    Full Text Available A new class of non facet-to-facet random tessellations in three-dimensional space is introduced -- the so-called column tessellations. The spatial construction is based on a stationary planar tessellation; each cell of the spatial tessellation is a prism whose base facet is  congruent to a cell of the planar tessellation. Thus intensities, topological and metric mean values of the spatial tessellation can be calculated from suitably chosen parameters of the planar tessellation.

  4. Rigidly foldable origami gadgets and tessellations. (United States)

    Evans, Thomas A; Lang, Robert J; Magleby, Spencer P; Howell, Larry L


    Rigidly foldable origami allows for motion where all deflection occurs at the crease lines and facilitates the application of origami in materials other than paper. In this paper, we use a recently discovered method for determining rigid foldability to identify existing flat-foldable rigidly foldable tessellations, which are also categorized. We introduce rigidly foldable origami gadgets which may be used to modify existing tessellations or to create new tessellations. Several modified and new rigidly foldable tessellations are presented.

    Determining the masses of new physics particles appearing in decay chains is an important and longstanding problem in high energy phenomenology. Recently it has been shown that these mass measurements can be improved by utilizing the boundary of the allowed region in the fully differentiable phase space in its full dimensionality. Here we show that the practical challenge of identifying this boundary can be solved using techniques based on the geometric properties of the cells resulting from Voronoi tessellations of the relevant data. The robust detection of such phase space boundaries in the data could also be used to corroborate a new physics discovery based on a cut-and-count analysis.

  6. The art and science of hyperbolic tessellations. (United States)

    Van Dusen, B; Taylor, R P


    The visual impact of hyperbolic tessellations has captured artists' imaginations ever since M.C. Escher generated his Circle Limit series in the 1950s. The scaling properties generated by hyperbolic geometry are different to the fractal scaling properties found in nature's scenery. Consequently, prevalent interpretations of Escher's art emphasize the lack of connection with nature's patterns. However, a recent collaboration between the two authors proposed that Escher's motivation for using hyperbolic geometry was as a method to deliberately distort nature's rules. Inspired by this hypothesis, this year's cover artist, Ben Van Dusen, embeds natural fractals such as trees, clouds and lightning into a hyperbolic scaling grid. The resulting interplay of visual structure at multiple size scales suggests that hybridizations of fractal and hyperbolic geometries provide a rich compositional tool for artists.

  8. Restructuring surface tessellation with irregular boundary conditions

    Directory of Open Access Journals (Sweden)

    Tsung-Hsien Wang


    Full Text Available In this paper, the surface tessellation problem is explored, in particular, the task of meshing a surface with the added consideration of incorporating constructible building components. When a surface is tessellated into discrete counterparts, certain unexpected conditions usually occur at the boundary of the surface, in particular, when the surface is being trimmed. For example, irregularly shaped panels form at the trimmed edges. To reduce the number of irregular panels that may form during the tessellation process, this paper presents an algorithmic approach to restructuring the surface tessellation by investigating irregular boundary conditions. The objective of this approach is to provide an alternative way for freeform surface manifestation from a well-structured discrete model of the given surface.

    Yan, Dongming


    We present a novel remeshing algorithm that avoids triangles with small and triangles with large (obtuse) angles. Our solution is based on an extension to Centroidal Voronoi Tesselation (CVT). We augment the original CVT formulation by a penalty term that penalizes short Voronoi edges, while the CVT term helps to avoid small angles. Our results show significant improvements of the remeshing quality over the state of the art.

  10. Water isotope systematics: Improving our palaeoclimate interpretations (United States)

    Jones, M. D.; Dee, S.; Anderson, L.; Baker, A.; Bowen, G.; Noone, D.


    The stable isotopes of oxygen and hydrogen, measured in a variety of archives, are widely used proxies in Quaternary Science. Understanding the processes that control δ18O change have long been a focus of research (e.g. Shackleton and Opdyke, 1973; Talbot, 1990 ; Leng, 2006). Both the dynamics of water isotope cycling and the appropriate interpretation of geological water-isotope proxy time series remain subjects of active research and debate. It is clear that achieving a complete understanding of the isotope systematics for any given archive type, and ideally each individual archive, is vital if these palaeo-data are to be used to their full potential, including comparison with climate model experiments of the past. Combining information from modern monitoring and process studies, climate models, and proxy data is crucial for improving our statistical constraints on reconstructions of past climate variability.As climate models increasingly incorporate stable water isotope physics, this common language should aid quantitative comparisons between proxy data and climate model output. Water-isotope palaeoclimate data provide crucial metrics for validating GCMs, whereas GCMs provide a tool for exploring the climate variability dominating signals in the proxy data. Several of the studies in this set of papers highlight how collaborations between palaeoclimate experimentalists and modelers may serve to expand the usefulness of palaeoclimate data for climate prediction in future work.This collection of papers follows the session on Water Isotope Systematics held at the 2013 AGU Fall Meeting in San Francisco. Papers in that session, the breadth of which are represented here, discussed such issues as; understanding sub-GNIP scale (Global Network for Isotopes in Precipitation, (IAEA/WMO, 2006)) variability in isotopes in precipitation from different regions, detailed examination of the transfer of isotope signals from precipitation to geological archives, and the

In the present paper this model is reviewed and new results for the mean values of essential geometric features of STIT tessellations in two and three dimensions are provided and proved. For the isotropic model, these mean values are compared with those ones of the Poisson-Voronoi and of the Poisson plane tessellations, respectively.

    Ju, Lili [University of South Carolina; Ringler, Todd [Los Alamos National Laboratory; Gunzburger, Max [Florida State University


    We review the use of Voronoi tessellations for grid generation, especially on the whole sphere or in regions on the sphere. Voronoi tessellations and the corresponding Delaunay tessellations in regions and surfaces on Euclidean space are defined and properties they possess that make them well-suited for grid generation purposes are discussed, as are algorithms for their construction. This is followed by a more detailed look at one very special type of Voronoi tessellation, the centroidal Voronoi tessellation (CVT). After defining them, discussing some of their properties, and presenting algorithms for their construction, we illustrate the use of CVTs for producing both quasi-uniform and variable resolution meshes in the plane and on the sphere. Finally, we briefly discuss the computational solution of model equations based on CVTs on the sphere.

  14. Improving the effectiveness of interpreted consultations: Australian interpreter, general practitioner and patient perspectives. (United States)

    Sturman, Nancy; Farley, Rebecca; Claudio, Fernanda; Avila, Patricia


    Healthcare consultations with patients lacking English proficiency are challenging for all parties, even in Australian primary care where the engagement of interpreters is encouraged and fully subsidised. Our objective was to understand these challenges from the perspectives of interpreters, patients and general practitioners in order to improve the effectiveness of interpreted consultations. Our investigator team approached the interpreted consultation as an interprofessional collaboration. A convenience sample of seven general practitioners, eight health interpreters and six representatives from culturally and linguistically diverse communities (representing the patient perspective) participated in three separate focus group discussions, lasting 60-90 min each, exploring participant experiences with healthcare consultations in which interpreters were present. Two semistructured interviews were undertaken subsequently with three additional community representatives purposively recruited to increase participant diversity. Data were collected in 2016 and analysed inductively using a method of constant comparison to identify, and reach consensus on, key emerging themes. All participant groups emphasised the importance of working with trained interpreters, rather than relying on family interpreters or a doctor's own second language skills. Although participants reported experiences of effective interpreted consultations, other reports suggested that some doctors are unaware of, or have difficulty following, accepted guidelines about speech, gaze and turn-taking. Challenges identified in relation to interpreted consultations fell into the five themes of contextual constraints, consultation complexity, communication difficulties, the interpreter role and collaboration. Some general practitioner participants appeared to be unsure and anxious about the etiquette of interpreted consultations, and there was some confusion between and within participant groups about

  15. The review on tessellation origami inspired folded structure (United States)

    Chu, Chai Chen; Keong, Choong Kok


    Existence of folds enhances the load carrying capacity of a folded structure which makes it suitable to be used for application where large open space is required such as large span roof structures and façade. Folded structure is closely related to origami especially the tessellation origami. Tessellation origami provides a folded configuration with facetted surface as a result from repeated folding pattern. Besides that, tessellation origami has flexible folding mechanism that produced a variety of 3-dimensional folded configurations. Despite the direct relationship between fold in origami and folded structure, the idea of origami inspired folded structure is not properly reviewed in the relevant engineering field. Hence, this paper aims to present the current studies from related discipline which has direct relation with application of tessellation origami in folded structure. First, tessellation origami is properly introduced and defined. Then, the review covers the topic on the origami tessellation design suitable for folded structure, its modeling and simulation method, and existing studies and applications of origami as folded structure is presented. The paper also includes the discussion on the current issues related to each topic.

    Full Text Available This paper presents a Synthetic Aperture Radar (SAR image segmentation approach with unknown number of classes, which is based on regular tessellation and Reversible Jump Markov Chain Monte Carlo (RJMCMC' algorithm. First of all, an image domain is portioned into a set of blocks by regular tessellation. The image is modeled on the assumption that intensities of its pixels in each homogeneous region satisfy an identical and independent Gamma distribution. By Bayesian paradigm, the posterior distribution is obtained to build the region-based image segmentation model. Then, a RJMCMC algorithm is designed to simulate from the segmentation model to determine the number of homogeneous regions and segment the image. In order to further improve the segmentation accuracy, a refined operation is performed. To illustrate the feasibility and effectiveness of the proposed approach, two real SAR image is tested.

  17. Multi-Resolution Seismic Tomography Based on Recursive Tessellation Hierarchy

    Energy Technology Data Exchange (ETDEWEB)

    Simmons, N A; Myers, S C; Ramirez, A


    A 3-D global tomographic model that reconstructs velocity structure at multiple scales and incorporates laterally variable seismic discontinuities is currently being developed. The model parameterization is node-based where nodes are placed along vertices defined by triangular tessellations of a spheroidal surface. The triangular tessellation framework is hierarchical. Starting with a tetrahexahedron representing the whole globe (1st level of the hierarchy, 24 faces), they divide each triangle of the tessellation into daughter triangles. The collection of all daughter triangles comprises the 2nd level of the tessellation hierarchy and further recursion produces an arbitrary number of tessellation levels and arbitrarily fine node-spacing. They have developed an inversion procedure that takes advantage of the recursive properties of the tessellation hierarchies by progressively solving for shorter wavelength heterogeneities. In this procedure, we first perform the tomographic inversion using a tessellation level with coarse node spacing. They find that a coarse node spacing of approximately 8{sup o} is adequate to capture bulk regional properties. They then conduct the tomographic inversion on a 4{sup o} tessellation level using the residuals and inversion results from the 8{sup o} run. In practice they find that the progressive tomography approach is robust, providing an intrinsic regularization for inversion stability and avoids the issue of predefining resolution levels. Further, determining average regional properties with coarser tessellation levels enables long-wavelength heterogeneities to account for sparsely sampled regions (or regions of the mantle where longer wavelength patterns of heterogeneity suffice) while allowing shorter length-scale heterogeneities to emerge where necessary. They demonstrate the inversion approach with a set of synthetic test cases that mimic the complex nature of data arrangements (mixed-determined inversion) common to most

    We present a detailed description of the Voronoi Tessellation (VT) cluster finder algorithm in 2+1 dimensions, which improves on past implementations of this technique. The need for cluster finder algorithms able to produce reliable cluster catalogs up to redshift 1 or beyond and down to 10{sup 13.5} solar masses is paramount especially in light of upcoming surveys aiming at cosmological constraints from galaxy cluster number counts. We build the VT in photometric redshift shells and use the two-point correlation function of the galaxies in the field to both determine the density threshold for detection of cluster candidates and to establish their significance. This allows us to detect clusters in a self-consistent way without any assumptions about their astrophysical properties. We apply the VT to mock catalogs which extend to redshift 1.4 reproducing the ?CDM cosmology and the clustering properties observed in the Sloan Digital Sky Survey data. An objective estimate of the cluster selection function in terms of the completeness and purity as a function of mass and redshift is as important as having a reliable cluster finder. We measure these quantities by matching the VT cluster catalog with the mock truth table. We show that the VT can produce a cluster catalog with completeness and purity >80% for the redshift range up to {approx}1 and mass range down to {approx}10{sup 13.5} solar masses.

  20. Improved interpretation of satellite altimeter data using genetic algorithms (United States)

    Messa, Kenneth; Lybanon, Matthew


    Genetic algorithms (GA) are optimization techniques that are based on the mechanics of evolution and natural selection. They take advantage of the power of cumulative selection, in which successive incremental improvements in a solution structure become the basis for continued development. A GA is an iterative procedure that maintains a 'population' of 'organisms' (candidate solutions). Through successive 'generations' (iterations) the population as a whole improves in simulation of Darwin's 'survival of the fittest'. GA's have been shown to be successful where noise significantly reduces the ability of other search techniques to work effectively. Satellite altimetry provides useful information about oceanographic phenomena. It provides rapid global coverage of the oceans and is not as severely hampered by cloud cover as infrared imagery. Despite these and other benefits, several factors lead to significant difficulty in interpretation. The GA approach to the improved interpretation of satellite data involves the representation of the ocean surface model as a string of parameters or coefficients from the model. The GA searches in parallel, a population of such representations (organisms) to obtain the individual that is best suited to 'survive', that is, the fittest as measured with respect to some 'fitness' function. The fittest organism is the one that best represents the ocean surface model with respect to the altimeter data.

  1. Improving hospital decision making with interpretable associations over datacubes. (United States)

    Molina, Carlos; Prados-Suarez, Belén; Prados de Reyes, Miguel; Peña Yañez, Carmen


    In this paper we propose a new Classification based on Association Rules (CAR) algorithm that improves the interpretability of the results, works over real data from the electronic health records (EHRs), and allows the study of the patient as a whole. It enables tasks such as the discovery of relationships between diseases, or offering several alternative and reasoned diagnoses for the cases of patients with several diseases that analysed separately could lead to mistaken diagnosis. We aim to achieve several goals: to discover hidden relationships; to improve the interpretability and reduce the complexity of the result; to obtain more reliable diagnosis (getting alternative reasoned diagnoses and higher robustness to noisy rules), and to improve the quality of the classifier avoiding the usual over-fitting problem. To this purpose, we define and exploit hierarchies defined over datacubes dimensions, and change the way the association rules are obtained, and their evaluation at the classification process. To prove the utility of our proposal we have used it in an example of cancer discrimination.

  2. How can we improve the interpretation of systematic reviews?

    Full Text Available Abstract A study conducted by Lai and colleagues, published this week in BMC Medicine, suggests that more guidance might be required for interpreting systematic review (SR results. In the study by Lai and colleagues, positive (or favorable results were influential in changing participants' prior beliefs about the interventions presented in the systematic review. Other studies have examined the relationship between favorable systematic review results and the publication of systematic reviews. An international registry may decrease the number of unpublished systematic reviews and will hopefully decrease redundancy, increase transparency, and increase collaboration within the SR community. In addition, using guidance from the Preferred Items for Systematic Reviews and Meta-analyses (PRISMA: Statement and the Grading of Recommendations Assessment, Development, and Evaluation (GRADE: approach can also be used to improve the interpretation of systematic reviews. In this commentary, we highlight important methodological issues related to the conduct and reporting of systematic reviews and also present our own guidance on interpreting systematic reviews.

  3. Interpretations (United States)

    Bellac, Michel Le


    Although nobody can question the practical efficiency of quantum mechanics, there remains the serious question of its interpretation. As Valerio Scarani puts it, "We do not feel at ease with the indistinguishability principle (that is, the superposition principle) and some of its consequences." Indeed, this principle which pervades the quantum world is in stark contradiction with our everyday experience. From the very beginning of quantum mechanics, a number of physicists--but not the majority of them!--have asked the question of its "interpretation". One may simply deny that there is a problem: according to proponents of the minimalist interpretation, quantum mechanics is self-sufficient and needs no interpretation. The point of view held by a majority of physicists, that of the Copenhagen interpretation, will be examined in Section 10.1. The crux of the problem lies in the status of the state vector introduced in the preceding chapter to describe a quantum system, which is no more than a symbolic representation for the Copenhagen school of thought. Conversely, one may try to attribute some "external reality" to this state vector, that is, a correspondence between the mathematical description and the physical reality. In this latter case, it is the measurement problem which is brought to the fore. In 1932, von Neumann was first to propose a global approach, in an attempt to build a purely quantum theory of measurement examined in Section 10.2. This theory still underlies modern approaches, among them those grounded on decoherence theory, or on the macroscopic character of the measuring apparatus: see Section 10.3. Finally, there are non-standard interpretations such as Everett's many worlds theory or the hidden variables theory of de Broglie and Bohm (Section 10.4). Note, however, that this variety of interpretations has no bearing whatsoever on the practical use of quantum mechanics. There is no controversy on the way we should use quantum mechanics!

  4. Efficient Delaunay Tessellation through K-D Tree Decomposition

    Energy Technology Data Exchange (ETDEWEB)

    Morozov, Dmitriy; Peterka, Tom


    Delaunay tessellations are fundamental data structures in computational geometry. They are important in data analysis, where they can represent the geometry of a point set or approximate its density. The algorithms for computing these tessellations at scale perform poorly when the input data is unbalanced. We investigate the use of k-d trees to evenly distribute points among processes and compare two strategies for picking split points between domain regions. Because resulting point distributions no longer satisfy the assumptions of existing parallel Delaunay algorithms, we develop a new parallel algorithm that adapts to its input and prove its correctness. We evaluate the new algorithm using two late-stage cosmology datasets. The new running times are up to 50 times faster using k-d tree compared with regular grid decomposition. Moreover, in the unbalanced data sets, decomposing the domain into a k-d tree is up to five times faster than decomposing it into a regular grid.

The method is based on the fact that the initial CDM state can be described by a 3-D manifold (in a 6-D phase space) that remains con...

  7. Canaliculi in the tessellated skeleton of cartilaginous fishes

    Dean, M.N.; Socha, J.J.; Hall, B.K.; Summers, A.P. (UCI); (Dalhousie U.); (VPI-SU)


    The endoskeletal elements of sharks and rays are comprised of an uncalcified, hyaline cartilage-like core overlain by a thin fibro-ceramic layer of mineralized hexagonal tiles (tesserae) adjoined by intertesseral fibers. The basic spatial relationships of the constituent tissues (unmineralized cartilage, mineralized cartilage, fibrous tissue) are well-known - endoskeletal tessellation is a long-recognized synapomorphy of elasmobranch fishes - but a high-resolution and three-dimensional (3D) understanding of their interactions has been hampered by difficulties in sample preparation and lack of technologies adequate for visualizing microstructure and microassociations. We used cryo-electron microscopy and synchrotron radiation tomography to investigate tessellated skeleton ultrastructure but without damage to the delicate relationships between constituent tissues or to the tesserae themselves. The combination of these techniques allowed visualization of never before appreciated internal structures, namely passages connecting the lacunar spaces within tesserae. These intratesseral 'canaliculi' link consecutive lacunar spaces into long lacunar strings, radiating outward from the center of tesserae. The continuity of extracellular matrix throughout the canalicular network may explain how chondrocytes in tesserae remain vital despite encasement in mineral. Extracellular fluid exchange may also permit transmission of nutrients, and mechanical and mineralization signals among chondrocytes, in a manner similar to the canalicular network in bone. These co-adapted mechanisms for the facilitated exchange of extracellular material suggest a level of parallelism in early chondrocyte and osteocyte evolution.

  8. Interpretation and communication of medical evidence: room for improvement. (United States)

    Oyelese, Yinka; Vintzileos, Anthony


    Obstetricians often rely on the results of randomized studies and other medical evidence to guide them in treating patients. However, not infrequently, there are problems with the manner in which we communicate medical evidence to our patients and the public. For instance, we often rely almost exclusively on relative risks without discussing absolute risks. This has the potential to cause undue anxiety, misinterpretation, unrealistic expectations, and problems with clinical decision making. This commentary encourages a more critical look at the way we interpret data and communicate medical evidence to our patients and the public.

    Emerging microfluidic-based cell assays favor label-free red blood cell (RBC) depletion. Magnetic separation of RBC is possible because of the paramagnetism of deoxygenated hemoglobin but the process is slow for open-gradient field configurations. In order to increase the throughput, periodic arrangements of the unit magnets were considered, consisting of commercially available Nd-Fe-B permanent magnets and soft steel flux return pieces. The magnet design is uniquely suitable for multiplexing by magnet tessellation, here meaning the tiling of the magnet assembly cross-sectional plane by periodic repetition of the magnet and the flow channel shapes. The periodic pattern of magnet magnetizations allows a reduction of the magnetic material per channel with minimal distortion of the field cylindrical symmetry inside the magnet apertures. A number of such magnet patterns are investigated for separator performance, size and economy with the goal of designing an open-gradient magnetic separator capable of reducing the RBC number concentration a hundred-fold in 1 mL whole blood per hour. - Highlights: • Simple geometry of commercial, off-the-shelf NdFeB magnet blocks is amenable to generate high fields and open gradients. • Periodic pattern of permanent magnet blocks (tessellation) reduces the number of blocks per separation channel and improves the efficiency of separator design. • Split-flow lateral transport thin (SPLITT) fractionation model predicts 100-fold reduction of red blood cells from 1 mL whole blood sample in 1 h, suitable for laboratory medicine applications.

  10. Improved paleoenvironmental interpretations at the intersection between paleontology and biogeochemistry (United States)

    Lyons, T. W.


    Paleoenviromental reconstructions, particularly those focused of oxygen levels in the ancient ocean, often rely on geochemical or paleoecological approaches but too infrequently exploit the added strength that comes with a combined approach. Trace metal, organic biomarker, and iron paleoredox proxies do well in distinguishing between ancient oxic water columns and anoxic, Fe-rich (ferruginous) and anoxic, sulfidic (euxinic) settings. Molybdenum isotope approaches may even allow us to estimate the amount of hydrogen sulfide in the ancient seawater. Where the challenges often arise are at intermediate redox states marked by episodes of only transient anoxia/euxinia where diagnostic geochemical end-member enrichments are muted. Unfortunately, rapid detrital sedimentation and depleted seawater metal inventories under anoxic/euxinic conditions on basin and ocean scales can yield similarly tempered metal enrichments. Intermediate geochemical signatures can also mark conditions of extremely low bottom-water oxygen (often referred to as 'suboxic') but with sulfide confined to the pore fluids and a lack of appreciable and persistent Fe availability in the water column. Also possible are protracted episodes of true anoxia that lack Fe or sulfide in the water column because of limited availability of the organic matter required to drive bacterial Fe and sulfate reduction. In contrast, benthic ecological relationships, both trace and body fossil, are very sensitive to redox fluctuations at the low oxygen end, even brief episodes of oxygenation, and across subtle spatiotemporal redox gradients, although they are not readily effective at distinguishing between ferruginous and euxinic bottom waters. The talk will explore the mechanistic underpinnings of some of the most important geochemical proxies and then view their relative strengths and weaknesses in light of the added insight gleaned via coupled paleoecological analysis.

  11. Interpreting Disruption Prediction Models to Improve Plasma Control (United States)

    Parsons, Matthew


    In order for the tokamak to be a feasible design for a fusion reactor, it is necessary to minimize damage to the machine caused by plasma disruptions. Accurately predicting disruptions is a critical capability for triggering any mitigative actions, and a modest amount of attention has been given to efforts that employ machine learning techniques to make these predictions. By monitoring diagnostic signals during a discharge, such predictive models look for signs that the plasma is about to disrupt. Typically these predictive models are interpreted simply to give a `yes' or `no' response as to whether a disruption is approaching. However, it is possible to extract further information from these models to indicate which input signals are more strongly correlated with the plasma approaching a disruption. If highly accurate predictive models can be developed, this information could be used in plasma control schemes to make better decisions about disruption avoidance. This work was supported by a Grant from the 2016-2017 Fulbright U.S. Student Program, administered by the Franco-American Fulbright Commission in France.

  12. The interpreter as cultural educator of residents: improving communication for Latino parents. (United States)

    Wu, Ann Chen; Leventhal, John M; Ortiz, Jacqueline; Gonzalez, Ernesto E; Forsyth, Brian


    To determine whether augmentation of the Spanish interpreter's role to include cultural education of residents can improve the satisfaction of Latino patients. We assessed parent satisfaction during 4 sequential 2-month periods between June 1, 2004, and February 11, 2005, using different interpretation methods: telephone interpretation (n = 91 patient encounters), trained in-person interpretation (n = 49), in-person interpretation with cultural education of residents (n = 65), and postprogram telephone interpretation (n = 45). General pediatric practice at a large teaching hospital. A total of 250 Spanish-speaking parents who were limited in English proficiency. The cultural education program included 3 brief preclinic conferences taught by an interpreter and one-on-one teaching of residents about language and cultural issues after each clinical encounter. Parent satisfaction was assessed using 8 questions that have previously been validated in Spanish. Lower scores indicated more satisfaction. Because they were limited in English proficiency, our Spanish-speaking patients were significantly more satisfied when an in-person interpreter was used compared with a telephone interpreter (mean total satisfaction score of 14.5 [in-person] vs 17.4 [telephone]; P = .006) but were even more satisfied when the interpreter educated residents in cultural and language issues (mean, 11.5 [in-person with education] vs 17.4 [telephone]; Pinterpreter can increase Latino parents' satisfaction, a program using an interpreter to educate residents in cultural and language issues can increase satisfaction further.

  14. Peptide tessellation yields micrometre-scale collagen triple helices (United States)

    Tanrikulu, I. Caglar; Forticaux, Audrey; Jin, Song; Raines, Ronald T.


    Sticky-ended DNA duplexes can associate spontaneously into long double helices; however, such self-assembly is much less developed with proteins. Collagen is the most prevalent component of the extracellular matrix and a common clinical biomaterial. As for natural DNA, the ~103-residue triple helices (~300 nm) of natural collagen are recalcitrant to chemical synthesis. Here we show how the self-assembly of short collagen-mimetic peptides (CMPs) can enable the fabrication of synthetic collagen triple helices that are nearly a micrometre in length. Inspired by the mathematics of tessellations, we derive rules for the design of single CMPs that self-assemble into long triple helices with perfect symmetry. Sticky ends thus created are uniform across the assembly and drive its growth. Enacting this design yields individual triple helices that, in length, match or exceed those in natural collagen and are remarkably thermostable, despite the absence of higher-order association. The symmetric assembly of CMPs provides an enabling platform for the development of advanced materials for medicine and nanotechnology.

  15. Improving Breast Ultrasound Interpretation in Uganda Using a Condensed Breast Imaging Reporting and Data System. (United States)

    Scheel, John R; Peacock, Sue; Orem, Jackson; Bugeza, Samuel; Muyinda, Zeridah; Porter, Peggy L; Wood, William C; Comis, Robert L; Lehman, Constance D


    This study aimed to determine whether a 2-day educational course using a condensed Breast Imaging Reporting and Data System (condensed BI-RADS) improved the accuracy of Ugandan healthcare workers interpreting breast ultrasound. The target audience of this intervention was Ugandan healthcare workers involved in performing, interpreting, or acting on the results of breast ultrasound. The educational course consisted of a pretest knowledge assessment, a series of lectures on breast imaging interpretation and standardized reporting using a condensed BI-RADS, and a posttest knowledge assessment. Participants interpreted 53 different ultrasound test cases by selecting the finding type, descriptors for masses, and recommendations. We compared the percent correct on the pretest and posttest based on occupation and training level. Sixty-one Ugandan healthcare workers participated in this study, including 13 radiologists, 13 other physicians, 12 technologists, and 23 midlevel providers. Most groups improved in identifying the finding type (P breast ultrasound education using a condensed BI-RADS improved the interpretive performance of healthcare workers and was particularly successful in reducing the frequency of unnecessary biopsies for normal and benign findings. Multimodal educational efforts to improve accuracy and management of breast ultrasound findings may augment breast cancer early detection efforts in resource-limited settings.

    to correctly describe the local arrangements of grains (i.e., the grain neighbors and number of grain facets) for 31.8% of the investigated grains, the Laguerre tessellations were able to accurately describe statistical grain characteristics such as grain size distributions and grain neighbor distributions.......Accurate descriptions of 3D grain structures in polycrystalline materials are of key interest as the grain structure is closely correlated to the macroscopic properties of the material. In the present study, we investigate the accuracy of using Laguerre tessellations to represent 3D grain...... structures from only the spatial center of mass location and the volume of the grains. The ability of Laguerre tessellations to describe accurate grain shapes and topologies of real 3D grain structures are revealed by direct comparison to 3D reconstructions of an un-deformed meta-stable β -titanium alloy...

  19. Augmenting Amyloid PET Interpretations With Quantitative Information Improves Consistency of Early Amyloid Detection. (United States)

    Harn, Nicholas R; Hunt, Suzanne L; Hill, Jacqueline; Vidoni, Eric; Perry, Mark; Burns, Jeffrey M


    Establishing reliable methods for interpreting elevated cerebral amyloid-β plaque on PET scans is increasingly important for radiologists, as availability of PET imaging in clinical practice increases. We examined a 3-step method to detect plaque in cognitively normal older adults, focusing on the additive value of quantitative information during the PET scan interpretation process. Fifty-five F-florbetapir PET scans were evaluated by 3 experienced raters. Scans were first visually interpreted as having "elevated" or "nonelevated" plaque burden ("Visual Read"). Images were then processed using a standardized quantitative analysis software (MIMneuro) to generate whole brain and region of interest SUV ratios. This "Quantitative Read" was considered elevated if at least 2 of 6 regions of interest had an SUV ratio of more than 1.1. The final interpretation combined both visual and quantitative data together ("VisQ Read"). Cohen kappa values were assessed as a measure of interpretation agreement. Plaque was elevated in 25.5% to 29.1% of the 165 total Visual Reads. Interrater agreement was strong (kappa = 0.73-0.82) and consistent with reported values. Quantitative Reads were elevated in 45.5% of participants. Final VisQ Reads changed from initial Visual Reads in 16 interpretations (9.7%), with most changing from "nonelevated" Visual Reads to "elevated." These changed interpretations demonstrated lower plaque quantification than those initially read as "elevated" that remained unchanged. Interrater variability improved for VisQ Reads with the addition of quantitative information (kappa = 0.88-0.96). Inclusion of quantitative information increases consistency of PET scan interpretations for early detection of cerebral amyloid-β plaque accumulation.

  20. Stability of two-dimensional tessellation ice on the hydroxylated beta-cristobalite (100) surface. (United States)

    Lu, Zhong-Yuan; Sun, Zhao-Yan; Li, Ze-Sheng; An, Li-Jia


    Monolayer adsorbed water on the beta-cristobalite (100) surface is studied via classical molecular dynamics simulations. The ordered two-dimensional (2D) tessellation ice structure (i.e., the four-membered and the eight-membered rings appear alternatively) is justified at low temperatures in the simulations. The stability of this possible new ice phase is further investigated by heating the system from 5 to 300 K. An order-disorder structural transition is observed between 100 and 200 K, featuring the melting process of the tessellation ice. This process is characterized by the water oxygen-oxygen radial distribution function, the coordination number, the distance vector between the center of mass of the oxygen and the hydrogen atoms in water, the mean square displacement of oxygen in water, and the vibrational density of state. The above techniques show consistency on that the order-disorder transition temperature of the 2D tessellation ice is far below 300 K. The 2D tessellation ice structure is also obtained via density functional calculations with different generalized gradient approximations. By comparing the calculated adsorption and the lateral energies between different methods, we find that the melting temperature of the specific 2D ice structure is strongly method dependent. Therefore, further experimental works are urged to justify this possible new ice phase and probe its stability.

    Exeter, Daniel J; Elley, C Raina; Fulcher, Mark L; Lee, Arier C; Drezner, Jonathan A; Asif, Irfan M


    Screening to prevent sudden cardiac death remains a contentious topic in sport and exercise medicine. The aim of this study was to assess whether the use of a standardised criteria tool improves the accuracy of ECG interpretation by physicians screening athletes. Design: Randomised control trial. Study Population: General practitioners with an interest in sports medicine, sports physicians, sports medicine registrars and cardiologists from Australia and New Zealand were eligible to participate. Outcome Measures: Accuracy, sensitivity, specificity and false-positive rates of screening ECG interpretation of athletes. Intervention: A two-page standardised ECG criteria tool was provided to intervention participants. Control participants undertook 'usual' interpretation. 62 physicians, with a mean duration of practice of 16 years, were randomised to intervention and control. 10 baseline and 30 postrandomisation athlete ECGs were interpreted by the participants. Intervention participants were more likely to be correct: OR 1.72 (95% CI 1.31 to 2.27, pathletes can be improved by using a standardised ECG criteria tool. Use of the tool results in lower false-positive rates; this may have implications for screening recommendations. ACTRN12612000641897. Published by the BMJ Publishing Group Limited.

  4. Improving the Accuracy of CT Colonography Interpretation: Computer-Aided Diagnosis (United States)

    Summers, Ronald M.


    Synopsis Computer-aided polyp detection aims to improve the accuracy of the colonography interpretation. The computer searches the colonic wall to look for polyp-like protrusions and presents a list of suspicious areas to a physician for further analysis. Computer-aided polyp detection has developed rapidly over the past decade and in the laboratory setting and has sensitivities comparable to those of experts. Computer-aided polyp detection tends to help inexperienced readers more than experienced ones and may also lead to small reductions in specificity. In its currently proposed use as an adjunct to standard image interpretation, computer-aided polyp detection serves as a spellchecker rather than an efficiency enhancer. PMID:20451814

  5. High-Performance Computation of Distributed-Memory Parallel 3D Voronoi and Delaunay Tessellation

    Energy Technology Data Exchange (ETDEWEB)

    Peterka, Tom; Morozov, Dmitriy; Phillips, Carolyn


    Computing a Voronoi or Delaunay tessellation from a set of points is a core part of the analysis of many simulated and measured datasets: N-body simulations, molecular dynamics codes, and LIDAR point clouds are just a few examples. Such computational geometry methods are common in data analysis and visualization; but as the scale of simulations and observations surpasses billions of particles, the existing serial and shared-memory algorithms no longer suffice. A distributed-memory scalable parallel algorithm is the only feasible approach. The primary contribution of this paper is a new parallel Delaunay and Voronoi tessellation algorithm that automatically determines which neighbor points need to be exchanged among the subdomains of a spatial decomposition. Other contributions include periodic and wall boundary conditions, comparison of our method using two popular serial libraries, and application to numerous science datasets.

