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

Science.gov (United States)

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

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.

Concept mapping: an educational strategy to improve graduate nurses' critical thinking skills during a hospital orientation program.  

Science.gov (United States)

Novice graduate nurses (GNs) are often deficient in the critical thinking skills needed to assess and handle patient problems and life-threatening situations. Concept mapping is an effective teaching strategy for developing critical thinking and clinical decision-making skills. This small descriptive comparison study was undertaken to determine whether concept mapping improved critical thinking skills in GNs during a hospital orientation program. Schuster's (2002) Concept Map Care Plan Evaluation Tool was adapted to measure GNs' critical thinking in concept maps based on case studies at the beginning and end of orientation. A paired t test was computed on pre- and post-mean map scores of 14.071 and 16.428, respectively. Concept mapping was a valuable teaching and evaluation strategy for this group that could be used by nursing educators to improve critical thinking and identify and correct areas of theoretical and clinical deficiency.

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

Directory of Open Access Journals (Sweden)

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

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

Science.gov (United States)

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

Creating Heliophysics Concept Maps  

Science.gov (United States)

The Center for Science Education at University of California Berkeley's Space Sciences Laboratory is creating concept maps for Heliophysics and would like to get input from scientists. The purpose of this effort is 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. These maps are meant to tie into the AAAS Project 2061 Benchmarks for Scientific Literacy and National Science Education Standards. It is hoped that the results of this effort will be useful for curriculum designers developing Heliophysics-related curriculum materials and classroom teachers using Heliophysics materials. The need for concept maps was identified as a result of product analysis undertaken by the NASA Heliophysics Forum Team. The NASA Science Education and Public Outreach Forums have as two of their goals to improve the characterization of the contents of the Science Mission Directorate and Public Outreach (SMD E/PO) portfolio (Objective 2.1) and assist SMD in addressing gaps in the portfolio of SMD E/PO products and project activities (Objective 2.2). An important part of this effort is receiving feedback from solar scientists regarding the inclusion of key concepts and their progression in the maps. This session will introduce the draft concept maps and elicit feedback from scientists.

Designing concepts and strategies  

DEFF Research Database (Denmark)

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

Using concept maps in perioperative education.  

Science.gov (United States)

Critical thinking and clinical decision making are essential components of the knowledge and skills acquired in the perioperative education process. Although traditional didactic teaching methods remain predominant teaching strategies in perioperative nursing education, programs should include a variety of methods and tools to enhance learning of a considerable amount of complex material. Concept mapping is an active teaching strategy that can be used in nursing education to facilitate the development of critical thinking and decision-making skills. A concept map is a tool consisting of a main idea, subconcepts, and cross-links that organizes knowledge by showing relationships between concepts. Different types of maps can be used to present different types of learning material, depending on the focus of the lesson. Complex knowledge (eg, perioperative technology) can be better learned and retained when the brain works to organize information in a hierarchical framework and the information is built up with interacting concepts.

Concept mapping for learners of all ages  

Directory of Open Access Journals (Sweden)

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

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.

Cmapanalysis: an extensible concept map analysis tool  

Directory of Open Access Journals (Sweden)

Full Text Available Concept maps are used extensively as an assessment tool, and the literature is abundant with studies on the use of concept maps for assessment and on the assessment of concept maps. The assessment of concept maps can be an arduous process, in particular when assessing a large number of maps. CmapAnalysis is a software tool that facilitates performing various analysis measures on a collection of concept maps. A set of measures that consider size, quality and structure properties of the maps are included. The program is designed to be extensible, allowing users to add their own measures. The program is not intended to replace the individual evaluation of concept maps by teachers and instructors, as it does not capable of “understanding” the content of the maps. It is aimed at researchers who are looking for more general trends and measures across a large number of maps, and who can extend it with their own measures. The output of CmapAnalysis is an Excel spreadsheet that can be further analyzed.

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

A Concept Hierarchy Based Ontology Mapping Approach  

Science.gov (United States)

Ontology mapping is one of the most important tasks for ontology interoperability and its main aim is to find semantic relationships between entities (i.e. concept, attribute, and relation) of two ontologies. However, most of the current methods only consider one to one (1:1) mappings. In this paper we propose a new approach (CHM: Concept Hierarchy based Mapping approach) which can find simple (1:1) mappings and complex (m:1 or 1:m) mappings simultaneously. First, we propose a new method to represent the concept names of entities. This method is based on the hierarchical structure of an ontology such that each concept name of entity in the ontology is included in a set. The parent-child relationship in the hierarchical structure of an ontology is then extended as a set-inclusion relationship between the sets for the parent and the child. Second, we compute the similarities between entities based on the new representation of entities in ontologies. Third, after generating the mapping candidates, we select the best mapping result for each source entity. We design a new algorithm based on the Apriori algorithm for selecting the mapping results. Finally, we obtain simple (1:1) and complex (m:1 or 1:m) mappings. Our experimental results and comparisons with related work indicate that utilizing this method in dealing with ontology mapping is a promising way to improve the overall mapping results.

On the role of concept mapping assessments in today's constructivist classroom  

Science.gov (United States)

The purpose of this study was to explore the use of concept map assessments in freshman level general chemistry courses. Two strategies were employed in this study. The first strategy involved the creation of a web based concept mapping program capable of scoring concept maps drawn by students. The second strategy involved comparing different methods of scoring concept maps. Students enrolled in web based general chemistry course drew concept maps using the web based Concept Map Assessment Tool, CMAT. The reliability of the automated scoring in the CMAT program was tested by scoring the concept maps created in the CMAT program by hand. The results of the study indicated that scoring concept maps by hand was the same as the automated scoring of concept maps in the CMAT program. Two characteristics of concept maps serve as the basis for scoring methods. The relational character of a concept map is defined as the correctness of the propositions in the concept map. The structural character of a concept map is defined as the key features of the map, such as branches, long chains or intersecting points. The scoring method used in the CMAT program scores the relational aspects of a concept map. In this study, a second relational scoring method was used to score the concept maps drawn by students using the CMAT program, and the two sets of scores were compared. A novel structural scoring method, the Structural Complexity Index (SCI), was developed compared to the relational scoring approach of the CMAT program. The results of this study found the two relational scoring methods to score concept maps similarly under certain conditions. The SCI was found to produce a different score for concept maps than the relational scoring method employed by CMAT.

Developing nurses' critical thinking skills with concept mapping.  

Science.gov (United States)

Observations and research in educational and practice settings suggest new nurses are not using critical thinking skills. Teaching strategies traditionally focused on linear modes of thinking--no longer as helpful in today's complex and crisis-driven contexts. Concept mapping has promise of promoting higher levels of thinking and may develop critical thinking--and decision-making skills--in less time and without intensive oversight by staff instructors. A case example is used to demonstrate the design of a concept map. PMID:15586090

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.

Complementary and conventional medicine: a concept map  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Despite the substantive literature from survey research that has accumulated on complementary and alternative medicine (CAM in the United States and elsewhere, very little research has been done to assess conceptual domains that CAM and conventional providers would emphasize in CAM survey studies. The objective of this study is to describe and interpret the results of concept mapping with conventional and CAM practitioners from a variety of backgrounds on the topic of CAM. Methods Concept mapping, including free sorts, ratings, and multidimensional scaling was used to organize conceptual domains relevant to CAM into a visual "cluster map." The panel consisted of CAM providers, conventional providers, and university faculty, and was convened to help formulate conceptual domains to guide the development of a CAM survey for use with United States military veterans. Results Eight conceptual clusters were identified: 1 Self-assessment, Self-care, and Quality of Life; 2 Health Status, Health Behaviors; 3 Self-assessment of Health; 4 Practical/Economic/ Environmental Concerns; 5 Needs Assessment; 6 CAM vs. Conventional Medicine; 7 Knowledge of CAM; and 8 Experience with CAM. The clusters suggest panelists saw interactions between CAM and conventional medicine as a critical component of the current medical landscape. Conclusions Concept mapping provided insight into how CAM and conventional providers view the domain of health care, and was shown to be a useful tool in the formulation of CAM-related conceptual domains.

Directory of Open Access Journals (Sweden)

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

Examination of Elementary Teachers’ Views about Concept Maps  

Directory of Open Access Journals (Sweden)

Full Text Available

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.

Concept maps and canonical models in neuropsychiatry.  

Science.gov (United States)

Most bioscientists engage in informal modelling in their research and explicitly document this activity's results in diagrams or "concept maps". While canonical modelling approaches such as Biochemical Systems Theory (BST) immediately allow the construction of a corresponding system of equations, the problem of determining appropriate parameter values remains. Goel et al. introduced Concept Map Modelling (CMM) as a framework to address this problem through an interactive dialogue between experimenters and modellers. The CMM dialogue extracts the experimenters' implicit knowledge about dynamical behaviour of the parts of the system being modelled in form of rough sketches and verbal statements, e.g. value ranges. These are then used as inputs for parameter and initial value estimates for the symbolic canonical model based on the diagram. Canonical models have the big advantage that a great variety of parameter estimation methods have been developed for them in recent years. The paper discusses the suitability of this approach for neuropsychiatry using recent work of Qi et al. on a canonical model of presynaptic dopamine metabolism. Due to the complexity of systems encountered in neuropsychiatry, hybrid models are often used to complement the canonical models discussed here. PMID:19434549

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.

Linking human factors to corporate strategy with cognitive mapping techniques.  

