    The Feed Materials Production Center was constructed to produce high purity uranium metal for use at various Department of Energy facilities. The waste products from these operations include general uncontaminated scrap and refuse, contaminated and uncontaminated metal scrap, waste oils, low-level radioactive waste, co-contaminated wastes, mixed waste, toxic waste, sludges from water treatment, and fly ash from the steam plant. This material is estimated to total more than 350,000 cubic meters. Other wastes stored in this area include laboratory chemicals and other combustible materials in the burn pit; fine waste stream sediments in the clear well; fly ash and waste oils in the two fly ash areas; lime-alum sludges and boiler plant blowdown in the lime sludge ponds; and nonradioactive sanitary waste, construction rubble, and asbestos in the sanitary landfill. A systematic survey of the surface soils throughout the Waste Storage Area, associated on-site drainages, and the fly ash piles was conducted using a Field Instrument for Detecting Low-Energy Radiation (FIDLER). Uranium is the most prevalent radioactive element in surface soil; U-238 is the principal radionuclide, ranging from 2.2 to 1790 pCi/g in the general Waste Storage Area. The maximum values for the next highest activity concentrations in the same area were 972 pCi/g for Th-230 and 298 pCi/g for U-234. Elevated activity concentrations of Th-230 were found along the K-65 slurry line, the maximum at 3010 pCi/g. U-238 had the highest value of 761 pCi/g in the drainage just south of pit no. 5. The upper fly ash area had the highest radionuclide activity concentrations in the surface soils with the maximum values for U-238 at 8600 pCi/g, U-235 at 2190 pCi/g, U-234 at 11,400 pCi/g, Tc-99 at 594 pCi/g, Ra-226 at 279 pCi/g, and Th-230 at 164 pCi/g.

  2. Investigation of background acoustical effect on online surveys: A case study of a farmers' market customer survey

    Tang, Xingdi

    Since the middle of 1990s, internet has become a new platform for surveys. Previous studies have discussed the visual design features of internet surveys. However, the application of acoustics as a design characteristic of online surveys has been rarely investigated. The present study aimed to fill that research gap. The purpose of the study was to assess the impact of background sound on respondents' engagement and satisfaction with online surveys. Two forms of background sound were evaluated; audio recorded in studios and audio edited with convolution reverb technique. The author recruited 80 undergraduate students for the experiment. These students were assigned to one of three groups. Each of the three groups was asked to evaluate their engagement and satisfaction with a specific online survey. The content of the online survey was the same. However, the three groups was exposed to the online survey with no background sound, with background sound recorded in studios; and with background sound edited with convolution reverb technique. The results showed no significant difference in engagement and satisfaction in the three groups of online surveys; without background sound, background sound recorded in studios, and background sound edited with convolution reverb technique. The author suggests that background sound does not contribute to online surveys in all the contexts. The industry practitioners should be careful to evaluate the survey context to decide whether the background sound should be added. Particularly, ear-piercing noise or acoustics which may link to respondents' unpleasant experience should be avoided. Moreover, although the results did not support the advantage of the revolution reverb technique in improving respondents' engagement and satisfaction, the author suggests that the potential of the revolution reverb technique in the applications of online surveys can't be totally denied, since it may be useful for some contexts which need further

  3. A meta-study investigating the sources of protest behaviour in stated preference surveys

    DEFF Research Database (Denmark)

    Mørkbak, Morten Raun; Olsen, Søren Bøye; Meyerhoff, Jürgen

      It is well known that some percentage of respondents participating in Stated Preference surveys will not give responses which reflect their true preferences. One reason is protest behaviour. If the distribution of protest responses is not independent of respondent demographics, the elicitation...... method, the question format, etc., then simply expelling protesters from surveys will lead to sample selection issues. Furthermore, WTP estimates will not be comparable across surveys. This paper seeks to explore potential causes of protest behaviour through a meta-study based on data from 10 different...... surveys. The objective of the study is to examine the effect of respondent specific variables as well as survey specific variables on protest behaviour. Our results suggest that some of the differences in WTP typically observed between different demographic groups, different elicitation formats...

  8. Study on Developments in Accident Investigation Methods: A Survey of the 'State-of-the-Art'

    2008-01-15

    The objective of this project was to survey the main accident investigation methods that have been developed since the early or mid-1990s. The motivation was the increasing frequency of accidents that defy explanations in simple terms, for instance cause-effect chains or 'human error'. Whereas the complexity of socio-technical systems is steadily growing across all industrial domains, including nuclear power production, accident investigation methods are only updated when their inability to account for novel types of accidents and incidents becomes inescapable. Accident investigation methods therefore typically lag behind the socio-technological developments by 20 years or more. The project first compiled a set of methods from the recognised scientific literature and in major major research and development programs, excluding methods limited to risk assessment, technological malfunctions, human reliability, and safety management methods. An initial set of 21 methods was further reduced to seven by retaining only prima facie accident investigation methods and avoiding overlapping or highly similar methods. The second step was to develop a set of criteria used to characterise the methods. The starting point was Perrow's description of normal accidents in socio-technical systems, which used the dimensions of coupling, going from loose to tight, and interactions, going from linear to complex. For practical reasons, the second dimension was changed to that of tractability or how easy it is to describe the system, where the sub-criteria are the level of detail, the availability of an articulated model, and the system dynamics. On this basis the seven selected methods were characterised in terms of the systems - or conditions - they could account for, leading to the following four groups: methods suitable for systems that are loosely coupled and tractable, methods suitable for systems that are tightly coupled and tractable, methods suitable for systems that

    Systemic lupus erythematosus (SLE) can manifest with arthralgia and myalgia, and, in severe cases, disorganization of the joints and tendon rupture. Further, Raynaud's phenomenon and other circulatory problems such as vasculitis have been reported, and may be associated with loss of sensation and ulcers. Associated with impaired peripheral neurovascular function there is the potential for changes in tissue viability leading to thinning of the skin or callus formation. In addition, resistance to infections may be reduced, such as fungal infection of the skin and nails, bacterial infection associated with wounds and viral infections such as verruca. There is a dearth of evidence for the effects of SLE in the foot, the prevalence of foot problems in SLE and the impact of these on the individual. In addition, it is not known if people with SLE and foot problems have access to specialist care through foot health services. Hence, there is a need to investigate the scale of foot problems associated with SLE. In order to achieve this, a questionnaire needs to be developed in order to carry out a national survey in England. The items required for the questionnaire were generated using a focus group, which comprised patient advisers with SLE, consultants who specialized in SLE, specialist rheumatology podiatrists and specialist rheumatology nurses. From this consensus approach to the item generation, the draft questionnaire was developed with agreement on themes, question format and overall structure. Additionally, the Manchester Pain and Disability Questionnaire was included in order to capture levels of pain and associated disability. An iterative process followed, with feedback from the focus group reducing the number of other items from 53, until the penultimate version of questionnaire was produced with 50 items. Following on from this, a process of cognitive debriefing was used with two people with SLE who were naïve to the questionnaire. Minor changes to two

    A survey of technologies was conducted to provide information for a Data Quality Objectives process being conducted to support revision of the Remedial Investigation/Feasibility Study Work Plan for the 200-SW-2 Operable Unit. The technology survey considered remediation and characterization technologies. This effort was conducted to address, in part, comments on the previous version of the Remedial Investigation/Feasibility Study Work Plan for the 200-SW-2 Operable Unit as documented in 200­SW­1 and 200­SW­2 Collaborative Workshops-Agreement, Completion Matrix, and Supporting Documentation. By providing a thorough survey of remediation and characterization options, this report is intended to enable the subsequent data quality objectives and work plan revision processes to consider the full range of potential alternatives for planning of the Remedial Investigation/Feasibility Study activities.

  11. The value of DCIP geophysical surveys for contaminated site investigations

    DEFF Research Database (Denmark)

    Balbarini, Nicola; Rønde, Vinni Kampman; Maurya, Pradip Kumar

    Geophysical methods are increasingly being used in contaminant hydrogeology to map lithology, hydraulic properties, and contaminant plumes with a high ionic strength. Advances in the Direct Current resistivity and Induced Polarization (DCIP) method allow the collection of high resolution three...... dimensional (3D) data sets. The DC resistivity can describe both soil properties and the water electrical conductivity, while the IP can describe the lithology and give information on hydrogeological properties. The aim of the study was to investigate a large contaminant plume discharging to a stream from...... water and below the streambed. Surface DCIP surveys supported the characterization of the spatial variability in geology, hydraulic conductivity and contaminant concentration. Though DCIP data interpretation required additional borehole data, the DCIP survey reduced the number of boreholes required...

    Detailed investigations of 15 sites associated with seafloor faults and/or slope failures have been conducted with MBARI's Autonomous Underwater Vehicles (AUVs) and Remotely Operated Vehicles (ROVs). The motivation for these surveys is to better constrain neotectonic deformation of the seafloor and thus to evaluate potential seafloor geohazards. The coupled use of AUVs and ROVs has enabled marine neotectonic investigations to be achieved at similar observational detail to that previously only possible on land. The AUV surveys provide 1-m resolution bathymetric grids with vertical resolutions of ~10 cm along with chirp sub-bottom profiles that allow subtle deformation on and near the seafloor to be detected. ROV surveys enable precisely located push core and vibracore samples. Sampling strategies include taking transects of closely spaced cores across faults (comparable to trenching on land), and taking transects of horizontal push cores along the faces of scarps where reflectors in chirp profiles crop out or occur in the shallow subsurface. The timing of fault movement can then be established via radiocarbon dating of appropriate material within the sediment samples. The marine environment offers some inherent advantages for neotectonic investigations over the terrestrial environment, as the seafloor geomorphology is relatively unaffected by the deleterious effects of human development (agriculture and urbanization), has no vegetative cover, and is likely to experience continuous deposition of 14C datable materials. Examples will be shown of how AUV and ROV technologies help to constrain the extent, style, and timing of deformation associated with: the San Gregorio fault, offshore central California; the Palos Verdes and San Diego trough faults off southern California; transform faults within the Gulf of California; and young slump scars off Monterey, California. The increased resolution provided by these tools frequently leads to interpretations that differ from

    In 1991, the U.S. Congress established the National Water-Quality Assessment (NAWQA) program within the U.S. Geological Survey (USGS) to develop nationally consistent long-term datasets and provide information about the quality of the Nation’s streams and groundwater. The USGS uses objective and reliable data, water-quality models, and systematic scientific studies to assess current water-quality conditions, to identify changes in water quality over time, and to determine how natural factors and human activities affect the quality of streams and groundwater. NAWQA is the only non-regulatory Federal program to perform these types of studies; participation is voluntary. In the third decade (Cycle 3) of the NAWQA program (2013–2023), the USGS will evaluate the quality and availability of groundwater for drinking supply, improve our understanding of where and why water quality is degraded, and assess how groundwater quality could respond to changes in climate and land use. These goals will be addressed through the implementation of a new monitoring component in Cycle 3: Principal Aquifer Surveys.

    Geoelectric methods are sensitive to material properties which can be used to investigate subsurficial processes at contaminated sites. Electrical resistivity tomography (ERT) measures the electrical resistivity distribution in the ground; the self-potential (SP) method is based on source current densities resulting from ground water flow; and induced polarization (IP) responds to geochemical interactions between mineral surfaces and pore fluids. Ground water flow patterns and contaminant migration may be better understood if the results of these survey methods are interpreted jointly rather than separately. The purpose of this project is to jointly interpret results of geophysical surveying and laboratory characterization of soil and ground water samples to assess ground water flow patterns and contaminant migration at a site within the Oak Ridge National Laboratory. Historical disposal of liquid waste containing nitric acid and uranium in unlined ponds has resulted in contamination of soil and ground water. ERT, SP, and IP surveying was performed downgradient of the source area and the geophysical behavior of sediment and ground water samples was investigated in the laboratory. Measured electrical conductivity and self-potential anomalies coincided with elevated nitrate and uranium concentrations indicating preferential flow from the source area. The self-potential response can be related to ground water flow either by calculating the excess of charge in the diffuse layer surrounding mineral surfaces or by the streaming potential coupling coefficient. Geochemical reactions between pore water and minerals and their surfaces were modeled using the contaminant transport software TOUGHREACT. Surface complexation modeling using the Gouy-Chapman diffuse double layer was used to simulate charge density-surface potential relationship. Laboratory measurements of the streaming potential coupling coefficient of sediment samples at various pH and salt concentrations were

    Large VLBI telescopes undergo gravitational deformations which affect both geodetic and astronomic observations. In order to assess the extent and magnitude of such deformations and to evaluate their effect on telescopes' performances, terrestrial surveying methods can be applied to monitor the telescopes' structure at different pointing elevations. Finite Element Model analysis, laser scanner surveying, trilateration and triangulation have been applied on the telescope in Medicina to estimate i) the deformations of the primary mirror and to monitor ii) the position of the feed horn located at the primary focus and iii) the position of the vertex of the paraboloid. If detectable, these deformations modify the position of the primary focus and the signal path length and may therefore reduce the antenna gain and bias the phase of the incoming signal. We are presenting the investigations performed on the Medicina VLBI telescope, quantifying the magnitude of the deformations of the primary dish, the quadrupode and the vertex and we are also presenting an elevation dependent model for signal path corrections.

    To investigate how participants in an economic resource allocation survey construct notions of fairness. Qualitative interview study guided by interpretive grounded theory methods. Qualitative interviews were conducted with volunteer university- (n=39) and community-based (n =7) economic survey participants. INTERVENTION OR MAIN VARIABLES STUDIED: We explored how participants constructed meanings to guide or explain fair survey choices, focusing on rationales, imagery and additional desired information not provided in the survey scenarios. Data were transcribed and coded into qualitative categories. Analysis iterated with data collection iterated through three waves of interviews. Participants compared the survey dilemmas to domains outside the health system. Most compared them with other micro-level, inter-personal sharing tasks. Participants raised several fairness-relevant factors beyond need or capacity to benefit. These included age, weight, poverty, access to other options and personal responsibility for illness; illness duration, curability or seriousness; life expectancy; possibilities for sharing; awareness of other's needs; and ability to explain allocations to those affected. They also articulated a fairness principle little considered by equity theories: that everybody must get something and nobody should get nothing. Lay criteria for judging fairness are myriad. Simple scenarios may be used to investigate lay commitments to abstract principles. Although principles are the focus of analysis and inference, participants may solve simplified dilemmas by imputing extraneous features to the problem or applying unanticipated principles. These possibilities should be taken into account in the design of resource allocation surveys eliciting the views of the public. © 2012 John Wiley & Sons Ltd.

    2012-01-01

    This study aimed to better understand the causes and treatments of mucoid discharge associated with prosthetic eye wear by reviewing the literature and surveying anophthalmic patients. An anonymous questionnaire was completed by 429 prosthetic eye wearers who used visual analog scales to self-measure their discharge experience for four discharge characteristics: frequency, color, volume, and viscosity. These characteristics were analyzed with age, ethnicity, years wearing a prosthesis, eye loss cause, removal and cleaning regimes, hand-washing behavior, age of current prosthesis, and professional repolishing regimes as explanatory variables. Eighteen ocularists' Web sites containing comments on the cause and treatment of discharge were surveyed. Associations were found between discharge frequency and cleaning regimes with more frequent cleaning accompanying more frequent discharge. Color was associated with years of wearing and age, with more years of wearing and older people having less colored discharge. Volume was associated with cleaning regimes with more frequent cleaners having more volume. Viscosity was associated with cleaning regimes and years of wearing with more frequent cleaning and shorter wearing time accompanying more viscous discharge. No associations were found between discharge characteristics and ethnicity, eye loss cause, hand washing, age of current prosthesis, or repolishing regimes. Forty-seven percent of ocularists' Web sites advised that discharge was caused by surface deposits on the prosthesis, 29% by excessive handling of the prosthesis, and 24% by other causes. A standardized treatment protocol for managing discharge is lacking. More frequent prosthesis removal and cleaning was associated with more severe discharge, but the direction of cause and effect has not been established. Professional repolishing regimes had limited impact on discharge experience. Further research into the socket's response to prosthetic eye wear, including the

    The purpose of this study was to discover the frequency and type of use of online resources for continuing professional development displayed by physiotherapists in the UK. Therapists' skills, needs and frustrations using these resources were explored. With the relatively recent release and saturated use of the internet the potential presence of a skills gap between therapists at different stages of their career was also investigated. National online survey study. The online survey was carried out using the international online service 'Survey Monkey'. 774 physiotherapists from students to band 8c completed the survey. The online survey was advertised through Frontline, the Interactive Chartered Society of Physiotherapy, Journal of Physiotherapy Pain Association and cascade email through research and other networks. Most physiotherapists reported using the internet for professional purposes daily (40%) or 2 to 4 times a week (37%), with only 8% of respondents using it less than once a week. Overall the results suggest band 6 and 7 physiotherapists had the least skills and most frustrations when using online search engines. History and the nature of rapid technological advancement, specifically of the internet, appears to have created a generational skills gap within the largest group of the physiotherapy workforce band 6 and 7 therapists. Students, band 5 and band 8a therapists appear to most successfully use online resources and the reasons for this are explored. Copyright © 2012 Chartered Society of Physiotherapy.

    Full Text Available Distance education, which is a planned way of teaching in which students and instructors are brought face to face in a classroom environment in several different ways by means of technology, has started to become widespread in many fields today. In distance education, students and instructors reside in different locations. Students can learn at their pace and control their learning path, content and load of what they have learned and evaluate it. However, they should adopt strategies for effective studying in order not to waste their time and efforts. Because study skills, motivation, time management, exam preparation and coping with exam stress have an impact on students’ success. In this context, distance education students’ study skills are foregrounded in today’s widespread use of distance education. In accordance with this, this study aims to investigate some variables which are influential on the dimensions of distance education students’ motivation, time management, exam preparation and coping with exam stress. A personal information form and the Study Skills scale were used for data collection. This study was designed in survey model and SPSS16.0 statistical package program was used for the statistical analyses of the research data. The research findings were discussed in line with the literature and some suggestions were presented for further research and researchers.

    The accidents that occurred at the Fukushima Daiichi Nuclear Power Plant after the Great East Japan Earthquake on 11 March 2011 have resulted in long-term, ongoing anxiety among the residents of Fukushima, Japan. Soon after the disaster, Fukushima Prefecture launched the Fukushima Health Management Survey to investigate long-term low-dose radiation exposure caused by the accident. Fukushima Medical University took the lead in planning and implementing this survey. The primary purposes of this survey are to monitor the long-term health of residents, promote their future well-being, and confirm whether long-term low-dose radiation exposure has health effects. This report describes the rationale and implementation of the Fukushima Health Management Survey. This cohort study enrolled all people living in Fukushima Prefecture after the earthquake and comprises a basic survey and 4 detailed surveys. The basic survey is to estimate levels of external radiation exposure among all 2.05 million residents. It should be noted that internal radiation levels were estimated by Fukushima Prefecture using whole-body counters. The detailed surveys comprise a thyroid ultrasound examination for all Fukushima children aged 18 years or younger, a comprehensive health check for all residents from the evacuation zones, an assessment of mental health and lifestyles of all residents from the evacuation zones, and recording of all pregnancies and births among all women in the prefecture who were pregnant on 11 March. All data have been entered into a database and will be used to support the residents and analyze the health effects of radiation. The low response rate (<30%) to the basic survey complicates the estimation of health effects. There have been no cases of malignancy to date among 38 114 children who received thyroid ultrasound examinations. The importance of mental health care was revealed by the mental health and lifestyle survey and the pregnancy and birth survey. This long

    The goal of this study was to investigate the efficacy of curriculum and instructional techniques in a technical core course to create a more conducive learning environment for women. The technical core course introduced technology majors to mechanical systems, electronics, and fluid power principles through lectures and laboratory work. Female students already enrolled in the department and female alumnae of the program were surveyed. The students' responses to the survey showed that although the female participants in the study were pleased with the instructors, the curriculum, and the instruction they received, they had recommendations for modifying the instruction.

    The U.S. Geological Survey and the National Aeronautics and Space Administration are cooperatively investigating the utility of unmanned vehicles for near-real-time autonomous surveys of geophysical data collection. Initially focused on unmanned ground vehicle collection of magnetic data, this cooperative effort has brought unmanned surveying, precision guidance, near-real-time communication, on-the-fly data processing, and near-real-time data interpretation into the realm of ground geophysical surveying, all of which offer advantages over current methods of manned collection of ground magnetic data. An unmanned ground vehicle mission has demonstrated that these vehicles can successfully complete missions to collect geophysical data, and add advantages in data collection, processing, and interpretation. We view the current experiment as an initial phase in further unmanned vehicle data-collection missions, including aerial surveying.

    2017-09-01

    The grounded-wire transient electromagnetic (TEM) surveying is often performed along the equatorial direction with its observation lines paralleling to the transmitting wire with a certain transmitter-receiver distance. However, such method takes into account only the equatorial component of the electromagnetic field, and a little effort has been made on incorporating the other major component along the transmitting wire, here denoted as axial field. To obtain a comprehensive understanding of its fundamental characteristics and guide the designing of the corresponding observation system for reliable anomaly detection, this study for the first time investigates the axial electric field from three crucial aspects, including its decay curve, plane distribution, and anomaly sensitivity, through both synthetic modeling and real application to one major coal field in China. The results demonstrate a higher sensitivity to both high- and low-resistivity anomalies by the electric field in axial direction and confirm its great potentials for robust anomaly detection in the subsurface.

    Full Text Available In a 2016 survey of 704 National Science Foundation (NSF Biological Sciences Directorate principal investigators (BIO PIs, nearly 90% indicated they are currently or will soon be analyzing large data sets. BIO PIs considered a range of computational needs important to their work, including high performance computing (HPC, bioinformatics support, multistep workflows, updated analysis software, and the ability to store, share, and publish data. Previous studies in the United States and Canada emphasized infrastructure needs. However, BIO PIs said the most pressing unmet needs are training in data integration, data management, and scaling analyses for HPC-acknowledging that data science skills will be required to build a deeper understanding of life. This portends a growing data knowledge gap in biology and challenges institutions and funding agencies to redouble their support for computational training in biology.

    To date, there is no assessment of more than one survey used for a clinical research study that address subjects with and without symptoms related to accommodative or binocular vision disorders. Thus, the purpose of this study was to investigate two different surveys - CISS and Conlon for the same subject group and analyse also critical visual function parameters. Monocular and binocular accommodative response for 20 subjects was measured for dominant eye with openfield infrared autorefractometer (Shin-Nippon SRW-5000) at three distances (24 cm, 30 cm and 40 cm). Subjects were divided into symptomatic and asymptomatic group using cut off score 21 for CISS and 20 for Conlon survey. We found positive exponential growth relationship between CISS and Conlon scores (R² = 0.7), but separation between symptomatic and asymptomatic group differed significantly depending on which survey was used. We found positive correlation between Conlon score and exophoria at 30 cm (r=0.41, p=0.01) and 24 cm (r=0.27, p=0.03). Relationship between subjective symptoms and following clinical parameters - accommodation lag (r history and tool to measure patient satisfaction and results of treatment effectiveness instead of using them for clinical trials as a criteria to divide symptomatic and asymptomatic group.

    Quasar outflows are hypothesized to regulate the growth of a quasar's host galaxy and the supermassive black hole (SMBH) itself. Thus, understanding the physics of these outflows is imperative to understanding galactic evolution. The physical properties of these outflows, such as density, radial distance from the SMBH, and kinetic energy can be investigated by measuring both the strength and shape variability of broad absorption lines (BALs) in quasar spectra. However, the accuracy of physical properties calculated using BAL variability methods is limited by the time resolution of the observations. Recent spectral data from the Sloan Digital Sky Survey Reverberation Mapping program (SDSS-RM) provides a novel opportunity to investigate the short-term BAL variability of many quasars at many epochs. The SDSS-RM program took many epochs of spectra for a large sample of quasars over a period of several years, many of which exhibit BALs. The median rest-frame time resolution of these observations is roughly 2 days, in contrast to previous large-sample studies, which typically have time spacing on the order of hundred of days. We are using the SDSS-RM dataset to conduct a BAL variability study that will further constrain outflow properties and provide significant insights into the variability mechanisms of quasar outflows. We are searching for variability in BALs on timescales of less than 2 days among our sample of 22 quasars and determining whether this behavior is common among quasars. We are also investigating the general short-term (less than 10 days) variability characteristics of the entire sample. We will present preliminary results from this study and the possible implications to our understanding of quasar outflows.

    Full Text Available The investigation of multiple sources in household water management is considered overly complicated and time consuming using paper and pen interviewing (PAPI. We assess the advantages of computer-assisted personal interviewing (CAPI in Pacific Island Countries (PICs. We adapted an existing PAPI survey on multiple water sources and expanded it to incorporate location of water use and the impacts of extreme weather events using SurveyCTO on Android tablets. We then compared the efficiency and accuracy of data collection using the PAPI version (n = 44 with the CAPI version (n = 291, including interview duration, error rate and trends in interview duration with enumerator experience. CAPI surveys facilitated high-quality data collection and were an average of 15.2 min faster than PAPI. CAPI survey duration decreased by 0.55% per survey delivered (p < 0.0001, whilst embedded skip patterns and answer lists lowered data entry error rates, relative to PAPI (p < 0.0001. Large-scale household surveys commonly used in global monitoring and evaluation do not differentiate multiple water sources and uses. CAPI equips water researchers with a quick and reliable tool to address these knowledge gaps and advance our understanding of development research priorities.

  1. How Well Do Survey Studies Capture Alcohol's Harm to Others?

    Science.gov (United States)

    Rossow, Ingeborg

    2015-01-01

    Empirical studies assessing alcohol's harm to others very often rely on population survey data. This study addresses some of the problems and challenges in using survey data for this purpose. Such problems include the limited capacity of population surveys in identifying infrequent harm and long-term consequences of drinking. Moreover, the drinker may report the alcohol-related harm or the person being harmed may report the damage. However, irrespective of who reports the harm, causal attribution to drinking is problematic. Challenges for future population surveys to address alcohol's harm to others include the need for improved models and understanding of complex mechanisms to guide empirical studies within the broad range of harm. Study designs other than cross-sectional surveys, such as longitudinal study designs and combinations of population surveys and other data sources, are likely to overcome some of the identified problems in current population surveys of alcohol's harm to others.

  2. THE FLORENCE BAPTISTERY: 3-D SURVEY AS A KNOWLEDGE TOOL FOR HISTORICAL AND STRUCTURAL INVESTIGATIONS

    2016-06-01

    Full Text Available The Baptistery of San Giovanni is one of the most important pieces of architecture in Florence. It is an octagonal building, encrusted with marble both internally and externally (including the pyramidal roof and covered inside by a magnificent dome with sparkling gold mosaics. During Dante’s time, it appeared much older than the other monuments, so its origins were considered as hailing straight from Florence’s most remote and mythical history. Even though we have much more data now, scholars still disagree over the interpretations on the origin and construction sequence of the monument. Survey has always been considered a main instrument for understanding historical architecture, mostly from constructional and structural points of view. During the last century, the Baptistery was surveyed using both traditional techniques and the most up-to-date instruments available at the time, such as topography, close-range photogrammetry and laser scanning. So, a review of those early applications, even if partial or isolated, can significantly attest to the state of the art and evolution of survey techniques. During recent years, the Opera di Santa Maria del Fiore promoted new research and a wide range of diagnostic investigations aimed at acquiring greater knowledge of the monument in anticipation of the cleaning and restoration of the outer wall surfaces during 2015. Among this research, GeCo Lab carried out a new systematic and complete laser scanner survey of the whole Baptistery, acquiring data for the more inaccessible parts that were given little attention during other survey campaigns. First of all, the paper analyses recent contributions given by instrumental surveys in advancing knowledge of the building, with references to the cutting-edge techniques and measurement tools used at the time. Then, it describes the new survey campaign, illustrating the approach followed in the planning, data acquisition and data elaboration phases; finally, it

    Since land surveyors working alongside live traffic encounter unique safety challenges there is a great need for innovative and effective traffic control devices (TCDs) that alert motorists approaching short-term land surveying work sites. Unlike the volume of research that has been completed on traditional work zones, however, there is a limited amount of information that has been collected on how motorists respond to TCDs at land surveying work sites. This article aims to fill the void by investigating motorists' behaviors in response to the use of 2 supplementary TCDs at land surveying work sites: portable plastic rumble strips (PPRS) and warning lights. Extensive field tests were conducted at various land surveying work sites on 2-lane 2-way urban roadways in New Jersey. Scenarios with and without the use of the supplemental TCDs were designed. Motorists' behavior changes were then statistically examined by using surrogate safety measures including mean speed, speed variance, speed limit compliance, and braking action. Statistical analyses showed that the traffic speed variations did not significantly increase when the selected supplemental TCD was used; rather, motorists significantly reduced their driving speed. When warning lights and PPRS were separately deployed at the land surveying work sites the average reduction in mean speed was 6.7 and 15.2 percent, respectively. The mean speed was reduced by 19.7 percent when both of these supplementary TCDs were used. Logistic regression models developed to examine the speeding and braking behavior also showed that motorists were more likely to comply with the speed limit and increase their braking rate when the selected TCDs were used. The use of supplemental TCDs can greatly contribute to the changes in motorists' behaviors at surveying work sites. The changes in motorists' driving behaviors imply that the motorists reacted favorably to the deployed TCDs at the land-surveying work sites.

  4. Canonical Word Order of Japanese Ditransitive Sentences: A Preliminary Investigation through a Grammaticality Judgment Survey

    Directory of Open Access Journals (Sweden)

    Yasumasa Shigenaga

    2014-04-01

    Full Text Available There have been three competing analyses regarding the canonical word order of Japanese ditransitive sentences: a “S-ga IO-ni DO-o V” is the canonical word order rather than “S-ga DO-o IO-ni V”, b both word orders are canonical, and c the canonical word order depends on the type of the verb. The present study attempted to examine which of the three analyses might be most plausible through a grammaticality judgment survey. Twenty-seven native speakers of Japanese responded to a survey which consisted of three sections. While the data from one of the sections conformed to analysis a above, the results of the two other sections remained inconclusive. A future study with a larger number of items and more refined survey methods, along with more studies from structural and psycholinguistic perspectives, would be necessary to clarify the point.

    1997-01-01

    Full Text Available A survey was mailed to all institutions in Canada licensed to use radiopharmaceuticals. Questions addressed meal type; mode of preparation; and means, ranges and SD of emptying times. Seventy-eight per cent of 222 facilities responded, including all 55 teaching centres. Eighty-five per cent of teaching and 56% of nonteaching centres perform solid phase gastric emptying studies (GES. The majority use 99mTc sulphur colloid (Tc-SC added to eggs before cooking as the standard meal. Twenty-five per cent of teaching and 21% of nonteaching centres perform liquid phase GES. Most use a watery solution of 111In-diethylenetriamine pentaacetic acid. Gastric emptying for solid phase GES, expressed as time for 50% emptying (mean t½, varied from 42 to 105 mins for centres using the Tc-SC egg meal. Twenty-eight per cent of teaching centres used ±2 SD to define their normal range, 26% used ±1 SD, 6% used ±1.5 SD, and 40% did not know the number of SD used. Twenty per cent of non-teaching centres used ±2 SD, 12% used ±1 SD and 68% did not know how many SD were used. For liquid phase GES, mean t½ varied from 20 to 60 mins. Eighteen per cent of centres used healthy volunteers to establish or validate normal ranges. There is substantial variability among the normal ranges for radionuclide solid and liquid phase GES in both teaching and nonteaching centres across Canada. A minority of facilities have established or validated their own normal ranges in healthy volunteers. There is a need for a more standardized protocol and range of normal, with internal validation by each institution.

  6. Markets and morals: an experimental survey study.

    Full Text Available Most societies prohibit some market transactions based on moral concerns, even when the exchanges would benefit the parties involved and would not create negative externalities. A prominent example is given by payments for human organs for transplantation, banned virtually everywhere despite long waiting lists and many deaths of patients who cannot find a donor. Recent research, however, has shown that individuals significantly increase their stated support for a regulated market for human organs when provided with information about the organ shortage and the potential beneficial effects a price mechanism. In this study we focused on payments for human organs and on another "repugnant" transaction, indoor prostitution, to address two questions: (A Does providing general information on the welfare properties of prices and markets modify attitudes toward repugnant trades? (B Does additional knowledge on the benefits of a price mechanism in a specific context affect attitudes toward price-based transactions in another context? By answering these questions, we can assess whether eliciting a market-oriented approach may lead to a relaxation of moral opposition to markets, and whether there is a cross-effect of information, in particular for morally controversial activities that, although different, share a reference to the "commercialization" of the human body. Relying on an online survey experiment with 5,324 U.S. residents, we found no effect of general information about market efficiency, consistent with morally controversial markets being accepted only when they are seen as a solution to a specific problem. We also found some cross-effects of information about a transaction on the acceptance of the other; however, the responses were mediated by the gender and (to a lesser extent religiosity of the respondent--in particular, women exposed to information about legalizing prostitution reduced their stated support for regulated organ payments.

    Pain neuroscience education (PNE) has gained considerable attention in research. Three systematic reviews have shown increasing efficacy of PNE decreasing pain, disability, pain catastrophization, movement restrictions, and healthcare utilization. In the development of any new therapeutic approach, it is proposed that there are three stages: development, validation, and implementation. To date, the development and validation of PNE have been well-established. The third stage, implementation, however, lacks when it comes to PNE. The purpose of this study was to survey physical therapists (PT) on their experience and implementation of PNE, following a 15-hour PNE class. Upon development and validation of a PT-PNE survey, a random sample of PTs was invited to take the online survey. Two hundred and eighty-six PTs (female 56%) completed the PNE questionnaire. Ninety-one percent of PTs reported not being taught PNE in PT school. PT's are applying PNE into clinical practice to a variety of patients, experience outcomes in line with the current best-evidence, but struggle establishing which patients are ideal for PNE. The same five patient characteristics associated with success were also associated with failure, albeit in a different ranking order. This finding highlight the need to further investigate the factors associated with success and failure of PNE.

    2014-03-06

    Genitourinary investigations are performed on a large proportion of middle-aged and older men and the majority undergo investigations for prostate issues. The effects that genitourinary disease can have on men depend on the type of problem, investigations required and treatment including impotence, gynaecomastia and urinary incontinence that have lasting devastating physical, social and psychological effects. The aim was to explore older men's experience and views of intimate and intrusive genitourinary investigations and specifically to develop hypotheses and theories concerning gender and sexuality issues in intimate genitourinary investigations. Written informed consent was obtained for this qualitative study. Data were collected through one-off, semi-structured interviews involving 15 men in the first year following patient's last urological procedure. Initially, multiple themes were identified and when analysed further concepts were repeatedly present. As the urological investigations were limited to men, gender and sexuality became prominent issues in the data. On analysis, the term parasexuality appeared to explain the dynamic of the situation. Parasexuality is a modified form of sexuality which is channelled and limited to maintain propriety. This was not expressed as sexuality in its overt, explicit sense, but instead a type of covert sexuality where professional boundaries are maintained but nonetheless undercurrents remain. This managed version of sexuality created a common currency by which interactions between staff and patients could take place safely. Feeding into parasexuality were gender role stereotypes and for some of the participants this reflected their own experience, context, historical and cultural norms. Intimate contact in the form of exposure and handling of the participants' genitalia during the investigations particularly challenged the boundaries of parasexuality. In order to remain parasexual, many of the participants suppressed their

    Since 2000, the German Federal Institute for Geosciences and Natural Resources (BGR) carried out several airborne geophysical surveys in Northern Germany to investigate the coastal areas of the North Sea and some of the North and East Frisian Islands. Several of those surveys were conducted in cooperation with the Leibniz Institute for Applied Geophysics (LIAG). Two helicopter-borne geophysical systems were used, namely the BGR system, which collects simultaneously frequency-domain electromagnetic, magnetic and radiometric data, and the SkyTEM system, a time-domain electromagnetic system developed by the University of Aarhus. Airborne geophysical surveys enable to investigate huge areas almost completely with high lateral resolution in a relatively short time at economic cost. In general, the results can support geological and hydrogeological mapping. Of particular importance are the airborne electromagnetic results, as the surveyed parameter - the electrical conductivity - depends on both lithology and groundwater status. Therefore, they can reveal buried valleys and the distribution of sandy and clayey sediments as well as salinization zones and fresh-water occurrences. The often simultaneously recorded magnetic and radiometric data support the electromagnetic results. Lateral changes of Quaternary and Tertiary sediments (shallow source - several tens of metres) as well as evidences of the North German Basin (deep source - several kilometres) are revealed by the magnetic results. The radiometric data indicate the various mineral compositions of the soil sediments. This BGR/LIAG project aims to build up a geophysics data base (http://geophysics-database.de/) which contains all airborne geophysical data sets. However, the more significant effort is to create a reference data set as basis for monitoring climate or man-made induced changes of the salt-water/fresh-water interface at the German North Sea coast.

    2015-12-01

    We conducted a survey to assess the perspectives of principal investigators and Institutional Review Board (IRB) members on the impact of the IRB structure on the conduct of research and innovative therapy, defined as a nonstandard treatment intended to enhance the well-being of an individual patient. Although investigators and IRB members agreed that the IRB provides adequate protection to study subjects (97% vs. 100%) and an ethically insightful review (88% vs. 100%), a third of clinical investigators felt that the IRB review process limits clinical innovation, in comparison with only 4% of IRB representatives. Limitations of the current IRB review process were explored. We propose several measures to improve the IRB review process while maintaining the protection of human research subjects, including the use of centralized IRBs, the opening of IRB meetings to investigators, the development of metrics and outcome measures for the IRB, and the promotion of guidelines that distinguish research and innovative therapy. © The Author(s) 2015.

    Full Text Available Background: Clinical research in India experienced dramatic changes with series of stringent guidelines introduced by regulatory authorities. These guidelines posed significant challenges for the clinical trial industry. Objective: To assess the perceptions and opinion of Indian Investigators about the new regulatory guidelines. Methods: We developed a survey questionnaire on recent regulatory guidelines which was hosted on a web portal. Seventy-three investigators from India participated in the survey. Results: Central registration of Ethics Committees (ECs was agreed by 90.1% participants, 76.8% participants agreed to compensation of subjects for study related Serious Adverse Events (SAE's. The compulsion to include government sites in clinical trials was not agreed by 49.3% participants while 21.2% agreed to it. Restriction on a number of trials per investigator was agreed by 49.3% of participants while 40.9% disagreed. Participants (50.7% disagreed to the introduction of audio-video (AV recording of informed consent, 36.6% agreed and 12.7% were neutral. Discussion: Participants observed that post central registration; ECs have improved systems with adequate member composition, functional Standard Operating Procedures, and timely approvals. Participants agreed that compensation of study related SAE's would assure subject protection and safety. The introduction of AV consenting was strongly debated sighting sociocultural issues in the implementation of the same. Conclusion: Participants endorsed guidelines pertaining to the central registration of ECs, SAE related compensation. Restrictions on a number of trials per investigator and AV consenting were debated ardently. The response of the survey participants who are clinical trial investigators in India showed general acceptance, effectiveness and anticipated compliance to the new regulatory guidelines.

