    The objective of this study was to develop a methodology for estimating the radiological impact on man of the residues of naturally occurring radioactive materials (NORMs) that potentially can be used for the construction of homes and roads. Residues of this type, which are being produced in great quantities by the Brazilian mining industry, are typically deposited in non-appropriated conditions such that they may have a long-time adverse impact on the environment, and hence on man. A mathematical model was developed to calculate the doses resulting from the use of NORM residues, thus allowing a preliminary analysis of the possibility to recycle the residues. The model was used to evaluate the external dose due gamma radiation, the dose to skin caused by beta radiation, and the internal dose due to inhalation of radon and its decay products. The model was verified by comparisons with results of other studies about doses due to gamma and beta radiation from finite and infinite radioactive sources, with relatively good agreement. In order to validate the proposed methodology, a comparison was made against experimental results for a house constructed in accordance with CNEN regulations using building materials containing NORM residues. Comparisons were made of the dose due to gamma radiation and the radon concentration in the internal environment. Finally, the methodology was used also to estimate the dose caused by gamma radiation from a road constructed in the state of Rondonia, Brazil, which made use of another NORM residue. (author)

    The Dysphagia Outcome and Severity Scale (DOSS) is widely used to measure dysphagia severity based on videofluoroscopy (VFSS). This study investigated inter-rater reliability (IRR) of the DOSS. It also determined the effect of clinical experience, VFSS audio-recording and training on DOSS IRR. A quantitative prospective research design was used. Seventeen speech and language pathologists (SLPs) were recruited from an acute teaching hospital, Dublin (> 3 years' VFSS experience, n = 10) and from a postgraduate dysphagia programme in a university setting (training session on DOSS rating after which DOSS IRR was re-tested. Cohen's kappa co-efficient was used to establish IRR. IRR of the DOSS presented only fair agreement (κ = 0.36, p training (κ = 0.328) was significantly better comparing to post-training (κ = 0.218) (p < 0.05). Findings raise concerns as the DOSS is frequently used in clinical practice to capture dysphagia severity and to monitor changes.

    Uncertainty is a topic that has different meanings to researchers, modelers, managers and policy makers. The perspective of this presentation will be on the modeling view of uncertainty and its quantitative assessment. The goal is to provide some insight into how a statistician visualizes and addresses the issue of uncertainty in ecological risk assessment problems. In ecological risk assessment, uncertainty arises from many sources and is of different type depending on what is studies, where it is studied and how it is studied. Some major sources and their impact are described. A variety of quantitative approaches to modeling uncertainty are characterized and a general taxonomy given. Examples of risk assessments of lake acidification, power plant impact assessment and the setting of standards for chemicals will be used discuss approaches to quantitative assessment of uncertainty and some of the potential difficulties

    Clinical competency and the assessment of core skills is a crucial element of any programme leading to an award with a clinical skills component. This has become a more prominent feature of current reports on quality health care provision. This project aimed to determine ultrasound practitioners' opinions about how best to assess clinical competency. An on-line questionnaire was sent to contacts from the Consortium for the Accreditation of Sonographic Education and details distributed at the British Medical Ultrasound Society conference in 2011. One hundred and sixteen responses were received from a range of clinical staff with an interest in ultrasound assessment. The majority of respondents suggested that competency assessments should take place in the clinical departments with or without an element of assessment at the education centre. Moderation was an important area highlighted by respondents, with 84% of respondents suggesting that two assessors were required and 66% of those stating some element of external moderation should be included. The findings suggest that respondents' preference is for some clinical competency assessments to take place on routine lists within the clinical department, assessed by two people one of which would be an external assessor. In view of recent reports relating to training and assessment of health care professionals, the ultrasound profession needs to begin the debate about how best to assess clinical competence and ensure appropriate first post-competency of anyone undertaking ultrasound examinations.

    Background: Various decisions have been made on technology application at all levels of the health system in different countries around the world. Health technology assessment is considered as one of the best scientific tools at the service of policy- makers. This study attempts to investigate the current challenges of Iran’s health technology assessment and provide appropriate strategies to establish and institutionalize this program. Methods: This study was carried out in two independent phases. In the first, electronic databases such as Medline (via Pub Med) and Scientific Information Database (SID) were searched to provide a list of challenges of Iran’s health technology assessment. The views and opinions of the experts and practitioners on HTA challenges were studied through a questionnaire in the second phase which was then analyzed by SPSS Software version 16. This has been an observational and analytical study with a thematic analysis. Results: In the first phase, seven papers were retrieved; from which, twenty- two HTA challenges in Iran were extracted by the researchers; and they were used as the base for designing a structured questionnaire of the second phase. The views of the experts on the challenges of health technology assessment were categorized as follows: organizational culture, stewardship, stakeholders, health system management, infrastructures and external pressures which were mentioned in more than 60% of the cases and were also common in the views. Conclusion: The identification and prioritization of HTA challenges which were approved by those experts involved in the strategic planning of the Department of Health Technology Assessment will be a step forward in the promotion of an evidence- based policy- making and in the production of comprehensive scientific evidence.

    The workplace assessments, direct observation of procedural skills (DOPS), mini-clinical evaluation exercise (mini-CEX) and multisource feedback (MSF, formerly known as 360 degrees appraisal), are now mandatory during dermatology specialist training in the U.K. The opinions of those undergoing such assessments in any medical specialty have rarely been sought. To collate the experience and views of U.K. dermatology trainees on the three workplace assessments. A questionnaire was circulated in autumn 2006 to all U.K. dermatology specialist registrars (SpRs) registered as members of the British Association of Dermatologists (n = 269). A total of 138 responses were received (51%). Seventeen SpRs had not experienced any of the assessments; 92 had undergone MSF, 95 DOPS and 54 mini-CEX. The total experience of the respondents amounted to a minimum of 251 DOPS, 122 MSF and 142 mini-CEX. Trainees appreciated the formative aspects of the assessments, especially feedback and training opportunities, although not all trainees reported receiving useful feedback. MSF was praised for the insights that it provides. All of the assessments were found to be time-consuming and difficult to organize. DOPS and mini-CEX carried a degree of stress and artificiality. Concerns were raised over the possibility of victimization by MSF raters. Discussion of performance in the assessments was rarely prominent in trainees' annual summative reviews. Trainees appreciate the formative benefits which derive from the assessments, namely feedback, reassurance of satisfactory performance and, in the case of DOPS and mini-CEX, additional one-to-one training from consultants. Some problems came to light. The issues raised will not be unique to dermatology and other specialties should take note.

    We develop a no-reference image quality assessment metric to evaluate the quality of synthesized view rendered from the Multi-view Video plus Depth (MVD) format. Our metric is named Synthesized View Comparison (SVC), which is designed for real-time quality monitoring at the receiver side in a 3D-TV system. The metric utilizes the virtual views in the middle which are warped from left and right views by Depth-image-based rendering algorithm (DIBR), and compares the difference between the virtual views rendered from different cameras by Structural SIMilarity (SSIM), a popular 2D full-reference image quality assessment metric. The experimental results indicate that our no-reference quality assessment metric for the synthesized images has competitive prediction performance compared with some classic full-reference image quality assessment metrics.

    2001-09-01

    The reference sections from all articles in the 1997 volumes of Assessment, Journal of Personality Assessment, and Psychological Assessment were entered into a database and analyzed. An article published in Assessment averaged almost 31 references. An article published in Journal of Personality Assessment contained an average of 33 references. Psychological Assessment averaged 38 references per article. The median age of the references in the three journals was 8 years with an interquartile range of 4 to 14 years. The Journal of Personality Assessment had the largest number of citations in this database of 5,316 references. Each of these received a relatively large number of their citations from articles published in the same journal (self-citations). Randomly selected articles from the 1997 volume of Assessment received fewer citations in the Social Science Citation Index than a similar set of articles from the other two journals. However, the data on Assessment, when compared with data available on other new scientific publications, suggests that Assessment is doing as well as other fledgling journals.

    1989-01-01

    Patients with spondylolytic spondylolisthesis were examined in six different positions to detect segmental instability. The amount of displacement was determined on lateral spot radiographs, taken in recumbent, standing, flexion, extension, axial compression, and traction positions in each patient. An error analysis was also performed. Examination in axial compression - traction was found to be a significantly better method for detection of segmental instability compared with standing - recumbent, or flexion - extension radiographs. In addition, the compression - traction method exhibited a higher sensitivity for identification of instability (73 %) than standing - recumbent (33 %) or flexion - extension (20 %) views. The total error in the determination was small, ± 2.5 % (95 % CL), providing a careful and controlled technique was used. (orig.)

    Full Text Available Objective: This study includes evaluation of views of the nurses working in two different university hospitals on euthanasia. Methods: This research was planned in form of a cross-sectional definitive questionnaire to analyze views of the nurses on euthanasia according to their departments. A face to face interview was performed with the nurses working in Medical Faculties of Dicle and Gaziantep Universities in 2013. One hundred and fifty two volunteers were examined according to the gender, age, marital status, number of children, family type that they live in, the department that they work, their frequency to meet death, professional experience, presence of any relative confined to bed, their ideas on whether the euthanasia law should be enacted, whether they would request euthanasia for themselves and their relatives. Result: Participants included 125 (82.2% women and 27 (17.8% men; average age was 26.68 ± 12.76 (20-56 years and 21 (13.8% cases did not report their ages. Eighty-nine (58.6% participants were married, 50 (32.9% participants were single and 105 (69.1% participants lived in an elementary family environment. Fifty eight (38.2% participants expressed an opinion on requirement of a legal regulation to make euthanasia possible and 40 (26.3% reported that they were uncertain about this subject. No statistically significant difference was detected between willingness and unwillingness of euthanasia according to their departments (p>0.05. Conclusion: As a result of this study, we find that some of the nurses consider application of the passive euthanasia occurs in our country although euthanasia is forbidden.

  2. Physician offices marketing: assessing patients' views of office visits.

    2010-01-01

    Physician offices often lack the sense of incorporating appropriate strategies to make their facilities as marketer of their services. The patient experience at a physician's office not only incorporates the care they receive from the physician but also the other non-healthcare related aspects, such as the behavior of non-health professionals as well as the appearance of the facility itself. This paper is based on a primary research conducted to assess what patients assess from a physician office visit.

    To evaluate the effectiveness of the Robert view in assessing trapeziometacarpal arthrosis and to compare the accuracy of the Robert and lateral views in staging trapeziometacarpal (TM) joint arthrosis. Patient demographics were obtained. Four participating raters reviewed 62 randomly selected thumb x-rays of patients presenting with thumb TM joint pain. Lateral and Robert-hyperpronation views were assessed using an analysis of 13 criteria. X-rays of 62 thumbs for 58 patients were evaluated. The average patients' age was 64 (47-87) and 51 (80%) were females. The majority of X-rays evaluated fell into stage 3. Stage 2 was the second most common level of arthritis encountered and the least was stage 1. More osteophytes were encountered in the trapezium than metacarpal on both the Robert and lateral views. The Robert view was superior in detecting osteophytes on the trapezium than the lateral view. Osteophyte size varied from 1.7 to 2 mm. The lateral view displayed 61 cases with dorsal metacarpal subluxation (98%). The Robert view displayed 48 cases (77%) with radial metacarpal subluxation and 9 cases (15%) with ulnar metacarpal subluxation. Thumb metacarpal adduction deformity was encountered on the lateral view in 20 cases (32%) whereas on the Robert view it was encountered in 14 cases (23%). Subchondral sclerosis was encountered on the Robert view in 56 thumbs (90%) while it was seen on the lateral view in 52 thumbs (84%). Pantrapezial arthritis involving the STT joint was encountered equally in 16 cases (26%) on the Robert view and the lateral views. The study found a moderate level of interrater reliability on both the lateral and Robert views. With the exception of osteophytes encountered on the trapezium versus the metacarpal, there were no other statistically significant findings. This study confirms that each of the Robert and lateral views offer unique information and combining both views enhances the ability to assess radiographic disease severity, and

    2014-09-01

    With the progress of technologies of recent years, methods have become available that use wearable sensors and ambulatory systems to measure aspects of--particular axial--motor function. As Parkinson's disease (PD) can be considered a model disorder for motor impairment, a significant number of studies have already been performed with these patients using such techniques. In general, motion sensors such as accelerometers and gyroscopes are used, in combination with lightweight electronics that do not interfere with normal human motion. A fundamental advantage in comparison with usual clinical assessment is that these sensors allow a more quantitative, objective, and reliable evaluation of symptoms; they have also significant advantages compared to in-lab technologies (e.g., optoelectronic motion capture) as they allow long-term monitoring under real-life conditions. In addition, based on recent findings particularly from studies using functional imaging, we learned that non-motor symptoms, specifically cognitive aspects, may be at least indirectly assessable. It is hypothesized that ambulatory quantitative assessment strategies will allow users, clinicians, and scientists in the future to gain more quantitative, unobtrusive, and everyday relevant data out of their clinical evaluation and can also be designed as pervasive (everywhere) and intensive (anytime) tools for ambulatory assessment and even rehabilitation of motor and (partly) non-motor symptoms in PD. © 2014 John Wiley & Sons A/S.

  5. LEARNING ASSESSMENT VIEWS AND PERCEPTIONS OF FINNISH TEACHERS AND INTERNATIONAL STUDENTS IN POSTGRADUATE PHYSICS STUDIES

    Directory of Open Access Journals (Sweden)

    Roni Tinell

    2017-06-01

    Full Text Available The way teachers view assessment has a considerable impact on their practice of assessment. Student perceptions of assessment, in turn, affect the ways in which they take advantage of its potential to direct their learning processes and to develop metacognitive skills. In this research, physics teachers and international postgraduate students at a Finnish university were surveyed for their views of assessment. The teachers were found to use assessment in a restricted fashion, which indicates that their conceptions of assessment are also limited in scope. The international students appeared to have a loose grasp of the concepts pertaining to assessment. Furthermore, clear differences were found in the purposes ascribed to assessment by the teachers and students. The implications of the findings are discussed and suggestions are made for the development of assessment practices to ensure a better use of its potential as a tool for achieving learning objectives.

    1996-09-01

    When marketing environmentally responsible packaged products, the producer is confronted with consumer beliefs concerning the environmental friendliness of packaging materials. When making environmentally conscious packaging decisions, these consumer beliefs should be taken into account alongside the technical guidelines. Dutch consumer perceptions of the environmental friendliness of packaged products are reported and compared with the results of a life-cycle analysis assessment. It is shown that consumers judge environmental friendliness mainly from material and returnability. Furthermore, the consumer perception of the environmental friendliness of packaging material is based on the postconsumption waste, whereas the environmental effects of production are ignored. From the consumer beliefs concerning environmental friendliness implications are deduced for packaging policy and for environmental policy.KEY WORDS: Consumer behavior; Environment; Food; Packaging; Perception; Waste

    2017-05-01

    Full Text Available This study explored the English/Language Arts teachers’ beliefs and practices in teaching and assessing students’ viewing skills in secondary education in the Philippines. Three secondary teachers in three government-run institutions were surveyed, interviewed and observed regarding their conception of visual literacy. The study revealed that teacher belief is influenced by their early education. In addition, teachers’ ability to teach and assess viewing skills relies not only on teacher training but also on access to technology and availability instrutional materials.  The study suggests a call to strengthen school or government support in order to promote viewing comprehension in basic education to meet the demands of the 21st century.

    The assessment and treatment of childhood medial epicondyle humerus fractures continues to be associated with significant debate. Several studies demonstrate that standard radiographic views are unable to accurately portray the true displacement. Without reliable ways to assess the amount of displacement, how can we debate treatment and outcomes? This study introduces a novel imaging technique for the evaluation of medial epicondyle fractures. An osteotomy of a cadaveric humerus was performed to simulate a medial epicondyle fracture. Plain radiographs were obtained with the fracture fragment displaced anteriorly in 2-mm increments between 0 and 18 mm. Anteroposterior (AP), internal oblique (IR), lateral (LAT), and distal humerus axial (AXIAL) views were performed. Axial images were obtained by positioning the central ray above the shoulder at 15 to 20 degrees from the long axis of the humerus, centered on the distal humerus. Displacement (mm) was measured by 7 orthopaedic surgeons on digital radiographs. At 10 mm displacement, AP views underestimated displacement by 5.5±0.6 mm and IR views underestimated by 3.8±2.1 mm. On LAT views, readers were not able to visualize fragments with displacement. Displacement ≥10 mm from LAT views was overestimated by 1 reader by up to 4.6 mm and underestimated by others by up to 18.0 mm. AXIAL images more closely estimated the true amount of displacement, with a mean 1.5±1.1 mm error in measurement for displacement and a mean 0.8±0.7 mm error for displacements of ≥10 mm. AXIAL measurements correlated strongly with the actual displacement (r=0.998, Pdisplacement of medial epicondyle humerus fractures. The newly described AXIAL projection more accurately and reliably demonstrated the true displacement while reducing the need for advanced imaging such as computed tomography. This simple view can be easily obtained at a clinic visit, enhancing the surgeon's ability to determine the true displacement.

  15. Assessing species habitat using Google Street View: a case study of cliff-nesting vultures.

    Full Text Available The assessment of a species' habitat is a crucial issue in ecology and conservation. While the collection of habitat data has been boosted by the availability of remote sensing technologies, certain habitat types have yet to be collected through costly, on-ground surveys, limiting study over large areas. Cliffs are ecosystems that provide habitat for a rich biodiversity, especially raptors. Because of their principally vertical structure, however, cliffs are not easy to study by remote sensing technologies, posing a challenge for many researches and managers working with cliff-related biodiversity.

    This study aimed to evaluate agreement among three methods for cervical vertebral maturation (CVM) assessment, comprising direct viewing, tracing only, and tracing with digitized points. Two examiners received training and tests of reliability with each CVM method before evaluation of agreement among methods. The subjects were 96 female-cleft lateral cephalometric radiographs (films of eight subjects for each age ranged from seven to 18 years). The examiners interpreted CVM stages of the subjects with four-week interval between uses of each method. The range of weighted kappa values for paired comparisons among the three methods were: 0.96-0.98 for direct viewing and tracing only comparison; 0.93-0.94 for direct viewing and tracing with digitized points comparison; and 0.96-0.97 for tracing only and tracing with digitized points comparison. The intraclass correlation coefficient (ICC) value among the three methods was 0.95. These results indicated very good agreement among methods. Use of direct viewing is suitable for CVM assessment without spending more time for tracing. However, the three methods might be used interchangeably.

    Objective assessment of surgical and technical skills (OSATS) workplace-based assessment tool is now mandatory during ophthalmology speciality training in the United Kingdom. The opinions of those undergoing this assessment have not been formally sought. This study evaluated the views of ophthalmology trainees on OSATS assessment as applied to cataract surgery. A questionnaire was circulated to 34 ophthalmology speciality trainees of the Mersey deanery. A total of 28 responses were received. The most positive aspects of the process identified were feedback, learning and opportunity for reflective practice. The most negative aspects were time constraints, assessor's availability and case selection. Of the trainees, 93 % mentioned that no previous agreed action was taken into consideration when filling in subsequent forms and their performance was not discussed in their annual summative assessment. This study highlights important aspects of trainees' perceptions of OSATS. Trainees appreciate the formative aspects of OSATS assessment. Some problems came to light, which can be resolved by specification of standards, training of assessors, and commitment from both trainers and trainees. Changes are needed to allow demonstration of surgical progression with time. The issues identified here will be relevant to other specialities as well. A larger survey would be beneficial.

    This study aims to explore the views of members of theater teams regarding the proposed introduction of a workplace-based assessment of nontechnical skills of surgeons (NOTSS) into the Intercollegiate Surgical Curriculum Programme in the United Kingdom. In addition, the previous training and familiarity of the members of the surgical theater team with the concept and assessment of NOTSS would be evaluated. A regional survey of members of theater teams (consultant surgeons, anesthetists, scrub nurses, and trainees) was performed at 1 teaching and 2 district general hospitals in South Yorkshire. There were 160 respondents corresponding to a response rate of 81%. The majority (77%) were not aware of the NOTSS assessment tool with only 9% of respondents reporting to have previously used the NOTSS tool and just 3% having received training in NOTSS assessment. Overall, 81% stated that assessing NOTSS was as important as assessing technical skills. Trainees attributed less importance to nontechnical skills than the other groups (p ≤ 0.016). Although opinion appears divided as to whether the presence of a consultant surgeon in theater could potentially make it difficult to assess a trainee's leadership skills and decision-making capabilities, overall 60% agree that the routine use of NOTSS assessment would enhance safety in the operating theater and 80% agree that the NOTSS tool should be introduced to assess the nontechnical skills of trainees in theater. However, a significantly lower proportion of trainees (45%) agreed on the latter compared with the other groups (p = 0.001). Our survey demonstrates acceptability among the theater team for the introduction of the NOTSS tool into the surgical curriculum. However, lack of familiarity highlights the importance of faculty training for assessors before such an introduction. Copyright © 2015 Association of Program Directors in Surgery.

    Full Text Available NOS form B is an instrument that has been developed and revised to assess the view of nature of science of preservice science teachers through nature of science aspects.Indeed, students and teachers have to have the view of nature of science to avoid misconceptions of science concepts. Unfortunately, research on the view of Nature of Science is less conducted in Indonesia. This is a qualitative research that was conducted in Borneo University Tarakan. Respondents are preservice biology teachers in the sixth semester. The first step of this research is translating and adapting the VNOS form B into Bahasa Indonesia to make sure that the instrument is culturally fit to Indonesian and the transadapted instrument then given to the respondents. The result shows that the VNOS form B can be applied to assess the view of nature of science of preservice biology teachers. However, the result also shows that most of preservice biology teachers have few understanding on aspects of nature of scince.

    The paper describes the background to the seismic assessment of existing nuclear structures in the United Kingdom. Nuclear installations in this country were not designed specifically to resist earthquakes until the nineteen-seventies, although older plants were robustly constructed. The seismic capability of these older installations is now being evaluated as part of the periodic safety reviews which nuclear licensees are required to carry out. The regulatory requirements which set the framework for these studies are explained. The licensees' processes of hazard appraisal and examination of the response of the structure are briefly summarized. Regulatory views on some of the criteria used to judge the adequacy of safety are discussed. Finally the paper provides some comments on future initiatives and possible areas of development.

    This book disentangles the issues in connection with the advancement of Health Technology Assessment (HTA) and its interface with health policy. It highlights the factors that should shape its progress in the near future. Interdisciplinary and critical views from a number of professionals are put together in a prescient order to cast some light and make recommendations as to the next steps HTA should take to be fit for purpose. A wealth of documents dealing with HTA have been published over the last three decades. HTA allegedly is one of the bedrocks of regulation and medical decision making. However, counter vailing visions contend that geographical variations in the role that HTA is actually playing within countries pinpoints specific room for improvement. Given our social preferences, cherry-picking HTA's features and successes over the last decades moves it away from its possibility frontier. Some of the most noteworthy hindrances that HTA faces, in several countries, to making headway towards its consoli...

  4. Paediatricians' views on their role in the assessment and management of ADHD and autism.

    ADHD and Autistic Spectrum Disorders (ASD) are a core component of paediatricians case work in the U.K. and U.S., but the situation in Ireland is less clear. Due to significant underdevelopment of Child and Adolescent Mental Health Services in Ireland, long waiting lists may delay identification and treatment. The aim of our study was to explore the views of a group of paediatricians in relation to their current and future practice of assessing and managing ADHD and ASD. The outcome of our study indicated that more than half of the paediatricians surveyed are directly involved in the assessment or treatment of ADHD and ASD. Eighty five per cent (85%) of paediatricians believed that they should have a role in the assessment of ADHD and ASD and over half had thought that they should be involved in managing ADHD and ASD. These results suggest that there is potential to develop alternative specialist services in Ireland for the identification and treatment of children with ADHD and ASD. The development of a well coordinated integrated care pathway may reduce waiting times for families and lead to easier access to services.

    To compare the hindfoot alignment measured on standing HAV radiographs (Saltzman view) and on non-weight-bearing coronal MR images. The apparent moment arm was measured on weight-bearing conventional radiographs (Saltzman views) and on MRIs of the ankle in 50 consecutive patients (mean age, 54 years; age range, 18-77 years). The evaluation was performed independently by three readers using analogous reference points for both methods. Positive values were assigned when the deepest point of the calcaneus was lateral to the tibial axis as valgus, negative values as varus. The intertechnique agreement and correlation for the measurements performed with HAV radiographs and MRI were assessed for each reader using the Bland-Altman method and the Pearson correlation coefficient, respectively. The interobserver agreement was assessed using the intraclass correlation coefficient. The means of apparent moment arms, with the standard deviation (SD) in parentheses, of three readers were +2.0 (±8.4) mm, +1.5 (±6.6) mm and -1.4 (±8.2) mm on HAV radiographs and +4.6 (±7.4) mm, +6.3 (±5.3) mm and +5.4 (±6.4) mm on MRI. The Bland-Altman analysis found a systematic bias for all three readers, corresponding to an overestimation of measurements with MRI (systematic bias ranging from 2.6 to 4.8 mm). The intertechnique correlation was found moderate to high. The Pearson coefficients for the three readers were 0.75, 0.64 and 0.65. The interobserver agreement among the three readers was 0.72, 0.77 and 0.68 for HAV, MRI and both modalities together, respectively. Hindfoot alignment can be estimated on MRI but the correlation between the values on HAV radiographs and MR images is only moderate with a tendency to increased positive values (valgization) on MR images.

    The intrinsic characteristics of iodine make it a relevant concern as to its potential radiobiological impact in case of a hypothetical severe accident in nuclear power plants. This paper summarizes the major results drawn from a very simple but illustrative calculation exercise aimed at weighing how significant could be taking iodine chemistry in containment into account for source term assessments in case of a postulated severe reactor accident. The scenario chosen as representative of expected conditions in containment was LA-4 test of LACE programme. Several approximations and hypothesis concerning the scenario were necessary. Iodine chemistry analyses were performed with IODE code, as long as thermalhydraulic and aerosol behaviour analyses, providing initial and boundary conditions for iodine calculations, were carried out with CONTEMPT4/MOD5 and NAUA/MOD5 codes, respectively. In general, the results obtained agreed qualitatively with the current knowledge on the area; from a quantitative point of view, one of the major results was that iodine chemistry on acidic conditions could provide a substantial increase in the leaked mass from containment under the postulated circumstances. Hence, this study underlines the need of including iodine chemistry in source tenn assessments. (author)

    Basic communication research has identified a major social problem: communicating about cancer from diagnosis through death of a loved one. Over the past decade, an award-winning investigation into how family members talk through cancer on the telephone, based on a corpus of 61 phone calls over a period of 13 months, has been transformed into a theatrical production entitled The Cancer Play. All dialogue in the play is drawn from naturally occurring (transcribed) interactions between family members as they navigate their way through the trials, tribulations, hopes, and triumphs of a cancer journey. This dramatic performance explicitly acknowledges the power of the arts as an exceptional learning tool for extending empirical research, exploring ordinary family life, and exposing the often taken-for-granted conceptions of health and illness. In this study, a Phase I STTR project funded by the National Cancer Institute (NCI), we assess the feasibility of educating and impacting cancer patients, family members, and medical professionals who viewed the play as a live performance and through DVD screenings. Pre- and postperformance questionnaires were administered to solicit audience feedback. Pre-post change scores demonstrate overwhelming and positive impacts for changing opinions about the perceived importance, and attributed significance, of family communication in the midst of cancer. Paired-sample t-tests were conducted on five factor-analyzed indices/indicators-two indices of opinions about cancer and family communication, two indices measuring the importance of key communication activities, and the self-efficacy indicator-and all factors improved significantly (<.001). Informal talkback sessions were also held following the viewings, and selected audience members participated in focus groups. Talkback and focus-group sessions generated equally strong, support responses. Implications of the Phase I study are being applied in Phase II, a currently funded effort to

    Small islands have the attention of the international community because they are territories with unique features, and a pressing need for the enhancement of sustainability. Strategic Environmental Assessment (SEA) has characteristics that may promote the development and improvement of sustainability in these territories: (i) changing the mind-set, and the decision-making and institutional paradigm, (ii) facilitating cooperation and coordination between different stakeholders, and (iii) providing a framework for good governance and community empowerment. The scientific literature suggests that there may be a need for context-specific SEA in these territories. However, SEA studies often do not incorporate local contextual information, including intuitive knowledge and sense of place. Therefore, there is a possible gap between what is found in the literature and what local communities think, including different stakeholders and experts. Hence, the main goal of this research was to gain an insight into the views and perspectives of small islands SEA experts about issues related to SEA in European small islands, including context-specific approaches, as well as the contribution of SEA for sustainability in these territories. To achieve the research aim, exploratory research using a questionnaire-based survey was designed, aimed at experts on SEA in European small islands. Findings showed regional cooperation networks may have a fundamental role when developing SEA-specific approaches in these territories. This is because SEA-specific approaches encourage a joint effort among islands within one region to improve SEA capacity-building, develop and share a baseline information system, and to share and exchange resources, overall. Also, guidelines are preferred among experts over more legal frameworks and regulations. Finally, the research showed that experts view SEA as a way to enhance sustainability in small islands. This study highlights the importance of integrating

    The Useful Field of View (UFOV) assessment, a measure of visual speed of processing, has been shown to be a predictive measure of motor vehicle collision (MVC) involvement in an older adult population, but it remains unknown whether UFOV predicts commercial motor vehicle (CMV) driving safety during secondary task engagement. The purpose of this study is to determine whether the UFOV assessment predicts simulated MVCs in long-haul CMV drivers. Fifty licensed CMV drivers (Mage = 39.80, SD = 8.38, 98% male, 56% Caucasian) were administered the 3-subtest version of the UFOV assessment, where lower scores measured in milliseconds indicated better performance. CMV drivers completed 4 simulated drives, each spanning approximately a 22.50-mile distance. Four secondary tasks were presented to participants in a counterbalanced order during the drives: (a) no secondary task, (b) cell phone conversation, (c) text messaging interaction, and (d) e-mailing interaction with an on-board dispatch device. The selective attention subtest significantly predicted simulated MVCs regardless of secondary task. Each 20 ms slower on subtest 3 was associated with a 25% increase in the risk of an MVC in the simulated drive. The e-mail interaction secondary task significantly predicted simulated MVCs with a 4.14 times greater risk of an MVC compared to the no secondary task condition. Subtest 3, a measure of visual speed of processing, significantly predicted MVCs in the email interaction task. Each 20 ms slower on subtest 3 was associated with a 25% increase in the risk of an MVC during the email interaction task. The UFOV subtest 3 may be a promising measure to identify CMV drivers who may be at risk for MVCs or in need of cognitive training aimed at improving speed of processing. Subtest 3 may also identify CMV drivers who are particularly at risk when engaged in secondary tasks while driving.

  11. Danube quality water assessment from the microbiological point of view in Cernavoda nuclear plant area

    2003-01-01

    Herein are analysed the following microbiological parameters: total viable count, total coliforms and faecal coliforms, which represent a standard indicator for water quality. The study has been done during 1998-2002 upon the water in the Danube River and in the channels for cooling water used by Cernavoda Nuclear Power Plant condensers. In this area, based on these values of evaluated parameters, the water feature is placed in the quality classes II and III (moderate and critical pollution), in conformity with European Community Directives. Bacterial communities, component part of aquatic biocenoses, are very important for matter and energy flux. Their contribution to self-purification processes of rivers is of great interest related to the water quality assessment. Microorganisms are ideal sensors, because they respond fast to the fluctuation of environmental conditions by specific changes, detectable physiologically and metabolically. The temperature is a major factor, which directly affects the intensity of all microbial processes. Because the microorganisms are interconnected with the other living organisms, the qualitative or quantitative changes of their activity will affect the functions of the whole ecosystem. Bacterial indicators such as total viable count (colony count), total coliforms or faecal coliforms (thermo-tolerant coliforms) are widely applied to the assessment of water quality. Because of their mostly allochthonus origin, these are used as indicators of changes in the natural water conditions; they point out an organic matter or faecal water pollution. Although the water quality can be considered acceptable from the chemical or biological point of view, the bacteriological parameters might be detected in critical concentration. The objectives of this microbiological assessment are analysis of the variation of bacteriological indicators in some sampling points of Cernavoda aquatic ecosystems area, and monitoring the manner of using the water by

    Car surveys (CS) are a common method for assessing the distribution of alien invasive plants. Google Street View (GSV), a free-access web technology where users may experience a virtual travel along roads, has been suggested as a cost-effective alternative to car surveys. We tested if we could replicate the results from a countrywide survey conducted by car in Portugal using GSV as a remote sensing tool, aiming at assessing the distribution of Eucalyptus globulus Labill. wildlings on roadsides adjacent to eucalypt stands. Georeferenced points gathered along CS were used to create road transects visible as lines overlapping the road in GSV environment, allowing surveying the same sampling areas using both methods. This paper presents the results of the comparison between the two methods. Both methods produced similar models of plant abundance, selecting the same explanatory variables, in the same hierarchical order of importance and depicting a similar influence on plant abundance. Even though the GSV model had a lower performance and the GSV survey detected fewer plants, additional variables collected exclusively with GSV improved model performance and provided a new insight into additional factors influencing plant abundance. The survey using GSV required ca. 9 % of the funds and 62 % of the time needed to accomplish the CS. We conclude that GSV may be a cost-effective alternative to CS. We discuss some advantages and limitations of GSV as a survey method. We forecast that GSV may become a widespread tool in road ecology, particularly in large-scale vegetation assessments.

Subsequently, the ‘Global Network for Disaster Reduction’ (GNDR was formed to support the implementation of the HFA. The GNDR initiated a country-based, international research project called ‘Views from the Frontline’ (VFL in order to measure progress at local level in terms of compliance with the HFA. The VFL 2011 project focused on local risk governance, which is critical for effective implementation of policy and provision of resources at grassroots level. This article provides insight into the findings for South Africa. The project made use of quantitative and qualitative data. Quantitative data was gathered by means of a survey and/or questionnaire consisting of 20 questions on ‘indicators’ which assessed progress toward the goals of the HFA. The surveys also provided for qualitative commentary. The target population for this research consisted of local government officials and community representatives. Based on the quantitative scores for all the different indicators, the research showed that South Africa could still improve significantly in terms of compliance with the HFA. More attention must be given to operationalise the HFA at local level, a culture of safety must be fostered, local actors and communities must be involved directly and consulted, indigenous knowledge must be recognised, and significant capacity development for disaster risk reduction is necessary.