Science.gov (United States)

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

Image inpainting strategy for Kinect depth maps  

Science.gov (United States)

The great advantage of Microsoft Kinect makes the depth acquisition real-time and inexpensive. But the depth maps directly obtained with the Microsoft Kinect device have absent regions and holes caused by optical factors. The noisy depth maps affect lots of complex tasks in computer vision. In order to improve the quality of the depth maps, this paper presents an efficient image inpainting strategy which is based on watershed segmentation and region merging framework of the corresponding color images. The primitive regions produced by watershed transform are merged into lager regions according to color similarity and edge among regions. Finally, mean filter operator to the adjacent pixels is used to fill up missing depth values and deblocking filter is applied for smoothing depth maps.

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.

The Impact of Concept Mapping on EFL Learners' Critical Thinking Ability  

Directory of Open Access Journals (Sweden)

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

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 for virtual rehabilitation and training of the blind.  

Science.gov (United States)

Concept mapping is a technique that allows for the strengthening of the learning process, based on graphic representations of the learner's mental schemes. However, due to its graphic nature, it cannot be utilized by learners with visual disabilities. In response to this limitation we implemented a study that involves the design of AudiodMC, an audio-based, virtual environment for concept mapping designed for use by blind users and aimed at virtual training and rehabilitation. We analyzed the stages involved in the design of AudiodMC from a user-centered design perspective, considering user involvement and usability testing. These include an observation stage to learn how blind learners construct conceptual maps using concrete materials, a design stage to design of a software tool that aids blind users in creating concept maps, and a cognitive evaluation stage using AudiodMC. We also present the results of a study implemented in order to determine the impact of the use of this software on the development of essential skills for concept mapping (association, classification, categorization, sorting and summarizing). The results point to a high level of user acceptance, having identified key sound characteristics that help blind learners to learn concept codification and selection skills. The use of AudiodMC also allowed for the effective development of the skills under review in our research, thus facilitating meaningful learning. PMID:19775989

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.

Global Ice Sheet Mapping Observatory Concept  

Science.gov (United States)

We describe field experiments designed to test a spaceborne-radar system-concept envisioned to measure the spatial reflectivity and the 3-dimensional surface and basal topography of terrestrial ice sheets and to determine the physical properties of the glacier bed. We conducted our experiments during May 2006, September 2007 and July 2008 in Northern and Central Greenland. We operated 150 and 450 MHz radars which we installed on a P-3 and Twin Otter aircraft. We operated at altitudes up to 6800 m above mean sea level and as low as 500 m above the ice sheet surface. We used 2 transmitting antennas and 6-8 receiving antennas so as to be able to acquire nadir data as well as to be able to form interferometric pairs with different baseline combinations. We collected data over different glacial regimes including over the North East Ice Stream which is suspected to be underlain by water and where we detected strong echoes. Our results indicate that without substantial post processing, surface and volume clutter obscures a strong basal echo in the interior ice sheet at 450 MHz and to a lesser degree at 150 MHz when the sensor is flown several kilometers above the ice sheet surface. Comparisons between the strong radar echo at the ice stream location with calibration data acquired over the ocean enable us to estimate attenuation through the ice at both frequencies. We use the data to test several clutter rejection schemes including interferogram filtering and multiaperture beam formation. We successfully tested both approaches and show how the interferogram filtering technique also allows for simultaneous separation of signals from the left and right side of the aircraft. We use the separation scheme to compute the three-dimensional subglacial topography along several swaths each of which is up to 3 km wide. We find that the basal topography of our northwestern Greenland study areas consists of gently undulating hills of about 5 km wavelength that are occasionally cross-cut by narrow valleys.

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 – a method that may supplement the engineer’s quantitative sound measurements and the landscape architect’s qualitative descriptors this article outlines a few approaches to a theory of acoustic territoriality and suggests alternative ways of mapping, analyzing and planning urban sonic environments.

The Facebook influence model: a concept mapping approach.  

Science.gov (United States)

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

The longitudinal effect of concept map teaching on critical thinking of nursing students.  

Science.gov (United States)

Concept map is a useful cognitive tool for enhancing a student's critical thinking by encouraging students to process information deeply for understanding. However, there is limited understanding of longitudinal effects of concept map teaching on students' critical thinking. The purpose of the study was to investigate the growth and the other factors influencing the development of critical thinking in response to concept map as an interventional strategy for nursing students in a two-year registered nurse baccalaureate program. The study was a quasi-experimental and longitudinal follow-up design. A convenience sample was drawn from a university in central Taiwan. Data were collected at different time points at the beginning of each semester using structured questionnaires including Critical Thinking Scale and Approaches to Learning and Studying. The intervention of concept map teaching was given at the second semester in the Medical-Surgical Nursing course. The results of the findings revealed student started with a mean critical thinking score of 41.32 and decreased at a rate of 0.42 over time, although not significant. After controlling for individual characteristics, the final model revealed that the experimental group gained a higher critical thinking score across time than the control group. The best predictive variables of initial status in critical thinking were without clinical experience and a higher pre-test score. The growth in critical thinking was predicted best by a lower pre-test score, and lower scores on surface approach and organized study. Our study suggested that concept map is a useful teaching strategy to enhance student critical thinking. PMID:22795871

Mapping Changes in Science Teachers' Content Knowledge: Concept Maps and Authentic Professional Development  

Science.gov (United States)

Two studies were conducted to examine content knowledge changes following 2 weeks of professional development that included scientific research with university scientists. Engaging teachers in scientific research is considered to be an effective way of encouraging knowledge of both inquiry pedagogy and content knowledge. We used concept maps with two cohorts of teachers to assess changes in science teacher knowledge. In study 1, 34 teachers developed pre- and post-concept maps in one of the nine different content areas. A repeated measures analysis of six quantitative scores showed statistically significant increases in knowledge representation. Quantitative and qualitative scoring methods indicate that concept maps are effective for assessing teacher knowledge gains from professional development. Study 2 replicated the results with 24 teachers and provided further information about how knowledge changes.

Proteogenomics: concepts, applications and computational strategies.  

Science.gov (United States)

Proteogenomics is an area of research at the interface of proteomics and genomics. In this approach, customized protein sequence databases generated using genomic and transcriptomic information are used to help identify novel peptides (not present in reference protein sequence databases) from mass spectrometry-based proteomic data; in turn, the proteomic data can be used to provide protein-level evidence of gene expression and to help refine gene models. In recent years, owing to the emergence of new sequencing technologies such as RNA-seq and dramatic improvements in the depth and throughput of mass spectrometry-based proteomics, the pace of proteogenomic research has greatly accelerated. Here I review the current state of proteogenomic methods and applications, including computational strategies for building and using customized protein sequence databases. I also draw attention to the challenge of false positive identifications in proteogenomics and provide guidelines for analyzing the data and reporting the results of proteogenomic studies.

Mapping What They Know: Concept Maps as an Effective Tool for Assessing Students’ Systems Thinking  

Directory of Open Access Journals (Sweden)

Full Text Available In 2006 anew biology curriculum called “Human Biology: Emphasizing the Role of Homeostasis” was introduced into the Israeli high school system. Complex systems like those that make up the human body have become increasingly important as a focus of high school education. This study examines the effectiveness of the concept map as a assessment tool for students’ systems thinking, a tool that provides researchers with a detailed picture of the systems thinking development taking place within individual students. The content of the students’ concept maps was translated into information about students’ system thinking using the Systems Thinking Hierarchy (STH model, a model in which system thinking is categorized according to eight hierarchical characteristics or abilities. The goal was to use the maps to characterize Israeli high school students’ understanding of the body’s systemic nature. To do this, we identified the extent to which the students understand three central elements of systems, namely hierarchy, homeostasis, and dynamism, and then analyzed this understanding according to its place within the hierarchical stages of the STH model. The extensive qualitative data analysis of 48 concept maps made by 11th grade biology majors suggest that the strength of the concept map is in its ability to describe the first two levels of system thinking (analysis and synthesis. However, it proved less successful in eliciting evidence of the third and highest level, particularly of students’ understanding of patterns, of homeostasis and their capacity for temporal thinking.

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

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

Strategy-oriented display concept to assist severe accident management  

International Nuclear Information System (INIS)

The Critical Function Monitoring System (CFMS) is a typical Safety Parameter Display System (SPDS) to assist the operation of Korean Standard Nuclear Power Plants during normal and emergency operation, and SPDS for severe accident is being developed in Korea. When the existing CFMS is used under a severe accident situation, some problems are expected from: (1) different design basis, i.e. prevention of core melt vs. protection of radiation release to environment, (2) different parameters for decision-making, and (3) different domain and depth of information to restore the plant. To resolve the above problems, a concept, 'Strategy-Oriented Information Display' concept, for displaying information for severe accident management is developed in this paper. Whereas the existing SPDS structure is based on the critical safety function, the developed concept is based on the severe accident management strategy. The display for each strategy includes the plant parameters to check the status of plant and component with the logical or graphical views necessary for executing the strategy. As the application of the proposed concept, KAERI is developing a display system, the prototype severe accident SPDS, Severe Accident Management Display System (SAMDIS), to assist plant personnel for executing Korean Severe Accident Management Guidelines. CFMS is developed for a general display suitable to all situations with various displays. On the contrary, SAMDIS provides all the relevant information on one screen based on the proposed concept. The SAMDIS screen shows more extensive area than CFMS and thus plant personnel can recognize the overall plant status at a glance. This concept is quite effective when used with severe accident management guidelines because of the relatively macroscopic characteristics of a severe accident management strategy. (author)

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.

