    Thematic Mapping from Satellite Imagery: A Guidebook discusses methods in producing maps using satellite images. The book is comprised of five chapters; each chapter covers one stage of the process. Chapter 1 tackles the satellite remote sensing imaging and its cartographic significance. Chapter 2 discusses the production processes for extracting information from satellite data. The next chapter covers the methods for combining satellite-derived information with that obtained from conventional sources. Chapter 4 deals with design and semiology for cartographic representation, and Chapter 5 pre

    Two problems which exist while attempting to test the accuracy of thematic maps and mapping are: (1) evaluating the accuracy of thematic content, and (2) evaluating the effects of the variables on thematic mapping. Statistical analysis techniques are applicable to both these problems and include techniques for sampling the data and determining their accuracy. In addition, techniques for hypothesis testing, or inferential statistics, are used when comparing the effects of variables. A comprehensive and valid accuracy test of a classification project, such as thematic mapping from remotely sensed data, includes the following components of statistical analysis: (1) sample design, including the sample distribution, sample size, size of the sample unit, and sampling procedure; and (2) accuracy estimation, including estimation of the variance and confidence limits. Careful consideration must be given to the minimum sample size necessary to validate the accuracy of a given. classification category. The results of an accuracy test are presented in a contingency table sometimes called a classification error matrix. Usually the rows represent the interpretation, and the columns represent the verification. The diagonal elements represent the correct classifications. The remaining elements of the rows represent errors by commission, and the remaining elements of the columns represent the errors of omission. For tests of hypothesis that compare variables, the general practice has been to use only the diagonal elements from several related classification error matrices. These data are arranged in the form of another contingency table. The columns of the table represent the different variables being compared, such as different scales of mapping. The rows represent the blocking characteristics, such as the various categories of classification. The values in the cells of the tables might be the counts of correct classification or the binomial proportions of these counts divided by

    The challenges of installing underground terrestrial pipelines in regions with different morphologic characteristics include geotechnical problems such as superficial erosion or landslides. Due to this risk, TransPetro pipeline routes require continuous geologic-geotechnical inspections. This paper presented a methodology to detect possible risk of a geotechnical nature. The methodology uses remote sensing technology combined with geographic information system (GIS) geoprocessing. Aerial photography interpretation provides the visualization of risk features along pipelines and adjacent areas. The features of risk identified during photointerpretation are digitized and georeferenced, thereby facilitating geoprocessing. All data statistics are then analyzed in such a way to identify areas of high risk for geotechnical occurrence. The analyses allowed for the creation of a risk index, which was calculated to portions of 5 km of the pipeline. Risk was ranked in terms of high, medium and low susceptibility to geotechnical accidents. The geotechnical thematic mapping (GTM) was then created to predict geotechnical risk areas. The GTM was also incorporated into the 2002 standard for management of pipeline structural integrity due to its capability of classifying pipeline routes according to susceptibility to geological-geotechnical accidents. Inspection frequency can be established based on this classification. In addition to measuring the effectiveness of applied engineering techniques, the monitoring will also improve the understanding of the evolution of rights-of-way. 18 refs., 3 tabs.

  5. The Conceptual Framework of Thematic Mapping in Case Conceptualization.

    2017-04-01

    This article, the 3rd in a series of 5, introduces the conceptual framework for thematic mapping, a novel approach to case conceptualization. The framework is transtheoretical in that it is not constrained by the tenets or concepts of any one therapeutic orientation and transdiagnostic in that it conceptualizes clients outside the constraints of diagnostic criteria. Thematic mapping comprises 4 components: a definition, foundational principles, defining features, and core concepts. These components of the framework, deemed building blocks, are explained in this article. Like the foundation of any structure, the heuristic value of the method requires that the building blocks have integrity, coherence, and sound anchoring. We assert that the conceptual framework provides a solid foundation, making thematic mapping a potential asset in mental health treatment. © 2017 Wiley Periodicals, Inc.

    The new Solar Ultraviolet Imager (SUVI) instruments aboard NOAA's GOES-R series satellites collect continuous, high-quality imagery of the Sun in six wavelengths. SUVI imagers produce at least one image every 10 seconds, or 8,640 images per day, considerably more data than observers can digest in real time. Over the projected 20-year lifetime of the four GOES-R series spacecraft, SUVI will provide critical imagery for space weather forecasters and produce an extensive but unwieldy archive. In order to condense the database into a dynamic and searchable form we have developed solar thematic maps, maps of the Sun with key features, such as coronal holes, flares, bright regions, quiet corona, and filaments, identified. Thematic maps will be used in NOAA's Space Weather Prediction Center to improve forecaster response time to solar events and generate several derivative products. Likewise, scientists use thematic maps to find observations of interest more easily. Using an expert-trained, naive Bayesian classifier to label each pixel, we create thematic maps in real-time. We created software to collect expert classifications of solar features based on SUVI images. Using this software, we compiled a database of expert classifications, from which we could characterize the distribution of pixels associated with each theme. Given new images, the classifier assigns each pixel the most appropriate label according to the trained distribution. Here we describe the software to collect expert training and the successes and limitations of the classifier. The algorithm excellently identifies coronal holes but fails to consistently detect filaments and prominences. We compare the Bayesian classifier to an artificial neural network, one of our attempts to overcome the aforementioned limitations. These results are very promising and encourage future research into an ensemble classification approach.

  10. Communicating Thematic Data Quality with Web Map Services

    2015-10-01

    Full Text Available Geospatial information of many kinds, from topographic maps to scientific data, is increasingly being made available through web mapping services. These allow georeferenced map images to be served from data stores and displayed in websites and geographic information systems, where they can be integrated with other geographic information. The Open Geospatial Consortium’s Web Map Service (WMS standard has been widely adopted in diverse communities for sharing data in this way. However, current services typically provide little or no information about the quality or accuracy of the data they serve. In this paper we will describe the design and implementation of a new “quality-enabled” profile of WMS, which we call “WMS-Q”. This describes how information about data quality can be transmitted to the user through WMS. Such information can exist at many levels, from entire datasets to individual measurements, and includes the many different ways in which data uncertainty can be expressed. We also describe proposed extensions to the Symbology Encoding specification, which include provision for visualizing uncertainty in raster data in a number of different ways, including contours, shading and bivariate colour maps. We shall also describe new open-source implementations of the new specifications, which include both clients and servers.

  11. Possibility of Preparing Thematic Maps Through Developing of the Geographic Information System (GIS

    Full Text Available It is a well known fact that nowadays planning of sustainable development and land use requires a lot of reliable and good quality information, which serves as the basis for timely and adequate decision-making. One of the most important forms of information is presented in various maps. Until recently, preparing of such data was, no doubt, a rather complex and time-consuming task. However, at present, thanks to, first of all, the GIS technology it is possible to develop corresponding geographic information systems with databases which then allow comparatively simple and quick preparing of necessary thematic maps. The paper first presents the method of developing the Geographic and Land Information System (GLIS of the Karlovac County which, although developed for the purpose of agricultural development, may also be used in the development of forestry, environment protection, physical planning, water management and for soil conservation and regulation. Several examples illustrate the possibilities of preparing of specialised maps based on this GLIS. The basic data for developing of the geographic and land information system were the data of the Basic Soil Maps and topographic maps of the Republic of Croatia at the scale of 1:50 000 or 1:25 000, and the data from other studies made for the purpose of agricultural development in the area. These data, together with the results of processing and analysing of this data, by digitalisation, generalisation and interpolation, were incorporated into an integrated database of the geographic and land information system by using Microstation, AutoCad, ArcInfo, ArcWiew and Access software and the corresponding hardware. GLIS database consists of two parts. The first part includes the data referring to polygons - pedological contours, and the other part the data on pedological profiles. The base is organised in a way that enable the preparation of different thematic maps, but it can be also used in digital form

  12. Effect of thematic map misclassification on landscape multi-metric assessment.

    2015-06-01

    Advancements in remote sensing and computational tools have increased our awareness of large-scale environmental problems, thereby creating a need for monitoring, assessment, and management at these scales. Over the last decade, several watershed and regional multi-metric indices have been developed to assist decision-makers with planning actions of these scales. However, these tools use remote-sensing products that are subject to land-cover misclassification, and these errors are rarely incorporated in the assessment results. Here, we examined the sensitivity of a landscape-scale multi-metric index (MMI) to error from thematic land-cover misclassification and the implications of this uncertainty for resource management decisions. Through a case study, we used a simplified floodplain MMI assessment tool, whose metrics were derived from Landsat thematic maps, to initially provide results that were naive to thematic misclassification error. Using a Monte Carlo simulation model, we then incorporated map misclassification error into our MMI, resulting in four important conclusions: (1) each metric had a different sensitivity to error; (2) within each metric, the bias between the error-naive metric scores and simulated scores that incorporate potential error varied in magnitude and direction depending on the underlying land cover at each assessment site; (3) collectively, when the metrics were combined into a multi-metric index, the effects were attenuated; and (4) the index bias indicated that our naive assessment model may overestimate floodplain condition of sites with limited human impacts and, to a lesser extent, either over- or underestimated floodplain condition of sites with mixed land use.

    Euphorbia esula L. (leafy spurge) is an invasive weed that is a major problem in much of the Upper Great Plains region, including parts of Montana, South Dakota, North Dakota, Nebraska, and Wyoming. Infestations in North Dakota alone have had a serious economic impact, estimated at $87 million annually in 1991, to the state's wildlife, tourism, and agricultural economy. Leafy spurge degrades prairie and badland ecosystems by displacing native grasses and forbs. It is a major threat to protected ecosystems in many national parks, national wild lands, and state recreational areas in the region. This study explores the use of Landsat 7 Enhanced Thematic Mapper Plus (Landsat) imagery and derived products as a management tool for mapping leafy spurge in Theodore Roosevelt National Park, in southwestern North Dakota. An unsupervised clustering approach was used to map leafy spurge classes and resulted in overall classification accuracies of approximately 63%. The uses of Landsat imagery did not provide the accuracy required for detailed mapping of small patches of the weed. However, it demonstrated the potential for mapping broad-scale (regional) leafy spurge occurrence. This paper offers recommendations on the suitability of Landsat imagery as a tool for use by resource managers to map and monitor leafy spurge populations over large areas.

    The author has identified the following significant results. The images can be positioned in an absolute reference system (geographical coordinates or polar stereographic coordinates) by means of their marginal indicators. By digital analysis of LANDSAT data and geometric positioning of pixels in UTM projection, accuracy was achieved for corrected MSS information which could be used for updating maps at scale 1:200,000 or smaller. Results show that adjustment of the UTM grid was better obtained by a first order, or even second order, algorithm of geometric correction. Digital analysis of LANDSAT data from the Madrid area showed that this line of study was promising for automatic classification of data applied to thematic cartography and soils identification.

  15. Mapping contact metamorphic aureoles in Extremadura, Spain, using Landsat thematic mapper images

    In the Extremadura region of western Spain, Ag, Pb, Zn, and Sn deposits occur in the pieces of late Hercynian granitic plutons and near the pluton contacts in late Proterozoic slate and metagraywacke that have been regionally metamorphosed to the green schist facies. The plutons generally are well exposed and have distinctive geomorphological expression and vegetation; poor exposures of the metasedimentary host rocks and extensive cultivation, however, make delineation of the contact aureoles difficult. Landsat Thematic Mapper (TM) images have been used to distinguish soil developed on the contact metamorphic rocks from soil formed on the stratigraphically equivalent slate-metagraywacke sequence. The mineral constituents of these soils are similar, except that muscovite is more common in the contact metamorphic soil; carbonaceous material is common in both soils. Contact metamorphic soil have lower reflectance, especially in the 1.6-micrometers wavelength region (TM 5), and weaker Al-OH, Mg-OH, and Fe3+ absorption features than do spectra of the slate-metagraywacke soil. The low-reflectance and subdued absorption features exhibited by the contact metamorphic soil spectra are attributed to the high absorption coefficient f the carbonaceous material caused by heating during emplacement of the granitic plutons. These spectral differences are evident in a TM 4/3, 4/5, 3/1 color-composite image. Initially, this image was used to outline the contact aureoles, but digital classification of the TM data was necessary for generating internally consistent maps of the distribution of the exposed contact metamorphic soil. In an August 1984, TM scene of the Caceras area, the plowed, vegetation-free fields were identified by their low TM 4/3 values. Then, ranges of TM 4/5 and 3/1 values were determine for selected plower fields within and outside the contact aureoles; TM 5 produced results similar to TM 4/5.

    Playing role as coastal shield with enormous economic value and ecological functions, mangrove forest management is always challenging to be studied. As either the largest archipelagic countryor the largest mangrove forest habitat around the globe, Indonesia needs a national mangrove forest baseline data and its updating for coastal management. Many stakeholders and institutions, including Geospatial Information Agency (BIG), had conducted mangrove mapping and updating. However, in order to achieve one mangrove national data, coordination and synergy among stakeholders and institutions such as: the Ministry of Environment and Forestry as mangrove custodian, Indonesian National Institute of Aeronautics and Space, Ministry of Marine and Fisheries, and BIG aligned with the National Mangrove Working Group is needed. A fundamental step for national mangrove forest management is the establishment of National One Map Mangrove Program by means of coordination, synchronization, and integration of mangrove geospatial data from various stakeholders. This paper will discuss the technical process of data integration and field survey in order to produce One Map Mangrove Sulawesi with the same geo-reference, database, and also standard and specification. The result of One Map Mangrove Sulawesi Program comprises of information about mangrove current status, existing area, and its distribution in Sulawesi.Beside the geospatial data from Ministry of Environment and Forestry and other institutions, the primary data used to map mangrove forest in Sulawesi is SPOT 6 and SPOT 7(year 2014 - 2015) imageries yielded map scale of 1: 25,000. On screen digitation using NIR, Red and Green bands and Normalized Difference Vegetation Index (NDVI)image transformation are applied for the initial canopy density classification. Field survey was doneto obtain field data forvegetation analysis, image classification andre-interpretation. In 2015, the process of producing One Map Mangrove Sulawesi has

    Kershaw County, South Carolina was selected as the study site for analyzing simulated thematic mapper MSS data and dual-polarized X-band synthetic aperture radar (SAR) data. The impact of the improved spatial and spectral characteristics of the LANDSAT D thematic mapper data on computer aided analysis for forest cover type mapping was examined as well as the value of synthetic aperture radar data for differentiating forest and other cover types. The utility of pattern recognition techniques for analyzing SAR data was assessed. Topics covered include: (1) collection and of TMS and reference data; (2) reformatting, geometric and radiometric rectification, and spatial resolution degradation of TMS data; (3) development of training statistics and test data sets; (4) evaluation of different numbers and combinations of wavelength bands on classification performance; (5) comparison among three classification algorithms; and (6) the effectiveness of the principal component transformation in data analysis. The collection, digitization, reformatting, and geometric adjustment of SAR data are also discussed. Image interpretation results and classification results are presented.

    A literature review on radar and spectral band information was conducted and a NC-130 mission was flown carrying the NS001 scanner system which basically corresponds to the channel configuration of the proposed thematic mapper. Aerial photography and other reference data were obtained for the study site, an area approximately 290 sq miles in north central South Carolina. A cover type map was prepared and methods were devised for reformatting and geometrically correcting MSS CRT data. Arrangements were made to obtain LANDSAT data for dates approximating the NC-130 mission. Because of the waveband employed to obtain SEASAT radar data, it was decided to determine if X-band (2.40 cm to 3.75 cm wavelength) imagery is available.

    Full Text Available The primary purpose of the survey for the restoration of Cultural Heritage is the interpretation of the state of building preservation. For this, the advantages of the remote sensing systems that generate dense point cloud (range-based or image-based are not limited only to the acquired data. The paper shows that it is possible to extrapolate very useful information in diagnostics using spatial annotation, with the use of algorithms already implemented in open-source software. Generally, the drawing of degradation maps is the result of manual work, so dependent on the subjectivity of the operator. This paper describes a method of extraction and visualization of information, obtained by mathematical procedures, quantitative, repeatable and verifiable. The case study is a part of the east facade of the Eglise collégiale Saint-Maurice also called Notre Dame des Grâces, in Caromb, in southern France. The work was conducted on the matrix of information contained in the point cloud asci format. The first result is the extrapolation of new geometric descriptors. First, we create the digital maps with the calculated quantities. Subsequently, we have moved to semi-quantitative analyses that transform new data into useful information. We have written the algorithms for accurate selection, for the segmentation of point cloud, for automatic calculation of the real surface and the volume. Furthermore, we have created the graph of spatial distribution of the descriptors. This work shows that if we work during the data processing we can transform the point cloud into an enriched database: the use, the management and the data mining is easy, fast and effective for everyone involved in the restoration process.

    This paper presents a novel technique for dealing with a classic problem that frequently arises in visualization. Very expressive nonlinear transformations can be automatically generated to correct thematic maps so that the areas of map regions are proportional to the thematic variables assigned to them. This helps to eliminate one of the most commonly occurring visual lies that occurs in information visualization. Thematic variables are commonly used in cartography to encode additional information within the spatial layout of a map. Common examples of thematic variables are population density, pollution level and birth rate. The method is illustrated with two examples, mapping interstate speed limits and presidential election results.

    The Typhoon Morakot on August 2009 brought more than 2,000 mm of cumulative rainfall in southern Taiwan, the extreme rainfall event caused serious damage to the Kaoping River basin. The losses were mostly blamed on the landslides along sides of the river, and shifting of the watercourse even led to the failure of roads and bridges, as well as flooding and levees damage happened around the villages on flood bank and terraces. Alluvial fans resulted from debris flow of stream feeders blocked the main watercourse and debris dam was even formed and collapsed. These disasters have highlighted the importance of identification and map the watercourse alteration, surface features of flood plain area and artificial structures soon after the catastrophic typhoon event for natural hazard mitigation. Interpretation of remote sensing images is an efficient approach to acquire spatial information for vast areas, therefore making it suitable for the differentiation of terrain and objects near the vast flood plain areas in a short term. The object-oriented image analysis program (Definiens Developer 7.0) and multi-band high resolution satellite images (QuickBird, DigitalGlobe) was utilized to interpret the flood plain features from Liouguei to Baolai of the the Kaoping River basin after Typhoon Morakot. Object-oriented image interpretation is the process of using homogenized image blocks as elements instead of pixels for different shapes, textures and the mutual relationships of adjacent elements, as well as categorized conditions and rules for semi-artificial interpretation of surface features. Digital terrain models (DTM) are also employed along with the above process to produce layers with specific "landform thematic layers". These layers are especially helpful in differentiating some confusing categories in the spectrum analysis with improved accuracy, such as landslides and riverbeds, as well as terraces, riverbanks, which are of significant engineering importance in disaster

    Supervised and cluster block training statistics were used to analyze the thematic mapper simulation MSS data (both 1979 and 1980 data sets). Cover information classes identified on SAR imagery include: hardwood, pine, mixed pine hardwood, clearcut, pasture, crops, emergent crops, bare soil, urban, and water. Preliminary analysis of the HH and HV polarized SAR data indicate a high variance associated with each information class except for water and bare soil. The large variance for most spectral classes suggests that while the means might be statistically separable, an overlap may exist between the classes which could introduce a significant classification error. The quantitative values of many cover types are much larger on the HV polarization than on the HH, thereby indicating the relative nature of the digitized data values. The mean values of the spectral classes in the areas with larger look angles are greater than the means of the same cover type in other areas having steeper look angles. Difficulty in accurately overlaying the dual polarization of the SAR data was resolved.

    This paper reports how a digitally enhanced Landsat 5 Thematic Mapper mosaic (TM) data, a hand-held color space photograph from one of the early NASA satellite missions (Gemini), and field data were used to delineate three major basement-structural discontinuities (CSDs) with the Zagros Basin of southwestern Iran. Three major subparallel CSDs are, from north to south, Kazerun-Qatar (N05{sup {degrees}W} trend), Razak (N17{degrees}E trend), and Oman (N18{degrees}E). These subparallel CSDs subdivide the Zagros Basin into northern, central, and southern sub-basins. The Razak and Oman CSD enclose a relatively nonproductive area, separating the southern Zagros sub-basin from more productive regions to the northwest and the nonproductive Makran Ranges to the southeast where chromite and iron deposits are common. These findings suggest that CSD may serve as an exploration guide for hydrocarbons and economic mineral deposits, and as a model for developing the tectonic framework of sedimentary basins. The results of this investigation also prove that lineament analysis is a potentially effective method for interpreting the basement-related CSD within a basin setting.

Eligibility criteria were established to include all original research of any design, including trans people or their health information, and published in English in peer-reviewed journals. A complex electronic search strategy based on relevant concepts in 15 databases was developed to obtain a broad range of results linked to transgender, gender diverse, and Two-Spirit individuals and communities. Searches conducted in early 2015 resulted in 25,242 references after removal of duplicates. Based on the number of references, resources, and an objective to capture upwards of 90% of the existing literature, this study is a good candidate for text mining using Latent Dirichlet Allocation to improve efficiency of the screening process. The following information will be collected for evidence mapping: study topic, study design, methods and data sources, recruitment strategies, sample size, sample demographics, researcher name and affiliation, country where research was conducted, funding source, and year of publication. Discussion The proposed research incorporates an extensive search strategy, text mining, and evidence map; it therefore has the potential to build on knowledge in several fields. Review results will increase awareness of existing trans research, identify evidence gaps, and inform

    2013-01-01

    Multispectral satellite data acquired by the ASTER (Advanced Spaceborne Thermal Emission and Reflection Radiometer) and Landsat 7 Enhanced Thematic Mapper Plus (TM) sensors are being used to populate an online Geographic Information System (GIS) of the spatial occurrence of mineral groups and green vegetation across the western conterminous United States and Alaska. These geospatial data are supporting U.S. Geological Survey national-scale mineral deposit database development and other mineral resource and geoenvironmental research as a means of characterizing mineral exposures related to mined and unmined hydrothermally altered rocks and mine waste. This report introduces a new methodology for the automated analysis of Landsat TM data that has been applied to more than 180 scenes covering the western United States. A map of mineral groups and green vegetation produced using this new methodology that covers the western San Juan Mountains, Colorado, and the Four Corners Region is presented. The map is provided as a layered GeoPDF and in GIS-ready digital format. TM data analysis results from other well-studied and mineralogically characterized areas with strong hydrothermal alteration and (or) supergene weathering of near-surface sulfide minerals are also shown and compared with results derived from ASTER data analysis.

    The geological applications of remote sensing technology are discussed, with emphasis given to the analysis of data from the Thematic Mapper (TM) instrument onboard the Landsat 4 satellite. The flight history and design characteristics of the Landsat 4/TM are reviewed, and some difficulties endountered in the interpretation of raw TM data are discussed, including: the volume of data; residual noise; detector-to-detector striping; and spatial misregistration between measurements. Preliminary results of several geological, lithological, geobotanical mapping experiments are presented as examples of the geological applications of the TM, and some areas for improving the guality of TM imagery are identified.

    The article provides an overview of the features of the Magrit web application: a free online thematic mapping tool, presenting a strong pedagogical dimension and making possible to mobilize all the elements necessary for the realization of a thematic map. In this tool, several simple modes of representation are proposed such as proportional maps or choropleth maps. Other, more complex modes are also available such as smoothed maps and cartograms. Each map can be finalized thanks to layout and customization features (projection, scale, orientation, toponyms, etc.) and exported in vector format. Magrit is therefore a complete, light and versatile tool particularly adapted to cartography teaching at the university.

    Full Text Available The U.S. Geological Survey (USGS has begun the development of operational, 30-m resolution annual thematic land cover data to meet the needs of a variety of land cover data users. The Continuous Change Detection and Classification (CCDC algorithm is being evaluated as the likely methodology following early trials. Data for training and testing of CCDC thematic maps have been provided by the USGS Land Cover Trends (LC Trends project, which offers sample-based, manually classified thematic land cover data at 2755 probabilistically located sample blocks across the conterminous United States. These samples represent a high quality, well distributed source of data to train the Random Forest classifier invoked by CCDC. We evaluated the suitability of LC Trends data to train the classifier by assessing the agreement of annual land cover maps output from CCDC with output from the LC Trends project within 14 Landsat path/row locations across the conterminous United States. We used a small subset of circa 2000 data from the LC Trends project to train the classifier, reserving the remaining Trends data from 2000, and incorporating LC Trends data from 1992, to evaluate measures of agreement across time, space, and thematic classes, and to characterize disagreement. Overall agreement ranged from 75% to 98% across the path/rows, and results were largely consistent across time. Land cover types that were well represented in the training data tended to have higher rates of agreement between LC Trends and CCDC outputs. Characteristics of disagreement are being used to improve the use of LC Trends data as a continued source of training information for operational production of annual land cover maps.

    2003-01-01

    Full Text Available Thematic curriculum combines disciplines and media. The process is problem-oriented and the scenario most often follows the logic of exploring or storytelling. Those two approaches to teaching are appropriate because they fit into interdisciplinary and creative open-ended problem solving through play, as insisted upon by thematic curriculum. The matrix, where seven types of abilities intersect with five types of problems according to their degree of openness, defines well the outcomes of teaching. However, it did not prove to be suitable for planning the majority of activities in thematic curriculum, for it follows with difficulty the process of exploring or storytelling i.e. it disrupts the subject matter coherence of thematic curriculum. Therefore, it is suggested that matrix should be used for disciplinary curriculum planning but for that of thematic curriculum only in exclusive cases. The matrix should be used primarily as a framework for evaluating the distribution of various types of abilities and problem situations in teaching. The logic of diverse approaches to teaching reflects itself in the manner of planning and organizing the teaching process. Conceptual, visual-graphic, structural and other aids employed during educational process planning should suit the nature of the approach chosen. On the basis of qualitative investigations of educational process, in the present paper considerations are given to various approaches to teaching development of various drafts for the planning of teaching, and recognition of the logic of storytelling and exploring in thematic curriculum.

    This article aims at developing a graphic proposal for multithematic diagnostic map. The research`s objective is the analysis of the legends of the maps entitled Mapa Diagnostico Geoambiental da Usina Hidreletrica de Igarapava (Geoenvironmental Diagnostic map of the Igarapava Hydroelectric Plant). The analysis emphases on identifying and solving problems resulting in non-respect of the graphic transcription laws which prejudice the map`s clarity. Upon analyzing both versions of the maps, it appeared that these problems were basically resulting from bad legibility and visualization and the inadequate use of retina`s variables in the translation of graphic density and both retinian and angular separation. Graphic density was reduced and retinian separation was improved through leading a better contrast between elements of cartographic base and the Geoenvironment Synthesis Map. The angular separation was increased by using simplified forms to better visualization of the spatial structure of the information. That aspect was laos improved by creating a series of small maps to accompany the legend. Point and line elements were represented on the same map so to not prejudice hierarchical relationship between elements. All these modifications were done without affecting information extraction of the various levels of the Geoenvironmental Synthesis (BASE MAP, VEGETATION and LAND USE, HUMAN ASPECTS, CULTURAL ASPECTS AND ENVIRONMENTAL DYNAMIC). The visualization of the document as a whole was greatly improved with respect to the original proposed format. This research is but one of the various steps to the preparation of an environmental map that aims at giving clear visibility to the thousands of words of an environmental study report.

    One of many potential applications of the thematic mapper (TM) is surface mine monitoring. To assess this potential, data acquired by an aircraft multispectral scanner over Pennsylvania surface mines were preprocessed to simulate the anticipated spectral, spatial, and radiometric characteristics of TM data. False color imagery and thematic maps were derived from the simulated data and compared to imagery and maps derived from LANDSAT multispectral scanner subsystems data. On the basis of this comparison, TM data should definitely increase the detail and accuracy of remotely acquired surface mine information and may enable the remote determination of compliance with reclamation regulations

    The design and testing program for the airborne Landsat-D thematic-mapper simulator (TMS) is summarized. The TMS is intended to provide data similar enough to those expected from Landsat-D to facilitate the development of data-processing software. The design process comprised mainly modifications on the existing MSS-simulator fiber optics, dichroics, and detectors to provide 7-channel coverage of the 0.45-12.3-micron range at 60-deg angle of view, corresponding to a 418-element, 13.8-km-wide ground swath. The TMS is carried on a Lear 23 aircraft operating at 750 km/h and 12-m altitude and equipped with a 15.2-cm aerial mapping camera and a ground-updated inertial navigational system. Agricultural, forestry, and geological trial applications are reviewed, and some sample results are given. The significant improvements predicted for the Landsat-D thematic mapper (relative to the Landsat MSS) are seen as confirmed, with the possible exception of the 120-m-resolution version of channel 7.

    2016-05-01

    Full Text Available Accurate maps of surface water are essential for many environmental applications. Surface water maps can be generated by combining measurements from multiple sources. Precise estimation of surface water using satellite imagery remains a challenging task due to the sensor limitations, complex land cover, topography, and atmospheric conditions. As a complementary dataset, in the case of hilly landscapes, a drainage network can be extracted from high-resolution digital elevation models. Additionally, Volunteered Geographic Information (VGI initiatives, such as OpenStreetMap, can also be used to produce high-resolution surface water masks. In this study, we derive a high-resolution water mask using Landsat 8 imagery and OpenStreetMap as well as (potential a drainage network using 30 m SRTM. Our approach to derive a surface water mask from Landsat 8 imagery comprises the use of a lower 15% percentile of Landsat 8 Top of Atmosphere (TOA reflectance from 2013 to 2015. We introduce a new non-parametric unsupervised method based on the Canny edge filter and Otsu thresholding to detect water in flat areas. For hilly areas, the method is extended with an additional supervised classification step used to refine the water mask. We applied the method across the Murray-Darling basin, Australia. Differences between our new Landsat-based water mask and the OpenStreetMap water mask regarding positional differences along the rivers and overall coverage were analyzed. Our results show that about 50% of the OpenStreetMap linear water features can be confirmed using the water mask extracted from Landsat 8 imagery and the drainage network derived from SRTM. We also show that the observed distances between river features derived from OpenStreetMap and Landsat 8 are mostly smaller than 60 m. The differences between the new water mask and SRTM-based linear features and hilly areas are slightly larger (110 m. The overall agreement between OpenStreetMap and Landsat 8 water

    Cesium (http://cesiumjs.org) is an open source, WebGL-based JavaScript library for virtual globes and 3D maps. It is an excellent tool for 3D thematic visualisations, but to use its full functionality it has to be feed with its own file format, CZML. Unfortunately, this format is not yet supported by any major GIS software. This paper intro- duces a plugin for QGIS, developed by the author, which facilitates the creation of CZML file for various types of visualisations. The usability of Cesium is also examined in various hardware/software environments.

  15. Spatial and thematic assessment of object-based forest stand delineation using an OFA-matrix

    Science.gov (United States)

    Hernando, A.; Tiede, D.; Albrecht, F.; Lang, S.

    2012-10-01

    The delineation and classification of forest stands is a crucial aspect of forest management. Object-based image analysis (OBIA) can be used to produce detailed maps of forest stands from either orthophotos or very high resolution satellite imagery. However, measures are then required for evaluating and quantifying both the spatial and thematic accuracy of the OBIA output. In this paper we present an approach for delineating forest stands and a new Object Fate Analysis (OFA) matrix for accuracy assessment. A two-level object-based orthophoto analysis was first carried out to delineate stands on the Dehesa Boyal public land in central Spain (Avila Province). Two structural features were first created for use in class modelling, enabling good differentiation between stands: a relational tree cover cluster feature, and an arithmetic ratio shadow/tree feature. We then extended the OFA comparison approach with an OFA-matrix to enable concurrent validation of thematic and spatial accuracies. Its diagonal shows the proportion of spatial and thematic coincidence between a reference data and the corresponding classification. New parameters for Spatial Thematic Loyalty (STL), Spatial Thematic Loyalty Overall (STLOVERALL) and Maximal Interfering Object (MIO) are introduced to summarise the OFA-matrix accuracy assessment. A stands map generated by OBIA (classification data) was compared with a map of the same area produced from photo interpretation and field data (reference data). In our example the OFA-matrix results indicate good spatial and thematic accuracies (>65%) for all stand classes except for the shrub stands (31.8%), and a good STLOVERALL (69.8%). The OFA-matrix has therefore been shown to be a valid tool for OBIA accuracy assessment.

    1976-01-01

    Spectral data representative of thematic mapper candidate bands 1 and 3 to 7 were obtained by selecting appropriate combinations of bands from the JSC 24 channel multispectral scanner. Of all the bands assigned, only candidate bands 4 (.74 mu to .80 mu) and 5 (.80 mu to .91 mu) showed consistently high intercorrelation from region to region and time to time. This extremely high correlation persisted when looking at the composite data set in a multitemporal, multilocation domain. The GISS investigations lend positive confirmation to the hypothesis, that TM bands 4 and 5 are redundant.

    Background Although health care organizations such as hospitals and clinics have widely embraced social media as a means to educate the community on health topics and increase patient loyalty and satisfaction, little is known about the content these organizations actually share when using social media channels. Objective This study aimed to explore the types of content US hospitals post on their Facebook pages and how hospitals’ Facebook activities differ with regard to content types. Methods We collected and thematically analyzed more than 1700 Facebook posts made over a 3-month period by 17 US hospitals. During the first phase, the 2 researchers coded a set of 159 posts and created an initial thematic web of content. During the second phase, the researchers coded the remaining posts and then revised, refined, and validated the initial web of content accordingly. Coding consensus was achieved on 1184 of the 1548 analyzable sampled posts (76.49%). Results We identified a list of 13 unique health social media post themes and classified those themes into 3 thematic groups that included announcing, sharing, and recognizing activities. The most frequently used theme was sharing health information, which appeared in 35.81% (424/1184) of the posts analyzed. Such posts sought to provide health tips and advice to community members. Recognizing special days and recognizing employees were the second and third most frequently used themes, respectively, with 14.95% (177/1184) and 11.82% (140/1184) of the posts containing those themes. The frequency of these themes was surprising as the content was geared more toward stakeholders internal to the organization, although most previous literature has focused on social media as a tool to connect with external stakeholders. In addition, we found many of the posts involved more than one theme, and selected sets of themes co-occurred frequently. For example, 25.4% (45/177) of the posts recognizing special days also included content

    The Plant Life Assessment Network (PLAN) is a Brite Euram Type II Thematic Network, initiated by the European Commission to facilitate structured co-operation between all cost shared action projects already funded by the Commission which fall under this common technical theme. The projects involved address a multiplicity of problems associated with plant life assessment and are drawn from Brite-Euram, Standards, Measurement and Testing, Nuclear Fission Safety and Esprit EC programmes. The main aim of the Network is to initiate, maintain and monitor a fruitful co-operation process between completed, ongoing and future EC R and D projects, thereby promoting improved cross fertilization and enhanced industrial exploitation of R and D results. As the project is in its infancy, this presentation covers the background to the initiative in some detail. In particular two key aspects are highlighted, namely, the requirement of the EC to launch such a network in the area of plant life assessment including its evolution from two small Thematic Research Actions and, secondly, the mechanism for structuring the Network in an ordered and proven way along the lines of the EC/JRC European Networks, PISC, NESC, AMES, ENIQ, ENAIS and EPERC. The operating and financial structure of the Network is detailed with reference made to the role of the executive Steering Committee, The Network Project Leader and the Network Financial Co-ordinator. Each of the 58 projects involved in the Network, representing a wide range of industrial sectors and disciplines, is distributed in terms of their efforts between 4 disciplinary Clusters covering Inspection, Instrumentation and Monitoring, Structural Mechanics and Maintenance. For each of these Clusters, an expert has been appointed as a Project Technical Auditor to support the elected Cluster Co-ordinator to define Cluster Tasks, which contribute to the overall objectives of the project.

    2014-01-01

    Full Text Available The article titled Thematic Tourism vs. Mass Tourism in the Czech Republic is concerned with the relationship between thematic tourism, mass tourism and presuppositions of the tourism development. The authors aim is to compare the turnout of thematic tourism attractions and sights focused on mass tourism paying attention to presuppositions of the tourism development and barriers for the turnout of thematic monuments. Comparisons will be based on presuppositions of tourism development and will be based especially on the specifics of thematic tourism - as a marginal field within the tourism industry. The application part will focus on the comparison of sights with massive turnout in the Czech Republic and thematic landmarks as the subject of thematic tourism. Special attention will be paid to the comparison of the two most visited monuments in the Czech Republic as for mass tourism - the Charles Bridge, and the most visited monument as for thematic tourism - the hydro-power plant Dlouhé Stráně, a technical representative of thematic tourism. Both monuments were elected by general public on the list of Seven Wonders of the Czech Republic in 2013. The aim is to confirm / refute the hypothesis that quality preconditions of tourism development are essential for the development of tourism and visiting tourist attractions. The article will use secondary data analysis methods and author's own field research.

    Estebsari, Fatemeh; Taghdisi, Mohammad Hossein; Mostafaei, Davood; Rahimi, Zahra

    2017-01-01

    Background: Death is a natural and frightening phenomenon, which is inevitable. Previous studies on death, which presented a negative and tedious image of this process, are now being revised and directed towards acceptable death and good death. One of the proposed terms about death and dying is "healthy death", which encourages dealing with death positively and leading a lively and happy life until the last moment. This study aimed to explain the views of Iranians about the elements of healthy death. Methods: This qualitative study was conducted for 12 months in two general hospitals in Tehran (capital of Iran), using the thematic analysis method. After conducting 23 in-depth interviews with 21 participants, transcription of content, and data immersion and analysis, themes, as the smallest meaningful units were extracted, encoded and classified. Results: One main category of healthy death with 10 subthemes, including dying at the right time, dying without hassle, dying without cost, dying without dependency and control, peaceful death, not having difficulty at dying, not dying alone and dying at home, inspired death, preplanned death, and presence of a clergyman or a priest, were extracted as the elements of healthy death from the perspective of the participants in this study. Conclusion: The study findings well explained the elements of healthy death. Paying attention to the conditions and factors causing healthy death by professionals and providing and facilitating quality services for patients in the end stage of life make it possible for patients to experience a healthy death.

    Full Text Available Childhood obesity is a major concern in today's society. Research suggests the inclusion of the views and understandings of a target group facilitates strategies that have better efficacy. The objective of this study was to explore the concepts and themes that make up children's understandings of the causes and consequences of obesity. Participants were selected from Reception (4–5 years old and Year 6 (10–11 years old, and attended a school in an area of Sunderland, in North East England. Participants were separated according to age and gender, resulting in four focus groups, run across two sessions. A thematic analysis (Braun & Clarke, 2006 identified overarching themes evident across all groups, suggesting the key concepts that contribute to children's understandings of obesity are “Knowledge through Education,” “Role Models,” “Fat is Bad,” and “Mixed Messages.” The implications of these findings and considerations of the methodology are discussed in full.

    2010-12-01

    The Earth System Science Education Alliance (ESSEA), an NSF, NASA, and NOAA supported program providing K-12 teacher professional development uses a thematic approach to frame participant inquiry. To address topics such as carbon sequestration, ocean acidification or aerosols, ESSEA online courses present participants with scenarios or contexts depicting an anomaly or perturbation to the Earth system. The courses deepen teachers’ content knowledge within an inquiry environment through reflection, analysis and self-discovery. Courses familiarize participants with Earth system analyses and provide a suite of techniques that can be employed to facilitate student learning, for example, through the use of Problem-based learning (PBL). Problem-based learning (PBL) is designed to "simultaneously develop both problem solving strategies and disciplinary knowledge bases and skills by placing students in the active role of problem-solvers confronted with an ill-structured problem that mirrors real-world problems.” PBL models are generally characterized by the following steps: 1) the presentation of a problem to a small group of students, 2) discussion of the problem among the students which produces tentative explanations of the problem, and 3) an attempt to solve the problem. When participants work to solve ill-structured problems, they are working toward learning generalized procedures for problem solving that will transfer to new situations (University of Delaware, 1999). At the end of an ESSEA course experience, teachers are better equipped with the content and the confidence in using inquiry in the teaching of climate science.

    1984-01-01

    LANDSAT-4 thematic mapper (TM) and multispectral scanner (MSS) data were analyzed to obtain information on data quality and information content. Geometric evaluations were performed to test band-to-band registration accuracy. Thematic mapper overall system resolution was evaluated using scene objects which demonstrated sharp high contrast edge responses. Radiometric evaluation included detector relative calibration, effects of resampling, and coherent noise effects. Information content evaluation was carried out using clustering, principal components, transformed divergence separability measure, and supervised classifiers on test data. A detailed spectral class analysis (multispectral classification) was carried out to compare the information content of the MSS and TM for a large number of scene classes. A temperature-mapping experiment was carried out for a cooling pond to test the quality of thermal-band calibration. Overall TM data quality is very good. The MSS data are noisier than previous LANDSAT results.

    Crowe, Marie; Inder, Maree; Porter, Richard

    2015-07-01

    The objective of this paper is to describe two methods of qualitative analysis - thematic analysis and content analysis - and to examine their use in a mental health context. A description of the processes of thematic analysis and content analysis is provided. These processes are then illustrated by conducting two analyses of the same qualitative data. Transcripts of qualitative interviews are analysed using each method to illustrate these processes. The illustration of the processes highlights the different outcomes from the same set of data. Thematic and content analyses are qualitative methods that serve different research purposes. Thematic analysis provides an interpretation of participants' meanings, while content analysis is a direct representation of participants' responses. These methods provide two ways of understanding meanings and experiences and provide important knowledge in a mental health context. © The Royal Australian and New Zealand College of Psychiatrists 2015.