    Full Text Available Since WorldView-2 (WV-2 images are widely used in various fields, there is a high demand for the use of high-quality pansharpened WV-2 images for different application purposes. With respect to the novelty of the WV-2 multispectral (MS and panchromatic (PAN bands, the performances of eight state-of-art pan-sharpening methods for WV-2 imagery including six datasets from three WV-2 scenes were assessed in this study using both quality indices and information indices, along with visual inspection. The normalized difference vegetation index, normalized difference water index, and morphological building index, which are widely used in applications related to land cover classification, the extraction of vegetation areas, buildings, and water bodies, were employed in this work to evaluate the performance of different pansharpening methods in terms of information presentation ability. The experimental results show that the Haze- and Ratio-based, adaptive Gram-Schmidt, Generalized Laplacian pyramids (GLP methods using enhanced spectral distortion minimal model and enhanced context-based decision model methods are good choices for producing fused WV-2 images used for image interpretation and the extraction of urban buildings. The two GLP-based methods are better choices than the other methods, if the fused images will be used for applications related to vegetation and water-bodies.

    The aim of this study was to investigate originator pharmaceutical companies' practices in relation to health technology assessment (HTA) and the views and perceptions of their executives on the importance of HTA in pricing and reimbursement of medicines in Greece. A qualitative study was performed, using individual semi-structured interviews based on an interview schedule with open-ended questions. The target population was market access departments' executives of originator pharmaceutical companies. Our target sample consisted of sixteen executives, of whom ten agreed to participate. Saturation point was reached after eight interviews. Data were audio recorded, transcribed verbatim, and analyzed using content analysis. Participants considered HTA as a very important complementary tool for decision making in health policy, particularly in the field of pharmaceuticals and medical devices. They believed that, in Greece, HTA could be institutionalized for the reimbursement mechanism of medicines under certain conditions relating to current health policy-making attitudes and conditions pertaining in the country. They considered that there are many constraints which must be overcome as well as opportunities to be exploited. Decisions in pharmaceutical policy should be scientifically substantiated and HTA should be institutionalized primarily for reimbursement decisions. Development of guidelines for conducting pharmaco-economic evaluation, change in health policy goals, recording of cost and epidemiological data, and broader participation of all stakeholders in HTA decision-making processes are suggested as prerequisites for a successful implementation of HTA in Greece.

  16. Assessing views about gun violence reduction policy: a look at type of violence and expected effectiveness.

    Public opinion polling about gun policy is routinely conducted and often disregarded. The purpose of this research is to explore ways in which surveys can be made more useful to policy makers, researchers, and the general public. A stratified random sample of 1000 undergraduates at a private, urban university was recruited for an online survey about proposed gun policies. A total of 51.7% answered the questions analyzed herein. Including but going beyond typical assessments of agreement, the survey elicited respondent evaluations of the effectiveness of seven gun policies under two randomly assigned conditions: the type of gun violence (e.g., homicide, suicide, violent crime) and its magnitude. Participants were asked to estimate the effectiveness of each policy, including the possibility of making things worse. Participants indicated strong support for all policies and expected each to be effective with one exception - a policy designed to increase the number of guns on the scene, that is, putting armed police in schools. Persons who did not support other policies, on average, did not expect them to make things worse. Telling participants about the scope of the violence did not but the type of gun violence did affect effectiveness ratings. Asking about expected effectiveness of (vs. general support for) a policy might identify some optimism: Even people who don't support a policy sometimes think it will be effective. Findings suggest that surveys about the effectiveness of gun violence policies likely assess views that exclude suicide, the most common form of gun-related mortality. Copyright © 2015 Elsevier Inc.

  17. Views of nature of science questionnaire: Toward valid and meaningful assessment of learners' conceptions of nature of science

    Lederman, Norm G.; Abd-El-Khalick, Fouad; Bell, Randy L.; Schwartz, Renée S.

    2002-08-01

    Helping students develop informed views of nature of science (NOS) has been and continues to be a central goal for kindergarten through Grade 12 (K-12) science education. Since the early 1960s, major efforts have been undertaken to enhance K-12 students and science teachers' NOS views. However, the crucial component of assessing learners' NOS views remains an issue in research on NOS. This article aims to (a) trace the development of a new open-ended instrument, the Views of Nature of Science Questionnaire (VNOS), which in conjunction with individual interviews aims to provide meaningful assessments of learners' NOS views; (b) outline the NOS framework that underlies the development of the VNOS; (c) present evidence regarding the validity of the VNOS; (d) elucidate the use of the VNOS and associated interviews, and the range of NOS aspects that it aims to assess; and (e) discuss the usefulness of rich descriptive NOS profiles that the VNOS provides in research related to teaching and learning about NOS. The VNOS comes in response to some calls within the science education community to go back to developing standardized forced-choice paper and pencil NOS assessment instruments designed for mass administrations to large samples. We believe that these calls ignore much of what was learned from research on teaching and learning about NOS over the past 30 years. The present state of this line of research necessitates a focus on individual classroom interventions aimed at enhancing learners' NOS views, rather than on mass assessments aimed at describing or evaluating students' beliefs.

    2013-09-01

    Traditionally, written examination and clinical practice assessments are the main ways of deeming midwifery students fit and competent for practice. Contemporary academics in an effort to engage the students in the learning process have employed alternative teaching and assessment strategies. Among the alternative strategies are group projects after which members of the group are awarded the same grade, and peer assessment. With the purpose of informing the midwifery curricular, we utilised a qualitative descriptive approach to explore midwifery students' experiences and views on the use of group poster presentation for learning and assessment. The participants consisted of a purposive sample of 14 higher diploma midwifery students who were registered in a third level institution in Ireland. Semi-structured individual interviews were conducted following the completion of the poster presentation assessment. Permission to undertake the study was obtained from the college ethics committee. In this paper, we focus on the participants' views of group marking and peer assessment which are among the key elements that emerged in this study. While awarding a group mark was overall accepted, peer assessment proved a more contentious issue. Most of the participants found it challenging marking their friends. Reactions to group marks were very much influenced by the group dynamics. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Driving is important for older people to maintain agency, independence and social connectedness. Little research has been conducted into the views of older people with mild cognitive impairment about who decides if they are safe to drive. This qualitative study investigates the views of older people with mild cognitive impairment about decision making on driving cessation. Participants value their agency; they wanted to decide when they should stop driving themselves. However, they were also prepared to accept their general practitioner's advice when they became unfit to drive. In the interim, they self regulated the timing and distance of their driving to reduce accident risk.

  6. Accuracy Assessment of Digital Surface Models Based on WorldView-2 and ADS80 Stereo Remote Sensing Data

    Directory of Open Access Journals (Sweden)

    2012-05-01

    Full Text Available Digital surface models (DSMs are widely used in forest science to model the forest canopy. Stereo pairs of very high resolution satellite and digital aerial images are relatively new and their absolute accuracy for DSM generation is largely unknown. For an assessment of these input data two DSMs based on a WorldView-2 stereo pair and a ADS80 DSM were generated with photogrammetric instruments. Rational polynomial coefficients (RPCs are defining the orientation of the WorldView-2 satellite images, which can be enhanced with ground control points (GCPs. Thus two WorldView-2 DSMs were distinguished: a WorldView-2 RPCs-only DSM and a WorldView-2 GCP-enhanced RPCs DSM. The accuracy of the three DSMs was estimated with GPS measurements, manual stereo-measurements, and airborne laser scanning data (ALS. With GCP-enhanced RPCs the WorldView-2 image orientation could be optimised to a root mean square error (RMSE of 0.56 m in planimetry and 0.32 m in height. This improvement in orientation allowed for a vertical median error of −0.24 m for the WorldView-2 GCP-enhanced RPCs DSM in flat terrain. Overall, the DSM based on ADS80 images showed the highest accuracy of the three models with a median error of 0.08 m over bare ground. As the accuracy of a DSM varies with land cover three classes were distinguished: herb and grass, forests, and artificial areas. The study suggested the ADS80 DSM to best model actual surface height in all three land cover classes, with median errors < 1.1 m. The WorldView-2 GCP-enhanced RPCs model achieved good accuracy, too, with median errors of −0.43 m for the herb and grass vegetation and −0.26 m for artificial areas. Forested areas emerged as the most difficult land cover type for height modelling; still, with median errors of −1.85 m for the WorldView-2 GCP-enhanced RPCs model and −1.12 m for the ADS80 model, the input data sets evaluated here are quite promising for forest canopy modelling.

    Mapping species spatial distribution using spatial inference and prediction requires a lot of data. Occurrence data are generally not easily available from the literature and are very time-consuming to collect in the field. For that reason, we designed a survey to explore to which extent large-scale databases such as Google maps and Google street view could be used to derive valid occurrence data. We worked with the Pine Processionary Moth (PPM) Thaumetopoea pityocampa because the larvae of that moth build silk nests that are easily visible. The presence of the species at one location can therefore be inferred from visual records derived from the panoramic views available from Google street view. We designed a standardized procedure allowing evaluating the presence of the PPM on a sampling grid covering the landscape under study. The outputs were compared to field data. We investigated two landscapes using grids of different extent and mesh size. Data derived from Google street view were highly similar to field data in the large-scale analysis based on a square grid with a mesh of 16 km (96% of matching records). Using a 2 km mesh size led to a strong divergence between field and Google-derived data (46% of matching records). We conclude that Google database might provide useful occurrence data for mapping the distribution of species which presence can be visually evaluated such as the PPM. However, the accuracy of the output strongly depends on the spatial scales considered and on the sampling grid used. Other factors such as the coverage of Google street view network with regards to sampling grid size and the spatial distribution of host trees with regards to road network may also be determinant.

    To meet the UN millennium development goal of reducing the number of hungry people to half by 2015, there is utmost need to breed potentially high yielding varieties to match up the requirement along with corrective measures to bridge the gap between the potential yield and yield harvested by farmers. The scenario has changed from free access to limited access of plant genetic resources (PGR) and therefore, it is important to understand the issues in view of national and international agreements, intellectual property rights (IPR'S), climate change conditions and expanded scope of breeders and farmers rights for developed genotypes. For efficient management of PGR, developing countries need to understand the implications of PGR related IPR'S as stronger IPR'S in developed countries could have harmful effects by reduced exchange of genetic resources from developed countries. Keeping in view the existing realities every possible effort should be taken for enrichment of crop gene pool by introducing them from each and every corner of the globe. Keeping these facts in view this paper describes the priorities for introduction and exchange of important crop groups/crops along with some of their potential wild and weedy relatives and thrust has been given to generate awareness among the workers engaged in the breeders/crop improvement works. Information provided in this presentation can be utilized by prospective crop improvement works to plan to meet out the nationalfood security.

    Research on students' views on nature of science (VNOS) in Asian countries such as China is notably lacking. This study aimed to develop and validate an instrument to measure South China high school students' VNOS. Based on the previously acquired qualitative data, the instrument included seven VNOS dimensions which reflect the crucial aspects of NOS indicated by the literature and/or the dominating ideology in China (i.e., Marxism). A sample (N = 604) was randomly divided into two groups used for exploratory analyses and confirmatory analyses. The results indicated that the instrument expressed satisfactory reliability and validity and the seven NOS dimensions could be explained by a higher-order dimension. That is, the data of this study supported the multi-dimensional framework that treats VNOS as comprising several more-or-less correlated dimensions. Two distinct dimensions, namely "Accumulative-Empirical Source" and "Pragmatic Justification" which have not been explicitly specified in the past literature, were found. In addition, the Chinese high school students generally held a constructivist/relativist-oriented view of all seven dimensions. Differences in gender and grade level were hardly observed in any dimension of the instrument. The findings are further discussed through a socio-cultural lens to enrich the current understanding of VNOS.

    Full Text Available The purpose of this study was to analyze peer mediation process that was applied in a high school on conflicting students’ point of views. This research was carried out in a high school in Denizli. After ten sessions of training in peer mediation, peer mediators mediated peers’ real conflicts. In the research, 41 students (28 girls, 13 boys who got help at least once were interviewed as a party to the conflict. Through semistructured interviews with conflicting students, the mediation process has been evaluated through the point of views of students. Eight questions were asked about the conflicting parties. Verbal data obtained from interviews were analyzed using the content analysis. When conflicting students’ opinions and experiences about peer mediation were analyzed, it is seen that they were satisfied regarding the process, they have resolved their conflicts in a constructive and peaceful way, their friendship has been continuing as before. All of these results also indicate that peer mediation is an effective method of resolving student conflicts constructively

    Patients are increasingly turning to the internet to seek reliable sources of health information and desire guidance in assessing the quality of information as healthcare becomes progressively more complex. Pituitary adenomas are a rare, diverse group of tumors associated with increased mortality and morbidity whose management requires a multidisciplinary approach. As such, patients with this disorder are often searching for additional sources of healthcare information. We undertook a study to assess the quality of information available on the internet for patients with pituitary adenoma. After exclusion, 42 websites were identified based on a search engine query with various search terms. Each website was assessed in triplicate: once by a health professional, once by a simulated patient, and once by a patient who had a pituitary adenoma and underwent medical and surgical treatment. The assessment tools included a content-specific questionnaire, the DISCERN tool, and the Ensuring Quality Information for Patients tool. The readability of the information was assessed with the Flesch-Kincaid grade level. We found that the overall quality of information on pituitary adenoma on the internet was variable and written at a high grade level. Correlation between the different assessors was poor, indicating that there may be differences in how healthcare professionals and patients view healthcare information. Our findings highlight the importance of assessment of the health information by groups of the intended user to ensure the needs of that population are met. Abbreviation: EQIP = Ensuring Quality Information for Patients.

  16. Role and meaning of safety assessment from the point of view of IAEA

    International Nuclear Information System (INIS)

    Lyubarskiy, A.

    2012-01-01

    In 2006, the IAEA published its revised Safety Fundamentals. This states that the ''fundamental safety objective is to protect people and the environment from harmful effects of ionizing radiation''. This objective has to be achieved for all facilities and activities and for all stages over the lifetime of a facility by adherence to ten fundamental principles. This leads, inter alia, to the requirement for a safety assessment to be carried out. In particular, the text accompanying Principle 3 on leadership and management for safety states that: ''3.15. Safety has to be assessed for all facilities and activities, consistent with a graded approach. Safety assessment involves the systematic analysis of normal operation and its effects, of the ways in which failures might occur and of the consequences of such failures. Safety assessments cover the safety measures necessary to control the hazard, and the design and engineered safety features are assessed to demonstrate that they fulfill the safety functions required of them. Where control measures or operator actions are called on to maintain safety, an initial safety assessment has to be carried out to demonstrate that the arrangements made are robust and that they can be relied on. A facility may only be constructed and commissioned or an activity may only be commenced once it has been demonstrated to the satisfaction of the regulatory body that the proposed safety measures are adequate.'' Principle 3 further states that the process of safety assessment for facilities and activities is repeated in the conduct of operations in order to take into account changed circumstances (such as the application of new standards or scientific and technological developments), the feedback of operating experience, modifications and the effects of ageing. Continuation of operations over long periods of time requires reassessments demonstrating that the safety measures remain adequate. (orig.)

  17. Nuclear utility self-assessment as viewed by the corporate nuclear safety committee

    International Nuclear Information System (INIS)

    Corcoran, W.R.

    1992-01-01

    This paper discusses how corporate nuclear safety committees use the principles of self-assessment to enhance nuclear power plant safety performance. Corporate nuclear safety committees function to advise the senior nuclear power executive on matters affecting nuclear safety. These committees are required by the administrative controls section of the plant technical specifications which are part of the final safety analysis report and the operating license. Committee membership includes senior utility executives, executives from sister utilities, utility senior technical experts, and outside consultants. Current corporate nuclear safety committees often have a finely tuned intuitive feel for self-assessment that they use to probe the underlying opportunities for quality and safety enhancements. The questions prompted by the self-assessment orientation enable the utility line organization members to gain better perspectives on the characteristics of the organizational systems that they manage and work in

    Purpose: ViewRay is a novel image-guided radiotherapy approach with an integrated 0.35 T MR unit and three Cobalt-60 heads. In order to continuously ensure the high resolution and high soft tissue contrast available in MR images, we quantified a multitude of relevant imaging parameters over a period of six months to establish its stability and imaging quality. In the assessment process, consideration is also given to the need to establish the number of tests required to have confidence in the performance of the system for radiation therapy planning applications. Methods: Daily, weekly, monthly and annual imaging tests were performed over a period of six months using standardized phantoms (a 24 cm diameter sphere and the ACR phantom) to quantify the performance of the system. In addition to the ACR and NEMA recommended tests, we also included element testing, spatial integrity, Eddy current and magnetic field inhomogeneity measurements. The ACR test is used for assessing the following parameters for T1 and T2: geometric accuracy, high contrast spatial resolution, slice thickness accuracy, slice position accuracy, percent signal ghosting, low contrast object detectability. It also includes percent image uniformity (PIU) for T1. The NEMA test is primarily designed to check SNR and PIU. Results: Over the period of six months, all the parameters were maintained within the recommendations provided in the ACR and NEMA standards. PIU and SNR were found to be sensitive to malfunctions in the components of the multileaf collimators. Details of the findings will be presented. Conclusion: The data suggests that ViewRay imaging system has functioned in a consistent and reliable manner. MR imaging from ViewRay 0.35T system complies with the ACR and NEMA recommended acceptance standards

It also includes percent image uniformity (PIU) for T1. The NEMA test is primarily designed to check SNR and PIU. Results: Over the period of six months, all the parameters were maintained within the recommendations provided in the ACR and NEMA standards. PIU and SNR were found to be sensitive to malfunctions in the components of the multileaf collimators. Details of the findings will be presented. Conclusion: The data suggests that ViewRay imaging system has functioned in a consistent and reliable manner. MR imaging from ViewRay 0.35T system complies with the ACR and NEMA recommended acceptance standards.

    Risk, a word that causes a lot of associations in human brains. Many of us don't like risks. Since hundreds of years insurance is the most common way to get rid of the financial consequences when risks convert to damages. This article deals with commercial risks and the possibilities of risk transfer, an important task within the field of risk management. For commercial entities it is very important to transfer risks, threatening the competitiveness or even worse the existence of a company. At the beginning of insurance it was more the less a bet between merchants and rich people. Later on mutual societies were taking place. Today we see a complex insurance industry with insurers, reinsurers, self insuring possibilities via captives and much more. This complex system, with all the different ways to deal with risk transfer requires a professional risk assessment! Risk assessment is based on knowledge about the threatened assets, the likelihood that they will be damaged, the threats and the possibilities to protect these assets. Assets may be tangible or intangible. Assessing risks is not a precise calculation that delivers a result without any doubt. But insurers and insured need a basis to fix a premium, both of them can agree. This contribution will present a system to assess risks and to find the right risk-transfer-premiums.

    Learning organizations use self-evaluation programs to compare their actual performance with their management's expectations and industry standards. In general, self-evaluations identify areas needing improvement. Self-evaluation activities in maintenance departments include self-assessments, management monitoring observations, root cause analyses, event investigations, benchmarking, use of operating experience, self-checking, and problem reporting systems. In Ontario Hydro Nuclear (OHN) we have used almost all forms of self-evaluation with mixed success. However, we did not use self-assessments. With emphasis on excellent maintenance this powerful form of self-evaluation is being introduced to all our plants. Because of its recency and relative inexperience with it, this paper is focused on self-assessment. The paper provides the author's perspective on how a self-assessment program would be evaluated by an independent internal evaluation and what attributes should be in place in order for maintenance departments to succeed in the implementation and successful continuation of the program.

    2007-01-01

    This paper reports a study to assess the palliative care needs of the adult population served by a healthcare provider organization in Northern Ireland from the perspectives of patients, informal carers and healthcare providers. Assessing palliative care need is a key factor for health service planning. Traditionally, palliative care has been associated with end-of-life care and cancer. More recently, the concept has been extended to include care for both cancer and non-cancer populations. Various approaches have been advocated for assessing need, including the exploration of professional provider and user perspectives of need. Semi-structured qualitative interviews were undertaken with a purposive sample of patients and lay carers receiving palliative care services (n = 24). Focus groups were also conducted with multi-professional palliative care providers (n = 52 participants) and face to face interviews were undertaken with key managerial stakeholders in the area (n = 7). The focus groups and interviews concentrated on assessment of palliative care need. All the interviews were transcribed verbatim and analysed using Burnard's framework. Professional providers experienced difficulty in defining the term palliative care. Difficulties in communication and information exchange, and fragmented co-ordination between services were identified. The main areas of need identified by all participants were social and psychological support; financial concerns; and the need for choice and information. All participants considered that there was inequity between palliative care service provision for patients with cancer and non-cancer diseases. All patients, regardless of diagnosis, should be able to access palliative care appropriate to their individual needs. For this to happen in practice, an integrated approach to palliative care is essential. The study methodology confirms the value of developing a comprehensive approach to assessing palliative care need.

    Full Text Available Introduction: Despite the importance of continuity of care and patient engagement, few studies have captured patients’ views on integrated care. This study assesses patient experience in the Integrated Care Pilot in North West London with the aim to help clinicians and policy makers understand patients’ acceptability of integrated care and design future initiatives. Methods: A survey was developed, validated and distributed to 2029 randomly selected practice patients identified as having a care plan. Results: A total of 405 questionnaires were included for analysis. Respondents identified a number of benefits associated with the pilot, including increased patient involvement in decision-making, improved patient-provider relationship, better organisation and access to care, and enhanced inter-professional communication. However, only 22.4% were aware of having a care plan, and of these only 37.9% had a copy of the care plan. Knowledge of care plans was significantly associated with a more positive experience. Conclusions: This study reinforces the view that integrated care can improve quality of care and patient experience. However, care planning was a complex and technically challenging process that occurred more slowly than planned with wide variation in quality and time of recruitment to the pilot, making it difficult to assess the sustainability of benefits.

  10. Uncertainty analysis with a view towards applications in accident consequence assessments

    1985-09-01

    Since the publication of the US-Reactor Safety Study WASH-1400 there has been an increasing interest to develop and apply methods which allow to quantify the uncertainty inherent in probabilistic risk assessments (PRAs) and accident consequence assessments (ACAs) for installations of the nuclear fuel cycle. Research and development in this area is forced by the fact that PRA and ACA are more and more used for comparative, decisive and fact finding studies initiated by industry and regulatory commissions. This report summarizes and reviews some of the main methods and gives some hints to do sensitivity and uncertainty analyses. Some first investigations aiming at the application of the method mentioned above to a submodel of the ACA-code UFOMOD (KfK) are presented. Sensitivity analyses and some uncertainty studies an important submodel of UFOMOD are carried out to identify the relevant parameters for subsequent uncertainty calculations. (orig./HP) [de

    Demographical data are very important in assessing health consequences of the siting of nuclear plants. In addition to a detailed description of the distribution of population living in the neighbourhood of every site, a less definite representation of the population as a whole is needed to assess the consequences of the long-range transport of pollutants within or outside the national boundaries, in order to determine the collective doses according to the concepts of the ICRP recommendations. For this purpose, the census data of the nine countries of the European Community have been collected. They are presented in two forms: either by communes or following a more or less close-meshed grid. The points have been defined by their geographical coordinates. After merging the informations, the demographic data were classified according to the geographical coordinates. One of them is a distribution programme of the population in the meshes of an European grid, some examples of which are shown. (H.K.)

    Sports dietary supplements are available for sale in public places including sports clubs. Although there is uncertainty regarding their safety, many gym members who regularly work out consume them. The present study aimed to identify the approaches and perspectives of the public who work out in gyms and take dietary supplements. It examined how professionals view sports dietary supplement consumption, and how they communicate this issue to gym members. The literature discusses the prevalence of SDS use among athletes, but rarely discusses or compares between the risk perceptions of gym members, trainers, and dietitians, who represent the physically-active general public, regarding SDS. We conducted constructivist qualitative research in semi-structured one-on-one interviews ( n  = 34). We held in-depth interviews ( n  = 20) with a heterogeneous population of adult gym members who take dietary supplements, and ( n  = 14) with dietitians and fitness trainers. The main finding was a gap in risk perception of dietary supplement use between dietitians, gym members and fitness trainers. There was low risk perception among dietary supplements consumers. Trainers believed that benefits of supplement consumption exceeded risk, and therefore they did not convey a message to their clients about risk. In contrast, dietitians interviewed for this study renounced general use of sports dietary supplements and doubted whether trainers had proper nutritional knowledge to support it. Lack of awareness of risks suggests that there is a need for communication on this issue. We recommend that professionals (physicians and dietitians) be present in sports clubs that sell such products in an uncontrolled way.

    "Images of a Healthy Worksite" aims to provide easy access to healthful foods and to reduce sedentarism at the worksite-to prevent weight gain. Formative research for the nutrition intervention component was aimed at gaining a broad understanding of the sociocultural role of food and eating among workers and worker perspectives on socially feasible and culturally acceptable environmental intervention strategies. Using an adapted PRECEDE health planning model, we conducted ecological, educational, environmental, and administrative assessments at the worksite. Through 15 in-depth interviews, five focus groups, and community mapping at two sites with 79 administrators, managers, workers, and food service personnel (51% men, 82% white), we assessed workers' perspectives on physical, sociocultural, economic, and policy environments. Data were coded for predisposing, enabling, and reinforcing factors related to intervention strategies in vending, cafeteria, catering, and informal food environments. After classification for reach, intensity, and sustainability, objectives and evaluation plans were developed for each highly ranked strategy. Key sociocultural factors affecting food and eating included: stress-related eating in a downsizing workplace, enthusiasm for employer-sponsored weight gain prevention efforts that respect personal privacy, and the consequences of organizational culture on worker access to the food and eating environment. Workers supported healthier cafeteria and catering options, bringing healthful foods closer, and labeling of healthful options. We provide a practical and systematic approach to formative research and assess the interrelatedness of the physical, policy, economic, and sociocultural factors that affect environmental worksite interventions to prevent weight gain among employees.

    There is a need for studies to assess domestic violence (DV) shelter workers views about brief HIV prevention interventions for shelter residents to improve these workers' provision of HIV prevention interventions to shelter residents. This mixed methods study assessed DV shelter workers' views about the following: (a) the need for and appropriateness of HIV prevention services within DV shelters, (b) the utility (i.e., acceptability, systems support, understanding, and feasibility) of an HIV Risk Assessment and Safety Plan (HIV RASP) for women in DV shelters, and (c) suggested changes to or concerns about using the HIV RASP. Workers from DV shelters located in the 10 states in the United States with the highest rates of HIV reviewed the HIV RASP and answered survey questions about it including the Usage Rating Profile-Intervention (URP-I) Questionnaire and two open-ended questions. Although workers felt it was appropriate to provide HIV prevention interventions within DV shelters, only 23% reported that HIV prevention interventions had ever been implemented at their shelter and only 42% had provided residents with educational brochures about HIV prevention. Workers generally agreed that the HIV RASP was acceptable, understandable, and feasible. They somewhat disagreed about their ability to implement the tool independently. Findings suggest that little progress has been made in engaging DV shelter workers in HIV prevention efforts for residents during the past decade and reveal ways to improve the HIV RASP and overcome barriers to implementing it. The study findings may be used to help reduce gaps between the science and practice of HIV prevention for abused women.

  17. Economic assessment of nuclear energy from systems theory's point of view

    1976-01-01

    A report is given on how systems theory can be incorporated in nuclear energy and in which manner it can be applied. As opposed to previous considerations in which the development of nuclear energy in the form of cost effects of the energy produced in a nuclear power plant was assessed and the power plant was considered as insular plant, today this is replaced by the investigation of the individual nuclear power plants by a system of several such plants. The economy criterium of such a system is considered as the quotient of 'discounted' expenditure and discounted electro-energy production. The total discounted electricity generation by the nuclear power plant system also includes the energy production of new nuclear power plants to come and allows their special economy assessment. This method eliminates the question of the buying and selling price of plutonium and the interest payment of the expenditure for using Pn fuel. The discount programme, the systems costs, concessions in discounting, the minimization of the consumption, and the plutonium valuation are individually dealt with in detail. The solution to the linear three-interval programme is given in the appendix. (HR/LH) [de

    The purpose of this study is to analyze the perception of the content of health technology assessment (HTA) among health professionals applying for a state grant of DKK 10 million. A total of 113 applications were received and analyzed. When conducting the analysis, it was assumed that the applicants' maximum five-page project description would reflect: a) the applicants' perception of what an HTA is; b) how the assessment was to be conducted; and c) what the results were going to be used for. More than 40% of all applications focused on treatment; in 51% only one or two professional groups were to be involved (thus interdisciplinarity was questionable); only 22% of the HTA cases were intended to form the basis for political/administrative decisions; in general, the HTAs were planned far less comprehensively than was relevant; 76% of the projects did not include a formal synthesis phase; 41% intended to use diffusion as the only method for publication of the HTA result. The analysis reveals several areas where DIHTA has to make an effort in order to secure that HTA in fact constitutes a comprehensive and well-documented basis for decision making. These areas concern the following topics: multidisciplinarity, the objective of HTA, comprehensiveness, the synthesis phase, and publication and utilization of the HTA result.

    The relationship between alcohol consumption and sexual crime appears to be unquestionable. However, the mechanisms that lead to violence and aggression under the influence of alcohol are not entirely understood in this group of offenders. The aim of this paper was to attempt answering the question: what are the features characterizing sexual offenders declaring alcohol abuse. The research material consisted of 180 forensic psychiatric- sexology assessments issued by experts from Outpatient Psychiatric Clinic in 10 Military Hospital Clinic in Bydgoszcz between 2004 to 2012. A specially designed questionnaire titled "Charter of Diagnosis of Factors Determining Criminal Sexual Activity" has been used. Relevant statistical dependences were observed. The obtained results show that, a alcohol abuse has a sexual criminogenic effect especially in the coincidence that there are sustainable personality abnormalities and organic CNS damage. The conducted study prove that the sexual perpetrators who abuse alcohol have a poor level of social functioning and brought up in dysfunction families having alcoholic problems. © 2015 MEDPRESS.

    Frontal chest radiographs can be misleading in the evaluation of central venous catheter placement. Lateral chest radiographs were obtained, in addition to the standard frontal radiographs, in 25 young children. In five (20%) of the children, the catheters were found to be malpositioned, and the frontal radiograph showed evidence of the abnormality in all five. The lateral radiographs also showed evidence of the abnormality in all five children; however, in three of the five, the lateral radiographs provided additional, more specific, diagnostic information. The lateral chest radiographs also demonstrated satisfactory catheter positioning in three other children in whom the frontal radiographs suggested abnormal positioning. Accurate assessment of catheter position was possible in all patients using both frontal and lateral chest radiographs. Injection of contrast material was not necessary to locate malpositioned catheters. Lateral radiographs are recommended whenever an abnormal catheter position is suspected clinically or from findings on the routine frontal radiograph. (orig.)

    Field work has been concentrated at the Altnabreac Research Site on north-east Scotland, where three deep boreholes to approximately 300 m and 24 shallow boreholes to approximately 40 m were drilled. The movement of groundwater within 300 m of the surface was investigated using a specially developed straddle packer system. Geochemical studies have demonstrated that most groundwater is dominated by recent recharge but one borehole yielded water with an age of around 10 4 years. Geophysical borehole logging has shown that the full wave train sonic logs and the acoustic logs show most promise for the assessment of crystalline rocks. In the laboratory the interaction of rocks and groundwater at the temperature/pressure conditions to be expected in a repository has established the geochemical environment to which waste canisters and backfill materials would be subjected. Other generic studies reported include the characterization of geotechnical properties of rocks at elevated temperatures and pressures, the development of a new cross-hole sinusoidal pressure test for the measurement of hydraulic properties and the use of thermal infra-red imagery to detect groundwater discharge zones

    2002-01-01

    In the relatively short time since their commercial introduction in 1996, genetically modified (GM) crops have been rapidly adopted in the United States GM crops are regulated through a coordinated framework developed in 1992 and administered by three agencies-the US Department of Agriculture (USDA) that ensures the products are safe to grow, the Environmental Protection Agency (EPA) that ensures the products are safe for the environment, and the Food and Drug Administration (FDA) that ensures the products are safe to eat. Rigorous food and environmental safety assessments must be completed before GM crops can be commercialized. Fifty-one products have been reviewed by the FDA, including several varieties of corn, soybeans, canola, cotton, rice, sugar beets, potatoes, tomatoes, squash, papaya, and flax. Because FDA considers these crops "substantially equivalent" to their conventional counterparts, no special labeling is required for GM crops in the United States and they are managed as commodities with no segregation or identity preservation. GM crops have thus made their way through commodity distribution channels into thousands of ingredients used in processed foods. It has been estimated that 70% to 85% of processed foods on supermarket shelves in the United States today contain one or more ingredients potentially derived from GM crops. The food industry and retail industry have been monitoring the opinions of their consumers on the GM issue for the past several years. Numerous independent groups have also surveyed consumer concerns about GM foods. The results of these surveys are shared and discussed here.

    Fraunholz, I.B.; Gerstenhauer, A.; Boettcher, H.D.

    2005-01-01

    Background and Purpose: As treatment of keloids is mainly a cosmetic indication, the authors investigated, beyond the recurrence rate, the patients' satisfaction with the result and its correlation with objective medical findings. Patients and Methods: 83 keloids of 66 patients had been irradiated after excision by a uniform protocol with 4 x 5 Gy (strontium-90 [ 90 Sr] surface applicator). A questionnaire was developed and sent out in which, above all, the satisfaction with the therapeutic and cosmetic outcome was obtained. These results were correlated with objective parameters and medical findings which were ascertained during an extra follow-up examination. Results: Among 18 of the 41 patients (44%), who had answered the questionnaire, 19 of the 53 keloids treated (36%) had relapsed. 61% of the patients were extremely or mainly satisfied with the therapeutic outcome, 51% extremely or mainly satisfied with the cosmetic outcome. The relief from former keloid-caused symptoms (therapeutic outcome: p=0.0005; cosmetic outcome: p=0.0011), the ear as keloid localization (p=0.0008 and p=0.0197), and male gender (therapeutic outcome: p=0.0423) were significantly associated with higher satisfaction. The recurrence rate as well as the extent of radiation side effects had no significant influence on patients' assessment. Conclusion: Cosmetic aspects like the dermal side effects and the patients' satisfaction should be taken into account when evaluating the results of radiotherapy in keloids. (orig.)

