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.

1985-01-01

The Modulation Transfer Function (MTF) for thematic mapping (TM) bands 3, 4, 5 and 7 is reliably estimated with the San Mateo Bridge target in the 12/31/82 scene. These results are to be compared with those from the 8/12/83 scene. Bands 1, 2 and 6 are to be analyzed with a different target possessing greater contrast. This may be possible with the underflight data comparison currently underway. The registration of this data to the TM image of 8/12/83 for a region arround the Stockton sewage pond east of San Francisco has begun. This particular approach has the advantage that the full two-dimensional MFT will be measured instead of the MFT in only one azimuth as reported.

Ken-Betwa river link is one of the pilot projects of the Inter Linking of Rivers program of Government of India in Bundelkhand Region. It will connect the Ken and Betwa rivers through a system of dams, reservoirs, and canals to provide storage for excess rainfall during the monsoon season and avoid floods. The main objective of this study is to identify erosional and inundation prone zones of Ken-Betwa river linking site in India using remote sensing and geographic information system tools. In this study, Landsat Thematic Mapper data of year 2005, digital elevation model from the Shuttle Radar Topographic Mission, and other ancillary data were analyzed to create various thematic maps viz. geomorphology, land use/land cover, NDVI, geology, soil, drainage density, elevation, slope, and rainfall. The integrated thematic maps were used for hazard zonation. This is based on categorizing the different hydrological and geomorphological processes influencing the inundation and erosion intensity. Result shows that the southern part of the study area which lies in Panna district of Madhya Pradesh, India, is more vulnerable than the other areas.

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.

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.

The Rorschach Performance Assessment System (R-PAS) aims to provide an evidence-based approach to administration, coding, and interpretation of the Rorschach Inkblot Method (RIM). R-PAS analyzes individualized communications given by respondents to each card to code a wide pool of possible variables. Due to the large number of possible codes that can be assigned to these responses, it is important to consider the concordance rates among different assessors. This study investigated interrater reliability for R-PAS protocols. Data were analyzed from a nonpatient convenience sample of 50 participants who were recruited through networking, local marketing, and advertising efforts from January 2013 through October 2014. Blind recoding was used and discrepancies between the initial and blind coders' ratings were analyzed for each variable with SPSS yielding percent agreement and intraclass correlation values. Data for Location, Space, Contents, Synthesis, Vague, Pairs, Form Quality, Populars, Determinants, and Cognitive and Thematic codes are presented. Rates of agreement for 1,168 responses were higher for more simplistic coding (e.g., Location), whereas agreement was lower for more complex codes (e.g., Cognitive and Thematic codes). Overall, concordance rates achieved good to excellent agreement. Results suggest R-PAS is an effective method with high interrater reliability supporting its empirical basis.

In order to better determine the effects of the television imagery characteristics upon the interpretation of geographic patterns obtainable from orbital television sensors, and in order to better evaluate the influences of alternative sensor system parameters such as changes in orbital altitudes or scan line rates, a team of three professional interpreters independently mapped thematically the selected geographic phenomena that they could detect in orbital television imagery produced on a fourteen inch monitor and recorded photographically for analysis. Three thematic maps were compiled by each interpreter. The maps were: (1) transportation patterns; (2) other land use; and (3) physical regions. The results from the three interpreters are compared, agreements noted, and differences analyzed for cause such as disagreement on identification of phenomenon, visual acuity, differences in interpretation techniques, and differing professional backgrounds.

Landsat-4 Thematic Mapper and Multispectral Scanner 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 numerous supervised classifiers on data from Iowa and Illinois. A detailed spectral class analysis (multispectral classification) was carried out on data from the Des Moines, IA area to compare the information content of the MSS and TM for a large number of scene classes.

2018-01-01

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 to share health information, and approximately 38% (32/85) of the posts announcing research activities also included content to share health information. Finally, we found similarities and differences between the sampled hospitals in terms of the types of content they posted more frequently on their Facebook pages. Conclusions Hospitals use Facebook as an inexpensive way to educate people on health and wellness topics and to communicate different types of information and news to the public audience. Hospitals and clinics that are expanding their social media activities or are starting to embark on social media strategies can use the results of this study to better formulate their activities on Facebook.

The author has identified the following significant results. Skylab/EREP S190A and S190B film products were optically enhanced and visually interpreted to extract data suitable for mapping coastal land use; inventorying wetlands vegetation; monitoring tidal conditions; observing suspended sediment patterns; charting surface currents; locating coastal fronts and water mass boundaries; monitoring industrial and municipal waste dumps in the ocean; and determining the size and flow direction of river, bay, and man-made discharge plumes. Film products were visually analyzed to identify and map ten land use and vegetation categories at a scale of 1:125,000. Thematic maps were compared with CARETS land use maps, resulting in classification accuracies of 50 to 98%. Digital tapes from S192 were used to prepare thematic land use maps. The resolutions of the S190A, S190B, and S192 systems were 20-40m, 10-20m, and 70-100m, respectively.

Written accounts of living with epilepsy: A thematic analysis.

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.

1981-01-01

A set of training statistics for the 30 meter resolution simulated thematic mapper MSS data was generated based on land use/land cover classes. In addition to this supervised data set, a nonsupervised multicluster block of training statistics is being defined in order to compare the classification results and evaluate the effect of the different training selection methods on classification performance. Two test data sets, defined using a stratified sampling procedure incorporating a grid system with dimensions of 50 lines by 50 columns, and another set based on an analyst supervised set of test fields were used to evaluate the classifications of the TMS data. The supervised training data set generated training statistics, and a per point Gaussian maximum likelihood classification of the 1979 TMS data was obtained. The August 1980 MSS data was radiometrically adjusted. The SAR data was redigitized and the SAR imagery was qualitatively analyzed.

The use of thematic mapper data for land cover discrimination: Preliminary results from the UK SATMaP programme

1983-01-01

The principal objectives of the UK SATMaP program are to determine thematic mapper (TM) performance with particular reference to spatial resolution properties and geometric characteristics of the data. So far, analysis is restricted to images from the U.S. and concentrates on spectra and radiometric properties. The results indicate that the data are inherently three dimensional compared with the two dimensional character of MSS data. Preliminary classification results indicate the importance of the near infrared band (TM 4), at least one middle infrared band (TM 5 or TM 6) and at least one of the visible bands (preferably either TM 3 or TM 1). The thermal infrared also appears to have discriminatory ability despite its coarser spatial resolution. For band 4 the forward and reverse scans show somewhat different spectral responses in one scene but this effect is absent in the other analyzed. From examination of the histograms it would appear that the full 8-bit quantization is not being effectively utilized for all the bands.

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.

1984-01-01

Aircraft thematic mapper (TM) data were analyzed to evaluate the potential utility of the Landsat-4 thematic mapper for geologic mapping and detection of hydrothermal alteration zones in the Silver Bell porphyry copper deposit in southern Arizona. The data allow a comparison between aircraft TV simulator data and the Landsat-4 TM satellite data which possess similar spectral bands. A color rationcomposite of 30-m pixels was resampled, in order to clearly define a number of hydroxyl bearing minerals, (kaolinite, sericite, white mica), pyrite and iron oxide/hydroxide minerals. The iron oxide minerals have diagnostic absorption bands in the 0.45 and 0.85 micron regions of the spectrum, and the hydrous minerals are characterized by an absorption in the 2.2 micron region. The position of the spectral bands allow the TM to identify regions of hydrothermal alteration without resorting to a data processing algorithm. The comparison of the aircraft and Landsat-4 TM data showed considerable agreement, and confirmed the utility of TM data for identifying hydrothermal alteration zones. Samples of some color TM images are provided.

Damage to temporo-parietal cortex decreases incidental activation of thematic relations during spoken word comprehension

Mirman, Daniel; Graziano, Kristen M.

2012-01-01

Both taxonomic and thematic semantic relations have been studied extensively in behavioral studies and there is an emerging consensus that the anterior temporal lobe plays a particularly important role in the representation and processing of taxonomic relations, but the neural basis of thematic semantics is less clear. We used eye tracking to examine incidental activation of taxonomic and thematic relations during spoken word comprehension in participants with aphasia. Three groups of participants were tested: neurologically intact control participants (N=14), individuals with aphasia resulting from lesions in left hemisphere BA 39 and surrounding temporo-parietal cortex regions (N=7), and individuals with the same degree of aphasia severity and semantic impairment and anterior left hemisphere lesions (primarily inferior frontal gyrus and anterior temporal lobe) that spared BA 39 (N=6). The posterior lesion group showed reduced and delayed activation of thematic relations, but not taxonomic relations. In contrast, the anterior lesion group exhibited longer-lasting activation of taxonomic relations and did not differ from control participants in terms of activation of thematic relations. These results suggest that taxonomic and thematic semantic knowledge are functionally and neuroanatomically distinct, with the temporo-parietal cortex playing a particularly important role in thematic semantics.

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.

Background: Currently with the emergence of the Internet, patients have an opportunity to exchange social support online. However, little attention has been devoted to different dimensions of online social support exchanged in virtual support communities for patients with multiple sclerosis (MS). Methods: To provide a rich insight, the aim of this qualitative study was to explore and categorize different dimensions of online social support in messages exchanged in a virtual support community for patients with MS. A total of 548 posted messages created during one year period were selected using purposive sampling to consider the maximum variation sampling. Prior-research-driven thematic analysis was then conducted. In this regard, we used the Cutruna and Suhr’s coding system. The messages that could not be categorized with the used coding system were thematically analyzed to explore new additional social support themes. Results: The results showed that various forms of social support including informational, emotional, network, esteem and tangible support were exchanged. Moreover, new additional social support themes including sharing personal experiences, sharing coping strategies and spiritual support emerged in this virtual support community. Conclusion: The wide range of online social support exchanged in the virtual support community can be regarded as a supplementary source of social support for patients with MS. Future researches can examine online social support more comprehensively considering additional social support themes emerging in the present study. PMID:27382585

ENED-GEM: A Conceptual Framework Model for Psychological Enjoyment Factors and Learning Mechanisms in Educational Games about the Environment.

2017-01-01

Based on a thorough review of psychological literature, this article seeks to develop a model of game enjoyment and environmental learning (ENvironmental EDucational Game Enjoyment Model, ENED-GEM) and delineate psychological processes that might facilitate learning and inspire behavioral change from educational games about the environment. A critically acclaimed digital educational game about environmental issues (Fate of the World by Red Redemption/Soothsayer Games) was used as a case study. Two hundred forty-nine reviews of the game from the popular gaming and reviewing platform known as Steam were analyzed by means of a thematic content analysis in order to identify key player enjoyment factors believed to be relevant to the process of learning from games, as well as to gain an understanding of positive and negative impressions about the game's general content. The end results of the thematic analysis were measured up to the suggested ENED-GEM framework. Initial results generally support the main elements of the ENED-GEM, and future research into the importance of these individual core factors is outlined.

A critically acclaimed digital educational game about environmental issues (Fate of the World by Red Redemption/Soothsayer Games) was used as a case study. Two hundred forty-nine reviews of the game from the popular gaming and reviewing platform known as Steam were analyzed by means of a thematic content analysis in order to identify key player enjoyment factors believed to be relevant to the process of learning from games, as well as to gain an understanding of positive and negative impressions about the game’s general content. The end results of the thematic analysis were measured up to the suggested ENED-GEM framework. Initial results generally support the main elements of the ENED-GEM, and future research into the importance of these individual core factors is outlined. PMID:28701988

In an attempt to improve the land cover/use classification accuracy obtainable from remotely sensed multispectral imagery, Airborne Imaging Spectrometer-1 (AIS-1) images were analyzed in conjunction with Thematic Mapper Simulator (NS001) Large Format Camera color infrared photography and black and white aerial photography. Specific portions of the combined data set were registered and used for classification. Following this procedure, the resulting derived data was tested using an overall accuracy assessment method. Precise photogrammetric 2D-3D-2D geometric modeling techniques is not the basis for this study. Instead, the discussion exposes resultant spectral findings from the image-to-image registrations. Problems associated with the AIS-1 TMS integration are considered, and useful applications of the imagery combination are presented. More advanced methodologies for imagery integration are needed if multisystem data sets are to be utilized fully. Nevertheless, research, described herein, provides a formulation for future Earth Observation Station related multisensor studies.

Individual differences in the strength of taxonomic versus thematic relations

PubMed Central

Mirman, Daniel; Graziano, Kristen M.

2011-01-01

Knowledge about word and object meanings can be organized taxonomically (fruits, mammals, etc.) based on shared features, or thematically (eating breakfast, taking a dog for a walk, etc.) based on participation in events or scenarios. An eye-tracking study showed that both kinds of knowledge are activated during comprehension of a single spoken word, even when the listener is not required to perform any active task. The results further revealed that an individual’s relative activation of taxonomic relations compared to thematic relations predicts that individual’s tendency to favor taxonomic over thematic relations when asked to choose between them in a similarity judgment task. These results argue that individuals differ in the relative strengths of their taxonomic and thematic semantic knowledge and suggest that meaning information is organized in two parallel, complementary semantic systems.

A stochastic spatial computer model addressing coastal resource problems in Lousiana is being refined and validated using thematic mapper (TM) imagery. The TM images of brackish marsh sites were processed and data were tabulated on spatial parameters from TM images of the salt marsh sites. The Fisheries Image Processing Systems (FIPS) was used to analyze the TM scene. Activities were concentrated on improving the structure of the model and developing a structure and methodology for calibrating the model with spatial-pattern data from the TM imagery.

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. This analysis describes an informal curriculum that is diverse in themes. Student narratives suggest their clinical experiences to be influential on professionalism development. Medical students focus on different aspects of professionalism depending on clerkship specialty.

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. PMID:28428766

Surveillance of compliance with tobacco regulations in Örebro County, Sweden: a mixed methods study after the ban of test purchases

PubMed Central

2012-01-01

Background Tobacco has long been known to be one of the most common reasons for sickness and premature deaths in the world. An important aspect of tobacco use is the youth's access to tobacco, and surveillance visits are one way to make sure how retailers are complying with age limit in the tobacco law. In Örebro County, Sweden, a project to reinforce the tobacco legislation was carried out in 2009-2010. One part of the project was surveillance visits that were done according to three different themes, called thematic surveillance. Methods This study is an evaluation of the results from thematic surveillance and has a mixed methods approach. The quantitative analyses concerns protocols from 217 surveillance visits, where questions were asked about three themes (self-monitoring programs; marketing; labeling of products and pricing). In addition, questionnaires filled out by six tobacco administrators who worked within the project were analyzed qualitatively by content analysis in order to study their perceptions and opinions of the project. Results This study shows that half of the visited retailers had self-monitoring programs. Lack of self-monitoring programs was significantly more common in smaller stores/kiosks and at restaurants. Further, the tobacco administrators who worked within the project perceived thematic surveillance as a good method for accomplishing better structure in surveillance work, but not as effective as purchase attempts (mystery shopping). Conclusions Thematic surveillance was perceived as positive and the method was also regarded to be a good way to work with surveillance. However, the method could be developed further for optimal use and better effect at the retailers. It is clear that people who work with tobacco prevention at the local level in Örebro County want to use purchase attempts as a surveillance method, and that they believe that purchase attempts is the best way to make sure if store comply with the tobacco law.

The dynamics of human-induced land cover change in miombo ecosystems of southern Africa

NASA Astrophysics Data System (ADS)

Jaiteh, Malanding Sambou

Understanding human-induced land cover change in the miombo require the consistent, geographically-referenced, data on temporal land cover characteristics as well as biophysical and socioeconomic drivers of land use, the major cause of land cover change. The overall goal of this research to examine the applications of high-resolution satellite remote sensing data in studying the dynamics of human-induced land cover change in the miombo. Specific objectives are to: (1) evaluate the applications of computer-assisted classification of Landsat Thematic Mapper (TM) data for land cover mapping in the miombo and (2) analyze spatial and temporal patterns of landscape change locations in the miombo. Stepwise Thematic Classification, STC (a hybrid supervised-unsupervised classification) procedure for classifying Landsat TM data was developed and tested using Landsat TM data. Classification accuracy results were compared to those from supervised and unsupervised classification. The STC provided the highest classification accuracy i.e., 83.9% correspondence between classified and referenced data compared to 44.2% and 34.5% for unsupervised and supervised classification respectively. Improvements in the classification process can be attributed to thematic stratification of the image data into spectrally homogenous (thematic) groups and step-by-step classification of the groups using supervised or unsupervised classification techniques. Supervised classification failed to classify 18% of the scene evidence that training data used did not adequately represent all of the variability in the data. Application of the procedure in drier miombo produced overall classification accuracy of 63%. This is much lower than that of wetter miombo. The results clearly demonstrate that digital classification of Landsat TM can be successfully implemented in the miombo without intensive fieldwork. Spatial characteristics of land cover change in agricultural and forested landscapes in central Malawi were analyzed for the period 1984 to 1995 spatial pattern analysis methods. Shifting cultivation areas, Agriculture in forested landscape, experienced highest rate of woodland cover fragmentation with mean patch size of closed woodland cover decreasing from 20ha to 7.5ha. Permanent bare (cropland and settlement) in intensive agricultural matrix landscapes increased 52% largely through the conversion of fallow areas. Protected National Park area remained fairly unchanged although closed woodland area increased by 4%, mainly from regeneration of open woodland. This study provided evidence that changes in spatial characteristics in the miombo differ with landscape. Land use change (i.e. conversion to cropland) is the primary driving force behind changes in landscape spatial patterns. Also, results revealed that exclusion of intense human use (i.e. cultivation and woodcutting) through regulations and/or fencing increased both closed woodland area (through regeneration of open woodland) and overall connectivity in the landscape. Spatial characteristics of land cover change were analyzed at locations in Malawi (wetter miombo) and Zimbabwe (drier miombo). Results indicate land cover dynamics differ both between and within case study sites. In communal areas in the Kasungu scene, land cover change is dominated by woodland fragmentation to open vegetation. Change in private commercial lands was dominantly expansion of bare (settlement and cropland) areas primarily at the expense of open vegetation (fallow land).

To analyze the Final Report of the VIII Health Conference and the São José dos Pinhais City Health Program for 2010-2013 and investigate whether these documents addressed the themes of sustainability, governance, and equity and the interfaces between these themes--government policies, power balance, and inclusive processes/impacting results--that make up the Concept Model for Human Development and Health Promotion developed by the authors. This case study analyzed 331 proposals approved for incorporation in the City Health Program. The six thematical categories of the Concept Model were analyzed using ATLAS Ti 5.0 software. The proposals were classified according to the number of themes and interfaces of the Concept Model: full health proposals contained all six categories; partial proposals contained three categories; and incipient proposals contained one category. Of 331 proposals approved, 162 (49%) contemplated the six thematical categories and were classified as full health promotion proposals. Ninety-five (29%) contemplated three categories (partial health promotion). Of these, 38 (12%) addressed Governance, Sustainability, and Government Policies, 33 (10%) addressed Governance, Power Balance, and Equity and 24 (7%) addressed Equity, Inclusive Processes/Impact Results, and Sustainability. Finally, 74 (22%) proposals contemplated only one category and were classified as incipient: 36 (11%) addressed Governance, 27 (8%) addressed sustainability, and 11 (3%) addressed equity. Based on the fact that 49% of the proposals approved were classified as full health promotion, it is considered that the effectiveness of social control and popular participation in the construction of health policies at the local level contritute to the promotion of health in the city.

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.

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.

Being Subject to Restrictions, Limitations and Disciplining: A Thematic Analysis of Individuals' Experiences in Psychiatric Intensive Care.

2017-07-01

The aim of this study was to describe individuals' experiences of being hospitalized in psychiatric intensive care units (PICUs). Four participants who had previously been admitted in a PICU were interviewed using open-ended questions. The data were analyzed using thematic analysis. Analysis resulted in a synthesis of the various ways patients experienced limitations: (1) Descriptions of Being Limited in the Environment, (2) Descriptions of being Limited in Interactions with Staff, (3) Descriptions of Being Limited in terms of Access to Information, and (4) Descriptions of Having Limited Freedom and Autonomy. Hospitalization is experienced as a life-changing event that shows a kaleidoscopic view of limitation. We stress that the conceptualization of limitation must be considered due to its historical origins, sociopolitical aspirations, and philosophy of care. Thus, nurse practitioners and nursing leaders are advised to put the patient's experience at the center of care, and to involve and integrate patients throughout the recovery process.

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.

The Relation between Thematic Role Computing and Semantic Relatedness Processing during On-Line Sentence Comprehension

Sentence comprehension involves timely computing different types of relations between its verbs and noun arguments, such as morphosyntactic, semantic, and thematic relations. Here, we used EEG technique to investigate the potential differences in thematic role computing and lexical-semantic relatedness processing during on-line sentence comprehension, and the interaction between these two types of processes. Mandarin Chinese sentences were used as materials. The basic structure of those sentences is “Noun+Verb+‘le’+a two-character word”, with the Noun being the initial argument. The verb disambiguates the initial argument as an agent or a patient. Meanwhile, the initial argument and the verb are highly or lowly semantically related. The ERPs at the verbs revealed that: relative to the agent condition, the patient condition evoked a larger N400 only when the argument and verb were lowly semantically related; however, relative to the high-relatedness condition, the low-relatedness condition elicited a larger N400 regardless of the thematic relation; although both thematic role variation and semantic relatedness variation elicited N400 effects, the N400 effect elicited by the former was broadly distributed and reached maximum over the frontal electrodes, and the N400 effect elicited by the latter had a posterior distribution. In addition, the brain oscillations results showed that, although thematic role variation (patient vs. agent) induced power decreases around the beta frequency band (15–30 Hz), semantic relatedness variation (low-relatedness vs. high-relatedness) induced power increases in the theta frequency band (4–7 Hz). These results suggested that, in the sentence context, thematic role computing is modulated by the semantic relatedness between the verb and its argument; semantic relatedness processing, however, is in some degree independent from the thematic relations. Moreover, our results indicated that, during on-line sentence comprehension, thematic role computing and semantic relatedness processing are mediated by distinct neural systems. PMID:24755643

Currently with the emergence of the Internet, patients have an opportunity to exchange social support online. However, little attention has been devoted to different dimensions of online social support exchanged in virtual support communities for patients with multiple sclerosis (MS). To provide a rich insight, the aim of this qualitative study was to explore and categorize different dimensions of online social support in messages exchanged in a virtual support community for patients with MS. A total of 548 posted messages created during one year period were selected using purposive sampling to consider the maximum variation sampling. Prior-research-driven thematic analysis was then conducted. In this regard, we used the Cutruna and Suhr's coding system. The messages that could not be categorized with the used coding system were thematically analyzed to explore new additional social support themes. The results showed that various forms of social support including informational, emotional, network, esteem and tangible support were exchanged. Moreover, new additional social support themes including sharing personal experiences, sharing coping strategies and spiritual support emerged in this virtual support community. The wide range of online social support exchanged in the virtual support community can be regarded as a supplementary source of social support for patients with MS. Future researches can examine online social support more comprehensively considering additional social support themes emerging in the present study.

Analyzing thematic maps and mapping for accuracy

Rosenfield, G.H.

1982-01-01

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 either the row totals or the column totals from the original classification error matrices. In hypothesis testing, when the results of tests of multiple sample cases prove to be significant, some form of statistical test must be used to separate any results that differ significantly from the others. In the past, many analyses of the data in this error matrix were made by comparing the relative magnitudes of the percentage of correct classifications, for either individual categories, the entire map or both. More rigorous analyses have used data transformations and (or) two-way classification analysis of variance. A more sophisticated step of data analysis techniques would be to use the entire classification error matrices using the methods of discrete multivariate analysis or of multiviariate analysis of variance.

Contrasting Semantic versus Inhibitory Processing in the Angular Gyrus: An fMRI Study.

PubMed

Lewis, Gwyneth A; Poeppel, David; Murphy, Gregory L

2018-06-06

Recent studies of semantic memory have focused on dissociating the neural bases of two foundational components of human thought: taxonomic categories, which group similar objects like dogs and seals based on features, and thematic categories, which group dissimilar objects like dogs and leashes based on events. While there is emerging consensus that taxonomic concepts are represented in the anterior temporal lobe, there is disagreement over whether thematic concepts are represented in the angular gyrus (AG). We previously found AG sensitivity to both kinds of concepts; however, some accounts suggest that such activity reflects inhibition of irrelevant information rather than thematic activation. To test these possibilities, an fMRI experiment investigated both types of conceptual relations in the AG during two semantic judgment tasks. Each task trained participants to give negative responses (inhibition) or positive responses (activation) to word pairs based on taxonomic and thematic criteria of relatedness. Results showed AG engagement during both negative judgments and thematic judgments, but not during positive judgments about taxonomic pairs. Together, the results suggest that activity in the AG reflects functions that include both thematic (but not taxonomic) processing and inhibiting irrelevant semantic information.

2012-08-01

We present an automated web server for partial order optimum likelihood (POOL), a machine learning application that combines computed electrostatic and geometric information for high-performance prediction of catalytic residues from 3D structures. Input features consist of THEMATICS electrostatics data and pocket information from ConCavity. THEMATICS measures deviation from typical, sigmoidal titration behavior to identify functionally important residues and ConCavity identifies binding pockets by analyzing the surface geometry of protein structures. Both THEMATICS and ConCavity (structure only) do not require the query protein to have any sequence or structure similarity to other proteins. Hence, POOL is applicable to proteins with novel folds and engineered proteins. As an additional option for cases where sequence homologues are available, users can include evolutionary information from INTREPID for enhanced accuracy in site prediction. The web site is free and open to all users with no login requirements at http://www.pool.neu.edu. m.ondrechen@neu.edu Supplementary data are available at Bioinformatics online.

The first product of the Optimizing Design and Management of Protected Areas for Conservation Project is a land cover change detection analysis based on Landsat thematic mapper (TM) and enhanced thematic mapper plus (ETM+) imagery collected at intervals between 1989 and 2002. The goal of this analysis was to quantify and analyze patterns of forest clearing, land conversion, and other disturbances in and around the Cordillera Azul National Park in Peru. After removing clouds and cloud shadows from the imagery using a series of automatic and manual processes, a Tasseled Cap Transformation was used to detect pixels of high reflectance, which were classified as bare ground and areas of likely forest clearing. Results showed a slow but steady increase in cleared ground prior to 1999 and a rapid and increasing conversion rate after that time. The highest concentrations of clearings have spread upward from the western border of the study area on the Huallaga River. To date, most disturbances have taken place in the buffer zone around the park, not within it, but the data show dense clearings occurring closer to the park border each year.

Abstract Objective To conduct a thematic analysis of the College of Family Physicians of Canada’s (CFPC’s) Red Book accreditation standards and the Triple C Competency-based Curriculum objectives with respect to patient safety principles. Design Thematic content analysis of the CFPC’s Red Book accreditation standards and the Triple C curriculum. Setting Canada. Main outcome measures Coding frequency of the patient safety principles (ie, patient engagement; respectful, transparent relationships; complex systems; a just and trusting culture; responsibility and accountability for actions; and continuous learning and improvement) found in the analyzed CFPC documents. Results Within the analyzed CFPC documents, the most commonly found patient safety principle was patient engagement (n = 51 coding references); the least commonly found patient safety principles were a just and trusting culture (n = 5 coding references) and complex systems (n = 5 coding references). Other patient safety principles that were uncommon included responsibility and accountability for actions (n = 7 coding references) and continuous learning and improvement (n = 12 coding references). Conclusion Explicit inclusion of patient safety content such as the use of patient safety principles is needed for residency training programs across Canada to ensure the full spectrum of care is addressed, from community-based care to acute hospital-based care. This will ensure a patient safety culture can be cultivated from residency and sustained into primary care practice. PMID:27965349

Exploring Hospitals' Use of Facebook: Thematic Analysis.

Kordzadeh, Nima; Young, Diana K

2018-05-16

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. 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. 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%). 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 to share health information, and approximately 38% (32/85) of the posts announcing research activities also included content to share health information. Finally, we found similarities and differences between the sampled hospitals in terms of the types of content they posted more frequently on their Facebook pages. Hospitals use Facebook as an inexpensive way to educate people on health and wellness topics and to communicate different types of information and news to the public audience. Hospitals and clinics that are expanding their social media activities or are starting to embark on social media strategies can use the results of this study to better formulate their activities on Facebook. ©Nima Kordzadeh, Diana K Young.

Johnson, R. H.; Shah, N. J.; Schmidt, N. F.

1975-01-01

The investigation and results of the Thematic Mapper Instrument Performance Study are described. The Thematic Mapper is the advanced multispectral scanner initially planned for the Earth Observation Satellite and now planned for LANDSAT D. The use of existing digital airborne scanner data obtained with the Modular Multispectral Scanner (M2S) at Bendix provided an opportunity to simulate the effects of variation of design parameters of the Thematic Mapper. Analysis and processing of this data on the Bendix Multispectral Data Analysis System were used to empirically determine categorization performance on data generated with variations of the sampling period and scan overlap parameters of the Thematic Mapper. The Bendix M2S data, with a 2.5 milliradian instantaneous field of view and a spatial resolution (pixel size) of 10-m from 13,000 ft altitude, allowed a direct simulation of Thematic Mapper data with a 30-m resolution. The flight data chosen were obtained on 30 June 1973 over agricultural test sites in Indiana.

Objective This study examined knowledge, access, utilization, and barriers to use of resources among Black women exposed to multiple types of intimate partner violence in Baltimore, Maryland and the U.S. Virgin Islands (USVI). Methods We analyzed quantitative survey data collected by 163 women recruited from primary care, prenatal or family planning clinics in Baltimore and the USVI. In addition we analyzed qualitative data from in-depth interviews with 11 women. Quantitative data were analyzed using descriptive statistics and qualitative data were analyzed using thematic analysis. Results A substantial proportion of Black women with multiple types of violence experiences lacked knowledge of, did not have access to, and did not use resources. Barriers to resource use were identified at the individual, relationship, and community levels. Conclusion There is need for programs to develop awareness, promote access and utilization of resources, and eliminate barriers to resource use among abused Black women. PMID:26548679

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.

Pettigrew, Simone; Archer, Catherine; Harrigan, Paul

2016-05-01

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.

Buzás, György Miklós

2010-01-01

AIM: To analyze the contribution of Orvosi Hetilap (Hungarian Medical Journal) to the field of gastroenterology. METHODS: All issues of the journal between 1857 and 2008 and identified original articles and reviews dealing with gastroenterology were reviewed. The rate of publications, the thematic distribution and foreign sources of knowledge were assessed. The dates that major achievements in gastroenterology were introduced in Hungary were compared to those dates in Western medicine. RESULTS: A total of 4799 original/research articles on gastroenterology were published, which represents 11.1% of the total publications. Thematic rankings showed that liver and biliary diseases represented 20.36% of the total, followed by gastric diseases (9.35%) and surgery (8.77%). A total of 268 foreign journals were reviewed: 50.9% were German, 30.4% English, 12.1% French and only 6.6% were in other languages. The major achievements of gastroenterology were introduced with varying delays compared to Western countries. CONCLUSION: Orvosi Hetilap has made a large contribution to the development of Hungarian gastroenterology. The high proportion of gastroenterology studies underlines the importance of digestive diseases in public health. PMID:20458774

Objective To explore attitudes toward physical activity of White midlife women in the United States using a feminist perspective. Design A cross-sectional qualitative study using a thematic analysis. Setting Internet communities for midlife women. Participants Twenty-nine White midlife women in the United States recruited using a convenience sampling method. Methods We used 17 topics on attitudes toward physical activity and ethnic-specific contexts to administer an online forum. We analyzed the data using thematic analysis. Results We found three themes: “thinking without action”; “gendered and sedentary culture”; and “motivating myself.” The women knew and understood the necessity of physical activity for their physical and mental health but in most cases had not been able to take action to increase their physical activities. Although the culture that circumscribed the women's physical activity was sedentary in nature, the women tried to motivate themselves to increase their physical activities through several creative strategies. Conclusion The findings strongly suggest that although women were doing their best, American culture itself needs to be changed to help women increase physical activity in their daily lives.

2009-01-01

As scientists and decision makers increasingly rely on multiple Earth-observing satellites to address urgent global issues, it is imperative that they can rely on the accuracy of Earth-observing data products. This paper focuses on the crosscomparison of the Indian Remote Sensing (IRS-P6) Advanced Wide Field Sensor (AWiFS) with the Landsat 5 (L5) Thematic Mapper (TM), Landsat 7 (L7) Enhanced Thematic Mapper Plus (ETM+), and Terra Moderate Resolution Imaging Spectroradiometer (MODIS) sensors. The cross-comparison was performed using image statistics based on large common areas observed by the sensors within 30 minutes. Because of the limited availability of simultaneous observations between the AWiFS and the Landsat and MODIS sensors, only a few images were analyzed. These initial results are presented. Regression curves and coefficients of determination for the top-of-atmosphere (TOA) trends from these sensors were generated to quantify the uncertainty in these relationships and to provide an assessment of the calibration differences between these sensors. ?? 2009 SPIE.

Schölin, Lisa; Eriksson, Charli

2012-02-15

Tobacco has long been known to be one of the most common reasons for sickness and premature deaths in the world. An important aspect of tobacco use is the youth's access to tobacco, and surveillance visits are one way to make sure how retailers are complying with age limit in the tobacco law. In Örebro County, Sweden, a project to reinforce the tobacco legislation was carried out in 2009-2010. One part of the project was surveillance visits that were done according to three different themes, called thematic surveillance. This study is an evaluation of the results from thematic surveillance and has a mixed methods approach. The quantitative analyses concerns protocols from 217 surveillance visits, where questions were asked about three themes (self-monitoring programs; marketing; labeling of products and pricing). In addition, questionnaires filled out by six tobacco administrators who worked within the project were analyzed qualitatively by content analysis in order to study their perceptions and opinions of the project. This study shows that half of the visited retailers had self-monitoring programs. Lack of self-monitoring programs was significantly more common in smaller stores/kiosks and at restaurants. Further, the tobacco administrators who worked within the project perceived thematic surveillance as a good method for accomplishing better structure in surveillance work, but not as effective as purchase attempts (mystery shopping). Thematic surveillance was perceived as positive and the method was also regarded to be a good way to work with surveillance. However, the method could be developed further for optimal use and better effect at the retailers. It is clear that people who work with tobacco prevention at the local level in Örebro County want to use purchase attempts as a surveillance method, and that they believe that purchase attempts is the best way to make sure if store comply with the tobacco law.

Limited research takes a socio-biographical approach to study the experiences and perspectives of individuals affected by Alzheimer's disease and related dementias. The purpose of this study was to thematically analyze blog narratives written by people with Alzheimer's disease and related dementia and care partners in order to increase understanding of their experiences. Nineteen blogs written by people with Alzheimer's disease and related dementia and 44 blogs written by care partners were analyzed. The first two authors utilized line-by-line open coding to analyze five posts from each group for the development of a codebook. Using NVivo software, the first author proceeded to code the remaining blogs for emergent themes and subcategories. Emergent themes included (1) effects of Alzheimer's disease and related dementia on the person with Alzheimer's disease and related dementia and/or the care partner; (2) seeing the positives; (3) feeling out of control; (4) advocacy and empowerment; (5) coping mechanisms and compensatory strategies; and (6) candid descriptions of experiences with Alzheimer's disease and related dementia. These themes also encompassed numerous subcategories that are discussed in this paper. Results from this study provide insights into the experiences of individuals affected by Alzheimer's disease and related dementia. Writers discussed several topics that are consistent with research on illness narratives of individuals with chronic diseases, including loss of identity, strategies for coping, and poignant descriptions of life with the disease. This study provides information in the form of overlapping themes from first-person perspectives of numerous individuals affected by Alzheimer's disease and related dementia. This type of data is crucial to understand the experiences of people who live with ADRD.

1984-01-01

An experiment of a factorial design was conducted to test the effects on classification accuracy of land cover types due to the improved spatial, spectral and radiometric characteristics of the Thematic Mapper (TM) in comparison to the Multispectral Scanner (MSS). High altitude aircraft scanner data from the Airborne Thematic Mapper instrument was acquired over central California in August, 1983 and used to simulate Thematic Mapper data as well as all combinations of the three characteristics for eight data sets in all. Results for the training sites (field center pixels) showed better classification accuracies for MSS spatial resolution, TM spectral bands and TM radiometry in order of importance.

Solar thematic maps for space weather operations

Rigler, E. Joshua; Hill, Steven M.; Reinard, Alysha A.; Steenburgh, Robert A.

