    Full Text Available This abstract reports  the  use of concept  maps applied  to the evaluation of concepts  learned  through the use of an educational software to study  metabolic  pathways called Diagrama Metabolico Dinamico Virtual  do Ciclo de Krebs (DMDV.  Experience  with the use of this method  was carried  through  with two distinct groups  of students.  The  first  group  was composed  by 24 students (in  2003 who used DMDV during  the  classes (computer room.  The second group was formed by 36 students (in 2004 who could access DMDV software anytime  through  the intranet. The construction of the conceptual map by the student permits  the representation of knowledge, the mental  processes that were absorved and the adaptation during the study,  building new mental schemes that could be related to the concept of reflexioning  abstraction (Piaget, 1995 during  the  process of operation  with  these  concepts.   The evaluation of knowlegde was made by the analysis  of three conceptual  maps constructed by each one of them:   (a  one map  before initiating the  study  with  DMDV,  (b  the  second just  after  the  study and (c the third  one two months  later.  We used the following criteria  for the analysis:  predominance of associative  over classificatory  character; correct concepts  and  relationships; coherence;  number  of relationships;  creativity and  logic.   The  initial  maps  showed  that all  students had  some  previous mental scheme  about  the proposed  concept.    All final  concept maps  showed  an  expansion  of the concepts  as compared  to the initial  maps, something  which can be seen even by a mere glance at the size of graphics.  A purely visual comparison  between the maps indicated  that new elements have been added.   The  associative  character has been shown to predominate as compared  to the  classificatory one.  The  results  obtained  suggest the  validity  of using concept  maps  as a strategy to  monitor  the cognitive process, both  by the teacher  and by the student him/herself.

  4. 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. A case study of meaningful learning in a collaborative concept mapping strategy as a preparation for a college biology laboratory

    Carter, Catherine Wilburn Evelyn

    Statement of the problem. The purpose of this research was to add to our understanding of meaningful learning by examining the process of collaborative concept mapping and student interaction during knowledge construction. Laboratory learning has been hampered by inadequacies of students' conceptual understanding and laboratory preparation. Believing that people construct their own knowledge and that collaboration might assist in these constructions, this research examined student dialog and written products related to their college general biology laboratory experiences. The following questions guided the research: (a) What negotiations and other interactions take place between students who jointly construct propositions and concept maps? (b) What thinking and understanding takes place as students are constructing biology concepts? (c) What awareness do students have about their construction of biological concepts and about the use of these concept mapping strategies? Method. This study utilized qualitative and interpretive methodologies and a case study approach with purposeful sampling. Students in college general biology laboratory used an instructional strategy in which they independently constructed propositions from laboratory concepts. While being audio taped, pairs of students negotiated these propositions and used them to form concept maps. The data sets resulting from these methods, solicited personal documents including written proposition lists, concept maps, and examinations, were examined along with tape recorded conversations. Results. Analysis of interaction data revealed that most students paid only moderate attention to each other's comments. Most commonly observed cooperative behaviors were seeking meaning, providing explanations, and completion of partner's statements. The degree of pair symmetry did not consistently influence student interactions or cooperative behaviors. Students used easily memorized, but not necessarily accurate, answers. They had difficulty in focusing on abstract concepts and in forming explicit relationships. They also had difficulty with the hierarchial nature of concept maps. Students seeking improved study habits perceived that there was value to these activities. Conclusions. Emphasis on proposition formation prior to concept map construction was shown to effectively aid knowledge construction especially in relatively balanced student pairs. The theoretical framework of constructivism, concept mapping, and collaboration jointly provided a synergistic referent for understanding the complexity of meaningful learning.

    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.

    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, teachers, artists, and web designers, a smaller scale collaborative effort can result in an effective mini-exhibit. Online concept maps can present a large quantity of information in bite-size chunks, demonstrating interrelationships between pieces of information without inundating visitors. SpicyNodes uses radial mapping technology to enable visitors to learn about a topic or search for information in intuitive and organic ways. This online concept mapping tool can be used as a portal to invite exploration into topics, or as a means of displaying hierarchies of information. With nodes that contain text, audio, video, and links, interactive online concept maps especially engage visual, kinesthetic, and nonlinear learners. SpicyNodes is also useful for scientists who wish to complement papers, chapters, and books with an online interface that is especially appealing to nonlinear learners. Essentially, SpicyNodes shifts the burden of discovery from the reader to the author. For example, the author may create a nodemap on climate change with hundreds of nodes, but as visitors drill through the nodemap for information (e.g. from climate change to atmospheric gases to carbon dioxide), they see only a few nodes at a time and are not overwhelmed.

    In urban transformation some of the most interesting and complex design challenges are related to redevelopment of city centres and waterfronts. Here the conflicts between ‘the old’ and ‘the new’ are the largest, and here the potentials for mistakes are at a critical level. One of the problems is, that new developments often employ very modest research on the subject and often very little has been done in order to challenge traditional concepts and to invent new sustainable concepts for redevelopment. In order to avoid mistakes in urban redevelopment we need to learn from research and evaluation of the best planning practice. But what might be just as important is to learn from concept development practice, which can give us a comprehensive understanding of our complex cities and make us develop a way of experiencing the unique qualities of the architectural typologies at the site. Finally the combination of research and design based development can provide us with a range of conceptual models for alternative development of different valuable parts of the city. This article is focusing on the design-based methods in concept development, which can be tested with the purpose of developing new design concepts and to generate easily grasped images of a coherent transformation. The case is taken form the water front development in Aalborg, where a series of architecture and building workshops has been conducted. The methodology is described in relation to three workshops from 2005 and 2008. The concepts and strategies are briefly described in the article, and the adaption by city planners and developers has been critical reviewed.

    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.

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

    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.

The authorsdescribe principles, functions, advantages and limitations of this method and discuss its use in different areas. Use of concept mapping in educational situations is demonstratedon concept maps made by students of Charles University in Prague, Faculty of Education during a course on „Authority in Education“. At the beginning of the course, studentslearned about the concept mapping method and created their first concept map with key concept „teacher authority“. During the course, they studied authority in educationand discussed about their first concept maps with the teacher and other students. At the end of the course, the students tried to improve their maps. The concept map helpedthe students to represent the complexity of the studied issue very clearly. The students said that they were going to use concept mapping in their further study and classworkwith children. The authors show the problematic aspects of creating the maps and also examples of (inappropriately chosen concepts and (cross-links between them.

    2006-01-01

    Full Text Available Graphic organizers such as webs, time lines, Venn diagrams, flowcharts, and concept maps are well known and widely used instructional and learning tools. They help teachers and students not only to identify and visually represent their views and knowledge but also to recognize and depict relationships among concepts. This article discusses the use of concept maps in early childhood education. In light of a theory that suggests that information is processed and stored in memory in both linguistic and visual forms, it is argued that concept maps can be used in early childhood classrooms to help children organize and spatially represent both what they know and what they are thinking. Once children learn how to “read” and make concept maps, teachers can also use them to identify children’s preexisting knowledge or misconceptions as well as use them as an evaluation tool. The article also considers the role of concept maps in teacher planning. Concept maps can help teachers to plan, structure, and sequence the content of their teaching. Finally, the article illustrates some of the issues involved in using concept maps with preschool children and suggests ways of introducing children to the process of constructing their own concept maps.

    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

    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.

    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

    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. However, the students who collaboratively generated concept maps created significantly higher quality concept maps than those who individually generated concept maps. The researcher concluded that the concept mapping software, Inspiration(TM), fostered construction of students' concept maps individually or collaboratively for science learning and helped students capture their evolving creative ideas and organize them for meaningful learning. Students in both the individual and the collaborative concept mapping groups had positive attitudes toward concept mapping using Inspiration(TM) software.

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

    Science.gov (United States)

    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-test shows that concept mapping added to the participants' conceptual understanding whether the participants learned the concepts through readings or stations. Finally, field assignments allowed the participants to apply knowledge that they learned in their science methods course in their classroom placements. This study has implications for teacher preparation programs, staff development, and conceptual change practices in field placements.

    2007-12-01

    Full Text Available This paper reports on a quasi-experimental study which examined the effectiveness of concept mapping as a revision tool in enhancing pupils' examination performances in primary science. The research objective seeks to determine whether there are significant differences in achievement between the concept mapping and traditional method of revision groups after treatment in both primary gifted and mainstream classes. This research hopes to establish the relationship between pupils' understanding of science concepts along with performance and use of concept mapping as a revision tool in primary science. Findings of this study will be useful towards the implementation of concept mapping as an instructional and revision tool in the primary science classroom.Objective:The purpose of this study is to examine, in a systematic manner, the effectiveness of concept mapping as a revision tool in enhancing pupils' learning and understanding of primary science concepts.Interest in knowledge representation and knowledge elicitation has increased greatly over the past decade and new literatures are emerging on this topic. However, a literature search on concept mapping in Singapore classrooms revealed that thus far no systematic studies have been done, especially in the area of primary science education. Research on concept mapping has only been systematically examined and documented in the teaching of lower secondary history (Loh, 1987 and secondary science (Mohamed Nasir, 1992 in the local context. There were three conference/seminar papers involving the use of concept mapping in science in Singapore (Chang, 1989; Lloyd, 1992; Wan, Lee, Goh & Chia, 1992This study extends the research on concept mapping done in Singapore to primary science classrooms in terms of its effectiveness and potential in enhancing learning and understanding science concepts as compared to the traditional method of revision using outlining method among both the gifted and main stream pupils.Significance:Findings from this study will go some way in addressing the lack of knowledge arising from systematic studies on the use of concept mapping in primary science classrooms in Singapore.It will also complement existing knowledge concerning the use of concept mapping in science classrooms overseas, as well as locally in the use of concept mapping in secondary and non-science classrooms.Research questions:The following research questions are proposed to further investigate this learning heuristic. RQ1. Does concept mapping as a revision tool help primary school pupils (both gifted and main stream achieve better performance in terms of marks in science tests and assessments?RQ2. Does concept mapping as a revision tool enhance concept retention in pupils?

    2012-01-01

    For human factors (HF) to avoid being considered of "side-car" status, it needs to be positioned within the organization in such a way that it affects business strategies and their implementation. Tools are needed to support this effort. This paper explores the feasibility of applying a technique from operational research called cognitive mapping to link HF to corporate strategy. Using a single case study, a cognitive map is drawn to reveal the complex relationships between human factors and achieving an organization's strategic goals. Analysis of the map for central concepts and reinforcing loops enhances understanding that can lead to discrete initiatives to facilitate integration of HF. It is recommended that this technique be used with senior managers to understand the organizations` strategic goals and enhance understanding of the potential for HF to contribute to the strategic goals.

    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.

  20. What's in a Word? Concept mapping: a graphical tool to reinforce learning of epidemiological concepts.

    Science.gov (United States)

    Berglund, Anita

    2015-12-01

    Epidemiology is founded on central concepts and principles, essential for conducting, reporting and critically assessing epidemiological studies. Definitions of the many concepts used in the field can be found in textbooks and via the Dictionary of Epidemiology. However, central epidemiological concepts are labelled and used in multiple ways, leading to potential misunderstanding when communicating in different fora. The aim here is to describe collaborative concept mapping, and illustrate how it can be used in teaching and learning epidemiology. Concept mapping is a cognitive technique that is widely used in the education of medical and allied health professions as a tool for critical thinking, and to assimilate new knowledge, but it is still under-utilised in epidemiology. A specific concept map is defined by the aim and question in focus; it is thus framed by a context. The concept map is constructed using a set of concepts (nodes) that are linked with arrows or lines (links). Words and phrases (connective terms) are used to explain relationships between the concepts linked. Different domains can be interconnected by linking concepts in different areas (cross-links). The underlying structure of knowledge is often complex, and consequently concept maps can be constructed using different topological features. Here we provide an illustrative example of concept mapping, based on a set of 'basic' concepts introduced in a doctoral course in epidemiology. In summary, concept mapping is a compelling, active learning tool, which can promote shared deeper knowledge of concepts and their complex interconnections, thereby facilitating a better understanding of epidemiological research.

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.

  11. Construction of concept maps as tool for Biochemistry learning

    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. The students worked in small groups and, at each module, there were (1 an oriented study, guided by questions, texts and schemes, supervised by the teachers, (2 the construction of individual concept maps, where the local and systemic effects of the venoms should be predicted by their biochemical composition and (3 the construction of a new map by the group, incorporating the information of the individual maps. The difficulty level of these tasks was gradually increased throughout the course, with lesser time to carry out the tasks, lesser assistance during the oriented study and even lesser information on the venom effects.The course assessment was given by the number, quality and correction of the concepts relationship present in the concept maps, through a questionnaire and by the teachers’ observation. The concept maps produced exceeded the expectation, being gradually more complex at each module. The answers to the questionnaire, in a 1 to 5 scale, showed that the course answered the students’ expectations (4,3, that the topics chosen were satisfactory (4,4 and that the students recommend the course to colleagues (4,6. Besides, the majority agreed that the concept maps improved the learning of the course content (4,5 and that this methodology should be adopted in other courses and disciplines.

    Moreno, Megan A; Kota, Rajitha; Schoohs, Shari; Whitehill, Jennifer M

    2013-07-01

    Facebook is a popular social media Web site that has been hypothesized to exert potential influence over users' attitudes, intentions, or behaviors. The purpose of this study was to develop a conceptual framework to explain influential aspects of Facebook. This mixed methods study applied concept mapping methodology, a validated five-step method to visually represent complex topics. The five steps comprise preparation, brainstorming, sort and rank, analysis, and interpretation. College student participants were identified using purposeful sampling. The 80 participants had a mean age of 20.5 years, and included 36% males. A total of 169 statements were generated during brainstorming, and sorted into between 6 and 22 groups. The final concept map included 13 clusters. Interpretation data led to grouping of clusters into four final domains, including connection, comparison, identification, and Facebook as an experience. The Facebook Influence Concept Map illustrates key constructs that contribute to influence, incorporating perspectives of older adolescent Facebook users. While Facebook provides a novel lens through which to consider behavioral influence, it can best be considered in the context of existing behavioral theory. The concept map may be used toward development of potential future intervention efforts. PMID:23621717

  2. Attaining meaningful learning of concepts in genetics and ecology: An examination of the potency of the concept-mapping technique

    Science.gov (United States)

    Okebukola, Peter Akinsola

    Studies have shown that in their study of biology, students perceive genetics and ecology to be difficult areas to learn. This has translated into rote learning of genetics and ecological concepts and reflected in poor performance in tests involving these concepts. Considering the importance of genetics and ecology to man's understanding of himself and his environment, there is a need to inquire into ways of ensuring that students attain meaningful learning of genetics and ecology rather than learning by rote. The efficacy of the concept-mapping strategy was tried out in this study with 138 predegree biology students. The results showed that the 63 students in the experimental group who employed the concept-mapping technique performed significantly better on the test of meaningful learning in genetics, t(136) = 16.01. p < 0.001, and ecology, t(136) = 12.27, p < 0.001, than their control group counterparts (N = 75). The implications of these results for teacher education in biology are addressed in the article.

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

    Directory of Open Access Journals (Sweden)

    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. Åhlberg?s and his research group?s 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 students? 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 group?s research, concept mapping has been tested in all main phases of research, teaching and learning.

  9. Scanning and Mapping Strategies for CMB Experiments

    CERN Document Server

    Wright, E L

    1996-01-01

    CMB anisotropy experiments seeking to make maps with more pixels than the 6144 pixels used by the COBE DMR need to address the practical issues of the computer time and storage required to make maps. A simple, repetitive scan pattern reduces these requirements but leaves the experiment vulnerable to systematic errors and striping in the maps. In this paper I give a time-ordered method for map-making with one-horned experiments that has reasonable memory and CPU needs but can handle complex COBE-like scans paths and 1/f noise.

    Saglam, Yilmaz

    The objective of this study was to investigate the experiences of middle school students when concept maps were used as a learning tool. Twenty-nine students' written responses, concept maps and videotapes were analyzed. Out of 29 students, thirteen students were interviewed using a semi-structured and open-ended interview protocol. The students' initial written responses provided us with the students' initial reactions to concept maps. The videotapes captured the students' behavior, and interpersonal interactions. The interviews probed students': (1) knowledge about drawing concept maps, (2) perception of the meaning and usefulness of concept maps, and (3) attitudes towards concept maps. The results indicated that the students viewed concept maps as useful tools in learning science. They believed that concept maps organized and summarized the information, which thereby helped them understand the topic easily. They also believed that concept maps had some cognitive benefits. However, the students viewed concept maps as hard to construct because it was difficult for the students to think of related concepts. The students' initial written responses, interviews and videotapes indicated that the students seemed to see both positive and negative aspects of concept maps. Some students' had more positive and some had more negative attitudes.

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

    Science.gov (United States)

    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-specific form of concept map, called Knowledge Integration Map (KIM), which aims to help learners connect ideas across levels (for example, genotype and phenotype levels) towards an integrated understanding of evolution. Using a design-based research approach (Brown, 1992; Cobb et al., 2003), three iterative studies were implemented in ethically and economically diverse public high schools classrooms using the web-based inquiry science environment (WISE) (Linn et al., 2003; Linn et al., 2004). Study 1 investigates concept maps as generative assessment tools. Study 1A compares the concept map generation and critique process of biology novices and experts. Findings suggest that concept maps are sensitive to different levels of knowledge integration but require scaffolding and revision. Study 1B investigates the implementation of concept maps as summative assessment tools in a WISE evolution module. Results indicate that concept maps can reveal connections between students' alternative ideas of evolution. Study 2 introduces KIMs as embedded collaborative learning tools. After generating KIMs, student dyads revise KIMs through two different critique activities (comparison against an expert or peer generated KIM). Findings indicate that different critique activities can promote the use of different criteria for critique. Results suggest that the combination of generating and critiquing KIMs can support integrating evolution ideas but can be time-consuming. As time in biology classrooms is limited, study 3 distinguishes the learning effects from either generating or critiquing KIMs as more time efficient embedded learning tools. Findings suggest that critiquing KIMs can be more time efficient than generating KIMs. Using KIMs that include common alternative ideas for critique activities can create genuine opportunities for students to critically reflect on new and existing ideas. Critiquing KIMs can encourage knowledge integration by fostering self-monitoring of students' learning progress, identifying knowledge gaps, and

  17. The Spanish indoor radon mapping strategy

    International Nuclear Information System (INIS)

    Indoor radon mapping still represents a valuable tool for drawing the picture of the exposure of general public due to radon and radon progeny inhalation in a residential context. The information provided by means of a map is useful not only as awareness and strategic element for authorities and policy-makers, but also as a scientific start-up point in the design of epidemiological and other specific studies on exposure to natural radiation. The requirements for a good mapping are related to harmonisation criteria coming from European recommendations, as well as to national/local characteristics and necessities. Around 12 000 indoor radon measurements have been made since the Spanish national radon programme began at the end of the 1980's. A significant proportion of them resulted from the last campaign performed from 2009 to 12. This campaign completed the first version of a map based on a grid 10 x 10 km2. In this paper, the authors present the main results of a new map together with the criteria adopted to improve the number of measurements and the statistical significance of them. (authors)

    Full Text Available Introduction: Concept mapping is an innovative tool that would help hospital educators and nurses to promote their knowledge and clinical decision making skills. The aim of this study was to investigate the effect of concept mapping on clinical decision making skills of nurses working in the intensive care unit (ICU. Methods: The quasi-experimental, non-equivalent control group, pretest-posttest design was conducted among baccalaureate nurses working in an intensive care unit. Forty two nurses were recruited and data gathering was performed through a self-administered questionnaire. Statistical analysis was conducted by SPSS software package version 16.0. 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.

    2012-08-01

    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.

    2013-03-01

    Full Text Available The foundations of the Meaningful Learning Theory (MLT were laid by David Ausubel. The MLT was highly valued by the contributions of Joseph Novak and D. B. Gowin. Unlike other learning theories, the MLT has an operational component, since there are some instruments based on it and with the meaningful learning facilitation as aim. These tools were designated graphic organizers by John Trowbridge and James Wandersee (2000, pp. 100-129. One of them is the concept map created by Novak to extract meanings from an amalgam of information, having currently many applications. The other one is the Vee diagram or knowledge Vee, also called epistemological Vee or heuristic Vee. It was created by Gowin, and is an excellent organizer, for example to unpack and make transparent the unclear information from an information source. Both instruments help us in processing and becoming conceptually transparent the information, to facilitate the cognitive process of new meanings construction. In this work, after a brief introduction, it will be developed the epistemological and psychological grounds of MLT, followed by a reference to constructivist learning environments facilitators of the meaningful learning, the characterization of concept maps and exemplification of its use in various applications that have proved to be very effective from the standpoint of meaningful learning.

  2. Requirements and design concept for a facility mapping system

    International Nuclear Information System (INIS)

    The Department of Energy (DOE) has for some time been considering the Decontamination and Dismantlement (D ampersand D) of facilities which are no longer in use, but which are highly contaminated with radioactive wastes. One of the holdups in performing the D ampersand D task is the accumulation of accurate facility characterizations that can enable a safe and orderly cleanup process. According to the Technical Strategic Plan for the Decontamination and Decommissioning Integrated Demonstration, open-quotes the cost of characterization using current baseline technologies for approximately 100 acres of gaseous diffusion plant at Oak Ridge alone is, for the most part incalculableclose quotes. Automated, robotic techniques will be necessary for initial characterization and continued surveillance of these types of sites. Robotic systems are being designed and constructed to accomplish these tasks. This paper describes requirements and design concepts for a system to accurately map a facility contaminated with hazardous wastes. Some of the technologies involved in the Facility Mapping System are: remote characterization with teleoperated, sensor-based systems, fusion of data sets from multiple characterization systems, and object recognition from 3D data models. This Facility Mapping System is being assembled by Oak Ridge National Laboratory for the DOE Office of Technology Development Robotics Technology Development Program

    2013-01-01

    Full Text Available Concept map is a tool for representing knowledge. They have been used in many different fields, including knowledge management, business and industrial design. Concept maps also have been used as an effective learning tool to help students integrate new concepts into their existing set of knowledge. In this study we propose a concept map construction and rule-based evaluation system that is being deployed on the web. After students learned course content to construct individual concept maps for a particular topic that was presented in a course, they can then use the rule-based evaluation system to grade their concept maps against the concept map created by the course instructor. They are also useful for evaluating student learning and helping to illuminate where learning has mastered and where invalid or incomplete ideas are held by the student.