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.

The effect of concept mapping on clinical decision making skills of ICU nurses  

Directory of Open Access Journals (Sweden)

Full Text Available Introduction: Concept mapping is an innovative tool that would help hospital educators and nurses to promote their knowledge and clinical decision making skills. The aim of this study was to investigate the effect of concept mapping on clinical decision making skills of nurses working in the intensive care unit (ICU. Methods: The quasi-experimental, non-equivalent control group, pretest-posttest design was conducted among baccalaureate nurses working in an intensive care unit. Forty two nurses were recruited and data gathering was performed through a self-administered questionnaire. Statistical analysis was conducted by SPSS software package version 16.0. Results: Despite the significant difference between the mean pre-, post- and retention test scores (P<0.001, there was no significant correlation between these results and the nurses’ gender. A negative significant association was found between age and improved post test scores (P=0.02. Work experience had a significant positive effect on post test score improvement (P<0.001. Conclusion: This study revealed that the concept mapping strategy had a significant effect on the clinical decision making skills of nurses. However, further research on a larger sample size is recommended to confirm the results.

Mapping low-level image features to semantic concepts  

Science.gov (United States)

Humans tend to use high-level semantic concepts when querying and browsing multimedia databases; there is thus, a need for systems that extract these concepts and make available annotations for the multimedia data. The system presented in this paper satisfies this need by automatically generating semantic concepts for images form their low-level visual features. The proposed system is built in two stages. First, an adaptation of k-means clustering using a non- Euclidean similarity metric is applied to discover the natural patterns of the data in the low-level feature space; the cluster prototype is designed to summarize the cluster in a manner that is suited for quick human comprehension of its components. Second, statistics measuring the variation within each cluster are used to derive a set of mappings between the most significant low-level features and the most frequent keywords of the corresponding cluster. The set of the derived rules could be used further to capture the semantic content and index new untagged images added to the image database. The attachment of semantic concepts to images will also give the system the advantage of handling queries expressed in terms of keywords and thus, it reduces the semantic gap between the user's conceptualization of a query and the query that is actually specified to the system. While the suggested scheme works with any kind of low-level features, our implementation and description of the system is centered on the use of image color information. Experiments using a 21 00 image database are presented to show the efficacy of the proposed system.

Handling knowledge via Concept Maps: a space weather use case  

Science.gov (United States)

Concept Maps (Cmaps) are powerful means for knowledge coding in graphical form. As flexible software tools exist to manipulate the knowledge embedded in Cmaps in machine-readable form, such complex entities are suitable candidates not only for the representation of ontologies and semantics in Virtual Observatory (VO) architectures, but also for knowledge handling and knowledge discovery. In this work, we present a use case relevant to space weather applications and we elaborate on its possible implementation and adavanced use in Semantic Virtual Observatories dedicated to Sun-Earth Connections. This analysis was carried out in the framework of the Electronic Geophysical Year (eGY) and represents an achievement synergized by the eGY Virtual Observatories Working Group.

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.

A genealogical map of the concept of habit.  

Science.gov (United States)

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

Concept Mapping as an Instrument for Evaluating an Instruction Unit on Holography (Concept Maps als Evaluierungsinstrumente einer Unterrichtseinheit zur Holographie)  

CERN Document Server

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

Mediated learning experience and concept maps: a pedagogical tool for achieving meaningful learning in medical physiology students  

Science.gov (United States)

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

Inception horizon concept as a basis for sinkhole hazard mapping  

Science.gov (United States)

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

Elaboration of A Process for Mapping between Ontology Concepts and Objects Model Concepts  

Directory of Open Access Journals (Sweden)

Full Text Available The principal idea of the framework in this paper is to use ontologies to convert a problem domain text description into an object model. The object model of a system consists of objects, identified from the text description and structural linkages corresponding to existing or established relationships. The ontologies provide metadata schemas, offering a controlled vocabulary of concepts. At the center of both object models and ontologies are objects within a given problem domain. The difference is that while the object model should contain explicitly shown structural dependencies between objects in a system, including their properties, relationships, events and processes, the ontologies are based on related terms only. On the other hand, the object model refers to the collections of concepts used to describe the generic characteristics of objects in object-oriented languages. Because ontology is accepted as a formal, explicit specification of a shared conceptualization, we can naturally link ontologies with object models, which represent a system-oriented map of related objects, described as Abstract Data Types (ADTs. This paper addresses ontologies as a basis of a complete methodology for object modeling, including available tools, particularly CORPORUM OntoExtract and VisualText, which can help the conversion process. This paper describes how the developers can use this framework and implement it on the base of an illustrative example.

A new strategy for developing Vs30 maps  

Science.gov (United States)

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

The power and benefits of concept mapping: measuring use, usefulness, ease of use, and satisfaction  

Science.gov (United States)

The power and benefits of concept mapping rest in four arenas: enabling shared understanding, the inclusion of affect, the balance of power, and client involvement. Concept mapping theory and research indicate concept maps (1) are appropriate tools to assist with communication, (2) are easy to use, and (3) are seen as beneficial by their users. An experiment was conducted to test these assertions and analyze the power and benefits of concept mapping using a typical business consulting scenario involving 16 groups of two individuals. The results were analyzed via empirical hypothesis testing and protocol analyses, and indicate an overall support of the theory and prior research and additional support of new measures of usefulness, ease of use, and satisfaction by both parties. A more thorough understanding of concept mapping is gained and available to future practitioners and researchers.

The concept map as a research and evaluation tool: Further evidence of validity  

Science.gov (United States)

This study sought further evidence of the concurrent validity of concept mapping as a research and evaluation tool in science education. Specifically, the study examined the extent to which differences exist in the concept maps of advanced college biology majors (N = 25) and beginning nonmajors (N = 25) in the domain of mammals. Furthermore, it explored whether these differences are reflected in the way subjects assign class membership as revealed in a card sorting task. The results indicate that concept maps of biology majors are structurally more complex than those of nonmajors and that differences in the structural complexity and organizational patterns depicted in concept maps are reflected in the underlying dimensions used to assign class membership. Together, these findings suggest that the concept map provides a theoretically powerful and psychometrically sound tool for assessing conceptual change in experimental and classroom settings.

Concept mapping and network analysis: an analytic approach to measure ties among constructs.  

Science.gov (United States)

Group concept mapping is a mixed-methods approach that helps a group visually represent its ideas on a topic of interest through a series of related maps. The maps and additional graphics are useful for planning, evaluation and theory development. Group concept maps are typically described, interpreted and utilized through points, clusters and distances, and the implications of these features in understanding how constructs relate to one another. This paper focuses on the application of network analysis to group concept mapping to quantify the strength and directionality of relationships among clusters. The authors outline the steps of this analysis, and illustrate its practical use through an organizational strategic planning example. Additional benefits of this analysis to evaluation projects are also discussed, supporting the overall utility of this supplemental technique to the standard concept mapping methodology.

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.

Using Concept Mapping to Develop a Logic Model for the Prevention Research Centers Program  

Directory of Open Access Journals (Sweden)

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

The Contribution of Conceptual Change Texts Accompanied by Concept Mapping to Eleventh-Grade Students Understanding of Cellular Respiration Concepts  

Science.gov (United States)

The present study conducted to investigate the contribution of conceptual change texts, accompanied by concept mapping instruction to eleventh-grade students' understanding of cellular respiration concepts, and their retention of this understanding. Cellular respiration concepts test was developed as a result of examination of related literature and interviews with teachers regarding their observations of students' difficulties. The test was administrated as pre-test, post-test, and delayed post-test to a total of 70 eleventh-grade students in two classes of the same high school in an urban area, taught by the same teacher. The experimental group was a class of 34 students who received conceptual change texts accompanied by concept mapping instruction. A class of 36 students comprised the control group who received traditional instruction. Besides treatment, previous understanding and logical thinking ability were other independent variables involved in this study. The results showed that logical thinking, treatment, previous understanding of cellular respiration concepts each made a statistically significant contribution to the variation in students' understanding of cellular respiration concepts. The result also showed that conceptual change texts accompanied by concept mapping instruction was significantly better than traditional instruction in retention of this understanding.

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

Energy Technology Data Exchange (ETDEWEB)

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

A strategy for QTL fine-mapping using a dense SNP map  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Dense marker maps require efficient statistical methods for QTL fine mapping that work fast and efficiently with a large number of markers. In this study, the simulated dataset for the XIIth QTLMAS workshop was analyzed using a QTL fine mapping set of tools. Methods The QTL fine-mapping strategy was based on the use of statistical methods combining linkage and linkage disequilibrium analysis. Variance component based linkage analysis provided confidence intervals for the QTL. Within these regions, two additional analyses combining both linkage analysis and linkage disequilibrium information were applied. The first method estimated identity-by-descent probabilities among base haplotypes that were used to group them in different clusters. The second method constructed haplotype groups based on identity-by-state probabilities. Results Two QTL explaining 9.4 and 3.3% of the genetic variance were found with high significance on chromosome 1 at positions 19.5 and 76.6 cM. On chromosome 2, two QTL were also detected at positions 26.0 and 53.2 explaining respectively 9.0 and 7.8 of total genetic variance. The QTL detected on chromosome 3 at position 11.9 cM (5% of variance was less important. The QTL with the highest effect (37% of variance was detected on chromosome 4 at position 3.1 cM and another QTL (13.6% of variance was detected on chromosome 5 at position 93.9 cM. Conclusion The proposed strategy for fine-mapping of QTL combining linkage and linkage disequilibrium analysis allowed detecting the most important QTL with an additive effect in a short period but it should be extended in the future in order to fine-map linked and epistatic QTL.

