legal complications associated with being recorded, particularly for older and more experienced operators. Air traffic controllers emphasized the importance of sharing technology information with supervisors in order to receive backup or assistance under conditions of task overload, whereas pilots emphasized the influence of work schedules on problems with awareness. Recommendations are offered concerning the implementation of devices to measure hazardous states of awareness.

2013-09-01

Training in patient safety is an important element of medical education. Most educational interventions on patient safety training adopt a 'health-professional lens' with limited consideration on the impact of safety lapses on the patient and their families and little or no involvement of patients in the design or delivery of the training. This paper describes a pilot study to test the feasibility and acceptability of implementing a patient-led educational intervention to facilitate safety training amongst newly qualified doctors. Patients and/or carers who had experienced harm during their care shared narratives of their stories with trainees; this was followed by a focused discussion on patient safety issues exploring the causes and consequences of safety incidents and lessons to be learned from these. The intervention, which will be further tested in an NIHR-funded randomised controlled trial (RCT), was successfully implemented into an existing training programme and found acceptance amongst the patients and trainees. The pilot study proved to be a useful step in refining the intervention for the RCT including identifying appropriate outcome measures and highlighting organisational issues.

Purpose Identify facilitators and barriers to physical activity (PA), and explore the utility of Social Cognitive Theory (SCT) and Transactional Model of Stress and Coping (TMSC) in understanding PA behaviour among persons with multiple sclerosis (MS). Methods Thirteen participants from a clinical trial were interviewed and classified as physically active, sometimes active, or inactive based on the Health-Promoting Lifestyle Profile-II. Interviews were analysed using analytical induction, which consisted of coding data into pre-established categories and then exploring similarities and differences between groups. Pre-established coding categories were constructs from SCT (i.e. environment, expectations, self-efficacy, and self-regulation) and TMSC (i.e. stress appraisal and coping style). Results Inactive and active participants differed in their self-regulation skills, self-efficacy, and coping styles. Common barriers to PA included symptoms and the physical and social environment. Facilitators of PA included strong self-regulation skills, confidence to overcome symptoms to engage in PA (i.e. barrier self-efficacy), and positive coping styles. Conclusion Results from this pilot study suggest that PA interventions will need to implement multiple strategies that target self-efficacy, social environment, and coping styles. We found SCT and TMSC useful in understanding PA behaviour among persons with MS; however, a limitation to these theories is that they are not explicit in the relationship between health and cognitions. Future research will need to explore how to incorporate models of health and function into existing behaviour change theories. PMID:19479491

The objective of this analysis is to evaluate the necessity of large clinical trials using FLOW trial data. The FLOW pilot study and definitive trial were factorial trials evaluating the effect of different irrigation solutions and pressures on re-operation. To explore treatment effects over time, we analyzed data from the pilot and definitive trial in increments of 250 patients until the final sample size of 2447 patients was reached. At each increment we calculated the relative risk (RR) and associated 95% confidence interval (CI) for the treatment effect, and compared the results that would have been reported at the smaller enrolments with those seen in the final, adequately powered study. The pilot study analysis of 89 patients and initial incremental enrolments in the FLOW definitive trial favored low pressure compared to high pressure (RR: 1.50, 95% CI: 0.75-3.04; RR: 1.39, 95% CI: 0.60-3.23, respectively), which is in contradiction to the final enrolment, which found no difference between high and low pressure (RR: 1.04, 95% CI: 0.81-1.33). In the soap versus saline comparison, the FLOW pilot study suggested that re-operation rate was similar in both the soap and saline groups (RR: 0.98, 95% CI: 0.50-1.92), whereas the FLOW definitive trial found that the re-operation rate was higher in the soap treatment arm (RR: 1.28, 95% CI: 1.04-1.57). Our findings suggest that studies with smaller sample sizes would have led to erroneous conclusions in the management of open fracture wounds.

Medical educators working abroad: a pilot study of educators' experiences in the Middle East.

PubMed

McLean, Michelle; McKimm, Judy; Major, Stella

2014-09-01

Medical education is now a global enterprise, with many medical educators working internationally, either for short or longer periods or even permanently. In parallel, many medical schools are now involved in collaborations and partnerships with schools in other countries. With this in mind, we set out to explore what motivates, supports and inhibits medical educators who wish to or might work outside their "home country". This article reports on the pilot stage (in specific organizational contexts in Middle East) of a longitudinal project aimed at canvassing medical educators on a broader global scale, using reflective accounts and a questionnaire survey. The findings from this pilot study raise interesting issues about the lived experience of medical educators who have chosen to work in a different culture from their own. Respondents identify many advantages around skills, personal and professional development. Three main issues emerged in terms of educators' experiences: the academic environment, medical practice in a different cultural context and personal matters. Adapting to the local culture, gender segregation and the impact on learning and teaching was an overarching factor. We introduce an explanatory framework to explain the development of international educator identity, a cyclical process in which, through experiences and reflection, individual world views and perspectives are continually modified and developed. This pilot study tested the methodologies and developed a new conceptual model that will be used in a wider study across different cultures.

Display dimensionality and conflict geometry effects on maneuver preferences for resolving in-flight conflicts.

PubMed

Thomas, Lisa C; Wickens, Christopher D

2008-08-01

Two experiments explored the effects of display dimensionality, conflict geometry, and time pressure on pilot maneuvering preferences for resolving en route conflicts. With the presence of a cockpit display of traffic information (CDTI) that provides graphical airspace information, pilots can use a variety of conflict resolution maneuvers in response to how they perceive the conflict. Inconsistent preference findings from previous research on conflict resolution using CDTIs may be attributable to inherent ambiguities in 3-D perspective displays and/or a limited range of conflict geometries. Pilots resolved predicted conflicts using CDTIs with three levels of display dimensionality; the first had two 2-D orthogonal views, the second depicted the airspace in two alternating 3-D perspective views, and the third had a pilot-controlled swiveling viewpoint. Pilots demonstrated the same preferences that have been observed in previous research for vertical over lateral maneuvers in low workload and climbs over descents for level-flight conflicts. With increasing workload the two 3-D perspective displays, but not the 2-D displays, resulted in an increased preference for lateral over vertical maneuvers. Increased time pressure resulted in increased vertical maneuvers, an effect again limited to the two 3-D perspective displays. Resolution preferences were more affected by workload and time pressure when the 3-D perspective displays were used, as compared with the 2-D displays, although overall preferences were milder than in previous studies. Investigating maneuver preferences using the strategic flight planning paradigm employed in this study may be the key to better ensure pilot acceptance of computer-generated resolution maneuvers.

1993-01-01

The Real-Time Data System (RTDS) project is exploring the application of advanced technologies to the real-time flight operations environment of the Mission Control Centers at NASA's Johnson Space Center. The system, based on a network of engineering workstations, provides services such as delivery of real time telemetry data to flight control applications. To automate the operation of this complex distributed environment, a facility called PILOT (Process Integrity Level and Operation Tracker) is being developed. PILOT comprises a set of distributed agents cooperating with a rule-based expert system; together they monitor process operation and data flows throughout the RTDS network. The goal of PILOT is to provide unattended management and automated operation under user control.

 The objective of this study was to compare the closure rate of hemodynamically significant patent ductus arteriosus (hsPDA) of intravenous ibuprofen + paracetamol (acetaminophen) versus ibuprofen + placebo, in preterm infants of 24 to 31 6/7 weeks postmenstrual age.  This is a single-center, double-blind, randomized controlled pilot study. Infants were assigned for treatment with either intravenous ibuprofen + paracetamol ( n  = 12) or ibuprofen + placebo ( n  = 12).  There was no statistical difference in baseline characteristics of the two groups. Echocardiography parameters were comparable before treatment in both groups. There was a trend toward higher hsPDA closure rate in the paracetamol group in comparison to the placebo group (83 vs. 42%, p  = 0.08). No adverse effects, clinical or laboratory, were associated with adding paracetamol.  Our pilot study was unable to detect a beneficial effect by adding intravenous paracetamol to ibuprofen for the treatment of hsPDA. Larger prospective studies are needed to explore the positive tendency suggested by our results and to assure safety. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

Preliminary Exploration of Adaptive State Predictor Based Human Operator Modeling

NASA Technical Reports Server (NTRS)

Trujillo, Anna C.; Gregory, Irene M.

2012-01-01

Control-theoretic modeling of the human operator dynamic behavior in manual control tasks has a long and rich history. In the last two decades, there has been a renewed interest in modeling the human operator. There has also been significant work on techniques used to identify the pilot model of a given structure. The purpose of this research is to attempt to go beyond pilot identification based on collected experimental data and to develop a predictor of pilot behavior. An experiment was conducted to quantify the effects of changing aircraft dynamics on an operator s ability to track a signal in order to eventually model a pilot adapting to changing aircraft dynamics. A gradient descent estimator and a least squares estimator with exponential forgetting used these data to predict pilot stick input. The results indicate that individual pilot characteristics and vehicle dynamics did not affect the accuracy of either estimator method to estimate pilot stick input. These methods also were able to predict pilot stick input during changing aircraft dynamics and they may have the capability to detect a change in a subject due to workload, engagement, etc., or the effects of changes in vehicle dynamics on the pilot.

Evaluating online data of water quality changes in a pilot drinking water distribution system with multivariate data exploration methods.

The distribution of drinking water generates soft deposits and biofilms in the pipelines of distribution systems. Disturbances in water distribution can detach these deposits and biofilms and thus deteriorate the water quality. We studied the effects of simulated pressure shocks on the water quality with online analysers. The study was conducted with copper and composite plastic pipelines in a pilot distribution system. The online data gathered during the study was evaluated with Self-Organising Map (SOM) and Sammon's mapping, which are useful methods in exploring large amounts of multivariate data. The objective was to test the usefulness of these methods in pinpointing the abnormal water quality changes in the online data. The pressure shocks increased temporarily the number of particles, turbidity and electrical conductivity. SOM and Sammon's mapping were able to separate these situations from the normal data and thus make those visible. Therefore these methods make it possible to detect abrupt changes in water quality and thus to react rapidly to any disturbances in the system. These methods are useful in developing alert systems and predictive applications connected to online monitoring.

Schwortz, Andria C.; French, D. A; Gutierrez, Joseph V; Sanchez, Richard L; Slater, Timothy F.; Tatge, Coty

2014-06-01

Interactive lecture demonstrations (ILDs) have repeatedly shown to be effective tools for improving student achievement in the context of learning physics. As a first step toward systematic development of interactive lecture demonstrations in ASTRO 101, the introductory astronomy survey course, a systematic review of education research, describing educational computer simulations (ECSs) reveals that initial development requires a targeted study of how ASTRO 101 students respond to ECSs in the non-science majoring undergraduate lecture setting. In this project we have adopted the process by which ILDs were designed, pilot-tested, and successfully implemented in the context of physics teaching (Sokoloff & Thornton, 1997; Sokoloff & Thornton, 2004). We have designed the initial pilot-test set of ASTRO 101 ILD instructional materials relying heavily on ECSs. Both an instructor’s manual and a preliminary classroom-ready student workbook have been developed, and we are implementing a pilot study to explore their effectiveness in communicating scientific content, and the extent to which they might enhance students’ knowledge of and perception about astronomy and science in general. The study design uses a pre-/post-test quasi-experimental study design measuring students’ normalized gain scores, calculated as per Hake (1998) and Prather (2009), using a slightly modified version of S. Slater’s (2011) Test Of Astronomy STandards TOAST combined with other instruments. The results of this initial study will guide the iterative development of ASTRO 101 ILDs that are intended to both be effective at enhancing student achievement and easy for instructors to successfully implement.

Gregory, Kevin B; Winn, William; Johnson, Kent; Rosekind, Mark R

2010-01-01

Humans confront significant physiological challenges with sleep and alertness when working in 24/7 operations. A web-based national survey of air medical pilots examined issues relevant to fatigue and sleep management. Six hundred ninety-seven responses were received, with a majority of rotor wing pilots working 3/3/7 and 7/7 duty schedules. Over 84% of the pilots reported that fatigue had affected their flight performance; less than 28% reported "nodding off" during flight. More than 90% reported a separate work site "rest" room with a bed available. Over 90% reported no company policies restricting on-duty sleep. Approximately half of the pilots reported getting 4 hours or more sleep during a typical night shift. Approximately half reported that sleep inertia had never compromised flight safety. Over 90% reported that it was better to sleep during the night and overcome sleep inertia if necessary. Survey results reflected practices that can mitigate the degrading effects of fatigue, including the availability of designated work-site sleep rooms. As demands continue to evolve, the need remains for sustained efforts to address fatigue-related risks in the air medical transport industry. This includes further study of sleep inertia issues and the need for alertness management programs. Copyright © 2010 Air Medical Journal Associates. Published by Elsevier Inc. All rights reserved.

Views of Academic and Community Partners Regarding Participant Protections and Research Integrity: A Pilot Focus Group Study

PubMed Central

Anderson, Emily E.

2013-01-01

When community partners have direct interaction with human research participants, it is important to consider potential threats to participant protections and research integrity. Few studies have directly compared the views of academic and community partners. This pilot focus group study explores the views of academic partners (APs) and community partners (CPs) regarding challenges to the protection of research participants and research integrity in community-engaged research (CEnR). Data are analyzed to understand how APs and CPs define and think about ethical problems and how meaning and analysis may differ between the two groups. Findings have implications for the development of research ethics training materials for academic-community research partnerships and IRBs; best practices for CEnR; and future research on ethical issues in CEnR.

Low-dose aspirin in polycythaemia vera: a pilot study. Gruppo Italiano Studio Policitemia (GISP).

