    Full Text Available Abstract Background The subject of death and bereavement in the context of randomised controlled trials in neonatal or paediatric intensive care is under-researched. The objectives of this phase of the Bereavement and RAndomised ControlLEd Trials (BRACELET Study were to determine trial activity in UK neonatal and paediatric intensive care (2002-06; numbers of deaths before hospital discharge; and variation in mortality across intensive care units and trials and to determine whether bereavement support policies were available within trials. These are essential prerequisites to considering the implications of future policies and practice subsequent to bereavement following a child's enrolment in a trial. Methods The units survey involved neonatal units providing level 2 or 3 care, and paediatric units providing level II care or above; the trials survey involved trials where allocation was randomized and interventions were delivered to intensive care patients, or to parents but designed to affect patient outcomes. Results Information was available from 191/220 (87% neonatal units (149 level 2 or 3 care; and 28/32 (88% paediatric units. 90/177 (51% eligible responding units participated in one or more trial (76 neonatal, 14 paediatric and 54 neonatal units and 6 paediatric units witnessed at least one death. 50 trials were identified (36 neonatal, 14 paediatric. 3,137 babies were enrolled in neonatal trials, 210 children in paediatric trials.

    The goal of the study is to verify if Transylvanian gold was used to manufacture Romanian archaeological objects using information related to trace elements: Sb, Te, Pb - recognized fingerprints for Carpathian Mountains mines and Sn characteristic for the panned river-bed (alluvional) gold. To solve these issues, samples (grains, nuggets,fine gold s and ) from various Transylvanian mines and rivers and some very small (few milligrams) fragments of archaeological objects are measured. During the experiment, point spectra for 22 natural gold samples from Tran sylvania and 18 m icronic s amples from archaeological objects were acquired at 34 keV excitation SR energy, using a spatially resolved SR-XRF set-up mounted for analyses at the hard X-ray beam line - BAMline at BESSY, Berlin. A summary for the characterization of Transylvanian native gold is the following: high (8 - 30%) Ag amounts and low (0.2 - 1%) Cu amounts; placer deposits (Valea Oltului, Stanija, Valea Pianului) contain as fingerprint Sn (150-300 ppm) - most probably from river bed cassiterite; primary deposits present as fingerprints Te (200-2000 ppm), Sb (150-300 ppm) - however, the samples are very inhomogeneous; primary deposit Sacaramb contains Te 0,25%, Sb (500 ppm), but also Sn ( 200 ppm); primary deposit Fizesti presents a big amount of Pb 1%, Sb (350 ppm), traces of Te and also Sn. As concerning the k oson d acian coins, the type w ith monogram i s made from refined (more than 97%) gold with no Sb, Te or Sn traces (remelted gold) and the type w ithout monogram i s clearly made from alluvial gold, partially combined with primary Transylvanian gold (Sn and Sb traces detected). A spectacular application of the micro-SR-XRF studies on native gold was the one of authentication of some recovered heritage artifacts: five Dacian gold bracelets exhibited at the National Museum of Romania's History, Bucharest. The Dacian multi-spiraled bracelets were made of gold; they belong to the classical period of the

    The contents of 3d-transition metals (Ti, V, Cr, Mn, Fe, Co, Ni, Cu and Zn) in fragments of medieval glass bracelets, found in the necropolis of Stambolovo and the castle of Mezek, Bulgaria, were determined by total reflection X-ray fluorescence (TXRF) analysis using gallium as internal standard. The samples were analysed as slurries in Triton X 114. The experimental parameters: grain size of the glass sample, concentrations of glass sample, Triton X114 and internal standard in the slurry, volume of the slurry aliquot taken for analysis, as well as the excitation time, were optimised. For method validation the certified reference material BAM-S005 Type A soda-lime glass was used. It was proven that the elements Co, Mn and Fe are responsible for colour generation in the investigated glass samples. The precision of the determinations is characterised by an RSD in the range 3–11%

    Trace-elements are more significant for provenancing archaeological metallic artifacts than the main components. For gold, the most promising elements are platinum group elements (PGE), Sn, Te, Sb, Hg and Pb. Several small fragments of natural Transylvanian gold - placer and primary - were studied by using micro-PIXE technique at the Legnaro National Laboratory AN2000 microbeam facility, Italy and at the AGLAE accelerator, C2RMF, Paris, France and by using micro synchrotron radiation X-ray fluorescence (micro-SR-XRF) at BESSY synchrotron, Berlin, Germany. The goal of the study was to identify the trace-elements, especially Sn, Sb and Te. A spectacular application to five Dacian gold bracelets authentication is presented (Sn and Sb traces)

    Full Text Available Athletes are constantly searching for something that will give them a competitive edge. Performance jewelry is one of the latest products on the market designed to improve athletic performance. The most common claims are that wearing this performance jewelry will improve flexibility, balance, and strength. There is considerable marketing of these products, including testimonial evidence by high profile athletes, in support of the purported benefits. In demonstrations designed to validate the performance enhancing benefits of these products, however, companies typically conduct the testing in the following sequence: The first trial is done without the bracelet on and the second trial is performed with the bracelet on. Invariably, subjects perform better on the second trial. This brings into questions whether the improvement on the second trial is due to 1 a benefit of the bracelet, 2 the fact the subjects were warmed-up (Maud et al., 2006a; 2006b, 3 subjects being habituated to the task (Benson and Friedman, 1996; Wright et al., 2009, or 4 a placebo effect (Beedie and Foad, 2009.One of the most popular performance enhancing bracelets currently on the market is sold by Power Balance® (www.powerbalance.com. The Power Balance® bracelet has two dime-sized holograms; one on either side of the bracelet. The holograms within the Power Balance® bracelet are designed to "resonate with and respond to the natural energy field of the body". This purportedly improves flexibility, balance, and strength. To our knowledge, no randomized, double- blind, placebo trials have ever been conducted evaluating the validity of these claims. Thus, the purpose of this study was to evaluate whether wearing of the Power Balance® bracelet can improve trunk flexibility, balance, strength, and lower body power.Forty-two NCAA Division III athletes (22M: 20.1 ± 1.4 years, 1.82 ± 6.4 m, 82.0 ± 12.6 kg; 20F: 19.5 ± 1.3 years, 1.66 ± 6. 8 m, 63.2 ± 8.1 kg completed four

    Full Text Available Background: Recently, emotion recognition has become a hot topic in human-computer interaction. If computers could understand human emotions, they could interact better with their users. This paper proposes a novel method to recognize human emotions (neutral, happy, and angry using a smart bracelet with built-in accelerometer. Methods: In this study, a total of 123 participants were instructed to wear a customized smart bracelet with built-in accelerometer that can track and record their movements. Firstly, participants walked two minutes as normal, which served as walking behaviors in a neutral emotion condition. Participants then watched emotional film clips to elicit emotions (happy and angry. The time interval between watching two clips was more than four hours. After watching film clips, they walked for one minute, which served as walking behaviors in a happy or angry emotion condition. We collected raw data from the bracelet and extracted a few features from raw data. Based on these features, we built classification models for classifying three types of emotions (neutral, happy, and angry. Results and Discussion: For two-category classification, the classification accuracy can reach 91.3% (neutral vs. angry, 88.5% (neutral vs. happy, and 88.5% (happy vs. angry, respectively; while, for the differentiation among three types of emotions (neutral, happy, and angry, the accuracy can reach 81.2%. Conclusions: Using wearable devices, we found it is possible to recognize human emotions (neutral, happy, and angry with fair accuracy. Results of this study may be useful to improve the performance of human-computer interaction.

    To measure the bracelet automatically, a novel method based on feature energy is proposed. Firstly, the morphological method is utilized to preprocess the image, and the contour consisting of a concentric circle is extracted. Then, a feature energy function, which is relevant to the distances from one pixel to the edge points, is defined taking into account the geometric properties of the concentric circle. The input image is subsequently transformed to the feature energy distribution map (FEDM) by computing the feature energy of each pixel. The center of the concentric circle is thus located by detecting the maximum on the FEDM; meanwhile, the radii of the concentric circle are determined according to the feature energy function of the center pixel. Finally, with the use of a calibration template, the internal diameter and thickness of the bracelet are measured. The experimental results show that the proposed method can measure the true sizes of the bracelet accurately with the simplicity, directness and robustness compared to the existing methods.

    2005-01-01

    Full Text Available The jewelry worn in the Roman times by the women of Palmyra is best known to us from the tombstones. The archaeological confirmation for the use of these adornments represented on Palmyrene reliefs is a pair of golden bracelets discovered in Viminacium. Very close analogy for this jewelry is a pair of silver bracelets from a treasure discovered at the site Rhetel in Gaul. One less luxurious specimen made of bronze and discovered in the course of systematic investigations of Sirmium in 1976 also belongs to this distinct group of Roman bracelets. Jewelry from Sirmium, Viminacium and Gaul, shows that decorative system, originating from Palmyrene bracelets, quickly entered, in the middle and during the second half of the 3rd century, the repertoire of some goldsmiths' workshops in the West, where experienced various transformations.

    Fragments of two perfume bottles belonging to the Hellenistic and Roman periods, and five bracelets belonging to the Roman, Byzantine, and Ottoman periods, excavated in the archaeological site of Enez during the excavations in 2000, have been investigated. The samples were analyzed using micro-Raman, FTIR, and energy dispersive X-ray fluorescence techniques, in order to study the ancient technology of glass production and to determine chemical compositions of the basic components and coloring elements of the glassware. All the investigated glasses can be characterized as low-magnesia-soda-lime silicate glasses, whose colors are induced by metal ions. The melting points of the investigated glasses are estimated to be quite close to each other and around 1000°C.

    A wide variety of cyclic molecular architectures are built of modular subunits and can be formed combinatorially. The mathematics for enumeration of such objects is well-developed yet lacks key features of importance in chemistry, such as specifying (i) the structures of individual members among a set of isomers, (ii) the distribution (i.e., relative amounts) of products, and (iii) the effect of nonequal ratios of reacting monomers on the product distribution. Here, a software program (Cyclaplex) has been developed to determine the number, identity (including isomers), and relative amounts of linear and cyclic architectures from a given number and ratio of reacting monomers. The program includes both mathematical formulas and generative algorithms for enumeration; the latter go beyond the former to provide desired molecular-relevant information and data-mining features. The program is equipped to enumerate four types of architectures: (i) linear architectures with directionality (macroscopic equivalent = electrical extension cords), (ii) linear architectures without directionality (batons), (iii) cyclic architectures with directionality (necklaces), and (iv) cyclic architectures without directionality (bracelets). The program can be applied to cyclic peptides, cycloveratrylenes, cyclens, calixarenes, cyclodextrins, crown ethers, cucurbiturils, annulenes, expanded meso-substituted porphyrin(ogen)s, and diverse supramolecular (e.g., protein) assemblies. The size of accessible architectures encompasses up to 12 modular subunits derived from 12 reacting monomers or larger architectures (e.g. 13-17 subunits) from fewer types of monomers (e.g. 2-4). A particular application concerns understanding the possible heterogeneity of (natural or biohybrid) photosynthetic light-harvesting oligomers (cyclic, linear) formed from distinct peptide subunits.

  4. Studying dark energy with galaxy cluster surveys

    Galaxy cluster surveys provide a powerful means of studying the density and nature of the dark energy. The redshift distribution of detected clusters in a deep, large solid angle SZE or X-ray survey is highly sensitive to the dark energy equation of state. Accurate constraints at the 5% level on the dark energy equation of state require that systematic biases in the mass estimators must be controlled at better than the ∼10% level. Observed regularity in the cluster population and the availability of multiple, independent mass estimators suggests these precise measurements are possible. Using hydrodynamical simulations that include preheating, we show that the level of preheating required to explain local galaxy cluster structure has a dramatic effect on X-ray cluster surveys, but only a mild effect on SZE surveys. This suggests that SZE surveys may be optimal for cosmology while X-ray surveys are well suited for studies of the thermal history of the intracluster medium

    Patients can play an important role in reducing healthcare harm but little is known about the factors that may affect patients' willingness to participate. In order to encourage the 'active' patient it is critical that we gain a deeper understanding of the antecedents of safety-relevant behaviours. Doing this will enable the implementation of effective interventions aimed at supporting patients to work with healthcare professionals in ensuring safe care. To examine predictors of patients' intentions to engage in two safety behaviours: (1) reminding healthcare staff to wash their hands and; (2) notifying healthcare staff if they are not wearing a hospital identification bracelet. Cross-sectional survey study. A purposive sampling method was employed to recruit 80 medical and surgical hospital inpatients aged 18-80 (mean 48) from one inner city London teaching hospital. A 42 item survey that measured the extent that patients' control beliefs, behavioural beliefs, normative beliefs and perceived susceptibility and severity towards a hospital-acquired infection or a misidentification error could predict their intentions to ask doctors/nurses about their hand washing compliance or notify doctors/nurses if they are not wearing a hospital identification bracelet. Data was analysed using multiple regression analysis. Control beliefs, normative beliefs and perceived severity were the strongest predictors of patients' intentions to participate in both behaviours. The regression models accounted for a smaller percentage of the variance in patients' intentions to ask doctors/nurses if they have washed their hands (42%/37%) than notifying staff if they were not wearing an identification bracelet (54%/56%). If patients understand why a behaviour is beneficial, they perceive it as acceptable to participate in and that they have control over the decision to engage in the behaviour, we hypothesise that more patients will intend to participate in that behaviour.

    2011-09-14

    Stable bracelet-like magnetic nanorings, formed by Ag-Fe(3)O(4) nanoparticles with an average size around 40 nm, have been successfully prepared in large scale by means of reducing Ag(+) and Fe(3+) simultaneously under mild conditions. In the reaction, tiny grains of silver are used as seeds to prompt small Fe(3)O(4) nanoparticles to grow larger, which is essential to enhance the magnetic dipole-dipole interactions, while only superparamagnetic Fe(3)O(4) nanoparticles (about 10 nm in size) can be obtained in the absence of Ag seeds. The XRD, TEM, SAED and the EDS line scan data reveal that these nanoparticles are in the core-shell structure. These magnetic Ag-Fe(3)O(4) nanoparticles assembled into nanorings by magnetic dipole-dipole interactions with a diameter of 100-200 nm. The saturation magnetization of the nanorings is 39.5 emu g(-1) at room temperature. The MRI images indicate that these kind of nanorings have the potential application in diagnostics as a T(2) MRI contrast agent. This journal is © The Royal Society of Chemistry 2011

    Distal fingertip amputations are common injuries in work- and non-work-related accidents. There is a paucity of evidence to support use of any one treatment. We conducted a study to better understand how surgeon and patient factors influence the treatment preferences for distal fingertip amputations among a cross section of US and international hand surgeons. We sent a 16-question survey to the American Association for Hand Surgery and reciprocal international hand societies and analyzed the response data using a logistic regression model. We hypothesized that hand surgeons' treatment preferences would be varied and influenced by surgeon and patient demographics. One hundred ninety-eight hand surgeons (62% US, 38% international) responded to the survey. For each clinical scenario (Allen levels 2, 3, and 4 and volar oblique amputations), there were wide variations in treatment preferences. Wound care was less likely performed by surgeons with more than 30 years of experience or plastic surgery backgrounds. Replantation was less likely performed by US surgeons and private practice surgeons. Pedicle and homodigital flaps were more commonly performed internationally. Surgeons in practice for less than 5 years were more likely to perform skeletal shortening. For all levels and orientations of fingertip amputation queried, there is a wide range of treatment preferences. Our survey results highlight the need for a prospective randomized trial to elucidate the most effective treatments for fingertip amputations.

    In the current automobile market buffeting is one of the customer frequent complaints on luxury cars and SUVs. Buffeting is a low frequency but high level wind noise and makes people inside the vehicle uncomfortable if it lasts for a long period of time. The physical mechanism of buffeting is a complicated phenomenon of aeroacoustic resonance. The aeroacoustic characteristics of buffeting depend on vehicle features and operating conditions. In this paper, a survey of CFD studies on the automotive buffeting is presented. Firstly, several buffeting related concepts, such as Helmholtz resonator, flow over a cavity, shear layer instability and vortex shedding, are reviewed and relevant references are listed. Then, a historic survey of the buffeting investigation is made with emphasis on computational studies. As an example, the buffeting studies at DaimlerChrysler are selected to demonstrate the procedure of CFD simulation for automotive buffeting. The procedure is then validated by the correlation with wind tunnel testing. After that the validated procedure is applied to find solutions for buffeting reduction. Finally, some comments on buffeting studies are addressed. (author)

    NRPB's national survey of natural radiation exposure in homes commenced in 1982 and will run until 1984. A pilot survey was undertaken in over 100 homes for one year, using passive thermoluminescent dosemeters to measure external radiation from terrestrial and cosmic sources and passive radon dosemeters to measure the radon-222 gas concentration. A preliminary analysis of the results obtained from the pilot survey is given. The main value of the pilot survey was in providing experience and various administrative and scientific procedures have been simplified or automated for the national survey. (U.K.)

    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.

    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.

  18. LITERATURE SURVEY FOR FRACTIONAL CRYSTALLIZATION STUDY

    PERSON, J.C.

    2004-01-01

    The literature survey for the fractional crystallization study of material from tank 241-S-112 is completed, fulfilling the requirements of the Test Plan for Tank 241-S-112 Fractional Crystallization Study (Herting 2003). Crystallization involves the formation of one or more solid phases from a fluid phase or an amorphous solid phase. It is applied extensively in the chemical industry, both as a purification process and a separation process. The main advantage of crystallization over distillation is the production of substances with a very high purity, at a low level of energy consumption, and at relatively mild process conditions. Crystallization is one of the older operations in the chemical industry; therefore, practical experience can usually be used for the design and operation of industrial crystallizers. In addition, advances in the understanding of crystallization kinetics can be useful in the control, design, and scale-up of industrial crystallizers. Research work is currently underway; e.g., the CrysCODE (Crystallizer Control and Design) project, littu://www.aui.tudelft.nl/uroiect/Cn/scode/crvscode.htm, at the Delft University of Technology, with the goal of improving the performance and controllability of industrial crystallizers by means of better control and improved design methodologies. Recent developments in fluid dynamics and reactor technology (e.g., compartment approaches) have led to a better understanding of processes and scale-up phenomena. The ultimate aim of such research is to develop a knowledge-based design frame for optimization of industrial crystallization units. Development work is in progress on a rigorous design analysis model for the description of the crystallization process as a function of the reactor geometry, crystallization kinetics, and operating conditions. One modeling effort is aimed at improving the predictive crystallizer model by implementing a population balance equation that depends on two variables: the size and

    The airborne magnetic survey is a cost-effective method for regional geological investigation. Most of developed countries use aeromagnetic data as important fundamental information for resources development. The first aeromagnetic survey was conducted in the offshore areas of west and southern Taiwan in 1968 by U.S. Naval Oceanographic Office to help Taiwan finding oil. Later, in 2007, a helicopter-borne magnetic survey was proceed in east Taiwan for underground granite bodies. In order to improve better understanding of deep geological structures associated with the Holocene volcanism in Taiwan, we applied helicopter-borne magnetic technique in northern Taiwan include Tatun Volcano Group (TVG) and Kueishan island in 2013 and 2014 to obtain the distribution information of potential magma chamber as well as hydrothermal pathways along regional geological structures. The most important findings of the high-resolution aeromagnetic dataset since 1960's to 2014 acquired include: (1) the distribution of subsurface igneous rocks and the Curie point depth in Tatun Volcano Group, Keelung Volcano Group, and Kueishantao Volcano; (2) the widely distributed NE high-magnetic belts in northern Taiwan may be associated with NE fractures created by long-term subsidence in this area; (3) the high-magnetic belts in south of Lanyang River which is very different from the magnetic characteristics of the Central Range may imply paleo oceanic plate; (4) the NE high-magnetic belts in Penghu area formed by magma intrusion along NE fractures and the dense and high-magnetic anomalies may be associated with the Miocene basaltic lava overlying on the pre-Tertiary igneous dykes and are widely spread in northern Penghu area. The new aeromagnetic survey techniques help us to investigate the areas with steep terrain or covered by dense vegetation which was difficult to obtain reasonable geological understanding, and also provide an opportunity for us to apply the geothermal energy prospecting.

    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 accommodation (r convergence near point (r = 0.26, p < 0.05) were not significant. Our results confirmed that using different subjective symptom surveys can provide different results within the same subject group, therefore we recommend to use surveys as a part of case 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.

    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

    Full Text Available Abstract Background Musculoskeletal impairment (MSI is an important cause of morbidity and mortality worldwide, especially in developing countries. Prevalence studies for MSI in the developing world have used varying methodologies and are seldom directly comparable. This study aimed to develop a new tool to screen for and diagnose MSI and to pilot test the methodology for a national survey in Rwanda. Methods A 7 question screening tool to identify cases of MSI was developed through literature review and discussions with healthcare professionals. To validate the tool, trained rehabilitation technicians screened 93 previously identified gold standard 'cases' and 86 'non cases'. Sensitivity, specificity and positive predictive value were calculated. A standardised examination protocol was developed to determine the aetiology and diagnosis of MSI for those who fail the screening test. For the national survey in Rwanda, multistage cluster random sampling, with probability proportional to size procedures will be used for selection of a cross-sectional, nationally representative sample of the population. Households to be surveyed will be chosen through compact segment sampling and all individuals within chosen households will be screened. A pilot survey of 680 individuals was conducted using the protocol. Results: The screening tool demonstrated 99% sensitivity and 97% specificity for MSI, and a positive predictive value of 98%. During the pilot study 468 out of 680 eligible subjects (69% were screened. 45 diagnoses were identified in 38 persons who were cases of MSI. The subjects were grouped into categories based on diagnostic subgroups of congenital (1, traumatic (17, infective (2 neurological (6 and other acquired(19. They were also separated into mild (42.1%, moderate (42.1% and severe (15.8% cases, using an operational definition derived from the World Health Organisation's International Classification of Functioning, Disability and Health

    2015-09-01

    Full Text Available Many official statistics across the UK Government Statistical Service (GSS are produced using data collected from sample surveys. These survey data are used to estimate population statistics through weighting and calibration techniques. For surveys with complex or unusual sample designs, the weighting can be fairly complicated. Even in more simple cases, appropriate software is required to implement survey weighting and estimation. As with other stages of the survey process, it is preferable to use a standard, generic calibration tool wherever possible. Standard tools allow for efficient use of resources and assist with the harmonisation of methods. In the case of calibration, the Office for National Statistics (ONS has experience of using the Statistics Canada Generalized Estimation System (GES across a range of business and social surveys. GES is a SAS-based system and so is only available in conjunction with an appropriate SAS licence. Given recent initiatives and encouragement to investigate open source solutions across government, it is appropriate to determine whether there are any open source calibration tools available that can provide the same service as GES. This study compares the use of GES with the calibration tool ‘R evolved Generalized software for sampling estimates and errors in surveys’ (ReGenesees available in R, an open source statistical programming language which is beginning to be used in many statistical offices. ReGenesees is a free R package which has been developed by the Italian statistics office (Istat and includes functionality to calibrate survey estimates using similar techniques to GES. This report describes analysis of the performance of ReGenesees in comparison to GES to calibrate a representative selection of ONS surveys. Section 1.1 provides a brief introduction to the current use of SAS and R in ONS. Section 2 describes GES and ReGenesees in more detail. Sections 3.1 and 3.2 consider methods for

  9. Pain and Joy of a Panel Survey on Transport Studies

    Comendador Arquero, María Eugenia López-Lambas

    2016-07-01

    Over ten years ago, it was established that the most frequent reason that motivates a panel survey on transport studies is the evaluation of a change in the transportation system, or a specific transportation-planning project, especially when the project involves novel elements. From a statistical viewpoint, a panel survey has the definite advantage to offer more accurate estimatesof changes than cross-sectional surveys for the same sample size. Observing travel patterns of individuals and households overseveral consecutive days, has offered insights into activity scheduling and travel planning. Variability in travel patterns has important policy implications as well, but how much effort is worth to design a panel survey? To evaluate the effects of the transport policies introduced in Madrid during the last five years, a ‘short-long’ panel survey wasbuilt, based on a sample of a Madrid-worker subpopulation most affected by those recent changes in transport policy. The paper describes both the design and construction of the panel based on GPS technology, and presents some results based on an analysis of its two waves; for example, it registered an increment of public transport use and walking trips in 10%. The panel overcomes the known attrition problem thanks to providing incentives, maintaining contact, using the same interviewer for the same respondents, and conducting face-to-face interviews.

    In previous study, we demonstrated a new method to prepare polymeric fiber adsorbents via a chemical-grafting method, namely atom-transfer radical polymerization (ATRP), and identified parameters affecting their uranium adsorption capacity. However, ATRP chemical grafting in the previous study still utilized conventional radiation-induced graft polymerization (RIGP) to introduce initiation sites on fibers. Therefore, the objective of the present study is to perform survey study of trunk fiber materials for direct ATRP chemical grafting method without RIGP for the preparation of fiber adsorbents for uranium recovery from seawater.

Earlier studies show the importance of motivation for study commitment and result. The aim was to analyze nursing students' estimation of their degree of motivation during different semester during their education and to identify reasons for the degree of motivation. Methods A questionnaire asking for scoring motivation and what influenced the degree of motivation was distributed to students enrolled in a nursing programme. 315 students who studied at different semesters participated. Analyzes were made by statistical calculation and content analysis. Results The mean motivation score over all semesters was 6.3 (ranked between 0–10 and differed significantly during the semesters with a tendency to lower score during the 5th semester. Students (73/315 with motivation score 6 reported positive opinions to becoming a nurse (125/234, organization of the programme and attitude to the studies. The mean score value for the motivation ranking differed significantly between male (5.8 and female (6.8 students. Conclusion Conclusions to be drawn are that nursing students mainly grade their motivation positive distributed different throughout their entire education. The main motivation factor was becoming a nurse. This study result highlights the need of understanding the students' situation and their need of tutorial support.

    Introduction Access to quality healthcare services is considered a moral right. However, for people living in regional locations, timely access to the services that they need may not always be possible because of structural and attitudinal barriers. This suggests that people living in regional areas may have unmet healthcare needs. The aim of this research will be to examine the healthcare needs, expectations and experiences of regional South Australians. Methods and analysis The Regional South Australia Health (RESONATE) survey is a cross-sectional study of adult health consumers living in any private or non-private dwelling, in any regional, rural, remote or very remote area of South Australia and with an understanding of written English. Data will be collected using a 45-item, multidimensional, self-administered instrument, designed to measure healthcare need, barriers to healthcare access and health service utilisation, attitudes, experiences and satisfaction. The instrument has demonstrated acceptable psychometric properties, including good content validity and internal reliability, good test–retest reliability and a high level of acceptability. The survey will be administered online and in hard-copy, with at least 1832 survey participants to be recruited over a 12-month period, using a comprehensive, multimodal recruitment campaign. Ethics and dissemination The study has been reviewed and approved by the Human Research Ethics Committee of the University of South Australia. The results will be actively disseminated through peer-reviewed journals, conference presentations, social media, broadcast media, print media, the internet and various community/stakeholder engagement activities.

    To reassess cochleostomy techniques among North American cochlear implant surgeons after a 6-year period of widespread education and research on the topic. Prospective cohort study. A multiple-choice survey of cochlear implant techniques was distributed to surgeons attending the William House Cochlear Implant Study Group in 2006 and 2012. This survey contained questions regarding routine surgical access and cochleostomy techniques. Responses were anonymous, and >50% were repeat respondents. Statistical analysis sought changes in technique in the past 6 years. Comparisons between 2006 and 2012 responses revealed no significant changes in the proportion of surgeons identifying the facial nerve or chorda tympani. By contrast, respondents in 2012 were more likely to drill off the round window niche overhang (P < .001), use a round window insertion (P < .001), or make a smaller cochleostomy (P = .003). In two images of a transfacial recess approach, there was a significant increase in the proportion choosing an inferior or anterior cochleostomy site over a superior location (image 1, 76% in 2006 to 92% in 2012, P = .003; image 3, 78% to 90%, respectively, P = .044). This repeat survey documents a change in practice among cochlear implant surgeons. Specifically, scala tympani access techniques now appear to be more consistent with known anatomical relationships in the round window region. These findings may have resulted from the concerted education and research efforts over the past 6 years. © 2014 The American Laryngological, Rhinological and Otological Society, Inc.

    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.

    This report proposes a synthesis of a study based on a survey on energy consumption and expenditures directly paid by local communities, the built patrimony, public lighting and vehicle fuel, the electricity consumptions and expenditures of drinking water stations, sewage treatment plants and waste treatment plants. The survey has been performed among more than 1600 towns and communities of more than 500 inhabitants in metropolitan France and overseas territories. The considered built patrimony comprises schools, swimming pools, other sport facilities, administrative buildings, social and cultural facilities, and other various facilities. The report indicates key figures for 2012 in terms of global assessment, main consumer sectors, buildings, public lighting, vehicle fuel, actions for energy management, and renewable energies. The evolution of consumptions and expenditures is then analysed (evolution of main indicators, market shares of energies in buildings)

    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.

  19. 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

    Full Text Available Recent research has suggested a possible link between Parkinson's disease (PD and Fabry disease. To test this relationship, we administered a self-report and family history questionnaire to determine the prevalence of PD in Fabry disease patients and family members with likely pathogenic alpha-galactosidase A (GLA mutations. A total of 90 Fabry patients (77 from the online survey and 13 from the Icahn School of Medicine at Mount Sinai (ISMMS were included in the analysis. 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.

  1. Networking Journalism Studies: Towards a World Journalism Survey

    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.

  2. Econometric studies of urban population density: a survey.

    Mcdonald, J F

    1989-01-01

    This paper presents the 1st reasonably comprehensive survey of empirical research of urban population densities since the publication of the book by Edmonston in 1975. The survey summarizes contributions to empirical knowledge that have been made since 1975 and points toward possible areas for additional research. The paper also provides a brief interpretative intellectual history of the topic. It begins with a personal overview of research in the field. The next section discusses econometric issues that arise in the estimation of population density functions in which density is a function only of a distance to the central business district of the urban area. Section 4 summarizes the studies of a single urban area that went beyond the estimation of simple distance-density functions, and Section 5 discusses studies that sought to explain the variations across urban areas in population density patterns. McDonald refers to the standard theory of urban population density throughout the paper. This basic model is presented in the textbook by Mills and Hamilton and it is assumed that the reader is familiar with the model.

    The VST Optical Imaging of the CDFS and ES1 Fields (VOICE) Survey is a Guaranteed Time program carried out with the ESO/VST telescope to provide deep optical imaging over two 4 deg2 patches of the sky centred on the CDFS and ES1 pointings. We present the cosmic shear measurement over the 4 deg2 covering the CDFS region in the r-band using LensFit. Each of the four tiles of 1 deg2 has more than one hundred exposures, of which more than 50 exposures passed a series of image quality selection criteria for weak lensing study. The 5σ limiting magnitude in r- band is 26.1 for point sources, which is ≳1 mag deeper than other weak lensing survey in the literature (e.g. the Kilo Degree Survey, KiDS, at VST). The photometric redshifts are estimated using the VOICE u, g, r, i together with near-infrared VIDEO data Y, J, H, Ks. The mean redshift of the shear catalogue is 0.87, considering the shear weight. The effective galaxy number density is 16.35 gal/arcmin2, which is nearly twice the one of KiDS. The performance of LensFit on such a deep dataset was calibrated using VOICE-like mock image simulations. Furthermore, we have analyzed the reliability of the shear catalogue by calculating the star-galaxy cross-correlations, the tomographic shear correlations of two redshift bins and the contaminations of the blended galaxies. As a further sanity check, we have constrained cosmological parameters by exploring the parameter space with Population Monte Carlo sampling. For a flat ΛCDM model we have obtained Σ _8 = σ _8(Ω _m/0.3)^{0.5} = 0.68^{+0.11}_{-0.15}.

    In spring 1976 the Federal Ministry of Research and Technology has ordered a safety study to assess the risk for a nuclear power plant with a PWR. Giving first a survey on the main subtasks of the study the present state of work and some first results are discussed. Assuming a failure of safety systems a core melt event and a subsequent failure of the containment could occur. Corresponding accident sequences are discussed in some detail. Related hereto the results of some calculations for fission product release with respect to different containment failure modes are given. According to the results obtained so far the consequences of a core melt event can essentially be restricted by the retention function of the containment. (orig.) [de

    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

    A mail survey was conducted on 13,000 males in the JNIH-ABCC Life Span Study population aged 40 to 69 in January 1965. The information sought was largely related to what are considered to be risk factors in the development of cerebral and cardiovascular diseases. The questionnaire included such items as residential history, occupation, physical activity, smoking, dietary custom, educational history, medical history, and family history. The final response rate was high (93%) after three mailings and supplemental field visits. As a preliminary analysis, the distribution of these variables was compared by city and exposure status. This analysis revealed that Hiroshima subjects were more educated, were more often managers, clerical workers, and sales workers, performed less physical activity, had more living space and ate a more Western type diet than Nagasaki subjects. It was also shown that the distribution of such variables as place of birth, present address, occupation, marital status, and education differed by the exposure status of subjects. Some methodological problems inherent in a mail survey such as completeness and reliability of obtained information were discussed. 15 references, 1 figure, 28 tables.

    As a part of health survey in relation to air pollution, 16 smokers(11 from 'high' and 5 from 'low' zone) were studied with extensive serial lung functions, chest radiography and radioaerosol lung scanning. The clinical diagnosis were chronic bronchitis(COPD) in 9 subjects; but others (4 'High' and 3 'Low') were considered normal. The values of FVC, FEV were normal in most of these three groups, but FEV 1 /FVC percent values were lower in subjects from 'high' zone.The functional declines were higher in normals of 'high' zone. Radioaerosol (ventilation) scans (with technetium 99 ) showed a normal picture in 2 COPD and 3 normal subjects; in 3 COPD and 1 normal subjects the abnormalities were definite. For perfusion scans, 2 COPD and 3 normal subjects showed a normal pattern while definite abnormalities were seen in 1 COPD and 1 normal subjects. Lung scans may pick up abnormalities in normal smokers at an early stage. (author)

    Indirect calorimetry (IC) is the gold standard for determining energy expenditure in patients requiring mechanical ventilation. Metabolic armbands using data derived from dermal measurements have been proposed as an alternative to IC in healthy subjects, but their utility during critical illness is unclear. The aim of this study was to determine the level of agreement between the SenseWear armband and the Deltatrac Metabolic Monitor in mechanically ventilated intensive care unit (ICU) patients. Adult ICU patients requiring invasive ventilator therapy were eligible for inclusion. Simultaneous measurements were performed with the SenseWear Armband and Deltatrac under stable conditions. Resting energy expenditure (REE) values were registered for both instruments and compared with Bland-Altman plots. Forty-two measurements were performed in 30 patients. The SenseWear Armband measured significantly higher REE values as compared with IC (mean bias, 85 kcal/24 h; P = .027). Less variability was noted between individual SenseWear measurements and REE as predicted by the Harris-Benedict equation (2 SD, ±327 kcal/24 h) than when IC was compared with SenseWear and Harris-Benedict (2 SD, ±473 and ±543 kcal/24 h, respectively). The systematic bias and large variability of the SenseWear armband when compared with gas exchange measurements confer limited benefits over the Harris Benedict equation in determining caloric requirements of ICU patients.

    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.