A Self-Study of the Use of Concept Mapping to Assess NOS  

Directory of Open Access Journals (Sweden)

Full Text Available We undertook a self study to examine and develop our pedagogical content knowledge for teaching the nature of science. We explored two different uses of concept mapping to assess preservice teachers? ideas about the nature of science (NOS in an elementary science methods course. The class was divided into two groups. Group 1 was provided with aspects of NOS as starter concepts for their maps, while Group 2 was asked to develop their own concepts related to “science”. We found that being given the NOS aspects constrained Group 1?s ability to expand the connection of the main concept with other related words. On the other hand, Group 2 had difficulty moving beyond brainstorming related concepts. Based on this, we suggest that these two methods for concept mapping can be best used for different assessment purposes and at different points in NOS instruction.

Clinical concept maps in nursing education: An effective way to link theory and practice.  

Science.gov (United States)

Historically, nursing care plans have been utilized in nursing education to identify actual and potential health problems. The rigid structure of these plans often makes it challenging for students to assimilate data to identify and understand the many diverse patient problems. To promote critical thinking, improve problem-solving skills and foster understanding of the interrelationships among patient's health concerns, second year baccalaureate students developed and implemented concept maps using the nursing process in the clinical setting. An overview of what concept maps are, how the concept maps were developed and utilized in the clinical setting, implications for clinical teaching and outcomes of the experience are highlighted.

Mapping of biomedical text to concepts of lexicons, terminologies, and ontologies.  

Science.gov (United States)

Concept mapping is a fundamental task in biomedical text mining in which textual mentions of concepts of interest are annotated with specific entries of lexicons, terminologies, ontologies, or databases representing these concepts. Though there has been a significant amount of research, there are still a limited number of practical, publicly available tools for concept mapping of biomedical text specified by the user as an independent task. In this chapter, several tools that can automatically map biomedical text to concepts from a wide range of terminological resources are presented, followed by those that can map to more restricted sets of these resources. This presentation is intended to serve as a guide to researchers without a background in biomedical concept mapping of text for the selection of an appropriate tool based on usability, scalability, configurability, balance between precision and recall, and the desired set of terminological resources with which to annotate the text. Only with effective automatic concept-mapping tools will systems be able to scalably analyze the biomedical literature and other large sets of documents as a fundamental part of more complex text-mining tasks such as information extraction and hypothesis evaluation and generation.

Worth 1,000 words: concept mapping for tenure and promotion.  

Science.gov (United States)

Organizing tenure/promotion dossiers can be a daunting task for junior faculty. As an adjunct to a strong program of scholarship, concept mapping can help as a concise and effective tool when applying for tenure and promotion. Concept mapping is explained here as a value-added, graphic method for junior faculty to use in presenting their scholarship accomplishments in the tenure and promotion dossier in a single overview beyond the written narrative. Further, skills in developing concept maps can be used as a mentoring technique, simultaneously helping faculty shape their scholarship as they progress toward tenure. The historically situated picture presented by a concept map is worth a thousand words. PMID:21078503

Nanoscale elastic modulus mapping revisited: The concept of effective mass  

Science.gov (United States)

We introduce the effective mass of the nanoindenter tip/sample assembly into the nanoscale dynamic modulus mapping technique that allows us to extract the correct storage modulus from the measured contact stiffness. We show that the developed approach successfully works for both stiff ceramics, such as fused quartz, and much compliant polymer materials, such as polycarbonate (PC) and poly(methyl methacrylate) (PMMA).

A comparison of inquiry-based teaching through concept maps and traditional teaching in biology  

Science.gov (United States)

The purpose of this study was to investigate affective outcomes and academic achievement for students enrolled in high school biology when instruction included concept-mapping. The research design was quasi-experimental and allowed for a comparison between an experimental group who constructed concept maps and a control group who received traditional biology instruction. The subjects were 140 ninth-grade students, distributed into six intact biology classes, three honors and three general biology classes. Chapter tests and a textbook generated 9-week comprehensive posttest were used to measure achievement. ANCOVA analysis on the comprehensive posttest indicated no significant overall effect of concept mapping on biology achievement across the whole quarter when controlling for the quarter pretest. Chi-square analyses were performed to measure students' attitude toward biology class and activities. The experimental group indicated higher than expected tendency to be positive about the instructional methods, however, the control group indicated fewer than expected positive responses. T-tests were conducted to determine the differences between the experimental and control groups on chapter tests with or without concept mapping. The group with concept mapping scored significantly better than those with traditional methods. Honors class comparisons indicated a significant difference between groups at presearch were provided related to the use of concept mapping.

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

Science.gov (United States)

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

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.

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.

An analysis, using concept mapping, of diabetic patients' knowledge, before and after patient education.  

Science.gov (United States)

This study was designed to assess whether concept maps used with diabetic patients could describe their cognitive structure, before and after having followed an educational programme. Ten diabetic patients, in Paris and Geneva, were interviewed and, during the interview, a concept map was drawn up by the researcher, using the patient's words. This was done on three different occasions: the first day of the educational programme (Pre-evaluation), the last day (Post 1) of a week of education, then 3 to 4 months after education (Post 2). Twenty-eight maps were analysed, using a grid that quantified and qualified the knowledge expressed (knowledge categories, concept links, exactitude) and the organization of that knowledge (hierarchization of concept, cross-links). The examples shown in the maps of the 10 patients gave an illustration of how knowledge was developed or maintained with education, and also showed some learning difficulties encountered by the patients, the changes or preservation of their beliefs and the patients' preoccupations. This study shows that concept maps can be a suitable technique to explore the type and organization of the patients' prior knowledge and to visualize what they have learned after an educational programme.

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

Energy Technology Data Exchange (ETDEWEB)

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.

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

Complexity Results and Approximation Strategies for MAP Explanations  

CERN Document Server

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

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.

Effects of concept map teaching on students' critical thinking and approach to learning and studying.  

Science.gov (United States)

The purpose of this study was to explore the effects of concept mapping in developing critical thinking ability and approach to learning and studying. A quasi-experimental study design with a purposive sample was drawn from a group of nursing students enrolled in a medical-surgical nursing course in central Taiwan. Students in the experimental group were taught to use concept mapping in their learning. Students in the control group were taught by means of traditional lectures. After the intervention, the experimental group had better overall critical thinking scores than did the control group, although the difference was not statistically significant. After controlling for the effects of age and the pretest score on critical thinking using analysis of covariance, the experimental group had significantly higher adjusted mean scores on inference and overall critical thinking compared with the control group. Concept mapping is an effective tool for improving students' ability to think critically. PMID:21524017

Concept mapping and the fundamental problem of moving between knowledge structures  

Directory of Open Access Journals (Sweden)

Full Text Available A concept map provides a ?snap shot? of a student?s understanding that is frozen in time by drawing it out on paper or on a computer screen. However, to represent the dynamic state of student learning, concept maps either need to emphasise dynamism (through the phrases that are chosen to act as links within the propositions that form the map, or need to be viewed as a single perspective on a more complex situation that can only be fully appreciated by considering movement between knowledge structures (e.g. through sequential mapping over time, or by indicating relationships between map structures that represent complementary learning contexts. The recognition of the importance of movement between knowledge structures needs careful management, whether teaching is conducted as a face-to-face activity or (increasingly as a digital/online activity. Existing models of e-learning development (such as the TPACK model can be modified to accommodate a multiple perspectives view. When the purpose of teaching is the promotion of students? ability to move between knowledge structures (rather than acquiring a single structure, the purpose of producing a concept map changes and becomes part of a wider dynamic process of learning, rather than providing a static record of what has already been learnt.

Student perceptions and use of an assessment rubric for a group concept map in physiology  

Science.gov (United States)

We previously reported how the opinions of second-year dentistry students and faculty members can be used to construct an assessment rubric to grade group-based concept maps in physiology (14). This article describes the second phase of this study of the subsequent year's cohort. A case study approach was used to investigate how groups of students used the criteria to complete their complex concept maps. Students' opinions about the assessment task and newly constructed rubric were sampled. Opinions across groups were correlated to academic achievements in the course. Two groups of four students volunteered to be videorecorded during a 4-h workshop, during which they completed their maps. The mapping task was not generally favored by students. However, those students who did favor the task achieved higher academic grades. Most students favored the newly constructed assessment rubric, commenting that it was easy to understand, fair, and appropriate, but reported that extra guidance from tutors and other resources were required. Coded videorecordings of the two observation groups revealed complex interactions around the three criteria of content, logic and understanding, and presentation. Two broad patterns of working were identified. One group distributed their efforts more evenly across the criteria, whereas the other group completed their maps by addressing the criteria in stages. These findings clearly indicate the academic challenges and social complexity in how students work in groups to complete complex concept maps in physiology.

Full Text Available This paper analyzes the use of collaborative concept maps in multimedia learning tasks. Specifically, the effect of a cognitive aid (providing students a list of main concepts to generate a concept map on the performance of collaborative concept mapping and on the level of collaboration in this task is discussed. The study was carried out with 57 university students, grouped into 19 triads, assigned to one of two conditions: with and without the support of a list of key concepts. It was found that the first condition promoted higher quality concept maps; however, the cognitive aid did not have significant effect on the levels of collaboration perceived by the team members. In the discussion and conclusions, the implications of these results for the design and implementation of collaborative interventions based on the use of technological tools and concept mapping are pointed out.

