  1. The Structure and Dynamics of Co-Citation Clusters: A Multiple-Perspective Co-Citation Analysis

    CERN Document Server

    Chen, Chaomei; Hou, Jianhua

    2010-01-01

    A multiple-perspective co-citation analysis method is introduced for characterizing and interpreting the structure and dynamics of co-citation clusters. The method facilitates analytic and sense making tasks by integrating network visualization, spectral clustering, automatic cluster labeling, and text summarization. Co-citation networks are decomposed into co-citation clusters. The interpretation of these clusters is augmented by automatic cluster labeling and summarization. The method focuses on the interrelations between a co-citation cluster's members and their citers. The generic method is applied to a three-part analysis of the field of Information Science as defined by 12 journals published between 1996 and 2008: 1) a comparative author co-citation analysis (ACA), 2) a progressive ACA of a time series of co-citation networks, and 3) a progressive document co-citation analysis (DCA). Results show that the multiple-perspective method increases the interpretability and accountability of both ACA and DCA n...

  3. Co-citation Network Analysis of Religious Texts

    Science.gov (United States)

    Murai, Hajime; Tokosumi, Akifumi

    This paper introduces a method of representing in a network the thoughts of individual authors of dogmatic texts numerically and objectively by means of co-citation analysis and a method of distinguishing between the thoughts of various authors by clustering and analysis of clustered elements, generated by the clustering process. Using these methods, this paper creates and analyzes the co-citation networks for five authoritative Christian theologians through history (Augustine, Thomas Aquinas, Jean Calvin, Karl Barth, John Paul II). These analyses were able to extract the core element of Christian thought (Jn 1:14, Ph 2:6, Ph 2:7, Ph 2:8, Ga 4:4), as well as distinctions between the individual theologians in terms of their sect (Catholic or Protestant) and era (thinking about the importance of God's creation and the necessity of spreading the Gospel). By supplementing conventional literary methods in areas such as philosophy and theology, with these numerical and objective methods, it should be possible to compare the characteristics of various doctrines. The ability to numerically and objectively represent the characteristics of various thoughts opens up the possibilities of utilizing new information technology, such as web ontology and the Artificial Intelligence, in order to process information about ideological thoughts in the future.

    Full Text Available The general aim of a bibliometric map is to provide an overview of the structure of the scientific literature in a certain domain or on a certain topic. In the context of science policy and research management, bibliometric maps can be used to support decision making by governments, funding agencies, and universities. The articles have words and references which are the bibliometric data for co-citation analysis and co-word analysis. We try to find that these two bibliometric approaches show any correlation? We applied these approaches to University of Tehran’ productions published between 1999 and 2008, retrieved from the Web of Science. The results reveals 14 co-citation clusters and 6 co-word clusters. The clusters vary considerably in size. Co-word clusters emerged co-citation clusters.

    2012-11-01

    With the prevalence of Internet and digital archives, the online e-journal database facilitates scholars to search literature in a research domain, or to cross-search an inter-disciplined field; the key literature can be efficiently traced out. This study intends to build a Web-based citation analysis system, which consists of four modules, they are: 1) literature search module; (2) statistics module; (3) articles analysis module; and (4) co-citation analysis module. The system focuses on PubMed Central dataset that has 170,000 records. In a research domain, a specific keyword searches in terms of authors, journals, and core issues. In addition, we use data mining techniques for co-citation analysis. The results assist researchers with in-depth understanding of the domain knowledge. Having an automated system for co-citation analysis, it helps to understand changes, trends, and knowledge structure of research domain. For the best of our knowledge, the proposed system differentiates from existing online electronic retrieval database analysis function. Perhaps, the proposed system is going to be a value-added database of healthcare domain, and hope to contribute the researchers.

  7. The intellectual core of enterprise information systems: a co-citation analysis

    2016-10-01

    Enterprise information systems (EISs) have evolved in the past 20 years, attracting the attention of international practitioners and scholars. Although literature reviews and analyses have been conducted to examine the multiple dimensions of EISs, no co-citation analysis has been conducted to examine the knowledge structures involved in EIS studies; thus, the current study fills this research gap. This study investigated the intellectual structures of EISs. All data source documents (1083 articles and 24,090 citations) were obtained from the Institute for Scientific Information Web of Knowledge database. A co-citation analysis was used to analyse EIS data. By using factor analysis, we identified eight critical factors: (a) factors affecting the implementation and success of information systems (ISs); (b) the successful implementation of enterprise resource planning (ERP); (c) IS evaluation and success, (d) system science studies; (e) factors influencing ERP success; (f) case research and theoretical models; (g) user acceptance of information technology; and (h) IS frameworks. Multidimensional scaling and cluster analysis were used to visually map the resultant EIS knowledge. It is difficult to implement an EIS in an enterprise and each organisation exhibits specific considerations. The current findings indicate that managers must focus on ameliorating inferior project performance levels, enabling a transition from 'vicious' to 'virtuous' projects. Successful EIS implementation yields substantial organisational advantages.

  10. Two Decades of Research on Strategic Alliances: Analysis of Citations, Co-citations and Themes Researched

    Directory of Open Access Journals (Sweden)

    Manuel Portugal Ferreira

    2014-12-01

    Full Text Available Research on strategic alliances has a long tradition in management studies. Strategic alliances have been investigated using multiple theoretical lenses from RBV to agency and transaction cost, and diverse contexts, from the semiconductor to airline industries. In this study we scrutinize the extant strategic alliance research in thirtyone top-ranked business/management journals, over a twenty-year period, from 1993 to 2012. In a sample of 866 articles we conducted citation and co-citation analyses employing social network techniques and factor analysis to identify research themes and make sense of the stock of accumulated knowledge and theoretical trends. We were able to identify some shifts in research over time, namely from a focus on performance and theoretical emphasis on transaction cost theory and governance concerns, moving to a learning and knowledge transfer approach, social networks and collaboration. This study provides the foundations over which future research may develop to fill conceptual and empirical gaps.

    2017-03-08

    Regional trade agreements are major international policy instruments that shape macro-economic and political systems. There is widespread debate as to whether and how these agreements pose risks to public health. Here we perform a comprehensive systematic review of quantitative studies of the health impact of trade and investment agreements. We identified studies from searches in PubMed, Web of Science, EMBASE, and Global Health Online. Research articles were eligible for inclusion if they were quantitative studies of the health impacts of trade and investment agreements or policy. We systematically reviewed study findings, evaluated quality using the Quality Assessment Tool from the Effective Public Health Practice Project, and performed network citation analysis to study disciplinary siloes. Seventeen quantitative studies met our inclusion criteria. There was consistent evidence that implementing trade agreements was associated with increased consumption of processed foods and sugar-sweetened beverages. Granting import licenses for patented drugs was associated with increased access to pharmaceuticals. Implementing trade agreements and associated policies was also correlated with higher cardiovascular disease incidence and higher Body Mass Index (BMI), whilst correlations with tobacco consumption, under-five mortality, maternal mortality, and life expectancy were inconclusive. Overall, the quality of studies is weak or moderately weak, and co-citation analysis revealed a relative isolation of public health from economics. We identified limitations in existing studies which preclude definitive conclusions of the health impacts of regional trade and investment agreements. Few address unobserved confounding, and many possible consequences and mechanisms linking trade and investment agreements to health remain poorly understood. Results from our co-citation analysis suggest scope for greater interdisciplinary collaboration. Notwithstanding these limitations, our

    Background It has been argued that science and society are in the midst of a far-reaching renegotiation of the social contract between science and society, with society becoming a far more active partner in the creation of knowledge. On the one hand, new forms of knowledge production are emerging, and on the other, both science and society are experiencing a rapid acceleration in new forms of knowledge utilization. Concomitantly since the Second World War, the science underpinning the knowledge utilization field has had exponential growth. Few in-depth examinations of this field exist, and no comprehensive analyses have used bibliometric methods. Methods Using bibliometric analysis, specifically first author co-citation analysis, our group undertook a domain analysis of the knowledge utilization field, tracing its historical development between 1945 and 2004. Our purposes were to map the historical development of knowledge utilization as a field, and to identify the changing intellectual structure of its scientific domains. We analyzed more than 5,000 articles using citation data drawn from the Web of Science®. Search terms were combinations of knowledge, research, evidence, guidelines, ideas, science, innovation, technology, information theory and use, utilization, and uptake. Results We provide an overview of the intellectual structure and how it changed over six decades. The field does not become large enough to represent with a co-citation map until the mid-1960s. Our findings demonstrate vigorous growth from the mid-1960s through 2004, as well as the emergence of specialized domains reflecting distinct collectives of intellectual activity and thought. Until the mid-1980s, the major domains were focused on innovation diffusion, technology transfer, and knowledge utilization.

    Full Text Available Cahit Arf (1910-1997, a famous Turkish scientist whose picture is depicted in one of the Turkish banknotes, is a well-known figure in mathematics with his discoveries named after him (e.g., Arf invariant, Arf rings, the Hasse-Arf theorem. Although Arf may not be considered as a prolific scientist in terms of number of papers (he authored a total of 23 papers, his influence on mathematics and related disciplines was profound. As he was active before, during, and after World War II, Arf′s contributions are not properly listed in citation indexes, and thus did not generate many citations even though several papers with "Arf" in their titles appeared in literature. This paper traces influence of Arf in scientific world using citation analysis techniques first. It reviews scientific impact of Arf by analyzing both; the papers authored by Arf and papers whose titles or keywords containing various combinations of "Arf invariant," "Arf rings," and so on. The paper then goes on to study Arf′s contributions using social network analysis (SNA and author co-citation analysis (ACA techniques. CiteSpace and pennant diagrams are used to explore scientific impact of Arf by mapping his cited references derived from Thomson Reuters′ Web of Science (WoS database. The direct and indirect influences of Arf′s highly cited paper on Arf invariant are assessed through ACA and single publication h index, respectively. The paper ends with a discussion of whether data analysis techniques used in this study can be useful to study scientific impact of researchers retrospectively.

    The aim of this study was to examine how service user involvement can contribute to the development of interpretative phenomenological analysis methodology and enhance research quality. Interpretative phenomenological analysis is a qualitative methodology used in nursing research internationally to understand human experiences that are essential to the participants. Service user involvement is requested in nursing research. We share experiences from 4 years of collaboration (2012-2015) on a mental health promotion project, which involved an advisory team. Five research advisors either with a diagnosis or related to a person with severe mental illness constituted the team. They collaborated with the research fellow throughout the entire research process and have co-authored this article. We examined the joint process of analysing the empirical data from interviews. Our analytical discussions were audiotaped, transcribed and subsequently interpreted following the guidelines for good qualitative analysis in interpretative phenomenological analysis studies. The advisory team became 'the researcher's helping hand'. Multiple perspectives influenced the qualitative analysis, which gave more insightful interpretations of nuances, complexity, richness or ambiguity in the interviewed participants' accounts. The outcome of the service user involvement was increased breadth and depth in findings. Service user involvement improved the research quality in a nursing research project on mental health promotion. The interpretative element of interpretative phenomenological analysis was enhanced by the emergence of multiple perspectives in the qualitative analysis of the empirical data. We argue that service user involvement and interpretative phenomenological analysis methodology can mutually reinforce each other and strengthen qualitative methodology. © 2016 The Authors.

  7. CoCiter: an efficient tool to infer gene function by assessing the significance of literature co-citation.

    Directory of Open Access Journals (Sweden)

    Nan Qiao

    Full Text Available A routine approach to inferring functions for a gene set is by using function enrichment analysis based on GO, KEGG or other curated terms and pathways. However, such analysis requires the existence of overlapping genes between the query gene set and those annotated by GO/KEGG. Furthermore, GO/KEGG databases only maintain a very restricted vocabulary. Here, we have developed a tool called "CoCiter" based on literature co-citations to address the limitations in conventional function enrichment analysis. Co-citation analysis is widely used in ranking articles and predicting protein-protein interactions (PPIs. Our algorithm can further assess the co-citation significance of a gene set with any other user-defined gene sets, or with free terms. We show that compared with the traditional approaches, CoCiter is a more accurate and flexible function enrichment analysis method. CoCiter is freely available at www.picb.ac.cn/hanlab/cociter/.

    Ding, Ying; Frazho, Arthur; Caverlee, James

    2010-01-01

    Google's PageRank has created a new synergy to information retrieval for a better ranking of Web pages. It ranks documents depending on the topology of the graphs and the weights of the nodes. PageRank has significantly advanced the field of information retrieval and keeps Google ahead of competitors in the search engine market. It has been deployed in bibliometrics to evaluate research impact, yet few of these studies focus on the important impact of the damping factor (d) for ranking purposes. This paper studies how varied damping factors in the PageRank algorithm can provide additional insight into the ranking of authors in an author co-citation network. Furthermore, we propose weighted PageRank algorithms. We select 108 most highly cited authors in the information retrieval (IR) area from the 1970s to 2008 to form the author co-citation network. We calculate the ranks of these 108 authors based on PageRank with damping factor ranging from 0.05 to 0.95. In order to test the relationship between these diffe...

    This article mainly studies the consciousness of tax compliance through analogue experiment from the perspectives of “rational man” in economy, “sentimental man” and “social man” respectively. After taking comprehensive analysis of experimental results based on the perspectives of game theory, behavioral economics and sociology theory respectively, this article comes to the conclusions that the quality and efficiency of public goods provided by government would affect the taxpayers’ decision-making; the reference point and environment of decision-making would affect the taxpayer’s tax compliance; “the contagion effect” of tax compliance or tax noncompliance would be generated, and the impact would gradually diffuse the taxpayer groups. At the end, the relevant policy recommendations based on conclusions are made.%本文从经济学“理性人”、“感性人”和“社会人”三个角度出发,采用模拟实验的方法对个人纳税遵从意识问题进行了研究,在对实验数据分别以博弈论、行为经济学理论和社会学理论为基础做出综合分析后,得出以下结论:政府运用税款所提供的公共物品的质量和效果影响着纳税人的决策;纳税时的决策参考点和决策环境会影响纳税人的纳税遵从度;无论是纳税遵从行为还是纳税不遵从行为,都会产生“传染效应”,进而影响整个纳税人群体的纳税遵从度。最后本文结合这些结论给出了相关政策建议。

    The authors of this commentary discuss the recently completed review of the current Medical College Admission Test (MCAT), which has been used since 1991, and describe the blueprint for the new test that will be introduced in 2015. The design of the MCAT exam reflects changes in medical education, medical science, health care delivery, and the needs of the populations served by graduates of U.S. and Canadian medical schools. The authors describe how balancing the ambitious goals for the new exam and the varying priorities of the testing program's many stakeholders made blueprint design complex. They discuss the tensions and trade-offs that characterized the design process as well as the deliberations and data that shaped the blueprint.The blueprint for the MCAT exam balances the assessment of a broad range of competencies in the natural, social, and behavioral sciences and critical analysis and reasoning skills that are essential to entering students' success in medical school. The exam will include four sections: Biological and Biochemical Foundations of Living Systems; Chemical and Physical Foundations of Biological Systems; Psychological, Social, and Biological Foundations of Behavior; and Critical Analysis and Reasoning Skills.The authors also offer recommendations for admission committees, advising them to review applicants' test scores, course work, and other academic, personal, and experiential credentials as part of a holistic admission process and in relation to their institutions' educational, scientific, clinical, and service-oriented goals.

    Dissemination of battlespace information involves getting information to particular warfighters that is both useful and in a form that facilitates the tasks of those particular warfighters. There are two issues which motivate this problem of dissemination. The first issue deals with disseminating pertinent information to a particular warfighter. This can be thought of as information suppression. The second issue deals with facilitating the use of the information by tailoring the computer interface to the specific tasks of an individual warfighter. This can be thought of as interface complexity suppression. This paper presents a framework for suppressing information using an object-based knowledge representation methodology. This methodology has the ability to represent knowledge and information in multiple perspectives. Information can be suppressed by creating a perspective specific to an individual warfighter. In this way, only the information pertinent and useful to a warfighter is made available to that warfighter. Information is not removed, lost, or changed, but spread among multiple perspectives. Interface complexity is managed in a similar manner. Rather than have one generalized computer interface to access all information, the computer interface can be divided into interface elements. Interface elements can then be selected and arranged into a perspective-specific interface. This is done in a manner to facilitate completion of tasks contained in that perspective. A basic battlespace domain containing ground and air elements and associated warfighters is used to exercise the methodology.