    Zareiyan, Armin

    2017-01-01

    Identifying what adolescents perceive as their lifestyle and exploring the factors persuading their decisions to engage in or avoid healthy or unhealthy lifestyle behaviors could improve the ability of healthcare professionals to develop innovative preventive strategies and modify negative health behaviors in adolescents. Hence, the literature on adolescent health-related issues reported by adults showed a rarity of information from adolescents themselves. A qualitative study using the thematic analysis approach was conducted. Data were collected by semi-structured, digitally recorded interviews from 32 male adolescents. Interviews were transcribed verbatim, and after collecting the data, the thematic analysis process was started and conducted in six phases. After data collection, the interview texts were transcribed, and approximately 800 initial codes were extracted. The initial codes were reevaluated to yield 48 main themes. Hence, the final thematic map was created as having 5 overarching themes and 12 subthemes, showing that interviewees emphasized unhealthy lifestyle. The components of unhealthy lifestyle seem important to them because they consider that they could lead a healthy lifestyle through elimination of negative behaviors.

  19. Investigating Thematic Roles through Implicit Learning: Evidence from Light Verb Constructions

    Directory of Open Access Journals (Sweden)

    Eva Wittenberg

    2017-06-01

    Full Text Available The syntactic structure of a sentence is usually a strong predictor of its meaning: Each argument noun phrase (i.e., Subject and Object should map onto exactly one thematic role (i.e., Agent and Patient, respectively. Some constructions, however, are exceptions to this pattern. This paper investigates how the syntactic structure of an utterance contributes to its construal, using ditransitive English light verb constructions, such as “Nils gave a hug to his brother,” as an example of such mismatches: Hugging is a two-role event, but the ditransitive syntactic structure suggests a three-role event. Data from an eye-tracking experiment and behavioral categorization data reveal that listeners learn to categorize sentences according to the number of thematic roles they convey, independent of their syntax. Light verb constructions, however, seem to form a category of their own, in which the syntactic structure leads listeners down an initial incorrect assignment of thematic roles, from which they only partly recover. These results suggest an automatic influence of syntactic argument structure on semantic interpretation and event construal, even in highly frequent constructions.

    Tuckett, Anthony G

    2005-01-01

    This article describes an experience of thematic analysis. In order to answer the question 'What does analysis look like in practice?' it describes in brief how the methodology of grounded theory, the epistemology of social constructionism, and the theoretical stance of symbolic interactionism inform analysis. Additionally, analysis is examined by evidencing the systematic processes--here termed organising, coding, writing, theorising, and reading--that led the researcher to develop a final thematic schema.

  1. Hermeneutic phenomenological analysis: the 'possibility' beyond 'actuality' in thematic analysis.

    Science.gov (United States)

    Ho, Ken H M; Chiang, Vico C L; Leung, Doris

    2017-07-01

    This article discusses the ways researchers may become open to manifold interpretations of lived experience through thematic analysis that follows the tradition of hermeneutic phenomenology. Martin Heidegger's thinking about historical contexts of understandings and the notions of 'alētheia' and 'techne' disclose what he called meaning of lived experience, as the 'unchanging Being of changing beings'. While these notions remain central to hermeneutic phenomenological research, novice phenomenologists usually face the problem of how to incorporate these philosophical tenets into thematic analysis. Discussion paper. This discussion paper is based on our experiences of hermeneutic analysis supported by the writings of Heidegger. Literature reviewed for this paper ranges from 1927 - 2014. We draw on data from a study of foreign domestic helpers in Hong Kong to demonstrate how 'dwelling' in the language of participants' 'ek-sistence' supported us in a process of thematic analysis. Data were collected from December 2013 - February 2016. Nurses doing hermeneutic phenomenology have to develop self-awareness of one's own 'taken-for-granted' thinking to disclose the unspoken meanings hidden in the language of participants. Understanding the philosophical tenets of hermeneutic phenomenology allows nurses to preserve possibilities of interpretations in thinking. In so doing, methods of thematic analysis can uncover and present the structure of the meaning of lived experience. We provide our readers with vicarious experience of how to begin cultivating thinking that is aligned with hermeneutic phenomenological philosophical tenets to conduct thematic analysis. © 2017 John Wiley & Sons Ltd.

  2. Methods for converting continuous shrubland ecosystem component values to thematic National Land Cover Database classes

    2017-10-26

    The National Land Cover Database (NLCD) provides thematic land cover and land cover change data at 30-meter spatial resolution for the United States. Although the NLCD is considered to be the leading thematic land cover/land use product and overall classification accuracy across the NLCD is high, performance and consistency in the vast shrub and grasslands of the Western United States is lower than desired. To address these issues and fulfill the needs of stakeholders requiring more accurate rangeland data, the USGS has developed a method to quantify these areas in terms of the continuous cover of several cover components. These components include the cover of shrub, sagebrush (Artemisia spp), big sagebrush (Artemisia tridentata spp.), herbaceous, annual herbaceous, litter, and bare ground, and shrub and sagebrush height. To produce maps of component cover, we collected field data that were then associated with spectral values in WorldView-2 and Landsat imagery using regression tree models. The current report outlines the procedures and results of converting these continuous cover components to three thematic NLCD classes: barren, shrubland, and grassland. To accomplish this, we developed a series of indices and conditional models using continuous cover of shrub, bare ground, herbaceous, and litter as inputs. The continuous cover data are currently available for two large regions in the Western United States. Accuracy of the “cross-walked” product was assessed relative to that of NLCD 2011 at independent validation points (n=787) across these two regions. Overall thematic accuracy of the “cross-walked” product was 0.70, compared to 0.63 for NLCD 2011. The kappa value was considerably higher for the “cross-walked” product at 0.41 compared to 0.28 for NLCD 2011. Accuracy was also evaluated relative to the values of training points (n=75,000) used in the development of the continuous cover components. Again, the “cross-walked” product outperformed NLCD

    Full Text Available ORFEO, the PLEIADES Accompaniment Program, was set up by CNES, the French Space Agency, to prepare, accompany and promote the use and the exploitation of the images acquired by this Very High Resolution optical sensor. It was initiated in 2004 and will last until the end of the first year of the satellite life (launched in December 2011 . The Thematic part of the ORFEO accompaniment program covers a large range of applications, and aims at specifying and validating products and services required by users. An in-depth work of user needs assessments in eight thematic domains (sea and coastline, risks and humanitarian aid, cartography and urban planning, geophysical hazards, hydrology, forestry, agriculture and defence has given rise to a large number of feasibility studies from 2006 to 2011. The Methodological Part of the ORFEO accompaniment program aims at preparing the use and exploitation of these submetric images.

    2015-01-01

    The present study aims at elucidating the impact of stroke on psychosocial functioning of stroke survivors. Data were investigated using interpretative thematic analysis of illness stories produced by 29 patients. Eight themes emerged from the data: Medical Information; Interpersonal Changes; Cognitive, Physical and Emotional Functioning; Strategies of Coping; Social Support; and Information Irrelevant to the Question. The most frequent organization of the themes followed the course of medical intervention and rehabilitation. Narrations of individual patients varied in terms of the presence of particular themes, the amount of information on each topic and organization. The results suggest that the analysis of non-guided illness narratives can be effectively used to identify the thematic areas important to individual stroke patients. The thematic content analysis of stroke stories can allow health professionals to better understand the patient's state of knowledge related to illness as well as his or her socio-psychological functioning which may be useful in the course of planning further assessment and rehabilitation of patients with stroke. Implications for Rehabilitation Experience of illness and life changes following stroke should be recognized as central to the provision of targeted rehabilitation. To understand the subjective perspective a content analysis of the content narrative is recommended. Our study highlights seven general thematic categories that may be regarded as key. The categories may be useful for clinicians to help individuals to clarify their main concerns following a stroke.

    1984-01-01

    Thematic mapper simulator (TMS) data acquired June 7, June 23, and July 31, 1982, and Landsat thematic mapper (TM) data acquired August 2, September 3, and October 21, 1982, over Webster County, Iowa, were examined for within-field soil effects on corn and soybean spectral signatures. It was found that patterns displayed on various computer-generated map products were in close agreement with the detailed soil survey of the area. The difference in spectral values appears to be due to a combination of subtle soil properties and crop growth patterns resulting from the different soil properties. Bands 4 (0.76-.90 micron), 5 (1.55-1.75 micron), and 7 (2.08-2.35 micron) were found to be responding to the within-field soil variability even with increasing ground cover. While these results are preliminary, they do indicate that the soil influence on the vegetation is being detected by TM and should provide improved information relating to crop and soil properties.

    Infertility is a disease that results in the abnormal functioning of the male or female reproductive system. Systematic research planning on any subject, including infertility is in need of solid data regarding previous efforts in this field and to identify the gaps in the research. The aim of this research is to study the thematic structure of articles related to infertility. In this descriptive-analytical study with a scientometric approach, the PubMed database was searched for research publications indexed under "Infertility" over the period 2011-2015. Specific parameters were retrieved from the PubMed. Articles about infertility were analyzed regarding the journal of publication, topics, and countries using Net draw, Ucinet and RavarPreMap software. Also, the most influential topics were analyzed by indicators in the analysis of the network: closeness centrality, and between centrality. The growth in scientific productions the area of infertility over the mentioned period shows an upward trend with the highest growths seen in countries like the United States, the UK, Netherlands, China, and Germany. Moreover, the contents such as fertilization in vitro, adverse effects, spermatozoa, pregnancy rate, and treatment outcome were among the most frequently-used topics in the sphere. Thematic analysis can provide us the research topics, important expressions, and the relationships between them. Users and policymakers can also have a better understanding of the research status in the sphere and consequently, they can plan to increase the quantity and quality of scientific productions in a more efficient way.

    Gout care remains highly suboptimal, contributing to an increased global disease burden. To understand barriers to gout care, our aim was to provide a systematic review and thematic synthesis of qualitative studies worldwide reporting provider and patient perspectives and experiences with management. We conducted a mapped search of MEDLINE, EMBASE, Cumulative Index to Nursing and Allied Health Literature, and Social Sciences Citation Index databases and selected qualitative studies of provider and patient perspectives on gout management. We used thematic synthesis to combine the included studies and identify key themes across studies. We included 20 studies that reported the experiences and perspectives of 480 gout patients and 120 providers spanning five different countries across three continents. We identified three predominant provider themes: knowledge gaps and management approaches; perceptions and beliefs about gout patients; and system barriers to optimal gout care (e.g. time constraints and a lack of incentives). We also identified four predominant themes among gout patients: limited gout knowledge; interactions with health-care providers; attitudes towards and experiences with taking medication; and practical barriers to long-term medication use. Our systematic review of worldwide literature consistently identified gaps in gout knowledge among providers, which is likely to contribute to patients' lack of appropriate education about the fundamental causes of and essential treatment approaches for gout. Furthermore, system barriers among providers and day-to-day challenges of taking long-term medications among patients are considerable. These factors provide key targets to improve the widespread suboptimal gout care.

    Spatz, David M.; Taranik, James V.

    1989-01-01

    The Landsat Thematic Mapper (TM) imagery of the Basin and Range province of southern Nevada was analyzed to identify and map volcanic rock assemblages at three Tertiary calderas. It was found that the longer-wavelength visible and the NIR TM Bands 3, 5, and 7 provide more effective lithologic discrimination than the shorter-wavelength bands, due partly to deeper penetration of the longer-wavelength bands, resulting in more lithologically driven radiances. Shorter-wavelength TM Bands 1 and 2 are affected more by surficial weathering products including desert varnish which may or may not provide an indirect link to lithologic identity. Guidelines for lithologic analysis of volcanic terrains using Landsat TM imagery are outlined.

    2008-09-01

    Full Text Available Discussing the requirements for map data quality, map users and their library/archives environment, the paper focuses on the metadata the user would need for a correct and efficient interpretation of the map data. For such a correct interpretation, knowledge of the rules and guidelines according to which the topographers/cartographers work (such as the kind of data categories to be collected, and the degree to which these rules and guidelines were indeed followed are essential. This is not only valid for the old maps stored in our libraries and archives, but perhaps even more so for the new digital files as the format in which we now have to access our geospatial data. As this would be too much to ask from map librarians/curators, some sort of web 2.0 environment is sought where comments about data quality, completeness and up-to-dateness from knowledgeable map users regarding the specific maps or map series studied can be collected and tagged to scanned versions of these maps on the web. In order not to be subject to the same disadvantages as Wikipedia, where the ‘communis opinio’ rather than scholarship, seems to be decisive, some checking by map curators of this tagged map use information would still be needed. Cooperation between map curators and the International Cartographic Association ( ICA map and spatial data use commission to this end is suggested.

  5. Thematic approach and complex scientific school knowledge: thematic and conceptual organization as proposals of open educational path

    Directory of Open Access Journals (Sweden)

    Giselle Watanabe

    2017-12-01

    Full Text Available In a traditional way, the school knowledge of the sciences, especially in high school, is consolidated from a set of conceptual contents that reflects a given historical construction of the referred science, whether Biology, Physics or Chemistry. In this format, textbooks generally present a more deterministic and reductionist view. There are several consequences, in this scheme that impact the formation of students, among them a mechanized learning and little contextual meaning. In an opposing movement to these limitations, the thematic approaches have been proposed and discussed in research of science teaching field, which propose a treatment of a given topic that is considered relevant for the formation of the youth. However, the organization by themes makes it difficult to integrate into the school curricular culture. Facing this question, this article intends to investigate potential ways of dealing with the two mentioned approaches (traditional and thematic methods, identifying possibilities for the building of knowledge with the potential to promote a more critical and reflexive formation. Methodologically, in this perspective, the research proposes a theoretical reflection from the complexity view about the works with themes, but considering the national school reality. From these considerations emerge the proposal of articulation between two forms of organization, conceptual and thematic, which create space for diversified choices by teachers, based on issues of their school daily life and their training goals. These choices are represented by what we call open thematic pathways. From the results, it may be concluded that the proposed strategies can promote an alternative view of science, the complexity idea, to address questions of an open and dynamic nature and, in this way; it may allow reflections about perceptions, attitudes and values. At same time, it aims to ways of acting of teachers with greater autonomy and protagonism

    Two Landsat Thematic Mapper (TM) images, from July 1984 and July 1992, were used to identify land use/cover changes in the urban and suburban fringe of the city of Huntsville, Alabama. Image difference was the technique used to quantify the change between the two dates. The eight-year period showed a 16% change, mainly from agricultural lands to urban areas generated by the settlement of industrial, commercial, and residential areas. Visual analysis of the change map (i.e., difference image) supported this phenomenon by showing that most changes were occurring in the vicinity of the major roads and highways across the city.

    Full Text Available We report the investigation of the organisation of proper names in two aphasic patients (NBC and FBI. The performance of both patients on spoken word to written word matching tasks was inconsistent, affected by presentation rate and semantic relatedness of the competing responses, all hallmarks of a refractory semantic access dysphasia. In a series of experiments we explored the semantic relatedness effects within their proper name vocabulary, including brand names and person names. First we demonstrated the interaction between very fine grain organisation and personal experience, with one patient with a special interest in the cinema demonstrating higher error rates when identifying the names of actors working in a similar film genre (e.g. action movies: Arnold Schwarzenegger, Bruce Willis, Sylvester Stallone, Mel Gibson than those working in different genres (e.g. Arnold Schwarzenegger, Gregory Peck, Robin Williams, Gene Kelly. Second we compared directly two potential principles of semantic organisation – taxonomic and thematic. Furthermore we considered these principles of organisation in the context of the individuals' personal knowledge base. We selected topics matching the interests and experience of each patient, namely cinema and literature (NBC and naval history (FBI. The stimulus items were arranged in taxonomic arrays (e.g. Jane Austen, Emily Bronte, Agatha Christie, thematic arrays (e.g. Jane Austen, Pride and Prejudice, Mr Darcy, and unrelated arrays (e.g. Jane Austen, Wuthering Heights, Hercule Poirot. We documented that different patterns of taxonomic and thematic organisation were constrained by whether the individual has limited knowledge, moderate knowledge or detailed knowledge of a particular vocabulary. It is suggested that moderate proper name knowledge is primarily organised by taxonomy whereas extensive experience results in a more detailed knowledge base in which theme is a powerful organising principle.

    Teece, Angela; Baker, John

    2017-08-01

    This review aims to use thematic analysis to explore and synthesise evidence of the actual or potential reported effects of diaries on the psychological rehabilitation and recovery of discharged critical care patients. Evidence suggests that whilst admission to critical care may save patient lives, the psychological aftermath can damage a patient's recovery and these needs must be met. Patient diaries are one potential intervention to aid patients understand their critical illness and fill memory gaps caused by sedation, thus reducing psychological distress post-discharge. Prospective patient diaries are increasing in popularity amongst critical care units in the United Kingdom, however there is little evidence base to support their use or understand their effects. A literature review using systematic methods was undertaken of studies relating to the effects of diaries on discharged patients. Thematic analysis enabled the generation and synthesis of themes. Three themes arose from the generated codes: 1) Reclaiming ownership of lost time. 2) Emphasising personhood. 3) Fear and frustration. The diary intervention was shown to have a largely positive impact on survivors' psychological rehabilitation. However, caution should be exercised as recipients could find the contents painful and emotional. Diaries should be embedded within a robust critical care follow-up plan. This review suggests that diaries have the potential to form one aspect of rehabilitation and make a positive impact on patients' recovery. More research is indicated to fully evaluate the effects of diaries on their recipients. Crown Copyright © 2017. Published by Elsevier Ltd. All rights reserved.

    2014-05-01

    Over the last years, several notable initiatives have been developed to provide Solid Earth sciences with an efficient research e-infrastructure. The EPOS project (European Plate Observing System) was included in the EFSRI roadmap in 2008. The 7th European frame program funded an e-science environment such as the Virtual Earthquake and Seismology Research Community in Europe (VERCE). GEO supports the development of the Geohazard SuperSites and Natural Laboratories portal, while the ESA SSEP project (SuperSites exploitation plateform) is developing as an Helix Nebula usecase. Meanwhile, operational use of space data for emergency management is in constant progress, within the Copernicus services. This rich activity is still leaving some gaps between the data availability and its scientific use, either for technical reasons (big data issues) or due to the need for a better support in term of expert knowledge on the data, of software availability, or of data cost. French infrastructures for data distribution are organized around National Observatory Services (in situ data), scientific services participating to the International association of geodesy data centres and wider research infrastructures such as the Réseau Sismologique et géodésique Français (RESIF) that is contributing to EPOS. The need for thematic cooperative platforms has been underlined over tha last years. In 2009, after a scientific prospective of the French national space agency (CNES) it becomes clear the urgent need to create thematic centres designed to federate the scientific community of Earth observation. Four thematic data centres are currently developing in France in the field of ocean , atmosphere, critical zone and solid Earth sciences. For Solid Earth research, the project - named ForM@Ter - was initiated at the beginning of 2012 to design, with the scientific community, the perimeter, structure and functions of such a thematic centre. It was launched by the CNES and the National

    Full Text Available Physical Therapy is a profession which development and conceptual framework have been performed in the twentieth century. One of the major challenges of Physical Therapy in the twenty-first century is to identify the intellectual basis of its scientific domain. The aim of the present paper is to analyze the evolution of Physical Therapy research throughout scientific literature published in Web of Science (WoS and Scopus databases. In order to perform the analysis, WoS and Scopus bibliographic databases were used to download all records. A set of journals with overall topics in Physical Therapy discipline with the largest history in the Journal Citation Report were selected: Physiotherapy, Physical Therapy, and Australian Journal of Physiotherapy/Journal of Physiotherapy. The bibliometric tool SciMAT was employed to perform a science mapping analysis in order to detect and visualize the research themes and their evolution across three periods: 1951–1984, 1985–2000, and 2001–2013. The analysis carried out shows that Physical Therapy research field is mainly divided into nine thematic areas: Middle-Aged People, Muscle Function Alterations and Recovery, Health Education, Gait and Biomechanics, Central Nervous System, Heart Rate and Exercise, Diagnosis, Low Back Pain, and Animals. In conclusion, Physical Therapy citations and production are primarily focused on two large thematic areas, diseases that involve middle-aged population and muscle function and its alterations. Results can be used to provide a historical perspective on research conducted in this emerging field and to provide a scientific evidence-based practice model on which future studies can be built.

    Full Text Available This study performed two phases of analysis to shed light on the performance and thematic evolution of China's quantum cryptography (QC research. First, large-scale research publication metadata derived from QC research published from 2001-2017 was used to examine the research performance of China relative to that of global peers using established quantitative and qualitative measures. Second, this study identified the thematic evolution of China's QC research using co-word cluster network analysis, a computational science mapping technique. The results from the first phase indicate that over the past 17 years, China's performance has evolved dramatically, placing it in a leading position. Among the most significant findings is the exponential rate at which all of China's performance indicators (i.e., Publication Frequency, citation score, H-index are growing. China's H-index (a normalized indicator has surpassed all other countries' over the last several years. The second phase of analysis shows how China's main research focus has shifted among several QC themes, including quantum-key-distribution, photon-optical communication, network protocols, and quantum entanglement with an emphasis on applied research. Several themes were observed across time periods (e.g., photons, quantum-key-distribution, secret-messages, quantum-optics, quantum-signatures; some themes disappeared over time (e.g., computer-networks, attack-strategies, bell-state, polarization-state, while others emerged more recently (e.g., quantum-entanglement, decoy-state, unitary-operation. Findings from the first phase of analysis provide empirical evidence that China has emerged as the global driving force in QC. Considering China is the premier driving force in global QC research, findings from the second phase of analysis provide an understanding of China's QC research themes, which can provide clarity into how QC technologies might take shape.

    Vogelmann, James E.; Helder, Dennis; Morfitt, Ron; Choate, Michael J.; Merchant, James W.; Bulley, Henry

    2001-01-01

    The Thematic Mapper (TM) instruments onboard Landsats 4 and 5 provide high-quality imagery appropriate for many different applications, including land cover mapping, landscape ecology, and change detection. Precise calibration was considered to be critical to the success of the Landsat 7 mission and, thus, issues of calibration were given high priority during the development of the Enhanced Thematic Mapper Plus (ETM+). Data sets from the Landsat 5 TM are not routinely corrected for a number of radiometric and geometric artifacts, including memory effect, gain/bias, and interfocal plane misalignment. In the current investigation, the effects of correcting vs. not correcting these factors were investigated for several applications. Gain/bias calibrations were found to have a greater impact on most applications than did memory effect calibrations. Correcting interfocal plane offsets was found to have a moderate effect on applications. On June 2, 1999, Landsats 5 and 7 data were acquired nearly simultaneously over a study site in the Niobrara, NE area. Field radiometer data acquired at that site were used to facilitate crosscalibrations of Landsats 5 and 7 data. Current findings and results from previous investigations indicate that the internal calibrator of Landsat 5 TM tracked instrument gain well until 1988. After this, the internal calibrator diverged from the data derived from vicarious calibrations. Results from this study also indicate very good agreement between prelaunch measurements and vicarious calibration data for all Landsat 7 reflective bands except Band 4. Values are within about 3.5% of each other, except for Band 4, which differs by 10%. Coefficient of variation (CV) values derived from selected targets in the imagery were also analyzed. The Niobrara Landsat 7 imagery was found to have lower CV values than Landsat 5 data, implying that lower levels of noise characterize Landsat 7 data than current Landsat 5 data. It was also found that following

    2001-07-01

    This study compared the responses of dissociative inpatients and general inpatient psychiatric controls on the Thematic Apperception Test (TAT; Murray, 1943). We found the stories of dissociative participants to be characterized by a greater interpersonal distance and more trauma and dissociation responses than those of the controls. No significant differences were found regarding total number of emotional references, although references to positive emotions were almost nonexistent for the dissociative group. A post hoc analysis of the data found the testing behaviors of dissociative participants to be characterized by switching, trance states, intrainterview amnesias, and affectively loaded card rejections. Questions were raised regarding the relevancy of the findings to clinical practice and how they might explain some of the controversies surrounding the diagnosis of dissociative identity disorder (DID).

    1986-01-01

    The potential of Thematic Mapper Simulator (TMS) data for sensing forest structure information has been explored by principal components and feature selection techniques. In a survey of forest structural properties conducted for 123 field sites of the Sequoia National Park, the canopy closure could be well estimated (r = 0.62 to 0.69) by a variety of channel bands and band ratios, without reference to the forest type. Estimation of the basal area was less successful (r = 0.51 or less) on the average, but could be improved for certain forest types when data were stratified by floristic composition. To achieve such a stratification, individual sites were ordinated by a detrended correspondence analysis based on the canopy of dominant species. The analysis of forest structure in the Sequoia data suggests that total basal area can be best predicted in stands of lower density, and in younger even-aged managed stands.

    1995-01-01

    Landsat Thematic Mapper (TM) data were used to evaluate young conifer stands in the western Cascade Mountains of Oregon. Regression and correlation analyses were used to describe the relationships between TM band values and age of young Douglas-fir stands (2 to 35 years old). Spectral data from well regenerated Douglas-fir stands were compared to those of poorly regenerated conifer stands. TM bands 1, 2, 3, 5, 6, and 7 were inversely correlated with the age (r greater than or equal to -0.80) of well regenerated Douglas-fir stands. Overall, the 'structural index' (TM 4/5 ratio) had the highest correlation to age of Douglas-fir stands (r = 0.96). Poorly regenerated stands were spectrally distinct from well regenerated Douglas-fir stands after the stands reached an age of approximately 15 years.

    Cyberstalking (CS) can have major psychosocial impacts on individuals. Victims report a number of serious consequences of victimization such as increased suicidal ideation, fear, anger, depression, and post traumatic stress disorder (PTSD) symptomology. Research is largely limited to quantitative outcome research. This study examines the diversity of experiences reported by people who define themselves as having been cyberstalked. Thematic analysis was used to explore 100 CS victim narratives, gathered by means of an online survey questionnaire designed to capture structured text responses. Five emergent themes were evident in the data: control and intimidation; determined offender; development of harassment; negative consequences; and lack of support. Findings identify similarities and differences to traditional stalking, along with the necessity of support for victims and illustration of the negative impacts this form of harassment produces.

    Plants and their green cousins cyanobacteria and algae use sunlight to drive the chemistry that lets them grow, survive, and perform an amazing range of biochemical reactions. The ability of these organisms to use a freely available energy source makes them attractive as sustainable and renewable platforms for more than just food production. They are also a source of metabolic tools for engineering microbes for "green" chemistry. This Thematic Minireview Series discusses how green organisms capture light and protect their photosynthetic machinery from too much light; new structural snapshots of the clock complex that orchestrates signaling during the light/dark cycle; challenges for improving stress responses in crops; harnessing cyanobacteria as biofactories; and efforts to engineer microbes for "green" biopolymer production. © 2018 Jez.

    1978-01-01

    Ceramic incensarios were an important component of ritual paraphernalia in the Palenque region. Tubular flanged cylinders - stands or supports for receptacles in which the incense was actually burned - were highly embellished. The primary concern is with these iconographically-rich objects, focusing on variations in thematic presentation and in paste composition. The latter, mineralogical and chemical composition, has significance in that it enables differentiation among centers of production, leading to a better understanding of where clay resources were procured and, inferentially, where the incensarios were manufactured. An attempt is being made to determine if incensarios of Palenque style were manufactured at a single or at multiple sites, if Palenque itself was a production center, and what can be inferred about trading or distributional patterns of these specialized objects.

    2017-07-01

    This study examines the subjective experience of living with epilepsy by thematically analyzing participants' written accounts of their condition. Writing is seen as an individual act allowing for private exploration, reflection and expression of thoughts and feelings. Participants (n=20) were recruited from a United Kingdom hospital and from membership-led organizations for individuals living with seizures. Participants were asked to produce four pieces of writing: 1) about their thoughts and feelings about their condition; 2) a letter to their condition; 3) a letter to their younger self; and 4) about a personal value. All writings were analyzed thematically using a theory- and data-driven approach. Five main-themes and 22 sub-themes emerged from the data. Theme 1: 'seizure onset' demonstrated that the development of seizures and subsequent diagnosis was an important event that could change an individuals' identity. Theme 2: 'seizure symptoms' revealed participants externalized their seizures as an intrusive agent with a constant presence in their lives. Theme 3: 'treatment and outcome' reflected medication as an essential means to controlling seizures with subsequent side effects being perceived as a compromise. Theme 4: 'living with epilepsy' explored the consequences of the condition including restrictions and stigma. Theme 5: 'displays of coping' demonstrated that, for the most part, participants were keen to present themselves as living well with epilepsy. The results add to the growing research applying qualitative methodologies to investigate the phenomenology of epilepsy. Qualitative research can improve our understanding and awareness of the condition, as well as inform clinical practice. Copyright © 2017 Elsevier Inc. All rights reserved.

  15. Rethinking Prefigurative Politics: Introduction to the Special Thematic Section

    Directory of Open Access Journals (Sweden)

    Flora Cornish

    2016-05-01

    Full Text Available This special thematic section responds to the 21st century proliferation of social movements characterised by the slogans ‘another world is possible’ and ‘be the change you want to see’. It explores prefigurative politics as a means of instantiating radical social change in a context of widening global inequalities, climate change, and the crises and recoveries of neoliberal global capitalism. ‘Prefigurative politics’ refers to a range of social experiments that both critique the status quo and offer alternatives by implementing radically democratic practices in pursuit of social justice. This collection of articles makes the case for psychologists to engage with prefigurative politics as sites of psychological and social change, in the dual interests of understanding the world and changing it. The articles bridge psychology and politics in three different ways. One group of articles brings a psychological lens to political phenomena, arguing that attention to the emotional, relational and intergroup dynamics of prefigurative politics is required to understand their trajectories, challenges, and impacts. A second group focuses a political lens on social settings traditionally framed as psychological sites of well-being, enabling an understanding of their political nature. The third group addresses the ‘border tensions’ of the psychological and the political, contextualising and historicising the instantiation of prefigurative ideals and addressing tensions that arise between utopian ideals and various internal and external constraints. This introduction to the special section explores the concept and contemporary debates concerning prefigurative politics, outlines the rationale for a psychological engagement with this phenomenon, and presents the articles in the special thematic section. The general, prefigurative, aim is to advance psychology’s contribution to rethinking and remaking the world as it could be, not only

    The current study examined whether thematic relations of the novel words could be acquired via descriptive episodes, and if yes, whether it could be generalized to thematically related words in a different scenario. In Experiment 1, a lexical decision task was used where the novel words served as primes for target words in four conditions: (1) corresponding concepts of the novel words, (2) thematically related words in the same episodes as that in learning condition, (3) thematically related words in different episodes, or (4) unrelated words served as targets. Event related potentials elicited by the targets revealed that compared to the unrelated words, the corresponding concepts and thematically related words in the same episodes elicited smaller N400s with a frontal-central distribution, whereas the thematically related words in different episodes elicited an enhanced late positive component. Experiment 2 further showed a priming effect of the corresponding concepts on the thematically related words in the same episodes as well as in a different episode, indicating that the absence of a priming effect of the learned novel words on the thematically related words in different episode could not be attributed to inappropriate selection of thematically related words in the two conditions. These results indicate that only the corresponding concepts and the thematically related words in the learning episodes were successfully primed, whereas the thematic association between the novel words and the thematically related words in different scenarios could only be recognized in a late processing stage. Our findings suggest that thematic knowledge of novel words is organized via separate scenarios, which are represented in a clustered manner in the semantic network.

  17. Drawing Road Networks with Mental Maps.

    Tourist and destination maps are thematic maps designed to represent specific themes in maps. The road network topologies in these maps are generally more important than the geometric accuracy of roads. A road network warping method is proposed to facilitate map generation and improve theme representation in maps. The basic idea is deforming a road network to meet a user-specified mental map while an optimization process is performed to propagate distortions originating from road network warping. To generate a map, the proposed method includes algorithms for estimating road significance and for deforming a road network according to various geometric and aesthetic constraints. The proposed method can produce an iconic mark of a theme from a road network and meet a user-specified mental map. Therefore, the resulting map can serve as a tourist or destination map that not only provides visual aids for route planning and navigation tasks, but also visually emphasizes the presentation of a theme in a map for the purpose of advertising. In the experiments, the demonstrations of map generations show that our method enables map generation systems to generate deformed tourist and destination maps efficiently.

  18. Comparing the temporal dynamics of thematic and taxonomic processing using event-related potentials.

    Directory of Open Access Journals (Sweden)

    Olivera Savic

    Full Text Available We report the results of a study comparing the temporal dynamics of thematic and taxonomic knowledge activation in a picture-word priming paradigm using event-related potentials. Although we found no behavioral differences between thematic and taxonomic processing, ERP data revealed distinct patterns of N400 and P600 amplitude modulation for thematic and taxonomic priming. Thematically related target stimuli elicited less negativity than taxonomic targets between 280-460 ms after stimulus onset, suggesting easier semantic processing of thematic than taxonomic relationships. Moreover, P600 mean amplitude was significantly increased for taxonomic targets between 520-600 ms, consistent with a greater need for stimulus reevaluation in that condition. These results offer novel evidence in favor of a dissociation between thematic and taxonomic thinking in the early phases of conceptual evaluation.

    Subjective decisions of thematic and spatial resolutions in characterizing environmental heterogeneity may affect the characterizations of spatial pattern and the simulation of occurrence and rate of ecological processes, and in turn, model-based tree species distribution. Thus, this study quantified the importance of thematic and spatial resolutions, and their interaction in predictions of tree species distribution (quantified by species abundance). We investigated how model-predicted species abundances changed and whether tree species with different ecological traits (e.g., seed dispersal distance, competitive capacity) had different responses to varying thematic and spatial resolutions. We used the LANDIS forest landscape model to predict tree species distribution at the landscape scale and designed a series of scenarios with different thematic (different numbers of land types) and spatial resolutions combinations, and then statistically examined the differences of species abundance among these scenarios. Results showed that both thematic and spatial resolutions affected model-based predictions of species distribution, but thematic resolution had a greater effect. Species ecological traits affected the predictions. For species with moderate dispersal distance and relatively abundant seed sources, predicted abundance increased as thematic resolution increased. However, for species with long seeding distance or high shade tolerance, thematic resolution had an inverse effect on predicted abundance. When seed sources and dispersal distance were not limiting, the predicted species abundance increased with spatial resolution and vice versa. Results from this study may provide insights into the choice of thematic and spatial resolutions for model-based predictions of tree species distribution.

    Digital processed aircraft-acquired thematic mapping simulator (TMS) data collected during the winter season over a forested site in southern Mississippi are presented to investigate the utility of TMS data for use in forest inventories and monitoring. Analyses indicated that TMS data are capable of delineating the mixed forest land cover type to an accuracy of 92.5 % correct. The accuracies associated with river bottom forest and pine forest were 95.5 and 91.5 % correct. The accuracies associated with river bottom forest and pine forest were 95.5 and 91.5 % correct, respectively. The figures reflect the performance for products produced using the best subset of channels for each forest cover type. It was found that the choice of channels (subsets) has a significant effect on the accuracy of classification produced, and that the same channels are not the most desirable for all three forest types studied. Both supervised and unsupervised spectral signature development techniques are evaluated; the unsupervised methods proved unacceptable for the three forest types considered.

    Full Text Available Despite unprecedented access to information and diffusion of knowledge across the globe, the bulk of work in mainstream psychological science still reflects and promotes the interests of a privileged minority of people in affluent centers of the modern global order. Compared to other social science disciplines, there are few critical voices who reflect on the Euro-American colonial character of psychological science, particularly its relationship to ongoing processes of domination that facilitate growth for a privileged minority but undermine sustainability for the global majority. Moved by mounting concerns about ongoing forms of multiple oppression (including racialized violence, economic injustice, unsustainable over-development, and ecological damage, we proposed a special thematic section and issued a call for papers devoted to the topic of "decolonizing psychological science". In this introduction to the special section, we first discuss two perspectives—liberation psychology and cultural psychology—that have informed our approach to the topic. We then discuss manifestations of coloniality in psychological science and describe three approaches to decolonization—indigenization, accompaniment, and denaturalization—that emerge from contributions to the special section. We conclude with an invitation to readers to submit their own original contributions to an ongoing effort to create an online collection of digitally linked articles on the topic of decolonizing psychological science.

    To examine posts on Internet discussion groups related to vasectomies, and identify common ideas through a structured theme analysis. Internet discussion boards were identified using the search term "vasectomy." Three discussion boards were identified as having the most posts and were chosen for analysis. Using an iterative and structured analysis process, each post was analyzed using thematic analysis in 3 steps (open coding, axial coding, and selective coding) to determine common themes. A total of 129 posts were analyzed. The most common posts related to changes in sexual function after vasectomy. The second most common theme was pain after vasectomy. There were also posts about considerations before vasectomy, planning for postvasectomy care, what to expect after vasectomy, potential issues after vasectomy and how to manage these, and feelings about vasectomy. Some of the information present did not have a factual basis. Posts dedicated to postvasectomy pain and sexual dysfunction were of the highest quantity. There was no medical provider input to these discussion boards. Educational efforts should be targeted to these areas and should include a health-care professional. Copyright © 2017 Elsevier Inc.

    2018-03-02

    Dysmenorrhea is highly prevalent and is the leading cause of absence from school and work among women of reproductive age. Evidence suggests that dysmenorrhea may also be a risk factor for other chronic pain conditions. Limited research has examined women's experience with dysmenorrhea using qualitative data. Research is warranted to address issues and needs that are important from women's own perspectives. Therefore, the purpose of this study was to describe women's salient thoughts about their experiences of dysmenorrhea. We analyzed data collected from an open-ended question within a cross-sectional survey study conducted in the United States. Using qualitative thematic analysis, free text responses to a question asking women to share their experience with dysmenorrhea were analyzed. The sample consisted of 225 women who provided valid responses to the open-ended question. Six themes were identified: (1) The dysmenorrhea symptom experience varied among women; (2) The dysmenorrhea symptom experience varied across time, (3) A variety of factors influenced the dysmenorrhea symptom experience, (4) Dysmenorrhea symptoms could have a negative impact on the women's daily lives, (5) Dysmenorrhea was not seen as a legitimate health issue by the women, health care providers, or society, and (6) Treatment for women with dysmenorrhea varied in acceptability and effectiveness. The findings of this study have important implications for dysmenorrhea symptom assessment and the development of personalized interventions to support dysmenorrhea management.

    1984-01-01

    Landsat-4 Thematic Mapper data of Washington, DC, Harrisburg, PA, and Salton Sea, CA were analyzed to determine geometric integrity and conformity of the data to known earth surface geometry. Several tests were performed. Intraband correlation and interband registration were investigated. No problems were observed in the intraband analysis, and aside from indications of slight misregistration between bands of the primary versus bands of the secondary focal planes, interband registration was well within the specified tolerances. A substantial number of ground control points were found and used to check the images' conformity to the Space Oblique Mercator (SOM) projection of their respective areas. The means of the residual offsets, which included nonprocessing related measurement errors, were close to the one pixel level in the two scenes examined. The Harrisburg scene residual mean was 28.38 m (0.95 pixels) with a standard deviation of 19.82 m (0.66 pixels), while the mean and standard deviation for the Salton Sea scene were 40.46 (1.35 pixels) and 30.57 m (1.02 pixels), respectively. Overall, the data were judged to be a high geometric quality with errors close to those targeted by the TM sensor design specifications.

    Introduction Various forms of social media are used by many mothers to maintain social ties and manage the stress associated with their parenting roles and responsibilities. 'Mommy blogging' as a specific type of social media usage is a common and growing phenomenon, but little is known about mothers' blogging-related experiences and how these may contribute to their wellbeing. This exploratory study investigated the blogging-related motivations and goals of Australian mothers. Methods An online survey was emailed to members of an Australian online parenting community. The survey included open-ended questions that invited respondents to discuss their motivations and goals for blogging. A thematic analysis using a grounded approach was used to analyze the qualitative data obtained from 235 mothers. Results Five primary motivations for blogging were identified: developing connections with others, experiencing heightened levels of mental stimulation, achieving self-validation, contributing to the welfare of others, and extending skills and abilities. Discussion These motivations are discussed in terms of their various properties and dimensions to illustrate how these mothers appear to use blogging to enhance their psychological wellbeing.

    To identify the range of emotional labour employed by healthcare professionals in a healthcare setting and implications of this for staff and organisations. In a healthcare setting, emotional labour is the act or skill involved in the caring role, in recognizing the emotions of others and in managing our own. A thematic synthesis of qualitative studies which included emotion work theory in their design, employed qualitative methods and were situated in a healthcare setting. The reporting of the review was informed by the ENTREQ framework. 6 databases were searched between 1979-2014. Studies were included if they were qualitative, employed emotion work theory and were written in English. Papers were appraised and themes identified. Thirteen papers were included. The reviewed studies identified four key themes: (1) The professionalization of emotion and gendered aspects of emotional labour; (2) Intrapersonal aspects of emotional labour - how healthcare workers manage their own emotions in the workplace; (3) Collegial and organisational sources of emotional labour; (4) Support and training needs of professionals This review identified gendered, personal, organisational, collegial and socio-cultural sources of and barriers to emotional labour in healthcare settings. The review highlights the importance of ensuring emotional labour is recognized and valued, ensuring support and supervision is in place to enable staff to cope with the varied emotional demands of their work. © 2015 John Wiley & Sons Ltd.

