Case conceptualization, a term synonymous with case formulation, is an essential psychotherapy skill. Novice therapists enter into the practice of psychotherapy with limited case conceptualization skills. Hence, an important goal when supervising novice therapists is to effectively teach these skills. Concept mapping facilitates case conceptualization skills through the process of methodically creating graphic representations of clients' problems and dynamic relationships between these problems. This article introduces a highly structured and practical 4-stage approach to supervision that effectively introduces case formulation skills to novice therapists using concept mapping. It is assumed that concept maps, when shared with clients, function as an intervention to facilitate insight and change. PMID:25730627

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

Full Text Available Concept maps (CM are powerful tools which have different uses in educational contexts; however, this study limited its extension and explored its impact on the reading comprehension skill of Iranian EFL students. To this purpose, a proficiency test was employed and 90 intermediate pre-university students were chosen and divided into three groups: learner constructed CM group, fill in the map CM group, and summarizing strategy group. The whole study was conducted within three months. At the beginning of the study, a reading comprehension test (as a pre test was administered to measure the comprehension ability of the subjects. During the five-session treatment period, the assigned strategies were taught and practiced in each group. Then, another reading comprehension test (as a post test was employed to compare the effect of treatment on the comprehension skill. The results of the study showed that despite the efficacy of all three strategies, the fill in the map version of CM was the most influencing one. It suggested that in general, CM technique might be regarded as an alternative or even as an effective replacement of the summarizing strategy for reading comprehension skill.

A concept map is a two-dimensional, hierarchical node-link diagram that depicts the most important concepts and propositions in a knowledge domain. Concept mapping helps students and faculty recognize the difference between meaningful and rote learning, as well as aid in assessing and rewarding meaningful learning. Discussed are construction and scoring of concept maps, as well as research on validity and effectiveness of concept maps.
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.

Full Text Available Concept map is a device for representing the conceptual structure of asubject/discipline in a two-dimensional form, which is analogous to the road map. Aconcept, as defined by Novak, is regularity in objects or events designated by a specificlabel. Concept maps are diagrammatic representations, which show meaningfulrelationships between concepts in the form of propositions.Propositions are two or more concept labels linked by words, which provideinformation on relationships or describe connections between concepts.
This article describes a general concept mapping system that is open architecture for integration with other systems, scriptable to support arbitrary interactions and computations, and customizable to emulate many styles of map. The system supports collaborative development of concept maps across local area and wide area networks, and integrates with World-Wide Web in both client helper and server gateway roles. A number of applications are illustrated ranging through education, artificial intelligence, active documents, hypermedia indexing and concurrent engineering. It is proposed that concept maps be regarded as basic components of any hypermedia system, complementing text and images with formal and semi-formal active diagrams. Concept maps are often used as visual representations of student knowledge.

This page describes concept maps, one of a series of Classroom Assessment Techniques (CATs) provided by the Field-tested Learning Assessment Guide (FLAG) website. The CATs of FLAG were constructed as a resource for science, technology, engineering and mathematics instructors to emphasize deeper levels of learning and to give instructors valuable feedback during a course. A concept map is a diagram of nodes adjoined by directional lines and organized in hierarchical levels that move from general to specific concepts. Concept maps are used to assess how well students see the big picture, and to illustrate students' conceptual knowledge. This site provides an overview of this assessment instrument that includes information about how to use them. This site is also is linked to a set of discipline-specific tools that can be downloaded for immediate use, as well as supplementary links and sources to further explore this assessment tool.

Concept mapping is an inquiry technique that provides students at all ages with opportunities to demonstrate learning through performance. A concept map refers to a graphic/visual representation of concepts with linking connections that show various relationships between concepts (Novak & Gowin, 1984).

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.

Full Text Available Concept maps are used extensively as an assessment tool, and the literature is abundant with studies on the use of concept maps for assessment and on the assessment of concept maps. The assessment of concept maps can be an arduous process, in particular when assessing a large number of maps. CmapAnalysis is a software tool that facilitates performing various analysis measures on a collection of concept maps. A set of measures that consider size, quality and structure properties of the maps are included. The program is designed to be extensible, allowing users to add their own measures. The program is not intended to replace the individual evaluation of concept maps by teachers and instructors, as it does not capable of “understanding” the content of the maps. It is aimed at researchers who are looking for more general trends and measures across a large number of maps, and who can extend it with their own measures. The output of CmapAnalysis is an Excel spreadsheet that can be further analyzed.
At the end of the semester, students are asked to create a concept map of the four main concepts covered over the duration of the course. They are provided with a grading rubric and 4 the main nodes that are required on the map (plate tectonics, the rock cycle, geologic time and scientific research). The four concepts can be arranged in any manner, and the connecting lines must be labelled with appropriate terms and examples. Students have the option of creating a paper map (11'' x 17'' or larger) or a digital map using a free software program, VUE.
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.

Concept maps are widely used in education and business as a first step in knowledge sharing between the groups of people in communicate their complex idea and creativity. However, the mapping process is quite complex because all of the inherent ambiguity in aid creativity and ideation must be resolved to produce the facilitative tool for knowledge sharing model. This study has intended to show how concept map based knowledge models can be used as facilitator tools in create, locate and dissem...
Concept maps are a form of graphical knowledge representation . Concept maps are drawn as directed or undirected graphs. Concept maps may carry a large and complex structure where concepts are described as a form of relationships between the nodes and the edges. Concept maps are widely used in teaching and learning where educational research and assessment are necessary functions. The common problem when dealing with concept maps is evaluation. This usually involves comparing concept maps ...

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.
In this paper the scientific side of concept mapping is viewed as "soft science" and the artistic one as "hard art" to imply that the process has some qualities of both, but probably does not fall exclusively within either's domain. In the spirit of hard art, a "gallery" of final concept maps from twenty projects is presented, partly to illustrate more examples of the process when used in a variety of subject areas and for different purposes, and partly for their aesthetic value alone. In the spirit of soft science, two major issues are considered. First, the evidence for the validity and reliability of concept mapping is introduced, along with some suggestions for further research which might be undertaken to examine those characteristics. Second, the role of concept mapping is discussed, with special emphasis on its use in a pattern matching framework. This document is intended for use by novice evaluators and professional evaluators in workshops and conferences.

The goal of this thesis is to investigate methods for computerized tutoring support that is adapted to the individual student. In particular, we are concerned with providing such assistance to students solving exercises in domains where a complete or accurate problem-solving model is infeasible. We propose to do this by using concept maps as a means for students to model their own knowledge. Combined with results from earlier exercises, the concept map can form a student model that can be use...

Navigable concept maps are a type of graphical overview and a relatively new learning tool that may serve several interrelated functions while learners study online: as a graphic organizer, navigational tool, pathway indicator, actual material-to-be-learned, and a means to self-monitor and review during studying and at the end of a study period. Few studies have examined navigable concept maps, although many studies have investigated different types of organizers with varied learner control. ...

Nurse educators, under pressure to prepare graduates who are able to think critically and solve problems in a variety of clinical practice settings, require active teaching strategies to promote meaningful learning, instead of relying on traditional methods that promote rote memorization. A review of the current state of the science with regard to concept mapping demonstrates that this teaching-learning method assists nurse educators to prepare graduates to think critically in the complex health care environment. However, further research is needed to determine the effectiveness of concept mapping on the graduate's performance on the NCLEX exam and on critical thinking and prioritization skills in the clinical environment.

Full Text Available The paper presents the effect of a free word association test, content analysis and concept mapping on students’ achievements in human biology. The free word association test was used for revealing the scientific conceptual structures of 8th grade and 12th grade students, around a stimulus word – human being – and for motivating them to study human biology. The stimulus word retrieved a cluster of associations most of which were based on science education and experience. Associations with the stimulus word were analyzed and classified according to predetermined criteria and structured by means of a concept map. The stimulus word ‘human being’ was quantitatively assessed in order to find out the balance between the associations with its different aspects. On the basis of the results some connections between biology and other sciences studying the human being, were worked out. Each new topic in human biology was studied by using content analysis of the textbook and concept mapping as study tools and thus maintaining students’ motivation. Achievements of students were assessed by means of tests, observation and concept maps evaluation. The obtained data was also valuable in clarifying the complex nature of the human being, and confirming the statement that biology cannot answer all questions, concerning human nature. Inferences were made about the word association test combined with content analysis and concept map construction as an educational strategy.