  6. Voronoi-Tessellated Graphite Produced by Low-Temperature Catalytic Graphitization from Renewable Resources. (United States)

    Zhao, Leyi; Zhao, Xiuyun; Burke, Luke T; Bennett, J Craig; Dunlap, Richard A; Obrovac, Mark N


    A highly crystalline graphite powder was prepared from the low temperature (800-1000 °C) graphitization of renewable hard carbon precursors using a magnesium catalyst. The resulting graphite particles are composed of Voronoi-tessellated regions comprising irregular sheets; each Voronoi-tessellated region having a small "seed" particle located near their centroid on the surface. This suggests nucleated outward growth of graphitic carbon, which has not been previously observed. Each seed particle consists of a spheroidal graphite shell on the inside of which hexagonal graphite platelets are perpendicularly affixed. This results in a unique high surface area graphite with a high degree of graphitization that is made with renewable feedstocks at temperatures far below that conventionally used for artificial graphites. © 2017 Wiley-VCH Verlag GmbH & Co.

  7. Curvature, metric and parametrization of origami tessellations: theory and application to the eggbox pattern (United States)

    Nassar, H.; Lebée, A.; Monasse, L.


    Origami tessellations are particular textured morphing shell structures. Their unique folding and unfolding mechanisms on a local scale aggregate and bring on large changes in shape, curvature and elongation on a global scale. The existence of these global deformation modes allows for origami tessellations to fit non-trivial surfaces thus inspiring applications across a wide range of domains including structural engineering, architectural design and aerospace engineering. The present paper suggests a homogenization-type two-scale asymptotic method which, combined with standard tools from differential geometry of surfaces, yields a macroscopic continuous characterization of the global deformation modes of origami tessellations and other similar periodic pin-jointed trusses. The outcome of the method is a set of nonlinear differential equations governing the parametrization, metric and curvature of surfaces that the initially discrete structure can fit. The theory is presented through a case study of a fairly generic example: the eggbox pattern. The proposed continuous model predicts correctly the existence of various fittings that are subsequently constructed and illustrated.

  8. Adaptive acoustic energy delivery to near and far fields using foldable, tessellated star transducers (United States)

    Zou, Chengzhe; Harne, Ryan L.


    Methods of guiding acoustic energy arbitrarily through space have long relied on digital controls to meet performance needs. Yet, more recent attention to adaptive structures with unique spatial configurations has motivated mechanical signal processing (MSP) concepts that may not be subjected to the same functional and performance limitations as digital acoustic beamforming counterparts. The periodicity of repeatable structural reconfiguration enabled by origami-inspired tessellated architectures turns attention to foldable platforms as frameworks for MSP development. This research harnesses principles of MSP to study a tessellated, star-shaped acoustic transducer constituent that provides on-demand control of acoustic energy guiding via folding-induced shape reconfiguration. An analytical framework is established to probe the roles of mechanical and acoustic geometry on the far field directivity and near field focusing of sound energy. Following validation by experiments and verification by simulations, parametric studies are undertaken to uncover relations between constituent topology and acoustic energy delivery to arbitrary points in the free field. The adaptations enabled by folding of the star-shaped transducer reveal capability for restricting sound energy to angular regions in the far field while also introducing means to modulate sound energy by three orders-of-magnitude to locations near to the transducer surface. In addition, the modeling philosophy devised here provides a valuable approach to solve general sound radiation problems for foldable, tessellated acoustic transducer constituents of arbitrary geometry.

  9. Improving interpretation of infrared spectra for OM characterization by subtraction of spectra from incinerated samples (United States)

    Ellerbrock, Ruth H.; Gerke, Horst H.; Leue, Martin


    Non-destructive methods such as diffuse reflectance infrared Fourier transform spectroscopy (DRIFT) have been applied to characterize organic matter (OM) at intact structural surfaces among others. However, it is often difficult to distinguish effects of organic components on DRIFT signal intensities from those of mineral components. The objective of this study was to re-evaluate DRIFT spectra from intact earthworm burrow walls and coated cracks to improve the interpretation of C-H and C=O bands. We compared DRIFT and transmission Fourier transform infrared (FTIR) spectra of entire samples that were from the same pedogenetic soil horizon, but different in mineral composition and texture (i.e., glacial till versus loess). Spectra of incinerated samples were subtracted from the original spectra. Transmission FTIR and DRIFT spectra were almost identical for entire soil samples. However, the DRIFT spectra were affected by the bulk mode bands (i.e., wavenumbers 2000 to 1700 cm-1) that affected spectral resolution and reproducibility. The ratios between C-H and C=O band intensities as indicator for OM quality obtained with DRIFT were smaller than those obtained from transmission FTIR. A spectral subtraction procedure was found to reduce effects of mineral absorption bands on DRIFT spectra allowing an improved interpretation. DRIFT spectroscopy as a non-destructive method for analyzing OM composition at intact surfaces in structured soils could be calibrated with information obtained with the more detailed transmission FTIR and complementary methods.

  10. Ontogeny, morphology and mechanics of the tessellated skeleton of cartilaginous fishes (United States)

    Dean, Mason N.


    The members of the successful and diverse lineage of elasmobranch fishes (sharks, rays and relatives) possess endoskeletons fashioned entirely of cartilage. This is counterintuitive because cartilage, unlike bone, lacks a major blood supply and has limited capacity for repair; yet these fishes exhibit particularly dynamic lifestyles and high levels of performance. The functionality of this skeletal tissue is likely due to its mineralization: in most skeletal elements, the soft cartilage core is tiled (tessellated) with an outer rind of abutting hydroxyapatite blocks called tesserae, joined together by intertesseral fibers and overlain by the fibrous perichondrium. This basic composite arrangement of tissues has been appreciated for over a century, but available techniques have limited the ability to examine elasmobranch cartilage adequately---without artifacts, in 3-dimensions and at high resolution---so that its development, mechanics and phylogeny might be contextualized among vertebrate skeletal tissues. I summarize the history, nomenclature and challenges relating to study of tessellated cartilage (Chapter 1) and present a low temperature microscopy technique to facilitate visualization of all tissue components in situ (Chapter 2). I use that technique in tandem with synchrotron microtomography to examine the ultrastructure of tesserae (Chapter 3) and the development of tessellated cartilage across ontogeny (Chapter 4). Finally, I examine the ways in which selection acts on skeletal morphology by examining cranial anatomy across 40 species of batoid fishes (rays and relatives) in the contexts of ecology and phylogeny (Chapter 5). There are some similarities between mineralizing bone and elasmobranch cartilage (e.g. the flattening of peripheral cells in the unmineralized phase, decreases in cellular density with mineralization, the presence of canaliculi connecting entombed cells). However, the ability for tessellated cartilage to grow (through enlargement of

    Pourmand, Ali; Tanski, Mary; Davis, Steven; Shokoohi, Hamid; Lucas, Raymond; Zaver, Fareen


    Asynchronous online training has become an increasingly popular educational format in the new era of technology-based professional development. We sought to evaluate the impact of an online asynchronous training module on the ability of medical students and emergency medicine (EM) residents to detect electrocardiogram (ECG) abnormalities of an acute myocardial infarction (AMI). We developed an online ECG training and testing module on AMI, with emphasis on recognizing ST elevation myocardial infarction (MI) and early activation of cardiac catheterization resources. Study participants included senior medical students and EM residents at all post-graduate levels rotating in our emergency department (ED). Participants were given a baseline set of ECGs for interpretation. This was followed by a brief interactive online training module on normal ECGs as well as abnormal ECGs representing an acute MI. Participants then underwent a post-test with a set of ECGs in which they had to interpret and decide appropriate intervention including catheterization lab activation. 148 students and 35 EM residents participated in this training in the 2012-2013 academic year. Students and EM residents showed significant improvements in recognizing ECG abnormalities after taking the asynchronous online training module. The mean score on the testing module for students improved from 5.9 (95% CI [5.7-6.1]) to 7.3 (95% CI [7.1-7.5]), with a mean difference of 1.4 (95% CI [1.12-1.68]) (p<0.0001). The mean score for residents improved significantly from 6.5 (95% CI [6.2-6.9]) to 7.8 (95% CI [7.4-8.2]) (p<0.0001). An online interactive module of training improved the ability of medical students and EM residents to correctly recognize the ECG evidence of an acute MI.

  13. Improved Geologic Interpretation of Non-invasive Electrical Resistivity Imaging from In-situ Samples (United States)

    Mucelli, A.; Aborn, L.; Jacob, R.; Malusis, M.; Evans, J.


    Non-invasive geophysical techniques are useful in characterizing the subsurface geology without disturbing the environment, however, the ability to interpret the subsurface is enhanced by invasive work. Since geologic materials have electrical resistivity values it allows for a geologic interpretation to be made based on variations of electrical resistivity measured by electrical resistivity imaging (ERI). This study focuses on the pre-characterization of the geologic subsurface from ERI collected adjacent to the Montandon Marsh, a wetland located near Lewisburg, PA within the West Branch of the Susquehanna River watershed. The previous invasive data, boreholes, indicate that the subsurface consists of limestone and shale bedrock overlain with sand and gravel deposits from glacial outwash and aeolian processes. The objective is to improve our understanding of the subsurface at this long-term hydrologic research site by using excavation results, specifically observed variations in geologic materials and electrical resistivity laboratory testing of subsurface samples. The pre-excavation ERI indicated that the shallow-most geologic material had a resistivity value of 100-500 ohm-m. In comparison, the laboratory testing indicated the shallow-most material had the same range of electrical resistivity values depending on saturation levels. The ERI also showed that there was an electrically conductive material, 7 to 70 ohm-m, that was interpreted to be clay and agreed with borehole data, however, the excavation revealed that at this depth range the geologic material varied from stratified clay to clay with cobbles to weathered residual clay. Excavation revealed that the subtle variations in the electrical conductive material corresponded well with the variations in the geologic material. We will use these results to reinterpret previously collected ERI data from the entire long-term research site.

  14. Bridging the language gap: a co-designed quality improvement project to engage professional interpreters for women during labour. (United States)

    Yelland, Jane; Biro, Mary Anne; Dawson, Wendy; Riggs, Elisha; Vanpraag, Dannielle; Wigg, Karen; Antonopoulos, John; Morgans, Jenny; Szwarc, Jo; East, Chris; Brown, Stephanie


    Objective The aim of the study was to improve the engagement of professional interpreters for women during labour. Methods The quality improvement initiative was co-designed by a multidisciplinary group at one Melbourne hospital and implemented in the birth suite using the plan-do-study-act framework. The initiative of offering women an interpreter early in labour was modified over cycles of implementation and scaled up based on feedback from midwives and language services data. Results The engagement of interpreters for women identified as requiring one increased from 28% (21/74) at baseline to 62% (45/72) at the 9th month of implementation. Conclusion Improving interpreter use in high-intensity hospital birth suites is possible with supportive leadership, multidisciplinary co-design and within a framework of quality improvement cycles of change. What is known about the topic? Despite Australian healthcare standards and policies stipulating the use of accredited interpreters where needed, studies indicate that services fall well short of meeting these during critical stages of childbirth. What does the paper add? Collaborative approaches to quality improvement in hospitals can significantly improve the engagement of interpreters to facilitate communication between health professionals and women with low English proficiency. What are the implications for practice? This language services initiative has potential for replication in services committed to improving effective communication between health professionals and patients.

  15. An Efficient Data Partitioning to Improve Classification Performance While Keeping Parameters Interpretable.

    Directory of Open Access Journals (Sweden)

    Kristjan Korjus

    Full Text Available Supervised machine learning methods typically require splitting data into multiple chunks for training, validating, and finally testing classifiers. For finding the best parameters of a classifier, training and validation are usually carried out with cross-validation. This is followed by application of the classifier with optimized parameters to a separate test set for estimating the classifier's generalization performance. With limited data, this separation of test data creates a difficult trade-off between having more statistical power in estimating generalization performance versus choosing better parameters and fitting a better model. We propose a novel approach that we term "Cross-validation and cross-testing" improving this trade-off by re-using test data without biasing classifier performance. The novel approach is validated using simulated data and electrophysiological recordings in humans and rodents. The results demonstrate that the approach has a higher probability of discovering significant results than the standard approach of cross-validation and testing, while maintaining the nominal alpha level. In contrast to nested cross-validation, which is maximally efficient in re-using data, the proposed approach additionally maintains the interpretability of individual parameters. Taken together, we suggest an addition to currently used machine learning approaches which may be particularly useful in cases where model weights do not require interpretation, but parameters do.

  16. Competition on the rocks: community growth and tessellation.

    Directory of Open Access Journals (Sweden)

    Espen Jettestuen

    Full Text Available Crustose lichen communities on rocks exhibit fascinating spatial mosaics resembling political maps of nations or municipalities. Although the establishment and development of biological populations are important themes in ecology, our understanding of the formation of such patterns on the rocks is still in its infancy. Here, we present a novel model of the concurrent growth, establishment and interaction of lichens. We introduce an inverse technique based on Monte Carlo simulations to test our model on field samples of lichen communities. We derive an expression for the time needed for a community to cover a surface and predict the historical spatial dynamics of field samples. Lichens are frequently used for dating the time of exposure of rocks in glacial deposits, lake retreats or rock falls. We suggest our method as a way to improve the dating.

  17. ECG interpretation in Emergency Department residents: an update and e-learning as a resource to improve skills. (United States)

    Barthelemy, Francois X; Segard, Julien; Fradin, Philippe; Hourdin, Nicolas; Batard, Eric; Pottier, Pierre; Potel, Gilles; Montassier, Emmanuel


    ECG interpretation is a pivotal skill to acquire during residency, especially for Emergency Department (ED) residents. Previous studies reported that ECG interpretation competency among residents was rather low. However, the optimal resource to improve ECG interpretation skills remains unclear. The aim of our study was to compare two teaching modalities to improve the ECG interpretation skills of ED residents: e-learning and lecture-based courses. The participants were first-year and second-year ED residents, assigned randomly to the two groups. The ED residents were evaluated by means of a precourse test at the beginning of the study and a postcourse test after the e-learning and lecture-based courses. These evaluations consisted of the interpretation of 10 different ECGs. We included 39 ED residents from four different hospitals. The precourse test showed that the overall average score of ECG interpretation was 40%. Nineteen participants were then assigned to the e-learning course and 20 to the lecture-based course. Globally, there was a significant improvement in ECG interpretation skills (accuracy score=55%, P=0.0002). However, this difference was not significant between the two groups (P=0.14). Our findings showed that the ECG interpretation was not optimal and that our e-learning program may be an effective tool for enhancing ECG interpretation skills among ED residents. A large European study should be carried out to evaluate ECG interpretation skills among ED residents before the implementation of ECG learning, including e-learning strategies, during ED residency.

  18. Occupational exposure decisions: can limited data interpretation training help improve accuracy? (United States)

    Logan, Perry; Ramachandran, Gurumurthy; Mulhausen, John; Hewett, Paul


    Accurate exposure assessments are critical for ensuring that potentially hazardous exposures are properly identified and controlled. The availability and accuracy of exposure assessments can determine whether resources are appropriately allocated to engineering and administrative controls, medical surveillance, personal protective equipment and other programs designed to protect workers. A desktop study was performed using videos, task information and sampling data to evaluate the accuracy and potential bias of participants' exposure judgments. Desktop exposure judgments were obtained from occupational hygienists for material handling jobs with small air sampling data sets (0-8 samples) and without the aid of computers. In addition, data interpretation tests (DITs) were administered to participants where they were asked to estimate the 95th percentile of an underlying log-normal exposure distribution from small data sets. Participants were presented with an exposure data interpretation or rule of thumb training which included a simple set of rules for estimating 95th percentiles for small data sets from a log-normal population. DIT was given to each participant before and after the rule of thumb training. Results of each DIT and qualitative and quantitative exposure judgments were compared with a reference judgment obtained through a Bayesian probabilistic analysis of the sampling data to investigate overall judgment accuracy and bias. There were a total of 4386 participant-task-chemical judgments for all data collections: 552 qualitative judgments made without sampling data and 3834 quantitative judgments with sampling data. The DITs and quantitative judgments were significantly better than random chance and much improved by the rule of thumb training. In addition, the rule of thumb training reduced the amount of bias in the DITs and quantitative judgments. The mean DIT % correct scores increased from 47 to 64% after the rule of thumb training (P rule of thumb

  19. Integrated interpretation to improve subsalt imaging: a case study from the Nordkapp Basin, Norwegian Barents Sea (United States)

    Olaf Müller, Christian; Brönner, Marco; Götze, Hans-Jürgen


    Seismic imaging of subsalt structures is still a difficult task and remaining uncertanties in the salt geometries makes exploration in the vicinity of such complex structures challenging. Gravity and magnetic data have proofed in the past their potential in combination with seismics to better delineate the shape of such salt structures. The current work deals with the improvement of subsalt imaging by combined interpretation of seismic and potential field data examined at a case study from the southern Nordkapp Basin. The Nordkapp Basin is a deep, narrow saliferous basin located in the southwestern Barents Sea. It comprises more than 30 salt diapirs, which are likely to create traps for hydrocarbons at their flanks and overhangs. Consequently exploration of the Nordkapp Basin with seismic methods started already in the 1980s, but until today solely seismics was not sufficient to reveal the nature and geometry for large parts of the basin. Therefore 2D and 3D seismic data were interpreted and used as stratigraphic constraints for the potential field modeling. For this purpose high resolution gravity and full tensor gravity gradient (FTG) data as well as a regional magnetic dataset were available. After processing the potential field data the 3D modeling was conducted by means of the interactive gravity and magnetic modeling software IGMAS+. Furthermore constraints for the rock properties, provided by well logs and susceptibility measurements of adjacent sedimentary well cores, were integrated. The favoured models indicate for both major salt structures a bulky base and a small root. The depth of the base of salt can vary in a range of about ± 300 m. Remaining mother salt is found in the northern part of the survey area and has no connection to the diapiric salt. Due to its higher sensibility to shallower sources the FTG data was used to model the flanks of the salt diapirs. In agreement with adjacent diapirs and encountered sequences a cap rock coverage was

  20. A program for analyzing the morphological organization of tessellated cellular mosaics. (United States)

    Dilts, D M; Doughty, M J


    We have constructed a computer program that allows sequential sets of data from tessellated cellular mosaics to be evaluated such that the presence and position of abnormal cells in the mosaic can be easily, quickly, and quantitatively identified. Conventional parametric analysis of the global morphological organization of large tessellated cellular mosaics does not provide the necessary granularity of analysis to allow for rapid identification of such atypical cellular structures. Our program, written in C using structured programming techniques, provides the needed analytical granularity for detailed studies of subsections of large cellular mosaics, while also providing conventional statistical evaluation of the data set. The architecture of the program is modular and designed as a set of procedures and subprocessess that can either analyze the entire mosaic or discrete sets of cells within the larger sample. The types of morphological heterogeneity (or dishomogeneity) that the program can investigate occur in a variety of biological mosaics where there is a continuum of the structural features, including fairly regular linear stacked arrays of cells or tissue partitions, to less regular mosaics of epithelial or endothelial cell layers, to heterogeneous patterns found on tissue surfaces, such as fluorescein dye-highlighted features on the human conjunctiva. The program has been used to successfully evaluate several different types of mosaics.

  1. ColDICE: a parallel Vlasov-Poisson solver using moving adaptive simplicial tessellation

    CERN Document Server

    Sousbie, Thierry


    Resolving numerically Vlasov-Poisson equations for initially cold systems can be reduced to following the evolution of a three-dimensional sheet evolving in six-dimensional phase-space. We describe a public parallel numerical algorithm consisting in representing the phase-space sheet with a conforming, self-adaptive simplicial tessellation of which the vertices follow the Lagrangian equations of motion. The algorithm is implemented both in six- and four-dimensional phase-space. Refinement of the tessellation mesh is performed using the bisection method and a local representation of the phase-space sheet at second order relying on additional tracers created when needed at runtime. In order to preserve in the best way the Hamiltonian nature of the system, refinement is anisotropic and constrained by measurements of local Poincar\\'e invariants. Resolution of Poisson equation is performed using the fast Fourier method on a regular rectangular grid, similarly to particle in cells codes. To compute the density proj...

  2. Vapor-liquid equilibrium of ethanol by molecular dynamics simulation and Voronoi tessellation. (United States)

    Fern, Jared T; Keffer, David J; Steele, William V


    Explicit atom simulations of ethanol were performed by molecular dynamics using the OPLS-AA potential. The phase densities were determined self-consistently by comparing the distribution of Voronoi volumes from two-phase and single-phase simulations. This is the first demonstration of the use of Voronoi tessellation in two-phase molecular dynamics simulation of polyatomic fluids. This technique removes all arbitrary determination of the phase diagram by using single-phase simulations to self-consistently validate the probability distribution of Voronoi volumes of the liquid and vapor phases extracted from the two-phase molecular dynamics simulations. Properties from the two phase simulations include critical temperature, critical density, critical pressure, phase diagram, surface tension, and molecule orientation at the interface. The simulations were performed from 375 to 472 K. Also investigated were the vapor pressure and hydrogen bonding along the two phase envelope. The phase envelope agrees extremely well with literature values from GEMC at lower temperatures. The combined use of two-phase molecular dynamics simulation and Voronoi tessellation allows us to extend the phase diagram toward the critical point.

  5. Hurricane signatures and landforms—toward improved interpretations and global storm climate chronology (United States)

    Otvos, Ervin G.


    The correct understanding of the geological and geomorphic evolution of paralic basins and coastal barriers is a prerequisite for establishing Holocene hurricane archives worldwide. Detection and documentation of hurricane signatures in coastal deposits are becoming instrumental in attempts to reconstruct mid and late Holocene storm climate history. Subsurface exploration and field studies on the NE Gulf coast and data gleaned from the literature suggest the need for a complex approach that provides well-documented details of coastal landscape evolution. Until recently, prehistoric hurricanes and their intensity levels have been automatically interpreted from the frequency and thickness of sand layers in muddy paralic deposits. However, in addition to wind velocity, several hydro-, aerodynamic, and other factors a wide range of stratigraphic conditions, topographic setting, and sand sources also determine variations in the extent and intensity of storm flooding, erosion, transfer, and deposition of sand layers in small paralic basins. Inherent limitations in these sedimentary records and their interpretation must be overcome in order to improve local hurricane chronologies and establish interregional correlations. Before sedimentary and chemical signatures are accepted as diagnostic indicators of overwash especially by "catastrophic" hurricanes, alternative causes must also be considered. A parallel scale of storm flood-level stages should supplement the Saffir-Simpson hurricane categories. The relationship between storm intensities and flooding elevations is highly complex. Changes in sea-level, shore positions, formation and extinction of preexisting incised valley networks, the impact of transgression and regression processes on estuaries and their deposits play determining roles in setting the stage for overwash processes. Strandplain progradation followed by erosive shore retreat played a key role in framing certain paralic lakes. Without overwash, sand layers

    Rationale and objectives: Current radiology practice increasingly involves interpretation of volumetric data sets. In contrast, most radiology tests still contain only 2D images. We introduced a new testing tool that allows for stack viewing of volumetric images in our undergraduate radiology program. We hypothesized that tests with volumetric CT-images enhance test quality, in comparison with traditional completely 2D image-based tests, because they might better reflect required skills for clinical practice. Materials and methods: Two groups of medical students (n = 139; n = 143), trained with 2D and volumetric CT-images, took a digital radiology test in two versions (A and B), each containing both 2D and volumetric CT-image questions. In a questionnaire, they were asked to comment on the representativeness for clinical practice, difficulty and user-friendliness of the test questions and testing program. Students’ test scores and reliabilities, measured with Cronbach's alpha, of 2D and volumetric CT-image tests were compared. Results: Estimated reliabilities (Cronbach's alphas) were higher for volumetric CT-image scores (version A: .51 and version B: .54), than for 2D CT-image scores (version A: .24 and version B: .37). Participants found volumetric CT-image tests more representative of clinical practice, and considered them to be less difficult than volumetric CT-image questions. However, in one version (A), volumetric CT-image scores (M 80.9, SD 14.8) were significantly lower than 2D CT-image scores (M 88.4, SD 10.4) (p < .001). The volumetric CT-image testing program was considered user-friendly. Conclusion: This study shows that volumetric image questions can be successfully integrated in students’ radiology testing. Results suggests that the inclusion of volumetric CT-images might improve the quality of radiology tests by positively impacting perceived representativeness for clinical practice and increasing reliability of the test.

  7. On Improving the Quality and Interpretation of Environmental Assessments using Statistical Analysis and Geographic Information Systems (United States)

    Karuppiah, R.; Faldi, A.; Laurenzi, I.; Usadi, A.; Venkatesh, A.


    An increasing number of studies are focused on assessing the environmental footprint of different products and processes, especially using life cycle assessment (LCA). This work shows how combining statistical methods and Geographic Information Systems (GIS) with environmental analyses can help improve the quality of results and their interpretation. Most environmental assessments in literature yield single numbers that characterize the environmental impact of a process/product - typically global or country averages, often unchanging in time. In this work, we show how statistical analysis and GIS can help address these limitations. For example, we demonstrate a method to separately quantify uncertainty and variability in the result of LCA models using a power generation case study. This is important for rigorous comparisons between the impacts of different processes. Another challenge is lack of data that can affect the rigor of LCAs. We have developed an approach to estimate environmental impacts of incompletely characterized processes using predictive statistical models. This method is applied to estimate unreported coal power plant emissions in several world regions. There is also a general lack of spatio-temporal characterization of the results in environmental analyses. For instance, studies that focus on water usage do not put in context where and when water is withdrawn. Through the use of hydrological modeling combined with GIS, we quantify water stress on a regional and seasonal basis to understand water supply and demand risks for multiple users. Another example where it is important to consider regional dependency of impacts is when characterizing how agricultural land occupation affects biodiversity in a region. We developed a data-driven methodology used in conjuction with GIS to determine if there is a statistically significant difference between the impacts of growing different crops on different species in various biomes of the world.

  12. Improving visual observation skills through the arts to aid radiographic interpretation in veterinary practice: A pilot study. (United States)

    Beck, Cathy; Gaunt, Heather; Chiavaroli, Neville


    Radiographic interpretation is a perceptual and cognitive skill. Recently core veterinary radiology textbooks have focused on the cognitive (i.e., the clinical aspects of radiographic interpretation) rather than the features of visual observation that improve identification of abnormalities. As a result, the skill of visual observation is underemphasized and thus often underdeveloped by trainees. The study of the arts in medical education has been used to train and improve visual observation and empathy. The use of the arts to improve visual observation skills in Veterinary Science has not been previously described. Objectives of this pilot study were to adapt the existing Visual Arts in Health Education Program for medical and dental students at the University of Melbourne, Australia to third year Doctor of Veterinary Medicine students and evaluate their perceptions regarding the program's effects on visual observation skills and confidence with respect to radiographic interpretation. This adaptation took the form of a single seminar given to third year Doctor of Veterinary Medicine students. Following the seminar, students reported an improved approach to radiographic interpretation and felt they had gained skills which would assist them throughout their career. In the year following the seminar, written reports of the students who attended the seminar were compared with reports from a matched cohort of students who did not attend the seminar. This demonstrated increased identification of abnormalities and greater description of the abnormalities identified. Findings indicated that explicit training in visual observation may be a valuable adjunct to the radiology training of Doctor of Veterinary Medicine students. © 2017 American College of Veterinary Radiology.

Owing to the abstract nature of the basic theoretical knowledge of the ECG, its scattered characteristics, and tedious and difficult-to-remember subject matter, teaching how to interpret ECGs is as difficult for teachers to teach as it is for students to learn. In order to enable medical students to master basic knowledge of ECG interpretation skills in a limited teaching time, we modified the content used for traditional ECG teaching and now propose a new ECG teaching method called the “graphics-sequence memory method.” Methods: A prospective randomized controlled study was designed to measure the actual effectiveness of ECG learning by students. Two hundred students were randomly placed under a traditional teaching group and an innovative teaching group, with 100 participants in each group. The teachers in the traditional teaching group utilized the traditional teaching outline, whereas the teachers in the innovative teaching group received training in line with the proposed teaching method and syllabus. All the students took an examination in the final semester by analyzing 20 ECGs from real clinical cases and submitted their ECG reports. Results: The average ECG reading time was 32 minutes for the traditional teaching group and 18 minutes for the innovative teaching group. The average ECG accuracy results were 43% for the traditional teaching group and 77% for the innovative teaching

  14. How can we improve teaching of ECG interpretation skills? Findings from a prospective randomised trial. (United States)

    Raupach, T; Harendza, S; Anders, S; Schuelper, N; Brown, J


    There is an ongoing debate on how ECG interpretation should be taught during undergraduate medical training. This study addressed the impact of teaching format, examination consequences and student motivation on skills retention. A total of 493 fourth-year medical students participated in a six-group, partially randomised trial. Students received three levels of teaching intensity: self-directed learning (2 groups), lectures (2 groups) or small-group peer-teaching (2 groups). On each level of teaching intensity, end-of-course written examinations (ECG exit exam) were summative in one group and formative in the other. Learning outcome was assessed in a retention test two months later. Retention test scores were predicted by summative assessments (adjusted beta 4.08; 95% CI 1.39-6.78) but not by the type of teaching. Overall performance levels and motivation did not predict performance decrease or skills retention. Summative assessments increase medium-term retention of ECG interpretation skills, irrespective of instructional format. Copyright © 2016. Published by Elsevier Inc.

  16. Adaptive geometric tessellation for 3D reconstruction of anisotropically developing cells in multilayer tissues from sparse volumetric microscopy images.

    Directory of Open Access Journals (Sweden)

    Anirban Chakraborty

    Full Text Available The need for quantification of cell growth patterns in a multilayer, multi-cellular tissue necessitates the development of a 3D reconstruction technique that can estimate 3D shapes and sizes of individual cells from Confocal Microscopy (CLSM image slices. However, the current methods of 3D reconstruction using CLSM imaging require large number of image slices per cell. But, in case of Live Cell Imaging of an actively developing tissue, large depth resolution is not feasible in order to avoid damage to cells from prolonged exposure to laser radiation. In the present work, we have proposed an anisotropic Voronoi tessellation based 3D reconstruction framework for a tightly packed multilayer tissue with extreme z-sparsity (2-4 slices/cell and wide range of cell shapes and sizes. The proposed method, named as the 'Adaptive Quadratic Voronoi Tessellation' (AQVT, is capable of handling both the sparsity problem and the non-uniformity in cell shapes by estimating the tessellation parameters for each cell from the sparse data-points on its boundaries. We have tested the proposed 3D reconstruction method on time-lapse CLSM image stacks of the Arabidopsis Shoot Apical Meristem (SAM and have shown that the AQVT based reconstruction method can correctly estimate the 3D shapes of a large number of SAM cells.

  17. An Improved Method for Interpretation of Concentration-Discharge Relationships in Riverine Water-Quality Data (United States)

    Zhang, Q.; Harman, C. J.; Ball, W. P.


    Riverine concentration-discharge (C-Q) relationships are powerful indicators that can provide important clues toward understanding nutrient and sediment export dynamics from river systems, and the analysis of such relations has been a long-standing topic of importance in hydrologic literature. Proper interpretation of such relationships can be made complex, however, if the relationships of ln(C) ln(Q) are nonlinear or if the relationships change over time, season, or discharge. Methods of addressing these issues by "binning" data or smoothing trends can introduce artifacts and ambiguities that obscure underlying interactions among time, discharge, and season. Here we illustrate these issues with examples and propose an alternative method that uses the regression coefficients of the recently-developed WRTDS ("Weighted Regressions on Time, Discharge, and Season") model for examining riverine C-Q relationships, including their uncertainty. The method is applied to sediment concentration data from Susquehanna River at Conowingo Dam (Maryland, USA) to illustrate how the WRTDS coefficients can be accessed and presented in ways that provide additional insights toward the interpretation of river water-quality data. For this case, the results clearly reveal that sediment concentration in the reservoir effluent has become more sensitive to discharge at moderate and high flows (but not very low flows) as it approaches sediment storage capacity, reaffirming the recently-documented decadal-scale decline in reservoir trapping performance. The study also highlights an additional benefit of the method, which is the ability to perform uncertainty analyses. The proposed approach can be implemented by running additional R codes within the WRTDS software - such codes are made available to users through a DOI-referenced archive site ( that will be maintained for at least five years after publication.

  18. Using Delaunay triangulation and Voronoi tessellation to predict the toxicities of binary mixtures containing hormetic compound. (United States)

    Qu, Rui; Liu, Shu-Shen; Zheng, Qiao-Feng; Li, Tong


    Concentration addition (CA) was proposed as a reasonable default approach for the ecological risk assessment of chemical mixtures. However, CA cannot predict the toxicity of mixture at some effect zones if not all components have definite effective concentrations at the given effect, such as some compounds induce hormesis. In this paper, we developed a new method for the toxicity prediction of various types of binary mixtures, an interpolation method based on the Delaunay triangulation (DT) and Voronoi tessellation (VT) as well as the training set of direct equipartition ray design (EquRay) mixtures, simply IDVequ. At first, the EquRay was employed to design the basic concentration compositions of five binary mixture rays. The toxic effects of single components and mixture rays at different times and various concentrations were determined by the time-dependent microplate toxicity analysis. Secondly, the concentration-toxicity data of the pure components and various mixture rays were acted as a training set. The DT triangles and VT polygons were constructed by various vertices of concentrations in the training set. The toxicities of unknown mixtures were predicted by the linear interpolation and natural neighbor interpolation of vertices. The IDVequ successfully predicted the toxicities of various types of binary mixtures.

    Language barriers disrupt communication and impede informed consent for patients with limited English proficiency (LEP) undergoing healthcare procedures. Effective interventions for this disparity remain unclear. Assess the impact of a bedside interpreter phone system intervention on informed consent for patients with LEP and compare outcomes to those of English speakers. Prospective, pre-post intervention implementation study using propensity analysis. Hospitalized patients undergoing invasive procedures on the cardiovascular, general surgery or orthopedic surgery floors. Installation of dual-handset interpreter phones at every bedside enabling 24-h immediate access to professional interpreters. Primary predictor: pre- vs. post-implementation group; secondary predictor: post-implementation patients with LEP vs. English speakers. Primary outcomes: three central informed consent elements, patient-reported understanding of the (1) reasons for and (2) risks of the procedure and (3) having had all questions answered. We considered consent adequately informed when all three elements were met. We enrolled 152 Chinese- and Spanish-speaking patients with LEP (84 pre- and 68 post-implementation) and 86 English speakers. Post-implementation (vs. pre-implementation) patients with LEP were more likely to meet criteria for adequately informed consent (54% vs. 29%, p = 0.001) and, after propensity score adjustment, had significantly higher odds of adequately informed consent (AOR 2.56; 95% CI, 1.15-5.72) as well as of each consent element individually. However, compared to post-implementation English speakers, post-implementation patients with LEP had significantly lower adjusted odds of adequately informed consent (AOR, 0.38; 95% CI, 0.16-0.91). A bedside interpreter phone system intervention to increase rapid access to professional interpreters was associated with improvements in patient-reported informed consent and should be considered by hospitals seeking to improve

  1. Qualitative evaluation: a critical and interpretative complementary approach to improve health programs and services. (United States)

    Tayabas, Luz María Tejada; León, Teresita Castillo; Espino, Joel Monarrez


    This short essay aims at commenting on the origin, development, rationale, and main characteristics of qualitative evaluation (QE), emphasizing the value of this methodological tool to evaluate health programs and services. During the past decades, different approaches have come to light proposing complementary alternatives to appraise the performance of public health programs, mainly focusing on the implementation process involved rather than on measuring the impact of such actions. QE is an alternative tool that can be used to illustrate and understand the process faced when executing health programs. It can also lead to useful suggestions to modify its implementation from the stakeholders' perspectives, as it uses a qualitative approach that considers participants as reflective subjects, generators of meanings. This implies that beneficiaries become involved in an active manner in the evaluated phenomena with the aim of improving the health programs or services that they receive. With this work we want to encourage evaluators in the field of public health to consider the use of QE as a complementary tool for program evaluation to be able to identify areas of opportunity to improve programs' implementation processes from the perspective of intended beneficiaries.