  8. Thematic minireview series: cell biology of G protein signaling.

    Dohlman, Henrik G

    2015-03-13

    This thematic series is on the topic of cell signaling from a cell biology perspective, with a particular focus on G proteins. G protein-coupled receptors (GPCRs, also known as seven-transmembrane receptors) are typically found at the cell surface. Upon agonist binding, these receptors will activate a GTP-binding G protein at the cytoplasmic face of the plasma membrane. Additionally, there is growing evidence that G proteins can also be activated by non-receptor binding partners, and they can signal from non-plasma membrane compartments. The production of second messengers at multiple, spatially distinct locations represents a type of signal encoding that has been largely neglected. The first minireview in the series describes biosensors that are being used to monitor G protein signaling events in live cells. The second describes the implementation of antibody-based biosensors to dissect endosome signaling by G proteins and their receptors. The third describes the function of a non-receptor, cytoplasmic activator of G protein signaling, called GIV (Girdin). Collectively, the advances described in these articles provide a deeper understanding and emerging opportunities for new pharmacology. © 2015 by The American Society for Biochemistry and Molecular Biology, Inc.

    Full Text Available The main objective of this research was to determine the types of appeals used in telecommunication advertisement, explain how the themes and appeals used in the advertisement were presented, and see how it could attract subscribers despite the challenges in the industry. Qualitative content analysis method was used to provide a thematic analysis of the messages contained in numbers of selected advertisements shown on YouTube, social media, and television stations in Nigeria. The findings show that the advertisements adopt emotional (love, celebrity appearance, music, comedy, humor, drama and rational appeal to persuade the subscribers. Moreover, the themes of the advertisements focus on accomplishment and improve service regarding call charges, network coverage, network quality, and customer service. It further shows that these strategies employed by the telecommunication industry are capable of influencing the choice of the subscribers in the Nigerian market. The research recommends and concludes that companies should consistently engage the appeals used with more emphasis on the emotional appeal to retain their size of the market.

    2014-11-01

    Food practices are embedded in everyday life and social relationships. In youth nutrition promotion little attention is awarded to this centrality of food practices, yet it may play a pivotal role for young people's overall health and wellbeing beyond the calories food provides. Limited research is available explicitly investigating how food practices affect social relationships. The aim of this synthesis was therefore to find out how young people use everyday food practices to build, strengthen, and negotiate their social relationships. Using a thematic synthesis approach, we analysed 26 qualitative studies exploring young people's food practices. Eight themes provided insight into the ways food practices affected social relationships: caring, talking, sharing, integrating, trusting, reciprocating, negotiating, and belonging. The results showed that young people use food actively to foster connections, show their agency, and manage relationships. This synthesis provides insight into the settings of significance for young people where more research could explore the use of food in everyday life as important for their social relationships. A focus on social relationships could broaden the scope of nutrition interventions to promote health in physical and psychosocial dimensions. Areas for future research are discussed.

    2008-01-01

    The Landsat-5 (L5) Thematic Mapper (TM) detectors of the short wave infrared (SWIR) bands 5 and 7 are maintained on cryogenic temperatures to minimize thermal noise and allow adequate detection of scene energy. Over the instrument's lifetime, gain oscillations are observed in these bands that are caused by an ice-like contaminant that gradually builds up on the window of a dewar that houses these bands' detectors. This process of icing, an effect of material outgassing in space, is detected and characterized through observations of Internal Calibrator (IC) data. Analyses of IC data indicated three to five percent uncertainty in absolute gain estimates due to this icing phenomenon. The thin-film interference lifetime models implemented in the image product generation systems at the U.S. Geological Survey (USGS) Center for Earth Resources Observation and Science (EROS) successfully remove up to 80 percent of the icing effects for the image acquisition period from the satellite's launch in 1984 until 2001; however, their correction ability was found to be much lower for the time thereafter. This study concentrates on improving the estimates of the contaminant film growth rate and the associated change in the period of gain oscillations. The goal is to provide model parameters with the potential to correct 70 to 80 percent of gain uncertainties caused by outgassing effects in L5 TM bands 5 and 7 over the instrument's entire lifetime. ?? 2007 IEEE.

    Many women quit smoking during pregnancy, but relapse after the baby is born. To understand why and identify ways of preventing this, this study reviewed the qualitative literature on women's experience of postpartum smoking relapse. A systematic review of qualitative studies and process evaluations of trials. We undertook a thematic synthesis of published qualitative data. We screened 1336 papers. Twenty-two papers reporting on 16 studies were included, reporting on the views of 1031 postpartum women. Factors affecting relapse and barriers and facilitators to relapse prevention were identified around the key themes of beliefs, social influences, motivation, physiological factors and identity. Women's beliefs about smoking as a means of coping with stress and the need for social support, especially from a partner, emerged as important. Extrinsic motivation to quit during the pregnancy (for the health of the fetus) appeared to be a factor in prompting relapse after the baby was born. During the immediate postpartum period women believed that physiological changes influence cigarette cravings. The stress of caring for a newborn, sleeplessness and adjusting to a new mothering identity were also reported to be important. Among women who quit smoking during pregnancy, those who relapse postpartum talk commonly about no longer needing to protect the baby and the effects of stress. Partner support and a sense of changed identity are cited as factors preventing relapse. © 2015 Society for the Study of Addiction.

    1986-01-01

    Landsat Thematic Mapper (TM) data collected for Imperial Valley, California in December, 1982 were digitally examined to assess their utility to distinguish among agricultural and other land-covers. Statistics for thirty-seven training sites representing a variety of crops plus urban, water and desert land-covers were obtained and analyzed using transformed divergence (TD) calculations. TD values were employed to assess intraclass variability and the best bands for classification. Four subscenes were selected for clustering or unsupervised signature extraction. These areas were agriculture, urban, desert and water land-covers. The number of clusters for these subscenes were examined and the best TM bands for interclass separability were identified. The results of the clustering and training site analyses for interclass separability were compared. The TM data were useful for the digital delimitation of most crops and other cover types in this analysis. Four bands of data are adequate for classification with the best results obtained by the selection of one band from each of the available portions of the electromagnetic spectrum. Different band combinations are best for various land-cover intraclass separability.

    The study of cytoskeletal polymers has been an active area of research for more than 70 years. However, despite decades of pioneering work by some of the brightest scientists in biochemistry, cell biology, and physiology, many central questions regarding the polymers themselves are only now starting to be answered. For example, although it has long been appreciated that the actin cytoskeleton provides contractility and couples biochemical responses with mechanical stresses in cells, only recently have we begun to understand how the actin polymer itself responds to mechanical loads. Likewise, although it has long been appreciated that the microtubule cytoskeleton can be post-translationally modified, only recently have the enzymes responsible for these modifications been characterized, so that we can now begin to understand how these modifications alter the polymerization and regulation of microtubule structures. Even the septins in eukaryotes and the cytoskeletal polymers of prokaryotes have yielded new insights due to recent advances in microscopy techniques. In this thematic series of minireviews, these topics are covered by some of the very same scientists who generated these recent insights, thereby providing us with an overview of the State of the Cytoskeleton in 2015. © 2015 by The American Society for Biochemistry and Molecular Biology, Inc.

    2010-07-01

    The purpose of this study was to explore the complexities (including harms and benefits) of international health electives (IHEs) involving medical trainees. This exploration contributes to the ongoing debate about the goals and implications of IHEs for medical trainees. This qualitative study used anonymous, one-to-one, semi-structured interviews. All participants had previous international health experiences. Between September 2007 and March 2008, we interviewed a convenience sample of health care professionals (n=10) and medical trainees (n=10). Using a modified grounded theory methodology, we carried out cycles of data analysis in conjunction with data collection in an iterative and constant comparison process. The study's thematic structure was finalised when theme saturation was achieved. Participants described IHEs in both negative and positive terms. IHEs were described as unsustained short-term contributions that lacked clear educational objectives and failed to address local community needs. Ethical dilemmas were described as IHE challenges. Participants reflected that many IHEs included aspects of medical tourism and the majority of participants described the IHE in negative terms. However, a few participants acknowledged the benefits of the IHE. Specifically, it was seen as an introduction to a career in global health and as a potential foundation for more sustainable projects with positive host community impacts. Finally, despite similar understandings among participants, self-awareness of medical tourism was low. International health electives may include potential harms and benefits for both the trainee and the host community. Educational institutions should encourage and support structured IHEs for trainee participation. We recommend that faculties of medicine and global health educators establish pre-departure training courses for trainees and that IHE opportunities have sufficient structures in place to mitigate the negative effects of medical

    Performance requirements regarding geometric accuracy have been defined in terms of end product goals, but until recently no precise details have been given concerning the conditions under which that accuracy is to be achieved. In order to achieve higher spatial and spectral resolutions, the Thematic Mapper (TM) sensor was designed to image in both forward and reverse mirror sweeps in two separate focal planes. Both hardware and software have been augmented and changed during the course of the Landsat TM developments to achieve improved geometric accuracy. An investigation has been conducted to determine if the TM meets the National Map Accuracy Standards for geometric accuracy at larger scales. It was found that TM imagery, in terms of geometry, has come close to, and in some cases exceeded, its stringent specifications.

    EPOS Thematic Core Service ANTHROPOGENIC HAZARDS (TCS AH) aims to integrate distributed research infrastructures (RI) to facilitate and stimulate research on anthropogenic hazards (AH) especially those associated with the exploration and exploitation of geo-resources. The innovative element is the uniqueness of the integrated RI which comprises two main deliverables: (1) Exceptional datasets, called "episodes", which comprehensively describe a geophysical process; induced or triggered by human technological activity, posing hazard for populations, infrastructure and the environment, (2) Problem-oriented, bespoke services uniquely designed for the discrimination and analysis of correlations between technology, geophysical response and resulting hazard. These objectives will be achieved through the Science-Industry Synergy (SIS) built by EPOS WG10, ensuring bi-directional information exchange, including unique and previously unavailable data furnished by industrial partners. The Episodes and services to be integrated have been selected using strict criteria during the EPOS PP. The data are related to a wide spectrum of inducing technologies, with seismic/aseismic deformation and production history as a minimum data set requirement and the quality of software services is confirmed and referenced in literature. Implementation of TCS AH is planned for four years and requires five major activities: (1) Strategic Activities and Governance: will define and establish the governance structure to ensure the long-term sustainability of these research infrastructures for data provision through EPOS. (2) Coordination and Interaction with the Community: will establish robust communication channels within the whole TCS AH community while supporting global EPOS communication strategy. (3) Interoperability with EPOS Integrated Core Service (ICS) and Testing Activities: will coordinate and ensure interoperability between the RIs and the ICS. Within this modality a functional e

    2017-12-01

    This thematic collection contains eight papers mostly presented at the 2016 AOGS meeting in Beijing. Four papers describe historical earthquake studies in Europe, Japan, and China; one paper uses modern instrumental data to examine the effect of giant earthquakes on the seismicity rate; and three papers describe paleoseismological studies using tsunami deposit in Japan, marine terraces in Philippines, and active faults in Himalayas. Hammerl (Geosci Lett 4:7, 2017) introduced historical seismological studies in Austria, starting from methodology which is state of the art in most European countries, followed by a case study for an earthquake of July 17, 1670 in Tyrol. Albini and Rovida (Geosci Lett 3:30, 2016) examined 114 historical records for the earthquake on April 6, 1667 on the east coast of the Adriatic Sea, compiled 37 Macroseismic Data Points, and estimated the epicenter and the size of the earthquake. Matsu'ura (Geosci Lett 4:3, 2017) summarized historical earthquake studies in Japan which resulted in about 8700 Intensity Data Points, assigned epicenters for 214 earthquakes between AD 599 and 1872, and estimated focal depth and magnitudes for 134 events. Wang et al. (Geosci Lett 4:4, 2017) introduced historical seismology in China, where historical earthquake archives include about 15,000 sources, and parametric catalogs include about 1000 historical earthquakes between 2300 BC and AD 1911. Ishibe et al. (Geosci Lett 4:5, 2017) tested the Coulomb stress triggering hypothesis for three giant (M 9) earthquakes that occurred in recent years, and found that at least the 2004 Sumatra-Andaman and 2011 Tohoku earthquakes caused the seismicity rate change. Ishimura (2017) re-estimated the ages of 11 tsunami deposits in the last 4000 years along the Sanriku coast of northern Japan and found that the average recurrence interval of those tsunamis as 350-390 years.

The 218 individual flight lines composing the Afghanistan dataset, covering more than 438,000 square kilometers, were georeferenced to a mosaic of orthorectified Landsat images. The HyMap data were converted from radiance to reflectance using a radiative transfer program in combination with ground-calibration sites and a network of cross-cutting calibration flight lines. The U.S. Geological Survey Material Identification and Characterization Algorithm (MICA) was used to generate two thematic maps of surface minerals: a map of iron-bearing minerals and other materials, which have their primary absorption features at the shorter wavelengths of the reflected solar wavelength range, and a map of carbonates, phyllosilicates, sulfates, altered minerals, and other materials, which have their primary absorption features at the longer wavelengths of the reflected solar wavelength range. In contrast to the original version, version 2 of these maps is provided at full resolution of 23-meter pixel size. The thematic maps, MICA summary images, and the material fit and depth images are distributed in digital files linked to this report, in a format readable by remote sensing software and Geographic Information Systems (GIS). The digital files can be downloaded from http://pubs.usgs.gov/ds/787/downloads/.

  9. Planetary Geologic Mapping Handbook - 2009

    Tanaka, K. L.; Skinner, J. A.; Hare, T. M.

    2009-01-01

    Geologic maps present, in an historical context, fundamental syntheses of interpretations of the materials, landforms, structures, and processes that characterize planetary surfaces and shallow subsurfaces (e.g., Varnes, 1974). Such maps also provide a contextual framework for summarizing and evaluating thematic research for a given region or body. In planetary exploration, for example, geologic maps are used for specialized investigations such as targeting regions of interest for data collection and for characterizing sites for landed missions. Whereas most modern terrestrial geologic maps are constructed from regional views provided by remote sensing data and supplemented in detail by field-based observations and measurements, planetary maps have been largely based on analyses of orbital photography. For planetary bodies in particular, geologic maps commonly represent a snapshot of a surface, because they are based on available information at a time when new data are still being acquired. Thus the field of planetary geologic mapping has been evolving rapidly to embrace the use of new data and modern technology and to accommodate the growing needs of planetary exploration. Planetary geologic maps have been published by the U.S. Geological Survey (USGS) since 1962 (Hackman, 1962). Over this time, numerous maps of several planetary bodies have been prepared at a variety of scales and projections using the best available image and topographic bases. Early geologic map bases commonly consisted of hand-mosaicked photographs or airbrushed shaded-relief views and geologic linework was manually drafted using mylar bases and ink drafting pens. Map publishing required a tedious process of scribing, color peel-coat preparation, typesetting, and photo-laboratory work. Beginning in the 1990s, inexpensive computing, display capability and user-friendly illustration software allowed maps to be drawn using digital tools rather than pen and ink, and mylar bases became obsolete

    EPOS, the European Plate Observing System, is a long-term plan to facilitate the integrated use of data, data products, software and services, available from distributed Research Infrastructures (RI), for solid Earth science in Europe. Indeed, EPOS integrates a large number of existing European RIs belonging to several fields of the Earth science, from seismology to geodesy, near fault and volcanic observatories as well as anthropogenic hazards. The EPOS vision is that the integration of the existing national and trans-national research infrastructures will increase access and use of the multidisciplinary data recorded by the solid Earth monitoring networks, acquired in laboratory experiments and/or produced by computational simulations. The establishment of EPOS will foster the interoperability of products and services in the Earth science field to a worldwide community of users. Accordingly, the EPOS aim is to integrate the diverse and advanced European Research Infrastructures for solid Earth science, and build on new e-science opportunities to monitor and understand the dynamic and complex solid-Earth System. One of the EPOS Thematic Core Services (TCS), referred to as Satellite Data, aims at developing, implementing and deploying advanced satellite data products and services, mainly based on Copernicus data (namely Sentinel acquisitions), for the Earth science community. This work intends to present the technological enhancements, fostered by EPOS, to deploy effective satellite services in a harmonized and integrated way. In particular, the Satellite Data TCS will deploy five services, EPOSAR, GDM, COMET, 3D-Def and MOD, which are mainly based on the exploitation of SAR data acquired by the Sentinel-1 constellation and designed to provide information on Earth surface displacements. In particular, the planned services will provide both advanced DInSAR products (deformation maps, velocity maps, deformation time series) and value-added measurements (source model

    The U.S. Geological Survey (USGS) produced its first topographic map in 1879, the same year it was established. Today, more than 100 years and millions of map copies later, topographic mapping is still a central activity for the USGS. The topographic map remains an indispensable tool for government, science, industry, and leisure. Much has changed since early topographers traveled the unsettled West and carefully plotted the first USGS maps by hand. Advances in survey techniques, instrumentation, and design and printing technologies, as well as the use of aerial photography and satellite data, have dramatically improved mapping coverage, accuracy, and efficiency. Yet cartography, the art and science of mapping, may never before have undergone change more profound than today.

    With the globalization and rapid development every filed is taking an increasing interest in physical geography and human economics. There is a surging demand for small scale world map in large formats all over the world. Further study of automated mapping technology, especially the realization of small scale production on a large scale global map, is the key of the cartographic field need to solve. In light of this, this paper adopts the improved model (with the map and data separated) in the field of the mapmaking generalization, which can separate geographic data from mapping data from maps, mainly including cross-platform symbols and automatic map-making knowledge engine. With respect to the cross-platform symbol library, the symbol and the physical symbol in the geographic information are configured at all scale levels. With respect to automatic map-making knowledge engine consists 97 types, 1086 subtypes, 21845 basic algorithm and over 2500 relevant functional modules.In order to evaluate the accuracy and visual effect of our model towards topographic maps and thematic maps, we take the world map generalization in small scale as an example. After mapping generalization process, combining and simplifying the scattered islands make the map more explicit at 1 : 2.1 billion scale, and the map features more complete and accurate. Not only it enhance the map generalization of various scales significantly, but achieve the integration among map-makings of various scales, suggesting that this model provide a reference in cartographic generalization for various scales.

    Maternity waiting homes (MWHs) are accommodations located near a health facility where women can stay towards the end of pregnancy and/or after birth to enable timely access to essential childbirth care or care for complications. Although MWHs have been implemented for over four decades, different operational models exist. This secondary thematic +analysis explores factors related to their implementation. A qualitative thematic analysis was conducted using 29 studies across 17 countries. The papers were identified through an existing Cochrane review and a mapping of the maternal health literature. The Supporting the Use of Research Evidence framework (SURE) guided the thematic analysis to explore the perceptions of various stakeholders and barriers and facilitators for implementation. The influence of contextual factors, the design of the MWHs, and the conditions under which they operated were examined. Key problems of MWH implementation included challenges in MWH maintenance and utilization by pregnant women. Poor utilization was due to lack of knowledge and acceptance of the MWH among women and communities, long distances to reach the MWH, and culturally inappropriate care. Poor MWH structures were identified by almost all studies as a major barrier, and included poor toilets and kitchens, and a lack of space for family and companions. Facilitators included reduced or removal of costs associated with using a MWH, community involvement in the design and upkeep of the MWHs, activities to raise awareness and acceptance among family and community members, and integrating culturally-appropriate practices into the provision of maternal and newborn care at the MWHs and the health facilities to which they are linked. MWHs should not be designed as an isolated intervention but using a health systems perspective, taking account of women and community perspectives, the quality of the MWH structure and the care provided at the health facility. Careful tailoring of the MWH to

  19. GRANULOMETRIC MAPS FROM HIGH RESOLUTION SATELLITE IMAGES

    Catherine Mering

    2011-05-01

    Full Text Available A new method of land cover mapping from satellite images using granulometric analysis is presented here. Discontinuous landscapes such as steppian bushes of semi arid regions and recently growing urban settlements are especially concerned by this study. Spatial organisations of the land cover are quantified by means of the size distribution analysis of the land cover units extracted from high resolution remotely sensed images. A granulometric map is built by automatic classification of every pixel of the image according to the granulometric density inside a sliding neighbourhood. Granulometric mapping brings some advantages over traditional thematic mapping by remote sensing by focusing on fine spatial events and small changes in one peculiar category of the landscape.

  20. New Map Symbol System for Disaster Management

    Marinova, Silvia T.

    2018-05-01

    In the last 10 years Bulgaria was frequently affected by natural and man-made disasters that caused considerable losses. According to the Bulgarian Disaster Management Act (2006) disaster management should be planned at local, regional and national level. Disaster protection is based on plans that include maps such as hazard maps, maps for protection, maps for evacuation planning, etc. Decision-making and cooperation between two or more neighboring municipalities or regions in crisis situation are still rendered difficult because the maps included in the plans differ in scale, colors, map symbols and cartographic design. To improve decision-making process in case of emergency and to reduce the number of human loss and property damages disaster management plans at local and regional level should be supported by detailed thematic maps created in accordance with uniform contents, map symbol system and design. The paper proposes a new symbol system for disaster management that includes a four level hierarchical classification of objects and phenomena according to their type and origin. All objects and phenomena of this classification are divided into five categories: disasters; infrastructure; protection services and infrastructure for protection; affected people and affected infrastructure; operational sites and activities. The symbols of these categories are shown with different background colors and shapes so that they are identifiable. All the symbols have simple but associative design. The new symbol system is used in the design of a series of maps for disaster management at local and regional level.

  1. Thematic and athematic present endings in Balto-Slavic and Indo-European

    Directory of Open Access Journals (Sweden)

    Frederik Kortlandt

    2015-09-01

    Full Text Available While the original primary thematic endings were preserved quite well in Balto-Slavic, they were often replaced by the corresponding athematic endings following the thematic vowel *‑e/o‑ in the other Indo-European languages, thus bringing them into line with the secondary endings. Without taking the semantics of the thematic flexion into consideration, Warren Cowgill has forcefully defended the traditional view that apart from the 1st sg. ending *‑ō, the thematic endings were identical with the athematic endings preceded by the thematic vowel *‑e/o‑ in Proto-Indo-European. The main point to be taken into consideration is that the rich and heterogeneous material of Balto-Slavic allows a reconstruction which is on the same level as that of Indo-Iranian and Greek. It confirms the view that our reconstructions have a bias toward the languages on which they are primarily based (Cowgill’s “trusty trio Hittite, Sanskrit, Greek”. The history of linguistic reconstruction shows a gradual shift away from the principal languages.

    Full Text Available The data-based research on which this article is based aimed at (1 describing the thematic progression variation of The Great Gatsby texts, (2 describing the contextual factors that motivate the variation in question, and (3 describing the effects of the variation on the texts as translational texts. The study applied a qualitative approach which employed a sematic-translational content analysis of qualitative and quantiative data. The results show that thematic progression variation falls into the low category at average indicated by the mean score of 0.76. The most prominent variation was repre-sented by the low category of variation. The variations were performed by adding or omitting Themes, splitting one units of thematic structure into more than one unit, downranking, not expressing and creating new clauses. The factors that motivate the variation are the different linguistic properties bet-ween English and Bahasa Indonesia and the situational contexts. In terms of effects, the variation caused dangling clauses which cannot be identified from which they are developed. Keywords: thematic progression, thematic structure, Theme, Rheme

    Since more than 20 years, "Earth Observation" (EO) satellites developed or operated by ESA have provided a wealth of data. In the coming years, the Sentinel missions, along with the Copernicus Contributing Missions as well as Earth Explorers and other, Third Party missions will provide routine monitoring of our environment at the global scale, thereby delivering an unprecedented amount of data. While the availability of the growing volume of environmental data from space represents a unique opportunity for science, general R&D, and applications, it also poses major challenges to fully exploit the potential of archived and daily incoming datasets. Those challenges do not only comprise the discovery, access, processing, and visualization of large data volumes but also an increasing diversity of data sources and end users from different fields (e.g. EO, in-situ monitoring, and modeling). In this context, the GTEP (Geohazards Thematic Exploitation Platform) initiative aims to build an operational distributed processing platform to maximize the exploitation of EO data from past and future satellite missions for the detection and monitoring of natural hazards. This presentation focuses on the "Optical Image Correlation" Pilot Project (funded by ESA within the GTEP platform) which objectives are to develop an easy-to-use, flexible and distributed processing chain for: 1) the automated reconstruction of surface Digital Elevation Models from stereo (and tristereo) pairs of Spot 6/7 and Pléiades satellite imagery, 2) the creation of ortho-images (panchromatic and multi-spectral) of Landsat 8, Sentinel-2, Spot 6/7 and Pléiades scenes, 3) the calculation of horizontal (E-N) displacement vectors based on sub-pixel image correlation. The processing chains is being implemented on the GEP cloud-based (Hadoop, MapReduce) environment and designed for analysis of surface displacements at local to regional scale (10-1000 km2) targeting in particular co-seismic displacement and slow

    The generativity and complexity of human thought stem in large part from the ability to represent relations among concepts and form propositions. The current study reveals how a given object such as rabbit is neurally encoded differently and identifiably depending on whether it is an agent ("the rabbit punches the monkey") or a patient ("the monkey punches the rabbit"). Machine-learning classifiers were trained on functional magnetic resonance imaging (fMRI) data evoked by a set of short videos that conveyed agent-verb-patient propositions. When tested on a held-out video, the classifiers were able to reliably identify the thematic role of an object from its associated fMRI activation pattern. Moreover, when trained on one subset of the study participants, classifiers reliably identified the thematic roles in the data of a left-out participant (mean accuracy = .66), indicating that the neural representations of thematic roles were common across individuals.

    Abstract Objectives. To examine the accounts of people with body dysmorphic disorder (BDD) and qualitatively explore self perceptions. Methods. Eleven people with BDD were interviewed using a semi-structured schedule. Participants brought photographs of themselves and drew a self-portrait. Transcribed interviews were analysed using a thematic analysis. Results. The most common theme was increased threat perception resulting in disordered interpersonal relationships. Other themes included the wish for regularity and symmetry in appearance, an idealised childhood self, the duty to look good, and a focus on specific "defective" features rather than general ugliness. Conclusions. Using thematic analysis and visual methods, we identified core themes that appear to characterise the way individuals with BDD perceive themselves and their interpersonal relationships. Thematic analysis offers promise as a tool to explore the overlap between BDD and other putatively related mental health problems.

    The majority of research on understanding the illness focuses on analysing the written or verbal content. Thematic analysis of images is a novel qualitative approach that can enhance knowledge of the experience of illness. This study used thematic analysis to examine 171 tiles painted by patients through the Tiles of Hope programme in an outpatient blood and marrow transplant unit. Major themes identified in this study were Faith, Hope, Positive Attitude, Nature and Social Support. These themes provided a better understanding of patients' perceptions in relation to their experience with illness through the art-making process. © 2015 John Wiley & Sons Ltd.

    1983-01-01

    A cooperative research project was initiated in 1982 to study differences in thematic mapper spectral characteristics caused by variable tillage and crop residue practices. Initial evaluations of radiometric data suggest that spectral separability of variably tilled soils can be confounded by moisture and weathering effects. Separability of bare tilled soils from those with significant amounts of corn residue is enhanced by wet conditions, but still possible under dry conditions when recent tillage operations have occurred. In addition, thematic mapper data may provide an alternative method to study the radiant energy balance at the soil surface in conjunction with variable tillage systems.

  10. Land Cover Mapping in Northern High Latitude Permafrost Regions with Satellite Data: Achievements and Remaining Challenges

    Directory of Open Access Journals (Sweden)

    Annett Bartsch

    2016-11-01

    Full Text Available Most applications of land cover maps that have been derived from satellite data over the Arctic require higher thematic detail than available in current global maps. A range of application studies has been reviewed, including up-scaling of carbon fluxes and pools, permafrost feature mapping and transition monitoring. Early land cover mapping studies were driven by the demand to characterize wildlife habitats. Later, in the 1990s, up-scaling of in situ measurements became central to the discipline of land cover mapping on local to regional scales at several sites across the Arctic. This includes the Kuparuk basin in Alaska, the Usa basin and the Lena Delta in Russia. All of these multi-purpose land cover maps have been derived from Landsat data. High resolution maps (from optical satellite data serve frequently as input for the characterization of periglacial features and also flux tower footprints in recent studies. The most used map to address circumpolar issues is the CAVM (Circum Arctic Vegetation Map based on AVHRR (1 km and has been manually derived. It provides the required thematic detail for many applications, but is confined to areas north of the treeline, and it is limited in spatial detail. A higher spatial resolution circumpolar land cover map with sufficient thematic content would be beneficial for a range of applications. Such a land cover classification should be compatible with existing global maps and applicable for multiple purposes. The thematic content of existing global maps has been assessed by comparison to the CAVM and regional maps. None of the maps provides the required thematic detail. Spatial resolution has been compared to used classes for local to regional applications. The required thematic detail increases with spatial resolution since coarser datasets are usually applied over larger areas covering more relevant landscape units. This is especially of concern when the entire Arctic is addressed. A spatial

    Moss, Donald B

    2006-01-01

    The author uses the metaphor of mapping to illuminate a structural feature of racist thought, locating the degraded object along vertical and horizontal axes. These axes establish coordinates of hierarchy and of distance. With the coordinates in place, racist thought begins to seem grounded in natural processes. The other's identity becomes consolidated, and parochialism results. The use of this kind of mapping is illustrated via two patient vignettes. The author presents Freud's (1905, 1927) views in relation to such a "mapping" process, as well as Adorno's (1951) and Baldwin's (1965). Finally, the author conceptualizes the crucial status of primitivity in the workings of racist thought.

    Professionalism development is influenced by the informal and hidden curriculum. The primary objective of this study was to better understand this experiential learning in the setting of the Emergency Department (ED). Secondarily, the study aimed to explore differences in the informal curriculum between Emergency Medicine (EM) and Internal Medicine (IM) clerkships. A thematic analysis was conducted on 377 professionalism narratives from medical students completing a required EM clerkship from July 2008 through May 2010. The narratives were analyzed using established thematic categories from prior research as well as basic descriptive characteristics. Chi-square analysis was used to compare the frequency of thematic categories to prior research in IM. Finally, emerging themes not fully appreciated in the established thematic categories were created using grounded theory. Observations involving interactions between attending physician and patient were most abundant. The narratives were coded as positive 198 times, negative 128 times, and hybrid 37 times. The two most abundant narrative themes involved manifesting respect (36.9%) and spending time (23.7%). Both of these themes were statistically more likely to be noted by students on EM clerkships compared to IM clerkships. Finally, one new theme regarding cynicism emerged during analysis.

  17. What does 'recovery' mean to people with neck pain? Results of a descriptive thematic analysis.

    Science.gov (United States)

    Walton, David M; Macdermid, Joy C; Taylor, Todd

    2013-01-01

    To describe the meaning of being recovered as perceived by people with chronic mechanical neck pain. To determine the way people with neck pain would describe a recovered state a descriptive thematic approach was used. A nominal focus group technique, written reflections, and one-on-one semi-structured interviews were used to collect sufficient data. Data from the focus groups were analyzed both through vote tallying and thematic analysis. Reflections and interviews were analyzed thematically by two independent researchers. Triangulation and member-checking were employed to establish trustworthiness of results. A total of 35 people, primarily females with neck pain of traumatic origin, participated in this study. Thematic analysis identified 6 themes that adequately described the data: absent or manageable symptoms, having the physical capacity one ought to have, participation in life roles, feeling positive emotions, autonomy & spontaneity, and re-establishing a sense of self. Member checking and triangulation suggested data saturation and accuracy of the generated themes. Recovery from neck pain appears to be informed by factors that fit with existing models of health, quality of life and satisfaction. Basing recovery solely on symptom or activity-level measures risks inaccurate estimates of recovery trajectories from traumatic or non-traumatic neck pain.

    2014-01-01

    Full Text Available Enhancing visitor experiences is arguably the primary and most important goal for interpretation by many protected area managers and tourism business. However, little research has been conducted in Sarawak, Malaysia to directly quantify the effects of thematic interpretation has on tourist experiences. Drawing on the TORE-model of interpretation and through the inception of Park Guiding Training and Licensing System in Sarawak since 2007, this quantitative study examines the effectiveness of thematic interpretive guided tours delivered by park guides at Bako National Park, Sarawak, with the assumption that it will further enhance visitor experiences. A descriptive analysis and Pearson's product-moment correlation analysis of sub-indicators of the global evaluation of interpretation of site, and sub-indicators of elaboration surveyed from visitors of purposively sampled park guides revealed a strong measurement and correlation coefficients of visitors’ overall quality of thematic intepretive guided tours effecting visitor satisfaction and experiences. These findings provide empirical evidence that good thematic interpretive guided tour makes a positive impacts on visitor experiences, thus making training of tourism businesses' employees as park guides as a good investment. The suggestions for further research in influencing visitor attitude and shaping visitor behaviour are offered.

  8. Thematic orders and the comprehension of subject-extracted relative clauses in Mandarin Chinese

    Directory of Open Access Journals (Sweden)

    Chien-Jer Charles Lin

    2015-09-01

    Full Text Available This study investigates the comprehension of three kinds of subject-extracted relative clauses (SRs in Mandarin Chinese: standard SRs, relative clauses involving the disposal ba construction (‘disposal SRs’, and relative clauses involving the long passive bei constructions (‘passive SRs’. In a self-paced reading experiment, the regions before the relativizer (where the sentential fragments are temporarily ambiguous showed reading patterns consistent with expectation-based incremental processing: standard SRs (with the highest constructional frequency and the least complex syntactic structure were processed faster than the other two variants. However, in the regions after the relativizer and the head noun (where the existence of a relative clause is unambiguously indicated, a top-down global effect of thematic ordering was observed: passive SRs (whose thematic role order conforms to the canonical thematic order of Chinese were read faster than both the standard SRs and the disposal SRs. Taken together, these results suggest that two expectation-based processing factors are involved in the comprehension of Chinese relative clauses, including both the structural probabilities of pre-relativizer constituents and the overall surface thematic orders in the relative clauses.

  16. Methods for the thematic synthesis of qualitative research in systematic reviews

    Directory of Open Access Journals (Sweden)

    Harden Angela

    2008-07-01

    Full Text Available Abstract Background There is a growing recognition of the value of synthesising qualitative research in the evidence base in order to facilitate effective and appropriate health care. In response to this, methods for undertaking these syntheses are currently being developed. Thematic analysis is a method that is often used to analyse data in primary qualitative research. This paper reports on the use of this type of analysis in systematic reviews to bring together and integrate the findings of multiple qualitative studies. Methods We describe thematic synthesis, outline several steps for its conduct and illustrate the process and outcome of this approach using a completed review of health promotion research. Thematic synthesis has three stages: the coding of text 'line-by-line'; the development of 'descriptive themes'; and the generation of 'analytical themes'. While the development of descriptive themes remains 'close' to the primary studies, the analytical themes represent a stage of interpretation whereby the reviewers 'go beyond' the primary studies and generate new interpretive constructs, explanations or hypotheses. The use of computer software can facilitate this method of synthesis; detailed guidance is given on how this can be achieved. Results We used thematic synthesis to combine the studies of children's views and identified key themes to explore in the intervention studies. Most interventions were based in school and often combined learning about health benefits with 'hands-on' experience. The studies of children's views suggested that fruit and vegetables should be treated in different ways, and that messages should not focus on health warnings. Interventions that were in line with these suggestions tended to be more effective. Thematic synthesis enabled us to stay 'close' to the results of the primary studies, synthesising them in a transparent way, and facilitating the explicit production of new concepts and hypotheses

    Zahid Ali Veesar

    2015-07-01

    Full Text Available This study focuses on the thematic structure of the Sindhi verbs to find theta roles in the Sindhi language. The study tries to answer the research questions; “What are the thematic structures of Sindhi verbs?” and “What are the prominent theta roles in the Sindhi language?” It examines the argument/thematic structure of Sindhi verbs and also finds the theta roles assigned by the Sindhi verbs to their arguments along with the most prominent theta roles used in the Sindhi language. The data come from the two interviews taken from two young native Sindhi speakers, which consist of 2 hours conversation having 1,669 sentences in natural spoken version of the Sindhi language. Towards the end, it has been found that the Sindhi language has certain theta roles which are assigned by the verbs to their arguments in sentences. Each verb phrase in our data is thus examined and studied in detail in terms of Argument/Thematic structure in order to find theta roles in Sindhi language. Thus, in this regard, each verb phrase (in a sentence has been examined with the help of Carnie’s theoretical framework (Thematic Relation and Theta Roles: 2006 in order to find the prominent theta roles in the Sindhi language. The data have been examined and analysed on the basis of the Carnie’s theoretical framework. The study finds that the Sindhi language has all (09 theta roles which have been proposed by Carnie (2006. It has been found that six prominent theta roles out of nine are used prominently in Sindhi. The six prominent theta roles in Sindhi language are: agent, theme, beneficiary, recipient, locative and goal.

    Spatial data characteristics have the potential to influence various aspects of prioritising biodiversity areas for systematic conservation planning. There has been some exploration of the combined effects of size of planning units and level of classification of physical environments on the pattern and extent of priority areas. However, these data characteristics have yet to be explicitly investigated in terms of their interaction with different socioeconomic cost data during the spatial prioritisation process. We quantify the individual and interacting effects of three factors-planning-unit size, thematic resolution of reef classes, and spatial variability of socioeconomic costs-on spatial priorities for marine conservation, in typical marine planning exercises that use reef classification maps as a proxy for biodiversity. We assess these factors by creating 20 unique prioritisation scenarios involving combinations of different levels of each factor. Because output data from these scenarios are analogous to ecological data, we applied ecological statistics to determine spatial similarities between reserve designs. All three factors influenced prioritisations to different extents, with cost variability having the largest influence, followed by planning-unit size and thematic resolution of reef classes. The effect of thematic resolution on spatial design depended on the variability of cost data used. In terms of incidental representation of conservation objectives derived from finer-resolution data, scenarios prioritised with uniform cost outperformed those prioritised with variable cost. Following our analyses, we make recommendations to help maximise the spatial and cost efficiency and potential effectiveness of future marine conservation plans in similar planning scenarios. We recommend that planners: employ the smallest planning-unit size practical; invest in data at the highest possible resolution; and, when planning across regional extents with the intention

  1. Examination of China’s performance and thematic evolution in quantum cryptography research using quantitative and computational techniques

    Science.gov (United States)

    2018-01-01

    This study performed two phases of analysis to shed light on the performance and thematic evolution of China’s quantum cryptography (QC) research. First, large-scale research publication metadata derived from QC research published from 2001–2017 was used to examine the research performance of China relative to that of global peers using established quantitative and qualitative measures. Second, this study identified the thematic evolution of China’s QC research using co-word cluster network analysis, a computational science mapping technique. The results from the first phase indicate that over the past 17 years, China’s performance has evolved dramatically, placing it in a leading position. Among the most significant findings is the exponential rate at which all of China’s performance indicators (i.e., Publication Frequency, citation score, H-index) are growing. China’s H-index (a normalized indicator) has surpassed all other countries’ over the last several years. The second phase of analysis shows how China’s main research focus has shifted among several QC themes, including quantum-key-distribution, photon-optical communication, network protocols, and quantum entanglement with an emphasis on applied research. Several themes were observed across time periods (e.g., photons, quantum-key-distribution, secret-messages, quantum-optics, quantum-signatures); some themes disappeared over time (e.g., computer-networks, attack-strategies, bell-state, polarization-state), while others emerged more recently (e.g., quantum-entanglement, decoy-state, unitary-operation). Findings from the first phase of analysis provide empirical evidence that China has emerged as the global driving force in QC. Considering China is the premier driving force in global QC research, findings from the second phase of analysis provide an understanding of China’s QC research themes, which can provide clarity into how QC technologies might take shape.

    Copernicus, previously known as GMES (Global Monitoring for Environment and Security), is the European Programme for the establishment of a European capacity for Earth Observation and Monitoring. Copernicus aims to provide a sustainable service for Ocean Monitoring and Forecasting validated and commissioned by users. From May 2015, the Copernicus Marine Environment Monitoring Service (CMEMS) is working on an operational mode through a contract with services engagement (result is regular data provision). Within CMEMS, the In Situ Thematic Assembly Centre (INSTAC) distributed service integrates in situ data from different sources for operational oceanography needs. CMEMS INSTAC is collecting and carrying out quality control in a homogeneous manner on data from providers outside Copernicus (national and international networks), to fit the needs of internal and external users. CMEMS INSTAC has been organized in 7 regional Dissemination Units (DUs) to rely on the EuroGOOS ROOSes. Each DU aggregates data and metadata provided by a series of Production Units (PUs) acting as an interface for providers. Homogeneity and standardization are key features to ensure coherent and efficient service. All DUs provide data in the OceanSITES NetCDF format 1.2 (based on NetCDF 3.6), which is CF compliant, relies on SeaDataNet vocabularies and is able to handle profile and time-series measurements. All the products, both near real-time (NRT) and multi-year (REP), are available online for every CMEMS registered user through an FTP service. On top of the FTP service, INSTAC products are available through Oceanotron, an open-source data server dedicated to marine observations dissemination. It provides services such as aggregation on spatio-temporal coordinates and observed parameters, and subsetting on observed parameters and metadata. The accuracy of the data is checked on various levels. Quality control procedures are applied for the validity of the data and correctness tests for the

    This study examined thematic differences in the multicultural case conceptualization content of 61 psychotherapy trainees across three different cases and trainee demographics (number of multicultural courses completed, years of supervised clinical practicum completed, and White trainee vs. trainee of color). Themes across cases included general counseling skills (attend to affect, build rapport, focus on specific client concerns, use of specific clinical interventions, and use of external resources not related to culture), as well as multicultural specific counseling skills (focus on culture, focus on discrimination, use of culturally competent interventions, and use of external resources related to culture). Thematic differences across case were found in three of the nine themes (affect, culture, discrimination). No systematic differences were found across multicultural training, clinical training, or race. Implications of these results are discussed.