2012-01-01

Thematic maps are arrays of labels, or "themes", associated with discrete locations in space and time. Borrowing heavily from the terrestrial remote sensing discipline, a numerical technique based on Bayes' theorem captures operational expertise in the form of trained theme statistics, then uses this to automatically assign labels to solar image pixels. Ultimately, regular thematic maps of the solar corona will be generated from high-cadence, high-resolution SUVI images, the solar ultraviolet imager slated to fly on NOAA's next-generation GOES-R series of satellites starting ~2016. These thematic maps will not only provide quicker, more consistent synoptic views of the sun for space weather forecasters, but digital thematic pixel masks (e.g., coronal hole, active region, flare, etc.), necessary for a new generation of operational solar data products, will be generated. This paper presents the mathematical underpinnings of our thematic mapper, as well as some practical algorithmic considerations. Then, using images from the Solar Dynamics Observatory (SDO) Advanced Imaging Array (AIA) as test data, it presents results from validation experiments designed to ascertain the robustness of the technique with respect to differing expert opinions and changing solar conditions.

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 (TM) data are being used to refine and validate a stochastic spatial computer model to be applied to coastal resource management problems in Louisiana. Two major aspects of the research are: (1) the measurement of area of land (or emergent vegetation) and water and the length of the interface between land and water in TM imagery of selected coastal wetlands (sample marshes); and (2) the comparison of spatial patterns of land and water in the sample marshes of the imagery to that in marshes simulated by a computer model. In addition to activities in these two areas, the potential use of a published autocorrelation statistic is analyzed.

Aim Medical students’ perceptions of professionalism might reflect the impact of the current educational processes on their professional identity development. This study focuses on Ankara University Faculty of Medicine students’ perceptions of ‘good doctor’ along with the factors effective on the formation of these perceptions. Method Six focus groups with 59 medical students from Grade-1 and Grade-6 were held. The transcripts of discussions were analyzed thematically. Results Results regarding ‘being a good physician’ mostly mirrored the findings of previous studies framing the medical professionalism concept. The thematic pattern of the discussions on the relation between professional development and medical education suggests that students suffer from a gradual erosion of perception during medical education. That the education cannot either change the person for the better or might downgrade the person instead of improving her/him were shared by participants from both grades. Students consider clinical practice and role models two main variables determining the person's qualification as a professional. Conclusions The formal and hidden programs determine the quality and efficacy of the professional education together. Attempts to restructure medical education must recognize the reciprocal dynamics between these two components and, thus, should carefully work out the practical aspect of the educational processes.

2017-01-01

ABSTRACT Objective: To analyze pediatricians’ representations on the nutritional alternatives that are adopted when weaning becomes inevitable. Methods: This is a mixed cross-sectional analytical study with probabilistic sampling. Fifty-seven randomly selected pediatricians were interviewed with the use of a semi-structured script for thematic analysis. The technique of free evocations was used, and the terms were processed using software EVOC 2005. The thematic categories were established on software NVivo10, and their co-occurrence matrix was exported and analyzed in terms of their simple similarity hierarchy on software CHIC. Results: In the pediatricians’ representations, whole milk was cited as a foodstuff with high allergenic risk (35.1%) and nutritionally inappropriate, and they did not recommend its use if weaning occurred before 1 year of age. The infant formula, referred by 98.3% of the pediatricians as the best alternative at the moment of weaning, was cited by 38.1% of them owing to its nutritional adequacy. The points quoted as unfavorable to the use of the formula were the price, the possibility of causing allergy and the risk of the inadequate use of such a highly industrialized product. Conclusions: The pediatricians’ representations show that they are sensitive to the importance of breast-feeding and at the same time, to the sociocultural difficulties inherent in the practice. Generally speaking, the interviewed pediatricians recommend the use of milk formulas, and not of whole cow’s milk, if weaning occurs before the end of the first year of life. PMID:28977316

ABSTRACT OBJECTIVE This study aims to analyze the association between the incidence of tuberculosis and different socioeconomic indicators in a territory of intense transformation of the urban space. METHODS This is an ecological study, whose analysis units were the neighborhoods of the city of Itaboraí, state of Rio de Janeiro, Brazil. The data have been analyzed by generalized linear models. The response variable was incidence of tuberculosis from 2006 to 2011. The independent variables were the socio-demographic indicators. The spatial distribution of tuberculosis was analyzed with the elaboration of thematic maps. RESULTS The results have shown a significant association between the incidence of tuberculosis and variables that reflect different dimensions of living conditions, such as consumer goods, housing conditions and its surroundings, agglomeration of population, and income distribution. CONCLUSIONS The disproportionate incidence of tuberculosis in populations with worse living conditions highlights the persistence of socioeconomic determinants in the reproduction of the disease. Different municipal public sectors need to better articulate with local tuberculosis control programs to reduce the social burden of the disease. PMID:28225909

A Thematic Analysis of Online Discussion Boards for Vasectomy.

PubMed

Samplaski, Mary K

2018-01-01

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.

Not Your Same Old Story: New Rules for Thematic Apperceptive Techniques (TATs).

PubMed

Jenkins, Sharon Rae

2017-01-01

Stories told about pictures have been used for both research and clinical practice since the beginning of modern personality assessment. However, with the growing science-practice gap, these thematic apperceptive techniques (TATs) have been used differently in those 2 venues. Scientific validation is presumptively general, but clinical application is idiographic and situation-specific. A bridge is needed. The manualized human-scored narrative analysis systems discussed here are valuable scientist-practitioner tools, but they require a validation literature to support further research publication, maintain their role in clinical training, and justify clinicians' reimbursement by third-party payers. To facilitate wider understanding of manualized TAT methodologies, this article addresses long-standing criticisms of TAT reliability and proposes some strategic solutions to the measurement error problem for both researchers and clinicians, including analyzing person-situation interactions, purposeful situation sampling for within-storyteller comparisons, and uses of small samples. The new rules for TATs include conceptual and methodological standards that researchers should aim to meet and report, reviewers should apply to manuscripts, and clinical assessors can use to analyze their own data and justify third-party payment.

Ribeiro, Moneda Oliveira

2003-01-01

The paper focuses on the child in a street situation, through the address by a group of school-age children who used to frequent two public São Paulo city shelters. The purpose was to apprehend its representation on its reality. The data, gathered by means of interviews, were organized and analyzed according to the method of the Analysis of Contents. The thematic theories detached from the speech transcript were grouped into meaningful experiences for the children, among which "the street". The synthesis of the analyzed categories showed clearly that violence permeates the lives of children of/in the street, resulting in experiences that restrict their full development. The street represents a refuge to the child coming from a needy family and also to the one who has a history of abuse from its family.

A Combination of Thematic and Similarity-Based Semantic Processes Confers Resistance to Deficit Following Left Hemisphere Stroke

PubMed Central

Kalénine, Solène; Mirman, Daniel; Buxbaum, Laurel J.

2012-01-01

Semantic knowledge may be organized in terms of similarity relations based on shared features and/or complementary relations based on co-occurrence in events. Thus, relationships between manipulable objects such as tools may be defined by their functional properties (what the objects are used for) or thematic properties (e.g., what the objects are used with or on). A recent study from our laboratory used eye-tracking to examine incidental activation of semantic relations in a word–picture matching task and found relatively early activation of thematic relations (e.g., broom–dustpan), later activation of general functional relations (e.g., broom–sponge), and an intermediate pattern for specific functional relations (e.g., broom–vacuum cleaner). Combined with other recent studies, these results suggest that there are distinct semantic systems for thematic and similarity-based knowledge and that the “specific function” condition drew on both systems. This predicts that left hemisphere stroke that damages either system (but not both) may spare specific function processing. The present experiment tested these hypotheses using the same experimental paradigm with participants with left hemisphere lesions (N = 17). The results revealed that, compared to neurologically intact controls (N = 12), stroke participants showed later activation of thematic and general function relations, but activation of specific function relations was spared and was significantly earlier for stroke participants than controls. Across the stroke participants, activation of thematic and general function relations was negatively correlated, further suggesting that damage tended to affect either one semantic system or the other. These results support the distinction between similarity-based and complementarity-based semantic relations and suggest that relations that draw on both systems are relatively more robust to damage.

The Neural Bases of Taxonomic and Thematic Conceptual Relations: An MEG Study

PubMed Central

Lewis, Gwyneth A.; Poeppel, David; Murphy, Gregory L.

2015-01-01

Converging evidence from behavioral and neuroimaging studies of human concepts indicate distinct neural systems for taxonomic and thematic knowledge. A recent study of naming in aphasia found involvement of the anterior temporal lobe (ATL) during taxonomic (feature-based) processing, and involvement of the temporoparietal junction (TPJ) during thematic (function-based) processing. We conducted an online magnetoencephalography (MEG) study to examine the spatio-temporal nature of taxonomic and thematic relations. We measured participants’ brain responses to words preceded by either a taxonomically or thematically related item (e.g., cottage→castle, king→castle). In a separate experiment we collected relatedness ratings of the word pairs from participants. We examined effects of relatedness and relation type on activation in ATL and TPJ regions of interest (ROIs) using permutation t-tests to identify differences in ROI activation between conditions as well as single-trial correlational analyses to examine the millisecond-by-millisecond influence of the stimulus variables on the ROIs. Taxonomic relations strongly predicted ATL activation, and both kinds of relations influenced the TPJ. Our results further strengthen the view of the ATL's importance to taxonomic knowledge. Moreover, they provide a nuanced view of thematic relations as involving taxonomic knowledge. PMID:25582406

Impact of action primes on implicit processing of thematic and functional similarity relations: evidence from eye-tracking.

Pluciennicka, Ewa; Wamain, Yannick; Coello, Yann; Kalénine, Solène

2016-07-01

The aim of this study was to specify the role of action representations in thematic and functional similarity relations between manipulable artifact objects. Recent behavioral and neurophysiological evidence indicates that while they are all relevant for manipulable artifact concepts, semantic relations based on thematic (e.g., saw-wood), specific function similarity (e.g., saw-axe), and general function similarity (e.g., saw-knife) are differently processed, and may relate to different levels of action representation. Point-light displays of object-related actions previously encoded at the gesture level (e.g., "sawing") or at the higher level of action representation (e.g., "cutting") were used as primes before participants identified target objects (e.g., saw) among semantically related and unrelated distractors (e.g., wood, feather, piano). Analysis of eye movements on the different objects during target identification informed about the amplitude and the timing of implicit activation of the different semantic relations. Results showed that action prime encoding impacted the processing of thematic relations, but not that of functional similarity relations. Semantic competition with thematic distractors was greater and earlier following action primes encoded at the gesture level compared to action primes encoded at higher level. As a whole, these findings highlight the direct influence of action representations on thematic relation processing, and suggest that thematic relations involve gesture-level representations rather than intention-level representations.

To determine whether there is a gap between what patients know about early-stage prostate cancer and what they need to know to make treatment decisions, and whether the information patients receive varies depending on their treating physician. Needs assessment was performed using a questionnaire consisting of 41 statements about early-stage prostate cancer. Statements were divided into six thematic subsets. Participants used a 5-point Likert scale to rate statements in terms of knowledge of the information and importance to a treatment decision. Information gaps were defined as significant difference between the importance and knowledge of an item. Descriptive statistics were used to describe demographic subscale scores. The information gap was analyzed by a paired t test for each thematic subset. One-way analyses of variance were used to detect any differences on the basis of treating physician. Questionnaires were distributed to 270 men (135 treated by radical prostatectomy, 135 by external beam radiotherapy). The return rate was 51% (138 questionnaires). A statistically significant information gap was found among all six thematic subsets, with five of the six P values less than 0.0001. Statistically significant variation was observed in the amount of information patients received from their treating physicians among four of the thematic subsets. There is an information gap between what early-stage prostate cancer patients need to know and the information they receive. Additionally there is a difference in the amount of information provided by different physicians.

The purpose of this study is to explore the impact of an educational documentary, MY MASCULINITY HELPS ( MMH), as a sexual violence prevention tool. MMH is a short (i.e., 31 min) educational documentary that explores the role of African American men and boys in the prevention of sexual violence. Participants ( N = 88) completed an electronic, qualitative questionnaire after viewing the documentary and data collected were analyzed and interpreted using thematic analysis. Findings from the study highlighted the power of documentary film to impact knowledge, beliefs, social norms related to masculinity and the role of African American men as allies, empowerment, and commitment to action. Implications of MMH as a prosocial bystander behavior intervention and educational tool are discussed.

The Language of Ageism: Why We Need to Use Words Carefully.

PubMed

Gendron, Tracey L; Welleford, E Ayn; Inker, Jennifer; White, John T

2016-12-01

Language carries and conveys meaning which feeds assumptions and judgments that can lead to the development of stereotypes and discrimination. As a result, this study closely examined the specific language that is used to communicate attitudes and perceptions of aging and older adults. We conducted a qualitative study of a twitter assignment for 236 students participating in a senior mentoring program. Three hundred fifty-four tweets were qualitatively analyzed to explore language-based age discrimination using a thematic analytic approach. Twelve percent of the tweets (n = 43) were found to contain discriminatory language. Thematic analysis of the biased tweets identified 8 broad themes describing language-based age discrimination: assumptions and judgments, older people as different, uncharacteristic characteristics, old as negative, young as positive, infantilization, internalized ageism, and internalized microaggression. The language of ageism is rooted in both explicit actions and implicit attitudes which make it highly complex and difficult to identify. Continued examination of linguistic encoding is needed in order to recognize and rectify language-based age discrimination. © The Author 2015.

Preliminary evaluation of the landsat-4 thematic mapper data for mineral exploration

USGS Publications Warehouse

Podwysocki, M.H.; Power, M.S.; Jones, O.D.

1985-01-01

Landsat-4 Thematic Mapper (TM) data recorded over an arid terrain were analyzed to determine the applicability of using of TM data for identifying and mapping hydrothermally altered, potentially mineralized rocks. Clays, micas, and other minerals bearing the OH anion in specific crystal lattice positions have absorption bands in the 2.2-??m region (TM channel 7, TM7) and commonly lack features in the 1.6-??m region (TM5). Channel ratios TM5/TM7, TM5/TM4, and TM3/TM1 were combined into a color-ratio-composite (CRC) image and used to distinguish hydrothermally altered rocks, unaltered rocks, and vegetation. These distinctions are made possible by using the TM5 and TM7, channels which are not available in the Landsat multispectral scanner (MSS). Digital masking was used to eliminate ambiguities due to water and shadows. However, some ambiguities in identification resulted between altered volcanic rocks and unaltered sedimentary deposits that contained clays, carbonates, and gypsum, and between altered volcanic rocks and volcanic tuffs diagenetically altered to zeolites. However, compared to MSS data, TM data should greatly improve the ability to map hydrothermally altered rocks in arid terrains. ?? 1985.

Fire effects in the northern Chihuahuan Desert derived from Landsat-5 Thematic Mapper spectral indices

NASA Astrophysics Data System (ADS)

White, Joseph D.; Swint, Pamela

2014-01-01

Fire effects on desert ecosystems may be long-lasting based on ecological impact of fire in these environments which potentially is detected from multispectral sensors. To assess this, we analyzed changes in spectral characteristics from 1986 to 2010 of pixels associated with the location of fires that occurred between 1986 and 1999 in Big Bend National Park, USA, located in the northern Chihuahuan Desert. Using Landsat-5 Thematic Mapper (TM) data, we derived spectral indices including the simple ratio (SR), normalized difference vegetation index (NDVI), soil-adjusted vegetation index (SAVI), and normalized burn ratio (NBR) from 1989, 1999, and 2010 from the TM data and compared changes in spectral index values for sites with and without observed fire. We found that the NDVI and SAVI had significantly different values over the time for burned sites of different fire sizes. When differences of the spectral indices were calculated from each time period, time since fire was correlated with the SR and NBR indices. These results showed that large fires potentially had a persistent and long-term change in vegetation cover and soil characteristics which were detected by the extraordinary long-data collection period of the Landsat-5 TM sensor.

Phenology of Succession: Tracking the Recovery of Dryland Forests after Wildfire Events

2016-12-01

The frequency, size, and intensity of forest wildfires in the U.S. Southwest have increased over the past 30 years. In the coming decades, burn effects and altered climatic conditions may increasingly divert vegetation recovery trajectories from pre-disturbance forested ecosystems toward grassland or shrub woodlands. Dryland herbaceous and woody vegetation species exhibit different phenological responses to precipitation, resulting in temporal and spatial shifts in landscape phenology patterns as the proportions of plant functional groups change over time. We have developed time series of Normalized Difference Vegetation Index (NDVI) and Soil-Adjusted Vegetation Index (SAVI) greenness measures derived from satellite imagery from 1984 - 2015 to record the phenological signatures that characterize recovery trajectories towards predominantly grassland, shrubland, or forest land cover types. We leveraged the data and computational resources available through the Google Earth Engine cloud-based platform to analyze time series of Landsat Thematic Mapper and Enhanced Thematic Mapper Plus imagery collected over maturing (40 years or more post-fire) dryland forests in Arizona and New Mexico, USA. These time series provided the basis for long-term comparisons of phenology behavior in different successional trajectories and enabled the assessment of climatic influence on the eventual outcomes.

Evaluation and interpretation of Thematic Mapper ratios in equations for estimating corn growth parameters

NASA Technical Reports Server (NTRS)

Dardner, B. R.; Blad, B. L.; Thompson, D. R.; Henderson, K. E.

1985-01-01

Reflectance and agronomic Thematic Mapper (TM) data were analyzed to determine possible data transformations for evaluating several plant parameters of corn. Three transformation forms were used: the ratio of two TM bands, logarithms of two-band ratios, and normalized differences of two bands. Normalized differences and logarithms of two-band ratios responsed similarly in the equations for estimating the plant growth parameters evaluated in this study. Two-term equations were required to obtain the maximum predictability of percent ground cover, canopy moisture content, and total wet phytomass. Standard error of estimate values were 15-26 percent lower for two-term estimates of these parameters than for one-term estimates. The terms log(TM4/TM2) and (TM4/TM5) produced the maximum predictability for leaf area and dry green leaf weight, respectively. The middle infrared bands TM5 and TM7 are essential for maximizing predictability for all measured plant parameters except leaf area index. The estimating models were evaluated over bare soil to discriminate between equations which are statistically similar. Qualitative interpretations of the resulting prediction equations are consistent with general agronomic and remote sensing theory.

This study set out to explore the experience of food cravings and thirst, and their management strategies in patients on hemodialysis. Semi-structured interviews with N = 32 hemodialysis patients were analyzed thematically. Findings indicated that food cravings and thirst were common in everyday life of patients and resulted in different emotional responses. A combination of cognitive and behavioral strategies was employed, including avoidance, controlled consumption, and substitution. Self-monitoring and compensatory strategies were also used to prevent or compensate for lapses. These findings lay the groundwork for future work aimed to improve adherence in end-stage renal disease patients. © The Author(s) 2014.

This qualitative phenomenological study explores the lived experiences of perceived support by Iranian mothers who have children with learning disability. Twelve open interviews with six mothers of learning-disabled children (7-12 years of age) were audiotape-recorded with participants' consent. The interviews were transcribed and data were analyzed using Van Manen methodology. Two major themes emerged from 138 thematic sentences. The mothers'experiences could be interpreted as a sense of being in the light or being in the shade of support, with variations for different participants. The results indicate a need for more specialized and individually adjusted support for mothers in Iran.

The effects of health promotion interventions are the result not only of the interventions themselves, but also of the contexts in which they unfold. The objective of this study was to analyze, through stakeholders' discourse, the characteristics of an intervention that can influence its outcomes. This case study was based on semi-structured interviews with health promotion stakeholders involved in a regional program (PRALIMAP). General hypotheses on transferability and on how the intervention is presumed to produce its effects were used to construct an interview guide. Interviews were analyzed using thematic coding. Twenty-three stakeholders were interviewed. Results showed stakeholders made few references to population and environment characteristics. Three themes emerged as significant for the stakeholders: implementation modalities and methodology, modalities used to mobilize actors; and transferability-promoting factors and barriers. Our work contributes to a better understanding not only of transferability factors, but also of stakeholders' perceptions of them, which are just as important, because those perceptions themselves are a factor in mobilization of actors, implementation, and transferability.

2018-01-01

Topic modeling algorithms are widely used to analyze the thematic composition of text corpora but remain difficult to interpret and adjust. Addressing these limitations, we present a modular visual analytics framework, tackling the understandability and adaptability of topic models through a user-driven reinforcement learning process which does not require a deep understanding of the underlying topic modeling algorithms. Given a document corpus, our approach initializes two algorithm configurations based on a parameter space analysis that enhances document separability. We abstract the model complexity in an interactive visual workspace for exploring the automatic matching results of two models, investigating topic summaries, analyzing parameter distributions, and reviewing documents. The main contribution of our work is an iterative decision-making technique in which users provide a document-based relevance feedback that allows the framework to converge to a user-endorsed topic distribution. We also report feedback from a two-stage study which shows that our technique results in topic model quality improvements on two independent measures.

This systematic literature review analyzed the construct of spirituality as perceived by people who have experienced or are experiencing a major life event or transition. The researchers investigated studies that used narrative analysis or a phenomenological methodology related to the topic. Thematic analysis resulted in three major themes: (1) avenues to and through spirituality, (2) the experience of spirituality, and (3) the meaning of spirituality. The results provide insights into the intersection of spirituality, meaning, and occupational engagement as understood by people experiencing a major life event or transition and suggest further research that addresses spirituality in occupational therapy and interdisciplinary intervention.

Extracting samples of high diversity from thematic collections of large gene banks using a genetic-distance based approach

PubMed Central

2010-01-01

Background Breeding programs are usually reluctant to evaluate and use germplasm accessions other than the elite materials belonging to their advanced populations. The concept of core collections has been proposed to facilitate the access of potential users to samples of small sizes, representative of the genetic variability contained within the gene pool of a specific crop. The eventual large size of a core collection perpetuates the problem it was originally proposed to solve. The present study suggests that, in addition to the classic core collection concept, thematic core collections should be also developed for a specific crop, composed of a limited number of accessions, with a manageable size. Results The thematic core collection obtained meets the minimum requirements for a core sample - maintenance of at least 80% of the allelic richness of the thematic collection, with, approximately, 15% of its size. The method was compared with other methodologies based on the M strategy, and also with a core collection generated by random sampling. Higher proportions of retained alleles (in a core collection of equal size) or similar proportions of retained alleles (in a core collection of smaller size) were detected in the two methods based on the M strategy compared to the proposed methodology. Core sub-collections constructed by different methods were compared regarding the increase or maintenance of phenotypic diversity. No change on phenotypic diversity was detected by measuring the trait "Weight of 100 Seeds", for the tested sampling methods. Effects on linkage disequilibrium between unlinked microsatellite loci, due to sampling, are discussed. Conclusions Building of a thematic core collection was here defined by prior selection of accessions which are diverse for the trait of interest, and then by pairwise genetic distances, estimated by DNA polymorphism analysis at molecular marker loci. The resulting thematic core collection potentially reflects the maximum allele richness with the smallest sample size from a larger thematic collection. As an example, we used the development of a thematic core collection for drought tolerance in rice. It is expected that such thematic collections increase the use of germplasm by breeding programs and facilitate the study of the traits under consideration. The definition of a core collection to study drought resistance is a valuable contribution towards the understanding of the genetic control and the physiological mechanisms involved in water use efficiency in plants.

Substance abusing mothers and their children are more likely to experience a range of social, behavioral, and psychological difficulties. Despite the significant challenges faced by these families, little is known about their experiences in treatment. The current study analyzed 12 sessions of family therapy using thematic analysis to identify common themes that arose during substance abusing mothers and their children's discussion during family therapy. Mothers' ages ranged from 28 to 35 years and the children's ages ranged from 12 to 14 years. Four therapy sessions from three families were coded for a total of 12 therapy sessions. An ecological framework was used to classify themes, in which themes related to each level of the families' ecological systems were identified. Thematic analysis of the therapy sessions indicated that mothers and their children primarily discussed topics related to their relational and emotional needs. The findings indicated that substance use disordered mothers and their children have unique treatment needs that should be addressed when the mother seeks treatment. More research is needed to further clarify and confirm the observations in this study. In particular, future research should include a larger sample and quantitative methodology.

Effects of Landsat 5 Thematic Mapper and Landsat 7 Enhanced Thematic Mapper plus radiometric and geometric calibrations and corrections on landscape characterization

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 radiometric normalization, the Normalized Difference Vegetation Index (NDVI) imagery and classification products of Landsats 5 and 7 were very similar. This implies that data from the two sensors can be used to measure and monitor the same landscape phenomena and that Landsats 5 and 7 data can be used interchangeably with proper caution. In addition, it was found that difference imagery produced using Landsat 7 ETM+ data are of excellent quality.

Methods for the thematic synthesis of qualitative research in systematic reviews

PubMed Central

Thomas, James; Harden, Angela

2008-01-01

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. Conclusion We compare thematic synthesis to other methods for the synthesis of qualitative research, discussing issues of context and rigour. Thematic synthesis is presented as a tried and tested method that preserves an explicit and transparent link between conclusions and the text of primary studies; as such it preserves principles that have traditionally been important to systematic reviewing.

This documentary, qualitative, descriptive study has the objective to analyze images and representations of the female body and their relation to drug use in the content of articles published in four magazines with national circulation (Veja, Isto E, Boa Forma, Claúdia). The articles selected were submitted to the technique of content analysis, with three thematic groups identified: the body as an incentive to use drugs; risks to the body resulting from drug use; and the search for the perfect body through drug use. The data showed that the media reproduces rigid aesthetic standards, exposing women to social and health offenses that stimulate drug use, either autonomously or by prescription. The search for beauty and the appeal to feminine eroticism, published through the communication channels analyzed limit the social importance of women by using images that link them to the status of sexual object.

To analyze the access and accessibility to the healthcare network of women dwelling in rural contexts undergoing violence situation, as seen from the professionals' speeches. A qualitative, exploratory, descriptive study with professionals from the healthcare network services about coping with violence in four municipalities in the northern region of Rio Grande do Sul. The information derived from interviews, which have been analyzed by thematic modality. (Lack of) information of women, distance, restricted access to transportation, dependence on the partner and (lack of) attention by professionals to welcome women undergoing violence situation and (non)-articulation of the network are factors that limit the access and, as a consequence, they result in the lack of confrontation of this problem. To bring closer the services which integrate the confrontation network of violence against women and to qualify professionals to welcome these situations are factors that can facilitate the access and adhesion of rural women to the services.

The aim of this study was to analyze nurses' experiences of role strain when taking care of patients with severe acute respiratory syndrome (SARS). We adopted an interpretive/ constructivist paradigm. Twenty-one nurses who had taken care of SARS patients were interviewed in focus groups. The data were analyzed using thematic analysis. The self-state of nurses during the SARS outbreak evolved into that of professional self as: (1) self-preservation; (2) self-mirroring; and (3) self-transcendence. The relationship between self-state and reflective practice is discussed.

LANDSAT thematic mapper P-data of Washington, D.C., Harrisburg, PA, and Salton Sea, CA were analyzed to determine magnitudes and causes of error in the geometric conformity of the data to known earth-surface geometry. Several tests of data geometry were performed. Intra-band and inter-band correlation and registration were investigated, exclusive of map-based ground truth. Specifically, the magnitudes and statistical trends of pixel offsets between a single band's mirror scans (due to processing procedures) were computed, and the inter-band integrity of registration was analyzed.

Moral hazards are the result of an expansive range of factors mostly originating in the patients' roles. The objective of the present study was to investigate patient incentives for moral hazards using the experiences of experts of basic Iranian insurance organizations. This was a qualitative research. Data were collected through semi-structured interviews. The study population included all experts of basic healthcare insurance agencies in the City of Isfahan, Iran, who were familiar with the topic of moral hazards. A total of 18 individuals were selected through purposive sampling and interviewed and some criteria such as data reliability and stability were considered. The anonymity of the interviewees was preserved. The data were transcribed, categorized, and then, analyzed through thematic analysis method. Through thematic analysis, 2 main themes and 11 subthemes were extracted. The main themes included economic causes and moral-cultural causes affecting the phenomenon of moral hazards resulted from patients' roles. Each of these themes has some sub-themes. False expectations from insurance companies are rooted in the moral and cultural values of individuals. People with the insurance coverage make no sense if using another person insurance identification or requesting physicians for prescribing the medicines. These expectations will lead them to moral hazards. Individuals with any insurance coverage should consider the rights of insurance agencies as third party payers and supportive organizations which disburden them from economical loads in the time of sickness.

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.

Niccum, Blake A; Sarker, Arnab; Wolf, Stephen J; Trowbridge, Matthew J

2017-01-01

ABSTRACT Background: 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. Objective: We aim to characterize I&E education in US allopathic medical schools to provide insight into the features and objectives of this growing field. Design: 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. Results: 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. Conclusions: 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.

Buchbinder, Mara; Timmermans, Stefan

2012-08-01

Positive newborn screening (NBS) results cause significant parental distress, but little is known about how parents find out about children's screening results and what they are told. This qualitative, exploratory study reports on parents' perceptions of the initial communication of NBS results. Participants included the parents of 75 infants referred to a metabolic clinic in California over a 3-year period (2007-2010). Parents provided information about the initial communication of NBS results during audiotaped clinical encounters and open-ended interviews. Transcripts were analyzed inductively using thematic coding. Responses fell into 3 primary themes: sources of news delivery, providing information, and mitigation strategies. The findings suggest that health care providers have access to a range of communicative resources to buffer the impact of positive screening results that may be mobilized in future interventions. Recommendations for improving the communication process and future research directions are discussed.

Analyze This! Thematic Analysis: Hostility, Attribution of Intent, and Interpersonal Perception Bias.

PubMed

Karadenizova, Zhana; Dahle, Klaus-Peter

2017-11-01

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.

A Thematic Analysis of Online Discussion Boards for Brachial Plexus Injury.

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.

Understanding the patterns of species richness and their environmental drivers, remains a central theme in ecological research and especially in the continental scales where many conservation decisions are made. Here, we analyzed the patterns of species richness from amphibians, reptiles and mammals at the EU level. We used two different data sources for each taxon: expert-drawn species range maps, and presence/absence atlases. As environmental drivers, we considered climate and land cover. Land cover is increasingly the focus of research, but there still is no consensus on how to classify land cover to distinct habitat classes, so we analyzed the CORINE land cover data with three different levels of thematic resolution (resolution of classification scheme ˗ less to more detailed). We found that the two types of species richness data explored in this study yielded different richness maps. Although, we expected expert-drawn range based estimates of species richness to exceed those from atlas data (due to the assumption that species are present in all locations throughout their region), we found that in many cases the opposite is true (the extreme case is the reptiles where more than half of the atlas based estimates were greater than the expert-drawn range based estimates). Also, we detected contrasting information on the richness drivers of biodiversity patterns depending on the dataset used. For atlas based richness estimates, landscape attributes played more important role than climate while for expert-drawn range based richness estimates climatic variables were more important (for the ectothermic amphibians and reptiles). Finally we found that the thematic resolution of the land cover classification scheme, also played a role in quantifying the effect of land cover diversity, with more detailed thematic resolution increasing the relative contribution of landscape attributes in predicting species richness.

2012-01-01

In a qualitative study employing an exploratory design, the researcher explored the perceptions of communication choice and usage among 14 African American hearing parents of deaf and hard of hearing children. Semistructured, in-depth thematic interviews were used with a modified grounded-theory approach in which themes were analyzed and coded. Four thematic challenges and opportunities related to communication choice and usage were found: (a) oral tradition-nommo, (b) sign and oral-diunital, (c) literacy, and (d) racial/ethnic cultural socialization. Afrocentric implications for deaf and hard of hearing children are explored based on research observations pertaining to the significance of the oral tradition in African American culture and the socialization of African American deaf and hard of hearing children in the context of African American hearing families.

1983-01-01

Data collected on the spectral characteristics of the LANDSAT-4 and LANDSAT-4 backup thematic mapper instruments, the protoflight (TM/PF) and flight (TM/F) models, respectively, are presented and analyzed. Tests were conducted on the instruments and their components to determine compliance with two sets of spectral specifications: band-by-band spectral coverage and channel-by-channel within-band spectral matching. Spectral coverage specifications were placed on: (1) band edges--points at 50% of peak response, (2) band edge slopes--steepness of rise and fall-off of response, (3) spectral flatness--evenness of response between edges, and (4) spurious system response--ratio of out-of-band response to in-band response. Compliance with the spectral coverage specifications was determined by analysis of spectral measurements on the individual components contributing to the overall spectral response: filters, detectors, and optical surfaces.

DISCRIMINATION OF ALTERED BASALTIC ROCKS IN THE SOUTHWESTERN UNITED STATES BY ANALYSIS OF LANDSAT THEMATIC MAPPER DATA.

USGS Publications Warehouse

Davis, Philip A.; Berlin, Graydon L.; Chavez, Pat S.

1987-01-01

Landsat Thematic Mapper image data were analyzed to determine their ability to discriminate red cone basalts from gray flow basalts and sedimentary country rocks for three volcanic fields in the southwestern United States. Analyses of all of the possible three-band combinations of the six nonthermal bands indicate that the combination of bands 1, 4, and 5 best discriminates among these materials. The color-composite image of these three bands unambiguously discriminates 89 percent of the mapped red volcanic cones in the three volcanic fields. Mineralogic and chemical analyses of collected samples indicate that discrimination is facilitated by the presence of hematite as a major mineral phase in the red cone basalts (hematite is only a minor mineral phase in the gray flow basalts and red sedimentary rocks).

Advances in perinatal mental health research have provided valuable insights around risk factors for the overall development of maternal distress. However, there is still a limited understanding of the experience of women struggling emotionally during pregnancy. We explored how women view, experience, and interpret psychological distress antenatally. Eighteen Australian women participated in in-depth interviews that were analyzed thematically within a critical realist theoretical framework. We present and situate the current findings within the dominant discourse of the good mother, which arguably promotes guilt and stigma and results in women self-labeling as bad mothers.

The mental health impact of abusive adolescent dating relationships has not been well described, but fear related to abuse has been reported. We elaborate the theme of fear in women's descriptions of a history of adolescent dating abuse. A sample of community-based women, ages 19-34, who experienced an abusive dating relationship during adolescence (ages 11-20) was used. Data were analyzed via thematic analysis. Fear was a consistent and resonant theme. Three types of fear were identified: fear for self, fear for other relationships, and fearful expectation. These results offer important insights into the impact of abusive adolescent relationships on women's mental health.

Aircraft simulated thematic mapper data and field data were acquired in the fall and spring to analyze the relationship of spectral response and biomass for the marsh grass Spartina patens. Regression results indicate no simple relationship exists for TMS spectral response and biomass with a high R sq. However, results show a consistent relationship between spectral response and the percent live vegetation (by weight) and percent interstitial standing surface water (by area) as independent variables. It is suggested that the reflected energy of a pixel represents a mixture of surface constituents. It is recommended that alternative remote sensors be employed to account for the pixel constituents of live and dead vegetation, litter, and standing water.

The discovery of anti-diabetic drugs is an active Chinese medicine research area. This study aims to map out anti-diabetic drug research in China using a network-based systemic approach based on co-authorship of academic publications. We focused on identifying leading knowledge production institutions, analyzing interactions among them, detecting communities with high internal associations, and exploring future research directions. Target articles published in 2009-2013 under the topic "diabetes" and subject category "pharmacology & pharmacy," with "China," "Taiwan," "Hong Kong," or "Macao" (or "Macau") in the authors' address field were retrieved from the science citation index expanded database and their bibliographic information (e.g., article title, authors, keywords, and authors' affiliation addresses) analyzed. A social network approach was used to construct an institutional collaboration network based on co-publications. Gephi software was used to visualize the network and relationships among institutes were analyzed using centrality measurements. Thematic analysis based on article keywords and R sc value was applied to reveal the research hotspots and directions of network communities. The top 50 institutions were identified; these included Shanghai Jiao Tong University, National Taiwan University, Peking University, and China Pharmaceutical University. Institutes from Taiwan tended to cooperate with institutes outside Taiwan, but those from mainland China showed low interest in external collaboration. Fourteen thematic communities were detected with the Louvain algorithm and further labeled by their high-frequency and characteristic keywords, such as Chinese medicines, diabetic complications, oxidative stress, pharmacokinetics, and insulin resistance. The keyword Chinese medicines comprised a range of Chinese medicine-related topics, including berberine, flavonoids, Astragalus polysaccharide, emodin, and ginsenoside. These keywords suggest potential fields for further anti-diabetic drug research. The correlation of -0.641 (P = 0.013) between degree centrality and the R sc value of non-core keywords indicates that communities concentrating on rare research fields are usually isolated by others and have a lower chance of collaboration. With a better understanding of the Chinese landscape in anti-diabetic drug research, researchers and scholars looking for experts and institutions in a specific research area can rapidly spot their target community, then select the most appropriate potential collaborator and suggest preferential research directions for future studies.

