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.

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

Science.gov (United States)

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

The Effect of Learner Constructed, Fill in the Map Concept Map Technique, and Summarizing Strategy on Iranian Pre-university Students’ Reading Comprehension  

Directory of Open Access Journals (Sweden)

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

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

Science.gov (United States)

The concept mapping technique has been proposed as a method for examining the evolving nature of students' conceptualizations of scientific concepts, and promises insight into a dimension of learning different from the one accessible through more conventional classroom testing techniques. The theory behind concept mapping is based on an assumption that knowledge acquisition is accomplished through "linking" of new information to an existing knowledge framework, and that meaningful (as opposed to arbitrary or verbatim) links allow for deeper understanding and conceptual change. Reflecting this theory, concept maps are constructed as a network of related concepts connected by labeled links that illustrate the relationship between the concepts. Two concepts connected by one such link make up a "proposition", the basic element of the concept map structure. In this paper, we examine the results of a pre- and post-test assessment program for an upper-division undergraduate geography course entitled "Mock Environmental Summit," which was part of a research project on assessment. Concept mapping was identified as a potentially powerful assessment tool for this course, as more conventional tools such as multiple-choice tests did not seem to provide a reliable indication of the learning students were experiencing as a result of the student-directed research, presentations, and discussions that make up a substantial portion of the course. The assessment program began at the beginning of the course with a one-hour training session during which students were introduced to the theory behind concept mapping, provided with instructions and guidance for constructing a concept map using the CMap software developed and maintained by the Institute for Human and Machine Cognition at the University of West Florida, and asked to collaboratively construct a concept map on a topic not related to the one to be assessed. This training session was followed by a 45-minute "pre-test" on the topic of global climate change, for which students were provided with a list of questions to guide their thoughts during the concept map construction. Following the pre-test, students were not exposed to further concept mapping until the end of the course, when they were asked to complete a "post-test" consisting of exactly the same task. In addition to a summary of our results, this paper presents an overview of available digital concept-mapping tools, proposed scoring techniques, and design principles to keep in mind when designing a concept-mapping assessment program. We also discuss our experience with concept map assessment, the insights it provided into the evolution in student understanding of global climate change that resulted from the course, and our ideas about the potential role of concept mapping in an overall assessment program for interdisciplinary and/or student-directed curricula.

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.

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

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

Science.gov (United States)

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

Attributed concept maps: fuzzy integration and fuzzy matching.  

Science.gov (United States)

A concept map, typically depicted as a connected graph, is composed of a collection of propositions. Each proposition forming a semantic unit consists of a small set of concept nodes interconnected to one another with relation links. Concept maps possess a number of appealing features which make them a promising tool for teaching, learning, evaluation, and curriculum planning. We extend concept maps by associating their concept nodes and relation links with attribute values which indicate the relative significance of concepts and relationships in knowledge representation. The resulting maps are called attributed concept maps (ACM). Assessing students will be conducted by matching their ACMs with those prebuilt by experts. The associated techniques are referred to as map matching techniques. The building of an expert ACM has in the past been done by only one specialist. We integrate a number of maps developed by separate experts into a single map, called the master map (MM), which will serve as a prototypical map in map matching. Both map integration and map matching are conceptualized in terms of fuzzy set discipline. Experimental results have shown that the proposed ideas of ACM, MM, fuzzy map integration, and fuzzy map matching are well suited for students with high performances and difficult subject materials.

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

Concept mapping and pupils’ learning in primary science in Singapore  

Directory of Open Access Journals (Sweden)

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

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.

Using Concept Maps to Plan an Introductory Structural Geology Course  

Science.gov (United States)

This report presents the results of incorporating constructivist methods, including concept maps, into an undergraduate structural geology curriculum. A concept map is a visual representation of concepts and their relationship to each other in a body of knowledge. They show the hierarchy of these concepts and emphasize the links between them. The overall goal of this project was to encourage students to adopt a deep/holistic approach to learning in order to better understand the concepts of structural geology. The authors sought to determine whether teaching methods became more overtly constructivist, whether there was a change in the order of presentation of topics, and whether the order of presentation normally followed by textbooks was the same as the order determined using concept maps.

Concept maps as network data: analysis of a concept map using the methods of social network analysis.  

Science.gov (United States)

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

Concept mapping and science achievement of middle-grade students  

Science.gov (United States)

This study was designed to examine the effects of concept mapping on science achievement of middle grade science students. Concept mapping is a graphic display of concepts and the relationships or links among them. A concept map represents the students' understanding of a body of knowledge. The subjects were one hundred eighty-two eighth grade students, distributed into eight intact earth science classes at Bowling Green Junior High School. Students were homogeneously grouped by above average and average ability levels. Therefore, the ability level variable was examined as a possible effect. Students were divided into four treatment groups (two per ability level) and four control groups (two per ability level). Two teachers were involved in teaching a unit on weather for nine weeks. The treatment groups constructed concept maps, while the control groups did not. Two testing instruments (a conventional weather test and six performance assessment items) were used to measure achievement. For this sample of students, analyses of covariance indicated no significant overall effects of treatment on science achievement. A weak but statistically students measured by combined performance assessment items. Similar to the literature reviewed, the results of this research are somewhat mixed. The results suggest that the effect of concept mapping on science achievement is not clear and science educators should be cautious as to its practical use in the classroom. Furthermore, the results suggest that researchers should continue to seek more data to either support or reject the effectiveness of concept mapping.

Conception and realization of a living map  

Science.gov (United States)

Our objective is to obtain a 'living map' in which the traditional elements of a map are not static but can evolve in real time and interact. We therefore developed a system with a graphic interface allowing simulations to be constructed and both natural and man-induced phenomena to be monitored in real time. For this system, we coupled an expert system and an image processing system specialized in Remote Sensing. These two components accept many kind of data (aerial photographs, satellite pictures, maps, digital elevation models, . . .) and interact in real time. The system is built with four levels and uses an object methodology. It works according to the semantic wealth of the handled objects. The hierarchy of handled graphic objects essentially includes the geo- referenced objects and the 'maps' objects. Our prototype uses the object-oriented expert system of Gensym 'G2' and the graphic visualization system developed by Latical, 'Visiter.' An example will be presented.

Business Negotiation Strategies: the Concept, Definitions and Process  

Directory of Open Access Journals (Sweden)

Full Text Available The modern business is developing in the context of rapid social and political changes, which contributes to the changes in economic and cultural priorities as well as mindset and behaviour of people. This puts new requirements on development and implementation of business negotiation strategies, aiming to ensure that during bargaining, everything is done to understand the other party and related contexts, to achieve mutual understanding, to reach common agreement and eventually find the optimal negotiating decision. The author of this article researched and analysed negotiation process concepts in the global scientific literature and practice. The article examines negotiation and bargaining concepts. Also, the global analysis of the scientific literature revealed that there is no single negotiation planning concept. The author defines the basic conceptual negotiation planning concepts. The paper deals with negotiation strategy conceptions used by scientists around the world. Conclusions present the proposals for further business negotiation research.Article in Lithuanian

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)

Abstract 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

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.

Scanning and Mapping Strategies for CMB Experiments  

CERN Document Server

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

The Spanish indoor radon mapping strategy.  

Science.gov (United States)

Indoor radon mapping still represents a valuable tool for drawing the picture of the exposure of general public due to radon and radon progeny inhalation in a residential context. The information provided by means of a map is useful not only as awareness and strategic element for authorities and policy-makers, but also as a scientific start-up point in the design of epidemiological and other specific studies on exposure to natural radiation. The requirements for a good mapping are related to harmonisation criteria coming from European recommendations, as well as to national/local characteristics and necessities. Around 12,000 indoor radon measurements have been made since the Spanish national radon programme began at the end of the 1980s. A significant proportion of them resulted from the last campaign performed from 2009 to 12. This campaign completed the first version of a map based on a grid 10 × 10 km(2). In this paper, the authors present the main results of a new map together with the criteria adopted to improve the number of measurements and the statistical significance of them. PMID:25013034

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

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.

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.

Vaccine strategies against schistosomiasis: from concepts to clinical trials.  

Science.gov (United States)

Schistosomiasis, the second major parasitic disease in the world after malaria, affects 200 million people. Vaccine strategies represent an essential component of the control of this chronic debilitating disease where the deposition of millions of eggs in the tissues is the main cause of pathology. Research developed in our laboratory over the last 20 years has led to the identification of novel effector mechanisms, pointing for the first time to the protective role of Th2 responses and of IgE antibodies now supported by seven studies in human populations. The identification and molecular cloning of a target antigen, a glutathione S-transferase (GST), has made it possible to demonstrate its vaccine potential in several animal species (rodents, cattle, primates) and to establish consistently the capacity of vaccination to reduce female worm fecundity and egg viability through the production of neutralizing antibodies (IgA and IgG). Following promising preclinical studies, clinical trials (phase I and II) have been undertaken using Schistosoma haematobium GST, Sh28GST. High titers of neutralizing antibodies were produced (IgG3 and IgA) together with Th2 cytokines, consistently with the concepts developed from experimental models. With these results we are on the way towards a feasible approach of vaccine development against a major human parasitic disease. PMID:11306914

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.

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.

Discrimination of mixed quantum states. Reversible maps and unambiguous strategies  

Energy Technology Data Exchange (ETDEWEB)

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.

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.

