Sample records for concept mapping strategy

  1. Concept mapping: an effective instructional strategy for diet therapy.

    Roberts, C M; Sucher, K; Perrin, D G; Rodriguez, S

    1995-08-01

    Concept mapping is an instructional strategy that requires learners to identify, graphically display, and link key concepts in instructional reading material. Although proven effective in numerous disciplines as a means to promote critical thinking and self-directed learning, concept mapping has not been tested in diet therapy. The objective of this study was to implement concept mapping as a small-group, cooperative learning strategy in an upper-division diet therapy course and to evaluate student attitudes about the effect of concept mapping on knowledge, self-directed learning, problem-solving, and collaborative skills. Students in the first semester (n = 27) initially learned course material by lecture (4 weeks) followed by an integrated mapping/lecture format (12 weeks); the second semester (n = 25) used an integrated mapping lecture format for the full 16 weeks. At the end of both semesters, students completed a 10-item original survey questionnaire. Responses for first (n = 25) and second (n = 21) semesters were analyzed independently. Results indicated that a majority of students thought participation in concept mapping enhanced knowledge of diet therapy principles (n = 19 of 25; 18 of 21), self-directed learning (n = 14 of 25; 18 of 21), critical thinking (n = 21 of 25; 14 of 21), problem-solving (n = 22 of 25; 16 of 21), and collaboration (n = 24 of 25; 20 of 21) skills. When noncooperation of teammates was a factor, concept mapping was viewed as more frustrating and time consuming than lecture. This study demonstrated concept mapping as an effective learning strategy for diet therapy; it improves students' ability to engage in self-directed learning, critical thinking, collaboration, and creative problem solving. Results suggest that concept mapping is most effective when accompanied with comprehensive training, coordinated lectures, instructor guidance, and long-term practice. PMID:7636083

    Daley, B J; Shaw, C R; Balistrieri, T; Glasenapp, K; Piacentine, L

    1999-01-01

    The purpose of this article is to describe a study that implemented concept maps as a methodology to teach and evaluate critical thinking. Students in six senior clinical groups were taught to use concept maps. Students created three concept maps over the course of the semester. Data analysis demonstrated a group mean score of 40.38 on the first concept map and 135.55 on the final concept map, for a difference of 98.16. The paired t value comparing the first concept map to the final concept map was -5.69. The data indicated a statistically significant difference between the first and final maps. This difference is indicative of the students' increase in conceptual and critical thinking. PMID:9921788

  6. Professional development strategies for teaching urban biology teachers to use concept maps effectively

    McGregor Petgrave, Dahlia M.

    Many teachers are not adequately prepared to help urban students who have trouble understanding conceptual ideas in biology because these students have little connection to the natural world. This study explored potential professional development strategies to help urban biology teachers use concept maps effectively with various topics in the biology curriculum. A grounded theory approach was used to develop a substantive professional development model for urban biology teachers. Qualitative data were collected through 16 semi-structured interviews of professional developers experienced in working with concept maps in the urban context. An anonymous online survey was used to collect quantitative data from 56 professional developers and teachers to support the qualitative data. The participants were from New York City, recruited through the NY Biology-Chemistry Professional Development Mentor Network and the NY Biology Teachers' Association. According to the participants, map construction, classroom applications, lesson planning, action research, follow-up workshops, and the creation of learning communities are the most effective professional development strategies. The interviewees also proposed English language learning strategies such as picture maps, native word maps, and content reading materials with underlined words. This study contributes to social change by providing a professional development model to use in planning workshops for urban teachers. Urban teachers improve their own conceptual understanding of biology while learning how to implement concept mapping strategies in the classroom. Students whose teachers are better prepared to teach biology in a conceptual manner have the potential of growing into more scientifically literate citizens.

  9. Using progressive concept maps as a strategy for teaching and learning in teacher education in Biology

    Conceição Aparecida Soares Mendonça

    2013-02-01

    Full Text Available This paper presents a study carried out with Biology teachers under training, and aimed at investigating how concept maps enabled meaningful learning. The work was motivated by the fact that future teachers presented difficulties learning various concepts. In this light, maps can be a valuable instrument for the diagnosis and assessment of learning, enabling better concept learning. Thus, during our pedagogical intervention, we have strived to identify the conceptual evolution of students, through the construction of concept maps before, during and after the study of a proposed theme. The qualitative analysis of the produced maps focused on the processes of teaching, learning and assessment. At this point, the goal was to investigate whether or not students were able to relate the concepts under study, according to the principles of progressive differentiation and integrative reconcilitation. This was done while searching for evidences of meaningful learning.The pedagogical intervention lasted for 45 hours (8 meetings, during which a Zoology topic, concept Elephants was studied at a State university of Brazil. The qualitative analysis of the maps created by the learners has shown, in 58% of the cases, that there was an evolution of the learnersʼ knowledge of the theme. Obtained results suggest that maps have an efficient functional action and help improve the professional profile under formation.

    Dawson, Anna P; Cargo, Margaret; Stewart, Harold; Chong, Alwin; Daniel, Mark

    2013-02-01

    Aboriginal Australians, including Aboriginal Health Workers (AHWs), smoke at rates double the non-Aboriginal population. This study utilized concept mapping methodology to identify and prioritize culturally relevant strategies to promote smoking cessation in AHWs. Stakeholder participants included AHWs, other health service employees and tobacco control personnel. Smoking cessation strategies (n = 74) were brainstormed using 34 interviews, 3 focus groups and a stakeholder workshop. Stakeholders sorted strategies into meaningful groups and rated them on perceived importance and feasibility. A concept map was developed using multi-dimensional scaling and hierarchical cluster analyses. Ten unique clusters of smoking cessation strategies were depicted that targeted individuals, family and peers, community, workplace and public policy. Smoking cessation resources and services were represented in addition to broader strategies addressing social and environmental stressors that perpetuate smoking and make quitting difficult. The perceived importance and feasibility of clusters were rated differently by participants working in health services that were government-coordinated compared with community-controlled. For health service workers within vulnerable populations, these findings clearly implicate a need for contextualized strategies that mitigate social and environmental stressors in addition to conventional strategies for tobacco control. The concept map is being applied in knowledge translation to guide development of smoking cessation programs for AHWs. PMID:23221591

  13. The use of concept mapping to identify community-driven intervention strategies for physical and mental health.

    Vaughn, Lisa M; Jacquez, Farrah; McLinden, Daniel

    2013-09-01

    Research that partners with youth and community stakeholders increases contextual relevance and community buy-in and therefore maximizes the chance for intervention success. Concept mapping is a mixed-method participatory research process that accesses the input of the community in a collaborative manner. After a school-wide health needs assessment at a low-income, minority/immigrant K-8 school identified bullying and obesity as the most important health issues, concept mapping was used to identify and prioritize specific strategies to address these two areas. Stakeholders including 160 K-8 students, 33 college students working in the school, 35 parents, 20 academic partners, and 22 teachers/staff brainstormed strategies to reduce and prevent obesity and bullying. A smaller group of stakeholders worked individually to complete an unstructured sorting of these strategies into groups of similar ideas, once for obesity and again for bullying. Multidimensional scaling and cluster analysis was applied to the sorting data to produce a series of maps that illustrated the stakeholders' conceptual thinking about obesity and bullying prevention strategies. The maps for both obesity and bullying organized specific strategies into themes that included education, parental role, teacher/school supervision, youth role, expert/professional role, and school structure/support.

  14. A Concept-Mapping Strategy for Assessing Conceptual Change in a Student-Directed, Research-Based Geoscience Course

    Rebich, S.

    2003-12-01

    The concept mapping technique has been proposed as a method for examining the evolving nature of students' conceptualizations of scientific concepts, and promises insight into a dimension of learning different from the one accessible through more conventional classroom testing techniques. The theory behind concept mapping is based on an assumption that knowledge acquisition is accomplished through "linking" of new information to an existing knowledge framework, and that meaningful (as opposed to arbitrary or verbatim) links allow for deeper understanding and conceptual change. Reflecting this theory, concept maps are constructed as a network of related concepts connected by labeled links that illustrate the relationship between the concepts. Two concepts connected by one such link make up a "proposition", the basic element of the concept map structure. In this paper, we examine the results of a pre- and post-test assessment program for an upper-division undergraduate geography course entitled "Mock Environmental Summit," which was part of a research project on assessment. Concept mapping was identified as a potentially powerful assessment tool for this course, as more conventional tools such as multiple-choice tests did not seem to provide a reliable indication of the learning students were experiencing as a result of the student-directed research, presentations, and discussions that make up a substantial portion of the course. The assessment program began at the beginning of the course with a one-hour training session during which students were introduced to the theory behind concept mapping, provided with instructions and guidance for constructing a concept map using the CMap software developed and maintained by the Institute for Human and Machine Cognition at the University of West Florida, and asked to collaboratively construct a concept map on a topic not related to the one to be assessed. This training session was followed by a 45-minute "pre-test" on the

  15. Online Exhibits & Concept Maps

    Douma, M.

    2009-12-01

    Presenting the complexity of geosciences to the public via the Internet poses a number of challenges. For example, utilizing various - and sometimes redundant - Web 2.0 tools can quickly devour limited time. Do you tweet? Do you write press releases? Do you create an exhibit or concept map? The presentation will provide participants with a context for utilizing Web 2.0 tools by briefly highlighting methods of online scientific communication across several dimensions. It will address issues of: * breadth and depth (e.g. from narrow topics to well-rounded views), * presentation methods (e.g. from text to multimedia, from momentary to enduring), * sources and audiences (e.g. for experts or for the public, content developed by producers to that developed by users), * content display (e.g. from linear to non-linear, from instructive to entertaining), * barriers to entry (e.g. from an incumbent advantage to neophyte accessible, from amateur to professional), * cost and reach (e.g. from cheap to expensive), and * impact (e.g. the amount learned, from anonymity to brand awareness). Against this backdrop, the presentation will provide an overview of two methods of online information dissemination, exhibits and concept maps, using the WebExhibits online museum (www.webexhibits.org) and SpicyNodes information visualization tool (www.spicynodes.org) as examples, with tips on how geoscientists can use either to communicate their science. Richly interactive online exhibits can serve to engage a large audience, appeal to visitors with multiple learning styles, prompt exploration and discovery, and present a topic’s breadth and depth. WebExhibits, which was among the first online museums, delivers interactive information, virtual experiments, and hands-on activities to the public. While large, multidisciplinary exhibits on topics like “Color Vision and Art” or “Calendars Through the Ages” require teams of scholars, user interface experts, professional writers and editors

    Regis, Alberto; Albertazzi, Pier Giorgio; Roletto, Ezio

    1996-11-01

    This article presents and illustrates a proposed application of concept maps in chemistry teaching in high schools. The students were provided with the "concept lables" necessary for map building in three different ways. The analysis of the students' maps at different stages of the learning process led to the recognition of the three types of cognitive events which seem to correspond to the same number of restructuring stages in the conceptual organization. This can enable the teacher to characterize the changes produced in the learners' conceptions by teaching / learning activities. Three examples of the use of concept maps in chemistry teaching are reported and discussed with reference to: atomic structure, oxidation-reduction and thermodynamics.

    In this paper we discuss the concept of ecological strategy in relation to cognitive artefacts that reflect the expressive power of learners engaged in the development of significant knowledge paths. Our experiments show that learners strive to make sense of the fragmentary information surrounding them and in this endeavour they may benefit from the creation of knowledge maps, i.e. branched structures of knowledge that depart from a central node, a starting point or a homepage. In the course ...

    2012-01-01

      The present study applies Dr. He Yuanjian’s CMT (Conceptual Mapping Theory) to focus on the strategy use of translating Chinese folklore concepts in Hong Lou Meng (i.e. indigenous concepts related to etiquettes and customs) by Yang Xianyi and his wife Gladys Yang on the observations of the translators’strategies and the distributional tendencies of translation strategies so as to testify CMT on empirical grounds. Whether it holds true that the preservation of the alien source concepts through translation depends on how successfully they are mapped into the target conceptual system leads to the attempts to study on the distributional tendency of translation strategies of translation tasks, especially, of translating folkloric concepts in this paper. As a result, the tentative outcome of the data observed supports that the concept-mediation theoretic approach to translation pro⁃cess seems able to account for how cognitive constraints affect the production of mapping the unshared concepts.

  9. Teaching, Designing, and Organizing: Concept Mapping for Librarians

    April Colosimo

    2012-06-01

    Full Text Available Concept maps are graphical representations of relationships among concepts that can be an effective tool for teaching, designing, and organizing information in a variety of library settings. First, concept mapping can be used wherever training or formal teaching occurs as a visual aid to explain complex ideas. They can also help learners articulate their understanding of a subject area when they create their own concept maps. When using concept mapping as a teaching tool, students may have a more meaningful learning experience when they add information to a concept map that is based on their current knowledge. Next, concept maps are an effective design tool for librarians who are planning projects. They can also serve as a reference point for project implementation and evaluation. The same is true for the design of courses, presentations, and library workshops. A concept map based on the content of a course, for example, is valuable when selecting learning outcomes and strategies for teaching and assessment. Finally, concept mapping can used as a method for capturing tacit or institutional knowledge through the creation and organization of ideas and resources. Librarians can collaborate on concept maps with each other or with non-librarian colleagues to facilitate communication. Resulting maps can be published online and link to documentation and relevant resources. This paper provides an overview of the literature related to concept mapping in libraries. Concrete applications and examples of concept mapping for teaching and learning, designing, and organizing in library settings are then elaborated. The authors draw from their own success and experience with different concept mapping methods and software programs.

  10. Using Concept Mapping to Develop a Strategy for Self-Management Support for Underserved Populations Living With Chronic Conditions, British Columbia, August 2013–June 2014

    Bergeron, Kim; Pérez, Guillermina

    2015-01-01

    Introduction Self-management support (SMS) is an essential component of public health approaches to chronic conditions. Given increasing concerns about health equity, the needs of diverse populations must be considered. This study examined potential solutions for addressing the gaps in self-management support initiatives for underserved populations. Methods Stakeholders representing government, nongovernment organizations, Aboriginal communities, health authorities, medical practices, and research institutions generated, sorted, and rated ideas on what could be done to improve self-management support for underserved populations. Concept mapping was used to facilitate the collection and organization of the data and to generate conceptual maps. Results Participants generated 92 ideas that were sorted into 11 clusters (foster partnerships, promote integrated community care, enhance health care provider training, shift government policy, support community development, increase community education, enable client engagement, incorporate client support systems, recognize client capacity, tailor self-management support programs, and develop client skills, training, and tools) and grouped into system, community, and individual levels within a partnership framework. Conclusion The strategy can stimulate public health dialogue and be a roadmap for developing SMS initiatives. It has the potential to address SMS and chronic condition inequities in underserved populations in several ways: 1) by targeting populations that have greater inequities, 2) by advocating for shifts in government policies that create and perpetuate inequities, 3) by promoting partnerships that may increase the number of SMS initiatives for underserved groups, and 4) by promoting training and engagement that increase the relevance, uptake, and overall effectiveness of SMS.

    Nancy L. Gallenstein

    2013-02-01

    Full Text Available Concept mapping is an inquiry technique that provides students at all ages with opportunities to demonstrate learning through performance. A concept map refers to a graphic/visual representation of concepts with linking connections that show various relationships between concepts (Novak & Gowin, 1984. Assessment is an ongoing process integrated with instruction across subject areas. The National Council of Teachers of Mathematics (NCTM emphasizes that assessment should focus on both the enhancement of student learning as well as serve as a valuable tool for making instructional decisions (NCTM, 2000. Assessment activities can take on a variety of forms, one being performance tasks. In this manuscript, an explanation of concept mapping is provided for learners ages 3 – 12 along with several examples of concept maps for young learners, including examples from an assessment project in the subject area of mathematics. Also presented are the numerous benefits of the concept mapping technique for both students and teachers.

  13. Evaluation of concept mapping in an associate degree nursing program.

    Abel, Willie Mae; Freeze, Martha

    2006-09-01

    The purpose of this project was to evaluate concept mapping as a clinical teaching-learning activity that reflects critical thinking by promoting identification of nonlinear relationships among the components of the nursing process. The sample involved 28 associate degree nursing students from one graduating class. Students completed one map each in the second and fourth semesters and two maps in the fifth semester, for a total of four concept maps. The students' learning activity was to create a concept map on a blank sheet of paper describing the clients' physiological and psychosocial needs and nursing care and the relationships among concepts. As students progressed through the curriculum, there was a steady increase in the mean scores and the average number of cross-links in their concept maps. Cross-links indicated students' ability to use nonlinear thinking to identify relationships among concepts. The results of this study support the use of concept maps as an effective teaching-learning activity and support concept mapping as an evidence-based nursing education strategy. PMID:17002082

  16. Concept Mapping for Higher Order Thinking

    Susan Marie Zvacek

    2013-02-01

    Full Text Available Engineering education is facing a changing world in which how one thinks is becoming more important than what one thinks; that is, our course content is important but constantly changing and we need to help students learn how to think about that content.Today’s students have grown accustomed to immediate rewards, multi-channel stimuli, and rapid-fire communications.  As a result, they are often impatient and suffer a lack of focus. When reflection is called for in the learning process - a time consuming practice - students may find it difficult to overcome the conflict between their typically speedy management of priorities and the focused, time-intensive thinking required to acquire a strong foundation of declarative knowledge.Therefore, the exploration of tools to facilitate the formation of deep knowledge structures is essential. One instructional strategy that shows promise is the use of concept mapping, a learning activity that requires students to explain their understanding of important ideas and the relationships among those ideas.  This paper describes a pilot project to integrate concept mapping into a Mechanical Engineering Course and the preliminary results of that project.This project has been established within the Working Group of “Tools for Developing High Order Thinking Skills”, of the Portuguese Society for Engineering Education, in which the first author is the leader and the other two co-authors, are working group members

  18. Mapping your innovation strategy.

    Anthony, Scott D; Eyring, Matt; Gibson, Lib

    2006-05-01

    In the complex sport of American football, teams rely on playbooks as thick as the Manhattan phone directory. But when it comes to creating innovative growth businesses-which is at least as complicated as professional football--most companies have not developed detailed game plans. Indeed, many managers have concluded that a fog enshrouds the world of innovation, obscuring high-potential opportunities. The authors believe that companies can penetrate that fog by developing growth strategies based on disruptive innovations, as defined by Clayton Christensen. Such innovations conform to a pattern: They offer an entirely new solution; they perform adequately along traditional dimensions and much better along other dimensions that matter more to target customers; and they are not initially appealing to powerful incumbents. Companies can develop customized checklists, or playbooks, by combining this basic pattern with analysis of major innovations in their markets. The key early on is to focus not on detailed financial estimates--which will always guide companies toward the markets most hostile to disruptive innovations--but on how well the innovation fits the pattern of success. It's also crucial to encourage flexibility: Companies must be willing to kill projects that are going nowhere, exempt innovations from standard development processes, and avoid burdening project teams with extra financing, which can keep them heading in the wrong direction. Companies can create competitive advantage by becoming champions at defining the pattern of successful innovations and executing against it. But as that pattern becomes obvious--and others emerge-building a sustainable advantage on innovation competencies will again prove elusive. PMID:16649702

  2. The comparative effect of individually-generated vs. collaboratively-generated computer-based concept mapping on science concept learning

    Kwon, So Young

    Using a quasi-experimental design, the researcher investigated the comparative effects of individually-generated and collaboratively-generated computer-based concept mapping on middle school science concept learning. Qualitative data were analyzed to explain quantitative findings. One hundred sixty-one students (74 boys and 87 girls) in eight, seventh grade science classes at a middle school in Southeast Texas completed the entire study. Using prior science performance scores to assure equivalence of student achievement across groups, the researcher assigned the teacher's classes to one of the three experimental groups. The independent variable, group, consisted of three levels: 40 students in a control group, 59 students trained to individually generate concept maps on computers, and 62 students trained to collaboratively generate concept maps on computers. The dependent variables were science concept learning as demonstrated by comprehension test scores, and quality of concept maps created by students in experimental groups as demonstrated by rubric scores. Students in the experimental groups received concept mapping training and used their newly acquired concept mapping skills to individually or collaboratively construct computer-based concept maps during study time. The control group, the individually-generated concept mapping group, and the collaboratively-generated concept mapping group had equivalent learning experiences for 50 minutes during five days, excepting that students in a control group worked independently without concept mapping activities, students in the individual group worked individually to construct concept maps, and students in the collaborative group worked collaboratively to construct concept maps during their study time. Both collaboratively and individually generated computer-based concept mapping had a positive effect on seventh grade middle school science concept learning but neither strategy was more effective than the other.

  16. Concept mapping: Impact on content and organization of technical writing in science

    Conklin, Elaine

    The purpose of this quasi-experimental study was to compare the relationship between concept mapping and the content and organization of technical writing of ninth grade biology students. All students in the study completed a prewriting assessment. The experimental group received concept map instruction while the control group performed alternate tasks. After instruction, both groups completed the postwriting assessment and mean differences were compared using the t statistic for independent measures. Additionally, scores on the concept map were correlated to the scores on the postwriting assessment using the Pearson correlation coefficient. Finally, attitudes toward using concept mapping as a prewriting strategy were analyzed using the t statistic for repeated measures. Concept mapping significantly improved the depth of content; however, no statistical significance was detected for organization. Students had a significantly positive change in attitude toward using concept mapping to plan a writing assessment, organize information, and think creatively. The findings indicated concept mapping had a positive effect on the students' abilities to select concepts appropriate to respond to a writing prompt, integrate facts into complete thoughts and ideas, and apply it in novel situations. Concept maps appeared to facilitate learning how to process information and transform it into expository writing. Sustained practice in designing concept maps may influence organization as well as content. Developing a systematic approach to synthesize well-organized and coherent arguments in response to a writing task is an invaluable communication skill that has implications for the learner across disciplines and prepares them for higher education and the workforce.

  17. Concept Mapping Using Cmap Tools to Enhance Meaningful Learning

    Cañas, Alberto J.; Novak, Joseph D.

    Concept maps are graphical tools that have been used in all facets of education and training for organizing and representing knowledge. When learners build concept maps, meaningful learning is facilitated. Computer-based concept mapping software such as CmapTools have further extended the use of concept mapping and greatly enhanced the potential of the tool, facilitating the implementation of a concept map-centered learning environment. In this chapter, we briefly present concept mapping and its theoretical foundation, and illustrate how it can lead to an improved learning environment when it is combined with CmapTools and the Internet. We present the nationwide “Proyecto Conéctate al Conocimiento” in Panama as an example of how concept mapping, together with technology, can be adopted by hundreds of schools as a means to enhance meaningful learning.

  1. Designing a Multichannel Map Service Concept

    Hanna-Marika Halkosaari

    2013-01-01

    Full Text Available This paper introduces a user-centered design process for developing a multichannel map service. The aim of the service is to provide hikers with interactive maps through several channels. In a multichannel map service, the same spatial information is available through various channels, such as printed maps, Web maps, mobile maps, and other interactive media. When properly networked, the channels share a uniform identity so that the user experiences the different channels as a part of a single map service. The traditional methods of user-centered design, such as design probes, personas, and scenarios, proved useful even in the emerging field of developing multichannel map services. The findings emphasize the need to involve users and multidisciplinary teams in the conceptual phases of designing complex services aimed at serving various kinds of users.

  6. Mapping Concepts of Agency in Educational Contexts.

    Matusov, Eugene; von Duyke, Katherine; Kayumova, Shakhnoza

    2016-09-01

    The purpose of this conceptual paper is to explore and map the "espoused theories" (Argyris and Schön 1978) of agency used in educational contexts. More precisely, we limit the focus on the normative view of student agency assumed within dominant school practices, desired by educational practitioners, leaving out non-normative emerging agencies such as student agency of resistance. Agency is a "tricky" concept, and often scholars who use the concept of agency do not define or operationalize it (e.g., Archer 2000). One reason is that there is no consensus among scholars about the notion of agency, especially when applied to educational contexts (Hitlin and Elder Sociological Theory, 25 (2), 170-191, 2007). Moreover, the recent neoliberal framing of individuals' agency as fully autonomous, flexible, and self-entrepreneur is adding the dilemma of agency manipulation in the sphere of education (Gershon 2011; Sidorkin 2004). To tackle this dilemma in educational contexts, we suggest to further interrogating the normative notion of agency in all its modes and develop a more nuanced conceptualization. We hope that such conceptualization would produce an understanding of the diverse manifestations and definitions of agency within a human ideal, educational content, behaviors, and social settings. We observed diverse uses of the normative term "agency" in educational discourse. We examined the term as used by researchers and practitioners. We also looked at the different ways it has been used in philosophical discussions of education, political framing of the civic role of schooling, disciplinary policy statements, school mission statements, and in everyday common use. It is worthy to note that our categorization of the use and meaning of the normative term "agency" depends on the scholars' epistemological paradigmatic assumptions, socio-political and historical situatedness, and ontological projects being translated into diverse scholarships of education. As a result of

  7. CONCEPT MAPS – IMPROVEMENT TOOL FOR ACCOUNTING INFORMATION

    Oana DRĂGAN

    2014-12-01

    Full Text Available Concept maps, viewed as an innovative method for learning and evolution, are used to synthesize the knowledge of the participants to the learning process and are based on the main concepts and the relationship between them. They offer a visual representation of the information held by an individual, caught through his ability to synthesize the notions/the key concepts. The current study intends to show the importance and efficiency of using the concept maps in economics, especially in the accounting department, a method designed to settle the learning process and, also, to offer a sustainable value. The current empirical study is based on the manner in which the accounting knowledge is displayed by a sample group of 19 practitioners. The originality, the relevance of the concept maps method is underlined by the idea of the practitioners creating their own concept maps designed to point out the importance of the cognitive structure when describing the relationships between different accounting principles.

  9. Understanding of earth and space science concepts: Strategies for concept building in elementary teacher preparation

    Bulunuz, Nermin

    Research on conceptual change provides strong evidence that not only children but also many adults have incorrect or incomplete understanding of science concepts. This mixed methods study was concerned with preservice and inservice teachers' understanding of six earth and space science concepts commonly taught in elementary school: reasons for seasons, phases of the moon, reasons for the wind, the rock cycle, soil formation, and earthquakes. The first part of the study determined and compared the level of conceptual understanding held by both groups on topics they will need to teach in the Georgia Performance Standards [GPS]. The second part focused on whether readings or hands-on learning stations, in some cases combined with concept mapping, improves preservice teachers' understanding of these concepts. The third part described the application of conceptual change strategies of one group of preservice teachers during their field placements. The overall sample was two cohorts of preservice teachers, one cohort of preservice teachers from an alternative initial certification program, and two masters' cohorts consisting of inservice teachers. Four data sources were: a six item open-ended survey, concept maps, the field assignments, and the researcher's field notes. Rubrics were used to score answers to each survey question. Concept map scores were calculated based on the criteria developed by Novak and Gowin (1984). The first part of the study shows that both preservice and inservice teachers have low conceptual understanding of the earth science concepts taught in elementary school. Independent samples t-tests results indicate that both groups have similar understanding about these concepts. A two way ANOVA with repeated measures analysis demonstrated that readings and learning stations are both successful in building preservice teacher's understanding and that benefits from the hands-on learning stations approached statistical significance. A paired samples t

    2014-07-01

    The NASA Science Mission Directorate Heliophysics Science Education and Public Outreach Forum team has created a set of Heliophysics Concept Maps. The concepts are based on content related to the three major questions in the NASA Heliophysics Science Roadmap: What causes the Sun to vary? How do the Earth and the heliosphere respond? What are the impacts on humanity? These maps tie into the AAAS Project 2061 Benchmarks for Scientific Literacy, a set of K-12 learning goals that are widely used by education professionals for curriculum development and program planning. The purpose of this effort was to identify key concepts related to heliophysics and map their progression to show how students' understanding of heliophysics might develop from kindergarten through higher education. This effort creates more comprehensive maps specific to heliophysics that provide content at a deeper level than what is in the existing Benchmarks. It also extends the concept maps to higher education, an audience not included in the Benchmarks.

    2012-10-01

    Many efforts to implement evidence-based programs do not reach their full potential or fail due to the variety of challenges inherent in dissemination and implementation. This article describes the use of concept mapping-a mixed method strategy-to study implementation of behavioral health innovations and evidence-based practice (EBP). The application of concept mapping to implementation research represents a practical and concise way to identify and quantify factors affecting implementation, develop conceptual models of implementation, target areas to address as part of implementation readiness and active implementation, and foster communication among stakeholders. Concept mapping is described and a case example is provided to illustrate its use in an implementation study. Implications for the use of concept mapping methods in both research and applied settings towards the dissemination and implementation of behavioral health services are discussed. PMID:22892987

    2016-09-01

    Nurses confront complex problems and decisions that require critical thinking in order to identify patient needs and implement best practices. An active strategy for teaching students the skills to think critically is the concept map. This study explores the development of critical thinking among nursing students in a required pathophysiology and pharmacology course during the first year of a Bachelor of Science in Nursing in response to concept mapping as an interventional strategy, using the Health Education Systems, Incorporated critical thinking test. A two-group experimental study with a pretest and posttest design was used. Participants were randomly divided into a control group (n = 42) taught by traditional didactic lecturing alone, and an intervention group (n = 41), taught by traditional didactic lecturing with concept mapping. Students in the concept mapping group performed much better on the Health Education Systems, Incorporated than students in the control group. It is recommended that deans, program directors, and nursing faculties evaluate their curricula to integrate concept map teaching strategies in courses in order to develop critical thinking abilities in their students.