    2015-10-15

    Genome-wide association studies (GWAS) have identified thousands of robust and replicable genetic associations for complex disease. However, the identification of the causal variants that underlie these associations has been more difficult. This problem of fine-mapping association signals predates GWAS, but the last few years have seen a surge of studies aimed at pinpointing causal variants using both statistical evidence from large association data sets and functional annotations of genetic variants. Combining these two approaches can often determine not only the causal variant but also the target gene. Recent contributions include analyses of custom genotyping arrays, such as the Immunochip, statistical methods to identify credible sets of causal variants and the addition of functional genomic annotations for coding and non-coding variation to help prioritize variants and discern functional consequence and hence the biological basis of disease risk.

    Full Text Available Apesar da ampla utilização do conceito de qualidade conjugal, identifica-se falta de clareza conceitual acerca das variáveis que o compõem. Esse artigo apresenta revisão da literatura na área com o objetivo de mapear o conceito de qualidade conjugal. Foram analisadas sete principais teorias sobre o [...] tema: Troca Social, Comportamental, Apego, Teoria da Crise, Interacionismo Simbólico. Pelos postulados propostos nas diferentes teorias, podem-se identificar três grupos de variáveis fundamentais na definição da qualidade conjugal: recursos pessoais dos cônjuges, contexto de inserção do casal e processos adaptativos. Neste sentido, a qualidade conjugal é resultado do processo dinâmico e interativo do casal, razão deste caráter multidimensional. Abstract in english Despite the wide use of marital quality concept, it is identified a lack of variables conceptual clarity. This article presents an area literature review with the objective of mapping out the conjugal concept. Seven theories about this subject were analysed: Social Exchange Theory, Behaviourist Theo [...] ry, Attachment Theory, Crisis Theory, Simbolic Interactionism Theory, Family Systems Theory, Adaptation of Vulnerability to Stress Model. It is possible to identify three groups of variables in the definition of conjugal quality: spouses personal resources, context in which the couple is inserted, adapting processes. Hence, conjugal quality is the result of couple dynamic and interactive process, consequence of a multidimensional character.

    Full Text Available 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 behaviourism 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.

    Even though comprehension of human physiology is crucial in the clinical setting, students frequently learn part of this subject using rote memory and then are unable to transfer knowledge to other contexts or to solve clinical problems. This study evaluated the impact of articulating the concept map strategy with the mediated learning experience on meaningful learning during the cardiovascular module of a medical physiology course at Universidad Autónoma de Bucaramanga. This research was based on the ideas of David Ausubel (meaningful learning), Joseph Novak (concept maps), and Reuven Feuerstein (mediated learning experience). Students were randomly allocated to either an intervention group (mediated learning experience articulated with concept mapping) or a control group (traditional methodology). The intervention group constructed concept maps related to cardiovascular physiology and used them to solve problems related to this subject. The control group attended traditional discussion sessions and problem-solving sessions. All students were evaluated with two types of exams: problem-solving and multiple-choice exams. The intervention group performed significantly better on the problem-solving exams, but the difference was not significant in the multiple-choice exam. It was concluded that intervention promoted meaningful learning that allowed the students to transfer this knowledge to solve problems. The implemented strategy had a greater impact on the students who came into the study with the lowest cognitive competence, possibly because they were empowered by the intervention. PMID:19047509

    Concept mapping is a tool to assist in strategic planning that allows planners to work through a sequence of phases to produce a conceptual framework. Although several studies describe how concept mapping is applied to various public health problems, the flexibility of the methods used in each phase of the process is often overlooked. If practitioners were more aware of the flexibility, more public health endeavors could benefit from using concept mapping as a tool for strategic planning.

  14. Analysis of the psychometric properties of two different concept-map assessment tasks

    Science.gov (United States)

    Plummer, Kenneth James

    The ability to make sense of a wide array of stimuli presupposes the human tendency to organize information in a meaningful way. Efforts to assess the degree to which students organize information meaningfully have been hampered by several factors including the idiosyncratic way in which individuals represent their knowledge either with words or visually. Concept maps have been used as tools by researchers and educators alike to assist students in understanding the conceptual interrelationships within a subject domain. One concept-map assessment in particular known as the construct-a-map task has shown great promise in facilitating reliable and valid inferences from student concept-map ratings. With all of its promise, however, the construct-a-map task is burdened with several rating difficulties. One challenge in particular is that no published rubric has been developed that accounts for the degree to which individual propositions are important to an understanding of the overall topic or theme of the map. This study represents an attempt to examine the psychometric properties of two construct-a-map tasks designed to overcome in part this rating difficulty. The reliability of the concept-map ratings was calculated using a person-by-rater-by-occasion fully crossed design. This design made it possible to use generalizability theory to identify and estimate the variance in the ratings contributed by the three factors mentioned, the interaction effects, and unexplained error. The criterion validity of the concept-map ratings was examined by computing Pearson correlations between concept-map and essay ratings and concept-map and interview transcript ratings. The generalizability coefficients for student mean ratings were moderate to very high: .73 and .94 for the first concept-mapping task and .74 and .87 for the second concept-mapping task. A relatively large percentage of the rating variability was contributed by the object of measurement. Both tasks correlated highly with essay and interview ratings: .62 to .81.

  15. Inception horizon concept as a basis for sinkhole hazard mapping

    2012-04-01

    The office for natural hazards of the Vaud canton (Switzerland) is interested for a pragmatic approach to map sinkhole hazard in karst areas. A team was created by merging resources from a geoengineering company (CSD) and a karst specialist (SISKA). Large areas in Vaud territory are limestone karst in which the collapse hazard is essentially related to the collapse of soft-rocks covering underground cavities, rather than the collapse of limestone roofs or underground chambers. This statement is probably not valid for cases in gypsum and salt. Thus, for limestone areas, zones of highest danger are voids covered by a thin layer of soft-sediments. The spatial distributions of void and cover-thickness should therefore be used for the hazard assessment. VOID ASSESSMENT Inception features (IF) are millimetre to decimetre thick planes (mainly bedding but also fractures) showing a mineralogical, a granulometrical or a physical contrast with the surrounding formation that make them especially susceptible to karst development (FILIPPONI ET AL., 2009). The analysis of more than 1500 km of cave passage showed that karst conduits are mainly developed along such discrete layers within a limestone series. The so-called Karst-ALEA method (FILIPPONI ET AL., 2011) is based on this concept and aims at assessing the probability of karst conduit occurrences in the drilling of a tunnel. This approach requires as entries the identification of inception features (IF), the recognition of paleo-water-table (PWT), and their respective spatial distribution in a 3D geological model. We suggest the Karst-ALEA method to be adjusted in order to assess the void distribution in subsurface as a basis for sinkhole hazard mapping. Inception features (horizons or fractures) and paleo-water-tables (PWT) have to be first identified using visible caves and dolines. These features should then be introduced into a 3D geological model. Intersections of HI and PWT located close to landsurface are areas with a high probability of karst occurrence. ASSESSMENT OF THE SOFT-SEDIMENT COVER Classical geological investigations (mapping, DEM analysis, drilling, etc.) are used to establish a map of the thickness of soft-sediment on top of the limestone. This can also be included in the 3D model. The combination of the void and soft-sediment information in the 3D model makes it possible to derive the sinkhole hazard map. This is currently being developed and applied in the Vaud canton and first results will be presented. BIBLIOGRAPHY FILIPPONI, M., JEANNIN, P. & TACHER, L.

    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.

  9. A new strategy for developing Vs30 maps

    Science.gov (United States)

    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.

  10. Enriching traditional biology lectures digital concept maps and their influence on cognition and motivation

    Directory of Open Access Journals (Sweden)

    Steffen Schaal

    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.

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

    International Nuclear Information System (INIS)

    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 commutators and allows an explicit construction of the (2 x 2)-dimensional blocks. As an important application of unambiguous state discrimination, unambiguous state comparison, i.e., the question whether two states are identical or not, is generalized and optimal measurements for this problem are constructed. If for a certain family of states, a physical device maps the input state to an output state, such that a second device can be built that yields back the original input state, such a map is called reversible on this family. With respect to state discrimination, such reversible maps are particularly interesting, if the output states are pure. A complete characterization of all families that allow such a reversible and purifying map is provided. If the states are mapped to pure states, but the map itself is not reversible, upper and lower bounds are analyzed for the ''deviation from perfect faithfulness'', a quantity which measures the deviation from a reversible mapping.

We show that concept maps used to structure scientific writing and clarify scientific reasoning do not adhere to this notion. In an undergraduate course for thesis writers, students use concept maps instead of traditional outlines to define the boundaries and scope of their research and to construct an argument for the significance of their research. Students generate maps at the beginning of the semester, revise after peer review, and revise once more at the end of the semester. Although some students revised their maps to make them more complex, a significant proportion of students simplified their maps. We found no correlation between increased complexity and improved scientific reasoning and writing skills, suggesting that sometimes students simplify their understanding as they develop more expert-like thinking. These results suggest that concept maps, when used as an intervention, can meet the varying needs of a diverse population of student writers. PMID:26538388

    Joseph Novak, the inventor of concept maps, explains in this interview how that idea was born thirty years ago. As a student he developed a passion for education, trying to find better ways to educate people and help them "learn how to learn". Concept maps can profitably be used to represent knowledge in every field of study: they help students to construct new learning and are also useful for teachers to discover possible misconceptions in the students' own construction. Novak discusses the advantages of meaningful learning and the foundations of his theory of education based on "human constructivism" and he summarizes it in a concept map. He also explains why concept maps are a useful tool for corporations, too.

  15. Utilization Practice of the Concept Mapping Program for Nuclear Engineer Training

    International Nuclear Information System (INIS)

    Knowledge is the most important factor in the safe and reliable operation of the NPP. Many methods are used to enhance the knowledge level of the personnel in the NPP. Generally, classroom lecture method is used for nuclear engineers. But this method has some pitfalls as an adult training method because students have already a lot of knowledge, so they want to participate actively in the learning process. KNPEI undertook a research project from March 2006 to September 2007 to capture the experience knowledge from senior staff and transfer it to junior staff. As part of the research activity KNPEI introduced a Concept Mapping Program and set up a Concept Mapping server to capture the experience knowledge of the senior staff. This Concept Mapping Program has some characteristics that can be used in learning about conceptual knowledge. The purpose of this report is to introduce the utilization method and practice at KNPEI for the nuclear engineer training using the Concept Mapping Program

    The purpose of this study was to investigate affective outcomes and academic achievement for students enrolled in high school biology when instruction included concept-mapping. The research design was quasi-experimental and allowed for a comparison between an experimental group who constructed concept maps and a control group who received traditional biology instruction. The subjects were 140 ninth-grade students, distributed into six intact biology classes, three honors and three general biology classes. Chapter tests and a textbook generated 9-week comprehensive posttest were used to measure achievement. ANCOVA analysis on the comprehensive posttest indicated no significant overall effect of concept mapping on biology achievement across the whole quarter when controlling for the quarter pretest. Chi-square analyses were performed to measure students' attitude toward biology class and activities. The experimental group indicated higher than expected tendency to be positive about the instructional methods, however, the control group indicated fewer than expected positive responses. T-tests were conducted to determine the differences between the experimental and control groups on chapter tests with or without concept mapping. The group with concept mapping scored significantly better than those with traditional methods. Honors class comparisons indicated a significant difference between groups at p<.05 level on the chapter pretest. There was also a significant difference on the chapter test after intervention, but this time at p<.001 level. Although the general class comparisons indicated no significant difference on the chapter pretest, the experimental group scored significantly better than the control group on the chapter test following intervention. This suggests that average ability students benefit from concept mapping more than traditional instruction. In narrative self-evaluations, only a small percentage of participants overall listed concept mapping as the review activity that helped them learn most. Recommendations for practitioners and future research were provided related to the use of concept mapping.

  4. Discovering Concept Mappings by Similarity Propagation among Substructures

    Science.gov (United States)

    Pan, Qi H.; Hadzic, Fedja; Dillon, Tharam S.

    Concept matching is important when heterogeneous data sources are to be merged for the purpose of knowledge sharing. It has many useful applications in areas such as schema matching, ontology matching, scientific knowledge management, e-commerce, enterprise application integration, etc. With the desire of knowledge sharing and reuse in these fields, merging commonly occurs among different organizations where the knowledge describing the same domain is to be matched. Due to the different naming conventions, granularity and the use of concepts in different contexts, a semantic approach to this problem is preferred in comparison to syntactic approach that performs matches based upon the labels only. We propose a concept matching method that initially does not consider labels when forming candidate matches, but rather utilizes structural information to take the context into account and detect complex matches. Real world knowledge representations (schemas) are used to evaluate the method.

    A new space-domain operator based on the shape function concept of finite element analysis has been developed to derive the residual maps of the Gorda Plate of western United States. The technique does not require explicit assumptions on isostatic models. Besides delineating the Gorda Plate boundary, the residual maps exhibit a close match both in their anomaly patterns and magnitudes with previously computed residual maps based on the theory of isostasy.

  6. Concept maps as organizers in an introductory university level biology course

    Science.gov (United States)

    Salata, Mark Walter A.

    The purpose of this study was to determine whether or not a concept map organizer improved recall of lecture material in an introductory university biology course to a statistically significant degree over an outline organizer. It is important that students learn the multiple connections between concepts even within one lecture. The concept map organizer provides a visual display that shows the multiple connections in an explicit manner as opposed to a list of terms shown in an outline. A one-between, two-within, repeated measures design was used to assess student achievement when presented with both types of lectures-organized either by an outline or concept map. An analysis of variance was performed on the data collected with 170 students included in the sample out of a population of approximately 466. In addition, a survey was given three months after the pre- and post-test data were collected. The survey was constructed to ask the participants to recall the lecture organizers used in the study, their preference of organizer, and belief in the organizers' usefulness as a learning tool. A control population was asked to choose their preference of organizer and belief in the organizers' usefulness as a learning tool. It was found that achievement improved to a statistically significant and meaningful level when students were presented lectures using a concept map organizer. Achievement was higher when students were shown lectures using the concept map organizer as compared to the outline organizer. The participants preferred a mixture of organizers for lecture presentations and believed that the concept map was more useful than the outline. The control group preferred the outline and believed that the outline was more useful as a learning tool. It is recommended, as a result of this study, that more lectures be organized in the form of a concept map at the introductory university level in biology.

This study examined the use of concept maps (a meta cognitive technique to aid reading comprehension of Iranian pre- intermediate L2 learners in one of the language institutes in Shiraz. The researcher wanted to find appropriate answers to the following research questions 1 does the application of concept mapping technique have any significant effect on Iranian pre-intermediate L2 reading comprehension 2 do Iranian pre-intermediate L2learners have positive attitude toward the application of concept maps in their reading classes? For this, 30 pre-intermediate L2 learners were selected and assigned as experimental group. This experimental group received instruction on how to use concept mapping technique as a pre-reading activity. This group took part in language classes twice a week for one hour and half and reading activities covered thirty minutes of the whole class and also they completed two thirty-minutes reading comprehension tests, one as the pre-test and the other as the post-test. The results of Wilcoxon Sign Rank test showed that the participants in concept mapping group performed better in post-test than in pre-test administration. Moreover, the results of Chi-square revealed that, on the whole, L2 learners had positive attitudes toward using concept mapping technique in reading classes. This study had theoretical as well as pedagogical implication in the field of second/ foreign teaching and learning.

    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.

  3. Utilization of Concept Mapping Program at the Root Cause Analysis of Events

    International Nuclear Information System (INIS)

    KHNP introduced the Corrective Action Program (CAP) as a part of the nuclear operation innovation. The Key program of the CAP is the Root Cause Analysis (RCA) program. The RCA is a technique to extract root causes and take actions to prevent a recurrence in the event that management doesn't want it to happen again. KHNP establishes a temporary team for RCA of some event. KHNP should assign some human resources to the temporary team. KNPEI introduced a RCA training program from Comanche Peak Steam Electric Station in 2005 and began training the engineers from 2006. But the RCA Program doesn't operate well at the stations because of two reasons. KNPEI performed a research project from March 2006 to September 2007 to capture experience knowledge from seniors and transfer it to juniors. As part of the research activity KNPEI introduced a Concept Mapping Program and set up a Concept Mapping server to capture experience knowledge. Originally, the Concept Mapping Program was to teach conceptual knowledge by remote. But this Concept Mapping Program has some characteristics that can be used in root causes analysis. The purpose of this report is to suggest the utilization method in root causes analysis in the Concept Mapping

Experiences show that the technique of concept mapping is frequently unfamiliar tostudents. More time would be needed for practising and using it in different learning situations.

  7. Survey and comparison of nuclear power strategy and concepts worldwide

    International Nuclear Information System (INIS)

    The steady growth of the world's population and the enhancement of the standard of living will make the demand for energy grow correspondingly. Not only for economic reasons, but also in the interest of the environment and the global climate will strategies for meeting the global energy demand have recourse to nuclear energy. One can even expect a renaissance of nuclear technology based on evolutionary and innovative developments, as nuclear energy is the sole energy source offering the potentials of power generation at justifiable technological risk and economic investment, while contributing to curbing CO2 emissions. Nuclear technology transfer to the developing countries however is an important task in this strategy for the future. Transfer of know-how and simpler technical standards are required (common problems, common rules, common products). Also, the development of breeder reactors and high-temperature reactors should be a major objective, in order to fully exploit the nuclear option, i.e. conserve energy resources, and meet the demand for process heat. The wide range of tasks ahead in the development of advanced nuclear reactors requires enhanced cooperation and exchange of information at international level. Experience and capacities of the IAEA make this organisation the proper and sole available global forum for performing the tasks to be fulfilled, and Member Countries of the IAEA should support the organisation also in their own interest.

    2013-06-01

    Testicular germ cell tumors (T-GCTs) are the most common solid tumor in adolescent and young adult men. Due to the success of multidisciplinary management, the prognosis of all stages of T-GCT is quite good. The development of complimentary therapeutic strategies including modern cytotoxic chemotherapy regimens, appropriate utilization of radiotherapy, and timely surgical resection has made T-GCTs the model of a "curative" malignancy. Herein we review the background, epidemiology, and genetics of the disease, as well as an approach to its diagnosis and staging, including rationale for managing T-GCT in its various stages. In summary, while some areas in T-GCT care are debated, the vast majority of patients should be approached in a standardized manner which ensures optimal oncologic outcomes and minimal therapeutic morbidity.

The strategy map represents a general and structured framework for strategic objectives and plays an important role in forming competitive advantages for organizations. It is important to find important factors influencing strategy map and prioritize them based on suitable factors. In this paper, we propose an integration of BSC and Fuzzy DEMATEL technique to rank different items influencing strategy of a production plan. The proposed technique is implemented for real-world case study of glass production.

  11. The Concept of Resilience from a Normative Perspective: Examples from Dutch Adaptation Strategies

    Directory of Open Access Journals (Sweden)

    2013-06-01

    Full Text Available Both in academic literature and political practice, resilience is becoming a central evaluative concept for assessing climate adaptation policies. This makes sense because society's main challenge in an altering the environment is to adapt to the inevitable changes. However, applying the concept of resilience to devise adaptation strategies reveals that social-ecological resilience acquires different meanings depending on the social context. There is no straightforward application of resilience. In this contribution, it will be argued that giving meaning to the concept of resilience in adaptation strategies requires making normative choices. These choices concern whether there is a public interest in adaptation, the distribution of private and public responsibilities, and striking a balance between individual rights and general interests. Because these normative choices can be questioned and revised, it is important that they are made explicit to enable a democratic debate on the direction that adaptation strategies should take. Simply referring to the concept of resilience in an adaptation strategy does not suffice, but occludes this discussion. Through formulating and applying a condensed scheme of politico-theoretical approaches that underpin diverging adaptation approaches, this contribution reveals the various underlying normative assumptions and explicates the relevant political choices. Three Dutch adaptation strategies serve as empirical examples. They illustrate the importance of the societal context in giving meaning to resilience in the development of adaptation strategies.

    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. This M.I. was used among sixth grade primary school and first grade secondary school in some state assisted schools in the North of Argentina (Tucumán and Jujuy. After evaluation, the results showed great and positive changes among the experimental groups taking into account the attitude and the academic results. Meaningful Learning was shown through pupil?s creativity, expressions and also their ability of putting this into practice into everyday life.

  13. Concepts and strategy of functional food science: the European perspective.

    Roberfroid, M B

    2000-06-01

    Recent knowledge supports the hypothesis that, beyond meeting nutrition needs, diet may modulate various functions in the body and play detrimental or beneficial roles in some diseases. Concepts in nutrition are expanding from emphasis on survival, hunger satisfaction, and preventing adverse effects to emphasizing the use of foods to promote a state of well-being and better health and to help reduce the risk of disease. In many countries, especially Japan and the United States, research on functional foods is addressing the physiologic effects and health benefits of foods and food components, with the aim of authorizing specific health claims. The positive effects of a functional food can be either maintaining a state of well-being and health or reducing the risk of pathologic consequences. Among the most promising targets for functional food science are gastrointestinal functions, redox and antioxidant systems, and metabolism of macronutrients. Ongoing research into functional foods will allow the establishment of health claims that can be translated into messages for consumers that will refer to either enhanced function or reduction of disease risk. Only a rigorous scientific approach that produces highly significant results will guarantee the success of this new discipline of nutrition. This presents a challenge for the scientific community, health authorities, and the food industry. PMID:10837311

    2015-02-20

    The relationship between DNA and protein sequences is well understood, yet because the members of a protein family/subfamily often carry out the same biochemical reaction, elucidating their individual role in cellular processes presents a challenge. Forward and reverse genetics have traditionally been employed to understand protein functions with considerable success. A fundamentally different approach that has gained widespread application is the use of small organic molecules, known as chemical genetics. However, the slow time-scale of genetics and inherent lack of specificity of small molecules used in chemical genetics have limited the applicability of these methods in deconvoluting the role of individual proteins involved in fast, dynamic biological events. Combining the advantages of both the techniques, the specificity achieved with genetics along with the reversibility and tunability of chemical genetics, has led to the development of a powerful approach to uncover protein functions in complex biological processes. This technique is known as allele-specific chemical genetics and is rapidly becoming an essential toolkit to shed light on proteins and their mechanism of action. The current review attempts to provide a comprehensive description of this approach by discussing the underlying principles, strategies, and successful case studies. Potential future implications of this technology in expanding the frontiers of modern biology are discussed. PMID:25436868

    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.