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

Directory of Open Access Journals (Sweden)

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

Adaptive fractionation therapy: I. Basic concept and strategy  

International Nuclear Information System (INIS)

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

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 plevel on the chapter pretest. There was also a significant difference on the chapter test after intervention, but this time at plevel. Although the general class comparisons indicated no significant difference on the chapter pretest, the experimental group scored significantly better than the control group on the chapter test following intervention. This suggests that average ability students benefit from concept mapping more than traditional instruction. In narrative self-evaluations, only a small percentage of participants overall listed concept mapping as the review activity that helped them learn most. Recommendations for practitioners and future research were provided related to the use of concept mapping.

A theoretical framework for the concept of 'Internet strategy'  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Organisations know that the Internet could or should play an important role in goal achievement, but are uncertain about its strategic application. It can therefore be said that the Internet remains largely 'a technology in search of a strategy'. This article explores 'Internet strategy' from the perspective of the corporate communication domain, specifically within the framework of two meta-theoretical approaches: the Excellence approach and the two-way symmetrical approach to public rel...

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

Directory of Open Access Journals (Sweden)

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

Discovering Concept Mappings by Similarity Propagation among Substructures  

Science.gov (United States)

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

ADDRESSING WATER FOOTPRINT CONCEPT: A DEMONSTRABLE STRATEGY FOR PAPERMAKING INDUSTRY  

Directory of Open Access Journals (Sweden)

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

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.

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

International Nuclear Information System (INIS)

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

Survey and comparison of nuclear power strategy and concepts worldwide  

International Nuclear Information System (INIS)

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

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.

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

Science.gov (United States)

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

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.

Peptide/protein-polymer conjugates: synthetic strategies and design concepts.  

Science.gov (United States)

This feature article provides a compilation of tools available for preparing well-defined peptide/protein-polymer conjugates, which are defined as hybrid constructs combining (i) a defined number of peptide/protein segments with uniform chain lengths and defined monomer sequences (primary structure) with (ii) a defined number of synthetic polymer chains. The first section describes methods for post-translational, or direct, introduction of chemoselective handles onto natural or synthetic peptides/proteins. Addressed topics include the residue- and/or site-specific modification of peptides/proteins at Arg, Asp, Cys, Gln, Glu, Gly, His, Lys, Met, Phe, Ser, Thr, Trp, Tyr and Val residues and methods for producing peptides/proteins containing non-canonical amino acids by peptide synthesis and protein engineering. In the second section, methods for introducing chemoselective groups onto the side-chain or chain-end of synthetic polymers produced by radical, anionic, cationic, metathesis and ring-opening polymerization are described. The final section discusses convergent and divergent strategies for covalently assembling polymers and peptides/proteins. An overview of the use of chemoselective reactions such as Heck, Sonogashira and Suzuki coupling, Diels-Alder cycloaddition, Click chemistry, Staudinger ligation, Michael's addition, reductive alkylation and oxime/hydrazone chemistry for the convergent synthesis of peptide/protein-polymer conjugates is given. Divergent approaches for preparing peptide/protein-polymer conjugates which are discussed include peptide synthesis from synthetic polymer supports, polymerization from peptide/protein macroinitiators or chain transfer agents and the polymerization of peptide side-chain monomers.

The concept of alternative strategies and its relevance to psychiatry and clinical psychology.  

Science.gov (United States)

The intent of this article is to introduce the evolutionary concept of alternative strategies into the fields of psychiatry and clinical psychology. In behavioral ecology, the term alternative strategies refers to the presence of two or more discrete behavioral variants among adults of one sex and one population when those variants serve the same functional end. Often discrete behavioral variants are associated with specific morphological, physiological, and life-history characters. The concept of alternative strategies has been applied to human behavior to explain the origin of some behavioral syndromes that are currently classified as mental disorders or emotional dysfunctions. Antisocial personality could represent a high-risk strategy of social defection associated with resource acquisition and reproduction. Insecure attachment could represent an evolved psychological mechanism that used the quality of parental care received during childhood as a cue for optimizing adult reproductive strategies. Since a major contribution of evolutionary theory is the insight that individual differences are core biological features of any animal species, including Homo sapiens, the application of the concept of alternative strategies to psychiatry and clinical psychology can be a powerful antidote to the growing tendency to medicalize human diversity.

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

Science.gov (United States)

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

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

Directory of Open Access Journals (Sweden)

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

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.

An Integrated in Silico Gene Mapping Strategy in Inbred Mice  

Digital Repository Infrastructure Vision for European Research (DRIVER)

In recent years in silico analysis of common laboratory mice has been introduced and subsequently applied, in slightly different ways, as a methodology for gene mapping. Previously we have demonstrated some limitation of the methodology due to sporadic genetic correlations across the genome. Here, we revisit the three main aspects that affect in silico analysis. First, we report on the use of marker maps: we compared our existing 20,000 SNP map to the newly released 140,000 SNP map. Second, w...

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.

The managers of building perceptions about the concept of organizational strategy: An exploratory study  

Directory of Open Access Journals (Sweden)

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.

The concept map as a tool for the collaborative construction of knowledge: A microanalysis of high school physics students  

Science.gov (United States)

Although concept mapping has been shown to help students in meaningful learning, particularly when done as a collaborative activity, little has been done to understand the microprocesses during the activity itself. However, in order to be able to improve the activity as a teaching and learning heuristic, we have to know more about the microprocesses that constitute concept mapping as process and as product. This study was designed to investigate concept mapping as a means of assessing the quality of student understanding from two perspectives: the analysis of the process of constructing meaning and the analysis of the products of this cognitive activity. An interpretive research methodology was adopted for the construction of meaning from the data. Twenty-nine students from two sections of a senior level high school physics course participated in the study. The data sources included videotapes, their transcripts, and all concept maps produced. Students worked in collaborative groups during all of the concept mapping sessions. Individual concept mapping was assessed twice, once delayed by a week, another time delayed by 6 weeks. To assess what happened to the cognitive achievement as the context of concept mapping changed from collaborative to individual activity, we used a tracer. A tracer is some bit of knowledge, procedure, or action that allows the researcher to follow a task through various settings. The concept maps as products differed in their hierarchical organization, the number of links, and the benefit to the individual students. Three major processes emerged, which students used to arrive at suitable propositions. Students mediated propositions verbally and nonverbally, they took adversarial positions and appealed to authority, and they formed temporary alliances based on presumed expertise. Both product and process hold promise but also show some limitations. On the positive side, concept mapping led to sustained discourse on the topic and improved the declarative knowledge of several students both in terms of the hierarchical organization and local configuration of the concepts. In contrast, concept mapping also let unintended and scientifically incorrect notions become ingrained and go unchallenged. On the basis of the outcomes of our study we formulated specific recommendations for the use of concept maps in the classroom. These include continued instruction in establishing proper hierarchies and cross-links to increase the quality of the concept maps' structure and the number of high quality links. Then, instruction should facilitate students' attempts to reflect on the nature of the relationships expressed in their maps. And finally, specific roles could be assigned to individual students to improve the overall quality of the process of constructing the map and, thus, of the final product.

Making clinical case-based learning in veterinary medicine visible: analysis of collaborative concept-mapping processes and reflections.  

Science.gov (United States)

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

Attitudes to concept maps as a teaching/learning activity in undergraduate health professional education: influence of preferred learning style.  

Science.gov (United States)

Concept maps that integrate and relate concepts in a nonlinear fashion are widely accepted as an educational tool that can underpin meaningful learning in medical education. However, student take-up may be affected by a number of cognitive and non-cognitive influences. In the present study, student attitudes to pre-prepared concept maps introduced in Stage 2 conjoint MPharm and BSc Pharmacology lectures were examined in relation to preferred learning styles according to the Felder-Silverman model. There was no statistically significant influence of dichotomous learning style dimension (sensing/intuitive; visual/verbal; active/reflector; sequential/global) on the self-reported utility of such concept maps to learning. However, when strength of preference was analysed within each dimension, moderate/strong verbal learners were found to be significantly less likely to self-report concept maps as useful relative to mild verbal learners. With this important exception, these data now suggest that student attitudes to concept maps are broadly not influenced by preferred learning styles and furthermore highlight the potential of concept maps to address a variety of different learning styles and thereby facilitate 'teaching to all types'. Concept maps could therefore potentially assist motivation, engagement and deep learning in medical and biomedical science education when used as a supplement to more traditional teaching/learning activities.

Synthesis of multiple antigenic peptides (MAPs)-strategies and limitations.  

Science.gov (United States)

Dendrimeric platforms such as MAPs can be synthesized either entirely by solid-phase methods (SPPS, direct approach) or by conjugation in solution of preformed, SPPS-made building blocks (indirect approach). Although MAPs and MAP-like constructs have been extensively and successfully used for various biological (mainly immunological) applications, experimental reports are most often lacking in chemical detail about their preparation and characterization. Here, we provide complete accounts of the synthesis and analytical documentation of MAPs and similar dendrimers by either all-SPPS (direct) or chemoselective thioether ligation (indirect) methods. We have chosen as model epitopes a 24-residue sequence of the ectodomain of protein M2 from influenza virus (M2e), which is found to be a rather challenging peptide epitope, and a far more manageable, shortened (12-residue) version of the same peptide. The advantages and shortcomings of both direct and indirect methods are discussed. PMID:21391284

An effective self-assessment based on concept map extraction from test-sheet for personalized learning  

Science.gov (United States)

Examination is a traditional way to assess learners' learning status, progress and performance after a learning activity. Except the test grade, a test sheet hides some implicit information such as test concepts, their relationships, importance, and prerequisite. The implicit information can be extracted and constructed a concept map for considering (1) the test concepts covered in the same question means these test concepts have strong relationships, and (2) questions in the same test sheet means the test concepts are relative. Concept map has been successfully employed in many researches to help instructors and learners organize relationships among concepts. However, concept map construction depends on experts who need to take effort and time for the organization of the domain knowledge. In addition, the previous researches regarding to automatic concept map construction are limited to consider all learners of a class, which have not considered personalized learning. To cope with this problem, this paper proposes a new approach to automatically extract and construct concept map based on implicit information in a test sheet. Furthermore, the proposed approach also can help learner for self-assessment and self-diagnosis. Finally, an example is given to depict the effectiveness of proposed approach.