PubMed

1997-05-01

In this pilot study, aimed at exploring the feasibility of a large-scale trial of low-dose aspirin in polycythaemia vera (PV), 112 PV patients (42 females, 70 males. aged 17-80 years) were selected for not having a clear indication for, or contraindication to, aspirin treatment and randomized to receive oral aspirin (40 mg/d) or placebo. Follow-up duration was 16 +/- 6 months. Measurements of thromboxane A2 production during whole blood clotting demonstrated complete inhibition of platelet cyclooxygenase activity in patients receiving aspirin. Aspirin administration was not associated with any bleeding complication. Within the limitations of the small sample size, this study indicates that a biochemically effective regimen of antiplatelet therapy is well tolerated in patients with polycythaemia vera and that a large-scale placebo-controlled trial is feasible.

Methods for Discerning Cloud Reflectivity Changes due to the Indirect Effect of Aerosol: A Pilot-study for Triana

NASA Technical Reports Server (NTRS)

Kinne, S.; Wiscombe, Warren; Einaudi, Franco (Technical Monitor)

2001-01-01

Understanding the effect of aerosol on cloud systems is one of the major challenges in atmospheric and climate research. Local studies suggest a multitude of influences on cloud properties. Yet the overall effect on cloud albedo, a critical parameter in climate simulations, remains uncertain. NASA's Triana mission will provide, from its EPIC multi-spectral imager, simultaneous data on aerosol properties and cloud reflectivity. With Triana's unique position in space these data will be available not only globally but also over the entire daytime, well suited to accommodate the often short lifetimes of aerosol and investigations around diurnal cycles. This pilot study explores the ability to detect relationships between aerosol properties and cloud reflectivity with sophisticated statistical methods. Sample results using data from the EOS Terra platform to simulate Triana are presented.

2004-02-01

The relevance of resilience research for clinical practice has not yet been established. In this intervention pilot study, the aim was to explore how group work based on enhancing the participants' creativity, self-efficacy, active coping, and sense of continuity could be utilized within a clinical context for adolescents with stressful background experiences. 31 participants and 24 parents completed pre-, post-, and 1-yr. follow-up assessments of the youths' behavior difficulties, as well as depression, positive life attitude, coping, and prosocial behavior. Apart from a drop in self-rated prosocial behavior, no significant treatment effects were found. Implications for clinical practice and research are indicated.

Aviation System Safety and Pilot Risk Perception: Implications for Enhancing Decision-Making Skills

NASA Technical Reports Server (NTRS)

Green, Mavis F.

2001-01-01

This research explores risk perception in a defined population of flight instructors and the implications of these views for flight training. Flight instructors and students engaged in collegiate aviation flight training were interviewed for this qualitative study. Thirty-three percent of the instructors interviewed reported that flying is not a risky activity. This is important because research identifies risk perception as one factor influencing instructional choices. These choices can then impact the subsequent decision-making processes of flight students. Facilitating pilot decision-making through the use of an appropriate type of learning that incorporates the modeling of consensually validated cognitive procedures and risk management processes is discussed.

Enabling HST UV Exploration of the Low Surface Brightness Universe: A Pilot Study with the WFC3 X Filter Set

NASA Astrophysics Data System (ADS)

Thilker, David

2017-08-01

We request 17 orbits to conduct a pilot study to examine the effectiveness of the WFC3/UVIS F300X filter for studying fundamental problems in star formation in the low density regime. In principle, the broader bandpass and higher throughput of F300X can halve the required observing time relative to F275W, the filter of choice for studying young stellar populations in nearby galaxies. Together with F475W and F600LP, this X filter set may be as effective as standard UVIS broadband filters for characterizing the physical properties of such populations. We will observe 5 low surface brightness targets with a range of properties to test potential issues with F300X: the red tail to 4000A and a red leak beyond, ghosts, and the wider bandpass. Masses and ages of massive stars, young star clusters, and clumps derived from photometry from the X filter set will be compared with corresponding measurements from standard filters. Beyond testing, our program will provide the first sample spanning a range of LSB galaxy properties for which HST UV imaging will be obtained, and a glimpse into the ensemble properties of the quanta of star formation in these strange environments. The increased observing efficiency would make more tractable programs which require several tens to hundreds of orbits to aggregate sufficient numbers of massive stars, young star clusters, and clumps to build statistical samples. We are hopeful that our pilot observations will broadly enable high-resolution UV imaging exploration of the low density frontier of star formation while HST is still in good health.

2011-01-01

Brain Hyperscanning, i.e. the simultaneous recording of the cerebral activity of different human subjects involved in interaction tasks, is a very recent field of Neuroscience aiming at understanding the cerebral processes generating and generated by social interactions. This approach allows the observation and modeling of the neural signature specifically dependent on the interaction between subjects, and, even more interestingly, of the functional links existing between the activities in the brains of the subjects interacting together. In this EEG hyperscanning study we explored the functional hyperconnectivity between the activity in different scalp sites of couples of Civil Aviation Pilots during different phases of a flight reproduced in a flight simulator. Results shown a dense network of connections between the two brains in the takeoff and landing phases, when the cooperation between them is maximal, in contrast with phases during which the activity of the two pilots was independent, when no or quite few links were shown. These results confirms that the study of the brain connectivity between the activity simultaneously acquired in human brains during interaction tasks can provide important information about the neural basis of the "spirit of the group".

This pilot study tested the feasibility and impact of using mobile media devices to present peer health messages to human immunodeficiency virus (HIV)-positive patients. A convenience sample of 30 adult patients from an outpatient HIV clinic serving a mostly rural catchment area in central Virginia volunteered for the study. Participants viewed short videos of people discussing HIV health topics on an Apple (Cupertino, CA) iPod® touch® mobile device. Pre- and post-intervention surveys assessed attitudes related to engagement in care and disease disclosure. Participants found delivery of health information by the mobile device acceptable in a clinic setting. They used the technology without difficulty. Participants reported satisfaction with and future interest in viewing such videos after using the mobile devices. The majority of participants used the device to access more videos than requested, and many reported the videos "hit home." There were no significant changes in participant perceptions about engagement in care or HIV disclosure after the intervention. This pilot study demonstrates the feasibility and acceptability of using mobile media technology to deliver peer health messages. Future research should explore how to best use mobile media to improve engagement in care and reduce perceptions of stigma.

We have recently completed a pilot study on the Space shuttle wiring system commissioned by the Wiring Integrity Research (WIRe) team at NASA Ames Research Center, As the space shuttle ages, it is experiencing wiring degradation problems including arcing, chaffing insulation breakdown and broken conductors. A systematic and comprehensive test process is required to thoroughly test and quality assure (QA) the wiring systems. The NASA WIRe team recognized the value of a formal model based analysis for risk-assessment and fault coverage analysis. However. wiring systems are complex and involve over 50,000 wire segments. Therefore, NASA commissioned this pilot study with Qualtech Systems. Inc. (QSI) to explore means of automatically extracting high fidelity multi-signal models from wiring information database for use with QSI's Testability Engineering and Maintenance System (TEAMS) tool.

A Pilot Study of Deaf Trauma Survivors’ Experiences: Early Traumas Unique to Being Deaf in a Hearing World

Wolf Craig, Kelly S.; Hall, Wyatte C.; Ziedonis, Douglas M.

2016-01-01

Conducting semi-structured American Sign Language interviews with 17 Deaf trauma survivors, this pilot study explored Deaf individuals’ trauma experiences and whether these experiences generally align with trauma in the hearing population. Most commonly reported traumas were physical assault, sudden unexpected deaths, and “other” very stressful events. Although some “other” events overlap with traumas in the general population, many are unique to Deaf people (e.g., corporal punishment at oral/aural school if caught using sign language, utter lack of communication with hearing parents). These findings suggest that Deaf individuals may experience developmental traumas distinct to being raised in a hearing world. Such traumas are not captured by available trauma assessments, nor are they considered in evidence-based trauma treatments. PMID:28138351

A simulator study on information requirements for precision hovering

Lemons, J. L.; Dukes, T. A.

1975-01-01

A fixed base simulator study of an advanced helicopter instrument display utilizing translational acceleration, velocity and position information is reported. The simulation involved piloting a heavy helicopter using the Integrated Trajectory Error Display (ITED) in a precision hover task. The test series explored two basic areas. The effect on hover accuracy of adding acceleration information was of primary concern. Also of interest was the operators' ability to use degraded information derived from less sophisticated sources. The addition of translational acceleration to a display containing velocity and position information did not appear to improve the hover performance significantly. However, displayed acceleration information seemed to increase the damping of the man machine system. Finally, the pilots could use translational information synthesized from attitude and angular acceleration as effectively as perfect acceleration.

2016-01-01

The purpose of this pilot study was to explore whether individualized Reiki given to cancer patients at a Brazilian hospital improved symptoms and well-being. Data from 36 patients who received 5 Reiki sessions were collected using the MYMOP and were compared before and after their treatment and also with 14 patients who did not receive Reiki and who acted as a comparison group. Twenty-one patients reported feeling better, 12 felt worse, and 3 reported no change. Of the comparison group, 6 patients reported feeling better and 8 felt worse. The Reiki practice delivered as part of the integrative care in oncology did produce clinically significant effects, although not statistically significant results, for more than half of the patients undergoing cancer treatment.

Terminal Area Procedures for Paired Runways

NASA Technical Reports Server (NTRS)

Lozito, Sandra; Verma, Savita Arora

2011-01-01

Parallel runway operations have been found to increase capacity within the National Airspace but poor visibility conditions reduce the use of these operations. The NextGen and SESAR Programs have identified the capacity benefits from increased use of closely-space parallel runway. Previous research examined the concepts and procedures related to parallel runways however, there has been no investigation of the procedures associated with the strategic and tactical pairing of aircraft for these operations. This simulation study developed and examined the pilot and controller procedures and information requirements for creating aircraft pairs for parallel runway operations. The goal was to achieve aircraft pairing with a temporal separation of 15s (+/- 10s error) at a coupling point that was about 12 nmi from the runway threshold. Two variables were explored for the pilot participants: two levels of flight deck automation (current-day flight deck automation and auto speed control future automation) as well as two flight deck displays that assisted in pilot conformance monitoring. The controllers were also provided with automation to help create and maintain aircraft pairs. Results show the operations in this study were acceptable and safe. Subjective workload, when using the pairing procedures and tools, was generally low for both controllers and pilots, and situation awareness was typically moderate to high. Pilot workload was influenced by display type and automation condition. Further research on pairing and off-nominal conditions is required however, this investigation identified promising findings about the feasibility of closely-spaced parallel runway operations.

Exploration of an oculometer-based model of pilot workload

NASA Technical Reports Server (NTRS)

Krebs, M. J.; Wingert, J. W.; Cunningham, T.

1977-01-01

Potential relationships between eye behavior and pilot workload are discussed. A Honeywell Mark IIA oculometer was used to obtain the eye data in a fixed base transport aircraft simulation facility. The data were analyzed to determine those parameters of eye behavior which were related to changes in level of task difficulty of the simulated manual approach and landing on instruments. A number of trends and relationships between eye variables and pilot ratings were found. A preliminary equation was written based on the results of a stepwise linear regression. High variability in time spent on various instruments was related to differences in scanning strategy among pilots. A more detailed analysis of individual runs by individual pilots was performed to investigate the source of this variability more closely. Results indicated a high degree of intra-pilot variability in instrument scanning. No consistent workload related trends were found. Pupil diameter which had demonstrated a strong relationship to task difficulty was extensively re-exmained.

Massage therapy in post-operative rehabilitation of children and adolescents with cerebral palsy - a pilot study.

PubMed

Nilsson, Stefan; Johansson, Gunilla; Enskär, Karin; Himmelmann, Kate

2011-08-01

The purpose of this pilot study was to explore the use of massage therapy in children with cerebral palsy undergoing post-operative rehabilitation. Three participants were randomized to massage therapy and another three participants to rest. All children had undergone surgery in one or two lower limbs. Pain, wellbeing, sleep quality, heart rate and qualitative data were collected for each child. The scores of pain intensity and discomfort were low in all participants. Heart rate decreased in participants who were randomized to rest, but no change was found in the massage therapy group. The lack of decrease in heart rate in the study group of massage therapy may imply an increased sensitivity to touch in the post-operative setting. Further research with larger study populations are needed to evaluate how and when massage therapy is useful for children with cerebral palsy. Copyright © 2010 Elsevier Ltd. All rights reserved.

Can alginate-based preloads increase weight loss beyond calorie restriction? A pilot study in obese individuals.

PubMed

Georg Jensen, M; Kristensen, M; Astrup, A

2011-12-01

This randomized, controlled, 2-week intervention study in 24 obese subjects tested the effect on body weight loss and gastrointestinal tolerance of consuming low viscous alginate fibre-based preloads of 3% concentration (500 ml volume) three times a day as an adjuvant to a calorie-restricted diet. The pilot study showed that intake of the alginate preloads was moderately acceptable to the majority of subjects but did not produce additional body weight loss beyond calorie restriction (-1.42 ± 0.38 kg) (n=12) compared to control group (-1.56 ± 0.21 kg) (n=8). These results do not support that alginate supplementation enhance the weight loss effects of a hypo-caloric diet, but a sufficiently powered long-term study is needed to explore whether alginate could be an aid for improving weight loss during caloric-restriction.

Space transfer vehicle concepts and requirements study. Volume 1: Executive summary

NASA Technical Reports Server (NTRS)

Weber, Gary A.