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.

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 mapping of diet and physical activity: uncovering local stakeholders perception in the Quebec City region.  

Science.gov (United States)

Overweight and obesity are major public health concerns that are neither evenly distributed among the population nor between regions. Many studies suggest that beyond individual characteristics, the place where one lives influences lifestyle choices that underpin overweight and obesity. We observed such a situation in the province of Quebec (Canada), and because data availability from surveys was limited to a local level, the observed overweight disparities between local communities could not be entirely explained. Aiming to uncover local factors not captured by national survey data sets and in order to aid local level intervention, we investigated how the overweight problem was perceived by stakeholders through a concept mapping methodology. Concept mapping is a mixed method that relies upon stakeholders' perception as well as statistical techniques to draw a synthesis of the problem in the form of a conceptual map. A total of 45 stakeholders working in four areas with contrasting overweight prevalence in the Quebec City region were involved in the process. The map enables a global understanding of stakeholders' perception. This perception is not necessarily in line with public health knowledge however. For example, key concepts on the map suggest that physical activity is perceived to be much more important than diet with regards to population overweight and that urban design elements seem to be of low concern. Concept mapping is an innovative tool for planning and evaluation and can help stakeholders to develop adapted interventions to promote healthy lifestyle. It also provides relevant information to enhance the comprehension of local health disparities with a geographical perspective where data availability is limited. PMID:21030123

Concept mapping One-Carbon Metabolism to model future ontologies for nutrient-gene-phenotype interactions.  

Science.gov (United States)

Advances in the development of bioinformatic tools continue to improve investigators' ability to interrogate, organize, and derive knowledge from large amounts of heterogeneous information. These tools often require advanced technical skills not possessed by life scientists. User-friendly, low-barrier-to-entry methods of visualizing nutrigenomics information are yet to be developed. We utilized concept mapping software from the Institute for Human and Machine Cognition to create a conceptual model of diet and health-related data that provides a foundation for future nutrigenomics ontologies describing published nutrient-gene/polymorphism-phenotype data. In this model, maps containing phenotype, nutrient, gene product, and genetic polymorphism interactions are visualized as triples of two concepts linked together by a linking phrase. These triples, or "knowledge propositions," contextualize aggregated data and information into easy-to-read knowledge maps. Maps of these triples enable visualization of genes spanning the One-Carbon Metabolism (OCM) pathway, their sequence variants, and multiple literature-mined associations including concepts relevant to nutrition, phenotypes, and health. The concept map development process documents the incongruity of information derived from pathway databases versus literature resources. This conceptual model highlights the importance of incorporating information about genes in upstream pathways that provide substrates, as well as downstream pathways that utilize products of the pathway under investigation, in this case OCM. Other genes and their polymorphisms, such as TCN2 and FUT2, although not directly involved in OCM, potentially alter OCM pathway functionality. These upstream gene products regulate substrates such as B12. Constellations of polymorphisms affecting the functionality of genes along OCM, together with substrate and cofactor availability, may impact resultant phenotypes. These conceptual maps provide a foundational framework for development of nutrient-gene/polymorphism-phenotype ontologies and systems visualization. PMID:25091042

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.

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.

Semantic Similarity Computation and Concept Mapping in Earth and Environmental Science  

Science.gov (United States)

Ontologies have been widely adopted and used by Earth and Environmental Science community to capture and represent knowledge in the domain. One of the major problem that prevent us to combine and reuse these ontologies to solve more interesting problems is semantic heterogeneity problem, for example, same vocabularies from different ontologies may refer to different concept; or different terms from different ontologies may have same meaning. In this proposed work, we will address the problem by (1) developing a semantic similarity computation model to compute similarity among the concepts in Earth and Environmental Science; (2) based on the computation model, we will implement concept mapping tool that creates alignment for concepts that are semantically the same; (3) we will demonstrate the effectiveness of the tool using GCMD and CLEAN vocabularies and other earth science related ontologies.

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

Science.gov (United States)

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

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.

Retrieval practice produces more learning than elaborative studying with concept mapping.  

Science.gov (United States)

Educators rely heavily on learning activities that encourage elaborative studying, whereas activities that require students to practice retrieving and reconstructing knowledge are used less frequently. Here, we show that practicing retrieval produces greater gains in meaningful learning than elaborative studying with concept mapping. The advantage of retrieval practice generalized across texts identical to those commonly found in science education. The advantage of retrieval practice was observed with test questions that assessed comprehension and required students to make inferences. The advantage of retrieval practice occurred even when the criterial test involved creating concept maps. Our findings support the theory that retrieval practice enhances learning by retrieval-specific mechanisms rather than by elaborative study processes. Retrieval practice is an effective tool to promote conceptual learning about science. PMID:21252317

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

Directory of Open Access Journals (Sweden)

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

Radiation treatment of brain tumors: Concepts and strategies  

International Nuclear Information System (INIS)

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

Effect of Concept Mapping on Approach to Learning Among Nursing Students  

Directory of Open Access Journals (Sweden)

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

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

Recent advances in parametric neuroreceptor mapping with dynamic PET: basic concepts and graphical analyses.  

Science.gov (United States)

Tracer kinetic modeling in dynamic positron emission tomography (PET) has been widely used to investigate the characteristic distribution patterns or dysfunctions of neuroreceptors in brain diseases. Its practical goal has progressed from regional data quantification to parametric mapping that produces images of kinetic-model parameters by fully exploiting the spatiotemporal information in dynamic PET data. Graphical analysis (GA) is a major parametric mapping technique that is independent on any compartmental model configuration, robust to noise, and computationally efficient. In this paper, we provide an overview of recent advances in the parametric mapping of neuroreceptor binding based on GA methods. The associated basic concepts in tracer kinetic modeling are presented, including commonly-used compartment models and major parameters of interest. Technical details of GA approaches for reversible and irreversible radioligands are described, considering both plasma input and reference tissue input models. Their statistical properties are discussed in view of parametric imaging. PMID:25260795

Teaching Plate Tectonic Concepts using GeoMapApp Learning Activities  

Science.gov (United States)

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

The use of concept maps during knowledge elicitation in ontology development processes – the nutrigenomics use case  

Directory of Open Access Journals (Sweden)

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

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.

Appropriate care for shelter-based abused women: concept mapping with Dutch clients and professionals.  

Science.gov (United States)

We conducted a concept mapping exercise to gain insight into the perspectives held by abused women and professionals with regard to appropriate care in Dutch women's shelters. Three brainstorming sessions generated 92 statements that were then rated by 56 clients and 51 professionals. A total of 11 clusters were identified. The three most important clusters were "help with finding a safe house if necessary," "safety and suitable care for the children," and "a personalized, respectful approach." The most important statement was "take women seriously and treat them with respect." The mapping exercise identified key practice-based elements of intervention that should better accommodate the needs of shelter-based abused women. We have used these elements in developing a new intervention for shelter-based abused women in the Netherlands. PMID:24686124

A Data Distribution Aware Task Scheduling Strategy for MapReduce System  

Science.gov (United States)

MapReduce is a parallel programming system to deal with massive data. It can automatically parallelize MapReduce jobs into multiple tasks, schedule to a cluster built by PCs. This paper describes a data distribution aware MapReduce task scheduling strategy. When worker nodes requests for tasks, it will compute and obtain nodes' priority according to the times for request, the number of tasks which can be executed locally and so on. Meanwhile, it can also calculate tasks' priority according to the numbers of copies executed by the task, latency time of tasks and so on. This strategy is based on node and task's scheduling priority, fully considers data distribution in the system and thus schedules Map tasks to nodes having data in high probability, to reduce network overhead and improve system efficiency.

Mapping vulnerability and conservation adaptation strategies under climate change  

Science.gov (United States)

Identification of spatial gradients in ecosystem vulnerability to global climate change and local stressors is an important step in the formulation and implementation of appropriate countermeasures. Here we build on recent work to map ecoregional exposure to future climate, using an envelope-based gauge of future climate stability--defined as a measure of how similar the future climate of a region will be to the present climate. We incorporate an assessment of each ecoregion's adaptive capacity, based on spatial analysis of its natural integrity--the proportion of intact natural vegetation--to present a measure of global ecosystem vulnerability. The relationship between intactness (adaptive capacity) and stability (exposure) varies widely across ecoregions, with some of the most vulnerable, according to this measure, located in southern and southeastern Asia, western and central Europe, eastern South America and southern Australia. To ensure the applicability of these findings to conservation, we provide a matrix that highlights the potential implications of this vulnerability assessment for adaptation planning and offers a spatially explicit management guide.

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

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

International Nuclear Information System (INIS)

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

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.

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

Science.gov (United States)

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

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.

Improved encoding strategy for CPMG-based Bloch-Siegert B(1)(+) mapping.  

