    Full Text Available Collection of data from animals for research purposes can negatively impact target or by-catch species if suitable animal ethics practices are not followed. This study aimed to assess the ethical requirements of peer-reviewed scientific journals that publish primary literature on fishes, and review the ethical considerations and animal care guidelines of national and international documents on the ethical treatment of animals for research, to provide an overview of the general ethical considerations for field research on fishes. A review of 250 peer-reviewed, ISI-rated journals publishing primary research on fishes revealed that nearly half (46% had no mention of ethics, treatment of animals or ethical requirements for publication in their author guidelines or publication policies. However, 18% of the journals reviewed identify a specific set of ethical guidelines to be followed before publishing research involving animals. Ethical considerations for investigators undertaking field research on fishes, common to most animal care policies, legislation and guiding documents, include adhering to relevant legislation, minimising sample sizes, reducing or mitigating pain and distress, employing the most appropriate and least invasive techniques and accurately reporting methods and findings. This information will provide potential investigators with a useful starting point for designing and conducting ethical field research. Application of ethical best practices in field sampling studies will improve the welfare of study animals and the conservation of rare and endangered species. Conservation implications: This article provides a list of ethical considerations for designing and conducting field research on fishes. By reviewing sampling techniques and processes that are frequently used in field research on fishes and by highlighting the potential negative impacts of these sampling techniques, this article is intended to assist researchers in planning

    Full Text Available The ability to computationally extract mentions of neuroanatomical regions from the literature would assist linking to other entities within and outside of an article. Examples include extracting reports of connectivity or region-specific gene expression. To facilitate text mining of neuroscience literature we have created a corpus of manually annotated brain region mentions. The corpus contains 1,377 abstracts with 18,242 brain region annotations. Interannotator agreement was evaluated for a subset of the documents, and was 90.7% and 96.7% for strict and lenient matching respectively. We observed a large vocabulary of over 6,000 unique brain region terms and 17,000 words. For automatic extraction of brain region mentions we evaluated simple dictionary methods and complex natural language processing techniques. The dictionary methods based on neuroanatomical lexicons recalled 36% of the mentions with 57% precision. The best performance was achieved using a conditional random field (CRF with a rich feature set. Features were based on morphological, lexical, syntactic and contextual information. The CRF recalled 76% of mentions at 81% precision, by counting partial matches recall and precision increase to 86% and 92% respectively. We suspect a large amount of error is due to coordinating conjunctions, previously unseen words and brain regions of less commonly studied organisms. We found context windows, lemmatization and abbreviation expansion to be the most informative techniques. The corpus is freely available at http://www.chibi.ubc.ca/WhiteText/.

  4. Information field for historical research

    Directory of Open Access Journals (Sweden)

    Sviatets, Yu. A.

    2017-09-01

    Full Text Available The article analyzes the main information collision of historical knowledge, which consists in physical inaccessibility of events and phenomena of the past as an object of historical science for a historian as an investigator. The aim of the research is to formulate and discuss a working hypothesis about the information field of historical science. The article provides an analytical background on the main ideas and approaches in the field of modern information field theory. The author carries out the projection of the main provisions of the information field theory on historical research. It is shown that the information field is a really existing information carrier that provides its acquisition, transportation, storage and visualization, as well as provides information and knowledge recorded in various forms, realizes cultural communications. One of the manifestations of such a culture is the sign systems, which determine certain contexts. Signs are characterized by polysemy. Despite artificial origin, semiotic reality is objective. Simultaneously, signs provide intellectual activity of people. Mental signs in the historical process of use by society acquire additional meanings, generating new symbols. Polysemy shapes the problem of epistemological uncertainty of two stages – identifying the problem and solving it. Historians as researchers resort to cognitive models, which, thanks to the translational function, ensure the transfer of information from the known to the unknown. One of the explanations of polysemy is the theory of conceptual integration, according to which the structures of the original mental spaces are projected onto a new, constructed, mental space – blend. This is the result of a personʼs intellectual ability to create new meanings on the basis of the available ones. Since signs and symbols are multi-valued, they form a multiplicity of retrospective scenarios of historical research at the stage of problem formulation

