Those most at risk during heat waves and floods - are often the socio-economically vulnerable. Yet very few studies exist of indoor temperatures during heat waves or of standing water events at the neighborhood level during extreme events. ISeeChange, a community weather and climate journal, is developing tools and testing techniques in a series of community pilots in Harlem and New Orleans to assess if a combination of citizen science and journalism can bridge the gap. Our consortium of media (WNYC,Adapt NYC, ISeeChange), scientists (CUNY, CoCoRaHS, NASAJPL), and community partners (WE ACT for Environmental Justice, tenant, and neighborhood associations) are collaborating to engage with residents, report radio stories, as well as develop scientifically valuable information for decision-making. Community volunteers place temperature and humidity sensors inside residences (Harlem) or photograph standing water using specific methodologies (New Orleans). Sensor data, photographs, and text documenting the impacts of extreme weather on residents are posted on the ISeeChange platform via mobile app or community ambassadors. Preliminary results of the Harlem pilot show that indoor temperatures are far more stable than outdoor temperatures, so can be both cooler during the day but warmer at night; preliminary work on the New Orleans pilot is set to begin in fall 2016. A full analysis of the Harlem pilot will be presented along with preliminary results of the New Orleans pilot.

O'Connor-Dreher, Ryan; Roberts, Z.; Ziccardi, J.; Vu, K-P. L.; Strybel, T.; Koteskey, Robert William; Lachter, Joel B.; Vi Dao, Quang; Johnson, Walter W.; Battiste, V.

2013-01-01

The number of crew members in commercial flights has decreased to two members, down from the five-member crew required 50 years ago. One question of interest is whether the crew should be reduced to one pilot. In order to determine the critical factors involved in safely transitioning to a single pilot, research must examine whether any performance deficits arise with the loss of a crew member. With a concrete understanding of the cognitive and behavioral role of a co-pilot, aeronautical technologies and procedures can be developed that make up for the removal of the second aircrew member. The current project describes a pre-study walkthrough process that can be used to help in the development of scenarios for testing future concepts and technologies for single pilot operations. Qualitative information regarding the tasks performed by the pilots can be extracted with this technique and adapted for future investigations of single pilot operations.

A tutorial on pilot studies: the what, why and how

PubMed Central

2010-01-01

Pilot studies for phase III trials - which are comparative randomized trials designed to provide preliminary evidence on the clinical efficacy of a drug or intervention - are routinely performed in many clinical areas. Also commonly know as "feasibility" or "vanguard" studies, they are designed to assess the safety of treatment or interventions; to assess recruitment potential; to assess the feasibility of international collaboration or coordination for multicentre trials; to increase clinical experience with the study medication or intervention for the phase III trials. They are the best way to assess feasibility of a large, expensive full-scale study, and in fact are an almost essential pre-requisite. Conducting a pilot prior to the main study can enhance the likelihood of success of the main study and potentially help to avoid doomed main studies. The objective of this paper is to provide a detailed examination of the key aspects of pilot studies for phase III trials including: 1) the general reasons for conducting a pilot study; 2) the relationships between pilot studies, proof-of-concept studies, and adaptive designs; 3) the challenges of and misconceptions about pilot studies; 4) the criteria for evaluating the success of a pilot study; 5) frequently asked questions about pilot studies; 7) some ethical aspects related to pilot studies; and 8) some suggestions on how to report the results of pilot investigations using the CONSORT format.

Kim, Rachel E.; Becker, Kimberly D.; Stephan, Sharon H.; Hakimian, Serop; Apocada, Dee; Escudero, Pia V.; Chorpita, Bruce F.

2015-01-01

Schools function as the major provider of mental health services (MHS) for youth, but can struggle with engaging them in services. School nurses are well-positioned to facilitate referrals for MHS. This pilot study examined the feasibility, acceptability, and preliminary efficacy of an engagement protocol (EP) designed to enhance school nurses’ utilization of evidence-based engagement practices when referring youth to MHS. Participants were six school nurses and twenty-five adolescents in a large, urban school district. School nurses reported positive attitudes towards the EP, suggesting that they found it feasible and acceptable. Though there were small increases in school nurses’ use of engagement practices and in adolescents’ readiness for services following training, due to limited sample size, differences were not statistically significant. Still, pilot results suggest preliminary efficacy of training school nurses to strategically implement evidence-based engagement practices to increase adolescents’ engagement in MHS. PMID:26251671

Evon, Donna M; Golin, Carol E; Ruffin, Rachel; Fried, Michael W

2017-06-01

Psychosocial interventions for patients with chronic hepatitis C viral (HCV) infection are needed to attenuate the impact of extrahepatic symptoms, comorbid conditions, and treatment side effects on HCV health outcomes. We adapted empirically-supported interventions for similar patient populations to develop a Cognitive Behavioral Coping Skills group intervention for HCV patients (CBCS-HCV) undergoing treatment. The objectives of this paper are to describe the research activities associated with CBCS-HCV development and pilot testing, including: (1) formative work leading to intervention development; (2) preliminary study protocol; and (3) pilot feasibility testing of the intervention and study design. Formative work included a literature review, qualitative interviews, and adaption, development, and review of study materials. A preliminary study protocol is described. We evaluate the feasibility of conducting a randomized controlled trial (RCT) of the CBCS-HCV with 12 study participants in Wave 1 testing to examine: (a) feasibility of intervention delivery; (b) patient acceptability; (c) recruitment, enrollment, retention; (d) feasibility of conducting a RCT; (d) therapist protocol fidelity; and (e) feasibility of data collection. Numerous lessons were learned. We found very high rates of data collection, participant attendance, engagement, retention and acceptability, and therapist protocol fidelity. We conclude that many aspects of the CBCS-HCV intervention and study protocol were highly feasible. The greatest challenge during this Wave 1 pilot study was efficiency of participant enrollment due to changes in standard of care treatment. These findings informed two additional waves of pilot testing to examine effect sizes and potential improvements in clinical outcomes, with results forthcoming.

Engaging Overweight Adolescents in a Health and Fitness Program Using Wearable Activity Trackers.

PubMed

Wilson, Marian; Ramsay, Samantha; Young, Kimberly J

Our objectives were to (a) examine feasibility and receptivity of overweight adolescents joining a community-based group fitness program and (b) test preliminary efficacy of a 12-week pilot intervention designed to promote health, fitness, and self-efficacy for the identified teens. The 12-week fitness program for overweight adolescents was developed and included planned physical activities, nutrition classes, and goal-setting sessions. A one-group pre-/posttest study design evaluated 20 participants from grades 10 through 12 who enrolled in the program pilot study. Participants were given a wearable activity tracker that captured data using an Internet-based platform. Outcome measures included body mass index, screen time, fitness, and cardiovascular measures. A community fitness program for overweight adolescents was successfully implemented. High school students were receptive to the intervention and reported high program satisfaction. Positive effects included measurements of strength, systolic blood pressure, weight, and screen time behaviors. This study provides evidence to support the feasibility, acceptance, and preliminary effects of the pilot program with overweight adolescents.

Recommendations for Planning Pilot Studies in Clinical and Translational Research

Moore, Charity G.; Carter, Rickey E.; Nietert, Paul J.; Stewart, Paul W.

2011-01-01

Abstract  Advances in clinical and translation science are facilitated by building on prior knowledge gained through experimentation and observation. In the context of drug development, preclinical studies are followed by a progression of phase I through phase IV clinical trials. At each step, the study design and statistical strategies are framed around research questions that are prerequisites for the next phase. In other types of biomedical research, pilot studies are used for gathering preliminary support for the next research step. However, the phrase “pilot study” is liberally applied to projects with little or no funding, characteristic of studies with poorly developed research proposals, and usually conducted with no detailed thought of the subsequent study. In this article, we present a rigorous definition of a pilot study, offer recommendations for the design, analysis and sample size justification of pilot studies in clinical and translational research, and emphasize the important role that well‐designed pilot studies play in the advancement of science and scientific careers.

2016-01-01

We replicated and extended a study by Spruyt and Hermans (2008) in which picture primes engendered an evaluative-priming effect on the pronunciation of target words. As preliminary steps, we assessed data reproducibility of the original study, conducted Pilot Study I to identify highly semantically related prime-target pairs, reanalyzed the original data excluding such pairs, conducted Pilot Study II to demonstrate that we can replicate traditional associative priming effects in the pronunciation task, and conducted Pilot Study III to generate relatively unrelated sets of prime pictures and target words. The main study comprised three between-participants conditions: (1) a close replication of the original study, (2) the same condition excluding highly related prime-target pairs, and (3) a condition based on the relatively unrelated sets of prime pictures and target words developed in Pilot Study III. There was little evidence for an evaluative priming effect independent of semantic relatedness.

A preliminary look at an optimal multivariable design for propulsion-only flight control of jet-transport aircraft

NASA Technical Reports Server (NTRS)

Azzano, Christopher P.

1992-01-01

Control of a large jet transport aircraft without the use of conventional control surfaces was studied. Engine commands were used to attempt to recreate the forces and moments typically provided by the elevator, ailerons, and rudder. Necessary conditions for aircraft controllability were developed pertaining to aircraft configuration such as the number of engines and engine placement. An optimal linear quadratic regulator controller was developed for the Boeing 707-720, in particular, for regulation of its natural dynamic modes. The design used a method of assigning relative weights to the natural modes, i.e., phugoid and dutch roll, for a more intuitive selection of the cost function. A prototype pilot command interface was then integrated into the loop based on pseudorate command of both pitch and roll. Closed loop dynamics were evaluated first with a batch linear simulation and then with a real time high fidelity piloted simulation. The NASA research pilots assisted in evaluation of closed loop handling qualities for typical cruise and landing tasks. Recommendations for improvement on this preliminary study of optimal propulsion only flight control are provided.

2005-01-01

This report summarizes the initial work accomplished by the ACCESS 5 Human System Integration (HSI) team to identify Unmanned Aircraft System (UAS) Pilot Knowledge, Skill and Ability (KSA), Training and Medical requirements. To derive this information the following tasks were accomplished: a) Mission and Function analyses were performed; b) Applicable FARs and FAA Advisory Circulars (ACs) were reviewed; c) Meetings were conducted with NASA and FAA Human Factors personnel; d) Surveys were completed by ACCESS 5 HSI Working group UA Pilots; e) Coordination meetings were conducted with the ACCESS 5 Policy IPT. The results of these efforts were used to develop a summary of the current qualifications. for an individual to function as a Pilot In Command (PIC) for UAs currently flown by UNITE companies, to develop preliminary Pilot KSAs for each phase of flight, and to delineate preliminary Pilot Training and Medical requirements. These results are to be provided to the Policy IPT to support their development of recommendations for UA Pilot Rating Criteria, training and medical qualifications. It is expected that the initially an instrument rated pilot will be required to serve as the PIC. However, as operational experience is gained, and automation is applied to accomplish various system functions, it is expected that pilot rating criteria could be lessened.

Understanding Treatment Burden and Quality of Life Impact of Participating in an Early-Phase Pediatric Oncology Clinical Trial: A Pilot Study.

PubMed

Crane, Stacey; Backus, Lori; Stockman, Beth; Carpenter, Janet S; Lin, Li; Haase, Joan

Early-phase clinical trials (EPTs) have led to new, more effective treatment options for children with cancer. Despite the extensive use of EPTs in pediatric oncology, little is known about parent and child experiences during EPT participation. The purposes of this pilot study were to assess the feasibility and preliminary results of having children with cancer and their parents complete measures of treatment burden and quality of life (QOL) concurrent with EPT participation. In this descriptive, longitudinal, pilot study, parents and children were followed for the first 60 days of an EPT. Feasibility was assessed by participant enrollment and retention and completion of measures. Measures completed included the following: demographic form (completed at baseline); Diary of Trial Experiences to capture treatment burden (completed ongoing); and PedsQL™ Quality of Life Inventories, Cancer Modules, and Family Impact Module (completed at baseline, post-first disease evaluation, and off-study). Data were analyzed using descriptive statistics. Feasibility goals of enrollment, retention, and measure completion were partially met. Preliminary treatment burden and QOL results are provided. While QOL assessments may provide insight into EPT experiences, future studies need to be conducted at multiple sites and enrollment goals must account for participant attrition.

The results of a fixed-base simulator study of the effects of variable longitudinal control-system dynamics on pilot opinion are presented and compared with flight-test data. The control-system variables considered in this investigation included stick force per g, time constant, and dead-band, or stabilizer breakout force. In general, the fairly good correlation between flight and simulator results for two pilots demonstrates the validity of fixed-base simulator studies which are designed to complement and supplement flight studies and serve as a guide in control-system preliminary design. However, in the investigation of certain problem areas (e.g., sensitive control-system configurations associated with pilot- induced oscillations in flight), fixed-base simulator results did not predict the occurrence of an instability, although the pilots noted the system was extremely sensitive and unsatisfactory. If it is desired to predict pilot-induced-oscillation tendencies, tests in moving-base simulators may be required. It was found possible to represent the human pilot by a linear pilot analog for the tracking task assumed in the present study. The criterion used to adjust the pilot analog was the root-mean-square tracking error of one of the human pilots on the fixed-base simulator. Matching the tracking error of the pilot analog to that of the human pilot gave an approximation to the variation of human-pilot behavior over a range of control-system dynamics. Results of the pilot-analog study indicated that both for optimized control-system dynamics (for poor airplane dynamics) and for a region of good airplane dynamics, the pilot response characteristics are approximately the same.

Simulation Evaluation of Pilot Inputs for Real Time Modeling During Commercial Flight Operations

NASA Technical Reports Server (NTRS)

Martos, Borja; Ranaudo, Richard; Oltman, Ryan; Myhre, Nick

Aircraft dynamics characteristics can only be identified from flight data when the aircraft dynamics are excited sufficiently. A preliminary study was conducted into what types and levels of manual piloted control excitation would be required for accurate Real-Time Parameter IDentification (RTPID) results by commercial airline pilots. This includes assessing the practicality for the pilot to provide this excitation when cued, and to further understand if pilot inputs during various phases of flight provide sufficient excitation naturally. An operationally representative task was evaluated by 5 commercial airline pilots using the NASA Ice Contamination Effects Flight Training Device (ICEFTD). Results showed that it is practical to use manual pilot inputs only as a means of achieving good RTPID in all phases of flight and in flight turbulence conditions. All pilots were effective in satisfying excitation requirements when cued. Much of the time, cueing was not even necessary, as just performing the required task provided enough excitation for accurate RTPID estimation. Pilot opinion surveys reported that the additional control inputs required when prompted by the excitation cueing were easy to make, quickly mastered, and required minimal training.

Preliminary Effect of Synthetic Vision Systems Displays to Reduce Low-Visibility Loss of Control and Controlled Flight Into Terrain Accidents

NASA Technical Reports Server (NTRS)

Glaab, Louis J.; Takallu, Mohammad A.

2002-01-01

An experimental investigation was conducted to study the effectiveness of Synthetic Vision Systems (SVS) flight displays as a means of eliminating Low Visibility Loss of Control (LVLOC) and Controlled Flight Into Terrain (CFIT) accidents by low time general aviation (GA) pilots. A series of basic maneuvers were performed by 18 subject pilots during transition from Visual Meteorological Conditions (VMC) to Instrument Meteorological Conditions (IMC), with continued flight into IMC, employing a fixed-based flight simulator. A total of three display concepts were employed for this evaluation. One display concept, referred to as the Attitude Indicator (AI) replicated instrumentation common in today's General Aviation (GA) aircraft. The second display concept, referred to as the Electronic Attitude Indicator (EAI), featured an enlarged attitude indicator that was more representative of a glass display that also included advanced flight symbology, such as a velocity vector. The third concept, referred to as the SVS display, was identical to the EAI except that computer-generated terrain imagery replaced the conventional blue-sky/brown-ground of the EAI. Pilot performance parameters, pilot control inputs and physiological data were recorded for post-test analysis. Situation awareness (SA) and qualitative pilot comments were obtained through questionnaires and free-form interviews administered immediately after the experimental session. Initial pilot performance data were obtained by instructor pilot observations. Physiological data (skin temperature, heart rate, and muscle flexure) were also recorded. Preliminary results indicate that far less errors were committed when using the EAI and SVS displays than when using conventional instruments. The specific data example examined in this report illustrates the benefit from SVS displays to avoid massive loss of SA conditions. All pilots acknowledged the enhanced situation awareness provided by the SVS display concept. Levels of pilot stress appear to be correlated with skin temperature measurements.

2015-12-01

With passage and implementation of the Affordable Health Care Act, more vulnerable segments of the U.S. population will now have access to regular health care and increased opportunities to participate in biomedical research. Yet, access to new groups brings with it new responsibilities for investigators, most importantly, reducing burdens for participants. Data collected through this small pilot study suggest several preliminary but potentially important findings when working with adults from low-income populations: First, while all participants read some parts of the consent forms (55%), only a minority reported reading the entire form (45%); second, 73% of participants reported understanding the study very well whereas only 27% reported understanding the study "a little"; third, there was a slight reported advantage of the simplified form over the regular form; however, this difference varied by section. Relatedly, other research has shown a high incidence of persons reading none of the consent form, but signing a statement that they have read and understood the study. Why does this occur? What are we teaching people when we request that they sign a consent form they have chosen not to read? What are the ethical and regulatory implications? Embedded ethics studies such as this one, although pilot and preliminary in nature, offer a number of advantages, such as stimulating additional scientific inquiry as well as challenging established institutional practices. © The Author(s) 2015.

Jackson, E. B.; Rivers, Robert A.; Bailey, Melvin L.

1993-01-01

A man-in-the-loop simulation study of the handling qualities of the HL-20 lifting-body vehicle was made in a fixed-base simulation cockpit at NASA Langley Research Center. The purpose of the study was to identify and substantiate opportunities for improving the original design of the vehicle from a handling qualities and landing performance perspective. Using preliminary wind-tunnel data, a subsonic aerodynamic model of the HL-20 was developed. This model was adequate to simulate the last 75-90 s of the approach and landing. A simple flight-control system was designed and implemented. Using this aerodynamic model as a baseline, visual approaches and landings were made at several vehicle lift-to-drag ratios. Pilots rated the handling characteristics of each configuration using a conventional numerical pilot-rating scale. Results from the study showed a high degree of correlation between the lift-to-drag ratio and pilot rating. Level 1 pilot ratings were obtained when the L/D ratio was approximately 3.8 or higher.

Kumar, Devesh; Singh, Jai Vir; Kharwar, Poonam S.

2011-01-01

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

Latorella, Kara; Pliske, Rebecca; Hutton, Robert; Chrenka, Jason

2001-01-01

This report presents preliminary findings from a cognitive task analysis (CTA) of business aviation piloting. Results describe challenging weather-related aviation decisions and the information and cues used to support these decisions. Further, these results demonstrate the role of expertise in business aviation decision-making in weather flying, and how weather information is acquired and assessed for reliability. The challenging weather scenarios and novice errors identified in the results provide the basis for experimental scenarios and dependent measures to be used in future flight simulation evaluations of candidate aviation weather information systems. Finally, we analyzed these preliminary results to recommend design and training interventions to improve business aviation decision-making with weather information. The primary objective of this report is to present these preliminary findings and to document the extended CTA methodology used to elicit and represent expert business aviator decision-making with weather information. These preliminary findings will be augmented with results from additional subjects using this methodology. A summary of the complete results, absent the detailed treatment of methodology provided in this report, will be documented in a separate publication.

This is a report of post-treatment findings from a completed randomized pilot study testing the preliminary efficacy of The Mothers and Toddlers Program (MTP), a 12 week attachment-based individual parenting therapy for mothers enrolled in substance abuse treatment and caring for children ages birth to 36 months. Forty-seven mothers were randomized to MTP versus the Parent Education Program (PE) – a comparison intervention providing individual case management and child guidance brochures. At post-treatment, MTP mothers demonstrated better reflective functioning in the Parent Development Interview, representational coherence and sensitivity, and caregiving behavior than PE mothers. Partial support was also found for proposed mechanisms of change in the MTP model. Together, preliminary findings suggest that attachment-based interventions may be more effective than traditional parent training for enhancing relationships between substance using women and their young children.

The effect of shared information is assessed in terms of pilot/controller negotiation and shared situation awareness. Pilot goals and situation awareness requirements are developed and compared against those of air traffic controllers to identify areas of common and competing interest. A part-task simulator experiment is described which probes pilot/controller interaction in areas where common information has the potential to lead to contention, as identified in the comparative analysis. Preliminary results are presented which suggest that shared information can effect more collaborative interaction between pilots and air traffic controllers.

1996-01-01

The Life Sciences, Microgravity Science and Spacelab Mission contains a number of human experiments directed toward identifying the functional, metabolic and neurological characteristics of muscle weakness and atrophy during space flight. To ensure the successful completion of the flight experiments, a ground-based pilot study, designed to mimic the flight protocols as closely as possible, was carried out in the head-down tilt bed rest model. This report records the rationales, procedures, preliminary results and estimated value of the pilot study, the first of its kind, for 12 of the 13 planned experiments in human research. The bed rest study was conducted in the Human Research Facility at Ames Research Center from July 11 - August 28, 1995. Eight healthy male volunteers performed the experiments before, during and after 17 days bed rest. The immediate purposes of this simulation were to integrate the experiments, provide data in a large enough sample for publication of results, enable investigators to review individual experiments in the framework of a multi-disciplinary study and relay the experience of the pilot study to the mission specialists prior to launch.

Linking the Pilot Structural Model and Pilot Workload

NASA Technical Reports Server (NTRS)

Bachelder, Edward; Hess, Ronald; Aponso, Bimal; Godfroy-Cooper, Martine

2018-01-01

Behavioral models are developed that closely reproduced pulsive control response of two pilots using markedly different control techniques while conducting a tracking task. An intriguing find was that the pilots appeared to: 1) produce a continuous, internally-generated stick signal that they integrated in time; 2) integrate the actual stick position; and 3) compare the two integrations to either issue or cease a pulse command. This suggests that the pilots utilized kinesthetic feedback in order to sense and integrate stick position, supporting the hypothesis that pilots can access and employ the proprioceptive inner feedback loop proposed by Hess's pilot Structural Model. A Pilot Cost Index was developed, whose elements include estimated workload, performance, and the degree to which the pilot employs kinesthetic feedback. Preliminary results suggest that a pilot's operating point (parameter values) may be based on control style and index minimization.

An airborne FLIR detection and warning system for low altitude wind shear

NASA Technical Reports Server (NTRS)

Sinclair, Peter C.; Kuhn, Peter M.

1991-01-01

It is shown through some preliminary flight measurement research that a forward looking infrared radiometer (FLIR) system can be used to successfully detect the cool downdraft of downbursts (microbusts/macrobursts) and thunderstorm gust front outflows that are responsible for most of the low altitude wind shear (LAWS) events. The FLIR system provides a much greater safety margin for the pilot than that provided by reactive designs such as inertial air speed systems. Preliminary results indicate that an advanced airborne FLIR system could provide the pilot with remote indication of microburst (MB) hazards along the flight path ahead of the aircraft. Results of a flight test of a prototype FLIR system show that a minimum warning time of one to four minutes (5 to 10 km), depending on aircraft speed, is available to the pilot prior to the microburst encounter.

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.

A DOE-funded study is underway to determine the optimum refinery processing schemes for producing transportation fuels that will meet CAAA regulations from direct and indirect coal liquids. The study consists of three major parts: pilot plant testing of critical upgrading processes, linear programming analysis of different processing schemes, and engine emission testing of final products. Currently, fractions of a direct coal liquid produced form bituminous coal are being tested in sequence of pilot plant upgrading processes. This work is discussed in a separate paper. The linear programming model, which is the subject of this paper, has been completed for themore » petroleum refinery and is being modified to handle coal liquids based on the pilot plant test results. Preliminary coal liquid evaluation studies indicate that, if a refinery expansion scenario is adopted, then the marginal value of the coal liquid (over the base petroleum crude) is $3-4/bbl.« less

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.

Wing, David J.; Adams, Richard J.; Barmore, Bryan E.; Moses, Donald

2001-01-01

This paper presents initial findings of a research study designed to provide insight into the issue of intent information exchange in constrained en-route air-traffic operations and its effect on pilot decision making and flight performance. The piloted simulation was conducted in the Air Traffic Operations Laboratory at the NASA Langley Research Center. Two operational modes for autonomous operations were compared under conditions of low and high operational complexity. The tactical mode was characterized primarily by the use of state information for conflict detection and resolution and an open-loop means for the pilot to meet operational constraints. The strategic mode involved the combined use of state and intent information, provided the pilot an additional level of alerting, and allowed a closed-loop approach to meeting operational constraints. Operational constraints included separation assurance, schedule adherence, airspace hazard avoidance, flight efficiency, and passenger comfort. Potential operational benefits of both modes are illustrated through several scenario case studies. Subjective pilot ratings and comments comparing the tactical and strategic modes are presented.

A flight simulation system with graphics and software on Silicon Graphics computer workstations has been installed in the Flight Vehicle Design Laboratory at Tuskegee University. The system has F-15E flight simulation software from NASA Dryden which uses the graphics of SGI flight simulation demos. On the system, thus installed, a study of pilot induced oscillations is planned for future work. Preliminary research is conducted by obtaining two sets of straight level flights with pilot in the loop. In one set of flights no additional delay is used between the stick input and the appearance of airplane response on the computer monitor. In another set of flights, a 500 ms additional delay is used. The flight data is analyzed to find cross correlations between deflections of control surfaces and response of the airplane. The pilot dynamics features depicted from cross correlations of straight level flights are discussed in this report. The correlations presented here will serve as reference material for the corresponding correlations in a future study of pitch attitude tracking tasks involving pilot induced oscillations.

A predominant research focus in the free flight community has been on the type of information required on the flight deck to enable pilots to "autonomously" maintain separation from other aircraft. At issue are the relative utility and requirement for information exchange between aircraft regarding the current "state" and/or the "intent" of each aircraft. This paper presents the experimental design and some initial findings of an experimental research study designed to provide insight into the issue of intent information exchange in constrained en-route operations and its effect on pilot decision making and flight performance. Two operational modes for autonomous operations were compared in a piloted simulation. The tactical mode was characterized primarily by the use of state information for conflict detection and resolution and an open-loop means for the pilot to meet operational constraints. The strategic mode involved the combined use of state and intent information, provided the pilot an additional level of alerting, and allowed a closed-loop approach to meeting operational constraints. Potential operational benefits of both modes are illustrated through several scenario case studies. Subjective data results are presented that generally indicate pilot consensus in favor of the strategic mode.

Ten Years toward Equity: Preliminary Results from a Follow-Up Case Study of Academic Computing Culture

2017-01-01

Just over 10 years ago, we conducted a culture study of the Computer Science Department at the flagship University of Illinois at Urbana-Champaign, one of the top five computing departments in the country. The study found that while the department placed an emphasis on research, it did so in a way that, in conjunction with a lack of communication and transparency, devalued teaching and mentoring, and negatively impacted the professional development, education, and sense of belonging of the students. As one part of a multi-phase case study spanning over a decade, this manuscript presents preliminary findings from our latest work at the university. We detail early comparisons between data gathered at the Department of Computer Science at the University of Illinois at Urbana-Champaign in 2005 and our most recent pilot case study, a follow-up research project completed in 2016. Though we have not yet completed the full data collection, we find it worthwhile to reflect on the pilot case study data we have collected thus far. Our data reveals improvements in the perceptions of undergraduate teaching quality and undergraduate peer mentoring networks. However, we also found evidence of continuing feelings of isolation, incidents of bias, policy opacity, and uneven policy implementation that are areas of concern, particularly with respect to historically underrepresented groups. We discuss these preliminary follow-up findings, offer research and methodological reflections, and share next steps for applied research that aims to create positive cultural change in computing.

This study sought to assess the tolerability of intravenously administered psilocybin in healthy, hallucinogen-experienced volunteers in a mock-magnetic resonance imaging environment as a preliminary stage to a controlled investigation using functional magnetic resonance imaging to explore the effects of psilocybin on cerebral blood flow and activity. The present pilot study demonstrated that up to 2 mg of psilocybin delivered as a slow intravenous injection produces short-lived but typical drug effects that are psychologically and physiologically well tolerated. With appropriate care, this study supports the viability of functional magnetic resonance imaging work with psilocybin.

The aim of this preliminary study was to investigate whether religious practice can modify quality of life (QoL) in BC patients during chemotherapy. QoL and religion practice questionnaire (RPQ) scores were evaluated in a sample of BC patients in different moments. Before chemotherapy initiation, women with lower physical and social functional scores displayed higher RPQ scores. On the other hand, low RPQ patients worsened some QoL scores over time. Body image acceptance was positively correlated with religious practice and specifically praying activity. This preliminary study suggests the importance of religion in coping with cancer chemotherapy.

Despite the increasing prevalence of mental health disorders in university students, few receive needed evidence-based treatment. The purpose of this study was to assess the feasibility and preliminary effects of a seven-session online cognitive-behavioral skill-building intervention (i.e., COPE, Creating Opportunities for Personal Empowerment) versus a comparison group on their anxiety, depressive symptoms, and grade performance. A randomized controlled pilot study was conducted from September 2012 to May 2013 with 121 college freshmen enrolled in a required one credit survey course. Although there were no significant differences in anxiety and depressive symptoms between the groups, only COPE students with an elevated level of anxiety at baseline had a significant decline in symptoms. Grade point average was higher in COPE versus comparison students. Evaluations indicated that COPE was a positive experience for students. COPE is a promising brief intervention that can be integrated effectively into a required freshman course. © 2015 Wiley Periodicals, Inc.

The effects of interactive music therapy on hospitalized children with cancer: a pilot study.

Barrera, Maru E; Rykov, Mary H; Doyle, Sandra L

2002-01-01

The use of music therapy with children in health settings has been documented, but its effectiveness has not yet been well established. This pilot study is a preliminary exploration of the effectiveness of interactive music therapy in reducing anxiety and increasing the comfort of hospitalized children with cancer. Pre- and post-music therapy measures were obtained from children (N = 65) and parents. The measures consisted of children's ratings of mood using schematic faces, parental ratings of the child's play performance, and satisfaction questionnaires completed by parents, children and staff. There was a significant improvement in children's ratings of their feelings from pre- to post-music therapy. Parents perceived an improved play performance after music therapy in pre-schoolers and adolescents but not in school-aged children. Qualitative analyses of children's and parents' comments suggested a positive impact of music therapy on the child's well-being. These preliminary findings are encouraging and suggest beneficial effects of interactive music therapy with hospitalized pediatric hematology/oncology patients. In future studies replicating these findings should be conducted in a randomized control trial. Copyright 2002 John Wiley & Sons, Ltd.

Terrain Portrayal for Head-Down Displays Experiment

NASA Technical Reports Server (NTRS)

Hughes, Monica F.; Takallu, M. A.

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.

Between 40-65% of multiple sclerosis patients experience cognitive deficits, with processing speed and working memory most commonly affected. This pilot study investigated the effect of computerized cognitive training focused on improving processing speed and working memory. Participants were randomized into either an active or a sham training group and engaged in six weeks of training. The active training group improved on a measure of processing speed and attention following cognitive training, and data trended toward significance on measures of other domains. Results provide preliminary evidence that cognitive training with multiple sclerosis patients may produce moderate improvement in select areas of cognitive functioning.

2015-03-01

Functional opto-acoustic (OA) imaging was fused with gray-scale ultrasound acquired using a specialized duplex handheld probe. Feasibility Study findings indicated the potential to more accurately characterize breast masses for cancer than conventional diagnostic ultrasound (CDU). The Feasibility Study included OA imagery of 74 breast masses that were collected using the investigational Imagio® breast imaging system. Superior specificity and equal sensitivity to CDU was demonstrated, suggesting that OA fusion imaging may potentially obviate the need for negative biopsies without missing cancers in a certain percentage of breast masses. Preliminary results from a 100 subject Pilot Study are also discussed. A larger Pivotal Study (n=2,097 subjects) is underway to confirm the Feasibility Study and Pilot Study findings.

Simulation investigation of the effect of the NASA Ames 80-by 120-foot wind tunnel exhaust flow on light aircraft operating in the Moffett field trafffic pattern

Streeter, Barry G.

1986-01-01

A preliminary study of the exhaust flow from the Ames Research Center 80 by 120 Foot Wind Tunnel indicated that the flow might pose a hazard to low-flying light aircraft operating in the Moffett Field traffic pattern. A more extensive evaluation of the potential hazard was undertaken using a fixed-base, piloted simulation of a light, twin-engine, general-aviation aircraft. The simulated aircraft was flown through a model of the wind tunnel exhaust by pilots of varying experience levels to develop a data base of aircraft and pilot reactions. It is shown that a light aircraft would be subjected to a severe disturbance which, depending upon entry condition and pilot reaction, could result in a low-altitude stall or cause damage to the aircraft tail structure.

Evans, Emory T.; Young, Steven D.; Daniels, Tammi S.; Myer, Robert R.

2014-01-01

Electronic Flight Bags (EFB) are increasingly integral to flight deck information management. A piloted simulation study was conducted at NASA Langley Research Center, one aspect of which was to evaluate the usability and acceptability of EFBs for viewing and managing Notices to Airmen (NOTAMs) and data linked aeronautical information services (AIS) and meteorological information (MET). The study simulated approaches and landings at Memphis International Airport (KMEM) using various flight scenarios and weather conditions. Ten two-pilot commercial airline crews participated, utilizing the Cockpit Motion Facility's Research Flight Deck (CMF/RFD) simulator. Each crew completed approximately two dozen flights over a two day period. Two EFBs were installed, one for each pilot. Study data were collected in the form of questionnaire/interview responses, audio/video recordings, oculometer recordings, and aircraft/system state data. Preliminary usability results are reported primarily based on pilot interviews and responses to questions focused on ease of learning, ease of use, usefulness, satisfaction, and acceptability. Analysis of the data from the other objective measures (e.g., oculometer) is ongoing and will be reported in a future publication. This paper covers how the EFB functionality was set up for the study; the NOTAM, AIS/MET data link, and weather messages that were presented; questionnaire results; selected pilot observations; and conclusions.

Young men who have sex with men are at high risk for HIV, and most new HIV infections occur in serious relationships. This pilot study assessed the feasibility, acceptability and preliminary efficacy of the 2GETHER couples-based HIV prevention and relationship education intervention for young same-sex male couples. We enrolled 57 young male couples (N = 114) into a four-session hybrid group and individual intervention. We assessed acceptability via post-session surveys and exit interviews, and we examined preliminary efficacy at a two week posttest. The vast majority of participants (93%) reported exclusively positive impressions of 2GETHER, and all components received high mean ratings. We observed decreases in HIV risk behavior, increases in information, motivation and behavioral skills related to HIV prevention, and improvement in relationship investment between pretest and posttest. Integrating relationship education and sexual health programming may be an effective way to reduce HIV transmissions in young male couples.

2014-08-06

A pilot study was carried out to determine individual differences in perceived loneliness using diffusion tensor imaging. To the best of our knowledge, this is the first preliminary diffusion tensor imaging evidence that the ventral attention network, generally activated by attentional reorienting, was also related to loneliness. Image reconstruction results indicated significantly decreased fractional anisotropy of white matter fibers and that associated nodes of the ventral attention network are highly correlated with increased loneliness ratings. By providing evidence on the structural level, our findings suggested that attention-reorienting capabilities play an important role in shaping an individual's loneliness.