  13. Designing occupancy studies: general advice and allocating survey effort

    1. The fraction of sampling units in a landscape where a target species is present (occupancy) is an extensively used concept in ecology. Yet in many applications the species will not always be detected in a sampling unit even when present, resulting in biased estimates of occupancy. Given that sampling units are surveyed repeatedly within a relatively short timeframe, a number of similar methods have now been developed to provide unbiased occupancy estimates. However, practical guidance on the efficient design of occupancy studies has been lacking. 2. In this paper we comment on a number of general issues related to designing occupancy studies, including the need for clear objectives that are explicitly linked to science or management, selection of sampling units, timing of repeat surveys and allocation of survey effort. Advice on the number of repeat surveys per sampling unit is considered in terms of the variance of the occupancy estimator, for three possible study designs. 3. We recommend that sampling units should be surveyed a minimum of three times when detection probability is high (> 0.5 survey-1), unless a removal design is used. 4. We found that an optimal removal design will generally be the most efficient, but we suggest it may be less robust to assumption violations than a standard design. 5. Our results suggest that for a rare species it is more efficient to survey more sampling units less intensively, while for a common species fewer sampling units should be surveyed more intensively. 6. Synthesis and applications. Reliable inferences can only result from quality data. To make the best use of logistical resources, study objectives must be clearly defined; sampling units must be selected, and repeated surveys timed appropriately; and a sufficient number of repeated surveys must be conducted. Failure to do so may compromise the integrity of the study. The guidance given here on study design issues is particularly applicable to studies of species

  14. Neuroscience Investigations: An Overview of Studies Conducted

    The neural processes that mediate human spatial orientation and adaptive changes occurring in response to the sensory rearrangement encountered during orbital flight are primarily studied through second and third order responses. In the Extended Duration Orbiter Medical Project (EDOMP) neuroscience investigations, the following were measured: (1) eye movements during acquisition of either static or moving visual targets, (2) postural and locomotor responses provoked by unexpected movement of the support surface, changes in the interaction of visual, proprioceptive, and vestibular information, changes in the major postural muscles via descending pathways, or changes in locomotor pathways, and (3) verbal reports of perceived self-orientation and self-motion which enhance and complement conclusions drawn from the analysis of oculomotor, postural, and locomotor responses. In spaceflight operations, spatial orientation can be defined as situational awareness, where crew member perception of attitude, position, or motion of the spacecraft or other objects in three-dimensional space, including orientation of one's own body, is congruent with actual physical events. Perception of spatial orientation is determined by integrating information from several sensory modalities. This involves higher levels of processing within the central nervous system that control eye movements, locomotion, and stable posture. Spaceflight operational problems occur when responses to the incorrectly perceived spatial orientation are compensatory in nature. Neuroscience investigations were conducted in conjunction with U. S. Space Shuttle flights to evaluate possible changes in the ability of an astronaut to land the Shuttle or effectively perform an emergency post-landing egress following microgravity adaptation during space flights of variable length. While the results of various sensory motor and spatial orientation tests could have an impact on future space flights, our knowledge of

    This paper describes a remotely operated investigation system developed by combining a modern leisure-use fish finder and an unmanned watercraft to survey water bottom topography and other data related to bottom materials. Current leisure-use fish finders have strong depth sounding capabilities and can provide precise sonar images and bathymetric information. Because these sonar instruments are lightweight and small, they can be used on unmanned small watercraft. With the developed system, an operator can direct the heading of an unmanned watercraft and monitor a PC display showing real-time positioning information through the use of onboard equipment and long-distance communication devices. Here, we explain how the system was developed and demonstrate the use of the system in an area of submerged woods in a lake. The system is low cost, easy to use, and mobile. It should be useful in surveying areas that have heretofore been hard to investigate, including remote, small, and shallow lakes, for example, volcanic and glacial lakes.

    The ear is a key facial feature and yet few studies have previously assessed ear aesthetics. This study aimed to assess the anatomical components of the ear that have the greatest impact on the perception of ear aesthetics. Three photographs of a male adult ear (close-up, lateral, posterior) were digitally manipulated such that in each, 1 anatomical element of the ear was either enlarged or reduced. A complete set of 16 photographs including a repeat of the original ear as a control were randomized and entered into an online survey that required respondents to rate the attractiveness of each ear on a scale of 1 (least attractive) to 10 (most attractive). The survey was disseminated using email and social media. A total of 248 responses were received, 155 women and 92 men. Respondents were grouped by demographics of age and occupation. Reducing (R) or enlarging (E) the helix (R, P = 0.0256; E, P = 0.003), concha (R, P = 0.0002; E, P = aesthetics. Furthermore, this study has proven the usefulness of conducting research using viral online surveys.

    In the thesis we study close pairs of galaxies with the aim of understanding the influence of gravitational interaction on nuclear activity and star formation of paired galaxies. For this purpose we investigate dependences of integral parameters of galaxies, their star formation and properties of nuclei on kinematic parameters of systems and their large-scale environment. The thesis has an introduction, three main chapters, a summary, lists of abbreviations and references, and three appendices. In the first chapter, the methods of selection of sample of pairs of galaxies and measurements of physical parameters of the First Byurakan Survey (Markarian) galaxies and their neighbors are presented, and the databases in appendices A and B are described, which contain parameters of neighbors of Markarian galaxies measured by us, and the parameters of pairs having Markarian galaxies, based on the Sloan Digital Sky Survey (SDSS) data. The selection effects of sample of pairs are discussed, and the statistical comparison of Markarian galaxies and their neighbors is done. The results of statistical study of star formation and activity of nuclei in pairs having Markarian galaxies are presented, as well as the correlations between properties of galaxies in pairs and the physical mechanisms behind them. In the second chapter, the results of statistical study of the Second Byurakan Survey (SBS) galaxies and their neighbors, and star formation and activity of nuclei in those pairs are presented and discussed. In the third chapter, possibilities of using supernovae as indicators of star formation are discussed, the sample of supernovae in pairs of galaxies is presented, and study of star formation in pairs of interacting galaxies by means of that sample of supernovae is done. Also а conclusion about the nature of progenitors of different types of supernovae is made. The short summary of main results of the study concludes the thesis. The thesis has 158 pages.

    Culham Center for Fusion Energy (CCFE) in UK has been contracted to undertake a second Deuterium-Tritium Experiment (DTE2) using Join European Torus (JET) in 2017, in support of technical developments for the ITER project. In order to manage risks of delay or early project termination CCFE has adopted a risk based inspection (RBI) process to identify the systems which could influence the successful delivery of DTE2 and in turn to identify by a basic risk assessment process those systems or components which require mitigating action in order to minimize risk. In this context, the primary purpose of the RBI is to address issues of reliability and satisfactory functionality in a similar way to that which a power plant operator would take to address its commercial risks in the event of loss of generating capacity. The objective of this presentation is describe the activities developed for Idom to deliver the survey, interviews and risk assessment of different systems of JET with the aim to identify the critical components and system that could affect the operation of JET during the DTE2 experiment.

    Full Text Available Abstract Background Administrative and survey data are two key data sources for population-based research about chronic disease. The objectives of this methodological paper are to: (1 estimate agreement between the two data sources for irritable bowel syndrome (IBS and compare the results to those for inflammatory bowel disease (IBD; (2 compare the frequency of IBS-related diagnoses in administrative data for survey respondents with and without self-reported IBS, and (3 estimate IBS prevalence from both sources. Methods This retrospective cohort study used linked administrative and health survey data for 5,134 adults from the province of Manitoba, Canada. Diagnoses in hospital and physician administrative data were investigated for respondents with self-reported IBS, IBD, and no bowel disorder. Agreement between survey and administrative data was estimated using the κ statistic. The χ2 statistic tested the association between the frequency of IBS-related diagnoses and self-reported IBS. Crude, sex-specific, and age-specific IBS prevalence estimates were calculated from both sources. Results Overall, 3.0% of the cohort had self-reported IBS, 0.8% had self-reported IBD, and 95.3% reported no bowel disorder. Agreement was poor to fair for IBS and substantially higher for IBD. The most frequent IBS-related diagnoses among the cohort were anxiety disorders (34.4%, symptoms of the abdomen and pelvis (26.9%, and diverticulitis of the intestine (10.6%. Crude IBS prevalence estimates from both sources were lower than those reported previously. Conclusions Poor agreement between administrative and survey data for IBS may account for differences in the results of health services and outcomes research using these sources. Further research is needed to identify the optimal method(s to ascertain IBS cases in both data sources.

    Background. Improving mentorship may help decrease the shortage of young investigators (graduate students, postdoctoral fellows, and new investigators) available to work as independent researchers in cardiovascular and respiratory health. Objectives. To determine (1) the mentoring practices for trainees affiliated with the Canadian Institutes of Health Research (CIHR), Institute of Circulatory and Respiratory Health (ICRH), (2) the positive attributes of mentors, and (3) the recommendations regarding what makes good mentorship. Methods. We conducted a survey and descriptive analysis of young investigators with a CIHR Training and Salary Award from 2010 to 2013 or who submitted an abstract to the ICRH 2014 Young Investigators Forum. Clinicians were compared to nonclinicians. Results. Of 172 participants, 7.0% had no mentor. Only 43.6% had defined goals and 40.7% had defined timelines, while 54.1% had informal forms of mentorship. A significant proportion (33.1%) felt that their current mentorship did not meet their needs. Among clinicians, 22.2% would not have chosen the same mentor again versus 11.4% of nonclinicians. All participants favored mentors who provided guidance on career and work-life balance. Suggestions for improved mentoring included formal mentorship, increased networking, and quality assurance. Conclusion. There is an important need to improve mentoring in cardiovascular and respiratory health.

    With advances such as next-generation sequencing (NGS) increasing understanding of the basis of cancer and its response to treatment, NCCN believes it is important to understand how molecular profiling/diagnostic testing is being performed and used at NCCN Member Institutions and their community affiliates. The NCCN Oncology Research Program's Investigator Steering Committee and the NCCN Best Practices Committee gathered baseline information on the use of cancer-related molecular testing at NCCN Member Institutions and community members of the NCCN Affiliate Research Consortium through 2 separate surveys distributed in December 2013 and September 2014, respectively. A total of 24 NCCN Member Institutions and 8 affiliate sites provided quantitative and qualitative data. In the context of these surveys, "molecular profiling/diagnostics" was defined as a panel of at least 10 genes examined as a diagnostic DNA test in a Clinical Laboratory Improvement Amendments (CLIA)-certified laboratory. Results indicated that molecular profiling/diagnostics are used at 100% of survey respondents' institutions to make patient care decisions. However, challenges relating to reimbursement, lack of data regarding actionable targets and targeted therapies, and access to drugs on or off clinical trials were cited as barriers to integration of molecular profiling into patient care. Frameworks for using molecular diagnostic results based on levels of evidence, alongside continued research into the predictive value of biomarkers and targeted therapies, are recommended to advance understanding of the role of genomic biomarkers. Greater evidence and consensus regarding the clinical and cost-effectiveness of molecular profiling may lead to broader insurance coverage and increased integration into patient care.

    The EarthLabs Climate project, an NSF-Discovery Research K12 program, has developed a suite of three online classroom-ready modules: Climate and the Cryosphere; Climate and the Carbon Cycle; and Climate and the Biosphere. The EarthLabs Climate project included week-long professional development workshops during June of 2012 and 2013 in Texas and Mississippi. Evaluation of the 2012 and 2013 workshops included participant self-reported learning levels in many areas of climate science. Teachers' answers indicated they had increased their understanding of the topics addressed in the workshops. However, the project team was interested in refining the evaluation process to determine exactly those areas of climate science in which participants increased content knowledge and ameliorated misconceptions. Therefore, to enhance the investigation into what teachers got out of the workshop, a pre-test/post-test design was implemented for 2013. In particular, the evaluation team was interested in discovering the degree to which participants held misconceptions and whether those beliefs were modified by attendance at the workshops. For the 2013 workshops, a registration survey was implemented that included the Climate Concept Inventory (a climate content knowledge quiz developed by the education research team for the project). The multiple-choice questions are also part of the pre/post student quiz used in classrooms in which the EarthLabs Climate curriculum was implemented. Many of the questions in this instrument assess common misconceptions by using them as distractors in the multiple choice options. The registration survey also asked respondents to indicate their confidence in their answer to each question, because, in addition to knowledge limitations, lack of confidence also can be a barrier to effective teaching. Data from the registration survey informed workshop managers of the topic content knowledge of participants, allowing fine-tuning of the professional development

    Full Text Available Sustainability education (SE is included in school curricula to integrate the principles, values, and practices of sustainable development (SD into all education. This study investigates lower secondary school subject teachers as educators for sustainability. A survey was used to study the perceptions of 442 subject teachers from 49 schools in Finland. There were significant differences between the subject teachers’ perceptions of their SE competence, and the frequency with which they used different dimensions of SE (ecological, economic, social, well-being, cultural in their teaching varied. Teachers’ age had a small effect, but gender, school, and its residential location were nonsignificant factors. Teachers could be roughly classified into three different subgroups according to their perceptions of the role of SE in their teaching; those who considered three SE dimensions rather often and used holistic sustainability approaches in their teaching (biology, geography, history; those who considered two or three dimensions often but were not active in holistic teaching (mother tongue, religion, visual arts, crafts, music, physical and health education, and home economics and those who used one SE dimension or consider only one holistic approach in their teaching (mathematics, physics, chemistry and language. Subject teachers’ awareness of their SE competence is important to encourage them to plan and implement discipline-based and interdisciplinary SE in their teaching. The specific SE expertise of subject teachers should be taken into account in teacher training and education.

  15. The Impact of Targeted Data Collection on Nonresponse Bias in an Establishment Survey: A Simulation Study of Adaptive Survey Design

    Directory of Open Access Journals (Sweden)

    McCarthy Jaki

    2017-09-01

    Full Text Available Nonresponse rates have been growing over time leading to concerns about survey data quality. Adaptive designs seek to allocate scarce resources by targeting specific subsets of sampled units for additional effort or a different recruitment protocol. In order to be effective in reducing nonresponse, the identified subsets of the sample need two key features: 1 their probabilities of response can be impacted by changing design features, and 2 once they have responded, this can have an impact on estimates after adjustment. The National Agricultural Statistics Service (NASS is investigating the use of adaptive design techniques in the Crops Acreage, Production, and Stocks Survey (Crops APS. The Crops APS is a survey of establishments which vary in size and, hence, in their potential impact on estimates. In order to identify subgroups for targeted designs, we conducted a simulation study that used Census of Agriculture (COA data as proxies for similar survey items. Different patterns of nonresponse were simulated to identify subgroups that may reduce estimated nonresponse bias when their response propensities are changed.

  16. Magnetic investigations for studying planetary interiors

    Directory of Open Access Journals (Sweden)

    A. De Santis

    1994-06-01

    Full Text Available Most of the magnetic methods used for investigating planetary interiors are based on the reasonable hypothesis that the mechanism for the origin of the field is an Earth-like hydromagnetic dynamo: in this case the planet has an electrically conducting fluid shell within it as in the case of the Earth's core. The present paper describes several techniques of planetary magnetic investigation which give important clues on the internal constitution of planets. Some considerations on the possible mechanisms for maintaining a dynamo and simple concepts with the help of a few non-dimensional numbers are also introduced and discussed. Then some fundamental relationships are given in order to relate the planetary magnetism to other physical parameters, such as angular rotation, core dimensions etc. It finally summarizes some results available for the planets of the Solar System.

    Research has shown that osteopathic manipulative treatment (OMT) in hospitalized patients can shorten hospital length of stay. However, hospital staff may be unfamiliar with OMT and its use in this setting. To assess a hospital staff's knowledge of osteopathic manipulative medicine (OMM) and investigate whether there is a correlation between job category and knowledge of OMM. The study used a 13-item survey that was developed using SurveyMonkey. A brief description stating the purpose of the survey with a hyperlink to the survey was sent in an e-mail to the employee LISTSERV at Good Samaritan Regional Medical Center. This LISTSERV included all 1933 employees at the medical center. After 10 days the survey was closed and the responses were collected and interpreted by a statistician and the primary investigator. Incomplete surveys were included. A total of 474 employees (24.5%) returned the survey. Of these respondents, 267 (66.9%) responded that OMM could be done in the hospital. Only 97 respondents (24.6%) reported seeing OMM performed in the hospital. Physicians had the highest awareness of OMM (53.7%), compared with all other employees (7%). An overall lack of knowledge exists regarding OMM among hospital staff, especially nonphysician employees, at a medical clinic.

    , unfavorable soils, or past land use. How much is due to the land use is still controversial, resulting in many questions relative to planning corrective measures. The problem facing the early administrators of the Taylor Grazing Act to bring about proper use and conservation of the public domain was a difficult one because of the lack of records on actual grazing use in animal-unit months of the qualified allottees and the lack of data on treatment practices in an arid area. Reduction of grazing was imperative in some localities, but generally, it could not be brought about as rapidly as it should have been. Numbers of animal units in the grazing districts were reduced from about 3.6 million in 1941 to about 3.2 million in 1964, whereas the areas included in districts was increased about 3 percent. Reductions are still being made in certain areas where deterioration is evident. One of the earliest activities connected with management of the range was the development of water supplies to facilitate the distribution of grazing. The investigations needed for such development formed a large part of the early work in the Soil and Moisture program of the Geological Survey and has continued to be a major activity to the present time. Most of the work has involved investigations of sites for wells but has included also the investigation of proposed spring developments and collection of hydrologic data for use in reservoir design. Well-site investigations have been of two general types: (1) the investigation of a site selected by the land administration agency, and (2) an areal investigation covering entire grazing districts or units thereof. In each type of investigation, a study is made of the geology and the recharge conditions. Reports are prepared giving estimates of the depth of drilling required, the depth to water, the yield, and the quality of the water, together with other information on drilling conditions and developing. Springs are a significant so

The present study aimed to gather relevant information and investigate social determinants of dietary compliance. A telephone survey was carried out on a representative population sample. Quotas were applied for gender, geography and degree of urbanisation. Individuals were eligible if they were hypercholesterolaemic, and were being followed by a doctor. Sociodemographic, socioeconomic and health data were collected, as well as information about the individuals' perception of the disease, their relationship and beliefs surrounding food, and their food behaviour (shopping, cooking, eating-out, deviation from prescribed diet). The association between compliance with diet and medication was investigated. Overall, 802 individuals were included, representing 8% of those contacted, as opposed to the expected 20%. Mean (SD) age was 60 (14.2) years, with 51% of individuals living as a couple; 48% had a good level of physical activity; 44% considered that the hypercholesterolaemia was inherited; 31% felt that the disease was normal beyond the age of 45 years. The functional and convivial aspects of eating were of more importance than that of health maintenance. Cheese was particularly likely to be eaten in dietary lapses. Of a subgroup of 729 individuals, 476 (65%) took medication; of these 476 individuals, 51% complied with dietary recommendations (P < 0.05). The key factors associated with dietary compliance in hypercholesterolaemic individuals were identified: age, sex, the perceptions of hypercholesterolaemia, and the sociocultural aspects of food. By contrast to general assumptions, both dietary and medicinal measures are practised fairly well by a large proportion of these individuals. © 2011 The Authors.

    Recent research by the U.S. Geological Survey has characterized contaminant sources and identified important geochemical processes that influence transport of radionuclides from uranium mining and milling wastes. 1) Selective extraction studies indicated that alkaline earth sulfates and hydrous ferric oxides are important hosts of 226Ra in uranium mill tailings. The action of sulfate-reducing and ironreducing bacteria on these phases was shown to enhance release of radium, and this adverse result may temper decisions to dispose of uranium mill tailings in anaerobic environments. 2) Field studies have shown that although surface-applied sewage sludge/wood chip amendments aid in revegetating pyritic spoil, the nitrogen in sludge leachate can enhance pyrite oxidation, acidification of groundwater, and the consequent mobilization of metals and radionuclides. 3) In a U.S. Environmental Protection Agencyfunded study, three permeable reactive barriers consisting of phosphate-rich material, zero-valent iron, or amorphous ferric oxyhydroxide have been installed at an abandoned uranium upgrader facility near Fry Canyon, UT. Preliminary results indicate that each of the permeable reactive barriers is removing the majority of the uranium from the groundwater. 4) Studies on the geochemistry of rare earth elements as analogues for actinides such as uranium and thorium in acid mine drainage environments indicate high mobility under acid-weathering conditions but measurable attenuation associated with iron and aluminum colloid formation. Mass balances from field and laboratory studies are being used to quantify the amount of attenuation. 5) A field study in Colorado demonstrated the use of 234U/238U isotopic ratio measurements to evaluate contamination of shallow groundwater with uranium mill effluent.

    Full Text Available Background Formulation of herbs into dosage forms promotes their marketing and usage. However, if these herbal products are being taken in an unhealthy trend, they may pose risks to consumers. Aims The present study aimed to investigate herbal product consumption trends (n=550 among adults in the main cities of Malaysia. Methods A questionnaire-based, six-week cross-sectional study was conducted. Respondents were randomly selected in Shah Alam, Klang, Subang, and Kuala Lumpur. Descriptive statistics were used for data analysis and Chi-square test was applied where appropriate. Results Out of the 550 survey instruments distributed, 453(82.4 per cent responded. The prevalence rate of herbal products use among the adult population in the past 12 months was 71.5 per cent. Regarding the consumption profile; the consumers were mostly female (73.4 per cent, age 25–44 (72.8, and educated at tertiary level (74.8 per cent. The majority of respondents perceived that herbal products helped reduce severity of illness and improve health related quality of life, while (16.4 per cent consumed the herbal products for the treatment of menstrual problem, 71.7 per cent without the recommendation of health care professionals and 85.0 per cent of them purchased through over-the-counter retail sales. The herbal products most commonly consume were Labisia pumila (Kacip Fatimah (32.4 per cent, Camellia sinensis (Green Tea (32.1 per cent, Panax ginseng (Ginseng (23.8 per cent, and Eurycoma longifolia (Tongkat Ali (22.5 per cent. Conclusion This study highlights an unhealthy trend in self-prescription of herbal product consumption without healthcare professionals’ recommendation. Hence, there is an urgent need for healthcare professionals to monitor herbal product consumption.

    We adapt the classical Q-method based on a reddening-free parameter constructed from three passband magnitudes to the filter set of Isaac Newton Telescope Photometric Hα Survey and combine it with the maximum-likelihood-based cluster parameter estimator by Naylor & Jeffries (2006) to determine the extinction, heliocentric distances, and ages of young open clusters using Hαri data. The method is also adapted for the case of significant variations of extinction across the cluster field. Our technique is validated by comparing the colour excesses, distances, and ages determined in this study with the most bona fide values reported for the 18 well-studied young open clusters in the past and a fairly good agreement is found between our extinction and distance estimates and earlier published results, although our age estimates are not very consistent with those published by other authors. We also show that individual extinction values can be determined rather accurately for stars with (r - i) > 0.1. Our results open up a prospect for determining a uniform set of parameters for northern clusters based on homogeneous photometric data, and for searching for new, hitherto undiscovered open clusters.

  10. Variation in Direct Access to Tests to Investigate Cancer: A Survey of English General Practitioners.

    Directory of Open Access Journals (Sweden)

    Brian D Nicholson

    Full Text Available The 2015 NICE guidelines for suspected cancer recommend that English General Practitioners have direct access to diagnostic tests to investigate symptoms of cancer that do not meet the criteria for urgent referral. We aimed to identify the proportion of GPs in England with direct access to these tests.We recruited 533 English GPs through a national clinical research network to complete an online survey about direct access to laboratory, radiology, and endoscopy tests in the three months leading up to the release of the 2015 NICE guidance. If they had direct access to a diagnostic test, GPs were asked about the time necessary to arrange a test and receive a report. Results are reported by NHS sub-region and, adjusting for sampling, for England as a whole.Almost all GPs reported direct access to x-ray and laboratory investigations except faecal occult blood testing (54%, 95% CI 49-59% and urine protein electrophoresis (89%, 95% CI 84-92%. Fewer GPs had direct access to CT scans (54%, 95% CI 49-59% or endoscopy (colonoscopy 32%, 95% CI 28-37%; gastroscopy 72%, 95% CI 67-77%. There was significant variation in direct access between NHS regions for the majority of imaging tests-for example, from 20 to 85% to MRI. Apart from x-ray, very few GPs (1-22% could access radiology and endoscopy within the timescales recommended by NICE. The modal request to test time was 2-4 weeks for routine radiology and 4-6 weeks for routine endoscopy with results taking another 1-2 weeks.At the time that the 2015 NICE guideline was released, local investment was required to not only provide direct access but also reduce the interval between request and test and speed up reporting. Further research using our data as a benchmark is now required to identify whether local improvements in direct access have been achieved in response to the NICE targets. If alternative approaches to test access are to be proposed they must be piloted comprehensively and underpinned by robust

    Study explanatory forms often state that an ethics committee has approved a research project. To determine whether the lay community understand the roles of ethics committees in research, we took a cross-sectional national sample from three sampling frames: the general population (n=1532); cohort study participants (n=397); and case-control study participants (n=151). About half (51.3%) of the participants had heard of ethics committees. Those who had were more likely to be those who had participated in previous surveys, older participants, those born in Australia and those with higher education. Almost all participants agreed that the roles of an ethics committee were to protect participants' privacy and ensure no harm came to study participants and most agreed that the committee's role was to ensure that the research was capable of providing answers. Case-control and cohort participants were more likely than the general population to consider that the role of an ethics committee was to design the research and obtain research funding. Overall, we found that about half of the population are aware of ethics committees and that most could correctly identify that ethics committees are there to protect the welfare and rights of research participants, although a substantial minority had some incorrect beliefs about the committees' roles. Increased education, particularly for migrants and older people, might improve understanding of the role of ethics committees in research. Published by the BMJ Publishing Group Limited.

    1978-09-01

    The objective of the vegetation studies conducted on the research site is to produce a descriptive data base that can be applied to determinations of carrying capacity of the site and surrounding area. Additional information obtained about parameters that influence vegetation growth and maintenance of soil nutrients, and moisture and temperature regimes help define dynamic relationships that must be understood to effect successful revegetation and habitat rehabilitation. The descriptive vegetation baseline also provides a point of departure for design of future monitoring programs, and predictive models and strategies to be used in dealing with impact mitigation; in turn, monitoring programs and predictive modeling form the bases for making distinctions between natural trends and man-induced perturbations.

    OBJECTIVE To determine whether associations existed between onychectomy or onychectomy technique and house soiling in cats. DESIGN Cross-sectional study. SAMPLE 281 owners of 455 cats in Polk County, Iowa, identified via a list of randomly selected residential phone numbers of cat owners in that region. PROCEDURES A telephone survey was conducted to collect information from cat owners on factors hypothesized a priori to be associated with house soiling, including cat sex, reproductive status, medical history, and onychectomy history. When cats that had undergone onychectomy were identified, data were collected regarding the cat's age at the time of the procedure and whether a carbon dioxide laser (CDL) had been used. Information on history of house soiling behavior (urinating or defecating outside the litter box) was also collected. RESULTS Onychectomy technique was identified as a risk factor for house soiling. Cats for which a non-CDL technique was used had a higher risk of house soiling than cats for which the CDL technique was used. Cats that had undergone onychectomy and that lived in a multicat (3 to 5 cats) household were more than 3 times as likely to have house soiled as were single-housed cats with intact claws. CONCLUSIONS AND CLINICAL RELEVANCE Results of this cross-sectional study suggested that use of the CDL technique for onychectomy could decrease the risk of house soiling by cats relative to the risk associated with other techniques. This and other findings can be used to inform the decisions of owners and veterinarians when considering elective onychectomy for cats.

    The workload affects the quality of the pathology report. The aim of this study was to investigate the territorial distribution and productivity of pathology laboratories around Turkey and to estimate the staff workload. A survey questioning the workload was sent to all Ministry of Health and university hospitals. Staff workload was questioned according to the hospital classification and educational activity to evaluate the productivity. Data were entered using SPSS 16.0 statistical software package program and the distribution criteria, t-test and one-way anova were used in the analysis to evaluate the differences between the averages. An average of 2.8 pathologists worked at the pathology laboratories. A total of 5.500 biopsies and 3.750 cytology specimens were received and 20.000 blocks prepared per year. Pathologists evaluated 1.935 biopsies and 1.400 cytology specimens on average and this is equivalent to 2.718 biopsies per year. Gynecology and general surgery department materials constituted 57 percent of all biopsies. Each technician prepared 6.200 blocks, 11.500 slides and 1.000 immunohistochemistry preparations on average. An average of 3.4 paraffin blocks was prepared for each biopsy. The efficiency was low in 17% of teaching hospitals and 77.8% of non-teaching hospitals. In contrast 62.5% of teaching hospitals had work overload. The majority (70.5%) of the respondents mentioned staff shortage. There is no pathologist shortage in Turkey and the problem is workload distribution. Pathology residents' overwork would be reduced by using pathology assistants. There is no shortage of technicians or secretaries, but uneven distribution. Pathology staff planning must be tailored taking into account the features of each hospital. Standard planning for all hospitals is not suitable.

    Kapsetaki, Marianna Evangelia; Easmon, Charlie

    2017-07-14

    This study aimed to estimate the prevalence of eating disorders (EDs) in musicians, and to evaluate their relation to perfectionism, stress, anxiety and depression. It examined: (1) the prevalence of EDs using the Eating Disorder Examination Questionnaire (EDE-Q), body mass index (BMI) and self-reports, (2) psychological risk factors using the Depression Anxiety Stress Scale (DASS-21) and perfectionism inventory and (3) demographic details, information about musical and career development, lifestyle, eating habits and health. A survey was distributed worldwide and a total of 301 English-speaking musicians aged 18 years and older participated. Our screening tools for EDs showed a high prevalence of EDs in musicians: the EDE-Q Global Score (EDE-QGS) showed pathological values in 18.66% of the musicians and when questioned about lifetime prevalence, 32.3% of the musicians answered positively. The median BMI was within the normal range. Regarding general mental health, the DASS-21 showed that depression and stress were severe, anxiety was extremely severe and the perfectionism inventory composite score was 26.53. There was no significant difference on the EDE-QGS between musicians who perform different types of music, but music students, professionals, soloists and musicians travelling overseas had a higher percentage of pathological EDE-QGS. Perfectionism was higher in classical musicians and there was a low positive correlation between EDE-QGS and the risk factors: perfectionism, depression, anxiety, stress, peer pressure and social isolation. EDs are prevalent in musicians and possible risk factors are their increased perfectionism, depression, anxiety and stress due to the demands of their job.

    For the purpose of commercializing the coal gasification fuel cell combined cycle power system, survey/study on the production technology of fuel cell use coal gas were conducted, and the FY 1999 results were reported. The survey in the U.S. indicated that all of three IGCC plants in the U.S. had experienced troubles in the early stage and had now been in somewhat stable operation by taking measures therefor. Survey was also made of the state of progress of IGCC plants now in operation/trial operation in Europe. Further, survey was conducted of the Carina cycle, high efficiency cycle with a water-ammonia mixture as medium. As to the element test in this fiscal year, the test using gasifier was conducted for Adaro coal (high water content coal produced in Indonesia), one of the coals to be used for pilot plant. As a result, the following information/knowledge were obtained: the equilibrium value of the shift reaction was fixed, about 0.6, regardless of the oxygen ratio; the initial reaction rate of char gasification in CO2 was almost fixed, regardless of the carbon concentration in char.

    Few studies or investigators involved in community-engaged research or community-based participatory research have examined awareness and adoption of federal regulatory mechanisms. We conducted a survey of investigators affiliated with the 10 National Institutes of Health (NIH) Centers for Population Health and Health Disparities. A questionnaire designed to capture experience with the conduct and oversight of community-engaged research, and awareness of pertinent regulatory mechanisms, including Federalwide Assurances (FWAs), Individual Investigator Agreements (IIAs), and Institutional Review Board Authorization Agreements (IAAs), was completed by 101 respondents (68% response rate). Although most were aware of FWAs, only a minority of those surveyed reported knowledge of IAAs and IIAs and even fewer had used them in their research with community partners. Implications for future training and oversight are discussed. © The Author(s) 2014.

    2017-11-01

    This study examined shame and responses to it in adult dissociative disorder (DD; n = 24) and comparison psychiatric (n = 14) samples. To investigate how helpful different therapeutic responses are after shame disclosures in therapy, participants heard two vignettes from "mock" patients disclosing a) shame and b) surprise. Participants rated the helpfulness of five potential responses. Interventions covered withdrawing from the affect (withdrawal focused) to feeling it (feeling focused), with other interventions on cognitions (cognitive focused), management strategies (management focused), and previous experiences (history focused). The DD sample reported higher characterological and bodily shame, and more shame avoidance and withdrawal. There was no difference across groups for intervention ratings. For shame, interventions focused on feelings, cognitions, or previous shame experiences were deemed most helpful, but this was qualified by experiencing dissociation while hearing the script, where the history intervention was reported less helpful. Exposure to shame while monitoring dissociation should accompany therapy for DDs.

  12. DNA typing in forensic medicine and in criminal investigations: a current survey

    Science.gov (United States)

    Benecke, Mark

    Since 1985 DNA typing of biological material has become one of the most powerful tools for personal identification in forensic medicine and in criminal investigations [1-6]. Classical DNA "fingerprinting" is increasingly being replaced by polymerase chain reaction (PCR) based technology which detects very short polymorphic stretches of DNA [7-15]. DNA loci which forensic scientists study do not code for proteins, and they are spread over the whole genome [16, 17]. These loci are neutral, and few provide any information about individuals except for their identity. Minute amounts of biological material are sufficient for DNA typing. Many European countries are beginning to establish databases to store DNA profiles of crime scenes and known offenders. A brief overview is given of past and present DNA typing and the establishment of forensic DNA databases in Europe.

    Although the shortened dental arch (SDA) concept has been known to all over the world, acceptance of the SDA concept as an oral health standard can be questionable from the patients' point of view, even if it is biologically reasonable. Furthermore, because the health insurance system covers removable partial dentures (RPDs) for all citizens in Japan, SDA patients seem to prefer to receive prosthetic treatment to replace the missing teeth. However, there were few field surveys to investigate the usage rate of RPDs in Japan. The purpose of this study was to determine the usage rate of RPDs in older Japanese subjects and to investigate the factors related to the usage of RPDs. Partially edentate participants (n = 390) were included in this study. Oral examinations were conducted to record several indices. The Cochran-Armitage trend test was used to evaluate the relationship between the number of missing teeth and the usage rate of RPDs. Chi-squared tests and logistic regression analysis were conducted to evaluate the factors related to the usage rate of RPDs. Usage of RPDs had a significantly positive association with the number of missing distal extension teeth and bilaterally missing teeth. The usage rate of RPDs increased as the number of missing distal extension teeth increased (P for trend < 0·001). The conclusion of this study was that participants with missing distal extension teeth had higher usage rates of RPDs than other participants, and the usage rate increased as the number of missing distal extension teeth increased. © 2015 John Wiley & Sons Ltd.

    The aims of this descriptive cross-sectional study were to investigate dog and cat acquisition and attitudes toward pet care among residents of the Chicago area (zip codes 60600-60660); to compare data obtained from owners of shelter-acquired pets with those of residents who acquired their pets from other sources; to compare data from dog owners with cat owners; and to compare pet health practices among the respondents of different zip code income groups. In-person surveys administered at five pet store locations collected data from 529 respondents, representing 582 dogs and 402 cats owned or continuously cared for in the past 3 years. Median household income data for represented zip codes was also obtained. Shelters were the most common source of cats (ppet stores, breeders or rescue organizations and to be kept as outdoor-only pets (pPet owners were most commonly 'very likely' (5 on a 1-5/5 Likert scale) to administer all hypothetical treatments discussed, although cat owners were less likely to spend time training their pet (p=0.05). Cat owners were less likely to have taken their pet to a veterinarian for vaccinations or annual physical exams (ppets were at least as willing as other respondents to administer hypothetical treatments and pay ≥$1000 for veterinary treatment. Respondents from site #3 lived in zip codes that had relatively lower median household incomes (ppets than those at the four other sites (ppet owners from all acquisition categories expressed very high levels of attachment (≥8-10/10 on a Likert scale), except for owners of cats acquired as strays (84.9%) or from the 'other' category (75.0%). Survey respondents commonly acquired their pets from shelters and those who did were at least as willing to pay for and provide veterinary care as respondents who owned pets acquired from other sources. The data collected provides a snapshot of the attitudes of survey respondents in the Chicago area toward pet acquisition and care. Copyright © 2014

    Near surface geophysics applications are gaining more widespread use in geotechnical and engineering projects. The development of data acquisition, processing tools and interpretation methods have optimized survey time, reduced logistics costs and increase results reliability of seismic surveys during the last decades. However, the use of wide-scale geophysical methods under urban environments continues to face great challenges due to multiple noise sources and obstacles inherent to cities. A seismic pre-investigation was conducted to investigate the feasibility of using seismic methods to obtain information about the subsurface layer locations and media properties in Copenhagen. Such information is needed for hydrological, geotechnical and groundwater modeling related to the Cityringen underground metro project. The pre-investigation objectives were to validate methods in an urban environment and optimize field survey procedures, processing and interpretation methods in urban settings in the event of further seismic investigations. The geological setting at the survey site is characterized by several interlaced layers of clay, till and sand. These layers are found unevenly distributed throughout the city and present varying thickness, overlaying several different unit types of limestone at shallow depths. Specific results objectives were to map the bedrock surface, ascertain a structural geological framework and investigate bedrock media properties relevant to the construction design. The seismic test consisted of a combined seismic reflection and refraction analyses of a profile line conducted along an approximately 1400 m section in the northern part of Copenhagen, along the projected metro city line. The data acquisition was carried out using a 192 channels array, receiver groups with 5 m spacing and a Vibroseis as a source at 10 m spacing. Complementarily, six vertical seismic profiles (VSP) were performed at boreholes located along the line. The reflection

    Greater attention is currently being paid to the relationship between indoor environment and childhood allergies, however, the lack of reliable data and the disparity among different areas hinders reliable assessment of the relationship. This study focuses on the effect of indoor pollution on Chinese schoolchildren and the relationship between specific household and health problems suffered. The epidemiological questionnaire survey and the field measurement of the indoor thermal environment and primary air pollutants including CO₂, fine particulate matter (PM 2.5 ), chemical pollutants and fungi were performed in six Chinese cities. A total of 912 questionnaires were eligible for statistical analyses and sixty houses with schoolchildren aged 9-12 were selected for field investigation. Compared with Chinese national standards, inappropriate indoor relative humidity (70%), CO₂ concentration exceeding 1000 ppm and high PM 2.5 levels were found in some monitored houses. Di(2-ethylhexyl) phthalate (DEHP) and dibutyl phthalate (DBP) were the most frequently detected semi-volatile organic compounds (SVOCs) in house dust. Cladosporium , Aspergillus and Penicillium were detected in both indoor air and house dust. This study indicates that a thermal environment with CO₂ exceeding 1000 ppm, DEHP and DBP exceeding 1000 μg/g, and high level of PM 2.5 , Cladosporium , Aspergillus and Penicillium increases the risk of children's allergies.

    Full Text Available Landslide is one of prominent geohazards that frequently affects Indonesia, especially in the rainy season. It destroys not only environment and property, but usually also causes deaths. Landslide monitoring is therefore very crucial and should be continuously done. One of the methods that can have a contribution in studying landslide phenomena is repeated GPS survey method. This paper presents and discusses the operational performances, constraints and results of GPS surveys conducted in a well known landslide prone area in West Java (Indonesia, namely Megamendung, the hilly region close to Bogor. Three GPS surveys involving 8 GPS points have been conducted, namely on April 2002, May 2003 and May 2004, respectively. The estimated landslide displacements in the area are relatively quite large in the level of a few dm to a few m. Displacements up to about 2-3 m were detected in the April 2002 to May 2003 period, and up to about 3-4 dm in the May 2003 to May 2004 period. In both periods, landslides in general show the northwest direction of displacements. Displacements vary both spatially and temporally. This study also suggested that in order to conclude the existence of real and significant displacements of GPS points, the GPS estimated displacements should be subjected to three types of testing namely: the congruency test on spatial displacements, testing on the agreement between the horizontal distance changes with the predicted direction of landslide displacement, and testing on the consistency of displacement directions on two consecutive periods.

    For the purpose of commercializing the coal gasification fuel cell combined cycle power system, survey/study on the production technology of fuel cell use coal gas were conducted, and the FY 2000 results were reported. As to the coal gasification technology in countries of the world, survey was made of the state of the operation in IGCC projects in Indiana State and Florida State in the U.S. and the IGCC project in Spain. Survey was also made of the gas turbine cycle using humid air, HAT (humid air turbine). In the element study, the gasification test using the pressurized gasification test furnace was conducted for Bontang coal (bituminous coal produced in Indonesia), one of the coals to be used for pilot plant. As a result, the following information/knowledge were obtained: the value of shift reaction was 0.6 or so, less affected by the kind of coal and oxygen ratio; the reaction rate of char gasification in CO2 was high in order of Bontang coal, White Oak coal and Adaro coal. Further, the analysis of the pressurized gasification test furnace was carried out using the simulator for the entrained bed coal gasification. (NEDO)

    There is an international emphasis on providing timely and high quality data to monitor progress of countries toward Millennium Development Goals. Iran's Multiple Indicator Demographic and Health Survey (IrMIDHS) aimed to provide valid information on population and health outcomes to monitor progress in achieving national priorities and health programs and to assist policy makers to design effective strategies for improving health outcomes and equity in access to care. A cross-sectional multi-stage stratified cluster-random survey is conducted through face-to-face household interviews. The sampling frame is developed using Iran's 2006 population and housing census. Provincial samples ranging are from a minimum of 400 households per province to 6400 households in Tehran province. Cluster size is 10 households. The target sample includes 3096 clusters: 2187 clusters in urban and 909 clusters in rural areas. IrMIDHS instruments include three questionnaires: Household questionnaire, women aged 15-54 questionnaire, children under five questionnaire, supervision and quality assessment checklists and data collection sheets and standard weight and height measurement tools for under-five children. A cascading decentralized training method is used for training data collection and supervision teams. Quality assurance procedures are defined for the five steps of conducting the survey including: Sampling, training data collection and training teams, survey implementation, data entry and analysis. A multi-layer supervision and monitoring procedure is established. All the questionnaires are double entered. IrMIDHS will provide valuable data for policymakers in Iran. Designing and implementation of the study involve contributions from academics as well as program managers and policy makers. The collaborative nature of the study may facilitate better usage of its results.