Full Text Available Auto-monitoring is the pivotal concept in understanding the operation of concept maps, which have been used to help learners make sense of their study and plan learning activities. Central to auto-monitoring is the idea of a 'learning arena' where individuals can manipulate concept representations and engage in the processes of checking, resolving and confirming understandings. The learner is assisted by familiar metaphors (for example, networks and the possibility of thinking 'on action' while 'in action'. This paper discusses these concepts, and concludes by arguing that maps are part of the process of learning rather than a manifestation of learning itself. Auto-monitoring is suggested as an appropriate term to describe the process of engaging in the learning arena.

A concept map is a two-dimensional, graphic or schematic diagram illustrating the interconnections, and often the hierarchy, of a particular concept or topic. Concept maps are especially important in teaching science because they depict the interrelationships among the members of a group or a system. Concept maps are often used in science to represent ecosystems, mechanical systems, and social systems. This Toolkit column provides meaningful ways to make the most of concept maps, especially in the area of assessment.
Full Text Available In the present study, an attempt has been made to visualise relationships among concepts using concept maps. Identification and categorisation of relationships is a fundamental process in effective knowledge organisation and retrieval. This cognitive process of identification of relationships can be facilitated by generating concept maps. Basic concept maps have been developed for an interdisciplinary subject domain; accelerator driven systems (ADS. These concept maps can be used as aids for conceptualisation in a domain ontology.

One of the teaching methods that are carried out to make teaching-learning process more effective is concept mapping. Learners can incorporate new knowledge into their prior knowledge framework by utilizing concept mapping. Furthermore, representation and organization of the knowledge through concept maps, helps retention and recall. Thus concept maps facilitate meaningful learning by organizing knowledge in cognitive structure and encourage creative thinking. Concept maps constructed by the teachers, enable students identify and explore the structure and the nature of knowledge. The use of concept maps can also assist teachers in evaluating the process of teaching. This study aims to investigate the elementary teachers’ views on concept maps by using an open-ended questionnaire which is carried out with 24 elementary teachers. Before conducting the questionnaire teachers have been instructed about concept maps and they constructed concept map examples. The findings indicate that elementary teachers generally perceive concept maps as a useful, effective, practical tool and they highlighted concept maps as important since they provide feedback. An important implication of this study is that there is a need for teachers to know how to teach concept map construction, to associate the concept maps into their lessons and into the evaluating process.

Full Text Available The following work shows the conceptual map as an evaluation tool. In this study, an opening text was used as a previous organizer, with a theme related to the students’ daily lives. The developed activity consisted in elaborating conceptual maps before and after the experimental works. The evaluation was applied to 21 students of the 1st grade and 22 of the 3rd grade of High School. The elaborated maps were scored according to hierarchy, propositions, linking words, cross linking and examples. The classification of the maps elaborated before and after the experimental activity, was obtained having as a parameter, a referential conceptual map. In this classification many differences were observed between the first and second maps of both grades and among the groups. The elaboration of conceptual maps showed great potential as evaluation resources.

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

The concept map tool set forth by Novak and colleagues is underutilized in education. A meta-analysis has encouraged teachers to make extensive use of concept mapping, and researchers have advocated computer-based concept mapping applications that exploit hyperlink technology. Through an NSF sponsored geosciences education grant, middle and secondary science teachers participated in professional development to apply computer-based concept mapping in project-based learning (PBL) units that investigated local watersheds. Participants attended a summer institute, engaged in a summer through spring online learning academy, and presented PBL units at a subsequent fall science teachers' convention. The majority of 17 teachers who attended the summer institute had previously used the concept mapping strategy with students and rated it highly. Of the 12 teachers who continued beyond summer, applications of concept mapping ranged from collaborative planning of PBL projects to building students' vocabulary to students producing maps related to the PBL driving question. Barriers to the adoption and use of concept mapping included technology access at the schools, lack of time for teachers to advance their technology skills, lack of student motivation to choose to learn, and student difficulty with linking terms. In addition to mitigating the aforementioned barriers, projects targeting teachers' use of technology tools may enhance adoption by recruiting teachers as partners from schools as well as a small number that already are proficient in the targeted technology and emphasizing the utility of the concept map as a planning tool.

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.

Full Text Available The interesting paper by Dinarvand and Vaisi-Raygan (1 makes valuable points about a particularly challenging aspect of biochemistry learning and teaching. Their work prompts me to ask two questions and make a comment. First, what do the authors mean by a concept map (CM? A pathway map could be considered a CM, but a CM could cover modes of regulation and kinetics in relation to particular reactions or pathways and there are many other possibilities. Irrespective of this, a CM can get extremely complex if more than a few concepts are involved (2, as can be seen in examples given by Novak (3. This is the fundamental problem of teaching and learning biochemistry (4, which combines the network of pathways, compartmentation, macromol¬ecular structure, regulation, kinetics and some fairly sophisticated chemical concepts.Second, how did the students go about preparing CMs? My experience is that students prefer to use a computer for most tasks, but standard CM software (5 may not be suitable. For example, they often struggle unnec¬essarily to use software to prepare a graphical summary of the structural features of a protein, its precursors and the gene encoding it. This distracts them from the material. My suggestions that pencil and paper might be sufficient are usually met with amazement. Third, as Dinarvand and Vaisi-Raygan (1 make clear, a coherent summary of the metabolism considered in a course in metabolic biochemistry is crucial if students are to appreciate the pathways and their interconn-ection and regulation. For many years I have used an approach in which students collaborate in tutorials to achieve this. The sessions are usually initiated by me drawing the plasma membrane and the mitochondrial membranes on a large board and inviting the students to fill in the blanks (I provide large sheets of paper so that students can make copies. With coaxing, someone volunteers and I explain that the volunteer is not alone because everyone is expected to help and, eventually, everyone will be the volunteer. Thereafter, I act as moderator, provide support to any nervous students and, very rarely, offer some clarification, correction or suggestion. The sessions are very lively and highly productive. We usually spend one week going over the details of the reactions in all the pathways we have considered, and in the next tutorial we generate a simpler outline of the reactions and superimpose the regulation of the pathways. In addition to the generation of a coherent overview of the pathways and processes, the advantages of this approach include instant feedback on the suggestions made by students (often provided by other students; real discussion of the biochemistry; identification of particular points of difficulty; the voluntary inclusion of almost every student, which gives me some indication of those who might be struggling; and laughter. The feedback is consistently positive and students actually ask when the sessions are going to happen as we approach the end of semester. A similar approach works just as well when summarizing a semester’s work on cell and molecular biology.
Different significance of collaborative concept mapping and collaborative argumentation in Case Based Learning are discussed and compared in the different perspectives of answering focus questions, of fostering reflective thinking skills and in managing uncertainty in problem solving in a scaffolded environment. Marked differences are pointed out between the way concepts are used in constructing concept maps and the way meanings are adopted in case-based learning through guided argumentation ...

This paper describes CMEX Mars, an effort in the creation of a comprehensive set of concept maps to describe all aspects of Mars exploration. These concept maps, created using the CmapTools software developed by the Institute for Human and Machine Cognition, are available on the Internet at http:/cmex.arc.nasa.gov/CMEX and are linked among themselves as well as to resources on the Internet. The work described took place mainly between 1998 and 2001 and combined the goals of: 1) developing a library of concept maps for educational outreach while also 2) refining the capabilities of the software used to create the interactive maps and 3) making them available on the Internet. Here we focus on the library of Mars exploration concept maps that has been created.
In recent years, academics and educators have begun to use software mapping tools for a number of education-related purposes. Typically, the tools are used to help impart critical and analytical skills to students, to enable students to see relationships between concepts, and also as a method of assessment. The common feature of all these tools is…
The purpose of this study was to examine relationships between structural characteristics of students' concept maps about chemical equilibrium and independent measures of their achievement in chemistry. Fifty students in 1991 and seventy students in 1992 completed a concept-mapping task using twenty-four specified concepts. Using similarities in concept map structure, based on the presence or absence of linked pairs of concepts, non-metric multidimensional scaling (MDS) was used to plot the location of the concept maps in coordinate space. The distribution of maps was based on differences in their structure, but also reflected levels of student achievement on independent tests. The relationship between the coordinate location of each student's maps and his or her test scores on independent chemistry achievement tests was sought by canonical correlation analysis of the 1991 data set. This revealed significant relationships between the MDS coordinates and test scores of recall of knowledge and its application. Multiple regression analysis of sixty-one students' maps from the 1992 data set against their percentile rank scores on a national chemistry quiz revealed significant relationships. The results are interpreted as revealing structural differences in conceptual organisation about chemical equilibrium among students with different levels of achievement and thus relative expertise in the domain. The significant relationship between map structure and cognitive process scores in chemistry also supports the view that the organisation of declarative knowledge influences its accessibility in cognitive tasks.
This report presents the results of incorporating constructivist methods, including concept maps, into an undergraduate structural geology curriculum. A concept map is a visual representation of concepts and their relationship to each other in a body of knowledge. They show the hierarchy of these concepts and emphasize the links between them. The overall goal of this project was to encourage students to adopt a deep/holistic approach to learning in order to better understand the concepts of structural geology. The authors sought to determine whether teaching methods became more overtly constructivist, whether there was a change in the order of presentation of topics, and whether the order of presentation normally followed by textbooks was the same as the order determined using concept maps.