  20. ENGLISH LANGUAGE TEACHING WITH AN ELECTRONIC CONCEPT MAPPING

    Erdogan Tezc

    2007-06-01

    Full Text Available Educational technologies have contributed greatly to the improvement of the process of education. Besides contributing to education directly, the development in new technologies made it almost compulsory to bring new approaches in teaching methods. Among these contributions can be mentioned the application of Internet Technologies in teaching. There is an ever-increasing positive impact on learning of combining technological materials with teaching methods, or using them as teaching materials. Electronic concept mapping can be considered as a teaching method to raise motivation and meaningfulness with its features being contextual, visual, multi-dimensional and interactive. Concept maps are of significant structure in language teaching because of their cognitive complexity, coherence and taxonomic organization. As concepts are contextual in English, this will create an appropriate atmosphere for it to be learnt together with its phonetic and linguistic structure. In this study a model of e-concept maps has been used as an alternative teaching method.

  1. Integrating collaborative concept mapping in case based learning

    Alfredo Tifi

    2013-03-01

    Full Text Available Different significance of collaborative concept mapping and collaborative argumentation in Case Based Learning are discussed and compared in the different perspectives of answering focus questions, of fostering reflective thinking skills and in managing uncertainty in problem solving in a scaffolded environment. Marked differences are pointed out between the way concepts are used in constructing concept maps and the way meanings are adopted in case based learning through guided argumentation activities. Shared concept maps should be given different scopes, as for example a as an advance organizer in preparing a background system of concepts that will undergo transformation while accompanying the inquiry activities on case studies or problems; b together with narratives, to enhance awareness of the situated epistemologies that are being entailed in choosing certain concepts during more complex case studies, and c after-learning construction of a holistic vision of the whole domain by means of the most inclusive concepts, while scaffoldedcollaborative writing of narratives and arguments in describing-treating cases could better serve as a source of situated-inspired tools to create-refine meanings for particular concepts.

  2. Construction of concept maps as tool for Biochemistry learning

    Silvia Lopes de Menezes

    2006-07-01

    Full Text Available The use of concept maps on the teaching of sciences has been object of worldwide research with different purposes: to detect the previous knowledge of the students on certain topics or to evaluate learning, among others. Based on Ausubel´s cognitive psychology, concept maps assume that the learning is accomplished by assimilation of new concepts and propositions to the students´ cognitive structure, contributing to establish links between the previous and new knowledge. It is especially interesting on the approach of interdisciplinary issues, as many studied in Biochemistry.The relevance of the use of concept maps on biochemistry learning was evaluated on a thirty-hour undergraduation optional course, with interdisciplinary topics, which are not usually included on introductory Biochemistry courses. The course Biochemistry of Animal Venoms was structured in seven module where the biochemical action mechanisms of the venoms of Crotalus sp (south american rattlesnake, Bothrops sp (jararaca, Loxosceles sp (brown spider, Tityus sp (yellow scorpion, Phoneutria sp (armed spider, Apis mellifera (honey bee and Latrodectus sp (black widowwere discussed.

  11. Enhancing Collaborative and Meaningful Language Learning Through Concept Mapping

    Marriott, Rita De Cássia Veiga; Torres, Patrícia Lupion

    This chapter aims to investigate new ways of foreign-language teaching/learning via a study of how concept mapping can help develop a student's reading, writing and oral skills as part of a blended methodology for language teaching known as LAPLI (Laboratorio de Aprendizagem de LInguas: The Language Learning Lab). LAPLI is a student-centred and collaborative methodology which encourages students to challenge their limitations and expand their current knowledge whilst developing their linguistic and interpersonal skills. We explore the theories that underpin LAPLI and detail the 12 activities comprising its programme with specify reference to the use of "concept mapping". An innovative table enabling a formative and summative assessment of the concept maps is formulated. Also presented are some of the qualitative and quantitative results achieved when this methodology was first implemented with a group of pre-service students studying for a degree in English and Portuguese languages at the Catholic University of Parana (PUCPR) in Brazil. The contribution of concept mapping and LAPLI to an under standing of language learning along with a consideration of the difficulties encountered in its implementation with student groups is discussed and suggestions made for future research.

    Nicoll, Gayle A.

    2000-09-01

    Based on the constructivist model of learning, this research is a qualitative and quantitative strategy for investigating the extent to which chemistry students made connections between material presented in different chapters or courses as a function of their exposure to chemistry topics. Specifically, qualitative interviews were conducted once during the process of several semester long chemistry courses to determine the degree to which students had made links between the underlying concepts of electrons, bonding, and molecular geometry, which are all taught in the general chemistry curriculum. Concept maps drawn from the interviews were used as the analytical tool to assess subjects' links between these concepts. The study consisted of two parts, in which the degree of linkage was compared: (1) from students exposed to concept maps in class to those not exposed to concept maps, and (2) from freshmen chemistry level students through senior level chemistry students.

  19. Challenges and complications in neighborhood mapping: from neighborhood concept to operationalization

    Deng, Yongxin

    2016-05-01

    This paper examines complications in neighborhood mapping and corresponding challenges for the GIS community, taking both a conceptual and a methodological perspective. It focuses on the social and spatial dimensions of the neighborhood concept and highlights their relationship in neighborhood mapping. Following a brief summary of neighborhood definitions, five interwoven factors are identified to be origins of neighborhood mapping difficulties: conceptual vagueness, uncertainty of various sources, GIS representation, scale, and neighborhood homogeneity or continuity. Existing neighborhood mapping methods are grouped into six categories to be assessed: perception based, physically based, inference based, preexisting, aggregated, and automated. Mapping practices in various neighborhood-related disciplines and applications are cited as examples to demonstrate how the methods work, as well as how they should be evaluated. A few mapping strategies for the improvement of neighborhood mapping are prescribed from a GIS perspective: documenting simplifications employed in the mapping procedure, addressing uncertainty sources, developing new data solutions, and integrating complementary mapping methods. Incorporation of high-resolution data and introduction of more GIS ideas and methods (such as fuzzy logic) are identified to be future opportunities.

  1. Novel concept on antiviral strategies to dengue.

    Lo, Yu-Chih; Perng, Guey Chuen

    2016-06-01

    Recent evidence has revealed that asymptomatic and/or persistent dengue virus (DENV) infections play a role in the cycling pattern of dengue outbreaks. These findings add a new dimension to the continually evolving search for effective prevention strategies in dengue. Disappointing outcomes of clinical trials in anti-dengue modalities have become commonplace. These failures may result from confounding variables and/or unresolved scientific issues that surround dengue, including the replication cycle of DENV in a natural setting, the target cells and reservoir for viral replication in vivo, and the effect of asymptomatic/persistent carriers in the dissemination of dengue. This article sets forth to address these issues using the most updated information available in the literature and to propose a novel antiviral strategy for the prevention and control of dengue.

  3. Concept mapping as an empowering method to promote learning, thinking, teaching and research

    Mauri Kalervo Åhlberg

    2013-01-01

    Full Text Available Results and underpinning of over twenty years of research and development program of concept mapping is presented. Different graphical knowledge presentation tools, especially concept mapping and mind mapping, are compared. There are two main dimensions that differentiate graphical knowledge presentation methods: The first dimension is conceptual explicitness: from mere concepts to flexibly named links and clear propositions in concept maps. The second dimension in the classification system I am suggesting is whether there are pictures or not. Åhlbergʼs and his research groupʼs applications and developments of Novakian concept maps are compared to traditional Novakian concept maps. The main innovations include always using arrowheads to show direction of reading the concept map. Centrality of each concept is estimated from number of links to other concepts. In our empirical research over two decades, number of relevant concepts, and number of relevant propositions in studentsʼ concept maps, have been found to be the best indicators and predictors of meaningful learning. This is used in assessment of learning. Improved concept mapping is presented as a tool to analyze texts. The main innovation is numbering the links to show order of reading the concept map and to make it possible to transform concept map back to the original prose text as closely as possible. In Åhlberg and his research groupʼs research, concept mapping has been tested in all main phases of research, teaching and learning.

  12. The Effect of Concept Mapping on Student Understanding and Correlation with Student Learning Styles

    Mosley, William G.

    This study investigated the use of concept mapping as a pedagogical strategy to promote change in the learning styles of pre-nursing students. Students' individual learning styles revealed two subsets of students; those who demonstrated a learning style that favors abstract conceptualization and those who demonstrated a learning style that favors concrete experience. Students in the experimental groups performed concept mapping activities designed to facilitate an integrative understanding of interactions between various organ systems of the body while the control group received a traditional didactic instruction without performing concept mapping activities. Both qualitative and quantitative data were collected in order to measure differences in student achievement. Analysis of the quantitative data revealed no significant change in the learning styles of students in either the control or experimental groups. Learning style groups were analyzed qualitatively for recurring or emergent themes that students identified as facilitating their learning. An analysis of qualitative data revealed that most students in the pre-nursing program were able to identify concepts within the class based upon visual cues, and a majority of these students exhibited the learning style of abstract conceptualization. As the laboratory experience for the course involves an examination of the anatomical structures of the human body, a visual identification of these structures seemed to be the most logical method to measure students' ability to identify anatomical structures.

  19. How good is my concept map? Am I a good Cmapper?

    Alberto J. Cañas

    2015-03-01

    Full Text Available There have been many efforts reported in the literature to score or rate the quality of concept maps. In many cases the objective was to standardize procedures for grading student concept maps, but other efforts have served a variety of purposes, including guiding workshop participants to construct better concept maps or monitoring the advances in concept mapping techniques on a large population of users. We examine some of the criteria used by others for rating or scoring concept maps as “good” and propose a scheme that takes into account both graphical structure criteria and semantic or subject matter accuracy that we propose can lead to better, “excellent” concept maps. It has been said that presentations that are concise but capture the complexity of the content involved are elegant—and producing these kinds of concept maps should be our goal.

    Femicide, defined as the killings of females by males because they are females, is becoming recognized worldwide as an important ongoing manifestation of gender inequality. Despite its high prevalence or widespread prevalence, only a few countries have specific registries about this issue. This study aims to assemble expert opinion regarding the strategies which might feasibly be employed to promote, develop and implement an integrated and differentiated femicide data collection system in Europe at both the national and international levels. Concept mapping methodology was followed, involving 28 experts from 16 countries in generating strategies, sorting and rating them with respect to relevance and feasibility. The experts involved were all members of the EU-Cost-Action on femicide, which is a scientific network of experts on femicide and violence against women across Europe. As a result, a conceptual map emerged, consisting of 69 strategies organized in 10 clusters, which fit into two domains: "Political action" and "Technical steps". There was consensus among participants regarding the high relevance of strategies to institutionalize national databases and raise public awareness through different stakeholders, while strategies to promote media involvement were identified as the most feasible. Differences in perceived priorities according to the level of human development index of the experts' countries were also observed. PMID:26859885

Results: Despite the significant difference between the mean pre-, post- and retention test scores (P<0.001, there was no significant correlation between these results and the nurses’ gender. A negative significant association was found between age and improved post test scores (P=0.02. Work experience had a significant positive effect on post test score improvement (P<0.001. Conclusion: This study revealed that the concept mapping strategy had a significant effect on the clinical decision making skills of nurses. However, further research on a larger sample size is recommended to confirm the results.

    2012-01-01

    Purpose:This study aims to discuss the strategies for mapping from Dewey Decimal Classification(DDC)numbers to Chinese Library Classification(CLC)numbers based on co-occurrence mapping while minimizing manual intervention.Design/methodology/approach:Several statistical tables were created based on frequency counts of the mapping relations with samples of USMARC records,which contain both DDC and CLC numbers.A manual table was created through direct mapping.In order to find reasonable mapping strategies,the mapping results were compared from three aspects including the sample size,the choice between one-to-one and one-to-multiple mapping relations,and the role of a manual mapping table.Findings:Larger sample size provides more DDC numbers in the mapping table.The statistical table including one-to-multiple DDC-CLC relations provides a higher ratio of correct matches than that including only one-to-one relations.The manual mapping table cannot produce a better result than the statistical tables.Therefore,we should make full use of statistical mapping tables and avoid the time-consuming manual mapping as much as possible.Research limitations:All the sample sizes were small.We did not consider DDC editions in our study.One-to-multiple DDC-CLC relations in the records were collected in the mapping table,but how to select one appropriate CLC number in the matching process needs to be further studied.Practical implications:The ratio of correct matches based on the statistical mapping table came up to about 90%by CLC top-level classes and 76%by the second-level classes in our study.The statistical mapping table will be improved to realize the automatic classification of e-resources and shorten the cataloging cycle significantly.Originality/value:The mapping results were investigated from different aspects in order to find suitable mapping strategies from DDC to CLC while minimizing manual intervention.The findings have facilitated the establishment of DDC-CLC mapping

  8. Adaptive strategies of the visualization of electronic map

    Wang, Hong; Ai, Tinghua

    2006-10-01

    The visualization of electronic map should be dynamic not only in the way of representation but also in the content creation in real time. In on-demand mapping, the user's favorites to map content are the key factor. It means that the design of electronic map has to consider providing several candidate visualizations according to the user's context. To settle on-demand question, the adaptive visualization has been an active topic in the field of map design in recent years. Based on practical experiments, this paper tries to present some adaptive strategies on the visualization of electronic map. Firstly, a conceptual framework of adaptive visualization is proposed, what includes the parts of the context interface, the map behaviors triggering factors, the adaptive mechanism, hierarchy control, output of result map, and the evaluation methods. We consider three main factors associated with the adaptive visualization: (1). the user's interactive map behaviors, (2). the context of the surroundings where the electronic map system stays, (3). the user category under their knowledge and experiences. The map behaviors include the ZOOM OUT, ZOOM IN, PAN, QUERY, ROTATION, and etc, which will result in changes for the contents and structures of map. These changes relate to the aspects about Map Extent, Scale, Location, Quantity, Quality, Direction, Density, and etc. The surroundings of map reading include the screen size, color display or B/W display, brightness, weather, special light scenery, speed of data loading, display sets, sound, time, event, culture, language, and etc. The map design has to provide different strategies to satisfy the periphery environment changes. According to some egocentric conditions, i.e., Location, Moving Orientation, Speed of Motion, and Self Properties, this paper gives some practical illustrations and descriptive maps. The classification of map users considers their knowledge, experience and specialty. We divide users into different levels

  9. Digital soil mapping: strategy for data pre-processing

    2012-08-01

    Full Text Available The region of greatest variability on soil maps is along the edge of their polygons, causing disagreement among pedologists about the appropriate description of soil classes at these locations. The objective of this work was to propose a strategy for data pre-processing applied to digital soil mapping (DSM. Soil polygons on a training map were shrunk by 100 and 160 m. This strategy prevented the use of covariates located near the edge of the soil classes for the Decision Tree (DT models. Three DT models derived from eight predictive covariates, related to relief and organism factors sampled on the original polygons of a soil map and on polygons shrunk by 100 and 160 m were used to predict soil classes. The DT model derived from observations 160 m away from the edge of the polygons on the original map is less complex and has a better predictive performance.

  11. Integrating Terrain Maps Into a Reactive Navigation Strategy

    Howard, Ayanna; Werger, Barry; Seraji, Homayoun

    2006-01-01

    An improved method of processing information for autonomous navigation of a robotic vehicle across rough terrain involves the integration of terrain maps into a reactive navigation strategy. Somewhat more precisely, the method involves the incorporation, into navigation logic, of data equivalent to regional traversability maps. The terrain characteristic is mapped using a fuzzy-logic representation of the difficulty of traversing the terrain. The method is robust in that it integrates a global path-planning strategy with sensor-based regional and local navigation strategies to ensure a high probability of success in reaching a destination and avoiding obstacles along the way. The sensor-based strategies use cameras aboard the vehicle to observe the regional terrain, defined as the area of the terrain that covers the immediate vicinity near the vehicle to a specified distance a few meters away.

    Hasyim, Fuad; Subagio, Habib; Darmawan, Mulyanto

    2016-06-01

    A preparation of spatial planning documents require basic geospatial information and thematic accuracies. Recently these issues become important because spatial planning maps are impartial attachment of the regional act draft on spatial planning (PERDA). The needs of geospatial information in the preparation of spatial planning maps preparation can be divided into two major groups: (i). basic geospatial information (IGD), consist of of Indonesia Topographic maps (RBI), coastal and marine environmental maps (LPI), and geodetic control network and (ii). Thematic Geospatial Information (IGT). Currently, mostly local goverment in Indonesia have not finished their regulation draft on spatial planning due to some constrain including technical aspect. Some constrain in mapping of spatial planning are as follows: the availability of large scale ofbasic geospatial information, the availability of mapping guidelines, and human resources. Ideal conditions to be achieved for spatial planning maps are: (i) the availability of updated geospatial information in accordance with the scale needed for spatial planning maps, (ii) the guideline of mapping for spatial planning to support local government in completion their PERDA, and (iii) capacity building of local goverment human resources to completed spatial planning maps. The OMP strategies formulated to achieve these conditions are: (i) accelerating of IGD at scale of 1:50,000, 1: 25,000 and 1: 5,000, (ii) to accelerate mapping and integration of Thematic Geospatial Information (IGT) through stocktaking availability and mapping guidelines, (iii) the development of mapping guidelines and dissemination of spatial utilization and (iv) training of human resource on mapping technology.

  16. A genealogical map of the concept of habit.

    Barandiaran, Xabier E; Di Paolo, Ezequiel A

    2014-01-01

    The notion of information processing has dominated the study of the mind for over six decades. However, before the advent of cognitivism, one of the most prominent theoretical ideas was that of Habit. This is a concept with a rich and complex history, which is again starting to awaken interest, following recent embodied, enactive critiques of computationalist frameworks. We offer here a very brief history of the concept of habit in the form of a genealogical network-map. This serves to provide an overview of the richness of this notion and as a guide for further re-appraisal. We identify 77 thinkers and their influences, and group them into seven schools of thought. Two major trends can be distinguished. One is the associationist trend, starting with the work of Locke and Hume, developed by Hartley, Bain, and Mill to be later absorbed into behaviorism through pioneering animal psychologists (Morgan and Thorndike). This tradition conceived of habits atomistically and as automatisms (a conception later debunked by cognitivism). Another historical trend we have called organicism inherits the legacy of Aristotle and develops along German idealism, French spiritualism, pragmatism, and phenomenology. It feeds into the work of continental psychologists in the early 20th century, influencing important figures such as Merleau-Ponty, Piaget, and Gibson. But it has not yet been taken up by mainstream cognitive neuroscience and psychology. Habits, in this tradition, are seen as ecological, self-organizing structures that relate to a web of predispositions and plastic dependencies both in the agent and in the environment. In addition, they are not conceptualized in opposition to rational, volitional processes, but as transversing a continuum from reflective to embodied intentionality. These are properties that make habit a particularly attractive idea for embodied, enactive perspectives, which can now re-evaluate it in light of dynamical systems theory and complexity research

    Horn, M E; Horn, Martin Erik; Mikelskis, Helmut F.

    2004-01-01

    Due to its amazing three-dimensional effects, holography is a very motivating, yet very demanding subject for physics classes at the upper level in school. For this reason an instruction unit on holography that supplement holographic experiments with computer-supported work sessions and a simulation program was developed. The effects of the lessons on holography were determined by a pre-post-test design. In addition to videotaping the lessons, knowledge and motivational tests as well as student interviews, students were asked to prepare concept maps, which were used to track processes of model construction. The way this knowledge was applied largely depends on the students' understanding of models. In particular it was shown that the participating students' demonstrated capacity for distinguishing between the different models of light is of great importance. Only students with a developed capacity for distinguishing between models are able to reason in an problem-oriented manner. They recognize the limits of ...

  20. Mapping biological ideas: Concept maps as knowledge integration tools for evolution education

    Schwendimann, Beat Adrian

    Many students leave school with a fragmented understanding of biology that does not allow them to connect their ideas to their everyday lives (Wandersee, 1989; Mintzes, Wandersee, & Novak, 1998; Mintzes, Wandersee, & Novak, 2000a). Understanding evolution ideas is seen as central to building an integrated knowledge of biology (Blackwell, Powell, & Dukes, 2003; Thagard & Findlay, 2010). However, the theory of evolution has been found difficult to understand as it incorporates a wide range of ideas from different areas (Bahar et al., 1999; Tsui & Treagust, 2003) and multiple interacting levels (Wilensky & Resnick, 1999; Duncan & Reiser, 2007; Hmelo-Silver et al., 2007). Research suggests that learners can hold a rich repertoire of co-existing alternative ideas of evolution (for example, Bishop & Anderson, 1990; Demastes, Good, & Peebles, 1996; Evans, 2008), especially of human evolution (for example, Nelson, 1986; Sinatra et al., 2003; Poling & Evans, 2004). Evolution ideas are difficult to understand because they often contradict existing alternative ideas (Mayr, 1982; Wolpert, 1994; Evans, 2008). Research suggests that understanding human evolution is a key to evolution education (for example, Blackwell et al., 2003; Besterman & Baggott la Velle, 2007). This dissertation research investigates how different concept mapping forms embedded in a collaborative technology-enhanced learning environment can support students' integration of evolution ideas using case studies of human evolution. Knowledge Integration (KI) (Linn et al., 2000; Linn et al., 2004) is used as the operational framework to explore concept maps as knowledge integration tools to elicit, add, critically distinguish, group, connect, and sort out alternative evolution ideas. Concept maps are a form of node-link diagram for organizing and representing connections between ideas as a semantic network (Novak & Gowin, 1984). This dissertation research describes the iterative development of a novel biology

  5. A standardised, holistic framework for concept-map analysis combining topological attributes and global morphologies

    Stefan Yoshi Buhmann

    2015-03-01

    Full Text Available Motivated by the diverse uses of concept maps in teaching and educational research, we have developed a systematic approach to their structural analysis. The basis for our method is a unique topological normalisation procedure whereby a concept map is first stripped of its content and subsequently geometrically re-arranged into a standardised layout as a maximally balanced tree following set rules. This enables a quantitative analysis of the normalised maps to read off basic structural parameters: numbers of concepts and links, diameter, in- and ex-radius and degree sequence and subsequently calculate higher parameters: cross-linkage, balance and dimension. Using these parameters, we define characteristic global morphologies: ‘Disconnected’, ‘Imbalanced’, ‘Broad’, ‘Deep’ and ‘Interconnected’ in the normalised map structure. Our proposed systematic approach to concept-map analysis combining topological normalisation, determination of structural parameters and global morphological classification is a standardised, easily applicable and reliable framework for making the inherent structure of a concept map tangible. It overcomes some of the subjectivity inherent in analysing and interpreting maps in their original form while also avoiding the pitfalls of an atomistic analysis often accompanying quantitative concept-map analysis schemes. Our framework can be combined and cross-compared with a content analysis to obtain a coherent view of the two key elements of a concept map: structure and content. The informed structural analysis may form the starting point for interpreting the underlying knowledge structures and pedagogical meanings.

  14. Using concept mapping for assessing and promoting relational conceptual change in science

    Liu, Xiufeng

    2004-05-01

    In this article, we adopted the relational conceptual change as our theoretical framework to accommodate current views of conceptual change such as ontological beliefs, epistemological commitment, and social/affective contexts commonly mentioned in the literature. We used a specific concept mapping format and process - digraphs and digraphing - as an operational framework for assessing and promoting relational conceptual change. We wanted to find out how concept mapping can be used to account for relational conceptual change. We collected data from a Grade 12 chemistry class using collaborative computerized concept mapping on an ongoing basis during a unit of instruction. Analysis of progressive concept maps and interview transcripts of representative students and the teacher showed that ongoing and collaborative computerized concept mapping is able to account for student conceptual change in ontological, epistemological, and social/affective domains.

    Full Text Available A growing awareness exists of the possibilities of architectural research adopting working methods used by artists. Many artists have adapted ethnographic methodologies to map site specificity and issues related to community and sociospatial practices. This paper draws on related examples of art practice to formulate a specific research strategy: ethnographic intervention. Ethnographic intervention has three characteristics: (a ethnographic mapping of spatial practices on site, (b the possibility of a horizontal replication of the study, and (c an intervention protocol. We define ethnographic mapping as a critical process directed towards a specific cultural, social, or architectural situation. This involves re-presenting the situation through observing, documenting, videorecording, and photography. We explore the necessity of horizontal replication for producing reliable studies. Finally, we discuss the development of a multi-stage intervention protocol as a creative and flexible instrument, involving design and preparation, data collection, interpretation, and narration. Three case studies illustrate how this strategy has been conceived, applied, and developed at architectural sites. The article concludes with a discussion of the outcomes, usefulness, and possible applications of this strategy in other disciplines.

  20. Ontology-based concept map learning path reasoning system using SWRL rules

    Chu, K.-K.; Lee, C.-I. [National Univ. of Tainan, Taiwan (China). Dept. of Computer Science and Information Learning Technology

    2010-08-13

    Concept maps are graphical representations of knowledge. Concept mapping may reduce students' cognitive load and extend simple memory function. The purpose of this study was on the diagnosis of students' concept map learning abilities and the provision of personally constructive advice dependant on their learning path and progress. Ontology is a useful method with which to represent and store concept map information. Semantic web rule language (SWRL) rules are easy to understand and to use as specific reasoning services. This paper discussed the selection of grade 7 lakes and rivers curriculum for which to devise a concept map learning path reasoning service. The paper defined a concept map e-learning ontology and two SWRL semantic rules, and collected users' concept map learning path data to infer implicit knowledge and to recommend the next learning path for users. It was concluded that the designs devised in this study were feasible and advanced and the ontology kept the domain knowledge preserved. SWRL rules identified an abstraction model for inferred properties. Since they were separate systems, they did not interfere with each other, while ontology or SWRL rules were maintained, ensuring persistent system extensibility and robustness. 15 refs., 1 tab., 8 figs.

  1. A Study of Biomedical Concept Identification: MetaMap vs. People

    Pratt, Wanda; Yetisgen-Yildiz, Meliha

    2003-01-01

    Although huge amounts of unstructured text are available as a rich source of biomedical knowledge, to process this unstructured knowledge requires tools that identify concepts from free-form text. MetaMap is one tool that system developers in biomedicine have commonly used for such a task, but few have studied how well it accomplishes this task in general. In this paper, we report on a study that compares MetaMap’s performance against that of six people. Such studies are challenging because the task is inherently subjective and establishing consensus is difficult. Nonetheless, for those concepts that subjects generally agreed on, MetaMap was able to identify most concepts, if they were represented in the UMLS. However, MetaMap identified many other concepts that people did not. We also report on our analysis of the types of failures that MetaMap exhibited as well as trends in the way people chose to identify concepts. PMID:14728229

    2010-04-01

    Full Text Available Higher education deals with complex knowledge and university teaching should focus on conceptual understanding. Adequate knowledge structures are essential and active knowledge construction should be supported for meaningful learning. But traditional lectures mostly are structured by slides which may misleadingly cause linear representations of knowledge. In this study, a framework for digital concept maps was developed to complement lectures in human biology. The course was aimed at student science teachers at the undergraduate level. The work is based on theoretical research on computer-supported learning, on knowledge structures perspectives within learning environments as well as on self-determination theory. Each session was supplemented by a digital, multimedia-enriched concept map. After each single lecture, students had free access to the concept maps to reinforce the latest topics. The objective of the study was to examine if the use of complementary concept maps (i influences achievement and (ii if motivational variables influence the use of the concept maps. In both cases, influences of computer-user self-efficacy were expected (iii. The students’ (N = 171 concept map use was logged, achievement was tested and motivational variables were surveyed (e.g. interest/ enjoyment, perceived competence, effort/ importance, value/usefulness. The logfile-data allowed distinguishing learners according to their concept map use. Results reveal the benefit of additional concept maps for achievement, positive motivational aspects and computer-user self-efficacy as mediating factors showed some influence. The emphasize of further research should be on students’ active engagement in structuring their individual learning by constructing concept maps themselves, especially in science education courses.

  5. A new strategy for developing Vs30 maps

    Wald, David J.; McWhirter, Leslie; Thompson, Eric; Hering, Amanda S.

    2011-01-01

    Despite obvious limitations as a proxy for site amplification, the use of time-averaged shear-wave velocity over the top 30m (Vs30) is useful and widely practiced, most notably through its use as an explanatory variable in ground motion prediction equations (and thus hazard maps and ShakeMaps, among other applications). Local, regional, and global Vs30 maps thus have diverse and fundamental uses in earthquake and engineering seismology. As such, we are developing an improved strategy for producing Vs30 maps given the common observational constraints available in any region for various spatial scales. We investigate a hierarchical approach to mapping Vs30, where the baseline model is derived from topographic slope because it is available globally, but geological maps and Vs30 observations contribute, where available. Using the abundant measured Vs30 values in Taiwan as an example, we analyze Vs30 versus slope per geologic unit and observe minor trends that indicate potential interaction of geologic and slope terms. We then regress Vs30 for the geologic Vs30 medians, topographic-slope, and cross-term coefficients for a hybrid model. The residuals of this hybrid model still exhibit a strong spatial correlation structure, so we use the kriging-with-a-trend method (the trend is the hybrid model) to further refine the Vs30 map so as to honor the Vs30 observations. Unlike the geology or slope models alone, this strategytakes advantage of the predictive capabilities of the two models, yet effectively defaults to ordinary kriging in the vicinity of the observed data, thereby achieving consistency with the observed data.