2014-01-01

Substance abusing mothers and their children are more likely to experience a range of social, behavioral, and psychological difficulties. Despite the significant challenges faced by these families, little is known about their experiences in treatment. The current study analyzed 12 sessions of family therapy using thematic analysis to identify common themes that arose during substance abusing mothers and their children’s discussion during family therapy. Mothers’ ages ranged from 28 to 35 years and the children’s ages ranged from 12 to 14 years. Four therapy sessions from three families were coded for a total of 12 therapy sessions. An ecological framework was used to classify themes, in which themes related to each level of the families’ ecological systems were identified. Thematic analysis of the therapy sessions indicated that mothers and their children primarily discussed topics related to their relational and emotional needs. The findings indicated that substance use disordered mothers and their children have unique treatment needs that should be addressed when the mother seeks treatment. More research is needed to further clarify and confirm the observations in this study. In particular, future research should include a larger sample and quantitative methodology. PMID:25729116

SUMMARY SETTING Patients who initiated treatment for multi-drug-resistant tuberculosis (MDR-TB) at 15 Programmatic Management of Drug-resistant Tuberculosis (PMDT) health facilities in the Philippines between July and December 2012. OBJECTIVES To describe patients’ views of current interventions, and suggest changes likely to reduce MDR-TB loss to follow-up. METHODS In-depth interviews were conducted between April and July 2014 with MDR-TB patients who were undergoing treatment, had finished treatment at the time of the interview (controls), or had been lost to follow-up (LTFU). Responses were thematically analyzed. RESULTS Interviews were conducted with 182 patients who were undergoing or had completed treatment and 91 LTFU patients. Views and suggestions could be thematically categorized as approaches to facilitate adherence or address barriers to adherence. The top themes were the need for transportation assistance or improvements to the current transportation assistance program, food assistance, and difficulties patients encountered related to their medications. These themes were addressed by respectively 63%, 60%, and 32% of the participants. CONCLUSIONS A more patient-centered approach is needed to improve MDR-TB treatment adherence. Programs should strive to provide assistance that considers patient preferences, is adequate to cover actual costs or needs, and is delivered in a timely, uninterrupted manner. PMID:28157461

Medical students' perceptions of professionalism might reflect the impact of the current educational processes on their professional identity development. This study focuses on Ankara University Faculty of Medicine students' perceptions of 'good doctor' along with the factors effective on the formation of these perceptions. Six focus groups with 59 medical students from Grade-1 and Grade-6 were held. The transcripts of discussions were analyzed thematically. Results regarding 'being a good physician' mostly mirrored the findings of previous studies framing the medical professionalism concept. The thematic pattern of the discussions on the relation between professional development and medical education suggests that students suffer from a gradual erosion of perception during medical education. That the education cannot either change the person for the better or might downgrade the person instead of improving her/him were shared by participants from both grades. Students consider clinical practice and role models two main variables determining the person's qualification as a professional. The formal and hidden programs determine the quality and efficacy of the professional education together. Attempts to restructure medical education must recognize the reciprocal dynamics between these two components and, thus, should carefully work out the practical aspect of the educational processes.

Commercial transplantation has expanded because of the shortage of kidneys for transplantation. This study aims to synthesize qualitative studies on the experiences and perspectives of living commercial kidney donors. We conducted a comprehensive literature search in electronic databases to April 2011 and consulted experts to identify unpublished studies. Thematic synthesis was used to analyze the findings. Seven studies involving over 676 commercial kidney donors were included. Three major themes were identified: desperation (the participants' decision to sell their kidney was forced by poverty, debt, or to fulfill a family obligation); despair (destroyed body integrity, shame and secrecy, dehumanized and dispirited, loss of livelihood, heightened sense of vulnerability, disappointment, and regret); and debasement (deception by brokers and recipients, victimized by the hospital, stigmatized by community, and rejected by family). Commercial kidney transplantation is reported to result in ramifications for the donors' mental, physical, and social well-being. Not only do they remain in poverty, they lose dignity, sense of purpose, respect, relationships, and livelihood. Review of this published literature supports the need for effective implementation of the WHO guiding principles and legislated regulation to deter potential recipients and healthcare providers from pursuing commercial transplantation. © 2012 The Authors.

Negotiating the integration of new literacies in math and science content: The lived experience of classroom teachers

NASA Astrophysics Data System (ADS)

Wimmer, Jennifer Joy

The purpose of this phenomenological study was to investigate the lived experience of integrating new literacies in math and science content by upper elementary and middle school teachers. This study highlights the lived experience of six teachers including two elementary math teachers, two middle school math teachers, and two middle school science teachers. Data sources included five in-depth interviews, teachers' weekly reflection journals, weekly classroom observations, and one principal interview at each of the three high-needs schools. Data were analyzed through an analytic and thematic approach. A reconstructed story was created for each teacher which provides insight into the teacher as an individual. Additionally, a thematic analysis resulted in the identification of five essential themes across all six stories which included: technology exclusively, rethinking who they are as teachers, stabilizing rather than challenging content, rethinking student learning, circumstances, and futures, and serving official context and discourse. The findings indicate that the teachers' lived experience of integrating new literacies in math and science content was filled with uncertainty and a search for stability. A key implication of this study is the need for quality professional development that provides teachers with the opportunity to learn about, question, and rethink the intersection of new literacies, content area literacy, and teacher knowledge.

Background Medical schools include career direction experiences to help students make informed career decisions. Most experiences are short, precluding students from attaining adequate exposure to long-term encounters within medicine. We investigated the impact of the First Patient Program (FPP), which fosters longitudinal patient exposure by pairing junior medical students with chronically ill patients through their healthcare journey, in instilling career direction. Methods Medical students who completed at least 6-months in the FPP participated in a cross-sectional survey. Students’ answers were analyzed with respect to the number of FPP appointments attended. Thematic analysis was conducted to explore qualitative responses. Results One hundred and forty-eight students participated in the survey. Only 28 (19%) students stated that the FPP informed their career decisions. Thirty-nine percent of students who attended four or more appointments indicated that the FPP informed their career decisions, compared to 16% of students who attended less (p=0.021). Thematic analysis revealed two themes: 1) Students focused mainly on patient encounters within FPP; and 2) Students sought career directions from other experiences. Conclusion The majority of students did not attain career guidance from the FPP, but rather used the program to understand the impact of chronic illness from the patient’s perspective. PMID:28344721

Background: Despite known health benefits of spiritual care and high patient interest in discussing spirituality with their physicians, the frequency of spiritual discussions in the medical consultation is low. We investigated spiritual conversations for doctors caring for patients with advanced cancer; why these conversations so difficult; and what the underlying challenges are for discussing spirituality with patients; Methods: Participants were contacted through the Australian and New Zealand Society of Palliative Medicine and the Medical Oncology Group of Australia, including physicians from two secular countries. Semi-structured interviews were taped and transcribed verbatim. The text was analyzed using thematic analysis; Results: Thematic saturation was reached after 23 participants had been interviewed. The following themes were identified: (1) confusing spirituality with religion; (2) peer pressure; (3) personal spirituality; (4) institutional factors; (5) historical factors; Conclusion: This study explored the underlying attitudes contributing to the reluctance doctors have to discuss spirituality in the medical consultation. Underlying confusion regarding the differences between religion and spirituality, and the current suspicion with which religion is regarded in medicine needs to be addressed if discussion of spirituality in the medical consultation is to become routine. Historical opposition to a biopsychosocial-spiritual model of the human being is problematic. PMID:27598212

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

Lin, Chien-Jer Charles

2015-01-01

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.

A Thematic Analysis of Self-described Authentic Leadership Behaviors Among Experienced Nurse Executives.

PubMed

Alexander, Catherine; Lopez, Ruth Palan

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.

An initial analysis of LANDSAT 4 thematic mapper (TM) data for the delineation and classification of agricultural, forested wetland, and urban land covers was conducted. A study area in Poinsett County, Arkansas was used to evaluate a classification of agricultural lands derived from multitemporal LANDSAT multispectral scanner (MSS) data in comparison with a classification of TM data for the same area. Data over Reelfoot Lake in northwestern Tennessee were utilized to evaluate the TM for delineating forested wetland species. A classification of the study area was assessed for accuracy in discriminating five forested wetland categories. Finally, the TM data were used to identify urban features within a small city. A computer generated classification of Union City, Tennessee was analyzed for accuracy in delineating urban land covers. An evaluation of digitally enhanced TM data using principal components analysis to facilitate photointerpretation of urban features was also performed.

Little evidence exists on health care provider (HCP) prescriptions for children’s outdoor physical activity (PA). Semistructured interviews were conducted with 15 children’s HCPs to explore perspectives on outdoor PA prescription programs for children and barriers to implementation. Thematic analytic techniques were used to analyze the data. Most participants reported an awareness of health benefits to children being in the outdoors. Ten themes emerged from the data related to 3 thematic categories: (1) current strategies that HCPs are using to promote PA among children, (2) barriers that HCPs see to prescribing outdoor PA, and (3) potential strategies for promoting outdoor PA among children. Assessment of the local outdoor PA environment and resource development must be done prior to a prescription program. HCPs should be skilled in conducting conversations and setting goals related to outdoor PA tailored to the patient. Developing a system for follow-up with patients on established goals should also be included. PMID:29152542

Kogut, J.; Larduinat, E.

1984-01-01

The potential effects of high frequency vibrations on the final Thematic Mapper (TM) image are evaluated for 26 scenes. The angular displacements of the TM detectors from their nominal pointing directions as measured by the TM Angular Displacement Sensor (ADS) and the spacecraft Dry Rotor Inertial Reference Unit (DRIRU) give data on the along scan and cross scan high frequency vibrations present in each scan of a scene. These measurements are to find the maximum overlap and underlap between successive scans, and to analyze the spectrum of the high frequency vibrations acting on the detectors. The Fourier spectrum of the along scan and cross scan vibrations for each scene also evaluated. The spectra of the scenes examined indicate that the high frequency vibrations arise primarily from the motion of the TM and MSS mirrors, and that their amplitudes are well within expected ranges.

Skylab/EREP S190A and S190B film products were optically enhanced and visually interpreted to extract data suitable for; (1) mapping coastal land use; (2) inventorying wetlands vegetation; (3) monitoring tidal conditions; (4) observing suspended sediment patterns; (5) charting surface currents; (6) locating coastal fronts and water mass boundaries; (7) monitoring industrial and municipal waste dumps in the ocean; (8) determining the size and flow direction of river, bay and man-made discharge plumes; and (9) observing ship traffic. Film products were visually analyzed to identify and map ten land-use and vegetation categories at a scale of 1:125,000. Digital tapes from the multispectral scanner were used to prepare thematic maps of land use. Classification accuracies obtained by comparison of derived thematic maps of land-use with USGS-CARETS land-use maps in southern Delaware ranged from 44 percent to 100 percent.

Working with difference: Thematic concepts of Japanese nurses working in New Zealand.

2016-03-01

The purpose of this study was to compare the differences experienced by Japanese nurses working in New Zealand from an organizational and personal perspective, using a qualitative approach. Interview data was analyzed using a thematic method to abstract increasing levels of themes until one main theme explained the data: finding a voice. This core theme demonstrated that Japanese nurses had to learn to accommodate difference while learning to speak up. Moreover, this needed to occur through a number of cultural filters. The principal conclusion was that migrant nurses face multiple personal and organizational challenges when working in a new environment. Finding a voice is the method in which nurses learn to communicate and work within new healthcare settings. Nurses use a number of filters to manage the transition. The host country needs to recognize these differences and accommodate them through orientation modules. © 2015 Wiley Publishing Asia Pty Ltd.

This exploratory study investigated nursing students' perceptions and attitudes about spirituality and spiritual care in practice. A qualitative interpretative approach was used to investigate the research question. In-depth interviews were conducted with 16 final-year preregistration nursing students from 3 different educational institutions offering a degree or diploma program in Singapore. Data were analyzed using the Miles and Huberman's method of thematic analysis. Thematic analysis identified three themes: (a) students' perceptions of spirituality, (b) spiritual care, and (c) factors influencing spiritual care in practice. The study informed that though young, spirituality matters to the nursing students. Accordingly, nursing is perceived to play an integral role in spiritual care. Enabling factors need to be systematically addressed both in the education and practice arenas before the perennial issue of disconnect between development and implementation of spirituality in practice can be bridged.

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

NASA Astrophysics Data System (ADS)

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.

Knowledge transfer in pediatric rehabilitation is challenging and requires active, multifaceted strategies. The use of knowledge brokers (KBs) is one such strategy noted to promote clinician behavior change. The success of using KBs to transfer knowledge relies on their ability to adapt to ever-changing clinical contexts. In addition, with the rapid growth of online platforms as knowledge transfer forums, KBs must become effective in virtual environments. Although the role of KBs has been studied in various clinical contexts, their emerging role in specific online environments designed to support evidence-based behavior change has not yet been described. Our objective is to describe the roles of, and strategies used by, four KBs involved in a virtual community of practice to guide and inform future online KB interventions. A descriptive design guided this study and a thematic content analysis process was used to analyze online KB postings. The Promoting Action on Research in Health Sciences knowledge transfer framework and online andragogical learning theories assisted in the coding. A thematic map was created illustrating the links between KBs' strategies and emerging roles in the virtual environment. We analyzed 95 posts and identified three roles: 1) context architect: promoting a respectful learning environment, 2) knowledge sharing promoter: building capacity, and 3) linkage creator: connecting research-to-practice. Strategies used by KBs reflected invitational, constructivism, and connectivism approaches, with roles and strategies changing over time. This study increases our understanding of the actions of KBs in virtual contexts to foster uptake of research evidence in pediatric physiotherapy. Our results provide valuable information about the knowledge and skills required by individuals to fulfill this role in virtual environments.

Lakes are dominant landforms in the National Petroleum Reserve Alaska (NPRA) as well as important social and ecological resources. Of recent importance is the management of these freshwater ecosystems because lakes deeper than maximum ice thickness provide an important and often sole source of liquid water for aquatic biota, villages, and industry during winter. To better understand seasonal and annual hydrodynamics in the context of lake morphometry, we analyzed lakes in two adjacent areas where winter water use is expected to increase in the near future because of industrial expansion. Landsat Thematic Mapper and Enhanced Thematic Mapper Plus imagery acquired between 1985 and 2007 were analyzed and compared with climate data to understand interannual variability. Measured changes in lake area extent varied by 0.6% and were significantly correlated to total precipitation in the preceding 12 months (p < 0.05). Using this relation, the modeled lake area extent from 1985 to 2007 showed no long-term trends. In addition, high-resolution aerial photography, bathymetric surveys, water-level monitoring, and lake-ice thickness measurements and growth models were used to better understand seasonal hydrodynamics, surface area-to-volume relations, winter water availability, and more permanent changes related to geomorphic change. Together, these results describe how lakes vary seasonally and annually in two critical areas of the NPRA and provide simple models to help better predict variation in lake-water supply. Our findings suggest that both overestimation and underestimation of actual available winter water volume may occur regularly, and this understanding may help better inform management strategies as future resource use expands in the NPRA.

Collected surface-sediment samples in coastal water around Mekong Delta (from distributary channels to Ca Mau Peninsula) were analyzed to determine surface-sediment grain-size distribution and sediment-transport trend in the subaqueous Mekong Delta. The grain-size data set of 238 samples was obtained by using the laser instrument Mastersizer 2000 and LS Particle Size Analyzer. Fourteen samples were selected for geochemical analysis (total-organic and carbonate content). These geochemical results were used to assist in interpreting variations of granulometricparamenters along the cross-shore transects. Nine transects were examined from CungHau river mouth to Ca Mau Peninsula and six thematic maps on the whole study area were made. The research results indicate that: (1) generally, the sediment becomes finer from the delta front downwards to prodelta and becomes coarser again and poorer sorted on the adjacent inner shelf due to different sources of sediment; (2) sediment-granulometry parameters vary among sedimentary sub-environments of the underwater part of Mekong Delta, the distance from sediment source and hydrodynamic regime controlling each region; (3) the net sediment transport is southwest toward the Ca Mau Peninsula.

In last decades, there have been a decline in natural resources, becoming important to develop reliable methodologies for their management. The appearance of very high resolution sensors has offered a practical and cost-effective means for a good environmental management. In this context, improvements are needed for obtaining higher quality of the information available in order to get reliable classified images. Thus, pansharpening enhances the spatial resolution of the multispectral band by incorporating information from the panchromatic image. The main goal in the study is to implement pixel and object-based classification techniques applied to the fused imagery using different pansharpening algorithms and the evaluation of thematic maps generated that serve to obtain accurate information for the conservation of natural resources. A vulnerable heterogenic ecosystem from Canary Islands (Spain) was chosen, Teide National Park, and Worldview-2 high resolution imagery was employed. The classes considered of interest were set by the National Park conservation managers. 7 pansharpening techniques (GS, FIHS, HCS, MTF based, Wavelet `à trous' and Weighted Wavelet `à trous' through Fractal Dimension Maps) were chosen in order to improve the data quality with the goal to analyze the vegetation classes. Next, different classification algorithms were applied at pixel-based and object-based approach, moreover, an accuracy assessment of the different thematic maps obtained were performed. The highest classification accuracy was obtained applying Support Vector Machine classifier at object-based approach in the Weighted Wavelet `à trous' through Fractal Dimension Maps fused image. Finally, highlight the difficulty of the classification in Teide ecosystem due to the heterogeneity and the small size of the species. Thus, it is important to obtain accurate thematic maps for further studies in the management and conservation of natural resources.

A simulation study was carried out to characterize atmospheric effects in LANDSAT-D Thematic Mapper data. In particular, the objective was to determine if any differences would result from using a linear vs. a conical scanning geometry. Insight also was gained about the overall effect of the atmosphere on Thematic Mapper signals, together with the effects of time of day. An added analysis was made of the geometric potential for direct specular reflections (sun glint). The ERIM multispectral system simulation model was used to compute inband Thematic Mapper radiances, taking into account sensor, atmospheric, and surface characteristics. Separate analyses were carried out for the thermal band and seven bands defined in the reflective spectral region. Reflective-region radiances were computed for 40 deg N, 0 deg, and 40 deg S latitudes; June, Mar., and Dec. days; and 9:30 and 11:00 AM solar times for both linear and conical scan modes. Also, accurate simulations of solar and viewing geometries throughout Thematic Mapper orbits were made. It is shown that the atmosphere plays an important role in determining Thematic Mapper radiances, with atmospheric path radiance being the major component of total radiances for short wavelengths and decreasing in importance as wavelength increases. Path radiance is shown to depend heavily on the direct radiation scattering angle and on haze content. Scan-angle-dependent variations were shown to be substantial, especially for the short-wavelength bands.

Spatial disposition of chemical elements including heavy metals in the soil environment is a very important information during preparation of the thematic maps for the environmental protection and/or spatial planning. This knowledge is also essential for the earth's surface and soil's monitoring, designation of areas requiring improvement including remediation. The main source of anthropogenic pollution of soil with heavy metals are industry related to the mining coal and liquid fuels, mining and metallurgy, chemical industry, energy production, waste management, agriculture and transport. The geochemical maps as a kind of specific thematic maps made on the basis of datasets obtained from the Polish Geological Institute's resources allow to get to know the spatial distribution of different chemical elements including heavy metals in soil. The results of the research carried out by the Polish Geological Institute showed strong contamination in some regions in Poland mainly with arsenic, cadmium, lead and nickel. For this reason it was the point to prepare geochemical maps showing contamination of soil with heavy metals, and determine main sources of contamination and zones where heavy metals concentration was higher than acceptable contents. It was also presented a summary map of soil contamination with heavy metals. Additionally, location of highly contaminated zones was compiled with predominant in those areas types of arable soils and then results were thoroughly analyzed. This information can provide a base for further detailed studies on the soil contamination with heavy metals.

Two experiments investigated whether dealing with a homogeneous subset of syllogisms with time-constrained responses encouraged participants to develop and use heuristics for abstract (Experiment 1) and thematic (Experiment 2) syllogisms. An atmosphere-based heuristic accounted for most responses with both abstract and thematic syllogisms. With thematic syllogisms, a weaker effect of a belief heuristic was also observed, mainly where the correct response was inconsistent with the atmosphere of the premises. Analytic processes appear to have played little role in the time-constrained condition, whereas their involvement increased in a self-paced, unconstrained condition. From a dual-process perspective, the results further specify how task demands affect the recruitment of heuristic and analytic systems of reasoning. Because the syllogisms and experimental procedure were the same as those used in a previous neuroimaging study by Goel, Buchel, Frith, and Dolan (2000), the result also deepen our understanding of the cognitive processes investigated by that study.

Analysis of thematic mapper simulator data collected over eastern North Dakota

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.

Byrne, M M

2001-01-01

This article describes research that sought to identify and critique selected content areas from three nursing fundamentals textbooks for the presence or absence of racial bias embedded in the portrayal of African Americans. The analyzed content areas were the history of nursing, cultural content, and physical assessment/hygiene parameters. A researcher-developed guide was used for data collection and analysis of textual language, illustrations, linguistics, and references. A thematic analysis resulted in I I themes reflecting the portrayal of African Americans in these sampled textbooks. An interpretive analysis with a lens of Sadker and Sadker's categories of bias, along with other literary and theoretical contexts, were used to explore for the presence or absence of racial bias. Recommendations for nursing education are provided.

The newly built Caste spectropolarimeters gave satisfactory performance during tests in the solar radiometer and helicopter modes. A bandwidth normalization technique based on analysis of the moments of the spectral responsivity curves was used to analyze the spectral bands of the MSS and TM subsystems of LANDSAT 4 and 5 satellites. Results include the effective wavelength, the bandpass, the wavelength limits, and the normalized responsivity for each spectral channel. Temperature coefficients for TM PF channel 6 were also derived. The moments normalization method used yields sensor parameters whose derivation is independent of source characteristics (i.e., incident solar spectral irradiance, atmospheric transmittance, or ground reflectance). The errors expected using these parameters are lower than those expected using other normalization methods.

This study aimed to identify and analyze the relations between aging and work. This was a case study in the maintenance engineering division of a high-complexity hospital in the city of São Paulo, Brazil. In September and October 2015, 16 semi-structured interviews were held with the division heads and other workers with a minimum age of 50 years. The data were analyzed with thematic content analysis. Although the workers experienced difficulties resulting from the aging process, these did not prevent them from performing their work activities, since they developed strategies through their knowhow to compensate for their functional losses and/or declines. Still, they felt limited and demotivated due to the poor working conditions, outsourcing of the division, and the prevailing workload organization. Thus, in this division, the working conditions and organization had more impact than the aging process on the individuals' daily work routine.

In assessing the accuracy of classification techniques for Thematic Mapper data the consistency of the detector-to-detector response is critical. Preliminary studies were undertaken, therefore, to assess the significance of this factor for the TM. The overall structure of the band relationships can be examined by principal component analysis. In order to examine the utility of the Thematic Mapper data more carefully, six different land cover classes approximately Anderson level 1 were selected. These included an area of water from the sediment-laden Mississippi, woodland, agricultural land and urban land. A plume class was also selected which includes the plume of smoke emanating from the power station and drifting over the Mississippi river.

A self-contained, portable, hand-radiometer designed for field usage was constructed and tested. The device, consisting of a hand-held probe containing three sensors and a strap supported electronic module, weighs 4 1/2 kilograms. It is powered by flashlight and transistor radio batteries, utilizes two silicon and one lead sulfide detectors, has three liquid crystal displays, sample and hold radiometric sampling, and its spectral configuration corresponds to LANDSAT-D's thematic mapper bands. The device was designed to support thematic mapper ground-truth data collection efforts and to facilitate 'in situ' ground-based remote sensing studies of natural materials. Prototype instruments were extensively tested under laboratory and field conditions with excellent results.

Analyzing existing conventional soil information sources to be incorporated in thematic Spatial Data Infrastructures

NASA Astrophysics Data System (ADS)

Pascual-Aguilar, J. A.; Rubio, J. L.; Domínguez, J.; Andreu, V.

2012-04-01

New information technologies give the possibility of widespread dissemination of spatial information to different geographical scales from continental to local by means of Spatial Data Infrastructures. Also administrative awareness on the need for open access information services has allowed the citizens access to this spatial information through development of legal documents, such as the INSPIRE Directive of the European Union, adapted by national laws as in the case of Spain. The translation of the general criteria of generic Spatial Data Infrastructures (SDI) to thematic ones is a crucial point for the progress of these instruments as large tool for the dissemination of information. In such case, it must be added to the intrinsic criteria of digital information, such as the harmonization information and the disclosure of metadata, the own environmental information characteristics and the techniques employed in obtaining it. In the case of inventories and mapping of soils, existing information obtained by traditional means, prior to the digital technologies, is considered to be a source of valid information, as well as unique, for the development of thematic SDI. In this work, an evaluation of existing and accessible information that constitutes the basis for building a thematic SDI of soils in Spain is undertaken. This information framework has common features to other European Union states. From a set of more than 1,500 publications corresponding to the national territory of Spain, the study was carried out in those documents (94) found for five autonomous regions of northern Iberian Peninsula (Asturias, Cantabria, Basque Country, Navarra and La Rioja). The analysis was performed taking into account the criteria of soil mapping and inventories. The results obtained show a wide variation in almost all the criteria: geographic representation (projections, scales) and geo-referencing the location of the profiles, map location of profiles integrated with edaphic units, description and taxonomic classification systems of soils (FAO, Soil taxonomy, etc.), amount and type of soil analysis parameters and dates of the inventories. In conclusion, the construction of thematic SDI on soil should take into account, prior to the integration of all maps and inventories, a series of processes of harmonization that allows spatial continuity between existing information and also temporal identification of the inventories and maps. This should require the development of at least two types of integration tools: (1) enabling spatial continuity without contradictions between maps made at different times and with different criteria and (2) the development of information systems data (metadata) to highlight the characteristics of information and connection possibilities with other sources that comprise the Spatial Data Infrastructure.

Trends of psychology-related research on euthanasia: a qualitative software-based thematic analysis of journal abstracts.

PubMed

Caputo, Andrea

2015-01-01

Euthanasia has received increasing attention in both academic and public debates as one of the most controversial issues. However, the contribution of psychology-related themes to the topic has had little role on these ongoing debates. The aim of the present study is twofold: (1) to explore the main themes relating to euthanasia as provided by psychology-related research; (2) to analyze the temporal trends of psychology-related research on euthanasia over the last decades. A comprehensive search of academic literature was conducted on PsychINFO database. A qualitative software-based thematic analysis was carried out on 602 journal abstracts published from 1935 to 2014. This study highlighted four different thematic areas which characterized the scientific discourse on euthanasia: (1) moral values, in terms of religious, philosophical, and social implications concerning the individual's decision to die; (2) professional ethics, in terms of health and social workers' legal responsibility in death assistance; (3) end-of-life care, with regard to medical options provided to support individuals nearing death; and (4) patient's right to healthcare, in terms of access to palliative care and better quality of dying. Euthanasia discourse over the last decades seems to be overall characterized by two main dimensions: (1) the increasing trend of social legitimacy and acceptability of euthanasia over time, which moved from ethical to healthcare issues; and (2) the curvilinear temporal trend about the request/provision process in euthanasia, which moved from patient's decision for ending life (mainly characterizing the most past and recent research) to the role of health professionals (with a peak in the 1990s). The results suggest palliative care as a potential future research area which can provide healthcare providers with skills to 'connect' with patients, understand patients' hidden agendas, and grant a good quality of life and dying process.

2015-01-01

Objective An integrated perspective on the relevant qualitative findings on the experience of screen time in youth can inform the development of hypotheses to be tested in future research and can guide the development of interventions to decrease sedentary behavior. The purpose of this qualitative metasynthesis was to explore parent, youth, and educational professionals’ perceptions of barriers to, and facilitators of, reducing youth screen time. Method Qualitative metasynthesis techniques were used to analyze and synthesize 15 qualitative studies of screen time among youth (11–18 years) meeting inclusion criteria. The phrases, quotes, and/or author interpretations (i.e., theme or subtheme) were recorded in a data display matrix to facilitate article comparisons. Codes were collapsed into 23 categories of similar conceptual meaning and 3 overarching themes were derived using thematic analysis procedures. Results Study sample sizes ranged from 6 to 270 participants from 6 countries. Data collection methods included focus groups (n = 6), interviews (n = 4), focus group and interviews (n = 4), and naturalistic observation (n = 1) with youth and/or parents. Data analysis techniques included thematic analysis (n = 9), content analysis (n = 3), grounded theory (n = 1), observation (n = 1), and interpretive phenomenological analysis (n = 1). Three thematic categories were identified: (a) youth’s norms—screen time is an integral part of daily life, and facilitates opportunities for entertainment, social interaction, and escapism; (b) family dynamics and parental roles—parents are conflicted and send mixed messages about the appropriate uses and amounts of screen time; and, (c) resources and environment—engagement in screen time is dependent on school, community, neighborhood, and home environmental contexts. Conclusions Screen time is an established norm in many youth cultures, presenting barriers to behavior change. Parents recognize the importance of reducing youth screen time, but model and promote engagement themselves. For youth and parents, mutually agreed rules, limits, and parental monitoring of screen time were perceived as likely to be effective. PMID:25822054

2018-05-01

Transition into undergraduate education programs is stressful and impacts students' well-being and academic achievement. Previous research indicates nursing students experience stress, depression, anxiety, and poor lifestyle habits which interfere with learning. However, nursing students' experience of transition into nursing programs has not been well studied. Incongruence exists between this lack of research and the desire to foster student success. This study analyzed students' experiences of initial transition into a nursing program. An embedded mixed method design. A single site of a direct-entry, four year baccalaureate Canadian nursing program. All first year nursing students enrolled in the fall term of 2016. This study combined the Student Adaptation to College Questionnaire (SACQ) with a subset of participants participating in qualitative focus groups. Quantitative data was analyzed using descriptive statistics to identify statistically significant differences in full-scale and subscale scores. Qualitative data was analyzed utilizing thematic analysis. Significant differences were seen between those who moved to attend university and those who did not, with those who moved scoring lower on the Academic Adjustment subscale. Focus group thematic analysis highlighted how students experienced initial transition into a baccalaureate nursing program. Identified themes included reframing supports, splitting focus/finding focus, negotiating own expectations, negotiating others' expectations, and forming identity. These findings form the Undergraduate Nursing Initial Transition (UNIT) Framework. Significance of this research includes applications in faculty development and program supports to increase student success in the first year of nursing and to provide foundational success for ongoing nursing practice.

Testing the effect of framing and sourcing in health news stories.

PubMed

Coleman, Renita; Thorson, Esther; Wilkins, Lee

2011-10-01

This study examines whether changing the way news stories report on health can induce shifts in readers' perceptions of problems of obesity, diabetes, immigrant health, and smoking. The authors manipulated two variables in a controlled experiment: the quality of sourcing-the number of sources and their expertise-and the framing-changing from an episodic, traditional frame to a thematic frame that incorporated information on context, risk factors, prevention strategies, and social attributions of responsibility. The authors found that a thematic frame made readers more supportive of public policy changes and encouraged them to improve their own health behaviors. However, it did not alter their attributions of responsibility for health problems from one of blaming individuals to seeing the larger social factors. Adding richer sourcing to the thematic frame did not increase these effects, nor did readers find the thematic stories to be more interesting, relevant, believable, important, and informative. In addition, there were differential results because of story topics that represent uncontrolled effects. The implications for improving health reporting to encourage positive change in society are discussed.

Differential processing of thematic and categorical conceptual relations in spoken word production.

PubMed

de Zubicaray, Greig I; Hansen, Samuel; McMahon, Katie L

2013-02-01

Studies of semantic context effects in spoken word production have typically distinguished between categorical (or taxonomic) and associative relations. However, associates tend to confound semantic features or morphological representations, such as whole-part relations and compounds (e.g., BOAT-anchor, BEE-hive). Using a picture-word interference paradigm and functional magnetic resonance imaging (fMRI), we manipulated categorical (COW-rat) and thematic (COW-pasture) TARGET-distractor relations in a balanced design, finding interference and facilitation effects on naming latencies, respectively, as well as differential patterns of brain activation compared with an unrelated distractor condition. While both types of distractor relation activated the middle portion of the left middle temporal gyrus (MTG) consistent with retrieval of conceptual or lexical representations, categorical relations involved additional activation of posterior left MTG, consistent with retrieval of a lexical cohort. Thematic relations involved additional activation of the left angular gyrus. These results converge with recent lesion evidence implicating the left inferior parietal lobe in processing thematic relations and may indicate a potential role for this region during spoken word production. 2013 APA, all rights reserved

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

PubMed

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.

Thematic knowledge, artifact concepts, and the left posterior temporal lobe: Where action and object semantics converge

PubMed Central

Kalénine, Solène; Buxbaum, Laurel J.

2016-01-01

Converging evidence supports the existence of functionally and neuroanatomically distinct taxonomic (similarity-based; e.g., hammer-screwdriver) and thematic (event-based; e.g., hammer-nail) semantic systems. Processing of thematic relations between objects has been shown to selectively recruit the left posterior temporoparietal cortex. Similar posterior regions have been also been shown to be critical for knowledge of relationships between actions and manipulable human-made objects (artifacts). Based on the hypothesis that thematic relationships for artifacts are based, at least in part, on action relationships, we assessed the prediction that the same regions of the left posterior temporoparietal cortex would be critical for conceptual processing of artifact-related actions and thematic relations for artifacts. To test this hypothesis, we evaluated processing of taxonomic and thematic relations for artifact and natural objects as well as artifact action knowledge (gesture recognition) abilities in a large sample of 48 stroke patients with a range of lesion foci in the left hemisphere. Like control participants, patients identified thematic relations faster than taxonomic relations for artifacts, whereas they identified taxonomic relations faster than thematic relations for natural objects. Moreover, response times for identifying thematic relations for artifacts selectively predicted performance in gesture recognition. Whole brain Voxel Based Lesion-Symptom Mapping (VLSM) analyses and Region of Interest (ROI) regression analyses further demonstrated that lesions to the left posterior temporal cortex, overlapping with LTO and visual motion area hMT+, were associated both with relatively slower response times in identifying thematic relations for artifacts and poorer artifact action knowledge in patients. These findings provide novel insights into the functional role of left posterior temporal cortex in thematic knowledge, and suggest that the close association between thematic relations for artifacts and action representations may reflect their common dependence on visual motion and manipulation information.

Pluta, A; Ulatowska, H; Gawron, N; Sobanska, M; Lojek, E

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.

Thematic mapper research in the earth sciences: Small scale patches of suspended matter and phytoplankton in the Elbe River Estuary, German Bight and Tidal Flats

1987-01-01

A Thematic Mapper (TM) field experiment was followed by a data analysis to determine TM capabilities for analysis of suspended matter and phytoplankton. Factor analysis showed that suspended matter concentration, atmospheric scattering, and sea surface temperature can be retrieved as independent factors which determine the variation in the TM data over water areas. Spectral channels in the near infrared open the possibility of determining the Angstrom exponent better than for the coastal zone color scanner. The suspended matter distribution may then be calculated by the absolute radiance of channel 2 or 3 or the ratio of both. There is no indication of whether separation of chlorophyll is possible. The distribution of suspended matter and sea surface temperature can be observed with the expected fine structure. A good correlation between water depth and suspended matter distribution as found from ship data can now be analyzed for an entire area by the synoptic view of the TM scenes.

Progress during ERIM's tenth quarter of effort under the LANDSAT-4 and 5 Image Data Quality Assessment program for the Thematic Mapper is described. Coincident LANDSAT-4 and 5 fully corrected (CCT-PT) TM data are analyzed in more detail and revised band-by-band relationships between the two sensors derived. An analysis technique employing the matching of cumulative distributions is developed and used and is believed to offer advantages over the histogram matching procedure currently used to produce LANDSAT data. Multiplicative factors ranging from 0.987 to 1.145 and offsets ranging from -2.7 to -6.2 video quantum levels are required to cause LANDSAT-5 data to match LANDSAT-4 data values. Evidence of low level clipping is found in TM Bands 5 and 7 of LANDSAT-5 but not LANDSAT-4. Analysis of the information content of LANDSAT TM and MSS data is continued. Components of information loss are identified and quantified and the effects of coarsened quantization are explored.

An evaluation of simulated Thematic Mapper data and Landsat MSS data for discriminating suburban and regional land use and land cover

NASA Technical Reports Server (NTRS)

Toll, D. L.

1984-01-01

An airborne multispectral scanner, operating in the same spectral channels as the Landsat Thematic Mapper (TM), was used in a region east of Denver, CO, for a simulation test performed in the framework of using TM to discriminate the level I and level II classes. It is noted that at the 30-m spatial resolution of the Thematic Mapper Simulator (TMS) the overall discrimination for such classes as commercial/industrial land, rangeland, irrigated sod, irrigated alfalfa, and irrigated pasture was superior to that of the Landsat Multispectral Scanner, primarily due to four added spectral bands. For residential and other spectrally heterogeneous classes, however, the higher resolution of TMS resulted in increased variability within the class and a larger spectral overlap.