    2009-01-01

    Full Text Available The discovery of X-rays by Roentgen in 1895 and the discovery of radiations emitted from Uranium compounds by Becquerel led to the establishment of the field of Radiation Sciences. When Radiation Sciences utilized the knowledge in the field of Physics, Chemistry, Biology and Medicine, newer fields were established such as Radiation -Oncology, -Chemistry, -Biology, -Protection, - Physics, Radiology and Nuclear Medicine. Fields of Radiation Oncology and Radiation Biology have gained significant strides by embracing the modern concepts in molecular biology and physics of imaging. To discuss the recent trends and advances in these fields, Indian Society for Radiation Biology organized an “International Conference on Radiation Biology and Translational Research in Radiation Oncology (ICRB-TRRO” in Jaipur, India during November 10-12, 2008. The primary theme of this international meeting was to focus on the translational research perspectives in radiation oncology using radiation biology findings as a reservoir of ideas. The second major theme was to focus on research initiatives and recent perspectives in radiation protection. A common dynamic theme constantly interacted with the primary and secondary themes was an influx of extensive discussion on the scientific utility and validity of novel agents obtained from different traditional systems of Indian medicine and herbal plant extracts that can be potent radio-sensitizers as well as potent radio-protectors (as countermeasure agents. Overall, four major thrust areas of the conference such as Radiation-induced signaling networks, novel therapeutics for cancer,radiation-induced DNA damage-repair and novel imaging methods provided new insights and directions that had set roads to advancements in radiation biology.

  8. Radiation treatment of brain tumors: Concepts and strategies

    International Nuclear Information System (INIS)

    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

    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.

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.

  14. An analysis of strategies used by chemistry instructors to address student alternate conceptions in chemical equilibrium

    Science.gov (United States)

    Piquette, Jeff Stephen

    This study explored general-chemistry instructors' awareness of and ability to identify common student alternate conceptions in chemical equilibrium. Instructor strategies directed at remediation of student alternate conceptions were also investigated and compared to successful, literature-based conceptual change methods. Fifty-two general chemistry instructor volunteers from 50 U.S. colleges and universities completed an interactive web-based survey that gathered their responses to open-ended questions, a rating scale, classroom scenarios, and a demographic form. The three scenarios asked respondents to evaluate hypothetical student exam answers, justify their evaluations, and report how they would assist students to better understand ideas about which they held alternate conceptions. Survey respondents who provided responses or remediation strategies that needed further clarification were sampled (n = 6); each amplified their views in an individual, researcher-led semi-structured phone interview. All survey responses and interview transcriptions were independently analyzed by three raters who followed Patton's (1990) guidelines for qualitative data analysis. Data analysis established that all 52 instructors of chemistry were able to report and identify common student alternate conceptions in chemical equilibrium. Those instructor-reported alternate conceptions were congruent with previously identified alternate conceptions (misconceptions) found in published literature, thus providing validation support for the earlier compilations. This study revealed that chemistry instructors employ a variety of strategies in efforts to address and remediate alternate conceptions. However, those strategies rarely include all four conditions outlined by Posner, Strike, Hewson, and Gertzog (1982) needed to stimulate conceptual change in students. Instructors are thus encouraged to become familiar with successful conceptual change strategies, using such methods as appropriate in their classrooms. Study participants offered some speculation about possible sources of student alternate conceptions. Further research into such origins is recommended so student acquisition of alternate conceptions about chemical equilibrium might be anticipated and possibly minimized. The strategy of using web-based technology as a faculty-survey technique was found to be convenient and powerful. Instructors and researchers are encouraged to continue exploring positive and negative aspects of web-based data-gathering techniques in future survey-based educational research.

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

    International Nuclear Information System (INIS)

    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 provided. Finally, the integration of various distinct concepts and modes of information into a concise and logical schema will be demonstrated by means of the CNSC Steam Generator Knowledge Map system.

    This study explores general-chemistry instructors' awareness of and ability to identify and address common student learning obstacles in chemical equilibrium. Reported instructor strategies directed at remediating student alternate conceptions were investigated and compared with successful, literature-based conceptual change methods. Fifty-two volunteer general chemistry instructors from 50 U.S. colleges and universities completed an interactive web-based instrument consisting of open-ended questions, a rating scale, classroom scenarios, and a demographic form. Survey respondents who provided responses or described remediation strategies requiring further clarification were identified (n = 6); these respondents amplified their views in separate, researcher-led semistructured phone interviews. All 52 responding chemistry instructors reported and identified common student areas of difficulty in chemical equilibrium. They reported employing a variety of strategies to address and attempt to remediate students' alternate conceptions; however, these self-reported strategies rarely included all four necessary conditions specified by Posner, Strike, Hewson, and Gertzog (Science Education, 66, 211-217, 1982) to stimulate conceptual change. Instructor-identified student alternate conceptions were congruent with literature-reported alternate conceptions of chemical equilibrium, thus providing validation support for these compilations. Implications for teaching and further research are also highlighted.

  2. Strategic political postures and political market orientation : Towards an integrated concept of political marketing strategy

    DEFF Research Database (Denmark)

    Ormrod, Robert P.; Henneberg, Stephan C.

    2010-01-01

    Recently, the areas of strategic political marketing and political market orientation have been the subject of several conceptual articles which have provided the theoretical foundations for further empirical work. However, despite the close conceptual relatedness of the proposed concepts, these have yet to be integrated to provide a more nuanced framework which both researchers and political marketing practitioners can utilise in the development of strategies and offerings with which to achieve their organizational goals. The aim of this conceptual paper is to address this deficit by developing an integrated concept of political marketing strategy using two complementary frameworks, namely Strategic Political Postures (SPP) and Political Market Orientation (PMO). We introduce the two main concepts and derive for each of the strategic posture-specific PMO profiles as well as inter-construct relationships.

    Khosa, Deep K; Volet, Simone E; Bolton, John R

    2014-01-01

    The value of collaborative concept mapping in assisting students to develop an understanding of complex concepts across a broad range of basic and applied science subjects is well documented. Less is known about students' learning processes that occur during the construction of a concept map, especially in the context of clinical cases in veterinary medicine. This study investigated the unfolding collaborative learning processes that took place in real-time concept mapping of a clinical case by veterinary medical students and explored students' and their teacher's reflections on the value of this activity. This study had two parts. The first part investigated the cognitive and metacognitive learning processes of two groups of students who displayed divergent learning outcomes in a concept mapping task. Meaningful group differences were found in their level of learning engagement in terms of the extent to which they spent time understanding and co-constructing knowledge along with completing the task at hand. The second part explored students' and their teacher's views on the value of concept mapping as a learning and teaching tool. The students' and their teacher's perceptions revealed congruent and contrasting notions about the usefulness of concept mapping. The relevance of concept mapping to clinical case-based learning in veterinary medicine is discussed, along with directions for future research. PMID:25270652

    2011-09-01

    Full Text Available Background & Aim: Most of the recent studies in nursing education have been focused on outcomes of learning. Conventional clinical nursing education, which emphasizes on skill acquisitions, may not encourage students to adopt meaningful or deep learning approaches. This study examined the effect of Concept Mapping on learning approaches among nursing students.Methods & Materials: In this quasi-experimental study, 53 nursing students were randomly divided into two control (n=25 and experimental (n=28 groups. We taught concept mapping for the nurses in the experimental group to use it in caring patients and learning clinical skills. The control group received traditional nursing care plan lessons. Before and at the end of the intervention, the students' approach to learning was assessed using the Study Process Questionnaire. Data was analyzed using independent t test.Results: No statistically significant difference was found between the control and experimental groups on demographics, surface and deep approaches to learning at the beginning of the study (P>0.05. Deep approach to learning increased significantly in the experimental group after the intervention (P=0.03. There was also statistically significant difference in the deep approach to learning between two groups (P=0.02. No statistically significant difference was found in the surface approaches to learning between two groups.Conclusion: The results of this study provided empirical support for the use of concept mapping as a meta cognitive intervention to increase students' meaningful learning and academic achievement.

    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

    The paper presents the implementation of a dense multi-view stereo matching pipeline for the evaluation of image sequences from a camera-based mobile mapping system. For this purpose the software system SURE is taken as a basis. Originally this system was developed to provide 3D point clouds or DEM from standard airborne and terrestrial image blocks. Since mobile mapping scenarios typically include stereo configurations with camera motion predominantly in viewing direction, processing steps like image rectification and structure computation of the existing processing pipeline had to be adapted. The presented investigations are based on imagery captured by the mobile mapping system of the Institute of Geomatics Engineering in the city center of Basel, Switzerland. For evaluation, reference point clouds from terrestrial laser scanning are used. Our first results already demonstrate a considerable increase in reliability and completeness of both depth maps and point clouds as result of the matching process.

  17. Concept-mapping as a teaching method to facilitate critical thinking in nursing education: A review of the literature

    Scientific Electronic Library Online (English)

    Mary M., Chabeli.

    Full Text Available Nursing students are exposed to a vast amount of information and reading material that is very specific, technical, and new to the students. Unless nurse educators provide a learning environment that promotes understanding through interaction, students might only commit unassimilated information to [...] their short-term memory through rote learning, and no meaningful learning will occur. Nursing students must be able to link learned facts, concepts and principles with new knowledge in order to make sound rational decisions in practice (All & Havens 1997:1210, 1213). The aim of this paper is to describe the utilisation of concept-mapping as a teaching method to facilitate critical thinking by students in nursing education. The description of the utilisation of concept-mapping is done from the theoretical framework of concept-mapping and critical thinking to provide the epistemological basis for concept-mapping (Facione 1990:6, 13). Based on the exploration and description of the theoretical frameworks, four steps to facilitate critical thinking were formulated through concept-mapping on the basis of the educational process: the identification, interactive constructing process, formulation and evaluation steps. It is concluded that the utilisation of these steps will assist nurse educators to implement concept-mapping as a teaching method to facilitate critical thinking by student nurses in nursing education. Recommendations are made.

    2006-05-01

    Full Text Available Abstract Background Incorporation of ontologies into annotations has enabled 'semantic integration' of complex data, making explicit the knowledge within a certain field. One of the major bottlenecks in developing bio-ontologies is the lack of a unified methodology. Different methodologies have been proposed for different scenarios, but there is no agreed-upon standard methodology for building ontologies. The involvement of geographically distributed domain experts, the need for domain experts to lead the design process, the application of the ontologies and the life cycles of bio-ontologies are amongst the features not considered by previously proposed methodologies. Results Here, we present a methodology for developing ontologies within the biological domain. We describe our scenario, competency questions, results and milestones for each methodological stage. We introduce the use of concept maps during knowledge acquisition phases as a feasible transition between domain expert and knowledge engineer. Conclusion The contributions of this paper are the thorough description of the steps we suggest when building an ontology, example use of concept maps, consideration of applicability to the development of lower-level ontologies and application to decentralised environments. We have found that within our scenario conceptual maps played an important role in the development process.

    2015-07-01

    Schools of Public Health have a wide variety of essential stakeholders. Broad input in program planning should assist in ensuring well-developed plans and strong community buy-in. The planning of a school can better address the needs of multiple stakeholders from systematic broad-based input from these constituents using concept mapping. In this study, we used concept mapping to prioritize a set of recommendations from diverse stakeholders to assist in the process of planning a school. A set of statements was generated on essential elements for the proposed school from a broad group of stakeholders. The statements were then distilled into unique themes, which were then rated on importance and feasibility. Cluster maps and pattern matches were used to analyze the ratings. Unique themes (N = 147) were identified and grouped into 12 clusters. Cluster themes included leadership, faculty, culture, school, and curriculum. Pattern matches revealed a significant, modest correlation between importance and feasibility (r = 0.27). A broad range of perspectives was used to identify relevant areas to address in the development of a school. PMID:26225267

  8. Recontextualising a Strategic Concept Within a Globalising Company : A Case Study on Carlsberg's ‘Winning Behaviours’ Strategy

    DEFF Research Database (Denmark)

    SØderberg, Anne-Marie

    2015-01-01

    A corporate strategy is often formulated on the executive floor at headquarters. However, in order to make it live in an organisation, middle management and employees must be involved and make sense of it. These actors thus contribute to, participate in and enact the strategy in processes where it may take on new meanings and forms. This article investigates how ‘Winning Behaviours’, a strategic concept developed on the initiative of top management at the Carlsberg Group in order to improve global integration in the multinational organisation, was recontextualised. It draws upon interviews and observations as well as documents collected at the company headquarters in Denmark and in its subsidiaries in China and Malaysia. Here, expatriate and local managers tried to give sense to the Winning Behaviours in various ways, and employees brought their own local leadership ideals into play when they tried to make sense of the preferred behaviours and turn them into daily practices. The process of creating a new strategic concept and making it live in other sociocultural contexts was facilitated by headquarters staff in the Human Resources and Communications departments, who thus played an important role as change agents in the ‘glocal’ strategy process

    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.

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

    International Nuclear Information System (INIS)

    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.

    Miller, J Jay; Jones, Blake

    2015-12-01

    Citizen Review Panels (CRPs) are groups of citizen volunteers authorized by U.S. federal law to examine state child welfare agencies. These groups inspect policies and practices related to child protection responsibilities and are tasked with making recommendations for systemic improvement. Despite the federal mandate for each state to develop a CRP and the potential of these groups to positively impact child welfare practices, there is a dearth in the literature related to CRPs. Consequently, planning and evaluation processes of these groups vary widely. This study reports on the use of concept mapping (CM) to outline a framework for planning and subsequently evaluating the CRP in one southeastern state. CM is a mixed-method research approach that uses multi-dimensional scaling and hierarchical cluster analyses to explore an area of study. Through these analyses, the method creates visual depictions of conceptual relationships between ideas. Data yielded a seven cluster concept map that CRP members (N=36) utilized for planning processes, and subsequently for developing an internal evaluation tool. Results from this study offer a unifying framework by which CRPs, and similar groups in other areas can utilize for planning and evaluation purposes. After a review of pertinent literature on CRPs, this article explicates CM processes utilized in this study, describes results, discusses lessons learned, and outlines apposite areas for future CRP research.

    2006-01-01

    In this paper the attempt is made to emphasize the differences between indigenous education practices and concepts and the Western imposed cultural ethnocentrism in the South East Asian Region. It is my hope that the discussions in the paper will be of interest to scholars and students engaged in development processes in pluri-ethnic societies. The action plans presented in the “Education for All” conferences in 1990 and 2000 are used to illustrate the differences in the concept of education. The plans show that the Western education concept still dominates in the development discourse. These conferences are important as “Education for All” strategies seem to be the main beacon of future development within education, as well as it is significant that other concepts of education than the Western are hardly given any attention in the two declarations. The point is further made that it is not a purely academic discussion, as the West has the institutional power to impose its hegemony in theory and practice. Thisnotwithstanding, a new discourse is emerging within the research community which shows sensitivity to the problems of indigenous communities in the context of Third World development discourse.

    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.

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

    International Nuclear Information System (INIS)

    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)

    For secondary students to make use of astronomical data in a school setting, they previously needed access to large telescopes, expensive equipment and difficult-to-use software. This has improved as online data archives have become available; however, difficulties remain, including searching and downloading the data and translating it into formats that high school students can readily analyze. To address these issues, the NASA/IPAC Teacher Archive Research Program (NITARP) selects teams consisting of teachers and students from several schools. Each year, new teams of educators attend an introductory workshop at the winter AAS conference where they select a research project that will use the archived data. Throughout the spring, educators engage in weekly teleconferences, write proposals, and begin working with their students. The teams meet at Caltech in the summer to learn how to access and analyze the IPAC data and continue to work throughout the fall. Through this experience, participants learn how to search, download, translate, and analyze authentic astronomical data. They learn the nature of scientific communication through developing and presenting their findings alongside practicing astronomers at the following winter AAS. In order to measure how successful the 2014 NITARP summer visit was in teaching participating high school students the terminology and processes necessary to analyze IPAC data, students were asked to create concept maps showing the main and subsidiary ideas and concepts related to their research. They then synthesized their group webs into a master web. When additional terms and concepts were presented, the students were able to integrate them into the master web, showing that they understood the relationship of ideas, concepts, and processes needed for their research. Our companion poster, Gibbs et al., presents the scientific aspects of this project. This research was made possible through the NASA/IPAC Teacher Archive Research Program (NITARP) and was funded by the NASA Astrophysics Data Program.

    The bulk and retail water companies of the greater Melbourne area are developing the 2009 Metropolitan Sewerage Strategy to provide sustainable sewerage services to 2060. The objective of the strategy is to establish long term principles and near term actions to produce a robust sewage management system for Melbourne. Melbourne's existing sewerage system is largely centralised and discharges to two major treatment plants. Several small satellite treatment plants service local urban areas generally more distant from the centralised system. Decentralised and on-site wastewater systems are options for future sewage management and could play a role in local recycling. A portfolio of 18 on-site and decentralised concept designs was developed, applicable to the full range of urban development types in Melbourne. The concepts can be used in evaluation of metropolitan system configurations as part of future integrated water cycle planning. The options included secondary and tertiary treatment systems incorporating re-use of water for non potable uses, urine separation, black and greywater separation and composting toilets. On-site and cluster treatment systems were analysed. Each option is described by its indicative capital and operating costs, energy use and water and nutrient balances. This paper summarises and compares the portfolio mix of decentralized and on-site options in Melbourne's context. PMID:20705997

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

    International Nuclear Information System (INIS)

    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)

    Hypertension, once a rare problem in Sub-Saharan Africa (SSA), is predicted to be a major cause of death by 2020 with mortality rates as high as 75%. However, comprehensive knowledge of provider-level factors that influence optimal management is limited. The objective of the current study was to discover physicians' perceptions of factors influencing optimal management and control of hypertension in SSA. Twelve physicians attending the Cardiovascular Research Training (CaRT) Institute at the University of Ghana, College of Health Sciences, were invited to complete a concept mapping process that included brainstorming the factors influencing optimal management and control of hypertension in patients, sorting and organizing the factors into similar domains, and rating the importance and feasibility of efforts to address these factors. The highest ranked important and feasible factors include helping patients accept their condition and availability of adequate equipment to enable the provision of needed care. The findings suggest that patient self-efficacy and support, physician-related factors, policy factors, and economic factors are important aspects that must be addressed to achieve optimal hypertension management. Given the work demands identified by physicians, future research should investigate cost-effective strategies of shifting physician responsibilities to well-trained no-physician clinicians in order to improve hypertension management.

    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.

  3. Mapping primary constraints in physical asset management strategy execution, using social network analysis

    Scientific Electronic Library Online (English)

    J., Baum; P.J., Vlok.

    Full Text Available The successful execution of a physical asset management strategy is an important value driver for organisations that are highly dependent on the service delivery of physical assets. Research demonstrates that strategic targets are often not met, and that the means to detect the constraints that can [...] undermine strategy execution efforts are deficient. The purpose of this article is to investigate social network analysis (SNA) as a method to map primary constraints in physical asset management strategy execution (PAMSE). As an interim result, the study found that dysfunctional information flow and poor decisionmaking are the primary constraints that can hinder the PAMSE. An SNA application methodology was developed and applied at two research sites in the South African mining industry. This study found that SNA can be used to map constraints experienced in PAMSE; but it also points towards important prerequisites that have to be established for SNA to be successful.

    Concept maps have been used to help students with learning disabilities (LD) improve literacy skills and content learning, predominantly in secondary school. However, despite increased access to classroom technology, no previous studies have examined the efficacy of computer-based concept maps to improve learning from informational text for students with LD in elementary school. In this study, we used a concurrent delayed multiple probe design to evaluate the interactive use of computer-based concept maps on content acquisition with science and social studies texts for Hispanic students with LD in Grades 4 and 5. Findings from this study suggest that students improved content knowledge during intervention relative to a traditional instruction baseline condition. Learning outcomes and social validity information are considered to inform recommendations for future research and the feasibility of classroom implementation. PMID:25301848

    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.

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

    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. This demonstrates that medical students using mind maps can successfully retrieve information in the short term, and does not put them at a disadvantage compared to SNT students. Future studies should explore longitudinal effects of mind-map proficiency training on both short- and long-term information retrieval and critical thinking.

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

    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 essential to resort to the focus group approach to explore deeply a complex subject such as equity, which became, after the two CMs, one of the important topics of the research. Conclusion Using this technique in a new context was not the easiest thing to do. Nevertheless, contrary to what local organizers thought when we explained to them this "crazy" idea of applying the technique in Moore with peasants, we believe we have shown that it was feasible, even with persons not literate in French.

    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.

    In this study, we explored the presentation of clinical depression in Java, Indonesia. Interviews were conducted with 20 Javanese patients (male and female) with major depressive disorder from both lower and higher socioeconomic levels. The recruited participants came from provincial and private mental health hospitals in the cities of Solo, Yogykarta (Jogja), Jakarta, and Malang on the island of Java, Indonesia. Concept mapping methodology using multidimensional scaling and hierarchical cluster analysis was used to identify underlying themes in the expression of depressive phenomena in this Indonesian population. The results identified themes that grouped into six clusters: interpersonal relationships, hopelessness, physical/somatic, poverty of thought, discourage, and defeat. Findings give support to the view that culture influences the expression of Indonesian depressive phenomenology, which nevertheless has some common roots with Western clinical pictures of the disorder. Cultural influences may mask symptoms of the disorder to clinicians. Diagnostic and assessment tools must be carefully selected to ensure they address culturally specific expressions of depression.