  6. Radon mapping in Austria. New strategies and first results

    In Austria the set up of radon maps is required already since 1992 in the recommendation of the radiation protection commission and stated in the radiation protection law since 2004. In the framework of the Austrian National Radon Project (OENRAP) indoor radon measurements were carried out in about 9000 dwellings from 1992 to 2002, a radon potential was calculated for all municipalities and displayed in a radon potential map. This map is basis for decisions e.g. for preventive measures. According to the new European basic safety standards (EU-BSS) member states shall identify ''radon areas'', relevant e.g. for mandatory radon measurements at work places. The identification of such areas will impact several (legal) decisions and future measures. In course of the implementation of the EU-BSS the radon map of Austria should be improved and optimized for its purpose. As a first step indoor radon measurements were carried out in dwellings in municipalities detected to be ''outliers'' compared to neighboring municipalities. In addition a new indoor radon survey was designed and started, funded by the BMLFUW, with radon measurements in dwellings of members of the voluntary fire brigades, selected by defined criteria. As a pilot study measurements in about 6500 dwellings were carried out in Upper Austria from June 2014 to February 2015. Based on the results of the pilot study and an international radon mapping workshop held in Vienna in January 2015 possible methods for radon mapping in Austria will be tested and discussed. In this contribution the strategies, methods, first results and findings on the way to a new Austrian radon map will be presented.

  7. Concept, strategy and realization of lectin-based glycan profiling.

    Hirabayashi, Jun

    2008-08-01

    Lectins are a diverse group of carbohydrate-binding proteins. Each lectin has its own specificity profile. It is believed that lectins exist in all living organisms that produce glycans. From a practical viewpoint, lectins have been used extensively in biochemical fields including proteomics due to their usefulness as detection and enrichment tools for specific glycans. Nevertheless, they have often been underestimated as probes, especially compared with antibodies, because of their low affinity and broad specificity. However, together with the concept of glycomics, such properties of lectins are now considered to be suitable for the task of 'profiling' in order to cover a wider range of ligands. Recently there has been rapid movement in the field of proteomics aimed at the investigation of glycan-related biomarkers. This is partly because of limitations of the present approach of simply following changes in protein-level expression, without paying sufficient attention to the fact and effects of glycosylation. The trend is reflected in the frequent use of lectins in the contexts of glycoprotein enrichment and glycan profiling. However, there are many aspects to be considered in using lectins, which differ considerably from antibodies. In this article, the author, as a developer of two unique methodologies, frontal affinity chromatography (FAC) and the lectin microarray, describes critical points concerning the use of lectins, together with the concept, strategy and means to achieve advances in these emerging glycan profiling technologies.

  8. Discrimination of mixed quantum states. Reversible maps and unambiguous strategies

    The discrimination of two mixed quantum states is a fundamental task in quantum state estimation and quantum information theory. In quantum state discrimination a quantum system is assumed to be in one of two possible - in general mixed - non-orthogonal quantum states. The discrimination then consists of a measurement strategy that allows to decide in which state the system was before the measurement. In unambiguous state discrimination the aim is to make this decision without errors, but it is allowed to give an inconclusive answer. Especially interesting are measurement strategies that minimize the probability of an inconclusive answer. A starting point for the analysis of this optimization problem was a result by Eldar et al. [Phys. Rev. A 69, 062318 (2004)], which provides non-operational necessary and sufficient conditions for a given measurement strategy to be optimal. These conditions are reconsidered and simplified in such a way that they become operational. The simplified conditions are the basis for further central results: It is shown that the optimal measurement strategy is unique, a statement that is e.g. of importance for the complexity analysis of optimal measurement devices. The optimal measurement strategy is derived for the case, where one of the possible input states has at most rank two, which was an open problem for many years. Furthermore, using the optimality criterion it is shown that there always exists a threshold probability for each state, such that below this probability it is optimal to exclude this state from the discrimination strategy. If the two states subject to discrimination can be brought to a diagonal structure with (2 x 2)-dimensional blocks, then the unambiguous discrimination of these states can be reduced to the unambiguous discrimination of pure states. A criterion is presented that allows to identify the presence of such a structure for two self-adjoint operators. This criterion consists of the evaluation of three

  19. Building an organized knowledge base: Concept mapping and achievement in secondary school physics

    Pankratius, William J.

    Direct teaching of problem-solving methods to high school physics students met with little success. Expert problem solving depended upon an organized knowledge base. Concept mapping was found to be a key to organizing an effective knowledge base. The investigation of the effect of the degree of concept mapping on achievement was the purpose of this study. Six intact high school physics classes, taught by this investigator, took part in the study. Two classes were control groups and received standard instruction. Four classes received six weeks of concept-mapping instruction prior to the unit under study. Two of these four classes were the low-level treatment group and were required to submit concept maps at the conclusion of the instruction. The other two classes were the high-level treatment group and were required to submit concept maps at the beginning and at the conclusion of the unit under study. One class from each treatment group took a pretest prior to instruction. An analysis of the posttest results revealed no pretest sensitization. A one-way analysis of covariance indicated a significant main effect for the treatment level at the p physics students) mapping concepts prior to, during, and subsequent to instruction led to greater achievement as measured by posttest scores.

    Full Text Available This paper contains reflections and results of a research that aimed to apply and analyze the use of concept maps in Higher Education as an indicator of significant learning concerning derivative as mathematical object with students that finished Differential and Integral Calculus. This is a qualitative approach, situated in the area of mathematics education, based on Ausubel's Theory of Meaningful Learning and on technique of Novak's Concept Mapping. As data acquisition instruments, use of classroom observations, questionnaire, brainstorming and digital conceptual mapping, made by an undergraduate physics course. To analyze we defined four aspects to be observed in the maps constructed by students: (i validity of propositions formed with concepts, (ii hierarchization, (iii cross-links between the propositions, and (vi the presence of applications. The identification of these elements, taken as reference to analyze the maps, allowed the collection of information about how each student has structured and correlated the set of concepts learned on the derivative of a function along their course. Based on the results, we have identified in the digital conceptual maps effective tools to evaluate the students in terms of meaningful learning about specific contents of Differential and Integral Calculus by the hierarchy of concepts, progressive differentiation and integrative reconciliation as defined in the Theory of Meaningful Learning.

  12. A Study of Concept Mapping as an Instructional Intervention in an Undergraduate General Chemistry Calorimetry Laboratory

    Stroud, Mary W.

    This investigation, rooted in both chemistry and education, considers outcomes occurring in a small-scale study in which concept mapping was used as an instructional intervention in an undergraduate calorimetry laboratory. A quasi-experimental, multiple-methods approach was employed since the research questions posed in this study warranted the use of both qualitative and quantitative perspectives and evaluations. For the intervention group of students, a convenience sample, post-lab concept maps, written discussions, quiz responses and learning surveys were characterized and evaluated. Archived quiz responses for non-intervention students were also analyzed for comparison. Students uniquely constructed individual concept maps containing incorrect, conceptually correct and "scientifically thin" calorimetry characterizations. Students more greatly emphasized mathematical relationships and equations utilized during the calorimetry experiment; the meaning of calorimetry concepts was demonstrated to a lesser extent.

  13. The topographic grain concept in DEM-based geomorphometric mapping

    Józsa, Edina

    2016-04-01

    A common drawback of geomorphological analyses based on digital elevation datasets is the definition of search window size for the derivation of morphometric variables. The fixed-size neighbourhood determines the scale of the analysis and mapping, which can lead to the generalization of smaller surface details or the elimination of larger landform elements. The methods of DEM-based geomorphometric mapping are constantly developing into the direction of multi-scale landform delineation, but the optimal threshold for search window size is still a limiting factor. A possible way to determine the suitable value for the parameter is to consider the topographic grain principle (Wood, W. F. - Snell, J. B. 1960, Pike, R. J. et al. 1989). The calculation is implemented as a bash shell script for GRASS GIS to determine the optimal threshold for the r.geomorphon module. The approach relies on the potential of the topographic grain to detect the characteristic local ridgeline-to-channel spacing. By calculating the relative relief values with nested neighbourhood matrices it is possible to define a break-point where the increase rate of local relief encountered by the sample is significantly reducing. The geomorphons approach (Jasiewicz, J. - Stepinski, T. F. 2013) is a cell-based DEM classification method for the identification of landform elements at a broad range of scales by using line-of-sight technique. The landforms larger than the maximum lookup distance are broken down to smaller elements therefore the threshold needs to be set for a relatively large value. On the contrary, the computational requirements and the size of the study sites determine the upper limit for the value. Therefore the aim was to create a tool that would help to determine the optimal parameter for r.geomorphon tool. As a result it would be possible to produce more objective and consistent maps with achieving the full efficiency of this mapping technique. For the thorough analysis on the

  16. Concepts and strategies for management of nuclear wastes

    Three modes of reactor strategies are chosen and discussed; (1) Once-through type light water reactor, (2) U-Pu cycle light water reactor, and (3) U-Pu cycle fast breeder reactor. The arising of wastes in each mode of nuclear fuel cycle is first estimated for unit nuclear power generation of 1 GWe.year and the amount of wastes to be managed in each year is then calculated. Assuming the 2nd and the 3rd reprocessing plants are not operative, the decrease of waste arising is also estimated, which, nevertheless, claims the need for spent fuel storage pools. In addition, the arisings of decommissioning wastes are evaluated to identify their effect on waste management. Based on above fact, a generic logic of waste management is brought about, placing major emphasis on volume reduction, barrier- and decay-effects. According to the characteristics, the wastes arisen at each stage of nuclear fuel cycle can be categorized into (1) extremely low-level waste, (2) low- and intermediate-level waste, (3) alpha-waste and (4) high-level waste, and the suitable isolation periods for the specified categories can be set by the aid of hazard index, suggesting that the disposal options may possibly be selected. The waste disposal gives environmental impacts through dispersion and migration of contained nuclides into biosphere; the dispersion and migration paths are investigated and a mathematical expression to evaluate the impacts as dose commitment is presented. A multi-barrier concept is proposed since combined artificial and natural barriers have possibility of lengthening the migration path to enable safe disposal. Finally, items of research/development in waste management are represented from the viewpoints of (1) establishment of management system, (2) safety assessment covering verification of technology and system, and (3) regulation, giving recommendations for national policy making as well as for international co-operation.

  3. The articulation of integration of clinical and basic sciences in concept maps: differences between experienced and resident groups.

    Vink, Sylvia; van Tartwijk, Jan; Verloop, Nico; Gosselink, Manon; Driessen, Erik; Bolk, Jan

    2016-08-01

    To determine the content of integrated curricula, clinical concepts and the underlying basic science concepts need to be made explicit. Preconstructed concept maps are recommended for this purpose. They are mainly constructed by experts. However, concept maps constructed by residents are hypothesized to be less complex, to reveal more tacit basic science concepts and these basic science concepts are expected to be used for the organization of the maps. These hypotheses are derived from studies about knowledge development of individuals. However, integrated curricula require a high degree of cooperation between clinicians and basic scientists. This study examined whether there are consistent variations regarding the articulation of integration when groups of experienced clinicians and basic scientists and groups of residents and basic scientists-in-training construct concept maps. Seven groups of three clinicians and basic scientists on experienced level and seven such groups on resident level constructed concept maps illuminating clinical problems. They were guided by instructions that focused them on articulation of integration. The concept maps were analysed by features that described integration. Descriptive statistics showed consistent variations between the two expertise levels. The concept maps of the resident groups exceeded those of the experienced groups in articulated integration. First, they used significantly more links between clinical and basic science concepts. Second, these links connected basic science concepts with a greater variety of clinical concepts than the experienced groups. Third, although residents did not use significantly more basic science concepts, they used them significantly more frequent to organize the clinical concepts. The conclusion was drawn that not all hypotheses could be confirmed and that the resident concept maps were more elaborate than expected. This article discusses the implications for the role that residents and

  5. Combining Concept Maps with Quantitative Data and Writing Assignments to Foster Student Engagement

    Bank, C.; Eckert, T.

    2008-12-01

    Introductory geoscience is in a unique position to provide students with readily available data, problems that require careful analysis, and issues affecting their communities. Teaching introductory geoscience allows the instructors to package the developing of skills (quantitative numeracy, critical thinking, presenting) with the learning of new concepts. We have introduced in a large distribution course several assignments which combine concept maps with the analysis of quantitative data and short writing requirements. The aim of such assignments is to allow students to gain insight into scientific thinking, to challenge their pre-existing conceptions, and to achieve a deeper understanding of topics. It also provides us with the opportunity to experiment with novel assessment tools. In some cases, we have attempted to proof the effectiveness of such assessments. For example, a preliminary comparison of student performance on final exams indicates a correlation between marks gained on a concept map and those achieved on a short essay. This correlation implies that concept maps can be valid assessment tools. Other assignments, for example the creation of podcasts by small groups of students, provide for anecdotal evidence that students learn new concepts better because they need to reflect on them more carefully in order to present the assigned material.

  7. A Student-centred Approach: Assessing the Changes in Prospective Science Teachers' Conceptual Understanding by Concept Mapping in a General Chemistry Laboratory

    Kaya, Osman Nafiz

    2008-01-01

    Although researchers in higher education propose alternatives to traditional approaches to assessment, traditional methods are commonly used in college or university science courses. The purpose of this study was to explore the feasibility and validity of Prospective Science Teachers’ (PSTs) concept maps as authentic assessment tools in a student-centred approach to describe the changes in the conceptual understanding of the PSTs in general chemistry laboratory investigations. After the PSTs ( n = 47) decided on important issues, such as who would assess their concept maps and what scoring strategy and criteria would be used, they practiced assessing their own and peers’ concept maps during the first five laboratory investigations. They subsequently constructed and assessed pre- and post-laboratory concept maps in a student-centred approach consisting of self, peer, and instructor assessments for the five remaining laboratory investigations. The results of the study showed using pre- and post-laboratory concept maps as authentic assessment tools in a student-centred approach was valid and reliable for describing the conceptual understanding of the PSTs in a university general chemistry laboratory course. The results of individual interviews indicated most PSTs had positive views of their assessment practices in the laboratory course. This study also provides pedagogical implications for the training of science teachers.

    Full Text Available This work proposes to detect and correct concept errors (EECC to obtain Meaningful Learning (AS. The Conductive Model does not respond to the demand of meaningful learning that implies gathering thought, feeling and action to lead students up to both compromise and responsibility. In order to respond to the society competition about knowledge and information it is necessary to change the way of teaching and learning (from conductive model to constructive model. In this context it is important not only to learn meaningfully but also to create knowledge so as to developed dissertive, creative and critical thought, and the EECC are and obstacle to cope with this. This study tries to get ride of EECC in order to get meaningful learning. For this, it is essential to elaborate a Teaching Module (MI. This teaching Module implies the treatment of concept errors by a teacher able to change the dynamic of the group in the classroom.

    1999-11-01

    The purpose of this study was to determine the effect of using concept maps or dialogue journals on bilingual students' conceptual understanding in science. Three fourth grade classes, which included 60 students, using the Science and Technology for Children, Plant Growth and Development unit participated in the study. The vocabulary knowledge and conceptual understanding of bilingual and native English students in three treatment groups were compared. The study was conducted over a three month period. The three treatment groups consisted of (1) a control group using only the Science and Technology for Children, Plant Growth and Development unit, (2) the concept map treatment group, and (3) the dialogue journal treatment group. Student achievement was measured using a pretest and a posttest. Significant differences in the pretest and posttest scores were found for all three treatment groups. The concept map treatment group scored significantly higher than the dialogue journal and control groups on the posttest. The use of concept maps was found to be highly effective for both native English and bilingual students.

  6. Complexity Results and Approximation Strategies for MAP Explanations

    Darwiche, A; 10.1613/jair.1236

    2011-01-01

    MAP is the problem of finding a most probable instantiation of a set of variables given evidence. MAP has always been perceived to be significantly harder than the related problems of computing the probability of a variable instantiation Pr, or the problem of computing the most probable explanation (MPE). This paper investigates the complexity of MAP in Bayesian networks. Specifically, we show that MAP is complete for NP^PP and provide further negative complexity results for algorithms based on variable elimination. We also show that MAP remains hard even when MPE and Pr become easy. For example, we show that MAP is NP-complete when the networks are restricted to polytrees, and even then can not be effectively approximated. Given the difficulty of computing MAP exactly, and the difficulty of approximating MAP while providing useful guarantees on the resulting approximation, we investigate best effort approximations. We introduce a generic MAP approximation framework. We provide two instantiations of the frame...

  7. Concept Mapping: A Dynamic, Individualized and Qualitative Method for Eliciting Meaning.

    Wilson, Jessie; Mandich, Angie; Magalhães, Lilian

    2016-07-01

    The purpose of this theoretical article is to explore the use of concept mapping as a qualitative research method that is represented as a form of multimodal communication. This framework strives to move mapping beyond quantitative analysis by inserting art and humanness into the process. This proposed framework provides a means to highlight the ways in which people learn, understand, and interpret the world around them. Three categories for understanding have been identified by the authors to help individuals create, interpret, and understand qualitative concept maps. These categories include the following: Voice: Tri-directional Voice and Mutual Absorption; Detail in the Parts & Recognition of the Whole: Uniqueness, Aesthetic Distance and Emplacement; and Sensory Experience: Intellectual + Emotional Investment and Humanness. Each of these categories is interconnected, and informs each other in a dialectical way, therefore creating a piece of visual data with which the participant, researcher and audience can interact.

  8. An Alternative to Mapping a Word onto a Concept in Language Acquisition: Pragmatic Frames

    Rohlfing, Katharina J.; Wrede, Britta; Vollmer, Anna-Lisa; Oudeyer, Pierre-Yves

    2016-01-01

    The classic mapping metaphor posits that children learn a word by mapping it onto a concept of an object or event. However, we believe that a mapping metaphor cannot account for word learning, because even though children focus attention on objects, they do not necessarily remember the connection between the word and the referent unless it is framed pragmatically, that is, within a task. Our theoretical paper proposes an alternative mechanism for word learning. Our main premise is that word learning occurs as children accomplish a goal in cooperation with a partner. We follow Bruner’s (1983) idea and further specify pragmatic frames as the learning units that drive language acquisition and cognitive development. These units consist of a sequence of actions and verbal behaviors that are co-constructed with a partner to achieve a joint goal. We elaborate on this alternative, offer some initial parametrizations of the concept, and embed it in current language learning approaches. PMID:27148105

  12. ADDRESSING WATER FOOTPRINT CONCEPT: A DEMONSTRABLE STRATEGY FOR PAPERMAKING INDUSTRY

    Jing Shen,

    2012-05-01

    Full Text Available Since the introduction of the water footprint concept in 2002, in the context of humankind’s ever-increasing awareness of the valuable global freshwater resources, it has received more and more attention. The application of this relatively new concept has been expected to provide ecological and environmental benefits. For the water-intensive papermaking industry, it seems that water footprint needs to be addressed. The water footprint of cellulosic paper can be divided into three components, including its green water footprint, blue water footprint, and grey water footprint, which may be accounted for by considering the individual contributions of wood or non-wood materials, pulp production processes, effluent discharge to the receiving water bodies, process chemicals and additives, energy consumption, etc. In the literature, the accounting of water footprint during the whole production chain of cellulosic paper is already available, and relevant research findings can provide useful insights into the application of the concept; however, further development of the accounting methodologies is much needed, so that the quantitative and qualitative evaluation of water footprint can be internationally recognized, certified, and standardized. Although there are ongoing or upcoming debates and challenges associated with the concept, its application to papermaking industry may be expected to provide various encouraging possibilities and impacts.

  14. A metacognitive tool: Theoretical and operational analysis of skills exercised in structured concept maps

    Marie-Pierre Chevron

    2014-01-01

    Full Text Available Developing meaningful learning is not only difficult to achieve but also time consuming, because it requires a large number of different skills to develop and master. Many studies have shown that organizing knowledge in concept maps helps teachers and students to develop such a meaningful learning (Nesbit, J.C., Adescope, O.O., 2006. Learning with concept and knowledge maps: a meta-analysis. Rev. Educ. Res. 76:3, 413–446. Based on the work of Tyler (Tyler, R.W., 1950. Basic principles of Curriculum and Instruction. University of Chicago Press, Chicago, IL and Anderson (Anderson, L.W., Krathwohl, D.R., Airasian, P.W., Cruikshank, K.A., Mayer, R.E., Pintrich, P.R., Raths, J., Wittrock, M.C., 2001. A Taxonomy for Learning, Teaching, and Assessing: A revision of Bloom׳s Taxonomy of Educational Objectives. Longman, New York, this study proposes to characterize and to organize precisely, rigorously, and operationally in a two-dimensional matrix, the skills exercised during the elaboration of concept maps, here referred to as context-dependent and hierarchically structured concept maps (sCM. These skills correspond to those actually needed in transfer of knowledge, and the matrix could be used as an instructional tool to assist learners and teachers in this transfer. In addition it allows them to pay attention to the cognitive processes and types of knowledge involved during sCM elaboration. Making explicit the taxonomic levels of cognitive efforts implemented while organizing knowledge in a concept map could constitute a useful metacognitive tool to focus the teachers and learners׳ attention and efforts towards achieving higher-order thinking skills and meaningful learning.

Some of the ideas from Ausubel’s (1963; 1968 assimilation theory of cognitive learning that served as a foundation for concept mapping are presented, including the important role that assimilating new concepts and propositions into a learner’s existing cognitive framework plays in meaning making. Epistemological foundations are also presented including the idea that creative production of new knowledge can be seen as a very high level of meaningful learning, and concept mapping can facilitate the process. The wide range of tools available in free CmapTools software and some applications are illustrated, including application for facilitating meaningful learning, better curriculum development, capturing and archiving tacit and explicit expert knowledge, and enhancing creative production. Using CmapTools, WWW resources, and other digital resources provide for a powerful New Model for Education leading to the creation of individual knowledge portfolios that can document significant learning and serve as a foundation for future related learning. CmapTools also provides extensive support for collaboration, publishing and sharing of knowledge models.

  6. Application of concept mapping principles to managing steam generator knowledge at the CNSC

    The Canadian Nuclear Safety Commission (CNSC) oversee proper regulation required for the operations of more than 180 commercial steam generators housed in Canadian nuclear power plants. The number of inspection reports and other technical reports concerning the operation of these units result in a significant amount of information over time. Consequently the method to access the information easily and in a timely manner can require improvement. The Steam Generator Knowledge Management project was developed as a mode to efficiently manage and integrate all knowledge and resources relevant to steam generators found in a variety of sources used by the CNSC to conduct assessments. From a regulatory point of view, the tool was created to facilitate the assessment process of inspection reports as well as licence renewal requests proposed by licensees. The project provides a concise and logical interface between the user and diverse resources involved in performing regulatory activities. These include links to standards, CNSC license documents, operating experience from other regulators and licensees, electronic banks of research documents, journal articles, studies, and previously submitted licensee reports and responses. The concept of knowledge mapping was applied using Excel and Access software in order to achieve these goals. This software uses an approach toward associating related concepts, which is modeled after the way in which the human brain is believed to acquire and assimilate new knowledge into its existing framework. This results in a network that is intuitively set up and conducive to the accumulation of further knowledge and resources. This paper provides an abridged account of the theory governing concept mapping, not to mention its origins and the impact generated by its application in an organizational milieu. In addition, an indication of those successful integrations of concept mapping into large organizations, both commercial and scientific, is

    2015-03-01

    Full Text Available While the utility of concept mapping has been widely reported in primary and secondary educational contexts, its application in the health sciences in higher education has been less frequently noted. Two case studies of the application of concept mapping in undergraduate and postgraduate health sciences are detailed in this paper. The case in undergraduate dental education examines the role of concept mapping in supporting problem-based learning and explores how explicit induction into the principles and practices of CM has add-on benefits to learning in an inquiry-based curriculum. The case in postgraduate medical education describes the utility of concept mapping in an online inquiry-based module design. Specific attention is given to applications of CMapTools™ software to support the implementation of Novakian concept mapping in both inquiry-based curricular contexts.

  12. Developing a Robust Strategy Map in Balanced Scorecard Model Using Scenario Planning

    Mostafa Jafari

    2015-01-01

    Full Text Available The key to successful strategy implementation in an organization is for people in the organization to understand it, which requires the establishment of complicated but vital processes whereby the intangible assets are converted into tangible outputs. In this regard, a strategy map is a useful tool that helps execute this difficult task. However, such maps are typically developed based on ambiguous cause-effect relationships that result from the extrapolation of past data and flawed links with possible futures. However, if the strategy map is a mere reflection of the status quo but not future conditions and does not embrace real-world uncertainties, it will endanger the organization since it posits that the current situation will continue. In order to compensate for this deficiency, the environmental scenarios affecting an organization were identified in the present study. Then the strategy map was developed in the form of a scenario-based balanced scorecard. Besides, the effect of environmental changes on the components of the strategy map was investigated using the strategy maps illustrated over time together with the corresponding cash flow vectors. Subsequently, a method was proposed to calculate the degree of robustness of every component of the strategy map for the contingency of every scenario. Finally, the results were applied to a post office.

    2016-03-01

    Full Text Available Concept mapping is a method of graphical learning that can be beneficial as a study method for concept linking and organization. Concept maps, which provide an elegant, easily understood representation of an expert’s domain knowledge, are tools for organizing and representing knowledge. These tools have been used in educational environments to better connect the relationships among theory and practice as well as among other concepts covered in a course. They also help the learners build relationships between previous knowledge and newly introduced concepts, encouraging meaningful learning rather than rote learning. The overall interactions among hardware, computer basics, computer functions and etc., used to be simple and transparent enough for understanding computer systems. Nevertheless the modern computer technologies have become increasingly more complex which makes it very difficult to understand the whole system of the computers. This study is an analysis of the contribution made by concept maps to a Computer Architecture and Organization course (CAO. For a period of one semester, students were asked to prepare concept maps that they were later allowed to use when revising for their final exam. The students’ success in the exam was then evaluated and their attitudes towards the course, the concept maps and the questions on them were surveyed and analyzed. The results lead to the conclusion that not only did concept maps make a positive contribution to the students’ overall success during the course, they also helped with their exam preparation.

    Full Text Available Background Development of practical skills in the field of nursing education has remained a serious and considerable challenge in nursing education. Moreover, newly graduated nurses may have weak practical skills, which can be a threat to patients’ safety. Objectives The present study was conducted to compare the effect of concept mapping and conventional methods on nursing students’ practical skills. Patients and Methods This quasi-experimental study was conducted on 70 nursing students randomly assigned into two groups of 35 people. The intervention group was taught through concept mapping method, while the control group was taught using conventional method. A two-part instrument was used including a demographic information form and a checklist for direct observation of procedural skills. Descriptive statistics, chi-square, independent samples t-tests and paired t-test were used to analyze data. Results Before education, no significant differences were observed between the two groups in the three skills of cleaning (P = 0.251, injection (P = 0.185 and sterilizing (P = 0.568. The students mean scores were significantly increased after the education and the difference between pre and post intervention of students mean scores were significant in the both groups (P < 0.001. However, after education, in all three skills the mean scores of the intervention group were significantly higher than the control group (P < 0.001. Conclusions Concept mapping was superior to conventional skill teaching methods. It is suggested to use concept mapping in teaching practical courses such as fundamentals of nursing.

  3. Radiation treatment of brain tumors: Concepts and strategies

    Marks, J.E. (Loyola Univ. of Chicago Stritch School of Medicine, Maywood, IL (USA))

    1989-01-01

    Ionizing radiation has demonstrated clinical value for a multitude of CNS tumors. Application of the different physical modalities available has made it possible for the radiotherapist to concentrate the radiation in the region of the tumor with relative sparing of the surrounding normal tissues. Correlation of radiation dose with effect on cranial soft tissues, normal brain, and tumor has shown increasing effect with increasing dose. By using different physical modalities to alter the distribution of radiation dose, it is possible to increase the dose to the tumor and reduce the dose to the normal tissues. Alteration of the volume irradiated and the dose delivered to cranial soft tissues, normal brain, and tumor are strategies that have been effective in improving survival and decreasing complications. The quest for therapeutic gain using hyperbaric oxygen, neutrons, radiation sensitizers, chemotherapeutic agents, and BNCT has met with limited success. Both neoplastic and normal cells are affected simultaneously by all modalities of treatment, including ionizing radiation. Consequently, one is unable to totally depopulate a tumor without irreversibly damaging the normal tissues. In the case of radiation, it is the brain that limits delivery of curative doses, and in the case of chemical additives, it is other organ systems, such as bone marrow, liver, lung, kidneys, and peripheral nerves. Thus, the major obstacle in the treatment of malignant gliomas is our inability to preferentially affect the tumor with the modalities available. Until it is possible to directly target the neoplastic cell without affecting so many of the adjacent normal cells, the quest for therapeutic gain will go unrealized.72 references.

  4. Teaching Plate Tectonic Concepts using GeoMapApp Learning Activities

    Goodwillie, A. M.; Kluge, S.