Concept mapping is a method that creates a visual representation that illustrates the thoughts, ideas, or planned actions that arise from a group of stakeholders on a particular issue. Social network analysis is a method that likewise creates a visual representation of data; a network map typically represents people and the connections, or lack thereof, between these people regarding a particular issue. While the goals of these two methods differ, the underlying data structures are similar; a network of relationships between data elements. Social network analysis is explored here as a supplement to concept mapping. A secondary analysis of a concept map to define to leadership needs was conducted using social network analysis. The methods and the implications for supplementing the analysis of concept maps and debriefing results with stakeholders are discussed. PMID:22705980

Full Text Available The present study investigated the influence of concept mapping as a post-reading strategy on EFL learners' critical thinking ability. The study utilized a pretest – posttest control and experimental group design. To do so, thirty six EFL learners at upper intermediate and advanced levels were randomly assigned to experimental (n=18 and control (n=18 groups. The results of pretest indicated that the participants of the two groups were homogenous with regard to their proficiency level and critical thinking ability. The experimental group was instructed to construct concept maps after reading each text and formulated the required post-reading activities on the basis of the constructed maps. Critical thinking skill was assessed via the "Watson-Glaser Critical Thinking Appraisal" (CTA. The results of posttest indicated that concept mapping has a positive and significant influence on learners' critical thinking ability. The discussion and conclusions of the research are further presented with reference to the finding.

The purpose of the research was to establish the impact of the application of a concept map in chemistry lessons on the effective solving of tasks with organic reactions content. In the first phase of the research, a concept map was produced representing the reactions of hydrocarbons, organic halogenated compounds and organic oxygen compounds, and in the second phase the produced concept map was introduced in lessons. Its impact was tested on a sample consisting of 186 students (average age of 17.8 years), who were divided into a control group (88 students) and an experimental group (98 students). Prior to the experiment, the two groups were equalised in terms of their level of development of formal logical thinking and their average grade in chemistry. A knowledge test, consisting of five problem tasks comprising multiple parts, was used as a quantitative instrument for measuring the impact of the applied concept map. The content of the knowledge test was selected on the basis of the chemistry lesson plan (reactions of organic oxygen compounds) for general upper secondary schools (in Slovenian: gimnazije). An analysis of the task solving showed statistically significant differences in the responses of the experimental group members and the control group members (experimental group M = 15.9; SD = 6.33; control group M = 13.6; SD = 7.93; p = 0.03). The produced concept map contributed to the more effective interrelation of concepts and, consequently, to more effective problem task solving. PMID:26085431

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

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.

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

What I attempt to present here may be understood as an attempt to comply with the appeal made by Roland Barthes in "Semiology and Urbanism": to multiply not only the functional studies of the city, but also, and not the least, the readings of the city. I will pursue the hypothesis that studies of urban sound may not only be operational in leading to better sonic environments, but rather such studies could be a useful resource for planners, architects, designers, politicians etc. whishing to analyze the social dynamics of urban life. This article takes the case of Gang i København, a strategic project from the Copenhagen Munincipelity initiated in 2006, as a starting point to discuss the politics of urban sound. It points out an important challenge for the methodology of urban sonic environments: namely that sound as a senso-motoric register may be poorly evaluated through concepts of noise and harmonics, taken to express disturbance and well-being respectively. A cultural theory of urban sonic environments would focus on the sociality of sound and investigate the ways in which people interact and make meaning through sound. Arguing for the relevance of a method to register and describe auditory practices as a kind of social interaction – a method that may supplement the engineer’s quantitative sound measurements and the landscape architect’s qualitative descriptors this article outlines a few approaches to a theory of acoustic territoriality and suggests alternative ways of mapping, analyzing and planning urban sonic environments.

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.

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.

Public appreciation and basic understanding of the role the ocean plays in the global environment has become more important as the urgency to make decisions on complex environmental issues has increased. Because communicating science to the public is often challenging for scientists, they can benefit from employing methods such as concept mapping, which "deconstructs" science into discrete ideas and organizes them into graphical formats. Responding to recommendations by ocean science faculty ...

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

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 1980s. 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 × 10 km(2). 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. PMID:25013034

Recent advances in molecular genetic technology allow for detailed characterization of genetic variation and easy cost-efficient accumulation of such data, even for large human samples. One such advance that presents incredible opportunities for identifying associations between genetic polymorphisms and disease-related phenotypes is the ability to quickly type a large number of single-nucleotide polymorphisms (SNPs). Contributors to Group 10 of Genetic Analysis Workshop 14 explored the potential of SNP genotypes for the association mapping of disease-related genes in family-based studies. Using both real data involving alcoholism susceptibility, made available by the Collaborative Study on the Genetics of Alcoholism (COGA), and simulated data involving personality-disorder susceptibility, group members investigated specific methodological issues involved in association mapping, such as multiple testing, single SNPs vs. combinations and haplotypes, and the effect of linkage disequilibrium on SNP-based linkage; evaluated existing methodologies for association mapping using SNPs, short-tandem repeats (STRs), or a combination of the two; and introduced new or modified association-mapping methods, including a gamma random effects (GRE) model and the quantitative trait linkage disequilibrium (QTLD) test. These papers are unified by the application of association-based methods to analyze SNPs, microsatellite markers, or both, to identify chromosomal regions harboring genes that contribute to quantitative endophenotype variation, and thus to disease risk. Their diversity attests to the breadth and flexibility of association-mapping approaches to the genetics of complex disease. PMID:16342177

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

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.

The following five steps determine the delivery and the sequence of the study: 1 A TOEFL test (writing section as the pretest, 2 self-efficacy questionnaire, 3 8 sessions of instruction on concept map construction with experimental group, 4 integration of concept mapping as a pre-writing strategy in experimental group, and 5 post-test of writing and self-efficacy questionnaire with both groups. Firstly, the writing Proficiency Test along with self-efficacy questionnaire was given to 180 learners. Based on the results of TOEFL writing test and self-efficacy questionnaire, 60 intermediate homogeneous participants were selected and randomly assigned to two groups of control and experimental. In the course of 22-sessions, during regular class time 15 minutes were devoted to concept mapping. Each session the participants of both groups were given a writing task besides their course book writing section. The students in the experimental group were engaged in concept map construction after writing each task and were organized their pre-writing activities such as discussion, doing exercises, and reflective practices according to their constructed maps. A post-test of writing and an efficacy questionnaire were administered to all the participants and the pair sample t- test, and independent sample t-test were used to answer the study questions. The results showed that concept mapping had a significant effect on self- efficacy and expository writing accuracy.

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
Full Text Available One of important aspects of strategic management is the instrumental aspect included in a rich set of methods and techniques used at particular stages of strategic management process. The object of interest in this study is the development of views and the implementation of strategy as an element of strategic management and instruments in the form of methods and techniques. The commonly used method in strategy implementation and measuring progress is Balanced Scorecard (BSC. The method was created as a result of implementing the project “Measuring performance in the Organization of the future” of 1990, completed by a team under the supervision of David Norton (Kaplan, Norton 2002. The developed method was used first of all to evaluate performance by decomposition of a strategy into four perspectives and identification of measures of achievement. In the middle of 1990s the method was improved by enriching it, first of all, with a strategy map, in which the process of transition of intangible assets into tangible financial effects is reflected (Kaplan, Norton 2001. Strategy map enables illustration of cause and effect relationship between processes in all four perspectives and performance indicators at the level of organization. The purpose of the study being prepared is to present methodical conditions of using strategy maps in the strategy implementation process in organizations of different nature.