    2016-05-01

    The concept of perspectives is important in discussions about the multidimensionality of sustainability problems and the need to consider many different aspects when dealing with them. This paper aims to facilitate discussions among both educators and researchers about didactical approaches to developing students' abilities to deal with the multidimensionality of sustainability challenges through the use of multiple perspectives. For this purpose, a theoretical framework was developed that describes perspectives in terms of a set of general characteristics, as well as a number of ways in which students can develop and reflect on perspectives. Development of the framework was supported by a qualitative content analysis of transcripts from interviews with undergraduate engineering students in Sweden.

  10. Structuring Climate Adaptation through Multiple Perspectives: Framework and Case Study on Flood Risk Management

    Directory of Open Access Journals (Sweden)

    Mohanasundar Radhakrishnan

    2017-02-01

    Full Text Available Adaptation to climate change is being addressed in many domains. This means that there are multiple perspectives on adaptation; often with differing visions resulting in disconnected responses and outcomes. Combining singular perspectives into coherent, combined perspectives that include multiple needs and visions can help to deepen the understanding of various aspects of adaptation and provide more effective responses. Such combinations of perspectives can help to increase the range and variety of adaptation measures available for implementation or avoid maladaptation compared with adaptations derived from a singular perspective. The objective of this paper is to present and demonstrate a framework for structuring the local adaptation responses using the inputs from multiple perspectives. The adaptation response framing has been done by: (i contextualizing climate change adaptation needs; (ii analyzing drivers of change; (iii characterizing measures of adaptation; and (iv establishing links between the measures with a particular emphasis on taking account of multiple perspectives. This framework was demonstrated with reference to the management of flood risks in a case study Can Tho, Vietnam. The results from the case study show that framing of adaptation responses from multiple perspectives can enhance the understanding of adaptation measures, thereby helping to bring about more flexible implementation practices.

  14. When counting cattle is not enough: multiple perspectives in agricultural and veterinary research

    Science.gov (United States)

    2011-01-01

    A traditional approach in agricultural and veterinary research is focussing on the biological perspective where large cattle-databases are used to analyse the dairy herd. This approach has yielded valuable insights. However, recent research indicates that this knowledge-base can be further increased by examining agricultural and veterinary challenges from other perspectives. In this paper we suggest three perspectives that may supplement the biological perspective in agricultural and veterinary research; the economic-, the managerial-, and the social perspective. We review recent studies applying or combining these perspectives and discuss how multiple perspectives may improve our understanding and ability to handle cattle-health challenges. PMID:21999487

  18. Multiple perspectives on shared decision-making and interprofessional collaboration in mental healthcare.

    Science.gov (United States)

    Chong, Wei Wen; Aslani, Parisa; Chen, Timothy F

    2013-05-01

    Shared decision-making is an essential element of patient-centered care in mental health. Since mental health services involve healthcare providers from different professions, a multiple perspective to shared decision-making may be valuable. The objective of this study was to explore the perceptions of different healthcare professionals on shared decision-making and current interprofessional collaboration in mental healthcare. Semi-structured interviews were conducted with 31 healthcare providers from a range of professions, which included medical practitioners (psychiatrists, general practitioners), pharmacists, nurses, occupational therapists, psychologists and social workers. Findings indicated that healthcare providers supported the notion of shared decision-making in mental health, but felt that it should be condition dependent. Medical practitioners advocated a more active participation from consumers in treatment decision-making; whereas other providers (e.g. pharmacists, occupational therapists) focused more toward acknowledging consumers' needs in decisions, perceiving themselves to be in an advisory role in supporting consumers' decision-making. Although healthcare providers acknowledged the importance of interprofessional collaboration, only a minority discussed it within the context of shared decision-making. In conclusion, healthcare providers appeared to have differing perceptions on the level of consumer involvement in shared decision-making. Interprofessional roles to facilitate shared decision-making in mental health need to be acknowledged, understood and strengthened, before an interprofessional approach to shared decision-making in mental health can be effectively implemented.

The second perspective comes from discussions with scientists on the topic of E/PO. Evaluation data of scientists' involvement in a community college space science seminar series provides a third perspective. And the final perspective approaches the topic from the vantage point of research on scientist involvement in E/PO. From these multiple perspectives, there is evidence that that there exists ample passion for education and outreach in the scientific community. However, the path from passion to meaningful engagement of audiences and understandings of educational pedagogies continues to be difficult for a variety of reasons, such as: 1) a tendency to teach as one was taught rather than changing teaching practices based on research on how people learn, 2) a lack of time to collaborate and partner with appropriate educational professionals or institutions, 3) a lack of awareness (or a lack of time to develop an awareness) of an audience need or audience baseline understandings, and 4) a belief that science is supra-cultural and can be shared outside of a cultural context. It is suggested that the most effective way for scientists to engage in E/PO is to develop professional relationships with educators in the field of education and outreach for which the scientist is passionate (such as a middle school teacher if the passion lies in sharing science with middle school students.) E/PO professionals can also support and guide the passion with an understanding of best practices in E/PO. Spending time within the culture of the audience one wishes to work with can also be helpful in

    Full Text Available Abstract Background Cardio-metabolic diseases (CMDs are a growing public health problem, but data on incidence, trends, and costs in developing countries is scarce. Comprehensive and standardised surveillance for non-communicable diseases was recommended at the United Nations High-level meeting in 2011. Aims: To develop a model surveillance system for CMDs and risk factors that could be adopted for continued assessment of burdens from multiple perspectives in South-Asian countries. Methods Design: Hybrid model with two cross-sectional serial surveys three years apart to monitor trend, with a three-year prospective follow-up of the first cohort. Sites: Three urban settings (Chennai and New Delhi in India; Karachi in Pakistan, 4000 participants in each site stratified by gender and age. Sampling methodology: Multi-stage cluster random sampling; followed by within-household participant selection through a combination of Health Information National Trends Study (HINTS and Kish methods. Culturally-appropriate and methodologically-relevant data collection instruments were developed to gather information on CMDs and their risk factors; quality of life, health-care utilisation and costs, along with objective measures of anthropometric, clinical and biochemical parameters. The cohort follow-up is designed as a pilot study to understand the feasibility of estimating incidence of risk factors, disease events, morbidity, and mortality. Results The overall participant response rate in the first cross-sectional survey was 94.1% (Chennai 92.4%, n = 4943; Delhi 95.7%, n = 4425; Karachi 94.3%, n = 4016. 51.8% of the participants were females, 61.6% 60 years. Discussion This surveillance model will generate data on prevalence and trends; help study the complex life-course patterns of CMDs, and provide a platform for developing and testing interventions and tools for prevention and control of CMDs in South-Asia. It will also help understanding the

    3D-Video systems allow a user to perceive depth in the viewed scene and to display the scene from arbitrary viewpoints interactively and on-demand. This paper presents a prototype implementation of a 3D-video streaming system using an IP network. The architecture of our streaming system is layered, where each information layer conveys a single coded video signal or coded scene-description data. We demonstrate the benefits of a layered architecture with two examples: (a) stereoscopic video streaming, (b) monoscopic video streaming with remote multiple-perspective rendering. Our implementation experiments confirm that prototyping 3D-video streaming systems is possible with today's software and hardware. Furthermore, our current operational prototype demonstrates that highly heterogeneous clients can coexist in the system, ranging from auto-stereoscopic 3D displays to resource-constrained mobile devices.

  5. van Eijck and Roth's utilitarian science education: why the recalibration of science and traditional ecological knowledge invokes multiple perspectives to protect science education from being exclusive

    Mueller, Michael P.; Tippins, Deborah J.

    2010-12-01

    This article is a philosophical analysis of van Eijck and Roth's (2007) claim that science and traditional ecological knowledge (TEK) should be recalibrated because they are incommensurate, particular to the local contexts in which they are practical. In this view, science maintains an incommensurate status as if it is a "fundamental" basis for the relative comparison of other cultural knowledges, which reduces traditional knowledge to a status of in relation to the prioritized (higher)-status of natural sciences. van Eijck and Roth reject epistemological Truth as a way of thinking about sciences in science education. Rather they adopt a utilitarian perspective of cultural-historical activity theory to demonstrate when traditional knowledge is considered science and when it is not considered science, for the purposes of evaluating what should be included in U.S. science education curricula. There are several challenges for evaluating what should be included in science education when traditional knowledges and sciences are considered in light of a utilitarian analysis. Science as diverse, either practically local or theoretically abstract, is highly uncertain, which provides opportunities for multiple perspectives to enlarge and protect the natural sciences from exclusivity. In this response to van Eijck and Roth, we make the case for considering dialectical relationships between science and TEK in order to ensure cultural diversity in science education, as a paradigm. We also emphasize the need to (re)dissolve the hierarchies and dualisms that may emerge when science is elevated in status in comparison with other knowledges. We conclude with a modification to van Eijck and Roth's perspective by recommending a guiding principle of cultural diversity in science education as a way to make curriculum choices. We envision this principle can be applied when evaluating science curricula worldwide.

The study, of a qualitative nature, used document analysis, interviews and observations. The results show, on the one hand, the historical struggle of a peripheral community for access to education and, on the other, the difficulties of different orders that are interposed between the school achievement and the quality of education offered. The pseudo-autonomy in the planning and development processes of pedagogical practice, the precariousness of the school, the teachers’ working conditions and the conflicting relationships between students and teachers are among the problems highlighted.

  9. Comparison of risk assessment methods: multiple perspectives of flood and avalanche hazards in North East France

    Giacona, Florie; Eleuterio, Julian

    2010-05-01

    Mountainous areas are exposed to several natural hazards such as snow avalanches, debris flows or floods. Such processes may be more frequent and intense in high mountains but they occur in medium-high mountains as well causing loss of life and materials. Thus, the Vosges range, a medium-high mountain located in the north-east of France, is concerned by two kind of natural hazards namely avalanches and floods. While the avalanches constitute the most murderous natural risk in Alsace, its management is paradoxically not a priority. Because it causes more material damages and affects larger places with multiple and complex consequences, the flood risk is more worrying for the administrators. They didn't have the same approach toward these two kinds of risk. So, two different approaches used to assess risk and two study cases are presented: flood risk in the river Bruche (located in the north of the Vosges range, Alsace) and avalanche risk in the Vosges range. The first one is mainly focused on economic aspects of risk. Flood risk analyses are discussed from a hydro-economical perspective. The second one focuses the analysis on human, material and environmental vulnerabilities. Avalanche risk analysis is discussed from a geo-historical point of view. About 300 avalanche events have been reported since the end of the 18th century. The two approaches that we describe illustrate the complementarity of human and physical science to improve the understanding and assessment of hazardous processes in medium-high mountain range. On the one hand, the geo-historical method developed for the avalanche risk could be extended to the flood hazard. Indeed, contrary to high mountains, no service is in charge of the systematic inventory of floods and avalanches in the Vosges mountains. The geo-historical approach could address this lack of data. On the other hand, the methods of damages assessment and vulnerability characterization could be a good tool for the human science.

    2012-07-01

    Full Text Available Both students and teachers need different competences for scientific reasoning. Apart from the required content knowledge and the ability of using it adequately, both groups need elaborated knowledge of strategies for decision-making and argumentation. These competences concerning decision-making are highly dependent on how frequently students are given the chance to argue in science classes. This article pools the results of three different research projects in chemistry education which focus on these three aspects: Students’ competences, the classroom situation with regard to communication and reasoning and teachers’ competences. Students’ skills needed for discussing chemistry content and for decision-making in scientific contexts are analyzed first. Following this, the opportunities for improving these skills during science lessons are researched and related to results from a study of teachers’ pedagogical content knowledge (PCK in this domain. The analysis of students’ and teachers’ communication skills is conducted in two different ways which are paper-pencil tests and video analysis. Paper-pencil tests are used to assess students’ performance in reasoning. The test items deal with chemistry-specific situations, including opportunities for decision-making, which are typical of socio-scientific issues (study 1. The study shows that students’ decision-making skills are poor when the topics deal with scientific contexts, but that students perform better when dealing with everyday-life contexts. One reason might be the lack of reasoning in chemistry lessons, as shown by a video study conducted in chemistry classes. Students’ and teachers’ in-class behavior and communication patterns are analyzed with regard to students’ and teachers’ contributions (study 2. The amount and the quality of students’ and teachers’ statements as well as the interactions, especially teachers’ reactions to students’ statements are

    Full Text Available Abstract Background Available evidence suggests that improvements in genetics education are needed to prepare primary care providers for the impact of ongoing rapid advances in genomics. Postgraduate (physician training and master (midwifery training programmes in primary care and public health are failing to meet these perceived educational needs. The aim of this study was to explore the role of genetics in primary care (i.e. family medicine and midwifery care and the need for education in this area as perceived by primary care providers, patient advocacy groups and clinical genetics professionals. Methods Forty-four participants took part in three types of focus groups: mono-disciplinary groups of general practitioners and midwives, respectively and multidisciplinary groups composed of a diverse set of experts. The focus group sessions were audio-taped, transcribed verbatim and analysed using content analysis. Recurrent themes were identified. Results Four themes emerged regarding the educational needs and the role of genetics in primary care: (1 genetics knowledge, (2 family history, (3 ethical dilemmas and psychosocial effects in relation to genetics and (4 insight into the organisation and role of clinical genetics services. These themes reflect a shift in the role of genetics in primary care with implications for education. Although all focus group participants acknowledged the importance of genetics education, general practitioners felt this need more urgently than midwives and more strongly emphasized their perceived knowledge deficiencies. Conclusion The responsibilities of primary care providers with regard to genetics require further study. The results of this study will help to develop effective genetics education strategies to improve primary care providers' competencies in this area. More research into the educational priorities in genetics is needed to design courses that are suitable for postgraduate and master programmes for

    2017-10-01

    The valuation of urban water management practices and associated nature-based solutions (NBS) is highly contested, and is becoming increasingly important to cities seeking to increase their resilience to climate change whilst at the same time facing budgetary pressures. Different conceptions of 'values' exist, each being accompanied by a set of potential measures ranging from calculative practices (closely linked to established market valuation techniques) - through to holistic assessments that seek to address wider concerns of sustainability. Each has the potential to offer important insights that often go well beyond questions of balancing the costs and benefits of the schemes concerned. However, the need to address - and go beyond - economic considerations presents policy-makers, practitioners and researchers with difficult methodological, ethical and practical challenges, especially when considered without the benefit of a broader theoretical framework or in the absence of well-established tools (as might apply within more traditional infrastructural planning contexts, such as the analysis of transport interventions). Drawing on empirical studies undertaken in Sheffield over a period of 10 years, and delivered in partnership with several other European cities and regions, we compare and examine different attempts to evaluate the benefits of urban greening options and future development scenarios. Comparing these different approaches to the valuation of nature-based solutions alongside other, more conventional forms of infrastructure - and indeed integrating both 'green and grey' interventions within a broader framework of infrastructures - throws up some surprising results and conclusions, as well as providing important sign-posts for future research in this rapidly emerging field.

    This paper reports on school transition for 15 mathematically gifted Year 6 and Year 8 students. The data are extracted from a longitudinal qualitative study that examined student and parent perspectives, and programme provision for mathematically gifted and talented students before and after a change of schools. The students moved from primary school to intermediate school (Years 7 and 8) or to a Years 7-13 secondary school. Another group of students moved from intermediate school to secondary school. The students', their parents', and their teachers' perceptions of the transitions are described. The students report an expectation for a greater level of mathematical challenge in their new school and to continue to work with like-minded peers. Some schools practise `fresh start' indicating mistrust between sectors. Successful transitions occur when there is a strong inter-relationship with students, parents, and teachers.

    2015-01-01

    To date, there has been a lack of consensus among researchers, practitioners, and laypersons about the definition of cyberbullying. Researchers have typically applied the key characteristics of intent to harm, power imbalance, and repetition from the definition of traditional bullying to cyberbullying, but how these characteristics transfer from the real world to a technology-mediated environment remains ambiguous. Moreover, very few studies have specifically investigated how cyberbullying is defined from the perspective of bullies, victims and bystanders. To this end, this article will propose a three-part definition of cyberbullying, which incorporates the perspective of bullies, victims and bystanders.