  2. Including crystal structure attributes in machine learning models of formation energies via Voronoi tessellations (United States)

    Ward, Logan; Liu, Ruoqian; Krishna, Amar; Hegde, Vinay I.; Agrawal, Ankit; Choudhary, Alok; Wolverton, Chris


    While high-throughput density functional theory (DFT) has become a prevalent tool for materials discovery, it is limited by the relatively large computational cost. In this paper, we explore using DFT data from high-throughput calculations to create faster, surrogate models with machine learning (ML) that can be used to guide new searches. Our method works by using decision tree models to map DFT-calculated formation enthalpies to a set of attributes consisting of two distinct types: (i) composition-dependent attributes of elemental properties (as have been used in previous ML models of DFT formation energies), combined with (ii) attributes derived from the Voronoi tessellation of the compound's crystal structure. The ML models created using this method have half the cross-validation error and similar training and evaluation speeds to models created with the Coulomb matrix and partial radial distribution function methods. For a dataset of 435 000 formation energies taken from the Open Quantum Materials Database (OQMD), our model achieves a mean absolute error of 80 meV/atom in cross validation, which is lower than the approximate error between DFT-computed and experimentally measured formation enthalpies and below 15% of the mean absolute deviation of the training set. We also demonstrate that our method can accurately estimate the formation energy of materials outside of the training set and be used to identify materials with especially large formation enthalpies. We propose that our models can be used to accelerate the discovery of new materials by identifying the most promising materials to study with DFT at little additional computational cost.

  3. 2D wireless sensor network deployment based on Centroidal Voronoi Tessellation (United States)

    Iliodromitis, Athanasios; Pantazis, George; Vescoukis, Vasileios


    In recent years, Wireless Sensor Networks (WSNs) have rapidly evolved and now comprise a powerful tool in monitoring and observation of the natural environment, among other fields. The use of WSNs is critical in early warning systems, which are of high importance today. In fact, WSNs are adopted more and more in various applications, e.g. for fire or deformation detection. The optimum deployment of sensors is a multi-dimensional problem, which has two main components; network and positioning approach. Although lots of work has dealt with the issue, most of it emphasizes on mere network approach (communication, energy consumption) and not on the topography (positioning) of the sensors in achieving ideal geometry. In some cases, it is hard or even impossible to achieve perfect geometry in nodes' deployment. The ideal and desirable scenario of nodes arranged in square or hexagonal grid would raise extremely the cost of the network, especially in unfriendly or hostile environments. In such environments the positions of the sensors have to be chosen among a list of possible points, which in most cases are randomly distributed. This constraint has to be taken under consideration during the WSN planning. Full geographical coverage is in some applications of the same, if not of greater, importance than the network coverage. Cost is a crucial factor at network planning and given that resources are often limited, what matters, is to cover the whole area with the minimum number of sensors. This paper suggests a deployment method for nodes, in large scale and high density WSNs, based on Centroidal Voronoi Tessellation (CVT). It approximates the solution through the geometry of the random points and proposes a deployment plan, for the given characteristics of the study area, in order to achieve a deployment as near as possible to the ideal one.

  4. Spurious dianeutral mixing in a global ocean model using spherical centroidal voronoi tessellations (United States)

    Zhao, Shimei; Liu, Yudi


    In order to quantitatively evaluate the spurious dianeutral mixing in a global ocean model MPAS-Ocean (Model for Prediction Across Scales) using a spherical centroidal voronoi tessellations developed jointly by the National Center for Atmospheric Research and the Los Alamos National Laboratory in the United States, we choose z* vertical coordinate system in MPAS-Ocean, in which all physical mixing processes, such as convection adjustment and explicit diffusion parameter schemes, are omitted, using a linear equation of state. By calculating the Reference Potential Energy (RPE), front revolution position, time rate of RPE change, probability density function distribution and dimensionless parameter χ, from the perspectives of resolution, viscosity, Horizontal Grid Reynolds Number (HGRN), ReΔ, and momentum transmission scheme, using two ideal cases, overflow and baroclinic eddy channel, we qualitatively analyze the simulation results by comparison with the three non-isopycnal models in Ilicak et al. (2012), i.e., MITGCM, MOM, and ROMS. The results show that the spurious dianeutral mixing in the MPAS-Ocean increases over time. The spurious dianeutral transport is proportional to the HGRN directly and is reduced by increasing the lateral viscosity or using a finer resolution to control HGRN. When the HGRN is less than 10, spurious transport is reduced significantly. When using the proper viscosity closure, MPAS-Ocean performs better than MITGCM and MOM, closely to ROMS, in the 2D case without rotation, and much better than the above-mentioned three ocean models under the condition of 3D space with rotation due to the cell area difference between the hexagon cell and the quadrilateral cell with the same resolution. Both the Zalesak (1979) flux corrected transport scheme and Leith closure in MPAS-Ocean play an excellent role in reducing spurious dianeutral mixing. The performance of Leith scheme is preferable to the condition of three-dimensional baroclinic eddy.

    Systematic reviews and meta-analyses of randomized trials that include patient-reported outcomes (PROs) often provide crucial information for patients, clinicians and policy-makers facing challenging health care decisions. Based on emerging methods, guidance on improving the interpretability of meta-analysis of patient-reported outcomes, typically continuous in nature, is likely to enhance decision-making. The objective of this paper is to summarize approaches to enhancing the interpretability of pooled estimates of PROs in meta-analyses. When differences in PROs between groups are statistically significant, decision-makers must be able to interpret the magnitude of effect. This is challenging when, as is often the case, clinical trial investigators use different measurement instruments for the same construct within and between individual randomized trials. For such cases, in addition to pooling results as a standardized mean difference, we recommend that systematic review authors use other methods to present results such as relative (relative risk, odds ratio) or absolute (risk difference) dichotomized treatment effects, complimented by presentation in either: natural units (e.g. overall depression reduced by 2.4 points when measured on a 50-point Hamilton Rating Scale for Depression); minimal important difference units (e.g. where 1.0 unit represents the smallest difference in depression that patients, on average, perceive as important the depression score was 0.38 (95% CI 0.30 to 0.47) units less than the control group); or a ratio of means (e.g. where the mean in the treatment group is divided by the mean in the control group, the ratio of means is 1.27, representing a 27% relative reduction in the mean depression score).

    Full Text Available Geopotential data may be interpreted by many different techniques, depending on the nature of the mathematical equations correlating specific unknown ground parameters to the measured data set. The investigation based on the study of the gravity and magnetic anomaly fields represents one of the most important geophysical approaches in the earth sciences. It has now evolved aimed both at improving of known methods and testing other new and reliable techniques. This paper outlines a general framework for several applications of recent techniques in the study of the potential methods for the earth sciences. Most of them are here described and significant case histories are shown to illustrate their reliability on active seismic and volcanic areas.

    To identify CT features that discriminate individuals with and without acute appendicitis in patients with equivocal CT findings, and to assess whether knowledge of these findings improves diagnostic accuracy. 53 patients that underwent appendectomy with an indeterminate preoperative CT interpretation were selected and allocated to an acute appendicitis group or a non-appendicitis group. The 53 CT examinations were reviewed by two radiologists in consensus to identify CT findings that could aid in the discrimination of those with and without appendicitis. In addition, two additional radiologists were then requested to evaluate independently the 53 CT examinations using a 4-point scale, both before and after being informed of the potentially discriminating criteria. CT findings found to be significantly different in the two groups were; the presence of appendiceal wall enhancement, intraluminal air in appendix, a coexistent inflammatory lesion, and appendiceal wall thickening (P < 0.05). Areas under the curves of reviewers 1 and 2 significantly increased from 0.516 and 0.706 to 0.677 and 0.841, respectively, when reviewers were told which CT variables were significant (P = 0.0193 and P = 0.0397, respectively). Knowledge of the identified CT findings was found to improve diagnostic accuracy for acute appendicitis in patients with equivocal CT findings. circle Numerous patients with clinically equivocal appendicitis do not have acute appendicitis circle Computed tomography (CT) helps to reduce the negative appendectomy rate circle CT is not always infallible and may also demonstrate indeterminate findings circle However knowledge of significant CT variables can further reduce negative appendectomy rate circle An equivocal CT interpretation of appendicitis should be reassessed with this knowledge.

    Living gnathostomes (jawed vertebrates) comprise two divisions, Chondrichthyes (cartilaginous fishes, including euchondrichthyans with prismatic calcified cartilage, and extinct stem chondrichthyans) and Osteichthyes (bony fishes including tetrapods). Most of the early chondrichthyan ('shark') record is based upon isolated teeth, spines, and scales, with the oldest articulated sharks that exhibit major diagnostic characters of the group--prismatic calcified cartilage and pelvic claspers in males--being from the latest Devonian, c. 360 Mya. This paucity of information about early chondrichthyan anatomy is mainly due to their lack of endoskeletal bone and consequent low preservation potential. Here we present new data from the first well-preserved chondrichthyan fossil from the early Late Devonian (ca. 380-384 Mya) Gogo Formation Lägerstatte of Western Australia. The specimen is the first Devonian shark body fossil to be acid-prepared, revealing the endoskeletal elements as three-dimensional undistorted units: Meckel's cartilages, nasal, ceratohyal, basibranchial and possible epibranchial cartilages, plus left and right scapulocoracoids, as well as teeth and scales. This unique specimen is assigned to Gogoselachus lynnbeazleyae n. gen. n. sp. The Meckel's cartilages show a jaw articulation surface dominated by an expansive cotylus, and a small mandibular knob, an unusual condition for chondrichthyans. The scapulocoracoid of the new specimen shows evidence of two pectoral fin basal articulation facets, differing from the standard condition for early gnathostomes which have either one or three articulations. The tooth structure is intermediate between the 'primitive' ctenacanthiform and symmoriiform condition, and more derived forms with a euselachian-type base. Of special interest is the highly distinctive type of calcified cartilage forming the endoskeleton, comprising multiple layers of nonprismatic subpolygonal tesserae separated by a cellular matrix, interpreted

    Energy Technology Data Exchange (ETDEWEB)

    Tomellini, Massimo, E-mail:


    On the basis of the Kolmogorov–Johnson–Mehl–Avrami (KJMA) method for space tessellation the kinetics of Voronoi cell filling, by central grain growth, has been studied as a function of the cell size. This is done by solving an integral equation for which a class of solutions is obtained in closed form, where the cell-size probability density is the Gamma distribution function. The computation gives the time evolution of the mean grain size, as a function of cell volume, which is further employed for describing the grain-size probability density function. The present approach is applied to determine, analytically, the exact grain-size distribution function in 1D and the size distributions in 2D and 3D through approximation. - Highlights: • The kinetics of cell filling is determined for Poisson–Voronoi tessellation in dD. • The kinetics is obtained in closed form by solving an integral equation. • Connection between the evolution of the mean grain and the size distribution is studied. • The exact grain-size distribution function is determined, analytically, in 1D.

  11. Experimental determination of Philodendron melinonii and Arabidopsis thaliana tissue microstructure and geometric modeling via finite-edge centroidal Voronoi tessellation (United States)

    Faisal, Tanvir R.; Hristozov, Nicolay; Rey, Alejandro D.; Western, Tamara L.; Pasini, Damiano


    Plant petioles and stems are hierarchical cellular structures, displaying structural features defined at multiple length scales. One or more of the intermediate hierarchical levels consists of tissues, in which the cellular distribution is quasirandom. The current work focuses on the realistic modeling of plant tissue microstructures. The finite-edge centroidal Voronoi tessellation (FECVT) is here introduced to overcome the drawbacks of the semi-infinite edges of a typical Voronoi model. FECVT can generate a realistic model of a tissue microstructure, which might have finite edges at its border, be defined by a boundary contour of any shape, and include complex heterogeneity and cellular gradients. The centroid-based Voronoi tessellation is applied to model the microstructure of the Philodendron melinonii petiole and the Arabidopsis thaliana stem, which both display intense cellular gradients. FECVT coupled with a digital image processing algorithm is implemented to capture the nonperiodic microstructures of plant tissues. The results obtained via this method satisfactorily obey the geometric, statistical, and topological laws of naturally evolved cellular solids. The predicted models are also validated by experimental data.

  12. Improving Clinical Information on Head CT Requisitions From the Emergency Department to Aid Interpretation and Billing Efficiency. (United States)

    Barron, Dillon; Spiegel, Thomas; Katzman, Gregory L; Haas, Kateland; Ali, Saad


    The accuracy of radiologic interpretations is higher when appropriate clinical information is provided, as is the likelihood of reimbursement for the studies. The purpose of this project was to evaluate and improve the quality of clinical information provided on head CT requisitions from an urban emergency department (ED). In a prospective study conducted from July 2015 to May 2016, attending neuroradiologists evaluated 1100 randomly selected ED requisitions for unenhanced head CT, grading them for clinical and billing adequacy on a scale of 0-2. After acquisition of baseline data (400 studies), an intervention was performed that consisted of education of ED staff on the importance of clinical information in requisitions. A reminder slide was placed on a large screen in the ED staff working area with examples of appropriate history. Postintervention data (700 studies) were subsequently obtained. Mean scores and payment lag time before versus after the intervention were compared by Wilcoxon rank sum test. Statistically significant improvement was found in mean scores after the intervention for both clinical (1.32 to 1.43, p = 0.003) and billing (1.64 to 1.74, p = 0.02) adequacy categories. The percentage of studies with a score of 2 increased in both categories, and the percentages of 0 and 1 scores declined. There was a 21.1-day decrease in payment lag time (from 75.8 to 54.7 days, p < 0.0001). The quality of clinical information provided on imaging requisitions by ED faculty and residents improved after a fairly simple intervention. Billing efficiency improved, and payment lag time decreased substantially.

  13. Could the clinical interpretability of subgroups detected using clustering methods be improved by using a novel two-stage approach? (United States)

    Kent, Peter; Stochkendahl, Mette Jensen; Christensen, Henrik Wulff; Kongsted, Alice


    Recognition of homogeneous subgroups of patients can usefully improve prediction of their outcomes and the targeting of treatment. There are a number of research approaches that have been used to recognise homogeneity in such subgroups and to test their implications. One approach is to use statistical clustering techniques, such as Cluster Analysis or Latent Class Analysis, to detect latent relationships between patient characteristics. Influential patient characteristics can come from diverse domains of health, such as pain, activity limitation, physical impairment, social role participation, psychological factors, biomarkers and imaging. However, such 'whole person' research may result in data-driven subgroups that are complex, difficult to interpret and challenging to recognise clinically. This paper describes a novel approach to applying statistical clustering techniques that may improve the clinical interpretability of derived subgroups and reduce sample size requirements. This approach involves clustering in two sequential stages. The first stage involves clustering within health domains and therefore requires creating as many clustering models as there are health domains in the available data. This first stage produces scoring patterns within each domain. The second stage involves clustering using the scoring patterns from each health domain (from the first stage) to identify subgroups across all domains. We illustrate this using chest pain data from the baseline presentation of 580 patients. The new two-stage clustering resulted in two subgroups that approximated the classic textbook descriptions of musculoskeletal chest pain and atypical angina chest pain. The traditional single-stage clustering resulted in five clusters that were also clinically recognisable but displayed less distinct differences. In this paper, a new approach to using clustering techniques to identify clinically useful subgroups of patients is suggested. Research designs, statistical

    (mean; standard deviation; confidence interval) of the ECG interpretation accuracy was (45.45%; SD=18.1%; CI=42.07, 48.83). The mean ECG interpretation accuracy rate for the IPI cohort was 58.85% (SD=42.4%; CI=49.12, 68.58), which indicates a positive mean difference of 13.4%. (CI=4.45, 22.35) An N-1 Chi-square test of independence indicated a 92% chance that the IPI cohort will have a higher accuracy rate. Interpreter self-rated confidence also increased between cohorts from a mean of 4.9/10 in the control cohort to 6.8/10 in the IPI cohort (p=0.06). Whilst the IPI cohort had greater diagnostic accuracy, the duration of ECG interpretation was six times longer when compared to the control cohort. We have developed a system that segments and presents the ECG across five graphical user interfaces. Results indicate that this approach improves diagnostic accuracy but with the expense of time, which is a valuable resource in medical practice. Copyright © 2016 Elsevier Inc. All rights reserved.

  15. Integrating population variation and protein structural analysis to improve clinical interpretation of missense variation: application to the WD40 domain. (United States)

    Laskowski, Roman A; Tyagi, Nidhi; Johnson, Diana; Joss, Shelagh; Kinning, Esther; McWilliam, Catherine; Splitt, Miranda; Thornton, Janet M; Firth, Helen V; Wright, Caroline F


    We present a generic, multidisciplinary approach for improving our understanding of novel missense variants in recently discovered disease genes exhibiting genetic heterogeneity, by combining clinical and population genetics with protein structural analysis. Using six new de novo missense diagnoses in TBL1XR1 from the Deciphering Developmental Disorders study, together with population variation data, we show that the β-propeller structure of the ubiquitous WD40 domain provides a convincing way to discriminate between pathogenic and benign variation. Children with likely pathogenic mutations in this gene have severely delayed language development, often accompanied by intellectual disability, autism, dysmorphology and gastrointestinal problems. Amino acids affected by likely pathogenic missense mutations are either crucial for the stability of the fold, forming part of a highly conserved symmetrically repeating hydrogen-bonded tetrad, or located at the top face of the β-propeller, where 'hotspot' residues affect the binding of β-catenin to the TBLR1 protein. In contrast, those altered by population variation are significantly less likely to be spatially clustered towards the top face or to be at buried or highly conserved residues. This result is useful not only for interpreting benign and pathogenic missense variants in this gene, but also in other WD40 domains, many of which are associated with disease. © The Author 2016.

    During the next decade and beyond, climate system models will be challenged to resolve scales and processes that are far beyond their current scope. Each climate system component has its prototypical example of an unresolved process that may strongly influence the global climate system, ranging from eddy activity within ocean models, to ice streams within ice sheet models, to surface hydrological processes within land system models, to cloud processes within atmosphere models. These new demands will almost certainly result in the develop of multi-resolution schemes that are able, at least regional to faithfully simulate these fine-scale processes. Spherical Centroidal Voronoi Tessellations (SCVTs) offer one potential path toward the development of robust, multi-resolution climate system component models, SCVTs allow for the generation of high quality Voronoi diagrams and Delaunay triangulations through the use of an intuitive, user-defined density function, each of the examples provided, this method results in high-quality meshes where the quality measures are guaranteed to improve as the number of nodes is increased. Real-world examples are developed for the Greenland ice sheet and the North Atlantic ocean. Idealized examples are developed for ocean-ice shelf interaction and for regional atmospheric modeling. In addition to defining, developing and exhibiting SCVTs, we pair this mesh generation technique with a previously developed finite-volume method. Our numerical example is based on the nonlinear shallow-water equations spanning the entire surface of the sphere. This example is used to elucidate both the potential benefits of this multi-resolution method and the challenges ahead.

  17. Interobserver reliability to interpret intrapartum electronic fetal heart rate monitoring: Does a standardized algorithm improve agreement among clinicians? (United States)

    Uccella, S; Cromi, A; Colombo, G F; Bogani, G; Casarin, J; Agosti, M; Ghezzi, F


    Our aim was to investigate the accuracy in predicting intrapartum fetal acidaemia and the interobserver reproducibility of a mathematical algorithm for the interpretation of electronic fetal heart rate (FHR) monitoring throughout labour. Eight physicians (blinded to the clinical outcomes of the deliveries) evaluated four randomly selected intrapartum FHR tracings by common visual interpretation, trying to predict umbilical artery base excess at birth. They subsequently were asked to re-evaluate the tracings using a mathematical algorithm for FHR tracing interpretation. Common visual interpretation allowed a correct estimation of the umbilical artery base excess in 34.4% of cases, with a poor interobserver reproducibility (Kappa correlation coefficient = 0.24). After implementation of the algorithm, the proportion of correct estimates significantly increased to 90.6% (p fetal acidaemia at birth.

  18. High-Precise Gravity Observations at Archaeological Sites: How We Can Improve the Interpretation Effectiveness and Reliability? (United States)

    Eppelbaum, Lev


    Microgravity investigations are comparatively rarely used for searching of hidden ancient targets (e.g., Eppelbaum, 2013). It is caused mainly by small geometric size of the desired archaeological objects and various types of noise complicating the observed useful signal. At the same time, development of modern generation of field gravimetric equipment allows to register microGal (10-8 m/s2) anomalies that offer a new challenge in this direction. Correspondingly, an accuracy of gravity variometers (gradientometers) is also sharply increased. How we can improve the interpretation effectiveness and reliability? Undoubtedly, it must be a multi-stage process. I believe that we must begin since nonconventional methodologies for reducing topographic effect and terrain correction computation. Topographic effect reducing The possibilities of reducing topographic effects by grouping the points of additional gravimetric observations around the central point located on the survey network were demonstrated in (Khesin et al., 1996). A group of 4 to 8 additional points is located above and below along the relief approximately symmetrically and equidistant from the central point. The topographic effect is reduced to the obtained difference between the gravity field in the center of the group and its mean value for the whole group. Application of this methodology in the gold-pyrite deposit Gyzyl-Bulakh (Lesser Caucasus, western Azerbaijan) indicated its effectiveness. Computation of terrain correction Some geophysicists compare the new ideas in the field of terrain correction (TC) in gravimetry with the 'perpetuum mobile' invention. However, when we speak about very detailed gravity observations, the problem of most optimal computation of surrounding relief influence is of a great importance. Let us will consider two approaches applied earlier in ore geophysics. First approach A first method was applied in the Gyzyl-Bulakh gold-pyrite deposit situated in the Mekhmana ore region of

    Vologzhanina, Anna V; Kats, Svitlana V; Penkova, Larisa V; Pavlenko, Vadim A; Efimov, Nikolay N; Minin, Vadim V; Eremenko, Igor L


    Interaction of 1-(1H-pyrazol-5-yl)ethanone oxime (H2PzOx) with copper(II) chloride in the presence of pyridine afforded a binuclear discrete [Cu2(HPzOx)2Cl2py2] complex, which was characterized by Fourier transform-IR and electron paramagnetic resonance (EPR) spectra, magnetochemistry and high-resolution X-ray diffraction experiments. Multipole refinement of X-ray diffraction data and density-functional theory (DFT) calculations of an isolated molecule allowed charge and spin distributions to be obtained for this compound. Magnetochemistry data, EPR spectra and DFT calculations of an isolated molecule show antiferromagnetic coupling between copper(II) ions. The spin distribution suggests an exchange pathway via the bridging pyrazole ring in the equatorial plane of the CuN4Cl coordination polyhedron, thus providing support for the classical superexchange mechanism; the calculated value of the magnetic coupling constant -2J is equal to 220 cm(-1), which compares well with the experimental value of 203 ± 2 cm(-1). Chemical connectivity was derived by Bader's 'quantum theory of atoms in molecules' and compared with Voronoi tessellation and Hirshfeld surface representations of crystal space. All methodologies gave a similar qualitative and semi-quantitative description of intra- and intermolecular connectivity.

  2. Characterization of 3D Voronoi Tessellation Nearest Neighbor Lipid Shells Provides Atomistic Lipid Disruption Profile of Protein Containing Lipid Membranes (United States)

    Cheng, Sara Y.; Duong, Hai V.; Compton, Campbell; Vaughn, Mark W.; Nguyen, Hoa; Cheng, Kwan H.


    Quantifying protein-induced lipid disruptions at the atomistic level is a challenging problem in membrane biophysics. Here we propose a novel 3D Voronoi tessellation nearest-atom-neighbor shell method to classify and characterize lipid domains into discrete concentric lipid shells surrounding membrane proteins in structurally heterogeneous lipid membranes. This method needs only the coordinates of the system and is independent of force fields and simulation conditions. As a proof-of-principle, we use this multiple lipid shell method to analyze the lipid disruption profiles of three simulated membrane systems: phosphatidylcholine, phosphatidylcholine/cholesterol, and beta-amyloid/phosphatidylcholine/cholesterol. We observed different atomic volume disruption mechanisms due to cholesterol and beta-amyloid Additionally, several lipid fractional groups and lipid-interfacial water did not converge to their control values with increasing distance or shell order from the protein. This volume divergent behavior was confirmed by bilayer thickness and chain orientational order calculations. Our method can also be used to analyze high-resolution structural experimental data.

  4. Can we improve accuracy and reliability of MRI interpretation in children with optic pathway glioma? Proposal for a reproducible imaging classification

    Magnetic resonance (MR) images from children with optic pathway glioma (OPG) are complex. We initiated this study to evaluate the accuracy of MR imaging (MRI) interpretation and to propose a simple and reproducible imaging classification for MRI. We randomly selected 140 MRIs from among 510 MRIs performed on 104 children diagnosed with OPG in France from 1990 to 2004. These images were reviewed independently by three radiologists (F.T., 15 years of experience in neuroradiology; D.L., 25 years of experience in pediatric radiology; and J.L., 3 years of experience in radiology) using a classification derived from the Dodge and modified Dodge classifications. Intra- and interobserver reliabilities were assessed using the Bland-Altman method and the kappa coefficient. These reviews allowed the definition of reliable criteria for MRI interpretation. The reviews showed intraobserver variability and large discrepancies among the three radiologists (kappa coefficient varying from 0.11 to 1). These variabilities were too large for the interpretation to be considered reproducible over time or among observers. A consensual analysis, taking into account all observed variabilities, allowed the development of a definitive interpretation protocol. Using this revised protocol, we observed consistent intra- and interobserver results (kappa coefficient varying from 0.56 to 1). The mean interobserver difference for the solid portion of the tumor with contrast enhancement was 0.8 cm{sup 3} (limits of agreement = -16 to 17). We propose simple and precise rules for improving the accuracy and reliability of MRI interpretation for children with OPG. Further studies will be necessary to investigate the possible prognostic value of this approach. (orig.)

  5. Interpretation miniatures (United States)

    Nikolić, Hrvoje

    Most physicists do not have patience for reading long and obscure interpretation arguments and disputes. Hence, to attract attention of a wider physics community, in this paper various old and new aspects of quantum interpretations are explained in a concise and simple (almost trivial) form. About the “Copenhagen” interpretation, we note that there are several different versions of it and explain how to make sense of “local nonreality” interpretation. About the many-world interpretation (MWI), we explain that it is neither local nor nonlocal, that it cannot explain the Born rule, that it suffers from the preferred basis problem, and that quantum suicide cannot be used to test it. About the Bohmian interpretation, we explain that it is analogous to dark matter, use it to explain that there is no big difference between nonlocal correlation and nonlocal causation, and use some condensed-matter ideas to outline how nonrelativistic Bohmian theory could be a theory of everything. We also explain how different interpretations can be used to demystify the delayed choice experiment, to resolve the problem of time in quantum gravity, and to provide alternatives to quantum nonlocality. Finally, we explain why is life compatible with the second law.

  6. An Innovative Open Data-driven Approach for Improved Interpretation of Coverage Data at NASA JPL's PO.DAA (United States)

    McGibbney, L. J.; Armstrong, E. M.


    Figuratively speaking, Scientific Datasets (SD) are shared by data producers in a multitude of shapes, sizes and flavors. Primarily however they exist as machine-independent manifestations supporting the creation, access, and sharing of array-oriented SD that can on occasion be spread across multiple files. Within the Earth Sciences, the most notable general examples include the HDF family, NetCDF, etc. with other formats such as GRIB being used pervasively within specific domains such as the Oceanographic, Atmospheric and Meteorological sciences. Such file formats contain Coverage Data e.g. a digital representation of some spatio-temporal phenomenon. A challenge for large data producers such as NASA and NOAA as well as consumers of coverage datasets (particularly surrounding visualization and interactive use within web clients) is that this is still not a straight-forward issue due to size, serialization and inherent complexity. Additionally existing data formats are either unsuitable for the Web (like netCDF files) or hard to interpret independently due to missing standard structures and metadata (e.g. the OPeNDAP protocol). Therefore alternative, Web friendly manifestations of such datasets are required.CoverageJSON is an emerging data format for publishing coverage data to the web in a web-friendly, way which fits in with the linked data publication paradigm hence lowering the barrier for interpretation by consumers via mobile devices and client applications, etc. as well as data producers who can build next generation Web friendly Web services around datasets. This work will detail how CoverageJSON is being evaluated at NASA JPL's PO.DAAC as an enabling data representation format for publishing SD as Linked Open Data embedded within SD landing pages as well as via semantic data repositories. We are currently evaluating how utilization of CoverageJSON within SD landing pages addresses the long-standing acknowledgement that SD producers are not currently

  7. Objective interpretation as conforming interpretation

    Directory of Open Access Journals (Sweden)

    Lidka Rodak


    Full Text Available The practical discourse willingly uses the formula of “objective interpretation”, with no regards to its controversial nature that has been discussed in literature.The main aim of the article is to investigate what “objective interpretation” could mean and how it could be understood in the practical discourse, focusing on the understanding offered by judicature.The thesis of the article is that objective interpretation, as identified with textualists’ position, is not possible to uphold, and should be rather linked with conforming interpretation. And what this actually implies is that it is not the virtue of certainty and predictability – which are usually associated with objectivity- but coherence that makes the foundation of applicability of objectivity in law.What could be observed from the analyses, is that both the phenomenon of conforming interpretation and objective interpretation play the role of arguments in the interpretive discourse, arguments that provide justification that interpretation is not arbitrary or subjective. With regards to the important part of the ideology of legal application which is the conviction that decisions should be taken on the basis of law in order to exclude arbitrariness, objective interpretation could be read as a question “what kind of authority “supports” certain interpretation”? that is almost never free of judicial creativity and judicial activism.One can say that, objective and conforming interpretation are just another arguments used in legal discourse.

  10. An Echocardiography Training Program for Improving the Left Ventricular Function Interpretation in Emergency Department; a Brief Report

    Directory of Open Access Journals (Sweden)

    Mary S. Jacob


    Full Text Available Introduction: Focused training in transthoracic echocardiography enables emergency physicians (EPs to accurately estimate the left ventricular function. This study aimed to evaluate the efficacy of a brief training program utilizing standardized echocardiography video clips in this regard. Methods: A before and after design was used to determine the efficacy of a 1 hour echocardiography training program using PowerPoint presentation and standardized echocardiography video clips illustrating normal and abnormal left ventricular ejection fraction (LVEF as well as video clips emphasizing the measurement of mitral valve E-point septal separation (EPSS. Pre- and post-test evaluation used unique video clips and asked trainees to estimate LVEF and EPSS based on the viewed video clips. Results: 21 EPs with no prior experience with the echocardiographic technical methods completed this study. The EPs had very limited prior echocardiographic training. The mean score on the categorization of LVEF estimation improved from 4.9 (95% CI: 4.1-5.6 to 7.6 (95%CI: 7-8.3 out of a possible 10 score (p<0.0001. Categorization of EPSS improved from 4.1 (95% CI: 3.1-5.1 to 8.1 (95% CI: 7.6- 8.7 after education (p<0.0001. Conclusions: The results of this study demonstrate a statistically significant improvement of EPs’ ability to categorize left ventricular function as normal or depressed, after a short lecture utilizing a commercially available DVD of standardized echocardiography clips.

  11. Penultimate interpretation. (United States)

    Neuman, Yair


    Interpretation is at the center of psychoanalytic activity. However, interpretation is always challenged by that which is beyond our grasp, the 'dark matter' of our mind, what Bion describes as ' O'. O is one of the most central and difficult concepts in Bion's thought. In this paper, I explain the enigmatic nature of O as a high-dimensional mental space and point to the price one should pay for substituting the pre-symbolic lexicon of the emotion-laden and high-dimensional unconscious for a low-dimensional symbolic representation. This price is reification--objectifying lived experience and draining it of vitality and complexity. In order to address the difficulty of approaching O through symbolization, I introduce the term 'Penultimate Interpretation'--a form of interpretation that seeks 'loopholes' through which the analyst and the analysand may reciprocally save themselves from the curse of reification. Three guidelines for 'Penultimate Interpretation' are proposed and illustrated through an imaginary dialogue. Copyright © 2010 Institute of Psychoanalysis.

  12. Quantum interpretations

    Energy Technology Data Exchange (ETDEWEB)

    Goernitz, T.; Weizsaecker, C.F.V.


    Four interpretations of quantum theory are compared: the Copenhagen interpretation (C.I.) with the additional assumption that the quantum description also applies to the mental states of the observer, and three recent ones, by Kochen, Deutsch, and Cramer. Since they interpret the same mathematical structure with the same empirical predictions, it is assumed that they formulate only different linguistic expressions of one identical theory. C.I. as a theory on human knowledge rests on a phenomenological description of time. It can be reconstructed from simple assumptions on predictions. Kochen shows that mathematically every composite system can be split into an object and an observer. Deutsch, with the same decomposition, describes futuric possibilities under the Everett term worlds. Cramer, using four-dimensional action at a distance (Wheeler-Feynman), describes all future events like past facts. All three can be described in the C.I. frame. The role of abstract nonlocality is discussed.

  13. Interpreting Physics

    CERN Document Server

    MacKinnon, Edward


    This book is the first to offer a systematic account of the role of language in the development and interpretation of physics. An historical-conceptual analysis of the co-evolution of mathematical and physical concepts leads to the classical/quatum interface. Bohrian orthodoxy stresses the indispensability of classical concepts and the functional role of mathematics. This book analyses ways of extending, and then going beyond this orthodoxy orthodoxy. Finally, the book analyzes how a revised interpretation of physics impacts on basic philosophical issues: conceptual revolutions, realism, and r

  14. Using in-situ Glider Data to Improve the Interpretation of Time-Series Data in the San Pedro Channel (United States)

    Teel, E.; Liu, X.; Seegers, B. N.; Ragan, M. A.; Jones, B. H.; Levine, N. M.