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

    International Nuclear Information System (INIS)

    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 results are presented to show the effectiveness of this control strategy. And further discussions are given for items to be evaluated in the future to apply it in the actual reactor control. (author)

    Climate change has been stated as being one of the greatest challenges to global health in the current century. Climate change impacts on human health and the socio-economic and related poverty consequences are however still poorly understood. While epidemiological issues are strongly coupled with environmental and climatic parameters, the social and economic circumstances of populations might be of equal or even greater importance when trying to identify vulnerable populations and design appropriate and well-targeted adaptation measures. The inter-linkage between climate change, human health risk and socio-economic impacts remains an important - but largely outstanding - research field. We present an overview on how risk is traditionally being conceptualised in the human health domain and reflect critically on integrated approaches as being currently used in the climate change context. The presentation will also review existing approaches, and how they can be integrated towards adaptation tools. Following this review, an integrated risk concept is being presented, which has been currently adapted under the EC FP7 research project (HEALTHY FUTURES; http://www.healthyfutures.eu/). In this approach, health risk is not only defined through the disease itself (as hazard) but also by the inherent vulnerability of the system, population or region under study. It is in fact the interaction of environment and society that leads to the development of diseases and the subsequent risk of being negatively affected by it. In this conceptual framework vulnerability is being attributed to domains of lack of resilience as well as underlying preconditions determining susceptibilities. To fulfil a holistic picture vulnerability can be associated to social, economic, environmental, institutional, cultural and physical dimensions. The proposed framework also establishes the important nexus to adaptation and how different measures can be related to avoid disease outbreaks, reduce 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.

    In the upcoming generation of satellite sensors, hyperspectral instruments will play a significant role. This payload type is considered world-wide within different future planning. Our team has now successfully finalized the Phase B study for the advanced hyperspectral mission EnMAP (Environmental Mapping and Analysis Programme), Germans next optical satellite being scheduled for launch in 2012. GFZ in Potsdam has the scientific lead on EnMAP, Kayser-Threde in Munich is the industrial prime. The EnMAP instrument provides over 240 continuous spectral bands in the wavelength range between 420 and 2450 nm with a ground resolution of 30 m×30 m. Thus, the broad science and application community can draw from an extensive and highly resolved pool of information supporting the modeling and optimization process on their results. The performance of the hyperspectral instrument allows for a detailed monitoring, characterization and parameter extraction of rock/soil targets, vegetation, and inland and coastal waters on a global scale supporting a wide variety of applications in agriculture, forestry, water management and geology. The operation of an airborne system (ARES) as an element in the HGF hyperspectral network and the ongoing evolution concerning data handling and extraction procedures, will support the later inclusion process of EnMAP into the growing scientist and user communities.

    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 ?elds such as biotechnology, medicine and pharmacology.

    Performance attributes of the product, such as robustness, reliability and safety are widely acknowledged as relevant considerations through the design process. Yet they are more important in early design stages to ensure the feasibility of design requirements and reduce later design rework in the product lifecycle. This influence is due to the available room for making decisions, together with the cascading effects of these through downstream design activities [Andreasen & Olesen, 1990]. Prior studies revealed the incompleteness of information from early stages for using current methods for robustness, reliability and safety, which also confirmed the problem of the extensive resource requirements in their use [Marini, Restrepo & Ahmed, 2010]. In response to this conclusion, a longitudinal study was performed in collaboration with the manufacturer of an insulin injection pen. This study followed the development of 20 solution alternatives for a new design of such device. This paper aims to describe the influence of design decisions and feedback originated from failures in solution alternatives during the concept development activity. It identifies the characteristics of the development process that influence practices in decision-making and feedback, and it discusses strategies to evaluate and mitigate failures in solution alternatives.

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

    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.

  8. 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

    A primary objective of the upcoming dark energy surveys LSST, Euclid, and WFIRST is to map the 3D distribution of matter over a significant fraction of the universe via the weak lensing cosmic shear field. Doing so will require accurate distance estimates to billions of faint galaxies, meaning that photo-z's will be essential for the ultimate scientific success of these missions. Because galaxy colors drive photo-z estimates, spectroscopic calibration samples must at least be representative in color. Here we present a technique, based on the self-organizing map (Kohonen 1990), to map the empirical distribution of galaxies in the high-dimensional color space of a given survey. We apply the technique to Euclid-like data for ~131k galaxies from the COSMOS survey, allowing us to determine where - in galaxy color space - spectroscopic coverage exists and where it is systematically missing. We show that the mapping technique lets us develop efficient spectroscopic sampling strategies to measure the color-redshift relation by focusing effort on poorly constrained regions of multicolor space. We discuss the nature of the galaxies in un-sampled regions of galaxy color space, and show that a fiducial survey with Keck (making use of LRIS, DEIMOS, and MOSFIRE) could meet the Euclid calibration requirements in ~40 nights of observing.

    In this article, driving forces mapping, a technique derived from business strategy, is applied to five different client situations: an AIDS support organization, a men's bereavement group, an individual managing grief after abortion following diagnosis of a fetal anomaly, an individual dealing with an HIV diagnosis, and a couple who wanted to increase marital satisfaction. The technique was found to be helpful in goal definition, contracting and developing mutuality, and it was less helpful in introspective work. The article describes the work in ways that allow the reader to understand the process and apply the technique. PMID:12555824

    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.

    Full Text Available Higher Education is currently undergoing relentless change worldwide in order to respond effectively to the aspirations of the 21st century. Consequently, prevalent literature in Higher Education calls for more emphasis on the students? learning process through increased metacognition and critical reflection. This paper starts off with the assumption that learning takes place through the integration of thinking, feeling and acting. As a result, this paper will present a model of teaching and learning in Higher Education through the integrated use of Vee Heuristics and Concept Mapping. This research will suggest that when using Concept Maps, Vee Heuristics along with an awareness of how students prefer to learn, the students will go through a metacognitive learning process which would eventually lead to critical reflection and meaningful learning. Using University students? work products, this study traces the effect of a learner?s mental operations on the learner?s use of Vee Heuristics and Concept Mapping as the learner embeds and retrieves new and scaffolded knowledge. The data collected reveals the powerful effect which this combination of learning tolos yielded on student achievement and transformation.

    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. Th...

    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)

    To help manage chronic and cumulative impacts of human activities on marine mammals, the National Oceanic and Atmospheric Administration (NOAA) convened two working groups, the Underwater Sound Field Mapping Working Group (SoundMap) and the Cetacean Density and Distribution Mapping Working Group (CetMap), with overarching effort of both groups referred to as CetSound, which (1) mapped the predicted contribution of human sound sources to ocean noise and (2) provided region/time/species-specific cetacean density and distribution maps. Mapping products were presented at a symposium where future priorities were identified, including institutionalization/integration of the CetSound effort within NOAA-wide goals and programs, creation of forums and mechanisms for external input and funding, and expanded outreach/education. NOAA is subsequently developing an ocean noise strategy to articulate noise conservation goals and further identify science and management actions needed to support them. PMID:26610985

    Full Text Available El surgimiento de nuevos mercados, el e-business, la evolución de nuevas tecnologías, el nivel de competitividad organizacional, la globalización o totalización, no dejan lugar a dudas que el conocimiento representa una de las variables más críticas para lograr el éxito sostenible en cualquier organ [...] ización (Argyris y Schön, 1978; Nonaka, 1991; Kogut y Zander, 1992; entre otros). Uno de los retos más acuciantes para las organizaciones es incrementar su rendimiento en innovación, estamos viviendo una "economía del conocimiento" en la que justamente el conocimiento tiene que convertirse tangiblemente en una innovación, para permitirle a las organizaciones seguir siendo competitivas. En este escrito la autora presenta un análisis para determinar el grado de correlación entre la innovación y la estrategia de las organizaciones, dado que parecen ser conceptos contradictorios: estrategia implica planear e innovación implica inventar "sin orden aparente". A partir de este factor se propone un nuevo punto de vista en relación a los contextos organizacionales adecuados, en función de la estrategia, para obtener un mejor rendimiento de innovación, a través de un estudio realizado en empresas del estado de Guanajuato, México. La metodología es elaborada tomando como base el paradigma constructivista, basado en la "Reconstrucción de la Totalidad" (Páramo, 1999). De acuerdo con los cálculos realizados, se encontró un coeficiente de correlación significativo de 37% entre innovación y estrategia, basada en la escuela de aprendizaje. Se realizó la prueba de normalidad de los residuos, determinando que los datos se comportan de manera normal con un p-value de 58%. Asimismo, se realizaron las encuestas a los equipos de I+D+i de las empresas de la muestra. En conclusión, se señala que en las empresas guanajuatenses el contexto más propicio para detonar la innovación es una estrategia basada en el aprendizaje, organizaciones que aprenden con el tiempo y que a través del mismo convergen en patrones de conducta que funcionan; el coeficiente de correlación encontrado indica una solidez positiva entre innovación y estrategia en el contexto de aprendizaje. Los investigadores que simpatizan con el enfoque de aprendizaje descubrieron que, cuando tenía lugar una reorientación estratégica significativa, raras veces se originaba en una actividad de planificación formal; en realidad muchas veces ni siquiera venía de las oficinas de los directivos superiores (Mintzberg, 1999). Abstract in english The emergence of new markets, e-business, the development of new technologies, the level of organizational competitiveness, the globalization or aggregation, no doubt that the knowledge is one of the most critical variables to achieve sustainable success in any organization (Argyris y Schon, 1978; N [...] onaka, 1991; Kogut y Zander, 1992; among others). One of the most pressing challenges for organizations is to increase its performance of innovation; we have been living a "knowledge economy" that just the knowledge has to become tangibly in an innovation to allow organizations to remain competitive. In this paper the author presents an analysis to explain the degree of correlation between innovation and strategy on the organizations, since they seem to be contradictory concepts: strategy involves planning and innovation involves inventing "without an apparent order". From this perspective, a new point of view in relation to the contexts of the organizations might be considered, in function of the strategy, to obtain a better performance of innovation, through a study conducted on Guanajuato State, Mexico. The methodology is developed based on the constructivist paradigm; it was based methodologically on the "Reconstruction of the Whole" (Páramo, 1999). In the estimates made, it was finding a 37% between innovation and strategic, with the learning school.

  2. Exploring Strategies for Improving Land Cover and Vegetation Mapping Accuracy in Arctic Alaska

    2010-12-01

    Large-area Landsat-derived vegetation and land cover mapping efforts in Arctic Alaska must overcome a number of obstacles presented by the region’s short snow-free season, frequent cloud cover, rapidly changing vegetation phenology, and paucity of in situ vegetation data. The short snow-free season and frequent cloud cover result in a limited number of available cloud-free, snow-free Landsat scenes, and in order to obtain full regional coverage, scenes acquired anytime between June and early September may be used in image mosaics. Consequently, regional image mosaics consist of scenes acquired under a wide variety of solar illumination conditions with widely varying vegetation phenology in which similar vegetation communities or land cover types exhibit major differences in spectral characteristics throughout the mosaic. When extensive training data are available for each component scene of a mosaic, machine learning algorithms are typically able to account for these differences in spectral characteristics and make accurate vegetation predictions across the entire mosaic. In Arctic Alaska, however, training data are only available at a few locations and the cost for acquiring additional training data can be prohibitive. This research explores several strategies for improving fractional shrub cover mapping accuracy in Arctic Alaska that should also be applicable for land cover mapping. The strategies include radiometric normalization using Landsat/MODIS image fusion, topographic illumination correction, addition of topographic data variables, and inclusion of Landsat-derived textural and shape characteristics. Results indicate that, while each strategy alone can boost accuracy slightly, combining the strategies produces the best results. Results also confirm that superior accuracy is obtained when training data is available for each component scene of the image mosaic. This reinforces the need for additional moderate to high spatial resolution (< 100 m) imagery collection over Arctic Alaska which would increase the number of scenes with extensive cloud-free areas, reduce the number of scenes required to build cloud-free regional mosaics, and consequently increase the feasibility of building mosaics with training data available for each component scene.

    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 community. Conclusions: Many community members noted a need and desire for safer conception education and services in Kisumu. However, community barriers such as fear, stigma and lack of information should be addressed before safer conception interventions can be successfully implemented and delivered. Further research focused on community education, male engagement and healthcare provider training is a crucial next step in delivering safer conception in this region.

    Brown, David Scott

    2000-10-01

    Student learning about photosynthesis and cellular respiration was measured after instruction involving individual, group or no concept mapping. This study involved 304 high school Biology students from three different Biology courses in a Mid-west high school. Students were classified as low, medium or high level of academic achievement. The control group consisted of 117 students who did not construct concept maps during a three-week unit on Photosynthesis and Cellular Respiration. The first of two experimental groups consisted of 92 students who created individual maps and the second consisted of 95 students who constructed maps in small groups during the unit. Pre- and post-tests were administered to the students using a gain score as the dependent variable. Covariates used in the statistical analysis were the students' Missouri Mastery and Achievement Tests scores, Iowa Test of Basic Skills scores and the students' current math level. Results from the analysis of co-variance showed a significant difference between the academic level of the student and the type of concept mapping on the dependent variable. In high academic level Biology classes, group mapping students obtained significant lower gain scores (M = 2.3) than the control group (M = 4.9). In the medium level Biology classes, group mapping students showed little difference in gain scores (M = 0.7) from the control group (M = 0.8). In the lower-level Biology classes, group mapping students (M = 2.3) showed significantly greater gain scores than those in the control group (M = 0.8). These results indicate that constructing concept maps in small groups can significantly increase the knowledge gained by lower-level students. An opposite effect is seen on high-level students who create concept maps in small groups. Creating concept maps as individuals appears to have no significant effect on achievement scores on the Biology students observed in this study.

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

    International Nuclear Information System (INIS)

    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

    International Nuclear Information System (INIS)

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

    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.

    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.

    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, lack of education/support for physicians regarding pain management, unavailability of multidisciplinary team-based care, prolonged wait times to see specialists. Conclusions Participants depicted factors driving NA utilization among injured workers as complex. Patient-level factors were perceived as most influential on over-utilization, while system-level factors were considered most amenable to intervention. This has implications for intervention design, suggesting that systemic/structural factors should be taken into account in order to address this important health issue.

    The definition of position and number of wells is the most important stage on production strategy selection, since it will affect the reservoir behavior, which influences future decisions. However this process is time-consuming and it is often a trial-and-error approach. Many studies have been made in order to reduce the engineer's effort in this stage, by minimizing the number of simulation runs through proxy models or by automating the whole process, using some optimization algorithm. This work proposes a methodology that integrates genetic algorithm and quality map to automate the production strategy optimization. It is also introduced the concept of genetic modification, which is the procedure to update the quality map according to the wells production of each evaluated strategy. The objective is to improve the evolutionary process, allowing the evaluation of more promising alternatives, improving the chance of obtaining better solutions without a substantial increase in the number of simulations.

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

    Robinson, Michael A.

    2000-01-01

    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.

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

    International Nuclear Information System (INIS)

    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

  6. Fine mapping quantitative trait loci under selective phenotyping strategies based on linkage and linkage disequilibrium criteria

    2009-01-01

    In fine mapping of a large-scale experimental population where collection of phenotypes are very expensive, difficult to record or time-demanding, selective phenotyping could be used to phenotype the most informative individuals. Linkage analyses based sampling criteria (LAC) and linkage disequilibrium-based sampling criteria (LDC) for selecting individuals to phenotype are compared to random phenotyping in a quantitative trait loci (QTL) verification experiment using stochastic simulation. Several strategies based on LAC and LDC for selecting the most informative 30%, 40% or 50% of individuals for phenotyping to extract maximum power and precision in a QTL fine mapping experiment were developed and assessed. Linkage analyses for the mapping was performed for individuals sampled on LAC within families and combined linkage disequilibrium and linkage analyses was performed for individuals sampled across the whole population based on LDC. The results showed that selecting individuals with similar haplotypes to the paternal haplotypes (minimum recombination criterion) using LAC compared to random phenotyping gave at least the same power to detect a QTL but decreased the accuracy of the QTL position. However, in order to estimate unbiased QTL parameters based on LAC in a large half-sib family, prior information on QTL position was required. The LDC improved the accuracy to estimate the QTL position but not significantly compared to random phenotyping with the same sample size. When applying LDC (all phenotyping levels), the estimated QTL effect were closer to the true value in comparison to LAC. The results showed that the LDC were better than the LAC to select individuals for phenotyping and contributed to detection of the QTL Udgivelsesdato: December

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.

    Education is the fundamental process used to develop and maintain the professional skills of physicians. Medical students, residents, and fellows are expected to learn considerable amounts of information as they progress toward board certification. Established practitioners must continue to learn in an effort to remain up-to-date in their clinical realm. Those responsible for educating these populations endeavor to teach in a manner that is effective, efficient, and durable. The study of learning and performance is a subdivision of the field of cognitive science that focuses on how people interpret and process information and how they eventually develop mastery. A deeper understanding of how individuals learn can empower both educators and learners to be more effective in their endeavors. In this article, we review a number of concepts found in the literature on learning and performance. We address both the theoretical principles and the practical applications of each concept. Cognitive load theory, constructivism, and analogical transfer are concepts particularly beneficial to educators. An understanding of goal orientation, metacognition, retrieval, spaced learning, and deliberate practice will primarily benefit the learner. When these concepts are understood and incorporated into education and study, the effectiveness of learning is significantly improved. PMID:26579660

  2. Design concept and testing strategy of a dual functional lithium lead test blanket module for ITER and EAST

    International Nuclear Information System (INIS)

    Liquid lithium lead (LiPb) breeder blankets, including Quasi-Static Lithium Lead (SLL) breeder blanket and the Dual-cooled Lithium Lead (DLL) breeder blanket, are considered by several parties of ITER program as a design option of DEMO blankets for fusion power reactors due to their potential attractiveness of economy, safety and relatively mature technology base. Considering the confliction between the limited ITER resources for TBM (Test Blanket Module) testing and the requirement of various DEMO blanket concepts proposed by Parties, a Dual Functional Lithium Lead (DFLL) TBM concept has been proposed for testing in ITER to demonstrate the technologies of both SLL and DLL blankets concepts, which emphasizes the balance and the consistence between the risk and the attractiveness of blanket technology development. The DFLL-TBM consists of two specific blanket schemes, namely the DLL and SLL schemes, with as similar as possible basic structure and auxiliary systems except for including FCIs and quicker flowing LiPb as coolant in DLL-TBM to achieve a high outlet temperature. The DLL scheme is the major target of the concept. The SLL scheme may be an optional target if the critical issues (e.g. MHD effects and FCI technology) for the DLL scheme could not be solved. The proposed test strategy will allow consecutively validating SLL/DLL blanket concepts, technologies, and design tools. It covers three phases: materials R and D and small-scale out-of-pile mockup testing in loops, middle-scale TBMs testing in EAST, the superconducting tokamak in China, severing as a pre-testing platform for TBM prior to ITER, because the major parameters of EAST are comparable to those of ITER (for EAST, BT 3.5 ? 4T, D-D neutron rate = 1015 ? 1017 n/sec, average heat flux on the FW = 0.1 ? 0.2 MW/m2, port size = 0.97 x 0.53 m2, plasma pulse length = ? 1000 sec), and full-scale consecutive TBMs corresponding to different operation phases of ITER during the first 10 years. Design details on TBM concept, such as structure scenarios, auxiliary systems, performances analyses and testing strategy combining TBMs testing, in sequence and in parallel, in EAST and ITER, are presented in this contribution.

  7. Conception of a method for the creation of volcanic risk index maps

    Science.gov (United States)

    Bion, P.; Van Wyk de Vries, B.; Valentine, G.

    2012-04-01

    Risk index maps are a variant of risk maps, having the advantage of containing unique kinds of information - levels of risk spatially represented - and can therefore be a more effective communication tool than traditional risk maps. Nevertheless, despite their apparent simplicity, their achievement is the result of a complex risk analysis, requiring the consideration of multidisciplinary indicators, expressing different parameters of the physical and human dimensions of the environment and their interactions. The risk index is obtained in three main stages: the definition of hazard and vulnerability indicators, the transformation of the indicators into subindices through mathematical processes (formulation, standardization, weighting), and the combination of the subindices into a final index. As of now, only few attempts of risk quantification have been done, related to landslide, flood or seismic hazards, and those linked to volcanic hazards are very incomplete because of the specificities and complexities of these kinds of events and their effects. Volcanic hazards have the particularity of being of different types, moreover all events can combine together or be combined with other external events (e.g. meteorological), and they can reach and therefore affect extensive areas by different phenomena. The methodology developed here assesses risk levels in regions potentially impacted by volcanic hazards. It incorporates volcanic hazard specificities and nuances of "vulnerability" by integrating the diversity of the environmental components. It analyses the natural and human strengths, weaknesses, opportunities and threats, which are located within the areas potentially "at risk". Consequently, it considers negative but also positive indicators (respectively aggravating and improving the potential consequences), which can be internal but also external to the volcanic hazards. The approach also considers a temporal variability of the events and their direct or indirect associated effects. The developed approach tends to be especially aimed at urban planners, who would possess a new fundamental tool for organizing the territories located "nearby" volcanoes, in which population density is continually increasing. The volcanic risk index maps would give indications on the areas with the highest risk level, and the urban planners would also be able to determine the elements causing such level. This would lead them to the possibility of proposing recommendations and adequate measures to participate to the reduction of vulnerability, in particular in limiting the exposure and the impacts associated with the volcanic hazards, which would consequently reduce the volcanic risks.

  8. 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 encompassing the state of Acre Brazil. Through a comprehensive comparison involving nearly 50 separate analyses, we assess accuracy in aboveground biomass estimates with respect to varying (a) satellite data inputs, (b) image spatial scales, (c) and field/image data linkage strategies. Our results confirm the utility of both ALOS/PALSAR and Landsat data for the provision of accurate estimates of aboveground biomass, with accuracy increasing markedly with increasing spectral resolution, decreasing spatial resolution, and as the spatial mismatches between field and image data sources are minimized.