    This report presents physical property logs of core samples from an offshore area near Eureka, CA. The cores were obtained as part of the STRATAFORM Program (Nittrouer and Kravitz, 1995, 1996), a study investigating how present sedimentation and sediment transport processes influence long-term stratigraphic sequences preserved in the geologic record. The core samples were collected during four separate research cruises to the northern California study area, and data shown in the logs of the cores were collected using a multi-sensor whole core logger. The physical properties collected are useful in identifying stratigraphic units, ground-truthing acoustic imagery and sub-bottom profiles, and in understanding mass movement processes. STRATA FORmation on Margins was initiated in 1994 by the Office of Naval Research, Marine Geology and Geophysics Department as a coordinated multi-investigator study of continental-margin sediment transport processes and stratigraphy (Nittrouer and Kravitz, 1996). The program is investigating the stratigraphic signature of the shelf and slope parts of the continental margins, and is designed to provide a better understanding of the sedimentary record and a better prediction of strata. Specifically, the goals of the STRATAFORM Program are to (Nittrouer and Kravitz, 1995): - determine the geological relevance of short-term physical processes that erode, transport, and deposit particles and those processes that subsequently rework the seabed over time scales - improve capabilities for identifying the processes that form the strata observed within the upper ~100 m of the seabed commonly representing 104-106 years of sedimentation. - synthesize this knowledge and bridge the gap between time scales of sedimentary processes and those of sequence stratigraphy. The STRATAFORM Program is divided into studies of the continental shelf and the continental slope; the geotechnical group within the U.S. Geological Survey provides support to both parts

    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.

  16. Management of postoperative pseudomeningoceles: an international survey study.

    2014-11-01

    Pseudomeningoceles are common complications after posterior fossa and intradural spinal surgery and are often asymptomatic. Management guidelines are lacking, and anecdotally, we have encountered radically different suggested treatments varying from observation to immediate surgical intervention. The goal of this study was to determine the prevailing opinions among neurosurgeons on the management of this condition. Neurosurgeons from around the world were invited via an International Society for Pediatric Neurosurgery (ISPN) and Neurosurgery ListServ e-blast to participate in a 33-question survey on the management of pseudomeningoceles, presented as simulated scenarios after posterior fossa and spinal intradural surgery. Two hundred forty-one responses were obtained. Pseudomeningoceles after posterior fossa tumor resection, in the absence of hydrocephalus, were typically managed nonoperatively for 7 to 14 days before re-exploration. Only 0.5 % of the surgeons would offer upfront repair of the pseudomeningocele. In the presence of hydrocephalus, 48 % of the neurosurgeons intervene initially with cerebrospinal fluid (CSF) diversion and would change therapy if the lesion did not resolve in 2 to 4 days. Ninety percent of the surgeons manage spinal pseudomeningoceles nonoperatively for 7-14 days before re-exploration is considered. The most common steps taken to prevent pseudomeningoceles are watertight closure, tissue glues, and duroplasty. The present zeitgeist suggests that, in the absence of hydrocephalus, initial observation is appropriate for cranial and spinal pseudomeningoceles. Operative revision should be reserved for failure of conservative treatment. If hydrocephalus is present, consideration should be made for CSF diversion. This study may serve as a guideline regarding acceptable management.

    2014-02-01

    Full Text Available An extrajudicial accounting survey can be required by the party or parties who set the objectives the chartered accountant should meet, representing an efficient highly specialized assistance tool for any business which wants to be protected from risks. The extrajudicial accounting survey has a much larger and more complex span than the judicial one, aiming at different issues: economic, patrimonial, managerial, financial, fiscal, information ones, surpassing most of the times the strict frame of financial and accounting information and services. The aim of the paper is to emphasize the deeply applicative character of the extrajuridical accounting survey in clarifying varying aspects that occur in a company‘s activity and that affect the decision making. The article focuses on the presentation of a sample extrajuridical accounting survey report with remarks, which, both in form and content, can become a source of inspiration both for theoretical debates and in the practical activity. In the international practice, the extrajudicial accounting surveys are used both for making important economic decisions, and for the fair information of all those who use accounting information, for certifying certain calculations or information, for rationalizing information flows etc.

    2017-10-01

    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.

    Evidence Based Medicine (EBM) is increasingly being applied to inform clinical decision-making in orthopaedic surgery. Despite the promotion of EBM in Orthopaedic Surgery, the adoption of results from high quality clinical research seems highly unpredictable and does not appear to be driven strictly by randomized trial data. The objective of this study was to pilot a survey to determine if we could identify surgeon opinions on the characteristics of research studies that are perceived as being most likely to influence clinical decision-making among orthopaedic surgeons in Canada. A 28-question electronic survey was distributed to active members of the Canadian Orthopaedic Association (COA) over a period of 11 weeks. The questionnaire sought to analyze the influence of both extrinsic and intrinsic characteristics of research studies and their potential to influence practice patterns. Extrinsic factors included the perceived journal quality and investigator profiles, economic impact, peer/patient/industry influence and individual surgeon residency/fellowship training experiences. Intrinsic factors included study design, sample size, and outcomes reported. Descriptive statistics are provided. Of the 109 members of the COA who opened the survey, 95 (87%) completed the survey in its entirety. The overall response rate was 11% (95/841). Surgeons achieved consensus on the influence of three key designs on their practices: 1) randomized controlled trials 94 (99%), 2) meta-analysis 83 (87%), and 3) systematic reviews 81 (85%). Sixty-seven percent of surgeons agreed that studies with sample sizes of 101-500 or more were more likely to influence clinical practice than smaller studies (n = design influencing adoption included 1) reputation of the investigators (99%) and 2) perceived quality of the journal (75%). Although study design and sample size (i.e. minimum of 100 patients) have some influence on clinical decision making, surgeon respondents are equally influenced

    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

    We developed a quantitative method for attaining a representative sample during sampling survey of RI waste. Considering a source, process, and type of RI waste, the method computes the number of sample, confidence interval, variance, and coefficient of variance. We also systematize the method of sampling survey logically and quantitatively. The result of this study can be applied to sampling survey of low- and intermediate-level waste generated from nuclear power plant during the transfer process to disposal facility.

    2018-01-01

    Summary Background Chromium (Cr) is a common skin sensitizer. The use of Cr(VI) in leather is restricted in the EU, but that of Cr(III) is not. Objectives To assess whether prolonged exposure to Cr‐tanned leather with mainly Cr(III) release may elicit allergic contact dermatitis in Cr‐allergic individuals. Method Ten Cr‐allergic subjects and 22 controls were patch tested with serial dilutions of Cr(III) and Cr(VI), and with leather samples. They then conducted a use test with a Cr‐tanned and a Cr‐free leather bracelet over a period of 3 weeks, for 12 h per day. Cr deposited on the skin from the bracelets was measured in the controls, and the diphenylcarbazide test for Cr(VI) and extraction tests for Cr(III) and Cr(VI) were conducted for the different leathers. Results Four of 10 Cr‐allergic subjects developed positive reactions to the Cr‐tanned bracelet within 7–21 days, whereas only 1 of 10 had a positive patch test reaction to this leather. Cr released from the Cr‐tanned leather was most probably entirely Cr(III), with a quantifiable amount being deposited on the skin. Conclusions This study strongly suggests that prolonged and repeated exposure to Cr‐tanned leather with mainly Cr(III) release is capable of eliciting allergic contact dermatitis in Cr‐allergic individuals.

    2018-02-01

    The aim of the study was to estimate the physical activity (PA) level among the professional college students in North India. One hundred three professional college students in the age group of 18-25 years were recruited by simple random sampling for this cross-sectional online survey. The survey was advertised on the social networking sites (Facebook, WhatsApp) through a link www.surveymonkey.com/r/MG-588BY. A Short Form of International Physical Activity Questionnaire was used for this survey study. The questionnaire included total 8 questions on the basis of previous 7 days. The questionnaire consists of 3 main categories which were vigorous, moderate and high PA. Time spent in each activity level was multiplied with the metabolic equivalent of task (MET), which has previously set to 8.0 for vigorous activity, 4.0 for moderate activity, 3.3 for walking, and 1.5 for sitting. By multiplying MET with number of days and minutes performed weekly, amount of each activity level was calculated and measured as MET-min/wk. Further by adding MET minutes for each activity level, total MET-min/wk was calculated. Total number of 100 students participated in this study, and it was shown that all professional course students show different levels in PA. The total PA level among professional college students, which includes, physiotherapy, dental, medical, nursing, lab technician, pharmacy, management, law, engineering, were 434.4 (0-7,866), 170.3 (0-1,129), 87.7 (0-445), 102.8 (0-180), 469 (0-1,164), 0 (0-0), 645 (0-1,836), 337 (0-1,890), 396 (0-968) MET-min/wk respectively. PA levels among professional college students in North India have been established.

  1. Alcohol responsiveness in laryngeal dystonia: A survey study

    Kirke, Diana N.; Frucht, Steven J.; Simonyan, Kristina

    2015-01-01

    Laryngeal dystonia (LD) is a task-specific focal dystonia of unknown pathophysiology affecting speech production. We examined the demographics of anecdotally reported alcohol use and its effects on LD symptoms using an online survey based on Research Electronic Data Capture (REDCap™) and National Spasmodic Dysphonia Association’s patient registry. From 641 participants, 531 were selected for data analysis, and 110 were excluded because of unconfirmed diagnosis. A total of 406 patients (76.5%) had LD and 125 (23.5%) had LD and voice tremor (LD/VT). The consumption of alcohol was reported by 374 LD (92.1%) and 109 LD/VT (87.2%) patients. Improvement of voice symptoms after alcohol ingestion was noted by 227 LD (55.9% of all patients) and 73 LD/VT (58.4%), which paralleled the improvement observed by patient’s family and/or friends in 214 LD (57.2%) and 69 LD/VT (63.3%) patients. The benefits lasted 1–3 hours in both groups with the maximum effect after 2 drinks in LD patients (p = 0.002), whereas LD/VT symptoms improved independent of the consumed amount (p = 0.48). Our data suggest that isolated dystonic symptoms, such as in LD, are responsive to alcohol intake and this responsiveness is not attributed to the presence of VT, which is known to have significant benefits from alcohol ingestion. Alcohol may modulate the pathophysiological mechanisms underlying abnormal neurotransmission of γ-aminobutyric acid (GABA) in dystonia and as such provide new avenues for novel therapeutic options in these patients.

    Numerous studies have revealed that study skills have a constructive role on the academic performance of students, in addition to educational quality, student' intelligence, and their affective characteristics. This study aims to examine study skills and the factors influencing them among the health sciences students of Urmia University of Medical Sciences in Iran. This was a cross-sectional study carried out from May to November 2013. A total of 340 Urmia health sciences students were selected using a simple sampling method. Data were collected using the Study Skills Assessment Questionnaire of Counseling Center of Houston University and analyzed with descriptive and analytical statistics. The mean and standard deviation of the students' study skills were 172.5±23.2, out of a total score of 240. Around 1.2% of the study skills were weak; 86.8%, moderate; and 12%, good. Among the study skills, the scores of time management, and memory and concentration were better than the others. Also, there was a significant positive correlation between study skills scores and the students' family housing status and academic level (Pstudy skills, these were not sufficient and far from good. Improving and promoting the study skills of university students require the designing and implementing of education programs for study strategies. Therefore, decision makers and planners in the educational areas of universities should consider the topic described above.

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

    Directory of Open Access Journals (Sweden)

    G. Bianchi

    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.

    1983-04-01

    This report is published as a product of the National Waste Terminal Storage (NWTS) Program. The objective of this program is the development of terminal waste storage facilities in deep stable geologic formations for high-level nuclear wastes, including spent fuel elements from commercial power reactors and transuranic nuclear waste for which the federal government is responsible. This report is part of the location and site characterization phase and contains threatened and endangered species information for the Gibson Dome and Elk Ridge study areas of the Paradox Region. The threatened and endangered species information was obtained through site surveys designed and implemented by area experts. The site surveys were performed during the period late summer 1981 - spring 1982 in the Gibson Dome and Elk Ridge Study Areas. No threatened or endangered species were identified in either Lavender or Davis canyons. Additional studies at the borehole locations in Beef Basin did identify the nearest occurrence of a species proposed for endangered status (Astragalus monumentalis, a monument milkvetch, member of the legume family). The species was identified approximately 160 to 300 m (500 to 1000 ft) from a hydro testing drill site. Consequently, construction and operation activity should not cause any adverse impacts. This report will be used to satisfy Section 7 requirements of the Endangered Species Act (PL 93-205 as amended) and to allow the United States Fish and Wildlife Service to verify that no protected species are subject to disturbance as the result of project activities occurring in the Gibson Dome and Elk Ridge study areas

    Science.gov (United States)

    Bartlett, D L; Ezzati-Rice, T M; Stokley, S; Zhao, Z

    2001-05-01

    The National Immunization Survey (NIS) and the National Health Interview Survey (NHIS) produce national coverage estimates for children aged 19 months to 35 months. The NIS is a cost-effective, random-digit-dialing telephone survey that produces national and state-level vaccination coverage estimates. The National Immunization Provider Record Check Study (NIPRCS) is conducted in conjunction with the annual NHIS, which is a face-to-face household survey. As the NIS is a telephone survey, potential coverage bias exists as the survey excludes children living in nontelephone households. To assess the validity of estimates of vaccine coverage from the NIS, we compared 1995 and 1996 NIS national estimates with results from the NHIS/NIPRCS for the same years. Both the NIS and the NHIS/NIPRCS produce similar results. The NHIS/NIPRCS supports the findings of the NIS.

    Background Monolingual Web survey is a common tool for studying adolescent health. However, national languages may cause difficulties for some immigrant-origin youths, which lower their participation rate. In national surveys, the number of ethnic minority groups is often too small to assess their well-being. Objective We studied the feasibility of a multilingual Web survey targeted at immigrant-origin youths by selection of response language, and compared participation in different language groups with a monolingual survey. Methods The Adolescent Health and Lifestyle Survey (AHLS), Finland, with national languages (Finnish/Swedish) was modified into a multilingual Web survey targeted at a representative sample of 14- and 16-year olds (N=639) whose registry-based mother tongue was other than the national languages. The survey was conducted in 2010 (16-year olds) and 2011 (14-year olds). The response rate of the multilingual survey in 2011 is compared with the AHLS of 2011. We also describe the translation process and the e-form modification. Results Of the respondents, 57.6% answered in Finnish, whereas the remaining 42.4% used their mother tongue (P=.002). A majority of youth speaking Somali, Middle Eastern, Albanian, and Southeast Asian languages chose Finnish. The overall response rate was 48.7% with some nonsignificant variation between the language groups. The response rate in the multilingual Web survey was higher (51.6%, 163/316) than the survey with national languages (46.5%, 40/86) in the same age group; however, the difference was not significant (P=.47). The adolescents who had lived in Finland for 5 years or less (58.0%, 102/176) had a higher response rate than those having lived in Finland for more than 5 years (45.1%, 209/463; P=.005). Respondents and nonrespondents did not differ according to place of birth (Finland/other) or residential area (capital city area/other). The difference in the response rates of girls and boys was nearly significant (P

    This report is a release of digital data from a helicopter electromagnetic and magnetic survey conducted by Fugro Airborne Surveys in areas of eastern Nebraska as part of a joint hydrologic study by the Lower Platte North and Lower Platte South Natural Resources Districts, and the U.S. Geological Survey. The survey flight lines covered 1,418.6 line km (882 line mile). The survey was flown from April 22 to May 2, 2009. The objective of the contracted survey was to improve the understanding of the relation between surface water and groundwater systems critical to developing groundwater models used in management programs for water resources. The electromagnetic equipment consisted of six different coil-pair orientations that measured resistivity at separate frequencies from about 400 hertz to about 140,000 hertz. The electromagnetic data were converted to georeferenced electrical resistivity grids and maps for each frequency that represent different approximate depths of investigation for each survey area. The electrical resistivity data were input into a numerical inversion to estimate resistivity variations with depth. In addition to the electromagnetic data, total field magnetic data and digital elevation data were collected. Data released in this report consist of flight line data, digital grids, digital databases of the inverted electrical resistivity with depth, and digital maps of the apparent resistivity and total magnetic field. The range of subsurface investigation is comparable to the depth of shallow aquifers. The survey areas, Swedeburg and Sprague, were chosen based on results from test flights in 2007 in eastern Nebraska and needs of local water managers. The geophysical and hydrologic information from U.S. Geological Survey studies are being used by resource managers to develop groundwater resource plans for the area.

    This study sought to establish if nurses at a community hospital could correctly identify patients at high risk for skin breakdown and determine whether the resources needed to reposition high-risk patients per protocol were available. The sample comprised 101 registered nurses from 8 acute care units in a 246-bed community-owned district Magnet® hospital. The study facility serves patients from a wide geographic area in the "panhandle" of Idaho with a largely rural population. Face-to-face interviews were conducted on all shifts for 4 days. The instrument consisted of demographic questions and patient assignment questions including which patients the nurse identified at high risk for skin breakdown, which patients the nurse received information on about skin risks at change of shift, whether the nurse knew the Norton Pressure Ulcer Scale scores for their patients, whether patients were repositioned, who performed the repositioning, and how many times that shift. Surveyors obtained patients' Norton scores from computer records and recorded whether the nurse correctly identified patients at high-risk for skin breakdown. Most nurses (73%) stated they did not know their patients' Norton scores. About 60% of nurses reported turning their high-risk patients every 2 to 4 hours. The repositioning was completed most often by RNs alone (39%), RN and CNA (36%), and by patients themselves (35%). Reasons for not repositioning included the following: allowed to sleep, off unit, patient refused, not enough time, family refused, pain, not enough help, and patient receiving end-of-life care. Assessment of patient's skin risk status was correct in 232 out of 348 patients (66%). Nurses predicted high risk when the Norton score indicated low risk in 35.9% of patients and low risk when the Norton scale indicated high risk in 35.1%. Nurses reported receiving information about skin risk in 33% of their assigned patients. Nurses reported adequate resources to reposition patients. Most

    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.

    To determine the self-reported prevalence of domestic violence and associated risk factors in the Sivas province of Turkey. Five hundred and eighty-three households were chosen by the method of stratified random sampling. The average age among women was 28.65+/-4.64. A total of 45.3% of women were in 30-34 age-group, 76.5% were housewives, and 91.2% were married. The data were gathered by performing face-to-face interviews in participants' homes. Demographic data were obtained by fill-in forms. We found a statistically significant relationship among the types of violence and annual income, type of family, education and occupation level of women, education level of perpetrators, watching violent films, and childhood experience of emotional abuse or negligence. Fifty-two percent of women were exposed to at least one type of violence. Verbal violence was the most frequent type of violence (53.8%), followed by physical violence (38.3%). About 45% of women exposed to violence were in the 30-34 age group, 41.6% completed only primary schools, 73.6% were housewives, 91.7% were married, 71.0% had been exposed to violence during their childhood, and 45.2%, had been exposed to violence several times in a month. Economic problems were reported as the most important reason for domestic violence (31.4%). Our study found higher prevalence of domestic violence than expected. As an important public health problem, domestic violence requires a multidisciplinary approach to understand its causes and plan preventive measures.

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

    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.

    In order to study neutron dose measurement in high energy radiation field, a Dual-moderated survey meter in the range from 1 keV to 300 MeV mean energies spectra has been developed. Measurement results of some survey meters depend on the neutron spectra characteristics in different neutron radiation fields, so the characteristics of the responses to various neutron spectra should be studied in order to get more reasonable dose. In this paper the responses of the survey meter were calculated under different neutron spectra data from IAEA of Technical Reports Series No. 318 and other references. Finally one dose estimation method was determined. The range of the reading per H*(10) for the method estimated is about 0.7–1.6 for the neutron mean energy range from 50 keV to 300 MeV. -- Highlights: • We studied a novel high energy neutron survey meter. • Response characteristics of the survey meter were calculated by using a series of neutron spectra. • One significant advantage of the survey meter is that it can provide mean energy of radiation field. • Dose estimate deviation can be corrected. • The range of corrected reading per H*(10) is about 0.7–1.6 for the neutron fluence mean energy range from 0.05 MeV to 300 MeV

  1. Estimating mortality from external causes using data from retrospective surveys: A validation study in Niakhar (Senegal

    2018-03-01

    Full Text Available Background: In low- and middle-income countries (LMICs, data on causes of death is often inaccurate or incomplete. In this paper, we test whether adding a few questions about injuries and accidents to mortality questionnaires used in representative household surveys would yield accurate estimates of the extent of mortality due to external causes (accidents, homicides, or suicides. Methods: We conduct a validation study in Niakhar (Senegal, during which we compare reported survey data to high-quality prospective records of deaths collected by a health and demographic surveillance system (HDSS. Results: Survey respondents more frequently list the deaths of their adult siblings who die of external causes than the deaths of those who die from other causes. The specificity of survey data is high, but sensitivity is low. Among reported deaths, less than 60Š of the deaths classified as due to external causes by the HDSS are also classified as such by survey respondents. Survey respondents better report deaths due to road-traffic accidents than deaths from suicides and homicides. Conclusions: Asking questions about deaths resulting from injuries and accidents during surveys might help measure mortality from external causes in LMICs, but the resulting data displays systematic bias in a rural population of Senegal. Future studies should 1 investigate whether similar biases also apply in other settings and 2 test new methods to further improve the accuracy of survey data on mortality from external causes. Contribution: This study helps strengthen the monitoring of sustainable development targets in LMICs by validating a simple approach for the measurement of mortality from external causes.

    Low front-end cost and rapid accrual make Web-based surveys and enrolment in studies attractive, but participants are often self-selected with little reference to a well-defined study base. Of course, high quality studies must be internally valid (validity of inferences for the sample at hand......), but Web-based enrolment reactivates discussion of external validity (generalization of within-study inferences to a target population or context) in epidemiology and clinical trials. Survey research relies on a representative sample produced by a sampling frame, prespecified sampling process and weighting...

    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.

    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

    Full Text Available Abstract Background Investigators conduct survey studies for a variety of reasons. Poor participant response rates are common, however, and may limit the generalizability and utility of results. The objective of this study was to determine whether direct approach with a tablet device enhances survey study participant response rate and to assess participants’ experiences with this mode of survey administration. Findings An interventional study nested within a single center survey study was conducted at McMaster Children’s Hospital. The primary outcome was the ability to achieve of a survey study response rate of 70% or greater. Eligible participants received 3 email invitations (Week 0, 2, 4 to complete a web-based (Survey Monkey survey. The study protocol included plans for a two-week follow-up phase (Phase 2 where non-responders were approached by a research assistant and invited to complete an iPad-based version of the survey. The Phase 1 response rate was 48.7% (56/115. Phase 2 effectively recruited reluctant responders, increasing the overall response rate to 72.2% (83/115. On a 7-point Likert scale, reluctant responders highly rated their enjoyment (mean 6.0, sd 0.83 [95% CI: 5.7-6.3] and ease of use (mean 6.7, sd 0.47 [95% CI: 6.5-6.9] completing the survey using the iPad. Reasons endorsed for Phase 2 participation included: direct approach (81%, immediate survey access (62%, and the novelty of completing a tablet-based survey (54%. Most reluctant responders (89% indicated that a tablet-based survey is their preferred method of survey completion. Conclusions Use of a tablet-based version of the survey was effective in recruiting reluctant responders and this group reported positive experiences with this mode of survey administration.

  11. Survey of seismic fragilities used in PRA studies of nuclear power plants

    1998-01-01

    In recent years, seismic PRA studies have been performed on a large number of nuclear power plants in the USA. This paper presents a summary of a survey on fragility databases and the range of evaluated fragility values of various equipment categories based on past PRAs. The survey includes the use of experience data, the interpretations of available test data, and the quantification of uncertainties. The surveyed fragility databases are limited to data available in the public domain such as NUREG reports, conference proceedings and other publicly available reports. The extent of the availability of data as well as limitations are studied and tabulated for various equipment categories. The survey of the fragility values in past PRA studies includes not only the best estimate values, but also the dominant failure modes and the estimated uncertainty levels for each equipment category. The engineering judgments employed in estimating the uncertainty in the fragility values are also studied. This paper provides a perspective on the seismic fragility evaluation procedures for equipment in order to clearly identify the engineering analysis and judgment used in past seismic PRA studies

    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.

    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. The objective of the study was to determine the efficacy of study recruitment via social networks versus paid advertising on Facebook. 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. 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. Facebook advertising is a cost-effective means of recruiting parents, a group difficult to reach by other methods.

    We revisit the common standards recommended by Ralph et al. (1993, 1995a) for conducting point-count surveys to assess the relative abundance of landbirds breeding in North America. The standards originated from discussions among ornithologists in 1991 and were developed so that point-count survey data could be broadly compared and jointly analyzed by national data centers with the goals of monitoring populations and managing habitat. Twenty years later, we revisit these standards because (1) they have not been universally followed and (2) new methods allow estimation of absolute abundance from point counts, but these methods generally require data beyond the original standards to account for imperfect detection. Lack of standardization and the complications it introduces for analysis become apparent from aggregated data. For example, only 3% of 196,000 point counts conducted during the period 1992-2011 across Alaska and Canada followed the standards recommended for the count period and count radius. Ten-minute, unlimited-count-radius surveys increased the number of birds detected by >300% over 3-minute, 50-m-radius surveys. This effect size, which could be eliminated by standardized sampling, was ≥10 times the published effect sizes of observers, time of day, and date of the surveys. We suggest that the recommendations by Ralph et al. (1995a) continue to form the common standards when conducting point counts. This protocol is inexpensive and easy to follow but still allows the surveys to be adjusted for detection probabilities. Investigators might optionally collect additional information so that they can analyze their data with more flexible forms of removal and time-of-detection models, distance sampling, multiple-observer methods, repeated counts, or combinations of these methods. Maintaining the common standards as a base protocol, even as these study-specific modifications are added, will maximize the value of point-count data, allowing compilation and

    Full Text Available Purpose - The purpose of this paper is to provide a comprehensive survey of the literature about the use of agent-based simulation (ABS in the study of organizational behavior, decision making, and problem-solving. It aims at contributing to the consolidation of ABS as a field of applied research in management and organizational studies. Design/methodology/approach - The authors carried out a non-systematic search in literature published between 2000 and 2016, by using the keyword “agent-based” to search through Scopus’ business, management and accounting database. Additional search criteria were devised using the papers’ keywords and the categories defined by the divisions and interest groups of the Academy of Management. The authors found 181 articles for this survey. Findings - The survey shows that ABS provides a robust and rigorous framework to elaborate descriptions, explanations, predictions and theories about organizations and their processes as well as develop tools that support strategic and operational decision making and problem-solving. The authors show that the areas that report the highest number of applications are operations and logistics (37 percent, marketing (17 percent and organizational behavior (14 percent. Originality/value - The paper illustrates the increasingly prominent role of ABS in fields such as organizational behavior, strategy, human resources, marketing and logistics. To-date, this is the most complete survey about ABS in all management areas.

    Roughly 10-15% of the general population is affected by tinnitus and this percentage is estimated to rise in future. Because there is currently no cure for tinnitus, treatment is limited and is primarily achieved through management of symptoms and counseling. This study compared audiologists' and patients' responses to related survey questions about their expectations regarding tinnitus treatment. Two separate surveys were created, one for patients with tinnitus, and one for practicing audiologists who may treat such patients. The surveys included several related questions, such that comparison of the two could reveal where patients' and audiologists' expectations for tinnitus care were in agreement and areas in which they differed. The surveys for audiologists and adults with tinnitus were 31- and 38-item questionnaires, respectively. Both surveys comprised demographic questions followed by several tinnitus-related questions in either multiple-choice or Likert-scale format. We received 230 completed Patient Surveys and 68 completed Audiologist Surveys. All survey recruitment was completed online. Responses were collected via the Survey Monkey web tool (http://www.surveymonkey.com/). Responses were analyzed within and between surveys and grouped into topical categories (assessment, counseling, current available tinnitus information, satisfaction and expectations, improving tinnitus management). For data within each survey, descriptive statistics and correlation analyses were used. For selected comparisons between surveys, cross-tabulations were used. Hierarchical regression modeling was conducted to further explore (1) the perceived effectiveness of treatment received, and (2) how each group defined treatment success. Differences were noted between the two groups' responses to the question on the definition of treatment success; audiologists reported decreased awareness (77%), stress/anxiety relief (63%), and increased knowledge of tinnitus (63%) most commonly

    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

    Four user surveys were performed at recycle centres (RCs) in the Municipalities of Aarhus and Copenhagen, Denmark, to get general information on compost use and to examine the substitution of peat, fertiliser and manure by compost in hobby gardening. The average driving distance between the users' households and the RCs was found to be 4.3 km and the average amount of compost picked up was estimated at 800 kg per compost user per year. The application layer of the compost varied (between 1 and 50 cm) depending on the type of use. The estimated substitution (given as a fraction of the compost users that substitute peat, fertiliser and manure with compost) was 22% for peat, 12% for fertiliser and 7% for manure (41% in total) from the survey in Aarhus (n=74). The estimate from the survey in Copenhagen (n=1832) was 19% for peat, 24% for fertiliser and 15% for manure (58% in total). This is the first time, to the authors' knowledge, that the substitution of peat, fertiliser and manure with compost has been assessed for application in hobby gardening. Six case studies were performed as home visits in addition to the Aarhus surveys. From the user surveys and the case studies it was obvious that the total substitution of peat, fertiliser and manure was not 100%, as is often assumed when assigning environmental credits to compost. It was more likely around 50% and thus there is great potential for improvement. It was indicated that compost was used for a lot of purposes in hobby gardening. Apart from substitution of peat, fertiliser and manure, compost was used to improve soil quality and as a filling material (as a substitute for soil). Benefits from these types of application are, however, difficult to assess and thereby quantify. Copyright © 2010 Elsevier Ltd. All rights reserved.

    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.

    Aim: Using the data from graduate surveys, this study aims to analyze which factors related to teaching and learning at the Freiburg Faculty of Medicine can influence study success. Background: Study success and the factors influencing it have long been the subject of investigation, with study success being measured in terms of easily quantifiable indicators (final grades, student satisfaction, etc.). In recent years, it has also frequently been assessed in terms of graduate competency levels. Graduate surveys are considered suitable instruments for measuring these dimensions of study success. Method: Data from three Freiburg graduate surveys conducted one and a half years after graduation were drawn upon for the analysis. Study success was operationalized using four indicators: results on the written section of the M2 exam, self-assessment of medical expertise and scientific expertise, and student satisfaction. Using multiple regression analyses, the predictive power was calculated for selected variables, also measured by the graduate surveys, for the different study success indicators. Results: It was possible to identify models that contribute slightly or moderately to the prediction of study success. The score earned on the university entrance qualification demonstrated itself to be the strongest predictor for forecasting the M2 written exam: R2 is between 0.08 and 0.22 for the three surveys. Different variables specific to degree program structure and teaching are helpful for predicting medical expertise (R2=0.04-0.32) and student satisfaction (R2=0.12-0.35). The two variables, structure and curricular sequencing of the degree program and combination of theory and practice, show themselves to be significant, sample-invariant predictors (β-weightStructure=0.21-0.58, β-weightCombination=0.27-0.56). For scientific expertise, no sample-independent predictors could be determined. Conclusion: Factors describing teaching hardly provide any assistance when

    A survey of literature in the title was performed to know the actual status of the dispersion from excretion and expiration studies of radioisotopes since, at present, the probable dispersion ratio is assumed to be 100% in calculation for legally permitted use of radioisotopes which conceivably being far from the real status and being incompatible with the guideline for pharmacokinetic studies requiring the recovery of >95% of dosed radioactivity in balance study. There are two interpretations for the dispersion; it is the expiration ratio and it is the fraction unrecovered. Survey was done on 11 Japanese and foreign journals in 1985-1996 publishing most of pharmacokinetic studies and on 650 compounds in 358 facilities with 1,975 experiments in total. In those experiments, the total recovery of radioactivity was 95% in average, unrecovered fraction, 5% and expiration ratio, 2%. As for unclide, 14 C, 3 H, 125 I and 35 S were surveyed since they occupied 99.4% of the experiments and their dispersion was <5%. Rats were used in 70% of the experiments and the dispersion in all animal experiments was about 5%. Administration route was regardless of the dispersion. (K.H.)

    Objective To optimize and simplify the survey method of Oncomelania hupensis snails in marshland endemic regions of schistosomiasis, so as to improve the precision, efficiency and economy of the snail survey. Methods A snail sampling strategy (Spatial Sampling Scenario of Oncomelania based on Plant Abundance, SOPA) which took the plant abundance as auxiliary variable was explored and an experimental study in a 50 m×50 m plot in a marshland in the Poyang Lake region was performed. Firstly, the push broom surveyed data was stratified into 5 layers by the plant abundance data; then, the required numbers of optimal sampling points of each layer through Hammond McCullagh equation were calculated; thirdly, every sample point in the line with the Multiple Directional Interpolation (MDI) placement scheme was pinpointed; and finally, the comparison study among the outcomes of the spatial random sampling strategy, the traditional systematic sampling method, the spatial stratified sampling method, Sandwich spatial sampling and inference and SOPA was performed. Results The method (SOPA) proposed in this study had the minimal absolute error of 0.213 8; and the traditional systematic sampling method had the largest estimate, and the absolute error was 0.924 4. Conclusion The snail sampling strategy (SOPA) proposed in this study obtains the higher estimation accuracy than the other four methods.

  1. Using expert opinion surveys to rank threats to endangered species: a case study with sea turtles.

    Little is known about how specific anthropogenic hazards affect the biology of organisms. Quantifying the effect of regional hazards is particularly challenging for species such as sea turtles because they are migratory, difficult to study, long lived, and face multiple anthropogenic threats. Expert elicitation, a technique used to synthesize opinions of experts while assessing uncertainty around those views, has been in use for several decades in the social science and risk assessment sectors. We conducted an internet-based survey to quantify expert opinion on the relative magnitude of anthropogenic hazards to sea turtle populations at the regional level. Fisheries bycatch and coastal development were most often ranked as the top hazards to sea turtle species in a geographic region. Nest predation and direct take followed as the second and third greatest threats, respectively. Survey results suggest most experts believe sea turtles are threatened by multiple factors, including substantial at-sea threats such as fisheries bycatch. Resources invested by the sea turtle community, however, appear biased toward terrestrial-based impacts. Results from the survey are useful for conservation planning because they provide estimates of relative impacts of hazards on sea turtles and a measure of consensus on the magnitude of those impacts among researchers and practitioners. Our survey results also revealed patterns of expert bias, which we controlled for in our analysis. Respondents with no experience with respect to a sea turtle species tended to rank hazards affecting that sea turtle species higher than respondents with experience. A more-striking pattern was with hazard-based expertise: the more experience a respondent had with a specific hazard, the higher the respondent scored the impact of that hazard on sea turtle populations. Bias-controlled expert opinion surveys focused on threatened species and their hazards can help guide and expedite species recovery plans.

