    2002-04-01

    General Aviation (GA) cross-country crashes, particularly those involving weather, continue to be a major source of fatalities, with a fatality rate more than four times greater than for GA crashes in general. There has been much speculation and little solid evidence on the causes of these crashes. We have designed a program of laboratory and database research into the causes of cross-country weather-related crashes including an analysis of air crashes in New Zealand between 1988 and 2000. There were 1308 reported occurrences in this period. We examined in detail 77 crashes where it could be determined that the aircraft was on a cross-country flight. In our first analysis we compared the characteristics of crashes that occurred in response to externally driven failures with crashes where the aircraft continued to be flown at the pilot's discretion up until the point of the crash. Clear differences were found for visibility, altitude, crash severity, and for several pilot characteristics. These differences are highly consistent with those found for previous research on pilot characteristics and crash involvement. In the second analysis we made comparisons between the weather-related and nonweather-related crashes in the discretionary control group and between subcategories of weather-related crashes. These data show that weather-related crashes occur further into the flight and closer to the planned destination than other kinds of cross-country crashes in GA. Pilots involved in these crashes are younger and have more recent flight time than pilots involved in other crashes. Their increased involvement cannot be explained simply by exposure (flight-time) but must be due to other factors.

  5. The role of situation assessment and flight experience in pilots' decisions to continue visual flight rules flight into adverse weather.

    Science.gov (United States)

    Wiegmann, Douglas A; Goh, Juliana; O'Hare, David

    2002-01-01

    Visual flight rules (VFR) flight into instrument meteorological conditions (IMC) is a major safety hazard in general aviation. In this study we examined pilots' decisions to continue or divert from a VFR flight into IMC during a dynamic simulation of a cross-country flight. Pilots encountered IMC either early or later into the flight, and the amount of time and distance pilots flew into the adverse weather prior to diverting was recorded. Results revealed that pilots who encountered the deteriorating weather earlier in the flight flew longer into the weather prior to diverting and had more optimistic estimates of weather conditions than did pilots who encountered the deteriorating weather later in the flight. Both the time and distance traveled into the weather prior to diverting were negatively correlated with pilots' previous flight experience. These findings suggest that VFR flight into IMC may be attributable, at least in part, to poor situation assessment and experience rather than to motivational judgment that induces risk-taking behavior as more time and effort are invested in a flight. Actual or potential applications of this research include the design of interventions that focus on improving weather evaluation skills in addition to addressing risk-taking attitudes.

  7. Urban tourism: the growing role of VFR and immigration

    Directory of Open Access Journals (Sweden)

    Tom Griffin

    2017-09-01

    Full Text Available Purpose – The purpose of this paper is to offer some insights into the future of urban tourism with particular consideration given to immigration and visiting friends and relatives (VFR travel. The discussion highlights the fact that cities are increasingly home to immigrants and transitory residents who host visitors, blurring resident-visitor distinctions, with implications for cultural and economic development, and tourism practitioners. These trends are highlighted, and discussions relating to the future are offered. Design/methodology/approach – This discussion is based on a literature review and a conceptual approach. Findings – The number of immigrants to cities keeps growing. These immigrants are shaping their new communities and changing local culture. They contribute to increased tourism through generating VFR travel and creating new tourist attractions. Research limitations/implications – The implications of VFR and immigration on urban tourism are most visible in large urban centers that are major points of entry into a country and international magnets. They are not, however, limited to big cities. Practical implications – There are potential implications for municipal governments and destination marketers to consider how cultural development and the touristic promotion of the city overlap with areas and direction for possible partnerships with community groups. Social implications – This paper promotes the idea that for immigrants, to experience their communities through hosting VFR has positive social implications in terms of integration and cultural development. Originality/value – This paper discusses a topic rarely addressed the impact of VFR and immigration on shaping urban tourism.

  8. Identification of the Staphylococcus aureus vfrAB operon, a novel virulence factor regulatory locus.

    2014-05-01

    During a screen of the Nebraska Transposon Mutant Library, we identified 71 mutations in the Staphylococcus aureus genome that altered hemolysis on blood agar medium. Although many of these mutations disrupted genes known to affect the production of alpha-hemolysin, two of them were associated with an apparent operon, designated vfrAB, that had not been characterized previously. Interestingly, a ΔvfrB mutant exhibited only minor effects on the transcription of the hla gene, encoding alpha-hemolysin, when grown in broth, as well as on RNAIII, a posttranscriptional regulatory RNA important for alpha-hemolysin translation, suggesting that VfrB may function at the posttranscriptional level. Indeed, a ΔvfrB mutant had increased aur and sspAB protease expression under these conditions. However, disruption of the known secreted proteases in the ΔvfrB mutant did not restore hemolytic activity in the ΔvfrB mutant on blood agar. Further analysis revealed that, in contrast to the minor effects of VfrB on hla transcription when strains were cultured in liquid media, the level of hla transcription was decreased 50-fold in the absence of VfrB on solid media. These results demonstrate that while VfrB represses protease expression when strains are grown in broth, hla regulation is highly responsive to factors associated with growth on solid media. Intriguingly, the ΔvfrB mutant displayed increased pathogenesis in a model of S. aureus dermonecrosis, further highlighting the complexity of VfrB-dependent virulence regulation. The results of this study describe a phenotype associated with a class of highly conserved yet uncharacterized proteins found in Gram-positive bacteria, and they shed new light on the regulation of virulence factors necessary for S. aureus pathogenesis.

  15. VfrB Is a Key Activator of the Staphylococcus aureus SaeRS Two-Component System.

    Science.gov (United States)

    Krute, Christina N; Rice, Kelly C; Bose, Jeffrey L

    2017-03-01

    In previous studies, we identified the fatty acid kinase virulence factor regulator B (VfrB) as a potent regulator of α-hemolysin and other virulence factors in Staphylococcus aureus In this study, we demonstrated that VfrB is a positive activator of the SaeRS two-component regulatory system. Analysis of vfrB , saeR , and saeS mutant strains revealed that VfrB functions in the same pathway as SaeRS. At the transcriptional level, the promoter activities of SaeRS class I ( coa ) and class II ( hla ) target genes were downregulated during the exponential growth phase in the vfrB mutant, compared to the wild-type strain. In addition, saePQRS expression was decreased in the vfrB mutant strain, demonstrating a need for this protein in the autoregulation of SaeRS. The requirement for VfrB-mediated activation was circumvented when SaeS was constitutively active due to an SaeS (L18P) substitution. Furthermore, activation of SaeS via human neutrophil peptide 1 (HNP-1) overcame the dependence on VfrB for transcription from class I Sae promoters. Consistent with the role of VfrB in fatty acid metabolism, hla expression was decreased in the vfrB mutant with the addition of exogenous myristic acid. Lastly, we determined that aspartic acid residues D38 and D40, which are predicted to be key to VfrB enzymatic activity, were required for VfrB-mediated α-hemolysin production. Collectively, this study implicates VfrB as a novel accessory protein needed for the activation of SaeRS in S. aureus IMPORTANCE The SaeRS two-component system is a key regulator of virulence determinant production in Staphylococcus aureus Although the regulon of this two-component system is well characterized, the activation mechanisms, including the specific signaling molecules, remain elusive. Elucidating the complex regulatory circuit of SaeRS regulation is important for understanding how the system contributes to disease causation by this pathogen. To this end, we have identified the fatty acid kinase

    2017-04-01

    In aviation psychology, there is a constant need for the cognitive evaluation of pilots as part of operational fitness and safety criteria. A cross-sectional study with comparison between the performance of Israeli Air Force pilot cadets (N = 318) and U.S. Air Force pilot training candidates (N = 512) as assessed by a cognitive battery was undertaken. The data of the comparison group was collected from Callister, King, and Retzlaff, as published in 1996. In general, the means in the three components composing the battery-speed, accuracy, and throughput variables-indicated that the Israeli Air Force pilot cadets' scores were higher than those of the U.S. Air Force pilot candidates' scores in 50 of 53 variables. Nonsignificant differences were found in Accuracy of shifting attention-arrow color (SATAC), pathfinder-combined (PFC), and pathfinder-letter (PFL). The difference in performance between the two groups may be due to differences in population characteristics. However, these results need to be considered cautiously, as the groups were sampled at a sizeable time gap (1996 for the U.S. Air Force vs. 2013 for the Israeli Air Force), with each time period characterized by different cultural and technological influences.Gordon S, Goren C, Carmon E, Shelef L.

  2. An evaluation of the management system verification pilot at Hanford

    International Nuclear Information System (INIS)

    Briggs, C.R.; Ramonas, L.; Westendorf, W.

    1998-01-01

    The Chemical Management System (CMS), currently under development at Hanford, was used as the ''test program'' for pilot testing the value added aspects of the Chemical Manufacturers Association's (CMA) Management Systems Verification (MSV) process. The MSV process, which was developed by CMA's member chemical companies specifically as a tool to assist in the continuous improvement of environment, safety and health (ESH) performance, represents a commercial sector ''best practice'' for evaluating ESH management systems. The primary purpose of Hanford's MSV Pilot was to evaluate the applicability and utility of the MSV process in the Department of Energy (DOE) environment. However, because the Integrated Safety Management System (ISMS) is the framework for ESH management at Hanford and at all DOE sites, the pilot specifically considered the MSV process in the context of a possible future adjunct to Integrated Safety Management System Verification (ISMSV) efforts at Hanford and elsewhere within the DOE complex. The pilot involved the conduct of two-hour interviews with four separate panels of individuals with functional responsibilities related to the CMS including the Department of Energy Richland Operations (DOE-RL), Fluor Daniel Hanford (FDH) and FDH's major subcontractors (MSCS). A semi-structured interview process was employed by the team of three ''verifiers'' who directed open-ended questions to the panels regarding the development, integration and effectiveness of management systems necessary to ensure the sustainability of the CMS effort. An ''MSV Pilot Effectiveness Survey'' also was completed by each panel participant immediately following the interview

    2010-05-01

    Full Text Available Abstract Background In healthcare today, decisions are made in the face of serious resource constraints. Healthcare managers are struggling to provide high quality care, manage resources effectively, and meet changing patient needs. Healthcare managers who are constantly making difficult resource decisions desire a way to improve their priority setting processes. Despite the wealth of existing priority setting literature (for example, program budgeting and marginal analysis, accountability for reasonableness, the 'describe-evaluate-improve' strategy there are still no tools to evaluate how healthcare resources are prioritised. This paper describes the development and piloting of a process to evaluate priority setting in health institutions. The evaluation process was designed to examine the procedural and substantive dimensions of priority setting using a multi-methods approach, including a staff survey, decision-maker interviews, and document analysis. Methods The evaluation process was piloted in a mid-size community hospital in Ontario, Canada while its leaders worked through their annual budgeting process. Both qualitative and quantitative methods were used to analyze the data. Results The evaluation process was both applicable to the context and it captured the budgeting process. In general, the pilot test provided support for our evaluation process and our definition of success, (i.e., our conceptual framework. Conclusions The purpose of the evaluation process is to provide a simple, practical way for an organization to better understand what it means to achieve success in its priority setting activities and identify areas for improvement. In order for the process to be used by healthcare managers today, modification and contextualization of the process are anticipated. As the evaluation process is applied in more health care organizations or applied repeatedly in an organization, it may become more streamlined.

    The primary focus of the BDBE pilot project was the review of BDBE analysis and mitigation features at four DOE nuclear facilities representing a range of DOE sites, nuclear facility types/activities, and responsible program offices. The pilots looked at (1) how beyond design basis accidents were evaluated and documented in the facility Documented Safety Analysis, (2) potential BDBE vulnerabilities and margins to failure of facility safety features as obtained from general area and specific system walkdowns and design documents reviews, and (3) preparations made in facility and site emergency management programs to respond to severe accidents. It also evaluated whether draft BDBE guidance on safety analysis and emergency management could be used to improve the analysis of and preparations for mitigating severe and beyond design basis accidents. The details of these activities are organized in this report as described below.

    Imported diseases recorded in the European Union (EU) increasingly involve traveling immigrants returning from visits to their relatives and friends (VFR). Children of these immigrant families can represent a population of extreme vulnerability. A randomized cross-sectional study of 698 traveling children under the age of 15 was performed. VFR traveling children and non-VFR (or tourist) children groups were compared. A total of 698 individuals were analyzed: 354 males (50.7%) and 344 females (49.3%), with a median age (interquartile range) of 4 (2-9) years. Of these, 578 (82.8%) had been born in the EU with 542 (77.7%) being considered as VFR, whereas 156 (22.3%) were considered tourists. VFR children were younger (4.7 vs 8.2 yr; p travel time interval was shorter (21.8 vs 32.2 d; p traveling children showed a greater risk of exposure to infectious diseases compared with tourists. Immigrant families may represent a target group to prioritize international preventive activities. © 2011 International Society of Travel Medicine.

    2015-01-01

    infection give rise to rugose small colony variants (RSCVs), which are hyper-biofilm-forming mutants that commonly possess mutations that increase production of the biofilm-promoting secondary messenger cyclic di-GMP (c-di-GMP). We show that RSCVs display a decreased production of acute virulence factors...... as a direct result of elevated c-di-GMP content. Overproduction of c-di-GMP causes a decrease in the transcription of virulence factor genes that are regulated by the global virulence regulator Vfr. The low level of Vfr-dependent transcription is caused by a low level of its coactivator, cyclic AMP (c......AMP), which is decreased in response to a high level of c-di-GMP. Mutations that cause reversion of the RSCV phenotype concomitantly reactivate Vfr-cAMP signaling. Attempts to uncover the mechanism underlying the observed c-di-GMP-mediated lowering of cAMP content provided evidence that it is not caused...

  13. A qualitative evaluation of a pilot leadership programme for dentists.

    2015-07-06

    The purpose of this paper was to evaluate a pilot training programme run by Health Education North West to promote clinical leadership amongst general dental practitioners (GDPs). New powers and responsibilities for clinicians have caused a fundamental shift in the way that local services are planned and delivered in England. GDPs are being appointed onto the boards of local professional networks (LPNs) to influence the way that services are delivered at a local level. Analogous to clinical commissioning groups in medicine, the role of LPNs is to ensure that GDPs lead change and drive up the quality of service provision. Clinical leadership has been argued to be fundamentally important in these new structures, but has received little attention in the dental literature. Semi-structured interviews and a focus group were held with participants of the pilot to explore their understanding and experience of clinical leadership. These were recorded, transcribed verbatim and underwent thematic analysis. Nineteen codes were identified and organized into four themes: nature of clinical leadership, challenges for clinical leaders in dentistry, Leadership Exploration and Discovery programme evaluation and future direction. The research provides an understanding of how GDPs conceptualise clinical leadership and provides recommendations for future leadership training programmes. This is the first evaluation of a leadership programme for GDPs and so helps address the paucity of evidence in the dental literature.

  14. Annual stability evaluation of Waste Isolation Pilot Plant

    International Nuclear Information System (INIS)

    1993-06-01

    A stability evaluation of the underground workings of the Waste Isolation Pilot Plant (WIPP) was completed by the US Bureau of Mines' WIPP evaluation committee. This work included a critical evaluation of the processes employed at WIPP to ensure stability, an extensive review of available deformation measurements, a 3-day site visit, and interviews with the Department of Energy (DOE) and Westinghouse staff. General ground control processes are in place at WIPP to minimize the likelihood that major stability problems will go undetected. To increase confidence in both short- and long-term stability throughout the site (underground openings and shafts), ground stability monitoring systems, mine layout design, support systems and data analyses must be continuously improved. Such processes appear to be in place at WIPP and are discussed in this paper

  15. Pilot Domain Task Experience in Night Fatal Helicopter Emergency Medical Service Accidents.

    Aherne, Bryan B; Zhang, Chrystal; Newman, David G

    2016-06-01

    In the United States, accident and fatality rates in helicopter emergency medical service (HEMS) operations increase significantly under nighttime environmentally hazardous operational conditions. Other studies have found pilots' total flight hours unrelated to HEMS accident outcomes. Many factors affect pilots' decision making, including their experience. This study seeks to investigate whether pilot domain task experience (DTE) in HEMS plays a role against likelihood of accidents at night when hazardous operational conditions are entered. There were 32 flights with single pilot nighttime fatal HEMS accidents between 1995 and 2013 with findings of controlled flight into terrain (CFIT) and loss of control (LCTRL) due to spatial disorientation (SD) identified. The HEMS DTE of the pilots were compared with industry survey data. Of the pilots, 56% had ≤2 yr of HEMS experience and 9% had >10 yr of HEMS experience. There were 21 (66%) accidents that occurred in non-visual flight rules (VFR) conditions despite all flights being required to be conducted under VFR. There was a statistically significant increase in accident rates in pilots with pilots with >10 yr HEMS DTE. HEMS DTE plays a preventive role against the likelihood of a night operational accident. Pilots with limited HEMS DTE are more likely to make a poor assessment of hazardous conditions at night, and this will place HEMS flight crew at high risk in the VFR night domain.

Text4baby is an example of mobile health based on behavioral theory, and it delivers text messages to traditionally underserved pregnant women and new mothers to change their health, health care beliefs, practices, and behaviors in order to improve clinical outcomes. The purpose of this pilot evaluation study is to assess the efficacy of this text messaging campaign. Methods We conducted a randomized pilot evaluation study. All participants were pregnant women first presenting for care at the Fairfax County, Virginia Health Department. We randomized participants to enroll in text4baby and receive usual health care (intervention, or continue simply to receive usual care (control. We then conducted a 24-item survey by telephone of attitudes and behaviors related to text4baby. We surveyed participants at baseline, before text4baby was delivered to the intervention group, and at follow-up at approximately 28 weeks of baby’s gestational age. Results We completed 123 baseline interviews in English and in Spanish. Overall, the sample was predominantly of Hispanic origin (79.7% with an average age of 27.6 years. We completed 90 follow-up interviews, and achieved a 73% retention rate. We used a logistic generalized estimating equation model to evaluate intervention effects on measured outcomes. We found a significant effect of text4baby intervention exposure on increased agreement with the attitude statement “I am prepared to be a new mother” (OR = 2.73, CI = 1.04, 7.18, p = 0.042 between baseline and follow-up. For those who had attained a high school education or greater, we observed a significantly higher overall agreement to attitudes against alcohol consumption during pregnancy (OR = 2.80, CI = 1.13, 6.90, p = 0.026.

    Malaria is a notifiable disease in the Netherlands, a non-endemic country. Imported malaria infections occur regularly among travellers, migrants and visitors. Surveillance data were analysed from 2008 to 2015. Trends in amounts of notifications among risk groups were analysed using Poisson regression. For asylum seekers, yearly incidence was calculated per region of origin, using national asylum request statistics as denominator data. For tourists, denominator data were used from travel statistics to estimate incidence per travel region up to 2012. A modest increase in overall imported malaria notifications occurred in 2008-2015 (from 222 in 2008 to 344 in 2015). Notably, in 2014 and 2015 sharp increases were seen in malaria among travellers visiting friends and relatives (VFR), and in asylum seekers. Of all Plasmodium falciparum infections, most (1254/1337; 93.8%) were imported from Africa; 1037/1337 (77.6%) were imported from Central and West Africa. Malaria in VFR was mostly caused by P. falciparum infection after visiting Ghana (22%) or Nigeria (19%). Malaria in asylum seekers was mostly caused by Plasmodium vivax infection from the Horn of Africa. The large number of notifications in asylum seekers resulted from both an increase in number of asylum seekers and a striking increase of malaria incidence in this group. Incidence of malaria in asylum seekers from the Horn of Africa ranged between 0.02 and 0.3% in 2008-2013, but rose to 1.6% in 2014 and 1.3% in 2015. In 2008-2012, incidence in tourists visiting Central and West Africa dropped markedly. Imported malaria is on the rise again in the Netherlands, most notably since 2013. This is mostly due to immigration of asylum seekers from the Horn of Africa. The predominance of P. vivax infection among asylum seekers warrants vigilance in health workers when a migrant presents with fever, as relapses of this type of malaria can occur long after arrival in the Netherlands.

    Environmental auditing is an important tool to ensure consistent and effective cleaning. Our pilot study compared an alcohol-based fluorescent marking product and an adenosine-5'-triphosphate bioluminescence product for use in an environmental auditing program to determine which product was more practical and acceptable to users. Both products were tested on 15 preselected high touch objects in randomly selected patient rooms, following regular daily cleaning. A room was considered a "pass" if ≥80% of surfaces were adequately cleaned as defined by manufacturers' guidelines. A qualitative survey assessed user preference and operational considerations. Using fluorescent marking, 9 of 37 patient rooms evaluated (24%) were considered a "pass" after daily cleaning. Using adenosine-5'-triphosphate bioluminescence, 21 of 37 patient rooms passed (57%). There was great variability in results between different high touch objects. Eighty percent of users preferred the alcohol-based fluorescent marking product because it provided an effective visual aid to coach staff on proper cleaning techniques and allowed simple and consistent application. Environmental auditing using translucent, alcohol-based fluorescent marking best met the requirements of our organization. Our results reinforce the importance of involving a multidisciplinary team in evaluating and operationalizing an environmental auditing program.

    2014-06-01

    A new construction pilot community was constructed by builder-partner Wathen-Castanos Hybrid Homes (WCHH) based on a single occupied test house that was designed to achieve greater than 30% energy savings with respect to the House Simulation Protocols (Hendron, Robert; Engebrecht, Cheryn (2010). Building America House Simulation Protocols. Golden, CO: National Renewable Energy Laboratory). Builders face several key problems when implementing a whole-house systems integrated measures package (SIMP) from a single test house into multiple houses. Although a technical solution already may have been evaluated and validated in an individual test house, the potential exists for constructability failures at the community scale. This report addresses factors of implementation and scalability at the community scale and proposes methodologies by which community-scale energy evaluations can be performed based on results at the occupied test house level. Research focused on the builder and trade implementation of a SIMP and the actual utility usage in the houses at the community scale of production. Five occupants participated in this community-scale research by providing utility bills and information on occupancy and miscellaneous gas and electric appliance use for their houses. IBACOS used these utility data and background information to analyze the actual energy performance of the houses. Verification with measured data is an important component in predictive energy modeling. The actual utility bill readings were compared to projected energy consumption using BEopt with actual weather and thermostat set points for normalization.

    Full Text Available Podcasting has become a popular means of transferring knowledge in higher education through making lecture contents available to students at their convenience. Accessing courses on media players provides students with enhanced learning opportunities. Development of teaching methods able to cope with ever-changing nature of medicine is crucial to train the millennium students. Pharmacology education in Tehran University of Medical Sciences has been based on lectures so far; our aim was to implement a pilot study to evaluate the advantages and disadvantages of offering the course contents as podcasts as well as evaluating whether such program can be feasible in our educational program. 46% of students downloaded the podcast according to our download center. 48% favored usage of both internet and DVD-ROM concurrently. Overall 96% of students perceived that podcasting had a positive impact on their learning in pharmacology course. Our results indicate that most of attendants proposed the positive yields of podcasting despite low usage of it, mainly as a pre-class preparing tool.

    The EES pilot program was initiated in August 1977, when 10 states were selected on a competitive basis for participation. The pilot states (Alabama, Connecticut, Michigan, New Mexico, Pennsylvania, Tennessee, Texas, Washington, Wisconsin, and Wyoming) devoted the first 6 months to start-up activities. This document is a follow-up report to the three volume Evaluation Summary of the first year of the pilot EES program published in September 1979. The purpose of this report is to provide an overview of the impacts and costs of the two years of the pilot program, and to check the consistency of findings over the two year period. The analysis addresses the following: (1) were the impact findings of Year I and Year II consistent, or did Year I and Year II attitudes and behavior vary. If variation existed, could it be attributed to program changes as the EES progressed from a start-up phase (Year I) to more normal service delivery (Year II); and (2) did costs of service delivery change (again reflecting start-up and normal service delivery costs). Did cost changes affect conclusions about the relative cost effectiveness of delivering services to different target audiences.

    With a priority programme the German Cancer Aid supported the development of quality-assured outpatient palliative care to cover the whole country. The 12 regional pilot projects funded with the aim to improve outpatient palliative care in different models and different frameworks were concurrently monitored and evaluated. The supported projects, starting and ending individually, documented all patients who were cared for using HOPE (Hospice and palliative care evaluation) and MIDOS (Minimal documentation system for palliative patients). Total data were analyzed for 3239 patients decriptively. In addition to the quantitative data the experiences of the projects were recorded in a number of workshops (2008, 2009, 2010, and 2012). In particular, the experiences reported in the final meeting in July 2012 were considered for this article as well as the final reports for the German Cancer Aid. In the quantitative evaluation 85.6% of 3239 palliative care patients had a cancer diagnosis. In all model projects the goal of a network with close cooperation of primary providers, social support, and outpatient and inpatient specialist services has been achieved. For all projects, the initial financing of the German Cancer Aid was extremely important, because contracts with health insurance funds were negotiated slowly, and could then be built on the experiences with the projects. The participants of the project-completion meeting emphasized the need to carry out a market analysis before starting palliative care organizations considering the different regional structures and target groups of patients. Education, training and continuing education programs contribute significantly to the network. A reliably funded coordination center/case management across all institutions is extremely important. © Georg Thieme Verlag KG Stuttgart · New York.

    Violence has recently been reported among a primarily young, minority population in Nashville, Tennessee. School-based programs have been proven as effective methods of reducing violent behavior, beliefs, and actions that lead to violence among adolescents. Investigators implemented a rigorous search for an appropriate school-based violence prevention program for Metropolitan Nashville middle school students utilizing a systematic review and discussion group with victims of violence. 27 programs nation-wide were reviewed and 2 discussion groups with African American males under the age of 25 admitted to a level 1 trauma center for assault-related injuries were conducted. Our findings led to a single, evidence-based conflict resolution program. In conjunction with educators, we evaluated the program's effectiveness in a pilot study in a Nashville middle school with high rates of violence. 122 students completed the conflict resolution program and described their behavior and experiences with violence in a pre-test/post-test self-rate questionnaire. Results showed a significant decrease in violent behavior and an increase in students' competencies to deal with violence (p less than 0.05). This study shows that a reduction in violent behavior and beliefs among middle school students can be achieved through the implementation of a targeted violence intervention program. A larger-scale intervention is needed to develop more conclusive evidence of effectiveness. © 2015 KUMS, All rights reserved.

Main goal of the study is collecting evidence for program optimization. A controlled study was carried out with repeated measurement before and after the intervention (4-6 months. Multilevel analyses, ANCOVA, and logistic regression analyses were applied to measure the effects. Overall, significantly lower incidence rates of drunkenness (odds ratio [OR] = .55; p = .033, improved knowledge about psychoactive substances (p = .006, lower personal (p = .013 and general tobacco risk perception among users (p = .002, and lower general tobacco (p = .018 and cannabis (p = .000 risk perception in non-users were found in the total intervention group. In subgroups, significantly lower rates for the incidence of drunkenness can be shown for males (p = .008 and for younger participants (p = .004. Students at academic high school (German Gymnasium showed a decrease in 30-day prevalence for alcohol (p = .017 and cannabis (p = .014, and they improved in their knowledge about psychoactive substances (p = .000. In vocational high school classes (German Realschule, there was an increase in the relative alcohol risk perception of the students (p = .019. REBOUND contributes to a controlled use of alcohol and increases knowledge about psychoactive substances. REBOUND has various effects on the examined subgroups age, gender, and school type: Males, younger students, and students in academic high school benefitted more from the course regarding consumption-related criteria. We suggest a program optimization specific to school form and age, inclusion of a tobacco intervention, and the use of more gender-segregated interventions.

    When deriving an objective assessment of piloting performance from flight data records, it is common to employ metrics which purely evaluate errors in flight path parameters. The adequacy of pilot performance is evaluated from the flight path of the aircraft. However, in large jet transport aircraft these measures may be insensitive and require supplementing with frequency-based measures of control input parameters. Flight path and control input data were collected from pilots undertaking a jet transport aircraft conversion course during a series of symmetric and asymmetric approaches in a flight simulator. The flight path data were analyzed for deviations around the optimum flight path while flying an instrument landing approach. Manipulation of the flight controls was subject to analysis using a series of power spectral density measures. The flight path metrics showed no significant differences in performance between the symmetric and asymmetric approaches. However, control input frequency domain measures revealed that the pilots employed highly different control strategies in the pitch and yaw axes. The results demonstrate that to evaluate pilot performance fully in large aircraft, it is necessary to employ performance metrics targeted at both the outer control loop (flight path) and the inner control loop (flight control) parameters in parallel, evaluating both the product and process of a pilot's performance.

    Corazón Sano y Feliz is a hypertension management intervention developed to address deficiencies in the management of hypertensive patients in Guatemala. From 2007 to 2009, Corazón Sano y Feliz was pilot-tested in the community of Mixco. Corazón Sano y Feliz comprises a clinical risk assessment and treatment component implemented primarily by nurses, and a health education component implemented by community health workers. To accomplish our secondary objective of determining Corazon Sano y Feliz's potential for change at the patient level, we implemented a one-group pretest-posttest study design to examine changes in clinical measures, knowledge and practices between baseline and the end of the 6-month intervention. Two nurses and one physician set up a hypertension clinic to manage patients according to risk level. Twenty-nine community health workers were trained in CVD risk reduction and health promotion and in turn led six educational sessions for patients. Comparing baseline and 6-month measures, the intervention achieved significant improvements in mean knowledge and behaviour (increase from 54.6 to 59.1 out of a possible 70 points) and significant reductions of mean systolic and diastolic blood pressure (27.2 and 7.7 mmHg), body mass index (from 26.5 to 26.2 kg/m(2)) and waist circumference (89.6-88.9 cm). In this pilot study we obtained preliminary evidence that this community-oriented hypertension management and health promotion intervention model was feasible and achieved significant reduction in risk factors. If scaled up, this intervention has the potential to substantially reduce CVD burden. © The Author 2015. Published by Oxford University Press. All rights reserved.

    A pilot rating scale was developed to describe the effects of transients in helicopter flight-control systems on safety-of-flight and on pilot recovery action. The scale was applied to the evaluation of hardovers that could potentially occur in the digital flight-control system being designed for a variable-stability UH-60A research helicopter. Tests were conducted in a large moving-base simulator and in flight. The results of the investigation were combined with existing airworthiness criteria to determine quantitative reliability design goals for the control system.

    Eating disorders are serious psychiatric illnesses that are often associated with poor quality of life and low long-term recovery rates. Peer mentor programs have been found to improve psychiatric symptoms and quality of life in other mental illnesses, and a small number of studies have suggested that eating disorder patients may benefit from such programs. The aim of this study is to assess the efficacy of a peer mentor program for individuals with eating disorders in terms of improving symptomatology and quality of life. Up to 30 individuals with a past history of an eating disorder will be recruited to mentor 30 individuals with a current eating disorder. Mentoring will involve 13 sessions (held approximately every 2 weeks), of up to 3 h each, over 6 months. This pilot proof-of-concept feasibility study will inform the efficacy of a peer mentoring program on improving eating disorder symptomatology and quality of life, and will inform future randomised controlled trials.

    The use of green roofs is gaining increased recognition in many countries as a solution that can be used to improve environmental quality and reduce runoff quantity. To achieve these goals, pilot-scale green roof assemblies have been constructed and operated in an urban setting. From a stormwater management perspective, green roofs are 42.8-60.8% effective in reducing runoff for 200 mm soil depth and 13.8-34.4% effective in reducing runoff for 150 mm soil depth. By using Spearman rank correlation analysis, high rainfall intensity was shown to have a negative relationship with delayed occurrence time, demonstrating that the soil media in green roofs do not efficiently retain rainwater. Increasing the number of antecedent dry days can help to improve water retention capacity and delay occurrence time. From the viewpoint of runoff water quality, green roofs are regarded as the best management practice by filtration and adsorption through growth media (soil). Copyright © 2015 Elsevier Ltd.

    2000-01-01

    In 1990, the province of Quebec adopted a law authorizing the evaluation of the practice of midwifery through eight pilot projects. The projects, which took the form of birth centres outside hospitals, started operating in 1994. The objectives of the evaluation were 1) to compare midwives' services to current physician services with regard to maternal and neonatal mortality and morbidity, the use of obstetrical intervention, individualization and continuity of care as perceived by clients, and cost; and 2) to identify the professional and organizational factors associated with the integration of midwives into the health care system. A mixed evaluative design was used: a multiple case study with each pilot project representing a case and a cohort study where 1,000 women followed by midwives in the birth centres were matched with 1,000 women followed by physicians in the usual hospital-based services. Various quantitative and qualitative data collection instruments were used. Overall, many results were favourable to midwifery practice, while some were favourable to medical care. Following the evaluation, the Government of Quebec decided to legalize the practice of midwifery.

    The Training for Health Equity Network (THEnet), a group of diverse health professional schools aspiring toward social accountability, developed and pilot tested a comprehensive evaluation framework to assess progress toward socially accountable health professions education. The evaluation framework provides criteria for schools to assess their level of social accountability within their organization and planning; education, research and service delivery; and the direct and indirect impacts of the school and its graduates, on the community and health system. This paper describes the pilot implementation of testing the evaluation framework across five THEnet schools, and examines whether the evaluation framework was practical and feasible across contexts for the purposes of critical reflection and continuous improvement in terms of progress towards social accountability. In this pilot study, schools utilized the evaluation framework using a mixed method approach of data collection comprising of workshops, qualitative interviews and focus group discussions, document review and collation and analysis of existing quantitative data. The evaluation framework allowed each school to contextually gather evidence on how it was meeting the aspirational goals of social accountability across a range of school activities, and to identify strengths and areas for improvement and development. The evaluation framework pilot study demonstrated how social accountability can be assessed through a critically reflective and comprehensive process. As social accountability focuses on the relationship between health professions schools and health system and health population outcomes, each school was able to demonstrate to students, health professionals, governments, accrediting bodies, communities and other stakeholders how current and future health care needs of populations are addressed in terms of education, research, and service learning.

The pilot aimed to integrate care across primary, acute, community, mental health and social care for people with diabetes and those over 75 years through: care planning; multidisciplinary case reviews; information sharing; and project management support.   Methods: The evaluation team conducted qualitative studies of change at organisational, clinician, and patient levels (using interviews, focus groups and a survey; and quantitative analysis of change in service use and patient-level clinical outcomes (using patient-level data sets and a matched control study.  Results: The pilot had successfully engaged provider organisations, created a shared strategic vision and established governance structures. However, engagement of clinicians was variable and there was no evidence to date of significant reductions in emergency admissions. There was some evidence of changes in care processes. Conclusion: Although the pilot has demonstrated the beginnings of large-scale change, it remains in the early stages and faces significant challenges as it seeks to become sustainable for the longer term. It is critical that NHS managers and clinicians have realistic expectations of what can be achieved in a relatively short period of time.

    Full Text Available Purpose: This paper reports the findings of the evaluation of the Supporting People Health Pilots programme which was established to demonstrate the policy links between housing support services and health and social care services by encouraging the development of integrated services. The paper highlights the challenges of working across housing, health and social care boundaries. Method: The evaluation of the 6 health pilots rested on two main sources of data collection: Quarterly Project Evaluation Reports collected process data as well as reporting progress against aims and objectives. Semi-structured interviews - conducted across all key professional stakeholder groups and agencies and with people who used services - explored their experiences of these new services. Results: The ability of pilots to work across organisational boundaries to achieve their aims and objectives was associated not only with agencies sharing an understanding of the purpose of the joint venture, a history of joint working and clear and efficient governance arrangements but on two other characteristics: the extent and nature of statutory sector participation and, whether or not the service is defined by a history of voluntary sector involvement. In particular the pilots demonstrated how voluntary sector agencies appeared to be less constrained by organisational priorities and professional agenda and more able to respond flexibly to meet the complex needs of individuals. Conclusion and discussion: The pilots demonstrate that integrating services to support people with complex needs works best when the service is determined by the characteristics of those who use the service rather than pre-existing organisational structures.

    Care ethical theories provide an excellent opening for evaluation of healthcare practices since searching for (moments of) good care from a moral perspective is central to care ethics. However, a fruitful way to translate care ethical insights into measurable criteria and how to measure these criteria has as yet been unexplored: this study describes one of the first attempts. To investigate whether the emotional touchpoint method is suitable for evaluating care from a care ethical perspective. An adapted version of the emotional touchpoint interview method was used. Touchpoints represent the key moments to the experience of receiving care, where the patient recalls being touched emotionally or cognitively. Participants and research context: Interviews were conducted at three different care settings: a hospital, mental healthcare institution and care facility for older people. A total of 31 participants (29 patients and 2 relatives) took part in the study. Ethical considerations: The research was found not to be subject to the (Dutch) Medical Research Involving Human Subjects Act. A three-step care ethical evaluation model was developed and described using two touchpoints as examples. A focus group meeting showed that the method was considered of great value for partaking institutions in comparison with existing methods. Reflection and discussion: Considering existing methods to evaluate quality of care, the touchpoint method belongs to the category of instruments which evaluate the patient experience. The touchpoint method distinguishes itself because no pre-defined categories are used but the values of patients are followed, which is an essential issue from a care ethical perspective. The method portrays the insider perspective of patients and thereby contributes to humanizing care. The touchpoint method is a valuable instrument for evaluating care; it generates evaluation data about the core care ethical principle of responsiveness.

    Energy+ represents a European cooperative procurement initiative which aims at increasing the market share of highly energy-efficient cold appliances. Three years after its start, the project was recently evaluated in Germany. This paper discusses the main evaluation results and their implications for the project's further development. It covers the impacts of Energy+ on technology development and the commercial importance of the targeted appliances. Due to the project's relatively recent start, however, the main focus of the evaluation lies on the procurement process and practical implementation elements. Of particular interest are the specificities of the considered market segment which, in Germany and also in other participating countries, is characterised by highly dispersed consumers and the lack of large institutional buyers as candidates for a buyer group. The project therefore developed a new approach emphasising the role of retail organisations and of marketing activities by the project coordinators. The evaluation discusses several challenges related to this approach. This includes issues concerning the interfaces between international producers, their national branch offices and retailers as well as conflicts between the marketing approaches of producers and retailers, in particular with respect to the use of brand names and trade marks. Further, in Energy+ the communication between users and producers, an essential innovative element of cooperative procurement, cannot take its usual role, since consumers are not directly involved in the process. The paper shows how the project has dealt with these challenges and provides recommendations for the future project design

    Full Text Available Abstract Background MORE Energy is a mobile health intervention which aims to reduce fatigue and improve health in airline pilots. The primary objective of this process evaluation was to assess the reach, dose delivered, compliance, fidelity, barriers and facilitators, and satisfaction of the intervention. The second objective was to investigate the associations of adherence to the intervention with compliance and with participant satisfaction. Thirdly, we investigated differences between the subgroups within the target population. Methods The intervention consisted of a smartphone application, supported by a website. It provided advice on optimal light exposure, sleep, nutrition, and physical activity, tailored to flight and personal characteristics. The reach of the intervention was determined by comparing the intervention group participants and the airline pilots who did not participate. The dose delivered was defined as the total number of participants that was sent an instruction email. Objective compliance was measured through the Control Management System of the application. To determine the fidelity, an extensive log was kept throughout the intervention period. Subjective compliance, satisfaction, barriers, facilitators, and adherence were assessed using online questionnaires. Associations between the extent to which the participants applied the advice in daily life (adherence, compliance, and satisfaction were analysed as well. Finally, outcomes of participants of different age groups and haul types were compared. Results A total of 2222 pilots were made aware of the study.

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

    Full Text Available To encourage sustainable engineering practices, departments of transportation are interested in reusing winter maintenance truck wash water as part of their brine production and future road application. Traffic-related metals in the wash water, however, could limit this option. The objective of this work was to conduct a pilot scale evaluation of heavy metal (copper, zinc, iron, and lead removal in a filtration unit (maximum flow rate of 45 L/minute containing proprietary (MAR Systems Sorbster® media. Three different trials were conducted and approximately 10,000 L of wash water collected from a winter maintenance facility in Ohio was treated with the pilot unit. Lab studies were also performed on six wash-water samples from multiple facilities to assess particle size removal and estimate settling time as a potential removal mechanism during wash-water storage. Pilot unit total metal removal efficiencies were 79%, 77%, 63%, and 94% for copper, zinc, iron, and lead, respectively. Particle settling calculation estimates for copper and zinc show that 10 hours in storage can also effectively reduce heavy metal concentrations in winter maintenance wash water in excess of 70%. These pilot scale results show promise for reducing heavy metal concentrations to an acceptable level for reuse.

    Preliminary site selection activities for the WIPP are complete now; these consisted primarily of national and regional studies over the past fifteen years, and resulted in selection of the WIPP study area for geological characterization. The work of geological characterization should be considered to have begun with the drilling of ERDA 9 at the center of the WIPP study area and the initiation of seismic reflection work on the site. That geological characterization, which is primarily oriented to provide specific data concerning the present geology of the site, was virtually complete in December, 1978, when the Geological Characterization Report was submitted to the Department of Energy; much basic information has been gathered indicating no major technical problems with the site as it is now understood. Studies of long-term processes which might affect a repository or have an effect on safety analyses will now be the major geotechnical activity for the WIPP site evaluation team, some of these activities are already underway. These studies will deal with the age of significant features and the rates and processes which produce those features. The information so gained will be useful in increasing the confidence in evaluation of the safety of a repository

    Behavioral performance, subjective assessment based on NASA Task Load Index (NASA-TLX), as well as physiological measures indexed by electrocardiograph (ECG), event-related potential (ERP), and eye tracking data were used to assess the mental workload (MW) related to flight tasks. Flight simulation tasks were carried out by 12 healthy participants under different MW conditions. The MW conditions were manipulated by setting the quantity of flight indicators presented on the head-up display (HUD) in the cruise phase. In this experiment, the behavioral performance and NASA-TLX could reflect the changes of MW ideally. For physiological measures, the indices of heart rate variability (HRV), P3a, pupil diameter and eyelid opening were verified to be sensitive to MW changes. Our findings can be applied to the comprehensive evaluation of MW during flight tasks and the further quantitative classification.

    Acyclic vaginal bleeding in girls within three years of menarche is most commonly attributed to an immature hypothalamic-pituitary-ovarian axis. Assuming this diagnosis may preclude the practitioner from performing more definitive studies and thereby diagnosing other, treatable causes of menstrual irregularities. A retrospective chart review of 178 girls presenting to an inner-city hospital-based adolescent clinic within three years of menarche was performed. Personal and family medical and menarcheal history was assessed, and findings on physical and laboratory examination performed were evaluated. Of the 178 girls still perimenarcheal at presentation, 47 were the focus of this study. Of these, 39 had no significant findings on physical examination, while 3 had signs of functional ovarian hyperandrogenism (FOH) including obesity, hirsutism, and moderate acne with corresponding LH/FSH ratios>3, although pelvic ultrasound examination revealed normal ovaries. Four of the 39 patients with normal physical exams had LH/FSH testing done, and 1 of the 4 had an abnormal LH/FSH ratio, indicating possible FOH. Two of the 47 patients were pregnant. Other laboratory abnormalities included microcytic, hypochromic anemia in patients, and an elevated Erythrocyte Sedimentation Rate in a patient later diagnosed with a rheumatologic disorder. Those perimenarcheal girls presenting with irregular menses and findings including obesity, acne, or pallor, were likely to have treatable causes of menstrual irregularities. In one of the four girls with a normal physical examination, hormonal testing indicated possible FOH, thus suggesting that hormonal evaluation of perimenarcheal girls with menstrual irregularities may be justified, as it may reveal previously unsuspected pathology.

    2013-10-01

    The LiveWall concept envisioned as an outgrowth of the Precision Information Environment (PIE) project allows communications between separate groups using interactive video, audio, and a shared desktop environment; this allows everyone to participate and collaborate in real time, regardless of location. The LiveWall concept provides a virtual window to other locations, where all parties can interact and collaboratively work with each other. This functionality is intended to improve multi-site coordination amongst emergency operations centers (EOC), field operations sites and across organizations and jurisdictions to accommodate communications during routine and emergency events. For the initial LiveWall operational evaluation PNNL partnered with the Seattle Police Department (SPD). This partnership allowed for the creation of an excellent LiveWall test bed specific to law enforcement. This partnership made it possible to test the LiveWall concept with scenarios involving the many facets of the law enforcement work done by SPD. PNNL and SPD agreed that integrating the systems into operations for a real event would be the best test of the technology and give SPD staff greater visibility into the functionality and benefits offered by the LiveWall concept.

    Prior to the acquisition of land by the U.S. Department of War in February 1943 and the creation of the Hanford Site, the land along the Columbia River was home to over 1000 people. Farming and orchard operations by both homesteaders and commercial organizations were prevalent. Orchard activities and the associated application of lead arsenate pesticide ceased in 1943, when residents were moved from the Hanford Site at the beginning of the Manhattan Project. Today, the residues from historical application of lead arsenate pesticide persist in some locations on the Hanford Site. In 2012, the U.S. Department of Energy, U.S. Environmental Protection Agency, and Washington State Department of Ecology established the 100-OL-1 Operable Unit (OU) through the Hanford Federal Facility Agreement and Consent Order, known as the Tri-Party Agreement. The pre-Hanford orchard lands identified as the 100-OL-1 OU are located south of the Columbia River and east of the present-day Vernita Bridge, and extend southeast to the former Hanford townsite. The discontinuous orchard lands within 100-OL-1 OU are approximately 20 km2 (5000 ac). A pilot study was conducted to support the approval of the remedial investigation/feasibility study work plan to evaluate the 100-OL-1 OU. This pilot study evaluated the use of a field portable X-ray fluorescence (XRF) analyzer for evaluating lead and arsenic concentrations on the soil surface as an indicator of lead arsenate pesticide residues in the OU. The objectives of the pilot study included evaluating a field portable XRF analyzer as the analytical method for decision making, estimating the nature and extent of lead and arsenic in surface soils in four decision units, evaluating the results for the purpose of optimizing the sampling approach implemented in the remedial investigation, and collecting information to improve the cost estimate and planning the cultural resources review for sampling activities in the remedial investigation.

    OBJECTIVES: The objectives of the pilot study were to modify existing psychological first aid (PFA) materials so they would be appropriate for use with institutionalized elders, evaluate the feasibility of using nursing home staff to deliver the intervention to residents, and solicit feedback from residents about the intervention. The STORM Study, an acronym for "services for treating older residents' mental health", is the first step in the development of an evidence-based disaster mental health intervention for this vulnerable and underserved population. METHOD: Demographic characteristics were collected on participating residents and staff. Program evaluation forms were completed by staff participants during the pilot test and nurse training session. Staff and resident discussion groups were conducted during the pilot test to collect qualitative data on the use of PFA in nursing homes. RESULTS: Results demonstrate the feasibility of the PFA program to train staff to provide residents with PFA during disasters. CONCLUSIONS: Future research should focus on whether PFA improves coping and reduces stress in disaster exposed nursing home residents.