1991-01-01

A description of the study in terms of background, objectives, and issues is provided. NASA is currently studying new initiatives of space exploration involving both piloted and unpiloted missions to destinations throughout the solar system. Many of these missions require substantial improvements in launch vehicle and upper stage capabilities. This study provides a focused examination of the Space Transfer Vehicles (STV) required to perform these missions using the emerging national launch vehicle definition, the Space Station Freedom (SSF) definition, and the latest mission scenario requirements. The study objectives are to define preferred STV concepts capable of accommodating future exploration missions in a cost-effective manner, determine the technology development (if any) required to perform these missions, and develop a decision database of various programmatic approaches for the development of the STV family of vehicles. Special emphasis was given to examining space basing (stationing reusable vehicles at a space station), examining the piloted lunar mission as a primary design mission, and restricting trade studies to the high-performance, near-term cryogenics (LO2/LH2) as vehicle propellant. The study progressed through three distinct 6-month phases. The first phase concentrated on supporting a NASA 3 month definition of exploration requirements (the '90-day study') and during this phase developed and optimized the space-based point-of-departure (POD) 2.5-stage lunar vehicle. The second phase developed a broad decision database of 95 different vehicle options and transportation architectures. The final phase chose the three most cost-effective architectures and developed point designs to carry to the end of the study. These reference vehicle designs are mutually exclusive and correspond to different national choices about launch vehicles and in-space reusability. There is, however, potential for evolution between concepts.

There is limited research exploring the pain experience of boys and young men with Duchenne Muscular Dystrophy. We conducted a mixed-methods pilot study to assess the feasibility of using particular measures of pain, pain coping and quality of life within semi-structured interviews with boys and young men with Duchenne Muscular Dystrophy and a postal survey of their parents. Non-probability, convenience sampling was used. Twelve young men aged 11-21 years (median 15 years), three of whom were still ambulant, and their parents/guardians were recruited. The measures used were acceptable to the young men and demonstrated potential to provide useful data. Two-thirds of young men suffered from significant daily pain which was associated with reduced quality of life. Pain complaints were largely kept within the family. Young men's pain-coping strategies were limited by their restricted physical abilities. Statistical power based on these preliminary results suggests a study of approximately 50 boys/young men which appears feasible. Further study is needed to explore acceptable and effective methods of pain management in this population and ways of enhancing pain-coping strategies. In clinical practice, assessment of pains and discomfort should form part of all routine consultations. Copyright © 2016 The Authors. Published by Elsevier Ltd.. All rights reserved.

For the first 5 years of the UK primary care pay for performance scheme, the Quality and Outcomes Framework (QOF), quality indicators were introduced without piloting. However, in 2009, potential new indicators were piloted in a nationally representative sample of practices. This paper describes an in-depth exploration of family physician, nurse and other primary-care practice staff views of the value of piloting with a particular focus on unintended consequences of 13 potential new QOF indicators. Fifty-seven family-practice professionals were interviewed in 24 representative practices across England. Almost all interviewees emphasised the value of piloting in terms of an opportunity to identify unintended consequences of potential QOF indicators in 'real world' settings with staff who deliver day-to-day care to patients. Four particular types of unintended consequences were identified: measure fixation, tunnel vision, misinterpretation and potential gaming. 'Measure fixation,' an inappropriate attention on isolated aspects of care, appeared to be the key unintended consequence. In particular, if the palliative care indicator had been introduced without piloting, this might have incentivised poorer care in a minority of practices with potential harm to vulnerable patients. It is important to identify concerns and experiences about unintended consequences of indicators at an early stage when there is time to remove or adapt problem indicators. Since the UK government currently spends over £1 billion each year on QOF, the £150,000 spent on each piloting cohort (0.0005% of the total QOF budget) appears to be good value for money.

Pilot Preferences on Displayed Aircraft Control Variables

Trujillo, Anna C.; Gregory, Irene M.

The experiments described here explored how pilots want available maneuver authority information transmitted and how this information affects pilots before and after an aircraft failure. The aircraft dynamic variables relative to flight performance were narrowed to energy management variables. A survey was conducted to determine what these variables should be. Survey results indicated that bank angle, vertical velocity, and airspeed were the preferred variables. Based on this, two displays were designed to inform the pilot of available maneuver envelope expressed as bank angle, vertical velocity, and airspeed. These displays were used in an experiment involving control surface failures. Results indicate the displayed limitations in bank angle, vertical velocity, and airspeed were helpful to the pilots during aircraft surface failures. However, the additional information did lead to a slight increase in workload, a small decrease in perceived aircraft flying qualities, and no effect on aircraft situation awareness.

A human-in-the-loop experiment was performed at the NASA Langley Research Center to study the feasibility of DAG-TM autonomous aircraft operations in highly constrained airspace. The airspace was constrained by a pair of special-use airspace (SUA) regions on either side of the pilot's planned route. Traffic flow management (TFM) constraints were imposed as a required time of arrival and crossing altitude at an en route fix. Key guidelines from the RTCA Airborne Conflict Management (ACM) concept were applied to autonomous aircraft operations for this experiment. These concepts included the RTCA ACM definitions of distinct conflict detection and collision avoidance zones, and the use of a graded system of conflict alerts for the flight crew. Three studies were conducted in the course of the experiment. The first study investigated the effect of hazard proximity upon pilot ability to meet constraints and solve conflict situations. The second study investigated pilot use of the airborne tools when faced with an unexpected loss of separation (LOS). The third study explored pilot interactions in an over-constrained conflict situation, with and without priority rules dictating who should move first. Detailed results from these studies were presented at the 5th USA/Europe Air Traffic Management R&D Seminar (ATM2003). This overview paper focuses on the integration of the RTCA ACM concept into autonomous aircraft operations in highly constrained situations, and provides an overview of the results presented at the ATM2003 seminar. These results, together with previously reported studies, continue to support the feasibility of autonomous aircraft operations.

To explore the feasibility of a workplace farmstand programme through the utilization of an online ordering system to build awareness for local food systems, encourage community participation, and increase local fruit and vegetable availability. A 4-week pilot to explore feasibility of workplace farmstand programmes through a variety of outcome measures, including survey, mode of sale, weekly sales totals and intercept interviews. A large private company in Sarpy County, Omaha, Nebraska, USA. Employees of the company hosting the farmstand programme. Pre-programme, a majority of employees indicated that quality (95·4 %), variety (94·6 %) and cost of fruits and vegetables (86·4 %) were driving factors in their fruit and vegetable selection when shopping. The availability of locally or regionally produced fruits and vegetables was highly important (78·1 %). Participants varied in their definition of local food, with nearly half (49·2 %) reporting within 80·5 km (50 miles), followed by 160·9 km (100 miles; 29·5 %) and 321·9 km (200 miles; 12·1 %). Weekly farmstand purchases (both walk-ups and online orders) ranged from twenty-eight to thirty-nine employees, with weekly sales ranging from $US 257·95 to 436·90 for the producer. The mode of purchase changed throughout the pilot, with higher use of online ordering in the beginning and higher use of walk-up purchasing at the end. The workplace farmstand pilot study revealed initial interest by both employees and a producer in this type of programme, helped to establish a sustained producer-employer relationship and led to additional opportunities for both the producer and employer.

Moral case deliberation (MCD) as a form of clinical ethics support is usually implemented in health care institutions and educational programs. While there is no previous research on the use of clinical ethics support on the level of health care regulation, employees of regulatory bodies are regularly confronted with moral challenges. This pilot study describes and evaluates the use of MCD at the Dutch Health Care Inspectorate (IGZ). The objective of this pilot study is to investigate: 1) the current way of dealing with moral issues at the IGZ; 2) experience with and evaluation of MCD as clinical ethics support, and 3) future preferences and (perceived) needs regarding clinical ethics support for dealing with moral questions at the IGZ. We performed an explorative pilot study. The research questions were assessed by means of: 1) interviews with MCD participants during four focus groups; and 2) interviews with six key stakeholders at the IGZ. De qualitative data is illustrated by data from questionnaires on MCD outcomes, perspective taking and MCD evaluation. Professionals do not always recognize moral issues. Employees report a need for regular and structured moral support in health care regulation. The MCD meetings are evaluated positively. The most important outcomes of MCD are feeling secure and learning from others. Additional support is needed to successfully implement MCD at the Inspectorate. We conclude that the respondents perceive moral case deliberation as a useful form of clinical ethics support for dealing with moral questions and issues in health care regulation.

Gasoline compression ignition concepts with the majority of the fuel being introduced early in the cycle are known as partially premixed combustion (PPC). Previous research on single- and multi-cylinder engines has shown that PPC has the potential for high thermal efficiency with low NOx and soot emissions. A variety of fuel injection strategies has been proposed in the literature. These injection strategies aim to create a partially stratified charge to simultaneously reduce NOx and soot emissions while maintaining some level of control over the combustion process through the fuel delivery system. The impact of the direct injection strategy to createmore » a premixed charge of fuel and air has not previously been explored, and its impact on engine efficiency and emissions is not well understood. This paper explores the effect of sweeping the direct injected pilot timing from -91° to -324° ATDC, which is just after the exhaust valve closes for the engine used in this study. During the sweep, the pilot injection consistently contained 65% of the total fuel (based on command duration ratio), and the main injection timing was adjusted slightly to maintain combustion phasing near top dead center. A modern four cylinder, 1.9 L diesel engine with a variable geometry turbocharger, high pressure common rail injection system, wide included angle injectors, and variable swirl actuation was used in this study. The pistons were modified to an open bowl configuration suitable for highly premixed combustion modes. The stock diesel injection system was unmodified, and the gasoline fuel was doped with a lubricity additive to protect the high pressure fuel pump and the injectors. The study was conducted at a fixed speed/load condition of 2000 rpm and 4.0 bar brake mean effective pressure (BMEP). The pilot injection timing sweep was conducted at different intake manifold pressures, swirl levels, and fuel injection GTP-15-1067, Dempsey 2 pressures. The gasoline used in this study has relatively high fuel reactivity with a research octane number of 68. The results of this experimental campaign indicate that the highest brake thermal efficiency and lowest emissions are achieved simultaneously with the earliest pilot injection timings (i.e., during the intake stroke).« less

The major indication for antibiotic use in Danish pigs is treatment of intestinal diseases post weaning. Clinical decisions on antibiotic batch medication are often based on inspection of diarrhoeic pools on the pen floor. In some of these treated diarrhoea outbreaks, intestinal pathogens can only be demonstrated in a small number of pigs within the treated group (low pathogen diarrhoea). Termination of antibiotic batch medication in herds suffering from such diarrhoea could potentially reduce the consumption of antibiotics in the pig industry. The objective of the present pilot study was to suggest criteria for herd diagnosis of low pathogen diarrhoea in growing pigs. Data previously collected from 20 Danish herds were used to create a case series of clinical diarrhoea outbreaks normally subjected to antibiotic treatment. In the present study, these diarrhoea outbreaks were classified as low pathogen (<15% of the pigs having bacterial intestinal disease) (n =5 outbreaks) or high pathogen (≥15% of the pigs having bacterial intestinal disease) (n =15 outbreaks). Based on the case series, different diagnostic procedures were explored, and criteria for herd diagnosis of low pathogen diarrhoea were suggested. The effect of sampling variation was explored by simulation. The diagnostic procedure with the highest combined herd-level sensitivity and specificity was qPCR testing of a pooled sample containing 20 randomly selected faecal samples. The criteria for a positive test result (high pathogen diarrhoea outbreak) were an average of 1.5 diarrhoeic faecal pools on the floor of each pen in the room under investigation and a pathogenic bacterial load ≥35,000 per gram in the faecal pool tested by qPCR. The bacterial load was the sum of Lawsonia intracellularis, Brachyspira pilosicoli and Escherichia coli F4 and F18 bacteria per gram faeces. The herd-diagnostic performance was (herd-level) diagnostic sensitivity =0.99, diagnostic specificity =0.80, positive predictive value =0.94 and negative predictive value =0.96. The pilot study suggests criteria for herd diagnosis of low pathogen diarrhoea in growing pigs. The suggested criteria should now be evaluated, and the effect of terminating antibiotic batch medication in herds identified as suffering from low pathogen diarrhoea should be explored.

Feedback to aid teachers in improving their teaching requires validated evaluation instruments. When implementing an evaluation instrument in a different context, it is important to collect validity evidence from multiple sources. We examined the validity and reliability of the Maastricht Clinical Teaching Questionnaire (MCTQ) as an instrument to evaluate individual clinical teachers during short clinical rotations in veterinary education. We examined four sources of validity evidence: (1) Content was examined based on theory of effective learning. (2) Response process was explored in a pilot study. (3) Internal structure was assessed by confirmatory factor analysis using 1086 student evaluations and reliability was examined utilizing generalizability analysis. (4) Relations with other relevant variables were examined by comparing factor scores with other outcomes. Content validity was supported by theory underlying the cognitive apprenticeship model on which the instrument is based. The pilot study resulted in an additional question about supervision time. A five-factor model showed a good fit with the data. Acceptable reliability was achievable with 10-12 questionnaires per teacher. Correlations between the factors and overall teacher judgement were strong. The MCTQ appears to be a valid and reliable instrument to evaluate clinical teachers' performance during short rotations.

To explore whether psychosocial challenges impact effects of vocational rehabilitation in Veterans with Posttraumatic Stress Disorder (PTSD). A post hoc exploratory analysis of possible moderators of treatment was conducted on outcomes from a randomized, controlled trial of Individual Placement and Support in Veterans with PTSD. When examining groups within each moderator, there was a greater IPS supportive employment benefit in gaining competitive employment for those with inadequate transportation (number needed to treat [NNT] = 1.5) and inadequate housing (NNT = 1.5) compared with the main finding of the pilot study (NNT = 2.07). Compared with the main finding of the pilot study, there was no greater advantage of IPS for those with adequate transportation (NNT = 2.4) or adequate housing (NNT = 2.4). Compared with the main finding in the pilot study, those without a family care burden had a greater benefit from IPS (NNT = 1.4) and those with family care burden had a reduced treatment effect (NNT = 3.3). These results are exploratory and are not intended to guide clinical decision-making, but rather offer a potentially useful strategy in the design of larger trials of IPS.