    2015-06-05

    Biomedical research has traditionally been conducted via surveys and the analysis of medical records. However, these resources are limited in their content, such that non-traditional domains (eg, online forums and social media) have an opportunity to supplement the view of an individual's health. The objective of this study was to develop a scalable framework to detect personal health status mentions on Twitter and assess the extent to which such information is disclosed. We collected more than 250 million tweets via the Twitter streaming API over a 2-month period in 2014. The corpus was filtered down to approximately 250,000 tweets, stratified across 34 high-impact health issues, based on guidance from the Medical Expenditure Panel Survey. We created a labeled corpus of several thousand tweets via a survey, administered over Amazon Mechanical Turk, that documents when terms correspond to mentions of personal health issues or an alternative (eg, a metaphor). We engineered a scalable classifier for personal health mentions via feature selection and assessed its potential over the health issues. We further investigated the utility of the tweets by determining the extent to which Twitter users disclose personal health status. Our investigation yielded several notable findings. First, we find that tweets from a small subset of the health issues can train a scalable classifier to detect health mentions. Specifically, training on 2000 tweets from four health issues (cancer, depression, hypertension, and leukemia) yielded a classifier with precision of 0.77 on all 34 health issues. Second, Twitter users disclosed personal health status for all health issues. Notably, personal health status was disclosed over 50% of the time for 11 out of 34 (33%) investigated health issues. Third, the disclosure rate was dependent on the health issue in a statistically significant manner (P<.001). For instance, more than 80% of the tweets about migraines (83/100) and allergies (85

    2014-11-01

    Full Text Available The World is in a continuous change at the level of all its components including entrepreneurship, the most dynamic element of the business activity. Another direction of change comes from technologies called “key enabling technologies” and represents a revolution in using raw materials and shapes the entire industrial process, obtaining competitive advantages. This paper tries to find a realistic answer to the question: is it possible to follow the global trend of technologies and to foster them in Romania? A realistic picture supplied by statistical data correlated with elements of the national plan of research and development offers a more theoretical approach since practical examples are almost non-existent, but the potential to apply these ideas through entrepreneurship is promising. Meeting recommended goals from this paper, through cooperation between private companies, state and academies, creativity and innovation will boost new ideas for a better life in a healthier Romania.

  10. Reducing the ecological impact of field research.

    Bezanson, Michelle; Stowe, Rochelle; Watts, Sean M

    2013-01-01

    Researchers and students at biological field stations, especially in remote areas, are subject to leaving "footprints," as we conduct research, work, and live in sensitive ecosystems. These footprints include travel, personal trash and waste, and field equipment (e.g. flagging, tree markers, plot markers, trail markers, monitoring devices, etc.). In this commentary, we argue that the field of primatology's commitment to minimum impact research should be more explicitly and visibly integrated into our ethical protocols with regard to field research and instruction in sensitive environments. We review current ethical codes and potential solutions to reducing our "researcher footprints" while conducting fieldwork. Using Costa Rica as an example, we address how sustainable fieldwork differs among varying cultural contexts and argue that researchers should be made responsible and accountable for how our presence, research, and teaching might impact the environment. We conclude by recommending a set of guidelines to be added to ethical protocols regarding research design, station policies, and the conduct of research and teaching in the field. © 2012 Wiley Periodicals, Inc.

    Kernan, K T; Sabsay, S

    1987-01-01

    Referential first mentions in narrative reports of a short film by 40 mildly mentally retarded adults and 20 nonretarded adults were compared. The mentally retarded sample included equal numbers of male and female, and black and white speakers. The mentally retarded speakers made significantly fewer first mentions and significantly more errors in the form of the first mentions than did nonretarded speakers. A pattern of better performance by black males than by other mentally retarded speakers was found. It is suggested that task difficulty and incomplete mastery of the use of definite and indefinite forms for encoding old and new information, rather than some global type of egocentrism, accounted for the poorer performance by mentally retarded speakers.