  13. Teaching science for conceptual change: Toward a proposed taxonomy of diagnostic teaching strategies to gauge students' personal science conceptions

    Science.gov (United States)

    Shope, Richard Edwin, III

    Science instruction aims to ensure that students properly construct scientific knowledge so that each individual may play a role as a science literate citizen or as part of the science workforce (National Research Council, 1996, 2000). Students enter the classroom with a wide range of personal conceptions regarding science phenomena, often at variance with prevailing scientific views (Duschl, Hamilton, & Grandy, 1992; Hewson, 1992). The extensive misconceptions research literature emphasizes the importance of diagnosing students' initial understandings in order to gauge the accuracy and depth of what each student knows prior to instruction and then to use that information to adapt the teaching to address student needs. (Ausubel, 1968; Carey, 2000; Driver et al., 1985; Karplus & Thier, 1967; Mintzes, Wandersee, & Novak, 1998; Osborne & Freyberg, 1985; Project 2061, 1993; Strike & Posner, 1982, 1992; Vygotsky, 1934/1987). To gain such insight, teachers diagnose not only the content of the students' personal conceptions but also the thinking processes that produced them (Strike and Posner, 1992). Indeed, when teachers design opportunities for students to express their understanding, there is strong evidence that such diagnostic assessment also enhances science teaching and learning (Black & William, 1998). The functional knowledge of effective science teaching practice resides in the professional practitioners at the front lines---the science teachers in the classroom. Nevertheless, how teachers actually engage in the practice of diagnosis is not well documented. To help fill this gap, the researcher conducted a study of 16 sixth grade science classrooms in four Los Angeles area middle schools. Diagnostic teaching strategies were observed in action and then followed up by interviews with each teacher. Results showed that teachers use strategies that vary by the complexity of active student involvement, including pretests, strategic questions, interactive discussion, participatory demonstration, active inquiry, and metacognitive dialogue. Each strategy evokes expression of what students know prior to instruction, yielding different levels of useful information. These findings guided the construction of a proposed taxonomy of diagnostic teaching strategies to gauge students' personal science conceptions. This may be useful to guide future research and professional development of science teaching practice.

    Persuasive messages for marketing healthcare services in general and coordinated care in particular are more important now for providers, hospitals, and third-party payers than ever before. The combination of measurement-based information and creativity may be among the most critical factors in reaching markets or expanding markets. The research presented here provides an approach to marketing coordinated care services which allows healthcare managers to plan persuasive messages given the market conditions they face. Using market respondents' thinking about product attributes combined with distance measurement between pairs of product attributes, a conceptual marketing map is presented and applied to advertising, message copy, and delivery. The data reported here are representative of the potential caregivers for which the messages are intended. Results are described with implications for application to coordinated care services. Theory building and marketing practice are discussed in the light of findings and methodology. PMID:19813121

After misconceptions are identified, the pathfinder software fails to provide any feedback on these misconceptions. To overcome this weakness, we have been developing a mobile-based concept mapping tool providing visual, textual and remedial feedback (ex. videos, website links and applets) on the concept relations. This information is then placed on the expert concept map, but not on the students concept map. Additionally, students are asked to note what they understand from given feedback, and given the opportunity to revise their knowledge maps after receiving various types of feedback.

  2. The EU-strategy against soil acidification. Concept of the critical load; Die EU-Strategie gegen Bodenversauerung. Konzept der kritischen Belastung

    1998-10-01

    The development of so-called `novel forest damages` is considered to be - at least partly - a result of the impact of certain air pollutants such as sulphur and nitrogen oxides; these precipitate as acid rain and acidify the soil, thus damaging sensitive ecosystems, e.g. forests. To combat acidification, the EU Commission has produced a Community strategy, which is based on the concept of critical loads. The DGMK report 548 deals with this concept of critical loads and with the measures to combat soil acidifiction. It explains that critical loads are not damage thresholds, but environmental standards, and deviation does not necessarily required any action. It demonstrates, why the reduction of sulphur dioxide emissions, formed during the utilization of fluid fuels, is not a cost-effective measures. It proposes continued implementation of agreed plans for emission reduction, before additional legislative steps are considered. This report contains information to June 1998 inclusive. (orig.) [Deutsch] Die Entstehung der sogenannten `neuartigen Waldschaeden` fuehrt man zum Teil auf die Einwirkung gewisser Luftschadstoffe wie Schwefel- und Stickoxide zurueck, die als saurer Regen auf die Erde niedergehen und zu einer Versauerung des Bodens und damit zu einer Schaedigung empfindlicher Oekosysteme wie der Waelder fuehren koennen. Die EU-Kommission hat eine Strategie der EU zur Bekaempfung dieser Versauerung entwickelt, die auf dem Konzept der kritischen Belastungen beruht. Der DGMK-Bericht 548 setzt sich mit diesem Konzept der kritischen Belastungen sowie mit den Massnahmen zur Bekaempfung der Bodenversauerung auseinander. Er erlaeutert, dass kritische Belastungen keinen Schwellenwert, sondern einen Umweltstandard darstellen, aus dessen Ueberschreitung nicht zwingend ein Handlungsbedarf abgeleitet werden kann. Er erlaeutert ferner, warum vor allem die Reduktion der Schwefeldioxidemissionen, die beim Einsatz fluessiger Kraft- und Brennstoffe entstehen, keine kosteneffektive Massnahme darstellt, und schlaegt vor, zunaechst die bereits beschlossenen Vorhaben zur Emissionsreduktion zu implementieren, bevor weitere gesetzgeberische Schritte unternommen werden.

    2013-11-13

    Domestic water and sanitation provide examples of a situation where long-term, target-driven efforts have been launched with the objective of reducing the proportion of people who are water-insecure, most recently through the millennium development goals (MDGs) framework. Impacts of these efforts have been monitored by an increasingly evidence-based system, and plans for the next period of international policy, which are likely to aim at universal coverage with basic water and sanitation, are being currently developed. As distinct from many other domains to which the concept of water security is applied, domestic or personal water security requires a perspective that incorporates the reciprocal notions of provision and risk, as the current status of domestic water and sanitation security is dominated by deficiency This paper reviews the interaction of science and technology with policies, practice and monitoring, and explores how far domestic water can helpfully fit into the proposed concept of water security, how that is best defined, and how far the human right to water affects the situation. It is considered that they fit well together in terms both of practical planning of targets and indicators and as a conceptual framework to help development. The focus needs to be broad, to extend beyond households, to emphasize maintenance as well as construction and to increase equity of access. International and subnational monitoring need to interact, and monitoring results need to be meaningful to service providers as well as users. PMID:24080628

Nearly 50 years of uranium mining and milling at these facilities have caused radioactive contamination of the environment. This paper is devoted to identification of the main sources of actual and potential releases of radioactive materials to the environment, assessment of the radiological and environment risk as a basis for remedial measures. Choice of the best strategy for site restoration are described in this paper. (author)

  5. Language Management x 3 : A Theory, a Sub-concept, and a Business Strategy Tool

    DEFF Research Database (Denmark)

    Sanden, Guro Refsum

    2014-01-01

    The term ‘language management’ has become a widely used expression in the sociolinguistic literature. Originally introduced by Jernudd and Neustupný in 1987, as a novel continuation of the language planning tradition stemming from the 1960/70s, language management along these lines has developed into the Language Management Theory (LMT). A second definition of language management, diverting from LMT, can be found in the work of Spolsky, who treats language management as a theoretical component of the wider concept of language policy. Furthermore, over the past 15 years a number of scholars, particularly from the international management discipline, appear to have taken an interest in language as a variable in business and corporate management. It is also common to refer to this research field as language management. This conceptual article offers a theoretically based comparison of the three definitions of language management, before discussing five main focus points, which may be used to highlight their analytical differences.

    Full Text Available The personality of a city is an important concept to be created and evaluated by local administrators as this should be part of the touristic strategic approach. The aim of this paper is to create a research instrument that allows researchers to define the brand personality of a Romanian city. In order to use one instrument in a specific geographical area, the instrument has to be created using a qualitative research. Three focus groups were conducted in order to identify items to create the research instrument which is presented at the end of the paper. This research is a preliminary step for a future quantitative research that is intended to measure the city brand personality of the city of Iasi. The created instrument can be applied to any Romanian city.

Thus, 115.4 million people may be living with dementia in 2050. Alzheimer's disease (AD is the leading cause of dementia and is present in 60%–70% of people with dementia. Unfortunately, there are few approved drugs that can alleviate the cognitive or behavioral symptoms of AD dementia. Recent studies have revealed that pathophysiological changes related to AD occur decades before the appearance of clinical symptoms of dementia. This extended preclinical phase of AD provides a critical chance for disease-modifying agents to halt or delay the relentless process of AD. Although several trials targeting various pathological processes are ongoing, the examination of the combined use of different approaches to combat AD seems warranted. In this article, we will review current therapies, future strategies, and ongoing clinical trials for the treatment of AD with a special focus on combination therapies. Furthermore, preventive strategies for cognitively normal subjects in the presymptomatic stages of AD will also be addressed. In this review, we discuss current hypotheses of the disease process. In the decades since the approval of cholinesterase inhibitors, no new drug has ultimately demonstrated clear success in clinical trials. Given the difficulties that have been encountered in attempts to identify a single drug that can treat AD, we must pursue effective multi-target strategies, ie, combination therapies. The combination of cholinesterase inhibitors and memantine is considered well tolerated and safe, and this combination benefits patients with moderate-to-severe AD. In contrast, with the exception of adjuvant therapies of conventional drugs, combinations of different disease-modifying agents with different mechanisms may have promising synergic effects and benefit cognition, behavior, and daily living function. Keywords: disease-modifying agent, combination therapy, Alzheimer's disease

    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.

    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.

  10. Prospects and recommendations for risk mapping to improve strategies for effective malaria vector control interventions in Latin America.

    With malaria control in Latin America firmly established in most countries and a growing number of these countries in the pre-elimination phase, malaria elimination appears feasible. A review of the literature indicates that malaria elimination in this region will be difficult without locally tailored strategies for vector control, which depend on more research on vector ecology, genetics and behavioural responses to environmental changes, such as those caused by land cover alterations, and human population movements. An essential way to bridge the knowledge gap and improve vector control is through risk mapping. Malaria risk maps based on statistical and knowledge-based modelling can elucidate the links between environmental factors and malaria vectors, explain interactions between environmental changes and vector dynamics, and provide a heuristic to demonstrate how the environment shapes malaria transmission. To increase the utility of risk mapping in guiding vector control activities, definitions of malaria risk for mapping purposes must be standardized. The maps must also possess appropriate scale and resolution in order to become essential tools in integrated vector management (IVM), so that planners can target areas in greatest need of control measures. Fully integrating risk mapping into vector control programmes will make interventions more evidence-based, making malaria elimination more attainable. PMID:26694047

    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 as the Indicator System is concerned, it has been decided to prepare a Report on Indicators for the success of adaptation measures and the challenges facing Germany. Proposals regarding indicators for monitoring the success of the adaptation strategy and a proposal for a suitable illustration in the shape of an indicator-based report for adaptation at Federal level are to be presented in spring 2011, in conjunc-tion with the publication of the Action Plan 'Adaptation at Federal Level'. This may be added to the Action Plan either as an enclosure or as a supplementary document. Furthermore it is planned to incorporate the preparation of a Report on Indicators and the underlying Indicator Set as a Measure under the Action Plan. This is to be achieved by 2013. Subsequently, regular reviews of progress made in adapting to the consequences of climate change could be carried out by means of progress reports. The DAS Indicator System and the Adaptation Report will be developed in a multi-stage process on behalf of the BMU. This process will be under the aegis of UBA / KomPass. The Consultation Project entitled 'Indicators for the German Adaptation Strategy' discussed in this document, was initiated in December 2008 and completed in March 2010. It resulted in an initial set of indicators for adaptation at Federal level and a structure for the Report on Indicators. This set of indicators will be consolidated in a R and E project that is scheduled to run (with a time lag) from the beginning of 2010 until the beginning of 2011. One of the objectives of this R and D project is to produce a Report on Indicators. The Consultation Project was initially based on a sectoral and very pragmatic approach thus reflecting the basic structural approach of the DAS. The statements contained in the DAS refer essentially to the Action Fields and to two additional Cross-sectional Fields. The Con-sultation Project dealt with all Action Fields and Cross-sectional Fields. These are: - human health, - building sector, - water regime, water management, coastal and marine pr

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

    International Nuclear Information System (INIS)

    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)

  14. On-Orbit Maintenance Operations Strategy for the International Space Station - Concept and Implementation

    2001-01-01

    The International Space Station (ISS) has an operational mission and profile that makes it a Logistics and Maintenance (L&M) support challenge different from previous programs. It is permanently manned, assembled on orbit, and multi-national. With this technical and operational challenge, a unique approach is needed to support the hardware and crew. The key is the integration of on-orbit and ground analysis, supply, maintenance, and crew training into a coherent functional process that supports ISS goals and objectives. To integrate all the necessary aspects of hardware and personnel to support on-orbit maintenance, a myriad of products and processes must be created and coordinated, such that the right resources are in the right place at the right time to ensure continued ISS functionality. This paper will familiarize the audience with ISS On-Orbit Maintenance (OOM) concepts and capabilities for different maintenance tasks and discuss some of the logic behind their selection. It will also identify the operational maintenance support responsibility split between the U.S. and the various International Partners (IPs).

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

    International Nuclear Information System (INIS)

    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 enlightened citizens, policy-makers and leaders. Author will advocate the inclusion of certain lessons in curriculum whereby child should cultivate rationality of the use of radiation and eliminate fear against radiation. This would enable adolescent brains to permeate the judicious learning leading to the formation of their mindset and related behaviour. The psychological and sociological impact of radiation education with the possible questions in the minds of august audience and luminaries are also intended to be discussed. The logics based upon the adolescent brain and age-related behavioral manifestations will further advocate the proposed strategic and premeditated theory on ethical education on the use of radiation technology.

    Full Text Available This paper aims to investigate strategies of transcultural care emerging from group work in Family Health programs. It is a qualitative study based on Madeleine Leininger’s theory of the diversity and universality of care. Subjects were health professionals participating in Family Health teams, all of whom were group coordinators for diabetics and hypertensive patients in basic health care units within a sanitary district of Belo Horizonte. Participative observation and open interviews were used for data collection. Information was collected between June and November 2006, respecting ethical issues. Data interpretation was based on Bardin’s proposal for content analysis. The themes we found were as follows: the group in a transcultural perspective, how the group is structured, work strategies with diabetic and hypertensive groups, the technology of work with groups in a transcultural perspective, and the challenges and advances of group work in Family Health programs. Results indicate that group work is still poorly innovative, with a need to increase multidisciplinarity; current methodologies emphasize a culture of disease and recurrent pedagogic processes such as approaches still focused on the transmission of knowledge. It is worth noting that certain professionals, such as nurses, physical therapists and social workers, practice a differentiated approach centered on the culture of subjects and on the validation of their experiences. The gaze on diabetic and hypertensive patients goes beyond surveillance for medication use, reaching out to those aspects that influence the treatment and control of the disease, within the context in which such patients live. In practice, we were able to recognize and confirm the technical and theoretical difficulties that professionals face when coordinating groups, and to check the belief that resources and logistical support make it possible for groups to become more interesting and effective. Groups were started after these professionals joined the Family Health program, and became a tool to deal with the demands of diabetic and hypertensive patients, becoming an indispensable tool for the daily work of health teams. With its modus operandi the method needs to be recognized, having become a reality in all of the Basic Health Units where, generally speaking, group work is well developed. Group work raises the possibility of transforming teamwork to reach a more horizontal relation between participating agents, meaning that professional power/autonomy needs to be negotiated and subdivided so that knowledge and decisions become shared.

  18. Concepts and Strategies for Transparency Monitoring of Nuclear Materials at the Back End of the Fuel/Weapons Cycle

    International Nuclear Information System (INIS)

    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

    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.

  20. 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.

  1. Discontinuous PWM Modulation Strategy with Circuit-Level Decoupling Concept of Three-Level Neutral-Point Clamped (NPC) Inverter

    DEFF Research Database (Denmark)

    Zhang, Zhe; Thomsen, Ole Cornelius

    2013-01-01

    A new pulse width modulation (PWM) strategy which is an alternative approach of discontinuous PWM (DPWM) for a three-level neutral point clamped (NPC) inverter is developed and presented in this paper. The proposed PWM scheme not only takes advantage of the special properties available in NPC inverters, but also reduces the switching loss of the inverter along with an inherent neutral point (NP) voltage control. Based on a circuit-level decoupling concept, the NPC inverter can be decoupled into two three-level Buck converters in every defined operating section, and thereby the controller design can be simplified. The salient features of the proposed scheme, as compared with the existing carrier-based DPWM strategies, are: 1) its reduced computational processing time, 2) its capability to balance the DC-link voltage without any additional control and 3) its reduced complexity e.g. only one carrier wave needed for pulse width modulating. Same as a space vector modulation, the maximum modulation index, 1.1547, can be attainable by the proposed scheme. Moreover, compared to conventional continuous sinusoidal pulse width modulation, using this technique here the switching losses of the devices can be reduced by one third. In order to explain the operation of this topology properly, the decoupling principle including the driving signal synthesis and the NP potential variation are analyzed in detail in this paper. Finally the viability and performance of the proposed modulation scheme are shown through simulation and experimental results in a laboratory prototype.

    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.

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

    International Nuclear Information System (INIS)

    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

    Learning outcomes are typically developed using standard group-based consensus methods. Two main constraints with standard techniques such as the Delphi method or expert working group processes are: (1) the ability to generate a comprehensive set of outcomes and (2) the capacity to reach agreement on them. We describe the first application of Group Concept Mapping (GCM) to the development of learning outcomes for an interdisciplinary module in medicine and engineering. The biomedical design module facilitates undergraduate participation in clinician-mentored team-based projects that prepare students for a multidisciplinary work environment. GCM attempts to mitigate the weaknesses of other consensus methods by excluding pre-determined classification schemes and inter-coder discussion, and by requiring just one round of data structuring. Academic members from medicine and engineering schools at three EU higher education institutions participated in this study. Data analysis, which included multidimensional scaling and hierarchical cluster analysis, identified two main categories of outcomes: technical skills (new advancement in design process with special attention to users, commercialization and standardization) and transversal skills such as working effectively in teams and creative problem solving. The study emphasizes the need to address the highest order of learning taxonomy (analysis, synthesis, problem solving, creativity) when defining learning outcomes. PMID:24323801

    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. Mapping the inhomogeneity of the U and Th distributions using sample size concept in the field conditions

    International Nuclear Information System (INIS)

    Indigenously fabricated portable gamma-ray spectrometer (PGRS) is used for the measurement of gamma activity of 214Bi (1.76 MeV) and 208Tl (2.62 MeV), under field conditions in Mohar area, Shivpuri Distt. (MP). The energies are discriminated by using a NaI (Tl) crystal of size 1.75 inch x 2 inch. PGRS used to map the primordial elemental distributions shows reversals of concentration of thorium and uranium (represented by radium group) in field and lab analysis in many samples, which is attributed to the inhomogeneity of distribution of these elements in the area. The concept of difference in the volume of dish shaped field sample and the randomly picked up sample from the field grid point (400 gm in lab analysis) is utilized to interpret the inhomogeneity of these elements. However interpretations are based on the assumption that these primordial elements (U, Th) are in secular equilibrium and the terrain has low topographic relief. (author)

    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 stations.

    This paper outlines a method for solving the stereovision matching problem using edge segments as the primitives. In stereovision matching the following constraints are commonly used: epipolar, similarity, smoothness, ordering and uniqueness. We propose a new matching strategy under a fuzzy context in which such constraints are mapped. The fuzzy context integrates both Fuzzy Clustering and Fuzzy Cognitive Maps. With such purpose a network of concepts (nodes) is designed, each concept represen...

    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...

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

    International Nuclear Information System (INIS)

    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 interviewed. The results indicate, in accordance with other research results, that rationalisations and changes must be combined with work development and the participation of the employees to be successful. Outsourcing has been used for some activities. All the companies have established a joint maintenance department for their units. The companies have been moving towards lean organization which has increased the work load of the staff. Therefore more planning is required to get a optimal resource allocation, to avoid problems at work peaks. All the plants have abandoned a downright customer-supplier relation for the benefit of one competent maintenance supplier with a comprehensive view. As a result the contractual undertaking of the maintenance department towards the production units is made on a long term basis. The new maintenance strategy is based on status controls for condition based maintenance and on riskbased analysing methods. There are modern computer-based maintenance systems at all the plants. Computer-based instruments are used direct in the production line where they require a competence shift in the staff. Positive effects that appeared in the interviews are better possibilities for experience feed back and methods development, access to a wider and larger competence and a joint working method. The results show that there are already some positive effects and there are more to be expected. But it is also clear that these effects have neither come as easily nor as fast as was expected. Possible negative effects: there is a risk that the staffing might be too scarce, especially in work peaks, e.g. unexpected shutdowns. A high work load and much overtime work mean greater strain on the staff. Problems with job satisfaction and motivation, chiefly after the change to a matrix organisation. Uncertainties as to responsibility and roles in the new organisation. The practical competence might 'disappear' in the present competence shift focusing on analytical, computer based methods. The difficulties of risk based methods are several: they might not cor

    Ledger, Antoinette Frances

    This study sought to examine whether collaborative concept mapping would affect the achievement, science self-efficacy and attitude toward science of female eighth grade science students. The research questions are: (1) Will the use of collaborative concept mapping affect the achievement of female students in science? (2) Will the use of collaborative concept mapping affect the science self-efficacy of female students? (3) Will the use of collaborative concept mapping affect the attitudes of females toward science? The study was quasi-experimental and utilized a pretest-posttest design for both experimental and control groups. Eighth grade female and male students from three schools in a large northeastern school district participated in this study. The achievement test consisted of 10 multiple choice and two open-response questions and used questions from state-wide and national assessments as well as teacher-constructed items. A 29 item Likert type instrument (McMillan, 1992) was administered to measure science self-efficacy and attitude toward science. The study was of 12 weeks duration. During the study, experimental group students were asked to perform collaborative concept map construction in single sex dyads using specific terms designated by the classroom teacher and the researcher. During classroom visitations, student perceptions of collaborative concept mapping were collected and were used to provide insight into the results of the quantitative data analysis. Data from the pre and posttest instruments were analyzed for both experimental and control groups using t-tests. Additionally, the three teachers were interviewed and their perceptions of the study were also used to gain insight into the results of the study. The analysis of data showed that experimental group females showed significantly higher gains in achievement than control group females. An additional analysis of data showed experimental group males showed significantly greater gains in achievement than experimental group females. The analysis of science self-efficacy data showed that neither experimental nor control group females increased their scores pre to posttest, both showed small decreases in scores. However, the posttest scores of the experimental group females were significantly higher than the posttest scores of the control group females. The analysis of the attitude toward science survey data showed that the scores of the experimental group females did not change from pre to posttest. However, scores of the control group females declined from pre to posttest. (Abstract shortened by UMI.)