  5. Investigations in the Spectral Properties of Operators with Distant Perturbations (survey

    2015-01-01

    Full Text Available We propose a chronological overview of researches on operators with distant perturbations. Let us explain what "distant perturbations" mean. An elementary example of the operator with distant perturbations is a differential operator of the second order with two finite potentials. Supports of these operators are at a great distance from each other, i.e. they are \\distant".The study of such operators has been performed since the middle of the last century, mostly by foreign researchers see eg. R. Ahlrichs, T. Aktosun, M. Klaus, P. Aventini, P. Exner, E.B. Davies, V. Graffi, E.V. Harrell II, H.J. Silverstone, M. Mebkhout, R. Hoegh-Krohn, W. Hun ziker, V. Kostrykin, R. Schrader, J.D. Morgan (III, Y. Pinchover, O.K. Reity, H. Tamura, X. Wang, Y. Wang, S. Kondej, B. Simon, I. Veselic, D.I. Borisov, A.M. Golovina. The main objects of their investigation were the asymptotic behaviors of eigenvalues and corresponding eigenfunctions of perturbed operators. In several papers the research was focused on resolvents and eigenvalues of perturbed operator arising from the edge of the essential spectrum. The main results of the past century are the first members of the asymptotics of perturbed eigenvalues and the corresponding eigenfunctions and the first members of the asymptotics of resolvents of the perturbed operators. The main results of the last fifteen years are full asymptotic expansions for the eigenvalues and their corresponding functions and an explicit formula for the resolvent of the perturbed operator.In this paper, we also note that up to 2004 only different kind of potentials were considered as perturbing operators, and Laplace and Dirac operators were considered as unperturbed operators. Only since 2004, nonpotential perturbing operators appeared in the literature. Since 2012, an arbitrary elliptic differential operator is considered as an unperturbed operator.We propose a classification of investigations on distant perturbations, based on the

    Masters, Daniel Charles

    Large multiwavelength surveys are now driving the frontiers of astronomical research. I describe results from my work using data from two large astronomical surveys: the Cosmic Evolution Survey (COSMOS), which has obtained deep photometric and spectroscopic data on two square degrees of the sky using many of the most powerful telescopes in the world, and the WFC3 Infrared Spectroscopic Parallels (WISP) Survey, which uses the highly sensitive slitless spectroscopic capability of the Hubble Space Telescope Wide Field Camera 3 to detect star-forming galaxies over most of the universe's history. First I describe my work on the evolution of the high-redshift quasar luminosity function, an important observational quantity constraining the growth of the supermassive black holes in the early universe. I show that the number density of faint quasars declines rapidly above z ˜ 3. This result is discussed in the context of cosmic reionization and the coevolution of galaxies and their central black holes. Next I present results of a multi-year campaign of near-infrared spectroscopy with FIRE, a world-class near-infrared spectrometer on the Magellan Baade 6.5 meter telescope in Chile, targeting emission-line galaxies at z ˜ 2 discovered with the Hubble Space Telescope. Our results showed that the typical emission-line galaxy at this redshift has low-metallicity, low dust obscuration, high ionization parameter, and little evidence for significant active galactic nucleus (AGN) contribution to the emission lines. We also find evidence that high redshift star-forming galaxies have enhanced nitrogen abundances. This result has interesting implications for the nature of the star formation in such galaxies -- in particular, it could mean that a large fraction of such galaxies harbor substantial populations of Wolf-Rayet stars, which are massive, evolved stars ejecting large amounts of enriched matter into the interstellar medium. Finally, I will discuss the discovery of three

    The number of medical studies performed through online surveys has increased dramatically in recent years. Despite their numerous advantages (eg, sample size, facilitated access to individuals presenting stigmatizing issues), selection bias may exist in online surveys. However, evidence on the representativeness of self-selected samples in online studies is patchy. Our objective was to explore the representativeness of a self-selected sample of online gamers using online players' virtual characters (avatars). All avatars belonged to individuals playing World of Warcraft (WoW), currently the most widely used online game. Avatars' characteristics were defined using various games' scores, reported on the WoW's official website, and two self-selected samples from previous studies were compared with a randomly selected sample of avatars. We used scores linked to 1240 avatars (762 from the self-selected samples and 478 from the random sample). The two self-selected samples of avatars had higher scores on most of the assessed variables (except for guild membership and exploration). Furthermore, some guilds were overrepresented in the self-selected samples. Our results suggest that more proficient players or players more involved in the game may be more likely to participate in online surveys. Caution is needed in the interpretation of studies based on online surveys that used a self-selection recruitment procedure. Epidemiological evidence on the reduced representativeness of sample of online surveys is warranted.

    The 2015 National Mental Health Survey (NMHS) is the fourth mental survey conducted in Colombia, and is part of the National System of Surveys and Population Studies for health. A narrative description is used to explain the background, references, the preparation, and characteristics of the 2015 NMHS. The 2015 NMHS and its protocol emerge from the requirements that support the national and international policies related to mental health. Together with the Ministry of Health and Social Protection, the objectives, the collection tools, the sample, and the operational plan are defined. The main objective was to obtain updated information about the mental health, mental problems and disorders, accessibility to health services, and an evaluation of health conditions. Participants were inhabitants from both urban and rural areas, over 7 years old, and in whom the comprehension of social determinants and equity were privileged. An observational cross-sectional design with national, regional and age group representativity, was used. The age groups selected were 7-11, 12-17, and over 18 years old. The regions considered were Central, Orient, Atlantic, Pacific, and Bogota. The calculated sample had a minimum of 12,080 and a maximum of 14,496 participants. A brief summary of the protocol of the 2015 NMHS is presented. The full document with all the collection tools can be consulted on the Health Ministry webpage. Copyright © 2016.

    The paper studied a system to effectively use unused and low-grade thermal energy (cold heat and hot heat) in the Tokyo-Yokohama seaside area. For transportation of thermal energy, the batch transportation, that is, off-line system was discussed which uses insulated tank loaded barges and railroad freight trains. Thermal energy supply sources are 1) 0.3 million kW class thermal power plant, and 2) LNG storage base of 3 million ton/year class. Thermal energy users are Tokyo (Haneda) Airport D.H.C. (District Heating/Cooling Co.), MM 21 D.H.C. and Shin-Kawasaki D.H.C. The cold heat energy supplied to these three is about 1.5 million Mcal/daytimes300 days/year, and the hot heat energy supplied is about 1.33 million Mcal/daytimes150 days/year. Cold heat is obtained from seawater after the LNG vaporization, and hot heat from heat extracted from thermal turbine. Subcooled ice was selected for cold heat medium, and PCM-120A for hot heat medium. For batch transportation, an STL heat storage system is used which transports plastic capsules sealed with heat medium. Oil saving of 62,000 tons/year and CO2 reduction of about 53,000 tons/year can be expected. 85 figs., 98 tabs.

    For the purpose of commercializing the coal gasification fuel cell combined cycle power system, survey/study on the production technology of fuel cell use coal gas were conducted, and the FY 1998 results were reported. In the survey in the U.S., information/knowledge on the state of the progress of the coal gasification combined cycle power generation project were obtained through the participation in the gasification conference and the coal science conference held by EPRI. Survey was also made on the positioning of coal in the power generation field in Japan. The pilot plant for coal gasifier and gas refining facilities is now under construction. In this fiscal year, for evaluation of the kind of coal to be used for this plant, the gasification test using small pressurized gasifier was made for white oak coal. As a result, the equilibrium value of shift reaction was about 0.6, and equilibrium temperature was about 1,050 degrees C, which were fixed regardless of the oxygen ratio. The initial reaction rate of char gasification in H{sub 2}O was about 1.8 times as high as that in CO2, but the activation energy was the same, about 93.5 kJ/mol. (NEDO)

    During the last decade, DNA profiling and the use of DNA databases have become two of the most employed instruments of police investigations. This very rapid establishment of forensic genetics is yet far from being complete. In the last few years novel types of analyses have been presented to describe phenotypically a possible perpetrator. We conducted the present study among German speaking Swiss residents for two main reasons: firstly, we aimed at getting an impression of the public awareness and acceptance of the Swiss DNA database and the perception of a hypothetical DNA database containing all Swiss residents. Secondly, we wanted to get a broader picture of how people that are not working in the field of forensic genetics think about legal permission to establish phenotypic descriptions of alleged criminals by genetic means. Even though a significant number of study participants did not even know about the existence of the Swiss DNA database, its acceptance appears to be very high. Generally our results suggest that the current forensic use of DNA profiling is considered highly trustworthy. However, the acceptance of a hypothetical universal database would be only as low as about 30% among the 284 respondents to our study, mostly because people are concerned about the security of their genetic data, their privacy or a possible risk of abuse of such a database. Concerning the genetic analysis of externally visible characteristics and biogeographical ancestry, we discover a high degree of acceptance. The acceptance decreases slightly when precise characteristics are presented to the participants in detail. About half of the respondents would be in favor of the moderate use of physical traits analyses only for serious crimes threatening life, health or sexual integrity. The possible risk of discrimination and reinforcement of racism, as discussed by scholars from anthropology, bioethics, law, philosophy and sociology, is mentioned less frequently by the study

    Measures from the Social Context Module of the Centers for Disease Control and Prevention's Behavioral Risk Factor Surveillance System were used on 2 population-based health surveys in Hawaii to explicate the role of the nonmedical and social determinants of health; these measures were also compared with conventional socioeconomic status (SES) variables. Results showed that the self-reported SES vulnerabilities of food and housing insecurity are both linked to demographic factors and physical and mental health status and significant when controlling for the conventional measures of SES. The social context module indicators should be increasingly used so results can inform appropriate interventions for vulnerable populations.

    To evaluate non-response rates to follow-up online surveys using a prospective cohort of parents raising at least one child with an autism spectrum disorder. A secondary objective was to investigate predictors of non-response over time. Data were collected from a US-based online research database, the Interactive Autism Network (IAN). A total of 19,497 youths, aged 1.9-19 years (mean 9 years, SD 3.94), were included in the present study. Response to three follow-up surveys, solicited from parents after baseline enrollment, served as the outcome measures. Multivariate binary logistic regression models were then used to examine predictors of non-response. 31,216 survey instances were examined, of which 8772 or 28.1% were partly or completely responded to. Results from the multivariate model found non-response of baseline surveys (OR 28.0), years since enrollment in the online protocol (OR 2.06), and numerous sociodemographic characteristics were associated with non-response to follow-up surveys (all p<0.05). Consistent with the current literature, response rates to online surveys were somewhat low. While many demographic characteristics were associated with non-response, time since registration and participation at baseline played the greatest role in predicting follow-up survey non-response. An important hazard to the generalizability of findings from research is non-response bias; however, little is known about this problem in longitudinal internet-mediated research (IMR). This study sheds new light on important predictors of longitudinal response rates that should be considered before launching a prospective IMR study.

    This study analyzed the forensic features of homicides in North-West Greece (Epirus) from 1998 to 2013, a borderland area between Greece and Albania. Although Greece is critically influenced by both the increasing flow of refugees and the current socioeconomic crisis, very little information has been published regarding the patterns of homicide in the country. Fifty-eight autopsied victims (36 males; 22 females) were investigated. The median age was 37 years old. The average annual homicide rate was 0.85 per 100,000 inhabitants and showed remarkable fluctuation, with largest increase during Greek financial downturn. Sixteen victims were not Greek citizens. The most common method of commitment was the use of firearm (40%). The main motives were economical causes (26%) and passion (14%). Four cases were categorized as matricide (7%), 3 as homicide-suicide (5%), 2 as patricide (3%) and 1 as infanticide (2%). Toxicological analysis proved negative for ethanol and other psychotropic substances in the majority of the victims (50%). There is an urgent need for public actions both in Epirus and in Greece, with the application of effective strategies against criminality.

Two of the Fabry disease patients who completed the online survey were diagnosed with PD (2/90, 2.2%. Among probands older than 60, 8.3% (2/24 were diagnosed with PD. Using Kaplan Meier survival analysis, the age-specific risk of PD by age 70 was 11.1%. Family history was available on 72 Fabry families from the online study and 9 Fabry families from ISMMS. Among these 81 families, 6 (7.4% had one first degree relative who fit the criteria for a conservative diagnosis of PD. The results of this study suggest that there may be an increased risk of developing PD in individuals with GLA mutations, but these findings should be interpreted with caution given the limitations of the study design.

    Full Text Available In this paper we use the Aging and Social Support Survey (GSS16 and the theoretical conception of a ‘housing career’ to identify the correlates of housing tenure (rent vs. own among Canadians age 45 and over. We draw on primarily US literature to isolate three general explanatory clusters (social support, health, and economic characteristics. Based on analyses using logistic regression, the results indicate that the majority of variation in housing tenure exists due to standard demographic and household characteristics. In fact, of the three focal explanatory clusters, only social support characteristics significantly enhance model fit beyond the baseline model, suggesting that the housing tenure of older Canadians hinges heavily on fairly standard characteristics.

    To provide an opportunity for members to express their understandings of spirituality and spiritual care. The role and place of spirituality within nursing have been contested by academics and wider society. One argument posited is supporting patients with their spiritual needs is not the responsibility of nurses. This is despite a clear professional requirement for nurses to achieve competence in the delivery of spiritual care. The Royal College of Nursing (RCN) conducted an online survey of its membership to ascertain their perceptions of spirituality and spiritual care identifying current practice. This article presents the findings from the final part of the survey that asked respondents to use a free-text facility to add comments on the subjects of spirituality and spiritual care. Overall, 4054 RCN members responded, of these 2327 provided additional comments. These comments were analysed using keyword and content/thematic analysis. Five broad themes emerged: (1) theoretical and conceptual understanding of spirituality, (2) fundamental aspects of nursing, (3) notion of integration and integrated care, (4) education and professional development and (5) religious belief and professional practice. Findings suggest that nurses have diverse understandings of spirituality and the majority consider spirituality to be an integral and fundamental element of the nurses' role. Generally, nurses had a broad, inclusive understanding of spirituality considering this to be 'universal'. There was some uncertainty and fear surrounding the boundaries between personal belief and professional practice. Respondents advocated formal integration of spirituality within programmes of nurse education. The concept of spirituality and the provision of spiritual care are now recognised as fundamental aspects of the nurse's role. There is a need for greater clarity between personal and professional boundaries to enable nurses to feel more confident and competent in delivering spiritual

    Almost all research on sexual assault victimization among undergraduate university students pertains to incidents that occur on domestic college and university campuses. The purpose of the present study was to investigate the prevalence of sexual assault victimization and related factors among undergraduates in the context of study-abroad programs. Two hundred eight female students (52% response rate) from a small university in the northeastern United States who had recently studied abroad responded to an online survey containing measures of sexual assault, posttraumatic stress responses (PSR), and alcohol consumption. Almost 19% of the respondents indicated one or more types of sexual assault victimization. Approximately 17% reported non-consensual sexual touching, 7% attempted rape, 4% rape, with 9% reporting attempted rape or rape. As in domestic studies, victimization in this sample was related positively to alcohol consumption and PSR. Use of force was the most frequently reported perpetrator tactic. In sum, the high rates of sexual assault victimization reported by this sample during study abroad replicate previous findings. This context requires further attention from sexual assault researchers, especially given the increasing numbers of university students engaging in study abroad, and from campus support personnel who may be unaware of the likelihood of assault in this context. © The Author(s) 2014.

    Full Text Available Most scholars argue that cross-national research is indispensable for establishing the generalizability of theories and the validity of interpretations derived from single-nation studies. Another important aspect of comparative studies is that they force us to test our interpretations against cross-cultural diferences and inconsistencies. In journalism studies, the advantages of cross-national research are obvious. While the empirical inquiry into news-making has generated a vast quantity of data, some of the more fundamental questions in journalism research remain largely unresolved: What shapes the news and the structures of journalism most? Is it politics, economy, or culture? How do the conventional Western values of objective journalism ft in with non-Western cultures? In this article, I would like to propose the creation of a “World Journalism Survey”, modeled after the World Values Survey, for a better map of the cultural diferences in journalism practices around the world.

    As part of the Oxford Abdominal Aortic Aneurysm (OxAAA) Study, we conducted an international survey of vascular surgery professionals. One aspect of the survey is as published in the International Journal of Cardiology: "International Opinion on Priorities in Research for Small Abdominal Aortic Aneurysms and the Potential Path for Research to Impact Clinical Management". This Data-in-Brief article contains a detailed method for the conduct of this survey and additional original data. In this survey, we also provided vascular surgery colleagues with contemporary epidemiologic and surgical outcome data. This was followed by a hypothetical scenario whereby a patient had just been diagnosed with a small (40 mm) AAA and a novel biomarker predicted it to be fast growing in the coming years. We assessed the vascular professionals' perception of the patient's preference for management in this scenario, and their willingness to refer patients for a surgical trial that investigates the outcome of early versus late surgery in this setting. The survey then asked the vascular professionals to assume the role of the patient, and provided their own preferences in such a scenario.

There is little research that examines the advantages and disadvantages of different surveys in studies of nurse workforces. Previous studies that used different approaches to disseminate surveys. There are advantages and disadvantages to using postal or internet surveys for nurse workforce studies. Factors researchers may wish to consider in selecting survey methods include research topic, costs, coverage, timing and the characteristics of potential respondents. Response rate, data quality and adequate coverage of the population being studied can be optimised if the researcher selects an appropriate survey method.

    Patients with hypersomnia disorders (HD) suffer from debilitating symptoms that result in reduced functioning, depression, anxiety, and overall worse quality of life. Little is known about the need and desire of this population to utilize behavioral sleep medicine (BSM) interventions that focus on psychosocial functioning and quality of life, and there have been limited attempts to develop such interventions. The purpose of this survey study was to gather patient-centered data on engagement in pharmacological and nonpharmacological interventions, the psychosocial impact of HD symptoms on quality of life and mental health, and potential interest in BSM services, such as cognitive behavioral therapy, mindfulness or yoga, and support groups. We obtained responses from 371 individuals with HD (65.2% narcolepsy and 34.8% idiopathic hypersomnia) to an Internet-based survey. Overall, HD patients reported engagement in pharmacological and nonpharmacological interventions, with narcolepsy patients reporting more perceived effectiveness than those with idiopathic hypersomnia. In addition, HD patients reported a strong negative impact on psychosocial functioning, with elevations in depression and anxiety symptoms along with significant impact on functioning and quality of life. The majority (71.7-85.5%) voiced at least some interest in BSM services. These data suggest that there is substantial interest and need for BSM services that focus on assessment and treatment of psychosocial functioning related to HD.

    In its 2001 review of the U.S. Geological Survey (USGS), the National Research Council (NRC, p. 126) cautioned that ?high-quality personnel are essential for developing high-quality science information? and urged the USGS to ?devote substantial efforts to recruiting and retaining excellent staff.? Recognizing the importance of the NRC recommendation, the USGS has committed time and resources to create a rewarding work environment with the goal of achieving the following valued outcomes: ? USGS science vitality ? Customer satisfaction with USGS products and services ? Employee perceptions of the USGS as a rewarding place to work ? Heightened employee morale and commitment ? The ability to recruit and retain employees with critical skills To determine whether this investment of time and resources was proving to be successful, the USGS Human Resources Office conducted a Rewarding Environment Culture Study to answer the following four questions. ? Question 1: Does a rewarding work environment lead to the valued outcomes (identified above) that the USGS is seeking? ? Question 2: Which management, supervisory, and leadership behaviors contribute most to creating a rewarding work environment and to achieving the valued outcomes that the USGS is seeking? ? Question 3: Do USGS employees perceive that the USGS is a rewarding place to work? ? Question 4: What actions can and should be taken to enhance the USGS work environment? To begin the study, a conceptual model of a rewarding USGS environment was developed to test assumptions about a rewarding work environment. The Rewarding Environment model identifies the key components that are thought to contribute to a rewarding work environment and the valued outcomes that are thought to result from having a rewarding work environment. The 2002 Organizational Assessment Survey (OAS) was used as the primary data source for the study because it provided the most readily available data. Additional survey data were included as they

    The Aegean region, including both W. Turkey and Central Greece, is one of the world's most rapidly-deforming regions of continental crust and has a seismic rate is exceptional on a world scale. SW Turkey is one of the most rapidly extending regions in the world where the extension appears to have commenced in middle or late Miocene time. Paleomagnetic work in W Turkey and Aegean islands has revealed the horizontal rotation of some crustal blocks. In W Turkey clockwise rotation on Karaburun peninsula west of Izmir by 44° in the last few Ma is detected, and anticlockwise rotation of 37° for the Seferihisar region. The area of W Turkey and the Aegean islands has very strong geothermal gradient in the world scale. Sığacık Gulf is located on south of Karaburun Peninsula, and it is restricted by two important ridges as Karaburun and Seferihisar Ridges. Recent geological and geophysical studies suggested that this area is both E-W trending normal and NE-SW trending strike-slip faulting caused deformation. The Seferihisar earthquake series were occurred here during 17-20 October 2005. For investigation of geothermal potential and hot water outlets on the seafloor, shallow seismic and magnetic surveys are preferred, which were carried out onboard Dokuz Eylül-1 vessel belongs to Dokuz Eylül University, in 2011. Approximately 250km seismic reflection data was collected along 27 lines. During seismic method used Sparker system which has 1 channel and 12 hydrophone with 17 m long streamer, as a seismic source used SIG Seismic Marine ELC 80 (4 kV & 3.2 KV DC). Seismic data processing (band pass filter, bottom mute, top mute, true amplitude recovery, time migration) was made using Promax program in the Seismic Laboratory in the Institute of Marine Science and Technology. The basement topography map was prepared using Kingdom Suite program drawing seabed line on these sections. Sea floor topography changes between 30-120 m, and this increases towards Ikaria Basin

    Background Increasingly, social contact and knowledge of other people’s attitudes and behavior are mediated by online social media such as Facebook. The main research to which this recruitment study pertains investigates the influence of parents on adolescent alcohol consumption. Given the pervasiveness of online social media use, Facebook may be an effective means of recruitment and intervention delivery. Objective The objective of the study was to determine the efficacy of study recruitment via social networks versus paid advertising on Facebook. Methods We conducted a quasi-experimental sequential trial with response rate as the outcome, and estimates of cost-effectiveness. The target population was parents of 13-17 year old children attending high schools in the Hunter region of New South Wales, Australia. Recruitment occurred via: method (1) social recruitment using Facebook, email-based, social networks, and media coverage followed by method (2) Facebook advertising. Results Using a range of online and other social network approaches only: method (1) 74 parents were recruited to complete a survey over eight months, costing AUD58.70 per completed survey. After Facebook advertising: method (2) 204 parents completed the survey over four weeks, costing AUD5.94 per completed survey. Participants were representative of the parents recruited from the region’s schools using standard mail and email. Conclusions Facebook advertising is a cost-effective means of recruiting parents, a group difficult to reach by other methods. PMID:25230740

    Full Text Available For almost a century, radio stations have been some primary sources for presenting arts, entertainment, news, etc. and the primary concern on many studies is to understand audience attitude on this media. This paper attempts to investigate audience attitude on radio programs broadcasted in city of Esfahan, Iran. The proposed study selects random sample of 600 out of 1,745,428 residence of this city where 345 people actively were listening to these programs, actively. All questions were designed in Likert scale and Cronbach alpha was 0.941, which was well above the desirable level and validated the survey. According our survey, the most popular part of radio programs was associated with news where 78.3% of the audiences were listening to these programs. According to our survey, audiences were mostly satisfied with family oriented programs and the mean score was 4.05. The other observation indicates that people have good attitude towards educational guidance programs (mean=3.37 and programs related to people and officials (mean=3.41. The results of Freedman test with Chi-Square value of 52.507 determines that there is meaningful difference among different components (mean difference = -0.23 and P-value =0.022. We have also performed an investigation to find out whether there is any difference between different components of this survey in terms of participants’ personal characteristics such as age, gender, educational background and job. Our survey only confirms the mean difference in terms of job specifications and other personal characteristics did not have any impact on people’s attitude. The other observation in our survey indicates that there is a difference between students and people with no job or housekeeper on their attitudes towards educational programs.

    Excessive growth in extraction of underground water resources leads to increase in Karsty trend of aquifer that in addition to severe shortage of water table and saltiness of aquifer will cause ground settlement and creation of sinkholes. Ground settlement and sinkholes creation are destructive phenomena that in recent years have been observed in most parts of Iran and they also have been led to irrevocable damages. Continuous geoelectric and polarization surveys could be assumed as a confident and inexpensive method to study Karsty trend in aquifer, and in this case study the Gheidar Plain Aquifer have been investigated. The research showed that the geoelectric and polarization surveys are in common with excavation studies. Keywords: Karst, ground settlement, sinkhole, geoelectric, polarization, aquifer

    With the recent development of more sensitive biomarkers to assess kidney injury preclinically, a survey was designed i) to investigate what strategies are used to investigate renal toxicity in both ICH S7A compliant Safety Pharmacology (SP) studies after a single dose of a compound and within repeat-dose toxicity studies by large pharmaceutical companies today; ii) to understand whether renal SP studies have impact or utility in drug development and/or if it may be more appropriate to assess renal effects after multiple doses of compounds; iii) to ascertain how much mechanistic work is performed by the top 15 largest pharmaceutical companies (as determined by R&D revenue size); iv) to gain an insight into the impact of the validation of DIKI biomarkers and their introduction in the safety evaluation paradigm; and v) to understand the impact of renal/urinary safety study data on progression of projects. Two short anonymous surveys were submitted to SP leaders of the top 15 pharmaceutical companies, as defined by 2012 R&D portfolio size. Fourteen multiple choice questions were designed to explore the strategies used to investigate renal effects in both ICH S7A compliant SP studies and within toxicology studies. A 67% and 60% response rate was obtained in the first and second surveys, respectively. Nine out of ten respondent companies conduct renal excretory measurements (eg. urine analysis) in toxicology studies whereas only five out of ten conduct specific renal SP studies; and all of those 5 also conduct the renal excretory measurements in toxicology studies. These companies measure and/or calculate a variety of parameters as part of these studies, and also on a case by case basis include regulatory qualified and non-qualified DIKI biomarkers. Finally, only one company has used renal/urinary functional data alone to stop a project, whereas the majority of respondents combine renal data with other target organ assessments to form an integrated decision-making set

    Bernard, J.

    2012-12-01

    The Manufacturers of geophysical instruments have been facing these past decades the fast evolution of the electronics and of the computer sciences. More automatisms have been introduced into the equipment and into the processing and interpretation software which may let believe that conducting geophysical surveys requires less understanding of the method and less experience than in the past. Hence some misunderstandings in the skills that are needed to make the geophysical results well integrated among the global information which the applied geologist needs to acquire to be successful in his applications. Globally, the demand in geophysical investigation goes towards more penetration depth, requiring more powerful transmitters, and towards a better resolution, requiring more data such as in 3D analysis. Budgets aspects strongly suggest a high efficiency in the field associated to high speed data processing. The innovation is required in all aspects of geophysics to fit with the market needs, including new technological (instruments, software) and methodological (methods, procedures, arrays) developments. The structures in charge of the geophysical work can be public organisations (institutes, ministries, geological surveys,…) or can come from the private sector (large companies, sub-contractors, consultants, …), each one of them getting their own constraints in the field work and in the processing and interpretation phases. In the applications concerning Groundwater investigations, Mining Exploration, Environmental and Engineering surveys, examples of data and their interpretation presently carried out all around the world will be presented for DC Resistivity (Vertical Electrical Sounding, 2D, 3D Resistivity Imaging, Resistivity Monitoring), Induced Polarisation (Time Domain 2D, 3D arrays for mining and environmental), Magnetic Resonance Sounding (direct detection and characterisation of groundwater) and Electromagnetic (multi-component and multi

    Abstract Marine mammal stranding events are used as an important tool for understanding cetacean biology worldwide. Nonetheless, there are vast gaps of knowledge to be filled in for a wide range of species. Reputable information is required regarding species from large baleen whales to sperm and beaked whales, as well as pelagic dolphins. This paper describes new cetacean records from north and north-eastern Brazil, which are both the least surveyed areas regarding aquatic mammals. Regular beach surveys were conducted to recover cetacean carcasses along the coast of Pará beginning November 2005. At the coasts of the Maranhão and Piauí states, the surveys were conducted between 2003 and 2013. From 2003 to 2014, 34 strandings of cetaceans were registered. The study provides four additional species records’ in the area based on strandings (Balaenoptera borealis, Balaenoptera physalus, Peponocephala electra, and Pseudorca crassidens). A mass stranding of Guiana dolphins (Sotalia guianensis, N = 12), the most common species for the region, was reported for the first time. The records presented herein are of special concern, since they expand the knowledge on cetaceans from the Brazilian coast. In addition, this study conducted an analysis to verify the similarity between cetacean compositions described for north and north-eastern Brazil and the southern Caribbean region. The results showed a high similarity between these regions, proving the connection with the Caribbean cetacean fauna. PMID:29118593

    Full Text Available Marine mammal stranding events are used as an important tool for understanding cetacean biology worldwide. Nonetheless, there are vast gaps of knowledge to be filled in for a wide range of species. Reputable information is required regarding species from large baleen whales to sperm and beaked whales, as well as pelagic dolphins. This paper describes new cetacean records from north and north-eastern Brazil, which are both the least surveyed areas regarding aquatic mammals. Regular beach surveys were conducted to recover cetacean carcasses along the coast of Pará beginning November 2005. At the coasts of the Maranhão and Piauí states, the surveys were conducted between 2003 and 2013. From 2003 to 2014, 34 strandings of cetaceans were registered.

    Technological advances have made it easier for researchers to collect more frequent longitudinal data from survey respondents via personal computers, smartphones, and other mobile devices. Although technology has led to an increase in data-intensive longitudinal studies, little is known about attrition from such studies or the differences between respondents who complete frequently administered surveys in a timely manner, and respondents who do not. We examined respondent characteristics and behaviors associated with continued and on-time participation in a population-based intensive longitudinal study, using weekly web-based survey interviews over an extended period. We analyzed data from the Relationship Dynamics and Social Life study, an intensive longitudinal study that collected weekly web-based survey interviews for 2.5 years from 1003 18- and 19-year-olds to investigate factors shaping the dynamics of their sexual behavior, contraceptive use, and pregnancies. Ordinary least squares and logistic regression analyses showed background respondent characteristics measured at baseline were associated with the number of days respondents remained enrolled in the study, the number of interviews they completed, and the odds that they were late completing interviews. In addition, we found that changes in pregnancy-related behaviors reported in the weekly interviews were associated with late completion of interviews. Specifically, after controlling for sociodemographic, personality, contact information, and prior experience variables, we found that weekly reports such as starting to have sex (odds ratio [OR] 1.17, 95% CI 1.03-1.32, P=.01), getting a new partner (OR 1.76, 95% CI 1.53-2.03, Psurvey completion. However, young women who reported changes in pregnancy-related behaviors also had lower levels of study attrition, and completed more interviews overall, than did their counterparts. We found that measures of participation in a longitudinal study with weekly web

    The report presents detailed ground magnetic measurements carried out on an 11.1 km2 area in the Forsmark site investigation area. The main objective of this activity is to determine a detailed ground magnetic representation of the bedrock. The results from previous surveys were encouraging and have led to a broad geophysical programme for investigation of lineaments at Forsmark. This report comprises the results from the second and final phase of the extended survey programme and a compilation and summary of all phases in the programme. On ground and on lake ice, a grid with parallel lines was staked. Measurements of the magnetic total field were carried out along profiles, perpendicular to the staked lines, with a profile spacing of 10 m and a station spacing of 5 m. Measurements on the ice-covered sea bays were carried out by a two man crew. One crew member walked along the survey lines, carrying a RTK-GPS guiding the other crew member who measured the magnetic total field. No seaborne survey was carried out in the final phase. Previously, using a high accuracy RTK-GPS unit for boat navigation gave a seaborne survey grid of on average 10 m line spacing and 2-3 m station spacing. In total 427,238 magnetic survey stations have been measured and an area of 4.7 km2 has been surveyed from boat. The magnetic pattern in the survey area can be divided into six main areas with different magnetic character. Along the southwest margin of the survey area the magnetic pattern is intensely banded with rapidly changing low and highly magnetic bands striking southeast-northwest, which to the northeast changes to a gentler, banded pattern of low to moderate magnetic intensity. To the northeast, at the SFR office and along the coastline to the southeast, the pattern is again intensely banded with, southeast-northwest trending, rapidly changing low and highly magnetic bands. These two banded structures probably forms fold limbs of a common fold with a northwest oriented fold axis

    There is little consensus regarding many post-cardiac arrest care parameters. Variability in such practices could confound the results and generalizability of post-arrest care research. We sought to characterize the variability in post-cardiac arrest care practice in Korea and the United States. A 54-question survey was sent to investigators participating in one of two research groups in South Korea (Korean Hypothermia Network [KORHN]) and the United States (National Post-Arrest Research Consortium [NPARC]). Single investigators from each site were surveyed (N = 40). Participants answered questions based on local institutional protocols and practice. We calculated descriptive statistics for all variables. Forty surveys were completed during the study period with 30 having greater than 50% of questions completed (75% response rate; 24 KORHN and 6 NPARC). Most centers target either 33°C (N = 16) or vary the target based on patient characteristics (N = 13). Both bolus and continuous infusion dosing of sedation are employed. No single indication was unanimous for cardiac catheterization. Only six investigators reported having an institutional protocol for withdrawal of life-sustaining therapy (WLST). US patients with poor neurological prognosis tended to have WLST with subsequent expiration (N = 5), whereas Korean patients are transferred to a secondary care facility (N = 19). Both electroencephalography modality and duration vary between institutions. Serum biomarkers are commonly employed by Korean, but not US centers. We found significant variability in post-cardiac arrest care practices among US and Korean medical centers. These practice variations must be taken into account in future studies of post-arrest care.

    Data from the Geological Survey of South Africa's regional geochemical programme is discussed with particular reference to environmental and agricultural aspects. Stream sediments from the Okiep copper district, Namaqualand in South Africa show highly elevated copper values as the result of a history of mining activity in the area. The potential for contamination of forage and drinking water was investigated and no obvious clinical evidence of copper excesses was observed in the ecosystem.

    Psychiatry residents have numerous online educational resources readily available to them although currently there are no data regarding residents' use and perception of such websites. A survey was offered to 62 residents from all four years of training as well as recent graduates of a single psychiatry residency training program. Residents reported utilizing online resources on average 68 % of the time, in comparison to 32 % on average for printed materials. Residents reported UpToDate, PubMed, and Wikipedia as the most visited websites and ranked each highly but for different purposes. Thirty-five percent of residents felt that insufficient faculty guidance was a barrier to use of these educational websites. Pilot data indicate psychiatry residents use online resources daily for their education in various settings. Resident perceptions of individual website's trustworthiness, ease of use, and sources of clinical decision-making and personal learning suggest potential opportunities for educators to better understand the current use of these resources in residency training. Reported barriers including lack of faculty guidance suggest opportunities for academic psychiatry. Further study is necessary at multiple sites before such results may be generalized.

    South Asians represent a rapidly growing part of the U.S. population, increasing 188 percent from 1990 to 2000 (0.27% to 0.78%). Studies investigating the epidemiology of skin disorders in South Asian Americans are lacking. We sought to determine common skin conditions and concerns among this population. This was a community-based survey study. The IRB-approved survey tool was distributed to South Asians adults in the New York City area. All data was self-reported. 190 surveys were completed. 54 percent of responders were female and 46 percent were male. The age of participants ranged from 18-74 years. The respondents were predominantly foreign born (76%), but a large minority (32%) reported living in the U.S. for over 20 years. Nearly half (49%) of the study population reported having visited a dermatologist in the past. The five most common dermatologic diagnoses included: acne (37%), eczema (22%), fungal infection (11%), warts (8%) and moles (8%). The five most common concerns included: dry skin (25%), hair loss (22%), uneven tone (21%), dark spots (18%) and acne (17%). Our results suggest that the leading skin conditions and concerns in South Asian Americans are similar to those reported in other populations with skin of color.

    This interim report is designed to show the present status of the Geological Survey's information and the parts of a comprehensive program necessary to improve our information about the raw material resources of uranium and thorium. Rarely in geologic work has it been necessary. to determine so completely a nation's resources of useful minerals in so brief a span of time. Ordinarily, information on mineral resources Is accumulated during a long period of years. However, uranium and thorium were suddenly thrust from a position of subsidiary economic interest into one of great strategic importance. Information concerning their occurrence must, therefore, be obtained as rapidly as reliable methods of investigation will permit. Accordingly the program must be at once comprehensive and carried out over an area more extensive than is usual in the search for and appraisal of most other mineral resources.

    Although the World Health Organization recommends contact investigations around air travel-associated sputum smear-positive tuberculosis (TB) patients, evidence suggests that the information thus obtained may have overestimated the risk of TB infection because it involved some contacts born in countries with high TB burden who were likely to have been infected with TB in the past, or because tuberculin skin tests were used, which are less specific than the interferon gamma release assay (IGRA) particularly in areas where Bacillus Calmette-Guérin (BCG) vaccination coverage is high. We conducted a questionnaire survey on air travel-associated TB contact investigations in local health offices of Japan from 2012 to 2015, focusing on IGRA positivity. Among 651 air travel-associated TB contacts, average positivity was 3.8% (95% confidence interval (CI): 2.5-5.6) with a statistically significant increasing trend with older age (p < 0.0094). Positivity among 0-34 year-old contacts was 1.0% (95% CI: 0.12-3.5%), suggesting their risk of TB infection is as small as among Japanese young adults with low risk of TB infection (positivity: 0.85-0.90%). Limiting the contact investigation to fewer passengers (within two seats surrounding the index case, rather than two rows) seems reasonable in the case of aircraft with many seats per row.

    Full Text Available Abstract Background Overweight and obesity are associated with increased risk for pregnancy complications. Knowledge about increased risks in overweight and obese women could contribute to successful prevention strategies and the aim of this study is to assess current levels of knowledge in a pregnant population. Methods Cross sectional survey of 412 consecutive unselected women in early pregnancy in Brisbane, Australia: 255 public women attending their first antenatal clinic visit and 157 women at private maternal fetal medicine clinics undergoing a routine ultrasound evaluation prior to 20 weeks gestation. The cohort was stratified according to pre pregnancy BMI ( Results Over 75% of respondents identified that obese women have an increased risk of overall complications, including gestational diabetes and hypertensive disorders of pregnancy compared to women of normal weight. More than 60% of women asserted that obesity would increase the risk of caesarean section and less than half identified an increased risk of adverse neonatal outcomes. Women were less likely to know about neonatal complications (19.7% did not know about the effect of obesity on these than maternal complications (7.4%. Knowledge was similar amongst women recruited at the public hospital and those recruited whilst attending for an ultrasound scan at a private clinic. For most areas they were also similar between women of lower and higher BMI, but women with BMI Conclusions Many women correctly identify that overweight and obesity increases the overall risk of complications of pregnancy and childbirth. The increased risks of maternal complications associated with being obese are better known than the increased risk of neonatal complications. Maternal education status is a main determinant of the extent of knowledge and this should be considered when designing education campaigns.

    Quality of life is a complex construct that affects the overall life satisfaction, emotional well-being, and functioning of individuals. The aim of our study was to assess the quality of life of dental students at one U.S. dental school, using the World Health Organization Quality of Life (WHOQOL)-BREF, a multi-dimensional, cross-cultural, validated, and reliable survey instrument. Of the 1,437 students invited to participate, 401 students responded, but 17 were excluded because of missing data. The final sample consisted of 384 students for an overall response rate of 27%: response rates by year were first year 32.6%, second year 16.9%, third year 26.6%, and fourth year 24.0%. The results showed that the responding students rated their overall quality of life as good. The Physical Health domain had the highest mean score, while the Psychological domain had the lowest. Females reported higher quality of life than males in the Social Relationships domain. Single students were found to have a lower perceived quality of life than married students. Older students were found to have lower perceived quality of life in the Physical Health and Environment domains. Physical Health domain scores were significantly higher for fourth-year than first-year respondents, while Psychological domain scores were significantly lower for third-year than first-year respondents. Further research is needed to explore the effect of dental school on the quality of life of dental students. Targeted programs to impact students' quality of life at various points in the curriculum may be beneficial.