Full Text Available Self-direction in learning and writing viable research proposals are considered by higher education institutions as essential skills for graduate students to start their careers as researchers. This is an evidence-based practice study focuses on the use of concept mapping to facilitate self-directed learning and enhance research proposal writing in teacher education. An action mixed methods research design was used in this study with quantitative and qualitative data. Participants were 29 graduate students who were enrolled in a core course aimed to provide learners with an in-depth understanding of research methods. All students, at the beginning of the course, were asked to write a research proposal and complete the Self-Directed Learning Readiness Scale (SDLRS. They then were given training in the use of concept mapping technique throughout the course to develop research proposals. Students’ scores prior to and after the intervention were compared. Results indicate that students developed significantly more concrete research proposals, and displayed higher scores at post-intervention assessment. Findings of this study value and support the use of concept mapping to provide students with a comprehensive understanding of the knowledge of their area of study as they reflect on every element of their proposals.

Systematic errors of mapping functions which are based on the VMF1 concept  

Science.gov (United States)

Precise GNSS positioning requires an accurate Mapping Function (MF) to model the tropospheric delay. To date the most accurate MF is the Vienna Mapping Function 1 (VMF1). It utilizes data from a numerical weather model which is known for high predictive skill (Integrated Forecast System of the European Centre of Medium range Weather Forecast). Still, the VMF1, or any other MF which is based on the VMF1 concept, is a parameterized mapping approach and this means that it is tuned for specific elevation angles, station and orbital altitudes. In this study we analyse the systematic errors caused by such tuning on a global scale. We find that in particular the parameterization of the station altitude dependency is a major concern regarding airborne applications. For the moment we do not provide an improved parameterized mapping approach to mitigate systematic errors but instead we propose a rapid direct and therefore error-free mapping approach; the so-called Potsdam Mapping Factors (PMFs).

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

Scientific Electronic Library Online (English)

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

New Trends in Astronomy Education: a ``Mapping" Strategy in Teaching and Learning Astronomy  

Science.gov (United States)

The application of a concept of educational ``science maps" to astronomy education is discussed. By analogy with geographical maps, scales of educational science maps -- scales of integration -- are introduced. In astronomy education, scale A represents the level of branches and fields of astronomy and astrophysics, where interconnections between various astronomical disciplines are shown. Scale B represents the level of hypotheses and theories, encompassing a significant segment of a field of astronomy. Scale C represents the level of structures and internal hierarchies, encompassing the ``geography" and ``anatomy" of the material systems and objects essential for a given astronomical discipline, as well as the principal notions and concepts it uses. Science maps of different scales are illustrated with initial examples exploring the application of this methodology in astronomy and astrophysics.

Pooling strategies for establishing physical genome maps using FISH.  

Science.gov (United States)

Often, in biological studies, it is necessary to identify an organism's chromosomes. In some organisms the individual chromosomes can be identified by staining procedures while many other species have a very large number of chromosomes, often of similar size, which defy identification by traditional staining methods. We have devised strategies, based on fluorescent in situ hybridization (FISH), which allow the assignment of a preset number of probes to each chromosome without prior chromosome identification. By hybridizing mixtures of probes labeled with different colored fluorescent molecules, the chromosomal origin of each probe can be determined. PMID:9385540

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)

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.

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

International Nuclear Information System (INIS)

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

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

Scientific Electronic Library Online (English)

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

NITARP: Measuring The Effectiveness of an Authentic Research Experience in Secondary Astronomy Education Through Concept Mapping  

Science.gov (United States)

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

A deconvolution map-making method for experiments with circular scanning strategies  

CERN Document Server

Aims. To investigate the performance of a deconvolution map-making algorithm for an experiment with a circular scanning strategy, specifically in this case for the analysis of Planck data, and to quantify the effects of making maps using simplified approximations to the true beams. Methods. We present an implementation of a map-making algorithm which allows the combined treatment of temperature and polarisation data, and removal of instrumental effects, such as detector time constants and finite sampling intervals, as well as the deconvolution of arbitrarily complex beams from the maps. This method may be applied to any experiment with a circular scanning-strategy. Results. Low-resolution experiments were used to demonstrate the ability of this method to remove the effects of arbitrary beams from the maps and to demonstrate the effects on the maps of ignoring beam asymmetries. Additionally, results are presented of an analysis of a realistic full-scale simulated data-set for the Planck LFI 30 GHz channel. Con...

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.

Efficient spatio-temporal hole filling strategy for Kinect depth maps  

Science.gov (United States)

In this paper we present an efficient hole filling strategy that improves the quality of the depth maps obtained with the Microsoft Kinect device. The proposed approach is based on a joint-bilateral filtering framework that includes spatial and temporal information. The missing depth values are obtained applying iteratively a joint-bilateral filter to their neighbor pixels. The filter weights are selected considering three different factors: visual data, depth information and a temporal-consistency map. Video and depth data are combined to improve depth map quality in presence of edges and homogeneous regions. Finally, the temporal-consistency map is generated in order to track the reliability of the depth measurements near the hole regions. The obtained depth values are included iteratively in the filtering process of the successive frames and the accuracy of the hole regions depth values increases while new samples are acquired and filtered.

Differential-associative processing or example elaboration: Which strategy is best for learning the definitions of related and unrelated concepts?  

Science.gov (United States)

Definitions of related concepts (e.g., genotype-phenotype) are prevalent in introductory classes. Consequently, it is important that educators and students know which strategy(s) work best for learning them. This study showed that a new comparative elaboration strategy, called differential-associative processing, was better for learning definitions of related concepts than was an integrative elaborative strategy, called example elaboration. This outcome occurred even though example elaboration was administered in a naturalistic way (Experiment 1) and students spent more time in the example elaboration condition learning (Experiments 1, 2, 3), and generating pieces of information about the concepts (Experiments 2 and 3). Further, with unrelated concepts (morpheme-fluid intelligence), performance was similar regardless if students used differential-associative processing or example elaboration (Experiment 3). Taken as a whole, these results suggest that differential-associative processing is better than example elaboration for learning definitions of related concepts and is as good as example elaboration for learning definitions of unrelated concepts.

The Effect of Concept Mapping on L2 Writing Performance: Examining Possible Effects of Trait-Level Writing Anxiety  

Directory of Open Access Journals (Sweden)

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

Gradient field mapping measurement concept demonstration with a geostationary severe storm imager (IFTS)  

Science.gov (United States)

A unifying theme throughout the ESE science objectives is the identification of regions with large temporal and spatial gradients. Severe storm formation occurs in the boundary regions between airmasses with very different temperatures, pressures, water content, aerosol loading. Severe storm tracking and forecasting utilizes the discontinuities in observed fields and gradient fields to diagnose and forecast the formation, evolution, and motion of severe storms. In a similar fashion, heat islands, super-regional pollution, and rain shower formation are each the result of temporal and spatial gradients present in the atmosphere. Diagnosing and forecasting these events requires an ability to map atmospheric gradients and discontinuities in real-time on micro to meso-scales in the atmosphere (0.5 - 500 km). A new measurement concept, the Imaging Fourier Transform Spectrometer (IFTS) is capable of demonstrating a class of autonomous event identification, monitoring and tracking sensors. In order to provide this capability a sensor with the ability to combine high spatial resolution (0.5 - 1 km) imaging with high spectral resolution (0.25 cm - 1 across the mid infrared 3 -10 microns) in time intervals of a few seconds is required. An electronically programmable infrared camera that combines a large-format focal plane array with a Fourier transform spectrometer can deliver this capability. It also builds on currently fielded airborne demonstration systems and an instrument concept in development for the Next Generation Space Telescope (NGST). The IFTS concept is revolutionary in several aspects. It can produce 2 - 10 fold increase in spatial resolution, 2 fold increases in spectral resolution, and 30 fold increases in temporal resolution. In combination the measurement concept would require a 100 - 600 fold increase in telemetry bandwidth without a new approach to imaging. IFTS breaks this paradigm with a new approach to hyperspectral imaging. Severe storm forecasting requires gradient fields (i.e., first and second derivatives of atmospheric observations). Hence, this measurement concept for IFTS is enabled by four innovations: (1) directly observe the derivative fields, (2) Nyquist sample the image plane to enable full utilization of the telescope performance, (3) have multi-channel detection of gradient regions, and (4) provide an autonomous targeting and tracking system that identifies, subsets, and follows regions with significant discontinuities (i.e., regions where severe storms, toxic pollution, heat islands, or rain/thunderstorms will form).