Study on identifying deciduous forest by the method of feature space transformation

2009-10-01

The thematic remotely sensed information extraction is always one of puzzling nuts which the remote sensing science faces, so many remote sensing scientists devotes diligently to this domain research. The methods of thematic information extraction include two kinds of the visual interpretation and the computer interpretation, the developing direction of which is intellectualization and comprehensive modularization. The paper tries to develop the intelligent extraction method of feature space transformation for the deciduous forest thematic information extraction in Changping district of Beijing city. The whole Chinese-Brazil resources satellite images received in 2005 are used to extract the deciduous forest coverage area by feature space transformation method and linear spectral decomposing method, and the result from remote sensing is similar to woodland resource census data by Chinese forestry bureau in 2004.

Landsat thematic mapper (TM) soil variability analysis over Webster County, Iowa

Thompson, D. R.; Henderson, K. E.; Pitts, D. E.

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.

Cancer Survivorship in the Age of YouTube and Social Media: A Narrative Analysis

PubMed Central

Hunt, Yvonne; Folkers, Anna

2011-01-01

Background As evidenced by the increasing popularity of YouTube (www.youtube.com), personal narratives shared through social media are an area of rapid development in communication among cancer survivors. Identifying the thematic and linguistic characteristics of YouTube cancer stories can provide a better understanding of this naturally occurring communication channel and inform social media communication efforts aiming to use personal stories to reach individuals with serious illnesses. Objective The objective of our study was to provide an in-depth description of authentic personal cancer stories. Through a linguistically based narrative analysis of YouTube stories, the analysis explicates the common attributes of these narratives. Methods Informed by narrative theories, we conducted an iterative, bottom-up analysis of 35 YouTube videos identified by the search terms “cancer survivor” and “cancer stories”. A list of shared thematic and linguistic characteristics was identified and analyzed. Results A subnarrative on the cancer diagnosis was present in 86% (30/35) of the stories under analysis. These diagnostic narratives were characterized by dramatic tension, emotional engagement, markers of the loss of agency or control, depersonalized reference to the medical personnel, and the unexpectedness of a cancer diagnosis. The analysis highlights the themes of story authenticity and emotional engagement in this online communication medium. Conclusions Internet advances have enabled new and efficient exchange of personal stories, including the sharing of personal cancer experience among cancer survivors and their caregivers. The analytic results of this descriptive study point to the common characteristics of authentic cancer survivorship stories online. Furthermore, the results of this descriptive study may inform development of narrative-based communication, particularly in maintaining authenticity and emotional engagement. PMID:21247864

This study reports on an investigation of water quality calibration algorithms under turbid inland water conditions using Landsat Thematic Mapper (TM) multispectral digital data. TM data and water quality observations (total suspended solids and Secchi disk depth) were obtained near-simultaneously and related using linear regression techniques. The relationships between reflectance and water quality for Green Bay and Lake Michigan were compared with results for Yellowstone and Jackson Lakes, Wyoming. Results show similarities in the water quality-reflectance relationships, however, the algorithms derived for Green Bay - Lake Michigan cannot be extrapolated to Yellowstone and Jackson Lake conditions.

This study examined knowledge, access, utilization, and barriers to use of resources among Black women exposed to multiple types of intimate partner violence in Baltimore, Maryland and the U.S. Virgin Islands (USVI). We analyzed quantitative survey data collected by 163 women recruited from primary care, prenatal or family planning clinics in Baltimore and the USVI. In addition we analyzed qualitative data from in-depth interviews with 11 women. Quantitative data were analyzed using descriptive statistics and qualitative data were analyzed using thematic analysis. A substantial proportion of Black women with multiple types of violence experiences lacked knowledge of, did not have access to, and did not use resources. Barriers to resource use were identified at the individual, relationship, and community levels. There is need for programs to develop awareness, promote access and utilization of resources, and eliminate barriers to resource use among abused Black women.

1983-01-01

The utility of methods for generating TM RLUTS which can improve the quality of the resultant images was investigated. The TM-CCT-ADDS tape was changed to account for a different collection window for the calibration data. Several scenes of Terrebonne Bay, Louisiana and the Grand Bahamas were analyzed to evaluate the radiometric corrections operationally applied to the image data and to investigate several techniques for reducing striping in the images. Printer plots for the TM shutter data were produced and detector statistics were compiled and plotted. These statistics included various combinations of the average shutter counts for each scan before and after DC restore for forward and reverse scans. Results show that striping is caused by the detectors becoming saturated when they view a bright cloud and depress the DC restore level.

Estacio, Emee Vida; Saidy-Khan, Sirandou

2014-01-01

In this article, we explore the experiences of racial microaggression among migrant nurses in the United Kingdom. Eleven migrant nurses kept a reflective diary for 6 weeks to record and reflect on their experiences of living and working in the United Kingdom. The diary entries were then thematically analyzed. The results suggest that migrant nurses experienced racial microaggression from patients and colleagues through racial preferences and bullying. Institutional racism also hindered their opportunities for further training and promotion. As a result, some experienced feelings of anger, frustration, and even paranoia. Despite the negative consequences of racial microaggression on their emotional well-being, incidents were downplayed as trivial because of their vague and subtle nature. To encourage better multicultural interactions in the workplace, supportive organizational infrastructures need to be in place to enhance diversity awareness and to improve mechanisms for reporting and dealing with cases of racial microaggression.

This study investigated videos about Attention Deficit Hyperactivity Disorder (ADHD) on YouTube in terms of issues, sources, and episodic-thematic aspects. A total of 685 videos uploaded onto YouTube between 2006 and 2014 were content analyzed. Results demonstrated that the top three key issues about ADHD were symptom, child, and treatment. Doctor, patient, and supporter were the three most interviewed sources. Videos from the public sector including the government, company representative, and public organizations were relatively rare compared to other sources suggesting the potential for a greater role for the government and public sector contributions to YouTube to provide credible information relevant to public awareness, campaigns, and policy announcements. Meanwhile, many personal videos in the episodic frame advocated social solutions. This result implies that YouTube videos about health information from the private sectors have the potential to affect change at the social level.

ABSTRACT Objective: to investigate health professionals' knowledge about the concept, assessment and intervention in fatigue in children and adolescents with cancer. Method: exploratory study with qualitative approach, with 53 health professionals (10 nurses, 33 assistant nurses, 3 physicians, 3 nutritionists, 2 psychologists and 2 physical therapists). Semi structured interviews were held, which were recorded and analyzed by means of inductive thematic content analysis. Results: the data were organized around three themes: knowledge of health professionals about fatigue; identification of fatigue and interventions to relieve fatigue. Conclusion: the results indicate the health professionals' limited knowledge about fatigue, as well as the lack of investment in their training and continuing education. Most of all, the lack of research on the theme in the Brazilian context remains a barrier to support improvements in care for this symptom in children and adolescents with cancer. PMID:27579937

2014-01-01

Background: The probability and severity of effects of induced demand are because of the interaction between a range of factors that can affect physicians and patients behavior. It is also affected by the laws of the markets and organizational arrangements for medical services. This article studies major factors that affect the phenomenon of induced demand with the use of experts’ experiences of the Isfahan University of Medical Sciences. Methods: The research is applied a qualitative method. Semi-structured interview was used for data generation. Participants in this study were people who had been informed in this regard and had to be experienced and were known as experts. Purposive sampling was done for data saturation. Seventeen people were interviewed and criteria such as data “reliability of information” and stability were considered. The anonymity of the interviewees was preserved. The data are transcribed, categorized and then used the thematic analysis. Results: In this study, thematic analysis was conducted, and 77 sub-themes and 3 themes were extracted respectively. The three main themes include infrastructural factors, social factors, and organizational structural factors affecting induced demand. Each of these also has some sub-themes. Conclusions: Results of this research present a framework for analyzing the major causes of induced demand. The causes identified here include complexity of medicine, information mismatch between service providers and consumers, clinical uncertainty, false beliefs, advertisements, insufficient supervision, scarcity of clinical guidelines, weakness of education system, and ignorance of medical ethics. These findings help policymakers to investigate the induced demand phenomenon clear-sighted. PMID:25400888

2016-01-01

Objective Classroom teachers play an important role in facilitating asthma management in school but little is known about their perspectives around asthma management. We examined the perspectives of classroom teachers around barriers to school asthma management. Methods We conducted key informant interviews with 21 inner-city classroom teachers from 3rd to 5th grades in 10 Bronx, New York elementary schools. Sampling continued until thematic saturation was reached. Interviews were recorded, transcribed, and independently coded for common themes. We used thematic and content review to analyze interview data. Results Seven themes representing teachers’ perspectives on in-school asthma management emerged: (1) the problematic process of identifying students with asthma; (2) poor familiarity with the city health department’s asthma initiative and poor general knowledge of school policies on asthma management (3) lack of competency in managing an acute asthma attack in the classroom and poor recognition of symptoms of an asthma attack; (4) lack of confidence in dealing with a hypothetical asthma attack in the classroom; (5) lack of quick access to asthma medication in school; (6) limited communication between school staff; and (7) enthusiasm about learning more about asthma management. Conclusions Our results revealed several barriers contributing to suboptimal in-school asthma management: ineffective ways of identifying students with asthma, lack of teacher knowledge of guidelines on asthma management, lack of comfort in managing students’ asthma, inadequate access to asthma medication in school, and limited communication between school staff. These issues should be considered in the design of interventions to improve in-school asthma management. PMID:27031532

Information obtained from satellite-based systems has moved to the forefront as a method in the identification of many land cover types. Identification of different land features through remote sensing is an effective tool for regional and global assessment of geometric characteristics. Classification data acquired from remote sensing images have a wide variety of applications. In particular, analysis of remote sensing images have special applications in the classification of various types of vegetation. Results obtained from classification studies of a particular area or region serve towards a greater understanding of what parameters (ecological, temporal, etc.) affect the region being analyzed. In this paper, we make a distinction between both types of classification approaches although, focus is given to the unsupervised classification method using 1987 Thematic Mapped (TM) images of Kennedy Space Center.

This is an assistance convergent research, which aimed to investigate the effects of child's hospitalization in the companion family life. It was performed in a hospital located in Goiania-GO, Brazil, where parents of hospitalized children participated in a support group. Data collection occurred from 2010 February to July, through the recording and transcription of group sessions; to analyze the facts and phenomena experienced in the group, it was used the thematic analysis. The results provide subsidies for health professionals that allow them to understand how complex is the experience of "having" and "live" with a family child in situation of illness and hospitalization. We conclude that this experience affects family relationships, mental and physical health, and the maintenance of the social networking of the companion.

The optimum index factor package was used to choose TM band for color compositing. Processing techniques were also used on TM data over several sites to: (1) reduce the amount of data that needs to be processed and analyzed by using statistical methods or by combining full-resolution products with spatially compressed products; (2) digitally process small subareas to improve the visual appearance of large-scale products or to merge different-resolution image data; and (3) evaluate and compare the information content of the different three-band combinations that can be made using the TM data. Results indicate that for some applications the added spectral information over MSS is even more important than the TM's increased spatial resolution.

This case study was conducted to identify barriers of integration of health protection and health promotion in rural workplaces with tailored interventions that address the identified barriers. Data on a workplace's ability to integrate wellness programs and health protection programs were collected through a questionnaire along with a seven-question interview. Descriptive statistics were used to analyze the quantitative data. Qualitative measures were assessed using thematic analysis. Based off the results of the assessments, the company received tailored training sessions. The largest hindrance to organizational support was time. However, improved knowledge about the need and importance of integration helped the participants to conceptualize and plan for more collaboration between departments. New ways to increase integration at workplaces, especially rural workplaces are needed. More comprehensive interventions that include management are also needed.

Progress on defining the minimum Landsat-4 data characteristics needed for agricultural information in the U.S. and assessing the value-added capability of current technology to extract that level of information is reported. Emphasis is laid on the thematic mapper (TM) data and the ground processing facilities. TM data from all 7 bands for a rural Arkansas scene were examined in terms of radiometric, spatial, and geometric fidelity characteristics. Another scene sensed over Iowa was analyzed using three two-channel data sets. Although the TM data were an improvement over MSS data, no value differential was perceived. However, the development of further analysis techniques is still necessary to determine the actual worth of the improved sensor capabilities available with the TM, which actually has an MSS within itself.

This ethnographic case study investigated the science practices of teachers at one public elementary magnet school in light of how school culture influenced science curriculum design and instruction. The purpose of the study was to address how school culture impacted the school's overall treatment of science as a viable content area. Key informant teachers were interviewed to explore their personal beliefs and values, teaching, access to materials, and views of the adopted integrated thematic curriculum model and magnet structure. The resulting data, triangulated with informal observation and artifact collection, were analyzed using a theoretical framework that emphasized five interdependent school culture indicators (values, beliefs, practices, materials, and problems). Findings suggest that the school's culture adversely influenced the treatment of science.

This quantitative and exploratory study analyzed violence against Amazon women presented in print media according to type and severity, and whether aggressors fell under the Maria da Penha law. A total of 181 issues of a regional newspaper were consulted. Based on content analysis, 164 items addressing violence against women were selected and 46 were included in the corpus of analysis. Results were gathered in three thematic groups: women killed with cruelty, sexual violence against women regardless of age, and violence against women and the limitations of the Maria da Penha law. Violence against these women varied in terms of form and severity, including up to homicide. Women are submitted to sexual violence from childhood through adulthood. The enforcement of this law shows the community it has a means to cope with this social phenomenon.

According to attention-restoration theory (ART), natural environments can provide restorative experiences. In this pilot study, a mixed-methods approach was used to examine the potential of using exercise in a natural environment to enhance exercise behaviors. The study included an assessment study and an intervention study (overall n = 19). The participants underwent a standardized exercise program including biking and circuit strength training, either indoors or outdoors in nature. Measurements included connectedness to nature, perceived exertion, perceived environmental restorativeness, enjoyment, affect, future exercise intention, and self-reported exercise behavior. The participants also wrote a brief text describing the way in which the environment influenced their feelings while exercising. Quantitative data were analyzed using the Spearman rank correlation and linear mixed-effects modeling. The qualitative information was analyzed thematically. The integrated results indicated that, in accordance with ART, exercising in nature was associated with a greater potential for restoration and affective responses, which in some participants led to enhanced intention to exercise and increased exercise behavior. However, some perceived that the indoor exercise provided a more effective workout. Further studies on larger samples are needed.

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.

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

Kleindl, William J; Powell, Scott L; Hauer, F Richard

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.

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.

Landsat D Thematic Mapper image dimensionality reduction and geometric correction accuracy

NASA Technical Reports Server (NTRS)

Ford, G. E.

1986-01-01

To characterize and quantify the performance of the Landsat thematic mapper (TM), techniques for dimensionality reduction by linear transformation have been studied and evaluated and the accuracy of the correction of geometric errors in TM images analyzed. Theoretical evaluations and comparisons for existing methods for the design of linear transformation for dimensionality reduction are presented. These methods include the discrete Karhunen Loeve (KL) expansion, Multiple Discriminant Analysis (MDA), Thematic Mapper (TM)-Tasseled Cap Linear Transformation and Singular Value Decomposition (SVD). A unified approach to these design problems is presented in which each method involves optimizing an objective function with respect to the linear transformation matrix. From these studies, four modified methods are proposed. They are referred to as the Space Variant Linear Transformation, the KL Transform-MDA hybrid method, and the First and Second Version of the Weighted MDA method. The modifications involve the assignment of weights to classes to achieve improvements in the class conditional probability of error for classes with high weights. Experimental evaluations of the existing and proposed methods have been performed using the six reflective bands of the TM data. It is shown that in terms of probability of classification error and the percentage of the cumulative eigenvalues, the six reflective bands of the TM data require only a three dimensional feature space. It is shown experimentally as well that for the proposed methods, the classes with high weights have improvements in class conditional probability of error estimates as expected.

Jouravlev, Olessia; McRae, Ken

2016-12-01

Knowledge of thematic relations is an area of increased interest in semantic memory research because it is crucial to many cognitive processes. One methodological issue that researchers face is how to identify pairs of thematically related concepts that are well-established in semantic memory for most people. In this article, we review existing methods of assessing thematic relatedness and provide thematic relatedness production norming data for 100 object concepts. In addition, 1,174 related concept pairs obtained from the production norms were classified as reflecting one of the five subtypes of relations: attributive, argument, coordinate, locative, and temporal. The database and methodology will be useful for researchers interested in the effects of thematic knowledge on language processing, analogical reasoning, similarity judgments, and memory. These data will also benefit researchers interested in investigating potential processing differences among the five types of semantic relations.

The thematic mapper is a multispectral scanner which will be launched aboard Landsat-D in the early 1980s. Compared with previous Landsat scanners, this instrument will have an improved spatial resolution (30 m) and new spectral bands. Designated NS001MS, the scanner is designed to duplicate the thematic mapper spectral bands plus two additional bands (1.0 to 1.3 microns and 2.08 to 2.35 microns) in an aircraft scanner for evaluation and investigation prior to design and launch of the final thematic mapper. Applicable specifications used in defining the thematic mapper were retained in the NS001MS design, primarily with respect to spectral bandwidths, noise equivalent reflectance, and noise equivalent difference temperature. The technical design and operational characteristics of the multispectral scanner (with thematic mapper bands) are discussed.

This paper presents worked examples of two methods of data synthesis (textual narrative and thematic), used in relation to one review, with the aim of enabling researchers to consider the strength of different approaches. Methods A systematic review of lay perspectives of infant size and growth was conducted, locating 19 studies (including both qualitative and quantitative). The data extracted from these were synthesised using both a textual narrative and a thematic synthesis. Results The processes of both methods are presented, showing a stepwise progression to the final synthesis. Both methods led us to similar conclusions about lay views toward infant size and growth. Differences between methods lie in the way they dealt with study quality and heterogeneity. Conclusion On the basis of the work reported here, we consider textual narrative and thematic synthesis have strengths and weaknesses in relation to different research questions. Thematic synthesis holds most potential for hypothesis generation, but may obscure heterogeneity and quality appraisal. Textual narrative synthesis is better able to describe the scope of existing research and account for the strength of evidence, but is less good at identifying commonality. PMID:17224044

Effects of the use of thematic organizers in conjunction with concept mapping on learning, misconceptions, and retention in middle school science class

NASA Astrophysics Data System (ADS)

Keown, Sandra L.

This study was devised to determine effects of the use of interactive thematic organizers and concept maps in middle school science classes during a unit study on minerals. The design, a pretest-posttest control group, consisted of matched groups (three experimental groups and one comparison group). It also included a student survey assessing qualitative aspects of the investigation. The 67 6th-grade students and one science teacher who participated in the study were from an independent K-12 school. Students represented a normal, well-distributed range of abilities. Group I (control) proceeded with their usual method of studying a unit---reading aloud the text and answering workbook questions. Group II worked with interactive thematic organizers, designed to activate prior knowledge and help students make inferences about target concepts in three treatments. Group III created three interactive concept maps, which represented both understandings and misconceptions. Concept maps were reviewed and repaired as students completed each treatment. Group IV participated in both thematic organizer and concept map treatments. Statistical analyses were determined through a pretest and a delayed recall posttest essay for all four groups. Two scores were assigned---one quantitative raw score of correct explicit answers and one rubric score based on the quality of interpretive responses. Group II also received scores for thematic organizer responses. Group III received rubric scores for concept maps. Group IV received all possible scores. Paired t-tests reported comparisons of scores across the treatment groups. A linear regression indicated whether or not concept map misconceptions affected posttest scores. Finally, an ANCOVA reported statistical significance across the four treatment groups. Findings of data analysis indicated statistically significant improvement in posttest scores among students in the three experimental groups. Students who participated in both treatments represented the highest scores among the four groups. Results of the ANCOVA indicated there was statistically significant difference in scores among the four treatments. Recommendations were made to further investigate development of interactive thematic organizers with student-chosen hyperlinks to concepts, as well as a recommendation that researchers investigate teacher understandings of interpretive purpose and form in the creation of thematic organizers.

Mapping is essential for the analysis of the land use and land cover, which influence many environmental processes and properties. For the purpose of the creation of land cover maps, it is important to minimize error. These errors will propagate into later analyses based on these land cover maps. The reliability of land cover maps derived from remotely sensed data depends on an accurate classification. In this study, we have analyzed multispectral data using two different classifiers including Maximum Likelihood Classifier (MLC) and Support Vector Machine (SVM). To pursue this aim, Landsat Thematic Mapper data and identical field-based training sample datasets in Johor Malaysia used for each classification method, which results indicate in five land cover classes forest, oil palm, urban area, water, rubber. Classification results indicate that SVM was more accurate than MLC. With demonstrated capability to produce reliable cover results, the SVM methods should be especially useful for land cover classification.

Development of AHPDST Vulnerability Indexing Model for Groundwater Vulnerability Assessment Using Hydrogeophysical Derived Parameters and GIS Application

2017-04-01

Producing a bias-free vulnerability assessment map model is significantly needed for planning a scheme of groundwater quality protection. This study developed a GIS-based AHPDST vulnerability index model for producing groundwater vulnerability model map in the hard rock terrain, Nigeria by exploiting the potentials of analytic hierarchy process (AHP) and Dempster-Shafer theory (DST) data mining models. The acquired borehole and geophysical data in the study area were processed to derive five groundwater vulnerability conditioning factors (GVCFs), namely recharge rate, aquifer transmissivity, hydraulic conductivity, transverse resistance and longitudinal conductance. The produced GVCFs' thematic maps were multi-criterially analyzed by employing the mechanisms of AHP and DST models to determine the normalized weight ( W) parameter for the GVCFs and mass function factors (MFFs) parameter for the GVCFs' thematic maps' class boundaries, respectively. Based on the application of the weighted linear average technique, the determined W and MFFs parameters were synthesized to develop groundwater vulnerability potential index (GVPI)-based AHPDST model algorithm. The developed model was applied to establish four GVPI mass/belief function indices. The estimates based on the applied GVPI belief function indices were processed in GIS environment to create prospective groundwater vulnerability potential index maps. The most representative of the resulting vulnerability maps (the GVPIBel map) was considered for producing the groundwater vulnerability potential zones (GVPZ) map for the area. The produced GVPZ map established 48 and 52% of the areal extent to be covered by the lows/moderate and highs vulnerable zones, respectively. The success and the prediction rates of the produced GVPZ map were determined using the relative operating characteristics technique to give 82.3 and 77.7%, respectively. The analyzed results reveal that the developed GVPI-based AHPDST model algorithm is capable of producing efficient groundwater vulnerability potential zones prediction map and characterizing the predicted zones uncertainty via the DST mechanism processes in the area. The produced GVPZ map in this study can be used by decision makers to formulate appropriate groundwater management strategies and the approach may be well opted in other hard rock regions of the world, especially in economically poor nations.

The number of university global health training programs has grown in recent years. However, there is little research on the needs of the global health profession. We therefore set out to characterize the global health employment market by analyzing global health job vacancies. We collected data from advertised, paid positions posted to web-based job boards, email listservs, and global health organization websites from November 2015 to May 2016. Data on requirements for education, language proficiency, technical expertise, physical location, and experience level were analyzed for all vacancies. Descriptive statistics were calculated for the aforementioned job characteristics. Associations between technical specialty area and requirements for non-English language proficiency and overseas experience were calculated using Chi-square statistics. A qualitative thematic analysis was performed on a subset of vacancies. We analyzed the data from 1007 global health job vacancies from 127 employers. Among private and non-profit sector vacancies, 40% (n = 354) were for technical or subject matter experts, 20% (n = 177) for program directors, and 16% (n = 139) for managers, compared to 9.8% (n = 87) for entry-level and 13.6% (n = 120) for mid-level positions. The most common technical focus area was program or project management, followed by HIV/AIDS and quantitative analysis. Thematic analysis demonstrated a common emphasis on program operations, relations, design and planning, communication, and management. Our analysis shows a demand for candidates with several years of experience with global health programs, particularly program managers/directors and technical experts, with very few entry-level positions accessible to recent graduates of global health training programs. It is unlikely that global health training programs equip graduates to be competitive for the majority of positions that are currently available in this field.

Indus Deltaic Region (IDR) in Pakistan is an erosion vulnerable coast due to the high deep water wave energy. Livelihood of millions of people depends on the fisheries and mangrove forests in IDR. IDR consists of many creeks where Daboo is a major creek located at southeast of the largest city of Pakistan, Karachi. Unfortunately, there has been no detailed study to analyze the damages of sea water intrusion at a large temporal and spatial scale. Therefore, this study is designed to estimate the effects of sea water inundation based on changing sea water surface salinity and sea surface temperature (SST). Sea surface salinity and SST data from two different surveys in Daboo creek during 1986 and 2010 are analyzed to estimate the damages and extent of sea water intrusion. Mean salinity has increased 33.33% whereas mean SST decreased 13.79% from 1987 to 2010. Spatio-temporal analysis of creek area using LANDSAT 5 Thematic mapper (TM) data for the years 1987 and 2010 shows significant amount of erosion at macro scale. Creek area has increased approximately 9.93% (260.86 m2 per year) which is roughly equal to 60 extensive sized shrimp farms. Further Land Use Land Cover (LULC) analyses for years 2001 and 2014 using LANDSAT 7 Enhanced Thematic Mapper Plus (ETM+) has indicated 42.3% decrease in cultivated land. Wet mud flats have spread out at the inner mouth of creek with enormous increase of 123.3%. Significant sea water intrusion has increased the area of barren land by 37.9%. This also resulted in overall decrease of 6.7% in area covered by mangroves. Therefore, this study recorded a significant evidence of sea water intrusion in IDR that has caused serious damages to community living in the area, economical losses. Additionally, it has also changed the environment by reducing creek biological productivity as reported by earlier studies over other regions of the world.

The generation of runoff and the resultant flash flooding can be substantially larger following wildfire than for similar rainstorms that precede wildfire disturbance. Flash flooding after the 2011 Las Conchas Fire in New Mexico provided the motivation for this investigation to assess postwildfire effects on soil-hydraulic properties (SHPs) and soil-physical properties (SPPs) as a function of remotely sensed burn severity 4 years following the wildfire. A secondary purpose of this report is to illustrate a methodology to determine SHPs that analyzes infiltrometer data by using three different analysis methods. The SPPs and SHPs are measured as a function of remotely sensed burn severity by using the difference in the Normalized Burn Ratio (dNBR) metric for seven sites. The dNBR metric was used to guide field sample collection across a full spectrum of burn severities that covered the range of Monitoring Trends in Burn Severity (MTBS) and Burned Area Reflectance Classification (BARC) thematic classes from low to high severity. The SPPs (initial and saturated soil-water content, bulk density, soil-organic matter, and soil-particle size) and SHPs (field-saturated hydraulic conductivity and sorptivity) were measured under controlled laboratory conditions for soil cores collected in the field. The SHPs were estimated by using tension infiltrometer measurements and three different data analysis methods. These measurements showed large effects of burn severity, focused in the top1 centimeter (cm) of soil, on some SPPs (bulk density, soil organic matter, and particle sizes). The threshold of these bulk density and soil organic matter effects was between 300 and 400 dNBR, which corresponds to a MTBS thematic class between moderate and high burn severity and a BARC4 thematic class of high severity. Gravel content and the content of fines in the top 1 cm of soil had a higher threshold value between 450 and 500 dNBR. Lesser effects on SPPs were observed at depths of 1–3 cm and 3–6 cm. In contrast, SHPs showed little effect from dNBR or from MTBS/BARC4 thematic class. Measurements suggested that 4 years of elapsed time after the wildfire may be sufficient for SHP recovery in this area. These measurements also indicated that SPP differences as a function of burn severity cannot be used as reliable indicators of SHP differences as a function of burn severity.

Background Musculoskeletal injuries occur frequently in elite athletes. Understanding what professionals who work with patients with sports injuries think about prevention has been suggested as an important aspect to improve the effectiveness of programs to prevent sports injuries. Objectives To describe and characterize the opinions of physical therapists, physicians and trainers on 'risk factors' and 'prevention of injury' in elite athletes. Method This is a qualitative study with semi-structured interviews with members of the medical and technical department of the Brazilian delegation who participated in the Pan American Games of Guadalajara 2011. The interview was conducted using two questions: 1) "What do you think can cause injuries in athletes participating in your sport?" 2) "What do you do to prevent injuries in your sport?" The interviews were analyzed in two stages, the identification of thematic units, followed by the categorization and grouping of thematic units. Results We interviewed a total of 30 professionals. Regarding question 1, the main factors attributed as responsible for injury were over-training and incorrect sports techniques. Regarding question 2, the main reported strategies used to prevent injuries were muscle strengthening, nutritional counseling and guidance. Conclusions The main factors affecting the appearance of lesions were over-training, incorrect sports technique, inadequate nutrition and factors related to the athlete's behavior. The main injury prevention strategies were muscle strengthening, nutritional counseling and guidance. PMID:24845023

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

PubMed Central

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

Light from the Waves

For many years limnologists have been looking for an alternative to the Secchi disk. In the mid to late 1970s, Lillesand (then at Minnesota) along with colleagues in Wisconsin began to toy with the idea of using remote sensing satellites to observe lake quality from space. They reasoned that if water quality information could be extracted from images taken by orbiting satellites, the number of lakes monitored could be greatly expanded. For several years, the scientists experimented with data from early Landsat missions, but the data provided only very rough estimates of water quality. 'We were able to get accurate measurements of water clarity only after Landsat Thematic Mapper (TM) data became available,' says Lillesand. Since 1972 the Landsat program has launched a series of Earth observation satellites into orbit, collecting image data of our planet's surface. The sensors on the first three satellites in the series, launched in the 1970s, had a coarse spatial resolution (80 meters), and only four spectral bands. Later versions of Landsat have carried improved sensors-the Thematic Mapper instrument on Landsats 4 and 5, and the Enhanced Thematic Mapper Plus on the most recent of the series, Landsat 7, launched in 1999. The Thematic Mapper and the Enhanced Thematic Mapper instruments acquire images in seven different wavelengths of radiation reflected or emitted from the surface of the Earth. The wavelengths are in the visible, reflective infrared and thermal infrared parts of the spectrum. With a spatial resolution of 30 meters, the images are well suited for mapping and monitoring large features such as lakes. 'It was the higher resolution and the addition of the blue band on the Thematic Mapper that gave us clearer results,' says Lillesand. The researchers found that when the amount of blue light reflecting off of the lake was high and the red light was low, the lake generally had high water quality. 'It's common sense. When you look at a clear lake from a distance it appears blue,' says Lillesand. Lakes loaded with algae and sediments, on the other hand, reflect less blue light and more red light. He further explains that the scientists first acquired Landsat Thematic Mapper data of the lakes with known Secchi depths. They then analyzed the satellite data to see if they could arrive at an image that displayed lake clarity as accurately as the Secchi disk measurements. In the end, Lillesand and his colleagues were able to retrieve water clarity maps and measurements from the satellite imagery that were as accurate as Secchi disk measurements. For roughly ten years, this knowledge was put to little use. Then, in the late 1990s, researchers at the University of Minnesota launched a pilot project to measure the water quality of the lakes around the Minneapolis/St. Paul metropolitan area. With a single Landsat TM image, they obtained coverage of all the lakes in the seven-county region. They put the images of the lakes through an analysis similar to that developed a decade earlier and classified lake water quality measurements for over 500 lakes. They tested the Landsat water quality readings against Secchi measurements of sample lakes, and the two sets of data matched up very closely. 'With the Landsat images we ended up getting water quality measurements of 10 times as many lakes as we would have with the Secchi disk data,' says Brezonik. The Minnesota team then dusted off archived Landsat images dating back to the early 1970s and ran them through the same procedure. They found that most of the lakes around the seven-county metro area have not changed in quality over the past 25 years, with somewhat more (7 percent) increasing than decreasing (3 percent) in quality. The results proved so successful that a team of scientists led by Brezonik and Marvin Bauer, director of the University of Minnesota Remote Sensing and Geospatial Analysis Laboratory, expanded the survey to the entire state. The statewide project was funded in part by NASA's Upper Midwest Regional Earth Science Applications Center (RESAC), which was established to monitor and analyze the natural resources in the Upper Great Lakes region. For the statewide water quality map, the researchers assembled the best of two year's worth of cloud-free Landsat images taken of Minnesota. 'We were able to get water clarity readings on 100 percent of the lakes larger than 20 acres using the satellite data,' Brezonik says. Of the 12,700 bodies of water classified as lakes in Minnesota, roughly 10,000 are larger than 20 acres. Once again, the readings matched up with the Secchi disk records. 'When we put the map together, we did see a very strong north-south pattern in Minnesota,' says Brezonik. In the northeast Minnesota the lakes are very clear and the water quality is high. Moving south and southwest, the water clarity and quality diminishes. He believes there are two major reasons for this pattern. The first is that most of the farms and the people in Minnesota are in the southern half of the state. Nutrient-rich run-off from farms and urban developments has caused algae to grow. In the northeast, dense forests where fewer people live surround the lakes. He says the second reason is that the lakes in the south are generally shallower than those in the north. Deeper lakes generally absorb excess sediment and nutrients better. Though the team has not yet finished analyzing archived data from the past, Brezonik believes that the lakes have probably maintained the same level of quality over the past 15 years.

Multitemporal Thematic Mapper, Thematic Mapper Simulator, and detailed ground truth data were collected for a 9- by 11-km sample segment in Webster County, IA, in the summer of 1982. Three dates were acquired each with Thematic Mapper Simulator (June 7, June 23, and July 31) and Thematic Mapper (August 2, September 3, and October 21). The Thematic Mapper Simulator data were converted to equivalent TM count values using TM and TMS calibration data and model based estimates of atmospheric effects. The July 31, TMS image was compared to the August 2, TM image to verify the conversion process. A quantitative measure of proportion estimation variance (Fisher information) was used to evaluate the corn/soybeans separability for each TM band as a function of time during the growing season. The additional bands in the middle infrared allowed corn and soybeans to be separated much earlier than was possible with the visible and near-infrared bands alone. Using the TM and TMS data, temporal profiles of the TM principal components were developed. The greenness and brightness exhibited behavior similar to MSS greenness and brightness for corn and soybeans.

Infant feeding, particularly breastfeeding, is an important public health issue because early feeding methods have been shown to influence health throughout childhood. We investigated how social norms influence first-time mothers' decisions around feeding methods. We conducted two in-depth interviews with 11 first-time mothers, the first 3 weeks after birth and the second 3 months following birth. We analyzed interview data using a third-level, thematic analysis, using Goffman's theories of social interaction to guide our analysis. Our results highlighted several issues surrounding breastfeeding in modern society. We propose that nursing mothers are conscious of adhering to social norms of being a good mother, but must also cope with societal views about presenting normal appearances when they need to feed their babies in public.

This is a qualitative, exploratory, descriptive study, aiming to identify the perceptions of nurses regarding the leadership process and to analyze how this process takes place on the nightshift. Data collection was performed through the Focus Groups Technique, with 13 nightshift nurses of a public teaching hospital. Two categories that resulted from the thematic analysis are the focus of this article: the context of nightshift nursing work and leadership from the perception of the nightshift nurses. Teamwork is an important condition to vitalize the participatory perspective of the leadership process, given the necessary relationship of support and integration, above all in the nightshift nursing work. This exercise challenges the nurse in the solidification of a culture that promotes spaces for reflection regarding the work, integrating leadership with a learning process that is constituted through constructive bonds between the workers.

This study was developed at the Federal University of Minas Gerais Hospital with the purpose to analyze how nurses deal with the conflicts that occur in the work environment. The research was developed in two data collection stages. Authors applied a questionnaire, followed by a semi-structured interview. Data was organized according to their thematic content. According to the interviewed workers, the term conflict has a negative denotation. Some subjects pointed out the following types of conflict: intrapersonal, interpersonal and intergroup. Some of them also reported that nurses are prepared to face conflict situations using dialogue and negotiation. However, others answered that nurses are not prepared, due to professional inexperience and the lack of interaction with the team. Authors considered that these results must encourage nurses towards reflecting about their management practice.

