Directory of Open Access Journals (Sweden)

Full Text Available This study investigated the relative effectiveness of three types of concept maps (hierarchy, flowchart and spider on the performance of students in Chemistry. This is with a view to find out which of the concept mapping types is more superior in enhancing students’ performance in the numerical aspect of Chemistry. The pre-test, post-test experimental design was used for the study. The population for the study comprised of all the Chemistry students in Senior Secondary School in Osun State of Nigeria. Students in Senior Secondary class two (SSII in their intact classes from three schools in Ife-Central local government area of the state formed the sample of the study. The three schools were randomly assigned to the hierarchical, flowchart and spider concept mapping strategies. The instrument used for data collection was the Problem Solving Achievement Test in Chemistry (PSATC. Students in the three groups were taught using the three kinds of concept maps separately. The experiment lasted for five weeks after which a post-test was administered. The result of the study indicated that there was no significant difference in the performances of the students in the three groups with respect to the kind of concept map used. (F = 1.088; p > 0.05. This implies that the concept mapping strategies were not all that different in their superiority. They all produced a similar effect on the students with respect to their performance in Chemistry. However, it was found out that they enhanced the performance of students in their problem solving skills in Chemistry as already reported by research studies.

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

Science.gov (United States)

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

Online Exhibits & Concept Maps  

Science.gov (United States)

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.

Mapping Knowledge: Concept Maps in Early Childhood Education  

Directory of Open Access Journals (Sweden)

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.

Concept Mapping for Higher Order Thinking  

Directory of Open Access Journals (Sweden)

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

Motivating Students' Learning Using Word Association Test and Concept Maps  

Directory of Open Access Journals (Sweden)

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.

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.

This qualitative study examined seven preservice teachers' perceptions of their science content knowledge, teaching practices, and reflective processes through the use of the metacognitive strategy of concept maps. Included in the paper is a review of literature in the areas of preservice teachers' perceptions of teaching, concept development, concept mapping, science content understanding, and reflective process as a part of metacognition. The key questions addressed include the use of concept maps to indicate organization and understanding of science content, mapping strategies to indicate perceptions of teaching practice, and the influence of concept maps on reflective process. There is also a comparison of preservice teachers' perceptions of concept map usage with the purposes and practices of maps as described by experienced teachers. Data were collected primarily through interviews, observations, a pre and post concept mapping activity, and an analysis of those concept maps using a rubric developed for this study. Findings showed that concept map usage clarified students' understanding of the organization and relationships within content area and that the process of creating the concept maps increased participants' understanding of the selected content. The participants felt that the visual element of concept mapping was an important factor in improving content understanding. These participants saw benefit in using concept maps as planning tools and as instructional tools. They did not recognize the use of concept maps as assessment tools. When the participants were able to find personal relevance in and through their concept maps they were better able to be reflective about the process. The experienced teachers discussed student understanding and skill development as the primary purpose of concept map usage, while they were able to use concept maps to accomplish multiple purposes in practice.

Using concept maps in cognitive treatment for children with developmental coordination disorder  

Directory of Open Access Journals (Sweden)

Full Text Available Children with Developmental Coordination Disorder (DCD often seem to possess a narrow repertoire of cognitive strategies. In particular, they have difficulties in learning and internalizing the rules and strategies that other people intuitively use to approach common everyday problems. As a result, they often appear to have organizational, planning, memory and learning difficulties. The article proposes using a Concept Map (CM as a visual strategy to facilitate interaction between a child with DCD, his/her family and therapist, as reflected in Client Centred and cognitive approaches. The CM is used as a method of assisting the child to identify, develop and utilize cognitive strategies in order to manage daily tasks effectively, as a tool in organizing his own therapy and in order to encourage participation. A demonstration of the concept mapping usefulness is brought by a case report. Further uses of concept mapping as a useful strategy within the framework of intervention remain to be studied.

Conceptology: Using Concept Map for Knowledge Representation and Ontology Construction  

Directory of Open Access Journals (Sweden)

Full Text Available Tools on using concept map for knowledge representation, ontology for domain rule generation and conversion from concept map to ontology are invented over recent years. Some focus on graphical representation, such as concept map, of domain knowledge for better user understanding, while others introduce rules that concept map fails to represent to extend the contents of generated ontology. To combine both advantages, a tool Conceptology is presented. In the context of MVB (Multifunction Vehicle Bus standard domain, a group of generation rules from enriched concept map to OWL (Web Ontology Language are presented, and Conceptology offers implementation of proposed rules to support graphical representation of MVB domain knowledge and conversion from concept map to OWL. Two Conceptology application cases from MVB standards are demonstrated.

Concept mapping and pupils’ learning in primary science in Singapore  

Directory of Open Access Journals (Sweden)

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

Heliophysics Concept Maps for Education and Public Outreach  

Science.gov (United States)

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

Concept maps about chemical equilibrium and students' achievement scores  

Science.gov (United States)

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.

Semantic mappings and locality of nursing diagnostic concepts in UMLS.  

Science.gov (United States)

One solution for enhancing the interoperability between nursing information systems, given the availability of multiple nursing terminologies, is to cross-map existing nursing concepts. The Unified Medical Language System (UMLS) developed and distributed by the National Library of Medicine (NLM) is a knowledge resource containing cross-mappings of various terminologies in a unified framework. While the knowledge resource has been available for the last two decades, little research on the representation of nursing terminologies in UMLS has been conducted. As a first step, UMLS semantic mappings and concept locality were examined for nursing diagnostic concepts or problems selected from three terminologies (i.e., CCC, ICNP, and NANDA-I) along with corresponding SNOMED CT concepts. The evaluation of UMLS semantic mappings was conducted by measuring the proportion of concordance between UMLS and human expert mappings. The semantic locality of nursing diagnostic concepts was assessed by examining the associations of select concepts and the placement of the nursing concepts on the Semantic Network and Group. The study found that the UMLS mappings of CCC and NANDA-I concepts to SNOMED CT were highly concordant to expert mappings. The level of concordance in mappings of ICNP to SNOMED CT, CCC and NANDA-I within UMLS was relatively low, indicating the need for further research and development. Likewise, the semantic locality of ICNP concepts could be further improved. Various stakeholders need to collaborate to enhance the NLM knowledge resource and the interoperability of nursing data within the discipline as well as across health-related disciplines.

ENGLISH LANGUAGE TEACHING WITH AN ELECTRONIC CONCEPT MAPPING  

Directory of Open Access Journals (Sweden)

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

Concept Mapping: Linking Spheres in Earth System Science  

Science.gov (United States)

The Earth System Science Education Alliance (ESSEA) distance learning courses focus teachers on linking spheres of the earth: atmosphere, hydrosphere, lithosphere and biosphere. The University of Toledo has offered the ESSEA middle school grade course using jigsaw pedagogy nine times since 2002. Traditionally, the ESSEA course has teachers link spheres in linear causal chains. This past year we used concept mapping as a way for the teachers and pre-service students in the class to organize their study of the events: melting of ice sheets, Mt. Pinatubo eruption, Hurricane Katrina and draining of the Great Black Swamp. Concept mapping is a good way to visualize linkages between events and spheres. The outcome was that teachers and pre-service students enjoyed concept mapping, it fostered teamwork and helped with grading the material.

Concept mapping a baccalaureate nursing program: a method for success.  

Science.gov (United States)

The understanding of curricular design and development is paramount for faculty. For novice faculty, learning teaching methods commonly takes precedence over understanding curriculum development. Professional accrediting bodies of nursing programs require curriculum course content to be pertinent and flow logically. Baccalaureate nursing programs can choose to be accredited by the Commission on Collegiate Nursing Education. The purpose of this article is to describe an educational innovation that one College of Nursing implemented to orient new faculty to the curriculum and prepare for an accreditation renewal. Assigned faculty developed and implemented a concept mapping process aimed to evaluate and revise course content based on national standards and guidelines. Undergraduate faculty understanding and ownership of the curriculum was evident throughout the process. The concept mapping process proved to be an innovative approach to enhance the curriculum and equip faculty with an understanding of the relationship between concepts and course content.

Urban Noise and Strategies of Sound Mapping  

DEFF Research Database (Denmark)

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 â?? a method that may supplement the engineerâ??s quantitative sound measurements and the landscape architectâ??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.

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

Directory of Open Access Journals (Sweden)

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.

Advances in BAC-Based Physical Mapping and Map Integration Strategies in Plants  

Digital Repository Infrastructure Vision for European Research (DRIVER)

In the advent of next-generation sequencing (NGS) platforms, map-based sequencing strategy has been recently suppressed being too expensive and laborious. The detailed studies on NGS drafts alone indicated these assemblies remain far from gold standard reference quality, especially when applied on complex genomes. In this context the conventional BAC-based physical mapping has been identified as an important intermediate layer in current hybrid sequencing strategy. BAC-based physical map cons...

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

Science.gov (United States)

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.

Investigating the nature of third grade students' experiences with concept maps to support learning of science concepts  

Science.gov (United States)

To support and improve effective science teaching, educators need methods to reveal student understandings and misconceptions of science concepts and to offer all students an opportunity to reflect on their own knowledge construction and organization. Students can benefit by engaging in scientific activities in which they build personal connections between what they learn and their own experiences. Integrating student-constructed digital concept mapping into the science curriculum can reveal to both students and teachers the conceptual organization and understanding of science content, which can assist in building connections between concepts and personal experiences. I used a qualitative case study research design in which my setting was one third-grade classroom. Participants were the teacher and student in this classroom. This paper describes how a class of third grade students used concept maps to understand science concepts (specifically, "watershed systems"). During class discussions and interviews students revised concept map content and structure as their ideas developed. The results of this study demonstrated how students' understandings and misconceptions were revealed through their construction of digital concept maps over time. Each new concept map built upon the previous one for a total of seven maps per student. Analyses of the concept maps using an evaluative rubric revealed changes over time in concept map structure and content. A formal assessment of watershed concepts was administered four times during the course of the science unit. I conclude that my research model used for integrating concept maps in this science class enabled students to reflect deeply on their work and to accurately revise their knowledge construction and content. Using concept maps to inform her teaching, the teacher also made robust use of the research model.

The Effectiveness of Concept Maps in Teaching Physics Concepts Applied to Engineering Education: Experimental Comparison of the Amount of Learning Achieved With and Without Concept Maps  

Science.gov (United States)

A study was conducted to quantify the effectiveness of concept maps in learning physics in engineering degrees. The following research question was posed: What was the difference in learning results from the use of concept maps to study a particular topic in an engineering course? The study design was quasi-experimental and used a post-test as a measuring instrument. The sample included 114 university students from the School of Industrial Engineering who were divided into two equivalent homogeneous groups of 57 students each. The amount of learning attained by the students in each group was compared, with the independent variable being the teaching method; the experimental group (E.G.) used concept maps, while the control group (C.G.) did not. We performed a crossover study with the two groups of students, with one group acting as the E.G. for the topic of optical fibers and as the C.G. for the topic of the fundamental particles of matter and vice versa for the other group. For each of the two topics studied, the evaluation instrument was a test of 100 dichotomous items. The resulting data were subjected to a comparative statistical analysis, which revealed a significant difference in the amount of learning attained by the E.G. students as compared with the C.G. students. The results allow us to state that for the use of concept maps, the average increment in the E.G. students' learning was greater than 19 percentage points.

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

Science.gov (United States)

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

Concept maps and the meaningful learning of science  

Directory of Open Access Journals (Sweden)

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

Requirements and design concept for a facility mapping system  

International Nuclear Information System (INIS)

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

Research on the Approach of Automatic Construct Concept Maps from Online Course  

Directory of Open Access Journals (Sweden)

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

As educators begin to implement the use of concept mapping in their classrooms, it will be important to better understand how it can best support student learning. I am presently looking at how concept mapping software can enhance the learner’s experience as they seek deeper meaning of core concepts. While the use of a dual coding process with concept mapping has been popular for decades, the opportunity to enhance student learning with a more sophisticated three dimensional software mapping product is relatively new. Through my studies and my practices of implementing multi-dimensional concept mapping pedagogy, I am discovering new insights into how this approach can support student learning.

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.