Feasibility Pilot Study: Training Soft Skills in Virtual Worlds.

Abshier, Patricia

2012-04-01

In a world where funding is limited, training for healthcare professionals is turning more and more to distance learning in an effort to maintain a knowledgeable and skilled work force. In 2010, Cicatelli Associates, Inc. began exploring the feasibility of using games and virtual worlds as an alternative means to teach skills-training in a distance-learning environment. The pilot study was conducted with six individuals familiar with general counseling and communication skills used by the healthcare industry to promote behavior change. Participants reported that the venue, although challenging at first, showed great potential for use with healthcare providers, as it allowed for more interaction and activities than traditional Webinars. However, there are significant limitations that must be overcome in order for this healthcare training modality to be utilized on a large scale. These limitations included a lack of microgestures and issues regarding the technology being used. In spite of the limitations, however, the potential use of virtual worlds for the training of healthcare providers exists and should be researched further. This article discusses the need and intended benefits of virtual world training as well as the results and conclusions of the pilot study.

In response to the Report of the Advisory Committee on the future of the U.S. Space Program and a request from NASA's Exploration Office, the MIT Hunsaker Aerospace Corporation (HAC) conducted a feasibility study, known as Project Columbiad, on reestablishing human presence on the Moon before the year 2000. The mission criteria established were to transport a four person crew to the lunar surface at any latitude and back to Earth with a 14-28 day stay on the lunar surface. Safety followed by cost of the Columbiad Mission were the top level priorities of HAC. The resulting design has a precursor mission that emplaces the required surface payloads before the piloted mission arrives. Both the precursor and piloted missions require two National Launch System (NLS) launches. Both the precursor and piloted missions have an Earth orbit rendezvous (EOR) with a direct transit to the Moon post-EOR. The piloted mission returns to Earth via a direct transit. Included among the surface payloads preemplaced are a habitat, solar power plant (including fuel cells for the lunar night), lunar rover, and mecanisms used to cover the habitat with regolith (lunar soil) in order to protect the crew members from severe solar flare radiation.

We sought to develop and pilot test a comprehensive health literacy communication training for various health professionals in Ireland, Italy and the Netherlands. Thirty health professionals participated in the study. A literature review focused on evidence-informed training-components. Focus group discussions (FGDs) explored perspectives from seventeen professionals on a prototype-program, and feedback from thirteen professionals following pilot-training. Pre-post questionnaires assessed self-rated health literacy communication skills. The literature review yielded five training-components to address functional, interactive and critical health literacy: health literacy education, gathering and providing information, shared decision-making, enabling self-management, and supporting behaviour change. In FGDs, professionals endorsed the prototype-program and reported that the pilot-training increased knowledge and patient-centred communication skills in addressing health literacy, as shown by self-rated pre-post questionnaires. A comprehensive training for health professionals in three European countries enhances perceived skills to address functional, interactive and critical health literacy. This training has potential for wider application in education and practice in Europe. Copyright © 2017 Elsevier B.V. All rights reserved.

Nighttime approaches to offshore installations in Brazil: Safety shortcomings experienced by helicopter pilots.

PubMed

Nascimento, Felipe A C; Majumdar, Arnab; Jarvis, Steve

2012-07-01

Accident rates for night sorties by helicopters traveling to offshore oil and gas platforms are at least five times higher than those during the daytime. Because pilots need to transition from automated flight to a manually flown night visual segment during arrival, the approach and landing phases cause great concern. Despite this, in Brazil, regulatory changes have been sought to allow for the execution of offshore night flights because of the rapid expansion of the petroleum industry. This study explores the factors that affect safety during night visual segments in Brazil using 28 semi-structured interviews with offshore helicopter pilots, followed by a template analysis of the narratives. The relationships among the factors suggest that flawed safety oversights, caused by a combination of lack of infrastructure for night flights offshore and declining training, currently favor spatial disorientation on the approach and near misses when close to the destination. Safety initiatives can be derived on the basis of these results. Copyright © 2012 Elsevier Ltd. All rights reserved.

PubMed

Kim, Eunhae; Gellis, Zvi D; Hoak, Vicki

2015-01-01

This pilot survey study explores current telehealth use among home health care agencies for chronic illness and depression care, and identifies factors associated with agencies' perception and intention to use telehealth. Between June and August 2014, 73 directors and 13 staff nurses (N = 86) from the Pennsylvania Homecare Association member agencies participated in an online survey. Eighty-five percent of telehealth provider agencies reported utilizing telehealth for monitoring health status while only 7.7% reported use for depression care. Telehealth technology was more positively perceived for chronic illness care (90.7%) than for depression care (53%) services. Factors associated with positive perceptions of telehealth were identified, including: (a) intention to use or continuing to use telehealth, (b) the size of the agency, (c) the participant's agency role, and (d) existence of depression services. These pilot findings have been used to inform the theoretical framework and the survey instrument for our U.S. national survey.

Understanding the determinants of problem-solving behavior in a complex environment

NASA Technical Reports Server (NTRS)

Casner, Stephen A.

1994-01-01

It is often argued that problem-solving behavior in a complex environment is determined as much by the features of the environment as by the goals of the problem solver. This article explores a technique to determine the extent to which measured features of a complex environment influence problem-solving behavior observed within that environment. In this study, the technique is used to determine how complex flight deck and air traffic control environment influences the strategies used by airline pilots when controlling the flight path of a modern jetliner. Data collected aboard 16 commercial flights are used to measure selected features of the task environment. A record of the pilots' problem-solving behavior is analyzed to determine to what extent behavior is adapted to the environmental features that were measured. The results suggest that the measured features of the environment account for as much as half of the variability in the pilots' problem-solving behavior and provide estimates on the probable effects of each environmental feature.

The influence of individualized music on patients in physical restraints: a pilot study.

PubMed

Janelli, Linda M; Kanski, Genevieve W; Wu, Yow-Wu Bill

This pilot study explored the relationship between listening to preferred music and the behavioral responses of patients who are physically restrained. Thirty patients, ranging in age from 65 to 93, participated in one of three groups. The first group included patients who were out of restraining devices while listening to preferred music. Patients in the second group were out of restraining devices and not exposed to music. The third group comprised patients who were in restraining devices while listening to preferred music. Listening to preferred music had no significant effect on decreasing patients' negative behaviors or on increasing positive behaviors observed during the intervention phase of the study. The higher mean scores for positive behaviors and lower mean scores for negative behaviors for the first group may indicate some benefits to patients who are out of restraints and listening to preferred music.

This article presents a systematic review of the literature pertaining to the use of yoga in stroke rehabilitation. In addition, we present the results of a small pilot study designed to explore the hypothesis that a Kundalini yoga practice of 12 weeks would lead to an improvement in aphasia as well as in fine motor coordination in stroke patients. The 3 participants attended yoga classes twice a week for 12 weeks, before and after which they were tested on the O'Connor Tweezer Dexterity test, a timed test where the participant places pins in a Peg-Board with tweezers, and the Boston Aphasia Exam for speech. All 3 participants showed improvement on both measures. The small sample size makes it impossible to draw definite conclusions, but the positive trends in this study suggest that further research should be done to examine the effects of Kundalini yoga on specific illnesses or medical conditions.

PubMed

Sanders, Lorraine B

2007-01-01

College students, often away from home for the first time, are at risk for mental health disorders that can affect academic performance and quality of life. The purpose of this pilot study was to describe the provision of mental health services to students attending colleges on Long Island, NY and to explore information about the policies developed in regards to disclosing mental health information to a student's family in the event of crisis. A descriptive questionnaire was developed for the purpose of this study. Qualified professionals are providing mental health services to students on Long Island college campuses but few policies exist to enhance communication in the event of crisis. Nurses employed in college health centers can work with students and families towards health-promoting behaviors and to proactively plan for the management of health information in the event of a mental health crisis.

Objective This pilot study explored psychosocial influences of e-cigarette use among dual users. Methods Two focus groups among adult current smokers who had ever used e-cigarettes were conducted in Georgia. Discussions were audio-recorded. Principles of grounded theory and thematic analysis were employed. Results Reasons for initial use included curiosity and social influence. Themes related to regular use included enjoyment of sensory experiences and perception of reduced harm. Nicotine craving, social image, and convenience were reasons for initial and regular dual use. Two patterns of use emerged – (1) using e-cigarettes to supplement combustible cigarettes; and (2) to replace combustible cigarettes. Conclusions Reasons for dual use were related to nicotine dependence, social influence, product appeal, and perception of reduced harm. Understanding contextual nuances of dual use can inform policy and communication. PMID:28393082

Stanton, L.; Cook, C. W.

1981-01-01

The multiple man machine interfaces inherent in military pilot training, their social implications, and the issue of possible negative feedback were explored. Modern technology has produced machines which can see, hear, and touch with greater accuracy and precision than human beings. Consequently, the military pilot is more a systems manager, often doing battle against a target he never sees. It is concluded that unquantifiable human activity requires motivation that is not intrinsic in a machine.

2015-01-01

"Emotional numbing" is a symptom of post-traumatic stress disorder (PTSD) characterized by a loss of interest in usually enjoyable activities, feeling detached from others, and an inability to express a full range of emotions. Emotional numbing is usually assessed through self-report, and is particularly difficult to ascertain among young children. We conducted a pilot study to explore the use of facial expression ratings in response to a comedy video clip to assess emotional reactivity among preschool children directly exposed to the Great East Japan Earthquake. This study included 23 child participants. Child PTSD symptoms were measured using a modified version of the Parent's Report of the Child's Reaction to Stress scale. Children were filmed while watching a 2-min video compilation of natural scenes ('baseline video') followed by a 2-min video clip from a television comedy ('comedy video'). Children's facial expressions were processed the using Noldus FaceReader software, which implements the Facial Action Coding System (FACS). We investigated the association between PTSD symptom scores and facial emotion reactivity using linear regression analysis. Children with higher PTSD symptom scores showed a significantly greater proportion of neutral facial expressions, controlling for sex, age, and baseline facial expression (p < 0.05). This pilot study suggests that facial emotion reactivity, measured using facial expression recognition software, has the potential to index emotional numbing in young children. This pilot study adds to the emerging literature on using experimental psychopathology methods to characterize children's reactions to disasters.

This pilot study aimed to explore whether criminal psychopaths can learn volitional regulation of the left anterior insula with real-time fMRI neurofeedback. Our previous studies with healthy volunteers showed that learned control of the blood oxygenation-level dependent (BOLD) signal was specific to the target region, and not a result of general arousal and global unspecific brain activation, and also that successful regulation modulates emotional responses, specifically to aversive picture stimuli but not neutral stimuli. In this pilot study, four criminal psychopaths were trained to regulate the anterior insula by employing negative emotional imageries taken from previous episodes in their lives, in conjunction with contingent feedback. Only one out of the four participants learned to increase the percent differential BOLD in the up-regulation condition across training runs. Subjects with higher Psychopathic Checklist-Revised (PCL:SV) scores were less able to increase the BOLD signal in the anterior insula than their lower PCL:SV counterparts. We investigated functional connectivity changes in the emotional network due to learned regulation of the successful participant, by employing multivariate Granger Causality Modeling (GCM). Learning to up-regulate the left anterior insula not only increased the number of connections (causal density) in the emotional network in the single successful participant but also increased the difference between the number of outgoing and incoming connections (causal flow) of the left insula. This pilot study shows modest potential for training psychopathic individuals to learn to control brain activity in the anterior insula. PMID:25352793

Mindfulness-based Intervention for Perinatal Grief Education and Reduction among Poor Women in Chhattisgarh, India: a Pilot Study.

PubMed

Roberts, Lisa; Montgomery, Susanne

2016-04-01

Stillbirth is a significant public health problem in low-to-middle-income countries and results in perinatal grief, often with negative psychosocial impact. In low-resource settings, such as Chhattisgarh, India, where needs are high, it is imperative to utilize low-cost, effective interventions. Mindfulness-based stress reduction (MBSR) is an empirically sound intervention that has been utilized for a broad range of physical and mental health problems, and is adaptable to specific populations. The main objective of this pilot study was to explore the feasibility and effectiveness of a shortened, culturally adapted mindfulness-based intervention to address complex grief after stillbirth. We used an observational, pre-post-6-week post study design. The study instrument was made up of descriptive demographic questions and validated scales and was administered as a structured interview due to low literacy rates. We used a community participatory approach to culturally adapt the five-week mindfulness-based intervention and delivered it through two trained local nurses. Quantitative and qualitative data analyses explored study outcomes as well as acceptability and feasibility of the intervention. 29 women with a history of stillbirth enrolled, completed the pretest and began the intervention; 26 completed the five-week intervention and post-test (89.7%), and 23 completed the six-week follow-up assessment (88.5%). Pretest results included elevated psychological symptoms and high levels of perinatal grief, including the active grief, difficulty coping, and despair subscales. General linear modeling repeated measures was used to explore posttest and six-week follow up changes from baseline, controlling for significantly correlated demographic variables. These longitudinal results included significant reduction in psychological symptoms; four of the five facets of mindfulness changed in the desired direction, two significantly; as well as significant reduction in overall perinatal grief and on each of the three subscales. The shortened, culturally adapted, mindfulness-based intervention pilot study was well received and had very low attrition. We also found significant reductions of perinatal grief and mental health symptoms over time, as well as a high degree of practice of mindfulness skills by participants. This study not only sheds light on the tremendous mental health needs among rural women of various castes who have experienced stillbirth in Chhattisgarh, it also points to a promising effective intervention with potential to be taken to scale for wider delivery.