    Oceanic time-series have provided insight into biological, physical, and chemical processes and how these processes change over time. However, time-series data collected near coastal zones have not been used as broadly because of regional features that may prevent extrapolation of local results. Though these sites are inherently more affected by local processes, broadening the application of coastal data is crucial for improved modeling of processes such as total carbon drawdown and the development of oxygen minimum zones. Slocum gliders were deployed off the coast of Los Angeles from February to July of 2013 and 2014 providing high temporal and spatial resolution data of the San Pedro Channel (SPC), which includes the San Pedro Ocean Time Series (SPOT). The data were collapsed onto a standardized grid and primary and secondary characteristics of glider profiles were analyzed by principal component analysis to determine the processes impacting SPC and SPOT. The data fell into four categories: active upwelling, offshore intrusion, subsurface bloom, and surface bloom. Waters across the SPC were most similar to offshore water masses, even during the upwelling season when near-shore blooms are commonly observed. The SPOT site was found to be representative of the SPC 86% of the time, suggesting that the findings from SPOT are applicable for the entire SPC. Subsurface blooms were common in both years with co-located chlorophyll and particle maxima, and results suggested that these subsurface blooms contribute significantly to the local primary production. Satellite estimation of integrated chlorophyll was poor, possibly due to the prevalence of subsurface blooms and shallow optical depths during surface blooms. These results indicate that high resolution in-situ glider deployments can be used to determine the spatial domain of coastal time-series data, allowing for broader application of these datasets and greater integration into modeling efforts.

  15. Interpretive Error in Radiology. (United States)

    Waite, Stephen; Scott, Jinel; Gale, Brian; Fuchs, Travis; Kolla, Srinivas; Reede, Deborah


    Although imaging technology has advanced significantly since the work of Garland in 1949, interpretive error rates remain unchanged. In addition to patient harm, interpretive errors are a major cause of litigation and distress to radiologists. In this article, we discuss the mechanics involved in searching an image, categorize omission errors, and discuss factors influencing diagnostic accuracy. Potential individual- and system-based solutions to mitigate or eliminate errors are also discussed. Radiologists use visual detection, pattern recognition, memory, and cognitive reasoning to synthesize final interpretations of radiologic studies. This synthesis is performed in an environment in which there are numerous extrinsic distractors, increasing workloads and fatigue. Given the ultimately human task of perception, some degree of error is likely inevitable even with experienced observers. However, an understanding of the causes of interpretive errors can help in the development of tools to mitigate errors and improve patient safety.

  18. Modified MODIS fluorescence line height data product to improve image interpretation for red tide monitoring in the eastern Gulf of Mexico (United States)

    Hu, Chuanmin; Feng, Lian


    Several satellite-based methods have been used to detect and trace Karenia brevis red tide blooms in the eastern Gulf of Mexico. Some require data statistics and multiple data products while others use a single data product. Of these, the MODIS normalized fluorescence line height (nFLH) has shown its advantage of detecting blooms in waters rich in colored dissolved organic matter, thus having been used routinely to assess bloom conditions by the Florida Fish and Wildlife Conservation Commission (FWC), the official state agency of Florida responsible for red tide monitoring and mitigation. However, elevated sediment concentrations in the water column due to wind storms can also result in high nFLH values, leading to false-positive bloom interpretation. Here, a modified nFLH data product is developed to minimize such impacts through empirical adjustments of the nFLH values using MODIS-derived remote sensing reflectance in the green band at 547 nm. The new product is termed as an algal bloom index (ABI), which has shown improved performance over the original nFLH in both retrospective evaluation statistics and near real-time applications. The ABI product has been made available in near real-time through a Web portal and has been used by the FWC on a routine basis to guide field sampling efforts and prepare for red tide bulletins distributed to many user groups.

  19. Conducting psychotherapy with an interpreter. (United States)

    Kuay, Justin; Chopra, Prem; Kaplan, Ida; Szwarc, Josef


    This qualitative study assessed how clinicians prepared and used interpreters during psychotherapeutic sessions and investigated the strategies they used to manage the dynamics of this process. Ten therapists were interviewed at the Victorian Foundation for the Survivors of Torture (VFST). A semi-structured interview format was used. Thematic analysis was conducted on transcripts of recorded interviews to identify key themes. Factors affecting the provision of psychotherapy with interpreters agreed with general guidelines for working with interpreters but there were exceptions. The possible roles of the interpreter as a cultural consultant, community advocate and co-therapist were explored. Specific troubleshooting strategies were identified for improving empathy, redefining roles, and adjusting interactions with interpreters. Working with interpreters in psychotherapy is a complex process. These findings may benefit clinicians providing psychotherapy to patients using interpreters. © The Royal Australian and New Zealand College of Psychiatrists 2015.

  20. Impact of an easy-access telephonic interpreter program in the acute care setting: an evaluation of a quality improvement intervention. (United States)

    Tuot, Delphine S; Lopez, Monica; Miller, Cecily; Karliner, Leah S


    Language barriers render interaction with the health care system difficult and lead to health disparities for patients with limited English proficiency (LEP). Despite a long-standing legal obligation for large health care organizations in the United States to try to provide free language access services for patients with LEP, professional interpretation is not always widely accessible, and even when it is, its use is often suboptimal. A dual-handset phone with 24-hour access to professional telephonic interpretation was placed at the bedside of all patients admitted to the general medicine floor of a tertiary care academic hospital. Nurses and physicians were surveyed before and after the easy-access interpretation program's implementation. Distribution of pre- and postimplementation surveys to 127 and 122 nurses, respectively, yielded a total of 163 completed surveys (overall participation rate, 65%). Distribution of surveys to 96 and 78 physicians, respectively, yielded 116 completed surveys (overall participation rate, 67%). After implementation, use of professional telephonic interpreters for communication with LEP patients increased fourfold, without a decrease in use of professional in-person interpreters. There were significant increases in professional interpreter use during brief communications with high error potential, including medication administration (odds ratio [OR] = 1.9, 95% confidence interval [CI] 1.1-3.2) and pre-rounding (OR = 3.4, 95% CI 1.2-9.8). Increasing ease of access to dual-handset interpreter telephones promotes use of professional interpreters in the acute care setting. Future hospital policy should focus on further integrating language services into the hospital environment, accompanied by an educational program to assist in shifting professional norms toward use of professional interpreters.

  1. Environment characterization as an aid to wheat improvement: interpreting genotype-environment interactions by modelling water-deficit patterns in North-Eastern Australia. (United States)

    Chenu, K; Cooper, M; Hammer, G L; Mathews, K L; Dreccer, M F; Chapman, S C


    Genotype-environment interactions (GEI) limit genetic gain for complex traits such as tolerance to drought. Characterization of the crop environment is an important step in understanding GEI. A modelling approach is proposed here to characterize broadly (large geographic area, long-term period) and locally (field experiment) drought-related environmental stresses, which enables breeders to analyse their experimental trials with regard to the broad population of environments that they target. Water-deficit patterns experienced by wheat crops were determined for drought-prone north-eastern Australia, using the APSIM crop model to account for the interactions of crops with their environment (e.g. feedback of plant growth on water depletion). Simulations based on more than 100 years of historical climate data were conducted for representative locations, soils, and management systems, for a check cultivar, Hartog. The three main environment types identified differed in their patterns of simulated water stress around flowering and during grain-filling. Over the entire region, the terminal drought-stress pattern was most common (50% of production environments) followed by a flowering stress (24%), although the frequencies of occurrence of the three types varied greatly across regions, years, and management. This environment classification was applied to 16 trials relevant to late stages testing of a breeding programme. The incorporation of the independently-determined environment types in a statistical analysis assisted interpretation of the GEI for yield among the 18 representative genotypes by reducing the relative effect of GEI compared with genotypic variance, and helped to identify opportunities to improve breeding and germplasm-testing strategies for this region.

  2. Improving interpretation of geoelectrical signatures arising from biomineralization process in porous media: Low-frequency dielectric spectroscopy measurements on Desulfovibrio vulgaris cell suspensions (United States)

    Zhang, C.; Prodan, C.; Slater, L. D.; Bot, C.; Ntarlagiannis, D.


    Previous geophysical studies have demonstrated the sensitivity of complex conductivity measurements to microbial growth, biofilm formation, and microbial-mineral alternations, indicating that complex conductivity has the potential to serve as non-invasive tool for bioremediation monitoring. However, the inherent dielectric properties of microbes and how they might directly contribute to the geophysical responses observed during microbial-mineral transformations are not well understood. As a first step towards improving the understanding of electrical signals from microbial-mineral transformations in porous media, we studied the low frequency dielectric properties of sulfate-reducing bacteria (Desulfovibrio vulgaris) cell suspensions, a common soil borne microorganism involved in remediation of toxic metals in solution. We utilized a two-electrode dielectric spectroscopy measurement, common in biophysics applications,to acquire high quality dielectric dispersion curves of Desulfovibrio vulgaris cell suspensions over the frequency range 0.1 Hz to 1M Hz. Desulfovibrio vulgaris cell suspensions were placed between two parallel steel electrodes that are enclosed in a cylindrical glass tube, and the complex impedance of sample was measured relative to a known resistor. The measured impedance includes an electrode polarization impedance arising at the interface between electrodes and ionic solutions at low frequencies. This electrode impedance has traditionally precluded the reliable interpretation of two electrode techniques at low frequencies (< 1000 Hz). In order to obtain the true dielectric dispersion curve of sample, we adopt a simple and robust strategy to measure, analyze and remove the polarization impedance. The feasibility of this polarization removal technique was tested on water saturated glass beads. We show that the broadband dielectric response of Desulfovibrio vulgaris can be reliably determined with this approach. The measurements are modeled based on a

    For the study of minerals and semiprecious stones, such as turquoise, it is necessary to use a combined analysis in order to determine crystalline minerals phases and elemental com- position. In this way, it is possible to identify mineralogical substitutions in the crystals and to perform sourcing by trace elemental analysis. In this work, the analysis focused on the study of surface alterations of tessels from a disc found in the 99 offering from Templo Mayor of Tenochtitlan. Rutherford Backscattering Spectrometry and Particle Induced X-ray Emission (PIXE) Spectrometries using protons and alpha particles were applied to determine surface elemental analysis of tessels of different colours (blue, green, white). For mineralogical identification, standard X-ray Diffraction was used. (Author)

  5. Weak-Lensing Calibration of a Stellar Mass-Based Mass Proxy for redMaPPer and Voronoi Tessellation Clusters in SDSS Stripe 82

    Pereira, Maria E.S. [Rio de Janeiro, CBPF; Soares-Santos, Marcelle [Fermilab; Makler, Martin [Rio de Janeiro, CBPF; Annis, James [Fermilab; Lin, Huan [Fermilab; Palmese, Antonella [Fermilab; Vitorelli, André Z. [Sao Paulo, Inst. Astron. Geofis.; Welch, Brian [Fermilab; Caminha, Gabriel B. [Bologna Observ.; Erben, Thomas [Argelander Inst. Astron.; Moraes, Bruno [University Coll. London; Shan, Huanyuan [Argelander Inst. Astron.


    We present the first weak lensing calibration of $\\mu_{\\star}$, a new galaxy cluster mass proxy corresponding to the total stellar mass of red and blue members, in two cluster samples selected from the SDSS Stripe 82 data: 230 redMaPPer clusters at redshift $0.1\\leq z<0.33$ and 136 Voronoi Tessellation (VT) clusters at $0.1 \\leq z < 0.6$. We use the CS82 shear catalog and stack the clusters in $\\mu_{\\star}$ bins to measure a mass-observable power law relation. For redMaPPer clusters we obtain $M_0 = (1.77 \\pm 0.36) \\times 10^{14}h^{-1} M_{\\odot}$, $\\alpha = 1.74 \\pm 0.62$. For VT clusters, we find $M_0 = (4.31 \\pm 0.89) \\times 10^{14}h^{-1} M_{\\odot}$, $\\alpha = 0.59 \\pm 0.54$ and $M_0 = (3.67 \\pm 0.56) \\times 10^{14}h^{-1} M_{\\odot}$, $\\alpha = 0.68 \\pm 0.49$ for a low and a high redshift bin, respectively. Our results are consistent, internally and with the literature, indicating that our method can be applied to any cluster finding algorithm. In particular, we recommend that $\\mu_{\\star}$ be used as the mass proxy for VT clusters. Catalogs including $\\mu_{\\star}$ measurements will enable its use in studies of galaxy evolution in clusters and cluster cosmology.

  7. [Effect of using an interpreter in psychotherapy]. (United States)

    Jensen, Rikke Sander; Nørregaard, Trine Maria; Carlsson, Jessica


    An evaluation of the effect of using an interpreter in psychotherapy is quite complex. In the few existing studies on the use of interpreters in psychotherapy no significant difference was found in treatment outcome related to whether an interpreter was used or not. On the other hand, the inclusion of an interpreter affects the therapeutic alliance and the relationships between the parties. The role of the interpreter in psychotherapy is characterized by diversity, and the included studies indicate the need for training to improve the cooperation between the interpreter and the therapist.

    Full Text Available Time has proved that Economic Analysis is not enough as to ensure all the needs of the economic field. The present study wishes to propose a new approach method of the economic phenomena and processes based on the researches made outside the economic space- a new general interpretation theory- which is centered on the human being as the basic actor of economy. A general interpretation theory must assure the interpretation of the causalities among the economic phenomena and processes- causal interpretation; the interpretation of the correlations and dependencies among indicators- normative interpretation; the interpretation of social and communicational processes in economic organizations- social and communicational interpretation; the interpretation of the community status of companies- transsocial interpretation; the interpretation of the purposes of human activities and their coherency – teleological interpretation; the interpretation of equilibrium/ disequilibrium from inside the economic systems- optimality interpretation. In order to respond to such demands, rigor, pragmatism, praxiology and contextual connectors are required. In order to progress, the economic science must improve its language, both its syntax and its semantics. The clarity of exposure requires a language clarity and the scientific theory progress asks for the need of hypotheses in the building of the theories. The switch from the common language to the symbolic one means the switch from ambiguity to rigor and rationality, that is order in thinking. But order implies structure, which implies formalization. Our paper should be a plea for these requirements, requirements which should be fulfilled by a modern interpretation theory.

  9. Interpretative reports and critical values. (United States)

    Piva, Elisa; Plebani, Mario


    In the clinical laboratory to allow an effective testing process, post-analytical activity can have two goals in trying to improve patient safety: result interpretation and communication of critical values. Both are important issues, and their success requires a cooperative effort. Misinterpretation of laboratory test results or ineffectiveness in their notification can lead to diagnostic errors or errors in identifying patient critical conditions. With the awareness that the incorrect interpretation of tests and the breakdown in the communication of critical values are preventable errors, laboratorians should make every effort to prevent the types of errors that potentially harm patients. In order to improve the reliability of laboratories, we attempt to explain how interpretative reporting and automated notification of critical values can be used to reduce errors. Clinical laboratories can therefore work to improve clinical effectiveness, without forgetting that everything should be designed to provide the best outcomes for patients.

  11. Interpreting Impoliteness: Interpreters’ Voices

    Directory of Open Access Journals (Sweden)

    Tatjana Radanović Felberg


    Full Text Available Interpreters in the public sector in Norway interpret in a variety of institutional encounters, and the interpreters evaluate the majority of these encounters as polite. However, some encounters are evaluated as impolite, and they pose challenges when it comes to interpreting impoliteness. This issue raises the question of whether interpreters should take a stance on their own evaluation of impoliteness and whether they should interfere in communication. In order to find out more about how interpreters cope with this challenge, in 2014 a survey was sent to all interpreters registered in the Norwegian Register of Interpreters. The survey data were analyzed within the theoretical framework of impoliteness theory using the notion of moral order as an explanatory tool in a close reading of interpreters’ answers. The analysis shows that interpreters reported using a variety of strategies for interpreting impoliteness, including omissions and downtoning. However, the interpreters also gave examples of individual strategies for coping with impoliteness, such as interrupting and postponing interpreting. These strategies border behavioral strategies and conflict with the Norwegian ethical guidelines for interpreting. In light of the ethical guidelines and actual practice, mapping and discussing different strategies used by interpreters might heighten interpreters’ and interpreter-users’ awareness of the role impoliteness can play in institutional interpreter– mediated encounters. 

  12. Dialectica Interpretation with Marked Counterexamples

    Directory of Open Access Journals (Sweden)

    Trifon Trifonov


    Full Text Available Goedel's functional "Dialectica" interpretation can be used to extract functional programs from non-constructive proofs in arithmetic by employing two sorts of higher-order witnessing terms: positive realisers and negative counterexamples. In the original interpretation decidability of atoms is required to compute the correct counterexample from a set of candidates. When combined with recursion, this choice needs to be made for every step in the extracted program, however, in some special cases the decision on negative witnesses can be calculated only once. We present a variant of the interpretation in which the time complexity of extracted programs can be improved by marking the chosen witness and thus avoiding recomputation. The achieved effect is similar to using an abortive control operator to interpret computational content of non-constructive principles.

  13. Physical interpretation of antigravity (United States)

    Bars, Itzhak; James, Albin


    Geodesic incompleteness is a problem in both general relativity and string theory. The Weyl-invariant Standard Model coupled to general relativity (SM +GR ), and a similar treatment of string theory, are improved theories that are geodesically complete. A notable prediction of this approach is that there must be antigravity regions of spacetime connected to gravity regions through gravitational singularities such as those that occur in black holes and cosmological bang/crunch. Antigravity regions introduce apparent problems of ghosts that raise several questions of physical interpretation. It was shown that unitarity is not violated, but there may be an instability associated with negative kinetic energies in the antigravity regions. In this paper we show that the apparent problems can be resolved with the interpretation of the theory from the perspective of observers strictly in the gravity region. Such observers cannot experience the negative kinetic energy in antigravity directly, but can only detect in and out signals that interact with the antigravity region. This is no different from a spacetime black box for which the information about its interior is encoded in scattering amplitudes for in/out states at its exterior. Through examples we show that negative kinetic energy in antigravity presents no problems of principles but is an interesting topic for physical investigations of fundamental significance.

  14. Adaptation of a probabilistic method (InterVA of verbal autopsy to improve the interpretation of cause of stillbirth and neonatal death in Malawi, Nepal, and Zimbabwe

    Directory of Open Access Journals (Sweden)

    Munjanja Stephan P


    Full Text Available Abstract Background Verbal autopsy (VA is a widely used method for analyzing cause of death in absence of vital registration systems. We adapted the InterVA method to extrapolate causes of death for stillbirths and neonatal deaths from verbal autopsy questionnaires, using data from Malawi, Zimbabwe, and Nepal. Methods We obtained 734 stillbirth and neonatal VAs from recent community studies in rural areas: 169 from Malawi, 385 from Nepal, and 180 from Zimbabwe. Initial refinement of the InterVA model was based on 100 physician-reviewed VAs from Malawi. InterVA indicators and matrix probabilities for cause of death were reviewed for clinical and epidemiological coherence by a pediatrician-researcher and an epidemiologist involved in the development of InterVA. The modified InterVA model was evaluated by comparing population-level cause-specific mortality fractions and individual agreement from two methods of interpretation (physician review and InterVA for a further 69 VAs from Malawi, 385 from Nepal, and 180 from Zimbabwe. Results Case-by-case agreement between InterVA and reviewing physician diagnoses for 69 cases from Malawi, 180 cases from Zimbabwe, and 385 cases from Nepal were 83% (kappa 0.76 (0.75 - 0.80, 71% (kappa 0.41(0.32-0.51, and 74% (kappa 0.63 (0.60-0.63, respectively. The proportion of stillbirths identified as fresh or macerated by the different methods of VA interpretation was similar in all three settings. Comparing across countries, the modified InterVA method found that proportions of preterm births and deaths due to infection were higher in Zimbabwe (44% than in Malawi (28% or Nepal (20%. Conclusion The modified InterVA method provides plausible results for stillbirths and newborn deaths, broadly comparable to physician review but with the advantage of internal consistency. The method allows standardized cross-country comparisons and eliminates the inconsistencies of physician review in such comparisons.

  15. A high-enrollment course-based undergraduate research experience improves student conceptions of scientific thinking and ability to interpret data. (United States)

    Brownell, Sara E; Hekmat-Scafe, Daria S; Singla, Veena; Chandler Seawell, Patricia; Conklin Imam, Jamie F; Eddy, Sarah L; Stearns, Tim; Cyert, Martha S


    We present an innovative course-based undergraduate research experience curriculum focused on the characterization of single point mutations in p53, a tumor suppressor gene that is mutated in more than 50% of human cancers. This course is required of all introductory biology students, so all biology majors engage in a research project as part of their training. Using a set of open-ended written prompts, we found that the course shifts student conceptions of what it means to think like a scientist from novice to more expert-like. Students at the end of the course identified experimental repetition, data analysis, and collaboration as important elements of thinking like a scientist. Course exams revealed that students showed gains in their ability to analyze and interpret data. These data indicate that this course-embedded research experience has a positive impact on the development of students' conceptions and practice of scientific thinking. © 2015 S. E. Brownell et al.

  16. Can horizontally oriented breast tomosynthesis image volumes or the use of a systematic search strategy improve interpretation? An eye tracking and free response human observer study (United States)

    Lång, Kristina; Zackrisson, Sophia; Holmqvist, Kenneth; Nyström, Marcus; Andersson, Ingvar; Förnvik, Daniel; Tingberg, Anders; Timberg, Pontus


    Our aim was to evaluate if there is a benefit in diagnostic accuracy and efficiency of viewing breast tomosynthesis (BT) image volumes presented horizontally oriented, but also to evaluate the use of a systematic search strategy where the breast is divided, and analyzed consecutively, into two sections. These image presentations were compared to regular vertical image presentation. All methods were investigated using viewing procedures consisting of free scroll volume browsing, and a combination of initial cine loops at three different frame rates (9, 14, 25 fps) terminated upon request followed by free scroll volume browsing if needed. Fifty-five normal BT image volumes in MLO view were collected. In these, simulated lesions (20 masses and 20 clusters of microcalcifications) were randomly inserted, creating four unique image sets for each procedure. Four readers interpreted the cases in a random order. Their task was to locate the lesions, mark and assign a five level confidence scale. The diagnostic accuracy was analyzed using Jackknife Free Receiver Operating Characteristics (JAFROC). Time efficiency and visual search behavior were also investigated using eye tracking. Results indicate there was no statistically significant difference in JAFROC FOM between the different image presentations, although visual search was more time efficient when viewing horizontally oriented image volumes in medium cine loops.

    Lean, Ian J; Lucy, Matthew C; McNamara, John P; Bradford, Barry J; Block, Elliot; Thomson, Jennifer M; Morton, John M; Celi, Pietro; Rabiee, Ahmad R; Santos, José E P; Thatcher, William W; LeBlanc, Stephen J


    Abundant evidence from the medical, veterinary, and animal science literature demonstrates that there is substantial room for improvement of the clarity, completeness, and accuracy of reporting of intervention studies. More rigorous reporting guidelines are needed to improve the quality of data available for use in comparisons of outcomes (or meta-analyses) of multiple studies. Because of the diversity of factors that affect reproduction and the complexity of interactions between these, a systematic approach is required to design, conduct, and analyze basic and applied studies of dairy cattle reproduction. Greater consistency, clarity, completeness, and correctness of design and reporting will improve the value of each report and allow for greater depth of evaluation in meta-analyses. Each of these benefits will improve understanding and application of current knowledge and better identify questions that require additional modeling or primary research. The proposed guidelines and checklist will aid in the design, conduct, analysis, and reporting of intervention studies. We propose an adaptation of the REFLECT (Reporting Guidelines for Randomized Controlled Trials for Livestock and Food Safety) statement to provide guidelines and a checklist specific to reporting intervention studies in dairy cattle reproduction. Furthermore, we provide recommendations that will assist investigators to produce studies with greater internal and external validity that can more often be included in systematic reviews and global meta-analyses. Such studies will also assist the development of models to describe the physiology of reproduction. Copyright © 2016 American Dairy Science Association. Published by Elsevier Inc.

    Shifting X-ray interpretation to non-radiologists can help to address radiologist shortages in developing countries. To determine the change in accuracy of non-radiologists and radiologists for the radiographic diagnosis of paediatric tuberculosis after a short skill-development course. Participants interpreted 15 paediatric chest radiographs before and after a 30-minute course using three possible responses: (1) diagnostic for tuberculosis, (2) abnormal but inconclusive for diagnosis of tuberculosis and (3) normal. We compared proportions of correct diagnoses, sensitivity, and specificity, before and after the course. We included 256 participants comprising 229 non-radiologists (134 radiographers, 32 paediatricians, 39 Medecins Sans Frontieres clinicians and 24 physicians including paediatricians) and 27 radiologists. Mean change proportions of correct diagnosis ranged from -27% to 53% for individuals and 9% to 20% for groups. All groups showed a statistically significant improvement. Mean change in diagnostic sensitivity ranged from -38% to 100% for individuals and from 16% to 41% for groups. All groups showed a statistically significant improvement. Mean change in specificity ranged from -57% to 57% for individuals and from -15% to -4% for groups. The decrease was statistically significant for physicians, paediatricians and radiographers. The course resulted in increased correct diagnoses and improved sensitivity at the expense of specificity. (orig.)

  19. A description of the demographic characteristics of the New Zealand non-commercial horse population with data collected using a generalised random-tessellation stratified sampling design. (United States)

    Rosanowski, S M; Cogger, N; Rogers, C W; Benschop, J; Stevenson, M A


    We conducted a cross-sectional survey to determine the demographic characteristics of non-commercial horses in New Zealand. A sampling frame of properties with non-commercial horses was derived from the national farms database, AgriBase™. Horse properties were stratified by property size and a generalised random-tessellated stratified (GRTS) sampling strategy was used to select properties (n=2912) to take part in the survey. The GRTS sampling design allowed for the selection of properties that were spatially balanced relative to the distribution of horse properties throughout the country. The registered decision maker of the property, as identified in AgriBase™, was sent a questionnaire asking them to describe the demographic characteristics of horses on the property, including the number and reason for keeping horses, as well as information about other animals kept on the property and the proximity of boundary neighbours with horses. The response rate to the survey was 38% (1044/2912) and the response rate was not associated with property size or region. A total of 5322 horses were kept for recreation, competition, racing, breeding, stock work, or as pets. The reasons for keeping horses and the number and class of horses varied significantly between regions and by property size. Of the properties sampled, less than half kept horses that could have been registered with Equestrian Sports New Zealand or either of the racing codes. Of the respondents that reported knowing whether their neighbours had horses, 58.6% (455/776) of properties had at least one boundary neighbour that kept horses. The results of this study have important implications for New Zealand, which has an equine population that is naïve to many equine diseases considered endemic worldwide. The ability to identify, and apply accurate knowledge of the population at risk to infectious disease control strategies would lead to more effective strategies to control and prevent disease spread during an

  2. The reaction of safrole derivatives with aluminum chloride: improved procedures for the preparation of catechols or their mono-O-Methylated Derivatives and a mechanistic interpretation

    Directory of Open Access Journals (Sweden)

    Amorim Mauro B. de


    Full Text Available An improved procedure for the "one-pot" preparation of cathecols from methylenedioxy-ring cleavage reaction of safrole derivatives with aluminum chloride is described. In substrates substituted by conjugated electron-withdrawing groups (carboxyaldehyde or nitro groups the regioselective formation of the easily isolable chloromethyl ether intermediates was observed. From these intermediates the syntheses of mono-O-methylated phenols (3-hydroxy-4-methoxybenzaldehyde, 2-bromo-4-methoxy-5-hydroxybenzaldehyde, 2-nitro-4-methoxy-5-hydroxybenzaldehyde and 2-methoxy-4-(2-oxoprop-1-yl-5-nitrophenol were accomplished. Based on these experimental data and semi-empirical (MNDO molecular orbital calculations, a mechanistic rationale that explains the observed regioselectivities was also proposed.

  3. Coupling gene-based and classic veterinary diagnostics improves interpretation of health and immune function in the Agassiz’s desert tortoise (Gopherus agassizii) (United States)

    Drake, Karla K.; Bowen, Lizabeth; Lewison, Rebecca L.; Esque, Todd C.; Nussear, Kenneth E.; Braun, Josephine; Waters, Shannon C.; Miles, A. Keith


    The analysis of blood constituents is a widely used tool to aid in monitoring of animal health and disease. However, classic blood diagnostics (i.e. hematologic and plasma biochemical values) often do not provide sufficient information to determine the state of an animal’s health. Field studies on wild tortoises and other reptiles have had limited success in drawing significant inferences between blood diagnostics and physiological and immunological condition. However, recent research using gene transcription profiling in the threatened Mojave desert tortoise (Gopherus agassizii) has proved useful in identifying immune or physiologic responses and overall health. To improve our understanding of health and immune function in tortoises, we evaluated both standard blood diagnostic (body condition, hematologic, plasma biochemistry values, trace elements, plasma proteins, vitamin A levels) and gene transcription profiles in 21 adult tortoises (11 clinically abnormal; 10 clinically normal) from Clark County, NV, USA. Necropsy and histology evaluations from clinically abnormal tortoises revealed multiple physiological complications, with moderate to severe rhinitis or pneumonia being the primary cause of morbidity in all but one of the examined animals. Clinically abnormal tortoises had increased transcription for four genes (SOD, MyD88, CL and Lep), increased lymphocyte production, biochemical enzymes and organics, trace elements of copper, and decreased numbers of leukocytes. We found significant positive correlations between increased transcription for SOD and increased trace elements for copper, as well as genes MyD88 and Lep with increased inflammation and microbial insults. Improved methods for health assessments are an important element of monitoring tortoise population recovery and can support the development of more robust diagnostic measures for ill animals, or individuals directly impacted by disturbance.

  4. Interpretation biases in paranoia. (United States)

    Savulich, George; Freeman, Daniel; Shergill, Sukhi; Yiend, Jenny


    Information in the environment is frequently ambiguous in meaning. Emotional ambiguity, such as the stare of a stranger, or the scream of a child, encompasses possible good or bad emotional consequences. Those with elevated vulnerability to affective disorders tend to interpret such material more negatively than those without, a phenomenon known as "negative interpretation bias." In this study we examined the relationship between vulnerability to psychosis, measured by trait paranoia, and interpretation bias. One set of material permitted broadly positive/negative (valenced) interpretations, while another allowed more or less paranoid interpretations, allowing us to also investigate the content specificity of interpretation biases associated with paranoia. Regression analyses (n=70) revealed that trait paranoia, trait anxiety, and cognitive inflexibility predicted paranoid interpretation bias, whereas trait anxiety and cognitive inflexibility predicted negative interpretation bias. In a group comparison those with high levels of trait paranoia were negatively biased in their interpretations of ambiguous information relative to those with low trait paranoia, and this effect was most pronounced for material directly related to paranoid concerns. Together these data suggest that a negative interpretation bias occurs in those with elevated vulnerability to paranoia, and that this bias may be strongest for material matching paranoid beliefs. We conclude that content-specific biases may be important in the cause and maintenance of paranoid symptoms. Copyright © 2014. Published by Elsevier Ltd.

  5. Determining high-quality critical body residues for multiple species and chemicals by applying improved experimental design and data interpretation concepts. (United States)

    van der Heijden, Stephan A; Hermens, Joop L M; Sinnige, Theo L; Mayer, Philipp; Gilbert, Dorothea; Jonker, Michiel T O


    Ecotoxicological effect data are generally expressed as effective concentrations in the external exposure medium and do thus not account for differences in chemical uptake, bioavailability, and metabolism, which can introduce substantial data variation. The Critical Body Residue (CBR) concept provides clear advantages, because it links effects directly to the internal exposure. Using CBRs instead of external concentrations should therefore reduce variability. For compounds that act via narcosis even a constant CBR has been proposed. Despite the expected uniformity, CBR values for these compounds still show large variability, possibly due to biased and inconsistent experimental testing. In the present study we tested whether variation in CBR data can be substantially reduced when using an improved experimental design and avoiding confounding factors. The aim was to develop and apply a well-defined test protocol for accurately and precisely measuring CBR data, involving improved (passive) dosing, sampling, and processing of organisms. The chemicals 1,2,4-trichlorobenzene, 1,2,3,4-tetrachlorobenzene, 2,3,4-trichloroaniline, 2,3,5,6-tetrachloroaniline, 4-chloro-3-methylphenol, pentylbenzene, pyrene, and bromophos-methyl were tested on Lumbriculus variegatus (California blackworm), Hyalella azteca (scud), and Poecilia reticulata (guppy), which yielded a high-quality database of 348 individual CBR values. Medians of CBR values ranged from 2.1 to 16.1 mmol/kg wet weight (ww) within all combinations of chemicals and species, except for the insecticide bromophos-methyl, for which the median was 1.3 mmol/kg ww. The new database thus covers about one log unit, which is considerably less than in existing databases. Medians differed maximally by a factor of 8.4 between the 7 chemicals but within one species, and by a factor of 2.6 between the three species but for individual chemicals. Accounting for the chemicals' internal distribution to different partitioning domains and

  8. Defining and analyzing retention-in-care among pregnant and breastfeeding HIV-infected women: unpacking the data to interpret and improve PMTCT outcomes. (United States)

    Rollins, Nigel C; Becquet, Renaud; Orne-Gliemann, Joanna; Phiri, Sam; Hayashi, Chika; Baller, April; Shaffer, Nathan


    The prevent mother-to-child transmission (PMTCT) "cascade" describes the programmatic steps for pregnant and breastfeeding women that influence HIV transmission rates. To this end, HIV-infected pregnant women and mothers need access to health services and adhere to antiretroviral (ARV) prophylaxis or lifetime treatment. Within the cascade, the concept of "retention-in-care" is commonly used as a proxy for adherence to ARV interventions and, even, viral suppression. Yet surprisingly, there is no standard definition of retention-in-care either for the purposes of HIV surveillance or implementation research. Implicit to the concept of retention-in-care is the sense of continuity and receipt of care at relevant time points. In the context of PMTCT, the main challenge for surveillance and implementation research is to estimate effective coverage of ARV interventions over a prolonged period of time. These data are used to inform program management and also to estimate postnatal MTCT rates. Attendance of HIV-infected mothers at clinic at 12-month postpartum is often equated with full retention in PMTCT programs over this period. Yet, measurement approaches that fail to register missed visits, or inconsistent attendance or other missing data in the interval period, fail to capture patterns of attendance and care received by mothers and children and risk introducing systematic errors and bias. More importantly, providing only an aggregated rate of attendance as a proxy for retention-in-care fails to identify specific gaps in health services where interventions to improve retention along the PMTCT cascade are most needed. In this article, we discuss how data on retention-in-care can be understood and analyzed, and what are the implications and opportunities for programs and implementation research.