2008-01-01

Heavy drinking young adults often have limited motivation to change their drinking behavior. Adding pharmacotherapy to brief counseling is a novel approach to treating this population. A small open-label pilot study was conducted to assess the feasibility of offering eight weeks of daily and targeted (i.e., taken as needed in anticipation of drinking) naltrexone with BASICS (brief motivational) counseling to heavy drinking young adults; to assess the tolerability of the medication in this population and to obtain preliminary efficacy data. The sample (N = 14) showed strong adherence to study appointments and medication taking, supporting the feasibility of this approach. Overall, the medication was well-tolerated. Significant reductions from baseline were observed in drinks per drinking day and in percent heavy drinking days and these gains were maintained one month after treatment ended. A significant decrease in alcohol-related consequences was also observed. Findings from this small pilot study suggest that naltrexone in combination with BASICS represents a promising strategy to reduce heavy drinking among young adults. PMID:18502591

2017-03-01

Thyroid cancer is one of the most prevalent cancers. About 3-8% of the people in the United States have thyroid nodules, and 5-15% of these nodules are malignant. Fine-needle aspiration biopsy (FNAB) is a standard procedure to diagnose malignity of nodules. However, about 10-20% of FNABs produce indeterminable results, which leads to repeat biopsies and unnecessary surgical operations. We have explored photoacoustic (PA) imaging as a new method to identify cancerous nodules. In a pilot study to test its feasibility, we recruited patients with thyroid nodules (currently 36 cases with 21 malignant and 15 benign nodules), acquired in vivo PA and ultrasound (US) images of the nodules in real time using a recently-developed clinical PA/US imaging system, and analyzed the acquired data offline. The preliminary results show that malignant and benign nodules could be differentiated by utilizing their PA amplitudes at different excitation wavelengths. This is the first in vivo PA analysis of thyroid nodules. Although a larger-scale study is needed for statistical significance, the preliminary results show the good potential of PA imaging as a non-invasive tool for triaging thyroid cancer.

The aim of this pilot study was to investigate feasibility and preliminary efficacy of an intensive, manual-based behavioral feeding intervention for children with chronic food refusal and dependence on enteral feeding or oral nutritional formula supplementation. Twenty children ages 13 to 72 months (12 boys and 8 girls) meeting criteria for avoidant/restrictive food intake disorder were randomly assigned to receive treatment for 5 consecutive days in a day treatment program (n = 10) or waitlist (n = 10). A team of trained therapists implemented treatment under the guidance of a multidisciplinary team. Parent training was delivered to support generalization of treatment gains. We tracked parental attrition and attendance, as well as therapist fidelity. Primary outcome measures were bite acceptance, disruptions, and grams consumed during meals. Caregivers reported high satisfaction and acceptability of the intervention. Three participants (1 intervention; 2 waitlist) dropped out of the study before endpoint. Of the expected 140 treatment meals for the intervention group, 137 (97.8%) were actually attended. The intervention group showed significantly greater improvements (P < 0.05) on all primary outcome measures (d = 1.03-2.11) compared with waitlist (d = -1.13-0.24). A 1-month follow-up suggested stability in treatment gains. Results from this pilot study corroborate evidence from single-subject and nonrandomized studies on the positive effects of behavioral intervention. Findings support the feasibility and preliminary efficacy of this manual-based approach to intervention. These results warrant a large-scale randomized trial to test the safety and efficacy of this intervention.

Solar Power Satellite (SPS) pilot beam and communication link subsystem investigation study, phase 1. [ionospheric propagation, radio frequency interference, and microwave transmission

NASA Technical Reports Server (NTRS)

1979-01-01

A preliminary engineering model of ionospheric interactions with the pilot beam was established and used to demonstrate that the dual frequency baseline pilot beam system might not be viable in the presence of an unstable transmission path. Alternate approaches to remove this difficulty are described. Although ionospheric fluctuations will not significantly degrade beam pointing or raise the sidelobe levels, they will reduce transmission efficiency by upwards of 25%. Mitigating strategies to substantially reduce this effect are proposed. Based on the Klystron noise spectrum, the pilot beam transmitter power was determined as a function of frequency offset from the power beam carrier frequency. The RFI from the pilot beam, on the ground and at geosynchronous orbit is shown. Noise levels on the earth's surface due to the SPS are presented as a function of frequency and the number of SPS systems. Analysis of the communication subsystem indicates that a standard telemetry line of 1.544 MB/s would satisfy both voice and data link requirements. Additional links would be required for TV and radio transmissions.

Because Latinas experience a high prevalence of type 2 diabetes and its complications, there is an urgent need to reach them with interventions that promote healthful lifestyles. This article illustrates a sequential approach that took an effective multiple-risk-factor behavior-change program and adapted it for Latinas with type 2 diabetes. Adaptation stages include (a) information gathering from literature and focus groups, (b) preliminary adaptation design, and (c) preliminary adaptation test. In this third stage, a pilot study finds that participants were highly satisfied with the intervention and showed improvement across diverse outcomes. Key implications for applications include the importance of a model for guiding cultural adaptations, and the value of procedures for obtaining continuous feedback from staff and participants during the preliminary adaptation test.

2018-02-01

The purpose of this pilot quasi-experimental study was to examine the feasibility and preliminary efficacy of using Facebook in a 10-week lifestyle intervention with Head Start caregiver-preschooler dyads to improve healthy behaviors and reduce body mass index. Sixty-nine dyads participated with 39 in the intervention group. Average preschooler attendance rate for the Head Start center-based program was 77%, and caregiver participation rate was 87%. About 94% of the caregivers were satisfied with the program, and 97% would recommend the program to others and/or participate again. The intervention decreased preschoolers' body mass index z score (Cohen's d = -.30) and screen time ( d = -.21), and increased their fruit and vegetable intake ( d = .40) and moderate-to-vigorous physical activity ( d = .42). The intervention increased caregivers' fruit and vegetable intake ( d = .40). The intervention is feasible, and preliminary efficacy is encouraging, but further investigation using a rigorous study design is warranted.

A Pilot Study of a Distress Tolerance Treatment for Opiate Dependent Patients Initiating Buprenorphine: Rationale, Methodology, and Outcomes

PubMed Central

Brown, Richard A.; Bloom, Erika Litvin; Hecht, Jacki; Moitra, Ethan; Herman, Debra S.; Stein, Michael D.

2016-01-01

Buprenorphine, an opioid that is a long-acting partial opiate agonist, is an efficacious treatment for opiate dependence that is growing in popularity. Nevertheless, evidence suggests that many patients will lapse within the first week of treatment, and that lapses are often associated with withdrawal-related or emotional distress. Recent research suggests that individuals’ reactions to this distress may represent an important treatment target. In the current study, we describe the development and outcomes from a preliminary pilot evaluation (N = 5) of a novel distress tolerance treatment for individuals initiating buprenorphine. This treatment incorporates exposure-based and acceptance-based treatment approaches that we have previously applied to the treatment of tobacco dependence. Results from this pilot study establish the feasibility and acceptability of this approach. We are now conducting a randomized controlled trial of this treatment that we hope will yield clinically significant findings and offer clinicians an efficacious behavioral treatment to complement the effects of buprenorphine.

Matto, Holly C; Miller, Keith; Spera, Christopher

2005-08-01

A newly developed instrument that assesses a client's orientation to addiction or recovery communities using social context referents was pilot tested with a sample of 103 adults seeking treatment for substance abuse at outpatient and residential treatment facilities on the East Coast. Preliminary findings show promising subscale reliabilities, and suggest that drug- and recovery-related social identities are related to drug-use severity and drug-use concern; and drug-related attitudinal congruence between the treatment-seeker and family and treatment-seeker and other significant persons are related to intention to make behavioral changes in reducing substance abuse.

Identification of Human Factors in Unmanned Aviation Via Pilot Incident Reports

NASA Technical Reports Server (NTRS)

Hobbs, Alan; Cardoza, Colleen; Null, Cynthia

2015-01-01

There is a need for incident data relevant to the operation of civilian unmanned aircraft systems (UAS) in the National Air Space (NAS). Currently, very limited incident and accident data are available from military sources, and the tightly-restricted civilian UAS industry has produced very few incident reports that could shed light on design issues relevant to human factors. An exploratory study is being conducted to examine the feasibility of collecting voluntary critical incident reports from UAS pilots, and using the information to identify areas where human factors guidelines will be of assistance. Experienced UAS pilots are participating in small focus groups in which they are prompted to describe critical incidents that either reveal a system flaw, or highlight a case where the human operator contributed to system resilience or mission success. The de-identified incidents are being analyzed to identify contributing factors, with a focus on design issues that either hindered or assisted the pilot in dealing with the incident. Preliminary findings will be described.

Single-Lever Power Control for General Aviation Aircraft Promises Improved Efficiency and Simplified Pilot Controls

NASA Technical Reports Server (NTRS)

Musgrave, Jeffrey L.

1997-01-01

General aviation research is leading to major advances in internal combustion engine control systems for single-engine, single-pilot aircraft. These advances promise to increase engine performance and fuel efficiency while substantially reducing pilot workload and increasing flight safety. One such advance is a single-lever power control (SLPC) system, a welcome departure from older, less user-friendly, multilever engine control systems. The benefits of using single-lever power controls for general aviation aircraft are improved flight safety through advanced engine diagnostics, simplified powerplant operations, increased time between overhauls, and cost-effective technology (extends fuel burn and reduces overhaul costs). The single-lever concept has proven to be so effective in preliminary studies that general aviation manufacturers are making plans to retrofit current aircraft with the technology and are incorporating it in designs for future aircraft.

Estimation of Hydraulic Parameters and Aquifer Properties for a Managed Aquifer Recharge Pilot Study in The Lower Mississippi River Basin

NASA Astrophysics Data System (ADS)

Ozeren, Y.; Rigby, J.; Holt, R. M.

2017-12-01

Mississippi River Valley Alluvial Aquifer (MRVAA) is the major irrigation water resource in the in the lower Mississippi River basin. MRVAA has been significantly depleted in the last two decades due to excessive pumping. A wide range of measures to ensure sustainable groundwater supply in the region is currently under investigation. One of the possible solution under consideration is to use Managed Aquifer Recharge (MAR) by artificial recharge. The proposed artificial recharge technique in this study is to collect water through bank filtration, transfer water via pipeline to the critically low groundwater areas by a set of injection wells. A pilot study in the area is underway to investigate the possibility of artificial recharge in the area. As part of this study, a pumping test was carried out on an existing irrigation well along banks of Tallahatchie River near Money, MS. Geophysical surveys were also carried out in the pilot study area. Hydraulic response of the observation wells was used to determine stream bed conductance and aquifer parameters. The collected hydraulic parameters and aquifer properties will provide inputs for small-scale, high-resolution engineering model for abstraction-injection hydraulics along river. Here, preliminary results of the pilot study is presented.

The present study reviews the delivery of a pilot curriculum-mentorship-based peer vocational support workers training in a Hong Kong public psychiatric hospital. The present paper reports (1) on the development of a peer vocational support workers training - Job Buddies Training Program (JBTP) in Hong Kong; and (2) preliminary findings from both quantitative and qualitative perspectives. The curriculum consists of 15-session coursework, 8-session storytelling workshop and 50-hour practicum to provide Supported Employment Peer Service (SEPS) under the mentorship of occupational therapists. Six trainees were assessed using three psychosocial assessments and qualitative methods. Compared to the baseline, the Job Buddies (JB) trainees showed an increase in awareness of their own recovery progress, occupational competence and problem-solving skills at the end of the training. Their perceived level of self-stigma was also lessened. In post-training evaluation, all Job Buddies trainees said they perceived positive personal growth and discovered their own strengths. They also appreciated the help from their mentors and gained mutual support from other trainees and from exposure with various mini-projects in the training. This pilot study provides an example of incorporating peer support and manualized training into existing work rehabilitation service for our JB trainees. Further studies on the effectiveness of service provided by peer support workers and for development on the potential use of peer support workers in other clinical and rehabilitation settings with larger subjects will be fruitful.

This paper aims to describe 'Cognitive Existential Couple Therapy' (CECT), a novel couples-based intervention for men with early stage prostate cancer (PCa) and their partners, and to report preliminary findings from a pilot study that investigated the acceptability and feasibility of the intervention and the measures to be used in a subsequent randomised controlled trial. A manualised CECT programme was delivered to 12 couples facing a diagnosis of PCa within the previous 12 months by psychiatrists and clinical psychologists. Participants completed measures of psychological distress, marital function and coping pattern before and after CECT. Semi-structured interviews were conducted with nine couples shortly after the completion of CECT. The application of CECT was both feasible and acceptable as indicated by favourable participant compliance (10 of the 12 couples attended all six designated sessions), completion of measures before and after CECT and participation in semi-structured interviews by nine couples. Preliminary results included reduced levels of avoidance and hyperarousal after the programme, with this effect stronger in partners than in patients. Interviews demonstrated that couples valued the therapist's contribution to their overall care. Previous research suggests that a couple-focused psychological intervention is desirable in the context of early stage PCa. This pilot study has established that CECT is acceptable, feasible and valued by couples facing a recent PCa diagnosis and demonstrates a potential for reduced psychological distress following CECT. A randomised controlled trial is currently being undertaken to validate the efficacy of this novel approach. Copyright © 2011 John Wiley & Sons, Ltd.

The goal of this preliminary pilot study was to examine differences in cognitive function between adolescents with chronic pain to pain-free adolescents. All participants completed baseline assessments of pain, school absences, depression, anxiety, and sleep habits. Standardized neurocognitive tests were used to examine cognitive function with a focus on working memory and attention. Recruitment from the chronic pain clinic resulted in a female sample of 13 individuals (largely reflective of the clinical population). Pain-free age-matched and sex-matched individuals (n=12) were therefore also recruited as controls. Individuals with chronic pain had significantly lower working memory scores than controls. Differences were found between groups on the most difficult selective attention task and not on tests of sustained attention, divided attention, or attentional switching. In a stepwise regression with baseline characteristics entered in the first step, pain accounted for approximately 15% of the variance in working memory and medication score counted for 49% of the variance. This pilot study is the first study to examine differences in working memory and attention between participants with chronic pain and pain-free adolescents. Our findings suggest that chronic pain may negatively affect adolescents' working memory function and highlights the risk for cognitive difficulties and problems with educational progression in addition to negative health and social effects associated with chronic pain. The study provides a starting point for more research and has the potential to direct better identification and treatment of these cognitive deficits.

"Lost in a shopping mall" -- a breach of professional ethics.

Crook, Lynn S; Dean, Martha C

1999-01-01

The "lost in a shopping mall" study has been cited to support claims that psychotherapists can implant memories of false autobiographical information of childhood trauma in their patients. The mall study originated in 1991 as 5 pilot experiments involving 3 children and 2 adult participants. The University of Washington Human Subjects Committee granted approval for the mall study on August 10, 1992. The preliminary results with the 5 pilot subjects were announced 4 days laters. An analysis of the mall study shows that beyond the external misrepresentions, internal scientific methodological errors cast doubt on the validity of the claims that have been attributed to the mall study within scholarly and legal arenas. The minimal involvement -- or, in some cases, negative impact -- of collegial consultation, acadmic supervision, and peer review throughout the evolution of the mall study are reviewed.

Enhanced oil recovery (EOR) is a proven method for increasing oil production in many oil fields in the world. Huge oil remaining in the reservoir after primary and secondary recovery stage are the main reason for developing EOR methods. Approximately of 49.50 billion barrels oil as a candidate for EOR activities in Indonesia. This present study focuses on the chemical EOR activities involved surfactant and polymer. This research based on pertinent information from various resources such as journal papers, conference papers, and report from the government. Based on this information, this paper explain in detail the progress of each project and it shows the potential oil field employ chemical EOR in the near future. Generally, the EOR activities can be categorized into two phases such as preliminary study phase and field implementation phase. In the preliminary study, the activities simply involve experimental and/or simulation works. Following the preliminary is the field implementation phase which can be categorized into three phases such as field trial, pilot project, and full-scale. In fact, several activities have been conducted by Lemigas (government oil and gas research center), Institut Teknologi Bandung, Institut Pertanian Bogor. These activities focused on laboratory and simulation work. Those institutions have been developing the chemical formula collaborating with oil companies for applying the EOR method in their oil fields. Currently, status of chemical EOR activities include 5 oil fields under pilot project and 12 oil fields under field trial. There are 7 oil fields applying surfactant, 4 oil fields by alkaline-surfactant-polymer (ASP), 2 oil fields by polymer, 1 oil field by surfactant polymer (SP), and 1 oil field by caustic. According to this information, we will have insight knowledge about the EOR current activities, the main issues, future activities on chemical EOR in Indonesia. Moreover, this study can became the preliminary information for researchers who interested conducting further research and development on the chemical EOR activities in the near future.

With high rates of trauma among HIV-positive men who have sex with men (MSM) who use methamphetamine, this preliminary pilot study examined the associations between experiential avoidance, trauma symptoms, and management of a chronic illness. Among a small sample of HIV-positive, methamphetamine-using MSM in a California Bay Area County, greater reported experiential avoidance was significantly related to greater reported trauma and symptoms of traumatic stress. Furthermore, greater reported experiential avoidance was significantly related to reduced self-efficacy of illness management and more frequent methamphetamine use. Although further research is needed, these data suggest that addressing issues of experiential avoidance and trauma could affect behavioral choices and treatment outcomes in this high-risk population.

Macroalgae for CO 2 Capture and Renewable Energy - A Pilot Project

Wiley, Kristine

2011-01-31

The objective of this project was to demonstrate, at a pilot scale, the beneficial use of carbon dioxide (CO 2) through a technology designed to capture CO 2 from fossil-fuel fired power plant stack gas, generating macroalgae and converting the macroalgae at high efficiency to renewable methane that can be utilized in the power plant or introduced into a natural gas pipeline. The proposed pilot plant would demonstrate the cost-effectiveness and CO 2/ NO x flue-gas removal efficiency of an innovative algal scrubber technology where seaweeds are grown out of water on specially-designed supporting structures contained within greenhouses where themore » plants are constantly bathed by recycled nutrient sprays enriched by flue gas constituents. The work described in this document addresses Phase 1 of the project only. The scope of work for Phase 1 includes the completion of a preliminary design package; the collection of additional experimental data to support the preliminary and detailed design for a pilot scale utilization of CO 2 to cultivate macroalage and to process that algae to produce methane; and a technological and economic analysis to evaluate the potential of the system. Selection criteria for macroalgae that could survive the elevated temperatures and potential periodic desiccation of near desert project sites were identified. Samples of the selected macroalgae species were obtained and then subjected to anaerobic digestion to determine conversions and potential methane yields. A Process Design Package (PDP) was assembled that included process design, process flow diagram, material balance, instrumentation, and equipment list, sizes, and cost for the Phase 2 pilot plant. Preliminary economic assessments were performed under the various assumptions made, which are purposely conservative. Based on the results, additional development work should be conducted to delineate the areas for improving efficiency, reducing contingencies, and reducing overall costs.« less

In recent decades, the term student housing has been highlighted as a body of knowledge in housing studies. In providing better quality of life, student housing evolved into a critical agenda in developing higher education learning. This research paper aims to discuss on a pilot study examining student housing preferences among university and college students should they reside off-campus. The research aims at identifying the attributes of off-campus student housing preferences to give a significant input for the development of an off-campus student housing preferences conceptual framework. This research is a cross-sectional study in which survey participants are currently-enrolled students throughout the period of survey. During this pilot study, questionnaires were distributed among university students in Shah Alam, Selangor in Malaysia. A total of 86 survey questionnaires were collected, consisting of questions reflecting students' background, Likert scale questions to specify their preferences, and open-ended questions. This preliminary pilot result shows that the 46 variables student housing preferences have a good reliability and validity. The outcomes from this research provide insight into students' preferences on how off-campus housing should be developed. Since Selangor is divided into various districts with a plethora of different local contexts including different university campuses, there is a need for further study to avoid generalization.

This article describes the acceptability and preliminary behavioral outcomes of a pilot randomized control trial of a web-based indoor tanning intervention for young adult women. The intervention targets indoor tanning users' perceptions of the benefits and value of tanning and addresses the role of body image-related constructs in indoor tanning. Participants were 186 young adult women who reported indoor tanning at least once in the past 12 months. The study design was a 2-arm randomized controlled trial with pre- and postintervention assessments and random assignment to an intervention or control condition. Intervention acceptability was assessed by obtaining participants' evaluation of the intervention. Regression analyses were used to test for intervention condition differences in preliminary behavioral outcomes measured at 6 weeks postintervention. Participants provided favorable evaluations of the intervention on several dimensions and a highly positive overall rating. Intervention participants were more likely to report abstaining from indoor tanning and indicated a lower likelihood of using indoor tanning in the future compared with control participants on the postintervention assessment. No differences were found for sunburns. The results of this pilot randomized controlled trial provide evidence that the indoor tanning intervention is acceptable to participants and may encourage cessation of indoor tanning behavior. The findings provide preliminary support for an indoor tanning intervention that engages tanners to challenge their beliefs about the benefits of indoor tanning. The use of a web-based indoor tanning intervention is unique and provides strong potential for dissemination. (PsycINFO Database Record (c) 2015 APA, all rights reserved).

Incorporating Data Link Messaging into a Multi-function Display for General Aviation Aircraft

Adams, Catherine A.; Murdoch, Jennifer L.

2006-01-01

One objective of the Small Aircraft Transportation System (SATS) Project is to increase the capacity and utilization of small non-towered, non-radar equipped airports by transferring traffic management activities to an automated system and separation responsibilities to general aviation (GA) pilots. This paper describes the development of a research multi-function display (MFD) to support the interaction between pilots and an automated Airport Management Module (AMM). Preliminary results of simulation and flight tests indicate that adding the responsibility of monitoring other traffic for self-separation does not increase pilots subjective workload levels. Pilots preferred using the enhanced MFD to execute flight procedures, reporting improved situation awareness over conventional instrument flight rules (IFR) procedures.

Absence of successful transition to post-detoxification treatment leads to high rates of relapse among detoxified heroin users. The present study evaluated a pilot buprenorphine treatment program (BTP). Heroin dependent individuals were inducted onto buprenorphine/naloxone in detox, maintained while transitioning through an intensive inpatient program (IIP), and gradually tapered off medication over 5 months of outpatient (OP) treatment. Compared to programmatic indicators of treatment engagement in the year prior to BTP implementation, referrals from detox to IIP, entry into and completion of IIP and subsequent OP, and days in OP treatment increased substantially. BTP completers, compared to non-completers, viewed abstinence as more difficult and as requiring more assistance to achieve, were less likely to be current cocaine and alcohol users or to have relapsed during the course of treatment. Although preliminary and in need of replication, initial adjunctive use of buprenorphine in an abstinence-based continuum of care may improve post-detoxification treatment entry, engagement, and completion.

There are few HIV risk reduction interventions to meet the unique needs of women who experience intimate partner violence (IPV). This pilot study tested the feasibility, safety, and preliminary effects of an integrated IPV-sexual risk reduction intervention for abused women. Fifty-five women were randomized to the supporting positive and healthy relationships (SUPPORT) intervention (n = 27) or to a control group (n = 28). Assessments were conducted pre- and post-intervention and at 3-month follow-up. Post-intervention, SUPPORT participants showed a significant decrease in frequency of unprotected sex and an increase in safer sex communications with steady and other sexual partners. Compared to the control group, SUPPORT participants reported a higher number of safer sex conversations with their steady partner at the 3-month follow-up, and fewer episodes of IPV at both assessments in comparison to baseline. They showed improvements in sexual relationship power at both follow-ups and in several hypothesized antecedents of HIV-risk behavior. These encouraging preliminary findings suggest the need for a larger clinical trial.

The objective of this study was to develop and pilot test a chronic pain empowerment and self-management platform, derived from acceptance and commitment therapy, in a pain specialty setting. A controlled, sequential, nonrandomized study design was used to accommodate intervention development and to test the efficacy of the PainTracker Self-Manager (PTSM) intervention (Web-based educational modules and outcome tracking combined with tailored patient coaching sessions and provider guidance). Generalized estimating equations evaluated changes over time (baseline, 3 months, 6 months) in pain self-efficacy (primary outcome), chronic pain acceptance (activity engagement and pain willingness), perceived efficacy in patient-provider interactions, pain intensity and interference, and overall satisfaction with pain treatment (secondary outcomes) between intervention (n = 48) and usual care control groups (n = 51). The full study sample (N = 99) showed greater improvements over time (significant Group × Time interactions) in pain self-efficacy and satisfaction with pain treatment. Among study completers (n = 82), greater improvement in activity engagement as well as pain intensity and interference were also observed. These preliminary findings support the efficacy of the PTSM intervention in a pain specialty setting. Further research is needed to refine and expand the PTSM intervention and to test it in a randomized trial in primary care settings. We developed a Web-based patient empowerment platform that combined acceptance and commitment therapy-based educational modules and tailored coaching sessions with longitudinal tracking of treatments and patient-reported outcomes, named PTSM. Pilot controlled trial results provide preliminary support for its efficacy in improving pain self-efficacy, activity engagement, pain intensity and interference, and satisfaction with pain treatment.

1987-01-01

A piloted simulation study was conducted to determine the permissible time delay in the flight control system of a 10-percent statically unstable transport airplane during cruise flight conditions. The math model used for the simulation was a derivative Lockheed L-1011 wide-body jet transport. Data were collected and analyzed from a total of 137 cruising flights in both calm- and turbulent-air conditions. Results of this piloted simulation study verify previous findings that show present military specifications for allowable control-system time delay may be too stringent when applied to transport-size airplanes. Also, the degree of handling-qualities degradation due to time delay is shown to be strongly dependent on the source of the time delay in an advanced flight control system. Maximum allowable time delay for each source of time delay in the control system, in addition to a less stringent overall maximum level of time delay, should be considered for large aircraft. Preliminary results also suggest that adverse effects of control-system time delay may be at least partially offset by variations in control gearing. It is recommended that the data base include different airplane baselines, control systems, and piloting tasks with many pilots participating, so that a reasonable set of limits for control-system time delay can be established to replace the military specification limits currently being used.

A pilot study was conducted to assess correspondence among measures of program characteristics (opportunities and intervention strategies) and youth experiences in a range of activity settings in a residential immersive life skills (RILS) program. Opportunities and intervention strategies were assessed in 18 activity settings in the 21-day program. On two occasions each, four youth completed a measure of experiences and took part in onsite interviews. There was good convergence between observed program opportunities and the use of socially-mediated, teaching/learning, and non-intrusive strategies. Youth experiences of social interaction, choice, and personal growth were further informed by interview information. There was substantial convergence between program characteristics and youth experiences, indicating the program was provided and experienced as intended. This pilot study indicated the fidelity of the program and the feasibility of using the measures in a future study. The preliminary findings suggest that RILS programs may provide a favorable environment for developmental experiences concerning social interaction, autonomy, and personal growth.

A pilot aid -- a kinesthetic-tactual compensatory display -- for assisting novice pilots in various inflight situations has undergone preliminary inflight testing. The efficacy of this display, as compared with two types of visual displays, was evaluated in both a highly structured approach-and-landing task and a less structured test involving tight turns about a point. In both situations, the displayed quantity was the deviation (alpha sub 0 - alpha) in angle at attack from a desired value alpha sub 0. In the former, the performance with the tactual display was comparable with that obtained using a visual display of (alpha sub 0 - alpha), while in the later, substantial improvements (reduced tracking error (55%), decreased maximum altitude variations (67%), and decreased speed variations (43%)), were obtained using the tactual display. It appears that such a display offers considerable potential for inflight use.

The main objective of this pilot study was to gather preliminary information about how telomere length (TL) varies in relation to exposure to polycyclic aromatic hydrocarbons (PAHs) in children living in a highly polluted city. We conducted a cross-sectional study of children living in Fresno, California (n = 14). Subjects with and without asthma were selected based on their annual average PAH level in the 12-months prior to their blood draw. We measured relative telomere length from peripheral blood mononuclear cells (PBMC). We found an inverse linear relationship between average PAH level and TL (R = 0.69), as well as between age and TL (R = 0.21). Asthmatics had shorter mean telomere length than non-asthmatics (TLasthmatic = 1.13, TLnon-asthmatic = 1.29). These preliminary findings suggest that exposure to ambient PAH may play a role in telomere shortening.Become familiar with previous evidence suggesting that telomere length may be a biomarker of air pollution-induced cytotoxicity.Summarize the new findings on the association between polycyclic aromatic hydrocarbon (PAH) exposure and telomere length in adolescents, including those with asthma.Discuss the implications for recommendations and policies to mitigate the health and respiratory effects of traffic-related air pollution.

Neurofibromatosis type 1 (NF1) is an autosomal dominant genetic disorder affecting about 1 in 3,500 individuals. Chronic pain is commonly reported among individuals with NF1 and plexiform neurofibroma tumors (PNs). Acceptance and Commitment Therapy (ACT), an empirically supported method for addressing chronic pain, helps individuals re-focus on valued relationships and activities. This pilot study investigated the feasibility and preliminary efficacy of a brief ACT workshop in the NF1 population. Eligible participants included adolescents and young adults (AYA; 12-21 years) with NF1 and chronic pain that interfered with daily functioning and their parents. Patients and parents completed baseline measures of pain interference, pain intensity, functional disability, pain acceptance, depression, and anxiety. Then, AYA and parents participated separately in a 2-day small-group ACT workshop. A telephone booster session occurred 1 month post-intervention. Three-month post-treatment measures were completed by mail. Ten adolescents (4 males; M age = 16.9 years) and seven parents provided baseline and 3-month data. Mean satisfaction with the study was moderate to high (3.9 for patients and 4.6 for parents on a 1-5 scales). Patients and parents reported significant declines in patients' pain interference at 3 months post-treatment. Patient-reported pain intensity significantly declined from baseline to 3 months. Parents reported marginally greater acceptance of their child's pain. No changes emerged in functional ability or mood. Preliminary findings suggest that a brief ACT group intervention is feasible and may help AYA with NF1 and PNs cope with their chronic pain, although larger randomized studies are needed to confirm treatment efficacy. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

Cognitive assessment with virtual reality (VR) may have superior ecological validity for older adults compared to traditional pencil-and-paper cognitive assessment. However, few studies have reported the development of VR tasks. The aim of this study was to present the development, feasibility, content validity, and preliminary evidence of construct validity of an ecological task of cognitive assessment for older adults in VR (ECO-VR). The tasks were prepared based on theoretical and clinical backgrounds. We had 29 non-expert judges identify virtual visual stimuli and three-dimensional scenarios, and five expert judges assisted with content analysis and developing instructions. Finally, six older persons participated in three pilot studies and thirty older persons participated in the preliminary study to identify construct validity evidence. Data were analyzed by descriptive statistics and partial correlation. Target stimuli and three-dimensional scenarios were judged adequate and the content analysis demonstrated that ECO-VR evaluates temporo-spatial orientation, memory, language and executive functioning. We made significant changes to the instructions after the pilot studies to increase comprehensibility and reduce the completion time. The total score of ECO-VR was positively correlated mainly with performance in executive function (r = .172, p < .05) and memory tests (r = .488, p ≤ .01). The ECO-VR demonstrated feasibility for cognitive assessment in older adults, as well as content and construct validity evidences.

National Land Imaging Requirements (NLIR) Pilot Project summary report: summary of moderate resolution imaging user requirements

Vadnais, Carolyn; Stensaas, Gregory

2014-01-01

Under the National Land Imaging Requirements (NLIR) Project, the U.S. Geological Survey (USGS) is developing a functional capability to obtain, characterize, manage, maintain and prioritize all Earth observing (EO) land remote sensing user requirements. The goal is a better understanding of community needs that can be supported with land remote sensing resources, and a means to match needs with appropriate solutions in an effective and efficient way. The NLIR Project is composed of two components. The first component is focused on the development of the Earth Observation Requirements Evaluation System (EORES) to capture, store and analyze user requirements, whereas, the second component is the mechanism and processes to elicit and document the user requirements that will populate the EORES. To develop the second component, the requirements elicitation methodology was exercised and refined through a pilot project conducted from June to September 2013. The pilot project focused specifically on applications and user requirements for moderate resolution imagery (5–120 meter resolution) as the test case for requirements development. The purpose of this summary report is to provide a high-level overview of the requirements elicitation process that was exercised through the pilot project and an early analysis of the moderate resolution imaging user requirements acquired to date to support ongoing USGS sustainable land imaging study needs. The pilot project engaged a limited set of Federal Government users from the operational and research communities and therefore the information captured represents only a subset of all land imaging user requirements. However, based on a comparison of results, trends, and analysis, the pilot captured a strong baseline of typical applications areas and user needs for moderate resolution imagery. Because these results are preliminary and represent only a sample of users and application areas, the information from this report should only be used to indicate general user needs for the applications covered. Users of the information are cautioned that use of specific numeric results may be inappropriate without additional research. Any information used or cited from this report should specifically be cited as preliminary findings.

Cognitive behavioral therapy for insomnia (CBTI) has proven efficacy, yet 32%-89% of patients fail to consistently follow recommendations. This pilot study examines adherence to CBTI in breast cancer survivors with insomnia. There was a significant decline in adherence to prescribed rise time, and total time in bed, but no change in adherence to prescribed bedtime during six weekly sessions. Factors associated with higher adherence included lower fatigue and higher baseline motivation. Higher adherence was associated with worse subjective sleep quality at the beginning of CBTI and fewer nocturnal awakenings at the end of treatment. Results provide preliminary evidence supporting the impact of adherence on sleep outcomes such as fewer nocturnal awakenings. Attention to adherence as part of CBTI may yield greater sleep improvements.

With the introduction of digital datalink communications into the Air Traffic Control (ATC) system, there is concern over the potential loss of situational awareness by flight crews due to the reduction in the 'Party Line Information' (PLI). This information is available to the pilot by overhearing communications between ATC and other aircraft. A survey was distributed to determine current PLI use by several pilot operational groups, experience levels and geographic regions. The survey identified numerous important elements. PLI was rated the highest for operations near or on approach to the airport. Several significant variations were found between pilots from different operational groups and experience levels. Traffic and weather information were the most frequently cited as information required to obtain global situation awareness.

1990-01-01

Although pilot-controller communication is central to aviation safety, this area of aviation human factors has not been extensively researched. Most research has focused on what kinds of communication problems occur. A more complete picture of communication problems requires understanding how communication usually works in routine operations. A sample of routine pilot-controller communication in the TRACON environment is described. After describing several dimensions of routine communication, three kinds of communication problems are treated: inaccuracies such as incorrect readbacks, procedural deviations such as missing callsigns and readbacks, and nonroutine transactions where pilot and controller must deal with misunderstandings or other communication problems. Preliminary results suggest these problems are not frequent events in daily operations. However, analysis of the problems that do occur suggest some factors that may cause them.

This study examined functional connectivity of the default mode network (DMN) and examined brain-behavior relationships in a pilot cohort of children with chronic mild to moderate traumatic brain injury (TBI). Compared to uninjured peers, children with TBI demonstrated less anti-correlated functional connectivity between DMN and right Brodmann Area 40 (BA 40). In children with TBI, more anomalous less anti-correlated) connectivity between DMN and right BA 40 was linked to poorer performance on response inhibition tasks. Collectively, these preliminary findings suggest that functional connectivity between DMN and BA 40 may relate to longterm functional outcomes in chronic pediatric TBI.

To pilot test the newly developed multidisciplinary group rehabilitation programme Visually Impaired elderly Persons Participating (VIPP). A single group pretest-posttest design pilot study included 29 visually impaired persons (≥ 55 years). The intervention (20 weekly meetings) consisted of four components (practical training; education, social interaction, counselling and training of problem-solving skills; individual and group goal setting; home-based exercise programme). Participation was assessed with the Utrecht Scale for Evaluation of Rehabilitation-Participation (USER-P) and the Impact on Participation and Autonomy (IPA) questionnaire at baseline, immediately and 6 months after the intervention. At scale level, no statistical significant changes over time were found whereas the effect size indicated small effects for restrictions and satisfaction with participation, and a medium effect for autonomy outdoors. At item level, improvements tended to occur in frequency of housekeeping, in restrictions in housekeeping and outdoor activities and in satisfaction with the partner relationship. Satisfaction with leisure indoors and autonomy regarding using leisure time tended to increase as well. The tentative conclusion of this small-scale pilot study is that the VIPP programme modestly benefits perceived restrictions in participation, satisfaction with participation and autonomy outdoors of the visually impaired elderly. These preliminary findings warrant further investigation.