    This article assesses parental confidence and current behavioral techniques used by mostly African American caregivers of young children in an urban Southeastern setting, including their use and attitudes toward corporal punishment (CP). Two hundred and fifty parental participants of children aged 18 months to 5 years completed a survey on factors affecting their behavioral management and views on CP. Statistical analysis included χ 2 test and logistic regression with confidence interval significance determined at P <.05. Significant associations of CP usage were found in parents who were themselves exposed to CP and parental level of frustration with child disobedience. A total of 40.2% of respondents answered that they had not received any discipline strategies from pediatricians and 47.6% were interested in receiving more behavioral strategies. Clear opportunities exist for pediatricians to provide information on evidence-based disciplinary techniques, and these discussions may be facilitated through the creation of a No Hit Zone program in the pediatric practice.

    This paper discusses the AECB practices in assessing maintenance activities at one four unit CANDU nuclear plant.-it outlines the authority of the AECB in enforcing the licence condition concerned with maintenance, and how this is interpreted by AECB site staff to measure and report maintenance activities. The AECB staff attaches great importance to proper maintenance as it affects safe operation. Programs used by the licensee staff to identify safety important components, or to predict degradations and failures are of particular interest. In our experience, the application of such programs has been generally good. However, their integration into an overall maintenance scheme can be improved, and the possibilities of integration are not well understood. This paper includes examples of such integration to illustrate our views and to highlight the resultant benefits that AECB staff believes are possible. (author)

    Full Text Available Multistorey buildings typically include stratified legal interests which provide entitlements to a community of owners to lawfully possess private properties and use communal and public properties. The spatial arrangements of these legal interests are often defined by multiplexing cognitively outlined spaces and physical elements of a building. In order to support 3D digital management and communication of legal arrangements of properties, a number of spatial data models have been recently developed in Geographic Information Systems (GIS and Building Information Modelling (BIM domains. While some data models, such as CityGML, IndoorGML or IFC, provide a merely physical representation of the built environment, others, e.g., LADM, mainly rely on legal data elements to support a purely legal view of multistorey buildings. More recently, spatial data models integrating legal and physical notions of multistorey buildings have been proposed to overcome issues associated with purely legal models and purely physical ones. In previous investigations, it has been found that the 3D digital data environment of BIM has the flexibility to utilize either only physical elements or only legal spaces, or an integrated view of both legal spaces and physical elements to represent spatial arrangements of stratified legal interests. In this article, the performance of these three distinct BIM-based representations of legal interests defined inside multistorey buildings is assessed in the context of the Victorian jurisdiction of Australia. The assessment metrics are a number of objects and geometry batches, visualization speed in terms of frame rate, query time, modelling legal boundaries, and visual communication of legal boundaries.

    Full Text Available Sensor miniaturisation, improved battery technology and the availability of low-cost yet advanced Unmanned Aerial Vehicles (UAV have provided new opportunities for environmental remote sensing. The UAV provides a platform for close-range aerial photography. Detailed imagery captured from micro-UAV can produce dense point clouds using multi-view stereopsis (MVS techniques combining photogrammetry and computer vision. This study applies MVS techniques to imagery acquired from a multi-rotor micro-UAV of a natural coastal site in southeastern Tasmania, Australia. A very dense point cloud ( < 1–3 cm point spacing is produced in an arbitrary coordinate system using full resolution imagery, whereas other studies usually downsample the original imagery. The point cloud is sparse in areas of complex vegetation and where surfaces have a homogeneous texture. Ground control points collected with Differential Global Positioning System (DGPS are identified and used for georeferencing via a Helmert transformation. This study compared georeferenced point clouds to a Total Station survey in order to assess and quantify their geometric accuracy. The results indicate that a georeferenced point cloud accurate to 25–40 mm can be obtained from imagery acquired from 50 m. UAV-based image capture provides the spatial and temporal resolution required to map and monitor natural landscapes. This paper assesses the accuracy of the generated point clouds based on field survey points. Based on our key findings we conclude that sub-decimetre terrain change (in this case coastal erosion can be monitored.

    Small islands have the attention of the international community because they are territories with unique features, and a pressing need for the enhancement of sustainability. Strategic Environmental Assessment (SEA) has characteristics that may promote the development and improvement of sustainability in these territories: (i) changing the mind-set, and the decision-making and institutional paradigm, (ii) facilitating cooperation and coordination between different stakeholders, and (iii) providing a framework for good governance and community empowerment. The scientific literature suggests that there may be a need for context-specific SEA in these territories. However, SEA studies often do not incorporate local contextual information, including intuitive knowledge and sense of place. Therefore, there is a possible gap between what is found in the literature and what local communities think, including different stakeholders and experts. Hence, the main goal of this research was to gain an insight into the views and perspectives of small islands SEA experts about issues related to SEA in European small islands, including context-specific approaches, as well as the contribution of SEA for sustainability in these territories. To achieve the research aim, exploratory research using a questionnaire-based survey was designed, aimed at experts on SEA in European small islands. Findings showed regional cooperation networks may have a fundamental role when developing SEA-specific approaches in these territories. This is because SEA-specific approaches encourage a joint effort among islands within one region to improve SEA capacity-building, develop and share a baseline information system, and to share and exchange resources, overall. Also, guidelines are preferred among experts over more legal frameworks and regulations. Finally, the research showed that experts view SEA as a way to enhance sustainability in small islands. This study highlights the importance of integrating

    Google Street View provides a valuable and efficient alternative to observe the physical environment compared to on-site fieldwork. However, studies on the use, reliability and validity of Google Street View in a cycling-to-school context are lacking. We aimed to study the intra-, inter-rater reliability and criterion validity of EGA-Cycling (Environmental Google Street View Based Audit - Cycling to school), a newly developed audit using Google Street View to assess the physical environment along cycling routes to school. Parents (n = 52) of 11-to-12-year old Flemish children, who mostly cycled to school, completed a questionnaire and identified their child's cycling route to school on a street map. Fifty cycling routes of 11-to-12-year olds were identified and physical environmental characteristics along the identified routes were rated with EGA-Cycling (5 subscales; 37 items), based on Google Street View. To assess reliability, two researchers performed the audit. Criterion validity of the audit was examined by comparing the ratings based on Google Street View with ratings through on-site assessments. Intra-rater reliability was high (kappa range 0.47-1.00). Large variations in the inter-rater reliability (kappa range -0.03-1.00) and criterion validity scores (kappa range -0.06-1.00) were reported, with acceptable inter-rater reliability values for 43% of all items and acceptable criterion validity for 54% of all items. EGA-Cycling can be used to assess physical environmental characteristics along cycling routes to school. However, to assess the micro-environment specifically related to cycling, on-site assessments have to be added.

  12. Remote viewing.

    Remote viewing is the supposed faculty which enables a percipient, sited in a closed room, to describe the perceptions of a remote agent visiting an unknown target site. To provide convincing demonstration of such a faculty poses a range of experimental and practical problems, especially if feedback to the percipient is allowed after each trial. The precautions needed are elaborate and troublesome; many potential loopholes have to be plugged and there will be strong temptations to relax standards, requiring exceptional discipline and dedication by the experimenters. Most reports of remote viewing experiments are rather superficial and do not permit assessment of the experimental procedures with confidence; in many cases there is clear evidence of particular loopholes left unclosed. Any serious appraisal of the evidence would have to go beyond the reports. Meanwhile the published evidence is far from compelling, and certainly insufficient to justify overthrow of well-established scientific principles.

    We present our views on validation. We consider that validation is slightly different for general models and specific models. We stress the importance of presenting for review the case for (or against) a model. We outline a formal framework for validation, which helps to ensure that all the issues are addressed. Our framework includes calibration, testing predictions, comparison with alternative models, which we consider particularly important, analysis of discrepancies, presentation, consideration of implications and suggested improved experiments. We illustrate the approach by application to an INTRAVAL test case based on laboratory experiments. Three models were considered: a simple model that included the effects of advection, dispersion and equilibrium sorption, a model that also included the effects of rock-matrix diffusion, and a model with kinetic sorption. We show that the model with rock-matrix diffusion is the only one to provide a good description of the data. We stress the implications of extrapolating to larger length and time scales for repository performance assessments. (author)

    There are mounting calls for robust, critical evaluation of the impact of patient and public involvement (PPI) in health research. However, questions remain about how to assess its impact, and whether it should be assessed at all. The debate has thus far been dominated by professionals. To explore the views of PPI contributors involved in health research regarding the impact of PPI on research, whether and how it should be assessed. Qualitative interview study. Thirty-eight PPI contributors involved in health research across the UK. Participants felt that PPI has a beneficial impact on health research. They described various impactful roles, which we conceptualize as the 'expert in lived experience', the 'creative outsider', the 'free challenger', the 'bridger', the 'motivator' and the 'passive presence'. Participants generally supported assessing the impact of PPI, while acknowledging the challenges and concerns about the appropriateness and feasibility of measurement. They expressed a range of views about what impacts should be assessed, by whom and how. Individual feedback on impact was seen as an important driver of improved impact and motivation to stay involved. While there appears to be widespread support for PPI impact assessment among PPI contributors, their views on what to assess and how are diverse. PPI contributors should be involved as equal partners in debates and decisions about these issues. Individual feedback on impact may increase PPI contributors' potential impact and their motivation to stay involved. © 2016 The Authors. Health Expectations Published by John Wiley & Sons Ltd.

    To assess parents' perspectives of their home environments to establish the validity of scores from the Behavior and Attitudes Questionnaire for Healthy Habits (BAQ-HH). In the present descriptive study, we surveyed a cross-sectional sample of parents of pre-school children. Questionnaire items developed in an iterative process with community-based programming addressed parents' knowledge/awareness, attitudes/concerns and behaviours about healthy foods and physical activity habits with 6-point rating scales. Exploratory and confirmatory factor analyses were used to psychometrically evaluate scores from the scales. English and Spanish versions of the BAQ-HH were administered at parent-teacher conferences for pre-school children at ten Head Start centres across a five-county agency in autumn 2010. From 672 families with pre-school children, 532 parents provided responses to the BAQ-HH (79 % response rate). The majority was female (83 %), Hispanic (66 %) or white (16 %), and ages ranged from 20 to 39 years (85 %). Exploratory and confirmatory analyses revealed a knowledge scale (seven items), an attitude scale (four items) and three behaviour subscales (three items each). Correlations were identified between parents' perceptions of home activities and reports of children's habits. Differences were identified by gender and ethnicity groupings. As a first step in psychometric testing, the dimensionality of each of the three scales (Knowledge, Attitudes and Behaviours) was identified and scale scores were related to other indicators of child behaviours and parents' demographic characteristics. This questionnaire offers a method to measure parents' views to inform planning and monitoring of obesity-prevention education programmes.

    Online videos are among the most common resources for case preparation. Using crowd sourcing, we evaluated the relationship between operative quality and viewing characteristics of online laparoscopic cholecystectomy videos. We edited 160 online videos of laparoscopic cholecystectomy to 60 seconds or less. Crowd workers (CW) rated videos using Global Objective Assessment of Laparoscopic Skills (GOALS), the critical view of safety (CVS) criteria, and assigned overall pass/fail ratings if CVS was achieved; linear mixed effects models derived average ratings. Views, likes, dislikes, subscribers, and country were recorded for subset analysis of YouTube videos. Spearman correlation coefficient (SCC) assessed correlation between performance measures. One video (0.06%) achieved a passing CVS score of ≥5; 23%, ≥4; 44%, ≥3; 79%, ≥2; and 100% ≥1. Pass/fail ratings correlated to CVS, SCC 0.95 (p quality. The average CVS and GOALS scores were no different for videos with >20,000 views (22%) compared with those with online surgical videos of LC. Favorable characteristics, such as number of views or likes, do not translate to higher quality. Copyright © 2017 American College of Surgeons. Published by Elsevier Inc. All rights reserved.

    The indices of asymmetry enable estimation and long-term control of mandibular growth. The aim of this study is to present 3 indices which have been used in case of atypical growth of left and right part of mandible. Radiograms in PA projection, panoramic views and CT scans of patient KK, aged 24, were used in this study. Comparative measurements and calculations of Habets index, Kjellberg index and own, angular asymmetry index (AAI) were performed. The analysis of left mandibular condyle and ramus showed severe anatomical deviations. Comparative evaluation of panoramic views allowed to observe progression of lesions responsible for asymmetry. Indices of asymmetry are objective method of mandibular growth estimation. Because of different gauge points and different way of calculation, presented indices: Habets, Kjellberg and AAI are incomparable, but each of them may be used as sufficient diagnostic tool. The angular asymmetry index (AAI) seems to be the simplest and quickest of all three. (author)

    Since the beginning of Cone Beam Computed Tomography (CBCT) in dento-maxillo-facial radiology, many CBCT devices with different technical aspects and characteristics were produced. Technical variations between CBCT and acquisition settings could involve image quality differences. In order to compare the performance of three limited field-of-view CBCT devices, an objective and subjective evaluation of image quality was carried out using an ex-vivo phantom, which combines both diagnostic and technical features. A significant difference in image quality was found between the five acquisition protocols of the study. (author) [fr

    1991-01-01

    Children's peer assessments of aggressive and withdrawn behavior are fundamentally related to developmental changes in their understanding of others. This article synthesizes research relevant to the thesis that peer assessments are dependent on children's ability both to recall the previous behavior of their peers and to predict their likely future behavior. Social schema theory, borrowed from adult social psychology, is highly relevant to such recall and prediction. Age differences, affective biases, and gender roles may color children's assessments of their peers' social behavior. Such influences should be taken into account when conceptualizing interventions aimed at enhancing children's peer status, and in measuring the success of these interventions. PMID:1958647

    The food choices in childhood have high a probability of being carried through into their adulthood life, which then contributes to the risk of many non-communicable diseases. Therefore, there is a need to gather some information about children's views on foods which may influence their food choices for planning a related dietary intervention or programme. This paper aimed to explore the views of children on foods and the types of foods which are usually consumed by children under four food groups (snacks, fast foods, cereals and cereal products; and milk and dairy products) by using focus group discussions. A total of 33 school children aged 7-9 years old from Selangor and Kuala Lumpur participated in the focus groups. Focus groups were audio-taped, transcribed and analyzed according to the listed themes. The outcomes show that the children usually consumed snacks such as white bread with spread or as a sandwich, local cakes, fruits such as papaya, mango and watermelon, biscuits or cookies, tea, chocolate drink and instant noodles. Their choices of fast foods included pizza, burgers, French fries and fried chicken. For cereal products, they usually consumed rice, bread and ready-to-eat cereals. Finally, their choices of dairy products included milk, cheese and yogurt. The reasons for the food liking were taste, nutritional value and the characteristics of food. The outcome of this study may provide additional information on the food choices among Malaysian children, especially in urban areas with regard to the food groups which have shown to have a relationship with the risk of childhood obesity.

    Full Text Available Directional effects introduce a variability in reflectance and vegetation index determination, especially when large field-of-view sensors are used (e.g., Moderate Resolution Imaging Spectroradiometer - MODIS. In this study, we evaluated directional effects on MODIS reflectance and four vegetation indices (Normalized Difference Vegetation Index - NDVI; Enhanced Vegetation Index - EVI; Normalized Difference Water Index - NDWI1640 and NDWI2120 with the soybean development in two growing seasons (2004-2005 and 2005-2006. To keep the reproductive stage for a given cultivar as a constant factor while varying viewing geometry, pairs of images obtained in close dates and opposite view angles were analyzed. By using a non-parametric statistics with bootstrapping and by normalizing these indices for angular differences among viewing directions, their sensitivities to directional effects were studied. Results showed that the variation in MODIS reflectance between consecutive phenological stages was generally smaller than that resultant from viewing geometry for closed canopies. The contrary was observed for incomplete canopies. The reflectance of the first seven MODIS bands was higher in the backscattering. Except for the EVI, the other vegetation indices had larger values in the forward scattering direction. Directional effects decreased with canopy closure. The NDVI was lesser affected by directional effects than the other indices, presenting the smallest differences between viewing directions for fixed phenological stages.Efeitos direcionais introduzem variabilidade na reflectância e na determinação de índices de vegetação, especialmente quando sensores de amplo campo de visada são usados (p.ex., Moderate Resolution Imaging Spectroradiometer - MODIS.

    Being involved in motor vehicle collisions is the leading cause of death in 1- to 34-year-olds, and risk is particularly high in young adults. The Useful Field of View (UFOV) task, a cognitive measure of processing speed, divided attention, and selective attention, has been shown to be predictive of motor vehicle collisions in older adults, but its use as a predictor of driving performance in a young adult population has not been investigated. The present study examined whether UFOV was a predictive measure of motor vehicle collisions in a driving simulator in a young adult population. The 3-subtest version of UFOV (lower scores measured in milliseconds indicate better performance) was administered to 60 college students. Participants also completed an 11-mile simulated drive to provide driving performance metrics. Findings suggested that subtests 1 and 2 suffered from a ceiling effect. UFOV subtest 3 significantly predicted collisions in the simulated drive. Each 30 ms slower on the subtest was associated with nearly a 10% increase in the risk of a simulated collision. Post hoc analyses revealed a small partially mediating effect of subtest 3 on the relationship between driving experience and collisions. The selective attention component of UFOV subtest 3 may be a predictive measure of crash involvement in a young adult population. Improvements in selective attention may be the underlying mechanism in how driving experience improves driving performance.

    The ARAMIS methodology was developed in an European project co-funded in the fifth Framework Programme of the European Commission with the objective to answer the specific requirements of the SEVESO II directive. It offers an alternative to purely deterministic and probabilistic approaches to risk assessment of process plants. It also answers the needs of the various stakeholders interested by the results of the risk assessment for land use or emergency planning, enforcement or, more generally, public decision-making. The methodology is divided into the following major steps: identification of major accident hazards (MIMAH), identification of the safety barriers and assessment of their performances, evaluation of safety management efficiency to barrier reliability, identification of reference accident scenarios (MIRAS), assessment and mapping of the risk severity of reference scenarios and of the vulnerability of the plant surroundings. The methodology was tested during five case studies, which provided useful information about the applicability of the method and, by identifying the most sensitive parts of it opened way to new research activity for an improved industrial safety

    Learning organizations use self-evaluation programs to compare their actual performance with their management's expectations and industry standards. In general, self-evaluations identify areas needing improvement. Self-evaluation activities in maintenance departments include self-assessments, management monitoring observations, root cause analyses, event investigations, benchmarking, use of operating experience, self-checking, and problem reporting systems. In Ontario Hydro Nuclear (OHN) we have used almost all forms of self-evaluation with mixed success. However, we did not use self-assessments. With emphasis on excellent maintenance this powerful form of self-evaluation is being introduced to all our plants. Because of its recency and relative inexperience with it, this paper is focused on self-assessment. The paper provides the author's perspective on how a self-assessment program would be evaluated by an independent internal evaluation and what attributes should be in place in order for maintenance departments to succeed in the implementation and successful continuation of the program.

    Patient satisfaction is an important measure of health care quality. Patients' views have seldom been considered in the construction of measures addressing satisfaction with inpatient facilities in psychiatry. The Views on Inpatient Care - VOICE - is a first service-user generated outcome measure relying solely on their perceptions of acute care, representing a valuable indicator of service users' perceived quality of care. The present study aimed to contribute to the validation of the Portuguese version of VOICE. The questionnaire was translated into Portuguese and applied to a sample of eighty-five female inpatients of a psychiatric institution. Data analysis focused on assessing reliability and exploring the impact of demographic and clinical variables on participants' satisfaction. Internal consistency of the questionnaire was high (α = 0.87). Participants' age and marital status were associated with differences in scores, with older patients and patients who were married or involved in a close relationship presenting higher satisfaction levels. The questionnaire demonstrated good internal consistency and acceptability, as well as construct validity. Further studies should expand the analysis of the psychometric properties of this measure e.g., test-retest reliability. The Portuguese version of VOICE is a promising tool to assess service users' perceptions of inpatient psychiatric care in Portugal.

    The most important parameter that reflects the balance between oxygen supply and demand in tissues is the mitochondrial NADH redox state that could be monitored In vivo. Nevertheless single parameter monitoring is limited in the interpretation capacity of the very complicated pathophysiological events, therefore three more parameters were added to the NADH and the multiparametric monitoring system was used in experimental and clinical studies. In our previous paper1 we described the CritiView (CRV1) including a fiber optic probe that monitor four physiological parameters in real time. In the new model (CRV3) several factors such as UV safety, size and price of the device were improved significantly. The CRV3 enable to monitor the various parameters in three different locations in the tissue thus increasing the reliability of the data due to the better statistics. The connection between the device and the monitored tissue could be done by various types of probes. The main probe that was tested also in clinical studies was a special 3 points probe that includes 9 optical fibers (3 in each point) that was embedded in a three way Foley catheter. This catheter enabled the monitoring of urethral wall vitality as an indicator of the development of body metabolic emergency state. The three point probe was tested in the brain exposed to the lack of oxygen (Anoxia, Hypoxia or Ischemia). A decrease in blood oxygenation and a large increase in mitochondrial NADH fluorescence were recorded. The microcirculatory blood flow increased during anoxia and hypoxia and decreased significantly under ischemia.

    A new view of Ecuador's complex geodynamics has been developed in the course of modeling seismic source zones for probabilistic seismic hazard analysis. This study focuses on two aspects of the plates' interaction at a continental scale: (a) age-related differences in rheology between Farallon and Nazca plates—marked by the Grijalva rifted margin and its inland projection—as they subduct underneath central Ecuador, and (b) the rapidly changing convergence obliquity resulting from the convex shape of the South American northwestern continental margin. Both conditions satisfactorily explain several characteristics of the observed seismicity and of the interseismic coupling. Intermediate-depth seismicity reveals a severe flexure in the Farallon slab as it dips and contorts at depth, originating the El Puyo seismic cluster. The two slabs position and geometry below continental Ecuador also correlate with surface expressions observable in the local and regional geology and tectonics. The interseismic coupling is weak and shallow south of the Grijalva rifted margin and increases northward, with a heterogeneous pattern locally associated to the Carnegie ridge subduction. High convergence obliquity is responsible for the North Andean Block northeastward movement along localized fault systems. The Cosanga and Pallatanga fault segments of the North Andean Block-South American boundary concentrate most of the seismic moment release in continental Ecuador. Other inner block faults located along the western border of the inter-Andean Depression also show a high rate of moderate-size earthquake production. Finally, a total of 19 seismic source zones were modeled in accordance with the proposed geodynamic and neotectonic scheme.

    Echocardiography (echo) is a skilled technical procedure that depends on the experience of the operator. The aim of this paper is to reduce user variability in data acquisition by automatically computing a score of echo quality for operator feedback. To do this, a deep convolutional neural network model, trained on a large set of samples, was developed for scoring apical four-chamber (A4C) echo. In this paper, 6,916 end-systolic echo images were manually studied by an expert cardiologist and were assigned a score between 0 (not acceptable) and 5 (excellent). The images were divided into two independent training-validation and test sets. The network architecture and its parameters were based on the stochastic approach of the particle swarm optimization on the training-validation data. The mean absolute error between the scores from the ultimately trained model and the expert's manual scores was 0.71 ± 0.58. The reported error was comparable to the measured intra-rater reliability. The learned features of the network were visually interpretable and could be mapped to the anatomy of the heart in the A4C echo, giving confidence in the training result. The computation time for the proposed network architecture, running on a graphics processing unit, was less than 10 ms per frame, sufficient for real-time deployment. The proposed approach has the potential to facilitate the widespread use of echo at the point-of-care and enable early and timely diagnosis and treatment. Finally, the approach did not use any specific assumptions about the A4C echo, so it could be generalizable to other standard echo views.

    Objective: To ascertain people's views regarding disclosure of cancer diagnosis and whether they would like to share this information with their family. The study also looked at whether if their parents were diagnosed to be suffering from cancer, would they like this information to be communicated to them. Results: The total number of persons surveyed were 520. Fifteen persons refused to participate in the survey, hence they were excluded and 505 respondents 299 male and 206 female were analyzed. Ages of the respondents were between 18 to 80 years. The study population belonged to different socio-economic groups in the society. Three hundred ninety-one (77.4%) responded positively that they would like to know if they ever suffer from cancer, while 112 (22.1%) said No and 2 (0.39%) said it doesn't matter. Three hundred seventeen (62.7%) wanted their family to be informed while 187 (37.%) said No and the attitude of 1 (0.19%) was Indifferent. One hundred seventy (33.6% responded positively that if their parents were diagnosed to be suffering from cancer they should be told about it, whereas 334 (66.1%) did not wish their parents to be informed and 1 (0.19%) was indecisive. All those who were indifferent were elderly, above the age of seventy yeas. Majority 326 (82.6%) who wanted to know the cancer diagnoses were literate and interestingly 57 (50.8%) who didn't wish to be informed were also literate. Conclusions: Most of the people in the survey 391 (77.4%) wanted to now the diagnosis, if they ever suffered from cancer. Again 317 (62.7%) wished this to be disclosed to their family. Only a small percentage 170 (33.6%), wanted to tell the bad news of cancer diagnosis to their parents if they ever suffered. (author)

    Full Text Available Genome-wide association studies (GWAS have been fruitful in identifying disease susceptibility loci for common and complex diseases. A remaining question is whether we can quantify individual disease risk based on genotype data, in order to facilitate personalized prevention and treatment for complex diseases. Previous studies have typically failed to achieve satisfactory performance, primarily due to the use of only a limited number of confirmed susceptibility loci. Here we propose that sophisticated machine-learning approaches with a large ensemble of markers may improve the performance of disease risk assessment. We applied a Support Vector Machine (SVM algorithm on a GWAS dataset generated on the Affymetrix genotyping platform for type 1 diabetes (T1D and optimized a risk assessment model with hundreds of markers. We subsequently tested this model on an independent Illumina-genotyped dataset with imputed genotypes (1,008 cases and 1,000 controls, as well as a separate Affymetrix-genotyped dataset (1,529 cases and 1,458 controls, resulting in area under ROC curve (AUC of approximately 0.84 in both datasets. In contrast, poor performance was achieved when limited to dozens of known susceptibility loci in the SVM model or logistic regression model. Our study suggests that improved disease risk assessment can be achieved by using algorithms that take into account interactions between a large ensemble of markers. We are optimistic that genotype-based disease risk assessment may be feasible for diseases where a notable proportion of the risk has already been captured by SNP arrays.

    Full Text Available Production of electric power in Poland bases on burning brown and hard coal. Currently over 90 % of electricity originates from this source. Generating electric power, like many other human activities, inevitably involves production of wastes. Considering the previous trends of these waste materials utilisation, one should analyse also potential use of biogenic components which they contain as fertilizers. The main objective of conducted investigations was an assessment of potential application of selected waste materials, i.e. fly ashes from production, fly ashes from the landfill site and slag sand from “KRAKÓW S.A.” heat and power plant for agricultural and environmental purposes. The assessment was made on the basis of analyses of the following physical and chemical properties of studied materials: pH, granulometric composition determined by Bouyoucose-Casagrande method in Prószyński’s modification, total alkalinity, total nitrogen content assessed by means of Kjeldahl’s method, organic carbon by Tiurin’s method, total contents of trace elements and the content of available forms of trace elements soluble in 1 mol · dm-3 HCl solution. On the basis of conducted laboratory analyses it should be stated that the amounts of heavy metals determined in the studied materials did not exceed the content allowable for waste materials designed for soil liming. The analysed materials reveal physical and chemical properties which do not exclude their potential application for soil liming. In this respect, fly ash from production seems the best. However, it contains about twice lower amounts of CaO in comparison with other calcium fertilizers available on the market.

    In upland environments, quantifying soil loss through erosion processes at a high resolution can be time consuming, costly and logistically difficult. In this pilot study 'A cost effective framework for monitoring soil erosion in England and Wales', funded by the UK Department for Environment, Food and Rural Affairs (Defra), we evaluate the use of annually repeated ground-based photography surveys, processed using structure-from-motion and multi-view stereo (SfM-MVS) 3-D reconstruction software (Agisoft Photoscan). The aim is to enable efficient but detailed site-scale studies of erosion forms in inaccessible UK upland environments, in order to quantify dynamic processes, such as erosion and mass movement. The evaluation of the SfM-MVS technique is particularly relevant in upland landscapes, where the remoteness and inaccessibility of field sites may render some of the more established survey techniques impractical. We present results from 5 upland sites across the UK, acquired over a 2-year period. Erosion features of varying width (3 m to 35 m) and length (20 m to 60 m), representing a range of spatial scales (from 100 m2 to 1000 m2) were surveyed, in upland habitats including bogs, peatland, upland grassland and moorland. For each feature, around 150 to 600 ground-based photographs were taken at oblique angles over a 10 to 20 minute period, using an uncalibrated Canon 600D SLR camera with a 28 mm lens (focal length set to infinity). Camera settings varied based upon light conditions (exposure 100-400 ISO, aperture F4.5 to F8, shutter speed 1/100 to 1/250 second). For inter-survey comparisons, models were geo-referenced using 20 to 30 ground control points (numbered black markers with a white target) placed around and within the feature, with their co-ordinates measured by survey-grade differential GNSS (Trimble R4). Volumetric estimates of soil loss were quantified using digital surface models (DSMs) derived from the repeat survey data and subtracted from a

    EarthCube is a new research initiative of the U.S. National Science Foundation, with the mission to develop community-guided cyberinfrastructure integrating data, models and other resources across geoscience disciplines. Analysis and modeling of physical processes that are not confined to disciplinary or jurisdictional boundaries, requires that data and models can be re-used outside the original context in which they are collected or developed. Infrastructure readiness for cross-domain interoperability encompasses the capabilities that need to be in place to enable such information re-use and ensure that it is both scientifically sound and technically feasible. In an ideal cross-domain information integration scenario, resources can be discovered via federated catalogs and linked nomenclatures from neighboring domains, while standard data services can be used to transparently compile composite data products and to integrate information using commonality in key data characteristics related to shared models of spatial features, time measurements, and observations. The main premise of the cross-domain readiness assessment is that when accessing domain resources from another domain, a user expects to be able to discover these resources, interpret them, retrieve the information, and integrate it with other data. Documentation of the resource must be sufficient for a user in a different context to determine fitness for use, and establish trust in scientific soundness. As part of an EarthCube roadmap focused on cross-domain interoperability, we explored a number of approaches to cyberinfrastructure readiness assessment, addressing both readiness of existing resources, and readiness of processes that enable cross-domain communication and information exchange across disciplinary boundaries. Our initial assessment considers basic infrastructure components required to enable cross-domain interoperability in the geosciences. These components, and the evaluation metrics

    Full Text Available Aim of the study is to assess how students in 6th, 7th and 8th grades of primary education see the project works made in science education and their implementation processes. The study was fulfilled upon the descriptive survey model to collect data. Participants of the research were 100 students who had project implementation experiences in science education, and they were from 24 primary schools in 7 districts randomly chosen in the city of Istanbul in Turkey. Data of the study were collected by using a semi-constructed interview form offered to students during the 2005-2006 teaching year. In the research, following items were examined: The extent to which students are inspired from the previously made projects during their own project selection process, the level of scientific document survey and the effects of contemporary events, science and technology class topics and students’ interest areas. It was seen that internet is the mostly used source to obtain information. For students, one of the most problematic issues faced during the project implementation is the time limits set out by teacher. It was found that the most obvious benefit obtained by students from the project works is their increasing interest towards science and technology class. The most significant change seen by students regarding project preparation is their increasing grades in exams during and following the project works.

    Abstract Background  An assessment of the process and outcomes of a health promotion programme is necessary for the continuous improvement of a programme. Objective  To explore the participants’ perceptions of the quality and effectiveness of the ‘Love Your Heart Programme’. Design  A qualitative study using semi‐structured interviews with a purposive sample of participants of the ‘Love Your Heart’ programme. Interviews were based on an interview guide that grouped questions into four main subgroups: structure, process, immediate outcomes and impact. The interviews were audio‐recorded, transcribed verbatim and analysed using the principles of grounded theory. Results  A total of 17 interviews were conducted. The participants were satisfied with the structural aspects of the programme. Different opinions arose regarding the ideal frequency and duration of the programme. The content of the seminars was thought to be too general. There was also a lack of interest in the ‘Road to a Healthy Heart’ booklet. All of the respondents had positive opinions about the communication skills and attitude of the health educator. The potential advantages and disadvantages of participating in the programme were discussed. Finally, the respondents expressed their satisfaction with the programme and the impact it had on them. Discussion and conclusions  In general, the participants who were interviewed held the programme, and the health educator conducted the programme in high regard. The suggestions that were received can be used to further improve the acceptability and feasibility of the programme. PMID:22050457

    Most users of complementary and alternative medicine (CAM) combine it with conventional medicine. Recent risk assessment studies have shown risks of negative interactions between CAM and conventional medicine, particularly when combining herbal medicine and conventional drug therapies (CDT). Little is known about the way users consider such risks. The present paper aims to gain knowledge about this issue by exploring views on risks of negative interactions when combining herbal medicine and CDT among people with multiple sclerosis (MS). This paper draws on a qualitative follow-up study on a survey among members of the Danish MS Society. Semi-structured, in-depth qualitative interviews were conducted with a strategic selection from the survey respondents. The study was inspired by a phenomenological approach and emerging themes were extracted from the data through meaning condensation. Four themes characterized the informants' views on risks of negative interactions when combining herbal medicine and CDT: 1) 'naturalness' in herbal medicine; 2) 'bodily sensations' as guidelines; 3) trust in the CAM practitioner; 4) lack of dialogue with medical doctor. Generally, the combination of herbal medicine and CDT was considered by the informants to be safe. In particular, they emphasized the 'non-chemical' nature of herbal medicine and of their own bodily sensations as warrants of safety. A trustful relation to the CAM practitioner furthermore made some of them feel safe in their use of herbal medicine and CDT in combination. The informants' use of bodily sensations as a non-discursive risk assessment may be a relevant element in understanding these issues.