Science.gov (United States)

Bloch-Siegert (BS) based B(1)(+) mapping methods use off-resonant pulses to encode quantitative B(1)(+) information into the signal phase. It was recently shown that the principle behind BS-based B(1)(+) mapping can be expanded from spin echo (BS-SE) and gradient-echo (BS-FLASH) based BS B(1)(+) mapping to methods such as Carr, Purcell, Meiboom, Gill (CPMG)-based turbo-spin echo (BS-CPMG-TSE) and multi-spin echo (BS-CPMG-MSE) imaging. If CPMG conditions are preserved, BS-CPMG-TSE allows fast acquisition of the B(1)(+) information and BS-CPMG-MSE enables simultaneous mapping of B(1)(+), M(0), and T(2). To date, however, two separate MRI experiments must be performed to enable the calculation of B(1)(+) maps. This study investigated a modified encoding strategy for CPMG BS-based methods to overcome this limitation. By applying a "bipolar" off-resonant BS pulse before the refocusing pulse train, the needed phase information was able to be encoded into different echo images of one echo train. Thus, this technique allowed simultaneous B(1)(+) and T(2) mapping in a single BS-CPMG-MSE experiment. To allow single-shot B(1)(+) mapping, this method was also applied to turbo-spin echo imaging. Furthermore, the presented modification intrinsically minimizes phase-based image artifacts in BS-CPMG-TSE experiments. PMID:22190144

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

Directory of Open Access Journals (Sweden)

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

Concept Maps for the Modelling of Controlled Flexibility in Software Processes  

Science.gov (United States)

Software processes and corresponding models are dynamic entities that are often changed and evolved by skillful knowledge workers such as the members of a software development team. Consequently, process flexibility has been identified as one of the most important features that should be supported by both Process Modelling Languages (PMLs) and software tools that manage the processes. However, in the everyday practice, most software team members do not want total flexibility. They rather prefer to have controlled flexibility, i.e., to learn and follow advices previously modelled by a process engineer on which and how they can change the elements that compose a software process. Since process models constitute a preferred vehicle for sharing and communicating knowledge on software processes, the process engineer needs a PML that can express this controlled flexibility, along with other process perspectives. To achieve this enhanced PML, we first need a sound core set of concepts and relationships that defines the knowledge domain associated with the modelling of controlled flexibility. In this paper we capture and represent this domain by using Concept Maps (Cmaps). These include diagrams and descriptions that elicit the relationships between the concepts involved. The proposed Cmaps can then be used as input to extend a PML with modelling constructs to express controlled flexibility within software processes. Process engineers can use these constructs to define, in a process model, advices on changes that can be made to the model itself or to related instances. Software team members can then consult this controlled flexibility information within the process models and perform changes accordingly.

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

DEFF Research Database (Denmark)

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

A Reactive Scheduling Strategy Applied On MapReduce OLAM Operators System  

Directory of Open Access Journals (Sweden)

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

Indigenous Education and Knowledge - a de-legitimised Concept in the Education for All Strategies  

DEFF Research Database (Denmark)

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

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)

Using conceptual matrices, knowledge maps, and scripted cooperation to improve personal management strategies.  

Science.gov (United States)

Research in the area of substance abuse suggests that ineffective personal management strategies appear to be a major factor in abuse behavior. In this study, fifty-seven students in an intermediate level psychology class were provided with three tools previously found to enhance academic learning strategies--knowledge maps, scripted peer cooperation, and conceptual matrices--as a means of understanding and improving personal management strategies. Student ratings of the value of these activities were significantly higher than an average or moderate response. Individual differences appear to be an important consideration in predicting participants' perceptions of the value of this approach. Those who felt they had control of whatever happens to them, and those who perceived problems as impactful and had strong desires to change recurring problem situations, had the most positive reactions to the types of activities used in this study.

2009 Melbourne metropolitan sewerage strategy: a portfolio of decentralised and on-site concept designs.  

Science.gov (United States)

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

Conflicting modes of reasoning in the Assisted Migration debate: a concept mapping analysis  

Science.gov (United States)

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

The expression of depression among Javanese patients with major depressive disorder: a concept mapping study.  

Science.gov (United States)

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

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

Science.gov (United States)

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

The Glacier and Land Ice Surface Topography Interferometer: An Airborne Proof-of-concept Mapping Sensor  

Science.gov (United States)

In May 2009 a new radar technique for mapping ice surface topography was demonstrated in a Greenland campaign as part of the NASA International Polar Year activities. This was achieved by integrating a Ka-band single-pass interferometric synthetic radar on the NASA Dryden Gulfstream III for a coordinated deployment. Although the technique of using radar interferometry for mapping terrain has been demonstrated before, this is the first such application at millimeter-wave frequencies. This proof-of-concept demonstration was motivated by the Glacier and Land Ice Surface Topography Interferometer (GLISTIN) Instrument Incubator Program and furthermore, highly leveraged existing ESTO hardware and software assets (the Unmanned Airborne Vehicle Synthetic Aperture Radar (UAVSAR) and processor and the PR2 (precipitation radar 2) RF assembly and power amplifier). Initial Ka-band test flights occurred in March and April of 2009 followed by the Greenland deployment. Instrument performance indicates swath widths over the ice between 5-7km, with height precisions ranging from 30cm-3m at a posting of 3m x 3m. However, for this application the electromagnetic wave will penetrate an unknown amount into the snow cover thus producing an effective bias that must be calibrated. This penetration will be characterized as part of this program and is expected to vary as a function of snow wetness and radar incidence angle. To evaluate this, we flew a coordinated collection with the NASA Wallops Airborne Topographic Mapper on a transect from Greenland’s Summit its West coast. This flight included two field calibration sites at Colorado Institute for Research in Environmental Science’s Swiss Camp and the National Science Foundation’s Summit station. Additional collections entailed flying a grid over Jakobshavn glacier which were repeated after 6 days to reveal surface dynamics. In this time frame we were able to observe horizontal motion of over 1km on the glacier. While developed for relevancy to ice surface mapping, the Ka-band interferometer was able to make targeted observations relevant for the Surface Water and Ocean Topography (SWOT) mission. Most notably, en route to Greenland via North Dakota, data was collected in the “SWOT-like” geometry by rolling the GIII toward nadir and collecting nadir data over surface water targets (Red and Missouri Rivers, Devils Lake, ND and the Big Bog, MN). Flying into Thule, SWOT data was also collected over sea ice. In summary, the campaign and demonstration was highly successful. Not only were we able to achieve the primary objective of validated data collections for ice-surface topography, but we also gathered unique observations that will be used by the SWOT mission. In the next year, the detailed processing, absolute calibration and intersensor comparisons will enable us ultimately to produce a high quality topographic map of Jakobshavn as an IPY reference for measuring future changes in ice elevation. Finally, our experiment has paved the way to make more topographic products available to glaciologists, either through dedicated airborne campaigns, or ultimately as a satellite mission.

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

Science.gov (United States)

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

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.

Energy Management Strategies based on efficiency map for Fuel Cell Hybrid Vehicles  

Energy Technology Data Exchange (ETDEWEB)

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

A Planetary Protection Strategy for the Mars Aerial Regional-Scale Environmental Survey (ARES) Mission Concept  

Science.gov (United States)

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

A two-dimensional mutate-and-map strategy for non-coding RNA structure  

Science.gov (United States)

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

The effectiveness of learning with concept mapping on the science problem-solving of sixth-grade children  

Science.gov (United States)

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

The use of concept mapping and vee heuristics in higher education to promote critical reflection and meaningful learning  

Directory of Open Access Journals (Sweden)

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

Integrating non-animal test information into an adaptive testing strategy - skin sensitization proof of concept case.  

Science.gov (United States)

There is an urgent need to develop data integration and testing strategy frameworks allowing interpretation of results from animal alternative test batteries. To this end, we developed a Bayesian Network Integrated Testing Strategy (BN ITS) with the goal to estimate skin sensitization hazard as a test case of previously developed concepts (Jaworska et al., 2010). The BN ITS combines in silico, in chemico, and in vitro data related to skin penetration, peptide reactivity, and dendritic cell activation, and guides testing strategy by Value of Information (VoI). The approach offers novel insights into testing strategies: there is no one best testing strategy, but the optimal sequence of tests depends on information at hand, and is chemical-specific. Thus, a single generic set of tests as a replacement strategy is unlikely to be most effective. BN ITS offers the possibility of evaluating the impact of generating additional data on the target information uncertainty reduction before testing is commenced. PMID:21993957

Directory of Open Access Journals (Sweden)

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

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.

Strategies for Reliable Exploitation of Evolutionary Concepts in High Throughput Biology  

Directory of Open Access Journals (Sweden)

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

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

Science.gov (United States)

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

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

Science.gov (United States)

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

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

Thinking Like a Scientist: Using Vee-Maps to Understand Process and Concepts in Science  

Science.gov (United States)

It is considered important for students to participate in scientific practices to develop a deeper understanding of scientific ideas. Supporting students, however, in knowing and understanding the natural world in connection with generating and evaluating scientific evidence and explanations is not easy. In addition, writing in science can help students to understand such connections as they communicate what they know and how they know it. Although tools such as vee-maps can scaffold students' efforts to design investigations, we know less about how these tools support students in connecting scientific ideas with the evidence they are generating, how these connections develop over time, or how writing can be used to encourage such connections. In this study, we explored students' developing ability to reason scientifically by examining the relationship between students' understanding of scientific phenomena and their understanding of how to generate and evaluate evidence for their ideas in writing. Three high school classes completed three investigations. One class used vee-mapping each time, one used vee-mapping once, and one did not use vee-mapping. Students' maps and written reports were rated for understanding of relevant science procedural and conceptual ideas. Comparisons between groups and over time indicate a positive relationship between improved procedural and conceptual understanding. Findings also indicate that improved procedural understanding preceded improved conceptual understanding, and thus, multiple experiences were needed for students to connect evidence and explanation for science phenomena.