    A plan for actively achieving green energy obligation is a strategic tool for policies that point forward the diminution of the fossil fuel consumption and greenhouse gas (GHG) in conformity with the Paris environment-friendly accords (COP21) and updates of other ecosystem agreements. To achieve the concrete implementation of the sustainable energy strategy (SES) and to accomplish its objectives, an investigation is a critical factor. SES investigation has to consider both the advancement of each particular action and its wide-ranging green effect, which necessitates multiple levels of improvement. In this study, a consolidated eco strategy for evaluating, monitoring and handling the SES via investigation and execution process is established. The city of Nairobi was used as one of the geographical positions to test the effectiveness of this approach and to investigate its robust and weak points. Specifically, benefit-cost analysis, reliability, peer review and general level of participation were renowned as vital tools for attaining a functional SES investigation and for then drafting successful energy guidelines. Some suggestions were put forward to highlight the research and execution methods and to draw a road map of how SES can be strategically placed into practice.

     NHS Library Services are utilised by NHS staff and junior trainees to locate scientific papers that provide them with the evidence base required for modern medical practice. The cost of accessing articles can be considerable particularly for junior trainees.  This survey looks at variations in cost of journal article loans and investigates access to particular orthopaedic journals across the country.  A national survey of UK Health Libraries was performed. Access to and costs of journals and interlibrary loan services were assessed. Availability of five wide-reaching orthopaedic journals was investigated.  Seven hundred and ten libraries were identified. One hundred and ten libraries completed the questionnaire (16.7%). Of these, 96.2% reported free access to scientific journals for users. 99.1% of libraries used interlibrary loan services with 38.2% passing costs on to the user at an average of £2.99 per article. 72.7% of libraries supported orthopaedic services. Journal of Bone and Joint Surgery (British) had greatest onsite availability.  The study demonstrates fluctuations in cost of access to interlibrary loan services and variation in access to important orthopaedic journals. It provides a reflection of current policy of charging for the acquisition of medical evidence by libraries in the UK. © 2012 The authors.

    Full Text Available Abstract Background The epidemiology of gastroesophageal reflux disease (GERD has yet to be investigated using the symptomatic threshold criteria recommended by the Montreal Definition. This study aimed to determine the prevalence of symptom-defined GERD across five regions of China, and to investigate variables associated with GERD. Methods A representative sample of 18 000 adults (aged 18-80 years were selected equally from rural and urban areas in each region (n = 1800. According to the Montreal Definition, GERD is present when mild symptoms of heartburn and/or regurgitation occur on ≥2 days a week, or moderate-to-severe symptoms of heartburn and/or regurgitation occur on ≥1 day a week. Results In total, 16 091 participants completed the survey (response rate: 89.4% and 16 078 responses were suitable for analysis. Applying the Montreal criteria, the prevalence of symptom-defined GERD was 3.1% and varied significantly (p Conclusions This population-based survey found that the prevalence of symptom-defined GERD in China was 3.1%, which is lower than that found in Western countries.

    Previous research has shown the importance of urgent initiation of antiplatelet therapy after transient ischemic attack (TIA) to reduce the risk of stroke. Many hospitals in the Netherlands have therefore implemented rapid pathways for assessment of patients with TIA. Dutch stroke guidelines lack clear directives for organization of TIA assessment and thus allow for variation. The aim of this study was to investigate variation in organization of TIA assessment in Dutch hospitals. One neurologist per hospital (of 88 Dutch hospitals) with special interest in stroke was invited to participate in a web-based survey addressing the organization, content, and timing of TIA assessment. Seventy (80%) neurologists completed the survey, all of whom reported performing TIA assessment in their hospital. There was considerable variation in the method of application and the location of assessment. In 10% of the hospitals, patients with TIA are always admitted to the ward. The content of diagnostics is fairly similar, but hospitals vary in the extent of cardiological workup. Almost all hospitals aim for a swift start of assessment as directed by guidelines, but access time differs. Eighty-six percent of respondents reported that antiplatelet therapy is usually initiated before assessment, based on history. This study showed variation in organization of TIA assessment in Dutch hospitals, especially regarding location within the hospital, time to assessment after announcement, and cardiological workup. Further research is needed to investigate implications of this variation for quality of care. Copyright © 2017 National Stroke Association. Published by Elsevier Inc. All rights reserved.

    2014-12-01

    Full Text Available Authors in their works study vibroimpact system dynamic behaviour by numerical parametric continuation technique combined with shooting and Newton-Raphson’s methods. The technique is adapted to two-mass two-degree-of-freedom vibroimpact system under periodic excitation. Impact is simulated by nonlinear contact interaction force based on Hertz’s contact theory. Stability or instability of obtained periodic solutions is determined by monodromy matrix eigenvalues (multipliers based on Floquet’s theory. In the present paper we describe the state of problem of parameter continuation method using for nonlinear tasks solution. Also we give the short survey of numerous contemporary literature in English and Russian about parameter continuation method application for nonlinear problems. This method is applied for vibroimpact problem solving more rarely because of the difficulties connected with repeated impacts.

    2013-04-01

    The economic repercussions of mental disorders in the workplace are vast. Research has found that individuals in high-stress jobs tend to have higher prevalence of mental disorders. The current cross-sectional study examined the relationships between work-related stress and mental disorders in a recent representative population-based sample-the 2010 Canadian Community Health Survey by Statistics Canada (CCHS; 2010a; Retrieved from http://www23.statcan.gc.ca/imdb-bmdi/instrument/3226_Q1_V7-eng.pdf). Respondents in the highest level of perceived work stress had higher odds of ever being treated for an emotional or mental-health problem and for being treated in the past 12 months. These high-stress respondents also had higher odds of being diagnosed for mood and anxiety disorders than their nonstressed counterparts. These associations highlight the continued need to examine and promote mental health and well-being in the workplace.

  20. Literature survey: Relations between stress change, deformation and transmissivity for fractures and deformation zones based on in situ investigations

    This literature survey is focused upon relations between stress change, deformation and transmissivity for fractures and deformation zones and aims at compiling and commenting on relevant information and references with focus on data from in situ investigations. Main issues to investigate are: - Impact of normal stress change and deformation on transmissivity, for fractures and deformation zones. - Impact of shear stress and displacement on transmissivity, for fractures and deformation zones for different normal load conditions. Considering the line of research within the area, the following steps in the development can be identified. During the 1970's and 1980's, the fundamentals of rock joint deformation were investigated and identification and description of mechanisms were made in the laboratory. In the 1990's, coupling of stress-flow properties of rock joints were made using hydraulic testing to identify and describe the mechanisms in the field. Both individual fractures and deformation zones were of interest. In situ investigations have also been the topic of interest the last ten years. Further identification and description of mechanisms in the field have been made including investigation and description of system of fractures, different types of fractures (interlocked/mated or mismatched/unmated) and how this is coupled to the hydromechanical behavior. In this report, data from in situ investigations are compiled and the parameters considered to be important to link fracture deformation and transmissivity are normal stiffness, k{sub n} and hydraulic aperture, b{sub h}. All data except for those from one site originate from investigations performed in granitic rock. Normal stiffness, k{sub n}, and hydraulic aperture, b{sub h}, are correlated, even though data are scattered. In general, the largest variation is seen for small hydraulic apertures and high normal stiffness. The increasing number of contact points (areas) and fracture filling are

    One of the most significant challenges in large-scale climate modeling, as well as in high-performance computing in other scientific fields, is that of effectively integrating many software models from multiple contributors. A software framework facilitates the integration task, both in the development and runtime stages of the simulation. Effective software frameworks reduce the programming burden for the investigators, freeing them to focus more on the science and less on the parallel communication implementation. while maintaining high performance across numerous supercomputer and workstation architectures. This document surveys numerous software frameworks for potential use in Earth science modeling. Several frameworks are evaluated in depth, including Parallel Object-Oriented Methods and Applications (POOMA), Cactus (from (he relativistic physics community), Overture, Goddard Earth Modeling System (GEMS), the National Center for Atmospheric Research Flux Coupler, and UCLA/UCB Distributed Data Broker (DDB). Frameworks evaluated in less detail include ROOT, Parallel Application Workspace (PAWS), and Advanced Large-Scale Integrated Computational Environment (ALICE). A host of other frameworks and related tools are referenced in this context. The frameworks are evaluated individually and also compared with each other.

    Detection of animals during visual surveys is rarely perfect or constant, and failure to account for imperfect detectability affects the accuracy of abundance estimates. Freshwater cetaceans are among the most threatened group of mammals, and visual surveys are a commonly employed method for estimating population size despite concerns over imperfect and unquantified detectability. We used a combined visual-acoustic survey to estimate detectability of Ganges River dolphins (Platanista gangetica gangetica) in four waterways of southern Bangladesh. The combined visual-acoustic survey resulted in consistently higher detectability than a single observer-team visual survey, thereby improving power to detect trends. Visual detectability was particularly low for dolphins close to meanders where these habitat features temporarily block the view of the preceding river surface. This systematic bias in detectability during visual-only surveys may lead researchers to underestimate the importance of heavily meandering river reaches. Although the benefits of acoustic surveys are increasingly recognised for marine cetaceans, they have not been widely used for monitoring abundance of freshwater cetaceans due to perceived costs and technical skill requirements. We show that acoustic surveys are in fact a relatively cost-effective approach for surveying freshwater cetaceans, once it is acknowledged that methods that do not account for imperfect detectability are of limited value for monitoring.

    Worldwide we are facing a serious demographic challenge due to the dramatic growth of the population over 60 years. It is expected that the proportion of this population will nearly double from 12 to 22 %, between 2015 and 2050. This demographic shift comes with major health and socio-economic concerns. Nutrition is a fundamental determinant of both health and disease and its role in extending a healthy lifespan is the object of considerable research. Notably, malnutrition is one of the main threats to health and quality of life among the elderly. Therefore, knowledge about nutritional status among the elderly is essential for the promotion and maintenance of healthy ageing and to support the development of health protection policies and equity in elderly health care. This is a nationwide nutrition survey of the Portuguese population over 65 years old, with data collection through face-to-face interviews. A representative and random sample of community dwelling elderly and nursing homes residents will be obtained by multistage sampling stratified per main Portuguese regions, sex and age groups. Minimum sample size was estimated to be 2077 elderly (979 in the community and 1098 in nursing homes). Data will be collected on food habits and eating patterns, nutritional status, food insecurity, lifestyle, self-rated general health status and self-reported diseases, functionality, loneliness, cognitive function, emotional status and demographic and socio-economic characterization. This is the first national survey to evaluate the prevalence of nutritional risk and malnutrition of the Portuguese population above 65 years old, including those living in nursing homes. It will allow the identification of population subgroups of elderly with increased odds of malnutrition and nutritional risk. In addition, this survey will contribute to the identification of psychosocial and clinical predictors of malnutrition among elderly, which is an important risk factor for other

    A survey of hydrocephalus in cattle in North Dakota in 1975 and 1976 included 26 proven cases falling into categories comparable to that seen in the human situation. The largest group was hydrocephalus secondary to aqueductal stenosis with the second largest group being hydranencephaly. Other groups included the Dandy-Walker malformation, porencephaly and a miscellaneous group having a variety of central nervous system malformations. All cases were sporadic with no evidence to suggest a genetic basis. The similarity suggests that calves could serve as a useful model for the human situation.

    Full Text Available In this paper we present the latest experiences carried out by our research group in the field of multimedia communication. Starting from the construction of virtual models, interactive and non-interactive, we pursued the aim to introduce edutainment paths in some museum contexts, both increasing the value of cultural assets and creating an attractive pole for the visitors. The current trends are gradually transforming museums from static places of conservation into active and engaging spaces to deliver accessible culture to the masses, using digital technologies for creating new paradigms of interaction and enhance the experience of the visitor. Here we present two case studies, whose purpose is to bring together the different competences by various experts to test the potential of digital products as non-formal teaching tools to allow a satisfying learning experience. The case explored are those of the Civic Museum of Schifanoia (Ferrara and the octagonal cloister of the Carracci in San Michele in Bosco (Bologna. The multimedia products discussed here relate to these two research themes, and up to now 3 out of 5 planned products have been made (in final mode, or in prototype form. The experimentation led to concrete results that introduced a reflection on what investigative methodologies and protocols are more suitable to be adopted in these cases, in compliance to the aim identified by the project.

    Allied health professionals frequently use surveys to collect data for clinical practice and service improvement projects. Careful development and piloting of purpose-designed surveys is important to ensure intended measuring (that respondents correctly interpret survey items when responding). Cognitive interviewing is a specific technique that can improve the design of self-administered surveys. The aim of this study was to describe the use of the cognitive interviewing process to improve survey design, which involved a purpose-designed, online survey evaluating staff use of functional electrical stimulation. A qualitative study involving one round of cognitive interviewing with three occupational therapists and three physiotherapists. The cognitive interviewing process identified 11 issues with the draft survey, which could potentially influence the validity and quality of responses. The raised issues included difficulties with: processing the question to be able to respond, determining a response to the question, retrieving relevant information from memory and comprehending the written question. Twelve survey amendments were made following the cognitive interviewing process, comprising four additions, seven revisions and one correction. The cognitive interviewing process applied during the development of a purpose-designed survey enabled the identification of potential problems and informed revisions to the survey prior to its use. © 2017 Occupational Therapy Australia.

    . Charcoal, molluscan and fish remains, basalt tools, and other artifacts were recovered. This material, while providing an extremely small sample, will greatly enhance our understanding of the use of the area. Recommendations regarding the need for further investigation and the preservation of sites within the project corridor are suggested. All sites within the project corridor must be considered potentially significant at this juncture. Further archaeological investigation consisting of a full inventory survey will be required prior to a final assessment of significance for each site and the development of a mitigation plan for sites likely to be impacted by the Hawaii Geothermal Project.

  13. A simulation study of acoustic-assisted tracking of whales for mark-recapture surveys.

    Directory of Open Access Journals (Sweden)

    David Peel

    Full Text Available Collecting enough data to obtain reasonable abundance estimates of whales is often difficult, particularly when studying rare species. Passive acoustics can be used to detect whale sounds and are increasingly used to estimate whale abundance. Much of the existing effort centres on the use of acoustics to estimate abundance directly, e.g. analysing detections in a distance sampling framework. Here, we focus on acoustics as a tool incorporated within mark-recapture surveys. In this context, acoustic tools are used to detect and track whales, which are then photographed or biopsied to provide data for mark-recapture analyses. The purpose of incorporating acoustics is to increase the encounter rate beyond using visual searching only. While this general approach is not new, its utility is rarely quantified. This paper predicts the "acoustically-assisted" encounter rate using a discrete-time individual-based simulation of whales and survey vessel. We validate the simulation framework using existing data from studies of sperm whales. We then use the framework to predict potential encounter rates in a study of Antarctic blue whales. We also investigate the effects of a number of the key parameters on encounter rate. Mean encounter rates from the simulation of sperm whales matched well with empirical data. Variance of encounter rate, however, was underestimated. The simulation of Antarctic blue whales found that passive acoustics should provide a 1.7-3.0 fold increase in encounter rate over visual-only methods. Encounter rate was most sensitive to acoustic detection range, followed by vocalisation rate. During survey planning and design, some indication of the relationship between expected sample size and effort is paramount; this simulation framework can be used to predict encounter rates and establish this relationship. For a case in point, the simulation framework indicates unequivocally that real-time acoustic tracking should be considered for

    2014-05-01

    The World Anti-Doping Agency (WADA) is introducing enhancements to doping investigations in its 2015 Code, which include improved sharing of information between antidoping organisations (including sporting bodies) and enhanced accountability of athlete support staff. These additions will improve the control of links between sports doping and organised crime. In February 2013 the Australian Crime Commission released a report that linked several professional sporting codes, professional athletes with links to organised crime, performance enhancing drugs and illicit substances. Following this report the Australian Football League (AFL) partnered the Australian national antidoping organisation to investigate peptide use in Australian football. This review compared the model proposed by Marclay, a hypothetical model for anti-doping investigations that proposed a forensic intelligence and analysis approach, to use the forensic capabilities of the AFL investigation to test the model's relevance to an actual case. The investigation uncovered the use of peptides used to enhance athlete performance. The AFL investigation found a high risk of doping where athlete support staff existed in teams with weak corporate governance controls. A further finding included the need for the investigation to provide a timely response in professional team sports that were sensitive to the competition timing. In the case of the AFL the team was sanctioned prior to the finals as an interim outcome for allowing the risk of use of performance-enhancing substances. Doping violation charges are still being considered. Antidoping strategies should include the investigation of corporate officers in team doping circumstances, the mandatory recording of all athlete substance use during competition and training phases, the wider sharing of forensic intelligence with non-sporting bodies particularly law enforcement and collaboration between antidoping and sporting organisations in doping investigations

    We present the Strong Lensing Legacy Survey-ARCS (SARCS) sample compiled from the final T0006 data release of the Canada-France-Hawaii Telescope Legacy Survey (CFHTLS) covering a total non-overlapping area of 159 deg2. We adopt a semi-automatic method to find gravitational arcs in the survey that makes use of an arc-finding algorithm. The candidate list is pruned by visual inspection and ranking to form the final SARCS sample. This list also includes some serendipitously discovered lens candidates which the automated algorithm did not detect. The SARCS sample consists of 127 lens candidates which span arc radii ~2''-18'' within the unmasked area of ~150 deg2. Within the sample, 54 systems are promising lenses among which, we find 12 giant arcs (length-to-width ratio >=8). We also find two radial arc candidates in SL2SJ141447+544704. From our sample, we detect a systematic alignment of the giant arcs with the major axis of the baryonic component of the putative lens in concordance with previous studies. This alignment is also observed for all arcs in the sample and does not vary significantly with increasing arc radius. The mean values of the photometric redshift distributions of lenses corresponding to the giant arcs and all arcs sample are at z ~ 0.6. Owing to the large area and depth of the CFHTLS, we find the largest sample of lenses probing mass scales that are intermediate to cluster and galaxy lenses for the first time. We compare the observed image separation distribution (ISD) of our arcs with theoretical models. A two-component density profile for the lenses which accounts for both the central galaxy and the dark matter component is required by the data to explain the observed ISD. Unfortunately, current levels of uncertainties and degeneracies accommodate models both with and without adiabatic contraction. We also show the effects of changing parameters of the model that predict the ISD and that a larger lens sample might constrain relations such as the

    In psychiatric care practice, patients are often seen who have difficulty with their social lives due to protracted psychiatric symptoms despite years without drug abuse. The difficulty of dealing with such cases and the lack of preparedness of the legal system leave circumstantial care as the only option. Western.countries have recently begun using the name 'concurrent disorder' as a diagnosis for patients deemed unable to recover solely through such treatment for drug addiction, signifying the presence of both a substance use disorder (SUD) and a mental health disorder. Various assessment and intervention methods are being investigated, and many studies have been reported. Based on the hypothesis that Drug Addiction Rehabilitation Center (DARC) are partly involved in supporting those with psychotic concurrent disorders (PSCD) in Japan, we conducted a survey to clarify the actual support for PSCD patients at DARC and the challenges they face. Surveys were administered to DARC-related institutions all over Japan (44 governing organizations and 66 institutions). Complete responses from 86 full-time employees and 445 DARC users were analyzed. DARC users were divided into two groups: psychiatric concurrent disorders (PSCD group, n = 178) and those without such symptoms (SUD group, n = 267), with the PSCD group accounting for 40% of the DARC users surveyed. Compared to the SUD group, the PSCD group was significantly less satisfied with their lifestyle and interpersonal relations at the DARC and a significantly higher proportion of the PSCD group requested assistance in communicating with others. When employees were presented with a hypothetical PSCD case and asked what was needed to deal with it, some responses were, "an institution that can treat both drug addiction and other mental health disorders," "a psychiatric care institution that provides 24-hour care," and "sufficient manpower and training." In the future, a treatment system must be established based on

    1995-04-01

    This report details the archaeological investigation of a 200 foot wide sample corridor extending approximately 9 miles along the southern portion of Maui within the present districts of Hana and Makawao. The survey team documented a total of 51 archaeological sites encompassing 233 surface features. Archaeological sites are abundant throughout the region and only become scarce where vegetation has been bulldozed for ranching activities. At the sea-land transition points for the underwater transmission cable, both Ahihi Bay and Huakini Bay are subjected to seasonal erosion and redeposition of their boulder shorelines. The corridor at the Ahihi Bay transition point runs through the Maonakala Village Complex which is an archaeological site on the State Register of Historic Places within a State Natural Area Reserve. Numerous other potentially significant archaeological sites lie within the project corridor. It is likely that rerouting of the corridor in an attempt to avoid known sites would result in other undocumented sites located outside the sample corridor being impacted. Given the distribution of archaeological sites, there is no alternative route that can be suggested that is likely to avoid encountering sites. Twelve charcoal samples were obtained for potential taxon identification and radiocarbon analysis. Four of these samples were subsequently submitted for dating and species identification. Bird bones from various locations within a lava tube were collected for identification. Sediment samples for subsequent pollen analysis were obtained from within two lava tubes. With these three sources of information it is hoped that paleoenvironmental data can be recovered that will enable a better understanding of the setting for Hawaiian habitation of the area.

    It is commonly believed that robotic surgery systems provide surgeons with an ergonomically sound work environment; however, the actual experience of surgeons practicing robotic surgery (RS) has not been thoroughly researched. In this ergonomics survey study, we investigated surgeons' physical symptom reports and their association with factors including demographics, specialties, and robotic systems. Four hundred and thirty-two surgeons regularly practicing RS completed this comprehensive survey comprising 20 questions in four categories: demographics, systems, ergonomics, and physical symptoms. Chi-square and multinomial logistic regression analyses were used for statistical analysis. Two hundred and thirty-six surgeons (56.1 %) reported physical symptoms or discomfort. Among those symptoms, neck stiffness, finger, and eye fatigues were the most common. With the newest robot, eye symptom rate was considerably reduced, while neck and finger symptoms did not improve significantly. A high rate of lower back stiffness was correlated with higher annual robotic case volume, and eye symptoms were more common with longer years practicing robotic surgery (p ergonomic settings reported lower symptom report rates. Symptoms were not correlated with age and gender. Although RS provides relatively better ergonomics, this study demonstrates that 56.1 % of regularly practicing robotic surgeons still experience related physical symptoms or discomfort. In addition to system improvement, surgeon education in optimizing the ergonomic settings may be necessary to maximize the ergonomic benefits in RS.

    Dehlsen Associates, LLC was awarded a grant by the United States Department of Energy (DOE) Golden Field Office for a project titled 'Siting Study Framework and Survey Methodology for Marine and Hydrokinetic Energy Project in Offshore Southeast Florida,' corresponding to DOE Grant Award Number DE-EE0002655 resulting from DOE funding Opportunity Announcement Number DE-FOA-0000069 for Topic Area 2, and it is referred to herein as 'the project.' The purpose of the project was to enhance the certainty of the survey requirements and regulatory review processes for the purpose of reducing the time, efforts, and costs associated with initial siting efforts of marine and hydrokinetic energy conversion facilities that may be proposed in the Atlantic Ocean offshore Southeast Florida. To secure early input from agencies, protocols were developed for collecting baseline geophysical information and benthic habitat data that can be used by project developers and regulators to make decisions early in the process of determining project location (i.e., the siting process) that avoid or minimize adverse impacts to sensitive marine benthic habitat. It is presumed that such an approach will help facilitate the licensing process for hydrokinetic and other ocean renewable energy projects within the study area and will assist in clarifying the baseline environmental data requirements described in the U.S. Department of the Interior Bureau of Ocean Energy Management, Regulation and Enforcement (formerly Minerals Management Service) final regulations on offshore renewable energy (30 Code of Federal Regulations 285, published April 29, 2009). Because projects generally seek to avoid or minimize impacts to sensitive marine habitats, it was not the intent of this project to investigate areas that did not appear suitable for the siting of ocean renewable energy projects. Rather, a two-tiered approach was designed with the first step consisting of gaining overall insight

    Background Surveys are a common way to measure annoyance due to road traffic noise, but the method has some draw-backs. Survey context, question wording and answer alternatives could affect participation and answers and could have implications when comparing studies and/or performing pooled analyses. The aim of this study was to investigate the difference in annoyance reporting due to road traffic noise in two types of surveys of which one was introduced broadly and the other with the clearly stated aim of investigating noise and health. Methods Data was collected from two surveys carried out in the municipality of Malmö, southern Sweden in 2007 and 2008 (n = 2612 and n = 3810). The first survey stated an aim of investigating residential environmental exposure, especially noise and health. The second survey was a broad public health survey stating a broader aim. The two surveys had comparable questions regarding noise annoyance, although one used a 5-point scale and the other a 4-point scale. We used geographic information systems (GIS) to assess the average road and railway noise (LAeq,24h) at the participants' residential address. Logistic regression was used to calculate odds ratios for annoyance in relation to noise exposure. Results Annoyance at least once a week due to road traffic noise was significantly more prevalent in the survey investigating environment and health compared to the public health survey at levels > 45 dB(A), but not at lower exposure levels. However no differences in annoyance were found when comparing the extreme alternatives "never" and "every day". In the study investigating environment and health, "Noise sensitive" persons were more likely to readily respond to the survey and were more annoyed by road traffic noise compared to the other participants in that survey. Conclusions The differences in annoyance reporting between the two surveys were mainly due to different scales, suggesting that extreme alternatives are to prefer before

    Seabird distributions and the associated seasonal variations remain challenging to investigate, especially in oceanic areas. Recent advances in telemetry have provided considerable information on seabird ecology, but still exclude small species, non-breeding birds and individuals from inaccessible colonies from any scientific survey. To overcome this issue and investigate seabird distribution and abundance in the eastern North Atlantic (ENA), large-scale aerial surveys were conducted in winter 2011-12 and summer 2012 over a 375,000 km2 area encompassing the English Channel (EC) and the Bay of Biscay (BoB). Seabird sightings, from 15 taxonomic groups, added up to 17,506 and 8263 sightings in winter and summer respectively, along 66,307 km. Using geostatistical methods, density maps were provided for both seasons. Abundance was estimated by strip transect sampling. Most taxa showed marked seasonal variations in their density and distribution. The highest densities were recorded during winter for most groups except shearwaters, storm-petrels, terns and large-sized gulls. Subsequently, the abundance in winter nearly reached one million individuals and was 2.5 times larger than in summer. The continental shelf and the slope in the BoB and the EC were identified as key areas for seabird conservation, especially during winter, as birds from northern Europe migrate southward after breeding. This large-scale study provided a synoptic view of the seabird community in the ENA, over two contrasting seasons. Our results highlight that oceanic areas harbour an abundant avifauna. Since most of the existing marine protected areas are restricted to the coastal fringe, the importance of oceanic areas in winter should be considered in future conservation plans. Our work will provide a baseline for the monitoring of seabird distribution at sea, and could inform the EU Marine Strategy Framework Directive.

    Full Text Available Graduate admissions play a critical gatekeeping role in the physics community not only because they select students who are allowed to begin their graduate studies, but also because they influence how students perceive graduate school, and in some cases whether or not they will even choose to apply. In conjunction with the APS Bridge Program, we conducted a national survey of graduate directors (and related faculty of physics Ph.D. programs in the United States to explore graduate admissions practices. Our focus was on criteria used in determining admissions, mechanisms through which graduate applicants are handled, and how student representation considerations are incorporated into admissions (if at all. We report here on existing graduate admission practices in physics departments and highlight some critical issues for understanding barriers for diversifying graduate physics, including the use of GRE scores (and the relative importance placed on them. We find that the use of a minimum GRE score for admission, a practice in opposition to recommendations made by the tests designers, is reported to be used in many departments (more than one in three. We also find letters of recommendation to be highly valued in admissions decisions. Our data describe various initiatives at the institutional or individual level to increase gender diversity in admissions. A sizable number of departments also express a latent demand for greater numbers of students from traditionally marginalized racial or ethnic groups, but simultaneously report a lack of such applicants.

  17. Combined long term monitoring approach to investigate flow fields and changes in floodplain geomorphology using stationary ADCPs, sediment traps and geodetic surveys

    2017-04-01

    The success of plans and measures to restore floodplains and designate new flood retention areas for rivers depends on a fundamental understanding of the boundary conditions during flood events. Hydraulic conditions interact directly with vegetation and morphology and have a decisive impact on sedimentation and erosion. While the technical development of numerical and physical modelling of floodplain hydraulics has made a great progress during the last decades, up till now field investigations during flood events and for several years are very seldom. In this context, changes in geomorphology and the impact of different types of vegetation structures on the flow field has been systematically studied over a period of several years at floodplain sites of the Upper Rhine. Using sediment traps and geodetic surveys, yearly and spatial changes of sedimentation and erosion as well as the evolution of floodplain geomorphology could be investigated over a period of nine years. Besides this, the overall aim of this investigation was to carry out in situ flow velocity measurements during entire flood events to get better information about the evolution of hydraulics under different conditions and to understand under which circumstances erosion and sedimentation take place at typical riparian vegetation sites. The decisive impact of vegetation on hydraulics was monitored online via remote control for several flood events with two Acoustic Doppler Current Profilers which were mounted at the floodplain bottom. The design of experiment allows comparative studies of flow fields under the influence of different types of riparian vegetation and under non-stationary conditions, for longer periods and with respect to differences in the flow field caused by willows and grass. After completion of the installation in 2001, several investigations were carried out since then. Concerning the results of this experimental design, particular importance is attached to describing and comparing

    Neurophobia is a well-described phenomenon among medical students in many countries. Little is reported concerning the perceptions of neurosciences among medical students in China. We surveyed senior medical students in Wuhan, China, on their perceptions of neuroscience. Students' self-assessments of knowledge in various specialties ranked neurology low, but not the lowest. Students' confidence in diagnosing neurological patients and managing neurological patients demonstrated significant correlation. A positive correlation was noted between confidence in these clinical parameters and the likelihood of specializing in neurology. Students reported bedside teaching and small group sessions as having the greatest value in learning neurology. The low, but not the lowest ranking of self-perceived knowledge in neurology by medical students in Wuhan, China, differs from findings reported in other countries. In this exploratory study the investigators hypothesize that the well-described phenomenon of neurophobia may exhibit a less pronounced influence in Wuhan, China. Copyright © 2014 Elsevier Inc.

    Increased recognition that addictive behaviors tend to be chronic and relapsing has led to a growing emphasis on longitudinal substance abuse research. The purpose of this study was to identify effective follow-up strategies used by National Institute on Drug Abuse-funded investigators who have conducted at least 1 study involving follow-up data collection from human subjects. A web-based survey was administered to a representative sample of National Institute on Drug Abuse-funded researchers (N = 153) with a history of conducting longitudinal research. Reported study response rates were generally high, although 27% of the studies fell below the 80% benchmark. Face-to-face and telephone-based interviews commanded the largest subject payments-2 to 3 times higher than compensation rates for collection of biologic samples. With regard to the presumed impact of low follow-up rates on the generalizability of study findings, one-third of investigators who compared baseline characteristics of those who did and did not participate in the follow-up found meaningful differences. Support was found for the hypothesis that follow-up rates and total compensation would be positively related, with the mean compensation amounts between studies achieving effect in the predicted direction. The majority of respondents reported difficulty in tracking and locating subjects, and study respondents often proved to be quite different from nonrespondents. Incentives improved follow-up rates to a point, although the relationship was not linear. Efforts to improve follow-up rates may be better spent on addressing tracking and locating logistics rather than on strategies to compel participation once the subject has been located.

    To investigate stakeholder perceptions of healthy food availability in school canteens, the promotion of healthy foods and canteen policy compliance. This is a cross-sectional study of Catholic and independent primary and high schools comprising three investigative phases: (i) survey of 39 schools, (ii) survey of canteen managers and parents from 10 schools and (iii) an audit of school menus against National Healthy School Canteen Guidelines. Total participants included: 6 principals, no canteen mangers and 86 parents from two schools; 24 menus were audited. Schools are committed to supporting healthy eating, with participants agreeing canteens should follow the National Health School Canteen Guidelines. A total of 94% of parents (n = 81/86) indicated that their children buy food from the school canteen, with commonly purchased items mostly classified as 'red'. Despite this food choice, parents (n = 32/48) indicated they had a responsibility to encourage healthy eating. No school canteen menu comprised +50% 'green' foods and thus did not comply with the National Healthy School Canteen Guidelines. Despite the intense focus on school canteens to sell healthy food, little has changed in terms of student's food choices and the barriers to providing healthy options. The external environment and divided parental buy-in impact the canteen's ability to comply with guidelines. A holistic approach involving all stakeholder levels is required to successfully achieve a healthy school canteen environment and positively influence student's food habits and choices. © 2017 Dietitians Association of Australia.

    Background. This survey aimed to investigate the characteristics of users and nonusers of herbal medicine and the adverse events experienced due to herbal medicines in South Korea. Methods. The questionnaire consisted of safety, using experience, using type, usage and nonusage reason, purchase location, and adverse events of herbal medicine. The survey was administered by online. Results. Of the total 1,134 respondents, 726 (64.0%) considered herbal medicine safe, and 693 (61.1%) answered that they have taken herbal medicines within the past year. Most common place to purchase them was "TKM hospital or clinic" (63.6%), and most participants (72.2%) took a decoction from a TKM institution. The biggest reason for taking them was for "health improvement" (57.3%), and the reasons for not using them was "medication not necessary" (63.7%). Among those who took herbal medicines, 46 experienced adverse events, and the most frequently reported symptoms were digestive disorders (52.2%). Of the 46 participants who experienced adverse events, 20 (43.5%) were treated by TKM doctors. Conclusions. This study suggests that regulation of herbal medicines is needed in order to resolve problems related to the safety of herbal medicines.

    Background: There are no general strategies or tools to evaluate daily lesson plans; however, assessments conducted using traditional methods usually include course plans. This study aimed to evaluate the strengths and weaknesses of online survey software in collecting data on education in medical fields and the application of such softwares to evaluate students' views and modification of lesson plans. Methods: After investigating the available online survey software, esurveypro was selected for assessing daily lesson plans. After using the software for one semester, a questionnaire was prepared to assess the advantages and disadvantages of this method and students’ views in a cross-sectional study. Results: The majority of the students (51.7%) rated the evaluation of classes per session (lesson plans) using the online survey as useful or very useful. About 51% (n=36) of the students considered this method effective in improving the management of each session, 67.1% (n=47) considered it effective in improving the management of sessions for the next semester, and 51.4% (n=36) said it had a high impact on improving the educational content of subsequent sessions. Finally, 61.4% (n=43) students expressed high and very high levels of satisfaction with using an online survey at each session. Conclusion: The use of online surveys may be appropriate to improve lesson plans and educational planning at different levels. This method can be used for other evaluations and for assessing people’s opinions at different levels of an educational system. PMID:28491839

    Innovations in contact lens materials and designs allow patients to wear contact lenses during sleep to flatten the cornea and temporarily to reduce myopic refractive error and improve unaided visual acuity. We conducted the Children's Overnight Orthokeratology Investigation (COOKI) pilot study, a case series, to describe the refractive error and visual changes, as well as the slitlamp observations associated with overnight orthokeratology in children, over a period of 6 months. Twenty-nine 8- to 11-year-old children with myopia between -0.75 and -5.00 D and <-1.50 D corneal toricity were fitted with corneal refractive therapy contact lenses (Paragon Vision Sciences, Mesa, AZ). They were examined within 1 hour of awakening and about 6 hours later at 1 day, 1 week, 2 weeks, 1 month, 3 months, and 6 months after the first night of contact lens wear. At each visit, the logarithm of the minimum angle of resolution (logMAR) visual acuity, manifest refraction, slitlamp examination, and corneal topography were performed. Twenty-three subjects completed the 6-month study. Three subjects decided not to wear contact lenses, two did not achieve acceptable fits, and one moved from the area. At the 6-month afternoon visit, the mean +/- SD uncorrected high-contrast visual acuity was +0.08 +/- 0.15 logMAR (Snellen equivalent, 20/24), and the mean +/- SD spherical equivalent refraction was -0.16 +/- 0.66 D. The corneas of three-fifths of the subjects showed mild staining at the morning visit, and one-third of the patients showed mild corneal staining at the afternoon visit. The most common type of stain was central punctate staining. No subjects experienced lasting adverse visual effects from cornea-reshaping contact lens wear during the study period. Overnight cornea-reshaping contact lenses are efficacious for young myopic patients, and no children experienced a serious adverse event during the study.

  7. Why are medical and health-related studies not being published? A systematic review of reasons given by investigators.

    Full Text Available About half of medical and health-related studies are not published. We conducted a systematic review of reports on reasons given by investigators for not publishing their studies in peer-reviewed journals.MEDLINE, EMBASE, PsycINFO, and SCOPUS (until 13/09/2013, and references of identified articles were searched to identify reports of surveys that provided data on reasons given by investigators for not publishing studies. The proportion of non-submission and reasons for non-publication was calculated using the number of unpublished studies as the denominator. Because of heterogeneity across studies, quantitative pooling was not conducted. Exploratory subgroup analyses were conducted.We included 54 survey reports. Data from 38 included reports were available to estimate proportions of at least one reason given for not publishing studies. The proportion of non-submission among unpublished studies ranged from 55% to 100%, with a median of 85%. The reasons given by investigators for not publishing their studies included: lack of time or low priority (median 33%, studies being incomplete (median 15%, study not for publication (median 14%, manuscript in preparation or under review (median 12%, unimportant or negative result (median 12%, poor study quality or design (median 11%, fear of rejection (median 12%, rejection by journals (median 6%, author or co-author problems (median 10%, and sponsor or funder problems (median 9%. In general, the frequency of reasons given for non-publication was not associated with the source of unpublished studies, study design, or time when a survey was conducted.Non-submission of studies for publication remains the main cause of non-publication of studies. Measures to reduce non-publication of studies and alternative models of research dissemination need to be developed to address the main reasons given by investigators for not publishing their studies, such as lack of time or low priority and fear of being rejected by

    Full Text Available A polygraph is an instrument that measures and records physiological changes inside the body. In the absence of a valid physical evidence, polygraphy may be a useful technique to verify truthfulness or detect deception. The present study was conducted to determine the truthfulness of a suspect in a murder case that was referred to PFSA for a polygraph examination. The stomach contents of the examinee and the hyoid bone of the vicvtim were submitted to the department of toxicology and forensic pathology at the PFSA, respectively. In the present study, integrated zone comparison technique (IZCT and forensic assessment interview technique (FAINT designed for specific and multi issue testing were used to examine the suspect. Computerized Academy for Scientific Investigative training (ASIT Algorithm and weighted scoring were applied in IZCT and FAINT scoring, respectively. The suspect of this murder case was brought to PFSA for polygraph examination. During the initial interview, the suspect denied any involvement in the said case. However, after complete polygraph examination, the suspect was proven to have been deceptive and later on confessed to police officials. The polygraph examination of the suspect proved him deceptive which was later confirmed by his confession. His stomach did not contain any toxic/ sedative material.

    Lucas, Ray A.; Rohde, David; Tamura, Takayuki; van Dyne, Jeffrey

    At the first NVO Summer School in September 2004, a complete sample of Texas Radio Survey sources, first derived in 1989 and subsequently observed with the VLA in A-array snapshot mode in 1990, was revisited. The original investigators had never had the occasion to reduce the A-array 5-minute snapshot data, nor to do any other significant follow-up, though the sample still seemed a possibly useful but relatively small study of radio galaxies, AGN, quasars, extragalactic sources, and galaxy clusters, etc. At the time of the original sample definition in late 1989, the best optical material available for the region was the SRC-J plate from the UK Schmidt Telescope in Australia. In much more recent times, the Sloan Digital Sky Survey has included the region in its DR2 data release, so good multicolor optical imaging in a number of standard bandpasses has finally become available. These data, along with other material in the radio, infrared, and (where available) were used to get a better preliminary idea of the nature of the objects in the 1989 sample. We also investigated one of the original questions: whether these radio sources with steeper (or at least non-flat) radio spectra were associated with galaxy clusters, and in some cases higher-redshift galaxy clusters and AGN. A rudimentary web service was created which allowed the user to perform simple cone searches and SIAP image extractions of specified field sizes for multiwavelength data across the electromagnetic spectrum, and a prototype web page was set up which would display the resulting images in wavelength order across the page for sources in the sample. Finally, as an additional investigation, using radio and X-ray IDs as a proxy for AGN which might be associated with large, central cluster galaxies, positional matches of radio and X-ray sources from two much larger catalogs were done using the tool TOPCAT in order to search for the degree of correlation between ID positions, radio luminosity, and cluster

    Full Text Available The use of small UAV (Unmanned Aerial Vehicle and Structure-from-Motion (SfM with Multi-View Stereopsis (MVS for acquiring survey datasets is now commonplace, however, aspects of the SfM-MVS workflow require further validation. This work aims to provide guidance for scientists seeking to adopt this aerial survey method by investigating aerial survey data quality in relation to the application of ground control points (GCPs at a site of undulating topography (Ennerdale, Lake District, UK. Sixteen digital surface models (DSMs were produced from a UAV survey using a varying number of GCPs (3-101. These DSMs were compared to 530 dGPS spot heights to calculate vertical error. All DSMs produced reasonable surface reconstructions (vertical root-mean-square-error (RMSE of <0.2 m, however, an improvement in DSM quality was found where four or more GCPs (up to 101 GCPs were applied, with errors falling to within the suggested point quality range of the survey equipment used for GCP acquisition (e.g., vertical RMSE of <0.09 m. The influence of a poor GCP distribution was also investigated by producing a DSM using an evenly distributed network of GCPs, and comparing it to a DSM produced using a clustered network of GCPs. The results accord with existing findings, where vertical error was found to increase with distance from the GCP cluster. Specifically vertical error and distance to the nearest GCP followed a strong polynomial trend (R2 = 0.792. These findings contribute to our understanding of the sources of error when conducting a UAV-SfM survey and provide guidance on the collection of GCPs. Evidence-driven UAV-SfM survey designs are essential for practitioners seeking reproducible, high quality topographic datasets for detecting surface change.