In support of the NASA Aviation Safety Program's Synthetic Vision Systems Project, a series of piloted simulations were conducted to explore and quantify the relationship between candidate Terrain Portrayal Concepts and Guidance Symbology Concepts, specific to General Aviation. The experiment scenario was based on a low altitude en route flight in Instrument Metrological Conditions in the central mountains of Alaska. A total of 18 general aviation pilots, with three levels of pilot experience, evaluated a test matrix of four terrain portrayal concepts and six guidance symbology concepts. Quantitative measures included various pilot/aircraft performance data, flight technical errors and flight control inputs. The qualitative measures included pilot comments and pilot responses to the structured questionnaires such as perceived workload, subjective situation awareness, pilot preferences, and the rare event recognition. There were statistically significant effects found from guidance symbology concepts and terrain portrayal concepts but no significant interactions between them. Lower flight technical errors and increased situation awareness were achieved using Synthetic Vision Systems displays, as compared to the baseline Pitch/Roll Flight Director and Blue Sky Brown Ground combination. Overall, those guidance symbology concepts that have both path based guidance cue and tunnel display performed better than the other guidance concepts.

The development of a piloted flight simulator called the Ice Contamination Effects Flight Training Device (ICEFTD) was recently completed. This device demonstrates the ability to accurately represent an iced airplane s flight characteristics and is utilized to train pilots in recognizing and recovering from aircraft handling anomalies that result from airframe ice formations. The ICEFTD was demonstrated at three recent short courses hosted by the University of Tennessee Space Institute. It was also demonstrated to a group of pilots at the National Test Pilot School. In total, eighty-four pilots and flight test engineers from industry and the regulatory community spent approximately one hour each in the ICEFTD to get a "hands on" lesson of an iced airplane s reduced performance and handling qualities. Additionally, pilot cues of impending upsets and recovery techniques were demonstrated. The purpose of this training was to help pilots understand how ice contamination affects aircraft handling so they may apply that knowledge to the operations of other aircraft undergoing testing and development. Participant feedback on the ICEFTD was very positive. Pilots stated that the simulation was very valuable, applicable to their occupations, and provided a safe way to explore the flight envelope. Feedback collected at each demonstration was also helpful to define additional improvements to the ICEFTD; many of which were then implemented in subsequent demonstrations.

2000-01-01

Weather is one of the major causes of aviation accidents. General aviation (GA) flights account for 92% of all the aviation accidents, In spite of all the official and unofficial sources of weather visualization tools available to pilots, there is an urgent need for visualizing several weather related data tailored for general aviation pilots. Our system, Aviation Weather Data Visualization Environment AWE), presents graphical displays of meteorological observations, terminal area forecasts, and winds aloft forecasts onto a cartographic grid specific to the pilot's area of interest. Decisions regarding the graphical display and design are made based on careful consideration of user needs. Integral visual display of these elements of weather reports is designed for the use of GA pilots as a weather briefing and route selection tool. AWE provides linking of the weather information to the flight's path and schedule. The pilot can interact with the system to obtain aviation-specific weather for the entire area or for his specific route to explore what-if scenarios and make "go/no-go" decisions. The system, as evaluated by some pilots at NASA Ames Research Center, was found to be useful.

Objectives. Several groups in Manitoba, Canada, experience early childhood caries (ECC), including Aboriginal, immigrant, and refugee children and those from select rural regions. The purpose of this pilot study was to explore the views of parents and caregivers from four cultural groups on early childhood oral health and ECC. Methods. A qualitative descriptive study design using focus groups recruited parents and caregivers from four cultural groups. Discussions were documented, audio-recorded, transcribed, and then analyzed for content based on themes. Results. Parents and caregivers identified several potential barriers to good oral health practice, including child's temperament, finances, and inability to control sugar intake. Both religion and genetics were found to influence perceptions of oral health. Misconceptions regarding breastfeeding and bottle use were present. One-on-one discussions, parental networks, and using laypeople from similar backgrounds were suggested methods to promote oral health. The immigrant and refugee participants placed emphasis on the use of visuals for those with language barriers while Hutterite participants suggested a health-education approach. Conclusions. These pilot study findings provide initial insight into the oral health-related knowledge and beliefs of these groups. This will help to inform planning of ECC prevention and research strategies, which can be tailored to specific populations. PMID:24624141

This paper aims to contribute to the development of a more sustainable Australian rural community mental health workforce by comparing the findings from a literature search investigating impacting factors on retention with the experiences of community mental health service managers running services in rural Australia. Semi-structured interviews. Public health sector, rural New South Wales. Five community mental health managers, running services in rural Australia. Interviews were undertaken as a pilot for a broader qualitative study investigating factors influencing the decision to stay or leave among community mental health professionals working in rural positions. The purpose of undertaking this pilot study was to test for validity and relevance of the retention phenomena and help inform the research design for the main study. Three key retention focussed themes were identified: (i) Staffing is a persistent challenge; (ii) Small remote towns pose the biggest challenge; and (iii) The decision to stay or leave is complex and multifactorial. The findings of this pilot study support previous research and contribute to the understanding of influences on retention among health professionals working in rural community mental health services. Importantly, those who have worked for several years in rural positions hold important information through which to explore factors that impact retention in rural and remote regions. © 2015 National Rural Health Alliance Inc.

Metacognitive therapy (MCT) is one of the newer developments within cognitive therapy. This randomized controlled pilot study compared independently applied MCT with cognitive behavioural therapy (CBT) in outpatients with depression to explore the relative speed and efficacy of MCT, ahead of a planned randomized controlled trial. A total of 48 participants referred for outpatient therapy were randomized to up to 12 weeks of MCT or CBT. Key outcomes were reduction in depressive symptoms at week 4 and week 12, measured using the independent-clinician-rated Quick Inventory of Depressive Symptomatology16. Intention-to-treat and completer analyses as well as additional methods of reporting outcome of depression are presented. Both therapies were effective in producing clinically significant change in depressive symptoms, with moderate-to-large effect sizes obtained. No differences were detected between therapies in overall outcome or early change on clinician-rated or self-reported measures. Post-hoc analyses suggest that MCT may have been adversely affected by greater comorbidity. In this large pilot study conducted independently of MCT's developers, MCT was an effective treatment for outpatients with depression, with similar results overall to CBT. Insufficient power and imbalanced comorbidity limit conclusions regarding comparative efficacy so further studies of MCT and CBT are required. © The Royal Australian and New Zealand College of Psychiatrists 2014.

The relation between child feeding problems as measured by parental report and mealtime behavior observation: A pilot study.

van Dijk, Marijn; Bruinsma, Eke; Hauser, M Paulina

2016-04-01

Because feeding problems have clear negative consequences for both child and caretakers, early diagnosis and intervention are important. Parent-report questionnaires can contribute to early identification, because they are efficient and typically offer a 'holistic' perspective of the child's eating in different contexts. In this pilot study, we aim to explore the concurrent validity of a short screening instrument (the SEP, which is the Dutch MCH-FS) in one of its target populations (a group of premature children) by comparing the total score with the observed behavior of the child and caretaker during a regular home meal. 28 toddlers (aged 9-18 months) and their caretakers participated in the study. Video-observations of the meals were coded for categories of eating behavior and parent-child interaction. The results show that the total SEP-score correlates with food refusal, feeding efficiency, and self-feeding, but not with negative affect and parental instructions. This confirms that the SEP has a certain degree of concurrent validity in the sense that its total score is associated with specific 'benchmark' feeding behaviors: food refusal, feeding efficiency and autonomy. Future studies with larger samples are needed to generalize the findings from this pilot to a broader context. Copyright © 2016 Elsevier Ltd. All rights reserved.

Improved Lunar Lander Handling Qualities Through Control Response Type and Display Enhancements

NASA Technical Reports Server (NTRS)

Mueller, Eric Richard; Bilimoria, Karl D.; Frost, Chad Ritchie

2010-01-01

A piloted simulation that studied the handling qualities for a precision lunar landing task from final approach to touchdown is presented. A vehicle model based on NASA's Altair Lunar Lander was used to explore the design space around the nominal vehicle configuration to determine which combination of factors provides satisfactory pilot-vehicle performance and workload; details of the control and propulsion systems not available for that vehicle were derived from Apollo Lunar Module data. The experiment was conducted on a large motion base simulator. Eight Space Shuttle and Apollo pilot astronauts and three NASA test pilots served as evaluation pilots, providing Cooper-Harper ratings, Task Load Index ratings and qualitative comments. Each pilot flew seven combinations of control response types and three sets of displays, including two varieties of guidance and a nonguided approach. The response types included Rate Command with Attitude Hold, which was used in the original Apollo Moon landings, a Velocity Increment Command response type designed for up-and-away flight, three response types designed specifically for the vertical descent portion of the trajectory, and combinations of these. It was found that Velocity Increment Command significantly improved handling qualities when compared with the baseline Apollo design, receiving predominantly Level 1 ratings. This response type could be flown with or without explicit guidance cues, something that was very difficult with the baseline design, and resulted in approximately equivalent touchdown accuracies and propellant burn as the baseline response type. The response types designed to be used exclusively in the vertical descent portion of the trajectory did not improve handling qualities.

Eighteenth-century gardens have traditionally been viewed as spaces designed for leisure, and as representations of political status, power and taste. In contrast, this paper will explore the concept that gardens in this period could be seen as dynamic spaces where scientific experiment and medical practice could occur. Two examples have been explored in the pilot study which has led to this paper — the designed landscapes associated with John Hunter’s Earl’s Court residence, in London, and the garden at Edward Jenner’s house in Berkeley, Gloucestershire. Garden history methodologies have been implemented in order to consider the extent to which these domestic gardens can be viewed as experimental spaces. PMID:26052165

Spacecraft Design Considerations for Piloted Reentry and Landing

NASA Technical Reports Server (NTRS)

Stroud, Kenneth J.; Klaus, David M.

2006-01-01

With the end of the Space Shuttle era anticipated in this decade and the requirements for the Crew Exploration Vehicle (CEV) now being defined, an opportune window exists for incorporating 'lessons learned' from relevant aircraft and space flight experience into the early stages of designing the next generation of human spacecraft. This includes addressing not only the technological and overall mission challenges, but also taking into account the comprehensive effects that space flight has on the pilot, all of which must be balanced to ensure the safety of the crew. This manuscript presents a unique and timely overview of a multitude of competing, often unrelated, requirements and constraints governing spacecraft design that must be collectively considered in order to ensure the success of future space exploration missions.

Subcutaneous administration of fentanyl in childbirth: an observational study on the clinical effectiveness of fentanyl for mother and neonate.

PubMed

Fleet, Julie; Jones, Meril; Belan, Ingrid

2014-01-01

to explore the maternal and neonatal effects of fentanyl administered subcutaneously to women during labour. two methods were used: (1) A retrospective audit of the birth register and maternal and neonatal records for the period from January 2000 to December 2007. (2) A pilot study was also conducted on a convenience sample of women between July 2008 and October 2008. this study was conducted within a maternity unit at a rural South Australian hospital where approximately 350 babies are birthed each year. audit participants included women who had uncomplicated pregnancies and birthed at term (37-42 weeks gestation). Women in the experimental group consisted of those who had utilised only subcutaneous fentanyl for pain relief (n=75), or nitrous oxide and oxygen prior to being administered subcutaneous fentanyl (n=196). Stratified random selection based on parity and age was used to determine the control group, which consisted of women who used no pharmacological pain relief (n=196). The pilot study involved a convenience sample of women (n=10) assessed to have an uncomplicated pregnancy and labour occurring at term (≥37 weeks gestation). audit variables examined included the women's age, parity, labour duration, mode of birth (spontaneous or assisted), analgesia used, total dosage, time administered prior to birth, time of birth, neonatal Apgar scores, time to establish breathing, naloxone use, days spent in hospital post-birth and breast-feeding outcomes upon discharge. The pilot study explored maternal effects assessed pre- and 30 minutes post-administration of subcutaneously administered fentanyl by observing pain scores, vital signs, sedation levels, nausea/vomiting scores and anti-emetic use. To assess possible adverse effects in the neonate Apgar scores, time to establish respiration, naloxone use, transfer to neonatal nursery and breast-feeding outcomes upon discharge were recorded. women in the experimental groups were more likely to be induced, experienced a longer duration of labour and had an increased likelihood of an assisted vaginal birth. The average total dose of fentanyl administered was 250 μg. Neonatal outcomes were comparable between groups when examining Apgar scores <7 at 1 and 5 minutes and time to establish breathing. There was, however, a significant difference with naloxone administration between the groups. There was no significant difference between groups in hospital stay or breast-feeding on discharge. The pilot study identified a clinically significant reduction in pain scores for 78% of women following the administration of subcutaneous fentanyl, with the average pain score decreasing from 8.4 (±1.4) to 7.2 (±1.1) (paired t-test, p=0.017). Vital signs were not affected, no anti-emetics were required and all women remained alert with no sedation noted. the audit identified fentanyl use was associated with a longer length of labour, but this may be explained by more women in the experimental groups requiring induction of labour than those in the control group. However, length of hospital stay, breast-feeding rates and neonatal outcomes were comparable amongst the three groups. Results of the pilot study are consistent with those of the audit in relation to the effects on mother and neonate. In addition, the pilot study begins to provide evidence that fentanyl is efficacious in providing pain relief. results of this study are the first to explore the effects of fentanyl administered subcutaneously to women during labour. This method of analgesia offers women an additional choice of pain relief during childbirth and may be particularly beneficial in remote and rural settings where resources are often limited and access to specialist services difficult. Further research, however, is required to be able to generalise the outcomes and provide further data to support the clinical effectiveness of this route of administration of fentanyl.