Discrimination of mixed quantum states. Reversible maps and unambiguous strategies  

International Nuclear Information System (INIS)

The discrimination of two mixed quantum states is a fundamental task in quantum state estimation and quantum information theory. In quantum state discrimination a quantum system is assumed to be in one of two possible - in general mixed - non-orthogonal quantum states. The discrimination then consists of a measurement strategy that allows to decide in which state the system was before the measurement. In unambiguous state discrimination the aim is to make this decision without errors, but it is allowed to give an inconclusive answer. Especially interesting are measurement strategies that minimize the probability of an inconclusive answer. A starting point for the analysis of this optimization problem was a result by Eldar et al. [Phys. Rev. A 69, 062318 (2004)], which provides non-operational necessary and sufficient conditions for a given measurement strategy to be optimal. These conditions are reconsidered and simplified in such a way that they become operational. The simplified conditions are the basis for further central results: It is shown that the optimal measurement strategy is unique, a statement that is e.g. of importance for the complexity analysis of optimal measurement devices. The optimal measurement strategy is derived for the case, where one of the possible input states has at most rank two, which was an open problem for many years. Furthermore, using the optimality criterion it is shown that there always exists a threshold probability for each state, such that below this probability it is optimal to exclude this state from the discrimination strategy. If the two states subject to discrimination can be brought to a diagonal structure with (2 x 2)-dimensional blocks, then the unambiguous discrimination of these states can be reduced to the unambiguous discrimination of pure states. A criterion is presented that allows to identify the presence of such a structure for two self-adjoint operators. This criterion consists of the evaluation of three commutators and allows an explicit construction of the (2 x 2)-dimensional blocks. As an important application of unambiguous state discrimination, unambiguous state comparison, i.e., the question whether two states are identical or not, is generalized and optimal measurements for this problem are constructed. If for a certain family of states, a physical device maps the input state to an output state, such that a second device can be built that yields back the original input state, such a map is called reversible on this family. With respect to state discrimination, such reversible maps are particularly interesting, if the output states are pure. A complete characterization of all families that allow such a reversible and purifying map is provided. If the states are mapped to pure states, but the map itself is not reversible, upper and lower bounds are analyzed for the ''deviation from perfect faithfulness'', a quantity which measures the deviation from a reversible mapping.

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.

A Study of the Relationship between English Self-concept and Language Learning Strategies  

Directory of Open Access Journals (Sweden)

Full Text Available The present study concentrated on the relationship between self-concept and language learning strategies. Participants of the study were 157 students from one University in Shandong, China. Quantitative data was collected through two questionnaires. The first one was the revised Chinese version of self-concept scale modified by Pan (2003 from Marsh’s (1992 SQDII. Another inventory based on Oxford’ classification system of learning strategies (SILL was used to assess learner’s strategy use. By the reliability analysis, it was found that all these coefficients were significantly high, and the two questionnaires were reliable respectively. Based on the detailed analysis of data, some major findings through statistical analysis of SPSS 13.0 were summarized as follows. First of all, the subjects’ English self-concept was medium, and the subjects’ English pronunciation self-concept was better than their general English self-concept and English speaking self-concept. Second, gender had no significant effects on the general English self-concept and English speaking self-concept. Finally, in terms of the relationship between English self-concept and language learning strategies, by Pearson correlation coefficients and multiple regressions, it was concluded that general English self-concept, English speaking self-concept and English pronunciation self-concept had the highest correlation level with the cognitive strategy, and English pronunciation self-concept had the weakest correlation level with the memory strategy and compensatory strategy. The findings of the study imply that there are some pedagogical implications for English learning and teaching. At the same time, teachers should attach importance to enhancing students’ English self-concept level in training their language learning strategies.

Building reliable genetic maps: different mapping strategies may result in different maps  

Directory of Open Access Journals (Sweden)

Full Text Available New high throughput DNA technologies resulted in a disproportion between the high number of scored markers for the mapping populations and relatively small sizes of the genotyped populations. Correspondingly, the number of markers may, by orders of magnitude, exceed the threshold of recombination resolution achievable for a given population size. Hence, only a small part of markers can be genuinely ordered in the map. The question is how to choose the most informative markers for building such a reliable “skeleton” map. We believe that our approach provides a solution to this difficult problem due to: a powerful tools of discrete optimization for multilocus ordering; b a verification procedure, which is impossible without fast and high-quality optimization, to control the map quality based on re-sampling techniques; c an interactive algorithm of marker clustering in complicated situations caused by significant deviation of recombination rates between markers of non-homologous chromosomes from the expected 50% (referred to as quasi-linkage or pseudo-linkage; and d an algorithm for detection and removing excessive markers to increase the stability of multilocus ordering.

Utilization Practice of the Concept Mapping Program for Nuclear Engineer Training  

International Nuclear Information System (INIS)

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

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 knowledg...

An Accelerated ISAF Algorithm with the Fast Mapping Strategy  

Directory of Open Access Journals (Sweden)

Full Text Available ISAF (icosahedral symmetry-adapted functions is a new approach used for 3D reconstruction of icosahedral macromolecules, which can achieve better resolutions compared with the commonly used Fourier-Bessel algorithm. However, ISAF is significantly slow. Among all reasons, the operation that rotating each image sixty times costs lots of running time. By analyzing the sixty symmetrical characteristics of icosahedrons in Fourier space, we proved that the positions of sixty mapped points derived from one sampling point are all the same in asymmetric unit. Thus, the sixty symmetrical rotating of each image can be removed and the reconstruction speed is increased. This accelerating strategy was validated by means of experiments with simulated data and experimental Cryo-EM data. The results showed that the speedup of this strategy was up to 41 times and it could grow up with the increase of the maximum Fourier radius and the number of images at the premise of maintenance of accuracy. Its running speed is about 9 times as great as that of Fourier-Bessel algorithm and is about 3 times than that of recISAFs algorithm.

Functional Ontology and Concept Maps for Knowledge Navigation: An Application Example for Contest Robot  

Directory of Open Access Journals (Sweden)

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.

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

International Nuclear Information System (INIS)

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

Generating Intelligent Teaching-Learning Systems using Concept Maps and Case-Based Reasoning.  

Directory of Open Access Journals (Sweden)

Full Text Available The use of pedagogical methods with the technologies of the information and communications produce a new quality that favors the task of generating, transmitting and sharing knowledge. Such is the case of the pedagogical effect that produces the use of the Concept Maps, which constitute a tool for the management of knowledge, an aid to personalize the learning process, to exchange knowledge, and to learn how to learn. Concept Mapping provides a framework for making this internal knowledge explicit in a visual form that can easily beexamined and shared. However, it does not address how relevant Concept Maps can be retr ieved or adapted to new problems. Case-Based Reasoning is playing an increasing role in knowledge retrieval and reuse for corporate memories, and its capabilities are appealing to augment the concept mapping process. In this paper the authors present a new approach to elaborate Intelligent Teaching-Learning Systems, where the techniques of Concept Maps and Artificial Intelligence are combined, using the Case-Based Reasoning as theoretical framework for the Student Model. The proposed model has been implemented in the computational system HESEI, which has been successfully applied in the teaching-learning process by laymen in the Computer Science field.

ADDRESSING WATER FOOTPRINT CONCEPT: A DEMONSTRABLE STRATEGY FOR PAPERMAKING INDUSTRY  

Directory of Open Access Journals (Sweden)

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.

Concept Maps as Expressions of Teachers' Meaning-Making while Beginning to Teach Semiconductors  

Science.gov (United States)

The challenge of teaching new subject matter is a familiar one for most teachers. This paper investigates the content knowledge gains made by seven teachers as they learn to teach the topic of semiconductors through a process of self-study. `Semiconductors' is a new topic in the curriculum which looks at the sub-microscopic properties of materials used in electronics and is important because of its applications in modern technology. We present a phenomenographic analysis of 21 concept maps produced by seven teachers at various stages of their self-study project. Four categories of description emerged in the analysis, viz. no meaning, orientation to understanding of subject matter (SMK), a pedagogical content knowledge (PCK) context focus, and a PCK strategy focus. The last category proved to be the most interesting as it suggested that the teacher saw the learning of SMK and learning to teach the SMK as a single process. This finding was considered as important in understanding how teachers learn new SMK for teaching. We found that experienced teachers make sense of their new SMK in different ways. There is a variation of orientation in their learning and sense-making. The data also showed progression of teachers' understanding of the topic through the self-study process. The findings suggest that learning SMK for the purposes of teaching is different to learning for fulfilling the requirements of a study programme.

Evaluating a Concept Mapping Training Programme by 10 and 13 year-old students  

Directory of Open Access Journals (Sweden)

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 use of concept maps to detect and correct concept errors (mistakes  

Directory of Open Access Journals (Sweden)

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.

Concept, components, and strategies of soil health in agroecosystems.  

Science.gov (United States)

The terms ''soil health'' or ''soil quality'' as applied to agroecosystems refer to the ability of soil to support and sustain crop growth while maintaining environmental quality. High-quality soils have the following characteristics: (i) a sufficient, but not excess, supply of nutrients; (ii) good structure (tilth); (iii) sufficient depth for rooting and drainage; (iv) good internal drainage; (v) low populations of plant disease and parasitic organisms; (vi) high populations of organisms that promote plant growth; (vii) low weed pressure; (viii) no chemicals that might harm the plant; (ix) resistance to being degraded; and (x) resilience following an episode of degradation. Management intended to improve soil health involves creatively combining a number of practices that enhance the soil's biological, chemical, and physical suitability for crop production. The most important general strategy is to add plentiful quantities of organic matter-including crop and cover crop residues, manures, and composts. Other important strategies include better crop rotations, reducing tillage and keeping the soil surface covered with living and dead residue, reducing compaction by decreasing heavy equipment traffic, and using best nutrient management practices. Practices that enhance soil quality frequently reduce plant pest pressures. PMID:19265876

Resizing Auditory Communities : Urban noise and strategies of sound mapping  

DEFF Research Database (Denmark)

Heard through the ears of the Canadian composer and music teacher R. Murray Schafer the ideal auditory community had the shape of a village. Schaferâ??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 Schaferâ??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.

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

Science.gov (United States)

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

Concept Mapping to Assess Learning and Understanding of Complexity in Courses on Global Climate Change  

Science.gov (United States)

The complex nature of climate change science poses special challenges for educators wishing to broaden and deepen student understanding of the climate system and its sensitivity to and impacts upon human activity. Learners have prior knowledge that may limit their perception and processing of the multiple relationships between processes (e.g., feedbacks) that arise in global change science, and these existing mental models serve as the scaffold for all future learning. Because adoption of complex scientific concepts is not likely if instruction includes presentation of information or concepts that are not compatible with the learners’ prior knowledge, providing effective instruction on this complex topic requires learning opportunities that are anchored upon an evaluation of the limitations and inaccuracies of the learners’ existing understandings of the climate system. The formative evaluation that serves as the basis for planning such instruction can also be useful as a baseline against which to evaluate subsequent learning. We will present concept-mapping activities that we have used to assess students’ knowledge and understanding about global climate change in courses that utilized multiple assessment methods including presentations, writings, discussions, and concept maps. The courses in which these activities were completed use a variety of instructional approaches (including standard lectures and lab assignments and a mock summit) to help students understand the inherently interdisciplinary topic of global climate change, its interwoven human and natural causes, and the connections it has with society through a complex range of political, social, technological and economic factors. Two instances of concept map assessment will be presented: one focused on evaluating student understanding of the major components of the climate system and their interconnections, and the other focused on student understanding of the connections between climate change and the global food system. We will discuss how concept mapping can be used to demonstrate evidence of learning and conceptual change, and also how it can be used to provide information about gaps in knowledge and misconceptions students have about the topic.

Novel Translational Research Concepts and Strategies in Radiation Oncology  

Directory of Open Access Journals (Sweden)

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.

Critical analysis of the excitation map concept for studying threshold effects in VLEED  

Energy Technology Data Exchange (ETDEWEB)

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 (Vertical Bardet (1 - M/sup - +/R/sup + -/)Vertical Bar where M/sup - +/ is the reflection matrix of the atomic planes and R/sup + -/ 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.

Using Concept Mapping for Needs Analysis for a Social Support System in Learning Network  

Directory of Open Access Journals (Sweden)

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 theory underlying concept maps and how to construct and use them  

Directory of Open Access Journals (Sweden)

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.

Both in academic literature and political practice, resilience is becoming a central evaluative concept for assessing climate adaptation policies. This makes sense because society's main challenge in an altering the environment is to adapt to the inevitable changes. However, applying the concept of resilience to devise adaptation strategies reveals that social-ecological resilience acquires different meanings depending on the social context. There is no straightforward application of res...

Semantic concept detection is a very useful technique for developing powerful retrieval or filtering systems for multimedia data. To date, the methods for concept detection have been converging on generic classification schemes. However, there is often imbalanced dataset or rare class problems in classification algorithms, which deteriorate the performance of many classifiers. In this paper, we adopt three “under-sampling” strategies to handle this imbalanced dataset issue in a SVM classi...