Objective. To describe the utility of concept mapping in a cardiovascular therapeutics course within a large classroom setting. Design. Students enrolled in a cardiovascular care therapeutics course completed concept maps for each major chronic cardiovascular condition. A grading rubric was used to facilitate peer-assessment of the concept map. Assessment. Students were administered a survey at the end of the course assessing their perceptions on the usefulness of the concept maps during the course and also during APPEs to assess utility beyond the course. Question item analyses were conducted on cumulative final examinations comparing student performance on concept-mapped topics compared to nonconcept-mapped topics. Conclusion. Concept maps help to facilitate meaningful learning within the course and the majority of students utilized them beyond the course. PMID:26056408

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.

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.

Concept mapping has become a popular learning tool. However, the processes underlying the task are poorly understood. In the present study, we examined the effect of creating a concept map on the processing of item-specific information. In 2 experiments, subjects learned categorized or ad hoc word lists by making pleasantness ratings, sorting words into categories, or creating a concept map. Memory was tested using a free recall test and a recognition memory test, which is considered to be especially sensitive to item-specific processing. Typically, tasks that promote item-specific processing enhance free recall of categorized lists, relative to category sorting. Concept mapping resulted in lower recall performance than both the pleasantness rating and category sorting condition for categorized words. Moreover, concept mapping resulted in lower recognition memory performance than the other 2 tasks. These results converge on the conclusion that creating a concept map disrupts the processing of item-specific information. PMID:25528090

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 AutÃ³noma 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.

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.

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

Abstract in english This paper makes explicit the results of the research project entitled how does mind and concept mapping strategy stimulate visual-spatial intelligence development among university students?, which was developed in the framework of both Gardner's theory of Multiple intelligences and the work by nova [...] k and Buzán around concept and mind maps. Results of research evidence that using this strategy makes up a tool leveraging visualspatial intelligence, since it stimulates: the creation of images arranged so as to explain an idea; the development of visual memory to execute and recreate earlier perceptions; the improvement of artistic and aesthetic sense; a practice to control fine motor movement; a practice of visual art, since there is object, figure, color, proportion and perspective retention, among other central abilities characterising this intelligence.

Despite obvious limitations as a proxy for site amplification, the use of time-averaged shear-wave velocity over the top 30 m (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. An additional advantage of Vs30 measurements (rather than more complex frequency-dependent, site amplification characterizations), and perhaps one of the reasons it is so widely in use, is the ability to extrapolate Vs30 point observations to maps and thus to apply the limited existing data to important regional hazard mapping applications. It is this advantage upon which we expand in this study. Two common existing Vs30 mapping approaches, geology- and topographic-slope-based proxies, are attractive in that both are available in many areas of the world and can thus be applied over wide regions. Yet, although derived from or aimed to be consistent with observed Vs30 values, a limiting aspect of these current state-of-the-art Vs30 mapping strategies is that these approaches fail to directly incorporate the Vs30 observations back into the map. Likewise, predictive models typically fail to accommodate significant new Vs30 data as they become available even if they show trends that deviate from the default trend models. As such, we have developed a strategy for developing Vs30 maps that uses a hierarchical approach, where the baseline model is derived from topographic slope because it is available globally, yet 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 interaction (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 strategy takes 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. Finally, we generalize this approach, outlining an overall "recipe" for hierarchical Vs30 map-making, dependent on the available data sources in a particular region. This new mapping strategy provides motivation for collecting Vs30 data at any spatial scale, because any new data can be used explicitly in refining Vs30 maps: geostatistically, both local point constraints and regional trend removal are extremely beneficial.

Full Text Available Introduction Concept mapping is a structured conceptualization process that provides a visual representation of relationships among ideas. Concept mapping was used to develop a logic model for the Centers for Disease Control and Prevention’s Prevention Research Centers Program, which has a large and diverse group of stakeholders throughout the United States. No published studies have used concept mapping to develop a logic model for a national program. Methods Two logic models were constructed using the data from the concept mapping process and program documents: one for the national level and one for the local level. Concept mapping involved three phases: 1 developing questions to generate ideas about the program’s purpose and function, 2 gathering input from 145 national stakeholders and 135 local stakeholders and sorting ideas into themes, and 3 using multivariate statistical analyses to generate concept maps. Logic models were refined using feedback received from stakeholders at regional meetings and conferences and from a structured feedback tool. Results The national concept map consisted of 9 clusters with 88 statements; the local concept map consisted of 11 clusters with 75 statements. Clusters were categorized into three logic model components: inputs, activities, and outcomes. Based on feedback, two draft logic models were combined and finalized into one for the Prevention Research Centers Program. Conclusion Concept mapping provides a valuable data source, establishes a common view of a program, and identifies inputs, activities, and outcomes in a logic model. Our concept mapping process resulted in a logic model that is meaningful for stakeholders, incorporates input from the program’s partners, and establishes important program expectations. Our methods may be beneficial for other programs that are developing logic models for evaluation planning.

Full Text Available Introduction: Considering the importance, complexity, and problems in nursing education, using efficient and new methods in nursing education seems to be necessary. One of the most important of these methods which has received attention in recent years is the use of concept maps. Therefore, the aim of this study was systematic review of studies conducted in this field. Methods: Required information for this systematic review study was collected using keywords of concept map, learning, retention, nursing education, critical thinking skill, and Iran and their English synonyms in data bases of Iranmedex, Magiran, Science Direct, PubMed, Google scholar, Medlib, and SID. No time limitation was considered for searching articles. Articles published in Farsi and English have been searched. Results: Results show that concept maps have a significant effect on improving critical thinking of learners. Compared to other educational methods such as lectures; using concept maps show higher efficiency in deep and meaningful learning. Besides, concept maps have a significant effect on learning (relationship of theory and practice, improvement of clinical experiences, organizing concepts, and self-regulation. Conclusion: According to the importance of nursing education and its available problems on one hand, and the use and applicability of concept maps on the other hand (as well as ignorance about this educational method, it seems necessary to plan for the development of using concept maps in educational nursing.

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.

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.

Marsupials are especially valuable for comparative genomic studies of mammals. Two distantly related model marsupials have been sequenced: the South American opossum (Monodelphis domestica) and the tammar wallaby (Macropus eugenii), which last shared a common ancestor about 70 Mya. The six-fold opossum genome sequence has been assembled and assigned to chromosomes with the help of a cytogenetic map. A good cytogenetic map will be even more essential for assembly and anchoring of the two-fold wallaby genome. As a start to generating a physical map of gene locations on wallaby chromosomes, we focused on two chromosomes sharing homology with the human X, wallaby chromosomes X and 5. We devised an efficient strategy for mapping large conserved synteny blocks in non-model mammals, and applied this to generate dense maps of the X and 'neo-X' regions and to determine the arrangement of large conserved synteny blocks on chromosome 5. Comparisons between the wallaby and opossum chromosome maps revealed many rearrangements, highlighting the need for comparative gene mapping between South American and Australian marsupials. Frequent rearrangement of the X, along with the absence of a marsupial XIST gene, suggests that inactivation of the marsupial X chromosome does not depend on a whole-chromosome repression by a control locus.

Radiotherapy is fractionized to increase the therapeutic ratio. Fractionation in conventional treatment is determined as part of the prescription, and a fixed fraction size is used for the whole course of treatment. Due to patients' day-to-day variations on the relative distance between the tumor and the organs at risk (OAR), a better therapeutic ratio may be attained by using an adaptive fraction size. Intuitively, we want to use a larger fraction size when OAR and the tumor are far apart and a smaller fraction size when OAR and the tumor are close to each other. The concept and strategies of adaptive fractionation therapy (AFT) are introduced in this paper. AFT is an on-line adaptive technique that utilizes the variations of internal structures to get optimal OAR sparing. Changes of internal structures are classified as different configurations according to their feasibility to the radiation delivery. A priori knowledge is used to describe the probability distribution of these configurations. On-line processes include identifying the configuration via daily image guidance and optimizing the current fraction size. The optimization is modeled as a dynamic linear programming problem so that at the end of the treatment course, the tumor receives the same planned dose while OAR receives less dose than the regular fractionation delivery. Extensive simulations, which include thousands of treatment courses with each course consisting of 40 fractions, are used to test the efficiency and robustness of the presented technique. The gains of OAR sparing depend on the variations on configurations and the bounds of the fraction size. The larger the variations and the looser the bounds are, the larger the gains will be. Compared to the conventional fractionation technique with 2 Gy/fraction in 40 fractions, for a 20% variation on tumor-OAR configurations and [1 Gy, 3 Gy] fraction size bounds, the cumulative OAR dose with adaptive fractionation is 3-8 Gy, or 7-20% less than that of the regular fractionation, while maintaining the same cumulative tumor dose as prescribed.