    The results of the analysis of aircraft-acquired thematic mapper simulator (TMS) data, collected to investigate the utility of thematic mapper data in crop area and land cover estimates, are discussed. Results of the analysis indicate that the seven-channel TMS data are capable of delineating the 13 crop types included in the study to an overall pixel classification accuracy of 80.97% correct, with relative efficiencies for four crop types examined between 1.62 and 26.61. Both supervised and unsupervised spectral signature development techniques were evaluated. The unsupervised methods proved to be inferior (based on analysis of variance) for the majority of crop types considered. Given the ground truth data set used for spectral signature development as well as evaluation of performance, it is possible to demonstrate which signature development technique would produce the highest percent correct classification for each crop type.

    Full Text Available Word pairs may be integrative (i.e., combination of two concepts into one meaningful entity; e.g., fruit - cake, thematically related (i.e., connected in time and place; e.g., party - cake, and/or taxonomically related (i.e., shared features and category co-members; e.g., muffin - cake. Using participant ratings and computational measures, we demonstrated distinct patterns across measures of similarity and co-occurrence, and familiarity for each relational construct in two different item sets. Overall, target RTs and priming magnitudes were consistent across the SOAs for both item sets. However, results of a standard lexical decision task with various delays between prime and target presentation further demonstrated distinct patterns among these three relations on some of the underlying measures influencing target word recognition (LSA, Google, and BEAGLE. These distinct patterns suggest different mechanisms of lexical priming and further demonstrate that integrative relations are distinct from thematic and taxonomic relations.

    Environmental assessments of oil field activities, historical and present, were made using a combination of Landsat Thematic Mapper, aerial photographic and GIS information. Landsat data was used to assess vegetation health in and around the oil fields, and aerial photography was used to document historic changes. We found no evidence of vegetation damage from the oil field activities, even though many fields are located along anticlines and drain into major waterways. GIS technology, mapping roads, wells, rivers, ponds and environmentally-sensitive areas, was used to minimize environmental effects on the placement of shotpoints and receivers. When either shotpoints or receivers were found to interfere with sensitive areas, the points were moved to nearby roads or other open locations. The application of this technology resulted in minimal environmental damage and significant cost savings

    Thematic Mapper data were analyzed with respect to its capability for mapping the complex structure and dynamics of suspended matter distribution in the coastal area of the German Bight (North Sea). Three independent pieces of information were found by factor analysis of all seven TM channels: suspended matter concentration, atmospheric scattering, and sea surface temperature. For the required atmospheric correction, the signal-to-noise ratios of Channels 5 and 7 have to be improved by averaging over 25 x 25 pixels, which also makes it possible to monitor the aerosol optical depth and aerosol type over cloud-free water surfaces. Near-surface suspended matter concentrations may be detected with an accuracy of factor less than 2 by using an algorithm derived from radiative transfer model calculation. The patchiness of suspended matter and its relation to underwater topography was analyzed with autocorrelation and cross-correlation.

    Đurašević Silvana

    2014-01-01

    Full Text Available The aim of this paper is to point out to a growing trend of interests of modern tourists for various forms of thematic tourism, as a response to the tendency of uniformity of consumers' lifestyle, which globalization has brought. Thanks to their central place in the tourism system and their expertise, tour operators play a key role in the creation of new programs, 'tailored' to the taste of modern tourists. For that purpose, a number of theoretical assumptions and examples from practice have been analyzed and the method of understanding cause-and-effect relationships is used, in order to examine the role of tour operators in application of new thematic programs. The need to emphasize the special customers' requirements regarding travel services creates an additional problem to tour operators. It indicates the trend of individual trips, which requires a change in choice of markets and product differentiation. The research findings suggest the conclusion that tour operators need to adapt their business strategies to new market conditions, using advantages of information technology in designing diverse thematic programs, which will enable tourists to perceive other local values and express their individuality looking for authentic experiences.

  1. The influence of thematic congruency, typicality and divided attention on memory for radio advertisements.

    Martín-Luengo, Beatriz; Luna, Karlos; Migueles, Malen

    2014-01-01

    We examined the effects of the thematic congruence between ads and the programme in which they are embedded. We also studied the typicality of the to-be-remembered information (high- and low-typicality elements), and the effect of divided attention in the memory for radio ad contents. Participants listened to four radio programmes with thematically congruent and incongruent ads embedded, and completed a true/false recognition test indicating the level of confidence in their answer. Half of the sample performed an additional task (divided attention group) while listening to the radio excerpts. In general, recognition memory was better for incongruent ads and low-typicality statements. Confidence in hits was higher in the undivided attention group, although there were no differences in performance. Our results suggest that the widespread idea of embedding ads into thematic-congruent programmes negatively affects memory for ads. In addition, low-typicality features that are usually highlighted by advertisers were better remembered than typical contents. Finally, metamemory evaluations were influenced by the inference that memory should be worse if we do several things at the same time.

    2013-09-01

    Qualitative content analysis and thematic analysis are two commonly used approaches in data analysis of nursing research, but boundaries between the two have not been clearly specified. In other words, they are being used interchangeably and it seems difficult for the researcher to choose between them. In this respect, this paper describes and discusses the boundaries between qualitative content analysis and thematic analysis and presents implications to improve the consistency between the purpose of related studies and the method of data analyses. This is a discussion paper, comprising an analytical overview and discussion of the definitions, aims, philosophical background, data gathering, and analysis of content analysis and thematic analysis, and addressing their methodological subtleties. It is concluded that in spite of many similarities between the approaches, including cutting across data and searching for patterns and themes, their main difference lies in the opportunity for quantification of data. It means that measuring the frequency of different categories and themes is possible in content analysis with caution as a proxy for significance. © 2013 Wiley Publishing Asia Pty Ltd.

  3. Toward combining thematic information with hierarchical multiscale segmentations using tree Markov random field model

    Science.gov (United States)

    Zhang, Xueliang; Xiao, Pengfeng; Feng, Xuezhi

    2017-09-01

    It has been a common idea to produce multiscale segmentations to represent the various geographic objects in high-spatial resolution remote sensing (HR) images. However, it remains a great challenge to automatically select the proper segmentation scale(s) just according to the image information. In this study, we propose a novel way of information fusion at object level by combining hierarchical multiscale segmentations with existed thematic information produced by classification or recognition. The tree Markov random field (T-MRF) model is designed for the multiscale combination framework, through which the object type is determined as close as the existed thematic information. At the same time, the object boundary is jointly determined by the thematic labels and the multiscale segments through the minimization of the energy function. The benefits of the proposed T-MRF combination model include: (1) reducing the dependence of segmentation scale selection when utilizing multiscale segmentations; (2) exploring the hierarchical context naturally imbedded in the multiscale segmentations. The HR images in both urban and rural areas are used in the experiments to show the effectiveness of the proposed combination framework on these two aspects.

    Full Text Available A major challenge for tourism in the modern world is an increasing need for new tourist attractions and products in destinations. The tourism industry adapts to the demands of modern tourism market, introducing innovations to existing destinations and activities. In order to improve the presentation of tourism and cultural heritage of consumption goods, it is necessary to encourage the development of cultural tourist routes that would be applicable in tourism practices. In this case, it refers to the ability to create thematic cultural routes that would have a focus on specific historical and cultural values in the Petrovaradin fortress. The aim of this study, based on the opinions of experts and local people - visitors about the values and potential of the Fortress, was to identify key values, and the possibility that the cultural and historical values are the basis for the creation of thematic cultural routes. The result is obtained via method of interviewing people - visitors, as well as through interviews with three different groups of respondents. This paper presents the views of respondents about the potential of the Fortress and its core values, based on which potential cultural thematic routes are suggested, as well as the results of direct study of the possibilities of creating them. In addition to the field and bibliographic research, the method of content analysis was also applied.

    The Commission has presented a thematic strategy on air pollution and has completed an Impact Assessment, which describes the costs and benefits for the member states. The thematic strategy is to result in a revised air quality directive as well as a revised NEC-directive that determines maximum emissions for a number of air pollution components, the so-called emission ceilings. The air pollution components include sulphur dioxide (SO 2 ), nitrogen oxide (NO X ), volatile organic compounds (NMVOC), ammonia (NH 3 ) and particulate matters (PM 2,5 ). The thematic strategy draws up targets for reductions of the Danish emissions for these components, which have to be met by 2020. These reductions will contribute to a lowering of PM 2,5 concentrations both in Denmark and in neighbouring countries. The concentration of PM 2,5 in the air includes both primary particles that come from emission of particles from e.g. incineration processes, and so-called secondary particles that are generated from emissions of NO X , SO 2 and NH 3 , and from releases from e.g. vegetation. A very large part of the secondary particles in the air in Denmark stems from emissions of these components in the rest of Europe. A very important condition for a reduction in the concentration of PM 2,5 in the air is thus a reduction of the emissions of these components in all of Europe. (au)

  8. Error and Uncertainty in the Accuracy Assessment of Land Cover Maps

    Science.gov (United States)

    Sarmento, Pedro Alexandre Reis

    Traditionally the accuracy assessment of land cover maps is performed through the comparison of these maps with a reference database, which is intended to represent the "real" land cover, being this comparison reported with the thematic accuracy measures through confusion matrixes. Although, these reference databases are also a representation of reality, containing errors due to the human uncertainty in the assignment of the land cover class that best characterizes a certain area, causing bias in the thematic accuracy measures that are reported to the end users of these maps. The main goal of this dissertation is to develop a methodology that allows the integration of human uncertainty present in reference databases in the accuracy assessment of land cover maps, and analyse the impacts that uncertainty may have in the thematic accuracy measures reported to the end users of land cover maps. The utility of the inclusion of human uncertainty in the accuracy assessment of land cover maps is investigated. Specifically we studied the utility of fuzzy sets theory, more precisely of fuzzy arithmetic, for a better understanding of human uncertainty associated to the elaboration of reference databases, and their impacts in the thematic accuracy measures that are derived from confusion matrixes. For this purpose linguistic values transformed in fuzzy intervals that address the uncertainty in the elaboration of reference databases were used to compute fuzzy confusion matrixes. The proposed methodology is illustrated using a case study in which the accuracy assessment of a land cover map for Continental Portugal derived from Medium Resolution Imaging Spectrometer (MERIS) is made. The obtained results demonstrate that the inclusion of human uncertainty in reference databases provides much more information about the quality of land cover maps, when compared with the traditional approach of accuracy assessment of land cover maps.

    Most current models of knowledge organization are based on hierarchical or taxonomic categories (animals, tools). Another important organizational pattern is thematic categorization, i.e. categories held together by external relations, a unifying scene or event (car and garage). The goal of this study was to compare the neural correlates of these categories under automatic processing conditions that minimize strategic influences. We used fMRI to examine neural correlates of semantic priming for category members with a short stimulus onset asynchrony (SOA) of 200 ms as subjects performed a lexical decision task. Four experimental conditions were compared: thematically related words (car-garage); taxonomically related (car-bus); unrelated (car-spoon); non-word trials (car-derf). We found faster reaction times for related than for unrelated prime-target pairs for both thematic and taxonomic categories. However, the size of the thematic priming effect was greater than that of the taxonomic. The imaging data showed signal changes for the taxonomic priming effects in the right precuneus, postcentral gyrus, middle frontal and superior frontal gyri and thematic priming effects in the right middle frontal gyrus and anterior cingulate. The contrast of neural priming effects showed larger signal changes in the right precuneus associated with the taxonomic but not with thematic priming response. We suggest that the greater involvement of precuneus in the processing of taxonomic relations indicates their reduced salience in the knowledge structure compared to more prominent thematic relations.

  10. IMPLEMENTATION OF OPEN-SOURCE WEB MAPPING TECHNOLOGIES TO SUPPORT MONITORING OF GOVERNMENTAL SCHEMES

    2015-10-01

    Full Text Available Several schemes are undertaken by the government to uplift social and economic condition of people. The monitoring of these schemes is done through information technology where involvement of Geographic Information System (GIS is lacking. To demonstrate the benefits of thematic mapping as a tool for assisting the officials in making decisions, a web mapping application for three government programs such as Mother and Child Tracking system (MCTS, Telangana State Housing Corporation Limited (TSHCL and Ground Water Quality Mapping (GWQM has been built. Indeed the three applications depicted the distribution of various parameters thematically and helped in identifying the areas with higher and weaker distributions. Based on the three applications, the study tends to find similarities of many government schemes reflecting the nature of thematic mapping and hence deduces to implement this kind of approach for other schemes as well. These applications have been developed using SharpMap Csharp library which is a free and open source mapping library for developing geospatial applications. The study highlights upon the cost benefits of SharpMap and brings out the advantage of this library over proprietary vendors and further discusses its advantages over other open source libraries as well.

    Geologic maps present, in an historical context, fundamental syntheses of interpretations of the materials, landforms, structures, and processes that characterize planetary surfaces and shallow subsurfaces. Such maps also provide a contextual framework for summarizing and evaluating thematic research for a given region or body. In planetary exploration, for example, geologic maps are used for specialized investigations such as targeting regions of interest for data collection and for characterizing sites for landed missions. Whereas most modern terrestrial geologic maps are constructed from regional views provided by remote sensing data and supplemented in detail by field-based observations and measurements, planetary maps have been largely based on analyses of orbital photography. For planetary bodies in particular, geologic maps commonly represent a snapshot of a surface, because they are based on available information at a time when new data are still being acquired. Thus the field of planetary geologic mapping has been evolving rapidly to embrace the use of new data and modern technology and to accommodate the growing needs of planetary exploration. Planetary geologic maps have been published by the U.S. Geological Survey (USGS) since 1962. Over this time, numerous maps of several planetary bodies have been prepared at a variety of scales and projections using the best available image and topographic bases. Early geologic map bases commonly consisted of hand-mosaicked photographs or airbrushed shaded-relief views and geologic linework was manually drafted using mylar bases and ink drafting pens. Map publishing required a tedious process of scribing, color peel-coat preparation, typesetting, and photo-laboratory work. Beginning in the 1990s, inexpensive computing, display capability and user-friendly illustration software allowed maps to be drawn using digital tools rather than pen and ink, and mylar bases became obsolete.

  12. Paleobasin analysis and tectonic framework development of southern Zagros basin, interpreted from Landsat 4 thematic mapper image

    1986-05-01

    Detailed lineament maps produced with the digitally enhanced Landsat 4 thematic mapper in conjunction with field data provide new information on structural relations to the southern Zagros basin. Three major parallel lineaments are from north to south, Qatar-Kazern, Razak, and Oman. These lineaments trend approximately N17/sup 0/E and subdivide the Zagros basin into northern, central, and southern segments. The study area is enclosed by the Razak and Oman lineaments. Piercement salt domes (Precambrian salt) are abundant within the southern Zagros basin, absent east of the Oman lineament, and scarce in the area west of the Razak lineament. This salt dome distribution and the N17/sup 0/E trend suggest that these lineaments are surface manifestations of boundaries of basement crustal blocks that have been reactivated periodically since the Precambrian. The northern extension of this Precambrian basin is marked by salt domes (Precambrian salt) along the Oman lineament, located in the Kerman region 400 km north of Minab. Along the eastern boundary, at the juncture of the southern Zagros basin and western Makran Ranges, the trend of fold axes changes from east-west to north-south. The western basin boundary is characterized by a gradual change in the trend of the fold axis from east-west to northwest-southeast. This study provides useful information for subsurface interpretations, which will benefit hydrocarbon exploration. The Razak and Oman lineaments enclose a highly productive area, and separate the southern Zagros basin from less productive areas to the west and from a nonproductive region to the east where chromite and iron deposits are common. These findings suggest that lineaments may serve as an exploration guide for hydrocarbons and economic mineral deposits, and as a model for developing the tectonic framework of the southern Zagros basin.

    Non-medical prescribing has the potential to deliver innovative healthcare within limited finances. However, uptake has been slow, and a proportion of non-medical prescribers do not use the qualification. This systematic review aimed to describe the facilitators and barriers to non-medical prescribing in the United Kingdom. The systematic review and thematic analysis included qualitative and mixed methods papers reporting facilitators and barriers to independent non-medical prescribing in the United Kingdom. The following databases were searched to identify relevant papers: AMED, ASSIA, BNI, CINAHL, EMBASE, ERIC, MEDLINE, Open Grey, Open access theses and dissertations, and Web of Science. Papers published between 2006 and March 2017 were included. Studies were quality assessed using a validated tool (QATSDD), then underwent thematic analysis. The protocol was registered with PROSPERO (CRD42015019786). Of 3991 potentially relevant identified studies, 42 were eligible for inclusion. The studies were generally of moderate quality (83%), and most (71%) were published 2007-2012. The nursing profession dominated the studies (30/42). Thematic analysis identified three overarching themes: non-medical prescriber, human factors, and organisational aspects. Each theme consisted of several sub-themes; the four most highly mentioned were 'medical professionals', 'area of competence', 'impact on time' and 'service'. Sub-themes were frequently interdependent on each other, having the potential to act as a barrier or facilitator depending on circumstances. Addressing the identified themes and subthemes enables strategies to be developed to support and optimise non-medical prescribing. Further research is required to identify if similar themes are encountered by other non-medical prescribing groups than nurses and pharmacists.

    * [ ] Indicates prosodic contour Methods: Twenty-four healthy college-age control participants (YNCs and ten adults with a Broca’s aphasia participated in this study. Each sentence was presented aurally to the participants over headphones. ERP Data Recording & Analysis. ERPs were recorded from 32-electrode sites across the scalp according to the 10-20 system. ERPs were averaged (100ms prestimulus baseline from artifact free trials time-locked to critical words (i.e., the point of disambiguation “pleased” in the prosodic comparison, and the NP “the song”/”the beer” in the semantic comparison. Mean amplitudes were calculated in two windows: 300-500ms for the N400 effects and 500-1000ms for the P600 effects. Results: The data from our YNCs revealed a biphasic N400-P600 complex in the prosody comparison (Figure 1A. We also found an N400 effect immediately at the NP in the incongruent relative to congruent thematic fit comparison. For the prosodic comparison in the PWA group, a delayed N400 effect was found one word downstream relative to the YNC data in the prosody comparison (Figure 1B. Additionally, an N400 effect was observed in the thematic fit comparison. Discussion: The results suggests that PWA possess a delayed sensitivity to prosodic cues, which then may affect their ability to recover from misanalysis from an incorrect parse. The results also indicate that PWA are sensitive to thematic fit information and have the capacity to process this information similarly to YNCs.

    2017-12-01

    In line with the paradigm shift in Earth Observation of "Bringing the users to the data", ESA provides collaborative, virtual work environments giving access to EO data and tools, processors, and ICT resources through coherent interfaces. These coherent interfaces are categorized thematically, tailored to the related user communities and named Thematic Exploitation Platforms (TEP). The Food Security Thematic Exploitation Platform (FS-TEP) is the youngest out of seven TEPs and is developed in an agile mode in close coordination with its users. It will provide a "one stop platform" for the extraction of information from EO data for services in the food security sector mainly in Europe & Africa, allowing both access to EO data and processing of these data sets. Thereby it will foster smart, data-intensive agricultural and aquacultural applications in the scientific, private and public domain. The FS-TEP builds on a large and heterogeneous user community, spanning from application developers in agriculture to aquaculture, from small-scale farmers to agricultural industry, from public science to the finance and insurance sectors, from local and national administration to international agencies. To meet the requirements of these groups, the FS-TEP will provide different frontend interfaces.

    The purpose of this thematic synthesis review was to identify and synthesise published qualitative research on the perspectives of individuals with spinal cord injuries with respect to physical rehabilitation interventions. The peer-reviewed literature was searched across seven databases and identified abstracts were independently screened by two reviewers. A thematic synthesis methodology was used to code and synthesise the results from the included studies. In total, 7233 abstracts were identified; 31 articles were selected for inclusion, representing 26 physical rehabilitation interventions. The methodological quality of studies was moderate (Standards for Reporting Qualitative Research mean ± standard deviation = 14.39 ± 3.61). The four main themes developed were: (1) Benefits of physical rehabilitation, (2) Challenges of physical rehabilitation, (3) Need for support, and (4) Issue of control. This qualitative thematic synthesis provides key insights into the experiences of individuals with spinal cord injuries who received physical rehabilitation. Recommendations for practice, based on the findings, include creating a diverse, encouraging, and educational physical rehabilitation experience with supportive staff who focus on communication and person-centred care. Implications for Rehabilitation Physical rehabilitation provides psychological as well as physical benefits to people with spinal cord injuries, including motivation, hope, improved self-confidence, and acceptance. Challenges identified during physical rehabilitation for people with spinal cord injuries, such as comparisons, negative emotions, recovery expectations, and slow progress, should be addressed by healthcare professionals to ensure person-centred care. People with spinal cord injuries identified a need for support from health care professionals, family, and friends, as well other people with spinal cord injuries. There is an issue of control in physical rehabilitation for people

    Full Text Available Abstract Background Current recommendations do not support the use of continuous electronic fetal monitoring (EFM for low risk women during labour, yet EFM remains widespread in clinical practice. Consideration of the views, perspectives and experiences of individuals directly concerned with EFM application may be beneficial for identifying barriers to and facilitators for implementing evidence-based maternity care. The aim of this paper is to offer insight and understanding, through systematic review and thematic analysis, of research into professionals’ views on fetal heart rate monitoring during labour. Methods Any study whose aim was to explore professional views of fetal monitoring during labour was considered eligible for inclusion. The electronic databases of MEDLINE (1966–2010, CINAHL (1980–2010, EMBASE (1974–2010 and Maternity and Infant Care: MIDIRS (1971–2010 were searched in January 2010 and an updated search was performed in March 2012. Quality appraisal of each included study was performed. Data extraction tables were developed to collect data. Data synthesis was by thematic analysis. Results Eleven studies, including 1,194 participants, were identified and included in this review. Four themes emerged from the data: 1 reassurance, 2 technology, 3 communication/education and 4 midwife by proxy. Conclusion This systematic review and thematic analysis offers insight into some of the views of professionals on fetal monitoring during labour. It provides evidence for the continuing use of EFM when caring for low-risk women, contrary to current research evidence. Further research to ascertain how some of these views might be addressed to ensure the provision of evidence-based care for women and their babies is recommended.

    Past research into exercise among people with long-term health conditions has paid surprisingly little attention to the concept of enjoyment. This study explored enjoyment of exercise among people with arthritis. Semi-structured interviews were held with 12 participants aged 20-85 years. The transcripts were analysed using inductive thematic analysis. Four themes were identified: enjoyment of exercise in relation to other people, benefits of exercise in relation to enjoyment, working around barriers to enjoy exercise and finding an enjoyable balance to exercise. These themes highlight the relevance of enjoyment and how it could feature in advice about exercise for people with arthritis.

    Most existing image analysis systems were designed with the Landsat Multi-Spectral Scanner in mind, leaving open the question of whether or not these systems could adequately process Thematic Mapper data. In this report, both hardware and software systems have been evaluated for compatibility with TM data. Lack of spectral analysis capability was not found to be a problem, though techniques for spatial filtering and texture varied. Computer processing speed and data storage of currently existing mini-computer based systems may be less than adequate. Upgrading to more powerful hardware may be required for many TM applications.

    Full Text Available Land cover map of North Sinai was produced based on the FAO-Land Cover Classification System (LCCS of 2004. The standard FAO classification scheme provides a standardized system of classification that can be used to analyze spatial and temporal land cover variability in the study area. This approach also has the advantage of facilitating the integration of Sinai land cover mapping products to be included with the regional and global land cover datasets. The total study area is covering a total area of 20,310.4 km2 (203,104 hectare. The landscape classification was based on SPOT4 data acquired in 2011 using combined multispectral bands of 20 m spatial resolution. Geographic Information System (GIS was used to manipulate the attributed layers of classification in order to reach the maximum possible accuracy. GIS was also used to include all necessary information. The identified vegetative land cover classes of the study area are irrigated herbaceous crops, irrigated tree crops and rain fed tree crops. The non-vegetated land covers in the study area include bare rock, bare soils (stony, very stony and salt crusts, loose and shifting sands and sand dunes. The water bodies were classified as artificial perennial water bodies (fish ponds and irrigated canals and natural perennial water bodies as lakes (standing. The artificial surfaces include linear and non-linear features.

    The focus of research in simulation-based laparoscopic training has changed from examining whether simulation training works to examining how best to implement it. In laparoscopic skills training, portable and affordable box trainers allow for off-site training. Training outside simulation centers and hospitals can increase access to training, but also poses new challenges to implementation. This review aims to guide implementation of off-site training of laparoscopic skills by critically reviewing the existing literature. An iterative systematic search was carried out in MEDLINE, EMBASE, ERIC, Scopus, and PsychINFO, following a scoping review methodology. The included literature was analyzed iteratively using a thematic analysis approach. The study was reported in accordance with the STructured apprOach to the Reporting In healthcare education of Evidence Synthesis statement. From the search, 22 records were identified and included for analysis. A thematic analysis revealed the themes: access to training, protected training time, distribution of training, goal setting and testing, task design, and unsupervised training. The identified themes were based on learning theories including proficiency-based learning, deliberate practice, and self-regulated learning. Methods of instructional design vary widely in off-site training of laparoscopic skills. Implementation can be facilitated by organizing courses and training curricula following sound education theories such as proficiency-based learning and deliberate practice. Directed self-regulated learning has the potential to improve off-site laparoscopic skills training; however, further studies are needed to demonstrate the effect of this type of instructional design.

    Near-death experiences (NDEs) refer to profound psychological events that can have an important impact on the experiencers' (NDErs) lives. Previous studies have shown that NDEs memories are phenomenologically rich. In the present study, we therefore aimed to extract the common themes (referred to as "features" in the NDE literature) reported by NDErs by analyzing all the concepts stored in the narratives of their experiences. A qualitative thematic analysis has been carried out on 34 cardiac arrest survivors' NDE narratives. Our results shed the light on the structure of the narratives by identifying 10 "time-bounded" themes which refer to isolated events encountered during the NDE and 1 "transversal" theme which characterizes the whole narrative and generally appears as a retrospective comment of self-reflection on the experience. The division of narratives into themes provides us with detailed information about the vocabulary used by NDErs to describe their experience. This established thematic method enables a rigorous description of the phenomenon, ensuring the inclusion of all self-reported manifestations of themes in narratives.

    In this commentary, I review 38 articles published as editorials in Simulation in Healthcare from inception to April 2016. Of the 27 authors, there was a predominance of medical doctors (63%), male authors (67%), and work originating in the United States (86%). The founding Editor-in-Chief Dr David Gaba contributed to half of the editorials. Using inductive thematic analysis, the following five themes were identified: "embedding" simulation, simulation responding to clinical practice, educational considerations for simulation, research practices, and communicating leadership and scholarship about the community. After thematic analysis, the theoretical notion of communities of practice was used to make further meaning of the themes. This theorizing process reveals that editorial content aligns with the features of an evolving community of practice. The editorials seem to have responded to and shaped contemporary simulation practices. The editorial is a powerful forum in which to frame issues relevant to the healthcare simulation community. As the founding Editor-in-Chief, Gaba has made an extraordinary contribution to the Society for Simulation in Healthcare, in these editorials and the broader healthcare simulation community. Under the leadership of the Editor-in-Chief, Dr Mark Scerbo, I am confident that the editorial voice will continue in the true spirit of scholarship.

    UniNet is an Internet-based thematic network for a virtual community of users (VCU). It supports one multidisciplinary community of doctoral students, who receive most of the courses on the network. The evident advantages of distance learning by Internet, in terms of costs, comfort, etc., require a previous evaluation of the system, focusing on the learning outcomes of the student. The aim was to evaluate the real learning of the students of doctorate courses, by comparing the effectiveness of distance learning in UniNet with traditional classroom-based teaching. Five doctorate courses were taught simultaneously to two independent groups of students in two ways: one, through the UniNet Network, and the other in a traditional classroom. The academic knowledge of students was evaluated at the beginning and end of each course. The difference in score was considered as a knowledge increase. The comparison was made using Student's t-test for independent groups. There were no significant statistical differences in the outcomes of the two groups of students. This suggests that both teaching systems were equivalent in increasing the knowledge of the students. Both educational methods, the traditional system and the online system in a thematic network, are effective and similar for increasing knowledge.

Each interpretation book as a written discourse is different from each other due to author’s cognition frame. This study employs a constructive qualitative approach with technical framing analysis. The data are language data (religious text that are obtainable from thematic interpretation of the Koran of the Ministry of Religious Affairs of the Republic of Indonesia. Data analysis was performed on the following topics: the origins of the creation of men and women, women's leadership, women and inheritance rights, women and ownership, and women's testimony. The research findings show: (1 The lingual and religious discourse containing gender cognition are present in the forms of words, phrases, and sentences. The lingual form of religious discourse is related to the meaning of technical vocabulary that contains appropriate understanding of the discourse topic. (2 Discourse representing gender cognition is found on three topics: women leadership (nation leadership, waris (inheritance, and women’s testimony. In terms of inheritance and women’s testimony, this interpretation refers to conditions that are explicitly stated in the Holy Koran. Meanwhile, this interpretation views leadership of the nation as more worthy to be given to men than women. book looks is more worthy of leadership in the countries was given to men than women.

    Autobiographical memory research has investigated how cueing distinct aspects of a past event can trigger different recollective experiences. This research has stimulated theories about how autobiographical knowledge is accessed and organized. Here, we test the idea that thematic information organizes multiple autobiographical events whereas spatial information organizes individual past episodes by investigating how retrieval guided by these two forms of information differs. We used a novel autobiographical fluency task in which participants accessed multiple memory exemplars to event theme and spatial (location) cues followed by a narrative description task in which they described the memories generated to these cues. Participants recalled significantly more memory exemplars to event theme than to spatial cues; however, spatial cues prompted faster access to past memories. Results from the narrative description task revealed that memories retrieved via event theme cues compared to spatial cues had a higher number of overall details, but those recalled to the spatial cues were recollected with a greater concentration on episodic details than those retrieved via event theme cues. These results provide evidence that thematic information organizes and integrates multiple memories whereas spatial information prompts the retrieval of specific episodic content from a past event.

    Full Text Available The geodiversity hotspot comprising 14 geological heritage sites is located on the territory of Mountainous Adygeja in the Western Caucasus (southwestern Russia. The geosites represent some lengthy intervals of the geological history from the Precambrian to the Quaternary, as well as changes in the palaeotectonical affinity of the Greater Caucasus. Visitors of this territory can observe rocks, fossils, and facies, which are typical for the geological periods, especially the Permian, the Triassic, and Jurassic, and the Cretaceous. The same geosites permit to trace shift of the Greater Caucasus Terrane from the Gondwanan margin, where it was before the Devonian, to Laurussia and then Laurasia. Therefore, the geosites can be grouped thematically to facilitate arrangement of geoconservation and geotourism activities. This approach permits to increase the scientific and educational values of the geological heritage in Mountainous Adygeja and to make it more attractive for geotourists. However, such a thematic treatment of the regional geological heritage should not lead to underestimation of the other geological features.

    2013-10-01

    The aim of this review was to systematically identify and synthesise all qualitative evidence on how adult patients diagnosed with acute leukaemia experience living with their illness. A systematic search strategy was developed comprising of two search strings: i) acute leukaemia and ii) qualitative methodology. The search strategy was run in seven electronic databases (Medline, CINAHL, PsychINFO, EMBASE, BNI & Archive, SSCI and ASSIA). Nine qualitative studies in adult patients with acute leukaemia, published in peer reviewed journals between 01/1990 and 01/2013 were included in the final sample. The qualitative thematic synthesis resulted in the development of a conceptual model describing a person's path to build a renewed self. Following the initial blow of diagnosis with the range of initial reactions, patients with acute leukaemia are living in a contracting world; they have to deal with the life in hospital, the several losses and the impact of their illness on their emotions and interpersonal relationships. Several factors take up a buffering role at that stage: coping, support, information and hope. Finally, patients accommodate acute leukaemia in their lives through re-evaluating personal values and assigning new meaning to their experience. Results from this thematic synthesis are indicative of the impact of acute leukaemia on patients' lives and the processes they use to make sense and accommodate the illness in their life. Increasing our understanding of these processes is warranted to improve patient care. Copyright © 2013. Published by Elsevier Ltd.

    To review the literature and investigate the meaning of hope to patients receiving palliative care and to examine the themes that foster hope in those patients. Hope is often linked to the future and is a significant factor for patients dealing with adversity, such as a terminal illness. The concept of hope is underreported in the literature. Mixed method thematic review. CINAHL, Scopus, PsychINFO, Informit, PubMed, Science Direct, ProQuest, Web of Science and Google Scholar online databases were searched using keywords and inclusion and exclusion criteria published between 2003-2013. Twelve qualitative articles were thematically analysed using Braun and Clarke's (2006) steps to ascertain major themes and sub-themes. On analysis, the remaining three mixed method studies were found to reflect the themes generated by the qualitative studies. Seven key themes that increased hope were found: disease status; positive personal relationships; positive character traits; quality of life; setting and achieving goals; spirituality/religion; and hope after death. The importance of hope to dying patients was established. Hope is a very complex and personal phenomena requiring hope-enhancing strategies to be individualized. More research is needed with groups whose culture, youth or type of illness may affect their ability to foster and maintain hope. © 2015 John Wiley & Sons Ltd.

    1987-01-01

    Pinyon-Juniper woodlands dominate approximately 24.3 million hectares (60 million acres) in the western United States. The overall objective was to test the sensitivity of the LANDSAT Thematic Mapper (TM) spectral data for detecting varying degrees of soil erosion within the Pinyon-Juniper woodlands. A second objective was to assess the potential of the spectral data for assigning the Universal Soil Loss Equation (USLE) crop management (C) factor values to varying cover types within the woodland. Thematic Mapper digital data for June 2, 1984 on channels 2, 3, 4, and 5 were used. Digital data analysis was performed using the ELAS software package. Best results were achieved using CLUS, an unsupervised clustering algorithm. Fifteen of the 40 Pinyon-Juniper signatures were identified as being relatively pure Pinyon-Juniper woodland. Final analysis resulted in the grouping of the 15 signatures into three major groups. Ten study sites were selected from each of the three groups and located on the ground. At each site the following field measurements were taken: percent tree canopy and percent understory cover, soil texture, total soil loss, and soil erosion rate estimates. A technique for measuring soil erosion within Pinyon-Juniper woodlands was developed. A theoretical model of site degradation after Pinyon-Juniper invasion is presented.

  11. Smart "geomorphological" map browsing - a tale about geomorphological maps and the internet

    Science.gov (United States)

    Geilhausen, M.; Otto, J.-C.

    2012-04-01

    With the digital production of geomorphological maps, the dissemination of research outputs now extends beyond simple paper products. Internet technologies can contribute to both, the dissemination of geomorphological maps and access to geomorphologic data and help to make geomorphological knowledge available to a greater public. Indeed, many national geological surveys employ end-to-end digital workflows from data capture in the field to final map production and dissemination. This paper deals with the potential of web mapping applications and interactive, portable georeferenced PDF maps for the distribution of geomorphological information. Web mapping applications such as Google Maps have become very popular and widespread and increased the interest and access to mapping. They link the Internet with GIS technology and are a common way of presenting dynamic maps online. The GIS processing is performed online and maps are visualised in interactive web viewers characterised by different capabilities such as zooming, panning or adding further thematic layers, with the map refreshed after each task. Depending on the system architecture and the components used, advanced symbology, map overlays from different applications and sources and their integration into a Desktop GIS are possible. This interoperability is achieved through the use of international open standards that include mechanisms for the integration and visualisation of information from multiple sources. The portable document format (PDF) is commonly used for printing and is a standard format that can be processed by many graphic software and printers without loss of information. A GeoPDF enables the sharing of geospatial maps and data in PDF documents. Multiple, independent map frames with individual spatial reference systems are possible within a GeoPDF, for example, for map overlays or insets. Geospatial functionality of a GeoPDF includes scalable map display, layer visibility control, access to attribute

  12. Generating Topographic Map Data from Classification Results

    2017-03-01

    Full Text Available The use of classification results as topographic map data requires cartographic enhancement and checking of the geometric accuracy. Urban areas are of special interest. The conversion of the classification result into topographic map data of high thematic and geometric quality is subject of this contribution. After reviewing the existing literature on this topic, a methodology is presented. The extraction of point clouds belonging to line segments is solved by the Hough transform. The mathematics for deriving polygons of orthogonal, parallel and general line segments by least squares adjustment is presented. A unique solution for polylines, where the Hough parameters are optimized, is also given. By means of two data sets land cover maps of six classes were produced and then enhanced by the proposed method. The classification used the decision tree method applying a variety of attributes including object heights derived from imagery. The cartographic enhancement is carried out with two different levels of quality. The user’s accuracies for the classes “impervious surface” and “building” were above 85% in the “Level 1” map of Example 1. The geometric accuracy of building corners at the “Level 2” maps is assessed by means of reference data derived from ortho-images. The obtained root mean square errors (RMSE of the generated coordinates (x, y were RMSEx = 1.2 m and RMSEy = 0.7 m (Example 1 and RMSEx = 0.8 m and RMSEy = 1.0 m (Example 2 using 31 and 62 check points, respectively. All processing for Level 1 (raster data could be carried out with a high degree of automation. Level 2 maps (vector data were compiled for the classes “building” and “road and parking lot”. For urban areas with numerous classes and of large size, universal algorithms are necessary to produce vector data fully automatically. The recent progress in sensors and machine learning methods will support the generation of topographic map data of high

    Full Text Available This study was designed to verify the effect of thematic classes on English vocabulary learning. Thematic class is an educational project, which recently started to be used in junior high schools in Iran. The ministry of Education in Iran has launched the project of thematic classes to improve learning in 2010 with the hope of copying with some of the educational problems so that students experience deeper learning.  For subjects of the study, 90 7th grade students of junior high school in Taybad, Khorasan e Razavi were selected. Three groups were used in this study: two experimental groups and one control group. Each group consisted of 30 female students, who settled randomly in the groups, respectively. Their range of age was between 13 and 14. A vocabulary-based test, which was designed by the researcher, was used as the main measurement tool in the study to evaluate the students' achievement in the course. The course lasted 10 weeks, two sessions per week. The results reflected the positive effect of thematic classes on vocabulary learning. Therefore, educational implication of thematic class for junior high school is suggestible.

  15. An Analysis of the High Frequency Vibrations in Early Thematic Mapper Scenes

    Kogut, J.; Larduinat, E.

    1985-01-01

    The motion of the mirrors in the thematic mapper (TM) and multispectral scanner (MSS) instruments, and the motion of other devices, such as the TDRSS antenna drive, and solar array drives onboard LANDSAT-4 cause vibrations to propagate through the spacecraft. These vibrations as well as nonlinearities in the scanning motion of the TM mirror can cause the TM detectors to point away from their nominal positions. Two computer programs, JITTER and SCDFT, were developed as part of the LANDSAT-D Assessment System (LAS), Products and Procedures Analysis (PAPA) program to evaluate the potential effect of high frequency vibrations on the final TM image. The maximum overlap and underlap which were observed for early TM scenes are well within specifications for the ground processing system. The cross scan and scan high frequency vibrations are also within the specifications cited for the flight system.

    2017-09-01

    To identify and describe the activities performed by online support community moderators. A total of 790 messages were downloaded for analysis. Messages were written by 59 moderators from 6 forums that represent a diverse range of conditions (arthritis, complex regional pain syndrome, Crohn's disease, depression, diabetes and Huntington's disease). Thematic analysis revealed four themes: supportive tasks supportive tasks involve providing help to members, moderators sharing experiences shows how they use forums to fulfil their own personal support needs, making announcements about new discoveries and upcoming events, and administrative tasks such as enforcing rules and deleting spam. These results are consistent with the helper-therapy principle and provide a new insight into the diverse and varied range of activities carried out by moderators. Moderators perform many roles, including using forums for their own support needs. Copyright © 2017 Elsevier B.V. All rights reserved.