    2012-12-01

    GeoMapApp Learning Activities ( http://serc.carleton.edu/geomapapp/collection.html ) can help educators to expose undergraduate students to a range of earth science concepts using high-quality data sets in an easy-to-use map-based interface called GeoMapApp. GeoMapApp Learning Activities require students to interact with and analyse research-quality geoscience data as a means to explore and enhance their understanding of underlying content and concepts. Each activity is freely available through the SERC-Carleton web site and offers step-by-step student instructions and answer sheets. Also provided are annotated educator versions of the worksheets that include teaching tips, additional content and suggestions for further work. The activities can be used "off-the-shelf". Or, since the educator may require flexibility to tailor the activities, the documents are provided in Word format for easy modification. Examples of activities include one on the concept of seafloor spreading that requires students to analyse global seafloor crustal age data to calculate spreading rates in different ocean basins. Another activity has students explore hot spots using radiometric age dating of rocks along the Hawaiian-Emperor seamount chain. A third focusses upon the interactive use of contours and profiles to help students visualise 3-D topography on 2-D computer screens. A fourth activity provides a study of mass wasting as revealed through geomorphological evidence. The step-by-step instructions and guided inquiry approach reduce the need for teacher intervention whilst boosting the time that students can spend on productive exploration and learning. The activities can be used, for example, in a classroom lab with the educator present and as self-paced assignments in an out-of-class setting. GeoMapApp Learning Activities are funded through the NSF GeoEd program and are aimed at students in the introductory undergraduate, community college and high school levels. The activities are

  5. A Balanced Scorecard With Strategy Map: Measuring the Value of a Nursing Sabbatical.

    Embree, Jennifer L; Swenty, Constance F; Schaar, Gina

    2015-01-01

    Seasoned nurses frequently resign from their positions due to burnout. An innovative idea that could support nurse retention is nurse sabbaticals. Balanced scorecards with strategy maps can display financial benefit, positive customer experience, and operational and human capital development required to initiate and sustain a professional nurse sabbatical. A balanced scorecard with strategy map is an effective tool that demonstrates connection between the organizational mission and the outcomes of a nurse sabbatical program. PMID:25764278

  6. Constructing a strategy map for banking institutions with key performance indicators of the balanced scorecard.

    Wu, Hung-Yi

    2012-08-01

    This study presents a structural evaluation methodology to link key performance indicators (KPIs) into a strategy map of the balanced scorecard (BSC) for banking institutions. Corresponding with the four BSC perspectives (finance, customer, internal business process, and learning and growth), the most important evaluation indicators of banking performance are synthesized from the relevant literature and screened by a committee of experts. The Decision Making Trial and Evaluation Laboratory (DEMATEL) method, a multiple criteria analysis tool, is then employed to determine the causal relationships between the KPIs, to identify the critical central and influential factors, and to establish a visualized strategy map with logical links to improve banking performance. An empirical application is provided as an example. According to the expert evaluations, the three most essential KPIs for banking performance are customer satisfaction, sales performance, and customer retention rate. The DEMATEL results demonstrate a clear road map to assist management in prioritizing the performance indicators and in focusing attention on the strategy-related activities of the crucial indicators. According to the constructed strategy map, management could better invest limited resources in the areas that need improvement most. Although these strategy maps of the BSC are not universal, the research results show that the presented approach is an objective and feasible way to construct strategy maps more justifiably. The proposed framework can be applicable to institutions in other industries as well. PMID:22410163

  9. An optimal strategy for functional mapping of dynamic trait loci.

    Jin, Tianbo; Li, Jiahan; Guo, Ying; Zhou, Xiaojing; Yang, Runqing; Wu, Rongling

    2010-02-01

    As an emerging powerful approach for mapping quantitative trait loci (QTLs) responsible for dynamic traits, functional mapping models the time-dependent mean vector with biologically meaningful equations and are likely to generate biologically relevant and interpretable results. Given the autocorrelation nature of a dynamic trait, functional mapping needs the implementation of the models for the structure of the covariance matrix. In this article, we have provided a comprehensive set of approaches for modelling the covariance structure and incorporated each of these approaches into the framework of functional mapping. The Bayesian information criterion (BIC) values are used as a model selection criterion to choose the optimal combination of the submodels for the mean vector and covariance structure. In an example for leaf age growth from a rice molecular genetic project, the best submodel combination was found between the Gaussian model for the correlation structure, power equation of order 1 for the variance and the power curve for the mean vector. Under this combination, several significant QTLs for leaf age growth trajectories were detected on different chromosomes. Our model can be well used to study the genetic architecture of dynamic traits of agricultural values. PMID:20196894

  10. Spatial Thinking and Visualisation of Real-World Concepts using GeoMapApp

    Goodwillie, A. M.

    2015-12-01

    Commonly, geoscience data is presented to students in the lab and classroom in the form of data tables, maps and graphs. Successful data interpretation requires learners to become proficient with spatial thinking skills, allowing them to gain insight and understanding of the underlying real-world 3-D processes and concepts. Yet, educators at both the school and university level often witness students having difficulty in performing that translation. As a result, tools and resources that help to bridge that spatial capability gap can have useful application in the educational realm. A free, map-based data discovery and visualisation tool developed with NSF funding at Lamont-Doherty Earth Observatory caters to students and teachers alike by providing a variety of data display and manipulation techniques that enhance geospatial awareness. Called GeoMapApp (http://www.geomapapp.org), the tool provides access to hundreds of built-in authentic geoscience data sets. Examples include earthquake and volcano data, geological maps, lithospheric plate boundary information, geochemical, oceanographic, and environmental data. Barriers to entry are lowered through easy installation, seamless integration of research-grade data sets, intuitive menus, and project-saving continuity. The default base map is a cutting-edge elevation model covering the oceans and land. Dynamic contouring, artificial illumination, 3-D visualisations, data point manipulations, cross-sectional profiles, and other display techniques help students grasp the content and geospatial context of data. Data sets can also be layered for easier comparison. Students may import their own data sets in Excel, ASCII, shapefile, and gridded format, and they can gain a sense of ownership by being able to tailor their data explorations and save their own projects. GeoMapApp is adaptable to a range of learning environments from lab sessions, group projects, and homework assignments to in-class pop-ups. A new Save Session

  11. Tracking the stages of learning: concept maps as representations of liminal space

    John Cuthell

    2012-01-01

    Full Text Available The concept of liminal space has recently been applied to ways of learning: the learning journey through this space encounters difficulties and misunderstandings, that are resolved as knowledge is mastered. Since 1992 the MirandaNet Fellowship, a growing international community of educators, has investigated the ways in which this relates to the collaborative learning in the liminal space of the Internet. These professionals have explored social networking, microblogging, digital mind mapping, distributed video and other innovative technologies to determine how they can be deployed through grassroots collaboration to build the theory and practice of new professional knowledge. The use of collaborative digital mind maps affords tools for the analysis of the stages and development of collaborative learning. From these shared liminal spaces beyond the screen provocative questions emerge about the relationship between learning, collaboration and innovation.

  16. What is strategy? The concept and model for its application in the Czech security strategy

    Jan Ludvík

    2011-06-01

    Full Text Available The article conceptually explains the notion of strategy. Drawing on its understanding by well-established authorities like Carl von Clausewitz, Basil Liddel Hart, André Beaufre, or Colin Gray, the authors discuss strengths and weaknesses of various views. Furthermore, the article employs Arthur Lykke’s definition of strategy to demonstrate various conceptual requirements. Strategy is thus perceived as the relationship among means, ends, and ways. Crucial implications for a development of the Czech strategic documents are further examined. The article argues that, the vital importance of coherent interconnection of all the afore-mentioned parts of the strategy has been so far neglected in this process. It is suggested that particular attention should be paid to the clear formulation of a goal, which is the prerequisite for any meaningful strategy. However, any goals must be developed with the close relation to the available or potentially attainable resources, and purposeful ways how to employ them. The whole process is best described as the hermeneutic circle.

The methodology used is based on Text mining ideas and procedures applied to a sample of documents of formulating competences of different grades taken from several Spanish universities, public and private, along with some documents used as reference by many of the universities in designing the new degrees. Based on the concepts of the dictionary, the documental corpus was endowed with a structure founded on the codification of competences formulations with these concepts. The structure introduced in the corpus of documents allowed us to identify educational profiles characteristic of each degree described in terms of the various components and subcomponents of competences. In addition, considering the corresponding coefficient of proximity between the concepts in the dictionary and the application of the techniques of multidimensional scaling and correspondence analysis allowed to create maps of concepts to represent the closeness or distance between the different subcomponents of competences, to identify cluster of similarity among them, to found neighborhood cluster in degrees and to establish levels of proximity between the various concepts and degrees. The results obtained about the similarities between grades and proximity to the various subcomponents of competencies largely agree with that expected a priori taking into account the subjects included in their curriculum and the traditional division into branches of knowledge and university schools.

  18. Supporting Students' Learning and Socioscientific Reasoning About Climate Change—the Effect of Computer-Based Concept Mapping Scaffolds

    Eggert, Sabina; Nitsch, Anne; Boone, William J.; Nückles, Matthias; Bögeholz, Susanne

    2016-01-01

    Climate change is one of the most challenging problems facing today's global society (e.g., IPCC 2013). While climate change is a widely covered topic in the media, and abundant information is made available through the internet, the causes and consequences of climate change in its full complexity are difficult for individuals, especially non-scientists, to grasp. Science education is a field which can play a crucial role in fostering meaningful education of students to become climate literate citizens (e.g., NOAA 2009; Schreiner et al., 41, 3-50, 2005). If students are, at some point, to participate in societal discussions about the sustainable development of our planet, their learning with respect to such issues needs to be supported. This includes the ability to think critically, to cope with complex scientific evidence, which is often subject to ongoing inquiry, and to reach informed decisions on the basis of factual information as well as values-based considerations. The study presented in this paper focused on efforts to advance students in (1) their conceptual understanding about climate change and (2) their socioscientific reasoning and decision making regarding socioscientific issues in general. Although there is evidence that "knowledge" does not guarantee pro-environmental behavior (e.g. Schreiner et al., 41, 3-50, 2005; Skamp et al., 97(2), 191-217, 2013), conceptual, interdisciplinary understanding of climate change is an important prerequisite to change individuals' attitudes towards climate change and thus to eventually foster climate literate citizens (e.g., Clark et al. 2013). In order to foster conceptual understanding and socioscientific reasoning, a computer-based learning environment with an embedded concept mapping tool was utilized to support senior high school students' learning about climate change and possible solution strategies. The evaluation of the effect of different concept mapping scaffolds focused on the quality of student

  2. Integrated environmental mapping and monitoring, a methodological approach to optimise knowledge gathering and sampling strategy.

    Nilssen, Ingunn; Ødegård, Øyvind; Sørensen, Asgeir J; Johnsen, Geir; Moline, Mark A; Berge, Jørgen

    2015-07-15

    New technology has led to new opportunities for a holistic environmental monitoring approach adjusted to purpose and object of interest. The proposed integrated environmental mapping and monitoring (IEMM) concept, presented in this paper, describes the different steps in such a system from mission of survey to selection of parameters, sensors, sensor platforms, data collection, data storage, analysis and to data interpretation for reliable decision making. The system is generic; it can be used by authorities, industry and academia and is useful for planning- and operational phases. In the planning process the systematic approach is also ideal to identify areas with gap of knowledge. The critical stages of the concept is discussed and exemplified by two case studies, one environmental mapping and one monitoring case. As an operational system, the IEMM concept can contribute to an optimised integrated environmental mapping and monitoring for knowledge generation as basis for decision making. PMID:25956441

  5. Application of concept mapping principles to managing steam generator knowledge at CNSC

    Nuclear knowledge management (KM) initiatives have been observed in many international agencies, industries and research facilities, such as the International Atomic Energy Agency (IAEA) and Canada.s own Atomic Energy of Canada Limited (AECL). This paper presents a brief overview of the theory behind concept mapping, its origins and application potential in an organizational context. Successful applications of nuclear KM efforts by the IAEA, the Defence Threat Reduction Agency (DTRA), AECL and the Organization for Economic Cooperation and Development, Nuclear Energy Agency (OECD/NEA) are specifically highlighted in the report for comparison and contrast. In addition, a system based on concept mapping theory is recently designed and implemented in order to efficiently manage steam generator-related knowledge at the Canadian Nuclear Safety Commission (CNSC). This tool aims to act as a powerful information asset for storage and retrieval of explicit and implicit knowledge, and to integrate KM practices into the CNSC workplace, all while maintaining its simplicity and ease for future modifications and fine-tuning when needed.

  6. Using Author Bylines and Concept Maps to Illustrate the Connectedness of Scientists

    Min-Ken Liao

    2013-02-01

    Full Text Available Incorporating reading and discussing primary articles in undergraduate courses has been shown to enhance students’ learning, stimulate their interests in science, and retain them as science majors.  While instructors diligently coach students to scrutinize every section in an article thoroughly and critically, the author byline is often overlooked.  In this study, the author bylines of primary articles were used to illustrate the connectedness of scientists and the collaborative nature of science.  First year college students first learned how to construct a concept map and used concept maps to connect 14 scientists with 14 primary articles that these scientists authored.  In doing so, students visualized and understood science as human activity and science progresses as a community effort.  Pre- and post-activity questionnaires were used to evaluate whether the activity objectives were met.  Students further examined the structure and organization of a primary article after the activity and they were engaged in discussions such as how research ideas developed and evolved, the advantages and disadvantages of collaborative research, the ethics of authorships, graduate schools, and careers in science. Hopefully, perceiving the authors of primary articles as real people in a social network and science as the collaborative efforts may help students see themselves being a part of the scientific advancement and inspire them to pursue careers in science.

  7. Concept maps: A tool for knowledge management and synthesis in web-based conversational learning.

    2016-01-01

    Web-based conversational learning provides an opportunity for shared knowledge base creation through collaboration and collective wisdom extraction. Usually, the amount of generated information in such forums is very huge, multidimensional (in alignment with the desirable preconditions for constructivist knowledge creation), and sometimes, the nature of expected new information may not be anticipated in advance. Thus, concept maps (crafted from constructed data) as "process summary" tools may be a solution to improve critical thinking and learning by making connections between the facts or knowledge shared by the participants during online discussion This exploratory paper begins with the description of this innovation tried on a web-based interacting platform (email list management software), FAIMER-Listserv, and generated qualitative evidence through peer-feedback. This process description is further supported by a theoretical construct which shows how social constructivism (inclusive of autonomy and complexity) affects the conversational learning. The paper rationalizes the use of concept map as mid-summary tool for extracting information and further sense making out of this apparent intricacy. PMID:27563577

  9. A new multicriteria risk mapping approach based on a multiattribute frontier concept.

    Yemshanov, Denys; Koch, Frank H; Ben-Haim, Yakov; Downing, Marla; Sapio, Frank; Siltanen, Marty

    2013-09-01

    Invasive species risk maps provide broad guidance on where to allocate resources for pest monitoring and regulation, but they often present individual risk components (such as climatic suitability, host abundance, or introduction potential) as independent entities. These independent risk components are integrated using various multicriteria analysis techniques that typically require prior knowledge of the risk components' importance. Such information is often nonexistent for many invasive pests. This study proposes a new approach for building integrated risk maps using the principle of a multiattribute efficient frontier and analyzing the partial order of elements of a risk map as distributed in multidimensional criteria space. The integrated risks are estimated as subsequent multiattribute frontiers in dimensions of individual risk criteria. We demonstrate the approach with the example of Agrilus biguttatus Fabricius, a high-risk pest that may threaten North American oak forests in the near future. Drawing on U.S. and Canadian data, we compare the performance of the multiattribute ranking against a multicriteria linear weighted averaging technique in the presence of uncertainties, using the concept of robustness from info-gap decision theory. The results show major geographic hotspots where the consideration of tradeoffs between multiple risk components changes integrated risk rankings. Both methods delineate similar geographical regions of high and low risks. Overall, aggregation based on a delineation of multiattribute efficient frontiers can be a useful tool to prioritize risks for anticipated invasive pests, which usually have an extremely poor prior knowledge base.

  10. On the Use of Concept Maps as an Assessment Tool in Science: What we have Learned so Far

    María Araceli Ruiz Primo

    2000-05-01

    Full Text Available In this paper I describe concept maps as an assessment tool to measure one aspect of achievement, the organization of propositional (declarative knowledge in a domain. A concept map-based assessment consists of a task that elicits structured knowledge, a response format, and a scoring system. Variation in tasks, response formats, and scoring systems produce different mapping techniques that may elicit different knowledge representations, posing construct-interpretation challenges. This paper provides an overview of the research on the technical characteristics of concept maps. It briefly describes some of the studies that have been conducted to this end, and what we have learned so far about this form of assessment.

    Full Text Available Organizational Strategy for companies ensures targeting and positioning strategic in the current context. However, understanding of the term, its meaning, needs further reflection on its setting to suppress doubts from the perspective of the managers. Thus, the aim of this work is to identify the image of organizational strategy from the perspective of managers linked to building, in a city of Serra Gaucha. With regard to the research method, was employed the Technical of Configuration Ideational Images (TCID, which is a variation of the ICM (Image Configuration Method; where ICM consists of a configuration technique of objects’ image more "tangible" and the TCID technique configuration of objects’ image "intangible", purely ideational (DE TONI et al., 2006. Twenty interviews were conducted with managers, in November and December of 2010. Results of this study showed 32 attributes, which were distributed among five dimensions of strategy, proposed by Mintzberg (1987, the Five Ps – plan, pretext, pattern, position and perspective. The study allows the observation image that respondents, company managers, have in relation to the concept of Organizational Strategy. Results of this study identified that the management searched for the term strategy is more related to the dimensions Plan and Perspective. Among contributions of this paper can be highlighted of propose a method that helps to better understand the configuration of a concept, in this case, the Organizational Strategy.

    1993-01-01

    The design of an IR mapping spectrometer that exceeds all the criteria of the Pluto Fast Flyby Mission will be presented. The instrument has a mass of approximately 1700 g and uses less than 4 W of power. The design concept is based on an f/3 spectrograph using an aberration-corrected concave holographic grating. Up to four spectral regions can be covered simultaneously by dividing the grating into two to four sections, each imaging the entrance slit on a different area of the array. The spectrography will be fed by a lightweight 5 in. f/3 telescope based on SDIO precepts. In order to provide spectroscopic access to the fundamental molecule frequencies, an extended-range NICMOS array to approximately 3.5 microns and an InSb array going to 5.8 microns will be considered.

  16. Discovering Abstract Concepts to Aid Cross-Map Transfer for a Learning Agent

    Herpson, Cédric; Corruble, Vincent

    The capacity to apply knowledge in a context different than the one in which it was learned has become crucial within the area of autonomous agents. This paper specifically addresses the issue of transfer of knowledge acquired through online learning in partially observable environments. We investigate the discovery of relevant abstract concepts which help the transfer of knowledge in the context of an environment characterized by its 2D geographical configuration. The architecture proposed is tested in a simple grid-world environment where two agents duel each other. Results show that an agent’s performances are improved through learning, including when it is tested on a map it has not yet seen.

    AIM:To present a novel strategy for mapping quantitative trait loci (QTL), using human metapopulations. The strategy is based on the expectation that in geographic clusters of small and distinct human isolates, a combination of founder effect and genetic drift can dramatically increase population frequency of rare QTL variants with large effect. In such cases, the distribution of QT measurements in an (affected) isolate is expected to deviate from that observed in neighboring isolates.METHODS...

  19. A synaptic strategy for consolidation of convergent visuotopic maps.

    Phillips, Marnie A; Colonnese, Matthew T; Goldberg, Julie; Lewis, Laura D; Brown, Emery N; Constantine-Paton, Martha

    2011-08-25

    The mechanisms by which experience guides refinement of converging afferent pathways are poorly understood. We describe a vision-driven refinement of corticocollicular inputs that determines the consolidation of retinal and visual cortical (VC) synapses on individual neurons in the superficial superior colliculus (sSC). Highly refined corticocollicular terminals form 1-2 days after eye-opening (EO), accompanied by VC-dependent filopodia sprouting on proximal dendrites, and PSD-95 and VC-dependent quadrupling of functional synapses. Delayed EO eliminates synapses, corticocollicular terminals, and spines on VC-recipient dendrites. Awake recordings after EO show that VC and retina cooperate to activate sSC neurons, and VC light responses precede sSC responses within intervals promoting potentiation. Eyelid closure is associated with more protracted cortical visual responses, causing the majority of VC spikes to follow those of the colliculus. These data implicate spike-timing plasticity as a mechanism for cortical input survival, and support a cooperative strategy for retinal and cortical coinnervation of the sSC. PMID:21867886

    One of the most significant challenges facing any health care leader today is that of building commitment among followers. The last decade, with its tumultuous changes in our organizations, left many employees emotionally detached from their workplace. Mistrust, increasing cynicism, escalating financial pressures, and continuing challenges adversely impact our workforce's organizational commitment. The author explores the concept of commitment, which can serve as a basis for developing practical effective retention strategies. PMID:15192998

  1. Mentoring Entrepreneurial Networks: mapping conceptions of participants in technological-based business incubators in Brazil.

    Pontes Regis, Helder

    2007-12-01

    Full Text Available The recent entrepreneurship research agenda includes the analysis of cognitive structures of successful entrepreneurs, revealing an important tool for the examination of an entrepreneurial career. Using techniques of cognitive maps, this study explores the concepts of a successful career and the network itself, as a whole, for career development. Fifty-three entrepreneurs were studied, in seven technological incubators in the city of Recife, Pernambuco, Brazil. Specifically, this study aimed to map the shared meanings of the incubated entrepreneurs regarding informal support networks. Such networks support the entrepreneurial career and the present study explores the characteristics and the conceptual model that underlies the networks. The data collection was achieved through interviews through a free evocation technique. The shared meanings indicate the existence of inherent thought categories that support network context in the incubator environment, mainly the mentoring networks. The results endorse the interpretation of an informal mentoring model emerging from the dominant evocations concerning a successful career and of the network itself as promoter of career development.

  2. Equity and health policy in Africa: Using concept mapping in Moore (Burkina Faso

    Ridde Valéry

    2008-04-01

    Full Text Available Abstract Background This methodological article is based on a health policy research project conducted in Burkina Faso (West Africa. Concept mapping (CM was used as a research method to understand the local views of equity among stakeholders, who were concerned by the health policy under consideration. While this technique has been used in North America and elsewhere, to our knowledge it has not yet been applied in Africa in any vernacular language. Its application raises many issues and certain methodological limitations. Our objective in this article is to present its use in this particular context, and to share a number of methodological observations on the subject. Methods Two CMs were done among two different groups of local stakeholders following four steps: generating ideas, structuring the ideas, computing maps using multidimensional scaling and cluster analysis methods, and interpreting maps. Fifteen nurses were invited to take part in the study, all of whom had undergone training on health policies. Of these, nine nurses (60% ultimately attended the two-day meeting, conducted in French. Of 45 members of village health committees who attended training on health policies, only eight were literate in the local language (Moore. Seven of these (88% came to the meeting. Results The local perception of equity seems close to the egalitarian model. The actors are not ready to compromise social stability and peace for the benefit of the worst-off. The discussion on the methodological limitations of CM raises the limitations of asking a single question in Moore and the challenge of translating a concept as complex as equity. While the translation of equity into Moore undoubtedly oriented the discussions toward social relations, we believe that, in the context of this study, the open-ended question concerning social justice has a threefold relevance. At the same time, those limitations were transformed into strengths. We understand that it was

  7. SPECIALIZED MAPPING OF CRUSTAL FAULT ZONES. PART 1: BASIC THEORETICAL CONCEPTS AND PRINCIPLES

    K. Zh. Seminsky

    2015-09-01

    Full Text Available Long-term studies of shear zones have included collection of data on fractures showing no indication of displacement which are termed as 'blank' fractures. A method aimed at mapping fault structures and stress fields has been developed on the basis of results of paragenetic analysis of measurements of abundant fractures. The method is termed as 'specialized mapping', firstly, due to its specific structural goal so that to distinguish it from the conventional geological mapping of regions in nature, and, secondly, because of the specific procedure applied to refer to fractures as references to decipher fault-block patterns of natural regions. In Part 1, basic theoretical concepts and principles of specialized mapping are described. Part 2 is being prepared for publication in one of the next issues of the journal; it will cover stages of the proposed method and describe some of the cases of its application.In terms of general organizational principles, specialized mapping is similar to other methods based on structural paragenetic analysis and differs from such methods in types of paragenesises viewed as references to reveal crustal fault zones. Such paragenesises result from stage-by-stage faulting (Fig 2 and Fig. 7 during which stress fields of the 2nd order are regularly changeable within the shear zone. According to combined experimental and natural data, a complete paragenesis of fractures in the shear zone includes a major (1st order fault plane and fractures of other seven types, R, R’, n, n’, t, t’ and T (2nd order (Fig. 4 and Fig 8. At the fracture level, each of them corresponds to a paragenesis including three nearly perpendicular systems of early ruptures (Fig. 1, which are based on two classical patterns of conjugated fractures, one of which is consistent with the position of the fault plane (Fig. 3. Taking into account that strike-slip, reverse and normal faults are similar in terms of mechanics (i.e. they are formed due to

  9. Does the mind map learning strategy facilitate information retrieval and critical thinking in medical students?

    Olson Valerie G

    2010-09-01

    Full Text Available Abstract Background A learning strategy underutilized in medical education is mind mapping. Mind maps are multi-sensory tools that may help medical students organize, integrate, and retain information. Recent work suggests that using mind mapping as a note-taking strategy facilitates critical thinking. The purpose of this study was to investigate whether a relationship existed between mind mapping and critical thinking, as measured by the Health Sciences Reasoning Test (HSRT, and whether a relationship existed between mind mapping and recall of domain-based information. Methods In this quasi-experimental study, 131 first-year medical students were randomly assigned to a standard note-taking (SNT group or mind map (MM group during orientation. Subjects were given a demographic survey and pre-HSRT. They were then given an unfamiliar text passage, a pre-quiz based upon the passage, and a 30-minute break, during which time subjects in the MM group were given a presentation on mind mapping. After the break, subjects were given the same passage and wrote notes based on their group (SNT or MM assignment. A post-quiz based upon the passage was administered, followed by a post-HSRT. Differences in mean pre- and post-quiz scores between groups were analyzed using independent samples t-tests, whereas differences in mean pre- and post-HSRT total scores and subscores between groups were analyzed using ANOVA. Mind map depth was assessed using the Mind Map Assessment Rubric (MMAR. Results There were no significant differences in mean scores on both the pre- and post-quizzes between note-taking groups. And, no significant differences were found between pre- and post-HSRT mean total scores and subscores. Conclusions Although mind mapping was not found to increase short-term recall of domain-based information or critical thinking compared to SNT, a brief introduction to mind mapping allowed novice MM subjects to perform similarly to SNT subjects.

    Safer conception interventions can significantly reduce the risk of horizontal HIV transmission between HIV-serodiscordant partners. However, prior to implementing safer conception interventions, it is essential to understand potential barriers to their adoption so that strategies can be developed to overcome these barriers. This paper examines potential barriers to the adoption of safer conception strategies by HIV-affected couples in Iringa, Tanzania using an ecological framework. We interviewed 30 HIV-positive women, 30 HIV-positive men and 30 health providers engaged in delivering HIV-related services. We also conducted direct observations at five health facilities. Findings suggest that there are multiple barriers to safer conception that operate at the individual, relational, environmental, structural, and super-structural levels. The barriers to safer conception identified are complex and interact across these levels. Barriers at the individual level included antiretroviral adherence, knowledge of HIV status, knowledge and acceptability of safer conception strategies, and poor nutrition. At the relational level, unplanned pregnancies, non-disclosure of status, gendered power dynamics within relationships, and patient-provider interactions posed a threat to safer conception. HIV stigma and distance to health facilities were environmental barriers to safer conception. At the structural level there were multiple barriers to safer conception, including limited safer conception policy guidelines for people living with HIV (PLHIV), lack of health provider training in safer conception strategies and preconception counseling for PLHIV, limited resources, and lack of integration of HIV and sexual and reproductive health services. Poverty and gender norms were super-structural factors that influenced and reinforced barriers to safer conception, which influenced and operated across different levels of the framework. Multi-level interventions are needed to ensure

  1. Strategy to Improvement Sustainability of Distinctively Local Snacks Based on Evaluation and Profile Mapping of SMEs Distinctively Local Snacks

    Yulia Nurendah

    2015-01-01

    Full Text Available SMEs snacks include in group industries which develop quite progressively in Indonesia. There are typical regional food or local food specialties which have been distinctively long-grown specifically in an area, however there are also some food specialties which are area-based potentially developed. Therefore, efforts to develop and empower SMEs distinctively local snacks should be done to be able to increase its competitiveness in facing the globalization and the free market.The objective of Profile Mapping of SMEs is that the development of distinctively local snacks can be implemented in an integrated, focused way, and on target. If SMEs snacks get special attention with the pattern of development and directed policy, it will become the backbone of the rise of the real sector in the region.  The study of profile mapping of SMEs distinctively local snacks is conducted by combining descriptive research method based on the results of field surveys combined with SWOT analysis Data processing and analysis with Profile Mapping of SMEs Snacks, Performance Analysis and Competitive Strategy of SMEs Snacks, SWOT Analysis, Strategy and Feasibility and concept Development models of SMEs Snacks. Bakpia becomes a top priority as a superior snack product from Jogjakarta (DIY, which can be further developed in the process of production and marketing. The attributes of main and additional ingredients, water supply, and production tools are still in average performance. In this case, the performance measure is based on the perception of bakpia producers in medium scale, while there are expectations on a high scale. Thus, there needs to be an increase in these attributes. After knowing the score of IFA, then a right strategy to be applied for SMEs position is a strategy of growth through horizontal integration which is an activity to expand SMEs by building in another location and increasing the variety of products and services. When referring to the SWOT

    Rapid, automated determination of the mapping of free text phrases to pre-defined concepts could assist in the annotation of clinical notes and increase the speed of natural language processing systems. The aim of this study was to design and evaluate a token-order-specific naïve Bayes-based machine learning system (RapTAT) to predict associations between phrases and concepts. Performance was assessed using a reference standard generated from 2860 VA discharge summaries containing 567,520 phrases that had been mapped to 12,056 distinct Systematized Nomenclature of Medicine - Clinical Terms (SNOMED CT) concepts by the MCVS natural language processing system. It was also assessed on the manually annotated, 2010 i2b2 challenge data. Performance was established with regard to precision, recall, and F-measure for each of the concepts within the VA documents using bootstrapping. Within that corpus, concepts identified by MCVS were broadly distributed throughout SNOMED CT, and the token-order-specific language model achieved better performance based on precision, recall, and F-measure (0.95±0.15, 0.96±0.16, and 0.95±0.16, respectively; mean±SD) than the bag-of-words based, naïve Bayes model (0.64±0.45, 0.61±0.46, and 0.60±0.45, respectively) that has previously been used for concept mapping. Precision, recall, and F-measure on the i2b2 test set were 92.9%, 85.9%, and 89.2% respectively, using the token-order-specific model. RapTAT required just 7.2ms to map all phrases within a single discharge summary, and mapping rate did not decrease as the number of processed documents increased. The high performance attained by the tool in terms of both accuracy and speed was encouraging, and the mapping rate should be sufficient to support near-real-time, interactive annotation of medical narratives. These results demonstrate the feasibility of rapidly and accurately mapping phrases to a wide range of medical concepts based on a token-order-specific naïve Bayes model and

    2015-08-01

    Women with serious mental illness (SMI) have disproportionately worse breast cancer profiles than those of other women. The purpose of this project was to examine barriers to and facilitators of breast cancer screening, specifically in formerly homeless women with SMI using the participatory methodology of concept mapping. A series of three concept mapping focus groups were held with 27 women over the age of 40 with a diagnosis of a SMI who live in supportive housing programs, and with 16 housing program staff. Data from the focus groups were combined through multidimensional scaling to create a visual cluster map. Barriers and facilitators to mammography screening generated by the participants clustered into eight categories. Participants rated addressing educational issues as most important and feasible. Interventions designed to improve mammogram screening in this population should address patients' perception of personal risk and should target education and support systems as modifiable factors.