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

A concept map provides a ?snap shot? of a student?s understanding that is frozen in time by drawing it out on paper or on a computer screen. However, to represent the dynamic state of student learning, concept maps either need to emphasise dynamism (through the phrases that are chosen to act as links within the propositions that form the map), or need to be viewed as a single perspective on a more complex situation that can only be fully appreciated by considering movement between knowledge s...

Geomorphological mapping plays an essential role in understanding Earth surface processes, geochronology, natural resources, natural hazards and landscape evolution. It involves the partitioning of the terrain into conceptual spatial entities based upon criteria that include morphology (form), genetics (process), composition and structure, chronology, environmental system associations (land cover, soils, ecology), as well as spatial topological relationships of surface features (landforms). Historically, the power of human visualization was primarily relied upon for analysis, introducing subjectivity and biases with respect to selection of criteria for terrain segmentation and placement of boundaries. This paper reviews new spatio-temporal data and geocomputational approaches that now permit Earth scientists to go far beyond traditional mapping, permitting quantitative characterization of landscape morphology and the integration of varied landscape thematic information. Numerous conceptual, theoretical, and information-technology issues are at the heart of digital geomorphological mapping (DGM), and scientific progress has not kept pace with new and rapidly evolving geospatial technologies. Consequently, new capabilities exist but numerous issues have not been adequately addressed. Therefore, this paper discusses conceptual foundations and illustrates how geomorphometry and mapping approaches can be used to produce geomorphological information related to the land surface and landforms, process rates, process-form relationships, and geomorphic systems.

Physiology is often considered a challenging course for students. It is up to teachers to structure courses and create learning opportunities that will increase the chance of student success. In an undergraduate exercise physiology course, concept maps are assigned to help students actively process and organize information into manageable and meaningful chunks and to teach them to recognize the patterns and regularities of physiology. Students are first introduced to concept mapping with a commonly relatable nonphysiology concept and are then assigned a series of maps that become more and more complex. Students map the acute response to a drop in blood pressure, the causes of the acute increase in stroke volume during cardiorespiratory exercise, and the factors contributing to an increase in maximal O2 consumption with cardiorespiratory endurance training. In the process, students draw the integrative nature of physiology, identify causal relationships, and learn about general models and core principles of physiology.

Full Text Available Teachers are always looking for innovative ways to help students improve their reading comprehension. One popular method is the use of graphic organizers such as concept maps. 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 Because the volume of web resources (web pages, images, music, video, etc. continues to increase exponentially, enabling reuse and sharing of creative knowledge in engineering domain becomes our driving force to develop the knowledge map navigation. Map navigation is a way of organizing the world's information geographically. Knowledge maps are used to visualize a set of related information. To solve problems of knowledge sharing and knowledge reusing in engineering domain, this study proposed a knowledge map navigation which is based on functional ontology and concept maps. At last, a case study on contest robot is applied to demonstrate the proposed model can promote the information searching more efficiently. In order to share the functional knowledge model anywhere on the Internet, we use CmapTools which allow users to construct, navigate, share and criticize knowledge models represented as concept to implement that. It shows some benefits from functional ontology-based applications in engineering knowledge management domain.

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.

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

Full Text Available The PISA 2000 study found large differences between countries in terms of quality of learning. In somecountries, students prefer rote learning to meaningful learning. However, such memorisation of thematerial does not lead to recallable and usable knowledge in the long run. Ausubel's (1968 wellknowntheory serves as a basis for several techniques of meaningful learning, including conceptmapping, which emphasises the visual organization of comprehended information. The present studyreports the results of an experiment using concept mapping for deepening students’ understandingof teaching materials. It focuses on definitions frequently used in science and Hungarian grammarlessons. Results indicate that concept mapping training programmes can improve participants’achievement. 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.

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.

Heard through the ears of the Canadian composer and music teacher R. Murray Schafer the ideal auditory community had the shape of a village. Schafer’s work with the World Soundscape Project in the 70s represent an attempt to interpret contemporary environments through musical and auditory parameters highlighting harmonious and balanced qualities while criticizing the noisy and cacophonous qualities of modern urban settings. This paper present a reaffirmation of Schafer’s central methodological claim: that environments can be analyzed through their sound, but offers considerations on the role of sound as an active component in shaping urban environments. As urban conditions spreads globally, new scales, shapes and forms of communities appear and call for new distinctions and models in the study and representation of sonic environments. Particularly so, since urban environments are increasingly musicalized through electro acoustic equipment installed in shops, shopping streets, transit areas etc. Urban noiseno longer acts only as disturbance, but also structure and shape the places and spaces in which urban life enfold. Based on research done in Japanese shopping streets and in Copenhagen the paper presents some terminologies for mapping urban environments through its sonic configuration. Such probing into the practices of acoustic territorialisation may direct attention to some of the conflicting and disharmonious interests defining public inclusive domains. The paper investigates the concept of urban noise not only as a disturbing and potentially unhealthy influence, but also as a condition for interaction, creativity and inclusiveness and makes three propositions for a theory of urban sonic environments.

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

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.

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.

There is now evidence to suggest that the degree to which hypertext or web-based instructional systems facilitate recall of information appears to be contingent on an individual's cognitive or information processing style. Concept maps also reflect the way in which individuals process information and therefore it is possible that cognitive style…

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.

The excitation map concept introduced by Solbrig to discuss threshold effects in very low energy electron diffraction (VLEED) is reinvestigated. In detail the relevance of such excitation maps (|det (1 - M-+R+-)| where M-+ is the reflection matrix of the atomic planes and R+- is the internal reflection matrix of the surface barrier) for characterizing surface resonances in VLEED is examined. It is shown that, in most cases, the use of this concept leads to an overestimate of the resonance contribution in VLEED spectra. The excitation map concept is replaced by a new relevant one. This result is exemplified by reinvestigating the region of Solbrig's excitation map on Ni(001) corresponding to the normal incidence, just below the emergence of the first four diffracted beams (10), (01), (1-bar0), and (01-bar). Even in this case, in favour of the resonance interpretation according to Solbrig's analysis, it is shown that the picture of the waveguide located at the surface, channelling the pre-emergent waves, falls down. This conclusion is strengthened by an analysis of the reflection amplitude matrix of the crystal based upon a second-order expansion in which the actual role played by resonances can be easily examined. In the case of Ni(001), threshold effects are only due to a simple interference process. (author)

Full Text Available This text presents the origin of the concept map tool and some of the early history in the development of this tool. Some of the ideas from Ausubel’s (1963; 1968 assimilation theory of cognitive learning that served as a foundation for concept mapping are presented, including the important role that assimilating new concepts and propositions into a learner’s existing cognitive framework plays in meaning making. Epistemological foundations are also presented including the idea that creative production of new knowledge can be seen as a very high level of meaningful learning, and concept mapping can facilitate the process. The wide range of tools available in free CmapTools software and some applications are illustrated, including application for facilitating meaningful learning, better curriculum development, capturing and archiving tacit and explicit expert knowledge, and enhancing creative production. Using CmapTools, WWW resources, and other digital resources provide for a powerful New Model for Education leading to the creation of individual knowledge portfolios that can document significant learning and serve as a foundation for future related learning. CmapTools also provides extensive support for collaboration, publishing and sharing of knowledge models.
Full Text Available This paper describes the needs analysis of tool for connecting people in a Learning Network using Group Concept Mapping method. We conducted an empirical study to identify the most relevant features of such a tool. There were 11 experts from 7 different countries with technical and non-technical background who participated in the study. Each of the participants were invited by email and given a brief description about the scenario for the need of a tool in an online Learning Network to find people for help (social support system. This tool can be developed on mobile devices to search for peer learners. The participants generated 153 unique ideas about the need for social support system in Learning Network. These ideas were sorted and rated, and further analysis with Concept Mapping produced ten relevant clusters of interest. These clusters (concepts suggest the features which are relevant for a tool that would support learners in connecting with others in a Learning Network. The concept mapping methodology described in this paper has also been applied in other projects; one of them is about the “investigation of pedagogic areas in which mobile learning is an appropriate solution”. We intend to publish the work in the future publication.
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.

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.