    2007-01-01

    The neutron flux in a research reactor can be used in several applications such as the neutron activation analysis, the radioisotopes production, study of DNA and protein structures, doping of silicon and neutron radiography. The enhancement of the nuclear research reactor utilization with the introduction of new applications would be possible with the availability of a neutron beam and with the neutron energy spectra completely characterized. This work evaluates the use of TRIGA reactor of CDTN/CNEN as a source of neutron beam. The readiness of a neutron beam with appropriate intensity and energy spectrum would make possible the increasing of the thematic of applications and researches in this reactor. The main contribution to this theme is to evaluate the thermal and epithermal neutron flux in the vertical extractor of the TRIGA IPR-R1. The simulation was performed in this work using the MCNP code. (author)

    Grogan, Sarah; Mechan, Jayne

    2017-09-01

    This study investigated younger women's body image after mastectomy. In all, 49 women, aged 29-53 years (mean age: 39 years) who had had bilateral ( n = 8) or unilateral ( n = 41) mastectomy responded to open-ended questions online. Inductive thematic analysis revealed that aesthetics were less important than survival between diagnosis and mastectomy. Following mastectomy, women negotiated new body identities. Treatment effects such as weight gain were significant concerns. However, impacts on body confidence varied, and some participants rejected mainstream body shape ideals and reported feeling proud of their scars. Implications for supporting younger women post-mastectomy, including promotion of body acceptance, are discussed.

    International Nuclear Information System (INIS)

    Clark, Sarah; Reeves, Pauline J.

    2015-01-01

    Aim: The aim of this study was to analyse relevant literature to understand women's experiences of mammography-both screening and symptomatic. Method: A structured literature search was performed to locate relevant research. Research articles published between 2002 and 2013 were identified in CINAHL, MEDLINE and Science Direct. The quality of the research was assessed using an appropriate critical appraisal tool to enable a systematic and consistent assessment. Results: Qualitative thematic analysis of the literature identified five themes: fear, pain and discomfort, waiting, the physical environment and staff interactions. Whilst it is accepted that women's experiences are unique and diverse, literature suggested that these themes do influence women's experiences. Conclusion: Women's experiences of mammography were not limited to the examinations alone but encompassed the entire encounter. The themes identified influenced women's experiences and their perception of care

    2001-01-01

    Accurate measurements of workplace exposure to 232 Th and its progeny are required to estimate internal radiation doses received by persons working with thorium-containing materials. However, a small intercomparison carried out in the mid-nineteen nineties raised doubts about the reliability of results obtained by methods available for measurement of thorium. An EC-funded thematic network was therefore established to bring together experts in the field of thorium analysis in order to coordinate research activity and identify best analytical practice, requirements for reference materials, etc. This network has now successfully completed its work programme, which included a survey to determine future research needs; a series of intercomparisons to test the performance of methods for measuring thorium in workplace materials, and a workshop held to promote best practice and transfer information to regulatory authorities and industry. Results of the work have been used to make various recommendations concerning future needs in this field. (author)

    Medical students experience more psychological distress than the general population. One contributing factor is mistreatment. This study aims to understand the mechanisms of mistreatment as perceived by medical students. Students completed anonymous surveys during the first and last didactic session of their surgery clerkship in which they defined and gave examples of mistreatment. Team-based thematic analysis was performed on responses. Between January 2014 and June 2016, 240 students participated in the surgery clerkship. Eighty-nine percent of students completed a survey. Themes observed included (1) Obstruction of Students' Learning, (2) Exploitation of Student Vulnerability, (3) Exclusion from the Medical Team, and (4) Contextual Amplifiers of Mistreatment Severity. The themes observed in this study improve our understanding of the students' perspective on mistreatment as it relates to their role in the clinical learning context, which can serve as a starting point for interventions that ultimately improve students' experiences in the clinical setting.

    1984-01-01

    An approach for atmospheric particulate concentration evaluation above urban areas using ratio Thematic Mapper (TM) data is discussed. October 25, 1982 TM data over Chicago, IL are analyzed using TM band ratios of 1/2, 1/3, 1/4, 1/5, and 1/6 and particulate concentration estimates derived from TM ratios are tested over low reflective turbid water sites and highly reflective concrete highways. From analysis of the data it is evident that for water, the pattern of increasing particulate concentration is associated with decreasing ratio values in all band combinations used. Over concrete features, the TM band 1/4 ratio values follow the predicted pattern, while the TM band 1/6 has ratios which are reversed from anticipated values.

    Landsat Thematic Mapper provides valuable information on biomass burning, such as the apparent temperature of a fire and its shape. However, the surface determined by remote sensing does not exactly correspond to the burning area, due to an artificial enlargement of the fire front width. This enlargement of the fire front width. This enlargement may have diverse origins. In particular, it is difficult to estimate the temperature of the areas that are behind the fire front and that have been just burned. Emissions from these areas may be detectable by Landsat channels, thus resulting in the observed enlargement of the fire front. Additional experiments including remote sensing by plane are necessary to allow a more complete understanding of these phenomena. Biomass burning is an important source of atmospheric pollution on a global scale. This study indicates that a fire is a significant source of pollution on a local scale

    International Nuclear Information System (INIS)

    1998-01-01

    Objective: To support livestock development programmes aiming at controlling or eradicating key insect pests. This involves the application of the sterile insect technique (SIT) into area wide integrated pest management and eradication systems. The sustainability of eradication activities has been demonstrated for a number of insect pests under various national settings where the application of SIT has produced significant impact on socio-economic development, in terms of both cost-savings and environmental quality. In line with the TC strategy, this thematic plan reviews best practices and experience gained in field operations, identifies stakeholders and common objectives in New World Screwworm, Cochliomya hominivorax (NWS) and Old World Screwworm, Chrysomya bezziana (OWS), control and outlines a strategy for implementing integrated pest control programmes at the regional, sub-regional and national level. Synergies are sought with partner organisations to expand the knowledge base and capabilities for SIT based pest control activities and to strengthen TCDC.

    1984-01-01

    The utility of Landsat MSS classification methods in the case of small, highly urbanized hydrological basins containing complex land-use patterns is limited, and is plagued by misclassifications due to the spectral response similarity of many dissimilar surfaces. Landsat MSS data for the Conley Creek basin near Atlanta, Georgia, have been compared to thematic mapper simulator (TMS) data obtained on the same day by aircraft. The TMS data were able to alleviate many of the recurring patterns associated with MSS data, through bandwidth optimization, an increase of the number of spectral bands to seven, and an improvement of ground resolution to 30 m. The TMS is thereby able to detect small water bodies, powerline rights-of-way, and even individual buildings.

    1985-01-01

    Analysis of the early thematic mapper (TM) data indicate the TM sensor and associated ground processing are performing equal to the high expectations and within advertised specifications. The overall TM system with improved resolution, together with additional and more optimumly placed spectral bands shows much promise for benefits in future analysis activities. By selecting man-made features of known dimensions (e.g., highways, airfields, buildings, and isolated water bodies), an assessment was made of the TM performance relative to the specified 30-meter (98-foot) resolution. The increase of spatial resolution of TM (30 m) over MSS (80 M) appears to be significant not only in resolving spectrally distinct classes that were previously undefinable but also in distinguishing within-field variability. An Important result of the early TM evaluation and pre-TM analyses was the development of an integrated system to receive LANDSAT-4 TM (as well as MSS) data and analyze the data via various approaches.

    2018-01-01

    The aim of this study is to understand the behaviors experienced nurse executives use to create healthy work environments (HWEs). The constructs of authentic leadership formed the conceptual framework for the study. The American Association of Critical-Care Nurses recommends authentic leadership as the preferred style of leadership for creating and sustaining HWEs. Behaviors associated with authentic leadership in nursing are not well understood. A purposive sample of 17 experienced nurse executives were recruited from across the United States for this qualitative study. Thematic analysis was used to analyze the in-depth, semistructured interviews. Four constructs of authentic leaders were supported and suggest unique applications of each including self-awareness (a private and professional self), balanced processing (open hearted), transparency (limiting exposure), and moral leadership (nursing compass). Authentic leadership may provide a sound foundation to support nursing leadership practices; however, its application to the discipline requires additional investigation.

    Full Text Available The pedagogical work with mathematical modeling assumes investigate situations of reality. However, mental models formed from the contact with the experiential world are generally incompatible with the conceptual models. So David Hestenes supports the view that one of the biggest challenges of teaching and learning in science and mathematics is to coordinate conceptual models with mental models, which led to the elaboration of a didactic in mathematical modeling: Modeling Instruction. Our goal is to present a proposal for thematic modeling cycle drawn up in hestenesianos assumptions and discuss possibilities for scientific literacy. The main question was to know how to emerge indicators for scientific literacy for the proposed cycle. This is a bibliographic research in order to identify the available literature contributions on the subject and raise the possibility and challenges for the brazilian teaching science and mathematics. Preliminary results indicate that the proposed modeling cycle can develop indicators for scientific literacy of different natures.

    Patient information and education, such as decision aids, are gradually moving toward online, computer-based environments. Considerable research has been conducted to guide content and presentation of decision aids. However, given the relatively new shift to computer-based support, little attention has been given to how multimedia and interactivity can improve upon paper-based decision aids. The first objective of this review was to summarize published literature into a proposed classification of features that have been integrated into computer-based decision aids. Building on this classification, the second objective was to assess whether integration of specific features was associated with higher-quality decision making. Relevant studies were located by searching MEDLINE, Embase, CINAHL, and CENTRAL databases. The review identified studies that evaluated computer-based decision aids for adults faced with preference-sensitive medical decisions and reported quality of decision-making outcomes. A thematic synthesis was conducted to develop the classification of features. Subsequently, meta-analyses were conducted based on standardized mean differences (SMD) from randomized controlled trials (RCTs) that reported knowledge or decisional conflict. Further subgroup analyses compared pooled SMDs for decision aids that incorporated a specific feature to other computer-based decision aids that did not incorporate the feature, to assess whether specific features improved quality of decision making. Of 3541 unique publications, 58 studies met the target criteria and were included in the thematic synthesis. The synthesis identified six features: content control, tailoring, patient narratives, explicit values clarification, feedback, and social support. A subset of 26 RCTs from the thematic synthesis was used to conduct the meta-analyses. As expected, computer-based decision aids performed better than usual care or alternative aids; however, some features performed better than

    Full Text Available Abstract The Scoliosis Rehabilitation model begins with the correct diagnosis and evaluation of the patient, to make treatment decisions oriented to the patient. The treatment is based on observation, education, scoliosis specific exercises, and bracing. The state of research in the field of conservative treatment is insufficient. There is some evidence supporting scoliosis specific exercises as a part of the rehabilitation treatment, however, the evidence is poor and the different methods are not known by most of the scientific community. The only way to improve the knowledge and understanding of the different physiotherapy methodologies (specific exercises, integrated into the whole rehabilitation program, is to establish a single and comprehensive source of information about it. This is what the SCOLIOSIS Journal is going to do through the "Rehabilitation Schools for Scoliosis" Thematic Series, where technical papers coming from the different schools will be published.

    2016-01-01

    With the growing diversity in the United States among both clinicians and clients, many therapeutic encounters are cross-cultural, requiring providers to connect across cultural differences. Foreign-born therapists have many areas of differences to work through. Thus, exploring how foreign-born family therapists in the United States connect to their clients can uncover helpful strategies that all therapists can use to establish stronger cross-cultural therapeutic connections. A thematic analysis was conducted to understand strategies 13 foreign-born therapists used during therapeutic encounters. Four themes were identified: making therapy a human-to-human connection, dealing with stereotypes, what really matters, and flexibility. Findings suggest that developing a deep therapeutic connection using emotional attunement and human-to-human engagement is crucial for successful cross-cultural therapy.

    García Ureta, Irene

    2007-11-01

    The aims of this study were twofold. On the one hand, to reach an understanding of, and to illustrate the experience of addictive buying and, on the other, to throw some light on the controversial subject of addicts' personal responsibility for their behavior. With these aims, a thematic analysis of an extensive diary written by a compulsive buyer is presented. Four themes emerge from the analysis: the defining characteristics of addiction to buying that determine the boundary separating it from other forms of impulsive or careless buying; several causal factors; the role that money and material objects play in family relationships and friendships through the symbolic meanings they adopt; and the relationship of personal values with impulsiveness and self-control. In view of the results, the moral model of addiction to buying is discussed, and an explanatory model of the ambivalence that is characteristic of addiction to buying is proposed, based on a personal hierarchy of values.

Slow movements have emerged in relation to a number of topics: Slow food, Citta slow and more recently, slow science. What motivated us in the seminars was to explore how far these movements could help us address the acceleration and intensification of work within our own and other universities, and indeed, what new learning, research, philosophies, practices, structures and governance might emerge. This editorial introduction presents the concept of the "slow university" and introduces our critical engagements with slow. The articles presented here interrogate the potentialities, challenges, problems and pitfalls of the slow university in an era of corporate culture and management rationality.

    2016-12-01

    Using thematic analysis, this study explores the motivation to commit sexual homicide from the perspective of the perpetrator. In the process, it revisits motivational models and offender typologies that have been put forward to explain such offenses. From the homicide narratives of eight sexual homicide offenders detained in a high security hospital in the United Kingdom, four themes were found which appeared significant in terms of understanding the offenses committed. These themes were labeled as follows: (a) avenging sexual abuse, (b) events leading to a catathymic reaction, (c) homicidal impulse, and (d) emotional loneliness. Although these findings are not inconsistent with previous research, we argue that the current literature fails to capture the complexity associated with these offenses. We also argue that the context or situation in which sexual homicide occurs is a crucial feature of the offense, and one which has not been adequately taken into account by motivational models. © The Author(s) 2015.

    The purpose of this thematic synthesis was to review qualitative studies on perspectives of persons with intellectual disabilities regarding friendships and intimate relationships. A literature search was conducted, including studies published between 2004 and 2014, involving participants 14 years of age or older, who had intellectual disabilities, and participated in focus groups or interviews. Eighteen studies were included. Three master themes were identified: (i) How do I know someone is my friend? (ii) How do I know someone is my boyfriend or girlfriend? and (iii) What helps and hinders relationships? Understanding how people with intellectual disabilities describe relationships, and being aware of factors that support and impede relationships, will aid stakeholders in developing training, policies, programmes and services. Knowledge translation of research that focuses on strategies aimed at supporting relationships is crucial to affect change in applied settings and improve quality of life for persons with intellectual disabilities. © 2016 John Wiley & Sons Ltd.

    In the face of scarcity, nurses may inevitably delay or omit some nursing interventions and give priority to others. This increases the risk of adverse patient outcomes and threatens safety, quality, and dignity in care. However, it is not clear if there is an ethical element in nursing care rationing and how nurses experience the phenomenon in its ethical perspective. The purpose was to synthesize studies that relate care rationing with the ethical perspectives of nursing, and find the deeper, moral meaning of this phenomenon. A systematic review and thematic synthesis of qualitative studies was used. Searching was based on guidelines suggested by Joana Brigs Institute, while the synthesis has drawn from the methodology described. Primary studies were sought from nine electronic databases and manual searches. The explicitness of reporting was assed using consolidated criteria for reporting qualitative research. Nine studies involving 167 nurse participants were included. Synthesis resulted in 35 preliminary themes, 14 descriptive themes, and four analytical themes (professional challenges and moral dilemmas, dominating considerations, perception of a moral role, and experiences of the ethical effects of rationing). Discussion of relationships between themes revealed a new thematic framework. Every effort has been taken, for the thoroughness in searching and retrieving the primary studies of this synthesis, and in order for them to be treated accurately, fairly and honestly and without intentional misinterpretations of their findings. Within limitations of scarcity, nurses face moral challenges and their decisions may jeopardize professional values, leading to role conflict, feelings of guilt, distress and difficulty in fulfilling a morally acceptable role. However, more research is needed to support certain relationships. Related literature is limited. The few studies found highlighted the essence of justice, equality in care and in values when prioritizing care

    Anecdotal evidence and qualitative research attest to the importance of work-family interactions pre-, during and post-missions. This study uses thematic content analysis to quantify characteristics of work-family interactions and how these changed by stage of cosmonauts' career, identifying the effect of space career variables (e.g., time in space and station) on such interactions during and post-career. Using a thematic scoring scheme developed for this study, we coded work-family interactions identified from interviews with 20 retired male cosmonauts. The majority of work-family interactions were ones in which work overlapped into family life and work hindered or interfered with the family situation. The most common resolution was that family adjusted to work, and the mood or tone about this outcome was almost equally divided among negative, positive and neutral. Changes in work-family interactions and their resolution over the cosmonaut's life showed that the significant interactions were most evident during the cosmonaut career. Although the cosmonaut career has high work demands, it did adjust for family when the need arose. The Russian Space Agency (RKS) eased the impact of the periodic absences, especially through regular communication sessions. Positive work-family interactions, i.e., work or family helping the opposite role, were more likely for those who had been on ISS, not Mir, and for those whose last flight was after 2000. Our data reflect retired cosmonauts' recollections of work-family interactions during their career. Examples of work overlapping into family life and work viewed as interfering with family life were possibly more salient or better remembered than work or family helping the other role.

    Patients with brachial plexus injury (BPI) and their family members contribute to Internet discussion groups dedicated to BPI. We hypothesized that a thematic analysis of posts from BPI Internet discussion groups would reveal common themes related to the BPI patient experience, providing topics for patient education and counseling. Internet discussion boards were identified using the search term "brachial plexus injury support group" in Google, Bing, and Yahoo! search engines. Two discussion boards had substantially more posts than other Web sites and were chosen for analyses. Posts from January 1, 2015, through January 1, 2016, were examined. Using an iterative and established process, 2 investigators (M.T.M. and C.J.D) independently analyzed each post using thematic analysis in 3 steps (open coding, axial coding, and selective coding) to determine common themes. In this process, each post was reviewed 3 times. A total of 328 posts from the 2 leading discussion boards were analyzed. Investigators reached a consensus on themes for all posts. One central theme focused on emotional aspects of BPI. Four other central themes regarding information support were identified: BPI disease, BPI treatment, recovery after BPI treatment, and process of seeking care for BPI. Examination of posts on Internet support groups for BPI revealed recurring concerns, questions, and opinions of patients and their family members. The most common themes related to disease information, treatment, recovery, and the emotional element of BPI. These findings provide a helpful starting point in refining topics for patient education and support that are targeted on patients' interests and concerns.

    Clinical supervision is essential for development of health professional students and widely recognised as a significant factor influencing student learning. Although considered important, delivery is often founded on personal experience or a series of predetermined steps that offer standardised behavioural approaches. Such a view may limit the capacity to promote individualised student learning in complex clinical environments. The objective of this review was to develop a comprehensive understanding of what is considered 'good' clinical supervision, within health student education. The literature provides many perspectives, so collation and interpretation were needed to aid development and understanding for all clinicians required to perform clinical supervision within their daily practice. A comprehensive thematic literature review was carried out, which included a variety of health disciplines and geographical environments. Literature addressing 'good' clinical supervision consists primarily of descriptive qualitative research comprising mostly small studies that repeated descriptions of student and supervisor opinions of 'good' supervision. Synthesis and thematic analysis of the literature resulted in four 'competency' domains perceived to inform delivery of learning-focused or 'good' clinical supervision. Domains understood to promote student learning are co-dependent and include 'to partner', 'to nurture', 'to engage' and 'to facilitate meaning'. Clinical supervision is a complex phenomenon and establishing a comprehensive understanding across health disciplines can influence the future health workforce. The learning-focused clinical supervision domains presented here provide an alternative perspective of clinical supervision of health students. This paper is the first step in establishing a more comprehensive understanding of learning-focused clinical supervision, which may lead to development of competencies for clinical supervision. © 2016 John Wiley

    To explore women's birth experiences to develop an understanding of their perspectives on patient safety during hospital-based birth. Qualitative description using thematic analysis of interview data. Seventeen women ages 29 to 47 years. Women participated in individual or small group interviews about their birth experiences, the physical environment, interactions with clinicians, and what safety meant to them in the context of birth. An interdisciplinary group of five investigators from nursing, medicine, product design, and journalism analyzed transcripts thematically to examine how women experienced feeling safe or unsafe and identify opportunities for improvements in care. Participants experienced feelings of safety on a continuum. These feelings were affected by confidence in providers, the environment and organizational factors, interpersonal interactions, and actions people took during risk moments of rapid or confusing change. Well-organized teams and sensitive interpersonal interactions that demonstrated human connection supported feelings of safety, whereas some routine aspects of care threatened feelings of safety. Physical and emotional safety are inextricably embedded in the patient experience, yet this connection may be overlooked in some inpatient birth settings. Clinicians should be mindful of how the birth environment and their behaviors in it can affect a woman's feelings of safety during birth. Human connection is especially important during risk moments, which represent a liminal space at the intersection of physical and emotional safety. At least one team member should focus on the provision of emotional support during rapidly changing situations to mitigate the potential for negative experiences that can result in emotional harm.

    Quality of life of patients receiving dialysis has been rated as poor. To synthesize the views of Canadian patients on or nearing dialysis, and those who care for them. Secondary analysis of a survey, distributed through dialysis centres, social media and the Kidney Foundation of Canada. Pan-Canadian convenience sample. Patients, their caregivers and health-care providers. Text responses to open-ended questions on topics relevant to end-stage renal disease. Statements related to needs, beliefs or feelings were identified, and were analysed by thematic content analysis. A total of 544 relevant statements from 189 respondents were included for the thematic content analysis. Four descriptive themes were identified through the content analysis: gaining knowledge, maintaining quality of life, sustaining psychosocial wellbeing and ensuring appropriate care. Respondents primarily identified a need for more information, better communication, increased psychosocial and financial support for patients and their families and a strong desire to maintain their previous lifestyle. Convenience sample; questions were originally asked with a different intent (to identify patient-important research issues). Patients on or nearing dialysis and their caregivers identified four major themes, gaining knowledge, maintaining quality of life, sustaining psychosocial wellbeing and ensuring appropriate care, several of which could be addressed by the health care system without requiring significant resources. These include the development of patient materials and resources, or sharing of existing resources across Canadian renal programs, along with adopting better communication strategies. Other concerns, such as the need for increased psychosocial and financial support, require consideration by health care funders.

    The aim of this paper was to identify the key factors of case management (CM) interventions among frequent users of healthcare services found in empirical studies of effectiveness. Thematic analysis review of CM studies. We built on a previously published review that aimed to report the effectiveness of CM interventions for frequent users of healthcare services, using the Medline, Scopus and CINAHL databases covering the January 2004-December 2015 period, then updated to July 2017, with the keywords 'CM' and 'frequent use'. We extracted factors of successful (n=7) and unsuccessful (n=6) CM interventions and conducted a mixed thematic analysis to synthesise findings. Chaudoir's implementation of health innovations framework was used to organise results into four broad levels of factors: (1) ,environmental/organisational level, (2) practitioner level, (3) patient level and (4) programme level. Access to, and close partnerships with, healthcare providers and community services resources were key factors of successful CM interventions that should target patients with the greatest needs and promote frequent contacts with the healthcare team. The selection and training of the case manager was also an important factor to foster patient engagement in CM. Coordination of care, self-management support and assistance with care navigation were key CM activities. The main issues reported by unsuccessful CM interventions were problems with case finding or lack of care integration. CM interventions for frequent users of healthcare services should ensure adequate case finding processes, rigorous selection and training of the case manager, sufficient intensity of the intervention, as well as good care integration among all partners. Other studies could further evaluate the influence of contextual factors on intervention impacts. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Research suggests that aggressive individuals exhibit a strong tendency to attribute hostile intent to the behavior of others when confronted with an ambiguous social situation. The vignettes method has become a standard procedure to assess hostile attributions. Vignettes represent incomplete ambiguous social stories, in which the subjects experience a negative outcome and are asked to attribute intent to the provocateur's action. This article explores the ways in which subjects perceive ambiguous social situations and other people's intentions, their tendency to refer negative outcome to oneself, and the components defining hostility in the interpersonal relationships. The sample consisted of male adolescent violent offenders ( N = 45) recruited from the Social Therapy Department of the German correctional facility for juvenile offenders in Berlin. All offenders were incarcerated for a violent or sexual crime and were currently undergoing individual and group psychotherapy. The five hypothetical vignettes used in this study were originally designed to assess hostile attributions in both institutional and noninstitutional social situations. Participants' responses were analyzed using thematic analysis. Thematic analysis revealed three key themes regarding the social perception-positive, negative, and neutral-and two themes regarding the components of hostility-provocateur-related personality features and relationship type. Although the vignettes were originally developed to detect hostility-prone perception bias, they seem to be able to reveal a wider set of different attributions of intent, both positive and negative. Thus, vignettes are not limited to assessment of hostility specifically. They much rather seem to be a measure which is sensitive to diverse attributions of intent in general. The diagnostic qualities of the vignettes, their area of application, limitations of the study, and future perspective are discussed.

  8. Medical students' perceptions of a novel institutional incident reporting system : A thematic analysis.

    2017-10-01

    Errors in healthcare are a major patient safety issue, with incident reporting a key solution. The incident reporting system has been integrated within a new medical curriculum, encouraging medical students to take part in this key safety process. The aim of this study was to describe the system and assess how students perceived the reporting system with regards to its role in enhancing safety. Employing a thematic analysis, this study used interviews with medical students at the end of the first year. Thematic indices were developed according to the information emerging from the data. Through open, axial and then selective stages of coding, an understanding of how the system was perceived was established. Analysis of the interview specified five core themes: (1) Aims of the incident reporting system; (2) internalized cognition of the system; (3) the impact of the reporting system; (4) threshold for reporting; (5) feedback on the systems operation. Selective analysis revealed three overriding findings: lack of error awareness and error wisdom as underpinned by key theoretical constructs, student support of the principle of safety, and perceptions of a blame culture. Students did not interpret reporting as a manner to support institutional learning and safety, rather many perceived it as a tool for a blame culture. The impact reporting had on students was unexpected and may give insight into how other undergraduates and early graduates interpret such a system. Future studies should aim to produce interventions that can support a reporting culture.

    Physicians in both Western and Eastern countries are being confronted by changes in health care delivery systems and medical professionalism values. The traditional concept of "In-Sul" (benevolent art) and the modern history of South Korea have led to cultural differences between South Korea and other countries in conceptualizing medical professionalism; thus, we studied medical students' perceptions of professionalism as described in essays written on this topic. In 2014, we asked 109 first-year medical students who were enrolled in a compulsory ethics course to anonymously write a description of an instance of medical professionalism that they had witnessed, as well as reflecting on their own professional context. We then processed 105 valid essays using thematic content analysis with computer-assisted qualitative data analysis software. Thematic analysis of the students' essays revealed two core aspects of professionalism in South Korea, one focused on respect for patients and the other on physicians' accountability. The most common theme regarding physician-patient relationships was trust. By contrast, distributive justice was thought to be a non-essential aspect of professionalism. In Western countries, physicians tend to promote justice in the health care system, including fair distribution of medical resources; however, we found that medical students in South Korea were more inclined to emphasize doctors' relationships with patients. Medical educators should develop curricular interventions regarding medical professionalism to meet the legitimate needs of patients in their own culture. Because professionalism is a dynamic construct of culture, medical educators should reaffirm cultural context-specific definitions of professionalism for development of associated curricula.

    International clinical placements provide undergraduate nursing students with the opportunity to experience or practice nursing care in diverse countries, settings, and cultures. This systematic review aims to ascertain the current knowledge on international clinical placements offered by undergraduate nursing programs in Australia. It seeks to explore three questions: (1) How have previous experiences of nursing students' international clinical placements been described? (2) How have participants and stakeholders determined if the placement has been successful? And (3) What benefits or challenges have been identified by stakeholders as a result of participating in international clinical placements? A systematic thematic synthesis was undertaken. A search of electronic databases including CINAHL, Proquest Central, Scopus, PubMed, and Health Collection was undertaken between September and October 2014. Key terms including 'international clinical placement', 'study abroad', 'international exchange', 'nursing', and 'Australia' were used to identify articles that appeared in peer-reviewed English language journals and that explored international clinical placements offered to undergraduate nursing students by Australian universities. Eight studies were identified that meet the inclusion criteria, and through thematic analysis, five key themes were identified including developing cultural awareness and competence, providing a global perspective on health care, translation of theory to practice, growing personally through reflection, and overcoming apprehension to successfully meet the challenge. A comparison search of literature from Canada and the United Kingdom revealed that similar themes occurred internationally. Although personal successes were identified by students undertaking international clinical placement, further research is required to identify all stakeholder experiences including those of the educators, the educational institutions, and travel providers

  11. The use of Latin terminology in medical case reports: quantitative, structural, and thematic analysis.

    This paper focuses on the prevalence of Latin terms and terminological collocations in the issues of Journal of Medical Case Reports (February 2007-August 2017) and discusses the role of Latin terminology in the contemporary process of writing medical case reports. The objective of the research is to study the frequency of using Latin terminology in English-language medical case reports, thus providing relevant guidelines for medical professionals who deal with this genre and drawing their attention to the peculiarities of using Latin in case reports. The selected medical case reports are considered, using methods of quantitative examination and structural, narrative, and contextual analyses. We developed structural and thematic typologies of Latin terms and expressions, and we conducted a quantitative analysis that enabled us to observe the tendencies in using these lexical units in medical case reports. The research revealed that the use of Latin fully complies with the communicative strategies of medical case reports as a genre. Owing to the fact that Latin medical lexis is internationally adopted and understood worldwide, it promotes the conciseness of medical case reports, as well as contributes to their narrative style and educational intentions. The adequate use of Latin terms in medical case reports is an essential prerequisite of effective sharing of one's clinical findings with fellow researchers from all over the world. Therefore, it is highly important to draw students' attention to Latin terms and expressions that are used in medical case reports most frequently. Hence, the analysis of structural, thematic, and contextual features of Latin terms in case reports should be an integral part of curricula at medical universities.

    2018-04-01

    To undertake a mixed methods thematic literature review that explored how elderly adults approached decision-making in regard to their health care following discharge. A critical time for appropriate health decisions occurs during hospital discharge planning with nursing staff. However, little is known how the 89% of elderly living at home make decisions regarding their health care. Research into older adults' management of chronic conditions emerges as an important step to potentially encourage symptom monitoring, prevent missed care and detect deterioration. All should reduce the risk of hospital re-admission. A mixed methods thematic literature review was undertaken. The structure followed the PRISMA reporting guidelines for systematic reviews recommended by the EQUATOR network. PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL) and Scopus online databases were searched using keywords, inclusion and exclusion criteria. References drawn from relevant publications, identified by experts and published between 1995 and 2017 were also considered. Twenty-five qualitative, quantitative and mixed methods studies and reviews were critically appraised (CASP 2013) before inclusion in the review. Analysis of each study's findings was undertaken using Braun and Clarke's (2006) steps to identify major themes and sub-themes. Four main themes associated with health-related decision-making in the elderly were identified: "the importance of maintaining independence," "decision making style," "management of conditions at home" and "discharge planning." Health care decision preferences in the elderly emerged as highly complex and influenced by multiple factors. Development of a tool to assess these components has been recommended. Nurses play a vital role in exploring and understanding the influence that maintaining independence has with each patient. This understanding provides an initial step toward development of a tool to assist collaboration between

  13. Creating the environment for driver distraction: A thematic framework of sociotechnical factors.

    2018-04-01

    As modern society becomes more reliant on technology, its use within the vehicle is becoming a concern for road safety due to both portable and built-in devices offering sources of distraction. While the effects of distracting technologies are well documented, little is known about the causal factors that lead to the drivers' engagement with technological devices. The relevance of the sociotechnical system within which the behaviour occurs requires further research. This paper presents two experiments, the first aims to assess the drivers self-reported decision to engage with technological tasks while driving and their reasoning for doing so with respect to the wider sociotechnical system. This utilised a semi-structured interview method, conducted with 30 drivers to initiate a discussion on their likelihood of engaging with 22 different tasks across 7 different road types. Inductive thematic analysis provided a hierarchical thematic framework that detailed the self-reported causal factors that influence the drivers' use of technology whilst driving. The second experiment assessed the relevance of the hierarchical framework to a model of distraction that was established from within the literature on the drivers use of distracting technologies while driving. The findings provide validation for some relationships studied in the literature, as well as providing insights into relationships that require further study. The role of the sociotechnical system in the engagement of distractions while driving is highlighted, with the causal factors reported by drivers suggesting the importance of considering the wider system within which the behaviour is occurring and how it may be creating the conditions for distraction to occur. This supports previous claims made within the literature based model. Recommendations are proposed that encourage a movement away from individual focused countermeasures towards systemic actors.

  14. A Thematic Look at Selected Cases of Marital Nullity in the Philippines

    Directory of Open Access Journals (Sweden)

    Antero Rosauro V. Arias, Jr.

    2018-05-01

    Full Text Available Psychological incapacity on the part of either or both spouses as the basis of marital nullity under Article 36 of The Family Code of the Philippines has long been traced to cases of personality disorders. From a theoretical framework that included the legal basis under the said article and the categorical model of the Diagnostic and Statistical Manual of Mental Disorders-IV-TR (DSM-IV-TR, the author purposefully selected several clinical cases of spouses’ narratives in their social case history – these narratives were already part and parcel of court transcripts. Employing a qualitative research methodology using thematic analysis, they were then dissected into superordinate themes that represented spouses’ developmental years, premarital relationship years, and period of marital cohabitation as husband and wife. Thereafter, other themes and possible subthemes were extracted and listed under each of these superordinate themes. These themes and subthemes were then equated to the spouses’ overt manifestations of psychological incapacity. In turn, these manifestations were matched with any or all of the diagnostic features or traits of personality functioning in the DSM. The ultimate objective of deriving and labelling the identified themes with specific personality disorders, with due consideration to the subthemes that referred to spouses’ juridical antecedent behaviors, was successfully achieved to supplement the use of powerful psychometric tests, including the use of projective techniques which were utilized in the local courts. This innovative scheme of thematically analyzing spouses’ narratives on marital nullification figured very well in forensic mental health assessment, especially when the respondent spouse was not available to undergo the necessary psychological assessment for some reason.

    Training in innovation and entrepreneurship (I&E) in medical education has become increasingly prevalent among medical schools to train students in complex problem solving and solution design. We aim to characterize I&E education in US allopathic medical schools to provide insight into the features and objectives of this growing field. I&E programs were identified in 2016 via structured searches of 158 US allopathic medical school websites. Program characteristics were identified from public program resources and structured phone interviews with program directors. Curricular themes were identified via thematic analysis of program resources, and themes referenced by >50% of programs were analyzed. Thirteen programs were identified. Programs had a median age of four years, and contained a median of 13 students. Programs were led by faculty from diverse professional backgrounds, and all awarded formal recognition to graduates. Nine programs spanned all four years of medical school and ten programs required a capstone project. Thematic analysis revealed seven educational themes (innovation, entrepreneurship, technology, leadership, healthcare systems, business of medicine, and enhanced adaptability) and two teaching method themes (active learning, interdisciplinary teaching) referenced by >50% of programs. The landscape of medical school I&E programs is rapidly expanding to address newfound skills needed by physicians due to ongoing changes in healthcare, but programs remain relatively few and small compared to class size. This landscape analysis is the first review of I&E in medical education and may contribute to development of a formal educational framework or competency model for current or future programs.

    A 2D land cover map can automatically and efficiently be generated from high-resolution multispectral aerial images. First, a digital surface model is produced and each cell of the elevation model is then supplemented with attributes. A decision tree classification is applied to extract map objects...... of stereo-observations of false-colour stereopairs. The stratified statistical assessment of the produced land cover map with six classes and based on 91 points per class reveals a high thematic accuracy for classes ‘building’ (99%, 95% CI: 95%-100%) and ‘road and parking lot’ (90%, 95% CI: 83%-95%).

    In this article, we describe and evaluate body mapping as (a) an arts-based activity within Fostering Open eXpression Among Youth (FOXY), an educational intervention targeting Northwest Territories (NWT) youth, and (b) a research data collection tool. Data included individual interviews with 41 female participants (aged 13-17 years) who attended FOXY body mapping workshops in six communities in 2013, field notes taken by the researcher during the workshops and interviews, and written reflections from seven FOXY facilitators on the body mapping process (from 2013 to 2016). Thematic analysis explored the utility of body mapping using a developmental evaluation methodology. The results show body mapping is an intervention tool that supports and encourages participant self-reflection, introspection, personal connectedness, and processing difficult emotions. Body mapping is also a data collection catalyst that enables trust and youth voice in research, reduces verbal communication barriers, and facilitates the collection of rich data regarding personal experiences.

    The present study examined the intersectionality of stigma across varying groups of older persons living with HIV (PWH). Four focus groups of older PWH (gay/bisexual men, heterosexual men, heterosexual and bisexualwomen, and Spanish-speaking) were audio-recorded and transcribed. Inductive thematic text analysis was used to identify qualitative themes. Five major themes emerged from the data: 1) disclosure of HIV status; 2) types of stigma experienced; 3) discrimination experienced; 4) other outcomes associated with experiencing stigma; and 5) influence of aging on social isolation experienced due to stigma. Findings indicate women did not suffer from the intersection of stigmas. Other groups suffered from the intersection of stigma due to HIV status and age (gay/bisexual males); HIV status and perceived stigma of sexual orientation or drug use (heterosexual males); and HIV status and culture/ethnicity (Spanish-speaking). Results indicate that many at-risk groups, including heterosexual men, homosexual men, and Spanish-speaking individuals, experience an intersection of stigma between aging and their sexuality, HIV status, or real or perceived drug use. Results highlight the need for HIV support, especially social support, to address intersection of stigmas for unique groups of individuals disproportionately affected by HIV.

  10. Blogs Written by Families During Their Child's Hospitalization: A Thematic Narrative Analysis.

    Jones, Carolyn W; Lynn, Mary R

    2018-04-04

    To identify stressors experienced by parents whose child is hospitalized in an intensive care unit, and identify coping mechanisms utilized to ameliorate those stressors. Using Lazarus and Folkman's Transactional Model of Stress and Coping as a framework, 20 publicly available blogs written by parents while their child was a patient in intensive care were analyzed using thematic analysis techniques. Stressors and coping techniques were identified, and grouped by theme for further analysis. The most frequently noted types of stressors were related to information; both knowing and not knowing information related to their child's condition was reported as stressful, as well as waiting for information and when the information was not what was expected. Reframing was the emotion-focused technique most often identified by the parents, and seeking support was the most frequently noted problem-focused coping mechanism. Illness blogs represent a rich source of information regarding the experiences of families with a child in the hospital. Parents transitioned from more emotion-focused coping strategies to problem-focused strategies during their child's hospital stay. When nurses give information to parents, they should be aware that knowing information can be stressful as well as not knowing, and care should be taken to provide support for parents after information is given. Nurses can also help parents identify sources of support. Writing about their experiences, either online or in a journal, may help parents cope in stressful situations. Copyright © 2017 Elsevier Inc.

    Baker, Felicity A.; Grocke, Denise; Berlowitz, David J.

    2014-01-01

    Background: People living with quadriplegia are at risk for social isolation and depression. Research with other marginalized groups has indicated that music therapy can have a positive effect on mood and social interaction. Objective: To gather descriptions of participants’ experience of 2 types of group music therapy – therapeutic singing or music appreciation and relaxation – and to determine commonalities and differences between participants’ experience of these 2 methods. Methods: We interviewed 20 people with quadriplegia about their experience of participating in 12 weeks of therapeutic singing (n = 10) or music appreciation and relaxation (n = 10). These methods of group music therapy were the interventions tested in a previously reported randomized controlled trial. The interview data were subjected to an inductive thematic analysis. Results: Six main themes were generated from the interview data. Four of these were shared themes and indicated that both types of group music therapy had a positive effect on mood/mental state and physical state, encouraged social engagement, and reconnected participants with their music identity or relationship with music. In addition, the participants who participated in the singing groups found singing to be challenging and confronting, but experienced a general increase in motivation. Conclusions: Group music therapy was experienced as an enjoyable and accessible activity that reconnected participants with their own music. Participants frequently described positive shifts in mood and energy levels, and social interaction was stimulated both within and beyond the music therapy groups. PMID:25484569

    2017-01-01

    Feline obesity has become a common disease and important animal welfare issue. Little is known about how, or how often, veterinarians and feline-owning clients are addressing obesity during clinical appointments. The purpose of this qualitative study was to characterize verbal and non-verbal communication between veterinarians and clients regarding feline obesity. The sample consisted of video-recordings of 17 veterinarians during 284 actual appointments in companion animal patients in Eastern Ontario. This audio-visual dataset served to identify 123 feline appointments. Of these, only 25 appointments were identified in which 12 veterinarians and their clients spoke about feline obesity. Thematic analysis of the videos and transcripts revealed inconsistencies in the depth of address of feline obesity and its prevention by participating veterinarians. In particular, in-depth nutritional history taking and clear recommendations of management rarely took place. Veterinarians appeared to attempt to strengthen the veterinary-client relationship and cope with ambiguity in their role managing obesity with humor and by speaking directly to their animal patients. Clients also appeared to use humor to deal with discomfort surrounding the topic. Our findings have implications for communication skills training within veterinary curricula and professional development among practicing veterinarians. As obesity is complex and potentially sensitive subject matter, we suggest a need for veterinarians to have further intentionality and training toward in-depth nutritional history gathering and information sharing while navigating obesity management discussions to more completely address client perspective and patient needs.

    1984-01-01

    A computer-implemented classification has been derived from Landsat-4 Thematic Mapper data acquired over Baldwin County, Alabama on January 15, 1983. One set of spectral signatures was developed from the data by utilizing a 3x3 pixel sliding window approach. An analysis of the classification produced from this technique identified forested areas. Additional information regarding only the forested areas. Additional information regarding only the forested areas was extracted by employing a pixel-by-pixel signature development program which derived spectral statistics only for pixels within the forested land covers. The spectral statistics from both approaches were integrated and the data classified. This classification was evaluated by comparing the spectral classes produced from the data against corresponding ground verification polygons. This iterative data analysis technique resulted in an overall classification accuracy of 88.4 percent correct for slash pine, young pine, loblolly pine, natural pine, and mixed hardwood-pine. An accuracy assessment matrix has been produced for the classification.