    General environmental attitudes are often measured with questions added to surveys about specific environmental or non-environmental issues. Using results from a large-scale national survey on the protection of threatened and endangered marine species, we examine whether the context of the survey in which New Ecological Paradigm (NEP) Scale items are asked influence measured environmental concern. In this application the role that specific threatened or endangered species play in affecting responses to NEP Scale items is explored using a combination of non-parametric and parametric approaches. The results in this case suggest that context does influence stated general environmental attitudes, though the effects of context differ across NEP items. Copyright © 2013 Elsevier Inc.

    Flooding is assessed as the most important natural hazard in Europe, causing thousands of deaths, affecting millions of people and accounting for large economic losses in the past decade. Little is known about the damage processes associated with extreme rainfall in cities, due to a lack of accurate, comparable and consistent damage data. The objective of this study is to investigate the impacts of extreme rainfall on residential buildings and how affected households coped with these impacts in terms of precautionary and emergency actions. Analyses are based on a unique dataset of damage characteristics and a wide range of potential damage explaining variables at the household level, collected through computer-aided telephone interviews (CATI) and an online survey. Exploratory data analyses based on a total of 859 completed questionnaires in the cities of Münster (Germany) and Amsterdam (the Netherlands) revealed that the uptake of emergency measures is related to characteristics of the hazardous event. In case of high water levels, more efforts are made to reduce damage, while emergency response that aims to prevent damage is less likely to be effective. The difference in magnitude of the events in Münster and Amsterdam, in terms of rainfall intensity and water depth, is probably also the most important cause for the differences between the cities in terms of the suffered financial losses. Factors that significantly contributed to damage in at least one of the case studies are water contamination, the presence of a basement in the building and people's awareness of the upcoming event. Moreover, this study confirms conclusions by previous studies that people's experience with damaging events positively correlates with precautionary behaviour. For improving future damage data acquisition, we recommend the inclusion of cell phones in a CATI survey to avoid biased sampling towards certain age groups.

  15. Simple neck pain questions used in surveys, evaluated in relation to health outcomes: a cohort study

    2012-10-01

    Full Text Available Abstract Background The high prevalence of pain reported in many epidemiological studies, and the degree to which this prevalence reflects severe pain is under discussion in the literature. The aim of the present study was to evaluate use of the simple neck pain questions commonly included in large epidemiological survey studies with respect to aspects of health. We investigated if and how an increase in number of days with pain is associated with reduction in health outcomes. Methods A cohort of university students (baseline age 19–25 years were recruited in 2002 and followed annually for 4 years. The baseline response rate was 69% which resulted in 1200 respondents (627 women, 573 men. Participants were asked about present and past pain and perceptions of their general health, sleep disturbance, stress and energy levels, and general performance. The data were analyzed using a mixed model for repeated measurements and a random intercept logistic model. Results When reporting present pain, participants also reported lower prevalence of very good health, higher stress and sleep disturbance scores and lower energy score. Among those with current neck pain, additional questions characterizing the pain such as duration (categorized, additional pain sites and decreased general performance were associated with lower probability of very good health and higher amounts of sleep disturbance. Knowing about the presence or not of pain explains more of the variation in health between individuals, than within individuals. Conclusion This study of young university students has demonstrated that simple neck pain survey questions capture features of pain that affect aspects of health such as perceived general health, sleep disturbance, mood in terms of stress and energy. Simple pain questions are more useful for group descriptions than for describing or following pain in an individual.

  17. Investigating near-glacier circulation and plume theory with high-resolution fjord surveys in West Greenland

    The plumes that emanate from Greenland's glaciers are hotspots of mixing between meltwater and ambient fjord waters. The dynamics of these plumes affect both submarine melting of glacier termini and the dilution of freshwater as it is exported into the ocean. Modeling studies often rely on buoyant plume theory to represent the circulation and mixing at the ocean/ice interface. However, a dearth of measurements in the near-glacier region has left open many questions about glacial plumes, entrainment, and the applicability of idealized plume theory to these environments. Here, we present near-glacier ocean surveys from Kangerdlugssuaq Sermerssua in central West Greenland in three consecutive summers (2013-2015). High-resolution measurements of velocity and water properties were collected by ship, by surface drifters, and by a remotely operated surface vessel - all focusing on the region within 2 km of the glacier terminus. These novel measurements of the 3D circulation capture a persistent near-surface plume, along with its time-evolution over a tidal cycle and between different summers. Concurrent multibeam sonar measurements of the submarine terminus morphology show that the plume emerges from a large undercut subglacial channel outlet. Plume theory, when applied with this fjord's stratification and any flux of subglacial discharge, cannot match the observed plume's volume flux and water properties. The discrepancy between our observations and plume theory suggests that there is enhanced entrainment at depth that is not adequately represented in plume theory. The details of this entrainment have important consequences for submarine melt rates, terminus morphology, and fjord circulation.

    1989-01-01

    This volume continues the annual series of U.S. Geological Survey (USGS) reports on geologic investigations in Alaska. Since 1975, when the first of these collections of short papers appeared under the title "The United States Geological Survey in Alaska: Accomplishments during 1975," the series has been published as USGS circulars. This bulletin departs from the circular style, in part to provide a more flexible format for longer reports with more depth of content, better documentation, and broader scope than is possible for circular articles.The 13 papers in this bulletin represent a sampling of research activities carried out in Alaska by the USGS over the past few years. The topics addressed range from mineral resource studies (including natural gas) and geochemistry, Quaternary geology, basic stratigraphic and structural problems, and the use of computer graphics in geologic map preparation, to the application of geochronology to regional tectonic problems. Geographic areas represented are numbered on figure 1 and include the North Slope (1) and Brooks Range (2, 3) of Arctic Alaska, Seward Peninsula (4), interior Alaska (5-9), and remote locations of the Alaska Peninsula (10, 11) and southeast Alaska (12, 13).Two bibliographies following the reports of investigations list (1) reports about Alaska in USGS publications released in 1988 and (2) reports about Alaska by USGS authors in publications outside the USGS in 1988. A bibliography and index of the short papers in past USGS circulars devoted to Geological Research and Accomplishments in Alaska (1975-1986) is published as USGS Open-File Report 87-420.

    2007-04-01

    A number of currently proposed helmet-mounted display (HMD) designs relocate image intensification (I2) tubes to the sides of the helmet. Such a design approach induces a visual condition referred to as hyperstereo vision (or hyperstereopsis). This condition manifests itself to the user as an exaggerated sense of depth perception, causing near- to mid-range objects to appear closer than they actually are. Hyperstereopsis is potentially a major concern for helicopter operations that are conducted at low altitudes. As part of a limited flight study to investigate this phenomenon, five rated U.S. Army aviators, as technical observers, wore a hyperstereo HMD during the conduct of a series if 13 standard maneuvers. Two subject aviators acquired a total of eight hours and three aviators a single hour of flight. Using a post-flight questionnaire, these aviators were asked to compare their visual experiences to that of normal I2-aided flight. Depth perception at distances below 300 feet was identified as the greatest challenge. The two 8-hour aviators reported a 5-8 hour "adaptation" period for most maneuvers.

  20. Employing a New, BVIc Photometric Survey of IC 4665 to Investigate the Age of This Young Open Cluster

    Science.gov (United States)

    Cargile, P. A.; James, D. J.

    2010-09-01

    We present a new, BVI c photometric survey of the young open cluster IC 4665, which improves on previous studies of this young cluster by incorporating a rigorous standardization procedure, thus providing high-fidelity colors and magnitudes for cluster members. We use this new photometric dataset to reevaluate the properties (age and distance) of IC 4665. Namely, using a statistical approach incorporating τ2 color-magnitude diagram modeling, we measure a pre-main-sequence (PMS) isochrone age and distance of 36 ± 9 Myr and 360 ± 12 pc, as well as an upper-main-sequence turn-off age and distance of 42 ± 12 Myr and 357 ± 12 pc. These ages and distances are highly dependent on the isochrone model and color used for the fitting procedure, with a possible range of ~10-20 Myr in age and ~20 pc in distance. This spread in calculated ages and distances seen between colors and models is likely due to limitations in the individual membership catalogs and/or systematic differences in the predicted stellar parameters from the different sets of models. Interestingly, when we compare the isochrone ages for IC 4665 to the published lithium depletion boundary (LDB) age, 28 ± 5 Myr, we observe that this cluster does not appear to follow the trend of isochrone ages being 1.5 times smaller than LDB ages. In addition, comparing the overall magnetic activity (X-ray and Hα emission) in IC 4665 with other well-studied open clusters, we find that the observed activity distributions for this young cluster are best characterized by assuming an age of 30-40 Myr, thus in agreement with our PMS and turn-off isochrone ages for IC 4665. Overall, although some age discrepancies do exist, particularly in the ages measured from PMS isochrones, the range of possible IC 4665 ages derived from the various dating techniques employed here is relatively small compared to that found for other well-studied open clusters.

    This article is a comparative analysis of the European Values Study (EVS) and the European Social Survey (ESS) using five analytical dimensions: agents, ideas, methods, institutions and context. From the outset, both surveys were closely connected to national and European social science...... institutions, had ties to the EU, and used survey techniques to address urgent contemporary political and social problems. Despite their similarities, the surveys represent two rather different constellations of social science knowledge production. The EVS emerged from a coalition of Catholic-oriented agents...... from a diverse set of social institutions driven by political and ethical concerns about social change in the 1960s and 1970s. The EVS used its links to various social institutions to set up and run the survey, and its ethical and political concerns and connections to Catholic Church organisations...

    2002-06-01

    Full Text Available The detection of illegal buried waste by means of geophysical techniques has recently become a major effort in shallow geophysical investigations. In particular, detection and location of underground metallic storage tanks can be accomplished using different instruments and techniques. In this paper we describe the results of an investigation carried out in a tuff quarry in Riano Flaminio (north Rome, Italy. A preliminary magnetometric survey revealed the existence of anomalous zones in the analysed region. Excavation in some of the selected areas confirmed that the anomalies were generated by underground magnetic material: over 160 steel drums were found. After their removal, a new magnetometric survey was performed. On the basis of the new map, a multifrequency induction survey, a geoelectrical profile and GPR measurements were taken to extend the characterization of the subsoil.

    Takagi, Yasushi; Miyamoto, Susumu

    2015-01-01

    Moyamoya disease is a cerebrovascular occlusive disease characterized by progressive stenosis or by occlusion at the terminal portion of the bilateral internal carotid arteries. The unusual vascular network (moyamoya vessels) at the base of the brain with this disease as collateral channels is developed in this disease. Social independence because of cognitive impairment has recently been recognized as an important unsolved social issue with adult moyamoya disease. The patients with cognitive impairment have difficulty in proving their status because the standard neuroradiological and neuropsychological methods to define cognitive impairment with moyamoya disease are not determined. These patients with cognitive impairment should be supported by social welfare as psychologically handicapped persons. Thus Cognitive Dysfunction Survey of the Japanese Patients with Moyamoya Disease (COSMO-JAPAN study) is planned. In this study, we want to establish a standard finding of the cognitive impairment in patients with moyamoya disease.

  11. INTEGRATED SURVEY FOR ARCHITECTURAL RESTORATION: A METHODOLOGICAL COMPARISON OF TWO CASE STUDIES

    Directory of Open Access Journals (Sweden)

    2016-06-01

    Full Text Available A preliminary survey campaign is essential in projects of restoration, urban renewal, rebuilding or promotion of architectural heritage. Today several survey techniques allow full 3D object restitution and modelling that provides a richer description than simple 2D representations. However, the amount of data to collect increases dramatically and a trade-off between efficiency and productivity from one side and assuring accuracy and completeness of the results on the other must be found. Depending on the extent and the complexity of the task, a single technique or a combination of several ones might be employed. Especially when documentation at different scales and with different levels of detail are foreseen, the latter will likely be necessary. The paper describes two architectural surveys in Italy: the old village of Navelli (AQ, affected by the earthquake in 2009, and the two most relevant remains in Codiponte (MS, damaged by the earthquake in 2013, both in the context of a project of restoration and conservation. In both sites, a 3D survey was necessary to represent effectively the objects. An integrated survey campaign was performed in both cases, which consists of a GPS network as support for georeferencing, an aerial survey and a field survey made by laser scanner and close range photogrammetry. The two case studies, thanks to their peculiarities, can be taken as exemplar to wonder if the integration of different surveying techniques is today still mandatory or, considering the technical advances of each technology, it is in fact just optional.

  19. Participant dropout as a function of survey length in internet-mediated university studies: implications for study design and voluntary participation in psychological research.

    Science.gov (United States)

    Hoerger, Michael

    2010-12-01

    Internet-mediated research has offered substantial advantages over traditional laboratory-based research in terms of efficiently and affordably allowing for the recruitment of large samples of participants for psychology studies. Core technical, ethical, and methodological issues have been addressed in recent years, but the important issue of participant dropout has received surprisingly little attention. Specifically, web-based psychology studies often involve undergraduates completing lengthy and time-consuming batteries of online personality questionnaires, but no known published studies to date have closely examined the natural course of participant dropout during attempted completion of these studies. The present investigation examined participant dropout among 1,963 undergraduates completing one of six web-based survey studies relatively representative of those conducted in university settings. Results indicated that 10% of participants could be expected to drop out of these studies nearly instantaneously, with an additional 2% dropping out per 100 survey items included in the study. For individual project investigators, these findings hold ramifications for study design considerations, such as conducting a priori power analyses. The present results also have broader ethical implications for understanding and improving voluntary participation in research involving human subjects. Nonetheless, the generalizability of these conclusions may be limited to studies involving similar design or survey content.

    Environmental restoration involves the cleanup and restoration of US Department of Energy (DOE) sites and facilities contaminated with hazardous substances during past production or disposal activities. An important element of the environmental restoration process is the remedial investigation and feasibility study (RI/FS), which is designed to determine the extent of contamination and to identify alternatives for cleanup. The Office of the Assistant Secretary for Environmental Restoration and Waste Management is responsible for policy direction and oversight of DOE`s environmental restoration program. The objective of the audit was to determine whether DOE and its contractors had developed effective management control systems to ensure that maximum benefits were obtained from the funds spent on the RI/FS at the Fernald Environmental Management Project. Although DOE had improved the Fernald RI/FS project over the previous 18 months, the project at Fernald was not planned and controlled cost effectively. This condition occurred because (1) DOE and its contractors lacked experience in the RI/FS process, (2) DOE and its contractors had not communicated effectively with one another and outside regulators, and (3) DOE had not placed enough emphasis on management control systems. As a result, after about 6 years and the expenditure of over $100 million on the RI/FS project at Fernald, DOE and the Environmental Protection Agency (EPA) had made no decisions as to future land use, cleanup methods, disposal sites, or the level of environmental protection needed for the site. For each year that the completion of the RI/FS and cleanup is unnecessarily delayed, DOE will be required to spend about $149 million to support site infrastructure costs. Finally, DOE was planning for the possible construction of waste storage buildings, estimated to cost $2.6 billion, when the need for the buildings had not been validated .

  2. A gender study investigating physics self-efficacy

    Sawtelle, Vashti

    The underrepresentation of women in physics has been well documented and a source of concern for both policy makers and educators. My dissertation focuses on understanding the role self-efficacy plays in retaining students, particularly women, in introductory physics. I use an explanatory mixed methods approach to first investigate quantitatively the influence of self-efficacy in predicting success and then to qualitatively explore the development of self-efficacy. In the initial quantitative studies, I explore the utility of self-efficacy in predicting the success of introductory physics students, both women and men. Results indicate that self-efficacy is a significant predictor of success for all students. I then disaggregate the data to examine how self-efficacy develops differently for women and men in the introductory physics course. Results show women rely on different sources of self-efficacy than do men, and that a particular instructional environment, Modeling Instruction, has a positive impact on these sources of self-efficacy. In the qualitative phase of the project, this dissertation focuses on the development of self-efficacy. Using the qualitative tool of microanalysis, I introduce a methodology for understanding how self-efficacy develops moment-by-moment using the lens of self-efficacy opportunities. I then use the characterizations of self-efficacy opportunities to focus on a particular course environment and to identify and describe a mechanism by which Modeling Instruction impacts student self-efficacy. Results indicate that the emphasizing the development and deployment of models affords opportunities to impact self-efficacy. The findings of this dissertation indicate that introducing key elements into the classroom, such as cooperative group work, model development and deployment, and interaction with the instructor, create a mechanism by which instructors can impact the self-efficacy of their students. Results from this study indicate that

    2010-05-01

    Full Text Available Abstract Background A considerable literature now supports the importance of effective communication with study participants, including how best to develop communication plans focusing on the uncertainty of health risks associated with particular environmental exposures. Strategies for communicating individual concentrations of environmental chemicals in human biological samples in the absence of clearly established safe or hazardous levels have been discussed from a conceptual basis and to a lesser extent from an empirical basis. We designed and evaluated an empirically based communication strategy for women of reproductive age who previously participated in a prospective study focusing on persistent environmental chemicals and reproductive outcomes. Methods A cohort of women followed from preconception through pregnancy or up to 12 menstrual cycles without pregnancy was given their individual serum concentrations for lead, dichloro-2,2-bisp-chlorophenyl ethylene, and select polychlorinated biphenyl congeners. Two versions of standardized letters were prepared depending upon women's exposure status, which was characterized as low or high. Letters included an introduction, individual concentrations, population reference values and guidance for minimizing future exposures. Participants were actively monitored for any questions or concerns following receipt of letters. Results Ninety-eight women were sent letters informing them of their individual concentrations to select study chemicals. None of the 89 (91% participating women irrespective of exposure status contacted the research team with questions or concerns about communicated exposures despite an invitation to do so. Conclusions Our findings suggest that study participants can be informed about their individual serum concentrations without generating unnecessary concern.

    2009-06-01

    Full Text Available It is recommended that researchers who use mixed modal methods for data collection compare their impact on outcome measures. The purpose of this study was to examine the physical activity and fruit/vegetable consumption behaviors of a multiethnic sample of adults, comparing participants who continued a telephone survey and those who transitioned from a telephone to a web-based survey for a follow-up data collection point. This longitudinal study used a random sample of 700 Hawaii residents (63.3% Female; Mean age=47, SD=17.1. At baseline, participants completed a computer-assisted telephone interview assessing the stage, behavior, and decisional balance of both physical activity and fruit/vegetable consumption. For the three-month follow-up survey, participants were given the option of completing the survey either on the web or by phone. Repeated measures analysis of variance (ANOVA was computed for related physical activity scales and fruit/vegetable consumption variables to compare the change in response across time between a web group and phone group. For both physical activity and fruit/vegetable consumption, all mode-by-time interactions were significant. The participants who preferred the telephone survey maintained their levels, whereas those who preferred the web survey reported a decrease in each variable. These results suggest that changing the mode of a survey may introduce a systematic bias in data and that researchers should proceed with caution when using mixed modes of data collection.

    Full Text Available BACKGROUND: Human papillomavirus (HPV has been observed repeatedly in esophageal squamous cell carcinoma (ESCC tissues. However, the causal relationship between HPV infection and the onset of ESCC remains unknown. A large cohort study focusing on this topic is being carried out in rural Anyang, China. METHODOLOGY/PRINCIPAL FINDINGS: The Anyang Esophageal Cancer Cohort Study (AECCS is a population-based prospective endoscopic cohort study designed to investigate the association of HPV infection and ESCC. This paper provides information regarding the design and implementation of this study. In particular we describe the recruitment strategies and quality control procedures which have been put into place, and the custom designed computer-aided survey system (CASS used for this project. This system integrates barcode technology and unique identification numbers, and has been developed to facilitate real-time data management throughout the workflow using a wireless local area network. A total of 8,112 (75.3% of invited subjects participated in the baseline endoscopic examination; of those invited two years later to take part in the first cycle of follow-up, 91.9% have complied. CONCLUSIONS/SIGNIFICANCE: The AECCS study has high potential for evaluating the causal relationship between HPV infection and the occurrence of ESCC. The experience in setting up the AECCS may be beneficial for others planning to initiate similar epidemiological studies in developing countries.

    Full Text Available This paper performs an investigation on measuring the effect of different factors on customer relationship management (CRM for different branches of an Iranian banks located in various regions of city of Tehran, Iran. The proposed study selects a sample of 275 managers and using structural equation modeling examines the effects of five variables including CRM knowledge, employment’s information technology skills, specialty, strategic use, CRM performance on the performance of CRM. Cronbach alpha has been calculated for the questionnaire as 0.881, which is well above the minimum acceptable level. The survey has concluded that there were meaningful relationships between all four mentioned variables and performance of CRM. In other words, knowledge and information technology influence on improving employments’ skills, which increase strategic use of CRM components and this would improve CRM performance.

    Previous research has indicated a disconnect between academic nursing programmes and workplace learning environments. Nurse supervisors and clinical practitioners have reported inadequate information and training on how to support students of nursing to learn in the clinical setting. This study aimed to investigate the level of confidence that clinical supervisors have in relation to specific components of supporting student learning in the work place. Survey of clinical nurse supervisors. Simulation-based clinical reasoning workshops. Sixty participants: fifty nine registered nurses, including nurse managers and clinical nurse educators, and one allied health professional. Survey using Likert scales and free-text questions. The findings indicated that clinicians were confident in sharing their knowledge and experience with students and making them feel welcome in the work place, they were less confident about what were the significant learnings in relation to students' academic programme. Registered nurses supervising students were experienced clinicians with many role responsibilities, which were perceived as barriers to the role of clinical supervisor. Participants reported that they would like tools to assist them with developing links to the academic programme. They considered that these tools would support student learning and remediation in the work place. This study found that the abilities of supervisors to support student learning is an identified gap impacting on work integrated learning. The results indicated the need for a professional development workshop, to enable clinical supervisors to move beyond promoting a supervision model, towards a theoretical framework for assisting and guiding students to learn. Addressing this deficit will improve growth and change in student learning in the work place. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Magnetic resonance imaging (MRI) modalities have emerged as powerful means that facilitate non-invasive clinical diagnostics of various diseases and abnormalities since their inception in the 1980s. Multiple MRI modalities, such as different types of the sMRI and DTI, have been employed to investigate facets of ASD in order to better understand this complex syndrome. This paper reviews recent applications of structural magnetic resonance imaging (sMRI) and diffusion tensor imaging (DTI), to study autism spectrum disorder (ASD). Main reported findings are sometimes contradictory due to different age ranges, hardware protocols, population types, numbers of participants, and image analysis parameters. The primary anatomical structures, such as amygdalae, cerebrum, and cerebellum, associated with clinical-pathological correlates of ASD are highlighted through successive life stages, from infancy to adulthood. This survey demonstrates the absence of consistent pathology in the brains of autistic children and lack of research investigations in patients under 2 years of age in the literature. The known publications also emphasize advances in data acquisition and analysis, as well as significance of multimodal approaches that combine resting-state, task-evoked, and sMRI measures. Initial results obtained with the sMRI and DTI show good promise toward the early and non-invasive ASD diagnostics. PMID:27242476

    The longitudinal epidemiological population study NEMESIS-2 (Netherlands Mental Health Survey and Incidence Study-2) replicates the first study conducted from 1996 to 1999, and expands it by adding new subjects such as impulse-control disorders. To describe the aims and design of nemesis-2, particularly of its first round of measurements, to provide up-to-date figures on prevalence, incidence, course and consequences of mental disorders and associated factors, and to study trends in the mental health of the population aged 18-64 years and the use these people make of psychiatric services. Face-to-face interviews were conducted (November 2007-July 2009) by means of the Composite International Diagnostic Interview 3.0. The response was 65.1% (n = 6646). Respondents were reasonably representative for the population, but young persons were somewhat underrepresented. Two follow-up rounds of measurements are planned with three-year intervals between the rounds. The second round of measurements began in November 2010. A qualitatively good dataset was built up. This will allow several mental health topics to be studied in the future.

    Objective Although many surgical patients face postoperative problems due to a poor nutritional status, there is evidence that many cases of malnutrition still go unnoticed and untreated in surgical wards. This study aims to define the current attitudes of surgeons toward nutritional screening and support. Material and Methods A questionnaire with 13 questions was e-mailed to 1500 surgeons. Cross-queries were made over the responses. Results The response rate was 20.9%. Most of the respondents (89.5%) implemented nutritional screening. However, only 24.6% of these surgeons screened every patient for malnutrition. The time to initiate nutritional support varied among respondents, and only 25.5% started nutritional support early enough prior to surgery. Only 9.9% of respondents implemented evidence based practices for preoperative fasting, and 21.2% preferred immunonutrition products for patients undergoing major abdominal surgery for cancer. The responses of surgeons, who participated in at least one scientific meeting on nutrition per year, were more coherent with the nutrition guidelines. Conclusions The results of this study reveal that the awareness and knowledge of clinical nutrition need improving amongst surgeons. To increase this awareness and knowledge, continuous learning throughout their career seems essential. PMID:28944324

Only 9.9% of respondents implemented evidence based practices for preoperative fasting, and 21.2% preferred immunonutrition products for patients undergoing major abdominal surgery for cancer. The responses of surgeons, who participated in at least one scientific meeting on nutrition per year, were more coherent with the nutrition guidelines. The results of this study reveal that the awareness and knowledge of clinical nutrition need improving amongst surgeons. To increase this awareness and knowledge, continuous learning throughout their career seems essential.

    Full Text Available CIGB-552 is a cell-penetrating peptide that exerts in vitro and in vivo antitumor effect on cancer cells. In the present work, the mechanism involved in such anticancer activity was studied using chemical proteomics and expression-based proteomics in culture cancer cell lines. CIGB-552 interacts with at least 55 proteins, as determined by chemical proteomics. A temporal differential proteomics based on iTRAQ quantification method was performed to identify CIGB-552 modulated proteins. The proteomic profile includes 72 differentially expressed proteins in response to CIGB-552 treatment. Proteins related to cell proliferation and apoptosis were identified by both approaches. In line with previous findings, proteomic data revealed that CIGB-552 triggers the inhibition of NF-κB signaling pathway. Furthermore, proteins related to cell invasion were differentially modulated by CIGB-552 treatment suggesting new potentialities of CIGB-552 as anticancer agent. Overall, the current study contributes to a better understanding of the antitumor action mechanism of CIGB-552.

    Full Text Available The purpose of this study was to examine differences between the results of an in person or face-to-face direct spending survey and a post-event online direct spending survey. Participants in a large annual marathon held in the Mid-Atlantic Region of the United States were used as subjects for the study. The research methodology selected for this study included an in person survey instrument administered to out-of-town marathon participants prior to the start of the event during the race number and race timing chip pick-up period. The same survey instrument was administered online four days after the conclusion of the marathon to the same group of out-of-town marathon participants who did not previously respond to the in person survey. Analysis of data and results revealed that average direct spending for the online respondents was consistently and significantly higher than spending for the in person respondents on direct spending questions. Spending on lodging for both groups showed no significant differences. It was recommended that the use of online survey methods be considered when conducting direct spending studies for participant oriented sporting events when adequate e-mail addresses are available and the potential respondents have a certain level of computer literacy.

    Full Text Available This research proposes a comprehensive model that investigates the relationships between service quality, hedonic, perceived value and behavioral intentions. The purpose of this study is to build a better understanding of the determinants of customer satisfaction and customer loyalty throughout the restaurant services by incorporating the perceptions of hedonic effect in service delivery and outlining why and how service quality is important to customer satisfaction and customer loyalty. Respondents were chosen from three regular customers of Atawich chain restaurants in city of Tehran by using stratified random sampling method. A total of 390 questionnaires were used for data analysis. Structural equations modeling by using LISREL was performed to empirically test the relationships between the constructs of this study. Results show that both service quality and hedonic effect are importance predictors of customer satisfaction in Iranian society. In addition, results indicate that service quality and hedonic effect have positive and significant effects on perceived value. However, relationship between customer satisfaction and perceived value with attitudinal loyalty was not significant. Finally, it suggests that restaurant managers should improve their restaurant service offerings to satisfy customers. In addition, the results emphasize the significance of hedonic effect and positive emotions in creating perceived value and customer satisfaction.

    Previous studies have investigated process and structure indicators of nutritional care as well as their use in nursing homes (NHs), but the relative weight of these indicators in predicting the risk of malnutrition remains unclear. Aims of the present study are to describe the quality indicators of nutritional care in older residents in a sample of NHs in Tuscany, Italy, and to evaluate the predictors of protein-energy malnutrition risk. A cross-sectional survey was conducted in 67 NHs. Information was collected to evaluate quality indicators of nutritional care and the individual risk factors for malnutrition, which was assessed using the Malnutrition Universal Screening Tool. A multilevel model was used to analyse the association between risk and predictors. Out of 2395 participants, 23.7 % were at high, 11 % at medium, and 65.3 % at low risk for malnutrition. Forty-two percent of the NHs had only a personal scale to weigh residents; 88 % did not routinely use a screening test/tool for malnutrition; 60 % used some standardized approach for weight measurement; 43 % did not assess the severity of dysphagia; 12 % were not staffed with dietitians. Patients living in NHs where a chair or platform scale was available had a significantly lower risk of malnutrition (OR = 0.73; 95 % CI = 0.56-0.94). None of the other structural or process quality indicators showed a statistically significant association with malnutrition risk. Of all the process and structural indicators considered, only the absence of an adequate scale to weigh residents predicted the risk of malnutrition, after adjusting for case mix. These findings prompt the conduction of further investigations on the effectiveness of structural and process indicators that are used to describe quality of nutritional care in NHs.

    Background According to the Digital Agenda for Europe, the way children use the Internet and mobile technologies has changed dramatically in the past years. Objective The aims of this study were to: (1) breakdown the modalities of access and use of the Internet by teenagers to assess risks and risky behaviors; and (2) provide scientific data to evaluate and counsel safe use of the Internet and new technologies by teenagers. Methods The study was conducted under the program “Strategies for a Better Internet for Children” started in May 2012 by the European Commission. It represents the main result of the project launched by Telecom Italia, “Anche io ho qualcosa da dire” (I too have something to say), thanks to which many contributions were collected and used to develop a survey. The questionnaire was structured in 45 questions, covering three macro areas of interest. It was approved by the Department Board at University of Magna Graecia’s School of Medicine. After authorization from the regional high school authority, it was administered to all 1534 students (aged 13-19 years) in the city of Catanzaro, Italy. Results The data was broken down into three main groups: (1) describing education and access to the Internet; (2) methods of use and social networking; and (3) perception and evaluation of risk and risky behaviors. Among noteworthy results in the first group, we can mention that the average age of first contact with information technologies was around 9 years. Moreover, 78.87% (1210/1534) of the interviewed students reported having access to a smartphone or a tablet. Among the results of the second group, we found that the most used social networks were Facebook (85.78%, 1316/1534), YouTube (61.14%, 938/1534), and Google+ (51.56%, 791/1534). About 71.31% (1094/1534) of the interviewed teenagers use their name and surname on social networks, and 40.09% (615/1534) of them knew all their Facebook contacts personally. Among the results of the third group

    Full Text Available As the availability of computers and the Internet in schools and classrooms has grown, so has interest in the extent to which these technologies are being used and for what purposes. Recently there has been many studies on teachers’ use of education technology in their classrooms and schools, the availability of this technology in their classrooms and schools, their training and preparation for their use and the barriers to technology use they encounter. Using the Internet effectively and the success of the Internet utilization is very much related to the users’ attitudes toward the Internet. This study aims at investigating the reliability and the validity of the Internet Use of Pre-service English Teachers Survey modified from the Master Thesis of Sudsuang Yutdhana. The survey contains two subscales as Internet Attitude Scale and Self-perception of Computing Skills. The survey was administered to randomly selected third and fourth year 96 pre – service English Teachers at Dokuz Eylül University Buca, Faculty of Education, Department of English Language Teaching. The results indicated that Internet Use of Pre-service English Teachers Survey (IUPETS is reliable and valid.

  12. An Investigation of Sustainable Power Generation from Oil Palm Biomass: A Case Study in Sarawak

    Directory of Open Access Journals (Sweden)

    Nasrin Aghamohammadi

    2016-04-01

    Full Text Available Sarawak is the largest state in Malaysia, with 22% of the nation's oil palm plantation area, making it the second largest contributor to palm biomass production. Despite the enormous amount of palm biomass in the state, the use of biomass as fuel for power generation remains low. This study is designed to investigate the sustainability of power generation from palm biomass specifically in Sarawak by conducting a survey among the palm oil mill developers. To conduct this investigation, several key sustainability factors were identified: the security of the biomass supply, the efficiency of conversion technology, the existing network system, challenges and future prospects for power generation from palm biomass. These factors were assessed through a set of questionnaires. The returned questionnaires were then analysed using statistical tools. The results of this study demonstrate that Sarawak has biomass in abundance, and that it is ready to be exploited for large scale power generation. The key challenge to achieving the renewable energy target is the inadequate grid infrastructure that inhibits palm oil developers from benefiting from the Feed-in-Tariff payment scheme. One way forward, a strategic partnership between government and industrial players, offers a promising outcome, depending on an economic feasibility study. The decentralization of electricity generation to support rural electrification is another feasible alternative for renewable energy development in the state.

    Full Text Available This paper presents an empirical investigation to study the relationship between employee performance and TQM. The proposed study of this paper designs two questionnaires for TQM and performance measurement and distributes them among some employees who worked for one of Iranian banks in city of Semnan, Iran. The result of Kolmogorov–Smirnov test confirms that all data are normally distributed and the study uses Pearson correlation to investigate the relationship between various components of the survey. The result of the implementation of Pearson correlation ratio indicates that there was a positive and meaningful relationship between employee performance and TQM components (r=4.6223, P-value=0.000. In addition, there are some positive and meaningful relationships between TQM components and employee performance. The highest correlation belongs to relationship between employee performance and feedback (r=4.6223, P-value=0.000 followed by training and development (r = 0.441, P-value = 0.000 and communication (r = 4.2861, P-value = 0.000.

  14. Learning lessons from field surveys in humanitarian contexts: a case study of field surveys conducted in North Kivu, DRC 2006-2008

    2009-09-01

    Full Text Available Abstract Survey estimates of mortality and malnutrition are commonly used to guide humanitarian decision-making. Currently, different methods of conducting field surveys are the subject of debate among epidemiologists. Beyond the technical arguments, decision makers may find it difficult to conceptualize what the estimates actually mean. For instance, what makes this particular situation an emergency? And how should the operational response be adapted accordingly. This brings into question not only the quality of the survey methodology, but also the difficulties epidemiologists face in interpreting results and selecting the most important information to guide operations. As a case study, we reviewed mortality and nutritional surveys conducted in North Kivu, Democratic Republic of Congo (DRC published from January 2006 to January 2009. We performed a PubMed/Medline search for published articles and scanned publicly available humanitarian databases and clearinghouses for grey literature. To evaluate the surveys, we developed minimum reporting criteria based on available guidelines and selected peer-review articles. We identified 38 reports through our search strategy; three surveys met our inclusion criteria. The surveys varied in methodological quality. Reporting against minimum criteria was generally good, but presentation of ethical procedures, raw data and survey limitations were missed in all surveys. All surveys also failed to consider contextual factors important for data interpretation. From this review, we conclude that mechanisms to ensure sound survey design and conduct must be implemented by operational organisations to improve data quality and reporting. Training in data interpretation would also be useful. Novel survey methods should be trialled and prospective data gathering (surveillance employed wherever feasible.

    This online survey of practising radiation oncologists from Korea, China and Japan was conducted to investigate the current practices in radiotherapy (RT) for spine metastasis and to compare these practices across the three countries. The questionnaire included nine general information questions and two clinical scenarios (representing 'typical' and 'good' prognosis spine metastasis), with seven questions for each scenario. An anonymous web-based survey using Google Docs® was undertaken from 2 September 2014 to 9 April 2015. A total of 54 Korean, 107 Chinese and 104 Japanese radiation oncologists participated in the study. The first scenario involved a typical case of spine metastasis (~25% expected 1-year survival rate), and the preferred fractionation scheme was 10 fractions of 3 Gy, though the pattern was slightly different in each country. The second scenario involved a good prognosis case (>50% expected 1-year survival rate), and 10 fractions of 3 Gy was the preferred practice in all three countries (however, use of a larger fraction dose with a smaller fraction number was more common in Korea). A more conformal RT technique was more prominent in China and Korea, especially for patients with a good prognosis. Avoidance of reirradiation was notable in China. In summary, a preference for multiple fractionation in RT for spine metastasis was observed in the majority of Korean, Chinese and Japanese radiation oncologists, although there were slight differences in practice preferences, especially for patients with a favorable prognosis. © The Author 2016.

    While guidance exists for obtaining population size estimates using multiplier methods with respondent-driven sampling surveys, we lack specific guidance for making sample size decisions. To guide the design of multiplier method population size estimation studies using respondent-driven sampling surveys to reduce the random error around the estimate obtained. The population size estimate is obtained by dividing the number of individuals receiving a service or the number of unique objects distributed (M) by the proportion of individuals in a representative survey who report receipt of the service or object (P). We have developed an approach to sample size calculation, interpreting methods to estimate the variance around estimates obtained using multiplier methods in conjunction with research into design effects and respondent-driven sampling. We describe an application to estimate the number of female sex workers in Harare, Zimbabwe. There is high variance in estimates. Random error around the size estimate reflects uncertainty from M and P, particularly when the estimate of P in the respondent-driven sampling survey is low. As expected, sample size requirements are higher when the design effect of the survey is assumed to be greater. We suggest a method for investigating the effects of sample size on the precision of a population size estimate obtained using multipler methods and respondent-driven sampling. Uncertainty in the size estimate is high, particularly when P is small, so balancing against other potential sources of bias, we advise researchers to consider longer service attendance reference periods and to distribute more unique objects, which is likely to result in a higher estimate of P in the respondent-driven sampling survey.

    This Data-in-Brief article contains a detailed method for the conduct of this survey and additional original data. In this survey, we also provided vascular surgery colleagues with contemporary epidemiologic and surgical outcome data. This was followed by a hypothetical scenario whereby a patient had just been diagnosed with a small (40 mm AAA and a novel biomarker predicted it to be fast growing in the coming years. We assessed the vascular professionals' perception of the patient's preference for management in this scenario, and their willingness to refer patients for a surgical trial that investigates the outcome of early versus late surgery in this setting. The survey then asked the vascular professionals to assume the role of the patient, and provided their own preferences in such a scenario.

    2017-06-01

    This article examines the relevance of survey data of scientists' attitudes about science and values to case studies in philosophy of science. We describe two methodological challenges confronting such case studies: 1) small samples, and 2) potential for bias in selection, emphasis, and interpretation. Examples are given to illustrate that these challenges can arise for case studies in the science and values literature. We propose that these challenges can be mitigated through an approach in which case studies and survey methods are viewed as complementary, and use data from the Toolbox Dialogue Initiative to illustrate this claim.

    2014-01-01

    General population surveys have seldom examined violence as a multidimensional concept and in relation to an array of mental disorders. Data from the South East London Community Health Study was used to examine the prevalence, overlap and distribution of proximal witnessed, victimised and perpetrated violence and their association with current mental disorders. We further investigated the cumulative effect of lifetime exposure to violence on current mental disorders. Unadjusted and adjusted (for confounders and violence) models were examined. In the last twelve months, 7.4% reported witnessing violence, 6.3% victimisation and 3.2% perpetration of violence. There was a significant overlap across violence types, with some shared correlates across the groups such as being younger and male. Witnessing violence in the past year was associated with current common mental disorders (CMD) and post-traumatic stress disorder (PTSD) symptoms. Proximal perpetration was associated with current CMD, PTSD symptoms and past 12 months drug use; whereas proximal victimisation was associated with lifetime and past 12 months drug use. Lifetime exposure to two or more types of violence was associated with increased risk for all mental health outcomes, suggesting a cumulative effect. Exposure to violence needs to be examined in a multi-faceted manner: i) as discrete distal and proximal events, which may have distinct patterns of association with mental health and ii) as a concept with different but overlapping dimensions, thus also accounting for possible cumulative effects.