    Previous studies using Olson's Circumplex Model and FACES IV, the self-report assessing family functioning, did not clarify the role of rigidity, a dimension of this model. Rigidity emerged as ambiguous: it was considered either as a functional or as a dysfunctional dimension. Building upon the results of previous studies, we provided a contribution intended to disambiguate the role of rigidity considering adolescents' perceptions and using a non-a priori classification analysis. 320 Italian adolescents (13-21 years) participated in this study and responded to a questionnaire containing scales of the study variables. A latent class analysis was performed to identify the association of rigidity with the other dimensions of Olson's model and with indicators of adaptive family functioning in adolescence: parental monitoring and family satisfaction. We found six clusters corresponding to family typologies and having different levels of functioning. Rigidity emerged as adaptive in the typologies named rigidly balanced and flexibly oscillating; it was associated with positive dimensions of family functioning, i.e. flexibility, cohesion, parental monitoring, and high levels of family satisfaction. Differently, when rigidity was associated with disengagement, low cohesion and flexibility, and lack of parental supervision, emerged as maladaptive. This was the case of two typologies: the rigidly disengaged and the chaotically disengaged. Adolescents of these families reported the lowest levels of satisfaction. In the two last typologies, the flexibly chaotic and the cohesively disorganized, rigidity indicated a mid-range functionality as these families were characterized by emotional connectedness but lack of containment. Clinical implications are discussed.

    Pico, Rene Antonio, II

    The purpose of this study was to investigate how teachers perceived and used performance assessment in the science classroom. Ms. Sanchez, Mrs. Irizarry, and Mrs. Bonnin, seventh grade teachers, participated in the study. Five research questions regarding the use of performance assessment were generated from these areas of inquiry: (a) teachers' views, (b) teachers' concerns, (c) teachers' level of use, (d) teachers' perceived facilitators, and (e) teachers' perceived barriers. Qualitative research methodologies were employed to collect and analyze the data. These included the use of informal interviews, a demographic survey, the Stage of Concern Questionnaire (Hall, George and Rutherford, 1979), the Level of Use Interview protocol (Loucks et al., 1975) and the study of artifacts. Performance assessment was defined by the three teachers as a dynamic process requiring the use of manipulatives in which students are involved as working participants in their own learning. Mrs. Irizarry and Mrs. Bonnin, described performance assessment with a broader range of possible executions, implying the use of tasks that allowed teachers to observe student behavior ranging from simple written responses to work collected over time. Ms. Sanchez defined assessment mainly on the basis of the use of equipment, instruments and materials in science. Ms. Sanchez reflected low intensity in the Levels of Concerns (Hall, George and Rutherford, 1979), suggesting that she felt at ease when working with performance assessment. Mrs. Irizarry and Mrs. Bonnin reflected definite commitment with the innovation. A major similarity was found in the areas of Refocusing (SoC 6), and Collaboration (SoC 5) denoting an interest in exploring and trying new alternatives. Ms. Sanchez and Mrs. Bonnin demonstrated characteristics of a well established routine or pattern in the Level of Use (Loucks et al., 1975) of performance assessment, while Mrs. Irizarry explored alternatives further and established a

    With the rise in obesity in America, the search for potential causes for this epidemic has begun to include a focus on environmental factors. Television (TV) viewing is one such factor, partially due to its potential as a stimulus for eating. The current study investigated the relationship between food intake and self-reported TV viewing in an effort to identify the impact of TV viewing on specific eating behaviors. Seventy-four overweight women seeking obesity treatment completed questionnaires assessing dietary habits and TV viewing behaviors. Results suggest that snacking, but not necessarily eating meals, while watching TV is associated with increased overall caloric intake and calories from fat. Therefore, interventions targeting stimulus control techniques to reduce snacking behavior may have an impact on overall caloric intake.

    Despite the focus during the last decade on introducing interventions such as senior doctor initial assessment or senior doctor triage (SDT) to reduce emergency department (ED) crowding, there has been little attempt to identify the views of emergency healthcare professionals on such interventions. The aim of this study was to gain an understanding of SDT from the perspective of emergency hospital staff. A secondary aim of this study was to develop a definition of SDT based on the interview findings and the available literature on this process. Qualitative semi-structured telephone interviews were conducted with participants of different backgrounds including senior doctors, nurses, paramedics and ED managers. Textual data were analysed using a template analysis approach. 27 participants from 13 EDs across England were interviewed. SDT was viewed as a safety mechanism and a measure to control patient flow. The most prominent positive aspect was the ability to initiate early investigations and treatment. Various shortcomings of SDT were described such as the lack of standardisation of the process and its cost implications. Participants identified a number of barriers to this process including insufficient resources and exit block, and called for solutions focused on these issues. A proposed definition of an 'ideal' SDT was developed where it is described as a systematic brief assessment of patients arriving at the ED by a senior doctor-led team, which takes place in a dedicated unit. The aim of this assessment is to facilitate early investigation and management of patients, early patient disposition and guide junior staff to deliver safe and high-quality clinical care. This is the first national study to explore the opinions of various emergency and managerial staff on the SDT model. It revealed variable interpretations of this model and what it can and cannot offer. This has led to a standard definition of the SDT process, which can be useful for clinicians and

    The "zograscope" is a "visual aid" (commonly known as "optical machine" in the 18th century) invented in the mid-18th century, and in general use until the early 20th century. It was intended to view single pictures (thus not stereographic pairs) with both eyes. The optics approximately eliminates the physiological cues (binocular disparity, vergence, accommodation, movement parallax, and image blur) that might indicate the flatness of the picture surface. The spatial structure of pictorial space is due to the remaining pictorial cues. As a consequence, many (or perhaps most) observers are aware of a heightened "plasticity" of the pictorial content for zograscopic as compared with natural viewing. We discuss the optics of the zograscope in some detail. Such an analysis is not available in the literature, whereas common "explanations" of the apparatus are evidently nonsensical. We constructed a zograscope, using modern parts, and present psychophysical data on its performance.

    To assess the influence of anatomic location on the relationship between computed tomography (CT) number and X-ray attenuation in limited and medium field-of-view (FOV) scans. Tubes containing solutions with different concentrations of K2HPO4 were placed in the tooth sockets of a human head phantom. Cone-beam computed tomography (CBCT) scans were acquired, and CT numbers of the K{sub 2}HPO{sub 4} solutions were measured. The relationship between CT number and K{sub 2}HPO{sub 4} concentration was examined by linear regression analyses. Then, the variation in CT number according to anatomic location was examined. The relationship between K{sub 2}HPO{sub 4} concentration and CT number was strongly linear. The slopes of the linear regressions for the limited FOVs were almost 2-fold lower than those for the medium FOVs. The absolute CT number differed between imaging protocols and anatomic locations. There is a strong linear relationship between X-ray attenuation and CT number. The specific imaging protocol and anatomic location of the object strongly influence this relationship.

    In June 2012, an Expression of Interest for a long-baseline experiment (LBNO, CERN-SPSC-EOI-007) has been submitted to the CERN SPSC and is presently under review. LBNO considers three types of neutrino detector technologies: a double-phase liquid argon (LAr) TPC and a magnetised iron detector as far detectors. For the near detector, a high-pressure gas TPC embedded in a calorimeter and a magnet is the baseline design. A mandatory milestone in view of any future long baseline experiment is a concrete prototyping effort towards the envisioned large-scale detectors, and an accompanying campaign of measurements aimed at assessing the systematic errors that will be affecting their intended physics programme. Following an encouraging feedback from 108th SPSC on the technology choices, we have defined as priority the construction and operation of a $6\\times 6\\times 6$m$^3$ (active volume) double-phase liquid argon (DLAr) demonstrator, and a parallel development of the technologies necessary for large magnetised MIN...

    Within the deinstitutionalization process of a large psychiatric hospital, the development of two cohorts of patients with chronic schizophrenia is compared over a two-year period: patients living in the hospital's nursing-home area (n = 50) vs. patients already released to two social therapeutic hostels (n = 51). Results of the cohort study were compared with assessments of nurses working in the nursing home (n = 55), focusing on their subjective views of the deinstitutionalization process and its impact on their working conditions. Patients are assessed through yearly home-visits in their place of residence. The instruments used measure several outcome parameters: psychopathology, social disabilities, subjective quality of life, and normative needs for care. Concurrent staff assessments were conducted using standardized survey instruments focusing on current working conditions and quality of teamwork. Nineteen nurses participated in qualitative interviews evaluating the deinstitutionalization process. For all measures, patients living in the nursing home show significantly worse outcomes. Furthermore, during the study period 34 % experienced a change in their living situation with which they were dissatisfied. Needs for care and the number of areas of "unmet" need increased significantly for this subgroup. Patients living in social therapeutic hostels demonstrate stable levels of psychopathological symptoms, social disabilities, and needs for care. Assessments indicating a deterioration in patients' subjective quality of life focus mainly on areas important for social contacts. Regarding "personal concerns" and "insecurity at work", ratings from nursing home staff were significantly worse than those of a reference group from several other health care institutions (n = 224). Staff showed a tendency to give higher ratings for their opportunities to participate in decisions, in contrast with the low ratings for chances to improve their knowledge in the workplace, a

    Full Text Available Structure from Motion with Multi-View Stereo photogrammetry (SfM-MVS is increasingly used in geoscience investigations, but has not been thoroughly tested in gullied savanna systems. The aim of this study was to test the accuracy of topographic models derived from aerial (via Unmanned Aerial Vehicle, ‘UAV’ and ground-based (via handheld digital camera, ‘ground’ SfM-MVS in modelling hillslope gully systems in a dry-tropical savanna, and to assess the strengths and limitations of the approach at a hillslope scale and an individual gully scale. UAV surveys covered three separate hillslope gully systems (with areas of 0.412–0.715 km2, while ground surveys assessed individual gullies within the broader systems (with areas of 350–750 m2. SfM-MVS topographic models, including Digital Surface Models (DSM and dense point clouds, were compared against RTK-GPS point data and a pre-existing airborne LiDAR Digital Elevation Model (DEM. Results indicate that UAV SfM-MVS can deliver topographic models with a resolution and accuracy suitable to define gully systems at a hillslope scale (e.g., approximately 0.1 m resolution with 0.4–1.2 m elevation error, while ground-based SfM-MVS is more capable of quantifying gully morphology (e.g., approximately 0.01 m resolution with 0.04–0.1 m elevation error. Despite difficulties in reconstructing vegetated surfaces, uncertainty as to optimal survey and processing designs, and high computational demands, this study has demonstrated great potential for SfM-MVS to be used as a cost-effective tool to aid in the mapping, modelling and management of hillslope gully systems at different scales, in savanna landscapes and elsewhere.

    In the UK, parental consent for the routine vaccination of 12-13 year olds schoolgirls against human papillomavirus (HPV) is recommended, although legally girls may be able to consent themselves. As part of a vaccine study conducted ahead of the National HPV Vaccine Programme we sought the views of school nurses on vaccinating girls who did not have parental consent. HPV vaccination was offered to all 12 year old girls attending schools in two Primary Care Trusts in Greater Manchester. At the end of the study semi-structured, tape-recorded interviews were conducted with school nurses who had delivered the vaccine (Cervarix). The interview template was based on concepts derived from the Theory of Planned Behaviour. Transcripts were analysed thematically in order to understand school nurses' intentions to implement vaccination based on an assessment of Gillick competency. School nurses knew how to assess the competency of under-16s but were still unwilling to vaccinate if parents had refused permission. If parents had not returned the consent form, school nurses were willing to contact parents, and also to negotiate with parents who had refused consent. They seemed unaware that parental involvement required the child's consent to avoid breaking confidentiality. Nurses' attitudes were influenced by the young appearance and age of the school year group rather than an individual's level of maturity. They were also confused about the legal guidelines governing consent. School nurses acknowledged the child's right to vaccination and strongly supported prevention of HPV infection but ultimately believed that it was the parents' right to give consent. Most were themselves parents and shared other parents' concerns about the vaccine's novelty and unknown long-term side effects. Rather than vaccinate without parental consent, school nurses would defer vaccination. Health providers have a duty of care to girls for whom no parental consent for HPV vaccination has been given

  2. A critical view of the mechanism(s) of toxicity of 2,3,7,8-tetrachlorodibenzo-p-dioxin. Implications for human safety assessment.

    1989-01-01

    2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) has been an important issue in occupational and environmental health for nearly two decades. During this period scientists have studied its possible impacts on exposed human populations. At the same time enormous efforts were made to elucidate the mechanism of TCDD action in various biological models. This paper provides a critical view of the advances made towards understanding the mechanism of TCDD action. Major topics discussed include the Ah-receptor hypothesis, TCDD as a thyroid hormone agonist, TCDD and vitamin A deficiency, TCDD's effect on receptor regulation, and its effect on intermediary metabolism including related hormonal responses. Although the exact mechanism of TCDD action is not yet known, more information is available on the toxicity of this compound than perhaps on that of any other substance. This wealth of information allows important conclusions regarding the assessment of acute, as well as of chronic, toxicities of TCDD for humans. There is no documented case of human death as a result of exposure to TCDD. It appears that humans are acutely less sensitive to TCDD than some animal species. The cause of TCDD-induced lethality in rats is a progressive lethal hypoglycemia due to inhibition of gluconeogenesis. Regulation of this metabolic pathway is quite different amongst species, although primates share great similarities. The assumption that the cause of TCDD-induced death in primates, in analogy to rats, is inhibition of gluconeogenesis would suggest that the acute toxicity of TCDD in humans would be in the range seen in rhesus monkeys (70-300 micrograms/kg). These values are about midway between the most (guinea pig) and least (hamster) sensitive species. TCDD is not a genotoxic agent and not an initiator, but promoter of tumor formation. There is considerable evidence that promotion of cancer, like any other chronic end point of toxicity, is a threshold-type biological process. Therefore, a linear

    What are the main contributing factors to road accidents? Factors such as inexperience, lack of skill, and risk-taking behaviors have been associated with the collisions of young drivers. In contrast, visual, cognitive, and mobility impairment have been associated with the collisions of older drivers. We investigated the main causes of road accidents by drawing on multiple sources: expert views of police officers, lay views of the driving public, and official road accident records. In Studies 1 and 2, police officers and the public were asked about the typical causes of road traffic collisions using hypothetical accident scenarios. In Study 3, we investigated whether the views of police officers and the public about accident causation influence their recall accuracy for factors reported to contribute to hypothetical road accidents. The results show that both expert views of police officers and lay views of the driving public closely approximated the typical factors associated with the collisions of young and older drivers, as determined from official accident records. The results also reveal potential underreporting of factors in existing accident records, identifying possible inadequacies in law enforcement practices for investigating driver distraction, drug and alcohol impairment, and uncorrected or defective eyesight. Our investigation also highlights a need for accident report forms to be continuously reviewed and updated to ensure that contributing factor lists reflect the full range of factors that contribute to road accidents. Finally, the views held by police officers and the public on accident causation influenced their memory recall of factors involved in hypothetical scenarios. These findings indicate that delay in completing accident report forms should be minimised, possibly by use of mobile reporting devices at the accident scene. Copyright © 2018 The Authors.

  7. Themes Underlying Australian General Practitioner Views towards Chiropractic and Osteopathy: An Assessment of Free Text Data from a Cross-Sectional Survey

    Directory of Open Access Journals (Sweden)

    2018-01-01

    Full Text Available The Australian chiropractic and osteopathic professions underwent a period of significant transformation between 1960 and 2000. This resulted in an improvement in the views held by the medical profession towards the two professions. However, a recent survey of Australian general practitioners (GPs reported that a number of GPs still hold negative views towards chiropractors and osteopaths. This paper examines these views from the perspective of critical realism and explores the generative mechanisms that can influence the willingness of health practitioners to collaborate over patient care. A qualitative analysis of open-ended responses to a survey of 630 Australian GPs was conducted. Unfavourable attitudes of GPs towards chiropractors and osteopaths included perceived lack of safety, efficacy, and inadequacy of training, despite chiropractic’s and osteopathy’s reliance on the same evidence base and similar training to those of other manual therapy professions such as physiotherapy. These attitudes may be underpinned by the professional biases against chiropractic and osteopathy that continue to marginalise the professions within the Australian healthcare system. Continued investment in the research base for chiropractic and osteopathic practice is required, along with raising the awareness of GPs about the education and skills of chiropractors and osteopaths.

  8. ENSI's view on NTB-10-01 'Evaluation of the geological documents for the provisional safety assessment in SGT Stage 2' - Sectoral Plan 'Deep Geological Disposal'

    International Nuclear Information System (INIS)

    2011-03-01

    As a preliminary action ahead of Stage 2 in the Sectoral Plan 'Deep Geological Disposal' ('Sachplan Geologische Tiefenlager': SGT) the bodies in charge of the management of the radioactive wastes have to determine, together with the Swiss Federal Nuclear Safety Inspectorate (ENSI), which complementary investigations are needed for the provisional safety assessment of the foreseen repositories. In particular, comparisons between the different sites must be possible. If some doubts remain, new investigations have to be conducted. In SGT Stage 1 the National Cooperative for the Disposal of Radioactive Waste (NAGRA) stated that a time period of 100'000 years shall be considered for the storage of low- and intermediate-level radioactive wastes (SMA) and of 1 million years for the storage of high-level wastes (HAA). In SGT Stage 2, considerations about possible modifications of the biosphere during the considered time periods for SMA as well as for HAA have to be included. In what regards the host rock, ENSI declares that the dataset describing the Opalinus clay is sufficient for the site-specific safety analyses. What regards the Wellenberg site for a SMA repository, ENSI has earlier analysed the license request of the NAGRA. For the Mergel formations of the Helveticum, NAGRA conducted a complete safety analysis. ENSI considers the knowledge acquired for these rock types as sufficient for the technical safety comparisons in SGT Stage 2. The knowledge of the rock 'Brauner Dogger' is correct but some more information about the lithostratigraphy and the biostratigraphy is requested. The understanding of the effect of the rock density reduction on the hydraulic conductibility of Opalinus clay and Mergel formations is accurate enough for the comparisons in SGT Stage 2. For the 'Brauner Dogger', comparable data are missing, but the proposed thickness of 300 m of the host rock offers a sufficient protection against density reduction effects. Concerning the behaviour of the

    Stereoscopic vision is a critical part of the human visual system, conveying more information than two-dimensional, monoscopic observation alone. This study aimed to quantify the contribution of stereoscopy in assessment of radiographic data, using widely available three-dimensional (3D)-capable display monitors by assessing whether stereoscopic viewing improved the characterisation of cerebral aneurysms. Nine radiology registrars were shown 40 different volume-rendered (VR) models of cerebral computed tomography angiograms (CTAs), each in both monoscopic and stereoscopic format and then asked to record aneurysm characteristics on short multiple-choice answer sheets. The monitor used was a current model commercially available 3D television. Responses were marked against a gold standard of assessments made by a consultant radiologist, using the original CT planar images on a diagnostic radiology computer workstation. The participants' results were fairly homogenous, with most showing no difference in diagnosis using stereoscopic VR models. One participant performed better on the monoscopic VR models. On average, monoscopic VRs achieved a slightly better diagnosis by 2.0%. Stereoscopy has a long history, but it has only recently become technically feasible for stored cross-sectional data to be adequately reformatted and displayed in this format. Scant literature exists to quantify the technology's possible contribution to medical imaging - this study attempts to build on this limited knowledge base and promote discussion within the field. Stereoscopic viewing of images should be further investigated and may well eventually find a permanent place in procedural and diagnostic medical imaging.

  10. Design and development of a LabVIEW-based LED-induced fluorescence spectroscopy system with applications in non-destructive quality assessment of agricultural products

    2016-01-01

    Over the past several years, the demand for high quality agricultural products has been remarkably increased. Thus, it is important to use non-destructive methods for product quality monitoring. LED-induced fluorescence spectroscopy has proved its potential for nondestructive detection of some defects in agricultural products, such as tissue browning and bruising. Due to such defects, changes in the polyphenol and chlorophyll contents occur which can be considered as the visible marks of decreasing fruit quality. In the present work, a fluorescence spectrometer (spectrofluorometer) controlled by LabVIEW software was designed and developed. In this spectrometer, a consumer-grade webcam was used as an imaging sensor. The spectrometer was able to measure the fluorescence spectra directly from the fruit and vegetable surface in the desired regions. To do so, the spectrometer was equipped with a suitable fiber-optic probe. The hardware solution was based on data acquisition working on the USB platform and controlled by the application running on the PC. In this system, light emitting diodes with different wavelengths were used as the excitation sources for inducing fluorescence spectra of some famous fruits and vegetables. (paper)

  15. Fate of organic microcontaminants in wastewater treatment and river systems: An uncertainty assessment in view of sampling strategy, and compound consumption rate and degradability.

    2017-11-15

    The growing awareness of the relevance of organic microcontaminants on the environment has led to a growing number of studies on attenuation of these compounds in wastewater treatment plants (WWTP) and rivers. However, the effects of the sampling strategies (frequency and duration of composite samples) on the attenuation estimates are largely unknown. Our goal was to assess how frequency and duration of composite samples influence uncertainty of the attenuation estimates in WWTPs and rivers. Furthermore, we also assessed how compound consumption rate and degradability influence uncertainty. The assessment was conducted through simulating the integrated wastewater system of Puigcerdà (NE Iberian Peninsula) using a sewer pattern generator and a coupled model of WWTP and river. Results showed that the sampling strategy is especially critical at the influent of WWTP, particularly when the number of toilet flushes containing the compound of interest is small (≤100 toilet flushes with compound day -1 ), and less critical at the effluent of the WWTP and in the river due to the mixing effects of the WWTP. For example, at the WWTP, when evaluating a compound that is present in 50 pulses·d -1 using a sampling frequency of 15-min to collect a 24-h composite sample, the attenuation uncertainty can range from 94% (0% degradability) to 9% (90% degradability). The estimation of attenuation in rivers is less critical than in WWTPs, as the attenuation uncertainty was lower than 10% for all evaluated scenarios. Interestingly, the errors in the estimates of attenuation are usually lower than those of loads for most sampling strategies and compound characteristics (e.g. consumption and degradability), although the opposite occurs for compounds with low consumption and inappropriate sampling strategies at the WWTP. Hence, when designing a sampling campaign, one should consider the influence of compounds' consumption and degradability as well as the desired level of accuracy in

This study examines point clouds produced using MVS techniques applied to UAV and terrestrial photography. A multi-rotor micro UAV acquired aerial imagery from a altitude of approximately 30–40 m. The point clouds produced are extremely dense (<1–3 cm point spacing and provide a detailed record of the surface in the study area, a 70 m section of sheltered coastline in southeast Tasmania. Areas with little surface texture were not well captured, similarly, areas with complex geometry such as grass tussocks and woody scrub were not well mapped. The process fails to penetrate vegetation, but extracts very detailed terrain in unvegetated areas. Initially the point clouds are in an arbitrary coordinate system and need to be georeferenced. A Helmert transformation is applied based on matching ground control points (GCPs identified in the point clouds to GCPs surveying with differential GPS. These point clouds can be used, alongside laser scanning and more traditional techniques, to provide very detailed and precise representations of a range of landscapes at key moments. There are many potential applications for the UAV-MVS technique, including coastal erosion and accretion monitoring, mine surveying and other environmental monitoring applications. For the generated point clouds to be used in spatial applications they need to be converted to surface models that reduce dataset size without loosing too much detail. Triangulated meshes are one option, another is Poisson Surface Reconstruction. This latter option makes use of point normal

    We present a seismogenic source model for site-specific probabilistic seismic hazard assessment at the sites of Swiss nuclear power plants. Our model is one of four developed in the framework of the PEGASOS project; it contains a logic tree with nine levels of decision-making. The two primary sources of input used in the areal zonation developed by us are the historical and instrumental seismicity record and large-scale geological/rheological units. From this, we develop a zonation of six macro zones, refined in a series of seven decision steps up to a maximum of 13 zones. Within zones, activity rates are either assumed homogeneous or smoothed using a Gaussian kernel with width of 5 or 15 km. To estimate recurrence rate, we assume a double truncated Gutenberg-Richter law, and consider five models of recurrence parameters with different degrees of freedom. Models are weighted in the logic tree using a weighted Akaike score. The maximum magnitude is estimated following the EPRI approach. We perform extensive sensitivity analyses in rate and hazard space in order to assess the role of de-clustering, the completeness model, quarry contamination, border properties, stationarity, regional b-value and magnitude-dependent hypocentral depth.

    Pedersen, Dennis; Pedersen, Torben Bach

    2004-01-01

    The increasing availability of XML-based data sources, e.g., for publishing data on the WWW, means that more and more applications (data consumers) rely on accessing and using XML data. Typically, the access is achieved by defining views over the XML data, and accessing data through these views....... However, the XML data sources are often independent of the data consumers and may change their schemas without notification, invalidating the XML views defined by the data consumers. This requires the view definitions to be updated to reflect the new structure of the data sources, a process termed view...... synchronization. XPath is the most commonly used language for retrieving parts of XML documents, and is thus an important cornerstone for XML view definitions. This paper presents techniques for discovering schema changes in XML data sources and synchronizing XPath-based views to reflect these schema changes...

    Full Text Available Introduction. Nowadays, the use of information and communication technologies (ICT has become an integral part both of every individual’s life and of the society in general. It is no longer possible to deny the impact of virtual environment on socialisation and development of the identity of young people. In this regard, the investigation of young people’s view on virtual social networks, and the possibility of students’ own competitiveness realization through various web services. The aim of the research presented in the article is to study the factors of students’ assessment of virtual social networks as a tool of personal fulfillment. Methodology and research methods. Content analysis and synthesis of scientific publications studies were carried out at a theoretical stage of the research; secondary sampling analysis of sociologic data material sources was conducted. The empirical research stage involved the instrument of questionnaire surveys, statistical data processing and interpretation of the results. Results and scientific novelty. The social survey conducted in 2017 with the participation of 1087 high school students and 1196 college students of the Tyumen Region shown that the more competitive students consider themselves, the more competitive they perceive the people having great popularity on the Internet. At that, compared to girls, young people are more inclined to consider the people having great popularity on the Internet competitive. It is determined that having a popular virtual media account for the young person is less worthwhile than for female respondents. The author explains this fact: male representatives regard it as “social capital” which can contribute to growth of their competitiveness in society as well as to achieve some profit. The author concludes that youth views on competitiveness are not directly related to the activity in virtual social networks. Frequent use by respondents of the Internet and

  3. A Dynamical View of High School Attendance: An Assessment of Short-term and Long-term Dependencies in Five Urban Schools.

    While school attendance is a critical mediator to academic achievement, its time dependent characteristics are rarely investigated. To remedy situation, this paper reports on the analysis of daily attendance rates in five urban high schools over a seven-year period. Traditional time series analyses were conducted to estimate short-range and cyclical dependencies in the data. An Autoregressive Fractional Integrated Moving Average (ARFIMA) approach was used to address long-range correlational patterns, and detect signs of self-organized criticality. The analysis reveals a strong cyclical pattern (weekly) in all five schools, and evidence for self-organized criticality in one of the five. These findings illustrate the insufficiency of traditional statistical summary measures to characterize the distribution of daily attendance, and they suggest that daily attendance is not necessarily the stable and predictable feature of school effectiveness it is conventionally assumed to be. While educational practitioners can probably attest to the many of the irregularities in attendance patterns as well as some of their sources, a systematic description of these temporal aspects needs to be included in our assessment of daily attendance behavior to inform policy decisions, if only to better align formal research in this area with existing local knowledge about those patterns.

    During the last few years there has been a growing interest in research focused on the metabolism of steroid hormones despite that the study of metabolic hormone pathways is still a difficult and demanding task because of low steroid concentrations and a complexity of the analysed matrices. Thus, there has been an increasing interest in the development of new, more selective and sensitive methods for monitoring these compounds in biological samples. A lot of bibliographic databases for world research literature were structurally searched using selected review question and inclusion/exclusion criteria. Next, the reports of the highest quality were selected using standard tools (181) and they were described to evaluate the advantages and limitations of different approaches in the measurements of the steroids and their metabolites. The overview of the analytical challenges, development of methods used in the assessment of the metabolic pathways of steroid hormones, and the priorities for future research with a special consideration for liquid chromatography (LC) and capillary electrophoresis (CE) techniques have been presented. Moreover, many LC and CE applications in pharmacological and psychological studies as well as endocrinology and sports medicine, taking into account the recent progress in the area of the metabolic profiling of steroids, have been critically discussed. The latest reports show that LC systems coupled with mass spectrometry have the predominant position in the research of steroid profiles. Moreover, CE techniques are going to gain a prominent position in the diagnosis of hormone levels in the near future.

    The objective was to determine the relevance and applicability of psychological questionnaires to patients seeking help for tinnitus and/or hyperacusis. This was a questionnaire-based survey. The following questionnaires were administered: Generalised Anxiety Disorder (GAD-7), Short Health Anxiety Inventory (SHAI), Mini-Social Phobia Inventory (Mini-SPIN), Obsessive Compulsive Inventory-Revised (OCI-R), Panic Disorder Severity Scale-Self Report (PDSS-SR), Patient Health Questionnaire (PHQ-9) and Penn State Worry Questionnaire-Abbreviated version (PSWQ-A). In addition, a patient feedback questionnaire was completed asking about the extent to which each questionnaire was relevant to them and how strongly they would recommend its use in the assessment of patients with tinnitus and hyperacusis. A total of 150/402 consecutive patients seen in a one-year period completed the questionnaires. 65% of patients had abnormal scores for one or more of the questionnaires. All questionnaires except the PDSS-SR were rated as relevant and recommended for use. The GAD-7, SHAI, Mini-SPIN, OCI-R, PSWQ-A and PHQ-9 are recommended for evaluation of psychological problems for patients seeking help for tinnitus and/or hyperacusis. Abnormal results on these questionnaires may indicate the need for referral for possible treatment of psychological problems.

    intends to briefly address the transformations arising from the technological and informational revolution which, in addition to being directly related to students’ lives, also compromise the socialization of knowledge, which, consequently, learning by the student. From this context and from the statistical data of the Census of Higher Education and its results, a historical analysis is made first, with a view to understanding the learning challenges involved, mainly, by the contemporary transformations that are related both to the faculty as the student. In this way, it is concluded that school culture, constructed by compartmentalizing knowledge, needs to restore natural abilities to contextualize knowledge, to integrate them into their sets (Morin, 2003. In this sense, it is possible to consider that the learning process becomes more effective, and may lead to a change from a deterministic and formal vision to a freer and more creative perception. Contextualization will become synonymous with the integration of knowledge for the conduct of academic day-to-day.Keywords: University education. Learning.

    Full Text Available Habitat mapping can be accomplished using many techniques and types of data. There are pros and cons for each technique and dataset, therefore, the goal of this project was to investigate the capabilities of new satellite sensor technology and to assess map accuracy for a variety of image classification techniques based on hundreds of field-work sites. The study area was Masonboro Island, an undeveloped area in coastal North Carolina, USA. Using the best map results, a habitat change assessment was conducted between 2002 and 2010. WorldView-2, QuickBird, and IKONOS satellite sensors were tested using unsupervised and supervised methods using a variety of spectral band combinations. Light Detection and Ranging (LiDAR elevation and texture data pan-sharpening, and spatial filtering were also tested. In total, 200 maps were generated and results indicated that WorldView-2 was consistently more accurate than QuickBird and IKONOS. Supervised maps were more accurate than unsupervised in 80% of the maps. Pan-sharpening the images did not consistently improve map accuracy but using a majority filter generally increased map accuracy. During the relatively short eight-year period, 20% of the coastal study area changed with intertidal marsh experiencing the most change. Smaller habitat classes changed substantially as well. For example, 84% of upland scrub-shrub experienced change. These results document the dynamic nature of coastal habitats, validate the use of the relatively new Worldview-2 sensor, and may be used to guide future coastal habitat mapping.

  8. Runoff experiment and adapted SfM photogrammetry to assess rill erosion in Mediterranean agricultural fields from a holistic point of view

    2017-04-01

    In Mediterranean agricultural fields, more research is needed to quantify soil loss and to assess runoff generation caused by unsuitable land management strategies (García-Díaz et al., 2017; Keesstra et al., 2016). Nowadays, farmers are increasing the generation of rills and, consequently, enhancing several sub-processes related to soil erosion by water such as headcut retreats, piping or cracks joint to mass movements (Marzolff and Poesen, 2009; Poesen et al., 2003; Rodrigo Comino et al., 2015). This complex problem under different spatiotemporal scales hinders a reliable forecasting of its final consequences (Prasuhn, 2011; Salome et al., 2014). Several researchers pay more attention to point observations, but no to general and connected overviews of processes related to forms and the quantitative functioning of all elements. Therefore, the main goal of this study is to characterize and quantify the rill erosion generated by these degradation processes. To achieve this goal, two runoff experiments were carried out with two repetitions (dry and wet conditions) under extreme conditions (Wirtz et al., 2013, 2012, 2010): a motor driven pump discharged a water inflow up to ˜4.2 l s-1 maintained during between 4 and 6 minutes (≈1000 litres). Additionally, a 3D-captation of the rill by an adapted SfM photogrammetry was performed to assess: i) clear visible zonation of geomorphological (structural) connectivity features; ii) runoff and sediment productions close to the catchment outlet under actual conditions; iii) topsoil-subsoil interaction and crusting crucial for runoff generation; and, iv) the area with evidence of (former) high erosion intensity now stable, but with remnant.