Furthermore, the article employs Arthur Lykke’s definition of strategy to demonstrate various conceptual requirements. Strategy is thus perceived as the relationship among means, ends, and ways. Crucial implications for a development of the Czech strategic documents are further examined. The article argues that, the vital importance of coherent interconnection of all the afore-mentioned parts of the strategy has been so far neglected in this process. It is suggested that particular attention should be paid to the clear formulation of a goal, which is the prerequisite for any meaningful strategy. However, any goals must be developed with the close relation to the available or potentially attainable resources, and purposeful ways how to employ them. The whole process is best described as the hermeneutic circle.

The influence of concept mapping on critical thinking in baccalaureate nursing students.  

Science.gov (United States)

This article describes a quasi-experimental study that used a pretest-posttest design with a control group to evaluate the effectiveness of concept mapping in developing critical thinking skills in baccalaureate nursing students. A convenience sample (n = 76) was randomly assigned to experimental (n = 44) and control (n = 32) groups. The experimental group was taught to use concept mapping of patient information to prepare for clinical experiences. The control group was taught to use traditional nursing care plans. Critical thinking skills were measured with the California Critical Thinking Skills Test, which yielded six scores: an overall score and five subscales (analysis, evaluation, inference, deductive reasoning, and inductive reasoning). A significant difference (p <.05) was found between the mean pretest and posttest scores and each subscale. Post hoc tests found differences between groups to be insignificant, while various differences within a group were significant. Experimental-group scores improved significantly (p <.05) on the overall score and the analysis and evaluation subscales, while control-group scores improved significantly only on the evaluation subscale and declined significantly on the inference subscale. The findings suggest that concept mapping is effective in helping students develop critical thinking skills. PMID:14689390

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

DEFF Research Database (Denmark)

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.

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

Directory of Open Access Journals (Sweden)

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

Application of Modular Integrated Utility Systems (MIUS) concept as a strategy for urban rehabilitation and redevelopment  

Energy Technology Data Exchange (ETDEWEB)

The potential role of the Modular Integrated Utility System (MIUS) as a strategy for implementing urban redevelopment and rehabilitation objectives is assessed. Major environmental, utility infrastructure, and national policy constraints to urban redevelopment efforts are examined. The emphasis is on high-density urban areas of major cities where planned redevelopment and rehabilitation efforts could be seriously impeded by lack of existing utility infrastructures, inadequate service, and restrictive environmental legislation. The current status of air quality, potable water quality, regional solid waste disposal capacity, and capabilities of liquid waste treatment systems is described for the nation's 100 largest metropolitan areas. The MIUS concept is evaluated as a community development strategy capable of complying with environmental regulations, upgrading utility services, and supporting high-density urban development. Examples are developed which indicate that the MIUS concept could be used in high-density residential and commercial areas to permit development without major disruptions to surrounding areas. A case study of Philadelphia, Pennsylvania was undertaken to characterize the role of MIUS in an existing urban environment. Housing patterns, planned redevelopment efforts, concerns for community ethnic integrity, high utility costs, and a proposed metropolitan district heating system make the MIUS concept attractive for Philadelphia's urban strategy.

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

Directory of Open Access Journals (Sweden)

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.

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

Scientific Electronic Library Online (English)

Full Text Available SciELO South Africa | Language: English Abstract in english 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.

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

International Nuclear Information System (INIS)

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

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

Directory of Open Access Journals (Sweden)

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.

Concepts for landscape scale digital soil mapping using field scale geophysical sensor data  

Science.gov (United States)

An essential prerequisite for site-specific soil protection and restoration, alongside sustainable land use, water management, and environmental management, is the availability of high-resolution soil property maps. One aim of the iSOIL project (EU FP7) was the validation of the potential of field-scale proximal soil sensing for landscape-scale Digital Soil Mapping (DSM). Within the iSOIL project we applied a combination of several preprocessing approaches to determine where the sensors should be applied. In a first step the landscape was segmented into homogeneous landscape units and in a second step representative patches or spatial subsets were derived as core areas for soil sensing. This talk presents and compares multiple approaches to integrate these patch-scale geophysical sensing data (EM and Gamma) into landscape scale DSM. Hyper-scale digital terrain features (ConMap) were used as the only predictors for building the regression models. Eighty calibration samples covering the feature space of the interpolated geophysical sensor data were used for building the soil property models. Validation was based on 20 fully independent samples outside the sampling areas covering the geographical space. Validation shows that some approaches do not show any benefit compared to our benchmark model, where no geophysical data was included. However, one concept returns a boost in R2 validation accuracy of up to 11 %. This demonstrates that it is crucial how the field scale geophysical data is included in landscape scale DSM frameworks and that field scale geophysical data can successfully be used for landscape scale DSM.

Development and evaluation of RapTAT: A machine learning system for concept mapping of phrases from medical narratives.  

Science.gov (United States)

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.

Health risk in the context of climate change and adaptation - Concept and mapping as an integrated approach  

Science.gov (United States)

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.

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

Science.gov (United States)

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.

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

Directory of Open Access Journals (Sweden)

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.

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

Science.gov (United States)

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

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

Science.gov (United States)

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.

Mapping the future of environmental health and nursing: strategies for integrating national competencies into nursing practice.  

Science.gov (United States)

:Nurses are increasingly the primary contact for clients concerned about health problems related to their environment. In response to the need for nursing expertise in the field of environmental health, the Institute of Medicine (IOM), Agency for Toxic Substances and Disease Registry (ATSDR), and National Institute of Nursing Research (NINR) have designed core competencies for the nursing profession. The IOM competencies focus on four areas: (1) knowledge and concepts; (2) assessment and referral; advocacy, ethics, and risk communication; and (4) legislation and regulation. The competencies establish a baseline of knowledge and awareness in order for nurses to prevent and minimize health problems associated with exposure to environmental agents. To address the known difficulties of incorporating new priorities into established practice, nurses attending an environmental health short course participated in a nominal group process focusing on the question, "What specific actions can we take to bring environmental health into the mainstream of nursing practice?" This exercise was designed to bring the concepts of the national initiatives (IOM, NINR, ATSDR) to the awareness of individual nurses involved in the direct delivery of care. Results include 38 action items nurses identified as improving awareness and utilization of environmental health principles. The top five ideas were: (1) get environmental health listed as a requirement or competency in undergraduate nursing education; (2) improve working relationships with interdepartmental persons-a team approach; (3) strategically place students in essential organizations such as NIOSH, ATSDR, or CDC; (4) educate nurse educators; and (5) create environmental health awards in nursing. The 38 original ideas were also reorganized into a five-tiered conceptual model. The concepts of this model include: (1) developing partnerships; (2) strengthening publications; (3) enhancing continuing education; (4) updating nursing practice; and (5) strengthening schools of nursing. The model serves as a road map for action in building environmental health capacity within mainstream nursing. PMID:12071904

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

DEFF Research Database (Denmark)

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

A hierarchy of associations in hippocampo-cortical systems: cognitive maps and navigation strategies.  

Science.gov (United States)

In this letter we describe a hippocampo-cortical model of spatial processing and navigation based on a cascade of increasingly complex associative processes that are also relevant for other hippocampal functions such as episodic memory. Associative learning of different types and the related pattern encoding-recognition take place at three successive levels: (1) an object location level, which computes the landmarks from merged multimodal sensory inputs in the parahippocampal cortices; (2) a subject location level, which computes place fields by combination of local views and movement-related information in the entorhinal cortex; and (3) a spatiotemporal level, which computes place transitions from contiguous place fields in the CA3-CA1 region, which form building blocks for learning temporospatial sequences. At the cell population level, superficial entorhinal place cells encode spatial, context-independent maps as landscapes of activity; populations of transition cells in the CA3-CA1 region encode context-dependent maps as sequences of transitions, which form graphs in prefrontal-parietal cortices. The model was tested on a robot moving in a real environment; these tests produced results that could help to interpret biological data. Two different goal-oriented navigation strategies were displayed depending on the type of map used by the system. Thanks to its multilevel, multimodal integration and behavioral implementation, the model suggests functional interpretations for largely unaccounted structural differences between hippocampo-cortical systems. Further, spatiotemporal information, a common denominator shared by several brain structures, could serve as a cognitive processing frame and a functional link, for example, during spatial navigation and episodic memory, as suggested by the applications of the model to other domains, temporal sequence learning and imitation in particular.

A Study on Language Learning Strategy Use and Its Relation to Academic Self-concept: The Case of EFL Students in Taiwan  

Directory of Open Access Journals (Sweden)

Full Text Available The current study investigates the language learning strategy use (LLSU among EFL university freshmen and its relation to academic self-concept (ASC. Of six strategy categories, compensation strategies were reported as the most frequently used and social strategies were the least used. Participants with low and medium ASC used compensation strategies the most, while the participants of high ASC used metacognitive strategies the most. A significant positive relationship between strategy use and ASC was identified. All six strategy categories were found to be significant regarding different ASC of the research participants while only three particular strategy items were not. Among the strategy categories, metacognitive and cognitive strategies were found to have the highest correlations with ASC. Among the two components of ASC, academic effort was more highly related to overall strategy use than academic confidence. Educational implications and suggestions from the current study are presented to benefit the promotion of ASC and LLSU.

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

Directory of Open Access Journals (Sweden)

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

Narcotic analgesic utilization amongst injured workers: using concept mapping to understand current issues from the perspectives of physicians and pharmacists  

Directory of Open Access Journals (Sweden)

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.

Concept map analysis in the assessment of speech-language pathology students' learning in a problem-based learning curriculum: a longitudinal study.  

Science.gov (United States)

The aim of this study was to track students' critical thinking performance longitudinally through concept map analysis in a problem-based learning (PBL) curriculum. Concept map analysis has been employed in the assessment of students' critical thinking in medical education. Little is known concerning concept mapping (CM) in speech-language pathology (SLP) education. In this quantitative study, students in a 4-year SLP education program (N = 38) were followed until the completion of a fully-integrated PBL curriculum from Years 1 to 3. Students' concept maps were analyzed using a tool developed for this study, the Concept Map Assessment Profile (CMAP). There was an increase in concept map scores across the 3 years at the beginning of the academic year. The CM performance over the 3 years predicted 21.0% to 33.6% of variance in three measures of learning outcomes. The CMAP is a reliable measure, with strong inter-rater and intra-rater reliability (r = 0.85 and r = 0.96, respectively). In addition to its use as an assessment tool, the CMAP might be used to facilitate students' learning as feedback concerning strengths and weaknesses in the development of critical thinking can be provided.

Application of genetic algorithm with genetic modification and quality map in production strategy optimization; Aplicacao de algoritmo genetico com modificacao genetica e mapa de qualidade na otimizacao de estrategia de producao  

Energy Technology Data Exchange (ETDEWEB)

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.

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

International Nuclear Information System (INIS)

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

An integrated approach to analyze strategy map using BSC – FUZZY AHP: A case study of auto industry  

Directory of Open Access Journals (Sweden)

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.

An Integrative Hierarchical Stepwise Sampling Strategy For Spatial Sampling And Its Application In Digital Soil Mapping  

Science.gov (United States)

Sampling design plays an important role in spatial modeling. Existing methods often require large amount of samples to achieve desired mapping accuracy but imply considerable cost. When there are not enough resources for collecting a large set of samples at once, stepwise sampling approach is often the only option for collecting the needed large sample set, especially in the case of field surveying over large areas. This paper proposes an integrative hierarchical stepwise sampling strategy which makes the samples collected at different stages an integrative one. The strategy is based on samples' representativeness of the geographic feature at different scales. The basic idea is to sample at locations that are representative of large-scale spatial patterns first and then add samples that represent more local patterns in a stepwise fashion. Based on the relationships between geographic feature and its environmental covariates, the proposed sampling method approximates a hierarchy of spatial variations of the geographic feature under concern by delineating natural aggregates (clusters) of its relevant environmental covariates at different scales. The natural occurrence of such aggregates is modeled using a fuzzy c-means clustering method. We iterate through different numbers of clusters from only a few to many more to be able to reveal clusters at different spatial scales. At a particular iteration, locations that bear high similarity to the cluster prototypes are identified. If a location is consistently identified at multiple iterations it is then considered to be more representative of the general or large-scale spatial patterns. Locations that are identified less during the iterations are representative of local patterns. The integrative stepwise sampling design then gives higher sampling priority to the locations that are more representative of the large scale patterns than local ones. We applied this sampling design in a digital soil mapping case study. Different representative samples were obtained and used for soil inference. We started with samples that are the most representative of the large scale patterns and then gradually include the samples representative of local patterns. Field evaluation indicated that the additions of more samples with lower representativeness lead to improvements of accuracy with a decreasing marginal gain. When cost-effectiveness is considered, the representative grade could provide essential information on the number and order of samples to be sampled for an effective sampling design.

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

Science.gov (United States)

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.