  1. Investigating sources of pharmaceutical pollution: Survey of over-the-counter and prescription medication purchasing, use, and disposal practices among university students.

    Vatovec, Christine; Van Wagoner, Emily; Evans, Corey

    2017-08-01

    Pharmaceutical pollution in surface waters poses a range of risks to public health and aquatic ecosystems. Consumers contribute to pharmaceutical pollution via use and disposal of medications, though data on such behaviors is limited. This paper investigates the purchasing, use, and disposal practices among a population that has been researched only minimally to date, yet will determine pharmaceutical pollution for decades to come: young adults represented by a university student population. We employed an online, 21-question survey to examine behaviors related to pharmaceuticals among students at the University of Vermont (n = 358). Results indicate that the majority of respondents had purchased medications in the previous 12 months (94%), and had leftover drugs (61%). Contrary to previous studies of older populations, only a small proportion of students had disposed of drugs (18%); municipal trash was the primary route of drug disposal (25%), and very few students disposed drugs via flushing (1%). Less than a quarter of students were aware of drug take-back programs (24%), and only 4% had ever used take-back services. These findings indicate that the university student population may be storing a large volume of unused drugs that will require future disposal. Increasing awareness of, access to, and participation in pro-environment pharmaceutical behaviors, such as purchasing over-the-counter medication in smaller quantities and utilizing drug take-back programs, could minimize future pharmaceutical pollution from this population.

  3. Investigation of Poultry Waste for Anaerobic Digestion: A Case Study

    Science.gov (United States)

    Salam, Christopher R.

    Anaerobic Digestion (AD) is a biological conversion technology which is being used to produce bioenergy all over the world. This energy is created from biological feedstocks, and can often use waste products from various food and agricultural processors. Biogas from AD can be used as a fuel for heating or for co-generation of electricity and heat and is a renewable substitute to using fossil fuels. Nutrient recycling and waste reduction are additional benefits, creating a final product that can be used as a fertilizer in addition to energy benefits. This project was conducted to investigate the viability of three turkey production wastes as AD feedstock: two turkey litters and a material separated from the turkey processing wastewater using dissolved air flotation (DAF) process. The DAF waste contained greases, oils and other non-commodity portions of the turkey. Using a variety of different process methods, types of bacteria, loading rates and food-to-microorganism ratios, optimal loading rates for the digestion of these three materials were obtained. In addition, the co-digestion of these materials revealed additional energy benefits. In this study, batch digestion tests were carried out to treat these three feedstocks, using mesophilic and thermophilic bacteria, using loading rates of 3 and 6 gVS/L They were tested separately and also as a mixture for co-digestion. The batch reactor used in this study had total and working volumes of 1130 mL and 500 mL, respectively. The initial organic loading was set to be 3 gVS/L, and the food to microorganism ratio was either 0.6 or 1.0 for different treatments based on the characteristics of each material. Only thermophilic (50 +/- 2ºC) temperatures were tested for the litter and DAF wastes in continuous digestion, but mesophilic and thermophilic batch digestion experiments were conducted. The optimum digestion time for all experiments was 14 days. The biogas yields of top litter, mixed litter, and DAF waste under

    Lewers, Sarah Grace

    Industrial chemicals are a major part of the United States economic growth and impact every product that we use in everyday life. Some of the major products produced by chemical-related industries are plastics, textiles, petroleum, paper and important metals. Governmental regulations like those created by the Occupational Safety and Health Organization (OSHA), Environmental Protection Agency (EPA) and the U.S. Chemical Safety and Hazard Investigation Board are vital to a chemical-related industries' safety management. Contributing to and helping to drive economic growth, the enforcement of proper safety practices is a necessity. This study was conducted to investigate and assess various safety management practices in selected chemical-related industries. The research design involved the use of a questionnaire/survey method in which a random sample of participants completed a questionnaire related to the variables of interest. Random sampling helps to ensure the generalizability of the survey results. The target population consisted of a subset of employees currently working for plants, businesses and organizations in chemical-related industries. To collect the data, surveys were given to employees in various positions at chemical-related industries such as basic chemicals, specialty chemicals, agricultural chemicals, pharmaceuticals and consumer products. A set of criteria was created to establish the qualification to be recognized as a chemical-related industry. The questionnaire/survey was reviewed by the Institutional Review Board at NC A&T State University to meet necessary regulation guidelines for research involving human subjects.

    Full Text Available In the school year of 2009–2010 Vilnius Gediminas Technical University initiated the the survey of motives for studies at this university. The aim of the research is to conduct a survey among first year undergraduate students and find out motives for their choise to study at Vilnius Gediminas Technical University. Due to weaknesses of national science and studies system, devaluation of diplomas, outdated teaching methods, scien- tific research unproductivity and simulation, lack of attention to the student, ineffective study loans system, discrimination of private study institutions and their students, etc., a new Science and Study Law was initiated in 2009. Thus new challenges to the country, universities, and university communities arise. Future students are becoming more aware studying opportunities both within the country and abroad. Motives and choices of studies are determined by more complex approaches and levers. The article analyses a survey is based on responses of first year undergraduates of Vilnius Gediminas Technical University. The objective of the survey is to find out why and how students have chosen to study at this university. The purpose of the article is to identify these motives, provide analysis and assessment of survey data.

    The article addresses the application of electrical resistivity imaging for engineering site investigation in Pishva Hospital, Varamin, Iran. Some aqueduct shafts exist in the study area backfilled by loose materials. The goals of this study are to detect probable aqueduct tunnels and their depth, investigate filling quality in the shafts as well as connection(s) between them. Therefore, three profiles were surveyed by dipoledipole electrode array. Also, to investigate the potentially anomalous areas more accurately, five additional resistivity profiles were measured by a Combined Resistivity Sounding-Profiling array (CRSP). According to the results of 2-D inversion modelling, a main aqueduct tunnel was detected beneath the central part of the site. Finally, the resistivity pattern of the detected aqueduct system passing the investigated area was provided using the obtained results.

    We describe activities undertaken to conduct organizational surveys among faith-based organizations in Massachusetts as part of a larger study designed to promote parish-based cancer control programs for Latinos. Catholic parishes located in Massachusetts that provided Spanish-language mass were eligible for study participation. Parishes were identified through diocesan records and online directories. Prior to parish recruitment, we implemented a variety of activities to gain support from Catholic leaders at the diocesan level. We then recruited individual parishes to complete a four-part organizational survey, which assessed (A) parish leadership, (B) financial resources, (C) involvement in Hispanic Ministry, and (D) health and social service offerings. Our goal was to administer each survey component to a parish representatives who could best provide an organizational perspective on the content of each component (e.g., A = pastors, B = business managers, C = Hispanic Ministry leaders, and D = parish nurse or health ministry leader). Here, we present descriptive statistics on recruitment and survey administration processes. Seventy-five percent of eligible parishes responded to the survey and of these, 92% completed all four components. Completed four-part surveys required an average of 16.6 contact attempts. There were an average of 2.1 respondents per site. Pastoral staff were the most frequent respondents (79%), but they also required the most contact attempts (M = 9.3, range = 1-27). While most interviews were completed by phone (71%), one quarter were completed during in-person site visits. We achieved a high survey completion rate among organizational representatives. Our lessons learned may inform efforts to engage and survey faith-based organizations for public health efforts. © 2015 Society for Public Health Education.

  10. Experimental Study on Electrode Method for Electrical Resistivity Survey to Detect Cavities under Road Pavements

    2017-12-01

    Full Text Available There are two types of electrode methods for electrical resistivity survey (ERS: the pole electrode method (PEM and flat electrode method (FEM. During the past few decades, most studies were conducted by using PEM for various purposes while only a few were conducted by using FEM. Laboratory and field experiments were performed in this study to investigate the advantage of FEM in detecting cavities under pavements. In the laboratory experiment, the results of PEM and FEM were compared graphically and statistically. A significant difference between the results of PEM and FEM was observed for concrete at an age of seven days, while there was no significant difference in the results for soil materials. Electrical resistivity could not be obtained from asphalt because it is an insulator. In a field experiment, four different cases were simulated: field ground with/without cavity and concrete pavement with/without cavity. The results of PEM and FEM for these cases were compared using 2D electrical resistivity contour images. It was observed that the distribution of electrical resistivity obtained using FEM was wider than that using PEM. Moreover, the locations of the cavities artificially made in the ground and under the pavement were accurately detected using both PEM and FEM.

    2003-01-01

    We carried out a mission concept Study for an ultra-long duration balloon (ULDB) mission to conduct a high-sensitivity hard x-ray (approx. 20-600 keV) imaging sky survey. The EXIST-LITE concept has been developed, and critical detector technologies for realistic fabrication of very large area Cd-Zn-Te imaging detector arrays are now much better understood. A ULDB mission such as EXIST-LITE is now even more attractive as a testbed for the full Energetic X-ray Imaging Survey Telescope (EXIST) mission, recommended by the Decadal Survey, and now included in the NASA Roadmap and Strategic Plan as one of the 'Einstein Probes'. In this (overdue!) Final Report we provide a brief update for the science opportunities possible with a ULDB mission such as EXIST-LITE and relate these to upcoming missions (INTErnational Gamma-Ray Astrophysics Laboratory (INTEGRAL) and Swift) as well as the ultimate very high sensitivity sky survey mission EXIST. We then review the progress made over this investigation in Detector/Telescope design concept, Gondola and Mission design concept, and Data Handling/Analysis.

    A tobacco surveillance system is crucial for improving the planning and implementation of effective tobacco control policies. The purpose of the presented study was to describe a review of the process of implementation and methodological assumption of a Global Adult Tobacco Survey (GATS) conducted in Poland. The study strengths and limitations are evaluated, as well as some recommendations given for further tobacco surveillance activities in Poland. The Global Adult Tobacco Survey (GATS) was implemented in Poland between 2008-2010. The survey population selection process was based on a three-stage stratified geographically-clustered sample of a non-institutional population aged 15 years and over. Those who lived in institutions were not surveyed. The GATS questionnaire was very detailed and provides a significant amount of data. The filed work was preceded by several training sessions for all survey staff and the pretest. Questionnaires were administered in respondents' homes during the face-to-face interviews. Of the 14,000 households selected for the survey, 8,948 (63.9%) households and 7,840 (93.9%) sampled individuals completed the interviews. The total survey response rate was 65.1%. GATS was an important step towards obtaining representative, current data on the tobacco epidemic in Poland. Basic results of the study are currently available. More in-depth analysis will provide useful data for public health experts and policymakers to assign resources and establish health priorities. Unfortunately, competing targets and lack of awareness on the part of stakeholders still constrains the financial resources available to those undertaking tobacco control research in Poland. The circumscribed capacity to undertake multidisciplinary policy research limits both the quality and quantity of such studies. There is an urgent need to establish a nationally coordinated plan for surveillance of data collection, use, access and dissemination, with defined institutional roles

    In Ethiopia, information regarding highland malaria transmission is scarce, and no report has been presented from Butajira highland so far whether the appearance of malaria in the area was due to endemicity or due to highland malaria transmission. Thus this study aimed to determine the presence and magnitude of malaria transmission in Butajira. For parasitological survey, longitudinal study was conducted from October to December 2006. The entomological surveys were done from October to December 2006 and continued from April to May 2007. Both parasitological and entomological surveys were done using standard procedures. The parasitological result in all the survey months (October-December) showed an overall detection rate of 4.4% (48/1082) (CI 95%; 3.2-5.7%) malaria parasite. Among infected individuals, 32 (3.0%) of the infection was due to Plasmodium vivax and the rest 16 (1.5%) were due to Plasmodium falciparum. The highest prevalence 39(3.6%) of the parasite was observed in age groups of above 15 years old. Among the total tested, 25(2.3%) of males and 23(2.1%) of females had malaria infection. Among tested individuals, 38(5.3%) and 10 (2.7%) of infection was occurred in Misrak-Meskan (2100 m a.s.l) and Mirab-Meskan (2280 m a.s.l), respectively which was statistically significant (X2=3.72, P0.05). The entomological survey showed a collection of 602 larvae and 80 adult Anopheles. Anopheles christyi was the dominant species both in the first (45.3%) and in the second (35.4%) surveys; where as, Anopheles gambiae sensu lato comprised 4.7% and 14.6%, in the first and second surveys, respectively. Anopheles gambiae s.l comprises 55% of the adult collection, and both species were collected more from outdoors (57.5%). The number of An. christyi was higher in Mirab-Meskan (58. 3%) than Misrak-Meskan (41.7%) (Prisk of malaria and its control programme in the area must be given adequate attention to minimize potential epidemics.

    A large outbreak of tularemia occurred in Kosovo in the early postwar period, 1999-2000. Epidemiologic and environmental investigations were conducted to identify sources of infection, modes of transmission, and household risk factors. Case and control status was verified by enzyme-linked immunosorbent assay, Western blot, and microagglutination assay. A total of 327 serologically confirmed cases of tularemia pharyngitis and cervical lymphadenitis were identified in 21 of 29 Kosovo municipalities. Matched analysis of 46 case households and 76 control households suggested that infection was transmitted through contaminated food or water and that the source of infection was rodents. Environmental circumstances in war-torn Kosovo led to epizootic rodent tularemia and its spread to resettled rural populations living under circumstances of substandard housing, hygiene, and sanitation.

    The colored wood statues in the CaoXi Temple represent the Sandashi(Manjushri, Samantabhadra , Avalokitesvar) in the Buddhism.These statues with great value were carved in Dali kingdom of the Song dynasty. Because of natural and man-made reasons, disease has become very seriously both in the painted layer on the surface and the structure inside. So it is very important to record the current situation, analyze the structure, craft and material, and detect the cause of disease. This paper takes the colored wood statues as the research object, and kinds of digital survey technology were applied in the process. The Research results will play an important role in the protection, explanation and display.

    Objectives To examine whether respondents to a survey of health and physical activity and potential determinants could be grouped according to the questions they missed, known as ‘item missing’. Design Observational study of longitudinal data. Setting Residents of Brisbane, Australia. Participants 6901 people aged 40–65 years in 2007. Materials and methods We used a latent class model with a mixture of multinomial distributions and chose the number of classes using the Bayesian information criterion. We used logistic regression to examine if participants’ characteristics were associated with their modal latent class. We used logistic regression to examine whether the amount of item missing in a survey predicted wave missing in the following survey. Results Four per cent of participants missed almost one-fifth of the questions, and this group missed more questions in the middle of the survey. Eighty-three per cent of participants completed almost every question, but had a relatively high missing probability for a question on sleep time, a question which had an inconsistent presentation compared with the rest of the survey. Participants who completed almost every question were generally younger and more educated. Participants who completed more questions were less likely to miss the next longitudinal wave. Conclusions Examining patterns in item missing data has improved our understanding of how missing data were generated and has informed future survey design to help reduce missing data. PMID:29084795

    Ray, Tiffany Monique

    The purpose of this study was to investigate the significant factors influencing STEM major selection by African American females. A quantitative research design with a qualitative component was employed. Ex post facto survey research was conducted utilizing an online questionnaire to collect data from participants. African American undergraduate females that had declared a major in STEM comprised the target population for the study. As a basis for comparison, a second data collection ensued. All non-African American undergraduate females majoring in STEM also received the survey instrument to determine if there was a significant difference between factors that influence STEM major selection between the two groups. The Social Cognitive Career Choice Model comprised the conceptual framework for this study. Frequencies and percentages illustrated the demographic characteristics of the sample, as well as the average influence levels of each of the items without regard for level of significance. The researcher conducted an independent samples t-test to compare the mean scores for undergraduate African American females majoring in STEM and non-African American females majoring in STEM on each influential factor on the survey instrument. The researcher coded responses to open-ended questions to generate themes and descriptions. The data showed that African American female respondents were very influenced by the following items: specific interest in the subject, type of work, availability of career opportunities after graduation, parent/guardian, precollege coursework in science, and introductory college courses. In addition, the majority of respondents were very influenced by each of the confidence factors. African American females were overwhelmingly not influenced by aptitude tests. African American females were more influenced than their non-African American female counterparts for the following factors: reputation of the university, college or department, high level

    The integration of geological and multi-electrode resistivity surveys has been carried out in Kampung Rahmat village and its vicinity, in Jeli district, Kelantan, Malaysia as part of the groundwater resources exploration for rural water supply. A geological survey in the study area has shown that the area consists of some topographic units: mountainous area, hilly area, and low-lying to undulating area. The study area is lithologically composed of granitic rocks (megacrystic biotite granite porphyry) overlain by Quaternary alluvial deposits (with weathered granite). For the multi-electrode resistivity survey, the Schlumberger array with a maximum electrode spread of 200 m was conducted by employing three resistivity survey lines, where data were collected by using the ABEM Terrameter SAS 4000 and ABEM LUND ES464 electrode selector system, and processed by using RES2DINV software. The images were presented in the form of two-dimensional (2D) resistivity profiles providing a clear view of the distribution of granitic rock basement and alluvial deposits (with the weathered granite) as well as potential groundwater zones. The results show that the study area has potential groundwater resources existing in the alluvium which become the unconfined aquifers. The combination between these two methods is reliable and successful in identifying potentially favorable zones for obtaining groundwater in the study area.

    This survey of the Canada Country Study (CCS) highlighted some beliefs of an informed group of climate change experts that can be used to develop communication strategies on this issue. The CCS was a national assessment of the social, economic and ecological impacts of climate change. It focused on 12 economic factors, 5 geographical regions and several related issues. The CCS provided useful information on what is known about climate change impacts in Canada, but it did not explore what scientists and researchers believe about climate change, including the certainty of climate change, causes, impacts, responsibility for action and future information needs. The beliefs of the highly educated are critical because they play a major role in risk communication, policy development and research. For that reason, a symposium was held in November 1997 in which Canadian climate change experts and stakeholders gathered to address the issues of awareness, understanding and actions. More than 80 per cent of the participants suggested that climate change was certain, or likely, to occur along with impacts of sea level rise and increases in droughts, floods and insect infestations. Two per cent of the respondents felt that an increase of 1.5 degrees Celsius in the next 50 years was very unlikely, 7 per cent felt it was somewhat unlikely. While the respondents recognized negative impacts, they were perceived to be more likely to occur elsewhere and not likely to pose personal threats. The issue which had the greatest ambivalence in terms of being a cause of climate change or not, was the depletion of ozone in the upper atmosphere. Survey respondents felt they were less informed about adaptation, limitation strategies and climate change detection and wanted more information on the consequences of changes to temperature and precipitation as well as social and economic impacts. It was concluded that industry/business, as well as governments are accountable for taking action on

    Large nuclear reactors such as the Advanced Heavy Water Reactor (AHWR), are susceptible to xenon-induced spatial oscillations in which, though the core average power remains constant, the power distribution may be nonuniform as well as it might experience unstable oscillations. Such oscillations influence the operation and control philosophy and could also drive safety issues. Therefore, large nuclear reactors are equipped with spatial controllers which maintain the core power distribution close to desired distribution during all the facets of operation and following disturbances. In this paper, the case of AHWR has been considered, for which a number of different types of spatial controllers have been designed during the last decade. Some of these designs are based on output feedback while the others are based on state feedback. Also, both the conventional and modern control concepts, such as linear quadratic regulator theory, sliding mode control, multirate output feedback control and fuzzy control have been investigated. The designs of these different controllers for the AHWR have been carried out using a 90th order model, which is highly stiff. Hence, direct application of design methods suffers with numerical ill-conditioning. Singular perturbation and time-scale methods have been applied whereby the design problem for the original higher order system is decoupled into two or three subproblems, each of which is solved separately. Nonlinear simulations have been carried out to obtain the transient responses of the system with different types of controllers and their performances have been compared.

Their response was very positive on parameters which were focused towards taxation policies (Rebate, government technological support, financial support and loan facilities. In addition to this, the results were further investigated and measured through statistical measures such as mean/average, which indicate that majority of enterprises, were not happy with country\\'s administration in terms of support they receive. Whereas, there are noticeable indications that government\\'s assistance to small and medium enterprises is very necessary at every stage. Enterprises which have received assistance from their governments have proved to be successful in developing nations.

  8. Investigating Cooperative Behavior in Ecological Settings: An EEG Hyperscanning Study.

    Jlenia Toppi

    Full Text Available The coordinated interactions between individuals are fundamental for the success of the activities in some professional categories. We reported on brain-to-brain cooperative interactions between civil pilots during a simulated flight. We demonstrated for the first time how the combination of neuroelectrical hyperscanning and intersubject connectivity could provide indicators sensitive to the humans' degree of synchronization under a highly demanding task performed in an ecological environment. Our results showed how intersubject connectivity was able to i characterize the degree of cooperation between pilots in different phases of the flight, and ii to highlight the role of specific brain macro areas in cooperative behavior. During the most cooperative flight phases pilots showed, in fact, dense patterns of interbrain connectivity, mainly linking frontal and parietal brain areas. On the contrary, the amount of interbrain connections went close to zero in the non-cooperative phase. The reliability of the interbrain connectivity patterns was verified by means of a baseline condition represented by formal couples, i.e. pilots paired offline for the connectivity analysis but not simultaneously recorded during the flight. Interbrain density was, in fact, significantly higher in real couples with respect to formal couples in the cooperative flight phases. All the achieved results demonstrated how the description of brain networks at the basis of cooperation could effectively benefit from a hyperscanning approach. Interbrain connectivity was, in fact, more informative in the investigation of cooperative behavior with respect to established EEG signal processing methodologies applied at a single subject level.

    2007-07-01

    Full Text Available Abstract Background As ecologic studies are often inexpensive to conduct, consideration of the magnitude and direction of ecologic biases may be useful in both study design and sensitivity analysis of results. This paper examines three types of ecologic bias: confounding by group, effect measure modification by group, and non-differential exposure misclassification. Methods Bias of the risk difference on the individual and ecologic levels are compared using two-by-two tables, simple equations, and risk diagrams. Risk diagrams provide a convenient way to simultaneously display information from both levels. Results Confounding by group and effect measure modification by group act in the same direction on the individual and group levels, but have larger impact on the latter. The reduction in exposure variance caused by aggregation magnifies the individual level bias due to ignoring groups. For some studies, the magnification factor can be calculated from the ecologic data alone. Small magnification factors indicate little bias beyond that occurring at the individual level. Aggregation is also responsible for the different impacts of non-differential exposure misclassification on individual and ecologic studies. Conclusion The analytical tools developed here are useful in analyzing ecologic bias. The concept of bias magnification may be helpful in designing ecologic studies and performing sensitivity analysis of their results.

This study investigated the prevalence of non-speaking up despite concerns for safety and aimed to identify predictors for withholding voice among healthcare professionals (HCPs) in oncology. A self-administered questionnaire assessed safety concerns, speaking up beliefs and behaviours among nurses and doctors from nine oncology departments. Multiple regression analysis was used to identify predictors for withholding safety concerns. A total of 1013 HCPs returned the completed survey (response rate 65%). Safety concerns were common among responders. Fifty-four per cent reported to recognise their colleagues making potentially harmful errors at least sometimes. A majority of responders reported at least some episodes of withholding concerns about patient safety. Thirty-seven per cent said they remained silent at least once when they had information that might have helped prevent an incident. Respondents believed that a high level of interpersonal, communication and coping skills are necessary to speak up about patient safety issues at their workplace. Higher levels of perceived advocacy for patient safety and psychological safety significantly decreased the frequency of withholding voice. Remaining silent about safety concerns is a common phenomenon in oncology. Improved strategies are needed to support staff in effective communication and make cancer care safer. © 2014 John Wiley & Sons Ltd.

  20. A STUDY ON THE POTENTIAL OF COST AND ENERGY - A SURVEY AT PLAYFORD BUILDING, UNIVERSITY OF SOUTH AUSTRALIA

    Directory of Open Access Journals (Sweden)

    J. Ramli

    2011-12-01

    Full Text Available This report summarizes a study on energy consumption of a building, and offers recommendations to reduce the cost of energy usage. Playford building, of the University of South Australia, has been chosen as the study example for completing this survey. The study uses three phases of workflow: an audit of historical energy consumption data, a screening survey, and a detailed investigation and analysis of the building itself. One year of past data have been retrieved and analyzed. Causes of energy wastage and areas with potential for energy savings have been identified by walk-through survey across two levels of the building, chosen to represent the entire building. Possible ways of reducing energy consumption have been recommended. An estimation of the energy savings, following implementation of the recommendations, has been calculated including costs that would be incurred. It was found that for six recommendations, an estimated 20.4% of energy could be saved relative to present consumption. An amount of $AUD 11264.5 per annum could be saved by the university on utility bills for electrical appliances based on an average price of electricity of 0.114592 c/kWh.

    Workplace aggression remains an important source of distress among nurses and midwives and has negative effects on staff health, patient care and organisations' reputation and fiscal health. To report on the nature and extent of workplace aggression, including bullying experienced by nurses and midwives in Victoria, Australia. A descriptive study design was chosen. The Nurses Board of Victoria posted 5000 surveys to the randomly selected registered nurses and midwives in Victoria, Australia, in 2010. The participants were asked about their experiences of violence (from clients) and bullying (from colleagues) within their most recent four working weeks. In addition, the study investigated staff actions following incidents, staff training and safety at work, and what staff believe contribute to incidents. Data analysis involved descriptive statistics, including frequencies and percentages. Chi square tests and P value were used to assess differences in categorical data. 1495 returned questionnaires were included in the study (30% response rate). Over half of the participants (52%) experienced some form of workplace aggression. Thirty-six percent experienced violence mostly from patients or their visitors/relatives and 32% experienced bullying mostly from colleagues or from their managers/supervisors. Significant differences were found between those who experienced aggression from patients and those who were bullied in respect to handling of incidents; factors thought to contribute to incidents; and organisations' handling of incidents. The study suggests that staff are less worried by patient initiated aggression compared to bullying from colleagues. For all types of aggression, respondents clearly wanted better/more realistic training, as well as enforcement of policies and support when incidents arise. Copyright © 2012 Elsevier Ltd.

    2017-06-01

    (Abstract only) The Observatorio Astrofísico de Javalambre (OAJ) is a new astronomical facility located in mainland Spain. This observatory is equipped with telescopes with large field of view and a unique filter system. The first two surveys to be carried out at the OAJ are the Javalambre Photometry of the Local Universe Survey (J-PLUS) and the Javalambre Physics of the accelerating universe Astrophysical Survey (J-PAS), devoted to the study of the star formation in the local universe and the expansion of the universe through baryonic acoustic oscillations. I introduce the OAJ and its instrumentation but also the potential for the study of variable sources (both within the J-PLUS and J-PAS projects and through "open time" projects). Finally, I stress the use of APASS for the calibration of our instruments.

    The trend in the study of areas of land in their integrity and as dynamic, anthropic units in diachronic history has initiated long survey campaigns over several decades that have covered large areas mapping the evidence and attempting a reconstruction of the evolution of ancient settlements. The need for further study to disentangle the knots of modes and types of settlement boosted further investigations of targeted excavations, based on the quality and density of the findings from the field. Currently archaeological research can rely on non-invasive integrated methods to better define the areas to be investigated systematically obtaining new typologies of information and better management of time and research costs. In this paper we present a specific case study in which a variety of integrated survey methods have contributed to the documentation and analysis of monumental complexes linked to specific local contexts. The area under investigation lies in Italy, in the province of Potenza and, specifically in the town of Forenza. The survey activities, involving the entire municipality, have been running on and off for about 2 years and have already resulted in the collection of a lot of interesting data that will be useful to essential fieldwork. In particular, we carried out different types of investigation in three different sample sites: 1. monumental complex of Santa Maria de 'Armenis: to complement previous excavations which involved only a portion of the estimated area of interest, we carried out magnetometric and geo-electrical surveys aimed at a more precise definition of the true extent and interpretation of the monument in antiquity; 2. site of Monte Caruso: we carried out remote sensing using a remote-controlled UAV hexakopter drone with stereoscopic photogrammetric survey techniques aimed at the detailed documentation of the monumental evidence of a structure visible in elevation but in a context difficult to approach with traditional surveying

    According to previous studies reporting the anesthetic/analgesic action of oral topical doxepin administration, this study evaluated a model of buccal permeation to determine the depth of delivery of doxepin into excised porcine buccal mucosa following topical application of a saturated aqueous doxepin solution. Buccal mucosa permeation studies were performed using Franz diffusion cells. Cumulative amounts of doxepin permeated were plotted as a function of time. Kinetic permeation parameters as flux (Js), lag time (Tl) and permeability coefficient (Kp) were calculated. Theoretical human plasmatic steady-state doxepin concentration and drug retained in the tissue were also determined in order to evaluate its potential therapeutic use, central or peripheral. Finally, a histological evaluation of the buccal mucosa was performed to test potential damage due to the permeation phenomenon. Obtained results showed a poor aqueous doxepin permeation through buccal mucosa membrane (median parameters Js=34.79 μg/h, Kp=0.49×10(-3)cm/h and Tl=2.8h). Predicted doxepin plasma concentrations would reach 46 ng/mL, far from the required to have central nervous system activity as tricyclic agent. However, median doxepin amount remaining in the mucosa membrane was 0.24 μg/cm(2)/μg tissue, which evidenced a reservoir function of the buccal mucosa. Histologically, no structural damage was observed in the tissues. This study lays the foundation for further research within this area with a view to potentially adopting alternative strategies for enhanced buccal absorption of doxepin in clinical practice.

    This study represents an attempt of showing own author's example of using basic research data as an inspiration for the clinical studies. The project evaluates the role of gastrin in colorectal carcinogenesis as well as the differences of its action in proximal and distal colon. Colonocytes were isolated from Fischer-344 rats and incubated for 2 minutes with gastrin (10(-8)M). This treatment resulted with 60-70% rise in tyrosine kinase (Tyr-k) and 150-200% - in phospholipase C activity as regards to basal levels. In vivo infusion of gastrin for 5 days to Fischer-344 rats resulted with 90-150% increase in distal but not proximal colonic mucosal proliferative activity as well as tyrosine phosphorylation of several colonic mucosal proteins. In clinical study, the mean fasting gastrin level in the control group was significantly lower (p<0.01) than in patients with colorectal cancer before surgery. Mean plasma gastrin level in patients with distal tumor yielded 105,31 +/- 12,5 microU/l and was significantly higher than in patients with the proximal tumor site (42, 2 +/- 3,1 microU/l) (p<0,001). We conclude, that Tyr-k is involved in the mechanism of the trophic action of gastrin, particularly in distal colon. The differences in gastrin concentration in patients with distal and proximal tumors may probably contribute to the distinct pathogenesis and biological properties of those cancers.

  8. Studies of photodynamic therapy: Investigation of physiological mechanisms and dosimetry

    Science.gov (United States)

    Woodhams, Josephine Helen

    Photodynamic therapy (PDT) is a treatment for a range of malignant and benign lesions using light activated photosensitising drugs in the presence of molecular oxygen. PDT causes tissue damage by a combination of processes involving the production of reactive oxygen species (in particular singlet oxygen). Since the PDT cytotoxic effect depends on oxygen, monitoring of tissue oxygenation during PDT is important for understanding the basic physiological mechanisms and dosimetry of PDT. This thesis describes the use of non-invasive, optical techniques based on visible light reflectance spectroscopy for the measurement of oxy- to deoxyhaemoglobin ratio or haemoglobin oxygen saturation (HbSat). HbSat was monitored at tissue sites receiving different light dose during aluminium disulphonated phthalocyanine (AIS2PC) PDT. Results are presented on real time PDT-induced changes in HbSat in normal tissue (rat liver) and experimental tumours, and its correlation with the final biological effect under different light regimes, including fractionated light delivery. It was found to some extent that changes in HbSat could indicate whether the tissue would be necrotic after PDT and it was concluded that online physiological dosimetry is feasible for PDT. The evaluation of a new photosensitiser for PDT called palladium-bacteriopheophorbide (WST09) has been carried out in normal and tumour tissue in vivo. WST09 was found to exert a strong PDT effect but was active only shortly after administration. WST09 produced substantial necrosis in colonic tumours whilst only causing a small amount of damage to the normal colon under certain conditions indicating a degree of selectivity. Combination therapy with PDT for enhancing the extent of PDT-induced damage has been investigated in vivo by using the photochemical internalisation (PCI) technique and Type 1 mechanism enhanced phototoxicity with indole acetic acid (IAA).

    Full Text Available Tourism destination brand equity is defined as all assets (or debts of brands provided with name and symbol of tourism destination to make changes in value services of experiences. In many cases, brand equity is more than physical assets. This survey performs an investigation to identify effective factors in tourism destination equity, cause and affects relationships, and proposes a model for perceived value of tourism destination. The proposed study is performed in one of free islands named Gheshm. The preliminary results indicate that there is a positive relationship between tourism destination brand awareness and destination brand equity, tourism destination brand image, destination brand equity and tourism destination brand loyalty.

    Full Text Available Osteoporosis is common in ankylosing spondylitis (AS, which is a chronic inflammatory rheumatic disease.The aim of this study was to assess the bone loss and the effects of disease activity on bone mineral density in patients with AS. Thirty-three (29 men ,4 women patients with AS were included in the study. All of the patients were evaluated as their age, sex, height, weight, history, physical examination, laboratory and AP-lateral thoracic and lumbar vertebrae radiographic findings. Control group was consisted of 35 (31 men 4 women age and sex-matched healthy person. Mean age and disease duration of the patient group were 43.2 ± 9.9 and 13.18 ± 10.6 years, respectively. Bone mineral density (BMD was measured by dual energy x-ray absorptiometry (DXA at lumbar spine and proximal femur regions. BMD did not show statistically significant difference at lumbar region between two groups. However BMD values were 10% lower at femur neck in patient group than controls. The rate of osteopenia and osteoporosis was 42.8 % at the femur neck region in the patient group and 22.8 % in the control group. BMD values at femur neck correlated with age and disease duration. There was no correlation between BMD and BASDAI and BASMI, BASFI, BASGI scores. In conclusion, bone loss is common in AS. Ligament calcification and syndesmophytes may lead to higher BMD values at lumbar region in AS .Thus proximal femur BMD is valuable in the patients with long disease duration. Disease activity has no negative effect on bone density in our study. (Osteoporoz Dünyasından 2006;12:81-3

    The aim of this study was to describe the crash characteristics and patient outcomes of a sample of patients admitted to hospital following bicycle crashes. Injured cyclists were recruited from the two major trauma services for the state of Victoria, Australia. Enrolled cyclists completed a structured interview, and injury details and patient outcomes were extracted from the Victorian State Trauma Registry (VSTR) and the Victorian Orthopaedic Trauma Outcomes Registry (VOTOR). 186 cyclists consented to participate in the study. Crashes commonly occurred during daylight hours and in clear weather conditions. Two-thirds of crashes occurred on-road (69%) and were a combination of single cyclist-only events (56%) and multi-vehicle crashes (44%). Of the multi-vehicle crashes, a motor vehicle was the most common impact partner (72%) and distinct pre-crash directional interactions were observed between the cyclist and motor vehicle. Nearly a quarter of on-road crashes occurred when the cyclist was in a marked bicycle lane. Of the 31% of crashes that were not on-road, 28 (15%) occurred on bicycle paths and 29 (16%) occurred in other locations. Crashes on bicycle paths commonly occurred on shared bicycle and pedestrian paths (83%) and did not involve another person or vehicle. Other crash locations included mountain bike trails (39%), BMX parks (21%) and footpaths (18%). While differences in impact partners and crash characteristics were observed between crashes occurring on-road, on bicycle paths and in other locations, injury patterns and severity were similar. Most cyclists had returned to work at 6 months post-injury, however only a third of participants reported a complete functional recovery. Further research is required to develop targeted countermeasures to address the risk factors identified in this study. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Large-scale sample surveys to estimate abundance and distribution of organisms and their habitats are increasingly important in ecological studies. Multi-stage sampling (MSS) is especially suited to large-scale surveys because of the natural clustering of resources. To illustrate an application, we: (1) designed a stratified MSS to estimate late autumn abundance (kg/ha) of rice seeds in harvested fields as food for waterfowl wintering in the Mississippi Alluvial Valley (MAV); (2) investigated options for improving the MSS design; and (3) compared statistical and cost efficiency of MSS to simulated simple random sampling (SRS). During 2000?2002, we sampled 25?35 landowners per year, 1 or 2 fields per landowner per year, and measured seed mass in 10 soil cores collected within each field. Analysis of variance components and costs for each stage of the survey design indicated that collecting 10 soil cores per field was near the optimum of 11?15, whereas sampling >1 field per landowner provided few benefits because data from fields within landowners were highly correlated. Coefficients of variation (CV) of annual estimates of rice abundance ranged from 0.23 to 0.31 and were limited by variation among landowners and the number of landowners sampled. Design effects representing the statistical efficiency of MSS relative to SRS ranged from 3.2 to 9.0, and simulations indicated SRS would cost, on average, 1.4 times more than MSS because clustering of sample units in MSS decreased travel costs. We recommend MSS as a potential sampling strategy for large-scale natural resource surveys and specifically for future surveys of the availability of rice as food for waterfowl in the MAV and similar areas.

    This study examined data equivalency and loss to follow-up rates from Internet and interactive voice response (IVR) system surveys in a prospective-cohort study. 475 limited-service restaurant workers participating in the 12-week study were given a choice to report their weekly slipping experience by either IVR or Internet. Demographic differences, loss to follow-up, self-reported rates of slipping, and selection of first and last choices were compared. Loss to follow-up rates were slightly higher for those choosing the IVR mode. Rates of slipping and selection of first and last choices were not significantly different between survey modes. Propensity to choose an Internet survey decreased with increasing age, and was the lowest among Spanish speakers (5%) and those with less than a high school education (14%). Studies relying solely on Internet-based data collection may lead to selective exclusion of certain populations. Findings suggest that Internet and IVR may be combined as survey modalities within longitudinal studies. Copyright © 2014 The Authors. Published by Elsevier Inc. All rights reserved.

  16. Investigating internet use by mental health service users: interview study.

    2007-01-01

    The internet is an increasingly important source of mental health-related information, and has the potential to be harnessed as a tool to support self-care and informed decision-making. Yet little is known about the motivations and attitudes of users. We therefore undertook a qualitative interview study with a purposive sample of mental health service users with internet experience, to explore issues with respect to mental health-related internet use. One of the prime motivations for online mental health seekers was to find experiential information from other people with similar problems. This information allowed users to know they were not alone, and to instill hope that others in the same situation had recovered. Benefits of the internet as an information source included convenience, privacy and anonymity. Problems related more to misuse of the internet rather than concerns over inaccuracy. Such qualitative work is important in an emerging research area to understand internet use better.

    The magnitude of participation bias due to non-participation should be considered for cancer patients invited to population-based surveys. We studied participation rates among persons with and without cancer in a large population based study, the Nord-Trøndelag Health Study (HUNT). Citizens 20 years or above living in the Nord-Trøndelag County of Norway have been invited three times to comprehensive health surveys. The invitation files with data on sex, invitation date and participation were linked to the Cancer Registry of Norway. In a first step unadjusted crude participation rates (participants/invited persons) were estimated for cancer patients (CaPts) and non-cancer persons (NonCaPers), followed by logistic regression analyses with adjustment for age and sex. To evaluate the "practical" significance of the estimated odds ratios in the cancer diagnosis group, relative risks were also estimated comparing the observed rates to the estimated rates under the counterfactual assumption of no earlier cancer diagnosis among CaPts. Overall 3 % of the participants in the three HUNT studies were CaPts and 59 % of them had been diagnosed with their first life-time cancer >5 years prior to each survey. In each of the three HUNT surveys crude participation rates were similar for CaPts and NonCaPers. Adjusted for sex and age, CaPts' likelihood to participate in HUNT1 (1984-86) and HUNT2 (1995-97), but not in HUNT3 (2006-2008), was statistically significantly reduced compared to NonCaPers, equaling a relative risk of 0.98 and 0.96, respectively. The lowest odds ratio emerged for CaPts diagnosed during the last 2 years preceding a HUNT invitation. Only one-third of CaPts participating in a survey also participated in the subsequent survey compared to approximately two-thirds of NonCaPers, and 11 % of CaPts participated in all three HUNT surveys compared to 37 % of NonCaPers. In the three HUNT surveys no or only minor participation bias exist as to CaPts' participation rates

  19. Dr. med. – obsolete? A cross sectional survey to investigate the perception and acceptance of the German medical degree

    2014-01-01

    Purpose: To obtain the German Medical Degree “Dr.med.” candidates are required to write a scientific thesis which is usually accomplished during Medical school education. This extra work load for the students amongst a lack of standardization and an M.D. awarded upon graduation in other European and Anglo-Saxon countries leads repeatedly to criticism of the German system. However, a systematic survey on the perception and acceptance of the German doctoral thesis among those affected is overdue. Methods: Using an online questionnaire, medical students as well as licensed doctors were asked for the status of their medical degree, their motivation, personal benefit, time and effort, scientific output, its meaningfulness and alternatives concerning their thesis. Patients were asked, how important they value their general practitioner’s title “Dr. med.”. The resulting data were evaluated performing basic statistic analyses. Results and Conclusions: The title “Dr. med.“ does not seem to be obsolete, but there is room for improvement. The scientific output is good and only a mere 15.1% of the candidates do not publish their results at all. Moreover, while at an early stage motivation, appreciation and recognition of personal benefits from the medical degree are considered as independent aspects, they merge to a general view at later stages. The current practice is considered most meaningful by the ones who have already finished their thesis. However, there are discrepancies between the expected and the actual length as well as the type of the thesis indicating that mentoring and educational advertising need improvement. As for the patients, their educational level seems to correlate with the significance attributed to the title “Dr. med.” held by their physician. PMID:25228932

    To obtain the German Medical Degree "Dr.med." candidates are required to write a scientific thesis which is usually accomplished during Medical school education. This extra work load for the students amongst a lack of standardization and an M.D. awarded upon graduation in other European and Anglo-Saxon countries leads repeatedly to criticism of the German system. However, a systematic survey on the perception and acceptance of the German doctoral thesis among those affected is overdue. Using an online questionnaire, medical students as well as licensed doctors were asked for the status of their medical degree, their motivation, personal benefit, time and effort, scientific output, its meaningfulness and alternatives concerning their thesis. Patients were asked, how important they value their general practitioner's title "Dr. med.". The resulting data were evaluated performing basic statistic analyses.