    Full Text Available BACKGROUND: We aimed to assess, for the first time, the nature of the indoor air contamination of hospitals. METHODS AND FINDINGS: More than 40 volatile organic compounds (VOCs including aliphatic, aromatic and halogenated hydrocarbons, aldehydes, alcohols, ketones, ethers and terpenes were measured in a teaching hospital in France, from sampling in six sampling sites--reception hall, patient room, nursing care, post-anesthesia care unit, parasitology-mycology laboratory and flexible endoscope disinfection unit--in the morning and in the afternoon, during three consecutive days. Our results showed that the main compounds found in indoor air were alcohols (arithmetic means ± SD: 928±958 µg/m³ and 47.9±52.2 µg/m³ for ethanol and isopropanol, respectively, ethers (75.6±157 µg/m³ for ether and ketones (22.6±20.6 µg/m³ for acetone. Concentrations levels of aromatic and halogenated hydrocarbons, ketones, aldehydes and limonene were widely variable between sampling sites, due to building age and type of products used according to health activities conducted in each site. A high temporal variability was observed in concentrations of alcohols, probably due to the intensive use of alcohol-based hand rubs in all sites. Qualitative analysis of air samples led to the identification of other compounds, including siloxanes (hexamethyldisiloxane, octamethyltrisiloxane, decamethylcyclopentasiloxane, anesthetic gases (sevoflurane, desflurane, aliphatic hydrocarbons (butane, esters (ethylacetate, terpenes (camphor, α-bisabolol, aldehydes (benzaldehyde and organic acids (benzoic acid depending on sites. CONCLUSION: For all compounds, concentrations measured were lower than concentrations known to be harmful in humans. However, results showed that indoor air of sampling locations contains a complex mixture of VOCs. Further multicenter studies are required to compare these results.

    To assess the value of the lateral view in the diagnosis of pleural plaques, 2018 chest roentgenograms from the general population were scrutinized for such plaques. The lateral and posterior-anterior (PA) views were read separately and without knowledge of the occupational history or other clinical data. Of the males, 4.8% had pleural plaques in the PA view and 2% had dorsal pleural plaques in the lateral view. A total of 54% of the positive cases in the PA view also showed typical plaques in the PA view. Thus, there remained a number of cases which were diagnosed only in the lateral view; in all, these constituted 18.8%

    standard; both the composts can be used as fertilizers or soil amendments. In order to eliminate glass impurity, remediation approaches such as fine milling and pelleting is needed to disguise the residual glasses and render it as relatively harmless. A feasible approach to eliminate these problems is probably physical fractionation of the studied composts. It allows us to assess the distribution of nutrients and contaminants values in the different physical fractions of the composts, which is useful to detect and to eliminate of the particle sizes which are the responsible for these impurities. Conclusion: The assessment of MSW-based compost for use in agricultural soil as fertilizer or conditioner is a sustainable recycling practice owing to its nutrient content and its positive effects on soil physico-chemical properties. Thus, we evaluated the fertilizing potential of two MSW composts produced in Sanandaj city for agricultural purposes. Altogether, the results of the study showed that excessive amount of glass impurity bigger than 2 mm and salinity were the major problems in the use of the composts for agricultural purpose. As a result, the quality of the surveyed composts was not suitable for agricultural purposes without appropriate remediation of these restrictions.

    2014-01-01

    The useful field of view test was developed to reflect the visual difficulties that older adults experience with everyday tasks. Importantly, the useful field of view test (UFOV) is one of the most extensively researched and promising predictor tests for a range of driving outcomes measures, including driving ability and crash risk as well as other everyday tasks. Currently available commercial versions of the test can be administered using personal computers; these measure the speed of visual processing for rapid detection and localization of targets under conditions of divided visual attention and in the presence and absence of visual clutter. The test is believed to assess higher-order cognitive abilities, but performance also relies on visual sensory function because in order for targets to be attended to, they must be visible. The format of the UFOV has been modified over the years; the original version estimated the spatial extent of useful field of view, while the latest version measures visual processing speed. While deficits in the useful field of view are associated with functional impairments in everyday activities in older adults, there is also emerging evidence from several research groups that improvements in visual processing speed can be achieved through training. These improvements have been shown to reduce crash risk, and can have a positive impact on health and functional well-being, with the potential to increase the mobility and hence the independence of older adults. © 2014 S.

  19. Hierarchical Linked Views

    Erbacher, Robert; Frincke, Deb

    2007-07-02

    Coordinated views have proven critical to the development of effective visualization environments. This results from the fact that a single view or representation of the data cannot show all of the intricacies of a given data set. Additionally, users will often need to correlate more data parameters than can effectively be integrated into a single visual display. Typically, development of multiple-linked views results in an adhoc configuration of views and associated interactions. The hierarchical model we are proposing is geared towards more effective organization of such environments and the views they encompass. At the same time, this model can effectively integrate much of the prior work on interactive and visual frameworks. Additionally, we expand the concept of views to incorporate perceptual views. This is related to the fact that visual displays can have information encoded at various levels of focus. Thus, a global view of the display provides overall trends of the data while focusing in on individual elements provides detailed specifics. By integrating interaction and perception into a single model, we show how one impacts the other. Typically, interaction and perception are considered separately, however, when interaction is being considered at a fundamental level and allowed to direct/modify the visualization directly we must consider them simultaneously and how they impact one another.

    In the UK, patients frequently choose complementary (CAM) therapies, particularly for chronic painful musculoskeletal conditions. It is widely agreed that better integration of complementary and traditional healthcare is desirable. We piloted the Benefits and Risks of Treatment Questionnaire to compare the views of different healthcare practitioners about traditional and alternative approaches in one clinical scenario in order to assess barriers to effective integration. A cross-sectional survey of healthcare practitioners (primary care practitioners, physiotherapists, pharmacists, osteopaths, chiropractors and acupuncturists) in the UK. The views of all healthcare providers were compared using the exemplar of neck, shoulder and upper arm pain to explore the perceived risks and benefits of different types of therapeutic intervention using a mathematical cluster approach. 448/1254 (36%) useable replies were received representing all six professions. A mean of 14.9 years of experience was reported by participants. The cluster analyses revealed distinct clusters of opinion of benefit: primary care physicians, physiotherapists and pharmacists were significantly more likely to rate a cluster including: anti-inflammatory drugs, steroid injections, steroids, physiotherapy, paracetamol and antidepressants as beneficial for neck, shoulder and upper arm pain. In contrast, osteopaths and chiropractors, but not physiotherapists were significantly more likely to rate a cluster including chiropractic, osteopathy and physiotherapy as beneficial. The Beliefs about Risks and Benefits of Treatments Questionnaire can be applied using a postal approach and achieves similar response rates to other surveys amongst healthcare practitioners. Despite widespread agreement that increased integration of traditional and alternative approaches is desirable, the results of this study suggest that experienced practitioners show the strongest belief in the benefit of approaches closest to their

    Sheffield Profile for Assessment and Referral for Care (SPARC) was developed in response to concerns that palliative care may not be reaching all people who could benefit from it. Acceptability of the tool is an important step in developing its future use. To elicit the views of a wide variety of members of consumer and self-help support groups concerned with health care on the relevance, acceptability and the overall perception of using SPARC as an early holistic needs assessment tool in supportive and palliative care. This study was conducted in South Yorkshire and North Derbyshire (UK). Ninety-nine consumer and self-help groups were identified from information in the public domain. Thirty-eight groups participated. Packs containing study information and self-complete postal questionnaires were distributed to groups, and they were asked to circulate these to their members. Completed questionnaires were returned in pre-paid envelopes to the research team. 135 questionnaires and feedback forms were returned. The majority of respondents found SPARC easy to understand (93% (120/129; 95% Confidence Interval 87% to 96%) and complete (94% (125/133; 95% CI: 88% to 97%). A minority, 12.2% (16/131), of respondents found questions on SPARC 'too sensitive'. Overall, respondents considered SPARC an acceptable and relevant tool for clinical assessment of supportive and palliative-care needs. Whilst a small minority of people found SPARC difficult to understand (i.e. patients with cognitive impairments), most categories of service user found it relevant. Clinical studies are necessary to establish the clinical utility of SPARC. © 2013 John Wiley & Sons Ltd.

Y en la medida en que lo lograba, la biografía, como género invertido entre lo ficcional y lo factual, debió ser desterrada para que así la Historia, que debía escribirse con H mayúscula, alcanzara la ansiada respetabilidad científica. Dado su carácter inclasificable e impuro, por su cercanía a lo literario, a lo intuitivo, a lo emotivo o a cualquier tipo de subjetivismo, la biografía terminó por ser recluida al cuarto de las cosas viejas, allá atrás donde no hiciera pasar vergüenza a nadie, junto a las trompetas y los tambores de la historia de los grandes héroes.

  12. "My story is like a goat tied to a hook." Views from a marginalized tribal group in Kerala (India) on the consequences of falling ill: a participatory poverty and health assessment.

    Science.gov (United States)

    Mohindra, K S; Narayana, D; Haddad, Slim

    2010-06-01

    Indigenous populations tend to have the poorest health outcomes worldwide and they have limited opportunities to present their own perspectives of their situation and shape priorities in research and policy. This study aims to explain low healthcare utilisation rates and opportunities to cope with illness among a deprived indigenous group - based on their own experiences and views. A participatory poverty and health assessment (PPHA) was conducted among the Paniyas, a previously enslaved tribal population of South India in a Gram Panchayat in Kerala, India in 2008. Purposive sampling was used to select five Paniya colonies, involving 66 households. There were four key findings. First, Paniyas' perception that the quality of the public healthcare system is poor leads them to seek suboptimal care or deters them from using services. Second, there are significant costs of care unrelated to service use or purchase of medicines, such as travel costs, which the Paniyas lack the ability to pay. Third, illness can lead to loss of productive opportunities among those who fall ill and those who provide informal care. Fourth, the Paniyas lack a 'range' of coping strategies as they are wage labourers without diverse sources of income. They rely on a single strategy: borrowing from outside their community, often from landowners and employers, to whom they become indebted with their labour. Improving the capacity of tribal populations to present their own perspectives is likely to lead to more effective tribal development policies and consequently better health.

  13. Immersive viewing engine

    Schonlau, William J.

    2006-05-01

    An immersive viewing engine providing basic telepresence functionality for a variety of application types is presented. Augmented reality, teleoperation and virtual reality applications all benefit from the use of head mounted display devices that present imagery appropriate to the user's head orientation at full frame rates. Our primary application is the viewing of remote environments, as with a camera equipped teleoperated vehicle. The conventional approach where imagery from a narrow field camera onboard the vehicle is presented to the user on a small rectangular screen is contrasted with an immersive viewing system where a cylindrical or spherical format image is received from a panoramic camera on the vehicle, resampled in response to sensed user head orientation and presented via wide field eyewear display, approaching 180 degrees of horizontal field. Of primary interest is the user's enhanced ability to perceive and understand image content, even when image resolution parameters are poor, due to the innate visual integration and 3-D model generation capabilities of the human visual system. A mathematical model for tracking user head position and resampling the panoramic image to attain distortion free viewing of the region appropriate to the user's current head pose is presented and consideration is given to providing the user with stereo viewing generated from depth map information derived using stereo from motion algorithms.

  2. An investigation into why two-view mammography is better than one-view in breast cancer screening

    Hackshaw, A.K.; Wald, N.J.; Michell, M.J.; Field, S.; Wilson, A.R.M.

    2000-01-01

    AIM: To determine why two-view mammography in screening for breast cancer is more effective than using a single medio-lateral oblique view. MATERIALS AND METHODS: In the United Kingdom Coordinating Committee on Cancer Research randomized trial of one- vs two-view mammography in breast cancer screening the oblique view was assessed by one radiologist and two views (oblique and cranio-caudal) assessed by another. For the present study the mammographic films were retrieved from the screening centres and assessed by three consultant radiologists. Mammographic films were available from 110 women; 87 had their breast cancer detected by both one and two views and in 23 it was missed by one view but detected using two views. Outcome measures were breast size, location and size of the cancer, mammographic features, presence of microcalcification and overall radiological assessment. RESULTS: Although 23 cancers were missed in the original trial when one view was used, only two were not visible on the oblique view. Cancers missed using a single oblique view (and only detected if the cranio-caudal view was available with the oblique) tended to be smaller by about 4 mm (P = 0.05), centrally located in the breast (P = 0.16), not spiculated or round, (P ≤ 0.001) and lacked microcalcification (P = 0.15). Breast size and breast radiographic density were not significantly associated with breast cancer detection. CONCLUSIONS: The results provide the basis for the observation that two-view mammographic screening is more effective than one-view mammographic screening. Hackshaw, A. (2000).

    Full Text Available An audiovisual interface equipped with a projector, an inclina-tion sensor, and a distance sensor for zoom control has been developed that enables a user to selectively view and listen to specific performers in a video-taped group performance. Dubbed Concert Viewing Headphones, it has both image and sound processing functions. The image processing extracts the portion of the image indicated by the user and projects it free of distortion on the front and side walls. The sound processing creates imaginary microphones for those performers without one so that the user can hear the sound from any performer. Testing using images and sounds captured using a fisheye-lens camera and 37 lavalier microphones showed that sound locali-zation was fastest when an inverse square function was used for the sound mixing and that the zoom function was useful for locating the desired sound performance.

    This article reports the observations of correspondents for the Bulletin (two Russian journalists, one based in Moscow, the other in Kiev) who investigated the status of the Soviet Union's Black Sea Fleet and Ukraine's status as a non-nuclear-weapons state. After two years of wrangling and two earlier failed settlements, Russian President Boris Yeltsin met with Ukrainian President Leonid Kravchuk at Massandra in Crimea. On September 3, the leaders announced that Russia would buy out Ukraine's interest in the fleet and lease the port at Sevastopol. The Massandra summit was also supposed to settle Ukraine's status as a non-nuclear-weapons state. Described here are the Kiev-based correspondent's views on the Massandra summit (and its major topics), which was to have been called off by the Russian foreign ministry when Ukrainian Prime Minister Leonid Kuchma resigned

    Full Text Available The plastic effect is historically used to denote various forms of stereopsis. The vivid impression of depth often associated with binocular stereopsis can also be achieved in other ways, for example, using a synopter. Accounts of this go back over a hundred years. These ways of viewing all aim to diminish sensorial evidence that the picture is physically flat. Although various viewing modes have been proposed in the literature, their effects have never been compared. In the current study, we compared three viewing modes: monocular blur, synoptic viewing, and free viewing (using a placebo synopter. By designing a physical embodiment that was indistinguishable for the three experimental conditions, we kept observers naïve with respect to the differences between them; 197 observers participated in an experiment where the three viewing modes were compared by performing a rating task. Results indicate that synoptic viewing causes the largest plastic effect. Monocular blur scores lower than synoptic viewing but is still rated significantly higher than the baseline conditions. The results strengthen the idea that synoptic viewing is not due to a placebo effect. Furthermore, monocular blur has been verified for the first time as a way of experiencing the plastic effect, although the effect is smaller than synoptic viewing. We discuss the results with respect to the theoretical basis for the plastic effect. We show that current theories are not described with sufficient details to explain the differences we found.

    This paper is the result of five years of experience with the nuclear world in Switzerland (five Swiss nuclear plants) from the point of view of a journalist, who doesn't pretend to know everything; who is neither scientific nor a technical journalist, he is writing for the man in the street, and works for a daily paper i.e. has to work very fast and as close to the reality as possible. Understanding and mutual confidence between the nuclear industry and media is emphasised as essential. 'Nuclear' people are specialists and are warned about the fact that they are dealing with non-specialists, journalists and the public who would like to understand what are the processes that might affect them and do not have a dictionary of technical terminology at hand. It is pointed out that the nuclear industry should speak openly about problems and accept being criticised if they want to restore confidence with the media and with the public

    “La mirada vigente” is a homenage to Dan Beninson, who was one of the creators of radiation protection worldwide. He taught several generations of nuclear scientists in our country and abroad, playing a key role in the scientific-technological development of Argentina. He was also one of the key figures in the nuclear activity of our country; the creator of the institution that ensures its safety. Likewise, this book, is a testament about what this man meant for many people in Argentina (his country) and in the world (his yard); and simultaneously, a testament of the key moments in the history of a scientific discipline and the activity to which he dedicated his entire life. “La mirada vigente” is also a testimony of other individuals’ point of view. The eyes of others over the features of his person, and career, and his achievements. But above all, it provides a personal and almost intimate perspective, about specific episodes that describe his interesting life. “La mirada vigente” is the exploration of his versatile life, rich as only a few. And the reflection of a work legacy that still remain alive. [es

  1. Dutch radiodiagnostics viewed internationally

    1990-01-01

    Dutch radiodiagnostics viewed internationally. - A quantitative description of diagnostic radiology is given in terms of radiological density (the number of radiological examinations per 1000 inhibitants), consumptions of roentgen film and contrast media. The data concerning examinations were recorded by a yearly inquiry system addressing all Dutch radiologists. The consumption of film and contrast media were derived from the data banks of the industries. In comparing these data with the data for Western Europe, Japan and the United States it is remarkable that diagnostic radiology scores lowest in regard to density, film consumption and use of contrast media. Only in the use of 35 mm cinefilm (coronary angiography) is The Netherlands number 2 on the list preceded by the United States. As a consequence radiation exposure of the population caused by diagnostic radiology is low in The Netherlands. Although the technical condition of the equipment is good due to regular and preventive service the life-span of the radiological equipment is gradually increasing beyond the limits of the normal economic depreciation. Growing arrears are found in the application of new technology: ultrasound, computer tomography and magnetic resonance imaging. The substitution of high osmolar contrast media by low osmolar media is also laggin gbehind. (author). 10 refs.; 1 fig.; 4 tab

    The personal experiences at the Beijing Fourth World Conference on Women and the Nongovernmental Organization (NGO) Forum were described by a Chinese American veterinarian. The author became aware that women were primarily the persons living in poverty in the world. Business and government appeared more concerned with economic growth. As a consequence, developed countries with 20% of world population consume 80% of the world's resources. The privilege of money secures a position of power in the world, power to buy up the resources of the world. This process is unsustainable and inequitable. Women are viewed as key players in shifting the balance in favor of a higher quality of life. The NGO workshops on Women in Livestock Development (WILD) was run by women veterinarians, who worked at the local level with women in poor areas. WILD operates out of offices in Arkansas in the USA. WILD women work in Sichuan, China, among the Han and Tibetans in increasing family income through heifer and livestock production. Conference participants from WILD programs talked about their experiences with increased income and loans to other women. The World Women's Veterinary Association members, who attended the conference, visited a small animal clinic in Beijing run by the Agriculture Ministry, and Beijing Agricultural University and its Veterinary Teaching Hospital. Demonstrations were given of small animal acupuncture. The author found the conference to be a success and found that press reports misrepresented the energy generated by the meeting.

    The peak-to-valley (PTV) method was investigated experimentally comparing PTV ratios for three HPGe detectors, with complementary Monte Carlo simulations of scatter in air for larger source-detector distances. The measured PTV ratios for 137Cs in air were similar for three different detectors for incident angles between 0 and 90°. The study indicated that the PTV method can differentiate between surface and shallow depth sources if the detector field of view is limited to a radius of less than 3.5m.

  8. School violence: an insider view.

    Science.gov (United States)

    Johnson, Shelley A; Fisher, Kathleen

    2003-01-01

    To discover what teachers perceive to be contributing factors to violence in schools. Open-ended questions were asked of a convenience sample of teachers ( = 396) during an in-service education program on school violence. The teachers were in a semi-rural school district in a Mid-Atlantic state. Answers were analyzed using content analysis; all responses were reviewed and important themes were extracted. Identified themes were then placed into suitable categories and studied to determine relationships. Of the surveys analyzed ( = 239), 13 themes were identified. The three categories which then identified probable causes of school violence were (1) lack of knowledge, (2) lack of support, and (3) inadequate safety measures. Nurses can use the results of this study in multiple ways. One is to help parents understand their role in preventing school violence. Because violence in the home and violence in the media seem to foster violent acting-out behavior, nurses can teach parents about these correlations and seek solutions such as the elimination of family violence, and monitoring television viewing and video games. Nursing assessments of school-aged children and their families can include these elements. School nurses in particular can use these study results as an opportunity to develop interventions for students, teachers, and families that stress knowledge building about impulse control, anger management, appropriate parenting, and early intervention for at-risk children.

    Nasoduodenal tube (NDT) placement is typically performed at the bedside and two-view abdominal radiographs are usually used to confirm tube position. Anecdotally, in most instances the lateral view is unnecessary and utilizes more than twice the radiation than an anteroposterior (AP) view alone. We hypothesize that NDT location can be determined using only the AP view, with the NDT position determined on two views utilized as the gold standard. A search was performed for all two- or three-view abdominal radiographs from September 2012 to September 2013 with the phrase ''ND tube'' in the reason field of the requisition. These studies were independently reviewed by two radiologists and scored for anatomical tube position in three different scenarios: AP view alone, the lateral view alone, and both views together, with the latter serving as the gold standard. The anatomical scores were subsequently grouped to reflect clinically significant scenarios. Comparative analysis was performed with the original and clinically grouped scores. A total of 102 patients and 306 separate two-view exams were evaluated. Of the 102 patients, 55 had at least two separate exams. Across raters, concordances of AP and lateral scores relative to the gold standard assessment were 88% and 73% for anatomical scores, and 91.5% and 86.4% for clinically grouped data. Trend differences for fewer errors were found with the AP compared to the lateral view. There were statistically significant group differences with a greater number of false-negative errors in the lateral data set. No clear differences were found when comparing AP and lateral ratings for false-positive errors. Upon review of the common errors, we determined a few imaging findings on AP radiographs that can help assess the need for an additional lateral view. A single AP view is sufficient to determine the NDT position in most cases. Two views should be reserved for cases where the NDT position cannot be

    Analysis of spacecraft to ground communications link performance and a description of the Deep Space Network system is provided. Due to the tremendous distances involved in communicating between the spacecraft at the edge of our solar system and Earth, communications link performance is stretched to the limit of theoretical predictions. This is required in order to return the maximum amount of data possible during critical events such as planetary flybys. The link analysis provides a basis for the initial link design before spacecraft launch and performance prediction and monitoring during spacecraft flight. Additionally, it indicates what performance upgrades are required for mission extensions and new missions. Performance is improved through the use of a larger antenna collecting area, greater transmitter power, lower receiving system noise temperature and more sophisticated data coding schemes. The performance of the Deep Space Station configuration which serves as the ground portion of the communications link is assessed.

  18. The STAPL pView

    The Standard Template Adaptive Parallel Library (STAPL) is a C++ parallel programming library that provides a collection of distributed data structures (pContainers) and parallel algorithms (pAlgorithms) and a generic methodology for extending them to provide customized functionality. STAPL algorithms are written in terms of pViews, which provide a generic access interface to pContainer data by abstracting common data structure concepts. Briefly, pViews allow the same pContainer to present multiple interfaces, e.g., enabling the same pMatrix to be \\'viewed\\' (or used) as a row-major or column-major matrix, or even as a vector. In this paper, we describe the stapl pView concept and its properties. pViews generalize the iterator concept and enable parallelism by providing random access to, and an ADT for, collections of elements. We illustrate how pViews provide support for managing the tradeoff between expressivity and performance and examine the performance overhead incurred when using pViews. © 2011 Springer-Verlag Berlin Heidelberg.

    Full Text Available With CT (computed tomography chest gaining more importance as a diagnostic tool, chest X-ray especially the lateral view is taken less commonly nowadays. Besides CT chest is also proven to be superior to chest X-ray in patients with major blunt trauma. We are presenting a 68-year old male who was partially treated from outside for a left sided pneumonia. He came to our hospital because of persisting chest pain. Chest X-ray, frontal view (postero-anterior was almost normal except for a mild opacity in the left lower zone. CT scan of the chest revealed a fluid collection posteriorly enclosed within enhancing pleura. Chest X-ray, left lateral view showed a corresponding posterior pleural based opacity. We are presenting this case to highlight the importance of the lateral view of the chest X-ray. In selected cases there is still a role for the lateral view. With the three dimensional visualization provided by the CT, the lateral view of the chest may be easier to understand. Consequent to the initial diagnosis by CT further follow up can be done with the chest X-ray. In a limited way this mitigates unnecessary expenditure and more importantly prevents the patient from exposure to harmful radiation in the form of repeated CT.

    Violent media exposure has been associated with aggressive behavior, and it has been suggested that child health professionals counsel families on limiting exposure. Effective violence prevention counseling requires an understanding of norms regarding parental attitudes, practices, and influencing factors. Both theories of reasoned action and planned behavior emphasize that subjective norms and attitudes affect people's perceptions and intended behavior. Few data exist on violent television viewing and monitoring from a cross-section of families. By understanding the spectrum of parental attitudes, community-sensitive interventions for violence prevention can be developed. The objective of this study was to assess attitudes about and monitoring of violent television viewing from the perspective of parents. An anonymous self-report assisted survey was administered to a convenience sample of parents/guardians who visited child health providers at 3 sites: an urban children's hospital clinic, an urban managed care clinic, and a suburban private practice. The parent questionnaire included questions on child-rearing attitudes and practices and sociodemographic information. A total of 1004 adults who accompanied children for health visits were recruited for the study; 922 surveys were completed (participation rate: 92%). A total of 830 (90%) respondents were parents and had complete child data. Of the 830 respondents, 677 had questions on television viewing included in the survey and were the focus of this analysis. Seventy-five percent of families reported that their youngest child watched television. Of these, 53% reported always limiting violent television viewing, although 73% believed that their children viewed television violence at least 1 time a week. Among television viewers, 81% reported usually or always limiting viewing of sexual content on television and 45% reported usually or always watching television with their youngest child.

    1999-01-01

    In the world of computer-based data acquisition and control, the graphical interface program LabVIEW from National Instruments is so ubiquitous that in many ways it has almost become the laboratory standard. To date, there have been approximately fifteen books concerning LabVIEW, but Professor Essick's treatise takes on a completely different tack than all of the previous discussions. In the more standard treatments of the ways and wherefores of LabVIEW such as LabVIEW Graphical Programming: Practical Applications in Instrumentation and Control by Gary W. Johnson (McGraw Hill, NY 1997), the emphasis has been instructing the reader how to program LabVIEW to create a Virtual Instrument (VI) on the computer for interfacing to a particular instruments. LabVIEW is written in ''G'' a graphical programming language developed by National Instruments. In the past the emphasis has been on training the experimenter to learn ''G''. Without going into details here, ''G'' incorporates the usual loops, arithmetic expressions, etc., found in many programming languages, but in an icon (graphical) environment. The net result being that LabVIEW contains all of the standard methods needed for interfacing to instruments, data acquisition, data analysis, graphics, and also methodology to incorporate programs written in other languages into LabVIEW. Historically, according to Professor Essick, he developed a series of experiments for an upper division laboratory course for computer-based instrumentation. His observation was that while many students had the necessary background in computer programming languages, there were students who had virtually no concept about writing a computer program let alone a computer- based interfacing program. Thus the beginnings of a concept for not only teaching computer- based instrumentation techniques, but aiso a method for the beginner to experience writing a com- puter program. Professor Essick saw LabVIEW as the ''perfect environment in which to

  4. A broader view of justice.

    Science.gov (United States)

    Jecker, Nancy S

    2008-10-01

    In this paper I argue that a narrow view of justice dominates the bioethics literature. I urge a broader view. As bioethicists, we often conceive of justice using a medical model. This model focuses attention at a particular point in time, namely, when someone who is already sick seeks access to scarce or expensive services. A medical model asks how we can fairly distribute those services. The broader view I endorse requires looking upstream, and asking how disease and suffering came about. In contrast to a medical model, a social model of justice considers how social determinants affect the health of a population. For example, social factors such as access to clean drinking water, education, safe workplaces, and police protection, profoundly affect risk for disease and early death. I examine one important social determinant of health, health care coverage, to show the limits of a medical model and the merits of a broader view.

  5. View synthesis using parallax invariance

    Science.gov (United States)

    Dornaika, Fadi

    2001-06-01

    View synthesis becomes a focus of attention of both the computer vision and computer graphics communities. It consists of creating novel images of a scene as it would appear from novel viewpoints. View synthesis can be used in a wide variety of applications such as video compression, graphics generation, virtual reality and entertainment. This paper addresses the following problem. Given a dense disparity map between two reference images, we would like to synthesize a novel view of the same scene associated with a novel viewpoint. Most of the existing work is relying on building a set of 3D meshes which are then projected onto the new image (the rendering process is performed using texture mapping). The advantages of our view synthesis approach are as follows. First, the novel view is specified by a rotation and a translation which are the most natural way to express the virtual location of the camera. Second, the approach is able to synthesize highly realistic images whose viewing position is significantly far away from the reference viewpoints. Third, the approach is able to handle the visibility problem during the synthesis process. Our developed framework has two main steps. The first step (analysis step) consists of computing the homography at infinity, the epipoles, and thus the parallax field associated with the reference images. The second step (synthesis step) consists of warping the reference image into a new one, which is based on the invariance of the computed parallax field. The analysis step is working directly on the reference views, and only need to be performed once. Examples of synthesizing novel views using either feature correspondences or dense disparity map have demonstrated the feasibility of the proposed approach.

    The plastic effect is historically used to denote various forms of stereopsis. The vivid impression of depth often associated with binocular stereopsis can also be achieved in other ways, for example, using a synopter. Accounts of this go back over a hundred years. These ways of viewing all aim to diminish sensorial evidence that the picture is physically flat. Although various viewing modes have been proposed in the literature, their effects have never been compared. In the current study, we...

  7. A prospective view of radioprotection

    Barescut, Jean C.

    2008-01-01

    Full text: If we exclude the specific case of medical radioprotection and workers radioprotection, the main challenge of tomorrow radioprotection is the protection of usual people faced to a possible increase of ambient contamination, either as a consequence of usual releases of industry or as a consequence of sporadic accidents. From the view points of regulators and practitioners of radioprotection, we have to optimize today researches and studies, to optimize protection investments and to prepare future rules according to what could be the possible concerns of radioprotection in a near future. Clearly, when dealing with nuclear energy, a perspective of 30 years is not a very far one. A nuclear plant built today will still be in operation 30 years from now. But 30 years is a fairly long time compared to evolutions of science. For example, DNA was discovered in 1953 and gene engineering began seriously in the years 70s. There is no doubt that the evolution speed will not decrease and that the scientific situation will be quite different within 30 years. This could have many practical consequences. One is that the risk associated to radioactive stress could be better estimated, another is that precursors of a disease attributable to radioactivity will certainly be detected earlier and will allow cure to begin earlier. It is quite likely also that our ability to stimulate the natural defenses of organisms will improve. In an even more futuristic approach, the use of nanoengines or the use of highly selective killer processes at the cell level seems quite possible. Radioprotection will not only be influenced by science but also by the level of environmental threats. We have already a pretty good backward knowledge but, if we consider that the real beginning of industrial nuclear age was in the seventies, within 30 years, we will have more than 70 years of retrospective view. That should be enough to determine if our exposure to radioactivity is really increasing

    Masturbation is the stimulation of sexual organs usually to the point of orgasm with an essential autoerotic component. Due to the high prevalence of this sexual behavior, it was and still is a matter of debate if masturbation is a normal action without any side effects and even if it is advantageous or it is associated with side effects necessitating public education how to avoid it. In addition, it is a common question if masturbation is religiously lawful or not. In this study, I assess the results of scientific studies about this sexual behavior and also shed some light on the Islam's view about it.

    Several innovative fusion concepts have recently been proposed with the intent of improving radically the attractiveness of fusion energy. Before their assessment is complete, however, the question of what constitutes an especially attractive fusion product should be examined from multiple viewpoints. The primary purpose of this paper is to examine views of potentially attractive fusion concepts from three perspectives, trying to determine commonalities. These viewpoints are (a) economics, (b) maintenance and reliability, and (c) safety and environment. The secondary purpose of the paper is to review some innovative concepts from these viewpoints

    2013-11-01

    This study examined if parental TV viewing, parental self-efficacy or access to media equipment were associated with TV viewing among UK preschool-aged children. Data were derived from a cross-sectional survey of 252 parents of 3-5-year-old children. Parents reported child and parent TV viewing and the number of TVs, DVDs, computers, games consoles, hand-held games consoles, music players and laptop computers in the home. Parents also completed scales which assessed their self-efficacy to limit the screen viewing (SV) and promote the physical activity (PA) and their own PA self-efficacy. Analysis indicated that around two thirds of the children spent two or more hours per day watching TV while 75 % of parents watched ≥ 2 h of TV per day. Logistic regression models showed that children who had a parent who watched ≥ 2 h of TV per day were over five times more likely to also watch ≥ 2 h of TV per day. Each unit increase in parental self-efficacy to limit SV was associated with a 77 % reduction in the likelihood that the child watched ≥ 2 h of TV per day. Each additional piece of media equipment in the home was associated with a 28 % increase in the likelihood that parents watched ≥ 2 h of TV per day. Family-based interventions focusing on changing access to home media equipment and building parental self-efficacy to reduce child TV viewing could form part of efforts to reduce TV viewing among preschool children.

    Full Text Available We investigated the impact of viewing versus not viewing a real forest on human subjects’ physiological and psychological responses in the same setting. Fifteen healthy volunteers (11 males, four females, mean age 36 years participated. Each participant was asked to view a forest while seated in a comfortable chair for 15 min (Forest condition vs. sitting the same length of time with a curtain obscuring the forest view (Enclosed condition. Both conditions significantly decreased blood pressure (BP variables, i.e., systolic BP, diastolic BP, and mean arterial pressure between pre and post experimental stimuli, but these reductions showed no difference between conditions. Interestingly, the Forest viewing reduced cerebral oxygenated hemoglobin (HbO2 assessed by near-infrared spectroscopy (NIRS and improved the subjects’ Profile of Mood States (POMS scores, whereas the Enclosed condition increased the HbO2 and did not affect the POMS scores. There were no significant differences in saliva amylase or heart rate variability (HRV between the two conditions. Collectively, these results suggest that viewing a real forest may have a positive effect on cerebral activity and psychological responses. However, both viewing and not viewing the forest had similar effects on cardiovascular responses such as BP variables and HRV.

  12. Occlusion-Aware View Interpolation

    Full Text Available View interpolation is an essential step in content preparation for multiview 3D displays, free-viewpoint video, and multiview image/video compression. It is performed by establishing a correspondence among views, followed by interpolation using the corresponding intensities. However, occlusions pose a significant challenge, especially if few input images are available. In this paper, we identify challenges related to disparity estimation and view interpolation in presence of occlusions. We then propose an occlusion-aware intermediate view interpolation algorithm that uses four input images to handle the disappearing areas. The algorithm consists of three steps. First, all pixels in view to be computed are classified in terms of their visibility in the input images. Then, disparity for each pixel is estimated from different image pairs depending on the computed visibility map. Finally, luminance/color of each pixel is adaptively interpolated from an image pair selected by its visibility label. Extensive experimental results show striking improvements in interpolated image quality over occlusion-unaware interpolation from two images and very significant gains over occlusion-aware spline-based reconstruction from four images, both on synthetic and real images. Although improvements are obvious only in the vicinity of object boundaries, this should be useful in high-quality 3D applications, such as digital 3D cinema and ultra-high resolution multiview autostereoscopic displays, where distortions at depth discontinuities are highly objectionable, especially if they vary with viewpoint change.