It presents a process-based systems engineering model for the successful configuration management of the products generated during the operation of the design organization as a business entity. The DCMP model focuses on Pro/E and associated activities and information. It can serve as the framework for interconnecting all essential aspects of the product design business. A design operation scenario offers a sense of how to do business at a time when DCMP is second nature within the design organization.

  5. Supplier bidding strategy based on non-cooperative game theory concepts in single auction power pools

    In single auction power pools, only generators bid several energy price segments depending on the amount of energy supply, at individual generating companies' (GENCO) own discretion, for every trading interval. Then all selected bidders are paid a uniform Market Clearing Price (MCP). In this paper, it is realized that each GENCO has the complete information on its own payoff as well as the other parties' payoffs, corresponding to each potential combination of choices of strategies by all the players. Specifically, all the suppliers attempt to estimate the others' bids using the concept of Nash equilibrium in the general sense of profit maximization. Under some simplified assumptions, this problem can be modeled as a simultaneous-move game confronted by the bidders. Here, the system demand forecast by competitive sellers is captured for the purpose of constructing the optimal bidding strategy. Finally, a numerical example is presented demonstrating the effectiveness of the proposed solution scheme. (author)

  7. The effect of the use of concept maps on community college students' conceptual understanding of biology course content

    Wells, Franklin Brian

    Purpose of the study. The major purpose of this study was to measure the change, if any, in students' conceptual understanding of biology course content using concept maps (experimental) or a standard lecture format (control). In addition, the effectiveness of the use of concept maps as advance organizers was measured according to the various subgroups of cognitive development level, age, ethnicity, gender, class time, and educational background. A final concern was the relationships between conceptual understanding of biology course content and the students' cognitive development level. Procedure. A quasi-experimental design was used to conduct the study during a sixteen-week semester. The study was conducted during the fall, 1997, semester at a community college using 190 students enrolled in General Biology 1406. Major data were collected using a pretest, posttest, and the Test of Logical Thinking. Data were treated through the application of analysis of covariance, Pearson product-moment correlation, and the Fisher Z-transformation technique. Findings. The findings of this investigation were as follows: (1) Concept maps used as advance organizers had a significant effect on student conceptual understanding of biology course content. (2) The use of concept maps as advance organizers had a significant effect on student conceptual understanding of biology when students are classified according to their cognitive developmental level, age, gender, major, course time, and educational background. (3) A significant relationship between cognitive developmental level and conceptual understanding was also found. Conclusions. The use of concept maps, as advance Organizers, is an effective method for improving student learning in general biology classes. A positive relationship exists between students' cognitive developmental level and conceptual understanding.

  8. Scientific concepts for hydroacoustic seafloor mapping in the coastal zone and beyond

    Hydroacoustic seafloor mapping is a reliable and cost-effective method to investigate and monitor the seafloor in high spatial and temporal resolution. The results are important for the evaluation of benthic habitats and help to identify vulnerable environments that require protection. Yet, how can we overcome the problems that occur when different gear produces different results, which are evaluated by people that have different points of view and different backgrounds? These aspects form an integer part of the project WIMO ("Scientific concepts for monitoring the German Bight, SE North Sea", Subproject 1.1: "Hydroacoustic Habitat Mapping"). It aims at comparing different hydroacoustic gear, methodologies and workflows in order to work out basic routines for universal use in marine benthic habitat mapping. The project investigates a number of target areas in the German Bight (North Sea) using different sidescan sonars (SSS), acoustic seafloor-classification systems (AGDS), multibeams, and different sampling and grain-size analytical methods as well as sea-floor imaging methods. We tested different gear on different ships, on the same ship but not synchronously, and as many instruments as possible measuring at the same time on the same ship. Our results suggest that guidelines and requirements for surveys can hardly be standardized as they depend largely on the water depth, the seabed, and on the vessel and the equipment available. All of these frame conditions usually differ from survey to survey. Taking this into account, we present a reasonable workflow for time and cost-effective benthic habitat mapping and monitoring. Transect-line distances as well as monitoring frequencies, number and positioning of ground-truth samples and seabed imaging are discussed. We recommend frequency combinations and appropriate swath widths and overlaps for SSS and show a way to ground-truth lower-frequency data using high-frequency data. Acoustic ground discrimination systems are

    Background Effective communication is a critical component in ensuring that children are fully vaccinated. Although numerous communication interventions have been proposed and implemented in various parts of Nigeria, the range of communication strategies used has not yet been mapped systematically. This study forms part of the ‘Communicate to vaccinate’ (COMMVAC) project, an initiative aimed at building research evidence for improving communication with parents and communities about childhood vaccinations in low- and middle-income countries. Objective This study aims to: 1) identify the communication strategies used in two states in Nigeria; 2) map these strategies against the existing COMMVAC taxonomy, a global taxonomy of vaccination communication interventions; 3) create a specific Nigerian country map of interventions organised by purpose and target; and 4) analyse gaps between the COMMVAC taxonomy and the Nigerian map. Design We conducted the study in two Nigerian states: Bauchi State in Northern Nigeria and Cross River State in Southern Nigeria. We identified vaccination communication interventions through interviews carried out among purposively selected stakeholders in the health services and relevant agencies involved in vaccination information delivery; through observations and through relevant documents. We used the COMMVAC taxonomy to organise the interventions we identified based on the intended purpose of the communication and the group to which the intervention was targeted. Results The Nigerian map revealed that most of the communication strategies identified aimed to inform and educate and remind or recall. Few aimed to teach skills, enhance community ownership, and enable communication. We did not identify any intervention that aimed to provide support or facilitate decision-making. Many interventions had more than one purpose. The main targets for most interventions were caregivers and community members, with few interventions directed at

  10. Thailand nuclear strategies and directives: Going forward with cooperation and collaboration concepts

    Counter terrorism and improved quarantine intervention remain top priorities as well as intercepting illicit drugs and other things potentially harmful to the community. Thailand has experiences and lessons learned from the events that benefit the future implementation of activities in the country relevant to nuclear and radiological security as well as protection against nuclear and radiological terrorism. The governments of all countries in which major radiation sources are used should be rigorously encouraged to adopt the Convention on Early Notification of a Nuclear Accident as well as the Convention on Assistance in the Case of a Nuclear Accident or Radiological Emergency. Thailand, as the member of ASEAN, SEANWFZ, IAEA, etc., realizes the importance of cooperation and collaboration concepts to be used as the country nuclear security strategies and directives to counterattack the terrorists. National authorities should be encouraged to cooperate and share information with the IAEA and with other Member States to help prevent or mitigate the consequences of the successful attack. Cooperation and collaboration of various organizations is also an important concept for going forward strategies and directives of which much still remains to be improved. (author)

  11. A polypill strategy to improve global secondary cardiovascular prevention: from concept to reality.

    Castellano, José M; Sanz, Ginés; Fernandez Ortiz, Antonio; Garrido, Ester; Bansilal, Sameer; Fuster, Valentin

    2014-08-12

    The prevention of cardiovascular disease (CVD) by using a polypill has gained increasing momentum as a strategy to contain progression of the disease. Since its initial conception just over a decade ago, only a handful of trials have been completed assessing the efficacy and safety of this innovative concept. The results of these trials have supported the viability of the polypill in CVD prevention and management, albeit with a few caveats, essentially related to the lack of evidence on the effect of the polypill to effectively reduce cardiovascular events. The polypill has the potential to control the global health epidemic of CVD by effectively reaching underdeveloped regions of the world, simplifying healthcare delivery, improving cost-effectiveness, increasing medication adherence, and supporting a comprehensive prescription of evidence-based cardioprotective drugs. Major trials underway will provide definitive evidence on the efficacy of the polypill in reducing cardiovascular events in a cost-effective manner. The results of these studies will determine whether a polypill strategy can quell the burgeoning public health challenge of CVD and will potentially provide the evidence to implement an effective, simple, and innovative solution to restrain the global CVD pandemic.

  12. High resolution digital soil mapping as a future instrument for developing sustainable landuse strategies

    Gries, Philipp; Funke, Lisa-Marie; Baumann, Frank; Schmidt, Karsten; Behrens, Thorsten; Scholten, Thomas

    2016-04-01

    Climate change, increase in population and intensification of land use pose a great challenge for sustainable handling of soils. Intelligent landuse systems are able to minimize and/or avoid soil erosion and loss of soil fertility. A successful application of such systems requires area-wide soil information with high resolution. Containing three consecutive steps, the project INE-2-H („innovative sustainable landuse") at the University of Tuebingen is about creating high-resolution soil information using Digital Soil Mapping (DSM) techniques to develop sustainable landuse strategies. Input data includes soil data from fieldwork (texture and carbon content), the official digital soil and geological map (1:50.000) as well as a wide selection of local, complex and combined terrain parameters. First, soil maps have been created using the DSM approach and Random Forest (RF). Due to high resolution (10x10 m pixels), those maps show a more detailed spatial variability of soil information compared to the official maps used. Root mean square errors (RMSE) of the modelled maps vary from 2.11 % to 6.87 % and the coefficients of determination (R²) go from 0.42 to 0.68. Second, soil erosion potentials have been estimated according to the Universal Soil Loss Equation (USLE). Long-term average annual soil loss ranges from 0.56 to 24.23 [t/ha/a]. Third, combining high-resolution erosion potentials with expert-knowledge of local farmers will result in a landuse system adapted to local conditions. This system will include sustainable strategies reducing soil erosion and conserving soil fertility.

  13. Visualisation of Astronomy domain: a `mapping' strategy in teaching and learning astronomy

    Gulyaev, S.

    2006-08-01

    If you were to overhear several students talking, you might hear one of them say, our professors have stuffed us full, but what does it all mean? Many tertiary students are unable to perceive where all the information they have been given about a particular area of astronomy actually fits into astronomy as a whole. Furthermore, even graduates of astronomy are often unable to conceptualise and understand their field of astronomy and astronomical endeavours. Our students' vision of astronomy is similar to the situation with a metro (underground) passenger. You get out to the surface on one station and see a beautiful square with the monument and buildings around. As you come up to the other station you can see a park and a river. But what is between? What streets, roads or pathways connect these areas? Where does one area transit or transfer to the other? In tertiary education, each paper or module is like one metro station. Students' knowledge is fragmentary; they lack long-term understanding of astronomy content, much less the ability to apply it. Our students need a map of this city - a map of astronomy. Application of a concept of educational `science maps' to astronomy education is discussed. By analogy with geographic maps, scales of educational science maps - scales of integration - are introduced. Science maps of different scales are illustrated with initial examples exploring the application of this methodology in astronomy, astrophysics and geophysics. There is a significant amount of work to be done by experts in specific fields of astronomy. It is incumbent upon scientists to conceptualise and define how maps of their fields might be drawn, so that educators might utilise them more fully in developing their practice and their students learning in astronomy.

  14. Primary School Student Teachers' Understanding of Climate Change: Comparing the Results Given by Concept Maps and Communication Analysis

    Ratinen, Ilkka; Viiri, Jouni; Lehesvuori, Sami

    2012-11-01

    Climate change is a complex environmental problem that can be used to examine students' understanding, gained through classroom communication, of climate change and its interactions. The present study examines a series of four science sessions given to a group of primary school student teachers (n = 20). This includes analysis of the communication styles used and the students' pre- and post-conceptualisation of climate change based on results obtained via essay writing and drawings. The essays and drawings concerned the students' unprompted pre- and post-conceptions about climate change, collected before and after each of the four inquiry-based science sessions (in physics, chemistry, biology and geography). Concept mapping was used in the analysis of the students' responses. The communication used in the four sessions was analysed with a communicative approach in order to find out the discussion about climate change between teacher and students. The analyses indicated that the students did not have the knowledge or the courage to participate in discussion, but post-conceptualisation map showed that students' thinking had become more coherent after the four sessions. Given the results of the present study, proposals for using concepts maps and/or communication analysis in studying students' conceptions are presented.

  18. Factors Influencing Seasonal Influenza Vaccination Uptake in Emergency Medical Services Workers: A Concept Mapping Approach.

    Subramaniam, Dipti P; Baker, Elizabeth A; Zelicoff, Alan P; Elliott, Michael B

    2016-08-01

    Seasonal influenza has serious impacts on morbidity and mortality and has a significant economic toll through lost workforce time and strains on the health system. Health workers, particularly emergency medical services (EMS) workers have the potential to transmit influenza to those in their care, yet little is known of the factors that influence EMS workers' decisions regarding seasonal influenza vaccination (SIV) uptake, a key factor in reducing potential for transmitting disease. This study utilizes a modified Theory of Planned Behavior (TPB) model as a guiding framework to explore the factors that influence SIV uptake in EMS workers. Concept mapping, which consists of six-stages (preparation, generation, structuring, representation, interpretation, and utilization) that use quantitative and qualitative approaches, was used to identify participants' perspectives towards SIV. This study identified nine EMS-conceptualized factors that influence EMS workers' vaccination intent and behavior. The EMS-conceptualized factors align with the modified TPB model and suggest the need to consider community-wide approaches that were not initially conceptualized in the model. Additionally, the expansion of non-pharmaceutical measures went above and beyond original conceptualization. Overall, this study demonstrates the need to develop customized interventions such as messages highlighting the importance of EMS workers receiving SIV as the optimum solution. EMS workers who do not intend to receive the SIV should be provided with accurate information on the SIV to dispel misconceptions. Finally, EMS workers should also receive interventions which promote voluntary vaccination, encouraging them to be proactive in the health decisions they make for themselves. PMID:26721630

    vulnerability in order to lower health risks and disease impacts. The proposed framework explains the generic concepts of disease hazard, vulnerability, risk and its connections. It can be applied to many different diseases and implemented in different ways. Statistical or dynamic disease models integrating future climate projections can - for example - be combined with forecast models. These can be evaluated against different socio-economic development pathways and feed into decisions support systems with an ultimate aim of designing the most appropriate risk reduction strategies. The paper will present first preliminary results on the mapping of vulnerability for the Eastern African region, including diseases such as Malaria, Schistosomiasis and Rift Valley Fever and conclude with current research challenges and how they will be addressed within the HEALTHY FUTURES project.

  8. A SYNCHRONIZED PROCESS BASED SCHEDULING TO IMPROVE MAP/REDUCE EXECUTION STRATEGY

    N. Barathi

    2014-11-01

    Full Text Available MapReduce is a widely used parallel computing framework for large scale data processing. The two major performance metrics in MapReduce are job execution time and cluster throughput. They can be seriously impacted by straggler machines. Speculative execution is a common approach for dealing with the straggler problem by simply backing up those slow running tasks on alternative machines. To improve speculative execution strategies MCP (Maximum Cost Performance can identify slow task and EWMA (Exponentially Weighted Moving Average to predict process speed and calculate task completion time. Multiple speculative execution strategies have been proposed, but there is a pitfall: incoming jobs are allocated to nodes present in server and fail to schedule process type allocate to node for processing. To overcome this process we proposed a new scheduling based speculative execution strategy. For scheduling we first calculate number of name node residing in server, minimum threshold of resources allocated to name node. We use minimum to avoid huge interaction among the name node when the competition for resources arises. To choose a proper work node for computing the task, we take both time scheduling and ability of work node to compute the task.

    2014-12-01

    Full Text Available The study tried to answer questions pertinent to the use of concept maps (CM as a teaching resource facilitator of meaningful learning of scientific concepts of Natural Sciences, in the classroom of elementary school. To answer the questions and insert the MC in the classroom every day, we adopted the interdependence between the process of learning, teaching and investigation. To ensure a triadic relationship, outline an intervention / investigation with theoretical and methodological support in quantitative and qualitative approach. The teaching and learning were secured from a teaching strategy, able to share and negotiate concepts relevant to the field of education, enabling students move beyond their existing knowledge, ensuring the data of research about the effects of MC in learning of the groups investigated. The MC was defined as a teaching resource potential for this level of education and principles of the Theory of Meaningful Learning that supports it. It was evident the recursive procedural character inherent in meaningful learning as using the MC as a teaching resource in the construction of scientific knowledge of Natural Sciences, the occurrence of learning of the groups using the MC and its validation in the presence of students of final grades of elementary school.

  10. Evaluating the Performance of Fine-Mapping Strategies at Common Variant GWAS Loci

    van de Bunt, Martijn; Cortes, Adrian; Brown, Matthew A.; Morris, Andrew P.; McCarthy, Mark I.

    2015-01-01

    The growing availability of high-quality genomic annotation has increased the potential for mechanistic insights when the specific variants driving common genome-wide association signals are accurately localized. A range of fine-mapping strategies have been advocated, and specific successes reported, but the overall performance of such approaches, in the face of the extensive linkage disequilibrium that characterizes the human genome, is not well understood. Using simulations based on sequence data from the 1000 Genomes Project, we quantify the extent to which fine-mapping, here conducted using an approximate Bayesian approach, can be expected to lead to useful improvements in causal variant localization. We show that resolution is highly variable between loci, and that performance is severely degraded as the statistical power to detect association is reduced. We confirm that, where causal variants are shared between ancestry groups, further improvements in performance can be obtained in a trans-ethnic fine-mapping design. Finally, using empirical data from a recently published genome-wide association study for ankylosing spondylitis, we provide empirical confirmation of the behaviour of the approximate Bayesian approach and demonstrate that seven of twenty-six loci can be fine-mapped to fewer than ten variants.

  11. A Systematic Review of Mapping Strategies for the Sonification of Physical Quantities

    Dubus, Gaël; Bresin, Roberto

    2013-01-01

    The field of sonification has progressed greatly over the past twenty years and currently constitutes an established area of research. This article aims at exploiting and organizing the knowledge accumulated in previous experimental studies to build a foundation for future sonification works. A systematic review of these studies may reveal trends in sonification design, and therefore support the development of design guidelines. To this end, we have reviewed and analyzed 179 scientific publications related to sonification of physical quantities. Using a bottom-up approach, we set up a list of conceptual dimensions belonging to both physical and auditory domains. Mappings used in the reviewed works were identified, forming a database of 495 entries. Frequency of use was analyzed among these conceptual dimensions as well as higher-level categories. Results confirm two hypotheses formulated in a preliminary study: pitch is by far the most used auditory dimension in sonification applications, and spatial auditory dimensions are almost exclusively used to sonify kinematic quantities. To detect successful as well as unsuccessful sonification strategies, assessment of mapping efficiency conducted in the reviewed works was considered. Results show that a proper evaluation of sonification mappings is performed only in a marginal proportion of publications. Additional aspects of the publication database were investigated: historical distribution of sonification works is presented, projects are classified according to their primary function, and the sonic material used in the auditory display is discussed. Finally, a mapping-based approach for characterizing sonification is proposed. PMID:24358192

  16. Efficient and robust phase unwrapping algorithm based on unscented Kalman filter, the strategy of quantizing paths-guided map, and pixel classification strategy.

    Xie, Xian Ming; Zeng, Qing Ning

    2015-11-01

    This paper presents an efficient and robust phase unwrapping algorithm which combines an unscented Kalman filter (UKF) with a strategy of quantizing a paths-guided map and a pixel classification strategy based on phase quality information. The advantages of the proposed method depend on the following contributions: (1) the strategy of quantizing the paths-guided map can accelerate the process of searching unwrapping paths and greatly reducing time consumption on the unwrapping procedure; (2) the pixel classification strategy proposed by this paper can reduce the error propagation effect by decreasing the amounts of pixels with equal quantized paths-guided value in the process of unwrapping; and (3) the unscented Kalman filter enables simultaneous filtering and unwrapping without the information loss caused by linearization of a nonlinear model. In addition, a new paths-guided map derived from a phase quality map is inserted into the strategy of quantizing the paths-guided map to provide a more robust path of unwrapping, and then ensures better unwrapping results. Results obtained from synthetic data and real data show that the proposed method can efficiently obtain better solutions with respect to some of the most used algorithms. PMID:26560585

  17. Concepts of soil mapping as a basis for the assessment of soil functions

    Baumgarten, Andreas

    2014-05-01

    Soil mapping systems in Europe have been designed mainly as a tool for the description of soil characteristics from a morphogenetic viewpoint. Contrasting to the American or FAO system, the soil development has been in the main focus of European systems. Nevertheless , recent developments in soil science stress the importance of the functions of soils with respect to the ecosystems. As soil mapping systems usually offer a sound and extensive database, the deduction of soil functions from "classic" mapping parameters can be used for local and regional assessments. According to the used pedo-transfer functions and mapping systems, tailored approaches can be chosen for different applications. In Austria, a system mainly for spatial planning purposes has been developed that will be presented and illustrated by means of best practice examples.

    2009-05-15

    The addition of a fast auxiliary power source like a supercapacitor bank in fuel cell-based vehicles has a great potential because permits a significant reduction of the hydrogen consumption and an improvement of the vehicle efficiency. The Energy Management Strategies, commanding the power split between the power sources in the hybrid arrangement to fulfil the power requirement, perform a fundamental role to achieve this objective. In this work, three strategies based on the knowledge of the fuel cell efficiency map are proposed. These strategies are attractive due to the relative simplicity of the real time implementation and the good performance. The strategies are tested both in a simulation environment and in an experimental setup using a 1.2-kW PEM fuel cell. The results, in terms of hydrogen consumption, are compared with an optimal case, which is assessed trough an advantageous technique also introduced in this work and with a pure fuel cell vehicle as well. This comparative reveals high efficiency and good performance, allowing to save up to 26% of hydrogen in urban scenarios. (author)

  19. A new strategy of axial power distribution control based on three axial offsets concept

    We have proposed a very simple control procedure for axial xenon oscillation control based on a characteristic trajectory. The trajectory is drawn by three offsets of power distributions, namely, AOp, AOi and AOx. They are defined as the offset of axial power distribution, the offset of the power distribution under which the current iodine distribution is obtained as the equilibrium and that for xenon distribution, respectively. When these offsets are plotted on X-Y plane for (AOp-AOx, AOi-AOx) the trajectory draws a quite characteristic ellipse (or an elliptic spiral). On the other hands, Constant Axial Offset Control (CAOC) procedure is adopted as axial power distribution control strategy during both base load and load following operations in domestic PWRs. In the previous paper, we have presented an innovative procedure of axial power distribution control during load following in PWRs based on this trajectory such that the AOp-AOx is to be controlled to zero when the value deviates the pre-determined limiting values. In this paper we propose a modified control strategy to get more stability of axial power distributions. In this strategy, we control the trajectory to be close to the major axis of the ellipse when the power distribution reaches the limiting values. In other words, the plot is not controlled only to reduce AOp-AOx but also AOi-AOx is taken into account at the same time. It is known that when the plot is controlled to the major axis, it means that the point gives the peak position of axial xenon oscillation. Therefore xenon oscillation will not increase its amplitude any more. Thus more stable axial power distribution control is attained. This kind of design concept is quite important especially for the future PWRs with elongated fuel length and longer core life. Because in a longer effective core and also the longer core life, it has been known that the stability of axial xenon oscillation becomes more unstable. In this paper, some simulation

  6. Setting objectives for community and systems change: an application of concept mapping for planning a statewide health improvement initiative.

    Trochim, William M K; Milstein, Bobby; Wood, Betty J; Jackson, Susan; Pressler, Virginia

    2004-01-01

    The Hawaii Department of Health (HDOH) used concept mapping techniques to engage local stakeholders and national subject area experts in defining the community and system factors that affect individuals' behaviors related to tobacco, nutrition, and physical activity. Over eight working days, project participants brainstormed 496 statements (edited to a final set of 90), which were then sorted and rated for their importance and feasibility. A sequence of multivariate statistical analyses, including multidimensional scaling and hierarchical cluster analysis, generated maps and figures that were then interpreted by project stakeholders. The results were immediately incorporated into an official plan, approved by the governor and state legislature, recommending how Hawaii's tobacco settlement resources could be used to create sustainable changes in population health. The results also provide empirical support for the premise that both community and systems factors ought to be considered when planning comprehensive health improvement initiatives. PMID:14965431

  7. An instantaneous optimization strategy based on efficiency maps for internal combustion engine/battery hybrid vehicles

    Highlights: • Instantaneous optimization method based on efficiency maps is proposed. • The energy sent to or supplied from the hybrid energy source is focused. • The efficiency of this energy is introduced as a new cost function to be maximized. • The results of our method are compared to that of DP, ECMS and MPC methods. • Our method provides competitive results with a lower computational load. - Abstract: This paper presents an instantaneous optimization algorithm based on the knowledge of the efficiency maps of the internal combustion engine (ICE) and the generator for the energy management system in hybrid electric vehicles. The proposed method formulates a new cost function representing the analytical expression of the overall energy efficiency of the hybrid energy source (i.e. ICE/generator set + battery pack) which is calculated based on the energy flow at the DC bus. Engine operating points are determined by assessing not only the efficiency map of the engine but also the efficiency map of the generator and the charge/discharge efficiency of the battery pack in order to maximize the efficiency of the energy delivered from the hybrid energy source to the drive system. The performance of the proposed method is analyzed and demonstrated on a hybrid electric bus developed in MATLAB/Simulink for different driving cycle conditions and the results have been compared with alternative optimization methods such as equivalent consumption minimization strategy (ECMS), model predictive control (MPC) and dynamic programming (DP) approach. The simulation results show that the proposed method provides a competitive performance with a lower computational burden compared to the alternative methods for different state of charge (SOC) ranges and drive cycle conditions

  8. Graded-threshold parametric response maps: towards a strategy for adaptive dose painting

    Purpose: To modify the single-threshold parametric response map (ST-PRM) method for predicting treatment outcomes in order to facilitate its use for guidance of adaptive dose painting in intensity-modulated radiotherapy. Methods: Multiple graded thresholds were used to extend the ST-PRM method (Nat. Med. 2009;15(5):572-576) such that the full functional change distribution within tumours could be represented with respect to multiple confidence interval estimates for functional changes in similar healthy tissue. The ST-PRM and graded-threshold PRM (GT-PRM) methods were applied to functional imaging scans of 5 patients treated for hepatocellular carcinoma. Pre and post-radiotherapy arterial blood flow maps (ABF) were generated from CT-perfusion scans of each patient. ABF maps were rigidly registered based on aligning tumour centres of mass. ST-PRM and GT-PRM analyses were then performed on overlapping tumour regions within the registered ABF maps. Main findings: The ST-PRMs contained many disconnected clusters of voxels classified as having a significant change in function. While this may be useful to predict treatment response, it may pose challenges for identifying boost volumes or for informing dose-painting by numbers strategies. The GT-PRMs included all of the same information as ST-PRMs but also visualized the full tumour functional change distribution. Heterogeneous clusters in the ST-PRMs often became more connected in the GT-PRMs by voxels with similar functional changes. Conclusions: GT-PRMs provided additional information which helped to visualize relationships between significant functional changes identified by ST-PRMs. This may enhance ST-PRM utility for guiding adaptive dose painting.