1992-01-01

The visible and near-infrared bands of the Landsat Thematic Mapper (TM) and the Satellite Pour l'Observation de la Terre (SPOT) were analyzed to determine which band contained more spatial variability. It is important for applications that require spatial information, such as those dealing with mapping linear features and automatic image-to-image correlation, to know which spectral band image should be used. Statistical and visual analyses were used in the project. The amount of variance in an 11 by 11 pixel spatial filter and in the first difference at the six spacings of 1, 5, 11, 23, 47, and 95 pixels was computed for the visible and near-infrared bands. The results indicate that the near-infrared band has more spatial variability than the visible band, especially in images covering densely vegetated areas. -Author

The objective of this study was to analyze the use of relationship technology in care provided to patients with arterial hypertension. This is a qualitative study, conducted in eight Family Health Units from Jequié-Bahia. The study subjects were policy makers, health professionals and patients, totaling sixteen informants. Semi-structured interviews, systematic observation and documental analysis were performed in 2012. The data were submitted to thematic content analysis. Results showed that the professionals, especially nurses and community health workers, use light technology in the search for comprehensive care. On the other hand, some professionals have demonstrated biology-based practice, with emphasis on rules and procedures. It is concluded that there is a need to change professional-patient interactions, considering the uniqueness and autonomy of the patient and family in the construction of new forms of care.

To learn the forest dynamics and evaluate the ecosystem services of forest effectively, a timely acquisition of spatial and quantitative information of forestland is very necessary. Here, a new method was proposed for mapping forest cover changes by combining multi-scale satellite remote-sensing imagery with time series data. Using time series Normalized Difference Vegetation Index products derived from the Moderate Resolution Imaging Spectroradiometer images (MODIS-NDVI) and Landsat Thematic Mapper/Enhanced Thematic Mapper Plus (TM/ETM+) images as data source, a hierarchy stepwise analysis from coarse scale to fine scale was developed for detecting the forest change area. At the coarse scale, MODIS-NDVI data with 1-km resolution were used to detect the changes in land cover types and a land cover change map was constructed using NDVI values at vegetation growing seasons. At the fine scale, based on the results at the coarse scale, Landsat TM/ETM+ data with 30-m resolution were used to precisely detect the forest change location and forest change trend by analyzing time series forest vegetation indices (IFZ). The method was tested using the data for Hubei Province, China. The MODIS-NDVI data from 2001 to 2012 were used to detect the land cover changes, and the overall accuracy was 94.02 % at the coarse scale. At the fine scale, the available TM/ETM+ images at vegetation growing seasons between 2001 and 2012 were used to locate and verify forest changes in the Three Gorges Reservoir Area, and the overall accuracy was 94.53 %. The accuracy of the two layer hierarchical monitoring results indicated that the multi-scale monitoring method is feasible and reliable.

Visible to shortwave infrared radiometric data collected by a number of remote sensing instruments on aircraft and satellite platforms were compared over common areas in the First International Satellite Land Surface Climatology Project (ISLSCP) Field Experiment (FIFE) site on August 4, 1989, to assess their radiometric consistency and the adequacy of atmospheric correction algorithms. The instruments in the study included the Landsat 5 Thematic Mapper (TM), the SPOT 1 high-resolution visible (HRV) 1 sensor, the NS001 Thematic Mapper simulator, and the modular multispectral radiometers (MMRs). Atmospheric correction routines analyzed were an algorithm developed for FIFE, LOWTRAN 7, and 5S. A comparison between corresponding bands of the SPOT 1 HRV 1 and the Landsat 5 TM sensors indicated that the two instruments were radiometrically consistent to within about 5 percent. Retrieved surface reflectance factors using the FIFE algorithm over one site under clear atmospheric conditions indicated a capability to determine near-nadir surface reflectance factors to within about 0.01 at a reflectance of 0.06 in the visible (0.4-0.7 microns) and about 0.30 in the near infrared (0.7-1.2 microns) for all but the NS001 sensor. All three atmospheric correction procedures produced absolute reflectances to within 0.005 in the visible and near infrared. In the shortwave infrared (1.2-2.5 microns) region the three algorithms differed in the retrieved surface reflectances primarily owing to differences in predicted gaseous absorption. Although uncertainties in the measured surface reflectance in the shortwave infrared precluded definitive results, the 5S code appeared to predict gaseous transmission marginally more accurately than LOWTRAN 7.

As evidenced by the increasing popularity of YouTube (www.youtube.com), personal narratives shared through social media are an area of rapid development in communication among cancer survivors. Identifying the thematic and linguistic characteristics of YouTube cancer stories can provide a better understanding of this naturally occurring communication channel and inform social media communication efforts aiming to use personal stories to reach individuals with serious illnesses. The objective of our study was to provide an in-depth description of authentic personal cancer stories. Through a linguistically based narrative analysis of YouTube stories, the analysis explicates the common attributes of these narratives. Informed by narrative theories, we conducted an iterative, bottom-up analysis of 35 YouTube videos identified by the search terms "cancer survivor" and "cancer stories". A list of shared thematic and linguistic characteristics was identified and analyzed. A subnarrative on the cancer diagnosis was present in 86% (30/35) of the stories under analysis. These diagnostic narratives were characterized by dramatic tension, emotional engagement, markers of the loss of agency or control, depersonalized reference to the medical personnel, and the unexpectedness of a cancer diagnosis. The analysis highlights the themes of story authenticity and emotional engagement in this online communication medium. Internet advances have enabled new and efficient exchange of personal stories, including the sharing of personal cancer experience among cancer survivors and their caregivers. The analytic results of this descriptive study point to the common characteristics of authentic cancer survivorship stories online. Furthermore, the results of this descriptive study may inform development of narrative-based communication, particularly in maintaining authenticity and emotional engagement.

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 2011, with an overall accuracy of 0.81, compared to 0.66 for NLCD 2011. These results demonstrated that our continuous cover predictions and models were successful in increasing thematic classification accuracy in Western United States shrublands. We plan to directly use the “cross-walked” product, where available, in the NLCD 2016 product.

In this work we test the compatibility between the theoretical parameters of a nonlinear wave model and the quantitative information that one can deduce from satellite-derived data. The theoretical parameters are obtained by applying an inverse problem to the solution of the Cauchy problem for the Korteweg-de Vries equation. Our results are applied to the case of internal wave patterns elaborated from two different satellite sensors at the south of Messina (the thematic mapper) and at the north of Messina (the synthetic aperture radar).

Progress in the application of digital analysis of multispectral scanner data to agro-environmental studies is described. Simulation of LANDSAT D thematic mapper (TM) observations from aircraft multispectral scanner data and field spectrometer data collected over a corn-soybean agricultural region in Webster County, Iowa during the 1979 growing season in support of the NASA/AgRISTARS program is described. The simulations were analyzed to evaluate the potential utility of the TM (1.55-1.75 micron) mid-infrared observations in corn-soybean discrimination. Current LANDSAT data was analyzed to study snow cover in northern New England and wetlands in Nebraska and Vermont. The application of satellite remote sensor data in additional environmental research areas is described.

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 article aims to analyze the meanings upon which health promotion intervention practices are based, and the consequences of these meanings in the identification of responsibilities in health. The passage of Catalonia's Public Health Law 18/2009 facilitated the development of the Demonstrative Project of the Public Health Agency, in the framework of which fieldwork for the Plan for Health Education and Promotion in Children and Adolescents in La Garrotxa (region of Catalonia) was carried out. In this way, 20 interviews with key informants were conducted. Through a thematic analysis, it was found that the State and the individual are identified as the primary agents responsible for the production of healthy societies. It was also evidenced that, in the articulation between the discourses referring to free and rational decision-making and those referring to the social, political and economic environment, different approaches towards responsibility are construed, with effects related to the potentiation (or lack thereof) of the State as a guarantor of the population's health in opposition to blaming of the individual.

to interpret the meanings patients with type 2 diabetes mellitus assign to health education groups. ethnographic study conducted with Hyperdia groups of a healthcare unit with 26 informants, with type 2 diabetes mellitus, and having participated in the groups for at least three years. Participant observation, social characterization, discussion groups and semi-structured interviews were used to collect data. Data were analyzed through the thematic coding technique. four thematic categories emerged: ease of access to the service and healthcare workers; guidance on diabetes; participation in groups and the experience of diabetes; and sharing knowledge and experiences. The most relevant aspect of this study is the social use the informants in relation to the Hyperdia groups under study. the studied groups are agents producing senses and meanings concerning the process of becoming ill and the means of social navigation within the official health system. We expect this study to contribute to the actions of healthcare workers coordinating these groups given the observation of the cultural universe of these individuals seeking professional care in the various public health care services.

Concern has been expressed about the potentially contagious effect of television soap opera suicides and suicidal language in social media. Twitter content was analyzed during the week in which a fictional assisted suicide was broadcast on a British television soap opera, "Coronation Street." Tweets were collected if they contained language indicating possible suicidal intent or used the word suicide. The modified Thompson tau method was used to test for any differences in the volume of tweets in both categories on the day of screening. Content analysis broke down the use of the word suicide into six thematic categories. There was no evidence on the day of screening of an increase in tweets expressing possible suicidal intent but there was an increase in tweets containing the word suicide. Content analysis found the most common thematic category to be information or support, followed by the raising of moral issues in relation to suicide. It is possible that for certain high-profile media events Twitter may be used more as a civic reactive forum than as a medium for introspection or disclosure of distress.

This study aims to examine the meaning and practical implications of integration of a complementary medicine-based surgery service in a hospital setting (CISS--Complementary/Integrative Surgery Service) through analysis of consultation reports associated with this service. Thematic analysis was used to evaluate CISS consultation reports in a hospital electronic consultant charting system during the first half year of the service's activity. 304 consultation reports were analyzed. Nurses initiated significantly more consultations than physicians (55% vs 7%). Consultation requests were gradually more focused on specific symptoms, possibly manifesting a better understanding of the scope of complementary medicine in the surgery setting. CISS practitioners responded in more biomedical language over time, albeit offering a more holistic perspective regarding patients' needs as well as clarifications regarding the nature of the treatment they provided. Diverse communication patterns in consultations evolved over time representing dynamics in multiple levels of integration of the CISS. Documented communication through consultations can provide a window to the process of integration of complementary medicine-based services in health systems. Copyright © 2012 Elsevier Ireland Ltd.

The lesbian, gay, bisexual, and transgender (LGBT) community is a diverse, underserved, and often stigmatized group that faces many barriers to accessing quality healthcare. Not only are few practicing physicians knowledgeable about and sensitive to the needs of LGBT patients, but medical school curricula include limited LGBT-related content. Our goals were to use LGBT-related educational sessions to gauge undergraduate medical students' interest and their perceptions of relevance and to eventually incorporate this topic into the curriculum. We provided 4 educational sessions to preclinical medical students at the Tulane University School of Medicine: 3 optional, 1-hour didactic sessions and 1 standardized patient encounter. Following sessions 1-3, students completed electronic feedback forms; we then analyzed their responses thematically. THE THEMATIC ANALYSIS OF STUDENT RESPONSES IDENTIFIED KEY THEMES: a current lack of exposure to LGBT content, agreement that LGBT material is applicable to students' work as future physicians, and the relevance of including such information in the medical school curriculum. The study validated the underlying assumption that LGBT educational sessions are meaningful to and valued by medical students.

This study integrates the application of Dempster-Shafer-driven evidential belief function (DS-EBF) methodology with remote sensing and geographic information system techniques to analyze surface and subsurface data sets for the spatial prediction of groundwater potential in Perak Province, Malaysia. The study used additional data obtained from the records of the groundwater yield rate of approximately 28 bore well locations. The processed surface and subsurface data produced sets of groundwater potential conditioning factors (GPCFs) from which multiple surface hydrologic and subsurface hydrogeologic parameter thematic maps were generated. The bore well location inventories were partitioned randomly into a ratio of 70% (19 wells) for model training to 30% (9 wells) for model testing. Application results of the DS-EBF relationship model algorithms of the surface- and subsurface-based GPCF thematic maps and the bore well locations produced two groundwater potential prediction (GPP) maps based on surface hydrologic and subsurface hydrogeologic characteristics which established that more than 60% of the study area falling within the moderate-high groundwater potential zones and less than 35% falling within the low potential zones. The estimated uncertainty values within the range of 0 to 17% for the predicted potential zones were quantified using the uncertainty algorithm of the model. The validation results of the GPP maps using relative operating characteristic curve method yielded 80 and 68% success rates and 89 and 53% prediction rates for the subsurface hydrogeologic factor (SUHF)- and surface hydrologic factor (SHF)-based GPP maps, respectively. The study results revealed that the SUHF-based GPP map accurately delineated groundwater potential zones better than the SHF-based GPP map. However, significant information on the low degree of uncertainty of the predicted potential zones established the suitability of the two GPP maps for future development of groundwater resources in the area. The overall results proved the efficacy of the data mining model and the geospatial technology in groundwater potential mapping.

Forests within the New England states and Canadian Maritime provinces, here described as the Acadian New England (ANE) forests, have undergone substantial disturbances due to insect, fire, and anthropogenic factors. Through repeated satellite observations captures by USGS's Landsat program, 45 years of disturbance information can be incorporated into modeling efforts to better understand the spatial and temporal trends in forest above ground biomass (AGB). Using Google's Earth Engine, annual mosaics were developed for the ANE study area and then disturbance and recovery metrics were developed using the temporal segmentation algorithm VeRDET. Normalization procedures were developed to incorporate the Landsat Multispectral Scanner (MSS, 1972 - 1985) data alongside the modern era of Landsat Thematic Mapper (TM, 1984-2013), Enhanced Thematic Mapper plus (ETM+, 1999 - present), and Operational Land Imager (OLI, 2013- present) data products. This has enabled the creation of a dataset with an unprecedented spatial and temporal view of forest landscape change. Model training was performed using was the Forest Inventory Analysis (FIA) and New Brunswick Permanent Sample Plot data datasets. Modeling was performed using parametric techniques such as mixed effects models and non-parametric techniques such as k-NN imputation and generalized boosted regression. We compare the biomass estimate and model accuracy to other inventory and modeling studies produced within this study area. The spatial and temporal patterns of stock changes are analyzed against resource policy, land ownership changes, and forest management.

It is thought that semantic memory represents taxonomic information differently from thematic information. This study investigated the neural basis for the taxonomic-thematic distinction in a unique way. We gathered picture-naming errors from 86 individuals with poststroke language impairment (aphasia). Error rates were determined separately for taxonomic errors (“pear” in response to apple) and thematic errors (“worm” in response to apple), and their shared variance was regressed out of each measure. With the segmented lesions normalized to a common template, we carried out voxel-based lesion-symptom mapping on each error type separately. We found that taxonomic errors localized to the left anterior temporal lobe and thematic errors localized to the left temporoparietal junction. This is an indication that the contribution of these regions to semantic memory cleaves along taxonomic-thematic lines. Our findings show that a distinction long recognized in the psychological sciences is grounded in the structure and function of the human brain. PMID:21540329

Spectral characterization of biophysical characteristics in a boreal forest - Relationship between Thematic Mapper band reflectance and leaf area index for Aspen

Results from analysis of a data set of simultaneous measurements of Thematic Mapper band reflectance and leaf area index are presented. The measurements were made over pure stands of Aspen in the Superior National Forest of northern Minnesota. The analysis indicates that the reflectance may be sensitive to the leaf area index of the Aspen early in the season. The sensitivity disappears as the season progresses. Based on the results of model calculations, an explanation for the observed relationship is developed. The model calculations indicate that the sensitivity of the reflectance to the Aspen overstory depends on the amount of understory present.

Attention-deficit hyperactivity disorder (ADHD) persists into adolescence and adulthood; however, few studies have analyzed the experiences of university students with ADHD. This study explored the difficulties experienced by university students with ADHD symptoms. Between December 2015 and February 2016, face-to-face interviews were conducted with 12 university students with self-reported ADHD symptoms. Data were analyzed using thematic analysis. Difficulties in university life were classified into four main themes (lack of daily routine, unsatisfactory academic performance and achievement, reduced interpersonal skills, and continuing worries) and analyzed. University students with ADHD symptoms had difficulties coping with repeated cycles of negative thoughts and worries, irregular lifestyles due to poor time management, dissatisfaction with academic performance and interpersonal relationships, self-dissatisfaction, and decreased self-esteem. To improve their university experience, students with ADHD should receive education about ways to stop worrying, to express emotions healthily, and to manage time efficiently.

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.

Learning to write in science: A study of English language learners' writing experience in sixth-grade science classrooms

NASA Astrophysics Data System (ADS)

Qi, Yang

Writing is a predictor of academic achievement and is essential for student success in content area learning. Despite its importance, many students, including English language learners (ELLs), struggle with writing. There is thus a need to study students' writing experience in content area classrooms. Informed by systemic functional linguistics, this study examined 11 ELL students' writing experience in two sixth grade science classrooms in a southeastern state of the United States, including what they wrote, how they wrote, and why they wrote in the way they did. The written products produced by these students over one semester were collected. Also collected were teacher interviews, field notes from classroom observations, and classroom artifacts. Student writing samples were first categorized into extended and nonextended writing categories, and each extended essay was then analyzed with respect to its schematic structure and grammatical features. Teacher interviews and classroom observation notes were analyzed thematically to identify teacher expectations, beliefs, and practices regarding writing instruction for ELLs. It was found that the sixth-grade ELLs engaged in mostly non-extended writing in the science classroom, with extended writing (defined as writing a paragraph or longer) constituting roughly 11% of all writing assignments. Linguistic analysis of extended writing shows that the students (a) conveyed information through nouns, verbs, adjectives, adverbial groups and prepositional phrases; (b) constructed interpersonal context through choices of mood, modality, and verb tense; and (c) structured text through thematic choices and conjunctions. The appropriateness of these lexicogrammatical choices for particular writing tasks was related to the students' English language proficiency levels. The linguistic analysis also uncovered several grammatical problems in the students' writing, including a limited range of word choices, inappropriate use of mood, inconsistency of verb tense, and overuse of reiterating thematic patterns and everyday conjunctions to structure and organize their writing. Thematic analysis of teacher interviews and classroom observations revealed that the teachers (a) held different expectations for English language learners than mainstream students, (b) rarely provided explicit instruction on science writing, and (c) did not see themselves as having a shared responsibility of teaching writing in their subject area, despite acknowledgement of the essential role that writing plays in promoting scientific literacy. These findings provide a snapshot of the writing experience that sixth-grade English language learners had in their science classrooms. They suggest that the ELLs needed language and literacy support in science learning, but such support was largely absent in the science classrooms. The implications of the findings for science teaching and teacher education, along with the limitations of the study, are discussed.

Predicting a roadkill hotspots based on spatial distribution of Korean water deer (Hydropotes inermis argyropus) using Maxent model in South Korea Expressway : In Case of Cheongju-Sangju Expressway

NASA Astrophysics Data System (ADS)

Road construction has direct and indirect effects on ecosystems. Especially wildlife-vehicle conflicts (roadkills) caused by roads are a considerable threat for population of many species. This study aims to identify the effects of topographic characteristics and spatial distribution of Korean water deer (Hydropotes inermis). Korean water deer is indigenous and native species in Korea that listed LC (least concern) by IUCN redlist categories. Korean water deer population is growing every year occupying for most of roadkills (>70%) in Korean express highway. In order to predict a distribution of the Korean water deer, we selected factors that most affected water deer's habitat. Major habitats of waterdeer are known as agricultural area, forest area and water. Based on this result, eight factors were selected (land cover map, vegetation map, age class of forest, diameter class of tree, population, slope of study site, elevation of study site, distance of river), and made a thematic map by using GIS program (ESRI, Arc GIS 10.3.1 ver.). To analyze the affected factors of waterdeer distribution, GPS data and thematic map of study area were entered into Maxent model (Maxent 3.3.3.k.). Results of analysis were verified by the AUC (Area Unit Curve) of ROC (Receiver Operating Characteristic). The ROC curve used the sensitivity and specificity as a reference for determining the prediction efficiency of the model and AUC area of ROC curve was higher prediction efficiency closer to '1.' Selecting factors that affected the distribution of waterdeer were land cover map, diameter class of tree and elevation of study site. The value of AUC was 0.623. To predict the water deer's roadkills hot spot on Cheongju-Sangju Expressway, the thematic map was prepared based on GPS data of roadkill spots. As a result, the topographic factors that affected waterdeer roadkill were land cover map, actual vegetation map and age class of forest and the value of AUC was 0.854. Through this study, we could identify the site and hot spots that water deer frequently expected to use based on quantitative data on the spatial and topographic factors. Therefore, we can suggest ways to minimize roadkills by selecting the hot spots and by suggesting construction of eco-corridors. This study will significantly enhance human-wildlife conflicts by identifying key habitat areas for wild mammals.

A series of experiments were initiated to determine the feasibility of using thematic mapper spectral data to estimate wetlands biomass. The experiments were conducted using hand-held radiometers simulating thematic mapper wavebands 3, 4 and 5. Spectral radiance data were collected from the ground and from a low altitude aircraft in an attempt to gain some insight into the potential utility of actual thematic mapper data for biomass estimation in wetland plant communities. In addition, radiative transfer models describing volume reflectance of eight water column containing submerged aquatic vegetation were refined.

ABSTRACT Objective: to analyze managers and professionals' perceptions on the changes in hospital management deriving from accreditation. Method: descriptive study with qualitative approach. The participants were five hospital quality managers and 91 other professionals from a wide range of professional categories, hierarchical levels and activity areas at four hospitals in the South of Brazil certified at different levels in the Brazilian accreditation system. They answered the question "Tell me about the management of this hospital before and after the Accreditation". The data were recorded, fully transcribed and transported to the software ATLAS.ti, version 7.1 for access and management. Then, thematic content analysis was applied within the reference framework of Avedis Donabedian's Evaluation in Health. Results: one large family was apprehended, called "Management Changes Resulting from the Accreditation: perspectives of managers and professionals" and five codes, related to the management changes in the operational, structural, financial and cost; top hospital management and quality management domains. Conclusion: the management changes in the hospital organizations resulting from the Accreditation were broad, multifaceted and in line with the improvements of the service quality. PMID:28301031

Introduction Employee satisfaction is considered to be an important component in the promotion of service quality and increased efficiency and effectiveness in the reform plan for a healthcare system. Neglecting this issue could result in a lack of success in achieving the healthcare system’s objectives. The healthcare reform plan is being implemented to achieve the objectives of the healthcare system. Thus, given the key role of hospital employees in implementing the reform plan, the aim of this study was to determine the levels of hospital employees’ satisfaction with their jobs. Methods This was a qualitative study in 2015 that included thematic analysis, and 138 employees of the Kosar, Rajaii, and Ghods Hospitals participated. Data were collected using semi-structured interviews, and the data were analyzed using content analysis. Results After analyzing the data collected by interviewing the employees, 132 codes were identified. The codes were classified into five general concepts including opinions about 1) the reform plan and its administrative barriers, 2) changes in visits, 3) changes in working conditions, 4) changes in salaries and 5) General satisfaction of personnel. Conclusion Increasing workloads, stagnant salaries, and the shortage of personnel were the main factors that reduced the satisfaction of the hospitals’ employees with the administration of the healthcare reform plan.

Korngiebel, Diane M; West, Kathleen M; Burke, Wylie

2018-04-01

Test results for genetic conditions, such as Lynch Syndrome (LS), have traditionally been returned by genetic counselors or other providers who can explain results implications and provide psychosocial support. Returning genetic results through an Electronic Health Record's patient portal may increase the efficiency of returning results and could activate patient follow-up; however, stakeholder input is necessary to determine acceptability and appropriate implementation for LS. Twenty interviews were conducted with clinicians from six specialties involved in LS screening that represent a range of settings. Data were analyzed using directed content analysis and thematic analysis across content categories. Participants felt that patient portals could supplement personal calls, but the potential sensitive nature of LS screening results indicated the need for caution. Others felt that LS results could be returned through portals if there were clear explanations of the result, reputable additional information available within the portal, urging follow up confirmatory testing, and a referral to a genetics specialist. Patient portals were seen as helpful for prompting patient follow-up and providing resources to notify at-risk family members. There is potential for patient portals to return LS screening and other genetic results, however we raise several issues to resolve before implementation is warranted.

The author has identified the following significant results. The analysis of strip mining from ERTS-1 data has resulted in the mapping of landscape changes for the Cumberland Plateau Test Site. Several mapping experiments utilizing ERTS-1 data have been established for the mapping of state-wide land use regions. The first incorporates 12 frames of ERTS-1 imagery for the generalized thematic mapping of forest cover for the state of Tennessee. In another mapping effort, 14 ERTS-1 images have been analyzed for plowed ground signatures to produce a map of agricultural regions for Tennessee, Kentucky, and the northern portions of Mississippi and Alabama. Generalized urban land use categories and transportation networks have been determined from ERTS-1 imagery for the Knoxville Test Site. Finally, through the analysis of ERTS-1 imagery, short-lived phenomena such as the 1973 spring floods on the Mississippi River in western Tennessee, have been detected, monitored, and mapped.

2016-01-01

Background Outsourcing labor is linked to negative impacts on occupational health and safety (OHS). In British Columbia, Canada, provincial health care service providers outsource support services such as cleaners and food service workers (CFSWs) to external contractors. Objectives This study investigates the impact of outsourcing on the occupational health safety of hospital CFSWs through a mixed methods approach. Methods Worker’s compensation data for hospital CFSWs were analyzed by negative binomial and multiple linear regressions supplemented by iterative thematic analysis of telephone interviews of the same job groups. Results Non-significant decreases in injury rates and days lost per injury were observed in outsourced CFSWs post outsourcing. Significant decreases (P < 0.05) were observed in average costs per injury for cleaners post outsourcing. Outsourced workers interviewed implied instances of underreporting workplace injuries. Conclusions This mixed methods study describes the impact of outsourcing on OHS of healthcare workers in British Columbia. Results will be helpful for policy-makers and workplace regulators to assess program effectiveness for outsourced workers. PMID:27696988

Participation in the Paralympic Games has grown substantially, yet the same growth and development has not occurred with empirical literature for coaching in disability sport. The purpose of the current study was to explore Paralympic coaches' perceptions of their learning and educational experiences, including their formal and informal mentoring opportunities. Six highly successful and experienced Paralympic coaches were individually interviewed in this qualitative study. The interview data were analyzed following Braun and Clarke's guidelines for thematic analysis. Results demonstrated that Paralympic coaches faced several challenges to acquire disability specific coaching knowledge and skills. These challenges led the participants to utilize an array of informal learning situations, such as actively seeking mentoring relationships when they first entered the field. After becoming expert coaches, they gave back to their sport by making mentoring opportunities available for aspiring coaches. The results of the current study address the value and importance of mentoring as a structured source of education and career development for aspiring Paralympic coaches. Crown Copyright © 2016.

2013-01-01

Objectives In group interviews, we examined strategies used to manage chronic pain from the perspective of the individual. Methods Sixteen low income overweight Latino adults participated in two group interviews facilitated by a trained moderator who inquired about the type of chronic pain suffered by participants, followed by more specific questions about pain management. Interviews were audio-recorded, transcribed verbatim (Spanish), back-translated into English, and analyzed using thematic analysis. Results Participants’ pain varied in type, location, and intensity. Participants discussed pain-related changes in activities and social life, and difficulties with health care providers, and as a result, we discovered five major themes: Pain-related Life Alterations, Enduring the Pain, Trying Different Strategies, Emotional Suffering, and Encounters with Health Care System/Providers. Discussion Findings indicated that there are opportunities for providers to improve care for low income overweight Latinos with chronic pain by listening respectfully to how pain alters their daily lives and assisting them in feasible self management strategies.

ABSTRACT Background: Violence against women (VAW) is a central issue in gender studies and one that has united feminist activists from around the world. But this does not mean that this struggle is singular: indeed, one can say that there are many, diverse and sometimes even contradictory struggles occurring throughout the world. Objectives: To identify and analyze the different struggles faced by women from Roma organizations in Spain in relation to VAW and their work with affected women. Methods: Twelve semi-structured interviews were conducted among women actively involved in Roma associations in different Spanish cities, in 2015. An inductive thematic analysis was used to analyze the empirical materials. Results: Our analysis resulted in three themes that captured different struggles that women from Roma organizations have faced: ‘between persistence and rupture of restrictive gender norms’, ‘invisibility and normalization of violence against women’ and ‘willingness and trust in daily work with women’. The activities related to VAW carried out by the interviewed women were more related to their personal initiatives and abilities than to strategies proposed by the organizations they work for. Conclusions: The results show the need to support the initiatives of Romani women and their own struggles related to identity. This is what makes them true promoters of social change and, more specifically, change related to gender relations both within and outside of their communities. PMID:28585896

What versus where: Investigating how autobiographical memory retrieval differs when accessed with thematic versus spatial information.

PubMed

Sheldon, Signy; Chu, Sonja

2017-09-01

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.

SUVI Thematic Maps: A new tool for space weather forecasting

NASA Astrophysics Data System (ADS)

Hughes, J. M.; Seaton, D. B.; Darnel, J.

2017-12-01

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.

2016-01-01

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.

The selection of observation of vegetation is the primary optimization objective of the thematic mapper. The following are aspects of plans for the thematic mapper: (1) to include an appropriately modified first generation MSS in the thematic mapper mission; (2) to provide assured coverage for a minimum of six years to give agencies and other users an opportunity to justify the necessary commitment of resources for the transition into a completely valid operational phase; (3) to provide for global, direct data read-out, without the necessity for on-board data storage or dependence on foreign receiving stations; (4) to recognize the operational character of the thematic mapper after successful completion of its experimental evaluation; and (5) to combine future experimental packages with compatible orbits as part of the operational LANDSAT follow-on payloads.

In 1981, NASA conducted with an American company a cooperative study, involving the use of Thematic Mapper Simulator (TMS) data. The study was concerned with an area near Crested Butte, Colorado, which contains a known, but unmined, major molybdenum deposit. Detailed ground observations in the Mt. Emmons area demonstrated that the imagery was extremely effective for detection of geologically significant features. The imagery specifically delineated areas of ferric iron staining, seritization, and hornfelized rock. Attention is given to data acquisition and data processing, field work in 1982 and in 1983, the integration of gravity data, and costs.

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.

The objectives of this study were to study maternal preferences for the return of their child's genetic results and to describe the experiences, perceptions, attitudes, and values that are brought to bear when individuals from different racial and cultural backgrounds consider participating in genetic research. We recruited women with diverse sociodemographic profiles to participate in seven focus groups. Twenty-eight percent of participants self-identified as Hispanic; 49% as White, non-Hispanic; and 21% as Asian or Asian American. Focus groups were conducted in English or Spanish and were audio-recorded and transcribed verbatim. Transcripts were analyzed using qualitative thematic methods. Results indicated that preferences and decisions regarding the return of results may depend on both research and individual contextual factors. Participants understood the return of results as a complex issue, where individual and cultural differences in preferences are certain to arise. Another key finding was that participants desired an interpersonal, dynamic, flexible process that accommodated individual preferences and contextual differences for returning results. Our findings indicate a need to have well-developed systems for allowing participants to make and change over time their choices regarding the return of their child's genetic results.

2012-01-01

Results of an exploratory study are presented which examined workforce challenges in Australia's most established psychiatric rehabilitation sector. The study had the two-fold aim of investigating workforce challenges at an organizational ("meso") level and at the level of direct-service workers' daily practice ("micro"). Data from 23 key informant interviews conducted with service managers and long-serving staff were analyzed through basic descriptive and thematic analyses. Organizations faced significant annual staff turnover (25.6%), specific staff supply shortages, and challenges in recruiting staff with adequate experience and longevity to match the complexity of client issues. Workers equally encountered challenges in this increasingly complex and rapidly changing field of work. CONCLUSIONS & IMPLICATIONS FOR PRACTICE: Workforce strategies designed to attract/retain experienced staff can improve workforce cohesiveness and sustainability, as can training and support activities aimed at equipping staff to reflect on and operate in dynamic and changing work environments.

2018-02-01

In this article, we report the results of research that explores the intra-mathematical connections that high school students make when they solve Calculus tasks, in particular those involving the derivative and the integral. We consider mathematical connections as a cognitive process through which a person relates or associates two or more ideas, concepts, definitions, theorems, procedures, representations and meanings among themselves, with other disciplines or with real life. Task-based interviews were used to collect data and thematic analysis was used to analyze them. Through the analysis of the productions of the 25 participants, we identified 223 intra-mathematical connections. The data allowed us to establish a mathematical connections system which contributes to the understanding of higher concepts, in our case, the Fundamental Theorem of Calculus. We found mathematical connections of the types: different representations, procedural, features, reversibility and meaning as a connection.

This article examines the processes of technical mediation within familial care networks based on a study of home telecare targeted at older people. Supported by contributions from the actor-network theory as part of the social psychology of science and technology, these processes of technical mediation are analyzed using a qualitative approach. The data were gathered through six focus groups and four in-depth interviews; the participants in the study included users, relatives and formal carers. Thematic analysis techniques encompassing the information were used, revealing the effects on the patterns of caring relationships. The results show the interplay between presence-absence made possible by the devices; the two-way direction of care between the older people and the artifacts; and the process of sustaining care using the technology. We conclude that care should be seen as a socio-technical network where technology plays an active role in sustaining family relationships.

A total of 19 semi-structured interviews were conducted with the drug addicts' family members in treatment. The results were analyzed based on the Transtheoretical Model of Behavior Change and organized in thematic categories according with qualitative data analysis. the search for treatment for drug addicts occurred: in the pre-contemplation stage influenced by external factors; in the contemplation stage both for ambivalence and behavioral changes needs; in the action stage by awareness of drug addiction and also professional help needs; and in the maintenance stage because of the non-conservation of behavioral changes. an evaluation of motivational stages in the beginning of treatment is required for expansion of success possibilities in the rehabilitation process.

Facilitator control as automatic behavior: A verbal behavior analysis

PubMed Central

Hall, Genae A.

1993-01-01

Several studies of facilitated communication have demonstrated that the facilitators were controlling and directing the typing, although they appeared to be unaware of doing so. Such results shift the focus of analysis to the facilitator's behavior and raise questions regarding the controlling variables for that behavior. This paper analyzes facilitator behavior as an instance of automatic verbal behavior, from the perspective of Skinner's (1957) book Verbal Behavior. Verbal behavior is automatic when the speaker or writer is not stimulated by the behavior at the time of emission, the behavior is not edited, the products of behavior differ from what the person would produce normally, and the behavior is attributed to an outside source. All of these characteristics appear to be present in facilitator behavior. Other variables seem to account for the thematic content of the typed messages. These variables also are discussed.

Objective The purpose of this qualitative study was to explore the experiences of youth with Tourette Syndrome (TS). Method Thirteen participants with TS were recruited from a large tertiary care hospital to complete semi-structured interviews and two questionnaires pertaining to demographic information and tic severity. Thematic analysis was utilized to systematically analyze the data. Results Three main themes were identified: 1) beliefs about TS; 2) TS related distress and impairment; and, 3) coping with TS. Conclusion The findings from this study suggest that most participants were aware of their tics but unaware of the cause of tics/TS. The interviews also highlighted that, for most participants, TS caused emotional, social, physical, and/or occupational impairment. Despite their distress, participants provided several suggestions for coping with TS and for supporting those who are diagnosed with this condition. PMID:28331502

This study aims to determine the characteristics of students who were uninterested in attending practicum classes. This study applied naturalistic qualitative research methods using participatory observation and interviews. The data validity was ensured by triangulation, detailed description, length of observation time, as well as details and thorough observation. The data were analyzed using domain analysis and followed by conducting taxonomic, component, and thematic analyses. The results of the study indicate that faineant students show a negative behavior while attending laboratory practicums. They have a lack of motivation, effective interaction, and attention. The cognitive abilities vary from low to high. Other causes on how the aspects of the study were low were found as well, therefore improving those aspects allows students to raise their interest in practicum classes. The impact is to create well-skilled vocational teachers in conducting practicum classes in vocational schools and to make graduates better-prepared for the workforce.

A developmentally informed adaptation of minority stress for sexual minority adolescents

PubMed Central

Goldbach, Jeremy T.; Gibbs, Jeremy J.