  10. Working with interpreters: practical advice for use of an interpreter in healthcare. (United States)

    Hadziabdic, Emina; Hjelm, Katarina


    The aim of this descriptive commentary is to improve communication in healthcare when an interpreter is used by providing practical advice to healthcare staff when they consider using interpreters. This descriptive commentary considered the issues of preparation and implementation of interpretation sessions to reveal the complexities and dilemmas of an effective healthcare encounter with interpreters. Using the design of a discursive paper, this article seeks to explore and position of what is published in the literature on the topic studied and on the basis of previous studies to provide practical advice on the use of interpreters. The descriptive commentary showed that the interpreter should be used not only as a communication aid but also as a practical and informative guide in the healthcare system. In preparing the interpretation session, it is important to consider the type (trained professional interpreter, family member or bilingual healthcare staff as interpreters) and mode (face to face and telephone) of interpreting. Furthermore, it is important to consider the interpreter's ethnic origin, religious background, gender, language or dialect, social group, clothes, appearance and attitude. During the healthcare encounter, the interpreter should follow the recommendations given in guidelines for interpreters. Healthcare staff should choose an appropriate room and be aware of their own behaviour, appearance and attitude during the healthcare encounter. Good planning is needed, with carefully considered choices concerning the right kind of interpreter, mode of interpretation and individual preferences for the interpretation in order to deliver high-quality and cost-effective healthcare. Depending on the nature of the healthcare encounter, healthcare staff need to plan interpreting carefully and in accordance with the individuals' desires and choose the type of interpreter and mode of interpreting that best suits the need in the actual healthcare situation in

  14. Hirsch on interpretation.

    Directory of Open Access Journals (Sweden)

    Andrzej Szahaj


    Full Text Available The main aim of the article is to reconstruct and critique E.D. Hirsch’s position in the debate about the necessary conditions and results of any interpretation. The author of this article seeks to demonstrate the difficulties connected with the intentionalist approach to the theory of interpretation which is typical of E.D. Hirsch and which unjustifiably privileges authorial intention. He also attempts to uncover the hidden assumptions of this approach by showing that, generally speaking, the dualist tendencies that are present in Hirsch’s theory cannot be justified. One of the objectives of this article is to propose an alternative approach to interpretation, which has been inspired by Stanley Fish and which emphasizes the integrity and monistic nature of interpretation as well as its constructivist and inevitably evaluative character. The author points to the fact that the arbitrarily established evaluation limits are unjustified as there is an element of evaluation on every level of interpretation and that the difference between understanding and interpretation cannot be validated. Also, one cannot interpret a text without each time referring to the social and cultural context.

  20. Interpreter-mediated dentistry. (United States)

    Bridges, Susan; Drew, Paul; Zayts, Olga; McGrath, Colman; Yiu, Cynthia K Y; Wong, H M; Au, T K F


    The global movements of healthcare professionals and patient populations have increased the complexities of medical interactions at the point of service. This study examines interpreter mediated talk in cross-cultural general dentistry in Hong Kong where assisting para-professionals, in this case bilingual or multilingual Dental Surgery Assistants (DSAs), perform the dual capabilities of clinical assistant and interpreter. An initial language use survey was conducted with Polyclinic DSAs (n = 41) using a logbook approach to provide self-report data on language use in clinics. Frequencies of mean scores using a 10-point visual analogue scale (VAS) indicated that the majority of DSAs spoke mainly Cantonese in clinics and interpreted for postgraduates and professors. Conversation Analysis (CA) examined recipient design across a corpus (n = 23) of video-recorded review consultations between non-Cantonese speaking expatriate dentists and their Cantonese L1 patients. Three patterns of mediated interpreting indicated were: dentist designated expansions; dentist initiated interpretations; and assistant initiated interpretations to both the dentist and patient. The third, rather than being perceived as negative, was found to be framed either in response to patient difficulties or within the specific task routines of general dentistry. The findings illustrate trends in dentistry towards personalized care and patient empowerment as a reaction to product delivery approaches to patient management. Implications are indicated for both treatment adherence and the education of dental professionals. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Full Text Available Accurate diagnostic techniques for schistosomiasis are essential for prevalence determination and identification of positive patients. A point-of-care test for detecting schistosome circulating cathodic antigen (POC-CCA has been evaluated for its accuracy in different endemic regions. This reagent strip/dipstick based assay has showed high sensitivity for individuals with high or moderate worm burden, but the interpretation of light infections is less clear, especially for trace readings.We introduced a urine lyophilization step to the POC-CCA assay to improve its sensitivity and clarify the interpretation of traces. We evaluated POC-CCA sensitivity and specificity within individuals with low parasite burdens in a Brazilian endemic area where a high number of traces were detected. Patients that were positive for other helminths were also evaluated for cross reactions. In all cases, a combined parasitological diagnosis using Kato-Katz (24 slides and Saline Gradient (1 g of feces were used as reference. At baseline, diagnosis by POC-CCA (1-2 cassettes showed 6% sensitivity, inaccurately predicting a low prevalence of Schistosoma mansoni infections (2 POC-CCA positives/32 egg positives. After urine lyophilization, the sensitivity was increased significantly (p < 0.05. Prevalence rates changed from 2% to 32% (27 POC-CCA positives/32 egg positives, equivalent to parasitological techniques. Most of the trace readings changed to positive after lyophilization while some negatives turned into traces. Cross reaction analysis confirmed the specificity of POC-CCA.Trace readings cannot be primarily defined as positive or negative cases. It is critical to verify case-by-case by concentrating urine 10 fold by lyophilization for the diagnosis. Following lyophilization, persistent trace readings should be read as negatives. No trained technician is needed and cost is restricted to the cost of a lyophilizer and the electricity to run it.

  3. Design of interpretable fuzzy systems

    CERN Document Server

    Cpałka, Krzysztof


    This book shows that the term “interpretability” goes far beyond the concept of readability of a fuzzy set and fuzzy rules. It focuses on novel and precise operators of aggregation, inference, and defuzzification leading to flexible Mamdani-type and logical-type systems that can achieve the required accuracy using a less complex rule base. The individual chapters describe various aspects of interpretability, including appropriate selection of the structure of a fuzzy system, focusing on improving the interpretability of fuzzy systems designed using both gradient-learning and evolutionary algorithms. It also demonstrates how to eliminate various system components, such as inputs, rules and fuzzy sets, whose reduction does not adversely affect system accuracy. It illustrates the performance of the developed algorithms and methods with commonly used benchmarks. The book provides valuable tools for possible applications in many fields including expert systems, automatic control and robotics.

  4. Computer enhancement through interpretive techniques (United States)

    Foster, G.; Spaanenburg, H. A. E.; Stumpf, W. E.


    The improvement in the usage of the digital computer through the use of the technique of interpretation rather than the compilation of higher ordered languages was investigated by studying the efficiency of coding and execution of programs written in FORTRAN, ALGOL, PL/I and COBOL. FORTRAN was selected as the high level language for examining programs which were compiled, and A Programming Language (APL) was chosen for the interpretive language. It is concluded that APL is competitive, not because it and the algorithms being executed are well written, but rather because the batch processing is less efficient than has been admitted. There is not a broad base of experience founded on trying different implementation strategies which have been targeted at open competition with traditional processing methods.

  6. Interpreter perspectives of in-person, telephonic, and videoconferencing medical interpretation in clinical encounters (United States)

    Price, Erika Leemann; Pérez-Stable, Eliseo J.; Nickleach, Dana; López, Monica; Karliner, Leah S.


    Objective To examine professional medical interpreters’ perspectives of in-person and remote interpreting modalities. Methods Survey of interpreters at three medical centers assessing satisfaction with aspects of communication using each modality, and adequacy of videoconferencing medical interpretation (VMI) and telephonic interpretation for 21 common clinical scenarios in the hospital and ambulatory care settings. Results 52 interpreters completed the survey (73% response). All modalities were equally satisfactory for conveying information. Respondents favored in-person to telephonic interpretation for establishing rapport (95% versus 71%, p = .002) and for facilitating clinician understanding of patients’ social and cultural backgrounds (92% versus 69%, p = .002). Scenarios with substantial educational or psychosocial dimensions had no more than 70% of respondents rating telephonic interpretation as adequate (25–70%); for all of these scenarios, VMI represented an improvement (52–87%). Conclusion From the interpreter perspective, telephonic interpretation is satisfactory for information exchange, but less so for interpersonal aspects of communication. In scenarios where telephonic interpretation does not suffice, particularly those with substantial educational or psychosocial components, VMI offers improved communication. Practice implications Differences in interpreters’ perspectives of modalities based on communication needs and clinical scenario suggest mixed use of multiple modalities may be the best language access strategy.

    Dean, R K; Pollard, R Q


    The translation work of sign language interpreters involves much more than language. The characteristics and goings-on in the physical environment, the dynamics and interactions between the people who are present, and even the "inner noise" of the interpreter contribute to the accuracy, or lack thereof, of the resulting translation. The competent interpreter must understand and respond appropriately to the language and nonlanguage aspects of each interpreting assignment. We use the framework of demand-control theory (Karasek, 1979) to examine the complex occupation of sign language interpreting. Demand-control theory is a job analysis method useful in studies of occupational stress and reduction of stress-related illness, injury, and burnout. We describe sources of demand in the interpreting profession, including demands that arise from factors other than those associated with languages (linguistic demands). These include environmental, interpersonal, and intrapersonal demands. Karasek's concept of control, or decision latitude, is also explored in relation to the interpreting profession. We discuss the prevalence of cumulative trauma disorders (CTD), turnover, and burnout in the interpreting profession in light of demand-control theory and data from interpreter surveys, including a new survey study described herein. We conclude that nonlinguistic demand factors in particular and perceived restrictions in decision latitude likely contribute to stress, CTD, burnout, and the resulting shortage of sign language interpreters. We make suggestions for improvements in interpreter education and professional development, including the institution of an advanced, supervised professional training period, modeled after internships common in other high demand professional occupations.

Following Franke (2010, 2009, I suggest that earlier proposals failed, because they did not take into account the interactive reasoning of what else the speaker could have said, and how else the hearer could have interpreted the (alternative sentence(s.

He postulates that the marketing practices of publishers should be called a “manipulative interpretation”, insofar as the information about books and book covers fulfills a double function: that of advertising and affecting the reception of the text. Referring to the two types of interpretation, “exegesis” and “usage”, he believes that the discussed phenomena fall between these two extremes. Both the release notes and book covers are the domain of a limited “usage”, the accuracy of which verifies the market.

  5. Measurement, Interpretation and Information

    Directory of Open Access Journals (Sweden)

    Olimpia Lombardi


    Full Text Available During many years since the birth of quantum mechanics, instrumentalistinterpretations prevailed: the meaning of the theory was expressed in terms of measurementsresults. However, in the last decades, several attempts to interpret it from a realist viewpointhave been proposed. Among them, modal interpretations supply a realist non-collapseaccount, according to which the system always has definite properties and the quantum staterepresents possibilities, not actualities. But the traditional modal interpretations faced someconceptual problems when addressing imperfect measurements. The modal-Hamiltonianinterpretation, on the contrary, proved to be able to supply an adequate account of themeasurement problem, both in its ideal and its non-ideal versions. Moreover, in the non-idealcase, it gives a precise criterion to distinguish between reliable and non-reliable measurements.Nevertheless, that criterion depends on the particular state of the measured system, and thismight be considered as a shortcoming of the proposal. In fact, one could ask for a criterionof reliability that does not depend on the features of what is measured but only on theproperties of the measurement device. The aim of this article is precisely to supply such acriterion: we will adopt an informational perspective for this purpose.

  6. Interpretation and creationism. (United States)

    Ahumada, J L


    This paper is an attempt to raise questions about certain underlying and implicit assumptions in some hermeneutic and narrative approaches to psychoanalysis. Starting from the view that Freud saw interpretation in the clinical setting as an attempt to unveil the analysand's psychic reality, it is argued that he envisaged that psychoanalysis aims to interpret what is real in the analysand's inner world--an empirical line of thought underpinned by the idea of analytic neutrality and an emphasis on the analysand's capacity to judge reality. By contrast, the tendency within the hermeneutic-narrative tradition is to demote psychic reality in favour of an emphasis on the analyst's capacity to interpret in order to help his analysand construct meaning. This approach may be said to put the analyst's words in the place of those of the Creator; in other words, it amounts to a 'verbal creationism', which the author argues is rooted in the idealistic philosophy of Hegel, Vico and Descartes and, further back, can be traced to the Book of Genesis--a conclusion causing the author to express some reservations.

  11. Interpreter-mediated Cognitive Assessments: Who Wins and Who Loses? (United States)

    Haralambous, Betty; Tinney, Jean; LoGiudice, Dina; Lee, Sook Meng; Lin, Xiaoping


    The number of people with dementia from culturally and linguistically diverse (CALD) backgrounds is increasing dramatically in Australia. Accurate cognitive assessments of people from CALD backgrounds can be achieved with the use of skilled interpreters. This study aimed to explore the experience of interpreter-mediated assessments from the perspectives of clinicians, interpreters and carers. Consultations with interpreters, clinicians and carers were conducted through individual interviews and focus groups. The consultations explored participants' experiences of interpreter-mediated assessments, including perception of the interpreting process, roles of interpreters, and challenges associated with interpreter-mediated assessments. Four themes emerged across groups: (1) the importance of having professional interpreters, (2) different perceptions of the roles of interpreters, (3) clinicians' feelings of having less control over assessments, and (4) particular challenges associated with cognitive assessments. Finding from this study highlight the important role that interpreters play in cognitive assessments with immigrants. However, there appears to be different perceptions of the role between clinicians and interpreters. When these different understandings are not resolved, they will lead to tension between clinicians and interpreters. These findings highlight the importance of relational aspects in interpreter-mediated assessment and suggest that the negotiation of the relationships between clinicians and interpreters is an important factor that determines the effectiveness and accuracy of these assessments. This study highlights the need for clinicians and interpreters education of roles of all parties in interpreter-mediated cognitive assessment. Areas to be covered in education could include: common misunderstandings of interpreters roles, and practice tips on how to improve communications in assessments, such as briefing before and after the assessment.

  13. Interpreting social enterprises

    Directory of Open Access Journals (Sweden)

    Carlo Borzaga


    Full Text Available Institutional and organizational variety is increasingly characterizing advanced economic systems. While traditional economic theories have focused almost exclusively on profit-maximizing (i.e., for-profit enterprises and on publicly-owned organizations, the increasing relevance of non-profit organizations, and especially of social enterprises, requires scientists to reflect on a new comprehensive economic approach for explaining this organizational variety. This paper examines the main limitations of the orthodox and institutional theories and asserts the need for creating and testing a new theoretical framework, which considers the way in which diverse enterprises pursue their goals, the diverse motivations driving actors and organizations, and the different learning patterns and routines within organizations. The new analytical framework proposed in the paper draws upon recent developments in the theories of the firm, mainly of an evolutionary and behavioral kind. The firm is interpreted as a coordination mechanism of economic activity, and one whose objectives need not coincide with profit maximization. On the other hand, economic agents driven by motivational complexity and intrinsic, non-monetary motivation play a crucial role in forming firm activity over and above purely monetary and financial objectives. The new framework is thought to be particularly suitable to correctly interpret the emergence and role of nontraditional organizational and ownership forms that are not driven by the profit motive (non-profit organizations, mainly recognized in the legal forms of cooperative firms, non-profit organizations and social enterprises. A continuum of organizational forms ranging from profit making activities to public benefit activities, and encompassing mutual benefit organizations as its core constituent, is envisaged and discussed.

  1. Post-structural feminist interpretive interactionism. (United States)

    Jefford, Elaine; Sundin, Deborah


    To present an adaptation of interpretive interactionism that incorporates and honours feminist values and principles. Interpretive interactionism as described by Denzin can be useful when examining interactive processes. It is especially useful when events affect turning points in people's lives. When issues of power and power imbalances are of interest, a critical post-structural lens may be of use to the researcher. The authors planned to examine the interactions between midwives and women at the 'epiphaneal' points of decision making during second-stage labour. It became clear that it was necessary to honour and thus incorporate feminist principles and values in their methodology. This paper draws on a recently completed PhD project to demonstrate the application of post-structural feminist interpretive interactionism. Twenty six midwives representing each state and territory across Australia who were representative of every model of midwifery care offered in Australia were interviewed to gauge their experiences of what they believed represented good and poor case examples of decision making during second-stage labour. The authors critique the philosophical underpinnings of interpretive interactionism, and then modify these to acknowledge and incorporate post-structural and feminist ideologies. Interpretive interactionism is a useful methodology when the research question is best addressed by examining interactional processes and the meanings people make of them, especially if these occur at turning points in people's lives. Interpretive interactionism methodology can and should be improved by taking account of issues of power, feminism and post-structural values. Post-structural feminist interpretative interactionism has much to offer healthcare researchers who want to develop methodologically robust findings. Post-structural feminist interpretive interactionism enables the researcher to be more cognisant of the complex social political and historical context

  2. Interpretation for Discussions about End-of-Life Issues: Results from a National Survey of Health Care Interpreters (United States)

    Fernandez, Alicia; Kerr, Kathleen; O'Riordan, David; Pantilat, Steven Z.


    Abstract Background Communication about end-of-life issues is difficult across language barriers. Little is known about the experience of health care interpreters in these discussions. Objectives Objectives of this study were to: 1) assess the experiences of healthcare interpreters when interpreting discussions about end-of-life issues; 2) identify interpreter characteristics and experiences that may be associated with improved satisfaction and comfort with interpreting these discussions; and 3) describe interpreter training needs. Methods The study utilized an electronically administered survey distributed nationally to health care interpreters in the United States. One hundred and forty-two health care interpreters participated. Measurements included general experiences, attitudes, and perceived training needs when interpreting discussions about end-of-life issues. Results Most respondents had received a certificate in interpretation (71%, 101/142), completed more than 40 hours of training (89%, 127/142), and had more than 5 years of interpreting experience (65%, 93/142). Overall, 85% (121/142) of respondents had interpreted discussions about end-of-life issues and most interpreted multiple discussions per week. Of those interpreters who had experience with these discussions, the majority (85%, 103/121) reported feeling comfortable, but only half (48%, 58/121) reported that these discussions usually went well. Interpreters who felt clear about their role were more likely than interpreters who did not feel clear about their role to think that discussions went well (51% [57/112] versus 11% [1/9], p=0.02) and to feel comfortable interpreting (88% [98/112] versus 56% [5/9], p=0.01). Eighty percent (97/121) of respondents with experience in end-of-life discussions were personally interested in more specific training for these discussions. Attitudes and perceived training needs did not differ by interpreter demographics or qualifications. Conclusions The majority of

  3. Audiometry screening and interpretation. (United States)

    Walker, Jennifer Junnila; Cleveland, Leanne M; Davis, Jenny L; Seales, Jennifer S


    The prevalence of hearing loss varies with age, affecting at least 25 percent of patients older than 50 years and more than 50 percent of those older than 80 years. Adolescents and young adults represent groups in which the prevalence of hearing loss is increasing and may therefore benefit from screening. If offered, screening can be performed periodically by asking the patient or family if there are perceived hearing problems, or by using clinical office tests such as whispered voice, finger rub, or audiometry. Audiometry in the family medicine clinic setting is a relatively simple procedure that can be interpreted by a trained health care professional. Pure-tone testing presents tones across the speech spectrum (500 to 4,000 Hz) to determine if the patient's hearing levels fall within normal limits. A quiet testing environment, calibrated audiometric equipment, and appropriately trained personnel are required for in-office testing. Pure-tone audiometry may help physicians appropriately refer patients to an audiologist or otolaryngologist. Unilateral or asymmetrical hearing loss can be symptomatic of a central nervous system lesion and requires additional evaluation.

  4. Orientalismi: nuove prospettive interpretative

    Directory of Open Access Journals (Sweden)

    Gabriele Proglio


    Full Text Available This paper is aimed at reconsidering the concept of Orientalism in a new and multiple perspective, and at proposing a different interpretation of the relationship between culture and power, starting from Edward Said’s theoretical frame of reference. If Said’s representational model is repositioned out of structuralist and foucaultian frameworks and separated from the gramscian idea of hegemony-subordination, indeed, it may be possible to re-discuss the traditional profile identifying the Other in the European cultures. My basic assumption here is that Orientalism should not be understood as a consensus mechanism, which is able to produce diversified images of the Orient and the Oriental on demand. Although, of course, in most cases Orientalism is connected to the issue of power, its meanings could also be explained —as it will be soon shown— otherwise. Let’s take The Invisible Cities by Italo Calvino as an example. Here the narratives are not just multiple repetitions of Venice —in Said’s case, the same would hold for Europeanism—, but they could be strategically re-appropriated by those “others” and “alterities” whose bodies and identities are imposed by the Eurocentric discourse. In this sense, a double link may be identified with queer theories and postcolonial studies, and the notion of subordination will be rethought. Finally, from the above mentioned borders, a new idea of image emerges, which appears as linear, uniform and flattened only to the European gaze, whereas in actual fact it is made of imaginaries and forms of knowledge, which combine representation with the conceptualization of power relationships.

  5. [Transference interpretations and how they work: a systematic review]. (United States)

    Brumberg, Joachim; Gumz, Antje


    In clinical theory transference interpretations represent a central therapeutic technique and a specific mechanism of change in psychodynamic psychotherapies. However, the empirical basis lags behind the theoretical considerations. This article reviews both the results of empirical research on transference interpretations and their definitions of the measures employed (systematic database search for the timespan 1970-2011). The empirical results are rather heterogeneous and in part contradictory. As it turns out, specific patient characteristics (e.g., the quality of object relations), the amount and quality of transference interpretations as well as the patients' immediate reaction all decisively influence the potency of the change of transference interpretations. Currently, it is not possible to develop clear therapeutic strategies based on previous findings. Careful use of transference interpretations is generally recommended. Various methods for measuring transference interpretations exist, but the definitions do not correspond completely. A standardization of definitions would increase the comparability and interpretability of findings and greatly improve concordance with theory.

  10. Medical interpretation for immigrant workers. (United States)

    Forst, Linda; Masters, Deborah; Zanoni, Joseph; Avila, Susan; Chaidez, Francisco; Miller, Arlene


    Foreign-born workers have high rates of occupational mortality and morbidity, despite downward trends for the U.S. workforce overall. They have limited access to health care services. Medical interpreters (MIs) facilitate care of acutely injured, low-English-proficiency (LEP) patients, including those sustaining occupational injuries. Our goal was to assess the potential for MIs to serve as advocates of LEP patients injured at work and to deliver preventive messages. We conducted interviews and a focus group of MIs regarding their attitudes toward foreign-born workers, knowledge of occupational health, and perceived roles. They were familiar with occupational injuries and sympathetic toward foreign-born workers, and they described their roles as conduits, cultural brokers, and advocates for hospitals, providers, and patients. More detailed and representative data would require a larger investigation. However, the time-sensitive nature of policy-making at this point mandates that occupational health stakeholders participate in the national dialogue on standards, training, and licensure for MIs to promote improved access and quality of health care for LEP patients who have been injured at work.

  11. Equivalent statistics and data interpretation. (United States)

    Francis, Gregory


    Recent reform efforts in psychological science have led to a plethora of choices for scientists to analyze their data. A scientist making an inference about their data must now decide whether to report a p value, summarize the data with a standardized effect size and its confidence interval, report a Bayes Factor, or use other model comparison methods. To make good choices among these options, it is necessary for researchers to understand the characteristics of the various statistics used by the different analysis frameworks. Toward that end, this paper makes two contributions. First, it shows that for the case of a two-sample t test with known sample sizes, many different summary statistics are mathematically equivalent in the sense that they are based on the very same information in the data set. When the sample sizes are known, the p value provides as much information about a data set as the confidence interval of Cohen's d or a JZS Bayes factor. Second, this equivalence means that different analysis methods differ only in their interpretation of the empirical data. At first glance, it might seem that mathematical equivalence of the statistics suggests that it does not matter much which statistic is reported, but the opposite is true because the appropriateness of a reported statistic is relative to the inference it promotes. Accordingly, scientists should choose an analysis method appropriate for their scientific investigation. A direct comparison of the different inferential frameworks provides some guidance for scientists to make good choices and improve scientific practice.

      This paper reports on an on-going investigation of conversational implicature in triadic speech events: Interpreter-mediated questionings in criminal proceedings in Danish district courts. The languages involved are Danish and English, and the mode of interpreting is the consecutive mode....... The court interpreters are all state-authorized court interpreters and thus fully competent professionals.   The centrality of pragmatics in triadic speech events has been demonstrated by a number of studies (e.g. Berk-Seligson 2002, Hale 2004, Jacobsen 2002). Thus, conversational implicatures, which...... are a normal part of any interaction, occur also in courtroom interaction where questions and answers are not always entirely explicit and straightforward. However, preserving degrees of ambiguity and non-explicitness is very difficult for interpreters who may have to resort to certain strategies to translate...

  16. Migrants' perceptions of using interpreters in health care. (United States)

    Hadziabdic, E; Heikkilä, K; Albin, B; Hjelm, K


    The number of foreign-born people who do not share a common language has increased due to extensive international migration, which will increase in the future. There is limited knowledge about the users' perceptions of interpreters in health care. To describe how individuals from former Yugoslavia, living in Sweden, perceived the use of interpreters in Swedish healthcare services. A phenomenographic approach was employed. Data were collected by semi-structured interviews during 2006-2007 with 17 people, aged 29-75 years, from former Yugoslavia, living in Sweden. Three descriptive categories were identified: (1) prerequisites for good interpretation situations; (2) the interpretation situation - aspects of satisfaction or dissatisfaction; and (3) measures to facilitate and improve the interpreter situation. The interpreter's competence, attitude, appearance and an appropriate environment are important prerequisites for interpretation. The interpreter was perceived as being a communication aid and a guide in the healthcare system in terms of information and practical issues, but also as a hindrance. A desirable professional interpreter was perceived as highly skilled in medical terminology and language, working in face-to-face interaction. Using an interpreter was perceived as a hindrance, though also needed in communication with healthcare staff and as a guide in the healthcare system. Face-to-face interaction was preferred, with the interpreter as an aid to communication. As part of individual care planning it is important to use interpreters according to the patients' desires. Healthcare organizations and guidelines for interpreters need to be developed in order for patients to have easy access to highly skilled professional interpreters.

  17. Exploring the Relationship Between Eye Movements and Electrocardiogram Interpretation Accuracy (United States)

    Davies, Alan; Brown, Gavin; Vigo, Markel; Harper, Simon; Horseman, Laura; Splendiani, Bruno; Hill, Elspeth; Jay, Caroline


    Interpretation of electrocardiograms (ECGs) is a complex task involving visual inspection. This paper aims to improve understanding of how practitioners perceive ECGs, and determine whether visual behaviour can indicate differences in interpretation accuracy. A group of healthcare practitioners (n = 31) who interpret ECGs as part of their clinical role were shown 11 commonly encountered ECGs on a computer screen. The participants’ eye movement data were recorded as they viewed the ECGs and attempted interpretation. The Jensen-Shannon distance was computed for the distance between two Markov chains, constructed from the transition matrices (visual shifts from and to ECG leads) of the correct and incorrect interpretation groups for each ECG. A permutation test was then used to compare this distance against 10,000 randomly shuffled groups made up of the same participants. The results demonstrated a statistically significant (α  0.05) result in 5 of the 11 stimuli demonstrating that the gaze shift between the ECG leads is different between the groups making correct and incorrect interpretations and therefore a factor in interpretation accuracy. The results shed further light on the relationship between visual behaviour and ECG interpretation accuracy, providing information that can be used to improve both human and automated interpretation approaches.

  18. Longitudinal development of medical students' communication skills in interpreted encounters. (United States)

    Lie, D A; Bereknyei, S; Vega, C P


    Describe longitudinal skill development of medical students for the interpreted encounter. Two successive classes of students (n=92 and 100) participated in standardized clinical stations testing general communication skills and skills for working with interpreters at the end of their second year and after completing clinical clerkships during their third year. Performance was rated by standardized patients, interpreters and students using validated scales. Analysis of individual matched paired data was performed for each scale item using the Wilcoxon signed-rank test. Pairwise correlation was used to compare global scores of the standardized patient and standardized interpreter with student self-ratings. Over one year students' (n=124-168) performance worsened in behaviors for 'managing the encounter' (per interpreters' ratings) or remained unchanged (per patients' ratings). By patients' ratings, performance scores in general communication remained high. Students rated themselves as significantly improved in five of eight skills for working with interpreters despite a lack of external evidence of improvement from patient or interpreter. Students showed a trend toward underestimating their own global skills at baseline and overestimating them in comparison with the interpreters' global ratings. Students' general communication skills remained excellent over one year of training but some skills for working with interpreters worsened. Over time students showed a pattern of overrating their own skills compared with trained observers. Faculty who teach students should focus on specific behaviors that are most likely to decay without reinforcement and practice.

    Language barriers affect health care interactions. Large, randomized studies of the relative efficacy of interpreter modalities have not been conducted. To compare the efficacy of telephonic and in-person medical interpretation to visits with verified bilingual physicians. This was a prospective, randomized trial. The setting was an urban pediatric emergency department at which approximately 20% of visits are by families with limited English proficiency. The participants were families who responded affirmatively when asked at triage if they would prefer to communicate in Spanish. Randomization of each visit was to (1) remote telephonic interpretation via a double handset in the examination room, (2) an in-person emergency department-dedicated medical interpreter, or (3) a verified bilingual physician. Interviews were conducted after each visit. The primary outcome was a blinded determination of concordance between the caregivers' description of their child's diagnosis with the physician's stated discharge diagnosis. Secondary outcomes were qualitative measures of effectiveness of communication and satisfaction. Verified bilingual providers were the gold standard for noninferiority comparisons. A total of 1201 families were enrolled: 407 were randomly assigned to telephonic interpretation and 377 to in-person interpretation, and 417 were interviewed by a bilingual physician. Concordance between the diagnosis in the medical record and diagnosis reported by the family was not different between the 3 groups (telephonic: 95.1%; in-person: 95.5%; bilingual: 95.4%). The in-person-interpreter cohort scored the quality and satisfaction with their visit worse than both the bilingual and telephonic cohorts (P bilingual-provider cohort were less satisfied with their language service than those in the in-person and telephonic cohorts (P bilingual provider as a gold standard, noninferiority was demonstrated for both interpreter modalities (telephonic and in-person) for quality

  1. Interpreting Sustainability for Urban Forests

    Directory of Open Access Journals (Sweden)

    Camilo Ordóñez


    Full Text Available Incisive interpretations of urban-forest sustainability are important in furthering our understanding of how to sustain the myriad values associated with urban forests. Our analysis of earlier interpretations reveals conceptual gaps. These interpretations are attached to restrictive definitions of a sustainable urban forest and limited to a rather mechanical view of maintaining the biophysical structure of trees. The probing of three conceptual domains (urban forest concepts, sustainable development, and sustainable forest management leads to a broader interpretation of urban-forest sustainability as the process of sustaining urban forest values through time and across space. We propose that values—and not services, benefits, functions or goods—is a superior concept to refer to what is to be sustained in and by an urban forest.

    Lázár, Zsolt I; Papp, István; Varga, Levente; Járai-Szabó, Ferenc; Deritei, Dávid; Ercsey-Ravasz, Mária


    Given a network, the statistical ensemble of its graph-Voronoi diagrams with randomly chosen cell centers exhibits properties convertible into information on the network's large scale structures. We define a node-pair level measure called Voronoi cohesion which describes the probability for sharing the same Voronoi cell, when randomly choosing g centers in the network. This measure provides information based on the global context (the network in its entirety), a type of information that is not carried by other similarity measures. We explore the mathematical background of this phenomenon and several of its potential applications. A special focus is laid on the possibilities and limitations pertaining to the exploitation of the phenomenon for community detection purposes.

    Ewing, Bonnie; Hayden-Miles, Marie


    Contemporary practices in nursing education call for changes that will assist students in understanding a complex, rapidly changing world. Narrative pedagogy is an approach that offers teachers a way to actively engage students in the process of teaching and learning. The narrative approach provides ways to think critically, make connections, and ask questions to gain understanding through dialogue. The hermeneutic circle of understanding offers a way to interpret stories and discover meaning. Narratives exist in art forms that can be interpreted to evoke discussions and thinking that relate to nursing practice. Art interpretation is a way to gain access to others and acquire a deeper appreciation for multiple perspectives in the teaching-learning process. Copyright 2011, SLACK Incorporated.

    Splevins, Katie A; Cohen, Keren; Joseph, Stephen; Murray, Craig; Bowley, Jake


    An emerging evidence base indicates that posttraumatic growth might be experienced vicariously by those working alongside trauma survivors. In this study we explored the vicarious experiences of eight interpreters working in a therapeutic setting with asylum seekers and refugees. We adopted a qualitative approach, using semistructured interviews and interpretative phenomenological analysis. Four interrelated themes emerged from the findings: feeling what your client feels, beyond belief, finding your own way to deal with it, and a different person. Although all participants experienced distress, they also perceived themselves to have grown in some way. The implications for a theory of vicarious posttraumatic growth are discussed, along with clinical applications.

    Basic information has been presented concerning leukocyte (neutrophil, monocyte, lymphocyte, eosinophil, and basophil) function, production, kinetics, and response to various physiological and disease states. Using this information, veterinary practitioners should be able to interpret leukogram data from sick and healthy dogs and cats. Specifically, characteristic leukogram patterns such as physiological leukocytosis, corticosteroid-associated changes, and the presence of infection or severe inflammation should be recognized. In addition, interpretation of individual leukocyte responses should be possible. Several tables have been provided to assist in constructing a differential diagnosis to explain increases or decreases in absolute leukocyte numbers that lie outside of expected reference intervals.

    Full Text Available A key change agent role is to help clients understand the systems to which they belong to improve performance. A major challenge is how to facilitate this understanding. Typically, the change agent collects the data and provides an interpretation about its significance for the client organization. This approach, however, often meets with resistance. What is needed is an approach that engages the author of the data in its interpretation and this article introduces just such an approach—PathMAP®. A case study is used to introduce PathMAP® and show how it can be used to engage system agents in a rigorous process of data interpretation leading to an increased understanding of the variables that influence system dynamics and of how to engage the system in change. This article will demonstrate how PathMAP® enables change agents to get an accurate picture of the current state of an organization by identifying the key issues facing the organization and their interrelationship, and using this knowledge to create meaningful action plans that make deep and intuitive sense to organization’s members.