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

Directory of Open Access Journals (Sweden)

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

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

International Nuclear Information System (INIS)

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

Least-cost planning as a concept of control. New economic strategies for the rational use of electric energy  

International Nuclear Information System (INIS)

In the face of imminent climate change, reform concepts that are based on energy conservation are bound to prevail over other approaches. One such concept is that of Least Cost Planning (LCP). LCP aims at an unbiased choice among the options on the supply side (power plants, networks) and those on the demand side (energy conservation and substitution programmes). While today LCP is often discussed in a rather abbreviated sense as a concept for corporate strategies of power supply companies, the present paper develops it as a new concept for public control of power supply companies. An example of US American practice is analysed to determine to what extent the concept of LCP is compatible, in principle and practice, with a control system over power supply companies. This is used to develop elements for the reform of the German control system which would provide the economic dimension to the power supply companies' task of efficient energy utilisation. (orig.)

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

Science.gov (United States)

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

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.

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.

Data processing strategy of Raman chemical maps: data characteristics and behavior  

Science.gov (United States)

Raman maps, when acquired and processed successfully, produce Raman chemical images, which provide detailed information on the spatial distribution and morphology of individual chemical species in samples. The advantages of Raman chemical images are most significant when the sample is chemically and structurally complicated. In pharmaceutical applications, these Raman chemical images can be used to understand and develop drug formulations, drug delivery mechanisms, and drug-cellular interactions. Studies using Raman hyperspectral imaging - the term that encompasses the entire procedure from data measurement to processing and interpretation - is increasing and gaining a wider acceptance due to recent improvements in Raman instrumentation and software. Since Raman maps are a collection of numerous Raman spectra of different chemical species, within a single data set, spectral characteristics such as the scattering strength, fluorescence level, and baselines vary a great deal. To acquire and process a Raman map successfully, this heterogeneity must be taken into the consideration. This paper will show the impact of signal-to-noise ratio (S/N) on data processing strategies and their results. It will be demonstrated that the S/N of original data is critical for good classification and scientifically meaningful results regardless of the processing strategies.

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

Directory of Open Access Journals (Sweden)

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

Hepatitis C virus contact map prediction based on binary encoding strategy.  

Science.gov (United States)

Inter-residue contact map is an important two-dimensional representation of protein spatial structure, and has much potential application in the area of understanding protein fold mechanism. In the present note, a 19-bit binary input encoding strategy, integrating with residue pair conformational features (possible residue pairwise, residue classification, secondary structure, sequence length, and sequence separation information), is proposed for the purpose of capturing mapping relationship of protein sequence. Simulation results on a set of 61 hepatitis C virus (HCV) retrieved from the protein data bank (PDB) demonstrate that the proposed encoding scheme could precisely capture conformational patterns within HCV protein sequence. This promising result could provide some useful insights into the nature of HCV protein fold mechanism. PMID:17499551

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 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.

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.

Intervention mapping for the development of a strategy to implement the insurance medicine guidelines for depression  

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.

Formative use of select-and-fill-in concept maps in online instruction: Implications for students of different learning styles  

Science.gov (United States)

The purpose of this research was to investigate the formative use of Select and Fill-In (SAFI) maps in online instruction and the cognitive, metacognitive, and affective responses of students to their use. In particular, the implications of their use with students of different learning styles was considered. The research question investigated in this qualitative study was: How do students of different learning styles respond to online instruction in which SAFI maps are utilized? This question was explored by using an emergent, collective case study. Each case consisted of community college students who shared a dominant learning style and were enrolled in an online course in environmental studies. Cases in the study were determined using Kolb's Learning Style Inventory (LSI). Seven forms of data were collected during the study. During the first phase of data collection, dominant learning style and background information on student experience with concept mapping and online instruction was determined. In the second phase of data collection, participants completed SAFI maps and quiz items that corresponded to the content of the maps. Achievement data on the map activities and quiz and student responses to a post-SAFI survey and questionnaire were recorded to identify learner cognitive, metacognitive, and affective responses to the tasks. Upon completion of data collection, cases were constructed and compared across learning styles. Cases are presented using the trends, across participants sharing the same dominant learning style, in achievement, behaviors and attitudes as seen in the evidence present in the data. Triangulation of multiple data sources increased reliability and validity, through cross-case analyses, and produced a thick description of the relationship between the cases for each learning style. Evidence suggesting a cognitive response to the SAFI tasks was inconsistent across cases. However, learners with an affinity towards reflective learning activities demonstrated more positive metacognitive and affective responses to the SAFI tasks. This suggests that the contemplation and consideration of relationships expressed in the map requires learners, while completing the SAFI task, to compare their existing cognitive structure with an accepted structure and to reflect on the differences and similarities that may exist. Subsequently, the value of formative online SAFI map use for learners lies within the cognitive process of completing the tasks, not in the construction of an abstract cognitive structure reflecting an accepted structure and organization of concepts suggested by a completed map.

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

Science.gov (United States)

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

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

Science.gov (United States)

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

Language Learning Strategy Use and Concept Development among Jordanian Undergraduate English Language Majors  

Directory of Open Access Journals (Sweden)

Full Text Available This study investigated, for two continuous years, the level of use of foreign language learning strategies (FLLSs. It also investigated their development in terms of the study-semester and gender variables by 45 Jordanian undergraduate English Language Majors. The Strategy Inventory for Language Learning (SILL was used as an instrument for collecting the data necessary to answer the questions of the study. Appropriate statistical devices were employed to analyze the data. The findings revealed that Jordanian undergraduates majoring in English Language were High strategy users for most of the strategies. The Metacognitive strategies were ranked first followed by the Social, Compensation, Affective, Cognitive, and Memory strategies respectively. Differences between males’ and females’ responses were not significant in terms of the gender variable while the study-semester variable showed significant differences in favor of third and fourth semesters' responses. The findings were ascribed to a variety of factors such as: age, courses students study, determination to get high marks, and wide use of modern technology. The conclusions support the idea of unconscious learning of FLLSs through long exposure to English Language courses and students' preference of Metacognitive strategies.

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

Energy Technology Data Exchange (ETDEWEB)

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.

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

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.

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

Ligand efficiency indices for an effective mapping of chemico-biological space: the concept of an atlas-like representation.  

Science.gov (United States)

We propose a numerical framework that permits an effective atlas-like representation of chemico-biological space based on a series of Cartesian planes mapping the ligands with the corresponding targets connected by an affinity parameter (K(i) or related). The numerical framework is derived from the concept of ligand efficiency indices, which provide a natural coordinate system combining the potency toward the target (biological space) with the physicochemical properties of the ligand (chemical space). This framework facilitates navigation in the multidimensional drug discovery space using map-like representations based on pairs of combined variables related to the efficiency of the ligands per Dalton (molecular weight or number of non-hydrogen atoms) and per unit of polar surface area (or number of polar atoms).

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

Directory of Open Access Journals (Sweden)

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

Reconstructing Genome-Wide Protein–Protein Interaction Networks Using Multiple Strategies with Homologous Mapping  

Science.gov (United States)

Background One of the crucial steps toward understanding the biological functions of a cellular system is to investigate protein–protein interaction (PPI) networks. As an increasing number of reliable PPIs become available, there is a growing need for discovering PPIs to reconstruct PPI networks of interesting organisms. Some interolog-based methods and homologous PPI families have been proposed for predicting PPIs from the known PPIs of source organisms. Results Here, we propose a multiple-strategy scoring method to identify reliable PPIs for reconstructing the mouse PPI network from two well-known organisms: human and fly. We firstly identified the PPI candidates of target organisms based on homologous PPIs, sharing significant sequence similarities (joint E-value ? 1 × 10?40), from source organisms using generalized interolog mapping. These PPI candidates were evaluated by our multiple-strategy scoring method, combining sequence similarities, normalized ranks, and conservation scores across multiple organisms. According to 106,825 PPI candidates in yeast derived from human and fly, our scoring method can achieve high prediction accuracy and outperform generalized interolog mapping. Experiment results show that our multiple-strategy score can avoid the influence of the protein family size and length to significantly improve PPI prediction accuracy and reflect the biological functions. In addition, the top-ranked and conserved PPIs are often orthologous/essential interactions and share the functional similarity. Based on these reliable predicted PPIs, we reconstructed a comprehensive mouse PPI network, which is a scale-free network and can reflect the biological functions and high connectivity of 292 KEGG modules, including 216 pathways and 76 structural complexes. Conclusions Experimental results show that our scoring method can improve the predicting accuracy based on the normalized rank and evolutionary conservation from multiple organisms. Our predicted PPIs share similar biological processes and cellular components, and the reconstructed genome-wide PPI network can reflect network topology and modularity. We believe that our method is useful for inferring reliable PPIs and reconstructing a comprehensive PPI network of an interesting organism. PMID:25602759

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.

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 lmall-scale out-of-pile mockup testing in loops, middle-scale TBMs testing in EAST, the superconducting tokamak in China, severing as a pre-testing platform for TBM prior to ITER, because the major parameters of EAST are comparable to those of ITER (for EAST, BT 3.5 ? 4T, D-D neutron rate = 1015 ? 1017 n/sec, average heat flux on the FW = 0.1 ? 0.2 MW/m2, port size = 0.97 x 0.53 m2, plasma pulse length = ? 1000 sec), and full-scale consecutive TBMs corresponding to different operation phases of ITER during the first 10 years. Design details on TBM concept, such as structure scenarios, auxiliary systems, performances analyses and testing strategy combining TBMs testing, in sequence and in parallel, in EAST and ITER, are presented in this contribution.

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.