Três ADs geradas a partir de oito covariáveis preditoras, ligadas aos fatores relevo e organismos, amostradas nos polígonos originais de um mapa de solos e em polígonos deslocados em 100 e 160 m para o seu interior, foram utilizadas para predizer classes de solos. O modelo de AD a partir de observações distantes 160 m da borda dos polígonos no mapa original é menos complexo e tem melhor desempenho preditivo. Abstract in english 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 mappi [...] ng (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.

    Full Text Available Abstract Background Terminologies and classifications are used for different purposes and have different structures and content. Linking or mapping terminologies and classifications has been pointed out as a possible way to achieve various aims as well as to attain additional advantages in describing and documenting health care data. The objectives of this study were: • to explore and develop rules to be used in a mapping process • to evaluate intercoder reliability and the assessed degree of concordance when the 'Swedish primary health care version of the International Classification of Diseases version 10' (ICD-10 is matched to the Systematized Nomenclature of Medicine, Clinical Terms (SNOMED CT • to describe characteristics in the coding systems that are related to obstacles to high quality mapping. Methods Mapping (interpretation, matching, assessment and rule development was done by two coders. The Swedish primary health care version of ICD-10 with 972 codes was randomly divided into an allotment of three sets of categories, used in three mapping sequences, A, B and C. Mapping was done independently by the coders and new rules were developed between the sequences. Intercoder reliability was measured by comparing the results after each set. The extent of matching was assessed as either 'partly' or 'completely concordant' Results General principles for mapping were outlined before the first sequence, A. New mapping rules had significant impact on the results between sequences A - B (p Conclusion Mapping from ICD-10-categories to SNOMED CT needs clear and extensive rules. It is possible to reach high intercoder reliability in mapping from ICD-10-categories to SNOMED CT. However, several obstacles to high quality mapping remain due to structure and content characteristics in both coding systems.

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 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.

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

    Directory of Open Access Journals (Sweden)

    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.

The students were intentiona [...] lly provoked to merge concepts from chemistry and biology, in order to better understand and explain the biological consequences of isomerism. The concept maps produced by the students before and after the activities confirmed the appearance of relationships among chemical and biological concepts, which were qualitatively evaluated. This work shows that concept maps can be used to follow the students' progress towards interdisciplinarity, and to help the teacher to devise future classroom activities to reinforce and to expand interdisciplinary relationships.

    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.

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

    International Nuclear Information System (INIS)

    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.

    This article describes the use of concept mapping to develop a pictorial multivariate conceptual framework of staff views of a program of supported employment (SE) for individuals with severe mental illness. The SE program involves extended individualized supported employment for clients through a mobile job support worker (MJSW) who maintains contact with the client after job placement and supports the client in various ways. All 14 staff members of a psychiatric rehabilitation agency with assignments associated with the SE program. They brainstormed a large number of specific program activity statements (N = 96), sorted and rated the statements, and interpreted the map that was produced through multidimensional scaling and hierarchical cluster analysis. The resulting map enabled identification of 4 issues that should be included in any theory of SE programs--the specific activity sequences that characterize the program itself; the pattern of local program evolution; the definition of program staff roles; and the influence of key contextual factors such as the client's family or the program's administrative structure. The implications of concept mapping methodology for theory development and program evaluation are considered. PMID:7962880

    Nursing students are exposed to a vast amount of information and reading material that is very specific, technical, and new to the students. Unless nurse educators provide a learning environment that promotes understanding through interaction, students might only commit unassimilated information to their short-term memory through rote learning, and no meaningful learning will occur. Nursing students must be able to link learned facts, concepts and principles with new knowledge in order to make sound rational decisions in practice (All & Havens 1997:1210, 1213. The aim of this paper is to describe the utilisation of concept-mapping as a teaching method to facilitate critical thinking by students in nursing education. The description of the utilisation of concept-mapping is done from the theoretical framework of concept-mapping and critical thinking to provide the epistemological basis for concept-mapping (Facione 1990:6, 13. Based on the exploration and description of the theoretical frameworks, four steps to facilitate critical thinking were formulated through concept-mapping on the basis of the educational process: the identification, interactive constructing process, formulation and evaluation steps. It is concluded that the utilisation of these steps will assist nurse educators to implement conceptmapping as a teaching method to facilitate critical thinking by student nurses in nursing education. Recommendations are made.

    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...

    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.

    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.

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

    International Nuclear Information System (INIS)

    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 HTGR fuel cycle and the possibility of achieving high fuel burnups in the HTGR core under conditions of safe reactor operation are the key conditions that make the pebble bed HTGR concept attractive as the basis for long-term energy development. They are also the major reasons why this concept has been chosen for the current studies. Efficient utilization of different forms and types of fuels is possible even in the same core. Uranium, plutonium, and mixed fuels in dicarbide and dioxide forms are studied as possible elements of fuel composition to be utilized as a long-term energy source. To improve the pebble bed HTGR behavior at elevated temperatures, refractory and chemically stable ZrC has been considered as an alternative to SiC. The current studies of the pebble bed HTGR concept are performed with SCALE 4.3 and MCNP 4A. SCALE 4.3 is a multipurpose computer code system that has modules for deterministic criticality and burnup calculations. Application of this code system allows accurate modeling of fuel depletion. As a result, fuel lifetime is evaluated for a particular combination of materials utilized. MCNP 4A is the code system for Monte Carlo modeling. The Monte Carlo method offers the possibility of taking into account all the details of the three-dimensional geometry of the real pebble bed core. The model of the pebble bed HTGR core takes into account the well-known double heterogeneity due to utilization of fuel pebbles and dispersion fuel. The methodology of realistic modeling for detailed descriptions of the pebble bed HTGR core developed earlier is applied to provide sufficient accuracy in both the Monte Carlo and deterministic calculations. Accuracy of all the models used in the deterministic calculations with SCALE is validated using the results of the MCNP calculations with the detailed three-dimensional model. The current analysis of the long-term energy source based on the pebble bed HTGR concept is aimed toward an inherent balance between the fuel material depletion and material conversion mentioned earlier. The studies concentrate on the pebb

  10. Manifold dynamics in the Earth-Moon system via isomorphic mapping with application to spacecraft end-of-life strategies

    2014-12-01

    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 application of manifold dynamics to defining suitable, convenient end-of-life strategies for spacecraft orbiting the Earth. Seven distinct options are identified, and lead to placing the spacecraft into the final disposal orbit, which is either (a) a lunar capture orbit, (b) a lunar impact trajectory, (c) a stable lunar periodic orbit, or (d) an outer orbit, never approaching the Earth or the Moon. Two remarkable properties that relate the velocity variations with the spacecraft energy are employed for the purpose of identifying the optimal locations, magnitudes, and directions of the velocity impulses needed to perform the seven transfer trajectories. The overall performance of each end-of-life strategy is evaluated in terms of time of flight and propellant budget.

    Because of changes in the medical environment, nurses must maintain the ability of divergent thinking to solve the health problems of patients. However, many nurses whose work in clinical practice has become routine have lost the ability of creativity. To cultivate nurses creativity should be a goal of nursing education. The purpose of this study is to evaluate a nursing concepts teaching protocol by utilizing teaching strategies directed toward creativity to promote creativity in two-year RN-BSN students. This study design is a time series and one group experiment utilizing multiple instances of treatment. Teaching strategies for creativity were applied to a teaching unit and 52 two-year RN-BSN students were tested for creativity before the end of each semester. This study was conducted from March, 1999 to May, 2000, but only 30 students completed all tests and reached a 58% return rate. Torrance s (1974) definitions of creativity includ fluency, flexibility, and uniqueness were followed and the instrument, a questionnaire on Creativity in the application of the Nursing Process Tool (CNPT), was designed based on Emerson (1988). The content validity of Chinese-version CNPT was.79. The inter-coder reliability between two researchers was.84 following a coding guide that ten nursing education experts had established. The results indicated that 30 two-year RN-BSN students had improved fluency and flexibility. The improvements reached a significant level after the third semester. Only uniqueness declined. It is suggested that nursing faculty apply teaching strategies uniqueness more often in a teaching protocol of nursing concepts. By utilizing teaching strategies of creativity in a teaching protocol of nursing concepts, it is expected that two-year RN-BSN students can acquire characteristics of creativity for problem-solving skills in clinical settings.

    Full Text Available Abstract Background Schistosomiasis and soil-transmitted helminthiasis (STH are endemic in Sierra Leone confirmed by national mapping in 2008. To better inform planning of preventive chemotherapy strategy, another survey was conducted before mass drug administration (MDA in seven districts according to the mapping results or local knowledge. Fifty-nine chiefdoms and one school in every chiefdom were selected. Thirty school children aged 9-14 years from each school (total: 1760 were examined by parasitological methods for infection with Schistosoma mansoni and STHs. Results The overall prevalence of S. mansoni was 40.2% (95% confidence interval (CI: 37.9-42.5%, particularly in Kailahun (63.3%, Kenema (46.7%, Koinadugu (41.9% and Kono (71.7%. The results demonstrated the focal distribution of S. mansoni in Bo, Tonkolili and Bombali districts with prevalence ranging from 0.0-63.3%, 3.3-90.0% and 0.0-67.9% respectively. The arithmetic mean intensity of S. mansoni infection was 95.4 epg (95% CI: 61.4-129.5 epg, Heavy mean intensity of infection was found in Kailahun (120.2 epg, Kenema (104.5 epg, Koinadugu (112.3 epg and Kono (250.3 epg. Heavy or moderate infection with S. mansoni occurred in 20.7% of children examined. Hookworm prevalence was moderate: 31.2% (95% CI: 29.1-33.4%, but high in Bo (50.0% and Tonkolili (56.7%. Hookworm intensity of infection was light with a mean epg of 53.0 (95% CI: 38.4-67.7 epg. Prevalence and intensity of Ascaris lumbricoides (1.5%, 17.8 epg and Trichuris trichiura (2.5%, 20.3 epg was low. Conclusions The prediction by previous spatial analysis that S. mansoni was highly endemic across north-eastern Sierra Leone was confirmed with a significant proportion of children heavily or moderately infected. The distribution of S. mansoni in Bo, Tonkolili and Bombali districts ranged widely, highlighting the importance of considering the nature of focal transmission in national mapping exercises. These results were used to refine the MDA for schistosomiasis control to chiefdom implementation units rather than the entire district in these 3 districts. The survey demonstrated that sufficient number of survey sites for schistosomiasis mapping in each district should be used to provide a better national planning of MDA activities, and that it is affordable with the contributions from all parties involved and national resources mobilized.

  15. The effects of using concept mapping as an artifact to engender metacognitive thinking in first-year medical students' problem-based learning discussions: A mixed-methods investigation

    Shoop, Glenda Hostetter

    Attention in medical education is turning toward instruction that not only focuses on knowledge acquisition, but on developing the medical students' clinical problem-solving skills, and their ability to critically think through complex diseases. Metacognition is regarded as an important consideration in how we teach medical students these higher-order, critical thinking skills. This study used a mixed-methods research design to investigate if concept mapping as an artifact may engender metacognitive thinking in the medical student population. Specifically the purpose of the study is twofold: (1) to determine if concept mapping, functioning as an artifact during problem-based learning, improves learning as measured by scores on test questions; and (2) to explore if the process of concept mapping alters the problem-based learning intragroup discussion in ways that show medical students are engaged in metacognitive thinking. The results showed that students in the problem-based learning concept-mapping groups used more metacognitive thinking patterns than those in the problem-based learning discussion-only group, particularly in the monitoring component. These groups also engaged in a higher level of cognitive thinking associated with reasoning through mechanisms-of-action and breaking down complex biochemical and physiologic principals. The students disclosed in focus-group interviews that concept mapping was beneficial to help them understand how discrete pieces of information fit together in a bigger structure of knowledge. They also stated that concept mapping gave them some time to think through these concepts in a larger conceptual framework. There was no significant difference in the exam-question scores between the problem-based learning concept-mapping groups and the problem-based learning discussion-only group.

  19. A Fast-Processing Modulation Strategy for Three-Phase Four-Leg Neutral-Point-Clamped Inverter Based on the Circuit-Level Decoupling Concept

    DEFF Research Database (Denmark)

    Ghoreishy, Hoda; Zhang, Zhe

    2012-01-01

    In this paper, a modulation strategy based on the circuit-level decoupling concept is proposed and investigated for the three-level four-leg neutral-point-clamped (NPC) inverter,with the aim of delivering power to all sorts of loads, linear/nonlinear and balanced/unbalanced. By applying the proposed modulation strategy, the four-leg NPC inverter can be decoupled into three three-level Buck converters in each defined operating section. This makes the controller design much simpler compared to the conventional four-leg NPC inverter controllers. Also, this technique can be implemented with a simple logic and can be processed very quickly. Moreover, the switching loss is reduced substantially and the dc-link capacitors’ voltages balance is also achieved without any feedback control. The proposed modulation technique is verified by the experiment.

  20. The reading room: Exploring the use of literature as a strategy for integrating threshold concepts into nursing curricula.

    McAllister, Margaret; Lasater, Kathie; Stone, Teresa Elizabeth; Levett-Jones, Tracy

    2015-11-01

    In addition to acquiring a solid foundation of clinical knowledge and skills, nursing students making the transition from lay person to health professional must adopt new conceptual understandings and values, while at the same time reflecting on and relinquishing ill-fitting attitudes and biases. This paper presents creative teaching ideas that utilise published narratives and explores the place of these narratives in teaching threshold concepts to nursing students. Appreciating nuance, symbolism and deeper layers of meaning in a well-drawn story can promote emotional engagement and cause learners to care deeply about an issue. Moreover, aesthetic learning, through the use of novels, memoirs and picture books, invites learners to enter into imagined worlds and can stimulate creative and critical thinking. This approach can also be a vehicle for transformative learning and for enhancing students' understanding and internalisation of threshold concepts that are integral to nursing. Guided engagement with the story by an effective educator can help learners to examine taken-for-granted assumptions, differentiate personal from professional values, remember the link between the story and the threshold concept and re-examine their own perspectives; this can result in transformative learning. In this paper, we show how threshold concepts can be introduced and discussed with nursing students via guided engagement with specific literature, so as to prompt meaningful internalised learning.

The focus of this paper is to assess crucial [...] attributes in consumer purchase decision and how companies are organizing themselves to serve this population segment. It examines the case of the consumption of an electrical appliance - tanquinho (a less sophisticated washing machine) by low-income population. Thus, a field research was conducted in retail stores with low-income consumers in the city of São Paulo, in the last quarter of 2005. Primary data obtained were subjected to analysis using statistical techniques. The results show that to serve popular markets is not simply a matter of adopting low-cost generic strategies. There is also a need of an adequacy strategy, a fit strategy, which configures the balance between the search for the best price bid responses and addressing the needs of low-income consumers.

  3. Lymphatic mapping to tailor selective lymphadenectomy in cN0 tongue carcinoma: beyond the sentinel node concept

    International Nuclear Information System (INIS)

    Cervical lymph node status is the most important pathological determinant of prognosis and decision making in head and neck squamous cell carcinoma (SCC). The aim of this study was to demonstrate that lymphoscintigraphy (LS) can supply a complete map of the lymphatic drainage before surgery, allowing planning of the type of intervention and serving to guide lymphadenectomy. The study population comprised 14 patients with T2-4 SCCs of the tongue and clinically negative lymph nodes in the neck (cN0) who were scheduled to undergo tumour resection and selective level I-IV neck dissection extended to level V. LS was performed in all patients following the injection of 99mTc-colloidal sulphide in three aliquots around the primary lesion. Dynamic, static and tomographic images of the head and neck were acquired. The operative specimens were subjected to lymphoscintigraphic evaluation. Preoperative and postoperative imaging results were compared with the pathological findings. All nodes were examined using haematoxylin-eosin staining. Preoperative LS was successful in all patients. Preferential pathways of lymphatic drainage were identified: level II of the neck was the most common lymphatic drainage pattern, followed by levels IV and III. Contralateral drainage occurred in 11 patients and in two of them metastatic nodes were found on the contralateral side. Metastases were observed only in radioactive lymph nodes. LS is able to supply a complete map of the lymphatic drainage before surgery, making it possible to tailor selective neck dissection to each individual patient based on the results of preoperative mapping, thereby sparing healthy lymphatic tissue and reducing surgery-related morbidity.

    The Fox-Wolf River basin in east-central Wisconsin was selected to test concepts for a water-resources information system using digital mapping technology. This basin of 16,800 sq km is typical of many areas in the country. Fifty digital data sets were included in the Fox-Wolf information system. Many data sets were digitized from 1:500,000 scale maps and overlays. Some thematic data were acquired from WATSTORE and other digital data files. All data were geometrically transformed into a Lambert Conformal Conic map projection and converted to a raster format with a 1-km resolution. The result of this preliminary processing was a group of spatially registered, digital data sets in map form. Parameter evaluation, areal stratification, data merging, and data integration were used to achieve the processing objectives and to obtain analysis results for the Fox-Wolf basin. Parameter evaluation includes the visual interpretation of single data sets and digital processing to obtain new derived data sets. In the areal stratification stage, masks were used to extract from one data set all features that are within a selected area on another data set. Most processing results were obtained by data merging. Merging is the combination of two or more data sets into a composite product, in which the contribution of each original data set is apparent and can be extracted from the composite. One processing result was also obtained by data integration. Integration is the combination of two or more data sets into a single new product, from which the original data cannot be separated or calculated. (USGS)

  6. STRATEGIC MAPS AND CRITICAL FACTORS FOR PROJECT MANAGEMENT MATURITY: A PROPOSAL

    2010-06-01

    Full Text Available Project Management (PM and Strategic Management (SM are two subjects of growing importance in the corporate environment which are normally considered in isolation. One way of integrating these two concepts might be via the concept of project management maturity (Westphal et al., 2008. Rabechini and Pessoa (2005 state that to obtain project management maturity, it is necessary to achieve success in a number of critical factors which include organizational culture and structure, as well as sponsorship at both tactical and strategic levels (Silva et al., 2008. Another way of achieving this connection is by using Balanced Scorecard (BSC as an auxiliary tool to integrate between projects and organizational strategy (Brock et al., 2003. The original developers of the BSC, Kaplan e Norton, subsequently developed the concept of strategy mapping, which they affirm "represents the missing link between the formulation and the execution of the strategy" (Kaplan e Norton, 2004. This paper proposes a strategy map identifying critical factors for attaining project management maturity. To formulate the map, we used a qualitative, exploratory approach oriented by Project Management theory and strategy mapping. We first identified 13 critical factors, then developed a strategy map, which was evaluated by six specialists (three in SM area and three in PM area.The results suggest links between strategic mapping nad critical factors in project management. It also contributes to both areas independently. Specifically, the study identifies critical factors for project management maturity while demonstrating the applicability of strategic mapping techniques to Balanced Scorecard concepts.

    CERN Document Server

    2010-01-01

    The development of discursive knowledge presumes the communication of meaning as analytically different from the communication of information. Knowledge can then be considered as a meaning which makes a difference. Whereas the communication of information is studied in the information sciences and scientometrics, the communication of meaning has been central to Luhmannâ??s attempts to make the theory of autopoiesis relevant for sociology. Analytical techniques such as semantic maps and the simulation of anticipatory systems enable us to operationalize the distinctions which Luhmann proposed as relevant to the elaboration of Husserlâ??s â??horizons of meaningâ? in empirical research: interactions among communications, the organization of meaning in instantiations, and the self-organization of interhuman communication in terms of symbolically generalized media such as truth, love, and power. Horizons of meaning, however, remain uncertain orders of expectations, and one should caution against reific...

  9. Learners' strategies for reconstructing cognitive frameworks and navigating conceptual change from prior conception to consensual genetics knowledge

    Parrott, Annette M.

    Problem. Science teachers are charged with preparing students to become scientifically literate individuals. Teachers are given curriculum that specifies the knowledge that students should come away with; however, they are not necessarily aware of the knowledge with which the student arrives or how best to help them navigate between the two knowledge states. Educators must be aware, not only of where their students are conceptually, but how their students move from their prior knowledge and naive theories, to scientifically acceptable theories. The understanding of how students navigate this course has the potential to revolutionize educational practices. Methods. This study explored how five 9th grade biology students reconstructed their cognitive frameworks and navigated conceptual change from prior conception to consensual genetics knowledge. The research questions investigated were: (1) how do students in the process of changing their naive science theories to accepted science theories describe their journey from prior knowledge to current conception, and (2) what are the methods that students utilize to bridge the gap between alternate and consensual science conceptions to effect conceptual change. Qualitative and quantitative methods were employed to gather and analyze the data. In depth, semi-structured interviews formed the primary data for probing the context and details of students' conceptual change experience. Primary interview data was coded by thematic analysis. Results and discussion. This study revealed information about students' perceived roles in learning, the role of articulation in the conceptual change process, and ways in which a community of learners aids conceptual change. It was ascertained that students see their role in learning primarily as repeating information until they could add that information to their knowledge. Students are more likely to consider challenges to their conceptual frameworks and be more motivated to become active participants in constructing their knowledge when they are working collaboratively with peers instead of receiving instruction from their teacher. Articulation was found to be instrumental in aiding learners in identifying their alternate conceptions as well as in revisiting, investigating and reconstructing their conceptual frameworks. Based on the assumptions generated, suggestions were offered to inform pedagogical practice in support of the conceptual change process.

    Counter-current chromatography (CCC) is an efficient liquid-liquid chromatography technique for separation and purification of complex mixtures like natural products extracts and synthetic chemicals. However, CCC is still a challenging process requiring some special technical knowledge especially in the selection of appropriated solvent systems. In this work, we introduced a new 9 × 9 map-based solvent selection strategy for CCC isolation of targets, which permit more than 60 hexane-ethyl acetate-methanol-water (HEMWat) solvent systems as the start candidates for the selection of solvent systems. Among these solvent systems, there are clear linear correlations between partition coefficient (K) and the system numbers. Thus, an appropriate CCC solvent system (i.e., sweet spot for K = 1) may be hit by measurement of k values of the target only in two random solvent systems. Besides this, surprisingly, we found that through two sweet spots, we could get a line ("Sweet line") where there are infinite sweet solvent systems being suitable for CCC separation. In these sweet solvent systems, the target has the same partition coefficient (K) but different solubilities. Thus, the better sweet solvent system with higher sample solubility can be obtained for high capacity CCC preparation. Furthermore, we found that there is a zone ("Sweet zone") where all solvent systems have their own sweet partition coefficients values for the target in range of 0.4 honokiol and magnolol from the extracts of Magnolia officinalis Rehd. Et Wils and tanshinone IIA from Salvia miltiorrhiza Bunge. In practice, it is much easier to get a suitable solvent system only by making a simple screening two to four HEMWat two-phase solvent systems to obtain the sweet line or sweet zone without special knowledge or comprehensive standards as references. This is an important advancement for solvent system selection and also will be very useful for isolation of current natural products including Traditional Chinese Medicines. PMID:25980692

Cmaps (n = 69) about climate change are the first set of empirical data that confirms the potential of NeAn. Dispersion was selected as CC in order to check whether students can relate this physical phenomenon with the global perspective of climate change. The patterns found from the NeAn suggest that, despite being exposed to the same didactic activities, some students could not use the CC properly. This may be explained from David Ausubel's learning theory, which stresses the critical role of prior knowledge in the assimilation process of new information.