    We have reported the results of a cluster randomized trial of rural Kenyan hospitals evaluating the effects of an intervention to introduce care based on best-practice guidelines. In parallel work we described the context of the study, explored the process and perceptions of the intervention, and undertook a discrete study on health worker motivation because this was felt likely to be an important contributor to poor performance in Kenyan public sector hospitals. Here, we use data from these multiple studies and insights gained from being participants in and observers of the intervention process to provide our explanation of how intervention effects were achieved as part of an effort to better understand implementation in low-income hospital settings. Initial hypotheses were generated to explain the variation in intervention effects across place, time, and effect measure (indicator) based on our understanding of theory and informed by our implementation experience and participant observations. All data sources available for hospitals considered as cases for study were then examined to determine if hypotheses were supported, rejected, or required modification. Data included transcriptions of interviews and group discussions, field notes and that from the detailed longitudinal quantitative investigation. Potentially useful explanatory themes were identified, discussed by the implementing and research team, revised, and merged as part of an iterative process aimed at building more generic explanatory theory. At the end of this process, findings were mapped against a recently reported comprehensive framework for implementation research. A normative re-educative intervention approach evolved that sought to reset norms and values concerning good practice and promote 'grass-roots' participation to improve delivery of correct care.

  8. Interpretation bias characterizes trait rumination. (United States)

    Mor, Nilly; Hertel, Paula; Ngo, Thuy Anh; Shachar, Tal; Redak, Shimrit


    Rumination, a maladaptive cognitive style of responding to negative mood, is thought to be maintained by a variety of cognitive biases. However, it is unknown whether rumination is characterized by interpretation biases. Two experiments examined the link between rumination and interpretation biases, revealed in lexical-decision tasks (LDT). A homograph with both benign and ruminative or otherwise negative meaning was presented on each trial and followed by a letter string, to which participants responded by judging whether it was a word or a non-word. Letter strings were non-words or words related or unrelated to one meaning of the homograph. In both experiments, faster latencies to respond to targets related to the ruminative meaning of the homographs were produced by students with higher scores on self-report measures of rumination. Moreover, these biases were associated with both brooding, the maladaptive form of rumination, and reflection, the more adaptive component. No measure of rumination was significantly correlated with general biases toward negative meaning (Experiment 1) or with threatening interpretations of homographs (Experiment 2). The paucity of available rumination-related homographs dictated the use of non-fully randomized stimuli presentation (Experiment 1) or the use of only one set of the meanings associated with the homographs (Experiment 2). Rumination is associated with a tendency to interpret ambiguous information in a rumination-consistent manner. This tendency may exacerbate ruminative thinking and can possibly be a target for future intervention. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Van Dijk, Rick; Boers, Eveline; Christoffels, Ingrid; Hermans, Daan


    The quality of interpretations produced by sign language interpreters was investigated. Twenty-five experienced interpreters were instructed to interpret narratives from (a) spoken Dutch to Sign Language of The Netherlands (SLN), (b) spoken Dutch to Sign Supported Dutch (SSD), and (c) SLN to spoken Dutch. The quality of the interpreted narratives was assessed by 5 certified sign language interpreters who did not participate in the study. Two measures were used to assess interpreting quality: the propositional accuracy of the interpreters' interpretations and a subjective quality measure. The results showed that the interpreted narratives in the SLN-to-Dutch interpreting direction were of lower quality (on both measures) than the interpreted narratives in the Dutch-to-SLN and Dutch-to-SSD directions. Furthermore, interpreters who had begun acquiring SLN when they entered the interpreter training program performed as well in all 3 interpreting directions as interpreters who had acquired SLN from birth.

  9. Phonological Interpretation into Preordered Algebras (United States)

    Kubota, Yusuke; Pollard, Carl

    We propose a novel architecture for categorial grammar that clarifies the relationship between semantically relevant combinatoric reasoning and semantically inert reasoning that only affects surface-oriented phonological form. To this end, we employ a level of structured phonology that mediates between syntax (abstract combinatorics) and phonology proper (strings). To notate structured phonologies, we employ a lambda calculus analogous to the φ-terms of [8]. However, unlike Oehrle's purely equational φ-calculus, our phonological calculus is inequational, in a way that is strongly analogous to the functional programming language LCF [10]. Like LCF, our phonological terms are interpreted into a Henkin frame of posets, with degree of definedness ('height' in the preorder that interprets the base type) corresponding to degree of pronounceability; only maximal elements are actual strings and therefore fully pronounceable. We illustrate with an analysis (also new) of some complex constituent-order phenomena in Japanese.

  10. Modelling Metamorphism by Abstract Interpretation (United States)

    Dalla Preda, Mila; Giacobazzi, Roberto; Debray, Saumya; Coogan, Kevin; Townsend, Gregg M.

    Metamorphic malware apply semantics-preserving transformations to their own code in order to foil detection systems based on signature matching. In this paper we consider the problem of automatically extract metamorphic signatures from these malware. We introduce a semantics for self-modifying code, later called phase semantics, and prove its correctness by showing that it is an abstract interpretation of the standard trace semantics. Phase semantics precisely models the metamorphic code behavior by providing a set of traces of programs which correspond to the possible evolutions of the metamorphic code during execution. We show that metamorphic signatures can be automatically extracted by abstract interpretation of the phase semantics, and that regular metamorphism can be modelled as finite state automata abstraction of the phase semantics.

  11. Using professional interpreters in undergraduate medical consultation skills teaching

    Full Text Available Aarti Bansal,1 Jennifer Swann,1 William Henry Smithson2 1Academic Unit of Primary Medical Care, University of Sheffield, UK; 2Department of General Practice, University College Cork, Cork, Ireland Abstract: The ability to work with interpreters is a core skill for UK medical graduates. At the University of Sheffield Medical School, this teaching was identified as a gap in the curriculum. Teaching was developed to use professional interpreters in role-play, based on evidence that professional interpreters improve health outcomes for patients with limited English proficiency. Other principles guiding the development of the teaching were an experiential learning format, integration to the core consultation skills curriculum, and sustainable delivery. The session was aligned with existing consultation skills teaching to retain the small-group experiential format and general practitioner (GP tutor. Core curricular time was found through conversion of an existing consultation skills session. Language pairs of professional interpreters worked with each small group, with one playing patient and the other playing interpreter. These professional interpreters attended training in the scenarios so that they could learn to act as patient and family interpreter. GP tutors attended training sessions to help them facilitate the session. This enhanced the sustainability of the session by providing a cohort of tutors able to pass on their expertise to new staff through the existing shadowing process. Tutors felt that the involvement of professional interpreters improved student engagement. Student evaluation of the teaching suggests that the learning objectives were achieved. Faculty evaluation by GP tutors suggests that they perceived the teaching to be worthwhile and that the training they received had helped improve their own clinical practice in consulting through interpreters. We offer the following recommendations to others who may be interested in

    Talya Miron-Shatz


    Full Text Available Genetic screening for BRCA1 and BRCA2 gives women the opportunity for early detection, surveillance, and intervention. One key feature of genetic testing and counseling is the provision of personal lifetime risk. However, little attention has been paid to how women interpret lifetime risk information, despite the fact that they base screening, treatment and family planning decisions on such information. To study this vital issue, we set out to test the ability of women to choose the most appropriate interpretation of National Cancer Institute's (NCI message about lifetime risk of developing cancer for a woman with altered BRCA1 and BRCA2 genes. Participants included 277 women who had not undergone genetic testing or had cancer and 207 women who had undergone genetic testing or had cancer. Over 50\\% of the women who had not undergone genetic testing or had cancer and 40\\% of those who had undergone genetic testing or had cancer misunderstood NCI's information. Furthermore, in line with a growing body of research, we found that high numeracy level (objective or subjective is positively associated with a woman's ability to correctly interpret NCI's message.

    Filman, Robert E.


    I return to the question of what distinguishes AOP languages by considering how the interpreters of AOP languages differ from conventional interpreters. Key elements for static transformation are seen to be redefinition of the set and lookup operators in the interpretation of the language. This analysis also yields a definition of crosscutting in terms of interlacing of interpreter actions.

  4. Trend figures assist with untrained emergency electroencephalogram interpretation. (United States)

    Kobayashi, Katsuhiro; Yunoki, Kosuke; Zensho, Kazumasa; Akiyama, Tomoyuki; Oka, Makio; Yoshinaga, Harumi


    Acute electroencephalogram (EEG) findings are important for diagnosing emergency patients with suspected neurological disorders, but they can be difficult for untrained medical staff to interpret. In this research, we will develop an emergency EEG trend figure that we hypothesize will be more easily understood by untrained staff compared with the raw original traces. For each of several EEG patterns (wakefulness, sleep, seizure activity, and encephalopathy), trend figures incorporating information on both amplitude and frequency were built. The accuracy of untrained reviewers' interpretation was compared with that of the raw EEG trace interpretation. The rate of correct answers was significantly higher in response to the EEG trend figures than to the raw traces showing wakefulness, sleep, and encephalopathy, but there was no difference when seizure activity patterns were viewed. The rates of misjudging normal or abnormal findings were significantly lower with the trend figures in the wakefulness pattern; in the other patterns, misjudgments were equally low for the trend figures and the raw traces. EEG trend figures improved the accuracy with which untrained medical staff interpreted emergency EEGs. Emergency EEG figures that can be understood intuitively with minimal training might improve the accuracy of emergency EEG interpretation. However, additional studies are required to confirm these results because there may be many types of clinical EEGs that are difficult to interpret.

  5. Electrocardiogram interpretation skills in pediatric residents

    Directory of Open Access Journals (Sweden)

    Crocetti Michael


    Full Text Available Objective : The primary objective of this study was to evaluate pediatric residents′ ability to correctly identify electrocardiogram (ECG findings and pair them to a corresponding cardiac diagnosis. Methods: Forty-six pediatric residents from the Johns Hopkins Children′s Center were surveyed to evaluate their ability to interpret ECGs and factors affecting that ability. Included in the survey was a packet of 10 patient vignettes each accompanied by a 12-lead ECG. The primary outcome variable was the resident′s score of correctly paired ECG findings with the appropriate cardiac diagnosis. One point was given for each pair correctly identified for a maximum of 10 points. Simple and multiple linear regression was used to estimate the magnitude and significance of any association between score of correct responses and resident year, completion of a pediatric cardiology rotation, self-rated ability to read ECGs, and training received in reading ECGs. Results : The mean number of correct ECG findings and cardiac diagnosis pairings out of 10 for the PGY 1 group was 4.1 ± 3, PGY 2 group 4.9 ± 2.9, PGY 3 group 6.6 ± 2, and the PGY 4 group 6.8 ± 1.7. In the unadjusted linear regression model, the PGY 3 group correctly identified 2.4 more pairings compared to the PGY 1 group (P =0.02. Those who completed a pediatric cardiology rotation correctly identified 2.5 more pairings compared to those who did not complete a rotation (P=0.001. Conclusions: ECG interpretation significantly improved from PGY 1 to PGY 3. Educational programs involving ECG interpretation should target those diagnoses with high clinical severity and average to poor resident knowledge.

Several well known algorithms from the static analysis literature are then explained (such as pointer analyses, memory analyses, weak relational abstract domains, function summarization, etc.). It ends with interesting problems we encountered (such as C++ analysis with exception handling, or the detection of integer overflow).

  9. Experiences of Kurdish war-wounded refugees in communication with Swedish authorities through interpreter. (United States)

    Fatahi, Nabi; Nordholm, Lena; Mattsson, Bengt; Hellström, Mikael


    To study experiences of war-wounded Kurdish refugees with respect to cross-cultural communication through interpreters. Semi-structured interviews were conducted with ten men, aged 31-42. Content analysis was used for analysis and interpretation of data. War-wounded Kurdish refugees experienced a number of difficulties regarding communication through interpreters, mainly related to the insufficient language link to the Swedish authorities, particularly health care personnel. In many instances, interpreters were selected based on the immigrant's citizenship rather than mother tongue, leading to a more complex, tri-lingual interpretation situation. Differences in cultural background, fear, suspicion and lack of confidence in interpreters were addressed as other problems by the participants. Interpreter competence and patient confidence in the interpreter are essential for an adequate cross-cultural health communication. Assignment of interpreters should be based on knowledge of the patient's/client's mother tongue, rather than citizenship, and the outcome is improved by a common ethnic and cultural background of interpreter and patient/client. Our study should be considered as a pilot study, and the results should be validated in larger cohorts as well as in other ethnic and language groups. In order to minimize communication misunderstandings, complicated tri-lingual interpretation situations should be avoided. Interpreters should ideally be assigned according to patient's/client's mother tongue rather than citizenship. Interpreters' competence and patient's/client's confidence in interpreter may have significant impact on communication outcome. Copyright 2009 Elsevier Ireland Ltd. All rights reserved.

  10. Telephone interpreter discrepancies: videotapes of Hmong medication consultations. (United States)

    Lor, Maichou; Chewning, Betty


    Over 25 million people in the USA have limited English proficiency (LEP). Interpreters are often used to facilitate communication with health care providers. Little is currently known about interpreter quality. To explore the quality of telephone interpretation during medication consultations between Hmong clients and their pharmacists. This descriptive study analyzed transcripts from videos of consultations between six triads of Hmong patients, pharmacy students and interpreters. Analysis was divided into two segments: (1) pharmacy: communication from student pharmacist the interpreter to patient and (2) patient: communication from patient to interpreter to student pharmacist. Researchers coded transcripts separately then compared codes. The six encounters yielded 496 communications with 275 discrepancies including omissions, additions, and word substitutions. Pharmacy to patient communications included, 45% (118/262) of omissions, 27.5% (72/262) of substitutions, and 15.6% (41/262) of additions. The patient to provider communications included, 8.1% (19/234) of omissions, 6.0% (14/234) of substitutions, and 4.2% (10/234) of word additions. Some omissions, additions, and substitutions in the pharmacy to patient communications were classified as potentially clinically relevant. Significantly, substantial discrepancies between the student pharmacists' comments and the interpretation to patients had potential for hindering relationship building between patients and their providers. Pharmacists may assume that the presence of an interpreter ensures accurate communication from pharmacist to patient and from patient to pharmacist. This study confirms that those assumptions may not be valid. These findings highlight the need to improve pharmacy education and interventions to improve pharmacist communication with LEP patients. © 2015 Royal Pharmaceutical Society.

    Roderick J. Lawrence


    Full Text Available Since the 1950s academics and professionals have proposed a number of disciplinary and sector based interpretations of why, when and where households move or choose to stay in the same housing unit at different periods of the life cycle and especially the family cycle. This article challenges studies that only analyse one set of factors. The article stems from a synthesis of 20 years of research by the author who  has an interdisciplinary training in the broad field of people-environment relations. First, it reviews some key concepts related to human ecology, including housing, culture, identity and cultivation. Then it will consider how these concepts can be applied to interpret residential mobility using an interdisciplinary approach. An empirical case study of residential mobility in Geneva, Switzerland is presented in order to show how this approach can help improve our understanding of the motives people have regarding the wish to stay in their residence or to move elsewhere.

  14. [Quality scale for preschool spirometry interpretation]. (United States)

    Gatto, Francisca; Bedregal, Paula; Ubilla, Carlos; Barrientos, Hortensia; Caussade, Solange


    Since 2007, there are international guidelines for implementation and interpretation of spirometry in preschool children. A percentage of these patients cannot obtain maneuvers that meet all eligibility criteria. The objective of this study was to develop a quality scale for interpreting these partially acceptable spirometry. Delphi methodology was used, which allows to reach consensus among experts analyzing a defined problem. We invited to participate pediatric pneumologists dedicated to lung function and who participated actively in scientific specialty societies in Chile. Successive rounds were conducted with questionnaires about criteria used to assess spirometry in preschool children. These criteria define the acceptability of spirometric maneuvers according to international guidelines. Proposed quality grades were “very good”, “good”, “fair” and “bad”. Thirteen of the 15 invited experts accepted our invitation. In the first round 9 disagreed with the degree of “regular” quality. In the second round this was removed and 11 experts answered, 9 of them agreed with the use of this new version. The most contentious criterion was the end of expiration. Most experts agreed with the final scale, using “very good”, “good” and “bad” judgments. This would help to improve the performance of spirometry in children between 2 and 5 years.

  15. Interpretation of ultrasonic images; Interpretation von Ultraschall-Abbildungen

    Energy Technology Data Exchange (ETDEWEB)

    Mueller, W.; Schmitz, V.; Kroening, M. [Fraunhofer-Institut fuer Zerstoerungsfreie Pruefverfahren, Saarbruecken (Germany)


    During the evaluation of ultrasonic images, e.g. SAFT-reconstructed B-scan images (SAFT=Synthetic Aperture Focusing Technique) it is often difficult to decide, what is the origin of reconstructed image points: were they caused by defects, specimens geometry or mode-conversions. To facilitate this evaluation a tool based on the comparison of data was developed. Different kinds of data comparison are possible: identification of that RF-signals, which caused the reconstructed image point. This is the comparison of a reconstructed image with the corresponding RF-data. Comparison of two reconstructed images performing a superposition using logical operators. In this case e.g. the reconstruction of an unknown reflector is compared with that of a known one. Comparison of raw-RF-data by simultaneous scanning through two data sets. Here the echoes of an unknown reflector are compared with the echoes of a known one. The necessary datasets of known reflectors may be generated experimentally on reference reflectors or modelled. The aim is the identification of the reflector type, e.g. cracklike or not, the determination of position, size and orientation as well as the identification of accompanying satellite echoes.

The quality of the interpreted narratives…

  17. Direct interpretation of dreams: typology. (United States)

    van den Daele, L


    The dream typology assorts dreams into three major categories: dreams whose origin is endogenous, exogenous, or relational. Dreams of the first type arise from somatic needs, feelings, and states that accompany organismic adjustments to system requirements. Dreams of the second type are initiated by kinetic and dispositional tendencies toward engagement and exploration of the outer world. And dreams of the third type derive from interpersonal dispositions to interaction and relationship with other people. Within each category, dreams may occur at different levels of complexity. The dream typology permits the integration of psychoanalytic observations about the dreams from a variety of perspectives within a common framework. Freud's view that a dream is a wish fulfillment finds its primary niche in endogenous need, wish fulfillment, and convenience dreams. Kohut's observations about self-state dreams and inner regulation (1971, 1977) are accommodated to the middle range of endogenous dreams, and Jung's individuation dreams (1930) occupy the advanced range. Similarly, Bonime's interpersonal approach to dream interpretation (1962) is encompassed by relational dreams of the middle level. In addition, types and modes of dreams that are only infrequently encountered in clinical psychoanalysis are accommodated. The dream typology suggests that different psychoanalytic theories are like the position papers that might have derived from the fabled committee of learned blind who were commissioned to determine the appearance of an elephant. Each individual got a hold on some part, but could not see the whole; so for each, the part became the whole. The psychoanalytic theorist is in exactly an analogous position because, in fact, he is blind to the extent of the unconscious and is constrained to what he can infer. What he can infer depends on cohort, client population, and how he calibrates his observations. The result has been procrustean interpretation, dissention, and a

  18. Interpreting neurodynamics: concepts and facts. (United States)

    Atmanspacher, Harald; Rotter, Stefan


    The dynamics of neuronal systems, briefly neurodynamics, has developed into an attractive and influential research branch within neuroscience. In this paper, we discuss a number of conceptual issues in neurodynamics that are important for an appropriate interpretation and evaluation of its results. We demonstrate their relevance for selected topics of theoretical and empirical work. In particular, we refer to the notions of determinacy and stochasticity in neurodynamics across levels of microscopic, mesoscopic and macroscopic descriptions. The issue of correlations between neural, mental and behavioral states is also addressed in some detail. We propose an informed discussion of conceptual foundations with respect to neurobiological results as a viable step to a fruitful future philosophy of neuroscience.

  19. Interpretation of neonatal chest radiography

    Energy Technology Data Exchange (ETDEWEB)

    Yoon, Hye Kyung [Dept. of Radiology, Kangwon National University Hospital, Chuncheon (Korea, Republic of)


    Plain radiographs for infants in the neonatal intensive care unit are obtained using the portable X-ray equipment in order to evaluate the neonatal lungs and also to check the position of the tubes and catheters used for monitoring critically-ill neonates. Neonatal respiratory distress is caused by a variety of medical or surgical disease conditions. Clinical information about the gestational week, respiratory symptoms, and any events during delivery is essential for interpretation of the neonatal chest radiographs. Awareness of common chest abnormality in the prematurely born or term babies is also very important for chest evaluation in the newborn. Furthermore, knowledge about complications such as air leaks and bronchopulmonary dysplasia following treatment are required to accurately inform the clinicians. The purpose of this article was to briefly review radiographic findings of chest diseases in newborns that are relatively common in daily practice.

  20. Touch design and narrative interpretation

    DEFF Research Database (Denmark)

    Zhao, Sumin; Unsworth, Len


    Interactivity is often considered as the defining feature of a book app. However, what constitutes interactivity in the context of apps is not always clear. We postulate in this chapter a multimodal social semiotic theory of interactivity, which considers interactivity as not simply a function...... of technology, but also a resource for meaning making. We distinguish two basic types of interactivity—intra-text and extra-text—incorporated in the touch design, and explore the different functions they perform in a broad range of picture book apps. In particular, we look at the app version of The Heart...... and the Bottle in depth, and illustrate how interactive design elements help to create an interpretative possibility of the story. We suggest that a better understanding of interactive touch design would promote more effective adult-child interactions around mobile applications....

  1. Interpreting physicochemical experimental data sets. (United States)

    Colclough, Nicola; Wenlock, Mark C


    With the wealth of experimental physicochemical data available to chemoinformaticians from the literature, commercial, and company databases an increasing challenge is the interpretation of such datasets. Subtle differences in experimental methodology used to generate these datasets can give rise to variations in physicochemical property values. Such methodology nuances will be apparent to an expert experimentalist but not necessarily to the data analyst and modeller. This paper describes the differences between common methodologies for measuring the four most important physicochemical properties namely aqueous solubility, octan-1-ol/water distribution coefficient, pK(a) and plasma protein binding highlighting key factors that can lead to systematic differences. Insight is given into how to identify datasets suitable for combining.

    We describe a simple step-by-step guide to qualitative interpretation of galaxy spectra. Rather than an alternative to existing automated tools, it is put forward as an instrument for quick-look analysis and for gaining physical insight when interpreting the outputs provided by automated tools. Though the recipe is for general application, it was developed for understanding the nature of the Automatic Spectroscopic K-means-based (ASK) template spectra. They resulted from the classification of all the galaxy spectra in the Sloan Digital Sky Survey data release 7, thus being a comprehensive representation of the galaxy spectra in the local universe. Using the recipe, we give a description of the properties of the gas and the stars that characterize the ASK classes, from those corresponding to passively evolving galaxies, to H II galaxies undergoing a galaxy-wide starburst. The qualitative analysis is found to be in excellent agreement with quantitative analyses of the same spectra. We compare the mean ages of the stellar populations with those inferred using the code STARLIGHT. We also examine the estimated gas-phase metallicity with the metallicities obtained using electron-temperature-based methods. A number of byproducts follow from the analysis. There is a tight correlation between the age of the stellar population and the metallicity of the gas, which is stronger than the correlations between galaxy mass and stellar age, and galaxy mass and gas metallicity. The galaxy spectra are known to follow a one-dimensional sequence, and we identify the luminosity-weighted mean stellar age as the affine parameter that describes the sequence. All ASK classes happen to have a significant fraction of old stars, although spectrum-wise they are outshined by the youngest populations. Old stars are metal-rich or metal-poor depending on whether they reside in passive galaxies or in star-forming galaxies.

    Brownell, Hiram; Lundgren, Kristine; Cayer-Meade, Carol; Milione, Janet; Katz, Douglas I; Kearns, Kevin


    To improve oral interpretation of metaphors by patients with traumatic brain injury (TBI). Both single subject experimental design and group analysis. Patients' homes. Eight adult patients with moderate to severe traumatic brain injury sustained 3 to 20 years before testing. The Metaphor Training Program consisted typically of 10 baseline sessions, 3 to 9 1-hour sessions of structured intervention, and 10 posttraining baseline sessions. Training used extensive practice with simple graphic displays to illustrate semantic associations. Quality of orally produced metaphor interpretation and accuracy of line orientation judgments served as dependent measures obtained during baseline, training, posttraining, and at a 3- to 4-month follow-up. Untrained line orientation judgments provided a control measure. Group data showed significant improvement in metaphor interpretation but not in line orientation. Six of 8 patients individually demonstrated significant improvement in metaphor interpretation. Gains persisted for 3 of the 6 patients at the 3- to 4-month follow-up. The Metaphor Training Program can improve cognitive-communication performance for individuals with moderate to severe traumatic brain injury. Results support the potential for treating patients' residual cognitive-linguistic deficits.

  9. Decoherence and the many worlds interpretation

    Energy Technology Data Exchange (ETDEWEB)

    Weigelt, Carsten Thomas [University Bonn (Germany)


    The theory of decoherence gives us a good account (at least for open systems) of how classical properties emerge from the quantum world. Recent experiments based on decoherence offers strong arguments against the quantum-classical division proposed by the early Copenhagen Interpretation. But even if decoherence may support the view that quantum mechanics can be considered as fundamental theory the question remains if this sheds new light to the question of how a realistic interpretation of quantum theory can be achieved? In the last years proponents of decoherence pointed out that the theory fits perfectly into the framework of many worlds interpretations. The question that I address is, in what sense these interpretations can be considered as realistic interpretations? To answer this question I argue that in the context of decoherence we have strong reasons to interpret quantum states in a realistic sense. A problem for many worlds interpretations arises when the meaning of Everett's relative states is considered since these interpretations strongly dependent on the interpretation of relative states. I show that einselection proposed by the decoherence theory will determine Everett's relative states in an objective sense but these states must be interpreted as epistemic states. I conclude that this ambiguity between realistic interpreted quantum states and epistemic relative states limits the strict realistic character of many worlds interpretation.

  13. Assuring the quality of interpretative comments in clinical chemistry. (United States)

    Vasikaran, Samuel; Sikaris, Kenneth; Kilpatrick, Eric; French, Jane; Badrick, Tony; Osypiw, Jacqui; Plebani, Mario


    The provision of interpretative advice on laboratory results is a post-analytic activity and an integral part of clinical laboratory services. It is valued by healthcare workers and has the potential to prevent or reduce errors and improve patient outcomes. It is important to ensure that interpretative comments provided by laboratory personnel are of high quality: comments should be patient-focused and answer the implicit or explicit question raised by the requesting clinician. Comment providers need to be adequately trained and qualified and be able to demonstrate their proficiency to provide advice on laboratory reports. External quality assessment (EQA) schemes can play a part in assessing and demonstrating the competence of such laboratory staff and have an important role in their education and continuing professional development. A standard structure is proposed for EQA schemes for interpretative comments in clinical chemistry, which addresses the scope and method of assessment including nomenclature and marking scales. There is a need for evidence that participation in an EQA program for interpretative commenting facilitates improved quality of comments. It is proposed that standardizing goals and methods of assessment as well as nomenclature and marking scales may help accumulate evidence to demonstrate the impact of participation in EQA for interpretative commenting on patient outcome.

    Full Text Available Coasts were formed with the overall shape of earth's surface. Τhey represent a landform, as determined by the science of geomorphology. Being the boundary between land and sea, they present important features – particularities such as water currents, waves, winds, estuaries, drainage network, pollution etc. Coasts are examined at various levels: continents – oceans, states – large seas, as for example Mediterranean Sea. Greece, because of its horizontal and vertical partitioning, presents great extent and variety of coasts as mainland, peninsulas and islands. Depending on geomorphology, geology, soils, hydrology, land use of the inland and the coasts themselves, these are very diverse. Photogrammetry and Remote Sensing (defined by Statute II of ISPRS is the art, science, and technology of obtaining reliable information from non-contact imaging and other sensor systems about the Earth and its environment, and other physical objects and of processes through recording, measuring, analyzing and representation. This paper concerns critical considerations on the above. It also includes the case of Thessaloniki coasts in Greece, particularly river estuaries areas (river delta. The study of coastal areas of the wide surroundings of Thessaloniki city includes visual image interpretation – digital image processing techniques on satellite data of high spatial resolution.

  15. Fitting and interpreting occupancy models.

    Directory of Open Access Journals (Sweden)

    Alan H Welsh

    Full Text Available We show that occupancy models are more difficult to fit than is generally appreciated because the estimating equations often have multiple solutions, including boundary estimates which produce fitted probabilities of zero or one. The estimates are unstable when the data are sparse, making them difficult to interpret, and, even in ideal situations, highly variable. As a consequence, making accurate inference is difficult. When abundance varies over sites (which is the general rule in ecology because we expect spatial variance in abundance and detection depends on abundance, the standard analysis suffers bias (attenuation in detection, biased estimates of occupancy and potentially finding misleading relationships between occupancy and other covariates, asymmetric sampling distributions, and slow convergence of the sampling distributions to normality. The key result of this paper is that the biases are of similar magnitude to those obtained when we ignore non-detection entirely. The fact that abundance is subject to detection error and hence is not directly observable, means that we cannot tell when bias is present (or, equivalently, how large it is and we cannot adjust for it. This implies that we cannot tell which fit is better: the fit from the occupancy model or the fit ignoring the possibility of detection error. Therefore trying to adjust occupancy models for non-detection can be as misleading as ignoring non-detection completely. Ignoring non-detection can actually be better than trying to adjust for it.

  16. Psychoanalytic interpretation and cognitive transformation. (United States)

    Basch, M F


    Psychoanalytic metapsychology should be recognized for what it is, namely a theory of cognition and affect that is not derived directly from clinical data but is advanced in order to provide the development background that will let us deal with the clinical findings of psychoanalysis as aberrations of and deviations from the normal and expected evolution of the thinking process. Its cornerstone is Freud's belief that thought depends on the forging of links between the sensory perception of objects and their appropriate verbal descriptions. He made no secret of his dissatisfaction with his metapsychology and repeatedly revised it in an attempt to encompass those clinical discoveries of psychoanalysis that outstripped the explanatory power of that metapsychology and demonstrated its shortcomings. Using what we now know about normal development in infancy and childhood through the work of Piaget, Vygotsky and other investigators, it is possible to formulate an explanatory theory that does justice to the varied and complex findings uncovered by the application of the psychoanalytic method. For example, the significance of Freud's postulated second censorship between the preconscious and consciousness, as well as the importance of the defence of disavowal that Freud emphasized in his writings after 1927, can now be accounted for with a theory of thought formation that was not available to the founder of psychoanalysis. The implications of this proposed reformulation for psychoanalytic interpretation and for the application of psychoanalysis to an increasingly wide range of psychopathology is discussed in some detail.

  17. Machine Learning in Radiology: Applications Beyond Image Interpretation. (United States)

    Much attention has been given to machine learning and its perceived impact in radiology, particularly in light of recent success with image classification in international competitions. However, machine learning is likely to impact radiology outside of image interpretation long before a fully functional "machine radiologist" is implemented in practice. Here, we describe an overview of machine learning, its application to radiology and other domains, and many cases of use that do not involve image interpretation. We hope that better understanding of these potential applications will help radiology practices prepare for the future and realize performance improvement and efficiency gains.

    Schenker, Yael; Pérez-Stable, Eliseo J; Nickleach, Dana; Karliner, Leah S


    Professional interpreter use improves the quality of care for patients with limited English proficiency (LEP), but little is known about interpreter use in the hospital. Evaluate interpreter use for clinical encounters in the hospital. Cross-sectional. Hospitalized Spanish and Chinese-speaking LEP patients. Patient reported use of interpreters during hospitalization. Among 234 patients, 57% reported that any kind of interpreter was present with the physician at admission, 60% with physicians during hospitalization, and 37% with nurses since admission. The use of professional interpreters with physicians was infrequent overall (17% at admission and 14% since admission), but even less common for encounters with nurses (4%, p interpreter was more common with physicians (28% at admission, 23% since admission) than with nurses (18%, p = 0.008). Few patients reported that physicians spoke their language well (19% at admission, 12% since admission) and even fewer reported that nurses spoke their language well (6%, p = 0.0001). Patients were more likely to report that they either "got by" without an interpreter or were barely spoken to at all with nurses (38%) than with physicians at admission (14%) or since admission (15%, p Interpreter use varied by type of clinical contact, but was overall more common with physicians than with nurses. Professional interpreters were rarely used. With physicians, use of ad hoc interpreters such as family or friends was most common; with nurses, patients often reported, "getting by" without an interpreter or barely speaking at all.

    We surveyed New Jersey (NJ) hospitals to assess current language services and identify policy recommendations on meeting limited English proficiency (LEP) patients' needs. Survey with 37 questions regarding hospital/patient features, interpreter services, and resources/policies needed to provide quality interpreter services. Sixty-seven hospitals responded (55% response rate). Most NJ hospitals have no interpreter services department, 80% provide no staff training on working with interpreters, 31% lack multilingual signs, and 19% offer no written translation services. Only 3% of hospitals have full-time interpreters, a ratio of 1 interpreter:240,748 LEP NJ residents. Most hospitals stated third-party reimbursement for interpreters would be beneficial, by reducing costs, adding interpreters, meeting population growth, and improving communication. Most NJ hospitals have no full-time interpreters, interpreter services department, or staff training on working with interpreters, and deficiencies exist in hospital signage and translation services. Most NJ hospitals stated third-party reimbursement for interpreter services would be beneficial.

    Directory of Open Access Journals (Sweden)

    Pishkova Elena Jurievna


    Full Text Available This article is devoted to the problems which students are facing while mastering the skills of a simultaneous interpreting. The article offers a number of exercises to help solve these problems. The authors underline that it is hardly possible to prepare professional simultaneous interpreters among undergraduates for some reasons, and above all because of insufficient time and absence of technical equipment. Nevertheless, the authors conclude by stating the importance of systematic development of students' perceptive skills, attention, memory and reaction required for providing simultaneous interpreting. The main difficulties in simultaneous interpreting training can be connected with three stages of interpreting: listening, comprehension and speaking. Listening challenges deal with a bad speaker’s pronunciation, some technical problems, as well as regional accents or pigeons. As for comprehension problems they are usually connected with the fact that the interpreter isn’t well grounded in the discussion topic, or he isn’t good at topic terminology. It stands to reason that a well-skilled interpreter should prepare to the interpreting topic beforehand. Speaking difficulties can be connected with a poor interpreter’s pronunciation, often caused a stress factor and a lack of topic knowledge. As a rule an excellent pronunciation, a good articulation and a trained voice are necessary for a professional interpreter. The main principal of training exercises given in this article covers all interpreting difficulties mentioned above.