The Agricultural Model Intercomparison and Improvement Project (AgMIP): Progress and Preliminary Results

2011-12-01

The Agricultural Model Intercomparison and Improvement Project (AgMIP) is a distributed climate-scenario simulation exercise for historical model intercomparison and future climate change conditions with participation of multiple crop and agricultural trade modeling groups around the world. The goals of AgMIP are to improve substantially the characterization of risk of hunger and world food security due to climate change and to enhance adaptation capacity in both developing and developed countries. Recent progress and the current status of AgMIP will be presented, highlighting three areas of activity: preliminary results from crop pilot studies, outcomes from regional workshops, and emerging scientific challenges. AgMIP crop modeling efforts are being led by pilot studies, which have been established for wheat, maize, rice, and sugarcane. These crop-specific initiatives have proven instrumental in testing and contributing to AgMIP protocols, as well as creating preliminary results for aggregation and input to agricultural trade models. Regional workshops are being held to encourage collaborations and set research activities in motion for key agricultural areas. The first of these workshops was hosted by Embrapa and UNICAMP and held in Campinas, Brazil. Outcomes from this meeting have informed crop modeling research activities within South America, AgMIP protocols, and future regional workshops. Several scientific challenges have emerged and are currently being addressed by AgMIP researchers. Areas of particular interest include geospatial weather generation, ensemble methods for climate scenarios and crop models, spatial aggregation of field-scale yields to regional and global production, and characterization of future changes in climate variability.

The Role of Empowerment in a School-Based Community Service Program with Inner-City, Minority Youth

Gullan, Rebecca L.; Power, Thomas J.; Leff, Stephen S.

2014-01-01

Despite considerable fiscal and structural support for youth service programs, research has not demonstrated consistent outcomes across participants or programs, suggesting the need to identify critical program processes. The present study addresses this need through preliminary examination of the role of program empowerment in promoting positive identity development in inner-city, African American youth participating in a pilot school-based service program. Results suggest that participants who experienced the program as empowering experienced increases in self-efficacy, sense of civic responsibility, and ethnic identity, over and above general engagement and enjoyment of the program. Preliminary exploration of differences based on participant gender suggests that some results may be stronger and more consistent for males than females. These findings provide preliminary support for the importance of theoretically grounded program processes in producing positive outcomes for youth service participants. PMID:25104875

Stress predicts brain changes in children: a pilot longitudinal study on youth stress, posttraumatic stress disorder, and the hippocampus.

Does stress damage the brain? Studies of adults with posttraumatic stress disorder have demonstrated smaller hippocampal volumes when compared with the volumes of adults with no posttraumatic stress disorder. Studies of children with posttraumatic stress disorder have not replicated the smaller hippocampal findings in adults, which suggests that smaller hippocampal volume may be caused by neurodevelopmental experiences with stress. Animal research has demonstrated that the glucocorticoids secreted during stress can be neurotoxic to the hippocampus, but this has not been empirically demonstrated in human samples. We hypothesized that cortisol volumes would predict hippocampal volume reduction in patients with posttraumatic symptoms. We report data from a pilot longitudinal study of children (n = 15) with history of maltreatment who underwent clinical evaluation for posttraumatic stress disorder, cortisol, and neuroimaging. Posttraumatic stress disorder symptoms and cortisol at baseline predicted hippocampal reduction over an ensuing 12- to 18-month interval. Results from this pilot study suggest that stress is associated with hippocampal reduction in children with posttraumatic stress disorder symptoms and provide preliminary human evidence that stress may indeed damage the hippocampus. Additional studies seem to be warranted.

Formerly incarcerated adults are impoverished, have high rates of substance use disorders, and have long histories of imprisonment. This article describes the development of a peer mentoring program for formerly incarcerated adults and the pilot study designed to evaluate it. The research team, which included formerly incarcerated adults and academic researchers, developed the peer mentoring program to support formerly incarcerated adults' transition to the community after prison. The purposes of the pilot evaluation study were to (1) assess the feasibility of implementing a peer-based intervention for recently released men developed using a community-based participatory research (CBPR) approach; (2) establish preliminary data on the program's impact on coping, self-esteem, abstinence self-efficacy, social support, and participation in 12-step meetings; and (3) establish a CBPR team of formerly incarcerated adults and academic researchers to develop, implement, and test interventions for this population. This pilot evaluation study employed a mixed-methods approach with a single group pretest/posttest design with 20 men on parole released from prison within the last 30 days. Quantitative findings showed significant improvement on two abstinence self-efficacy subscales, negative affect and habitual craving. Qualitative findings revealed the relevance and acceptance of peer mentoring for this population. This study demonstrated the feasibility and import of involving formerly incarcerated adults in the design, implementation, and testing of interventions intended to support their reintegration efforts.

Trelagliptin, an oral DPP-4 inhibitor, which is administered once per week and characterized by a long half-life in blood. The effects of trelagliptin on vascular endothelial functions have not been clarified to date. The objective of the present study was to examine the effects of trelagliptin on vascular endothelial functions in patients with type 2 diabetes mellitus (DM) using flow-mediated dilatation (FMD), adiponectin, and asymmetric dimethylarginine (ADMA) as evaluation indicators. This study was a preliminary single-arm prospective pilot study. The subjects of this study were type 2 DM patients aged 20-74 years, who visited our outpatient department. The patients were treated with trelagliptin, and their FMD, adiponectin, and ADMA levels were measured at baseline and at 12 weeks after initial treatment to determine the changes during the study period. A total of 27 patients, excluding three dropouts, were included in the population for analysis. Trelagliptin treatment showed no significant changes in FMD (2.42 ± 2.7% at baseline vs. 2.66 ± 3.8% post-treatment, P = 0.785) and ADMA (0.41 ± 0.0 µg/mL at baseline vs. 0.40 ± 0.0 µg/mL post-treatment, P = 0.402). Trelagliptin treatment resulted in a significant increase of serum adiponectin level (7.72 ± 6.9 µg/mL at baseline vs. 8.82 ± 8.3 µg/mL post-treatment, P < 0.002). In this pilot study, trelagliptin treatment showed no significant changes in FMD. On the other hand, it was believed that trelagliptin treatment may increase serum adiponectin level.

The cost of diapering an infant can place a significant financial strain on families living in poverty. Partnerships between diaper banks and home visiting programs for young families may offer an innovative solution to expanding the reach and impact of diaper banks in low-income communities. The purpose of this pilot study was to uncover preliminary information about the functions of diaper distribution through home visiting programs, and to inform future research and policy questions regarding diaper distribution to families in need. In this descriptive qualitative pilot study, semi-structured interviews were conducted with 6 home visitors from Minding the Baby ® (MTB), a home visiting intervention for young parents. MTB clinicians routinely distribute diapers in partnership with The Diaper Bank in Connecticut. We used directed content analysis to code and analyze interview transcripts. These preliminary findings indicate that partnerships between home visiting programs and diaper banks may benefit families by improving diaper access, reducing stigma, and fostering trusting relationships with home visitors. Home visiting program benefits including engagement or re-engagement with families may need to be balanced with potential effects on clinical and therapeutic relationships. Recommendations for next steps in research and related policy questions are discussed. © 2017 Wiley Periodicals, Inc.

Psychosocial factors, including job demands and poor resources, have been linked to stress, health problems, and negative job attitudes. However, worksite based interventions and programs targeting psychosocial factors may change employees' perceptions of their work climate and work attitudes. This pilot study describes a newly developed worksite based participatory organizational intervention program that was tested in the social service sector. It is evaluated using participants' perceptions of the intervention to investigate its acceptability as a feature of feasibility and its short-term effects on work climate factors (job demands and resources) and work-related attitudes. Forty employees of a Swedish social service unit provided self-reports before, during, and after the intervention. As for effects, quantitative role overload and social support decreased while turnover intention increased. Responses to an open-ended question showed that participants considered the intervention program valuable for addressing issues relating to the psychosocial work climate. Although the findings are preliminary, it was possible to carry out this worksite based participatory organizational program in this particular setting. Also, the preliminary findings underscore the challenges associated with designing and implementing this type of intervention program, thus adding to the methodological discussion on implementation and evaluation.

Abstract Objective To conduct a preliminary validation of the Satisfaction With Decision (SWD) scale with depressed primary care patients. Design  Cross‐sectional observational pilot study using a postal survey. Setting and participants  Depressed primary care patients (n = 97) who recently had made a new decision about antidepressant medication use completed surveys regarding their treatment decisions. Main variables  Measures included patient‐reported satisfaction with decision, decisional conflict, knowledge about depression and treatment, decision involvement, pain and health status, antidepressant medication efficacy, and satisfaction with health services. Results  The SWD scale had good internal consistency reliability (α = 0.85). Evidence for construct validity was confirmed via a hypothesized pattern of relationships between the SWD scale and other measures. Decision satisfaction was associated with several issues of relevance for designing patient‐centred decision support interventions: (1) knowledge about depression and treatment; (2) involvement in health‐related decisions; and (3) aiding evaluation of trade‐offs among pros and cons of treatment. Conclusions  The results of this pilot study show that the SWD scale appears to be a psychometrically sound and practical measure for research with this population. Additional research is needed on the theoretical nature of decision satisfaction and developing and testing patient‐centred decision support interventions for depression treatment. PMID:12752743

Trujillo, Anna C.; Gregory, Irene M.

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.

In the USA, adults of Korean descent tend to eat fewer vegetables than adults in South Korea. The present pilot study examined the feasibility of developing and implementing a faith-based intervention to improve knowledge, attitudes and intake of fruit and vegetables (F&V) for Koreans in the USA. Feasibility pilot using a cluster-randomized intervention trial design. The multicomponent intervention included motivational interviewing sessions by telephone and church-based group activities. Eleven of the largest Korean churches in Southern California. Adults (n 71) from the eleven Korean churches. Feasibility was demonstrated for the study procedures, including recruitment of churches and individual participants. Allocating time throughout the study for church collaboration and having a study church coordinator to coordinate multiple churches were crucial. Participants' attendance at church activities (89 %) and participation by pastors and fellow churchgoers exceeded expectations. Participants' use of intervention materials was high (94 % or above) and satisfaction with coaching sessions was also high (75 % or above). Having a centralized coach trained in motivational interviewing, instead of one at each church, proved practical. Pilot results are promising for F&V knowledge, attitudes and behaviours. The intervention group improved knowledge and intake of the recommended amounts of F&V, above that of the control group. This pilot suggests that Koreans in the USA can be reached through their church and that a faith-based intervention study can be implemented to increase F&V intake. Preliminary results for the intervention appear promising but further research is needed to properly evaluate its efficacy.

Re-use of pilot data and interim analysis of pivotal data in MRMC studies: a simulation study

2017-03-01

Novel medical imaging devices are often evaluated with multi-reader multi-case (MRMC) studies in which radiologists read images of patient cases for a specified clinical task (e.g., cancer detection). A pilot study is often used to measure the effect size and variance parameters that are necessary for sizing a pivotal study (including sizing readers, non-diseased and diseased cases). Due to the practical difficulty of collecting patient cases or recruiting clinical readers, some investigators attempt to include the pilot data as part of their pivotal study. In other situations, some investigators attempt to perform an interim analysis of their pivotal study data based upon which the sample sizes may be re-estimated. Re-use of the pilot data or interim analyses of the pivotal data may inflate the type I error of the pivotal study. In this work, we use the Roe and Metz model to simulate MRMC data under the null hypothesis (i.e., two devices have equal diagnostic performance) and investigate the type I error rate for several practical designs involving re-use of pilot data or interim analysis of pivotal data. Our preliminary simulation results indicate that, under the simulation conditions we investigated, the inflation of type I error is none or only marginal for some design strategies (e.g., re-use of patient data without re-using readers, and size re-estimation without using the effect-size estimated in the interim analysis). Upon further verifications, these are potentially useful design methods in that they may help make a study less burdensome and have a better chance to succeed without substantial loss of the statistical rigor.

The goal of the Full Mission Sim was to examine the effects of different command and control interfaces on UAS pilots' ability to respond to ATC commands and traffic advisories. Results suggest that higher levels of automation (i.e., waypoint-to-waypoint control interfaces) lead to longer initial response times and longer edit times. The findings demonstrate the importance of providing pilots with interfaces that facilitate their ability to get back "in the loop."

A program of flying qualities experiments as part of the Orbiter Experiments Program (OEX) is defined. Phase 1, published as CR-170391, reviewed flying qualities criteria and shuttle data. The review of applicable experimental and shuttle data to further define the OEX plan is continued. An unconventional feature of this approach is the use of pilot strategy model identification to relate flight and simulator results. Instrumentation, software, and data analysis techniques for pilot model measurements are examined. The relationship between shuttle characteristics and superaugmented aircraft is established. STS flights 1 through 4 are reviewed from the point of view of flying qualities. A preliminary plan for a coordinated program of inflight and simulator research is presented.

An Activated Carbon Treatment System (ACTS) was developed for sewage treatment and is being applied to a one-million gallon per day sewage treatment pilot plant in Orange County California. Activities reported include pyrolysis and activation of carbon-sewage sludge, and activated carbon treatment of sewage to meet ocean discharge standards. The ACTS Sewage treatment operations include carbon-sewage treatment, primary and secondary clarifiers, gravity (multi-media) filter, filter press dewatering, flash drying of carbon-sewage filter cake, and sludge pyrolysis and activation. Tests were conducted on a laboratory scale, 10,000 gallon per day demonstration plant and pilot test equipment. Preliminary economic studies are favorable to the ACTS process relative to activated sludge treatment for a 175,000,000 gallon per day sewage treatment plant.

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.

One objective of the Small Aircraft Transportation System (SATS) Project is to increase the capacity and utilization of small non-towered, non-radar equipped airports by transferring traffic management activities to an automated system and separation responsibilities to general aviation (GA) pilots. This paper describes the development of a research multi-function display (MFD) to support the interaction between pilots and an automated Airport Management Module (AMM). Preliminary results of simulation and flight tests indicate that adding the responsibility of monitoring other traffic for self-separation does not increase pilots' subjective workload levels. Pilots preferred using the enhanced MFD to execute flight procedures, reporting improved situation awareness (SA) over conventional instrument flight rules (IFR) procedures.

A successful pilot-scale process for biodiesel production from microbial oil (Biooil) produced by Rhodosporidium toruloides DEBB 5533 is presented. Using fed-batch strategy (1000L working volume), a lipid productivity of 0.44g/L.h was obtained using a low-cost medium composed by sugarcane juice and urea. The microbial oil was used for biodiesel production and its performance was evaluated in diesel engine tests, showing very good performance, especially for the blend B20 SCO, when operating at 2500rpm with lower pollutant emissions (CO 2 - 220% less; CO - 7-fold less; NO X 50% less and no detectable HC emissions (<0.11ppm)) when compared with the blends of standard biofuel from soybean oil. A preliminary analysis showed that microbial biodiesel is economically competitive (US$ 0.76/L) when compared to the vegetable biodiesel (US$ 0.81/L). Besides, the yield of biodiesel from microbial oil is higher (4172L/ha of cultivated sugarcane) that represents 6.3-fold the yield of standard biodiesel (661L/ha of cultivated soybean).

Previous studies have consistently reported age-related changes in cognitive abilities and brain structure. Previous studies also suggest compensatory roles for specialized training, skill, and years of education in the age-related decline of cognitive function. The Stanford/VA Aviation Study examines the influence of specialized training and skill level (expertise) on age-related changes in cognition and brain structure. This preliminary report examines the effect of aviation expertise, years of education, age, and brain size on flight simulator performance in pilots aged 45–68 years. Fifty-one pilots were studied with structural magnetic resonance imaging, flight simulator, and processing speed tasks. There were significant main effects of age (p < .01) and expertise (p < .01), but not of whole brain size (p > .1) or education (p > .1), on flight simulator performance. However, even though age and brain size were correlated (r = −0.41), age differences in flight simulator performance were not explained by brain size. Both aviation expertise and education were involved in an interaction with brain size in predicting flight simulator performance (p < .05). These results point to the importance of examining measures of expertise and their interactions to assess age-related cognitive changes. PMID:20193103

We hypothesized that virtual family meetings in the intensive care unit with conference calling or Skype videoconferencing would result in increased family member satisfaction and more efficient decision making. This is a prospective, nonblinded, nonrandomized pilot study. A 6-question survey was completed by family members after family meetings, some of which used conference calling or Skype by choice. Overall, 29 (33%) of the completed surveys came from audiovisual family meetings vs 59 (67%) from control meetings. The survey data were analyzed using hierarchical linear modeling, which did not find any significant group differences between satisfaction with the audiovisual meetings vs controls. There was no association between the audiovisual intervention and withdrawal of care (P = .682) or overall hospital length of stay (z = 0.885, P = .376). Although we do not report benefit from an audiovisual intervention, these results are preliminary and heavily influenced by notable limitations to the study. Given that the intervention was feasible in this pilot study, audiovisual and social media intervention strategies warrant additional investigation given their unique ability to facilitate communication among family members in the intensive care unit.

2011-01-01

The determination of the virus retention capabilities of UF units during operation is essential for the operators of drinking water treatment facilities in order to guarantee an efficient and stable removal of viruses through time. In previous studies, an effective method (MS2-phage challenge tests) was developed by the Water Research Center of Veolia Environnement for the measurement of the virus retention rates (Log Removal Rate, LRV) of commercially available hollow fiber membranes at lab scale. In the present work, the protocol for monitoring membrane performance was transferred from lab scale to pilot scale. Membrane performances were evaluated during pilot trial and compared to the results obtained at lab scale with fibers taken from the pilot plant modules. PFU culture method was compared to RT-PCR method for the calculation of LRV in both cases. Preliminary tests at lab scale showed that both methods can be used interchangeably. For tests conducted on virgin membrane, a good consistency was observed between lab and pilot scale results with the two analytical methods used. This work intends to show that a reliable determination of the membranes performances based on RT-PCR analytical method can be achieved during the operation of the UF units.

Development of ADOCS controllers and control laws. Volume 2: Literature review and preliminary analysis

1985-01-01

The Advanced Cockpit Controls/Advanced Flight Control System (ACC/AFCS) study was conducted by the Boeing Vertol Company as part of the Army's Advanced Digital/Optical Control System (ADOCS) program. Specifically, the ACC/AFCS investigation was aimed at developing the flight control laws for the ADOCS demonstrator aircraft which will provide satisfactory handling qualities for an attack helicopter mission. The three major elements of design considered are as follows: Pilot's integrated Side-Stick Controller (SSC) -- Number of axes controlled; force/displacement characteristics; ergonomic design. Stability and Control Augmentation System (SCAS)--Digital flight control laws for the various mission phases; SCAS mode switching logic. Pilot's Displays--For night/adverse weather conditions, the dynamics of the superimposed symbology presented to the pilot in a format similar to the Advanced Attack Helicopter (AAH) Pilot Night Vision System (PNVS) for each mission phase as a function of ACAS characteristics; display mode switching logic. Findings from the literature review and the analysis and synthesis of desired control laws are reported in Volume 2. Conclusions drawn from pilot rating data and commentary were used to formulate recommendations for the ADOCS demonstrator flight control system design. The ACC/AFCS simulation data also provide an extensive data base to aid the development of advanced flight control system design for future V/STOL aircraft.

The pilot study aimed at examining the neural glutamatergic activity in autism. Seven adolescent males (mean age: 14 ± 1.8; age range: 12-17 years) with intact intellectual capacity (mean IQ: 108 ± 14.26; IQ range: 85-127) suffering from autistic disorder and an equal number of age- and sex-matched healthy controls underwent a two-dimensional magnetic resonance spectroscopy scan at 4T. Results indicated significantly high glutamate (Glu) levels in the anterior cingulate cortex of autistic disorder versus control subjects (paired t test p = 0.01) and a trend for lower Glu in the right medial temporal lobe, which was not statistically different between the groups (paired t test p = 0.06). These preliminary findings support the glutamatergic dysregulation hypothesis in autism and need to be replicated in a larger sample.

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.

This document provides a preliminary assessment and summary of the command, control, and communications (C(sup 3)) loading requirements of a generic future high-altitude, long-endurance unmanned aircraft (UA) operating at in the National Airspace System. Two principal types of C(sup 3) traffic are considered in our analysis: communications links providing air traffic services (ATS) to the UA and its human pilot, and the command and control data links enabling the pilot to operate the UA remotely. we have quantified the loading requirements of both types of traffic for two different assumed levels of UA autonomy. Our results indicate that the potential use of UA-borne relays for the ATS links, and the degree of autonomy exercised by the UA during the departure and arrival phases of its flight, will be among the key drivers of C(sup 3) loading and bandwidth requirements.

A preliminary assessment was made of the adequacy of a simple head up display (HUD) for providing vertical guidance for flying noise abatement and standard visual approaches in a jet transport. The HUD featured gyro-stabilized approach angle scales which display the angle of declination to any point on the ground and a horizontal flight path bar which aids the pilot in his control of the aircraft flight path angle. Thirty-three standard and noise abatement approaches were flown in a Boeing 747 aircraft equipped with a head up display. The HUD was also simulated in a research simulator. The simulator was used to familiarize the pilots with the display and to determine the most suitable way to use the HUD for making high capture noise abatement approaches. Preliminary flight and simulator data are presented and problem areas that require further investigation are identified.

Specialist practitioner' in surgical dentistry: preliminary report on a pilot scheme at East Surrey Hospital, Redhill, UK.

PubMed

Parker, J K

1999-12-01

This continuing pilot scheme was designed to assess whether minor oral operations could be done by a 'specialist practitioner' in surgical dentistry in hospital. The preliminary results indicate that patients benefit from the improved facilities and expertise that are available in the hospital, that the provision of treatment within the hospital is at a sufficiently 'local' level to meet their requirements, and that this increased quality of service can be provided at no greater cost to the NHS than treating them in a dental surgery. A large amount of the dentoalveolar surgery done (such as removal of third molars) is regarded as routine, but 'routine' is often mistakenly thought to mean 'simple' or 'easy'. Dentoalveolar surgery not only demands the highest quality of care and expertise but it also requires the necessary immediate support if medical or surgical complications arise.

A kinesthetic tactual display may be effectively used as a control aid per previous flight tests. Angle of attack information would be continuously presented to a pilot, via this display, during critical operational phases where stalls are probable. A two phase plan for evaluating this concept is presented. A first development phase would encompass: (1) display fabrication for a conventional control yoke; (2) its installation, together with other necessary instrumentation, in an experimental aircraft; and (3) preliminary flight testing by experienced pilots.

Probiotics act as a unique approach to maintaining oral health by supplementing the endogenous oral bacteria with additional naturally occurring beneficial microbes to provide defense against pathogens harmful to teeth and gingiva. The aim of this pilot study was to clinically evaluate the effects of probiotics on plaque accumulation and gingival inflammation in subjects with fixed orthodontics. The pilot study was comprised of 15 healthy patients, aged 11 to 18 years, undergoing fixed orthodontic treatment. Patients used an all-natural, dissolving lozenge containing six proprietary probiotic strains (Dentaq® Oral and ENT Health Probiotic Complex)for 28 days. Gingival Index (GI) according to Löe-Silness and Plaque Index (PI) according to Quigley-Hein for all teeth were measured at baseline (Day Zero) and at the end of the probiotic regimen (Day 28). The mean baseline GI and PI scores within each patient decreased by 28.4% and 35.8%, respectively, by Day 28. Patients reported decreased tooth and gingival pain, decreased oral bleeding, and increased motivation to maintain proper oral hygiene over the course of the study. This pilot study provided preliminary support for the use of Dentaq Oral and ENT Health Probiotic Complex as a safe and effective natural health product for the reduction of plaque accumulation and gingival inflammation. The results demonstrate its potential therapeutic value and open the door for larger scale placebo-controlled clinical studies to verify these findings.

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.

To assess the feasibility of conducting a randomized controlled trial of an instructional and educational stroke DVD and determine the feasibility and preliminary efficacy of this intervention in a multinational context. Non-funded, pilot randomized controlled trial of intervention versus usual care. International, multicentre, community-based. Community-living adults up to three years post stroke with moderate to severe disability and their nominated informal caregivers. Intervention patients viewed and practised rehabilitation techniques demonstrated in the DVD over six weeks. Trial feasibility by number of active recruitment sites, recruitment efficiency, randomization and follow-up. Intervention feasibility by patient and caregiver impressions. Preliminary efficacy by the quality of life - 5-level EuroQol-5D (EQ-5D) health status measure, General Health Questionnaire and Centre for Epidemiological Studies-Depression at two months. In total, 14 recruitment sites were established across eight countries. Recruitment was achieved at nine (64%) sites. Over 16 months, 66 participants were recruited (mean (SD) age = 63.5 (12.47) years) and randomized to intervention ( n = 34) and control ( n = 32) groups. In total, 54 (82%) completed a follow-up assessment. Patient and/or caregiver comments about the benefits and barriers to accessing the intervention were mixed. There were no significant between-group differences in outcomes at two months ( P > 0.05). Conducting a multinational trial of a stroke DVD requires full funding. The intervention was acceptable to some patients and their caregivers, yet a generalized education approach did not fully meet their needs and/or expectations. A more individualized method may be required to meet peoples' changing needs during stroke recovery.

Depression affects 18-30 % of HIV-infected patients in Africa and is associated with greater stigma, lower antiretroviral adherence, and faster disease progression. However, the region's health system capacity to effectively identify and treat depression is limited. Task-shifting models may help address this large mental health treatment gap. Measurement-Based Care (MBC) is a task-shifting model in which a Depression Care Manager guides a non-psychiatric (e.g., HIV) provider in prescribing and managing antidepressant treatment. We adapted MBC for depressed HIV-infected patients in Cameroon and completed a pilot study to assess feasibility, safety, acceptability, and preliminary efficacy. We enrolled 55 participants; all started amitriptyline 25-50 mg daily at baseline. By 12 weeks, most remained at 50 mg daily (range 25-125 mg). Median (interquartile range) PHQ-9 depressive severity scores declined from 13 (12-16) (baseline) to 2 (0-3) (week 12); 87 % achieved depression remission (PHQ-9 <5) by 12 weeks. Intervention fidelity was high: HIV providers followed MBC recommendations at 96 % of encounters. Most divergences reflected a failure to increase dose when indicated. No serious and few bothersome side effects were reported. Most suicidality (prevalence 62 % at baseline; 8 % at 12 weeks) was either passive or low-risk. Participant satisfaction was high (100 %), and most participants (89 %) indicated willingness to pay for medications if MBC were implemented in routine care. The adapted MBC intervention demonstrated high feasibility, safety, acceptability, and preliminary efficacy in this uncontrolled pilot study. Further research should assess whether MBC could improve adherence and HIV outcomes in this setting.

To assess the feasibility, acceptability, and preliminary effectiveness of a peer-delivered and technology supported integrated medical and psychiatric self-management intervention for older adults with serious mental illness. Ten older adults with serious mental illness (i.e., schizophrenia, schizoaffective disorder, bipolar disorder, or major depressive disorder) and medical comorbidity (i.e., cardiovascular disease, obesity, diabetes, chronic obstructive pulmonary disease, hypertension, and/or high cholesterol) aged 60 years and older received the PeerTECH intervention in their homes. Three certified peer specialists were trained to deliver PeerTECH. Data were collected at baseline, one-month, and three-month. The pilot study demonstrated that a three-month, peer-delivered and technology-supported integrated medical and psychiatric self-management intervention ("PeerTECH") was experienced by peer specialists and participants as feasible and acceptable. PeerTECH was associated with statistically significant improvements in psychiatric self-management. In addition, pre/post, non-statistically significant improvements were observed in self-efficacy for managing chronic health conditions, hope, quality of life, medical self-management skills, and empowerment. This pre/post pilot study demonstrated it is possible to train peers to use technology to deliver an integrated psychiatric and medical self-management intervention in a home-based setting to older adults with serious mental illness with fidelity. These findings provide preliminary evidence that a peer-delivered and technology-supported intervention designed to improve medical and psychiatric self-management is feasible, acceptable, and is potentially associated with improvements in psychiatric self-management, self-efficacy for managing chronic health conditions, hope, quality of life, medical self-management skills, and empowerment with older adults with serious mental illness and chronic health conditions.

The widespread and devastating nature of obsessive compulsive disorder (OCD) sharply contrasts with the paucity of research involving Mexican Americans and Mexicans who suffer from this condition. This mixed-methods preliminary study was intended to provide initial data and to pilot the procedures for a larger investigation of the cultural identification, symptomatology, health concerns, coping mechanisms, and quality of life of Mexican Americans and Mexicans with OCD living in the U.S.-Mexico border region of El Paso, Texas and Ciudad Juarez, Mexico. For the sample of six participants, whose symptoms ranged from moderate to extreme, OCD was associated with marked impairment in quality of life, particularly in terms of social functioning, an area of central importance for many Mexican Americans and Mexicans. Areas of further study were identified, with the aim of developing culturally sensitive interventions to decrease health disparities involving OCD. PMID:17917689

Preliminary investigation into a seated unloading movement strategy for the lumbar spine: a pilot study.

2010-04-01

This study was a preliminary investigation into a seated unloading movement strategy for the lumbar spine using the upper extremities. With the economic burden of LBP estimated in the billions worldwide, and also with a trend towards more jobs related to sitting, a simple distraction exercise coined chair-care is presented. An attempt to objectify using stadiometry was used to measure standing height changes after 15 min of sitting and after the exercise. The results showed significant standing height gains post-exercise when compared to post-sitting and initial standing (2.4 and 2.7 mm, respectively). No significant standing height changes were seen after 15 min of sitting. It is therefore likely that this simple seated exercise creates standing height gains of the spine. Proposed mechanisms are discussed with an emphasis on spinal hydraulics and intervertebral disc nutrition. Reproducible studies are required. Copyright 2008 Elsevier Ltd. All rights reserved.

2018-05-01

In the current study, the associations between inpatient aggression and the living group climate as perceived by the adolescents admitted to a forensic psychiatric treatment unit, are investigated based on carefully registered longitudinal data. Multilevel regression analyses revealed a significant inverse relation between the number and severity of aggressive incidents and the amount of support, as well as with the possibilities of growth perceived by the adolescents. No significant associations of aggression and the perception of repression or atmosphere are found. Our study reveals preliminary evidence for the relation between the prevalence of aggressive incidents and how the adolescents perceive social contextual factors in daily forensic treatment practices. Moreover, preliminary evidence that evidence-based treatment programs and psychiatric care have an important influence on experienced possibilities for growth and support and as such prevent institutional aggression, is found.

To assess the clinical and work productivity effects of a brief intervention using telephone-administered cognitive-behavioral therapy (CBT) for clients with depressive symptoms attending an employee assistance program (EAP). Self-referred clients attending the PPC Canada EAP with clinically relevant depressive symptoms at initial assessment were offered an 8-session telephone-administered CBT program. Outcomes before and after intervention were assessed with the 9-item Personal Health Questionnaire (PHQ-9), Global Assessment of Functioning (GAF), and clinician ratings of work absence and performance impairment. Fifty clients were referred to the pilot program; 39 participated and 31 completed the telephone CBT program. Among program participants, there was significant improvement in PHQ-9 and GAF scores. There was also a significant reduction in performance impairment but not work absence. Anecdotal reports indicated high satisfaction ratings among participants. The results of this pilot study, although limited by the absence of a comparison or control group, suggest that a brief telephone-administered CBT program can improve depressive symptomatology, work productivity, and general function in depressed clients attending an EAP. Further controlled studies are needed to confirm these preliminary findings.

The Urban Ecology Institute (UEI) promotes the stewardship of healthy urban ecosystems by improving science and civic education for middle and high school youth and by working with urban communities to protect and transform natural resources. Established in 1999, UEI's field studies program engages over 1000 youth in the greater Boston area. A substantial component of this program involves water quality monitoring. We have recently adapted protocols from published leaf breakdown studies for incorporation into the UEI water quality curriculum. A 2004 pilot study of these leaf breakdown activities, conducted at four sites, compared rates of red maple breakdown to those of Norway maple, a potentially invasive urban street tree. Preliminary data from this successful pilot study suggest that leaf litter inputs from the two different tree species have varying effects on stream ecosystem function. We present this study as an example of how urban areas can be utilized for both ecological research and inclusive experiential learning through which science and mathematic knowledge can be effectively communicated.

Manned Versus Unmanned Risk and Complexity Considerations for Future Midsized X-Planes

The objective of this work was to identify and estimate complexity and risks associated with the development and testing of new low-cost medium-scale X-plane aircraft primarily focused on air transport operations. Piloting modes that were evaluated for this task were manned, remotely piloted, and unmanned flight research programs. This analysis was conducted early in the data collection period for X-plane concept vehicles before preliminary designs were complete. Over 50 different aircraft and system topics were used to evaluate the three piloting control modes. Expert group evaluations from a diverse set of pilots, engineers, and other experts at Aeronautics Research Mission Directorate centers within the National Aeronautics and Space Administration provided qualitative reasoning on the many issues surrounding the decisions regarding piloting modes. The group evaluations were numerically rated to evaluate each topic quantitatively and were used to provide independent criteria for vehicle complexity and risk. An Edwards Air Force Base instruction document was identified that emerged as a source of the effects found in our qualitative and quantitative data. The study showed that a manned aircraft was the best choice to align with test activities for transport aircraft flight research from a low-complexity and low-risk perspective. The study concluded that a manned aircraft option would minimize the risk and complexity to improve flight-test efficiency and bound the cost of the flight-test portion of the program. Several key findings and discriminators between the three modes are discussed in detail.

Haptic-Multimodal Flight Control System Update

The rapidly advancing capabilities of autonomous aircraft suggest a future where many of the responsibilities of today s pilot transition to the vehicle, transforming the pilot s job into something akin to driving a car or simply being a passenger. Notionally, this transition will reduce the specialized skills, training, and attention required of the human user while improving safety and performance. However, our experience with highly automated aircraft highlights many challenges to this transition including: lack of automation resilience; adverse human-automation interaction under stress; and the difficulty of developing certification standards and methods of compliance for complex systems performing critical functions traditionally performed by the pilot (e.g., sense and avoid vs. see and avoid). Recognizing these opportunities and realities, researchers at NASA Langley are developing a haptic-multimodal flight control (HFC) system concept that can serve as a bridge between today s state of the art aircraft that are highly automated but have little autonomy and can only be operated safely by highly trained experts (i.e., pilots) to a future in which non-experts (e.g., drivers) can safely and reliably use autonomous aircraft to perform a variety of missions. This paper reviews the motivation and theoretical basis of the HFC system, describes its current state of development, and presents results from two pilot-in-the-loop simulation studies. These preliminary studies suggest the HFC reshapes human-automation interaction in a way well-suited to revolutionary ease-of-use.

Grand rounds offer an excellent opportunity for the evaluation of medical expertise, and other competencies, such as communication and professionalism. The purpose of this study was to develop a tool that would facilitate the provision of formative feedback for grand rounds to improve learning. The resulting CanMEDS-based evaluation tool was piloted in an academic surgical department. This study employed the use of a 3-phase, qualitatively-focused, embedded mixed methods approach. In Phase 1, an intrinsic case study was conducted to identify preliminary themes. These findings were crystallized using a quantitative survey. Following interpretation of these data, a grand rounds evaluation tool was developed in Phase 2. The tool was piloted in the Phase 3 focus group. This study was piloted at an academic surgical center among members of the Department of Surgery, McMaster University, Ontario, Canada. Purposive sampling was used for this study. A total of n = 7 individuals participated in the Phase 1 interviews, and n = 24 participants completed the Phase 1 survey. Participants included a representative sample of medical students, residents, fellows, and staff. The tool was piloted among n = 19 participants. The proposed evaluation tool contains 13 Likert-scale questions and 2 open-ended questions. The tool outlines specific questions to assess grand rounds presenters within the structure of the 7 CanMEDS competency domains. "Evaluation fatigue" was identified as a major barrier in the willingness to provide effective feedback. Further, a number of factors regarding the preferred content, structure, and format of surgical grand rounds were identified. This pilot study presents a CanMEDS-specific evaluation tool that can be applied to surgical grand rounds. With the increasing adoption of competency-based medical education, comprehensive evaluation of surgical activities is required. This form provides a template for the development of competency-based evaluation tools for medical and surgical learning activities. Copyright © 2016 Association of Program Directors in Surgery.

Cockpit weather information needs

Scanlon, Charles H.