    A bibliometric analysis based on the Science Citation Index Expanded (SCI-Expanded) from the Web of Science was carried out to provide insights into research activities and tendencies of the global risk of engineering nanomaterials (ENMs) from 1999 to 2012. The number of publications per year has increased steadily since approximately 2006. The USA produced 41.9% of all pertinent articles followed by China with 14.8% and UK with 9.1%. Environmental Science & Technology, Toxicology, and Journal of Nanoparticle Research were the three most common journals in this field. A synthesized analysis by co-citation and words from author keywords provided the clues to discover the current research emphases. The mainstream research related to risk of ENMs was toxicological effects and ecological risk. Toxicity effect strongly promoted the development of related research in the past 14 years. Research on environmental behavior and ecological risk of ENMs is the fast growing field.

The key words that showed high frequency in these publications were included for analyzing the research fronts and development trends for sciatic nerve injury repair and protection. Through word frequency trend analysis, studies on bone marrow mesen-chymal stem cells, adipose-derived stem cells, and skeletal muscle-derived multipotent stem cells combined with tissue-engineered scaffold material will become the forefronts in the ifeld of sci-atic nerve injury repair and protection in the near future.

    作为企业家重要的个体异质性特征,企业家社会资本对于转型经济时期的中国企业多元化战略决策具有重要的影响,而现有研究往往忽略了这一点.基于现有社会资本研究成果,从社会网络和动员能力两个维度界定了企业家社会资本.在此基础上,从网络嵌入的信息、知识和通用资源等三个方面分析了企业家社会资本与多元化战略的关系.研究发现,企业家的社会网络规模越大、动员能力越强,则企业越倾向于提高多元化程度、选择不相关多元化和通过并购来实施多元化战略.%As an important personal unique character of entrepreneur, under the condition of economy transition of China, entrepreneur social capital (ESC) plays a significant role in diversification strategy decision in Chinese finns, while which is ignored in current research. This paper defines ESC with two dimensions of social network and access capability on the base of current literatures on social capital. Based on the frame, we divide the resources embedded in social network to information, knowledge and general resource and analyze the relationship between ESC and diversification strategy. The results show that firms with larger entrepreneur social network and stronger access capability will be more likely to increase their diversity level, choose unrelated diversification and M&A model.

    Past research supported the importance of parental autonomy support, involvement, and structure for student outcomes. The goal of this study was to test the contribution of these behaviors from mothers and fathers in predicting adolescents' adjustment in school using a multi-informant approach. A sample of 522 adolescents (233 boys, 389 girls), their mothers (n = 535), and fathers (n = 296) participated in the study. Results revealed that parents' self-evaluations explained additional variance in children's school adjustment, over and beyond the contribution of children's evaluation of their parents. Maternal reports on their positive behaviors (autonomy support, involvement, and structure) predicted their child's academic and emotional adjustment while their reported control predicted lower levels of these. Fathers' self-reported positive behaviors predicted academic adjustment while their control predicted lower academic and personal-emotional adjustment. These findings support the importance of multiple assessments of parental behaviors for improving the prediction of adjustment in school.

  14. 效用、基本善與能力發展―論「平等」的多元視野及其教育蘊義 Utility, Primary Goods, and the Capabilities Approach: Multiple Perspectives on “Equality” and Their Educational Implications

    2012-06-01

    Full Text Available 本文之目的係在Sen〈什麼樣的平等?〉一文的基礎上,藉由效益論、正義論與能力取向理論等相關文獻之分析,深入探究「效益平等」、「總體效用平等」、「Rawls的基本善平等」,以及「基本能力平等」等四種不同觀點之內涵及其侷限性。相較於能力取向理論在福利經濟學與倫理學領域已累積的大量文獻,能力取向理論之教育應用研究卻仍極為有限。因此,本文最後嘗試提出「平等」的多元思維取向,期待能夠為未來教育公平議題研究提供更妥適的倫理學基礎。 This essay, based on the foundations laid out by Amartya Sen in his article “Equality of what?” as well as other related literature and studies on utilitarianism, theory of justice, and the capabilities approach, delved into the contents and limitations of four different “equality” viewpoints which encompassed “utilitarian equality,” “total utility equality,” the “Rawlsian equality of primary goods,” and the “basic capability equality.” A large amount of research had been previously conducted on the application of the capabilities approach to welfare economics and ethics, but research on the educational applications of the capabilities approach remained comparatively sparse. To address this problem, this essay proposes in its concluding section multiple perspectives on “equality” and attempted to provide an ethical foundation that would better suite the discussions of educational equality in the future.

    Full Text Available The study investigated teacher knowledge of error analysis in differential calculus. Two teachers were the sample of the study: one a subject specialist and the other a mathematics education specialist. Questionnaires and interviews were used for data collection. The findings of the study reflect that the teachers’ knowledge of error analysis was characterised by the following assertions, which are backed up with some evidence: (1 teachers identified the errors correctly, (2 the generalised error identification resulted in opaque analysis, (3 some of the identified errors were not interpreted from multiple perspectives, (4 teachers’ evaluation of errors was either local or global and (5 in remedying errors accuracy and efficiency were emphasised more than conceptual understanding. The implications of the findings of the study for teaching include engaging in error analysis continuously as this is one way of improving knowledge for teaching.

  16. The health effects of the global financial crisis: can we reconcile the differing views? A network analysis of literature across disciplines.

    Science.gov (United States)

    Stuckler, David; Reeves, Aaron; Karanikolos, Marina; McKee, Martin

    2015-01-01

    Why are researchers studying the health effects of economic change reaching markedly varying conclusions? To understand these differences, we first systematically searched Web of Science for the literature on recessions and health yielding 461 articles and 14,401 cited documents. We then undertook a network analysis of co-citation pattern by disciplines, journals and backgrounds of the authors, followed by a chronological review of the literature, to trace the evolution of ideas. We then examined the extent to which earlier literature predicted what has happened in the 2007-2012 crisis. Our analysis finds the literature is dominated by disciplinary silos, with economics studies predominantly citing each other and relative isolation of psychiatry and substance abuse journals. Different philosophical approaches to assessing causality appear to contribute to varying interpretations, a tendency that is unlikely to be resolved without a shift in research norms. We conclude by calling for more inter-disciplinary research that combines empirical findings with a search for plausible mechanisms. This approach would evaluate not only the effects of economic shocks but also the mechanisms that offer protection against them.

    In this paper, the results of a bibliometric and visual analysis of geo-ontology research articles collected from the Web of Science (WOS) database between 1999 and 2014 are presented. The numbers of national institutions and published papers are visualized and a global research heat map is drawn, illustrating an overview of global geo-ontology research. In addition, we present a chord diagram of countries and perform a visual cluster analysis of a knowledge co-citation network of references, disclosing potential academic communities and identifying key points, main research areas, and future research trends. The International Journal of Geographical Information Science, Progress in Human Geography, and Computers & Geosciences are the most active journals. The USA makes the largest contributions to geo-ontology research by virtue of its highest numbers of independent and collaborative papers, and its dominance was also confirmed in the country chord diagram. The majority of institutions are in the USA, Western Europe, and Eastern Asia. Wuhan University, University of Munster, and the Chinese Academy of Sciences are notable geo-ontology institutions. Keywords such as "Semantic Web," "GIS," and "space" have attracted a great deal of attention. "Semantic granularity in ontology-driven geographic information systems, "Ontologies in support of activities in geographical space" and "A translation approach to portable ontology specifications" have the highest cited centrality. Geographical space, computer-human interaction, and ontology cognition are the three main research areas of geo-ontology. The semantic mismatch between the producers and users of ontology data as well as error propagation in interdisciplinary and cross-linguistic data reuse needs to be solved. In addition, the development of geo-ontology modeling primitives based on OWL (Web Ontology Language)and finding methods to automatically rework data in Semantic Web are needed. Furthermore, the topological

    2013-04-23

    Teaching and learning strategies are needed to support learner-centered curricula, and prepare nurses who are capable of working in today's challenging health care environments. Although the traditional lecture is still widely used in nursing education, innovative approaches are needed to encourage discussion, debate, and critical reflection, activities that support lifelong learning. Arts-based learning [ABL] is a creative strategy with the potential to engage learners, foster understanding of multiple perspectives, and simultaneously connect cognitive and affective domains of learning. Walker and Avant's method of concept analysis is applied to examine the uses of ABL in the literature, define the attributes, distinguish the antecedents and consequences, identify model and other cases, and determine empirical referents of this concept. This analysis is presented to facilitate the conceptual understanding of ABL for use in research and nursing education.

    Full Text Available The purpose of the present study was to analyze the interdisciplinary relations of “Library Science and Information Science”. For this purpose the subject categories of citing and cited journals of these fields were investigated in JCR database during the period of 1987-1997 and 2003-2013, and through the comparsion of obtained results the impact of information technology on the development of “LIS” interdisciplinarity was investigated. Methedology of the research was co-citation analysis of journals in scientometrics studies. Also the research was performed using the conventional techniques of scientometrics including Bradford law, Ward hierarchical clustering approach in statistical software SPSS, and the new measure including Proximity index. Research community includes citing and cited journals of 56 “LIS” journals during 1987-1997 and 83 journals during 2003-2013 in Journals Ctiation Report (JCR database. The results showed that “LIS” has been influenced by other subject categories more than affecting them. For example, the number of journals which “LIS” cited from 1758 (in the first period has increased to 5303 (in the second period. Co-occurrence matrix of core citing and cited subject categories was analyzed, and three main clusters in the first period and seven clusters in the second period were drawn. In general, the amount and quality of co-occurrence of subject categories in clusters showed that the domain and variety of affecting and affected subject categories were expanded in the second period. Structural similarity of clusters for affecting and affected subject categories calculated. Results showed that structural similarity of clusters in the second period was %10 higher than in the first period. Also, the Structural similarity of affecting clusters of “LIS” was more than affected clusters. Assessment of difference between subject categories groups by ANOVA and Tukey Post hoc tests showed that there were

    Co-occurrence matrices, such as co-citation, co-word, and co-link matrices, have been used widely in the information sciences. However, confusion and controversy have hindered the proper statistical analysis of this data. The underlying problem, in our opinion, involved understanding the nature of various types of matrices. This paper discusses the difference between a symmetrical co-citation matrix and an asymmetrical citation matrix as well as the appropriate statistical techniques that can be applied to each of these matrices, respectively. Similarity measures (like the Pearson correlation coefficient or the cosine) should not be applied to the symmetrical co-citation matrix, but can be applied to the asymmetrical citation matrix to derive the proximity matrix. The argument is illustrated with examples. The study then extends the application of co-occurrence matrices to the Web environment where the nature of the available data and thus data collection methods are different from those of traditional databa...

    The development of Link Analysis is affected by theories of Citation Analysis. The basic hypothesis and application of Link Analysis is similar to that of Citation Analysis. For example, Web Impact Factor originated from Journal Impact Factor, Co-link Analysis from Co-citation Analysis. On the other hand, the dynamics of the Web endows Link Analysis with some unique characteristics, which may inspire the research on Citation Analysis to some degree. This paper proposed the "Paperank" algorithm, which was originated from Google's PageRank algorithm. To demonstrate the Paperank, a set of papers was chosen from SCIE (Science Citation Index Expanded) with the topic of Webometrics. The advantages of the Paperank algorithm were revealed after the comparison between it and Times Cited. Furthermore, the paper introduced the potential application of Paperank: in the rank of search results of journal articles databases.%链接分析的发展受引文分析理论的影响,在基本假设前提与应用等方面,链接分析都与引文分析相似,例如,网络影响因子来源于期刊影响因子,共链分析来源于共被引分析.另一方面,网络的动态性赋予了链接分析一些特性,这些特性对于引文分析研究有启示作用.本文在简要介绍引文分析与链接分析的相关理论之后,基于链接分析中的PageRank算法提出了Paperank算法,用于引文分析.在对算法的论证过程中,笔者选取了SCEI中的"Webometrics"相关论文为样本,通过比较这些论文的Paperank值与被引次数,凸显Paperank算法的优点.最后,本文提出了Paperank算法的应用前景--学术期刊论文数据库的检索结果排序.

    The extraordinarily rapid advances made in mathematics since World War II have resulted in analysis becoming an enormous organism spread­ ing in all directions. Gone for good surely are the days of the great French "courses of analysis" which embodied the whole of the "ana­ lytical" knowledge of the times in three volumes-as the classical work of Camille Jordan. Perhaps that is why present-day textbooks of anal­ ysis are disproportionately modest relative to the present state of the art. More: they have "retreated" to the state before Jordan and Goursat. In recent years the scene has been changing rapidly: Jean Dieudon­ ne is offering us his monumentel Elements d'Analyse (10 volumes) written in the spirit of the great French Course d'Analyse. To the best of my knowledge, the present book is the only one of its size: starting from scratch-from rational numbers, to be precise-it goes on to the theory of distributions, direct integrals, analysis on com­ plex manifolds, Kahler manifolds, the theory of sheave...

    Full Text Available Drought caused the most widespread damage in China, making up over 50 % of the total affected area nationwide in recent decades. In the paper, a Standardized Precipitation Index-based (SPI-based drought risk study is conducted using historical rainfall data of 19 weather stations in Shandong province, China. Kernel density based method is adopted to carry out the risk analysis. Comparison between the bivariate Gaussian kernel density estimation (GKDE and diffusion kernel density estimation (DKDE are carried out to analyze the effect of drought intensity and drought duration. The results show that DKDE is relatively more accurate without boundary-leakage. Combined with the GIS technique, the drought risk is presented which reveals the spatial and temporal variation of agricultural droughts for corn in Shandong. The estimation provides a different way to study the occurrence frequency and severity of drought risk from multiple perspectives.

    Purpose: This paper introduces an approach to technology evolution analysis using patent information based on Subject-Action-Object(SAO) structures.Design/methodology/approach: First, SAO structures were extracted from patent documents and were cleaned. Second, several dimension-reduction techniques were used to generate technology topics. Then, the hierarchical relationships between technology topics were calculated based on patent clustering. Finally, technology evolution maps were drawn by adding a timeline.Findings: This approach can reveal technology evolution processes from multiple perspectives than other approaches.Research limitations: The semantic annotation of an SAO type is not very accurate and the semantic types of technology topics need to be enriched.Practical implications: The approach can be applied to draw technology evolution maps using different types of technology topics such as problem or solution.Originality/value: This approach offers an analytical dimension and more details than existing techniques, and it helps identify fundamental and emerging technologies more accurately and comprehensively.

    Ar Rika fault zone constitutes one of the two major parts of the NW-SE Najd fault system (NFS), which is one of the most prominent structural features located in the east of the center of the Arabian Shield, Saudi Arabia. By using Enhancement Thematic Mapper data (ETM+) and Principle Component Analysis (PCA), surface geological characteristics, distribution of rock types, and the different trends of linear features and faults are determined in the study area. First and second order magnetic gradients of the geomagnetic field at the North East of Wadi Ar Rika have been calculated in the frequency domain to map both surface and subsurface lineaments and faults. Lineaments as deduced from previous studies, suggest an extension of the NFS beneath the cover rocks in the study area. In the present study, integration of magnetic gradients and remote sensing analysis that resulted in different valuable derivative maps confirm the subsurface extension of some of the surface features. The 3D Euler deconvolution, the total gradient, and the tilt angle maps have been utilized to determine accurately the distribution of shear zones, the tectonic implications, and the internal structures of the terranes in the Ar Rika quadrangle in three dimensions.