    The possibility of using Landsat Thematic Mapper (TM) thermal data to derive absolute temperature distributions in coastal waters that receive cooling effluent from a power plant is demonstrated. Landsat TM band 6 (thermal) data acquired on June 18, 1986, for the Diablo Canyon power plant in California were compared to ground truth temperatures measured at the same time. Higher-resolution band 5 (reflectance) data were used to locate power plant discharge and intake positions and identify locations of thermal pixels containing only water, no land. Local radiosonde measurements, used in LOWTRAN 6 adjustments for atmospheric effects, produced corrected ocean surface radiances that, when converted to temperatures, gave values within approximately 0.6 C of ground truth. A contour plot was produced that compared power plant plume temperatures with those of the ocean and coastal environment. It is concluded that Landsat can provide good estimates of absolute temperatures of the coastal power plant thermal plume. Moreover, quantitative information on ambient ocean surface temperature conditions (e.g., upwelling) may enhance interpretation of numerical model prediction.

    2015-06-01

    Psychoanalysts' written reports on initial consultations are a window into the complexities of a crucial aspect of psychoanalytic work. However, systematic research in this area has largely focused on patients' demographic factors or standardized measures. The present study looked at reports of all the consultations taking place at the London Clinic of Psychoanalysis over one calendar year (N = 100). The aim was to explore psychoanalysts' different explicit styles of working and reporting as well as further understanding implicit processes used in thinking and writing about each particular consultation experience. A thematic analysis revealed a set of themes that related to a style of working and thinking about the consultation process as a dyadic experience, where the interaction, affective reactions and contact made between the two are the focus when thinking of making a recommendation for psychoanalysis. The majority of the reports had an open, exploratory quality. The writing of reports appears to give the analyst an opportunity to process the consultation experience and arrive at a more triangular position. Writing reports is a more valuable part of the consultation process than has formally been recognized and acknowledged. The limitations of this study as well as the relevance of these findings for future research are discussed. Copyright © 2015 Institute of Psychoanalysis.

    2018-02-19

    The effective treatment of Borderline Personality Disorder (BPD) presents healthcare providers with a significant challenge. The evidence base remains limited partially due to a lack of professional consensus and service user involvement regarding ways of measuring change. As a result, the limited evidence that is available draws on such a wide range of outcome measures, that comparison across treatment types is hindered, maintaining a lack of clarity regarding the clinical needs of this group. This investigation aimed to follow the National Institute of Clinical Excellence (NICE, 2009) research recommendations by asking service users about meaningful change within their recovery. This forms a starting point for the future development of a tailored outcome measure. Fifteen service users with a diagnosis of BPD participated in three focus groups across two specialist Personality Disorder services. The focus groups were analysed using Thematic Analysis. Two superordinate themes were synthesized from the data: (1) recovery to what?: 'How do you rewrite who you are?'; and (2) conditions for change. Each superordinate theme further consisted of three subordinate themes which elucidated the over-arching themes. This investigation highlights the complex nature of measuring change in people who have received a BPD diagnosis. Further research is needed to develop meaningful ways of measuring change according to the needs and priorities of people with BPD.

    The first objective was to evaluate the postlaunch radiometric calibration of the LANDSAT Thematic Mapper (TM) band 6 data. The second objective was to determine to what extent surface temperatures could be computed from the TM and 6 data using atmospheric propagation models. To accomplish this, ground truth data were compared to a single TM-4 band 6 data set. This comparison indicated satisfactory agreement over a narrow temperature range. The atmospheric propagation model (modified LOWTRAN 5A) was used to predict surface temperature values based on the radiance at the spacecraft. The aircraft data were calibrated using a multi-altitude profile calibration technique which had been extensively tested in previous studies. This aircraft calibration permitted measurement of surface temperatures based on the radiance reaching the aircraft. When these temperature values are evaluated, an error in the satellite's ability to predict surface temperatures can be estimated. This study indicated that by carefully accounting for various sensor calibration and atmospheric propagation effects, and expected error (1 standard deviation) in surface temperature would be 0.9 K. This assumes no error in surface emissivity and no sampling error due to target location. These results indicate that the satellite calibration is within nominal limits to within this study's ability to measure error.

    An EC-funded thematic network was established to bring together experts in the field of thorium analysis in order to co-ordinate research activity and identify best analytical practice, requirements for reference materials, etc. The work programme of the network included (i) a survey of past, current and proposed research to determine future research needs; (ii) a series of intercomparison exercises to test the performance of methods for measuring thorium in workplace materials; and (iii) a workshop to promote best practice and transfer information to regulatory authorities and industry. Three interlaboratory comparisons were carried out, as planned, to test the performance of techniques and methodologies available for measurement of thorium. Test solutions containing 232 Th and 228 Th in equilibrium, test solutions containing 232 Th and 228 Th in disequilibrium and solid test samples containing 232 Th and 228 Th in equilibrium were supplied to participants. These were analysed by a variety of techniques. Full details of the three laboratory intercomparisons are given in a series of HSL reports and in other publications

    Mindfulness training, which teaches individuals to bring awareness and acceptance to the present moment, has been effective in improving the well-being of health care workers. Limited research examines the adoption of mindfulness practices using health behavior theories. The current study sought to conceptualize hospital health care workers' experiences in adopting mindfulness practices using the Health Belief Model (HBM), a theoretical framework used by health promotion practitioners to design and implement health behavior change interventions. Hospital health care workers in Colorado participated in an 8-week Mindfulness-Based Stress Reduction (MBSR) course. Participants ( n = 19) answered open-ended questions about their experiences adopting mindfulness practices. A theory-driven thematic analysis approach was used to analyze data with key constructs of the HBM acting as the framework for the analysis. Results showed that HBM constructs, including internal cues to action, perceived benefits and barriers, and self-efficacy, helped portray the participants' experiences and challenges in adopting and adhering to the mindfulness practices taught in the MBSR course.

    2017-11-03

    To explore the beliefs and attitudes of emergency department staff about self-harm behaviour. Existing studies looking at views regarding self-harm rely solely on the information provided by medical and nursing staff using a questionnaire format. No studies currently consider ancillary staff members' beliefs about self-harm, even though they also work with these patients. A thematic framework analysis of interview transcripts was carried out. Individual semi-structured interviews were conducted from December 2015 to February 2016. Fifteen medical, nursing, and ancillary staff members from a large, tertiary emergency department participated. There were 5 major themes identified-causes of self-harm are multifactorial; beliefs about self-harm can change over time; emergency departments should only focus on the physical; self-harm occurs on a spectrum; and the system has failed. The results suggest participants felt ill-prepared and lacking in appropriate training to help patients that self-harm, and furthermore they have little faith in the mental health system. Staff beliefs and attitudes may change over time with exposure to patients who self-harm, possibly becoming more positive in response to a greater understanding of why the self-harm behaviour is occurring.

    2008-05-01

    Extending the study of autobiographical narratives to entire life narratives, we tested the emergence of globally coherent life narratives in adolescence, as hypothesized by McAdams (1985). Participants were 102 children and young adults (ages 8, 12, 16, and 20 years) who narrated their lives twice. Between narrations, half of each age group participated in tasks designed to train autobiographical reasoning; the other half participated in control tasks. Coherence was measured by the relative frequency of local temporal, causal, and thematic linguistic indicators identified qualitatively at the level of propositions, as well as by quantitative global rating scales measuring the impressions of the listeners. Coherence increased across the age span. Overall, repeated narrating and training did not increase coherence. Crystallized and fluid intelligence, number of negative life events, and frequency of biographical practices and confiding in others did not contribute substantially to the prediction of coherence beyond age. Results are interpreted in the context of adolescent identity development. (PsycINFO Database Record (c) 2008 APA, all rights reserved).

    This study describes the learning effects of thematic peer-review discussion groups (Hendriksen, 2000. Begeleid intervisie model, Collegiale advisering en probleemoplossing, Nelissen, Baarn.) on developing nursing students' competence in providing spiritual care. It also discusses the factors that might influence the learning process. The method of peer-review is a form of reflective learning based on the theory of experiential learning (Kolb, 1984. Experiential learning, Experience as the source of learning development. Englewoods Cliffs, New Jersey, Prentice Hill). It was part of an educational programme on spiritual care in nursing for third-year undergraduate nursing students from two nursing schools in the Netherlands. Reflective journals (n=203) kept by students throughout the peer-review process were analysed qualitatively The analysis shows that students reflect on spirituality in the context of personal experiences in nursing practice. In addition, they discuss the nursing process and organizational aspects of spiritual care. The results show that the first two phases in the experiential learning cycle appear prominently; these are 'inclusion of actual experience' and 'reflecting on this experience'. The phases of 'abstraction of experience' and 'experimenting with new behaviour' are less evident. We will discuss possible explanations for these findings according to factors related to education, the students and the tutors and make recommendations for follow-up research.

    A "quick look" investigation of the initial LANDSAT-4, thematic mapper (TM) scene received from Goddard Space Flight Center was performed to gain early insight into the characteristics of TM data. The initial scene, containing only the first four bands of the seven bands recorded by the TM, was acquired over the Detroit, Michigan, area on July 20, 1982. It yielded abundant information for scientific investigation. A wide variety of studies were conducted to assess all aspects of TM data. They ranged from manual analyses of image products to detect obvious optical, electronic, or mechanical defects to detailed machine analyses of the digital data content for evaluation of spectral separability of vegetative/nonvegetative classes. These studies were applied to several segments extracted from the full scene. No attempt was made to perform end-to-end statistical evaluations. However, the output of these studies do identify a degree of positive performance from the TM and its potential for advancing state-of-the-art crop inventory and condition assessment technology.

    Chapman, A L; Hadfield, M; Chapman, C J

    2015-01-01

    In today's NHS, qualitative research is increasingly important as a method of assessing and improving quality of care. Grounded theory has developed as an analytical approach to qualitative data over the last 40 years. It is primarily an inductive process whereby theoretical insights are generated from data, in contrast to deductive research where theoretical hypotheses are tested via data collection. Grounded theory has been one of the main contributors to the acceptance of qualitative methods in a wide range of applied social sciences. The influence of grounded theory as an approach is, in part, based on its provision of an explicit framework for analysis and theory generation. Furthermore the stress upon grounding research in the reality of participants has also given it credence in healthcare research. As with all analytical approaches, grounded theory has drawbacks and limitations. It is important to have an understanding of these in order to assess the applicability of this approach to healthcare research. In this review we outline the principles of grounded theory, and focus on thematic analysis as the analytical approach used most frequently in grounded theory studies, with the aim of providing clinicians with the skills to critically review studies using this methodology.

    1983-01-01

    The total and diffuse radiance responses of Thematic Mapper bands 3 (0.63-0.69 microns), 4 (0.76-0.90 microns), and 5 (1.55-1.75 microns) to water stress in a soybean canopy are compared. Polarization measurements were used to separate the total from the diffuse reflectance; the reflectances were compared statistically at a variety of look angles at 15 min intervals from about 09.00 until 14.00 hrs EST. The results suggest that remotely sensed data collected in the photographic infrared region (TM4) are sensitive to leaf water stress in a 100 percent canopy cover of soybeans, and that TM3 is less sensitive than TM4 for detection of reversible foliar water stress. The mean values of TM5 reflectance data show similar trends to TM4. The primary implication of this study is that remote sensing of water stress in green plant canopies is possible in TM4 from ground-based observations primarily through the indirect link of leaf geometry.

    Despite the pervasive social endorsement of "cheat meals" within pro-muscularity online communities, there is an absence of empirical work examining this dietary phenomenon. The present study aimed to characterize cheat meals, and explore the meaning ascribed to engagement in this practice. Thematic content analysis was employed to code the photographic and textual elements of a sample (n = 600) that was extracted from over 1.6 million images marked with the #cheatmeal tag on the social networking site, Instagram. Analysis of the volume and type of food revealed the presence of very large quantities (54.5%) of calorie-dense foods (71.3%) that was rated to qualify as an objective binge episode. Photographic content of people commonly portrayed highly-muscular bodies (60.7%) in the act of intentional body exposure (40.0%). Meanwhile, textual content exemplified the idealization of overconsumption, a strict commitment to fitness, and a reward-based framework around diet and fitness. Collectively, these findings position cheat meals as goal-oriented dietary practices in the pursuit of physique-ideals, thus underscoring the potential clinical repercussions of this socially-endorsed dietary phenomenon. © 2017 Wiley Periodicals, Inc.

  8. Ethical aspects in tissue research: thematic analysis of ethical statements to the research ethics committee

    Science.gov (United States)

    2012-01-01

    Background Many studies have been published about ethics committees and the clarifications requested about the submitted applications. In Finland, ethics committees require a separate statement on ethical aspects of the research in applications to the ethics committee. However, little is known about how researchers consider the ethical aspects of their own studies. Methods The data were collected from all the applications received by the official regional ethics committee in the Hospital District of Northern Savo during 2004–2009 (n = 688). These included a total of 56 studies involving research on tissue other than blood. The statements by the researchers about the ethics about their own research in these applications were analyzed by thematic content analysis under the following themes: recruitment, informed consent, risks and benefits, confidentiality and societal meaning. Results The researchers tended to describe recruitment and informed consent process very briefly. Usually these descriptions simply stated who the recruiter was and that written consent would be required. There was little information provided on the recruitment situation and on how the study recruiters would be informed. Although most of the studies were clinical, the possibility was hardly ever discussed that patients could fail to distinguish between care and research. Conclusion The written guidelines, available on the webpages of the ethics committee, do not seem to be enough to help researchers achieve this goal. In addition to detailed guidelines for researchers, investigators need to be taught to appreciate the ethical aspects in their own studies. PMID:22873761

    Medicines non-adherence continues to be problematic in health care practice. After decades of research, few interventions have a robust evidence-based demonstrating their applicability to improve adherence. Phenomenology has a place within the health care research environment. To explore patients' lived experiences of medicines adherence reported in the phenomenonologic literature. A systematic literature search was conducted to identify peer-reviewed and published phenomenological investigations in adults that aimed to investigate patients' lived experiences of medicines adherence. Studies were appraised using the Critical Appraisal Skills Programme (CASP) Qualitative Research Tool. Thematic synthesis was conducted using a combination of manual coding and NVivo10 [QSR International, Melbourne] coding to aid data management. Descriptive themes identified included i) dislike for medicines, ii) survival, iii) perceived need, including a) symptoms and side-effects and b) cost, and iv) routine. Analytic themes identified were i) identity and ii) interaction. This work describes adherence as a social interaction between the identity of patients and medicines, mediated by interaction with family, friends, health care professionals, the media and the medicine, itself. Health care professionals and policy makers should seek to re-locate adherence as a social phenomenon, directing the development of interventions to exploit patient interaction with wider society, such that patients 'get to know' their medicines, and how they can be taken, throughout the life of the patient and the prescription.

    This thematic series contains 4 papers mostly presented at the 2016 AOGS meeting in Beijing. The four papers investigate four key regions in the magnetosphere-ionosphere coupling process: mid-tail magnetosphere, near-Earth magnetosphere, inner magnetosphere, and the polar ground region. Guo et al. (Geosci Lett 4:18, 2017) study the current system in reconnection region using 2.5D particle-in-cell simulations. Yao et al. (Geosci Lett 4:8, 2017) use conjugate measurements from ground auroral imagers and in situ THEMIS spacecraft to reveal the mechanism for the wave-like auroral structures prior to substorm onset. Zhang et al. (Geosci Lett 4:20, 2017) investigate the profiles of resonance zone and resonant frequency in the Landau resonance between radiation belt electrons and magnetosonic waves and between protons and cyclotron waves. Rae et al. (Geosci Lett 4:23, 2017) determine the relative timing between sudden increases in amplitude, or onsets, of different ultra-low-frequency wave bands during substorms.

    Since 1 April 2013, local authority (LA) health and well-being boards (HWBs) in England are required to publish a health and well-being strategy (HWS). HWSs should identify how population health needs are to be addressed. The extent to which this has been achieved is not known. We analysed HWSs to assess how LAs have interpreted statutory guidance, how evidence has been used within HWSs and the relationship of HWSs to Joint Strategic Needs Assessments (JSNAs). Qualitative thematic content analysis of a random sample of one-third of upper tier LA HWSs in 2013-14. Fifty out of 152 LAs were sampled and 47 HWSs analysed. Strategies varied in timescale, length and structure. The term 'evidence' was used most commonly referring to local need, rather than evidence of effectiveness. All, except two, referred to JSNAs. HWSs are dominated by evidence of need and could be strengthened by greater use of evidence of effectiveness for public health interventions. Public health agencies and academics can support the development of effective HWSs by improving the accessibility of evidence and conducting research when evidence is absent. To strengthen HWSs' impact, the statutory guidance should clarify the distinction between evidence of need and evidence of effectiveness. © The Author 2014.

    Smartphone and mobile application technology have in recent years furthered the development of novel learning and assessment resources. 'MBChB Mobile' is a pioneering mobile learning (M-Learning) programme at University of Leeds, United Kingdom and provides all senior medical students with iPhone handsets complete with academic applications, assessment software and a virtual reflective environment. This study aimed to evaluate the impact of MBChB Mobile on student learning. Ethical approval was granted to invite fourth and fifth year medical students to participate in a semi-quantitative questionnaire: data were collected anonymously with informed consent and analysed where appropriate using chi-squared test of association. Qualitative data generated through focus group participation were subjected to both content and thematic analysis. A total of 278 of 519 (53.6%) invited participants responded. Overall, 72.6% of students agreed that MBChB Mobile enhanced their learning experience; however, this was significantly related to overall usage (P mobile technology proficiency (P mobile devices, and perceived patient acceptability. As one of the largest evaluative and only quantitative study of smartphone-assisted M-Learning in undergraduate medical education, MBChB Mobile suggests that smartphone and application technology enhances students' learning experience. Barriers to implementation may be addressed through the provision of tailored learning resources, along with user-defined support systems, and appropriate means of ensuring acceptability to patients. © 2015 John Wiley & Sons, Ltd.

    2003-04-01

    The Annual Statistics of Medical School Libraries in the United States and Canada (Annual Statistics) is the most recognizable achievement of the Association of Academic Health Sciences Libraries in its history to date. This article gives a thematic history of the Annual Statistics, emphasizing the leadership role of editors and Editorial Boards, the need for cooperation and membership support to produce comparable data useful for everyday management of academic medical center libraries and the use of technology as a tool for data gathering and publication. The Annual Statistics' origin is recalled, and survey features and content are related to the overall themes. The success of the Annual Statistics is evident in the leadership skills of the first editor, Richard Lyders, executive director of the Houston Academy of Medicine-Texas Medical Center Library. The history shows the development of a survey instrument that strives to produce reliable and valid data for a diverse group of libraries while reflecting the many complex changes in the library environment. The future of the Annual Statistics is assured by the anticipated changes facing academic health sciences libraries, namely the need to reflect the transition from a physical environment to an electronic operation.

    Full Text Available Abstract Bracing is the main non-surgical intervention in the treatment of idiopathic scoliosis during growth, in hyperkyphosis (and Scheuermann disease and occasionally for spondylolisthesis; it can be used in adult scoliosis, in the elderly when pathological curves lead to a forward leaning posture or in adults after traumatic injuries. Bracing can be defined as the application of external corrective forces to the trunk; rigid supports or elastic bands can be used and braces can be custom-made or prefabricated. The state of research in the field of conservative treatment is insufficient and while it can be stated that there is some evidence to support bracing, we must also acknowledge that today we do not have a common and generally accepted knowledge base, and that instead, individual expertise still prevails, giving rise to different schools of thought on brace construction and principles of correction. The only way to improve the knowledge and understanding of brace type and brace function is to establish a single and comprehensive source of information about bracing. This is what the Scoliosis Journal is going to do through the "Brace Technology" Thematic Series, where technical papers coming from the different schools will be published.

    Full Text Available The Arctic is warming and losing sea ice. Happening at a much faster rate than previously expected, these changes are causing multiple ecosystem feedbacks in the Arctic Ocean. The Arctic in Rapid Transition (ART initiative was developed by early-career scientists as an integrative, international, multidisciplinary, long-term pan-Arctic network to study changes and feedbacks among the physical and biogeochemical components of the Arctic Ocean and their ultimate impacts on biological productivity on different timescales. In 2012, ART jointly organized with the Association of Polar Early Career Scientists their second science workshop—Overcoming Challenges of Observation to Model Integration in Marine Ecosystem Response to Sea Ice Transitions—at the Institute of Oceanology, Polish Academy of Sciences, in Sopot. This workshop aimed to identify linkages and feedbacks between atmosphere–ice–ocean forcing and biogeochemical processes, which are critical for ecosystem function, land–ocean interactions and productive capacity of the Arctic Ocean. This special thematic cluster of Polar Research brings together seven papers that grew out of workgroup discussions. Papers examine the climate change impacts on various ecosystem elements, providing important insights on the marine ecological and biogeochemical processes on various timescales. They also highlight priority areas for future research.

  16. Detection of soil erosion within pinyon-juniper woodlands using Thematic Mapper (TM) data

    Price, Kevin P.

    1993-01-01

    Multispectral measurements collected by Landsat Thematic Mapper (TM) were correlated with field measurements, direct soil loss estimates, and Universal Soil Loss Equation (USLE) estimates to determine the sensitivity of TM data to varying degrees of soil erosion in pinyon-juniper woodland in central Utah. TM data were also evaluated as a predictor of the USLE Crop Management C factor for pinyon-juniper woodlands. TM spectral data were consistently better predictors of soil erosion factors than any combination of field factors. TM data were more sensitive to vegetation variations than the USLE C factor. USLE estimates showed low annual rates of erosion which varied little among the study sites. Direct measurements of rate of soil loss using the SEDIMENT (Soil Erosion DIrect measureMENT) technique, indicated high and varying rates of soil loss among the sites since tree establishment. Erosion estimates from the USLE and SEDIMENT methods suggest that erosion rates have been severe in the past, but because significant amounts of soil have already been eroded, and the surface is now armored by rock debris, present erosion rates are lower. Indicators of accelerated erosion were still present on all sites, however, suggesting that the USLE underestimated erosion within the study area.

    2017-04-01

    Participation in the labour force with a hearing impairment presents a number of challenges. This study describes how Canadian newspapers represent workers with hearing loss. Taking a critical framing theory approach, thematic analysis was performed through coding relevant articles, abstracting and hierarchically categorising themes. Seven English-language Canadian newspapers were searched for publications between 1995 and 2016. Twenty-six articles met our criteria: discussing paid workers with hearing loss who used English rather than sign language on the job and making reference to workers' competence. We identified a global theme, Focussing on a good worklife or focussing on a limited worklife, composed of three organising themes (1) Prominent individuals struggle, take action, and continue despite hearing loss, (2) Workers with hearing loss in the community create their best day themselves, and (3) Workers with hearing loss, as a generalised whole, are portrayed as either competent or limited. The dominant framing portrays individual workers as ingenious, determined, and successful. Negative framings were predominantly generalisations to these workers as a group. To generate more positive framings, professionals can build relationships with consumer groups and, when contacted by the media, direct journalists to interview workers with hearing loss.

  18. An exploration of person-centred concepts in human services: A thematic analysis of the literature.

    Waters, Rebecca A; Buchanan, Angus

    2017-10-01

    Being 'person-centred' in the delivery of health and human services has become synonymous with quality care, and it is a core feature of policy reform in Australia and other Western countries. This research aimed to identify the uses, definitions and characteristics of the term 'person-centred' in the ageing, mental health and disability literature. A thematic analysis identified seven common core themes of person-centredness: honouring the person, being in relationship, facilitating participation and engagement, social inclusion/citizenship, experiencing compassionate love, being strengths/capacity focussed, and organisational characteristics. These suggest a set of higher-order experiences for people that are translated differently in different human services. There is no common definition of what it means to be person-centred, despite being a core feature of contemporary health and human service policy, and this suggests that its inclusion facilitates further misunderstanding and misinterpretation. A common understanding and policy conceptualisation of person-centredness is likely to support quality outcomes in service delivery especially where organisations work across human service groups. Further research into the application and service expressions of being 'person-centred' in context is necessary. Copyright © 2017 Elsevier B.V. All rights reserved.

  19. A Thematic Analysis of Career Adaptability in Retirees Who Return to Work.

    Luke, Jennifer; McIlveen, Peter; Perera, Harsha N

    2016-01-01

    Retirement can no longer be conceptualized as disengagement, as the end of a person's career, as it is in the life-span, life-space theory. Increasingly, retirees are returning to work, in paid, and unpaid positions, in a part-time or full-time capacity, as an act of re-engagement. Vocational psychology theories are yet to adequately conceptualize the phenomenon of retirees' re-engagement in work. The research reported in this paper is the first attempt to understand re-engagement through the theoretical lens of career construction theory (CCT) and its central construct, career adaptability. The study involved intensive interviews with 22 retirees between the ages of 56 and 78 years (M = 68.24), who had retired no less than 1 year prior to the study. Participants were engaged in a discussion about their reasons for returning to the world of work. Thematic analysis of interview transcripts extracted evidence of the four career adaptability resources: concern, control, curiosity, and confidence. In addition, the influence of family and making a contribution were discerned as important themes. These findings are the first evidence that the CCT and career adaptability provide a new conceptual lens to theorize and conduct research into the phenomenon of retirement.

  20. Feline Obesity in Veterinary Medicine: Insights from a Thematic Analysis of Communication in Practice

    Directory of Open Access Journals (Sweden)

    Alexandra M. Phillips

    2017-07-01

    Full Text Available Feline obesity has become a common disease and important animal welfare issue. Little is known about how, or how often, veterinarians and feline-owning clients are addressing obesity during clinical appointments. The purpose of this qualitative study was to characterize verbal and non-verbal communication between veterinarians and clients regarding feline obesity. The sample consisted of video-recordings of 17 veterinarians during 284 actual appointments in companion animal patients in Eastern Ontario. This audio-visual dataset served to identify 123 feline appointments. Of these, only 25 appointments were identified in which 12 veterinarians and their clients spoke about feline obesity. Thematic analysis of the videos and transcripts revealed inconsistencies in the depth of address of feline obesity and its prevention by participating veterinarians. In particular, in-depth nutritional history taking and clear recommendations of management rarely took place. Veterinarians appeared to attempt to strengthen the veterinary–client relationship and cope with ambiguity in their role managing obesity with humor and by speaking directly to their animal patients. Clients also appeared to use humor to deal with discomfort surrounding the topic. Our findings have implications for communication skills training within veterinary curricula and professional development among practicing veterinarians. As obesity is complex and potentially sensitive subject matter, we suggest a need for veterinarians to have further intentionality and training toward in-depth nutritional history gathering and information sharing while navigating obesity management discussions to more completely address client perspective and patient needs.

    Full Text Available Since different pedologists will draw different soil maps of a same area, it is important to compare the differences between mapping by specialists and mapping techniques, as for example currently intensively discussed Digital Soil Mapping. Four detailed soil maps (scale 1:10.000 of a 182-ha sugarcane farm in the county of Rafard, São Paulo State, Brazil, were compared. The area has a large variation of soil formation factors. The maps were drawn independently by four soil scientists and compared with a fifth map obtained by a digital soil mapping technique. All pedologists were given the same set of information. As many field expeditions and soil pits as required by each surveyor were provided to define the mapping units (MUs. For the Digital Soil Map (DSM, spectral data were extracted from Landsat 5 Thematic Mapper (TM imagery as well as six terrain attributes from the topographic map of the area. These data were summarized by principal component analysis to generate the map designs of groups through Fuzzy K-means clustering. Field observations were made to identify the soils in the MUs and classify them according to the Brazilian Soil Classification System (BSCS. To compare the conventional and digital (DSM soil maps, they were crossed pairwise to generate confusion matrices that were mapped. The categorical analysis at each classification level of the BSCS showed that the agreement between the maps decreased towards the lower levels of classification and the great influence of the surveyor on both the mapping and definition of MUs in the soil map. The average correspondence between the conventional and DSM maps was similar. Therefore, the method used to obtain the DSM yielded similar results to those obtained by the conventional technique, while providing additional information about the landscape of each soil, useful for applications in future surveys of similar areas.

    1989-01-01

    A number of aspects to vulnerability maps are discussed: the vulnerability concept, mapping purposes, possible users, and applicability of vulnerability maps. Problems associated with general-type vulnerability mapping, including large-scale maps, universal pollutant, and universal pollution scenario are also discussed. An alternative approach to vulnerability assessment - specific vulnerability mapping for limited areas, specific pollutant, and predefined pollution scenario - is suggested. A simplification of the vulnerability concept is proposed in order to make vulnerability mapping more objective and by this means more comparable. An extension of the vulnerability concept to the rest of the hydrogeological cycle (lakes, rivers, and the sea) is proposed. Some recommendations regarding future activities are given

    1988-06-01

    Mapping techniques may be thought to be attractive for the long term prediction of motion in accelerators, especially because a simple map can approximately represent an arbitrarily complicated lattice. The intention of this paper is to develop prejudices as to the validity of such methods by applying them to a simple, exactly solveable, example. It is shown that a numerical interpolation map, such as can be generated in the accelerator tracking program TEAPOT, predicts the evolution more accurately than an analytically derived differential map of the same order. Even so, in the presence of ''appreciable'' nonlinearity, it is shown to be impractical to achieve ''accurate'' prediction beyond some hundreds of cycles of oscillation. This suggests that the value of nonlinear maps is restricted to the parameterization of only the ''leading'' deviation from linearity. 41 refs., 6 figs

  10. Exploring the potential offered by legacy soil databases for ecosystem services mapping of Central African soils

    Science.gov (United States)

    Verdoodt, Ann; Baert, Geert; Van Ranst, Eric

    2014-05-01

    Central African soil resources are characterised by a large variability, ranging from stony, shallow or sandy soils with poor life-sustaining capabilities to highly weathered soils that recycle and support large amounts of biomass. Socio-economic drivers within this largely rural region foster inappropriate land use and management, threaten soil quality and finally culminate into a declining soil productivity and increasing food insecurity. For the development of sustainable land use strategies targeting development planning and natural hazard mitigation, decision makers often rely on legacy soil maps and soil profile databases. Recent development cooperation financed projects led to the design of soil information systems for Rwanda, D.R. Congo, and (ongoing) Burundi. A major challenge is to exploit these existing soil databases and convert them into soil inference systems through an optimal combination of digital soil mapping techniques, land evaluation tools, and biogeochemical models. This presentation aims at (1) highlighting some key characteristics of typical Central African soils, (2) assessing the positional, geographic and semantic quality of the soil information systems, and (3) revealing its potential impacts on the use of these datasets for thematic mapping of soil ecosystem services (e.g. organic carbon storage, pH buffering capacity). Soil map quality is assessed considering positional and semantic quality, as well as geographic completeness. Descriptive statistics, decision tree classification and linear regression techniques are used to mine the soil profile databases. Geo-matching as well as class-matching approaches are considered when developing thematic maps. Variability in inherent as well as dynamic soil properties within the soil taxonomic units is highlighted. It is hypothesized that within-unit variation in soil properties highly affects the use and interpretation of thematic maps for ecosystem services mapping. Results will mainly be based

    2016-04-01

    The mission of EPOS is to monitor and understand the dynamic and complex Earth system by relying on new e-science opportunities and integrating diverse and advanced Research Infrastructures in Europe for solid Earth Science. EPOS will enable innovative multidisciplinary research for a better understanding of the Earth's physical and chemical processes that control earthquakes, volcanic eruptions, ground instability and tsunami as well as the processes driving tectonics and Earth's surface dynamics. Through integration of data, models and facilities EPOS will allow the Earth Science community to make a step change in developing new concepts and tools for key answers to scientific and socio-economic questions concerning geo-hazards and geo-resources as well as Earth sciences applications to the environment and to human welfare. EPOS, during its Implementation Phase (EPOS-IP), will integrate multidisciplinary data into a single e-infrastructure. Multidisciplinary data are organized and governed by the Thematic Core Services (TCS) and are driven by various scientific communities encompassing a wide spectrum of Earth science disciplines. These include Data, Data-products, Services and Software (DDSS), from seismology, near fault observatories, geodetic observations, volcano observations, satellite observations, geomagnetic observations, as well as data from various anthropogenic hazard episodes, geological information and modelling. In addition, transnational access to multi-scale laboratories and geo-energy test-beds for low-carbon energy will be provided. TCS DDSS will be integrated into Integrated Core Services (ICS), a platform that will ensure their interoperability and access to these services by the scientific community as well as other users within the society. This requires dedicated tasks for interactions with the various TCS-WPs, as well as the various distributed ICS (ICS-Ds), such as High Performance Computing (HPC) facilities, large scale data storage

This integration requires a significant coordination between, among others, disciplinary (thematic) communities, national RIs policies and initiatives, as well as geo- and IT-scientists. The RIs that EPOS is coordinating include: i) regionally-distributed geophysical observing systems (seismological and geodetic networks); ii) local observatories (including geomagnetic, near-fault and volcano observatories); iii) analytical and experimental laboratories; iv) integrated satellite data and geological information services v) new services for natural and anthropogenic hazards. Here we present the successful story of the EPOS Preparatory Phase and the progress towards the implementation of both integrated core services (ICS) and thematic core services (TCS) for the different communities participating to the integration plan. We aim to discuss the achieved results and the approach followed to design the implementation phase. The goal is to present and discuss the strategies adopted to foster the implementation of TCS, clarifying their crucial role as domain-specific service hubs for coordinating and harmonizing national resources/plans with the European dimension of EPOS, and their integration to develop the new ICS. We will present the prototype of the ICS central hub as a key contribution for providing multidisciplinary services for solid Earth sciences as well as the glue to keep ICT aspects integrated and rationalized across EPOS. Finally, we will discuss the well-defined role of the EPOS-ERIC Headquarter to coordinate and harmonize national RIs and EPOS services (through ICS and TCS) looking for an effective commitment by national governments. It will be an important and timely opportunity to discuss the EPOS roadmap toward the operation of the novel multidisciplinary platform for discoveries to foster scientific excellence in solid Earth sciences.

  13. Expanding Thurston maps

    CERN Document Server

    Bonk, Mario

    2017-01-01

    This monograph is devoted to the study of the dynamics of expanding Thurston maps under iteration. A Thurston map is a branched covering map on a two-dimensional topological sphere such that each critical point of the map has a finite orbit under iteration. It is called expanding if, roughly speaking, preimages of a fine open cover of the underlying sphere under iterates of the map become finer and finer as the order of the iterate increases. Every expanding Thurston map gives rise to a fractal space, called its visual sphere. Many dynamical properties of the map are encoded in the geometry of this visual sphere. For example, an expanding Thurston map is topologically conjugate to a rational map if and only if its visual sphere is quasisymmetrically equivalent to the Riemann sphere. This relation between dynamics and fractal geometry is the main focus for the investigations in this work.

    The surveyors in hospital accreditation program are considered as the core of accreditation programs. So, the reliability and validity of the accreditation program heavily depend on their performance. This study aimed to identify the dimensions and factors affecting surveyor management of hospital accreditation programs in Iran. This qualitative study used a thematic analysis method, and was performed in Iran in 2014. The study participants included experts in the field of hospital accreditation, and were derived from three groups: 1. Policy-makers, administrators, and surveyors of the accreditation bureau, the ministry of health and medical education, Iranian universities of medical science; 2. Healthcare service providers, and 3. University professors and faculty members. The data were collected using semi-structured in-depth interviews. Following text transcription and control of compliance with the original text, MAXQDA10 software was used to code, classify, and organize the interviews in six stages. The findings from the analysis of 21 interviews were first classified in the form of 1347 semantic units, 11 themes, 17 sub-themes, and 248 codes. These were further discussed by an expert panel, which then resulted in the emergence of seven main themes - selection and recruitment of the surveyor team, organization of the surveyor team, planning to perform surveys, surveyor motivation and retention, surveyor training, surveyor assessment, and recommendations - as well as 27 sub-themes, and 112 codes. The dimensions and variables affecting the surveyors' management were identified and classified on the basis of existing scientific methods in the form of a conceptual framework. Using the results of this study, it would certainly be possible to take a great step toward enhancing the reliability of surveys and the quality and safety of services, while effectively managing accreditation program surveyors.

We used a qualitative explorative design with semi-structured in-depth interviews. Twenty participants with TBI were included from a level I Trauma Center in Denmark at 1-4 years post-injury. Qualitative thematic analysis was applied for data analysis. Three main themes emerged during analysis: A new life, Family involvement, and Rehabilitation impediments. These themes and their sub-themes described the patient perspective of TBI and rehabilitation post hospitalization. Participants reassessed their values and found a new life after TBI. Family caregivers negotiated rehabilitation services and helped the participant to overcome barriers to rehabilitation. Although participants were entitled to TBI rehabilitation, they had to fight for the services they were entitled to. Individuals with TBI found ways of coping after injury and created a meaningful life. Barriers to TBI rehabilitation were overcome with help from family caregivers rather than health care professionals. Future studies need to find ways to ease the burden on family caregivers and pave the way for more accessible rehabilitation in this vulnerable group of patients. Implications for rehabilitation TBI rehabilitation might benefit from:    • Increased transparency in rehabilitation options    • More systematic follow-up programs    • Age-appropriate rehabilitation facilities    • Inclusion of patient and family in the planning of long-term rehabilitation.

    The aim of this study was to explore the work-life narratives of nurses through a thematic analysis of the nursing accounts they post in their publicly accessible, anonymous blogs. Many nurses participate on social media. Blogs have been advocated as a self-reflective tool in nursing practice, yet as far as the authors are aware, no previous studies have explored nurses' individual blogs for their potential to reveal nurses' perceptions of nursing work. The research design was qualitative description. Between May-August 2015, Internet search engines were used to discover lists of nursing blogs recommended by organizations representing nurses' interests. Recommended blogs were purposively sampled. Four anonymous blogs written by nurses from different nursing specialties met the sampling criteria. All 520 of their entries from 2014 were read and copied into NVivo 10, where an inductive coding process was followed. Three major themes arose in these nurses' online discussions of their work lives: they truly care about and value their nursing work, but they are feeling stressed and burnt out and they are using their anonymous blogs to share factors that frustrate them in their nursing work. Three main areas of frustration were revealed: teamwork problems, challenging patients and families, and management issues. Anonymous nursing blogs offer valuable, longitudinal insights into nurses' perceptions of their work lives. Nursing blogs should be further explored for ongoing insights into nurses' experiences of nursing work, as well as nurses' recommendations for addressing issues causing them to feel frustrated in their work environments. © 2017 John Wiley & Sons Ltd.

    Qualitative studies examining lived experiences of psychogenic nonepileptic seizures (PNES) have predominantly relied on datasets collected using clinical or research interviews. This study pursued a different approach by investigating individuals' written accounts of their condition. Participants (n=19) were recruited from membership-led organisations for individuals living with seizures and from a United Kingdom hospital. Participants were instructed to produce four pieces of writing: 1) about their thoughts and feelings about their condition; 2) a letter to their condition; 3) a letter to their younger self; and 4) about a personal value. All writings were analysed using thematic analysis. Six main-themes emerged from the data. Theme 1: 'living with PNES' demonstrated that all participants presented the condition as having a debilitating effect. Theme 2: 'Emotions' revealed that individuals were struggling with anxiety, low mood and self-worth. Theme 3: 'Seizure symptoms' showed variability was a prominent feature in the description of ictal events. Theme 4: 'Treatment and outcomes' demonstrated that individual's perception of diagnosis and therapy differed greatly. Theme 5: 'Causation and development' revealed that the majority of participants spontaneously reported experiencing a traumatic event in the past. Theme 6: 'Lack of understanding' by themselves, the public and healthcare professionals appeared to pose considerable challenges to participants. Qualitative research has an important role to play for improving our understanding of PNES. The findings contribute to the literature by highlighting the nature of stigma that people with PNES experience, and also their proneness to demonstrate problems with self-worth.

    The aim of this reflective account is to provide a view of the intensive care unit (ICU) relative's experiences of supporting and being supported in the ICU. Understanding the relatives' experiences of ICU is important especially because a recent work has identified the potential for this group to develop post-traumatic stress disorder, a condition that is normally equated with the ICU survivor. A thematic analysis was used in identifying emerging themes that would be significant in an ICU nursing context. The incident took place in two 8-bedded ICUs (Private and National Health Service) in October. Two emergent themes were identified from the reflective story - fear of the technological environment and feeling hopeless and helpless. The use of relative stories as an insight into the live experiences of ICU relatives may give a deeper understanding of their life-world. The loneliness, anguish and pain of the ICU relative extends beyond the walls of the ICU, and this is often negated as the focus of the ICU team is the patient. Developing strategies to support relatives might include the use of relative diaries used concurrently with patient diaries to support this groups recovery or at the very least a gaining a sense of understanding for their ICU experience. Relative follow-up clinics designed specifically to meet their needs where support and advice can be given by the ICU team, in addition to making timely and appropriate referrals to counselling services and perhaps involving spiritual leaders where appropriate. © 2014 British Association of Critical Care Nurses.