2014-10-22

The single most distressing symptom for patients with advanced esophageal cancer is dysphagia. Amongst the more effective treatments for relief of dysphagia is insertion of a self-expanding metal stent (SEMS). It is possible that the addition of a palliative dose of external beam radiotherapy may prolong the relief of dysphagia and provide additional survival benefit. The ROCS trial will assess the effect of adding palliative radiotherapy after esophageal stent insertion. The study is a randomized multicenter phase III trial, with an internal pilot phase, comparing stent alone versus stent plus palliative radiotherapy in patients with incurable esophageal cancer. Eligible participants are those with advanced esophageal cancer who are in need of stent insertion for primary management of dysphagia. Radiotherapy will be administered as 20 Gray (Gy) in five fractions over one week or 30 Gy in 10 fractions over two weeks, within four weeks of stent insertion. The internal pilot will assess rates and methods of recruitment; pre-agreed criteria will determine progression to the main trial. In total, 496 patients will be randomized in a 1:1 ratio with follow up until death. The primary outcome is time to progression of patient-reported dysphagia. Secondary outcomes include survival, toxicity, health resource utilization, and quality of life. An embedded qualitative study will explore the feasibility of patient recruitment by examining patients' motivations for involvement and their experiences of consent and recruitment, including reasons for not consenting. It will also explore patients' experiences of each trial arm. The ROCS study will be a challenging trial studying palliation in patients with a poor prognosis. The internal pilot design will optimize methods for recruitment and data collection to ensure that the main trial is completed on time. As a pragmatic trial, study strengths include collection of all follow-up data in the usual place of care, and a focus on patient-reported, rather than disease-orientated, outcomes. Exploration of patient experience and health economic analyses will be integral to the assessment of benefit for patients and the NHS. The trial was registered with Current Controlled Trials (registration number: ISRCTN12376468) on 10 July 2012.

Sedentary behaviours have been linked to poor health, independent of physical activity levels. The objective of this study was to explore an individualised intervention strategy aimed at reducing sedentary behaviours in older Scottish adults. This feasibility and pilot study was a pre-experimental (one group pretest-posttest) study design. Participants were enrolled into the study in January-March 2012 and data analysis was completed April-October 2012. The study was based in Glasgow, Scotland. Participants received an individualised consultation targeting sedentary behaviour incorporating feedback from an activPAL activity monitor. Outcome measures were objectively (activPAL) and subjectively measured (Sedentary Behaviour Questionnaire) sedentary time. Twenty four participants received the intervention. Objectively measured total time spent sitting/lying was reduced by 24 min/day (p=0.042), a reduction of 2.2%. Total time spent in stepping activities, such as walking increased by 13 min/day (p=0.044). Self-report data suggested participants achieved behaviour change by reducing time spent watching television and/or using motorised transport. Interventions to reduce sedentary behaviours in older people are urgently needed. The results of this feasibility and pilot study suggest a consultation approach may help individuals reduce time spent in sedentary behaviours. A larger, controlled trial is warranted with a diverse sample to increase generalisability. © 2013.

Spirituality, Religiosity, and Weight Management Among African American Adolescent Males: The Jackson Heart KIDS Pilot Study.

Spirituality and religion have been identified as important determinants of health for adults; however, the impact of faith-oriented factors on health behaviors and outcomes among African American adolescent males has not been well studied. The purpose of this study is to examine the relationship between religiosity and spirituality and obesity-related behaviors among 12-19 year old African American males (N = 105) in the Jackson Heart KIDS Pilot Study. Key variables of interest are church attendance, prayer, daily spirituality, weight status, attempts to lose weight, nutrition, physical activity, and stress. Daily spirituality is associated with whether an individual attempts to lose weight. The results from logistic regression models suggest that daily spirituality increases the odds that African American male adolescents attempt to lose weight (OR = 1.22, CI: 1.07-1.41) and have a history of diet-focused weight management (OR = 1.13, CI: 1.02-1.26). Future studies are needed to further explore the association between religion, spirituality, and obesity-related behaviors.

Consequences of cognitive impairments following traumatic brain injury: Pilot study on visual exploration while driving.

The aim was to assess the visual exploration of a person suffering from traumatic brain injury (TBI). It was hypothesized that visual exploration could be modified as a result of attentional or executive function deficits that are often observed following brain injury. This study compared an analysis of eyes movements while driving with data from neuropsychological tests. Five participants suffering from TBI and six control participants took part in this study. All had good driving experience. They were invited to drive on a fixed-base driving simulator. Eye fixations were recorded using an eye tracker. Neuropsychological tests were used to assess attention, working memory, rapidity of information processing and executive functions. Participants with TBI showed a reduction in the variety of the visual zones explored and a reduction of the distance of exploration. Moreover, neuropsychological evaluation indicates that there were difficulties in terms of divided attention, anticipation and planning. There is a complementarity of the information obtained. Tests give information about cognitive deficiencies but not about their translation into a dynamic situation. Conversely, visual exploration provides information about the dynamic with which information is picked up in the environment but not about the cognitive processes involved.

The leap motion controller (LMC) is a new optoelectronic system for capturing motion of both hands and controlling a virtual environment. Differently from previous devices, it optoelectronically tracks the fine movements of fingers neither using glows nor markers. This pilot study explored the feasibility of adapting the LMC, developed for videogames, to neurorehabilitation of elderly with subacute stroke. Four elderly patients (71.50 ± 4.51 years old) affected by stroke in subacute phase were enrolled and tested in a cross-over pilot trial in which six sessions of 30 minutes of LMC videogame-based therapy were added on conventional therapy. Measurements involved participation to the sessions, evaluated by means of the Pittsburgh Rehabilitation Participation Scale, hand ability and grasp force evaluated respectively by means of the Abilhand Scale and by means of the dynamometer. Neither adverse effects nor spasticity increments were observed during LMC training. Participation to the sessions was excellent in three patients and very good in one patient during the LMC trial. In this period, patients showed a significantly higher improvement in hand abilities (P = 0.028) and grasp force (P = 0.006). This feasibility pilot study was the first one using leap motion controller for conducting a videogame-based therapy. This study provided a proof of concept that LMC can be a suitable tool even for elderly patients with subacute stroke. LMC training was in fact performed with a high level of active participation, without adverse effects, and contributed to increase the recovery of hand abilities.

Effect of chiropractic manipulation on vertical jump height in young female athletes with talocrural joint dysfunction: a single-blind randomized clinical pilot trial.

The main objective of this pilot study was to explore the effect of chiropractic high-velocity, low-amplitude (HVLA) manipulation on vertical jump height in young female athletes with talocrural joint dysfunction. This was a randomized assessor-blind clinical pilot trial. Twenty-two female handball players with talocrural joint dysfunction were randomized to receive either HVLA manipulation (n = 11) or sham treatment (n = 11) once a week during a 3-week period. The main outcome was change in vertical jump height from baseline to follow-up within and between groups after 3 weeks. Nineteen athletes completed the study. After 3 weeks, the group receiving HVLA manipulation (n = 11) had a statistically significant mean (SD) improvement in vertical jump height of 1.07 (1.23) cm (P = .017). The sham treatment group (n = 8) improved their vertical jump height by 0.59 (2.03) cm (P = .436). The between groups' change was 0.47 cm (95% confidence interval, -1.31 to 2.26; P = .571) in favor of the group receiving HVLA manipulation. Blinding and sham procedures were feasible, and there were no reported adverse events. The results of this pilot study show that a larger-scale study is feasible. Preliminary results suggest that chiropractic HVLA manipulation may increase vertical jump height in young female athletes with talocrural joint dysfunction. However, the clinical result in favor of HVLA manipulation compared with sham treatment needs statistical confirmation in a larger randomized clinical trial.

Prevalence of tricyclic antidepressants (TCAs) has not been explored in pilots. The National Transportation Safety Board (NTSB) aviation accident and the Federal Aviation Administration's Civil Aerospace Medical Institute (CAMI) toxicology and medical certification databases were searched for pilots fatally injured in aviation accidents. During 1990-2012, CAMI received bio-samples of pilots from 7037 aviation accidents. Of these, 2644 cases were positive for drugs. TCAs were present in 31. TCA blood concentrations ranged from therapeutic to toxic levels. The NTSB determined that the use of drugs and ethanol as the probable cause or contributing factor in 35% (11 of 31) of the accidents. None of the 31 pilots reported the use of TCAs during their aviation medical examination. The prevalence of TCAs in aviators was less than 0.5% (31 of 7037 cases). There is a need for aviators to fully disclose the use of medications at the time of their medical examination. © 2016 American Academy of Forensic Sciences.

This pilot study explored the link between predatory lending and health care debt among Hispanics. Research shows that links exist between health care costs, debt, poverty, and race ( Draught & Silva, 2003 ; Zeldin & Rukavina, 2007 ). Prior to this study there was no research on the intersection between medical debt and predatory lending although there was reason to believe this link exists ( Seifert, 2004 ). Our results confirm this link and we propose means to break it.

Adults with chronic kidney disease (CKD) exhibit alterations in tryptophan metabolism, mainly via the kynurenine pathway, due to higher enzymatic activity induced mainly by inflammation. Indoles produced by gut-microflora are another group of tryptophan metabolites related to inflammation and conditions accompanying CKD. Disruptions in tryptophan metabolism have been associated with various neurological and psychological disorders. A high proportion of CKD patients self-report symptoms of depression and/or anxiety and decline in cognitive functioning. This pilot study examines tryptophan metabolism in CKD and explores associations with psychological and cognitive functioning. Twenty-seven adults with CKD were part of 49 patients recruited to participate in a prospective pilot study, initially with an eGFR of 15-29 mL/min/1.73 m 2 . Only participants with viable blood samples and complete psychological/cognitive data at a 2-year follow-up were included in the reported cross-sectional study. Serum samples were analysed by Liquid Chromatography coupled to Mass Spectrometry, for tryptophan, ten of its metabolites, the inflammation marker neopterin and the hypothalamic-pituitary-adrenal (HPA) axis marker cortisol. The tryptophan breakdown index (kynurenine / tryptophan) correlated with neopterin (Pearson R = 0.51 P = 0.006) but not with cortisol. Neopterin levels also correlated with indoxyl sulfate (R = 0.68, P < 0.0001) and 5 metabolites of tryptophan (R range 0.5-0.7, all P ≤ 0.01), which were all negatively related to eGFR (P < 0.05). Higher levels of kynurenic acid were associated with lower cognitive functioning (Spearman R = -0.39, P < 0.05), while indole-3 acetic acid (IAA) was correlated with anxiety and depression (R = 0.52 and P = 0.005, R = 0.39 and P < 0.05, respectively). The results of this preliminary study suggest the involvement of inflammation in tryptophan breakdown via the kynurenine pathway, yet without sparing tryptophan metabolism through the 5-HT (serotonin) pathway in CKD patients. The multiple moderate associations between indole-3 acetic acid and psychological measures were a novel finding. The presented pilot data necessitate further exploration of these associations within a large prospective cohort to assess the broader significance of these findings.

Healing pathways: art therapy for American Indian cancer survivors.

Warson, Elizabeth

2012-04-01

There is a paucity of research addressing quality of life factors for American Indian and Alaska Native cancer survivors. Complementary forms of therapy, such as art therapy, are beginning to address quality of life factors through the "healing" arts for cancer survivors. The purpose of this mixed methods pilot was to explore the effects of culturally relevant art interventions on stress reduction for American Indian cancer survivors and their family members. Forty-six adult participants attended one of three workshops held within two settlements of the Coharie tribe and one southeastern urban tribal center. The data collected consisted of a pretest and posttest State-Trait Personality Inventory (STPI) and artwork resulting from three directed interventions. The artwork was analyzed using qualitative coding methods; however, the scores from the STPI were inconclusive because the inventory was determined to be culturally biased. While statistical significance was not achieved, the findings from qualitative coding reinforced a native concept of wellness focusing on the complex interaction between mind, body, spirit, and context. This pilot study also demonstrated how a community-driven approach was instrumental in the development of the overall workshop format. An expansion of the pilot study is also presented with preliminary results available in 2012.

Simulation debriefing based on principles of transfer of learning: A pilot study.

2017-09-01

Upon completion of undergraduate nursing courses, new graduates are expected to transition seamlessly into practice. Education providers face challenges in the preparation of undergraduate nurses due to increasing student numbers and decreasing availability of clinical placement sites. High fidelity patient simulation is an integral component of nursing curricula as an adjunct to preparation for clinical placement. Debriefing after simulation is an area where the underlying structure of problems can consciously be explored. When central principles of problems are identified, they can then be used in situations that differ from the simulation experience. Third year undergraduate nursing students participated in a pilot study conducted to test a debriefing intervention where the intervention group (n=7) participated in a simulation, followed by a debriefing based on transfer of learning principles. The control group (n=5) participated in a simulation of the same scenario, followed by a standard debriefing. Students then attended focus group interviews. The results of this pilot test provided preliminary information that the debriefing approach based on transfer of learning principles may be a useful way for student nurses to learn from a simulated experience and consider the application of learning to future clinical encounters.