    2008-03-01

    A half-day forum to address a wide range of issues related to translational neural engineering was conducted at the annual meeting of the Biomedical Engineering Society. Successful practitioners of translational neural engineering from academics, clinical medicine and industry were invited to share a diversity of perspectives and experiences on the translational process. The forum was targeted towards traditional academic researchers who may be interested in the expanded funding opportunities available for translational research that emphasizes product commercialization and clinical implementation. The seminar was funded by the NIH with support from the Rehabilitation Institute of Chicago. We report here a summary of the speaker viewpoints with particular focus on extracting successful strategies for engaging in or conducting translational neural engineering research. Daryl Kipke, PhD, (Department of Biomedical Engineering at the University of Michigan) and Molly Shoichet, PhD, (Department of Chemical Engineering at the University of Toronto) gave details of their extensive experience with product commercialization while holding primary appointments in academic departments. They both encouraged strong clinical input at very early stages of research. Neurosurgeon Fady Charbel, MD, (Department of Neurosurgery at the University of Illinois at Chicago) discussed his role in product commercialization as a clinician. Todd Kuiken, MD, PhD, (Director of the Neural Engineering for Artificial Limbs at the Rehabilitation Institute of Chicago, affiliated with Northwestern University) also a clinician, described a model of translational engineering that emphasized the development of clinically relevant technology, without a strong commercialization imperative. The clinicians emphasized the importance of communicating effectively with engineers. Representing commercial neural engineering was Doug Sheffield, PhD, (Director of New Technology at Vertis Neuroscience, Inc.) who strongly encouraged open industrial academic partnerships as an efficient path forward in the translational process. Joe Pancrazio, PhD, a Program Director at NIH's National Institute of Neurological Disorders and Stroke, emphasized that NIH funding for translational research was aimed at breaking down scientific barriers to clinic entrance. Vivian Weil, PhD, (Director of Center for the Study of Ethics in the Professions at the Illinois Institute of Technology) a specialist on ethics in science and engineering, spoke of the usefulness of developing a code of ethics for addressing ethical aspects of translation from the bench to clinical implementation and of translation across disciplines in multi-disciplinary projects. Finally, the patient perspective was represented by Mr Jesse Sullivan. A double-arm amputee and patient of Dr Kuiken's, Mr Sullivan demonstrated the critically important role of the patient in successful translational neural engineering research.

    Phenomenon: Transfer of learning between classroom and workplace appears to be difficult. Various conceptions about learning in either the classroom or the workplace exist among stakeholders, yet little is known about their conceptions of the transfer of learning between both settings. This study explored stakeholders' conceptions about transfer of learning between classroom-based learning and workplace practice. Homogeneous focus groups with students, medical teachers, and workplace supervisors were conducted using a constructivist grounded theory approach. The 54 participants' conceptions mainly related to their beliefs about who was responsible for (a) preparing for transfer of learning, (b) being at the workplace and connecting back to classroom-based learning, and (c) reflecting on transfer of learning and continuing the process. A continuum was recognized between those who held medical teachers/workplace supervisors responsible and those who held students responsible. Insights: There appears to be a variety of conceptions about who is responsible for enabling the transfer process. These conceptions may influence learning and instructional activities. Hence, it may be necessary to make these beliefs explicit in order to better align stakeholders' conceptions. To this end, the conceptual framework created in this study may be a useful tool.

  1. Universal health coverage from multiple perspectives: a synthesis of conceptual literature and global debates.

    2015-07-04

    There is an emerging global consensus on the importance of universal health coverage (UHC), but no unanimity on the conceptual definition and scope of UHC, whether UHC is achievable or not, how to move towards it, common indicators for measuring its progress, and its long-term sustainability. This has resulted in various interpretations of the concept, emanating from different disciplinary perspectives. This paper discusses the various dimensions of UHC emerging from these interpretations and argues for the need to pay attention to the complex interactions across the various components of a health system in the pursuit of UHC as a legal human rights issue. The literature presents UHC as a multi-dimensional concept, operationalized in terms of universal population coverage, universal financial protection, and universal access to quality health care, anchored on the basis of health care as an international legal obligation grounded in international human rights laws. As a legal concept, UHC implies the existence of a legal framework that mandates national governments to provide health care to all residents while compelling the international community to support poor nations in implementing this right. As a humanitarian social concept, UHC aims at achieving universal population coverage by enrolling all residents into health-related social security systems and securing equitable entitlements to the benefits from the health system for all. As a health economics concept, UHC guarantees financial protection by providing a shield against the catastrophic and impoverishing consequences of out-of-pocket expenditure, through the implementation of pooled prepaid financing systems. As a public health concept, UHC has attracted several controversies regarding which services should be covered: comprehensive services vs. minimum basic package, and priority disease-specific interventions vs. primary health care. As a multi-dimensional concept, grounded in international human rights laws, the move towards UHC in LMICs requires all states to effectively recognize the right to health in their national constitutions. It also requires a human rights-focused integrated approach to health service delivery that recognizes the health system as a complex phenomenon with interlinked functional units whose effective interaction are essential to reach the equilibrium called UHC.

    How can the perspectives, insights and interests of young children, under 6 years-old, be given status in processes of change? This paper will examine the contribution participatory and visual methods can make to enabling young children to document their experiences and to facilitate exchange with adults. Examples will be drawn from three research studies in educational settings which have developed a specific research method, the Mosaic approach (Clark and Moss 2001; Clark 2004; Clark 2005) which brings together visual and verbal research tools. This paper will discuss how researching with young children rather than on young children can redraw the boundaries between adults' and children's roles in the research process including the relationship with the research audience.

Der Facettenreichtum der Aufsatzthemen entspricht dem im Titelkompositum „Unrechtserfahrungen“ ausgedrückten Spannungsverhältnis: Zum einen wird anhand von konkret erlebten Einzelschicksalen und von Darstellungen in der Literatur die Erfahrung von Ungerechtigkeit und Unrecht problematisiert. Zum anderen wird die rechtliche Begrifflichkeit genauer untersucht. Die Autorinnen kommen aus den Bereichen Philologie, Rechts- und Geschichtswissenschaft. Entsprechend bietet der Band eine vielfältige und insgesamt ergiebige Gesamtschau auf die Unrechtserfahrungen von Frauen in Vergangenheit und Gegenwart.This collected volume of eight essays tackles the experience of injustice specific to women. It was born out of an interdisciplinary colloquium during the winter semester of 2004/2005 at the Cornelia Goethe Center for Women’s Studies and the Study of Gender Relations (CGC. The richly varied themes of the essays correspond to the tension expressed in the composite word in the title “unjust-experience”: For one, the volume problematizes the experience of inequality and injustice through individual concrete experience and through literary presentations. In addition, it examines legal terminology in detail. The authors come from the wide-ranging areas of philology, law, and history. Accordingly, the volume offers a diverse and altogether rich overview of women’s experiences of injustice in the past and the present.

    We discuss the historical context for explorations of “pristine inner experience,” attempts to apprehend and describe the inner experiences that directly present themselves in natural environments. There is no generally accepted method for determining whether such apprehensions/descriptions should be considered high fidelity. By analogy from musical recording, we present and discuss one strategy for establishing experiential fidelity: the examining of brain activation associated with a variety of experiential perspectives that had not been specified at the time of data collection. We beeped participants in an fMRI scanner at randomly-determined times and recorded time-locked brain activations. We used Descriptive Experience Sampling (DES) to apprehend and describe the participant's experience that was ongoing at each beep. These apprehensions/descriptions were obtained with no specific theoretical perspective or experimental intention when originally collected. If these apprehensions/descriptions were of high fidelity, then these pairings of moments of experience and brain activations should be able to be productively examined and re-examined in multiple ways and from multiple theoretical perspectives. We discuss a small set of such re-examinations and conclude that this strategy is worthy of further examination. PMID:28191000

    Summer 2012 was very wet in northern Europe, and unusually dry and hot in southern Europe. We use multiple approaches to determine whether anthropogenic forcing made the extreme European summer of 2012 more likely. Using a number of observation- and model-based methods, we find that there was an anthropogenic contribution to the extremes in southern Europe, with a qualitative consensus across all methodologies. There was a consensus across the methodologies that there has been a significant increase in the risk of hot summers in southern Europe with climate change. Most approaches also suggested a slight drying, but none of the results were statistically significant. The unusually wet summer in northern Europe was made more likely by the observed atmospheric circulation pattern in 2012, but no evidence was found for a long-term trend in circulation.

Although elderly PReCaP patients demonstrated slightly better cognitive functioning (Mini Mental State Examination; 0.4 [95% confidence interval (CI) 0.2-0.6]), lower depression (Geriatric Depression Scale 15; -0.9 [95% -1.1 to -0.6]), and higher perceived health (Short-form 20; 5.6 [95% CI 2.8-8.4]) 1 year after admission than control patients, the clinical relevance was limited. Therefore, this study aims to identify factors impacting on the effectiveness of the implementation of the PReCaPand geriatric care 'as usual'. We conducted semi-structured interviews with 34 professionals working with elderly patients in three hospitals, selected for their comparable patient case mix and different levels of geriatric care. Five non-participatory observations were undertaken during multidisciplinary meetings. Patient files (n = 42), hospital protocols, and care plans were screened for elements of geriatric care. Clinical process data were analysed for PReCaP components. The establishment of a geriatric unit and employment of geriatricians demonstrates commitment to geriatric care in hospital A. Although admission processes are comparable, early identification of frail elderly patients only takes place in hosptial A. Furthermore, nursing care in the hospital A geriatric unit excels with regard to maximizing patient independency, an important predictor for hospital-related functional decline. Transfer nurses play a key role in arranging post-discharge geriatric follow-up care. Geriatric consultations are performed by geriatricians, geriatric nurses, and PReCaP case managers in hospital A. Yet hospital B consultative psychiatric nurses provide similar consultation services. The combination of standardized procedures, formalized communication channels, and advanced computerization contributes significantly to geriatric care in hospital B. Nevertheless, a small size hospital (hospital C) provides informal opportunities for information sharing and decision making, which are essential in geriatric care, given its multidisciplinary nature. Geriatric care for patients with multimorbidity requires a multidisciplinary approach in a geriatric unit. Geriatric care, which integrates medical and reactivation treatment, by means of early screening of risk factors for functional decline, promotion of physical activity, and adequate discharge planning, potentially reduces the incidence of functional decline in elderly patients. Yet low treatment fidelity played a major role in the ineffective implementation of the PReCaP. Treatment fidelity issues are caused by various factors, including the complexity of projects, limited attention for implementation, and inadequate interdisciplinary communication. © 2016 The Authors The International Journal of Health Planning and Management Published by John Wiley & Sons Ltd. © 2016 The Authors The International Journal of Health Planning and Management Published by John Wiley & Sons Ltd.

    2013-05-01

    Multidisciplinary rapid response teams focus on patients' emergent needs and manage critical situations to prevent avoidable deaths. Although research has focused primarily on outcomes, studies of the actual team effectiveness within the teams from multiple perspectives have been limited. To describe effectiveness of rapid response teams in a large teaching hospital in California that had been using such teams for 5 years. The grounded-theory method was used to discover if substantive theory might emerge from interview and/or observational data. Purposeful sampling was used to conduct in-person semistructured interviews with 17 key informants. Convenience sampling was used for the 9 observed events that involved a rapid response team. Analysis involved use of a concept or indicator model to generate empirical results from the data. Data were coded, compared, and contrasted, and, when appropriate, relationships between concepts were formed. Results Dimensions of effective team performance included the concepts of organizational culture, team structure, expertise, communication, and teamwork. Professionals involved reported that rapid response teams functioned well in managing patients at risk or in crisis; however, unique challenges were identified. Teams were loosely coupled because of the inconsistency of team members from day to day. Team members had little opportunity to develop relationships or team skills. The need for team training may be greater than that among teams that work together regularly under less time pressure to perform. Communication between team members and managing a crisis were critical aspects of an effective response team.

  10. Ecological literacy materials for use in elementary schools: A critical analysis

    Science.gov (United States)

    Chambers, Joan Maureen

    My research is a critical examination of environmental science education resources for use in Alberta schools. I examine both the resources and the processes by which these resources are developed by diverse groups. My inquiry is guided by the following question: What is the nature of the discourse of ecological literacy in the promotion and content of teaching materials in elementary schools in Alberta? This critical analysis centres on the discourses, language, and perspectives (both hidden and overt) of these resources and processes; the manifestation of political agendas; existing relations; and the inclusion or exclusion of alternate views. Framed within critical theory and an ecosocial construct, my methodology employs critical discourse analysis and hermeneutic interpretation. I analyse selected environmental science resources produced for the elementary classroom by government and nongovernment organizations. I also interview the producers and/or writers of these instructional resources to provide the perspectives of some of the developers of these materials. The findings illustrate how the discursive management of the view of nature, human-nature relationships, uncertainty, multiple perspectives, and dimensions of ecological literacy in materials for schools offer students a particular perspective. These ecological and science discourses act to shape their personal relationships with nature and notions of environmental responsibility and consciousness. This research is necessary because, particularly in Alberta, corporate interests have the potential to impact school curricula. The study points to a need for a critical appraisal of resources for schools produced by the environmental science community.

  11. Examining Elementary Teachers' Identities through Analysis of Student Science Notebooks

    Madden, Lauren

    2011-12-01

    The purpose of this study is to understand how teacher identity influences elementary teachers' science practices from multiple perspectives---the teacher's self-reported identity, the researcher's perspective, and the students' perspectives. Two frameworks on identity were synthesized and used in this research. The first, developed by Gee (2000-01) examines who a teacher is with respect to four areas: nature, institution, discourse, and affinity group belonging. The second, developed by Beijaard, Verloop, and Vermunt (2000) examines factors that drive what a teacher does in his/her practice through examining teachers' expertise divided among three areas: content, pedagogy, and didactics. These frameworks were used to guide interpretation of the data sources in order to better understand how instruction unfolded. The science instruction of one class of second grade students receiving science instruction from three different teachers was studied over the course of one school year. The first manuscript of this study is a qualitative case study describing the three teachers' identities and practices from the perspective of the teacher, researcher, and students. Classroom observations, teacher interviews and questionnaires, and student interviews were coded thematically using identity markers as themes. These data sources were triangulated to reveal differences in both the identities and practices among the three teachers. For two of the three teachers, their self-described identities were different from how they were viewed by their students and the researcher. These findings highlight the importance of incorporating multiple perspectives, including those of students, when describing teachers' practices and identities. The study revealed that the three experienced teachers at the same grade level had vastly different science needs, underscoring the utility of identity theory for the design of professional development efforts. The second manuscript of this study is a

    This special issue on gender-related content analysis is the second of two parts (see Rudy et al. 2010b). The current special issue is more diverse than was the first in the number of countries that are represented and in the variety of media genres and content types that are included. The primary aim of this paper is to outline some of the contributions of the individual papers in this second special issue. Some of these advancements and innovations include (a) examining underresearched measures, countries, time spans, sexual orientations, and individual media programs; (b) addressing both international and intranational differences in gender-role portrayals; (c) comparing multiple content formats within the same media unit; (d) updating past findings to take into consideration the current media landscape; (e) employing established measures in novel ways and novel contexts; (f) uncovering limitations in established intercultural measures and media-effects theories; (g) suggesting variables that could predict additional differences in gender-role portrayals; (h) adopting virtually identical methods and measures across distinct content categories in order to facilitate comparisons; (i) conducting multiple tests of a given hypothesis; (j) examining, from multiple perspectives, the implications of racial differences in gender portrayals; and (k) examining the implications of underrepresentation of women and the perspectives that women hold. In addition to the original content-analytical research presented in this special issue, two reviews, one methodological and the other analytical, offer recommendations of procedures and perspectives to be implemented in future research.

    2010-01-01

    We introduce a new visual analytic approach to the study of scientific discoveries and knowledge diffusion. Our approach enhances contemporary co-citation network analysis by enabling analysts to identify co-citation clusters of cited references intuitively, synthesize thematic contexts in which these clusters are cited, and trace how research focus evolves over time. The new approach integrates and streamlines a few previously isolated techniques such as spectral clustering and feature selection algorithms. The integrative procedure is expected to empower and strengthen analytical and sense making capabilities of scientists, learners, and researchers to understand the dynamics of the evolution of scientific domains in a wide range of scientific fields, science studies, and science policy evaluation and planning. We demonstrate the potential of our approach through a visual analysis of the evolution of astronomical research associated with the Sloan Digital Sky Survey (SDSS) using bibliographic data between 1...