Self-Regulated Learning Strategies of Engineering College Students While Learning Electric Circuit Concepts with Enhanced Guided Notes  

Directory of Open Access Journals (Sweden)

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.

Contingency maneuver strategies for the Total Ozone Mapping Spectrometer-Earth Probe (TOMS-EP)  

Science.gov (United States)

The Total Ozone Mapping Spectrometer-Earth Probe (TOMS-EP) is a polar-orbiting spacecraft designed to measure total ozone levels in the Earth's atmosphere. The nominal mission orbit is a 955-kilometer circular Sun-synchronous orbit with an ascending node mean local crossing time (MLT) between 11:02 a.m. and 11:25 a.m. These two mean local ascending node times constitute the boundaries of the MLT box for this mission. The MLT boundaries were chosen to maintain the Sun-to-Earth-to-vehicle orbit-normal (SVN) angle within a preselected set of seasonally independent boundaries. Because the SVN angle is seasonally dependent, but the MLT is not, contingency options for correcting the MLT of orbital states that fall outside of the required MLT range become time dependent. This paper focuses on contingency orbit adjustment strategies developed at the Goddard Space Flight Center (GSFC) Flight Dynamics Division (FDD) during the mission planning phase of TOMS-EP. Time-dependent delta-V strategies are presented for correcting mission orbit states lying outside of the MLT range. Typically, passive control of the MLT drift rate can be used to restore the orbit state to the required MLT before a seasonal violation of SVN angle constraints can occur. Passive control of the MLT drift rate is obtained through adjustment of the semimajor axis and/or the inclination. The time between initial arrival on orbit at an 'out-of-the box' MLT state and violation of the SVN angle constraints is always less than or equal to 1 year. The choice of which parameter(s) to adjust is dictated by the duration of this time period, the desired mission lifetime, the delta-V cost, and operational constraints.

Towards a Sustainability Education Framework: Challenges, Concepts and Strategies—The Contribution from Urban Planning Perspectives  

Directory of Open Access Journals (Sweden)

Full Text Available Education for sustainability is becoming a critical component in achieving a sustainable life and protecting our planet and human habitats. However, a review of the sustainability literature reveals a great deal of confusion and misinterpretation regarding the concepts, themes, and goals of education for sustainability. Education for sustainability, including the themes that should be derived and taught, lacks an interdisciplinary conceptual framework. In addition, the literature of education for sustainability mostly lacks the aspects of urban and community planning and the significant contribution of the planning profession. This paper proposes a new conceptual framework, Sustainability Education Framework, which is composed of concepts that derived from different disciplines. At the heart of the conceptual framework rests the normative category and its concepts. The epistemological foundation of the conceptual framework of education for sustainability is based on the unresolved paradox between ‘sustainability’ and ‘development’.

A mutate-and-map strategy accurately infers the base pairs of a 35-nucleotide model RNA.  

Science.gov (United States)

We present a rapid experimental strategy for inferring base pairs in structured RNAs via an information-rich extension of classic chemical mapping approaches. The mutate-and-map method, previously applied to a DNA/RNA helix, systematically searches for single mutations that enhance the chemical accessibility of base-pairing partners distant in sequence. To test this strategy for structured RNAs, we have carried out mutate-and-map measurements for a 35-nt hairpin, called the MedLoop RNA, embedded within an 80-nt sequence. We demonstrate the synthesis of all 105 single mutants of the MedLoop RNA sequence and present high-throughput DMS, CMCT, and SHAPE modification measurements for this library at single-nucleotide resolution. The resulting two-dimensional data reveal visually clear, punctate features corresponding to RNA base pair interactions as well as more complex features; these signals can be qualitatively rationalized by comparison to secondary structure predictions. Finally, we present an automated, sequence-blind analysis that permits the confident identification of nine of the 10 MedLoop RNA base pairs at single-nucleotide resolution, while discriminating against all 1460 false-positive base pairs. These results establish the accuracy and information content of the mutate-and-map strategy and support its feasibility for rapidly characterizing the base-pairing patterns of larger and more complex RNA systems.

Water resource management under deep uncertainty: The concept and application of vulnerability maps  

Science.gov (United States)

Assessments of potential impacts of climate change on water resources are generally based on the use of downscaled climate scenarios to force hydrological models and hence estimate the changes in natural water availability in comparison to baseline conditions. This framework, however, suffers from various sources of uncertainty. First, climate models have large uncertainty associated with key climate variables such as precipitation. Second, downscaling approaches are based on several assumptions, which degrade their prediction capability for future conditions. Third, hydrological models are associated with a set of limitations due to lack of process understanding and data support as well as structural and parametric identifiability. As a result, given a particular water resource system and a certain scenario of climate change, different combinations of climate/downscaling/hydrological models may result in very different estimates of future water availability. Moreover, using the 'cascade of models approach', limited insights into the water resource system response to potential hydrological changes in the flow regime are obtained. We argue that there is merit in an alternative approach in which the vulnerability in water resource system response to a feasible range of future inflows is evaluated. We develop a stochastic reconstruction framework that generates a large ensemble of perturbed flow series at the local scale to represent a range of potential flow responses to climate change. This approach is generic and can provide insight into critical thresholds beyond which changes in the natural streamflow regime can initiate stress in the system. It can also provide the basis for assessment of specific realizations of future scenarios, which can be located on a vulnerability map. The methodology is applied to the existing water resource system of the South Saskatchewan river in southern Alberta, Canada, to explore the system's vulnerability to potential changes in the streamflow regime. By the use of a two- parameter representation of regime change (i.e. the shift in the timing of the annual peak as well as the shift in the annual flow volume), system vulnerability is visualized in a 2D vulnerability map. Our study shows that the water resource system in southern Alberta is vulnerable to the expected decrease in annual flow volume, particularly when combined with an earlier annual peak. Under such conditions, adaptation will be required to return the system to a feasible operational mode and sustain the apportionment commitments to the downstream province of Saskatchewan.

Strategy generator for optimal xenon oscillation control: Based on a new concept of axial offsets  

International Nuclear Information System (INIS)

Recently a new concept for controlling xenon oscillations has been used to optimize the control procedure for stabilizing an oscillation. The concept is based on two additional newly defined axial offsets, AOi and AOx together with the conventional axial offset AOp of axial power distribution. However, as the AOs are evaluated on line, it is impossible to predict the behavior of the AOs in advance. In order to overcome this situation a small auxiliary program has been developed. This program can generate the transients of the three AOs for the free running xenon oscillation. Then the user can input the most favorable conditions to eliminate the xenon oscillation such as total control hours, final AOp or time interval of the control rod movement. And an optimum search for the given final conditions is performed. The program can be used as a tool for a scoping study, the result of which can be obtained in a short time and also very easily

Mapping acoustic emissions from hydraulic fracture treatments using coherent array processing: Concept  

Energy Technology Data Exchange (ETDEWEB)

Hydraulic fracturing is a widely-used well completion technique for enhancing the recovery of gas and oil in low-permeability formations. Hydraulic fracturing consists of pumping fluids into a well under high pressure (1000--5000 psi) to wedge-open and extend a fracture into the producing formation. The fracture acts as a conduit for gas and oil to flow back to the well, significantly increasing communication with larger volumes of the producing formation. A considerable amount of research has been conducted on the use of acoustic (microseismic) emission to delineate fracture growth. The use of transient signals to map the location of discrete sites of emission along fractures has been the focus of most research on methods for delineating fractures. These methods depend upon timing the arrival of compressional (P) or shear (S) waves from discrete fracturing events at one or more clamped geophones in the treatment well or in adjacent monitoring wells. Using a propagation model, the arrival times are used to estimate the distance from each sensor to the fracturing event. Coherent processing methods appear to have sufficient resolution in the 75 to 200 Hz band to delineate the extent of fractures induced by hydraulic fracturing. The medium velocity structure must be known with a 10% accuracy or better and no major discontinuities should be undetected. For best results, the receiving array must be positioned directly opposite the perforations (same depths) at a horizontal range of 200 to 400 feet from the region to be imaged. Sources of acoustic emission may be detectable down to a single-sensor SNR of 0.25 or somewhat less. These conclusions are limited by the assumptions of this study: good coupling to the formation, acoustic propagation, and accurate knowledge of the velocity structure.

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

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Emerging eHealth tools could facilitate the delivery of comprehensive care in time-constrained clinical settings. One such tool is interactive computer-assisted health-risk assessments (HRA, which may improve provider-patient communication at the point of care, particularly for psychosocial health concerns, which remain under-detected in clinical encounters. The research team explored the perspectives of healthcare providers representing a variety of disciplines (physicians, nurses, social workers, allied staff regarding the factors required for implementation of an interactive HRA on psychosocial health. Methods The research team employed a semi-qualitative participatory method known as Concept Mapping, which involved three distinct phases. First, in face-to-face and online brainstorming sessions, participants responded to an open-ended central question: “What factors should be in place within your clinical setting to support an effective computer-assisted screening tool for psychosocial risks?” The brainstormed items were consolidated by the research team. Then, in face-to-face and online sorting sessions, participants grouped the items thematically as ‘it made sense to them’. Participants also rated each item on a 5-point scale for its ‘importance’ and ‘action feasibility’ over the ensuing six month period. The sorted and rated data was analyzed using multidimensional scaling and hierarchical cluster analyses which produced visual maps. In the third and final phase, the face-to-face Interpretation sessions, the concept maps were discussed and illuminated by participants collectively. Results Overall, 54 providers participated (emergency care 48%; primary care 52%. Participants brainstormed 196 items thought to be necessary for the implementation of an interactive HRA emphasizing psychosocial health. These were consolidated by the research team into 85 items. After sorting and rating, cluster analysis revealed a concept map with a seven-cluster solution: 1 the HRA’s equitable availability; 2 the HRA’s ease of use and appropriateness; 3 the content of the HRA survey; 4 patient confidentiality and choice; 5 patient comfort through humanistic touch; 6 professional development, care and workload; and 7 clinical management protocol. Drawing insight from the theoretical lens of Sociotechnical theory, the seven clusters of factors required for HRA implementation could be read as belonging to three overarching aspects : Technical (cluster 1, 2 and 3, Social-Patient (cluster 4 and 5, and Social-Provider (cluster 6 and 7. Participants rated every one of the clusters as important, with mean scores from 4.0 to 4.5. Their scores for feasibility were somewhat lower, ranging from 3.4 to. 4.3. Comparing the scores for importance and feasibility, a significant difference was found for one cluster from each region (cluster 2, 5, 6. The cluster on professional development, care and workload was perceived as especially challenging in emergency department settings, and possible reasons were discussed in the interpretation sessions. Conclusion A number of intertwined multilevel factors emerged as important for the implementation of a computer-assisted, interactive HRA with a focus on psychosocial health. Future developments in this area could benefit from systems thinking and insights from theoretical perspectives, such as sociotechnical system theory for joint optimization and responsible autonomy, with emphasis on both the technical and social aspects of HRA implementation.

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

Directory of Open Access Journals (Sweden)

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

Nanocrystals of medium soluble actives--novel concept for improved dermal delivery and production strategy.  

Science.gov (United States)

After use in oral pharmaceutical products, nanocrystals are meanwhile applied to improve the dermal penetration of cosmetic actives (e.g. rutin, hesperidin) and of drugs. By now, nanocrystals are only dermally applied made from poorly soluble actives. The novel concept is to formulate nanocrystals also from medium soluble actives, and to apply a dermal formulation containing additionally nanocrystals. The nanocrystals should act as fast dissolving depot, increase saturation solubility and especially accumulate in the hair follicles, to further increase skin penetration. Caffeine was used as model compound with relevance to market products, and a particular process was developed for the production of caffeine nanocrystals to overcome the supersaturation related effect of crystal growth and fiber formation - typical with medium soluble compounds. It is based on low energy milling (pearl milling) in combination with low dielectric constant dispersion media (water-ethanol or ethanol-propylene glycol mixtures) and optimal stabilizers. Most successful was Carbopol(®) 981 (e.g. 20% caffeine in ethanol-propylene glycol 3:7 with 2% Carbopol, w/w). Nanocrystals with varied sizes can now be produced in a controlled process e.g. 660 nm (optimal for hair follicle accumulation) to 250 nm (optimal for fast dissolution). The short term test proved stability over 2 months of the present formulation being sufficient to perform in vivo testing of the novel concept. PMID:24813782

Domestic water and sanitation as water security: monitoring, concepts and strategy.  