  9. Concept maps which visualise the artifice of teaching sequence: Cognition, linguistic and problem-based views on a common teaching problem

    David B. Hay

    2015-03-01

    Full Text Available This paper is concerned with the ways in which undergraduates are first introduced to Law of Contract in a University Law School. Concept mapping is used to document students’ changing understanding in the course of one first year undergraduate module. Forty seven students (the members of four tutorial groups made concept maps of “Law of Contract” at the start and at the finish of a twenty-four week study-programme and their maps were compared with two other concept maps made by their lecturer: 1 a map of the teaching sequence; 2 a map of the practices of Law of Contract. The analysis shows how the teaching sequence inscribes itself upon the students’ concept mapping structures even while this temporal pattern has little (or no genuine accord with the knowledge-shape of legal analysis. The paper explores two different approaches to concept map analysis: First the more traditional perspective of cognition (and cognitive-structure; second the “linguistic-turn”. Both of these highlight the “artifice of teaching sequence” but they locate this problem in different arenas. While the cognitive approach suggests that the problem is a general issue of student learning quality, the linguistic approach is more specific, suggesting that the problem is confined to the lesson planning which does not actually involve the students. This paper also concludes that while concept mapping shows the acquisition of a new vocabulary of legal concepts, the method itself is rather less useful for showing whether or not students are developing the skills of making judgement.

    Full Text Available The recent availability of the complete genome sequences of a large number of model organisms, together with the immense amount of data being produced by the new high-throughput technologies, means that we can now begin comparative analyses to understand the mechanisms involved in the evolution of the genome and their consequences in the study of biological systems. Phylogenetic approaches provide a unique conceptual framework for performing comparative analyses of all this data, for propagating information between different systems and for predicting or inferring new knowledge. As a result, phylogeny-based inference systems are now playing an increasingly important role in most areas of high throughput genomics, including studies of promoters (phylogenetic footprinting, interactomes (based on the presence and degree of conservation of interacting proteins, and in comparisons of transcriptomes or proteomes (phylogenetic proximity and co-regulation/co-expression. Here we review the recent developments aimed at making automatic, reliable phylogeny-based inference feasible in large-scale projects. We also discuss how evolutionary concepts and phylogeny-based inference strategies are now being exploited in order to understand the evolution and function of biological systems. Such advances will be fundamental for the success of the emerging disciplines of systems biology and synthetic biology, and will have wide-reaching effects in applied fields such as biotechnology, medicine and pharmacology.

    2011-10-01

    Full Text Available Abstract Background Work-related injuries result in considerable morbidity, as well as social and economic costs. Pain associated with these injuries is a complex, contested topic, and narcotic analgesics (NA remain important treatment options. Factors contributing to NA utilization patterns are poorly understood. This qualitative study sought to characterize the factors contributing to NA utilization amongst injured workers from the perspectives of physicians and pharmacists. Methods The study employed concept mapping methodology, a structured process yielding a conceptual framework of participants' views on a particular topic. A visual display of the ideas/concepts generated is produced. Eligible physicians and pharmacists (n = 22 serving injured workers in the province of Ontario (Canada were recruited via purposive sampling, and participated in concept mapping activities (consisting of brainstorming, sorting, rating, and map exploration. Participants identified factors influencing NA utilization, and sorted these factors into categories (clusters. Next, they rated the factors on two scales: 'strength of influence on NA over-utilization' and 'amenability to intervention'. During follow-up focus groups, participants refined the maps and discussed the findings and their implications. Results 82 factors were sorted into 7 clusters: addiction risks, psychosocial issues, social/work environment factors, systemic-third party factors, pharmacy-related factors, treatment problems, and physician factors. These clusters were grouped into 2 overarching categories/regions on the map: patient-level factors, and healthcare/compensation system-level factors. Participants rated NA over-utilization as most influenced by patient-level factors, while system-level factors were rated as most amenable to intervention. One system-level cluster was rated highly on both scales (treatment problems - e.g. poor continuity of care, poor interprofessional communication

    Full Text Available Abstract Background This article describes the development of a strategy to implement the insurance medicine guidelines for depression. Use of the guidelines is intended to result in more transparent and uniform assessment of claimants with depressive symptoms. Methods The implementation strategy was developed using the Intervention Mapping (IM method for alignment with insurance-medical practice. The ASE behavioural explanation model (Attitude, Social Influence and Self-Efficacy was used as theoretical basis for the development work. A literature study of implementation strategies and interviews with insurance physicians were performed to develop instruments for use with the guideline. These instruments were designed to match the needs and the working circumstances of insurance physicians. Performance indicators to measure the quality of the assessment and the adherence to the guidelines were defined with input from insurance physicians. Results This study resulted in the development of a training course to teach insurance physicians how to apply the guidelines for depression, using the aforementioned instruments. The efficacy of this training course will be evaluated in a Randomized Controlled Trial. Conclusions The use of IM made it possible to develop guideline support instruments tailored to insurance medical practice.

  16. Application of a concept development process to evaluate process layout designs using value stream mapping and simulation

    Ki-Young Jeong

    2011-07-01

    Full Text Available Purpose: We propose and demonstrate a concept development process (CDP as a framework to solve a value stream mapping (VSM related process layout design optimization problem.Design/methodology/approach: A case study approach was used to demonstrate the effectiveness of CDP framework in a portable fire extinguisher manufacturing company. To facilitate the CDP application, we proposed the system coupling level index (SCLI and simulation to evaluate the process layout design concepts.Findings: As part of the CDP framework application, three process layout design concepts - current layout (CL, express lane layout (ELL and independent zone layout (IZL - were generated. Then, the SCLI excluded CL and simulation selected IZL as the best concept. The simulation was also applied to optimize the performance of IZL in terms of the number of pallets. Based on this case study, we concluded that CDP framework worked well.Research limitations/implications: The process layout design optimization issue has not been well addressed in the VSM literature. We believe that this paper initiated the relevant discussion by showing the feasibility of CDP as a framework in this issue.Practical implications: The CDP and SCLI are very practice-oriented approaches in the sense that they do not require any complex analytical knowledge.Originality/value: We discussed a not well-addressed issue with a systematic framework. In addition, the SCLI presented was also unique.

  1. Mapping the Future of Environmental Health and Nursing: Strategies for Integrating National Competencies into Nursing Practice

    Larsson, Laura S.; Butterfield, Patricia

    2016-01-01

    Nurses are increasingly the primary contact for clients concerned about health problems related to their environment. In response to the need for nursing expertise in the field of environmental health, the Institute of Medicine (IOM), Agency for Toxic Substances and Disease Registry (ATSDR), and National Institute of Nursing Research (NINR) have designed core competencies for the nursing profession. The IOM competencies focus on four areas: (1) knowledge and concepts; (2) assessment and referral; advocacy, ethics, and risk communication; and (4) legislation and regulation. The competencies establish a baseline of knowledge and awareness in order for nurses to prevent and minimize health problems associated with exposure to environmental agents. To address the known difficulties of incorporating new priorities into established practice, nurses attending an environmental health short course participated in a nominal group process focusing on the question, “What specific actions can we take to bring environmental health into the mainstream of nursing practice?” This exercise was designed to bring the concepts of the national initiatives (IOM, NINR, ATSDR) to the awareness of individual nurses involved in the direct delivery of care. Results include 38 action items nurses identified as improving awareness and utilization of environmental health principles. The top five ideas were: (1) get environmental health listed as a requirement or competency in undergraduate nursing education; (2) improve working relationships with interdepartmental persons—a team approach; (3) strategically place students in essential organizations such as NIOSH, ATSDR, or CDC; (4) educate nurse educators; and (5) create environmental health awards in nursing. The 38 original ideas were also reorganized into a five-tiered conceptual model. The concepts of this model include: (1) developing partnerships; (2) strengthening publications; (3) enhancing continuing education; (4) updating nursing

  2. Mapping elements distribution in carapace of Caretta caretta: A strategy for biomonitoring contamination in sea turtles?

    Highlights: • We analyzed 11 elements in one carapace of Caretta caretta. • The distribution of the elements in carapace was studied. • Mapping elements as a strategy for biomonitoring contamination in sea turtles. • Some elements resulted representative for central and lateral areas of carapace. - Abstract: This study analyzed the carapace distribution of Ca, Cd, Cr, Cu, Mg, Mn, Pb, Sb, U, V and Zn by GF-AAS and ICP-AES in one specimen of Caretta caretta from Mediterranean Sea. Calcium, Mg, Mn, Pb, U, Zn were mainly distributed in the central area while Cd, Cr, Cu, Sb, V in lateral areas. Cadmium, Cr, Mg, Mn, Sb, U and V were different between lateral areas. The different distribution may be related to several exposures during lifetime and/or the shell ossification during growth. Carapace may be a suitable matrix for metal biomonitoring, however, further studies are required to confirm these findings

  4. Overview of superconductivity in Japan Strategy road map and R&D status

    Tsukamoto, O.

    2008-09-01

    Superconducting technology benefits society in broad fields; environment/energy, life science, manufacturing industry and information and communication. Superconducting equipments and devices used in various fields are divided into two categories, electric and electronic applications. Technologies in those applications are progressing remarkably owing to firm and consistent supports by various national projects. The final target of the NEDO R&D project of fundamental technology for superconductivity applications to develop 500 m long coated conductors (CCs) of the critical current 300 A/cm (at 77 K, 0 T) will be fulfilled by the end of JFY 2007 and manufacturing process to produce extremely low-cost CCs is to be developed to make the applications realistic. Preliminary works to develop power apparatuses using CCs have started in the frame of the R&D project for the fundamental technology and have produced significant results. Performance of BSCCO/Ag-sheathed wires has been improved greatly and various applications using those wires are being developed. R&D projects for SMES, power cable, flywheel energy storage and rotating machines are going to introduce those equipments to the real world. Technologies of SQUID and SFQ, basic devices of the electronic applications, are progressing dramatically also owing to various national projects. In this back ground the technology strategy map in the field of superconducting technology was formulated to prioritize investments in R&D by clearly defining the objectives and inspire autonomous R&D actives in various fields of industries. R&D activities in the superconducting technologies are to be scheduled following this strategy map.

  5. A new power mapping method based on ordinary kriging and determination of optimal detector location strategy

    Highlights: • A new power mapping method based on Ordinary Kriging (OK) is proposed. • Measurements from DayaBay Unit 1 PWR are used to verify the OK method. • The OK method performs better than the CECOR method. • An optimal neutron detector location strategy based on ordinary kriging and simulated annealing is proposed. - Abstract: The Ordinary Kriging (OK) method is presented that is designed for a core power mapping calculation of pressurized water reactors (PWRs). Measurements from DayaBay Unit 1 PWR are used to verify the accuracy of the OK method. The root mean square (RMS) reconstruction errors are kept at less than 0.35%, and the maximum reconstruction relative errors (RE) are kept at less than 1.02% for the entire operating cycle. The reconstructed assembly power distribution results show that the OK method is fit for core power distribution monitoring. The quality of power distribution obtained by the OK method is partly determined by the neutron detector locations, and the OK method is also applied to solve the optimal neutron detector location problem. The spatially averaged ordinary kriging variance (AOKV) is minimized using simulated annealing, and then, the optimal in-core neutron detector locations are obtained. The result shows that the current neutron detector location of DayaBay Unit 1 reactor is near-optimal

  8. A study on the effectiveness of investment strategy based on the concept of pivot points levels using Matthews criterion

    Antoni Wiliński

    2013-04-01

    Full Text Available In this work, the possibility of assessing traditional investment strategy based on the pivot points for using with other than the commonly used criterion is examined. The authors attempted to apply the Matthews Correlation Coefficient (further reffered as MCC criterion based on a confusion matrix when assessing the strategy to include more factors than the traditional criteria (such as profit, profit vs. Risk, Sharpe ratio, Calmar ratio and to express these factors by one number. The criterion based on a confusion matrix is, in authors beliefs, unique in this application and gives a fairly valuable estimation of trading strategy. An example of several strategies tested on EURUSD 1h time series in selected intervals in the years 2012-2013 is considered. Among these strategies there is a simple strategy based on the concept of pivot points levels and more complex derivative strategies, based on the vector of optimized values of certain parameters. These strategies are evaluated using both traditional criteria and modification of MCC proposed by the authors.

  10. Community perceptions of childbearing and use of safer conception strategies among HIV-discordant couples in Kisumu, Kenya

    Brooke T Breitnauer

    2015-06-01

    Full Text Available Introduction: Safer conception strategies (SCS have the potential to decrease HIV transmission among HIV-discordant couples who desire children. Community perceptions of SCS may influence the scale-up and uptake of these services, but little is known about how communities will react to these strategies. Without community support for SCS, their success as an HIV prevention tool may be limited. The objective of this study is to characterize community perceptions of SCS for HIV-discordant couples in Kisumu, Kenya, to inform ongoing and future safer conception intervention studies in low-resource settings. Methods: We conducted six focus group discussions and 11 in-depth-interviews in Kisumu, Kenya, among a diverse group (N=59 of community members, including men, women, youth (age 19–25, community health workers and local leaders. An iterative qualitative analysis using a grounded theory approach was employed. Results and discussion: All participants emphasized the importance of childbearing in their society and the right to have children, regardless of an individual's HIV status. While most participants believed that HIV-discordant couples should be allowed to have children, they discussed several barriers to the uptake of SCS such as HIV-related stigma, fear of HIV transmission to the uninfected partner and child, fear of unfamiliar medical procedures and lack of information among community members and health care providers about HIV prevention interventions that allow safer conception. Access to information, community experiences with successful safer conception interventions, healthcare provider training, male engagement and community mobilization may help overcome these barriers. Though assisted reproduction strategies generated the most negative reactions from participants, our results suggest that with education and explanation of these services, participants express interest in these strategies and want them to be offered in their

  11. Strategy for the mapping of interactive genes using bulked segregant analysis method and Mapmaker/Exp software

    WU Weiren; HUANG Biguang

    2006-01-01

    A qualitative trait is usually controlled by a single gene, but it may be sometimes controlled by two or even more genes. This phenomenon is called gene interaction. Rapidly searching for linked molecular markers via bulked segregant analysis (BSA)and then constructing regional linkage map with Mapmaker/Exp has become a common approach to mapping single major genes. However, methods and computer programs developed for mapping single major genes cannot be simply applied to interactive genes because the genetic patterns of gene interactions are quite different from that of single-gene inheritance. Up to now, experimental methods for quickly screening molecular markers linked to interactive genes and statistical methods and corresponding computer softwares for simultaneously analyzing the linkage relationships of multiple molecular markers to an interactive gene have not been available. To solve this problem, in this paper, we propose a strategy for mapping interactive genes using BSA and Mapmaker/Exp. We demonstrate that Mapmaker/Exp' strategy using F2 generation (in a few cases, F3 generation is also needed). As BSA and Mapmaker/Exp have been broadly used in gene mapping studies and are well known by many researchers, the strategies proposed in this paper will be useful for practical researches.

    Hart, Michael G; Ypma, Rolf J F; Romero-Garcia, Rafael; Price, Stephen J; Suckling, John

    2016-06-01

    Neuroanatomy has entered a new era, culminating in the search for the connectome, otherwise known as the brain's wiring diagram. While this approach has led to landmark discoveries in neuroscience, potential neurosurgical applications and collaborations have been lagging. In this article, the authors describe the ideas and concepts behind the connectome and its analysis with graph theory. Following this they then describe how to form a connectome using resting state functional MRI data as an example. Next they highlight selected insights into healthy brain function that have been derived from connectome analysis and illustrate how studies into normal development, cognitive function, and the effects of synthetic lesioning can be relevant to neurosurgery. Finally, they provide a précis of early applications of the connectome and related techniques to traumatic brain injury, functional neurosurgery, and neurooncology. PMID:26544769

    2012-04-01

    Full Text Available In an environment, which is highly competitive and everything changes rapidly, managers of organizations face with problems such as how to identify important factors preventing organizations from optimum use of available resources and capacities and invest more on key factors. To achieve this goal, we need to develop an effective strategy map for organizations. The strategy map is a constructional and expanding procedure to identify relationships among all the organization's strategic goals, which play a key role in achieving competitive advantage. Undoubtedly, representing a model to identify and to evaluate the important items for each of available goals in strategy map of each organization is a significant help for management to access higher competition benefits. In this paper, strategic objectives in the strategy map of one of the best producer of electric auto part makers in Iran called Electric Vehicle Co. East are evaluated based on balanced score card perspective and to assign appropriate values to available factors we use a hybrid method consist of AHP technique with Fuzzy logic.

  14. An alternative validation strategy for the Planck cluster catalogue and y-distortion maps

    Khatri, Rishi

    2016-07-01

    We present an all-sky map of the y-type distortion calculated from the full mission Planck High Frequency Instrument (HFI) data using the recently proposed approach to component separation, which is based on parametric model fitting and model selection. This simple model-selection approach enables us to distinguish between carbon monoxide (CO) line emission and y-type distortion, something that is not possible using the internal linear combination based methods. We create a mask to cover the regions of significant CO emission relying on the information in the χ2 map that was obtained when fitting for the y-distortion and CO emission to the lowest four HFI channels. We revisit the second Planck cluster catalogue and try to quantify the quality of the cluster candidates in an approach that is similar in spirit to Aghanim et al. (2015, A&A, 580, A138). We find that at least 93% of the clusters in the cosmology sample are free of CO contamination. We also find that 59% of unconfirmed candidates may have significant contamination from molecular clouds. We agree with Planck Collaboration XXVII (2016, A&A, in press) on the worst offenders. We suggest an alternative validation strategy of measuring and subtracting the CO emission from the Planck cluster candidates using radio telescopes, thus improving the reliability of the catalogue. Our CO mask and annotations to the Planck cluster catalogue, identifying cluster candidates with possible CO contamination, are made publicly available. The full Tables 1-3 are only available at the CDS via anonymous ftp to http://cdsarc.u-strasbg.fr (http://130.79.128.5) or via http://cdsarc.u-strasbg.fr/viz-bin/qcat?J/A+A/592/A48

  16. VERITAS: A Mission Concept for the High Resolution Topographic Mapping and Imaging of Venus

    Hensley, S.; Smrekar, S. E.; Pollard, B.

    2012-12-01

    Magellan, a NASA mission to Venus in the early 1990's, mapped nearly the entire surface of Venus with an S-band (12 cm) synthetic aperture radar and microwave radiometer and made radar altimeter measurements of the topography. These measurements revolutionized our understanding of the geomorphology, geology and geophysical processes that have shaped the evolution of the surface of Venus. The Magellan spacecraft had an elliptical orbit with an apoapsis of approximately 8000 km and a periapsis of 257 km and an orbital inclination of 86°. In this way the radar was able to collect long strips of data approximately 10000 km in length running north to south with altitudes varying from 3000 km to 257 km. During the remainder of the orbit the collected data was down linked to earth. The SAR mode operated in burst mode fashion whereby it transmitted a small string of pulses up to a couple of hundred pulses in length followed by a quiescent period when the radar ceased transmission and allowed interleaved operation of the altimeter and radiometer modes. This mode of operation allowed for a significant reduction in downlinked SAR imaging data at the expense of azimuth (i.e. along-track) resolution. However, the lack of finer resolution imagery and topography of the surface than that obtained by the Magellan mission has hampered the definitive answer to key questions concerning the processes and evolution of the surface of Venus. The Venus Emissivity, Radio Science, InSAR Topography And Spectroscopy (VERITAS) Mission is a proposed mission to Venus designed to obtain high resolution imagery and topography of the surface using an X-band radar configured as a single pass radar interferometer coupled with a multispectral NIR emissivity mapping capability. VERITAS would map surface topography with a spatial resolution of 250 m and 5 m vertical accuracy and generate radar imagery with 30 m spatial resolution. These capabilities represent an order of magnitude or better improvement

  17. Mapping Aboveground Biomass in the Amazon Basin: Exploring Sensors, Scales, and Strategies for Optimal Data Linkage

    Walker, W. S.; Baccini, A.

    2013-05-01

    Information on the distribution and density of carbon in tropical forests is critical to decision-making on a host of globally significant issues ranging from climate stabilization and biodiversity conservation to poverty reduction and human health. Encouraged by recent progress at both the international and jurisdictional levels on the design of incentive-based policy mechanisms to compensate tropical nations for maintaining their forests intact, governments throughout the tropics are moving with urgency to implement robust national and sub-national forest monitoring systems for operationally tracking and reporting on changes in forest cover and associated carbon stocks. Monitoring systems will be required to produce results that are accurate, consistent, complete, transparent, and comparable at sub-national to pantropical scales, and satellite-based remote sensing supported by field observations is widely-accepted as the most objective and cost-effective solution. The effectiveness of any system for large-area forest monitoring will necessarily depend on the capacity of current and near-future Earth observation satellites to provide information that meets the requirements of developing monitoring protocols. However, important questions remain regarding the role that spatially explicit maps of aboveground biomass and carbon can play in IPCC-compliant forest monitoring systems, with the majority of these questions stemming from doubts about the inherit sensitivity of satellite data to aboveground forest biomass, confusion about the relationship between accuracy and resolution, and a general lack of guidance on optimal strategies for linking field reference and remote sensing data sources. Here we demonstrate the ability of a state-of-the-art satellite radar sensor, the Japanese ALOS/PALSAR, and a venerable optical platform, Landsat 5, to support large-area mapping of aboveground tropical woody biomass across a 153,000-km2 region in the southwestern Amazon

  18. A comparison of policy and direct practice stakeholder perceptions of factors affecting evidence-based practice implementation using concept mapping

    Green Amy E

    2011-09-01

    Full Text Available Abstract Background The goal of this study was to assess potential differences between administrators/policymakers and those involved in direct practice regarding factors believed to be barriers or facilitating factors to evidence-based practice (EBP implementation in a large public mental health service system in the United States. Methods Participants included mental health system county officials, agency directors, program managers, clinical staff, administrative staff, and consumers. As part of concept mapping procedures, brainstorming groups were conducted with each target group to identify specific factors believed to be barriers or facilitating factors to EBP implementation in a large public mental health system. Statements were sorted by similarity and rated by each participant in regard to their perceived importance and changeability. Multidimensional scaling, cluster analysis, descriptive statistics and t-tests were used to analyze the data. Results A total of 105 statements were distilled into 14 clusters using concept-mapping procedures. Perceptions of importance of factors affecting EBP implementation varied between the two groups, with those involved in direct practice assigning significantly higher ratings to the importance of Clinical Perceptions and the impact of EBP implementation on clinical practice. Consistent with previous studies, financial concerns (costs, funding were rated among the most important and least likely to change by both groups. Conclusions EBP implementation is a complex process, and different stakeholders may hold different opinions regarding the relative importance of the impact of EBP implementation. Implementation efforts must include input from stakeholders at multiple levels to bring divergent and convergent perspectives to light.

  19. From printed geological maps to web-based service oriented data products - strategies, foundations and problems.

    Ebner, M.; Schiegl, M.; Stöckl, W.; Heger, H.

    2012-04-01

    The Geological Survey of Austria is legally obligated by the INSPIRE directive to provide data that fall under this directive (geology, mineral resources and natural risk zones) to the European commission in a semantically harmonized and technically interoperable way. Until recently the focus was entirely on the publication of high quality printed cartographic products. These have a complex (carto-)graphic data-model, which allows visualizing several thematic aspects, such as lithology, stratigraphy, tectonics, geologic age, mineral resources, mass movements, geomorphology etc. in a single planar map/product. Nonetheless these graphic data-models do not allow retrieving individual thematic aspects since these were coded in a complex portrayal scheme. Automatic information retrieval is thus impossible; and domain knowledge is necessary to interpret these "encrypted datasets". With INSPIRE becoming effective and a variety of conceptual models (e.g. GeoSciML), built around a semantic framework (i.e. controlled vocabularies), being available it is necessary to develop a strategy and workflow for semantic harmonization of such datasets. In this contribution we demonstrate the development of a multistage workflow which will allow us to transform our printed maps to semantically enabled datasets and services and discuss some prerequisites, foundations and problems. In a first step in our workflow we analyzed our maps and developed controlled vocabularies that describe the thematic content of our data. We then developed a physical data-model which we use to attribute our spatial data with thematic information from our controlled vocabularies to form core thematic data sets. This physical data model is geared towards use on an organizational level but builds upon existing standards (INSPIRE, GeoSciML) to allow transformation to international standards. In a final step we will develop a standardized mapping scheme to publish INSPIRE conformant services from our core datasets

  4. I. Concepts of Highly Excited Electronic Systems / II. Electronic Correlation Mapping from Finite to Extended Systems

    Berakdar, Jamal

    2006-02-01

    Knowledge of the excitation characteristics of matter is decisive for the descriptions of a variety of dynamical processes, which are of significant technological interest. E.g. transport properties and the optical response are controlled by the excitation spectrum. This self-contained work is a coherent presentation of the quantum theory of correlated few-particle excitations in electronic systems. It begins with a compact resume of the quantum mechanics of single particle excitations. Particular emphasis is put on Green function methods, which offer a natural tool to unravel the relations between the physics of small and large electronic systems. The book contains explicit expressions for the Coulomb Green function of two charge particles and a generalization to three-body systems. Techniques for the many-body Green function of finite systems are introduced and some explicit calculations of the Green functions are given. Concrete examples are provided and the theories are contrasted with experimental data, when available. A complimentary volume presents an up-to-date selection of applications of the developed concepts and a comparison with available experiments is made

  5. Mapping e-health strategies: thinking outside the traditional healthcare box.

    Wen, H Joseph; Tan, Joseph

    2005-01-01

    E-health has evolved and emerged in many forms; for instance, prescription refills, appointment scheduling, online billing, online medical records, and patient provider communications. Among other marketable e-health strategic applications, the use of e-health information has proliferated and has been presented in the form of content-only health gateways, physician directories, physician-only sites, and online pharmacies. The adoption of the web as an e-health medium has caused both traditional and e-healthcare providers to rethink and experiment with innovative ways of providing healthcare services. The e-providers who can effectively market themselves on the web will have a distinct advantage. At this time, a lot of education appears to be needed in this field in order to ensure that key players in this arena are contributing to the growth and success of e-health. In this paper, we present a general framework for mapping e-health strategies based on e-health business structures and their value proposition. Such e-health systems may be designed to meet the needs of e-stakeholders and for gaining competitive advantages. We believe that by opening up this line of discussion, it will provide future-orientated healthcare executives and entrepreneurs with useful insights into feasible e-health strategic solutions and their commercial potentials.