    To investigate the ability of column (or partial column) information to represent surface air quality, results of linear regression analyses between surface mixing ratio data and column abundances for O3 and NO2 are presented for the July 2011 Maryland deployment of the DISCOVER-AQ mission. Data collected by the P-3B aircraft, ground-based Pandora spectrometers, Aura/OMI satellite instrument, and simulations for July 2011 from the CMAQ air quality model during this deployment provide a large and varied data set, allowing this problem to be approached from multiple perspectives. O3 columns typically exhibited a statistically significant and high degree of correlation with surface data (R(sup 2) > 0.64) in the P- 3B data set, a moderate degree of correlation (0.16 < R(sup 2) < 0.64) in the CMAQ data set, and a low degree of correlation (R(sup 2) < 0.16) in the Pandora and OMI data sets. NO2 columns typically exhibited a low to moderate degree of correlation with surface data in each data set. The results of linear regression analyses for O3 exhibited smaller errors relative to the observations than NO2 regressions. These results suggest that O3 partial column observations from future satellite instruments with sufficient sensitivity to the lower troposphere can be meaningful for surface air quality analysis.

    Designing preventive programs relevant to vector-borne diseases such as Lyme disease (LD) can be complex given the need to include multiple issues and perspectives into prioritizing public health actions. A multi-criteria decision aid (MCDA) model was previously used to rank interventions for LD prevention in Quebec, Canada, where the disease is emerging. The aim of the current study was to adapt and evaluate the decision model constructed in Quebec under a different epidemiological context, in Switzerland, where LD has been endemic for the last thirty years. The model adaptation was undertaken with a group of Swiss stakeholders using a participatory approach. The PROMETHEE method was used for multi-criteria analysis. Key elements and results of the MCDA model are described and contrasted with the Quebec model. All criteria and most interventions of the MCDA model developed for LD prevention in Quebec were directly transferable to the Swiss context. Four new decision criteria were added, and the list of proposed interventions was modified. Based on the overall group ranking, interventions targeting human populations were prioritized in the Swiss model, with the top ranked action being the implementation of a large communication campaign. The addition of criteria did not significantly alter the intervention rankings, but increased the capacity of the model to discriminate between highest and lowest ranked interventions. The current study suggests that beyond the specificity of the MCDA models developed for Quebec and Switzerland, their general structure captures the fundamental and common issues that characterize the complexity of vector-borne disease prevention. These results should encourage public health organizations to adapt, use and share MCDA models as an effective and functional approach to enable the integration of multiple perspectives and considerations in the prevention and control of complex public health issues such as Lyme disease or other vector

    Event reasoning requires support of commonsense event knowledge. We proposed a method of event knowledge analysis in order to analysize preconditions and effects of events from multiple perspectives. In the process of analysis we followed three phases: fundamental analysis,knowledge supplement,and knowledge optimization. We summarized four common sense knowledge dimensions to solve the problem of comprehensiveness and accuracy in analysis, which are physiological,psychological,social and physical. The method of role specification was proposed in the knowledge supplement phase. Experiments show that this method is promising for acquiring comprehensive and accurate commonsense event knowledge.%事件推理的研究需要事件的知识作支撑.事件知识作为一种常识性知识,其获取仍然是知识获取的瓶颈.提出一种事件知识分析方法,以从多个视角分析事件的前提和后果知识.在对事件知识分析中遵循基础分析、知识丰富、知识优化的流程.针对分析过程中所得知识不够全面和准确的问题,总结得出生理、心理、社会、物理世界4个常识知识角度,同时在知识丰富步骤中提出了角色细化的方法.实验表明,此方法能够得到较为全面和准确的事件知识.

    of multiple perspectives. In general, less comprehensive ways of experiencing the phenomenon include seeking information to make the problem more well-structured and thereby allowing the completion of a classroom task. Movement towards more comprehensive ways of experiencing include accepting ambiguity as inherent to the problem, and utilizing multiple perceptions to develop a design solution. The most comprehensive ways of experiencing included experiences that embraced ambiguity as an integral part of the problem solving process and internalized multiple perspectives through working with and learning from others. The resulting outcome space is of practical use to engineering educators who wish to create more inclusive and effective cornerstone design learning environments. The findings demonstrate that significant variation is present in the way that a small group of first-year engineering students from a single university experience engaging with problems that involve multiple possible solutions. Powerful ways of experiencing this crucial aspect of engineering education include appreciation of the multiple ways of perceiving an ill-structured problem as well as an ability to accept the ambiguity that is associated with engaging with these types of problems. While some students are capable of such an experience, others do seek a single correct answer through an attempt to eliminate ambiguity. Knowing these key axes of variation informs educators' ability to accommodate a range of ways of experiencing design tasks and to design learning environments that foster development in these identified aspects of the experience to promote more meaningful learning experiences.

    Full Text Available Social housing requires appropriate evaluation models of projects, considering them from multiple perspectives: architectural, technical, environmental, economic, financial, paying particular attention to social aspects. The study proposes the use of a multi criteria evaluation model, based on the hierarchical (AHP and network (ANP analysis, as support in decision-making to guide practitioners and policy on the choice among alternative interventions. These methods allow to consider the overall effect of projects on urban system and the different points of view of those concerned, in an integrated and participatory approach. Interesting research perspectives concern the application of these evaluation approaches to case studies related to neighborhoods in which urban planning provides for social housing. The analysis will address the recent proposals for social housing in the city of Pescara (Italy, and in particular the urban transformation that is expected to achieve by means of the Integrated Urban Development Programme on the south-west of the city, whose regeneration was started by the Community Programme Urban 2.   Un’Analisi Multi Criteri per la Valutazione delle Proposte di Housing Sociale: dall’Analytic Hierarchy Process (AHP all’Analytic Network Process (ANP I modelli insediativi di social housing richiedono idonei strumenti valutativi degli interventi immobiliari, considerandoli da molteplici punti di vista: architettonici, urbanistici, ambientali, economici, finanziari, con particolare attenzione agli aspetti sociali.

    重视艺术与现实生活的密切联系,是丰子恺审美活动的逻辑起点。面对丰富的民俗生活和民俗事象,丰子恺从多角度、多层面展开民俗审美活动。在物质民俗审美中,丰子恺以对“人间烟火气”的盎然兴致,观察其家乡的衣食住行习俗,捕捉司空见惯的原生态民俗,刻画富于人情味和人情美的民俗生活。在艺术民俗审美中,不仅以玩具与花灯为代表的民间美术和民间工艺品是其民俗审美的重要内容,连日常生活中的叫卖声、小贩的招揽声、打桩的号子声也成了亲切而感人的“自然的音乐”,具有丰富的民俗文化价值。在信仰民俗审美中,他关注了家乡的佛道信仰、祖先崇拜及原始的动植物崇拜,通过对节日仪式的审美观照,展现了丰富的民间宗教信仰和原始巫术遗存。%Attaching importance to the close relationship between art and reality is the logical point of departure of Feng Zikai's aesthetic activities. Faced with a rich variety of folk customs and ways, Feng Zikai pursued his aesthetic appreciation of them from multi-angles and on multi-layers. When appreciating the material folk customs, he showed a keen interest in the everyday life of ordinary people, observing the daily habits of his country folks, taking note of pristine ways and customs which often escape an unobservant eye and depicting folk life that is filled with a human touch. When appreciating folk cus- toms of art, he not only studied typical arts and crafts like toys and festive lanterns, but also "the natural music" of crying one's ware, soliciting customers and chanting while piling that is rich in cultural value. When studying the folk customs of faith, he paid attention to the Buddhist and Taoist faiths of his country folks, their ancestor worship and their primitive wor- ship of animals and plants. Through an aesthetic appreciation of the festive rituals he revealed rich relics of folk religious be- liefs and primitive witchcraft.

    False confessions have been considered to be the result of interrogation pressure for a long time. People often neglect the fact that voluntary false confessions do exist in practice for all kinds of reasons and believe them to be true. Voluntary false confessions have the characteristics of initiative and concealment which will damage the criminal justice for its imperceptibility. Voluntary false confessions are affected by multiple factors including utilitarianism, psychological factors, personality and mental pathological factors, which are derived from the cultural and psychological basis such as the traditional culture, tool rationality and desire.%在刑讯逼供备受关注背景下,虚假的认罪供述往往被认为是警察审讯压力的结果。在趋利避害的本能下,人们忽视了实践中长期存在的无辜者自愿进行的虚假有罪供述,往往将其当成真实认罪供述。自愿型虚假供述具有的主动性、隐蔽性等特点给刑事司法带来危害。影响自愿型虚假供述的因素包括现实功利性因素、心理因素、人格与环境因素、精神病理因素等多方面,这些因素又具有传统文化中重亲情轻法律的消极思想、工具理性泛滥以及心理需求膨胀等文化、心理基础。

Like fuzzy logic, grey logic is useful in situations with incomplete and uncertain information. Grey analysis is particularly applicable in instances with very limited data and in cases with little system knowledge or understanding. In this paper, a summary of the basic concepts of grey analysis is provided, with descriptions of its application to several classes of problems. Calculations methods are provided for grey relation analysis, and for modeling and prediction using grey methods.

    Full Text Available Cloud computing has competitive advantages—such as on-demand self-service, rapid computing, cost reduction, and almost unlimited storage—that have attracted extensive attention from both academia and industry in recent years. Some review works have been reported to summarize extant studies related to cloud computing, but few analyze these studies based on the citations. Co-citation analysis can provide scholars a strong support to identify the intellectual bases and leading edges of a specific field. In addition, advanced algorithms, which can directly affect the availability, efficiency, and security of cloud computing, are the key to conducting computing across various clouds. Motivated by these observations, we conduct a specific visualization review of the studies related to cloud computing algorithms using one mainstream co-citation analysis tool—CiteSpace. The visualization results detect the most influential studies, journals, countries, institutions, and authors on cloud computing algorithms and reveal the intellectual bases and focuses of cloud computing algorithms in the literature, providing guidance for interested researchers to make further studies on cloud computing algorithms.

    2014-01-01

    Calcium antagonists are widely used in the clinical treatment of ischemic cerebrovascular disease because of their vascular and neuroprotective effects. Nimodipine, a typical calcium antagonist, can cross the blood-brain barrier and act selectively at neurons and blood vessels of target tis-sues, thus exerting neuroprotective effects. The aim of the present study was to explore the hot spots and future trends of research on the neuroprotective effects of nimodipine. We retrieved 425 articles on the neuroprotective effects of nimodipine that were indexed in the Web of the Science database between 2000 and 2014. The retrieved articles were analyzed using document analysis reporting and the derived information function in the Web of Science, and the infor-mation visualization software CiteSpace III. The reference co-citation network was plotted, and the high frequency key words in these publications were used to analyze the research fronts and development trends for nimodipine neuroprotection. According to these co-citation clusters, the research front of nimodipine neuroprotection is the use of randomized controlled trials to study nimodipine intervention of subarachnoid hemorrhage. Using time zone view analysis on hot spots labeled with a key word, the areas of interest in the ifeld of nimodipine neuroprotection are nimodipine pharmacology and therapeutics, blood-brain barrier, trials, and anti-angiospasm.

    Based on our 2013-article, ”Does Deployment to War Affect Soldiers' Public Service Motivation – A Panel Study of Soldiers Before and After their Service in Afghanistan”, we present Panel Analysis as a methodological discipline. Panels consist of multiple units of analysis, observed at two or more...... in research settings where it is not possible to distribute units of analysis randomly or where the independent variables cannot be manipulated. The greatest disadvantage in regard to using panel studies is that data may be difficult to obtain. This is most clearly vivid in regard to the use of panel surveys...

  4. Analysis II

    Tao, Terence

    2016-01-01

    This is part two of a two-volume book on real analysis and is intended for senior undergraduate students of mathematics who have already been exposed to calculus. The emphasis is on rigour and foundations of analysis. Beginning with the construction of the number systems and set theory, the book discusses the basics of analysis (limits, series, continuity, differentiation, Riemann integration), through to power series, several variable calculus and Fourier analysis, and then finally the Lebesgue integral. These are almost entirely set in the concrete setting of the real line and Euclidean spaces, although there is some material on abstract metric and topological spaces. The book also has appendices on mathematical logic and the decimal system. The entire text (omitting some less central topics) can be taught in two quarters of 25–30 lectures each. The course material is deeply intertwined with the exercises, as it is intended that the student actively learn the material (and practice thinking and writing ri...

    Jacques, Ian

    1987-01-01

    This book is primarily intended for undergraduates in mathematics, the physical sciences and engineering. It introduces students to most of the techniques forming the core component of courses in numerical analysis. The text is divided into eight chapters which are largely self-contained. However, with a subject as intricately woven as mathematics, there is inevitably some interdependence between them. The level of difficulty varies and, although emphasis is firmly placed on the methods themselves rather than their analysis, we have not hesitated to include theoretical material when we consider it to be sufficiently interesting. However, it should be possible to omit those parts that do seem daunting while still being able to follow the worked examples and to tackle the exercises accompanying each section. Familiarity with the basic results of analysis and linear algebra is assumed since these are normally taught in first courses on mathematical methods. For reference purposes a list of theorems used in the t...

    This textbook is designed for a year-long course in real analysis taken by beginning graduate and advanced undergraduate students in mathematics and other areas such as statistics, engineering, and economics. Written by one of the leading scholars in the field, it elegantly explores the core concepts in real analysis and introduces new, accessible methods for both students and instructors. The first half of the book develops both Lebesgue measure and, with essentially no additional work for the student, general Borel measures for the real line. Notation indicates when a result holds only for Lebesgue measure. Differentiation and absolute continuity are presented using a local maximal function, resulting in an exposition that is both simpler and more general than the traditional approach. The second half deals with general measures and functional analysis, including Hilbert spaces, Fourier series, and the Riesz representation theorem for positive linear functionals on continuous functions with compact support....

    the authors from Chinese Academy of Fishery Sciences experienced great growth. The authors involved in genetic breeding published the most articles. The most key words were micro-satellite, gene clone, gene expression and sequence analysis which present the current research focuses. Trait-related gene, pedigree identification, karyotype, genome and gynogenesis were the emerging key words which indicated new research field. Core authors were selected out and co-citation between authors were analyzed using the method of social network analysis. From the above, it could be concluded that in recent years, the number of biotechnology articles published by the authors from Chinese Academy of Fishery Sciences increased steadily, and domestic paper number was much higher than international ones. Bioteehniques such as micro-satellite were widely used and promoted great improvement of genetic diversity and genetic breeding. Close relationship between researchers had not came into being yet and the research production and research influence did not distributed equilibriumly in every institute of Chinese Academy of Fishery Sciences.

    The guiding principle of this presentation of ``Classical Complex Analysis'' is to proceed as quickly as possible to the central results while using a small number of notions and concepts from other fields. Thus the prerequisites for understanding this book are minimal; only elementary facts of calculus and algebra are required. The first four chapters cover the essential core of complex analysis: - differentiation in C (including elementary facts about conformal mappings) - integration in C (including complex line integrals, Cauchy's Integral Theorem, and the Integral Formulas) - sequences and series of analytic functions, (isolated) singularities, Laurent series, calculus of residues - construction of analytic functions: the gamma function, Weierstrass' Factorization Theorem, Mittag-Leffler Partial Fraction Decomposition, and -as a particular highlight- the Riemann Mapping Theorem, which characterizes the simply connected domains in C. Further topics included are: - the theory of elliptic functions based on...

    We describe the subject of Cosmic Microwave Background (CMB) analysis - its past, present and future. The theory of Gaussian primary anisotropies, those arising from linear physics operating in the early Universe, is in reasonably good shape so the focus has shifted to the statistical pipeline which confronts the data with the theory: mapping, filtering, comparing, cleaning, compressing, forecasting, estimating. There have been many algorithmic advances in the analysis pipeline in recent years, but still more are needed for the forecasts of high precision cosmic parameter estimation to be realized. For secondary anisotropies, those arising once nonlinearity develops, the computational state of the art currently needs effort in all the areas: the Sunyaev-Zeldovich effect, inhomogeneous reionization, gravitational lensing, the Rees-Sciama effect, dusty galaxies. We use the Sunyaev-Zeldovich example to illustrate the issues. The direct interface with observations for these non-Gaussian signals is much more compl...