    2018-01-01

    The rapid and wide-reaching expansion of internet access and digital technologies offers epidemiologists numerous opportunities to study health behaviors. One particularly promising new data collection strategy is the use of Facebook’s advertising platform in conjunction with Web-based surveys. Our research team at the Center for Technology and Behavioral Health has used this quick and cost-efficient method to recruit large samples and address unique scientific questions related to cannabis use. In conducting this research, we have gleaned several insights for using this sampling method effectively and have begun to document the characteristics of the resulting data. We believe this information could be useful to other researchers attempting to study cannabis use or, potentially, other health behaviors. The first aim of this paper is to describe case examples of procedures for using Facebook as a survey sampling method for studying cannabis use. We then present several distinctive features of the data produced using this method. Finally, we discuss the utility of this sampling method for addressing specific types of epidemiological research questions. Overall, we believe that sampling with Facebook advertisements and Web surveys is best conceptualized as a targeted, nonprobability-based method for oversampling cannabis users across the United States.

Overall, we believe that sampling with Facebook advertisements and Web surveys is best conceptualized as a targeted, nonprobability-based method for oversampling cannabis users across the United States. ©Jacob T Borodovsky, Lisa A Marsch, Alan J Budney.

    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

    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. 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. 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 program. The mapping data will also be used for overviewing

    This study aimed to develop a family-centered care survey for Chinese adult intensive care units and to establish the survey's psychometric properties. Family-centered care (FCC) is widely recognized as an ideal model of care. Few studies have explored FCC perceptions among family members of adult critical care patients in Asian countries, and no Chinese FCC measurement has been developed. An English version of the 3-factor family-centered care survey for adult intensive care units (FCCS-AICU) was translated into Chinese using a modified back translation procedure. Based on the literature review, two additional concepts, information and empowerment, were added to the Chinese FCCS-AICU. The psychometric properties of the Chinese FCCS-AICU were determined with 249 family members from a medical center in Taiwan and were tested for construct and convergent validity, and internal consistency. Both the monolingual and bilingual equivalence tests of the English and Chinese versions of the 3-factor FCCS-AICU were supported. Exploratory factor analysis supported the 5-factor structure of the Chinese FCCS-AICU with a total explained variance of 58.34%. The Chinese FCCS-AICU was correlated with the Chinese Critical Care Family Needs Inventory. Internal consistency, determined by Cronbach's α, for the overall scale was .94. The Chinese FCCS-AICU is a valid and reliable tool for measuring perceptions of FCC by family members of adult intensive care patients within Chinese-speaking communities.

  13. User-needs study for the 1993 residential energy consumption survey

    Energy Technology Data Exchange (ETDEWEB)

    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.

    In health care simulation, simulation technicians perform multiple tasks to support various educational offerings. Technician responsibilities and the tasks that accompany them seem to vary between centers. The objectives were to identify the range and frequency of tasks that technicians perform and to determine if there is a correspondence between what technicians do and what they feel their responsibilities should be. We hypothesized that there is a core set of responsibilities and tasks for the technician position regardless of background, experience, and type of simulation center. We conducted a prospective, survey-based study of individuals currently functioning in a simulation technician role in a simulation center. This survey was designed internally and piloted within 3 academic simulation centers. Potential respondents were identified through a national mailing list, and the survey was distributed electronically during a 3-week period. A survey request was sent to 280 potential participants, 136 (49%) responded, and 73 met inclusion criteria. Five core tasks were identified as follows: equipment setup and breakdown, programming scenarios into software, operation of software during simulation, audiovisual support for courses, and on-site simulator maintenance. Independent of background before they were hired, technicians felt unprepared for their role once taking the position. Formal training was identified as a need; however, the majority of technicians felt experience over time was the main contributor toward developing knowledge and skills within their role. This study represents a first step in defining the technician role within simulation-based education and supports the need for the development of a formal job description to allow recruitment, development, and certification.

    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.

    Knowing the baseline level of radioactivity in areas naturally enriched in radionuclides is important in the uranium mining context to assess radiation doses to humans and the environment both during and after mining. This information is particularly useful in rehabilitation planning and developing closure criteria for uranium mines as only radiation doses additional to the natural background are usually considered ‘controllable’ for radiation protection purposes. In this case study we have tested whether the method of contemporary groundtruthing of a historic airborne gamma survey could be used to determine the pre-mining radiological conditions at the Ranger mine in northern Australia. The airborne gamma survey was flown in 1976 before mining started and groundtruthed using ground gamma dose rate measurements made between 2007 and 2009 at an undisturbed area naturally enriched in uranium (Anomaly 2) located nearby the Ranger mine. Measurements of 226 Ra soil activity concentration and 222 Rn exhalation flux density at Anomaly 2 were made concurrent with the ground gamma dose rate measurements. Algorithms were developed to upscale the ground gamma data to the same spatial resolution as the historic airborne gamma survey data using a geographic information system, allowing comparison of the datasets. Linear correlation models were developed to estimate the pre-mining gamma dose rates, 226 Ra soil activity concentrations, and 222 Rn exhalation flux densities at selected areas in the greater Ranger region. The modelled levels agreed with measurements made at the Ranger Orebodies 1 and 3 before mining started, and at environmental sites in the region. The conclusion is that our approach can be used to determine baseline radiation levels, and provide a benchmark for rehabilitation of uranium mines or industrial sites where historical airborne gamma survey data are available and an undisturbed radiological analogue exists to groundtruth the data. - Highlights:

    Several influential aspects of survey research have been under-investigated and there is a lack of guidance on reporting survey studies, especially web-based projects. In this review, we aim to investigate the reporting practices and quality of both web- and non-web-based survey studies to enhance the quality of reporting medical evidence that is derived from survey studies and to maximize the efficiency of its consumption. Reporting practices and quality of 100 random web- and 100 random non-web-based articles published from 2004 to 2016 were assessed using the SUrvey Reporting GuidelinE (SURGE). The CHERRIES guideline was also used to assess the reporting quality of Web-based studies. Our results revealed a potential gap in the reporting of many necessary checklist items in both web-based and non-web-based survey studies including development, description and testing of the questionnaire, the advertisement and administration of the questionnaire, sample representativeness and response rates, incentives, informed consent, and methods of statistical analysis. Our findings confirm the presence of major discrepancies in reporting results of survey-based studies. This can be attributed to the lack of availability of updated universal checklists for quality of reporting standards. We have summarized our findings in a table that may serve as a roadmap for future guidelines and checklists, which will hopefully include all types and all aspects of survey research.

    Purpose: A review of the Patterns of Care Studies Process Survey data on carcinoma of the cervix conducted on patients in 1978, 1983, and 1988-89 was carried out to identify changes or trends in the demographics, evaluation, and treatment that might have occurred over this time period. Methods and Materials: Patterns of Care Studies conducted surveys on patients treated by radiation therapy for cervical carcinoma in 1978, 1983, and 1988-89. These surveys have compiled demographic and treatment data on a total of 993 patients. There is outcome data for the 1978 and 1983 surveys, but not for the 1988-89 survey because follow-up has not been collected yet. The demographic and treatment delivery data on all three surveys has been reviewed and analyzed and is the subject of this study. Results: There was no difference in the age distribution at the time of diagnosis of the patients in these surveys. The percentage of black patients remained constant in the three surveys, 19%, 17%, and 21%, respectively. The percentage of white patients was 76%, 78%, and 67%, but that of nonwhite/nonblack patients was 3%, 4%, and 12% (p 60 Co units decreased from 35 to 2% from the first to the third survey [6 to 0% for short source-surface distance (SSD) 60 Co units]. Point dose calculations for the intracavitary therapy increased from 78% in the 1978 survey to 95% in the third survey. As determined by the total dose delivered to the paracentral points, more patients (75.1%) were treated according to the Patterns of Care recommended guidelines in the 1988-89 survey than in the 1983 survey (63.6%). Chemotherapy was given to 12% of the patients undergoing radiation therapy during the period of the third survey, but these data are not available for the first and second surveys. Conclusion: Review of the Carcinoma of the Cervix Patterns of Care studies discloses significant changes in the demographics, patient evaluation, and radiation therapy techniques during the period of the studies.

    The number of operative procedures involving the creation of an intestinal stoma is likely to increase as the population ages. Understanding the role of age on postoperative outcomes such as quality of life (QoL) and self-efficacy is critical to developing appropriate supportive strategies. A descriptive survey study was conducted among 18 patients (11 men seven women, age range 47 to 90 years) who had an intestinal ostomy created during a 3-year period at the University of Alberta Hospital in Edmonton, Alberta, Canada. The Stoma Quality of Life Survey and a self-efficacy survey examining self-care, activities of daily living, and instrumental activities of daily living were administered. Patient records were obtained through a retrospective chart review; of the 57 patients identified, 18 were still alive, had not undergone stoma reversal, were cognitively competent, and agreed to participate. Seven patients were stoma since 2009, four patients since 2010, and 10 patients since 2011. Although older patients had more comorbidities and higher mortality following the surgery (46.1% for patients >65 versus 26.1%, for patients stoma-associated QoL and self-efficacy scores. In patients who had stoma surgery in 2011, older patients on average had higher QoL scores (65.21 versus 61.87, maximum score 100, P = 0.56), but lower self-efficacy scores (32.50 versus 35.25, maximum score 40, P = 0.50). These findings are similar to previously reported study results. However, the small study sample size limits analysis of the variables that may affect QoL in stoma patients. This study supports the need for additional prospective studies to help clinicians develop effective support strategies.

    Performing 'good work' in either neurosurgery or neuroscience alone is a challenge. Despite this, a large number of neurosurgeons divide their careers between the two fields, and attempt to excel in both arenas simultaneously. The purpose of this study is to explore perceptions on whether it is possible to do good work in both neurosurgery and research simultaneously, or whether one field suffers at the expense of the other. This question was put to practicing neurosurgeons via an electronic survey that was distributed to resident and staff neurosurgeons in Canada. 54 surgeons completed the survey, 32 of whom were current or intended neurosurgeon-scientists. Themes explored through the survey included motives behind the pursuit or absence of research in one's neurosurgical career, the quality and feasibility of a dual career, and alternatives to one individual assuming a dual role. The opinions obtained revealed that it is possible to do good work in both neurosurgery and neuroscience simultaneously, but in reality it is very difficult to do. Alternatives to this dual career, such as collaboration between clinical neurosurgeons and pure scientists for example, may help bridge the gap between clinical and research arenas.

    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.

    Recruiting hard-to-reach populations for health research is challenging. Web-based platforms offer one way to recruit specific samples for research purposes, but little is known about the feasibility of online recruitment and the representativeness and comparability of samples recruited through different Web-based platforms. The objectives of this study were to determine the feasibility of recruiting a hard-to-reach population (pregnant smokers) using 4 different Web-based platforms and to compare participants recruited through each platform. A screener and survey were distributed online through Qualtrics Panel, Soapbox Sample, Reddit, and Amazon Mechanical Turk (mTurk). Descriptive statistics were used to summarize results of each recruitment platform, including eligibility yield, quality yield, income, race, age, and gestational age. Of the 3847 participants screened for eligibility across all 4 Web-based platforms, 535 were eligible and 308 completed the survey. Amazon mTurk yielded the fewest completed responses (n=9), 100% (9/9) of which passed several quality metrics verifying pregnancy and smoking status. Qualtrics Panel yielded 14 completed responses, 86% (12/14) of which passed the quality screening. Soapbox Sample produced 107 completed surveys, 67% (72/107) of which were found to be quality responses. Advertising through Reddit produced the highest completion rate (n=178), but only 29.2% (52/178) of those surveys passed the quality metrics. We found significant differences in eligibility yield, quality yield, age, number of previous pregnancies, age of smoking initiation, current smokers, race, education, and income (Precruited pregnant smokers, results varied in quality, cost, and percentage of complete responses. Moving forward, investigators should pay careful attention to the percentage yield and cost of online recruitment platforms to maximize internal and external validity. ©Jose Luis Ibarra, Jessica Marie Agas, Melissa Lee, Julia Lily Pan, Alison

  4. Detecting Foci of Malaria Transmission with School Surveys: A Pilot Study in the Gambia.

    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.

    The Internet is increasingly being used as a data collection medium to access research participants. This paper reports on the experience and value of using web-survey software to conduct an eDelphi study to develop Australian critical care course graduate practice standards. The eDelphi technique used involved the iterative process of administering three rounds of surveys to a national expert panel. The survey was developed online using SurveyMonkey. Panel members responded to statements using one rating scale for round one and two scales for rounds two and three. Text boxes for panel comments were provided. For each round, the SurveyMonkey's email tool was used to distribute an individualized email invitation containing the survey web link. The distribution of panel responses, individual responses and a summary of comments were emailed to panel members. Stacked bar charts representing the distribution of responses were generated using the SurveyMonkey software. Panel response rates remained greater than 85% over all rounds. An online survey provided numerous advantages over traditional survey approaches including high quality data collection, ease and speed of survey administration, direct communication with the panel and rapid collation of feedback allowing data collection to be undertaken in 12 weeks. Only minor challenges were experienced using the technology. Ethical issues, specific to using the Internet to conduct research and external hosting of web-based software, lacked formal guidance. High response rates and an increased level of data quality were achieved in this study using web-survey software and the process was efficient and user-friendly. However, when considering online survey software, it is important to match the research design with the computer capabilities of participants and recognize that ethical review guidelines and processes have not yet kept pace with online research practices.

    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.

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 undertaking future

    Stroke is one of the most common causes of physical disability, and early, intensive, and repetitive rehabilitation exercises are crucial to the recovery of stroke survivors. Unfortunately, research shows that only one third of stroke patients actually perform recommended exercises at home, because of the repetitive and mundane nature of conventional rehabilitation exercises. Thus, to motivate stroke survivors to engage in monotonous rehabilitation is a significant issue in the therapy process. Game-based rehabilitation systems have the potential to encourage patients continuing rehabilitation exercises at home. However, these systems are still rarely adopted at patients' places. Discovering and eliminating the obstacles in promoting game-based rehabilitation at home is therefore essential. For this purpose, we conducted a study to collect and analyze the opinions and expectations of stroke patients and clinical therapists. The study is composed of 2 parts: Rehab-preference survey - interviews to both patients and therapists to understand the current practices, challenges, and expectations on game-based rehabilitation systems; and Rehab-compatibility survey - a gaming experiment with therapists to elaborate what commercial games are compatible with rehabilitation. The study is conducted with 30 outpatients with stroke and 19 occupational therapists from 2 rehabilitation centers in Taiwan. Our surveys show that game-based rehabilitation systems can turn the rehabilitation exercises more appealing and provide personalized motivation for various stroke patients. Patients prefer to perform rehabilitation exercises with more diverse and fun games, and need cost-effective rehabilitation systems, which are often built on commodity hardware. Our study also sheds light on incorporating the existing design-for-fun games into rehabilitation system. We envision the results are helpful in developing a platform which enables rehab-compatible (i.e., existing, appropriately

    Full Text Available Abstract Background The purpose of this study was to determine whether the National Health Interview Survey is a useful source to identify informative families for genetic studies of birth defects. Methods The 1994/1995 National Health Interview Survey (NHIS was used to identify households where individuals with two or more birth defects reside. Four groups of households were identified: 1 single non-familial (one individual with one birth defect; 2 single familial (more than one individual with one birth defect; 3 multiple non-familial (one individual with more than one birth defect, and 4 multiple familial (more than one individual with more than one birth defect. The March 2000 U.S. Census on households was used to estimate the total number of households in which there are individuals with birth defects. Results Of a total of 28,094 households and surveyed about birth defects and impairments, 1,083 single non-familial, 55 multiple non-familial, 54 single familial, and 8 multiple familial households were identified. Based on the 2000 U.S. census, it is estimated that there are 4,472,385 households where at least one person has one birth defect in the United States and in 234,846 of them there are at least two affected individuals. Western states had the highest prevalence rates. Conclusions Population-based methods, such as the NHIS, are modestly useful to identify the number and the regions where candidate families for genetic studies of birth defects reside. Clinic based studies and birth defects surveillance systems that collect family history offer better probability of ascertainment.

    Full Text Available Twenty-one standardized non-repeated 1-5 rank order questionnaires were administered to 480 students from twelve districts of Nepal. Twenty-four schools (12 governments and 12 private and ten boys and ten girls of average level from each school were chosen randomly for the survey. The questionnaires covered the six different areas of studies e.g. foundation of the study, hardworking, interpersonal relationship, study habits, study skills and study related problems. This study found noticeable similarities and differences in various issues related to study habit among government and private schools students. About 50 percent Nepalese students like to study in silent and free of an interrupted room. For 36.25 percent Nepalese students qualified teachers and effective teaching methods are the major factors that determine the effective study habits. About 28.95 percent Nepalese students believe that aim and future vision is the key motivating factors for the effective study habits . According to the 36.04 percent Nepalese students the major problems they are facing in the school is unhygienic environment . About 36.87 percent Nepalese students believe that encouragement from the teachers and parents play an important role to proceed ahead even in repeated failure (Table-5. About 39.58 percent Nepalese students are eagerly seeking to be counseled how they can improve their study habits. The survey has found that most of the Nepalese students spend daily two to three hours for the house related works. They should know how to invest their time according to the importance of the task .

    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

    An acoustic modelling study was conducted to examine seismic survey noise propagation in the Queen Charlotte Basin (QCB) and better understand the physical aspects of sound transmission. The study results are intended to help determine the potential physiological and behavioural effects of airgun noise on marine mammals and fish. The scope of the study included a numerical simulation of underwater sound transmission in QCB in areas where oil and gas exploration activities may be conducted; a forecast of received noise levels by combining acoustic transmission loss computations with acoustic source levels representative of seismic exploration activity and, the use of received forecasts to estimate zones of impact for marine mammals. The critical environmental parameters in the QCB are the bathymetry of the ocean, the sound speed profile in the water and the geoacoustic profile of the seabed. The RAM acoustic propagation model developed by the United States Naval Research Laboratory was used to compute acoustic transmission loss in the QCB. The source level and directionality of the seismic array was determined by a full-waveform array source signature model. This modelling study of noise propagation from seismic surveys revealed several key findings. Among them, it showed that received noise levels in the water are affected by the source location, array orientation and the shape of the sound speed profile with respect to water depth. It also showed that noise levels are lowest in shallow bathymetry. 30 refs., 5 tabs., 13 figs.

    Full Text Available Introduction: In the last several decades, South Korea has rapidly adopted Western customs and practices. Yet, cultural differences between South Korea and the United States exist. The purpose ofthis study was to identify and characterize potential cultural differences in the Korean and US institutional review board (IRB approach to certain topics.Methods: A qualitative analysis of a 9-item survey, describing 4 research study case scenarios, sent to IRB members from the United States and South Korea. The case scenarios involved the followingissues: (1 the need for consent for retrospective chart review when research subjects receive their care after the study is conceived; (2 child assent; (3 individual versus population benefit; and (4 exception from informed consent in emergency resuscitation research. The free-text responses were analyzed and abstracted for recurrent themes.Results: Twenty-three of the 45 survey recipients completed the survey, for an overall response rate of 51%. The themes that emerged were as follows: (1 the importance of parental authority among Korean participants versus the importance of child autonomy and child assent among US participants; (2 the recognition of the rights of a proxy or surrogate who can represent an individual’s values by all participants; and (3 the importance of the community, expressed by the Korean respondents, versus individualism, expressed by US respondents.Conclusion: Whereas US participants appear to emphasize the importance of the individual and the autonomy of a child, the Korean respondents stressed the importance of parental authority andbenefiting the community, above and beyond that of the individual person. However, there was substantial overlap in the themes expressed by respondents from both countries.

    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

    Contingency management (CM) has not been thoroughly evaluated as a treatment for alcohol abuse or dependence, in part because verification of alcohol use reduction requires frequent in-person breath tests. Transdermal alcohol sensors detect alcohol regularly throughout the day, providing remote monitoring and allowing for rapid reinforcement of reductions in use. The purpose of this study was to evaluate the efficacy of CM for reduction in alcohol use, using a transdermal alcohol sensor to provide a continuous measure of alcohol use. Participants were 13 heavy drinking adults who wore the Secure Continuous Remote Alcohol Monitoring (SCRAM) bracelet for three weeks and provided reports of alcohol and drug use using daily web-based surveys. In Week 1, participants were asked to drink as usual; in Weeks 2 and 3, they were reinforced on an escalating schedule with values ranging from $5 to $17 per day on days when alcohol use was not reported or detected by the SCRAM. Self-reports of percent days abstinent and drinks per week, and transdermal measures of average and peak transdermal alcohol concentration and area under the curve declined significantly in Weeks 2-3. A nonsignificant but large effect size for reduction in days of tobacco use also was found. An adjustment to the SCRAM criteria for detecting alcohol use provided an accurate but less conservative method for use with non-mandated clients. Results support the efficacy of CM for alcohol use reductions and the feasibility of using transdermal monitoring of alcohol use for clinical purposes. Copyright © 2011 Elsevier Ireland Ltd.

    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

    A survey of studies on ignition and burn of inertial fusion fuels is presented. Potentials and issues of different approaches to ignition (central ignition, fast ignition, volume ignition) are addressed by means of simple models and numerical simulations. Both equimolar DT and T-lean mixtures are considered. Crucial issues concerning hot spot formation (implosion symmetry for central ignition; igniting pulse parameters for fast ignition) are briefly discussed. Recent results concerning the scaling of the ignition energy with the implosion velocity and constrained gain curves are also summarized.

    Full Text Available The Norwegian prison inmates are burdened by problems before they enter prison. Few studies have managed to assess this burden and relate it to what occurs for the inmates once they leave the prison. The Norwegian Offender Mental Health and Addiction (NorMA study is a large-scale longitudinal cohort study that combines national survey and registry data in order to understand mental health, substance use, and criminal activity before, during, and after custody among prisoners in Norway. The main goal of the study is to describe the criminal and health-related trajectories based on both survey and registry linkage information. Data were collected from 1,499 inmates in Norwegian prison facilities during 2013–2014. Of these, 741 inmates provided a valid personal identification number and constitute a cohort that will be examined retrospectively and prospectively, along with data from nationwide Norwegian registries. This study describes the design, procedures, and implementation of the ongoing NorMA study and provides an outline of the initial data.

    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.

    Since the publication in 1973 of the Agency's Market Survey of the economic potential of nuclear power in developing countries, additional studies have continued to predict more realistically this aspect of electrical growth. An updating was prepared in 1974 to reflect the precipitous increase in crude oil prices. Actual forecasts in studies of individual countries are continuing, based on more extensive analysis and the latest economic factors. These studies have been performed for Pakistan, Bangladesh, Indonesia and Hong Kong. A new forecast is presented for certain developing countries in Africa, America and Asia, which gives a range of 250-400 GW(e) of nuclear capacity installed by the end of this century. The lower forecast is considered most likely and represents approximately 30% of the total installed electrical capacity of these countries. (author)

    The American Academy of Dermatology recommends dermatologists understand the costs of dermatologic care. This study sought to measure dermatology providers' understanding of the cost of dermatologic care and how those costs are communicated to patients. We also aimed to understand the perspectives of patients and dermatological trainees on how cost information enters into the care they receive or provide. Surveys were systematically developed and distributed to 3 study populations: dermatology providers, residents, and patients. Response rates were over 95% in all 3 populations. Dermatology providers and residents consistently underestimated the costs of commonly recommended dermatologic medications but accurately predicted the cost of common dermatologic procedures. Dermatology patients preferred to know the cost of procedures and medications, even when covered by insurance. In this population, the costs of dermatologic medications frequently interfered with patients' ability to properly adhere to prescribed regimens. The surveyed population was limited to the northwestern United States and findings may not be generalizable. Cost estimations were based on average reimbursement rates, which vary by insurer. Improving dermatology providers' awareness and communication of the costs of dermatologic care might enhance medical decision-making, improve adherence and outcomes, and potentially reduce overall health care expenditures.

    Evaluating chemical exposures from consumer products is an essential part of chemical safety assessments under REACH and may also be important to demonstrate compliance with consumer product legislation. Modelling of consumer exposure needs input information on the substance (e.g. vapour pressure), the product(s) containing the substance (e.g. concentration) and on consumer behaviour (e.g. use frequency and amount of product used). This feasibility study in Germany investigated methods for conducting a consumer survey in order to identify and retrieve information on frequency, duration, use amounts and use conditions for six example product types (four mixtures, two articles): hand dishwashing liquid, cockpit spray, fillers, paints and lacquers, shoes made of rubber or plastic, and ball-pens/pencils. Retrospective questionnaire methods (Consumer Product Questionnaire (CPQ), and Recall-Foresight Questionnaire (RFQ)) as well as protocol methods (written reporting by participants and video documentation) were used. A combination of retrospective questionnaire and written protocol methods was identified to provide valid information in a resource-efficient way. Relevant information, which can readily be used in exposure modelling, was obtained for all parameters and product types investigated. Based on the observations in this feasibility study, recommendations are given for designing a large consumer survey.

    The aim of this study is to understand the motivating factors behind students' choices in their decision-making process and also get an insight on their perception of different engineering branches. A survey was prepared and the results were evaluated amongst 1163 answers. Two major influences on student's decision in their professional choices are shown to be career services and family members. Generally, students have claimed to choose a profession based on 'finding a job' and 'being happy'. Some engineering branches such as Genetic and Bioengineering, Chemical Engineering, Environmental Engineering and Industrial Engineering, are shown to be distinctly preferred by female students, whereas mechanical, civil and electronic engineering are favourites for male students. The survey results were also compared with the distribution of male and female students in various engineering departments. This study clearly shows that certain engineering branches are perceived as more appropriate for women and are thus favoured by female students, while those perceived as more appropriate for men are favoured by male students.

    The interviewing study data in the title were initially contained in the official request of Hiroshima City and Prefecture, which had been presented to MHLW (Ministry of Health, Labor and Welfare) in 2010, concerning spread of previously defined A-bomb exposed regions and were statistically reanalyzed based on the requirement of the consequent MHLW council. The data were originally derived from the questionnaire in 2008 about the health attitude survey by Hiroshima authorities, from which 892 survivors had received the interview together with self-writing, and answers of 869 parsons (524 males) were finally subjected to the present reanalysis. Measures of the interview involved the SF-36 (Medical Outcome Study Short Form 36-item Health Survey) for QOL, GHQ28 (General Health Questionnaire 28-item) for screening of neurosis/depression, and CAPS (Clinician Administered PTSD Scale) for diagnosis of PTSD (post traumatic stress disorder), etc. These measures were analyzed along with classes of A-bomb experience with adjustment factors of sex, age and income by multiple-/multivariate logistic-regression. It was found that measures were tended to be worse in groups experiencing the black rain without effects of adjustment factors, which was similar to groups experiencing the heavier rainfall; however, these results were statistically insignificant.

    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.

    Multidetector CT (MDCT) scanners have contributed to the widespread use of CT in paediatric imaging. However, concerns are raised for the associated radiation exposure. Very few surveys on radiation exposure from MDCT studies in children are available. The aim of this study was to outline the status of radiation exposure in children from MDCT practice in Italy. In this retrospective multicentre study we asked Italian radiology units with an MDCT scanner with at least 16 slices to provide dosimetric and acquisition parameters of CT examinations in three age groups (1-5, 6-10, 11-15 years) for studies of head, chest and abdomen. The dosimetric results were reported in terms of third-quartile volumetric CT dose index (CTDI{sub vol}) (mGy), size-specific dose estimate (SSDE) (mGy), dose length product (DLP) (mGy cm), and total DLP for multiphase studies. These results were compared with paediatric European and adult Italian published data. A multivariate analysis assessed the association of CTDI{sub vol} with patient characteristics and scanning modalities. We collected data from 993 MDCT examinations performed at 25 centres. For age groups 1-5 years, 6-10 years and 11-15 years, the CTDI{sub vol}, DLP and total DLP values were statistically significantly below the values observed in our analogous national survey in adults, although the difference decreased with increasing age. CTDI{sub vol} variability among centres was statistically significant (variance = 0.07; 95% confidence interval = 0.03-0.16; P < 0.001). This study reviewed practice in Italian centres performing paediatric imaging with MDCT scanners. The variability of doses among centres suggests that the use of standardised CT protocols should be encouraged. (orig.)

    The objective of this work is to support the establishment of a methodology for gamma radiation survey over large areas in order to estimate public exposure to natural background radiation in Brazil. In a first stage, two different sites close to large water bodies were chosen, Guanabara Bay, RJ and Amazon River close to Santarem, PA. Early results showed similar results for over water surveys despite the type of water body. Dose rates over land are higher than those over water, due to the natural radioactivity on soil, pavements and other building materials. In this study the focus was on variability of measurements performed in the same area and variability for different types of area, including roads and urbanized environments. Several measurements have been performed of several areas, that included roads and towns in Para, Bahia, Rio de Janeiro and Minas Gerais. Measurements were done by car and on boats, using a AT6101C Scanner - Spectral Radiation Scanner. Differences were detected for different areas, with roads generally presenting lower dose rates than highly urbanized areas. Also, for roads close to granite rocks and mountains, dose rates are higher than those at both coastal areas and inland lowlands. Large towns present large variability, with individual measurements close to average dose rates from anomalous uranium sites. The results will be used to derive a methodology for assessing background radiation exposure for the Brazilian population. It can be concluded that surveys are to be based on population distribution grids rather than on a simple area based grid distribution, due to both the uneven population distribution and the variability on external dose rates throughout the Brazilian territory.

While organizations strive to reduce readmissions, another important related metric is patient quality of life (QoL. Aims: To compare the relationship between QoL in patients enrolled in the Mayo Clinic Care Transitions (MCCT program versus usual care, and to determine if QoL changed in MCCT participants between baseline and 1-year follow-up. Methods: A baseline survey was mailed to MCCT enrollees in March 2013. Those who completed a baseline survey were sent a follow-up survey 1 year later. A cross-sectional survey of usual care participants was mailed in November 2013. We included in our analysis 199 participants (83 in the MCCT and 116 in usual care aged over 60 years with multiple comorbidities and receiving primary care. Primary outcomes were self-rated QoL; secondary outcomes included self-reported general, physical, and mental health. Intra- and intergroup comparisons of patients were evaluated using Pearson’s chi-squared analysis. Results: MCCT participants had more comorbidities and higher elder risk assessment scores than those receiving usual care. At baseline, 74% of MCCT participants reported responses of good-to-excellent QoL compared to 64% after 1 year (P=0.16. Between MCCT and usual care, there was no significant difference in self-reported QoL (P=0.21. Between baseline and follow-up in MCCT patients, and compared to usual care, there were no significant

    Full Text Available Workaholism has become an increasingly popular area for empirical study. However, most studies examining the prevalence of workaholism have used non-representative samples and measures with poorly defined cut-off scores. To overcome these methodological limitations, a nationally representative survey among employees in Norway (N = 1,124 was conducted. Questions relating to gender, age, marital status, caretaker responsibility for children, percentage of full-time equivalent, and educational level were asked. Workaholism was assessed by the use of a psychometrically validated instrument (i.e., Bergen Work Addiction Scale. Personality was assessed using the Mini-International Personality Item Pool. Results showed that the prevalence of workaholism was 8.3% (95% CI  = 6.7-9.9%. An adjusted logistic regression analysis showed that workaholism was negatively related to age and positively related to the personality dimensions agreeableness, neuroticism, and intellect/imagination. Implications for these findings are discussed.

    The most recent study of the Wide Field Infrared Survey Telescope (WFIRST) mission is based on reuse of an existing 2.4m telescope. This study was commissioned by NASA to examine the potential science return and cost effectiveness of WFIRST by using this significantly larger aperture telescope. We review the science program envisioned by the WFIRST 2012-2013 Science Definition Team (SDT), an overview of the mission concept, and the telescope design and status. Comparisons against the previous 1.3m and reduced cost 1.1m WFIRST design concepts are discussed. A significant departure from past point designs is the option for serviceability and the geostationary orbit location which enables servicing and replacement instrument insertion later during mission life. Other papers at this conference provide more in depth discussion of the wide field instrument and the optional exoplanet imaging coronagraph instrument.

    Research indicates expectant and new mothers use the Internet, specifically social media, to gain information and support during the transition to parenthood. Although parents regularly share information about and photos of their child or children on Facebook, researchers have neither explored the use of Facebook to share pregnancy-related information nor investigated factors that influence such sharing. The aim of this study was to address a gap in the literature by exploring the use of Facebook by pregnant women. Specifically, the study examined the use of Facebook to share pregnancy-related information, as well as any association between prenatal attachment and the aforementioned aspects of sharing pregnancy-related information on Facebook. Pregnant women who were at least 18 years of age were recruited for participation in the study through posts and paid advertisements on Facebook and posts to professional organization listservs. Individuals interested in participating were directed to a secure Web-based survey system where they completed the consent form and the survey that focused on their current pregnancy. Participants completed the Maternal Antenatal Attachment Scale and answered questions that assessed how often they shared pregnancy-related information on Facebook, who they shared it with, why they shared it, and what they shared. A total of 117 pregnant women completed the survey. Descriptive statistics indicated that the pregnancy announcement was most commonly shared (75/108, 69.4%), with most women sharing pregnancy-related information on Facebook less than monthly (52/117, 44.4%) with only family and friends (90/116, 77.6% and 91/116, 78.4%, respectively) and for the purpose of involving others or sharing the experience (62/107, 57.9%). Correlation and regression analyses showed that prenatal attachment, in general, was positively and significantly related to all aspects of sharing pregnancy-related information at the PFacebook for a variety of

    Limited data are available regarding the undergraduate dermatology clinical clerkship curriculum in the United States. Our primaryaim is to assess medical students' perspectives of the dermatology clinical clerkship. A multicenter survey study was conducted, which included four California dermatology academic programs. A 17-item questionnaire was designed to investigate medical student perception with regard tothe overall educational value of the various teaching aspects of the dermatology clinical clerkship. A total of 152 medical student surveys were completed. Over half of the medical students felt proficient in diagnosing the most commondermatologic conditions. Eighty-seven percent of medical students were very satisfied with the dermatology clerkship. Ninety-one percent of students felt the length of the clerkship was appropriate. The vast majority of medical students reported a high level of proficiency in the treatment and diagnosis of common skin disorders. In contrast, our findings suggest that medical students may not begaining sufficient hands-on experience in conducting certain dermatologic procedures following the dermatology clerkship. Overall, medical studentperception of the dermatology clinical clerkship was mostly positive.

    Advanced hemodynamic monitoring is recommended in patients with complex circulatory shock. To evaluate the current attitudes and beliefs among German intensivists, regarding advanced hemodynamic monitoring, the actual hemodynamic management in clinical practice, and the barriers to using it. Web-based survey among members of the German Society of Medical Intensive Care and Emergency Medicine. Of 284 respondents, 249 (87%) agreed that further hemodynamic assessment is needed to determine the type of circulatory shock if no clear clinical diagnosis can be made. In all, 281 (99%) agreed that echocardiography is helpful for this purpose (transpulmonary thermodilution: 225 [79%]; pulmonary artery catheterization: 126 [45%]). More than 70% of respondents agreed that blood flow variables (cardiac output, stroke volume) should be measured in patients with hemodynamic instability. The parameters most respondents agreed should be assessed in a patient with hemodynamic instability were mean arterial pressure, cardiac output, and serum lactate. Echocardiography is available in 99% of ICUs (transpulmonary thermodilution: 91%; pulmonary artery catheter: 63%). The respondents stated that, in clinical practice, invasive arterial pressure measurements and serum lactate measurements are performed in more than 90% of patients with hemodynamic instability (cardiac output monitoring in about 50%; transpulmonary thermodilution in about 40%). The respondents did not feel strong barriers to the use of advanced hemodynamic monitoring in clinical practice. This survey study shows that German intensivists deem advanced hemodynamic assessment necessary for the differential diagnosis of circulatory shock and to guide therapy with fluids, vasopressors, and inotropes in ICU patients.