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

Science.gov (United States)

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

A configuração das imagens dos gestores sobre o conceito de estratégia / Images configuration of the managers about the strategy concept  

Scientific Electronic Library Online (English)

Full Text Available SciELO Brazil | Language: Portuguese Abstract in portuguese A forma como os gestores definem e implementam estratégias também depende das imagens que eles possuem do conceito de estratégia. Assim, este trabalho tem como objetivo identificar as imagens de estratégia na percepção dos gestores. Entende-se que as imagens estão organizadas como uma rede de signif [...] icados ou esquemas associados. Essas imagens também se organizam em torno de alguns elementos centrais, que são socialmente aceitos e compartilhados. A identificação das imagens mentais que os gestores têm a respeito de estratégia é relevante para aprofundar a compreensão das práticas organizacionais adotadas em um determinado ambiente competitivo. Com base nas cinco dimensões propostas por Mintzberg (1987) e no método de configuração da imagem (MCI), procurou-se identificar, em uma amostra de 46 gestores, qual a imagem coletiva de estratégia destes. Abstract in english The form as the managers defines and implements strategies also depends on the images that they have about the strategy concept. Thus, this work has as objective to identify the strategy images in the managers' perception.

A map to a new treasure island: the human genome and the concept of common heritage.  

Science.gov (United States)

While the 1970's have been called the environmental years, the 1990's could be seen as the genome years. As the challenge to map and to sequence the human genome mobilized the scientific community, risks and benefits of information and uses that would derive from this project have also raised ethical issues at the international level. The particular interest of the 1997 UNESCO Declaration relies on the fact that it emphasizes both the scientific importance of genetics and the appropriate reinforcement of human rights in this area. It considers the human genome, at least symbolically, as the common heritage of humanity. PMID:9736186

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

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

DEFF Research Database (Denmark)

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

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

Energy Technology Data Exchange (ETDEWEB)

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

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.

Work with groups in Family Health: concepts, structure and strategies for transcultural care. A qualitative study  

Directory of Open Access Journals (Sweden)

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

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

International Nuclear Information System (INIS)

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

New Landscape Planning Concepts to Management Strategies for Developing Agricultural Regions  

Directory of Open Access Journals (Sweden)

Full Text Available Sustainable land resource management depends on the good assessment and planning of current landscapes. This may be possible with application of multidisciplinary researches, as this study presented a multidisciplinary approach in a spatial database frame work using Geographic Information System. ?Agroecological zones? concept is used to integrating and characterizing homogenous spatial units. This approach combine theme layers include of available water resources, climate, terrain and soil conditions, associated with land use and settlement patterns. Climatic indices layers, including of growing degree days, aridity index, length of growing period and freezing period were created using the correlation between climatic parameter and digital elevation model. Using this approach the Borujen watershed was divided in 28 ?agroecological zones? which defined 3 landscapes or agricultural regions. The most important constraints for developing agriculture in landscape I has topographic, climatic and soil constrains, landscape II has topographic and soil constrains and landscape III has the some limitations of soil. Landscape I and II are much less attractive from an agricultural perspective. Landscape III is suitable for agriculture but, the potential for rainfed cropping system is limited by a lack of growing period during which neither temperature nor moisture is limiting to plant production. In general, the case study of the Borujen watershed indicated that this approach can be used for different scales and adaptive to the particular planning.

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

International Nuclear Information System (INIS)

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

Enhancement of the remote handling strategy for the refurbishment of the backplate bayonet concept of IFMIF target system  

Energy Technology Data Exchange (ETDEWEB)

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

This operation has a strong impact on the intervention time for the backplate refurbishment which has to be repeated at least every year. Consequently the need to update the RH strategy for the refurbishment of this component becomes a precondition in order to fulfill the stringent requirement to enhance the duty cycle of IFMIF plant. In this paper two potential approaches are presented: the first relies on the possibility to perform all the refurbishment operations in situ in the test cell cavern, whilst the second one foresees to perform these operations off-line in a hot cell. Advantages and disadvantages of these approaches together with the RH requirements for the refurbishment operations of the backplate bayonet concepts are also reported.

Developing An Effective Strategy to Configure Assembly Systems Using Lean Concepts  

Directory of Open Access Journals (Sweden)

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

Current Concepts in Therapeutic Strategies Targeting Cognitive Decline and Disease Modification in Alzheimer’s Disease  

Science.gov (United States)

Summary: Alzheimer’s disease is a progressive neurodegenerative disorder and the leading cause of dementia in the Western world. Postmortem, it is characterized neuropathologically by the presence of amyloid plaques, neurofibrillary tangles, and a profound gray matter loss. Neurofibrillary tangles are composed of an abnormally hyperphosphorylated intracellular protein called tau, tightly wound into paired helical filaments and thought to impact microtubule assembly and protein trafficking, resulting in the eventual demise of neuronal viability. The extracellular amyloid plaque deposits are composed of a proteinacious core of insoluble aggregated amyloid-? (A?) peptide and have led to the foundation of the amyloid hypothesis. This hypothesis postulates that A? is one of the principal causative factors of neuronal death in the brains of Alzheimer’s patients. With multiple drugs now moving through clinical development for the treatment of Alzheimer’s disease, we will review current and future treatment strategies aimed at improving both the cognitive deficits associated with the disease, as well as more novel approaches that may potentially slow or halt the deadly neurodegenerative progression of the disease.

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

Directory of Open Access Journals (Sweden)

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

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

DEFF Research Database (Denmark)

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

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

Directory of Open Access Journals (Sweden)

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

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

Directory of Open Access Journals (Sweden)

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

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

International Nuclear Information System (INIS)

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

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)

A possible strategy based on final disposal of unreprocessed spent nuclear fuel - the Swedish KBS-3 concept  

International Nuclear Information System (INIS)

The Swedish policy on management of the main bulk of spent nuclear fuel is based on direct disposal without reprocessing. This will give Sweden very flexible possibilities of handling the spent fuel within the country. Technical characteristics and the safety of a once-through strategy of the nuclear fuel cycle have been studied since 1977. A sea-transportation system is now in operation and a central facility for intermediate wet storage of spent fuel will be taken into operation in 1985. The system under study comprises encapsulation of spent fuel in copper canisters after 40 years of intermediate storage, and final storage of these canisters in Swedish crystalline bedrock. It has been concluded that this concept for final disposal of spent unreprocessed fuel is technically feasible and acceptable with respect to safety and radiation protection. At present reprocessing has no advantages over direct disposal in the limited nuclear program of Sweden. The intermediate storage of spent fuel will in practice allow for a continuous re-evaluation of alternative or modified and optimized systems for spent fuel management before a final choice is made

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

Directory of Open Access Journals (Sweden)

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

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

Science.gov (United States)

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

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

Science.gov (United States)

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

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

Directory of Open Access Journals (Sweden)

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

A Gibbs sampling strategy applied to the mapping of ambiguous short-sequence tags  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Motivation: Chromatin immunoprecipitation followed by high-throughput sequencing (ChIP-seq) is widely used in biological research. ChIP-seq experiments yield many ambiguous tags that can be mapped with equal probability to multiple genomic sites. Such ambiguous tags are typically eliminated from consideration resulting in a potential loss of important biological information.

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

Directory of Open Access Journals (Sweden)

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

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

International Nuclear Information System (INIS)

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

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

Directory of Open Access Journals (Sweden)

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

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

Directory of Open Access Journals (Sweden)

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

Full Text Available SciELO Brazil | Language: Portuguese Abstract in portuguese A utilização dos mapas conceituais (MCs) como ferramenta de avaliação da aprendizagem foi explorada na disciplina Ciências da Natureza, oferecida aos alunos ingressantes da Escola de Artes, Ciências e Humanidades (EACH). Devido à riqueza e à diversidade das estruturas proposicionais elaboradas pelos [...] alunos, o desafio de corrigir MCs é mais complexo do que a correção de testes de múltipla escolha ou de questões dissertativas. Um procedimento comparativo envolvendo o professor (P), três especialistas em mapeamento conceitual (E) e os alunos (A) foi utilizado para avaliar MCs (n = 109). A pergunta focal dos MCs explorou as relações conceituais entre as observações astronômicas do século XVI, o nascimento da ciência moderna e a ampliação da nossa compreensão sobre o universo. Gráficos de correlação foram elaborados para comparar as avaliações (PxE, PxA e ExA). Os resultados obtidos confirmaram a complexidade do processo de avaliação dos MCs, impondo uma mudança nos procedimentos usualmente adotados na sala de aula. A possibilidade dos alunos serem incluídos no processo avaliativo é confirmada pela correlação verificada entre as avaliações feitas pelo professor e pelos alunos. Abstract in english The use of concept maps (CMs) as an evaluation tool of students' learning was explored during the Natural Science course assigned to all 1styear higher education students at School of Arts, Sciences and Humanities (University of São Paulo). The richness and diversity of propositional networks produc [...] ed by the students made the assessment task more complex than the evaluation of multiple-choice tests or open questions. A procedure for comparing the evaluation made by the professor (P), three experts in CMs (E) and the students (S) was used to appraise a set of CMs (n = 109). CMs' focal question explored the conceptual relationships among astronomic observations made during the 16$^{th}$ century, the birth of modern science and, the increase of our understanding about the universe. Correlation graphs were plotted to compare these evaluations in pairs (PxE, PxS and ExS). The results confirmed the complexity of the MCs evaluation, which asks for changing the procedures frequently used in the classroom. The possibility of including the students in the evaluation process is confirmed by the correlation found between the assessments made by them and the professor.