    The NASA Ames Research Center developed an oblique-wing research plane from NASA's digital fly-by-wire airplane. Oblique-wing airplanes show large cross-coupling in control and dynamic behavior which is not present on conventional symmetric airplanes and must be compensated for to obtain acceptable handling qualities. The large vertical motion simulator at NASA Ames-Moffett was used in the piloted evaluation of a proposed flight control system designed to provide decoupled handling qualities. Five discrete flight conditions were evaluated ranging from low altitude subsonic Mach numbers to moderate altitude supersonic Mach numbers. The flight control system was effective in generally decoupling the airplane. However, all participating pilots objected to the high levels of lateral acceleration encountered in pitch maneuvers. In addition, the pilots were more critical of left turns (in the direction of the trailing wingtip when skewed) than they were of right turns due to the tendency to be rolled into the left turns and out of the right turns. Asymmetric side force as a function of angle of attack was the primary cause of lateral acceleration in pitch. Along with the lateral acceleration in pitch, variation of rolling and yawing moments as functions of angle of attack caused the tendency to roll into left turns and out of right turns.

    To evaluate the process and the results of the pilot phase of the Parenting skills development programme for families (PSP), an evidence-based strategy to promote positive parenting skills in socio-educational and community settings. Before-after quasi-experimental design without a control group for the evaluation of the pilot phase of the PSD carried out in Barcelona (Spain) between October 2011 and June 2013. Eleven groups were established with the participation of 128 parents and 28 professionals. The intervention consisted of 10 or 11 sessions. Information was collected through questionnaires for parents and in-depth individual or group interviews for professionals. Parenting skills were identified through a questionnaire with six dimensions. The situation before the intervention (T0) and immediately after (T1) was compared. In T1 the number of participants decreased to 83 (retention=64.8%). Participants showed a high level of satisfaction with different dimensions of the program. On a maximum score of 10, the satisfaction of professionals was 8.7. Several key aspects and areas for improvement were identified for the future of the intervention. The quantitative analysis revealed improvements in all parenting skills dimensions and these improvements were consistent with the results of the qualitative analysis. The results of the pilot phase of this program suggest that a universal intervention on parenting skills can improve wellbeing among parents. Copyright © 2015 SESPAS. Published by Elsevier Espana.

    Those bereaved by suicide are at increased risk of psychological harm, which can be reduced with the provision of timely support. This paper outlines an evaluation of a pilot police-led suicide strategy, in comparison to a coroner-led suicide strategy looking at the number, and length of time it takes for deaths to be recorded for each strategy. Additionally, the police-led strategy offers timely contact from support services for bereaved individuals. We examined what impact this offer of support had on the capacity of support services. A mixed methods evaluation compared how long it took for suspected suicides to be recorded using both strategies. The number of referrals received by support services during the pilot strategy were compared with those from previous years. A feedback focus group, and interviews, were held with key stakeholders. The coroner strategy was more consistent at identifying suspected suicides; however, reports were filed quicker by the police. Bereaved individuals were willing to share contact details with police officers and consent for referral to support services which lead to increased referrals. The focus group and interviews revealed that the pilot police strategy needs better integration into routine police practice. This strategy has the potential to deliver a real benefit to those bereaved by suicide; however, there are still aspects which could be improved. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    In recent studies, it has been observed that loss of control in flight is the most frequent primary cause of accidents. A significant share of accidents in this category can be remedied by upset prevention if possible, and by upset recovery if necessary, in this order of priorities. One of the most important upsets to be recovered from is stall. Recent accidents have shown that a correct stall recovery maneuver remains a big challenge in civil aviation, partly due to a lack of pilot training. A possible strategy to support the flight crew in this demanding context is calculating a recovery guidance signal, and showing this signal in an intuitive way on one of the cockpit displays, for example by means of the flight director. Different methods for calculating the recovery signal, one based on fast model predictive control and another using an energy based approach, have been evaluated in four relevant operational scenarios by experienced commercial as well as test pilots in the Vertical Motion Simulator at NASA Ames Research Center. Evaluation results show that this approach could be able to assist the pilots in executing a correct stall recovery maneuver.

    Nurse educators are charged to develop and evaluate curricula on systems thinking to prepare future nurses to provide safe nursing care. The goal of this pilot study was to design and evaluate a four-hour educational strategy that prepares future professional nurses to use systems thinking approaches in the delivery of safe patient care. This study exposed prelicensure baccalaureate nursing students to systems thinking principles, which included didactic and experiential activities. A descriptive design was used to determine the effect of an on-campus educational strategy. A paired samples t-test revealed statistical significance from pretest to posttest.

    Health professional schools are responsible for producing graduates with competencies and attitudes to address health inequities and respond to priority health needs. Health professional schools striving towards social accountability founded the Training for Health Equity Network (THEnet). This article describes the development of THEnet evaluation framework for socially accountable health professional education, presents the framework to be used as a tool by other schools and discusses the findings of pilot implementation at five schools. The framework was designed collaboratively and built on Boelen and Woollard's conceptualization, production and usability model. It includes key components, linked to aspirational statements, indicators and suggested measurement tools. Five schools completed pilot implementation, involving workshops, document/data review and focus group discussions with faculty, students and community members. Three sections of the framework consider: How does our school work?; What do we do? and What difference do we make? Pilot testing proved that the evaluation framework was acceptable and feasible across contexts and produced findings useful at school level and to compare schools. The framework is designed as a formative exercise to help schools take a critical look at their performance and progress towards social accountability. Initiatives to implement the framework more widely are underway. The framework effectively aids in identifying strengths, weaknesses and gaps, with a view to schools striving for continuous self-improvement. THEnet evaluation framework is applicable and useful across contexts. It is possible and desirable to assess progress towards social accountability in health professional schools and this is an important step in producing health professionals with knowledge, attitudes, and skills to meet the challenges of priority health needs of underserved populations.

    NextGen operations are associated with a variety of changes to the national airspace system (NAS) including changes to the allocation of roles and responsibilities among operators and automation, the use of new technologies and automation, additional information presented on the flight deck, and the entire concept of operations (ConOps). In the transition to NextGen airspace, aviation and air operations designers need to consider the implications of design or system changes on human performance and the potential for error. To ensure continued safety of the NAS, it will be necessary for researchers to evaluate design concepts and potential NextGen scenarios well before implementation. One approach for such evaluations is through human performance modeling. Human performance models (HPMs) provide effective tools for predicting and evaluating operator performance in systems. HPMs offer significant advantages over empirical, human-in-the-loop testing in that (1) they allow detailed analyses of systems that have not yet been built, (2) they offer great flexibility for extensive data collection, (3) they do not require experimental participants, and thus can offer cost and time savings. HPMs differ in their ability to predict performance and safety with NextGen procedures, equipment and ConOps. Models also vary in terms of how they approach human performance (e.g., some focus on cognitive processing, others focus on discrete tasks performed by a human, while others consider perceptual processes), and in terms of their associated validation efforts. The objectives of this research effort were to support the Federal Aviation Administration (FAA) in identifying HPMs that are appropriate for predicting pilot performance in NextGen operations, to provide guidance on how to evaluate the quality of different models, and to identify gaps in pilot performance modeling research, that could guide future research opportunities. This research effort is intended to help the FAA

    This paper analyses the food waste collection and transportation (C&T) system in a pilot project in Suzhou by using a novel performance evaluation method. The method employed to conduct this analysis involves a unified performance evaluation index containing qualitative and quantitative indicators applied to data from Suzhou City. Two major inefficiencies were identified: a) low system efficiency due to insufficient processing capacity of commercial food waste facilities; and b) low waste resource utilization due to low efficiency of manual sorting. The performance evaluation indicated that the pilot project collection system's strong points included strong economics, low environmental impact and low social impact. This study also shows that Suzhou's integrated system has developed a comprehensive body of laws and clarified regulatory responsibilities for each of the various government departments to solve the problems of commercial food waste management. Based on Suzhou's experience, perspectives and lessons can be drawn for other cities and areas where food waste management systems are in the planning stage, or are encountering operational problems.

    Educational methods for residents are shifting toward greater learner independence aided by technological advances. A Web-based program using a podcast was created for resident EEG instruction, replacing conventional didactics. The EEG curriculum also consisted of EEG interpretations under the tutelage of a neurophysiologist. This pilot study aimed to objectively evaluate the effectiveness of the podcast as a new teaching tool. A podcast for resident EEG instruction was implemented on the Web, replacing the traditional lecture. After Institutional Review Board approval, consent was obtained from the participating residents. Using 25-question evaluation tools, participants were assessed at baseline before any EEG instruction, and reassessed after podcasting and after 10 clinical EEG exposures. Each 25-item evaluation tool contained tracings used for clinical EEG interpretations. Scores after podcast training were also compared to scores after traditional didactic training from a previous study among anesthesiology trainees. Ten anesthesiology residents completed the study. The mean scores with standard deviations are 9.50 ± 2.92 at baseline, 13.40 ± 3.31 (p = 0.034) after the podcast, and 16.20 ± 1.87 (p = 0.019) after interpreting 10 EEGs. No differences were noted between the mean educational tool scores for those who underwent podcasting training compared to those who had undergone traditional didactic training. In this pilot study, podcast training was as effective as the prior conventional lecture in meeting the curricular goals of increasing EEG knowledge after 10 EEG interpretations as measured by assessment tools.

    During the flight trials known as Gulfstream-V Synthetic Vision Systems Integrated Technology Evaluation (GV-SITE), a Speech Recognition System (SRS) was used by the evaluation pilots. The SRS system was intended to be an intuitive interface for display control (rather than knobs, buttons, etc.). This paper describes the performance of the current "state of the art" Speech Recognition System (SRS). The commercially available technology was evaluated as an application for possible inclusion in commercial aircraft flight decks as a crew-to-vehicle interface. Specifically, the technology is to be used as an interface from aircrew to the onboard displays, controls, and flight management tasks. A flight test of a SRS as well as a laboratory test was conducted.

    Parental incarceration can be devastating for families. Children may experience difficulties, and the stress on caregivers who take on unexpected childrearing is high. We implemented and evaluated a family-level intervention with caregivers and children experiencing parental (typically maternal) incarceration, in a community setting. We partnered with a community-based organization serving families with an incarcerated parent to conduct a pilot trial of the Strengthening Families Program (SFP). Process evaluation indicated high implementation fidelity, satisfaction, engagement, and attendance. Outcome evaluation results indicated positive changes in family-level functioning, caregivers' positive parenting, and caregiver depression symptoms from pre- to post-intervention, with some changes retained at follow-up 4 months later. Implications for preventive interventions with children of incarcerated parents, and their caregivers, are discussed.

    Globally, injury is the fourth major cause of death and the third leading contributor to Disability Adjusted Life Years lost due to health conditions, with the greatest burden borne by low-middle income countries (LMICs) where injury data is scarce. In the absence of effective vital registration systems, mortuaries have been shown to provide an alternative source of cause of death information for practitioners and policy makers to establish strategic injury prevention policies and programs. This evaluation sought to assess the feasibility of implementing a standardised fatal injury data collection process to systematically collect relevant fatal injury data from mortuaries. The process evaluation is described. A manual including a one page data collection form, coding guide, data dictionary, data entry and analysis program was developed through World Health Organization and Monash University Australia collaboration, with technical advice from an International Advisory Group. The data collection component was piloted in multiple mortuaries, in five LMICs (Egypt, India, Sri-Lanka, Tanzania and Zambia). Process evaluation was based on a questionnaire completed by each country's Principal Investigator. Questionnaires were completed for data collections in urban and rural mortuaries between September 2010 and February 2011. Of the 1795 reported fatal injury cases registered in the participating mortuaries, road traffic injury accounted for the highest proportion of cases, ranging from 22% to 87%. Other causes included burns, poisoning, drowning and falls. Positive system attributes were feasibility, acceptability, usefulness, timeliness, and simplicity and data field completeness. Some limitations included short duration of the pilot studies, limited injury data collector training and apparent underreporting of cases to the medico-legal system or mortuaries. The mortuary has been shown to be a potential data source for identifying injury deaths and their circumstances

    In October 1998, the National Library of Medicine (NLM) launched a pilot project to learn about the role of public libraries in providing health information to the public and to generate information that would assist NLM and the National Network of Libraries of Medicine (NN/LM) in learning how best to work with public libraries in the future. Three regional medical libraries (RMLs), eight resource libraries, and forty-one public libraries or library systems from nine states and the District of Columbia were selected for participation. The pilot project included an evaluation component that was carried out in parallel with project implementation. The evaluation ran through September 1999. The results of the evaluation indicated that participating public librarians were enthusiastic about the training and information materials provided as part of the project and that many public libraries used the materials and conducted their own outreach to local communities and groups. Most libraries applied the modest funds to purchase additional Internet-accessible computers and/or upgrade their health-reference materials. However, few of the participating public libraries had health information centers (although health information was perceived as a top-ten or top-five topic of interest to patrons). Also, the project generated only minimal usage of NLM's consumer health database, known as MEDLINEplus, from the premises of the monitored libraries (patron usage from home or office locations was not tracked). The evaluation results suggested a balanced follow-up by NLM and the NN/LM, with a few carefully selected national activities, complemented by a package of targeted activities that, as of January 2000, are being planned, developed, or implemented. The results also highlighted the importance of building an evaluation component into projects like this one from the outset, to assure that objectives were met and that evaluative information was available on a timely basis, as was

  13. A pilot study to evaluate effectiveness of botulinum toxin in treatment of androgenetic alopecia in males

    Full Text Available Introduction: Androgenetic alopecia is a common form of alopecia with multifactorial etiology. Finasteride and minoxidil are approved by the FDA for the treatment of androgenetic alopecia. Balding scalp is believed to have relative microvascular insufficiency. Blood vessels in the scalp travel through the intramuscular plane. Intramuscular injection of botulinum toxin relaxes muscles and thereby increases blood flow in balding scalp. We conducted a pilot study to evaluate the efficacy of botulinum toxin in androgenetic alopecia management. Material and Methods: The study was conducted in a tertiary care center. A total of 10 male patients with androgenetic alopecia meeting inclusion criteria of the study were included. In the scalp, 30 sites were injected with 5 U of botulinum toxin in each site. Preprocedure photograph taken and evaluation was done, which was repeated after 24 weeks. Efficacy was assessed by photography and self-assessment scoring was done by patients. Results: Of 10 patients, 8 had good to excellent response on photographic assessment. At the end of 24 weeks, 1 patient showed poor and 1 showed fair response to treatment. As per self-assessment, 7of 10 patients showed good to excellent response. Two patients had fair response and 1 patient showed poor response to treatment. Conclusion: Botulinum toxin was found to be safe and effective therapy for the management of androgenetic alopecia in this pilot study. Studies with larger sample size and randomized controlled trials are required to establish the role of botulinum toxin in the management of androgenetic alopecia.

    Evaluating quality of health care is increasingly recognized as an important contributor to the advancement of health-care delivery. We recently developed a set of quality indicators for headache care, intended to be applicable across countries, cultures and settings so that deficiencies in headache care worldwide might be recognized and rectified. These indicators themselves require evaluation and proof of fitness for purpose. This pilot study begins this process. We tested the quality indicators in the tertiary headache centres of the University of Duisburg-Essen in Essen, Germany, and the Hospital da Luz in Lisbon, Portugal. Using seven previously-developed enquiry instruments, we interrogated health-care providers (HCPs), including doctors, nurses, psychologists and physiotherapists, as well as consecutive patients and their medical records. The questionnaires were easily understood by both HCPs and patients and were not unduly time-consuming. The results from the two headache centres were comparable despite their differences in structure, staffing and language. These findings met the purpose of the study. Diagnoses were made according to ICHD criteria and critically evaluated during follow-up. However, diagnostic diaries and instruments assessing burden and response to treatment were not always in place or routinely utilised. Triage systems adjusted waiting times to urgency of need. Treatment plans included pathways to other specialities. Patients felt welcomed, reassured and educated, and were mostly satisfied. Discussion points arose over inclusion of psychological therapies in treatment plans; over recording of outcomes; over indicators of efficiency and equitability (protocols to limit wastage of resources, systems to measure input costs and means of ensuring equal access to the services); and over protocols for reporting serious adverse events. This pilot study to assess feasibility of the methods and acceptability of the instruments of headache service

    This paper describes the implementation and evaluation of a yaw rate to throttle feedback system designed to replace a damaged rudder. It can act as a Dutch roll damper and as a means to facilitate pilot input for crosswind landings. Enhanced propulsion control modes were implemented to increase responsiveness and thrust level of the engine, which impact flight dynamics and performance. Piloted evaluations were performed to determine the capability of the engines to substitute for the rudder function under emergency conditions. The results showed that this type of implementation is beneficial, but the engines' capability to replace the rudder is limited.

  20. Results from evaluation of a long pulse pilot data acquisition system on MAST

    International Nuclear Information System (INIS)

    McArdle, G.J.; Milne, P.G.

    2006-01-01

    The limited memory and data rate of CAMAC data acquisition systems is unable to accommodate proposed increases in the MAST plasma duration of up to an order of magnitude. Therefore, some recent pilot exercises have evaluated new technology to replace CAMAC. One of the pilot systems explored the use of modern CompactPCI 'intelligent' data acquisition devices. These can operate stand-alone, using an onboard Linux operating system and Ethernet connection without the need for a host computer. The approach to data capture and management was simplified to minimise development time. A simple Linux shell script running on each device was found sufficient to automate the whole acquisition cycle, and this was successfully commissioned in one day. This approach avoided the need for compiled programs but prevented use of the in-house standard shot file archiving library. Instead, each channel's data was written to a separate file as a simple array of samples. This work around was found to offer advantages in terms of flexibility, simplicity and scalability. The experience of handling much higher volumes of acquired data than was practicable with CAMAC has also raised important issues about the scalability of existing data management and analysis systems when each data item contains many mega-samples. The experience and lessons learned will help guide the future direction of data acquisition strategy on MAST

  1. Piloted "Well Clear" Performance Evaluation of Detect-and-Avoid Systems with Suggestive Guidance

    Mueller, Eric R.; Santiago, Confesor; Watza, Spencer

    2016-01-01

    This study evaluated the performance of four prototype unmanned aircraft detect-and-avoid (DAA) display configurations, each with different informational elements driven by alerting and guidance algorithms. Sixteen unmanned aircraft pilots flew each combination of the display configurations, with half being given zero DAA surveillance sensor uncertainty and the other half experiencing errors that were comparable, and in some cases slightly better than, errors that were measured in DAA system flight tests. The displays that showed intruder alert information in altitude and heading bands had significantly fewer losses of well clear compared with alternative displays that lacked that information. This difference was significant from a statistical and practical perspective: those losses that did occur lasted for shorter periods and did not penetrate as far into the geometric "separation cylinder" as those in the non-banded displays. A modest level of DAA surveillance sensor uncertainty did not affect the proportion of losses of well clear or their severity. It is recommended that DAA traffic displays implement a band-type display in order to improve the safety of UAS operations in the National Airspace System. Finally, this report provides pilot response time distributions for responding to DAA alerts.

    We present the design, implementation, and evaluation of a subsidy program to introduce cleaner and more efficient household wood combustion technologies. The program was conducted in the city of Temuco, one of the most polluted cities in southern Chile, as a pilot study to design a new national stove replacement initiative for pollution control. In this city, around 90% of the total emissions of suspended particulate matter is caused by households burning wood. We created a simulated market in which households could choose among different combustion technologies with an assigned subsidy. The subsidy was a relevant factor in the decision to participate, and the inability to secure credit was a significant constraint for the participation of low-income households. Due to several practical difficulties and challenges associated with the implementation of large-scale programs that encourage technological innovation at the household level, it is strongly advisable to start with a small-scale pilot that can provide useful insights into the final design of a fuller, larger-scale program.

    The prevalence of tobacco smoking among Aboriginal and Torres Strait Islander people in Australia is comparatively high. To help combat this, an Aboriginal-specific social marketing campaign, 'Give up smokes for good', was piloted in South Australia in 2011. To evaluate the campaign, a face-to-face survey was conducted with two samples of convenience through Aboriginal Health services in South Australia (city and regional locations; n=190). Surveys assessed the cultural appropriateness of the campaign, campaign awareness and recognition, knowledge of the harms of smoking and smoking/quit smoking behaviours. Campaign awareness was high with 76.3% of participants aware of at least one aspect of the campaign. Participants indicated campaign materials (posters and radio ads) to be culturally appropriate. Knowledge that smoking and passive smoking caused illness was high (85.8% and 86.8%); however, knowledge of specific illnesses was not as high. Large proportions of participants had imposed bans on smoking in homes (73.2%) and in cars (75.9%). Our findings suggest the 'Give up smokes for good' campaign reached the intended audience with high levels of campaign awareness. Results also suggest the pilot campaign made progress in achieving its communication objectives. SO WHAT?: High quality, culturally targeted anti-tobacco poster and radio campaigns can be effective ways to reach Aboriginal Australians. Future research could explore the impact of this type of social marketing campaign, particularly in regards to the impact on quitting intention and behaviour.

    The purpose of this pilot study was to assess the impact of media literacy for tobacco prevention for youth delivered through a community site. A randomized pretest-posttest evaluation design with matched-contact treatment and control conditions. The pilot study was delivered through the YMCA in a lower-income suburban and rural area of Southwest Virginia, a region long tied, both economically and culturally, to the tobacco industry. Children ages 8 to 14 (76% white, 58% female) participated in the study (n = 38). The intervention was an antismoking media literacy program (five 1-hour lessons) compared with a matched-contact creative writing control program. General media literacy, three domains of tobacco-specific media literacy ("authors and audiences," "messages and meanings," and "representation and reality"), tobacco attitudes, and future expectations were assessed. Multiple regression modeling assessed the impact of the intervention, controlling for pretest measures, age, and sex. General media literacy and tobacco-specific "authors and audiences" media literacy improved significantly for treatment compared with control (p literacy measures and for tobacco attitudes were not significant. Future expectations of smoking increased significantly for treatment participants ages 10 and younger (p literacy are accompanied by an increase in future expectations to smoke for younger children.

    This study evaluated a pilot workshop for teaching communication skills to dental students. The methodology is based on an experiential learning approach, the use of realistic clinical scenarios, simulated patients, and an integrated teaching team of both educational researchers and dentists. Furthermore, the methodology was adapted for short workshops, which is thought to offer better possibilities for frequent and effective training of communication skills throughout the curriculum. The work-shop was piloted with groups of six to ten students from the sixth and tenth semesters (n=94). Results show that the majority of students found the tasks meaningful and well aligned with how they perceived their future profession as dentists. Most students also thought that they learned from the task. An interesting finding is that students not only found it instructive to practice how to communicate in authentic situations, but that they generally found the workshop to be thought-provoking while at the same time providing structure and intellectual tools for the future. A possible explanation for this finding is the sharing of explicit criteria for high-quality communication.

    Regulations to establish operational and performance requirements for unmanned aircraft systems (UAS) are being developed by a consortium of government, industry and academic institutions (RTCA, 2013). Those requirements will apply to the new detect-and-avoid (DAA) systems and other equipment necessary to integrate UAS with the United States (U.S) National Airspace System (NAS) and will be determined according to their contribution to the overall safety case. That safety case requires demonstration that DAA-equipped UAS collectively operating in the NAS meet an airspace safety threshold (AST). Several key gaps must be closed in order to link equipment requirements to an airspace safety case. Foremost among these is calculation of the systems risk ratio, the degree to which a particular system mitigates violation of an aircraft separation standard (FAA, 2013). The risk ratio of a DAA system, in combination with risk ratios of other collision mitigation mechanisms, will determine the overall safety of the airspace measured in terms of the number of collisions per flight hour. It is not known what the effectiveness is of a pilot-in-the-loop DAA system or even what parameters of the DAA system most improve the pilots ability to maintain separation. The relationship between the DAA system design and the overall effectiveness of the DAA system that includes the pilot, expressed as a risk ratio, must be determined before DAA operational and performance requirements can be finalized. Much research has been devoted to integrating UAS into non-segregated airspace (Dalamagkidis, 2009, Ostwald, 2007, Gillian, 2012, Hesselink, 2011, Santiago, 2015, Rorie 2015 and 2016). Several traffic displays intended for use as part of a DAA system have gone through human-in-the-loop simulation and flight-testing. Most of these evaluations were part of development programs to produce a deployable system, so it is unclear how to generalize particular aspects of those designs to general

    Flight research has shown the effectiveness of adaptive flight controls for improving aircraft safety and performance in the presence of uncertainties. The National Aeronautics and Space Administration's (NASA)'s Integrated Resilient Aircraft Control (IRAC) project designed and conducted a series of flight experiments to study the impact of variations in adaptive controller design complexity on performance and handling qualities. A novel complexity metric was devised to compare the degrees of simplicity achieved in three variations of a model reference adaptive controller (MRAC) for NASA's F-18 (McDonnell Douglas, now The Boeing Company, Chicago, Illinois) Full-Scale Advanced Systems Testbed (Gen-2A) aircraft. The complexity measures of these controllers are also compared to that of an earlier MRAC design for NASA's Intelligent Flight Control System (IFCS) project and flown on a highly modified F-15 aircraft (McDonnell Douglas, now The Boeing Company, Chicago, Illinois). Pilot comments during the IRAC research flights pointed to the importance of workload on handling qualities ratings for failure and damage scenarios. Modifications to existing pilot aggressiveness and duty cycle metrics are presented and applied to the IRAC controllers. Finally, while adaptive controllers may alleviate the effects of failures or damage on an aircraft's handling qualities, they also have the potential to introduce annoying changes to the flight dynamics or to the operation of aircraft systems. A nuisance rating scale is presented for the categorization of nuisance side-effects of adaptive controllers.

    The objective of this pilot study was to evaluate the effectiveness of a group-based intervention aiming at improving social and communication skills in individuals with autism spectrum disorder. Over a period of 11 months, N = 17 children and adolescents received treatment according to the manualised Frankfurt Social Skills Training (KONTAKT). Parent, teacher, expert and blind expert ratings were assessed to judge outcome regarding peer interaction, autistic behaviours, adaptive functioning and family burden. The participants exhibited improvements pre to follow-up treatment, particularly in the area of autistic symptomatology. Effect sizes (partial eta squared) ranged from 0.02 to 0.69. Among other things, regression models showed a positive influence of IQ and language skills on gains in social skills. Findings indicate that KONTAKT might be useful for enhancing social skills and reducing autism-related psychopathology over time in different contexts. Nevertheless, controlled trials are needed to reassure its effectiveness.

    Full Text Available The evaluation of the effects of transport collision often takes the form of ground reconnaissance. Undoubtedly, remotely piloted aircraft systems (RPAS can support and help the police, firefighters, security agents and paramedics in the event of a transport collision. Although there is a scarce amount of literature concerning the use of RPAS in crisis management, it is important to pay more attention to the benefits of this technology. The article describes the danger of collisions, as well as discusses the possibility of using RPAS, their functionality and potential utility. Sensors installed on RPAS can rapidly identify the place of the accident, the number of casualties, the type of damaged vehicles or the type of contamination.

    Full Text Available This article describes the pilot evaluation of two Positive Youth Development (PYD programs for youth with child onset chronic illness (COCI, reporting how the programs influenced participants’ character development. College students with COCI led high school students with COCI through activities pertaining to different aspects of growing up with a chronic illness. Participants completed the Positive Youth Development Inventory-Short Form (PYDI-S, which measures seven domains of youth perceptions of the contribution to their development from the program. Participants reported that both programs helped them the most with personal standards, which corresponds well to character development on the full version of the Positive Youth Development Inventory (PYDI. They also had high scores on prosocial behavior and future orientation, both important domains for character development. We discuss the idea that interventions promoting character development for youth with COCI are critical for promoting a positive narrative for chronically-ill youth, their parents, and society.

    National guidelines in the United Kingdom recommend training Clinical Nurse Specialists in psychological skills to improve the assessment and intervention with psychological problems experienced by people with a cancer diagnosis (National Institute for Health and Clinical Excellence, 2004). This pilot study evaluated a three-day training program combined with supervision sessions from Clinical Psychologists that focused on developing skills in psychological assessment and intervention for common problems experienced by people with cancer. Questionnaires were developed to measure participants' levels of confidence in 15 competencies of psychological skills. Participants completed these prior to the program and on completion of the program. Summative evaluation was undertaken and results were compared. In addition, a focus group interview provided qualitative data of participants' experiences of the structure, process, and outcomes of the program. Following the program, participants rated their confidence in psychological assessment and skills associated with providing psychological support as having increased in all areas. This included improved knowledge of psychological theories, skills in assessment and intervention and accessing and using supervision appropriately. The largest increase was in providing psycho-education to support the coping strategies of patients and carers. Thematic analysis of interview data identified two main themes including learning experiences and program enhancements. The significance of the clinical supervision sessions as key learning opportunities, achieved through the development of a community of practice, emerged. Although this pilot study has limitations, the results suggest that a combined teaching and supervision program is effective in improving Clinical Nurse Specialists' confidence level in specific psychological skills. Participants' experiences highlighted suggestions for refinement and development of the program

    Adolescent substance use rates in rural areas of the United States, such as upstate New York, have risen substantially in recent years, calling for new intervention approaches in response to this trend. The Mentor Foundation USA conducts the Living the Example (LTE) campaign to engage youth in prevention using an experiential approach. As part of LTE, youth create their own prevention messages following a training curriculum in techniques for effective messaging and then share them via social media. This paper reports on a pilot evaluation of the LTE program. To conduct a pilot test of LTE in two rural high schools in upstate New York. We hypothesized that positive antidrug brand representations could be promoted using social media strategies to complement the Shattering the Myths (STM) in-person, event-based approach (hypothesis 1, H1), and that youth would respond positively and engage with prevention messages disseminated by their peers. We also hypothesized that exposure to the social media prevention messages would be associated with more positive substance use avoidance attitudes and beliefs, reductions in future use intentions, and decreased substance use at posttest (hypothesis 2, H2). We adapted a previously published curriculum created by the authors that focuses on branding, messaging, and social media for prevention. The curriculum consisted of five, one-hour sessions. It was delivered to participating youth in five sequential weeks after school at the two high schools in late October and early November 2016. We designed a pre- and posttest pilot implementation study to evaluate the effects of LTE on student uptake of the intervention and short-term substance use and related outcomes. Working at two high schools in upstate New York, we conducted a pilot feasibility evaluation of LTE with 9th-grade students (ie, freshmen) at these high schools. We administered a 125-item questionnaire online to capture data on media use; attitudes toward social media

    An experimental investigation was conducted to study the effectiveness of modern flight displays in general aviation cockpits for mitigating Low Visibility Loss of Control and the Controlled Flight Into Terrain accidents. A total of 18 General Aviation (GA) pilots with private pilot, single engine land rating, with no additional instrument training beyond private pilot license requirements, were recruited to evaluate three different display concepts in a fixed-based flight simulator at the NASA Langley Research Center's General Aviation Work Station. Evaluation pilots were asked to continue flight from Visual Meteorological Conditions (VMC) into Instrument Meteorological Conditions (IMC) while performing a series of 4 basic precision maneuvers. During the experiment, relevant pilot/vehicle performance variables, pilot control inputs and physiological data were recorded. Human factors questionnaires and interviews were administered after each scenario. Qualitative and quantitative data have been analyzed and the results are presented here. Pilot performance deviations from the established target values (errors) were computed and compared with the FAA Practical Test Standards. Results of the quantitative data indicate that evaluation pilots committed substantially fewer errors when using the Synthetic Vision Systems (SVS) displays than when they were using conventional instruments. Results of the qualitative data indicate that evaluation pilots perceived themselves to have a much higher level of situation awareness while using the SVS display concept.

    This paper describes the pilot evaluation of an Internet-based intervention, designed to teach counselors and problem gamblers about how electronic gambling machines (EGMs) work. This study evaluated the tutorial using assessment tools, such as rating scales and test of knowledge about EGMs and random chance. The study results are based on a number of samples, including problem gambling counselors ( n  = 25) and problem gamblers ( n  = 26). The interactive tutorial was positively rated by both clients and counselors. In addition, we found a significant improvement in scores on a content test about EGM games for both clients and counselors. An analysis of the specific items suggests that the effects of the tutorial were mainly on those items that were most directly related to the content of the tutorial and did not always generalize to other items. This tutorial is available for use with clients and for education counselors. The data also suggest that the tutorial is equally effective in group settings and in individual settings. These results are promising and illustrate that the tool can be used to teach counselors and clients about game design. Furthermore, research is needed to evaluate its impact on gambling behavior.

    An interpretation report, generated with an electronic viewbox, is affected by two factors: image quality, which encompasses what can be seen on the display, and computer human interaction (CHI), which accounts for the cognitive load effect of locating, moving, and manipulating images with the workstation controls. While a number of subject experiments have considered image quality, only recently has the affect of CHI on total interpretation quality been measured. This paper presents the results of a pilot study conducted to evaluate the total interpretation quality of the FilmPlane2.2 radiology workstation for patient folders containing single forty-slice CT studies. First, radiologists interpreted cases and dictated reports using FilmPlane2.2. Requisition forms were provided. Film interpretation was provided by the original clinical report and interpretation forms generated from a previous experiment. Second, an evaluator developed a list of findings for each case based on those listed in all the reports for each case and then evaluated each report for its response on each finding. Third, the reports were compared to determine how well they agreed with one another. Interpretation speed and observation data was also gathered.

    To pilot test the Birth Unit Design Spatial Evaluation Tool (BUDSET) in an Australian maternity care setting to determine whether such an instrument can measure the optimality of different birth settings. Optimally designed spaces to give birth are likely to influence a woman's ability to experience physiologically normal labor and birth. This is important in the current industrialized environment, where increased caesarean section rates are causing concerns. The measurement of an optimal birth space is currently impossible, because there are limited tools available. A quantitative study was undertaken to pilot test the discriminant ability of the BUDSET in eight maternity units in New South Wales, Australia. Five auditors trained in the use of the BUDSET assessed the birth units using the BUDSET, which is based on 18 design principles and is divided into four domains (Fear Cascade, Facility, Aesthetics, and Support) with three to eight assessable items in each. Data were independently collected in eight birth units. Values for each of the domains were aggregated to provide an overall Optimality Score for each birth unit. A range of Optimality Scores was derived for each of the birth units (from 51 to 77 out of a possible 100 points). The BUDSET identified units with low-scoring domains. Essentially these were older units and conventional labor ward settings. The BUDSET provides a way to assess the optimality of birth units and determine which domain areas may need improvement. There is potential for improvements to existing birth spaces, and considerable improvement can be made with simple low-cost modifications. Further research is needed to validate the tool.

    Fatigue is a common symptom that lowers the quality of life of patients with cancer, affecting between 60% and 90% of patients. Relatively few options are available for the treatment of this debilitating condition. Modafinal, a psychostimulant developed for the treatment of narcolepsy, has been used to treat fatigue in other diseases such as multiple sclerosis, but little data support its use in cancer patients. The primary objective of this open-label pilot study was to evaluate the safety, and efficacy of modafinil in improving cancer-related fatigue (CRF) as measured by the Brief Fatigue Inventory (BFI). The effect of this agent on depression, quality of life, functional status, and cognitive function was also assessed. Modafinal was self-administered at a dose of 100 mg/d during weeks 1-2, and 200 mg during weeks 3-4. Assessments were performed at baseline, 2, and 4 weeks. BFI score was improved in 46% of patients at 2 weeks and 75% at 4 weeks (p = 0.025). Hospital Anxiety and Depression Scale scores declined at 2 and 4 weeks (p < 0.001). Most scales for neurocognitive function were unchanged. Score for all Functional Assessment of Cancer Therapy-Brain (FACT-BR) subscales (measuring quality of life), except social/family well-being, were improved (p < 0.05) at 2 and 4 weeks. Significant changes in Eastern Cooperative Oncology Group (ECOG) performance status were noted, with 40% of patients improving at least one level. Modafinil was well-tolerated with only one patient discontinuing treatment due to drug-related toxicity. In this pilot study modafinil was well-tolerated and effective for fatigue in patients with cancer. Improvements were also seen in mood, quality of life, and functional status.

    It has been proven that ultrasonic pretreatment (UP) has positive effect on biogas generation from previous lab-scale studies. However, that is not always the case in larger scale processes. The purpose of this study was to evaluate the effectiveness of UP to biogas generation in terms of anaerobic digestion process and energy efficiency. Parameters including total solids (TS) and ultrasonic treatment operational parameters of organic solid waste (OSW) resulted from our past lab scale UP studies were applied in this study. OSW with 6-10% TS was treated using a lab-scale ultrasonic processor using various power densities (0.2-0.6 W/mL) at different time periods up to 30 min. Results of lab scale confirmed that OSW with 6% TS sonicated with 0.2 W/mL power density in 30 min gave the best outcome for the pilot scale experiment. To simulate the condition of an actual scale, in addition to energy analysis, two different organic loading rates (OLR), namely 500 and 1500 gVS/m 3 day were examined. The pilot digester was fed with OSW with or without the pretreatment based on the aforementioned specifications. The results showed that UP effectively improves biogas generation in terms of quantity and quality (CH 4 /CO 2 ). Furthermore, it decreases the time to reach the maximum cumulative biogas volume comparing to the untreated feed. The key achievement of this research has confirmed that although the relative increase in the energy gain by the influence of UP was more remarkable under the 500 gVS/m 3 day OLR, energy analysis showed a better energy gain and energy benefit as well as jumping in biogas yield up to 80% for UP treated OSW under 1500 gVS/m 3 day OLR.

    Technology evaluation of integrated/digital OR is needed since very little literature has been published on the subject. The integrated OR is a technological solution intended for minimally invasive surgery where the surgeons have complete control of the environment, devices and image distribution. Before such an investment, Health Technology Assessment can be used as a method to evaluate what vendors' state, i.e. the fact that the integrated OR is a very effective and efficient solution. Then a follow-up evaluation could be useful after the installation to test the users' satisfaction and give suggestions to the community about real- experienced integrated OR advantage. A multiple answer questionnaire has been handed to 17 surgeons and 9 scrub nurses form Varese Town and University Hospital to evaluate the degree of satisfaction after 2 years of use of integrated ORs. Surgeons and scrub nurses agree that the integrated OR can be very effective in increasing quality, risk reduction and surgery time reduction through the use of digitalized video acquisition system, boom-mounted devices and multiple displays. Scrub nurses are a little bit more confident than surgeons that medical device control could reduce the confusion inside the OR and reduce the number of setting errors. A very positive judgment was given to the system's teaching capabilities, but both surgeons and scrub nurses agree that a great degree of education and a cultural change are needed to use the system in a correct and complete way. Results show that there is a deep appreciation of the system which proved to be efficient (reducing surgery time and enhancing surgical quality) and effective. This is a pilot study based on few collected data, but the questionnaire could be handed to many hospitals where integrated ORs are present, in order to achieve a significant degree of assessment and find common topics to be considered fundamental especially in the evaluating phase.

    While videoconferencing, telementoring, and peer support have been shown to enhance services in some instances, there has been no research investigating the use of these technologies in supporting professionals managing clients with dementia. The objective of this research was to evaluate expansion of an old age psychiatry consultation service and pilot test a model to improve medical supervision and clinical governance for staff within regional and remote areas using remote information technology. The design was a mixed methods (qualitative and quantitative) evaluation using before, mid-point and post-implementation semi-structured interviews and questionnaires to examine orientation, acceptance, and impact underpinned by theoretical approaches to evaluation. Education evaluations used a Likert style response template. Participants were 18 dementia service staff, including staff from linked services and old age psychiatrists. Qualitative interviews addressed the pilot implementation including: expectations, experiences, strategies for improving the pilot, and perceived impact on work practice and professional development opportunities. There was high satisfaction with the program. The case conference process contributed to perceived improved outcomes for clients, family, and staff. Clinicians perceived improvement in family carer and staff carer stress and their confidence in managing clients with behavioral and psychological symptoms of dementia (BPSD). Thematic analysis indicated that the pilot enhanced professional development, decreased travel time, and improved team cohesion. Given the increasing aging population in regional, rural, and remote areas, initiatives using videoconferencing and telementoring will help to develop a confident and skilled workforce. This pilot program was found to be acceptable and feasible. Potential benefits for clients and family carers should be examined in future resesarch.

    School connectedness is an important protective factor for adolescent risk-taking behaviour. This study examined a pilot version of the Skills for Preventing Injury in Youth (SPIY) programme, combining teacher professional development (PD) for increasing school connectedness (connectedness component) with a risk and injury prevention curriculum for early adolescents (curriculum component). A process evaluation was conducted on the connectedness component, involving assessments of programme reach, participant receptiveness and initial use, and a preliminary impact evaluation was conducted on the combined connectedness and curriculum programme. The connectedness component was well received by teacher participants, who saw benefits for both themselves and their students. Classroom observation also showed that teachers who received PD made use of the programme strategies. Grade 8 students who participated in the SPIY programme were less likely to report violent behaviour at 6-month follow-up than were control students, and trends also suggested reduced transport injuries. The results of this research support the use of the combined SPIY connectedness and curriculum components in a large-scale effectiveness trial to assess the impact of the programme on students' connectedness, risk-taking and associated injuries.

    This report describes the design and evaluation of an interprofessional pilot training course aimed at pre-licensure practitioners working with post-stroke patients in community-based settings. The course was developed by community-based practitioners from nine health professions. Course learning activities included traditional methods (lectures) and interactive modules (problem-based learning and exchange-based learning). The study's aim was to assess the program's effectiveness in adapting and incorporating knowledge, skills and self-confidence when delivering tertiary care in therapeutic pool environments; gauge adoption of course principles into practice, and assess overall course satisfaction. Methods of evaluation included conceptual mapping of course format, pre- and post-questionnaires, daily reflection questionnaires, course satisfaction survey and adoption survey, 10 weeks follow-up. Overall, the findings indicate students' knowledge, skills and self-confidence in delivering effective post-stroke care increased following the training. Students reported adopting clinical practices in 10 weeks follow-up. Implications for designing interprofessional curricula are discussed.

    Work-related stress among midwives results in secondary traumatic stress, posttraumatic stress disorder, and job attrition. The purpose of this pilot project was to evaluate the effectiveness of a holistic, web-based program using holistic modalities for stress reduction and improved coping among certified nurse-midwives. A convenience sample of 10 midwives participated in a web-based holistic stress reduction intervention using yoga, mindfulness-based stress reduction, and meditation for four days each week over 4 weeks. Participants completed pre- and postintervention questionnaires (Perceived Stress Scale [PSS] and the Coping Self-Efficacy Scale [CSES]) for evaluation of effectiveness. The PSS means showed improvement in midwives' stress (16.4-12.3). The CSES means showed improvement in coping (174.8-214.5). Improvement was shown in each subscale of the CSES ("uses problem-focused coping": 19.2%; "stops unpleasant thoughts and emotions": 20.3%; and "gets support from family and friends": 16.6%). Findings suggest the potential for stress reduction and improved coping skills after using holistic techniques in a web-based format within a cohort of nurse-midwives. Further research of web-based, holistic intervention for stress reduction among midwives is warranted.

    Full Text Available The solid flow in air-catalyst in circulating fluidized bed was simulated with CFD model to obtain axial and radial distribution. Therefore, project parameters were confirmed and steady state operation condition was improved. Solid holds up axial end radial profiles simulation and comparison with gamma transmission measurements are in a good agreement. The transmission signal from an 241Am radioactive source was evaluated in NaI(Tl detector coupled to multichannel analyzer. This non intrusive measuring set up is installed at riser of a cold pilot unit to determine parameters of FCC catalyst flow at several concentrations. Mass flow rate calculated by combining solid hold up and solid phase velocity measurements was compared with catalyst inlet measured at down-comer. Evaluation in each measured parameter shows that a relative combined uncertainty of 6% in a 95% interval was estimated. Uncertainty analysis took into account a significant correlation in scan riser transmission measurements. An Eulerian approach of CFD model incorporating the kinetic theory of granular flow was adopted to describe the gas–solid two-phase flows in a multizone circulating reactor. Instantaneous and local gas-particle velocity, void fraction and turbulent parameters were obtained and results are shown in 2 D and 3D graphics.

    Pilot-scale cooling towers can be used to evaluate corrosion, scaling, and biofouling control strategies when using particular cooling system makeup water and particular operating conditions. To study the potential for using a number of different impaired waters as makeup water, a pilot-scale system capable of generating 27,000 kJ∕h heat load and maintaining recirculating water flow with a Reynolds number of 1.92 × 10(4) was designed to study these critical processes under conditions that are similar to full-scale systems. The pilot-scale cooling tower was equipped with an automatic makeup water control system, automatic blowdown control system, semi-automatic biocide feeding system, and corrosion, scaling, and biofouling monitoring systems. Observed operational data revealed that the major operating parameters, including temperature change (6.6 °C), cycles of concentration (N = 4.6), water flow velocity (0.66 m∕s), and air mass velocity (3660 kg∕h m(2)), were controlled quite well for an extended period of time (up to 2 months). Overall, the performance of the pilot-scale cooling towers using treated municipal wastewater was shown to be suitable to study critical processes (corrosion, scaling, biofouling) and evaluate cooling water management strategies for makeup waters of complex quality.

    Purpose: To demonstrate that virtual lectures can substitute conventional lectures in radiology education for medical students. Methods and materials: During the course 2005–2006, 89 out from 191 (46.6%) third year students of a subject entitled “General Radiology”, participated voluntarily in a pilot study including 22 virtual lectures (Flash presentations translated from the same PowerPoint presentations of conventional lectures, adding recorded narration and navigation tools). Participants (P) studied by means of virtual lectures, while non-participants (NP) assisted to conventional lectures. The results of the final oral exam classified from 0 to 3, and a 60-questions evaluation on image interpretation were used to compare both groups after training. Finally, 34 students from the group P (38.2%) fulfilled a 10-points scale quality survey about the project. Results: Final exam qualifications were significantly higher for P than for NP (2.11 ± 0.85 versus 1.73 ± 1.04) as well as the number of correct answers of the evaluation on image interpretation (24.2 ± 6.2 versus 21.2 ± 5.4), but differences could obey to different attitudes between both groups. The usefulness of virtual lectures to learn General Radiology obtained the highest global scoring (8.82 ± 1.00). Contents were generally better evaluated than the design of the presentations. Conclusion: Virtual lectures can substitute conventional lectures in radiology education for medical students with no detriment to students’ learning. Their potential advantage is that magisterial lectures can be used to discuss contents with students in a more participative way if virtual lectures are provided before.

    The scope of work for this task involves a systems' evaluation, using the Kepner-Tregoe (K-T) decision analysis methodology, of off-gas treatment alternatives for a Process Experimental Pilot Plant (PREPP). Two basic systems were evaluated: (1) a wet treatment system using a quencher and scrubber system; and (2) a dry treatment system using a spray dryer and baghouse arrangement. Both systems would neutralize acidic off-gases (HCL and SO 2 ) and remove radioactive particulates prior to release to the environment. The K-T analysis results provided a numerical comparison of the two basic off-gas treatments systems for PREPP. The overall ratings for the two systems differ by only 7%. The closeness of the evaluation indicates that either system is capable of treating the off-gases from PREPP. Based on the analysis, the wet treatment system design is slightly more favorable for PREPP. Technology development, expected operability, total costs, and safety aspects were determined to be more advantageous for the wet system design. Support technology was the only major category that appears less favorable for using the wet off-gas system for PREPP. When considering the two criteria considered most important for PREPP (capital cost and major accident prevention - both rated 10), the wet treatment system received maximum ratings. Space constraints placed on the design by the existing TAN-607 building configuration also are more easily met by the wet system design. Lastly, the level of development for the wet system indicates more applicable experience for nuclear waste processing

    NASA's Carbon Monitoring System (CMS) flux pilot project combines NASA's Earth System models in land, ocean and atmosphere to track surface CO2 fluxes. The system is constrained by atmospheric measurements of XCO2 from the Japanese GOSAT satellite, giving a "big picture" view of total CO2 in Earth's atmosphere. Combining two land models (CASA-Ames and CASA-GFED), two ocean models (ECCO2 and NOBM) and two atmospheric chemistry and inversion models (GEOS-5 and GEOS-Chem), the system brings together the stand-alone component models of the Earth System, all of which are run diagnostically constrained by a multitude of other remotely sensed data. Here, we evaluate the biospheric land surface CO2 fluxes (i.e., net ecosystem exchange, NEE) as estimated from the atmospheric flux inversion. We compare against the prior bottom-up estimates (e.g., the CASA models) as well. Our evaluation dataset is the independently derived global wall-to-wall MPI-BGC product, which uses a machine learning algorithm and model tree ensemble to "scale-up" a network of in situ CO2 flux measurements from 253 globally-distributed sites in the FLUXNET network. The measurements are based on the eddy covariance method, which uses observations of co-varying fluxes of CO2 (and water and energy) from instruments on towers extending above ecosystem canopies; the towers integrate fluxes over large spatial areas (~1 km2). We present global maps of CO2 fluxes and differences between products, summaries of fluxes by TRANSCOM region, country, latitude, and biome type, and assess the time series, including timing of minimum and maximum fluxes. This evaluation shows both where the CMS is performing well, and where improvements should be directed in further work.