Then, disparity for each pixel is estimated from different image pairs depending on the computed visibility map. Finally, luminance/color of each pixel is adaptively interpolated from an image pair selected by its visibility label. Extensive experimental results show striking improvements in interpolated image quality over occlusion-unaware interpolation from two images and very significant gains over occlusion-aware spline-based reconstruction from four images, both on synthetic and real images. Although improvements are obvious only in the vicinity of object boundaries, this should be useful in high-quality 3D applications, such as digital 3D cinema and ultra-high resolution multiview autostereoscopic displays, where distortions at depth discontinuities are highly objectionable, especially if they vary with viewpoint change.

  14. CRISM Views Phobos and Deimos

    Science.gov (United States)

    2007-01-01

    chondrites are primitive carbon-containing materials thought to originate in the outer part of the asteroid belt. This led to a commonly held view among planetary scientists that Mars' moons are primitive asteroids captured into Martian orbit early in the planet's history. More recent measurements have shown that the moons are in fact relatively red in their color, and resemble even more primitive D-type asteroids in the outer solar system. Those ultra-primitive bodies are also thought to contain carbon as well as water ice, but to have experienced even less geochemical processing than many carbonaceous chondrites. The version of the CRISM images shown here were constructed by displaying 0.90, 0.70, and 0.50 micrometer wavelengths in the red, green, and blue image planes. This is a broader range of colors than is visible to the human eye, but it accentuates color differences. Both moons are shown with colors scaled in the same way. Deimos is red-colored like most of Phobos. However, Phobos' surface contains a second material, grayer-colored ejecta from a 9-kilometer (5.6-mile) diameter crater. This crater, called Stickney, is located at the upper left limb of Phobos and the grayer-colored ejecta extends toward the lower right. These CRISM measurements are the first spectral measurements to resolve the disk of Deimos, and the first of this part of Phobos to cover the full wavelength range needed to assess the presence of iron-, water-, and carbon-containing minerals. CRISM is one of six science instruments on NASA's Mars Reconnaissance Orbiter. Led by The Johns Hopkins University Applied Physics Laboratory, Laurel, Md., the CRISM team includes expertise from universities, government agencies and small businesses in the United States and abroad. NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the Mars Reconnaissance Orbiter and the Mars Science Laboratory for NASA's Science Mission Directorate, Washington.

    The purpose of this study was to compare two methods of combining tomosynthesis with digital mammography by assessing diagnostic accuracy and recall rates for digital mammography alone and digital mammography combined with one-view tomosynthesis and two-view tomosynthesis. Three hundred ten cases including biopsy-proven malignancies (51), biopsy-proven benign findings (47), recalled screening cases (138), and negative screening cases (74) were reviewed by 15 radiologists sequentially using digital mammography, adding one-view tomosynthesis, and then two-view tomosynthesis. Cases were assessed for recall and assigned a BI-RADS score and probability of malignancy for each imaging method. Diagnostic accuracy was assessed using receiver operating characteristic (ROC) analysis. Screening recall rates were compared using pooled logistical regression analysis. A p value of tomosynthesis, and DM plus two-view tomosynthesis was 0.828, 0.864, and 0.895, respectively. Both one-view and two-view tomosynthesis plus DM were significantly better than DM alone (Δ AUCs 0.036 [p = 0.009] and 0.068 [p tomosynthesis, and DM plus two-view tomosynthesis were 44.2%, 27.2%, and 24.0%, respectively. Combined with DM, one-view and two-view tomosynthesis both showed significantly lower noncancer recall rates than digital mammography alone (p tomosynthesis showed a significantly lower recall rate than digital mammography with one-view tomosynthesis (p tomosynthesis compared with digital mammography alone. Compared with digital mammography, diagnostic sensitivity for invasive cancers increased with the addition of both one-view (Δ12.0%, p tomosynthesis. The addition of one-view tomosynthesis to conventional digital mammography improved diagnostic accuracy and reduced the recall rate; however, the addition of two-view tomosynthesis provided twice the performance gain in diagnostic accuracy while further reducing the recall rate.

  20. A broad view of model validation

    International Nuclear Information System (INIS)

    Tsang, C.F.

    1989-10-01

    The safety assessment of a nuclear waste repository requires the use of models. Such models need to be validated to ensure, as much as possible, that they are a good representation of the actual processes occurring in the real system. In this paper we attempt to take a broad view by reviewing step by step the modeling process and bringing out the need to validating every step of this process. This model validation includes not only comparison of modeling results with data from selected experiments, but also evaluation of procedures for the construction of conceptual models and calculational models as well as methodologies for studying data and parameter correlation. The need for advancing basic scientific knowledge in related fields, for multiple assessment groups, and for presenting our modeling efforts in open literature to public scrutiny is also emphasized. 16 refs

Evaluation criteria and standards with a view to effective precautionary care of the environment; Die Bewertung der Luftqualitaet bei Umweltvertraeglichkeitspruefungen.

    1994-12-31

    Since the beginning of the debate surrounding the environmental impact statement in Germany, opinion is divided over what yardsticks should be applied in assessing a scheme`s environmental impact, and what consequences they involve for the environment. This book is a comprehensive compilation of air quality standards by substances and objects of protection containing a definition of the term ``active precautionary care of the environment`` as mentioned in section 1 of the act on environmental impact statements (UVPG). The reasons that the book is important for day-to-day work with environmental impact statements lie, for one thing, in its technical relevance and, for the other, in the fact that the proposed assessment criteria are legally unobjectionable. The book stakes out the legal boundaries, points out differentiated criteria for the definition of standards, selects relevant substances, explains the procedure in defining standards and the evaluation grid used, demonstrates how the standards are applied, and contains a tabulated summary. Part two of the book deals with the investigated compounds and groups of compounds. (orig./HP) [Deutsch] Seit der UVP-Debatte in Deutschland ist strittig, welcher Massstab bei der Beurteilung der Umweltvertraeglichkeit einer Massnahme anzulegen ist und wie deren Umweltauswirkungen zu bewerten sind.

    2018-03-01

    Full Text Available Background: With the integration of various targeted therapies into the clinical management of patients with advanced lung adenocarcinoma, next-generation sequencing (NGS has become the technology of choice and has led to an increase in simultaneously interrogated genes. However, the broader adoption of NGS for routine clinical practice is still hampered by sophisticated workflows, complex bioinformatics analysis and medical interpretation. Therefore, the performance of the novel QIAGEN GeneReader NGS system was compared to an in-house ISO-15189 certified Ion PGM NGS platform. Methods: Clinical samples from 90 patients (60 Retrospectively and 30 Prospectively with lung adenocarcinoma were sequenced with both systems. Mutations were analyzed and EGFR, KRAS, BRAF, NRAS, ALK, PIK3CA and ERBB2 genes were compared and sampling time and suitability for clinical testing were assessed. Results: Both sequencing systems showed perfect concordance for the overlapping genes. Correlation of allele frequency was r2 = 0.93 for the retrospective patients and r2 = 0.81 for the prospective patients. Hands-on time and total run time were shorter using the PGM system, while the GeneReader platform provided good traceability and up-to-date interpretation of the results. Conclusion: We demonstrated the suitability of the GeneReader NGS system in routine practice in a clinical pathology laboratory setting.

  18. Radiologic analysis of hindfoot alignment: Comparison of Méary, long axial, and hindfoot alignment views.

    Neri, T; Barthelemy, R; Tourné, Y

    2017-12-01

    Among radiographic views available for assessing hindfoot alignment, the antero-posterior weight-bearing view with metal cerclage of the hindfoot (Méary view) is the most widely used in France. Internationally, the long axial view (LAV) and hindfoot alignment view (HAV) are used also. The objective of this study was to compare the reliability of these three views. The Méary view with cerclage of the hindfoot is as reliable as the LAV and HAV for assessing hindfoot alignment. All three views were obtained in each of 22 prospectively included patients. Intra-observer and inter-observer reliabilities were assessed by having two observers collect the radiographic measurements then computing the intra-class correlation coefficients (ICCs). The intra-observer and inter-observer ICCs were 0.956 and 0.988 with the Méary view, 0.990 and 0.765 with the HAV, and 0.997 and 0.991 with the LAV, respectively. Correlations were far stronger between the LAV and HAV than between each of these and the Méary view. Compared to the LAV and HAV, the Méary view indicated a greater degree of hindfoot valgus. Intra-observer reliability was excellent with both the LAV and HAV, whereas inter-observer reliability was better with the LAV. Excellent reliability was also obtained with the Méary view. Combining the Méary view to obtain a radiographic image of the clinical deformity with the LAV to measure the angular deviation of the hindfoot axis may be useful when assessing hindfoot malalignment. A comparison of the three views in a larger population is needed before clinical recommendations can be made. II, prospective study. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

    This paper investigates the view update problem for XML views published from relational data. We consider XML views defined in terms of mappings directed by possibly recursive DTDs compressed into DAGs and stored in relations. We provide new techniques to efficiently support XML view updates...... specified in terms of XPath expressions with recursion and complex filters. The interaction between XPath recursion and DAG compression of XML views makes the analysis of the XML view update problem rather intriguing. Furthermore, many issues are still open even for relational view updates, and need...... to be explored. In response to these, on the XML side, we revise the notion of side effects and update semantics based on the semantics of XML views, and present effecient algorithms to translate XML updates to relational view updates. On the relational side, we propose a mild condition on SPJ views, and show...

Métodos: Mapeo por multicriterios, en el marco del proyecto europeo Opciones de Políticas para Responder al Desafío de la Obesidad (PorGrow, mediante una entrevista estructurada individual a 21 actores principales, líderes del sector público y privado en la alimentación y el ejercicio físico en España. Se integró en el análisis información de tipo cuantitativo y cualitativo. Los entrevistados justificaron sus posiciones en pro y en contra de las diferentes iniciativas de políticas, aspectos que se denominaron «criterios», que fueron ponderados según su importancia relativa y documentados mediante textos y «perlas» del discurso de los entrevistados. Resultados: Se identificaron 93 argumentos para la selección de políticas en los 21 entrevistados. Los argumentos más utilizados y valorados por su importancia fueron: eficacia (n = 18, beneficios sociales (n = 17 y aceptabilidad social (n = 14. Los costes económicos fueron considerados poco relevantes tanto para el sector público como para los individuos. El impacto económico para el sector comercial no fue incluido por ninguno de los entrevistados. Según el área de actuación, los criterios más relevantes fueron la eficacia y los beneficios sociales, para el sector privado y público, respectivamente. Conclusiones: Quizá porque España se encuentra al comienzo del proceso de desarrollo de políticas de obesidad y aún no hay ni «ganadores» ni «perdedores» entre los afectados, los costes financieros aparecen como una cuestión de bajo perfil para los entrevistados, lo que abre una ventana de oportunidad para ensayar políticas de regulación.Aim: To explore the criteria used to assess public policy initiatives on obesity in Spain by the main stakeholders.

  9. World View in Economic Science

    Directory of Open Access Journals (Sweden)

    Kyzym Mykola O.

    2017-09-01

    Full Text Available In the process of updating the economic model of society there arose the problem of eliminating contradictions in the development of economic science that do not allow us to solve problems of practice in proven ways. Although these contradictions and methods for their resolving are partially reflected in many scientific publications, methodological and practical justifications for a comprehensive study of the reserves of the economic science development by combining the provisions of philosophy and disciplines of the humanities are still relevant. The solution of the problem of unpredictability of functioning and development of the economy using such a combination of scientific disciplines can be ensured by applying the world view models that enable justifying the vector of attention of scientists in the subject area of the problem. The constructiveness of the interaction of scientists representing different ontological views of the world depends on improving of the conceptual and categorical support of their dialogue. A scientific world view in such a composition creates a basis, firstly, for a fruitful discussion of representatives of various disciplines having a common subject of research, and, secondly, for overcoming the institutional and cognitive barriers to professional mobility of scientists. It can also serve to develop the mobility of representatives of professional communities of researchers.

    To assess how drivers view dangers on the highway, what motivates them to drive safely, how they say they reduce their crash and injury risk, and how they rate their own driving skills. Most drivers rated their skills as better than average. The biggest motivating factor for safe driving was concern for safety of others in their vehicle, followed by negative outcomes such as being in a crash, increased insurance costs, and fines. The greatest threats to their safety were thought to be other drivers' actions that increase crash risk such as alcohol impairment or running red lights. In terms of reducing crashes and injuries, drivers tended to focus on actions they could take such as driving defensively or using seat belts. There was less recognition of the role of vehicles and vehicle features in crash or injury prevention. Knowing how drivers view themselves and others, their concerns, and their motivations and techniques for staying out of trouble on the roads provides insight into the difficulty of changing driving practices.

    Results are presented from a survey held among 1868 scientists studying various aspects of climate change, including physical climate, climate impacts, and mitigation. The survey was unique in its size, broadness and level of detail. Consistent with other research, we found that, as the level of expertise in climate science grew, so too did the level of agreement on anthropogenic causation. 90% of respondents with more than 10 climate-related peer-reviewed publications (about half of all respondents), explicitly agreed with anthropogenic greenhouse gases (GHGs) being the dominant driver of recent global warming. The respondents' quantitative estimate of the GHG contribution appeared to strongly depend on their judgment or knowledge of the cooling effect of aerosols. The phrasing of the IPCC attribution statement in its fourth assessment report (AR4)-providing a lower limit for the isolated GHG contribution-may have led to an underestimation of the GHG influence on recent warming. The phrasing was improved in AR5. We also report on the respondents' views on other factors contributing to global warming; of these Land Use and Land Cover Change (LULCC) was considered the most important. Respondents who characterized human influence on climate as insignificant, reported having had the most frequent media coverage regarding their views on climate change.

    The use of combustor diagnostics is considered from the point of view of demonstration of performance of an airbreathing hypersonic engine. The basic need is seen to be that of providing the data necessary to verify performance predictions for the engine as installed in the airplane. This necessitates the use of a diagnostics capability that can provide the inputs required by the computational analyses that will be used to assess this performance. Because of the cost of ground test facilities, a premium is placed on measurement technique reliability and redundancy of instrumentation. A mix of nonintrusive optical techniques and probe-based measurements is seen to be the best approach using current diagnostics capability; one such instrument mix is outlined for a ramjet/scramjet test program. 11 references

    Aim: Bone Mineral Density (BMD) measurement is an invaluable technique for assessing fracture risk in suspected cases of osteoporosis. The routine procedure includes AP spine and hip views. But quite often there are discordant results between them, bone mineral concentration (BMC) in the AP spine appears higher than hip. Our study was done to establish the importance of lateral spine view. The lateral view would provide better scope to draw the ROI perfectly and so BMC would be more accurately measured. Materials and Methods: In a prospective study a total of 60 consecutive patients (48F, 12M) were evaluated for bone densitometric measurements. The age group was 35 - 80 years (Mean 59 years). None of the patients received estrogen, biphosphonates or steroid therapy. Bone density of the hip and lumbar spine were measured with Norland XR 36. The T-score, which measures the difference between patient's BMD and young-normal was computed and age-matched Z-score were calculated. X-ray correlation was also done in most of the cases. Results: When we analyzed the femoral neck values, 30 cases were osteoporotic and 23 were osteopenic whereas according to AP spine views only 20 were osteoporotic and 30 were osteopenic. So, clearly a significant number of patients having osteoporosis were interpreted as osteopenia (P 0.05). But in the same vertebra there were significant differences (P<0.05) of BMC measured with AP and lateral views. Conclusion: The lateral view can exclude the posterior element of the vertebra as well as the aorta anteriorly, where a high incidence of calcified atherosclerotic plaques are present. AP view includes these drawbacks resulting in falsely higher BMC. Lateral spine view can eliminate these problems and so it provides an important role in BMD measurements. The authors recommend that it should be included in routine practice

    Pharmacogenomics has an important role in the evolution of personalized medicine, and its widespread uptake may ultimately depend on the interests and perspectives of key players in health care. Our aim was to summarize studies on stakeholder perspectives and attitudes toward pharmacogenomic testing. Thus, we conducted a review of original research studies that reported stakeholder views on pharmacogenomic testing using a structured approach in PubMed, International Pharmaceutical Abstracts, Cumulative Index to Nursing and Allied Health Literature, and EMBASE. A standardized data abstraction form was developed that included stakeholder group of interest-patients, general public, providers, and payers. Stakeholder views regarding barriers to pharmacogenetic implementation were organized into the following themes: ancillary information-related, clinical, economic, educational, ethical or legal, medical mistrust, and practicality. Of 34 studies that met our inclusion criteria, 37 perspectives were reported (15 on providers, 9 on the general public, 9 on patients, and 4 on payers). The most common topics that arose in studies of providers related to clinical usefulness of genetic data (n=11) and educational needs (n=11). Among the general public, the most common concerns were medical mistrust (n=5), insufficient education (n=5), and practicality (n=5). The most prevalent issues from the patient perspective were ethical or legal (n=6) and economic (n=5) issues. Among payers, leading issues were practicality (n=4) and clinical usefulness (n=3). There was overlap in the topics and concerns across stakeholder perspectives, including lack of knowledge about pharmacogenomic testing. Views on issues related to privacy, cost, and test result dissemination varied by stakeholder perspective. Limited research had been conducted in underrepresented groups. Efforts to address the issues raised by stakeholders may facilitate the implementation of pharmacogenomic testing into

    Beginning in 1960 two serious radiation exposure problems (occupational exposure in uranium mines and population exposure from testing of nuclear weapons) came to the attention. One might have expected ICRP to be the first to try to reduce these exposures but it was conspicuous by its silence. In 1958 ICRP set limits of exposure for radiation workers and members of the public. Nineteen years later (1977) when it was realized that the risk of radiation induced cancer was ten to thirty times what it was estimated to be in 1958, ICRP might have been expected to recommend a significant reduction in permissible exposure levels, but to the dismay of some it increased them. It was also a great disappointment when in 1977, levels of maximum permissible concentration of radionuclides in air, water and food were increased for a large fraction of the more dangerous radionuclides. The reactor accident at Chernobyl calls for a number of new ICRP recommendations [fr

    The concepts of risk perception and risk management are discussed within the context of an analysis of the comparative risks of power production arising from the use of different energy sources, with especial reference to nuclear power. The benefits of energy use, risk reduction and regulation are examined. It is felt that the question to be answered is not whether a specific energy source is too dangerous to use but rather whether the costs of making it safe enough are so high that it is uneconomic. Energy policy should not be significantly affected by the risks of producing and distributing energy though it may be influenced by people's fear of those risks. (U.K.)

    1980-01-01

    The global breeding gain (GBC), which may be divided into internal breeding gain (IBG) and external breeding gain (EGB), is dealt with for mixed oxide fuelled LMFBR. Relative contributions of core and blankets to GBG are indicated for three power levels (250, 500 and 1200 MWe). Reactor physics studies are performed to reduce uncertainties on GBC. The studies are of three types, depending on countries. The mock-up approach consists of measuring on one critical assembly, typical of the considered power reactor, the GBG at one time of life of the plant, usually the beginning of life configuration (absorbers in) and trying to obtain bias factors. Parametric analysis of the neutron balance and data adjustment in which global parameters of the neutron balance are measured systematically is the approach followed in the UK and France for all configurations of the reactor, especially for integral parameters related to GBG. Analysis of irradiated fuels involves the measurements of the variation of fuel isotopic compositions versus burn-up with two main goals: accurate measurement of captive ratios and global check of the GBG calculation.

    Viewing time tasks using still pictures to assess age and gender sexual interests have been well validated and are commonly used. The use of film clips in a viewing time task would open up interesting possibilities for the study of sexual interest toward sexual targets or activities that are not easily captured in still pictures. We examined the validity of a viewing time task using film clips to assess sexual interest toward male and female targets, in a sample of 52 young adults. Film clips produced longer viewing times than still pictures. For both men and women, the indices derived from the film viewing time task were able to distinguish individuals who identified as homosexual (14 men, 8 women) from those who identified as heterosexual (15 men, 15 women), and provided comparable group differentiation as indices derived from a viewing time task using still pictures. Men's viewing times were more gender-specific than those of women. Viewing times to film clips were correlated with participants' ratings of sexual appeal of the same clips, and with viewing times to pictures. The results support the feasibility of a viewing time measure of sexual interest that utilizes film clips and, thus, expand the types of sexual interests that could be investigated (e.g., sadism, biastophilia).

    1989-01-01

    The report presents by way of introduction radiation protection criteria applied to radiological activities and to disposal of low-level and intermediate-level radioactive waste. In these cases it is primarily short-range views that are relevant, up to a few thousand years as a maximum. In the case of high-level wastes where the views may extend to more than hundreds of thousands years, there are not for the present any equally well stablished criteria. Based upon preliminary results from a Nordic team for criteria for high-level radioactive wastes, dose estimates in the long-range view and alternative assessment criteria are discussed. Proposals are also presented for 12 criteria that may be applicable. As the work is not yet finshed, the criteria are however merely preliminary

    The proposed talk would present the results of 2016 survey of American Geophysical Union members (n = 2040) about public engagement. This survey took place as part of a broader, NSF funded, study of engagement views across eight different U.S.-based scientific societies. The presentation would include data about geophysicists' past engagement behavior and willingness to engage alongside data about engagement attitudes, perceived norms (i.e. beliefs about whether peers engage and value engagement), and perceived efficacy (i.e., scientists' beliefs about their own communication skills and the impact of engagement). The presentation would also include results that describe scientists' overall goals for engagement (e.g., increasing support for specific policy positions, changing citizen behavior, etc.), as well as their communication-specific objectives (e.g., increasing knowledge, increase excitement, etc.). All of the results would be put in the context of equivalent results from scientists from seven other societies across a variety of fields, including chemistry, biology, and the social sciences. Three themes that would be emphasized in the presentation include (1) the fact that there are substantial commonalities in engagement views across scientific fields, (2) the important role that perceived engagement skill (efficacy) appears to play in predicting engagement willingness, and (3) a lack of evidence that scientists are thinking about engagement in strategic ways. Strategic engagement, in this regard, would involve setting clear goals and then choosing activities that the social science of science communication suggests might allow one to achieve those goals. The presentation would conclude with thoughts about what might be done to improve the effectiveness of science communication training.

    International Nuclear Information System (INIS)

    1996-09-01

    In July 1994, the Executive Director for Operations of the US Nuclear Regulatory Commission (NRC) appointed a Special Review Panel to assess the Differing Professional View or Opinion (DPV/DPO) process, including its effectiveness, how well it is understood by employees, and the organizational climate for having such views aired and properly decided. An additional area within this review was to address the effectiveness of the DPO procedures as they pertain to public access and confidentiality. Further, the Panel was charged with the review of the submittals completed since the last review to identify employees who made significant contributions to the agency or to the public health and safety but had not been adequately recognized for this contribution. The report presents the Special Review Panel's evaluation of the NRC's current process for dealing with Differing Professional Views or Opinions. Provided in this report are the results of an employee opinion survey on the process; highlights and suggestions from interviews with individuals who had submitted a Differing Professional View or Opinion, as well as with agency managers directly involved with the Differing Professional Views or Opinions process; and the Special Review Panel's recommendations for improving the DPV/DPO process

    Anteroposterior, lateral, and right and left oblique lumbar spine radiographs are often a standard part of the evaluation of children who are clinically suspected of having spondylolysis. Recent concerns regarding radiation exposure and costs have brought the value of oblique radiographs into question. The purpose of the present study was to determine the diagnostic value of oblique views in the diagnosis of spondylolysis. Radiographs of fifty adolescents with L5 spondylolysis without spondylolisthesis and fifty controls were retrospectively reviewed. All controls were confirmed not to have spondylolysis on the basis of computed tomographic scanning, magnetic resonance imaging, or bone scanning. Anteroposterior, lateral, and right and left oblique radiographs of the lumbar spine were arranged into two sets of slides: one showing four views (anteroposterior, lateral, right oblique, and left oblique) and one showing two views (anteroposterior and lateral only). The slides were randomly presented to four pediatric spine surgeons for diagnosis, with four-view slides being presented first, followed by two-view slides. The slides for twenty random patients were later reanalyzed in order to calculate of intra-rater agreement. A power analysis demonstrated that this study was adequately powered. Inter-rater and intra-rater agreement were assessed on the basis of the percentage of overall agreement and intraclass correlation coefficients (ICCs). PCXMC software was used to generate effective radiation doses. Study charges were determined from radiology billing data. There was no significant difference in sensitivity and specificity between four-view and two-view radiographs in the diagnosis of spondylolysis. The sensitivity was 0.59 for two-view studies and 0.53 for four-view studies (p = 0.33). The specificity was 0.96 for two-view studies and 0.94 for four-view studies (p = 0.60). Inter-rater agreement, intra-rater agreement, and agreement with gold-standard ICC values

    The prominent linear feature straight down the center of this perspective view is California's famous San Andreas Fault. The image, created with data from NASA's Shuttle Radar Topography Mission (SRTM), will be used by geologists studying fault dynamics and landforms resulting from active tectonics. This segment of the fault lies west of the city of Palmdale, Calif., about 100 kilometers (about 60 miles) northwest of Los Angeles. The fault is the active tectonic boundary between the North American plate on the right, and the Pacific plate on the left. Relative to each other, the Pacific plate is moving away from the viewer and the North American plate is moving toward the viewer along what geologists call a right lateral strike-slip fault. Two large mountain ranges are visible, the San Gabriel Mountains on the left and the Tehachapi Mountains in the upper right. Another fault, the Garlock Fault lies at the base of the Tehachapis; the San Andreas and the Garlock Faults meet in the center distance near the town of Gorman. In the distance, over the Tehachapi Mountains is California's Central Valley. Along the foothills in the right hand part of the image is the Antelope Valley, including the Antelope Valley California Poppy Reserve. The data used to create this image were acquired by SRTM aboard the Space Shuttle Endeavour, launched on February 11, 2000.This type of display adds the important dimension of elevation to the study of land use and environmental processes as observed in satellite images. The perspective view was created by draping a Landsat satellite image over an SRTM elevation model. Topography is exaggerated 1.5 times vertically. The Landsat image was provided by the United States Geological Survey's Earth Resources Observations Systems (EROS) Data Center, Sioux Falls, South Dakota.SRTM uses the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space Shuttle Endeavour

    Purpose: To retrospectively assess the diagnostic sensitivity of 45° Dunn view and cross-table lateral radiographs for the assessment of cam deformity by comparison with radial MRI. Materials and methods: 60 cases with radiographs (38 a–p and 45° Dunn views, 22 a–p and cross-table lateral views) and radial MRI were assessed. Alpha angle measurements were obtained both for radiographs and radial MRI. Statistics included frequency analysis, bivariate linear correlation analyses of MRI and radiograph measurements and cross-table analyses testing for the sensitivity and specificity of radiographs for the detection of an alpha angle larger than 55°. Results: 53.3% had the maximum alpha angle in the superior–anterior aspect of the femoral head–neck junction. Cam deformity was found in 45/60 cases (75%) in radial MRI. Pearson correlation demonstrated the Dunn view was most accurate for the superior–anterior aspect (.772, P < .001). The cross-table lateral views were best suited for the anterior–superior aspect (.511, P < .05). The sensitivity for cam deformity in the Dunn view was 96.4% vs. 70.6% in the cross-table lateral view. Conclusion: The 45° Dunn view can improve the first line of impingement diagnostics. Radial MRI however remains indispensable for pre-operative planning and the evaluation of symptomatic cases without obvious deformity.

    The present article is aimed on comprehensive view of Swine flu. It was first isolated from pigs in 1930 in USA. Pandemic caused by H1N1 in 2009 brought it in limelight. Itís a viral respiratory disease caused by viruses that infects pigs, resulting in nasal secretions, barking cough, decreased appetite, and listless behavior. Swine virus consist of eight RNA strands, one strand derived from human flu strains, two from avian (bird) strains, and five from swine strains. Swine flu spreads from infected person to healthy person by inhalation or ingestion of droplets contaminated with virus while sneezing or coughing. Two antiviral agents have been reported to help prevent or reduce the effects of swine flu, flu shot and nasal spray. WHO recommended for pandemic period to prevent its future outbreaks through vaccines or non-vaccines means. Antiviral drugs effective against this virus are Tamiflu and Relenza. Rapid antigen testing (RIDT), DFA testing, viral culture, and molecular testing (RT-PCR) are used for its diagnosis in laboratory

    To explore recent Singapore nursing graduates' experience of and views about their career development and progress. The recruitment and retention of an adequate number of registered nurses is a continuing workforce issue in Singapore and other major cities. Survey of recent nursing graduates. Recent nursing graduates from the Bachelor programme (n = 147) were sent an individual survey; a response rate of 54% was achieved. Findings show that nurses rated their self-concept in a positive manner and were most satisfied (moderately to very) with helping patients and providing effective care, and the level of patient involvement. They were least satisfied (moderately to only a little) with prestige among the general medical community and the general public, hours of work, lifestyle factors and research opportunities. The following four factors were identified as significant impediments to career development; lack of support in the work place; perceived insufficient clinical career development opportunities; excessive work hours; and limited access to merit-based places in further education. Suggestions made to overcome perceived career development barriers are as follows: broad multifactorial healthcare system changes; decreased and more flexible working hours; and fairer access to further clinical and higher education. Results highlight the value clinical nurses place on having access to career development opportunities, merit-based further education and work place supports.

    Since the ancient times the usage of cosmological ideas in mythology and poetry has contributed to the formation and development of human's philosophical thought. It is believed that before the M. Mashtots's alphabet, ancient Armenians have expressed their astronomical knowledge through stone structures and rock art.In the Armenian reality, the cosmological views, the idea of the spherical shape of the Earth and information of other celestial bodies more vividly were manifested in the works of Movses Khorenatsi, David Anhaght (5th century) and Anania Shirakatsi (7th century).Anania Shirakatsi is an Armenian Astronomer, Mathematician, Philosopher, Geographer and Alchemist.The importance of his work is also noted by foreign authors and he was called 7th century Cosmologist, First Scientist of Armenia and Middival Astronomer. Shirakatsi's works are united in his comprehensive knowledge, his insight of the mind, the ability of combining and analyzing facts and his literature talent.His works have simultaneous historical, cosmic, geographical, religious, literary and mystical significance. In the present study we will show Anania Shirakatsi's cosmological ideas and observations.

  8. Contemporary views on selective mutism

    2016-01-01

    Full Text Available The aim of this paper is to review contemporary literature on selective mutism (SM, available in our language. The paper includes a contemporary definition of the disorder, previous studies of selective mutism, theories about its origin, and treatment. SM is a disorder that occurs in childhood, when a child's speech is selectively lacking in certain social situations. School is the context in which the disorder is typically manifested, which is why SM is often diagnosed only after children start school. The paper gives a historical account of changes in views on this disorder. Modern conceptions emphasize selective inability of children to spontaneously and successfully express themselves verbally. In researching SM, case studies on children who have selective mutism are most commonly published. Etiological factors are not precisely defined, and different conceptions give their interpretations depending on various theoretical frameworks. Some studies consistently indicate a relation between SM and social anxiety, and some with opposing behavior and delays in language development. Based on theoretical explanations of SM, psychological interventions (behavioral and cognitive-behavioral, psychodynamic and projective techniques, counseling and family therapy are created. Modern treatment of selective mutism includes an eclectic approach and emphasizes the role of teachers and school in general. Future studies should deepen the knowledge about selective mutism, specify the methodological procedure and stimulate the individualized treatment of children with SM.

    2014-01-01

    Full Text Available Background. It was hypothesized that television viewing is predictive of cardiometabolic risk. Moreover, people with hostile personality type may be more susceptible to TV-induced negative emotions and harmful health habits which increase occurrence of cardiometabolic risk. Purpose. The prospective association of TV viewing on cardiometabolic risk was examined along with whether hostile personality trait was a modifier. Methods. A total of 3,269 Black and White participants in the coronary artery risk development in young adults (CARDIA study were assessed from age 23 to age 35. A cross-lagged panel model at exam years 5, 10, 15, and 20, covering 15 years, was used to test whether hours of daily TV viewing predicted cardiometabolic risk, controlling confounding variables. Multiple group analysis of additional cross-lagged panel models stratified by high and low levels of hostility was used to evaluate whether the association was modified by the hostile personality trait. Results. The cross-lagged association of TV viewing at years 5 and 15 on clustered cardiometabolic risk score at years 10 and 20 was significant (B=0.058 and 0.051, but not at 10 to 15 years. This association was significant for those with high hostility (B=0.068 for exam years 5 to 10 and 0.057 for exam years 15 to 20 but not low hostility. Conclusion. These findings indicate that TV viewing is positively associated with cardiometabolic risk. Further, they indicate that hostility might be a modifier for the association between TV viewing and cardiometabolic risk.

    International Nuclear Information System (INIS)

    Shapiro, A.B.

    1988-01-01

    1 - Description of program or function: FACET calculates the radiation geometric view factor (alternatively called shape factor, angle factor, or configuration factor) between surfaces for axisymmetric, two-dimensional planar and three-dimensional geometries with interposed third surface obstructions. FACET was developed to calculate view factors as input data to finite element heat transfer analysis codes. 2 - Method of solution: Three algorithms are incorporated to integrate the view factor equation for three dimensional geometries. The algorithm used for any two surfaces depends on their geometric relationship and whether third surface obstructions exist. The three algorithms are the area integration (AI) method, the line integration method (LI), and the Mitalas and Stephenson (MS) method. The LI method is used to calculate the view factor between two disjoint surfaces. If the two surfaces have an adjoint edge, the MS method is used. The AI method is used if there is self or third surface shadowing. In two-dimensional planar geometries, the view factor between two surfaces is calculated using Hottel's cross string method. For axisymmetric geometries in the absence of shadowing, the view factor between two surfaces is calculated by view factor algebra using the view factors between parallel coaxial discs. In the presence of self or third surface shadowing, the geometry is represented in three dimensions before calculating the view factors

The CH2O-life connection is maintained as long as the supply of H and O lasts, which is in turn are provided by the splitting of the water molecule H2O. Water is split by electricity, as well-known from school-level experiments, and by solar radiation and geothermal heat on a global scale. In other words, the Sun’s radiation and the Earth’s heat as well as radioactivity split water to supply H and O for continued existence of life on the Earth. These photochemical, radiochemical and geothermal processes have influences on the evolution and current composition of the Earth’s atmosphere, compared with those of Venus and Mars, and influences on the planetary climatology. This view of life may be applicable to the “search-for-life in space” and to sustainability assessment of astrobiological habitats.