Considerations on symbology, data requirements, and operational concept for integral NOTAM visualization on airport moving map displays  

Science.gov (United States)

Surface Movement is one of the most challenging phases of flight. To support the flight crew in this critical flight phase and to prevent serious incidents and accidents, of which Runway Incursions are the by far most safety-critical, the electronic airport moving map display has evolved as the key technology to increase the flight crew's situational awareness on the airport surface over the past decade. However, the airport moving map is limited to quasi-static airport information due to the envisaged 28 day update cycle of the underlying Aerodrome Mapping Database (AMDB), and thus does not include information on safety-relevant short-term and temporary changes such as runway closures or restrictions. Currently, these are conveyed on paper through the Pre-Flight Information Bulletin (PIB), a plain-language compilation of current Notices to Airmen (NOTAM) and other information of urgent character. In this context, the advent of airport moving map technology leads to a disparity in the conspicuousness of information, resulting in the danger that e.g. a runway that is not displayed as closed on the airport moving map might be perceived as open even if contrary NOTAM information exists on paper elsewhere in the cockpit. This calls for an integrated representation of PIB/NOTAM and airport moving map information. Piloted evaluations conducted by the Institute of Flight Systems and Automatic Control have already confirmed the high operational relevance of presenting runway closures on an airport moving map. Based on the results of these trials, this paper expands our previous work by addressing the various pre-requisites of an integral NOTAM visualization, ranging from the development of appropriate symbology to an operational concept enabling the transition from conventional to electronic, machine-readable NOTAM information without shifting responsibility and workload from the dispatcher to the flight deck. Employing Synthetic Vision techniques, a complete symbology set for various cases of runway closures and other applicable runway and airport restrictions is derived, and the requirements on the underlying machine-readable NOTAM data are discussed. Finally, the concept of an electronic Pre-Flight Information Bulletin (ePIB) is used to facilitate the gradual integration of this technology in an airline operational workflow.

An investigation into high-achiever and low-achiever knowledge organisation and knowledge processing in concept mapping: A case study  

Science.gov (United States)

This study used concept map content analysis and interviews to gain insights into the knowledge organisation and knowledge processing of pre-service teachers. Forty-eight preservice teachers of elementary science from a teachers’ training college in Sarawak, Malaysia, participated in this study. Correlations between achievement and five concept map characteristics showed that there were significant positive correlations ( pscore of subjects’ concept maps, and significant negative correlations ( p<.01) between achievement and: the number of inappropriate links; and, the average number of inappropriate concepts per cluster. Interviews with high-achievers and lowachievers revealed that there were differences in the way they processed knowledge during concept mapping. The high-achievers were more thorough than were the low-achievers in cognitive processing of knowledge, taking time to make sense of concepts, sort and group concepts, form relevant links between concepts, and organise concepts hierarchically. Active cognitive processing of knowledge seems to be related to more complex, well-integrated cognitive structures for the material learned.

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.

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.

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.

Mapping the Moho with seismic surface waves: Sensitivity, resolution, and recommended inversion strategies  

Science.gov (United States)

Seismic surface waves have been used to study the Earth's crust since the early days of modern seismology. In the last decade, surface-wave crustal imaging has been rejuvenated by the emergence of new, array techniques (ambient-noise and teleseismic interferometry). The strong sensitivity of both Rayleigh and Love waves to the Moho is evident from a mere visual inspection of their dispersion curves or waveforms. Yet, strong trade-offs between the Moho depth and crustal and mantle structure in surface-wave inversions have prompted doubts regarding their capacity to resolve the Moho. Although the Moho depth has been an inversion parameter in numerous surface-wave studies, the resolution of Moho properties yielded by a surface-wave inversion is still somewhat uncertain and controversial. We use model-space mapping in order to elucidate surface waves' sensitivity to the Moho depth and the resolution of their inversion for it. If seismic wavespeeds within the crust and upper mantle are known, then Moho-depth variations of a few kilometres produce large (over 1 per cent) perturbations in phase velocities. However, in inversions of surface-wave data with no a priori information (wavespeeds not known), strong Moho-depth/shear-speed trade-offs will mask about 90 per cent of the Moho-depth signal, with remaining phase-velocity perturbations 0.1-0.2 per cent only. In order to resolve the Moho with surface waves alone, errors in the data must thus be small (up to 0.2 per cent for resolving continental Moho). If the errors are larger, Moho-depth resolution is not warranted and depends on error distribution with period, with errors that persist over broad period ranges particularly damaging. An effective strategy for the inversion of surface-wave data alone for the Moho depth is to, first, constrain the crustal and upper-mantle structure by inversion in a broad period range and then determine the Moho depth in inversion in a narrow period range most sensitive to it, with the first-step results used as reference. We illustrate this strategy with an application to data from the Kaapvaal Craton. Prior information on crustal and mantle structure reduces the trade-offs and thus enables resolving the Moho depth with noisier data; such information should be sought and used whenever available (as has been done, explicitly or implicitly, in many previous studies). Joint analysis or inversion of surface-wave and other data (receiver functions, topography, gravity) can reduce uncertainties further and facilitate Moho mapping. Alone or as a part of multi-disciplinary datasets, surface-wave data offer unique sensitivity to the crustal and upper-mantle structure and are becoming increasingly important in the seismic imaging of the crust and the Moho.

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.

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.

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.

An explanatory model of academic achievement based on aptitudes, goal orientations, self-concept and learning strategies.  

Science.gov (United States)

As a result of studies examining factors involved in the learning process, various structural models have been developed to explain the direct and indirect effects that occur between the variables in these models. The objective was to evaluate a structural model of cognitive and motivational variables predicting academic achievement, including general intelligence, academic self-concept, goal orientations, effort and learning strategies. The sample comprised of 341 Spanish students in the first year of compulsory secondary education. Different tests and questionnaires were used to evaluate each variable, and Structural Equation Modelling (SEM) was applied to contrast the relationships of the initial model. The model proposed had a satisfactory fit, and all the hypothesised relationships were significant. General intelligence was the variable most able to explain academic achievement. Also important was the direct influence of academic self-concept on achievement, goal orientations and effort, as well as the mediating ability of effort and learning strategies between academic goals and final achievement.

A strategy to rotate the Mars Observer orbit node line to advance the mapping schedule  

Science.gov (United States)

The Mars Observer (MO) spacecraft was successfully launched on September 25, 1992 and will arrive at Mars on August 24, 1993. At Mars, the spacecraft will study the planet's surface, atmosphere, and gravitational and magnetic fields. In order to achieve these scientific objectives, MO will be placed in a 2 PM (descending node) sun-synchronous orbit. Upon arrival at Mars, however, the longitude of the descending node will be approximately 15 deg greater than the desired value. The baseline plan requires a 59 day `waiting' period for the correct solar orientation to occur. During this period, 28 days are required for scientific experimentation but the remaining 30.6 days potentially could be eliminated. The strategy developed in this study examined the possibility of using any `excess' Delta-V available at Mars arrival to rotate the node line to the desired value and thus allow mapping to begin earlier. A preliminary analysis completed prior to launch is described that examined the entire launch period including the required Delta-V to perform the needed nodal rotation. A more detailed study performed after launch is also summarized.

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.

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

International Nuclear Information System (INIS)

A Dual Functional Lithium Lead (DFLL) TBM (Test Blanket Module) concept for testing in ITER has been proposed by Chinese Party to demonstrate the technologies of the liquid lithium lead (LiPb) breeder blankets, including Quasi-Static Lithium Lead (SLL) breeder blanket and the Dual-cooled Lithium Lead (DLL) breeder blanket, which emphasizes the balance and the consistence between the risk and the attractiveness of blanket technology development. Considering the confliction between the limited ITER resources for TBM testing and the requirement of various blanket concepts proposed by Parties, an effective testing strategy has been proposed to achieve the target of testing both SLL and DLL blanket concepts, technologies, and design tools. It covers three phases: materials R and D and small-scale out-of-pile mockup testing in loops, middle-scale TBMs pre-testing in EAST (the superconducting tokamak in China), and full-scale consecutive TBMs corresponding to different operation phases of ITER during the first 10 years. Description of TBM system concept and the testing strategy combining TBMs testing, in sequence and in parallel, in EAST and ITER, are presented in this contribution. (author)

Mapping the Moho with seismic surface waves: A review, resolution analysis, and recommended inversion strategies  

Science.gov (United States)

The strong sensitivity of seismic surface waves to the Moho is evident from a mere visual inspection of their dispersion curves or waveforms. Rayleigh and Love waves have been used to study the Earth's crust since the early days of modern seismology. Yet, strong trade-offs between the Moho depth and crustal and mantle structure in surface-wave inversions prompted doubts regarding their capacity to resolve the Moho. Here, we review surface-wave studies of the Moho, with a focus on early work, and then use model-space mapping to establish the waves' sensitivity to the Moho depth and the resolution of their inversion for it. If seismic wavespeeds within the crust and upper mantle are known, then Moho-depth variations of a few kilometres produce large (> 1%) perturbations in phase velocities. However, in inversions of surface-wave data with no a priori information (wavespeeds not known), strong Moho-depth/shear-speed trade-offs will mask ~ 90% of the Moho-depth signal, with remaining phase-velocity perturbations ~ 0.1% only. In order to resolve the Moho with surface waves alone, errors in the data must thus be small (up to ~ 0.2% for resolving continental Moho). With larger errors, Moho-depth resolution is not warranted and depends on error distribution with period. An effective strategy for the inversion of surface-wave data alone for the Moho depth is to, first, constrain the crustal and upper-mantle structure by inversion in a broad period range and then determine the Moho depth in inversion in a narrow period range most sensitive to it, with the first-step results used as reference. Prior information on crustal and mantle structure reduces the trade-offs and thus enables resolving the Moho depth with noisier data; such information should be used whenever available. Joint analysis or inversion of surface-wave and other data (receiver functions, topography, gravity) can reduce uncertainties further and facilitate Moho mapping.