    A full-scale and two pilot-scale upflow sulfur-oxidizing denitrification (SOD) columns were evaluated using metal plating wastewater as feed. The sludge was autotrophically enriched, and inoculated in the SOD columns attached to the effluent line of three metal plating wastewater treatment facilities. The effects of activated carbon and aeration were also studied, and found effective for the removal of suspended solids and ammonia, respectively. The results showed that the constituents, such as the total nitrogen, nitrates, nitrites, ammonia, chemical oxygen demand (COD), and heavy metals, were effectively removed. The pH was observed to be maintained at 7-8 due to the alkalinity supplied by the sulfur-calcium carbonate (SC) pellet. The denitrification efficiency and start-up period were observed to be affected by the influent quality. Chromium, iron, nickel, copper, and zinc--the major heavy metal components of the influent--were effectively reduced at certain concentrations. Other metal ions were also detected and reduced to undetectable concentrations, but no trends in the comparison with denitrification were observed. From the results it can be concluded that SOD is effective for the removal of nitrogen, particularly nitrates, without a drastic pH change, and can effectively remove minute concentrations of heavy metals and COD in metal plating wastewaters.

    The aim of this study was to investigate the effect of spinal anesthesia (SA) on olfactory memory using Brief-Smell Identification TestTM (B-SIT). This, prospective, clinical study was performed on 40 ASA physical status I-III patients, between 18-65 years of age undergoing a planned elective minor surgery under SA. All participants were preoperatively informed about B-SIT and the mode of application of the test according to the information in the book. B-SIT was applied to each patient preoperatively and the scores were recorded. B-SIT was reapplied to all patients on the 1st and 2nd postoperative days and the scores were recorded. Moreover, development of postdural puncture headache (PDPH) and/or neurological symptoms (such as hearing loss, diplopia) were checked. Postoperative headache was observed in 7 of the participants and 3 of them was diagnosed to have PDPH. No statistically significant difference was observed in the olfactory memory evaluation of the patients suffering from headache and the 3 patients diagnosed with PDPH. No statistically significant difference was observed in the correct odor answer ratio between the preoperative and postoperative 1st and 2nd days (p > 0.05). We confirm that SA does not affect olfactory memory. Further studies are necessary to confirm the results of our pilot study in a larger sample.

  1. Evaluation of the Waste Isolation Pilot Plant classification of systems, structures and components

    1985-07-01

    A review of the classification system for systems, structures, and components at the Waste Isolation Pilot Plant (WIPP) was performed using the WIPP Safety Analysis Report (SAR) and Bechtel document D-76-D-03 as primary source documents. The regulations of the US Nuclear Regulatory Commission (NRC) covering ''Disposal of High level Radioactive Wastes in Geologic Repositories,'' 10 CFR 60, and the regulations relevant to nuclear power plant siting and construction (10 CFR 50, 51, 100) were used as standards to evaluate the WIPP design classification system, although it is recognized that the US Department of Energy (DOE) is not required to comply with these NRC regulations in the design and construction of WIPP. The DOE General Design Criteria Manual (DOE Order 6430.1) and the Safety Analysis and Review System for AL Operation document (AL 54f81.1A) were reviewed in part. This report includes a discussion of the historical basis for nuclear power plant requirements, a review of WIPP and nuclear power plant classification bases, and a comparison of the codes and standards applicable to each quality level. Observations made during the review of the WIPP SAR are noted in the text of this reoport. The conclusions reached by this review are: WIPP classification methodology is comparable to corresponding nuclear power procedures. The classification levels assigned to WIPP systems are qualitatively the same as those assigned to nuclear power plant systems

    Full Text Available The recent preparation of the Operation and Maintenance (O&M Manual for Palestinian municipalities is an important step to guide them towards preparing and implementing their O&M priority-based plans, considering scare resources. During the course of preparation of the Manual, the proposed procedures were applied at ten pilot municipalities. This study aims to explore the outcome of the implementation of the 2014 O&M road maintenance plans at these municipalities. To achieve this, analysis of the outcome of a questionnaire designed to collect relevant information from these municipalities was conducted. The results show that seven of the targeted municipalities used the prioritization criteria proposed in the O&M Manual. Despite that the remaining municipalities had the liberty to slightly change the relative weight of the indicators, sensitivity analysis was conducted and indicated robustness of the indicators. The average percentage of roads’ lengths of the actually maintained to the planned was 35%, suggesting that the plans were ambitious and need to be more rational. Most of the allocated funds for road maintenance came from the municipalities own budgets, indicating need to have more financing by the government to ensure the integrity of the municipal road infrastructure assets. The results also indicated that 95% of the maintenance works were executed through external contracts, and that the municipalities need to be supported and equipped to conduct the basic road maintenance works.

    Responsibility for immunisation in Nigeria is decentralised to sub-national governments. So far, they have failed to achieve optimal coverage for their populations. We evaluated a pilot intervention implemented between 2013 and 2014 to redesign a vaccine supply chain management system in Kano, Nigeria. The intervention included financing immunisation services from a designated pool of government and donor funds, a visibility tool to track vaccine stock, and a private vendor engaged to deliver vaccines directly to health facilities. The number of local government areas within the state with adequate vaccine stock increased from 21% to 98% after 10 months. To understand how the intervention achieved this outcome, we analysed immunisation coverage for the period and interviewed 18 respondents across different levels of government. We found that the intervention worked by improving ownership and accountability for immunisation by sub-national governments and their capacity for generating resources and management (of data and the supply chain). While the intervention focused on improving immunisation coverage, we identified gaps in the demand for services. Efforts to improve immunisation coverage and vaccine supply systems should streamline decentralised structures, empower sub-national governments with financial and technical capacity, and promote strategies to improve the demand and use of services.

    To evaluate the success of autogenous transplantation of embedded/impacted third molars harvested using piezosurgery. This prospective pilot study enrolled 20 healthy patients with non-restorable first/second molars and a caries-free retrievable embedded/impacted third molar. Piezosurgery was used for removing inter-radicular bone at the recipient socket as well as for bone removal around the donor teeth. After an average follow-up of 16.4 months (SD = 1.9), 18 cases were successful with formation of periodontal ligament around the teeth. One tooth was lost due to infection at 1 month. One patient was lost to follow-up. There was no root resorption or ankylosis in any of the cases. In six donor teeth with complete root formation, root canal treatment was carried out. All the remaining teeth responded positively with vitality testing. Piezosurgery is an effective device if embedded/impacted third molars are to be harvested for successful autogenous transplantation.

    Full Text Available Much established pedagogical and CALL (computer-assisted language learning research advocates an integrated constructivist approach to the use of technology in language learning. This paper reports on a pilot project delivered to first year undergraduate French students. The project aim was to deliver a blend of collaborative and individual learning through a combination of CALL programs and online activities alongside traditional face-to-face conversation classes. Using quantitative analysis of a pre- and posttest and a variety of questionnaires, this project assessed student progress in developing oral skills across two groups, one (the treatment group using technology and the other (the comparison group being a traditional conversation class. Each group covered the same content and underwent the same assessment procedures. In addition, through qualitative analysis measures, the project evaluated the role played by additional variables in the learning process, as well as student and staff reactions to the two approaches. The study concludes by showing that while progress was made by both groups, the progress made by those not using technology was significantly greater than that made by students using technology over a short-term study. It also highlights the need for developing pedagogy to ensure that CALL-based teaching goes beyond rehearsal activity to achieve message-orientated communication.

    This Excessive sugar-sweetened beverage (SSB) consumption and low health literacy skills have emerged as two public health concerns in the United States (US); however, there is limited research on how to effectively address these issues among adults. As guided by health literacy concepts and the Theory of Planned Behavior (TPB), this randomized controlled pilot trial applied the RE-AIM framework and a mixed methods approach to examine a sugar-sweetened beverage (SSB) intervention (SipSmartER), as compared to a matched-contact control intervention targeting physical activity (MoveMore). Both 5-week interventions included two interactive group sessions and three support telephone calls. Executing a patient-centered developmental process, the primary aim of this paper was to evaluate patient feedback on intervention content and structure. The secondary aim was to understand the potential reach (i.e., proportion enrolled, representativeness) and effectiveness (i.e. health behaviors, theorized mediating variables, quality of life) of SipSmartER. Twenty-five participants were randomized to SipSmartER (n=14) or MoveMore (n=11). Participants' intervention feedback was positive, ranging from 4.2-5.0 on a 5-point scale. Qualitative assessments reavealed several opportunties to improve clarity of learning materials, enhance instructions and communication, and refine research protocols. Although SSB consumption decreased more among the SipSmartER participants (-256.9 ± 622.6 kcals), there were no significant group differences when compared to control participants (-199.7 ± 404.6 kcals). Across both groups, there were significant improvements for SSB attitudes, SSB behavioral intentions, and two media literacy constructs. The value of using a patient-centered approach in the developmental phases of this intervention was apparent, and pilot findings suggest decreased SSB may be achieved through targeted health literacy and TPB strategies. Future efforts are needed to examine

    This paper presents an overview of the flight management work being conducted using NASA Langley's oculometer system. Tests have been conducted in a Boeing 737 simulator to investigate pilot scan behavior during approach and landing for simulated IFR, VFR, motion versus no motion, standard versus advanced displays, and as a function of various runway patterns and symbology. Results of each of these studies are discussed. For example, results indicate that for the IFR approaches a difference in pilot scan strategy was noted for the manual versus coupled (autopilot) conditions. Also, during the final part of the approach when the pilot looks out-of-the-window he fixates on his aim or impact point on the runway and holds this point until flare initiation.

    An Adaptive Augmenting Control (AAC) algorithm for the Space Launch System (SLS) has been developed at the Marshall Space Flight Center (MSFC) as part of the launch vehicle's baseline flight control system. A prototype version of the SLS flight control software was hosted on a piloted aircraft at the Armstrong Flight Research Center to demonstrate the adaptive controller on a full-scale realistic application in a relevant flight environment. Concerns regarding adverse interactions between the adaptive controller and a potential manual steering mode were also investigated by giving the pilot trajectory deviation cues and pitch rate command authority, which is the subject of this paper. Two NASA research pilots flew a total of 25 constant pitch rate trajectories using a prototype manual steering mode with and without adaptive control, evaluating six different nominal and off-nominal test case scenarios. Pilot comments and PIO ratings were given following each trajectory and correlated with aircraft state data and internal controller signals post-flight.

    Full Text Available Abstract Background As more integrative medicine educational content is integrated into conventional family medicine teaching, the need for effective evaluation strategies grows. Through the Integrative Family Medicine program, a six site pilot program of a four year residency training model combining integrative medicine and family medicine training, we have developed and tested a set of competency-based evaluation tools to assess residents' skills in integrative medicine history-taking and treatment planning. This paper presents the results from the implementation of direct observation and treatment plan evaluation tools, as well as the results of two Objective Structured Clinical Examinations (OSCEs developed for the program. Methods The direct observation (DO and treatment plan (TP evaluation tools developed for the IFM program were implemented by faculty at each of the six sites during the PGY-4 year (n = 11 on DO and n = 8 on TP. The OSCE I was implemented first in 2005 (n = 6, revised and then implemented with a second class of IFM participants in 2006 (n = 7. OSCE II was implemented in fall 2005 with only one class of IFM participants (n = 6. Data from the initial implementation of these tools are described using descriptive statistics. Results Results from the implementation of these tools at the IFM sites suggest that we need more emphasis in our curriculum on incorporating spirituality into history-taking and treatment planning, and more training for IFM residents on effective assessment of readiness for change and strategies for delivering integrative medicine treatment recommendations. Focusing our OSCE assessment more narrowly on integrative medicine history-taking skills was much more effective in delineating strengths and weaknesses in our residents' performance than using the OSCE for both integrative and more basic communication competencies. Conclusion As these tools are refined further they will be of value both in improving

    The aim of this study was to determine the content validity, internal consistency, test-retest reliability and inter-rater reliability of the Clinical Competency Evaluation Instrument (CCEVI) in assessing the clinical performance of physiotherapy students. This study was carried out between June and September 2013 at University Kebangsaan Malaysia (UKM), Kuala Lumpur, Malaysia. A panel of 10 experts were identified to establish content validity by evaluating and rating each of the items used in the CCEVI with regards to their relevance in measuring students' clinical competency. A total of 50 UKM undergraduate physiotherapy students were assessed throughout their clinical placement to determine the construct validity of these items. The instrument's reliability was determined through a cross-sectional study involving a clinical performance assessment of 14 final-year undergraduate physiotherapy students. The content validity index of the entire CCEVI was 0.91, while the proportion of agreement on the content validity indices ranged from 0.83-1.00. The CCEVI construct validity was established with factor loading of ≥0.6, while internal consistency (Cronbach's alpha) overall was 0.97. Test-retest reliability of the CCEVI was confirmed with a Pearson's correlation range of 0.91-0.97 and an intraclass coefficient correlation range of 0.95-0.98. Inter-rater reliability of the CCEVI domains ranged from 0.59 to 0.97 on initial and subsequent assessments. This pilot study confirmed the content validity of the CCEVI. It showed high internal consistency, thereby providing evidence that the CCEVI has moderate to excellent inter-rater reliability. However, additional refinement in the wording of the CCEVI items, particularly in the domains of safety and documentation, is recommended to further improve the validity and reliability of the instrument.

  14. Evaluation of the Safety Analysis Report for the Waste Isolation Pilot Plant Project

    1985-05-01

    The Safety Analysis Report (SAR) for the Waste Isolation Pilot Plant (WIPP) Project was first published by the US Department of Energy (DOE), WIPP Project Office (WPO) in 1980. Since that time a total of eight amendments to this Report have been published. As part of its independent evaluation of the WIPP Project for the State of New Mexico, the Environmental Evaluation Group (EEG) maintains a continuing technical assessment of the information in this Report and its amendments. Beginning with the initial publication, and following the amendments, the EEG prepares detailed written comments and recommendations which are submitted to the WPO for consideration in future amendments. The WPO has made many substantial changes to the SAR in response to the EEG's comments. On frequent occasions, meetings between the two groups have been held in an effort to reach an accord on some of the more controversial issues. These meetings generally have been very constructive, but several important areas of conflict remain. In many instances, these areas represent changes which are to be considered by the WPO at some future date, rather than irreconcilable issues. The most important issues remaining to be resolved are included in the discussions of this report, and could be summarized as follows: (1) An amendment of the topical content to be more in accord with the DOE Order 5481.1A and AL 5481.1A. (2) Substantial revisions of the classification of components, structures and systems, and related quality assurance. (3) Revisions to the site geological and hydrologic data based on studies agreed to between DOE and the State

    Polycystic ovary syndrome (PCOS) is a chronic endocrine syndrome in reproductive-aged women which is very common among Aboriginal and Torres Strait Islander women. The objective of this study was to conduct a process evaluation of a pilot clinic on Thursday Island which aimed to provide a comprehensive evidence-based service for women with PCOS throughout the Torres Strait. Mixed-method evaluation at 12 months comprising a medical record audit, semi-structured interviews and focus group discussions. Primary care. Audit of n = 11 clinics (n = 36 women), qualitative semi-structured interviews with n = 8 clinicians and focus group discussions with n = 8 women. (i) Fidelity to evidence-based guidelines, (ii) barriers and enablers to women using the service, (iii) the ability to meet the needs of women and the community. The clinic was largely successful in providing evidence-based care with up to 78% of women receiving recommended cardiometabolic screening, 100% emotional screening and 89% lifestyle management despite the remoteness of the clinic and limited financial and human resources. Health care providers report sustainability of the clinic will be dependent on factors including staffing, administrative support and inclusion of Aboriginal and Torres Strait Islander health workers. While the clinic has been largely successful there are areas identified for potential improvement and to facilitate sustainability which should be considered before up-scaling this model to a national level. These include systems, administrative and staffing support, engaging with other community services to facilitate lifestyle changes and ongoing engagement and upskilling of Aboriginal and Torres Strait Islander health care providers. © 2016 National Rural Health Alliance Inc.

    We have initiated a multi-institutional phase I trial of 5-fraction stereotactic body radiotherapy (SBRT) for Stage III-IVa laryngeal cancer. We conducted this pilot dosimetric study to confirm potential utility of online adaptive replanning to preserve treatment quality. We evaluated ten cases: five patients enrolled onto the current trial and five patients enrolled onto a separate phase I SBRT trial for early-stage glottic larynx cancer. Baseline SBRT treatment plans were generated per protocol. Daily cone-beam CT (CBCT) or diagnostic CT images were acquired prior to each treatment fraction. Simulation CT images and target volumes were deformably registered to daily volumetric images, the original SBRT plan was copied to the deformed images and contours, delivered dose distributions were re-calculated on the deformed CT images. All of these were performed on a commercial treatment planning system. In-house software was developed to propagate the delivered dose distribution back to reference CT images using the deformation information exported from the treatment planning system. Dosimetric differences were evaluated via dose-volume histograms. We could evaluate dose within 10 minutes in all cases. Prescribed coverage to gross tumor volume (GTV) and clinical target volume (CTV) was uniformly preserved; however, intended prescription dose coverage of planning treatment volume (PTV) was lost in 53% of daily treatments (mean: 93.9%, range: 83.9-97.9%). Maximum bystander point dose limits to arytenoids, parotids, and spinal cord remained respected in all cases, although variances in carotid artery doses were observed in a minority of cases. Although GTV and CTV SBRT dose coverage is preserved with in-room three-dimensional image guidance, PTV coverage can vary significantly from intended plans and dose to critical structures may exceed tolerances. Online adaptive treatment re-planning is potentially necessary and clinically applicable to fully preserve treatment

    Background Previous research has suggested that comprehensive teenage pregnancy prevention programs that address sexual education and life skills development and provide academic are effective in reducing births among enrolled teenagers. However, there have been limited data on costs and cost-effectiveness of such programs. Objectives To use a community-based participatory research approach, to develop estimates of the cost-benefit of the Pathways/Senderos Center, a comprehensive neighborhood-based program to prevent unintended pregnancies and promote positive development for adolescents. Methods Using data from 1997-2003, we conducted an in-time intervention analysis to determine program cost-benefit while teenagers were enrolled and then used an extrapolation analysis to estimate accyrred economibc benefits and cost-benefit up to age 30. Results The program operating costs totaled $3,228,152.59 and reduced the teenage childbearing rate from 94.10 to 40.00 per 1000 teenage females, averting $52,297.84 in total societal costs, with an economic benefit to society from program participation of $2,673,153.11. Therefore, total costs to society exceeded economic benefits by $559,677.05, or $1,599.08 per adolescent per year. In an extrapolation analysis, benefits to society exceed costs by $10,474.77 per adolescent per year by age 30 on average, with social benefits outweighing total social costs by age 20.1. Conclusions We estimate that this comprehensive teenage pregnancy prevention program would provide societal economic benefits once participants are young adults, suggesting the need to expand beyond pilot demonstrations and evaluate the long-range cost-effectiveness of similarly comprehensive programs when implemented more widely in high-risk neighborhoods.

    Mental health problems are common among prison inmates. Music therapy has been shown to reduce mental health problems. It may also be beneficial in the rehabilitation of prisoners, but rigorous outcome research is lacking. We compared group music therapy with standard care for prisoners in a pilot randomised controlled trial that started with the establishment of music therapy services in a prison near Bergen in 2008. In all, 113 prisoners agreed to participate. Anxiety (STAI-State [State-Trait Anxiety Inventory], STAI-Trait), depression (HADS-D [Hospital Anxiety and Depression Scale]), and social relationships (Quality of Life Enjoyment and Satisfaction Questionnaire [Q-LES-Q]) were assessed at baseline; every 2 weeks in the experimental group; after 1, 3, and 6 months in the control group; and at release. No restrictions were placed on the frequency, duration, or contents of music therapy. Duration of stay in the institution was short (62% stayed less than 1 month). Only a minority reached clinical cutoffs for anxiety and depression at baseline. Between-group analyses of effects were not possible. Music therapy was well accepted and attractive among the prisoners. Post hoc analysis of within-group changes suggested a reduction of state anxiety after 2 weeks of music therapy (d = 0.33, p = .025). Short sentences and low baseline levels of psychological disturbance impeded the examination of effects in this study. Recommendations for planning future studies are given, concerning the careful choice of participants, interventions and settings, comparison condition and design aspects, choice of outcomes, and integration of research approaches. Thus, the present study has important implications for future studies evaluating interventions for improving prisoners' mental health. ISRCTN22518605. © The Author(s) 2013.

    Externalizing problems, which are the main reason for youth referrals to mental health agencies, are highly persistent and predict a range of negative outcomes. Youths with externalizing problems are also frequently comorbid with anxiety. Among the most widely recognized evidence-based treatments is cognitive behavioral therapy (CBT). Although CBT principles seem to be sound, effect sizes remain moderate, suggesting improvements could be made to this conventional treatment approach. The main premise of the current pilot study is to investigate the feasibility of implementing a videogame intervention ("Dojo" [Gamedesk, Los Angeles, CA]) that incorporates CBT principles and aims to address the limitations of conventional CBT delivery models, with the ultimate goal of improving outcomes for this difficult-to-treat population. "Dojo" is an emotion management game that helps youths to recognize and control their physiological and emotional arousal. We explored the implementation and user experience of "Dojo" in a sample of eight adolescents in residential treatment for both externalizing and anxiety problems. Participants attended all sessions without complaints. They evaluated "Dojo" very positively and exhibited high compliance during the training sessions. We encountered some problems with session scheduling and obtaining mentor reports. Quantitative data show the predicted decrease in three out of four measurements. The smooth implementation, high user satisfaction, high self-reported compliance during training sessions, and initial outcome results all indicate the high potential "Dojo" holds as an innovative intervention. If additional rigorously designed randomized controlled trials prove to be successful, "Dojo" can be a cost-effective way to engage high-risk youths in effective intervention.

    Ultrapure soft water (UPSW) is water in which calcium and magnesium ions have been replaced with sodium ions using a cation-exchange resin. We recently demonstrated that washing with soap and UPSW reduced the clinical severity of dermatitis and improved the skin barrier function in NC/NgaTnd mice, a murine model for human atopic dermatitis. The purpose of this pilot study was to evaluate the efficacy of shampoo treatment with UPSW for dogs with pruritus. Eleven dogs with pruritus were randomly assigned to two groups depending on whether they received weekly shampoo treatment with UPSW or tap water for 4 weeks. After a washout period, the treatment protocol was switched such that each dog received both treatments. The pre-treatment and post-treatment values of the following were compared: pruritus scores assessed by the owners; dermatitis scores recorded by an investigator; and transepidermal water loss (TEWL). Shampoo treatment with UPSW significantly decreased pruritus and dermatitis scores in the dogs, whereas shampoo treatment with tap water did not. In addition, shampoo treatment with UPSW, but not with tap water, significantly reduced TEWL in the dogs. Adverse events due to the treatment were not observed in the dogs. Furthermore, we found that topical application of UPSW for barrier-disrupted skin caused by tape stripping in healthy dogs decreased TEWL more rapidly than topical application of tap water. Our findings suggest that shampoo treatment with UPSW promotes skin barrier recovery and thus could be considered as a possible therapeutic option in the management of pruritus and dermatitis in dogs. © 2010 The Authors.

    In vitro and in situ studies have demonstrated that the photodynamic antimicrobial therapy (PACT) is effective in reducing Streptococcus mutans population in artificially carious dentin. This pilot in vivo study evaluated the antimicrobial effect of PACT using toluidine blue O (TBO) and a light-emitting diode (LED) in carious dentin lesions. Five healthy adult volunteers (19-36 yr), with at least 4 active carious cavities each, participated in this study. Teeth of each volunteer were randomly divided into four groups: (1) without TBO and without light (Control); (2) with TBO alone (TBO); (3) with LED at 94/J cm2 alone (LED); and (4) with TBO plus LED at 94 J/cm2 (PACT). Each cavity was divided into two halves. The baseline carious dentin sample was collected from half of each cavity. Following, the treatments were performed using a random distribution of tooth into treatments. Then, the second collection of carious dentin samples was performed. Before and after treatments, dentin samples were analyzed with regard to the counts of total viable microorganisms, total streptococci, mutans streptococci, and lactobacilli. The data were statistically analyzed by Kruskal-Wallis and Student-Newman-Keuls tests (α=5%). Log reductions ranged from -0.12 to 2.68 and significant reductions were observed for PACT (group 4) when compared to the other groups (1, 2, and 3) for total streptococci and mutans streptococci. Concluding, PACT was effective in killing oral microorganisms present in in vivo carious dentin lesions and may be a promising technique for eliminating bacteria from dentin before restoration.

    Previous research has suggested that comprehensive teenage pregnancy prevention programs that address sexual education and life skills development and provide academic support are effective in reducing births among enrolled teenagers. However, there have been limited data on the costs and cost effectiveness of such programs. The study used a community-based participatory research approach to develop estimates of the cost-benefit of the Pathways/Senderos Center, a comprehensive neighborhood-based program to prevent unintended pregnancies and promote positive development for adolescents. Using data from 1997-2003, an in-time intervention analysis was conducted to determine program cost-benefit while teenagers were enrolled; an extrapolation analysis was then used to estimate accrued economic benefits and cost-benefit up to age 30 years. The program operating costs totaled $3,228,152.59 and reduced the teenage childbearing rate from 94.10 to 40.00 per 1000 teenage girls, averting $52,297.84 in total societal costs, with an economic benefit to society from program participation of $2,673,153.11. Therefore, total costs to society exceeded economic benefits by $559,677.05, or $1599.08 per adolescent per year. In an extrapolation analysis, benefits to society exceed costs by $10,474.77 per adolescent per year by age 30 years on average, with social benefits outweighing total social costs by age 20.1 years. This comprehensive teenage pregnancy prevention program is estimated to provide societal economic benefits once participants are young adults, suggesting the need to expand beyond pilot demonstrations and evaluate the long-range cost effectiveness of similarly comprehensive programs when they are implemented more widely in high-risk neighborhoods.

    This study was conducted to evaluate the pilot-scale production of microencapsulated in a 500-L fermenter using emulsion and gelation and to assess the effect of the products on the growth performance, antioxidant activity, immune function, and cecal microbiota in Arbor Acres broilers. A total of seven hundred 1-d-old male Arbor Acres broilers were randomly assigned to 7 dietary treatments with 5 replicate pens per treatment and 20 broilers per pen. The dietary treatments were as follows: 1) basal diet (CON), 2) basal diet containing 0.1% Aureomycin (ANT), 3) basal diet containing unencapsulated at a dose of 1 × 10 cfu/kg of feed (P1), 4) basal diet containing unencapsulated at a dose of 1 × 10 cfu/kg of feed (P2), 5) basal diet containing 0.01% empty microcapsules (CAP), 6) basal diet containing microencapsulated at a dose of 1 × 10 cfu/kg of feed (CAPP1), and 7) basal diet containing microencapsulated at a dose of 1 × 10 cfu/kg of feed (CAPP2). The feeding experiment included 2 phases: the starter phase from d 1 to 21 and the grower phase from d 22 to 42. The results showed that a 500-L fermenter could produce 20.73 ± 4.05 kg of microcapsules with an approximate diameter of 549 μm. The feeding experiment showed that ADG of broilers in CAPP1 was significantly ( microencapsulation of microbial cells can be achieved using emulsion and initial gelation and that the dietary administration of microencapsulated can significantly enhance the growth performance, immune function, cecum microbial community, and overall health of broilers.

    This report, Vol. II, presents a discussion of the operations of the ten EES pilot state programs during the period from October 1, 1977 through September 30, 1979. Each of the ten pilot states - Alabama, Connecticut, Michigan, New Mexico, Pennsylvania, Tennessee, Texas, Washington, Wisconsin, and Wyoming - received a grant of approximately $1.1 million to develop and implement an 18-month program beginning on October 1, 1977. In September 1978, each State received an additional $370,000 for service-delivery programs for the extension of the pilot program, April 1979 through September 1979. A case-study description of the operations of the pilot program in each State is provided here, with special attention given to the two programs selected in each State for more-detailed study and survey research. Although the thrust of this volume is descriptive, some survey data and analyses are presented for the emphasis programs. Two telephone surveys of clients and a non-client sample were conducted, one at the end of the first year of the pilot program (October 1977 - September 1978) and one at the end of the second year (October 1978 - September 1979).

    Engineering development and qualification of a Research Flight Control System (RFCS) for the Rotorcraft Aircrew Systems Concepts Airborne Laboratory (RASCAL) JUH-60A has motivated the development of a pilot rating scale for evaluating failure transients in fly-by-wire flight control systems. The RASCAL RFCS includes a highly-reliable, dual-channel Servo Control Unit (SCU) to command and monitor the performance of the fly-by-wire actuators and protect against the effects of erroneous commands from the flexible, but single-thread Flight Control Computer. During the design phase of the RFCS, two piloted simulations were conducted on the Ames Research Center Vertical Motion Simulator (VMS) to help define the required performance characteristics of the safety monitoring algorithms in the SCU. Simulated failures, including hard-over and slow-over commands, were injected into the command path, and the aircraft response and safety monitor performance were evaluated. A subjective Failure/Recovery Rating (F/RR) scale was developed as a means of quantifying the effects of the injected failures on the aircraft state and the degree of pilot effort required to safely recover the aircraft. A brief evaluation of the rating scale was also conducted on the Army/NASA CH-47B variable stability helicopter to confirm that the rating scale was likely to be equally applicable to in-flight evaluations. Following the initial research flight qualification of the RFCS in 2002, a flight test effort was begun to validate the performance of the safety monitors and to validate their design for the safe conduct of research flight testing. Simulated failures were injected into the SCU, and the F/RR scale was applied to assess the results. The results validate the performance of the monitors, and indicate that the Failure/Recovery Rating scale is a very useful tool for evaluating failure transients in fly-by-wire flight control systems.

    Children with autistic spectrum disorder (ASD) often have associated behavioural difficulties that can present a challenge for parents and parenting. There are several effective social learning theory-based parenting programmes for dealing with behavioural difficulties, including the Incredible Years (IY) parent programmes. However, these programmes typically do not specifically target parents of children with ASD. Recently, a new addition to the IY suite of programmes known as the IY Autistic Spectrum and Language Delays (IY-ASLD) parent programme was developed. The main aims of the present study are to examine the feasibility of delivering this programme within child health services and to provide initial evidence for effectiveness and economic costs. The Parenting for Autism, Language, And Communication Evaluation Study (PALACES) trial is a pragmatic, multicentre, pilot randomised controlled trial comparing the IY-ASLD programme with a wait-list control condition. 72 parents of children with ASD (aged 3-8 years) will be randomly allocated to either the intervention or control condition. Data will be collected prior to randomisation and 6 months postrandomisation for all families. Families in the intervention condition only will also be followed up at 12 and 18 months postrandomisation. This study will provide initial evidence of effectiveness for the newly developed IY-ASLD parenting programme. It will also add to the limited economic evidence for an intervention targeting parents of children with ASD and provide longer term data, an important component for evaluations of parenting programmes. Approval for the study was granted by the Research Ethics Committee at the School of Psychology, Bangor University (reference number: 2016-15768) and the North Wales Research Ethics Committee, UK (reference number: 16/WA/0224). The findings will be disseminated through research conferences and peer-reviewed journals. ISRCTN57070414; Pre-results. Published by the BMJ

    Therapeutic inertia (TI) is a recent concept still unknown by many physicians. In chronic diseases such as hypertension, it is defined as the tendency of physicians not to increase or change antihypertensive medications when the target blood pressure is not reached. Acting on TI could improve blood pressure control in France. This was a single-center prospective pilot study conducted by hypertension specialist physicians at the University Cardio-Vascular Center in Lille (France). It was conducted between March and June 2011. Data was collected from 161 hypertensive patients (mean age: 61.64±11.18 years; 98 (60.9%) male; 75 secondary prevention patients). Each physician completed a questionnaire on therapeutic inertia. TI was defined as a consultation in which treatment change was indicated (systolic blood pressure [BP]≥140 and/or diastolic BP≥90mmHg in all patients), but did not occur, with absence of an adapted justification of this choice. We considered as an adapted justification: a white coat effect demonstrated by ambulatory blood pressure monitoring (ABPM) or home blood pressure monitoring; scheduled reassessment of the BP by ABPM; recent change in antihypertensive treatment (less than 4 weeks); hospitalization needed for complete evaluation of secondary causes of hypertension and a more detailed assessment of potential target organ damage in patients with grade 1 or 2 hypertension. Our study aimed to evaluate rates of TI, to identify factors associated with TI, and to test the TI questionnaire. Therapeutic inertia as defined in this study occurred in 11 consultations (8.3%) of the 133 hypertensive patients having uncontrolled BP above or equal to 140 and/or 90mmHg. Significant factors associated with TI were older age (Z=2.35, PP>0.05) and the number of consultations (Z=1.92, 0.1>P>0.05) exhibited a significant trend to be associated with TI. Although the rate of TI was low in our study conducted in a specialized center, a well-accepted definition of

    An adaptive augmenting control algorithm for the Space Launch System has been developed at the Marshall Space Flight Center as part of the launch vehicles baseline flight control system. A prototype version of the SLS flight control software was hosted on a piloted aircraft at the Armstrong Flight Research Center to demonstrate the adaptive controller on a full-scale realistic application in a relevant flight environment. Concerns regarding adverse interactions between the adaptive controller and a proposed manual steering mode were investigated by giving the pilot trajectory deviation cues and pitch rate command authority.

    The control automation and interaction paradigm (e.g., manual, autopilot, flight management system) used on virtually all large highly automated aircraft has long been an exemplar of breakdowns in human factors and human-centered design. An alternative paradigm is the Haptic Flight Control System (HFCS) that is part of NASA Langley Research Center s Naturalistic Flight Deck Concept. The HFCS uses only stick and throttle for easily and intuitively controlling the actual flight of the aircraft without losing any of the efficiency and operational benefits of the current paradigm. Initial prototypes of the HFCS are being evaluated and this paper describes one such evaluation. In this evaluation we examined claims regarding improved situation awareness, appropriate workload, graceful degradation, and improved pilot acceptance. Twenty-four instrument-rated pilots were instructed to plan and fly four different flights in a fictitious airspace using a moderate fidelity desktop simulation. Three different flight control paradigms were tested: Manual control, Full Automation control, and a simplified version of the HFCS. Dependent variables included both subjective (questionnaire) and objective (SAGAT) measures of situation awareness, workload (NASA-TLX), secondary task performance, time to recognize automation failures, and pilot preference (questionnaire). The results showed a statistically significant advantage for the HFCS in a number of measures. Results that were not statistically significant still favored the HFCS. The results suggest that the HFCS does offer an attractive and viable alternative to the tactical components of today s FMS/autopilot control system. The paper describes further studies that are planned to continue to evaluate the HFCS.

    For recovery of rare mineral resources such as lithium or boron from seawater, the lithium adsorbent material have been made by Korea Institute of Geoscience and Mineral Resources (KIGAM) and pilot plant was conducted in Okgye Harbor, Gangneung, Korea. The application of lithium adsorbent in pilot plant, it is important to consider the impact on the marine environment. Especially phytoplankton communities are important marine microorganism to represent marine primary product. At the same time, phytoplankton is possible to induce the decrease of lithium recovery rate due to cause of biofouling to surfaces of lithium adsorbents. Therefore long-term and periodic monitoring of phytoplankton is necessary to understand the environmental impact and biofouling problems near the lithium pilot plant. The abundance and biomass of phytoplankton have been evaluated through monthly interval sampling from February 2013 to May 2015. Abundance and species diversity of phytoplankton went up to summer from winter. When lithium adsorbents were immersing to seawater, eco-toxicities of released substances were determined using Microtox with bioluminescence bacteria Vibrio fischeri. The adsorbents were soaked in sterilized seawater and aeration for 1, 3, 5, 7, 10 and 14 days intervals under controlled temperature. Maximum EC50 concentration was 61.4% and this toxicity was showed in more than 10 days exposure.

    High-temperatures in the cockpit environment can adversely influence pilot behavior and performance. To investigate the impact of high thermal environments on Chinese pilot performance in a simulated cockpit environment. Ten subjects volunteered to participate in the tests under 40°C and 45°C high-temperature simulations in an environmentally controlled chamber. Measures such as grip strength, perception, dexterity, somatic sense reaction, and analytical reasoning were taken. The results were compared to the Combined Index of Heat Stress (CIHS). CIHS exceeded the heat stress safety limit after 45 min under 40°C, grip strength decreased by 12% and somatic perception became 2.89 times larger than the initial value. In the case of 45°C, CIHS exceeded the safety limit after only 20 min, while the grip strength decreased just by 3.2% and somatic perception increased to 4.36 times larger than the initial value. Reaction and finger dexterity were not statistically different from baseline measurements, but the error rate of analytical reasoning test rose remarkably. Somatic perception was the most sensitive index to high-temperature, followed by grip strength. Results of this paper may help to improve environmental control design of new fighter cockpit and for pilot physiology and cockpit environment ergonomics research for Chinese pilots.

    This research concentrates the design, construction and evaluation of simulated pilot scale landfill lysimeter at KUET campus, Khulna, Bangladesh. Both the aerobic and anaerobic conditions having a base liner and two different types of cap liner were simulated. After the design of a reference cell, the construction of landfill lysimeter was started in January 2008 and completed in July 2008. In all construction process locally available civil construction materials were used. The municipal solid waste (MSW) of 2800-2985 kg having the total volume of 2.80 m(3) (height 1.6 m) and moisture content of 65% was deposited in each lysimeter by applying required compaction energy. In contrast, both the composition in terms of methane (CH(4)), carbon dioxide (CO(2)) and oxygen (O(2)) as well as the flow rate of landfill gas (LFG) generated from MSW in landfill lysimeter were measured and varied significantly in relation to the variation of lysimeter operational condition. Moreover, anaerobic lysimeter-C shows the highest composition of LFG in compare to the anaerobic lysimeter-B due to the providing of lower compaction of cap liner in anaerobic lysimeter-C. Here, it is interesting to note that in absence of compacted clay liner (CCL) and hence percolation of rainwater that facilitates rapid degradation of MSW in aerobic lysimeter-A has resulted in the highest settlement than that of anaerobic landfill lysimeter-B and C. Moreover, in case of anaerobic lysimeter-B and C, the leachate generation was lower than that of aerobic lysimeter-A due to the providing of cap liner in anaerobic lysimeter-B and C, played an important role to reduce the percolation of rainwater. The study also reveals that the leachate pollution index (LPI) has decreased in relation to the increasing of elapsed period as well as the LPI for collection system of aerobic lysimeter-A was higher than that of the collection system of anaerobic lysimeter-B and C. Finally, it can be depicted that LPI for lysimeter

    Bangor University, Brigantia Building, College Road, Bangor, LL57 2AS, UK INTRODUCTION: The COPING parent online universal programme is a web-based parenting intervention for parents of children aged 3-8 years with an interest in positive parenting. The programme focuses on strengthening parent-child relationships and encouraging positive child behaviour. This trial will evaluate whether the intervention is effective in increasing the use of positive parenting strategies outlined in the programme using parent report and blind observation measures. This is a pilot randomised controlled trial with intervention and wait-list control conditions. The intervention is a 10-week online parenting programme to promote positive parent-child relations by teaching core social learning theory principles that encourage positive child behaviour, primarily through the use of praise and rewards. Health visitors and school nurses will circulate a recruitment poster to parents of children aged 3-8 years on their current caseloads. Recruitment posters will also be distributed via local primary schools and nurseries. Parents recruited to the trial will be randomised on a 2:1 ratio to intervention or wait-list control conditions (stratified according to child gender and age). The primary outcome measure is positive parenting as measured by a behavioural observation of parent-child interactions using the Dyadic Parent-Child Interaction Coding System. Secondary outcomes include parent report of child behaviour, and self-reported parental sense of competence, parenting behaviour and parental mental health. Data will be collected at baseline and 3 months later (postintervention) for all participants and 6 months postbaseline for the intervention group only. Analysis of covariance will be the main statistical method used. The trial has received ethical approval from the NHS Betsi Cadwaladr University Health Board Ethics Committee (REC) and the School of Psychology, Bangor University REC (15

    Interprofessional education (IPE) interventions are not always successful in achieving learning outcomes. Team-Based Learning (TBL) would appear to be a suitable pedagogical method for IPE, as it focuses on team performance; however, little is known about interprofessional TBL as an instructional framework for patient safety. In this pilot-study, we aimed to (1) describe participants' reactions to TBL, (2) observe their achievement with respect to interprofessional education learning objectives, and (3) document their attitudinal shifts with regard to patient safety behaviours. We developed and implemented a three-day course for pre-qualifying, non-medical healthcare students to give instruction on non-technical skills related to 'learning from errors'. The course consisted of three sequential modules: 'Recognizing Errors', 'Analysing Errors', and 'Reporting Errors'. The evaluation took place within a quasi-experimental pre-test-post-test study design. Participants completed self-assessments through valid and reliable instruments such as the Mennenga's TBL Student Assessment Instrument and the University of the West of England's Interprofessional Questionnaire. The mean scores of the individual readiness assurance tests were compared with the scores of the group readiness assurance test in order to explore if students learned from each other during group discussions. Data was analysed using descriptive (i.e. mean, standard deviation), parametric (i.e. paired t-test), and non-parametric (i.e. Wilcoxon signed-rank test) methods. Thirty-nine students from five different bachelor's programs attended the course. The participants positively rated TBL as an instructional approach. All teams outperformed the mean score of their individual members during the readiness assurance process. We observed significant improvements in 'communication and teamwork' and 'interprofessional learning' but not in 'interprofessional interaction' and 'interprofessional relationships

    To conduct an independent, external evaluation of a Scotland-wide youth cessation pilot programme, focusing upon service uptake and effectiveness. National Health Service (NHS) Health Scotland and Action on Smoking and Health (ASH) Scotland funded a 3-year (2002-2005) national pilot programme comprising eight projects which aimed to engage with and support young smokers (aged 12-25 years) to quit. Process evaluation was undertaken via detailed case studies comprising qualitative interviews, observation and documentary analysis. Outcomes were assessed by following project participants (n=470 at baseline) at 3 and 12 months and measuring changes in smoking behaviour, including carbon monoxide (CO)-validated quit status. Recruitment proved difficult. Considerable time and effort were needed to attract young smokers. Advertising and recruitment had to be tailored to project settings and educational activities proved essential to raise the profile of smoking as an issue. Thirty-nine participants [8.6%, 95% confidence interval (CI) 5.0-11.2%] were CO-validated quitters at 3 months and 11 of these (2.4%, 95% CI 1.90-3.8%) were also validated quitters at 12 months. Older participants were more likely to be abstinent at 3 months. The overall quit rate was disappointing. As a result of low participant numbers, it was impossible to draw conclusions about the relative effectiveness of different project approaches. These findings give little support to the case for developing dedicated youth cessation services in Scotland. They also highlight the difficulties of undertaking 'real-world' evaluations of pilot youth cessation projects. More action is needed to develop environments which enhance young smokers' motivation to quit and their ability to sustain quit attempts.

    1997-02-01

    DOE 5480.23, Nuclear Safety Analysis Reports, requires that the US Department of Energy conduct an independent, defensible, review in order to approve a Safety Analysis Report (SAR). That review and the SAR approval basis is documented in this formal Safety Evaluation Report (SER). This SER documents the DOE's review of the Waste Isolation Pilot Plant SAR and provides the Carlsbad Area Office Manager, the WIPP SAR approval authority, with the basis for approving the safety document. It concludes that the safety basis documented in the WIPP SAR is comprehensive, correct, and commensurate with hazards associated with planned waste disposal operations

    Few programs exist to address Intimate Partner Violence (IPV) in Guinea. In 2014, Engender Health, in partnership with the local health authorities in Conakry, Guinea, piloted an integrated approach to IPV screening and counseling, within an existing family planning clinic. This article describes both the process of formulating and implementing this approach, as well as the results of an evaluation of the program. From January to June of 2014, Engender Health staff trained midwives at the Conakry International Planned Parenthood Federation family planning clinic staff in screening and counseling client for IPV. Program evaluators used project records, interview with program staff (n=3), midwives (n=3) and client exit interviews (n=53) to measure the outcomes of this pilot project. Regardless of their IPV status, clients appreciated having a venue in which to discuss IPV. Program staff also felt empowered by the additional training and support for IPV screening. The evaluation yielded valuable suggestions for improvement, including more time for staff training and mock client interview practice, additional skills in counseling, and stronger referral links for women who screen positive for IPV. Integrating IPV screening into family planning services is an important and feasible method for reaching vulnerable women with IPV services.

    Full Text Available Aims. Homonymous hemianopia (HH, a severe visual consequence of stroke, causes difficulties in detecting obstacles on the nonseeing (blind side. We conducted a pilot study to evaluate the effects of oblique peripheral prisms, a novel development in optical treatments for HH, on detection of unexpected hazards when driving. Methods. Twelve people with complete HH (median 49 years, range 29–68 completed road tests with sham oblique prism glasses (SP and real oblique prism glasses (RP. A masked evaluator rated driving performance along the 25 km routes on busy streets in Ghent, Belgium. Results. The proportion of satisfactory responses to unexpected hazards on the blind side was higher in the RP than the SP drive (80% versus 30%; P=0.001, but similar for unexpected hazards on the seeing side. Conclusions. These pilot data suggest that oblique peripheral prisms may improve responses of people with HH to blindside hazards when driving and provide the basis for a future, larger-sample clinical trial. Testing responses to unexpected hazards in areas of heavy vehicle and pedestrian traffic appears promising as a real-world outcome measure for future evaluations of HH rehabilitation interventions aimed at improving detection when driving.

    Knowledge and prediction of mixing and mass transfer in agitated bioreactors is fundamental for process development and scale up. In particular key process parameters such as mixing time and volumetric mass transfer coefficient are essential for bioprocess development. In this work the mixing...... and mass transfer performance of a high power agitated pilot scale bioreactor has been characterized using a novel combination of computational fluid dynamics (CFD) and experimental investigations. The effect of turbulence inside the vessel was predicted using a standard RANS k-ε model. Mixing time...... transfer coefficients were in accordance with the experimental data. This work illustrates the possibility of predicting the two phase fluid dynamic performance of an agitated pilot scale bioreactor using validated CFD models. These models can be applied to illustrate the effect of changing the physical...