    In fall 2005, a new initiative was added to the Centers for Ocean Sciences Education Excellence (COSEE) Network. COSEE-Ocean Systems (OS) is a collaborative effort among the University of Maine (UMaine), University of New Hampshire, and Bigelow Laboratory for Ocean Sciences. Being thematic in nature, COSEE-OS has the flexibility to tackle topics that are important on the national scale, such as those highlighted in the recent "Ocean Literacy" campaign. COSEE-OS has the long-term goal of helping COSEE reach rural and inland audiences. We are creating and evaluating a series of interconnected tools and techniques to broaden understanding of oceans in the context of the earth and solar systems. This includes: - Building and training scientist-educator teams who work together to distinguish meaningful "key messages" and the K-12 audiences who would benefit most from exposure to these concepts; - Translating the concepts into innovative products, workshops, and courses that showcase oceans in the Earth-Sun system; - Working with NASA multimedia experts, developing immersive web-based interfaces that will be utilized by and / or customized for other COSEEs; and - Training in-service and pre-service teachers in using ocean phenomena as a vehicle to teach physical concepts using hands-on activities and inquiry based learning. Part of the COSEE-OS strategy is engaging teams with an educational tool called "concept mapping." Dr. Joseph Novak developed concept mapping in the 1960s as a technique for representing knowledge in graphical formats. Used as a group activity this allows COSEE-OS to gather vital information from scientists to construct multimedia products. Another benefit of this activity is helping scientists and educators test the utility of concept mapping for their instructional purposes. To complement the development of concept maps and associated multimedia, a UMaine COSEE-OS pilot workshop was held in July 2006. The workshop targeted middle- and high-school teachers and focused physical concepts that are already an integral part of the pre-college physics, chemistry, physical science, or earth sciences curricula, emphasizing their links to ocean science (e.g., density, pressure, waves). Special efforts were made to developing readily reproducible "hands on" activities and inquiry based learning. Evaluations conducted before, during, and after the workshop reveal that regardless of experience (i.e., "veteran" vs. "new" teacher), location (i.e., coastal vs. inland), or grade level, ocean science is viewed as an attractive medium through which other standards-required topics can be taught. Based on "lessons learned" from the summer workshop, a UMaine semester course is under development for pre-service educators and Marine Sciences majors who may consider entering the field of education.

    Full Text Available O presente trabalho tem como objetivo propor uma nova forma de utilizar os mapas conceituais (MCs) para verificar como os alunos articulam os diferentes materiais instrucionais (MIs) indicados para estudo pelo professor. Isso expande a possibilidade de uso dos MCs como ferramenta de avaliação, norma [...] lmente restrita à aprendizagem dos alunos. O procedimento proposto requer que os alunos incluam informações sobre a origem de cada um dos conceitos do MC, em função dos MIs indicados para estudo. MCs (n = 88) sobre astronomia formam o primeiro conjunto de dados empíricos que ratifica o potencial dessa nova abordagem. Os resultados revelam que houve diferença significativa entre as frequências das proposições que envolvem conceitos com origem no mesmo MI (25%) e as proposições que envolvem conceitos com origem em MIs diferentes (75%). A integração entre diferentes MIs é desejável porque indica uma compreensão histórica mais precisa da evolução da astronomia, bem como os impactos que as descobertas sobre o universo tiveram sobre a sociedade. A análise da relação entre os MIs não exclui a necessidade do professor ler e corrigir os erros conceituais expressos nas proposições elaboradas pelos alunos. Pelo contrário, a nossa proposta se soma aos procedimentos já tradicionais de leitura e avaliação dos MCs para fins de avaliação da aprendizagem. Uma vantagem associada ao procedimento proposto é a possibilidade do professor também avaliar o seu plano de ensino, verificando como os alunos articularam os MIs. Abstract in english This paper aims to propose a new way of using concept maps (Cmaps) to see how students articulate different instructional materials (IMs) selected by the teacher. This expands the possibility of using Cmaps as an assessment tool, usually restricted to students' learning. The proposed procedure asks [...] students for including information about the origin of each of Cmap's concepts, based on the IMs selected for study. Cmaps (n = 88) about astronomy form the first set of empirical data that confirms the potential of this new approach. The results reveal a significant difference between the frequencies of propositions involving concepts from the same IM (25%) and propositions involving concepts from different IMs (75%). The integration between different IMs is valuable because it shows a more accurate understanding of the historical development of astronomy, as well as the impact that the discoveries about the universe had on society. The analysis of the relationship between IMs does not eliminate the necessity of the teacher to check and correct the misconceptions expressed in propositions made by students. Rather, our proposal adds to the traditional procedures for reading and evaluating the Cmaps for assessment purposes of learning. An advantage associated with the proposed procedure is the possibility of the teacher to evaluate your teaching plan, checking how students articulated the IMs.

La temática elegida para su aplicación es la Fusariosis de la espiga de trigo (FET), enfermedad producida por un hongo que afect [...] a al cultivo y cuya aparición se produce ante determinadas condiciones ambientales. El mapa conceptual de la FET fue elaborado usando los conceptos extraídos de los textos utilizados en los diferentes cursos y usando el programa CmapTools. El mapa finalmente fue exportado a formato de página Web, para que todos los estudiantes accedan fácilmente a él desde su propia computadora. Se concluye que al utilizar el mapa conceptual al inicio de la clase en cada curso donde se trate el tema, el alumno adquiere una visión general del mismo, continuando la clase con la profundización de los temas específicos de cada área. Abstract in english In this work the advantages of using concept maps as a tool in covering the same subjects in different courses of Agronomy Engineering are shown. The selected topic to construct the concept map is the Fusarium ear blight (FEB), a fungal disease that affects ear wheat and it appears with particular e [...] nvironmental conditions. The concept map of FEB was developed using the concepts extracted from the textbooks used in different courses and applying the software CmapTools. Finally, the map was exported to Web page format so all the students could access it from their own computer. It is concluded that using the concept map at the beginning of the class in each course where the selected concept is treated, students can get a global vision of it, to then deal with the specific subjects of the course in depth.

    Full Text Available La ablación de la taquicardia ventricular está adquiriendo gran importancia en el tratamiento de la taquicardia ventricular incesante así como en la reducción y prevención de episodios en pacientes con taquicardia ventricular monomorfa sostenida. El abordaje convencional requiere la inducción de la [...] taquicardia ventricular y la tolerancia de la misma durante el procedimento. Sin embargo, en muchos pacientes con taquicardia ventricular, en contexto de un infarto previo, no es factible la inducción de la taquicardia clínica, la inducción presenta baja reproducibilidad, la taquicardia se acompaña de inestabilidad hemodinámica o se presentan múltiples morfologías con variaciones espontáneas de una morfología a otra que dificultan el mapeo durante la taquicardia. Para superar a estas limitaciones, se han desarrollado las técnicas de mapeo y ablación de sustrato en ritmo sinusal, que actualmente se llevan a cabo en muchos centros. Esta revisión se centra en los avances realizados en los últimos años en el campo de la ablación de sustrato de la taquicardia ventricular en el paciente con cardiopatía estructural. Abstract in english Catheter ablation of ventricular tachycardia (VT) currently has an important role in the treatment of incessant ventricular tachycardia and reduction of the number of episodes of recurrent ventricular tachycardia. Conventional mapping techniques require ongoing tachycardia and haemodynamic stability [...] during the procedure. However, in many patients with scar-related ventricular tachycardia, non-inducibility of clinical tachycardia, poor induction reproducibility, haemodynamic instability, and multiple ventricular tachycardias with frequent spontaneous changes of morphology, preclude tachycardia mapping. To overcome these limitations, new strategies for mapping and ablation in sinus rhythm (SR) - substrate mapping strategies - have been developed and are currently used by many centres. This review summarizes the progresses recently achieved in the ablative treatment of ventricular tachycardia using a substrate mapping approach in patients with structural heart disease.

  1. Novel concepts and strategies in anticancer metallodrug development : towards oral activity, peptide conjugation and mass spectrometric applications

    International Nuclear Information System (INIS)

    Some ruthenium and osmium complexes are promising anticancer drug candidates and the preparation of organometallic RuII and OsII complexes, stabilized by a ?6-coordinating arene, represents the latest strategy for obtaining anticancer active metallodrugs with an intriguing activity profile. This PhD thesis reports on the discovery of novel tumour-inhibiting RuII– and OsII–arene metallodrugs and on studies aimed at understanding the molecular interactions of established anticancer agents and drug candidates with biomolecules. Although this field of research is intensely investigated, S,N-bidentate ligand-containing RuII and OsII metallodrugs are reported for the first time. The ligands are based on 2-pyridinecarbothioamides, which show activity as gastric mucosal protectants and are largely non-toxic in vivo (J. Med. Chem., 1990, 33, 327–336). Complexation to the organometallic moiety, however, yields highly cytotoxic metallodrugs in the chemoresistant colon carcinoma and multidrug-resistant non-small lung cancer cell lines. Their aqueous behaviour and drug-likeness properties suggest that this novel family of organometallic anticancer agents may be suitable for oral administration. Additionally, studies with the nucleosome core particle showed that these metallodrugs bind exclusively to the histone proteins at histone dimer–dimer and dimer–tetramer interfaces and therefore, may interfere with chromatin dynamics as a possible mode of action. Organometallic RuII–arene metallodrugs based on O,O-bidentate pyronato ligands typically show low antiproliferative activity. Intriguingly, triazolyl-modified pyrones coordinated to RuII–p-cymene yield highly cytotoxic agents in vitro. The strategy of triazolyl modification was followed to prepare the first organometallic Ru–peptide bioconjugate with cytotoxic activity in the low micromolar range in an ovarian cancer cell line. The metal–peptide bioconjugate was thoroughly characterized by different methods including top-down electrospray ionization-mass spectrometry (ESI-MS). Mass spectrometry is an invaluable tool in the analysis of molecular interactions between metallodrugs and biomolecules, such as DNA or proteins and their constituents. Furthermore, the molecular reactivity may give insight into the mode of action of a particular metallodrug or family of metallodrugs. Within the frame of this Ph.D. thesis, mass spectrometric techniques have been used to characterize the reactivity of representative (thio)pyr(id)onato RuII–p-cymene metallodrugs towards amino acids, nucleotides and proteins and an inverse correlation was found between extent of protein binding and antiproliferative activity, at least for these families of metallodrugs. Furthermore, the analysis of metallation sites of metallodrugs on proteins by mass spectrometric methods poses significant challenges in many cases due to low adduct detection efficiencies. Top-down mass spectrometric analysis is a promising approach to determine oxaliplatin binding sites on ubiquitin and different fragmentation techniques were investigated with the combination of higher energy C-trap dissociation (HCD) and electron transfer dissociation (ETD) tandem mass spectrometry yielding the highest information content. This approach led to the confirmation of methionine-1 as the primary and histidine-68 as the secondary binding site. (author)

    The Common Core State Standards (CCSS) provide a consistent, clear understanding of what students are expected to learn, so teachers and parents know what they need to do to help them. In 2010 the standards were designed to be robust and relevant to the real world, reflecting the knowledge and skills that young people need for success in college and careers. In 2013 the Next Generation Science Standards (NGSS) in connection with the CCSS developed revised science standards in performance, prior standards documents listed what students should know or understand, foundations were each performance expectation incorporates all three dimensions from a science or engineering practice, a core disciplinary idea, and a crosscutting concept, and coherence that connects each set of performance expectations lists connections to other ideas within the disciplines of science and engineering. Elizabeth City State University (ECSU) in Elizabeth City, North Carolina has joined with the University of New Hampshire (UNH) in Durham, New Hampshire under the NASA Innovations in Climate Education (NICE) grant to empower faculty of education programs at Minority Serving Institutions (MSIs) to better engage their pre-service teachers in teaching and learning about global climate change through the use of NASA Earth observation sets. Specifically, professors from MSIs received training with Global Positioning Systems (GPS) and GES-DISC Interactive Online Visualization And aNalysis Infrastructure (GIOVANNI) to engage pre-service teachers in facets of climate education. Grambling State University faculty members served as participants of the NICE workshop for 2012 and were encouraged to develop lessons in climate education from information shared at the workshop. A corresponding project that incorporated the CCSS and NGSS at Grambling State University in Grambling, Louisiana was headed by Dr. Loretta Jaggers. This paper documents activities that pre-service students in the GSU Curriculum and Instruction Department (College of Education) ED 452-Advanced Seminar Methods course have implemented. Activities included: Critique of Climate Education (oceans) articles, Methodology instruction; and design of a grade specific daily science lesson plan based on Climate Education that focused on El Nino, La Nina, seasonal characteristics of the southern oceans and resources from a NASA NICE workshop packet. Lessons designed were implemented on-site of partner secondary schools. The implementation included a virtual component as Grambling and ECSU students interacted via a polycom environment during reports from ED 452-Advanced Seminar Methods students.

    Benthic habitats on the Basque continental shelf were mapped based on multibeam echosounder surveys, grab sampling, video surveys and oceanographic monitoring. A total area of 2302 km2 was classified according to the European Nature Information System (EUNIS) hierarchical classification. Almost 50% of the area corresponded to rock and other hard substrata and the other 50% corresponded to soft bottoms. The biotic composition of several areas was significantly different from the EUNIS habitat classes described previously; therefore, we propose a total of 13 new classes. The habitat mapping has contributed to improving the knowledge and application of several criteria and indicators used to assess environmental status in the European Marine Strategy Framework Directive in relation to the biological diversity descriptors, such as non-indigenous species and seafloor integrity. It is also useful for other descriptors and for developing the sampling design.

  5. The science knowledge, conceptions of the nature of science, attitudes about teaching science, and science instructional strategies of bilingual and English-only elementary teachers

    Alegria, Adelina Victoria

    The goal of this study was to explore bilingual and English-only elementary teachers' science knowledge, their conceptions of the nature of science, their attitudes about teaching science, and their self-reported science instructional skills. In this study, a bilingual teacher was defined as a teacher who provides instruction in Spanish and English in core academic subjects and has completed and/or is completing a bilingual certification program. An English-only teacher was defined as a monolingual teacher that only speaks and instructs in English. The principal questions guiding this dissertation investigation were the following: How do bilingual elementary teachers differ from English-only elementary teachers in (a) their science knowledge, (b) their conceptions of the nature of science, (c) their attitude about teaching science, and (d) their self-reported science instructional skills? This dissertation study is a component of a three-year long Eisenhower Project granted to Hueneme School District and the University of California, Santa Barbara Southcoast Science Project. While the Project will last three years (1997--2000), this dissertation study was developed to answer only a subset of questions of the entire project and data was collected in 1998. The research design for this study consisted of a self-administered questionnaire that was given to Hueneme School District elementary teachers that teach science and was developed by reviewing the relevant literature about teachers' science knowledge, their conceptions of the nature of science, their attitudes about teaching science, and the instructional strategies that support science learning. The findings showed that both the bilingual and the English-only respondents demonstrated a similar science knowledge base, which is suggested, by this researcher, to be limited. That both bilingual and English-only teacher respondents demonstrated similar positive attitudes about teaching science and both reported making use of similar instructional strategies, many of which are known to support science learning in the classroom (laboratory/hands-on activities, whole group discussion, questioning, and cooperative/small group activities). Concerning assessment strategies, both the bilingual and English-only groups reported very similar answers. They reported usually making use of students' projects, student's logs/journals/diaries, performance activities such as lab practicals and hands-on tests to assess science learning. They also reported seldom or never making use of paper/pencil quizzes nor end-of-chapter/unit tests. There was not enough clear information to decide whether bilingual and English-only elementary respondents hold similar or different views of science. This study's implications encompass two different areas: (a) changes that bilingual and elementary credentialing programs need to undergo and (b) further bilingual science teaching research. The findings concerned with science knowledge, that both bilingual and English-only elementary teachers possess a limited science knowledge base leads me to suggest, just as the science teaching literature has suggested, that elementary credentialing programs need to strengthen their candidates' science content by increasing the science content addressed in the science methodology courses and/or by requiring a greater number of science undergraduate courses (most liberal arts majors require no more than five courses, San Diego State University, 1999).

    During drug discovery and development, the early identification of adverse effects is expected to reduce costly late-stage failures of candidate drugs. As risk/safety assessment takes place rather late during the development process and due to the limited ability of animal models to predict the human situation, modern unbiased high-dimensional biology readouts are sought, such as molecular signatures predictive for in vivo response using high-throughput cell-based assays. In this theoretical proof of concept, we provide findings of an in-depth exploration of a single chemical core structure. Via transcriptional profiling, we identified a subset of close analogues that commonly downregulate multiple tubulin genes across cellular contexts, suggesting possible spindle poison effects. Confirmation via a qualified toxicity assay (in vitro micronucleus test) and the identification of a characteristic aggregate-formation phenotype via exploratory high-content imaging validated the initial findings. SAR analysis triggered the synthesis of a new set of compounds and allowed us to extend the series showing the genotoxic effect. We demonstrate the potential to flag toxicity issues by utilizing data from exploratory experiments that are typically generated for target evaluation purposes during early drug discovery. We share our thoughts on how this approach may be incorporated into drug development strategies. PMID:26313431

    One third of people diagnosed with PD do not complete treatment and non-completion is associated with poorer clinical outcomes. Equipping staff to be better able to engage this client group is important, and web-based, self-directed learning is a potentially cost-effective way to train staff. This study examined the implementation of a web-based training programme called Readiness Enhancement Management Strategies (REMS) in three types of service. Completion rates were 94.4% in community health services; 92.3% in prison offender health services; and 46.5% in probation services. Staff found the content of REMS acceptable and useful. This study demonstrated that staff in NHS and criminal justice settings can complete REMS, but staff in probation services are challenged by time pressures and limited computer access. Staff at probation sites were less familiar with PD issues compared with the NHS staff. A web-based staff training programme called Readiness Enhancement Management Strategies (REMS) was developed to promote the engagement of people with personality difficulties in treatment. This 'proof of concept' study examined the REMS implementation process, its acceptability and the feasibility of using service data for future evaluation. Staff in six services working with people diagnosed with personality disorder or undiagnosed people with personality difficulties were eligible to participate: two community health services, two prison offender health services and two probation services. Of 92 eligible staff, 74 were available to undertake REMS. These staff completed knowledge and acceptability surveys and rated service user engagement with treatment. The proportion of treatment sessions attended by service users was collected for a 30-week period. REMS completion rates were community - 94.4%, prison - 92.3% and probation - 46.5%. Three quarters of participants rated REMS as 7 out of 10 or higher. All teams were able to provide service data for the study period. REMS can be implemented by National Health Services (NHS) staff in community and prison settings, but technology issues need to be resolved in probation services. REMS may be useful for NHS staff working with difficult to engage clients, and an evaluation is a feasible prospect. PMID:25977077

    The COP9 signalosome (CSN) is a multi-subunit protein complex that performs critical roles in controlling diverse cellular and developmental processes. Aberrant regulation of the CSN complex has been shown to lead to tumorigenesis. Despite its biological significance, our current knowledge of the function and regulation of the CSN complex is very limited. To explore CSN biology, we have developed and employed a new version of the tag team-based QTAX strategy (quantitative analysis of tandem a...

    Both canonical and alternative splicing of RNAs are governed by intronic sequence elements and produce transient lariat structures fastened by branch points within introns. To map precisely the location of branch points on a genomic scale, we developed LaSSO (Lariat Sequence Site Origin), a data-driven algorithm which utilizes RNA-seq data. Using fission yeast cells lacking the debranching enzyme Dbr1, LaSSO not only accurately identified canonical splicing events, but also pinpointed novel, but rare, exon-skipping events, which may reflect aberrantly spliced transcripts. Compromised intron turnover perturbed gene regulation at multiple levels, including splicing and protein translation. Notably, Dbr1 function was also critical for the expression of mitochondrial genes and for the processing of self-spliced mitochondrial introns. LaSSO showed better sensitivity and accuracy than algorithms used for computational branch-point prediction or for empirical branch-point determination. Even when applied to a human data set acquired in the presence of debranching activity, LaSSO identified both canonical and exon-skipping branch points. LaSSO thus provides an effective approach for defining high-resolution maps of branch-site sequences and intronic elements on a genomic scale. LaSSO should be useful to validate introns and uncover branch-point sequences in any eukaryote, and it could be integrated into RNA-seq pipelines. PMID:24709818

    2005-03-01

    Motivated by studies on -deformed physical systems related to quantum group structures, and by the elements of Tsallis statistical mechanics, the concept of -deformed nonlinear maps is introduced. As a specific example, a -deformation procedure is applied to the logistic map. Compared to the canonical logistic map, the resulting family of -logistic maps is shown to have a wider spectrum of interesting behaviours, including the co-existence of attractors – a phenomenon rare in one-dimensional maps.

  1. Spectroscopic mapping and selective electronic tuning of molecular orbitals in phosphorescent organometallic complexes – a new strategy for OLED materials

    2014-01-01

    Summary The improvement of molecular electronic devices such as organic light-emitting diodes requires fundamental knowledge about the structural and electronic properties of the employed molecules as well as their interactions with neighboring molecules or interfaces. We show that highly resolved scanning tunneling microscopy (STM) and spectroscopy (STS) are powerful tools to correlate the electronic properties of phosphorescent complexes (i.e., triplet emitters) with their molecular structure as well as the local environment around a single molecule. We used spectroscopic mapping to visualize several occupied and unoccupied molecular frontier orbitals of Pt(II) complexes adsorbed on Au(111). The analysis showed that the molecules exhibit a peculiar localized strong hybridization that leads to partial depopulation of a dz² orbital, while the ligand orbitals are almost unchanged. We further found that substitution of functional groups at well-defined positions can alter specific molecular orbitals without influencing the others. The results open a path toward the tailored design of electronic and optical properties of triplet emitters by smart ligand substitution, which may improve the performance of future OLED devices.