    The electric utilities consume almost 85% of the coal that is used in the US. The utilities as well as other industries will be seriously affected by revisions currently being considered to the Clean Air Act. We endorse the 10-year scientific National Acid Precipitation Assessment Program (NAPAP) which concludes the acid rain is not an environmental crisis but a long-term problem that needs to be addressed. The extreme views expressed by environmentalists and echoed by the media have been rendered unlikely to be correct assording to the NAPAP director. For example, the report found that the majority of North American forests are healthy. In addition, SO 2 emissions are down while coal use has doubled since the 70's. However, Congress, by considering any of the proposed Clean Air bills, is ignoring the NAPAP results. Experts from all areas are touting the need for the development of a National Energy Policy which would decrease our reliance on foreign oil and capitalize on the resources in abundance here in the United States -- like coal. The President has urged lawmakers to enact measures that would do just that. Yet the Joint Committee of Congress is marching on with revisions to a Clean Air Act that is already working. This will increase the cost of energy across all areas of industry and call a halt to the industrial recovery in this country

    To evaluate use of a caudoventral-craniodorsal oblique radiographic view made at 45° to the frontal plane (H view) for assessment of the pectoral (thoracic) girdle in raptors. Retrospective cross-sectional analysis. 24 raptors suspected to have a fracture of the thoracic girdle. Standard ventrodorsal and H views were obtained for all birds. Radiographs were evaluated twice by a radiologist blinded to the final diagnosis, with each view first evaluated independently and views then evaluated in combination. Sensitivity, specificity, positive predictive value, and negative predictive value were calculated, with results of surgery or necropsy used as the gold standard. 9 birds had thoracic girdle fractures; fractures were correctly identified in 8 of these 9 birds on the ventrodorsal view alone, 7 of these 9 birds on the H view alone, and all 9 birds on the 2 views in combination. Fifteen birds did not have thoracic girdle fractures; radiographs were correctly classified in 12 of these 15 birds when the ventrodorsal view was evaluated alone, all 15 birds when the H view was evaluated alone, and 14 of these 15 birds when the 2 views were evaluated in combination. Results suggested that the H view or the addition of the H view to the VD view could be useful in raptors suspected to have fractures of the thoracic girdle. Agreement with the gold standard (ie, fracture present or absent) was higher with the H view and combination of views than with the ventrodorsal view alone.

  3. Enhancing multi-view autostereoscopic displays by viewing distance control (VDC)

    Conventional multi-view displays spatially interlace various views of a 3D scene and form appropriate viewing channels. However, they only support sufficient stereo quality within a limited range around the nominal viewing distance (NVD). If this distance is maintained, two slightly divergent views are projected to the person's eyes, both covering the entire screen. With increasing deviations from the NVD the stereo image quality decreases. As a major drawback in usability, the manufacturer so far assigns this distance. We propose a software-based solution that corrects false view assignments depending on the distance of the viewer. Our novel approach enables continuous view adaptation based on the calculation of intermediate views and a column-bycolumn rendering method. The algorithm controls each individual subpixel and generates a new interleaving pattern from selected views. In addition, we use color-coded test content to verify its efficacy. This novel technology helps shifting the physically determined NVD to a user-defined distance thereby supporting stereopsis. The recent viewing positions can fall in front or behind the NVD of the original setup. Our algorithm can be applied to all multi-view autostereoscopic displays — independent of the ascent or the periodicity of the optical element. In general, the viewing distance can be corrected with a factor of more than 2.5. By creating a continuous viewing area the visualized 3D content is suitable even for persons with largely divergent intraocular distance — adults and children alike — without any deficiency in spatial perception.

    This study aimed to examine how physical activity (PA) and television (TV) viewing time of children varied according to family structure. In 2001, 5- to 6-yr-old (N = 296) and 10- to 12-yr-old (N = 919) children and their parents were recruited from 19 state elementary schools in Melbourne, Australia. Children's PA was objectively assessed using accelerometers worn for 8 d. Sociodemographic and family structure information and time spent watching TV was collected via questionnaire completed by parents. ANCOVA revealed that, after controlling for socioeconomic status and age of child, boys without any siblings spent more minutes per day watching TV (153.2 +/- 71.3) compared with those who have siblings (129.0 +/- 64.4, P s sex with PA and between number of siblings and sex with TV viewing. Family structure may be an important source of influence on children's PA and TV viewing time. Aspects of family structure interact differently with PA and TV viewing, suggesting interventions may need to be tailored with consideration of the family structure of children.

    The purpose of this article is to present findings from two parallel qualitative studies that used focus groups to explore adolescent views of psychological wellness and healthy bodies. Nine focus groups were held with 46 adolescents aged 16-19 years from two Mid-Western Canadian high schools. Both studies were designed with an interpretive humanist perspective and then a 6-step thematic approach was used to analyze the data. Common themes emerging in the focus group discussions in both studies included the negative impact of media on adolescent body image and pressure to conform to the Western views of physical appearance. These findings illustrate the need for nurses to understand the influence of the media on adolescents' views of their body image and to incorporate protocols for assessment, education, and counseling of adolescents on the healthy usage of media into their pediatric clinical practice. Through consistent participation in the development and implementation of health policies, nurses play a critical role in supporting adolescents to develop healthy views of body image.

    Rapid changes occurring within the Arctic heighten the need to understand the multiple drivers pushing change and their cumulative impacts. Most importantly to better understand Arctic change a holistic view is needed that can only be achieved through bringing together multiple knowledge systems and scientific disciplines. Inuit have called the Arctic home from time immemorial acquiring a knowledge system. The Inuit knowledge system continues to grow, and holds methodologies and assessment processes that provide a pathway for holistically understanding the Arctic. This holistic view is largely attributed to a focus on relationships between system components, close attention to food webs, and a unique understanding of interconnecting systems. The Alaskan Inuit understanding of food security represents an Indigenous way of viewing the world - where food security encompasses complex and interlinked cultural and environmental systems. These systems are comprised of connections among the health of people, animals, and plants; the different states of land, sea, and air; and the cultural fabric held together by language, cultural expression, and social integrity. Within the Inuit knowledge system, it is impossible to disentangle some of these relationships; when we discuss an Inuit food security perspective, it is this interconnectivity and these relationships that we refer to. This presentation will offer an introduction to what it means to adopt a food security lens approach - a view needed to build our knowledge of the changes that are occurring and further our understanding of cumulative impacts while illuminating the nexus between all pieces that make up Arctic ecosystems.

    Few studies have examined the effect of excess television (TV) viewing on specific mental health outcomes, such as self-esteem. We explored the cross-sectional association between TV viewing hours and self-esteem in young children. A total of 70,210 primary 4 (US grade 4) participants of the Department of Health Student Health Service, Hong Kong, in 1998-2000 reported TV viewing hours in a standardized questionnaire. Self-esteem was assessed using the Culture-Free Self-Esteem Inventories for Children (SEI) with 4 subscales. Multivariate linear regression yielded beta coefficients (β) for SEI subscale scores by TV hours, adjusting for age, sex, body mass index, lifestyle characteristics, and highest parental education and occupational status. Only 10.9% of children watched >4 hours per day, while 45.3% watched TV for 1 to ≤2 hours per day. Compared with children who watched Children who watched >2 hours of TV per day had lower SEI scores than those who watched self-esteem among young children. The development of self-esteem among children who report little or excessive TV viewing should be further studied.

    This image, generated using 16 orbits of MISR data collected between August 16 and August 30, 2000, takes us to the cradle of many civilizations. The data are from the 60-degree aftward-viewing camera. Because the individual orbit swaths are only 400 kilometers wide, they were 'mosaiced' together to form this composite picture, which covers about 2700 kilometers from west to east and 1750 kilometers from north to south. A few discontinuities are present in the mosaic, particularly near clouds, due to changes in the scene which occurred between dates when the individual orbit data were acquired.At the northern tip of the Red Sea, the Gulf of Suez and the Gulf of Aqaba frame the sandy deserts and spectacular mountains of the Sinai Peninsula. The highest peaks are Gebel Katherina (Mountain of St. Catherine, 2637 meters) and Gebel Musa (Mountain of Moses, also known as Mount Sinai, 2285 meters). To the northeast, Israel and Jordan flank the Dead Sea, one of the saltiest inland water bodies in the world. At its northern edge is Qumran, where the ancient Scrolls were discovered; the city of Jerusalem lies about 30 kilometers to the west.Several large rivers are prominent. Flowing southeastward through Iraq are the Tigris and Euphrates. The dark area between the two rivers, northwest of the Persian Gulf, is a very fertile region where fishing and farming are prevalent. Wending its way through eastern Egypt is the Nile. In the south is Lake Nasser and the Aswan Dam; continuing northward the Nile passes the Temple of Luxor as it sharply loops to the east. It then turns west and northward, eventually passing the capital city of Cairo, and finally spreading into a prominent delta as it empties into the Mediterranean Sea. The bright dot just west of the apex of the delta marks the location of the great Pyramids and Sphinx complexes on the Giza Plateau. On the coast, west of the delta, is the ancient city of Alexandria, Egypt's main seaport.'MISR', as it turns out, is the

    Safety has always been an important objective in nuclear technology. Starting with a set of sound physical principles and prudent design approaches, safety concepts have gradually been refined and cover now a wide range of provisions related to design, quality and operation. Research, the evaluation of operating experiences and probabilistic risk assessments constitute an essential basis and international co-operation plays a significant role in that context. Concerning future developments a major objective for new reactor concepts, such as the EPR, is to practically exclude a severe core damage accident with large scale consequences outside the plant.

    Ford, C; Ward, D; White, M

    2012-12-01

    The aim of this paper was to systematically review the evidence for the association between television viewing and diet in children ages 2-6. Data sources included PubMed, PsycINFO, EMBASE, ERIC, SportDISCUS, Sociological Abstracts, Web of Science and hand searches of reference lists of relevant articles. Twelve studies were reviewed in which the relationship between television viewing and diet was assessed in children between the ages of 2 and 6. All but one study reported significant relationship between television viewing time and adverse dietary outcomes. Parent-reported television viewing time was used to assay child television viewing in all included studies. Food frequency survey was the most frequent method of dietary assessment, and parent served as proxies for children in all studies. Lower fruit and/or vegetable intake was the most frequently reported dietary outcome, followed by increased energy intake with increased television viewing. The majority of studies reported adverse dietary outcomes with as little as 1 h of daily television exposure. While these results are consistent with recommendations from child health advocates to limit television viewing in young children, they also suggest that further efforts to limit television viewing in young children may be needed to aid in obesity prevention. © 2012 The Authors. obesity reviews © 2012 International Association for the Study of Obesity.

  20. Stakeholder views of superfund sites

    Nearly ten years have passed since the enactment of the federal Comprehensive Response, Compensation, and Liability Act (CERCLA), usually referred to as open-quotes Superfundclose quotes. Nearly four years have passed since CERCLA's major overhaul through the Superfund Amendments and Reauthorization Act (SARA). Although much still remains to be done under Superfund, there is now enough experience to assess how effectively it is working. A study being undertaken by the University of Tennessee's Waste Management Research and Education Institute will supply a portion of that assessment. The study was completed in the fall of 1990. Our study examines two related issues: the resources that will be needed in the coming years to fulfill the mandate of Superfund and other hazardous waste remediation programs, and the site-level experience to date in implementing CERCLA and SARA. This chapter discusses only the open-quotes site-level experienceclose quotes effort, and only its methodological approach. The purpose of the open-quotes site-level experienceclose quotes effort is to explore what counts as a open-quotes successfulclose quotes site in the eyes of different stakeholders in a Superfund cleanup - e.g., the affected community, the potentially responsible parties (PRPs), state and local officials, and the US Environmental Protection Agency (EPA)

    NASA's Mars Exploration Rover Spirit used its navigation camera to take the images combined into this 210-degree view of the rover's surroundings during the 1,861st to 1,863rd Martian days, or sols, of Spirit's surface mission (March 28 to 30, 2009). The center of the scene is toward the south-southwest. East is on the left. West-northwest is on the right. The rover had driven 22.7 meters (74 feet) southwestward on Sol 1861 before beginning to take the frames in this view. The drive brought Spirit past the northwestern corner of Home Plate. In this view, the western edge of Home Plate is on the portion of the horizon farthest to the left. A mound in middle distance near the center of the view is called 'Tsiolkovsky' and is about 40 meters (about 130 feet) from the rover's position. This view is presented as a cylindrical projection with geometric seam correction.

    Despite the prevalence of problematic Internet pornography viewing and the breadth of intervention approaches to potentially address it, no studies to address this problem have been reported to date. An emerging treatment approach, Acceptance and Commitment Therapy (ACT), holds promise as a treatment for Internet pornography viewing because of its focus on processes hypothesized to underlie this maladaptive behavior. In the first experiment on the treatment of problematic Internet pornography viewing, 6 adult males who reported that their Internet pornography viewing was affecting their quality of life were treated in eight 1.5-hour sessions of ACT for problematic pornography viewing. The effects of the intervention were assessed in a multiple-baseline-across-participants design with time viewing pornography as the dependent variable. Treatment resulted in an 85% reduction in viewing at posttreatment with results being maintained at 3-month follow-up (83% reduction). Increases were seen on measures of quality of life, and reductions were seen on measures of OCD and scrupulosity. Weekly measures of ACT-consistent processes showed reductions that corresponded with reductions in viewing. Large reductions were seen on a measure of psychological flexibility, and minor reductions were seen on measures of thought-action fusion and thought control. Overall, results suggest the promise of ACT as a treatment for problematic Internet pornography viewing and the value of future randomized trials of this approach.

    2003-01-01

    High-density film and the high-luminance view-box system are being recommended for mammograms owing to the improved detection of masses. However, this system causes an increase in radiation. Therefore, the purpose of this study was to assess whether the detection of masses would improve using the normal-luminance view box and normal-density film with different types of contrast systems. Low-contrast detection using receiver operating characteristic (ROC) analysis and high-contrast detection using an American College of Radiology (ACR) phantom were evaluated for the following systems: high-density film and high-luminance view box, normal-density film and normal-luminance view box, and normal-density film with wide latitude and normal-luminance view box. The results showed no significant variation in the detectability of the system with high-density film and high-luminance view box and the normal-density film with wide latitude and normal-luminance view box. However, in terms of low-contrast visibility, the system using normal-density film and normal-luminance view box was significantly reduced in comparison with the others. Therefore, the system with normal-density film with wide latitude and the normal-luminance view box is recommended because of reduced radiation dose. (author)

    2016-01-01

    This article is based on a study of 1,389 medical social workers in 108 hospitals across 12 countries, on their views on spirituality and spiritually sensitive interventions in hospital settings. Results of the logistic regression analyses and structural equation models showed that medical social workers from European countries, United States of America, Canada, and Australia, those had undergone spiritual training, and those who had higher self-reported spiritual experiences scale scores were more likely to have the view that spirituality in hospital settings is for facilitating integral healing and wellness of patients and were more likely to prefer spiritual packages of New Age movements as the form of spiritual program, understand spiritual assessment as assessing the patients' spiritual starting point, to then build on further interventions and were likely to attest the understanding of spiritual techniques as mindfulness techniques. Finally they were also likely to understand the spiritual goals of intervention in a holistic way, that is, as that of integral healing, growth of consciousness and promoting overall well-being of patients vis-à-vis only coping and coming to terms with health adversities. Results of the structural equation models also showed covariances between religion, spirituality training, and scores on the self-reported spiritual experiences scale, having thus a set of compounding effects on social workers' views on spiritual interventions in hospitals. The implications of the results for health care social work practice and curriculum are discussed.

  7. Exploring the World using Street View 360 Images

    Bailey, J.

    2016-12-01

    The phrase "A Picture is Worth a Thousand Words" is an idiom of unknown 20th century origin. There is some belief that the modern use of the phrase stems from an article in a 1921 issue of a popular trade journal, that used "One Look is Worth A Thousand Words" to promote the use of images in advertisements on the sides of streetcars. There is a certain irony to this as nearly a century later the camera technologies on "Street View cars" are collecting images that look everywhere at once. However, while it can be to fun drive along the World's streets, it was the development of Street View imaging systems that could be mounted on other modes of transport or capture platforms (Street View Special Collects) that opened the door for these 360 images to become a tool for exploration and storytelling. Using Special Collect imagery captured in "off-road" and extreme locations, scientists are now using Street View images to assess changes to species habitats, show the impact of natural disasters and even perform "armchair" geology. A powerful example is the imagery captured before and after the 2011 earthquake and tsunami that devastated Japan. However, it is use of the immersive nature of 360 images that truly allows them to create wonder and awe, especially when combined with Virtual Reality (VR) viewers. Combined with the Street View App or Google Expeditions, VR provides insight into what it is like to swim with sealions in the Galapagos or climb El Capitan in Yosemite National Park. While these image could never replace experiencing these locations in real-life, they can inspire the viewer to explore and learn more about the many wonders of our planet. https://www.google.com/streetview/https://www.google.com/expeditions/

  9. Language, Thought, and Culture: Views and Arguments

    2009-07-01

    Full Text Available This study follows two aims: one to review some late views on the relations among language, thought, and culture; and the other, to offer a new strategy, in a novel model, based on last achievements in the minimalist approach. Studying views and arguments, three dichotomies are discussed: 1 the views which confirm the relation between culture and language in opposition to the views that deny this; 2 distinguishing the symmetry-procedural view and the transforming views of language; and 3 distinction among the social-communicational, and the biological-genetic motivations of language. The hypothesis for the novel strategy is that considering what the minimalist program has offered, especially from 2000 onwards, it is possible that language affects thought, while coding the and that culture affects language (which is called ethno-grammar . This is in addition to the biological-genetic base. From this point of view, language’s main function is neither to provide communication, nor to express thought, but to connect cognitive and socio-cultural terminals together.

  10. The activity view of inner speech

    Directory of Open Access Journals (Sweden)

    Fernando eMartínez-Manrique

    2015-03-01

    Full Text Available We distinguish two general approaches to inner speech (IS –the ‘format’ and the ‘activity’ views–, and defend the activity view. The format view grounds the utility of IS on features of the representational format of language, and is related to the thesis that the proper function of IS is to make conscious thinking possible. IS appears typically as a product constituted by representations of phonological features. The view also has implications for the idea that passivity phenomena in cognition may be misattributed IS. The activity view sees IS as a speaking activity that does not have a proper function in cognition. It simply inherits the array of functions of outer speech. We argue that it is methodologically advisable to start from this variety of uses, which suggests commonalities between internal and external activities. The format view has several problems; it has to deny unsymbolized thinking; it cannot easily explain how IS makes thoughts available to consciousness, and it cannot explain those uses of IS where its format features apparently play no role. The activity view not only lacks these problems but also has explanatory advantages: construing IS as an activity allows it to be integrally constituted by its content; the view is able to construe unsymbolized thinking as part of a continuum of phenomena that exploit the same mechanisms, and it offers a simple explanation for the variety of uses of IS.

    2013-06-01

    Various studies have been conducted in many countries to determine the perception/awareness about plastic surgery. The present study assessed the views of college students about plastic surgery. A questionnaire consisted of nine questions regarding the basic knowledge about plastic surgery was randomly distributed among college students. The students were given 20 minutes to fill out the forms. A total of 250 male and 250 female college students were randomly included in the study. The mean age of the male students was 21.1 years as compared to 20.7 years of female students. The top five conditions named were related to hair (89.8%) followed by face scars (88%). The most common procedure named by the students was liposuction (88.2%) followed by hair transplantation. 80.2% of the students opted not to be a plastic surgeon if given an opportunity to select the profession. 33.8% of the students had seen some kinds of plastic surgery operation. Only 5.6% of the students (3.4% male and 2.2% female) had seen some kinds of plastic surgery procedure. 68% of male students and 48% of female students wished to have a plastic surgery procedure sometime in their lives. Majority of the students (88%) got the information from the internet. The second most common source was magazines (85.2%). Majority of the students (53.4%) had an idea of an invisible scar as a result of having a plastic surgery procedure. Only 22% thought to have no scar. Late Michael Jackson was at the top of the list of celebrities having a plastic surgery procedure (97.8%) followed by Nawaz Shariff (92.4%). Despite the rapid growth of plastic surgery in the last two decades, a large portion of population remains unaware of the spatiality. It is essential to institute programs to educate healthcare consumers and providers about the plastic surgery.

    Collective view prediction is to judge the opinions of an active web user based on unknown elements by referring to the collective mind of the whole community. Content-based recommendation and collaborative filtering are two mainstream collective view prediction techniques. They generate predictions by analyzing the text features of the target object or the similarity of users' past behaviors. Still, these techniques are vulnerable to the artificially-injected noise data, because they are not able to judge the reliability and credibility of the information sources.

    2012-11-01

    Influences on TV viewing time, which is associated with adverse health outcomes such as obesity and diabetes, need clarification. We assessed the relation of neighborhood socioeconomic status (SES) and walkability with TV viewing time in the Black Women's Health Study, a prospective study of African American women. We created neighborhood SES and walkability scores using data from the U.S. census and other sources. We estimated odds ratios for TV viewing 5+ hours/day compared with 0-1 hours/day for quintiles of neighborhood SES and walkability scores. Neighborhood SES was inversely associated with TV viewing time. The odds ratio for watching 5+ hours/day in the highest compared with the lowest quintile of neighborhood SES was 0.66 (95% CI 0.54-0.81). Neighborhood walkability was not associated with TV viewing time. Neighborhood SES should be considered in devising strategies to combat the high levels of sedentariness prevalent in African American women.

    2016-03-01

    In this paper, a novel L2-SVM based classifier Multi-view L2-SVM is proposed to address multi-view classification tasks. The proposed Multi-view L2-SVM classifier does not have any bias in its objective function and hence has the flexibility like μ-SVC in the sense that the number of the yielded support vectors can be controlled by a pre-specified parameter. The proposed Multi-view L2-SVM classifier can make full use of the coherence and the difference of different views through imposing the consensus among multiple views to improve the overall classification performance. Besides, based on the generalized core vector machine GCVM, the proposed Multi-view L2-SVM classifier is extended into its GCVM version MvCVM which can realize its fast training on large scale multi-view datasets, with its asymptotic linear time complexity with the sample size and its space complexity independent of the sample size. Our experimental results demonstrated the effectiveness of the proposed Multi-view L2-SVM classifier for small scale multi-view datasets and the proposed MvCVM classifier for large scale multi-view datasets.

    2015-04-01

    What do scientists think? That is an important question when engaging in science communication, in which an attempt is made to communicate the scientific understanding to a lay audience. To address this question we undertook a large and detailed survey among scientists studying various aspects of climate change , dubbed "perhaps the most thorough survey of climate scientists ever" by well-known climate scientist and science communicator Gavin Schmidt. Among more than 1800 respondents we found widespread agreement that global warming is predominantly caused by human greenhouse gases. This consensus strengthens with increased expertise, as defined by the number of self-reported articles in the peer-reviewed literature. 90% of respondents with more than 10 climate-related peer-reviewed publications (about half of all respondents), agreed that anthropogenic greenhouse gases are the dominant cause of recent global warming, i.e. having contributed more than half of the observed warming. With this survey we specified what the consensus position entails with much greater specificity than previous studies. The relevance of this consensus for science communication will be discussed. Another important result from our survey is that the main attribution statement in IPCC's fourth assessment report (AR4) may lead to an underestimate of the greenhouse gas contribution to warming, because it implicitly includes the lesser known masking effect of cooling aerosols. This shows the importance of the exact wording in high-profile reports such as those from IPCC in how the statement is perceived, even by fellow scientists. The phrasing was improved in the most recent assessment report (AR5). Respondents who characterized the human influence on climate as insignificant, reported having the most frequent media coverage regarding their views on climate change. This shows that contrarian opinions are amplified in the media in relation to their prevalence in the scientific community. This

  18. View-invariant object recognition ability develops after discrimination, not mere exposure, at several viewing angles.

    Science.gov (United States)

    Yamashita, Wakayo; Wang, Gang; Tanaka, Keiji

    2010-01-01

    One usually fails to recognize an unfamiliar object across changes in viewing angle when it has to be discriminated from similar distractor objects. Previous work has demonstrated that after long-term experience in discriminating among a set of objects seen from the same viewing angle, immediate recognition of the objects across 30-60 degrees changes in viewing angle becomes possible. The capability for view-invariant object recognition should develop during the within-viewing-angle discrimination, which includes two kinds of experience: seeing individual views and discriminating among the objects. The aim of the present study was to determine the relative contribution of each factor to the development of view-invariant object recognition capability. Monkeys were first extensively trained in a task that required view-invariant object recognition (Object task) with several sets of objects. The animals were then exposed to a new set of objects over 26 days in one of two preparatory tasks: one in which each object view was seen individually, and a second that required discrimination among the objects at each of four viewing angles. After the preparatory period, we measured the monkeys' ability to recognize the objects across changes in viewing angle, by introducing the object set to the Object task. Results indicated significant view-invariant recognition after the second but not first preparatory task. These results suggest that discrimination of objects from distractors at each of several viewing angles is required for the development of view-invariant recognition of the objects when the distractors are similar to the objects.

    2011-01-01

    Purpose: To improve the performance of a computer-aided detection (CAD) system for mass detection by using four-view information in screening mammography. Methods: The authors developed a four-view CAD system that emulates radiologists' reading by using the craniocaudal and mediolateral oblique views of the ipsilateral breast to reduce false positives (FPs) and the corresponding views of the contralateral breast to detect asymmetry. The CAD system consists of four major components: (1) Initial detection of breast masses on individual views, (2) information fusion of the ipsilateral views of the breast (referred to as two-view analysis), (3) information fusion of the corresponding views of the contralateral breast (referred to as bilateral analysis), and (4) fusion of the four-view information with a decision tree. The authors collected two data sets for training and testing of the CAD system: A mass set containing 389 patients with 389 biopsy-proven masses and a normal set containing 200 normal subjects. All cases had four-view mammograms. The true locations of the masses on the mammograms were identified by an experienced MQSA radiologist. The authors randomly divided the mass set into two independent sets for cross validation training and testing. The overall test performance was assessed by averaging the free response receiver operating characteristic (FROC) curves of the two test subsets. The FP rates during the FROC analysis were estimated by using the normal set only. The jackknife free-response ROC (JAFROC) method was used to estimate the statistical significance of the difference between the test FROC curves obtained with the single-view and the four-view CAD systems. Results: Using the single-view CAD system, the breast-based test sensitivities were 58% and 77% at the FP rates of 0.5 and 1.0 per image, respectively. With the four-view CAD system, the breast-based test sensitivities were improved to 76% and 87% at the corresponding FP rates, respectively

    Fisher, R. W.

    1983-01-01

    The Variable Acuity Remote Viewing System (VARVS), originally developed under contract to the Navy (ONR) as a laboratory brassboard, was modified for flight demonstration. The VARVS system was originally conceived as a technique which could circumvent the acuity/field of view/bandwidth tradeoffs that exists in remote viewing to provide a nearly eye limited display in both field of view (160 deg) and resolution (2 min arc) while utilizing conventional TV sensing, transmission, and display equipment. The modifications for flight demonstration consisted of modifying the sensor so it could be installed and flow in a Piper PA20 aircraft, equipped for remote control and modifying the display equipment so it could be integrated with the NASA Research RPB (RPRV) remote control cockpit.

    It is important to highlight that attempts at understanding and explaining addiction have been made for centuries. It is, however, just five decades ago, with the growth of science and technology that more interest has been observed in this field. This chapter examines different views and theories that have been posited to understand and explain addiction. More attention will be given to prominent views that seem to draw consensus among researchers and medical practitioners. The first section of the chapter introduces the addiction debate, the different theories that have been provided to explain it from different perspectives and disciplines such as neurosciences, philosophy and psychology. Then, the chapter discusses different views on the role of relapse and what it entails in understanding addiction. The second section discusses different proposed and used forms of treating addiction. Thus, the chapter discusses the received view of addiction, the understanding of relapse as a critical element in addiction and treatments.

    A Data Warehouse contains lots of materialized views over the data provided by the distributed heterogeneous databases for the purpose of efficiently implementing decision-support or OLAP queries. It is important to select the right view to materialize that answer a given set of queries. In this paper, we have addressed and designed algorithm to select a set of views to materialize in order to answer the most queries under the constraint of a given space. The algorithm presented in this paper aim at making out a minimum set of views, by which we can directly respond to as many as possible user"s query requests. We use experiments to demonstrate our approach. The results show that our algorithm works better. We implemented our algorithms and a performance study of the algorithm shows that the proposed algorithm gives a less complexity and higher speeds and feasible expandability.

    Full Text Available ABSTRACTThis study aims at assessing the connection between financial results and non-financial assessments from the consumer’s point of view, considering Brazil’s cellular phone context. According to consumer relationship theory, higher profits are to be expected from satisfied customers, from those who tend towards long-term use of company services. Therefore, non-financial assessments such as satisfaction, commitment, trust and loyalty were correlated to financial results, according to consumption information reported by consumers themselves. Altogether, 493 cases were investigated in a non-probabilistic sample of customers belonging four different mobile phone operators. The relationship quality assessment model was confirmed, although the expected connection between satisfaction, loyalty and financial results was not observed. Results obtained suggest sector-specific assessments, in which mobile phone user behavior is not revealed in a linear way. Findings suggest new perspectives for relationship quality analysis applied to customers within growing markets that harbor a wide range of offers amongst competitors.O presente estudo se propõe a avaliar a relação entre resultado financeiro e avaliação não financeira sob a ótica do consumidor, considerando o contexto de telefonia celular brasileiro. De acordo com a teoria de relacionamento com o consumidor, é esperada maior rentabilidade de clientes satisfeitos e que tenham perspectiva de longo prazo com o uso dos serviços da empresa. Para isso, avaliações não financeiras, como satisfação, comprometimento, confiança e lealdade foram relacionadas com o resultado financeiro de acordo com informações de consumo declaradas por consumidores. Foram pesquisados 493 casos em caráter não probabilístico entre clientes de quatro operadoras de telefonia celular. O modelo de avaliação foi corroborado, embora a relação esperada entre satisfação e lealdade com o retorno financeiro

    Objective To assess the long-term association between childhood television viewing and adult unemployment, and if this association is mediated by educational achievement. Method Study members were a general-population birth cohort of 1037 participants born in New Zealand in 1972/1973. Hours of weekday television viewing were reported at ages 5–15. Since age 18, unemployment was assessed retrospectively using life-history calendars to age 32. Information on educational qualifications was collected at age 32. Results Childhood and adolescent television viewing predicted adult unemployment. This association was significant for male study members only (β=0.20, ptelevision viewing remained a predictor of unemployment after adjusting for this (p=0.0035). By logistic regression, each additional hour of daily television viewing was associated with an increased likelihood of spending at least 6 months in unemployment between ages 18–32 years (OR=1.36, 95%, CI=1.06, 1.76, p=0.0157). Conclusion Childhood and adolescent television viewing may have long-lasting consequences for adult unemployment for boys. This association is only partially explained by the association between television viewing and educational achievement. PMID:22178044

    Full Text Available Objectives. This study aimed to compare changes in ocular status after 3D TV viewing under three modes of illumination and thereby identify optimal illumination for 3D TV viewing. Methods. The following measures of ocular status were assessed: the accommodative response, accommodative microfluctuation, accommodative facility, relative accommodation, gradient accommodative convergence/accommodation (AC/A ratio, phoria, and fusional vergence. The observers watched 3D television for 90 minutes through 3D shutter glasses under three illumination modes: A, complete darkness; B, back illumination (50 lx; and C, front illumination (130 lx. The ocular status of the observers was assessed both before and after the viewing. Results. After 3D TV viewing, the accommodative response and accommodative microfluctuation were significantly changed under illumination Modes A and B. The near positive fusional vergence decreased significantly after the 90-minute 3D viewing session under each illumination mode, and this effect was not significantly different among the three modes. Conclusions. Short-term 3D viewing modified the ocular status of adults. The least amount of such change occurred with front illumination, suggesting that this type of illumination is an appropriate mode for 3D shutter TV viewing.

    Our purpose was to describe a technique for simulating the surgical view of ruptured intracranial aneurysms, using volume-rendering techniques in spiral computed tomography (CT) angiography data. The 3D (three-dimensional) rendered images were assessed by a team consisted of four radiologists, one neurosurgeon and one medical physicist. The resultant 'surgical view' image was standardized in space using a three-dimensional coordinate system, which allowed for its reproduction in the operating theatre. The surgical views are a potentially useful tool for the surgical planning of intracranial aneurysms.

    The original ITER In-Vessel Viewing System (IVVS) prototype (Proc. of the 20th SOFT, vol. 2 (1998) 1051), which demonstrates the feasibility of linear fibre arrays for ITER in-vessel viewing, has been modified. In order to reduce the viewing time and to improve the image quality the beam dispersing mirrors was replaced by a diffractive optics element (DOE), which enhanced the laser illumination considerably. The performance of the system was tested using various target surfaces: the results obtained clearly indicate its adequacy for in-vessel viewing. Mechanical damage on smooth metal surfaces (scratches etc.) can be easily distinguished and the viewing resolution at a distance of 2 m is better than 1 mm. The IVVS has been re-designed to be compatible with the new ITER-FEAT. A conceptual study which covers all the functions and subsystems required for viewing has been completed. These results will be used to further modify the prototype: items to be tested include horizontal probe operation and laser illumination with an optical fibre

    View factors are essential components for analysis for of radiative heat transfer through enclosure methods like radiosity approach, direct/total exchange area approach etc. View factor is defined as the integral over the interacting surface. View factor integral can be calculated by following various approaches, such as: view factor algebra, direction analytical approach, contour integration method, Monte Carlo method, numerical methods based of FDM or FEM, Hottle's string method etc. The present module of work on determination of view factor is aimed for use in ASTEC code system for severe accident analysis. There exist many routines (RADB, RADC, GRADEB, RADR, RADL) in the ICARE module of ASTEC code system to model radiative heat transfer from different types of assemblies of interacting surfaces of different nature. The present work is specially targeted for radiative heat transfer model for lower plenum (RADILOWE) and for extension of ICARE module for IPHWR. In interacting surfaces within the lower plenum comprises of different types of circular, cylindrical and conical surface. In the work completed so far, view factor relations have been derived/compiled based on exact/approximate analytical and numerical approaches. (author)

  20. TFTR vertically viewing electron cyclotron emission diagnostic

    Taylor, G.