    The removal of phosphate as magnesium ammonium phosphate (MAP, struvite) has gained a lot of attention. A novel approach using ureolytic MAP crystallization (pH increase by means of bacterial ureases) has been tested on the anaerobic effluent of a potato processing company in a pilot plant and compared with NuReSys(®) technology (pH increase by means of NaOH). The pilot plant showed a high phosphate removal efficiency of 83 ± 7%, resulting in a final effluent concentration of 13 ± 7 mg · L(-1) PO(4)-P. Calculating the evolution of the saturation index (SI) as a function of the remaining concentrations of Mg(2+), PO(4)-P and NH(4)(+) during precipitation in a batch reactor, resulted in a good estimation of the effluent PO(4)-P concentration of the pilot plant, operating under continuous mode. X-ray diffraction (XRD) analyses confirmed the presence of struvite in the small single crystals observed during experiments. The operational cost for the ureolytic MAP crystallization treating high phosphate concentrations (e.g. 100 mg · L(-1) PO(4)-P) was calculated as 3.9 € kg(-1) P(removed). This work shows that the ureolytic MAP crystallization, in combination with an autotrophic nitrogen removal process, is competitive with the NuReSys(®) technology in terms of operational cost and removal efficiency but further research is necessary to obtain larger crystals.

    Two human-in-the-loop simulation experiments were conducted in coordinated fashion to investigate the allocation of separation assurance functions between ground and air and between humans and automation. The experiments modeled a mixed-operations concept in which aircraft receiving ground-based separation services shared the airspace with aircraft providing their own separation service (i.e., self-separation). Ground-based separation was provided by air traffic controllers without automation tools, with tools, or by ground-based automation with controllers in a managing role. Airborne self-separation was provided by airline pilots using self-separation automation enabled by airborne surveillance technology. The two experiments, one pilot-focused and the other controller-focused, addressed selected key issues of mixed operations, assuming the starting point of current-day operations and modeling an emergence of NextGen technologies and procedures. In the controller-focused experiment, the impact of mixed operations on controller performance was assessed at four stages of NextGen implementation. In the pilot-focused experiment, the limits to which pilots with automation tools could take full responsibility for separation from ground-controlled aircraft were tested. Results indicate that the presence of self-separating aircraft had little impact on the controllers' ability to provide separation services for ground-controlled aircraft. Overall performance was best in the most automated environment in which all aircraft were data communications equipped, ground-based separation was highly automated, and self-separating aircraft had access to trajectory intent information for all aircraft. In this environment, safe, efficient, and highly acceptable operations could be achieved for twice today's peak airspace throughput. In less automated environments, reduced trajectory intent exchange and manual air traffic control limited the safely achievable airspace throughput and

    Use the Community Readiness Model (CRM) to develop and evaluate a contextually appropriate pilot culinary training program for school nutrition staff members. Mixed methods to guide intervention development. Six school districts in rural and urban areas of a southwestern state. School nutrition staff (n = 36; female; 20 years' experience). Pre- and post-training assessments used the CRM. Findings from the pre-assessment were used to develop the pilot culinary training intervention. Readiness to integrate new food preparation methods into existing practices. The researchers used t and Wilcoxon tests to compare overall readiness and dimension scores (P ≤ .05). Thematic analysis was used to identify themes from the discussion component of the assessments. Overall readiness increased from vague awareness to preparation (P = .02). Improved dimensions were knowledge of efforts (P = .004), leadership (P = .05), and knowledge of issues (P = .04). Themes included barriers, leadership, and motivation. The CRM was useful for developing and evaluating a contextually appropriate and effective culinary training program for school nutrition staff. Future efforts should address the provision of additional resources such as on-site chefs, small equipment grants, and engaging school stakeholders.

    This paper reports on a recent successful pilot-scale evaluation of the Ultra-Clean Process performance at a 10-ton/day coal gasifier facility. In these tests, carbonaceous feedstocks were gasified, using GTI's fluidized bed U-GAS{reg_sign} gasification technology, to generate syngas. The raw syngas was then conditioned and fed to the UCP test section for deep cleaning to meet very stringent cleaning requirements for chemical feedstocks or liquid-fuel synthesis applications, or for fuel-cell power generation. Fine particle sorbents for sulfur, halide, and mercury removal were injected into the syngas upstream of two stages of particulate controlled devices, 'barrier filter-reactors', coupling efficient particle capture with an effective entrained and filter cake reaction environment for very effective multiple contaminant removal. The goal of the test program was to confirm sorbent selection, filter-reactor operating parameters and sorbent-to-contaminant ratios, which were previously determined in the laboratory to have potential to reduce contaminant concentrations to very low levels. The pilot-scale data developed are being used to update conceptual evaluations, which have shown the technical feasibility, cost effectiveness and commercial merit for the Ultra-Clean Process compared to conventional, Rectisol-based syngas cleaning. 10 refs., 5 figs.

    The aim of this study was to develop, operationalize, and pilot test a transparent, reproducible, and evidence-informed method to determine when to report incidental findings from next-generation sequencing technologies. Using evidence-based principles, we proposed a three-stage process. Stage I "rules out" incidental findings below a minimal threshold of evidence and is evaluated using inter-rater agreement and comparison with an expert-based approach. Stage II documents criteria for clinical actionability using a standardized approach to allow experts to consistently consider and recommend whether results should be routinely reported (stage III). We used expert opinion to determine the face validity of stages II and III using three case studies. We evaluated the time and effort for stages I and II. For stage I, we assessed 99 conditions and found high inter-rater agreement (89%), and strong agreement with a separate expert-based method. Case studies for familial adenomatous polyposis, hereditary hemochromatosis, and α1-antitrypsin deficiency were all recommended for routine reporting as incidental findings. The method requires definition of clinically actionable incidental findings and provide documentation and pilot testing of a feasible method that is scalable to the whole genome.

    A considerable percentage of flight crew reports to be fatigued regularly. This is partly caused by irregular and long working hours and the crossing of time zones. It has been shown that persistent fatigue can lead to health problems, impaired performance during work, and a decreased work-private life balance. It is hypothesized that an intervention consisting of tailored advice regarding exposure to daylight, optimising sleep, physical activity, and nutrition will lead to a reduction of fatigue in airline pilots compared to a control group, which receives a minimal intervention with standard available information. The study population will consist of pilots of a large airline company. All pilots who posses a smartphone or tablet, and who are not on sick leave for more than four weeks at the moment of recruitment, will be eligible for participation.In a two-armed randomised controlled trial, participants will be allocated to an intervention group that will receive the tailored advice to optimise exposure to daylight, sleep, physical activity and nutrition, and a control group that will receive standard available information. The intervention will be applied using a smartphone application and a website, and will be tailored on flight- and participant-specific characteristics. The primary outcome of the study is perceived fatigue. Secondary outcomes are need for recovery, duration and quality of sleep, dietary and physical activity behaviours, work-private life balance, general health, and sickness absence. A process evaluation will be conducted as well. Outcomes will be measured at baseline and at three and six months after baseline. This paper describes the development of an intervention for airline pilots, consisting of tailored advice (on exposure to daylight and sleep-, physical activity, and nutrition) applied into a smartphone application. Further, the paper describes the design of the randomised controlled trial evaluating the effect of the intervention on

    The main goal of this study was to present a comparison of landfill performance with respect to solids decomposition. Biochemical methane potential (BMP) test was used to determine the initial and the remaining CH(4) potentials of solid wastes during 27 months of landfilling operation in two pilot...... scale landfill reactors. The initial methane potential of solid wastes filled to the reactors was around 0.347 L/CH(4)/g dry waste, which decreased with operational time of landfill reactors to values of 0.117 and 0.154 L/CH(4)/g dry waste for leachate recirculated (R1) and non-recirculated (R2...

    The process experimental pilot plant (PREPP) incinerates mixed solid waste. The exhaust gas is processed through a wet offgas cleaning system. Rapid loading of the exhaust filters has been a problem and an important contributing factor is the use of quench solution containing a relatively high concentration of dissolved solids. The dissolved solids are released as a submicron particulate when the quench solution evaporates. A series of tests were performed to better identify the nature of the problem and explore solutions to the problem involving modifications to the quench process

    Full Text Available Key performance indicators for characterization of nanofiltration performance are well developed, similar key performance indicators for electrodialysis reversal are however underdeveloped. Under the E4Water project Dow Benelux BV and Evides Industriewater BV operate a pilot facility to compare both technologies for their application to mildly desalinate a variety of brackish water streams. Normalized pressure drop, normalized current efficiency and normalized membrane resistance proved to be a useful tool to interpret process performance and to initiate a cleaning procedure if required. The availability of these normalized key performance indicators enables optimization and process monitoring and control of electrodialysis reversal independent of the continuously changing conditions of the feed water.

    Previously reported substance abuse interventions incorporating meditation and spiritual approaches are believed to provide their benefit through modulation of both psychological and pyschosocial factors. A 90-day residential group pilot treatment program for substance abuse that incorporated a comprehensive array of yoga, meditation, spiritual and mind-body techniques was conducted in Amritsar, India. Subjects showed improvements on a number of psychological self-report questionnaires including the Behavior and Symptom Identification Scale and the Quality of Recovery Index. Application of comprehensive spiritual lifestyle interventions may prove effective in treating substance abuse, particularly in populations receptive to such approaches.

    Asthma is a common childhood chronic lung disease affecting greater than 10% of children in the United States. School nurses are in a unique position to close gaps in care. Indeed, effective asthma management is more likely to result when providers, family, and schools work together to optimize the patient's treatment plan. Currently, effective communication between schools and healthcare systems through electronic medical record (EMR) systems remains a challenge. The goal of this feasibility pilot was to link the school-based care team with primary care providers in the healthcare system network via electronic communication through the EMR, on behalf of pediatric asthma patients who had been hospitalized for an asthma exacerbation. The implementation process and the potential impact of the communication with providers on the reoccurrence of asthma exacerbations with the linked patients were evaluated. By engaging stakeholders from the school system and the healthcare system, we were able to collaboratively design a communication process and implement a pilot which demonstrated the feasibility of electronic communication between school nurses and primary care providers. Outcomes data was collected from the electronic medical record to examine the frequency of asthma exacerbations among patients with a message from their school nurse. The percent of exacerbations in the 12 months before and after electronic communication was compared using McNemar's test. The pilot system successfully established communication between the school nurse and primary care provider for 33 students who had been hospitalized for asthma and a decrease in hospital admissions was observed with students whose school nurse communicated through the EMR with the primary care provider. Findings suggest a collaborative model of care that is enhanced through electronic communication via the EMR could positively impact the health of children with asthma or other chronic illnesses.

    Full Text Available The fracture mechanical properties of silicate based materials are determined from various fracture mechanicals tests, e.g. three- or four- point bending test, wedge splitting test, modified compact tension test etc. For evaluation of the parameters, knowledge about the calibration and compliance functions is required. Therefore, in this paper, the compliance and calibration curves for a novel test geometry based on combination of the wedge splitting test and three-point bending test are introduced. These selected variants exhibit significantly various stress state conditions at the crack tip, or, more generally, in the whole specimen ligament. The calibration and compliance curves are compared and used for evaluation of the data from pilot experimental measurement.

    The US Department of Energy is planning to dispose of transuranic wastes at the Waste Isolation Pilot Plant (WIPP) near Carlsbad, New Mexico. Sandia National Laboratories is responsible for evaluating the compliance of the WIPP with the Environmental Protection Agency's Environmental Standards for the Management and Disposal of Spent Nuclear Fuel, High-Level and Transuranic Radioactive Wastes (40 CFR 191, Subpart B). This plan has been developed to present the issues that will be addressed before compliance can be evaluated. These issues examine the procedural nature of the Standard, and the technical requirements for further characterizing the behavior of the disposal system, including uncertainties, to support the compliance assessment. The plan briefly describes the activities that will be conducted prior to 1993 by Sandia to characterize the WIPP disposal system's behavior and predict its performance. 41 refs., 35 figs., 21 tabs

    To introduce and examine a pilot peer observation of teaching (POT) scheme within the Department of Paediatric Dentistry at Glasgow Dental School and its associated outreach centres. All tutors teaching paediatric dentistry were invited to be involved in evaluation of the POT scheme. Participants were randomly paired with a peer, who then observed their teaching and provided constructive feedback. For those consenting to be involved in the evaluation of the scheme, semi-structured, one-to-one interviews were carried out by the principal investigator. POT was found by all participants to be a beneficial process, reassuring those of their teaching styles and giving them ideas to adapt their teaching. POT is an effective method for engaging chair-side tutors in the reflection and development of their teaching practice via observations and scholarly discussion.

    This pilot study investigated the effectiveness of a social media literacy intervention for adolescent girls on risk factors for eating disorders. A quasi-experimental pre- to post-test design comparing intervention and control conditions was used. Participants were 101 adolescent girls (M age  = 13.13, SD = 0.33) who were allocated to receive three social media literacy intervention lessons (n = 64) or to receive classes as usual (n = 37). Self-report assessments of eating disorder risk factors were completed one week prior to, and one week following the intervention. Significant group by time interaction effects revealed improvements in the intervention condition relative to the control condition for body image (body esteem-weight; d = .19), disordered eating (dietary restraint; d = .26) and media literacy (realism scepticism; d = .32). The outcomes of this pilot study suggest that social media literacy is a potentially useful approach for prevention of risk for eating disorders in adolescent girls in the current social media environment of heightened vulnerability. Replication of this research with larger, randomized controlled trials, and longer follow-up is needed. © 2017 Wiley Periodicals, Inc.

    2017-05-25

    To develop and validate a classification of non-technical skills (NTS) in military aviation, a study was conducted, using data from real operations of F16 aircraft formations. Phase 1 developed a NTS classification based on the literature review (e.g. NOTECHS) and a workshop with pilots. The Non-TEChnical-MILitary-Skills (NOTEMILS) scheme was tested in Phase 2 in a series of Principal Component Analysis with data from After-Action-Review sessions (i.e. 900 records from a wide range of operations). The NTS were found to make a good prediction of Mission Essential Components (R 2  > 0.80) above the effect of experience. Phase 3 undertook a reliability analysis where three raters assessed the NOTEMILS scheme with good results (i.e. all r wg  > 0.80). To look into the consistency of classifications, another test indicated that, at least, two out of three raters were in agreement in over 70% of the assessed flight segments. Practitioner Summary: A classification scheme of Non-Technical Skills (NTS) was developed and tested for reliability in military aviation operations. The NTS scheme is a valuable tool for assessing individual and team skills of F-16 pilots in combat. It is noteworthy that the tool had a good capability of predicting Mission Essential Competencies.

  8. Evaluation of potential particulate/colloidal TEP foulants on a pilot scale SWRO desalination study

    2016-01-21

    This pilot study investigated the variation of potential foulants and different fractions of transparent exopolymer particles (TEP), along the treatment scheme under different conditions. The objectives are to provide a comprehensive understanding on which fraction of TEP is more problematic in seawater reverse osmosis (SWRO) fouling, and which pretreatment can better reduce the concentration of TEP. Results showed that TEP deposited on the RO membranes, and the extent of RO fouling increased with the increase of TEP concentration in RO feed water. More TEP was produced in water after chlorination, probably because of the breakdown of bacterial cells and thus the release of internal exopolymers. Moreover, the cartridge filters could behave as an incubator for the regrowth of bacteria deactivated by chlorination and a spot for potential foulant (bacterial TEP) production, and thus enhance the RO membranes fouling. The presence of residual iron and addition of phosphate based antiscalant may also contribute to the higher biofouling of RO membranes. This pilot study provided an opportunity to identify the TEP related issues under different operational conditions in RO desalination of Red Sea water.

    Clinical decision making requires 2 distinct cognitive skills: the ability to classify patients' conditions into diagnostic and management categories that permit the application of research evidence and the ability to individualize or-more specifically-to contextualize care for patients whose circumstances and needs require variation from the standard approach to care. The purpose of this study was to develop and test a methodology for measuring physicians' performance at contextualizing care and compare it to their performance at planning biomedically appropriate care. First, the authors drafted 3 cases, each with 4 variations, 3 of which are embedded with biomedical and/or contextual information that is essential to planning care. Once the cases were validated as instruments for assessing physician performance, 54 internal medicine residents were then presented with opportunities to make these preidentified biomedical or contextual errors, and data were collected on information elicitation and error making. The case validation process was successful in that, in the final iteration, the physicians who received the contextual variant of cases proposed an alternate plan of care to those who received the baseline variant 100% of the time. The subsequent piloting of these validated cases unmasked previously unmeasured differences in physician performance at contextualizing care. The findings, which reflect the performance characteristics of the study population, are presented. This pilot study demonstrates a methodology for measuring physician performance at contextualizing care and illustrates the contribution of such information to an overall assessment of physician practice.

    The 360 Degree Evaluation Model is one means to provide a comprehensive view of clinical competency and readiness for progression in an online nursing program. This pilot project aimed to evaluate the effectiveness of implementing a 360 Degree Evaluation of clinical competency of graduate advanced practice nursing students. The 360 Degree Evaluation, adapted from corporate industry, encompasses assessment of student knowledge, skills, behaviors and attitudes and validates student's progression from novice to competent. Cohort of advanced practice nursing students in four progressive clinical semesters. Graduate advanced practice nursing students (N = 54). Descriptive statistics and Jonckheere's Trend Test were used to evaluate OSCE's scores from graded rubric, standardized patient survey scores, student reflection and preceptor evaluation. We identified all students passed the four OSCEs during a first attempt or second attempt. Scaffolding OSCE's over time allowed faculty to identify cohort weakness and create subsequent learning opportunities. Standardized patients' evaluation of the students' performance in the domains of knowledge, skills and attitudes, showed high scores of 96% in all OSCEs. Students' self-reflection comments were a mix of strengths and weaknesses in their self-evaluation, demonstrating themes as students progressed. Preceptor evaluation scores revealed the largest increase in knowledge and learning skills (NONPF domain 1), from an aggregate average of 90% in the first clinical course, to an average of 95%. The 360 Degree Evaluation Model provided a comprehensive evaluation of the student and critical information for the faculty ensuring individual student and cohort data and ability to analyze cohort themes.

    Full Text Available Study Aims. Evaluate the quality and effectiveness of the medication-assisted therapy (MAT pilot in Kazakhstan and review implementation context and related challenges. Methods. We performed a desk review of MAT policy and program documents and reviewed medical records at three MAT sites in Kazakhstan. MAT patients (n=93 were interviewed to assess their perceptions of the program and its impact on their health, criminal, drug use, and HIV risk related behaviors as well as expenditures on nonprescribed psychoactive drugs. Persons injecting drugs who are not in treatment, MAT program staff, and other stakeholders were interviewed to obtain their perspectives on MAT. Results. Legislation supports introducing MAT as a standard of care for treatment of opioid dependence; however, its progress has been hampered by active opposition. Inadequate access and coverage, insufficient supply management, scarce infrastructure of narcological facilities, limited opportunities for staff development, and restrictive methadone dispensing policies compromise the quality of the intervention and limit its potential benefits. There were significant reductions in criminal, drug use, and HIV risk related behaviors in patients receiving MAT. Conclusions. The MAT pilot in Kazakhstan demonstrated its feasibility and effectiveness in the local context and is recommended for scaleup throughout the country.

    Iron and manganese originating from groundwater supplies have a long history of causing consumer complaints in water distribution systems. Although iron and manganese are not public health concerns, they are a major concern from an aesthetic standpoint. The elevated awareness of consumers in regard to the quality of drinking water, an increase in regulations requiring additional treatment and the cost associated with developing new sources of supply, has required many utilities to implement improvements to existing facilities. Historical water quality data collected from the Connecticut Water Company`s (CWC) Westbrook Well revealed an increasing trend in iron and manganese concentrations. As a result, the existing greensand filtration facility located at the well, provides insufficient removal rates and inefficient operating cycles. Variations in operating procedures were not successful in correcting these problems. A water treatment feasibility study recommended evaluation of biological and pressure clarification processes to reduce iron (9 mg/l) and manganese (1.5 mg/l) levels below the secondary maximum contaminant levels of 0.30 and 0.05 mg/l, respectively. Assessment of these processes was accomplished through the construction and operation of a 5 gallon per minute (gpm) capacity pilot plant at the Westbrook Water Treatment Plant. Application of biological treatment for iron removal was then piloted on the existing full-scale treatment facility.

    Problem-based learning (PBL) emphasizes the student's individual needs, their ability to solve complex clinical problems, and a professional attitude that facilitates communication among colleagues. Thus, PBL appears to provide a perfectly suitable didactic format for postgraduate training of medical specialties. To date, it is only rarely used in this area though. In a pilot project, we implemented PBL into the curriculum of postgraduate training in psychiatry and psychotherapy, and evaluated the program over a period of 12 months, using structured questionnaires. A total of 41 PBL courses were held, with 447 residents participating. Participants as well as tutors assessed 19 of 21 aspects as good or very good (5-point Likert scale, mean value >4). Overall, PBL was rated as highly suitable for advanced training (participants: 4.5±0.8; tutors: 5.0±0.2). The results of this pilot project suggest that PBL might be a useful element of multifaceted advanced training programs, strengthening their practical component and the applicability of knowledge in the daily clinical routine.

    Few employment programmes exist to support forensic service users with severe mental health problems and a criminal history. Little is known about how best to achieve this. The Employment and Social Inclusion Project (ESIP) was developed and piloted to support forensic service users into employment and vocational activities. This pilot service evaluation aimed to assess the number of service users who secured employment/vocational activities and explored services users' and staff experiences. Quantitative data were collected to record the characteristics of participating service users and how many secured employment and engaged in vocational activities. Eighteen qualitative interviews were conducted with service users and staff. Fifty-seven service users engaged with the project, most were men (93.0%) and previously employed (82.5%). Four service users (7.0%) secured paid competitive employment. Eight (14.0%) gained other paid employment. Tailored one-to-one support to increase skills and build confidence was an important feature of the project. Creation of a painting and decorating programme offered training and paid/flexible work. This exploratory project achieved some success in assisting forensic service users into paid employment. Further research to identify what works well for this important group will be of great value.

    Home-based palliative care is increasingly dependent on interprofessional teams to deliver collaborative care that more adequately meets the needs of clients and families. The purpose of this pilot evaluation was to qualitatively explore the views of an interprofessional group of home care providers (occupational therapists, nurses, personal support work supervisors, community care coordinators, and a team coordinator) regarding a pilot project encouraging teamwork in interprofessional palliative home care services. We used qualitative methods, informed by an interprofessional conceptual framework, to analyse participants' accounts and provide recommendations regarding strategies for interprofessional team building in palliative home health care. Findings suggest that encouraging practitioners to share past experiences and foster common goals for palliative care are important elements of team building in interprofessional palliative care. Also, establishing a team leader who emphasises sharing power among team members and addressing the need for mutual emotional support may help to maximise interprofessional teamwork in palliative home care. These findings may be used to develop and test more comprehensive efforts to promote stronger interprofessional teamwork in palliative home health care delivery.

    A pilot fish recovery system using a Hidrostal fish pump was tested in the Bruce NGS 'A' forebay during June, 1984. Despite low forebay fish concentrations, the system was capable of capturing 97,000 alewife/day (3900 kg) if operated continuously. Post-pumping survival averaged 97%. It is estimated that a single pump could handle alewife runs in the 40,000 to 70,000 kg range, but multiple pumps or a single larger pump would be required to assure station protection from the largest runs (>100,000 kg). Results indicate that tank/trailer return of pumped fish is feasible, but other alternatives for returning fish to Lake Huron are also being considered

    SummaryThe removal of selected surfactants, linear alkylbenzene sulfonates (LAS), coconut diethanol amides (CDEA) and alkylphenol ethoxylates and their degradation products were investigated using a two membrane bioreactor (MBR) with hollow fiber and plate and frame membranes. The two pilot plants MBR run in parallel to a full-scale conventional activated sludge (CAS) treatment. A total of eight influent samples with the corresponding effluent samples were analysed by solid phase extraction-liquid chromatography-tandem mass spectrometry (SPE-LC-MS-MS). The results indicate that both MBR have a better effluent quality in terms of chemical and biological oxygen demand (COD and BOD), NH4+ , concentration and total suspended solids (TSS). MBR showed a better similar performance in the overall elimination of the total nonylphenolic compounds, achieving a 75% of elimination or a 65% (the same elimination reached by CAS). LAS and CDEA showed similar elimination in the three systems investigated and no significant differences were observed.

    Citizen Science (CS) as a term implies a great deal of approaches and scopes involving many different fields of science. The number of the relevant projects globally has been increased significantly in the recent years. Large scale ecological questions can be answered only through extended observation networks and CS projects can support this effort. Although the need of such projects is apparent, an important part of scientific community cast doubt on the reliability of CS data sets. The pilot CS project COMBER has been created in order to provide evidence to answer the aforementioned question in the coastal marine biodiversity monitoring. The results of the current analysis show that a carefully designed CS project with clear hypotheses, wide participation and data sets validation, can be a valuable tool for the large scale and long term changes in marine biodiversity pattern change and therefore for relevant management and conservation issues.

    The absence of an accepted model for risk-adjustment of acute medical admissions leads to suboptimal clinical triage and serves as a disincentive to compare outcomes in different hospitals. The Simple Clinical Score (SCS) is a model based on 16 clinical parameters affecting hospital mortality. We undertook a feasibility pilot in 21 hospitals in Europe and New Zealand each collecting data for 12 or more consecutive medical emergency admissions. Data from 281 patients was analysed. Severity of illness as estimated by SCS was related to risk of admission to the Intensive Care Unit (pRisk group to 22% in the Very High Risk Group (p<0.0001). Very low scores were associated with earlier discharge as opposed to very high scores (mean length of stay of 2.4 days vs 5.6 days, p<0.001). There were differences in the pattern of discharges in different hospitals with comparable SCS data. Clinicians reported no significant problems with the collection of data for the score in a number of different health care settings. The SCS appears to be a feasible tool to assist clinical triage of medical emergency admissions. The ability to view the profile of the SCS for different clinical centres opens up the possibility of accurate comparison of outcomes across clinical centres without distortion by different regional standards of health care. This pilot study demonstrates that the adoption of the SCS is practical across an international range of hospitals. Copyright 2010 European Federation of Internal Medicine. Published by Elsevier B.V.

    Picrorhiza kurroa (Pk) is a traditional Ayurvedic herb famous as a potent hepatoprotective agent, only few studies are available on the nephroprotective activity of this herb. The objective of this pilot study was to determine the therapeutic effectiveness of Pk against nimesulide induced toxicity. Methods: This laboratory based experimental study was conducted on mice at National Institute of Health, Islamabad from Dec 2012 to Jan 2013. The mice were divided in to 4 groups. One group was given only PK while the other three groups were given nimesulide in a dosage of 750 mg/kg body weight for 3 days to induce nephrotoxicity and protective effect of Pk was noted by giving 250 mg/kg and 500 mg/kg pk for 14 days to the two of the nimesulide induced nephrotoxicity groups. Biochemical assessment of kidney was done by measuring serum urea and creatinine. Also histology was done to confirm the findings of biochemical assessment. Results: In our pilot study out of 20 mice, 19 mice survived. Only 1 mouse of nimesulide group died. Mean serum urea of nimesulide group was 60 mg/dl and was decreased to 23 mg/dl and 25 mg/dl by two doses of Pk. Mean creatinine in group 2 was 0.55 mg/dl and was decreased to 0.21 and 0.19 mg/dl by two doses of Pk. Conclusion: Our study shows that nimesulide is a potential nephrotoxic drug and its toxic effects on kidney can be minimized by using glycosidal extract of Pk. (author)

  1. A double-loop evaluation process for MOOC design and its pilot application in the university domain

    Full Text Available The diffusion of Massive Open Online Courses (MOOCs is significantly changing the way people learn and update their knowledge and competencies. Although the benefits characterizing MOOCs, which leverage on free and open access to know-how and digitized materials, there are some challenges which call for improving and enhancing the existing methods and approaches for MOOCs design. By combining theory and practice, this paper presents a process of MOOCs design based on a double-loop phase of evaluation. Specifically, the paper provides evidences on how to take advantage of the learners’ and teachers’ feedback to redesign or rethink the course’s architecture, and especially the storyboard and blueprint. A pilot application of the proposed approach has been made to design a course dealing with entrepreneurship domain, and in particular with crowdfunding. The results of the application are presented to validate the approach and provide teachers and course’s designers with some recommendations.

    This paper describes a model-predictive automatic recovery system for aircraft on the verge of a loss-of-control situation. The system determines when it must intervene to prevent an imminent accident, resulting from a poor approach. It estimates the altitude loss that would result from a go-around maneuver at the current flight condition. If the loss is projected to violate a minimum altitude threshold, the maneuver is automatically triggered. The system deactivates to allow landing once several criteria are met. Piloted flight simulator evaluation showed the system to provide effective envelope protection during extremely unsafe landing attempts. The results demonstrate how flight and propulsion control can be integrated to recover control of the vehicle automatically and prevent a potential catastrophe.

    Remediation programmes are considered to be complete when human risk-based criteria are met. However, these targets are often unsatisfied with the ecological parameters that may be important with regard to future soil use. Five soil subsamples, collecting along a pilot-scale soil column after electrokinetic treatment, were studied, from which about 42.0%-93.3% soil Cu had been successfully removed. A series of biological assays including soil microbial biomass carbon, basal soil respiration, soil urease activity, earthworm assays, and seed assays were used to evaluate their ecological risks. The results showed that the bioassay data from the treatment variants did not supposedly reflecting the decreased soil Cu concentrations after the electrokinetic treatment, but were highly correlated with some soil physicochemical characteristics. It suggests that bioassays are necessary to assess the ecotoxicity of soil after electrokinetic treatment. - There has been a motivation towards using biological indicators for risk assessment of contaminated soil after electrokinetic remediation.

    This research project evaluates post-retrofit performance measurements, energy use data and construction costs for 13 projects that participated in the National Grid Deep Energy Retrofit Pilot program. The projects implemented a package of measures defined by performance targets for building enclosure components and building enclosure air tightness. Nearly all of the homes reached a post-retrofit air tightness result of 1.5 ACH 50. Homes that used the chainsaw retrofit technique along with roof insulation, and wall insulation applied to the exterior had the best air tightness results and the lowest heating and cooling source energy use. Analysis of measure costs and project objectives yielded a categorization of costs relative to energy performance objectives. On average about 1/2 of the energy-related measure costs correspond primarily to energy-related objectives, and 20% of energy-related measure costs relate primarily to non-energy objectives.

    The sociomedical evaluation by the German Pension Insurance serves the purpose of determining entitlement to disability pensions. A quality assurance concept for the sociomedical evaluation was developed, which is based on a peer Review process. Peer review is an established process of external quality assurance in health care. The review is based on a hierarchically constructed manual that was evaluated in this pilot project. The database consists of 260 medical reports for disability pension of 12 pension insurance agencies. 771 reviews from 19 peers were included in the evaluation of the inter-rater reliability. Kendall's coefficient of concordance W for more than 2 raters is used as primary measure of inter-rater reliability. Reliability appeared to be heterogeneous. Kendalls W varies for the particular criteria from 0.09 to 0.88 and reached for primary criterion reproducibility a value of 0.37. The reliability of the manual seemed acceptable in the context of existing research data and is in line with existing peer review research outcomes. Nevertheless, the concordance is limited and requires optimisation. Starting points for improvement can be seen in a systematic training and regular user meetings of the peers involved. © Georg Thieme Verlag KG Stuttgart · New York.

    1976-01-01

    A pilot geochemical survey of the Llano, Texas, area was conducted during February and March 1976. The purpose of this work was to prepare for a subsequent reconnaissance geochemical survey of uranium in Central Texas. Stream sediment, stream water, well water, and plant ash from five geologic areas were analyzed in the laboratory for approximately 25 parameters. Examples of anomalous values in stream sediment and stream water indicate the usefulness of both sample types in identifying anomalies at a regional reconnaissance-scale station spacing of approximately 5 km (3 mi). Groundwater samples, which generally best indicate the geochemistry of formations at depth in a survey of this type, represent another important tool in detecting uranium mineralization. Anomalies in San Saba County are associated with the Marble Falls-Smithwich Formations and the Strawn Series (Pennsylvanian), the Houy Formation (Devonian and lower Mississippian), and the Hickory Sandstone Member of the Riley Formation (Cambrian). In Burnet County anomalous values are due to the influence of the Valley Spring Formation (Precambrian); and in Blanco County anomalies are found associated with the Riley Formation

    Strategies are needed to assure essential nonclinical competencies, such as leadership, can be gained using a continuing professional development (CPD) framework. The objective of this study was to explore student pharmacists' utilization and perceived effectiveness of a CPD tool for leadership development in an elective course. Students completed 2 CPD cycles during a semester-long leadership elective using a CPD tool. A questionnaire was used to measure students' perceptions of utility, self-efficacy, and satisfaction in completing CPD cycles when using a tool to aid in this process. The CPD tool was completed twice by 7 students. On average, students spent nearly 5 hours per CPD cycle. More than half (57.1%) scored themselves as successful or very successful in achieving their learning plans, and most (71.4%) found the tool somewhat useful in developing their leadership skills. Some perceived that the tool provided a systematic way to engage in leadership development, whereas others found it difficult to use. In this pilot study, most student pharmacists successfully achieved a leadership development plan and found the CPD tool useful. Providing students with more guidance may help facilitate use and effectiveness of CPD tools. There is a need to continue to develop and refine tools that assist in the CPD of pharmacy practitioners at all levels. Copyright © 2013 Elsevier Inc. All rights reserved.

    Chemotherapy-induced peripheral neuropathy (CIPN), a common side effect of chemotherapy, needs better effective treatments. Preliminary data support the use of Scrambler therapy, a device which treats pain via noninvasive cutaneous electrostimulation, for the treatment of CIPN. The current manuscript reports data from a pilot trial, performed to investigate the effect of Scrambler therapy for the treatment of established CIPN. Eligible patients had CIPN symptoms of ≥1 month duration with tingling and/or pain ≥4/10 during the prior week. Patients were treated with Scrambler therapy to the affected area(s) for up to ten daily 30-min sessions. Symptoms were monitored using a neuropathy questionnaire consisting of numerical analog scales ranging from 0 to 10, daily before therapy as well as weekly for 10 weeks after therapy. Descriptive summary statistics formed the basis of data analysis. Thirty-seven patients were enrolled. Twenty-five patients were treated primarily on their lower extremities while 12 were treated primarily on their upper extremities. There was a 53 % reduction in pain score from baseline to day 10; a 44 % reduction in tingling; and a 37 % reduction in numbness. Benefit appeared to last throughout 10 weeks of follow-up. There were no substantial adverse events. Preliminary data support that Scrambler therapy may be effective for the treatment of CIPN: a prospective placebo-controlled clinical trial should be performed.

    To characterize platelet indices at time of diagnosis of septic peritonitis in dogs and to assess the relationship between platelet parameter data and survival to discharge in dogs treated surgically. Retrospective, observational, descriptive pilot study from 2009 to 2014. University teaching hospital. Forty-eight dogs diagnosed with septic peritonitis were included in this study. Thirty-six dogs had surgical source control. Blood samples from 46 healthy control dogs were used for reference interval (RI) generation. None. Dogs with septic peritonitis had significantly increased mean values for mean platelet volume (MPV), plateletcrit (PCT), and platelet distribution width (PDW) with increased proportions of dogs having values above the RI compared to healthy dogs. A significantly increased proportion of dogs with septic peritonitis had platelet counts above (12.5%) and below (8.3%) the RI, with no significant difference in mean platelet count compared to healthy dogs. No significant differences in the mean platelet count, MPV, PCT, or PDW were found between survivors and nonsurvivors in dogs with surgical source control; however, dogs with MPV values above the RI had significantly increased mortality compared to dogs within the RI (P = 0.025). Values outside the RI for other platelet parameters were not associated with significant differences in mortality. Dogs with septic peritonitis have increased frequency of thrombocytosis and thrombocytopenia with increased MPV, PCT, and PDW. An increased MPV may be a useful indicator of increased risk of mortality in dogs treated surgically. © Veterinary Emergency and Critical Care Society 2017.

    Genetic counseling for BRCA1 and BRCA2 mutations involves teaching about hereditary cancer, genetics and risk, subjects that are difficult to grasp and are routinely misunderstood. Supported by a grant from the Avon Foundation, the UCSF Cancer Risk Program started the first genetic testing and counseling service for a population of traditionally underserved women of varied ethnic and social backgrounds at the San Francisco General Hospital (SFGH). Informed by educational theory and clinical experience, we devised and piloted two simplified explanations of heredity and genetic risk, with the aim of uncovering how to best communicate genetics and risk to this underserved population. A "conventional" version comprised pictures of genes, pedigrees, and quantitative representations of risk. A "colloquial" pictorial version used an analogy of the "information book" of genes, family stories and vignettes, and visual representations of risk, without using scientific words such as genes or chromosomes. A verbal narrative accompanied each picture. We presented these modules to four focus groups of five to eight women recruited from the SFGH Family Practice Clinic. Overall, women preferred a picture-based approach and commented that additional text would have been distracting. The majority of women preferred the colloquial version because it was easier to understand and better conveyed a sense of comfort and hope. We conclude that simplicity, analogies, and familiarity support comprehension while vignettes, family stories, and photos of real people provide comfort and hope. These elements may promote understanding of complex scientific topics in healthcare, particularly when communicating with patients who come from disadvantaged backgrounds.

    Sexual violence is a public health problem associated with short- and long-term physical and mental health consequences. Most interventions that aim to prevent sexual violence before it occurs target individual-level change or promote bystander training. Community-level interventions, while increasingly recommended in the sexual violence prevention field, are rarely documented in peer-reviewed literature. This paper is a targeted process evaluation of Project Envision, a 6-year pilot initiative to address social norms at the root of sexual violence through coalition building and community mobilization in three New York City neighborhoods, and reflects the perspectives of those charged with designing and implementing the program. Evaluation methods included a systematic literature review, archival source document review, and key informant interviews. Three themes emerged from the results: community identity and implications for engagement; capacity and readiness for community mobilization and consequences for implementation; and impacts on participants. Lessons learned include the limitations of using geographic boundaries to structure community interventions in urban settings; carefully considering whether communities should be mobilized around an externally-identified issue; translating theoretical frameworks into concrete tasks; assessing all coalition partners and organizations for readiness; critically evaluating available resources; and recognizing that community organizing is a skill that requires investment from funders. We conclude that Project Envision showed promise for shifting institutional norms towards addressing root causes of sexual violence in addition to providing victim services.

    Griswold, G.B.

    1977-12-01

    Bedded-salt deposits of the Salado Formation have been selected for evaluation for a proposed Waste Isolation Pilot Plant (WIPP) to be located in Eddy County, NM, approximately 26 mi east of Carlsbad. Site selection and evaluation studies that included geologic mapping, geophysical surveys, drilling, and resource appraisal were conducted over and under the prospective location. The lower portion of the Salado meets essential criteria for waste isolation. Beds chosen for waste storage lie 2074 to 2730 ft below the surface. High-purity salt exists at these depths, and the geologic structure revealed by geophysical surveys indicates that these beds are essentially flat. Additional geophysical surveys are now under way. The initial interpretation of the new data indicates that more structure may exist in the salt beds in the northern portion of the site area. Full evaluation of potentially commercial deposits of potash and natural gas within the WIPP site will be reported by separate studies, as will be the hydrologic details of the region

    Argueello, J.G.

    1988-04-01

    This report presents the results of a series of structural analyses performed to evaluate the structural interaction of the components of a potential two-component panel entryway seal configuration with each other and with the rock salt formation at the repository horizon of the Waste Isolation Pilot Plant. A two-dimensional axisymmetric geomechanical model is used to numerically simulate the interaction of the components of a 30.48 m (100 ft) long seal, consisting of concrete end caps and a crushed salt core, with each other and with the surrounding formation. Issues addressed in this report pertain to the consolidation of the crushed salt in terms of how much of the seal core reaches effective consolidation in the presence of the stiff concrete end caps since these could conceivably cause bridging (retardation of closure around the core) to occur. In addition, the stress field in the end caps is evaluated to determine if the concrete component maintains its integrity. The stresses induced in the surrounding formation are also evaluated to determine if the presence of the concrete component in the seal system results in a ''tightening'' of the formation around the seal. 20 refs., 43 figs., 2 tabs

    This report presents the results of field testing a horizontal well recirculation system at the Portsmouth Gaseous Diffusion Plant (PORTS). The recirculation system uses a pair of horizontal wells, one for groundwater extraction and treatment and the other for reinjection of treated groundwater, to set up a recirculation flow field. The induced flow field from the injection well to the extraction well establishes a sweeping action for the removal and treatment of groundwater contaminants. The overall purpose of this project is to study treatment of mixed groundwater contaminants that occur in a thin water-bearing zone not easily targeted by traditional vertical wells. The project involves several research elements, including treatment-process evaluation, hydrodynamic flow and transport modeling, pilot testing at an uncontaminated site, and pilot testing at a contaminated site. The results of the pilot test at an uncontaminated site, the Clean Test Site (CTS), are presented in this report

    Full Text Available Introduction: To analyze websites quality of catering companies for schools as well as their content in nutrition food education, and to have a first experience with the assessment tool EDALCAT.Material and methods: This is a descriptive cross-sectional study. The study population are the websites of catering companies entrusted with the management of school canteens. The sample was obtained using Google search engine and a ranking of major catering companies financial, choosing those that had websites. Ten websites were selected for a pilot test according to geographic proximity to the city of Alicante and their total revenue. A homemade questionnaire (EDALCAT was designed in order to evaluate the websites. This questionnaire is composed of a block of predictors of quality with 19 variables for reliability, design and navigation; and a second block of specific contents about food education with 19 variables for content and educational activities.Results: Positive results have been obtained in 31 out of 38 questionnaire variables, except for the items: “Search engine”, “Language” (40% and “Help” (10% in the predictors of the quality block; and in the items: “Workshops”, “Recipe book”, “Web nutrition-food” (40% and “Examples” (30% in the specific contents of the food education block. All the evaluated websites exceed 50% of compliance with the quality criteria and with the minimum contents in food education, and only one of them, fails the minimum level of activity established.Conclusions: The predictors of quality and the specific content in food education were successful in all evaluated websites.

    Tower fouling at petroleum refineries is related to background volatile phosphorus components originating from phosphate ester oil gellants. In an attempt to reduce the cost of unplanned refinery shut downs, the Canadian Association of Petroleum Producers (CAPP) may institute a new specification in July 2006 of 0.5 ppm maximum volatile phosphorus in crude. In concept, volatile phosphorus can be removed from phosphate esters by eliminating volatile components in the original phosphate ester gellant. However, the issue of of whether modified phosphate esters can really reduce refinery tower fouling has been questioned. For that reason, this study focused on water hydrolysis which may occur in a distillation tower, causing localized areas of acidity and causticity. Halogenation reactions could occur in the presence of acid at high temperatures if halogen ions are present. The source of halide ions could be any salts that have not been removed in the de-salters. Full-scale testing at a pilot plant facility was conducted over several days with flowback captured after actual fracturing treatments. Fouling of distillation tower trays was measured along with fouling of the packing material. The study examined how fouling was influenced by changes in operating parameters such as rate, temperature, or pressure during each test. Three full-scale pilot evaluations were conducted using actual flowback fluids from fracturing treatments conducted with 3 different oil gellants: conventional phosphate ester, modified phosphate and phosphonate ester. The comparison of actual tower fouling between these alternative gellants can be used as a guide when choosing oil gellant systems to reduce refinery tower and heat exchanger fouling. It was concluded that phosphonate gellants are hydrolytically stable at higher temperatures and should minimize volatile phosphorus created through the hydrolysis of phosphate esters. However, they are more expensive since they are more complex to create

    Full Text Available Intuitively, wildlife crossing structures should enhance the viability of wildlife populations. Previous research has demonstrated that a broad range of species will use crossing structures, however, questions remain as to whether these measures actually provide benefits to populations. To assess this, studies will need to determine the number of individuals using crossings, their sex, and their genetic relationships. Obtaining empirical data demonstrating population-level benefits for some species can be problematic and challenging at best. Molecular techniques now make it possible to identify species, individuals, their sex, and their genetic relatedness from hair samples collected through non-invasive genetic sampling (NGS. We describe efforts to pilot a method to assess potential population-level benefits of wildlife crossing structures. We tested the feasibility of a prototype NGS system designed to sample hair from black bears (Ursus americanus and grizzly bears (U. arctos at two wildlife underpasses. The piloted hair-sampling method did not deter animal use of the trial underpasses and was effective at sampling hair from more than 90% of the bear crossing events at the underpasses. Hair samples were also obtained from non-target carnivore species, including three out of five (60% cougar (Puma concolor crossing events. Individual identification analysis revealed that three female and two male grizzly bears used one wildlife underpass, whereas two female and three male black bears were identified as using the other underpass. Of the 36 hair samples from bears analyzed, five failed, resulting in an 87% extraction success rate, and six more were only identified to species. Overall, 70% of the hair samples from bears collected in the field had sufficient DNA for extraction purposes. Preliminary data from our NGS suggest the technique can be a reliable method to assess the population-level benefits of Banff wildlife crossings. Furthermore, NGS

    High rates of mental illness and addictions are well documented among youth in Nicaragua. Limited mental health services, poor mental health knowledge and stigma reduce help-seeking. The Mental Health Curriculum (MHC) is a Canadian school-based program that has shown a positive impact on such contributing factors. This pilot project evaluated the impact of the MHC on mental wellness and functioning among youth in Leon, Nicaragua. High school and university students (aged 14-25 years) were assigned to intervention (12-week MHC; n   =  567) and control (wait-list; n   =  346) groups in a non-randomized design. Both groups completed measures of mental health knowledge, stigma and function at baseline and 12 weeks. Multivariate analyses and repeated measures analyses were used to compare group outcomes. At baseline, intervention students showed higher substance use (mean difference [MD]  =  0.24) and lower perceived stress (MD = -1.36) than controls ( p   mental health knowledge (MD  =  1.75), lower stigma (MD  =  1.78), more adaptive coping (MD  =  0.82), better lifestyle choices (MD  =  0.06) and lower perceived stress (MD = -1.63) ( p   mental health knowledge, small to moderate for stigma and modest for the other variables. Substance use also decreased among intervention students to similar levels as controls (MD  =  0.03) ( p  > 0.05). This pilot investigation demonstrates the benefits of the MHC in a low-and-middle-income youth population. The findings replicate results found in Canadian student populations and support its cross-cultural applicability.