    We recently read with interest "An exploratory study using framework analysis to investigate health-seeking behaviour in patients with psoriasis" by Simpson et al. This interview based-study added to the understanding of obstacles patients face when seeking psoriasis treatment. Given the recent advances in effective systemic treatment options for psoriasis, we were similarly interested in exploring the discordance between available therapies and patient satisfaction and outcomes using a survey in a larger series of patients.

    Computational bioinformatics workflows are extensively used to analyse genomics data, with different approaches available to support implementation and execution of these workflows. Reproducibility is one of the core principles for any scientific workflow and remains a challenge, which is not fully addressed. This is due to incomplete understanding of reproducibility requirements and assumptions of workflow definition approaches. Provenance information should be tracked and used to capture all these requirements supporting reusability of existing workflows. We have implemented a complex but widely deployed bioinformatics workflow using three representative approaches to workflow definition and execution. Through implementation, we identified assumptions implicit in these approaches that ultimately produce insufficient documentation of workflow requirements resulting in failed execution of the workflow. This study proposes a set of recommendations that aims to mitigate these assumptions and guides the scientific community to accomplish reproducible science, hence addressing reproducibility crisis. Reproducing, adapting or even repeating a bioinformatics workflow in any environment requires substantial technical knowledge of the workflow execution environment, resolving analysis assumptions and rigorous compliance with reproducibility requirements. Towards these goals, we propose conclusive recommendations that along with an explicit declaration of workflow specification would result in enhanced reproducibility of computational genomic analyses.

    The search for neutrinoless double- β decay (0 νββ) of 76Ge has led to renewed interest in the structure of this mass region, as structural information helps constrain calculations of the 0 νββ nuclear matrix elements. The structure of many of the even-even Ge isotopes, including 76Ge, show interesting features, such as low-lying 0+ states that have been interpreted as evidence for shape coexistence, as well as indications of triaxiality. Of fundamental importance in understanding the nature of the excited states in 76Ge is the determination of transition strengths, which has been obtained through 76Ge(n,n' γ) studies at the University of Kentucky and the 76Ge (γ ,γ') reaction at the High Intensity γ-Ray Source at Duke University. The measured transition strengths support the identification of band structure in 76Ge, a newly observed mixed-symmetry state, and the M1 scissors mode. This material is based upon work supported by the U.S. National Science Foundation under Grant No. PHY-1606890.

    Fibrinogen as precursor of fibrin plays an essential role in clot formation. There are three main mechanisms associated with a reduction in fibrinogen concentration during cardiac surgery: hemodilution, consumption, and degradation. Moreover, early fibrinogen degradation products (FgDPs) can interfere with normal fibrin formation of intact fibrinogen. The aim of this study was to determine the relative contributions of hemodilution, consumption, and degradation to fibrinogen loss in cardiac surgery and to evaluate the effects fibrinogen degradation products on blood clot formation in vitro. First, fibrin and fibrinogen concentrations, their degradation products, hematocrit, and albumin concentrations were compared in 10 patients before and after isolated coronary artery bypass graft (CABG) surgery with cardiopulmonary bypass. Second, ex-vivo fibrinogen supplementation experiments were performed. Finally, the effects of purified FgDPs on clotting time and clot firmness were established in vitro in whole blood by ROTEM. Fibrinogen plasma concentration decreased 30% during surgery. This drop appears to be mainly caused by hemodilution, as both hematocrit and albumin levels decreased and no relevant increase in D-dimer levels and FgDPs was observed. Furthermore, the coagulation profile normalized after addition of purified fibrinogen. Early FgDPs demonstrated a significant impact on in-vitro whole blood clotting. Although early FgDPs have a pronounced effect on blood clot formation in vitro and therefore may induce or enhance in vivo coagulopathy, the drop of fibrinogen concentration seen after CABG surgery (using tranexamic acid) is primarily caused by hemodilution.

    A key issue in the field of inclusive design is the ability to provide designers with an understanding of people's range of capabilities. Since it is not feasible to assess product interactions with a large sample, this paper assesses a range of proxy measures of design-relevant capabilities. It describes a study that was conducted to identify which measures provide the best prediction of people's abilities to use a range of products. A detailed investigation with 100 respondents aged 50-80 years was undertaken to examine how they manage typical household products. Predictor variables included self-report and performance measures across a variety of capabilities (vision, hearing, dexterity and cognitive function), component activities used in product interactions (e.g. using a remote control, touch screen) and psychological characteristics (e.g. self-efficacy, confidence with using electronic devices). Results showed, as expected, a higher prevalence of visual, hearing, dexterity, cognitive and product interaction difficulties in the 65-80 age group. Regression analyses showed that, in addition to age, performance measures of vision (acuity, contrast sensitivity) and hearing (hearing threshold) and self-report and performance measures of component activities are strong predictors of successful product interactions. These findings will guide the choice of measures to be used in a subsequent national survey of design-relevant capabilities, which will lead to the creation of a capability database. This will be converted into a tool for designers to understand the implications of their design decisions, so that they can design products in a more inclusive way.

    For 14 nights in March 2007, we used two telescopes at the Cerro Tololo Inter-American Observatory (CTIO) in Chile to study the nature of space debris at Geosynchronous Earth Orbit (GEO). In this project one telescope was dedicated to survey operations, while a second telescope was used for follow-up observations for orbits and colors. The goal was to obtain orbital and photometric information on every faint object found with the survey telescope. Thus we concentrate on objects fainter than R = 15th magnitude.

It is recognized that the core damage frequency (CDF) of the sequence evaluated in this scoping effort would be considerably lower if evaluations considered new FLEX equipment being installed by industry. Nevertheless, because of uncertainties in instrumentation response when exposed to conditions beyond QE limits and alternate challenges associated with different sequences that may impact sensor performance, it is recommended that additional evaluations of instrumentation performance be completed to provide confidence that operators have access to accurate, relevant, and timely information on the status of reactor systems for a broad range of challenges associated with risk important severe accident sequences.

    Although large herds (more than 500 cows) only represent 13% of Australian dairy farms, they represent more than 35% of the cows milked. A survey of Australian dairy farmers was conducted to assess relationships between herd size and known or proposed risk factors for adverse animal welfare outcomes in Australian dairy herds in relation to increasing scale of production. Responses from 863 Australian dairy farms (13% of Australian dairy farms) were received. Increasing herd size was associated with increases in stocking density, stock per labor unit, and grain fed per day-all of which could reasonably be hypothesized to increase the risk of adverse welfare outcomes unless carefully managed. However, increasing herd size was also associated with an increased likelihood of staff with formal and industry-based training qualifications. Herd size was not associated with reported increases in mastitis or lameness treatments. Some disease conditions, such as milk fever, gut problems, and down cows, were reported less in larger herds. Larger herds were more likely to have routine veterinary herd health visits, separate milking of the main herd and the sick herd, transition diets before calving, and written protocols for disease treatment. They were more likely to use monitoring systems such as electronic identification in the dairy, computerized records, daily milk yield or cell count monitoring, and pedometers or activity meters. Euthanasia methods were consistent between herds of varying sizes, and it was noted that less than 3% of farms make use of captive-bolt devices despite their effectiveness and ready availability. Increasing herd size was related to increased herd milking time, increased time away from the paddock, and increased distance walked. If the milking order of cows is consistent, this may result in reduced feed access for late-milking-order cows because of a difference in time away from the paddock. More than 95% of farmers believed that their cows were

    The present study, taking a resource-oriented approach to mental health, aimed at investigating mental resilience and its determinants among undergraduate physiotherapy students using quantitative and qualitative tools. A questionnaire-based cross-sectional survey supplemented by 2 focus groups. One university in Hungary. 130 physiotherapy students at years 1, 2, and 3. Sense of coherence, a measure of dynamic self-esteem, as well as social support from family and peers were used to assess mental well-being. A screening instrument for psychological morbidity and perceived stress were used as deficiency-oriented approaches. Student opinions were gathered on positive and negative determinants of mental health. Resilience was lower [mean difference 4.8 (95% CI -3.4; 13.1)], and the occurrence of psychological morbidity (32.5% vs. 0%) was higher among female compared to male students. However, the proportion of students fully supported by their peers was higher among females (63% vs. 37.5%). Female students, unlike their male counterparts, experienced higher stress compared to their peers in the general population. Social support declined as students progressed in their studies though this proved to be the most important protective factor for their mental well-being. Results were fed back to the course organizers recommending the implementation of an evidence-based method to improve social support as delineated by the Guide to Community Preventive Services of the US the outcomes of which are to be seen in the future.

    A population-based survey was conducted to investigate the epidemiology of and antifungal resistance in Spanish clinical strains of filamentous fungi isolated from deep tissue samples, blood cultures, and respiratory samples. The study was conducted in two different periods (October 2010 and May 2011) to analyze seasonal variations. A total of 325 strains were isolated in 29 different hospitals. The average prevalence was 0.0016/1,000 inhabitants. Strains were identified by sequencing of DNA targets and susceptibility testing by the European Committee for Antimicrobial Susceptibility Testing reference procedure. The most frequently isolated genus was Aspergillus, accounting for 86.3% of the isolates, followed by Scedosporium at 4.7%; the order Mucorales at 2.5%; Penicillium at 2.2%, and Fusarium at 1.2%. The most frequent species was Aspergillus fumigatus (48.5%), followed by A. flavus (8.4%), A. terreus (8.1%), A. tubingensis (6.8%), and A. niger (6.5%). Cryptic/sibling Aspergillus species accounted for 12% of the cases. Resistance to amphotericin B was found in 10.8% of the isolates tested, while extended-spectrum triazole resistance ranged from 10 to 12.7%, depending on the azole tested. Antifungal resistance was more common among emerging species such as those of Scedosporium and Mucorales and also among cryptic species of Aspergillus, with 40% of these isolates showing resistance to all of the antifungal compounds tested. Cryptic Aspergillus species seem to be underestimated, and their correct classification could be clinically relevant. The performance of antifungal susceptibility testing of the strains implicated in deep infections and multicentric studies is recommended to evaluate the incidence of these cryptic species in other geographic areas.

    After Typhoon Morakot struck Taiwan in 2009, thousands of Taiwanese citizens were displaced to shelters for several weeks. Others were placed in urban communities where they had family members. This study aimed to investigate serological status in both groups and identify risk factors associated with seroconversion of infectious diseases. A longitudinal survey. All experimental and clinical investigations were performed in a tertiary teaching hospital. A total of 288 displaced persons (96 males and 192 females) were recruited and complete follow-up data through two rounds of sampling were collected. The average age was 58.42 years (range 31-87 years). First, serum specimens were collected between December 2009 and January 2010, 4-5 months after the typhoon. The second round of specimen collection was carried out after 6 months. The primary outcome measured was serological status of vaccine-preventable droplet-borne infectious diseases (ie, measles, mumps, rubella) and water-borne diseases (ie, amoebiasis and leptospirosis). The secondary outcome was identification of risk factors for seroconversion using univariate and multivariate analyses. Complete data were available for all 288 displaced persons (114 from the shelter group; 174 from the community group). Seroconversion of Entamoeba histolytica was observed in 128 (44.4%) participants, with a significantly higher rate in the shelter group than in the community group (56.1% vs 36.8%; p=0.001). There were 10 cases of rubella seroconversion. After adjusting for medical history, hypertension and hyperlipidaemia, shelter stay was associated with higher risk for seroconversion (OR=2.055, 95% CI 1.251 to 3.374; p=0.004). Amoebiasis was more evident in the shelter group, although the manifestations were mild. Our results suggested that (1) a clean water supply is essential postdisaster, especially in crowded shelters, and (2) vaccination programmes should be extended to populations at higher risk for post

    Cost-effective approaches for identifying and enrolling subjects in community-based epidemiological studies face many challenges. Additional challenges arise when a neighborhood scale of analysis is required to distinguish between individual- and group-level risk factors with strong environmental determinants. A stratified, two-stage, cross-sectional, address-based telephone survey of Greater Tucson, Arizona, was conducted in 2002-2003. Subjects were recruited from direct marketing data at neighborhood resolution using a geographic information system (GIS). Three geomorphic strata were divided into two demographic units. Households were randomly selected within census block groups, selected using the probability proportional to size technique. Purchased direct marketing lists represented 45.2% of Census 2000 households in the surveyed block groups. Survey design effect (1.6) on coccidioidomycosis prevalence (88 per 100,000 per year) was substantially reduced in four of the six strata (0.3-0.9). Race-ethnicity was more robust than age and gender to compensate for significant selection bias using poststratification. Clustered, address-based telephone surveys provide a cost-effective, valid method for recruiting populations from address-based lists using a GIS to design surveys and population survey statistical methods for analysis. Landscape ecology provides effective methods for identifying scales of analysis and units for stratification that will improve sampling efficiency when environmental variables of interest are strong predictors.

    In 2011, the Food Safety and Modernization Act established Integrated Food Safety Centers of Excellence across the United States to train, educate, and enhance the skill of foodborne illness outbreak investigation teams. To target regional training efforts, the New York Integrated Food Safety Center of Excellence (NYCoE) identified training needs in food safety and foodborne illness investigations among public heath staff in 11 states and 1 large metropolitan area in the Northeast. To identify topics so as to develop training materials relevant to food safety and foodborne disease outbreaks in order to improve and impact foodborne outbreak investigations regionally and nationally. Cross-sectional, paper-based survey conducted in January-February 2016. Eleven Northeast and Mid-Atlantic states, and 1 large metropolitan area. Foodborne illness outbreak investigators in the NYCoE region. Identification of training needs, as self-reported by participants, regarding general foodborne outbreak investigation needs and those specific to epidemiologists, environmental health specialists, and laboratorians. Topics included basic food safety/processing knowledge, communication and metrics, and training formats. Information regarding demographics, utility of the NYCoE, and certificate programs was also collected. Surveys returned from 33 respondents (from 10 states and 1 metropolitan area) identified metrics (100%), increasing use of culture-independent diagnostic tests (85%), and guidance on implementation of the Council to Improve Foodborne Outbreak Response (guidelines (89%) as the top training needs. By field, epidemiologists cited training in applying whole genome sequencing (100%), environmental health specialists cited training on the National Outbreak Reporting System (67%), and laboratorians cited training on whole genome sequencing (91%) as important. Short, online, or in-person, 1- to 2-day trainings were the preferred training formats (≥91%). Respondents wanted

    Some recent molecular epidemiology studies of the effects of genetic and environmental factors on human health have required the enrollment of more than 100 000 participants and the involvement of regional study offices across the country. Although regional study office investigators play a critical role in these studies, including the acquisition of funds, this role is rarely discussed. We first differentiated the functions of the regional and central study offices. We then investigated the minimum number of items required and approximate cost of a molecular epidemiology study enrolling 7400 participants from a model region with a population of 100 000 for a 4-year baseline survey using a standard protocol developed based on the protocol of Japan Public Health Center-based Prospective Study for the Next Generation. The functions of the regional study office were identified, and individual expenses were itemized. The total cost of the 4-year baseline survey was 153 million yen, excluding consumption tax. Accounting difficulties in conducting the survey were clarified. We investigated a standardized example of the tasks and total actual costs of a regional study office. Our approach is easy to utilize and will help improve the management of regional study offices in future molecular epidemiology studies.

    Systemic sclerosis (SSc) is a chronic multisystem connective tissue disorder with detrimental impact on quality of life. Patients with SSc face emotional distress and frequently meet criteria for a psychiatric disorder. However, the pattern of psychiatric manifestations may vary according to socioethnic background. We investigated the prevalence of depressive and anxiety symptoms and examined their association with sociodemographic and clinical factors in Iranian SSc patients. Depressive and anxiety symptoms were evaluated by Beck Depression Inventory and Cattell questionnaire in 114 SSc patients. The associations between sociodemographic and clinical factors and depressive/anxiety symptoms were examined via multivariate analysis. The prevalence of depressive symptoms was 68.4%. There was a significant association between depressive symptoms and pulmonary and gastrointestinal manifestations. Also, diffuse SSc patients were more prone to depressive symptoms. Mean Rodnan scores were significantly higher in patients with depressive symptoms in comparison with subjects with no depressive symptoms. The prevalence of anxiety symptoms was 23.6%. Anxiety symptoms were not associated with demographic characteristics, SSc subtype, disease duration, Rodnan score, other clinical features, and previous history of depression in the patients or their family. The coincidence of anxiety and depression was 82.8%. Depressive and anxiety symptoms are prevalent among Iranian SSc population. The depressive symptoms showed correlation with pulmonary and gastrointestinal involvement, as well as diffuse SSc subtype.

    Full Text Available In 1895 the salt mine Friedrichshall (Southwestern Germany was shut down after a catastrophic water inrush. The following leaching and relocating processes led to a considerable subsidence, whose influences are still significant. In the run-up to the preparation of the building land, the mining authority in 2004 demanded further investigations to assess remaining risks at the surface.A lot of problems - which had to be solved first - were caused by discrepancies between the existing mine maps, particularly with regard to the orientation marks. By the use of digital terrain models, based both on current airborne-laserscans and historical maps, it was possible to describe the course of subsidence.Comparing the former volume of the underground mine workings as well as the volume of the surface depression, a remaining potential of the subsidence could be estimated.Starting from these results a geomechanical modelling led to a differentiated risk assessment for the designated building sites and other areas of influence.

    Full Text Available This paper reports on a new investigation of the long-standing, unresolved discrepancy between Thomson Scattering (TS and Electron Cyclotron Emission (ECE measurements of electron temperature in high temperature tokamak plasmas. At the Alcator C-Mod tokamak, ion cyclotron range of frequency (ICRF heating is used to produce high temperature conditions where the TS- ECE discrepancy, as observed in the past at JET and TFTR, should appear. Plasmas with Te(0 up to 8 keV are obtained using three different heating scenarios: Ion Cyclotron Resonance Heating (ICRH, ICRF mode conversion heating and a combination of the two heating methods. This is done in order to explore the hypothesis that ICRH-generated fast ions may be related to the discrepancy. In all high temperature cases at C-Mod, we find no evidence for the type of discrepancy reported at JET and TFTR. Here we present the C-Mod results along with a summary of past work on the TS-ECE discrepancy.

    Employment in those with disability is an important rehabilitation goal, along with achieving some measure of functional independence and is at the same time one of the most difficult goals to achieve. The number of people with disabilities participating in adaptive sports has been increasing steadily over the years. A few studies have looked at the relationship between physical fitness and employment status in those with disability, but there have been no studies that focused on the results of organized adaptive sports events affecting employment outcome. To determine whether participation in the National Veterans Wheelchair Games (NVWG) has a positive impact on employment in those with disability. Prospective, cross-sectional survey. 2015 NVWG in Dallas, Texas (nonclinic setting). A total of 338 survey participants; 36 surveys were excluded due to incompletion. Veterans who participated at the 2015 NVWG were given the opportunity to complete a 2-page survey. Survey participants received $5.00 gift card as compensation. Percentage of those who perceived NVWG made a difference in attaining employment, risk ratio analyses. A total of 50% of the participants stated that the NVWG made a difference in attaining employment. Those currently working were 1.5 times more likely to say that the NVWG had a positive effect on employment than those not currently working (P Likert scale distribution. Our study suggests that participating in the NVWG provides psychosocial support to the veterans and may have a positive influence in employment outcomes. To be determined.

    2007-02-01

    Full Text Available Abstract Background Health surveys provide important information on the burden and secular trends of risk factors and disease. Several factors including survey and item non-response can affect data quality. There are few reports on efficiency, validity and the impact of item non-response, from developing countries. This report examines factors associated with item non-response and study efficiency in a national health survey in a developing Caribbean island. Methods A national sample of participants aged 15–74 years was selected in a multi-stage sampling design accounting for 4 health regions and 14 parishes using enumeration districts as primary sampling units. Means and proportions of the variables of interest were compared between various categories. Non-response was defined as failure to provide an analyzable response. Linear and logistic regression models accounting for sample design and post-stratification weighting were used to identify independent correlates of recruitment efficiency and item non-response. Results We recruited 2012 15–74 year-olds (66.2% females at a response rate of 87.6% with significant variation between regions (80.9% to 97.6%; p Conclusion Informative health surveys are possible in developing countries. While survey response rates may be satisfactory, item non-response was high in respect of income and sexual practice. In contrast to developed countries, non-response to questions on income is higher and has different correlates. These findings can inform future surveys.

    Social media provides researchers with an efficient means to reach and engage with a large and diverse audience. Twitter allows for the virtual social interaction among a network of users that enables researchers to recruit and administer surveys using snowball sampling. Although using Twitter to administer surveys for research is not new, strategies to improve response rates are yet to be reported. To compare the potential and actual reach of 2 Twitter accounts that administered a Web-based concussion survey to rugby players and trainers using 2 distinct Twitter-targeting strategies. Furthermore, the study sought to determine the likelihood of receiving a retweet based on the time of the day and day of the week of posting. A survey based on previous concussion research was exported to a Web-based survey website Survey Monkey. The survey comprised 2 questionnaires, one for players, and one for those involved in the game (eg, coaches and athletic trainers). The Web-based survey was administered using 2 existing Twitter accounts, with each account executing a distinct targeting strategy. A list of potential Twitter accounts to target was drawn up, together with a list of predesigned tweets. The list of accounts to target was divided into 'High-Profile' and 'Low-Profile', based on each accounts' position to attract publicity with a high social interaction potential. The potential reach (number of followers of the targeted account), and actual reach (number of retweets received by each post) between the 2 strategies were compared. The number of retweets received by each account was further analyzed to understand when the most likely time of day, and day of the week, a retweet would be received. The number of retweets received by a Twitter account decreased by 72% when using the 'high-profile strategy' compared with the 'low-profile strategy' (incidence rate ratio (IRR); 0.28, 95% confidence interval (CI) 0.21-0.37, P.001) and 6 PM to 11:59 PM (IRR 1.48, 95% CI 1

    Objectives To report the methods used to assemble a contemporary pregnancy cohort for investigating influences on smoking behaviour before, during and after pregnancy and to report characteristics of women recruited. Design Longitudinal cohort survey. Setting Two maternity hospitals, Nottingham, England. Participants 3265 women who attended antenatal ultrasound scan clinics were offered cohort enrolment; those who were 8–26 weeks pregnant and were currently smoking or had recently stopped smoking were eligible. Cohort enrollment took place between August 2011 and August 2012. Primary and secondary outcome measures Prevalence of smoking at cohort entry and at two follow-up time points (34–36 weeks gestation and 3 months postnatally); response rate, participants’ sociodemographic characteristics. Results 1101 (33.7%, 95% CI 32.1% to 35.4%) women were eligible for inclusion in the cohort, and of these 850 (77.2%, 95% CI 74.6% to 79.6%) were recruited. Within the cohort, 57.4% (N=488, 95% CI 54.1% to 60.7%) reported to be current smokers. Current smokers were significantly younger than ex-smokers (p<0.05), more likely to have no formal qualifications and to not be in current paid employment compared to recent ex-smokers (p<0.001). Conclusions This contemporary cohort, which seeks very detailed information on smoking in pregnancy and its determinants, includes women with comparable sociodemographic characteristics to those in other UK cross-sectional studies and cohorts. This suggests that future analyses using this cohort and aimed at understanding smoking behaviour in pregnancy may produce findings that are broadly generalisable. PMID:24833689

    Background As health services research (HSR) expands across the globe, researchers will adopt health services and health worker evaluation instruments developed in one country for use in another. This paper explores the cross-cultural methodological challenges involved in translating HSR in the language and context of different health systems. Objectives To describe the pre-data collection systematic translation process used in a twelve country, eleven language nursing workforce survey. Design & Settings We illustrate the potential advantages of Content Validity Indexing (CVI) techniques to validate a nursing workforce survey developed for RN4CAST, a twelve country (Belgium, England, Finland, Germany, Greece, Ireland, Netherlands, Norway, Poland, Spain, Sweden, and Switzerland), eleven language (with modifications for regional dialects, including Dutch, English, Finnish, French, German, Greek, Italian, Norwegian, Polish, Spanish, and Swedish), comparative nursing workforce study in Europe. Participants Expert review panels comprised of practicing nurses from twelve European countries who evaluated cross-cultural relevance, including translation, of a nursing workforce survey instrument developed by experts in the field. Methods The method described in this paper used Content Validity Indexing (CVI) techniques with chance correction and provides researchers with a systematic approach for standardizing language translation processes while simultaneously evaluating the cross-cultural applicability of a survey instrument in the new context. Results The cross-cultural evaluation process produced CVI scores for the instrument ranging from .61 to .95. The process successfully identified potentially problematic survey items and errors with translation. Conclusions The translation approach described here may help researchers reduce threats to data validity and improve instrument reliability in multinational health services research studies involving comparisons across

    Full Text Available Understanding the link between course work and unanswered authentic research questions being explored in the research lab is an important goal in undergraduate science teaching. The activity presented here focuses on current research regarding the virulence characteristics of Streptococcus pyogenes particularly targeting the control of sugar uptake regulated via catabolite repression. Students were challenged to formulate a research question and use higher-order thinking skills to analyze data, work collaboratively to solve problems, and pose and test a hypothesis in the laboratory setting. The activity employed an interrupted case study approach using both online and face-to-face settings. The case story and problems were distributed online and were followed by in-class discussions and lab work. Aspects of the activity required independent thinking, as well as collaborative work. Student learning gains were demonstrated via comparison of pre- and postscores on the Host Pathogen Interactions (HPI concept inventory, results from an end of semester Student Perception Survey, and from analysis of students’ work.

    The Germanwings Flight 9525 crash has brought the sensitive subject of airline pilot mental health to the forefront in aviation. Globally, 350 million people suffer from depression-a common mental disorder. This study provides further information on this important topic regarding mental health especially among female airline pilots. This is the first study to describe airline pilot mental health-with a focus on depression and suicidal thoughts-outside of the information derived from aircraft accident investigations, regulated health examinations, or identifiable self-reports, which are records protected by civil aviation authorities and airline companies. This is a descriptive cross-sectional study via an anonymous web-based survey administered between April and December 2015. Pilots were recruited from unions, airline companies, and airports via convenience sampling. Data analysis included calculating absolute number and prevalence of health characteristics and depression scores. One thousand eight hundred thirty seven (52.7%) of the 3485 surveyed pilots completed the survey, with 1866 (53.5%) completing at least half of the survey. 233 (12.6%) of 1848 airline pilots responding to the Patient Health Questionnaire 9 (PHQ-9), and 193 (13.5%) of 1430 pilots who reported working as an airline pilot in the last seven days at time of survey, met depression threshold-PHQ-9 total score ≥ 10. Seventy-five participants (4.1%) reported having suicidal thoughts within the past two weeks. We found a significant trend in proportions of depression at higher levels of use of sleep-aid medication (trend test z = 6.74, p < 0.001) and among those experiencing sexual harassment (z = 3.18, p = 0.001) or verbal harassment (z = 6.13, p < 0.001). Hundreds of pilots currently flying are managing depressive symptoms perhaps without the possibility of treatment due to the fear of negative career impacts. This study found 233 (12.6%) airline pilots meeting

    We present 23 new Brown Dwarf (BD) candidates from the Multi-object APO Radial-Velocity Exoplanet Large-Area Survey (MARVELS) of the Sloan Digital Sky Survey III (SDSS-III). The BD candidates were selected from the processed MARVELS data using the latest University of Florida 2D pipeline, which shows significant improvement and reduction of systematic errors over the 1D pipeline results included in the SDSS Data Release 12. This sample is the largest BD yield from a single radial velocity survey. Of the 23 candidates, 18 are around main sequence stars and 5 are around giant stars. Given a giant contamination rate of ~24% for the MARVELS survey, we find a BD occurrence rate around main sequence stars of ~0.7%, which agrees with previous studies and confirms the BD desert, while the BD occurrence rate around the MARVELS giant stars is ~0.6%. Preliminary results show that our new candidates around solar type stars support a two population hypothesis, where BDs are divided at a mass of ~42.5 MJup. BDs less massive than 42.5 MJup have eccentricity distributions consistent with planet-planet scattering models, where BDs more massive than 42.5 MJup have both period and eccentricity distributions similar to that of stellar binaries. Special Brown Dwarf systems such as multiple BD systems and highly eccentric BDs will also be presented.

  4. Camera trap arrays improve detection probability of wildlife: Investigating study design considerations using an empirical dataset.

    Directory of Open Access Journals (Sweden)

    Kelly M O'Connor

    Full Text Available Camera trapping is a standard tool in ecological research and wildlife conservation. Study designs, particularly for small-bodied or cryptic wildlife species often attempt to boost low detection probabilities by using non-random camera placement or baited cameras, which may bias data, or incorrectly estimate detection and occupancy. We investigated the ability of non-baited, multi-camera arrays to increase detection probabilities of wildlife. Study design components were evaluated for their influence on wildlife detectability by iteratively parsing an empirical dataset (1 by different sizes of camera arrays deployed (1-10 cameras, and (2 by total season length (1-365 days. Four species from our dataset that represented a range of body sizes and differing degrees of presumed detectability based on life history traits were investigated: white-tailed deer (Odocoileus virginianus, bobcat (Lynx rufus, raccoon (Procyon lotor, and Virginia opossum (Didelphis virginiana. For all species, increasing from a single camera to a multi-camera array significantly improved detection probability across the range of season lengths and number of study sites evaluated. The use of a two camera array increased survey detection an average of 80% (range 40-128% from the detection probability of a single camera across the four species. Species that were detected infrequently benefited most from a multiple-camera array, where the addition of up to eight cameras produced significant increases in detectability. However, for species detected at high frequencies, single cameras produced a season-long (i.e, the length of time over which cameras are deployed and actively monitored detectability greater than 0.75. These results highlight the need for researchers to be critical about camera trap study designs based on their intended target species, as detectability for each focal species responded differently to array size and season length. We suggest that researchers a priori

    The Pneumonia Etiology Research for Child Health (PERCH) project is the largest multicountry etiology study of childhood pneumonia since the Board on Science and Technology in International Development studies of the 1980s. However, it is not the only recent or ongoing pneumonia etiology study, and even with seven sites, it cannot capture all epidemiologic settings in the developing world. Funding providers, researchers and policymakers rely on the best available evidence to strategically plan programs, new research directions and interventions. We aimed to describe the current landscape of recent pneumonia etiology studies in children under 5 years of age in the developed and developing world, as ascertained by a literature review of relevant studies with data since the year 2000 and a survey of researchers in the field of childhood pneumonia. We collected information on the study population, study design, case definitions, laboratory samples and methods and identified pathogens. A literature review identified 88 studies with child pneumonia etiology results. As of June 2010, our survey of researchers identified an additional 65 ongoing and recently completed child pneumonia etiology studies. This demonstrates the broad existing context into which the PERCH study must be placed. However, the landscape analysis also reveals a multiplicity of case definitions, levels of clinician involvement, facility types, specimen collection, and laboratory techniques. It reinforces the need for the standardization of methods and analyses for present and future pneumonia etiology studies in order to optimize their cumulative potential to accurately describe the microbial causes of childhood pneumonia.

    The underrepresentation of women in science, technology, engineering, and mathematics (STEM)-related fields remains a concern for educators and the scientific community. Gender differences in mathematics and science achievement play a role, in conjunction with attitudes and self-efficacy beliefs. We report results from the 2011 Trends in Mathematics and Science Study (TIMSS), a large international assessment of eighth grade students' achievement, attitudes, and beliefs among 45 participating nations (N = 261,738). Small- to medium-sized gender differences were found for most individual nations (from d = -.60 to +.31 in mathematics achievement, and d = -.60 to +.26 for science achievement), although the direction varied and there were no global gender differences overall. Such a pattern cross-culturally is incompatible with the notion of immutable gender differences. Additionally, there were different patterns between OECD and non-OECD nations, with girls scoring higher than boys in mathematics and science achievement across non-OECD nations. An association was found between gender differences in science achievement and national levels of gender equality, providing support for the gender segregation hypothesis. Furthermore, the performance of boys was more variable than that of girls in most nations, consistent with the greater male variability hypothesis. Boys reported more favorable attitudes towards mathematics and science, and girls reported lower self-efficacy beliefs. While the gender gap in STEM achievement may be closing, there are still large sections of the world where differences remain.

    Full Text Available This paper presents an investigation into how students studying at university engage actively with learning technology in their self-directed study time. The case study surveyed 250 students studying at undergraduate and postgraduate level from a purposive sample of departments within one institution. The study has also conducted focus groups and a number of in-depth follow-up interviews with respondents to the survey. In this article we explore three emerging aspects of the learning experience, namely student expectations of the technology, their lecturers' engagement with technology and how the technology might support processes of transition in higher education. One key implication is that more academic guidance is needed on what and how to use the technology effectively for independent learning, even where ICT skills levels are high. The study also identifies the significant role that the lecturer plays in facilitating students' use of technology. The findings of this study will be of interest to those working to incorporate learning technologies more effectively in higher education, in particular for those who are looking to improve the engagement of students in self-directed learning.

    There has been little progress in adolescent health outcomes in recent decades. Researchers and youth-serving organizations struggle to accurately elicit youth voice and translate youth perspectives into health care policy. Our aim is to describe the protocol of the MyVoice Project, a longitudinal mixed methods study designed to engage youth, particularly those not typically included in research. Text messaging surveys are collected, analyzed, and disseminated in real time to leverage youth perspectives to impact policy. Youth aged 14 to 24 years are recruited to receive weekly text message surveys on a variety of policy and health topics. The research team, including academic researchers, methodologists, and youth, develop questions through an iterative writing and piloting process. Question topics are elicited from community organizations, researchers, and policy makers to inform salient policies. A youth-centered interactive platform has been developed that automatically sends confidential weekly surveys and incentives to participants. Parental consent is not required because the survey is of minimal risk to participants. Recruitment occurs online (eg, Facebook, Instagram, university health research website) and in person at community events. Weekly surveys collect both quantitative and qualitative data. Quantitative data are analyzed using descriptive statistics. Qualitative data are quickly analyzed using natural language processing and traditional qualitative methods. Mixed methods integration and analysis supports a more in-depth understanding of the research questions. We are currently recruiting and enrolling participants through in-person and online strategies. Question development, weekly data collection, data analysis, and dissemination are in progress. MyVoice quickly ascertains the thoughts and opinions of youth in real time using a widespread, readily available technology-text messaging. Results are disseminated to researchers, policy makers, and

    Directory of Open Access Journals (Sweden)

    Gerda de Klerk

    2008-01-01

    Full Text Available This article is a response to Mark Pfeifer’s Cambodian, Hmong, Lao and Vietnamese Americans in the 2005 American Community Survey and elaborates on the utility of the American Community Survey (ACS for studying immigrant groups in the United States of America, and also compares the ACS to the U.S. Census. Neither the Census nor ACS questionnaire is structured to capture the language and literacy skills of immigrant communities in as far as these surveys only collect information about respondents’ oral language abilities, with a focus on English fluency. Direct, self-reported, and surrogate measures of literacy are discussed, with a proposal to use education level as surrogate for literacy. Using the Vietnamese subpopulation in the ACS, examples are presented of ways to construct composite variables from the ACS raw microdata, to measure respondents’ bilingualism and biliteracy. When such new variables are used in analysis of immigrant communities, a more complex multilingual picture emerges than is presented normally in Census and ACS data products available to the public.

    The objective of this study is to present data from a roadside survey study on drinking and driving and alcohol consumption in southeastern Brazil. A cross-sectional roadside survey study using a questionnaire and breathalyzer data is the method used to determine the prevalence of drinking and driving and to examine whether socio-demographic characteristics and drivers' behavior, attitude and alcohol consumption predicted positive blood alcohol content (BAC). The data were gathered from 2005 to 2007 through roadside surveys conducted on high volume public roads in four cities in southeastern Brazil. A total of 4182 randomly selected drivers took part in the research. Of these drivers, 3488 (83.4%) completed the questionnaire and agreed to take a breath test. Overall, 24.6% of drivers had a detectable blood alcohol concentration (BAC) and 15.9% had a BAC above the legal limit (0.6g/l) at the time of the study. Logistic regression controlling for locale (city), sex, age and marital status was used to predict whether each driver would present a positive breath test. Socio-demographic characteristics, driving behaviors and attitudes, and alcohol consumption patterns were included as predictors. These analyses indicated that those who believed drinking and driving was a serious offense were about two-thirds as likely to have a positive breath test, and that drivers reporting a pattern of regular alcohol use were three times as likely to have a positive breath test. These findings indicate that drinking and driving is relatively common in Brazil, and that it occurs considerably more frequently than similar surveys suggest, is the case in other countries.

    Clinical nurse leader (CNL)-integrated care delivery is an emerging nursing model, with growing adoption in diverse health systems. To generate a robust evidence base for this promising nursing model, it is necessary to measure CNL practice to explicitly link it to observed quality and safety outcome improvements. This study used a modified Delphi approach with an expert CNL panel to develop and test the face, content, and construct validity of the CNL Practice Survey instrument.

  1. New Mission Concept Study: Energetic X-Ray Imaging Survey Telescope (EXIST)

    Science.gov (United States)

    1998-01-01

    This Report summarizes the activity carried out under the New Mission Concept (NMC) study for a mission to conduct a sensitive all-sky imaging survey in the hard x-ray (HX) band (approximately 10-600 keV). The Energetic X-ray Imaging Survey Telescope (EXIST) mission was originally proposed for this NMC study and was then subsequently proposed for a MIDEX mission as part of this study effort. Development of the EXIST (and related) concepts continues for a future flight proposal. The hard x-ray band (approximately 10-600 keV) is nearly the final band of the astronomical spectrum still without a sensitive imaging all-sky survey. This is despite the enormous potential of this band to address a wide range of fundamental and timely objectives - from the origin and physical mechanisms of cosmological gamma-ray bursts (GRBs) to the processes on strongly magnetic neutron stars that produce soft gamma-repeaters and bursting pulsars; from the study of active galactic nuclei (AGN) and quasars to the origin and evolution of the hard x-ray diffuse background; from the nature and number of black holes and neutron stars and the accretion processes onto them to the extreme non-thermal flares of normal stars; and from searches for expected diffuse (but relatively compact) nuclear line (Ti-44) emission in uncatalogued supernova remnants to diffuse non-thermal inverse Compton emission from galaxy clusters. A high sensitivity all-sky survey mission in the hard x-ray band, with imaging to both address source confusion and time-variable background radiations, is very much needed.

    1997-12-31

    This is the final report from the PIAC project, which was a multidisciplinary survey on acid rain in China. One goal was to document effects of airborne acidifying compounds on vegetation, soil, soil- and surface-water and aquatic biota. Other goals were to exchange knowledge between Chinese and Norwegian scientists, and to visit research sites in highly polluted areas in China and evaluate their need of support in a future collaborative monitoring and research programme. Samples have been collected from over 20 sites in three areas. Negative effects of air pollution are found on all ecosystem levels investigated. The concentration of sulfur in the air in urban and near-urban areas is very high. The concentration of volatile organic compounds is generally high, which means that increased NOx emissions in coming years may increase the ozone problems. Reduced photosynthesis activities were found in some plants and acidification observed in soil and surface water. Aquatic biota also reflect the acidification status of the surface waters investigated. However, it is difficult to assess the degree of damage in these regions because the survey includes too few sites. Surface water acidification is currently not a major environmental problem in China and is unlikely to be one during the next decades. The report includes a status report on acidification in China and a proposed framework for a monitoring programme based on Norwegian experiences. 139 refs., 16 figs., 45 tabs.