Strategies for haplotype-based association mapping in complex pedigreed populations  

DEFF Research Database (Denmark)

In association mapping, haplotype-based methods are generally regarded to provide higher power and increased precision than methods based on single markers. For haplotype-based association mapping most studies use a fixed haplotype effect in the model. However, an increase in haplotype length increases the number of parameters in the model, resulting in low accuracy of the estimates especially for the low-frequency haplotypes. Modeling of haplotype effects can be improved if they are assumed to be random effects, as only one parameter i.e. haplotype variance needs to be estimated compared to estimating the effects of all different haplotypes in a fixed haplotype model. Using simulated data, we investigated statistical models where haplotypes were fitted either as a fixed or random effect and we compared them for the power, precision, and type I error. We investigated five haplotype lengths of 2, 4, 6, 10 and 20. The simulated data resembled the Danish Holstein cattle pedigree representing a complex relationship structure and QTL effects of different sizes were simulated. We observed that the random haplotype models had high power and very low type I error rates (after Bonferroni correction), while the fixed haplotype models had lower power and excessively high type I errors. A haplotype length of 4 to 6 gave the best results for random model in the present study. Though the present study was conducted on data structure more frequent in livestock, our findings on random vs. fixed haplotype effects in association mapping models are applicable to data from other species with similar pedigree structure

Gains in power for exhaustive analyses of haplotypes using variable-sized sliding window strategy: a comparison of association-mapping strategies.  

Science.gov (United States)

Linkage disequilibrium (LD)-based association mapping is often performed by analyzing either individual SNPs or block-based multi-SNP haplotypes. Sliding windows of several fixed sizes (in terms of SNP numbers) were also applied to a few simulated or real data sets. In comparison, exhaustively testing based on variable-sized sliding windows (VSW) of all possible sizes of SNPs over a genomic region has the best chance to capture the optimum markers (single SNPs or haplotypes) that are most significantly associated with the traits under study. However, the cost is the increased number of multiple tests and computation. Here, a strategy of VSW of all possible sizes is proposed and its power is examined, in comparison with those using only haplotype blocks (BLK) or single SNP loci (SGL) tests. Critical values for statistical significance testing that account for multiple testing are simulated. We demonstrated that, over a wide range of parameters simulated, VSW increased power for the detection of disease variants by approximately 1-15% over the BLK and SGL approaches. The improved performance was more significant in regions with high recombination rates. In an empirical data set, VSW obtained the most significant signal and identified the LRP5 gene as strongly associated with osteoporosis. With the use of computational techniques such as parallel algorithms and clustering computing, it is feasible to apply VSW to large genomic regions or those regions preliminarily identified by traditional SGL/BLK methods.

Exploring NoC Mapping Strategies: An Energy and Timing Aware Technique  

CERN Document Server

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

Global mapping of herpesvirus-host protein complexes reveals a transcription strategy for late genes.  

Science.gov (United States)

Mapping host-pathogen interactions has proven instrumental for understanding how viruses manipulate host machinery and how numerous cellular processes are regulated. DNA viruses such as herpesviruses have relatively large coding capacity and thus can target an extensive network of cellular proteins. To identify the host proteins hijacked by this pathogen, we systematically affinity tagged and purified all 89 proteins of Kaposi's sarcoma-associated herpesvirus (KSHV) from human cells. Mass spectrometry of this material identified over 500 virus-host interactions. KSHV causes AIDS-associated cancers, and its interaction network is enriched for proteins linked to cancer and overlaps with proteins that are also targeted by HIV-1. We found that the conserved KSHV protein ORF24 binds to RNA polymerase II and brings it to viral late promoters by mimicking and replacing cellular TATA-box-binding protein (TBP). This is required for herpesviral late gene expression, a complex and poorly understood phase of the viral lifecycle. PMID:25544563

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

Directory of Open Access Journals (Sweden)

Full Text Available

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

The effectiveness of teaching strategies for creativity in a nursing concepts teaching protocol on the creative thinking of two-year RN-BSN students.  

Science.gov (United States)

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

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

Science.gov (United States)

Recently, manifold dynamics has assumed an increasing relevance for analysis and design of low-energy missions, both in the Earth-Moon system and in alternative multibody environments. With regard to lunar missions, exterior and interior transfers, based on the transit through the regions where the collinear libration points L1 and L2 are located, have been studied for a long time and some space missions have already taken advantage of the results of these studies. This paper is focused on the definition and use of a special isomorphic mapping for low-energy mission analysis. A convenient set of cylindrical coordinates is employed to describe the spacecraft dynamics (i.e. position and velocity), in the context of the circular restricted three-body problem, used to model the spacecraft motion in the Earth-Moon system. This isomorphic mapping of trajectories allows the identification and intuitive representation of periodic orbits and of the related invariant manifolds, which correspond to tubes that emanate from the curve associated with the periodic orbit. Heteroclinic connections, i.e. the trajectories that belong to both the stable and the unstable manifolds of two distinct periodic orbits, can be easily detected by means of this representation. This paper illustrates the use of isomorphic mapping for finding (a) periodic orbits, (b) heteroclinic connections between trajectories emanating from two Lyapunov orbits, the first at L1, and the second at L2, and (c) heteroclinic connections between trajectories emanating from the Lyapunov orbit at L1 and from a particular unstable lunar orbit. Heteroclinic trajectories are asymptotic trajectories that travels at zero-propellant cost. In practical situations, a modest delta-v budget is required to perform transfers along the manifolds. This circumstance implies the possibility of performing complex missions, by combining different types of trajectory arcs belonging to the manifolds. This work studies also the possible application of manifold dynamics to defining suitable, convenient end-of-life strategies for spacecraft orbiting the Earth. Seven distinct options are identified, and lead to placing the spacecraft into the final disposal orbit, which is either (a) a lunar capture orbit, (b) a lunar impact trajectory, (c) a stable lunar periodic orbit, or (d) an outer orbit, never approaching the Earth or the Moon. Two remarkable properties that relate the velocity variations with the spacecraft energy are employed for the purpose of identifying the optimal locations, magnitudes, and directions of the velocity impulses needed to perform the seven transfer trajectories. The overall performance of each end-of-life strategy is evaluated in terms of time of flight and propellant budget.

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

Digital Repository Infrastructure Vision for European Research (DRIVER)

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 crit...

The analytical calibration in (bio)imaging/mapping of the metallic elements in biological samples--definitions, nomenclature and strategies: state of the art.  

Science.gov (United States)

Nowadays, studies related to the distribution of metallic elements in biological samples are one of the most important issues. There are many articles dedicated to specific analytical atomic spectrometry techniques used for mapping/(bio)imaging the metallic elements in various kinds of biological samples. However, in such literature, there is a lack of articles dedicated to reviewing calibration strategies, and their problems, nomenclature, definitions, ways and methods used to obtain quantitative distribution maps. The aim of this article was to characterize the analytical calibration in the (bio)imaging/mapping of the metallic elements in biological samples including (1) nomenclature; (2) definitions, and (3) selected and sophisticated, examples of calibration strategies with analytical calibration procedures applied in the different analytical methods currently used to study an element's distribution in biological samples/materials such as LA ICP-MS, SIMS, EDS, XRF and others. The main emphasis was placed on the procedures and methodology of the analytical calibration strategy. Additionally, the aim of this work is to systematize the nomenclature for the calibration terms: analytical calibration, analytical calibration method, analytical calibration procedure and analytical calibration strategy. The authors also want to popularize the division of calibration methods that are different than those hitherto used. This article is the first work in literature that refers to and emphasizes many different and complex aspects of analytical calibration problems in studies related to (bio)imaging/mapping metallic elements in different kinds of biological samples.

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

DEFF Research Database (Denmark)

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

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

Science.gov (United States)

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

Analisa-se o caso do consumo de um eletrodoméstico - tanquinho (máquina de lavar menos sofisticada) pela população de baixa renda. Assim, realizou-se uma pesquisa de campo em lojas de varejo com consumidores de baixa renda na cidade de São Paulo, no último trimestre de 2005. Os dados primários assim obtidos foram submetidos à análise através da utilização de técnicas estatísticas. Os resultados do trabalho mostram que o atendimento aos mercados populares não se consubstancia apenas com a adoção de estratégias genéricas de baixo custo. Necessita-se adotar uma estratégia de adequação, fit strategy, que se configura pelo equilíbrio entre a busca por ofertar melhores preços e o atendimento das necessidades do consumidor de baixa renda.

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

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

International Nuclear Information System (INIS)

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

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

Science.gov (United States)

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

The office visit and the self-help concept in treating the patient with psoriasis: a strategy revisited.  

Science.gov (United States)

All dermatologists and physicians who care for patients with psoriasis should be aware that their patients may have an insufficient understanding of their disease. Every effort should be made to help patients fully comprehend their condition: to become aware of factors that can improve self-care and environmental events that can exacerbate the disorder. Strategies for self-help instructions can be modified from the highly structured approach in a university setting to the more informal atmosphere of a physician's office using the abundant patient educational resources available today. Improving communication between patient and physician will benefit the patient, by providing knowledge about psoriasis, encouraging the patient to acquire specific skills in dealing with the disease, and instilling a sense of responsibility for the patient's involvement in self-care.