Science.gov (United States)

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

Combotherapy and current concepts as well as future strategies for the treatment of Alzheimer's disease  

Directory of Open Access Journals (Sweden)

Full Text Available Ling-Yun Fan,1,2 Ming-Jang Chiu2–4 1Department of Neurology, En Chu Kong Hospital, 2Department of Neurology, College of Medicine, Graduate Institute of Brain and Mind Sciences, 3Graduate Institute of Psychology, 4Graduate Institute of Biomedical Engineering and Bioinformatics, National Taiwan University Hospital, Taipei, Taiwan Abstract: It has been estimated that 35.6 million people globally had dementia in 2010 and the prevalence of dementia has been predicted to double every 20 years. Thus, 115.4 million people may be living with dementia in 2050. Alzheimer's disease (AD is the leading cause of dementia and is present in 60%–70% of people with dementia. Unfortunately, there are few approved drugs that can alleviate the cognitive or behavioral symptoms of AD dementia. Recent studies have revealed that pathophysiological changes related to AD occur decades before the appearance of clinical symptoms of dementia. This extended preclinical phase of AD provides a critical chance for disease-modifying agents to halt or delay the relentless process of AD. Although several trials targeting various pathological processes are ongoing, the examination of the combined use of different approaches to combat AD seems warranted. In this article, we will review current therapies, future strategies, and ongoing clinical trials for the treatment of AD with a special focus on combination therapies. Furthermore, preventive strategies for cognitively normal subjects in the presymptomatic stages of AD will also be addressed. In this review, we discuss current hypotheses of the disease process. In the decades since the approval of cholinesterase inhibitors, no new drug has ultimately demonstrated clear success in clinical trials. Given the difficulties that have been encountered in attempts to identify a single drug that can treat AD, we must pursue effective multi-target strategies, ie, combination therapies. The combination of cholinesterase inhibitors and memantine is considered well tolerated and safe, and this combination benefits patients with moderate-to-severe AD. In contrast, with the exception of adjuvant therapies of conventional drugs, combinations of different disease-modifying agents with different mechanisms may have promising synergic effects and benefit cognition, behavior, and daily living function. Keywords: disease-modifying agent, combination therapy, Alzheimer's disease

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

Energy Technology Data Exchange (ETDEWEB)

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

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

International Nuclear Information System (INIS)

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

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

Science.gov (United States)

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

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

International Nuclear Information System (INIS)

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

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

Directory of Open Access Journals (Sweden)

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

Digital soil mapping: strategy for data pre-processing Mapa digital de solos: estratégias para processamento de dados  

Directory of Open Access Journals (Sweden)

Full Text Available The region of greatest variability on soil maps is along the edge of their polygons, causing disagreement among pedologists about the appropriate description of soil classes at these locations. The objective of this work was to propose a strategy for data pre-processing applied to digital soil mapping (DSM. Soil polygons on a training map were shrunk by 100 and 160 m. This strategy prevented the use of covariates located near the edge of the soil classes for the Decision Tree (DT models. Three DT models derived from eight predictive covariates, related to relief and organism factors sampled on the original polygons of a soil map and on polygons shrunk by 100 and 160 m were used to predict soil classes. The DT model derived from observations 160 m away from the edge of the polygons on the original map is less complex and has a better predictive performance.Mapas de solos têm na borda dos polígonos a região de maior variabilidade, o que leva os pedólogos a divergir quanto ao delineamento das classes de solos nesses locais. O objetivo deste estudo foi propor uma estratégia de pré-processamento de dados aplicada ao mapeamento digital de solos. Polígonos de solos em um mapa de treinamento foram deslocados para seu interior em 100 e 160 m. Essa estratégia possibilitou que covariáveis localizadas próximas à borda das classes de solos não fossem utilizadas na geração dos modelos de Árvore de Decisão (AD. Três ADs geradas a partir de oito covariáveis preditoras, ligadas aos fatores relevo e organismos, amostradas nos polígonos originais de um mapa de solos e em polígonos deslocados em 100 e 160 m para o seu interior, foram utilizadas para predizer classes de solos. O modelo de AD a partir de observações distantes 160 m da borda dos polígonos no mapa original é menos complexo e tem melhor desempenho preditivo.

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

International Nuclear Information System (INIS)

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

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

International Nuclear Information System (INIS)

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

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

DEFF Research Database (Denmark)

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

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

Science.gov (United States)

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

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

International Nuclear Information System (INIS)

The overall purpose of the project was to make a survey of the changes in the Swedish nuclear power plants over the last five years. There is a risk that nuclear power companies after a deregulation will focus especially on reducing operation and maintenance costs and that the changes could have a negative effect on the reactor safety. The task has involved summarising the actual changes, describing the present situation, the need for future development and the differences between the plants as well as identifying possible reactor safety related risks. The survey has been carried out in a broad perspective, studying the changes in equipment, maintenance strategies and the work situation of the staff. Three case studies were carried out at the Swedish nuclear power plants. Documentation from the companies has been analysed and a selection of in total 27 'informed' employees in different positions have been interviewed in total. The project also included a fourth case study concerning railway traffic. This branch of business is interesting because of its longer experience on a deregulated and competitive market. Conclusions concerning the companies individually as well as similarities and differences between them are presented in this report. Results: There have been more changes both in strategy and organisation in the last five years than during the preceding 5-10-year-period and the pace has been relatively rapid. The deregulation of the electricity market was implemented January 1997 and became the main motive force for the changes. The staffing has been reduced or unchanged and the work demands have increased. The maintenance skills have been redistributed within the organisation. New methods and equipment, i.e. RCM, and programmable systems make increased demands for analytical and theoretical competence. In the short term, job satisfaction and motivation have in some cases been negatively influenced by the new organisation forms, according to several of the interviewed. The results indicate, in accordance with other research results, that rationalisations and changes must be combined with work development and the participation of the employees to be successful. Outsourcing has been used for some activities. All the companies have established a joint maintenance department for their units. The companies have been moving towards lean organization which has increased the work load of the staff. Therefore more planning is required to get a optimal resource allocation, to avoid problems at work peaks. All the plants have abandoned a downright customer-supplier relation for the benefit of one competent maintenance supplier with a comprehensive view. As a result the contractual undertaking of the maintenance department towards the production units is made on a long term basis. The new maintenance strategy is based on status controls for condition based maintenance and on riskbased analysing methods. There are modern computer-based maintenance systems at all the plants. Computer-based instruments are used direct in the production line where they require a competence shift in the staff. Positive effects that appeared in the interviews are better possibilities for experience feed back and methods development, access to a wider and larger competence and a joint working method. The results show that there are already some positive effects and there are more to be expected. But it is also clear that these effects have neither come as easily nor as fast as was expected. Possible negative effects: there is a risk that the staffing might be too scarce, especially in work peaks, e.g. unexpected shutdowns. A high work load and much overtime work mean greater strain on the staff. Problems with job satisfaction and motivation, chiefly after the change to a matrix organisation. Uncertainties as to responsibility and roles in the new organisation. The practical competence might 'disappear' in the present competence shift focusing on analytical, computer based methods. The difficulties of risk based methods are several: they might not cor

Digital soil mapping: strategy for data pre-processing / Mapa digital de solos: estratégias para processamento de dados  

Scientific Electronic Library Online (English)

Full Text Available SciELO Brazil | Language: English Abstract in portuguese Mapas de solos têm na borda dos polígonos a região de maior variabilidade, o que leva os pedólogos a divergir quanto ao delineamento das classes de solos nesses locais. O objetivo deste estudo foi propor uma estratégia de pré-processamento de dados aplicada ao mapeamento digital de solos. Polígonos [...] de solos em um mapa de treinamento foram deslocados para seu interior em 100 e 160 m. Essa estratégia possibilitou que covariáveis localizadas próximas à borda das classes de solos não fossem utilizadas na geração dos modelos de Árvore de Decisão (AD). Três ADs geradas a partir de oito covariáveis preditoras, ligadas aos fatores relevo e organismos, amostradas nos polígonos originais de um mapa de solos e em polígonos deslocados em 100 e 160 m para o seu interior, foram utilizadas para predizer classes de solos. O modelo de AD a partir de observações distantes 160 m da borda dos polígonos no mapa original é menos complexo e tem melhor desempenho preditivo. Abstract in english The region of greatest variability on soil maps is along the edge of their polygons, causing disagreement among pedologists about the appropriate description of soil classes at these locations. The objective of this work was to propose a strategy for data pre-processing applied to digital soil mappi [...] ng (DSM). Soil polygons on a training map were shrunk by 100 and 160 m. This strategy prevented the use of covariates located near the edge of the soil classes for the Decision Tree (DT) models. Three DT models derived from eight predictive covariates, related to relief and organism factors sampled on the original polygons of a soil map and on polygons shrunk by 100 and 160 m were used to predict soil classes. The DT model derived from observations 160 m away from the edge of the polygons on the original map is less complex and has a better predictive performance.

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

Directory of Open Access Journals (Sweden)

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

Mapping the categories of the Swedish primary health care version of ICD-10 to SNOMED CT concepts: Rule development and intercoder reliability in a mapping trial  

Directory of Open Access Journals (Sweden)

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

The effects of collaborative concept mapping on the achievement, science self-efficacy and attitude toward science of female eighth-grade students  

Science.gov (United States)

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

Gone but not Forgotten? The Use of Airborne Laser Mapping in the Recovery Strategy for the Ivory-billed Woodpecker  

Science.gov (United States)

The reappearance of the ivory-billed woodpecker in 2004, long-thought to be extinct, has created considerable controversy. Millions of dollars have been spent in the subsequent search to provide confirmation of the sightings, and thus validate what would be one of the great avian rediscoveries of our time. Recent searches for the woodpecker in the Cache and White River National Wildlife Refuges in Arkansas by ground-based teams have failed to locate it. However, the area is immense, with many locations difficult to access on foot. Thus, there is the need for near-term habitat monitoring at the local scale to guide immediate search efforts, and near- and long-term landscape scale characterization and assessment, both to guide further search efforts and to delineate suitable potential habitat should a population be found. A joint research effort by the University of Maryland, the US Fish and Wildlife Service, NASA, and the US Geological Survey was initiated early this year with the goal of using airborne and satellite remote sensing for habitat characterization and monitoring consistent with the ivory-billed woodpecker recovery strategy. A centerpiece of this effort is the use of lidar remote sensing to map management factors such as canopy cover, basal area, tree stocking, height and biomass, all of which are difficult to retrieve by any other means. In June, the Laser Vegetation Imaging Sensor (LVIS) was used to map over 1 million hectares of potential habitat. In this paper we discuss our mapping efforts with particular focus on how these data are used to make maps of forest management factors, and how these maps may then be combined to highlight areas of particularly suitable woodpecker habitat.

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

International Nuclear Information System (INIS)

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

A novel respiratory motion compensation strategy combining gated beam delivery and mean target position concept - A compromise between small safety margins and long duty cycles  

International Nuclear Information System (INIS)

Purpose: To evaluate a novel respiratory motion compensation strategy combining gated beam delivery with the mean target position (MTP) concept for pulmonary stereotactic body radiotherapy (SBRT). Materials and methods: Four motion compensation strategies were compared for 10 targets with motion amplitudes between 6 mm and 31 mm: the internal target volume concept (planITV); the MTP concept where safety margins were adapted based on 4D dose accumulation (planMTP); gated beam delivery without margins for motion compensation (plangated); a novel approach combining gating and the MTP concept (plangated and MTP). Results: For 5/10 targets with an average motion amplitude of 9 mm, the differences in the mean lung dose (MLD) between plangated and planMTP were gated and MTP. Despite significantly shorter duty cycles, plangated reduced the MLD by gated and MTP. The MLD was increased by 18% in planMTP compared to that of plangated and MTP. Conclusions: For pulmonary targets with motion amplitudes >10-15 mm, the combination of gating and the MTP concept allowed small safety margins with simultaneous long duty cycles.

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

Directory of Open Access Journals (Sweden)

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 conceptmapping as a teaching method to facilitate critical thinking by student nurses in nursing education. Recommendations are made.