  3. The emergent Copenhagen interpretation of quantum mechanics (United States)

    Hollowood, Timothy J.


    We introduce a new and conceptually simple interpretation of quantum mechanics based on reduced density matrices of sub-systems from which the standard Copenhagen interpretation emerges as an effective description of macroscopically large systems. This interpretation describes a world in which definite measurement results are obtained with probabilities that reproduce the Born rule. Wave function collapse is seen to be a useful but fundamentally unnecessary piece of prudent book keeping which is only valid for macro-systems. The new interpretation lies in a class of modal interpretations in that it applies to quantum systems that interact with a much larger environment. However, we show that it does not suffer from the problems that have plagued similar modal interpretations like macroscopic superpositions and rapid flipping between macroscopically distinct states. We describe how the interpretation fits neatly together with fully quantum formulations of statistical mechanics and that a measurement process can be viewed as a process of ergodicity breaking analogous to a phase transition. The key feature of the new interpretation is that joint probabilities for the ergodic subsets of states of disjoint macro-systems only arise as emergent quantities. Finally we give an account of the EPR-Bohm thought experiment and show that the interpretation implies the violation of the Bell inequality characteristic of quantum mechanics but in a way that is rather novel. The final conclusion is that the Copenhagen interpretation gives a completely satisfactory phenomenology of macro-systems interacting with micro-systems.

  4. Interpret teaching and teach interpreting: positions assumed in the interpretative act in mainstream contexts for deaf people

    Directory of Open Access Journals (Sweden)

    Audrei Gesser


    Full Text Available The goal of this article is to present some descriptions about the educational interpreter performance in the context of a mainstream school, more specifically in the 7th grade with four deaf students included, in which a bilingual project has being carried out. Relying on the assumption that inclusion forces interpreters to activate pedagogical practices during the interpretative act, this investigation payed attention to two phenomena: by one hand, the constructions of temporal spaces in the classroom that claim ties and partnerships between interpreters and teachers, beyond the technical interpretation itself. By the other hand, the configurations regarding interpretative decisions making emerged from pedagogical happenings. The data analysis indicates that there is a switch between the “interpreter-positon” and the “master-position”, being the last activated by the interpreter inner desire in creating ties and connections with deaf students in their learning process; and the former position, as an effect of the interpreter´s own challenges faced daily, in linguistic, cognitive, referential, and physical terms.

  6. Language interpreter utilization in the emergency department setting: a clinical review. (United States)

    Ramirez, Dorian; Engel, Kirsten G; Tang, Tricia S


    The emergency department (ED) serves as the entry point into the U.S. health care system for many patients with limited English proficiency (LEP). This paper reviews the literature on language interpreter utilization in the ED setting. We focused on three clinical issues related to professional language interpretation: (1) patient satisfaction, (2) health care delivery, and (3) current interpreter utilization practices. Compared with-English speaking patients, LEP patients report less satisfaction with medical encounters, have different rates of diagnostic testing, and receive less explanation and follow-up. Although professional interpretation has been associated with improvements in patient satisfaction, communication, and health care access, these services are largely under-utilized in ED settings. Reliance on untrained ad hoc interpreters, perceived time and labor associated with obtaining and working with an interpreter, and costs of implementing professional interpreter services serve as barriers to implementation and utilization.

  7. Interpretation of Services Marketing Concepts


    Kauppinen-Räisänen, Hannele; Grönroos, Christian; Gummerus, Johanna


    Scholarly research has produced conceptual knowledge that is based on real-life marketing phenomena. An initial aim of past research has been to produce marketing knowledge as a base for efficient business operation and for the improvement of productivity. Thus, an assumption has been that the knowledge would be applied by organisations. This study focuses on understanding the use of marketing knowledge within the field of service marketing. Hence, even if marketing knowledge about service-or...

  8. Informal interpreting in general practice: Comparing the perspectives of general practitioners, migrant patients and family interpreters. (United States)

    Zendedel, Rena; Schouten, Barbara C; van Weert, Julia C M; van den Putte, Bas


    To explore differences in perspectives of general practitioners, Turkish-Dutch migrant patients and family interpreters on interpreters' role, power dynamics and trust in interpreted GP consultations. 54 semi-structured in-depth interviews were conducted with the three parties focusing on interpreter's role, power and trust in interpreters. In line with family interpreters' perspective, patients expected the interpreters to advocate on their behalf and felt empowered when they did so. GPs, on the contrary, felt annoyed and disempowered when the family interpreters performed the advocacy role. Family interpreters were trusted by patients for their fidelity, that is, patients assumed that family interpreters would act in their best interest. GPs, on the contrary, mistrusted family interpreters when they perceived dishonesty or a lack of competence. Opposing views were found between GPs on the one hand and family interpreters and patients on the other hand on interpreter's role, power dynamics and the different dimensions of trust. These opposing perspectives might lead to miscommunication and conflicts between the three interlocutors. GPs should be educated to become aware of the difficulties of family interpreting, such as conflicting role expectations, and be trained to be able to call on professional interpreters when needed.

  9. An information gap in DNA evidence interpretation.

    Directory of Open Access Journals (Sweden)

    Mark W Perlin

    Full Text Available Forensic DNA evidence often contains mixtures of multiple contributors, or is present in low template amounts. The resulting data signals may appear to be relatively uninformative when interpreted using qualitative inclusion-based methods. However, these same data can yield greater identification information when interpreted by computer using quantitative data-modeling methods. This study applies both qualitative and quantitative interpretation methods to a well-characterized DNA mixture and dilution data set, and compares the inferred match information. The results show that qualitative interpretation loses identification power at low culprit DNA quantities (below 100 pg, but that quantitative methods produce useful information down into the 10 pg range. Thus there is a ten-fold information gap that separates the qualitative and quantitative DNA mixture interpretation approaches. With low quantities of culprit DNA (10 pg to 100 pg, computer-based quantitative interpretation provides greater match sensitivity.

    The design of a syntax-directed interpreter for a subset of Algol is described. It is a conceptual design with sufficient details and completeness but as much independence of implementation as possible. The design includes a detailed description of a scanner, an analyzer described in the Floyd-Evans productions, a hash-coded symbol table, and an executor. Interpretation of sample programs is also provided to show how the interpreter functions.

  11. A Very Short Self-Interpreter


    Mazonka, Oleg; Cristofani, Daniel B.


    In this paper we would like to present a very short (possibly the shortest) self-interpreter, based on a simplistic Turing-complete imperative language. This interpreter explicitly processes the statements of the language, which means the interpreter constitutes a description of the language inside that same language. The paper does not require any specific knowledge; however, experience in programming and a vivid imagination are beneficial.

  12. System-level factors affecting clinicians' perceptions and use of interpreter services in California public hospitals. (United States)

    Baurer, Danielle; Yonek, Julie C; Cohen, Alan B; Restuccia, Joseph D; Hasnain-Wynia, Romana


    Professional language interpreters are skilled in the nuances of interpretation and are less likely to make errors of clinical significance but clinicians infrequently use them. We examine system-level factors that may shape clinicians' perceptions and use of professional interpreters. Exploratory qualitative study in 12 California public hospitals. We conducted in-person key informant interviews with hospital leadership, clinical staff, and administrative staff. Five emergent themes highlight system-level factors that may influence clinicians' perceptions and use of professional interpreters in hospitals: (1) organization-wide commitment to improving language access for LEP patients; (2) organizational investment in remote interpreter technologies to increase language access; (3)training clinicians on how to access and work with interpreters; (4) hospital supports the training and certification of bilingual staff to serve as interpreters to expand in-person, on-site, interpreter capacity; and (5)organizational investment in readily accessible telephonic interpretation. Multiple system-level factors underlie clinicians' use of professional interpreters. Interventions that target these factors could improve language services for patients with limited English proficiency.

  13. Mind, Matter, Information and Quantum Interpretations

    Directory of Open Access Journals (Sweden)

    Reza Maleeh


    Full Text Available In this paper I give a new information-theoretic analysis of the formalisms and interpretations of quantum mechanics (QM in general, and of two mainstream interpretations of quantum mechanics in particular: The Copenhagen interpretation and David Bohm’s interpretation of quantum mechanics. Adopting Juan G. Roederer’s reading of the notion of pragmatic information, I argue that pragmatic information is not applicable to the Copenhagen interpretation since the interpretation is primarily concerned with epistemology rather than ontology. However it perfectly fits Bohm’s ontological interpretation of quantum mechanics in the realms of biotic and artificial systems. Viewing Bohm’s interpretation of QM in the context of pragmatic information imposes serious limitations to the qualitative aspect of such an interpretation, making his extension of the notion active information to every level of reality illegitimate. Such limitations lead to the idea that, contrary to Bohm’s claim, mind is not a more subtle aspect of reality via the quantum potential as active information, but the quantum potential as it affects particles in the double-slit experiment represents the non-algorithmic aspect of the mind as a genuine information processing system. This will provide an information-based ground, firstly, for refreshing our views on quantum interpretations and secondly, for a novel qualitative theory of the relationship of mind and matter in which mind-like properties are exclusive attributes of living systems. To this end, I will also take an information-theoretic approach to the notion of intentionality as interpreted by John Searle.

  14. Geophysical interpretation using integral equations

    CERN Document Server

    Eskola, L


    Along with the general development of numerical methods in pure and applied to apply integral equations to geophysical modelling has sciences, the ability improved considerably within the last thirty years or so. This is due to the successful derivation of integral equations that are applicable to the modelling of complex structures, and efficient numerical algorithms for their solution. A significant stimulus for this development has been the advent of fast digital computers. The purpose of this book is to give an idea of the principles by which boundary-value problems describing geophysical models can be converted into integral equations. The end results are the integral formulas and integral equations that form the theoretical framework for practical applications. The details of mathematical analysis have been kept to a minimum. Numerical algorithms are discussed only in connection with some illustrative examples involving well-documented numerical modelling results. The reader is assu­ med to have a back...

    DEFF Research Database (Denmark)

    Lauritzen, Steffen Lilholt; Richardson, Thomas S.


    Chain graphs are a natural generalization of directed acyclic graphs and undirected graphs. However, the apparent simplicity of chain graphs belies the subtlety of the conditional independence hypotheses that they represent. There are many simple and apparently plausible, but ultimately fallacious......, interpretations of chain graphs that are often invoked, implicitly or explicitly. These interpretations also lead to flawed methods for applying background knowledge to model selection. We present a valid interpretation by showing how the distribution corresponding to a chain graph may be generated from...... the equilibrium distributions of dynamic models with feed-back. These dynamic interpretations lead to a simple theory of intervention, extending the theory developed for directed acyclic graphs. Finally, we contrast chain graph models under this interpretation with simultaneous equation models which have...

  14. Integrating Emotions Into the Critical Interpretive Synthesis. (United States)

    McFerran, Katrina Skewes; Hense, Cherry; Medcalf, Laura; Murphy, Melissa; Fairchild, Rebecca


    Critical interpretive synthesis is a particular form of systematic review that critically examines the decisions made by authors while conducting and publishing about their research and practices. It differs from empirical syntheses of qualitative research by emphasizing the interpreted and constructed nature of this form of secondary analysis. In this article, we extend previous literature on critical interpretive syntheses by highlighting the integration of emotional responses when developing critical questions for interrogating the literature and interpreting results. Our extension of the critical interpretive synthesis is illustrated through examples from five studies examining literature in our own field of music therapy, as well as related fields of disability studies, mental health, music psychology, and child welfare. The methodology we have refined uses an iterative and recursive method that promotes increased critical awareness of the assumptions driving the production of research in health contexts. © The Author(s) 2016.

  15. Migrant General Practitioners' Experiences of Using Interpreters in Health-care: a Qualitative Explorative Study. (United States)

    Krupic, Ferid; Samuelsson, Kristian; Fatahi, Nabi; Skoldenberg, Olof; Sayed-Noor, Arkan S


    According to the UNHCR, 250 million people currently live outside their country of birth. The growing multicultural population poses a major challenge to healthcare professionals who aim to provide individualized, holistic care, which respects the individual's autonomy. To ensure basic rights, healthcare interventions should be guided by the value of benefiting others; individuals should be treated honestly, equally, and impartially. To investigate immigrant doctors' experiences of using interpreters in the Swedish health-care system. Twenty-eight doctors, 12 men and 16 women from Bosnia and Herzegovina, Croatia, Macedonia and Serbia participated in four focus group interviews (FGI). The interviews were audio recorded, transcribed and analyzed using content analysis method. The best results in the present study were achieved in situations where a professional interpreter was involved. In some cases, the doctors were forced to use relatives or a colleague to interpret, which in many cases proved to be a mistake. The consequences of poor interpretation routines included payment by mistake, a patient paying an interpreter who refused to interpret, time spent waiting for another interpreter, as well as disturbances to the daily work schedule. Finding someone who could replace an interpreter who did not show up caused time shortage and increased stress. Improved routines and more effective cooperation between interpreting services and health-care centers are needed in order to ensure that using professional interpreters guarantees appropriate, high quality care. Improvements are needed to provide satisfactory health-care to people with limited language skills. In order to achieve this, better education of interpreters is needed, especially regarding cultural diversity and medical terminology. These improvements present complex challenges, deserving empirical and critical reflection in order to improve the work situation for doctors.

  16. The logical interpretation and the measurement problem (United States)

    Vuletic, Mark I.

    The measurement problem is one of the two key problems in the foundations of quantum mechanics, carrying with it the seeming implication that instead of the familiar definite states of affairs we think we experience, there typically should exist only phenomenologically ill-defined "superpositions" of such states of affairs. Dissatisfaction with this implication has led to the development of many wildly different interpretations of quantum mechanics, positing everything from pilot waves to splitting universes. A recent tradition of interpretation draws heavily upon decoherence and a "consistent histories" formalism to try to resolve the standard conceptual problems of quantum mechanics. Roland Omnes, one physicist in this tradition, argues that his own "logical interpretation" resolves every paradox and conceptual difficulty raised by quantum mechanics, except for what he calls the "objectification problem." Figuring out what relation the objectification problem has to the measurement problem, and, more generally, what the logical interpretation has to say about the measurement problem, turns out to be very difficult, even with the benefit of correspondence. In my dissertation, I have tried to narrow down the possibilities for what Omnes might have in mind with respect to the measurement problem, and considered whether any of these constitutes an advance over what came before. I conclude that there are two plausible possibilities: either (i) an overly aggressive pragmatic spirit has caused Omnes to fail to even realize that a critical part of the measurement problem exists, or (ii) the logical interpretation is best understood as offering a stochastic hidden factor interpretation, with complementarity operating at the level of the hidden factors, even though Omnes himself would resist describing the logical interpretation in this way. I also conclude that the logical interpretation, far from saving classical logic, actually undermines it. While this may not

    Andriole, Katherine P.; Morin, Richard L.; Arenson, Ronald L.; Carrino, John A.; Erickson, Bradley J.; Horii, Steven C.; Piraino, David W.; Reiner, Bruce I.; Seibert, James A.; Siegel, Eliot L.


    The Society for Computer Applications in Radiology (SCAR) Transforming the Radiological Interpretation Process (TRIP) Initiative aims to spearhead research, education, and discovery of innovative solutions to address the problem of information and image data overload. The initiative will foster inter-disciplinary research on technological, environmental and human factors to better manage and exploit the massive amounts of data. TRIP will focus on the following basic objectives: improving the efficiency of interpretation of large data sets, improving the timeliness and effectiveness of communication, and decreasing medical errors. The ultimate goal of the initiative is to improve the quality and safety of patient care. Interdisciplinary research into several broad areas will be necessary to make progress in managing the ever-increasing volume of data. The six concepts involved include: human perception, image processing and computer-aided detection (CAD), visualization, navigation and usability, databases and integration, and evaluation and validation of methods and performance. The result of this transformation will affect several key processes in radiology, including image interpretation; communication of imaging results; workflow and efficiency within the health care enterprise; diagnostic accuracy and a reduction in medical errors; and, ultimately, the overall quality of care.

  20. The psychotherapist and the sign language interpreter. (United States)

    de Bruin, Ed; Brugmans, Petra


    Specialized psychotherapy for deaf people in the Dutch and Western European mental health systems is still a rather young specialism. A key policy principle in Dutch mental health care for the deaf is that they should receive treatment in the language most accessible to them, which is usually Dutch Sign Language (Nederlandse Gebarentaal or NGT). Although psychotherapists for the deaf are trained to use sign language, situations will always arise in which a sign language interpreter is needed. Most psychotherapists have the opinion that working with a sign language interpreter in therapy sessions can be a valuable alternative option but also see it as a second-best solution because of its impact on the therapeutic process. This paper describes our years of collaborationship as a therapist and a sign language interpreter. If this collaborationship is optimal, it can generate a certain "therapeutic power" in the therapy sessions. Achieving this depends largely on the interplay between the therapist and the interpreter, which in our case is the result of literature research and our experiences during the last 17 years. We analyze this special collaborative relationship, which has several dimensions and recurrent themes like, the role conception of the interpreter, situational interpreting, organizing the interpretation setting, or managing therapeutic phenomena during therapy sessions.

  1. The Future Of Court Interpreting In Croatia

    Directory of Open Access Journals (Sweden)

    Dobrić Katja


    Full Text Available Court interpreting in Croatia is a very unregulated field especially regarding the training and the skills that are to be acquired in order to pro- vide accurate translation at courts. One of the prerequisites according to the Regulations on Court Interpreters in Croatia is knowledge of the structure of judicial power, state government and legal terminology. Although the Regulations prescribe that the training should last no longer than two months, the organisations providing such training shorten this to three or four days. Taking into account all that has been said one realizes that in such short time a per- son cannot be properly qualified to practice as a court interpreter. According to the EU Directive on the right to interpretation and translation in criminal proceedings member states should provide adequate training in order to ensure the quality of interpretation and to avoid that suspected or accused persons complain that the quality of interpretation was not good enough to secure the fairness of the proceeding, which according to Article 2 of the Directive they have the right to. Since Croatia joined the European Union on 1 July 2013, it will have to change its Regulations on Court Interpreters in order to com- ply with this Directive. This paper will try to analyze the problems within the scope of court interpreter’s profession in Croatia both in civil and in criminal proceedings. Several examples will be suggested as the possible model for modifying court interpreting in Croatia. Since this profession is often underrated by the national courts, the paper will suggest ways to prevent such views and point out the importance of good court interpretation

  2. Working with the Hmong Population in a Genetics Setting: an Interpreter Perspective. (United States)

    Krieger, Meghan; Agather, Aime; Douglass, Kathryn; Reiser, Catherine A; Petty, Elizabeth M


    The aim of this pilot qualitative study was to describe the experiences and beliefs of medical interpreters when working with genetic counselors and other genetic providers caring for Hmong patients who are not native English speakers. Specific goals were to identify interpreters' thoughts and perceptions on (a) their roles during sessions, (b) unique challenges in a genetics session, (c) knowledge genetics providers need when working with Hmong patients and interpreters, and (d) supports and training needed to effectively interpret in a genetics setting. Hmong medical interpreters from Wisconsin and Minnesota were invited by email to participate in the study. Six were interviewed by telephone. Participants had worked with a variety of providers including geneticists, genetic counselors, primary care physicians, and oncologists. Factors identified by Hmong interpreters that made interpretation of content difficult in clinical genetics sessions included: time constraints, technical terms, and unique cultural perspectives of Hmong patients. While all respondents felt their primary role was to interpret session content as close to verbatim as possible, there was notable variation in the description of their interpretation style and other perceived roles in the genetic counseling session. Cultural issues genetics providers could consider when working with Hmong patients and different style issues when working with Hmong interpreters are discussed. Ideas for future studies and suggestions to improve communication with Hmong patients are explored.

In 2008, 3688 patients (4223 serum samples) were tested by enzyme immunoassay (EIA), with 832 patients tested by confirmatory in-house IgG Western blot: 272 patients were Western blot-positive, 170 were weak positive, 156 were equivocal and 234 were negative. These results were assessed, and a review of interpretation criteria from both the USA and Europe was carried out. New interpretation criteria and a testing algorithm were developed. The revised criteria changed the results in 109/3688 (3%) patients and produced significantly more Western blot-positive and weak-positive patients than with the current criteria (485 vs. 442, P blot interpretation and improved the sensitivity and robustness of their Western blot method. Using a protocol tailored to patients that incorporates clinical characteristics means that the entire process will be easier and will aid the management of patients.

  5. Interpreting BOLD: towards a dialogue between cognitive and cellular neuroscience. (United States)

    Hall, Catherine N; Howarth, Clare; Kurth-Nelson, Zebulun; Mishra, Anusha


    Cognitive neuroscience depends on the use of blood oxygenation level-dependent (BOLD) functional magnetic resonance imaging (fMRI) to probe brain function. Although commonly used as a surrogate measure of neuronal activity, BOLD signals actually reflect changes in brain blood oxygenation. Understanding the mechanisms linking neuronal activity to vascular perfusion is, therefore, critical in interpreting BOLD. Advances in cellular neuroscience demonstrating differences in this neurovascular relationship in different brain regions, conditions or pathologies are often not accounted for when interpreting BOLD. Meanwhile, within cognitive neuroscience, the increasing use of high magnetic field strengths and the development of model-based tasks and analyses have broadened the capability of BOLD signals to inform us about the underlying neuronal activity, but these methods are less well understood by cellular neuroscientists. In 2016, a Royal Society Theo Murphy Meeting brought scientists from the two communities together to discuss these issues. Here, we consolidate the main conclusions arising from that meeting. We discuss areas of consensus about what BOLD fMRI can tell us about underlying neuronal activity, and how advanced modelling techniques have improved our ability to use and interpret BOLD. We also highlight areas of controversy in understanding BOLD and suggest research directions required to resolve these issues.This article is part of the themed issue 'Interpreting BOLD: a dialogue between cognitive and cellular neuroscience'. © 2016 The Author(s).

  6. The formal verification of generic interpreters (United States)

    Windley, P.; Levitt, K.; Cohen, G. C.


    The task assignment 3 of the design and validation of digital flight control systems suitable for fly-by-wire applications is studied. Task 3 is associated with formal verification of embedded systems. In particular, results are presented that provide a methodological approach to microprocessor verification. A hierarchical decomposition strategy for specifying microprocessors is also presented. A theory of generic interpreters is presented that can be used to model microprocessor behavior. The generic interpreter theory abstracts away the details of instruction functionality, leaving a general model of what an interpreter does.

  7. Principles of interpretation, tourism and heritage interpretation – the experience of Romanian museums

    Directory of Open Access Journals (Sweden)

    Daniela Dumbraveanu


    Full Text Available This paper aims to present a generic theoretical framework related to interpretation as a field of study focusing on tourism interpretation and heritage interpretation. It primarily focuses on discussing the international evolution of this field and the principles of interpretation as presented by their author, Freeman Tilden. Secondly, the paper attempts to analyze to what extent modern interpretation is experienced in Romania by means of two relevant case studies selected. The two case studies selected are significant and symbolic institutions within their system, well known and internationally visited: the Peasant Museum in Bucharest and the Memorial to the Victims of Communism and to the Resistance in Sighetu Marmatiei. Thirdly, the paper draws a broader picture showing whether the principles of interpretation and heritage interpretation are familiar to Romanian museums and to what extent they are in use.

  8. Interpreting at the End of Life: A Systematic Review of the Impact of Interpreters on the Delivery of Palliative Care Services to Cancer Patients with Limited English Proficiency (United States)

    Silva, Milagros D.; Genoff, Margaux; Zaballa, Alexandra; Jewell, Sarah; Stabler, Stacy; Gany, Francesca M.; Diamond, Lisa C.


    Context Language barriers can influence the health quality and outcomes of Limited English Poficiency (LEP) patients at end of life, including symptom assessment and utilization of hospice services. Objective To determine how professional medical interpreters influence the delivery of palliative care services to LEP patients. Methods We conducted a systematic review of the literature in all available languages of six databases from 1966 to 2014. Studies evaluated use of language services for LEP patients who received palliative care services. Data were abstracted from ten articles and collected on study design, size, comparison groups, outcomes and interpreter characteristics. Results Six qualitative and four quantitative studies assessed the use of interpreters in palliative care. All studies found that the quality of care provided to LEP patients receiving palliative services is influenced by the type of interpreter used. When professional interpreters were not used, LEP patients and families had inadequate understanding about diagnosis and prognosis during goals of care conversations, and patients had worse symptom management at the end of life, including pain and anxiety. Half of the studies concluded that professional interpreters were not utilized adequately and several suggested that pre-meetings between clinicians and interpreters were important to discuss topics and terminology to be used during goals of care discussions. Conclusion LEP patients had worse quality of end-of-life care and goals of care discussions when professional interpreters were not used. More intervention studies are needed to improve the quality of care provided to LEP patients and families receiving palliative services. PMID:26549596

  9. Interpretation of ambiguous information in clinical depression. (United States)

    Mogg, Karin; Bradbury, Katherine E; Bradley, Brendan P


    The present study used two cognitive tasks--a text comprehension task and a homophone task--to investigate whether clinically depressed individuals have a negative bias when interpreting ambiguous information. Previous research indicates that both tasks are sensitive to anxiety-related interpretive biases, and that the former is less prone to response bias effects. Negative memory biases were also assessed. Results showed that, compared with normal controls, depressed individuals made more negative interpretations on the homophone task, and they also showed an enhanced negative recall bias. However, the groups did not differ in interpretative bias on the text comprehension task. Possible explanations of the results are discussed, including the potential influences of self-referent processing and response bias.

  10. Interpreters' notes. On the choice of language

    DEFF Research Database (Denmark)

    Dam, Helle Vrønning


    This paper reports on a small-scale empirical study on note-taking in consecutive interpreting. As data, the study draws on the notes produced by four subjects while interpreting one Spanish source text consecutively into Danish, on the one hand, and one Danish source text into Spanish......, on the other. The aim of the study is to explore what governs conference interpreters' choice of language for their notes. The categories traditionally used to discuss, describe and explain this choice are those of 'source language' and 'target language', and these categories are therefore subject...... to particular scrutiny here. However, somewhat surprisingly, the results of the analyses indicate that the choice of language in note-taking is governed mainly by the status of the language in the interpreters' language combination, i.e. whether it is an A- or a B-language, and much less by its status...

  11. [The professional interpreter disappears: quality is jeopardized]. (United States)

    Langendijk-van den Berg, Irene; Verdonk, Petra; Abma, Tineke


    According to Dutch law, patients have the right to comprehensible communication. However, professional interpreters are not being used sufficiently: health care providers often do not recognize when language barriers interfere with comprehension. The use of professional interpreters declined even further when the Dutch government withdrew its funding for medical interpreters in January 2012. Additionally, the government's stance that non-native speakers have to master the language and organize translating help when needed seems to have given a signal to health care providers that this is not their responsibility. Nonetheless, health care providers are obliged by law to provide comprehensible information. Therefore, it is important to provide proper training so they can recognize language barriers and know when a professional interpreter is necessary. In addition, a financial aid system needs to be developed for those patients who cannot reasonably be expected to have mastered the language.

  15. Applied photo interpretation for airbrush cartography (United States)

    Inge, J. L.; Bridges, P. M.


    New techniques of cartographic portrayal have been developed for the compilation of maps of lunar and planetary surfaces. Conventional photo interpretation methods utilizing size, shape, shadow, tone, pattern, and texture are applied to computer processed satellite television images. The variety of the image data allows the illustrator to interpret image details by inter-comparison and intra-comparison of photographs. Comparative judgements are affected by illumination, resolution, variations in surface coloration, and transmission or processing artifacts. The validity of the interpretation process is tested by making a representational drawing by an airbrush portrayal technique. Production controls insure the consistency of a map series. Photo interpretive cartographic portrayal skills are used to prepare two kinds of map series and are adaptable to map products of different kinds and purposes.

  16. Abstract Interpretation as a Programming Language

    Directory of Open Access Journals (Sweden)

    Mads Rosendahl


    Full Text Available In David Schmidt's PhD work he explored the use of denotational semantics as a programming language. It was part of an effort to not only treat formal semantics as specifications but also as interpreters and input to compiler generators. The semantics itself can be seen as a program and one may examine different programming styles and ways to represent states. Abstract interpretation is primarily a technique for derivation and specification of program analysis. As with denotational semantics we may also view abstract interpretations as programs and examine the implementation. The main focus in this paper is to show that results from higher-order strictness analysis may be used more generally as fixpoint operators for higher-order functions over lattices and thus provide a technique for immediate implementation of a large class of abstract interpretations. Furthermore, it may be seen as a programming paradigm and be used to write programs in a circular style.

  1. Revolutionizing volunteer interpreter services: an evaluation of an innovative medical interpreter education program. (United States)

    Hasbún Avalos, Oswaldo; Pennington, Kaylin; Osterberg, Lars


    In our ever-increasingly multicultural, multilingual society, medical interpreters serve an important role in the provision of care. Though it is known that using untrained interpreters leads to decreased quality of care for limited English proficiency patients, because of a short supply of professionals and a lack of formalized, feasible education programs for volunteers, community health centers and internal medicine practices continue to rely on untrained interpreters. To develop and formally evaluate a novel medical interpreter education program that encompasses major tenets of interpretation, tailored to the needs of volunteer medical interpreters. One-armed, quasi-experimental retro-pre-post study using survey ratings and feedback correlated by assessment scores to determine educational intervention effects. Thirty-eight students; 24 Spanish, nine Mandarin, and five Vietnamese. The majority had prior interpreting experience but no formal medical interpreter training. Students completed retrospective pre-test and post-test surveys measuring confidence in and perceived knowledge of key skills of interpretation. Primary outcome measures were a 10-point Likert scale for survey questions of knowledge, skills, and confidence, written and oral assessments of interpreter skills, and qualitative evidence of newfound knowledge in written reflections. Analyses showed a statistically significant (P  0.8). The second half of the program was also quantitatively and qualitatively shown to be a vital learning experience, resulting in 18 % more students passing the oral assessments; a 19 % increase in mean scores for written assessments; and a newfound understanding of interpreter roles and ways to navigate them. This innovative program was successful in increasing volunteer interpreters' skills and knowledge of interpretation, as well as confidence in own abilities. Additionally, the program effectively taught how to navigate the roles of the interpreter to maintain

  2. Users’ Quality Expectations in Conference Interpreting

    Directory of Open Access Journals (Sweden)

    Mansour Amini


    Full Text Available This paper is part of an unpublished doctoral thesis on “Conference Interpreting in Malaysia”. Expectations of users were explored by an on-site questionnaire-based survey study in Malaysian conference interpreting setting. The relative importance of various linguistic and non-linguistic criteria for quality was obtained through quantitative and qualitative methods of data collection. A reliable sample of 256 interpreting “users” (Cronbach alpha coefficient=0.81 were collected from five international conferences in Malaysia. Analysis of the results revealed that users attached high value to the linguistic criteria of sense-consistency with original message (94.1%, logical cohesion (91.1%, fluency of delivery (91%, correct terminology (89.8%, correct grammar (82.8%, completeness of interpretation (80.2%, synchronicity (73%, and style (70.5% rating the criteria very important or important. The parameters of pleasant voice (60.9%, lively intonation (60.4%, and native accent (57.3% were considered desirable, but not essential as they received the least importance by the users. Findings from the open-ended questions showed that users consider “wide range of topics” and “broadening one’s horizons” as the most interesting aspects of conference interpreting. Users indicated that they were willing to listen to the interpretation even if they understood it. These suggest that interpreters are seen as a professional source of knowledge from users’ perspectives. While stressing on the linguistic aspects and the importance of output-related quality criteria, the researcher calls for taking further notice of situational particularities and background variables, pragmatic communication issues, and contextual features with a more extensive view of the profession, in addition to the methodological issues that have always been argued in interpreting quality research.

  5. Cling - The LLVM-based C++ Interpreter

    CERN Multimedia

    CERN. Geneva


    Cling ( is a C++ interpreter, built on top of clang ( and LLVM ( Like its predecessor CINT, cling offers an interactive, terminal-like prompt. It enables exploratory programming with rapid edit / run cycles. The ROOT team has more than 15 years of experience with C++ interpreters, and this has been fully exploited in the design of cling. However, matching the concepts of an interpreter to a compiler library is a non-trivial task; we will explain how this is done for cling, and how we managed to implement cling as a small (10,000 lines of code) extension to the clang and llvm libraries. The resulting features clearly show the advantages of basing an interpreter on a compiler. Cling uses clang's praised concise and easy to understand diagnostics. Building an interpreter on top of a compiler library makes the transition between interpreted and compiled code much easier and smoother. We will present the design, e.g. how cling treats the C++ extensions ...

  6. A bird's eye view: the cognitive strategies of experts interpreting seismic profiles (United States)

    Bond, C. E.; Butler, R.


    Geoscience is perhaps unique in its reliance on incomplete datasets and building knowledge from their interpretation. This interpretation basis for the science is fundamental at all levels; from creation of a geological map to interpretation of remotely sensed data. To teach and understand better the uncertainties in dealing with incomplete data we need to understand the strategies individual practitioners deploy that make them effective interpreters. The nature of interpretation is such that the interpreter needs to use their cognitive ability in the analysis of the data to propose a sensible solution in their final output that is both consistent not only with the original data but also with other knowledge and understanding. In a series of experiments Bond et al. (2007, 2008, 2011, 2012) investigated the strategies and pitfalls of expert and non-expert interpretation of seismic images. These studies focused on large numbers of participants to provide a statistically sound basis for analysis of the results. The outcome of these experiments showed that techniques and strategies are more important than expert knowledge per se in developing successful interpretations. Experts are successful because of their application of these techniques. In a new set of experiments we have focused on a small number of experts to determine how they use their cognitive and reasoning skills, in the interpretation of 2D seismic profiles. Live video and practitioner commentary were used to track the evolving interpretation and to gain insight on their decision processes. The outputs of the study allow us to create an educational resource of expert interpretation through online video footage and commentary with associated further interpretation and analysis of the techniques and strategies employed. This resource will be of use to undergraduate, post-graduate, industry and academic professionals seeking to improve their seismic interpretation skills, develop reasoning strategies for

    Andrew Coan


    Full Text Available The extreme difficulty of amending the U.S. Constitution plays a central but largely unexamined role in theoretical debates over interpretive choice. In particular, conventional wisdom assumes that the extreme difficulty of Article V amendment weakens the case for originalism. This view might ultimately be correct, but it is not the freestanding argument against originalism it is often presumed to be. Rather, it depends on contestable normative and empirical premises that require defense. If those premises are wrong, the stringency of Article V might actually strengthen the case for originalism. Or Article V might have no impact on that case one way or another. This “complexity thesis” highlights and clarifies the role that difficulty of amendment plays across a range of significant interpretive debates, including those surrounding writtenness, John Hart Ely’s representation-reinforcement theory, interpretive pluralism, and originalism as a theory of positive law. It also has important implications for the under-studied relations between statutory and constitutional interpretation and federal and state constitutional interpretation.