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.

    2014-05-01

    In this paper, we have selected a sample of massive star-forming regions from the Red MSX Source survey, in order to study star formation activities (mainly outflow and inflow signatures). We have focused on three molecular lines from the Millimeter Astronomy Legacy Team Survey at 90 GHz: HCO+(1-0), H13CO+(1-0) and SiO(2-1). According to previous observations, our sources can be divided into two groups: nine massive young stellar object candidates (radio-quiet) and 10 H II regions (which have spherical or unresolved radio emissions). Outflow activities have been found in 11 sources, while only three show inflow signatures in all. The high outflow detection rate means that outflows are common in massive star-forming regions. The inflow detection rate was relatively low. We suggest that this was because of the beam dilution of the telescope. All three inflow candidates have outflow(s). The outward radiation and thermal pressure from the central massive star(s) do not seem to be strong enough to halt accretion in G345.0034-00.2240. Our simple model of G318.9480-00.1969 shows that it has an infall velocity of about 1.8 km s-1. The spectral energy distribution analysis agrees our sources are massive and intermediate-massive star formation regions.

    Paramedics participate in continuing medical education (CME) to maintain their skills and knowledge. An understanding of learning styles is important for education to be effective. This study examined the preferred learning styles of ground ambulance paramedics and describes how their preferred learning styles relate to the elective CME activities these paramedics attend. All paramedics (n=1,036) employed in a provincial ground ambulance service were invited to participate in a survey containing three parts: demographics, learning style assessed by the Kolb Learning Style Inventory (LSI), and elective CME activity. 260 paramedics (25%) participated in the survey. Preferred learning styles were: assimilator, 28%; diverger, 25%; converger, 24%; and accommodator, 23%. Advanced life support (ALS) providers had a higher proportion of assimilators (36%), and basic life support (BLS) providers had a higher proportion of divergers (30%). The learning style categories of CME activities attended by paramedics were: assimilators, 25%; divergers, 26%; convergers, 25%; and accommodators, 24%. These results suggest that paramedics are a diverse group of learners, and learning style differs within their demographics. Paramedics attend CME activities that complement all learning styles. Organizations providing education opportunities to paramedics should consider paramedics a diverse learning group when designing their CME programs.

    This study aimed to assess radiologists' knowledge about breast density legislation as well as perceived practice changes resulting from the enactment of breast density legislation. This is an institutional review board-exempt anonymous email survey of 523 members of the New England Roentgen Ray Society. In addition to radiologist demographics, survey questions addressed radiologist knowledge of breast density legislation, knowledge of breast density as a risk factor for breast cancer, recommendations for supplemental screening, and perceived practice changes resulting from density notification legislation. Of the 523 members, 96 responded, yielding an 18% response rate. Seventy-three percent of respondents practiced in a state with breast density legislation. Sixty-nine percent felt that breast density notification increased patient anxiety about breast cancer, but also increased patient (74%) and provider (66%) understanding of the effect of breast density on mammographic sensitivity. Radiologist knowledge of the relative risk of breast cancer when comparing breasts of different density was variable. Considerable confusion and controversy regarding breast density persists, even among practicing radiologists. Copyright © 2017 The Association of University Radiologists. Published by Elsevier Inc.

    2012-01-01

    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. PMID:23102060

    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.

    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.

    Background Transmission of Streptococcus mutans from mother-to-child can lead to Early Childhood Caries. A previous study identified characteristics and beliefs of general dentists about counseling pregnant women to reduce risk of infection and Early Childhood Caries. This study extends those findings with an analysis of county level factors. Methods In 2006, we surveyed 732 general dentists in Oregon, USA about dental care for pregnant women. Survey items asked about individual and practice characteristics. In the present study we matched those data to county level factors and used multinomial logistic regression to test the effects of the factors (i.e., dentist to population ratio, percentage of female dentists, percentage of females of childbearing age, and percentage of individuals living in poverty) on counseling behavior. Results County level factors were unrelated to counseling behavior when the models controlled for dentists' individual attitudes, beliefs, and practice level characteristics. The adjusted odds ratios for no counseling of pregnant patients (versus 100 percent counseling) were 1.1 (95% CI .8-1.7), 1.0 (1.0-1.1), 1.2 (.9-1.5), and 1.1 (1.0-1.2) for dentist/population ratio, percent female dentists, percent females of childbearing age, and percent in poverty, respectively Similar results were obtained when dentists who counseled some patients were compared to those counseling 100 percent of patients. Conclusions Community level factors do not appear to impact the individual counseling behavior of general dentists in Oregon, USA regarding the risk of maternal transmission of Early Childhood Caries.

  20. An assessment of survey measures used across key epidemiologic studies of United States Gulf War I Era Veterans

    Science.gov (United States)

    2013-01-01

    Over the past two decades, 12 large epidemiologic studies and 2 registries have focused on U.S. veterans of the 1990–1991 Gulf War Era. We conducted a review of these studies’ research tools to identify existing gaps and overlaps of efforts to date, and to advance development of the next generation of Gulf War Era survey tools. Overall, we found that many of the studies used similar instruments. Questions regarding exposures were more similar across studies than other domains, while neurocognitive and psychological tools were the most variable. Many studies focused on self-reported survey results, with a range of validation practices. However, physical exams, biomedical assessments, and specimen storage were not common. This review suggests that while research may be able to pool data from past surveys, future surveys need to consider how their design can yield data comparable with previous surveys. Additionally, data that incorporate recent technologies in specimen and genetic analyses would greatly enhance such survey data. When combined with existing data on deployment-related exposures and post-deployment health conditions, longitudinal follow-up of existing studies within this collaborative framework could represent an important step toward improving the health of veterans.

    Achieving adequate response rates is an ongoing challenge for longitudinal studies. The World Trade Center Health Registry is a longitudinal health study that periodically surveys a cohort of ~71,000 people exposed to the 9/11 terrorist attacks in New York City. Since Wave 1, the Registry has conducted three follow-up surveys (Waves 2-4) every 3-4 years and utilized various strategies to increase survey participation. A promised monetary incentive was offered for the first time to survey non-respondents in the recent Wave 4 survey, conducted 13-14 years after 9/11. We evaluated the effectiveness of a monetary incentive in improving the response rate five months after survey launch, and assessed whether or not response completeness was compromised due to incentive use. The study compared the likelihood of returning a survey for those who received an incentive offer to those who did not, using logistic regression models. Among those who returned surveys, we also examined whether those receiving an incentive notification had higher rate of response completeness than those who did not, using negative binomial regression models and logistic regression models. We found that a $10 monetary incentive offer was effective in increasing Wave 4 response rates. Specifically, the $10 incentive offer was useful in encouraging initially reluctant participants to respond to the survey. The likelihood of returning a survey increased by 30% for those who received an incentive offer (AOR = 1.3, 95% CI: 1.1, 1.4), and the incentive increased the number of returned surveys by 18%. Moreover, our results did not reveal any significant differences on response completeness between those who received an incentive offer and those who did not. In the face of the growing challenge of maintaining a high response rate for the World Trade Center Health Registry follow-up surveys, this study showed the value of offering a monetary incentive as an additional refusal conversion strategy.

    Alcohol use is among the most important risk factors for burden of disease globally. An estimated quarter of the total alcohol consumed globally is unrecorded. However, due partly to the challenges associated with its assessment, evidence concerning the magnitude of unrecorded alcohol use is sparse. This study estimated country-specific proportions of unrecorded alcohol used in 2015. A statistical model was developed for data prediction using data on the country-specific proportion of unrecorded alcohol use from nominal group expert assessments and secondary, nationally representative survey data and country-level covariates. Estimates were calculated for the country level, for four income groups and globally. A total of 129 participants from 49 countries were included in the nominal group expert assessments. The survey data comprised 66 538 participants from 16 countries. Experts completed a standardized questionnaire assessing the country-specific proportion of unrecorded alcohol. In the national surveys, the number of standard drinks of total and unrecorded alcohol use was assessed for the past 7 days. Based on predictions for 167 countries, a population-weighted average of 27.9% [95% confidence interval (CI) = 10.4-44.9%] of the total alcohol consumed in 2015 was unrecorded. The proportion of unrecorded alcohol was lower in high (9.4%, 95% CI = 2.4-16.4%) and upper middle-income countries (18.3%, 95% CI = 9.0-27.6%) and higher in low (43.1%, 95% CI = 26.5-59.7%) and lower middle-income countries (54.4%, 95% CI = 38.1-70.8%). This corresponded to 0.9 (high-income), 1.2 (upper middle-income), 3.2 (lower middle-income) and 1.8 (low-income) litres of unrecorded alcohol per capita. A new method for modelling the country-level proportion of unrecorded alcohol use globally showed strong variation among geographical regions and income groups. Lower-income countries were associated with a higher proportion of unrecorded alcohol than higher-income countries

    This study aimed at examining predictors of healthy and unhealthy snacking at work. As proximal predictors we looked at food-choice motives (health motive, affect-regulation motive); as distal predictors we included organizational eating climate, emotional eating, and self-control demands at work. We collected daily survey data from 247 employees, over a period of 2 workweeks. Multilevel structural equation modeling showed that organizational eating climate predicted health as food-choice motive, whereas emotional eating and self-control demands predicted affect regulation as food-choice motive. The health motive, in turn, predicted consuming more fruits and more cereal bars and less sweet snacks; the affect-regulation motive predicted consuming more sweet snacks. Findings highlight the importance of a health-promoting eating climate within the organization and point to the potential harm of high self-control demands at work.

    Osteoarthritis (OA) is a chronic, degenerative disease that is highly prevalent in the population, yet the factors that affect purchasing decisions related to this condition are poorly understood. A questionnaire was developed and administered to hospital executives across North America to determine the factors that affect purchasing decisions related to OA. Thirty-four individuals participated in the survey. Clinical evidence and cost effectiveness were deemed to be the most important factors in the process of making purchasing decisions. The most important considerations for adopting new technology were whether there was sufficient evidence in the literature, followed by thoughts of key opinion leaders, and cost of intervention/device. Ongoing research is still needed, but the current study allowed us to identify some trends in the data, providing new insight on how hospital purchasing decisions are made, which could have an immediate impact on those currently involved with making these decisions.

    Full Text Available This paper discusses environmental complaints made by citizens living close to industrial polluters in China. Data collected from a questionnaire survey in Suzhou City is used for the analysis. The results confirm a marginal level of citizen environmental complaints in the study area at present. Meaningful findings include the fact that citizens have a tendency to complain collectively, and that perception of the level of environmental information provided by companies significantly determines a citizen’s likelihood of lodging environmental complaints. Therefore, the disclosure of corporate environmental information must be emphasized continuously; citizens must be encouraged to correctly understand the environmental performance of companies so that they might make appropriate complaints. Governments need to show their support for citizen-led environmental complaint initiatives. The successful cases would convince them to keep a closer eye on their neighbouring polluters.

Surveying the administrators of 121 graduate occupational therapy programs in the United States, we found that the majority of the respondents identified their program as using IT in some form for lecturebased courses, with less inclusion of IT for laboratory-based courses. Hybrid instruction, with the majority of the content being delivered face-to-face and the remainder via online, were the trends among the respondents. The findings also indicated that the respondents’ programs avoid certain IT, including synchronous online chat rooms or instant messaging, digital image collections, blogs or online journaling, Wikis, and audio/video podcasting. Few of the respondents said their programs had made a significant leap into implementing a larger online presence with instructional technology

    Feeding and swallowing impairments are key predictors of increased morbidity and mortality in adults with learning disabilities. This postal survey and interview study sought to identify risk factors in adults with learning disabilities who have histories of choking. A total of 2000 questionnaires were sent to carers of all adults with learning disabilities registered as service users by three local health authorities. (A 'service user' may be using any specialist learning disability health or social care facility with day, residential or therapeutic services). Of the 674 service users for whom surveys were returned, 47 were living in hospital, 396 were living in residential or group homes and 208 were living with relatives, or in their own homes. Eighteen subjects who had reported serious or repeated episodes of choking were interviewed in depth in their residences or workplaces. Responses were subjected to frequency analyses. Personal characteristics were analysed. Choking patterns were differentiated by food texture. A total of 34% of questionnaires on 674 service users were returned; 42% of respondents reported one or more choking episodes. There was a significantly greater occurrence of choking among people with more severe learning disability, with Down syndrome, people who had an incomplete dentition or were taking a greater number of psychotropic drugs. Antisocial eating habits learnt in institutional settings presented an additional choking hazard for some individuals. Choking is a serious hazard for many adults with learning disabilities. This study establishes many of the characteristics associated with swallowing problems in this population. Clinicians and carers should benefit from awareness of these predictors, leading to better management of eating behaviours and habits. A choking and swallowing risk assessment should be included in routine health assessments of adults with learning disability, paying especial attention to the condition of a person

    The high rate of home deliveries conducted by unskilled birth attendants in resource-limited settings is an important global health issue because it is believed to be a significant contributing factor to maternal and newborn mortality. Given the large number of deliveries that are managed by unskilled or traditional birth attendants outside of health facilities, and the fact that there is on-going discussion regarding the role of traditional birth attendants in the maternal newborn health (MNH) service continuum, we sought to ascertain the practices of traditional birth attendants in our catchment area. The findings of this descriptive study might help inform conversations regarding the roles that traditional birth attendants can play in maternal-newborn health care. A structured questionnaire was used in a survey that included one hundred unskilled birth attendants in western Kenya. Descriptive statistics were employed. Inappropriate or outdated practices were reported in relation to some obstetric complications and newborn care. Encouraging results were reported with regard to positive relationships that traditional birth attendants have with their local health facilities. Furthermore, high rates of referral to health facilities was reported for many common obstetric emergencies and similar rates for reporting of pregnancy outcomes to village elders and chiefs. Potentially harmful or outdated practices with regard to maternal and newborn care among traditional birth attendants in western Kenya were revealed by this study. There were high rates of traditional birth attendant referrals of pregnant mothers with obstetric complications to health facilities. Policy makers may consider re-educating and re-defining the roles and responsibilities of traditional birth attendants in maternal and neonatal health care based on the findings of this survey.

    Full Text Available The US Congress established the designation of Critical Access Hospitals in 1997, recognising rural hospitals as vital links to health for rural and underserved populations. The intent of the reimbursement system is to improve financial performance, thereby reducing hospital closures. Informatics applications are thought to be tools that can enable the sustainability of such facilities. The aim of this study is to identify the current use of information and communication technology in Critical Access Hospitals, and to assess their readiness and receptiveness for the use of new software and hardware applications and their perceived information technology (IT needs. A survey was mailed to the administrators of all Critical Access Hospitals in one US state (Missouri and a reminder was mailed a few weeks later. Twenty-seven out of 33 surveys were filled out and returned (response rate 82%. While most respondents (66.7% stated that their employees have been somewhat comfortable in using new technology, almost 15% stated that their employees have been somewhat uncomfortable. Similarly, almost 12% of the respondents stated that they themselves felt somewhat uncomfortable introducing new technology. While all facilities have computers, only half of them have a specific IT plan. Findings indicate that Critical Access Hospitals are often struggling with lack of resources and specific applications that address their needs. However, it is widely recognised that IT plays an essential role in the sustainability of their organisations. The study demonstrates that IT applications have to be customised to address the needs and infrastructure of the rural settings in order to be accepted and properly utilised.

    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. © the American Music Therapy Association 2017.

    There is compelling evidence for the benefits of regular exercise during pregnancy, and medical practitioners (MPs) can play an important role in changing antenatal health behaviours. The purpose of this study was to assess the knowledge, attitudes and beliefs of South African MPs towards exercise during pregnancy. A convenience sample of ninety-six MPs working in the private health care sector, including General Practitioners (n = 58), Obstetricians/Gynaecologists (n = 33) and other Specialists (n = 5), participated in this cross sectional, descriptive survey study. A 33-item questionnaire was distributed manually at medical practices and via email to an on-line survey tool. Descriptive statistics and frequency tables were calculated for all questions. Chi-squared and Fisher's exact statistical tests were used to determine the differences in response by age, speciality and years of practice (p exercise during pregnancy is beneficial, and were knowledgeable on most of the expected benefits. Seventy-eight percent believed that providing exercise advice is an important part of prenatal care, however only 19% provided informational pamphlets and few (24%) referred to exercise specialists. A large majority (83%) were unaware of the recommended exercise guidelines. Although age and years of practice played no role in this awareness, practitioners who focussed on obstetrics and gynaecology were more likely to be aware of the current guidelines, than those in general practice (p exercise during pregnancy, their advice did not always align with the current guidelines. Therefore, better dissemination of available research is warranted, to bridge the gap between clinical knowledge and current recommendations for physical activity promotion.

    Though Ayurveda is practiced in the Indian subcontinent since centuries, there is a paucity of systematic documentation related to the occurrence of adverse drug reactions (ADR) and other issues regarding the safety of Ayurveda medicines. To monitor and analyze the pattern and frequency of ADR to Ayurvedic medicines in an Ayurvedic hospital setup. In this prospective study, ADR monitoring was done in KLE Ayurveda Secondary Care Hospital, Belgaum, Karnataka, India by spontaneous and intensive monitoring technique for a span of 1-year (June 2010 to May 2011). Data pertaining to patient demography, drug and reaction characteristics, organ system involved and reaction outcomes were collected and evaluated. The reaction severity and predisposing factors were also assessed. In a span of one year, 84 adverse drug events were reported out of which 52 confirmed as ADR. The overall incidence of ADR in the patient population was 1.14%, out of which 23 (44.23%) were related to Panchakarma (detoxification process), 13 (25.00%) related to the herbal formulations and 06 (11.53%) were of Rasa Aushadhi (mineral or herbo-mineral formulations). The commonly affected organ systems were gastrointestinal system 24 (46.15%) and skin 15 (28.84%). The majority of the reactions were moderate 30 (57.69%) to mild 20 (38.46%) in severity. Most patients recovered from the incidence. The present work has documented the incidence and characteristic of ADR to Ayurvedic medicine in a typical Ayurveda hospital setup. This will help in developing various strategies for boosting pharmacovigilance in Ayurveda, thereby ensuring safer use of Ayurveda medicines.

    Amphibian populations are known, or thought to be, declining worldwide. Although protected natural areas may act as reservoirs of biological integrity and serve as benchmarks for comparison with unprotected areas, they are not immune from population declines and extinctions and should be monitored. Unfortunately, identifying survey sites and performing long-term fieldwork within such (often remote) areas involves a special set of problems. We used the USDA Natural Resource Conservation Service Soil Survey Geographic (SSURGO) Database to identify, a priori, potential habitat for aquatic-breeding amphibians on North and South Manitou Islands, Sleeping Bear Dunes National Lakeshore, Michigan, and compared the results to those obtained using National Wetland Inventory (NWI) data. The SSURGO approach identified more target sites for surveys than the NWI approach, and it identified more small and ephemeral wetlands. Field surveys used a combination of daytime call surveys, night-time call surveys, and perimeter surveys. We found that sites that would not have been identified with NWI data often contained amphibians and, in one case, contained wetland-breeding species that would not have been found using NWI data. Our technique allows for easy a priori identification of numerous survey sites that might not be identified using other sources of spatial information. We recognize, however, that the most effective site identification and survey techniques will likely use a combination of methods in addition to those described here.

    In this paper, we present a study of quasar selection using the supernova fields of the Dark Energy Survey (DES). We used a quasar catalog from an overlapping portion of the SDSS Stripe 82 region to quantify the completeness and efficiency of selection methods involving color, probabilistic modeling, variability, and combinations of color/probabilistic modeling with variability. In all cases, we considered only objects that appear as point sources in the DES images. We examine color selection methods based on the Wide-field Infrared Survey Explorer (WISE) mid-IR W1-W2 color, a mixture of WISE and DES colors (g - i and i-W1), and a mixture of Vista Hemisphere Survey and DES colors (g - i and i - K). For probabilistic quasar selection, we used XDQSO, an algorithm that employs an empirical multi-wavelength flux model of quasars to assign quasar probabilities. Our variability selection uses the multi-band χ"2-probability that sources are constant in the DES Year 1 griz-band light curves. The completeness and efficiency are calculated relative to an underlying sample of point sources that are detected in the required selection bands and pass our data quality and photometric error cuts. We conduct our analyses at two magnitude limits, i 85% for both i-band magnitude limits and efficiencies of >80% to the bright limit and >60% to the faint limit; however, the giW1 and giW1+variability methods give the highest quasar surface densities. The XDQSOz method and combinations of W1W2/giW1/XDQSOz with variability are among the better selection methods when both high completeness and high efficiency are desired. We also present the OzDES Quasar Catalog of 1263 spectroscopically confirmed quasars from three years of OzDES observation in the 30 deg"2 of the DES supernova fields. Finally, the catalog includes quasars with redshifts up to z ~ 4 and brighter than i = 22 mag, although the catalog is not complete up to this magnitude limit.

    Medical photography enhances patient care, medical education and research. Despite medical photography's widespread use, little is known about how dermatologists choose to implement photography in routine clinical practice, and how they approach issues of image storage, image security and patient consent. To characterize dermatologists' medical photography habits and opinions. A 32-item anonymous, multiple-choice SurveyMonkey questionnaire about medical photography practices was emailed to programme directors of the 117 United States (US) dermatology residency programmes between May and August 2015, with a request to forward to faculty and affiliated dermatologists. Only board-certified dermatologists practicing in the United States were eligible. The Institutional Review Board exempted our study from full review. Our survey included 153 board-certified dermatologists, primarily representing the north-east (43.1%) and identifying as academic dermatologists (75.5%). Medical photography is prevalent: 61.8% report everyday use and 21.7% photograph every patient. Those reporting rare use (3.3%) were, on average, 20 years older. Dermatologists most commonly use photography to mark biopsy sites (87.5%), track disease (82.9%) and for education/teaching (72.4%). Nearly half (46%) use smartphone cameras. Emailing and texting photographs with patients or colleagues are common (69.1%). Most dermatologists (75.7%) always request patient consent for photographs. Only 23.7% adhere to a photography protocol and 73.9% desire more training opportunities. Dermatologists value medical photography. While patterns of image acquisition, storage and consent are noted, a variety of methods and preferences exist. Clearer photography guidelines and increased educational resources are likely to improve image quality, exchangeability and confidentiality. © 2018 European Academy of Dermatology and Venereology.

    Full Text Available Abstract Background An estimated one-half of Americans have limited health literacy skills. Low literacy has been associated with less receipt of preventive services, but its impact on colorectal cancer (CRC screening is unclear. We sought to determine whether low literacy affects patients' knowledge or receipt of CRC screening. Methods Pilot survey study of patients aged 50 years and older at a large, university-affiliated internal medicine practice. We assessed patients' knowledge and receipt of CRC screening, basic sociodemographic information, and health literacy level. We defined limited literacy as reading below the ninth grade level as determined by the Rapid Estimate of Adult Literacy in Medicine. Bivariate analyses and exact logistic regression were used to determine the association of limited health literacy with knowledge and receipt of CRC screening. Results We approached 105 patients to yield our target sample of 50 completing the survey (recruitment rate 48%. Most subjects were female (72%, African-American (58%, and had household incomes less than $25,000 (87%. Overall, 48% of patients had limited literacy skills (95% CI 35% to 61%. Limited literacy patients were less likely than adequate literacy patients to be able to name or describe any CRC screening test (50% vs. 96%, p Conclusion Patients with limited literacy skills are less likely to be knowledgeable of CRC screening compared to adequate literacy patients. Primary care providers should ensure patients' understanding of CRC screening when discussing screening options. Further research is needed to determine if educating low literacy patients about CRC screening can increase screening rates.

    OBJECTIVE : The purpose of this study was to elicit feedback from simulation technicians prior to developing the first simulation technician-specific simulation laboratory in Akron, OH. Simulation technicians serve a vital role in simulation centers within hospitals/health centers around the world. The first simulation technician degree program in the US has been approved in Akron, OH. To satisfy the requirements of this program and to meet the needs of this special audience of learners, a customized simulation lab is essential. A web-based survey was circulated to simulation technicians prior to completion of the lab for the new program. The survey consisted of questions aimed at identifying structural and functional design elements of a novel simulation center for the training of simulation technicians. Quantitative methods were utilized to analyze data. Over 90% of technicians (n=65) think that a lab designed explicitly for the training of technicians is novel and beneficial. Approximately 75% of respondents think that the space provided appropriate audiovisual (AV) infrastructure and space to evaluate the ability of technicians to be independent. The respondents think that the lab needed more storage space, visualization space for a large number of students, and more space in the technical/repair area. CONCLUSIONS : A space designed for the training of simulation technicians was considered to be beneficial. This laboratory requires distinct space for technical repair, adequate bench space for the maintenance and repair of simulators, an appropriate AV infrastructure, and space to evaluate the ability of technicians to be independent.

    The world's population is aging, and the need for nurses is increasing. Working with older adults, however, has always been an unpopular career choice among student nurses. It is important to understand student nurses' motivation for choosing gerontological nursing as a career. The purpose of this study was to examine the motivation for choosing gerontological nursing as a career and to identify the associated factors among student nurses. Cross-sectional survey. Participants were last-semester student nurses from 7 universities offering nursing undergraduate programs in Shandong, China. Of the 1290 student nurses, 916 completed the survey (a response rate of 71.0%). The outcome variable was the motivation to choose gerontological nursing as a career. This was measured using a motivation questionnaire that included expectancy and value subscales. Other instruments included the Chinese version of the Facts on Aging Quiz I, the Geriatrics Attitudes Scale, the Anxiety about Aging Scale, a clinical practice environment questionnaire and a self-administered general information questionnaire. Student nurses' expectancy and value aspects of motivation for choosing gerontological nursing as a career were both at a moderate level; the highest value they held was of personal interest. Clinical practice environment, anxiety about aging and the attitudes about geriatrics were the main factors influencing student nurses' motivation to choose gerontological nursing as a career in China. It is imperative for nurse educators to improve the gerontological nursing clinical practice environment for student nurses. Moreover, cultivating student nurses' positive attitudes about geriatrics and relieving anxiety about aging could be beneficial. Copyright © 2015. Published by Elsevier Ltd.

    Full Text Available The extension of universal health service insurance to national populations is a relatively new phenomenon. Since 1995, the Israeli National Health Insurance Law (NHIL has provided universal health services to every resident, but the effect of this law on health and health services among minorities has not been examined sufficiently. The goals of this study were to track some of the first changes engendered by the NHIL among the Negev Bedouin Arabs to examine the effects of universal health care services. Methods included analysis of historical and health policy documents, three field appraisals of health care services (1994, 1995, 1999, a region-wide interview survey of Negev Bedouins (1997, and key informant interviews. For the interview survey, a sample of 515 households was chosen from different Bedouin localities representing major sedentarization stages. Results showed that prior to the NHIL, a substantial proportion of the Negev Bedouins were uninsured with limited, locally available health service. Since 1995, health services, particularly primary care clinics and health manpower, have dramatically expanded. The initial expansion appears to have been a marketing ploy, but real improvements have occurred. There was a high level of health service utilization among the Bedouins in the Negev, especially private medical services, hospitals, and night ambulatory medical services. The NHIL brought change to the structure of health services in Israel, namely the institution of a national health system based on proportional allocation of resources (based on size and age and open competition in the provision of quality health care. The expansion of the pool of potential members engendered by the new universal coverage had profound effects on the Health Funds' attitudes towards Negev Bedouins. In addition, real consumer choice was introduced for the first time. Although all the health care needs of this rapidly growing population have yet to be met

    Demands for constellation satellites were surveyed and satellite systems were studied for extracting basic technical tasks relative to constellation satellite systems and for drafting space verification plans. For a constellation satellite system to accomplish its missions, two or more satellites have to be simultaneously navigated. It is assumed that its field of application will cover earth observation, information communication, risk management, disaster prevention, and the like. With such applications taken into consideration, surveys and studies were conducted about the need and marketability of constellation satellites, need of state-level involvement, and requests for missions to be imposed on a constellation system. For plural satellites to satisfy mission requests by coordinating with each other, it will be necessary to develop basic technologies, such as navigational guidance, communications control, system autonomous management, and operation on the ground. Functions and performance that a constellation satellite system are requested to have and basic technologies to be studied and developed were extracted, and space verification plans were drafted.

    Background The implementation of an Internet option in an existing public health interview survey using a mixed-mode design is attractive because of lower costs and faster data availability. Additionally, mixed-mode surveys can increase response rates and improve sample composition. However, mixed-mode designs can increase the risk of measurement error (mode effects). Objective This study aimed to determine whether the prevalence rates or mean values of self- and parent-reported health indicators for children and adolescents aged 0-17 years differ between self-administered paper-based questionnaires (SAQ-paper) and self-administered Web-based questionnaires (SAQ-Web), as well as between a single-mode control group and different mixed-mode groups. Methods Data were collected for a methodological pilot of the third wave of the "German Health Interview and Examination Survey for Children and Adolescents". Questionnaires were completed by parents or adolescents. A population-based sample of 11,140 children and adolescents aged 0-17 years was randomly allocated to 4 survey designs—a single-mode control group with paper-and-pencil questionnaires only (n=970 parents, n=343 adolescents)—and 3 mixed-mode designs, all of which offered Web-based questionnaire options. In the concurrent mixed-mode design, both questionnaires were offered at the same time (n=946 parents, n=290 adolescents); in the sequential mixed-mode design, the SAQ-Web was sent first, followed by the paper questionnaire along with a reminder (n=854 parents, n=269 adolescents); and in the preselect mixed-mode design, both options were offered and the respondents were asked to request the desired type of questionnaire (n=698 parents, n=292 adolescents). In total, 3468 questionnaires of parents of children aged 0-17 years (SAQ-Web: n=708; SAQ-paper: n=2760) and 1194 questionnaires of adolescents aged 11-17 years (SAQ-Web: n=299; SAQ-paper: n=895) were analyzed.

    Science.gov (United States)

    2018-01-01

    Background Research indicates expectant and new mothers use the Internet, specifically social media, to gain information and support during the transition to parenthood. Although parents regularly share information about and photos of their child or children on Facebook, researchers have neither explored the use of Facebook to share pregnancy-related information nor investigated factors that influence such sharing. Objective The aim of this study was to address a gap in the literature by exploring the use of Facebook by pregnant women. Specifically, the study examined the use of Facebook to share pregnancy-related information, as well as any association between prenatal attachment and the aforementioned aspects of sharing pregnancy-related information on Facebook. Methods Pregnant women who were at least 18 years of age were recruited for participation in the study through posts and paid advertisements on Facebook and posts to professional organization listservs. Individuals interested in participating were directed to a secure Web-based survey system where they completed the consent form and the survey that focused on their current pregnancy. Participants completed the Maternal Antenatal Attachment Scale and answered questions that assessed how often they shared pregnancy-related information on Facebook, who they shared it with, why they shared it, and what they shared. Results A total of 117 pregnant women completed the survey. Descriptive statistics indicated that the pregnancy announcement was most commonly shared (75/108, 69.4%), with most women sharing pregnancy-related information on Facebook less than monthly (52/117, 44.4%) with only family and friends (90/116, 77.6% and 91/116, 78.4%, respectively) and for the purpose of involving others or sharing the experience (62/107, 57.9%). Correlation and regression analyses showed that prenatal attachment, in general, was positively and significantly related to all aspects of sharing pregnancy-related information

    1975-01-01

    Much of the social science literature on environment is of recent origin and represents the response of the social science research community to a complex societal problem in which technology is a major factor. Energy represents another such problem to which the social science research community is now turning its attention. Because energy problems and environment problems have some similarities and because energy-conversion processes have large effects on the environment, a review of the social science literature on environment was undertaken. The purposes of this review are as follows: (1) to study the possible utility in energy research of some of the concepts developed in social science research on the environment; (2) to study the possible utility in energy research of some of the methodologies utilized in social science research on the environment; and (3) to study the extent to which the results of social science research on the environment have contributed to the development of policy. The first two items above receive major attention in this preliminary literature survey. 50 references.

    Adherence to the thinness model, self-acceptance such as self-esteem is psychological dynamics influencing the young age and emerging adulthood of women life. The purpose of this study was to investigate the girls and young women' ability to deal with the adherence to thinness model according to their self-body management thought daily self-perception of ownhabits and aptitude. We analysed their emotional patterns and body management to elucidate the Italian phenomenon. A cross-sectional study was conducted on 2287 Italian female distribute in range age 15-25 years old and distributed in girl and young women groups. We conducted a Survey study by snowball sampling technique. Our results showed that girls had higher emotional pattern scores when their weight and shape fit the thinness model: skinny girls felt positively about their body even if when they did not take adequate care of it. Italian girls consider the underweight body mass index an adherence model. Findings suggest the urgent need to plan prevention programme to model healthy behaviours about their daily good practice overcoming social and cultural models based on appearance.

    1996-01-01

    According to the data developed for the Proposed Site Treatment Plans, the US Department of Energy (DOE) mixed low-level and mixed transuranic waste inventory was estimated at 230,000 m 3 and embodied in approximately 2,000 waste streams. Many of these streams are unique and may require new technologies to facilitate compliance with Resource Conservation and Recovery Act disposal requirements. Because most waste streams are unique, a demonstration of the selected technologies is justified. Evaluation of commercially available or innovative technologies in a treatability study is a cost-effective method of providing a demonstration of the technology and supporting decisions on technology selection. This paper summarizes a document being prepared by the Mixed Waste Focus Area of the DOE Office of Science and Technology (EM-50). The document will provide DOE waste managers with a list of commercial firms (and universities) that have mixed-waste treatability study capabilities and with the specifics regarding the technologies available at those facilities. In addition, the document will provide a short summary of key points of the relevant regulations affecting treatability studies and will compile recommendations for successfully conducting an off-site treatability study. Interim results of the supplier survey are tabulated in this paper. The tabulation demonstrates that treatment technologies in 17 of the US Environmental Protection Agency's technology categories are available at commercial facilities. These technologies include straightforward application of standard technologies, such as pyrolysis, as well as proprietary technologies developed specifically for mixed waste. The paper also discusses the key points of the management of commercial mixed-waste treatability studies

  1. Developing optimal search strategies for detecting clinically sound prognostic studies in MEDLINE: an analytic survey

    Directory of Open Access Journals (Sweden)

    Haynes R Brian

    2004-06-01

    Full Text Available Abstract Background Clinical end users of MEDLINE have a difficult time retrieving articles that are both scientifically sound and directly relevant to clinical practice. Search filters have been developed to assist end users in increasing the success of their searches. Many filters have been developed for the literature on therapy and reviews but little has been done in the area of prognosis. The objective of this study is to determine how well various methodologic textwords, Medical Subject Headings, and their Boolean combinations retrieve methodologically sound literature on the prognosis of health disorders in MEDLINE. Methods An analytic survey was conducted, comparing hand searches of journals with retrievals from MEDLINE for candidate search terms and combinations. Six research assistants read all issues of 161 journals for the publishing year 2000. All articles were rated using purpose and quality indicators and categorized into clinically relevant original studies, review articles, general papers, or case reports. The original and review articles were then categorized as 'pass' or 'fail' for methodologic rigor in the areas of prognosis and other clinical topics. Candidate search strategies were developed for prognosis and run in MEDLINE – the retrievals being compared with the hand search data. The sensitivity, specificity, precision, and accuracy of the search strategies were calculated. Results 12% of studies classified as prognosis met basic criteria for scientific merit for testing clinical applications. Combinations of terms reached peak sensitivities of 90%. Compared with the best single term, multiple terms increased sensitivity for sound studies by 25.2% (absolute increase, and increased specificity, but by a much smaller amount (1.1% when sensitivity was maximized. Combining terms to optimize both sensitivity and specificity achieved sensitivities and specificities of approximately 83% for each. Conclusion Empirically derived

    1993-01-01

    This collection of 19 papers continues the annual series of U.S. Geological Survey reports on the geology of Alaska. The contributions, which include full-length Articles and shorter Geologic Notes, cover a broad range of topics including dune formation, stratigraphy, paleontology, isotopic dating, mineral resources, and tectonics. Articles, grouped under four regional headings, span nearly the entire State from the North Slope to southwestern, south-central, and southeastern Alaska (fig. 1).In the section on northern Alaska, Galloway and Carter use new data on dune morphology and radiocarbon ages from the western Arctic Coastal Plain to develop a late Holocene chronology of multiple episodes of dune stabilization and reactivation for the region. Their study has important implications for climatic changes in northern Alaska during the past 4,000 years. In two papers, Dumoulin and her coauthors describe lithofacies and conodont faunas of Carboniferous strata in the western Brooks Range, discuss depositional environments, and propose possible correlations and source areas for some of the strata.