Verpleegkundestudente word blootgestel aan ’n geweldige hoeveelheid inligting en leesmateriaal wat baie spesifiek, tegnies en nuut is vir die studente. Tensy verpleegkundeopvoeders ’n leeromgewing kan voorsien wat deur interaksie die bevordering van begrip bewerkstellig, kan studente inligting deur papegaaiwerk in hul korttermyngeheue stoor, eerder as om dit te assimileer – geen betekenisvolle leer sal dus plaasvind nie. Verpleegkundestudente moet die vermoë hê om die verband tussen aangeleerde feite, konsepte en beginsels en nuwe kennis te lê sodat hulle in die praktyk rasionale besluite kan maak (All & Havens 1997:1210, 1213. Hierdie artikel het ten doel om die aanwending van konsepkartering as 'n onderrigstrategie te beskryf, ten einde die kritiese denke van leerders in die verpleegkunde te fasiliteer. Die beskrywing van die aanwending van konsepkartering word vanuit die teoretiese raamwerke van konsepkartering en kritiese denke gedoen om die epistemologiese grondslag vir konsepkartering te voorsien (Facione 1990:6, 13. Gegrond op die verkenning en beskrywing van die teoretiese raamwerke, word vier fases vir die fasilitering van kritiese denke geformuleer deur middel van konsepkartering. Hierdie verkenning en beskrywing is gebaseer op die onderwysproses: die identifiseringsfase, die interaktiewe konstrueringsproses, die formuleringsfase en evalueringsfase. Die gevolgtrekking word gemaak dat die aanwending van hierdie fases verpleegopvoeders behulpsaam sal wees in die implementering van konsepkartering as 'n onderrigmetode om kritiese denke by leerling verpleërs te fasiliteer in verpleegkunde-onderwys.

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

International Nuclear Information System (INIS)

Today, the major component of the world's power consumption is based on natural gas and petroleum products. The major challenge for research and development of new energy sources is to find environmentally and economically acceptable ways to make a transition away from these increasingly scarce primary fuels. Technologies based on nuclear fission offer a promising solution. Reactor designs that capitalize on inherent safety characteristics are attractive choices for the further development of nuclear power. Such a system is the high temperature gas-cooled reactor (HTGR). Current research on the HTGR concept concentrates on a reactor with a pebble bed core. Analysis focuses on several areas. These include the following conceptual studies: 1. potential combinations of advanced fuel compositions and structural materials that improve performance characteristics of the pebble bed HTGR; 2. an advanced pebble bed HTGR design with a helium temperature elevated to >1300 K that provides the possibility of obtaining higher efficiency of the thermodynamic cycle; 3. prolonged operation of the pebble bed HTGR on a single fuel loading reaching high burnups. The results obtained from the listed foregoing studies are presented and discussed in this paper. As in all conventional reactors, during operation of the pebble bed, HTGR fissile material is being burned. This loss of fissile material in the fuel needs to be compensated for. Compensation of the fuel depletion can be performed by external actions, such as replacement or addition of new fuel, control rod motion, or internal conversion of fertile material into fissile material in the pebble bed HTGR core. The possibility of sustaining criticality during a long-term operation based on the mechanism of internal conversion has been demonstrated. The main idea of the present analysis consists of minimizing the external action required for the pebble bed HTGR toward prolonged operation on a single fuel loading. Flexibility of the HTGR fuel cycle and the possibility of achieving high fuel burnups in the HTGR core under conditions of safe reactor operation are the key conditions that make the pebble bed HTGR concept attractive as the basis for long-term energy development. They are also the major reasons why this concept has been chosen for the current studies. Efficient utilization of different forms and types of fuels is possible even in the same core. Uranium, plutonium, and mixed fuels in dicarbide and dioxide forms are studied as possible elements of fuel composition to be utilized as a long-term energy source. To improve the pebble bed HTGR behavior at elevated temperatures, refractory and chemically stable ZrC has been considered as an alternative to SiC. The current studies of the pebble bed HTGR concept are performed with SCALE 4.3 and MCNP 4A. SCALE 4.3 is a multipurpose computer code system that has modules for deterministic criticality and burnup calculations. Application of this code system allows accurate modeling of fuel depletion. As a result, fuel lifetime is evaluated for a particular combination of materials utilized. MCNP 4A is the code system for Monte Carlo modeling. The Monte Carlo method offers the possibility of taking into account all the details of the three-dimensional geometry of the real pebble bed core. The model of the pebble bed HTGR core takes into account the well-known double heterogeneity due to utilization of fuel pebbles and dispersion fuel. The methodology of realistic modeling for detailed descriptions of the pebble bed HTGR core developed earlier is applied to provide sufficient accuracy in both the Monte Carlo and deterministic calculations. Accuracy of all the models used in the deterministic calculations with SCALE is validated using the results of the MCNP calculations with the detailed three-dimensional model. The current analysis of the long-term energy source based on the pebble bed HTGR concept is aimed toward an inherent balance between the fuel material depletion and material conversion mentioned earlier. The studies concentrate on the pebb

Analysis of genomic admixture in Uyghur and its implication in mapping strategy.  

Science.gov (United States)

The Uyghur (UIG) population, settled in Xinjiang, China, is a population presenting a typical admixture of Eastern and Western anthropometric traits. We dissected its genomic structure at population level, individual level, and chromosome level by using 20,177 SNPs spanning nearly the entire chromosome 21. Our results showed that UIG was formed by two-way admixture, with 60% European ancestry and 40% East Asian ancestry. Overall linkage disequilibrium (LD) in UIG was similar to that in its parental populations represented in East Asia and Europe with regard to common alleles, and UIG manifested elevation of LD only within 500 kb and at a level of 0.1 mapping by admixture LD (MALD) is still applicable in the Uyghur population but approximately 10-fold AIMs are necessary for a whole-genome scan.

A BAC pooling strategy combined with PCR-based screenings in a large, highly repetitive genome enables integration of the maize genetic and physical maps  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Molecular markers serve three important functions in physical map assembly. First, they provide anchor points to genetic maps facilitating functional genomic studies. Second, they reduce the overlap required for BAC contig assembly from 80 to 50 percent. Finally, they validate assemblies based solely on BAC fingerprints. We employed a six-dimensional BAC pooling strategy in combination with a high-throughput PCR-based screening method to anchor the maize genetic and physical maps. Results A total of 110,592 maize BAC clones (~ 6x haploid genome equivalents were pooled into six different matrices, each containing 48 pools of BAC DNA. The quality of the BAC DNA pools and their utility for identifying BACs containing target genomic sequences was tested using 254 PCR-based STS markers. Five types of PCR-based STS markers were screened to assess potential uses for the BAC pools. An average of 4.68 BAC clones were identified per marker analyzed. These results were integrated with BAC fingerprint data generated by the Arizona Genomics Institute (AGI and the Arizona Genomics Computational Laboratory (AGCoL to assemble the BAC contigs using the FingerPrinted Contigs (FPC software and contribute to the construction and anchoring of the physical map. A total of 234 markers (92.5% anchored BAC contigs to their genetic map positions. The results can be viewed on the integrated map of maize 12. Conclusion This BAC pooling strategy is a rapid, cost effective method for genome assembly and anchoring. The requirement for six replicate positive amplifications makes this a robust method for use in large genomes with high amounts of repetitive DNA such as maize. This strategy can be used to physically map duplicate loci, provide order information for loci in a small genetic interval or with no genetic recombination, and loci with conflicting hybridization-based information.

Application of digital mapping technology to the display of hydrologic information; a proof-of-concept test in the Fox-Wolf River Basin, Wisconsin  

Science.gov (United States)

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

The cross-cultural study on the effect of the use of student-generated visualization as a study strategy for middle school science concept learning  

Science.gov (United States)

The researcher applied quantitative and qualitative approaches to determine first whether or not the use of student-generated visualization as a study strategy affects middle school students' understanding of textual materials on science topics. Secondly, the relative effectiveness of student-generated visualization on paper and on computers was explored. Thirdly, the differential impact of using visualization as a study strategy across Texan and Taiwanese cultures was investigated. Six intact science classes of 92 Texan 8th graders were randomly assigned to 3 treatment groups: the control group, the experimental/paper group, and the experimental/computer group. Further, 2 intact 8th grade science classes of 60 Taiwanese participants were randomly assigned to 2 treatment groups: the control group, and the experimental/paper group. Students in the control groups watched science-related videotapes that did not address visualization as a study strategy. The experimental/paper groups attended visualization workshops in which they learned how to visualize on paper in their regular classrooms; and the experimental/computer group attended the computer-based visualization workshop in which they learned how to visualize on computers in the computer lab. After the workshops, the control groups were given several science essays for unguided and independent study. The experimental/paper groups and the experimental/computer group were given the same science essays to study as were the control groups. However, they were also asked to use their learned visualization skills to create visual representations that showed interrelationships among concepts on paper or on computers during their study time. When the study time was over, students were given a science comprehension posttest to measure their understanding of the concepts in the texts. The results showed that student-generated visualization had a positive impact on both Texan and Taiwanese eighth graders' science concept learning, but it did not impact one cultural group more than the other. Visualization as a study strategy had positive effects regardless of whether students used paper or computers to generate their visualizations. Given the training in visualization, middle school students were able to generate visual representations that showed interrelationships among concepts to demonstrate their understanding.

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

DEFF Research Database (Denmark)

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

"Meaning" as a sociological concept: A review of the modeling, mapping, and simulation of the communication of knowledge and meaning  

CERN Document Server

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

Development and investigation of a semi-active polar planar haptic interface using the digital resistance map concept  

Science.gov (United States)

The growing demand for haptic technologies in recent years has motivated novel approaches in developing haptic interfaces and control algorithms. Semi-active haptic interfaces, in general, have the advantage of addressing safety concerns which adversely affect their active counterparts. This paper presents the development of a planar semi-active haptic interface using magnetorheological (MR) dampers. The ability of MR dampers to produce controllable resistance forces is the key reason for their utilization in the proposed haptic interface. The proposed planar semi-active haptic interface consists of linear and rotary MR dampers. Each of the MR dampers is modeled experimentally using the Bouc–Wen model. A haptic rendering algorithm called the digital resistance map (DRM) is also developed to control MR dampers. DRM is a high-fidelity haptic rendering algorithm, and proved to be effective to create comprehensive force feedback for operators. MATLAB/Simulink® is used for implementing several DRM scenarios for generating haptic enabled virtual environments. The experimental results demonstrate the effectiveness of the proposed haptic interface and rendering algorithm.

An intron capture strategy used to identify and map a lysyl oxidase-like gene on chromosome 9 in the mouse  

Energy Technology Data Exchange (ETDEWEB)

An intron capture strategy involving use of polymerase chain reaction was used to identify and map the mouse homologue of a human lysyl oxidase-like gene (LOXL). Oligonucleotides complementary to conserved domains within exons 4 and 5 of the human lysyl oxidase-like gene were used to amplify the corresponding segment from mouse genomic DNA. Sequencing of the resulting mouse DNA fragment of approximately 1 kb revealed that the exon sequences at the ends of the amplified fragment are highly homologous (90% nucleotide identity) to exons 4 and 5 of the human lysyl oxidase-like gene. An AluI restriction site polymorphism within intron 4 was used to map the mouse lysyl oxidase-like gene (Loxl) to mouse Chromosome 9 in a region that shares linkage conservation with human chromosome 15q24, to which the LOXL was recently mapped. 22 refs., 3 figs.

Mapping the gravity field in coastal areas: feasibility and interest of a new airborne planar gradiometer concept  

Science.gov (United States)

Satellite missions such as CHAMP, GRACE and GOCE have led to an unprecedented improvement of global gravity field models during the past decade. However, for many applications these global models are not sufficiently accurate when dealing with wavelengths shorter than 100 km. This is all the more true in areas where gravity data are scarce and uneven as for instance in the poorly covered land-sea transition area. We suggest here, in line with spatial gravity gradiometry, airborne gravity gradiometry as a convenient way to amplify the sensitivity to short wavelengths and to cover homogeneously coastal region. Moreover, the directionality of the gravity gradients gives new information on the geometry of the gravity field and therefore of the causative bodies. In this respect, we analyze here the performances of a new airborne electrostatic acceleration gradiometer, GREMLIT, which permits along with ancillary measurements to determine the horizontal gradients of the horizontal components of the gravitational field in the instrumental frame. GREMLIT is composed of a compact assembly of 4 planar electrostatic accelerometers inheriting from technologies developed by ONERA for spatial accelerometers. After an overview of the functionals of the gravity field that are of interest for coastal oceanography, passive navigation and hydrocarbon exploration, we present the corresponding required precision and resolution. Then, we investigate the influence of the different parameters of the survey, such as altitude or cross-track distance, on the resolution and precision of the final measurements. To do so, we design numerical simulations of airborne survey performed with GREMLIT and compute the total error budget on the gravity gradients. Based on this error analysis, we infer by a method of error propagation the uncertainty on the different functionals of the gravity potential used for each application. This finally enables us to conclude on the requirements for a high resolution mapping of the gravity field in coastal areas.

Concepts, strategies and potentials using hypo-g and other features of the space environment for commercialization using higher plants  

Science.gov (United States)

Opportunities for releasing, capturing, constructing and/or fixing the differential expressions or response potentials of the higher plant genome in the hypo-g environment for commercialization are explored. General strategies include improved plant-growing, crop and forestry production systems which conserve soil, water, labor and energy resources, and nutritional partitioning and mobilization of nutrients and synthates. Tissue and cell culture techniques of commercial potential include the growing and manipulation of cultured plant cells in vitro in a bioreactor to produce biologicals and secondary plants of economic value. The facilitation of plant breeding, the cloning of specific pathogen-free materials, the elimination of growing point or apex viruses, and the increase of plant yield are other O-g applications. The space environment may be advantageous in somatic embryogenesis, the culture of alkaloids, and the development of completely new crop plant germ plasm.