    Develop and pilot an Internet-facilitated cognitive-behavioral treatment intervention for depression, tailored to economically disadvantaged mothers of young children. Mothers (N = 70) of children enrolled in Head Start, who reported elevated levels of depressive symptoms, were randomized to either the 8-session, Internet-facilitated intervention (Mom-Net) or delayed intervention/facilitated treatment-as-usual (DI/TAU). Outcomes were measured using the Beck Depression Inventory (BDI-II; Beck, Steer, & Brown, 1996); the Patient Health Questionnaire 9 (PHQ-9; Spitzer et al., 1999), Behavioral Observations of Parent-Child Interactions using the Living in Family Environments coding system (LIFE; Hops, Davis, & Longoria, 1995); the Dyadic Parent-Child Interaction Coding Systems (DPICS; Eyberg, Nelson, Duke, & Boggs, 2005); the Parent Behavior Inventory (PBI; Lovejoy, Weis, O'Hare, & Rubin, 1999); and the Parenting Sense of Competence scale (PSOC; Gibaud-Wallston & Wandersman, 1978). Mom-Net demonstrated high levels of feasibility as indicated by low attrition and high program usage and satisfaction ratings. Participants in the Mom-Net condition demonstrated significantly greater reduction in depression, the primary outcome, at the level of both symptoms and estimates of criteria-based diagnoses over the course of the intervention. They also demonstrated significantly greater improvement on a questionnaire measure of parent satisfaction and efficacy as well as on both questionnaire and observational indices of harsh parenting behavior. Initial results suggest that the Mom-Net intervention is feasible and efficacious as a remotely delivered intervention for economically disadvantaged mothers.

Activation of the enzyme telomerase can add telomeric DNA to retinal pigment epithelium chromosomal ends and has been proposed as a treatment for age-related macular degeneration. We report the use of a small molecule, oral telomerase activator (TA-65 in early macular degeneration. This study, focusing on early macular degeneration, provides a model for the use of TAs in age-related disease.Method: Thirty-eight (38 patients were randomly assigned to a 1-year, double-blinded, placebo-controlled interventional study with arms for oral TA-65 or placebo. Macular functions via micro-perimetry were the primary measured outcomes.Results: The macular function in the arm receiving the TA-65 showed significant improvement relative to the placebo control. The improvement was manifest at 6 months and was maintained at 1 year: macular threshold sensitivity (measured as average dB [logarithmic decibel scale of light attenuation] improved 0.97 dB compared to placebo (P-value 0.02 and percent reduced thresholds lessened 8.2% compared to the placebo arm (P-value 0.04. Conclusion: The oral TA significantly improved the macular function of treatment subjects compared to controls. Although this study was a pilot and a larger study is being planned, it is noteworthy in that it is, to our knowledge, the first randomized placebo-controlled study of a TA supplement.

    Full Text Available Background: Antibiotics are considered among the most commonly prescribed drug classes in developing countries. Inappropriate prescription of antibiotics is a major public health concern and is related to the development of antimicrobial resistance. Objective: This study aimed at assessing the appropriateness of antibiotic prescription by non-infectious disease physicians in a community setting in Lebanon. Methods: A pilot cross-sectional study was undertaken on community pharmacy patients presenting with antibiotic prescription. It was performed over a period of 4 months in different regions of Lebanon. Participants answered a questionnaire inquiring about socio-demographic characteristics, medical conditions, symptoms that required medical attention, the doctor's diagnosis, the prescribed antibiotic, and whether laboratory tests were ordered to identify the causative organism or not. Data were analyzed using SPSS 17. Results: We studied 270 patients (49.3% males and 50.7% females. This study showed that the most-prescribed antibiotics were the cephalosporins (82% and that almost half of the illnesses for which antibiotics were prescribed were respiratory tract infections (41%. The study also showed that the choice of the prescribed antibiotic was appropriate in 61.5% of the studied cases, while the prescribed dose and the duration of the treatment were inaccurate in 52 and 64% of the cases, respectively. In addition, fever seemed to be a factor that influenced the physician's prescriptions, since the choice of drug conformity to guidelines increased from 53.7% (1 day of fever to 88.9% (1 week of fever, and the dose prescription compliance to guidelines was higher (55.9% for patients suffering from fever compared to those with no fever (38.1%. Conclusion: This study showed a high prevalence of inappropriate antibiotic prescriptions in Lebanon. Therefore, actions should be taken to optimize antibiotic prescription.

    Concept mapping, as a teaching strategy, has been shown to promote critical thinking and problem solving in educational settings. Dental clinicians must distinguish between critical and irrelevant characteristics in the delivery of care, thus necessitating reasoning skills to do so. One of the aims of the American Dental Education Association Commission on Change and Innovation (ADEA-CCI) is to identify deficiencies in curriculum which were meant to improve critical thinking and problem solving skills necessary in clinical practice. The purpose of this study was to compare 2 teaching strategies, traditional lecture and lecture supported by concept mapping exercises within collaborative working groups, to determine if there is a beneficial effect on meaningful learning. For this pilot study, the study population consisted of students from 2 geographically separated associate level dental hygiene programs in the southeastern U.S. A quasi-experimental control group pre- and post-test design was used. The degree of meaningful learning achieved by both programs was assessed by comparing pre- and post-test results. Both programs experienced a significant degree of meaningful learning from pre- to post-test. However, there was no statistically significant difference between the programs on the post-test. These results were in direct contrast to research in other disciplines on concept mapping and its effect on promoting meaningful learning. Further investigation into the study's outcome was obtained through a follow-up focus group. In spite of careful attention to methodology in the development of this research project, the focus group illuminated methodological failings that potentially impacted the outcome of the study. Recommendations are underscored for future conduct of educational research of this kind.

    Host modulation is fast gaining popularity as a preferred therapeutic modality for periodontal disease. Recent research in the medical field into herbal immunomodulators such as Septilin® has spurred an interest in evaluating its efficacy in periodontitis for the first time. The aim of the study was to assess the immunomodulatory effects of the herbal immunomodulator Septilin® (Himalaya Drug Company, Bangalore, India) when used as an adjunct to scaling and root planing in chronic periodontal disease. Forty systemically healthy patients aged between 25 and 55 years of age and with chronic periodontitis were randomly divided into two groups. The test group was administered Septilin® tablets for two weeks following scaling and root planing whereas the control group was treated by scaling and root planing alone. Changes in gingival index (GI), gingival bleeding index (GBI), serum C-reactive protein (CRP) levels and salivary tumour necrosis factor-alpha (TNF-α) levels were assessed at day 0, at two weeks, and at three and six months. The GI and GBI showed a statistically significant reduction at two weeks, three months and six months (P0.05). In this pilot evaluation, Septilin® was found to be a safe and effective immunomodulator as an adjunct to routine periodontal therapy. Further long-term studies to test Septilin® on larger sections of the population are recommended.

    The objective of this study was to evaluate the efficacy of lung cancer screening by thoracic computed tomography (CT), a randomized controlled trial was planned in Japan. The randomized trial was designed as follows: participants were randomly assigned into 2 groups, CT group and XP group; XP group would receive 10 times of lung cancer screening by chest x-ray annually for 10 years; smokers in CT group would receive 10 times of lung cancer screening by thoracic CT annually for 10 years; non-smokers in CT group would receive 3 times of lung cancer screening by thoracic CT and 7 times of chest x-ray during 10 years. A pilot study was performed to evaluate the feasibility of the trial. A letter for recruitment to participate in the above trial was mailed to the citizens in Hakui City, who were 50-64 years old and underwent regular lung cancer screening using chest x-ray this year. In the letter we explained that the efficacy of lung cancer screening by thoracic CT had not been proved yet; only half of the participants could undergo thoracic CT screening; thoracic CT screening might cause unfavorable consequences like radiation exposure, false positives or overdiagnosis. Of 329 persons who received the letter of recruitment, 117 replied. After meeting with us for detailed explanation, 111 persons participated in the above randomized trial. The compliance of recruitment is high (approximately one third) and the above trial may be feasible. (author)

    This pilot study is the starting point of a potentially broad research project aimed at identifying new strategies for assessing malingering during forensic evaluations. The forensic group was comprised of 67 males who were seeking some sort of certification (e.g., adoption, child custody, driver's license, issuance of gun permits, etc.); the nonforensic group was comprised of 62 healthy male volunteers. Each participant was administered the MMPI-2. Statistical analyses were conducted on obtained scores of 48 MMPI-2 scales. In the first step, parametric statistics were adopted to identify the best combination of MMPI-2 scales that differentiated the two groups of participants. In the second step, frequency-based, nonparametric methods were used for diagnostic purposes. A model that utilized the best three predictors ("7-Pt", "L," and "1-Hs") was developed and used to calculate the Forensic Evaluation Dissimulation Index (FEDI), which features satisfactory diagnostic accuracy (0.9), sensitivity (0.82), specificity (0.81), and likelihood ratio indices (LR+ = 4.32; LR- = 0.22). © 2015 American Academy of Forensic Sciences.

    The Italian National Health System (NHS), established in 1978, follows a model similar to the Beveridge model developed by the British NHS (Beveridge 1942; Musgrove 2000). Like the British NHS, healthcare coverage for the Italian population is provided and financed by the government through taxes. Universal coverage provides uniform healthcare access to citizens and is the characteristic usually considered the added value of a welfare system financed by tax revenues. Nonetheless, in Italy the strong policy of decentralization, which has been taking place since the early 1990s, has gradually shifted powers from the state to the 21 Italian regions. Consequently, the state now retains limited supervisory control and continues to have overall responsibility for the NHS in order to ensure uniform and essential levels of health services across the country. In this context, it has become essential, both for the ministry and for regions, to adopt a common performance evaluation system (PES). This article reports the definition, implementation, and first evidences of a pilot PES at a national level. It shows how this PES can be viewed as a strategic tool supporting the Ministry of Health (MoH) in ensuring uniform levels of care for the population and assisting regional managers to evaluate performance in benchmarking. Finally, lessons for other health systems, based on the Italian experience, are provided.

    Providing timely palliative and end-of-life care (PC/EOL) information to parents of children with a serious illness is a national health care priority. The goals of this study were to determine feasibility, acceptability, and parent responses related to a PC/EOL communication intervention, titled "Communication Plan: Early through End of Life (COMPLETE)" to parents of children with a brain tumor. The study was a 2-site prospective, single-group pilot study targeting parents' stress and coping outcomes. The sample included 13 parents of 11 children (ie, 11 families). During the first 6 months postdiagnosis, we evaluated parent outcomes at 4 time points (baseline and 3 post-sessions). Our findings included significant decline in decision regret ( P = .0089); strong, significantly increased hope ( P ≤ .0001); and significantly decreased uncertainty ( P = .04). Over time, more than half of the parents (61.5%) preferred to receive information about their child's current condition and PC/EOL options. Our findings provide evidence to suggest that the COMPLETE intervention is feasible and acceptable and produces promising effects on 3 parent outcomes (ie, decision regret, hope, and uncertainty) in parents of children with a brain tumor. Further research is indicated to evaluate COMPLETE with a larger sample of parents of children with cancer and with a control group.

    Conventional approaches to participant recruitment are often inadequate in rare disease investigation. Social networking sites such as Facebook may provide a vehicle to circumvent common research limitations and pitfalls. We report our preliminary experience with Facebook-based methodology for participant recruitment and participation into an ongoing study of autoimmune hepatitis (AIH). The goal of our research was to conduct a pilot study to assess whether a Facebook-based methodology is capable of recruiting geographically widespread participants into AIH patient-oriented research and obtaining quality phenotypic data. We established a Facebook community, the Autoimmune Hepatitis Research Network (AHRN), in 2014 to provide a secure and reputable distillation of current literature and AIH research opportunities. Quarterly advertisements for our ongoing observational AIH study were posted on the AHRN over 2 years. Interested and self-reported AIH participants were subsequently enrolled after review of study materials and completion of an informed consent by our study coordinator. Participants returned completed study materials, including epidemiologic questionnaires and genetic material, to our facility via mail. Outside medical records were obtained and reviewed by a study physician. We successfully obtained all study materials from 29 participants with self-reported AIH within 2 years from 20 different states. Liver biopsy results were available for 90% (26/29) of participants, of which 81% (21/29) had findings consistent with AIH, 15% (4/29) were suggestive of AIH with features of primary biliary cholangitis (PBC), and 4% (1/29) had PBC alone. A total of 83% (24/29) had at least 2 of 3 proposed criteria: positive autoimmune markers, consistent histologic findings of AIH on liver biopsy, and reported treatment with immunosuppressant medications. Self-reported and physician records were discrepant for immunosuppressant medications or for AIH/PBC diagnoses in 4

    To evaluate the applicability of magnetic resonance imaging (MRI) as a method for monitoring the activity of otospongiotic lesions before and after clinical treatment. Prospective, randomized, controlled, double-blind study. One single tertiary care institution in a large, cosmopolitan city. Twenty-six patients (n = 42 ears) with clinical, audiometric, and tomographic diagnosis of otosclerosis were enrolled. If computed tomography (CT) demonstrated active lesions, these patients underwent MRI to detect otospongiotic foci, seen as areas of gadolinium enhancement. Patients were divided into 3 groups and received treatment with placebo, sodium alendronate, or sodium fluoride for 6 months. After this period, clinical and audiometric evaluations and a second MRI were performed. Each MRI was evaluated by both a neuroradiologist and an otolaryngologist in a subjective (visual) and objective (using specific eFilm Workstation software) manner. Otospongiosis was most predominantly identified in the region anterior to the oval window, and this site was reliable for comparing pre- and posttreatment scans. The patients in the alendronate and sodium fluoride groups had MRI findings that suggested a decrease in activity of otospongiotic lesions, more relevant in the alendronate group. These findings were statistically significant for both subjective and objective MRI evaluations. MRI shows higher sensitivity than clinical or audiometric assessment for detecting reduction in activity of otospongiosis. The objective MRI evaluation based on software analysis was the most accurate method of monitoring clinical treatment response in otospongiosis. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2015.

    Case investigation and reactive case detection (RACD) activities are widely-used in low transmission settings to determine the suspected origin of infection and identify and treat malaria infections nearby to the index patient household. Case investigation and RACD activities are time and resource intensive, include methodologies that vary across eliminating settings, and have no standardized metrics or tools available to monitor and evaluate them. In response to this gap, a simple programme tool was developed for monitoring and evaluating (M&E) RACD activities and piloted by national malaria programmes. During the development phase, four modules of the RACD M&E tool were created to assess and evaluate key case investigation and RACD activities and costs. A pilot phase was then carried out by programme implementers between 2013 and 2015, during which malaria surveillance teams in three different settings (China, Indonesia, Thailand) piloted the tool over a period of 3 months each. This study describes summary results of the pilots and feasibility and impact of the tool on programmes. All three study areas implemented the RACD M&E tool modules, and pilot users reported the tool and evaluation process were helpful to identify gaps in RACD programme activities. In the 45 health facilities evaluated, 71.8% (97/135; min 35.3-max 100.0%) of the proper notification and reporting forms and 20.0% (27/135; min 0.0-max 100.0%) of standard operating procedures (SOPs) were available to support malaria elimination activities. The tool highlighted gaps in reporting key data indicators on the completeness for malaria case reporting (98.8%; min 93.3-max 100.0%), case investigations (65.6%; min 61.8-max 78.4%) and RACD activities (70.0%; min 64.7-max 100.0%). Evaluation of the SOPs showed that knowledge and practices of malaria personnel varied within and between study areas. Average monthly costs for conducting case investigation and RACD activities showed variation between study

    To compare MR perfusion imaging with perfusion scintigraphy in the evaluation of patients with pulmonary emphysema being considered for lung volume reduction surgery. Six patients with pulmonary emphysema and two normal individuals were evaluated by MR perfusion imaging, perfusion scintigraphy, and selective bilateral pulmonary angiography. MR images were obtained with an enhanced fast gradient recalled echo with three-dimensional Fourier transformation technique (efgre 3D) (6.3/1.3; flip angle, 30 deg C; field of view, 45-48 cm; matrix, 256 x 160). The presence or absence of perfusion defects in each segment was evaluated by two independent observers. Using angiography as the gold standard, the sensitivity, specificity, and accuracy of MR perfusion imaging in detecting focal perfusion abnormalities were 90%, 87%, and 89%, respectively, while those of perfusion scintigraphy were 71%, 76%, and 71%, respectively. The diagnostic accuracy of MR perfusion imaging was significantly higher than that of scintigraphy (p<0.001, McNemar test). There was good agreement between two observers for MR perfusion imaging (kappa statistic, 0.66) and only moderate agreement for perfusion scintigraphy (kappa statistic, 0.51). MR perfusion imaging is superior to perfusion scintigraphy in the evaluation of pulmonary parenchymal perfusion in patients with pulmonary emphysema. (author)

    Alcohol screening, brief intervention, and referral to treatment (SBIRT) is a set of clinical strategies for reducing the burden of alcohol-related injury, disease, and disability. SBIRT is typically considered a physician responsibility but calls for interdisciplinary involvement requiring basic SBIRT knowledge and skills training for all healthcare disciplines. The purpose of this pilot study was to design, implement, and evaluate a theory-driven SBIRT training program for nurses in inpatient settings (RN-SBIRT) that was developed through an interdisciplinary collaboration of nursing, medical, and public health professionals and tailored for registered nurses in the inpatient setting. In this three-phase study, we evaluated (1) RN-SBIRT's effectiveness for changing nurses' alcohol-related knowledge, clinical practice, and attitudes and (2) the feasibility of implementing the inpatient curriculum. In a quasi-experimental design, two general medical units at our facility were randomized to receive RN-SBIRT or a self-directed Web site on alcohol-related care. We performed a formative evaluation of RN-SBIRT, guided by the RE-AIM implementation framework. After training, nurses in the experimental condition had significant increases in Role Adequacy for working with drinkers and reported increased performance and increased competence for a greater number of SBIRT care tasks. Despite some scheduling challenges for the nurses to attend RN-SBIRT, nurse stakeholders were highly satisfied with RN-SBIRT. Results suggest that with adequate training and ongoing role support, nurses in inpatient settings could play active roles in interdisciplinary initiatives to address unhealthy alcohol use among hospitalized patients.

    Purpose: We have instigated a phase I trial of 5-fraction stereotactic body radiotherapy (SBRT) for advanced-stage laryngeal cancer. We conducted this pilot dosimetric study to confirm the potential utility of online adaptive re-planning to preserve treatment quality. Methods: Ten cases of larynx cancer were evaluated. Baseline and daily SBRT treatment plans were generated per trial protocol. Daily volumetric images were acquired prior to every fraction of treatment. Reference simulation CT images were deformably registered to daily volumetric images using Eclipse. Planning contours were then deformably propagated to daily images. Reference SBRT plans were directly copied to calculate delivered dose distributions on deformed reference CT images. In-house software platform has been developed to calculate cumulative dose over a course of treatment in four steps: 1) deforming delivered dose grid to reference CT images using deformation information exported from Eclipse; 2) generating tetrahedrons using deformed dose grid as vertices; 3) resampling dose to a high resolution within every tetrahedron; 4) calculating dose-volume histograms. Our inhouse software was benchmarked with a commercial software, Mirada. Results: In all ten cases including 49 fractions of treatments, delivered daily doses were completely evaluated and treatment could be re-planned within 10 minutes. Prescription dose coverage of PTV was less than intended in 53% of fractions of treatment (mean: 94%, range: 84%–98%) while minimum coverage of CTV and GTV was 94% and 97%, respectively. Maximum bystander point dose limits to arytenoids, parotids, and spinal cord remained respected in all cases, although variances in carotid artery doses were observed in a minority of cases. Conclusion: Although GTV and CTV coverage is preserved by in-room 3D image guidance of larynx SBRT, PTV coverage can vary significantly from intended plans. Online adaptive treatment evaluation and re-planning is potentially

    Purpose: Transgender individuals (TGI), who identify their gender as different from their sex assigned at birth, continue facing widespread discrimination and mistreatment within the healthcare system. Providers often lack expertise in adequate transgender (TG) care due to limited specialized training. In response to these inadequacies, and to increase evidence-based interventions effecting TG-affirmative healthcare, we implemented and evaluated a structural-level intervention in the form of a comprehensive Provider Training Program (PTP) in TG health within a New York City-based outpatient clinic serving primarily individuals of color and of low socioeconomic status. This pilot intervention aimed to increase medical staff knowledge of TG health and needs, and to support positive attitudes toward TGI. Methods: Three 2-h training sessions were delivered to 35 clinic staff across 4 months by two of the authors experienced in TG competency training; the training sessions included TG-related identity and barriers to healthcare issues, TG-specialized care, and creating TG-affirmative environments, medical forms, and billing procedures. We evaluated changes through pre-post intervention surveys by trainees. Results: Compared to pre-training scores, post-training scores indicated significant (1) decreases in negative attitudes toward TGI and increases in TG-related clinical skills, (2) increases in staff's awareness of transphobic practices, and (3) increases in self-reported readiness to serve TGI. The clinic increased its representation of general LGBT-related images in the waiting areas, and the staff provided highly positive training evaluations. Conclusion: This PTP in TG health shows promise in leading to changes in provider attitudes and competence, as well as clinic systems, especially with its incorporation in continuing education endeavors, which can, in turn, contribute to health disparities reductions among TG groups.

    12-lead ECG is a critical component of initial evaluation of cardiac ischemia, but has traditionally been limited to large, dedicated equipment in medical care environments. Smartphones provide a potential alternative platform for the extension of ECG to new care settings and to improve timeliness of care. To gain experience with smartphone electrocardiography prior to designing a larger multicenter study evaluating standard 12-lead ECG compared to smartphone ECG. 6 patients for whom the hospital STEMI protocol was activated were evaluated with traditional 12-lead ECG followed immediately by a smartphone ECG using right (VnR) and left (VnL) limb leads for precordial grounding. The AliveCor™ Heart Monitor was utilized for this study. All tracings were taken prior to catheterization or immediately after revascularization while still in the catheterization laboratory. The smartphone ECG had excellent correlation with the gold standard 12-lead ECG in all patients. Four out of six tracings were judged to meet STEMI criteria on both modalities as determined by three experienced cardiologists, and in the remaining two, consensus indicated a non-STEMI ECG diagnosis. No significant difference was noted between VnR and VnL. Smartphone based electrocardiography is a promising, developing technology intended to increase availability and speed of electrocardiographic evaluation. This study confirmed the potential of a smartphone ECG for evaluation of acute ischemia and the feasibility of studying this technology further to define the diagnostic accuracy, limitations and appropriate use of this new technology.

    The latest generation of radiofrequency, nanofractional radiofrequency, allows the heat energy to be delivered through the use of pins or needles as electrodes, facilitating increased efficacy and reduced pain, downtime, and side effects. The objective of this prospective pilot clinical study was to evaluate the efficacy of nanofractional radiofrequency in skin resurfacing. Seventeen subjects were enrolled in the study, and each received three nanofractional radiofrequency (160-pin tip) treatments in the facial area at 3-week intervals. Follow-up visits were scheduled at 1 and 2 months after the final treatment. Clinical photography, patient, and investigator assessments were conducted during the treatment visits and follow-up. All subjects completed the study. At the 1- and 2-month follow-up, there was a moderate to significant improvement (2.6 and 3.5, respectively, P = .01) according to the investigator global esthetic improvement scale rating. Most subjects reported that they were satisfied or very satisfied with the outcome and level of comfort. Nanofractional radiofrequency is a safe and effective strategy for improving texture, tone, and skin laxity with high patient satisfaction and tolerable safety profile. © 2017 Wiley Periodicals, Inc.

    The present pilot study evaluates the histopathological characteristics and suitability of CO2 and diode lasers for performing excisional biopsies in the buccal mucosa with special emphasis on the extent of the thermal damage zone created. 15 patients agreed to undergo surgical removal of their fibrous hyperplasias with a laser. These patients were randomly assigned to one diode or two CO2 laser groups. The CO2 laser was used in a continuous wave mode (cw) with a power of 5 W (Watts), and in a pulsed char-free mode (cf). Power settings for the diode laser were 5.12 W in a pulsed mode. The thermal damage zone of the three lasers and intraoperative and postoperative complications were assessed and compared. The collateral thermal damage zone on the borders of the excisional biopsies was significantly smaller with the CO, laser for both settings tested compared to the diode laser regarding values in pm or histopathological index scores. The only intraoperative complication encountered was bleeding, which had to be controlled with electrocauterization. No postoperative complications occurred in any of the three groups. The CO2 laser seems to be appropriate for excisional biopsies of benign oral mucosal lesions. The CO2 laser offers clear advantages in terms of smaller thermal damage zones over the diode laser. More study participants are needed to demonstrate potential differences between the two different CO2 laser settings tested.

  11. Beat the Street: A Pilot Evaluation of a Community-Wide Gamification-Based Physical Activity Intervention.

    Harris, Marc Ashley

    2018-04-19

    There is a plethora of published research reporting the wealth and breadth of biopsychosocial benefits of physical activity; however, a recent Cochrane systematic review concluded insufficient evidence for current population level physical activity interventions, citing scalability as a major contributory factor, with many of the interventions failing to reach a substantial proportion of the community. The current study aimed to conduct a pilot evaluation of a technology-enabled, gamification-based intervention called Beat the Street and sought to examine the impact of the Beat the Street intervention on self-reported physical activity. In total, n = 329 people completed the International Physical Activity Questionnaire Short Form (I-PAQ-SF) in full at baseline (before the intervention) and follow-up (immediately following the 7-week intervention). Overall, participants increased their weekly walking by +180 minutes per week (P < 0.001) and their weekly physical activity by +335 minutes per week (P < 0001). Vigorous activity increased by +48 minutes per week (P = 0.004) and moderate activity increased by +60 minutes per week (P < 0.001). The findings provide preliminary evidence that the Beat the Street intervention may be a promising approach to increasing physical activity at a community-wide level and warrants further investigation.

    Beat the Street aims to get children more active by encouraging them to walk and cycle in their neighbourhood using tracking technology with a reward scheme. This pilot study evaluates the impact of Beat the Street on active travel to school in Norwich, UK. Eighty children 8-10 yrs were recruited via an intervention and control school. They wore an accelerometer for 7 days at baseline, mid-intervention and post-intervention (+20 weeks), and completed a travel diary. Physical activity overall was not higher at follow-up amongst intervention children compared to controls. However, there was a positive association between moderate-to-vigorous physical activity (MVPA) during school commute times and the number of days on which children touched a Beat the Street sensor. This equated to 3.46min extra daily MVPA during commute times for children who touched a sensor on 14.5 days (the mean number of days), compared to those who did not engage. We also found weekly active travel increased at the intervention school (+10.0% per child) while it decreased at the control (-7.0%), p=0.056. Further work is needed to understand how improved engagement with the intervention might impact outcomes. Copyright © 2016 The Authors. Published by Elsevier Ltd.. All rights reserved.

    2017-08-01

    Low-income and minority children are susceptible to obesity due to the social and environmental barriers that influence their health behaviors. Many programs and interventions fail to account for these aforementioned barriers among this population. Given what we know about the complexity of childhood obesity, low-income and minority children require innovative prevention strategies from those used in traditional childhood obesity interventions. The purpose of this study was to describe the evaluation of a 6-week summer childhood obesity pilot intervention designed for low-income and minority children. Focus groups and interviews (N = 29) were conducted among caregivers. Overall, caregivers indicated that the experience was mostly positive for their children who obtained small amounts of knowledge and behavioral changes. Caregivers also noted several perceived barriers for intervention completion. The CHOICES intervention is a promising approach that warrants attention in future childhood obesity intervention design. Interventions involving low-income and minority children should aim to help participants make healthier choices given the environmental and social barriers that cannot be overlooked or changed.

    The objective of this research was to conduct a performance evaluation of three food waste/biowaste-to-biogas pilot projects across 7 scenarios in China based on multi-criteria decision analysis (MCDA) methodology. The projects ranked included a food waste-biogas project in Beijing, a food waste-biogas project in Suzhou and a co-digestion project producing biomethane in Hainan. The projects were ranked from best to worst based on technical, economic and environmental criteria under the MCDA framework. The results demonstrated that some projects are encountering operational problems. Based on these findings, six national policy recommendations were provided: (1) shift away from capital investment subsidies to performance-based subsidies; (2) re-design feed in tariffs; (3) promote bio-methane and project clustering; (4) improve collection efficiency by incentivizing FW producers to direct waste to biogas projects; (5) incentivize biogas projects to produce multiple outputs; (6) incentivize food waste-based projects to co-digest food waste with other substrates for higher gas output.

    The pain and anxiety associated with vaccination is a significant reason why parents are reluctant to have their children vaccinated. Distraction methods and vapocoolant sprays may be use to modify the parent's perceptions of their child's pain and anxiety, thus encouraging parents to return for the child's next vaccination. A convenience sample of 68 parents with children ranging in age from 2 to 12 years was selected. The parents and the child were randomly assigned to three groups: a control group, a DVD distraction group, or a vapocoolant spray group. After the child was vaccinated, parents evaluated the child's pain and anxiety. No significant difference in the parents' perception of their child's pain or anxiety was found between the two treatment groups compared with the control group. Some parents expressed the desire to be able to choose the type of distraction method their child received rather than having them randomly assigned to a group. Although quantitative results were not statistically significant in this pilot study, parents commented that the DVD distraction method seemed helpful before and/or after vaccination, but not during vaccination, and parents appreciated the distraction. Parents, however, would prefer to choose the intervention rather than being randomly assigned to a group. The effectiveness of interventions with regard to parental perceptions of pain or anxiety warrants further study. Copyright © 2013 National Association of Pediatric Nurse Practitioners.

    Mechanical ventilation is one of the most important therapeutic interventions in neonatal and pediatric ICUs. Telemedicine has been shown to reliably extend pediatric intensivist expertise to facilities where expertise is limited. If reliable, telemedicine may extend the reach of pediatric respiratory therapists (RTs) to facilities where expertise does not exist or free up existing RT resources for important face-to-face activities in facilities where expertise is limited. The aim of this study was to determine how well respiratory assessments for ventilated neonates and children correlated when performed simultaneously by 2 RTs face-to-face and via telemedicine. We conducted a pilot study including 40 assessments by 16 RTs on 11 subjects (5 neonatal ICU; 6 pediatric ICU). Anonymously completed intake forms by 2 different RTs concurrently assessing 14 ventilator-derived and patient-based respiratory variables were used to determine correlations. Forty paired assessments were performed. Median telemedicine assessment time was 8 min. The Pearson correlation coefficient (r) was used to determine agreement between continuous data, and the Cohen kappa statistics were used for binary variables. Pressure control, PEEP, breathing frequency, and FIO2 perfectly correlated (r = 1, all P Telemedicine technology was acceptable to RTs. Telemedicine evaluations highly correlated with face-to-face for 10 of 14 aspects of standard bedside respiratory assessment. Poor correlation was noted for more complex, patient-generated parameters, highlighting the importance of further investigation incorporating a virtual stethoscope.

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

    High attrition rates hint at deficiencies in the resident selection process. The evaluation of personal characteristics representative of success is difficult. Here, we evaluate a novel tool for assessing personal characteristics. To evaluate feasibility, we used an anonymous voluntary survey questionnaire offered to study participants before and after contact with the CASPer test. To evaluate the CASPer test as a predictor of success, we compared CASPer test assessments of personal characteristics versus traditional faculty assessment of personal characteristics with applicant rank list position. All applicants (n = 77) attending an in-person interview for general surgery residency, and all faculty interviewers (n = 34) who reviewed these applications were invited to participate. Among applicants, 84.4% of respondents (65 of 77) reported that a requirement to complete the CASPer test would have no bearing or would make them more likely to apply to the program (mean = 3.30, standard deviation = 0.96). Among the faculty, 62.5% respondents (10 of 16) reported that the same condition would have no bearing or would make applicants more likely to apply to the program (mean = 3.19, standard deviation = 1.33). The Spearman's rank-order correlation coefficients for the relationships between traditional faculty assessment of personal characteristics and applicant rank list position, and novel CASPer assessment of personal characteristics and applicant rank list position, were -0.45 (P = 0.033) and -0.41 (P = 0.055), respectively. The CASPer test may be feasibly implemented as component of the resident selection process, with the potential to predict applicant rank list position and improve the general surgery resident selection process.

    The aim of this study was to evaluate a large-core manual biopsy device (Spirotome(®), Medinvents, 3500 Hasselt, Belgium) for liver sampling and histologic diagnosis in green iguanas (Iguana iguana). The study included eight green iguanas, and two ultrasound-guided biopsies were collected for each lizard, for 16 biopsies in total. The procedure was carried out under general anesthesia induced by intravenous injection of propofol (10 mg/kg) maintained with a mixture of 2.0% isoflurane and 0.8-1.2 L/min oxygen after tracheal intubation. Fourteen (87.5%) of the 16 biopsies were considered diagnostic. Liver biopsy quality was assessed according to sample size and tissue preservation. In particular, mean length (16.2 ± 4.5 mm), width (2.2 ± 0.5 mm), area (34.8 ± 6.9 mm(2)), and number of portal areas (9.4 ± 3.9) of each biopsy were recorded for all green iguanas. The total available surface of the sections obtained from the biopsies and their grade of preservation enabled a satisfactory evaluation of the parenchymal architecture. One of the green iguanas in the study died the day after the procedure due to severe hemocoeloma. Risk assessment evaluation suggested that small green iguanas may not be suitable for this biopsy procedure.

    The present work defines a modified critical size rabbit ulna defect model for bone regeneration in which a non-resorbable barrier membrane was used to separate the radius from the ulna to create a valid model for evaluation of tissue-engineered periosteal substitutes. Eight rabbits divided into two groups were used. Critical defects (15 mm) were made in the ulna completely eliminating periosteum. For group I, defects were filled with a nanohydroxyapatite poly(ester urethane) scaffold soaked in PBS and left as such (group Ia) or wrapped with a tissue-engineered periosteal substitute (group Ib). For group II, an expanded-polytetrafluoroethylene (e-PTFE) (GORE-TEX{sup ®}) membrane was inserted around the radius then the defects received either scaffold alone (group IIa) or scaffold wrapped with periosteal substitute (group IIb). Animals were euthanized after 12–16 weeks, and bone regeneration was evaluated by radiography, computed microtomography (μCT), and histology. In the first group, we observed formation of radio-ulnar synostosis irrespective of the treatment. This was completely eliminated upon placement of the e-PTFE (GORE-TEX{sup ®}) membrane in the second group of animals. In conclusion, modification of the model using a non-resorbable e-PTFE membrane to isolate the ulna from the radius was a valuable addition allowing for objective evaluation of the tissue-engineered periosteal substitute.

    Full Text Available Abstract Background Decision-making in child and youth mental health (CYMH care requires recommendations that are developed through an efficient and effective method and are based on credible knowledge. Credible knowledge is informed by two sources: scientific evidence, and practice-based evidence, that reflects the "real world" experience of service providers. Current approaches to developing these recommendations in relation to CYMH will typically include evidence from one source or the other but do not have an objective method to combine the two. To this end, a modified version of the Grading Recommendations Assessment, Development and Evaluation (GRADE approach was pilot-tested, a novel method for the CYMH field. Methods GRADE has an explicit methodology that relies on input from scientific evidence as well as a panel of experts. The panel established the quality of evidence and derived detailed recommendations regarding the organization and delivery of mental health care for children and youth or their caregivers. In this study a modified GRADE method was used to provide precise recommendations based on a specific CYMH question (i.e. What is the current credible knowledge concerning the effects of parent-implemented, early intervention with their autistic children?. Results Overall, it appeared that early, parent-implemented interventions for autism result in positive effects that outweigh any undesirable effects. However, as opposed to overall recommendations, the heterogeneity of the evidence required that recommendations be specific to particular interventions, based on the questions of whether the benefits of a particular intervention outweighs its harms. Conclusions This pilot project provided evidence that a modified GRADE method may be an effective and practical approach to making recommendations in CYMH, based on credible knowledge. Key strengths of the process included separating the assessments of the quality of the evidence and

    Full Text Available Policymaking in many instances does not follow proper diagnosis of a problem using evidence to justify why particular decisions have been taken. This article describes findings of a diagnostic review of existing challenges facing early childhood development (ECD in South Africa. The review is part of the government’s attempt to use information to drive policy in strategic areas. It is part of the role that the Presidency is seeking to play in ensuring government programmes are evaluated to ensure that money that is spent is spent on programmes that have an impact and that there is value for money. This article summarises the key findings of the diagnostic review that was conducted of policy, services and coordination.The results reveal that a broader definition of ECD programmes is needed to cover all aspects of children’s development, growth and health, from conception to the foundation phase of schooling. Many elements of comprehensive ECD support and services are already in place and some are performing well. However, there are important gaps. Key ECD strategies for the future are identified. The diagnostic evaluation used a variety of methods, including desktop analysis, interviews and data analysis. Issues emerged around how to link the evaluation with other processes in the involved departments. A particular challenge was how to handle the transition to implementation of the findings, as responsibility shifted from the steering committee to the departments. The process worked well despite past challenges with coordination across government.

    This report contains the evaluation and recommendations of a Groundwater Corrective Actions Review Team. The primary goal is to evaluate the technical merit of and the need to implement a proposed groundwater pump-and-treat demonstration project for the Northwest contaminant plume at Paducah, Kentucky. A key distinction recognized by the review team is that the proposed project is intended to be a full-scale hydraulic containment of contaminants migrating from the sources of the plume, not plume remediation. The key questions incorporated into this plan are whether (1) dense, nonaqueous-phase liquids (DNAPLS) are present in the Regional Gravel Aquifer (RGA) at the source of the plume and (2) 99 Tc removal must be included as part of any groundwater treatment process. The first question cannot be answered until the contaminant sources are better defined; the second question requires further risk assessment and/or a policy decision by DOE. Technical evaluation by the review team suggests that the recommended course of action be to modify the proposed work plan to include accurate identification of the sources of contaminants and vertical distribution of contaminants within the Northwest plume before a decision is made on the preferred source-control option. If DNAPLs are not present in the RGA, removal or containment of the sources is recommended. If DNAPLs are present, then hydraulic containment will be required. Finally, the review team recognizes that it is necessary to initiate a more comprehensive analysis of sitewide remediation needs to create links between action taken for the Northwest plume and action taken for other contamination sites at PGPD

    Unstable shoes, which have recently become popular, claim to provide additional physiological and biomechanical advantages to people who wear them. Alterations in postural stability have been shown when using the shoe after training. However, the immediate effect on muscle activity when walking in unstable shoes for the first time has not been investigated. To evaluate muscle activity and temporal parameters of gait when wearing Masai Barefoot Technology shoes(®) for the first time compared to the subject's own regular trainer shoes. A pilot repeated-measures quasi control trial. Electromyographic measurements of lower leg muscles (soleus, medial gastrocnemius, lateral gastrocnemius, tibialis anterior, peroneus longus, rectus femoris, biceps femoris and gluteus medius) were measured in 15 healthy participants using Masai Barefoot Technology shoes and trainer shoes over a 10-m walkway. Muscle activity of the third and sixth steps was used to study the difference in behaviour of the muscles under the two shoe conditions. Temporal parameters were captured with footswitches to highlight heel strike, heel lift and toe off. Paired samples t-test was completed to compare mean muscle activity for Masai Barefoot Technology and trainer shoes. Indicated that the use of Masai Barefoot Technology shoes increased the intensity of the magnitude of muscle activity. While this increase in the activity was not significant across the subjects, there were inter-individual differences in muscle activity. This variance between the participants demonstrates that some subjects do alter muscle behaviour while wearing such shoes. A more rigorous and specific assessment is required when advising patients to purchase the Masai Barefoot Technology shoe. Not all subjects respond positively to using unstable shoes, and the point in time when muscle behaviour can change is variable. Use of Masai Barefoot Technology shoe in patient management should be monitored closely as the individual muscle

    Full Text Available Abstract Background Protein biomarker studies are currently hampered by a lack of measurement standards to demonstrate quality, reliability and comparability across multiple assay platforms. This is especially pertinent for immunoassays where multiple formats for detecting target analytes are commonly used. Findings In this pilot study a generic panel of six non-human protein standards (50 - 10^7 pg/mL of varying abundance was prepared as a quality control (QC material. Simulated "normal" and "diseased" panels of proteins were prepared in pooled human plasma and incorporated into immunoassays using the Meso Scale Discovery® (MSD® platform to illustrate reliable detection of the component proteins. The protein panel was also evaluated as a spike-in material for a model immunoassay involving detection of ovarian cancer biomarkers within individual human plasma samples. Our selected platform could discriminate between two panels of the proteins exhibiting small differences in abundance. Across distinct experiments, all component proteins exhibited reproducible signal outputs in pooled human plasma. When individual donor samples were used, half the proteins produced signals independent of matrix effects. These proteins may serve as a generic indicator of platform reliability. Each of the remaining proteins exhibit differential signals across the distinct samples, indicative of sample matrix effects, with the three proteins following the same trend. This subset of proteins may be useful for characterising the degree of matrix effects associated with the sample which may impact on the reliability of quantifying target diagnostic biomarkers. Conclusions We have demonstrated the potential utility of this panel of standards to act as a generic QC tool for evaluating the reproducibility of the platform for protein biomarker detection independent of serum matrix effects.

    The aim of this pilot study was to evaluate metrologically the effectiveness of a training program on the reduction of stressful trunk postures in geriatric nursing professions. A training program, consisting of instruction on body postures in nursing, practical ergonomic work methods at the bedside or in the bathroom, reorganization of work equipment, and physical exercises, was conducted in 12 wards of 6 nursing homes in Germany. The Computer-Assisted Recording and Long-Term Analysis of Musculoskeletal Loads (CUELA) measurement system was used to evaluate all movements and trunk postures adopted during work before and 6 months after the training program. In total, 23 shifts were measured. All measurements were supported by video recordings. A specific software program (WIDAAN 2.75) was used to synchronize the measurement data and video footage. The median proportion of time spent in sagittal inclinations at an angle of >20° was significantly reduced (by 29%) 6 months after the intervention [from 35.4% interquartile range (27.6-43.1) to 25.3% (20.7-34.1); P 4 s [4.4% (3.0-6.7) to 3.6% (2.5-4.5); P ergonomic measures were implemented properly, either at the bedside or in the bathroom. Stressful trunk postures could be significantly reduced by raising awareness of the physical strains that frequently occur during a shift, by changes in work practices and by redesigning the work environment. Workplace interventions aimed at preventing or reducing low back pain in nursing personnel would probably benefit from sensitizing employees to their postures during work. © The Author 2017.

    2015-01-01

    Full Text Available Introduction: The Nurse-Family Partnership (NFP is a home-visit program for young and first-time, socially and economically disadvantaged mothers. Evidence from three United States randomized controlled trials (RCTs on the effectiveness of this intervention at improving pregnancy outcomes, improving child health and development, and increasing maternal economic self-sufficiency is robust. However, the effectiveness of the NFP in Canada, with its different health and social care context, needs to be determined. The purpose of this article is to describe the complex process for moving the NFP from the research arena to full implementation in Canada. Methods: This process of evaluation in Canada includes (1 adapting the intervention; (2 piloting the intervention in small-scale feasibility and acceptability studies; and (3 conducting an RCT and process evaluation through a study called the British Columbia Healthy Connections Project (BCHCP. This large-scale evaluation also creates an opportunity to expand the NFP evidence base by conducting an additional study to examine potential biological mechanisms linking intervention and behavioural outcomes in children. Results: Adaptation of the NFP home-visit materials is a continuous process. A pilot project determined that it was feasible to enrol eligible women into the NFP. This pilot also determined that, in Canada, it was most appropriate for public health agencies to implement the NFP and for public health nurses to deliver the intervention. Finally, the pilot showed that this intensive home-visit program was acceptable to clients, their family members and health care providers. Through the BCHCP, the next steps—the RCT and process evaluation—are currently underway. The BCHCP will also set the foundation for long-term evaluation of key public health outcomes in a highly vulnerable population of families.

    2013-09-01

    Full Text Available The entire process of olive oil extraction involves the breakage of olive fruits to obtain a paste, the kneading of the paste, a centrifugation, and a further cleaning, performed by a disc stack centrifuge, to separate the residual water. In this research, in order to evaluate the effect of final centrifugal separation on olive oil quality and to both define and design the settings of a innovative separation system, olive oil was separated off from water using an accelerated separation process, tested in comparison with a disc centrifuge. The laboratory plant used for the trials was constituted by a twin cylindrical separator equipped with 4 variable frequency inverters, in order to regulate the fluid flow rates in the plant. Oil samples were collected during the trials to evaluate the influence of the proposed innovative process on oil quality; measuring some parameters as free acidity, peroxides (PV, specific extinction coefficients K232 and K270, chlorophylls , carotenoids, total polyphenols (POL and turbidity. Results showed statistically significant differences (p-values<0.05 in some parameters as POL, PV, and ultraviolet absorption K232 and K270.

    2017-12-01

    Full Text Available The present study explores the value generated by the use of information to rationalize the use of water resources in agriculture. The study introduces the value of information concept in the field of irrigation developing a theoretical assessment framework to evaluate whether the introduction of “Precision Irrigation” (PI practices can improve expectations on income. This is supported by a Stakeholders consultation and by a numerical example, using secondary data and crop growth models. The study reveals that the value generated with the transition to PI varies with pedo-climate, economic, technological and other conditions, and it depends on the initial status of the farmer’s information environment. These factors affect the prerequisite needed to make viable PI. To foster the adoption of PI, stakeholders envisaged the need to set up free meteorological information and advisory service that supports farmers in using PI, as well as other type of instruments. The paper concludes that the profitability of adoption and the relevant impact on the environment cannot be considered as generally given, but must be evaluated case by case justifying (or not the activation of specific agricultural policy measures supporting PI practices to target regions.

    This study aimed to evaluate questionnaire development to measure the knowledge of Complementary-Alternative Medicine (CAM), attitudes towards CAM, CAM experiences, and CAM educational needs of clinical psychologists in Indonesia. A 26-item questionnaire was developed through an extensive literature search. Data was obtained from provisional psychologists from the Master of Professional Clinical Psychology programs at two established public universities in urban areas of Indonesia. To validate the questionnaire, panel reviews by executive members of the Indonesian Clinical Psychology Association (ICPA), experts in health psychology, and experts in public health and CAM provided their professional judgements. The self-reporting questionnaire consisted of four scales including: knowledge of CAM (6 items), attitudes towards CAM (10 items), CAM experiences (4 items), and CAM educational needs (6 items). All scales, except CAM Experiences, were assessed on a 7-point Likert scale. Sixty provisional psychologists were eligible to complete the questionnaire with a response rate of 73% (N=44). The results showed that the CAM questionnaire was reliable (Cronbach's coefficient alpha range=0.62-0.96; item-total correlation range=0.14-0.92) and demonstrated content validity. Following further psychometric evaluation, the CAM questionnaire may provide the evidence-based information to inform the education and practice of Indonesian clinical psychologists.

    Full Text Available Abstract Background Deliberate self harm (DSH is a major public health concern and has increased among young people in Ireland. While DSH is undoubtedly the result of interacting factors, studies have identified an association between DSH and family dysfunction as well as the protective role of positive family relationships. Following a focus group meeting held to identify the needs of parents and carers of young people with DSH, a support programme (SPACE was developed. The aims of the current study are to evaluate the effectiveness of the SPACE programme in decreasing parental psychological distress, reducing parental report of young peoples' difficulties, increasing parental satisfaction and increasing parents' ratings of their own defined challenges and goals. Methods Participants were recruited from a Mental Health Service within a paediatric hospital, Community Child and Adolescent Mental Health Teams and family support services. All services were located within the greater Dublin area in Ireland. Forty-six parents of children who had engaged in or expressed thoughts of self harm attended the programme and participated in the evaluation study. The programme ran once a week over an 8-week period and included topics such as information on self harm in young people, parenting adolescents, communication and parental self-care.