    1990-01-01

    The Tokamak Fusion Test Reactor (TFTR) Michelson interferometer has a spectral coverage of 75--540 GHz, allowing measurement of the first four electron cyclotron harmonics. Until recently the instrument has been configured to view the TFTR plasma on the horizontal midplane, primarily in order to measure the electron temperature profile. Electron cyclotron emission (ECE) extraordinary mode spectra from TFTR Supershot plasmas exhibit a pronounced, spectrally narrow feature below the second harmonic. A similar feature is seen with the ECE radiometer diagnostic below the electron cyclotron fundamental frequency in the ordinary mode. Analysis of the ECE spectra indicates the possibility of a non-Maxwellian 40--80 keV tail on the electron distribution in or near the core. During 1990 three vertical views with silicon carbide viewing targets will be installed to provide a direct measurement of the electron energy distribution at major radii of 2.54, 2.78, and 3.09 m with an energy resolution of approximately 20% at 100 keV. To provide the maximum flexibility, the optical components for the vertical views will be remotely controlled to allow the Michelson interferometer to be reconfigured to either the midplane horizontal view or one of the three vertical views between plasma shots

    Since the beginning of 2009, due to the CERN restructuring, LabVIEW support moved from the IT to the EN department, joining the Industrial Controls and Electronics Group (ICE). LabVIEW support has been merged with the Measurement, Test and Analysis (MTA) section which, using LabVIEW, has developed most of the measurement systems to qualify the LHC magnets and components over the past 10 years. The post mortem analysis for the LHC hardware commissioning has also been fully implemented using LabVIEW, customised into a framework, called RADE, for CERN needs. The MTA section has started with a proactive approach sharing its tools and experience with the CERN LabVIEW community. Its framework (RADE) for CERN integrated application development has been made available to the users. Courses on RADE have been integrated into the standard National Instruments training program at CERN. RADE and LabVIEW support were merged together in 2010 on a single email address:labview.support@cern.ch For more information please...

  2. Semi-Supervised Multi-View Ensemble Learning Based On Extracting Cross-View Correlation

    2016-05-01

    Full Text Available Correlated information between different views incorporate useful for learning in multi view data. Canonical correlation analysis (CCA plays important role to extract these information. However, CCA only extracts the correlated information between paired data and cannot preserve correlated information between within-class samples. In this paper, we propose a two-view semi-supervised learning method called semi-supervised random correlation ensemble base on spectral clustering (SS_RCE. SS_RCE uses a multi-view method based on spectral clustering which takes advantage of discriminative information in multiple views to estimate labeling information of unlabeled samples. In order to enhance discriminative power of CCA features, we incorporate the labeling information of both unlabeled and labeled samples into CCA. Then, we use random correlation between within-class samples from cross view to extract diverse correlated features for training component classifiers. Furthermore, we extend a general model namely SSMV_RCE to construct ensemble method to tackle semi-supervised learning in the presence of multiple views. Finally, we compare the proposed methods with existing multi-view feature extraction methods using multi-view semi-supervised ensembles. Experimental results on various multi-view data sets are presented to demonstrate the effectiveness of the proposed methods.

    Background and purpose . Research in nature of science (NOS) among Asia-Pacific countries such as Singapore is arguably scarce. This study aimed to survey Singaporean secondary school students' views of NOS with a newly developed instrument named Students' Views of Nature of Science (SVNOS), which included various key aspects of NOS that are generally agreed upon by the science education community. Moreover, the relations between some demographic factors, including gender and grade, and students' views of NOS were explored. Sample, design and method In total, 359 Singaporean seventh and eighth graders were invited to participate in this survey. The reliability, validity and structure of the SVNOS instrument were ensured by confirmatory factor analysis. A two-way multivariate analysis of variance was then conducted to determine the interaction effects between the gender variable and the grade-level variable. Results and conclusion The results indicated that the SVNOS instrument is reliable and valid to assess students' views of NOS regarding seven distinct NOS dimensions. The male students were more prone to have constructivist-oriented views of NOS in the most of the SVNOS dimensions, while the female students conveyed more non-objective views of NOS. In addition, the eighth graders revealed more empiricist-oriented views of NOS than the seventh graders in several SVNOS dimensions. This result seems to contradict the results of previous studies that students' views of NOS may reflect a developmental trend with their increasing educational experiences.

    Every accelerator has a control system; at present the SPS has two, both of which are needed to run the machine. Consequently a user of the SPS/LEP complex has to be concurrently familiar with three control systems. While this situation brings problems it allows, even forces, comparison between the different systems, which in turn enriches the user viewpoint. This paper assesses the SPS and LEP control systems from the point of view of the user, who may be an equipment specialist, operator, accelerator physicist or combinations thereof. (author)

    The goal was to quantify television viewing in day care settings and to investigate the characteristics of programs that predict viewing. A telephone survey of licensed child care programs in Michigan, Washington, Florida, and Massachusetts was performed. The frequency and quantity of television viewing for infants, toddlers, and preschool-aged children were assessed. With the exception of infants, children in home-based child care programs were exposed to significantly more television on an average day than were children in center-based programs (infants: 0.2 vs 0 hours; toddlers: 1.6 vs 0.1 hours; preschool-aged children: 2.4 vs 0.4 hours). In a regression analysis of daily television time for preschool-aged children in child care, center-based programs were found to have an average of 1.84 fewer hours of television each day, controlling for the other covariates. Significant effect modification was found, in that the impact of home-based versus center-based child care programs differed somewhat depending on educational levels for staff members; having a 2- or 4-year college degree was associated with 1.41 fewer hours of television per day in home-based programs, but no impact of staff education on television use was observed in center-based programs. For many children, previous estimates of screen time significantly underestimated actual amounts. Pediatricians should council parents to minimize screen time in child care settings.

    This study is to examine how viewing a Japanese garden affects Japanese patients with dementia. In a previous study, authors explored the effect on individuals with Alzheimer's disease of viewing an indoor Japanese garden at a nursing home in the United States and reported that viewing the garden significantly reduced the heart rate, evoked short-term and long-term memories, and improved behavioral symptoms. However, it was unclear whether these effects were caused by the design of Japanese garden or unfamiliarity of the design to Caucasians. We constructed a Japanese garden on the rooftop of a hospital in Japan and assessed with a total of 25 subjects on the following categories: (1) eye movement, (2) heart rate, and (3) behavior under four different conditions: (a) open view of the site before construction of the Japanese garden (the control space), (b) open view of the Japanese garden, (c) view of the Japanese garden through closed door, and (d) view of Japanese garden through closed door with the chrysanthemum scent. Findings/Results: Viewers' eyes scanned larger area while viewing the Japanese garden, and viewing the Japanese garden significantly reduced heart rate and improved behavioral symptoms than the control space. We also found that the effect of viewing the same Japanese garden differed across three conditions: the view through an open door, a closed door, and a closed door with added scent.

    2015-01-01

    The negative consequences of peer-victimization on children and adolescents are major public health concerns which have been subjected to extensive research. Given all efforts made to analyze and estimate the social and health consequences of peer-victimization, the adolescents' own experiences and understandings have had surprisingly little impact on the definition of bullying. Therefore, the aim of the current study is to explore adolescents' definitions of bullying. A questionnaire study (n = 128) and four focus group interviews (n = 21) were conducted among students aged 13 and 15. First, gender and age differences were analyzed with respect to what behaviors are considered bullying (questionnaire data). Second, analysis of what bullying is (focus group interviews) was conducted using qualitative content analysis. The adolescents own understanding and definition of bullying didn't just include the traditional criteria of repetition and power imbalance, but also a criterion based on the health consequences of bullying. The results showed that a single but hurtful or harmful incident also could be considered bullying irrespective of whether the traditional criteria were fulfilled or not. Further, girls and older students had a more inclusive view of bullying and reported more types of behaviors as bullying compared to boys and younger students. The results of the current study adds to the existing literature by showing that adolescents consider the victim's experience of hurt and harm as a criterion for defining bullying and not only as consequences of bullying. This may be of special relevance for the identification and classification of bullying incidents on the internet where devastating consequences have been reported from single incidents and the use of the traditional criteria of intent, repetition and power imbalance may not be as relevant as for traditional bullying. It implies that the traditional criteria included in most definitions of bullying

    Full Text Available Sedentary behavior such as television viewing may be an independent risk factor for coronary heart disease. However, few studies have assessed the impact of television viewing time on coronary artery calcification and it remains unclear how body fat contributes to this relationship. The aim of this study is to evaluate the association between television viewing time and subclinical atherosclerosis and whether effects on visceral or subcutaneous fat may mediate any associations observed.This was a cross-sectional study of 398 Chinese participants (192 men and 206 women from Singapore prospective study. Participants were free from known cardiovascular diseases and underwent interview, health screening, computed tomography scans of coronary arteries and abdomen. Spearman's correlation was used to test the correlation between television viewing time, physical activity, body composition and abdominal fat distribution. The association between television viewing time and subclinical atherosclerosis was assessed by multiple logistic regression analysis.In men, television viewing time was significantly correlated with higher body fat mass index, percent body fat, subcutaneous and visceral fat. These associations were in the same direction, but weaker and not statistically significant in women. Television viewing time (hours/day was associated with subclinical atherosclerosis in men (odds ratio: 1.41, 95% CI: 1.03-1.93 but no significant association was observed in women (odds ratio: 0.88, 95% CI: 0.59-1.31 after adjusting for potential socio-demographic and lifestyle confounders. Further adjustments for biological factors did not affect these associations.Television viewing time was associated with greater adiposity and higher subcutaneous and visceral fat in men. TV viewing time was also associated with subclinical atherosclerosis in men and the potential mechanisms underlying this association require further investigation.

  13. View Estimation Based on Value System

    Science.gov (United States)

    Takahashi, Yasutake; Shimada, Kouki; Asada, Minoru

    Estimation of a caregiver's view is one of the most important capabilities for a child to understand the behavior demonstrated by the caregiver, that is, to infer the intention of behavior and/or to learn the observed behavior efficiently. We hypothesize that the child develops this ability in the same way as behavior learning motivated by an intrinsic reward, that is, he/she updates the model of the estimated view of his/her own during the behavior imitated from the observation of the behavior demonstrated by the caregiver based on minimizing the estimation error of the reward during the behavior. From this view, this paper shows a method for acquiring such a capability based on a value system from which values can be obtained by reinforcement learning. The parameters of the view estimation are updated based on the temporal difference error (hereafter TD error: estimation error of the state value), analogous to the way such that the parameters of the state value of the behavior are updated based on the TD error. Experiments with simple humanoid robots show the validity of the method, and the developmental process parallel to young children's estimation of its own view during the imitation of the observed behavior of the caregiver is discussed.

    The Actual Nature Systems (ANS) continually are under spatial-temporal governing external influences from other systems (Meteorology and Geophysics). This influences provide own spatial temporal patterns on the Earth Nature Systems, which reforms these influences by own manner and scales. These at last three systems belong to the Open Non Equilibrium Nature Systems (ONES). The Geophysics and Meteorology Systems are both governing for the ANS on the Earth. They provide as continual energetic pressure and impacts, and direct Extremes from the both systems to the ANS on Earth surface (earthquakes, storms, and others). The Geodynamics of the ANS is under mixing of influence for both systems, on their scales and on dynamics of their spatial-temporal structures, and by own ANS properties, as the ONES. To select influences of external systems on the Earth systems always is among major tasks of the Geomorphology. Mixing of the Systems scales and dynamics provide specific properties for the memory of Earth system. The memory of the ANS has practical value for their multi-purpose management. The knowledge of these properties is the key for research spatial-temporal GeoDynamics and Trends of Earth Nature Systems. Selection of the influences in time and space requires for special tool, requires elaboration and action of the Virtual Nature Systems (VNS), which are enliven computer doubles for analysis Geodynamics of the ANS. The Experience on the VNS enables to assess influence of each and both external factors on the ANS. It is source of knowledge for regional tectonic and climate oscillations, trends, and threats. Research by the VNS for spatial-temporal dynamics and structures of stochastic regimes of governing systems and processes results in stochastic GeoDynamics of environmental processes, in forming of false trends and blanks in natural records. This ‘wild dance' of 2D stochastic patterns and their interaction each other and generates acting structures of river nets

The rapid growth in technical, economical, and social aspects has encouraged 3D TV manufacturers to apply 3D rendering technology to mobile devices so that people have more opportunities to come into contact with many 3D content anytime and anywhere. Even if the mobile 3D technology leads to the current market growth, there is an important thing to consider for consistent development and growth in the display market. To put it briefly, human factors linked to mobile 3D viewing should be taken into consideration before developing mobile 3D technology. Many studies have investigated whether mobile 3D viewing causes undesirable biomedical effects such as motion sickness and visual fatigue, but few have examined main factors adversely affecting human health. Viewing distance is considered one of the main factors to establish optimized viewing environments from a viewer's point of view. Thus, in an effort to determine human-friendly viewing environments, this study aims to investigate the effect of viewing distance on human visual system when exposing to mobile 3D environments. Recording and analyzing brainwaves before and after watching mobile 3D content, we explore how viewing distance affects viewing experience from physiological and psychological perspectives. Results obtained in this study are expected to provide viewing guidelines for viewers, help ensure viewers against undesirable 3D effects, and lead to make gradual progress towards a human-friendly mobile 3D viewing.

    Cultivation theory and research has been criticized for its failure to consider variation in effects by genre, employ appropriate third-variable controls, and determine causal direction. Recent studies, controlling for a variety of demographic characteristics and media use variables, have found that exposure to local television (TV) newscasts is associated with a variety of problematic "real-world" beliefs. However, many of these studies have not adequately assessed causal direction. Redressing this limitation, we analyzed data from a two-wave national representative survey which permitted tests of lagged association between overall TV viewing, local TV news viewing, and fatalistic beliefs about cancer prevention. We first replicated the original cultivation effect and found a positive association between overall TV viewing at time 1 and increased fatalistic beliefs about cancer prevention at time 2. Analyses also provided evidence that local TV news viewing at time 1 predicts increased fatalistic beliefs about cancer prevention at time 2. There was little evidence for reverse causation in predicting changes in overall TV viewing or local TV news viewing. The paper concludes with a discussion of theoretical and practical implications of these findings.

    A 3-dimensional echocardiographic view of the mitral valve, called the "en face" or "surgical view," presents a view of the mitral valve similar to that seen by the surgeon from a left atrial perspective. Although the anatomical landmarks of this view are well defined, no comprehensive echocardiographic definition has been presented. After reviewing the literature, we provide a definition of the left atrial and left ventricular en face views of the mitral valve. Techniques used to acquire this view are also discussed.

    In-vessel viewing systems are essential to inspect all surface of in-vessel components so as to detect and locate damages, and to assist in-vessel maintenance operations. The in-vessel viewing operations are categorized into the three cases, which are 1) rapid inspection just after off-normal events such as disruption, 2) scheduled inspection, and 3) supplementary inspection during maintenance operations. In case of the rapid inspection, the viewing systems have to be operated in vacuum (ca. 10 -5 Pa) and high temperature (ca. 300degC) under a gamma ray dose rate of 10 7 R/h. On the other hand, the latter two cases are anticipated to be under atmospheric inert gas, 150degC and 3x10 6 R/h. Accordingly, the in-vessel viewing systems are required to have sufficient durability under those conditions of all cases as well as precision of the vision to all of in-vessel surface. Based on those requirements, scoping studies on various viewing concepts have been performed and the applicability to the ITER conditions have been assessed. As a result, two types of viewing systems have been chosen, which are a periscope type viewing system and a image fiber type viewing system with a multi-joint manipulator. Both systems are based on radiation hard optical elements which are being developed. In this report, the design features of both viewing systems are described, including technical issues for ITER application. Finally, a periscope type viewing system is recommended as a primary system and the following specifications/conditions are proposed for the further engineering design. (1) Unified type periscope with a movable mirror at the tip (2) Integrated lighting device into the periscope (3) Accessed from top vertical ports located at 7.3m from the machine center (4) Proposed configuration with a total length of around 27m and a diameter of 200mm.

    Full Text Available Objectives: This study aimed to assess the prevalence of prolonged television, computer, and mobile phone viewing times and examined related sociodemographic factors among Chinese pregnant women. Methods: In this study, a cross-sectional survey was implemented among 2400 Chinese pregnant women in 16 hospitals of 5 provinces from June to August in 2015, and the response rate of 97.76%. We excluded women with serious complications and cognitive disorders. The women were asked about their television, computer, and mobile phone viewing during pregnancy. Prolonged television watching or computer viewing was defined as spending more than two hours on television or computer viewing per day. Prolonged mobile phone viewing was watching more than one hour on mobile phone per day. Results: Among 2345 pregnant women, about 25.1% reported prolonged television viewing, 20.6% reported prolonged computer viewing, and 62.6% reported prolonged mobile phone viewing. Pregnant women with long mobile phone viewing times were likely have long TV (Estimate = 0.080, Standard Error (SE = 0.016, p < 0.001 and computer viewing times (Estimate = 0.053, SE = 0.022, p = 0.015.

    In debates on euthanasia legalization in Belgium, the voices of nurses were scarcely heard. Yet studies have shown that nurses are involved in the caring process surrounding euthanasia. Consequently, they are in a position to offer valuable ideas about this problem. For this reason, the views of these nurses are important because of their palliative expertise and their daily confrontation with dying patients. The aim of this paper is to report a study of the views of palliative care nurses about euthanasia. A grounded theory approach was chosen, and interviews were carried out with a convenience sample of 12 palliative care nurses in Flanders (Belgium). The data were collected between December 2001 and April 2002. The majority of the nurses were not a priori for or against euthanasia, and their views were largely dependent on the situation. What counted was the degree of suffering and available palliative options. Depending on the situation, we noted both resistance and acceptance towards euthanasia. The underlying arguments for resistance included respect for life and belief in the capabilities of palliative care; arguments underlying acceptance included the quality of life and respect for patient autonomy. The nurses commented that working in palliative care had a considerable influence on one's opinion about euthanasia. In light of the worldwide debate on euthanasia, it is essential to know how nurses, who are confronted with terminally ill patients every day, think about it. Knowledge of these views can also contribute to a realistic and qualified view on euthanasia itself. This can be enlightening to the personal views of caregivers working in a diverse range of care settings.

    The dental program at the Malmö Dental School, the so called Malmö-model, is guided by four linked principles: self-directed learning, teamwork, a holistic view of patient care, and oral health (Fig.1). Self-assessment ability is a critical competence for healthcare professionals, necessary for the successful adaptation to the modern life-long learning environment. Educational research seems to point out two critical factors for the development of such skills, continuous practice of self-assessment and constructive feedback. The first study presented in this thesis assessed students' self-assessment ability by means of the Interactive Examination in a cohort of senior dental students, who had gone through an identical assessment procedure during their second year of studies. The results indicated that self-assessment ability was not directly relevant to subject knowledge. Upon graduation, there were a number of students (10%) with significant self-assessment difficulties. Early detection of students with weak self-assessment abilities appears possible to achieve. The aim of the second study, concerning teamwork and holistic view, was to investigate if highlighting teamwork between dental and dental hygienist students could improve the students' holistic view on patients, as well as their knowledge of, and insight into, each other's future professions. This project showed that by initiating teamwork between dental and dental hygienist students, it was possible to increase students' knowledge on dental hygienists competence, develop students' perceived holistic view on patients, and prepare students for teamwork. The third study explored findings clinicians used when diagnosing chronic periodontitis. A questionnaire was distributed to students, dental teachers and clinical supervisors in the Public Dental Services. Within all categories of clinicians, the majority of the clinicians used deepened pocket, bone loss on x-rays, and bleeding as findings. There were

    Report describes theoretical and experimental studies of perception of depth by human operators through stereoscopic video systems. Purpose of such studies to optimize dual-camera configurations used to view workspaces of remote manipulators at distances of 1 to 3 m from cameras. According to analysis, static stereoscopic depth distortion decreased, without decreasing stereoscopitc depth resolution, by increasing camera-to-object and intercamera distances and camera focal length. Further predicts dynamic stereoscopic depth distortion reduced by rotating cameras around center of circle passing through point of convergence of viewing axes and first nodal points of two camera lenses.

  9. Collective Attitudes and the Anthropocentric View

    2016-03-01

    Full Text Available The anthropocentric view holds that the social world is a projection of mental states and attitudes onto the real world. However, there is more to a society of individuals than their psychological make up. In The Ant Trap, Epstein hints at the possibility that collective intentionality can, and should, be discarded as a pillar of social ontology. In this commentary I argue that this claim is motivated by an outdated view of the nature and structure of collective attitudes. If we aim at a good theory of social ontology, we need a good theory of collective intentionality.

    Marx's view on labour is many-sided. I will argue the multiple character of labour in five aspects, based on his 1857-58 note. We can grasp his view in following five phases. Namely, (1) material metabolism between man and Nature, (2) abstract human labour, (3) labour and free time, (4) active and creative labour, and (5) painful labour. In general, Marx's statements on (3), (4) and (5) phases of labour are less in his "Capital" than in his 1857-58 note. This is the reason why we often deal w...

    1979-01-01

    A collimator comprises a block or blocks of radiation-impervious material which defines a first plurality of parallel channels, each channel defining a direction of acceptance of radiation from a body. The axes of a second plurality channels define another direction of acceptance of radiation from the body and intersect the same portion of the body as the axes of the first plurality of channels thus producing a second view of the body. Where the collimator is built up as a stack of blocks, each pair of adjacent blocks defines a slice of the body which is viewed from two angles defined by the channels. (UK)

    Full Text Available Objectives: Increasingly people are using the internet to find information about medical and educational issues and one of the simplest ways to obtain information is internet. Persian Cued Speech is a very new system to Iranian families with deaf child and the professionals and a few educators have enough knowledge about it, so the purpose of this study was to introduce Persian Cued Speech website to deaf educators and rehabilitation professionals and assess their views about the website and their accessibility to important information through its use. Methods:The sample group was randomly selected fromdeaf educators and rehabilitation professionals working in different educational settings for deaf children in Tehran, our capital .They completed a questionnaire which was adopted from different website assessing questionnaires. Researchers also completed an interview with the sample group. Results: Our findings show that from the deaf educators and rehabilitation professionals point of view,the Persian Cued Speech website was a helpful and informing website. They also wanted more pictures and videos,bigger font sizes and more practical parts.So we decide to change some parts of the website to be more usable for them. Discussion: Using informational websites can be a very helpful tool in the internet area. Helpful websites are those which are more accessible, readable and appropriately designed and are user-friendly.

    2006-05-01

    This paper reports research about upper secondary school pupils' views about science investigations in school. Although researchers, teachers and examiners have expressed opinions about investigative work in science, there have been relatively few studies of pupils' experiences. The present study identified pupils' concerns about the limited time available, timing of the investigations, lack of familiarity with apparatus and the association of investigation almost exclusively with assessment, all factors which contributed to stress. One exceptional school apart, pupils perceived the teacher's role as a didactic supporter of strategies to maximise performance for assessment. We discuss these views and examine the potential for putting policy into practice.

    To determine whether two-view shear-wave elastography (SWE) improves the performance of radiologists in differentiating benign from malignant breast masses compared with single-view SWE. This prospective study was conducted with institutional review board approval, and written informed consent was obtained. B-mode ultrasonographic (US) and orthogonal SWE images were obtained for 219 breast masses (136 benign and 83 malignant; mean size, 14.8 mm) in 219 consecutive women (mean age, 47.9 years; range, 20-78 years). Five blinded radiologists independently assessed the likelihood of malignancy for three data sets: B-mode US alone, B-mode US and single-view SWE, and B-mode US and two-view SWE. Interobserver agreement regarding Breast Imaging Reporting and Data System (BI-RADS) category and the area under the receiver operating characteristic curve (AUC) of each data set were compared. Interobserver agreement was moderate (κ = 0.560 ± 0.015 [standard error of the mean]) for BI-RADS category assessment with B-mode US alone. When SWE was added to B-mode US, five readers showed substantial interobserver agreement (κ = 0.629 ± 0.017 for single-view SWE; κ = 0.651 ± 0.014 for two-view SWE). The mean AUC of B-mode US was 0.870 (range, 0.855-0.884). The AUC of B-mode US and two-view SWE (average, 0.928; range, 0.904-0.941) was higher than that of B-mode US and single-view SWE (average, 0.900; range, 0.890-0.920), with statistically significant differences for three readers (P ≤ .003). The performance of radiologists in differentiating benign from malignant breast masses was improved when B-mode US was combined with two-view SWE compared with that when B-mode US was combined with single-view SWE. © RSNA, 2013

    Research among adults has consistently shown that people holding negative self-views prefer negative over positive feedback. The present study tested the hypothesis that this preference is less robust among pre-adolescents, such that it will be mitigated by a preceding positive event. Pre-adolescents (n = 75) holding positive or negative global self-esteem were randomized to a favorable or unfavorable peer evaluation outcome. Next, preferences for positive versus negative feedback were assessed using an unobtrusive behavioral viewing time measure. As expected, results showed that after being faced with the success outcome children holding negative self-views were as likely as their peers holding positive self-views to display a significant preference for positive feedback. In contrast, children holding negative self-views displayed a stronger preference for negative feedback after being faced with the unfavorable outcome that matched their pre-existing self-views.

    This study assessed the predictive relationship between View of God beliefs and change in CD4-cell and Viral Load (VL) in HIV positive people over an extended period. A diverse sample of HIVseropositive participants (N = 101) undergoing comprehensive psychological assessment and blood draws over the course of 4 years completed the View of God Inventory with subscales measuring Positive View (benevolent/forgiving) and Negative View of God (harsh/judgmental/punishing). Adjusting for initial disease status, age, gender, ethnicity, education, and antiretroviral medication (at every 6-month visit), a Positive View of God predicted significantly slower disease-progression (better preservation of CD4-cells, better control of VL), whereas a Negative View of God predicted faster disease-progression over 4 years. Effect sizes were greater than those previously demonstrated for psychosocial variables known to predict HIV-disease-progression, such as depression and coping. Results remained significant even after adjusting for church attendance and psychosocial variables (health behaviors, mood, and coping). These results provide good initial evidence that spiritual beliefs may predict health outcomes.

    To examine the prevalence of television (TV) viewing, computer use, and their combination and associations with demographic characteristics and body mass index (BMI) among U.S. youth. The 1999 to 2006 National Health and Nutrition Examination Survey (NHANES) was used. Time spent yesterday sitting and watching television or videos (TV viewing) and using the computer or playing computer games (computer use) were assessed by questionnaire. Prevalence (%) of meeting the U.S. objective for TV viewing (< or =2 hours/day) ranged from 65% to 71%. Prevalence of no computer use (0 hours/day) ranged from 23% to 45%. Non-Hispanic Black youth aged 2 to 15 years were less likely than their non-Hispanic White counterparts to meet the objective for TV viewing. Overweight or obese school-age youth were less likely than their normal weight counterparts to meet the objective for TV viewing. Computer use is prevalent among U.S. youth; more than half of youth used a computer on the previous day. The proportion of youth meeting the U.S. objective for TV viewing is less than the target of 75%. Time spent in sedentary behaviors such as viewing TV may contribute to overweight and obesity among U.S. youth.

    2013-06-04

    A randomized crossover study explored whether viewing different scenes prior to a stressor altered autonomic function during the recovery from the stressor. The two scenes were (a) nature (composed of trees, grass, fields) or (b) built (composed of man-made, urban scenes lacking natural characteristics) environments. Autonomic function was assessed using noninvasive techniques of heart rate variability; in particular, time domain analyses evaluated parasympathetic activity, using root-mean-square of successive differences (RMSSD). During stress, secondary cardiovascular markers (heart rate, systolic and diastolic blood pressure) showed significant increases from baseline which did not differ between the two viewing conditions. Parasympathetic activity, however, was significantly higher in recovery following the stressor in the viewing scenes of nature condition compared to viewing scenes depicting built environments (RMSSD; 50.0 ± 31.3 vs 34.8 ± 14.8 ms). Thus, viewing nature scenes prior to a stressor alters autonomic activity in the recovery period. The secondary aim was to examine autonomic function during viewing of the two scenes. Standard deviation of R-R intervals (SDRR), as change from baseline, during the first 5 min of viewing nature scenes was greater than during built scenes. Overall, this suggests that nature can elicit improvements in the recovery process following a stressor.

    Mammography screening rates among Chinese American women have been reported to be low. This study examines whether and how culture views and language ability influence mammography adherence in this mostly immigrant population. Asymptomatic Chinese American women (n = 466) aged 50 and older, recruited from the Washington, D.C. area, completed a telephone interview. Regular mammography was defined as having two mammograms at age-appropriate recommended intervals. Cultural views were assessed by 30 items, and language ability measured women's ability in reading, writing, speaking, and listening to English. After controlling for risk perception, worry, physician recommendation, family encouragement, and access barriers, women holding a more Chinese/Eastern cultural view were significantly less likely to have had regular mammograms than those having a Western cultural view. English ability was positively associated with mammography adherence. The authors' results imply that culturally sensitive and language-appropriate educational interventions are likely to improve mammography adherence in this population.

    Full Text Available In this study, it is aimed to determine the high school students’ views on blended learning. The study was carried out in biology course for the lesson unit of “Classification of Living Things and Biodiversity” with 47 9th grade students attending Nevzat Ayaz Anatolian High School in the second term of the academic year of 2009-2010. The lessons were taught in a way appropriate to the blended learning model both via the Internet and on face-to-face basis. As the online dimension of the blended learning model, Moodle, a Learning Management System (LMS, was used. The application lasted 10 weeks. The scale of learners’ views on blended learning was applied and interviews were held to determine the views. As a result of the analysis of the scale, it was seen that their views were “highly” positive. The interviews held with the students revealed that the blended learning model provided students with various opportunities such as getting prepared for the lessons, reviewing the lessons as many times as wanted, reaching the subject-related materials without being dependent on time and place, testing oneself and communicating with the teacher and other students out of the school. The interviews also revealed that there were various problems though such as lack of Internet connection at home and problems experienced while playing the videos.

  15. Decoupled Multicamera Sensing for Flexible View Generation

    Directory of Open Access Journals (Sweden)

    Vivek K. Singh

    2016-01-01

    Full Text Available Any sensing paradigm has three important components, namely, the actor, the sensor, and the environment. Traditionally, the sensors have been attached to either the actor or the environment. This restricts the kind of sensing that can be undertaken. We study a newer decoupled sensing paradigm, which separates the sensors from both the actor and the environment and tremendously increases the flexibility with which the scenes can be viewed. For example, instead of showing just one view, “how the environment sees the actor” or “how the actor sees the environment,” a viewer can choose to see either one or both of these views and even choose to see the scene from any desired position in any desired direction. We describe a methodology using mobile autonomous sensors to undertake such decoupled sensing and study the feasible number as well as the placement of such sensors. Also, we describe how the sensors can coordinate their movements around a moving actor so as to continue capturing the required views with minimum overall cost. The practical results obtained demonstrate the viability of the proposed approach.

    Science.gov (United States)

    Brown, Patrick L.; Abell, Sandra K.; Demir, Abdulkadir; Schmidt, Francis J.

    2006-09-01

    The purposes of this study were to (a) gain an understanding of the views of inquiry held by faculty members involved in undergraduate science teaching and (b) describe the challenges, constraints, and opportunities that they perceived in designing and teaching inquiry-based laboratories. Participants included 19 college professors, representing both life and physical science disciplines, from (a) 2-year community college, (b) small, private nonprofit liberal arts college, (c) public master's granting university, and (d) public doctoral/research extensive university. We collected data through semistructured interviews and applied an iterative data analysis process. College science faculty members held a full and open inquiry view, seeing classroom inquiry as time consuming, unstructured, and student directed. They believed that inquiry was more appropriate for upper level science majors than for introductory or nonscience majors. Although faculty members valued inquiry, they perceived limitations of time, class size, student motivation, and student ability. These limitations, coupled with their view of inquiry, constrained them from implementing inquiry-based laboratories. Our proposed inquiry continuum represents a broader view of inquiry that recognizes the interaction between two dimensions of inquiry: (a) the degree of inquiry and (b) the level of student directedness, and provides for a range of inquiry-based classroom activities.

  20. Effects of multiple viewings of an ultraviolet photo on sun protection behaviors.

    Mahler, H I M

    2018-05-02

    To determine whether multiple viewings of one's ultraviolet (UV) facial photo differentially affects subsequent sun protection behaviors relative to a single viewing. Pretest-posttest control group. Southern California college students (N = 151) were randomly assigned to be shown their UV facial photo one time, multiple times over the course of 2 weeks, or not at all. Emotional reactions, perceived susceptibility to skin damage, and sun protection intentions were assessed immediately, and sun protection behaviors were assessed during a surprise telephonic follow-up 1 month later. Immediately after viewing a UV photo of their face, participants reported significantly greater perceived susceptibility to skin damage, greater intentions to engage in future sun protection, and more negative emotions than those who had not seen a UV photo. Moreover, 1 month later, those who had viewed their UV photo were less likely to report having sunbathed and reported significantly greater sun protection than did controls. There were no differences in sun protection behaviors between those who had been shown their UV photo only once during the initial intervention session and those who had been sent their UV photo several times thereafter. However, among those who had been sent their UV photo several times, those who reported having viewed their photo on additional occasions reported significantly greater sun protection behaviors than those who had not. Being randomly assigned to view a UV facial photo multiple times generally neither strengthened nor weakened effects on subsequent sun protection behaviors relative to being shown the photo just once. However, among those who were sent their photo and thus had the option of viewing it more often than they had been assigned to, those who chose to view their photo more frequently also engaged in more sun protection behaviors.