Microcomputers and appropriate software have the potential to help students learn. They can also serve as appropriate media for investigating how students learn. In this article we describe a research strategy examining learning and behavior when students interacted with microcomputers and software. Results from two preliminary studies illustrate the strategy.A major feature of the strategy included recording students interacting with microcomputer software interfaced with a VCR. The VCR recorded the video output from a microcomputer and students' verbal commentary via microphone input. This technique allowed students' comments about their observations, perceptions, predictions, explanations, and decisions to be recorded simultaneously with their computer input and the display on the microcomputer monitor.The research strategy described can provide important information about cognitive and affective behaviors of students engaged in using instructional software. Research studies utilizing this strategy can enhance our understanding of how students develop and employ important concepts and scientific relationships, how students develop problem-solving skills and solve problems, and how they interact with instructional software. Results of such studies have important implications for teaching and for the design of instructional software.

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

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.

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

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

Full Text Available The personal boundaries that an individual experiences can be figured out based on the relationship between dwelling, working and socializing as the three main axes of everyday life. The boundaries that are illustrated as the concept “personal reach” in this study, are being formulated in the influence of several parameters such as urbanization, transportation and housing. Focusing on transportation as one of the most distinctive parameters, the transformation of the transportation systems and vehicles in time are being investigated through the case study of Istanbul in the scope of this research. According to this context the transformative effects of transportation on the concept is being explored and the change of an individual’s personal reach patterns are surveyed. In order to clarify the alternation mentioned, urban scale maps explaining the progress of the transportation systems are prepared to convey this progress visually. In the process of Istanbul’s urbanization in time, early years of the republican era emerge as a distinguishing period in that transportation and the city co-evolve together. Accordingly, focusing on the first years of the republican era and the present days of Istanbul in particular, the survey presents a reading on the two eras’ transportation opportunities regarding the personal reach concept through the maps configurated.

Paradoxically, individuals with food insecurity have been observed to have higher rates of obesity compared with their counterparts with food security. The factors influencing food purchasing behaviors in households with food security vs food insecurity are poorly understood. Using the mixed methods approach of concept mapping, we examined the perceptions and preferences driving the food purchasing behaviors of households with food security vs food insecurity. Twenty-six men and women with food security and 41 men and women with food insecurity from four neighborhoods in Boston, MA, completed the concept mapping process during 2010. Prevalence of overweight and obesity was greater among participants with food insecurity (80.5%) compared with those with food security (61.5%). Participants identified 163 unique factors that influenced their food purchasing behavior. Using multivariate analyses, these factors were grouped into eight unique concepts or clusters that reflected their perceptions of factors hindering healthy eating. Average cluster ratings were similar between participants with food security and food insecurity, suggesting that similar food purchasing behaviors are employed and are perceived similarly in how they hinder or promote healthy eating. The use of emergency food assistance programs may play a role in minimizing the burden of food insecurity while providing access to foods with varying degrees of nutritional quality that may be associated with increased risk of overweight and obesity observed in individuals and households with food insecurity.

Last year, the Center for Mars Exploration (CMEX) at NASA Ames Research Center issued its 'Return to Mars 1997' educational CD ROM. This CD, produced under the guidance of Dr. Geoffrey Briggs, summarized the on-going exploration of Mars and consisted of six sub-topics: (1) Life on Mars?; (2) Mars, The Red Planet; (3) Human Exploration; (4) Robotic Missions; (5) Atlas and Image Processing; and (6) Links for Teachers. Although the CD contained a wealth of information, its format does not allow ready retrieval of information on a specific topic or concept. CMEX is working with Dr. Alberto Canas and colleagues at the University of West Florida to improve the CD's user interface through the use of concept mapping.

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

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

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.

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.

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.

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.
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)

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

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.

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.

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.

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

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
Full Text Available Research on anxiety in a foreign language-learning context is well-documented; however, few studies have directly focused on anxiety occurring within writing contexts despite the fact that writing anxiety is known to affect students’ learning. The present study examined the effectiveness of concept mapping considering students’ writing anxiety. Participants completed writing anxiety scales and were randomly assigned to three groups before completing a writing task: concept mapping, idea listing, or an unrelated task. Results indicated that, especially for students with low trait-level writing anxiety, concept mapping positively influenced the quality of writing content. Teaching implications will be discussed in the light of the results of this study.

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.

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.
Full Text Available The combination of Data warehousing and data analysis techniques such as OLAP (Online Analytic Processing and data mining through the Hadoop framework is an innovative way to treat large volumes of data. However, this way poses serious scheduling and combining tasks issues that bring more challenges.In this paper, we propose strategies to answer these questions, namely parallel OLAM (Online Analytic Mining MapReduce Operators and a Reactive Scheduling Policy. OLAM MapReduce Operators divide jobs into two parts, the first includes all the operators that are used to create an OLAM CUBE and the second includes those who exploit the cube by data mining algorithms. The proposed policy coordinates the workflow generated by these operators, relying on model-based events. Our simulation experience shows that our strategy has a cumulative force that it reduces the execution time of the entire cluster at each request.

The Aerial Regional-scale Environmental Survey (ARES) is a Mars exploration mission concept designed to send an airplane to fly through the lower atmosphere of Mars, with the goal of taking scientific measurements of the atmosphere, surface, and subsurface phenomenon. ARES was first proposed to the Mars Scout program in December 2002 for a 2007 launch opportunity and was selected to proceed with a Phase A study, step-2 proposal which was submitted in May 2003. ARES was not selected for the Scout mission, but efforts continued on risk reduction of the atmospheric flight system in preparation for the next Mars Scout opportunity in 2006. The ARES concept was again proposed in July 2006 to the Mars Scout program but was not selected to proceed into Phase A. This document describes the Planetary Protection strategy that was developed in ARES Pre Phase-A activities to help identify, early in the design process, certain hardware, assemblies, and/or subsystems that will require unique design considerations based on constraints imposed by Planetary Protection requirements. Had ARES been selected as an exploration project, information in this document would make up the ARES Project Planetary Protection Plan.

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

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...

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.
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)

Results of an assessment of two programs, NASA SEI and the National Science Foundation's U.S. Antarctic Program (USAP) are presented. The assessment was aimed at determining the elements of USAP's operations which are relevant to living and working on the moon and Mars and at identifying operational concepts, procedures, and techniques which might be considered by NASA as it formulates the SEI concept. The assessment shows strong similarities in goals, related operational functions and accommodations, and fundamental strategies and policies for mission execution. Besides, both programs share logistical and operational constraints. There are differences in concepts for execution because of the unique aspects of accessing, living, and working in these environments.

A growing body of literature in biodiversity conservation and forestry has developed around the risks and benefits of the Assisted Migration (AM) of species, including recommendations for planning and management. However, despite years of academic debate, general consensus has yet to be reached between the proponents and the opponents of AM as a policy option. We hypothesize that the continued impasse arises out of fundamentally conflicting value judgments. Using a concept mapping technique, we analyzed reasons for and against AM, including the use of scientific evidence and the nature of the values and ethical norms that shape the modes of reasoning in the debate. Our results indicate the presence of a diversity of ethical arguments in addition to the standard precautionary argument and pragmatic reasoning. We further discovered that different kinds of scientific arguments are used by proponents versus opponents of AM: the former rely mostly on detailed biological and ecological facts about species most-at-risk under climate change, while the latter focus on broader ecological theories. Our analysis suggests little dispute over the scientific foundations of the debate. Instead, we suggest that the main barrier to consensus is the advocacy of fundamental values, which are a matter of personal choice, and thus not likely to be changed. One way out of this impasse is a pragmatic mode of reasoning, which eschews the debate on fundamental values and evaluates the means and ends of AM in a case-by-case approach.

The NASA Ames' Center for Mars Exploration (CMEX) serves to coordinate Mars programmatic research at ARC in the sciences, in information technology and in aero-assist and other technologies. Most recently, CMEX has been working with the Institute for Human and Machine Cognition at the University of West Florida to develop a new kind of web browser based on the application of concept maps. These Cmaps, which are demonstrably effective in science teaching, can be used to provide a new kind of information navigation tool that can make web or CD based information more meaningful and more easily navigable. CMEX expects that its 1999 CD-ROM will have this new user interface. CMEX is also engaged with the Mars Surveyor Project Office at JPL in developing an Internet-based source of materials to support the process of selecting landing sites for the next series of Mars landers. This activity -- identifying the most promising sites from which to return samples relevant to the search for evidence of life -- is one that is expected to engage the general public as well as the science community. To make the landing site data easily accessible and meaningful to the public, CMEX is planning to use the IHMC Cmap browser as its user interface.

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.

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.