Topographic map formation by maximizing unconditional entropy: a plausible strategy for "online" unsupervised competitive learning and nonparametric density estimation.  

Science.gov (United States)

An unsupervised competitive learning rule, called the vectorial boundary adaptation rule (VBAR), is introduced for topographic map formation. Since VBAR is aimed at producing an equiprobable quantization of the input space, it yields a nonparametric model of the input probability density function. Furthermore, since equiprobable quantization is equivalent to unconditional entropy maximization, we argue that this is a plausible strategy for maximizing mutual information (Shannon information rate) in the case of "online" learning. We use mutual information as a tool for comparing the performance of our rule with Kohonen's self-organizing (feature) map algorithm. PMID:18263523

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

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

Science.gov (United States)

Magellan, a NASA mission to Venus in the early 1990's, mapped nearly the entire surface of Venus with an S-band (12 cm) synthetic aperture radar and microwave radiometer and made radar altimeter measurements of the topography. These measurements revolutionized our understanding of the geomorphology, geology and geophysical processes that have shaped the evolution of the surface of Venus. The Magellan spacecraft had an elliptical orbit with an apoapsis of approximately 8000 km and a periapsis of 257 km and an orbital inclination of 86°. In this way the radar was able to collect long strips of data approximately 10000 km in length running north to south with altitudes varying from 3000 km to 257 km. During the remainder of the orbit the collected data was down linked to earth. The SAR mode operated in burst mode fashion whereby it transmitted a small string of pulses up to a couple of hundred pulses in length followed by a quiescent period when the radar ceased transmission and allowed interleaved operation of the altimeter and radiometer modes. This mode of operation allowed for a significant reduction in downlinked SAR imaging data at the expense of azimuth (i.e. along-track) resolution. However, the lack of finer resolution imagery and topography of the surface than that obtained by the Magellan mission has hampered the definitive answer to key questions concerning the processes and evolution of the surface of Venus. The Venus Emissivity, Radio Science, InSAR Topography And Spectroscopy (VERITAS) Mission is a proposed mission to Venus designed to obtain high resolution imagery and topography of the surface using an X-band radar configured as a single pass radar interferometer coupled with a multispectral NIR emissivity mapping capability. VERITAS would map surface topography with a spatial resolution of 250 m and 5 m vertical accuracy and generate radar imagery with 30 m spatial resolution. These capabilities represent an order of magnitude or better improvement of the Magellan system and are expected to reveal definitive information on processes not possible with the Magellan data. The combination of surface topography and image data provide unprecedented knowledge of Venus' tectonic and impact history, the timing and mechanisms of volcanic resurfacing, and the mantle processes responsible for them. The combination of instruments on VERITAS, and in particular the InSAR instrument, is designed to address a series of focused hypothesis driven questions left unresolved by the Magellan mission for example: 1) Is there evidence for a past tectonic or cratered surface beneath the plains? and 2) How and when did Venus resurface? This talk will present an overview of the proposed VERITAS mission, the radar instrument design and trade options and the projected performance as well as a brief overview of some of the major science objectives. This research was conducted at the Jet Propulsion Laboratory, California Institute of Technology, under contract with the National Aeronautics and Space Administration.

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.

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

Science.gov (United States)

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

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.

Surfactant replacement and open lung concept – Comparison of two treatment strategies in an experimental model of neonatal ARDS  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Several concepts of treatment in neonatal ARDS have been proposed in the last years. The present study compared the effects of open lung concept positive pressure ventilation (PPVOLC with a conventional ventilation strategy combined with administration of two different surfactant preparations on lung function and surfactant homoeostasis. Methods After repeated whole-lung saline lavage, 16 newborn piglets were assigned to either PPVOLC (n = 5 or surfactant treatment under conventional PPV using a natural bovine (n = 5 or a monomeric protein B based surfactant (n = 6. Results Comprehensive monitoring showed each treatment strategy to improve gas exchange and lung function, although the effect on PaO2 and pulmonary compliance declined over the study period in the surfactant groups. The overall improvement of the ventilation efficiency index (VEI was significantly greater in the PPVOLC group. Phospholipid and protein analyses of the bronchoalveolar lavage fluid showed significant alterations to surfactant homoeostasis in the PPVOLC group, whereas IL-10 and SP-C mRNA expression was tendentially increased in the surfactant groups. Conclusion The different treatment strategies applied could be shown to improve gas exchange and lung function in neonatal ARDS. To which extent differences in maintenance of lung function and surfactant homeostasis may lead to long-term consequences needs to be studied further.

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’.

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

International Nuclear Information System (INIS)

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

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.

Testing the Effects of Educational Strategies on Comprehension of a Genomic Concept Using Virtual Reality Technology  

Science.gov (United States)

Objective Applying genetic susceptibility information to improve health will likely require educating patients about abstract concepts, for which there is little existing research. This experimental study examined the effect of learning mode on comprehension of a genomic concept. Methods 156 individuals aged 18–40 without specialized knowledge were randomly assigned to either a virtual reality active learning or didactic learning condition. The outcome was comprehension (recall, transfer, mental models). Results Change in recall was greater for didactic learning than active learning (p<0.001). Mean transfer and change in mental models were also higher for didactic learning (p<0.0001 and p<0.05, respectively). Believability was higher for didactic learning (p<0.05), while ratings for motivation (p<0.05), interest (p<0.0001), and enjoyment (p<0.0001) were higher for active learning, but these variables did not mediate the association between learning mode and comprehension. Conclusion These results show that learning mode affects comprehension, but additional research is needed regarding how and in what contexts different approaches are best for educating patients about abstract concepts. Practice implications Didactic, interpersonal health education approaches may be more effective than interactive games in educating patients about abstract, unfamiliar concepts. These findings indicate the importance of traditional health education approaches in emerging areas like genomics. PMID:19409749

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

International Nuclear Information System (INIS)

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

The two-phase battery concept: a new strategy for high performance lithium polymer batteries  

Science.gov (United States)

A new concept is proposed to realize high performance lithium polymer batteries. The two-phase battery concept is based on the use of two polyethers of different molecular weight. A low molecular weight polyether is used in the composite cathode to assure high ionic conductivity while a high molecular weight polyether is used in the electrolyte formulation. In this work, a composite cathode based on a solid, low molecular weight poly(ethylenglycol) dimethyl ether (PEG-DME, M.W. 2000), was coupled with a solid polymer electrolyte (SPE) based on poly(ethylenoxide) (PEO, M.W. 4×10 6). The electrochemical stability window, evaluated by a slow sweep voltammetry, showed that the system has an anodic breakdown voltage higher than 4.0 V versus Li. The feasibility of two-phase batteries was evaluated by cycling tests. The results indicate that two-phase batteries have enhanced performance with respect to PEO based batteries.

Testing Communication Strategies to Convey Genomic Concepts Using Virtual Reality Technology  

Science.gov (United States)

Health professionals need to be able to communicate information about genomic susceptibility in understandable and usable ways, but substantial challenges are involved. We developed four learning modules that varied along two factors: (1) learning mode (active learning vs. didactic learning) and (2) metaphor (risk elevator vs. bridge) and tested them using a 2×2 between-subjects, repeated measures design. The study used an innovative virtual reality technology experimental platform; four virtual worlds were designed to convey the concept that genetic and behavioral factors interact to affect common disease risk. The primary outcome was comprehension (recall, transfer). Study participants were 42 undergraduates aged 19–23. The results indicated that the elevator metaphor better supported learning of the concept than the bridge metaphor. Mean transfer score was significantly higher for the elevator metaphor (p<0.05). Mean change in recall was significantly higher for didactic learning than active learning (p<0.05). However, mean ratings for variables posited to be associated with better learning (e.g., motivation) were generally higher for the active learning worlds. The results suggested that active learning might not always be more effective than didactic learning in increasing comprehension of health information. The findings also indicated that less complex metaphors might convey abstract concepts more effectively. PMID:19466649

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

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

Science.gov (United States)

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

Ukraine's uranium facilities are located in the central part of the country, in urbanized districts with a high population density and intensively developed industry and agriculture. Nearly 50 years of uranium mining and milling at these facilities have caused radioactive contamination of the environment. This paper is devoted to identification of the main sources of actual and potential releases of radioactive materials to the environment, assessment of the radiological and environment risk as a basis for remedial measures. Choice of the best strategy for site restoration are described in this paper. (author)

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)

Use of a group concept mapping approach to define learning outcomes for an interdisciplinary module in medicine.  

Science.gov (United States)

Learning outcomes are typically developed using standard group-based consensus methods. Two main constraints with standard techniques such as the Delphi method or expert working group processes are: (1) the ability to generate a comprehensive set of outcomes and (2) the capacity to reach agreement on them. We describe the first application of Group Concept Mapping (GCM) to the development of learning outcomes for an interdisciplinary module in medicine and engineering. The biomedical design module facilitates undergraduate participation in clinician-mentored team-based projects that prepare students for a multidisciplinary work environ