2017-01-01

Sexual minority adolescents (lesbian, gay, bisexual) experience disparities in behavioral health outcomes compared to their heterosexual peers, generally attributed to minority stress. Although evidence of the applicability of the minority stress model among adolescents exists, it is based on a primarily adult literature. Developmental and generational differences demand further examination of minority stress to confirm its applicability. Forty-eight life history interviews with sexual minority adolescents in California (age 14–19; M=19.27 SD = 1.38; 39.6% cismale, 35.4% cisfemale, 25% other gender) were completed, recorded, transcribed, and analyzed using thematic analysis in QSR NVivo. Following a consensus model, all transcripts were double coded. Results suggest that minority stress is appropriate for use with adolescents; however, further emphasis should be placed on social context, coping resources, and developmental processes regarding identity development. A conceptual model is provided, as are implications for research and practice. PMID:28033502

Care Networking: A Study of Technical Mediations in a Home Telecare Service

Correa, Gonzalo; Domènech, Miquel

2013-01-01

This article examines the processes of technical mediation within familial care networks based on a study of home telecare targeted at older people. Supported by contributions from the actor—network theory as part of the social psychology of science and technology, these processes of technical mediation are analyzed using a qualitative approach. The data were gathered through six focus groups and four in-depth interviews; the participants in the study included users, relatives and formal carers. Thematic analysis techniques encompassing the information were used, revealing the effects on the patterns of caring relationships. The results show the interplay between presence-absence made possible by the devices; the two-way direction of care between the older people and the artifacts; and the process of sustaining care using the technology. We conclude that care should be seen as a socio-technical network where technology plays an active role in sustaining family relationships. PMID:23880730

Environmental imbalance due to human activities has shown serious threat to ecosystem and produced negative impacts. The main goal of this study is to identify, monitor and classify temporal changes of forest cover, build up and open spaces in Margalla Hills National Park, Islamabad. Geographic Information Sciences (GISc) and Remote Sensing (RS) techniques has been used for the assessment of analysis. LANDSAT-7 Enhanced Thematic Mapper (ETM+) and LANDSAT-8 Operational Land Imager (OLI) were utilized for obtaining data of year 2000 and 2018. Temporal changes were evaluated after applying supervised classification and discrimination was analyzed by Per-Pixel based change detection. Results depicts forest cover decrease from 87 % to 74 % whereas build up has increased from 5 % to 7 % over the span. Consequences also justify the presence of open land in study area that has been increased from 2 % to 7 % respectively.

Two image processing experiments are described using a MSS-LANDSAT scene from the Tres Marias region and a shuttle Imaging Radar SIR-A image digitized by a vidicon scanner. In the first experiment the study area is analyzed using the original and preprocessed SIR-A image data. The following thematic classes are obtained: (1) water, (2) dense savanna vegetation, (3) sparse savanna vegetation, (4) reforestation areas and (5) bare soil areas. In the second experiment, the SIR-A image was registered together with MSS-LANDSAT bands five, six, and seven. The same five classes mentioned above are obtained. These results are compared with those obtained using solely MSS-LANDSAT data. The spatial information as well as coregistered SIR-A and MSS-LANDSAT data can increase the separability between classes, as compared to the use of raw SIR-A data solely.

Although education is central to HIV testing and counseling, little is known about the educational processes within the testing experience. This study investigated test providers' understandings of testing and counseling best practices. Interviews with a purposive sample of 24 test providers were thematically analyzed. Analysis revealed five best practices specific to HIV education and public health--ensuring information and education for HIV risk reduction, individualization of risk assessment, ensuring test results are given in person, providing information and referrals, and facilitating partner notification--and six practices not specific to HIV counseling relationship building. The latter were building trust and rapport; maintaining professional boundaries; ensuring a comfortable, safe environment; ensuring confidentiality; imparting nonjudgmntal attitude; and self-determination. The identified best practices demonstrated remarkable consistency across respondent subgroups. Although counseling was seen as largely educational and with a preventive focus, it included individualized messages based on assessments of risk, knowledge, and social and cultural characteristics.

2012-06-01

The aim of this study was to describe and analyze the storytelling of children with emotional difficulties. Forty children with emotional and relational difficulties (inhibited and impulsive), ages between 5.5 and 9.4 years old, were assessed by a multiaxial procedure and the bears family projective test. The bears family test is a constructive-thematic-projective method based on an anthropomorphic family of bears that children can manipulate to tell a story. The stories of 40 children without emotional difficulties (matched by IQ, socio-economic status, and gender) and 322 typically developing children, aged between four and 10 years old, were used as a reference for comparisons. Results indicated that the stories of children with emotional difficulties showed many unsolved problematic events, unclear characters, negative relationships, and negative behaviors. Unlike the stories of children without emotional difficulties, positive contents didn't prevail over negative, and there wasn't a positive compensation for negative elements.

Teachers need various types of knowledge in order to deliver various fraction concepts at elementary level. In this paper, Balls' framework (2008) or, Mathematical Knowledge for Teaching (MKT) is used as benchmark guideline. This paper investigates and explores component of MKT knowledge among eight experienced teachers of the primary school. Data was collected using paper pencil test, interview and video recording. This paper, narrowed to teacher's knowledge and their practices while teaching of various fractions concepts using diagrammatical approach in present of MKT. The data gathered from teachers were analyzed using thematic analysis techniques. The results indicated that teachers lack various components of MKT knowledge as a proposal by various researchers and assumed that teaching as procedural more than enough due to lack of deep understanding of mathematics and the various types of MKT is not required due to the present of practices in the mathematics classroom.

Parents play an important role in helping their children process and interpret significant sociohistorical events. However, little is known about how parents frame these experiences or the specific social, cultural, and civic messages they may communicate about the event. In this study, we examined self-reported communication of parents from six communities in the United States with their adolescents about the September 11, 2001 terrorist attacks. Parents' (N = 972) open-ended responses about September 11th were analyzed to assess whether communication with their adolescents occurred and for thematic content. Results revealed marked variability in parents' communication and suggest that many parents used September 11th as an opportunity to impart sociocultural, emotional, and civic messages. Identifying the diversity in parents' responses aligns with the tenets of Terror Management Theory and provides insights into the roles of parents in translating pivotal historical moments. Collectively, these findings yield important implications for civic socialization.

In 1978, the USGS began the preparation of the 11-chapter USGS Professional Paper 1386, 'Satellite Image Atlas of Glaciers of the World'. Between 1979 and 1981, optimum satellite images were distributed to a team of 70 scientists, representing 25 nations and 45 institutions, who agreed to author sections of the Professional Paper concerning either a geographic area (chapters B-K) or a glaciological topic (included in Chapter A). The scientists used Landsat 1, 2, and 3 multispectral scanner (MSS) images and Landsat 2 and 3 return beam vidicon (RBV) images to inventory the areal occurrence of glacier ice on our planet within the boundaries of the spacecrafts' coverage (between about 82? north and south latitudes). Some later contributors also used Landsat 4 and 5 MSS and Thematic Mapper, Landsat 7 Enhanced Thematic Mapper-Plus (ETM+), and other satellite images. In addition to analyzing images of a specific geographic area, each author was asked to summarize up-to-date information about the glaciers within each area and compare their present-day areal distribution with reliable historical information (from published maps, reports, and photographs) about their past extent. Because of the limitations of Landsat images for delineating or monitoring small glaciers in some geographic areas (the result of inadequate spatial resolution, lack of suitable seasonal coverage, or absence of coverage), some information on the areal distribution of small glaciers was derived from ancillary sources, including other satellite images. Completion of the atlas will provide an accurate regional inventory of the areal extent of glaciers on our planet during a relatively narrow time interval (1972-1981).

While Human Resource Managers (HRM) and line managers could play a significant role in the prevention of job-related problems and in promotion of early job-continuation, it is not clear wether the chronically ill workers are recognized as a group. Unlike some other groups, distinguished by gender, age or ethnicity, those with chronic illness are less distinct and may not be included in diversity management programs. The aim of this research is to address theory and evidence in literature about the topic, as well as to inquire whether chronic illness of the employees is 'visible' in practice. For desk research, we used a systematic search strategy involving medical, statistical, management, and social science databases (Web of Science, MedLine, Pub Med, Psych Info, etc.). Research results are based on case studies conducted with the managers and HRM of government and commercial organizations between March 2007 and October 2008 and between October 2008 and April 2009. These case studies were based on open interviews and focus group sessions (for human resource departments) which were consequently analyzed using thematical analysis. For group sessions, we used concept mapping to collect information from two groups of HRM professionals and managers. Secondary analysis included thematic and content analysis of 'best practice' organizations carried out by the Dutch organization Gatekeeper. We have discovered that the chronically ill employees are largely invisible to HRM practitioners, line managers who do not always have the right instruments for implementation of the European or national frameworks. Most practitioners are unaware of the impact of chronic illness in their organizations and in employees work life.

Patient-perceived treatment burden of chronic obstructive pulmonary disease

2017-01-01

Background While chronic morbidity and mortality from COPD is well documented, little is known about the treatment burden faced by patients with COPD. Subjects and methods Patients with severe airflow obstruction (forced expiratory volume in 1 second [FEV1] <50% predicted) representing different age-groups, sex, and number of comorbidities participated in a semistructured interview. Interviews were conducted until thematic saturation was reached. Interviews were recorded, transcribed, and analyzed thematically using an established treatment-burden framework. Results A total of 26 patients (42% male, mean age 66.7±9.8 years) with severe (n=15) or very severe (n=11) airflow limitation (mean FEV1 32.1%±9.65% predicted) were interviewed. Participants struggled with various treatment-burden domains, predominantly with changing health behaviors, such as smoking cessation and exercise. Interviewees often only ceased smoking after a major health event, despite being advised to do so earlier by a doctor. Recommended exercise regimens, such as pulmonary rehabilitation classes, were curtailed, although some patients replaced them with light home-based exercise. Interviewees had difficulty attending medical appointments, often relying on others to transport them. Overall, COPD patients indicated they were not willing to accept the burden of treatments where they perceived minimal benefit. Conclusion This study describes the substantial treatment burden experienced by patients with COPD. Medical advice may be rejected by patients if the benefit of following the advice is perceived as insufficient. Health professionals need to recognize treatment burden as a source of nonadherence, and should tailor treatment discussions to fit patients’ values and capacity to achieve optimal patient outcomes.

Prioritization of recommendations for an effective, efficient, fair, transparent, and sustainable granting of funds through a transparent, evidence-driven consensus-process involving all relevant stakeholder groups. Representatives from health and research policy, payers, patient representatives, healthcare providers, and scientists were invited to nominate participants for an electronic 3 round iterative Delphi-study to prioritize the thematic focus, requirements concerning study methods, the team of applicants, evaluation, utilization of study results, and for the selection of reviewers. Criteria considered as relevant by at least 60% of the panel (consensus definition) in the first 2 Delphi rounds were rated as facultative, preferable, or obligatory criteria for project funding. Data were analyzed descriptively. ( Datenbank Versorgungsforschung Deutschland VfD_15_003561). All invited stakeholder groups except payers participated. 34 (85%) of 40 nominated representatives participated in the Delphi-study. A total of 64 criteria were consented as relevant for project review and funding concerning the thematic focus (n=28), methodological requirements (n=13), requirements for applicants (n=4), for the evaluation (n=4), utilization (n=6), and selection of peer reviewers (n=9). It is the collective responsibility of all stakeholders to spend the designated funds as efficient and sustainable as possible. The consented recommendations shall serve decision makers as a resource for the granting of funds and the evaluation of the Innovationsfonds. © Georg Thieme Verlag KG Stuttgart · New York.

Prediction of perceptual defense from experimental stress and susceptibility to stress as indicated by thematic apperception.

PubMed

Tuma, J M

1975-02-01

The present investigation tested the hypothesis advanced by J. Inglis (1961) that perceptual defense and perceptual vigilance result from an interaction between personality differences and degrees of experimental stress. The design, which controlled for questionable procedures used in previous studies, utilized 32 introverts and 32 extraverts, half male and half female, in an experiment with a visual recognition-task. Results indicated that under low-stress conditions introverts and extraverts identified by their response to a thematic apperception task react to threatening stimuli with perceptual defense and perceptual vigilance, respectively. Under high-stress conditions, type of avoidance activity reverses; extraverts react with perceptual defense and introverts with perceptual vigilance. It was suggested that, when both personality and stress variables are controlled, results of the perceptual defense paradigm are predictable and consistent, in support of Inglis' hypothesis.

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.

Beer marketing in the United States is controlled through self-regulation, whereby the beer industry has created a marketing code and enforces its use. We performed a thematic content analysis on beer ads broadcast during a U.S. college athletic event and determined which themes are associated with violations of a self-regulated alcohol marketing code. 289 beer ads broadcast during the U.S. NCAA Men's and Women's 1999-2008 basketball tournaments were assessed for the presence of 23 thematic content areas. Associations between themes and violations of the U.S. Beer Institute's Marketing and Advertising Code were determined using generalized linear models. Humor (61.3%), taste (61.0%), masculinity (49.2%), and enjoyment (36.5%) were the most prevalent content areas. Nine content areas (i.e., conformity, ethnicity, sensation seeking, sociability, romance, special occasions, text responsibility messages, tradition, and individuality) were positively associated with code violations (p < 0.001-0.042). There were significantly more content areas positively associated with code violations than content areas negatively associated with code violations (p < 0.001). Several thematic content areas were positively associated with code violations. The results can inform existing efforts to revise self-regulated alcohol marketing codes to ensure better protection of vulnerable populations. The use of several themes is concerning in relation to adolescent alcohol use and health disparities.

Engineering students' experiences and perceptions of workplace problem solving

Pan, Rui

In this study, I interviewed 22 engineering Co-Op students about their workplace problem solving experiences and reflections and explored: 1) Of Co-Op students who experienced workplace problem solving, what are the different ways in which students experience workplace problem solving? 2) How do students perceive a) the differences between workplace problem solving and classroom problem solving and b) in what areas are they prepared by their college education to solve workplace problems? To answer my first research question, I analyzed data through the lens of phenomenography and I conducted thematic analysis to answer my second research question. The results of this study have implications for engineering education and engineering practice. Specifically, the results reveal the different ways students experience workplace problem solving, which provide engineering educators and practicing engineers a better understanding of the nature of workplace engineering. In addition, the results indicate that there is still a gap between classroom engineering and workplace engineering. For engineering educators who aspire to prepare students to be future engineers, it is imperative to design problem solving experiences that can better prepare students with workplace competency.

The objective of this study was to extend the Consequences of Screening (COS) Questionnaire for use in a lung cancer screening by testing for comprehension, content coverage, dimensionality, and reliability. In interviews, the suitability, content coverage, and relevance of the COS were tested on participants in a lung cancer screening program. The results were thematically analyzed to identify the key consequences of abnormal and false-positive screening results. Item Response Theory and Classical Test Theory were used to analyze data. Dimensionality, objectivity, and reliability were established by item analysis, examining the fit between item responses and Rasch models. Eight themes specifically relevant for participants in lung cancer screening results were identified: "self-blame,"focus on symptoms,"stigmatization,"introvert,"harm of smoking,"impulsivity,"empathy," and "regretful of still smoking." Altogether, 26 new items for part I and 16 new items for part II were generated. These themes were confirmed to fit a partial-credit Rasch model measuring different constructs including several of the new items. In conclusion, the reliability and the dimensionality of a condition-specific measure with high content validity for persons having abnormal or false-positive lung cancer screening results have been demonstrated. This new questionnaire called Consequences of Screening in Lung Cancer (COS-LC) covers in two parts the psychosocial experience in lung cancer screening. Part I: "anxiety,"behavior,"dejection,"sleep,"self-blame,"focus on airway symptoms,"stigmatization,"introvert," and "harm of smoking." Part II: "calm/relax,"social network,"existential values,"impulsivity,"empathy," and "regretful of still smoking."

Forest fires are main disturbance factor for the natural ecosystems, especially in boreal forests. Monitoring for the dynamic of forest cover regeneration in the post-fire period of ecosystem recovery is crucial to both estimation of forest stands and forest management. In this study, on the example of burnt areas of 2010 wildfires in Republic Mari El of Russian Federation we estimated post-fire dynamic of different classes of vegetation cover between 2011-2016 years with the use of time series Landsat satellite images. To validate the newly obtained thematic maps we used 80 test sites with independent field data, as well Canopus-B images of high spatial resolution. For the analysis of the satellite images we referred to Normalized Differenced Vegetation Index (NDVI) and Tasseled Cap transformation. The research revealed that at the post-fire period the area of thematic classes "Reforestation of the middle and low density" has maximum cover (44%) on the investigated burnt area. On the burnt areas of 2010 there is ongoing active process of grass overgrowing (up to 20%), also there are thematic classes of deadwood (15%) and open spaces (10%). The results indicate that there is mostly natural regeneration of tree species pattern corresponding to the pre-fire condition. Forest plantations cover only 2% of the overall burnt area. By the 2016 year the NDVI parameters of young vegetation cover were recovered to the pre-fire level as well. The overall unsupervised classification accuracy of more than 70% shows high degree of agreement between the thematic map and the ground truth data. The research results can be applied for the long term succession monitoring and management plan development for the reforestation activities on the lands disturbed by fire.

To explore the health education needs and learning preferences of female intimate partner violence (IPV) survivors in a social service agency located in South Florida, United States. An exploratory two-phase sequential mixed-methods study was completed through semistructured interviews with social service providers (n = 10), followed by a survey with predominately female IPV survivors (n = 122, 98.4%). Data obtained from interviews with social service providers were analyzed through conventional thematic content analysis. Data from interviews were used in developing a health survey completed by IPV survivors and analyzed utilizing descriptive statistics, chi-square tests and t tests. Three themes emerged from interviews including multidimensional health needs, navigating barriers to health care, and self-improvement specific to survivors of intimate partner violence. Survey results indicated that depression and self-esteem were the health education needs of highest priority. Demographic characteristics, including age and language use, were significantly associated to preferred methods of learning, p < .05. IPV survivors present with various health education needs. Current study findings can inform public health nurses in developing interventions or health-based programs for female IPV survivors in social service agency settings. © 2017 Wiley Periodicals, Inc.

A growing emphasis has been placed on providing equal opportunities for all people, particularly people with disabilities, to support participation. Barriers to participation are represented in part by physical space restrictions. This article explores the decision-making process during the construction of a new office building housing a disability-rights organization. The building project featured in this study was developed on the principles of universal design, maximal accessibility, and sustainability to support access and participation. A qualitative case study approach was used involving collection of data through in-depth interviews with key decision-makers; non-participant observations at design meetings; and on-site tours. Qualitative thematic analysis along with the development of a classification system was used to understand specific building elements and the relevant decision processes from which they resulted. Recording and analyzing the design process revealed several key issues including grassroots involvement of stakeholders; interaction between universal design and sustainable design; addressing diversity through flexibility and universality; and segregationist accessibility versus universal design. This case study revealed complex interactions between accessibility, universal design, and sustainability. Two visual models were proposed to understand and analyze these complexities.

American Indian youth experience a greater prevalence of obesity compared with the general U.S. population. One avenue to reverse the trend toward increasing obesity prevalence is through promoting physical activity. The goal of this project was to understand tribal youths' current patterns of physical activity behavior and their beliefs and preferences about physical activity. This assessment used a community-based participatory research approach. Sample included 35 Native youth aged 8-18. A Community Advisory Board was created that specifically developed an exercise survey for this assessment to explore physical activity patterns, preferences, and determinants. Twenty-six youth completed the survey. Descriptive statistics were analyzed, exploring differences by age group. Nine youth participated in 2 focus groups. Qualitative data were analyzed with thematic analysis. Youth distinguished between sports and exercise, with each possessing different determinants. Common motivators were friends, coach, and school, and barriers were lack of programs and school or work. None of the youth reported meeting the recommended 60 min of strenuous exercise daily. This tribal academic partnership responded to a tribal concern by developing an exercise survey and conducting focus groups that addressed tribal-specific questions. The results are informing program development.

Thematic Matching as Remedial Teaching for Symbolic Matching for Individuals with Autism Spectrum Disorder

Matching-to-sample (MTS) is often used to teach symbolic relationships between spoken or printed words and their referents to children with intellectual and developmental disabilities. However, many children have difficulty learning symbolic matching, even though they may demonstrate generalized identity matching. The current study investigated whether training on symbolic MTS tasks in which the stimuli are physically dissimilar but members of familiar categories (i.e., thematic matching) can remediate an individual’s difficulty learning symbolic MTS tasks involving non-representative stimuli. Three adolescent males diagnosed with autism spectrum disorder were first trained on symbolic MTS tasks with unfamiliar, non-representative form stimuli. Thematic matching was introduced after the participants failed to learn 0, 2 or 4 symbolic MTS tasks and before additional symbolic MTS tasks were introduced. After exposure to thematic matching, accuracy on symbolic MTS tasks with novel stimuli increased to above chance for all participants. For two participants, high accuracy (> 90%) was achieved on a majority of these sessions. Thus, thematic matching may be an effective intervention for students with limited verbal repertoires and who have difficulty learning symbolic MTS tasks. Possible explanations for the facilitative effect of thematic matching are considered and warrant further investigation. PMID:24634695

Accurate delineations of irrigated acreage are needed for the development of water-use estimates and in determining water-budget calculations for the Basin and Range carbonate-rock aquifer system (BARCAS) study. Irrigated acreage is estimated routinely for only a few basins in the study area. Satellite imagery from the Landsat Thematic Mapper and Enhanced Thematic Mapper platforms were used to delineate irrigated acreage on a field-by-field basis for the entire study area. Six hundred and forty-three fields were delineated. The water source, irrigation system, crop type, and field activity for 2005 were identified and verified through field reconnaissance. These data were integrated in a geodatabase and analyzed to develop estimates of irrigated acreage for the 2000, 2002, and 2005 growing seasons by hydrographic area and subbasin. Estimated average annual potential evapotranspiration and average annual precipitation also were estimated for each field.The geodatabase was analyzed to determine the spatial distribution of field locations, the total amount of irrigated acreage by potential irrigation water source, by irrigation system, and by crop type. Irrigated acreage in 2005 totaled nearly 32,000 acres ranging from less than 200 acres in Butte, Cave, Jakes, Long, and Tippett Valleys to 9,300 acres in Snake Valley. Irrigated acreage increased about 20 percent between 2000 and 2005 and increased the most in Snake and White River Valleys. Ground-water supplies as much as 80 percent of irrigation water during dry years. Almost 90 percent of the irrigated acreage was planted with alfalfa.

Definitions, Foundations and Associations of Physical Literacy: A Systematic Review.

2017-01-01

The concept of physical literacy has stimulated increased research attention in recent years-being deployed in physical education, sport participation, and the promotion of physical activity. Independent research groups currently operationalize the construct differently. The purpose of this systematic review was to conduct a systematic review of the physical literacy construct, as reflected in contemporary research literature. Five databases were searched using the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines for systematic reviews. Inclusion criteria were English language, peer reviewed, published by March 2016, and seeking to conceptualize physical literacy. Articles that met these criteria were analyzed in relation to three core areas: properties/attributes, philosophical foundations and theoretical associations with other constructs. A total of 50 published articles met the inclusion criteria and were analyzed qualitatively using inductive thematic analysis. The thematic analysis addressed the three core areas. Under definitions, core attributes that define physical literacy were identified, as well as areas of conflict between different approaches currently being adopted. One relatively clear philosophical approach was prominent in approximately half of the papers, based on a monist/holistic ontology and phenomenological epistemology. Finally, the analysis identified a number of theoretical associations, including health, physical activity and academic performance. Current literature contains different representations of the physical literacy construct. The costs and benefits of adopting an exclusive approach versus pluralism are considered. Recommendations for both researchers and practitioners focus on identifying and clearly articulating the definitions, philosophical assumptions and expected outcomes prior to evaluating the effectiveness of this emerging concept.

Activities by NASA scientists and teachers focus on integrating Planetary Science activities with existing Earth science, math, and language arts curriculum. The wealth of activities that highlight missions and research pertaining to the exploring the solar system allows educators to choose activities that fit a particular concept or theme within their curriculum. Most of the activities use simple, inexpensive techniques that help students understand the how and why of what scientists are learning about comets, asteroids, meteorites, moons and planets. With these NASA developed activities students experience recent mission information about our solar system such as Mars geology and the search for life using Mars meteorites and robotic data. The Johnson Space Center ARES Education team has compiled a variety of NASA solar system activities to produce an annotated thematic outline useful to classroom educators and informal educators as they teach space science. An important aspect of the outline annotation is that it highlights appropriate science content information and key science and math concepts so educators can easily identify activities that will enhance curriculum development. The outline contains URLs for the activities and NASA educator guides as well as links to NASA mission science and technology. In the informal setting educators can use solar system exploration activities to reinforce learning in association with thematic displays, planetarium programs, youth group gatherings, or community events. Within formal education at the primary level some of the activities are appropriately designed to excite interest and arouse curiosity. Middle school educators will find activities that enhance thematic science and encourage students to think about the scientific process of investigation. Some of the activities offered are appropriate for the upper levels of high school and early college in that they require students to use and analyze data.

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.

While psychological care, including supportive group therapy, is a mainstay of burn treatment in the developed world, few reports of support groups for burn survivors and their caregivers in the developing world exist. This study records the findings of a support group in Malawi and provides a qualitative analysis of thematic content discussed by burn survivors and caregivers. We established a support group for burn survivors and caregivers from February-May 2012 in the burn unit at Kamuzu Central Hospital in Lilongwe, Malawi. Sessions were held weekly for twelve weeks and led by a Malawian counselor. The group leader compiled transcripts of each session and these transcripts were qualitatively analyzed for thematic information. Thematic analysis demonstrated a variety of psychological issues discussed by both survivors and caregivers. Caregivers discussed themes of guilt and self-blame for their children's injuries, worries about emotional distance now created between caregiver and survivor, fears that hospital admission meant likely patient death and concerns about their child's future and burn associated stigma. Burn survivors discussed frustration with long hospitalization courses, hope created through interactions with hospital staff, the association between mental and physical health, rumination about their injuries and how this would affect their future, decreased self-value, increased focus on their own mortality and family interpersonal difficulties. The establishment of a support group in our burn unit provided a venue for burn survivors and their families to discuss subjective experiences, as well as the dissemination of various coping techniques. Burn survivors and their caregivers in Malawi would benefit from the establishment of similar groups in the future to help address the psychological sequelae of burns.

A preliminary evaluation of LANDSAT-4 thematic mapper data for their geometric and radiometric accuracies

NASA Technical Reports Server (NTRS)

Podwysocki, M. H.; Bender, L. U.; Falcone, N.; Jones, O. D.

1983-01-01

Some LANDSAT thematic mapper data collected over the eastern United States were analyzed for their whole scene geometric accuracy, band to band registration and radiometric accuracy. Band ratio images were created for a part of one scene in order to assess the capability of mapping geologic units with contrasting spectral properties. Systematic errors were found in the geometric accuracy of whole scenes, part of which were attributable to the film writing device used to record the images to film. Band to band registration showed that bands 1 through 4 were registered to within one pixel. Likewise, bands 5 and 7 also were registered to within one pixel. However, bands 5 and 7 were misregistered with bands 1 through 4 by 1 to 2 pixels. Band 6 was misregistered by 4 pixels to bands 1 through 4. Radiometric analysis indicated two kinds of banding, a modulo-16 stripping and an alternate light dark group of 16 scanlines. A color ratio composite image consisting of TM band ratios 3/4, 5/2, and 5/7 showed limonitic clay rich soils, limonitic clay poor soils, and nonlimonitic materials as distinctly different colors on the image.

Patients who initiated treatment for multidrug-resistant tuberculosis (MDR-TB) at 15 Programmatic Management of Drug-resistant Tuberculosis (PMDT) health facilities in the Philippines between July and December 2012. To describe patients' views of current interventions, and suggest changes likely to reduce MDR-TB loss to follow-up. In-depth interviews were conducted between April and July 2014 with MDR-TB patients who were undergoing treatment, had finished treatment at the time of the interview (controls), or had been lost to follow-up (LTFU). Responses were thematically analyzed. Interviews were conducted with 182 patients who were undergoing or had completed treatment and 91 LTFU patients. Views and suggestions could be thematically categorized as approaches to facilitate adherence or address barriers to adherence. The top themes were the need for transportation assistance or improvements to the current transportation assistance program, food assistance, and difficulties patients encountered related to their medications. These themes were addressed by respectively 63%, 60%, and 32% of the participants. A more patient-centered approach is needed to improve MDR-TB treatment adherence. Programs should strive to provide assistance that considers patient preferences, is adequate to cover actual costs or needs, and is delivered in a timely, uninterrupted manner.

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.

This study explores the recruitment and retention conditions influencing primary health care (PHC) human resources for health (HRH) in Qatar and suggests strategies for their improvement. A qualitative design employing semistructured key informant interviews with PHC stakeholders in Qatar was utilized. Key interviewees were originally recognized, and snowball sampling was used to identify additional interviewees until reaching saturation point. Interview scripts were transcribed and then analyzed thematically using the Nvivo software package. Thematic analysis precipitated a number of themes. Under recruitment, the centrality of enhancing collaboration with academic institutions, enhancing extrinsic benefits, and strengthening human resources recruitment and management practices. Dedicated support needs to be provided to expatriate HRH especially in regard to housing services, children schooling, and streamlining administrative processes for relocation. Findings revealed that job security, continuous professional development, objective performance appraisal systems, enhanced job transparency, and remuneration are key retention concerns. The study provides a number of recommendations for the proper recruitment and retention of HRH. Health planners and decision makers must take these recommendations into consideration to ensure the presence of a competent and sustainable HRH in the PHC sector in the future. PMID:28853314

To understand how individuals with diabetes evaluate the participation of their family in their health care. This was a descriptive study with a qualitative approach involving 26 individuals in the Diabetes Association of Maringá. Participating in the study were 9 women and 17 men (age range, 38 to 83 years) who had attended at least one educational meeting of the "culture circles" of the association. We used the methodological reference of Paulo Freire for implementing an educational proposal directed at persons with type 2 diabetes mellitus that overcame the limitations of conventional health education approaches. Data were collected between May and July 2011. Testimonials given in meetings were recorded, transcribed, and analyzed according to thematic structures. Three thematic structures appeared: 1) Recognizing the importance of family in the care of patients with diabetes, 2) blaming the family for non-adherence to healthy practices, and 3) perceiving a secondary gain of the disease: feeling cared for by family members. Patients with diabetes perceive family as a source of support and stimulus for adherence and healthy practice, which enable them to control the disease. Family participation in a patient's care plan should be encouraged.

Application of Thematic Mapper data to corn and soybean development stage estimation

1985-01-01

A model, utilizing direct relationship between remotely sensed spectral data and the development stage of both corn and soybeans has been proposed and published previously (Badhwar and Henderson, 1981; and Henderson and Badhwar, 1984). This model was developed using data acquired by instruments mounted on trucks over field plots of corn and soybeans as well as satellite data from Landsat. In all cases, the data was analyzed in the spectral bands equivalent to the four bands of Landsat multispectral scanner (MSS). In this study the same model has been applied to corn and soybeans using Landsat-4 Thematic Mapper (TM) data combined with simulated TM data to provide a multitemporal data set in TM band intervals. All data (five total acquisitions) were acquired over a test site in Webster County, Iowa from June to October 1982. The use of TM data for determining development state is as accurate as with Landsat MSS and field plot data in MSS bands. The maximum deviation of 0.6 development stage for corn and 0.8 development stage for soybeans is well within the uncertainty with which a field can be estimated with procedures used by observers on the ground in 1982.

Professional identity in community mental health nursing: a thematic analysis.

Crawford, Paul; Brown, Brian; Majomi, Pam

2008-07-01

The study aimed to explore how community mental health nurses (CMHNs) UK perceived their working lives. This was subdivided into questions related to: How do nurses perceive their professional status in terms of public image compared with their understanding of their working lives? How does the relationship between professional aspirations and experiences of working life affect their feelings about their work and their self image? In a rapidly changing organizational context CMHNs face the challenge of achieving a coherent professional identity. An interview study was conducted and analyzed using semi-structured interviews and a thematic analysis to identify categories and themes in 34 CMHN's accounts of their working lives. The data were classified into four major themes: (i) The client focus: the public service identity of the profession; (ii) Not being a profession: skepticism, doubt and uncertainty; (iii) Growing out of the role: professional development as exit strategy; (iv) Waiting to be discovered: the search for recognition. The metaphor of nurses searching for recognition has demonstrated its usefulness as a means of illuminating the quest undertaken by CMHNs to establish the legitimacy of their work, and achieve acknowledgment and appreciation. This underlies the search for professional identity in community mental health nursing.

1988-01-01

Point-spread functions (PSF) comparisons were made between the Modular Optoelectronic Multispectral Scanner (MOMS-01), the LANDSAT Thematic Mapper (TM) and the SPOT-HRV instruments, principally near Lake Nakuru, Kenya. The results, expressed in terms of the width of the point spread functions at the 50 percent power points as determined from the in-scene analysis show that the TM has a PSF equal to or narrower than the MOMS-01 instrument (50 to 55 for the TM versus 50 to 68 for the MOMS). The SPOT estimates of the PSF range from 36 to 40. When the MOMS results are adjusted for differences in edge scanning as compared to the TM and SPOT, they are nearer 40 in the 575 to 625 nm band.

The absolute radiometric calibration of the NS001 Thematic Mapper Simulator reflective channels was examined based on laboratory tests and in-flight comparisons to ground measurements. The NS001 data are calibrated in-flight by reference to the NS001 internal integrating sphere source. This source's power supply or monitoring circuitry exhibited greater instability in-flight during 1988-1989 than in the laboratory. Extrapolating laboratory behavior to in-flight data resulted in 7-20 percent radiance errors relative to ground measurements and atmospheric modeling. Assuming constancy in the source's output between laboraotry and in-flight resulted in generally smaller errors. Upgrades to the source's power supply and monitoring circuitry in 1990 improved its in-flight stability, though in-flight ground reflectance based calibration tests have not yet been performed.

1984-01-01

An evaluation of Thematic Mapper Simulator (TMS) data for the geobotanical discrimination of rock types based on vegetative cover characteristics is addressed in this research. A methodology for accomplishing this evaluation utilizing univariate and multivariate techniques is presented. TMS data acquired with a Daedalus DEI-1260 multispectral scanner were integrated with vegetation and geologic information for subsequent statistical analyses, which included a chi-square test, an analysis of variance, stepwise discriminant analysis, and Duncan's multiple range test. Results indicate that ultramafic rock types are spectrally separable from nonultramafics based on vegetative cover through the use of statistical analyses.

Detection of soil erosion with Thematic Mapper (TM) satellite data within Pinyon-Juniper woodlands

NASA Technical Reports Server (NTRS)

Price, Kevin Paul

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.

A comparison between the first four thematic mapper reflective bands and other satellite sensor systems for vegetational monitoring

The first four Landsat-D thematic mapper sensors were evaluated and compared to the RBV and MSS sensors from Landsats-1, 2, and 3, Colvocoresses' proposed 'operational Landsat' three band system, and the French SPOT three band system using simulation/integration techniques and in situ collected spectral reflectance data. Sensors were evaluated by their ability to discriminate vegetation biomass, chlorophyll concentration, and leaf water content. The thematic mapper and SPOT bands were superior in a spectral resolution context to the other three sensor systems for vegetational applications. Significant improvements are expected for vegetational analyses from Landsat-D thematic mapper and SPOT imagery over MSS and RBV imagery.

Geographic information system (GIS) technology has become an important tool for scientific investigation, resource management, and environmental planning. A GIS is a computer-aided system capable of collecting, storing, analyzing, and displaying spatially referenced digital data. GIS technology is particularly useful when analyzing a wide variety of spatial data such as with remote sensing and spatial analysis. Remote sensing involves collecting remotely sensed data, such as satellite imagery, aerial photography, or radar images, and analyzing the data to gather information or investigate trends about the environment or the Earth's surface. Spatial analysis combines remotely sensed, thematic, statistical, quantitative, and geographical data through overlay, modeling, and other analytical techniques to investigate specific research questions. It is the combination of data formats and analysis techniques that has made GIS an essential tool in scientific investigations. This document presents information about the technical capabilities and project activities of the U.S. Geological Survey (USGS) Texas Water Science Center (TWSC) GIS Workgroup from 2002 through 2007.

Can thematic roles leave traces of their places?

PubMed

Chang, Franklin; Bock, Kathryn; Goldberg, Adele E

2003-11-01

An important question in the study of language production is the nature of the semantic information that speakers use to create syntactic structures. A common answer to this question assumes that thematic roles help to mediate the mapping from messages to syntax. However, research using structural priming has suggested that the construction of syntactic frames may be insensitive to variations in thematic roles within messages (Cognition 35 (1990) 1; Psychological Review 99 (1992) 150). Because these studies involved structural alternations whose syntax covaries with the order of thematic roles, it is difficult to assess any independent contribution that role information may make to the positioning of phrases. In this study, we primed the order of the roles without changing the syntactic structure of the sentences produced, and found that the order of the roles was influenced by the priming manipulation. This implies that thematic roles or the features that differentiate them are active within the mapping between messages and sentence structures.

The phenomenon of urban heat island was investigated by the use of LANDSAT Thematic Mapper data sets collected over the metropolitan area of Washington DC (U.S.). By combining the retrieved spectral albedos and temperatures, urban modification on radiation budgets of five surface categories were analyzed. The surface radiation budget imagery of the area show that urban heating is attributable to a large heat flux from the rapidly heating surfaces of asphalt, bare soil and short grass. In summer, symptoms of diurnal heating begin to appear by mid morning and can be about 10 degrees warmer than nearby woodlands in summer.