    ABSTRACT: BACKGROUND: Deliberate self harm (DSH) is a major public health concern and has increased among young people in Ireland. While DSH is undoubtedly the result of interacting factors, studies have identified an association between DSH and family dysfunction as well as the protective role of positive family relationships. Following a focus group meeting held to identify the needs of parents and carers of young people with DSH, a support programme (SPACE) was developed. The aims of the current study are to evaluate the effectiveness of the SPACE programme in decreasing parental psychological distress, reducing parental report of young peoples\\' difficulties, increasing parental satisfaction and increasing parents\\' ratings of their own defined challenges and goals. METHODS: Participants were recruited from a Mental Health Service within a paediatric hospital, Community Child and Adolescent Mental Health Teams and family support services. All services were located within the greater Dublin area in Ireland. Forty-six parents of children who had engaged in or expressed thoughts of self harm attended the programme and participated in the evaluation study. The programme ran once a week over an 8-week period and included topics such as information on self harm in young people, parenting adolescents, communication and parental self-care. Seventy percent (N = 32) of the original sample at Time 1 completed measures at Time 2 (directly following the programme) and 37% (N = 17) of the original sample at Time 1 completed them at Time 3 (6 months following the programme).A repeated measures design was used to identify changes in parental wellbeing after attendance at the programme as well as changes in parental reports of their children\\'s difficulties.

    A methodological approach to measuring workload was investigated for evaluation of new concepts in VTOL aircraft displays. Multivariate discriminant functions were formed from conventional flight performance and/or visual response variables to maximize detection of experimental differences. The flight performance variable discriminant showed maximum differentiation between crosswind conditions. The visual response measure discriminant maximized differences between fixed vs. motion base conditions and experimental displays. Physiological variables were used to attempt to predict the discriminant function values for each subject/condition/trial. The weights of the physiological variables in these equations showed agreement with previous studies. High muscle tension, light but irregular breathing patterns, and higher heart rate with low amplitude all produced higher scores on this scale and thus, represented higher workload levels.

    There are very few studies on the need to perform exploratory behaviour of sows around farrowing and during lactation, except for during the nest-building period. Exploratory behaviour in pigs may reflect appetitive foraging motivated by hunger, or appetitive behaviour related to other motivations...... in conventional crates from day 8 before expected farrowing until weaning, on day 28 after farrowing. Motivation to perform exploratory behaviour was evaluated by measuring the use of a manipulable and chewable object (a wooden device, MCO) and responses during a novel object test (NO). In addition, we studied...... if exploratory motivation is related to the energy status of the sow, measured as sow weight change during lactation, piglet weight gain, and leptin level in saliva. The exploratory motivation of sows appeared to change during the period of study. Although all sows used the MCO, the use was very low throughout...

    To evaluate public perceptions towards the causes of depression and schizophrenia and identifications of factors resulting stigma towards mental ill. A cross-sectional study was conducted among the inhabitants of Pulau-Pinang, Malaysia in March, 2009. A 24-item questionnaire was used to obtain respondent views. A non-probability (i.e convenient sampling method) was used to approach the potential respondents. Data analysis was conducted using SPSS version 13 ®, non-parametric statistics (Chi-square) was applied to determine the association. Alpha value less than 0.05 were considered significant. One hundred respondents showed their willingness to participate in the study; overall response of the study was 40.0%. Majority 69% of the respondents were Malays, followed by Chinese and Indians. Public recognition toward depression was higher than schizophrenia. Lack of social support (X(2)= 4.832, P= 0.049), chemical imbalance in Brian (X(2)=6.132, P= 0.013*) and believes in supernatural factors (X(2)= 6.700, P= 0.050) were the commonly shared reasons for the mental disorders. Evaluation in terms of stigma revealed that majority 61 (55.0%). Individuals with mental disorders were not friendly (X(2)= 1.008, P= 0.050). Furthermore, one third of the population believe that they are moody, dangerous and unpredictable, it is better to avoid them. Overall findings revealed that Malaysians believe in supernatural reasons for the prevalence of mental disorders. Similarly the level of stigma towards mentally ill was higher among the respondents.

    Objective : The purpose of this study was to evaluate the perceived effectiveness and learning potential of 3 Web-based educational methods in a postgraduate radiology setting. Methods : Three chiropractic radiology faculty from diverse geographic locations led mini-courses using asynchronous discussion boards, synchronous Web conferencing, and asynchronous voice-over case presentations formatted for Web viewing. At the conclusion of each course, participants filled out a 14-question survey (using a 5-point Likert scale) designed to evaluate the effectiveness of each method in achieving specified course objectives and goals and their satisfaction when considering the learning potential of each method. The mean, standard deviation, and percentage agreements were tabulated. Results : Twenty, 15, and 10 participants completed the discussion board, Web conferencing, and case presentation surveys, respectively. All educational methods demonstrated a high level of agreement regarding the course objective (total mean rating >4.1). The case presentations had the highest overall rating for achieving the course goals; however, all but one method still had total mean ratings >4.0 and overall agreement levels of 70%-100%. The strongest potential for interactive learning was found with Web conferencing and discussion boards, while case presentations rated very low in this regard. Conclusions : The perceived effectiveness in achieving the course objective and goals was high for each method. Residency-based distance education may be a beneficial adjunct to current methods of training, allowing for international collaboration. When considering all aspects tested, there does not appear to be a clear advantage to any one method. Utilizing various methods may be most appropriate.

    Purpose: To develop and evaluate a structured didactic curriculum to complement clinical experiences during radiation oncology clerkships at 2 academic medical centers. Methods and Materials: A structured didactic curriculum was developed to teach fundamentals of radiation oncology and improve confidence in clinical competence. Curriculum lectures included: (1) an overview of radiation oncology (history, types of treatments, and basic clinic flow); (2) fundamentals of radiation biology and physics; and (3) practical aspects of radiation treatment simulation and planning. In addition, a hands-on dosimetry session taught students fundamentals of treatment planning. The curriculum was implemented at 2 academic departments in 2012. Students completed anonymous evaluations using a Likert scale to rate the usefulness of curriculum components (1 = not at all, 5 = extremely). Likert scores are reported as (median [interquartile range]). Results: Eighteen students completed the curriculum during their 4-week rotation (University of Chicago n=13, Harvard Longwood Campus n=5). All curriculum components were rated as extremely useful: introduction to radiation oncology (5 [4-5]); radiation biology and physics (5 [5-5]); practical aspects of radiation oncology (5 [4-5]); and the treatment planning session (5 [5-5]). Students rated the curriculum as “quite useful” to “extremely useful” (1) to help students understand radiation oncology as a specialty; (2) to increase student comfort with their specialty decision; and (3) to help students with their future transition to a radiation oncology residency. Conclusions: A standardized curriculum for medical students completing a 4-week radiation oncology clerkship was successfully implemented at 2 institutions. The curriculum was favorably reviewed. As a result of completing the curriculum, medical students felt more comfortable with their specialty decision and better prepared to begin radiation oncology residency.

    Full Text Available Objectives: The overall aim of this study was to evaluate the perception of and annoyance due to the noise from wind turbines in populated areas of Poland. Material and Methods: The study group comprised 156 subjects. All subjects were asked to fill in a questionnaire developed to enable evaluation of their living conditions, including prevalence of annoyance due to the noise from wind turbines and the self-assessment of physical health and well-being. In addition, current mental health status of the respondents was assessed using Goldberg General Health Questionnaire GHQ-12. For areas where the respondents lived, A-weighted sound pressure levels (SPLs were calculated as the sum of the contributions from the wind power plants in the specific area. Results: It has been shown that the wind turbine noise at the calculated A-weigh­ted SPL of 30-48 dB was noticed outdoors by 60.3% of the respondents. This noise was perceived as annoying outdoors by 33.3% of the respondents, while indoors by 20.5% of them. The odds ratio of being annoyed outdoors by the wind turbine noise increased along with increasing SPLs (OR = 2.1; 95% CI: 1.22-3.62. The subjects' attitude to wind turbines in general and sensitivity to landscape littering was found to have significant impact on the perceived annoyance. About 63% of variance in outdoors annoyance assessment might be explained by the noise level, general attitude to wind turbines and sensitivity to landscape littering. Conclusions: Before firm conclusions can be drawn further studies are needed, including a larger number of respondents with different living environments (i.e., dissimilar terrain, different urbanization and road traffic intensity.

    The Web-based Simulation of Patients (Web-SP) project was initiated in order to facilitate the use of realistic and interactive virtual patients (VP) in medicine and healthcare education. Web-SP focuses on moving beyond the technology savvy teachers, when integrating simulation-based education into health sciences curricula, by making the creation and use of virtual patients easier. The project strives to provide a common generic platform for design/creation, management, evaluation and sharing of web-based virtual patients. The aim of this study was to evaluate if it was possible to develop a web-based virtual patient case simulation environment where the entire case authoring process might be handled by teachers and which would be flexible enough to be used in different healthcare disciplines. The Web-SP system was constructed to support easy authoring, management and presentation of virtual patient cases. The case authoring environment was found to facilitate for teachers to create full-fledged patient cases without the assistance of computer specialists. Web-SP was successfully implemented at several universities by taking into account key factors such as cost, access, security, scalability and flexibility. Pilot evaluations in medical, dentistry and pharmacy courses shows that students regarded Web-SP as easy to use, engaging and to be of educational value. Cases adapted for all three disciplines were judged to be of significant educational value by the course leaders. The Web-SP system seems to fulfil the aim of providing a common generic platform for creation, management and evaluation of web-based virtual patient cases. The responses regarding the authoring environment indicated that the system might be user-friendly enough to appeal to a majority of the academic staff. In terms of implementation strengths, Web-SP seems to fulfil most needs from course directors and teachers from various educational institutions and disciplines. The system is currently in

    Digital storytelling ('digistories') offers a way of sharing the personal impact of a condition, if students have limited direct contact. Autistic spectrum disorder (ASD) exemplifies a common condition, where there is need to improve practise in primary care. Hence, we chose this condition to develop and evaluate a digistory. We considered stigmatising attitudes to ASD and wider educational effects. In the digistory, a mother of a boy with severe ASD describes her autobiographical experiences, illustrated by customised cartoons. Participants completed, pre-post, a validated attitude questionnaire and word association exercise. Views on educational value were gathered through free text and focus group. Questionnaire scores indicated positive attitudes, with no significant change. In contrast, content analysis of word association responses showed prevalent negative associations. Thematic analysis identified increased empathy of students with the family, enabled by the resource design. The digistory helped students challenge stereotypes associated with the condition and encouraged greater confidence to engage in future clinical encounters. The digistory is an accessible and authentic patient analogue that gives additional insight into living with autistic spectrum disorder, with potential benefits for patient-centred learning.

    Optical coherence tomography (OCT) has been investigated as a novel diagnostic imaging tool. The utilisation of this equipment has been evaluated through several studies in the field of dentistry. The aim of this preliminary study was to determine through basic experiments the effectiveness of OCT in implant dentistry. To assess detection ability, we captured OCT images of implants in each of the following situations: (1) implants covered with mucosae of various thicknesses that were harvested from the mandibles of pigs; (2) implants installed in the mandibles of pigs; and (3) implants with abutments and crowns fixed with temporary cement. The OCT images were captured before cementation, after cementation, and after removing the excess submucosal cement. If the thickness of the mucosa covering the implant body was less than 1 mm, the images of the implants were clearly detected by OCT. In the implants were installed in pigs' mandibles, it was difficult to capture clear images of the implant and alveolar bone in most of the samples. Remnants of excess cement around the implants were visible in most samples that had a mucosa thickness of less than 3 mm. Currently, OCT imaging of implants is limited. Cement remnants at the submucosal area can be detected in some cases, which can be helpful in preventing peri-implant diseases. Still, though there are some restrictions to its application, OCT could have potential as an effective diagnostic instrument in the field of implant dentistry as well

    The Washington State Department of Ecology (Ecology) is developing guidelines to assess soil toxicity at hazardous waste sites being investigated under the Washington Model Toxics Control Act Cleanup Regulation. To evaluate soil toxicity, Ecology selected five bioassay protocols -- Daphnia, Earthworm, Seedling, Fathead Minnow, and Frog Embryo Teratogenesis Assay Xenopus (FETAX) -- for use as screening level assessment tools at six State hazardous waste sites. Sites contained a variety of contaminants including metals, creosote, pesticides, and petroleum products (leaking underground storage tanks). Three locations, representing high, medium, and low levels of contamination, were samples at each site. In general, the high contaminant samples resulted in the highest toxic response in all bioassays. The order of site toxicity, as assessed by overall toxic response, is creosote, petroleum products, metals, and pesticides. Results indicate that human health standards, especially for metals, may not adequately protect some of the species tested. The FETAX bioassay had the greatest overall number of toxic responses and lowest variance. The seedling and Daphnia bioassays had lower and similar overall toxic response results, followed by the earthworm and fathead minnow. Variability was markedly highest for the seedling. The Daphnia and fathead minnow variability were similar to the FETAX level, while the earthworm variability was slightly higher

    Thousands of children are bereaved each year by suicide, yet there exists very little literature specifically on the psychological care, programs, and interventions available to help them. (1) To build and validate theoretical models for the Group Therapy Program for Children Bereaved by Suicide (PCBS); (2) to test these models in a preliminary evaluation. In the first part, we built theoretical models, which were then validated by scientists and clinicians. In the second part, the sessions of the PCBS were observed and rated. The participating children were tested pre- and postprogram. Positive changes were observed in the participating children in terms of basic safety, realistic understanding and useful knowledge, inappropriate behaviors, physical and psychological symptoms, child-parent and child-child communication, capacity for social and affective reinvestment, actualization of new models of self and the world, self-esteem, awareness and use of tools, cognitive, verbal, written and drawing abilities, cognitive dissonance, ambivalence, antagonism, and isolation. The changes reported in the bereaved children show that the PCBS has some efficacy.

    The literature on occupational safety and health (OSH) interventions contains many debates on how interventions should work, but far less attention has been paid to how they actually do work, and to the contextual factors that influence their implementation, development and effect. The need of improving the understanding of the OSH interventions issue is particularly relevant for small and medium-sized enterprises (SMEs), since they experience worse OSH conditions, and have fewer physical, economic and organizational resources if compared to larger enterprises; thus, SMEs strongly need to focus their few resources in the decision-making process so as to select and put in place only the most proper interventions. This exploratory study is based on interviews with safety officers of 5 SMEs, and it gives an overview of the key features of the actual intervention process in SMEs and of the contextual factors making this actual intervention process similar or dissimilar to the ideal case. The results show how much qualitative and experience driven the actual intervention process is; they should be used to direct the future research towards an increasingly applicable one, to enable practitioners from SMEs to develop, implement and evaluate their OSH interventions in an "ideal" way.

    Full Text Available Objectives. The main objective was to determine how the depth of probe placement affects functional and resting bioelectrical activity of the PFM and whether the recorded signal might be dependent on the direction in which the probe is rotated. Participants. The study comprised of healthy, nulliparous women between the ages of 21 and 25. Outcome Measures. Bioelectric activity of the PFM was recorded from four locations of the vagina by surface EMG and vaginal probe. Results. There were no statistically significant differences between the results during functional sEMG activity. During resting sEMG activity, the highest bioelectrical activity of the PFM was observed in the L1 and the lowest in the L4 and a statistically significant difference between the highest and the lowest results of resting sEMG activity was observed (P=0.0043. Conclusion. Different electrodes placement during functional contraction of PFM does not affect the obtained results in sEMG evaluation. In order to diagnose the highest resting activity of PFM the recording plates should be placed toward the anterior vaginal wall and distally from the introitus. However, all of the PFM have similar bioelectrical activity and it seems that these muscles could be treated as a single muscle.

    To evaluate the efficacy and applicability of a HACCP-based program for use in restaurants. A randomly selected sample of 16 intervention and 42 control full service, "stand-alone" restaurants with a minimum of 3 full-time food handling staff on duty per shift. Six communities in Central West Ontario. The Critical Approach, a HACCP-based program for use in restaurants, was designed in consultation with health inspectors and restaurant operators. It focusses on generic risk factors (Critical Control Points, CCPs) for food handlers rather than assessing specific menu items or foods; offers appropriate training of both management and staff; and encourages self-monitoring of CCPs by operators without extensive record keeping or retention. Outcome indicators measured changes in three areas: the environment, knowledge, and behaviour. Results suggest that among a subpopulation of restaurants, the program is acceptable to operators and capable of producing tangible results. Principles and methods of the program (i.e., an initial assessment of the site, working with the operator to identify and suggest improvements, and return visits to monitor compliance) may be transferable to other types of food service operations.

    This paper presents a comparison of combustion of coal alone with that of a mixture of coal with sewage sludge with respect to flue gas emissions, the behaviour of heavy metals and potential environmental consequences of disposal of ashes produced. Co-combustion with sludge did not result in greater NOx, SO{sub 2}, HCl and CO emissions and the use of air staging and the addition of limestone proved to be effective to reduce NOx and SO{sub 2}. The mixing of sludge gave rise to an increase in amounts of heavy metals released, especially for Cd, Pb and Hg. However, as they were associated with particles greater than 1 {micro}m, the application of efficient flue gas treatment devices could decrease their emissions to the atmosphere. Metals were essentially retained in ashes captured in the bed and in the cyclones and most of the Hg was adsorbed in fly ashes that contained unburned carbon. The leachability of metals and organic matter present in the sludge decreased with combustion. The evaluation of the acid neutralization capacity (ANC) showed that ashes became more resistant to acidification than the parent sludge. Globally, this study concludes that the implication of the combustion of sludge is that it can reduce the negative impact on the environment compared with the traditional direct use of sludge in soils. 22 refs., 4 figs., 5 tabs.

    How did the work of four school coaches in five Saxonian schools influence children's and adolescents' psychosocial development? At three points in time, students at intervention (N = 292) and control schools (N = 300) were evaluated concerning their social distance towards mentally ill people and their help-seeking behavior in case of crisis. The survey also included teachers (N = 323) and parents (N = 370). Data analysis was done descriptively and with random effects models. The social distance of the intervention schools declined significantly compared to the control schools. Having heard or read about mental illnesses, or personally knowing somebody affected by mental illness, led to less social distance and more empathy. Information increased the confidence to receive help from a professional consultant. Friends and family were the main reference groups. The school coaches were accepted as confidential persons and helped with school and private issues. The school coaches' work showed positive influence on all members of the school system. © Georg Thieme Verlag KG Stuttgart · New York.

    Full Text Available Purpose: The purpose of this study was evaluation of the current status of medical students' documentation of patient medical records. Methods: We checked the completeness, appropriateness, and accuracy of 95 Subjective-Objective-Assessment-Plan (SOAP notes documented by third-year medical students who participated in clinical skill tests on December 1, 2014. Students were required to complete the SOAP note within 15 minutes of an standard patient (SP-encounter with a SP complaining rhinorrhea and warring about meningitis. Results: Of the 95 SOAP notes reviewed, 36.8% were not signed. Only 27.4% documented the patient’s symptoms under the Objective component, although all students completed the Subjective notes appropriately. A possible diagnosis was assessed by 94.7% students. Plans were described in 94.7% of the SOAP notes. Over half the students planned workups (56.7% for diagnosis and treatment (52.6%. Accurate documentation of the symptoms, physical findings, diagnoses, and plans were provided in 78.9%, 9.5%, 62.1%, and 38.0% notes, respectively. Conclusion: Our results showed that third-year medical students’ SOAP notes were not complete, appropriate, or accurate. The most significant problems with completeness were the omission of students’ signatures, and inappropriate documentation of the physical examinations conducted. An education and assessment program for complete and accurate medical recording has to be developed.

    An acceptable area for collecting DNA reference sample is a part of the forensic DNA analysis development. The aim of this study was to evaluate skin surface cells (SSC) as an alternate source of reference DNA sample. From each volunteer (n = 10), six samples from skin surface areas (forearm and fingertips) and two traditional samples (blood and buccal cells) were collected. Genomic DNA was extracted and quantified then genotyped using standard techniques. The highest DNA concentration of SSC samples was collected using the tape/forearm method of collection (2.1 ng/μL). Cotton swabs moistened with ethanol yielded higher quantities of DNA than swabs moistened with salicylic acid, and it gave the highest percentage of full STR profiles (97%). This study supports the use of SSC as a noninvasive sampling technique and as a extremely useful source of DNA reference samples among certain cultures where the use of buccal swabs can be considered socially unacceptable. © 2017 American Academy of Forensic Sciences.

    Full Text Available Research on the dental restorative materials employed in remedying dental cavities has been conducted on many levels and areas, both with application of clinical and laboratory methods. One of the elements that determines whether the restoration may be degraded is the condition of its surface. The aim of the study was to assess the texture surface of composite restorations using a non-contact method of teeth models scanning. In this work, ten medium size cavities on the occlusal surfaces of molars in adult patients were prepared and restored with resin composite. Before undertaking the procedure and after the finishing and polishing of the restorations, impressions were taken and sent into the laboratory so as to prepare plaster casts. Every cast was then scanned utilizing the non-contact 3D surface measurement instrument so as to assess the texture surface of the restoration. The resulting three dimensional analyses of post-restoration models showed the correct marginal adaptation of resin composite dental material to the hard tooth structures and its smooth filling occlusal surface. Additional comparison of scans done before and after restoring the cavities allowed the calculating of differences in volume, mean and maximum heights. The applied method of analysis is thought to be helpful in the detailed evaluation of restoration dental material texture. Moreover, the enabled possibility of continuous observation is expedient for assessing the usefulness of the method in standard dental practice.

    Optical coherence tomography (OCT) has been investigated as a novel diagnostic imaging tool. The utilisation of this equipment has been evaluated through several studies in the field of dentistry. The aim of this preliminary study was to determine through basic experiments the effectiveness of OCT in implant dentistry. To assess detection ability, we captured OCT images of implants in each of the following situations: (1) implants covered with mucosae of various thicknesses that were harvested from the mandibles of pigs; (2) implants installed in the mandibles of pigs; and (3) implants with abutments and crowns fixed with temporary cement. The OCT images were captured before cementation, after cementation, and after removing the excess submucosal cement. If the thickness of the mucosa covering the implant body was less than 1 mm, the images of the implants were clearly detected by OCT. In the implants were installed in pigs' mandibles, it was difficult to capture clear images of the implant and alveolar bone in most of the samples. Remnants of excess cement around the implants were visible in most samples that had a mucosa thickness of less than 3 mm. Currently, OCT imaging of implants is limited. Cement remnants at the submucosal area can be detected in some cases, which can be helpful in preventing peri-implant diseases. Still, though there are some restrictions to its application, OCT could have potential as an effective diagnostic instrument in the field of implant dentistry as well.

    Full Text Available Aim: To investigate the effect of Emdogain gel (EMD in pulpotomized primary molars and its clinical and radiographic outcomes. Methods and Materials: In this   study, 18 lower second primary molars of nine children were treated by   pulpotomy. The teeth were randomly assigned to the EMD (experimental and Formocresol (control groups in each patient (split mouth. Following removal of the coronal pulp and haemostasis, the pulp stumps were covered with Emdogain gel in the experimental group followed by application of resin-modified glass ionomer cement over the gel. In the control group, Formocresol (FC was placed with a cotton pellet over the pulp stumps. Lastly, the teeth in both groups were restored with stainless steel crowns. Results: Nine children referred with clinical failure before/at two months follow up. The radiographic evaluation revealed furcation involvement and extensive radicular radiolucency in molars treated with Emdogain gel. Conclusion: The present study showed the failure of enamel matrix derivative in pulpotomy of primary molars; therefore, we do not recommend using Emdogain as a pulpotomy agent for treatment of cariously exposed primary teeth

    Youth in the child welfare system (CWS) have substantially higher rates of mental health needs compared to the general population, yet they rarely receive targeted, evidence-based practices (EBPs). Caseworkers play the critically important role of "service broker" for CWS youth and families. This study examines preliminary caseworker-level outcomes of Project Focus Colorado (PF-C), a training and consultation program designed to improve access to EBPs for CWS youth. PF-C evaluation occurred in four child welfare offices (two intervention [n = 16 caseworkers] vs. two practice-as-usual, wait-list control [WLC; n = 12 caseworkers]). Receipt of PF-C was associated with significantly increased caseworker knowledge of (a) EBPs, (b) child mental health problems, (c) evidence-based treatment components targeting mental health problem areas, and (d) mental health screening instruments, compared to WLC. Dose of training and consultation was associated with greater ability to correctly classify mental health problems and match them to EBPs. These preliminary results suggest that targeted training and consultation help to improve caseworker knowledge of children's mental health needs, EBPs for mental health, and mental health screening instruments. © The Author(s) 2014.

    The health of an airline pilot is imperative to the safe travels of millions of people worldwide. Medical providers evaluate the cardiovascular risks for airline pilots and the medical requirements to obtain and maintain licensure as an airline pilot. It is the role of the occupational health nurse practitioner to evaluate and reduce the risk of cardiovascular disease in this population.

    Eating disorders cause significant burden that may be reduced by early and appropriate help-seeking. However, despite the availability of effective treatments, very few individuals with eating disorders seek treatment. Training in mental health first aid is known to be effective in increasing mental health literacy and supportive behaviours, in the social networks of individuals with mental health problems. Increases in these domains are thought to improve the likelihood that effective help is sought. However, the efficacy of mental health first aid for eating disorders has not been evaluated. The aim of this research was to examine whether specific training in mental health first aid for eating disorders was effective in changing knowledge, attitudes and behaviours towards people with eating disorders. A repeated measures, uncontrolled trial was conducted to establish proof of concept and provide guidance on the future design of a randomised controlled trial. Self-report questionnaires, administered at baseline, post-training and 6-month follow-up, assessed the effectiveness of the 4-hour, single session, mental health first aid training. 73 participants completed the training and all questionnaires. The training intervention was associated with statistically significant increases in problem recognition and knowledge of appropriate mental health first aid strategies, which were maintained at 6-month follow-up. Sustained significant changes in attitudes and behaviours were less clear. 20 participants reported providing assistance to someone with a suspected eating disorder, seven of whom sought professional help as a result of the first aid interaction. Results provided no evidence of a negative impact on participants or the individuals they provided assistance to. This research provides preliminary evidence for the use of training in mental health first aid as a suitable intervention for increasing community knowledge of and support for people with eating

    Objective To evaluate the effectiveness and cost of the pan-London pharmacy initiative, a programme that allows administration of seasonal influenza vaccination to eligible patients at pharmacies. Design We analysed 2013–2015 data on vaccination uptake in pharmacies via the Sonar reporting system, and the total vaccination uptake via 2011–2015 ImmForm general practitioner (GP) reporting system data. We conducted an online survey of London pharmacists who participate in the programme to assess time use data, vaccine choice, investment costs and opinions about the programme. We conducted an online survey of London GPs to assess vaccine choice of vaccine and opinions about the pharmacy vaccine delivery programme. Setting All London boroughs. Participants London-based GPs, and pharmacies that currently offer seasonal flu vaccination. Interventions Not applicable. Main outcome measures Comparison of annual vaccine uptake in London across risk groups from years before pharmacy vaccination introduction to after pharmacy vaccination introduction. Completeness of vaccine uptake reporting data. Cost to the National Health Service (NHS) of flu vaccine delivery at pharmacies with that at GPs. Cost to pharmacists of flu delivery. Opinions of pharmacists and GPs regarding the flu vaccine pharmacy initiative. Results No significant change in the uptake of seasonal vaccination in any of the risk groups as a result of the pharmacy initiative. While on average a pharmacy-administered flu vaccine dose costs the NHS up to £2.35 less than a dose administered at a GP, a comparison of the 2 recording systems suggests there is substantial loss of data. Conclusions Flu vaccine delivery through pharmacies shows potential for improving convenience for vaccine recipients. However, there is no evidence that vaccination uptake increases and the use of 2 separate recording systems leads to time-consuming data entry and missing vaccine record data. PMID:26883237

    Improvements of soft tissue to the abutment surface results in more stable peri-implant conditions, however, few human histological studies have compared soft tissue responses around different abutment materials. To describe the peri-implant tissue around 3 abutment materials; titanium, zirconia, and gold alloy, over an 8-week healing period. Fifteen edentulous sites were treated with implants. Eight weeks later, peri-implant tissue was harvested and processed using a nonseparation resin embedded technique. The tissue attachment characteristics were assessed at clinical stages using the gingival index (GI) score, surgical stage (surgical score), and histological stage (histological attachment percentage). Additionally, the inflammatory responses were evaluated using inflammatory extent and inflammatory cellularity grades. Nonparametrical statistics were used to describe the GI and surgical scores, and analytical statistics were used to analyze the histological attachment percentages as well as the inflammatory extent and cellularity grades amongst the 3 groups. There were no statistically significant differences among the groups for GI score (P = .071) and surgical score (P = .262). Titanium and zirconia exhibited nearly similar mean histological attachment percentages while gold alloy had a significantly lower percentage (P = .004). For the inflammatory extent and cellularity grades, the odds of being one grade higher for gold alloy abutment was 5.18 and 17.8 times that of titanium abutment, respectively. However, for the zirconia abutment, the odds were 0.87 and 7.5 times higher than the titanium group. The tissue around the gold alloy abutments resulted in worse attachment conditions compared with the titanium and zirconia abutments. Inflammation tended to be higher in the tissue around the gold alloy abutments than the titanium and zirconia abutments. © 2017 Wiley Periodicals, Inc.

    Mental health clinicians can experience difficulties communicating diagnostic information to patients and their families/carers, especially about distressing psychiatric disorders such as schizophrenia. There is evidence for the effectiveness of communication skills training (CST) for improving diagnostic discussions, particularly in specialties such as oncology, but only limited evidence exists about CST for psychiatry. This study evaluated a CST program specifically developed for psychiatry residents called ComPsych that focuses on conveying diagnostic and prognostic information about schizophrenia. The ComPsych program consists of an introductory lecture, module booklets for trainees, and exemplary skills videos, followed by small group role-plays with simulated patients (SPs) led by a trained facilitator. A standardized patient assessment (SPA) was digitally recorded pre- and post-training with a SP using a standardized scenario in a time-limited (15 min) period. Recorded SPAs were independently rated using a validated coding system (ComSkil) to identify frequency of skills used in five skills categories (agenda setting, checking, questioning, information organization, and empathic communication). Thirty trainees (15 males and 15 females; median age = 32) undertaking their vocational specialty training in psychiatry participated in ComPsych training and pre- and post-ComPsych SPAs. Skills increased post-training for agenda setting (d = -0.82), while questioning skills (d = 0.56) decreased. There were no significant differences in any other skills grouping, although checking, information organization, and empathic communication skills tended to increase post-training. A dose effect was observed for agenda setting, with trainees who attended more CST sessions outperforming those attending fewer. Findings support the generalization and translation of ComPsych CST to psychiatry.

    Interprofessional teams provide the promise of effective, comprehensive and reliable care. Interprofessional education (IPE) promotes students' knowledge and attitudes to support interprofessional teamwork, and problem-based learning formats enable students to gain valuable teamwork experience. To design, implement, and evaluate an interprofessional problem-based learning module in a large Canadian university focusing on the effects of this format on students' knowledge, attitudes, and perceptions. A pre-post mixed-methods research design was used, with a convenience sample of 24 students from medicine, pharmacy, nursing, physical therapy, and occupational therapy. Participants in the module were divided into 5 teams composed of one member from each discipline. Pre-tests were delivered just prior to module participation and post-tests directly followed. Students also participated in focus groups to provide feedback about module content, process, outcomes, and practical considerations. Students' attitudes toward interprofessional teamwork improved from baseline to post-intervention. Mean differences were significant using paired t-tests on confidence in professional role (p <0.001), communication (p = 0.02), understanding roles of others (p = 0.002), identification with the team (p = 0.002), comfort with members (p = 0.047), cooperation with team members (p = 0.004), team perceptions (p = 0.04), decision-making (p <0.001), team efficiency (p <0.001), minimal conflict (p = 0.04), and group contributions (p = 0.03). Focus group themes indicated students were satisfied with the module, perceived increased knowledge about roles and perspectives, greater confidence to collaborate, and increased motivation to engage in intra-curricular IPE. The timing of their exposure within their respective educational programs was identified as important.

    Full Text Available Abstract Background Independent of efficacy, information on safety of surgical procedures is essential for informed choices. We seek to develop standardized methodology for describing the safety of spinal operations and apply these methods to study lumbar surgery. We present a conceptual model for evaluating the safety of spine surgery and describe development of tools to measure principal components of this model: (1 specifying outcome by explicit criteria for adverse event definition, mode of ascertainment, cause, severity, or preventability, and (2 quantitatively measuring predictors such as patient factors, comorbidity, severity of degenerative spine disease, and invasiveness of spine surgery. Methods We created operational definitions for 176 adverse occurrences and established multiple mechanisms for reporting them. We developed new methods to quantify the severity of adverse occurrences, degeneration of lumbar spine, and invasiveness of spinal procedures. Using kappa statistics and intra-class correlation coefficients, we assessed agreement for the following: four reviewers independently coding etiology, preventability, and severity for 141 adverse occurrences, two observers coding lumbar spine degenerative changes in 10 selected cases, and two researchers coding invasiveness of surgery for 50 initial cases. Results During the first six months of prospective surveillance, rigorous daily medical record reviews identified 92.6% of the adverse occurrences we recorded, and voluntary reports by providers identified 38.5% (surgeons reported 18.3%, inpatient rounding team reported 23.1%, and conferences discussed 6.1%. Trained observers had fair agreement in classifying etiology of 141 adverse occurrences into 18 categories (kappa = 0.35, but agreement was substantial (kappa ≥ 0.61 for 4 specific categories: technical error, failure in communication, systems failure, and no error. Preventability assessment had moderate agreement (mean weighted

    Atmospheric CO2 concentration is influenced by human activities and by natural exchanges. Studies of CO2 fluxes using atmospheric CO2 measurements typically focus on natural exchanges and assume that CO2 emissions by fossil fuel combustion and cement production are well-known from inventory estimates. However, atmospheric observation-based or "top-down" studies could potentially provide independent methods for evaluating fossil fuel CO2 emissions, in support of policies to reduce greenhouse gas emissions and mitigate climate change. Observation-based estimates of fossil fuel-derived CO2 may also improve estimates of biospheric CO2 exchange, which could help to characterize carbon storage and climate change mitigation by terrestrial ecosystems. We have been developing a top-down framework for estimating fossil fuel CO2 emissions in California that uses atmospheric observations and modeling. California is implementing the "Global Warming Solutions Act of 2006" to reduce total greenhouse gas emissions to 1990 levels by 2020, and it has a diverse array of ecosystems that may serve as CO2 sources or sinks. We performed three month-long field campaigns in different seasons in 2014-15 to collect flask samples from a state-wide network of 10 towers. Using measurements of radiocarbon in CO2, we estimate the fossil fuel-derived CO2 present in the flask samples, relative to marine background air observed at coastal sites. Radiocarbon (14C) is not present in fossil fuel-derived CO2 because of radioactive decay over millions of years, so fossil fuel emissions cause a measurable decrease in the 14C/C ratio in atmospheric CO2. We compare the observations of fossil fuel-derived CO2 to simulations based on atmospheric modeling and published fossil fuel flux estimates, and adjust the fossil fuel flux estimates in a statistical inversion that takes account of several uncertainties. We will present the results of the top-down technique to estimate fossil fuel emissions for our field

    Purpose To identify changes in a broad panel of circulating angiogenesis factors after bland transcatheter arterial embolization (TAE), a purely ischemic treatment for hepatocellular carcinoma (HCC). Materials and Methods This prospective HIPAA-compliant study was approved by the institutional review board. Informed written consent was obtained from all participants prior to entry into the study. Twenty-five patients (21 men; mean age, 61 years; range, 30-81 years) with Liver Imaging Reporting and Data System category 5 or biopsy-proven HCC and who were undergoing TAE were enrolled from October 15, 2014, through December 2, 2015. Nineteen plasma angiogenesis factors (angiopoietin 2; hepatocyte growth factor; platelet-derived growth factor AA and BB; placental growth factor; vascular endothelial growth factor A and D; vascular endothelial growth factor receptor 1, 2, and 3; osteopontin; transforming growth factor β1 and β2; thrombospondin 2; intercellular adhesion molecule 1; interleukin 6 [IL-6]; stromal cell-derived factor 1; tissue inhibitor of metalloproteinases 1; and vascular cell adhesion molecule 1 [VCAM-1]) were measured by using enzyme-linked immunosorbent assays at 1 day, 2 weeks, and 5 weeks after TAE and were compared with baseline levels by using paired Wilcoxon tests. Tumor response was assessed according to modified Response Evaluation Criteria in Solid Tumors (mRECIST). Angiogenesis factor levels were compared between responders and nonresponders by mRECIST criteria by using unpaired Wilcoxon tests. Results All procedures were technically successful with no complications. Fourteen angiogenesis factors showed statistically significant changes following TAE, but most changes were transient. IL-6 was upregulated only 1 day after the procedure, but showed the largest increases of any factor. Osteopontin and VCAM-1 demonstrated sustained upregulation at all time points following TAE. At 3-month follow-up imaging, 11 patients had responses to TAE

    Digital techniques are not clinically applied for 1-piece maxillary prostheses containing an obturator and removable partial denture retained by the remaining teeth because of the difficulty in obtaining sufficiently accurate 3-dimensional (3D) images. The purpose of this pilot clinical study was to generate 3D digital casts of maxillary defects, including the defective region and the maxillary dentition, based on multisource data registration and to evaluate their effectiveness. Twelve participants with maxillary defects were selected. The maxillofacial region was scanned with spiral computer tomography (CT), and the maxillary arch and palate were scanned using an intraoral optical scanner. The 3D images from the CT and intraoral scanner were registered and merged to form a 3D digital cast of the maxillary defect containing the anatomic structures needed for the maxillary prosthesis. This included the defect cavity, maxillary dentition, and palate. Traditional silicone impressions were also made, and stone casts were poured. The accuracy of the digital cast in comparison with that of the stone cast was evaluated by measuring the distance between 4 anatomic landmarks. Differences and consistencies were assessed using paired Student t tests and the intraclass correlation coefficient (ICC). In 3 participants, physical resin casts were produced by rapid prototyping from digital casts. Based on the resin casts, maxillary prostheses were fabricated by using conventional methods and then evaluated in the participants to assess the clinical applicability of the digital casts. Digital casts of the maxillary defects were generated and contained all the anatomic details needed for the maxillary prosthesis. Comparing the digital and stone casts, a paired Student t test indicated that differences in the linear distances between landmarks were not statistically significant (P>.05). High ICC values (0.977 to 0.998) for the interlandmark distances further indicated the high

    To design and evaluate a pilot intervention to promote self-management skills and work transition for persons with HIV/AIDS. The seven-week group intervention consisted of 1.5-hour bi-weekly sessions focused on goal setting and developing strategies to manage health, work and daily life routines while participating in a job skills training program in New York City. Six successive groups received the intervention over the course of two years (n = 53). Existing and newly-developed measures were used to examine key outcomes. Differences between pre-intervention and post-intervention scores on outcome measures were examined using paired-tests and effect sizes. Employment outcomes and participant satisfaction were examined post-intervention. The intervention was feasible to implement and sessions were viewed favorably by the majority of participants. Moderate to large effect sizes were found immediately post-intervention in participants' perceived ability to work and balance health, work and daily life. Fifty two percent of the participants were working part or full time and 41% were actively searching for employment at three to five months follow-up. Small effect sizes demonstrating improved outcomes at follow-up were found in symptom severity, self-advocacy and medication adherence self-efficacy. Small effect sizes demonstrating a potential decrement in outcomes at follow-up were found in participants' need satisfaction and perceived symptom impact on work performance. The results are promising, but further research is needed due to design limitations and the preliminary nature of the intervention and measures used. The potential decrement in outcomes might reflect a shift in participants' needs or view of how their health affected work performance and suggests that ongoing supports were needed post-intervention.

The quality of life was also assessed using polycystic ovary syndrome questionnaire (PCOSQ. Materials and Methods: A single-blind, randomised, placebo-controlled pilot study was conducted from February 2014 to May 2015 at two research centres. The cases fulfilling the eligibility criteria were enrolled (n = 60 and randomised to either the homoeopathic intervention (HI (n = 30 or identical placebo (P (n = 30 with uniform lifestyle modification (LSM for 6 months. Results: The menstrual regularity with improvement in other signs/symptoms was observed in 60% of the cases (n = 18 in HI + LSM group and none (n = 0 in control group (P = 0.001. Statistically significant difference (P = 0.016 was observed in reduction of intermenstrual duration (from 76.1 ± 37.7 to 46.6 ± 38.7 days in HI + LSM in comparison to placebo + LSM group (from 93.0 ± 65.2 to 93.9 ± 96.2 days. In PCOSQ, also, significant improvement was observed in HI group in domains of weight, fertility, emotions and menstrual problems (P < 0.05 with no difference in body hair (P = 0.708. No change was observed in respect of improvement in the ultrasound findings. Pulsatilla was the most frequently indicated medicine (n = 12, 40%. Conclusion: HI along with LSM has shown promising outcome; further comparative study with standard conventional treatment on adequate sample size is desirable.

    This multi-center quasi-experimental pilot study aimed to evaluate changes in pain, joint stiffness, physical function, and quality of life over 12 weeks in adults with musculoskeletal conditions attending 'Waves' aquatic exercise classes. A total of 109 adults (mean age, 65.2 years; range, 24-93 years) with musculoskeletal conditions were recruited across 18 Australian community aquatic centers. The intervention is a peer-led, 45 min, weekly aquatic exercise class including aerobic, strength, flexibility, and balance exercises (n = 67). The study also included a control group of people not participating in Waves or other formal exercise (n = 42). Outcomes were measured using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and EuroQoL five dimensions survey (EQ-5D) at baseline and 12 weeks. Satisfaction with Waves classes was also measured at 12 weeks. Eighty two participants (43 Waves and 39 control) completed the study protocol and were included in the analysis. High levels of satisfaction with classes were reported by Waves participants. Over 90 % of participants reported Waves classes were enjoyable and would recommend classes to others. Waves participants demonstrated improvements in WOMAC and EQ-5D scores however between-group differences did not reach statistical significance. Peer-led aquatic exercise classes appear to improve pain, joint stiffness, physical function and quality of life for people with musculoskeletal conditions. The diverse study sample is likely to have limited the power to detect significant changes in outcomes. Larger studies with an adequate follow-up period are needed to confirm effects.

    To clarify the duration required for dyspnea to return to baseline severity after fan therapy, to evaluate whether fan-to-legs therapy or no fan therapy would be a suitable control therapy, and to investigate changes in patients' face surface temperature after fan therapy. In this pilot study, all participants received 3 interventions in the following order: no fan, fan to legs, and fan to face. Participants used a fan for 5 minutes, and they scored their dyspnea at 10-minute intervals for 60 minutes or until the score had returned to its baseline value, whichever occurred first. Nine patients with advanced cancer admitted to a palliative care unit were included; they had dyspnea at rest and rated its severity as at least 3 points on a 0- to 10-point numerical rating scale. Descriptive statistics and the Wilcoxon signed rank test were used to analyze the data. All patients completed the study. Of the 9 participants, 6 experienced a clinical benefit from using a fan to their faces. Of these patients, only 2 participants' (2 of 6) dyspnea scores returned to baseline by the end of the 60-minute assessment period after exposure to fan-to-face therapy. In fan-to-legs and no fan settings, there was no change in the dyspnea scores. There were significant differences between the baseline face surface temperature and that after fan-to-face and fan-to-legs settings. When using a crossover design to investigate the effect of fan therapy on dyspnea, 1 hour is an insufficient washout period.

    A Revolving Algal Biofilm (RAB) growth system in which algal cells are attached to a flexible material rotating between liquid and gas phases has been developed. In this work, different configurations of RAB systems were developed at pilot-scale by retrofitting the attachment materials to a raceway pond (2000-L with 8.5 m(2) footprint area) and a trough reservoir (150 L with 3.5 m(2) footprint area). The algal growth performance and chemical composition, as well as the water evaporative loss and specific water consumption were evaluated over a period of nine months in a greenhouse environment near Boone, Iowa USA. Additionally a raceway pond was run in parallel, which served as a control. On average the raceway-based RAB and the trough-based RAB outperformed the control pond by 309% and 697%, respectively. A maximum productivity of 46.8 g m(-2) day(-1) was achieved on the trough-based RAB system. The evaporative water loss of the RAB system was modeled based on an energy balance analysis and was experimentally validated. While the RAB system, particularly the trough-based RAB, had higher water evaporative loss, the specific water consumption per unit of biomass produced was only 26% (raceway-based RAB) and 7% (trough-based RAB) of that of the control pond. Collectively, this research shows that the RAB system is an efficient algal culture system and has great potential to commercially produce microalgae with high productivity and efficient water use. © 2015 Wiley Periodicals, Inc.

    Meeting the complex needs of patients with chronic common mental health disorders (CMHDs) may be the greatest challenge facing organized medical practice. On the basis of a well-established and proven theoretical foundation for controlled respiration as a behavioral intervention for CMHDs, as well as preliminary evidence that gamification can improve health outcomes through increasing patient engagement, this randomized controlled pilot study evaluated the feasibility and clinical efficacy of a mobile health game called "Flowy" ( www.flowygame.com ) that digitally delivered breathing retraining exercises for anxiety, panic, and hyperventilation symptom management. We designed an unblinded, Web-based, parallel-group randomized controlled trial focusing on feasibility, clinical efficacy, and design proof of concept. In the intervention condition (n = 31), participants received free access to "Flowy" for 4 weeks. In the control condition (n = 32), participants were placed on a waitlist for 4 weeks before being offered free access to "Flowy." Online measurements using psychological self-report questionnaires were made at 2 and 4 weeks post-baseline. At trial conclusion, participants found "Flowy" acceptable as an anxiety management intervention. "Flowy" engaged participants sufficiently to endorse proactive gameplay. Intent-to-treat analysis revealed a reduction in anxiety, panic, and self-report hyperventilation scores in both trial arms, with the intervention arm experiencing greater quality of life. Participants perceived "Flowy" as a fun and useful intervention, proactively used "Flowy" as part of their care, and would recommend "Flowy" to family and friends. Our results suggest that a digital delivery of breathing retraining exercises through a mobile health game can manage anxiety, panic, and hyperventilation symptoms associated with CMHDs.

    This paper reports on one aspect of the evaluation of the midwifery pilot projects in Quebec: the identification of the professional and organizational factors, as well as the mode of integrating midwives into the maternity care system, that would promote the best outcomes and the autonomy of midwives. The research strategy involved a multiple-case study, in which each midwifery pilot project represented a case. Based on a qualitative approach, the study employed various sources of data: individual interviews and focus groups with key informants, site observations and analyses of written documents. Results show that midwives were poorly integrated into the health care system during the evaluation. Four main reasons were identified: lack of knowledge about the practice of midwifery on the part of other health care providers; deficiencies in the legal and organizational structure of the pilot projects; competition over professional territories; and gaps between the midwives' and other providers' professional cultures. Recommendations are provided to facilitate the integration of midwives into the health care system.