    Full Text Available Gallstone is a crystal deposit which is formed in the gallbladder or bile duct. Gallstone is classified into cholesterol stone, pigment stone (black and brown, and mixed stone. Mechanism which underlies the formation of cholesterol or pigment gallstone is different. Information on chemical component of the stone will assist the management and prevention of its recurrence. Analysis of gallstone component can be performed by colorimetry method or even gas liquid chromatography (GLC. Chemical component analysis of gallstone by colorimetry includes examination of cholesterol, bilirubin, and calcium. Stone is classified as cholesterol stone if the cholesterol content is > 80%, pigment stone if cholesterol content is < 20%, and mixed stone if cholesterol content is 25-80%. Gallstone analysis by GLC method is conducted by separation of fatty acid chain and evaluation of fatty acid quantity in the methylester derivatives form, which is fatty acid methyl estered. Fatty acid content in cholesterol stone (310.09 + 49.7 mg/gram is higher compared to pigment stone (55.59 +7.71 mg/gram. Saturated to unsaturated fatty acid (S/U ration in cholesterol stone (8.6 + 3.1 is higher compared to pigment stone (4.8 + 1.5.

EPCA requires that standards be designed to achieve the maximum improvement in energy efficiency that is technologically feasible and economically justified. Following the introductory chapter, Chapter Two describes the methodology used in the economic analysis and its relationship to legislative criteria for consumer product efficiency assessment; details how the CPES Value Model systematically compared and evaluated the economic impacts of regulation on the consumer, manufacturer and Nation. Chapter Three briefly displays the results of the analysis and lists the proposed performance standards by product class. Chapter Four describes the reasons for developing a baseline forecast, characterizes the baseline scenario from which regulatory impacts were calculated and summarizes the primary models, data sources and assumptions used in the baseline formulations. Chapter Five summarizes the methodology used to calculate regulatory impacts; describes the impacts of energy performance standards relative to the baseline discussed in Chapter Four. Also discussed are regional standards and other program alternatives to performance standards. Chapter Six describes the procedure for balancing consumer, manufacturer, and national impacts to select standard levels. Details of models and data bases used in the analysis are included in Appendices A through K.

    In 1943, while in charge of Columbia University's Statistical Research Group, Abraham Wald devised Sequential Design, an innovative statistical inference system. Because the decision to terminate an experiment is not predetermined, sequential analysis can arrive at a decision much sooner and with substantially fewer observations than equally reliable test procedures based on a predetermined number of observations. The system's immense value was immediately recognized, and its use was restricted to wartime research and procedures. In 1945, it was released to the public and has since revolutio

      As the development of the global communication all over the world, English has become the international language for the global communication. Furthermore, speaking as a skill in English language learning becomes more and more important. As it is known, spoken English has specific features, thus to gain an explicit understanding of the features data analysis is helpful. Moreover it is useful for language teacher to make development in teaching to satisfy learner’s needs. Grammatical and phonological are the two remarkable aspects and specific features in spoken language therefore to discover elements into these aspects seems helpful to teaching spoken Enlgish.

    Abbott, Stephen

    2015-01-01

    This lively introductory text exposes the student to the rewards of a rigorous study of functions of a real variable. In each chapter, informal discussions of questions that give analysis its inherent fascination are followed by precise, but not overly formal, developments of the techniques needed to make sense of them. By focusing on the unifying themes of approximation and the resolution of paradoxes that arise in the transition from the finite to the infinite, the text turns what could be a daunting cascade of definitions and theorems into a coherent and engaging progression of ideas. Acutely aware of the need for rigor, the student is much better prepared to understand what constitutes a proper mathematical proof and how to write one. Fifteen years of classroom experience with the first edition of Understanding Analysis have solidified and refined the central narrative of the second edition. Roughly 150 new exercises join a selection of the best exercises from the first edition, and three more project-sty...

    The input-output table is comprehensive and detailed in describing the national economic system with complex economic relationships, which embodies information of supply and demand among industrial sectors. This paper aims to scale the degree of competition/collaboration on the global value chain from the perspective of econophysics. Global Industrial Strongest Relevant Network models were established by extracting the strongest and most immediate industrial relevance in the global economic system with inter-country input-output tables and then transformed into Global Industrial Resource Competition Network/Global Industrial Production Collaboration Network models embodying the competitive/collaborative relationships based on bibliographic coupling/co-citation approach. Three indicators well suited for these two kinds of weighted and non-directed networks with self-loops were introduced, including unit weight for competitive/collaborative power, disparity in the weight for competitive/collaborative amplitude and weighted clustering coefficient for competitive/collaborative intensity. Finally, these models and indicators were further applied to empirically analyze the function of sectors in the latest World Input-Output Database, to reveal inter-sector competitive/collaborative status during the economic globalization.

    1997-01-01

    A good part of matrix theory is functional analytic in spirit. This statement can be turned around. There are many problems in operator theory, where most of the complexities and subtleties are present in the finite-dimensional case. My purpose in writing this book is to present a systematic treatment of methods that are useful in the study of such problems. This book is intended for use as a text for upper division and gradu­ ate courses. Courses based on parts of the material have been given by me at the Indian Statistical Institute and at the University of Toronto (in collaboration with Chandler Davis). The book should also be useful as a reference for research workers in linear algebra, operator theory, mathe­ matical physics and numerical analysis. A possible subtitle of this book could be Matrix Inequalities. A reader who works through the book should expect to become proficient in the art of deriving such inequalities. Other authors have compared this art to that of cutting diamonds. One first has to...

  8. Uncertainty analysis

    Energy Technology Data Exchange (ETDEWEB)

    Thomas, R.E.

    1982-03-01

    An evaluation is made of the suitability of analytical and statistical sampling methods for making uncertainty analyses. The adjoint method is found to be well-suited for obtaining sensitivity coefficients for computer programs involving large numbers of equations and input parameters. For this purpose the Latin Hypercube Sampling method is found to be inferior to conventional experimental designs. The Latin hypercube method can be used to estimate output probability density functions, but requires supplementary rank transformations followed by stepwise regression to obtain uncertainty information on individual input parameters. A simple Cork and Bottle problem is used to illustrate the efficiency of the adjoint method relative to certain statistical sampling methods. For linear models of the form Ax=b it is shown that a complete adjoint sensitivity analysis can be made without formulating and solving the adjoint problem. This can be done either by using a special type of statistical sampling or by reformulating the primal problem and using suitable linear programming software.

    Kunz, Werner; Manning, Stephan; Pedersen, Torben

    2013-01-01

    This study examines the evolution of the field of international business (IB) research based on a relational cluster analysis of co-citations in the Journal of International Business Studies (JIBS) from 1982 to 2011. Particularly, we examine the changing role of theory in relation to empirical IB...... research. Based on a factor and network analysis, we identify distinct clusters of IB research and their relations over time. We show that the initial focus of IB research on issues of international expansion has shifted towards issues of governance and implementation. In this process, debates on foreign...... entry mode and culture have served as important integrating themes. At the same time, theory debates in IB have expanded from a narrow focus on explaining international expansion, to a rather heterogeneous conglomerate of approaches which have assisted increasingly differentiated empirical research.

Based on the discussion,this paper reveals the substan-tive meaning of the End of Art of Hegel that is on no aspect did Hegel say with certainty what the end or even the death of art was. Only on the perspective of social reality,Hegel held some pessimistic points of view toward the de-velopment of art which were due to his failure to realize that art is just the best way to mediate the contradiction be-tween men and the society,also the inner need to be poetic to perch on the earth. Therefore,there is no end or death of art.

We observed that there are clear differences in the number and interdisciplinary spread of competencies across regions: the USA retains the largest capacity and capability for pursuing medical and pharmaceutical applications; China has shown substantial growth through fusion approaches with chemistry and material sciences; Japan has been pursuing basic biology and is currently seeking further growth; and the UK has shown considerable growth and quality with a focus on medical research and the widest interdisciplinary spread. Furthermore, we discuss policy implications from these results in terms of industrial and clinical applications. These findings provide a rational way of evaluating research policies and forecasting research trends.

As a new concept in ecological economics, emergy theory builds “a bridge between environment and economy” and unifies the quantification of material flow, energy flow, economic flow, population flow and information flow. Now emergy theory and its application have become hot domains in ecological economics, and emergy analysis method is also increasingly developing into a basic evaluation tool of eco-economic system. Firstly, based on data of literatures including theme of“emergy”collected from Web of Science during 1998 and 2013, statistical analysis of distribution about emergy research involved discipline, time, region and institution is given in this article, it is shown that number of literatures about emergy is on rise year by year, mainly focuses on subjects such as ecology, environmental science and energy, and research strength of emergy concentrates in Italy, China and USA. Univ Siena, Beijing Normal University, Peking University, Chinese Academy of Science, University of Florida and so on show stronger research strength of emergy. Then CiteSpace software is used to draw out the literature co-citation mapping knowledge domain to analyze knowledge foundation and influence of core authors of emergy. The mapping knowledge domain reveals that researchers such as Odum HT, Brown MT, Hau JL, Ulgiati S and so on have established solid basement of emergy research and pushed the research forward.

    NASA s Constellation Program employs a strategic analysis methodology in providing an integrated analysis capability of Lunar exploration scenarios and to support strategic decision-making regarding those scenarios. The strategic analysis methodology integrates the assessment of the major contributors to strategic objective satisfaction performance, affordability, and risk and captures the linkages and feedbacks between all three components. Strategic analysis supports strategic decision making by senior management through comparable analysis of alternative strategies, provision of a consistent set of high level value metrics, and the enabling of cost-benefit analysis. The tools developed to implement the strategic analysis methodology are not element design and sizing tools. Rather, these models evaluate strategic performance using predefined elements, imported into a library from expert-driven design/sizing tools or expert analysis. Specific components of the strategic analysis tool set include scenario definition, requirements generation, mission manifesting, scenario lifecycle costing, crew time analysis, objective satisfaction benefit, risk analysis, and probabilistic evaluation. Results from all components of strategic analysis are evaluated a set of pre-defined figures of merit (FOMs). These FOMs capture the high-level strategic characteristics of all scenarios and facilitate direct comparison of options. The strategic analysis methodology that is described in this paper has previously been applied to the Space Shuttle and International Space Station Programs and is now being used to support the development of the baseline Constellation Program lunar architecture. This paper will present an overview of the strategic analysis methodology and will present sample results from the application of the strategic analysis methodology to the Constellation Program lunar architecture.

    VISPA is a development environment for high energy physics analyses which enables physicists to combine graphical and textual work. A physics analysis cycle consists of prototyping, performing, and verifying the analysis. The main feature of VISPA is a multipurpose window for visual steering of analysis steps, creation of analysis templates, and browsing physics event data at different steps of an analysis. VISPA follows an experiment-independent approach and incorporates various tools for steering and controlling required in a typical analysis. Connection to different frameworks of high energy physics experiments is achieved by using different types of interfaces. We present the look-and-feel for an example physics analysis at the LHC and explain the underlying software concepts of VISPA.

    2011-01-01

    It is the development trend in international rivers management cooperation in the future to carry out effective regional cooperation and seek maximization of socio-economic and eco-environmental benefits from river basins. It is an important approach to systemically studying and correctly understanding the influencing factors on regional cooperation of international rivers for strengthening international rivers management cooperation. Based on the international regime theory and systematic analysis methodology, this study developed a comprehensive analysis framework (CAF) for analyzing the influencing factors on international rivers cooperation from multiple perspectives. Main influencing factors under the comprehensive analysis framework include the following: 1) characteristics and issues of international river systems; 2) interests claim of river basin countries; 3) political context; 4) external water related regimes; 5) other regional relevant cooperation regimes and institutions; 6) third party involvement; and 7) cultural and values. The fore two factors comprise the internal influencing factors of the CAF, and the sequent five factors comprise the external influencing factors of the CAF. All the factors directly influence the development of treaties and policies on international rivers management cooperation, institutional structure and capacity development, cooperative management approaches and methodologies. The different characteristics and regional context and conditions of different international rivers also determine the roles of various factors. The CAF methodology may be applied to analyze and assess a variety of international river regional cooperation practices, and then put forward improvement solutions.%开展有效的国际河流区域合作方式,寻求流域内外社会经济、生态环境效益的最大化,是国际河流开发与管理发展的趋势。系统掌握和正确理解影响国际河流区域合

    Science.gov (United States)

    1993-01-01

    This publication is primarily intended for use by NASA personnel engaged in managing or implementing trend analysis programs. 'Trend analysis' refers to the observation of current activity in the context of the past in order to infer the expected level of future activity. NASA trend analysis was divided into 5 categories: problem, performance, supportability, programmatic, and reliability. Problem trend analysis uncovers multiple occurrences of historical hardware or software problems or failures in order to focus future corrective action. Performance trend analysis observes changing levels of real-time or historical flight vehicle performance parameters such as temperatures, pressures, and flow rates as compared to specification or 'safe' limits. Supportability trend analysis assesses the adequacy of the spaceflight logistics system; example indicators are repair-turn-around time and parts stockage levels. Programmatic trend analysis uses quantitative indicators to evaluate the 'health' of NASA programs of all types. Finally, reliability trend analysis attempts to evaluate the growth of system reliability based on a decreasing rate of occurrence of hardware problems over time. Procedures for conducting all five types of trend analysis are provided in this publication, prepared through the joint efforts of the NASA Trend Analysis Working Group.

    The precision of an activation-analysis method prescribes the estimation of the precision of a single analytical result. The adequacy of these estimates to account for the observed variation between duplicate results from the analysis of different samples and materials, is tested by the statistic T......, which is shown to be approximated by a χ2 distribution. Application of this test to the results of determinations of manganese in human serum by a method of established precision, led to the detection of airborne pollution of the serum during the sampling process.

    This book provides a unique path for graduate or advanced undergraduate students to begin studying the rich subject of functional analysis with fewer prerequisites than is normally required. The text begins with a self-contained and highly efficient introduction to topology and measure theory, which focuses on the essential notions required for the study of functional analysis, and which are often buried within full-length overviews of the subjects. This is particularly useful for those in applied mathematics, engineering, or physics who need to have a firm grasp of functional analysis, but not necessarily some of the more abstruse aspects of topology and measure theory normally encountered. The reader is assumed to only have knowledge of basic real analysis, complex analysis, and algebra. The latter part of the text provides an outstanding treatment of Banach space theory and operator theory, covering topics not usually found together in other books on functional analysis. Written in a clear, concise manner,...

    兰国帅; 张一春; 王岚

    2014-01-01

    The constantly emerging new technologies and rapid development of modern educational technologies pro-mote great changes in educational technology. Since the new century began, governments aroud the world have paid extremely close attention to informationizing education. Although educational technology subjects in China develop quickly, they also encounter development bottlenecks. When facing the rapid development in this discipline and the challenge for the future development, domestic researchers in educational technology are eager to know the trend of ed-ucational technology research abroad in recent years intuitively, systematically, and comprehensively. Therefore, knowing the trend of educational research abroad, has become the part of daily academic activites of Chinese educa-tional technology researchers. Computer & Education ( C&E ) and British Journal of Educational Technology ( BJET) are two top-level academic journals in educational technology research. Papers published in the two journals reflect the trend of educational technology to a certain extent. It is helpful to know the tread of research in educational technology abroad by analyzing papers published in these two journals. As such, this paper conducts an in-depth a-nalysis and inquiry of papers published in the C&E and BJET from 2004 to 2013 . This paper collects data about the published papers, such as time distribution, country (region), high-yield academic institutions, high-yield and high-impact researchers and scholars, research topics, research focus, and to research methods, from Science Citation Database -WOS based on bibliometrics and social network analysis. Furthermore, this paper adopts information visu-alization software Bibexcelland NetDraw to conduct the co-citation and co-occurrence of knowledge map visualization analysis of the high influential scholars and keywords in the two journals. The results show that C&E concentrates on research topics, because there is a strong

  1. Gait analysis: clinical facts.

    Science.gov (United States)

    Baker, Richard; Esquenazi, Alberto; Benedetti, Maria G; Desloovere, Kaat

    2016-08-01

    Gait analysis is a well-established tool for the quantitative assessment of gait disturbances providing functional diagnosis, assessment for treatment planning, and monitoring of disease progress. There is a large volume of literature on the research use of gait analysis, but evidence on its clinical routine use supports a favorable cost-benefit ratio in a limited number of conditions. Initially gait analysis was introduced to clinical practice to improve the management of children with cerebral palsy. However, there is good evidence to extend its use to patients with various upper motor neuron diseases, and to lower limb amputation. Thereby, the methodology for properly conducting and interpreting the exam is of paramount relevance. Appropriateness of gait analysis prescription and reliability of data obtained are required in the clinical environment. This paper provides an overview on guidelines for managing a clinical gait analysis service and on the principal clinical domains of its application: cerebral palsy, stroke, traumatic brain injury and lower limb amputation.