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

Science.gov (United States)

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

Investigating the Ocean-Climate System, Concept by Concept  

Science.gov (United States)

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

O presente trabalho tem como objetivo propor a Análise de Vizinhança (AViz) como uma forma inovadora de avaliar os MCs obtidos em sala de a [...] ula. A seleção de um Conceito Obrigatório (CO) permite ao professor verificar como os alunos o relacionam com outros conceitos, os quais são classificados como Conceitos Vizinhos (CVs). As proposições estabelecidas entre o CO e os CVs são suficientes para indicar o nível de compreensão do aluno sobre o tema mapeado. MCs (n = 69) sobre mudanças climáticas formam o primeiro conjunto de dados empíricos que ratifica o potencial da AViz. O CO selecionado foi dispersão, a fim de avaliar se os alunos conseguem relacionar esse fenômeno físico com o caráter global desse problema ambiental. Os padrães identificados a partir da AViz sugerem que, apesar de serem submetidos a uma mesma sequência didática, nem todos os alunos conseguiram utilizar o CO de forma adequada. Isso pode ser explicado a partir da Teoria da Aprendizagem Significativa de David Ausubel, que destaca o papel fundamental dos conhecimentos prévios no processo de assimilação de novas informações. Abstract in english The deep analysis of Concept Maps (Cmaps) may reveal latent information that is not perceived from the simple reading of its propositional network. This paper proposes the Neighborhood Analysis (NeAn) as an innovative way to assess the Cmaps obtained in a classroom. The selection of a Compulsory Con [...] cept (CC) allows teachers to evaluate how the students relate it to other concepts, which are classified as Neighbor Concepts (NCs). The propositions established between the CC, and the NCs are enough to indicate the students' level of understanding on the mapped subject. Cmaps (n = 69) about climate change are the first set of empirical data that confirms the potential of NeAn. Dispersion was selected as CC in order to check whether students can relate this physical phenomenon with the global perspective of climate change. The patterns found from the NeAn suggest that, despite being exposed to the same didactic activities, some students could not use the CC properly. This may be explained from David Ausubel's learning theory, which stresses the critical role of prior knowledge in the assimilation process of new information.

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

Science.gov (United States)

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

“CLASSIC NMR”: An In-Situ NMR Strategy for Mapping the Time-Evolution of Crystallization Processes by Combined Liquid-State and Solid-State Measurements**  

Science.gov (United States)

A new in-situ NMR strategy (termed CLASSIC NMR) for mapping the evolution of crystallization processes is reported, involving simultaneous measurement of both liquid-state and solid-state NMR spectra as a function of time. This combined strategy allows complementary information to be obtained on the evolution of both the solid and liquid phases during the crystallization process. In particular, as crystallization proceeds (monitored by solid-state NMR), the solution state becomes more dilute, leading to changes in solution-state speciation and the modes of molecular aggregation in solution, which are monitored by liquid-state NMR. The CLASSIC NMR experiment is applied here to yield new insights into the crystallization of m-aminobenzoic acid. PMID:25044662

Gains in power for exhaustive analyses of haplotypes using variable-sized sliding window strategy: a comparison of association-mapping strategies  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Linkage disequilibrium (LD)-based association mapping is often performed by analyzing either individual SNPs or block-based multi-SNP haplotypes. Sliding windows of several fixed sizes (in terms of SNP numbers) were also applied to a few simulated or real data sets. In comparison, exhaustively testing based on variable-sized sliding windows (VSW) of all possible sizes of SNPs over a genomic region has the best chance to capture the optimum markers (single SNPs or haplotypes) that are most sig...

A brief review of spatial analysis concepts and tools used for mapping, containment and risk modelling of infectious diseases and other illnesses.  

Science.gov (United States)

Fast response and decision making about containment, management, eradication and prevention of diseases, are increasingly important aspects of the work of public health officers and medical providers. Diseases and the agents causing them are spatially and temporally distributed, and effective countermeasures rely on methods that can timely locate the foci of infection, predict the distribution of illnesses and their causes, and evaluate the likelihood of epidemics. These methods require the use of large datasets from ecology, microbiology, health and environmental geography. Geodatabases integrating data from multiple sets of information are managed within the frame of geographic information systems (GIS). Many GIS software packages can be used with minimal training to query, map, analyse and interpret the data. In combination with other statistical or modelling software, predictive and spatio-temporal modelling can be carried out. This paper reviews some of the concepts and tools used in epidemiology and parasitology. The purpose of this review is to provide public health officers with the critical tools to decide about spatial analysis resources and the architecture for the prevention and surveillance systems best suited to their situations.

A Study on Strategy Instruction and EFL Learners’ Writing Skill  

Directory of Open Access Journals (Sweden)

Full Text Available Writing in a second or foreign language seems to be the most difficult language skill for language learners to acquire in academic contexts. While explicit instruction of strategies is not a usual practice in foreign language classrooms, it could be beneficial for language learners. The present study aims at investigating the effect of concept mapping strategy on EFL learners' writing performance. To this end, sixty Iranian students at the intermediate level of language proficiency participated in the study. Their language proficiency was determined by Michigan Test of English Language Proficiency. The results of the Analysis of Covariance revealed that the instruction of concept mapping strategy had a positive effect on EFL learners’ writing achievements. The findings have some pedagogical implications for teaching language skills and designing strategy-based syllabus leading to successful language performance.

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

Scientific Electronic Library Online (English)

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

Concept Mapping zur Unterstützung der differentialdiagnostischen Hypothesenbildung im fallbasierten Online-Lernsystem CASUS: Qualitative Verbesserung der Diagnosefindung durch ICD-10 Kodierung [Concept mapping for supporting the differential diagnostic generation of hypotheses in the case-based online learning system CASUS: Qualitative improvement of dagnostic performance through ICD-10 coding  

Directory of Open Access Journals (Sweden)

Full Text Available [english] Introduction: Concept mapping tools have long been established in medical education as an aid for visualizing learning processes in computer-based programs. The case-based learning system CASUS with its mapping tool for visualizing the differential diagnostic reasoning process is an example. It was shown that such tools are well accepted by users and lead to an increased number of diagnostic hypotheses being visualized as maps. However, there is scarce evidence on the quality of user-generated diagnostic hypotheses. This study examines the quality of diagnostic hypotheses obtained with CASUS and whether the quality can be improved through ICD-10 coding as compared with an expert’s solution. Methods: We randomized 192 third-year medical students at the University of Munich into two groups. The students worked in groups of two on one computer. Group A was asked to code their diagnostic hypotheses with an ICD-10 coding browser before entering them into the mapping tool. Group B generated their hypotheses without prior ICD-10 coding. The differential diagnostic reasoning visualizations were analyzed quantitatively and qualitatively. An expert solution was used as reference. Results: Eighty-seven differential diagnoses were evaluated. Group A, using ICD-10 coding, made the correct and precise diagnosis of malaria tropica significantly more often than Group B (p < 0.05. For additional alternative diagnostic hypotheses, no quantitative or qualitative differences were detected. Conclusions: ICD-10 coding in connection with a mapping tool supporting the diagnostic reasoning process improved the accuracy of diagnostic performance in third-year medical students in the case of malaria tropica. [german] Einleitung: Der Einsatz von Concept-Mapping-Tools in computergestützten Lernprogrammen ist in der medizinischen Ausbildung etabliert: Es konnte gezeigt werden, dass diese Werkzeuge zur Visualisierung von Differentialdiagnosen vom Anwender akzeptiert werden und zu einer vermehrten Hypothesenbildung beitragen. Es gibt bisher jedoch wenige Erkenntnisse über die Qualität der dabei vom Anwender erstellten Hypothesen. Die vorliegende Studie untersucht die Qualität der im Netzwerk-Tool im fallbasierten Lernsystem CASUS erstellten Hypothesen und inwieweit diese durch Kodierung mittels ICD10 präzisiert werden können. Methodik: Die Lernenden bearbeiteten zu zweit einen Computerlernfall zum Thema Malaria. Wir randomisierten 192 Teilnehmer der Studie aus dem 3. Studienjahr an der Universität München in zwei Gruppen: Gruppe A wurde gebeten, die erdachten Hypothesen vor der Eingabe in das Netzwerk-Tool mittels eines ICD10-Browsers zu kodieren. Gruppe B erstellte ihre Hypothesen ohne weitere Hilfsmittel. Die Netzwerke wurden quantitativ und qualitativ evaluiert und die Ergebnisse der beiden Gruppen verglichen. Als Referenz diente das von Experten erstellte Netzwerk. Ergebnisse: 87 differentialdiagnostische Netzwerke konnten ausgewertet werden. In Gruppe A mit ICD10-Kodierung der Hypothesen, konnten die Lernenden signifikant häufiger (p<0,005 die exakte Hauptdiagnose Malaria tropica stellen. In der Gruppe ohne ICD10 Kodierung wurde signifikant häufiger (p<0,005 die unpräzise Diagnose "Malaria" gestellt. Für die Nebendiagnosen ergaben sich qualitativ und quantitativ keine Unterschiede. Schlussfolgerungen: Die ICD10-Kodierung der Hypothesen im Netzwerk-Tool führte zu einer präziseren Diagnosestellung der Studierenden im klinischen Studienabschnitt. Die Integration eines ICD-Browsers zur Unterstützung der differentialdiagnostischen Hypothesenbildung in fallbasierten Lernsystemen ist sinnvoll.

A note on the efficiencies of sampling strategies in two-stage Bayesian regional fine mapping of a quantitative trait.  