1992-01-01

The primary objective is to develop an advanced pilot weather interface for the flight deck and to measure its utilization and effectiveness in pilot reroute decision processes, weather situation awareness, and weather monitoring. Identical graphical weather displays for the dispatcher, air traffic control (ATC), and pilot crew should also enhance the dialogue capabilities for reroute decisions. By utilizing a broadcast data link for surface observations, forecasts, radar summaries, lightning strikes, and weather alerts, onboard weather computing facilities construct graphical displays, historical weather displays, color textual displays, and other tools to assist the pilot crew. Since the weather data is continually being received and stored by the airborne system, the pilot crew has instantaneous access to the latest information. This information is color coded to distinguish degrees of category for surface observations, ceiling and visibilities, and ground radar summaries. Automatic weather monitoring and pilot crew alerting is accomplished by the airborne computing facilities. When a new weather information is received, the displays are instantaneously changed to reflect the new information. Also, when a new surface or special observation for the intended destination is received, the pilot crew is informed so that information can be studied at the pilot's discretion. The pilot crew is also immediately alerted when a severe weather notice, AIRMET or SIGMET, is received. The cockpit weather display shares a multicolor eight inch cathode ray tube and overlaid touch panel with a pilot crew data link interface. Touch sensitive buttons and areas are used for pilot selection of graphical and data link displays. Time critical ATC messages are presented in a small window that overlays other displays so that immediate pilot alerting and action can be taken. Predeparture and reroute clearances are displayed on the graphical weather system so pilot review of weather along the route can be accomplished prior to pilot acceptance of the clearance. An ongoing multiphase test series is planned for testing and modifying the graphical weather system. Preliminary data shows that the nine test subjects considered the graphical presentation to be much better than their current weather information source for situation awareness, flight safety, and reroute decision making.

Cognitive-behavioural group therapy versus guided self-help for compulsive buying disorder: a preliminary study.

2013-01-01

Compulsive buying (CB) is defined as extreme preoccupation with buying/shopping and frequent buying that causes substantial negative psychological, social, occupational and financial consequences. There exists preliminary evidence that group cognitive-behavioural therapy (CBT) is effective in the treatment of CB. The present pilot study made a first attempt to compare group CBT for CB with telephone-guided self-help (GSH). Fifty-six patients were allocated randomly to one of the three conditions: (1) group CBT (n = 22); (2) GSH (n = 20); and (3) a waiting list condition (n = 14). The results indicate that face-to-face group CBT is superior not only to the waiting list condition but also to GSH. Patients who received GSH tended to have more success in overcoming CB compared with the waiting list controls. Given the sample size, the results must be considered as preliminary and further research is needed to address the topic whether GSH also could be a helpful intervention in reducing CB.

Aim: To describe the rationale and design of a pilot study evaluating the integration of pharmacogenetic (PGx) testing into pharmacist-delivered medication therapy management (MTM). Study rationale: Clinical delivery approaches of PGx testing involving pharmacists may overcome barriers of limited physician knowledge about and experience with testing. Study design: We will assess the addition of PGx testing to MTM services for cardiology patients taking three or more medications including simvastatin or clopidogrel. We will measure the impact of MTM plus PGx testing on drug/dose adjustment and clinical outcomes. Factors associated with delivery, such as time to prepare and conduct MTM and consult with physicians will be recorded. Additionally, patient interest and satisfaction will be measured. Anticipated results: We anticipate that PGx testing can be practically integrated into standard a MTM service, providing a viable delivery model for testing. Conclusion: Given the lack of evidence of an effective PGx delivery models, this study will provide preliminary evidence regarding a pharmacist-delivered approach.

Computers are used increasingly in patient-clinician consultations. There is the potential for PC use to have an effect on the communication process. The aim of this preliminary study was to investigate patient opinion regarding the use of PC-based note taking during diagnostic vestibular assessments. We gave a simple four-item questionnaire to 100 consecutive patients attending for vestibular assessment at a secondary referral level primary care trust audiology service. Written responses to two of the questionnaire items were subject to an inductive thematic analysis. The questionnaire was acceptable to patients, none refused to complete it. Dominant themes identified suggest that patients do perceive consistent positive benefits from the use of PC-based note taking. This pilot study's short survey instrument is usable and may provide insights into patients' perceptions of computer use in a clinical setting.

To facilitate effectiveness testing and dissemination of treatments to community based setting, therapist training manuals that are more “community friendly” are needed. The aim of the current project was to create revised versions of individual drug counseling (IDC) and group drug counseling (GDC) treatment manuals for cocaine dependence and to conduct a preliminary study of their effectiveness. After changing the format and context of existing drug counseling manuals to have greater ease of use in the community, draft manuals were given to 23 community-based counselors for their feedback. Final versions were then used in a pilot randomized clinical trial involving 41 cocaine dependent patients who received 3 months of either IDC + GDC or GDC alone treatment. Counselors implemented the new treatment manuals with acceptable levels of adherence and competence. Outcome results indicated that substantial change in drug use was evident, but the amount of abstinence obtained was limited. PMID:19038525

Previous studies have shown that psychosexual functioning in adolescents with autism spectrum disorder (ASD) is hampered and emphasize the need for a specialized training program tailored to their needs. Therefore, an individual training program was developed; the Tackling Teenage Training (TTT) program. The current pilot study systematically evaluated whether psychosexual knowledge increased after taking part in the TTT program, using a pre- and post-training design in 30 adolescents with ASD (77 % male, mean age = 14.80 years, mean intelligence = 96.96). Psychosexual knowledge increased significantly (pre-training total score: M = 25.74, SD = 6.20; post-training total score: M = 33.52 (SD = 2.78); F(1,29) = 65.20, p < .001). The TTT program may be useful to improve psychosexual knowledge and functioning in adolescents with ASD, yet these findings are preliminary, and a more elaborate controlled trial is needed.

The measurement of beliefs and attitudes on poverty and housing is important to researchers and social workers interested in examining the role that belief structures have on the development of policy and programs in these areas. This article reports pilot study findings of a new scale, The Poverty and Housing Scale (PHS), that measures this concept and evaluates its psychometric properties. Preliminary reliability was in the very good range. Examinations of content and face validity provided support of the instrument as a valid measure of beliefs and attitudes on poverty and housing. The factor analysis emerged a one factor, 13-item scale. Unlike other related scales, the PHS attempts to link the social factor of poverty and housing together. Theoretical and methodological strengths and weaknesses are considered and the implications for social work practice are discussed. The authors provide recommendations for additional testing of the instrument.

Research on moving evidence-based practice (EBP) intervention strategies to community service settings for children with autism spectrum disorders (ASD) is urgently needed. The current pilot study addresses this need by examining the feasibility, acceptability and preliminary outcomes of training therapists practicing in community mental health (CMH) clinics to deliver a package of EBP strategies aimed to reduce challenging behaviors in school-age children with ASD. Results indicate that CMH therapists participated in both initial and ongoing training, were able to deliver the intervention with fidelity, and perceived the intervention strategies as useful. Parents participated in almost all sessions with their children and remained in therapy when therapists delivered the intervention. Meaningful reductions in child problem behaviors occurred over 5 months providing promising support for the intervention. PMID:22102293

Airflow hazards such as turbulence, vortices, or low-level wind shear can pose a threat to landing aircraft and are especially dangerous to helicopters. Because pilots usually cannot see airflow, they may be unaware of the extent of the hazard. We have developed a prototype airflow hazard visual display for use in helicopter cockpits to alleviate this problem. We report on the results of a preliminary usability study of our airflow hazard visualization system in helicopter-shipboard operations.

A relationship between generalized anxiety disorder (GAD) and fear of falling (FOF) has long been proposed but never specifically studied. This study aimed at analyzing the relationship between FOF and GAD or anxiety symptoms, while controlling for major depressive episodes (MDE), depressive symptoms, fall risk, and sociodemographic variables. Twenty-five older adults participated in this pilot study. Assessments included the following: Anxiety Disorder Interview Schedule, Geriatric Anxiety Inventory, Geriatric Depression Scale, Falls-Efficacy Scale-International. A multidisciplinary team evaluated fall risk. FOF was significantly correlated with GAD, MDE, anxiety and depressive symptoms, and fall risk, but not with sociodemographic variables. Multiple regression analyses indicated that GAD and anxiety symptoms were significantly and independently associated with FOF. Although the results of this pilot study should be replicated with larger samples, they suggest that FOF is associated with GAD and anxiety symptoms even when considering physical factors that increase the risk of falling. Treatment of FOF in patients with GAD may present a particular challenge because of the central role of intolerance of uncertainty, which may prevent patients from regaining confidence despite the reduction of fall risk. Clinicians should screen for GAD and anxiety symptoms in patients with FOF to improve detection and treatment.

The Development and Preliminary Testing of an Instrument for Assessing Fatigue Self-management Outcomes in Patients With Advanced Cancer.

PubMed

Chan, Raymond Javan; Yates, Patsy; McCarthy, Alexandra L

Fatigue is one of the most distressing and commonly experienced symptoms in patients with advanced cancer. Although the self-management (SM) of cancer-related symptoms has received increasing attention, no research instrument assessing fatigue SM outcomes for patients with advanced cancer is available. The aim of this study was to describe the development and preliminary testing of an interviewer-administered instrument for assessing the frequency and perceived levels of effectiveness and self-efficacy associated with fatigue SM behaviors in patients with advanced cancer. The development and testing of the Self-efficacy in Managing Symptoms Scale-Fatigue Subscale for Patients With Advanced Cancer (SMSFS-A) involved a number of procedures: item generation using a comprehensive literature review and semistructured interviews, content validity evaluation using expert panel reviews, and face validity and test-retest reliability evaluation using pilot testing. Initially, 23 items (22 specific behaviors with 1 global item) were generated from the literature review and semistructured interviews. After 2 rounds of expert panel review, the final scale was reduced to 17 items (16 behaviors with 1 global item). Participants in the pilot test (n = 10) confirmed that the questions in this scale were clear and easy to understand. Bland-Altman analysis showed agreement of results over a 1-week interval. The SMSFS-A items were generated using multiple sources. This tool demonstrated preliminary validity and reliability. The SMSFS-A has the potential to be used for clinical and research purposes. Nurses can use this instrument for collecting data to inform the initiation of appropriate fatigue SM support for this population.

Cancer patients with chemotherapy-induced peripheral neuropathy (CIPN) have sensory and motor deficits leading to inappropriate proprioceptive feedback, impaired postural control, and fall risk. Balance training with computerized force platforms has been successfully used in rehabilitation of balance disturbances, but programs specifically developed for CIPN patients are lacking. This pilot study evaluated a rehabilitation protocol exclusively based on visual computer-feedback balance training (VCFBT) to improve balance in patients with CIPN. Open-label, non-randomized pilot study, 4-week intervention with pre- vs. post-treatment evaluation. Outpatients of the Rehabilitation Institute of the Salvatore Maugeri Foundation, in Genoa, Italy. Seven out-patients with clinical-instrumental diagnosis of CIPN. At admission, patients were administered the Berg Balance Scale (BBS) and underwent static-dynamic posturography using a computerized force platform to objectively quantify their balance impairment. Their performance was compared to values of a normal age-matched population. Patients then underwent 4 weeks of VCFBT (three 60-minute sessions/week). At discharge, BBS and posturography were repeated and the results compared with those at admission. A significant pre- vs. post-treatment improvement was found in balance as measured by static-dynamic posturography (P=0.004) and BBS (P<0.002). Despite caution needed for the low sample size, this pilot study has shown preliminary evidence that intensive rehabilitation, based on VCFBT can produce a significant improvement in balance outcomes. To our knowledge, this is the first report in CIPN patients of a rehabilitation program based exclusively on VCFBT.

To develop a complex intervention for community pharmacy staff to promote uptake of smoking cessation services and to increase quit rates. Following the Medical Research Council framework, we used a mixed-methods approach to develop, pilot and then refine the intervention. Phase I : We used information from qualitative studies in pharmacies, systematic literature reviews and the Capability, Opportunity, Motivation-Behaviour framework to inform design of the initial version of the intervention. Phase II : We then tested the acceptability of this intervention with smoking cessation advisers and assessed fidelity using actors who visited pharmacies posing as smokers, in a pilot study. Phase III : We reviewed the content and associated theory underpinning our intervention, taking account of the results of the earlier studies and a realist analysis of published literature. We then confirmed a logic model describing the intended operation of the intervention and used this model to refine the intervention and associated materials. Eight community pharmacies in three inner east London boroughs. 12 Stop Smoking Advisers. Two, 150 min, skills-based training sessions focused on communication and behaviour change skills with between session practice. The pilot study confirmed acceptability of the intervention and showed preliminary evidence of benefit; however, organisational barriers tended to limit effective operation. The pilot data and realist review pointed to additional use of Diffusion of Innovations Theory to seat the intervention in the wider organisational context. We have developed and refined an intervention to promote smoking cessation services in community pharmacies, which we now plan to evaluate in a randomised controlled trial.

Research findings suggest that patients severely affected by multiple sclerosis benefit from palliative care. Our objectives were to (1) implement a pilot palliative care counseling hotline for severely affected multiple sclerosis patients and their caregivers in order to connect them to palliative care, and (2) evaluate its preliminary feasibility through a pilot study. The hotline was designed in cooperation with the local state association of the German Multiple Sclerosis Society and based on a review of the literature. The initial study setting for the hotline was the broader region of the cities Cologne and Bonn in Germany. The hotline was introduced through a magazine published by the German Multiple Sclerosis Society and leaflets sent to local healthcare providers. Calls were conducted using a semistructured interview guide and documented by a standardized case report form. Measures to assess feasibility were both quantitative (e.g., number of calls) and qualitative (e.g., criteria for eligibility for palliative care). During its pilot year, the hotline received 18 calls. Some 15 callers were included in the analysis, and 10 of these 15 were deemed eligible for palliative care due to such criteria as medical characteristics, care or nursing conditions, caregiver strain, and concerns regarding death and dying. Access to palliative care services could be provided for all 10 callers. Based on our pilot feasibility study, the hotline seems to be a valuable service for patients severely affected by multiple sclerosis (MS) and their caregivers in order to gain information about and access to palliative care. It will be extended on a nationwide scale through a grant of the German Multiple Sclerosis Society. Awareness of the hotline needs to be enhanced in order to attract and support a significant number of new callers.

Pilot Non-Conformance to Alerting System Commands During Closely Spaced Parallel Approaches

NASA Technical Reports Server (NTRS)

Pritchett, Amy Ruth; Hansman, R. John; Corker, Kevin (Technical Monitor)

1997-01-01

Cockpit alerting systems monitor potentially hazardous situations, both inside and outside the aircraft. When a hazard is projected to occur, the alerting system displays alerts and/or command decisions to the pilot. However, pilots have been observed to not conform to alerting system commands by delaying their response or by not following the automatic commands exactly. This non-conformance to the automatic alerting system can reduce its benefit. Therefore, a need exists to understand the causes and effects of pilot non-conformance in order to develop automatic alerting systems whose commands the pilots are more likely to follow. These considerations were examined through flight simulator evaluations of the collision avoidance task during closely spaced parallel approaches. This task provided a useful case-study because the effects of non-conformance can be significant, given the time-critical nature of the task. A preliminary evaluation of alerting systems identified non-conformance in over 40% of the cases and a corresponding drop in collision avoidance performance. A follow-on experiment found subjects' alerting and maneuver selection criteria were consistent with different strategies than those used by automatic systems, indicating the pilot may potentially disagree with the alerting system if the pilot attempts to verify automatic alerts and commanded avoidance maneuvers. A final experiment found supporting automatic alerts with the explicit display of its underlying criteria resulted in more consistent subject reactions. In light of these experimental results, a general discussion of pilot non-conformance is provided. Contributing factors in pilot non-conformance include a lack of confidence in the automatic system and mismatches between the alerting system's commands and the pilots' own decisions based on the information available to them. The effects of non-conformance on system performance are discussed. Possible methods of reconciling mismatches are given, and design considerations for alerting systems which alleviate the problem of non-conformance are provided.

This stability augmentation system is postulated as the simplest system that meets handling qualities levels for research and technology missions flown by NASA test pilots. The airplane studied in this report is a T-39 fitted with tilting lift/cruise fan nacelles and a nose fan. The propulsion system features a shaft interconnecting the three variable pitch fans and three power plants. The mathematical modeling is based on pre-wind tunnel test estimated data. The selected stability augmentation system uses variable gains scheduled with airspeed. Failure analysis of the system illustrates the benign effect of engine failure. Airplane rate sensor failure must be solved with redundancy.

This paper describes an experimental paradigm and a set of preliminary results which demonstrate a relationship between the level of performance on a skilled man-machine control task, the skill of the operator, the level of mental difficulty induced by an additional task imposed on the basic control task, and visual scanning performance. During a constant, simulated piloting task, visual scanning of instruments was found to vary as a function of the level of difficulty of a verbal loading task. The average dwell time of each fixation on the pilot's primary instrument increased as a function of the loading. The scanning behavior was also a function of the estimated skill level of the pilots, with novices being affected by the loading task much more than experts. The results suggest that visual scanning of instruments in a controlled task may be an indicator of both workload and skill.

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.

Developmental delays and dental caries in low-income preschoolers in the USA: a pilot cross-sectional study and preliminary explanatory model

PubMed Central

2013-01-01

Background Anecdotal evidence suggests that low-income preschoolers with developmental delays are at increased risk for dental caries and poor oral health, but there are no published studies based on empirical data. The purpose of this pilot study was two-fold: to examine the relationship between developmental delays and dental caries in low-income preschoolers and to present a preliminary explanatory model on the determinants of caries for enrollees in Head Start, a U.S. school readiness program for low-income preschool-aged children. Methods Data were collected on preschoolers ages 3–5 years at two Head Start centers in Washington, USA (N = 115). The predictor variable was developmental delay status (no/yes). The outcome variable was the prevalence of decayed, missing, and filled surfaces (dmfs) on primary teeth. We used multiple variable Poisson regression models to test the hypothesis that within a population of low-income preschoolers, those with developmental delays would have increased dmfs prevalence than those without developmental delays. Results Seventeen percent of preschoolers had a developmental delay and 51.3% of preschoolers had ≥1 dmfs. Preschoolers with developmental delays had a dmfs prevalence ratio that was 1.26 times as high as preschoolers without developmental delays (95% CI: 1.01, 1.58; P < .04). Other factors associated with increased dmfs prevalence ratios included: not having a dental home (P = .01); low caregiver education (P < .001); and living in a non-fluoridated community (P < .001). Conclusions Our pilot data suggest that developmental delays among low-income preschoolers are associated with increased primary tooth dmfs. Additional research is needed to further examine this relationship. Future interventions and policies should focus on caries prevention strategies within settings like Head Start classrooms that serve low-income preschool-aged children with additional targeted home- and community-based interventions for those with developmental delays.

The activities during a four-year study by doctoral students to evolve in detail a design for a simple-to-fly, constant attitude light airplane are described. The study indicated that such aircraft could materially reduce the hazards to light airplane occupants which arise from the high pilot work load and poor visibility that occur during landing. Preliminary cost studies indicate that in volume production this system would increase the cost of the aircraft in roughly the same fashion that automatic transmission, power steering, power brakes, and cruise control increase the cost of a compact car.

Manual tracking experiments were conducted to determine the suitability of tactual displays for presenting flight-control information in multitask situations. Although tracking error scores are considerably greater than scores obtained with a continuous visual display, preliminary results indicate that inter-task interference effects are substantially less with the tactual display in situations that impose high visual scanning workloads. The single-task performance degradation found with the tactual display appears to be a result of the coding scheme rather than the use of the tactual sensory mode per se. Analysis with the state-variable pilot/vehicle model shows that reliable predictions of tracking errors can be obtained for wide-band tracking systems once the pilot-related model parameters have been adjusted to reflect the pilot-display interaction.

Objective and setting This paper describes the evaluation of a pilot situational judgement test (SJT) for selection into UK Dental Core Training (DCT). The SJT's psychometric properties, group differences based on gender and ethnicity, and candidate reactions were assessed.Methods The SJT targets four non-academic attributes important for success in DCT. Data were collected alongside live selection processes from five Health Education England local teams in the UK (N = 386). Candidates completed the pilot SJT and an evaluation questionnaire to examine their reactions to the test.Results SJT scores were relatively normally distributed and showed acceptable levels of internal reliability (α = 0.68). Difficulty level and partial correlations between scenarios and SJT total score were in the expected ranges (64.61% to 90.03% and r = 0.06 to 0.41, respectively). No group differences were found for gender, and group differences between White and BME candidates were minimal. Most candidates perceived the SJT as relevant to the target role, appropriate and fair.Conclusions This study demonstrated the potential suitability of an SJT for use in DCT selection. Future research should replicate these preliminary findings in other cohorts, and assess the predictive validity of the SJT for predicting key training and practice-based outcomes.

Objective To provide a preliminary assessment of obstetric healthcare provider opinions surrounding implementation of cell-free fetal DNA testing. Methods A 37-question pilot survey was used to address questions around the translation and use of non-invasive prenatal testing using cell-free fetal DNA. The survey was distributed and collected at a Continuing Medical Education course on obstetrics and gynecology. Results Of 62 survey respondents, 73% are female and 87% hold MD/DO degrees. Respondents generally agree that patients want prenatal diagnostic information to help make decisions about a pregnancy and that cell-free fetal DNA testing will encourage the testing of more patients for more conditions. However, there is an overall lack of knowledge or conviction about using this technology. Genetic counseling and professional society approval are deemed important to implementation whereas the possibility of direct-to-consumer testing and government regulation produce mixed responses. Respondents indicate that they are more likely to offer cell-free fetal DNA testing for chromosomal abnormalities and single-gene disorders, but are cautious with respect to determination of sex and behavioral or late-onset conditions. Conclusion Preliminary assessment indicates uncertainty among obstetric providers about the details of implementing cell-free fetal DNA testing and suggests expanded research on perspectives of this stakeholder group.

A preliminary study of containment concepts for aircraft landing on elevated STOL-ports

NASA Technical Reports Server (NTRS)

Haviland, J. K.

1971-01-01

A preliminary study of containment systems for aircraft landing on elevated STOL-ports was conducted as part of an overall study of human acceptance problems associated with STOL operations. The study included a survey and feasibility study of different concepts and a computer analysis of four arrestment systems. The principal conclusion was that a system referred to as the FAA system appears to offer the greatest promise. In this system, standard arresting gear cables are stretched across the roof-top, at roughly 100-foot intervals, but are shielded over the 100-foot-wide primary landing strip. Thus a pilot can land with an arresting hook down, but will not contact the cable unless he swerves off the landing strip, either because he has made a bad landing, or because his landing gear has failed. It was also noted that a suitable curb or guard rail should be developed. Presently available arresting gears and nylon net barriers were considered satisfactory for the overshoot problem.

Towards a genetics-based adaptive agent to support flight testing

NASA Astrophysics Data System (ADS)

Cribbs, Henry Brown, III

Although the benefits of aircraft simulation have been known since the late 1960s, simulation almost always entails interaction with a human test pilot. This "pilot-in-the-loop" simulation process provides useful evaluative information to the aircraft designer and provides a training tool to the pilot. Emulation of a pilot during the early phases of the aircraft design process might provide designers a useful evaluative tool. Machine learning might emulate a pilot in a simulated aircraft/cockpit setting. Preliminary work in the application of machine learning techniques, such as reinforcement learning, to aircraft maneuvering have shown promise. These studies used simplified interfaces between machine learning agent and the aircraft simulation. The simulations employed low order equivalent system models. High-fidelity aircraft simulations exist, such as the simulations developed by NASA at its Dryden Flight Research Center. To expand the applicational domain of reinforcement learning to aircraft designs, this study presents a series of experiments that examine a reinforcement learning agent in the role of test pilot. The NASA X-31 and F-106 high-fidelity simulations provide realistic aircraft for the agent to maneuver. The approach of the study is to examine an agent possessing a genetic-based, artificial neural network to approximate long-term, expected cost (Bellman value) in a basic maneuvering task. The experiments evaluate different learning methods based on a common feedback function and an identical task. The learning methods evaluated are: Q-learning, Q(lambda)-learning, SARSA learning, and SARSA(lambda) learning. Experimental results indicate that, while prediction error remain quite high, similar, repeatable behaviors occur in both aircraft. Similar behavior exhibits portability of the agent between aircraft with different handling qualities (dynamics). Besides the adaptive behavior aspects of the study, the genetic algorithm used in the agent is shown to play an additive role in the shaping of the artificial neural network to the prediction task.

Given the limited human resources available to interact directly with the public and disseminate information on earthquake and tsunami safety, the Puerto Rico Seismic Network has developed the Train the Trainers course, designed exclusively for emergency management officers (EMOs). This three-day training course provides a complete package of educational tools that will allow EMOs to present standard conferences, and lectures, with the appropriate and accurate information for different audiences on earthquake and tsunami hazard and safety. Here we present preliminary observations and lessons learned from the pilot program that was offered in July 2017 to 20 EMOs from the twelve Puerto Rico Emergency Management Agency (PREMA) zones and two students from the University of Puerto Rico Mayaguez. To ensure sufficient preparation, the training course provided evaluation tools including written and practical exams that participants were required to score 80% or more to complete the training successfully. Of the 20 EMO participants, 18 EMOs passed the final exam. Preliminary analysis of the pre-test scores and the post-test scores, show a score improvement between 8% to 46% amongst the participants. These 18 participants will receive a certificate as well as tools and resources to offer earthquakes and tsunamis conferences for up to two years across Puerto Rico and its outlying islands. To ensure that the pilot participants will provide conferences to the public PRSN required a signed commitment to give at least 5 conferences in one year from each participant and PRSN will monitor the participants for the next two years to evaluate the efficacy of the program. However, based on the preliminary data this program appears to be an effective method to increase the amount of outreach professionals on the Island.

Healing pathways: art therapy for American Indian cancer survivors.

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.

Previous studies have shown graphical presentation methods of hazardous wind shear to be superior to textual or audible warnings alone. Positional information and the strength of the hazard were observed to be and were cited by pilots as the most important factors in a display. In this experiment the use of the three different graphical presentations of hazardous wind shear are examined. Airborne predictive detectors of wind shear enable the dissemination of varying levels of information. The effectiveness of iconic and mapping display modes of different complexities are addressed through simulation and analysis. Different positional and time-varying situations are presented in a 'part-task' Boeing 767 simulator using data from actual microburst events. Experienced airline pilots fly approach profiles using both iconic and F-map wind shear alerting displays. Microburst accompanied each event is also shown to the pilot. Mapping display types are expected to be found exceptionally efficient at conveying location comparison information while iconic displays simplify the threat recognition process. Preliminary results from the simulator study are presented. Recommendations concerning the suitability of multilevel iconic and mapping displays are made. Situational problems with current display prototypes are also addressed.

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

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.

2012-01-01

Results from this 1-year pilot study yielded an intriguing combination of findings that warrant further investigation. Observations include reduced numbers of roosting birds along the Texas coast during dry conditions, highly dynamic use of nocturnal roost sites, use of widely divergent habitat types for foraging, low body mass of most captured birds, and apparent fidelity to general feeding areas. Future investigations of this eastern winter population of curlews would benefit from larger sample sizes and monitoring of individual birds.

A concept for automating the control of air traffic in the terminal area in which the primary man-machine interface is the cockpit is described. The ground and airborne inputs required for implementing this concept are discussed. Digital data link requirements of 10,000 bits per second are explained. A particular implementation of this concept including a sequencing and separation algorithm which generates flight paths and implements a natural order landing sequence is presented. Onboard computer/display avionics utilizing a traffic situation display is described. A preliminary simulation of this concept has been developed which includes a simple, efficient sequencing algorithm and a complete aircraft dynamics model. This simulated jet transport was flown through automated terminal-area traffic situations by pilots using relatively sophisticated displays, and pilot performance and observations are discussed.

Objective This study aimed to determine the feasibility and preliminary efficacy of a post-operative telephone-based cognitive behavioral therapy intervention (Tele-CBT) in improving eating pathology and psychosocial functioning. Methods Six-month post-operative bariatric surgery patients (n = 19) received six sessions of Tele-CBT. Study outcome variables included binge eating (BES), emotional eating (EES), depressive symptoms (PHQ-9), and anxiety symptoms (GAD-7). Results Retention was 73.7 % post-intervention. Tele-CBT resulted in significant reductions in mean difference scores on BES, EES-Total, EES-Anxiety, EES-Anger, PHQ9, and GAD7. Tele-CBT patients experienced a mean weight loss of 8.62 ± 15.02 kg between 6-months post-surgery (pre-Tele-CBT) and 12-months post-surgery. Conclusions These preliminary results suggest that post-surgery Tele-CBT is feasible and can improve post-surgery symptoms of psychopathology in this uncontrolled study, supporting the need for a randomized controlled trial.

Rationale There is presently no approved single treatment for dual alcohol and nicotine dependencies. Objective This pilot study investigated baclofen effects in alcoholic smokers. Methods This was a preliminary double-blind placebo-controlled randomized clinical study with 30 alcoholic smokers randomized to baclofen at 80 mg/day or placebo. A subgroup (n=18) participated in an alcohol cue-reactivity experiment. Results Baclofen, compared with placebo, significantly decreased the percent days of abstinence from alcohol-tobacco co-use (p=0.004). Alcohol dependence severity moderated baclofen effects, with the higher severity group having the greater baclofen response (p<0.001). Although the percent days of alcohol-tobacco co-use declined in both groups, this decline was greater after placebo than baclofen (p<0.001). Secondary analyses on alcohol or tobacco use alone suggested that the increase in percent days of co-abstinence was driven by the medication differences on heavy drinking days and on percent days smoking. In the cue-reactivity substudy, baclofen slightly decreased alcohol urge (p=0.058) and significantly reduced salivation (p=0.001), but these effects were not related to cue type. Conclusions This study provides preliminary evidence suggesting a possible role of baclofen in the treatment of alcoholic smokers. However, the mixed results and the small sample require larger confirmatory studies. PMID:24973894

Brain response to taste in overweight children: A pilot feasibility study.

2017-01-01

Understanding the neural response to food and food cues during early stages of weight gain in childhood may help us determine the drive processes involved in unhealthy eating behavior and risk for obesity. Healthy weight and overweight children ages 6-8 (N = 18; 10 with BMI between 5th and 85th %ile and 8 with BMI >85th %ile) underwent fMRI scans while anticipating and receiving tastes of chocolate milkshake. Parents completed a Children's Eating Behaviour Questionnaire. Results reveal greater response to milkshake taste receipt in overweight children in the right insula, operculum, precentral gyrus, and angular gyrus, and bilateral precuneus and posterior cingulate. No group differences were found for brain response to a visual food cue. Exploratory analyses revealed interactions between self-report measures of eating behavior and weight status on brain response to taste. This pilot study provides preliminary evidence of feasibility of studying young children's taste processing and suggests a possible developmental shift in brain response to taste.

The aim of this pilot study was to evaluate the prevalence of gingival recession at buccal tooth surfaces in a student population of Bologna University Dental School. A total of 55 subjects, attending the 1st and 5th year of the course were examined. The clinical examination involved assessment of plaque, calculus, width of keratinized gingiva, buccal probing depth and buccal gingival recession. Information about toothbrushing behavior was collected in an interview. The multiple regression analysis showed that level of education (p=0.002), toothbrushing technique (p=0.013) and toothbrushing frequency (p=0.016) are significant contributors to gingival recession. Notwithstanding the limits of a preliminary study, a higher prevalence of buccal recession is observed in the final year students, which have also a significantly lower % of buccal surfaces with calculus (p=0.014). In addition, it clearly appears that there is the necessity to investigate other factors connected with toothbrushing (pressure, time, toothpaste quantity) in order to provide an oral hygiene education without undesired effects.

Set-shifting (SS) difficulties and weak central coherence (CC) are commonly associated with autism spectrum disorders (ASD). Cognitive remediation therapy (CRT) aims to improve such cognitive processing; however, there are no reports on CRT for patients with ASD. This pilot study aimed to provide preliminary evidence to support the use of CRT for individuals with ASD and provide data to inform future studies. Nineteen individuals with ASD were recruited and administered a series of neuropsychological and questionnaire measures to examine cognitive function and clinical outcomes such as anxiety and depression. Participants received CRT, and cognitive function and clinical variables were re-evaluated at postintervention and after 3 months. The participants demonstrated significant improvement in CC and anxiety at postintervention, which was maintained at 3-month follow-up. Although SS scores had improved with a large effect size, this was not statistically significant. CRT improved CC and anxiety scores for individuals with ASD, suggesting that CRT is an effective treatment for individuals with ASD.

High rates of missed appointments and attrition are common barriers to treatment for adolescents attending outpatient mental health treatment. Such figures indicate a need for innovative strategies to engage youth in treatment. The current quasi-experimental pilot study examined the feasibility, acceptability, and preliminary efficacy of text message (TM) appointment reminders to improve attendance in a sample of 48 adolescents attending outpatient therapy. The sample was approximately 46% Latino and 40% African American with an equal number of males and females. Adolescents receiving TM reminders demonstrated significantly higher rates of attendance (65%) than a historical control group (49%) (p < .05). Participants in the TM group received reminders for the majority (88%) of their scheduled sessions with only 4% of reminders not received due to phone-related problems. Additionally, TM reminders received high patient satisfaction ratings. Findings from the present study suggest that TM reminders may be a cost-effective and developmentally appropriate strategy for engaging adolescents in treatment.

Preliminary juvenile Lost River and shortnose sucker investigations in Clear Lake, California--2011 pilot study summary

USGS Publications Warehouse

Burdick, Summer M.; Rasmussen, Josh

2012-01-01

Poor recruitment appears to limit the recovery of Lost River and shortnose sucker populations in Clear Lake Reservoir, California, but the cause is unknown. Adult suckers migrate up Willow Creek and its tributaries to spawn in some years, but low flow in Willow Creek may inhibit spawning migrations in other years. It is unclear whether spawning is successful, larvae survive, or juveniles persist to adulthood. Environmental variables associated with successful spawning or young-of-year survival have not been identified and early life history for these populations is poorly understood. The U.S. Geological Survey in cooperation with the U.S. Fish and Wildlife Service and Ruby Pipeline L.L.C. Corporation (El Paso, Tex.) initiated a study in 2011 to better understand juvenile sucker life history in Clear Lake Reservoir, and to identify constraints in the early life history that may limit recruitment to the adult spawning populations. This is a report on the 2011 pilot study for this project.

Preliminary performance estimates of an oblique, all-wing, remotely piloted vehicle for air-to-air combat

1974-01-01

A computerized aircraft synthesis program has been used to assess the effects of various vehicle and mission parameters on the performance of an oblique, all-wing, remotely piloted vehicle (RPV) for the highly maneuverable, air-to-air combat role. The study mission consists of an outbound cruise, an acceleration phase, a series of subsonic and supersonic turns, and a return cruise. The results are presented in terms of both the required vehicle weight to accomplish this mission and the combat effectiveness as measured by turning and acceleration capability. This report describes the synthesis program, the mission, the vehicle, and results from sensitivity studies. An optimization process has been used to establish the nominal RPV configuration of the oblique, all-wing concept for the specified mission. In comparison to a previously studied conventional wing-body canard design for the same mission, this oblique, all-wing nominal vehicle is lighter in weight and has higher performance.

A family of three Close Air Support aircraft is presented. These aircraft are designed with commonality as the main design objective to reduce the life cycle cost. The aircraft are low wing, twin-boom, pusher turbo-prop configurations. The amount of information displayed to the pilot was reduced to a minimum to greatly simplify the cockpit. The aircraft met the mission specifications and the performance and cost characteristics compared well with other CAS aircraft. The concept of a family of CAS aircraft seems viable after preliminary design.