  6. What is needed to implement a computer-assisted health risk assessment tool? An exploratory concept mapping study

    Ahmad Farah

    2012-12-01

    Full Text Available Abstract Background Emerging eHealth tools could facilitate the delivery of comprehensive care in time-constrained clinical settings. One such tool is interactive computer-assisted health-risk assessments (HRA, which may improve provider-patient communication at the point of care, particularly for psychosocial health concerns, which remain under-detected in clinical encounters. The research team explored the perspectives of healthcare providers representing a variety of disciplines (physicians, nurses, social workers, allied staff regarding the factors required for implementation of an interactive HRA on psychosocial health. Methods The research team employed a semi-qualitative participatory method known as Concept Mapping, which involved three distinct phases. First, in face-to-face and online brainstorming sessions, participants responded to an open-ended central question: “What factors should be in place within your clinical setting to support an effective computer-assisted screening tool for psychosocial risks?” The brainstormed items were consolidated by the research team. Then, in face-to-face and online sorting sessions, participants grouped the items thematically as ‘it made sense to them’. Participants also rated each item on a 5-point scale for its ‘importance’ and ‘action feasibility’ over the ensuing six month period. The sorted and rated data was analyzed using multidimensional scaling and hierarchical cluster analyses which produced visual maps. In the third and final phase, the face-to-face Interpretation sessions, the concept maps were discussed and illuminated by participants collectively. Results Overall, 54 providers participated (emergency care 48%; primary care 52%. Participants brainstormed 196 items thought to be necessary for the implementation of an interactive HRA emphasizing psychosocial health. These were consolidated by the research team into 85 items. After sorting and rating, cluster analysis

  7. The use of active learning strategies in the instruction of Reactor Physics concepts

    Each of the Active Learning strategies employed to teach Reactor Physics material has been or promises to be instructionally successful. The Cooperative Group strategy has demonstrated a statistically significant increase in student performance on the unit exam in teaching conceptually difficult, transport and diffusion theory material. However, this result was achieved at the expense of a modest increase in class time. The Tutorial CBI programs have enabled learning equally as well as classroom lectures without the direct intervention of an instructor. Thus, the Tutorials have been successful as homework assignments, releasing classroom time for other instruction. However, the time required for development of these tools was large, on the order of two hundred hours per hour of instruction. The initial introduction of the Case-Based strategy was roughly as effective as the traditional classroom instruction. Case-Based learning could well, after important modifications, perform better than traditional instruction. A larger percentage of the students prefer active learning strategies than prefer traditional lecture presentations. Student preferences for the active strategies were particularly strong when they believed that the strategies helped them learn the material better than they would have by using a lecture format. In some cases, students also preferred the active strategies because they were different from traditional instruction, a change of pace. Some students preferred lectures to CBI instruction, primarily because the CBI did not afford them the opportunity to question the instructor during the presentation

  8. Designing concept maps for a precise and objective description of pharmaceutical innovations

    Iordatii Maia

    2013-01-01

    Full Text Available Abstract Background When a new drug is launched onto the market, information about the new manufactured product is contained in its monograph and evaluation report published by national drug agencies. Health professionals need to be able to determine rapidly and easily whether the new manufactured product is potentially useful for their practice. There is therefore a need to identify the best way to group together and visualize the main items of information describing the nature and potential impact of the new drug. The objective of this study was to identify these items of information and to bring them together in a model that could serve as the standard for presenting the main features of new manufactured product. Methods We developed a preliminary conceptual model of pharmaceutical innovations, based on the knowledge of the authors. We then refined this model, using a random sample of 40 new manufactured drugs recently approved by the national drug regulatory authorities in France and covering a broad spectrum of innovations and therapeutic areas. Finally, we used another sample of 20 new manufactured drugs to determine whether the model was sufficiently comprehensive. Results The results of our modeling led to three sub models described as conceptual maps representingi the medical context for use of the new drug (indications, type of effect, therapeutical arsenal for the same indications, ii the nature of the novelty of the new drug (new molecule, new mechanism of action, new combination, new dosage, etc., and iii the impact of the drug in terms of efficacy, safety and ease of use, compared with other drugs with the same indications. Conclusions Our model can help to standardize information about new drugs released onto the market. It is potentially useful to the pharmaceutical industry, medical journals, editors of drug databases and medical software, and national or international drug regulation agencies, as a means of describing the main

    Due to the multi-dimensional characteristics of professionalism, no single assessment modality has shown to reliably assess professionalism. This review aims to describe some of the popular assessment tools that are being used to assess professionalism with a view to formulate a framework of assessment of professionalism in medicine. In December 2015, the online research databases of MEDLINE, the Educational Resources Information Center (ERIC), Elton Bryson Stephens Company (EBSCO), SCOPUS, OVID and PsychINFO were searched for full-text English language articles published during 2000 to 2015. MeSH terms "professionalism" AND "duty" AND "assessment" OR "professionalism behavioural" AND "professionalism-cognitive" were used. The research articles that assessed professionalism across medical fields along with other areas of competencies were included. A final list of 35 articles were selected for this review. Several assessment tools are available for assessing professionalism that includes, but not limited to, mini clinical evaluation exercise, standardised direct observation of procedural skills, professionalism mini-evaluation exercise, multi-source feedback and 360 degree evaluation, and case based discussions. Because professionalism is a complex construct, it is less likely that a single assessment strategy will adequately measure it. Since every single assessment tool has its own weaknesses, triangulation involving multiple tools can compensate the shortcomings associated with any single approach. Assessment of professionalism necessitates a combination of modalities at individual, interpersonal, societal, and institutional levels and should be accompanied by feedback and motivational reflection that will, in turn, lead to behaviour and identity formation. The assessment of professionalism in medicine should meet the criteria of validity, reliability, feasibility and acceptability. Educators are urged to enhance the depth and quality of assessment instruments

  11. Creative Clusters in the Czech Republic—Strategy for Local Development or Fashionable Concept?

    Marková Blanka

    2014-07-01

    Full Text Available In an era of globalization and increasing competition among cities, creative industries are gaining greater attention as a catalyst for local and regional development. This is reflected in the theory of Richard Florida, which was accepted after 2002 by professionals in the field of urban planning, especially in North America and Western Europe, but critically analyzed by the academic community in the field of urban and regional development for its insufficient empirical evidence. Creative industries might be fostered through clusters that are widely accepted as concepts for improving the economic efficiency of regions. This paper introduces the concept of creative clusters into discussions by Czech geographers, while analysing the pioneer projectled development of an Audiovisual Cluster in the Zlín Region, and the possible transfer of the creative clusters concept to other Czech regions.

  20. THE CONCEPT OF PUBLIC DEBT MANAGEMENT STRATEGY OF THE REPUBLIC OF CROATIA

    Domagoj Karačić

    2015-12-01

    Full Text Available This paper attempts to answer the question whether transparent and timely preparation of the Public Debt Management Strategy of the Republic of Croatia can improve the quality of management of public debt in Croatia, and with that, if it can affect the quality of budget policy in general. The terms public debt management and debt management strategy are not new in the professional and scientific literature. Certain suggestions and solutions already exist, but failed to be implemented. Deadlines for the preparation, as well as the content of the public debt management strategy, are not legally regulated. As a result, only two strategies have been prepared so far, and only one has met the defined standards. Furthermore, PDMS for the current period does not exist, and it is questionable by which guidelines public debt management in Croatia has been carried out. The paper is composed of two parts. The first part shows the theoretical overview and analysis of the current state of public debt in the Republic of Croatia. The second part deals with the theoretical guidelines and quality analysis of previous versions of PDMS.

  2. Testing communication strategies to convey genomic concepts using virtual reality technology.

    Kaphingst, Kimberly A; Persky, Susan; McCall, Cade; Lachance, Christina; Beall, Andrew C; Blascovich, Jim

    2009-06-01

    Health professionals need to be able to communicate information about genomic susceptibility in understandable and usable ways, but substantial challenges are involved. We developed four learning modules that varied along two factors: (1) learning mode (active learning vs. didactic learning) and (2) metaphor (risk elevator vs. bridge) and tested them using a 2 x 2 between-subjects, repeated measures design. The study used an innovative virtual reality technology experimental platform; four virtual worlds were designed to convey the concept that genetic and behavioral factors interact to affect common disease risk. The primary outcome was comprehension (recall, transfer). Study participants were 42 undergraduates aged 19-23. The results indicated that the elevator metaphor better supported learning of the concept than the bridge metaphor. Mean transfer score was significantly higher for the elevator metaphor (p didactic learning than active learning (p didactic learning in increasing comprehension of health information. The findings also indicated that less complex metaphors might convey abstract concepts more effectively. PMID:19466649

  3. A complex geo-scientific strategy for landslide hazard mitigation ─ from airborne mapping to ground monitoring

    2008-01-01

    Full Text Available After a large landslide event in Sibratsgfäll/Austria several exploration methods were evaluated on their applicability to investigate and monitor landslide areas. The resulting optimised strategy consists of the combined application of airborne electromagnetics, ground geoelectrical measurements and geoelectrical monitoring combined with hydrological and geological mapping and geotechnical modelling. Interdisciplinary communication and discussion was the primary key to assess this complicated hazard situation.

  4. Validation of RCS depressurization strategy and core coolability map for independent scenarios of SBLOCA, SBO, and TLOFW

    Severe accident analysis for Small Break (SB), Middle Break (MB), and Large Break (LB) Loss-Of-Coolant Accident (LOCA), Station Black Out (SBO), Total Loss-Of-Feed-Water (TLOFW) was performed and effectiveness of Reactor Coolant System (RCS) depressurization strategies of OPR1000 was analyzed using MELCOR 1.8.6 code. Required injection flow rate has been derived using Core Exit Temperature (CET) information obtained from MELCOR calculation and a simple model and corresponding coolability map have been suggested to assist effective operator action. The depressurization strategies using secondary Atmospheric Dump Valve (ADV) for SBLOCA, pressurizer Safety Depressurization System (SDS) for SBO and TLOFW were introduced in 5 min since the initiation of Severe Accident Management Guidance (SAMG). Respective mitigation strategy employed leads to significant delay of the reactor pressure vessel failure and RCS pressure at Reactor Pressure Vessel (RPV) failure was lower than the SAMG target pressure of 2.86 MPa. Thus, possibility of High Pressure Melt Ejection (HPME) and impair of containment building is expected to avoid effectively. Using CET information obtained from MELCOR calculation, a simple model and a coolability map for the required injection flow rate were developed for recovery of core coolability. It is suggested that the coolability map based on MELCOR calculation results may provide decisive and intuitive information to operators for more effective safety management. (author)

    Christos Anagnostopoulos

    2015-04-01

    Full Text Available This study uses Leximancer (a text-mining tool for visualizing the structure of concepts and themes in text to map the published research within Sports Management International Journal Choregia from 2005 to 2014. Drawing on 88 papers, of which 61 were classified as empirical and 27 as non-empirical ones, results reveal that the last half of the examined period concerned works that do not relate to the Greek context, which has been the case during the first years of Choregia’s publication. ‘Sports participation’, ‘physical activity’, ‘Greek football clubs’ – all largely associated with ‘management’ and ‘factors’ – shape the main themes in the studies published within Choregia. In addition, an emphasis on positivistic approaches, through the employment of questionnaires and utilizing students as the population for data collection, appears to be the dominant methodological orientation of the published content in Choregia. Becoming the platform for studies that originate beyond the American, Greek, and Iranian contexts, through special issues and invited contributions in the form of research notes would potentially increase this outlet’s scope and depth (that is, context and themes, respectively.

  10. Long-term interim storage concepts with conditioning strategies ensuring compatibility with subsequent disposal or reprocessing

    The objective of the CEA studies carried out under research topic 3 (long-term interim storage) of the 1991 French radioactive waste management law is to demonstrate the industrial feasibility of a comprehensive, flexible interim storage facility by thoroughly evaluating and comparing all the basic components of various interim storage concepts. In this context, the CEA is considering reference solutions or concepts based on three primary components (the package, the interim storage facility and the site) suitable for determining the specifications of a very long-term solution. Some aspects are examined in greater detail, such as the implementation of long-term technologies, conditioning processes ensuring the absence of water and contamination in the facility, or allowance for radioactive decay of the packages. The results obtained are continually compiled in reports substantiating the design options. These studies should also lead to an overall economic assessment in terms of the capital and operating cost requirements, thereby providing an additional basis for selecting the design options. The comparison with existing industrial facilities highlights the technical and economic progress represented by the new generation of interim storage units. (authors)

    2015-07-01

    In Austria the set up of radon maps is required already since 1992 in the recommendation of the radiation protection commission and stated in the radiation protection law since 2004. In the framework of the Austrian National Radon Project (OENRAP) indoor radon measurements were carried out in about 9000 dwellings from 1992 to 2002, a radon potential was calculated for all municipalities and displayed in a radon potential map. This map is basis for decisions e.g. for preventive measures. According to the new European basic safety standards (EU-BSS) member states shall identify ''radon areas'', relevant e.g. for mandatory radon measurements at work places. The identification of such areas will impact several (legal) decisions and future measures. In course of the implementation of the EU-BSS the radon map of Austria should be improved and optimized for its purpose. As a first step indoor radon measurements were carried out in dwellings in municipalities detected to be ''outliers'' compared to neighboring municipalities. In addition a new indoor radon survey was designed and started, funded by the BMLFUW, with radon measurements in dwellings of members of the voluntary fire brigades, selected by defined criteria. As a pilot study measurements in about 6500 dwellings were carried out in Upper Austria from June 2014 to February 2015. Based on the results of the pilot study and an international radon mapping workshop held in Vienna in January 2015 possible methods for radon mapping in Austria will be tested and discussed. In this contribution the strategies, methods, first results and findings on the way to a new Austrian radon map will be presented.

    The snow cover plays an important role in the hydrological cycle of Quebec (Eastern Canada). Consequently, evaluating its spatial extent interests the authorities responsible for the management of water resources, especially hydropower companies. The main objective of this study is the development of a snow-cover mapping strategy using remote sensing data and ensemble based systems techniques. Planned to be tested in a near real-time operational mode, this snow-cover mapping strategy has the advantage to provide the probability of a pixel to be snow covered and its uncertainty. Ensemble systems are made of two key components. First, a method is needed to build an ensemble of classifiers that is diverse as much as possible. Second, an approach is required to combine the outputs of individual classifiers that make up the ensemble in such a way that correct decisions are amplified, and incorrect ones are cancelled out. In this study, we demonstrate the potential of ensemble systems to snow-cover mapping using remote sensing data. The chosen classifier is a sequential thresholds algorithm using NOAA-AVHRR data adapted to conditions over Eastern Canada. Its special feature is the use of a combination of six sequential thresholds varying according to the day in the winter season. Two versions of the snow-cover mapping algorithm have been developed: one is specific for autumn (from October 1st to December 31st) and the other for spring (from March 16th to May 31st). In order to build the ensemble based system, different versions of the algorithm are created by varying randomly its parameters. One hundred of the versions are included in the ensemble. The probability of a pixel to be snow, no-snow or cloud covered corresponds to the amount of votes the pixel has been classified as such by all classifiers. The overall performance of ensemble based mapping is compared to the overall performance of the chosen classifier, and also with ground observations at meteorological

    Calibrating the photometric redshifts of >10^9 galaxies for upcoming weak lensing cosmology experiments is a major challenge for the astrophysics community. The path to obtaining the required spectroscopic redshifts for training and calibration is daunting, given the anticipated depths of the surveys and the difficulty in obtaining secure redshifts for some faint galaxy populations. Here we present an analysis of the problem based on the self-organizing map, a method of mapping the distribution of data in a high-dimensional space and projecting it onto a lower-dimensional representation. We apply this method to existing photometric data from the COSMOS survey selected to approximate the anticipated Euclid weak lensing sample, enabling us to robustly map the empirical distribution of galaxies in the multidimensional color space defined by the expected Euclid filters. Mapping this multicolor distribution lets us determine where - in galaxy color space - redshifts from current spectroscopic surveys exist and whe...

    Schork, N J; Boehnke, M.; Terwilliger, J D; Ott, J.

    1993-01-01

    Recent advances in molecular biology have provided geneticists with ever-increasing numbers of highly polymorphic genetic markers that have made possible linkage mapping of loci responsible for many human diseases. However, nearly all diseases mapped to date follow clear Mendelian, single-locus segregation patterns. In contrast, many common familial diseases such as diabetes, psoriasis, several forms of cancer, and schizophrenia are familial and appear to have a genetic component but do not e...

  4. Brazilian Constitution: The concept of family and family planning as a government strategy

    Helena Beatriz Kochenborger Scarparo

    2015-07-01

    Full Text Available In this paper we approached a study about the legal contexts of the Brazilian Constitution which we find the notion of family and family planning, as well as the laws regarding family planning that were promulgated after the 1988 Constitution. Guided through the Foucault’s perspective we questioning how the rationalities that underlie such legislations may produce effects in the organization and management of the population nowadays. We selected the material analyzed through systematic research in the Brazilian Constitution and in the Portal of Legislation of the Presidency of Brazil. The results obtained indicate that the idea of family and family planning compose legal tools which constitute elements of retrenchment and disciplining of subjects by regulations that they establish. Thus, the jurisdictions operate as strategies to the Brazilian government that include goals that put the employment as the base of everything, and from this, directs people through the policies that produce.

  5. Agent-based Cyber Control Strategy Design for Resilient Control Systems: Concepts, Architecture and Methodologies

    Craig Rieger; Milos Manic; Miles McQueen

    2012-08-01

    The implementation of automated regulatory control has been around since the middle of the last century through analog means. It has allowed engineers to operate the plant more consistently by focusing on overall operations and settings instead of individual monitoring of local instruments (inside and outside of a control room). A similar approach is proposed for cyber security, where current border-protection designs have been inherited from information technology developments that lack consideration of the high-reliability, high consequence nature of industrial control systems. Instead of an independent development, however, an integrated approach is taken to develop a holistic understanding of performance. This performance takes shape inside a multiagent design, which provides a notional context to model highly decentralized and complex industrial process control systems, the nervous system of critical infrastructure. The resulting strategy will provide a framework for researching solutions to security and unrecognized interdependency concerns with industrial control systems.

  6. The recharge area concept: A strategy for siting nuclear waste repositories

    The Recharge Area Concept is the proposition that in Canadian-Shield type natural environments recharge areas of regional groundwater flow systems are superior for high-level nuclear waste repositories to other types of groundwater flow regimes, especially to areas of groundwater discharge. This conclusion is reached from an analysis of basinal groundwater flow models. The calculations were made for a two-dimensional flank of a fully saturated topographic basin, 20 km long and 4 km deep, in which groundwater is driven by gravity. Variants of hydraulic-conductivity distributions were considered: 1) homogeneous; 2) stratified; and 3) stratified-faulted. The faults attitudes were changed by steps from vertical to horizontal for different variants. The model is assumed conceptually to represent the crystalline-rock environment of the Canadian Shield. The hydrogeologic performances of hypothetical repositories placed 500 m deep in the recharge and discharge areas were characterized by thirteen parameters. The principal advantages of recharge- over discharge-area locations are: 1) longer travel paths and return-flow times from repository to surface; 2) robustness of predicted values of performance parameters; 3) field-verifiability of favourable hydrogeologic conditions (amounting to an implicit validation of the calculated minimum values of return-flow times); 4) site acceptance based on quantifiable and observable flow-controlling parameters; and 5) simple logistics and favourable economics of site selection and screening. As a by-product of modeling, it is demonstrated that the presence of old water is not an indication of stagnancy. (author)

    Even if we succeed in achieving the EU target of reducing global warming to 2 C, it will be absolutely essential to adapt to changing climatic conditions. The greenhouse gases currently present in the atmosphere will influence the climate in coming decades. The day on which it is quite clear which climatic scenario prevails, so that it is possible to model all relevant processes down to regional level, will be the day on which it is too late to adapt to the actual scenario. Our endeavours to adapt to climate change do not mean, however, that we can neglect to take measures in order to reduce the output of greenhouse gases. It is important to remember that on their own, neither adaptation nor mitigation can prevent the grave impacts resulting from climate change. In fact, they complement each other meaningfully thus helping to alleviate the risks of climate change. On 17th December 2008 the German Federal Cabinet adopted the DAS (German Strategy for the Adaptation to Climate Change), (Bundesregierung 2008). The DAS has created the framework for adapting to the consequences of climate change in Germany. First and fore-most, the DAS contributes its guidelines at Federal level, to provide a guideline for agents at other levels. The Strategy lays the foundation for a medium-term process. In conjunction with the individual Federal States and other groups representing various sectors of society, the Strategy provides a step-by-step assessment of the risks of climate change. Furthermore, it states the potential requirements for action, and defines the appropriate goals and potential adaptation measures to be developed and implemented in this process. In due course, the Federal Environment Agency (UBA) will design a comprehensive set of tools to support and advance the DAS. An integral part of this will be the Special Information System 'Adaptation' (FISKA) and an Indicator System to aid adaptation. The latter is one of the key tasks identified for the DAS. As far

  9. 'Catch them young strategy' for the ethical education on radiation technology: A concept of 7 'Es'

    It is the ethics which makes human to make the justifiable use of radiation; there are always two sides of coin; the benefits in the use of ionising radiation and radionuclide should weigh with the risk. Radiation technology has both, the advantages and disadvantages with certain shortcomings; however abandonment of any technology at this juncture may be threat to human civilization. There should always be a rapid evolving process in the development of technology-and so in radiation techniques for the sustenance of human welfare. Hence a ''strategy'' is intended to be proposed and formulated through this Conference; some in-depth and deep rooted engravings on the young minds are proposed which are going to be the part of an enlightened citizens and policy makers of tomorrow who could justifiably implement the right and better use of radiation technology. Thus nowhere it could be taken as the liberal use of double-edged sword. The proposed strategy in the presentation will emphasize on educational policy from light learning activities in the classroom to a short term and long-lasting impact for the young children through planned lessons which could make a mind-etching luminous part of their curriculum. Ethics is an engrave on the minds which are formed after prolonged exposure of stimuli to brain through receptor organs by various ways like by a regular 'dinner table chats', company chat on playground' and 'off-hour chat by teacher' or by self-experience. Radiation education leading to ethics certainly can not be by self-experiences - however the narration, pictures and movies on some of incidences like that of Hiroshima and Nagasaki should be very often and religiously given and shown to them world wide. An impressive and sugar-coated' informal ways of radiation education is needed. The principle of 7 Es i.e. how exposure to experiences, education, enrichment of knowledge, elimination of fear and engravings in mind lead to ethics for radiation which will give us

Mapping this multicolor distribution lets us determine where—in galaxy color space—redshifts from current spectroscopic surveys exist and where they are systematically missing. Crucially, the method lets us determine whether a spectroscopic training sample is representative of the full photometric space occupied by the galaxies in a survey. We explore optimal sampling techniques and estimate the additional spectroscopy needed to map out the color–redshift relation, finding that sampling the galaxy distribution in color space in a systematic way can efficiently meet the calibration requirements. While the analysis presented here focuses on the Euclid survey, similar analysis can be applied to other surveys facing the same calibration challenge, such as DES, LSST, and WFIRST.

  12. Terrorist profiling as a Counterinsurgency Strategy: Applying the Concept to Law Enforcement

    Farhan Hyder Sahito

    2013-10-01

    Full Text Available The nature of terrorism is fundamentally psychological. Similarly, psychological profiling is widely accepted in detecting crimes in both law enforcement operations and the study of criminology. However, there is a need to transfer its appearance from old traditional criminal environment to the context of counterterrorism. This research argues that most prevalent method of interrogating suspects to achieve distinction between guilty and innocent is to establish a set of psychological attributes and factors. This paper proposes that terrorist's profiling is value-added intelligence that may add a new dimension in counterterrorism to identify the individual behind a terrorist act. It is important to constructs a terrorist profile before designing a paradigm that should determine the probability of terroristic trends within the individual as well as certain perceptible qualities with which an observed suspect can be likened to. This article proposes a personality-guided model of interrogation with different categories to steer clear of oversimplified thinking about individual terrorist or groups. The objective is to adapt the style and content of questioning to obtain a clear overall picture of the suspect's knowledge with appropriate interviewing and interrogation methods. This profiling will provide thorough understanding of the ideology that drives terrorism and more awareness of the likely means and likely targets used by terrorists. This paper is a shift in direction – focusing rather on the development of evidence-based methods that could lead to an effective counterinsurgency strategy and the extraction of innocent's involvement in the terrorism.

  13. Developing An Effective Strategy to Configure Assembly Systems Using Lean Concepts

    2010-12-01

    Full Text Available The manufacturing industry has been pushed to adopt more effective production strategies to meet the challenges of shorter life cycle, higher quality, lower cost and wider variety of customer demands. This increased emphasis on achieving highly adaptive manufacturing with reduction in manufacturing costs and better utilization of manufacturing resources force to implementing new and efficient management techniques in their manufacturing operations. Some of the established tools in this context are lean practices. In manufacturing, assembly is one of the major activities that combine the machined components into final product. Decision on appropriate facility layout and viable assembly sequence (line balancing adaptable to takt time requirement with cost benefit is a challenging task. This paper proposes an integrated cost model for a typical assembly process to determine cost per part more precisely by considering seven types of "contributing factors". This procedure is performed under different takt time conditions to configure the assembly system in terms of cost per piece and to decide the adaptable layout. A prototype assembly system is established in this research to demonstrate the effectiveness of the cost model. The results show that there are significant variations in cost per piece with respect to changes in layout configurations and takt time.

    1997-01-01

    This paper describes a uniform method for calculating the interpolation of scalp EEG potential distribution, the current source density (CSD), the cortical potential distribution (cortical mapping) and the CSD of the cortical potential distribution. It will be shown that interpolation and deblurring methods such as CSD or cortical mapping are not independent of the inverse problem in potential theory. Not only the resolution but also the accuracy of these techniques, especially those of deblurring, depend greatly on the spatial sampling rate (i.e., the number of electrodes). Using examples from simulated and real (64 channels) data it can be shown that the application of more than 100 EEG channels is not only favourable but necessary to guarantee a reasonable accuracy in the calculations of CSD or cortical mapping. Likewise, it can be shown that using more than 250 electrodes does not improve the resolution. PMID:9104831

  15. Strategies for mapping synaptic inputs on dendrites in vivo by combining two-photon microscopy, sharp intracellular recording and pharmacology

    Manuel eLevy

    2012-12-01

    Full Text Available Uncovering the functional properties of individual synaptic inputs on single neurons is critical for understanding the computational role of synapses and dendrites. Previous studies combined whole-cell patch recording to load neurons with a fluorescent calcium indicator and two-photon imaging to map subcellular changes in fluorescence upon sensory stimulation. By hyperpolarizing the neuron below spike threshold, the patch electrode ensured that changes in fluorescence associated with synaptic events were isolated from those caused by back-propagating action potentials. This technique holds promise for determining whether the existence of unique cortical feature maps across different species may be associated with distinct wiring diagrams. However, the use of whole-cell patch for mapping inputs on dendrites is challenging in large mammals, due to brain pulsations and the accumulation of fluorescent dye in the extracellular milieu. Alternatively, sharp intracellular electrodes have been used to label neurons with fluorescent dyes, but the current passing capabilities of these high impedance electrodes may be insufficient to prevent spiking. In this study, we tested whether sharp electrode recording is suitable for mapping functional inputs on dendrites in the cat visual cortex. We compared three different strategies for suppressing visually evoked spikes: (1 hyperpolarization by intracellular current injection, (2 pharmacological blockade of voltage-gated sodium channels by intracellular QX-314, and (3 GABA iontophoresis from a perisomatic electrode glued to the intracellular electrode. We found that functional inputs on dendrites could be successfully imaged using all three strategies. However, the best method for preventing spikes was GABA iontophoresis with low currents (5 to 10 nA, which minimally affected the local circuit. Our methods advance the possibility of determining functional connectivity in preparations where whole-cell patch may be

  16. Maintenance strategies and safety on a deregulated market. Mapping of changes in maintenance strategies and their possible consequences

    The overall purpose of the project was to make a survey of the changes in the Swedish nuclear power plants over the last five years. There is a risk that nuclear power companies after a deregulation will focus especially on reducing operation and maintenance costs and that the changes could have a negative effect on the reactor safety. The task has involved summarising the actual changes, describing the present situation, the need for future development and the differences between the plants as well as identifying possible reactor safety related risks. The survey has been carried out in a broad perspective, studying the changes in equipment, maintenance strategies and the work situation of the staff. Three case studies were carried out at the Swedish nuclear power plants. Documentation from the companies has been analysed and a selection of in total 27 'informed' employees in different positions have been interviewed in total. The project also included a fourth case study concerning railway traffic. This branch of business is interesting because of its longer experience on a deregulated and competitive market. Conclusions concerning the companies individually as well as similarities and differences between them are presented in this report. Results: There have been more changes both in strategy and organisation in the last five years than during the preceding 5-10-year-period and the pace has been relatively rapid. The deregulation of the electricity market was implemented January 1997 and became the main motive force for the changes. The staffing has been reduced or unchanged and the work demands have increased. The maintenance skills have been redistributed within the organisation. New methods and equipment, i.e. RCM, and programmable systems make increased demands for analytical and theoretical competence. In the short term, job satisfaction and motivation have in some cases been negatively influenced by the new organisation forms, according to several of the

    1999-10-01

    Representatives of the Department of Energy, the national laboratories, the Waste Isolation Pilot Plant (WIPP), and others gathered to initiate the development of broad-based concepts and strategies for transparency monitoring of nuclear materials at the back end of the fuel/weapons cycle, including both geologic disposal and monitored retrievable storage. The workshop focused on two key questions: ''Why should we monitor?'' and ''What should we monitor?'' These questions were addressed by identifying the range of potential stakeholders, concerns that stakeholders may have, and the information needed to address those concerns. The group constructed a strategic framework for repository transparency implementation, organized around the issues of safety (both operational and environmental), diversion (assuring legitimate use and security), and viability (both political and economic). Potential concerns of the international community were recognized as the possibility of material diversion, the multinational impacts of potential radionuclide releases, and public and political perceptions of unsafe repositories. The workshop participants also identified potential roles that the WIPP may play as a monitoring technology development and demonstration test-bed facility. Concepts for WIPP'S potential test-bed role include serving as (1) an international monitoring technology and development testing facility, (2) an international demonstration facility, and (3) an education and technology exchange center on repository transparency technologies.

    One of the most technically challenging activities of the IFMIF facility is the maintenance and the refurbishment of its components, and among these the target system appears to be critical since it is located in the most severe region of neutron irradiation (60 dpa/fpy). Two different target assembly systems have been developed: the first is known as integral target while the second one is based on the so called replaceable backplate bayonet concept. The present remote handling (RH) procedures developed for the refurbishment of the removable backplate foresee the removal of all the components from the upper part of the test cell. This operation has a strong impact on the intervention time for the backplate refurbishment which has to be repeated at least every year. Consequently the need to update the RH strategy for the refurbishment of this component becomes a precondition in order to fulfill the stringent requirement to enhance the duty cycle of IFMIF plant. In this paper two potential approaches are presented: the first relies on the possibility to perform all the refurbishment operations in situ in the test cell cavern, whilst the second one foresees to perform these operations off-line in a hot cell. Advantages and disadvantages of these approaches together with the RH requirements for the refurbishment operations of the backplate bayonet concepts are also reported.

  20. Evolutionary pressure on reproductive strategies in flatfish and groundfish: Relevant concepts and methodological advancements

    Kjesbu, O. S.; Witthames, P. R.