    Research purpose: This article draws on research suggesting that interactions between industry-sector (situational differences and cognitive biases may often be decisive in moulding risk perceptions. Motivation for the study: Literature suggests that one of the most significant challenges facing entrepreneurs is the development of a clear understanding of what it means to experience and conceptualise ‘risk’ within the context of business entrepreneurship. Research design, approach and method: Utilising data obtained from a random sample of 446 SME owner-managers in the south-east of England, this study employs a combination of tests, including a non-parametric test, Chi-square test and Cramer’s V statistics test, to derive a series of thematic propositions that contribute to our understanding of how these entrepreneurs perceive decision risk. Main findings: Findings highlight the situational decision factors that influence SME owner-managers to overemphasise possible negative outcomes, thus constraining the creative imagination upon which their entrepreneurship depends. Practical/managerial implications: It is generally accepted that decisions that may be highly innovative are not necessarily risky, unless the entity concerned is innovating in order to survive and its innovations have strategic significance. Based on this, we posit that there is an urgent need for entrepreneurs to focus less on risk associated with innovation and more on comprehensive analysis of all risk and uncertainty present around business-critical decisions. Contribution/value-add: This study contributes to growing research examining the relationship between SME risk and innovation, which is at present sparse.

    Full Text Available Objective: Burnout is conceptualized as a syndrome that consists of emotional exhaustion, depersonalization, and decreased personal accomplishment. Despite the increased frequency and severity of burnout in the Western world, there is limited published research regarding the experiences of clinical psychologists who have had burnout. The present study examines clinical psychologists’ different experiences of burnout in Australia.Design and Methods: In the year 2015, six privately practicing and solo-employed clinical psychologists provided rich qualitative data by participating in semi-structured interviews. Thematic analysis was the method used to analyze clinical psychologists’ natural accounts of their burnout experiences. Using NVivo, emerging themes were identified through coding ‘first order constructs’ and then axial code ‘second order constructs.’Findings: Clinical psychologists indicated that their roles are demanding and a diverse range of symptoms, including the enduring effects of burnout, mental stress, fatigue, decreased personal accomplishment, negative affect, depersonalization, reduced productivity and motivation, and insomnia. They identified precursors of burnout, including excessive workload and hours of work, life stresses, mismanaged workload, and transference. Clinical psychologists suggested that protective factors of burnout include knowledge and years worked in direct care, and trusting and long-term relationships. They indicated that the barriers to overcoming burnout include the fallacy that their clients’ expectations and needs are more important than their own, the financial cost of working in private practice, contemporary knowledge and inadequate education regarding self-care, and time constraints.Discussion and Conclusion: The findings presented in this study provide psychologists and other health professionals with an insight about the burnout experience and inform professionals of the mental

    Full Text Available The choice to bring this topic consists in choosing the creative vocation of the inventive painter Adem Kastrati, who articulates the artistic work with a unique technique, the usage of brown soil color, as a pictorial material and tool without artificial mixture, stressing also the application of the specific pictorial structure, which is considered unique up to now. Main objective of this paper is the analysis of the technical, thematic, symbolic and semiotic authenticity, in Adem Kastrati’s works, which is based on the Albanian traditional history. The artist’s tendency to create a form of art apprehensible to all, through the articulation of a clear figurative language which occupies a specific considered space in the paper, shows the artist’s message transmission to receptive level in reference to psychological-spiritual condition. This paper is based on primary and secondary sources, direct analysis of the artist’s activity, as well as different materials and publishing. As for the idea, technique, theme, variety of signs and symbols reflected, it is important to notice that the artist’ s skill is very original in the universe of inventive values of pictorial art that is why he occupies an important position in the Albanian culture. Consequently, this paper reflects a unique panorama of the authentic synthesis of specifications that characterize this artist’s activity. Therefore through this exposition, we are trying not only to highlight his creativity, but we are also trying to highlight his works to all the competent institutions nationwide, whose art was presented in 50 individual and collective exhibitions in different countries of the world.

    Background: The product of the educational nursing programs in Iran is training nurses who less have professional apprehension and commitment for participating in professional decisions. Whereas nurses especially those in high academic levels are expected to more involve in professional issues. Objective: The aim of this study was to explore Iranian nurse leaders’ experiences of making educational nursing policy with emphasizes on enhancement of nurses’ participation in professional decisions. Methods: We used a qualitative design with thematic analysis approach for data gathering and data analysis. Using purposive sampling we selected 17 experienced nurses in education and making educational nursing policies. Data gathered by open deep semi-structured face to face interviews. We followed six steps of Braun and Clarke for data analysis. Results: In order to enhance nurses’ participation in professional decisions they need to be well educated and trained to participate in community and meet community needs. The three main themes that evolved from analysis included opportunities available for training undergraduate students, challenges for PhD nurses and general deficiencies in nursing education. The second theme includes three sub-themes; namely, the PhD curriculum, PhD nurses’ attitudes and PhD nurses’ performance. Conclusions: We need for revising and directing nursing education toward service learning, community based need programs such as diabetes and driving accidents and also totally application of present educational opportunities. The specialization of nursing and the establishment of specialized nursing associations, the emphasis on teaching the science of care and reinforcing the sense of appreciation of pioneers of nursing in Iran are among the directions offered in the present study PMID:25946943

    Most patients with end-stage renal disease require dialysis to survive because they are unable to access kidney transplantation. Peritoneal dialysis (PD) is recommended by some clinical practice guidelines as the dialysis treatment of choice for adults without significant comorbid conditions or those with residual kidney function. This study aims to synthesize published qualitative studies of patients' experiences, beliefs, and attitudes about PD. We conducted a systematic review and thematic synthesis of qualitative studies of adult perspectives of living with PD. Databases (MEDLINE, Embase, PsycINFO, and CINAHL), theses, and reference lists were searched to November 2011. 39 studies involving 387 participants were included. We identified 7 themes: resilience and confidence (determination and overcoming vicissitudes), support structures (strong family relationship, peer support, professional dedication, social abandonment, and desire for holistic care), overwhelming responsibility (disruptive intrusion, family burden, and onerous treatment regimen), control (gaining bodily awareness, achieving independence and self-efficacy, and information seeking), freedom (flexibility and autonomy, retaining social functioning, and ability to travel), sick identity (damage to self-esteem and invisible suffering), and disablement (physical incapacitation and social loss and devaluation). PD can offer patients a sense of control, independence, self-efficacy, and freedom. However, holistic and multidisciplinary care is needed to mitigate the risks of impaired self-esteem, physical incapacitation, reduced social functioning, and poor sense of self-worth. Strategies that aim to strengthen social support and promote resilience and confidence in patients are integral to achieving positive adjustment, improved psychosocial outcomes, and treatment satisfaction.

    Childbirth is a leading reason for hospital admission in the USA, and most labour care is provided by registered nurses under physician or midwife supervision in a nurse-managed care model. Yet, there are no validated nurse-sensitive quality measures for maternity care. We aimed to engage primary stakeholders of maternity care in identifying the aspects of nursing care during labour and birth they believe influence birth outcomes, and how these aspects of care might be measured. This qualitative study used 15 focus groups to explore perceptions of 73 nurses, 23 new mothers and 9 physicians regarding important aspects of care. Transcripts were analysed thematically. Participants in the final six focus groups were also asked whether or not they thought each of five existing perinatal quality measures were nurse-sensitive. Nurses, new mothers and physicians identified nurses' support of and advocacy for women as important to birth outcomes. Support and advocacy actions included keeping women and their family members informed, being present with women, setting the emotional tone, knowing and advocating for women's wishes and avoiding caesarean birth. Mothers and nurses took technical aspects of care for granted, whereas physicians discussed this more explicitly, noting that nurses were their 'eyes and ears' during labour. Participants endorsed caesarean rates and breastfeeding rates as likely to be nurse-sensitive. Stakeholder values support inclusion of maternity nursing care quality measures related to emotional support and providing information in addition to physical support and clinical aspects of care. Care models that ensure labour nurses have sufficient time and resources to engage in the supportive relationships that women value might contribute to better health outcomes and improved patient experience.

    Full Text Available Introduction: In different German regions, seminar programs have been conducted for General practice residents. In each region, selection and teaching of learning content is conducted in a different manner. So far, no structured, standardized curriculum has been implemented nationwide. We have investigated, if the development of a common 5-year program of learning topics is conceivable between the different university departments of General practice in Germany.Method: The seminar program working group of the DEGAM (German College of General Practitioners and Family Physicians has conducted an online survey based on information gathered via preliminary telephone conference (n=7; physicians with postgraduate teaching experience among all German university departments of General Practice and two non-university teaching institutions, identified via the internet. 884 topics were extracted from 14 Seminar programs. The topics were entered in a database, discussed and categorized: Practice management/practice work flow/standardized documentation forms/quality management (n=33 topics, common acute and chronic diseases, including disease management programs (n=29 topics, communication, neurological, psychological and psychiatric consultations (n=24 topics, common medical problems, including eye, ear, nose, throat, skin and pediatric problems (n=99 Topics family physicians general approach, including epidemiology, shared decision making, test of time (n=42 Topics. These topics have been rated for priority and desirable number of teaching-units.Results: A catalogue of 111 topics was designed, encompassing 160 teaching units. There is a suggestion of wide topics collections plus an add-on catalogue.Conclusion: A proposal for a 5-year-thematic catalogue for postgraduate training of general practice residents in Germany has been developed. This newly developed curriculum has the potential to improve knowledge and skills that have not been covered during in

    Background: Decentralization of health systems has made sub-national/regional healthcare systems the backbone of healthcare delivery. These regions are tasked with the difficult responsibility of determining healthcare priorities and resource allocation amidst scarce resources. We aimed to review empirical literature that evaluated priority setting practice at the meso (sub-national) level of health systems. Methods: We systematically searched PubMed, ScienceDirect and Google scholar databases and supplemented these with manual searching for relevant studies, based on the reference list of selected papers. We only included empirical studies that described and evaluated, or those that only evaluated priority setting practice at the meso-level. A total of 16 papers were identified from LMICs and HICs. We analyzed data from the selected papers by thematic review. Results: Few studies used systematic priority setting processes, and all but one were from HICs. Both formal and informal criteria are used in priority-setting, however, informal criteria appear to be more perverse in LMICs compared to HICs. The priority setting process at the meso-level is a top-down approach with minimal involvement of the community. Accountability for reasonableness was the most common evaluative framework as it was used in 12 of the 16 studies. Efficiency, reallocation of resources and options for service delivery redesign were the most common outcome measures used to evaluate priority setting. Limitations: Our study was limited by the fact that there are very few empirical studies that have evaluated priority setting at the meso-level and there is likelihood that we did not capture all the studies. Conclusions: Improving priority setting practices at the meso level is crucial to strengthening health systems. This can be achieved through incorporating and adapting systematic priority setting processes and frameworks to the context where used, and making considerations of both process

    Radiation-induced damage in conifers adjacent to the damaged Chernobyl nuclear power plant has been evaluated using LANDSAT Thematic Mapper (TM) satellite images. Eight images acquired between 22 April 1986 and 15 May 1987 were used to assess the extent and magnitude of radiation effects on pine trees within 10 km of the reactor site. The timing and spatial extent of vegetation damaged was used to estimate the radiation doses in the near field around the Chernobyl nuclear power station and to indirectly derive the dose rates as a function of time during and after the accident. A normalized vegetation index was developed from the TM band data to visually demonstrate the damage and mortality to nearby conifer stands. The patterns of spectral change indicative of vegetation stress are consistent with changes expected for radiation injury and mortality. The extent and timing of these effects permitted the development of an integrated dose estimate, which was combined with the information regarding the characteristics of radionuclide mix, to provide an estimate of maximum dose rates during the early period of the accident. The derived peak dose rates during the 10-day release in the accident are high and are estimated at about 0.5 to 1 rad per hour. These are not considered life-threatening and would therefore require prompt but not immediate evacuation; that is, no off-site fatalities would be likely under such conditions. The methodology employed to combine remote-sensing analyses and the estimates of source term release with the known radiation effects on conifers represent a unique integration of these scientific and technical tools. The results of the study show that remote-sensing techniques can be used to develop a quantitative methodology for dosimetric applications and for future monitoring activities related to reactor safety

    Context-based chemistry education aims at making connections between real life and the scientific content of chemistry courses. The purpose of this study was to evaluate context-based chemistry studies. In looking for the context-based chemistry studies, the authors entered the keywords `context-based', `contextual learning' and `chemistry education' in well-known databases (i.e. Academic Search Complete, Education Research Complete, ERIC, Springer LINK Contemporary). Further, in case the computer search by key words may have missed a rather substantial part of the important literature in the area, the authors also conducted a hand search of the related journals. To present a detailed thematic review of context-based chemistry studies, a matrix was used to summarize the findings by focusing on insights derived from the related studies. The matrix incorporates the following themes: needs, aims, methodologies, general knowledge claims, and implications for teaching and learning, implications for curriculum development and suggestions for future research. The general knowledge claims investigated in this paper were: (a) positive effects of the context-based chemistry studies; (b) caveats, both are examined in terms of students' attitudes and students' understanding/cognition. Implications were investigated for practice in context- based chemistry studies, for future research in context- based chemistry studies, and for curriculum developers in context- based chemistry studies. Teachers of context-based courses claimed that the application of the context-based learning approach in chemistry education improved students' motivation and interest in the subject. This seems to have generated an increase in the number of the students who wish to continue chemistry education at higher levels. However, despite the fact that the majority of the studies have reported advantages of context-based chemistry studies, some of them have also referred to pitfalls, i.e. dominant

    Full Text Available Abstract Background Recruitment of eligible participants remains one of the biggest challenges to successful completion of randomised controlled trials (RCTs. Only one third of trials recruit on time, often requiring a lengthy extension to the recruitment period. We identified factors influencing recruitment success and potentially effective recruitment strategies. Methods We searched MEDLINE and EMBASE from 1966 to December Week 2, 2006, the Cochrane Library Methodology Register in December 2006, and hand searched reference lists for studies of any design which focused on recruitment to maternal/perinatal trials, or if no studies of maternal or perinatal research could be identified, other areas of healthcare. Studies of nurses' and midwives' attitudes to research were included as none specifically about trials were located. We synthesised the data narratively, using a basic thematic analysis, with themes derived from the literature and after discussion between the authors. Results Around half of the included papers (29/53 were specific to maternal and perinatal healthcare. Only one study was identified which focused on factors for maternal and perinatal clinicians and only seven studies considered recruitment strategies specific to perinatal research. Themes included: participant assessment of risk; recruitment process; participant understanding of research; patient characteristics; clinician attitudes to research and trials; protocol issues; and institutional or organisational issues. While no reliable evidence base for strategies to enhance recruitment was identified in any of the review studies, four maternal/perinatal primary studies suggest that specialised recruitment staff, mass mailings, physician referrals and strategies targeting minority women may increase recruitment. However these findings may only be applicable to the particular trials and settings studied. Conclusion Although factors reported by both participants and clinicians

    2005-01-01

    Full Text Available Background Corcoran (2000, 2001 has suggested that theory of mind judgements can be arrived at using analogical reasoning skills and she has proposed that this is the route that people with schizophrenia take when they make inferences about others' mental states. Recent work has demonstrated a robust relationship between mental state inference and autobiographical memory, providing initial support for the model. This study examines the model further by exploring the assertion that in schizophrenia the ability to infer the mental states of others also depends upon effective social reasoning in conditional contexts. Method 59 people with a DSM IV diagnosis of schizophrenia and 44 healthy subjects performed four versions of the thematic selection task. The versions varied according to the familiarity and social nature of the material they incorporated. The same subjects also completed the Hinting Task, a measure of theory of mind and tests of intellectual functioning and narrative recall. Results The schizophrenia and the normal control groups differed in their performance on all of the measures except that of intellectual functioning. Explorations within the schizophrenia group indicated that social reasoning was most markedly affected in the patients with negative signs and in those with paranoid delusions while for the hinting task, those with negative signs performed significantly worse than those in remission but this difference seemed to be due to these patients' poorer narrative memory. There was evidence in the schizophrenia data to support the hypothesis of a relationship between theory of mind and social conditional reasoning. Conclusion This work provided further support for the idea that in patients with schizophrenia at least, judgements about the mental states of others are achieved using analogical reasoning.

    Managing the complex fluid and diet requirements of chronic kidney disease (CKD) is challenging for patients. We aimed to summarize patients' perspectives of dietary and fluid management in CKD to inform clinical practice and research. Systematic review of qualitative studies. Adults with CKD who express opinions about dietary and fluid management. MEDLINE, EMBASE, PsycINFO, CINAHL, Google Scholar, reference lists, and PhD dissertations were searched to May 2013. Thematic synthesis. We included 46 studies involving 816 patients living in middle- to high-income countries. Studies involved patients treated with facility-based and home hemodialysis (33 studies; 462 patients), peritoneal dialysis (10 studies; 112 patients), either hemodialysis or peritoneal dialysis (3 studies; 73 patients), kidney transplant recipients (9 studies; 89 patients), and patients with non-dialysis-dependent CKD stages 1 to 5 (5 studies; 80 patients). Five major themes were identified: preserving relationships (interference with roles, social limitations, and being a burden), navigating change (feeling deprived, disrupting held truths, breaking habits and norms, being overwhelmed by information, questioning efficacy, and negotiating priorities), fighting temptation (resisting impositions, experiencing mental invasion, and withstanding physiologic needs), optimizing health (accepting responsibility, valuing self-management, preventing disease progression, and preparing for and protecting a transplant), and becoming empowered (comprehending paradoxes, finding solutions, and mastering change and demands). Limited data in non-English languages and low-income settings and for adults with CKD not treated with hemodialysis. Dietary and fluid restrictions are disorienting and an intense burden for patients with CKD. Patient-prioritized education strategies, harnessing patients' motivation to stay well for a transplant or to avoid dialysis, and viewing adaptation to restrictions as a collaborative

    Systemic lupus erythematosus (SLE) is a chronic inflammatory autoimmune disease that significantly impairs patients’ quality of life and can be life threatening. This study aimed to describe the experiences and perspectives of adults living with SLE. We conducted a systematic review and thematic synthesis of qualitative studies that explored the experiences of adults living with SLE. We searched MEDLINE, Embase, PsycINFO, CINAHL (to November week 1, 2012), Google Scholar, a thesis database, and reference lists of relevant articles. Forty-six studies involving 1,385 participants were included. Five themes were identified: restricted lifestyle(including subthemes of pervasive pain, debilitating fatigue, mental deterioration, disruptive episodic symptoms, and postponing parenthood), disrupted identity (gaining diagnostic closure, prognostic uncertainty, being a burden, hopelessness, heightened self-consciousness, fearing rejection, and guilt and punishment), societal stigma and indifference(illness trivialization, socially ostracized, and averse to differential treatment), gaining resilience (optimism, control and empowerment, being informed and involved, and valuing mutual understanding), and treatment adherence (preserving health, rapport with clinicians, negotiating medication regimens, and financial burden). SLE has a severe and pervasive impact on patients’ self-esteem and independence. Their physical and social functioning is limited and they feel anxious about their future. Patients perceive that SLE is trivialized, misunderstood,and stigmatized by their family, friends, and physicians, which intensifies their sense of isolation. Educational, psychosocial, and self-care interventions are needed to promote mental resilience, positive coping strategies, self-advocacy, and capacities for social participation, and thereby to achieve better treatment and health outcomes in patients with SLE.

We carried out a qualitative thematic analysis of the wall posts of a public Facebook group focused on dialysis to identify some of the major themes discussed. We searched Facebook using the word 'dialysis'. A Facebook group (Dialysis Discussion Uncensored) with the highest number of members was selected amongst publicly available forums related to dialysis and operated in English (http://www.facebook.com/groups/DialysisUncensored). Two researchers independently extracted information on features of the group including purpose, group members and the user-generated posts on the group wall. Posts were further analysed to develop major themes. Characteristics of a Facebook group based on its participants and activities are presented. Three themes are described with representative quotations. In a period of 2 weeks, we found 1257 wall posts with total of 31 636 likes and 15 972 comments. All messages were in English, and the majority of the participants were dialysis patients. However, we observed the participation of family members and care providers as well. Posts were categorized into three major themes: sharing information, seeking and providing emotional and social support and sharing experience. Findings of this study provide an example of how a social networking platform can enable patients and their families to share information and to encourage peer-based support for managing dialysis-related experiences. © 2016 Asian Pacific Society of Nephrology.

    Objective: Burnout is conceptualized as a syndrome that consists of emotional exhaustion, depersonalization, and decreased personal accomplishment. Despite the increased frequency and severity of burnout in the Western world, there is limited published research regarding the experiences of clinical psychologists who have had burnout. The present study examines clinical psychologists' different experiences of burnout in Australia. Design and Methods: In the year 2015, six privately practicing and solo-employed clinical psychologists provided rich qualitative data by participating in semi-structured interviews. Thematic analysis was the method used to analyze clinical psychologists' natural accounts of their burnout experiences. Using NVivo, emerging themes were identified through coding 'first order constructs' and then axial code 'second order constructs.' Findings: Clinical psychologists indicated that their roles are demanding and a diverse range of symptoms, including the enduring effects of burnout, mental stress, fatigue, decreased personal accomplishment, negative affect, depersonalization, reduced productivity and motivation, and insomnia. They identified precursors of burnout, including excessive workload and hours of work, life stresses, mismanaged workload, and transference. Clinical psychologists suggested that protective factors of burnout include knowledge and years worked in direct care, and trusting and long-term relationships. They indicated that the barriers to overcoming burnout include the fallacy that their clients' expectations and needs are more important than their own, the financial cost of working in private practice, contemporary knowledge and inadequate education regarding self-care, and time constraints. Discussion and Conclusion: The findings presented in this study provide psychologists and other health professionals with an insight about the burnout experience and inform professionals of the mental shortcomings of working as a solo

    Clinical practice guidelines (CPGs) aim to improve professionalism in health care. However, current CPG development manuals fail to address how to include ethical issues in a systematic and transparent manner. The objective of this study was to assess the representation of ethical issues in general CPGs on dementia care. To identify national CPGs on dementia care, five databases of guidelines were searched and national psychiatric associations were contacted in August 2011 and in June 2013. A framework for the assessment of the identified CPGs' ethical content was developed on the basis of a prior systematic review of ethical issues in dementia care. Thematic text analysis and a 4-point rating score were employed to assess how ethical issues were addressed in the identified CPGs. Twelve national CPGs were included. Thirty-one ethical issues in dementia care were identified by the prior systematic review. The proportion of these 31 ethical issues that were explicitly addressed by each CPG ranged from 22% to 77%, with a median of 49.5%. National guidelines differed substantially with respect to (a) which ethical issues were represented, (b) whether ethical recommendations were included, (c) whether justifications or citations were provided to support recommendations, and (d) to what extent the ethical issues were explained. Ethical issues were inconsistently addressed in national dementia guidelines, with some guidelines including most and some including few ethical issues. Guidelines should address ethical issues and how to deal with them to help the medical profession understand how to approach care of patients with dementia, and for patients, their relatives, and the general public, all of whom might seek information and advice in national guidelines. There is a need for further research to specify how detailed ethical issues and their respective recommendations can and should be addressed in dementia guidelines.

    Despite the relative abundance of frameworks and models to guide implementation science, the explicit use of theory is limited. Bringing together two seemingly disparate fields of research, this article asks, what can organisational theory offer implementation science? This is examined by applying a theoretical lens that incorporates agency, institutional, and situated change theories to understand the implementation of healthcare knowledge into practice. Interviews were conducted with 20 general practitioners (GPs) before and after using a resource to facilitate evidence-based sexual healthcare. Research material was analysed using two approaches - researcher-driven thematic coding and lexical analysis, which was relatively less researcher-driven. The theoretical lens elucidated the complex pathways of knowledge translation. More specifically, agency theory revealed tensions between the GP as agent and their organisations and patients as principals. Institutional theory highlighted the importance of GP-embeddedness within their chosen specialty of general practice; their medical profession; and the practice in which they worked. Situated change theory exposed the role of localised adaptations over time - a metamorphosis. This study has theoretical, methodological, and practical implications. Theoretically, it is the first to examine knowledge translation using a lens premised on agency, institutional, and situated change theories. Methodologically, the study highlights the complementary value of researcher-driven and researcher-guided analysis of qualitative research material. Practically, this study signposts opportunities to facilitate knowledge translation - more specifically, it suggests that efforts to shape clinician practices should accommodate the interrelated influence of the agent and the institution, and recognise that change can be ever so subtle.

    To explore the everyday experiences of children (aged ≤ 12 years) with Type 1 diabetes to identify factors that help or hinder diabetes self-management practices. Eight databases (Embase, Medline, CINAHL, Web of Science, PsychInfo, ASSIA, ERIC and ProQuest Dissertations) were searched in 2016 to identify qualitative studies exploring children's views about self-managing diabetes. Data were extracted, coded and analysed using thematic synthesis. Eighteen studies from five countries were included in the review. Synthesis of studies' findings resulted in the identification of three overarching analytical themes. The first theme, 'Understandings of diabetes and involvement in self-management', outlines ways in which children understand diabetes and develop self-management responsibilities. The second theme, 'Disruption to life and getting on with it', reports children's frustrations at disruptions to everyday life when managing diabetes, and how attempts to appear normal to family and friends affect self-management practices. The third theme, 'Friends' support', describes how friends' reactions and responses to diabetes affect children's ability to appear normal and willingness to disclose information about diabetes, and support provided by 'informed friends', or peers with diabetes. Although the synthesis has identified how children's everyday life experiences inform ways in which they undertake diabetes self-management, it was not possible to determine new ways to provide support. To help children optimise their glycaemic control, further work should be undertaken to identify their need for support and which takes into account the potential ways in which parents, friends and peers can offer assistance. © 2017 Diabetes UK.

    2001-12-01

    Universities across the nation are transforming their teaching and research efforts through increased use of a rapidly expanding menu of environmental data. With funding from the Division of Atmospheric Sciences (ATM ) of the National Science Foundation (NSF), the Unidata Program is playing a central role in this transformation by enabling universities to employ innovative computing and networking technologies to acquire such data sets in real-time and use them routinely in their classrooms and research labs. Working with the Unidata Program Center (UPC), the Unidata community, comprising over 140 departments, has built a national Internet Data Distribution (IDD ) system. The IDD allows users to "subscribe" to certain sets of data products; IDD servers then deliver the requested data to their local servers as soon as they are available from the source. With the initial national implementation in 1994, the IDD may have been the original example of Internet "push" technology. It now provides the reliability, flexibility, and efficiency required by participating institutions. As the underlying Internet technology evolves, we anticipate dramatic increases in the volume of data delivered. We plan to augment the system to better serve disciplines outside the atmospheric sciences and to incorporate anticipated new networking technologies to minimize the impact of the IDD on the underlying network. Unidata has recently undertaken a new initiative called THREDDS (THematic Real-time Environmental Distributed Data Services) under a grant from the NSF Division of Undergraduate Education NSDL (National Science, Math, Engineering, Technology Education Digital Library). The goal of THREDDs is to make it possible for students, educators and researchers to publish, contribute, find, and interact with data relating to the Earth system in a convenient, effective, and integrated fashion. Just as the World Wide Web and digital-library technologies have simplified the process of

    1977-01-01

    Methods for creating color thematic maps and land use tabulations, employing both Landsat imagery and computer image processing, are discussed. The system, the Multiple Input Land Use System (MILUS) has been tested in the metropolitan section of Dayton, Ohio. Training areas for land use were first digitized by coordinates and then transformed onto an image of white lines on a black background. This image was added to a Landsat image of the same area. Then multispectral classification was performed. A tape of digitized census tract boundaries was computer interfaced to yield an image of tract boundaries on a background registered to the thematic land-use map. Using a data management system, the data were then used to produce figures for the area and percent of land use in each tract. Future work is expected to convert most of the steps into interactive processing. This would greatly reduce the time needed to edit and register the data sets.

    2006-12-01

    Forest fires cause major losses to forest cover and disturb the ecological balance in our region. Rise in temperature during summer season causing increased dryness, increased activity of human beings in the forest areas, and the type of forest cover in the Garhwal Himalayas are some of the reasons that lead to forest fires. Therefore, generation of forest fire risk maps becomes necessary so that preventive measures can be taken at appropriate time. These risk maps shall indicate the zonation of the areas which are in very high, high, medium and low risk zones with regard to forest fire in the region. In this paper, an attempt has been made to generate the forest fire risk maps based on remote sensing data and other geographical variables responsible for the occurrence of fire. These include altitude, temperature and soil variations. Key thematic data layers pertaining to these variables have been generated using various techniques. A rule-based approach has been used and implemented in GIS environment to estimate fuel load and fuel index leading to the derivation of fire risk zonation index and subsequently to fire risk zonation maps. The fire risk maps thus generated have been validated on the ground for forest types as well as for forest fire risk areas. These maps would help the state forest departments in prioritizing their strategy for combating forest fires particularly during the fire seasons.

    Full Text Available Storytelling is recognized as a valid and important method of communicating information and knowledge gleaned from volumes of ever-accumulating data. Practices of data-driven storytelling in journalism and geovisual analytics have contributed to the development of geovisual stories; also called story maps. The benefits of student-focused multi-thematic atlases and digital storytelling methods in education can also be realized in story maps. An online, interactive version of the original paper version of the Wyoming Student Atlas was developed using story mapping technology. Studies on best practices for data-driven storytelling and web map interaction were used to inform the transition of the atlas from a traditional paper format to a collection of story maps. Evaluation of the atlas story maps for educational purposes was conducted by observing students from multiple classrooms as they used the story maps in a lesson. The students and educators responded to a survey after using the story maps. Results of the survey show positive responses to the atlas story maps, including ease of use and preference over a traditional paper atlas. However, certain types of interaction with the map resulted in increased negative or uncertain responses from students concerning their perception of the atlas story maps.

    Irrigation wells in a 41,000-square mile area located in Washington and northern Oregon were the subject of this study. Approximately 30,000 square miles of the area were mapped within the boundary of the Columbia Plateau, which covers some 48,200 square miles in the states of Washington, Oregon, and Idaho. Advanced state-of-the-art computer analysis techniques for processing Landsat digital multispectral data were used for mapping the area into ten land-use classes. Specially designed computer programs were used for mapping the locations of 1476 irrigation wells located in 13 counties. Six thematic color-encoded maps were prepared which show additional land-use types and relative areal distribution. Three maps depict the location of irrigation wells

    Full Text Available Remote sensing data analysis can provide thematic maps describing land-use and land-cover (LULC in a short period. Using proper image classification method in an area, is important to overcome the possible limitations of satellite imageries for producing land-use and land-cover maps. In the present study, a hierarchical hybrid image classification method was used to produce LULC maps using Landsat Thematic mapper TM for the year of 1998 and operational land imager OLI for the year of 2016. Images were classified using the proposed hybrid image classification method, vegetation cover crown percentage map from normalized difference vegetation index, Fisher supervised classification and object-based image classification methods. Accuracy assessment results showed that the hybrid classification method produced maps with total accuracy up to 84 percent with kappa statistic value 0.81. Results of this study showed that the proposed classification method worked better with OLI sensor than with TM. Although OLI has a higher radiometric resolution than TM, the produced LULC map using TM is almost accurate like OLI, which is because of LULC definitions and image classification methods used.

Application of time standpoint leads either to different kinds of the synoptic and prognostic maps production, which presents actual state of atmosphere in short time section in the past or in the near future or to the climatic maps production which presents longterm weather regime. Spatial standpoint then differs map works according to natural phenomenon proportions, whereas the scale of their graphic presentation can be different. It depends on production purpose of each work.In the paper there are analysed methods of mapping and climatic maps production, which display longterm regime of chosen atmospheric features. These athmosphere features are formed in interaction with land surface and also have direct influence on people and their activities throughout the country. At the same time they’re influenced by anthropogenic intervention to the landscape.

    Crowd sourcing geographic data is an opensource geographic data which is contributed by lots of non-professionals and provided to the public. The typical crowd sourcing geographic data contains GPS track data like OpenStreetMap, collaborative map data like Wikimapia, social websites like Twitter and Facebook, POI signed by Jiepang user and so on. These data will provide canonical geographic information for pubic after treatment. As compared with conventional geographic data collection and update method, the crowd sourcing geographic data from the non-professional has characteristics or advantages of large data volume, high currency, abundance information and low cost and becomes a research hotspot of international geographic information science in the recent years. Large volume crowd sourcing geographic data with high currency provides a new solution for geospatial database updating while it need to solve the quality problem of crowd sourcing geographic data obtained from the non-professionals. In this paper, a quality analysis model for OpenStreetMap crowd sourcing geographic data is proposed. Firstly, a quality analysis framework is designed based on data characteristic analysis of OSM data. Secondly, a quality assessment model for OSM data by three different quality elements: completeness, thematic accuracy and positional accuracy is presented. Finally, take the OSM data of Wuhan for instance, the paper analyses and assesses the quality of OSM data with 2011 version of navigation map for reference. The result shows that the high-level roads and urban traffic network of OSM data has a high positional accuracy and completeness so that these OSM data can be used for updating of urban road network database.

    2011-01-01

    Aerial photography interpretation is the most common mapping technique in the world. However, unlike an algorithm-based classification of satellite imagery, accuracy of aerial photography interpretation generated maps is rarely assessed. Vegetation communities covering an area of 530 km2 on Bullo River Station, Northern Territory, Australia, were mapped using an interpretation of 1:50,000 color aerial photography. Manual stereoscopic line-work was delineated at 1:10,000 and thematic maps generated at 1:25,000 and 1:100,000. Multivariate and intuitive analysis techniques were employed to identify 22 vegetation communities within the study area. The accuracy assessment was based on 50% of a field dataset collected over a 4 year period (2006 to 2009) and the remaining 50% of sites were used for map attribution. The overall accuracy and Kappa coefficient for both thematic maps was 66.67% and 0.63, respectively, calculated from standard error matrices. Our findings highlight the need for appropriate scales of mapping and accuracy assessment of aerial photography interpretation generated vegetation community maps.

    Despite the number of interprofessional team members caring for children at the end of life, little evidence exists on how institutions can support their staff in providing care in these situations. We sought to evaluate which aspects of the hospital work environment were most helpful for multidisciplinary team members who care for patients at the end of life and identify areas for improvement to better address staff needs. Qualitative thematic analysis was completed of free-text comments from a survey distributed to interprofessional staff members involved in the care of a recently deceased pediatric patient. A total of 2701 surveys were sent; 890 completed. Free-text responses were provided by 306 interprofessional team members. Interprofessional team members involved in the care of a child who died at a 348 bed academic children's hospital in the Midwestern United States. Realist thematic analysis of free-text responses was completed in Dedoose using a deductive and inductive approach with line-by-line coding. Descriptive statistics of demographic information was completed using Excel. Thematic analysis of the 306 free-text responses identified three main support-related themes. Interprofessional team members desire to have (1) support through educational efforts such as workshops, (2) support from colleagues, and (3) support through institutional practices. Providers who participate in end-of-life work benefit from ongoing support through education, interpersonal relationships, and institutional practices. Addressing these areas from an interprofessional perspective enables staff to provide the optimal care for patients, patients' families, and themselves.

    NIH Mentored Career Development (K) Awards bridge investigators from mentored to independent research. A smaller proportion of women than men succeed in this transition. The aim of this qualitative study was to analyze reviewers' narrative critiques of K award applications and explore thematic content of feedback provided to male and female applicants. We collected 88 critiques, 34 from 9 unfunded and 54 from 18 funded applications, from 70% (n = 26) of investigators at the University of Wisconsin-Madison with K awards funded between 2005 and 2009 on the first submission or after revision. We qualitatively analyzed text in the 5 critique sections: candidate, career development plan, research plan, mentors, and environment and institutional commitment. We explored thematic content within these sections for male and female applicants and for applicants who had received a subsequent independent research award by 2014. Themes revealed consistent areas of criticism for unfunded applications and praise for funded applications. Subtle variations in thematic content appeared for male and female applicants: For male applicants criticism was often followed by advice but for female applicants it was followed by questions about ability; praise recurrently characterized male but not female applicants' research as highly significant with optimism for future independence. Female K awardees that obtained subsequent independent awards stood out as having track records described as "outstanding." This exploratory study suggests that K award reviewer feedback, particularly for female applicants, should be investigated as a potential contributor to research persistence and success in crossing the bridge to independence.