  2. Robust Sparse Analysis Regularization

    CERN Document Server

    Vaiter, Samuel; Dossal, Charles; Fadili, Jalal

    2011-01-01

    This paper studies the properties of L1-analysis regularization for the resolution of linear inverse problems. Most previous works consider sparse synthesis priors where the sparsity is measured as the L1 norm of the coefficients that synthesize the signal in a given dictionary. In contrast, the more general analysis regularization minimizes the L1 norm of the correlations between the signal and the atoms in the dictionary. The corresponding variational problem includes several well-known regularizations such as the discrete total variation and the fused lasso. We first prove that a solution of analysis regularization is a piecewise affine function of the observations. Similarly, it is a piecewise affine function of the regularization parameter. This allows us to compute the degrees of freedom associated to sparse analysis estimators. Another contribution gives a sufficient condition to ensure that a signal is the unique solution of the analysis regularization when there is no noise in the observations. The s...

    2013-01-01

    The Norwegian Mapping Authority (NMA) has during the last few years had a close cooperation with Norwegian Defence Research Establishment (FFI) in the analysis of space geodetic data using the GEOSAT software. In 2012 NMA has taken over the full responsibility for the GEOSAT software. This implies that FFI stopped being an IVS Associate Analysis Center in 2012. NMA has been an IVS Associate Analysis Center since 28 October 2010. NMA's contributions to the IVS as an Analysis Centers focus primarily on routine production of session-by-session unconstrained and consistent normal equations by GEOSAT as input to the IVS combined solution. After the recent improvements, we expect that VLBI results produced with GEOSAT will be consistent with results from the other VLBI Analysis Centers to a satisfactory level.

  5. Asymptotic modal analysis and statistical energy analysis

    Science.gov (United States)

    Dowell, Earl H.

    1988-07-01

    Statistical Energy Analysis (SEA) is defined by considering the asymptotic limit of Classical Modal Analysis, an approach called Asymptotic Modal Analysis (AMA). The general approach is described for both structural and acoustical systems. The theoretical foundation is presented for structural systems, and experimental verification is presented for a structural plate responding to a random force. Work accomplished subsequent to the grant initiation focusses on the acoustic response of an interior cavity (i.e., an aircraft or spacecraft fuselage) with a portion of the wall vibrating in a large number of structural modes. First results were presented at the ASME Winter Annual Meeting in December, 1987, and accepted for publication in the Journal of Vibration, Acoustics, Stress and Reliability in Design. It is shown that asymptotically as the number of acoustic modes excited becomes large, the pressure level in the cavity becomes uniform except at the cavity boundaries. However, the mean square pressure at the cavity corner, edge and wall is, respectively, 8, 4, and 2 times the value in the cavity interior. Also it is shown that when the portion of the wall which is vibrating is near a cavity corner or edge, the response is significantly higher.

  6. Dynamics in Epistasis Analysis.

    Awdeh, Aseel; Phenix, Hilary; Kaern, Mads; Perkins, Theodore

    2017-01-16

    Finding regulatory relationships between genes, including the direction and nature of influence between them, is a fundamental challenge in the field of molecular genetics. One classical approach to this problem is epistasis analysis. Broadly speaking, epistasis analysis infers the regulatory relationships between a pair of genes in a genetic pathway by considering the patterns of change in an observable trait resulting from single and double deletion of genes. While classical epistasis analysis has yielded deep insights on numerous genetic pathways, it is not without limitations. Here, we explore the possibility of dynamic epistasis analysis, in which, in addition to performing genetic perturbations of a pathway, we drive the pathway by a time-varying upstream signal. We explore the theoretical power of dynamical epistasis analysis by conducting an identifiability analysis of Boolean models of genetic pathways, comparing static and dynamic approaches. We find that even relatively simple input dynamics greatly increases the power of epistasis analysis to discriminate alternative network structures. Further, we explore the question of experiment design, and show that a subset of short time-varying signals, which we call dynamic primitives, allow maximum discriminative power with a reduced number of experiments.

The organization of Canadian education in twelve autonomous educational jurisdictions is briefly described and problems are noted in relation to the analysis of curricula on a national scale. The international design for curriculum analysis is discussed and an alternative design, more suited to the diversity of science education in Canada, is introduced. The analysis of curriculum documents is described and three patterns which emerge from this analysis are identified. These derive from the concepts of commonality, specificity and prescriptiveness. Commonality relates to topics listed in curriculum guideline documents by a number of jurisdictions. Specificity refers to the richness of curriculum documents. Prescriptiveness is a measure of the extent to which jurisdictions do or do not make provision for local options in curriculum design. The Canadian analysis, using the concepts of the common curriculum, specificity and prescriptiveness, is described and research procedures are exemplified. Outcomes of curriculum analysis are presented in graphical form.

  8. Observations on risk analysis

    Energy Technology Data Exchange (ETDEWEB)

    Thompson, W.A. Jr.

    1979-11-01

    This paper briefly describes WASH 1400 and the Lewis report. It attempts to define basic concepts such as risk and risk analysis, common mode failure, and rare event. Several probabilistic models which go beyond the WASH 1400 methodology are introduced; the common characteristic of these models is that they recognize explicitly that risk analysis is time dependent whereas WASH 1400 takes a per demand failure rate approach which obscures the important fact that accidents are time related. Further, the presentation of a realistic risk analysis should recognize that there are various risks which compete with one another for the lives of the individuals at risk. A way of doing this is suggested.

    2001-02-01

    The concept of emergy and its use for comparing with energy were discussed in this paper. Emergy was defined as the amount of available energy required directly and indirectly to make a product or services, and emergy analysis was based on the solar emergy units (solar emjoules). Emergy provided the methodology with a common basis for measuring the value of different kinds of energy, and for evaluating the contributions from nature and humanity. A comparison of emergy analysis with previous energy analysis was also performed.

    Science.gov (United States)

    1990-01-01

    Structural Reliability Consultants' computer program creates graphic plots showing the statistical parameters of glue laminated timbers, or 'glulam.' The company president, Dr. Joseph Murphy, read in NASA Tech Briefs about work related to analysis of Space Shuttle surface tile strength performed for Johnson Space Center by Rockwell International Corporation. Analysis led to a theory of 'consistent tolerance bounds' for statistical distributions, applicable in industrial testing where statistical analysis can influence product development and use. Dr. Murphy then obtained the Tech Support Package that covers the subject in greater detail. The TSP became the basis for Dr. Murphy's computer program PC-DATA, which he is marketing commercially.

    BASIC Stress Analysis aims to help students to become proficient at BASIC programming by actually using it in an important engineering subject. It also enables the student to use computing as a means of learning stress analysis because writing a program is analogous to teaching-it is necessary to understand the subject matter. The book begins by introducing the BASIC approach and the concept of stress analysis at first- and second-year undergraduate level. Subsequent chapters contain a summary of relevant theory, worked examples containing computer programs, and a set of problems. Topics c

  13. Bayesian nonparametric data analysis

    CERN Document Server

    Müller, Peter; Jara, Alejandro; Hanson, Tim

    2015-01-01

    This book reviews nonparametric Bayesian methods and models that have proven useful in the context of data analysis. Rather than providing an encyclopedic review of probability models, the book’s structure follows a data analysis perspective. As such, the chapters are organized by traditional data analysis problems. In selecting specific nonparametric models, simpler and more traditional models are favored over specialized ones. The discussed methods are illustrated with a wealth of examples, including applications ranging from stylized examples to case studies from recent literature. The book also includes an extensive discussion of computational methods and details on their implementation. R code for many examples is included in on-line software pages.

    Shackelford, Carla; McNairy, Lisa; Wetherholt, Jon

    2009-01-01

    Commercial partnerships and organizational constraints, combined with complex systems, may lead to division of hazard analysis across organizations. This division could cause important hazards to be overlooked, causes to be missed, controls for a hazard to be incomplete, or verifications to be inefficient. Each organization s team must understand at least one level beyond the interface sufficiently enough to comprehend integrated hazards. This paper will discuss various ways to properly divide analysis among organizations. The Ares I launch vehicle integrated safety analyses effort will be utilized to illustrate an approach that addresses the key issues and concerns arising from multiple analysis responsibilities.

    The DOE Hydrogen Program is supporting research, development, and demonstration activities to overcome the barriers to the integration of hydrogen into the Nation`s energy infrastructure. Much work is required to gain acceptance of hydrogen energy system concepts and to develop them for implementation. A systems analysis database has been created that includes a formal documentation of technology characterization profiles and cost and performance information. Through a systematic and quantitative approach, system developers can understand and address important issues and thereby assure effective and timely commercial implementation. This project builds upon and expands the previously developed and tested pathway model and provides the basis for a consistent and objective analysis of all hydrogen energy concepts considered by the DOE Hydrogen Program Manager. This project can greatly accelerate the development of a system by minimizing the risk of costly design evolutions, and by stimulating discussions, feedback, and coordination of key players and allows them to assess the analysis, evaluate the trade-offs, and to address any emerging problem areas. Specific analytical studies will result in the validation of the competitive feasibility of the proposed system and identify system development needs. Systems that are investigated include hydrogen bromine electrolysis, municipal solid waste gasification, electro-farming (biomass gasifier and PEM fuel cell), wind/hydrogen hybrid system for remote sites, home electrolysis and alternate infrastructure options, renewable-based electrolysis to fuel PEM fuel cell vehicle fleet, and geothermal energy used to produce hydrogen. These systems are compared to conventional and benchmark technologies. Interim results and findings are presented. Independent analyses emphasize quality, integrity, objectivity, a long-term perspective, corporate memory, and the merging of technical, economic, operational, and programmatic expertise.

    CERN Document Server

    Howell, Kenneth B

    2001-01-01

    Fourier analysis is one of the most useful and widely employed sets of tools for the engineer, the scientist, and the applied mathematician. As such, students and practitioners in these disciplines need a practical and mathematically solid introduction to its principles. They need straightforward verifications of its results and formulas, and they need clear indications of the limitations of those results and formulas.Principles of Fourier Analysis furnishes all this and more. It provides a comprehensive overview of the mathematical theory of Fourier analysis, including the development of Fourier series, "classical" Fourier transforms, generalized Fourier transforms and analysis, and the discrete theory. Much of the author''s development is strikingly different from typical presentations. His approach to defining the classical Fourier transform results in a much cleaner, more coherent theory that leads naturally to a starting point for the generalized theory. He also introduces a new generalized theory based ...

  13. Longitudinal categorical data analysis

    CERN Document Server

    Sutradhar, Brajendra C

    2014-01-01

    This is the first book in longitudinal categorical data analysis with parametric correlation models developed based on dynamic relationships among repeated categorical responses. This book is a natural generalization of the longitudinal binary data analysis to the multinomial data setup with more than two categories. Thus, unlike the existing books on cross-sectional categorical data analysis using log linear models, this book uses multinomial probability models both in cross-sectional and longitudinal setups. A theoretical foundation is provided for the analysis of univariate multinomial responses, by developing models systematically for the cases with no covariates as well as categorical covariates, both in cross-sectional and longitudinal setups. In the longitudinal setup, both stationary and non-stationary covariates are considered. These models have also been extended to the bivariate multinomial setup along with suitable covariates. For the inferences, the book uses the generalized quasi-likelihood as w...

  15. Analysis in Banach spaces

    CERN Document Server

    Hytönen, Tuomas; Veraar, Mark; Weis, Lutz

    2016-01-01

    The present volume develops the theory of integration in Banach spaces, martingales and UMD spaces, and culminates in a treatment of the Hilbert transform, Littlewood-Paley theory and the vector-valued Mihlin multiplier theorem. Over the past fifteen years, motivated by regularity problems in evolution equations, there has been tremendous progress in the analysis of Banach space-valued functions and processes. The contents of this extensive and powerful toolbox have been mostly scattered around in research papers and lecture notes. Collecting this diverse body of material into a unified and accessible presentation fills a gap in the existing literature. The principal audience that we have in mind consists of researchers who need and use Analysis in Banach Spaces as a tool for studying problems in partial differential equations, harmonic analysis, and stochastic analysis. Self-contained and offering complete proofs, this work is accessible to graduate students and researchers with a background in functional an...

    CERN Document Server

    Denker, A; Rauschenberg, J; Röhrich, J; Strub, E

    2006-01-01

    Materials analysis with ion beams exploits the interaction of ions with the electrons and nuclei in the sample. Among the vast variety of possible analytical techniques available with ion beams we will restrain to ion beam analysis with ion beams in the energy range from one to several MeV per mass unit. It is possible to use either the back-scattered projectiles (RBS – Rutherford Back Scattering) or the recoiled atoms itself (ERDA – Elastic Recoil Detection Analysis) from the elastic scattering processes. These techniques allow the simultaneous and absolute determination of stoichiometry and depth profiles of the detected elements. The interaction of the ions with the electrons in the sample produces holes in the inner electronic shells of the sample atoms, which recombine and emit X-rays characteristic for the element in question. Particle Induced X-ray Emission (PIXE) has shown to be a fast technique for the analysis of elements with an atomic number above 11.

  11. Intelligent audio analysis

    CERN Document Server

    Schuller, Björn W

    2013-01-01

    This book provides the reader with the knowledge necessary for comprehension of the field of Intelligent Audio Analysis. It firstly introduces standard methods and discusses the typical Intelligent Audio Analysis chain going from audio data to audio features to audio recognition.  Further, an introduction to audio source separation, and enhancement and robustness are given.

    CERN Document Server

    Bruckstein, Alfred; Maragos, Petros; Wuhrer, Stefanie

    2016-01-01

    This book presents recent advances in the field of shape analysis. Written by experts in the fields of continuous-scale shape analysis, discrete shape analysis and sparsity, and numerical computing who hail from different communities, it provides a unique view of the topic from a broad range of perspectives. Over the last decade, it has become increasingly affordable to digitize shape information at high resolution. Yet analyzing and processing this data remains challenging because of the large amount of data involved, and because modern applications such as human-computer interaction require real-time processing. Meeting these challenges requires interdisciplinary approaches that combine concepts from a variety of research areas, including numerical computing, differential geometry, deformable shape modeling, sparse data representation, and machine learning. On the algorithmic side, many shape analysis tasks are modeled using partial differential equations, which can be solved using tools from the field of n...

    2005-08-01

    The Design-through-Analysis Realization Team (DART) is chartered with reducing the time Sandia analysts require to complete the engineering analysis process. The DART system analysis team studied the engineering analysis processes employed by analysts in Centers 9100 and 8700 at Sandia to identify opportunities for reducing overall design-through-analysis process time. The team created and implemented a rigorous analysis methodology based on a generic process flow model parameterized by information obtained from analysts. They also collected data from analysis department managers to quantify the problem type and complexity distribution throughout Sandia's analyst community. They then used this information to develop a community model, which enables a simple characterization of processes that span the analyst community. The results indicate that equal opportunity for reducing analysis process time is available both by reducing the ''once-through'' time required to complete a process step and by reducing the probability of backward iteration. In addition, reducing the rework fraction (i.e., improving the engineering efficiency of subsequent iterations) offers approximately 40% to 80% of the benefit of reducing the ''once-through'' time or iteration probability, depending upon the process step being considered. Further, the results indicate that geometry manipulation and meshing is the largest portion of an analyst's effort, especially for structural problems, and offers significant opportunity for overall time reduction. Iteration loops initiated late in the process are more costly than others because they increase ''inner loop'' iterations. Identifying and correcting problems as early as possible in the process offers significant opportunity for time savings.