    Full Text Available Abstract Background Learning strategies are thinking tools that students can use to actively acquire information. Examples of learning strategies include mnemonics, charts, and maps. One strategy that may help students master the tsunami of information presented in medical school is the mind map learning strategy. Currently, there is no valid and reliable rubric to grade mind maps and this may contribute to their underutilization in medicine. Because concept maps and mind maps engage learners similarly at a metacognitive level, a valid and reliable concept map assessment scoring system was adapted to form the mind map assessment rubric (MMAR. The MMAR can assess mind map depth based upon concept-links, cross-links, hierarchies, examples, pictures, and colors. The purpose of this study was to examine interrater reliability of the MMAR. Methods This exploratory study was conducted at a US medical school as part of a larger investigation on learning strategies. Sixty-six (N = 66 first-year medical students were given a 394-word text passage followed by a 30-minute presentation on mind mapping. After the presentation, subjects were again given the text passage and instructed to create mind maps based upon the passage. The mind maps were collected and independently scored using the MMAR by 3 examiners. Interrater reliability was measured using the intraclass correlation coefficient (ICC statistic. Statistics were calculated using SPSS version 12.0 (Chicago, IL. Results Analysis of the mind maps revealed the following: concept-links ICC = .05 (95% CI, -.42 to .38, cross-links ICC = .58 (95% CI, .37 to .73, hierarchies ICC = .23 (95% CI, -.15 to .50, examples ICC = .53 (95% CI, .29 to .69, pictures ICC = .86 (95% CI, .79 to .91, colors ICC = .73 (95% CI, .59 to .82, and total score ICC = .86 (95% CI, .79 to .91. Conclusion The high ICC value for total mind map score indicates strong MMAR interrater reliability. Pictures and colors demonstrated moderate to strong interrater reliability. We conclude that the MMAR may be a valid and reliable tool to assess mind maps in medicine. However, further research on the validity and reliability of the MMAR is necessary.

    Full Text Available Este artigo apresenta os resultados de uma investigação dirigida ao delineamento dos principais problemas (bio)éticos identificados pelos membros das equipes da Estratégia Saúde da Família (ESF) do município de Viçosa (MG). Trata-se de estudo com abordagem qualitativa, situando-se no campo da pesqui [...] sa social. A investigação foi realizada por meio da aplicação de questionário semiestruturado com perguntas abertas e fechadas aos profissionais - médicos, profissionais de enfermagem e agentes comunitários de saúde - que atuam na ESF. Realizouse a apreciação das respostas pela técnica de análise de conteúdo - mais especificamente, sua modalidade temática -, em razão de sua adequação à investigação qualitativa na área da saúde. Participaram da investigação 73 profissionais de 15 equipes da ESF. Observou-se que grande parte dos entrevistados tinha dificuldade para identificar problemas de cunho (bio)ético em seu processo de trabalho. Ainda assim, foi possível categorizar cinco grandes grupos de problemas (bio)éticos vivenciados pelas equipes: os relacionados à desigualdade de acesso aos serviços de saúde; os relacionados à relação ensino-trabalho-comunidade; os relacionados ao sigilo e à confidencialidade; os relacionados aos conflitos entre equipe e usuários; e os relacionados aos conflitos entre membros da equipe. Conclui-se que, mesmo que aparentemente mais sutis - se comparados às questões (bio)éticas que se passam nas instituições hospitalares -, existem situações de conflitos morais atinentes ao âmbito da atenção primária à saúde que corroem o processo de trabalho e o alcance da promoção da integralidade do cuidado. Abstract in english This article presents the results of an investigation aimed at outlining the main (bio)ethical problems identified by members of the Family Health Strategy (FHS) teams in the town of Viçosa, Minas Gerais, Brazil. This study has a qualitative approach, and it is situated in the social research field. [...] The investigation was conducted by applying a semi-structured questionnaire with open and closed questions to professionals - physicians, nursing professionals, and community health workers - working in the FHS. The responses were addressed using the content analysis technique - more specifically, its thematic modality -, due to its suitability for qualitative investigation in the health field. The investigation relied on the participation of 73 professionals from 15 FHS teams. It was observed that a large part of respondents had some difficulty identifying problems of a (bio)ethical nature in their work process. Even so, it was possible to categorize five major groups of (bio)ethical issues experienced by teams: those related to unequal access to health services; those related to the teaching-work-community relation; those related to secrecy and confidentiality; those related to conflicts between team and users; and those related to conflicts between team members. It is concluded that, although apparently more subtle - when compared to the (bio)ethical issues taking place in hospital institutions -, there are moral conflict situations belonging to the domain of primary health care that undermine the work process and the scope of promoting comprehensiveness in care.

    Full Text Available [english] Aims: Despite many efforts by support groups, mental health professionals and health care policy-makers, a stigmatization of psychiatry as a specialty and of mentally ill people is still prevalent in the general population. Earlier studies have shown that the stigma is prevalent even among psychiatric professionals and students of medicine and psychology. However, past studies on this issue often used questionnaires with a limited validity. Also questionnaires do not necessarily allow a neutral assessment of the underlying concepts of the student. Methods: In this study 133 students were asked to create mind maps on psychiatry. Results: In a systematic evaluation (based on a consensus of psychiatric concepts of 1353 concepts we found non-specific associations (N = 431 and five main categories: (i illness scirpts (n = 487; (ii therapeutic concepts (n = 241, (iii and (iv stigma and forensic psychiatry (81 mentions each; and (v psychopathology (n = 32. Stigma-associated negative concepts were more prevalent than positive connotations. Conclusions: Overall, it was shown that mind maps can be used with ease and quantified according to constructivist learning theory to explore disease concepts without the need for predefined or poorly validated questionnaires.[german] Zielsetzung: Trotz vieler Bemühungen, u. a. von Selbsthilfegruppen, der Fachgesellschaft und der Gesundheitspolitik gibt es in der Allgemeinbevölkerung immer noch eine Stigmatisierung der Psychiatrie als Fachgebiet. Frühere Untersuchungen zeigten, dass auch in der Psychiatrie tätige Menschen und Studierende der Medizin und Psychologie stigmatisierenden Äußerungen zustimmen. Zur genaueren Betrachtung wurden in der Vergangenheit jedoch meist Fragebögen verwendet, die eine begrenzte Validität haben und nicht zwangsläufig eine neutrale Beurteilung der zugrundeliegenden Konzepte der Studierenden erlauben.Methodik: In der vorliegenden Studie wurden 133 Studierende gebeten, Mind-Maps zum Thema Psychiatrie zu erstellen.

    The Baden-Wuerttemberg Council on Sustainable Development (Stuttgart, Federal Republic of Germany) presents a climate expert report with new concepts for a globally effective climate protection. First of all, the development of the global emissions of carbon dioxide since 1990 is described. The development of the global emissions of carbon dioxide up to 2050 is forecasted. Four general criteria (effectiveness, efficiency, fairness and acceptance) for a comparative evaluation of climate protection concepts are introduced. A proposal for solution on the basis of a globally effective cap-and-trade system as well as an identical scenario as an alternative with respect to the implementation are described. This alternative scenario is based on a cap-and-trade system but it develops on the basis of national self-commitment in accordance with an incentive and sanctionative system. Both implementation proposals are compared. Recommendations of the national government Baden-Wuerttemberg are given.

    Gwinner, Klaus; Jaumann, Ralf

    2015-04-01

    The High Resolution Stereo Camera (HRSC) of ESA's Mars Express mission is designed to map and investigate the topography of Mars. As the surface areas with contiguous coverage by stereo data are increasingly abundant, the HRSC team has recently started a coordinated effort for the systematic mapping of Mars by multi-orbit digital terrain models (DTMs) and image mosaics, using the complete HRSC mission data record. We present the DTM and orthoimage mosaic obtained for the first half-tile, MC-11E (Eastern Oxia Palus), together with results of a performance analysis for this data set. The geomorphological analysis of surface features observed by HRSC has allowed to characterize major surface modifications by endogenic and exogenic processes at different scales. Such studies (in the field of geomorphology, but also compositional mapping and atmospheric science) have been based on joint analysis of DTM and orthoimage information, and have benefitted from the high accuracy of co-registration between multiple datasets, which is particularly important for multi-temporal and multi-angular observations. HRSC is unique because it bridges the gap between laser altimetry and topography data derived from other stereo imaging instruments, and provides geodetic reference data and geological context to a variety of stereo and non-stereo datasets. As HRSC is a push broom scanning instrument with nine CCD line detectors mounted in parallel, its unique feature is the ability to obtain along-track stereo images and four colors during a single orbital pass. The sub-pixel accuracy of 3D points derived from stereo analysis allows producing DTMs with grid sizes of up to 50 m and a height accuracy on the order of one pixel on the ground and better, as well as corresponding orthoimages. Such data products have been produced for individual HRSC strips covering approximately 40% of the surface of Mars so far. After more than 10 years of operation, HRSC covered about 70% of the surface by panchromatic images with 10-20 m/pixel, and about 98% with better than 100 m/pixel. The new global mapping program is based on the USGS MC-30 quadrangle scheme, where quadrangles are split into eastern and western parts to limit data volumes. We provide an overview of relevant methods and standards applied for 3D reconstruction, block adjustment and mapping, including radiometric image processing. We demonstrate that multi-orbit DTMs with grid spacing of 50 m are feasible for large surface areas in spite of the existing variation of ground pixel size. After bundle block adjustment, image mosaics and DTMs can demonstrably benefit from co-registration accuracy of adjacent strips on the order of one pixel, and at the highest image resolution available. On average, the adjustment to Mars Orbiter Laser Altimeter (MOLA) heights used as global geodetic reference is achieved at the same accuracy as for single-strip DTMs. After a photometric normalization and by using Thermal Emission Spectrometer (TES) albedo as a brightness standard, it is possible to produce visually consistent image mosaics from HRSC images acquired under very different illumination and atmospheric conditions due to seasonal and day-time variation.

This paper presents the systematic development of the teachers' trainings executed in the ToyBox-intervention - a kindergarten-based and family-involved obesity prevention programme for children aged 4-6. Based on concepts for the education of kindergarten teachers, on general strategies for successful programme implementation and on the ToyBox programme-specific requirements, the aims of the teachers' trainings were defined and an overall concept was deduced. Regarding the concept for the ToyBox teachers' training sessions, it is concluded that the training modules should focus on presenting information on the practical implementation of the intervention. Furthermore, these modules should also include self-efficacy enhancing components and should give kindergarten teachers opportunities to share experiences. Regarding the didactic methods applied in the ToyBox teachers' training sessions, constructivist learning approaches that facilitate active participation, reflective thinking and personal involvement were implemented. Emphasis was put not only on the content but especially on the didactic methods of teachers' trainings in order to enhance devotion to, and quality and sustainability of the ToyBox-intervention.

    Gartenberg, Ehud

    1995-09-01

    A conceptual study was performed to define a technique for mapping the boundary-layer transition on a 10 deg-Cone in the National Transonic Facility (NTF) as a means of determining this cryogenic-tunnel suitability for laminar flow testing. A major challenge was to devise a test matrix using a fixed surface pitot probe, varying the flow pressure to pr oduce the actual Reynolds numbers for boundary-layer transition. This constraint resulted from a lack of a suitable and reliable electrical motor to drive the probe along the cone's surface under cryogenic flow conditions. The initial phase of this research was performed by the author in collaboration with the late Dr. William B. Igoe from the Aerodynamics Division at NASA Langley Research Center. His comments made during the drafting of this document were invaluable and a source of inspiration.

  18. Updated strategy and test of new concepts for groundwater flow modelling in Forsmark in preparation of site descriptive modelling stage 2.2

    International Nuclear Information System (INIS)

    As part of the preliminary Site Descriptive Modelling (SDM version 1.2) for the Initial Site Investigation (ISI) stage at Forsmark, Simpevarp and Laxemar, a methodology was developed for constructing hydrogeological models of the crystalline bedrock. The methodology achieved reasonable success given the restricted amounts and types of data available at the time. Notwithstanding, several issues of concern have surfaced following the reviews of the preliminary site descriptions of the three sites. Possible solutions to parts of the problems have been discussed internally for a longer time and an integrated view and strategy forward has been formulated. The 'new strategy' is not a complete shift in methodology, however, but a refocusing on and clarification of the key aspects that the hydrogeological SDM needs to accomplish. In broad terms the basic principle of the 'new strategy' suggested is to develop an overall conceptual model that first establishes the major flowing deformation zones, and then gradually approaches determination of the hydraulic properties of the bedrock outside these zones in the potential repository volume. On each scale, the focus of the description should be on features/structures of significance on that scale. Clearly, a detailed (although statistical) description of the repository and canister deposition hole scale is the end goal, but this approach (which also is more the traditional approach in hydrogeology) is judged to provide a much better motivated overall geometrical description. Furthermore, the 'new strategy' puts more emphasis on field testing (e.g. interference tests) and data analyses and less on numerical simulation and calibration. That is, before extensive (and costly) simulations and model calibrations are made it needs to be clearly understood what could be the potential gains of carrying them out. This report presents the conceptual model development for Forsmark in preparation of the site descriptive modelling in stage 2.2. Four 'pre-modelling' exercises have been performed to develop and test the methodology issues. These exercises are not directly aimed at a model update, but more intended to provide some insight into new aspects of the modelling methodology and the use of field data, and therefore provide background support also for the upcoming final SDM. Some of the issues treated for the SDM of the Forsmark site are also of interest for the SDM of the Laxemar site

    Full Text Available Abstract Background There is ample evidence that residential neighbourhoods can influence mental well-being (MWB, with most studies relying on census or similar data to characterize communities. Few studies have actively investigated local residents’ perceptions. Methods Concept mapping was conducted with residents from five Toronto neighbourhoods representing low income and non-low income socio-economic groups. These residents participated in small groups and attended two sessions per neighbourhood. The first session (brainstorming generated neighbourhood characteristics that residents felt influenced their MWB. A few weeks later, participants returned to sort these neighbourhood characteristics and rate their relative importance in affecting residents’ ‘good’ and ‘poor’ MWB. The data from the sorting and rating groups were analyzed to generate conceptual maps of neighbourhood characteristics that influence MWB. Results While agreement existed on factors influencing poor MWB (regardless of neighbourhood, income, gender and age, perceptions related to factors affecting good MWB were more varied. For example, women were more likely to rank physical beauty of their neighbourhood and range of services available as more important to good MWB, while men were more likely to cite free access to computers/internet and neighbourhood reputation as important. Low-income residents emphasized aesthetic attributes and public transportation as important to good MWB, while non-low-income residents rated crime, negative neighbourhood environment and social concerns as more important contributors to good MWB. Conclusion These findings contribute to the emerging literature on neighbourhoods and MWB, and inform urban planning in a Canadian context.

  5. Explorers of the Universe: Metacognitive Tools for Learning Science Concepts

    Alvarez, Marino C.

    1998-01-01

    Much of school learning consists of rote memorization of facts with little emphasis on meaningful interpretations. Knowledge construction is reduced to factual knowledge production with little regard for critical thinking, problem solving, or clarifying misconceptions. An important role of a middle and secondary teacher when teaching science is to aid students' ability to reflect upon what they know about a given topic and make available strategies that will enhance their understanding of text and science experiments. Developing metacognition, the ability to monitor one's own knowledge about a topic of study and to activate appropriate strategies, enhances students' learning when faced with reading, writing and problem solving situations. Two instructional strategies that can involve students in developing metacognitive awareness are hierarchical concept mapping, and Vee diagrams. Concept maps enable students to organize their ideas and reveal visually these ideas to others. A Vee diagram is a structured visual means of relating the methodological aspects of an activity to its underlying conceptual aspect in ways that aid learners in meaningful understanding of scientific investigations.

  6. Integrating Software Architecture Concepts into the MDA Platform with UML Profile

    Full Text Available Architecture Description Languages (ADLs provide an abstract representation of software systems. Achieving a concrete mapping of such representation into the implementation is one of the principal aspects of MDA (Model Driven Architecture. Integration of ADLs within MDA confers to the MDA platform a higher level of abstraction and a degree of reuse of ADLs. Indeed they have significantly different platform metamodels which make the definition of mapping rules complex. This complexity is clearly noticeable when some software architecture concepts cannot be easily mapped to MDA platform. In this research, we propose to integrate software architecture within MDA. We define also strategy for direct transformation using a UML profile. It represents both software architecture model (PIM and MDA platform model (PSM in UML meta-model then elaborates transformation rules between results UML meta-models. The goal is to automate the process of deriving implementation platform from software concepts.

    Based on a theoretical overview and empirical observations, the paper discusses a variety of concepts of strategy. The main argument is that even though the concepts of strategy mostly reflect the perception of science at the macro-sociological level, the research field of strategy seems keen on mixing paradigms. The paper arrives at the argument that contemporary scholarly activities may benefit from viewing strategy as a dialectical phenomenon in terms of a continuous transposition of managerial decision making situations.

    In this book we study the concepts of Fuzzy Cognitive Maps (FCMs) and their Neutrosophic analogue, the Neutrosophic Cognitive Maps (NCMs).Fuzzy Cognitive Maps are fuzzy structures that strongly resemble neural networks, and they have powerful and far-reaching consequences as a mathematical tool for modeling complex systems. Neutrosophic Cognitive Maps are generalizations of FCMs, and their unique feature is the ability to handle indeterminacy in relations between two concepts thereby bringing greater sensitivity into the results. Some of the varied applications of FCMs and NCMs which has been explained by us, in this book, include: modeling of supervisory systems; design of hybrid models for complex systems; mobile robots and in intimate technology such as office plants; analysis of business performance assessment; formalism debate and legal rules; creating metabolic and regulatory network models; traffic and transportation problems; medical diagnostics; simulation of strategic planning process in intelligent...

  10. Mapping out Map Libraries

    2008-09-01

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

  11. A strategy for an SIT-based area-wide intervention against tsetse in South Africa: The concept, requirements and future prospects

    International Nuclear Information System (INIS)

    The tsetse in KwaZulu-Natal (KZN) represents the southern most limit of Glossina distribution in Africa. The severe outbreak of animal African trypanosomosis in 1990, which resulted in high cattle mortalities in the communal farming areas, was mainly attributed to the presence of the two tsetse species Glossina austeni and G. brevipalpis. The treatment of cattle with trypanocidal drugs combined with tsetse control efforts using insecticide pour-ons on livestock and odour-baited insecticide impregnated targets were successful to control the outbreak. The temporary nature of this approach was however, evidenced by the current prevalence of trypanosomosis, which has reverted to the high levels of 1990 before these temporary control measures were instigated. In 1992, the National Directorate of Veterinary Services (NDVS) contracted ARCOnderstepoort Veterinary Institute (ARC-OVI) to develop a long-term strategy to control G. brevipalpis and G. austeni. In view of the limitations of the applied approach monitoring of the disease, animal treatment and pyrethroid dipping/pour-ons), it has become obvious that the only sustainable, long-term solution to the trypanosomosis problem would be the complete elimination of the two vector species from KZN. A feasibility study was initiated to assess whether a sustainable solution to the tsetse and trypanosomosis problem in South Africa could be found through the creation of a tsetse free zone using the Sterile Insect Technique (SIT) as a component of an area-wide integrated pest management programme. A phased approach was adopted to ensure that all fundamental data and requirements, needed to develop a sound strategy, were available. Studies were carried out to develop a suitable odour-baited insecticide impregnated target system and a suitable trapping device to sample both tsetse species in adequate numbers. This was especially challenging for G. austeni in view of their reluctance to enter tsetse traps, which are efficient for other tsetse species. 'Sticky panels' were the only alternative available for sampling and monitoring purposes, but these are very cumbersome to use and not suitable for many ecological studies. A new sampling tool (H-trap) was therefore developed that proved to be suitable to implement monitoring activities and mark-release-recapture studies

    Full Text Available The paper presents findings from a comparative analysis of three major topical fields of interest notably supply chain management, technological progress and mass flux analysis in six European forest regions of the IN2WOOD project (FP7 RoK 2010-2012. The study identifies matching strengths and weaknesses and summarizes cross-regional priorities. Based on this information, a set of the region’s strategies was compiled in view of the general objective to optimise logistics. Four different strategy types were proposed: SO-strategy (internal strengths were used to realise external opportunities, WO-strategy (reducing internal weakness to realise external opportunities, ST-strategy (internal strengths were used to minimise external threats and WT-strategy (reducing the internal weaknesses to avoid external threats. Main common strategies for forestry logistics are: developing clear concepts for the implementation of ICT applications for difficult terrain like GPS-maps in mountainous regions, increasing the possibility of co-operations between the actors involved and developing a detailed mass flux analyses as a basis for SCM concepts.

    The cognitive architecture of concept is a specific structure consisting of the concept core, concept periphery, the semantic frame as the meaning and the sense of the concept, and the relations among all components of this structure. The model of the cognitive architecture of scientific and common concepts is a conceptual meta-model built upon Vygotsky's concept theory, Fillmore's semantic frame, semantic triangle, on widespread ideas of the structuring of conceptual systems, and the Hestenes' Modeling Theory. The method of semantic mapping of concepts flowing from the model is designed.

    Bandler, J. W.; Biernacki, R.

    1995-01-01

    We propose a significantly improved space mapping (SM) strategy for electromagnetic (EM) optimization. Instead of waiting for upfront EM analyses at several base points, our new approach aggressively exploits every available EM analysis, producing dramatic results right from the first step. We establish a relationship between the novel SM optimization and the quasi-Newton iteration for solving a system of nonlinear equations. Approximations to the matrix of first-order derivatives are updated by the classic Broyden formula. A high-temperature superconducting microstrip filter design solution emerges after only six EM simulations with sparse frequency sweeps. Furthermore, less CPU effort is required to optimize the filter than is required by one single detailed frequency sweep. We also extend the SM concept to the parameter extraction phase, overcoming severely misaligned responses induced by inadequate empirical models. This novel concept should have a significant impact on parameter extraction of devices.