In a pilot randomized controlled trial, examine the feasibility and preliminary efficacy of an 8-week, mindfulness training program (Mindfulness Based Stress Reduction) in a sample of men on active surveillance on important psychological outcomes including prostate cancer anxiety, uncertainty intolerance and posttraumatic growth. Men were randomized to either mindfulness (n = 24) or an attention control arm (n = 19) and completed self-reported measures of prostate cancer anxiety, uncertainty intolerance, global quality of life, mindfulness and posttraumatic growth at baseline, 8 weeks, 6 months and 12 months. Participants in the mindfulness arm demonstrated significant decreases in prostate cancer anxiety and uncertainty intolerance, and significant increases in mindfulness, global mental health and posttraumatic growth. Participants in the control condition also demonstrated significant increases in mindfulness over time. Longitudinal increases in posttraumatic growth were significantly larger in the mindfulness arm than they were in the control arm. While mindfulness training was found to be generally feasible and acceptable among participants who enrolled in the 8-week intervention as determined by completion rates and open-ended survey responses, the response rate between initial enrollment and the total number of men approached was lower than desired (47%). While larger sample sizes are necessary to examine the efficacy of mindfulness training on important psychological outcomes, in this pilot study posttraumatic growth was shown to significantly increase over time for men in the treatment group. Mindfulness training has the potential to help men cope more effectively with some of the stressors and uncertainties associated with active surveillance. Copyright © 2016 John Wiley & Sons, Ltd.

Media-based rehabilitation provides a powerful opportunity to examine vocational behaviors in the disability sector. However, this research is preliminary at best. This paper reports pilot data. Eighteen adults with multiple sclerosis (MS) accessed an email-delivered, resource-based package, Work and MS. Pre- and post-access vocational self-efficacy and identity (Job-Procurement Self Efficacy Scale, My Vocational Situation Scale- primary outcomes), life orientation and depressed mood (Life Orientation Test - revised and Patient Health Questionnaire-9 - secondary outcomes) were assessed. Pre- and post-change scores were examined with Wilcoxon signed ranks tests and Hedges g effect sizes with associated 95% confidence intervals. Reliable change analyses were additionally calculated to determine the clinical significance of individual change scores. Significant and positive effects were reported for vocational self-efficacy, identity, and optimism. Reliable change scores in one or more of these key outcomes were reported by 30% of the sample. Satisfaction with the content and delivery of the email-based intervention was also noted. Preliminary evidence suggests that Work and MS can help to promote vocational goals, interests and strengths among job seekers with a disability by providing a set of tools, information and linkages relating to vocational pursuits and career development. Replication with a randomized control design is indicated. Implications for Rehabilitation Research indicates a high unemployment rate among working-age adults with MS. A combination of disease-specific, psychological, programmatic and societal variables contribute to employment instability in this group. This pilot study demonstrates that an e-mail-based resource package, Work and MS, provides an innovative and feasible option for promoting consumer engagement with vocational services and, potentially, improving vocational outcomes. Work and MS has potential applicability to other disability groups.

A Comparison of Two Control Display Unit Concepts on Flight Management System Training

NASA Technical Reports Server (NTRS)

Abbott, Terence S.

1997-01-01

One of the biggest challenges for a pilot in the transition to a 'glass' cockpit is understanding the flight management system (FMS). Because of both the complex nature of the FMS and the pilot-FMS interface, a large portion of transition training is devoted to the FMS. The current study examined the impact of the primary pilot-FMS interface, the control display unit (CDU), on FMS training. Based on the hypothesis that the interface design could have a significant impact on training, an FMS simulation with two separate interfaces was developed. One interface was similar to a current-generation design, and the other was a multiwindows CDU based on graphical user interface techniques. For both application and evaluation reasons, constraints were applied to the graphical CDU design to maintain as much similarity as possible with the conventional CDU. This preliminary experiment was conducted to evaluate the interface effects on training. Sixteen pilots with no FMS experience were used in a between-subjects test. A time-compressed, airline-type FMS training environment was simulated. The subjects were trained to a fixed-time criterion, and performance was measured in a final, full-mission simulation context. This paper describes the technical approach, simulation implementation, and experimental results of this effort.

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.

Quality of life is negatively affected in children with food allergy. Oral immunotherapy is an approach to food allergy that leads to patient desensitization by administering gradually increasing amounts of a given food allergen. The aim of this pilot study is to evaluate how oral immunotherapy affects quality of life in children allergic to cow milk proteins. Thirty children (aged 3-12 years) with cow milk allergy were recruited. Their parents were provided with a validated disease specific quality of life questionnaire (the food allergy quality of life questionnaire -- parent form, FAQLQ-PF) before and again 2 months after completing an oral immunotherapy protocol with cow milk. A significant improvement in all the investigated domains -- emotional impact, food anxiety and social and dietary limitations -- was found. The separate analysis of the different age groups demonstrated that the emotional impact and the food-related anxiety improved in children older than 4, while the social domains improved in each age group. In this pilot experience, oral immunotherapy significantly improves quality of life in children with cow milk allergy. The improvement seems particularly evident in children over 4 years old, who are most likely to benefit from the oral immunotherapy approach. Further placebo-controlled studies are needed to confirm these preliminary results.

Objectives Assess the feasibility of implementing the GoActive intervention in secondary schools, to identify improvements, test study procedures, determine preliminary effectiveness to increase moderate-to-vigorous physical activity (MVPA), and inform power calculations to establish programme effectiveness. Setting Feasibility study (1 school) and pilot cluster-randomised controlled trial (CRCT; 2 intervention; 1 control school(s)). Participants 460 participants (46.6% female; 13.2 (0.4) years old). Interventions 8-week intervention (2013) involved: classes choosing weekly activities encouraged by mentors (older adolescents) and in-class peer leaders. Students gain points for trying activities which are entered into an intramural competition. Primary and secondary outcome measures Planned quantitative (questionnaire) and qualitative (focus groups) process evaluation addressed enjoyment, confidence, participation, suggested improvements. Outcomes were assessed at baseline and follow-up (week 8) in pilot CRCT and included accelerometer-assessed MVPA; adolescent-reported activity type, well-being, peer support, shyness, sociability. Analysis of covariance was used to assess preliminary effectiveness as change in MVPA adjusted for baseline. Results All year 9 students in intervention schools were exposed to the intervention; over all schools 77% of eligible students were measured. 71% boys and 74% girls found GoActive ‘fun’; 38% boys and 32% girls said it increased confidence, and 64% boys and 59% girls said they would continue with a GoActive activity. Suggested improvements included more mentorship; improved training; streamlined points recording. Pilot results indicated potential effectiveness ((adjusted mean difference (95% CI) p value; MVPA mins; 5.1 (1.1 to 9.2) p=0.014)) and suggest recruitment of 16 schools (2400 adolescents) for a full trial. Compared with control, intervention students reported greater peer support 0.5 (0.1 to 0.9) p=0.03, well-being 1.8 (0.1 to 3.4) p=0.04 but no difference in shyness/sociability. Participation in activity types approached significance (intervention group 2.3 (−0.2 to 4.7) p=0.07 more activity types). Conclusions Results suggest feasibility and indicate potential effectiveness of GoActive to increase MVPA and support a fully powered evaluation of effectiveness and cost-effectiveness. Process evaluation data were used to refine GoActive prior to a full trial. Trial registration number ISRCTN31583496; pre-results. PMID:27836873

Hedlund, Sofia; Nilsson, Hans; Lenz, Markus; Sundberg, Tobias

2014-02-01

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.

Parthasarathy, Sairam; Wendel, Christopher; Haynes, Patricia L.; Atwood, Charles; Kuna, Samuel

2013-01-01

Study Objectives: To evaluate patient ratings of the acceptability of a peer buddy system (PBS). To promote continuous positive airway pressure (CPAP) therapy adherence in patients with obstructive sleep apnea (OSA). To obtain preliminary data on the effectiveness of PBS on sleep-specific health-related quality of life and CPAP adherence. Design: Prospective, randomized, and controlled study. Setting: Academic Center. Participants: Thirty-nine patients with OSA and 13 patients with OSA who were experienced CPAP users. Interventions: Recently diagnosed patients with OSA were randomly assigned to either the PBS to promote CPAP adherence (intervention group) or usual care (control group). Measurements: Patient satisfaction, Functional Outcomes of Sleep Questionnaire (FOSQ), CPAP adherence, vigilance, self-efficacy, and patient activation were measured. Results: Ninety-one percent of the subjects rated the PBS as very satisfactory (68%) or satisfactory (23%). During the 90 days of therapy, weekly CPAP adherence was greater in the intervention than the usual care group (MANOVA; F = 2.29; p = 0.04). Patient satisfaction was positively correlated with CPAP adherence (R2 = 0.14; p = 0.02). We did not find any group differences for FOSQ, vigilance, self-efficacy, or patient activation in this pilot study. Conclusion: Our pilot study suggests that the PBS intervention is feasible and received high patient satisfaction ratings. CPAP adherence may be improved by peer-driven intervention, but a larger, adequately powered study is needed. Clinical Trial Information: ClinicalTrials.gov identifier: NCT01164683.

Adolescents with autism spectrum disorder (ASD) are at high risk for anxiety difficulties and disorders. Clinic-based cognitive behavioral therapy (CBT) is effective; however, few published school-based CBT programs for youth with ASD exist. In this study, the Facing Your Fears CBT protocol was adapted for delivery and piloted within a school setting by non-clinicians, with culturally appropriate adaptations. 44 13-15 aged youth with ASD from 22 mainstream schools in Singapore participated. Feasibility, acceptability and preliminary treatment outcomes were examined. Decreases in youth and parent reported anxiety symptoms were reported. Staff and parents found the program useful. Stakeholder support was important for implementation. Initial findings reflect the importance of carefully bridging research-to-practice for youth with ASD and anxiety.

QUETIAPINE IMPROVES RESPONSE INHIBITION IN ALCOHOL DEPENDENT PATIENTS: A PLACEBO-CONTROLLED PILOT STUDY

PubMed Central

Moallem, Nathasha; Ray, Lara A.

2013-01-01

Rationale Quetiapine has been shown to be a promising medication for the treatment of alcoholism. As an atypical antipsychotic medication with antagonist activity at D1 and D2, 5-HT1A and 5-HT2A, H1 and α1 and α2 receptors, quetiapine has been found to decrease impulsivity in other psychiatric disorders but its effects on impulsivity have not been studied in alcohol dependent patients. Objective This study seeks to test the effects of quetiapine on a specific dimension of impulsivity, namely response inhibition. This pilot study seeks to further elucidate the mechanisms of action of quetiapine for alcohol use disorders. Method A total of 20 non-treatment seeking alcohol dependent individuals were randomized to one of the following conditions in a double-blind, placebo-controlled design: (1) quetiapine (400 mg/day); or (2) matched placebo. Participants completed two counterbalanced intravenous placebo-alcohol administration sessions as well as behavioral measure of response inhibition (i.e. stop signal task) pre and post placebo-alcohol administration sessions. Results Analyses revealed a significant effect of quetiapine in improving response inhibition as measured by the stop signal task. These results provide preliminary evidence suggesting that quetiapine improves response inhibition in alcohol dependent patients, as compared to placebo. Conclusion This pilot study contributes a novel putative mechanism of action of quetiapine in alcoholism, namely an improvement in response inhibition. PMID:22037407

Effects of self-compassion workbook training on trauma-related guilt in a sample of homeless veterans: a pilot study.

PubMed

Held, Philip; Owens, Gina P

2015-06-01

The present pilot study examined the effects of a 4-week-long self-administered self-compassion training on trauma-related guilt and compared it to a stress inoculation control group. A total of 47 homeless male veterans who were living in transitional housing facilities volunteered to participate in this study. Participants were randomly assigned to either a self-compassion (N = 13) or a stress inoculation (N = 14) group and were asked to complete pre-, mid-, and postintervention assessments measuring changes in self-compassion, trauma-related guilt, and posttraumatic stress disorder severity. Participants in both interventions reported increased levels of self-compassion and equal reductions in trauma-related guilt. No other significant changes were noted. The results from this pilot study provide preliminary evidence for the use of self-compassion and stress inoculation trainings as effective interventions for trauma-related guilt. The findings also suggest that self-administered trainings in the form of workbooks may be a viable, cost-effective form of intervention for disadvantaged populations, such as homeless veterans in transitional housing, who may lack resources or access to professionals or paraprofessionals. The effects of both self-compassion training and stress inoculation training on the study variables and directions for future research on self-compassion and trauma-related guilt are discussed. © 2015 Wiley Periodicals, Inc.

The current study sought to conduct a preliminary investigation of the effectiveness and feasibility of a novel, self-guided online self-compassion training for reducing psychological distress and increasing self-compassion and happiness among psychology trainees. A 6-week online self-compassion cultivation program was developed and delivered to Australian psychology trainees (n = 37), and a pre-experimental repeated-measures design was used to collect change data on self-compassion, happiness, perceived stress, emotion regulation difficulties as well as symptoms of depression, anxiety, and stress. Participants reported significant increases in self-compassion and happiness and significant decreases in depression, stress, and emotion regulation difficulties between pretest and posttest, with the majority of changes maintained at 3-month follow up.  This study provides preliminary evidence supporting the effectiveness and acceptability of online self-compassion training as a positive, integrated, and meaningful way of reducing distress and promoting self-compassion and happiness among trainee psychologists. © 2016 Wiley Periodicals, Inc.

Information professionals' participation in interdisciplinary research: a preliminary study of factors affecting successful collaborations.

Lorenzetti, Diane L; Rutherford, Gayle

2012-12-01

This pilot study explores the conditions that support or hinder information professionals' participation in interdisciplinary research teams. We undertook a preliminary grounded theory study investigating factors that impact on information professionals' participation in interdisciplinary research. Four biomedical information professionals working in academic universities and teaching hospitals in Canada participated in semi-structured interviews. Grounded theory methods guided the data collection and analysis. Participants identified the conditions that support or hinder research participation as belonging to four distinct overlapping domains: client-level factors including preconceptions and researcher resistance; individual-level factors such as research readiness; opportunities that are most often made not found; and organisational supports. Creating willingness, building preparedness and capitalising on opportunity appear crucial to successful participation in interdisciplinary research. Further exploration of the importance of educational, collegial and organisational supports may reveal additional data to support the development of a grounded theory regarding the facilitation of information professionals' engagement in interdisciplinary research. © 2012 The authors.

Suicide intervention training evaluation: a preliminary report.

PubMed

Tierney, R J

1994-01-01

To date, very little work has been done on evaluating training in suicide intervention. This study developed and piloted a comprehensive method for evaluating suicide intervention training by applying three studies of immediate training effects on (a) suicide intervention abilities, (b) attitudes to suicide and suicide intervention, and (c) knowledge about suicide. The focus of the evaluation was a broadly used 2-day suicide intervention training program. Changes in suicide intervention abilities were measured by the Suicide Intervention Response Inventory (SIRI) and by performance in simulated suicide intervention situations, scored with the Suicide Intervention Protocol (SIP). Subjects consisted of 19 workshop participants in a pre-post condition and 17 participants in a post-test only condition. Results indicated significant increases in skills in suicide intervention situations. No significant effects were noted on the SIRI. Results from the attitudes and knowledge studies were very preliminary. They are reported here so that others may become aware of the methodology being used and the status of evaluation of the target program. Implications for further research are discussed.

Augmenting Prolonged Exposure therapy for PTSD with intranasal oxytocin: A randomized, placebo-controlled pilot trial.

PubMed

Posttraumatic stress disorder (PTSD) is a chronic, debilitating condition for which Prolonged Exposure (PE) therapy is highly efficacious. However, for some individuals, premature dropout and residual PTSD symptoms remain obstacles. The neuropeptide oxytocin is a promising candidate to enhance PE due to its ability to enhance 1) prosocial cognition and behavior, which are theorized to promote positive working alliance, and 2) extinction learning, which is the central mechanism of action underlying successful PE treatment. Despite a robust theoretical rationale, no studies to date have combined evidence-based psychotherapy for PTSD with oxytocin. This randomized, placebo-controlled, double-blind pilot trial examined the feasibility, safety, and preliminary efficacy of augmenting PE with oxytocin. Participants were 17 individuals with diverse index traumas. Participants self-administered intranasal oxytocin (40 IU) or matching placebo 45 min prior to each weekly PE therapy session. One adverse event occurred in the placebo group and three individuals dropped out (17.6%; 2 oxytocin group and 1 placebo group). The oxytocin group demonstrated lower PTSD and depression symptoms during PE, and had higher working alliance scores, although these differences did not reach statistical significance. Although preliminary, the findings support the feasibility of oxytocin combined with PE. Adequately powered studies are necessary to determine whether oxytocin enhances PE treatment outcomes and to examine potential mechanisms, such as accelerating extinction learning, enhancing early response, and preventing premature dropout.

Predicting discovery rates of genomic features.

PubMed

Gravel, Simon

2014-06-01

Successful sequencing experiments require judicious sample selection. However, this selection must often be performed on the basis of limited preliminary data. Predicting the statistical properties of the final sample based on preliminary data can be challenging, because numerous uncertain model assumptions may be involved. Here, we ask whether we can predict "omics" variation across many samples by sequencing only a fraction of them. In the infinite-genome limit, we find that a pilot study sequencing 5% of a population is sufficient to predict the number of genetic variants in the entire population within 6% of the correct value, using an estimator agnostic to demography, selection, or population structure. To reach similar accuracy in a finite genome with millions of polymorphisms, the pilot study would require ∼15% of the population. We present computationally efficient jackknife and linear programming methods that exhibit substantially less bias than the state of the art when applied to simulated data and subsampled 1000 Genomes Project data. Extrapolating based on the National Heart, Lung, and Blood Institute Exome Sequencing Project data, we predict that 7.2% of sites in the capture region would be variable in a sample of 50,000 African Americans and 8.8% in a European sample of equal size. Finally, we show how the linear programming method can also predict discovery rates of various genomic features, such as the number of transcription factor binding sites across different cell types.

2017-08-01

Spironolactone improves outcome in dogs with advanced myxomatous mitral valve disease (MMVD). Its efficacy in preclinical MMVD is unknown. The hypothesis was the administration of spironolactone to dogs with compensated MMVD demonstrating risk factors for poorer prognosis will decrease the rate of disease progression. The aim was to provide pilot data to evaluate preliminary effects and sample size calculation for a definitive clinical trial. Twenty-five client-owned dogs with MMVD with at least one of the following; left atrial to aortic ratio (LA:Ao) ≥ 1.5, normalized left ventricular internal diameter in diastole ≥ 1.6), N-terminal pro-B-type natriuretic peptide (NT-proBNP) > 550 pmol/L, cardiac troponin I > 0.025 ng/mL. Prospective, single-center, equally randomized, placebo-controlled, double-blinded, parallel grouped pilot study. No dogs were receiving medications for cardiac disease before the enrollment. Twelve dogs received placebo; 13 received spironolactone. One dog in the spironolactone group died suddenly, 1 developed congestive heart failure, and 2 received suboptimal spironolactone doses. At enrollment, NT-proBNP was significantly higher in the spironolactone group (p=0.005). Left atrial to aortic ratio (p=0.002) and left ventricular internal diameter in diastole (p=0.005) increased over time in the placebo group, but not the spironolactone group; the change did not differ significantly between groups. The change in biomarker concentrations did not differ significantly between groups; there was a tendency toward an increase in NT-proBNP over time in the placebo group. Enrollment of 76 dogs would be necessary to demonstrate a difference in the change in LA:Ao over 6 months between the groups. Preliminary results support undertaking a larger clinical trial of treatment of dogs with preclinical MMVD with spironolactone. Copyright © 2017 Elsevier B.V. All rights reserved.

in 2008, the Surgical Council on Resident Education selected 33 residency programs to pilot its General Surgery Resident Curriculum Website Portal. The portal aims to reduce program variability in curricula, align teaching and learning with essential content, and improve resident study and performance. two online surveys were sent to all program directors and their residents before releasing the portal. Data from 32 programs and 899 residents (84%) were analyzed to determine the extent to which preimplementation characteristics supported the portal's rationale and illuminated barriers to its use and impact on learning. the need for curriculum content and access to online texts varied markedly across programs. Residents had easy onsite access to the Internet and used it heavily for immediate purposes. Fewer residents used the Web for planned activities and proactive study. On average, residents reported studying an hour or less a day. the portal appears to serve curricular resource needs and may better direct resident study. Programs are advised to consciously integrate the SCORE curriculum and portal into residency training and faculty development. 2011 Elsevier Inc. All rights reserved.

Using mobile health technology to improve behavioral skill implementation through homework in evidence-based parenting intervention for disruptive behavior disorders in youth: study protocol for intervention development and evaluation.

Chacko, Anil; Isham, Andrew; Cleek, Andrew F; McKay, Mary M

2016-01-01

Disruptive behavior disorders (DBDs) (oppositional defiant disorder (ODD) and conduct disorder (CD)) are prevalent, costly, and oftentimes chronic psychiatric disorders of childhood. Evidence-based interventions that focus on assisting parents to utilize effective skills to modify children's problematic behaviors are first-line interventions for the treatment of DBDs. Although efficacious, the effects of these interventions are often attenuated by poor implementation of the skills learned during treatment by parents, often referred to as between-session homework. The multiple family group (MFG) model is an evidence-based, skills-based intervention model for the treatment of DBDs in school-age youth residing in urban, socio-economically disadvantaged communities. While data suggest benefits of MFG on DBD behaviors, similar to other skill-based interventions, the effects of MFG are mitigated by the poor homework implementation, despite considerable efforts to support parents in homework implementation. This paper focuses on the study protocol for the development and preliminary evaluation of a theory-based, smartphone mobile health (mHealth) application (My MFG) to support homework implementation by parents participating in MFG. This paper describes a study design proposal that begins with a theoretical model, uses iterative design processes to develop My MFG to support homework implementation in MFG through a series of pilot studies, and a small-scale pilot randomised controlled trial to determine if the intervention can demonstrate change (preliminary efficacy) of My MFG in outpatient mental health settings in socioeconomically disadvantaged communities. This preliminary study aims to understand the implementation of mHealth methods to improve the effectiveness of evidence-based interventions in routine outpatient mental health care settings for youth with disruptive behavior and their families. Developing methods to augment the benefits of evidence-based interventions, such as MFG, where homework implementation is an essential mediator of treatment benefits is critical to full adoption/implementation of these intervention in routine practice settings and maximizing benefits for youth with DBDs and their families.

Williams, David R.; Kawachi, Ichiro

2013-01-01

Objectives. The recently developed social resistance framework addresses a widespread pattern in which members of some nondominant minorities tend to engage in various risky and unhealthy behaviors more than the majority group. This pilot study tested the core hypotheses derived from this innovative framework. Methods. We conducted in 2011 a nationally representative Web-based survey of 200 members of a nondominant minority group (African Americans) and 200 members of a majority group (Whites). Results. The preliminary findings supported the main premises of the framework and suggested that nondominant minorities who felt discriminated and alienated from society tended also to have higher levels of social resistance. Those with higher levels of social resistance also engaged more in risky and unhealthy behaviors—smoking, drinking, and nonuse of seat belts—than did those with lower levels of social resistance. These associations were not found in the majority group. Conclusions. These preliminary results supported the framework and suggested that social resistance might play a meaningful role in risky and unhealthy behaviors of nondominant minorities, and should be taken into account when trying to reduce health disparities.

2013-01-01

Background A preliminary survey showed half of the participating Royal Netherlands Air Force (RNLAF) F-16 fighter pilots to have nasal integument and osteocartilagenous disorders related to wearing in-flight oxygen masks. Aim To make an inventory of these disorders and possible associated factors. Methods All RNLAF F-16 pilots were requested to fill out a semi-structured questionnaire for a cross-sectional survey. Additionally, one squadron in The Netherlands and pilots in operational theater were asked to participate in a prospective study that required filling out a pain score after each flight. Pilot- and flight-related variables on all participants were collected from the RNLAF database. A linear mixed model was built to identify associated factors with the post-flight pain score. Results The response rate to the survey was 83%. Ninety of the 108 participants (88%, 6 missing) reported tenderness, irritation, pain, erythema, skin lesions, callous skin, or swelling of nasal bridge integument or architecture. Seventy-two participants (71%, 6 missing) reported their symptoms to be troublesome after a mean of 6±3 out of 10 flights (0;10, 54 missing). Sixty-six pilots participated in scoring post-flight pain. Pain scores were significantly higher if a participant had ≥3 nasal disorders, after longer than average flights, after flying abroad, and after flying with night vision goggles (respectively +2.7 points, p = 0.003; +0.2 points, p = 0.027; +1.8 points, p = 0.001; +1.2 points p = 0.005). Longer than average NVG flights and more than average NVG hours per annum decreased painscores (respectively −0.8 points, p = 0.017; −0.04 points, p = 0.005). Conclusions The majority of the RNLAF F-16 fighter pilot community has nasal disorders in the contact area of the oxygen mask, including pain. Six pilot- or flight-related characteristics influence the experienced level of pain. PMID:23505413

In support of the Bioenergy Technologies Office, the National Renewable Energy Laboratory (NREL) and the Pacific Northwest National Laboratory (PNNL) are undertaking studies of biomass conversion technologies to identify barriers and target research toward reducing conversion costs. Process designs and preliminary economic estimates for each of these pathway cases were developed using rigorous modeling tools (Aspen Plus and Chemcad). These analyses incorporated the best information available at the time of development, including data from recent pilot and bench-scale demonstrations, collaborative industrial and academic partners, and published literature and patents. This technology pathway case investigates the biological conversion of biomass derivedmore » sugars to hydrocarbon biofuels, utilizing data from recent literature references and information consistent with recent pilot scale demonstrations at NREL. Technical barriers and key research needs have been identified that should be pursued for the pathway to become competitive with petroleum-derived gasoline, diesel and jet range hydrocarbon blendstocks.« less

Pilot of a Tailored Dance Intervention to Support Function in People With Cognitive Impairment Residing in Long-Term Care: A Brief Report

Older adults who live in long-term care settings are at risk for functional decline, which may be mitigated by regular exercise. Using a single-group repeated measures design, this pilot study explored the feasibility, acceptability, and preliminary effects of a Waltz-based dance intervention delivered to 13 Canadian, English-speaking, long-term care residents with mild to moderate cognitive impairment. The findings supported intervention feasibility, based on a high completion rate (93%), level of attendance (M = 7.15 of 10 sessions) and level of engagement during dance sessions (M = 1.75 to 1.97 out of 2.00). On average, residents perceived dance sessions positively, and staff and family participants (N = 26) rated them as somewhat acceptable overall (M = 2.37, 0 to 4 scale). Additional research is needed to assess intervention efficacy in a larger sample. PMID:29085863

A Pilot Study Examining Depressive Symptoms, Internet Use, and Sexual Risk Behavior among Asian Men Who Have Sex With Men

2013-01-01

In the present paper, we present a preliminary examination of the association of depression level, internet use, meeting sexual partners online, and unprotected sexual activity among Asian men who have sex with men (MSM). Because depression level has been previously linked to increased levels of sexual risk behavior, and heightened levels of Internet use has been linked to greater depressive symptoms, the present pilot research jointly examines these factors. We found that those with higher levels of depression, measured using the CES-D, spent more time online, met significantly more sexual partners online, and reported a significantly higher number of unprotected sexual acts. Based on this initial evidence, we conclude that incorporating CES-D to screen for depression can serve as an important tool for addressing underlying dynamics of sexual risk behaviors.

The primary objective of this article was to describe the development and pilot implementation of a brief jail-based cervical health promotion intervention. The intervention was guided by a preliminary study of incarcerated women’s cervical health knowledge, awareness, and health literacy, as well as a social and feminist approach to intervention development. We developed and conducted a pilot implementation of the Sexual Health Empowerment Project to increase cervical health knowledge, reduce barriers related to beliefs about cervical cancer, and improve self-efficacy and confidence in navigating health systems. This article offers a framework for how empirically and theory-based interventions are developed and tailored for a jail setting. Future work should include the evaluation of the long-term effects of such a disease-specific program on health behaviors and outcomes among high-risk and vulnerable groups of women as they leave jails and enter communities.

2017-03-01

The study purpose was to develop and pilot an undue influence screening tool for California's Adult Protective Services (APS) personnel based on the definition of undue influence enacted into California law January 1, 2014. Methods included four focus groups with APS providers (n = 33), piloting the preliminary tool by APS personnel (n = 15), and interviews with four elder abuse experts and two APS administrators. Social service literature-including existing undue influence models-was reviewed, as were existing screening and assessment tools. Using the information from these various sources, the California Undue Influence Screening Tool (CUIST) was developed. It can be applied to APS cases and potentially adapted for use by other professionals and for use in other states. Implementation of the tool into APS practice, policy, procedures, and training of personnel will depend on the initiative of APS management. Future work will need to address the reliability and validity of CUIST.

2016-03-01

The prevention of mental, emotional, and behavioral (MEB) disorders among children and adolescents is a national priority. One mode of implementing community-wide MEB prevention efforts is through evidence-based community mobilization approaches such as Communities That Care (CTC). This article provides an overview of the CTC framework and discusses the adaptation process of CTC to prevent development of MEBs through preventing child abuse and neglect and bolstering child well-being in children aged 0 to 10. Adaptations include those to the intervention itself as well as those to the evaluation approach. Preliminary findings from the Keeping Families Together pilot study of this evolving approach suggest that the implementation was manageable for sites, and community board functioning and community adoption of a science-based approach to prevention in pilot sites looks promising. Implications and next steps are outlined. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

Chan, Eliza W C; Tam, S F

2005-01-01

The purpose of this project was to develop and pilot a web-based job placement information network aiming at enhancing the work trial and job placement opportunities of people with disabilities (PWD). Efficient uses of information technology in vocational rehabilitation were suggested to help improve PWD employment opportunities and thus enable them to contribute as responsible citizens to the society. In this preliminary study, a web-based employer network was so developed to explore Hong Kong employers' needs and intentions in employing PWD. The results indicated that Hong Kong employers generally agreed to arrange work trials for PWD whose work abilities match job requirements. They also expressed that they would offer permanent job placements to those PWD who showed satisfactory performance in work trials. The present study evidenced that using an information network could expedite communications between employers and job placement services, and thus job placement service outcomes. It is hoped that a job placement databank could thus be developed through accumulating responses from potential employers.

We conducted a two-period (open-label and double-blind) pilot investigation of droxidopa, with and without carbidopa, for ADHD. Twenty adult ADHD patients received open-label droxidopa titrated from 200 to 600 mg 3 times per day (TID; Weeks 1-3), then open-label droxidopa plus carbidopa titrated from 25 or 50 mg TID (Weeks 4-6). In Weeks 7 to 8, patients were randomized to continued co-treatment or matching placebo substitution. Improvements in mean total Adult ADHD Investigator Symptom Report Scale (AISRS) scores were seen at Week 1 (p < .0001) and Week 3 (p < .0001). Improvements were maintained but not increased with carbidopa. Thirteen of 20 patients completed open-label treatment. In the double-blind period, mean total AISRS scores were similar between the co-treatment (n = 6) and placebo (n = 5) groups. No serious adverse events were reported. These preliminary findings indicate that droxidopa can improve adult ADHD symptoms. Further studies are warranted to examine the efficacy and safety of droxidopa in ADHD. © 2015 SAGE Publications.

The present pilot study aims at analyzing the human activity of playing in the light of an indicator of human ecology (HE). We highlighted the four essential anthropological dimensions (FEAD), starting from the analysis of questionnaires administered to actual gamers. The coherence between theoretical construct and observational data is a remarkable proof-of-concept of the possibility of establishing an experimentally motivated link between a philosophical construct (coming from Huizinga's Homo ludens definition) and actual gamers' motivation pattern. The starting hypothesis is that the activity of playing becomes ecological (and thus not harmful) when it achieves the harmony between the FEAD, thus realizing HE; conversely, it becomes at risk of creating some form of addiction, when destroying FEAD balance. We analyzed the data by means of variable clustering (oblique principal components) so to experimentally verify the existence of the hypothesized dimensions. The subsequent projection of statistical units (gamers) on the orthogonal space spanned by principal components allowed us to generate a meaningful, albeit preliminary, clusterization of gamer profiles.

This pilot study examined the feasibility of (1) conducting interdisciplinary fall risk screens at a communitywide adult fall prevention event and (2) collecting preliminary follow-up data from people screened at the event about balance confidence and home and activity modifications made after receiving educational information at the event. We conducted a pilot study with pre- and posttesting (4-mo follow-up) with 35 community-dwelling adults ≥55 yr old. Approximately half the participants were at risk for falls. Most participants who anticipated making environmental or activity changes to reduce fall risk initiated changes (n = 8/11; 72.7%) during the 4-mo follow-up period. We found no significant difference in participants' balance confidence between baseline (median = 62.81) and follow-up (median = 64.06) as measured by the Activities-specific Balance Confidence scale. Conducting interdisciplinary fall risk screens at an adult fall prevention event is feasible and can facilitate environmental and behavior changes to reduce fall risk.

This pilot study explored the preliminary efficacy, parent acceptability and economic cost of delivering Step One within Stepped Care Trauma-Focused Cognitive Behavioral Therapy (SC-TF-CBT). Nine young children ages 3–6 years and their parents participated in SC-TF-CBT. Eighty-three percent (5/6) of the children who completed Step One treatment and 55.6 % (5/9) of the intent-to-treat sample responded to Step One. One case relapsed at post-assessment. Treatment gains were maintained at 3-month follow-up. Generally, parents found Step One to be acceptable and were satisfied with treatment. At 3-month follow-up, the cost per unit improvement for posttraumatic stress symptoms and severity ranged from $27.65 to $131.33 for the responders and from $36.12 to $208.11 for the intent-to-treat sample. Further research on stepped care for young children is warranted to examine if this approach is more efficient, accessible and cost-effective than traditional therapy. PMID:23584728

This pilot study tested the efficacy of a brief intervention using motivational interviewing (MI) plus mindfulness meditation (MM) to reduce marijuana use among young adult female. Thirty-four female marijuana users between the ages of 18–29 were randomized to either the intervention group (n = 22), consisting of 2 sessions of MI-MM or an assessment-only control group (n = 12). Participants’ marijuana use was assessed at baseline, 1, 2, and 3 months post-treatment. Fixed-effects regression modeling was used to analyze treatment effects. Participants randomized to the intervention group were found to use marijuana on 6.15 (z = −2.42, p=.015), 7.81 (z = −2.78, p=.005), and 6.83 (z = −2.23, p=.026) fewer days at months 1, 2, and 3, respectively, than controls. Findings from this pilot study provide preliminary evidence for the feasibility and effectiveness of a brief MI-MM for young adult female marijuana users. PMID:21940136

Impact of Ada in the Flight Dynamics Division: Excitement and frustration

1993-01-01

In 1985, NASA Goddard's Flight Dynamics Division (FDD) began investigating how the Ada language might apply to their software development projects. Although they began cautiously using Ada on only a few pilot projects, they expected that, if the Ada pilots showed promising results, they would fully transition their entire development organization from FORTRAN to Ada within 10 years. However, nearly 9 years later, the FDD still produces 80 percent of its software in FORTRAN, despite positive results on Ada projects. This paper reports preliminary results of an ongoing study, commissioned by the FDD, to quantify the impact of Ada in the FDD, to determine why Ada has not flourished, and to recommend future directions regarding Ada. Project trends in both languages are examined as are external factors and cultural issues that affected the infusion of this technology. This paper is the first public report on the Ada assessment study, which will conclude with a comprehensive final report in mid 1994.

2015-12-01

After the second phase of the Global Soil Wetness Project (GSWP2) as an early global continuous gridded multi-model analysis, a comprehensive set of land surface fluxes and state variables became available. It has been broadly utilized in the hydrology community, and its success has evolved to take advantages of recent scientific progress and to extend the relatively short time span (1986-1995) of the previous project. In the third phase proposed here (GSWP3), an extensive set of quantities for hydro-energy-eco systems will be produced to investigate their long-term (1901-2010) changes. The energy-water-carbon cycles and their interactions are also examined subcomponent-wise with appropriate model verifications in ensemble land simulations. In this study, the preliminary results and problems found from the first round analysis of the GSWP3 pilot study are shown. Also, it is discussed how the global offline simulation activity contributes to wider communities and a bigger scope such as Climate Model Intercomparison Project Phase 6 (CMIP6).

Steps to Enhance Early Recovery After Hematopoietic Stem Cell Transplantation: Lessons Learned From a Physical Activity Feasibility Study.