    Full Text Available Abstract Background The on call service for health protection in most parts of the UK is provided by general public health consultants, registrars and nurses as the first tier of response backed up by medical consultants in health protection. The first tier responder usually carries a large bag of papers containing both local and national guidance on the management of common cases/incidents. An electronic on call pack may provide a suitable practical alternative to large paper based systems and help professionals deliver out of hours health protection advice and response to incidents. Methods We developed and piloted an electronic on call pack in Hertfordshire for use at the health protection unit level containing key local and national guidelines, contact information and useful references. The on-call pack was initially piloted using a laptop and more recently using a personal digital assistant (PDA. The use of the on-call pack was evaluated. Results Key advantages of the electronic system include reduced size, faster access to information that is clearly indexed and the relative ease of updating information. As part of the pilot, the electronic on call pack was presented to a local and regional training meeting with good response from participants using qualitative and quantitative methods. Conclusion It is anticipated that with suitable evaluation this system can be adapted and utilised by other health protection practitioners. This system provides a fast, reliable and easily maintained source of information for the public health on-call team.

    An adaptive augmenting control algorithm for the Space Launch System has been developed at the Marshall Space Flight Center as part of the launch vehicles baseline flight control system. A prototype version of the SLS flight control software was hosted on a piloted aircraft at the Armstrong Flight Research Center to demonstrate the adaptive controller on a full-scale realistic application in a relevant flight environment. Concerns regarding adverse interactions between the adaptive controller and a proposed manual steering mode were investigated by giving the pilot trajectory deviation cues and pitch rate command authority. Two NASA research pilots flew a total of twenty five constant pitch-rate trajectories using a prototype manual steering mode with and without adaptive control.

    Full Text Available Abstract Background The ability to reduce inflammation in overweight and obese individuals may be valuable in preventing the progression to metabolic syndrome with associated risks for heart disease and diabetes. The purpose of this study was to evaluate the effect of multiple dosages of a proprietary Mangosteen Juice blend on indicators of inflammation and antioxidant levels in obese patients with elevated C-reactive protein (CRP levels. Methods The study was an 8 week randomized, double-blind, placebo-controlled study with a pre-study 2 week washout period. The study included four groups including placebo and three difference doses of the test product, XanGo Juice™: 3, 6 or 9 oz twice daily. The primary outcome measure of this study was high-sensitivity (HS-CRP. Secondary outcome measures included other biochemical indicators of inflammation, anthropomorphic measures and a safety evaluation. Results One hundred twenty two (122 persons were screened for the study, 44 were randomized and 40 completed the study. HS-CRP measurements dropped after 8 weeks treatment compared to baseline in all 3 dose groups and increased in the placebo group. The changes from baseline were not significant but the comparison of change from baseline was significant for the 18 oz group when compared to placebo (p = 0.02. Other markers of inflammation (inflammatory cytokines and a marker for lipid peroxidation (F2 isoprostane did not show any significant differences when compared with placebo. There was a trend towards a decrease in BMI in the juice groups. There were no side effects reported in any of the groups and none of the laboratory or EKG safety assessments indicated clinically significant changes for any subject.

    Full Text Available (1 Background: While the prevalence of tobacco smoking in the general population has declined, it remains exceptionally high for smokers with severe mental illness (SMI, despite significant public health measures. This project aims to adapt, pilot test and evaluate a novel e-health smoking cessation intervention to assist relapse prevention and encourage sustained smoking cessation for young adults (aged 18–29 years with SMI. (2 Methods: Using co-design principles, the researchers will adapt the Kick.it smartphone App in collaboration with a small sample of current and ex-smokers with SMI. In-depth interviews with smokers with SMI who have attempted to quit in the past 12 months and ex-smokers (i.e., those having not smoked in the past seven days will explore their perceptions of smoking cessation support options that have been of value to them. Focus group participants will then give their feedback on the existing Kick.it App and any adaptations needed. The adapted App will then be pilot-tested with a small sample of young adult smokers with SMI interested in attempting to cut down or quit smoking, measuring utility, feasibility, acceptability, and preliminary outcomes in supporting their quit efforts. (3 Conclusions: This pilot work will inform a larger definitive trial. Dependent on recruitment success, the project may extend to also include smokers with SMI who are aged 30 years or more.

    To develop a dietary self-management programme for salt-, fluid-, fat- and cholesterol-intake behaviours for older adults with low literacy and heart disease and evaluate the feasibility and acceptability of the programme. Eating behaviours such as fluid, salt, fat and cholesterol intake are an important factor related to heart disease outcomes. People with low literacy have difficulty following recommended health behaviours, but limited research has investigated intervention programmes for this population. Programme development and pilot testing its feasibility and acceptability. Recommendations were also collected from participants and the research assistant for future large-scale interventions. The study had two phases. Phase I consisted of programme development based on previous qualitative findings, a systematic review of the literature, clinical practice experience and expert opinion. In Phase II, we pilot tested the programme from January - June 2014 in a convenience sample of 10 older adults with low literacy, heart disease and recruited from a medical centre in northern Taiwan. Pilot testing showed that our programme was feasible and acceptable to older adults with low literacy and heart disease. Moreover, the final version of the programme was revised based on participants' and the research assistant's recommendations. Our study results suggest that with guidance and assistance, older adults with low literacy and heart disease can be motivated to take action for their health and are empowered by learning how to self-manage their heart-healthy eating behaviours. © 2016 John Wiley & Sons Ltd.

  8. Cluster Sampling Bias in Government-Sponsored Evaluations: A Correlational Study of Employment and Welfare Pilots in England.

    2016-01-01

    For pilot or experimental employment programme results to apply beyond their test bed, researchers must select 'clusters' (i.e. the job centres delivering the new intervention) that are reasonably representative of the whole territory. More specifically, this requirement must account for conditions that could artificially inflate the effect of a programme, such as the fluidity of the local labour market or the performance of the local job centre. Failure to achieve representativeness results in Cluster Sampling Bias (CSB). This paper makes three contributions to the literature. Theoretically, it approaches the notion of CSB as a human behaviour. It offers a comprehensive theory, whereby researchers with limited resources and conflicting priorities tend to oversample 'effect-enhancing' clusters when piloting a new intervention. Methodologically, it advocates for a 'narrow and deep' scope, as opposed to the 'wide and shallow' scope, which has prevailed so far. The PILOT-2 dataset was developed to test this idea. Empirically, it provides evidence on the prevalence of CSB. In conditions similar to the PILOT-2 case study, investigators (1) do not sample clusters with a view to maximise generalisability; (2) do not oversample 'effect-enhancing' clusters; (3) consistently oversample some clusters, including those with higher-than-average client caseloads; and (4) report their sampling decisions in an inconsistent and generally poor manner. In conclusion, although CSB is prevalent, it is still unclear whether it is intentional and meant to mislead stakeholders about the expected effect of the intervention or due to higher-level constraints or other considerations.

    One objective of the Kenya National Malaria Strategy 2009-2017 is scaling access to prompt diagnosis and effective treatment. In 2013, a quality assurance (QA) pilot was implemented to improve accuracy of malaria diagnostics at selected health facilities in low-transmission counties of Kenya. Trends in malaria diagnostic and QA indicator performance during the pilot are described. From June to December 2013, 28 QA officers provided on-the-job training and mentoring for malaria microscopy, malaria rapid diagnostic tests and laboratory QA/quality control (QC) practices over four 1-day visits at 83 health facilities. QA officers observed and recorded laboratory conditions and practices and cross-checked blood slides for malaria parasite presence, and a portion of cross-checked slides were confirmed by reference laboratories. Eighty (96%) facilities completed the pilot. Among 315 personnel at pilot initiation, 13% (n = 40) reported malaria diagnostics training within the previous 12 months. Slide positivity ranged from 3 to 7%. Compared to the reference laboratory, microscopy sensitivity ranged from 53 to 96% and positive predictive value from 39 to 53% for facility staff and from 60 to 96% and 52 to 80%, respectively, for QA officers. Compared to reference, specificity ranged from 88 to 98% and negative predictive value from 98 to 99% for health-facility personnel and from 93 to 99% and 99%, respectively, for QA officers. The kappa value ranged from 0.48-0.66 for facility staff and 0.57-0.84 for QA officers compared to reference. The only significant test performance improvement observed for facility staff was for specificity from 88% (95% CI 85-90%) to 98% (95% CI 97-99%). QA/QC practices, including use of positive-control slides, internal and external slide cross-checking and recording of QA/QC activities, all increased significantly across the pilot (p malaria QA/QC practices over the pilot.

    Full Text Available BACKGROUND: Different presentations of treatment effects can affect decisions. However, previous studies have not evaluated which presentations best help people make decisions that are consistent with their own values. We undertook a pilot study to compare different methods for doing this. METHODS AND FINDINGS: We conducted an Internet-based randomized trial comparing summary statistics for communicating the effects of statins on the risk of coronary heart disease (CHD. Participants rated the relative importance of treatment consequences using visual analogue scales (VAS and category rating scales (CRS with five response options. We randomized participants to either VAS or CRS first and to one of six summary statistics: relative risk reduction (RRR and five absolute measures of effect: absolute risk reduction, number needed to treat, event rates, tablets needed to take, and natural frequencies (whole numbers. We used logistic regression to determine the association between participants' elicited values and treatment choices. 770 participants age 18 or over and literate in English completed the study. In all, 13% in the VAS-first group failed to complete their VAS rating, while 9% of the CRS-first group failed to complete their scoring (p = 0.03. Different ways of weighting the elicited values had little impact on the analyses comparing the different presentations. Most (51% preferred the RRR compared to the other five summary statistics (1% to 25%, p = 0.074. However, decisions in the group presented the RRR deviated substantially from those made in the other five groups. The odds of participants in the RRR group deciding to take statins were 3.1 to 5.8 times that of those in the other groups across a wide range of values (p = 0.0007. Participants with a scientific background, who were more numerate or had more years of education were more likely to decide not to take statins. CONCLUSIONS: Internet-based trials comparing different presentations

    The burden of chronic pain is a major challenge, impacting the quality of life of patients. Intensive programmes of mindfulness-based therapy can help patients to cope with chronic pain but can be time consuming and require a trained specialist to implement. The self-management model of care is now integral to the care of patients with chronic pain; home-based interventions can be very acceptable, making a compelling argument for investigating brief, self-management interventions. The aim of this study is two-fold: to assess the immediate effects of a brief self-help mindfulness intervention for coping with chronic pain and to assess the feasibility of conducting a definitive randomized controlled trial to determine the effectiveness of such an intervention. A randomized controlled pilot study will be conducted to evaluate a brief mindfulness intervention for those with chronic pain. Ninety chronic pain patients who attend hospital outpatient clinics will be recruited and allocated randomly to either the control or treatment group on a 1:1 basis using the computer-generated list of random numbers. The treatment group receives mindfulness audios and the control group receives audios of readings from a non-fiction book, all of which are 15 minutes in length. Immediate effects of the intervention are assessed with brief psychological measures immediately before and after audio use. Mindfulness, mood, health-related quality of life, pain catastrophizing and experience of the intervention are assessed with standardized measures, brief ratings and brief telephone follow-ups, at baseline and after one week and one month. Feasibility is assessed by estimation of effect sizes for outcomes, patient adherence and experience, and appraisal of resource allocation in provision of the intervention. This trial will assess whether a brief mindfulness-based intervention is effective for immediately reducing perceived distress and pain with the side effect of increasing relaxation

    Full Text Available Introduction: Suicide is the second leading cause of death for the university aged population globally. A significant proportion of students with suicidal ideation or behaviours do not seek professional help. Few primary suicide prevention programs have specifically targeted help seeking for suicidal ideation or behaviours among university students. Methods: This study reported the development and pilot test of a brief, two-module online psychoeducational program (ProHelp that aimed to encourage help seeking for suicidal ideation and behaviours among university students. The program consists of two five-minute modules that address the risk factors and warning signs of suicide, stigmatising attitudes, and perceived barriers to help seeking. 156 Chinese university students and 101 Australian university students were recruited to evaluate the effectiveness of this program at post-test and one-month follow-up. Participants were randomly assigned to the psychoeducational program or an attention control program. Results: Of the Chinese and Australian students who were randomised into the study, around 50% completed the two­day post­test survey, and 30% completed the one-month follow­up survey. Although no significant difference was found between the control and experimental group on professional help-seeking beliefs and intentions, both groups' help-seeking attitudes increased during the study (p=0.003 for the post­test survey, and p=0.008 for the follow­up survey. The experimental group in both countries demonstrated a significant improvement in suicide literacy at the post-test survey (p=0.015 compared to control. Qualitative feedback indicated that the ProHelp program was user-friendly, clear, and helpful. Conclusions: This study provides initial evidence that a brief online psychoeducational program could enhance university students' suicide literacy in both China and Australia. It also suggests that increasing suicide literacy might not be

    A recurrent problem in information-systems development (ISD) is that many design shortcomings are not detected during development, but first after the system has been delivered and implemented in its intended environment. Pilot implementations appear to promise a way to extend prototyping from...... the laboratory to the field, thereby allowing users to experience a system design under realistic conditions and developers to get feedback from realistic use while the design is still malleable. We characterize pilot implementation, contrast it with prototyping, propose a iveelement model of pilot...... implementation and provide three empirical illustrations of our model. We conclude that pilot implementation has much merit as an ISD technique when system performance is contingent on context. But we also warn developers that, despite their seductive conceptual simplicity, pilot implementations can be difficult...

    The aim of this study was to evaluate the cost-effectiveness of a home-based palliative care model relative to usual care in expediting discharge or enabling patients to remain at home. Economic evaluation of a pilot randomised controlled trial with 28 days follow-up. Mean costs and effectiveness were calculated for the Palliative Care Extended Packages at Home (PEACH) and usual care arms including: days at home; place of death; PEACH intervention costs; specialist palliative care service use; acute hospital and palliative care unit inpatient stays; and outpatient visits. PEACH mean intervention costs per patient ($3489) were largely offset by lower mean inpatient care costs ($2450) and in this arm, participants were at home for one additional day on average. Consequently, PEACH is cost-effective relative to usual care when the threshold value for one extra day at home exceeds $1068, or $2547 if only within-study days of hospital admission are costed. All estimates are high uncertainty. The results of this small pilot study point to the potential of PEACH as a cost-effective end-of-life care model relative to usual care. Findings support the feasibility of conducting a definitive, fully powered study with longer follow-up and comprehensive economic evaluation.

    Anorectal malformations are often associated with rectal pouch fistulas. Surgical correction requires accurate evaluation of the presence and position of such fistulas. Fluoroscopy is currently the chosen modality for the detection of fistulas. The role of MRI is unexplored. To compare the diagnostic accuracy of MR versus fluoroscopic fistulography in the pre-operative evaluation of infants with anorectal malformation. We conducted a pilot study of infants requiring defunctioning colostomy for initial management of anorectal malformation. Dynamic sagittal steady-state free-precession MRI of the pelvis was acquired during introduction of saline into the mucous fistulas. Findings were compared among MR fistulography, fluoroscopic fistulography and intraoperative inspection. Eight children were included. Median age at fistulography was 15 weeks, inter-quartile range 13-20 weeks; all were boys. There was full agreement among MR fistulography, fluoroscopic fistulography and surgical findings. The pilot data suggest that MR fistulography is promising in the pre-operative evaluation of children with anorectal malformation. (orig.)

    A comparison of the sensitivity and intrusion of twenty pilot workload assessment techniques was conducted using a psychomotor loading task in a three degree of freedom moving base aircraft simulator. The twenty techniques included opinion measures, spare mental capacity measures, physiological measures, eye behavior measures, and primary task performance measures. The primary task was an instrument landing system (ILS) approach and landing. All measures were recorded between the outer marker and the middle marker on the approach. Three levels (low, medium, and high) of psychomotor load were obtained by the combined manipulation of windgust disturbance level and simulated aircraft pitch stability. Six instrument rated pilots participated in four seasons lasting approximately three hours each.

The Aviation Safety Reporting System data base is a compilation of voluntary reports of incidents from any person who has observed or been involved in an occurrence which was believed to have posed a threat to flight safety. This paper examines only those reported incidents specifically related to general aviation single-pilot IFR operations. The frequency of occurrence of factors related to the incidents was the criterion used to define significant problem areas and, hence, to suggest where research is needed. The data was cataloged into one of five major problem areas: (1) controller judgment and response problems, (2) pilot judgment and response problems, (3) air traffic control (ATC) intrafacility and interfacility conflicts, (4) ATC and pilot communication problems, and (5) IFR-VFR conflicts. In addition, several points common to all or most of the problems were observed and reported. These included human error, communications, procedures and rules, and work load.

    For pilot or experimental employment programme results to apply beyond their test bed, researchers must select 'clusters' (i.e. the job centres delivering the new intervention) that are reasonably representative of the whole territory. More specifically, this requirement must account for conditions that could artificially inflate the effect of a programme, such as the fluidity of the local labour market or the performance of the local job centre. Failure to achieve representativeness results ...

    The UH-60 BLACK HAWK was designed in the 1970s, when the US Army primarily operated during the day in good visual conditions. Subsequently, the introduction of night-vision goggles increased the BLACK HAWK'S mission effectiveness, but the accident rate also increased. The increased accident rate is strongly tied to increased pilot workload as a result of a degradation in visual cues. Over twenty years of research in helicopter flight control and handling qualities has shown that these degraded handling qualities can be recovered by modifying the response type of the helicopter in low speed flight. Sikorsky Aircraft Corporation initiated a project under the National Rotorcraft Technology Center (NRTC) to develop modern flight control laws while utilizing the existing partial authority Stability Augmentation System (SAS) of the BLACK HAWK. This effort resulted in a set of Modernized Control Laws (MCLAWS) that incorporate rate command and attitude command response types. Sikorsky and the US Army Aeroflightdynamics Directorate (AFDD) conducted a piloted simulation on the NASA-Ames Vertical h4otion Simulator, to assess potential handling qualities and to reduce the risk of subsequent implementation and flight test of these modern control laws on AFDD's EH-60L helicopter. The simulation showed that Attitude Command Attitude Hold control laws in pitch and roll improve handling qualities in the low speed flight regime. These improvements are consistent across a range of mission task elements and for both good and degraded visual environments. The MCLAWS perform better than the baseline UH-60A control laws in the presence of wind and turbulence. Finally, while the improved handling qualities in the pitch and roll axis allow the pilot to pay more attention to the vertical axis and hence altitude performance also improves, it is clear from pilot comments and altitude excursions that the addition of an Altitude Hold function would further reduce workload and improve overall

    In oil and gas industry, downhole pressure and temperature distributed sensors can provide strategic information for production optimization throughout the field. Upon the successful implementation of a pilot for optical fiber distributed temperature monitoring of observer wells in a steam injection field, two new pilots have been implemented to also monitor injectors and producers in both cyclic and continuous injection fields strongly influenced by H2S. The pilots demonstrated that this technology is suitable to monitor producers in onshore fields under the conditions above without risks to the production. The sensors did not prove to be suitable for long term monitoring of injectors under continuous steam injection if fiber is installed inside the injection tubing. For cyclic injection applications, the development of steam injection packers is needed to guarantee casing integrity during the injection cycle. The application of the technology in offshore wells is nowadays restricted to dry completion situation. The potential applicability in submarine wells is tightly linked to the development of downhole and wellhead wet mate optical fiber connectors. (author)

    Treatment decision-making is complex for people with multiple sclerosis. Profound information on available options is virtually not possible in regular neurologist encounters. The "nurse decision coach model" was developed to redistribute health professionals' tasks in supporting immunotreatment decision-making following the principles of informed shared decision-making. To test the feasibility of a decision coaching programme and recruitment strategies to inform the main trial. Feasibility testing and parallel pilot randomised controlled trial, accompanied by a mixed methods process evaluation. Two German multiple sclerosis university centres. People with suspected or relapsing-remitting multiple sclerosis facing immunotreatment decisions on first line drugs were recruited. Randomisation to the intervention (n = 38) or control group (n = 35) was performed on a daily basis. Quantitative and qualitative process data were collected from people with multiple sclerosis, nurses and physicians. We report on the development and piloting of the decision coaching programme. It comprises a training course for multiple sclerosis nurses and the coaching intervention. The intervention consists of up to three structured nurse-led decision coaching sessions, access to an evidence-based online information platform (DECIMS-Wiki) and a final physician consultation. After feasibility testing, a pilot randomised controlled trial was performed. People with multiple sclerosis were randomised to the intervention or control group. The latter had also access to the DECIMS-Wiki, but received otherwise care as usual. Nurses were not blinded to group assignment, while people with multiple sclerosis and physicians were. The primary outcome was 'informed choice' after six months including the sub-dimensions' risk knowledge (after 14 days), attitude concerning immunotreatment (after physician consultation), and treatment uptake (after six months).

    Full Text Available Objective structured clinical examination (OSCE is an effective assessment method to evaluate medical students' clinical competencies performance. Postgraduate year 1 (PGY1 residents have been initiated in a general medicine training program in Taiwan since 2003. However, little is known about the learning effectiveness of trainees from this program. This pilot study aimed to evaluate the clinical core competencies of PGY1 residents using OSCE, and to reflect on the strengths and weaknesses of this pilot assessment project. OSCE was conducted for five PGY1 examinees (4 men, 1 woman with five stations covering core themes, including history taking, physical examination, clinical procedure of airway intubation, clinical reasoning, and communication skills for informing bad news. Itemized checklists and five-point Likert scale global ratings were used for evaluating performance. The results showed that the performance of our PGY1 residents on history taking was significantly better after about 2 months of postgraduate training on general internal medicine. Self-evaluation on performance by examinees revealed significantly lower global ratings on post-course OSCE (4.14 ± 0.80 vs. 3.68 ± 0.66; p < 0.02. Surveys from tutors and standardized patients (SPs completed at pre- and post-course OSCEs showed consistently favorable responses on the purposes, content, process, and environment of this assessment (4.0 ± 0.17 vs. 4.0 ± 0.12, nonsignificant. However, a survey of the examinees completed at preand post-course OSCEs showed relatively unfavorable responses to the same aspects, and to tutors and SPs (4.1 ± 0.09 vs. 3.7 ± 0.18; p < 0.05. Qualitative information revealed that tutors and SPs remarked that PGY1 residents' medical knowledge performance was satisfactory but their clinical reasoning performance, communication skills (giving bad news and self-confidence were unsatisfactory. In conclusion, this pilot study has demonstrated that OSCE is a

    This action research is an ongoing study which will last from 1991 to 1993. The main purpose of the study is to increase the participation of informal caregivers in the hospital care of elderly patients without decreasing the quality of care. The data reported here are from a pilot study. This study had three aims: (a) to test reliability and validity of the measure used, (b) to investigate the current participation of informal caregivers in the hospital care of elderly patients (aged over 75), and (c) to evaluate and compare the quality of care from both the patients' and the informal caregivers' point of view in three different hospitals. The measure of quality of care was developed on the basis of need theories, mainly those of Maslow and Alderfer. Patients and caregivers were also asked to rate the participation of the caregivers in the hospital care of elderly patients. Participation consisted of 18 activities of daily living. The pilot test with 18 elderly hospital patients and seven family members or significant others showed differences between the two groups in perception of care received. Statistically significant differences (P needs, psychic and spiritual needs and totals. The results supported earlier findings that elderly patients are satisfied with and do not criticize their care. The younger generation (i.e. their children) is more demanding and has precise perceptions about the care given. Relatives could be used more in planning, evaluation and even implementation of care; however, their current participation in patient hospital care is minimal.

    Recruitment to randomised controlled trials (RCTs) is a perennial problem. Calls have been made for trialists to make recruitment performance publicly available. This article presents our experience of recruiting to a pilot RCT of cardiac rehabilitation for patients with bowel cancer with an embedded process evaluation. Recruitment took place at three UK hospitals. Recruitment figures were based on the following: i) estimated number of patient admissions, ii) number of patients likely to meet inclusion criteria from clinician input and iii) recruitment rates in previous studies. The following recruitment procedure was used:Nurse assessed patients for eligibility.Patients signed a screening form indicating interest in and agreement to be approached by a researcher about the study.An appointment was made at which the patient signed a consent form and was randomised to the intervention or control group. Information about all patients considered for the study and subsequently included or excluded at each stage of the recruitment process and reasons given were recorded. There were variations in the time taken to award Research Management approval to run the study at the three sites (45-359 days). Sixty-two percent of the original recruitment estimate was reached. The main reason for under-recruitment was due to over-estimation of the number of patient admissions; other reasons were i) not assessing all patients for eligibility, ii) not completing a screening form for eligible patients and iii) patients who signed a screening form being lost to the study before consenting and randomisation. Pilot trials should not simply aim to improve recruitment estimates but should also identify factors likely to influence recruitment performance in a future trial and inform the development of that trial's recruitment strategies. Pilot trials are a crucial part of RCT design. Nevertheless, pilot trials are likely to be small scale, involving only a small number of sites, and

    The ethanol industry has grown rapidly during the past ten years, mainly due to increasing oil prices. However, efficient and cost-effective solutions for treating thin stillage wastewater have still to be developed. The anaerobic membrane bioreactor (AnMBR) technology combines classical anaerobic treatment in a completely-stirred tank reactor (CSTR) with membrane separation. The combination of these two technologies can achieve a superior effluent quality and also increase biogas production compared to conventional anaerobic solutions. A pilot-scale AnMBR treating thin stillage achieved very high treatment efficiencies in terms of chemical oxygen demand (COD) and total suspended solids (TSS) removal (>98%). An average permeate flux of 4.3 L/m2 x h was achieved at relatively low transmembrane pressure (TMP) values (0.1-0.2 bars) with flat-sheet membranes. Experience gained during the pilot-scale studies provides valuable information for scaling up of AnMBRs treating complex and high-strength wastewaters.

    Previous studies have described refinery plugging caused by volatile phosphorus components originating from phosphate ester oil gellants as well as two successful field trials of new phosphonate ester oil gellants, which were demonstrated to address this problem. Additional field testing of phosphonate ester gellants directed at optimization of cost and performance has also been previously studied. This paper presented the results of a follow-up study to these previous investigations, as new modified phosphate ester systems were expected to become commercial that would reduce volatile phosphorus. Several questions that required further investigation were discussed in this paper. These included the comparative ability of phosphonate and modified phosphate esters to control volatile phosphorus; tower fouling at higher temperatures in the presence of steam; and, organic halide formations under distillation tower conditions. The paper presented the results of full-scale pilot plant testing that was performed over several days with flowback captured after actual fracturing treatments in order to serve as a guide to the selection of oil gellant systems for reduction of refinery tower and heat exchanger fouling. The study measured fouling of a tray inserted in the pilot plant distillation tower as well as fouling of the packing material. Any changes in operating parameters such as rate, temperature, or pressure over the time of each test were also noted, as these could also be indicative of fouling. 3 refs., 2 tabs., 17 figs.

    The manufacturers for gamma camera systems and their distribution organisations in Germany, ADAC, Elscint, Gaede, General Electric, Picker, Siemens, Sopha and Toshiba initiated in cooperation with the Central Association of the Electro and Electronic Industry (Zentralverband der Elektro-und Elektronikindustrie eV, ZVEl), a pilot study to test whether the clinical computer programs for the calculation of the Technetium-99m-Mag 3 Clearance according Bubeck deliver comparable results. For this purpose three dynamic scintigraphic renal studies were converted to interfile format and were sent to the firms at two occasions including blood sampling data and anonymousized patient information. The results were returned to the SAM GmbH System Analysen in der Medizin (Bad Oeynhausen) and analyzed. All of the eight participating firms except one calculated correct clearance values. The reason for the failure in one case turned out to be a bug in the computer program. This pilot study has demonstrated that it is possible to establish certain technical standards for the clinical software in nuclear medicine but also to detect and correct errors. (orig.) [de

    Little is known about how best to implement portfolio-based learning in medical school. We evaluated the introduction of a formative e-portfolio-based supervision pilot for final year medical students by seeking views of students, supervisors and graduates on use and educational effects. Students and supervisors were surveyed by questionnaire, with free text comments invited. Interviews were held with new graduates in their first Foundation Programme placement. Most students used the e-portfolio (54%) and met with their supervisor (62%) 'once or twice' only. Students had more negative views: 22% agreed that the pilot was beneficial, while most supervisors thought that e-portfolio (72%) and supervision (86%) were a 'good idea'. More students reported supervision meetings benefited learning (49%) and professional development (55%) than the e-portfolio did (16%; 28%). Only 47% of students felt 'prepared' for future educational processes, though graduates noted benefits for navigating and understanding e-portfolio building and supervision. Factors limiting engagement reflected 'burden', while supervision meetings and early experience of postgraduate processes offered educational value. Final year students have negative attitudes to a formative e-portfolio, though benefits for easing the educational transition are recognised by graduates. Measures to minimize time, repetition and redundancy of processes may encourage use. Engagement is influenced by the supervisor relationship and educational value may be best achieved by supporting supervisors to develop strategies to facilitate, and motivate self-directed learning processes in undergraduates.

    The 'Healthy Habits Program' is a 6-month community-based program, which offers exercise facilities, training and weekly health education group to underserved elderly Chinese Americans with chronic medical diseases in their native languages. This pilot study evaluates the acceptability and the health effects of the 'Healthy Habits Program'. Ninety-nine subjects participated in the 'Healthy Habits Program' in 2011. Before and after the program, the participants were assessed in their physical and mental health using various fitness tests as well as measures of disability and psychological functioning. Participants provided overwhelmingly positive feedback on the program, which was associated with significant improvements in physical and mental health including a significant decrease in body mass index (BMI), blood pressure and increase in stamina. The participants reported lower mean scores on the Patient Health Questionnaire-9 item Scale (PHQ-9), indicating improved psychological well-being. These promising pilot study results from this lifestyle intervention program for elderly Chinese American immigrants with chronic diseases inform the design of a more definitive trial using a randomized design and larger sample size.

    Simulation is frequently being used as a learning and teaching resource for both undergraduate and postgraduate students, however reporting of the effectiveness of simulation particularly within the pharmacology context is scant. The aim of this pilot study was to evaluate a filmed simulated pharmacological clinical scenario as a teaching resource in an undergraduate pharmacological unit. Pilot cross-sectional quantitative survey. An Australian university. 32 undergraduate students completing a healthcare degree including nursing, midwifery, clinical science, health science, naturopathy, and osteopathy. As a part of an undergraduate online pharmacology unit, students were required to watch a filmed simulated pharmacological clinical scenario. To evaluate student learning, a measurement instrument developed from Bloom's cognitive domains (knowledge, comprehension, application, analysis, synthesis and evaluation) was employed to assess pharmacological knowledge conceptualisation and knowledge application within the following fields: medication errors; medication adverse effects; medication interactions; and, general pharmacology. The majority of participants were enrolled in an undergraduate nursing or midwifery programme (72%). Results demonstrated that the majority of nursing and midwifery students (56.52%) found the teaching resource complementary or more useful compared to a lecture although less so compared to a tutorial. Students' self-assessment of learning according to Bloom's cognitive domains indicated that the filmed scenario was a valuable learning tool. Analysis of variance indicated that health science students reported higher levels of learning compared to midwifery and nursing. Students' self-report of the learning benefits of a filmed simulated clinical scenario as a teaching resource suggest enhanced critical thinking skills and knowledge conceptualisation regarding pharmacology, in addition to being useful and complementary to other teaching and

    In this pilot study we wanted to evaluate the kinematics of a knee implanted with an artificial polycarbonate-urethane meniscus device, designed for medial meniscus replacement. The static kinematic behavior of the implant was compared to the natural medial meniscus of the non-operated knee. A second goal was to evaluate the motion pattern, the radial displacement and the deformation of the meniscal implant. Three patients with a polycarbonate-urethane implant were included in this prospective study. An open-MRI was used to track the location of the implant during static weight-bearing conditions, within a range of motion of 0° to 120° knee flexion. Knee kinematics were evaluated by measuring the tibiofemoral contact points and femoral roll-back. Meniscus measurements (both natural and artificial) included anterior-posterior meniscal movement, radial displacement, and meniscal height. No difference (P>0.05) was demonstrated in femoral roll-back and tibiofemoral contact points during knee flexion between the implanted and the non-operated knees. Meniscal measurements showed no significant difference in radial displacement and meniscal height (P>0.05) at all flexion angles, in both the implanted and non-operated knees. A significant difference (P ≤ 0.05) in anterior-posterior movement during flexion was observed between the two groups. In this pilot study, the artificial polycarbonate-urethane implant, indicated for medial meniscus replacement, had no influence on femoral roll-back and tibiofemoral contact points, thus suggesting that the joint maintains its static kinematic properties after implantation. Radial displacement and meniscal height were not different, but anterior-posterior movement was slightly different between the implant and the normal meniscus. Copyright © 2014 Elsevier Ltd.

    Full Text Available Background and context: A key role of the district’s Nursing Midwifery Practice and Workforce Unit is to build capability in the nursing and midwifery workforce. In this paper I reflect on the experience of my team following attendance at a two-day Coaching for Performance workshop and the impact this had on developing coaching skills for nurse managers and nurse unit managers in South Eastern Sydney Local Health District. Aims: To highlight how engaging in critical reflection enabled the unit team to identify gaps in the transfer of coaching skills learned from the two-day workshop to everyday management practices. The pilot project to embed coaching into management practices is the result of the team’s reflection. The method, findings and implications for coaching practices for nurse managers and nurse unit managers are described in detail. Findings: Using Gibbs’ model of reflection, the unit team reflected on its collective experiences following attendance at the workshop. This led to the development of a pilot coaching project called Embedding Coaching into Practice for nurse managers and nurse unit managers, which enabled the transfer of coaching skills learned to everyday management practices. The pilot project used a ‘coaching the coach’ approach, with structured follow-up at the managers’ places of work. This had a positive impact on the development of coaching skills and managers were able to use these skills with confidence to enable their staff to develop problem-solving skills. Conclusions: This paper highlights how using a validated tool for reflection can lead to positive change. ‘Coaching the coach’ can support transfer of coaching skills learned into everyday practices, which has a positive impact on work performance for nurse managers, nurse unit managers and their staff. It supports the practice development principle that lifelong learning can influence effective workplace cultures and have a positive impact on

    Nearly 2 million children in the United States have a parent in prison. The circumstances related to this situation place them at increased risk for behavioral and emotional disorders. The process of reunification between mother and child after release is a stressful and emotional one. A pilot study was conducted to develop and test a new program, Emotions: Taking Care of Yourself and Your Child When You Go Home. The objective of the Emotions Program was to teach emotion regulation and emotion coaching skills to incarcerated mothers so as to assist mothers and their children to cope better with the stress associated with incarceration and the transition home from prison. Pilot participants (N = 47) had previously participated in Parenting Inside Out, an evidence-based parenting program for incarcerated parents. The participants were then assigned to the Emotions Program (n = 29) or the comparison condition of no additional treatment (n = 18). All mothers were assessed before (T1) and after the program (T2), and again 6 months after release from prison (T3). Intervention effects of the Emotions Program on mothers’ emotion regulation, emotion socialization, and adjustment were examined using repeated-measures analysis of variance with a between-subjects factor of group (Emotions Program vs. comparison) and a within-subjects factor of time (T1 vs. T2 vs. T3). Moderate time by group interaction effects were observed for aspects of emotion regulation, emotion socialization behavior, and criminal behavior in mothers, with participants in the Emotions condition showing improvement relative to those in the comparison condition.

    This article describes an innovative initiative to support partnership working between trade unions and management in three National Health Service Trusts, by means of shared participation in a series of learning and development days. Although there is existing evidence, within the literature on partnership, of the benefits of partnership working for employees and employers, there is little discussion of processes by which effective partnership is developed. More specifically, there is no current academic literature on the role of education in enabling improved partnership working between trade unions and managers. The findings of the evaluation suggest that the pilot provided a successful learning experience as well as a number of pointers for improving future developments of this nature. The recommendations include embedding of partnership work within existing staff development processes. Copyright © 2011 Elsevier Ltd. All rights reserved.

    Prevention interventions for people living with HIV/AIDS are an important component of HIV programs. We report the results of a pilot evaluation of a four-hour, clinic-based training for healthcare providers in South Africa on HIV prevention assessments and messages. This pre/post pilot evaluation examined whether the training was associated with providers delivering more prevention messages. Seventy providers were trained at four public primary care clinics with a high volume of HIV patients. Pre- and post-training patient exit surveys were conducted using Audio-Computer Assisted Structured Interviews. Seven provider appropriate messaging outcomes and one summary provider outcome were compared pre- and post-training using Poisson regression. Four hundred fifty-nine patients pre-training and 405 post-training with known HIV status were interviewed, including 175 and 176 HIV positive patients respectively. Among HIV positive patients, delivery of all appropriate messages by providers declined post-training. The summary outcome decreased from 56 to 50%; adjusted rate ratio 0.92 (95% CI = 0.87-0.97). Sensitivity analyses adjusting for training coverage and time since training detected fewer declines. Among HIV negative patients the summary score was stable at 32% pre- and post-training; adjusted rate ratio 1.05 (95% CI = 0.98-1.12). Surprisingly, this training was associated with a decrease in prevention messages delivered to HIV positive patients by providers. Limited training coverage and delays between training and post-training survey may partially account for this apparent decrease. A more targeted approach to prevention messages may be more effective.

    This multicenter, open-label pilot study evaluated safety, efficacy and tolerability of a topical formulation containing a multipotent growth factor resignaling complex (MRCx), when applied to infraorbital and lateral canthal skin. Thirty-nine female subjects with mean age of 56.8 years who had periorbital lines and wrinkles, uneven skin texture, puffiness, and lack of skin firmness were enrolled, and 38 completed the study. All subjects applied the multipotent growth factor formulation bilaterally to the periorbital area, twice daily for 60 days. Efficacy and treatment-related adverse events were evaluated at Baseline and days 14, 30, and 60. Investigators rated the periorbital areas based on 10-point scales. Subjects' self-reported compliance with treatment was greater than 99% throughout the study. At day 60, all subjects had improvement in infraorbital brightness (≥ 2 points), moistness (≥ 2 points), wrinkles (≥ 1 point), sallowness (≥ 1 point), crepiness (≥ 1 point), smooth texture (≥ 1 point), skin tightness (≥ 1 point), and skin tone (≥ 1 point). Investigator-rated assessments showed ≥ 1-point improvement for lateral canthal wrinkles, dyschromia/mottled pigmentation, skin tone, overall brightness, and moistness. Investigator-rated scoring on the Global Aesthetic Improvement Scale (GAIS) demonstrated that 67.6% of subjects were much improved/improved at day 14, and 63.1% remained improved at day 60. Overall, 76.2% and 79.0% of subjects were very pleased/pleased/mostly pleased with the appearance of their infraorbital and lateral canthal areas at day 60. Adverse events comprised one case of mild canthal erythema, and one case of mild eye irritation, both of which were respectively resolved. This pilot study demonstrated that the topical multipotent growth factor formulation was safe, effective and well tolerated for periorbital skin rejuvenation.

    To date, the limited degrees of freedom (DOF) of most robotic training devices hinders them from providing functional training following stroke. We developed a 6-DOF exoskeleton ("BONES") that allows movement of the upper limb to assist in rehabilitation. The objectives of this pilot study were to evaluate the impact of training with BONES on function of the affected upper limb, and to assess whether multijoint functional robotic training would translate into greater gains in arm function than single joint robotic training also conducted with BONES. Twenty subjects with mild to moderate chronic stroke participated in this crossover study. Each subject experienced multijoint functional training and single joint training three sessions per week, for four weeks, with the order of presentation randomized. The primary outcome measure was the change in Box and Block Test (BBT). The secondary outcome measures were the changes in Fugl-Meyer Arm Motor Scale (FMA), Wolf Motor Function Test (WMFT), Motor Activity Log (MAL), and quantitative measures of strength and speed of reaching. These measures were assessed at baseline, after each training period, and at a 3-month follow-up evaluation session. Training with the robotic exoskeleton resulted in significant improvements in the BBT, FMA, WMFT, MAL, shoulder and elbow strength, and reaching speed (p robotic training programs. However, for the BBT, WMFT and MAL, inequality of carryover effects were noted; subsequent analysis on the change in score between the baseline and first period of training again revealed no difference in the gains obtained between the types of training. Training with the 6 DOF arm exoskeleton improved motor function after chronic stroke, challenging the idea that robotic therapy is only useful for impairment reduction. The pilot results presented here also suggest that multijoint functional robotic training is not decisively superior to single joint robotic training. This challenges the idea that

    Computer assisted instruction (CAI) is an effective tool for evaluating and training students and professionals. In this article we will present a learning-oriented CAI, which has been developed for students and health professionals to acquire and retain new knowledge through the practice. A two-phase pilot evaluation was conducted, involving 8 nutrition experts and 30 postgraduate students, respectively. In each training session, the software developed guides users in the integral evaluation of a patient's nutritional status and helps them to implement actions. The program includes into the format clinical tools, which can be used to recognize possible patient's needs, to improve the clinical reasoning and to develop professional skills. Among them are assessment questionnaires and evaluation criteria, cardiovascular risk charts, clinical guidelines and photographs of various diseases. This CAI is a complete software package easy to use and versatile, aimed at clinical specialists, medical staff, scientists, educators and clinical students, which can be used as a learning tool. This application constitutes an advanced method for students and health professionals to accomplish nutritional assessments combining theoretical and empirical issues, which can be implemented in their academic curriculum.

    The real-life practice of 'healing' for cancer in the community as perceived by clients and healers was investigated in a multi-method pilot study. Fifteen clients received six weekly healing sessions. Pre- and post-changes in perception towards well-being and client experience were assessed by EuroQol (EQ-5D), measure yourself concerns and well-being (MYCaW) and a client satisfaction tool. Qualitative methods, including focus groups, explored the perceived effects of healing in more depth and the participants' experience of taking part in research. The study was not designed to test the effect of healing on disease. Quantitative data showed perceived significant improvements in 'concerns/problems' for which clients wanted help (pquantitative improvements to healing itself. Despite some concerns, healers and clients engaged fully with the research process, and were enthusiastic about the importance of research into healing. Our study suggests that, while there are some confounding issues and study limitations to address, clients and healers perceive healing to have a range of benefits, particularly in terms of coping with cancer, and regard it as a useful approach that can be applied in a community setting alongside conventional medicine.

    2015-06-01

    Full Text Available The Escola Tècnica Superior d’Enginyeria Química has a long tradition in the deployment of social competencies in engineering curricula through Integrated Projects (IP carried out in structured teams. Social competencies are taught and practiced during the development of the IPs. We conceptually introduce a methodology for a 360o assessment of the students’ social competencies, as a tool to foster the improvement of their competency levels. In this article we analyze the results of the pilot test where the aforementioned methodology has been implemented in the Bachelor studies of Chemical Engineering. The results indicate that it is possible to objectively obtain the student’s competency level discriminating among different social competencies, as well as among different students in the same team. The application of this tool fosters the development of specific educative actions to help the students with low competency profile, to reach acceptable levels for a successful insertion in the labor market.

    2018-01-01

    This study aimed to examine the effectiveness of The Enhanced Support Service (ESS) pilot in reducing custodial violence and disruption, and the associated costs, by observing the behavioural change of the 35 service users who participated in ESS intervention within its first 22 months of operation. Frequencies of recorded incidents of aggressive behaviours, self-harming behaviours, noncompliance, and positive behaviours were counted from routine administrative systems using a coding structure developed in previous studies. The count data were analysed using nonparametric tests and Poisson regression models to derive an Incident Rate Ratio (IRR). Findings suggest the ESS is associated with a reduction in aggressive behaviours and noncompliance, with medium to large effect sizes ( r = .31-.53); however, it was not associated with a reduction in deliberate self-harm or increased positive behaviours. The Poisson models revealed that levels of pre-intervention behaviour, intervention length, intervention completion, and service location had varying effects on postintervention behaviour, with those who completed intervention demonstrating more favourable outcomes. The ESS service model was associated with a reduction in behaviour that challenges, which has implications for the reduction in associated social, economic, and political costs-as well as the commissioning of interventions and future research in this area.

    The duration of the antiemetic effect of granisetron was examined in a pilot study of patients (n = 26) undergoing a standard emetogenic stimulus in the form of total body irradiation fractionated over 3-4 days, in a randomized comparison with twice-daily ondansetron. A single intravenous dose of granisetron at the onset of therapy was effective over the entire follow-up period in 50% (6/12) of patients, compared with 77% (10/13) prescribed twice-daily oral ondansetron for 3 or 4 days. The response rate within the first 24 hours from the start of irradiation was 67% (8/12) for granisetron and 77% (10/13) for ondansetron. Granisetron and ondansetron was therefore of similar efficacy within the first 24-hour period, but granisetron was less efficaceous more than 24 hours after the onset of therapy. Patients who required a second dose of granisetron did so at intervals of 12, 42, 47 and 48 hours following the first fraction of radiotherapy. The cost per patient in this study was 48 for granisetron and {sub 1}54 for ondanestron, but the dose scheduling we used cannot be recommended in view of the lower effectiveness of granisetron.

    2016-06-01

    Full Text Available This paper gives an overview of the new COmpact hyperSpectral Imaging (COSI system recently developed at the Flemish Institute for Technological Research (VITO, Belgium and suitable for remotely piloted aircraft systems. A hyperspectral dataset captured from a multirotor platform over a strawberry field is presented and explored in order to assess spectral bands co-registration quality. Thanks to application of line based interference filters deposited directly on the detector wafer the COSI camera is compact and lightweight (total mass of 500g, and captures 72 narrow (FWHM: 5nm to 10 nm bands in the spectral range of 600-900 nm. Covering the region of red edge (680 nm to 730 nm allows for deriving plant chlorophyll content, biomass and hydric status indicators, making the camera suitable for agriculture purposes. Additionally to the orthorectified hypercube digital terrain model can be derived enabling various analyses requiring object height, e.g. plant height in vegetation growth monitoring. Geometric data quality assessment proves that the COSI camera and the dedicated data processing chain are capable to deliver very high resolution data (centimetre level where spectral information can be correctly derived. Obtained results are comparable or better than results reported in similar studies for an alternative system based on the Fabry–Pérot interferometer.

    Full Text Available Introduction. Several studies in pediatric trauma care have demonstrated substantial deficits in both prehospital and emergency department management. Methods. In February 2015 the PAEDSIM collaborative conducted a one and a half day interdisciplinary, simulation based team-training course in a simulated pediatric emergency department. 14 physicians from the medical fields of pediatric surgery, pediatric intensive care and emergency medicine, and anesthesia participated, as well as four pediatric nurses. After a theoretical introduction and familiarization with the simulator, course attendees alternately participated in six simulation scenarios and debriefings. Each scenario incorporated elements of pediatric trauma management as well as Crew Resource Management (CRM educational objectives. Participants completed anonymous pre- and postcourse questionnaires and rated the course itself as well as their own medical qualification and knowledge of CRM. Results. Participants found the course very realistic and selected scenarios highly relevant to their daily work. They reported a feeling of improved medical and nontechnical skills as well as no uncomfortable feeling during scenarios or debriefings. Conclusion. To our knowledge this pilot-project represents the first successful implementation of a simulation-based team-training course focused on pediatric trauma care in German-speaking countries with good acceptance.