Substrate mapping strategies for successful ablation of ventricular tachycardia: A review / Técnicas de mapeo y ablación del sustrato arrítmico en pacientes con taquicardia ventricular  

Scientific Electronic Library Online (English)

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

Ciclização intramolecular: uma estratégia promissora no desenvolvimento de pró-fármacos Intramolecular cyclization: a promising strategy in the prodrug conception  

Directory of Open Access Journals (Sweden)

Full Text Available Muitos fármacos estão associados a vários efeitos adversos e limitada biodisponibilidade. A resolução destes problemas continua sendo um alvo importante para a comunidade científica. O desenvolvimento de pró-fármacos que conduzam a uma liberação controlada in vivo é um caminho atrativo para resolver estes problemas. Um pró-fármaco clássico é molécula inativa, em que o princípio ativo é ligado covalentemente a uma unidade transportadora, de modo que o fármaco pode ser liberado através de uma reação química ou enzimática. Um sistema novo e interessante de pró-fármaco, que tem sido apresentado para fármacos possuidores de grupos amino, álcool e tiol, é aquele no qual o princípio ativo é liberado através de uma ciclização intramolecular. Neste caso, o processo de ciclização, dependendo da cadeia da unidade transportadora e do próprio fármaco, pode controlar a velocidade de liberação do princípio ativo. Desta forma, este trabalho apresenta uma revisão do desenvolvimento de pró-fármacos baseados na liberação do princípio ativo através de uma ciclização intramolecular.Many drugs used for the treatment of common diseases are associated with various adverse effects and limited bioavailability. The suppression of such problems continues to be a very important target for scientists. The development of prodrugs for controlled release in vivo is an attractive way to overcome these problems. Classical in prodrug is an inactive molecule which the parent drug is covalently bonded to a carrier unit, and which can liberate the drug through chemical or enzymatic pathways. A new and interesting prodrug system for amine, alcohol, and thiol drugs takes advantage of several easy intramolecular cyclization reactions. So, the cyclization process can control the release rate of the parent drug. In this paper is a review about the prodrug strategies based on intramolecular cyclization reactions is presented.

The NASA Innovations in Climate Education Project: 'Instructional Strategies for Expanding Climate Change Concepts within Readng/Literacy Skills  

Science.gov (United States)

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

Nova abordagem para verificar como os alunos articulam diferentes materiais instrucionais utilizando mapas conceituais / New approach to investigate how students articulate different instructional materials using concept maps

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

Change point analysis of travel routes reveals novel insights into foraging strategies and cognitive maps of wild baboons.  

Science.gov (United States)

Efficient space use is a critical challenge for animals relying on stationary resources. It is often difficult with purely observational methods to gain unambiguous insight into any ability of primates to manage and process spatial information. Investigating the visible signs of the decision processes underlying space use often leaves open important issues. We applied the change point test [Byrne et al. (2009). Anim Behav 77: 619-631], a statistical tool to objectively determine change points (CPs) in animal travel paths, to investigate to what degree directional changes in our study group's (Papio ursinus) dry season ranging were associated with important resources and prominent landmarks. One-third of directional changes were associated with fruit feeding, 1/3 with traveling, and 1/3 with dry matter feeding, travel feeding and with drinking. When directional changes were associated with traveling, the subsequent directional changes were likely to result in fruit feeding. Fruit feeding mostly occurred at the apex of the day journeys, while drinking, dry matter feeding, and travel feeding often occurred along straight travel segments. The majority of directional changes did not occur in clusters at distinctive locations, but at distances of more than 120?m apart from each other, many of them along prominent landmarks. We conclude that the CPs do not represent nodes or route bends of a network map. Rather, they represent (1) locations where the decision to turn back to their sleeping site was taken, and (2) locations next to important landmarks (changes of slope, car tracks) where slight adjustment of a movement direction was possible. We found no evidence for a Euclidean map and discuss our findings in the light of a network map representation of space. PMID:23946104

Greatest emphasis is placed on optical time-of- flight (OTOF) chemical detection when the measurements are taken along the length of a single continuous extended-length 'distributed' sensing element. The attractive features of such distributed sensing element fabricated by immobilization of chemically sensitive reagents directly into the original cladding of a conventional plastic-clad silica (PCS) optical fiber are demonstrated. Several signal generation and processing methods are devised to address the requirements for spatially resolved chemical sensing. These requirements include high signal levels, a fairly uniform detection limit over the length of the sensing fiber, measurements with dynamically quenched fluorophores, and high spatial resolution. Applications of OTOF distributed chemical sensors for spatially resolved analyte mapping for environmental and process applications are discussed.

Anteil Stigma-assoziierter Themen im Psychiatrie-Konzept von Medizinstudierenden in der Einführung in die klinische Medizin: Eine Mind-Map Studie [Proportion of stigma-associated items in medical students' psychiatric concepts at the beginning of the clinical phase of medical education: a mind-map study  

Directory of Open Access Journals (Sweden)

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

Negativ belegte Stigma-Themen waren wesentlich häufiger als positive Einstellungen zum Thema Stigma und betrafen meist Zwangsmaßnahmen. Schlussfolgerung: Insgesamt zeigte sich, dass Mind-Maps einfach eingesetzt und ausgewertet werden können, um Krankheitskonzepte und assoziierte Begriffe zu einem Fachgebiet im Sinne der konstruktivistischen Lerntheorie zu explorieren, ohne vordefinierte Fragebögen zu verwenden.

Interrater reliability of the mind map assessment rubric in a cohort of medical students  

Directory of Open Access Journals (Sweden)

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

Mimotope mapping as a complementary strategy to define allergen IgE-epitopes: peach Pru p 3 allergen as a model.  

Science.gov (United States)

Lipid transfer proteins (LTPs) are the major allergens of Rosaceae fruits in the Mediterranean area. Pru p 3, the LTP and major allergen of peach, is a suitable model for studying food allergy and amino acid sequences related with its IgE-binding capacity. In this work, we sought to map IgE mimotopes on the structure of Pru p 3, using the combination of a random peptide phage display library and a three-dimensional modelling approach. Pru p 3-specific IgE was purified from 2 different pools of sera from peach allergic patients grouped by symptoms (OAS-pool or SYS-pool), and used for screening of a random dodecapeptide phage display library. Positive clones were further confirmed by ELISA assays testing individual sera from each pool. Three-dimensional modelling allowed location of mimotopes based on analysis of electrostatic properties and solvent exposure of the Pru p 3 surface. Twenty-one phage clones were selected using Pru p 3-specific IgE, 9 of which were chosen using OAS-specific IgE while the other 12 were selected with systemic-specific IgE. Peptide alignments revealed consensus sequences for each pool: L37 R39 T40 P42 D43 R44 A46 P70 S76 P78 Y79 for OAS-IgE, and N35 N36 L37 R39 T40 D43 A46 S76 I77 P78 for systemic-IgE. These 2 consensus sequences were mapped on the same surface of Pru p 3, corresponding to the helix 2-loop-helix 3 region and part of the non-structured C-terminal coil. Thus, 2 relevant conformational IgE-binding regions of Pru p 3 were identified using a random peptide phage display library. Mimotopes can be used to study the interaction between allergens and IgE, and to accelerate the process to design new vaccines and new immunotherapy strategies. PMID:18242709

Illness representations: mapping the experience of lupus.  

Science.gov (United States)

Lupus, a chronic illness that mainly affects women, presents numerous challenges to health professionals due to the unpredictable nature of the disease course. To provide appropriate educational interventions for those living with lupus, health educators must develop methods best suited to individuals' current mental representations of their illness. A cognitive mapping strategy was used in this study to ascertain the patients' own perceptions of living with lupus. The participants (N = 20) identified 192 unduplicated concepts in their maps, which were ultimately collapsed into 12 major categories. The results of this study indicate that, although diagnosed with the same illness, the women presented with different mental representations of their illness. Consequently, cognitive mapping could serve as a useful tool to initiate tailored educational interventions for those living with lupus. PMID:10435229

Value adding management: A concept and a case  

DEFF Research Database (Denmark)

Purpose: To develop a management concept that can assist facilities managers in implementing value adding strategies and practices. The FM Value Map has been developed to analyse and demonstrate the different ways FM can add value. However, there is a need to develop management tools that can be used more directly and proactively by facilities managers to implement adding value strategies and practices. Methodology: The development of the concept of Value Adding Management is based on the management model for FM included in the European FM standards, recent theories on added value of FM and real estate and the related concept of Value Management from building projects. The chapter outlines a preliminary theoretical based management concept, which is investigated, tested and discussed based on a case study of LEGO. Findings: The case study provides a clear example of a company that actual practice value adding management. It underlines the importance of stakeholder and relationship management as part of adding value. The case study confirms the relevance of the basic concept of Value Adding Management. Practical implications: The concept of Value Adding Management is expected to increase the awareness of the impacts and strategic importance of FM for organisations and can be a practical tool for facilities managers in implementing value adding strategies and practices. Research limitations: The concept has only been validated in a single case study; the generality should be validated with case studies from other types of organisation. Originality/value: The concept is new and represents a promising way to strengthen the strategic management of FM.

Public health benefits of reducing air pollution in Shanghai: a proof-of-concept methodology with application to BenMAP.  

Science.gov (United States)

In recent years, levels of particulate matter (PM) air pollution in China have been relatively high, exceeding China's Class II standards in many cities and impacting public health. This analysis takes Chinese health impact functions and underlying health incidence, applies 2010-2012 modeled and monitored PM air quality data, and estimates avoided cases of mortality and morbidity in Shanghai, assuming achievement of China's Class II air quality standards. In Shanghai, the estimated avoided all cause mortality due to PM10 ranged from 13 to 55 cases per day and from 300 to 800 cases per year. The estimated avoided impact on hospital admissions due to PM10 ranged from 230 cases to 580 cases per day and from 5400 to 7900 per year. The estimated avoided impact on all cause mortality due to PM2.5 ranged from 6 to 26 cases per day and from 39 to 1400 per year. The estimated impact on all cause mortality of a year exposure to an annual or monthly mean PM2.5 concentration ranged from 180 to 3500 per year. In Shanghai, the avoided cases of all cause mortality had an estimated monetary value ranging from 170 million yuan (1 US dollar=4.2 yuan Purchasing Power Parity) to 1200 million yuan. Avoided hospital admissions had an estimated value from 20 to 43 million yuan. Avoided emergency department visits had an estimated value from 5.6 million to 15 million yuan. Avoided outpatient visits had an estimated value from 21 million to 31 million yuan. In this analysis, available data were adequate to estimate avoided health impacts and assign monetary value. Sufficient supporting documentation was available to construct and format data sets for use in the United States Environmental Protection Agency's health and environmental assessment model, known as the Environmental Benefits Mapping and Analysis Program - Community Edition ("BenMAP-CE").

Advancement of the climate dual strategy. New concepts for a globally effective climate protection; Weiterentwicklung der baden-wuerttembergischen Klimadoppelstrategie. Neue Konzepte fuer einen global wirksamen Klimaschutz  

Energy Technology Data Exchange (ETDEWEB)

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

Evaluation of pesticide monitoring strategies in agricultural streams based on the toxic-unit concept - Experiences from long-term measurements.  

Science.gov (United States)

The European Water Framework Directive requires surface water bodies to have a good chemical and ecological status. Although relatively few pesticides are included in the list of priority pollutants, they pose, due to their intrinsic biological activity, a significant risk for the integrity of aquatic ecosystems. In this context, the pesticide (up to 128 pesticides including some transformation products) exposure pattern in four agricultural streams and two rivers was determined from 2002 to 2011 under the umbrella of the Swedish national monitoring program employing time-proportional and grab sampling strategies, respectively. After transforming the measured pesticide concentrations into toxic units, the European Uniform Principles for algae (chronic), invertebrates and fish (both acute), which are partly employed as benchmark for pesticide regulation, were only occasionally (pesticide monitoring strongly depends on its overall purpose. If the long-term exposure pattern is of concern a time-proportional composite sampling strategy is recommended, while for an assessment of peak exposures a flow-event-triggered high-resolution sampling strategy is superior.