This pilot study explores the metabolic changes associated with persistent postconcussion syndrome (PCS) after mild traumatic brain injury (mTBI; >12 months after injury) using magnetic resonance spectroscopy. We hypothesized that those mTBI participants with PCS will have larger metabolic differences than those without. Data were collected from mTBI participants with PCS, mTBI participants without PCS and non-head-injured participants (all groups: n=8). Magnetic resonance spectroscopy metabolite profiles within the dorsolateral prefrontal cortex showed a reduced creatine/choline ratio in mTBI patients compared with control participants. This data provides initial evidence for residual metabolic changes in chronic mTBI patients, but there was no conclusive relationship between these metabolic changes and PCS symptom report. Creatine is involved in maintaining energy levels in cells with high or fluctuating energy demand, suggesting that there may be some residual energy impairment in chronic mTBI.

The application of the pilot points in groundwater numerical inversion model

Numerical inversion simulation of groundwater has been widely applied in groundwater. Compared to traditional forward modeling, inversion model has more space to study. Zones and inversing modeling cell by cell are conventional methods. Pilot points is a method between them. The traditional inverse modeling method often uses software dividing the model into several zones with a few parameters needed to be inversed. However, distribution is usually too simple for modeler and result of simulation deviation. Inverse cell by cell will get the most actual parameter distribution in theory, but it need computational complexity greatly and quantity of survey data for geological statistical simulation areas. Compared to those methods, pilot points distribute a set of points throughout the different model domains for parameter estimation. Property values are assigned to model cells by Kriging to ensure geological units within the parameters of heterogeneity. It will reduce requirements of simulation area geological statistics and offset the gap between above methods. Pilot points can not only save calculation time, increase fitting degree, but also reduce instability of numerical model caused by numbers of parameters and other advantages. In this paper, we use pilot point in a field which structure formation heterogeneity and hydraulics parameter was unknown. We compare inversion modeling results of zones and pilot point methods. With the method of comparative analysis, we explore the characteristic of pilot point in groundwater inversion model. First, modeler generates an initial spatially correlated field given a geostatistical model by the description of the case site with the software named Groundwater Vistas 6. Defining Kriging to obtain the value of the field functions over the model domain on the basis of their values at measurement and pilot point locations (hydraulic conductivity), then we assign pilot points to the interpolated field which have been divided into 4 zones. And add range of disturbance values to inversion targets to calculate the value of hydraulic conductivity. Third, after inversion calculation (PEST), the interpolated field will minimize an objective function measuring the misfit between calculated and measured data. It's an optimization problem to find the optimum value of parameters. After the inversion modeling, the following major conclusion can be found out: (1) In a field structure formation is heterogeneity, the results of pilot point method is more real: better fitting result of parameters, more stable calculation of numerical simulation (stable residual distribution). Compared to zones, it is better of reflecting the heterogeneity of study field. (2) Pilot point method ensures that each parameter is sensitive and not entirely dependent on other parameters. Thus it guarantees the relative independence and authenticity of parameters evaluation results. However, it costs more time to calculate than zones.

The current day flight deck operational environment consists of a two-person Captain/First Officer crew. A concept of operations (ConOps) to reduce the commercial cockpit to a single pilot from the current two pilot crew is termed Single Pilot Operations (SPO). This concept has been under study by researchers in the Flight Deck Display Research Laboratory (FDDRL) at the National Aeronautics and Space Administration's (NASA) Ames (Johnson, Comerford, Lachter, Battiste, Feary, and Mogford, 2012) and researchers from Langley Research Centers (Schutte et al., 2007). Transitioning from a two pilot crew to a single pilot crew will undoubtedly require changes in operational procedures, crew coordination, use of automation, and in how the roles and responsibilities of the flight deck and ATC are conceptualized in order to maintain the high levels of safety expected of the US National Airspace System. These modifications will affect the roles and the subsequent tasks that are required of the various operators in the NextGen environment. The current report outlines the process taken to identify and document the tasks required by the crew according to a number of operational scenarios studied by the FDDRL between the years 2012-2014. A baseline task decomposition has been refined to represent the tasks consistent with a new set of entities, tasks, roles, and responsibilities being explored by the FDDRL as the move is made towards SPO. Information from Subject Matter Expert interviews, participation in FDDRL experimental design meetings, and study observation was used to populate and refine task sets that were developed as part of the SPO task analyses. The task analysis is based upon the proposed ConOps for the third FDDRL SPO study. This experiment possessed nine different entities operating in six scenarios using a variety of SPO-related automation and procedural activities required to guide safe and efficient aircraft operations. The task analysis presents the roles and responsibilities in a manner that can facilitate testing future scenarios. Measures of task count and workload were defined and analyzed to assess the impact of transitioning to a SPO environment.

In patients with COPD, psychological interventions usually target generalized anxiety and depression rather than the sensation of breathlessness. The objectives of this pilot study were to develop and implement a cognitive behavioral therapy (CBT) program specific to the perceptual experience of breathlessness, identify practical issues in the study protocol, and estimate beneficial effects of combining the CBT program with comprehensive pulmonary rehabilitation. The CBT program for the sensation of breathlessness (Breathing: Recognize sensations, Explore thoughts and beliefs, Validate thoughts as useful or harmful, Evolve and change behavior [BREVE]) was developed as a sequential series of 8 modules enabling it to be embedded within an 8-week comprehensive pulmonary rehabilitation program. When appropriate, outcomes from the pilot group (comprehensive pulmonary rehabilitation program + BREVE) were compared with those from a retrospective control group (comprehensive pulmonary rehabilitation program only). Outcomes included feedback provided by pilot study subjects, sensation of breathlessness (volunteered and endorsed descriptors of breathlessness), 6-min walk distance (6MWD), and St George Respiratory Questionnaire (SGRQ) total score. Within-group analyses were undertaken for descriptors of breathlessness (the McNemar test), whereas between-group analyses (repeated-measures analysis of variance, effect-size comparison) were conducted for the 6MWD and SGRQ total score. Pilot (n = 11) and control (n = 58) groups were not significantly different at baseline. Feedback indicated that the program structure and content were positively received. No significant changes were evident for the sensation of breathlessness or the SGRQ score (< 4 points). The 6MWD improved significantly in both groups, with the pilot group demonstrating greater gains compared with the control group (mean change of 57 m and effect size of 0.73 vs mean change of 27 m and effect size of 0.23; between groups, P = .03, effect size of 0.69). The CBT program for the perceptual experience of breathlessness was feasible and well accepted by subjects, although the protocol raised a number of methodological limitations warranting modification. A larger randomized controlled trial is needed to determine the effectiveness and longer-term outcomes. Copyright © 2015 by Daedalus Enterprises.

As healthcare moves towards a completely digital, multimedia environment there is an opportunity to provide for cost- effective, highly distributed physician access to clinical information including radiology-based imaging. In order to address this opportunity a Universal Clinical Desktop (UCD) system was developed. A UCD provides a single point of entry into an integrated view of all types of clinical data available within a network of disparate healthcare information systems. In order to explore the application of a UCD in a hospital environment, a pilot study was established with the University of California Davis Medical Center using technology from Trilix Information Systems. Within this pilot environment the information systems integrated under the UCD include a radiology information system (RIS), a picture archive and communication system (PACS) and a laboratory information system (LIS).

2016-01-01

Problems with attention and symptom distress are common clinical features reported by women who receive adjuvant chemotherapy for breast cancer. Mindfulness practice significantly improves attention and mindfulness programs significantly reduce symptom distress in patients with cancer, and, more specifically, in women with breast cancer. Recently, a pilot investigation of a music therapy program, built on core attitudes of mindfulness practice, reported significant benefits of enhanced attention and decreased negative mood and fatigue in women with breast cancer. This paper delineates the design and development of the mindfulness-based music therapy (MBMT) program implemented in that pilot study and includes clients’ narrative journal responses. Conclusions and recommendations, including recommendation for further exploration of the function of music in mindfulness practice are provided. PMID:27517966

Freezing of gait (FoG) is a common and debilitating condition in Parkinson's disease (PD) associated with executive dysfunction. A subtype of FoG does not respond to dopaminergic therapy and may be related to noradrenergic deficiency. This pilot study explores the effects of atomoxetine on gait in PD patients with dopa-unresponsive FoG using a novel paradigm for objective gait assessment. Ten patients with PD and dopa-unresponsive FoG were enrolled in this eight-week open label pilot study. Assessments included an exploratory gait analysis protocol that quantified spatiotemporal parameters during straight-away walking and turning, while performing a dual task. Clinical, and subjective assessments of gait, quality of life, and safety were also administered. The primary outcome was a validated subjective assessment for FoG (FOG-Q). Atomoxetine was well tolerated, however, no significant change was observed in the primary outcome. The gait analysis protocol correlated well with clinical scales, but not with subjective assessments. DBS patients were more likely to increase gait velocity (p = 0.033), and improved in other clinical assessments. Objective gait analysis protocols assessing gait while dual tasking are feasible and useful for this patient population, and may be superior correlates of FoG severity than subjective measures. These findings can inform future trials in this population.

To conduct a pilot study to explore the potential impact of visual feedback of personal retinal images on diabetes outcomes. Twenty-five participants with non-proliferative diabetic retinopathy and suboptimal HbA(1c) (> 53 mmol/mol; > 7%) were randomized to receive visual feedback of their own retinal images or to a control group. At baseline and 3-month follow-up, HbA(1c), standard measures of beliefs, diabetes-related distress and self-care activities were assessed. In unadjusted models, relative to controls, the intervention group showed significantly greater improvement in HbA(1c) at 3-month follow-up (-0.6% vs. +0.3%, P < 0.01), as well as enhanced motivation to improve blood glucose management (P < 0.05). This small pilot study provides preliminary evidence that visual feedback of personal retinal images may offer a practical educational strategy for clinicians in eye care services to improve diabetes outcomes in non-target compliant patients. A fully powered randomized controlled trial is required to confirm these findings and determine the optimal use of feedback to produce sustained effects. © 2013 The Authors.

This pilot study used a randomized controlled trial design to examine the feasibility and explore initial outcomes of a twice weekly, 8-session Child Directed Interaction Training (CDIT) program for children living in kinship care. Participants included 14 grandmothers and great-grandmothers with their 2- to 7-year-old children randomized either to CDIT or a waitlist control condition. Training was delivered at a local, community library with high fidelity to the training protocol. There was no attrition in either condition. After training, kinship caregivers in the CDIT condition demonstrated more positive relationships with their children during behavioral observation. The caregivers in the CDIT condition also reported clinically and statistically significant decreases in parenting stress and caregiver depression, as well as fewer externalizing child behavior problems than waitlist controls. Parent daily report measures indicated significant changes in disciplining that included greater use of limit-setting and less use of critical verbal force. Results appeared stable at 3-month follow-up. Changes in child internalizing behaviors and caregiver use of non-critical verbal force were not seen until 3-month follow-up. Results of this pilot study suggest both the feasibility of conducting full scale randomized clinical trials of CDIT in the community and the promise of this approach for providing effective parent training for kinship caregivers.

2002-01-01

The General Aviation Element of the Aviation Safety Program's Synthetic Vision Systems (SVS) Project is developing technology to eliminate low visibility induced General Aviation (GA) accidents. SVS displays present computer generated 3-dimensional imagery of the surrounding terrain on the Primary Flight Display (PFD) to greatly enhance pilot's situation awareness (SA), reducing or eliminating Controlled Flight into Terrain, as well as Low-Visibility Loss of Control accidents. SVS-conducted research is facilitating development of display concepts that provide the pilot with an unobstructed view of the outside terrain, regardless of weather conditions and time of day. A critical component of SVS displays is the appropriate presentation of terrain to the pilot. An experimental study has been conducted at NASA Langley Research Center (LaRC) to explore and quantify the relationship between the realism of the terrain presentation and resulting enhancements of pilot SA and pilot performance. Composed of complementary simulation and flight test efforts, Terrain Portrayal for Head-Down Displays (TP-HDD) experiments will help researchers evaluate critical terrain portrayal concepts. The experimental effort is to provide data to enable design trades that optimize SVS applications, as well as develop requirements and recommendations to facilitate the certification process. This paper focuses on the experimental set-up and preliminary qualitative results of the TP-HDD simulation experiment. In this experiment a fixed based flight simulator was equipped with various types of Head Down flight displays, ranging from conventional round dials (typical of most GA aircraft) to glass cockpit style PFD's. The variations of the PFD included an assortment of texturing and Digital Elevation Model (DEM) resolution combinations. A test matrix of 10 terrain display configurations (in addition to the baseline displays) were evaluated by 27 pilots of various backgrounds and experience levels. Qualitative (questionnaires) and quantitative (pilot performance and physiological) data were collected during the experimental runs. Preliminary results indicate that all of the evaluation pilots favored SVS displays over standard gauges, in terms of terrain awareness, SA, and perceived pilot performance. Among the terrain portrayal concepts tested, most pilots preferred the higher-resolution DEM. In addition, with minimal training, low-hour VFR evaluation pilots were able to negotiate a precision approach using SVS displays with a tunnel in the sky guidance concept.

To improve informed medical decision-making, principles for family-centered neonatal care recommend that parents have access to their child's medical record on an ongoing basis during neonatal intensive unit care (NICU) hospitalization. Currently, many NICUs do not allow independent parent access to their child's electronic medical record (EMR) during hospitalization. We undertook a cross-sectional survey pilot study of medical professionals and parents to explore opinions regarding this practice. Inclusion criteria: 18-years old, English-literate, legal guardian of patients admitted to the NICU for 14 days. NICU medical professionals included physicians, nurse practitioners, nurses, and respiratory therapists. Medical professionals believed parent access would make their work more difficult, increase time documenting and updating families, making them more liable to litigation and hesitant to chart sensitive information. However, parents felt that they lacked control over their child's care and desired direct access to the EMR. Parents believed this would improve accuracy of their child's medical chart, and increase advocacy and understanding of their child's illness. NICU parents and medical professionals have differing perspectives on independent parental access to their child's EMR. More research is needed to explore the potential of independent parental EMR access to further improve family-centered neonatal care.