This research study examined Bud Goodall's online health narrative as a case study through the use of a thematic analysis to investigate the presence of communication privacy management (CPM) theory. Emergent themes of humor as a privacy management strategy, legitimization of co-owners, shifting privacy rules at end of life, and metaphors as privacy protection were used to recount Goodall's cancer experience on his personal blog, connecting to the components of CPM. The themes the authors analyzed represent the push-pull dialectical tension experienced to reveal and conceal information, conceptualization of private information, shared boundaries, and boundary linkages.

To explore the help-seeking pathway for lower bowel symptoms in men diagnosed with benign bowel diseases. Semi-structured interviews were conducted. The data were analyzed thematically using Andersen's Model of Patient Delay as the theoretical framework. The major delaying factors were attribution of symptoms to self-limiting conditions, failure to make time to visit a GP, low expectation of help from the GP, fear of cancer diagnosis and embarrassment. The major causes of delay in help-seeking were related to the participants, whereas factors associated with treatment delay were less prominent in diagnostic delay.

It is found that stratocumulus cloud number densities are represented by a power law. Cell horizontal aspect ratio has a tendency to increase at large cell sizes, and cells are bi-fractal in nature. Using LANDSAT Multispectral Scanner imagery for twelve selected stratocumulus scenes acquired during previous years, similar structural characteristics are obtained. Cloud field spatial organization also is analyzed. Nearest-neighbor spacings are fit with a number of functions, with Weibull and Gamma distributions providing the best fits. Poisson tests show that the spatial separations are not random. Second order statistics are used to examine clustering.

Background: The critical role that the board plays in governance of universities clarifies the necessity of evaluating its performance. This study was aimed to evaluate the performance of the boards of medical universities and provide solutions to enhance its performance. Methods: The first phase of present study was a qualitative research in which data were collected through face-to-face semi-structured interviews. Data were analyzed by thematic approach. The second phase was a mixed qualitative and quantitative study, with quantitative part in cross-sectional format and qualitative part in content analysis format. In the quantitative part, data were collected through Ministry of Health and Medical Education (MoHME). In the qualitative part, the content of 2,148 resolutions that were selected by using stratified sampling method were analyzed. Results: Participants believed that the boards had no acceptable performance for a long time.Results also indicated the increasing number of meetings and resolutions of the boards in these 21 years. The boards’ resolutions were mostly operational in domain and administrative in nature. The share of specific resolutions was more than the general ones. Conclusion: Given the current pace of change and development and the need to timely respond them, it is recommended to accelerate the slow pace of improvement process of the boards. It appears that more delegation and strengthening the position of the boards are the effective strategies to speed up this process. PMID:25337597

"Hopefully This Will All Make Sense at Some Point": Meaning and Performance in Illness Blogs.

PubMed

Heilferty, Catherine McGeehin

To analyze the narratives of illness blogs created by parents of children with cancer. The profound effects of the childhood cancer experience on family members and the turn to the Internet by parents for help in the process are gaining research attention. The qualitative study design involved secondary narrative analysis of 14 illness blogs: 9 by the parents of children with neuroblastoma and 5 by the parents of children with leukemia. Daily blog entries were analyzed as individual units of illness experience expression and in relation to one another to identify thematic and linguistic similarities. The initial analysis of these illness blogs resulted in identification of the quest for balance as a primary theme. Narratives in parents' childhood cancer illness blogs illustrated themes of performance. During this initial analysis, however, the author repeatedly asked, "Why are they writing this? And why publish this?" A second analysis of the data answered these questions of why parents blog about the experience. Narrative analysis resulted in the discovery of 6 main reasons that parents wrote and published the childhood cancer experience online: to report, explain, express, reflect, archive, and advocate. The analysis suggests that incorporation of parent writing may improve family--provider communication, enhance the family-health care professional relationship, enhance safety by preventing medical errors, improve reporting of clinical trial data such as adverse events, and improve satisfaction.

Background UniNet is an Internet-based thematic network for a virtual community of users (VCU). It supports a virtual multidisciplinary community for physicians, focused on the improvement of clinical practice. This is a study of the effects of a thematic network such as UniNet on primary care medicine in a rural area, specifically as a platform of communication between specialists at the hospital and doctors in the rural area. Methods In order to study the effects of a thematic network such as UniNet on primary care medicine in a rural area, we designed an interventional study that included a control group. The measurements included the number of patient displacements due to disease, number of patient hospital stays and the number of prescriptions of drugs of low therapeutic utility and generic drug prescriptions by doctors. These data were analysed and compared with those of the control center. Results Our study showed positive changes in medical practice, reflected in the improvement of the evaluated parameters in the rural health area where the interventional study was carried out, compared with the control area. We discuss the strengths and weaknesses of UniNet as a potential medium to improve the quality of medical care in rural areas. Conclusion The rural doctors had an effective, useful, user-friendly and cheap source of medical information that may have contributed to the improvement observed in the medical quality indices.

Despite conducting wide-ranging of pharmacotherapy for bipolar adolescents, many of them are showing a deficit in functioning with high relapse rate. The aim of the current study was to develop a manual and investigate the efficacy of group cognitive-behavioral therapy (G-CBT) for female bipolar adolescents. During the first qualitative phase of a mixed-methods study, a manual of G-CBT was developed. Then, 32 female bipolar adolescents aged 12-19 years old, receiving usual maintenance medications (UMM), were selected. Participants were randomized to the control (UMM) and intervention group (5, 2 h weekly sessions based on G-CBT manual with UMM). The parents in intervention group participated in three parallel sessions. All participants filled the following questionnaires before 1, 3, and 6 months after the initiation of the study: Young Mania Rating Scale, Children Depression Inventory and Global Assessment of Functioning. The results were analyzed using SPSS 21 software. The concurrent qualitative phase was analyzed through thematic analysis. The results showed no significant differences in all questionnaires' scores through intervention and follow-up sessions ( P > 0.05). However, using cutoff point of CDI, G-CBT was effective for intervention group (relapse rate: 25% vs. 44.4%). Two themes were extracted from the second qualitative phase: emotion recognition and emotion regulation, especially in anger control. The results showed that the addition of G-CBT to UMM leads to decrease in the depressive scores but has no effect on manic symptoms and relapse rate.

Evoked and event-related potentials in disorders of consciousness: A quantitative review.

PubMed

Kotchoubey, Boris

2017-09-01

Sixty-one publications about evoked and event-related potentials (EP and ERP, respectively) in patients with severe Disorders of Consciousness (DoC) were found and analyzed from a quantitative point of view. Most studies are strongly underpowered, resulting in very broad confidence intervals (CI). Results of such studies cannot be correctly interpreted, because, for example, CI>1 (in terms of Cohen's d) indicate that the real effect may be very strong, very weak, or even opposite to the reported effect. Furthermore, strong negative correlations were obtained between sample size and effect size, indicating a possible publication bias. These correlations characterized not only the total data set, but also each thematically selected subset. The minimal criteria of a strong study to EP/ERP in DoC are proposed: at least 25 patients in each patient group; as reliable diagnosis as possible; the complete report of all methodological details and all details of results (including negative results); and the use of appropriate methods of data analysis. Only three of the detected 60 studies (5%) satisfy these criteria. The limitations of the current approach are also discussed. Copyright © 2017 Elsevier Inc. All rights reserved.

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.

Validation of the Thematic Mapper radiometric and geometric correction algorithms

NASA Technical Reports Server (NTRS)

Fischel, D.

1984-01-01

The radiometric and geometric correction algorithms for Thematic Mapper are critical to subsequent successful information extraction. Earlier Landsat scanners, known as Multispectral Scanners, produce imagery which exhibits striping due to mismatching of detector gains and biases. Thematic Mapper exhibits the same phenomenon at three levels: detector-to-detector, scan-to-scan, and multiscan striping. The cause of these variations has been traced to variations in the dark current of the detectors. An alternative formulation has been tested and shown to be very satisfactory. Unfortunately, the Thematic Mapper detectors exhibit saturation effects suffered while viewing extensive cloud areas, and is not easily correctable. The geometric correction algorithm has been shown to be remarkably reliable. Only minor and modest improvements are indicated and shown to be effective.

As a part of the National Aeronautics and Space Administration Landsat D Image Data Quality Analysis Program, the Earth Resources Observation Systems Data Center (EDC) developed procedures to optimize the visual information content of Thematic Mapper data and evaluate the resulting photographic products by visual interpretation. A digital-to-analog transfer function was developed which would properly place the digital values on the most useable portion of a film response curve. Individual black-and-white transparencies generated using the resulting look-up tables were utilized in the production of color-composite images with varying band combinations. Four experienced photointerpreters ranked 2-cm-diameter (0. 75 inch) chips of selected image features of each band combination for ease of interpretability. A nonparametric rank-order test determined the significance of interpreter preference for the band combinations.

Several energy functions for synthesizing neural networks are tested on 2-D synthetic data and on Landsat-4 Thematic Mapper data. These new energy functions, designed specifically for minimizing misclassification error, in some cases yield significant improvements in classification accuracy over the standard least mean squares energy function. In addition to operating on networks with one output unit per class, a new energy function is tested for binary encoded outputs, which result in smaller network sizes. The Thematic Mapper data (four bands were used) is classified on a single pixel basis, to provide a starting benchmark against which further improvements will be measured. Improvements are underway to make use of both subpixel and superpixel (i.e. contextual or neighborhood) information in tile processing. For single pixel classification, the best neural network result is 78.7 percent, compared with 71.7 percent for a classical nearest neighbor classifier. The 78.7 percent result also improves on several earlier neural network results on this data.

Introduction While Human Resource Managers (HRM) and line managers could play a significant role in the prevention of job-related problems and in promotion of early job-continuation, it is not clear wether the chronically ill workers are recognized as a group. Unlike some other groups, distinguished by gender, age or ethnicity, those with chronic illness are less distinct and may not be included in diversity management programs. The aim of this research is to address theory and evidence in literature about the topic, as well as to inquire whether chronic illness of the employees is ‘visible’ in practice. Methods For desk research, we used a systematic search strategy involving medical, statistical, management, and social science databases (Web of Science, MedLine, Pub Med, Psych Info, etc.). Research results are based on case studies conducted with the managers and HRM of government and commercial organizations between March 2007 and October 2008 and between October 2008 and April 2009. These case studies were based on open interviews and focus group sessions (for human resource departments) which were consequently analyzed using thematical analysis. For group sessions, we used concept mapping to collect information from two groups of HRM professionals and managers. Secondary analysis included thematic and content analysis of ‘best practice’ organizations carried out by the Dutch organization Gatekeeper. Conclusions We have discovered that the chronically ill employees are largely invisible to HRM practitioners, line managers who do not always have the right instruments for implementation of the European or national frameworks. Most practitioners are unaware of the impact of chronic illness in their organizations and in employees work life. PMID:20383740

Introduction Health workforce shortages have driven the Australian and other Western governments to invest in engaging more health professional students in rural and remote placements. The aim of this qualitative study was to provide an understanding of the lived experiences of students undertaking placements in various nonmetropolitan locations across Australia. In addition to providing their suggestions to improve rural placements, the study provides insight into factors contributing to positive and negative experiences that influence students’ future rural practice intentions. Methods Responses to open-ended survey questions from 3,204 students from multiple health professions and universities were analyzed using two independent methods applied concurrently: manual thematic analysis and computerized content analysis using Leximancer software. Results The core concept identified from the thematic analysis was “ruralization of students’ horizons,” a construct representing the importance of preparing health professional students for practice in nonmetropolitan locations. Ruralization embodies three interrelated themes, “preparation and support,” “rural or remote health experience,” and “rural lifestyle and socialization,” each of which includes multiple subthemes. From the content analysis, factors that promoted students’ rural practice intentions were having a “positive” practice experience, interactions with “supportive staff,” and interactions with the “community” in general. It was apparent that “difficulties,” eg, with “accommodation,” “Internet” access, “transport,” and “financial” support, negatively impacted students’ placement experience and rural practice intentions. Conclusions The study findings have policy and practice implications for continuing to support students undertaking regional, rural, and remote placements and preparing them for future practice in nonmetropolitan locations. This study may, therefore, further inform ongoing strategies for improving rural placement experiences and enhancing rural health workforce recruitment, retention, and capacity building.

Using community-based participatory research, the Health Protection Model was used to understand the cultural experiences, attitudes, knowledge and behaviors surrounding caries etiology, its prevention and barriers to accessing oral health care for children of Latino parents residing in Central Indiana. A community reference group (CBPR) was established and bi-lingual community research associates were used to conduct focus groups comprised of Latino caregivers. Transcripts were analyzed for thematic content using inductive thematic analysis. Results indicated significant gaps in parental knowledge regarding caries etiology and prevention, with cultural underlays. Most parents believed the etiology of caries was related to the child's ingestion of certain foods containing high amounts of carbohydrates. Fewer parents believed either genetics/biological inheritance or bacteria was the primary causative factor. Fatalism negatively impacted preventive practices, and a clear separation existed concerning the perceived responsibilities of mothers and fathers to provide for the oral needs of their children. Females were more likely to report they were primarily responsible for brushing their children's teeth, overseeing the child's diet and seeking dental care for the child. Fathers believed they were primarily responsible for providing the means to pay for professional care. Perceived barriers to care were related to finances and communication difficulties, especially communicating with providers and completing insurance forms. The main study implication is the demonstration of how the CBPR model provided enhanced understanding of Latino caregivers' experiences to inform improvements in oral prevention and treatment of their children. Current efforts continue to employ CBPR to implement programs to address the needs of this vulnerable population.

Engaging stakeholders from varied organizational levels is essential to successful healthcare quality improvement. However, engagement has been hard to achieve and to measure across diverse stakeholders. Further, current implementation science models provide little clarity about what engagement means, despite its importance. The aim of this study was to understand how stakeholders of healthcare improvement initiatives defined engagement. Participants (n = 86) in this qualitative thematic study were purposively sampled for individual interviews. Participants included leaders, core members, frontline clinicians, support personnel, and other stakeholders of Strategic Clinical Networks in Alberta Health Services, a Canadian provincial health system with over 108,000 employees. We used an iterative thematic approach to analyze participants' responses to the question, "How do you define engagement?" Regardless of their organizational role, participants defined engagement through three interrelated themes. First, engagement was active participation from willing and committed stakeholders, with levels that ranged from information sharing to full decision-making. Second, engagement centered on a shared decision-making process about meaningful change for everyone "around the table," those who are most impacted. Third, engagement was two-way interactions that began early in the change process, where exchanges were respectful and all stakeholders felt heard and understood. This study highlights the commonalities of how stakeholders in a large healthcare system defined engagement-a shared understanding and terminology-to guide and improve stakeholder engagement. Overall, engagement was an active and committed decision-making about a meaningful problem through respectful interactions and dialog where everyone's voice is considered. Our results may be used in conjunction with current implementation models to provide clarity about what engagement means and how to engage various stakeholders.

Background Cultural values and beliefs related to cancer and pain have been used to explain ethnic differences in cancer pain experience. Yet, very little is known about similarities and differences in cancer pain experience among different ethnic groups. Objectives To explore similarities and differences in cancer pain experience among four major ethnic groups in the United States. Methods A feminist approach by Hall and Stevens was used. This was a cross-sectional qualitative study among 22 White, 15 Hispanic, 11 African American, and 27 Asian cancer patients recruited through both Internet and community settings. Four ethnic-specific online forums were conducted for 6 months. Nine topics related to cancer pain experience were used to guide the online forums. The collected data were analyzed using thematic analysis involving line-by-line coding, categorization, and thematic extraction. Results All participants across ethnic groups reported “communication breakdowns” with their health care providers and experienced “changes in perspectives.” All of them reported that their cancer pain experience was “gendered experience.” White patients focused on how to control their pain and treatment selection process, while ethnic minority patients tried to control pain by minimizing and normalizing it. White patients sought out diverse strategies of pain management; ethnic minority patients tried to maintain normal lives and use natural modalities for pain management. Finally, the cancer pain experience of White patients was highly individualistic and independent, while that of ethnic minority patients was family-oriented. Discussion These findings suggest that nurses need to use culturally competent approaches to cancer pain management for different ethnic groups. Also, the findings suggest further in-depth cultural studies on the pain experience of multiethnic groups of cancer patients. PMID:19289929

The aim of the study was to explore renal nurses' experiences, strategies and challenges with regard to the patient education process in peritoneal dialysis. Patient education in peritoneal dialysis is essential to developing a successful home-based peritoneal dialysis program. In this area research is scarce and there is a particular lack of focus on the perspective of the renal nurse. Qualitative design formed by thematic qualitative text analysis. Five group interviews (n = 20) were used to explore the challenges peritoneal dialysis nurses face and the training strategies they use. The interviews were analyzed with thematic qualitative content analysis using deductive and inductive subcategory application. The findings revealed the education barriers perceived by nurses that patients may face. They also showed that using assessment tools is important in peritoneal dialysis patient education, as is developing strategies to promote patient self-management. There is a need for a deeper understanding of affective learning objectives, and existing teaching activities and materials should be revised to incorporate the patient's perspective. Patients usually begin having questions about peritoneal dialysis when they return home and are described as feeling overwhelmed. Adapting existing conditions is considered a major challenge for patients and nurses. The results provided useful insights into the best approaches to educating peritoneal dialysis patients and served to raise awareness of challenges experienced by renal nurses. Findings underline the need for nosogogy - an approach of teaching adults (andragogy) with a chronic disease. Flexibility and cooperation are competencies that renal nurses must possess. Still psychomotor skills dominate peritoneal dialysis patient training, there is a need of both a deeper understanding of affective learning objectives and the accurate use of (self-)assessment tools, particularly for health literacy. © 2016 John Wiley & Sons Ltd.

"We Would Still Find Things to Talk About": Assessment of Mentor Perspectives in a Systemic Lupus Erythematosus Intervention to Improve Disease Self-Management, Empowering SLE Patients.

Systemic Lupus Erythematosus (SLE) is a chronic autoimmune disorder with significant disparate impact on African American women. The current study sought to highlight how the Peer Approaches to Lupus Self-management (PALS) intervention worked bi-directionally wherein both women with SLE leading the disease self-management program (mentors), and those participants who served as mentees, were empowered toward greater disease self-efficacy. Data was captured for this study in two formats from the seven mentors participating in the pilot study: 1) mentor logs and 2) mentor interviews with the principle investigator. This information was then analyzed for themes relating to their experience within the study. We found that empowerment was facilitated by mentors taking their mentorship responsibilities seriously and seeking several avenues for collaboratively developing success with their mentees. Mentors reported that although challenges arose, their desire for success resulted in multiple approaches to be flexible and responsive to the needs of their mentees. Additionally, reciprocity was found to be a vital element of the program. Key thematic areas supported our ability to demonstrate the usefulness of a peer mentoring program for SLE disease self-management on evoking empowerment through reciprocal relationships among mentors and mentees within our study population. Furthermore the feedback from PALS participants yielded very rich and contextual information that can be used as a thematic guide for developing and refining evidence-based interventions that seek to incorporate empowerment into disease self-management efforts for women suffering from SLE.

Hydrological variability over seasonal and multi-annual timescales strongly shapes the ecological structure and functioning of floodplain ecosystems. The current IPCC climate scenario foresees an increase in the frequency of extreme events. This, in conjunction with other anthropogenic disturbances (e.g., river regulation or land-use changes) poses a serious threat to the natural functioning of these ecosystems. In this study we aimed to i) evaluate the long-term variability of the flooded area of the third largest floodplain lake in the Brazilian Pantanal using remote sensing techniques, and ii) analyze the possible factors influencing this variability. Changes in open-water and riparian floodplain-wetland vegetation areas were mapped by applying an ad hoc-developed remote-sensing method (including a newly developed normalized water index, NWI) to 221 Landsat-Thematic Mapper (TM)/Enhanced Thematic Mapper Plus (ETM+) images, acquired between 1984 and 2011. Added to the lake's natural swing between riparian floodplain-wetland vegetation expansion and retraction, our analyses revealed large interannual changes, grouped into three main periods within the studied time interval. Moreover, our results indicate that this floodplain-lake system is losing open-water area, paired with an increase in riparian floodplain-wetland vegetation. The system's long-term dynamics are not all climate related, but are the result of a combination of drivers. The start of the Manso dam's operation upstream of the studied system, and the subsequent river regulation because of the dam operation, coupled with climatic oscillation appear to be responsible for the observed changes. However, other factors which were not considered in this study might also be important in this process and contributing to the reduction of the system's resilience to droughts (e.g., land-use changes). This study illustrates the serious conservation risks that the Pantanal faces in the near future, given the current climate-change scenario and the accumulation of dam building projects in this region.

In recent years, Lean manufacturing principles have been applied to health care quality improvement efforts to improve wait times. In Ontario, an emergency department (ED) process improvement program based on Lean principles was introduced by the Ministry of Health and Long-Term Care as part of a strategy to reduce ED length of stay (LOS) and to improve patient flow. This article aims to describe the hospital-based teams' experiences during the ED process improvement program implementation and the teams' perceptions of the key factors that influenced the program's success or failure. A qualitative evaluation was conducted based on semistructured interviews with hospital implementation team members, such as team leads, medical leads, and executive sponsors, at 10 purposively selected hospitals in Ontario, Canada. Sites were selected based, in part, on their changes in median ED LOS following the implementation period. A thematic framework approach as used for interviews, and a standard thematic coding framework was developed. Twenty-four interviews were coded and analyzed. The results are organized according to participants' experience and are grouped into four themes that were identified as significantly affecting the implementation experience: local contextual factors, relationship between improvement team and support players, staff engagement, and success and sustainability. The results demonstrate the importance of the context of implementation, establishing strong relationships and communication strategies, and preparing for implementation and sustainability prior to the start of the project. Several key factors were identified as important to the success of the program, such as preparing for implementation, ensuring strong executive support, creation of implementation teams based on the tasks and outcomes of the initiative, and using multiple communication strategies throughout the implementation process. Explicit incorporation of these factors into the development and implementation of future similar interventions in health care settings could be useful. © 2015 by the Society for Academic Emergency Medicine.

The East Greenland Tertiary Igneous Province contains a variety of intrusive and extrusive rock types. The Skaergaard complex is the most well known of the intrusive centers. Landsat thematic mapping (TM) was used in conjunction with field spectrometer data to map these mafic intrusions. These intrusions are of interest as possible precious metal ore deposits. They are spectrally distinct from the surrounding Precambrian gneisses. However, subpixel contamination by snow, oxide surface coatings, lichen cover and severe topography limit the discrimination of lithologic units within the gabbro. Imagery of the Skaergaard and surrounding vicinity, and image processing and enhancement techniques are presented. Student theses and other publications resulting from this work are also listed.

Strategic planning with a focus on world-class university status is an option that cannot be avoided by universities today to survive and succeed in competition as a provider of higher education. The objective of this research is to obtain exploratory research results on the strategic plans of universities that are prepared to generate world-class university status. This research utilised exploratory qualitative research method and data was collected by in-depth interviews method. Interview transcripts were analyzed by using thematic content analysis through NVivo software analysis and manual systems. The main finding of interview shows that most interviewees agreed that UNIMA has been engaged in strategic planning. Contribution from faculties and schools are acknowledged and inform the planning process. However, a new model of strategic planning should be adopted by UNIMA due to the shift towards a “corporate university”. The finding results from documents, literature review and interview were the addition of world-class university characteristics and features to current strategic planning of UNIMA and how to upgrade by considering to use the characteristics and features towards world-class university.

Analyzing Red and Gray Stages of Bark Beetle Attack in the San Bernardino National Forest Using Remote Sensing

NASA Astrophysics Data System (ADS)

Morgan, Andy J.

The San Bernardino National Forest (SBNF) has experienced periods of high, concentrated bark beetle epidemics in the late 1990's and into the 2000's. This increased activity has caused huge amounts of forest loss, resulting from disease introduced by bark beetles. Using remote sensing techniques and Landsat Thematic Mapper 5 (TM5) imagery, the spread of bark beetle diseased trees is mapped over a period from 1998 to 2008. Acreage of two attack stages (red and gray) were calculated from a level sliced classification method developed on data training sites. In each image using Normalized Difference Vegetation Index (NDVI) is the driver of forest health classifications. The results of the analysis are classification maps for each year, red acreage estimated for each study year, and gray attack acreage estimated for each study year. Additionally, for the period of 2001-2004, acreage was compared to those reported by the USDA with a thirteen percent lower mortality total in comparison to USDA federal land and a thirty-two percent lower total mortality (federal and non-federal) land in the SBNF.

Background: Health professional education has been criticized for not integrating patient expertise into professional curricula to develop professional skills in patient empowerment. Objective: To develop and translate a new expert patient-centered model for teaching empowerment into professional education about routine chronic care management. Methods: Eight Finnish patients (known as expert patients), 31 students, and 11 lecturers from 4 European countries participated in a new pilot intensive educational module. Thirteen focus groups, artefacts, and an online student evaluation were analyzed using a thematic analysis and triangulated using a meta-matrix. Results: A patient-centered pedagogical model is presented, which describes 3 phases of empowerment: (1) preliminary work, (2) the elements of empowerment, and (3) the expected outcomes. These 3 phases were bound by 2 cross-cutting themes “time” and “enabling resources.” Conclusion: Patient expertise was embedded into the new module curriculum. Using an example of care planning, and Pentland and Feldman’s theory of routine organization, the results are translated into a patient-centered educational model for teaching empowerment to health profession students.

A 25-item survey instrument was developed and distributed to 132 doctor of pharmacy (PharmD) programs. Survey data were analyzed using Mann-Whitney U test or Kruskal-Wallis test. Thematic analysis of text-based comments was performed using the constant comparison method. Results. One hundred twelve programs responded for a response rate of 85%. Seventy-eight (70%) offered integrated basic and clinical science courses. The types of integration included: full integration with merging disciplinary contents (n=25), coordinated delivery of disciplinary contents (n=50), and standalone courses with integrated laboratory (n=3). Faculty perceptions of course integration were positive. Themes that emerged from text-based comments included positive learning experiences as well as the challenges, opportunities, and skepticism associated with course integration. Conclusion. The results suggest wide variations in the design and implementation of integrated courses among US pharmacy programs. Faculty training and buy-in play a significant role in successful implementation of curricular integration. PMID:28179715

Training and test data sets for CAM1S from NS-001 MSS data for two dates (geometrically adjusted to 30 meter resolution) were used to evaluate wavelength band. Two sets of tapes containing digitized HH and HV polarization data were obtained. Because the SAR data on the 9 track tapes contained no meaningful data, the 7 track tapes were copied onto 9 track tapes at LARS. The LARSYS programs were modified and a program was written to reformat the digitized SAR data into a LARSYS format. The radar imagery is being qualitatively interpreted. Results are to be used to identify possible cover types, to produce a classification map to aid in the numerical evaluation classification of radar data, and to develop an interpretation key for radar imagery. The four spatial resolution data sets were analyzed. A program was developed to reduce the spatial distortions resulting from variable viewing distance, and geometrically adjusted data sets were generated. A flowchart of steps taken to geometrically adjust a data set from the NS-001 scanner is presented.

2014-01-01

Objectives To identify and review existing empirical research about service-learning and medical education and then to develop a framework for infusing service-learning in Doctor of Medicine or Doctor of Osteopathic Medicine curricula. Methods We selected literature on service-learning and medical education. Articles were screened with a protocol for inclusion or exclusion at two separate stages. At stage one, articles were screened according to their titles, abstracts, and keywords. The second stage involved a full-text review. Finally, a thematic analysis using focused and selective coding was conducted. Results Eighteen studies were analyzed spanning the years 1998 to 2012. The results from our analysis informed the development of a four-stage service-learning framework: 1) planning and preparation, 2) action, 3) reflection and demonstration, and 4) assessment and celebration. Conclusions The presented service-learning framework can be used to develop curricula for the infusion of service-learning in medical school. Service-learning curricula in medical education have the potential to provide myriad benefits to faculty, students, community members, and university-community partnerships. PMID:25341224

Development of a Conceptual Etiological Model of Treatment Regimen Fatigue Among Patients Engaged in HIV Care: A Qualitative Study.

PubMed

Claborn, Kasey; Miller, Mary Beth; Meier, Ellen; Carbone, Sofia

Treatment regimen fatigue (TRF) is a decreased desire and motivation to maintain vigilance in adhering to treatment, and little is known about TRF in people living with HIV. We aimed to develop a conceptual framework of TRF. Five focus groups were conducted in 2014. Eligible participants were (a) HIV infected, (b) at least 18 years of age, (c) prescribed antiretroviral therapy, and (d) fluent in English. Data were analyzed using thematic analysis. Analyses revealed these themes: patient experiences of TRF; etiological factors at the systems, provider, and patient levels; strategies to manage TRF; consequences of TRF; and protective factors that prevent the occurrence of TRF. The results provided a conceptual framework for future investigations to build on in an effort to improve adherence and retention in HIV care. Study results indicate avenues for intervention at multiple levels (systems, provider, and patient) to reduce treatment burden and improve patient resources and capacity.

Information on future land-use and land-cover (LULC) change is needed to analyze the impact of LULC change on ecological processes. The U.S. Geological Survey has produced spatially explicit, thematically detailed LULC projections for the conterminous United States. Four qualitative and quantitative scenarios of LULC change were developed, with characteristics consistent with the Intergovernmental Panel on Climate Change (IPCC) Special Report on 5 Emission Scenarios (SRES). The four quantified scenarios (A1B, A2, B1, and B2) served as input to the Forecasting Scenarios of Land-use Change (FORE-SCE) model. Four spatially explicit datasets consistent with scenario storylines were produced for the conterminous United States, with annual LULC maps from 1992 through 2100. The future projections are characterized by a loss of natural land covers in most scenarios, with corresponding expansion of 10 anthropogenic land uses. Along with the loss of natural land covers, remaining natural land covers experience increased fragmentation under most scenarios, with only the B2 scenario remaining relatively stable in both proportion of remaining natural land covers and basic fragmentation measures. Forest stand age was also modeled. By 2100, scenarios and ecoregions with heavy forest cutting have relatively lower mean stand ages compared to those with less 15 forest cutting. Stand ages differ substantially between unprotected and protected forest lands, as well as between different forest classes. The modeled data were compared to the National Land Cover Database (NLCD) and other data sources to assess model characteristics. The consistent, spatially explicit, and thematically detailed LULC projections and the associated forest stand age data layers have been used to analyze LULC impacts on carbon and greenhouse gas fluxes, 20 biodiversity, climate and weather variability, hydrologic change, and other ecological processes.

An evaluation of the first four LANDSAT-D thematic mapper reflective sensors for monitoring vegetation: A comparison with other satellite sensor systems

Tucker, C. J.

1978-01-01

The first four LANDSAT-D thematic mapper sensors were evaluated and compared to: the return beam vidicon (RBV) and multispectral scanners (MSS) sensors from LANDSATS 1, 2, and 3; Colvocoresses' proposed 'operational LANDSAT' three band system; and the French SPOT three band system using simulation/intergration techniques and in situ collected spectral reflectance data. Sensors were evaluated by their ability to discriminate vegetation biomass, chlorophyll concentration, and leaf water content. The thematic mapper and SPOT bands were found to be superior in a spectral resolution context to the other three sensor systems for vegetational applications. Significant improvements are expected for most vegetational analyses from LANDSAT-D thematic mapper and SPOT imagery over MSS and RBV imagery.

The Conceptual Framework of Thematic Mapping in Case Conceptualization.

PubMed

Ridley, Charles R; Jeffrey, Christina E

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.

Grammatical Encoding and Learning in Agrammatic Aphasia: Evidence from Structural Priming

Cho-Reyes, Soojin; Mack, Jennifer E.; Thompson, Cynthia K.

2017-01-01

The present study addressed open questions about the nature of sentence production deficits in agrammatic aphasia. In two structural priming experiments, 13 aphasic and 13 age-matched control speakers repeated visually- and auditorily-presented prime sentences, and then used visually-presented word arrays to produce dative sentences. Experiment 1 examined whether agrammatic speakers form structural and thematic representations during sentence production, whereas Experiment 2 tested the lasting effects of structural priming in lags of two and four sentences. Results of Experiment 1 showed that, like unimpaired speakers, the aphasic speakers evinced intact structural priming effects, suggesting that they are able to generate such representations. Unimpaired speakers also evinced reliable thematic priming effects, whereas agrammatic speakers did so in some experimental conditions, suggesting that access to thematic representations may be intact. Results of Experiment 2 showed structural priming effects of comparable magnitude for aphasic and unimpaired speakers. In addition, both groups showed lasting structural priming effects in both lag conditions, consistent with implicit learning accounts. In both experiments, aphasic speakers with more severe language impairments exhibited larger priming effects, consistent with the “inverse preference” prediction of implicit learning accounts. The findings indicate that agrammatic speakers are sensitive to structural priming across levels of representation and that such effects are lasting, suggesting that structural priming may be beneficial for the treatment of sentence production deficits in agrammatism.

Procedures used in characterizing geometric error sources for a spaceborne imaging system are described using the LANDSAT D thematic mapper ground segment processing as the prototype. Software was tested through simulation and is undergoing tests with the operational hardware as part of the prelaunch system evaluation. Geometric accuracy specifications, geometric correction, and control point processing are discussed. Cross track and along track errors are tabulated for the thematic mapper, the spacecraft, and ground processing to show the temporal registration error budget in pixel (42.5 microrad) 90%.

Simple models for complex natural surfaces - A strategy for the hyperspectral era of remote sensing

NASA Technical Reports Server (NTRS)

Adams, John B.; Smith, Milton O.; Gillespie, Alan R.

1989-01-01

A two-step strategy for analyzing multispectral images is described. In the first step, the analyst decomposes the signal from each pixel (as expressed by the radiance or reflectance values in each channel) into components that are contributed by spectrally distinct materials on the ground, and those that are due to atmospheric effects, instrumental effects, and other factors, such as illumination. In the second step, the isolated signals from the materials on the ground are selectively edited, and recombined to form various unit maps that are interpretable within the framework of field units. The approach has been tested on multispectral images of a variety of natural land surfaces ranging from hyperarid deserts to tropical rain forests. Data were analyzed from Landsat MSS (multispectral scanner) and TM (Thematic Mapper), the airborne NS001 TM simulator, Viking Lander and Orbiter, AIS, and AVRIS (Airborne Visible and Infrared Imaging Spectrometer).

"Keep All Thee 'Til the End": Reclaiming the Lifeworld for Patients in the Hospice Setting.

St Christopher's Hospice, London, was founded to provide specialist care to the incurably ill. We studied the dimensions of difference that set St Christopher's Hospice apart from hospital care of the dying, focusing on physical space and social organization. Material from 1953 to 1980 from the Cicely Saunders Archive was analyzed qualitatively. Through thematic analysis, quotes were found and analyzed using open coding. Five themes were developed. Themes identified were home/homelike, community, consideration of others, link with outside world, and privacy. The hospice philosophy functioned as the catalyst for the development of the physical environment of St Christopher's Hospice. Taking Habermas' concept of lifeworld, it seems that, in contrast to acute care, the need for hospice to formulate their own lifeworld to support and fully engage patients was central. As lifeworlds are culture sensitive, this underlines the need for variation in design and organization of hospices around the world.

Most cancer patients desire information about care options at the end of life, including cardiopulmonary resuscitation (CPR). Communicating such care options can be challenging and is part of advance care planning (ACP). Our prior studies with video educational media produced data on patients' categoric preferences (yes/no/unsure) for CPR; however, the thematic underpinnings of these educated preferences in patients treated for advanced cancer aren't well known. Qualitative thematic content analysis of participants' responses in a randomized trial of an educational video (V) or narrative (N) about CPR in patients with advanced gastrointestinal cancers. Responses were independently coded and categorized for thematic content by two reviewers. Of 54 study participants, 26 total (41% of V arm, 56% of N arm) articulated questions, comments, or both. Reviewer analyses demonstrated thematic consensus and resulted in seven distinct themes listed in decreasing order of prevalence: (a) ACP should be started early; (b) educational information about CPR affirmed participants' existing beliefs/knowledge/values about advanced illness; (c) participants were apprehensive about ACP but wanted to discuss it; (d) gaps in knowledge about ACP emerged; (e) CPR information was helpful/acceptable; (f) physicians should be involved in ACP; and (g) medical questions about critical illness arose. Findings identified that while sometimes difficult to discuss, advance care planning is desired, deemed helpful, and ideally begun early by clinicians, and that video education is an appropriate and affirming initiator of discussions. These themes are incorporated into our ongoing research on cancer patient-specific values and education about care options. Copyright © 2015 John Wiley & Sons, Ltd.