    The ATLAS experiment accumulated more than 140 PB of data during the first run of the Large Hadron Collider (LHC) at CERN. The analysis of such an amount of data for the distributed physics community is a challenging task. The Distributed Analysis (DA) system of the ATLAS experiment is an established and stable component of the ATLAS distributed computing operations. About half a million user jobs are daily running on DA resources, submitted by more than 1500 ATLAS physicists. The reliability of the DA system during the first run of the LHC and the following shutdown period has been high thanks to the continuous automatic validation of the distributed analysis sites and the user support provided by a dedicated team of expert shifters. During the LHC shutdown, the ATLAS computing model has undergone several changes to improve the analysis workflows, including the re-design of the production system, a new analysis data format and event model, and the development of common reduction and analysis frameworks.

    NASA/NESSUS 6.2c is a general-purpose, probabilistic analysis program that computes probability of failure and probabilistic sensitivity measures of engineered systems. Because NASA/NESSUS uses highly computationally efficient and accurate analysis techniques, probabilistic solutions can be obtained even for extremely large and complex models. Once the probabilistic response is quantified, the results can be used to support risk-informed decisions regarding reliability for safety-critical and one-of-a-kind systems, as well as for maintaining a level of quality while reducing manufacturing costs for larger-quantity products. NASA/NESSUS has been successfully applied to a diverse range of problems in aerospace, gas turbine engines, biomechanics, pipelines, defense, weaponry, and infrastructure. This program combines state-of-the-art probabilistic algorithms with general-purpose structural analysis and lifting methods to compute the probabilistic response and reliability of engineered structures. Uncertainties in load, material properties, geometry, boundary conditions, and initial conditions can be simulated. The structural analysis methods include non-linear finite-element methods, heat-transfer analysis, polymer/ceramic matrix composite analysis, monolithic (conventional metallic) materials life-prediction methodologies, boundary element methods, and user-written subroutines. Several probabilistic algorithms are available such as the advanced mean value method and the adaptive importance sampling method. NASA/NESSUS 6.2c is structured in a modular format with 15 elements.

  16. A PROOF Analysis Framework

    CERN Document Server

    Gonzalez Caballero, Isidro

    2012-01-01

    The analysis of the complex LHC data usually follows a standard path that aims at minimizing not only the amount of data but also the number of observables used. After a number of steps of slimming and skimming the data, the remaining few terabytes of ROOT files hold a selection of the events and a flat structure for the variables needed that can be more easily inspected and traversed in the final stages of the analysis. PROOF arises at this point as an efficient mechanism to distribute the analysis load by taking advantage of all the cores in modern CPUs through PROOF Lite, or by using PROOF Cluster or PROOF on Demand tools to build dynamic PROOF cluster on computing facilities with spare CPUs. However using PROOF at the level required for a serious analysis introduces some difficulties that may scare new adopters. We have developed the PROOF Analysis Framework (PAF) to facilitate the development of new analysis by uniformly exposing the PROOF related configurations across technologies and by taking care of ...

  17. Navigating Critical Theory and Postmodernism: Social Justice and Therapist Power in Family Therapy.

    D'Arrigo-Patrick, Justine; Hoff, Chris; Knudson-Martin, Carmen; Tuttle, Amy

    2016-07-21

    The family therapy field encourages commitment to diversity and social justice, but offers varying ideas about how to attentively consider these issues. Critical informed models advocate activism, whereas postmodern informed models encourage multiple perspectives. It is often not clear how activism and an emphasis on multiple perspectives connect, engendering the sense that critical and postmodern practices may be disparate. To understand how therapists negotiate these perspectives in practice, this qualitative grounded theory analysis drew on interviews with 11 therapists, each known for their work from both critical and postmodern perspectives. We found that these therapists generally engage in a set of shared constructionist practices while also demonstrating two distinct forms of activism: activism through countering and activism through collaborating. Ultimately, decisions made about how to navigate critical and postmodern influences were connected to how therapists viewed ethics and the ways they were comfortable using their therapeutic power. The findings illustrate practice strategies through which therapists apply each approach.

    1994-01-01

    The objective of the Integrated Analysis Capability (IAC) system is to provide a highly effective, interactive analysis tool for the integrated design of large structures. With the goal of supporting the unique needs of engineering analysis groups concerned with interdisciplinary problems, IAC was developed to interface programs from the fields of structures, thermodynamics, controls, and system dynamics with an executive system and database to yield a highly efficient multi-disciplinary system. Special attention is given to user requirements such as data handling and on-line assistance with operational features, and the ability to add new modules of the user's choice at a future date. IAC contains an executive system, a data base, general utilities, interfaces to various engineering programs, and a framework for building interfaces to other programs. IAC has shown itself to be effective in automatic data transfer among analysis programs. IAC 2.5, designed to be compatible as far as possible with Level 1.5, contains a major upgrade in executive and database management system capabilities, and includes interfaces to enable thermal, structures, optics, and control interaction dynamics analysis. The IAC system architecture is modular in design. 1) The executive module contains an input command processor, an extensive data management system, and driver code to execute the application modules. 2) Technical modules provide standalone computational capability as well as support for various solution paths or coupled analyses. 3) Graphics and model generation interfaces are supplied for building and viewing models. Advanced graphics capabilities are provided within particular analysis modules such as INCA and NASTRAN. 4) Interface modules provide for the required data flow between IAC and other modules. 5) User modules can be arbitrary executable programs or JCL procedures with no pre-defined relationship to IAC. 6) Special purpose modules are included, such as MIMIC (Model

    2011-12-01

    Full Text Available Theme The situation analysis, as a separate component of the strategic planning, involves collecting and analysing relevant types of information on the components of the marketing environment and their evolution on the one hand and also on the organization’s resources and capabilities on the other. Objectives of the Research The main purpose of the study of the analysis techniques of the internal environment is to provide insight on those aspects that are of strategic importance to the organization. Literature Review The marketing environment consists of two distinct components, the internal environment that is made from specific variables within the organization and the external environment that is made from variables external to the organization. Although analysing the external environment is essential for corporate success, it is not enough unless it is backed by a detailed analysis of the internal environment of the organization. The internal environment includes all elements that are endogenous to the organization, which are influenced to a great extent and totally controlled by it. The study of the internal environment must answer all resource related questions, solve all resource management issues and represents the first step in drawing up the marketing strategy. Research Methodology The present paper accomplished a documentary study of the main techniques used for the analysis of the internal environment. Results The special literature emphasizes that the differences in performance from one organization to another is primarily dependant not on the differences between the fields of activity, but especially on the differences between the resources and capabilities and the ways these are capitalized on. The main methods of analysing the internal environment addressed in this paper are: the analysis of the organizational resources, the performance analysis, the value chain analysis and the functional analysis. Implications Basically such

    Citti, Giovanna; Pérez, Carlos; Sarti, Alessandro; Zhong, Xiao

    2015-01-01

    This book presents an expanded version of four series of lectures delivered by the authors at the CRM. Harmonic analysis, understood in a broad sense, has a very wide interplay with partial differential equations and in particular with the theory of quasiconformal mappings and its applications. Some areas in which real analysis has been extremely influential are PDE's and geometric analysis. Their foundations and subsequent developments made extensive use of the Calderón–Zygmund theory, especially the Lp inequalities for Calderón–Zygmund operators (Beurling transform and Riesz transform, among others) and the theory of Muckenhoupt weights.  The first chapter is an application of harmonic analysis and the Heisenberg group to understanding human vision, while the second and third chapters cover some of the main topics on linear and multilinear harmonic analysis. The last serves as a comprehensive introduction to a deep result from De Giorgi, Moser and Nash on the regularity of elliptic partial differen...

    Full Text Available Problem statement: The ukulele is a trendy instrument in the present day. It is a member of the guitar family of instruments which employs four nylon or gut strings or four courses of strings. However, a statistical analysis of the pitch of this instrument has not been conducted. To analysis pitch or fundamental frequency of its main cords should be performed in an appropriate way. This study brings about its effective sound synthesis which is an important issue in the future. Approach: An efficient technique for the analysis of the fundamental frequency (F0 of the human speech had been applied to the analysis of main cords of the ukulele. The autocorrelation-based technique was used with the signal waveform to extract the optimal period or pitch for the corresponding analyzed frame in time domain. Then the corresponding fundamental frequency was calculated in the frequency domain. Results: The 21 main cords were chosen in the study. It had been seen that the existing fundamental frequency values were varied from one to three values. The value was ranging from 65.42 Hz-329.93 Hz. Conclusion: By using the analysis technique of fundamental frequency of the human speech, the output frequencies of all main cords can be extracted. It can be empirically seen that they have their unique values from each others."

    2015-01-01

    Biosensors first appeared several decades ago to address the need for monitoring physiological parameters such as oxygen or glucose in biological fluids such as blood. More recently, a new wave of biosensors has emerged in order to provide more nuanced and granular information about the composition and function of living cells. Such biosensors exist at the confluence of technology and medicine and often strive to connect cell phenotype or function to physiological or pathophysiological processes. Our review aims to describe some of the key technological aspects of biosensors being developed for cell analysis. The technological aspects covered in our review include biorecognition elements used for biosensor construction, methods for integrating cells with biosensors, approaches to single-cell analysis, and the use of nanostructured biosensors for cell analysis. Our hope is that the spectrum of possibilities for cell analysis described in this review may pique the interest of biomedical scientists and engineers and may spur new collaborations in the area of using biosensors for cell analysis.

    2002-08-01

    A software application has been developed to aid law enforcement and government intelligence gathering organizations in the translation and analysis of foreign language documents with potential intelligence content. The Automated Document Analysis System (ADAS) provides the capability to search (data or text mine) documents in English and the most commonly encountered foreign languages, including Arabic. Hardcopy documents are scanned by a high-speed scanner and are optical character recognized (OCR). Documents obtained in an electronic format bypass the OCR and are copied directly to a working directory. For translation and analysis, the script and the language of the documents are first determined. If the document is not in English, the document is machine translated to English. The documents are searched for keywords and key features in either the native language or translated English. The user can quickly review the document to determine if it has any intelligence content and whether detailed, verbatim human translation is required. The documents and document content are cataloged for potential future analysis. The system allows non-linguists to evaluate foreign language documents and allows for the quick analysis of a large quantity of documents. All document processing can be performed manually or automatically on a single document or a batch of documents.

    2014-12-01

    The bedside measurement of continuous arterial pressure values from waveform analysis has been routinely available via indwelling arterial catheterization for >50 years. Invasive blood pressure monitoring has been utilized in critically ill patients, in both the operating room and critical care units, to facilitate rapid diagnoses of cardiovascular insufficiency and monitor response to treatments aimed at correcting abnormalities before the consequences of either hypo- or hypertension are seen. Minimally invasive techniques to estimate cardiac output (CO) have gained increased appeal. This has led to the increased interest in arterial waveform analysis to provide this important information, as it is measured continuously in many operating rooms and intensive care units. Arterial waveform analysis also allows for the calculation of many so-called derived parameters intrinsically created by this pulse pressure profile. These include estimates of left ventricular stroke volume (SV), CO, vascular resistance, and during positive-pressure breathing, SV variation, and pulse pressure variation. This article focuses on the principles of arterial waveform analysis and their determinants, components of the arterial system, and arterial pulse contour. It will also address the advantage of measuring real-time CO by the arterial waveform and the benefits to measuring SV variation. Arterial waveform analysis has gained a large interest in the overall assessment and management of the critically ill and those at a risk of hemodynamic deterioration.

  8. Professionalizing Intelligence Analysis

    2015-09-01

    Full Text Available This article examines the current state of professionalism in national security intelligence analysis in the U.S. Government. Since the introduction of major intelligence reforms directed by the Intelligence Reform and Terrorism Prevention Act (IRTPA in December, 2004, we have seen notable strides in many aspects of intelligence professionalization, including in analysis. But progress is halting, uneven, and by no means permanent. To consolidate its gains, and if it is to continue improving, the U.S. intelligence community (IC should commit itself to accomplishing a new program of further professionalization of analysis to ensure that it will develop an analytic cadre that is fully prepared to deal with the complexities of an emerging multipolar and highly dynamic world that the IC itself is forecasting. Some recent reforms in intelligence analysis can be assessed against established standards of more fully developed professions; these may well fall short of moving the IC closer to the more fully professionalized analytical capability required for producing the kind of analysis needed now by the United States.

    Electrophoresis and the following western blot analysis are indispensable to investigate biochemical changes in cells and tissues exposed to nanoparticles or nanomaterials. Proteins should be extracted from the cells and tissues using a proper method, especially when phosphorylated proteins are to be detected. It is important to select a good blocking agent and an appropriate pair of primary and peroxidase-tagged secondary antibodies to obtain good results in western blot analysis. One thing that may be specific to nanomaterials, and that you should keep in mind, is that some proteins may be adsorbed on the surface of particulate nanomaterials. In this chapter the whole process of western blot analysis, from sample preparation to quantitative measurement of target proteins, is described.

    2006-06-01

    The Velocity Interferometer System for Any Reflector (VISAR) is a widely used diagnostic at Sandia National Laboratories. Although the operating principles of the VISAR are well established, recently deployed systems (such as the fast push-pull and air delay VISAR) require more careful consideration, and many common assumptions about VISAR are coming into question. This report presents a comprehensive review of VISAR analysis to address these issues. Detailed treatment of several interferometer configurations is given to identify important aspects of the operation and characterization of VISAR systems. The calculation of velocity from interferometer measurements is also described. The goal is to derive the standard VISAR analysis relationships, indicate when these relationships are valid, and provide alternative methods when the standard analysis fails.

    This textbook is a thorough, accessible introduction to digital Fourier analysis for undergraduate students in the sciences. Beginning with the principles of sine/cosine decomposition, the reader walks through the principles of discrete Fourier analysis before reaching the cornerstone of signal processing: the Fast Fourier Transform. Saturated with clear, coherent illustrations, "Digital Fourier Analysis - Fundamentals" includes practice problems and thorough Appendices for the advanced reader. As a special feature, the book includes interactive applets (available online) that mirror the illustrations.  These user-friendly applets animate concepts interactively, allowing the user to experiment with the underlying mathematics. For example, a real sine signal can be treated as a sum of clockwise and counter-clockwise rotating vectors. The applet illustration included with the book animates the rotating vectors and the resulting sine signal. By changing parameters such as amplitude and frequency, the reader ca...

    Based on an honors course taught by the author at UC Berkeley, this introduction to undergraduate real analysis gives a different emphasis by stressing the importance of pictures and hard problems. Topics include: a natural construction of the real numbers, four-dimensional visualization, basic point-set topology, function spaces, multivariable calculus via differential forms (leading to a simple proof of the Brouwer Fixed Point Theorem), and a pictorial treatment of Lebesgue theory. Over 150 detailed illustrations elucidate abstract concepts and salient points in proofs. The exposition is informal and relaxed, with many helpful asides, examples, some jokes, and occasional comments from mathematicians, such as Littlewood, Dieudonné, and Osserman. This book thus succeeds in being more comprehensive, more comprehensible, and more enjoyable, than standard introductions to analysis. New to the second edition of Real Mathematical Analysis is a presentation of Lebesgue integration done almost entirely using the un...

    A new method called neutron signal transfer analysis has been developed for quantitative determination of hydrogenous distributions from neutron radiographic measurements. The technique is based on a model which describes the detector signal obtained in the measurement as a result of the action of three different mechanisms expressed by signal transfer functions. The explicit forms of the signal transfer functions are determined by Monte Carlo computer simulations and contain only the distribution as a variable. Therefore an unknown distribution can be determined from the detector signal by recursive iteration. This technique provides a simple and efficient tool for analysis of this type while also taking into account complex effects due to the energy dependency of neutron interaction and single and multiple scattering. Therefore this method provides an efficient tool for precise quantitative analysis using neutron radiography, as for example quantitative determination of moisture distributions in porous buil...

    Fuzzy data such as marks, scores, verbal evaluations, imprecise observations, experts' opinions and grey tone pictures, are quite common. In Fuzzy Data Analysis the authors collect their recent results providing the reader with ideas, approaches and methods for processing such data when looking for sub-structures in knowledge bases for an evaluation of functional relationship, e.g. in order to specify diagnostic or control systems. The modelling presented uses ideas from fuzzy set theory and the suggested methods solve problems usually tackled by data analysis if the data are real numbers. Fuzzy Data Analysis is self-contained and is addressed to mathematicians oriented towards applications and to practitioners in any field of application who have some background in mathematics and statistics.