    Dental schools have addressed full-time faculty shortages by utilizing part-time faculty and postdoctoral students as teachers. Studies have also shown that peer tutors in dental schools can be used effectively in addition to or in place of faculty, but there has been little research on whether the peer tutoring experience influences tutors to pursue academic careers. This study surveyed junior faculty at 60 U.S. dental schools about their predoctoral tutoring and teaching experiences. Data from 122 respondents were analyzed. The results indicated that more recent graduates had more peer tutoring opportunities available than those who graduated prior to the 1980s and that the teaching experiences influenced the respondents' decisions to pursue academic careers. Additionally, those peer tutoring programs that placed more responsibility on the peer tutors, signifying trust from the institution, were the most successful in influencing respondents' decisions to pursue academia. Finally, when comparing their predoctoral teaching experiences to faculty development of teaching skills at their current institutions, the majority of the respondents reported that the faculty development was better. However, the peer tutoring programs considered equal to or better than faculty development were more influential in stimulating participants' academic career interest. These results suggest that dental schools can look to peer tutoring and teaching programs to stimulate students' interest in academia that can help reduce faculty shortages in the long term, but only if programs are developed that place greater responsibility and trust in students and that equal the quality of faculty development programs.

    Full Text Available One of the primary issues on many developing countries is educational failure associated with schoolchildren or university students. Many students cannot continue their educations for different reasons such as lack of family support either financially or emotionally. In this paper, we study the effects of family background characteristics on educational participation in one of Iranian cities. We select 40 students who have the history of educational failure and distribute some questionnaire among them. Our survey is mainly based on relationship between family characteristics such as age, educational level, etc. The results indicate that different family characteristics could highly influence educational failure. Some of the most important factors that all students agreed on are family dispute, lack of interest and support on behalf of their parents, disregarding students' creativity, university professors with weak performance and high living expenses as well as high tuitions. There are other issues, which could impact educational failure such as having a university with good discipline and studying in overcrowded classes.

    Acute and enduring adverse effects of psilocybin have been reported anecdotally, but have not been well characterized. For this study, 1993 individuals (mean age 30 yrs; 78% male) completed an online survey about their single most psychologically difficult or challenging experience (worst "bad trip") after consuming psilocybin mushrooms. Thirty-nine percent rated it among the top five most challenging experiences of his/her lifetime. Eleven percent put self or others at risk of physical harm; factors increasing the likelihood of risk included estimated dose, duration and difficulty of the experience, and absence of physical comfort and social support. Of the respondents, 2.6% behaved in a physically aggressive or violent manner and 2.7% received medical help. Of those whose experience occurred >1 year before, 7.6% sought treatment for enduring psychological symptoms. Three cases appeared associated with onset of enduring psychotic symptoms and three cases with attempted suicide. Multiple regression analysis showed degree of difficulty was positively associated, and duration was negatively associated, with enduring increases in well-being. Difficulty of experience was positively associated with dose. Despite difficulties, 84% endorsed benefiting from the experience. The incidence of risky behavior or enduring psychological distress is extremely low when psilocybin is given in laboratory studies to screened, prepared, and supported participants. © The Author(s) 2016.

    Full Text Available Abstract Background This project is part of the Translating Research in Elder Care (TREC program of research, a multi-level and longitudinal research program being conducted in 36 nursing homes in three Canadian Prairie Provinces. The overall goal of TREC is to improve the quality of care for older persons living in nursing homes and the quality of work life for care providers. The purpose of this paper is to report on development and evaluation of facility annual reports (FARs from facility administrators’ perspectives on the usefulness, meaningfulness, and understandability of selected data from the TREC survey. Methods A cross sectional survey design was used in this study. The feedback reports were developed in collaboration with participating facility administrators. FARs presented results in four contextual areas: workplace culture, feedback processes, job satisfaction, and staff burnout. Six weeks after FARs were mailed to each administrator, we conducted structured telephone interviews with administrators to elicit their evaluation of the FARs. Administrators were also asked if they had taken any actions as a result of the FAR. Descriptive and inferential statistics, as well as content analysis for open-ended questions, were used to summarize findings. Results Thirty-one facility administrators (representing thirty-two facilities participated in the interviews. Six administrators had taken action and 18 were planning on taking action as a result of FARs. The majority found the four contextual areas addressed in FAR to be useful, meaningful, and understandable. They liked the comparisons made between data from years one and two and between their facility and other TREC study sites in their province. Twenty-two indicated that they would like to receive information on additional areas such as aggressive behaviours of residents and information sharing. Twenty-four administrators indicated that FARs contained enough information, while eight

    The implementation of an Internet option in an existing public health interview survey using a mixed-mode design is attractive because of lower costs and faster data availability. Additionally, mixed-mode surveys can increase response rates and improve sample composition. However, mixed-mode designs can increase the risk of measurement error (mode effects). This study aimed to determine whether the prevalence rates or mean values of self- and parent-reported health indicators for children and adolescents aged 0-17 years differ between self-administered paper-based questionnaires (SAQ-paper) and self-administered Web-based questionnaires (SAQ-Web), as well as between a single-mode control group and different mixed-mode groups. Data were collected for a methodological pilot of the third wave of the "German Health Interview and Examination Survey for Children and Adolescents". Questionnaires were completed by parents or adolescents. A population-based sample of 11,140 children and adolescents aged 0-17 years was randomly allocated to 4 survey designs-a single-mode control group with paper-and-pencil questionnaires only (n=970 parents, n=343 adolescents)-and 3 mixed-mode designs, all of which offered Web-based questionnaire options. In the concurrent mixed-mode design, both questionnaires were offered at the same time (n=946 parents, n=290 adolescents); in the sequential mixed-mode design, the SAQ-Web was sent first, followed by the paper questionnaire along with a reminder (n=854 parents, n=269 adolescents); and in the preselect mixed-mode design, both options were offered and the respondents were asked to request the desired type of questionnaire (n=698 parents, n=292 adolescents). In total, 3468 questionnaires of parents of children aged 0-17 years (SAQ-Web: n=708; SAQ-paper: n=2760) and 1194 questionnaires of adolescents aged 11-17 years (SAQ-Web: n=299; SAQ-paper: n=895) were analyzed.

    In 3D survey the aspects most discussed in the scientific community are those related to the acquisition of data from integrated survey (laser scanner, photogrammetric, topographic and traditional direct), rather than those relating to the interpretation of the data. Yet in the methods of traditional representation, the data interpretation, such as that of the philological reconstruction, constitutes the most important aspect. It is therefore essential in modern systems of survey and representation, filter the information acquired. In the system, based on the integrated survey that we have adopted, the 3D object, characterized by a cloud of georeferenced points, defined but their color values, defines the core of the elaboration. It allows to carry out targeted analysis, using section planes as a tool of selection and filtering data, comparable with those of traditional drawings. In the case study of the Abbey of Casamari (Veroli), one of the most important Cistercian Settlement in Italy, the survey made for an Agreement with the Ministry of Cultural Heritage and Activities and Tourism (MiBACT) and University of RomaTre, within the project "Accessment of the sismic safety of the state museum", the reference 3D model, consisting of the superposition and geo-references data from various surveys, is the tool with which yo develop representative models comparable to traditional ones. It provides the necessary spatial environment for drawing up plans and sections with a definition such as to develop thematic analysis related to phases of construction, state of deterioration and structural features.

  13. A method of encountering the ratio of adjacent sides and its applied study in nuclear engineering survey

    The cross side or range net survey method is to compute the average error of the measured lengths of sides. With the increment of the side length, the viewing variance increases greatly. Generally the photo-electrical distance survey equipment has a high inside precision, but it is affected by typical weather error so that the outside precision is decreased, and this weather error similar to systematic error greatly decreases the viewing side precision. To solve this problem, theoretical study and field test were carried out for the correlation of ratios among short sides by photo-electrical survey, and the stability degree of the ratios of sides, a new method of ratio encountering of adjacent sides is put forward. Because of the weights of the ration variance σ γ 2 = 2η 2 γ 2 and the angular variance σ β 2 = 2J 2 ρ 2 match each other, so the systematic error can be eliminated completely, and a survey point co-ordinate of high precision can be obtained. It is easy to operate, as it does not require multi-photo-band survey or to operate at the optimal observation time, and is especially suitable to nuclear engineering survey applications. (3 tabs.)

    The intended meaning behind responses to standard questions posed in large-scale health surveys are not always well understood. Systematic follow-up studies, particularly those which pose a few repeated questions followed by open-ended discussions, are well positioned to gauge stability and consistency of data and to shed light on the intended meaning behind survey responses. Such follow-up studies require extensive coordination and face challenges in protecting respondent confidentiality during the process of recontacting and reinterviewing participants. We describe practical field strategies for undertaking a mixed methods follow-up study during a large-scale health survey. The study was designed as a mixed methods follow-up study embedded within the 2014 Ghana Demographic and Health Survey (GDHS). The study was implemented in 13 clusters. Android tablets were used to import reference data from the parent survey and to administer the questionnaire, which asked a mixture of closed- and open-ended questions on reproductive intentions, decision-making, and family planning. Despite a number of obstacles related to recontacting respondents and concern about respondent fatigue, over 92 percent of the selected sub-sample were successfully recontacted and reinterviewed; all consented to audio recording. A confidential linkage between GDHS data, follow-up tablet data, and audio transcripts was successfully created for the purpose of analysis. We summarize the challenges in follow-up study design, including ethical considerations, sample size, auditing, filtering, successful use of tablets, and share lessons learned for future such follow-up surveys.

    Full Text Available This simulation study was prompted by the current increased interest in linking national studies to international large-scale assessments (ILSAs such as IEA's TIMSS, IEA's PIRLS, and OECD's PISA. Linkage in this scenario is achieved by including items from the international assessments in the national assessments on the premise that the average achievement scores from the latter can be linked to the international metric. In addition to raising issues associated with different testing conditions, administrative procedures, and the like, this approach also poses psychometric challenges. This paper endeavors to shed some light on the effects that can be expected, the linkage errors in particular, by countries using this practice. The ILSA selected for this simulation study was IEA TIMSS 2011, and the three countries used as the national assessment cases were Botswana, Honduras, and Tunisia, all of which participated in TIMSS 2011. The items selected as items common to the simulated national tests and the international test came from the Grade 4 TIMSS 2011 mathematics items that IEA released into the public domain after completion of this assessment. The findings of the current study show that linkage errors seemed to achieve acceptable levels if 30 or more items were used for the linkage, although the errors were still significantly higher compared to the TIMSS' cutoffs. Comparison of the estimated country averages based on the simulated national surveys and the averages based on the international TIMSS assessment revealed only one instance across the three countries of the estimates approaching parity. Also, the percentages of students in these countries who actually reached the defined benchmarks on the TIMSS achievement scale differed significantly from the results based on TIMSS and the results for the simulated national assessments. As a conclusion, we advise against using groups of released items from international assessments in national

    Evidence -based medicine (EBM) is designed to inform clinical decision-making within all medical specialties, including orthopaedic surgery. We recently published a pilot survey of the Canadian Orthopaedic Association (COA) membership and demonstrated that the adoption of EBM principles is variable among Canadian orthopaedic surgeons. The objective of this study was to conduct a broader international survey of orthopaedic surgeons to identify characteristics of research studies perceived as being most influential in informing clinical decision-making. A 29-question electronic survey was distributed to the readership of an established orthopaedic journal with international readership. The survey aimed to analyse the influence of both extrinsic (journal quality, investigator profiles, etc.) and intrinsic characteristics (study design, sample size, etc.) of research studies in relation to their influence on practice patterns. A total of 353 surgeons completed the survey. Surgeons achieved consensus on the 'importance' of three key designs on their practices: randomised controlled trials (94%), meta-analyses (75%) and systematic reviews (66%). The vast majority of respondents support the use of current evidence over historical clinical training; however subjective factors such as journal reputation (72%) and investigator profile (68%) continue to influence clinical decision-making strongly. Although intrinsic factors such as study design and sample size have some influence on clinical decision-making, surgeon respondents are equally influenced by extrinsic factors such as investigator reputation and perceived journal quality.Cite this article: Dr M.

    The prevalence of tobacco smoking in Germany is high (~27%). Monitoring of national patterns of smoking behaviour and data on the "real-world" effectiveness of cessation methods are needed to inform policies and develop campaigns aimed at reducing tobacco-related harm. In England, the Smoking Toolkit Study (STS) has been tracking such indicators since 2006, resulting in the adaptation of tobacco control policies. However, findings cannot be directly transferred into the German health policy context. The German Study on Tobacco Use (DEBRA: "Deutsche Befragung zum Rauchverhalten") aims to provide such nationally representative data. In June 2016, the study started collecting data from computer-assisted, face-to-face household interviews in people aged 14 years and older. Over a period of 3 years, a total of ~36,000 respondents will complete the survey with a new sample of ~2000 respondents every 2 months (=18 waves). This sample will report data on demographics and the use of tobacco and electronic (e-)cigarettes. Per wave, about 500-600 people are expected to be current or recent ex-smokers (German Clinical Trials Register ( DRKS00011322 ) on 25th November 2016.

    2014-11-01

    Drawing from controversies between medical, legal, and associative actors about the obligation of sex reassignment surgeries (SRS) for people who intend to change their civil status, this article discusses the role that medical procedures, and particularly SRS, play in contemporary gender identifications and transition pathways in France. In 2010, the French National Institute of Health and Medical Research conducted a national survey in order to study the sociodemographic characteristics, access to medical, and psychological care, and state of health among trans individuals. After a long period of ethnographic work during which a partnership was established with trans actors to map the social, medical, and political landscape of trans communities, a questionnaire was developed and distributed between July and October 2010 in collaboration with most of the trans organizations and public and private health professionals operating in France. Overall, 381 self-identified trans individuals returned the anonymous self-administered questionnaire. The results highlighted the heterogeneity of the trans population, whose definition cannot be reduced to a group of individuals undergoing standardized hormonal treatments and SRS. Two central indicators, sex assigned at birth and gender self-identification, enabled us to describe and analyze different medical and legal pathways with a particular focus on SRS, which is often compulsory for a change of civil status in France. Although SRS remains an important factor in an individual's subjective evaluation of the success of the transition pathway, its practice varies depending on one's sex assigned at birth and gender identification.

    Staff rotation is defined as a reciprocal exchange of staff between two or more clinical areas for a predetermined period of time. The rationale for introducing a 'Critical Care Nurse Rotation Programme' includes important issues such as improving nurses' knowledge and skills, providing development opportunities, networking, the ability to recruit and retain nurses and the provision of a more versatile and flexible workforce. To gain the understanding of nurses' views and opinions on critical care rotation programmes, evidence was collected by means of questionnaires involving 153 critical care nurses and by undertaking semi-structured interviews with four nurses. On the basis of the responses, a pilot of three Critical Care Nurse Rotation Programmes was introduced. An evaluation of the pilot project assessed participants, supervisors and senior nurses' experience of rotation and revealed very positive experiences being reported. The benefits highlighted included improving clinical skills and experience, improving interdepartmental relationships, heightened motivation and opportunities to network. The disadvantages focused on the operational and managerial issues, such as difficulties maintaining supervision and providing an adequate supernumerary period. Evidence from the survey and pilot study suggests that in the future, providing rotational programmes for critical care nurses would be a valuable strategy for recruitment, retention and developing the workforce.

    We compared national prevalence and wealth-related inequality in disability across a large number of countries from all income groups. Data on 218,737 respondents participating in the World Health Survey 2002-2004 were analyzed. A composite disability score (0-100) identified respondents who experienced significant disability in physical, mental, and social functioning irrespective of their underlying health condition. Disabled persons had disability composite scores above 40. Wealth was evaluated using an index of economic status in households based on ownership of selected assets. Socioeconomic inequalities were measured using the slope index of inequality and the relative index of inequality. Median age-standardized disability prevalence was higher in the low- and lower middle-income countries. In all the study countries, disability was more prevalent in the poorest than in the richest wealth quintiles. Pro-rich inequality was statistically significant in 43 of 49 countries, with disability prevalence higher among populations with lower wealth. Median relative inequality was higher in the high- and upper middle-income countries. Integrating equity components into the monitoring of disability trends would help ensure that interventions reach and benefit populations with greatest need.

    Mobile technology ownership in the general US population and medical professionals is increasing, leading to increased use in clinical settings. However, data on use of mobile technology by psychiatry residents remain unclear. In this study, our aim was to provide data on how psychiatric residents use mobile phones in their clinical education as well as barriers relating to technology use. An anonymous, multisite survey was given to psychiatry residents in 2 regions in the United States, including New Orleans and Boston, to understand their technology use. All participants owned mobile phones, and 79% (54/68) used them to access patient information. The majority do not use mobile phones to implement pharmacotherapy (62%, 42/68) or psychotherapy plans (90%, 61/68). The top 3 barriers to using mobile technology in clinical care were privacy concerns (56%, 38/68), lack of clinical guidance (40%, 27/68), and lack of evidence (29%, 20/68). We conclude that developing a technology curriculum and engaging in research could address these barriers to using mobile phones in clinical practice. ©Shih Gipson, John Torous, Robert Boland, Erich Conrad.

    Background To be able to diagnose and treat sepsis better it is important not only to improve the knowledge about definitions and pathophysiology, but also to gain more insight into specialists' perception of, and attitude towards, the current diagnosis and treatment of sepsis. Methods The study was conducted as a prospective, international survey by structured telephone interview. The subjects were intensive care physicians and other specialist physicians caring for intensive care unit (ICU) patients. Results The 1058 physicians who were interviewed (including 529 intensivists) agreed that sepsis is a leading cause of death on the ICU and that the incidence of sepsis is increasing, but that the symptoms of sepsis can easily be misattributed to other conditions. Physicians were concerned that this could lead to under-reporting of sepsis. Two-thirds (67%) were concerned that a common definition is lacking and 83% said it is likely that sepsis is frequently missed. Not more than 17% agreed on any one definition. Conclusion There is a general awareness about the inadequacy of the current definitions of sepsis. Physicians caring for patients with sepsis recognise the difficulty of defining and diagnosing sepsis and are aware that they miss the diagnosis frequently. PMID:15566585

    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

    Although patellofemoral instability is among the most prevalent knee disorders, the management of patients with this condition is complex and remains variable, given the lack of long-term, high-level clinical outcome studies to compare various operative and nonoperative modalities. To discover a consensus within treatment controversies in patellofemoral instability among experienced knee surgeons with a specific interest in the patellofemoral joint. Expert opinion; Level of evidence, 5. A 3-step modified Delphi technique was used to establish a consensus. A 34-question, case-based online survey regarding patellofemoral instability was distributed to all active members of the International Patellofemoral Study Group. Consensus statements were generated if at least 66% of the respondents agreed and then redistributed to the same panel. Modifications to the consensus statements were made based on the iterative feedback process until no discordance was encountered in the third stage. Eight consensus statements were achieved. Nonoperative management is the current standard of care for a first-time dislocation in the absence of an osteochondral fragment or loose body requiring excision (100% agreement). In patients with a first-time dislocation with an operative osteochondral fracture requiring excision or repair, patellar instability should be addressed concurrently (89% agreement). Recurrent instability should be treated surgically, with most surgeons favoring medial reconstruction (77%-86% agreement). While there is general agreement that bony procedures should be performed to correct underlying bony deformities, there is no consensus regarding the most appropriate type of procedure performed. Lateral release should not be performed in isolation for the treatment of patellar instability (89% agreement). Despite the consensus generated in this study, our current understanding remains limited by a lack of high-level evidence as well as the numerous complex variables

    Mizunami underground research laboratory (MIU) is planned to be excavated to the depth of 1000m below the ground surface and is now under construction. One of the most serious problems in a greatly deeper shaft is 'TAKANUKE' collapse caused by slip movement of large discontinuities, as we have reported in the report of 'Study on Collapse Mechanism of Junction between Greatly Deeper Shaft and Horizontal Drifts [JAEA-Research 2008-248 (2008)]'. TAKANUKE collapse has been well known among mining engineers in JAPAN. However, an occurring mechanism of the collapse has not yet been revealed and a design code for it also has not been established. In this report, we have conducted numerical studies using finite difference method in order to throw an objective light on a mechanism of TAKANUKE collapse. These studies show two different stress states in upper and lower side of a large discontinuities. In lower side, a minimum principal stress at shaft wall region drastically reduces due to shaft sinking. This might make shaft wall stability difficult in poor geological condition. Such a TAKANUKE collapse can be found in ventilation shaft projects of the ENASAN tunnel. In the another side of discontinuity, a slip movement along discontinuities takes place due to shaft sinking. This slip movement induces a typical TAKANUKE collapse, as we have reported in 2007. In order to evaluate a possibility of TAKANUKE collapse during MIU main shaft sinking, we have conducted a particle body analysis, which can estimate a brittle failure of hard rock, such as MIU construction site. A fault with a steeply dipping over 79 degree to the main shaft, discovered in a survey boring at MIU site, has a low potential of TAKANUKE collapse during shaft sinking. Beside, a fault with dip of 60 degree may easily slip in a form of TAKANUKE collapse. One CD-ROM is attached as an appendix. (J.P.N.)

    Some studies indicate that older adults lead active lives and travel to many destinations including those not in their immediate residential neighborhoods. We used global positioning system (GPS) devices to track the travel patterns of 40 older adults (mean age: 69) in San Francisco and Los Angeles. Study participants wore the GPS devices for 7 days in fall 2010 and winter 2011. We collected survey responses concurrently about travel patterns. GPS data showed a mean of four trips/day, and a mean trip distance of 7.6 km. Survey data indicated that older adults commonly made trips for four activities (e.g., volunteering, work, visiting friends) at least once each week. Older adults regularly travel outside their residential neighborhoods. GPS can document the mode of travel, the path of travel, and the destinations. Surveys can document the purpose of the travel and the impressions or experiences in the specific locations. © The Author(s) 2013.

    To investigate the ability of cochlear implant (CI) recipients to physically handle and care for their hearing implant device(s) and to identify factors that may influence skills. To assess device management skills, a clinical survey was developed and validated on a clinical cohort of CI recipients. Survey development and validation. A prospective convenience cohort design study. Specialist hearing implant clinic. Forty-nine post-lingually deafened, adult CI recipients, at least 12 months postoperative. Survey test-retest reliability, interobserver reliability and responsiveness. Correlations between management skills and participant demographic, audiometric, clinical outcomes and device factors. The Cochlear Implant Management Skills survey was developed, demonstrating high test-retest reliability (0.878), interobserver reliability (0.972) and responsiveness to intervention (skills training) [t(20) = -3.913, P = 0.001]. Cochlear Implant Management Skills survey scores range from 54.69% to 100% (mean: 83.45%, sd: 12.47). No associations were found between handling skills and participant factors. This is the first study to demonstrate a range in cochlear implant device handling skills in CI recipients and offers clinicians and researchers a tool to systematically and objectively identify shortcomings in CI recipients' device handling skills. © 2015 John Wiley & Sons Ltd.

    Full Text Available Abstract Background The prevalence of tobacco smoking in Germany is high (~27%. Monitoring of national patterns of smoking behaviour and data on the “real-world” effectiveness of cessation methods are needed to inform policies and develop campaigns aimed at reducing tobacco-related harm. In England, the Smoking Toolkit Study (STS has been tracking such indicators since 2006, resulting in the adaptation of tobacco control policies. However, findings cannot be directly transferred into the German health policy context. The German Study on Tobacco Use (DEBRA: “Deutsche Befragung zum Rauchverhalten” aims to provide such nationally representative data. Methods/Design In June 2016, the study started collecting data from computer-assisted, face-to-face household interviews in people aged 14 years and older. Over a period of 3 years, a total of ~36,000 respondents will complete the survey with a new sample of ~2000 respondents every 2 months (=18 waves. This sample will report data on demographics and the use of tobacco and electronic (e-cigarettes. Per wave, about 500–600 people are expected to be current or recent ex-smokers (<12 months since quitting. This sample will answer detailed questions about smoking behaviour, quit attempts, exposure to health professionals’ advice on quitting, and use of cessation aids. Six-month follow-up data will be collected by telephone. Discussion The DEBRA study will be an important source of data for tobacco control policies, health strategies, and future research. The methodology is closely aligned to the STS, which will allow comparisons with data from England, a country with one of the lowest smoking prevalence rates in Europe (18%.

    The prospect of manned space missions out side Earth's or bit is limited by the travel time and shielding against cosmic radiation. The chemical rockets currently used in the space program have no hope of propelling a manned vehicle to a far away location such as Mars due to the enormous mass of fuel that would be required. The specific energy available from nuclear fuel is a factor of 106 higher than chemical fuel; it is there fore obvious that nuclear power production in space is a must. On the other hand, recent considerations to send a man to the Moon for a long stay would require a stable, secured, and safe source of energy (there is hardly anything beyond nuclear power that would provide a useful and reliably safe sustainable supply of energy). National Aeronautics and Space Administration (NASA) anticipates that the mass of a shielding material required for long travel to Mars is the next major design driver. In 2006 NASA identified a need to assess and evaluate potential gaps in existing knowledge and understanding of the level and types of radiation critical to astronauts' health during the long travel to Mars and to start a comprehensive study related to the shielding design of a spacecraft finding the conditions for the mitigation of radiation components contributing to the doses beyond accepted limits. In order to reduce the overall space craft mass, NASA is looking for the novel, multi-purpose and multi-functional materials that will provide effective shielding of the crew and electronics on board. The Laboratory for Neutronics and Geometry Computation in the School of Nuclear Engineering at Purdue University led by Prof. Tatjana Jevremovic began in 2004 the analytical evaluations of different lightweight materials. The preliminary results of the design survey study are presented in this paper. (author)

    Learning styles determine how people manage new information. Evidence-based medicine (EBM) involves the management of information in clinical practice. As a consequence, the way in which a person uses EBM can be related to his or her learning style. In order to tailor EBM education to the individual learner, this study aims to determine whether there is a relationship between an individual's learning style and EBM competence (knowledge/skills, attitude, behaviour). In 2008, we conducted a survey among 140 novice GP trainees in order to assess their EBM competence and learning styles (Accommodator, Diverger, Assimilator, Converger, or mixed learning style). The trainees' EBM knowledge/skills (scale 0-15; mean 6.8; 95%CI 6.4-7.2) were adequate and their attitudes towards EBM (scale 0-100; mean 63; 95%CI 61.3-64.3) were positive. We found no relationship between their knowledge/skills or attitudes and their learning styles (p = 0.21; p = 0.19). Of the trainees, 40% used guidelines to answer clinical questions and 55% agreed that the use of guidelines is the most appropriate way of applying EBM in general practice. Trainees preferred using evidence from summaries to using evidence from single studies. There were no differences in medical decision-making or in EBM use (p = 0.59) for the various learning styles. However, we did find a link between having an Accommodating or Converging learning style and making greater use of intuition. Moreover, trainees with different learning styles expressed different ideas about the optimal use of EBM in primary care. We found that EBM knowledge/skills and EBM attitudes did not differ with respect to the learning styles of GP trainees. However, we did find differences relating to the use of intuition and the trainees' ideas regarding the use of evidence in decision-making.

    Stress in nursing students may be related to attrition from nursing programmes and lead to a shortage of nurses entering clinical careers. In addition, stress leads to psychological morbidity which may have profound adverse consequences for individual nursing students. To follow a cohort of nursing students from entry to their programme to the end of the first year and to study the interrelationship between a range of psychological variables including personality, stress, coping and burnout. Prospective, repeated measures survey using self-administered questionnaires. A university school of nursing in Hong Kong. Students were selected on the basis of entry to their nursing programme in 2004; 158 students entered the study and 147 completed; 37 were male and 121 were female at entry. The mean age of the cohort at entry was 19.1 (S.D. 0.85); ages ranged from 18 to 26. The questionnaires administered at wave 1 were: the NEO Five Factor Inventory, the Coping in Stressful Situations questionnaire, the 12-item General Health Questionnaire, the Maslach Burnout Inventory and the Stress in Nursing Students questionnaire. At wave 2 the 12-item General Health Questionnaire, the Maslach Burnout Inventory and the Stress in Nursing Students questionnaire were administered. Students suffered greater levels of psychological morbidity and burnout at the second time wave and this was largely explained by the personality trait of neuroticism. Stress also increased and this was largely explained by emotion-oriented coping. Undertaking a nursing programme leads to increased level of stress, burnout and psychological morbidity and this is largely related to individual personality and coping traits.

    Residential energy-efficient and renewable energy (EERE) products play an important role in energy conservation and carbon emissions reduction. Various financial incentive programs have been developed to promote the adoption of these products. However, their effectiveness in attracting consumers is not very well understood. In this study, we investigated impacts of financial incentives on homeowner's decision making towards six EERE products. Two forms of incentives, tax credits and interest-free loans, were examined through a household mailing survey in Florida, the United States. Results showed that, although half of the respondents were interested in EERE products, the high investment cost was a major concern that hindered their purchase activities. Homeowners were attracted to financial incentives and valued tax credits much higher than interest-free loans. The current federal home energy tax credit levels were found to attract only 2–12 percent of homeowners to buy EERE products. The willingness of participation was especially low for the costly products (such as solar panels). The participation rate was also very low for lower income (i.e., annual household income below $50,000) families living in older residences. This study contributes to the understanding of economic and social aspects of consumer decision making on energy efficiency and alternative energy. - Highlights: ► We investigated consumer responses to energy efficiency incentives. ► These included tax credits and interest-free loans for six types of energy products. ► We found that tax credits are more effective than interest-free loans. ► The current tax credit rates are insufficient for expensive products (e.g., solar panels). ► A higher amount of incentives is required for the lower-income (<$50 K/yr) households.

    Full Text Available Texting and other cell-phone related distracted driving is estimated to account for thousands of motor vehicle collisions each year but studies examining the specific cell phone reading and writing activities of drivers are limited. The objective of this study was to describe the frequency of cell-phone related distracted driving behaviors. A national, representative, anonymous panel of 1211 United States drivers was recruited in 2015 to complete the Distracted Driving Survey (DDS, an 11-item validated questionnaire examining cell phone reading and writing activities and at what speeds they occur. Higher DDS scores reflect more distraction. DDS scores were analyzed by demographic data and self-reported crash rate. Nearly 60% of respondents reported a cell phone reading or writing activity within the prior 30 days, with reading texts (48%, writing texts (33% and viewing maps (43% most frequently reported. Only 4.9% of respondents had enrolled in a program aimed at reducing cell phone related distracted driving. DDS scores were significantly correlated to crash rate (p < 0.0001, with every one point increase associated with an additional 7% risk of a crash (p < 0.0001. DDS scores were inversely correlated to age (p < 0.0001. The DDS demonstrated high internal consistency (Cronbach's alpha = 0.94. High rates of cell phone-related distraction are reported here in a national sample. Distraction is associated with crash rates and occurs across all age groups, but is highest in younger drivers. The DDS can be used to evaluate the impact of public health programs aimed at reducing cell-phone related distracted driving.

    The purpose of this study was to assess radiographer familiarity and preferences with digital radiography in four teaching hospitals and thereafter make recommendations in line with the migration from screen film to digital radiography. A questionnaire was designed to collect data from either qualified or student radiographers from four teaching hospitals. From the four teaching hospitals, there were a total of 205 potential respondents. Among other things, responses regarding experiences and preferences with digital radiography, quality control procedures, patient dose, advantages and disadvantages of digital radiography were sought. The information collected was based on self-reporting by the participants. The study is exploratory in nature and descriptive statistics were generated from the collected data using Microsoft Excel 2007 and StatsDirect software. Sixty-three out of 205 (31%) radiographers from all the four radiology centers responded to the circulated questionnaire. Only 15% (8) of the qualified radiographers had 4 or more years of experience with digital radiography compared to 68% (36) for the same amount of experience with screen-film radiography. Sixty-one percent (38) of the participants had been exposed to digital radiography during their lectures while at university. A small proportion, 16% (10) of the respondents underwent formal training in quality control procedures on the digital X-ray units they were using. Slightly more than half (55%) of the participants felt it was easier for them to retake an image in digital radiography than in screen film radiography. The results of this survey showed that the participants are familiar with digital radiography and have embraced this relatively new technology as shown by the fact that they can identify both its advantages and disadvantages as applied to clinical practice. However, there are minimal quality control procedures specific to digital radiography being undertaken as such there is need for

    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.

    To evaluate the radiation dose in routine multidetector computed tomography (MDCT) examinations in Italian population. This was a retrospective multicentre study included 5,668 patients from 65 radiology departments who had undergone common CT protocols: head, chest, abdomen, chest-abdomen-pelvis (CAP), spine and cardiac. Data included patient characteristics, CT parameters, volumetric CT dose index (CTDI{sub vol}) and dose length product (DLP) for each CT acquisition phase. Descriptive statistics were calculated, and a multi-regression analysis was used to outline the main factors affecting exposure. The 75th percentiles of CTDI{sub vol} (mGy) and DLP (mGy cm) for whole head were 69 mGy and 1,312 mGy cm, respectively; for chest, 15 mGy and 569 mGy cm; spine, 42 mGy and 888 mGy cm; cardiac, 7 mGy and 131 mGy cm for calcium score, and 61 mGy and 1,208 mGy cm for angiographic CT studies. High variability was present in the DLP of abdomen and CAP protocols, where multiphase examinations dominated (71 % and 73 % respectively): for abdomen, 18 mGy, with 555 and 920 mGy cm in abdomen and abdomen-pelvis acquisitions respectively; for CAP, 17 mGy, with 508, 850 and 1,200 mGy cm in abdomen, abdomen-pelvis and CAP acquisitions respectively. The results of this survey could help in the definition of updated diagnostic reference levels (DRL). (orig.)