Hacker, Eileen Danaher; Peters, Tara; Patel, Pritesh; Rondelli, Damiano

This pilot study tested and refined a free-living physical activity intervention. The investigators evaluated the acceptability and feasibility of the intervention after hematopoietic stem cell transplantation and determined preliminary effects on physical activity, fatigue, muscle strength, functional ability, and quality of life. This pilot study used a 1-group, pretest-posttest design. The free-living physical activity intervention consisted of an education component and 6 weeks of gradually increasing physical activity after discharge from the hospital. The intervention was designed to increase steps by 10% weekly. Subjects were assessed before transplantation and during the seventh week after discharge from the hospital after completing the intervention. Pretest-posttest scores were analyzed with paired t tests. Subject wore the physical activity tracker for an average of 38 of 42 days and met their physical activity goals 57% of the time. Subjects reported significantly less physical fatigue after the free-living physical activity intervention compared with baseline (P = .05). Improvements in quality of life approached significance (P = .06). The findings demonstrate that the free-living physical activity intervention implemented during the very early recovery period after transplantation is feasible and acceptable. The intervention potentially reduces fatigue and improves quality of life. The positive results must be interpreted cautiously given the pilot nature of the study. The evidence supports continued investigation.

The purpose of this pilot study is to evaluate the feasibility of a cognitive-behavioural training program for adolescents with chronic pain irrespective of pain localisation. A secondary aim was to give an impression of the effect of the program on pain and quality of life. Eight adolescents (14-18 years) with chronic non-organic pain recruited from the general population (and their parents) participated in this pilot study. The intervention included five group meetings alternated with four telephone contacts (during the self-management weeks) over a period of 9 weeks. The training aimed to change pain behaviour through pain education, relaxation strategies, problem-solving techniques, assertiveness training, cognitive restructuring and by stimulating the adolescent's physical activity level. The training further addresses the social context of pain by inviting parents to attend two meetings for the parents only, and by asking the adolescents to bring a peer to one of the meetings. Adolescents and their parents were positive about the program. Adolescents felt they were more in control of their pain and parents valued the support they experienced in helping their children to master the pain. The training was considered to be feasible in daily life. Further, the preliminary data showed an effect on pain and quality of life in the expected direction. The results underline the need for a definitive study with a larger sample size and a random controlled design.

The self-help industry generates billions of dollars yearly in North America. Despite the popularity of this movement, there has been surprisingly little research assessing the characteristics of self-help books consumers, and whether this consumption is associated with physiological and/or psychological markers of stress. The goal of this pilot study was to perform the first psychoneuroendocrine analysis of consumers of self-help books in comparison to nonconsumers. We tested diurnal and reactive salivary cortisol levels, personality, and depressive symptoms in 32 consumers and nonconsumers of self-help books. In an explorative secondary analysis, we also split consumers of self-help books as a function of their preference for problem-focused versus growth-oriented self-help books. The results showed that while consumers of growth-oriented self-help books presented increased cortisol reactivity to a psychosocial stressor compared to other groups, consumers of problem-focused self-help books presented higher depressive symptomatology. The results of this pilot study show that consumers with preference for either problem-focused or growth-oriented self-help books present different physiological and psychological markers of stress when compared to nonconsumers of self-help books. This preliminary study underlines the need for additional research on this issue in order to determine the impact the self-help book industry may have on consumers' stress. PMID:26839713

Clostridium difficile infections (CDI) are common, costly and potentially life threatening. Most CDI will respond to antibiotic therapy, but 3%-10% of all patients with CDI will progress to a severe, life-threatening course. Complete removal of the large bowel is indicated for severe CDI. However, the 30-day mortality following surgical intervention for severe CDI ranges from 20% to 70%. A less invasive approach using surgical faecal diversion and direct colonic lavage with polyethylene glycol (PEG) and vancomycin has demonstrated a relative mortality reduction of approximately 50%. As an alternative to these operative approaches, we propose to treat patients with bedside intestinal lavage with PEG and vancomycin instillation via nasojejunal tube, in addition to usual antibiotic management. Preliminary data collected by our research group are encouraging. We will conduct a 1-year, single-centre, pilot randomised controlled trial to study this new treatment strategy for patients with severe CDI and additional risk factors for fulminant or complicated infection. After informed consent, patients with severe-complicated CDI without immediate indication for surgery will be randomised to either usual antibiotic treatment or usual antibiotic treatment with the addition of 8 L of PEG lavage via nasojejunal tube. This pilot trial will evaluate our eligibility and enrolment rate, protocol compliance and adverse event rates and provide further data to inform a more robust sample size calculation and protocol modifications for a definitive multicentre trial design. Based on historical data, we anticipate enrolling approximately 24 patients during the 1-year pilot study period.As a pilot study, data will be reported in aggregate. Between-group differences will be assessed in a blinded fashion for evidence of harm, and to further refine our sample size calculation. This study protocol has been reviewed and approved by our local institutional review board. Results of the pilot trial and subsequent main trial will be submitted for publication in a peer-reviewed journal.

As an alternative to these operative approaches, we propose to treat patients with bedside intestinal lavage with PEG and vancomycin instillation via nasojejunal tube, in addition to usual antibiotic management. Preliminary data collected by our research group are encouraging. Methods and analysis We will conduct a 1-year, single-centre, pilot randomised controlled trial to study this new treatment strategy for patients with severe CDI and additional risk factors for fulminant or complicated infection. After informed consent, patients with severe-complicated CDI without immediate indication for surgery will be randomised to either usual antibiotic treatment or usual antibiotic treatment with the addition of 8 L of PEG lavage via nasojejunal tube. This pilot trial will evaluate our eligibility and enrolment rate, protocol compliance and adverse event rates and provide further data to inform a more robust sample size calculation and protocol modifications for a definitive multicentre trial design. Based on historical data, we anticipate enrolling approximately 24 patients during the 1-year pilot study period. As a pilot study, data will be reported in aggregate. Between-group differences will be assessed in a blinded fashion for evidence of harm, and to further refine our sample size calculation. Ethics and dissemination This study protocol has been reviewed and approved by our local institutional review board. Results of the pilot trial and subsequent main trial will be submitted for publication in a peer-reviewed journal. Trial registration number NCT02466698; Pre-results. PMID:28760801

Therapists of many persuasions emphasize the therapy relationship in their work, a priority backed by strong empirical evidence. Training in how to maximize the power and potential of the therapy relationship, however, has lagged behind. A novel approach to using the therapy relationship and to training therapists in its use is provided by Functional Analytic Psychotherapy (FAP). FAP training involves eight 2-hr weekly training sessions conducted online using web-conferencing technology. The training integrates behavioral principles with a focus on trainee-trainer and trainee-trainee relationships in a highly structured course that evokes the desirable FAP therapist-trainee behaviors and collectively shapes the behaviors through reinforcement by the trainer and other trainees. In a preliminary study, 16 therapist-trainees were randomly assigned to receive either immediate FAP training or training after a waitlist period. Significant and large effects of training were found on both self-reported and observer-assessed measures for the first training group, and the waitlist training group replicated the first training group with significant within-subject change over the course of training. Finally, qualitative feedback from therapists indicated high satisfaction with the primary elements of the training protocol. Several important limitations to this preliminary study are discussed.

Cell-free fetal DNA testing: a pilot study of obstetric healthcare provider attitudes toward clinical implementation.

To provide a preliminary assessment of obstetric healthcare provider opinions surrounding implementation of cell-free fetal DNA testing. A 37-question pilot survey was used to address questions around the translation and use of non-invasive prenatal testing using cell-free fetal DNA. The survey was distributed and collected at a Continuing Medical Education course on obstetrics and gynecology. Of 62 survey respondents, 73% were female and 87% held MD/DO degrees. Respondents generally agreed that patients want prenatal diagnostic information to help make decisions about a pregnancy and that cell-free fetal DNA testing would encourage the testing of more patients for more conditions. However, there was an overall lack of knowledge or conviction about using this technology. Genetic counseling and professional society approval were deemed important to implementation, whereas the possibility of direct-to-consumer testing and government regulation produced mixed responses. Respondents indicated that they would be more likely to offer cell-free fetal DNA testing for chromosomal abnormalities and single-gene disorders, but would be cautious with respect to determination of sex and behavioral or late-onset conditions. Preliminary assessment indicates uncertainty among obstetric providers about the details of implementing cell-free fetal DNA testing and suggests expanded research on perspectives of this stakeholder group.

Basic technical and economic examinations of Austrian mass waste landfills, concerning the recovery of secondary raw materials, have been carried out by the 'LAMIS - Landfill Mining Austria' pilot project for the first time in Austria. A main focus of the research - the subject of this article - was the first devotion of a pilot landfill to an integrated ecological and economic assessment so that its feasibility could be verified before a landfill mining project commenced. A Styrian mass waste landfill had been chosen for this purpose that had been put into operation in 1979 and received mechanically-biologically pre-treated municipal waste till 2012. The whole assessment procedure was divided into preliminary and main assessment phases to evaluate the general suitability of a landfill mining project with little financial and human resource expense. A portfolio chart, based on a questionnaire, was created for the preliminary assessment that, as a result, has provided a recommendation for subsequent investigation - the main assessment phase. In this case, specific economic criteria were assessed by net present value calculation, while ecological or socio-economic criteria were rated by utility analysis, transferring the result into a utility-net present value chart. In the case of the examined pilot landfill, assessing the landfill mining project produced a higher utility but a lower net present value than a landfill leaving-in for aftercare. Since no clearly preferable scenario could be identified this way, a cost-revenue analysis was carried out in addition that determined a dimensionless ratio: the 'utility - net present value quotient' of both scenarios. Comparing this quotient showed unmistakably that in the overall assessment, 'leaving the landfill in aftercare' was preferable to a 'landfill mining project' in that specific case. © The Author(s) 2016.

This work is a part of LIFE+ AGROCLIMAWATER project and the aim is to improve the water efficiency, increase the adaptive capacity of tree corps and save water, in a Mediterranean area, under different climatic conditions and agricultural practices. The experimental design as well as preliminary results at farm and river basin scales are presented in this work. Specifically, ten (10) pilot farms, both organic and conventional ones have been selected in the sub-basin of Platanias in western Crete - Greece. These ten pilot farms were selected representing the most typical crops in Platanias area (olive trees and citrus trees), as well as the typical soil, landscape and agricultural practices differentiation for each crop (field slope, water availability, soil type, management regime). From the ten pilot farms, eight were olive farms and the rest two citrus. This proportion correspond adequacy to the presentence of olive and citrus crops in the extended area of Platanias prefecture. Each of the ten pilot farm has been divided in two parts, the first one will be used as a control part, while the other one as the demonstration part where the interventions will be applied. The action plans for each selected farm are based on the following groups of possible interventions: a) reduction of water evaporation losses from soil surface, b) reduction of transpiration water losses through winter pruning and summer pruning, c) reduction of deep percolation water and nutrient losses, d) reduction of surface runoff, e) measures in order to maximize the efficiency of irrigation and f) rationalization of fertilizers and agrochemicals utilized. Preliminary results indicate that water saving and crop yield can be significantly improved based on the above innervations both at farm and river basin scale.

The Short-Term Assessment of Risk and Treatability: Adolescent Version (START:AV) is a new structured professional judgment guide for assessing short-term risks in adolescents. The scheme may be distinguished from other youth risk assessment and treatment planning instruments by its inclusion of 23 dynamic factors that are each rated for both vulnerability and strength. In addition, START:AV is also unique in that it focuses on multiple adverse outcomes—namely, violence, self-harm, suicide, unauthorized leave, substance abuse, self-neglect, victimization, and general offending—over the short-term (i.e., weeks to months) rather than long-term (i.e., years). This paper describes a pilot implementation and preliminary evaluation of START:AV in three secure juvenile correctional facilities in the southern United States. Specifically, we examined the descriptive characteristics and psychometric properties of START:AV assessments completed by 21 case managers on 291 adolescent offenders (250 boys and 41 girls) at the time of admission. Results provide preliminary support for the feasibility of completing START:AV assessments as part of routine practice. Findings also highlight differences in the characteristics of START:AV assessments for boys and girls and differential associations between the eight START:AV risk domains. Though results are promising, further research is needed to establish the reliability and validity of START:AV assessments completed in the field. PMID:23316116

This study evaluated a culturally relevant, social cognitive theory-based, Internet-enhanced physical activity (PA) pilot intervention developed for overweight/obese African American (AA) female college students. Using a 3-month, single group, pretest-posttest design, participants accessed a culturally relevant PA promotion website and engaged in four moderate-intensity PA sessions each week. Study completers (n = 25, mean age = 21.9 years) reported a decrease in sedentary screen time (p < .0001); however, no changes in moderate-to-vigorous PA were reported (p = .150). A significant increase in self-regulation for PA (p < .0001) and marginally significant increases in social support (p = .052) and outcome expectations (p = .057) for PA were observed. No changes in body mass index (p = .162), PA enjoyment (p = .151), or exercise self-efficacy (p = .086) were reported. Findings of this exploratory study show some preliminary support for Internet-enhanced approaches to promote PA among overweight/obese AA women. Future studies with larger samples are needed to further explore culturally relevant Internet-enhanced PA programs in this underserved population. © The Author(s) 2014.

An alternating treatments design compared one condition in which a child with autism was allowed to engage in stereotypy freely prior to the intervention (abolishing operation component) to a second condition without the free-access period. Levels of stereotypy and problem behavior were lower and levels of functional play were higher in the condition with the abolishing operation component. These data provide preliminary support for the use of abolishing operations in interventions to increase the play skills of children with autism. PMID:20514199

This hypothesis is based on the fact that oral presentations in the context of engineering education could be used not only to develop oral communication skills but also to augment the professionalism in the curriculum. The methodological innovation is first described, which allows encouraging the capacity of summarising ideas, teamwork, assertiveness, listening skills and constructive criticism. Second, the preliminary results from two pilot groups of students during two academic years are analysed. Finally, the paper reflects on the possibilities of expanding this method to pre-university studies.

Empathy is a key aspect of the clinical encounter but there is a lack of patient-assessed measures suitable for general clinical settings. Our aim was to develop a consultation process measure based on a broad definition of empathy, which is meaningful to patients irrespective of their socio-economic background. Qualitative and quantitative approaches were used to develop and validate the new measure, which we have called the consultation and relational empathy (CARE) measure. Concurrent validity was assessed by correlational analysis against other validated measures in a series of three pilot studies in general practice (in areas of high or low socio-economic deprivation). Face and content validity was investigated by 43 interviews with patients from both types of areas, and by feedback from GPs and expert researchers in the field. The initial version of the new measure (pilot 1; high deprivation practice) correlated strongly (r = 0.85) with the Reynolds empathy measure (RES) and the Barrett-Lennard empathy subscale (BLESS) (r = 0.63), but had a highly skewed distribution (skew -1.879, kurtosis 3.563). Statistical analysis, and feedback from the 20 patients interviewed, the GPs and the expert researchers, led to a number of modifications. The revised, second version of the CARE measure, tested in an area of low deprivation (pilot 2) also correlated strongly with the established empathy measures (r = 0.84 versus RES and r = 0.77 versus BLESS) but had a less skewed distribution (skew -0.634, kurtosis -0.067). Internal reliability of the revised version was high (Cronbach's alpha 0.92). Patient feedback at interview (n = 13) led to only minor modification. The final version of the CARE measure, tested in pilot 3 (high deprivation practice) confirmed the validation with the other empathy measures (r = 0.85 versus RES and r = 0.84 versus BLESS) and the face validity (feedback from 10 patients). These preliminary results support the validity and reliability of the CARE measure as a tool for measuring patients' perceptions of relational empathy in the consultation.

To test two interventions to reduce interleukin (IL)-6 levels, an indicator of low-grade chronic inflammation and an independent risk factor for impaired mobility and slow walking speed in older adults. The ENabling Reduction of low-Grade Inflammation in SEniors (ENRGISE) Pilot Study was a multicenter, double-blind, placebo-controlled randomized pilot trial of two interventions to reduce IL-6 levels. Five university-based research centers. Target enrollment was 300 men and women aged 70 and older with an average plasma IL-6 level between 2.5 and 30 pg/mL measured twice at least 1 week apart. Participants had low to moderate physical function, defined as self-reported difficulty walking one-quarter of a mile or climbing a flight of stairs and usual walk speed of less than 1 m/s on a 4-m usual-pace walk. Participants were randomized to losartan, omega-3 fish oil (ω-3), combined losartan and ω-3, or placebo. Randomization was stratified depending on eligibility for each group. A titration schedule was implemented to reach a dose that was safe and effective for IL-6 reduction. Maximal doses were 100 mg/d for losartan and 2.8 g/d for ω-3. IL-6, walking speed over 400 m, physical function (Short Physical Performance Battery), other inflammatory markers, safety, tolerability, frailty domains, and maximal leg strength were measured. Results from the ENRGISE Pilot Study will provide recruitment yields, feasibility, medication tolerance and adherence, and preliminary data to help justify a sample size for a more definitive randomized trial. The ENRGISE Pilot Study will inform a larger subsequent trial that is expected to have important clinical and public health implications for the growing population of older adults with low-grade chronic inflammation and mobility limitations. © 2017, Copyright the Authors Journal compilation © 2017, The American Geriatrics Society.

Rationales for home safety promotion in the Iranian primary healthcare system: results from a pilot study.

To analyse the prerequisites for a nationwide primary healthcare (PHC) home safety promotion programme in Iran. Injury is a major public health problem throughout the world, currently accounting for one-seventh of all premature deaths and disabilities. Within 20 years, it is estimated that the proportion will increase to one-fifth. The present healthcare system in Iran was started in 1979, with a major focus on easy access to services and prevention. The system is based on the 'health house', which is run by community health workers. A survey shows that 36% of injuries occur in the home environment. A pilot phase of the Home Safety Promotion Programme was initiated in 1994, and included safety checking at home for fences, kitchens, drugs and poisons, heaters, electricity, and stairs and ladders. The pilot study covered 478,551 households out of the 12 million (approximately) in Iran. Sixty-nine supervisors were involved individually, assembled into eight focus groups. Household safety increased by 10-20% over the 4 years of the study. The frequency of home visits changed from annual to seasonal, since all participants agreed that there were seasonal differences in safety problems. The supervisors showed a high level of knowledge of injury as a public health problem, and also positive attitudes towards doing something about safety on the basis of a PHC scheme. The role of a surveillance system was highlighted, and it was suggested that such a system should be added to the programme. Based on our preliminary findings, there were reasons to obtain a policy decision concerning a national programme for safety promotion before extending the pilot scheme to the whole country. A national safety programme was decided upon following completion of the pilot study. It includes a home-related-injury surveillance system that is mandatory in rural areas and voluntary in some cities.

Cultural adaptation of evidence-based programmes has gained importance primarily owing to its perceived impact on the established effectiveness of a programme. To date, many researchers have proposed different frameworks for systematic adaptation process. This article presents the cultural adaptation of preschool Promoting Alternative Thinking Strategies (PATHS) curriculum for Pakistani children using the heuristic framework of adaptation (Barrera & Castro, 2006). The study was completed in four steps: information gathering, preliminary adaptation design, preliminary adaptation test and adaptation refinement. Feedbacks on programme content suggested universality of the core programme components. Suggested changes were mostly surface structure: language, presentation of materials, conceptual equivalence of concepts, training needs of implementation staff and frequency of programme delivery. In-depth analysis was done to acquire cultural equivalence. Pilot testing of the outcome measures showed strong internal consistency. The results were further discussed with reference to similar work undertaken in other cultures. © 2014 International Union of Psychological Science.

Preliminary Validation of the Small Aircraft Transportation System Higher Volume Operations (SATS HVO) Concept

NASA Technical Reports Server (NTRS)

Williams, Daniel; Consiglio, Maria; Murdoch, Jennifer; Adams, Catherine

2004-01-01

This document provides a preliminary validation of the Small Aircraft Transportation System (SATS) Higher Volume Operations (HVO) concept for normal conditions. Initial results reveal that the concept provides reduced air traffic delays when compared to current operations without increasing pilot workload. Characteristic to the SATS HVO concept is the establishment of a newly defined area of flight operations called a Self-Controlled Area (SCA) which would be activated by air traffic control (ATC) around designated non-towered, non-radar airports. During periods of poor visibility, SATS pilots would take responsibility for separation assurance between their aircraft and other similarly equipped aircraft in the SCA. Using onboard equipment and simple instrument flight procedures, they would then be better able to approach and land at the airport or depart from it. This concept would also require a new, ground-based automation system, typically located at the airport that would provide appropriate sequencing information to the arriving aircraft. Further validation of the SATS HVO concept is required and is the subject of ongoing research and subsequent publications.

The feasibility and preliminary efficacy of an android robot-mediated mock job interview training in terms of both bolstering self-confidence and reducing biological levels of stress in comparison to a psycho-educational approach human interview was assessed in a randomized study. Young adults (ages 18–25 years) with autism spectrum disorder (ASD) were randomized to participate either in a mock job interview training with our android robot system (n = 7) or a self-paced review of materials about job-interviewing skills (n = 8). Baseline and outcome measurements of self-reported performance/efficacy and salivary cortisol were obtained after a mock job interview with a human interviewer. After training sessions, individuals with ASD participating in the android robot-mediated sessions reported marginally improved self-confidence and demonstrated significantly lower levels of salivary cortisol as compared to the control condition. These results provide preliminary support for the feasibility and efficacy of android robot-mediated learning. PMID:28955254

Mindfulness meditation training is garnering increasing empirical interest as an intervention for ADHD in adulthood, although no studies of mindfulness as a standalone treatment have included a sample composed entirely of adults with ADHD or a comparison group. The aim of this study was to assess the feasibility, acceptability, and preliminary efficacy of mindfulness meditation for ADHD, executive functioning (EF), and emotion dysregulation symptoms in an adult ADHD sample. Adults with ADHD were stratified by ADHD medication status and otherwise randomized into an 8-week group-based mindfulness treatment ( n = 11) or waitlist group ( n = 9). Treatment feasibility and acceptability were positive. In addition, self-reported ADHD and EF symptoms (assessed in the laboratory and ecological momentary assessment), clinician ratings of ADHD and EF symptoms, and self-reported emotion dysregulation improved for the treatment group relative to the waitlist group over time with large effect sizes. Improvement was not observed for EF tasks. Findings support preliminary treatment efficacy, though require larger trials.

The purpose of this study was to evaluate the feasibility of implementing a video-module-based mindfulness pilot program intended to reduce stress, improve well-being, and develop mindfulness skills in physicians in a community hospital setting. Preliminary findings are presented. Using a single-sample, pre-post study design, we administered an eight-week mindfulness training offered as part of a wellness initiative for medical staff in a suburban community hospital. Participants enrolled on a first-come, first-served basis. Participants engaged in three 90-min in-person trainings, weekly online video-module trainings, and weekly teleconference coaching calls. Video-module trainings were available at all times, to be accessed at the participants׳ convenience. Journals and a guided meditation audio library were also provided. Physician stress, well-being (emotional exhaustion, depersonalization of patients, and sense of personal accomplishment), and mindfulness skills (observing, describing, acting with awareness, and accepting without judgment) were evaluated at baseline, end-of-program, and eight weeks post-intervention using well-validated instruments. A total of 23 physicians enrolled and 19 completed the program. Compared to baseline, statistically significant decreases in stress, personal accomplishment, and emotional exhaustion were observed at end-of-program and eight weeks post-intervention (all P < .05). Significant increases in all mindfulness skills were observed at end-of-program; these increases persisted for describing, acting with awareness, and accepting without judgment at eight weeks post-intervention (all P < .05). This study provides preliminary evidence that a flexible, video-module-based mindfulness program can decrease stress, increase well-being, and develop lasting mindfulness skills in physicians.

We evaluated the feasibility of asking pregnant women to self-collect and ship respiratory specimens. In a preliminary laboratory study, we compared the RT-PCR cycle threshold (CT) values of influenza A and B viruses incubated at 4 storage temperatures (from 4 to 35°C) for 6 time periods (8, 24, 48, 72, and 168 hours and 30 days), resulting in 24 conditions that were compared to an aliquot tested after standard freezing (-20°C) (baseline condition). In a subsequent pilot study, during January-February, 2014, we delivered respiratory specimen collection kits to 53 pregnant women with a medically attended acute respiratory illness using three delivery methods. CT values were stable after storage at temperatures <27°C for up to 72 hours for influenza A viruses and 48 hours for influenza B viruses. Of 53 women who received kits during the pilot, 89% collected and shipped nasal swabs as requested. However, 30% (14/47) of the women took over 2 days to collect and ship their specimen. The human control gene, ribonuclease P (RNase P), was detected in 100% of nasal swab specimens. However, the mean CT values for RNase P (26.5, 95% confidence interval [CI] = 26.0-27.1) and for the 8 influenza A virus positives in our pilot (32.2, 95% CI = 28.9-35.5) were significantly higher than the CTs observed in our 2010-2012 study using staff-collected nasal pharyngeal swabs (P-values < 0.01). Self-collection of respiratory specimens is a promising research method, but further research is needed to quantify the sensitivity and specificity of the approach. © 2015 The Authors.

Patients with severe pulmonary arterial hypertension (PAH) in New York Heart Association (NYHA) functional class (FC) III/IV have a poor prognosis, despite survival benefits being demonstrated with intravenous epoprostenol. In this pilot study, the efficacy and safety of a triple combination therapy regimen in patients with severe PAH was investigated. Data from newly diagnosed NYHA FC III/IV PAH patients (n=19) initiated on upfront triple combination therapy (intravenous epoprostenol, bosentan and sildenafil) were collected retrospectively from a prospective registry. Significant improvements in 6-min walk distance and haemodynamics were observed after 4 months' triple combination therapy in 18 patients (p<0.01); 17 patients had improved to NYHA FC I or II. One patient was not included in the month 4 assessment (due to an emergency lung transplant in month 3). At the final evaluation (mean ± sd 32 ± 19 months), all 18 patients had sustained clinical and haemodynamic improvement. Overall survival estimates for the triple combination cohort were 100% at 1, 2 and 3 years. Expected survival calculated from the French equation was 75% (95% CI 68-82%), 60% (95% CI 50-70%) and 49% (95% CI 38-60%) at 1, 2 and 3 years, respectively. This pilot study provides preliminary evidence of the long-term benefits of upfront triple combination therapy in patients with severe PAH. ©ERS 2014.

COPD places an enormous burden on the healthcare systems and causes diminished health-related quality of life. The highest proportion of human and economic cost is associated with admissions for acute exacerbation of respiratory symptoms (AECOPD). Since prompt detection and treatment of exacerbations may improve outcomes, early detection of AECOPD is a critical issue. This pilot study was aimed to determine whether a mobile health system could enable early detection of AECOPD on a day-to-day basis. A novel electronic questionnaire for the early detection of COPD exacerbations was evaluated during a 6-months field trial in a group of 16 patients. Pattern recognition techniques were applied. A k-means clustering algorithm was trained and validated, and its accuracy in detecting AECOPD was assessed. Sensitivity and specificity were 74.6 and 89.7 %, respectively, and area under the receiver operating characteristic curve was 0.84. 31 out of 33 AECOPD were early identified with an average of 4.5 ± 2.1 days prior to the onset of the exacerbation that was considered the day of medical attendance. Based on the findings of this preliminary pilot study, the proposed electronic questionnaire and the applied methodology could help to early detect COPD exacerbations on a day-to-day basis and therefore could provide support to patients and physicians.

Specialized treatment for first episode psychosis offers clients a menu of services coordinated within a specialized treatment team. To enhance the impact of these services, promoting engagement and preventing early treatment drop-out is critical. However, engagement is poorly tracked and typically quantified through proxy variables such as session attendance, medication adherence, or working alliance. The aim of this study is to introduce and pilot a new measure of engagement for first episode psychosis coordinated specialty care, the Client Engagement and Service Use Scale (CENSUS). The CENSUS was evaluated for reliability and validated against the Service Engagement Scale and an appointment count for a small sample (N = 10) of first episode clients. The measure was also evaluated for acceptability by a consumer advocacy group. Clinicians achieved high inter-rater reliability after minimal training. CENSUS items demonstrated medium to large correlations with other measures of engagement. Feedback from the consumer group emphasized that clinicians should ask questions in a way that is nonjudgmental and successfully elicits authentic client feedback about their service preferences. This pilot study yielded preliminary evidence of reliability and validity, suggesting that the CENSUS is a useful and novel tool for tracking and differentiating degrees of client engagement across multiple intervention components and for facilitating structured discussions regarding clients' service utilization and preferences.

This pilot study assessed the feasibility, efficacy and safety of an individual dose-titration approach, and of the intravenous (IV), intramuscular (IM) and subcutaneous (SC) routes for treating depression with ketamine. Fifteen treatment-refractory depressed participants received ketamine or midazolam (control treatment) in a multiple crossover, double-blind study. Ketamine was administered by IV (n = 4), IM (n = 5) or SC (n = 6) injection. Dose titration commenced at 0.1 mg/kg, increasing by 0.1 mg/kg up to 0.5 mg/kg, given in separate treatment sessions separated by ≥1 week, with one placebo control treatment randomly inserted. Mood, psychotomimetic and hemodynamic effects were assessed and plasma ketamine concentrations assayed. Twelve participants achieved response and remission criteria, achieved at doses as low as 0.1 mg/kg. All three routes of administration resulted in comparable antidepressant effects. Fewest adverse effects were noted with the SC route. Antidepressant response, adverse effects and ketamine concentrations were dose-related. Antidepressant response occurred at a range of doses and at <0.5 mg/kg. The dose-titration approach is a practical method for optimizing the efficacy - side-effects trade-off on an individual patient basis. This pilot study provides preliminary evidence for SC injection as a practical, feasible and efficacious treatment approach. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

PILOT (Polarized Instrument for the Long-wavelength Observations of the Tenuous ISM), is a balloon-borne astronomy experiment dedicated to study the polarization of dust emission from the diffuse ISM in our Galaxy [1]. The observations of PILOT have two major scientific objectives. Firstly, they will allow us to constrain the large-scale geometry of the magnetic field in our Galaxy and to study in details the alignment properties of dust grains with respect to the magnetic field. In this domain, the measurements of PILOT will complement those of the Planck satellite at longer wavelengths. In particular, they will bring information at a better angular resolution, which is critical in crowded regions such as the Galactic plane. They will allow us to better understand how the magnetic field is shaping the ISM material on large scale in molecular clouds, and the role it plays in the gravitational collapse leading to star formation. Secondly, the PILOT observations will allow us to measure for the first time the polarized dust emission towards the most diffuse regions of the sky, where the measurements are the most easily interpreted in terms of the physics of dust. In this particular domain, PILOT will play a role for future CMB missions similar to that played by the Archeops experiment for Planck. The results of PILOT will allow us to gain knowledge about the magnetic properties of dust grains and about the structure of the magnetic field in the diffuse ISM that is necessary to a precise foreground subtraction in future polarized CMB measurements. The PILOT measurements, combined with those of Planck at longer wavelengths, will therefore allow us to further constrain the dust models. The outcome of such studies will likely impact the instrumental and technical choices for the future space missions dedicated to CMB polarization. The PILOT instrument will allow observations in two photometric channels at wavelengths 240 μm and 550 μm, with an angular resolution of a few arcminutes. We will make use of large format bolometer arrays, developed for the PACS instrument on board the Herschel satellite. With 1024 detectors per photometric channel and photometric band optimized for the measurement of dust emission, PILOT is likely to become the most sensitive experiment for this type of measurements. The PILOT experiment will take advantage of the large gain in sensitivity allowed by the use of large format, filled bolometer arrays at frequencies more favorable to the detection of dust emission. This paper presents the optical design, optical characterization and its performance. We begin with a presentation of the instrument and the optical system and then we summarise the main optical tests performed. In section III, we present preliminary end-to-end test results.

Chemical Processing of Organics within Clouds: Pilot Study at Whiteface Mountain in Upstate NY

Aqueous chemical processing within cloud and fog water has been identified as a key process in the formation of secondary organic aerosol (SOA) mass, which is found abundantly throughout the troposphere. Yet, significant uncertainty remains regarding the organic chemical reactions taking place within clouds and the conditions under which those reactions occur. Routine longterm measurements from the Whiteface Mountain (WFM) Research Observatory in upstate NY provide a unique and broad view of regional air quality relevant to the formation of particulate matter within clouds, largely due to the fact that the summit of WFM is within non-precipitating clouds 30-50% in summertime and the site is undisturbed by local sources. An NSF-funded Cloud Chemistry Workshop in Sept 2016 brought together key researchers at WFM to lay out the most pertinent scientific questions relevant to heterogeneous chemistry occurring within fogs and clouds and to discuss preliminary model intercomparisons. The workshop culminated in a plan to coordinate chemical analyses of cloud water samples focused on chemical constituents thought to be most relevant for SOA formation. Workshop participants also recommended that a pilot study be conducted at WFM to better characterize the meteorological conditions, airflow patterns and clouds intercepting the site, in preparation for future intensive field operations focused on the chemical processing of organics within clouds. This presentation will highlight the experimental design and preliminary observations from the pilot study taking place at WFM in August 2017. Upwind below-cloud measurements of aerosol CCN activation efficiency, size distribution and chemical composition will be compared with similar measurements made at the summit. Under certain conditions, we anticipate that aerosols measured at the summit between cloud events will be representative of cloud droplet residuals recently detrained from the frequent shallow cumulus intercepting the summit. Wind LIDAR and radiosonde observations will be used to link the below-cloud and summit observations. These pre- and post- `cloud processed' aerosols will also be compared with the chemical composition of cloud water samples to evaluate changes to the organic partitioning in the aqueous and aerosol phases.

Daily personal exposure to black carbon: A pilot study

Continuous personal monitoring is the benchmark for air pollution exposure assessment. Black carbon (BC) is a strong marker of primary combustion like vehicle and biomass emissions. There have been few studies that quantified daily personal BC exposure and the contribution that different microenvironments make to it. In this pilot study, we used a portable aethalometer to measure BC concentrations in an individual's breathing zone at 30-s intervals while he performed his usual daily activities. We used a GPS and time-activity diary to track where he spent his time. We performed twenty 24-h measurements, and observed an arithmetic mean daily exposure concentration of 603 ng/m3. We estimated that changing commute modes from bus to train reduced the 24-h mean BC exposure concentration by 29%. Switching from open windows to closed windows and recirculated air in a car led to a reduction of 32%. Living in a home without a wood-fired heater caused a reduction of 50% compared with a wood-heated home. Our preliminary findings highlight the potential utility of simple approaches to reduce a person's daily BC exposure.

The aim of this prospective pilot study was to evaluate the prosthodontic maintenance as well as the implant outcome of single implant-retained mandibular overdentures over an observation period of 6 years. Eleven edentulous patients received one single implant in the midline of the mandible. Denture bases were temporarily relined and 2 months later provided with a ball attachment for implant retention. Implant related parameters and prosthodontic maintenance interventions were assessed 4 weeks after implant loading and then once a year. Over a mean observation period of 75.9 months, no implant was lost. The most frequent prosthetic maintenance intervention was activation of the matrix due to loss of retention, followed by exchange of the female part. Eight denture bases had to be repaired after a fracture in the midline area. Within the limitations of this preliminary clinical study, the concept of a single midline implant to retain a mandibular complete denture was a successful treatment option for elderly edentulous patients. © 2014 John Wiley & Sons A/S.

2013-03-01

To address the speeding problem in residential areas, the City of Edmonton initiated a pilot project to reduce the posted speed limit from 50km/h to 40km/h within six residential communities. This paper investigates the community perceptions of traffic safety within the six pilot communities in two phases: prior to project initiation (pre-pilot) and following the end of the project (post-pilot). This objective was accomplished by analyzing the results of two random dialing telephone surveys comprising 300 residents each. A preliminary analysis showed compatible demographic configurations for the two samples and confirmed that the residents were aware of both the posted speed limits and the adopted speed management controls. For the confirmatory factor analysis (CFA), a two-group (pre-pilot and post-pilot) three-factor model was used to assess the residents' perceptions of the speeding behavior (Speeding), their concerns about traffic safety issues (Concerns), and their perceptions of traffic safety (Safety). Comparing the CFA results of the post-pilot survey versus those of the pre-pilot survey, it was evident that there was a significant decrease in Speeding and Concerns accompanied by a significant increase in Safety. A structural equations model (SEM) was also fitted to the data in order to assess the impact of Speeding and Concerns on Safety. The results showed that Concerns increase significantly with Speeding, and that both factors have significant negative impacts on Safety. However, while the impact of Concerns on Safety was direct, that of Speeding on Safety was largely indirect (i.e., mediated through Concerns). Overall, the multivariate analysis has demonstrated that the pilot project was successful in improving the residents' perceptions of traffic safety in their community. Crown Copyright © 2012.