Climate change is a complex environmental problem that can be used to examine students' understanding, gained through classroom communication, of climate change and its interactions. The present study examines a series of four science sessions given to a group of primary school student teachers (n = 20). This includes analysis of the communication styles used and the students' pre- and post-conceptualisation of climate change based on results obtained via essay writing and drawings. The essays and drawings concerned the students' unprompted pre- and post-conceptions about climate change, collected before and after each of the four inquiry-based science sessions (in physics, chemistry, biology and geography). Concept mapping was used in the analysis of the students' responses. The communication used in the four sessions was analysed with a communicative approach in order to find out the discussion about climate change between teacher and students. The analyses indicated that the students did not have the knowledge or the courage to participate in discussion, but post-conceptualisation map showed that students' thinking had become more coherent after the four sessions. Given the results of the present study, proposals for using concepts maps and/or communication analysis in studying students' conceptions are presented.
Análise do conhecimento e das concepções sobre saúde oral de alunos de odontologia: avaliação por meio de mapas conceituais Analysis of dental students' knowledge and concepts in oral health: evaluation by concept maps
Full Text Available O objetivo inicial deste trabalho foi apreender a estrutura cognitiva de alunos do último ano (sétimo período do curso de graduação em odontologia da UFRJ em relação à temática do esmalte. Essa temática é de fundamental importância para a compreensão da saúde oral, na medida em que oferece conceitos científicos importantes e fundamentais para o exercício da prática clínica e preventiva, bem como por ser objeto de estudo em várias disciplinas ao longo do curso de Odontologia. Para a análise da estrutura cognitiva, utilizou-se a estratégia de mapas conceituais proposta por Novak e fundamentou-se na teoria da Aprendizagem Significativa, de Ausubel. A análise dos mapas elaborados pelos estudantes possibilitou um estudo não só sobre a estrutura cognitiva e as concepções sobre saúde oral dos alunos, como também permitiu um diagnóstico do conhecimento em diversos aspectos relevantes à formação científica e profissional, apontando para a necessidade de se repensar o processo ensino-aprendizagem nos cursos de Odontologia.This study sought to analyze senior dental students' cognitive structure concerning the topic of "enamel", which is fundamentally important for understanding oral health, since it offers basic scientific concepts for clinical and preventive practices and is the main subject of several courses during dentistry training. The strategy used to analyze students' cognitive structures was Novak's Concept Maps, based on Ausubel's Meaningful Learning theory. Analysis of students' maps allowed for a study of students' cognitive structure and concepts concerning oral health. It also fostered a diagnosis of students' knowledge in several important aspects of scientific and professional training. The results highlighted the need for rethinking the teaching/ learning process in dentistry training.

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.

For the sensitive and convenient detection of pesticides, several sensing methods and materials have been widely explored. However, it is still a challenge to obtain sensitive, simple detection techniques for pesticides. Here, the simple and sensitive Time-resolved SERS mapping (T-SERS) and Spatial-resolved SERS mapping (S-SERS) are presented for detection of pesticides by using Au@Ag NPs as SERS substrate. The Time-resolved SERS mapping (T-SERS) is based on state translation nanoparticles from the wet state to the dry state to realize SERS measurements. During the SERS measurement, adhesive force drives the particles closer together and then average interparticle gap becomes smaller. Following, air then begins to intersperse into the liquid network and the particles are held together by adhesive forces at the solid-liquid-air interface. In the late stage of water evaporation, all particles are uniformly distributed. Thus, so called hotspots matrix that can hold hotspots between every two adjacent particles in efficient space with minimal polydispersity of particle size are achieved, accompanying the red-shift of surface plasmon peak and appearance of an optimal SPR resonated sharply with excitation wavelength. Here, we found that the T-SERS method exhibits the detection limits of 1-2 orders of magnitude higher than that of S-SERS. On the other hand, the T-SERS is very simple method with high detection sensitivity, better reproducibility (RSD=10.8%) and is beneficial to construction of a calibration curve in comparison with that of Spatial-resolved SERS mapping (S-SERS). Most importantly, as a result of its remarkable sensitivity, T-SERS mapping strategies have been applied to detection of several pesticides and the detect limit can down to 1nM for paraoxon, 0.5nM for sumithion. In short, T-SERS mapping measurement promises to open a market for SERS practical detection with prominent advantages. PMID:25966372

The field of sonification has progressed greatly over the past twenty years and currently constitutes an established area of research. This article aims at exploiting and organizing the knowledge accumulated in previous experimental studies to build a foundation for future sonification works. A systematic review of these studies may reveal trends in sonification design, and therefore support the development of design guidelines. To this end, we have reviewed and analyzed 179 scientific publications related to sonification of physical quantities. Using a bottom-up approach, we set up a list of conceptual dimensions belonging to both physical and auditory domains. Mappings used in the reviewed works were identified, forming a database of 495 entries. Frequency of use was analyzed among these conceptual dimensions as well as higher-level categories. Results confirm two hypotheses formulated in a preliminary study: pitch is by far the most used auditory dimension in sonification applications, and spatial auditory dimensions are almost exclusively used to sonify kinematic quantities. To detect successful as well as unsuccessful sonification strategies, assessment of mapping efficiency conducted in the reviewed works was considered. Results show that a proper evaluation of sonification mappings is performed only in a marginal proportion of publications. Additional aspects of the publication database were investigated: historical distribution of sonification works is presented, projects are classified according to their primary function, and the sonic material used in the auditory display is discussed. Finally, a mapping-based approach for characterizing sonification is proposed. PMID:24358192
Full Text Available The document retrieval is one of the fast growing and complex research area in the field of information retrieval. Concept-based information retrieval is more beneficial than keyword-based access. The most important advantage is the ability to make use of semantic relationships among concepts in finding relevant documents. Removal of irrelevant documents by identifying conceptual mismatches is another benefit. The linguistic representation of concepts is words and phrases. These concepts are mental structures. The inherent conciseness of natural language can make words represent multiple concepts. Different words can represent the same or similar concepts. We present a novel method of concept mining methodology, which provides an efficient way of document retrieval. The performance of this proposed retrieval system was analyzed by the existing methods for different medical documents. The proposed retrieval system shows that the documents are retrieved effectively based on concepts and the system performs with higher accuracy value.

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.

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)

The purpose of this study was to analyze the relationship of concept mapping to science problem solving in sixth grade elementary school children. The study proposes to determine whether the students' ability to perform higher cognitive processes was a predictor of students' performance in solving problems in science and whether gender and socioeconomic status are related to performance in solving problems. Two groups participated in the study. Both groups were given a pre-test of higher cognitive ability--the Ross Test of Higher Cognitive Ability. One group received instruction on a science unit of study in concept mapping format and the other group received instruction in traditional format. The instruction lasted approximately 4 weeks. Both groups were given a problem-solving post-test. A comparison of post-test means was done using Analysis of Covariance (ANCOVA) as the statistical procedure with scores on the test of higher cognitive ability as the covariate. Also, Multiple Regression was performed to analyze the influence of participants' gender and socioeconomic status on their performance in solving problems. Results from the analysis of covariance showed that the group receiving instruction in the concept mapping format performed significantly better than the group receiving instruction in traditional format. Also the Ross Test of Higher Cognitive Processes emerged to be a predictor of performance on problem solving. There was no significant difference in the analysis of the performance of males and females. No pattern emerged regarding the influence of socioeconomic status on problem solving performance. In conclusion, the study showed that concept mapping improved problem solving in the classroom, and that gender and socioeconomic status are not predictors of student success in problem solving.

As a result, teaching with the concept maps was found to affect students’ academic success at significant level. Some suggestions were made in the light of outcomes.
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.

OECD countries recognized in the mid-1990s that transport trends were not sustainable and that existing policy frameworks seemed unlikely to be able to move society towards more sustainable transport systems. A new approach to transport policy was required that would be consistent with the broad definition of sustainable development. To this end, the project on Environmentally Sustainable Transport (EST) was initiated to give some precision to the concept of EST through the use of criteria that have environmental significance and can be quantified. A method known as 'backcasting' was used to develop policies and strategies for achieving a desired future state through targeted action. This paper summarizes the results of the project, which involved twelve OECD countries that undertook case studies at local, regional, national and international scales. The project concluded that some 40 per cent of the effort necessary to meet the EST criteria will come from technology and 60 per cent from demand-side management and a shift towards more sustainable transport modes. EST is attainable, but only if a broad range of instruments is deployed. These include regulations and standards, fiscal measures, changes in governance arrangements, and education, the provision of information, awareness raising, and attitude change, all assembled into coherent packages of instruments applied with careful consideration to phasing. Significant structural changes and adaptations will be required to realize EST. They will reduce social costs and provide net benefits for the environment and for quality of life in general. The required changes will provide major opportunities for new business, including integrated mobility services, freight logistics, and information technology. A key outcome of the project was a set of guidelines for moving towards EST.