Bovine tuberculosis, caused by Mycobacterium bovis, is a zoonotic disease of international public health importance. Ante-mortem surveillance is essential for control; however, current surveillance tests are hampered by limitations affecting ease of use or quality of results. There is an emerging interest in human and veterinary medicine in diagnosing disease via identification of volatile organic compounds produced by pathogens and host-pathogen interactions. The objective of this pilot study was to explore application of existing human breath collection and analysis methodologies to cattle as a means to identify M. bovis infection through detection of unique volatile organic compounds or changes in the volatile organic compound profiles present in breath. Breath samples from 23 male Holstein calves (7 non-infected and 16 M. bovis-infected) were collected onto commercially available sorbent cartridges using a mask system at 90 days post-inoculation with M. bovis. Samples were analyzed using gas chromatography-mass spectrometry, and chromatographic data were analyzed using standard analytical chemical and metabolomic analyses, principle components analysis, and a linear discriminant algorithm. The findings provide proof of concept that breath-derived volatile organic compound analysis can be used to differentiate between healthy and M. bovis-infected cattle. PMID:24586655

The ARC pilot plant conceptual design study has been extended to explore solutions for managing heat exhaust resulting from 525 MW of fusion power in a compact (R 3.3 m) tokamak. Superconducting poloidal field coils are configured to produce double-null equilibria that support X-point target divertors while maintaining the original core plasma shape and toroidal field coil size. Long outer divertor legs are appended to the original vacuum vessel, providing both large surface areas for surface dissipation of radiative heat and significantly reduced neutron damage for divertor components. A molten salt FLiBe blanket adequately shields all superconductors and functions as a tritium breeder, with advanced neutronics calculations indicating a tritium breeding ratio of 1.08. In addition, FLiBe is used as the active coolant for the entire vessel. A tungsten swirl-tube cooling channel is implemented in the divertor, capable of exhausting 12 MW/m2, heat flux while keeping total FliBe pumping power below 1% of fusion power. Finally, three novel diagnostics are explored: Cherenkov radiation emitted in FLiBe to measure fusion reaction rate, microwave interferometry to measure divertor detachment front location, and IR imaging through the FLiBe blanket to monitor selected divertor ``hotspots.''

2017-01-01

The aim of this study was to explore the potential of ZORA robot-based interventions in rehabilitation and special education for children with severe physical disabilities. A two-centre explorative pilot study was carried out over a 2.5-month period involving children with severe physical disabilities with a developmental age ranging from 2 to 8 years. Children participated in six sessions with the ZORA robot in individual or in group sessions. Qualitative and quantitative methods were used to collect data on aspects of feasibility, usability, barriers and facilitators for the child as well as for the therapist and to obtain an indication of the effects on playfulness and the achievement of goals. In total, 17 children and seven professionals participated in the study. The results of this study show a positive contribution of ZORA in achieving therapy and educational goals. Moreover, sessions with ZORA were indicated as playful. Three main domains were indicated to be the most promising for the application of ZORA: movement skills, communication skills and cognitive skills. Furthermore, ZORA can contribute towards eliciting motivation, concentration, taking initiative and improving attention span of the children. On the basis of the results of the study, it can be concluded that ZORA has potential in therapy and education for children with severe physical disabilities. More research is needed to gain insight into how ZORA can be applied best in rehabilitation and special education. PMID:28837499

This study was designed to pilot a survey to explore players' perception of home advantage in a rugby league. Twenty-seven players from one team with an identified home advantage believed a home advantage existed as a result of their home crowd (52%), family and friends' support (41%), normal travel (45%) and sleeping arrangements (37%), home weather conditions (48%), and familiarity with playing amenities (37%). However, the players were less definite about influences while playing away from home. The current sample of players identified differing influences, highlighting individual variations in perceived determinants. Individual interviews or focus groups will be required for further exploration.

Adaptive State Predictor Based Human Operator Modeling on Longitudinal and Lateral Control

Trujillo, Anna C.; Gregory, Irene M.; Hempley, Lucas E.

2015-01-01

Control-theoretic modeling of the human operator dynamic behavior in manual control tasks has a long and rich history. In the last two decades, there has been a renewed interest in modeling the human operator. There has also been significant work on techniques used to identify the pilot model of a given structure. The purpose of this research is to attempt to go beyond pilot identification based on collected experimental data and to develop a predictor of pilot behavior. An experiment was conducted to categorize these interactions of the pilot with an adaptive controller compensating during control surface failures. A general linear in-parameter model structure is used to represent a pilot. Three different estimation methods are explored. A gradient descent estimator (GDE), a least squares estimator with exponential forgetting (LSEEF), and a least squares estimator with bounded gain forgetting (LSEBGF) used the experiment data to predict pilot stick input. Previous results have found that the GDE and LSEEF methods are fairly accurate in predicting longitudinal stick input from commanded pitch. This paper discusses the accuracy of each of the three methods - GDE, LSEEF, and LSEBGF - to predict both pilot longitudinal and lateral stick input from the flight director's commanded pitch and bank attitudes.

Shared responsibility for managing fatigue: Hearing the pilots

O’Keeffe, Karyn M.; Signal, T. Leigh; Gander, Philippa H.

2018-01-01

In commercial aviation, fatigue is defined as a physiological state of reduced mental or physical performance capability resulting from sleep loss, extended wakefulness, circadian phase, and/or workload. The International Civil Aviation Organisation mandates that responsibility for fatigue risk management is shared between airline management, pilots, and support staff. However, to date, the majority of research relating to fatigue mitigations in long range operations has focused on the mitigations required or recommended by regulators and operators. Little research attention has been paid to the views or operational experience of the pilots who use these (or other) mitigations. This study focused on pilots’ views and experiences of in-flight sleep as the primary fatigue mitigation on long range flights. It also sought information about other fatigue mitigation strategies they use. Thematic analysis was used to explore written comments from diary and survey data collected during long range and ultra-long range trips (N = 291 pilots on three different aircraft types, 17 different out-and-back trips, and four airlines based on three continents). The findings indicate that the recommended fatigue mitigation strategies on long-haul flights (particularly in-flight sleep) are effective and well-utilised, consistent with quantitative findings from the same trips. Importantly however, the analyses also highlight areas that require further investigation, including flight preparation strategies in relation to the uncertainty of in-flight break allocation. There were two strategies for sleep prior to a flight: maximising sleep if pilots were expecting later breaks in the flight; or minimising sleep if they were expecting breaks earlier or at unfavourable times in the circadian cycle. They also provide a broader view of the factors that affect the amount and quality of pilots’ in-flight sleep, about which evidence has previously been largely anecdotal. The study underscores the value of including the views and experience of pilots in fatigue risk management. PMID:29782533

The Mariani Nursing Career Satisfaction Scale (MNCSS) was developed to explore the influence of mentoring on career satisfaction of registered nurses (RNs). A review of the literature revealed no contemporary valid and reliable measure of career satisfaction. The MNCSS is a semantic differential of 16 opposite adjective pairs on which participants rate feelings about their nursing career. The MNCSS was used in a pilot study and three major studies exploring career satisfaction of RNs. Validity, reliability, and exploratory factor analysis (FA) were computed to explore the internal structure of the instrument. The newly developed instrument had a content validity index (CVI) of .84 and Cronbach's alpha internal consistency reliabilities of .93-.96 across three major studies. Exploratory FA (N = 496) revealed a univocal instrument with one factor that explains 57.8% of the variance in career satisfaction scores. The MNCSS is a valid and reliable instrument for measuring career satisfaction. FA of the combined data from three studies yielded one factor that measures the concept of career satisfaction.

Recently our laboratory team focused on training five individuals with complete spinal cord injuries for an overground FES bike race in the 2016 Cybathlon held in Zurich Switzerland. A unique advantage team Cleveland had over other teams was the use of implanted pulse generators that provide more selective activation of muscles compared to standard surface stimulation. The advancements in muscle strength and endurance and ultimately cycling power our pilots made during this training period helped propel our competing pilot to win gold at the Cybathlon and allowed our pilots to ride their bikes outside within their communities. Such positive outcomes has encouraged us to further explore more widespread use of FES overground cycling as a rehabilitative tool for those with spinal cord injuries. This review will describes our approach to this race including information on the pilots, stimulation strategy, bike details and training program. PMID:29299221

Researchers at the National Aeronautics and Space Administration (NASA) Ames Research Center and Langley Research Center are jointly investigating issues associated with potential concepts, or configurations, in which a single pilot might operate under conditions that are currently reserved for a minimum of two pilots. As part of early efforts, NASA Ames Research Center hosted a technical interchange meeting in order to gain insight from members of the aviation community regarding single-pilot operations (SPO). The meeting was held on April 10-12, 2012 at NASA Ames Research Center. Professionals in the aviation domain were invited because their areas of expertise were deemed to be directly related to an exploration of SPO. NASA, in selecting prospective participants, attempted to represent various relevant sectors within the aviation domain. Approximately 70 people representing government, academia, and industry attended. A primary focus of this gathering was to consider how tasks and responsibilities might be re-allocated to allow for SPO.

Gasoline compression ignition concepts with the majority of the fuel being introduced early in the cycle are known as partially premixed combustion (PPC). Previous research on single- and multi-cylinder engines has shown that PPC has the potential for high thermal efficiency with low NOx and soot emissions. A variety of fuel injection strategies has been proposed in the literature. These injection strategies aim to create a partially stratified charge to simultaneously reduce NOx and soot emissions while maintaining some level of control over the combustion process through the fuel delivery system. The impact of the direct injection strategy to createmore » a premixed charge of fuel and air has not previously been explored, and its impact on engine efficiency and emissions is not well understood. This paper explores the effect of sweeping the direct injected pilot timing from -91° to -324° ATDC, which is just after the exhaust valve closes for the engine used in this study. During the sweep, the pilot injection consistently contained 65% of the total fuel (based on command duration ratio), and the main injection timing was adjusted slightly to maintain combustion phasing near top dead center. A modern four cylinder, 1.9 L diesel engine with a variable geometry turbocharger, high pressure common rail injection system, wide included angle injectors, and variable swirl actuation was used in this study. The pistons were modified to an open bowl configuration suitable for highly premixed combustion modes. The stock diesel injection system was unmodified, and the gasoline fuel was doped with a lubricity additive to protect the high pressure fuel pump and the injectors. The study was conducted at a fixed speed/load condition of 2000 rpm and 4.0 bar brake mean effective pressure (BMEP). The pilot injection timing sweep was conducted at different intake manifold pressures, swirl levels, and fuel injection GTP-15-1067, Dempsey 2 pressures. The gasoline used in this study has relatively high fuel reactivity with a research octane number of 68. The results of this experimental campaign indicate that the highest brake thermal efficiency and lowest emissions are achieved simultaneously with the earliest pilot injection timings (i.e., during the intake stroke).« less

This paper explores methodology issues encountered in the analysis of flightcrew communications in aviation simulation research. Examples are provided by two recent studies which are compared on three issues: level of analysis, data definition, and interpretation of the results. The data discussed were collected in a study comparing two levels of aircraft automation. The first example is an investigation of how pilots' information transfer strategies differed as a function of automation during low and high-workload flight phases. The second study focuses on how crews managed actions in the two aircraft during a ten minute, high-workload flight segment. Results indicated that crews in the two aircraft differed in their strategies of information and action management. The differences are discussed in terms of their operational and research significance.

Return-to-work (RTW) rates after spinal cord injury (SCI) in the USA are very low and are continuing to decline. Previous research has attempted to identify factors facilitating RTW; however, the phenomenon of RTW involves many personal factors and predicting RTW success remains difficult. The purpose of this pilot study was to explore the factors facilitating adults with SCI rejoining the workforce in an urban area in order to identify items that may be emphasized in the rehabilitation process. The study was completed using qualitative methods. Four adults who had acquired a traumatic SCI in adulthood and were currently employed participated. Their experiences in RTW after injury were collected via semi-structured interviews and photography of assistive devices. The most common facilitating factor was motivation, with family and rehabilitation professionals serving as extrinsic motivators. Other facilitators were resources and perceived benefits. Motivation and resources were important facilitators, including rehabilitation professional's personal influence and therapies, and resource assistance from state agencies. The results indicate that practitioners can play an important role in influencing RTW, and resources from state agencies are helpful when individuals know how to access and utilize them. Assistive technology supports successful return to work after SCI. Motivation strongly influences return to work after SCI and can be influenced by rehabilitation professionals, family and community members. Patients should be well informed about how to access assistance programs such as vocational rehabilitation.

One of the most thoroughly studied aspects of prosocial workplace behavior is organizational citizenship behavior (OCB). Yet, the definition of OCB seems to overlook the fact that help-giving acts may be of different types with different consequences for both giver and recipient. The present research explores workplace help-giving behavior by investigating the importance of gender as a factor that facilitates or inhibits specific types of help that empower and disempower independent coping: autonomy- and dependency-oriented help, respectively. A pilot and two following studies were conducted. The pilot study empirically assessed which acts would be clearly perceived by participants as representing both types of help. Then, using the descriptions of these acts, Study 1 examined which type of help would be perceived as most likely to be given by a male or female employee to a male or female colleague in a sample of 226 participants (78% women). Study 2 explored which type of help participants perceived as one they would rather receive from a male or female helper in a sample of 170 participants (65% women). Our findings indicate that male and female respondents who rated men giving help were more likely to expect them to give autonomy-oriented help, especially to women. There were no significant differences in dependency-oriented help. Further, women preferred to receive more autonomy-oriented help than men did, regardless of the help-giver's gender; no significant results were found for men. Implications for OCB and workplace power relations are discussed.