    EPOS Thematic Core Service ANTHROPOGENIC HAZARDS (TCS AH) aims to create new research opportunities in the field of anthropogenic hazards evoked by exploitation of georesources. TCS AH, based on the prototype built in the framework of the IS-EPOS project (https://tcs.ah-epos.eu/), financed from Polish structural funds (POIG.02.03.00-14-090/13-00), is being further developed within EPOS IP project (H2020-INFRADEV-1-2015-1, INFRADEV-3-2015). TCS AH is designed as a functional e-research environment to ensure a researcher the maximum possible freedom for in silico experimentation by providing a virtual laboratory in which researcher will be able to create own workspace with own processing streams. The unique integrated RI is: (i) data gathered in the so- called "episodes", comprehensively describing a geophysical process, induced or triggered by human technological activity, which under certain circumstances can become hazardous for people, infrastructure and the environment and (ii) problem-oriented, specific high-level services, with the particular attention devoted to methods analyzing correlations between technology, geophysical response and resulting hazard. Services to be implemented are grouped within six blocks: (1) Basic services for data integration and handling; (2) Services for physical models of stress/strain changes over time and space as driven by geo-resource production; (3) Services for analysing geophysical signals; (4) Services to extract the relation between technological operations and observed induced seismic/deformation; (5) Services to quantitative probabilistic assessments of anthropogenic seismic hazard - statistical properties of anthropogenic seismic series and their dependence on time-varying anthropogenesis; ground motion prediction equations; stationary and time-dependent probabilistic seismic hazard estimates, related to time-changeable technological factors inducing the seismic process; (6) Simulator for Multi

    Barefoot running describes when individuals run without footwear. Minimalist running utilizes shoes aimed to mimic being barefoot. Although these forms of running have become increasingly popular, we still know little about how recreational runners perceive them. In-depth interviews with eight recreational runners were used to gather information about their running experiences with a focus on barefoot and minimalist running. Interviews were analysed using a latent level thematic analysis to identify and interpret themes within the data. Although participants considered barefoot running to be 'natural', they also considered it to be extreme. Minimalist running did not produce such aversive reactions. 'Support' reassured against concerns and was seen as central in protecting vulnerable body parts and reducing impact forces, but lacked a common or clear definition. A preference for practical over academic knowledge was found. Anecdotal information was generally trusted, as were running stores with gait assessment, but not health professionals. People often have inconsistent ideas about barefoot and minimalist running, which are often formed by potentially biased sources, which may lead people to make poor decisions about barefoot and minimalist running. It is important to provide high-quality information to enable better decisions to be made about barefoot and minimalist running. What is already known on this subject? There is no known work on the psychology behind barefoot and minimalist running. We believe our study is the first qualitative study to have investigated views of this increasingly popular form of running. What does this study add? The results suggest that although barefoot running is considered 'natural', it is also considered 'extreme'. Minimalist running, however, did not receive such aversive reactions. 'Support' was a common concern among runners. Although 'support' reassured against concerns and was seen as central in protecting vulnerable body

    Glacierized regions are one of the most dynamic land surface environments on the planet (Evans and Delaney, In Press). They are susceptible to various types of natural hazards such as landslides, glacier avalanches, and glacial lake outburst floods (GLOF). GLOF events are increasingly common and present catastrophic flood hazards, the causes of which are sensitive to climate change in complex high mountain topography (IPCC, 2013). Inundation and debris flows from GLOF events have repeatedly caused significant infrastructure damages and loss of human lives in the high mountain regions of the world (Huggel et al, 2002). The research is designed to develop methods for the consistent detection of glacier lakes formation during the Landsat Thematic Mapper (TM) era (1982 - present), to quantify the frequency of glacier lake development and estimate lake volume using Landsat imagery and digital elevation model (DEM) data. Landsat TM scenes are used to identify glacier lakes in the Shimshal and Shaksgam valley, particularly the development of Lake Virjeab in year 2000 and Kyagar Lake in 1998. A simple thresholding technique using Landsat TM infrared bands, along with object-based segmentation approaches are used to isolate lake extent. Lake volume is extracted by intersecting the lake extent with the DEM surface. Based on previous studies and DEM characterization in the region, Shuttle Radar Topography Mission (SRTM) DEM is preferred over Advanced Spaceborne Thermal Emission and Reflection (ASTER) GDEM due to higher accuracy. Calculated errors in SRTM height estimates are 5.81 m compared with 8.34 m for ASTER. SRTM data are preferred because the DEM measurements were made over short duration making the DEM internally consistent. Lake volume derived from the Landsat TM imagery and DEM are incorporated into a simple GLOF model identified by Clague and Matthews (1973) to estimate the potential peak discharge (Qmax) of a GLOF event. We compare the simple Qmax estimates with

    Community acupuncture is a recent innovation in acupuncture service delivery in the U.S. that aims to improve access to care through low-cost treatments in group-based settings. Patients at community acupuncture clinics represent a broader socioeconomic spectrum and receive more frequent treatments compared to acupuncture users nationwide. As a relatively new model of acupuncture in the U.S., little is known about the experiences of patients at community acupuncture clinics and whether quality of care is compromised through this high-volume model. The aim of this study was to assess patients' perspectives on the care received through community acupuncture clinics. The investigators conducted qualitative, thematic analysis of written comments from an observational, cross-sectional survey of clients of the Working Class Acupuncture clinics in Portland, Oregon. The survey included an open-ended question for respondents to share comments about their experiences with community acupuncture. Comments were received from 265 community acupuncture patients. Qualitative analysis of written comments identified two primary themes that elucidate patients' perspectives on quality of care: 1) aspects of health care delivery unique to community acupuncture, and 2) patient engagement in health care. Patients identified unique aspects of community acupuncture, including structures that facilitate access, processes that make treatments more comfortable and effective and holistic outcomes including physical improvements, enhanced quality of life, and empowerment. The group setting, community-based locations, and low cost were highlighted as aspects of this model that allow patients to access acupuncture. Patients' perspectives on the values and experiences unique to community acupuncture offer insights on the quality of care received in these settings. The group setting, community-based locations, and low cost of this model potentially reduce access barriers for those who might not

    People affected by neuromuscular disorders can experience adverse psychosocial consequences and difficulties accessing information and support. Online support groups provide new opportunities for peer support. The aim of this study was to understand how contributors used the message board function of a newly available neuromuscular disorders online support group. Message postings (n = 1951) from the first five months of the message board of a newly formed online support group for neuromuscular disorders hosted by a charitable organization were analyzed using inductive thematic analysis. Members created a sense of community through disclosing personal information, connecting with people with similar illness experiences or interests, welcoming others and sharing aspirations for the development of a resourceful community. Experiences, emotional reactions and support were shared in relation to: delayed diagnosis; symptom interpretation; illness management and progression; the isolating impact of rare disorders; and the influence of social and political factors on illness experiences. This study provided a novel insight into individuals' experiences of accessing a newly available online support group for rare conditions hosted by a charitable organization. The findings highlight how the online support group provided an important peer support environment for members to connect with others, exchange information and support and engender discussion on political and social issues unique to living with often-rare neuromuscular disorders. Online support groups may therefore provide an important and easily accessible support outlet for people with neuromuscular disorders as well as a platform for empowering members to raise awareness about the impact of living with these conditions. Further research is needed to examine member motivations for using such groups and any effects of participation in greater detail. Implications for rehabilitation Online support groups may

    The Southern African Regional Science Initiative (SAFARI 2000) was a major surface, airborne, and spaceborne field campaign carried out in southern Africa in 2000 and 2001 that addressed a broad range of phenomena related to land-atmosphere interactions and the biogeochemical functioning of the southern African system. This paper presents a thematic analysis and integration of the Journal of Geophysical Research SAFARI 2000 Special Issue, presenting key findings of an intensive field campaign over southern Africa in August and September of 2000. The integrating themes deal with surface emissions characterization; airborne characterizations of aerosols and trace gases; regional haze and trace gas characterization; and radiant measurements by surface, aircraft, and remote sensing platforms. Enhanced regional fuel loads associated with the moist La Niña phase of the El Niño-Southern Oscillation (ENSO) cycle produced above average biomass burning emissions, which consequently dominated all other aerosol and trace gas emissions during the dry season. Southward transport of a broad plume of smoke originating in equatorial Africa and exiting off the east coast toward the Indian Ocean (the river of smoke) is attributed to unusual synoptic airflows associated the ENSO phase. New and revised biogenic and pyrogenic emission factors are reported, including a number of previously unreported oxygenated organic compounds and inorganic compounds from biomass combustion. Emission factors are scaled up to regional emission surfaces for biogenic species utilizing species specific and light-dependent emission factors. Fire scar estimates reveal contradictory information on the timing of the peak and extent of the biomass-burning season. Integrated tall stack coordinated measurements (between ground, airborne and remotely sensing platforms) of upwelling and downwelling radiation in massive thick aerosol layers covering much of southern Africa yield consistent estimates of large

    Full Text Available Abstract This thematic collection contains eight papers mostly presented at the 2016 AOGS meeting in Beijing. Four papers describe historical earthquake studies in Europe, Japan, and China; one paper uses modern instrumental data to examine the effect of giant earthquakes on the seismicity rate; and three papers describe paleoseismological studies using tsunami deposit in Japan, marine terraces in Philippines, and active faults in Himalayas. Hammerl (Geosci Lett 4:7, 2017 introduced historical seismological studies in Austria, starting from methodology which is state of the art in most European countries, followed by a case study for an earthquake of July 17, 1670 in Tyrol. Albini and Rovida (Geosci Lett 3:30, 2016 examined 114 historical records for the earthquake on April 6, 1667 on the east coast of the Adriatic Sea, compiled 37 Macroseismic Data Points, and estimated the epicenter and the size of the earthquake. Matsu’ura (Geosci Lett 4:3, 2017 summarized historical earthquake studies in Japan which resulted in about 8700 Intensity Data Points, assigned epicenters for 214 earthquakes between AD 599 and 1872, and estimated focal depth and magnitudes for 134 events. Wang et al. (Geosci Lett 4:4, 2017 introduced historical seismology in China, where historical earthquake archives include about 15,000 sources, and parametric catalogs include about 1000 historical earthquakes between 2300 BC and AD 1911. Ishibe et al. (Geosci Lett 4:5, 2017 tested the Coulomb stress triggering hypothesis for three giant (M~9 earthquakes that occurred in recent years, and found that at least the 2004 Sumatra–Andaman and 2011 Tohoku earthquakes caused the seismicity rate change. Ishimura (2017 re-estimated the ages of 11 tsunami deposits in the last 4000 years along the Sanriku coast of northern Japan and found that the average recurrence interval of those tsunamis as 350–390 years.

    The THENPHEBISP 2-year thematic network started in December 2001, and was concerned with OECD/CSNI International Standard Problem 46, itself based on the Phebus FPT1 core degradation/source term experiment. The aim was to assess the capability of computer codes to model in an integrated way the physical processes taking place during a severe accident in a pressurised water reactor, from the initial stages of core degradation, the fission product transport through the primary circuit and the behaviour of the released fission products in the containment. ISP-46, coordinated by IRSN/DRS Cadarache, attracted 33 participating organisations, from 23 countries and international bodies, who submitted 47 base case calculations and 21 best-estimate calculations, using 15 different codes. The thermal behaviour of the fuel bundle and the hydrogen production were generally well captured, and good agreement for the core final state could be obtained with a suitable choice of bulk fuel relocation temperature, however this is unlikely to be representative of all plant studies so sensitivity calculations are needed with the modelling in its current state. Total volatile fission product release was simulated, but its kinetics, and the overall modelling of semi-volatile, low-volatile and structural material release (Ag/In/Cd, Sn) needs improvement. Overall retention in the circuit is well predicted, but calculations underestimate deposits in the upper plenum and overestimate those in the steam generator, also the volatility of some elements could be better predicted. Containment thermal hydraulics and depletion rate of aerosols are well calculated, but with difficulties related to partition amongst the deposition mechanisms. Calculation of iodine chemistry in the containment turned out to be more difficult. Its quality strongly depends of the calculation of release and transport in the integral codes. The major difficulties are related to the existence of gaseous iodine in the

  18. Comparing the performance of various digital soil mapping approaches to map physical soil properties

    2015-04-01

    Spatial information on physical soil properties is intensely expected, in order to support environmental related and land use management decisions. One of the most widely used properties to characterize soils physically is particle size distribution (PSD), which determines soil water management and cultivability. According to their size, different particles can be categorized as clay, silt, or sand. The size intervals are defined by national or international textural classification systems. The relative percentage of sand, silt, and clay in the soil constitutes textural classes, which are also specified miscellaneously in various national and/or specialty systems. The most commonly used is the classification system of the United States Department of Agriculture (USDA). Soil texture information is essential input data in meteorological, hydrological and agricultural prediction modelling. Although Hungary has a great deal of legacy soil maps and other relevant soil information, it often occurs, that maps do not exist on a certain characteristic with the required thematic and/or spatial representation. The recent developments in digital soil mapping (DSM), however, provide wide opportunities for the elaboration of object specific soil maps (OSSM) with predefined parameters (resolution, accuracy, reliability etc.). Due to the simultaneous richness of available Hungarian legacy soil data, spatial inference methods and auxiliary environmental information, there is a high versatility of possible approaches for the compilation of a given soil map. This suggests the opportunity of optimization. For the creation of an OSSM one might intend to identify the optimum set of soil data, method and auxiliary co-variables optimized for the resources (data costs, computation requirements etc.). We started comprehensive analysis of the effects of the various DSM components on the accuracy of the output maps on pilot areas. The aim of this study is to compare and evaluate different

    2016-09-01

    Full Text Available In the article, the concept of landscape maps by Franciszek Uhorczak (1902–1981, Professor of the Maria Curie-Skłodowska University in Lublin, was discussed. The maps constitute a cartographic illustration of volume III, IV and V of “Universal Geography” edited by Państwowe Wydawnictwo Naukowe (the National Scientific Publishing House (Warsaw 1965–1967 – the first Polish small-scale landscape maps of the world. From the perspective of the 50s, an attempt was undertaken to assess the editorial assumptions, landscape typology and selection of cartographic means used by the author, paying special attention to the selection of colours representing landscapes. Also, issues raising controversies related to the degree of generalization of particular elements of the content, typology of landscapes as well as map details were indicated. The performed analysis leads to the conclusion that landscape maps by Professor F. Uhorczak constituted one of the most significant achievements of Polish thematic cartography of the 20th century, and they are an unequaled model also for the contemporary cartographers.

  4. Evaluating the Use of an Object-Based Approach to Lithological Mapping in Vegetated Terrain

    2016-10-01

    Full Text Available Remote sensing-based approaches to lithological mapping are traditionally pixel-oriented, with classification performed on either a per-pixel or sub-pixel basis with complete disregard for contextual information about neighbouring pixels. However, intra-class variability due to heterogeneous surface cover (i.e., vegetation and soil or regional variations in mineralogy and chemical composition can result in the generation of unrealistic, generalised lithological maps that exhibit the “salt-and-pepper” artefact of spurious pixel classifications, as well as poorly defined contacts. In this study, an object-based image analysis (OBIA approach to lithological mapping is evaluated with respect to its ability to overcome these issues by instead classifying groups of contiguous pixels (i.e., objects. Due to significant vegetation cover in the study area, the OBIA approach incorporates airborne multispectral and LiDAR data to indirectly map lithologies by exploiting associations with both topography and vegetation type. The resulting lithological maps were assessed both in terms of their thematic accuracy and ability to accurately delineate lithological contacts. The OBIA approach is found to be capable of generating maps with an overall accuracy of 73.5% through integrating spectral and topographic input variables. When compared to equivalent per-pixel classifications, the OBIA approach achieved thematic accuracy increases of up to 13.1%, whilst also reducing the “salt-and-pepper” artefact to produce more realistic maps. Furthermore, the OBIA approach was also generally capable of mapping lithological contacts more accurately. The importance of optimising the segmentation stage of the OBIA approach is also highlighted. Overall, this study clearly demonstrates the potential of OBIA for lithological mapping applications, particularly in significantly vegetated and heterogeneous terrain.

    2017-12-01

    Caves are the result of solution processes. Because they are happened from geochemical and tectonic activity, they can be considered as geosphere phenomena. As one of the geosphere phenomena, especially at karst landform, caves have spatial dimensions and aspects. Cave’s utilizations and developments are increasing in many sectors such as hydrology, earth science, and tourism industry. However, spatial aspects of caves are poorly concerned dues to the lack of recognition toward cave maps. Many stakeholders have not known significances and importance of cave maps in determining development of a cave. Less information can be considered as the cause. Therefore, it is strongly necessary to put cave maps into the right context in order to make stakeholders realize the significance of it. Also, cave maps will be officially regarded as tools related to policy, development, and conservation act of caves hence they will have regulation in the usages and applications. This paper aims to make the contextualization of cave maps toward legal act. The act which is used is Act Number 4 Year 2011 About Geospatial Information. The contextualization is done by scrutinizing every articles and clauses related to cave maps and seek the contextual elements from both of them. The results are that cave maps can be regarded as geospatial information and classified as thematic geospatial information. The usages of them can be regulated through the Act Number 4 Year 2011. The regulations comprised by data acquisition, database, authorities, surveyor, and the obligation of providing cave maps in planning cave’s development and the environment surrounding.

    Research, monitoring and management of large marine protected areas require detailed and up-to-date habitat maps. Ningaloo Marine Park (including the Muiron Islands) in north-western Australia (stretching across three degrees of latitude) was mapped to 20 m depth using HyMap airborne hyperspectral imagery (125 bands) at 3.5 m resolution across the 762 km2 of reef environment between the shoreline and reef slope. The imagery was corrected for atmospheric, air-water interface and water column influences to retrieve bottom reflectance and bathymetry using the physics-based Modular Inversion and Processing System. Using field-validated, image-derived spectra from a representative range of cover types, the classification combined a semi-automated, pixel-based approach with fuzzy logic and derivative techniques. Five thematic classification levels for benthic cover (with probability maps) were generated with varying degrees of detail, ranging from a basic one with three classes (biotic, abiotic and mixed) to the most detailed with 46 classes. The latter consisted of all abiotic and biotic seabed components and hard coral growth forms in dominant or mixed states. The overall accuracy of mapping for the most detailed maps was 70% for the highest classification level. Macro-algal communities formed most of the benthic cover, while hard and soft corals represented only about 7% of the mapped area (58.6 km2). Dense tabulate coral was the largest coral mosaic type (37% of all corals) and the rest of the corals were a mix of tabulate, digitate, massive and soft corals. Our results show that for this shallow, fringing reef environment situated in the arid tropics, hyperspectral remote sensing techniques can offer an efficient and cost-effective approach to mapping and monitoring reef habitats over large, remote and inaccessible areas.

    Full Text Available Abstract Background Communication is of paramount importance in responding to health crises. We studied the media messages put forth by different stakeholders in two Ebola vaccine trials that became controversial in Ghana. These interactions between health authorities, political actors, and public citizens can offer key lessons for future research. Through an analysis of online media, we analyse stakeholder concerns and incentives, and the phases of the dispute, to understand how the dispute evolved to the point of the trials being suspended, and analyse what steps might have been taken to avert this outcome. Methods A web-based system was developed to download and analyse news reports relevant to Ebola vaccine trials. This included monitoring major online newspapers in each country with planned clinical trials, including Ghana. All news articles were downloaded, selecting out those containing variants of the words “Ebola,” and “vaccine,” which were analysed thematically by a team of three coders. Two types of themes were defined: critiques of the trials and rebuttals in favour of the trials. After reconciling differences between coders’ results, the data were visualised and reviewed to describe and interpret the debate. Results A total of 27,460 articles, published between 1 May and 30 July 2015, were collected from nine different newspapers in Ghana, of which 139 articles contained the keywords and met the inclusion criteria. The final codebook included 27 themes, comprising 16 critiques and 11 rebuttals. After coding and reconciliation, the main critiques (and their associated rebuttals were selected for in-depth analysis, including statements about the trials being secret (mentioned in 21% of articles, claims that the vaccine trials would cause an Ebola outbreak in Ghana (33%, and the alleged impropriety of the incentives offered to participants (35%.

A total of 27,460 articles, published between 1 May and 30 July 2015, were collected from nine different newspapers in Ghana, of which 139 articles contained the keywords and met the inclusion criteria. The final codebook included 27 themes, comprising 16 critiques and 11 rebuttals. After coding and reconciliation, the main critiques (and their associated rebuttals) were selected for in-depth analysis, including statements about the trials being secret (mentioned in 21% of articles), claims that the vaccine trials would cause an Ebola outbreak in Ghana (33%), and the alleged impropriety of the incentives offered to participants (35%). Perceptions that the trials were "secret" arose from a combination of premature news reporting and the fact that the trials were prohibited

    thematically analysed. Participants reported unreasonable demands during clinical blocks, and described how control/support is lowest on placements with staff shortages. Negative attitudes towards students from staff and related issues were also discussed. Younger participants described struggling with mental health work during the early stages of training. Training providers should strive to provide adequate support to students to help them manage stress during training. Implications for practice Academic demands should be reasonable during clinical blocks and support services outside normal working hours should be available for students, even if these are limited in scope. Greater consideration to the allocation of placements for younger students in the mental health branch could be helpful. Furthermore, staff on placements should be aware of the tasks students can and cannot perform, to help improve staff/student relations. Educating students on the issues of raising concerns can help the government's drive for a more open and transparent National Health Service (NHS). © 2015 The Authors.

    After the successful completion of the EPOS Preparatory Phase, the community of European Research Infrastructures in Seismology is now moving ahead with the build-up of the Thematic Core Service (TCS) for Seismology in EPOS, EPOS-Seismology. Seismology is a domain where European-level infrastructures have been developed since decades, often supported by large-scale EU projects. Today these infrastructures provide services to access earthquake waveforms (ORFEUS), parameters (EMSC) and hazard data and products (EFEHR). The existing organizations constitute the backbone of infrastructures that also in future will continue to manage and host the services of the TCS EPOS-Seismology. While the governance and internal structure of these organizations will remain active, and continue to provide direct interaction with the community, EPOS-Seismology will provide the integration of these within EPOS. The main challenge in the build-up of the TCS EPOS-Seismology is to improve and extend these existing services, producing a single framework which is technically, organizationally and financially integrated with the EPOS architecture, and to further engage various kinds of end users (e.g. scientists, engineers, public managers, citizen scientists). On the technical side the focus lies on four major tasks: - the construction of the next generation software architecture for the European Integrated (waveform) Data Archive EIDA, developing advanced metadata and station information services, fully integrate strong motion waveforms and derived parametric engineering-domain data, and advancing the integration of mobile (temporary) networks and OBS deployments in EIDA; - the further development and expansion of services to access seismological products of scientific interest as provided by the community by implementing a common collection and development (IT) platform, improvements in the earthquake information services e.g. by introducing more robust quality indicators and diversifying

    Science.gov (United States)

    Eugenia, Marcu

    2015-04-01

    The name Roşia Montană, situated in Transylvania, became well known after a Romanian-Canadian company, Roşia Montană Gold Company (RMGC), obtained the concession license on exploitation for gold and silver minerals in the Roşia Montană area. The project consists of opening the largest surface gold mines in Europe using cyanide, which will include four open pits and a processing plant for gold and silver in The Roşia Valley and a tailings facility with an area of 367 hectares in the Corna Valley. One of the main fears is related to a possible ecological accident like the one in Baia Mare in 2000, when a tailing facility dam break led to cyanide pollution of Tisa and Danube rivers that resulted in the death of 1,200 tons of fish and contamination of water resources for 2 million people. This thematic trip is important for the scientific preparation of students and an opportunity to educate them in the spirit of environmental protection. The training and education of students will require assimilation and understanding, actively and consciously, using the knowledge acquired during the compulsory curriculum and training skills. REASON: The continuous degradation of the environment is a major crisis due to human intervention in nature, and the proposed Roşia Montană mining project will continue this trend. The company proposes to extract gold from mines by using the gold separation technique using cyanide, a process that involves destroying a total area of 16 km² which includes 5 mountains, 7 churches, 11 cemeteries and the ruins of Alburnus Maior Citadel, as well as creating pollution that would last for hundreds of years. The extraction of gold from low-grade ores using cyanide processes was estimated to result in a worldwide emission of 45,300 tons of hydrogen cyanide. Environmental education for a healthy life has children as target group, because they are the trustees and beneficiaries of tomorrow's natural resources and can influence the attitudes of

    2016-04-01

    EPOS has been designed with the vision of creating a pan-European infrastructure for solid Earth science to support a safe and sustainable society. In accordance with this scientific vision, the EPOS mission is to integrate the diverse and advanced European Research Infrastructures for solid Earth science relying on new e-science opportunities to monitor and unravel the dynamic and complex Earth System. EPOS will enable innovative multidisciplinary research for a better understanding of the Earth's physical and chemical processes that control earthquakes, volcanic eruptions, ground instability and tsunami as well as the processes driving tectonics and Earth's surface dynamics. To accomplish its mission, EPOS is engaging different stakeholders, not limited to scientists, to allow the Earth sciences to open new horizons in our understanding of the planet. EPOS also aims at contributing to prepare society for geo-hazards and to responsibly manage the exploitation of geo-resources. Through integration of data, models and facilities, EPOS will allow the Earth science community to make a step change in developing new concepts and tools for key answers to scientific and socio-economic questions concerning geo-hazards and geo-resources as well as Earth sciences applications to the environment and human welfare. A long-term integration plan is necessary to accomplish the EPOS mission. EPOS is presently in its implementation phase further extending its pan-European dimension. The EPOS Implementation Phase builds on the achievements of the successful EPOS Preparatory Phase project and consists of two key activities: the legal establishment of the EPOS-ERIC and the EPOS IP project. The EPOS implementation phase will last from 2015 to 2019. Key objectives of the project are: implementing Thematic Core Services (TCS), the domain-specific service hubs for coordinating and harmonizing national resources/plans with the European dimension of EPOS; building the Integrated Core

  13. ICAP: An Interactive Cluster Analysis Procedure for analyzing remotely sensed data. [to classify the radiance data to produce a thematic map

    Wharton, S. W.

    1980-01-01

    An Interactive Cluster Analysis Procedure (ICAP) was developed to derive classifier training statistics from remotely sensed data. The algorithm interfaces the rapid numerical processing capacity of a computer with the human ability to integrate qualitative information. Control of the clustering process alternates between the algorithm, which creates new centroids and forms clusters and the analyst, who evaluate and elect to modify the cluster structure. Clusters can be deleted or lumped pairwise, or new centroids can be added. A summary of the cluster statistics can be requested to facilitate cluster manipulation. The ICAP was implemented in APL (A Programming Language), an interactive computer language. The flexibility of the algorithm was evaluated using data from different LANDSAT scenes to simulate two situations: one in which the analyst is assumed to have no prior knowledge about the data and wishes to have the clusters formed more or less automatically; and the other in which the analyst is assumed to have some knowledge about the data structure and wishes to use that information to closely supervise the clustering process. For comparison, an existing clustering method was also applied to the two data sets.

    2007-01-01

    NASA and the US Geological Survey (USGS) are seeking to generate a map of the entire globe using Landsat 5 Thematic Mapper (TM) and Landsat 7 Enhanced Thematic Mapper Plus (ETM+) sensor data from the "mid-decadal" period of 2004 through 2006. The global map is comprised of thousands of scene locations and, for each location, tens of different images of varying quality to chose from. Furthermore, it is desirable for images of adjacent scenes be close together in time of acquisition, to avoid obvious discontinuities due to seasonal changes. These characteristics make it desirable to formulate an automated solution to the problem of generating the complete map. This paper formulates a Global Map Generator problem as a Constraint Optimization Problem (GMG-COP) and describes an approach to solving it using local search. Preliminary results of running the algorithm on image data sets are summarized. The results suggest a significant improvement in map quality using constraint-based solutions.

    Full Text Available The article deals with the features of the spatial representation of the location of objects and phenomena on the Earth. One of the types of “cartographic representation” is modeling on the contour map. The advantages of the method are revealed. The application of modeling techniques that allows one to include ethnogeographic data in the content of the characteristics of the territory and reflect them on the contour map. The basis of ethnogeographic modeling is the identification and creation of elements of the material and spiritual culture of peoples by means of conventional signs. Comparison of these elements, their superimposition with respect to each other, as well as their comparison with geographic maps allow us to determine the interrelations and the dependence of the phenomenon. Modeling on contour maps is the basic method of learning in geography. On the one hand, it creates a cartographic image of the studied territory, and on the other hand it facilitates the creation of “visual supports” on the map.Modeling on contour maps, at the beginning students put the basic geographical names, which will serve as the basic knowledge. Then, by purposefully analyzing and comparing the thematic maps of the atlas or textbook, the students reflect specific ethno-geographical knowledge on contour maps. As a result, contour maps acquire “their own face”, and do not become a simple copy of maps of an atlas or textbook.Also, the features of the effect of this technique on the formation of spatial representations about the studied object have been analyzed. Thanks to the cartographic model, one can maintain a constant cognitive interest in the material studied. Modeling on the contour map will allow one to present the structure of the links between the elements of the ethnogeographical material. The basis of ethnogeographic modeling on the contour map is the identification and mapping of elements of the material and spiritual culture of

    2013-12-01

    Full Text Available This work proposes a trophic state index based on the remote sensing retrieval of chlorophyll-α concentration. For that, in situ Bidirectional Reflectance Factor (BRF data acquired in the Ibitinga reservoir were resampled to match Landsat/TM spectral simulated bands (TM_sim bands and used to run linear correlation with concurrent measurements of chlorophyll-α concentration. Monte Carlo simulation was then applied to select the most suitable model relating chlorophyll-α concentration and simulated TM/Landsat reflectance. TM4_sim/TM3_sim ratio provided the best model with a R2 value of 0.78. The model was then inverted to create a look-up-table (LUT relating TM4_sim/TM3_sim ratio intervals to chlorophyll-α concentration trophic state classes covering the entire range measured in the reservoir. Atmospheric corrected Landsat TM images converted to surface reflectance were then used to generate a TM4/TM3 ratio image. The ratio image frequency distribution encompassed the range of TM4_sim/TM3_sim ratio indicating agreement between in situ and satellite data and supporting the use of satellite data to map chlorophyll- concentration trophic state distribution in the reservoir. Based on that, the LUT was applied to a Landsat/TM ratio image to map the spatial distribution of chlorophyll- trophic state classes in Ibitinga reservoir. Despite the stochastic selection of TM4_sim/TM3_sim ratio as the best input variable for modeling the chlorophyll-α concentration, it has a physical basis: high concentration of phytoplankton increases the reflectance in the near-infrared (TM4 and decreases the reflectance in the red (TM3. The band ratio, therefore, enhances the relationship between chlorophyll- concentration and remotely sensed reflectance.

    Full Text Available Against the background of increased levels of interest in space and images beyond the field of geography, this article (re- introduces earlier work on the semiotics of maps undertaken by geographers in the 1960s. The data limitations, purpose and cultural context in which a user interprets a map's codes and conventions are highlighted in this work, which remains relevant to the interpretation of maps—new and old—forty years later. By means of drawing on geography's contribution to the semiotics of maps, the article goes on to examine the concept of urban social divisions as represented in map images. Using a small number of map images, including two of the most widely known maps of urban social division in Europe and North America, the roles of context, data and purpose in the production and interpretation of maps are discussed. By presenting the examples chronologically the article shows that although advances in data collection and manipulation have allowed researchers to combine different social variables in maps of social division, and to interact with map images, work by geographers on the semiotics of maps is no less relevant today than when it was first proposed forty years ago.

    To provide the first systematic analysis of a national (Wales) sample of free-text comments from patients with cancer, to determine emerging themes and insights regarding experiences of cancer care in Wales. Thematic analysis of free-text data from a population-based survey. Adult patients with a confirmed cancer diagnosis treated within a 3-month period during 2012 in the 7 health boards and 1 trust providing cancer care in Wales. Free-text categorised by theme, coded as positive or negative, with ratios. Overarching themes are identified incorporating comment categories. 4672 respondents (of n=7352 survey respondents) provided free-text comments. Data were coded using a multistage approach: (1) coding of comments into general categories (eg, nursing, surgery, etc), (2) coding of subcategories within main categories (eg, nursing care, nursing communication, etc), (3) cross-sectional analysis to identify themes cutting across categories, (4) mapping of categories/subcategories to corresponding closed questions in the Wales Cancer Patient Experience Survey (WCPES) data for comparison. Most free-text respondents (82%, n 3818) provided positive comments about their cancer care, with 49% (n=2313) giving a negative comment (ratio 0.6:1, negative-to-positive). 3172 respondents (67.9% of free-text respondents) provided a comment mapping to 1 of 4 overarching themes: communication (n=1673, 35.8% free-text respondents, a ratio of 1.0:1); waiting during the treatment and/or post-treatment phase (n=923, 19.8%, ratio 1.5:1); staffing and resource levels (n=671, 14.4% ratio 5.3:1); speed and quality of diagnostic care (n=374, 8.0%, ratio 1.5:1). Within these areas, constituent subthemes are discussed. This study presents specific areas of concern for patients with cancer, and reveals a number of themes present across the cancer journey. While the majority of comments were positive, analysis reveals concerns shared by significant numbers of respondents. Timely communication can

    2017-07-01

    Full Text Available Mapping soil texture in a river basin is critically important for eco-hydrological studies and water resource management at the watershed scale. However, due to the scarcity of in situ observation of soil texture, it is very difficult to map the soil texture in high resolution using traditional methods. Here, we used an integrated method based on fuzzy logic theory and data fusion to map the soil texture in the Heihe River basin in an arid region of Northwest China, by combining in situ soil texture measurement data, environmental factors, a previous soil texture map, and other thematic maps. Considering the different landscape characteristics over the whole Heihe River basin, different mapping schemes have been used to extract the soil texture in the upstream, middle, and downstream areas of the Heihe River basin, respectively. The validation results indicate that the soil texture map achieved an accuracy of 69% for test data from the midstream area of the Heihe River basin, which represents a much higher accuracy than that of another existing soil map in the Heihe River basin. In addition, compared with the time-consuming and expensive traditional soil mapping method, this new method could ensure greater efficiency and a better representation of the explicitly spatial distribution of soil texture and can, therefore, satisfy the requirements of regional modeling.

    The increasing availability of satellite data is a real value for the enhancement of environmental knowledge and land management. Possibilities to integrate different source of geo-data are growing and methodologies to create thematic database are becoming very sophisticated. Moreover, the access to internet services and, in particular, to web mapping services is well developed and spread either between expert users than the citizens. Web map services, like Google Maps or Open Street Maps, give the access to updated optical imagery or topographic maps but information on land cover/use - are not still provided. Therefore, there are many failings in the general utilization -non-specialized users- and access to those maps. This issue is particularly felt where the digital (web) maps could form the basis for land use management as they are more economic and accessible than the paper maps. These conditions are well known in many African countries where, while the internet access is becoming open to all, the local map agencies and their products are not widespread.

    To thematically synthesise primary qualitative studies of the barriers, motivators and enablers of smoke-free homes (SFHs). Systematic review and thematic synthesis. Searches of MEDLINE, EBM Reviews (Cochrane Database of Systematic Reviews), PsycINFO, Global Health, CINAHL, Web of Science, Informit and EMBASE, combining terms for families, households and vulnerable populations; SFH and secondhand smoke; and qualitative research, were supplemented by searches of PhD theses, key authors, specialist journals and reference lists. We included 22 articles, reporting on 18 studies, involving 646 participants. peer-reviewed; English language; published from 1990 onwards (to week 3 of April 2014); used qualitative data collection methods; explored participants' perspectives of home smoking behaviours; and the barriers, motivators and enablers to initiating and/or maintaining a SFH. 1 of 3 authors extracted data with checking by a second. A thematic synthesis was performed to develop 7 core analytic themes: (1) knowledge, awareness and risk perception; (2) agency and personal skills/attributes; (3) wider community norms and personal moral responsibilities; (4) social relationships and influence of others; (5) perceived benefits, preferences and priorities; (6) addiction and habit; (7) practicalities. This synthesis highlights the complexity faced by many households in having a SFH, the practical, social, cultural and personal issues that need to be addressed and balanced by households, and that while some of these are common across study settings, specific social and cultural factors play a critical role in shaping household smoking behaviours. The findings can inform policy and practice and the development of interventions aimed at increasing SFHs. CRD42014014115. Published by the BMJ Publishing Group Limited.

    Nine adults who had completed an exercise referral scheme participated in a semi-structured interview to uncover the key psychological factors associated with adherence to the scheme. Through thematic analysis, an exercise identity emerged to be a major factor associated with adherence to the scheme, which was formed of a number of underpinning constructs including changes in self-esteem, changes in self-efficacy and changes in self-regulatory strategies. Also, an additional theme of transitions in motivation to exercise was identified, showing participants' motivation to alter from extrinsic to intrinsic reasons to exercise during the scheme.

    Cartography is one of the most important communication channels between users of spatial information and laymen as well as the open public alike. This applies to all known real-world objects located either here on Earth or on any other object in our Solar System. In planetary sciences, however, the main use of cartography resides in a concept called planetary mapping with all its various attached meanings: it can be (1) systematic spacecraft observation from orbit, i.e. the retrieval of physical information, (2) the interpretation of discrete planetary surface units and their abstraction, or it can be (3) planetary cartography sensu strictu, i.e., the technical and artistic creation of map products. As the concept of planetary mapping covers a wide range of different information and knowledge levels, aims associated with the concept of mapping consequently range from a technical and engineering focus to a scientific distillation process. Among others, scientific centers focusing on planetary cartography are the United State Geological Survey (USGS, Flagstaff), the Moscow State University of Geodesy and Cartography (MIIGAiK, Moscow), Eötvös Loránd University (ELTE, Hungary), and the German Aerospace Center (DLR, Berlin). The International Astronomical Union (IAU), the Commission Planetary Cartography within International Cartographic Association (ICA), the Open Geospatial Consortium (OGC), the WG IV/8 Planetary Mapping and Spatial Databases within International Society for Photogrammetry and Remote Sensing (ISPRS) and a range of other institutions contribute on definition frameworks in planetary cartography. Classical cartography is nowadays often (mis-)understood as a tool mainly rather than a scientific discipline and an art of communication. Consequently, concepts of information systems, mapping tools and cartographic frameworks are used interchangeably, and cartographic workflows and visualization of spatial information in thematic maps have often been

    Many children consume more sugar than is recommended, and caregivers often find it difficult to change this habit once established. This thematic synthesis aims to identify the "critical situations" where caregivers may be more likely to offer infants sugary drinks and snacks. This thematic synthesis is reported in accordance with the statement for enhancing transparency in reporting the synthesis of qualitative research (ENTREQ). Our confidence in the findings of our synthesis was assessed using the CERQual (Confidence in the Evidence From Reviews of Qualitative Research Approach). We included 16 studies from the United States, the United Kingdom, Australia, and Denmark. We identified eight "critical situations" when caregivers may be more likely to offer sugary drinks and snacks to infants. Interventions that seek to reduce sugar intake for caries prevention in infants and young children may be more successful if they provide caregivers with practical parenting strategies to replace the nonnutritive functions of sugary foods and drinks, as opposed to taking an information-giving approach. © The Author(s) 2016.

    Individuals representing various surgical disciplines have expressed concerns with the impact of resident duty hours (RDH) restrictions on resident education and patient outcomes. This thematic review of published viewpoints aimed to describe the effects of these restrictions in surgery. The authors conducted a qualitative systematic review of non-research-based literature published between 2003 and 2015. Articles were included if they focused on the RDH restrictions in surgery and resident wellness, health promotion, resident safety, resident education and/or training, patient safety, medical errors, and/or heterogeneity regarding training or disciplines. A thematic analysis approach guided data extraction. Contextual data were abstracted from the included articles to aid in framing the identified themes. Of 1,482 identified articles, 214 were included in the review. Most were from authors in the United States (144; 67%) and focused on the 80-hour workweek (164; 77%). The emerging themes were organized into three overarching categories: (1) impact of the RDH restrictions, (2) surgery has its own unique culture, and (3) strategies going forward. Published opinions suggested that RDH restrictions alone are insufficient to achieve the desired outcomes and that careful consideration of the surgical training model is needed to maintain the integrity of educational outcomes. Opinions from the surgical community highlight the complexity of issues surrounding the RDH restrictions and suggest that recent changes are not achieving all the desired outcomes and have resulted in unintended outcomes. From the perceptions of the various stakeholders in surgical education studied, areas for new policies were identified.

    Studies of psychotherapeutic treatments for nightmares have yielded support for their effectiveness. However, no consensus exists to explain how they work. This study combines a systematic review with a qualitative thematic analysis to identify and categorize the existing proposed mechanisms of action (MAs) of nightmare treatments. The systematic review allowed for a great number of scholarly publications on supported psychological treatments for nightmares to be identified. Characteristics of the study and citations regarding potential MAs were extracted using a standardized coding grid. Then, thematic analysis allowed citations to be grouped under six different categories of possible MAs according to their similarities and differences. Results reveal that an increased sense of mastery was the most often cited hypothesis to explain the efficacy of nightmare psychotherapies. Other mechanisms included emotional processing leading to modification of the fear structure, modification of beliefs, restoration of sleep functions, decreased arousal, and prevention of avoidance. An illustration of the different variables involved in the treatment of nightmares is proposed. Different avenues for operationalization of these MAs are put forth to enable future research on nightmare treatments to measure and link them to efficacy measures, and test the implications of the illustration.

    We conducted a scoping review of tools designed to add structure to clinical teaching, with a thematic analysis to establish definitional clarity. Six thousand and forty nine citations were screened, 434 reviewed for eligibility, and 230 identified as meeting study inclusion criteria. Eighty-nine names and 51 definitions were identified. Based on a post facto thematic analysis, we propose that these tools be named "deliberate teaching tools" (DTTs) and defined as "frameworks that enable clinicians to have a purposeful and considered approach to teaching encounters by incorporating elements identified with good teaching practice." We identified 46 DTTs in the literature, with 38 (82.6%) originally described for the medical setting. Forty justification articles consisted of 16 feedback surveys, 13 controlled trials, seven pre-post intervention studies with no control group, and four observation studies. Current evidence of efficacy is not entirely conclusive, and many studies contain methodology flaws. Forty-nine clarification articles comprised 12 systematic reviews and 37 narrative reviews. The most number of DTTs described by any review was four. A common design theme was identified in approximately three-quarters of DTTs. Applicability of DTTs to specific alternate settings should be considered in context, and appropriately designed justification studies are warranted to demonstrate efficacy.

    The British Psychological Society proposes that clinical psychologists are well placed to move beyond psychiatric diagnoses and develop alternative practices. This study sought to explore what the application of these guiding principles looks like in clinical practice, the challenges faced and possible routes forward. A purpose-designed survey was completed by 305 respondents and a thematic analysis completed. Thematic analysis was used to identify five superordinate themes relating to individuals, relational, others, structures and society, comprising of a total of 21 group themes. The presented group themes highlight an array of approaches to practicing beyond diagnosis and factors that help and hinder such action; from scaffolding change, becoming leaders, relating to the multi-disciplinary team, restructuring services and the processes of change. A key concept was "playing the diagnostic game". "Playing the diagnostic game" enables psychologists to manage an array of tensions and anxieties: conflicts between belief and practice, relationships with colleagues, and dilemmas of position and power. It also potentially limits a concerted questioning of diagnosis and consideration of alternatives. An alternative conceptual framework for non-diagnostic practice is needed to aid the collective efforts of clinical psychologists developing their practice beyond diagnosis, some of which have been highlighted in this study. Until then, ways of mitigating the perceived threats to questioning diagnosis need further exploration, theorising and backing.

    To explore the concept of sustainability in nursing using social media as a vehicle for discussion on the topic. There is a need for an increased awareness among nurses of the issues that are crucial for the healthcare sector to prepare for climate change and contribute to sustainable development. However, topics about sustainability and climate change are not a requirement of nursing curricula in Europe; social media provides an opportunity to raise issues and promote discussion. A thematic analysis of a Twitter discussion. A Twitter discussion session hosted by @WeNurses took place on 24 March 2015 over 1 hour. Data were gathered via this online discussion hosted on Twitter, a social media platform. Following the discussion a thematic analysis of the posted Tweets was conducted. One hundred and nineteen people posted nine hundred and ninety six Tweets, a reach of 3,306,368. Tweets broadly followed the questions posted by the team. Several threads related to the sustainable use of healthcare resources and the need to reduce waste was evident. A Word Cloud of the Tweets highlighted prominent words in the discussion: sustainability, nursing/nurses, curriculum, important, waste, practice, resources, student, plastic, health, gloves. Social media is an effective way of engaging nurses and students in a discussion on challenging issues. Sustainability appears to be important for nurses, with a particular emphasis on resource use and the importance of sustainability topics in nurse education. © 2016 John Wiley & Sons Ltd.

    Behaviour change is key to increasing the uptake of evidence into healthcare practice. Designing behaviour-change interventions first requires problem analysis, ideally informed by theory. Yet the large number of partly overlapping theories of behaviour makes it difficult to select the most appropriate theory. The need for an overarching theoretical framework of behaviour change was addressed in research in which 128 explanatory constructs from 33 theories of behaviour were identified and grouped. The resulting Theoretical Domains Framework (TDF) appears to be a helpful basis for investigating implementation problems. Research groups in several countries have conducted TDF-based studies. It seems timely to bring together the experience of these teams in a thematic series to demonstrate further applications and to report key developments. This overview article describes the TDF, provides a brief critique of the framework, and introduces this thematic series.In a brief review to assess the extent of TDF-based research, we identified 133 papers that cite the framework. Of these, 17 used the TDF as the basis for empirical studies to explore health professionals' behaviour. The identified papers provide evidence of the impact of the TDF on implementation research. Two major strengths of the framework are its theoretical coverage and its capacity to elicit beliefs that could signify key mediators of behaviour change. The TDF provides a useful conceptual basis for assessing implementation problems, designing interventions to enhance healthcare practice, and understanding behaviour-change processes. We discuss limitations and research challenges and introduce papers in this series.