    Full Text Available Abstract Background Learning styles determine how people manage new information. Evidence-based medicine (EBM involves the management of information in clinical practice. As a consequence, the way in which a person uses EBM can be related to his or her learning style. In order to tailor EBM education to the individual learner, this study aims to determine whether there is a relationship between an individual's learning style and EBM competence (knowledge/skills, attitude, behaviour. Methods In 2008, we conducted a survey among 140 novice GP trainees in order to assess their EBM competence and learning styles (Accommodator, Diverger, Assimilator, Converger, or mixed learning style. Results The trainees' EBM knowledge/skills (scale 0-15; mean 6.8; 95%CI 6.4-7.2 were adequate and their attitudes towards EBM (scale 0-100; mean 63; 95%CI 61.3-64.3 were positive. We found no relationship between their knowledge/skills or attitudes and their learning styles (p = 0.21; p = 0.19. Of the trainees, 40% used guidelines to answer clinical questions and 55% agreed that the use of guidelines is the most appropriate way of applying EBM in general practice. Trainees preferred using evidence from summaries to using evidence from single studies. There were no differences in medical decision-making or in EBM use (p = 0.59 for the various learning styles. However, we did find a link between having an Accommodating or Converging learning style and making greater use of intuition. Moreover, trainees with different learning styles expressed different ideas about the optimal use of EBM in primary care. Conclusions We found that EBM knowledge/skills and EBM attitudes did not differ with respect to the learning styles of GP trainees. However, we did find differences relating to the use of intuition and the trainees' ideas regarding the use of evidence in decision-making.

    Poorly functioning, time-consuming, and inadequate information systems are among the most important work-related psychosocial factors causing stress in physicians. The present study examined the trend in the perceived stress that was related to information systems (SRIS) among Finnish physicians during a nine-year follow-up. In addition, we examined the associations of gender, age, employment sector, specialization status, leadership position, on-call burden, and time pressure with SRIS change and levels. A longitudinal design with three survey data collection waves (2006, 2010 and 2015) based on a random sample of Finnish physicians in 2006 was used. The study sample included 1095 physicians (62.3% women, mean age 54.4 years) who provided data on SRIS in every wave. GLM repeated measures analyses were used to examine the associations between independent variables and the SRIS trend during the years 2006, 2010, and 2015. SRIS increased during the study period. The estimated marginal mean of SRIS in 2006 was 2.80 (95% CI = 2.68-2.92) and the mean increase was 0.46 (95% CI = 0.30-0.61) points from 2006 to 2010 and 0.25 (95% CI = 0.11-0.39) points from 2010 to 2015. Moreover, our results show that the increase was most pronounced in primary care, whereas in hospitals SRIS did not increase between 2010 and 2015. SRIS increased more among those in a leadership position. On-call duties and high time-pressures were associated with higher SRIS levels during all waves. Changing, difficult, and poorly functioning information systems (IS) are a prominent source of stress among Finnish physicians and this perceived stress continues to increase. Organizations should implement arrangements to ease stress stemming from IS especially for those with a high workload and on-call or leadership duties. To decrease IS-related stress, it would be important to study in more detail the main IS factors that contribute to SRIS. Earlier studies indicate that the usability and stability

    Falls are the leading cause of hip fracture in older women, with important public health implications. Fall risk increases with age and other clinical factors, and varies by race/ethnicity. International studies suggest that fall risk is lower in Asians, although data are limited in U.S. This study examines racial/ethnic differences in fall prevalence among older U.S. women within a large integrated healthcare delivery system. This cross-sectional study used data from 6277 women ages 65-90 who responded to the 2008 or 2011 Kaiser Permanente Northern California Member Health Survey (KPNC-MHS). The KPNC-MHS is a mailed questionnaire sent to a random sample of adult members stratified by age, gender, and geographic location, representing a population estimate of >200,000 women age ≥65 years. Age, race/ethnicity, self-reported health status, presence of diabetes, arthritis or prior stroke, mobility limitations and number of falls in the past year were obtained from the KPNC-MHS. The independent association of race/ethnicity and recent falls was examined, adjusting for known risk factors. The weighted sample was 76.7% non-Hispanic white, 6.2% Hispanic, 6.8% black and 10.3% Asian. Over 20% reported having fallen during the past year (28.5% non-Hispanic white, 27.8% Hispanic, 23.4% black and 20.1% Asian). Older age was associated with greater fall risk, as was having diabetes (OR 1.24, CI 1.03-1.48), prior stroke (OR 1.51, CI 1.09-2.07), arthritis (OR 1.61, CI 1.39-1.85) and mobility limitations (OR 2.82, CI 2.34-3.39), adjusted for age. Compared to whites, Asian (OR 0.64, CI 0.50-0.81) and black (OR 0.73, CI 0.55-0.95) women were much less likely to have ≥1 fall in the past year, adjusting for age, comorbidities, mobility limitation and poor health status. Asians were also less likely to have ≥2 falls (OR 0.62, CI 0.43-0.88). Among older women, the risk of having a recent fall was substantially lower for black and Asian women when compared to white women. This may

    During university, students face some potentially serious health risks, and their lifestyle can have a direct effect on health and health behaviors later in life. Concurrently, university students are digital natives having easy access to the internet and new technologies. Digital health interventions offer promising new opportunities for health promotion, disease prevention, and care in this specific population. The description of the current use of and opinions on digital health among university students can inform future digital health strategies and interventions within university settings. The aim of this exploratory study was to report on university students' use and opinions regarding information and communication technologies for health and well-being, taking into account sociodemographic and self-rated general and mental health correlates. This field survey was conducted from March to April 2017. An informed consent form and a paper questionnaire were given to students aged 18 to 24 years in 4 university campuses in Bordeaux, France. The survey was formulated in 3 sections: (1) sociodemographic characteristics and self-rated general and mental health, (2) information about the use of digital health, and (3) opinions about digital health. Data were analyzed using descriptive statistics and tests of independence. A total of 59.8% (303/507 females) students completed the questionnaire. Concerning digital health use, 34.9% (174/498) had at least 1 health app mostly for physical activity (49.4%, 86/174) and general health monitoring (41.4%, 72/174,), but only 3.9% (20/507) of students had a wearable device. Almost all (94.8%, 450/476) had searched for Web-based health-related information at least once in the last 12 months.

    A survey was conducted for three months among subjects seen in the medical clinics of ABCC, Hiroshima and Nagasaki, to determine the extent of medical x-ray received in ABCC and other hospitals and clinics. Emphasis was chiefly methodological to prepare for later studies designed to evaluate the contribution of medical x-ray to total radiation dose received by survivors of the atomic bombings and controls. The frequency, the institution in which the subject received x-ray, as well as the types of exposure were the prime considerations in the survey. The data were analyzed for each city by sex, age, and exposure status. 2 references, 5 figures, 11 tables.

    Energy education, defined as communication that is designed to influence people's energy usage, has been conducted in one form or another by a wide range of organizations since long before the energy crisis of 1973. Energy education is undertaken by a broad range of public, private, non-profit and utility organizations for a variety of purposes. Each program has a unique message, audience and objectives. Although many energy education programs are still in the early stages of development, some of the programs have been evaluated and show promising results. In an effort to consolidate, describe, and communicate information about the broad range of energy education efforts in this country, a survey was conducted. The surveys were developed to determine who provides energy education, what methods they use, and whether they evaluate the results. The results of the surveys are described and analyzed in the second section of this three-tiered report.

    Reprocessing of data from the seismic reflection survey performed at Finnsjoen in 1987 show that reflection seismics is a viable technique for mapping fracture zones in crystalline rock. Application of state of the art processing algorithms clearly image a gently dipping fracture zone located in the depth interval 200-400 m. In addition, several other reflectors were imaged in the reprocessed section, both gently and steeply dipping ones. Correlations with borehole data indicate that the origin of these reflections are also fractures zones. The data acquisition procedures used at the Finnsjoen survey were basically sound and could, with minor modifications, be applied at other sites. The results indicate that both sources and receivers in future surveys should be placed in boreholes a few meter below the ground surface. 30 refs

    Though survey satisficing, grudging cognitive efforts required to provide optimal answers in the survey response process, poses a serious threat to the validity of online experiments, a detailed explanation of the mechanism has yet to be established. Focusing on attitudes toward immigrants, we examined the mechanism by which survey satisficing distorts treatment effect estimates in online experiments. We hypothesized that satisficers would display more stereotypical responses than non-satisficers would when presented with stereotype-disconfirming information about an immigrant. Results of two experiments largely supported our hypotheses. Satisficers, whom we identified through an instructional manipulation check (IMC), processed information about immigrants' personality traits congruently with the stereotype activated by information provided about nationality. The significantly shorter vignette reading time of satisficers corroborates their time-efficient impression formation based on stereotyping. However, the shallow information processing of satisficers can be rectified by alerting them to their inattentiveness through use of a repeated IMC. PMID:27803680

    During interventional radiology (IR) and cardiology (IC) procedures, medical staff can receive high doses to their eye lenses. The Retrospective Evaluation of Lens Injuries and Dose study organized in Argentina in 2010 found incipient opacity in 50% of IC physicians and 41% of IC technicians/nurses. These results, added to the recommendations of the International Commission on Radiological Protection, which lowered their former occupational equivalent dose limit for the lens, led us to assess the eye lens dose, Hp(3), during interventional procedures. To this end, a new dosemeter was designed and calibrated at the National Atomic Energy Commission of Argentina to evaluate Hp(3). Personal dose equivalent (Hp(10)), and Hp(3) were assessed for 3 months in two IC and IR departments. An Alderson phantom was used to simulate monthly exposures of five occupational staff members. Hp(3) and Hp(10) were obtained monthly for 14 occupational staff members exposed to 121 IR and IC procedures. We concluded that the annual effective dose and Hp(3) were lower than 0.3 and 10 mSv, respectively and the average cumulative Hp(3) for working life was lower than 400 and 200 mSv for physicians and technicians/scrub nurse, respectively. An occupational annual dose constraint of 0.3 mSv was calculated. - Highlights: • An eye lens dosimeters was designed at the Personal Dosimetry Laboratory of CNEA. • A successful dosimetric survey in two interventional departments was done. • The annual effective dose and the annual eye lens dose are lower than the ICRP dose thresholds. • In order to reduce doses actions should be promoted to maximize radiation protection

    The aim of this study was to assess the outsourcing situation in Taiwanese hospitals and compares the differences in hospital ownership and in accreditation levels. This research combined two kinds of methods: a questionnaire survey and the in-depth interview to two CEOs of the sample hospitals. One hospital is not-for-profit, while the other is a public hospital and the research samples are from the hospital data from Taiwan's 2005 to 2007 Department of Health qualifying lists of hospital accreditation. The returned questionnaires were analyzed with STATISTICA 7.1 version software. The results for non-medical items showed medical waste and common trash both have the highest rate (94.6 percent) of being outsourced. The gift store (75 percent) and linen (73 percent) follow close behind, while the lowest rate of outsourcing is in utility maintenance (13.5 percent). For medical items, the highest rate of outsourcing is in the ambulance units (51.4 percent), while the hemodialysis center follows close behind with a rate of 50 percent. For departments of nutrition, pharmacy, and nursing however, the outsourcing rate is lower than 3 percent. This shows that Taiwan's hospitals are still conservative in their willingness to outsource for medical items. The results of the satisfaction paired t-test show that the non-medical items have a higher score than the medical items. The factor analysis showed the three significant factors in of non medical items' outsourcing are "performance", "finance", and "human resource". For medical items, the two factors are "operation" and satisfaction". To further exam the factor validity and reliability of the satisfaction model, a confirmative factor analysis (CFA) was conducted using structure equation modeling (SEM) method and found the model fitting well. Hospitals, especially for public hospitals, can get benefits from outsourcing to revive the full-time-equivalent and human resource limitation.

    Highlights: • EVs have been greatly developed with a series of encouraging policies. • The maxi mileages and braking performance still needs further improvement. • More residential and public charging piles should be in the plan and design. • APP oriented information of charging station need to be researched and developed. - Abstract: The private motor vehicles are significantly important means of transportation in modern lifestyle, however, these also contribute to a large proportion of the total air pollution and primary energy consumption. In order to develop green transportation system, it becomes imperative to use integrated technologies to achieve reduced emissions and utilize renewable energy. Electric vehicles (EVs) have been considered as one of these technologies to transform the traditional vehicle mix. However, the uptake of EV has been debated on factors like cost, performance (autonomous mileage), charging point infrastructure construction, energy saving, policy and end users’ adaptation. Present study investigates the technology feasibility (which usually refer to EVs’ cost, EV charging, supplier’s customer services quality, EV travel performance) and users’ adaptation of EV in Beijing, which is a key driver for the EV uptake into the Beijing transportation system. The relevant data have been collected and analyzed in the form of questionnaire survey around all of these factors. While considering the user perception and satisfaction, safety of charging and energy bills have also been investigated. According to the data analysis, it has been found the policy of ‘No traffic restrictions for EVs’ (the traffic restrictions means for certain date, from Monday to Friday the motor vehicles with the last register number of 1 and 6, 2 and 7, 3 and 8, 4 and 9, 5 and 0, are restricted to travel, respectively), the availability of the charging infrastructure and technical support are the most significant factors affecting the users

    Out-of-hours primary care has been provided by general practitioner (GP) cooperatives since the year 2000 in the Netherlands. Early studies in countries with similar organizational structures showed positive GP experiences. However, nowadays it is said that GPs experience a high workload at the cooperative and that they outsource a considerable part of their shifts. To examine positive and negative experiences of GPs providing out-of-hours primary care, and the frequency and reasons for outsourcing shifts. A cross-sectional observational survey among 688 GPs connected to six GP cooperatives in the Netherlands, using a web-based questionnaire. The response was 55% (n = 378). The main reasons for working in GP cooperatives were to retain registration as GP (79%) and remain experienced in acute care (74%). GPs considered the peak hours (81%) and the high number of patients (73%) as the most negative aspects. Most GPs chose to provide the out-of-hours shifts themselves: 85% outsourced maximally 25% of their shifts. The percentage of outsourced shifts increased with age. Main reasons for outsourcing were the desire to have more private time (76%); the high workload in daytime practice (71%); and less the workload during out-of-hours (46%). GPs are motivated to work in out-of-hours GP cooperatives, and they outsource few shifts. GPs consider the peak load and the large number of (non-urgent) help requests as the most negative aspects. To motivate and involve GPs for 7 × 24-h primary care, it is important to set limits on their workload.

    Many people with a mental illness are parents caring for dependent children. These children are at greater risk of developing their own mental health concerns compared to other children. Mental health services are opportune places for healthcare professionals to identify clients' parenting status and address the needs of their children. There is a knowledge gap regarding Thai mental health professionals' family-focused knowledge and practices when working with parents with mental illness and their children and families. This cross -sectional survey study examined the attitudes, knowledge and practices of a sample (n = 349) of the Thai mental health professional workforce (nurses, social workers, psychologists, psychiatrists) using a translated version of the Family-Focused Mental Health Practice Questionnaire (FFMHPQ). The majority of clinicians reported no training in family (76.8%) or child-focused practice (79.7%). Compared to other professional groups, psychiatric nurses reported lower scores on almost all aspects of family-focused practice except supporting clients in their parenting role within the context of their mental illness. Social workers scored highest overall including having more workplace support for family-focused practice as well as a higher awareness of family-focused policy and procedures than psychiatrists; social workers also scored higher than psychologists on providing support to families and parents. All mental health care professional groups reported a need for training and inter-professional practice when working with families. The findings indicate an important opportunity for the prevention of intergenerational mental illness in whose parents have mental illness by strengthening the professional development of nurses and other health professionals in child and family-focused knowledge and practice.

  3. Physicians' personal values in determining medical decision-making capacity: a survey study.

    Decision-making capacity (DMC) evaluations are complex clinical judgements with important ethical implications for patients' self-determination. They are achieved not only on descriptive grounds but are inherently normative and, therefore, dependent on the values held by those involved in the DMC evaluation. To date, the issue of whether and how physicians' personal values relate to DMC evaluation has never been empirically investigated. The present survey study aimed to investigate this question by exploring the relationship between physicians' value profiles and the use of risk-relative standards in capacity evaluations. The findings indicate that physicians' personal values are of some significance in this regard. Those physicians with relatively high scores on the value types of achievement, power-resource, face and conformity to interpersonal standards were more likely to apply risk-relative criteria in a range of situations, using more stringent assessment standards when interventions were riskier. By contrast, those physicians who strongly emphasise hedonism, conformity to rules and universalism concern were more likely to apply equal standards regardless of the consequences of a decision. Furthermore, it has been shown that around a quarter of all respondents do not appreciate that their values impact on their DMC evaluations, highlighting a need to better sensitise physicians in this regard. The implications of these findings are discussed, especially in terms of the moral status of the potential and almost unavoidable influence of physicians' values.

    Extensive microearthquake studies have been conducted in Egypt as a joint project between scientists from the Egyptian Geological Survey and Mining Authority (EGSMA) and U.S. scientists. At this stage, a great part of the data has been analyzed and two intensively active areas have been located: one in the Abu Dabbab area of the Eastern Desert, the second at the mouth of the Gulf of Suez near Gubal Island (Daggett et al., 1980). Both sites have been reported to be the epicenters of large earthquakes in 1955 and 1969, respectively. A few scattered earthquakes have also been located in the northern part of the Red Sea, some of which lie along its median axis (Daggett et al., 1986) adding to evidence for the medial opening of the northern Red Sea. After the occurrence of an earthquake (M = 5.5) in the Aswan region on 14 November 1981, continuous recording of the many aftershocks was carried out by EGSMA for about seven months from December 1981 to July 1982, when the temporary network was replaced by a network of telemetered seismographs installed and operated by Helwan Institute of Astronomy and Geophysics in cooperation with scientists from Lamont and Doherty Geological Observatory (LDGO). The majority of epicenters are concentrated in the vicinity of G. Marawa about 65 km upstream of Aswan Dam, along the E-W Kalabsha fault. The observed focal mechanism is consistent with a right-lateral strike-slip motion on the Kalabsha fault. Analysis of Aswan microearthquakes has been done by EGSMA in cooperation with scientists from California Division of Mines and Geology (CDMG).

    Musical theater performers are the "triathletes" in the performing arts. The field requires versatility in a combination of skills including dancing, singing, and drama in a high frequency of performances. The aim of this study was to analyze and evaluate the health situation of musical theater students using a complete musical educational institute as an example (n = 37). The basis for the evaluation was a questionnaire survey (standardized F 1000). All students of the school participated (20 males, 17 females). Of the students, 62% have a part-time job for financial reasons, and 67.7% state only a "partial satisfaction" with their body. Regarding injury, 45.9% claim to sustain an orthopaedic injury up to twice a year, and 29.7% up to three or four times. A total of 49 acute injuries (1.3/student) and 42 chronic complaints (1.1/student) were stated. The lower extremity was the most common acutely injured region (65.3%), followed by the spine (16.3%) and upper extremity (14.3%). Of chronic complaints, the lumbar spine was the most commonly affected area, followed by the hip joint and pelvic area. Thirty-three and 24% of acute injuries occurred during "spins" and/or "stretching," respectively. There were various causes for physical and mental problems. The results show both parallels and differences to the relevant literature. It is shown that health hazards already arise in the education of musical performers. This provides particulars for the implementation of injury prevention measures during the theoretical and practical education of musical students.

    Full Text Available Aerial surveys of marine mammals are routinely conducted to assess and monitor species' habitat use and population status. In Australia, dugongs (Dugong dugon are regularly surveyed and long-term datasets have formed the basis for defining habitat of high conservation value and risk assessments of human impacts. Unmanned aerial vehicles (UAVs may facilitate more accurate, human-risk free, and cheaper aerial surveys. We undertook the first Australian UAV survey trial in Shark Bay, western Australia. We conducted seven flights of the ScanEagle UAV, mounted with a digital SLR camera payload. During each flight, ten transects covering a 1.3 km(2 area frequently used by dugongs, were flown at 500, 750 and 1000 ft. Image (photograph capture was controlled via the Ground Control Station and the capture rate was scheduled to achieve a prescribed 10% overlap between images along transect lines. Images were manually reviewed post hoc for animals and scored according to sun glitter, Beaufort Sea state and turbidity. We captured 6243 images, 627 containing dugongs. We also identified whales, dolphins, turtles and a range of other fauna. Of all possible dugong sightings, 95% (CI = 90%, 98% were subjectively classed as 'certain' (unmistakably dugongs. Neither our dugong sighting rate, nor our ability to identify dugongs with certainty, were affected by UAV altitude. Turbidity was the only environmental variable significantly affecting the dugong sighting rate. Our results suggest that UAV systems may not be limited by sea state conditions in the same manner as sightings from manned surveys. The overlap between images proved valuable for detecting animals that were masked by sun glitter in the corners of images, and identifying animals initially captured at awkward body angles. This initial trial of a basic camera system has successfully demonstrated that the ScanEagle UAV has great potential as a tool for marine mammal aerial surveys.

    In 2009, Ministry of Education, Culture, Sports, Science and Technology(MEXT) started the survey system development for Hydrothermal deposit. We proposed the Vertical Cable Seismic (VCS), the reflection seismic survey with vertical cable above seabottom. VCS has the following advantages for hydrothermal deposit survey. . (1) VCS is an effective high-resolution 3D seismic survey within limited area. (2) It achieves high-resolution image because the sensors are closely located to the target. (3) It avoids the coupling problems between sensor and seabottom that cause serious damage of seismic data quality. (4) Various types of marine source are applicable with VCS such as sea-surface source (air gun, water gun etc.) , deep-towed or ocean bottom sources. (5) Autonomous recording system. Our first experiment of 2D/3D VCS surveys has been carried out in Lake Biwa, JAPAN. in November 2009. The 2D VCS data processing follows the walk-away VSP, including wave field separation and depth migration. The result gives clearer image than the conventional surface seismic. Prestack depth migration is applied to 3D data to obtain good quality 3D depth volume. Uncertainty of the source/receiver poisons in water causes the serious problem of the imaging. We used several transducer/transponder to estimate these positions. The VCS seismic records themselves can also provide sensor position using the first break of each trace and we calibrate the positions. We are currently developing the autonomous recording VCS system and planning the trial experiment in actual ocean to establish the way of deployment/recovery and the examine the position through the current flow in November, 2010. The second VCS survey will planned over the actual hydrothermal deposit with deep-towed source in February, 2011.

    The participation rate in the Danish National Health Survey (DNHS) 2010 was significantly lower among ethnic minorities than ethnic Danes. The purpose was to characterize nonresponse among ethnic minorities in DNHS, analyze variations in item nonresponse, and investigate barriers and incentives to participation. This was a mixed-method study. Logistic regression was used to analyze nonresponse using data from DNHS (N = 177,639 and chi-square tests in item nonresponse analyses. We explored barriers and incentives regarding participation through focus groups and cognitive interviews. Informants included immigrants and their descendants of both sexes, with and without higher education. The highest nonresponse rate was for non-Western descendants (80.0%) and immigrants 25 (72.3%) with basic education. Immigrants and descendants had higher odds ratios (OR = 3.07 and OR = 3.35, respectively) for nonresponse than ethnic Danes when adjusted for sex, age, marital status, and education. Non-Western immigrants had higher item nonresponse in several question categories. Barriers to non-participation related to the content, language, format, and layout of both the questionnaire and the cover letter. The sender and setting in which to receive the questionnaire also influenced answering incentives. We observed differences in barriers and incentives between immigrants and descendants. Nonresponse appears related to linguistic and/or educational limitations, to alienation generated by the questions' focus on disease and cultural assumptions, or mistrust regarding anonymity. Ethnic minorities seem particularly affected by such barriers. To increase survey participation, questions could be sensitized to reflect multicultural traditions, and the impact of sender and setting considered.

    This project aims to characterize chemical and subsequently odor emissions from a digester plant located closed to Boraas in Sweden (Boraas Energi och Miljoe AB). The digestion produces mainly 2 by-products, biogas and high quality organic biofertilizer. Biogas is a renewable source of electrical and heat energy and subsequently digester have a promising future. Unfortunately, release of unpleasant odours is one of the problems that may limit development of the technique as odours strongly influence the level of acceptance of the neighbours. The number of complaints due to odours depends mostly, upon the degree of odour release, the weather condition and plant environment (which influence the risks for spreading out), and the tolerance of the neighbours. These parameters are strongly variable. Many processes inside the plant distributed on a large surface may contribute to odour release. Chemical emissions were studied, in this project, by extensive sampling inside the plant. Results were then evaluated regarding risk for odour releases. The goal was to suggest controls and routines to limit releases. The conditions leading to the higher risks for odour emissions were studied by performing sampling at different periods of the year and subsequently different weather conditions. At first, places for measurement were chosen together with personal of the plant. Three zones are considered to mainly contribute to the odour emissions: the landfill region, the cisterns region and the leaching lake region. Totally 13 places were studied with regard to odour and chemical emissions under 2008-2009 at different weather conditions. Some results from a previous project (2007) are also presented here. Results show that the spreading out of can be maintained to an acceptable level as long as the plant is functioning without disturbances. The early stages of the treatment of waste should be confined in locals with closed doors to avoid spreading out of odours. Through controlled

    There is considerable potential for mobile technologies to empower pediatric patients and families by improving their communication with health professionals. National surveys suggest minority parents frequently communicate via mobile technology, but it is uncertain how amenable they are to receiving health care information in this format. Although the low cost and far reach characteristics of mobile health (mHealth) technology makes it advantageous for communication with minority parents, data on acceptance are needed. The objective of the study was to determine utilization of mobile and Internet technology by African American parents in an urban, underserved population, and to assess their interest in receiving health information via text messaging or other technologies (eg, social media and the Internet). A survey was administered to parents of children aged 1-12 years covered by public insurance receiving care at 3 pediatric primary care centers in Washington, DC. The African American sample (N=302) was composed of primarily single (75.8%, 229/302) mothers. Almost half had more than a high school education (47.7%, 144/302) and incomes above US $25,000 per year (43.0%, 130/302). Most (97.0%, 293/302) reported owning a cell phone, of which 91.1% (275/302) used it to text and 78.5% (237/302) used it to access the Internet. Most had service plans with unlimited text and data, but 26.5% (80/302) experienced service interruptions in the previous year. Home Internet access was more prevalent among those with higher income (86.2%, 112/130), but it was still relatively pervasive among lower income families (66.9%, 83/124). In adjusted logistic regression models, African American mothers with income greater than US $25,000 annually were 4 times as likely to own a tablet computer than their lower income counterparts. Of the participants, 80.8% (244/302) used social networking, primarily Facebook, and 74.2% (224/302) were interested in joining a social networking group

    Sexual and gender minority adolescents represent an understudied and hard-to-reach population who experience higher rates of mental and behavioral health problems in comparison to their cisgender, heterosexual peers. Online surveys and the proliferation of Internet-connected devices among adolescents offer an exciting opportunity for researchers to begin addressing research gaps and past methodological limitations with these hard-to-reach populations. The purpose of this article is to provide guidance to researchers who are designing and implementing anonymous, incentivized, online surveys by examining the following critical domains-(a) recruitment and engagement: means of leveraging social media and videos to recruit and engage a more nationally representative sample; (b) safety and protection: strategies for administering informed consent and protecting participant anonymity and well-being; and (c) data integrity: mechanisms to detect dishonest and repeat responders. To facilitate discussion of these aims, concrete examples are used from SpeakOut-a 3-year, national study funded by the National Institute of Justice that utilized an anonymous, incentivized, online survey with a large sample of sexual and gender minority adolescents ( N = 1,177) to identify the prevalence, incidence, and correlates of polyvictimization. The article concludes with lessons learned from this national study and recommendations for technological innovations and future research that will strengthen the utility of anonymous, incentivized, online surveys to study sexual and gender minority adolescents and other hard-to-reach populations.

    An operating room (OR) environment is challenging and complicated. At any given time, several vital tasks are being performed by skilled individuals, including physicians, nurses, and ancillary staff. There is a potential for multifactorial mistakes; many arise because of communication issues. To evaluate the current state of perceptions of interdisciplinary communication in an OR setting, a survey was developed and administered to four academic residency training departments of anesthesiology in a single U.S. state. The results of this survey show that perceived poor communication within the OR leads to a lack of emphasis on a multidisciplinary approach to patient care in the OR. Survey data can be used internally to identify shortcomings in communication at a facility, to stress the importance of communication, and to serve as a powerful education tool to potentially improve patient care. Through this type of survey, which emphasizes communication in the OR, stakeholders can work more effectively to improve patient care and decrease adverse outcomes in the hospital environment.

    The practice of office-based surgery is increasing in many specialties. Using Mohs surgery as a model, we investigated the role of ergonomics in office-based surgery to limit work-related musculoskeletal disorders. All Mayo Clinic surgeons currently performing Mohs surgery and Mohs surgeons trained at Mayo Clinic between 1990 and 2004 received a questionnaire survey between May 2003 and September 2004. A sample of respondents were videotaped during surgery. The main outcome measures were survey responses and an ergonomist's identification of potential causes of musculoskeletal disorders. All 17 surgeons surveyed responded. Those surveyed spend a mean of 24 hours per week in surgery. Sixteen said they had symptoms caused by or made worse by performing surgery. Symptom onset occurred on average at age 35.4 years. The most common complaints were pain and stiffness in the neck, shoulders, and lower back and headaches. Videotapes of 6 surgeons revealed problems with operating room setup, awkward posture, forceful exertion, poor positioning, lighting, and duration of procedures. Symptoms of musculoskeletal injuries are common and may begin early in a physician's career. Modifying footwear, flooring, table height, operating position, lighting, and surgical instruments may improve the ergonomics of office-based surgery.

    The aim of this study was the assesment of psychometric properties of the Portuguese version of the instrument "Medical Outcomes Study - Social Support Survey (MOSSSS)". This questionnaire has been translated and adapted in a Portuguese sample of 101 patients with chronic illness of a rural health centre in Portugal. The average age of patients was 63.4 years, 56.4% female. 29% were illiterate and 2% had completed high school. 78% had arterial hypertension and the 56.4% had diabetes mellitus type 2. The internal consistency was evaluated using Cronbach's alpha. Exploratory and Confirmatory factor analysis were performed in order to confirm reliability and validity of the scale and its multidimensional characteristics. The 2-week test-retest reliability was estimated using weighted kappa for the ordinals variables and intraclass coefficient correlation for the quantitative variables. Cronbach's alphas for the subscales ranged from 0.873 to 0.967 at test, and 0.862 to 0.972 at retest. Exploratory factor analysis revealed the existence of four factors (emotional, tangible, positive interaction and affection support) that explain the 72.71% of the variance. Confirmatory factor analysis supported the existence of four factors that allowed the application of the scale with original items. The goodness-of-fit measures corroborate the initial structure, with chi2/ df=2.01, GFI=0.998, CFI=0.999, AGFI=0.998, TLI=0.999, NFI=0.998, SRMR=0.332, RMSEA=0.76. The 2-weeks test-retest reliability of the Portuguese MOS-SSS as measured by the intraclass correlation coefficient was ranged from 0.941 to 0.966 for the four dimensions and the overall support index. The weighted kappa was ranged from 0.67 to 0.87 for all the items. The MOS-SSS Portuguese version demonstrates good psychometric properties and seems to be useful to measure multidimensional aspects of social support in the Portuguese population.

    There are no guidelines for when surgeons should allow patients to return to sports and athletic activities after spinal fusion for adolescent idiopathic scoliosis (AIS). Current recommendations are based on anecdotal reports and a survey performed more than a decade ago in the era of first/second-generation posterior implants. To identify current recommendations for return to sports and athletic activities after surgery for AIS. Questionnaire-based survey. Adolescent idiopathic scoliosis after corrective surgery. Type and time to return to sports. A survey was administered to members of the Spinal Deformity Study Group. The survey consisted of surgeon demographic information, six clinical case scenarios, three different construct types (hooks, pedicle screws, hybrid), and questions regarding the influence of lowest instrumented vertebra (LIV) and postoperative physical therapy. Twenty-three surgeons completed the survey, and respondents were all experienced expert deformity surgeons. Pedicle screw instrumentation allows earlier return to noncontact and contact sports, with most patients allowed to return to running by 3 months, both noncontact and contact sports by 6 months, and collision sports by 12 months postoperatively. For all construct types, approximately 20% never allow return to collision sports, whereas all surgeons allow eventual return to contact and noncontact sports regardless of construct type. In addition to construct type, we found progressively distal LIV resulted in more surgeons never allowing return to collision sports, with 12% for selective thoracic fusion to T12/L1 versus 33% for posterior spinal fusion to L4. Most respondents also did not recommend formal postoperative physical therapy (78%). Of all surgeons surveyed, there was only one reported instrumentation failure/pullout without neurologic deficit after a patient went snowboarding 2 weeks postoperatively. Modern posterior instrumentation allows surgeons to recommend earlier return

    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. ©Elizabeth Fearon, Sungai T Chabata, Jennifer A Thompson, Frances M Cowan, James R Hargreaves.

    Spatial neglect (SN) impedes rehabilitation success and leaves long-term consequences. We asked experts to provide their opinions in addressing SN by scenario (ideal vs. reality) and by recovery phase (earliest, acute, subacute, and chronic). Experts were individuals who have assessed or treated patients with SN clinically. This study was conducted using an anonymous survey on the Internet with 189 responders over 3 months. Located in 23 different countries, 127 experts of seven disciplines were included (occupational therapy, physical therapy, nursing, speech and language pathology or therapy, neurology, physical medicine and rehabilitation, and psychology or neuropsychology). Comparing the two scenarios, more treatments were selected in the ideal than in the reality scenario for all recovery phases except for the chronic phase. In both scenarios, (1) more treatments were selected in acute and subacute phases than in earliest or chronic phases, (2) less experienced experts selected diverse treatment options more often, and (3) highly experienced experts were more likely to provide their reasons of treatment selection, suggestions of treatment delivery methods, and other insights. Finally, 83.7% reported obstacles in treating SN. Experts' treatment selections are consistent with current evidence and practice guidelines. Recognizing the limitation of evidence, their opinions may help generate ideas in various topics (e.g., dosing, integrative intervention, and treatment implementation) to be examined in future studies. Implications for Rehabilitation Clinicians with experience in treating people with spatial neglect (i.e., experts as defined in the present study) recognized the limitation of evidence but nonetheless suggested specific treatments by recovery phase. In both the reality and ideal scenarios, experts included visual scanning, active limb activation, and sustained attention training in the top-five selections. Prism adaptation was in the top

  3. A Comprehensive Study of ULIRGs in the Herschel Very Wide Field Surveys

    Science.gov (United States)

    Yan, Haojing

    Extreme starbursting galaxies exist at all redshifts, and most of them are so heavily obscured by dust that they are Ultra-Luminous InfraRed Galaxies (ULIRGs) while being faint in optical to near-IR. The latest example is at record-high z=6.337, approaching the end of the reionization. There have been numerous suggestions that understanding ULIRG is critical in constructing a comprehensive picture of galaxy formation history. These range from the hypothesis three decades ago that the ULIRG phase is the prelude to QSO and large ellipticals, to the recent tentative evidence that ULIRG could make a large (if not dominant) contribution to the global star formation rate density (GSFRD) at z>1. However, the exact nature of ULIRG and their role in galaxy assembly still remain illusive, largely due to the limited sample size and the severe source confusion problem in the far-IR (FIR). The very wide field surveys by Herschel have provided the best opportunity to date to systematically study ULIRG beyond the local universe, most importantly because of their wide coverage and high sensitivity to probe large volumes to high redshifts and the multiple FIR bands that allow for direct measurement of the IR luminosities. We propose to construct the largest possible ULIRG sample in these fields at all redshifts, and to study the evolution of ULIRGs. We will concentrate on the HerMES, the H-ATLAS and the HerS programs whose data are already public. While the confusion problem still persists in these Herschel data, we have demonstrated that it is possible to directly use the position priors from optical images to decompose the candidate contributors to a given Herschel source if its S/N suffices (Yan et al. 2014). This is a significant improvement over previous studies where higher-resolution mid-IR (mostly Spitzer MIPS 24-micron) data had to be used as the proxies to the FIR source locations, because (1) such proxy images also suffer from the blending problem in the first place and

    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.