Science.gov (United States)

In focused studies designed to follow up associations detected in a genome-wide association study (GWAS), investigators can proceed to fine-map a genomic region by targeted sequencing or dense genotyping of all variants in the region, aiming to identify a functional sequence variant. For the analysis of a quantitative trait, we consider a Bayesian approach to fine-mapping study design that incorporates stratification according to a promising GWAS tag SNP in the same region. Improved cost-efficiency can be achieved when the fine-mapping phase incorporates a two-stage design, with identification of a smaller set of more promising variants in a subsample taken in stage 1, followed by their evaluation in an independent stage 2 subsample. To avoid the potential negative impact of genetic model misspecification on inference we incorporate genetic model selection based on posterior probabilities for each competing model. Our simulation study shows that, compared to simple random sampling that ignores genetic information from GWAS, tag-SNP-based stratified sample allocation methods reduce the number of variants continuing to stage 2 and are more likely to promote the functional sequence variant into confirmation studies.

Performing Mimetic Mapping: A Non-Visualisable Map of the Suzhou River Area of Shanghai  

Directory of Open Access Journals (Sweden)

Full Text Available This paper questions issues concerning the mapping of experience, through the concept of mimesis – the creative re-performance of the site experience onto the map. The place mapped is the Suzhou River area, a significant part of Shanghai, the former boundary between the British and American Settlements, and an ever-changing and transforming territory. Through the detailed description of the mapping processes, we analyse the position of this particular map within contemporary discourse about mapping. Here, we question the purpose of the process, the desired outcome, the consciousness of the significance of each step/event, and the possible significance of the final traces that the mapping leaves behind. Although after the mapping had been carried out, the procedure was analysed, post-rationalised, and justified through its partial documentation (as part of an educational process, this paper questions the way and the reason for these practices (the post-rationalising of the mapping activity, justifying the strategy, etc., and their possible meaning, purpose, demand or context. Thus we conclude that the subject matter is not the final outcome of an object or ‘map’; there is no final map to be exhibited. What this paper brings forth is the mapping as an event, an action performed by the embodied experience of the actual place and by the trans-local materiality of the tools and elements involved in the process of its making.

LaSSO, a strategy for genome-wide mapping of intronic lariats and branch points using RNA-seq.  

Science.gov (United States)

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

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

Science.gov (United States)

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

Pseudomonas aeruginosa PAO1 bacterial artificial chromosomes: strategies for mapping, screening, and sequencing 100 kb loci of the 5.9 Mb genome.  

Science.gov (United States)

Pseudomonas aeruginosa is an opportunistic bacterial pathogen frequently found in nosocomial infections and is a major cause of morbidity and mortality in patients with cystic fibrosis. To facilitate molecular studies of this organism, we have generated a bacterial artificial chromosome (BAC) library. Genomic DNA was isolated from the prototype strain PAO1, partially digested with HindIII, size selected after pulsed-field gel electrophoresis, and used to construct a BAC library using the pBeloBAC11 vector. DNAs from approximately 850 clones, representing more than 9.5-fold physical coverage of the 5.9-Mb PAO1 genome, were analyzed after SpeI and HindIII digestions and agarose gel electrophoresis. The BAC library had clones with insert fragments ranging from 20 to more than 290 kb. A subset of 264 BACs having inserts > 80 kb, representing > 4 genome equivalents, were rearrayed into 96-well plates, and a clone pooling and PCR screening strategy was developed. The PCR library screening enabled the identification and recovery of BACs containing genes implicated in cell division and in cell wall biosynthesis, as well as a series of known genes mapping to different regions of the PAO1 chromosome. A physical and genetic map was constructed for the 98-kb pMOC5 BAC clone, which spans the entire fts-mur locus. Chromosome walking from each end of the pMOC5 clone placed it within a contig spanning 243 kb. The BAC library and screening resources now allow a PCR-based screening of a P. aeruginosa genomic library for any gene of interest. The restriction fragment analysis of overlapping clones indicated that BAC clones stably maintain and propagate Pseudomonas DNA, providing evidence that the PAO1 BAC library is an appropriate reagent for genome sequencing.

Earlier studies have shown that the stigma is prevalent even among psychiatric professionals and students of medicine and psychology. However, past studies on this issue often used questionnaires with a limited validity. Also questionnaires do not necessarily allow a neutral assessment of the underlying concepts of the student. Methods: In this study 133 students were asked to create mind maps on psychiatry. Results: In a systematic evaluation (based on a consensus of psychiatric concepts of 1353 concepts we found non-specific associations (N = 431 and five main categories: (i illness scirpts (n = 487; (ii therapeutic concepts (n = 241, (iii and (iv stigma and forensic psychiatry (81 mentions each; and (v psychopathology (n = 32. Stigma-associated negative concepts were more prevalent than positive connotations. Conclusions: Overall, it was shown that mind maps can be used with ease and quantified according to constructivist learning theory to explore disease concepts without the need for predefined or poorly validated questionnaires.[german] Zielsetzung: Trotz vieler Bemühungen, u. a. von Selbsthilfegruppen, der Fachgesellschaft und der Gesundheitspolitik gibt es in der Allgemeinbevölkerung immer noch eine Stigmatisierung der Psychiatrie als Fachgebiet. Frühere Untersuchungen zeigten, dass auch in der Psychiatrie tätige Menschen und Studierende der Medizin und Psychologie stigmatisierenden Äußerungen zustimmen. Zur genaueren Betrachtung wurden in der Vergangenheit jedoch meist Fragebögen verwendet, die eine begrenzte Validität haben und nicht zwangsläufig eine neutrale Beurteilung der zugrundeliegenden Konzepte der Studierenden erlauben.Methodik: In der vorliegenden Studie wurden 133 Studierende gebeten, Mind-Maps zum Thema Psychiatrie zu erstellen. Ergebnisse: In der systematischen Auswertung (auf der Basis vorher im Konsens bestimmter Konzepte von 1353 Begriffen ergaben sich neben unspezifischen Assoziationen (n=431 fünf Oberkategorien: 1. Krankheitsbilder (n=487; 2. Therapieformen (n=241; 3. und 4. Stigma-assoziierte Themen bzw. Eigen- und Fremdgefährdung (jeweils 81 Nennungen und 5. Psychopathologie (n=32. Negativ belegte Stigma-Themen waren wesentlich häufiger als positive Einstellungen zum Thema Stigma und betrafen meist Zwangsmaßnahmen. Schlussfolgerung: Insgesamt zeigte sich, dass Mind-Maps einfach eingesetzt und ausgewertet werden können, um Krankheitskonzepte und assoziierte Begriffe zu einem Fachgebiet im Sinne der konstruktivistischen Lerntheorie zu explorieren, ohne vordefinierte Fragebögen zu verwenden.

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

Directory of Open Access Journals (Sweden)

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

Evolutionary Fuzzy Cognitive Maps: A Hybrid System for Crisis Management and Political Decision Making  

Digital Repository Infrastructure Vision for European Research (DRIVER)

This paper proposes an extension of Certainty Neuron Fuzzy Cognitive Maps (CNFCMs) used in crisis management and decision-making, aiming at increasing their reliability. The objective of the Genetically Evolved Certainty Neuron Fuzzy Cognitive Map (GECNFCM) as it is introduced here is to overcome the main weakness of CNFCMs, which lies with the recalculation of the weights corresponding to each concept every time a new strategy is adopted. The problem is overcome through the introduction o...

Value adding management: A concept and a case  

DEFF Research Database (Denmark)

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

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

Energy Technology Data Exchange (ETDEWEB)

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

Auditory-Motor Mapping Training as an Intervention to Facilitate Speech Output in Non-Verbal Children with Autism: A Proof of Concept Study  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Although up to 25% of children with autism are non-verbal, there are very few interventions that can reliably produce significant improvements in speech output. Recently, a novel intervention called Auditory-Motor Mapping Training (AMMT) has been developed, which aims to promote speech production directly by training the association between sounds and articulatory actions using intonation and bimanual motor activities. AMMT capitalizes on the inherent musical strengths of children with autism...

Some Combined Relations between Contractive Mappings, Kannan Mappings, Reasonable Expansive Mappings, and -Stability  

Directory of Open Access Journals (Sweden)

Full Text Available In recent literature concerning fixed point theory for self-mappings in metric spaces , there are some new concepts which can be mutually related so that the inherent properties of each one might be combined for such self-mappings. Self-mappings can be referred to, for instance, as Kannan-mappings, reasonable expansive mappings, and Picard -stable mappings. Some relations between such concepts subject either to sufficient, necessary, or necessary and sufficient conditions are obtained so that in certain self-mappings can exhibit combined properties being inherent to each of its various characterizations.

Concepts and strategies on how to train and motivate teachers to implement a kindergarten-based, family-involved intervention to prevent obesity in early childhood. The ToyBox-study.  

Science.gov (United States)

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

Characteristics of Strategies in Product/Service-System Development  

DEFF Research Database (Denmark)

The underlying principle in Product/Service-Systems (PSS) strategy is to shift from business based on the value of the transfer of product ownership and responsibility, to business based on the value of utility of the product and services. This paper identifies characteristics of various strategies that may be applied in PSS development. PSS concepts created in projects by third year Design & Innovation students at the Technical University of Denmark (DTU) working with product-life oriented design approaches were reviewed, and the strategies developed were analysed. This identification and mapping of PSS strategy types gives us the opportunity to develop methods and approaches to PSS development, more tailored to specific business strategies.

Privacy Design Strategies  

Digital Repository Infrastructure Vision for European Research (DRIVER)

In this paper we define the notion of a privacy design strategy. These strategies help IT architects to support privacy by design early in the software development life cycle, during concept development and analysis. Using current data protection legislation as point of departure we derive the following eight privacy design strategies: minimise, hide, separate, aggregate, inform, control, enforce, and demonstrate. The strategies also provide a useful classification of privac...

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

International Nuclear Information System (INIS)

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