  8. Interpretive bias, repressive coping, and trait anxiety. (United States)

    Walsh, James J; McNally, Maria A; Skariah, Ancy; Butt, Ayesha A; Eysenck, Michael W


    According to vigilance-avoidance theory, repressors have an avoidant interpretive bias, i.e., they interpret ambiguous self-relevant situations in a nonthreatening fashion. This study sought to demarcate the range of situations associated with avoidant interpretive bias in repressors. Four groups of participants, representing the four combinations of low- and high-trait anxiety and defensiveness, were identified. Those low in trait anxiety and high in defensiveness were categorized as repressors. Participants (N = 163) rated their likelihood of making both threatening and nonthreatening interpretations of 32 ambiguous scenarios over four domains: social, intellectual, physical, and health. Half the scenarios were self-relevant and half were other relevant. Brief measures of state anxiety were taken after each likelihood rating. Repressors displayed an avoidant interpretive bias for ambiguous threats in the social and intellectual domains but not the health or physical domains. This was due to repressors' low level of trait anxiety rather than their high defensiveness. Individuals high in trait anxiety are especially sensitive to situations involving social evaluation but not those characterized by danger to their health or physical well-being.

  10. Developmental levels of processing in metaphor interpretation. (United States)

    Johnson, J; Pascual-Leone, J


    We outline a theory of metaphor interpretation. The theory posits varying levels of semantic processing and formalizes them in terms of kinds of semantic-mapping operators that transform properties of the metaphoric vehicle (i.e., predicate) into properties of the metaphoric topic (i.e., subject). We used cognitive-developmental theory to estimate the mental-processing complexity of the various mapping operators, and thereby to predict the timing of their emergence in childhood, and to construct a measure of the metaphoric-processing levels. Metaphor interpretations collected from children (aged 6-12 years) and adults were coded and scored according to the processing levels. In two separate developmental studies, processing score increased with age in a predictable way. Growth in a mental-attentional resource accounted for much of the developmental variance in metaphor interpretation. Possible moderating effects of knowledge and context are discussed.

  11. Interpretation in Quantum Physics as Hidden Curriculum (United States)

    Baily, Charles; Finkelstein, Noah D.


    Prior research has demonstrated how the realist perspectives of classical physics students can translate into specific beliefs about quantum phenomena when taking an introductory modern physics course. Student beliefs regarding the interpretation of quantum mechanics often vary by context, and are most often in alignment with instructional goals in topic areas where instructors are explicit in promoting a particular perspective. Moreover, students are more likely to maintain realist perspectives in topic areas where instructors are less explicit in addressing interpretive themes, thereby making such issues part of a hidden curriculum. We discuss various approaches to addressing student perspectives and interpretive themes in a modern physics course, and explore the associated impacts on student thinking.

  12. Conversations through barriers of language and interpretation. (United States)

    McCarthy, Jane; Cassidy, Irene; Graham, Margaret M; Tuohy, Dympna

    Ireland has become a multicultural society in just over a decade, with non-Irish nationals comprising 12% of the population. The challenge for nurses working in the Irish healthcare system is to provide culturally appropriate care to this diverse population. This paper reports on a qualitative descriptive study exploring nurses' experiences of communicating with people from diverse cultures, and focuses on language barriers and the use of interpreters. The findings indicate that communicating with people who do not share the same first language is challenging, in particular the participants (nurses) were concerned about their ability to make a comprehensive assessment that ultimately forms the basis for quality care provision. The use of interpreters can inform the assessment process, but there are challenges in accessing and utilising these services. Further continuing education is required to promote culturally appropriate care. There is a need for increased discussion between nurses and interpreters to maximise communication with patients.

  14. Path integral distance for data interpretation

    CERN Document Server

    Volchenkov, D


    The process of data interpretation is always based on the implicit introduction of equivalence relations on the set of walks over the database. Every equivalence relation on the set of walks specifies a Markov chain describing the transitions of a discrete time random walk. In order to geometrize and interpret the data, we propose the new distance between data units defined as a "Feynman path integral", in which all possible paths between any two nodes in a graph model of the data are taken into account, although some paths are more preferable than others. Such a path integral distance approach to the analysis of databases has proven its efficiency and success, especially on multivariate strongly correlated data where other methods fail to detect structural components (urban planning, historical language phylogenies, music, street fashion traits analysis, etc. ). We believe that it would become an invaluable tool for the intelligent complexity reduction and big data interpretation.

    Renograms are currently used for functional assessment by pediatric urologists. The aim of the present work was to focus on the potential pitfalls concerning renography. Potential confounding factors are described in reference to concrete cases. The main types of pitfalls concern venous or urinary catheters and background area definition. Protocols and renogram interpretation are critiqued in a bibliographic review. We propose a technical update and original data on the potential pitfalls in renography interpretation. Multidisciplinary discussion between nuclear medicine, pediatrics and pediatric surgery departments is required before drawing conclusions. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

  17. A Relativistic Symmetrical Interpretation of Quantum Mechanics (United States)

    Heaney, Michael B.

    This poster describes a relativistic symmetrical interpretation (RSI) which postulates: quantum mechanics is intrinsically time-symmetric, with no arrow of time; the fundamental objects of quantum mechanics are transitions; a transition is fully described by a complex transition amplitude density with specified initial and final boundary conditions, and; transition amplitude densities never collapse. This RSI is compared to the Copenhagen Interpretation (CI) for the analysis of Einstein's bubble experiment using both the Dirac and Klein-Gordon equations. The RSI has no zitterbewegung in the particle's rest frame, resolves some inconsistencies of the CI, and gives intuitive explanations of some previously mysterious quantum effects.

  20. Interpreting MARC: Where's the Bibliographic Data?

    Directory of Open Access Journals (Sweden)

    Jason Thomale


    Full Text Available The MARC data format was created early in the history of digital computers. In this article, the author entertains the notion that viewing MARC from a modern technological perspective leads to interpretive problems such as a confusion of "bibliographic data" with "catalog records." He explores this idea through examining a specific MARC interpretation task that he undertook early in his career and then revisited nearly four years later. Revising the code that performed the task confronted him with his own misconceptions about MARC that were rooted in his worldview about what he thought "structured data" should be and helped him to place MARC in a more appropriate context.

  1. Two interpretive systems for natural language? (United States)

    Frazier, Lyn


    It is proposed that humans have available to them two systems for interpreting natural language. One system is familiar from formal semantics. It is a type based system that pairs a syntactic form with its interpretation using grammatical rules of composition. This system delivers both plausible and implausible meanings. The other proposed system is one that uses the grammar together with knowledge of how the human production system works. It is token based and only delivers plausible meanings, including meanings based on a repaired input when the input might have been produced as a speech error.

  2. List search hardware for interpretive software

    CERN Document Server

    Interpreted languages, e.g. BASIC, are simple to learn, easy to use, quick to modify and in general 'user-friendly'. However, a critically time consuming process during interpretation is that of list searching. A special microprogrammed device for fast list searching has therefore been developed at the SPS Division of CERN. It uses bit- sliced hardware. Fast algorithms perform search, insert and delete of a six-character name and its value in a list of up to 1000 pairs. The prototype shows retrieval times of the order of 10-30 microseconds.

  4. Resolving Ambiguity in Emotional Disorders: The Nature and Role of Interpretation Biases. (United States)

    Hirsch, Colette R; Meeten, Frances; Krahé, Charlotte; Reeder, Clare


    People with emotional disorders, such as social anxiety disorder (SAD), generalized anxiety disorder (GAD), and depression, demonstrate a consistent tendency, or bias, to generate negative interpretations of ambiguous material. This is different from people without emotional disorders who tend, in general, to make positive interpretations of ambiguity. If central components of an emotional disorder have high levels of inherent ambiguity (e.g., concern about the negative perceptions of others in SAD, or worry in GAD), then interpretive bias may have a causal maintaining role, and this has been demonstrated in studies using cognitive bias modification techniques. This research has also shown that interpretation biases combine with other cognitive processes, such as imagery and memory, which could exacerbate distress. Psychological interventions will benefit from effectively targeting negative interpretations, and future experimental research can inform ways to improve facilitation of more benign inferential processing to maximize amelioration of key components of emotional disorders.

    Full Text Available Austria had in 1920 Constitutional Court followed by Italy in 1946, Germany in 1949, Romania in 1989, South Africa in 1991, and Ethiopia in 1995. Each Constitution has its provisions on the constitutional interpretation. Romania has its own provisions and it is considered here its legality and the best possible measures and recommendations for future. Judicial power is vested in judiciary to interpret constitution, laws, and actions of other organs of government. Judicial review is the function resulted upon judicial power. Political body joins through the appointment of its members in the judicial review and it limits the independence of judiciary. It also reduces the values of separation of powers. Challenges and opportunities of growth and development do influence the spirit of separation of powers and judicial independence. The principle of inherent judicial power in judiciary inducts upon the constitutional interpretation. Thus, the principles of constitutional interpretation are varying in Romania and other similar constitutional courts of Germany, Ethiopia, and Italy but not in South Africa.

  8. The Copenhagen interpretation as an emergent phenomenon (United States)

    Hollowood, Timothy J.


    The Copenhagen interpretation has been remarkably successful but seems at odds with the underlying linearity of quantum mechanics. We show how it can emerge in a simple way from the underlying microscopic quantum world governed by Schrödinger’s equation without the need for observers or their brains. In order to achieve this, we assemble pieces of various pre-existing ideas. Firstly, we adopt a relational approach and use the eigenvectors of the reduced density matrix of a quantum sub-system, or equivalently the Schmidt decomposition, to define the ‘internal state’ of a sub-system. Previous work has identified serious objections to such an interpretation because it apparently leads to macroscopic superpositions and physically unacceptable instabilities near degeneracies. We show that both these problems are solved if the sub-system consists of a large number of coarse-grained degrees of freedom as one expects in order to make contact with the classical world. We further argue that coarse graining is a necessary ingredient because measuring devices have both finite spatial and temporal resolutions. What results is an interpretation in which both decoherence and coarse graining play key roles and from which the rules of the Copenhagen interpretation are seen to emerge in realistic situations that include the measurement of the position of a particle and a decay process.

  20. Financial Stability: the Problem of Interpretation

    Directory of Open Access Journals (Sweden)

    Romaniak Mykola M.


    Full Text Available The article is concerned with studying the problem of interpretation of the concept of «financial stability», allocating the major groups of approaches to its interpretation and clarifying the reasons for absence of a single uniform definition. On the basis of an analysis, approaches to interpretation of the category of «financial stability» have been divided into three main groups. In the definitions by central banks (the first group emphasis is more often placed upon the matter that a system (not necessarily financial is considered stable if it is able to perform all their functions even under conditions of minor adverse shocks and upheavals. The second way to interpretation – by contradiction – must be taken into consideration in the process of studying the financial stability. According to the third group of views, a system can be considered financially stable until the process of transforming savings into investments remains unbroken. The main reasons for the absence of a single clear formulation of the concept of «financial stability» have been identified, namely: different approaches used by scientists to understanding the content of financial system; refocusing from studying the financial stability towards financial crises; accounting the indicator of financial stability in place of the indicator of financial disturbances. A prospective direction for further research is assessment of financial stability through practical consideration of quantitative characteristics that influence on such stability

  1. The metaphysics of quantum mechanics: Modal interpretations (United States)

    Gluck, Stuart Murray


    This dissertation begins with the argument that a preferred way of doing metaphysics is through philosophy of physics. An understanding of quantum physics is vital to answering questions such as: What counts as an individual object in physical ontology? Is the universe fundamentally indeterministic? Are indiscernibles identical? This study explores how the various modal interpretations of quantum mechanics answer these sorts of questions; modal accounts are one of the two classes of interpretations along with so-called collapse accounts. This study suggests a new alternative within the class of modal views that yields a more plausible ontology, one in which the Principle of the Identity of Indisceribles is necessarily true. Next, it shows that modal interpretations can consistently deny that the universe must be fundamentally indeterministic so long as they accept certain other metaphysical commitments: either a perfect initial distribution of states in the universe or some form of primitive dispositional properties. Finally, the study sketches out a future research project for modal interpretations based on developing quantified quantum logic.

    Kopeć, Grzegorz; Magoń, Wojciech; Hołda, Mateusz; Podolec, Piotr


    Electrocardiogram (ECG) is commonly used in diagnosis of heart diseases, including many life-threatening disorders. We aimed to assess skills in ECG interpretation among Polish medical students and to analyze the determinants of these skills. Undergraduates from all Polish medical schools were asked to complete a web-based survey containing 18 ECG strips. Questions concerned primary ECG parameters (rate, rhythm, and axis), emergencies, and common ECG abnormalities. Analysis was restricted to students in their clinical years (4th-6th), and students in their preclinical years (1st-3rd) were used as controls. We enrolled 536 medical students (females: n=299; 55.8%), aged 19 to 31 (23±1.6) years from all Polish medical schools. Most (72%) were in their clinical years. The overall rate of good response was better in students in years 4th-5th than those in years 1st-3rd (66% vs. 56%; pmedical students in their clinical years have a good level of competency in interpreting the primary ECG parameters, but their ability to recognize ECG signs of emergencies and common heart abnormalities is low. ECG interpretation skills are determined by self-education but not by attendance at regular ECG classes. Our results indicate qualitative and quantitative deficiencies in teaching ECG interpretation at medical schools.

  15. A review of computer aided interpretation technology for the evaluation of radiographs of aluminum welds (United States)

    Lloyd, J. F., Sr.


    Industrial radiography is a well established, reliable means of providing nondestructive structural integrity information. The majority of industrial radiographs are interpreted by trained human eyes using transmitted light and various visual aids. Hundreds of miles of radiographic information are evaluated, documented and archived annually. In many instances, there are serious considerations in terms of interpreter fatigue, subjectivity and limited archival space. Quite often it is difficult to quickly retrieve radiographic information for further analysis or investigation. Methods of improving the quality and efficiency of the radiographic process are being explored, developed and incorporated whenever feasible. High resolution cameras, digital image processing, and mass digital data storage offer interesting possibilities for improving the industrial radiographic process. A review is presented of computer aided radiographic interpretation technology in terms of how it could be used to enhance the radiographic interpretation process in evaluating radiographs of aluminum welds.

  16. Interobserver reproducibility in pathologist interpretation of columnar-lined esophagus. (United States)

    Mastracci, Luca; Piol, Nataniele; Molinaro, Luca; Pitto, Francesca; Tinelli, Carmine; De Silvestri, Annalisa; Fiocca, Roberto; Grillo, Federica


    Confirmation of endoscopically suspected esophageal metaplasia (ESEM) requires histology, but confusion in the histological definition of columnar-lined esophagus (CLE) is a longstanding problem. The aim of this study is to evaluate interpathologist variability in the interpretation of CLE. Thirty pathologists were invited to review three ten-case sets of CLE biopsies. In the first set, the cases were provided with descriptive endoscopy only; in the second and the third sets, ESEM extent using Prague criteria was provided. Moreover, participants were required to refer to a diagnostic chart for evaluation of the third set. Agreement was statistically assessed using Randolph's free-marginal multirater kappa. While substantial agreement in recognizing columnar epithelium (K = 0.76) was recorded, the overall concordance in clinico-pathological diagnosis was low (K = 0.38). The overall concordance rate improved from the first (K = 0.27) to the second (K = 0.40) and third step (K = 0.46). Agreement was substantial when diagnosing Barrett's esophagus (BE) with intestinal metaplasia or inlet patch (K = 0.65 and K = 0.89), respectively, in the third step, while major problems in interpretation of CLE were observed when only cardia/cardia-oxyntic atrophic-type epithelium was present (K = 0.05-0.29). In conclusion, precise endoscopic description and the use of a diagnostic chart increased consistency in CLE interpretation of esophageal biopsies. Agreement was substantial for some diagnostic categories (BE with intestinal metaplasia and inlet patch) with a well-defined clinical profile. Interpretation of cases with cardia/cardia-oxyntic atrophic-type epithelium, with or without ESEM, was least consistent, which reflects lack of clarity of definition and results in variable management of this entity.

  17. The image-interpretation-workstation of the future: lessons learned (United States)

    Maier, S.; van de Camp, F.; Hafermann, J.; Wagner, B.; Peinsipp-Byma, E.; Beyerer, J.


    In recent years, professionally used workstations got increasingly complex and multi-monitor systems are more and more common. Novel interaction techniques like gesture recognition were developed but used mostly for entertainment and gaming purposes. These human computer interfaces are not yet widely used in professional environments where they could greatly improve the user experience. To approach this problem, we combined existing tools in our imageinterpretation-workstation of the future, a multi-monitor workplace comprised of four screens. Each screen is dedicated to a special task in the image interpreting process: a geo-information system to geo-reference the images and provide a spatial reference for the user, an interactive recognition support tool, an annotation tool and a reporting tool. To further support the complex task of image interpreting, self-developed interaction systems for head-pose estimation and hand tracking were used in addition to more common technologies like touchscreens, face identification and speech recognition. A set of experiments were conducted to evaluate the usability of the different interaction systems. Two typical extensive tasks of image interpreting were devised and approved by military personal. They were then tested with a current setup of an image interpreting workstation using only keyboard and mouse against our image-interpretationworkstation of the future. To get a more detailed look at the usefulness of the interaction techniques in a multi-monitorsetup, the hand tracking, head pose estimation and the face recognition were further evaluated using tests inspired by everyday tasks. The results of the evaluation and the discussion are presented in this paper.

  18. Interpretation of patient-reported outcomes. (United States)

    Cappelleri, Joseph C; Bushmakin, Andrew G


    A patient-reported outcome is any report on the status of a patient's health condition that comes directly from the patient. Clear and meaningful interpretation of patient-reported outcome scores are fundamental to their use as they can be valuable in designing studies, evaluating interventions, educating consumers, and informing health policy makers involved with regulatory, reimbursement, and advisory agencies. Interpretation of patient-reported outcome scores, however, is often not well understood because of insufficient data or lack of experience or clinical understanding to draw from. This article provides an update review on two broad approaches--anchor-based and distributed-based--aimed at enhancing the understanding and meaning of patient-reported outcome scores. Anchor-based approaches include percentages based on thresholds, criterion-group interpretation, content-based interpretation, and clinical important difference. Distributed-based approaches include effect size, probability of relative benefit, and responder analysis and cumulative proportions. A third strategy called mediation analysis, which can elucidate a health condition measured by a patient-reported outcome in the context of an intervention's mechanism of action, is also highlighted and illustrated. Mediation analysis in the context of interpretation of patient-reported outcome scores is a relatively new development. The logic and rationale of the three methods are expressed generally. While the three approaches themselves are not new, some applications of them taken from their examples published in the past few years are original and coalesced in this article to add real-life implications of the different methodologies in one integrated report. © The Author(s) 2013 Reprints and permissions:

Our purpose was to suggest the usefulness of theories of complex adaptive systems (CASs) in guiding research interpretation. Specifically, we addressed two questions: (1) What are the implications for interpreting research observations in HCOs of the fact that we are observing relationships among diverse agents? (2) What are the implications for interpreting research observations in HCOs of the fact that we are observing relationships among agents that learn? We defined diversity and learning and the implications of the non-linear relationships among agents from a CAS perspective. We then identified some common analytical practices that were problematic and may lead to conceptual and methodological errors. Then we described strategies for interpreting the results of research observations. We suggest that the task of interpreting research observations of HCOs could be improved if researchers take into account that the systems they study are CASs with non-linear relationships among diverse, learning agents. Our analysis points out how interpretation of research results might be shaped by the fact that HCOs are CASs. We described how learning is, in fact, the result of interactions among diverse agents and that learning can, by itself, reduce or increase agent diversity. We encouraged researchers to be persistent in their attempts to reason about complex systems and learn to attend not only to structures, but also to processes and functions of complex systems.

    Trained medical interpreters are instrumental to patient satisfaction and quality of care. They are especially important in student-run clinics, where many patients have limited English proficiency. Because student-run clinics have ties to their medical schools, they have access to bilingual students who may volunteer to interpret, but are not necessarily formally trained. To study the feasibility and efficacy of leveraging medical student volunteers to improve interpretation services, we performed a pilot study at the student-run clinic at the Icahn School of Medicine at Mount Sinai. In each fall semester in 2012-2015, we implemented a 6-h course providing didactic and interactive training on medical Spanish interpreting techniques and language skills to bilingual students. We then assessed the impact of the course on interpreter abilities. Participants' comfort levels, understanding of their roles, and understanding of terminology significantly increased after the course (p interpreter training course tailored for medical students in the setting of a student-run clinic is feasible and effective. This program for training qualified student interpreters can serve as a model for other settings where medical students serve as interpreters.

  2. A survey of language barriers from the perspective of pediatric oncologists, interpreters, and parents. (United States)

    Abbe, Marisa; Simon, Christian; Angiolillo, Anne; Ruccione, Kathy; Kodish, Eric D


    Oncologists in the US increasingly face the challenge of communicating with non-English speaking parents of children with cancer. This study explores this challenge from the perspectives of a sample of pediatric oncologists, interpreters, and Spanish-speaking parents of children with newly diagnosed leukemia. Thirty-seven oncologists and 17 professional language interpreters based at two non-profit pediatric hospitals in the US were surveyed on the topic of language barriers in pediatric care. Seventeen parents who communicated with their child's oncologist through an interpreter were also surveyed. All groups expressed considerable concern over the process of communicating across a language barrier. For oncologists, these concerns included the accuracy and completeness of interpretations, complexity of information, and loss of confidence and control over the communication process. For interpreters, they included complexity of information, information overload, and lack of clinician sensitivity toward the cultural and socioeconomic backgrounds of limited English proficiency (LEP) families. Parent concerns included difficulties comprehending information and anxiety over the possibility of missing out on important information. All groups provided multiple suggestions for improving communication across a language barrier. Oncologists, interpreters, and parents expressed considerable concern over the process of communicating across a language barrier. Some of these concerns could be minimized through efforts to boost interpreter accuracy and completeness, including the use of more simple, easy to understand language. Other issues, such as differences in culture and socioeconomic background, warrant consideration of the intercultural knowledge and skills of interpreters. (c) 2006 Wiley-Liss, Inc.

  3. Experiences of interpreters in supporting the transition from oncology to palliative care: A qualitative study. (United States)

    Kirby, Emma; Broom, Alex; Good, Phillip; Bowden, Vanessa; Lwin, Zarnie


    Medical consultations focused on managing the transition to palliative care are interpersonally challenging and require high levels of communicative competence. In the context of non-English speaking patients, communication challenges are further complicated due to the requirement of interpreting; a process with the potential to add intense layers of complexity in the clinical encounter, such as misunderstanding, misrepresentation and power imbalances. The aim of the study was to explore the experiences and perspectives of professional interpreters in supporting the transition of culturally and linguistically diverse patients to specialist palliative care. Qualitative, semistructured interviews with 20 professional interpreters working in oncology and palliative care settings in two metropolitan hospitals in Queensland, Australia. Four key themes emerged from the thematic analysis: the challenges of translating the meaning of "palliative care"; managing interpreting in the presence of family care-givers; communicating and expressing sensitivity while remaining professional and interpreters' own emotional burden of difficult clinic encounters between doctor and patient negotiations. The results suggest that interpreters face a range of often concealed interpersonal and interprofessional challenges and recognition of such dynamics will help provide necessary support for these key stakeholders in the transition to palliative care. Enriched understanding of interpreters' experiences has clinical implications on improving how health professionals interact and work with interpreters in this sensitive setting. © 2016 John Wiley & Sons Australia, Ltd.

(Dept. of Radiology, Capio Diagnostic, Capio St. Goeran Hospital, Stockholm (Sweden)); Winter, R. (Dept. of Clinical Physiology, Karolinska Inst., Karolinska Univ. Hospital, Stockholm (Sweden))


    Background: Cardiac computed tomography (CT) has gained increasing acceptance for diagnosing obstructive coronary artery disease (CAD). Several guidelines have been published on required education for proficiency in the interpretation of these examinations. Purpose: To describe the learning-curve effect of the interpretation of 100 consecutive cardiac CT examinations aimed at diagnosing CAD. The diagnostic accuracy of radiologists and radiographers was also compared. Material and Methods: Two radiologists and two radiographers, all with no prior experience in evaluation of cardiac CT, independently underwent a dedicated training program of 100 examinations randomized into 10 blocks (sessions), with 10 cases in each. They independently evaluated the coronary arteries regarding significant obstructive CAD. After every session, individual feedback on diagnostic accuracy and comparison with the corresponding invasive coronary angiography (currently regarded as the gold standard to detect coronary lesions) was given. The time required for interpretation was recorded. Results: The mean review time decreased (P<0.0001) successively during the 10 sessions for all the observers together. The first session had a mean review time of 32 min, and the last session 16 min. No significant improvement in sensitivity, specificity, or negative predictive value (NPV) was observed. For positive predictive value (PPV), there was an improvement for the radiologists (P<0.05), but not for the radiographers. The radiographers had a higher total specificity compared to the radiologists (P<0.01). Conclusion: The review time for novices in cardiac CT was approximately halved during the first 100 cases, with maintained accuracy. There was a learning-curve effect in PPV for the radiologists. The diagnostic accuracy of dedicated radiographers indicates that they might be considered to be included as part of the evaluation team

  6. Working with interpreters: an interactive Web-based learning module. (United States)

    improved by 20% on the MCQ post-test and 86% of the students were satisfied with the learning experience and acquired new knowledge. As a result of their participation in the module, students examined their own cultural and linguistic backgrounds and made the following comments: "I am interested in exploring the way my own culture and cultural biases could impact my working with patients from other cultures"; "This module has opened my eyes to the fears and concerns of immigrants who do not speak English." Therefore, this pilot of the module effectively imparted guidelines for, and raised awareness of, medical interpreting. The most common critique of the module was that as a result of technical difficulties, it was time-consuming. A more rigorous evaluation is planned for the next academic year. We are also working to enrich and enhance the module for more experienced clinicians (GME and CME). As a complementary educational tool, the Internet has the advantages of allowing students to work at their own paces, view engaging video clips, and participate in interactive learning with immediate feedback and self-assessment.

  7. Treating Metaphor Interpretation Deficits Subsequent to Right Hemisphere Brain Damage: Preliminary Results (United States)

    Lundgren, Kristine; Brownell, Hiram; Cayer-Meade, Carol; Milione, Janet; Kearns, Kevin


    Purpose This investigation sought to determine whether a structured intervention focused on improving use of semantic associations could improve patients’ ability to provide oral interpretations of metaphors following Right Hemisphere Damage (RHD). Methods Principles of single subject experimental design provided the basis for the study. Five patients received either 10 or 20 baseline assessments of oral metaphor interpretation and, as a control, assessments of line orientation skill. They then received approximately 10 one-hour sessions of structured intervention to improve oral metaphor interpretation followed by post-training assessments and a 3 month follow up. Results Patients’ performances revealed evidence of good response to training as shown by patients' ability to reach criterion on all intervention tasks and by their significant improvement on oral metaphor interpretation. There was relatively little improvement on the line orientation task. Discussion The results of this study support the clinical usefulness of this new approach to treating communication deficits associated with RHD due to stroke, even years post-onset. There are, however, questions that remain unanswered. For example, additional data will be needed to gauge how a patient’s severity of impairment relates to the potential for improvement, to chart the durability and scope of improvement associated with the training, and to determine the type of visuospatial ability needed for using this type of pictorial material.

  8. Generating Interpretable Fuzzy Systems for Classification Problems

    Directory of Open Access Journals (Sweden)

    Juan A. Contreras-Montes


    Full Text Available This paper presents a new method to generate interpretable fuzzy systems from training data to deal with classification problems. The antecedent partition uses triangular sets with 0.5 interpolations avoiding the presence of complex overlapping that happens in another method. Singleton consequents are generated form the projection of the modal values of each triangular membership function into the output space. Least square method is used to adjust the consequents. The proposed method gets a higher average classification accuracy rate than the existing methods with a reduced number of rules andparameters and without sacrificing the fuzzy system interpretability. The proposed approach is applied to two classical classification problems: Iris data and the Wisconsin Breast Cancer classification problem.

  9. On Thermodynamic Interpretation of Transfer Entropy

    Directory of Open Access Journals (Sweden)

    Don C. Price


    Full Text Available We propose a thermodynamic interpretation of transfer entropy near equilibrium, using a specialised Boltzmann’s principle. The approach relates conditional probabilities to the probabilities of the corresponding state transitions. This in turn characterises transfer entropy as a difference of two entropy rates: the rate for a resultant transition and another rate for a possibly irreversible transition within the system affected by an additional source. We then show that this difference, the local transfer entropy, is proportional to the external entropy production, possibly due to irreversibility. Near equilibrium, transfer entropy is also interpreted as the difference in equilibrium stabilities with respect to two scenarios: a default case and the case with an additional source. Finally, we demonstrated that such a thermodynamic treatment is not applicable to information flow, a measure of causal effect.

  10. Pharmacy students' interpretation of academic integrity. (United States)

    Emmerton, Lynne; Jiang, Hai; McKauge, Leigh


    To explore pharmacy students' recognition and interpretation of situations constituting breaches of academic integrity. A survey instrument comprising 10 hypothetical student(s) scenarios was completed by 852 students in the bachelor of pharmacy program at an Australian university. The scenarios were relevant to current modes of assessment and presented degrees of ambiguity around academic integrity. Identification of the hypothetical student(s) at fault, particularly in the deliberately ambiguous scenarios, was not related to the respondents' year of study or sex. Students with fewer years of postsecondary education were more definitive in their interpretation of contentious cases. Respondents from all 4 years of study reported witnessing many of these behaviors among their peers. This study provided novel insight into the ambiguity surrounding academic integrity and students' perceptions relating to the deliberate or inadvertent involvement of other parties.

  12. Design, operation, and interpretation of clinical trials. (United States)

    Pihlstrom, B L; Barnett, M L


    Randomized controlled clinical trials offer the best evidence for changing clinical practice and informing public health policy. Using examples from the literature, this paper reviews clinical trials for those who may be unfamiliar with their design, operation, and interpretation. In the design of a clinical trial, the question to be answered and a clinically meaningful outcome must be clearly defined. Ethics must be considered, sample size carefully estimated, and use of biomarkers and surrogate outcomes understood. Prominent issues in trial implementation include developing a manual of operations, trial registration, subject recruitment and retention, use of a data coordinating center, and data and safety monitoring. Interpretation of clinical trials requires understanding differences between efficacy and effectiveness; superiority, equivalence, and non-inferiority; intent-to-treat; primary and secondary analyses; and limitations of unregistered small clinical trials compared with large multi-center Phase III trials that are more likely to be representative of a population and change clinical practice or public health policy.

  13. Andries van Aarde’s Matthew Interpretation

    Directory of Open Access Journals (Sweden)

    Jurie H. le Roux


    Full Text Available This article focused on Andries van Aarde’s interpretation of the Gospel of Matthew. It argues that Van Aarde has changed his approach to Matthew in the course of time. At the beginning of his career he focused on structural analysis and even made a contribution to the Gattung problem from a structural perspective. Then his attention shifted to narrative criticism and social-scientific criticism. Van Aarde’s consistent narratological interpretation of Matthew enabled him to identify Matthew’s ideology and to determine the way in which it took shape on the surface structure. This narratological investigation also shed new light on, amongst others, the parables, the characters and the problem of direct and indirect discourse. To conclude the article, some critical statements with regard to the historical understanding of the Gospel of Matthew were formulated.

  14. Interpreting Quantum Logic as a Pragmatic Structure (United States)

    Garola, Claudio


    Many scholars maintain that the language of quantum mechanics introduces a quantum notion of truth which is formalized by (standard, sharp) quantum logic and is incompatible with the classical (Tarskian) notion of truth. We show that quantum logic can be identified (up to an equivalence relation) with a fragment of a pragmatic language LGP of assertive formulas, that are justified or unjustified rather than trueor false. Quantum logic can then be interpreted as an algebraic structure that formalizes properties of the notion of empirical justification according to quantum mechanics rather than properties of a quantum notion of truth. This conclusion agrees with a general integrationist perspective that interprets nonstandard logics as theories of metalinguistic notions different from truth, thus avoiding incompatibility with classical notions and preserving the globality of logic.

  16. Towards Abstract Interpretation of Epistemic Logic

    DEFF Research Database (Denmark)

    Ajspur, Mai; Gallagher, John Patrick

    The model-checking problem is to decide, given a formula φ and an interpretation M, whether M satisfies φ, written M |= φ. Model-checking algorithms for temporal logics were initially developed with finite models (such as models of hardware) in mind so that M |= φ is decidable. As interest grew...... in model-checking infinite systems, other approaches were developed based on approximating the model-checking algorithm so that it still terminates with some useful output. In this work we present a model-checking algorithm for a multiagent epistemic logic contain- ing operators for common and distributed...... knowledge. The model-checker is developed as a function directly from the semantics of the logic, in a style that could be applied straight- forwardly to derive model-checkers for other logics. Secondly, we consider how to abstract the model-checker using abstract interpretation, yielding a procedure...

  17. Alterations during medical interpretation of ICU family conferences that interfere with or enhance communication. (United States)

    Pham, Kiemanh; Thornton, J Daryl; Engelberg, Ruth A; Jackson, J Carey; Curtis, J Randall


    Many conferences in the ICU occur with the families of patients with limited English proficiency, requiring a medical interpreter. Despite the importance of medical interpretation, little is known about the alterations that occur and their effect on communication. This study characterizes the types, prevalence, and potential effects of alterations in interpretation during ICU family conferences involving end-of-life discussions. We identified ICU family conferences in two hospitals in which a medical interpreter was used. Ten conferences were audiotaped; 9 physicians led these conferences, and 70 family members participated. Research interpreters different from those attending the conference translated the non-English language portions of the audiotaped conferences. We identified interpretation alterations, grouped them into four types, and categorized their potential effects on communication. For each interpreted exchange between clinicians and family, there was a 55% chance that an alteration would occur. These alterations included additions, omissions, substitutions, and editorializations. Over three quarters of alterations were judged to have potentially clinically significant consequences on the goals of the conference. Of the potentially significant alterations, 93% were likely to have a negative effect on communication; the remainder, a positive effect. The alterations with potentially negative effects included interference with the transfer of information, reduced emotional support, and reduced rapport. Those with potential positive effects included improvements in conveying information and emotional support. Alterations in medical interpretation seem to occur frequently and often have the potential for negative consequences on the common goals of the family conference. Further studies examining and addressing these alterations may help clinicians and interpreters to improve communication with family members during ICU family conferences.