    In this study, continuous operation of a pilot-scale upflow anaerobic sludge blanket (UASB) reactor for sewage treatment was conducted for 630 days to investigate the physical and microbial characteristics of the retained sludge. The UASB reactor with a working volume of 20.2 m(3) was operated at ambient temperature (16-29 °C) and seeded with digested sludge. After 180 days of operation, when the sewage temperature had dropped to 20 °C or lower, the removal efficiency of both total suspended solids (TSS) and total biochemical oxygen demand (BOD) deteriorated due to washout of retained sludge. At low temperature, the cellulose concentration of the UASB sludge increased owing to the rate limitation of the hydrolytic reaction of suspended solids in the sewage. However, after an improvement in sludge retention (settleability and concentration) in the UASB reactor, the process performance stabilized and gave sufficient results (68% of TSS removal, 75% of total BOD removal) at an hydraulic retention time (HRT) of 9.7 h. The methanogenic activity of the retained sludge significantly increased after day 246 due to the accumulation of Methanosaeta and Methanobacterium following the improvement in sludge retention in the UASB reactor. Acid-forming bacteria from phylum Bacteroidetes were detected at high frequency; thus, these bacteria may have an important role in suspended solids degradation.

    This pilot study assesses the impact of FREED (First Episode Rapid Early Intervention for Eating Disorders [ED]), a novel transdiagnostic service for emerging adults with recent ED onset, on clinical outcomes. Data were collected from 56 patients and 19 carers for 12 months following enrolment. FREED patients showed significant improvements in ED and other symptoms across time. Carers also showed psychological improvements. For FREED anorexia nervosa (AN) patients, body mass index (BMI) at initial clinical assessment was similar to that of comparable patients (audit cohort) seen in our service before (16.4 vs 16.1 kg/m 2 ). By start of treatment, because of their shorter wait, FREED-AN had gained weight whereas audit patients had lost (16.7 vs 15.8 kg/m 2 ). This difference continued throughout treatment, and at 12 months, nearly 60% FREED-AN patients returned to a BMI of 18.5 or greater. FREED shows promise as a service model for emerging adults with EDs. Copyright © 2018 John Wiley & Sons, Ltd and Eating Disorders Association.

    Eighteen nonradioactive defense high-level waste (DHLW) canisters were emplaced in and subjected to accelerated overtest thermal conditions for about three years at the bedded salt Waste Isolation Pilot Plant (WIPP) facility. Post-test laboratory corrosion results of several stainless steel 304L waste canisters, cast steel overpacks, and associated instruments ranged from negligible to moderate. We found appreciable surface corrosion and corrosion products on the cast steel overpacks. Pieces of both 304L and 316 stainless steel test apparatus underwent extensive stress-corrosion cracking failure and nonuniform attack. One of the retrieved test packages contained nonradioactive glass waste form from the Savannah River Site. We conducted post-test analyses of this glass to determine the degree of resultant glass fracturing, and whether any respirable fines were present. Linear glass fracture density ranged from about 1 to 8 fractures intersecting every 5 cm (2 inch) segment along a diameter line of the canister cross-section. Glass fines between 1 and 10 microns in diameter were detected, but were not quantified

    2016-09-01

    The overall objective of this project is to achieve the DOE’s goal to develop advanced CO2 capture and separation technologies that can realize at least 90% CO2 removal from flue gas steams produced at a pulverized coal (PC) power plant at a cost of less than $40/tonne of CO2 captured. The principal objective is to test a CO2 capture process that will reduce the parasitic plant load by using a CO2 capture sorbent that will require a reduced amount of steam. The process is based on advanced carbon sorbents having a low heat of adsorption, high CO2 adsorption capacity, and excellent selectivity. While the intent of this project was to produce design and performance data by testing the sorbent using a slipstream of coal-derived flue gas at the National Carbon Capture Center (NCCC) under realistic conditions and continuous long-term operation, the project was terminated following completion of the detailing pilot plant design/engineering work on June 30, 2016.

    The mutagenicity of indoor air paniculate matter has been measured in a pilot field study of homes in Columbus, Ohio during the 1984 winter. The study was conducted in eight all natural-gas homes and two all electric homes. Paniculate matter and semi-volatile organic compounds were collected indoors using a medium volume sampler. A micro-forward mutation bioassay employing Salmonella typhimurium strain TM 677 was used to quantify the mutagenicity in solvent extracts of microgram quantities of indoor air particles. The mutagenicity was quantified in terms of both mutation frequency per mg of organic matter extracted and per cubic meter of air sampled. The combustion source variables explored in this study included woodburning in fireplaces and cigarette smoking. Homes in which cigarette smoking occurred had the highest concentrations of mutagenicity per cubic meter of air. The average indoor air mutagenicity per cubic meter was highly correlated with the number of cigarettes smoked. When the separate sampling periods in each room were compared, the mutagenicity in the kitchen samples was the most highly correlated with the number of cigarettes smoked.

    The purpose of this study was to examine implementation processes in elementary classrooms during a 2-year (Fall 2014 to Spring 2016) pilot intervention program, Partnerships for Active Children in Elementary Schools (PACES). We examined (a) the effect of PACES on the extent of movement integration (MI) and (b) changes in teachers' perceptions regarding MI. Purposively selected classrooms (grades 1-3) across four schools (3 intervention, 1 control) participated in the study. The sample included classroom teachers (N = 12) in Fall 2014 and Spring 2015, but the number of participants dropped to eight in Fall 2015 and Spring 2016. PACES consisted of three partnership approaches (a virtual community of practice, community-based participatory research, and university service learning) intended to increase the extent of MI in the intervention classrooms. We collected process data using the System for Observing Student Movement in Academic Routines and Transitions (SOSMART) and teacher interviews. PACES did not significantly impact the extent of observed MI. Interviews indicated that the intervention had both strengths and limitations. Building interpersonal support for teachers is important to their use of MI. A different measurement schedule (e.g., collecting MI data each day of the school week) may be required to more thoroughly capture MI instances. Copyright © 2018 Elsevier Ltd. All rights reserved.

    In this pilot study, an autologous synthetic scaffold-free construct with hyaline quality, termed living hyaline cartilaginous graft (LhCG), was applied for treating cartilage lesions. Implantation of autologous LhCG was done at load-bearing regions of the knees in skeletally mature mini-pigs for 6 months. Over the course of this study, significant radiographical improvement in LhCG treated sites was observed via magnetic resonance imaging. Furthermore, macroscopic repair was effected by LhCG at endpoint. Microscopic inspection revealed that LhCG engraftment restored cartilage thickness, promoted integration with surrounding native cartilage, produced abundant cartilage-specific matrix molecules, and re-established an intact superficial tangential zone. Importantly, the repair efficacy of LhCG was quantitatively shown to be comparable to native, unaffected cartilage in terms of biochemical composition and biomechanical properties. There were no complications related to the donor site of cartilage biopsy. Collectively, these results imply that LhCG engraftment may be a viable approach for articular cartilage repair.

    To determine if a pilot phase workshop influenced residents' beliefs and concerns about using opioids for chronic noncancer pain. Pre- and post-survey questionnaire. University residency program. Seventy-two Medicine and Medicine-Pediatrics residents. Participation in a 4-hour workshop based on adult learning theory. Residents' pre- and post-workshop concerns, feelings, and beliefs about the efficacy and safety of opioids for chronic noncancer pain (low back pain), and barriers to prescribing them (paired t-tests). On a scale of 1 = least to 10 = most, residents' concerns about addiction risk from opioids in patients with chronic noncancer pain dropped significantly (P changes were observed regarding concerns about abuse (5.61 to 3.92), side effects (4.88 to 2.88), limiting use of other treatments (5.41 to 3.60), sanctioning (State Board; 4.27 to 3.71; Legal 4.22 to 3.43), and drawing criticism from attending staff (4.50 to 2.77), with P beliefs about efficacy and safety of opioids for chronic noncancer pain increased (Pre 4.96 to Post 7.40), and they were more comfortable prescribing them (4.30 to 6.82), with P beliefs and concerns about using opioids for chronic noncancer pain changed after participating in a 4-hour interactive workshop.

    Music therapy is frequently used as a palliative therapy. In consonance with the goals of palliative care, the primary aim of music therapy is to improve people's quality of life by addressing their psychological needs and facilitating communication. To date, primarily because of a paucity of robust research, the evidence for music therapy's effectiveness on patient reported outcomes is positive but weak. This pilot and feasibility study will test procedures, outcomes and validated tools; estimate recruitment and attrition rates; and calculate the sample size required for a phase III randomised trial to evaluate the effectiveness of music therapy in improving the quality of life of palliative care patients. A pilot randomised controlled trial supplemented with qualitative methods. The quantitative data collection will involve recruitment of >52 patients from an inpatient Marie Curie hospice setting over a 12-month period. Eligibility criteria include all patients with an Eastern Cooperative Oncology Group (ECOG) performance status of 03- indicating they are medically fit to engage with music therapy and an Abbreviated Mental Test (AMT) score of ≥7 indicating they are capable of providing meaningful informed consent and accurate responses to outcome measures. Baseline data collection will include the McGill Quality of Life Questionnaire (MQOL); medical and socio-demographic data will be undertaken before randomisation to an intervention or control group. Participants in the intervention arm will be offered two 30-45 min sessions of music therapy per week for three consecutive weeks, in addition to care as usual. Participants in the control arm will receive care as usual. Follow-up measures will be administered in 1, 3 and 5 weeks. Qualitative data collection will involve focus group and individual interviews with HCPs and carers. This study will ensure a firm methodological grounding for the development of a robust phase III randomised trial of music therapy for

    In this paper, fluid dynamics of Fluid Catalytic Cracking (FCC) process is investigated by means of a Cold Flow Pilot Unit (CFPU) constructed in Plexiglas to visualize operational conditions. Axial and radial catalyst profiles were measured by gamma ray transmission in the riser of the CFPU. Standard uncertainty was evaluated in volumetric solid fraction measurements for several concentrations at a given point of axial profile. Monitoring of the pressure drop in riser shows a good agreement with measured standard uncertainty data. A further evaluation of the combined uncertainty was applied to volumetric solid fraction equation using gamma transmission data. Limit condition of catalyst concentration in riser was defined and simulation with random numbers provided by MATLAB software has tested uncertainty evaluation. The Guide to the expression of Uncertainty in Measurement (GUM) is based on the law of propagation of uncertainty and on the characterization of the quantities measured by means of either a Gaussian distribution or a t-distribution, which allows measurement uncertainty to be delimited by means of a confidence interval.

    To evaluate a social support intervention that was culturally tailored for Chinese Americans who face many challenges because of cultural and linguistic barriers. Intervention with a one-group pre- or post-test design, mixed methods, and a community-based participatory research (CBPR) approach. Southern California. 14 Chinese American breast cancer survivors post-treatment and eight breast cancer peer mentors. The intervention was a 10-week program to provide emotional and informational support through peer mentoring and education. Health outcomes were assessed before and after the intervention. Eight weekly process evaluations and two focus group interviews also were conducted. Depressive and anxiety symptoms. The program was associated with a decrease in depressive symptoms. Participants valued the program highly. Inductive analysis suggested possible mechanisms for effectiveness, such as reducing stigma, empowerment, and increased sense of belonging. The peer-mentoring and education program has the potential to serve as a model intervention for ethnic minorities. Mixed methods and CBPR are valuable in evaluating pilot interventions with minorities. Focusing on relationships may be fruitful for designing novel interventions for cancer survivors from collectivistic cultures. Peer-mentoring and education programs can be integrated into communities and clinics to improve care for underserved minority cancer survivors and to reduce health disparities.

    In this paper, fluid dynamics of Fluid Catalytic Cracking (FCC) process is investigated by means of a Cold Flow Pilot Unit (CFPU) constructed in Plexiglas to visualize operational conditions. Axial and radial catalyst profiles were measured by gamma ray transmission in the riser of the CFPU. Standard uncertainty was evaluated in volumetric solid fraction measurements for several concentrations at a given point of axial profile. Monitoring of the pressure drop in riser shows a good agreement with measured standard uncertainty data. A further evaluation of the combined uncertainty was applied to volumetric solid fraction equation using gamma transmission data. Limit condition of catalyst concentration in riser was defined and simulation with random numbers provided by MATLAB software has tested uncertainty evaluation. The Guide to the expression of Uncertainty in Measurement (GUM) is based on the law of propagation of uncertainty and on the characterization of the quantities measured by means of either a Gaussian distribution or a t-distribution, which allows measurement uncertainty to be delimited by means of a confidence interval. A variety of supplements to GUM are being developed, which will progressively enter into effect. The first of these supplements [3] describes an alternative procedure for the calculation of uncertainties: the Monte Carlo Method (MCM).MCM is an alternative to GUM, since it performs a characterization of the quantities measured based on the random sampling of the probability distribution functions. This paper also explains the basic implementation of the MCM method in MATLAB. (author)

    The purpose of mammography has been to provide the contrast between the lesion and adjacent healthy tissue of the breast. The quality control which should be performed in mammography services is essential to obtain the necessary contrast in mammography and thus achieve a prompt detection of breast lesions. The quality control program has helped to obtain exact diagnosis in mammography and has contributed to reduce mortality from breast cancer in Costa Rica. The Caja Costarricense de Seguro Social (CCSS) has sought to improve the quality of mammograms performed in the different health centers by implementing quality control programs in the services. The evaluation of the physical parameters has had as aim to perform an assessment of the equipment used in mammography facilities. The image quality, dosimetry, optical density, performance, accuracy and repeatability of voltage applied to the tube, filtration and Half-value layer in system of screen film mammography have been evaluated. The usefulness of quality control programs and needs of the services to implement a pilot plan for breast screening, can be seen when comparing the obtained results. The protocol of Mammography Quality Control, TECDOC 1517 from the International Atomic Energy Agency (IAEA), is implemented with this project and the associated software in four of the six hospitals evaluated in this study.

    To conduct a process and impact evaluation of a multifaceted education-based pilot program targeting correct use of age-appropriate restraints in a regional setting with a high proportion of Aboriginal and Torres Strait Islander families. The program was delivered in 2010 in 3 early learning centers where 31 percent of the children were of Aboriginal and Torres Strait Islander descent. Each component of the program was assessed for message consistency and uptake. To measure program effectiveness, participating children were matched 1:1 by age, language spoken at home, and annual household income with 71 children from the control arm of a contemporaneous trial. The outcome measure in the control and program centers (a 4-category ordinal scale of restraint use) was compared using ordinal logistic regression accounting for age of the parent. Process evaluation found that though program components were delivered with a consistency of message, uptake was affected by turnover of all staff at one center and by parents experiencing difficulty in paying for subsidized restraints at each of the centers. Impact evaluation found that children from the centers receiving the program had nearly twice the odds of being in a better restraint category than children matched from the control group (adjusted odds ratio [ORadj] = 2.06, 95% confidence interval [CI], 1.09-3.90). This was a pragmatic study reflecting the real-life issues of implementing a program in preschools where 57 percent of families had a low income and turnover of staff was high. Despite these issues, impact evaluation showed that the integrated educational program showed promise in increasing correct use of age-appropriate restraints. The findings from this pilot study support the use of an integrated educational program that includes access to subsidized restraints to promote best practice child restraint use among communities that include a high proportion of Aboriginal and Torres Strait Islander families in New

    A mobile HIV counseling and testing (HCT) program around Johannesburg piloted the integration of point-of-care (POC) CD4 testing, using the Pima analyzer, to improve linkages to HIV care. We report results from this pilot program for patients testing positive (n = 508) from May to October 2010. We analyzed 3 primary outcomes: assignment to testing group (offered POC CD4 or not), successful follow-up (by telephone), and completed the referral visit for HIV care within 8 weeks after HIV testing if successfully followed up. Proportions for each outcome were calculated, and relative risks were estimated using a modified Poisson approach. Three hundred eleven patients were offered the POC CD4 test, and 197 patients were not offered the test. No differences in patient characteristics were observed between the 2 groups. Approximately 62.7% of patients were successfully followed up 8 weeks after HIV testing, with no differences observed between testing groups. Among those followed up, 54.4% reported completing their referral visit. Patients offered the POC CD4 test were more likely to complete the referral visit for further HIV care (relative risk 1.25, 95% confidence interval: 1.00 to 1.57). In this mobile HCT setting, patients offered POC CD4 testing as part of the HCT services were more likely to visit a referral clinic after testing, suggesting that rapid CD4 testing technology may improve linkage to HIV care. Future research can evaluate options for adjusting HCT services if POC CD4 testing was included permanently and the cost-effectiveness of the POC CD4 testing compared with other approaches for improving linkage of care.

    The technical feasibility mechanisms and performance of degradation of several pesticides (imidacloprid, methomyl and diuron) dissolved in water have been studies at pilot scale in two well-defined photocatalytic systems of special interest because natural UV light can be used: heterogeneous photocatalysis with titanium dioxide and homogeneous photocatalysis by photo-Fenton.Equivalent pilot-scale (made up of Compound Parabolic Collectors (CPCs) specially designed for solar photocatalytic applications) and field conditions used for both systems and the three pesticides allowed adequate comparison of the degree of mineralization and toxicity achieved as well as the transformation products generated en route to mineralization. Total disappearance of the parent compounds and 90% mineralisation have been attained with all pesticides tested, methomyl being the most difficult to be degraded with both treatments. First order rate constants, initial rate,time necessary for mineralizing 90% of the initial TOC and hydrogen peroxide consumption were calculated in all cases, enabling comparison both of treatments and of the selected pesticide reactivity. Complete mineralisation of TOC is not achieved even after quite a long time (more than 300 minutes). Three different bioassays (Vibrio fischeri, Daphnia magna and a Microalga) have been used for testing the progress of toxicity during treatments. All remained toxic down to very low pesticide disappearance of the pesticide. Only if treatment is maintained throughout enough mineralisation (i. e. TOC disappearance), the toxicity is reduced to below the threshold (EC 50%). Transformation products evaluated by GC-MS/AED (after two SPE procedures), LC-IT-MS and LC-IC were the same in both phototreatments. The main differences between the two processes are in the amount of transformation products (TPs) generated, not in the TPs detected which were always the same. (Author)

    Despite advances in treatment of people living with HIV, morbidity and mortality remains unacceptably high in sub-Saharan Africa, largely due to parallel epidemics of poverty and food insecurity. We conducted a pilot cluster randomized controlled trial (RCT) of a multisectoral agricultural and microfinance intervention (entitled Shamba Maisha) designed to improve food security, household wealth, HIV clinical outcomes and women's empowerment. The intervention was carried out at two HIV clinics in Kenya, one randomized to the intervention arm and one to the control arm. HIV-infected patients >18 years, on antiretroviral therapy, with moderate/severe food insecurity and/or body mass index (BMI) loan (~$150) to purchase the farming commodities, 2) a micro-irrigation pump, seeds, and fertilizer, and 3) trainings in sustainable agricultural practices and financial literacy. Enrollment of 140 participants took four months, and the screening-to-enrollment ratio was similar between arms. We followed participants for 12 months and conducted structured questionnaires. We also conducted a process evaluation with participants and stakeholders 3-5 months after study start and at study end. Baseline results revealed that participants at the two sites were similar in age, gender and marital status. A greater proportion of participants at the intervention site had a low BMI in comparison to participants at the control site (18% vs. 7%, p = 0.054). While median CD4 count was similar between arms, a greater proportion of participants enrolled at the intervention arm had a detectable HIV viral load compared with control participants (49% vs. 28%, respectively, p loans, agricultural challenges due to weather patterns, and a challenging partnership with the microfinance institution. We expect the results from this pilot study to provide useful data on the impacts of livelihood interventions and will help in the design of a definitive cluster RCT.

    The aim of this study was to evaluate the effects of an mHealth intervention (intervention using mobile technology) consisting of tailored advice regarding exposure to daylight, sleep, physical activity, and nutrition, and aiming to improve health-related behavior, thereby reducing sleep problems and fatigue and improving health perception of airline pilots. A randomized controlled trial was conducted among 502 airline pilots. The intervention group was given access to both the MORE Energy mobile application (app) with tailored advice and a website with background information. The control group was directed to a website with standard information about fatigue. Health-related behavior, fatigue, sleep, and health perception outcomes were measured through online questionnaires at baseline and at three and six months after baseline. The effectiveness of the intervention was determined using linear and Poisson mixed model analyses. After six months, compared to the control group, the intervention group showed a significant improvement on fatigue (β= -3.76, P<0.001), sleep quality (β= -0.59, P=0.007), strenuous physical activity (β=0.17, P=0.028), and snacking behavior (β= -0.81, P<0.001). No significant effects were found for other outcome measures. The MORE Energy mHealth intervention reduced self-reported fatigue compared to a minimal intervention. Some aspects of health-related behavior (physical activity and snacking behavior) and sleep (sleep quality) improved as well, but most did not. The results show offering tailored advice through an mHealth intervention is an effective means to support employees who have to cope with irregular flight schedules and circadian disruption. This kind of intervention might therefore also be beneficial for other working populations with irregular working hours.

    In May 1980 it was decided to organize an intercomparison of personal dosimeters for photon radiations. The Commission of the European Communities initiated the intercomparison by starting a pilot study in which three laboratories NPL (United Kingdom), PTB (Germany) and RIV (The Netherlands) were asked to irradiate a series of personal dosemeters from institutes, GSF (Muenchen), CEA (Fontenay-aux-Roses), CNEN (Bologna) and CEGB (Berkeley). The latter institutes are secondary standard laboratories and have a radiation protection service as well. A new aspect of this pilot study is the fact that the irradiations also take place in front of a phantom. Irradiations took place in July and August 1980. The results of 4 institutes show that the personal dosemeters are quite capable of measuring the backscattered photon components

    The late life disability instrument (LLDI) was developed to assess limitations in instrumental and management roles using a small and restricted sample. In this paper we examine the measurement properties of the LLDI using data from the Lifestyle Interventions and Independence for Elders Pilot (LIFE-P) study. LIFE-P participants, aged 70-89 years, were at elevated risk of disability. The 424 participants were enrolled at the Cooper Institute, Stanford University, University of Pittsburgh, and Wake Forest University. Physical activity and successful aging health education interventions were compared after 12-months of follow-up. Using factor analysis, we determined whether the LLDI's factor structure was comparable with that reported previously. We further examined how each item related to measured disability using item response theory (IRT). The factor structure for the limitation domain within the LLDI in the LIFE-P study did not corroborate previous findings. However, the factor structure using the abbreviated version was supported. Social and personal role factors were identified. IRT analysis revealed that each item in the social role factor provided a similar level of information, whereas the items in the personal role factor tended to provide different levels of information. Within the context of community-based clinical intervention research in aged populations, an abbreviated version of the LLDI performed better than the full 16-item version. In addition, the personal subscale would benefit from additional research using IRT. The protocol of LIFE-P is consistent with the principles of the Declaration of Helsinki and is registered at http://www.ClinicalTrials.gov (registration # NCT00116194).

    Goniometers are commonly used by physical therapists to measure range-of-motion (ROM) in the musculoskeletal system. These measurements are used to assist in diagnosis and to help monitor treatment efficacy. With newly emerging technologies, smartphone-based applications are being explored for measuring joint angles and movement. This pilot study investigates the intra- and inter-rater reliability as well as concurrent validity of a newly-developed smartphone magnetometer-based goniometer (MG) application for measuring passive shoulder abduction in both sitting and supine positions, and compare against the traditional universal goniometer (UG). This is a comparative study with repeated measurement design. Three physical therapists utilized both the smartphone MG and a traditional UG to measure various angles of passive shoulder abduction in a healthy subject, whose shoulder was positioned in eight different positions with pre-determined degree of abduction while seated or supine. Each therapist was blinded to the measured angles. Concordance correlation coefficients (CCCs), Bland-Altman plotting methods, and Analysis of Variance (ANOVA) were used for statistical analyses. Both traditional UG and smartphone MG were reliable in repeated measures of standardized joint angle positions (average CCC > 0.997) with similar variability in both measurement tools (standard deviation (SD) ± 4°). Agreement between the UG and MG measurements was greater than 0.99 in all positions. Our results show that the smartphone MG has equivalent reliability compared to the traditional UG when measuring passive shoulder abduction ROM. With concordant measures and comparable reliability to the UG, the newly developed MG application shows potential as a useful tool to assess joint angles. Published by Elsevier Ltd.

    The educational literature generally suggests that supplemental instruction (SI) is effective in improving academic performance in traditionally difficult courses. A pilot program of peer teaching based on the SI model was implemented for an undergraduate course in human anatomy. Students in the course were stratified into three groups based on the number of peer teaching sessions they attended: nonattendees (0 sessions), infrequently attended (1-3 sessions), and frequently attended (≥ 4 sessions). After controlling for academic preparedness [i.e., admission grade point average (AGPA)] using an analysis of covariance, the final grades of frequent attendees were significantly higher than those of nonattendees (P = 0.025) and infrequent attendees (P = 0.015). A multiple regression analysis was performed to estimate the relative independent contribution of several variables in predicting the final grade. The results suggest that frequent attendance (β = 0.245, P = 0.007) and AGPA (β = 0.555, P < 0.001) were significant positive predictors, while being a first-year student (β = -0.217, P = 0.006) was a significant negative predictor. Collectively, these results suggest that attending a certain number of sessions may be required to gain a noticeable benefit from the program, and that first-year students (particularly those with a lower level of academic preparedness) would likely stand to benefit from maximally using the program. End-of-semester surveys and reports indicate that the program had several additional benefits, both to the students taking the course and to the students who served as program leaders.

    2012-01-01

    Background Implementing new initiatives and physical activity interventions in schools represents a myriad of challenges that if overcome can potentially facilitate a range of behavioural changes. The aim of this paper is to describe the process evaluation of specific design constructs used in the GLAMA (Girls! Lead! Achieve! Mentor! Activate!) peer leadership and physical activity pilot project. Conducted in a state secondary school in Australia, the intervention was designed to provide students with opportunities to develop leadership skills, school and social connectedness in addition to a range of physical activity experiences. Methods This process evaluation used the RE-AIM (Reach, Efficacy, Adoption, Implementation and Maintenance) health promotion evaluation framework to assess three design constructs of the intervention: the effectiveness of leadership training and leader preparedness, activity suitability and participation, and the barriers to implementation of the intervention and potential solutions to overcome these barriers. As it was not the specific aim of this pilot, no behavioural change data were collected from students. Data were collected using a mixed methods approach including student questionnaires, teachers and researchers reporting on their own observations and feedback from students. Results There were three main considerations evident across more than one RE-AIM dimension that need to be addressed to assist with future GLAMA dissemination. Firstly, the development of teacher, school and student participation. This needs to be through a variety of professional development opportunities for teachers, integration of the program within timetabled classes within the school and promoting the program to students as an opportunity to develop a range of skills to apply to future learning and workplace environments. Secondly, the successful translation of leadership training to practice is necessary to ensure that leaders are effectively able to

    The feasibility of reclaiming effluent from industrial park wastewater treatment plants through a membrane process was evaluated in three phases. In phase 1 we selected nine wastewater treatment plants (WWTPs), each with a design capacity exceeding 10,000 m3 d(-1), and analyzed the corresponding effluent composition. 'Potential recycling percentage', R, ranged from 50% to 80% for the industrial park WWTPs, indicating a high feasibility for the reuse of effluent. In phase 2, a 50 m3 d(-1) pilot plant was installed in one of the selected WWTPs and underwent testing for one year. The quality of the reclaimed water was suitable for general-purpose industrial use. In the two ultrafiltration (UF) modules tested, the hydrophilic polyethersulfone hollow-fibre module was more tolerant to variable properties, and had higher recycling percentages than those of backwashable hydrophobic polyvinylidene difluoride spiral-wound module. Using the spiral-wound UF module helped reduce the cost for producing 1 m3 of reclaimed water (US$0.80) compared with a hollow-fibre module (US$0.88). In phase 3, we evaluated the negative effects of refluxing the reverse osmosis retentate, containing high total dissolved solids and non-biodegradable organics, with the biological treatment unit of the upstream WWTP. Biological compactibility tests showed that the refluxed retentate ratio should be reduced to maintain the conductivity of mixed liquor in the aeration tank at less than 110% of the original value.

    Fat Talk Free Week (FTFW), a social marketing campaign designed to decrease self-disparaging talk about body and weight, has not yet been evaluated. We conducted a theory-informed pilot evaluation of FTFW with two college samples using a pre- and posttest design. Aligned with the central tenets of the Elaboration Likelihood Model (ELM), we investigated the importance of FTFW saliency as a predictor of fat talk behavior change. Our analytic sample consisted of 118 female participants (83% of original sample). Approximately 76% of the sample was non-Hispanic White, 14% Asian, and 8% Hispanic. At baseline, more than 50% of respondents reported engaging in frequent self fat talk; at posttest, this number dropped to 34% of respondents. Multivariable regression models supported campaign saliency as the single strongest predictor of a decrease in self fat talk. Our results support the social diffusion of campaign messages among shared communities, as we found significant decreases in fat talk among campaign attenders and nonattenders. FTFW may be a promising short-term health communication campaign to reduce fat talk, as campaign messages are salient among university women and may encourage interpersonal communication.

    Previous studies have shown the possibility that animal-assisted therapy (AAT) is useful for promoting the recovery of a patient's psychological, social, and physiological aspect. As a pilot study, we measured the effect that AAT had on cerebral activity using near-infrared spectroscopy (NIRS), and examined whether or not NIRS be used to evaluate the effect of AAT biologically and objectively. Two patients with mood [affective] disorders and a healthy subject participated in this study. We performed two AAT and the verbal fluency task (VFT). The NIRS signal during AAT showed great [oxy-Hb] increases in most of the prefrontal cortex (PFC) in the two patients. When the NIRS pattern during AAT was compared with that during VFT, greater or lesser differences were observed between them in all subjects. The present study suggested that AAT possibly causes biological and physiological changes in the PFC, and that AAT is useful for inducing the activity of the PFC in patients with depression who have generally been said to exhibit low cerebral activity in the PFC. In addition, the possibility was also suggested that the effect of AAT can be evaluated using NIRS physiologically and objectively.

    Full Text Available This pilot study simultaneously evaluated the effects of various factors, including genetic variations of CYP2B6, CYP2C19, and ABCB1, demographic characteristics, disease states, methadone-drug interactions (MDIs, and poly-substance use, on the treatment responses among non-HIV patients in the methadone maintenance treatment program (MMTP in Taiwan. A total of 178 patients were recruited from two major hospitals that provided MMTP services in southern Taiwan, and information regarding concomitant medications and diseases was acquired from the National Health Insurance (NHI program. The results demonstrated that the methadone maintenance dose, CYP2B6 785G allele, and ABCB1 2677T allele have positive effects on the methadone plasma concentration. In contrast, patients with HCV coinfection, alcohol problems, and psychiatric diseases may have a negative response to treatment. Thus, a comprehensive evaluation of treatment responses in the MMTP should include not only genetic polymorphisms in methadone metabolism and transporter proteins, but also concomitant diseases, MDIs, and poly-substance use. The results also suggest that personalized medicine may be indispensable for a better outcome of the MMTP.

    Despite the interest in the impact of overweight and obesity on public health, little is known about the social and economic impact of being born large for gestational age or macrosomic. Both conditions are related to maternal obesity and/or gestational diabetes mellitus (GDM) and associated with increased morbidity for mother and child in the perinatal period. Poorly controlled diabetes during pregnancy, pre- pregnancy maternal obesity and/or excessive maternal weight gain during pregnancy are associated with intermittent periods of fetal exposure to hyperglycemia and subsequent hyperinsulinemia, leading to increased birth weight (e.g., macrosomia), body adiposity, and glycogen storage in the liver. Macrosomia is associated with an increased risk of developing obesity and type 2 diabetes mellitus later in life. Provide insight in the short-term health-economic impact of maternal overweight, GDM, and related macrosomia. To this end, a health economic framework was designed. This pilot study also aims to encourage further health technology assessments, based on country- and population-specific data. The estimation of the direct health-economic burden of maternal overweight, GDM and related macrosomia indicates that associated healthcare expenditures are substantial. The calculation of a budget impact of GDM, based on a conservative approach of our model, using USA costing data, indicates an annual cost of more than $1,8 billion without taking into account long-term consequences. Although overweight and obesity are a recognized concern worldwide, less attention has been given to the health economic consequences of these conditions in women of child-bearing age and their offspring. The presented outcomes underline the need for preventive management strategies and public health interventions on life style, diet and physical activity. Also, the predisposition in people of Asian ethnicity to develop diabetes emphasizes the urgent need to collect more country

    A consortium of government, industry and academia is currently working to establish minimum operational performance standards for Detect and Avoid (DAA) and Control and Communications (C2) systems in order to enable broader integration of Unmanned Aircraft Systems (UAS) into the National Airspace System (NAS). One subset of these performance standards will need to address the DAA display requirements that support an acceptable level of pilot performance. From a pilot's perspective, the DAA task is the maintenance of self separation and collision avoidance from other aircraft, utilizing the available information and controls within the Ground Control Station (GCS), including the DAA display. The pilot-in-the-loop DAA task requires the pilot to carry out three major functions: 1) detect a potential threat, 2) determine an appropriate resolution maneuver, and 3) execute that resolution maneuver via the GCS control and navigation interface(s). The purpose of the present study was to examine two main questions with respect to DAA display considerations that could impact pilots' ability to maintain well clear from other aircraft. First, what is the effect of a minimum (or basic) information display compared to an advanced information display on pilot performance? Second, what is the effect of display location on UAS pilot performance? Two levels of information level (basic, advanced) were compared across two levels of display location (standalone, integrated), for a total of four displays. The authors propose an eight-stage pilot-DAA interaction timeline from which several pilot response time metrics can be extracted. These metrics were compared across the four display conditions. The results indicate that the advanced displays had faster overall response times compared to the basic displays, however, there were no significant differences between the standalone and integrated displays. Implications of the findings on understanding pilot performance on the DAA task, the

    The Spinal Cord Impairment Pressure Ulcer Monitoring Tool (SCI-PUMT) was designed to assess pressure ulcer (PrU) healing in the spinal cord impaired (SCI) population. The tool contains 7 variables: wound surface area, depth, edges, tunneling, undermining, exudate type, and necrotic tissue amount. A 2-phased, quantitative pilot study based on the Theory of Reasoned Action and Theory of Planned Behavior was conducted at a large SCI/Disorders Center in the Department of Veterans Affairs (VA). In the first phase of the study, a convenience sample of 5 physicians, 3 advanced practice registered nurses, and 3 certified wound care nurses (CWCN) was surveyed using a 2-part questionnaire to assess use of the SCI-PUMT instrument, its anticipated improvement in PrU assessment, and intent to use the SCI-PUMT in clinical practice. Attitudes, subjective norms, perceived behavioral controls, and barriers related to the intent to use the SCI-PUMT were evaluated using a 5-point Likert scale (range: 1= extremely likely, 5 = extremely unlikely). In the second phase of the study, the electronic health records (EHR) of 24 veterans (with 30 PrUs) who had at least 2 completed SCI-PUMT scores during a 4-week period were used to evaluate whether an association existed between magnitudes of change of total SCI-PUMT scores and ordered changes in PrU treatment. The overall mean score for intent to use SCI-PUMT was 1.80 (SD 0.75). The least favorable scores were for convenience and motivation to use the SCI-PUMT. Analysis of EHR data showed no significant difference in magnitudes of change in the SCI-PUMT score and changes in PrU treatment recommendations made by the CWCNs. The significance was not affected regardless of an increase or no change in the score (χ2 with 1 degree of freedom = 1.158, P = 0.282) or for a decrease in the score (χ2 with 1 degree of freedom = 0.5, P = 0.478). In this pilot study, the expressed intent to use the SCI-PUMT in making clinical decisions was generally

    Purpose: To develop a magnetic resonance imaging (MRI) metric that is useful for therapy monitoring in patients with relapsed glioblastoma (GBM) during treatment with the antiangiogenic monoclonal antibody bevacizumab (Bev). We evaluated the feasibility of tumour volume measurement with our software tool in clinical routine and tried to establish reproducible and quantitative parameters for surveillance of patients on treatment with antiangiogenic drugs. Materials and methods: In this retrospective institutional pilot study, 18 patients (11 men, 7 women; mean age 53.5) with recurrent GBM received bevacizumab and irinotecan every two weeks as second line therapy. Follow up scans were assessed every two to four months. Data were collected on a 1.5 T MR System (Siemens, Symphony) with the standard head coil using our standardized tumour protocol. Volumetric measurement was performed with a commercial available software stroketool in FLAIR and T1-c imaging with following procedure: Pre-processing involved cutting noise and electing a Gaussian of 3 × 3 to smooth images, selecting a ROI (region of interest) in healthy brain area of the contra lateral side with quantifying the intensity value, adding 20% to this value to define the threshold level. Only values above this threshold are left corresponding to the tumour lesion. For the volumetric measurement the detected tumour area was circuited in all slices and finally summing up all values and multiplied by slice thickness to get the whole volume. Results: With McDonalds criteria progression was indicated in 14 out of 18 patients. In contrast, volumetric measurement showed an increase of contrast enhancement of >25%, defined as threshold for progression, in 11 patients (78%) and in 12 patients (85%) in FLAIR volume, respectively. 6 patients revealed that volumes in MRI increased earlier than the last scan, which was primarily defined as the date of progression with McDonald criteria, changing PFS after re-evaluation of

  20. Evaluation of the effectiveness and feasibility of the Waste Isolation Pilot Plant engineered alternatives: Final report of the Engineered Alternatives Task Force

    International Nuclear Information System (INIS)

    1991-07-01

    The Engineered Alternatives Task Force (EATF) was established by the United States Department of Energy (DOE) WIPP Project Office (WPO) in September 1989 (Hunt, A., 1990), to evaluate the relative effectiveness and feasibility of implementation of selected design enhancements (referred to as ''engineered alternatives'') for the Waste Isolation Pilot Plant (WIPP). These enhancements consist of modifications of existing waste forms and/or the WIPP facility, and other design variations such as passive marker systems. The purpose of this report is to summarize the methodologies and results of evaluation of the effectiveness of selected engineered alternatives relative to the existing repository design, and to discuss the feasibility of implementing these alternatives with respect to availability of technology, cost, schedule, and regulatory concerns. The EATF has concluded that a number of engineered alternatives could be implemented to improve repository performance if WIPP performance assessment determines that either gas generation or human intrusion presents a problem in demonstrating compliance. Within waste treatment, Level 3 treatments are the most effective in addressing multiple performance parameters, but tend to be the most expensive, the most difficult and time-consuming to implement, and have the greatest regulatory requirements. Level 2 treatments are less expensive, faster, require less extensive permitting, and utilize off- the-shelf technology, but are less effective in addressing multiple performance parameters. Depending upon the performance parameter, Level 1 alternatives such as alternative backfills, alternative waste containers, or modified repository design should be thoroughly evaluated and eliminated before any decision is made to treat the waste. The present uncertainty in the degree to which the baseline WIPP design complies with 40 CFR Part 191 and 40 CFR Part 268 precludes specific recommendations at this time. 130 refs., 21 figs., 37 tabs

    2015-12-01

    Recent developments in high energy physics (HEP) including multi-core jobs and multi-core pilots require data centres to gain a deep understanding of the system to monitor, design, and upgrade computing clusters. Networking is a critical component. Especially the increased usage of data federations, for example in diskless computing centres or as a fallback solution, relies on WAN connectivity and availability. The specific demands of different experiments and communities, but also the need for identification of misbehaving batch jobs, requires an active monitoring. Existing monitoring tools are not capable of measuring fine-grained information at batch job level. This complicates network-aware scheduling and optimisations. In addition, pilots add another layer of abstraction. They behave like batch systems themselves by managing and executing payloads of jobs internally. The number of real jobs being executed is unknown, as the original batch system has no access to internal information about the scheduling process inside the pilots. Therefore, the comparability of jobs and pilots for predicting run-time behaviour or network performance cannot be ensured. Hence, identifying the actual payload is important. At the GridKa Tier 1 centre a specific tool is in use that allows the monitoring of network traffic information at batch job level. This contribution presents the current monitoring approach and discusses recent efforts and importance to identify pilots and their substructures inside the batch system. It will also show how to determine monitoring data of specific jobs from identified pilots. Finally, the approach is evaluated.

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

    Satisfaction with continuing education can be defined as positive attitudes towards educational programs, which has potential to strengthen learning outcomes. A multi-dimensional construct may enhance continuing education program evaluation processes. The objective is to describe the development and psychometric testing of the 'affective - behavioral - cognitive - satisfaction questionnaire' (ABC-SAT) for assessing participants' satisfaction with a continuing education program for nurses in infection control. The multi-staged development of a satisfaction questionnaire comprised of three subscales. The pilot tool was administered to a nationwide sample of 126 infection control nurses to assess satisfaction after participating in a continuing education program. Satisfaction scores were calculated and psychometric testing was performed to determine reliability, using Cronbach's alpha, face validity, objectivity, and economy. A principle component analysis using varimax rotation and Kaiser normalization was performed. The analysis led to a three-factor solution of the questionnaire with 11 items, explaining 61.4% of the variance. Internal consistency of three scales using Cronbach's alpha was 0.83, 0.60, and 0.66, respectively. Selectivity coefficients varied between 0.39 and 0.70. Participants needed approximately three minutes to complete the questionnaire. Initial findings refer to a satisfying scale structure and internal consistency of the 3-dimensional ABC-SAT questionnaire. Further research is required to confirm the questionnaires' psychometric properties. Copyright © 2018 Elsevier Ltd. All rights reserved.

    Acute postoperative pain delays recovery and increases morbidity and mortality. Traditional administration of postoperative analgesics by nurses is often inefficient. The present study evaluated the safety, efficacy, and usability of a novel, patient-controlled analgesic dispenser, the PCoA Acute. A controlled pilot study was conducted at three medical centers. Patients scheduled for elective surgery were enrolled into two groups, both taking oral analgesics: a control group ( n = 43), opioids dispensed by nurses, and a test group ( n = 27), opioids dispensed via the PCoA Acute. Pill intake data were recorded. Pain ratings at rest and during movement were surveyed. No severe adverse events were recorded. Average pill intake time was reduced from 8 : 58 minutes in the control group to 1 : 17 minutes in the test group ( P value PCoA Acute users were satisfied with its use. The study confirmed that PCoA Acute is safe and effective. It is well accepted by patients and medical staff. Its use can optimize pain medication administration.

Objective: To evaluate levels of thyroid-stimulation hormone (TSH in the program congenital hypothyroidism (CH newborn screening in a sample of preterm infants in the city of Bogotá, Colombia. Methods: The Secretaría de Salud Distrital screening protocol for CH (blood sample is collected from the umbilical cord in all the newborns remeasured the serum TSH and heel TSH when preterm infants completed 37 weeks of gestation. Results: A total of 59 preterm neonates were rescreened, of which 2 neonates had elevated levels of TSH and 1 neonate had transient hypothyroxinemia. The Kolmogorov-Smirnov 2-sample/bilateral statistical test was used to compare the neonatal TSH levels of preterm and full-term newborns, which do not follow the same distribution. Conclusion: In our pilot study, 2 of the rescreened infants presented high levels of TSH and 1 had transient hyperthyrotropinemia, suggesting the need for rescreening of preterm infants. Additionally, a larger study should be performed to determine the screening cutoff values for preterm newborns.

    This project examines the implementation of an exterior insulation and over-clad strategy for brick masonry buildings in Chicago—a free-standing two story two-family dwelling and a larger free-standing multifamily building. The test homes selected for this research represent predominant housing types for the Chicago area, in which high heating energy use typical in these buildings threaten housing affordability, and uninsulated mass masonry wall assemblies are uncomfortable for residents. In this project, the Community and Economic Development Association of Cook County, Inc. (CEDA) has secured a Sustainable Energy Resources for Consumers (SERC) innovation grant sponsored by DOE to pursue a pilot implementation of innovative approaches to retrofit in masonry wall enclosures. The retrofit measures are evaluated in terms of feasibility, cost and performance. Through observations of the strategies implemented, the research described in this report identifies measures critical to performance as well as conditions for wider adoption. The research also identifies common factors that must be considered in determining whether the exterior insulation and over-clad strategy is appropriate for the building.

    This project examines the implementation of an exterior insulation and over-clad strategy for brick masonry buildings in Chicago. The strategy was implemented at a free-standing two story two-family dwelling and a larger free-standing multifamily building. The test homes selected for this research represent predominant housing types for the Chicago area. High heating energy use typical in these buildings threaten housing affordability. Uninsulated mass masonry wall assemblies also have a strongly detrimental impact on comfort. Significant changes to the performance of masonry wall assemblies is generally beyond the reach of typical weatherization (Wx) program resources. The Community and Economic Development Association of Cook County, Inc. (CEDA) has secured a Sustainable Energy Resources for Consumers (SERC) innovation grant sponsored by the United States Department of Energy (DOE). This grant provides CEDA the opportunity to pursue a pilot implementation of innovative approaches to retrofit in masonry wall enclosures. The exterior insulation and over-clad strategy implemented through this project was designed to allow implementation by contractors active in CEDA weatherization programs and using materials and methods familiar to these contractors. The retrofit measures are evaluated in terms of feasibility, cost and performance. Through observations of the strategies implemented, the research described in this report identifies measures critical to performance as well as conditions for wider adoption. The research also identifies common factors that must be considered in determining whether the exterior insulation and over-clad strategy is appropriate for the building.

    Full Text Available Background. Acute postoperative pain delays recovery and increases morbidity and mortality. Traditional administration of postoperative analgesics by nurses is often inefficient. The present study evaluated the safety, efficacy, and usability of a novel, patient-controlled analgesic dispenser, the PCoA Acute. Methods. A controlled pilot study was conducted at three medical centers. Patients scheduled for elective surgery were enrolled into two groups, both taking oral analgesics: a control group (n=43, opioids dispensed by nurses, and a test group (n=27, opioids dispensed via the PCoA Acute. Pill intake data were recorded. Pain ratings at rest and during movement were surveyed. Results. No severe adverse events were recorded. Average pill intake time was reduced from 8 : 58 minutes in the control group to 1 : 17 minutes in the test group (P value < 0.05. The test group took 67% more pills than the control group, indicating enhanced compliance. Pain scores were significantly lower for patients in the test group (P value < 0.05. Over 90% of PCoA Acute users were satisfied with its use. Conclusions. The study confirmed that PCoA Acute is safe and effective. It is well accepted by patients and medical staff. Its use can optimize pain medication administration.

    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.

  10. Evaluation of the effectiveness and feasibility of the Waste Isolation Pilot Plant engineered alternatives: Final report of the Engineered Alternatives Task Force

    The Waste Isolation Pilot Plant (WIPP) near Carlsbad, New Mexico, is an underground repository designed for the geologic disposal of radioactive wastes resulting from the defense activities and programs of the United States Department of Energy (DOE). The performance of nuclear waste repositories is governed by US Environmental Protection Agency (EPA). The study conducted to demonstrate compliance with this regulation is called performance assessment. The EPA standard requires that DOE provide a reasonable assurance, based on performance assessment, that cumulative releases of radioactivity to the accessible environment will not exceed the standard's criteria. Preliminary performance assessment performed by SNL has indicated that the current design of the WIPP repository, together with the waste forms at the DOE storage and generating sites, may not demonstrate compliance with the EPA Standard. In view of this concern, and prompted by recommendations from external review groups, the DOE established the Engineered Alternatives Task Force (EATF) in September, 1989. The objective of the EATF is to identify potential engineering modifications (referred to as engineered alternatives) to the existing WIPP design and/or to the transuranic (TRU) waste forms, an to evaluate their effectiveness and feasibility in facilitating compliance with the EPA Standard. These alternatives would be designed to completely eliminate or reduce any problems which might cause non-compliance with the EPA Standard. 139 refs., 39 figs., 124 tabs