2010-01-01

Background Existing questionnaires to assess barriers against consultation for urinary incontinence (UI) are not appropriate for use in the Middle East culture. The aim of this study was to explore barriers against seeking help for UI and introducing a questionnaire that assess these barriers among those women. This is important before proceeding to any educational programs or having interval clinical audits to help incontinent women. Methods 1- Screening for UI. Women - aged 20 years and older, attending the outpatient Urology and Gynaecology clinics were invited to participate and interviewed by a research nurse. The UDI-6 was administered to assess the presence and type of UI. Women with UI as their chief complaint were excluded. 2- Interviewing study subjects for possible barriers. Subjects who had UI - as determined by the UDI-6-were first asked an open question "what prevented you from seeking medical consultation for urine leakage?"." They were then asked the proposed questions to assess possible barriers. We developed a preliminary questionnaire based on a review of reasons for not seeking incontinence care from the literature and the response of UI sufferers to the open question in this study. The questionnaire was modified many times to reach this final form. 3- Pilot Study to assess characteristics of the questionnaire. Validity and reliability of the final version of the questionnaire were assessed in a small pilot study including 36 women who completed questionnaire at initial visit and again after 2 weeks. Results Of the 1231 subjects who agreed to participate in the study, 348 reported having UI. About 80% of incontinent women have never sought medical advice. Factors significantly associated with seeking help were husband encouragement, prayer affection and having severe UI. Common barriers were embarrassment and assuming UI as a normal part of aging. A pilot study included 36 women to assess the psychometric properties of the questionnaire after modifying it. The number of missing or not interpretable responses per item ranged from 2.2% to 8.7%. Internal consistency of the items was good. The test-retest reliability of individual items of the questionnaire was variable, with weighted kappa statistics ranging from 0.32 to 0.94 (median, 0.76, p 0.000). Conclusions Preliminary data on our proposed questionnaire show that it is an easy to administer, stable and suits the Middle Eastern culture. PMID:20105307

Adaptive interface devices make it possible for individuals with physical disabilities to use microcomputers and thus perform many tasks that they would otherwise be unable to accomplish. Special equipment is available that purports to allow functional access to the computer for users with disabilities. As technology moves from purely keyboard applications to include graphic input, it will be necessary for assistive interface devices to support graphics as well as text entry. Headpointing systems that emulate the mouse in combination with on-screen keyboards are of particular interest to persons with severe physical impairment such as high level quadriplegia. Two such systems currently on the market are the HeadMaster and the Free Wheel. The authors have conducted a pilot study comparing graphic input speed using the mouse and two headpointing interface systems on the Macintosh computer. The study used a single subject design with six able-bodied subjects, to establish a baseline for comparison with persons with severe disabilities. Results of these preliminary data indicated that the HeadMaster was nearly as effective as the mouse and that it was superior to the Free Wheel for graphics input. This pilot study, however, demonstrated several experimental design problems that need to be addressed to make the study more robust. It also demonstrated the need to include the evaluation of text input so that the effectiveness of the interface devices with text and graphic input could be compared.

Cardiovascular disease (CVD) is markedly increased among hemodialysis (HD) patients. Optimizing blood pressure (BP) among HD patients may present an important opportunity to reduce the disparity in CVD rates between HD patients and the general population. The optimal target predialysis systolic BP (SBP) among HD patients is unknown. Current international guidelines, calling for a predialysis SBP < 140 mm Hg, are based on the opinion and extrapolation from the general population. Existing randomized controlled trials (RCTs) were small and did not include prespecified BP targets. The authors described the design of the Blood Pressure in Dialysis (BID) Study, a pilot, multicenter RCT where HD patients are randomized to either a target-standardized predialysis SBP of 110 to 140 mm Hg or 155 to 165 mm Hg. This is the first study to randomize HD patients to 2 different SBP targets. Primary outcomes are feasibility and safety. Feasibility parameters include recruitment and retention rates, adherence with prescribed BP measurements and achievement and maintenance of selected BP targets. Safety parameters include rates of hypotension and other adverse and serious adverse events. The authors obtained preliminary data on changes in left ventricular mass, aortic pulse wave velocity, vascular access thromboses and health-related quality of life across study arms, which may be the secondary outcomes in the full-scale study. The data acquired in the pilot RCT will determine the feasibility and safety and inform the design of a full-scale trial, powered for hard outcomes, which may require 2000 participants.

Safety Performance of Airborne Separation: Preliminary Baseline Testing

The Safety Performance of Airborne Separation (SPAS) study is a suite of Monte Carlo simulation experiments designed to analyze and quantify safety behavior of airborne separation. This paper presents results of preliminary baseline testing. The preliminary baseline scenario is designed to be very challenging, consisting of randomized routes in generic high-density airspace in which all aircraft are constrained to the same flight level. Sustained traffic density is varied from approximately 3 to 15 aircraft per 10,000 square miles, approximating up to about 5 times today s traffic density in a typical sector. Research at high traffic densities and at multiple flight levels are planned within the next two years. Basic safety metrics for aircraft separation are collected and analyzed. During the progression of experiments, various errors, uncertainties, delays, and other variables potentially impacting system safety will be incrementally introduced to analyze the effect on safety of the individual factors as well as their interaction and collective effect. In this paper we report the results of the first experiment that addresses the preliminary baseline condition tested over a range of traffic densities. Early results at five times the typical traffic density in today s NAS indicate that, under the assumptions of this study, airborne separation can be safely performed. In addition, we report on initial observations from an exploration of four additional factors tested at a single traffic density: broadcast surveillance signal interference, extent of intent sharing, pilot delay, and wind prediction error.

Despite being the most commonly used herbal for sleep disorders, chamomile's (Matricaria recutita) efficacy and safety for treating chronic primary insomnia is unknown. We examined the preliminary efficacy and safety of chamomile for improving subjective sleep and daytime symptoms in patients with chronic insomnia. We performed a randomized, double-blind, placebo-controlled pilot trial in 34 patients aged 18-65 years with DSM-IV primary insomnia for ≥ 6-months. Patients were randomized to 270 mg of chamomile twice daily or placebo for 28-days. The primary outcomes were sleep diary measures. Secondary outcomes included daytime symptoms, safety assessments, and effect size of these measures. There were no significant differences between groups in changes in sleep diary measures, including total sleep time (TST), sleep efficiency, sleep latency, wake after sleep onset (WASO), sleep quality, and number of awakenings. Chamomile did show modest advantage on daytime functioning, although these did not reach statistical significance. Effect sizes were generally small to moderate (Cohen's d ≤ 0.20 to < 0.60) with sleep latency, night time awakenings, and Fatigue Severity Scale (FSS), having moderate effect sizes in favor of chamomile. However, TST demonstrated a moderate effect size in favor of placebo. There were no differences in adverse events reported by the chamomile group compared to placebo. Chamomile could provide modest benefits of daytime functioning and mixed benefits on sleep diary measures relative to placebo in adults with chronic primary insomnia. However, further studies in select insomnia patients would be needed to investigate these conclusions.

The major aspects of this project are proceeding toward completion. Prior to this quarter, design criteria, tentative site selection, facility layout, and preliminary facility cost estimates were completed and issued. Processing of bio-solids was completed, providing material for the pilot operations. Pilot facility design, equipment selection, and modification were completed during the fourth quarter of 2000. Initial pilot facility shakedown was completed during the fourth quarter. After some unavoidable delays, a suitable representative supply of MSW feed material was procured. During this first quarter of 2001, shredding of the feed material and final feed conditioning were completed. Pilot facility hydrolysismore » production was completed to produce lignin for co-fire testing. During this quarter, TVA completed the washing and dewatering of the lignin material produced from the MSW hydrolysis. Seven drums of lignin material were washed to recover the acid and sugar from the lignin and provide an improved fuel for steam generation. Samples of both the lignin and bio-solids fuel materials for co-fire testing were sent to the co-fire facility (EERC) for evaluation. After sample evaluation, EERC approved sending the material and all of the necessary fuel for testing was shipped to EERC. EERC has requested and will receive coal typical of the fuel to the TVA-Colbert boilers. This material will be used at EERC as baseline material and for mixing with the bio-fuel for combustion testing. EERC combustion testing of the bio based fuels is scheduled to begin in August of 2001. The TVA-Colbert facility has neared completion of the task to evaluate the co-location of the Masada facility on the operation of the power generation facility. The TVA-Colbert fossil plant is fully capable of providing a reliable steam supply. The preferred steam supply connection points and steam pipeline routing have been identified. The environmental review of the pipeline routing has been completed and no major impacts have been identified. Detailed assessment of steam export impacts on the Colbert boiler system have been completed and a cost estimate for steam supply system was completed. The cost estimate and the output and heat rate impacts will be used to determine a preliminary price for the exported steam. The preliminary steam price will be determined in the next quarter.« less

People who have a transient ischaemic attack (TIA) or minor stroke are at high risk of a recurrent stroke, particularly in the first week after the event. Early initiation of secondary prevention drugs is associated with an 80% reduction in risk of stroke recurrence. This raises the question as to whether these drugs should be given before being seen by a specialist--that is, in primary care or in the emergency department. The aims of the RAPID-TIA pilot trial are to determine the feasibility of a randomised controlled trial, to analyse cost effectiveness and to ask: Should general practitioners and emergency doctors (primary care physicians) initiate secondary preventative measures in addition to aspirin in people they see with suspected TIA or minor stroke at the time of referral to a specialist? This is a pilot randomised controlled trial with a sub-study of accuracy of primary care physician diagnosis of TIA. In the pilot trial, we aim to recruit 100 patients from 30 general practices (including out-of-hours general practice centres) and 1 emergency department whom the primary care physician diagnoses with TIA or minor stroke and randomly assign them to usual care (that is, initiation of aspirin and referral to a TIA clinic) or usual care plus additional early initiation of secondary prevention drugs (a blood-pressure lowering protocol, simvastatin 40 mg and dipyridamole 200 mg m/r bd). The primary outcome of the main study will be the number of strokes at 90 days. The diagnostic accuracy sub-study will include these 100 patients and an additional 70 patients in whom the primary care physician thinks the diagnosis of TIA is possible, rather than probable. For the pilot trial, we will report recruitment rate, follow-up rate, a preliminary estimate of the primary event rate and occurrence of any adverse events. For the diagnostic study, we will calculate sensitivity and specificity of primary care physician diagnosis using the final TIA clinic diagnosis as the reference standard. This pilot study will be used to estimate key parameters that are needed to design the main study and to estimate the accuracy of primary care diagnosis of TIA. The planned follow-on trial will have important implications for the initial management of people with suspected TIA. ISRCTN62019087.

Few educational resources have been developed to inform patients' renal replacement therapy (RRT) selection decisions. Patients progressing toward end stage renal disease (ESRD) must decide among multiple treatment options with varying characteristics. Complex information about treatments must be adequately conveyed to patients with different educational backgrounds and informational needs. Decisions about treatment options also require family input, as families often participate in patients' treatment and support patients' decisions. We describe the development, design, and preliminary evaluation of an informational, evidence-based, and patient-and family-centered decision aid for patients with ESRD and varying levels of health literacy, health numeracy, and cognitive function. We designed a decision aid comprising a complementary video and informational handbook. We based our development process on data previously obtained from qualitative focus groups and systematic literature reviews. We simultaneously developed the video and handbook in "stages." For the video, stages included (1) directed interviews with culturally appropriate patients and families and preliminary script development, (2) video production, and (3) screening the video with patients and their families. For the handbook, stages comprised (1) preliminary content design, (2) a mixed-methods pilot study among diverse patients to assess comprehension of handbook material, and (3) screening the handbook with patients and their families. The video and handbook both addressed potential benefits and trade-offs of treatment selections. The 50-minute video consisted of demographically diverse patients and their families describing their positive and negative experiences with selecting a treatment option. The video also incorporated health professionals' testimonials regarding various considerations that might influence patients' and families' treatment selections. The handbook was comprised of written words, pictures of patients and health care providers, and diagrams describing the findings and quality of scientific studies comparing treatments. The handbook text was written at a 4th to 6th grade reading level. Pilot study results demonstrated that a majority of patients could understand information presented in the handbook. Patient and families screening the nearly completed video and handbook reviewed the materials favorably. This rigorously designed decision aid may help patients and families make informed decisions about their treatment options for RRT that are well aligned with their values.

The Tennessee Valley Authority (TVA) is actively engaged in a pilot plant program to develop and/or evaluate wet-scrubbing processes for removing sulfur dioxide (SO/sub 2/) from boiler flue gas. The physical size and general arrangement of flue gas scrubbing systems have a major impact on capital investment and operating cost, as do potential operating and maintenance advantages inherent to some systems. The equipment configuration for a cocurrent scrubber reflects some of these advantages. EPRI funded TVA to perform preliminary screening tests of TVA's 1 MW pilot plant (Colbert Steam Plant) to develop operating data on the cocurrent design for usemore » in designing and operating a 10 MW prototype cocurrent scrubber at TVA's Shawnee Scrubber Test Facility. Results of the Colbert tests showed excellent sulfur dioxide removal efficiencies, generally greater than 85%, low pressure drop, and high particulate removal efficiencies. This report covers these screening tests.« less

e100 NeuroRobotic system.

Therapy incorporating the repeated practice of motor tasks has been found to enhance motor function after stroke. This type of therapy may be facilitated by robotic devices and several such devices are being developed for use in rehabilitation. The Myomo e100 NeuroRobotic system is a novel device developed to provide assistance during elbow movements in stroke survivors. The device uses surface electromyographic signals to control a powered elbow orthosis. Data from a pilot study reveals that the device can be used successfully by stroke survivors and suggests that it may be effective in helping to restore motor control after stroke. Further studies are needed to confirm these preliminary results.

Neurocognitive findings in compulsive sexual behavior: a preliminary study.

PubMed

Derbyshire, Katherine L; Grant, Jon E

2015-06-01

BACKGROUND AND AIMS :Compulsive sexual behavior (CSB) is a common behavior affecting 3-6% of the population, characterized by repetitive and intrusive sexual urges or behaviors that typically cause negative social and emotional consequences. For this small pilot study on neurological data, we compared 13 individuals with CSB and gender- matched healthy controls on diagnostic assessments and computerized neurocognitive testing. No significant differences were found between the groups. These data contradict a common hypothesis that CSB is cognitively different from those without psychiatric comorbidities as well as previous research on impulse control disorders and alcohol dependence. Further research is needed to better understand and classify CSB based on these findings.

Although physiotherapists have long advocated workplace health, school teachers have not traditionally been a focus of study by these professionals. However, classroom teaching contributes to a range of occupational health issues related to general health as well as ergonomics that can be prevented or addressed by physiotherapists. To undertake a pilot study to explore the potential effects of a physiotherapy-directed occupational health programme individualised for school teachers, develop study methodology and gather preliminary data to establish a 'proof of concept' to inform future studies. Cluster randomised pilot study using a convenience sample. Eight Austrian regional secondary schools. Schools and their teachers were recruited and allocated to an intervention group (IG, n=26 teachers) or a control group (CG, n=43 teachers). Teachers were eligible to participate if they reported no health issues that compromised their classroom responsibilities. The IG participated in an individualised physiotherapy-directed occupational health programme (six 30-minute sessions) related to ergonomics and stress management conducted over a 5-month semester. The CG had a pseudo-intervention of one oral education session. Primary outcomes included scores from the physical and mental components and health transition item of the Short-Form-36 Health Survey questionnaire (SF-36), and emotional well-being and resistance to stress items from the work-related behaviour and experience patterns questionnaire. Data were collected before and after one semester. The primary outcome measure, the SF-36 physical component score, showed a reduction in the CG and no change in the IG, meaning that the CG deteriorated over the study semester while the IG did not show any change. A physiotherapy-directed occupational health programme may prevent deterioration of physical health of school teachers in one semester (proof of concept). This pilot study provided valuable information to inform the design of replication and extension studies related to this work. Copyright © 2013 Chartered Society of Physiotherapy.

Mcveigh, M. A.

1976-01-01

The feasibility of the tilt-rotor concept was verified through investigation of the performance, stability and handling qualities of the XV-15 tilt rotor. The rotors were replaced by advanced-technology fiberglass/composite hingless rotors of larger diameter, combined with an advanced integrated fly-by-wire control system. A parametric simulation model of the HRXV-15 was developed, model was used to define acceptable preliminary ranges of primary and secondary control schedules as functions of the flight parameters, to evaluate performance, flying qualities and structural loads, and to have a Boeing-Vertol pilot conduct a simulated flight test evaluation of the aircraft.

Assess the feasibility of implementing the GoActive intervention in secondary schools, to identify improvements, test study procedures, determine preliminary effectiveness to increase moderate-to-vigorous physical activity (MVPA), and inform power calculations to establish programme effectiveness. Feasibility study (1 school) and pilot cluster-randomised controlled trial (CRCT; 2 intervention; 1 control school(s)). 460 participants (46.6% female; 13.2 (0.4) years old). 8-week intervention (2013) involved: classes choosing weekly activities encouraged by mentors (older adolescents) and in-class peer leaders. Students gain points for trying activities which are entered into an intramural competition. Planned quantitative (questionnaire) and qualitative (focus groups) process evaluation addressed enjoyment, confidence, participation, suggested improvements. Outcomes were assessed at baseline and follow-up (week 8) in pilot CRCT and included accelerometer-assessed MVPA; adolescent-reported activity type, well-being, peer support, shyness, sociability. Analysis of covariance was used to assess preliminary effectiveness as change in MVPA adjusted for baseline. All year 9 students in intervention schools were exposed to the intervention; over all schools 77% of eligible students were measured. 71% boys and 74% girls found GoActive 'fun'; 38% boys and 32% girls said it increased confidence, and 64% boys and 59% girls said they would continue with a GoActive activity. Suggested improvements included more mentorship; improved training; streamlined points recording. Pilot results indicated potential effectiveness ((adjusted mean difference (95% CI) p value; MVPA mins; 5.1 (1.1 to 9.2) p=0.014)) and suggest recruitment of 16 schools (2400 adolescents) for a full trial. Compared with control, intervention students reported greater peer support 0.5 (0.1 to 0.9) p=0.03, well-being 1.8 (0.1 to 3.4) p=0.04 but no difference in shyness/sociability. Participation in activity types approached significance (intervention group 2.3 (-0.2 to 4.7) p=0.07 more activity types). Results suggest feasibility and indicate potential effectiveness of GoActive to increase MVPA and support a fully powered evaluation of effectiveness and cost-effectiveness. Process evaluation data were used to refine GoActive prior to a full trial. ISRCTN31583496; pre-results. Published by the BMJ Publishing Group Limited.

Cardiovascular prevention is more effective if started early in life, but available interventions to promote healthy lifestyle habits among youth have been ineffective. Impulsivity in particular has proven to be an important barrier to the adoption of healthy behaviors in youth. Observational evidence suggests that mindfulness interventions may reduce impulsivity and improve diet and physical activity. We hypothesize that mindfulness training in adjunct to traditional health education will improve dietary habits and physical activity among teenagers by reducing impulsive behavior and improving planning skills. The Commit to Get Fit study is a pilot cluster randomized controlled trial examining the feasibility, acceptability and preliminary efficacy of school-based mindfulness training in adjunct to traditional health education for promotion of a healthy diet and physical activity among adolescents. Two schools in central Massachusetts (30 students per school) will be randomized to receive mindfulness training plus standard health education (HE-M) or an attention-control intervention plus standard health education (HE-AC). Assessments will be conducted at baseline, intervention completion (2 months), and 8 months. Primary outcomes are feasibility and acceptability. Secondary outcomes include physical activity, diet, impulsivity, mood, body mass index, and quality of life. This study will provide important information about feasibility and preliminary estimates of efficacy of a school-delivered mindfulness and health education intervention to promote healthy dietary and physical activity behaviors among adolescents. Our findings will provide important insights about the possible mechanisms by which mindfulness training may contribute to behavioral change and inform future research in this important area.

Nimick, David A.; Von Guerard, Paul

1998-01-01

From the Preface: There are thousands of abandoned or inactive mines on or adjacent to public lands administered by the U.S. Forest Service, Bureau of Land Management, and National Park Service. Mine wastes from many of these abandoned mines adversely affect resources on public lands. In 1995, an interdepartmental work group within the Federal government developed a strategy to address remediation of the many abandoned mines on public lands. This strategy is based on using a watershed approach to address the abandoned mine lands (AML) problem. The USGS, working closely with the Federal land-management agencies (FLMAs), is key for the success of this watershed approach. In support of this watershed approach, the USGS developed an AML Initiative with pilot studies in the Boulder River in Montana and the Animas River in Colorado. The goal of these studies is to design and implement a reliable strategy that will supply the scientific information to the FLMAs so that land managers can develop efficient and cost-effective remediation of AML. The symposium 'Science for Watershed Decisions on Abandoned Mine Lands: Review of Preliminary Results' held in Denver, Colorado, on February 4-5, 1998, provided the FLMAs a first look at the techniques, data, and interpretations being generated by the USGS pilot studies. This multidisciplined effort already is proving very valuable to land managers in making science-based AML cleanup decisions and will continue to be of increasing value as additional and more complete information is obtained. Ongoing interaction between scientists and land managers is essential to insure the efficient continuation and success of AML cleanup efforts.

The present study describes the preliminary results of the use of 99mTc-anti-TNF-α scintigraphy as a new diagnostic approach to evaluate patients presenting with Graves' ophthalmopathy (GO). Patients (n=25) presenting at different inflammatory stages of GO and 10 healthy volunteers underwent 99mTc-anti-TNF-α scintigraphy. Images were obtained 15 min after the intravenous injection of 370 MBq (10 mCi) 99mTc-anti-TNF-α. Planar images were obtained in a 256×256 matrix (each lasting 5 min) and single photon emission computed tomography (SPECT) scan lasting 13 min. Regions of interest (ROI) were drawn on the orbit and cerebral hemispheres. The uptake of 99m Tc-anti-TNF-α in these regions was compared and positive scintigraphy established when the ROI was >2.5. In addition, uptake for each positive exam was scored as either slight (2.6-5.1), moderate (5.2-7.6), or high (>7.6). In this pilot study, 69 orbits were evaluated (1 patient had only 1 eye), and 27 had a positive CAS (≥3/7). Scintigraphies were positive in 38 orbits. Comparing the results of the exams with CAS, a high sensitivity and negative predictive values were determined for scintigraphy (96.3% and 96.7%, respectively). However, the specificity and the positive predictive values were 71.4% and 68.4%, respectively, with an accuracy of 81.2%. The exclusion of examinations that were slightly positive from the analysis resulted in an improvement in test accuracy (95.5%). The preliminary results suggest that 99mTc-anti-TNF-α scintigraphy is a promising procedure for the evaluation of active orbital inflammation in GO. © Georg Thieme Verlag KG Stuttgart · New York.

2009-12-01

The DOE's Big Sky Regional Carbon Sequestration Partnership has completed drilling the first continental flood basalt sequestration pilot borehole to a total depth (TD) of 4,110 feet on the Boise White Paper Mill property at Wallula, Washington. Site suitability was assessed prior to drilling by the 2007-2008 acquisition, processing and analysis of a four-mile, five-line three component seismic swath, which was processed as a single data-dense line. Analysis of the seismic survey data indicated a composite basalt formation thickness of {approx}8,000 feet and absence of major geologic structures (i.e., faults) along the line imaged by the seismic swath. Drilling ofmore » Wallula pilot borehole was initiated on January 13, 2009 and reached TD on April 6, 2009. Based on characterization results obtained during drilling, three basalt breccia zones were identified between the depth interval of 2,716 and 2,910 feet, as being suitable injection reservoir for a subsequent CO2 injection pilot study. The targeted injection reservoir lies stratigraphically below the massive Umtanum Member of the Grande Ronde Basalt, whose flow-interior section possesses regionally recognized low-permeability characteristics. The identified composite injection zone reservoir provides a unique and attractive opportunity to scientifically study the reservoir behavior of three inter-connected reservoir intervals below primary and secondary caprock confining zones. Drill cuttings, wireline geophysical logs, and 31one-inch diameter rotary sidewall cores provided geologic data for characterization of rock properties. XRF analyses of selected rock samples provided geochemical characterizations of the rocks and stratigraphic control for the basalt flows encountered by the Wallula pilot borehole. Based on the geochemical results, the pilot borehole was terminated in the Wapshilla Ridge 1 flow of the Grande Ronde Basalt Formation. Detailed hydrologic test characterizations of 12 basalt interflow reservoir zones and 3 flow-interior/caprock intervals were performed during drilling and immediately following reaching the final borehole drilling depth (i.e., 4,110 ft). In addition, six of the 12 basalt interflow zones were selected for detailed hydrochemical characterization. Results from the detailed hydrologic test characterization program provided the primary information on basalt interflow zone transmissivity/injectivity, and caprock permeability characteristics.« less

2013-06-01

The purpose of this study was to develop a tool to evaluate patient safety culture in nursing homes and to test its validity and reliability. A preliminary tool was developed through interviews with focus group, content validity tests, and a pilot study. A nationwide survey was conducted from February to April, 2011, using self-report questionnaires. Participants were 982 employees in nursing homes. Data were analyzed using Cronbach's alpha, item analysis, factor analysis, and multitrait/multi-Item analysis. From the results of the analysis, 27 final items were selected from 49 items on the preliminary tool. Items with low correlation with total scale were excluded. The 4 factors sorted by factor analysis contributed 63.4% of the variance in the total scale. The factors were labeled as leadership, organizational system, working attitude, management practice. Cronbach's alpha for internal consistency was .95 and the range for the 4 factors was from .86 to .93. The results of this study indicate that the Korean Patient Safety Culture Scale has reliability and validity and is suitable for evaluation of patient safety culture in Korean nursing homes.

Oral use of Streptococcus salivarius K12 in children with secretory otitis media: preliminary results of a pilot, uncontrolled study

PubMed Central

Di Pierro, Francesco; Di Pasquale, Daniele; Di Cicco, Maurizio

2015-01-01

Secretory otitis media (SOM) remains a common disease among children. Although its cause is not yet perfectly established, the pathology, often a sequel of acute otitis media (AOM), is mainly characterized by persistent fluid in the middle ear cavity. Twenty-two children with a diagnosis of SOM were treated daily for 90 days with an oral formulation containing the oral probiotic Streptococcus salivarius K12 (Bactoblis®). After treatment, the children were evaluated for AOM episodes and subjected to tone audiometry, tympanometry, endonasal endoscopy, otoscopy, and tonsillar examination. Subject compliance and probiotic tolerability and side effects have also been evaluated. Our results indicate a good safety profile, a substantial reduction of AOM episodes, and a positive outcome from the treatment for all of the clinical outcomes tested. We conclude that strain K12 may have a role in reducing the occurrence and/or severity of SOM in children. From our perspective, this study constitutes a starting point toward the organization of a more extensive placebo-controlled study aimed at critically appraising our preliminary observations.

Background eHealth facilitation of chronic disease management has potential to increase engagement and effectiveness and extend access to care in rural areas. Objective The objective of this study was to demonstrate the feasibility and acceptability of an eHealth system for the management of chronic conditions in a rural setting. Methods We developed an online management program which incorporated content from the Flinders Chronic Condition Management Program (Flinders Program) and used an existing software platform (goACT), which is accessible by patients and health care workers using either Web-enabled mobile phone or Internet, enabling communication between patients and clinicians. We analyzed the impact of this eHealth system using qualitative and simple quantitative methods. Results The eHealth system was piloted with 8 recently hospitalized patients from rural areas, average age 63 (SD 9) years, each with an average of 5 chronic conditions and high level of psychological distress with an average K10 score of 32.20 (SD 5.81). Study participants interacted with the eHealth system. The average number of logins to the eHealth system by the study participants was 26.4 (SD 23.5) over 29 weeks. The login activity was higher early in the week. Conclusions The pilot demonstrated the feasibility of implementing and delivering a chronic disease management program using a Web-based patient-clinician application. A qualitative analysis revealed burden of illness and low levels of information technology literacy as barriers to patient engagement. PMID:24927511

The Adult Social Care Outcomes Toolkit was developed to measure outcomes of social care in England. In this study, we translated the four level self-completion version (SCT-4) of the ASCOT for use in the Netherlands and performed a cross-cultural validation. The ASCOT SCT-4 was translated into Dutch following international guidelines, including two forward and back translations. The resulting version was pilot tested among frail older adults using think-aloud interviews. Furthermore, using a subsample of the Dutch ACT-study, we investigated test-retest reliability and construct validity and compared response distributions with data from a comparable English study. The pilot tests showed that translated items were in general understood as intended, that most items were reliable, and that the response distributions of the Dutch translation and associations with other measures were comparable to the original English version. Based on the results of the pilot tests, some small modifications and a revision of the Dignity items were proposed for the final translation, which were approved by the ASCOT development team. The complete original English version and the final Dutch translation can be obtained after registration on the ASCOT website ( http://www.pssru.ac.uk/ascot ). This study provides preliminary evidence that the Dutch translation of the ASCOT is valid, reliable and comparable to the original English version. We recommend further research to confirm the validity of the modified Dutch ASCOT translation.

Polarization sensitive (PS) OCT measures the polarization states of the light backscattered by tissue and provides measures of tissue birefringence and depolarization in addition to the structural OCT signal. Ex vivo studies have demonstrated that birefringence is increased in tissue rich in collagen and with elevated smooth muscle cell content. Preliminary data further suggests that depolarization can identify regions of macrophage infiltration, lipid, and irregularly arranged collagen fibers. These are important aspects of the mechanical integrity and vulnerability of atherosclerotic plaques. To evaluate the potential of PS-OCT in the clinical setting, we combined our custom PS-OCT system with commercially available OCT catheters (Fastview, Terumo Corporation) and performed a pilot study in 30 patients, scheduled to undergo percutaneous coronary intervention (PCI) on the grounds of stable or unstable angina. A total of 82 pullbacks in 39 vessels were performed, either in the native coronary arteries or post procedure. Comparing consecutive pullbacks of the same coronary artery, we found excellent agreement between the polarization features in the repeat pullbacks, validating the repeatability and robustness of PS-OCT in the clinical in vivo setting. In addition we observed that the birefringence and depolarization features vary significantly across lesions with identical structural OCT appearance, suggesting morphological subtypes. This first human pilot study proved the feasibility and robustness of intravascular PS-OCT. PS-OCT achieves improved tissue characterization and may help in identifying high-risk plaques, with the potential to ultimately improve risk stratification and help guiding PCI.

Disruptive Effects of Colorful vs. Non-colorful Play Area on Structured Play-A Pilot Study with Preschoolers.

To contribute to young children's development, sensory enrichment is often provided via colorful play areas. However, little is known about the effects of colorful environments on children while they engage in age-appropriate tasks and games. Studies in adults suggest that aspects of color can distract attention and impair performance, and children are known to have less developed attentional and executive abilities than adults. Preliminary studies conducted in children aged 5-8 suggest that the colorfulness of both distal (e.g., wall decorations) and proximal (e.g., the surface of the desktop) environments can have a disruptive effect on children's performance. The present research seeks to extend the previous studies to an even younger age group and focus on proximal colorfulness. With a sample of 15 pre-schoolers (3-4 years old) we examined whether a colorful play surface compared to a non-colorful (white) play surface would affect engagement in developmentally appropriate structured play. Our pilot findings suggest that a colorful play surface interfered with preschoolers' structured play, inducing more behaviors indicating disruption in task execution compared with a non-colorful play surface. The implications of the current study for practice and further research are discussed.

Improving proprioceptive deficits after stroke through robot-assisted training of the upper limb: a pilot case report study.

2016-01-01

The purpose of this study was to determine whether a conventional robot-assisted therapy of the upper limb was able to improve proprioception and motor recovery of an individual after stroke who exhibited proprioceptive deficits. After robotic sensorimotor training, significant changes were observed in kinematic performance variables. Two quantitative parameters evaluating position sense improved after training. Range of motion during shoulder and wrist flexion improved, but only wrist flexion remained improved at 3-month follow-up. These preliminary results suggest that intensive robot-aided rehabilitation may play an important role in the recovery of sensory function. However, further studies are required to confirm these data.

Preliminary design study of a lateral-directional control system using thrust vectoring

NASA Technical Reports Server (NTRS)

Lallman, F. J.

1985-01-01

A preliminary design of a lateral-directional control system for a fighter airplane capable of controlled operation at extreme angles of attack is developed. The subject airplane is representative of a modern twin-engine high-performance jet fighter, is equipped with ailerons, rudder, and independent horizontal-tail surfaces. Idealized bidirectional thrust-vectoring engine nozzles are appended to the mathematic model of the airplane to provide additional control moments. Optimal schedules for lateral and directional pseudo control variables are calculated. Use of pseudo controls results in coordinated operation of the aerodynamic and thrust-vectoring controls with minimum coupling between the lateral and directional airplane dynamics. Linear quadratic regulator designs are used to specify a preliminary flight control system to improve the stability and response characteristics of the airplane. Simulated responses to step pilot control inputs are stable and well behaved. For lateral stick deflections, peak stability axis roll rates are between 1.25 and 1.60 rad/sec over an angle-of-attack range of 10 deg to 70 deg. For rudder pedal deflections, the roll rates accompanying the sideslip responses can be arrested by small lateral stick motions.

Stereoplotting Hominid Brain Endocasts : Some Preliminary Results

NASA Astrophysics Data System (ADS)

Holloway, Ralph L.

1980-07-01

To objectively and quantitatively demonstrate regional differences in brain endocast morphology, traditional anthropometric caliper measurements must be replaced by a system providing not only localness, but homology and reasonable freedom from allometric distortion. Stereoplotting the radial distances from endocast surface (the closest point to the once underlying brain cortex) to a homologous center every ten degrees provides some 300+ data points for each dorsal endocast surface, thus giving the requisite localness. These measurements provide a large matrix of data suitable for a number of multivariate statistical techniques, and the translation of such data and analyses to readily visualized maps, which can then be compared in relation to both taxonomic and functional knowledge about the cerebral surface. This paper descri-bes some preliminary results from using such methods on a sample of 64 undistorted endocasts composed of both pongids and fossil hominids. While sample sizes within taxonomic groups need to be augmented, the preliminary and tentative pilot studies conducted so far suggest that the method has excellent potential, and that two major areas of the brain endocast surface show the greatest shape changes : 1) the posterior association areas (inferior parietal lobule); 2) the anterior prefrontal areas.

We present a hand-held implementation and preliminary evaluation of a combined optical coherence tomography (OCT) and reflectance confocal microscopy (RCM) probe for detecting and delineating the margins of basal cell carcinomas (BCCs) in human skin in vivo. A standard OCT approach (spectrometer-based) with a central wavelength of 1310 nm and 0.11 numerical aperture (NA) was combined with a standard RCM approach (830-nm wavelength and 0.9 NA) into a common path hand-held probe. Cross-sectional OCT images and enface RCM images are simultaneously displayed, allowing for three-dimensional microscopic assessment of tumor morphology in real time. Depending on the subtype and depth of the BCC tumor and surrounding skin conditions, OCT and RCM imaging are able to complement each other, the strengths of each helping overcome the limitations of the other. Four representative cases are summarized, out of the 15 investigated in a preliminary pilot study, demonstrating how OCT and RCM imaging may be synergistically combined to more accurately detect BCCs and more completely delineate margins. Our preliminary results highlight the potential benefits of combining the two technologies within a single probe to potentially guide diagnosis as well as treatment of BCCs.