Mapping out Map Libraries  

Directory of Open Access Journals (Sweden)

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

A novel approach to mapping load transfer from the plantar surface of the foot to the walls of the total contact cast: a proof of concept study  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Total contact casting is regarded as the gold standard treatment for plantar foot ulcers. Load transfer from the plantar surface of the foot to the walls of the total contact cast has previously been assessed indirectly. The aim of this proof of concept study was to determine the feasibility of a new method to directly measure the load between the cast wall and the lower leg interface using capacitance sensors. Methods Plantar load was measured with pedar® sensor insoles and cast wall load with pliance® sensor strips as participants (n=2 walked along a 9 m walkway at 0.4±0.04 m/sec. The relative force (% on the cast wall was calculated by dividing the mean cast wall force (N per step by the mean plantar force (N per step in the shoe-cast condition. Results The combined average measured load per step upon the walls of the TCC equated to 23-34% of the average plantar load on the opposite foot. The highest areas of load on the lower leg were located at the posterior margin of the lateral malleolus and at the anterior ankle/extensor retinaculum. Conclusions These direct measurements of cast wall load are similar to previous indirect assessment of load transfer (30-36% to the cast walls. This new methodology may provide a more comprehensive understanding of the mechanism of load transfer from the plantar surface of the foot to the cast walls of the total contact cast.

The Japanese approach to developing clay-based repository concepts An example of design studies for the assessment of sealing strategies  

Science.gov (United States)

The H12 repository concept for vitrified high-level radioactive waste was developed based on a multi-barrier system, with the emphasis on robust engineered barrier performance to ensure its feasibility for a wide range of geological conditions typically observed in Japan. The decision to use a volunteer siting process requires maximum flexibility of the repository concept to allow it to be adapted to potential sites and hence a wide range of variants of the basic H12 repository design has been developed. In order to evaluate the feasibility and applicability of different repository options to specific siting environments, NUMO has established a set of “design factors” which classify the aspects that need to be considered when evaluating the pros and cons of different repository options. The buffer in the repository concepts is clay-based. An Na-type bentonite from Japan is used as the reference material for all clay-based repository components (buffer, backfill, clay plug, etc.). The characteristics of this bentonite (thermal, mechanical, chemical, hydraulic) have been examined with consideration of various practical constraints (limitation on the repository footprint, the influence of saline water, the interaction of hyperalkaline leachates, practical working environment, etc.). Clay-based seals, which close off the tunnels after emplacement of the engineered barrier system (EBS), may also be key components for assessment of the performance of the repository. Full analyses considering all engineered barrier components (buffer, backfill, clay plug, concrete lining, tunnel, concrete plug) that may be used in a repository will be an essential future task. As a first step towards this goal, a numerical analysis focusing on hydraulic behaviour at the intersections of the disposal tunnels and the main tunnel is presented to illustrate how the design requirements of clay-based seals can be determined.

Proof of the Concept to Use a Malignant B Cell Line Drug Screen Strategy for Identification and Weight of Melphalan Resistance Genes in Multiple Myeloma  

Science.gov (United States)

In a conceptual study of drug resistance we have used a preclinical model of malignant B-cell lines by combining drug induced growth inhibition and gene expression profiling. In the current report a melphalan resistance profile of 19 genes were weighted by microarray data from the MRC Myeloma IX trial and time to progression following high dose melphalan, to generate an individual melphalan resistance index. The resistance index was subsequently validated in the HOVON65/GMMG-HD4 trial data set to prove the concept. Biologically, the assigned resistance indices were differentially distributed among translocations and cyclin D expression classes. Clinically, the 25% most melphalan resistant, the intermediate 50% and the 25% most sensitive patients had a median progression free survival of 18, 32 and 28 months, respectively (log-rank P-value ?=?0.05). Furthermore, the median overall survival was 45 months for the resistant group and not reached for the intermediate and sensitive groups (log-rank P-value ?=?0.003) following 38 months median observation. In a multivariate analysis, correcting for age, sex and ISS-staging, we found a high resistance index to be an independent variable associated with inferior progression free survival and overall survival. This study provides clinical proof of concept to use in vitro drug screen for identification of melphalan resistance gene signatures for future functional analysis.

Fuzzy Cognitive Maps and Neutrosophic Cognitive Maps  

CERN Multimedia

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

Which Map's the Best Map for Antarctica?  

Science.gov (United States)

With Antarctica as the focus, this week-long unit provides an in-depth look at the advantages and disadvantages of different map types. Throughout the unit, students collect their findings in a portfolio. The comprehensive curriculum materials contain teacher tools, which include individually downloadable readings, detailed daily breakdowns of tasks, teacher strategies for using the activities, a portfolio grading sheet, a project rubric sheet, and additional readings. There is an online activity in which students first review how latitude and longitude are used in map creation and then are introduced to the different types of map projections. There are two hands-on activities in which students examine how globes, Mercator maps, and polar map projections are used, and create their own map projections using soda bottles.

Concepts Are Beliefs About Essences  

Digital Repository Infrastructure Vision for European Research (DRIVER)

The most promising strategy to understand (sentential) narrow contents or (subsentential) concepts seems to be to conceive them as primary intensions or diagonals within the epistemologically reinterpreted character theory of Kaplan. However, this strategy seems to founder either at Block's dilemma between a too syntacticist or too holistic understanding of narrow contents and concepts or at Schiffer's problem that the character theory depends on functional role semantics without adding anyth...

Estrategias de decisión en sistemas dinámicos: aplicando mapas cognitivos difusos aplicación a un ejemplo socio - económico / Decision strategies in dynamic systems using fuzzy cognitive maps: Application to a socio - economic example  

Scientific Electronic Library Online (English)

Full Text Available SciELO Brazil | Language: Spanish Abstract in spanish Las situaciones que abarcan el contexto en que el ser humano desarrolla sus tareas cotidianas son extremadamente complejas y dinámicas. En cada campo, el análisis de las variables que componen el sistema objeto de estudio puede simplificarse si se lo concibe compuesto como un conjunto de conceptos d [...] onde un cambio en cada uno de ellos provocará cambios en los restantes. Cuando se trata de analizar la problemática de un área particular, la representación de los conceptos en forma de un mapa permite sintetizar la información aislando los principales conceptos que están vinculados en el problema. En estos casos los Mapas Cognitivos Difusos (MCD) logran sintetizar gran parte de la información presente. Además con esta técnica es posible seguir la evolución de los conceptos hasta un estado de equilibrio y por lo tanto permiten estudiar la dinámica que lleva el pasaje de un estado a otro determinado en la situación que se analiza. En este trabajo se expone la técnica de construcción y análisis de Mapas Cognitivos Difusos a través de un ejemplo de aplicación a la economía. El objetivo consiste en presentar una metodología de trabajo apoyada en los MCD que permite analizar la evolución y el impacto que provoca en el sistema el cambio en el valor de uno o varios conceptos intervinientes.

In the analysis of a particular problem, the representation of concepts in the form of a map helps to synthesize information detecting the main concepts that are linked to the problem. In these cases, Fuzzy Cognitive Maps (FCM) are able to synthesize much of this information. Also with this technique is possible to follow the evolution of the concepts to a state of equilibrium and therefore allow us to study the dynamics that takes the passage from one state to another given the situation under review. This paper describes the construction and analysis of the Fuzzy Cognitive Maps technique through an economy application example. The aim is to present a methodology supported by the FCM to analyze the evolution and impact on the system causing by the change in the value of one or more concepts involved.

Building online brand perceptual map.  

Science.gov (United States)

Many companies have launched their products or services online as a new business focus, but only a few of them have survived the competition and made profits. The most important key to an online business's success is to create "brand value" for the customers. Although the concept of online brand has been discussed in previous studies, there is no empirical study on the measurement of online branding. As Web 2.0 emerges to be critical to online branding, the purpose of this study was to measure Taiwan's major Web sites with a number of personality traits to build a perceptual map for online brands. A pretest identified 10 most representative online brand perceptions. The results of the correspondence analysis showed five groups in the perceptual map. This study provided a practical view of the associations and similarities among online brands for potential alliance or branding strategies. The findings also suggested that brand perceptions can be used with identified consumer needs and behaviors to better position online services. The brand perception map in the study also contributed to a better understanding of the online brands in Taiwan. PMID:18785819

Specifying role interaction in concept languages  

Digital Repository Infrastructure Vision for European Research (DRIVER)

The KL-ONE concept language provides role-value maps (RVMs) as a concept forming operator that compares sets of role fillers. This is a useful means to specify structural properties of concepts. Recently, it has been shown that concept languages providing RVMs together with some other common concept-forming operators induce an undecidable subsumption problem. Thus, RVMs have been restricted to chainings of functional roles as, for example, in CLASSIC. Although this restricted RVM is still a u...

Detecting mutations in the dihydrochalcon 2'- glycosyltransferase and Kunitz protease inhibitor gene amongst a segregating apple population as a SNPS-based genome mapping strategy  

International Nuclear Information System (INIS)

Fire blight, caused by the bacteria Erwinia amylovora, is a major production constraint for fruit trees of the family Rosaceae such as apples for which resistance to the disease is thought to be polygenic. We have in this study sought to develop a molecular genetic linkage core map; to identify molecular markers linked to the genes involved in fire blight resistance in apples; and to map the genes, dihydrochalcon 2'-glycosyltransferase and Kunitz protease inhibitor, which are thought to be involved in resistance to this disease. A population of 140 individuals being the progeny of the cross between Malus robusta 5 (wild, disease resistant) and Idared (cultivated, susceptible) that segregated for the incidence of disease symptoms were screened using molecular markers and the segregation data used to create male and female linkage coremaps. For the Idared parent, the core-map constructed from the segregation of 130 AFLPs, 60 SSRs and 1 SCAR was made up of 20 linkage groups, spanned 1082 cM and covered 94 % of the genome. The Malus robusta 5 core-map with 19 linkage groups was anchored by 150 AFLPs, 60 SSRs and 1 SCAR, spanned 1033 cM and covered 75 % of the genome. Additionally, we report the localization of a QTL on linkage group 3 of the resistant parent that explained 84.1% of the phenotypic variation. Using the SNP technology we developed, the dihydrochalcon2'-glycosyltransferase and Kunitz protease inhibitor genes implicated in resistance to this disease were mapped to linkage group 11 and linkage group 3 respectively of the Malus robusta 5 core-map. The implications of the results are discussed. (author)

Conceitos, percepções e estratégias para conservação de uma Estação Ecológica da Caatinga nordestina por populações do seu entorno / Concepts, perceptions and strategies for conservation of an Ecological Station of Caatinga by communities in the vicinity  

Directory of Open Access Journals (Sweden)

Full Text Available The loss of Earth´s biodiversity is a major concern for the international scientific community andmegadiverse countries like Brazil are paramount for discussions about the overall situation of theplanet. The Caatinga biome is probably one of the most threatened in Brazil and the implementation ofConservation Units (CU represents a measure for protecting its natural resources and biodiversity.The Station Ecological of Seridó (ESEC-Serido is one of the few CU in the Caatinga of Rio Grande doNorte State (NE Brazil and interacts with several neighboring communities and settlements. Howeverthe ESEC does not integrate environmental perception feedback from the local communities in itsmanagement plan. Considering this, the present articles aims at identifying the perceptions and conceptsof such communities regarding environmental issues and biodiversity as well as indicate strategies toimprove the administration of this CU. In order to achieve these goals, a review of the specializedliterature was carried out and a research tool based on Environmental Perception was developed in theform of structured interviews applied to the persons from communities neighboring the ESEC. Theseinterviews were later processed through content analysis. The concepts and perceptions obtained throughthis analysis show that the people from the environs are aware of the main problems faced by ESECSeridó,as well as the strategies to address them.

Integrating Software Architecture Concepts into the MDA Platform with UML Profile  

Directory of Open Access Journals (Sweden)

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

Methods and applications for visualization of SNOMED CT concept sets.  

Science.gov (United States)

Inconsistent use of SNOMED CT concepts may reduce comparability of information in health information systems. Terminology implementation should be approached by common strategies for navigating and selecting proper concepts. This study aims to explore ways of illustrating common pathways and ancestors of particular sets of concepts, to support consistent use of SNOMED CT and also assess potential applications for such visualizations. The open source prototype presented is an interactive web-based re-implementation of the terminology visualization tool TermViz that provides an overview of concepts and their hierarchical relations. It provides terminological features such as interactively rearranging graphs, fetching more concept nodes, highlighting least common parents and shared pathways in merged graphs etc. Four teams of three to four people used the prototype to complete a terminology mapping task and then, in focus group interviews, discussed the user experience and potential future tool usage. Potential purposes discussed included SNOMED CT search and training, consistent selection of concepts and content management. The evaluation indicated that the tool may be useful in many contexts especially if integrated with existing systems, and that the graph layout needs further tuning and development. PMID:24734129