    Because of observed clinical variance and the discretion of referring physicians and radiologists in patient follow-up, the purpose of this study was to conduct a survey to explore whether broad discrepancy exists in imaging protocols used for postsurgical surveillance. An online survey was created to assess radiologists' use of diagnostic versus screening mammography for women with a personal history of breast cancer and determine whether the choice of protocol was associated with practice characteristics (setting, region, and reader type). Of 8170 surveys sent, 849 (10%) completed responses were returned. Seventy-nine percent of respondents recommended initial diagnostic mammography after lumpectomy (65% at 6 months, 14% at 12 months); 49% recommended diagnostic surveillance for up to 2 years before a return to screening mammography; and 33% continued diagnostic surveillance for 2-5 years before returning to screening. For imaging after mastectomy, 57% of respondents recommended diagnostic mammography of the unaffected breast. Among the 57%, however, 37% recommended diagnostic screening for only the first postmastectomy follow-up evaluation, and the other 20% permanently designated patients for diagnostic mammography after mastectomy. The optimal surveillance mammography regimen must be better defined. This preliminary study showed variability in diagnostic versus screening surveillance mammography for women with a history of breast cancer. Future studies should evaluate why these variations occur and how to standardize recommendations to tailor personalized imaging.

    Thickness estimation of sedimentary basin is a complex geological problem, especially in an orogenic environment. Intense and multiple tectonic movements and climate changes result in inhomogeneity of sedimentary layers and basement configurations, which making sedimentary structure modelling difficult. In this study, integrated geophysical methods, including gravity, magnetotelluric (MT) sounding and electrical resistivity tomography (ERT), were used to estimate basement relief to understand the geological structure and evolution of the eastern Barkol Basin in China. This basin formed with the uplift of the eastern Tianshan during the Cenozoic. Gravity anomaly map revealed the framework of the entire area, and ERT as well as MT sections reflected the geoelectric features of the Cenozoic two-layer distribution. Therefore, gravity data, constrained by MT, ERT and boreholes, were utilized to estimate the spatial distribution of the Quaternary layer. The gravity effect of the Quaternary layer related to the Tertiary layer was later subtracted to obtain the residual anomaly for inversion. For the Tertiary layer, the study area was divided into several parts because of lateral difference of density contrasts. Gravity data were interpreted to determine the density contrast constrained by the MT results. The basement relief can be verified by geological investigation, including the uplift process and regional tectonic setting. The agreement between geophysical survey and prior information from geology emphasizes the importance of integrated geophysical survey as a complementary means of geological studies in this region.

    The Surgeons OverSeas assessment of surgical need (SOSAS) tool, a population-based survey on surgical conditions in low- and middle-income countries (LMICs), was performed in Sierra Leone and Rwanda. This pilot study in Nepal is the initial implementation of the SOSAS survey in South Asia. A pilot study of SOSAS, modified for Nepal's needs and reprogrammed using mobile data collection software, was undertaken in Pokhara in January 2014. Cluster randomized sampling was utilized to interview 100 individuals in 50 households within two wards of Pokhara, one rural and one urban. The first portion of the survey retrieved demographic data, including household members and time to nearest health facilities. The second portion interviewed two randomly selected individuals from each household, inquiring about surgical conditions covering six anatomical regions. The pilot SOSAS in Nepal was easily completed over 3 days, including training of 18 Nepali interns over 2 days. The response rate was 100 %. A total of 13 respondents had a current surgical need (face 4, chest 1, back 1, abdomen 1, groin 3, extremity 3), although eight reported there was no need for surgical care. Five respondents (5 %) had a current unmet surgical need. The SOSAS pilot study in Nepal was successfully conducted, demonstrating the feasibility of performing SOSAS in South Asia. The estimated 5 % current unmet surgical need will be used for sample size calculation for the full country survey. Utilizing and improving on the SOSAS tool to measure the prevalence of surgical conditions in Nepal will help enumerate the global surgical burden of disease.

    Full Text Available Abstract Background Schistosomiasis and soil-transmitted helminthiasis (STHs are target neglected tropical diseases (NTDs of preventive chemotherapy, but the control and elimination of these diseases have been impeded due to resource constraints. Few reports have described study protocol to draw on when conducting a nationwide survey. We present a detailed methodological description of the integrated mapping of schistosomiasis and STHs on the basis of our experiences, hoping that this protocol can be applied to future surveys in similar settings. In addition to determining the ecological zones requiring mass drug administration interventions, we aim to provide precise estimates of the prevalence of these diseases. Methods A school–based cross-sectional design will be applied for the nationwide survey across Sudan. The survey is designed to cover all districts in every state. We have divided each district into 3 different ecological zones depending on proximity to bodies of water. We will employ a probability-proportional-to-size sampling method for schools and systematic sampling for student selection to provide adequate data regarding the prevalence for schistosomiasis and STHs in Sudan at the state level. A total of 108,660 students will be selected from 1811 schools across Sudan. After the survey is completed, 391 ecological zones will be mapped out. To carry out the survey, 655 staff members were recruited. The feces and urine samples are microscopically examined by the Kato-Katz method and the sediment smears for helminth eggs respectively. For quality control, a minimum of 10% of the slides will be rechecked by the federal supervisors in each state and also 5% of the smears are validated again within one day by independent supervisors. Discussion This nationwide mapping is expected to generate important epidemiological information and indicators about schistosomiasis and STHs that will be useful for monitoring and evaluating the control

    The X-Ray Surveyor mission concept is unique among those being studied for prioritization in the NASA Astrophysics 2020 Decadal Survey. The X-Ray Surveyor mission will explore the high-energy Universe; providing essential and complimentary observations to the Astronomy Community. The NASA Astrophysics Roadmap (Enduring Quests, Daring Visions) describes the need for an X-Ray Observatory that is capable of addressing topics such as the origin and growth of the first supermassive black holes, galaxy evolution and growth of the cosmic structure, and the origin and evolution of the stars that make up our Universe. To address these scientifically compelling topics and more, an Observatory that exhibits leaps in capability over that of previous X-Ray Observatories in needed. This paper describes the current status of the X-Ray Surveyor Mission Concept Study and the path forward, which includes scientific investigations, technology development, and community participation.

    Full Text Available Papandayan volcano located in the southern part of Garut regency, around 70 km away from Bandung city, West Java. Many methods carried out to monitoring the activities of volcano, both continuously or periodically, one of the monitoring method is periodically GPS survey. Basically those surveys are carried out to understand the pattern and velocity of displacement which occurred in the volcano body, both horizontally and vertically, and also others deformation elements such as; translation, rotation and dilatation. The Mogi modeling was also used to determine the location and volume of the pressure source which caused deformation of volcano body. By comparing seismic activity and the deformation reveal from GPS measurement, before, during and after eruption, it could be understood there is a correlation between the seismicity and its deformation. These studies is hoping that GPS measurement in Papandayan volcano could be one of supported method to determine the volcano activities, at least in Papandayan volcano.

    1993-09-24

    During 1992, the Energy Information Administration (EIA) conducted a user-needs study for the 1993 Residential Energy Consumption Survey (RECS). Every 3 years, the RECS collects information on energy consumption and expenditures for various classes of households and residential buildings. The RECS is the only source of such information within EIA, and one of only a few sources of such information anywhere. EIA sent letters to more than 750 persons, received responses from 56, and held 15 meetings with users. Written responses were also solicited by notices published in the April 14, 1992 Federal Register and in several energy-related publications. To ensure that the 1993 RECS meets current information needs, EIA made a specific effort to get input from policy makers and persons needing data for forecasting efforts. These particular needs relate mainly to development of the National Energy Modeling System and new energy legislation being considered at the time of the user needs survey.

    Full Text Available Abstract Background The data from longitudinal complex surveys based on multi-stage sampling designs contain cross-sectional dependencies among units due to clustered nature of the data and within-subject dependencies due to repeated measurements. Special statistical methods are required to analyze longitudinal complex survey data. Methods Statistics Canada's longitudinal National Population Health Survey (NPHS dataset from the first five cycles (1994/1995 to 2002/2003 was used to investigate the effects of demographic, social, life-style, and health-related factors on the longitudinal changes of mental distress scores among the NPHS participants who self-reported physician diagnosed respiratory diseases, specifically asthma and chronic bronchitis. The NPHS longitudinal sample includes 17,276 persons of all ages. In this report, participants 15 years and older (n = 14,713 were considered for statistical analysis. Mental distress, an ordinal outcome variable (categories: no/low, moderate, and high was examined. Ordered logistic regression models based on the weighted generalized estimating equations approach were fitted to investigate the association between respiratory diseases and mental distress adjusting for other covariates of interest. Variance estimates of regression coefficients were computed by using bootstrap methods. The final model was used to predict the probabilities of prevalence of no/low, moderate or high mental distress scores. Results Accounting for design effects does not vary the significance of the coefficients of the model. Participants suffering with chronic bronchitis were significantly at a higher risk (ORadj = 1.37; 95% CI: 1.12-1.66 of reporting high levels of mental distress compared to those who did not self-report chronic bronchitis. There was no significant association between asthma and mental distress. There was a significant interaction between sex and self-perceived general health status indicating a dose

    2007-07-01

    Full Text Available Abstract Background The objective of the present study was to compare three different sampling and questionnaire administration methods used in the international KIDSCREEN study in terms of participation, response rates, and external validity. Methods Children and adolescents aged 8–18 years were surveyed in 13 European countries using either telephone sampling and mail administration, random sampling of school listings followed by classroom or mail administration, or multistage random sampling of communities and households with self-administration of the survey materials at home. Cooperation, completion, and response rates were compared across countries and survey methods. Data on non-respondents was collected in 8 countries. The population fraction (PF, respondents in each sex-age, or educational level category, divided by the population in the same category from Eurostat census data and population fraction ratio (PFR, ratio of PF and their corresponding 95% confidence intervals were used to analyze differences by country between the KIDSCREEN samples and a reference Eurostat population. Results Response rates by country ranged from 18.9% to 91.2%. Response rates were highest in the school-based surveys (69.0%–91.2%. Sample proportions by age and gender were similar to the reference Eurostat population in most countries, although boys and adolescents were slightly underrepresented (PFR Conclusion School-based sampling achieved the highest overall response rates but also produced slightly more biased samples than the other methods. The results suggest that the samples were sufficiently representative to provide reference population values for the KIDSCREEN instrument.

    Minority children with asthma who live in low-income urban communities bear a disproportionate burden of the disease. This study explores the perceived health care needs related to asthma care, identifies asthma triggers, potential barriers to care, and assesses the need for additional community resources. We conducted a cross-sectional survey of Hispanic and African American adults (n = 53) who take care of a child with asthma and live in an urban community of North Philadelphia. Input from community leaders was obtained in the development the survey tool resulting in a unique 'community-centric' questionnaire. The survey was also available in Spanish. All surveys were conducted in the community setting. Variables were used to measure asthma severity and triggers. Children were categorized with intermittent (n = 24, 45.3%), mild persistent (n = 13, 24.5%), or moderate-to-severe persistent asthma (n = 16, 30.2%). Most children with persistent asthma were enrolled under Medicaid or CHIP (n = 24, p = 0.011) and reflected a low-income socioeconomic status. Persistent asthma was found to be associated with most triggers: pets, dust mites, mice, mold, and cockroaches. There was no significant association between environmental tobacco smoke and persistent asthma. Children with persistent asthma and 2 or more triggers were more likely to be hospitalized and go to the Emergency Department. Urban minority children living in low-income communities face neighborhood-specific asthma triggers and challenges to care. Studies conducted in urban neighborhoods, with collaboration from community members, will highlight the need of comprehensive services to account for community-centric social determinants.

    The psychiatric epidemiological population study NEMESIS-2 (Netherlands Mental Health Survey and Incidence Study-2) replicates and expands the first Netherlands Mental Health Survey and Incidence Study (NEMESIS-1) conducted from 1996 to 1999. The main objectives of the new study are to provide up-to-date figures on the prevalence, incidence, course and consequences of mental disorders, and to study trends in mental disorders and service use, with the use of a new sample. New topics not included in NEMESIS-1 were added, e.g. impulse-control disorders, and genetic correlates of mental disorders through gathering DNA from saliva samples. This paper gives an overview of the design of NEMESIS-2, especially of its recently completed first wave. NEMESIS-2 is a prospective study among Dutch-speaking subjects aged 18-64 years from the general Dutch population. Its baseline wave included 6646 subjects. Three waves are planned with three year-intervals between the waves. A multistage, stratified random sampling procedure was applied. The baseline wave of NEMESIS-2 was performed between November 2007 and July 2009. Face-to-face interviews were administered with the Composite International Diagnostic Interview (CIDI) 3.0. The response rate was 65.1%, and 76.4% of the respondents donated saliva. The sample was reasonably nationally representative, but younger subjects were somewhat underrepresented. In conclusion, we were able to build a comprehensive dataset of good quality, permitting several topics to be studied in the future.

    Full Text Available Abstract Background In Ethiopia, information regarding highland malaria transmission is scarce, and no report has been presented from Butajira highland so far whether the appearance of malaria in the area was due to endemicity or due to highland malaria transmission. Thus this study aimed to determine the presence and magnitude of malaria transmission in Butajira. Methods For parasitological survey, longitudinal study was conducted from October to December 2006. The entomological surveys were done from October to December 2006 and continued from April to May 2007. Both parasitological and entomological surveys were done using standard procedures. Results The parasitological result in all the survey months (October-December showed an overall detection rate of 4.4% (48/1082 (CI 95%; 3.2-5.7% malaria parasite. Among infected individuals, 32 (3.0% of the infection was due to Plasmodium vivax and the rest 16 (1.5% were due to Plasmodium falciparum. The highest prevalence 39(3.6% of the parasite was observed in age groups of above 15 years old. Among the total tested, 25(2.3% of males and 23(2.1% of females had malaria infection. Among tested individuals, 38(5.3% and 10 (2.7% of infection was occurred in Misrak-Meskan (2100 m a.s.l and Mirab-Meskan (2280 m a.s.l, respectively which was statistically significant (X2 = 3.72, P Plasmodium species declined from October to December, the trend was non-significant (X2 for trend = 0.49, P > 0.05. The entomological survey showed a collection of 602 larvae and 80 adult Anopheles. Anopheles christyi was the dominant species both in the first (45.3% and in the second (35.4% surveys; where as, Anopheles gambiae sensu lato comprised 4.7% and 14.6%, in the first and second surveys, respectively. Anopheles gambiae s.l comprises 55% of the adult collection, and both species were collected more from outdoors (57.5%. The number of An. christyi was higher in Mirab-Meskan (58. 3% than Misrak-Meskan (41.7% (P Conclusion

    At the request of the U.S. Forest Service, an instream flow assessment was conducted at Cherry Creek, Ariz., to investigate habitat for native and introduced fish species and to describe the beneficial use of a possible instream flow water right. The U.S. Geological Survey (USGS) Fort Collins Science Center performed an intensive field study of two sections of Cherry Creek in September 2008 to provide base data for hydrodynamic simulation of the flow conditions in the stream. The USGS Arizona Cooperative Fish and Wildlife Research Unit, at the University of Arizona School of Natural Resources, conducted a survey of the habitat requirements of the resident fish species in Cherry Creek and provided the habitat suitability criteria used in this study. The habitat suitability criteria were combined with hydrodynamic simulation results to quantify fish habitat for the full range of daily flow experienced in the creek and to produce maps of habitat occurrence for those flows. The flow record at the Cherry Creek stream gage was used to generate habitat response values over time. The long-term habitat response was incorporated into an Excel (Registered) spreadsheet to allow evaluation of habitat occurrence with and without an instream water right under different hypothetical water withdrawal scenarios. The spreadsheet displays information about the time sequence of habitat events, the duration of critical events, and habitat retention.

    In this study, we integrated a DNA barcoding project with an ecological survey on intertidal polychaete communities and investigated the utility of CO1 gene sequence as a DNA barcode for the classification of the intertidal polychaetes. Using 16S rDNA as a complementary marker and combining morphological and ecological characterization, some of dominant and common polychaete species from Chinese coasts were assessed for their taxonomic status. We obtained 22 haplotype gene sequences of 13 taxa, including 10 CO1 sequences and 12 16S rDNA sequences. Based on intra- and inter-specific distances, we built phylogenetic trees using the neighbor-joining method. Our study suggested that the mitochondrial CO1 gene was a valid DNA barcoding marker for species identification in polychaetes, but other genes, such as 16S rDNA, could be used as a complementary genetic marker. For more accurate species identification and effective testing of species hypothesis, DNA barcoding should be incorporated with morphological, ecological, biogeographical, and phylogenetic information. The application of DNA barcoding and molecular identification in the ecological survey on the intertidal polychaete communities demonstrated the feasibility of integrating DNA taxonomy and ecology.

    Reliable and comparable information on households with catastrophic health expenditure (HCHE) is crucial for monitoring and evaluating our progress towards achieving universal financial risk protection. This study aims to investigate the sensitivity of measuring the progress in financial risk protection to survey design and its socioeconomic and demographic determinants. Using the Rwanda Integrated Living Conditions Survey in 2005 and 2010/2011, we derived the level and trend of the percentage of the HCHE using out-of-pocket health spending data derived from (1) a health module with a two-week recall period and six (2005)/seven (2010/2011) survey questions (Method 1) and (2) a consumption module with a four-week/ten-/12-month recall period and 11(2005)/24 (2010/2011) questions (Method 2). Using multilevel logistic regression analysis, we investigated the household socioeconomic and demographic characteristics that affected the sensitivity of estimating the HCHE to survey design. We found that Method 1 generated a significantly higher HCHE estimate (9.2%, 95% confidence interval 8.4%-10.0%) than Method2 (7.4%, 6.6%-8.1%) in 2005 and lower estimate (5.6%, 5.2%-6.1%) than Method 2 (8.2%, 7.6%-8.7%) in 2010/2011. The estimated trends of the HCHE using the two methods were not consistent between the two years. A household's size, its income quintile, having no under-five children, and educational level of its head were positively associated with the consistency of its HCHE status when using the two survey methods. Estimates of the progress in financial risk protection, especially among the most vulnerable households, are sensitive to survey design. These results are robust to various thresholds of catastrophic health spending. Future work must focus on mitigating survey effects through the development of statistical tools.

    The development of close-range photogrammetry has produced a lot of new possibility to study cultural heritage. 3D data acquired with conventional and low cost cameras can be used to document, investigate the full appearance, materials and conservation status, to help the restoration process and identify intervention priorities. At the same time, with 3D survey a lot of three-dimensional data are collected and analyzed by researchers, but there are a very few possibility of 3D output. The augmented reality is one of this possible output with a very low cost technology but a very interesting result. Using simple mobile technology (for iPad and Android Tablets) and shareware software (in the case presented "Augment") it is possible to share and visualize a large number of 3D models with your own device. The case study presented is a part of an architecture graduate thesis, made in Rome at Department of Architecture of Roma Tre University. We have developed a photogrammetric survey to study the Aurelian Wall at Castra Praetoria in Rome. The surveys of 8000 square meters of surface have allowed to identify stratigraphy and construction phases of a complex portion of Aurelian Wall, specially about the Northern door of Castra. During this study, the data coming out of 3D survey (photogrammetric and topographic), are stored and used to create a reverse 3D model, or virtual reconstruction, of the Northern door of Castra. This virtual reconstruction shows the door in the Tiberian period, nowadays it's totally hidden by a curtain wall but, little and significative architectural details allow to know its original feature. The 3D model of the ancient walls has been mapped with the exact type of bricks and mortar, oriented and scaled according to the existing one to use augmented reality. Finally, two kind of application have been developed, one on site, were you can see superimposed the virtual reconstruction on the existing walls using the image recognition. On the other hand

    Full Text Available Survey data collection projects strive to collect high quality data from survey respondents. The quality of the data collected is greatly dependent upon the effectiveness of field interviewers (FIs to conduct inperson screenings and interviews. Training FIs and subsequently assessing their knowledge of project protocol, methods and interviewing techniques is critical to the overall success of any data collection effort. For large surveys, as the number of FIs increase, the cost of inperson training can become prohibitively large. As a cost effective solution to increase the quality of the field data, we developed a suite of web and media based training and assessment tools called iLearning and eHomeStudy for training field staff. Besides saving the project costs associated with inperson training, we are also able to provide refresher trainings throughout the year. This application also enables FIs to view standardized training courses at their convenience and at their own pace. This paper describes the technical details, key features and benefits of this application suite, and also it includes some details on user satisfaction and future directions.

    Full Text Available In areas of declining malaria transmission such as in The Gambia, the identification of malaria infected individuals becomes increasingly harder. School surveys may be used to identify foci of malaria transmission in the community.The survey was carried out in May-June 2011, before the beginning of the malaria transmission season. Thirty two schools in the Upper River Region of The Gambia were selected with probability proportional to size; in each school approximately 100 children were randomly chosen for inclusion in the study. Each child had a finger prick blood sample collected for the determination of antimalarial antibodies by ELISA, malaria infection by microscopy and PCR, and for haemoglobin measurement. In addition, a simple questionnaire on socio-demographic variables and the use of insecticide-treated bed nets was completed. The cut-off for positivity for antimalarial antibodies was obtained using finite mixture models. The clustered nature of the data was taken into account in the analyses.A total of 3,277 children were included in the survey. The mean age was 10 years (SD = 2.7 [range 4-21], with males and females evenly distributed. The prevalence of malaria infection as determined by PCR was 13.6% (426/3124 [95% CI = 12.2-16.3] with marked variation between schools (range 3-25%, p<0.001, while the seroprevalence was 7.8% (234/2994 [95%CI = 6.4-9.8] for MSP119, 11.6% (364/2997 [95%CI = 9.4-14.5] for MSP2, and 20.0% (593/2973 [95% CI = 16.5-23.2 for AMA1. The prevalence of all the three antimalarial antibodies positive was 2.7% (79/2920.This survey shows that malaria prevalence and seroprevalence before the transmission season were highly heterogeneous.

    Haldorson, Marie [Statistics Sweden, Oerebro (Sweden)

    2000-03-01

    Statistics Sweden (SCB) has produced this report on behalf of the Swedish Nuclear Fuel and Waste Management Company (SKB), as part of the data to be used by SKB in conducting studies of potential sites. The report goes over the statistics obtainable from SCB in the form of registers and surveys. The purpose is to identify the variables that are available, and to specify their degree of geographical detail and the time series that are available. Chapter two describes the statistical registers available at SCB, registers that share the common feature that they provide total coverage, i.e. they contain all 'objects' of a given type, such as population, economic activities (e.g. from statements of employees' earnings provided to the tax authorities), vehicles, enterprises or real estate. SCB has exclusive responsibility for seven of the nine registers included in the chapter, while two registers are ordered by public authorities with statistical responsibilities. Chapter three describes statistical surveys that are conducted by SCB, with the exception of the National Forest Inventory, which is carried out by the Swedish University of Agricultural Sciences. In terms of geographical breakdown, the degree of detail in the surveys varies, but all provide some possibility of reporting data at lower than the national level. The level involved may be county, municipality, yield district, coastal district or category of enterprises, e.g. aquaculture. Six of the nine surveys included in the chapter have been ordered by public authorities with statistical responsibilities, while SCB has exclusive responsibility for the others. Chapter four presents an overview of the statistics on land use maintained by SCB. This chapter does not follow the same pattern as chapters two and three but instead gives a more general account. The conclusion can be drawn that there are good prospects that SKB can make use of SCB's data as background information or in other ways when

    2017-01-01

    Background Oncology is a rapidly evolving field with continuous advancements in the diagnosis and treatment of cancer. Therefore, it is important that medical students are provided with the knowledge and experience required to care for oncology patients and enable them to diagnose and manage toxicities of novel therapeutic agents. Objective This study was performed to understand the medical students’ perspective of the oncology education provided in universities across Australia and identify areas of education that could potentially be modified or improved to ultimately attract more students to a career in oncology. Methods This pilot cross-sectional study consisted of an 18-question survey that was submitted online to medical students in their final year and interns rotating to the Tamworth Hospital. Results The survey was completed by 94 fifth-year medical students and interns. Oncology was taught both theoretically and clinically for 68% (63/93) of participants, and 48% (44/92) had an exclusive oncology rotation. Both theoretical and clinical oncology assessments were conducted for only 21% (19/92) of participants. Overall, 42% (38/91) of participants were satisfied with their oncology education, and 78% (40/51) were dissatisfied with the number of oncology teaching hours. The importance of a career in oncology was rated as low by 46% (41/90) of participants. Conclusions This pilot study indicates that there are potential areas to improve oncology teaching in Australian universities. The majority of surveyed students were dissatisfied with the number of teaching hours they receive in oncology. More global assessment of students and/or interns from other Australian institutes may yield further useful information. PMID:29233799

    1997-09-01

    Large-scale mental health surveys have provided invaluable information regarding the prevalence of specific mental disorders and service use for mental health reasons. Unfortunately, because vast surveys conducted face to face are very costly, many countries and provinces do not embark upon this path of research, thus depriving themselves of a rich source of data useful for service planning. As an alternative, the authors undertook a telephone survey with a sample of 893 residents from a Montreal catchment area. Mental disorders were assessed by the Composite International Diagnostic Interview Simplified (CIDIS), an instrument especially designed to be used in mail or telephone surveys. Service utilization was measured by an instrument similar to those used in recent large Canadian or American surveys. The prevalence rate for any mental disorder was lower in this study than in some large-scale epidemiological surveys reviewed. This could be explained by methodological differences, such as number of disorders covered and period of reference. With regard to specific mental disorders, results appeared very similar to those of other studies. Concerning service utilization, rates tended to be higher than in other studies, and this finding could reflect real differences between Quebec and other Canadian provinces or the United States. Aside from being lower in cost, telephone surveys can yield results comparable to those obtained in large-scale epidemiological surveys conducted by means of face-to-face interviews.

The localities represent a series of geological settings of varying scale, from near surface paleokarst and glacial environments to large scale geological features such as fault zones, grabens and dolerite intrusions. The geophysical and geological methods deployed likewise represent both detailed small scale investigations such as Lidar, radar and geoelectric investigations on and near the surface, and seismic investigations covering larger areas to a depth of several kilometers. The overall aim for all the studies has been to better understand reservoir and cap rock/ice systems in a barren arctic desert characterized by a frozen ground that challenges common geophysical methods. The investigations undertaken in connection with this thesis cover several areas The first part addresses the Billefjorden fault zone (BFZ) with its eastern hanging wall classic rift-basin. This fault zone can be traced for more than 200 km as a lineament that runs almost the entire length of Spitsbergen, from Wijdefjorden in the north to Storfjorden in the south. The seismic data along with surface observations and Lidar scans illustrate the long and complicated history of the BFZ and associated basin, from the initial formation via linkage of reverse faults in the Devonian, through Carboniferous reactivation as a normal fault with adjacent rift-basin in an extensional tectonic regime, to finally Tertiary contraction seen as fault reactivation and basin inversion in connection with the formation of the west-coast fold and thrust-belt. Especially the development of the Carboniferous rift-basin is of interest. An integrated study by seismic and georadar mapping, and Lidar data interpretation combined with outcrop analysis of faults and sedimentary succession, have shed new, detailed information on the good sandstone

    I will discuss the results of the first survey in the planned longitudinal study of astronomy graduate students. Preliminary analyses show that women are: less likely to agree that the environment in the department is welcoming, more likely to believe they lack ability, and are less confident in their careers. These results also apply to men who have been in the program more than three years. Final results will be presented at the session. We are grateful for the financial support of AAS and for the sponsorship of CSWA.

    Many community hospital gynecologic surgery training programs now include robotics.At St. Francis Hospital and Medical Center, we have integrated robotic surgical training since 2006. This study is designed to assess the success in training gynecology residents in robotic surgery. An anonymous web-based survey tool (www. survey monkey. com) was sent to all Ob/Gyn residency graduates from 2007-2010 (n = 17). From 2011-2014, we emailed three reevaluation questions to all 2007-2014 graduates (N = 32). Design Classification: II-3. The response rate was 95%, and 11 of 17 initial graduates (65%) indicated that they had received adequate robotic training. Currently, 24 of 32 (75%) graduates practice in hospitals with robotic availability. Twenty of the 32 graduates (63%) are using robotics in their surgical practices. Nine of these 20 graduates (45%) were fully credentialed following their residency. The other 11 graduates (55%)required further proctoring to obtain full robotic credentials. Robotic surgical training is a component of modern gynecologic surgical training. Postresidency robotic credentialing is a realistic graduation goal for residents who plan to practice gynecologic surgery.

    This Feasibility Study (FS) report for the Badger Army Ammunition Plant (BAAP) in Baraboo, Wisconsin, was prepared by ABB Environmental Services, Inc. (ABB-ES) as a component of Task Order 1 of Contract DAAAl5-91-D-OOO8 with the U.S. Army Environmental Center (USAEC). This report uses the results presented in the Final Remedial Investigation (RI) report (ABB-ES, 1993a) to develop and screen alternatives for remediation of contaminated media at BAAP. The purpose of this FS report is to develop, screen, and evaluate site-specific remedial alternatives to mitigate the impact of site-derived chemicals and ultimately provide protection of human health and the environment. Preferred alternatives for each site are included in this report. Based on previous environmental studies at BAAP, 11 potential hazardous waste sites were ranked according to potential contributions of hazardous chemicals to the environment. These sites were designated as Waste Management Areas because some of the sites contain multiple Solid Waste Management Units (SWMUs). The sites selected to undergo facility assessment and corrective actions are: the Propellant Burning Ground (including Landfill), Deterrent Burning Ground, existing Landfill, Settling Ponds and Spoils Disposal Area, Rocket Paste Area, Oleum Plant and Oleum Plant Pond, Nitroglycerine Pond, old Acid Area, new Acid Area, and Ballistics Pond. The USAEC added an 11th site, the Old Fuel Oil Tank, to the list in October 1989 after discovery of fuel-contaminated soils during excavation of a water line in the vicinity of the old fuel oil tank foundation.

  10. 'Asking the Right Question'. A Comparison of Two Approaches to Gathering Data on 'Herbals' Use in Survey Based Studies.

    Directory of Open Access Journals (Sweden)

    James S McLay

    Full Text Available Over the last decade academic interest in the prevalence and nature of herbal medicines use by pregnant women has increased significantly. Such data are usually collected by means of an administered questionnaire survey, however a key methodological limitation using this approach is the need to clearly define the scope of 'herbals' to be investigated. The majority of published studies in this area neither define 'herbals' nor provide a detailed checklist naming specific 'herbals' and CAM modalities, which limits inter-study comparison, generalisability and the potential for meta-analyses. The aim of this study was to compare the self-reported use of herbs, herbal medicines and herbal products using two different approaches implemented in succession.Cross-sectional questionnaire surveys of women attending for their mid-trimester scan or attending the postnatal unit following live birth at the Royal Aberdeen Maternity Hospital, North-East Scotland. The questionnaire utilised two approaches to collect data on 'herbals' use, a single closed yes/no answer to the question "have you used herbs, herbal medicines and herbal products in the last three months"; and a request to tick which of a list of 40 'herbals' they had used in the same time period.A total of 889 responses were obtained of which 4.3% (38 answered 'yes' to herbal use via the closed question. However, using the checklist 39% (350 of respondents reported the use of one or more specific 'herbals' (p<0.0001. The 312 respondents who reported 'no' to 'herbals' use via the closed question but "yes" via the checklist consumed a total of 20 different 'herbals' (median 1, interquartile range 1-2, range 1-6.This study demonstrates that the use of a single closed question asking about the use of 'herbals', as frequently reported in published studies, may not yield valid data resulting in a gross underestimation of actual use.

    Living in cold housing conditions and risk of fuel poverty presents a range of physiological and psychosocial health risks. Limited research has specifically investigated the effects of fuel poverty on children and young people, and even less has been conducted with youth input into the research process. The Cool? Study used mixed methods, participatory action research carried out with youth researchers involved at all stages through questionnaire design, analysis, qualitative design, e-interviewing and dissemination of results. This article reports on results of an online survey of 656 adolescents aged 14-16 years completed at 17 schools in New Zealand. Sampling was based on selecting schools for invitation, with the probability of selection weighted proportional to school size, within strata defined by climate zone. Results from a small e-mail interview study of survey respondents who consented to follow-up are also reported. The study found that almost half of the survey respondents (47%) felt their home was sometimes cold during the winter; a further 40% felt their home was often or always cold. More than two thirds of respondents (70%) had shivered inside at least once during winter. Respondents were more likely to report key indicators of fuel poverty depending on their self-reported ethnicity, with Māori at increased risk. Living in private rental housing or state-owned housing also increased risk of fuel poverty compared to those in owner-occupied dwellings. Participants of email interviews expressed concern about the widespread problem of cold housing for youth and a desire for Government intervention. The integrated results confirm that cold housing and risk of fuel poverty are important problems for young people in New Zealand. Results contribute to the evidence-base for policy targeting of schemes such as the Government-sponsored retrofitting of insulation to households with dependent children.

    There is limited research to date on the clinical music therapy internship experience from the perspective of the pre-professional. Further study is required to advance this significant stage in clinician development, as it is an intense period when pre-professionals apply and integrate theoretical knowledge about music therapy into their clinical practice. This study aimed to: (1) assess the skills, competence, comfort, concerns, issues, challenges, and anxieties of Canadian undergraduate students at two stages in the internship process (pre- and post-internship); and (2) examine whether these perceptions are consistent with published research on internship. Thirty-five pre-professionals, from a pool of 50 eligible respondents (70% response rate), completed a 57-question survey using a five-point Likert scale ranking pre- and post-internship experience and participated in an interview post-study. Survey results indicate a statistically significant increase in pre-professionals' perceived clinical, music, and personal skill development from pre- to post-internship. Areas of desired skill development included counseling, functional guitar, and clinical improvisation. Recommendations for educators and supervisors are provided with respect to areas of focus in undergraduate education and during clinical internship. © the American Music Therapy Association 2015.

    2018-02-01

    In 2016, the recommendations of the DICOM Standards Committee for the use of veterinary identification DICOM tags had its 10th anniversary. The goal of our study was to survey veterinary DICOM standard conformance in Germany regarding the specific identification tags veterinarians should use in veterinary diagnostic imaging. We hypothesized that most veterinarians in Germany do not follow the guidelines of the DICOM Standards Committee. We analyzed the metadata of 488 imaging studies of referral cases from 115 different veterinary institutions in Germany by computer-aided DICOM header readout. We found that 25 (5.1%) of the imaging studies fully complied with the "veterinary DICOM standard" in this survey. The results confirmed our hypothesis that the recommendations of the DICOM Standards Committee for the consistent and advantageous use of veterinary identification tags have found minimal acceptance amongst German veterinarians. DICOM does not only enable connectivity between machines, DICOM also improves communication between veterinarians by sharing correct and valuable metadata for better patient care. Therefore, we recommend that lecturers, universities, societies, authorities, vendors, and other stakeholders should increase their effort to improve the spread of the veterinary DICOM standard in the veterinary world.

    To describe methodology used to diagnose delirium in research studies evaluating delirium detection tools. The authors used a survey to address reference rater methodology for delirium diagnosis, including rater characteristics, sources of patient information, and diagnostic process, completed via web or telephone interview according to respondent preference. Participants were authors of 39 studies included in three recent systematic reviews of delirium detection instruments in hospitalized patients. Authors from 85% (N = 33) of the 39 eligible studies responded to the survey. The median number of raters per study was 2.5 (interquartile range: 2-3); 79% were physicians. The raters' median duration of clinical experience with delirium diagnosis was 7 years (interquartile range: 4-10), with 5% having no prior clinical experience. Inter-rater reliability was evaluated in 70% of studies. Cognitive tests and delirium detection tools were used in the delirium reference rating process in 61% (N = 21) and 45% (N = 15) of studies, respectively, with 33% (N = 11) using both and 27% (N = 9) using neither. When patients were too drowsy or declined to participate in delirium evaluation, 70% of studies (N = 23) used all available information for delirium diagnosis, whereas 15% excluded such patients. Significant variability exists in reference standard methods for delirium diagnosis in published research. Increasing standardization by documenting inter-rater reliability, using standardized cognitive and delirium detection tools, incorporating diagnostic expert consensus panels, and using all available information in patients declining or unable to participate with formal testing may help advance delirium research by increasing consistency of case detection and improving generalizability of research results.

    Priesack, Anneken; Alcock, John

    2015-05-01

    This paper reports findings from a survey which aimed to explore well-being and self-efficacy and test measures of those constructs with a sample of nurse students in a University setting in the United Kingdom. Evidence indicates that undergraduate nurse programmes combine academic work and clinical placement experience in a mix that can potentially lead to stress and impact on health and well-being. Self-efficacy is known to be a resource that contributes to well-being, resilience and academic achievement and therefore relevant for investigation. A cross-sectional survey approach was used to obtain data using a paper questionnaire including the BBC Well-being Scale and Generalised Self-efficacy Scale. A total of n=108 undergraduate preregistration nurse students participated in this small study from a potential population of 450. The majority of participants (86%) were female, and the majority (75%) were aged 17-35years old. Mean and subscale scores were calculated for both instruments and inferential analyses were carried out using non-parametric techniques. Exploratory factor analyses of the BBC Well-being Scale indicated a three factor structure consistent with validation study findings. Cronbach's alpha was α=.92 for the BBC Well-being Scale and α=.85 for the GSE suggesting that the instruments are valid and reliable measures for nurse education research. Nurse students indicated higher scores on the BBC Well-being Scale and the GSE compared with previously studied populations and a small but significant positive correlation was found between psychological well-being and self-efficacy. Cluster analysis indicated discrete student communities in this sample that varied in their Well-being and GSE scale and subscale scores. Self-efficacy and general well-being in nurse students are worthy of further study and relevant to contemporary nurse education given current interest in interventions to promote student retention and resilience post-registration.

    Quinlivan, Julie A; Miller, Mary; Hutton, Marani

    2017-12-01

    Objective Clinician engagement correlates with quality, safety and efficacy outcomes. The aim of the present study was to explore whether a clinical senate model achieves clinical input into system manager and operational health service boards. Methods A mixed-methods survey was undertaken. Participants were current or immediate past members of the Clinical Senate of Western Australia (CS). For the 124 surveys sent out, the response rate was 60%. Results Respondents stated the CS played a role in clinician engagement (95%), contributed to healthcare reform (82%), knowledge of contemporary health issues (92%), feedback to decision makers (82%), clinician networking (94%), debate on important issues (93%), enabled clinicians to work on recommendations to improve health at a state level (87%), contributed to clinician thinking on health reform (88%) and enabled clinicians to share their knowledge (91%). Four major themes emerged in the qualitative analysis: (1) the need for a strong independent clinician forum and voice at a state level; (2) the need to strengthen clinician interactions with operational healthcare boards; (3) a strong belief that clinician engagement strengthened quality and safety outcomes at a state level; and (4) that membership was important and needed to be diverse, multidisciplinary and independent, but structurally representative of clinicians in the state. Conclusion A clinical senate model can facilitate state-wide clinician engagement. What is known about the topic? High levels of clinical engagement foster a culture within healthcare organisations that is associated with the delivery of sustained high-quality, safe and efficient services. This has led to a focus on strategies to optimise clinical engagement in healthcare planning and reform. However, there is limited data exploring how to achieve clinical engagement at a state, rather than local, level within the healthcare system. What does this paper add? This survey study evaluates the

  20. Music Therapy Practice Status and Trends Worldwide: An International Survey Study.

    2017-11-01

    The field of music therapy is growing worldwide. While there is a wealth of country-specific information available, only a few have databased workforce censuses. Currently, little to no descriptive data exists about the global development of the profession. The purpose of this study was to obtain descriptive data about current demographics, practice status, and clinical trends to inform worldwide advocacy efforts, training needs, and the sustainable development of the field. Music therapists (N = 2,495) who were professional members of organizations affiliated with the World Federation of Music Therapy (WFMT) served as a sample for this international cross-sectional survey study. A 30-item online questionnaire was designed, pilot tested by key partners, and translated into seven languages. Researchers and key partners distributed the online survey through e-mail invitations and social media announcements. Professional music therapists worldwide are well-educated, mature professionals with adequate work experience, who are confident in providing high-quality services primarily in mental health, school, and geriatric settings. Due to ongoing challenges related to recognition and government regulation of the field as an evidence-based and well-funded healthcare profession, most individuals work part-time music therapy jobs and feel underpaid. Yet, many music therapists have a positive outlook on the field's future. Continued research and advocacy efforts, as well as collaborations with lobbyists, business consultants, and credentialing/licensure experts to develop progressive strategies, will be crucial for global development and sustainability of the field.