Low- and middle-income countries often have limited resources, underdeveloped health systems and scarce knowledge of autism spectrum disorder. The objectives of this preliminary study were to develop and adapt intervention materials and to train a native clinician to implement a community-based parent-mediated behavioural intervention in rural Gaibandha, Bangladesh. Intervention materials to support parents' use of behavioural strategies were developed and refined by US behavioural intervention experts and Bangladesh field experts. Study investigators trained a native child psychologist in developmental milestones and behavioural intervention techniques. The native clinician delivered a 1-day group education session attended by 10 families of children aged 7-9 years with autism spectrum disorder, followed by two one-on-one training sessions with each family to train and practice individualized strategies for targeted challenging behaviours. Preliminary qualitative results indicate the importance of materials that are culturally appropriate and at an adequate literacy level. All families expressed strong desires to have learned the behavioural strategies when their child was younger and vocalized their need for further support and tools to help their children. This study is a preliminary step to creating sustainable and low-cost autism spectrum disorder interventions in rural Bangladesh, and possibly for families in regions with similar cultural and socioeconomic status backgrounds.

This paper is a report of preliminary evaluations of an interprofessional education through simulation project by focusing on learner and teacher reactions to the pilot modules. Approaches to interprofessional education vary widely. Studies indicate, however, that active, experiential learning facilitate it. Patient simulators require learners to incorporate knowing, being and doing in action. A theoretically based competency framework was developed to guide interprofessional education using simulation. The framework includes a typology of shared, complementary and profession-specific competencies. Each competency type is associated with an intraprofessional, multiprofessional, or interprofessional teaching modality and with the professional composition of learner groups. The project is guided by an action research approach in which ongoing evaluation generates knowledge to modify and further develop it. Preliminary evaluations of the first pilot module, cardiac resuscitation rounds, among 101 nursing students, 42 medical students and 70 junior medical residents were conducted in 2005-2007 using a questionnaire with rating scales and open-ended questions. Another 20 medical students, 7 junior residents and 45 nursing students completed a questionnaire based on the Interdisciplinary Education Perception scale. Simulation-based learning provided students with interprofessional activities they saw as relevant for their future as practitioners. They embraced both the interprofessional and simulation components enthusiastically. Attitudinal scores and responses were consistently positive among both medical and nursing students. Interprofessional education through simulation offers a promising approach to preparing future healthcare professionals for the collaborative models of healthcare delivery being developed internationally.

In June 1992, the School of Aerospace Engineering at Georgia Tech was awarded a three year NASA University Space Research Association (USRA) Advanced Design Program (ADP) grant to address issues associated with the Integrated Design and Manufacturing of High Speed Civil Transport (HSCT) configurations in its graduate Aerospace Systems Design courses. This report provides an overview of the on-going Georgia Tech initiative to address these design/manufacturing issues during the preliminary design phases of an HSCT concept. The new design methodology presented here has been incorporated in the graduate aerospace design curriculum and is based on the concept of Integrated Product and Process Development (IPPD). The selection of the HSCT as a pilot project was motivated by its potential global transportation payoffs; its technological, environmental, and economic challenges; and its impact on U.S. global competitiveness. This pilot project was the focus of each of the five design courses that form the graduate level aerospace systems design curriculum. This year's main objective was the development of a systematic approach to preliminary design and optimization and its implementation to an HSCT wing/propulsion configuration. The new methodology, based on the Taguchi Parameter Design Optimization Method (PDOM), was established and was used to carry out a parametric study where various feasible alternative configurations were evaluated. The comparison criterion selected for this evaluation was the economic impact of this aircraft, measured in terms of average yield per revenue passenger mile ($/RPM).

Human immunodeficiency virus (HIV) prevention intervention programs and related research for men who have sex with men (MSM) in the southern African region remain limited, despite the emergence of a severe epidemic among this group. With a lack of understanding of their social and sexual lives and HIV risks, and with MSM being a hidden and stigmatized group in the region, optimized HIV prevention packages for southern African MSM are an urgent public health and research priority. The objective of the Sibanye Health Project is to develop and evaluate a combination package of biomedical, behavioral, and community-level HIV prevention interventions and services for MSM in South Africa. The project consists of three phases: (1) a comprehensive literature review and summary of current HIV prevention interventions (Phase I), (2) agent-based mathematical modeling of HIV transmission in southern African MSM (Phase II), and (3) formative and stigma-related qualitative research, community engagement, training on providing health care to MSM, and the pilot study (Phase III). The pilot study is a prospective one-year study of 200 men in Cape Town and Port Elizabeth, South Africa. The study will assess a package of HIV prevention services, including condom and condom-compatible lubricant choices, risk-reduction counseling, couples HIV testing and counseling, pre-exposure prophylaxis (PrEP) for eligible men, and non-occupational post-exposure prophylaxis for men with a high risk exposure. The pilot study will begin in October 2014. Preliminary results from all components but the pilot study are available. We developed a literature review database with meta-data extracted from 3800 documents from 67 countries. Modeling results indicate that regular HIV testing and promotion of condom use can significantly impact new HIV infections among South African MSM, even in the context of high coverage of early treatment of HIV-positive men and high coverage of PrEP for at-risk HIV-negative men. Formative qualitative research consisted of 79 in-depth interviews, and six focus group discussions in Cape Town and Port Elizabeth. Analysis of these data has informed pilot study protocol development and has been documented in peer-reviewed manuscripts. Qualitative work regarding stigma faced by South African MSM resulted in finalized scales for use in the pilot study questionnaire. A total of 37 health care providers completed training designed to facilitate clinically and culturally competent care for MSM in the Eastern Cape. The design of a future, larger study of the HIV prevention package will be conducted at the end of the pilot study, powered to detect efficacy of the prevention package. Data from the updated mathematical model, results of the pilot study, acceptability data, and advancements in HIV prevention sciences will be considered in developing the final proposed package and study design.

Introduction The Public Health England (PHE; United Kingdom) Real-Time Syndromic Surveillance Team (ReSST) currently operates four national syndromic surveillance systems, including an emergency department system. A system based on ambulance data might provide an additional measure of the "severe" end of the clinical disease spectrum. This report describes the findings and lessons learned from the development and preliminary assessment of a pilot syndromic surveillance system using ambulance data from the West Midlands (WM) region in England. Hypothesis/Problem Is an Ambulance Data Syndromic Surveillance System (ADSSS) feasible and of utility in enhancing the existing suite of PHE syndromic surveillance systems? An ADSSS was designed, implemented, and a pilot conducted from September 1, 2015 through March 1, 2016. Surveillance cases were defined as calls to the West Midlands Ambulance Service (WMAS) regarding patients who were assigned any of 11 specified chief presenting complaints (CPCs) during the pilot period. The WMAS collected anonymized data on cases and transferred the dataset daily to ReSST, which contained anonymized information on patients' demographics, partial postcode of patients' location, and CPC. The 11 CPCs covered a broad range of syndromes. The dataset was analyzed descriptively each week to determine trends and key epidemiological characteristics of patients, and an automated statistical algorithm was employed daily to detect higher than expected number of calls. A preliminary assessment was undertaken to assess the feasibility, utility (including quality of key indicators), and timeliness of the system for syndromic surveillance purposes. Lessons learned and challenges were identified and recorded during the design and implementation of the system. The pilot ADSSS collected 207,331 records of individual ambulance calls (daily mean=1,133; range=923-1,350). The ADSSS was found to be timely in detecting seasonal changes in patterns of respiratory infections and increases in case numbers during seasonal events. Further validation is necessary; however, the findings from the assessment of the pilot ADSSS suggest that selected, but not all, ambulance indicators appear to have some utility for syndromic surveillance purposes in England. There are certain challenges that need to be addressed when designing and implementing similar systems.

Comparison of corrosion scales in full and partially replaced ...

EPA Pesticide Factsheets

Preliminary results from scales formed 38 weeks following the LSL replacement simulations revealed differences in scale formations amongst varying water qualities and pipe sequence. Rigs fed with dechlorinated tap water show distinct pH gradients between the galvanic and the background zones. Hydrocerussite and litharge are found both in field and pilot rigs. However, plumbonacrite, massicot, scrutinyite and plattnerite are only present in pipes harvested directly from the field. Laurionite, leadhillite, cerussite and calcite are found in rigs from the pilot. Cerussite is mostly present in the galvanic zones, close to the connection to the Cu pipe. Different types of scales are present in the rigs from the pilot and from the field, suggesting that differences in the formation in the scales and therefore differences in lead release from the pipes. The particulate Pb fraction in water samples is more important in samples from the pilot than from the field, median concentrations are 85X higher in partial LSL and 10X higher in full LSL in the pilot. Lead phosphates are present in the scales from the rigs treated with orthophosphate. Complete results will be obtained by the end of July 2016. The main objective is to compare scales from full and partial LSLs harvested from the field and from a pilot setup fed with water from the same distribution system and subjected to water quality changes.

Evaluation of Solid Sorbents as a Retrofit Technology for CO 2 Capture

DOE Office of Scientific and Technical Information (OSTI.GOV)

Sjostrom, Sharon

2016-06-02

ADA completed a DOE-sponsored program titled Evaluation of Solid Sorbents as a Retrofit Technology for CO 2 Capture under program DE-FE0004343. During this program, sorbents were analyzed for use in a post-combustion CO 2 capture process. A supported amine sorbent was selected based upon superior performance to adsorb a greater amount of CO 2 than the activated carbon sorbents tested. When the most ideal sorbent at the time was selected, it was characterized and used to create a preliminary techno-economic analysis (TEA). A preliminary 550 MW coal-fired power plant using Illinois #6 bituminous coal was designed with a solid sorbentmore » CO 2 capture system using the selected supported amine sorbent to both facilitate the TEA and to create the necessary framework to scale down the design to a 1 MWe equivalent slipstream pilot facility. The preliminary techno-economic analysis showed promising results and potential for improved performance for CO 2 capture compared to conventional MEA systems. As a result, a 1 MWe equivalent solid sorbent system was designed, constructed, and then installed at a coal-fired power plant in Alabama. The pilot was designed to capture 90% of the CO 2 from the incoming flue gas at 1 MWe net electrical generating equivalent. Testing was not possible at the design conditions due to changes in sorbent handling characteristics at post-regenerator temperatures that were not properly incorporated into the pilot design. Thus, severe pluggage occurred at nominally 60% of the design sorbent circulation rate with heated sorbent, although no handling issues were noted when the system was operated prior to bringing the regenerator to operating temperature. Testing within the constraints of the pilot plant resulted in 90% capture of the incoming CO 2 at a flow rate equivalent of 0.2 to 0.25 MWe net electrical generating equivalent. The reduction in equivalent flow rate at 90% capture was primarily the result of sorbent circulation limitations at operating temperatures combined with pre-loading of the sorbent with CO 2 prior to entering the adsorber. Specifically, CO 2-rich gas was utilized to convey sorbent from the regenerator to the adsorber. This gas was nominally 45°C below the regenerator temperature during testing. ADA’s post-combustion capture system with modifications to overcome pilot constraints, in conjunction with incorporating a sorbent with CO 2 working capacity of 15 g CO 2/100 g sorbent and a contact time of 10 to 15 minutes or less with flue gas could provide significant cost and performance benefits when compared to an MEA system.« less

Objective The purpose of this pilot study was to (1) obtain preliminary data on changes in burden and quality of life in head and neck cancer caregivers during and shortly following patient radiotherapy, (2) assess the relationship between perceived social support and burden as well as perceived social support and quality of life in caregivers during radiotherapy, and (3) identify preferences for sources of support among caregivers during radiotherapy. Methods Caregivers completed burden and quality of life instruments at the start of patient radiotherapy (T1), 5 weeks into radiotherapy (T2), and 1 month post-radiotherapy (T3) and instruments for perceived social support and support preferences at T2 only. Results Caregivers showed a trend toward increased burden and worsened quality of life for the majority of subscales at T2 or T3 than at T1. Caregivers reported significantly lower esteem and significantly greater disruption at T2 than at T1 and significantly worse health at T3 than at T2. Higher perceived social support was typically associated with lower burden and higher quality of life at T2. Spouses/partners were the most commonly preferred source of support. Discussion These pilot findings suggest that caregivers experience psychosocial impairments during and shortly after patient radiotherapy, but more research using larger samples is warranted.

Young children of mothers with adult attention-deficit/hyperactivity disorder (ADHD) are at risk for ADHD by virtue of genetics and environmental factors. Moreover, parent ADHD is associated with maladaptive parenting and poor child behavioral treatment response. Thus, a combined approach consisting of behavioral parent training (BPT) and maternal stimulant medication (MSM) may be needed to effectively treat ADHD within families. However, providing combined BPT+MSM initially to all families may be unnecessarily burdensome because not all families likely need combined treatment. The purpose of this study is to examine how to combine, sequence, and personalize treatment for these multiplex families in order to yield benefits to both the parent and child, thereby impacting the course of child ADHD and disruptive behavior symptoms. This article presents our rationale for, design of, and preliminary experiences (based on 26 participants) with an ongoing pilot Sequential Multiple Assessment Randomized Trial (SMART) designed to answer questions regarding the feasibility and acceptability of study protocols and interventions. This article also describes how the subsequent full-scale SMART might change based on what is learned in the SMART pilot and illustrates how the full-scale SMART could be used to inform clinical decision making about how to combine, sequence, and personalize treatment for complex children and families in which a parent has ADHD.

A pilot system for environmental monitoring is in its early phases of development in Northern California. It is based upon the existing nation wide Federal-State Market Cattle Testing (14CT) program for brucellosis in cattle. This latter program depends upon the collection of blood program at the time of identified cattle. As the cattle Population of California is broadly distributed throughout the state, we intend to utilize these blood samples to biologically monitor the distribution and intensity of selected environmental pollutants. In a 2-year preliminary trial, the feasibility of retrieving, utilizing for a purpose similar to this, and tracing back to their geographic areas of origin of MCT samples have been demonstrated.

Based on results from bench-scale flow-film-reactors (FFR) and aerated cascade photoreactors, a solar catalytic pilot plant has been built at the site of a textile factory. This plant has an illuminated surface area of 50 m2 and is designed for the treatment of 1 m3 h(-1) of wastewater. The preliminary results are presented and compared with a bench-scale FFR using textile wastewater and dichloroacetic acid. Equivalent degradation kinetics were obtained and it was demonstrated that the solar catalytic technology is able to remove recalcitrant compounds and color. However, on-site optimization is still necessary for wastewater reuse and for an economic application.

The goal of this pilot program was to test the usefulness of adapted Problem-Solving Therapy (PST) and anxiety management, called PROTECT, integrated into elder abuse services to reduce depression and improve self-efficacy. Depressed women victims were randomized to receive elder abuse resolution services combined with either PROTECT or a mental health referral. At follow-up, the PROTECT group showed greater reduction in depressive symptoms and endorsed greater improved self-efficacy in problem-solving when compared to those in the Referral condition. These preliminary findings support the potential usefulness of PROTECT to alleviate depressive symptoms and enhance personal resources among abused older women.

To explore the feasibility of using a simple multi-criteria decision analysis method with policy makers/key stakeholders to prioritize cardiovascular disease (CVD) policies in four Mediterranean countries: Palestine, Syria, Tunisia and Turkey. A simple multi-criteria decision analysis (MCDA) method was piloted. A mixed methods study was used to identify a preliminary list of policy options in each country. These policies were rated by different policymakers/stakeholders against pre-identified criteria to generate a priority score for each policy and then rank the policies. Twenty-five different policies were rated in the four countries to create a country-specific list of CVD prevention and control policies. The response rate was 100% in each country. The top policies were mostly population level interventions and health systems' level policies. Successful collaboration between policy makers/stakeholders and researchers was established in this small pilot study. MCDA appeared to be feasible and effective. Future applications should aim to engage a larger, representative sample of policy makers, especially from outside the health sector. Weighting the selected criteria might also be assessed.

The effects of energy beverages in counteracting the symptoms of mild hypoxia at legal general aviation altitudes

NASA Astrophysics Data System (ADS)

Bull, Daniel Mark

The purpose of this thesis was to conduct preliminary research, in the form of a pilot study, concerning the natural effects of hypoxia compared to the effects of hypoxia experienced after the consumption of an energy beverage. The study evaluated the effects of hypoxia on FAA certificated pilots at a simulated legal general aviation altitude, utilizing the normobaric High Altitude Lab (HAL) located at Embry Riddle Aeronautical University, Daytona Beach, Florida. The researcher tested 11 subjects, who completed three simulated flight tasks within the HAL using the Frasca International Mentor Advanced Aviation Training Device (AATD). The flight tasks were completed after consuming Red BullRTM, MonsterRTM , or a placebo beverage. The researcher derived three test variables from core outputs of the AATD: lateral deviations from the glide slope, vertical deviations from the localizer, and airspeed deviations from the target speed of 100 knots. A repeated-measures ANOVA was carried out to determine effects of the beverages on the test variables. While results were non-significant, the researcher concluded that further research should be conducted with a larger sample.

This pilot study evaluated a body image intervention for men, Body Project M. Seventy-four British undergraduate men took part in two 90-min intervention sessions, and completed standardised assessments of body image, bulimic pathology, and related outcomes at baseline, post-intervention, and 3-month follow-up. Fifty-three other men completed the questionnaires as an assessment-only control group. Per-protocol analysis showed that Body Project M improved men's dissatisfaction with body fat and muscularity, body appreciation, muscularity enhancing behaviours, appearance comparisons, and internalization (ds=0.46-0.80) at post-intervention. All except dissatisfaction with muscularity and internalization were sustained at 3-month follow-up. No effects were found for bulimic pathology. Post-intervention effects for dissatisfaction with muscularity and internalization only were retained under intention-to-treat analysis. Participants were favourable towards the intervention. This study provides preliminary evidence for the acceptability and post-intervention efficacy of Body Project M. Further development of the intervention is required to improve and sustain effects.

This paper presents an approach for assisting low-literacy readers in accessing Web online information. The "Educational FACILITA" tool is a Web content adaptation tool that provides innovative features and follows more intuitive interaction models regarding accessibility concerns. Especially, we propose an interaction model and a Web application that explore the natural language processing tasks of lexical elaboration and named entity labeling for improving Web accessibility. We report on the results obtained from a pilot study on usability analysis carried out with low-literacy users. The preliminary results show that "Educational FACILITA" improves the comprehension of text elements, although the assistance mechanisms might also confuse users when word sense ambiguity is introduced, by gathering, for a complex word, a list of synonyms with multiple meanings. This fact evokes a future solution in which the correct sense for a complex word in a sentence is identified, solving this pervasive characteristic of natural languages. The pilot study also identified that experienced computer users find the tool to be more useful than novice computer users do.

To evaluate the efficacy, tolerability, and impact on quality of life (QoL) of bromelain tablets (500 FIP) in patients with chronic rhinosinusitis (CRS). In this prospective, open-label observational pilot study, 12 patients suffering from CRS with (CRS+NP) or without (CRS-NP) nasal polyps who had undergone prior sinus surgery were treated with bromelain tablets (500 FIP) for three months. Efficacy was evaluated using symptom scores (Total Symptom Scores: TSS); a Total Rhinoscopy Score (TRS) was also determined. QoL was assessed by using the German, adapted version of the Sinonasal Outcome Test 20 (SNOT-20 GAV). Treatment with bromelain tablets (500 FIP) improved TSS, TRS and SNOT-20 GAV on average. This treatment was found to be more effective, however, for CRS-NP than for CRS+NP. The average intake was six tablets, equivalent to a daily dosage of 3000 FIP. No adverse events were observed. Preliminary results indicate good tolerability, symptom control, and improvement in QoL for the treatment of CRS using bromelain tablets (500 FIP).

Preclinical and clinical studies show that the GABAB receptor agonist baclofen may represent a pharmacotherapy for alcohol dependence (AD). However, the mechanisms by which baclofen affects drinking are not well characterized; thus this pilot study investigated possible baclofen’s biobehavioral mechanisms. The design was a double-blind controlled randomized human laboratory pilot study. Fourteen non-treatment seeking alcohol-dependent heavy drinking subjects received either baclofen 10 mg t.i.d. or an active placebo (cyproheptadine 2 mg t.i.d., to control for sedation) for a 7-day period. At day 8, participants performed an alcohol cue-reactivity (CR) followed by an alcohol self-administration (ASA). Additionally, we explored possible moderators that might guide future larger studies, i.e. anxiety, family history and onset of alcoholism, and D4 dopamine receptor (DRD4) and 5-HTTLPR polymorphisms. The main results were a significant effect of baclofen for increasing stimulation (p=.001) and sedation (p<.01). Furthermore, when drinking during the ASA and the 2 days before was analyzed as a composite variable, there was a significant effect of baclofen to reduce alcohol consumption (p<.01). As for the exploratory analyses, baclofen’s effects to increase alcohol sedation and to reduce alcohol consumption were limited to those individuals with DRD4 ≥7 repeats (DRD4L). Yet, baclofen’s effects on alcohol consumption were also moderated by 5-HTTLPR LL genotype. In conclusion, baclofen’s ability to reduce alcohol drinking may be related to its effects on the biphasic effects of alcohol, but larger studies are needed to confirm these preliminary findings.

Parkinson's disease (PD) affects speech in the majority of patients. Subthalamic nucleus deep brain stimulation (STN-DBS) is particularly effective in reducing tremor and rigidity. However, its effect on speech is variable. The aim of this pilot study was to quantify the effects of bilateral STN-DBS and medication on articulation, using electropalatography (EPG). Two patients, PT1 and PT2, were studied under four conditions: on and off medication and ON and OFF stimulation. The EPG protocol consisted of a number of target words with alveolar and velar stops, repeated 10 times in random order. The motor part III of the Unified Parkinson Disease Rating Scale (UPDRS) indicated significantly improved motor scores in the ON stimulation condition in both patients. However, PT1's articulation patterns deteriorated with stimulation whereas PT2 showed improving articulatory accuracy in the same condition. The results revealed different effects of stimulation and medication on articulation particularly with regard to timing. The study quantified less articulatory undershoot for velar stops in comparison to alveolars. Furthermore, the findings provided preliminary evidence that stimulation with medication has a more detrimental effect on articulation than stimulation without medication.

A study was conducted employing the Visual Motion Simulator (VMS) at the NASA Langley Research Center, Hampton, Virginia. This study compared two motion cueing algorithms, the NASA adaptive algorithm and a new optimal control based algorithm. Also, the study included the effects of transport delays and the compensation thereof. The delay compensation algorithm employed is one developed by Richard McFarland at NASA Ames Research Center. This paper reports on the analyses of the results of analyzing the experimental data collected from preliminary simulation tests. This series of tests was conducted to evaluate the protocols and the methodology of data analysis in preparation for more comprehensive tests which will be conducted during the spring of 2003. Therefore only three pilots were used. Nevertheless some useful results were obtained. The experimental conditions involved three maneuvers; a straight-in approach with a rotating wind vector, an offset approach with turbulence and gust, and a takeoff with and without an engine failure shortly after liftoff. For each of the maneuvers the two motion conditions were combined with four delay conditions (0, 50, 100 & 200ms), with and without compensation.

Sexual and gender minority (SGM) individuals experience high rates of harassment and discrimination when seeking healthcare, which contributes to substantial healthcare disparities. Improving physician training about gender identity, sexual orientation, and the healthcare needs of SGM patients has been identified as a critical strategy for mitigating these disparities. In 2014, the Association of American Medical Colleges (AAMC) published medical education competencies to guide undergraduate medical education on SGM topics. Conduct pilot study to investigate medical student comfort and competence about SGM health competencies outlined by the AAMC and evaluate curricular coverage of SGM topics. Six-hundred and fifty-eight students at New England allopathic medical schools (response rate 21.2%) completed an anonymous, online survey evaluating self-reported comfort and competence regarding SGM health competencies, and coverage of SGM health in the medical curriculum. 92.7% of students felt somewhat or very comfortable treating sexual minorities; 68.4% felt comfortable treating gender minorities. Most respondents felt not competent or somewhat not competent with medical treatment of gender minority patients (76.7%) and patients with a difference of sex development (81%). At seven schools, more than 50% of students indicated that the curriculum neither adequately covers SGM-specific topics nor adequately prepares students to serve SGM patients. The prevalence of self-reported comfort is greater than that of self-reported competence serving SGM patients in a convenience sample of New England allopathic medical students. The majority of participants reported insufficient curricular preparation to achieve the competencies necessary to care for SGM patients. This multi-institution pilot study provides preliminary evidence that further curriculum development may be needed to enable medical students to achieve core competencies in SGM health, as defined by AAMC. Further mixed methods research is necessary to substantiate and expand upon the findings of this pilot study. This pilot study also demonstrates the importance of creating specific evaluation tools to assess medical student achievement of competencies established by the AAMC.

Alcohol-based hand sanitizer (HS) kills most organisms that cause acute illness, an important cause of lost duty time among aviation personnel. This preliminary study observed the impact on the acute illness rate when HS was made readily accessible to pilots. Wall-mounted HS dispensers were placed in two fighter squadron operations buildings during November 2005 and various media were used to alert all base personnel to the importance of hand hygiene and cough hygiene. Data were obtained for two groups of personnel on the same base: 1) pilots who worked in the two HS-equipped buildings (Squadron) (n = 56); and 2) pilots and air traffic controllers who worked at other locations (Non-Squadron) (n = 61). The incidence of acute illness and the cumulative number of duty days lost was determined in each group for the winters of 2004-05 (no HS) and 2005-06 (HS available). For the Squadron group, the acute illness rates were 2.4% in 2004-5 (210 duty days lost) (no HS) compared with 0.9% in 2005-6 (78 duty days lost) when HS was provided. No year-to-year difference was apparent for the Non-Squadron group, where the illness rates were 2.4% in 2004-5 (229 duty days lost) and 2.3% in 2005-6 (221 duty days lost). Making HS readily available at locations frequented by pilots together with educating them regarding hand hygiene may reduce the occurrence of acute illness and number of duty days lost.

Pilot-scale vermicomposting was explored using Eudrilus eugeniae for 90 days with 45 days preliminary decomposition using different agro-industrial wastes as substrates. Spent wash and pressmud were mixed together (referred to as PS) and then combined with cow dung (CD) at five different ratios of PS:CD, namely, 25:75 (T1), 50:50 (T2), 75:25 (T3), 85:15 (T4) and 100 (T5), with two replicates for each treatment. All vermibeds expressed a significant decrease in pH (11.4-14.8%), organic carbon (4.2-30.5%) and an increase in total nitrogen (6-29%), AP (5-29%), exchangeable potash (6-21%) and turnover rate (52-66%). Maximum mortality (18.10%) of worms was recorded in T5 treatment. A high manurial value and a matured product was achieved in T3 treatment. The data reveal that pressmud mixed with spent wash can be decomposed through vermicomposting and can help to enhance the quality of vermicompost.

Since its identification as a potential deep geologic repository in about 1973, the regulatory assessment process for the Waste Isolation Pilot Plant (WIPP) in New Mexico has developed over the past 25 years. National policy issues, negotiated agreements, and court settlements over the first half of the project had a strong influence on the amount and type of scientific data collected. Assessments and studies before the mid 1980s were undertaken primarily (1) to satisfy needs for environmental impact statements, (2) to develop general understanding of selected natural phenomena associated with nuclear waste disposal, or (3) to satisfy negotiated agreements withmore » the State of New Mexico. In the last third of the project, federal compliance policy and actual regulations were sketched out, but continued to evolve until 1996. During this eight-year period, four preliminary performance assessments, one compliance performance assessment, and one verification performance assessment were performed.« less

Two-thirds of those with HIV worldwide live in sub-Saharan Africa. Alcohol use is associated with the HIV epidemic through risky sex and suboptimal ARV adherence. In western Kenya, hazardous drinking was reported by HIV (53%) and general medicine (68%) outpatients. Cognitive behavioral treatment (CBT) has demonstrated strong efficacy to reduce alcohol use. This article reports on a systematic cultural adaptation and pilot feasibility study of group paraprofessional-delivered CBT to reduce alcohol use among HIV-infected outpatients in Eldoret, Kenya. Following adaptation and counselor training, five pilot groups were run (n = 27). Overall attendance was 77%. Percent days abstinent from alcohol (PDA) before session 1 was 52-100% (women) and 21-36% (men), and by session 6 was 96-100% (women) and 89-100% (men). PDA effect sizes (Cohen's d) between first and last CBT session were 2.32 (women) and 2.64 (men). Participants reported treatment satisfaction. Results indicate feasibility, acceptability and preliminary efficacy for CBT in Kenya.

Human excreta (faeces and urine) contribute only a small volume in domestic wastewater but are one of the main causes of water pollution. On the other hand, they contain very valuable nutrients to be reused as anthropogenic fertiliser through proper collection, treatment and hygienisation processes. To know the potential of nutrient recovery and reuse in Indonesia, a pilot scale source separation domestic wastewater system has been built in Surabaya and, so far, has shown promising results. Using urine diverting toilets, up to 86% nitrogen, 21% phosphorus and 69% potassium from urine and 12% of nitrogen, 68% of phosphorus and 20% of potassium from the faecal matter can be recovered. The separated urine was stored for 6 months before usage as fertiliser for hygienic reasons, while the separated faecal matter was composted with worms (vermicomposting). In order to investigate the fertilising effect, a preliminary cultivation experiment has been carried out on young rose plants using different fertilisers for 2 months.

Medical providers may face unique emotional challenges when confronted with the suffering of chronically ill, dying, and bereaved children. This study assessed the preliminary outcomes of participation in a group-based multimodal mindfulness training pilot designed to reduce symptoms of burnout and mental health symptoms in providers who interact with children in the context of end-of-life care. A total of 13 medical providers who care for children facing life-threatening illness or bereaved children participated in a 9-session multimodal mindfulness session. Mental health symptoms and burnout were assessed prior to the program, at the program midpoint, and at the conclusion of the program. Participation in the pilot was associated with significant reductions in depressive and posttraumatic stress disorder (PTSD) symptoms among providers ( P < .05). Mindfulness-based programs may help providers recognize and address symptoms of depression and PTSD. Additional research is needed to enhance access and uptake of programming among larger groups of participants.

Solvent-free microwave extraction (SFME) has been proposed as a green method for the extraction of essential oil from aromatic herbs that are extensively used in the food industry. This technique is a combination of microwave heating and dry distillation performed at atmospheric pressure without any added solvent or water. The isolation and concentration of volatile compounds is performed in a single stage. In this work, SFME and a conventional technique, hydro-distillation HD (Clevenger apparatus), are used for the extraction of essential oil from rosemary (Rosmarinus officinalis L.) and are compared. This preliminary laboratory study shows that essential oils extracted by SFME in 30min were quantitatively (yield and kinetics profile) and qualitatively (aromatic profile) similar to those obtained using conventional hydro-distillation in 2h. Experiments performed in a 75L pilot microwave reactor prove the feasibility of SFME up scaling and potential industrial applications. Copyright © 2013 Elsevier Ltd. All rights reserved.

Taking the first step towards entrenching mental health in the workplace: insights from a pilot study among HR personnel in Nigeria.

The continued relevance of optimal employee mental health to sustainable human capital development in the workplace underscores the need to start harnessing all resources that can be mobilized to promote the entrenchment of workplace mental health. The strategic place of workplace Human Resource (HR) units in formulating and implementing workplace welfare schemes makes them potential partners. To actualize this, it is important to initially assess the preparedness of HR personnel for, and the possible barriers to entrenching mental health in the workplace. To suggest the initial course of action and to serve as a template for a robust large-scale study, we conduct a pilot assessment of the experience with, attitudes towards, and level of prioritization of mental health in the workplace among a cohort of HR personnel in Nigeria. Participants were recruited in the course of a seminar/workshop and questionnaires were developed by authors to assess variables of interest. Attitudes were examined using an adapted form of the Link's Discrimination-Devaluation (LD-D) scale. A total of 90 human-resource personnel completed the questionnaires. Only 16% of the participants reported having handled the case of an employee with a suspected mental health problem in the preceding 2 years. Attitudes toward employees and prospective employees with mental illness were largely poor. For instance, more than 70% were likely to consider for employment someone with a pre-existing physical disability than for someone with a history of mental illness. In terms of workplace health promotion priorities, physical health seminars took wide precedence over mental health seminars. The preliminary findings of this pilot study justify a need to conduct a large scale study. Significant challenges encountered in the course of this pilot study were highlighted while insights were drawn for the conduct of the main study/project.

OBJECTIVES. Executive functioning deficits may result from concussion. The Charge of Quarters (CQ) Duty Task is a multitask assessment designed to assess executive functioning in servicemembers after concussion. In this article, we discuss the rationale and process used in the development of the CQ Duty Task and present pilot data from the preliminary evaluation of interrater reliability (IRR). METHOD. Three evaluators observed as 12 healthy participants performed the CQ Duty Task and measured performance using various metrics. Intraclass correlation coefficient (ICC) quantified IRR. RESULTS. The ICC for task completion was .94. ICCs for other assessment metrics were variable. CONCLUSION. Preliminary IRR data for the CQ Duty Task are encouraging, but further investigation is needed to improve IRR in some domains. Lessons learned in the development of the CQ Duty Task could benefit future test development efforts with populations other than the military.

This study investigates the use of dropped neck flexion as a manoeuvre to test the restrictive abilities of two different types of soft collars, an Airway soft cervical collar and a handmade cervical rough. The range of neck flexion of 40 asymptomatic subjects aged 20-29 was assessed, both with and without collar wear, using a Spinal Rangiometer. Dropped neck flexion is described as possibly being more representative of the type of movement that a patient with neck pain will undergo, and hence a more useful manoeuvre to employ when testing for the restrictive abilities of soft cervical collars. The mean dropped flexion was 64 degrees without collar wear, 58 degrees with the Airway soft collar, and 34 degrees with the cervical rough. Only the cervical rough provided both statistically (p < 0.001) and clinically (> 15°) significant restriction of dropped neck flexion. The comfort, preparation time, and ease of application of each of these collars is not addressed in this study, and may reflect on use in clinical practice. This preliminary study provides insight and pilot data for future studies in this area. ImagesFigure 2Figure 3

As part of NASA's Aviation Safety and Security Program, a simulation study of a twinjet transport airplane crew training simulation was conducted to address fidelity for upset or loss of control conditions and to study the effect of flap configuration in those regimes. Piloted and desktop simulations were used to compare the baseline crew training simulation model with an enhanced aerodynamic model that was developed for high-angle-of-attack conditions. These studies were conducted with various flap configurations and addressed the approach-to-stall, stall, and post-stall flight regimes. The enhanced simulation model showed that flap configuration had a significant effect on the character of departures that occurred during post-stall flight. Preliminary comparisons with flight test data indicate that the enhanced model is a significant improvement over the baseline. Some of the unrepresentative characteristics that are predicted by the baseline crew training simulation for flight in the post-stall regime have been identified. This paper presents preliminary results of this simulation study and discusses key issues regarding predicted flight dynamics characteristics during extreme upset and loss-of-control flight conditions with different flap configurations.

The direction of future spatial disorientation (SD) research and training is shaped primarily by the outcome of formal investigation of aircraft accidents and incidents. However, another source of vital information is aircrews' experience of SD that does not result in reported incidents. A short postal SD survey was distributed to 5 Naval Air Squadrons, 22 Joint Helicopter Command Units, and 7 Royal Air Force stations in the United Kingdom. There were 752 questionnaires, including responses from 562 pilots and 149 navigators, that were returned. Analysis was conducted primarily on the pilot data. The most frequently experienced SD episodes were "the leans" (by 92% of respondents), loss of horizon due to atmospheric conditions (82%), misleading altitude cues (79%), sloping horizon (75%), and SD arising from distraction (66%). In general, the frequency of SD episodes and ratings of severity of the worst ever SD episode were positively related to flying experience (p < 0.05). Overall, pilots who had received in-flight SD training reported more episodes of SD than those who had not participated in this training (p < 0.05). Differences in types of SD experienced were found between aircraft categories, e.g., more episodes of SD during night vision goggle use were reported by rotary-wing pilots compared with fast-jet aviators (p < 0.05). This preliminary survey has shown that SD is still a significant hazard of military flying. Overall, this study shows that the postal questionnaire is a useful tool for assessing how SD training and experience may benefit the recognition of situations that may cause SD. However, it is difficult to access those situations where aircrew were truly disorientated.