    2007-07-01

    Flatfish and groundfish show many similarities in reproductive strategies and tactics, both in types present and in responses to fishing pressure or changes in their environment. Over the last 20-30 years the reproduction of Atlantic cod Gadus morhua, Atlantic halibut Hippoglossus hippoglossus, plaice Pleuronectes platessa, sole Solea solea, and turbot Scophthalmus maximus have been extensively studied in the North Atlantic. For cod, halibut and turbot, the research has progressed rapidly due to interest from the aquaculture industry. Extensive overexploitation over many years in combination with climate change represents a potential evolutionary pressure towards changes in growth, lower age at maturity, increased fecundity, smaller egg size (and thereby larval size) and change in spawning time. Early sexual maturity/precocious maturation is also seen in aquaculture and is problematic economically due to a reduction in fillet production. In this paper information is reviewed from studies on both wild and captive populations in experiments, the latter considered important because overexploitation, such as observed in the North Sea, often reduces the natural dynamics in growth and reproduction and complicates collection of sufficiently large samples. Evidence from laboratory experiments demonstrates the inherent plasticity of fecundity production and how this is controlled by food availability and length of photoperiod, while recent information from field studies demonstrates the evolution of genotypes in response to fishing mortality. Today several laboratories have adopted modern techniques for analysis of reproductive investments (fecundity, atresia and sperm characterisation) in controlled experimental situations to explore the effect of temperature or other environmental parameters (such as salinity) on reproduction. These developments, in combination with the rapid implementation of molecular techniques, should make it possible in the future to present highly

  1. Nonisocentric Treatment Strategy for Breast Radiation Therapy: A Proof of Concept Study

    Purpose: To propose a nonisocentric treatment strategy as a special form of station parameter optimized radiation therapy, to improve sparing of critical structures while preserving target coverage in breast radiation therapy. Methods and Materials: To minimize the volume of exposed lung and heart in breast irradiation, we propose a novel nonisocentric treatment scheme by strategically placing nonconverging beams with multiple isocenters. As its name suggests, the central axes of these beams do not intersect at a single isocenter as in conventional breast treatment planning. Rather, the isocenter locations and beam directions are carefully selected, in that each beam is only responsible for a certain subvolume of the target, so as to minimize the volume of irradiated normal tissue. When put together, the beams will provide an adequate coverage of the target and expose only a minimal amount of normal tissue to radiation. We apply the nonisocentric planning technique to 2 previously treated clinical cases (breast and chest wall). Results: The proposed nonisocentric technique substantially improved sparing of the ipsilateral lung. Compared with conventional isocentric plans using 2 tangential beams, the mean lung dose was reduced by 38% and 50% using the proposed technique, and the volume of the ipsilateral lung receiving ≥20 Gy was reduced by a factor of approximately 2 and 3 for the breast and chest wall cases, respectively. The improvement in lung sparing is even greater compared with volumetric modulated arc therapy. Conclusions: A nonisocentric implementation of station parameter optimized radiation therapy has been proposed for breast radiation therapy. The new treatment scheme overcomes the limitations of existing approaches and affords a useful tool for conformal breast radiation therapy, especially in cases with extreme chest wall curvature

  2. New concepts on risk factors of HPV and novel screening strategies for cervical cancer precursors.

    Syrjänen, K

    2008-01-01

    During the past several years, this author has been engaged in coordinating two major multicentre trials testing optional screening tools for cervical cancer (CC) in low-resource settings both in East Europe and in Latin America. These international trials include the NIS (New Independent States of the former Soviet Union) cohort (n = 3,187 women) and the LAMS (Latin American Screening) study (n = 12,114 women). In both studies, a sizeable cohort of women (887 and 1,011, respectively) have been prospectively followed-up to assess the natural history of high-risk human papillomavirus (HR-HPV) infections and the role of implicated risk factors as potential predictors of disease outcome (acquisition, persistence and clearance). In this communication some of the key observations recently reported from the NIS and LAMS studies will be discussed, with special emphasis on i) risk factors that are still controversial (i.e., oral contraception; OC, and smoking) or not previously studied (drug addiction), on ii) reproductive factors as potential cofactors of HPV infections in cervical carcinogenesis (i.e., age at menarche, menopause), and finally on iii) the performance of different screening strategies among young and older women. Although closely related to these topics, a detailed discussion on the dynamics of HPV infections (acquisition, persistence, clearance) and their predictive factors falls outside the scope of this communication, because they have been extensively discussed in a series of original reports and in a recent review of the author in this journal. The NIS cohort failed to establish OC as a risk factor of CC. In all future studies, the strong confounding effects from the lifestyle behavioural factors must be taken into account, while interpreting the data on OCs as potential risk factors of CC. Similarly, it now seems that the increased risk (if any) of CC among smokers seems to be attributed to the increased acquisition of HR-HPV infections, of which the

  7. Breaking the Ice: Strategies for Future European Research in the Polar Oceans - The AURORA BOREALIS Concept

    Lembke-Jene, L.; Biebow, N.; Wolff-Boenisch, B.; Thiede, J.; European Research Icebreaker Consortium

    2011-12-01

    Research vessels dedicated to work in polar ice-covered waters have only rarely been built. Their history began with Fritjof Nansen's FRAM, which he used for his famous first crossing of the Arctic Ocean 1893-1896. She served as example for the first generation of polar research vessels, at their time being modern instruments planned with foresight. Ice breaker technology has developed substantially since then. However, it took almost 80 years until this technical advance also reached polar research, when the Russian AKADEMIK FEDEROV, the German POLARSTERN, the Swedish ODEN and the USCG Cutter HEALY were built. All of these house modern laboratories, are ice-breakers capable to move into the deep-Arctic during the summer time and represent the second generation of dedicated polar research vessels. Still, the increasing demand in polar marine research capacities by societies that call for action to better understand climate change, especially in the high latitudes is not matched by adequate facilities and resources. Today, no icebreaker platform exists that is permanently available to the international science community for year-round expeditions into the central Arctic Ocean or heavily ice-infested waters of the polar Southern Ocean around Antarctica. The AURORA BOREALIS concept plans for a heavy research icebreaker, which will enable polar scientists around the world to launch international research expeditions into the central Arctic Ocean and the Antarctic continental shelf seas autonomously during all seasons of the year. The European Research Icebreaker Consortium - AURORA BOREALIS (ERICON-AB) was established in 2008 to plan the scientific, governance, financial, and legal frameworks needed for the construction and operation of this first multi-nationally owned and operated research icebreaker and polar scientific drilling platform. By collaborating together and sharing common infrastructures it is envisioned that European nations make a major contribution to

  8. The Effect of Using Concept Maps when Teaching the Transport System in Plants on Students’ Academic Achievement (The Case of Erzurum

    Murat KURT

    2011-12-01

    Full Text Available The aim of this study is searching how much the concept map biology teaching affects the students’ study when it is compared with the teacher-centered method. Two 11 grades students, whose success levels are equal, from an Anatolian High School in Erzurum are chosen as a study group. A class with teacher-centered method is determined as a control group and another class with concept map teaching method is determined as an experimental group. The test of the transport system of the plants is carried out as a pre- test and post-test(after a four-week teaching in order to compare the effects of the two teaching methods. This study went on for four weeks. The practices are performed by the researchers. The numeric data which are taken are evaluated in SPSS-15. In the statistics evaluation, a t-test is used for unconnected variable. The results are evaluated with 0.05 stage. As a result, it is obvious that teaching the transport system of the plants with the concept map method is more effective than teaching it with the traditional teaching method.

  9. A Modern Twist on the Beaumont and St. Martin Case: Encouraging Analysis and Discussion in the Bioethics Classroom with Reflective Writing and Concept Mapping

    Carlos C. Goller

    2014-09-01

    Full Text Available Historical ethical dilemmas are a valuable tool in bioethics courses. However, garnering student interest in reading and discussing the assigned cases in the classroom can be challenging. In an effort to actively engage undergraduate and graduate students in an Ethical Issues in Biotechnology course, an activity was developed to encourage reflection on a classical ethical dilemma between a patient, St. Martin, and his employer/caretaker, Beaumont. Two different texts were used to analyze the ethical ramifications of this relationship: a chapter in a popular press book and a short perspective in a medical journal. Participants read the book chapter for homework and discussed it in class. This easy read highlights the fundamental ethical issues in the relationship between two men. Students were then provided with a second text focusing on the scientific accomplishments achieved through Beaumont's experimentation on St. Martin. A structured worksheet prompted participants to reflect on their feelings after reading each text and create a concept map depicting the dilemma. Student-generated concept maps and written reflections indicate participants were able to list the ethical issues, analyze the situation, and evaluate the information provided. This activity not only encouraged higher-level thinking and reflection, it also mirrored the course's structured approach of using concept mapping and reflection to dissect ethical dilemmas.

  10. The quality of radiation care: The results of focus group interviews and concept mapping to explore the patient’s perspective

    Background and purpose: In this study, we explore the quality aspects of radiation care from the patient’s perspective in order to develop a draft Consumer Quality Index (CQI) Radiation Care instrument. Materials and methods: Four focus group discussions with (former) cancer patients were held to explore the aspects determining the quality of radiation care. The list of aspects generated was categorised based on similarity and importance in a concept mapping procedure. Results: Four focus group discussions revealed seven main themes related to the quality of radiation care: information provision, a patient-centred approach, professional competence, planning and waiting times, accessibility, cooperation and communication, and follow-up care. Results of concept mapping procedures revealed which items the patients considered to be most important. A radiation oncologist who is up to date about the patient’s file is of paramount importance for cancer patients receiving radiotherapy. Conclusions: The quality aspects found through focus group discussions provided useful insight into how patients experience radiation care. Furthermore, concept mapping made these results more solid. To evaluate the quality of radiation care from the patient’s perspective, these quality aspects will be guiding in the development of a CQI Radiation Care.

  12. GeoWall use in an Introductory Geology laboratory: Impacts in Student Understanding of Field Mapping Concepts

    Ross, L. E.; Kelly, M.; Springer, A. E.

    2003-12-01

    In the Fall semester of 2003, Northern Arizona University will introduce the GeoWall to its introductory geology courses. This presents an opportunity to assess the impact of this new technology on students' understanding of basic topographic concepts and the spatial relationships between geology, topography, and hydrology on a field trip. Introductory Geology fulfills the Lab Science component of the Liberal Studies Program at Northern Arizona University. The class is open to all Northern Arizona University students, and is most commonly taken by non-science majors. In this class students learn to: locate their position using maps, identify common minerals and rocks, recognize the relationship between geology and geomorphology, visualize how rocks exposed at the surface continue into the subsurface, and to draw conclusions about possible geologic hazards in different settings. In this study we will report how a GeoWall 3D visualization technology was used in a field study of a graben south of Flagstaff. The goal of the field exercise is to improve students' ability to synthesize data collected at field stops into a conceptual model of the graben, linking geology, geomorphology and hydrology. We plan to present a quantitative assessment of the GeoWall learning objectives from data collected from a paired test and control group of students. Teaching assistants (TAs) with two or more lab classes have been identified; these TAs will participate in both GeoWall and non-GeoWall lab exercises. The GeoWall use will occur outside of normal lab hours to avoid disrupting the lab schedule during the eighth week of lab. This field preparation exercise includes a 3D visualization of the Lake Mary graben rendered with the ROMA software. The following week, all students attend the graben field trip; immediately following the trip, students will interviewed about their gain in understanding of the geologic features illustrated during the field trip. The results of the post

  14. Gene and DNA concepts by UNIFAL-MG entering students and the effectiveness of drama as a Molecular Biology teaching strategy

    Marina Isidoro Silva

    2014-10-01

    Full Text Available The Molecular Biology concepts comprehension is important for understanding several Biological processes as well as to establish correlations and interrelations among cell processes and its interaction with the environment. The aim of this work was to evaluate the undergraduate students from the Universidade Federal de Alfenas-MG (UNIFAL-MG knowledge about gene and DNA concepts as well as to evaluate the effectiveness of drama as an innovative teaching strategy. This strategy was evaluated by the students` knowledge gain and scholar performance. The results showed the UNIFAL-MG beginners’ students presented defective concepts about gene and DNA composition and structure, probably due to deficient teaching-learning process before the University entrance. Drama was an efficient strategy to induce learning gain and to improve scholar performance of classes with a good initial level of knowledge.

  15. Evaluation of the User Strategy on 2d and 3d City Maps Based on Novel Scanpath Comparison Method and Graph Visualization

    Dolezalova, J.; Popelka, S.

    2016-06-01

    The paper is dealing with scanpath comparison of eye-tracking data recorded during case study focused on the evaluation of 2D and 3D city maps. The experiment contained screenshots from three map portals. Two types of maps were used - standard map and 3D visualization. Respondents' task was to find particular point symbol on the map as fast as possible. Scanpath comparison is one group of the eye-tracking data analyses methods used for revealing the strategy of the respondents. In cartographic studies, the most commonly used application for scanpath comparison is eyePatterns that output is hierarchical clustering and a tree graph representing the relationships between analysed sequences. During an analysis of the algorithm generating a tree graph, it was found that the outputs do not correspond to the reality. We proceeded to the creation of a new tool called ScanGraph. This tool uses visualization of cliques in simple graphs and is freely available at www.eyetracking.upol.cz/scangraph. Results of the study proved the functionality of the tool and its suitability for analyses of different strategies of map readers. Based on the results of the tool, similar scanpaths were selected, and groups of respondents with similar strategies were identified. With this knowledge, it is possible to analyse the relationship between belonging to the group with similar strategy and data gathered from the questionnaire (age, sex, cartographic knowledge, etc.) or type of stimuli (2D, 3D map).

  18. Map-Based Power-Split Strategy Design with Predictive Performance Optimization for Parallel Hybrid Electric Vehicles

    Jixiang Fan

    2015-09-01

    Full Text Available In this paper, a map-based optimal energy management strategy is proposed to improve the consumption economy of a plug-in parallel hybrid electric vehicle. In the design of the maps, which provide both the torque split between engine and motor and the gear shift, not only the current vehicle speed and power demand, but also the optimality based on the predicted trajectory of vehicle dynamics are considered. To seek the optimality, the equivalent consumption, which trades off the fuel and electricity usages, is chosen as the cost function. Moreover, in order to decrease the model errors in the process of optimization conducted in the discrete time domain, the variational integrator is employed to calculate the evolution of the vehicle dynamics. To evaluate the proposed energy management strategy, the simulation results performed on a professional GT-Suit simulator are demonstrated and the comparison to a real-time optimization method is also given to show the advantage of the proposed off-line optimization approach.

  19. Modeling and Mapping Golden-winged Warbler Abundance to Improve Regional Conservation Strategies

    Wayne E. Thogmartin

    2010-12-01

    Full Text Available Conservation planning requires identifying pertinent habitat factors and locating geographic locations where land management may improve habitat conditions for high priority species. I derived habitat models and mapped predicted abundance for the Golden-winged Warbler (Vermivora chrysoptera, a species of high conservation concern, using bird counts, environmental variables, and hierarchical models applied at multiple spatial scales. My aim was to understand habitat associations at multiple spatial scales and create a predictive abundance map for purposes of conservation planning for the Golden-winged Warbler. My models indicated a substantial influence of landscape conditions, including strong positive associations with total forest composition within the landscape. However, many of the associations I observed were counter to reported associations at finer spatial extents; for instance, I found Golden-winged Warblers negatively associated with several measures of edge habitat. No single spatial scale dominated, indicating that this species is responding to factors at multiple spatial scales. I found Golden-winged Warbler abundance was negatively related with Blue-winged Warbler (Vermivora cyanoptera abundance. I also observed a north-south spatial trend suggestive of a regional climate effect that was not previously noted for this species. The map of predicted abundance indicated a large area of concentrated abundance in west-central Wisconsin, with smaller areas of high abundance along the northern periphery of the Prairie Hardwood Transition. This map of predicted abundance compared favorably with independent evaluation data sets and can thus be used to inform regional planning efforts devoted to conserving this species.

  1. Modeling eye movements in visual agnosia with a saliency map approach: bottom-up guidance or top-down strategy?

    Foulsham, Tom; Barton, Jason J S; Kingstone, Alan; Dewhurst, Richard; Underwood, Geoffrey

    2011-08-01

    Two recent papers (Foulsham, Barton, Kingstone, Dewhurst, & Underwood, 2009; Mannan, Kennard, & Husain, 2009) report that neuropsychological patients with a profound object recognition problem (visual agnosic subjects) show differences from healthy observers in the way their eye movements are controlled when looking at images. The interpretation of these papers is that eye movements can be modeled as the selection of points on a saliency map, and that agnosic subjects show an increased reliance on visual saliency, i.e., brightness and contrast in low-level stimulus features. Here we review this approach and present new data from our own experiments with an agnosic patient that quantifies the relationship between saliency and fixation location. In addition, we consider whether the perceptual difficulties of individual patients might be modeled by selectively weighting the different features involved in a saliency map. Our data indicate that saliency is not always a good predictor of fixation in agnosia: even for our agnosic subject, as for normal observers, the saliency-fixation relationship varied as a function of the task. This means that top-down processes still have a significant effect on the earliest stages of scanning in the setting of visual agnosia, indicating severe limitations for the saliency map model. Top-down, active strategies-which are the hallmark of our human visual system-play a vital role in eye movement control, whether we know what we are looking at or not. PMID:21316191

  2. Atrial Tachycardias Occurring After Atrial Fibrillation Ablation: Strategies for Mapping and Ablation

    Stavros Mountantonakis, MD

    2010-10-01

    Full Text Available The occurrence of left atrial tachycardias (AT after catheter ablation for atrial fibrillation (AF is common, especially after more extensive ablation of persistent AF. These AT are invariably symptomatic and often do not respond to medical therapy. The initial strategy involves ventricular rate control, cardioversion, and observation as some tachycardias may resolve with time. For persistent ATs, effective management frequently requires catheter intervention. Careful characterization of the tachycardia mechanism is essential in designing an effective ablation strategy that would also avoid further creation of pro-arrhythmic substrate. With this review, we summarize the incidence, mechanism, diagnosis and treatment of ATs occurring after AF ablation.

  7. An alternative validation strategy for the Planck cluster catalog and $y$-distortion maps

    Khatri, Rishi

    2015-01-01

    We present an all sky map of the $y$-type distortion calculated from the full mission Planck HFI (High Frequency Instrument) data using the recently proposed approach to component separation based on parametric model fitting and model selection. This simple model selection approach allows us to distinguish between carbon monoxide (CO) line emission and $y$-type distortion, something that is not possible using the internal linear combination based methods. We create a mask to cover the regions of significant CO emission relying on the information in the $\\chi^2$ map obtained when fitting for the $y$-distortion and CO emission to the lowest four HFI channels. We revisit the second Planck cluster catalog and try to quantify the quality of the cluster candidates in an approach that is similar in spirit to Aghanim et al. (2014). We find that at least $93\\%$ of the clusters in the cosmology sample are free of CO contamination. We also find that $59\\%$ of unconfirmed candidates may have significant contamination fro...

  8. The effects of concept and vee mappings under three learning modes on Jamaican eighth graders' knowledge of nutrition and plant reproduction

    Ugwu, Okechukwu; Soyibo, Kola

    2004-01-01

    The first objective of this study was to investigate if the experimental students' post-test knowledge of nutrition and plant reproduction would be improved more significantly than that of their control group counterparts based on their treatment, attitudes to science, self-esteem, gender and socio-economic background. Treatment involved teaching the experimental students under three learning modes--pure cooperative, cooperative-competitive and individualistic whole class interpersonal competitive condition--using concept and vee mappings and the lecture method. The control groups received the same treatment but were not exposed to concept and vee mappings. This study's second objective was to determine which of the three learning modes would produce the highest post-test mean gain in the subjects' knowledge of the two biology concepts. The study's sample comprised 932 eighth graders (12-13-year-olds) in 14 co-educational comprehensive high schools randomly selected from two Jamaican parishes. An integrated science performance test, an attitudes to science questionnaire and a self-esteem questionnaire were used to collect data. The results indicated that the experimental students (a) under the three learning modes, (b) with high, moderate, and low attitudes to science, and (c) with high, moderate, and low self-esteem, performed significantly better than their control group counterparts. The individualist whole class learning mode engendered the highest mean gain on the experimental students' knowledge, while the cooperative-competitive learning mode generated the highest mean gain for the control group students.

    Schmitz, Nicole; Jaumann, Ralf; Coates, Andrew; Griffiths, Andrew; Hauber, Ernst; Trauthan, Frank; Paar, Gerhard; Barnes, Dave; Bauer, Arnold; Cousins, Claire

    2010-05-01

    Geologic context as a combination of orbital imaging and surface vision, including range, resolution, stereo, and multispectral imaging, is commonly regarded as basic requirement for remote robotic geology and forms the first tier of any multi-instrument strategy for investigating and eventually understanding the geology of a region from a robotic platform. Missions with objectives beyond a pure geologic survey, e.g. exobiology objectives, require goal-oriented operational procedures, where the iterative process of scientific observation, hypothesis, testing, and synthesis, performed via a sol-by-sol data exchange with a remote robot, is supported by a powerful vision system. Beyond allowing a thorough geological mapping of the surface (soil, rocks and outcrops) in 3D, using wide angle stereo imagery, such a system needs to be able to provide detailed visual information on targets of interest in high resolution, thereby enabling the selection of science targets and samples for further analysis with a specialized in-situ instrument suite. Surface vision for ESA's upcoming ExoMars rover will come from a dedicated Panoramic Camera System (PanCam). As integral part of the Pasteur payload package, the PanCam is designed to support the search for evidence of biological processes by obtaining wide angle multispectral stereoscopic panoramic images and high resolution RGB images from the mast of the rover [1]. The camera system will consist of two identical wide-angle cameras (WACs), which are arranged on a common pan-tilt mechanism, with a fixed stereo base length of 50 cm. The WACs are being complemented by a High Resolution Camera (HRC), mounted between the WACs, which allows a magnification of selected targets by a factor of ~8 with respect to the wide-angle optics. The high-resolution images together with the multispectral and stereo capabilities of the camera will be of unprecedented quality for the identification of water-related surface features (such as sedimentary

There are many types of SOM algorithms to solve the TSP found in the literature, whereas the purpose of this paper is to look for the incorporation of an efficient initialization methods and the definition of a parameters adaptation law to achieve better results and a faster convergence. Aspects of parameters adaptation, selecting the number of nodes of neurons, index of winner neurons and effect of the initial ordering of the cities, as well as the initial synaptic weights of the modified SOM algorithm are discussed. The complexity of the modified SOM algorithm is analyzed. The simulated results show an average deviation of 2.32% from the optimal tour length for a set of 12 TSP instances

    Complex applications implemented as Systems on Chip (SoCs) demand extensive use of system level modeling and validation. Their implementation gathers a large number of complex IP cores and advanced interconnection schemes, such as hierarchical bus architectures or networks on chip (NoCs). Modeling applications involves capturing its computation and communication characteristics. Previously proposed communication weighted models (CWM) consider only the application communication aspects. This work proposes a communication dependence and computation model (CDCM) that can simultaneously consider both aspects of an application. It presents a solution to the problem of mapping applications on regular NoCs while considering execution time and energy consumption. The use of CDCM is shown to provide estimated average reductions of 40% in execution time, and 20% in energy consumption, for current technologies.

    Looming energy crisis, climate change concerns coupled with decreasing fossil fuel resources has garnered significant global attention toward development of alternative, renewable, carbon-neutral and eco-friendly fuels to fulfil burgeoning energy demands. Waste utilization and its management are being pursued with renewed interest due to the gamut of biobased products it can offer apart from providing enough energy to meet a major fraction of the world's energy demand. Biorefining is the sustainable processing of biomass into a spectrum of marketable products and energy. Integrating all components of waste treatment culminating into biobased products and energy recovery in a single integrated waste biorefinery is self sufficient, highly sustainable and is very beneficial. Designing systematic innovation policies are essential for development and commercialization of new technologies in this important futuristic research area. This communication explores Innovation Policy Road Mapping (IPRM) methodology available in the literature and applies it to design integrated waste biorefinery. PMID:27039350

  15. Generation IV nuclear energy systems: road map and concepts. 1. A Long-Term Energy Source Based on an HTGR Concept

    Today, the major component of the world's power consumption is based on natural gas and petroleum products. The major challenge for research and development of new energy sources is to find environmentally and economically acceptable ways to make a transition away from these increasingly scarce primary fuels. Technologies based on nuclear fission offer a promising solution. Reactor designs that capitalize on inherent safety characteristics are attractive choices for the further development of nuclear power. Such a system is the high temperature gas-cooled reactor (HTGR). Current research on the HTGR concept concentrates on a reactor with a pebble bed core. Analysis focuses on several areas. These include the following conceptual studies: 1. potential combinations of advanced fuel compositions and structural materials that improve performance characteristics of the pebble bed HTGR; 2. an advanced pebble bed HTGR design with a helium temperature elevated to >1300 K that provides the possibility of obtaining higher efficiency of the thermodynamic cycle; 3. prolonged operation of the pebble bed HTGR on a single fuel loading reaching high burnups. The results obtained from the listed foregoing studies are presented and discussed in this paper. As in all conventional reactors, during operation of the pebble bed, HTGR fissile material is being burned. This loss of fissile material in the fuel needs to be compensated for. Compensation of the fuel depletion can be performed by external actions, such as replacement or addition of new fuel, control rod motion, or internal conversion of fertile material into fissile material in the pebble bed HTGR core. The possibility of sustaining criticality during a long-term operation based on the mechanism of internal conversion has been demonstrated. The main idea of the present analysis consists of minimizing the external action required for the pebble bed HTGR toward prolonged operation on a single fuel loading. Flexibility of the

    Next-generation sequencing opens the way for genomic studies of diversity even for non-model crops and animals. Genome reduction techniques are becoming progressively more popular as they allow a fraction of the genome to be sequenced for multiple individuals and/or populations. These techniques are an efficient way to explore genome diversity in non-model crops and animals for which no reference genome is available. Genome reduction techniques emerged with the development of specific pipelines such as UNEAK (Universal Network Enabled Analysis Kit) and Stacks. However, even for non-model crops and animals, transcriptomes are easier to obtain, thereby making it possible to directly map reads. We investigate the direct use of transcriptome as an alternative strategy. Our specific objective was to compare SNPs obtained from the UNEAK pipeline as well as SNPs obtained by directly mapping genotyping-by-sequencing reads on a transcriptome. We assessed the feasibility of both SNP datasets, UNEAK and transcriptome mapping, to investigate the diversity of 91 samples of wild pearl millet sampled across its distribution area. Both approaches produced several tens of thousands of single nucleotide variants, but differed in the way the variants were identified, leading to differences in the frequency spectrum associated with marked differences in the assessment of diversity. Difference in the frequency spectrum significantly biased a large set of diversity analyses as well as detection of selection approaches. However, whatever the approach, we found very similar inference of genetic structure, with three major genetic groups from West, Central, and East Africa. For non-model crops, using transcriptome data as a reference is thus a particularly promising way to obtain a more thorough analysis of datasets generated using genome reduction techniques.

  18. Spatial Vulnerability Map and Distributed Response Strategies for Irrigation System Under Climate Change

    It is an important issue whether irrigation systems can continuously provide quality service under climate change conditions. The streamflow irrigation system, which delivers water from a river directly, is still widely applied in Taiwan. Due to the impacts of climate change, the amount of available streamflow may decrease during dry season and higher variation of flows can be expected, which influences irrigation systems severely. Furthermore, sub-irrigation areas may have different levels of impacts under climate change. Instead of applying the adaptation strategies to the whole irrigation areas, different adaptive measures should be considered according to the vulnerability of each sub-irrigation area in order to face the impacts of climate change. The purposes of this study include defining the carrying capacity of an irrigation system, developing spatial distributed assessment methods through geographic information system and discussing how to develop adaptation systems for the areas which are more vulnerable. In this study, both agricultural and domestic water supply systems of the Touchien creek watershed are considered in this study. Future water demands of agriculture are estimated under the change of temperature and rainfall, and the amount of water supply to each sub-irrigation area is calculated according to its area and water losses. As for public water uses, the most restrict scenarios are taken in, e.g. the largest impact toward agriculture in the Touchien creek watershed. Then, the vulnerability of sub-irrigation areas is quantified by agricultural shortage index (ASI). ASI represents the percentage of crop yields in that area comparing with its potential crop yields. At last, the spatial distribution of vulnerability is established in order to emphasize the climate change impacts on each sub-irrigation area and to analyze their possible responses. Possible distributed adaptive strategies are proposed in this study too. Keywords: Vulnerability

    Recently, manifold dynamics has assumed an increasing relevance for analysis and design of low-energy missions, both in the Earth-Moon system and in alternative multibody environments. With regard to lunar missions, exterior and interior transfers, based on the transit through the regions where the collinear libration points L1 and L2 are located, have been studied for a long time and some space missions have already taken advantage of the results of these studies. This paper is focused on the definition and use of a special isomorphic mapping for low-energy mission analysis. A convenient set of cylindrical coordinates is employed to describe the spacecraft dynamics (i.e. position and velocity), in the context of the circular restricted three-body problem, used to model the spacecraft motion in the Earth-Moon system. This isomorphic mapping of trajectories allows the identification and intuitive representation of periodic orbits and of the related invariant manifolds, which correspond to tubes that emanate from the curve associated with the periodic orbit. Heteroclinic connections, i.e. the trajectories that belong to both the stable and the unstable manifolds of two distinct periodic orbits, can be easily detected by means of this representation. This paper illustrates the use of isomorphic mapping for finding (a) periodic orbits, (b) heteroclinic connections between trajectories emanating from two Lyapunov orbits, the first at L1, and the second at L2, and (c) heteroclinic connections between trajectories emanating from the Lyapunov orbit at L1 and from a particular unstable lunar orbit. Heteroclinic trajectories are asymptotic trajectories that travels at zero-propellant cost. In practical situations, a modest delta-v budget is required to perform transfers along the manifolds. This circumstance implies the possibility of performing complex missions, by combining different types of trajectory arcs belonging to the manifolds. This work studies also the possible