    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.

    The measurement of patient satisfaction is crucial to enhancing customer service and competitive advantage in the health-care industry. While there are numerous approaches to such measurement, this paper provides a case study which compares and contrasts patient and staff perceptions of customer service using both survey and focus group data. Results indicate that there is a high degree of correlation between staff and patient perceptions of customer service based on both survey and focus group data. However, the staff and patient subgroups also provided complementary information regarding patient perceptions of their service experience. Staff members tended to have more negative perceptions of service attributes than did the patients themselves. The focus group results provide complementary information to survey results in terms of greater detail and more managerially relevant information. While these results are derived from a pilot study, they suggest that diversification of data sources beyond patient surveys may enhance the utility of customer service information. If further research can affirm these findings, they create exciting possibilities for gathering valid, reliable and cost-effective customer service information.

    Full Text Available An initial census of layer farms in Khartoum State, Sudan, was carried out in late 2007 and early 2008 and found that there were 252 layer farms with a total population of 2 221 800 birds. This paper reports the findings of the census. Based on this information, a structured questionnaire survey of 92 farms was then conducted in the state in April 2008 to collect data on antibiotic usage, demographic data and public health awareness. Ninety-eight per cent of participating farms comprised open-sided houses. It was found that 49% of the farms surveyed were on antibiotic treatment when the survey was conducted, whilst 59% of the farms had used antibiotics within the last 3 months. The study found that farmers and producers had a lack of knowledge about antimicrobial residues, their withdrawal periods and the risk posed by the consumption of these residues. The study also concluded that traditional farming systems in Sudan relied heavily on antimicrobial medication to control disease and almost half of the farms surveyed were treating their flocks with antimicrobials. In addition to this, there was a lack of disease control programmes which probably resulted in a massive use of antibiotics to control endemic diseases. This was further compounded by the absence of governmental supervision and control on the use of drugs.

    collected in general population surveys, given the nature of such surveys. While researchers can glean information from survey data such as functional health and disability, social inclusion or exclusion, and the role of social determinants in the lives of these children and their families, administrative data can identify rare neurodevelopmental conditions and disabilities not captured in general surveys. Analyzing information from all these sources can lead to a more nuanced understanding of the economic and social impacts, and functional limitations in daily living, that patients and their families experience with certain neurodevelopmental conditions and disabilities. Statistics Canada surveys offer a plethora of information for researchers interested in neurodevelopmental disabilities and social determinants of health. As these surveys are national in their scope, they provide a wealth of information for statistical analysis from people across Canada. This information can be used to inform researchers, policy makers, and families of people who live with neurodevelopmental conditions and disabilities. For example, sophisticated microsimulation modelling techniques have been conducted to project the health and economic impacts from such disabilities 20 years into the future. Such projections will be vital for policy-makers tasked with designing services and programs to assist these people. Much work remains to be done, however. Statistics Canada has already begun working on the potential for using administrative data to conceptualize childhood disability, as well as using data that has been anonymized in national administrative databases to study the health of Canada’s children. These are excellent bases from which to build future research.

Important barriers are the identification of patients for palliative care and the organization of such care in this patient group. Objective: Pulmonologists have a central role in providing good quality palliative care for patients with COPD. To guide future research and develop services, their view on palliative care for these patients was explored. Methods: A survey study was performed by the members of the Netherlands Association of Physicians for Lung Diseases and Tuberculosis. Results: The 256 respondents (31.8% covered 85.9% of the hospital organizations in the Netherlands. Most pulmonologists (92.2% indicated to distinguish a palliative phase in the COPD trajectory, but there was no consensus about the different criteria used for its identification. Aspects of palliative care in COPD considered important were advance care planning conversation (82%, communication between pulmonologist and general practitioner (77%, and identification of the palliative phase (75.8%, while the latter was considered the most important aspect for improvement (67.6%. Pulmonologists indicated to prefer organizing palliative care for hospitalized patients with COPD themselves (55.5%, while 30.9% indicated to prefer cooperation with a specialized palliative care team (SPCT. In the ambulatory setting, a multidisciplinary cooperation between pulmonologist, general practitioner, and a respiratory nurse specialist was preferred (71.1%. Conclusion: To encourage pulmonologists to timely initiate palliative care in COPD, we recommend to conduct further research into more specific identification

    On average, 570 million users, 93% in China's first-tier cities, log on to WeChat every day. WeChat has become the most widely and frequently used social media in China, and has been profoundly integrated into the daily life of many Chinese people. A variety of health-related information may be found on WeChat. The objective of this study is to understand how the general public views the impact of the rapidly emerging social media on health information acquisition. A self-administered questionnaire was designed, distributed, collected, and analyzed utilizing the online survey tool Sojump. WeChat was adopted to randomly release the questionnaires using convenience sampling and collect the results after a certain amount of time. (1) A total of 1636 questionnaires (WeChat customers) were collected from 32 provinces. (2) The primary means by which respondents received health education was via the Internet (71.79%). Baidu and WeChat were the top 2 search tools utilized (90.71% and 28.30%, respectively). Only 12.41% of respondents were satisfied with their online health information search. (3) Almost all had seen (98.35%) or read (97.68%) health information; however, only 14.43% believed that WeChat health information could improve health. Nearly one-third frequently received and read health information through WeChat. WeChat was selected (63.26%) as the most expected means for obtaining health information. (4) The major concerns regarding health information through WeChat included the following: excessively homogeneous information, the lack of a guarantee of professionalism, and the presence of advertisements. (5) Finally, the general public was most interested in individualized and interactive health information by managing clinicians, they will highly benefit from using social media rather than Internet search tools. The current state of health acquisition proves worrisome. The public has a high chance to access health information via WeChat. The growing popularity of

    It is well established that high ambient heat could cause congenital abnormalities resulting in miscarriage or stillbirth among certain species of mammals. However, this has not been systematically studied in real field settings among humans, despite the potential value of such knowledge for estimating the impact of global warming on the human species. This study sought to test the hypothesis that maternal heat exposure during pregnancy in hot regions is associated with increased prevalence of spontaneous abortions or stillbirths and to develop an analytical strategy to use existing data from maternal health surveys and existing data on historical heat levels at a geographic grid cell level. A subsample of the Ghana Maternal Health Survey 2007 was used in this study. This study sample consisted of 1136 women with pregnancy experiences between 2004 and 2007, out of which 141 women had a pregnancy that terminated in miscarriage or stillbirth. Induced-abortion cases were excluded. The linkage between ambient heat exposure and pregnancy outcome followed the epidemiological time-place-person principle, by linking timing of pregnancy outcome with historical data of local area heat levels for each month, as estimated in an international database. Maternal heat exposure level was estimated using calculated levels of the wet-bulb globe temperature (WBGT), which takes into account temperature, humidity, heat radiation, and air movement over the skin (wind speed). The values we used applied to exposure in the shade or in buildings without cooling (no solar heat radiation) and a standard air movement of 1 m/s. We applied two exposure durations: yearly average and monthly average for second month of pregnancy. In one analysis, we restricted the sample to four regions with time-homogeneous ambient heat. Analysis was made using logistic regression. About 12% of the latest pregnancies ended in either miscarriage (9.6%) or stillbirth (2.8%). The odds ratios indicated 12 to 15

    Full Text Available Road traffic information is the basis of road traffic management and control. Due to the special design of the sensor coil and ferromagnetic core, traffic survey system which uses micro ferromagnetic inductive coil vehicle detector, not only has the features of small size, simple installation and little road surface damage, but also has the advantages of output signal strength, simple signal processing circuit and obvious characteristics for output waveform corresponding vehicle feature. Based on the introduction of the sensor working principle, the construction of hardware and signal processing circuit for the traffic survey system is described in detail in the paper. Combined with the characteristics of the sensor output waveform, adaptive nearest neighbor clustering RBF neural network algorithm used to classify the vehicles is proposed and verified by experimental method. The result has a high vehicle classification rate and demonstrates the feasibility of the system.

    Accurate surveillance is critical for monitoring the epidemiology of emerging tobacco products in the United States, and survey science suggests that survey response format can impact prevalence estimates. We utilized data from the 2014 New Jersey Youth Tobacco Survey (n = 3,909) to compare estimates of the prevalence of 4 behaviors (ever hookah use, current hookah use, ever e-cigarette use, and current e-cigarette use) among New Jersey high school students, as assessed using "check-all-that-apply" questions, with estimates measured by means of "forced-choice" questions. Measurement discrepancies were apparent for all 4 outcomes, with the forced-choice questions yielding prevalence estimates approximately twice those of the check-all-that-apply questions, and agreement was fair to moderate. The sensitivity of the check-all-that-apply questions, treating the forced-choice format as the "gold standard," ranged from 38.1% (current hookah use) to 58.3% (ever e-cigarette use), indicating substantial false-negative rates. These findings highlight the impact of question response format on prevalence estimates of emerging tobacco products among youth and suggest that estimates generated by means of check-all-that-apply questions may be biased downward. Alternative survey designs should be considered to avoid check-all-that-apply response formats, and researchers should use caution when interpreting tobacco use data obtained from check-all-that-apply formats. © The Author(s) 2017.

    The authors conducted a survey examining (1) the current state of evidence-based medicine (EBM) curricula in US and Canadian medical schools and corresponding learning objectives, (2) medical educators' and librarians' participation in EBM training, and (3) barriers to EBM training. A survey instrument with thirty-four closed and open-ended questions was sent to curricular deans at US and Canadian medical schools. The survey sought information on enrollment and class size; EBM learning objectives, curricular activities, and assessment approaches by year of training; EBM faculty; EBM tools; barriers to implementing EBM curricula and possible ways to overcome them; and innovative approaches to EBM education. Both qualitative and quantitative methods were used for data analysis. Measurable learning objectives were categorized using Bloom's taxonomy. One hundred fifteen medical schools (77.2%) responded. Over half (53%) of the 900 reported learning objectives were measurable. Knowledge application was the predominant category from Bloom's categories. Most schools integrated EBM into other curricular activities; activities and formal assessment decreased significantly with advanced training. EBM faculty consisted primarily of clinicians, followed by basic scientists and librarians. Various EBM tools were used, with PubMed and the Cochrane database most frequently cited. Lack of time in curricula was rated the most significant barrier. National agreement on required EBM competencies was an extremely helpful factor. Few schools shared innovative approaches. Schools need help in overcoming barriers related to EBM curriculum development, implementation, and assessment. Findings can provide a starting point for discussion to develop a standardized competency framework.

    The increase in natural and man-made disasters occurring worldwide places Emergency Medicine (EM) physicians at the forefront of responding to these crises. Despite the growing interest in Disaster Medicine, it is unclear if resident training has been able to include these educational goals. Hypothesis This study surveys EM residencies in the United States to assess the level of education in Disaster Medicine, to identify competencies least and most addressed, and to highlight effective educational models already in place. The authors distributed an online survey of multiple-choice and free-response questions to EM residency Program Directors in the United States between February 7 and September 24, 2014. Questions assessed residency background and details on specific Disaster Medicine competencies addressed during training. Out of 183 programs, 75 (41%) responded to the survey and completed all required questions. Almost all programs reported having some level of Disaster Medicine training in their residency. The most common Disaster Medicine educational competencies taught were patient triage and decontamination. The least commonly taught competencies were volunteer management, working with response teams, and special needs populations. The most commonly identified methods to teach Disaster Medicine were drills and lectures/seminars. There are a variety of educational tools used to teach Disaster Medicine in EM residencies today, with a larger focus on the use of lectures and hospital drills. There is no indication of a uniform educational approach across all residencies. The results of this survey demonstrate an opportunity for the creation of a standardized model for resident education in Disaster Medicine.

    Little is known about the financial burden experienced by patients receiving radiation therapy. Furthermore, currently, no financial toxicity screening tools have been validated for use in radiation oncology. Physician surveys were used to gauge provider understanding of treatment costs and their willingness to adopt the use of financial toxicity screening tools. Post-treatment patient surveys were used to investigate the covariates of treatment-induced financial risk. Of the 210 radiation oncologists who completed our survey, 53% reported being "very concerned" with treatment-related costs negatively affecting their patients, and 80% believed that a financial toxicity screening tool would be useful in practice. An analysis of patient surveys using logistic regression found age and cancer site to be the most important variables associated with financial toxicity. Thirty-four patients (22%) experienced financial toxicity related to treatment. The financial toxicities experienced were loss of job (28%), loss of income (24%), difficulty paying their rent or mortgage (20%), difficulty paying for transportation (15%), and difficulty paying for meals (13%). Financial toxicity is an important measure for patients and providers and is experienced by approximately one quarter of patients. Further studies to improve models to predict financial toxicity and how financial toxicity is related to patient outcomes and quality of life are warranted. Copyright © 2018 Elsevier Inc.

    The region of Vinaninkarena located in central Madagascar (47°02'40"E, 19°57'17"S), is known to be a high natural radioactive area. Uranium ore was extracted in this region during the 1950s and the early 1960s. In the mid-1960s, mining activities were stopped and the site abandoned. In the meantime, the region, which used to be without any inhabitants, has recently been occupied by new settlers with presumed increase in exposure of the local population to natural ionizing radiation. In order to assess radiological risk, a survey to assess the soil natural radioactivity background was conducted during the year 2004. This study was implemented in the frame of the FADES Project SP99v1b_21 entitled: Assessment of the environmental pollution by multidisciplinary approach, and the International Atomic Energy Agency Technical Cooperation Project MAG 7002 entitled: Effects of air and water pollution on human health. Global Positioning System (GPS) was used to determine the geographical coordinates of the top soil samples (0-15cm) collected. The sampling was performed using a multi integrated scale approach to estimate the spatial variability of the parameters under investigation (U, Th and K) using geo-statistical approach. A total of 205 soil samples was collected in the study site (16 km2). After humidity correction, the samples were sealed in 100 cm3 cylindrical air-tight plastic containers and stored for more than 6 months to reach a secular equilibrium between parents and short-lived progeny (226Ra and progeny, 238U and 234Th). Measurements were performed using a high-resolution HPGe Gamma-detector with a 30% relative efficiency and an energy resolution of 1.8 keV at 1332.5 keV, allowing the determination of the uranium and thorium series and 40K. In case of secular equilibrium, a non-gamma-emitting radionuclide activity was deduced from its gamma emitting progeny. This was the case for 238U (from 234Th), 226Ra (from 214Pb and 214Bi) and 232Th (from 228Ac, 212Pb or

    Given the scarcity of mental health resources available for refugees in areas of conflict, it is imperative to investigate interventions that would be accepted by the refugees. In this study we surveyed 354 Syrian refugees using the HADStress screening tool and asked about their openness to referral to psychiatry and telepsychiatry. Of the surveyed sample, 41.8% had scores on HADStress that correlate to posttraumatic stress disorder. However, only 34% of the whole sample reported a perceived need to see a psychiatrist, and of those only 45% were open to telepsychiatry. Women, those who were bilingual, and those with positive HADStress status were less likely to accept telepsychiatry; however, this finding did not reach statistical significance. This study reports a partial acceptance of Syrian refugees for telepsychiatric services despite the high prevalence of psychological stress.

  2. Where’s Your Phone? A Survey of Where Women Aged 15-40 Carry Their Smartphone and Related Risk Perception: A Survey and Pilot Study

    Science.gov (United States)

    2017-01-01

    Smartphones are now owned by most young adults in many countries. Installed applications regularly update while the phone is in standby. If it is kept near the body, this can lead to considerably higher exposure to radiofrequency electromagnetic radiation than occurred without internet access. Very little is known about current smartphone carrying habits of young women. This survey used an online questionnaire to ask about smartphone location under several circumstances to inform the power calculation for a women’s health study. They were also asked about risk perceptions. Data was analysed using Pearson chi square. Three age categories were made: 15–20, 21–30, 31–40. Smartphones were generally kept on standby (96% by day, 83% at night). Of all participants, in the last week the most common locations of the phone when not in use or during passive use was off-body (86%), in the hand (58%), a skirt/trouser pocket (57%), or against the breast (15%). Pocket and near-the-breast storage were significant by age (χ215.04, p = 0.001 and χ210.96, p = 0.04, respectively), both positively influenced by the youngest group. The same influence lay in the association between holding the phone (χ211.082, p = 0.004) and pocket-storage (χ219.971, pperception of health risk (χ2 6.695, p = 0.035). Our findings can be used in the power calculation for a case-control study. PMID:28060844

    Emerging evidence indicates mobile technology-based strategies may improve access to secondary prevention and reduce risk factors in cardiac patients. However, little is known about cardiac patients' use of mobile technology, particularly for health reasons and whether the usage varies across patient demographics. This study aimed to describe cardiac patients' use of mobile technology and to determine variations between age groups after adjusting for education, employment, and confidence with using mobile technology. Cardiac patients eligible for attending cardiac rehabilitation were recruited from 9 hospital and community sites across metropolitan and rural settings in New South Wales, Australia. Participants completed a survey on the use of mobile technology devices, features used, confidence with using mobile technology, willingness and interest in learning, and health-related use. The sample (N=282) had a mean age of 66.5 (standard deviation [SD] 10.6) years, 71.9% (203/282) were male, and 79.0% (223/282) lived in a metropolitan area. The most common diagnoses were percutaneous coronary intervention (33.3%, 94/282) and myocardial infarction (22.7%, 64/282). The majority (91.1%, 257/282) used at least one type of technology device, 70.9% (200/282) used mobile technology (mobile phone/tablet), and 31.9% (90/282) used all types. Technology was used by 54.6% (154/282) for health purposes, most often to access information on health conditions (41.4%, 117/282) and medications (34.8%, 98/282). Age had an important independent association with the use of mobile technology after adjusting for education, employment, and confidence. The youngest group (mobile technology than the oldest (>69 years) age group (odds ratio [OR] 4.45, 95% CI 1.46-13.55), 5 times more likely to use mobile apps (OR 5.00, 95% CI 2.01-12.44), and 3 times more likely to use technology for health-related reasons (OR 3.31, 95% CI 1.34-8.18). Compared with the older group, the middle age group (56

    Cross-identifying complex radio sources with optical or infra red (IR) counterparts in surveys such as the Australia Telescope Large Area Survey (ATLAS) has traditionally been performed manually. However, with new surveys from the Australian Square Kilometre Array Pathfinder detecting many tens of millions of radio sources, such an approach is no longer feasible. This paper presents new software (LRPY - Likelihood Ratio in PYTHON) to automate the process of cross-identifying radio sources with catalogues at other wavelengths. LRPY implements the likelihood ratio (LR) technique with a modification to account for two galaxies contributing to a sole measured radio component. We demonstrate LRPY by applying it to ATLAS DR3 and a Spitzer-based multiwavelength fusion catalogue, identifying 3848 matched sources via our LR-based selection criteria. A subset of 1987 sources have flux density values for all IRAC bands which allow us to use criteria to distinguish between active galactic nuclei (AGNs) and star-forming galaxies (SFG). We find that 936 radio sources ( ≈ 47 per cent) meet both of the Lacy and Stern AGN selection criteria. Of the matched sources, 295 have spectroscopic redshifts and we examine the radio to IR flux ratio versus redshift, proposing an AGN selection criterion below the Elvis radio-loud AGN limit for this dataset. Taking the union of all three AGNs selection criteria we identify 956 as AGNs ( ≈ 48 per cent). From this dataset, we find a decreasing fraction of AGNs with lower radio flux densities consistent with other results in the literature.

    Music, to many of us, is an indispensable ingredient of life for some unknown reason. Recently, it has become a quite popular research target for a number of reasons. Like language, it is learned from childhood either passively or actively. Unlike language, it cannot convey any precisely defined meaning but nevertheless can move us and make us happy. Unlike language only a small percentage of people can become truely proficient even in listening. In this survey paper, we look at how music has attracted many researchers who are endeavoring to find out how music attracts so many people from professionals to laymen.

    Audiologists must be knowledgeable about the efficacy of aural habilitation practices because we are often the first professionals to inform parents about their child's hearing impairment. The purpose of this investigation was to document the status of graduates of one aural habilitation option; auditory-verbal. A consumer survey was completed by graduates from auditory-verbal programs in the United States and Canada. Graduates were queried regarding degree and etiology of hearing loss, age of onset, amplification, and educational and employment history, among other topics. Results indicated that the majority of the respondents were integrated into regular learning and living environments.

    Coronary heart disease (CHD) is a common and costly condition and is increasing at a higher rate among Asian Indians than among other ethnic groups. An understanding of how Asian Indians perceive their risk is important for health providers to develop culturally appropriate programs to raise awareness of the risk of CHD. The aim of this survey was to investigate the attribution of risk factors for CHD among the Asian Indian community in Australia. Asian Indian community leaders were recruited to provide their views of how their community perceived the risk of CHD. An online survey collected demographic data and information from the Illness Perception Questionnaire-Revised, which measures 6 domains of illness perception: timeline acute/chronic, consequences, emotional impact, personal control, treatment efficacy, and illness comprehension. An 84% response rate (n = 49) was achieved from Asian Indian community leaders. Heart disease and cancer were considered to be the illnesses of major concern. Participants indicated that people in their community perceived hereditary factors (90%), hypertension, stress or worry (84%), and aging (86%) as the major cause of their illnesses. Smoking, high blood pressure, and cholesterol were identified as being major risk factors for CHD. These data suggest that as well as strategies to address risk factors such as diet and exercise, stress management is an important issue to consider in developing community-based programs.

    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.

    The shortage of ophthalmologists is a major obstacle in the struggle of fighting preventable blindness in sub-Saharan Africa. However, to date reasons affecting migration of ophthalmologists have not been completely understood. Evaluation of reasons reported by ophthalmologists for staying in their current work setting/country, of potential reasons for migration as well as of effects of German-African partnerships. In the years 2009-2011 and 2013 participants of continuous medical education courses in Ethiopia, Cameroon and Kenya were interviewed using a standardized questionnaire. A total of 106 ophthalmologists participated in this survey. In the years 2009/2010 participants were mainly board certified ophthalmologists, while the 2011/2013 surveys were answered mainly by residents. The main reasons for staying in their current region/country were good working conditions, commitment to help/patriotism, possibility of further training, good income and familial ties. Professional development elsewhere and better income abroad were named as the main reasons for considering migration followed by better technical equipment elsewhere and insecurity in the home country. Good working conditions and the possibility of further training were named as the top reasons for staying in the current region/country apart from commitment to help and familial ties. Therefore, international cooperation programs aiming at improving training of ophthalmologists and establishing an ophthalmic infrastructure may have a role in promoting ophthalmic care in Africa.

    Large volume, actively shielded Phoswich detector configurations were investigated for application in airborne radiometric survey systems in order to increase the sensitivity to ground-level potassium, uranium, and thorium compared to conventional NaI detectors of similar sizes. One Phoswich configuration was fabricated and flight tested. The flight measurements with the Phoswich detector and a conventional NaI detector utilized the Bendix Field Engineering Corporation - US Department of Energy/Grand Junction Office Walker Field Aerial Radiometric Survey Calibration Facility, the DOE dynamic test range, and a region in the southwest portion of the Lubbock, Texas, Quadrangle. The tests demonstrated that the Phoswich detector can function in an operational environment and does provide greater sensitivity to ground-level potassium, uranium, and thorium concentration than the conventional NaI detector. The multicrystal configuration for the Phoswich detector provided the capability to simultaneously measure the atmospheric radon background without the need of heavy lead shields. The flight tests indicated that the Phoswich detector has directional discrimination capability not available with conventional NaI detector systems. This directional capability can be used to distinguish the location, relative to the aircraft, of localized strong sources of radiation

    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.

    Ground Penetrating Radar (GPR) systems are well assessed non-invasive diagnostic tools capable of providing high resolution images of the inner structure of the probed spatial region. Owing to this capability, GPR systems are nowadays more and more considered in the frame of civil engineering surveys since they may give information on constructive details as well as on the aging and risk factors affecting the healthiness of an infrastructure. In this frame, accurate, reliable and easily interpretable images of the probed scenarios are mandatory in order to support the management of maintenance works and assure the safety of structures. Such a requirement motivates the use of different and sophisticated data processing approaches in order to compare more than one image of the same scene, thus improving the reliability and objectiveness of the GPR survey results. Among GPR data processing procedures, Microwave Tomography approaches based on the Born approximation face the imaging as the solution of a linear inverse problem, which is solved by using the Truncated Singular Value Decomposition as a regularized inversion scheme [1]. So far, an approach exploiting a 2D scalar model of the scattering phenomenon have been adopted to process GPR data gathered along a single scan. In this case, 3D images are obtained by interpolating 2D reconstructions (this is referred commonly as pseudo 3D imaging). Such an imaging approach have provided valuable results in several real cases dealing with not only surveys for civil engineering but also archeological prospection, subservice monitoring, security surveys and so on [1-4]. These encouraging results have motivated the development of a full 3D Microwave Tomography approach capable of accounting for the vectorial nature of the wave propagation. The reconstruction capabilities of this novel approach have been assessed mainly against experimental data collected in laboratory controlled conditions. The obtained results corroborate

    Objective. To describe the design of the SABE Colombia study. The major health study of the old people in Latin America and the Caribbean (LAC) is the Survey on Health, Well-Being, and Aging in LAC, SABE (from initials in Spanish: SAlud, Bienestar & Envejecimiento). Methods. The SABE Colombia is a population-based cross-sectional study on health, aging, and well-being of elderly individuals aged at least 60 years focusing attention on social determinants of health inequities. Methods and design were similar to original LAC SABE. The total sample size of the study at the urban and rural research sites (244 municipalities) was 23.694 elderly Colombians representative of the total population. The study had three components: (1) a questionnaire covering active aging determinants including anthropometry, blood pressure measurement, physical function, and biochemical and hematological measures; (2) a subsample survey among family caregivers; (3) a qualitative study with gender and cultural perspectives of quality of life to understand different dimensions of people meanings. Conclusions. The SABE Colombia is a comprehensive, multidisciplinary study of the elderly with respect to active aging determinants. The results of this study are intended to inform public policies aimed at tackling health inequalities for the aging society in Colombia. PMID:27956896

    Full Text Available Aims. The aim of this study was to examine the prevalence of depressive symptoms and their related factors in Japan. The results were analyzed to identify the relationship between high scores on the CES-D, sociodemographic status, and employment-related variables. Methods. Employees in Akita prefecture completed the Center for Epidemiologic Studies Depression Scale (CES-D during a survey period between November and December 2010. The cutoff point for the CES-D scores was 16 or above (high scorers. Results. Data from 1,476 employees indicated that 44.2% had high scores on the CES-D. Sociodemographic and occupation-related factors associated with a high risk of depression were being female, young age, fewer hours of sleep on weekdays, and working over 8 hours per day, whereas drinking alcohol one to two days per week, albeit only in men, was significantly associated with a low risk of depression. The present results were consistent with the results of a previous survey completed in 2007; however, the present results regarding job categories and smoking behavior were not significantly associated with depression and thus were inconsistent with the 2007 survey data. Conclusions. These results can be useful as benchmark values for the CES-D and might help predict depressive disorders.

    Full Text Available Response rates to the academic surveys used in quantitative research are decreasing and have been for several decades among both individuals and organizations. Given this trend, providing doctoral students an opportunity to complete their dissertations in a timely and cost effective manner may necessitate identifying more innovative and relevant ways to collect data while maintaining appropriate research standards and rigor. The case of a research study is presented which describes the data collection process used to survey a hard-to-reach population. It details the use of social media, in this case LinkedIn, to facilitate the distribution of the web-based survey. A roadmap to illustrate how this data collection process unfolded is presented, as well as several “lessons learned” during this journey. An explanation of the considerations that impacted the sampling design is provided. The goal of this case study is to provide researchers, including doctoral students, with realistic expectations and an awareness of the benefits and risks associated with the use of this method of data collection.

    A questionnaire survey was performed to investigate the possible presence of self-selection bias in 18 F-fluorodeoxyglucose (FDG) positron emission tomography (PET) cancer screening (PET cancer screening). Responders to the questionnaires survey consisted of 80 healthy persons, who answered whether they undergo PET cancer screening, health consciousness, age, sex, and smoking history. The univariate and multivariate analyses on the four parameters were performed between the responders who were to undergo PET cancer screening and the responders who were not. Statistically significant difference was found in health consciousness between the above-mentioned two groups by both univariate and multivariate analysis with the odds ratio of 2.088. The study indicated that self-selection bias should exist in PET cancer screening. (author)

    The NASA Orbital Debris Program Office (ODPO) recently commissioned the Meter Class Autonomous Telescope (MCAT) on Ascension Island with the primary goal of obtaining population statistics of the geosynchronous (GEO) orbital debris environment. To help facilitate this, studies have been conducted using MCAT's known and projected capabilities to estimate the accuracy and timeliness in which it can survey the GEO environment. A simulated GEO debris population is created and sampled at various cadences and run through the Constrained Admissible Region Multi Hypotheses Filter (CAR-MHF). The orbits computed from the results are then compared to the simulated data to assess MCAT's ability to determine accurately the orbits of debris at various sample rates. Additionally, estimates of the rate at which MCAT will be able produce a complete GEO survey are presented using collected weather data and the proposed observation data collection cadence. The specific methods and results are presented here.

    Transdermal alcohol monitoring technology allows for new research on alcohol use disorders. This study assessed feasibility, acceptability, and adherence with this technology in the context of two clinical research trials. Participants were the first 100 community-based alcohol treatment outpatients enrolled in randomized studies that monitored drinking with the secure continuous remote alcohol monitor (SCRAMx ® ) for 12 weeks. Study 1 participants were randomized to usual care (n=36) or usual care with contingency management incentives for treatment attendance (CM-Att; n=30). Study 2 participants were randomized to usual care (n=17) or usual care with CM for each day of no drinking per SCRAMx (CM-Abst; n=17). After 12 weeks, participants completed a survey about the bracelet. Nine percent of individuals screened (54 of 595) declined participation because of the bracelet. Of participants, 84% provided 12weeks of data, and 96% of bracelets were returned fully intact. Ninety-four equipment tampers occurred, affecting 2% of monitoring days; 56% (67) of tampers coincided with detected drinking. Common concerns reported by participants were skin marks (58%), irritation (54%), and interfered with clothing choices (51%), but severity ratings were generally mild (60%-94%). Eighty-one percent of participants reported that the bracelet helped them reduce drinking, and 75% indicated that they would wear it for longer. A common suggestion for improvement was to reduce the size of the bracelet. Results support the viability of transdermal monitoring in voluntary substance abuse treatment participants for an extended duration. Issues to consider for future applications of this technology are discussed. Copyright © 2017 Elsevier B.V. All rights reserved.

    2005-01-01

    Background Members of the Deaf community face communication barriers to accessing health information. To resolve these inequalities, educational programs must be designed in the appropriate format and language to meet their needs. Methods Deaf men (102) were surveyed before, immediately following, and two months after viewing a 52-minute prostate and testicular cancer video in American Sign Language (ASL) with open text captioning and voice overlay. To provide the Deaf community with information equivalent to that available to the hearing community, the video addressed two cancer topics in depth. While the inclusion of two cancer topics lengthened the video, it was anticipated to reduce redundancy and encourage men of diverse ages to learn in a supportive, culturally aligned environment while also covering more topics within the partnership's limited budget. Survey data were analyzed to evaluate the video's impact on viewers' pre- and post-intervention understanding of prostate and testicular cancers, as well as respondents' satisfaction with the video, exposure to and use of early detection services, and sources of cancer information. Results From baseline to immediately post-intervention, participants' overall knowledge increased significantly, and this gain was maintained at the two-month follow-up. Men of diverse ages were successfully recruited, and this worked effectively as a support group. However, combining two complex cancer topics, in depth, in one video appeared to make it more difficult for participants to retain as many relevant details specific to each cancer. Participants related that there was so much information that they would need to watch the video more than once to understand each topic fully. When surveyed about their best sources of health information, participants ranked doctors first and showed a preference for active rather than passive methods of learning. Conclusion After viewing this ASL video, participants showed significant increases

    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 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 depression threshold and 75 (4.1%) pilots

  6. The Use of Religious Coping Methods in a Secular Society: A Survey Study Among Cancer Patients in Sweden.

    2017-07-01

    In the present article, based on results from a survey study in Sweden among 2,355 cancer patients, the role of religion in coping is discussed. The survey study, in turn, was based on earlier findings from a qualitative study of cancer patients in Sweden. The purpose of the present survey study was to determine to what extent results obtained in the qualitative study can be applied to a wider population of cancer patients in Sweden. The present study shows that use of religious coping methods is infrequent among cancer patients in Sweden. Besides the two methods that are ranked in 12th and 13th place, that is, in the middle (Listening to religious music and Praying to God to make things better), the other religious coping methods receive the lowest rankings, showing how nonsignificant such methods are in coping with cancer in Sweden. However, the question of who turns to God and who is self-reliant in a critical situation is too complicated to be resolved solely in terms of the strength of individuals' religious commitments. In addition to background and situational factors, the culture in which the individual was socialized is an important factor. Regarding the influence of background variables, the present results show that gender, age , and area of upbringing played an important role in almost all of the religious coping methods our respondents used. In general, people in the oldest age-group, women, and people raised in places with 20,000 or fewer residents had a higher average use of religious coping methods than did younger people, men, and those raised in larger towns.

    Full Text Available Abstract Background We aimed to establish levels of consumer involvement in randomised controlled trials (RCTs, meta-analyses and other studies carried out by the UK Medical Research Council (MRC Clinical Trials Unit across the range of research programs, predominantly in cancer and HIV. Methods Staff responsible for studies that were included in a Unit Progress Report (MRC CTU, April 2009 were asked to complete a semi-structured questionnaire survey regarding consumer involvement. This was defined as active involvement of consumers as partners in the research process and not as subjects of that research. The electronic questionnaires combined open and closed questions, intended to capture quantitative and qualitative information on whether studies had involved consumers; types of activities undertaken; recruitment and support; advantages and disadvantages of involvement and its perceived impact on aspects of the research. Results Between October 2009 and April 2010, 138 completed questionnaires (86% were returned. Studies had been conducted over a 20 year period from 1989, and around half were in cancer; 30% in HIV and 20% were in other disease areas including arthritis, tuberculosis and blood transfusion medicine. Forty-three studies (31% had some consumer involvement, most commonly as members of trial management groups (TMG [88%]. A number of positive impacts on both the research and the researcher were identified. Researchers generally felt involvement was worthwhile and some felt that consumer involvement had improved the credibility of the research. Benefits in design and quality, trial recruitment, dissemination and decision making were also perceived. Researchers felt they learned from consumer involvement, albeit that there were some barriers. Conclusions Whilst most researchers identified benefits of involving consumers, most of studies included in the survey had no involvement. Information from this survey will inform the development

    2014-03-01

    Full Text Available The aim of the paper is to evaluate the perspectives of development of organic food supply in Poland. The work contains the results of the nationwide survey which was carried out among conventional farms’ owners. It was evaluated that – according to farmers’ declaration – organic farms number can be equal to 6.8-24.2% of all Polish farms. The main incentives influencing conversion into organic farming methods are health and environment care, satisfaction from work and agri-environmental subsidies. The main identified barriers are limited sales possibilities, low profitability of production, high labour intensity, high production cost, and low yield. In a long run the development of organic market could be stimulated by the increase of demand. In the middle time period, there is a need for the increase of subsidies rates which should be combined with the improvement of certification and control system.