Non-coding RNAs fold into precise base-pairing patterns to carry out critical roles in genetic regulation and protein synthesis, but determining RNA structure remains difficult. Here, we show that coupling systematic mutagenesis with high-throughput chemical mapping enables accurate base-pair inference of domains from ribosomal RNA, ribozymes and riboswitches. For a six-RNA benchmark that has challenged previous chemical/computational methods, this ‘mutate-and-map’ strategy gives secondary structures that are in agreement with crystallography (helix error rates, 2%), including a blind test on a double-glycine riboswitch. Through modelling of partially ordered states, the method enables the first test of an interdomain helix-swap hypothesis for ligand-binding cooperativity in a glycine riboswitch. Finally, the data report on tertiary contacts within non-coding RNAs, and coupling to the Rosetta/FARFAR algorithm gives nucleotide-resolution three-dimensional models (helix root-mean-squared deviation, 5.7 Å) of an adenine riboswitch. These results establish a promising two-dimensional chemical strategy for inferring the secondary and tertiary structures that underlie non-coding RNA behaviour.

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. Normality test of residuals was made, finding that the data behave normally resulting in a p-value of 58%. Also, we conducted surveys of e

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

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.

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.

The United Nations initially contracted with NASA to carry out investigations in three countries; but now as the result of rapidly increasing interest, ERTS imagery has been/is being used in 7 additional projects related to agriculture, forestry, land-use, soils, landforms and hydrology. Initially the ERTS frames were simply used to provide a synoptic view of a large area of a developing country as a basis to regional surveys. From this, interest has extended to using reconstituted false color imagery and latterly, in co-operation with Purdue University, the use of computer generated false color mosaics and computer generated large scale maps. As many developing countries are inadequately mapped and frequently rely on outdated maps, the ERTS imagery is considered to provide a very wide spectrum of valuable data. Thematic maps can be readily prepared at a scale of 1:250,000 using standard NASA imagery. These provide coverage of areas not previously mapped and provide supplementary information and enable existing maps to be up-dated. There is also increasing evidence that ERTS imagery is useful for temporal studies and for providing a new dimension in integrated surveys.

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

The Geological Survey of Austria is legally obligated by the INSPIRE directive to provide data that fall under this directive (geology, mineral resources and natural risk zones) to the European commission in a semantically harmonized and technically interoperable way. Until recently the focus was entirely on the publication of high quality printed cartographic products. These have a complex (carto-)graphic data-model, which allows visualizing several thematic aspects, such as lithology, stratigraphy, tectonics, geologic age, mineral resources, mass movements, geomorphology etc. in a single planar map/product. Nonetheless these graphic data-models do not allow retrieving individual thematic aspects since these were coded in a complex portrayal scheme. Automatic information retrieval is thus impossible; and domain knowledge is necessary to interpret these "encrypted datasets". With INSPIRE becoming effective and a variety of conceptual models (e.g. GeoSciML), built around a semantic framework (i.e. controlled vocabularies), being available it is necessary to develop a strategy and workflow for semantic harmonization of such datasets. In this contribution we demonstrate the development of a multistage workflow which will allow us to transform our printed maps to semantically enabled datasets and services and discuss some prerequisites, foundations and problems. In a first step in our workflow we analyzed our maps and developed controlled vocabularies that describe the thematic content of our data. We then developed a physical data-model which we use to attribute our spatial data with thematic information from our controlled vocabularies to form core thematic data sets. This physical data model is geared towards use on an organizational level but builds upon existing standards (INSPIRE, GeoSciML) to allow transformation to international standards. In a final step we will develop a standardized mapping scheme to publish INSPIRE conformant services from our core datasets. This two-step transformation is necessary since a direct mapping to international standards is not possible for traditional map-based data. Controlled vocabularies provide the foundation of a semantic harmonization. For the encoding of the vocabularies we build upon the W3C standard SKOS (=Simple Knowledge Organisation System), a thesaurus specification for the semantic web, which is itself based on the Resource Description Framework (RDF) and RDF Schema and added some DublinCore and VoID for the metadata of our vocabularies and resources. For the development of these thesauri we use the commercial software PoolParty, which is a tool specially build to develop, manage and publish multilingual thesauri. The corporate thesauri of the Austrian Geological Survey are exposed via a web-service that is conformant with the linked data principles. This web-service gives access to a (1) RDF/HTML representation of the resources via a simple, robust and thus persistent http URIs (2) a download of the complete vocabularies in RDF-format (3) a full-fledged SPARQL-Endpoint to query the thesaurus. With the development of physical data-models (based on preexisting conceptual models) one must dismiss the classical schemes of map-based portrayal of data. E.g. for individual Geological units on traditional geological maps usually a single age range is given (e.g. formation age). But one might want to attribute several geologic ages (formation age, metamorphic age, cooling ages etc.) to individual units. Such issues have to be taken into account when developing robust physical data-models. Based on our experience we are convinced that individual institutions need to develop their own controlled vocabularies and individual data-models that fit the specific needs on an organizational level. If externally developed vocabularies and data-models are introduced to established workflows newly generated and existing data may be diverging and it will be hard to achieve or maintain a common standard. We thus suggest that it is necessary for institutions to keep (or develop) to th

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
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.

Full Text Available The current study evaluated engineering college students’ self-regulated learning (SRL strategies while learning electric circuit concepts using enhanced guided notes (EGN. Our goal was to describe how students exercise SRL strategies and how their grade performance changes after using EGN. Two research questions guided the study: (1 To what degree students’ grade performance change after using the EGN?; and (2 To what degree students’ SRL profiles change after using the EGN? The subjects for this study were 97 engineering students enrolled in the Fundamental Electronics for Engineers course at a university in Utah. A survey instrument developed using Butler and Cartier’s SRL model was used to capture SRL strategies with a focus on the sixth feature which includes including planning, monitoring, and regulating. Regular examinations and the DC/AC conceptual inventory were used to assess grade performance. Descriptive statistics, independent and paired t-tests, and a cluster analysis technique were used to analyze survey data. A phenomenological data analysis was used to analyze interview transcripts to support findings from questionnaire data. The findings revealed an improvement on students’ grade performance. Data analysis of the SRL survey revealed that students’ had different SRL profiles. Students in the improved group reported a greater awareness of planning, monitoring, and regulating strategies. On the other hand, those in the declined group showed a lower awareness of the SRL strategies at the end of semester. In addition, emergent themes related to students’ SRL and learning experience while using the EGN were found. This article will also discuss the potential implications for electric circuit concepts instructions.

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

A growing number of papers have pointed out the relationship between aggressive resection of gliomas and survival prognosis. For maximum resection, the current concept of surgical decision-making is in "information-guided surgery" using multimodal intraoperative information. With this, anatomical information from intraoperative magnetic resonance imaging (MRI) and navigation, functional information from brain mapping and monitoring, and histopathological information must all be taken into account in the new perspective for innovative minimally invasive surgical treatment of glioma. Intraoperative neurofunctional information such as neurophysiological functional monitoring takes the most important part in the process to acquire objective visual data during tumor removal and to integrate these findings as digitized data for intraoperative surgical decision-making. Moreover, the analysis of qualitative data and threshold-setting for quantitative data raise difficult issues in the interpretation and processing of each data type, such as determination of motor evoked potential (MEP) decline, underestimation in tractography, and judgments of patient response for neurofunctional mapping and monitoring during awake craniotomy. Neurofunctional diagnosis of false-positives in these situations may affect the extent of resection, while false-negatives influence intra- and postoperative complication rates. Additionally, even though the various intraoperative visualized data from multiple sources contribute significantly to the reliability of surgical decisions when the information is integrated and provided, it is not uncommon for individual pieces of information to convey opposing suggestions. Such conflicting pieces of information facilitate higher-order decision-making that is dependent on the policies of the facility and the priorities of the patient, as well as the availability of the histopathological characteristics from resected tissue.

All methods presented to date to map both conductivity and permittivity rely on multiple acquisitions to compute quantitatively the magnitude of radiofrequency transmit fields, B1+. In this work, we propose a method to compute both conductivity and permittivity based solely on relative receive coil sensitivities ( B1-) that can be obtained in one single measurement without the need to neither explicitly perform transmit/receive phase separation nor make assumptions regarding those phases.

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 lmall-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.

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.