Objectives To thematically synthesise primary qualitative studies that explore challenges and facilitators for health professionals providing primary healthcare for refugees and asylum seekers in high-income countries. Design Systematic review and qualitative thematic synthesis. Methods Searches of MEDLINE, EMBASE, PsycINFO, CINAHL and Web of Science. Search terms were combined for qualitative research, primary healthcare professionals, refugees and asylum seekers, and were supplemented by searches of reference lists and citations. Study selection was conducted by two researchers using prespecified selection criteria. Data extraction and quality assessment using the Critical Appraisal Skills Programme tool was conducted by the first author. A thematic synthesis was undertaken to develop descriptive themes and analytical constructs. Results Twenty-six articles reporting on 21 studies and involving 357 participants were included. Eleven descriptive themes were interpreted, embedded within three analytical constructs: healthcare encounter (trusting relationship, communication, cultural understanding, health and social conditions, time); healthcare system (training and guidance, professional support, connecting with other services, organisation, resources and capacity); asylum and resettlement. Challenges and facilitators were described within these themes. Conclusions A range of challenges and facilitators have been identified for health professionals providing primary healthcare for refugees and asylum seekers that are experienced in the dimensions of the healthcare encounter, the healthcare system and wider asylum and resettlement situation. Comprehensive understanding of these challenges and facilitators is important to shape policy, improve the quality of services and provide more equitable health services for this vulnerable group.

Objective: To analyze communication skills of pediatric postgraduate residents in clinical encounter by using video recordings. Methods: This qualitative exploratory research was conducted through video recording at The Children’s Hospital Lahore, Pakistan. Residents who had attended the mandatory communication skills workshop offered by CPSP were included. The video recording of clinical encounter was done by a trained audiovisual person while the resident was interacting with the patient in the clinical encounter. Data was analyzed by thematic analysis. Results: Initially on open coding 36 codes emerged and then through axial and selective coding these were condensed to 17 subthemes. Out of these four main themes emerged: (1) Courteous and polite attitude, (2) Marginal nonverbal communication skills, (3) Power game/Ignoring child participation and (4) Patient as medical object/Instrumental behaviour. All residents treated the patient as a medical object to reach a right diagnosis and ignored them as a human being. There was dominant role of doctors and marginal nonverbal communication skills were displayed by the residents in the form of lack of social touch, and appropriate eye contact due to documenting notes. A brief non-medical interaction for rapport building at the beginning of interaction was missing and there was lack of child involvement. Conclusion: Paediatric postgraduate residents were polite while communicating with parents and child but lacking in good nonverbal communication skills. Communication pattern in our study was mostly one-way showing doctor’s instrumental behaviour and ignoring the child participation. PMID:29492050

Human papillomavirus (HPV)-related morbidity and mortality remain a significant public health burden despite the availability of HPV vaccines for cancer prevention. We engaged clinicians and parents to identify barriers and opportunities related to adolescent HPV vaccination within a focused geographic region. This mixed-method study design used an interviewer-administered semi-structured interview with clinicians (n = 52) and a written self-administered survey with similar items completed by parents (n = 54). Items focused on experiences, opinions, and ideas about HPV vaccine utilization in the clinical setting, family, and patient perceptions about HPV vaccination and potential future efforts to increase vaccine utilization. Quantitative items were analyzed using descriptive statistics, while qualitative content was analyzed thematically. Suggested solutions for achieving higher rates of HPV vaccination noted by clinicians included public health education, the removal of stigma associated with vaccines, media endorsements, and targeting parents as the primary focus of educational messages. Parents expressed the need for more information about HPV-related disease, HPV vaccines, vaccine safety, sexual concerns, and countering misinformation on social media. Results from this mixed-method study affirm that educational campaigns targeting both health care professionals and parents represent a key facilitator for promoting HPV vaccination; disease burden and cancer prevention emerged as key themes for this messaging.

This study analyzed land use and land cover changes and their impact on land surface temperature using Landsat 5 Thematic Mapper and Landsat 8 Operational Land Imager and Thermal Infrared Sensor imagery of the Yellow River Delta. Six Landsat images comprising two time series were used to calculate the land surface temperature and correlated vegetation indices. The Yellow River Delta area has expanded substantially because of the deposited sediment carried from upstream reaches of the river. Between 1986 and 2015, approximately 35% of the land use area of the Yellow River Delta has been transformed into salterns and aquaculture ponds. Overall, land use conversion has occurred primarily from poorly utilized land into highly utilized land. To analyze the variation of land surface temperature, a mono-window algorithm was applied to retrieve the regional land surface temperature. The results showed bilinear correlation between land surface temperature and the vegetation indices (i.e., Normalized Difference Vegetation Index, Adjusted-Normalized Vegetation Index, Soil-Adjusted Vegetation Index, and Modified Soil-Adjusted Vegetation Index). Generally, values of the vegetation indices greater than the inflection point mean the land surface temperature and the vegetation indices are correlated negatively, and vice versa. Land surface temperature in coastal areas is affected considerably by local seawater temperature and weather conditions.

Mental Health Literacy Content for Children of Parents with a Mental Illness: Thematic Analysis of a Literature Review

Riebschleger, Joanne; Grové, Christine; Cavanaugh, Daniel

2017-01-01

Millions of children have a parent with a mental illness (COPMI). These children are at higher risk of acquiring behavioural, developmental and emotional difficulties. Most children, including COPMI, have low levels of mental health literacy (MHL), meaning they do not have accurate, non-stigmatized information. There is limited knowledge about what kind of MHL content should be delivered to children. The aim of this exploratory study is to identify the knowledge content needed for general population children and COPMI to increase their MHL. A second aim is to explore content for emerging children’s MHL scales. Researchers created and analyzed a literature review database. Thematic analysis yielded five main mental health knowledge themes for children: (1) attaining an overview of mental illness and recovery; (2) reducing mental health stigma; (3) building developmental resiliencies; (4) increasing help-seeking capacities; and (5) identifying risk factors for mental illness. COPMI appeared to need the same kind of MHL knowledge content, but with extra family-contextual content such as dealing with stigma experiences, managing stress, and communicating about parental mental illness. There is a need for MHL programs, validated scales, and research on what works for prevention and early intervention with COPMI children. PMID:29072587

Most maternal deaths are preventable with emergency obstetric care; therefore, ensuring access is essential. There is little focused information on emergency transport of pregnant women. The literature on emergency transport of pregnant women in low- and middle-income countries (LMICs) was systematically reviewed and synthesized to explore current practices, barriers, and facilitators for transport utilization. MEDLINE, EMBASE, BNI, Cochrane Library, CINAHL, African Index Medicus, ASSIA, QUALIDATA, RHL, and Science Citation Index (inception to April 2012) were searched without language restriction. Studies using qualitative methodology and reporting on emergency transportation in LMICs were included. Thematic framework and synthesis through examination and translation of common elements were used to analyze and synthesize the data. Twenty-nine articles were included. Eight major themes were identified: time for transport; transport options; geography; local support; autonomy; culture; finance; and ergonomics. Key issues were transport availability; transport speed; terrain; meteorology; support; dependence for decision making; cultural issues; cost; and lack of safe, comfortable positioning during transport. Themes should be appreciated within local contexts to illuminate barriers and facilitators. Potential solutions include motorcycle ambulance programs, collaboration with taxi services, community education, subsidies, and vehicle maintenance.

The objectives of this article are to (1) comprehensively catalog outcomes measured in trials of childhood vaccination communication interventions and (2) analyze patterns and trends in outcome selection. To achieve these objectives, we developed a Trial Outcomes Map for vaccination communication. We searched the Cochrane Central Register of Controlled Trials for trials of childhood vaccination communication interventions, extracting verbatim all outcome information from included trials. Through thematic grouping, we categorized outcomes based on conceptual similarities, forming a Trial Outcomes Map. We identified 112 relevant trials containing 209 outcomes. Thematic analysis revealed three overarching Outcome Categories: consumer-, vaccination-, and health system-related outcomes. These categories contain 21 Outcome Types (eg, "knowledge," "cost"), measured using 66 different Outcome Variables. Vaccination outcomes were measured most frequently and health system-related outcomes least frequently. Consumer outcomes are increasingly measured in more recent trials. The number of measures used for the same outcomes complicates data synthesis and interpretation. Despite recent trends toward including consumer outcomes, intermediate outcome measurement is lacking, hampering understanding of how and why vaccination communication interventions do or do not work. This Map may improve outcome consistency in future trials and will contribute to a forthcoming core outcome set. Copyright © 2016 The Authors. Published by Elsevier Inc. All rights reserved.

The Northeastern/Central Pennsylvania Interprofessional Education Coalition (NECPA IPEC) is a coalition of faculty from multiple smaller academic institutions with a mission to promote interprofessional education. An interprofessional learning program was organized, which involved 676 learners from 10 different institutions representing 16 unique professions, and took place at seven different institutions simultaneously. The program was a 3-hour long summit which focused on the management of a patient with ischemic stroke. A questionnaire consisting of the Interprofessional Education Perception Scale (IEPS) questionnaire (pre-post summit), Likert-type questions, and open comment questions explored the learners' perceptions of the session and their attitudes toward interprofessional learning. Responses were analyzed using descriptive statistics and statistical tests for difference and qualitative thematic coding. The attitude of learners toward interprofessional education (as measured by the IEPS) was quite high even prior to the summit, so there were no significant changes after the summit. However, a high percentage of learners and facilitators agreed that the summit met its objective and was effective. In addition, the thematic analysis of the open-ended questions confirmed that students learned from the experience with a sense of the core competencies of interprofessional education and practice. A collaborative approach to delivering interprofessional learning is time and work intensive but beneficial to learners.

Goal oriented cognitive rehabilitation is a promising intervention for individuals diagnosed with mild cognitive impairment (MCI) or dementia due to Alzheimer Disease (AD). Videoconferencing delivered cognitive rehabilitation is a potential avenue for increasing accessibility for rural patients and their families. First, we were concerned with the accessibility of the treatment for individuals in rural and remote areas. Second, client-centered goal setting was explored by asking this sample about their goals for cognitive rehabilitation. We mailed questions to all active patients with diagnoses of MCI or dementia due to AD of a rural memory clinic and compare features of the responders versus the non-responders. We asked about interest in videoconferencing delivered treatment and about goals for cognitive rehabilitation, which were thematically analyzed. The responders (N = 25) were similar to non-responders in severity, depression, and caregiver burden. Of the responders, 80% were interested in videoconferencing developed treatment. A thematic analysis coded 95% of responses as amenable to cognitive rehabilitation. Participants' goals were focused on memory, household activities, other cognitive domains, recreation, and higher order tasks. This work informs the development of both in-person and videoconferencing delivered cognitive rehabilitation for individuals diagnosed with MCI or dementia.

This study aimed to identify procedural elements of Japanese acupuncture, describe these elements in detail, and explain them in terms of the key thematic category of treatment principles. Between August 2012 and December 2016, ethnographic fieldwork was conducted in Japan. In total, 38 participants were recruited by chain referral and emergent sampling. Data was collected through participant observation, interviews, and by analyzing documents. A total of 22 participants agreed to clinical observation; 221 treatments were observed with 172 patients. Seventeen consented to formal interviews and 28 to informal interviews. Thematic analysis was used to critically evaluate data. One especially interesting theme was interpreted from the data: a variety of contact tools were applied in treatment and these were manipulated by adjusting elements of form, speed, repetition, and pressure. Tapping, holding, pressing/pushing, and stroking were the most important ways contact tools were used on patients. Contact tools are noninvasive, painless, can be applied in almost any environment, and may be easily accepted by patients worldwide. Contact tool theory and practice may be successfully integrated into acupuncture curricula outside of Japan, used to inform clinical trials, and contribute to an expanded repertoire of methods for practitioners to benefit individual patients in international contexts.

Sentence comprehension is a complex process. Besides identifying the meaning of each word and processing the syntactic structure of a sentence, it requires the computation of thematic information, that is, information about who did what to whom. The present fMRI study investigated the neural basis for thematic reanalysis (reanalysis of the thematic roles initially assigned to noun phrases in a sentence) and its interplay with syntactic reanalysis (reanalysis of the underlying syntactic structure originally constructed for a sentence). Thematic reanalysis recruited a network consisting of Broca's area, that is, the left pars triangularis (LPT), and the left posterior superior temporal gyrus, whereas only LPT showed greater sensitivity to syntactic reanalysis. These data provide direct evidence for a functional neuroanatomical basis for two linguistically motivated reanalysis processes during sentence comprehension. Copyright © 2010 Wiley-Liss, Inc.

What does a well-designed thematic workshop look like? Walking into a presentation at a convention center or at a NASA center, one might see formal and informal educators receiving space science content from knowledgeable science experts, actively participating in topic-related activities, questioning, collaborating, and investigating, connecting topics and content to their education needs, and having fun. But what is really going on, and what did it take to get to this point-the point of delivery. This is an opportunity to share experience and knowledge pertaining to designing and conducting space science thematic workshops and trainings. It is an attempt to describe the thematic approach to space science education that has been demonstrated in Solar System Exploration Education Forum workshops over many years and to articulate the best practices pertain-ing to designing and presenting those workshops.

Temporal Dynamics of Activation of Thematic and Functional Knowledge During Conceptual Processing of Manipulable Artifacts

2012-01-01

The current research aimed at specifying the activation time course of different types of semantic information during object conceptual processing and the effect of context on this time course. We distinguished between thematic and functional knowledge and the specificity of functional similarity. Two experiments were conducted with healthy older adults using eye tracking in a word-to-picture matching task. The time course of gaze fixations was used to assess activation of distractor objects during the identification of manipulable artifact targets (e.g., broom). Distractors were (a) thematically related (e.g., dustpan), (b) related by a specific function (e.g., vacuum cleaner), or (c) related by a general function (e.g., sponge). Growth curve analyses were used to assess competition effects when target words were presented in isolation (Experiment 1) and embedded in contextual sentences of different generality levels (Experiment 2). In the absence of context, there was earlier and shorter lasting activation of thematically related as compared to functionally related objects. The time course difference was more pronounced for general functions than specific functions. When contexts were provided, functional similarities that were congruent with context generality level increased in salience with earlier activation of those objects. Context had little impact on thematic activation time course. These data demonstrate that processing a single manipulable artifact concept implicitly activates thematic and functional knowledge with different time courses and that context speeds activation of context-congruent functional similarity.

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.

Analyze the role of the nurse at the end of the life of a critically ill patient. Bibliographic review from a search of the health science databases such as PubMed, CINAHL, Cuiden, Scopus, Cochrane, as well as specialized platforms, general and thematic browsers. The limits were language (English or Spanish) and publication date (2005-2015). 180 articles met the inclusion criteria, and 16 of them were selected for analysis. The main results were grouped into three categories of analysis: direct patient care, family-focussed care and the nurse's role within the team. the described roles place the nurse as a key element in humanising death in the ICU and so nurses can and must lead change, playing an active role in creating strategies that really promote the integration of a palliative care approach in ICU.

Outsourcing labor is linked to negative impacts on occupational health and safety (OHS). In British Columbia, Canada, provincial health care service providers outsource support services such as cleaners and food service workers (CFSWs) to external contractors. This study investigates the impact of outsourcing on the occupational health safety of hospital CFSWs through a mixed methods approach. Worker's compensation data for hospital CFSWs were analyzed by negative binomial and multiple linear regressions supplemented by iterative thematic analysis of telephone interviews of the same job groups. Non-significant decreases in injury rates and days lost per injury were observed in outsourced CFSWs post outsourcing. Significant decreases (P < 0.05) were observed in average costs per injury for cleaners post outsourcing. Outsourced workers interviewed implied instances of underreporting workplace injuries. This mixed methods study describes the impact of outsourcing on OHS of healthcare workers in British Columbia. Results will be helpful for policy-makers and workplace regulators to assess program effectiveness for outsourced workers.

With the image data (SPOT), soil utilization map (1:50000) and other related materials of Harbin, and under the support of GIS, RS and GPS techniques, this paper obtained the landscape pattern of Harbin suburb and the Digital Elevation Model (DEM) of Harbin. Indices including mean patch area, landscape dominance, mean slope, mean altitude, and fragmentation degree were selected and synthetically analyzed, with the ecological landscape planning made by DEM model. The results showed that 3S techniques could help to decide typical landscape types. The landscape type database was established, and the landscape type thematic map was generated, with land use status and landscape distribution, physiognomy, and land use types combined. The ecological landscape planning was described in large scale with the image data and DEM combined, and the landscape structure of Harbin suburb was reflected directly with the ecological landscape planning and DEM combined, which improved the ecological function in this region, and provided scientific bases to the healthy development in urban-rural integration area.

2015-06-01

The close relationship between local residents and the Rio Doce and the river's recurrent flooding lead to continuous exposure of the population to waterborne diseases. Given the epidemiological importance of such diseases in the region, this study analyzes the association between risk perception of contamination and river water use, as well as the heuristic mechanisms used by individuals to shape their personal perception of risk. Regression models coupled with thematic network analysis were applied to primary data from 352 households in 2012. The data are representative of urban residents of Tumiritinga, Minas Gerais State, Brazil. The results show that while 92.6% of respondents perceived high risk of waterborne diseases, only 11.4% reported not making direct use of the river. This apparent paradox is explained by the lack of information on transmission mechanisms, underestimating the perception of contamination. Public campaigns to promote preventive behavior should stress how waterborne diseases are transmitted, using simple examples to reach a wider local audience.

An overview of infusing service-learning in medical education.

Stewart, Trae; Wubbena, Zane

2014-08-04

To identify and review existing empirical research about service-learning and medical education and then to develop a framework for infusing service-learning in Doctor of Medicine or Doctor of Osteopathic Medicine curricula. We selected literature on service-learning and medical education. Articles were screened with a protocol for inclusion or exclusion at two separate stages. At stage one, articles were screened according to their titles, abstracts, and keywords. The second stage involved a full-text review. Finally, a thematic analysis using focused and selective coding was conducted. Eighteen studies were analyzed spanning the years 1998 to 2012. The results from our analysis informed the development of a four-stage service-learning framework: 1) planning and preparation, 2) action, 3) reflection and demonstration, and 4) assessment and celebration. The presented service-learning framework can be used to develop curricula for the infusion of service-learning in medical school. Service-learning curricula in medical education have the potential to provide myriad benefits to faculty, students, community members, and university-community partnerships.

2016-06-01

Recreation is an essential part of life that provides enriching experiences that may define one's life course similar to careers or other interests. An understanding of the role of volunteers in active community-based recreational programs can help to generate ways to enhance participation and contribute to additional communication opportunities with people who have complex communication needs. Nine volunteers from two adaptive ski programs and one therapeutic horseback-riding program in the Northeast region of the United States participated in semi-structured interviews. Audio-recordings were transcribed and analyzed and resulted in five thematic areas: (a) benefits, (b) why individuals volunteer, (c) barriers, (d) successful program supports, and (e) who are the riders and skiers using AAC. The findings provided insight to support the notion that active community-based recreational activities foster an environment for communication, meaningful engagement, and social relationships between volunteers and people with complex communication needs.

2018-01-01

In recent years, understanding prejudice and discrimination toward minorities has developed to include the investigation of microaggressions. Microaggressions are brief and commonplace verbal, behavioral, or environmental indignities. They are intentional or unintentional and communicate hostile, derogatory, or negative slights toward racial and sexual minorities. The purpose of this phenomenological study is to chronicle the prevalence and type of microaggressions experienced among a sample of 18 highly educated and racially diverse sexual minorities, 24-65 years of age. The impact of microaggressions on physical and psychological health is central to our investigation. Thematic data analysis was used to analyze 14 interviews and one focus group, which resulted in the following themes of microaggressions: (a) discomfort/disapproval with LGBT experience, (b) assumption of universal experience, (c) traditional gender role stereotyping, (d) denial of personal privacy, (e) exoticization, (f) ascription of intelligence, (g) policing bodies, and (h) assumption of criminality. Research findings may have implications for the development of interventions that can serve clinicians in their therapeutic work with microaggressed sexual minorities across racial diversity.

Palacios-Ceña, Domingo; Martínez-Piedrola, Rosa María; Pérez-de-Heredia, Marta; Huertas-Hoyas, Elisabet; Carrasco-Garrido, Pilar; Fernández-de-Las-Peñas, Cesar

In nursing homes, a number of barriers to the expression of sexuality exist, such as the lack of privacy, certain attitudes on behalf of the staff and the family, the lack of a sexual partner, and physical limitations. The aim of this study was to describe the lived experience of sexuality in elderly Spanish women residing in nursing homes. A qualitative phenomenological approach was followed. Data were collected over an 18-month period between 2013 and 2015. Purposeful sampling was conducted with Spanish residents in nursing homes in Madrid. Data were collected using unstructured and semi-structured interviews. The data were analyzed using thematic analysis. Twenty female residents participated. Three main themes emerged from the data: a) expressing sexuality, b) sexuality as a duty and c) respecting vows. Female residents reported key elements influencing how they manage their sexuality in Nursing Homes. These results serve to improve our understanding regarding the expression of sexuality in older female nursing home residents. Copyright © 2016 Elsevier Inc. All rights reserved.

Mulligan, Kerry; Calder, Allyson; Mulligan, Hilda

2018-04-01

The built environment can facilitate or impede an individual's ability to participate in society. This is particularly so for people with disability. Architects are well placed to be advocates for design that enhances societal equality. This qualitative study explored architectural design students' perceptions of inclusive design, their reflections resulting from an experiential learning module and the subsequent influence of these on their design practice. Twenty four architectural design students participated in focus groups or individual interviews. Data were analyzed thematically. Three themes were evident: 1) Inclusive design was perceived as challenging, 2) Appreciation for the opportunity to learn about the perspectives of people with disabilities, and 3) Change of attitude toward inclusive design. Experiential learning had fostered reflection, changes in attitude and the realization that inclusive design, should begin at the start of the design process. For equitable access for all people to become reality, experiential learning, coupled with positive examples of inclusive design should be embedded in architectural education.

The study aimed to analyze the process of becoming a caregiver of elderly patients with cancer, in chemotherapy, in the home context. This is an exploratory study with theoretical and methodological orientation of interpretative anthropology and ethnographic case study. Data were collected from January to September 2009, with four caregivers through semi-structured interviews, observation and consultation records. With data analysis were built four units of meaning. In this paper 'we are focusing the thematic unity "The ressignification of caregiver's life", composed by positive aspects of caregiving activities and of helping to overcome difficulties, such as union, solidarity, opportunity for reapproximation. The difficulties were more evident, especially being unprepared to care at home, which led to changes in the caregiver's familiar and social relationships, resulting in impairment of physical, emotional and social aspects. The nurse, as an agent of care, must provide adequate qualification to the caregivers, helping them in coping with the disease and improving the patient-caregiver-service relationship.

Background Under-recruitment to randomised controlled trials (RCTs) is often problematic and there may be particular difficulties in recruiting patients with severe mental illness. Aim To evaluate reasons for under-recruitment in an RCT of patients with severe mental illness Methods Qualitative study during the recruitment phase of an RCT of supported employment. Trial staff and recruiting clinicians were interviewed. Data were analyzed thematically using constant comparative techniques. Results Recruitment rates were low. Five main reasons for recruitment difficulties were found. These included: (i) misconceptions about trials, (ii) lack of equipoise, (iii) misunderstanding of the trial arms, (iv) variable interpretations of eligibility criteria, (v) paternalism. Conclusion Reasons for recruitment difficulties in trials involving patients with severe mental illness include issues that occur in trials in general, but others are more specific to these patients. Clinician and patient involvement in the study design may improve recruitment in future similar trials. PMID:18718555

Justice, C.; Fusco, L.; Mehl, W.

1985-01-01

The NASA raw (BT) product, the radiometrically corrected (AT) product, and the radiometrically and geometrically corrected (PT) product of a TM scene were analyzed examine the frequency distribution of the digital data; the statistical correlation between the bands; and the variability between the detectors within a band. The analyses were performed on a series of image subsets from the full scence. Results are presented from one 1024 c 1024 pixel subset of Realfoot Lake, Tennessee which displayed a representative range of ground conditions and cover types occurring within the full frame image. From this cursory examination of one of the first seven channel TM data sets, it would appear that the radiometric performance of the system is most satisfactory and largely meets pre-launch specifications. Problems were noted with Band 5 Detector 3 and Band 2 Detector 4. Differences were observed between forward and reverse scan detector responses both for the BT and AT products. No systematic variations were observed between odd and even detectors.

2013-01-01

Research on basic human motives (achievement, affiliation, and power) encoded at the emotional level recently returned to the forefront of scientific research. To date, there are only a few studies on the pattern of implicit motives of substance users, so the present study examined opiate users participating in methadone maintenance treatment (N = 80) along these dimensions, comparing them to 40 non-substance users. Participants were asked to create stories on the basis of the pictures of the Thematic Apperception Test. The stories were analyzed using the content analysis method of David Winter (1991). Like other substance user groups, opiate-dependent persons used less achievement and more affiliation notions in creating stories, while there was no significant difference between the two groups concerning power notions. The results proved to be independent of the presence of anxiety and depression symptoms, despite substance users reporting higher levels of these, and suggest that motivational factors are worth considering in treatment planning.

Objective To explore maternal beliefs about TV viewing and related parenting practices in low-income Mexican-origin mothers of preschoolers. Methods Semi-structured interviews were conducted with 21 low-income Mexican-origin mothers of preschoolers. Interviews were audio recorded and analyzed using a theoretically based thematic analytic approach. Results Mothers described strong beliefs about the positive and negative impact of television content. Mothers emphasized the educational value of specific programming. Content restrictions were common. Time restrictions were not clearly defined; however, many mothers preferred short versus long episodes of viewing. Mothers spoke positively about family viewing and the role of TV viewing in enabling mothers to accomplish household tasks. Discussion These findings have implications for intervening in this population. Interventionists should consider the value mothers place on the educational role of TV viewing, the direct benefit to mothers of viewing time, the lack of clear time limits, and the common practice of family co-viewing.

To explore the perceived effects of an aerobic exercise program delivered in specialist schools for young people with cerebral palsy with high support needs. In-depth interviews were completed with 8 students with cerebral palsy, 10 parents, 8 teachers and 7 physiotherapists. Interviews were audio-recorded, transcribed verbatim and independently coded by two researchers. Data were analyzed using thematic analysis. Two themes emerged: one about program impact and the second about influential design features. Exercise was perceived as important, and participants indicated that the program had resulted in positive physical (e.g., improved ease of mobility, fitness and stamina) and psychosocial (e.g., happiness, social experience, challenge) impacts. The school setting, program staff and student attitudes were key features of the program. These data converge with those from a randomized controlled trial and attribute physical and psychosocial benefits to a specialist school-based exercise program for young people with cerebral palsy.

2014-01-01

Objectives. We explored qualitatively US servicewomen’s experiences with and perceptions of military sexual trauma (MST), reporting, and related services. Methods. From May 2011 to January 2012, we conducted 22 telephone interviews with US servicewomen deployed overseas between 2002 and 2011. We analyzed data thematically with modified grounded theory methods. Results. Factors identified as contributing to MST included deployment dynamics, military culture, and lack of consequences for perpetrators. Participants attributed low MST reporting to negative reactions and blame from peers and supervisors, concerns about confidentiality, and stigma. Unit cohesion was cited as both a facilitator and a barrier to reporting. Availability and awareness of MST services during deployment varied. Barriers to care seeking were similar to reporting barriers and included confidentiality concerns and stigma. We identified several avenues to address MST, including strengthening consequences for perpetrators. Conclusions. We identified barriers to MST reporting and services. Better understanding of these issues will allow policymakers to improve MST prevention and services. PMID:24328617

The Symbolic Nature of Trust in Heterosexual Adolescent Romantic Relationships.

2017-08-01

Trust contributes to young people's capacity for sustaining current and future successful relationships. To date, research has yet to examine the meaning of trust in early dating relationships and reasons for its deterioration. The present study focused on video-recorded conversations about trust between 34 heterosexual adolescent couples in dating relationships living in the U.S. Transcripts from these conversations were qualitatively analyzed using thematic analysis to identify adolescents' meanings of trust and reasons they provided for a lack of trust in their romantic partners. All 34 couples identified concerns specifically related to infidelity. Six major themes for not trusting romantic partners emerged. Results suggested that the lack of trust in romantic relationships might stem from several areas that are directly and indirectly related to the current relationship, including low self-esteem, the experience of betrayal in past romantic relationships, partners' extradyadic behaviors, and gossip among peers. Importantly, peers can play a defining role in influencing young people's perceptions of their romantic partners and developing or sustaining trust in their romantic relationships.

In this paper we explore themes that cut across how 24-77 year old African American men define manhood and health. Utilizing a thematic approach, we analyzed data from nine focus groups (N=73). We found that manhood and health were relational constructs that are interrelated in men's minds and experiences. Manhood and health were defined by the characteristics men embody, the behaviors men engage in and the goals and values men had to positively influence their families and communities. Thus, manhood and health are interdependent constructs and their interrelationship should be considered in efforts to promote African American men's health. PMID:26291189

We explored knowledge, attitudes, and practices associated with the menopause transition particular to women in the multi-ethnic cultural context of Singapore. Fifty-eight Chinese, Malay, and Indian Singaporean women participated in interviews that were audiorecorded, transcribed verbatim, and analyzed using thematic analysis. Women from all three ethnicities described an attitude of acceptance surrounding menopause and the changes associated with it. While they thought it was important to be informed, they did not seek out information about menopause and did not view health professionals as useful sources of information. Management practices were diverse and rarely involved accessing health professionals.

Migration has implications for women's sexual and reproductive health and rights. Our purpose with this study was to explore unmarried migrant women's perceptions of relationships and sexuality in the context of Sri Lankan Free Trade Zones. Sixteen semi-structured qualitative interviews were analyzed using thematic analysis. We found that the women's perceptions were influenced by gendered hegemonic notions of respectability and virginity. Complex gender relations both worked in favor of and against women's sexual and reproductive health and rights. Programs for improvement of migrant women's health should be informed by contextualized analysis of gender relations with its various dimensions and levels.

2012-01-01

Social neuroscience and its potential implications create an interesting case study for examining human research ethics policies on the topic of public communication of research. We reviewed mainstream national and international human research ethics guidelines and policies on issues of public communication of research. Our analysis relied on five thematic nets to capture the interactions between research and the public: public understanding, knowledge translation, public participation, social outcomes, and dual use. Coverage of these topics is sparse and inconsistent in mainstream policies and guidelines. We identify three options to address these gaps and analyze their strengths and weaknesses.

Card, D. H.; Wrigley, R. C.; Mertz, F. C.; Hall, J. R.

1984-01-01

The design of the Thematic Mapper (TM) multispectral radiometer makes it susceptible to band-to-band misregistration. To estimate band-to-band misregistration a block correlation method is employed. This method is chosen over other possible techniques (band differencing and flickering) because quantitative results are produced. The method correlates rectangular blocks of pixels from one band against blocks centered on identical pixels from a second band. The block pairs are shifted in pixel increments both vertically and horizontally with respect to each other and the correlation coefficient for each shift position is computed. The displacement corresponding to the maximum correlation is taken as the best estimate of registration error for each block pair. Subpixel shifts are estimated by a bi-quadratic interpolation of the correlation values surrounding the maximum correlation. To obtain statistical summaries for each band combination post processing of the block correlation results performed. The method results in estimates of registration error that are consistent with expectations.

Objective: to identify the opinion of parents or guardians of adolescents diagnosed with Attention Deficit Hyperactivity Disorder (ADHD) about their children's exposure as perpetrators or victims of violence situations in family life or outside. Method: qualitative study with use of thematic oral history. Nine parents of 07 adolescents with ADHD participated. Data were collected from April to September of 2013 using thematic interview. The interviews were recorded at scheduled times at the participants' home, with an average duration of 30 minutes. The findings were submitted to inductive thematic analysis. Results: data analysis allowed the identification of the occurrence of "Conflicts in family life" and "Conflicts in the context of school and community". Parents reported the involvement of their children as victims, perpetrators and witnesses of physical and psychological violence, and the difficulty of them and the school to understand and handle these situations. Conclusion: violence occurs in ADHD adolescents' interpersonal relationships. Communication between health professionals, school and families is precarious. Through the systematization of nursing care, nurses can plan strategies that articulate support networks and interpersonal relationships of adolescents with the disorder (family and school).

Color composite TM film products which include TM5, TM4, and a visible band (TM1, TM2, or TM3) are superior to composites which exclude TM4 for discriminating most forest and agricultural cover types and estimating area proportions for inventory and sampling purposes. Clustering a subset of TM data results in a spectral class map which groups diverse forest cover types into spectrally and ecologically similar areas suitable for use as a stratification base in traditional forest inventory practices. Analysis of simulated Thematic Mapper data indicate that the location and number of TM spectral bands are suitable for detecting differences in major soil properties and characterizing soil spectral curve form and magnitude.

A number of studies have explored the role of associative/event-based (thematic) and categorical (taxonomic) relations in the organization of object representations. Recent evidence suggests that thematic information may be particularly important in determining relationships between manipulable artifacts. However, although sensorimotor information is on many accounts an important component of manipulable artifact representations, little is known about the role that action may play during the processing of semantic relationships (particularly thematic relationships) between multiple objects. In this study, we assessed healthy and left hemisphere stroke participants to explore three questions relevant to object relationship processing. First, we assessed whether participants tended to favor thematic relations including action (Th+A, e.g., wine bottle—corkscrew), thematic relationships without action (Th-A, e.g., wine bottle—cheese), or taxonomic relationships (Tax, e.g., wine bottle—water bottle) when choosing between them in an association judgment task with manipulable artifacts. Second, we assessed whether the underlying constructs of event relatedness, action relatedness, and categorical relatedness determined the choices that participants made. Third, we assessed the hypothesis that degraded action knowledge and/or damage to temporo-parietal cortex, a region of the brain associated with the representation of action knowledge, would reduce the influence of action on the choice task. Experiment 1 showed that explicit ratings of event, action, and categorical relatedness were differentially predictive of healthy participants' choices, with action relatedness determining choices between Th+A and Th-A associations above and beyond event and categorical ratings. Experiment 2 focused more specifically on these Th+A vs. Th-A choices and demonstrated that participants with left temporo-parietal lesions, a brain region known to be involved in sensorimotor processing, were less likely than controls and tended to be less likely than patients with lesions sparing that region to use action relatedness in determining their choices. These data indicate that action knowledge plays a critical role in processing of thematic relations for manipulable artifacts. PMID:24672461

An integrated perspective on the relevant qualitative findings on the experience of screen time in youth can inform the development of hypotheses to be tested in future research and can guide the development of interventions to decrease sedentary behavior. The purpose of this qualitative metasynthesis was to explore parent, youth, and educational professionals' perceptions of barriers to, and facilitators of, reducing youth screen time. Qualitative metasynthesis techniques were used to analyze and synthesize 15 qualitative studies of screen time among youth (11-18 years) meeting inclusion criteria. The phrases, quotes, and/or author interpretations (i.e., theme or subtheme) were recorded in a data display matrix to facilitate article comparisons. Codes were collapsed into 23 categories of similar conceptual meaning and 3 overarching themes were derived using thematic analysis procedures. Study sample sizes ranged from 6 to 270 participants from 6 countries. Data collection methods included focus groups (n = 6), interviews (n = 4), focus group and interviews (n = 4), and naturalistic observation (n = 1) with youth and/or parents. Data analysis techniques included thematic analysis (n = 9), content analysis (n = 3), grounded theory (n = 1), observation (n = 1), and interpretive phenomenological analysis (n = 1). Three thematic categories were identified: (a) youth's norms-screen time is an integral part of daily life, and facilitates opportunities for entertainment, social interaction, and escapism; (b) family dynamics and parental roles-parents are conflicted and send mixed messages about the appropriate uses and amounts of screen time; and, (c) resources and environment-engagement in screen time is dependent on school, community, neighborhood, and home environmental contexts. Screen time is an established norm in many youth cultures, presenting barriers to behavior change. Parents recognize the importance of reducing youth screen time, but model and promote engagement themselves. For youth and parents, mutually agreed rules, limits, and parental monitoring of screen time were perceived as likely to be effective. (c) 2015 APA, all rights reserved).

For novel issues like food nanotechnology, media can play an important role in shaping the awareness and mental associations that underlie public opinion. Seeking to complement recent research exploring public opinion formation about food nanotechnology, this study tracks the evolution of U.S. newspaper coverage of food nanotechnology, identifying the descriptive and thematic traits that have characterized this coverage over time. We use a rigorous methodology to examine the levels of coverage, authorship patterns, and thematic emphases exhibited in the American journalistic narrative about this burgeoning application of nanoscience. Our findings indicate that U.S. newspaper coverage of food nanotechnology is relatively modest in terms of how often it has been covered, its thematic diversity, and the level of journalistic expertise from which it was produced. To our knowledge, this is the first study to empirically assess journalistic coverage of food nanotechnology. Copyright © 2010 Elsevier Ltd. All rights reserved.

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.