    Full Text Available Energy efficiency has become one of the top design criteria for current computing systems. The dynamic voltage and frequency scaling (DVFS has been widely adopted by laptop computers, servers, and mobile devices to conserve energy, while the GPU DVFS is still at a certain early age. This paper aims at exploring the impact of GPU DVFS on the application performance and power consumption, and furthermore, on energy conservation. We survey the state-of-the-art GPU DVFS characterizations, and then summarize recent research works on GPU power and performance models. We also conduct real GPU DVFS experiments on NVIDIA Fermi and Maxwell GPUs. According to our experimental results, GPU DVFS has significant potential for energy saving. The effect of scaling core voltage/frequency and memory voltage/frequency depends on not only the GPU architectures, but also the characteristic of GPU applications.

    Allaire, P.E.; Barrett, L.E.

    1982-06-01

    This report presents an up-to-date literature survey, examples of calculations of seal forces or other pump properties, and recommendations for future work pertaining to primary coolant pumps and primary recirculating pumps in the nuclear power industry. Five main areas are covered: pump impeller forces, fluid annuli, bearings, seals, and rotor calculations. The main conclusion is that forces in pump impellers is perhaps the least well understood area, seals have had some good design work done on them recently, fluid annuli effects are being discussed in the literature, bearing designs are fairly well known, and rotor calculations have been discussed widely in the literature. It should be noted, however, that usually the literature in a given area is not applied to pumps in nuclear power stations. The most immediate need for a combined theoretical and experimental design capability exists in mechanical face seals

    Kemmelmeier, Markus

    2016-12-01

    This paper introduces the special section "Cultural differences in questionnaire responding" and discusses central topics in the research on response biases in cross-cultural survey research. Based on current conceptions of acquiescent, extreme, and socially desirable responding, the author considers current data on the correlated nature of response biases and the conditions under which different response styles they emerge. Based on evidence relating different response styles to the cultural dimension of individualism-collectivism, the paper explores how research presented as part of this special section might help resolves some tensions in this literature. The paper concludes by arguing that response styles should not be treated merely as measurement error, but as cultural behaviors in themselves. © 2016 International Union of Psychological Science.

    In this work, we perform a statistical investigation towards 50 high-mass clumps using data from the Bolocam Galactic Plane Survey (BGPS) and Millimetre Astronomy Legacy Team 90-GHz survey (MALT90). Eleven dense molecular lines (N2H+(1–0), HNC(1–0), HCO+(1–0), HCN(1–0), HN13C(1–0), H13CO+(1–0), C2H(1–0), HC3N(10–9), SiO(2–1), 13CS(2–1)and HNCO(44,0 ‑ 30,3)) are detected. N2H+ and HNC are shown to be good tracers for clumps in various evolutionary stages since they are detected in all the fields. The detection rates of N-bearing molecules decrease as the clumps evolve, but those of O-bearing species increase with evolution. Furthermore, the abundance ratios [N2H+]/[HCO+] and log([HC3N]/[HCO+]) decline with log([HCO+]) as two linear functions, respectively. This suggests that N2H+ and HC3N transform to HCO+ as the clumps evolve. We also find that C2H is the most abundant molecule with an order of magnitude 10‑8. In addition, three new infall candidates, G010.214–00.324, G011.121–00.128 and G012.215–00.118(a), are discovered to have large-scale infall motions and infall rates with an order of magnitude 10‑3 M ⊙ yr‑1.

    2006-10-01

    To assess the frequency of reported mobbing and the association among mobbing, working environment factors, stress, health outcome, personality type, and work ability index in a sample of physicians in Bosnia and Herzegovina. We conducted a questionnaire survey using a validated self-reported questionnaire among 511 physicians in national health sector of Bosnia and Herzegovina. The questions covered five major categories of mobbing behavior. Characteristics of the work, perceived work environment and its effects, stress, health, and satisfaction with work and life were assessed by the standardized abridged form of Occupational Stress Questionnaire (OSQ). A standardized questionnaire Work Ability Index (WAI) was used to determine the relation between mobbing and work ability. Of 511 surveyed physicians, 387 (76%) physicians self-reported mobbing behavior in the working environment and 136 (26%) was exposed to persistent mobbing. More than a half of the physicians experienced threats to their professional status and almost a half felt isolated. Logistic regression analysis showed that lack of motivation, loss of self-esteem, loss of confidence, fatigue, and depressiveness were significantly associated with lack of support from colleagues. Intention to leave work was associated with lack of support from colleagues (OR 2.3, 95% CI, 1.065-3.535; t =4.296, P =0.003) and lack of support from superiors (OR 1.526, 95% CI, 0.976-2.076; t =5.753; P =0.001). Isolation or exclusion and threats to professional status were predictors for mental health symptoms. Persistent mobbing experience was a significant predictor for sick leave. Exposure to persistent threat to professional status and isolation or exclusion as forms of mobbing are associated with mental health disturbances and lack of self-esteem and confidence. Setting up a system of support for physicians exposed to mobbing may have important benefits.

    Smartphones are now owned by most young adults in many countries. Installed applications regularly update while the phone is in standby. If it is kept near the body, this can lead to considerably higher exposure to radiofrequency electromagnetic radiation than occurred without internet access. Very little is known about current smartphone carrying habits of young women. This survey used an online questionnaire to ask about smartphone location under several circumstances to inform the power calculation for a women's health study. They were also asked about risk perceptions. Data was analysed using Pearson chi square. Three age categories were made: 15-20, 21-30, 31-40. Smartphones were generally kept on standby (96% by day, 83% at night). Of all participants, in the last week the most common locations of the phone when not in use or during passive use was off-body (86%), in the hand (58%), a skirt/trouser pocket (57%), or against the breast (15%). Pocket and near-the-breast storage were significant by age (χ215.04, p = 0.001 and χ210.96, p = 0.04, respectively), both positively influenced by the youngest group. The same influence lay in the association between holding the phone (χ211.082, p = 0.004) and pocket-storage (χ219.971, p<0.001) during passive use. For calls, 36.5% solely used the phone against the head. More than half kept the phone 20-50 cms from their head at night (53%), while 13% kept it closer than 20 cms. Many (36%) thought RF-EMR exposure was related to health problems while 16% did not. There was no relationship between thinking RF-EMR exposure causes health problems in general and carrying the phone against the upper or lower body (p = 0.69 and p = 0.212, respectively). However, calls with the phone against the head were positively related to perception of health risk (χ2 6.695, p = 0.035). Our findings can be used in the power calculation for a case-control study.

    The Scottish Mental Survey of 1932 (SMS1932) recorded mental ability test scores for nearly all of the age group of children born in 1921 and at school in Scotland on 1st June 1932. The Collaborative and Renfrew/Paisley studies, two of the Midspan studies, obtained health and social data by questionnaire and a physical examination in the 1970s. Some Midspan participants were born in 1921 and may have taken part in the SMS1932, so might have mental ability data available from childhood. The 19...

    The study examined the influence of IQ at age 11 years on marital status by mid-adulthood. The combined databases of the Scottish Mental Survey 1932 and the Midspan studies provided data from 883 subjects. With regard to IQ at age 11, there was an interaction between sex and marital status by mid-adulthood (p = 0.0001). Women who had ever-married achieved mean lower childhood IQ scores than women who had never-married (p < 0.001). Conversely, there was a trend for men who had ever-mar...

    The purpose of this study was to identify training topics and distance education technologies preferred by U.S. Fish and Wildlife Service employees. This study was conducted on behalf of the National Conservation Training Center to support their distance education strategy planning and implementation. When selecting survey recipients, we focused on employees in positions involving conservation and environmental education and outreach programming. We conducted the study in two phases. First, we surveyed 72 employees to identify useful training topics. The response rate was 61 percent; respondents were from all regions and included supervisors and nonsupervisors. Five topics for training were identified: creating and maintaining partnerships (partnerships), technology, program planning and development (program planning), outreach methods to engage the community (outreach methods), and evaluation methods. In the second phase, we surveyed 1,488 employees to assess preferences for training among the five topics identified in the first survey and preferences among six distance education technologies: satellite television, video conferencing, audio conferencing, computer mediated training, written resources, and audio resources. Two types of instructor-led training were included on the survey to compare to the technology options. Respondents were asked what types of information, such as basic facts or problem solving skills, were needed for each of the five topics. The adjusted response rate was 64 percent; respondents were from all regions and included supervisors and nonsupervisors. The results indicated clear preferences among respondents for certain training topics and technologies. All five training topics were valued, but the topics of partnerships and technology were given equal value and were valued more than the other three topics. Respondents indicated a desire for training on the topics of partnerships, technology, program planning, and outreach methods. For

    Pesticide use patterns are essential inputs into human pesticide exposure models. Currently, data included for modeling purposes have mostly been collected in cross-sectional surveys. However, it is questionable whether responses to one-time surveys are representative of pesticide use over longer periods, which is needed for assessment of health impact. This study was designed to evaluate population-wide temporal variations and within-household variations in reported residential pesticide use patterns and to compare alternative pesticide data collection methods - web surveys versus telephone interviews. A total of 481 households in Northern California provided up to 3 annual telephone interviews on residential pesticide use; 182 of these households provided up to 6 quarterly web surveys that covered the same topics for some of the same time periods. Information on frequency and areas of application were collected for outdoor and indoor sprays, indoor foggers, professional applications, and behind-the-neck treatments for pets. Population-wide temporal variation and within-household consistency were examined both within telephone surveys and within web surveys, and quantified using Generalized Estimating Equations and Mixed Effect Modeling. Reporting between the two methods, the telephone survey and the web survey, was also compared. Use prevalence of outdoor sprays across the population reported in both the annual telephone surveys and the quarterly web surveys decreased over time, as did behind-the-neck treatment of pets reported in the quarterly web survey. Similarly, frequencies of use of these products decreased in the quarterly web surveys. Indoor sprays showed no statistically significant population-wide temporal variation in either survey. Intraclass correlation coefficients indicated consistent use within a household for behind-the-neck treatment on pets and outdoor sprays but great variability for the use of indoor sprays. Indoor sprays were most

  7. Integrated geophysical survey for the geological structural and hydrogeothermal study of the North-western Gargano promontory (Southern Italy

    Full Text Available A multimethodological geophysical survey was performed in the north-western part of the Gargano promontory to study the geological structural setting and the underground fluid flow characteristics. The area has a complex tectonics with some magmatic outcrops and shallow low-enthalpy waters. Electrical, seismic reflection, gravimetric and magnetic surveys were carried out to reconstruct the geological structures; and in order to delineate the hydrogeothermal characteristics of the area, the self-potential survey was mainly used. Moreover magnetic and self-potential measurements were also performed in the Lesina lake. The joint three-dimensional interpretation of the geophysical data disclosed a large horst and graben structure covering a large part of the area. In the central part of the horst a large ramified volcanic body was modelled. The models show some intrusions rising from it to or near to the surface. The main structures are well deep-seated in the Crust and along them deep warm fluids rise as the SP data interpretation indicates.

    This site study plan describes seismic reflection surveys to run north-south and east-west across the Deaf Smith County site, and intersecting near the Engineering Design Boreholes (EDBH). Both conventional and shallow high-resolution surveys will be run. The field program has been designed to acquire subsurface geologic and stratigraphic data to address information/data needs resulting from Federal and State regulations and Repository program requirements. The data acquired by the conventional surveys will be common-depth- point, seismic reflection data optimized for reflection events that indicate geologic structure near the repository horizon. The data will also resolve the basement structure and shallow reflection events up to about the top of the evaporite sequence. Field acquisition includes a testing phase to check/select parameters and a production phase. The field data will be subjected immediately to conventional data processing and interpretation to determine if there are any anamolous structural for stratigraphic conditions that could affect the choice of the EDBH sites. After the EDBH's have been drilled and logged, including vertical seismic profiling, the data will be reprocessed and reinterpreted for detailed structural and stratigraphic information to guide shaft development. The shallow high-resulition seismic reflection lines will be run along the same alignments, but the lines will be shorter and limited to immediate vicinity of the EDBH sites. These lines are planned to detect faults or thick channel sands that may be present at the EDBH sites. 23 refs. , 7 figs., 5 tabs

    Effective exercise interventions are needed to improve quality of life and decrease the impact of chronic disease. Researchers suggest males have been underrepresented in exercise intervention studies, resulting in less understanding of their exercise practices. Findings from preference survey methods suggest reasonable association between preference and behavior. The purpose of the research described in this article was to use factorial survey, a preference method, to identify the characteristics of exercise interventions most likely to appeal to male participants, so preferences might be incorporated into future intervention research. The research was guided by the framework of Bandura's social cognitive theory, such that variations in individual, environmental, and behavioral factors were incorporated into vignettes. Participants included 53 adult male nonadministrative staff and contract employees at a public university in the Southeastern United States, who each scored 8 vignettes resulting in 423 observations. Multilevel models were used to assess the influence of the factors. Participants scored vignettes that included exercising with a single partner, playing basketball, and exercising in the evening higher than vignettes with other options. Qualitative analysis of an open response item identified additional alternatives in group size, participant desire for coaching support, and interest in programs that incorporate a range of activity alternatives. Findings from this research were consistent with elements of social cognitive theory as applied to health promotion. Factorial surveys potentially provide a resource effective means of identifying participants' preferences for use when planning interventions. The addition of a single qualitative item helped clarify and expand findings from statistical analysis.

    Minimally invasive lateral interbody fusion (MIS-LIF) has become a popular less invasive treatment option for degenerative spinal disease, deformity, and trauma. While MIS-LIF offers several advantages over traditional anterior and posterior approaches, the procedure is not without risk. The purpose of this study was to evaluate the incidence of visceral, vascular, and wound complications following MIS-LIF performed by experienced surgeons. A survey was conducted by experienced (more than 100 case experience) MIS-LIF surgeons active in the society of lateral access surgery (SOLAS) to collect data on wound infections and visceral and vascular injuries. Of 77 spine surgeons surveyed, 40 (52 %) responded, including 25 (63 %) orthopedic surgeons and 15 (38 %) neurosurgeons, with 20 % practicing at an academic institution and 80 % in community practice. Between 2003 and 2013, 13,004 patients were treated with MIS-LIF by the 40 surgeons who responded to the survey. Of those patients, 0.08 % experienced a visceral complication (bowel injury), 0.10 % experienced a vascular injury, 0.27 % experienced a superficial wound infection, and 0.14 % experienced a deep wound infection. The incidence of surgical site infections and vascular and visceral complications following MIS-LIF in this large series was low and compared favorably with rates for alternative interbody fusion approaches. Although technically demanding, MIS-LIF is a reproducible approach for interbody fusion with a low risk of vascular and visceral complications and infections.

    The present article illustrates how the National Household Education Surveys (NHES; U.S. Department of Education, 2009) database might be used to address questions of relevance to researchers who are concerned with literacy development among young children. Following a general description of the NHES database, a study is provided that examines the extent to which parent-reported home literacy activities and child emergent literacy skills differ for children with (a) developmental disabilities versus those who are developing typically, (b) single disability versus multiple disabilities, and (c) speech-language disability only versus other types of disabilities. Four hundred and seventy-eight preschool-age children with disabilities and a typically developing matched sample (based on parent report) were identified in the 2005 administration of the Early Childhood Program Participation (ECPP) Survey in the NHES database. Parent responses to survey items were then compared between groups. After controlling for age and socioeconomic status, no significant differences were found in the frequency of home literacy activities for children with and without disabilities. Parents reported higher levels of emergent literacy skills for typically developing children relative to children with disabilities. These findings suggest the importance of considering the home literacy experiences and emergent literacy skills of young children with disabilities when making clinical recommendations.

    The International Network of Obstetric Survey Systems (INOSS) is a multi-country collaboration formed to facilitate studies of uncommon and severe complications of pregnancy and childbirth. Collaborations such as INOSS offer many benefits in the study of rare complications. The use of uniform case definitions, common datasets, specifically collected detailed data and prospectively agreed comparative and combined analyses all add to the validity of studies and their utility to guide policy and clinical practice and hence improve the quality of care. Such multi-national collaborations allow for the conduct of robust studies less subject to many of the biases attributed to typical observational studies. For very rare conditions such collaborations may provide the only route to providing high quality evidence to guide practice. Clinicians and researchers conducting studies into rare and severe complications should consider working through a network such as INOSS to maximize the value of their research. © 2013 Nordic Federation of Societies of Obstetrics and Gynecology.

    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.

    2009-08-01

    Full Text Available This article focuses on surveys of first-year language learners studying 19 different languages at two large East Coast Universities. The survey included questions about why students decided to study these languages, including career plans, study abroad, interest in liter-ature and culture, desire to communicate with speakers of the lan-guage, desire to speak with family members, building on previous language skills, and love of languages in general. Results were broken down by language and by language types, such as whether the lan-guages were commonly taught in the United States, how the lan-guages are politicized in the current historical context, and how the languages intersect with historical and geographic trends in immigra-tion and immigration policy. This article examines in particular the presence of heritage language learners in these language classrooms, the varying reasons that students choose to study these languages, and students’ prior attainment and exposure to the language. The pa-per discusses the political, historical, and social contexts of language study in the United States and the associated implications for effec-tive language recruitment and effective language program design.

    Human papillomavirus (HPV), a sexually transmitted infection, can cause anogenital warts and a number of cancers. To prevent morbidity and mortality, three vaccines have been licensed and are recommended by Canada's National Advisory Committee on Immunisation (for girls since 2007 and boys since 2012). Nevertheless, HPV vaccine coverage in Canada remains suboptimal in many regions. This study will be the first to concurrently examine the correlates of HPV vaccine decision-making in parents of school-aged girls and boys and evaluate changes in parental knowledge, attitudes and behaviours over time. Using a national, online survey utilising theoretically driven constructs and validated measures, this study will identify HPV vaccine coverage rates and correlates of vaccine decision-making in Canada at two time points (August-September 2016 and June-July 2017). 4606 participants will be recruited to participate in an online survey through a market research and polling firm using email invitations. Data cleaning methods will identify inattentive or unmotivated participants. The study received research ethics board approval from the Research Review Office, Integrated Health and Social Services University Network for West-Central Montreal (CODIM-FLP-16-219). The study will adopt a multimodal approach to disseminate the study's findings to researchers, clinicians, cancer and immunisation organisations and the public in Canada and internationally. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

  16. Hydrogeochemical and stream-sediment survey (NURE). Preliminary report on the Smoke Creek Desert Basin pilot study (Nevada)

    International Nuclear Information System (INIS)

    1976-01-01

    The Lawrence Livermore Laboratory (LLL) is conducting a hydrogeochemical and stream-sediment survey in the seven western states as part of ERDA's National Uranium Resources Evaluation (NURE) Program. The objective of this survey is to develop a geochemical data base for use by the private sector to locate regions of anomalous uranium content. Prior to wide area coverage, several pilot studies are being undertaken to develop and evaluate sampling and analytical techniques. The second through fifth of these studies were conducted in four playa basins in Nevada, selected to represent different regional geology and uranium occurrence. This study in the Smoke Creek Desert Basin, characterizes igneous surface geology with known uranium occurrences. The Smoke Creek Desert Basin is the largest of the four playa basins and contains an areaof about 2700 square kilometers (1003 square miles). The basin is bordered on the east by the Fox Hills and on the north and east by the Granite Ranges which are characterized by granite, pegmatites, and Tertiary rocks very similar to the lithology of the Winnemucca Basin boundary ranges (study UCID-16911-P-2). On the west the Desert is bordered by an area of extensive basalt flow. There is no known uranium occurrence in the area, and metallization of any kind is scarce. This study is applicable to the western igneous portion of the Basin and Range Province which includes southeastern Oregon, western Nevada, and southeastern California. This report contains only analytical data and sample locations

    Indication-based data on the use of antimicrobials in animals were collected using a prospective cross-sectional survey, similarly as for surveys carried out in human medicine, but adapting the questionnaire to include veterinary-specific issues. The participating veterinarians were randomly selected from a sample population of practising veterinarians. The sampling was stratified to take into account the proportions of different types of veterinary practice in the country. All patients consulting the veterinary practice during a 1-week period were included in the study and veterinarians returned a completed questionnaire for each patient receiving antimicrobial treatment. As cattle received most of the treatments, results from the survey are given using cattle as an example species. The survey was sent to 681 veterinarians, of whom 262 (39%) responded. In total 2850 questionnaires were completed. The largest quantities of antimicrobials, measured in kilograms, were used for cattle, followed by pigs, dogs and horses. The species that were treated most were cattle (n = 1308), dogs (n = 989) and cats (n = 311). For cattle, the most common reason for treatment was acute mastitis (52%), followed by dry-cow therapy (21%), subclinical mastitis (6%) and treatment for acute enteritis (4%). The remaining treatments covered 17% of cattle patients and 15 different indications. For acute mastitis, parenteral or intramammary treatment was used in 36% and 34% of the cases, respectively. The remaining 30% received both treatments simultaneously. Of the parenteral treatments (n = 459), benzyl penicillin was used in 83% of the treated animals (n = 379), while fluoroquinolones were used in 49 cases (11%). Of the 433 cows receiving intramammary treatment, ampicillin combined with cloxacillin was most commonly used (n = 157; 36%), followed by cephalexin+streptomycin (n = 113; 26%). This cross-sectional prospective survey provided a useful method for the collection of information on

    Consumer health information technology can improve patient engagement in their health care and assist in navigating the complexities of health care delivery. However, the consumer health information technology offerings of health systems are often driven by provider rather than patient perspectives and inadequately address patient needs, thus limiting their adoption by patients. Consideration given to patients as stakeholders in the development of such technologies may improve adoption, efficacy, and consumer health information technology resource allocation. The aims of this paper were to measure patient interest in different health system consumer health information technology apps and determine the influence of patient characteristics on consumer health information technology interest. Patients seen at the Cleveland Clinic Neurological Institute were electronically surveyed on their interest in using different consumer health information technology apps. A self-efficacy scale, Patient Health Questionnaire-9 depression screen, and EuroQol 5 dimensions health-related quality of life scale were also completed by patients. Logistic regression was used to determine the influence of patient characteristics on interest in consumer health information technology in the categories of self-management, education, and communication. The majority of 3852 patient respondents had an interest in all technology categories assessed in the survey. The highest interest was in apps that allow patients to ask questions of providers (3476/3852, 90.24%) and to schedule appointments (3211/3839, 83.64%). Patient interest in consumer health information technology was significantly associated with greater depression symptoms, worse quality of life, greater health self-efficacy, and smartphone ownership (Pinformation technology development and their perspectives should consistently guide development efforts. Health systems should consider focusing on consumer health information technologies

    Full Text Available Objectives: The data regarding the health of professional tattooists is inexistent. Tattooists are usually heavily tattooed and exposed daily to body fluids and skin-to-skin contacts with customers, tattoo inks, solvents, allergens, irritants, and work for hours often in inadequate positions using vibrating tattoo machines. We analyzed the health status of active French professional tattooists. Material and Methods: An observational self-reported Internet survey was performed among 448 tattooists who were members of the French Tattoo Union in November 2013. Results: The main physical complaints were musculoskeletal: back pain (65%, finger pain (41.5% and muscular pain (28.8%. Finger pain, back pain, muscular pain and carpal tunnel symptoms/tingling sensations on the fingers occurred among 88%, 61.5%, 68% and 84% of the cases after having started their activity (p < 0.001. Other chronic diseases, autoimmune diseases and cancers remained at a low level here. Conclusions: Professional tattooists have a high prevalence of musculoskeletal complaints about back pain due to repetitive movements, awkward postures and use of a vibrating tattoo machine. Tattooists have a unique environment that imply developing intervention and preventive strategies for them. Int J Occup Med Environ Health 2017;30(1:111–120

    In recent years, the European euthanasia debate has become more intense, and the practice was legalized in the Netherlands, Belgium, and Luxembourg. We aimed to determine the current degree of public acceptance of euthanasia across Europe and investigate what factors explain differences. Data were derived from the 2008 wave of the European Values Survey (EVS), conducted in 47 European countries (N = 67,786, response rate = 69 %). Acceptance of euthanasia was rated on a 1-10 scale. Relatively high acceptance was found in a small cluster of Western European countries, including the three countries that have legalized euthanasia and Denmark, France, Sweden and Spain. In a large part of Europe public acceptance was relatively low to moderate. Comparison with the results of the previous EVS wave (1999) suggests a tendency towards a polarization in Europe, with most of Western Europe becoming more permissive and most of Eastern Europe becoming less permissive. There is roughly a West-East division in euthanasia acceptance among the European public, making a pan-European policy approach to the issue difficult.

    Simulations have shown that bars are subject to a vertical buckling instability that transforms thin bars into boxy or peanut-shaped structures, but the physical conditions necessary for buckling to occur are not fully understood. We use the large sample of local disk galaxies in the Carnegie-Irvine Galaxy Survey to examine the incidence of bars and buckled bars across the Hubble sequence. Depending on the disk inclination angle (I), a buckled bar reveals itself as either a boxy/peanut-shaped bulge (at high I) or as a barlens structure (at low I). We visually identify bars, boxy/peanut-shaped bulges, and barlenses, and examine the dependence of bar and buckled bar fractions on host galaxy properties, including Hubble type, stellar mass, color, and gas mass fraction. We find that the barred and unbarred disks show similar distributions in these physical parameters. The bar fraction is higher (70%-80%) in late-type disks with low stellar mass (M * 1010.5 M ⊙), and decreases with higher gas mass ratio. These results suggest that bars are more difficult to grow in massive disks that are dynamically hotter than low-mass disks. However, once a bar forms, it can easily buckle in the massive disks, where a deeper potential can sustain the vertical resonant orbits. We also find a probable buckling bar candidate (ESO 506-G004) that could provide further clues to understand the timescale of the buckling process.

    We investigate the limitations of statistical absorption measurements with the SDSS optical spectroscopic surveys. We show that changes in the data reduction strategy throughout different data releases have led to a better accuracy at long wavelengths, in particular for sky line subtraction, but a degradation at short wavelengths with the emergence of systematic spectral features with an amplitude of about one percent. We show that these features originate from inaccuracy in the fitting of modeled F-star spectra used for flux calibration. The best-fit models for those stars are found to systematically over-estimate the strength of metal lines and under-estimate that of Lithium. We also identify the existence of artifacts due to masking and interpolation procedures at the wavelengths of the hydrogen Balmer series leading to the existence of artificial Balmer α absorption in all SDSS optical spectra. All these effects occur in the rest-frame of the standard stars and therefore present Galactic longitude variations due to the rotation of the Galaxy. We demonstrate that the detection of certain weak absorption lines reported in the literature are solely due to calibration effects. Finally, we discuss new strategies to mitigate these issues.

    In this work, we apply and expand on a recently introduced outlier detection algorithm that is based on an unsupervised random forest. We use the algorithm to calculate a similarity measure for stellar spectra from the Apache Point Observatory Galactic Evolution Experiment (APOGEE). We show that the similarity measure traces non-trivial physical properties and contains information about complex structures in the data. We use it for visualization and clustering of the data set, and discuss its ability to find groups of highly similar objects, including spectroscopic twins. Using the similarity matrix to search the data set for objects allows us to find objects that are impossible to find using their best-fitting model parameters. This includes extreme objects for which the models fail, and rare objects that are outside the scope of the model. We use the similarity measure to detect outliers in the data set, and find a number of previously unknown Be-type stars, spectroscopic binaries, carbon rich stars, young stars, and a few that we cannot interpret. Our work further demonstrates the potential for scientific discovery when combining machine learning methods with modern survey data.

    The exhibition hall of nuclear power station contributes to understand the visitors about organizations or safety systems through displays and explanations without difficulty. In addition to that, there will be some effect that they give informations to other people after the inspection, so the exhibition hall of nuclear power station plays a vital role of public information considering tens of thousands of yearly visitors. According to that, we made inquiries to the visitors and tried to search what it should be, intending to investigate their actual situation of attitudes or needs, and to accurate effectivities of the present displays in the center of explanations about the organization of nuclear power plant. As a result, the opinion that 'I want to know the organization of nuclear power plant' accounts over 60%, differing from other data of research. And also the opinion after the inspection that 'I am satisfied with acquiring knowledge about the organization' accounts nearly 60%, much higher compared with other choices. In view of these facts, the efficiency of the exhibition hall was certified. The visitor's attitudes of nuclear power is more affirmative than public's one. Even though considering the differences of the survey method, there must be a difference from the first.

    Full Text Available We have developed dual sonar equipment and an improved operating method for improving resolution in order to solve the problems of limitations of the optical equipment and the application method of SSS (side scan sonar in the investigation of damage of underwater structures. We analyzed the influence factors of the resolution of sonar data through the comparison of resolution and data quality in indoor test. Also we confirmed the problems about the overlapping area of the dual sonar. Depth and distance were analyzed as major influencing factors for survey angle. Specimens were scanned while adjusting distance and towfish angle according to depth change in order to verify applicability of the developed dual sonar in the field experiment. Optimal resolution was found to be 3 cm in specimen spacing, and 20 sample data items were extracted. We developed the regression model based on the multiple regression analysis and developed the RealDualSONAR-DAQ tool, the dual sonar optimum operating method program based on proposed correlation equations. We can use the developed tools to get the value of the major influencing factors for dual sonar operation and obtain high quality sonar data to analyze damage of underwater structures.

    Hand hygiene is the single most important measure to prevent transmission of infection, but the compliance rate of healthcare workers is relatively low. This study was conducted to identify the knowledge, beliefs, behavior, and affecting factors about hand hygiene among nursing students. A descriptive survey study. The study was carried out in two South Korean nursing schools. A total 208 nursing students participated in this study. Questionnaires were used to collect data. The percentage of correct answers in the survey section concerning hand hygiene knowledge was 68.1%. No significant difference in the knowledge, behavioral beliefs, normative beliefs, or control beliefs data was found related to general characteristics. Behavioral beliefs correlated with normative beliefs (r=.25, phand hygiene behavior (r=.17, p=.017), and control beliefs correlated with hand hygiene behavior (r=.18, p=.010). The results suggest that knowledge is not enough to change the beliefs related to hand hygiene; positive behavioral beliefs and strong control beliefs are also needed to increase hand hygiene compliance.

    The population of industrialized nations is progressively aging, with Italy having one of the most elderly populations in the world. Natural aging may be associated with physical and cognitive impairments, often straining public resources. The present study aims to investigate the influence of gender on wellness of the nonagenarians. We evaluated quality of life among nonagenarians living in the Mugello area, an Italian location with a large population of individuals > 90 years, using the Health Survey Scoring SF-12. The 15-item Geriatric Depression Scale and Basic and Instrumental Activity of Daily Living scales were also assessed. The Mini-Mental State Examination was used to evaluate the cognitive status. In the current survey, women outnumbered men 2.7:1 confirming their higher longevity. However, on the basis of SF-12 scores, nonagenarian women felt worse than men, both physically (mean: women = 41.8 vs men = 44.4, p = 0.004) and mentally (mean: women = 46.7 vs men =48.5, p = 0.034), and their depression rates were higher: considering a General Depression Scale score ≥ 5 as a possible depression status; 37.5% of men reported depression vs. 48.5% of women (p = 0.021). Significant differences were observed also in daily activities, both basic (median: woman = 3 vs men = 5, p women perform better than men in aging, our study confirms data reported in most national and European surveys: women live longer than men, but with poorer quality of life. The current study confirms the phenomenon known as the "male-female health-survival paradox."

    The electronic chart review habits of intensive care unit (ICU) clinicians admitting new patients are largely unknown but necessary to inform the design of existing and future critical care information systems. We conducted a survey study to assess the electronic chart review practices, information needs, workflow, and data display preferences among medical ICU clinicians admitting new patients. We surveyed rotating residents, critical care fellows, advanced practice providers, and attending physicians at three Mayo Clinic sites (Minnesota, Florida, and Arizona) via email with a single follow-up reminder message. Of 234 clinicians invited, 156 completed the full survey (67% response rate). Ninety-two percent of medical ICU clinicians performed electronic chart review for the majority of new patients. Clinicians estimated spending a median (interquartile range (IQR)) of 15 (10-20) minutes for a typical case, and 25 (15-40) minutes for complex cases, with no difference across training levels. Chart review spans 3 or more years for two-thirds of clinicians, with the most relevant categories being imaging, laboratory studies, diagnostic studies, microbiology reports, and clinical notes, although most time is spent reviewing notes. Most clinicians (77%) worry about overlooking important information due to the volume of data (74%) and inadequate display/organization (63%). Potential solutions are chronologic ordering of disparate data types, color coding, and explicit data filtering techniques. The ability to dynamically customize information display for different users and varying clinical scenarios is paramount. Electronic chart review of historical data is an important, prevalent, and potentially time-consuming activity among medical ICU clinicians who would benefit from improved information display systems.

    Full Text Available Survey and monitoring of soil quality are needed to prevent soil degradation and are important for sustainable farming and food production. Conventional soil survey involves intensive soil sampling and laboratory analysis, which are time consuming and expensive. Visible and near infrared spectroscopy of soil has proved to be accurate, cheap and robust and has huge potential for survey of soil quality. To test its potential, 327 soil samples were taken from long-term paddy rice fields in four provinces in south of China and covered a wide range of soil types and texture. The samples were air-dried, ground and passed through a 2 mm sieve. They were then scanned by an ASD vis–NIR spectrometer with wavelength range from 350 to 2500 nm. Organic matter (OM, pH, total nitrogen (TN and available nitrogen (N_av were also measured on soil samples to build calibration models and also to validate the models’ accuracy. On the basis of the ratio of prediction deviation (RPD, which is standard deviation (SD of prediction divided by the root mean square error of prediction (RMSEP, the accuracy of leave-one-out cross-validation of soil N_av model was classified very good (RPD=1.96 and soil OM and TN was good (RPD=1.78 and RPD=1.81, respectively. However, the model accuracy of pH was poor due to non-direct soil spectral response for soil pH in vis–NIR spectroscopy. The independent validation results showed excellent accuracy for soil N_av (RPD=3.26, good accuracy for OM and TN (RPD=1.76 and RPD=1.78 and relative poor accuracy for soil pH (RPD=1.27. This feasibility study is encouraging for the application of vis–NIR surveys of soil quality accuracy at regional and national scales; it found good to excellent accuracy for some important soil properties in quality survey.

  20. Disease prevalence and the index of detectability: a survey of studies of lung cancer detection by chest radiography

    Kundel, Harold L.

    2000-04-01

    A survey of 12 studies of lung cancer detection with cancer prevalence ranging from 0.9 to 476 cancers per 1000 showed that the unit-slope index of detectability, d', decreased from a high value of 3.9 at low prevalence to 1.4 at high prevalence. A proposed explanation is that the readers are operating on an ROC curve with a slope that is less than unity approximating 0.6. On such a curve, a shift to more stringent criteria that occurs with decreasing prevalence in order to minimize false positives, would result in a increased unity- slope d'.