    Full Text Available In complex stimuli, there are many different possible ways to refer to a specified target. Previousstudies have shown that when people are faced with such a task, the content of their referringexpression reflects visual properties such as size, salience and clutter. Here, we extend thesefindings and present evidence that (i the influence of visual perception on sentence constructiongoes beyond content selection and in part determines the order in which different objects arementioned and (ii order of mention influences comprehension. Study 1 (a corpus study ofreference productions shows that when a speaker uses a relational description to mention asalient object, that object is treated as being in the common ground and is more likely to bementioned first. Study 2 (a visual search study asks participants to listen to referring expressionsand find the specified target; in keeping with the above result, we find that search for easy-to-findtargets is faster when the target is mentioned first, while search for harder-to-find targets isfacilitated by mentioning the target later, after a landmark in a relational description. Our findingsshow that seemingly low-level and disparate mental modules like perception and sentenceplanning interact at a high level and in task-dependent ways.

    2005-12-01

    From studying snow geese on the North Slope of Alaska to sediment coring aboard the U.S. Coast Guard Cutter Healy in the Arctic Ocean, K-12 teachers embark on scientific expeditions as part of a program that strives to make science in the Arctic a "virtual" reality. In the past two years, seventeen K-12 teachers have participated in Teachers and Researchers Exploring and Collaborating (TREC), a program that pairs teachers with researchers to improve science education through arctic field experiences. TREC builds on the scientific and cultural opportunities of the Arctic, linking research and education through topics that naturally engage students and the wider public. TREC includes expeditions as diverse as studying plants at Toolik Field Station, a research facility located 150 miles above the Arctic Circle; climate change studies in Norway's Svalbard archipelago; studying rivers in Siberia; or a trans-arctic expedition aboard the USCGC Healy collecting an integrated geophysical data set. Funded by the National Science Foundation Office of Polar Programs, TREC offers educators experiences in scientific inquiry while encouraging the public and students to become active participants in the scientific inquiry by engaging them virtually in arctic research. TREC uses online outreach elements to convey the research experience to a broad audience. While in remote field locations, teachers and researchers interact with students and the public through online seminars and live calls from the field, online journals with accompanying photos, and online bulletin boards. Since the program's inception in 2004, numerous visitors have posted questions or interacted with teachers, researchers, and students through the TREC website (http://www.arcus.org/trec). TREC teachers are required to transfer their experience of research and current science into their classroom through the development of relevant activities and resources. Teachers and researchers are encouraged to participate

  15. How Do Trend Researchers Conduct Research? The Production of Knowledge in a Controversial Field

    Michaela Pfadenhauer

    2004-05-01

    Full Text Available The planned research project described in this article focuses on the methods of trend research—not only in a narrow literal sense of techniques of data collection and data evaluation but also in a broader understanding of the logic of knowledge production in this controversial field. Initially trend research can be appointed between market research on the one hand and futurology on the other hand. Criticism regarding trend research as well as its innovative potential is also mentioned. Following the recent studies, trend research is conceived as application-oriented research in a broad sense. As far as the methodology is concerned, the proposed study promises to be an empirically-founded contribution by integrating analysis from sources such as explorative and focused conversations, observations and expert interviews. The study uses the example of trend research and asks the question how research is actually "done" and if it is application oriented or not. URN: urn:nbn:de:0114-fqs0402366

    2018-01-01

    Micro-blogging systems have become one of the most important ways for information sharing. Network structure and users' interactions such as forwarding behaviors have aroused considerable research attention, while mention, as a key feature in micro-blogging platforms which can improve the visibility of a message and direct it to a particular user beyond the underlying social structure, is seldom studied in previous works. In this paper, we empirically study the mention effect in information diffusion, using the dataset from a population-scale social media website. We find that users with high number of followers would receive much more mentions than others. We further investigate the effect of mention in information diffusion by examining the response probability with respect to the number of mentions in a message and observe a saturation at around 5 mentions. Furthermore, we find that the response probability is the highest when a reciprocal followship exists between users, and one is more likely to receive a target user's response if they have similar social status. To illustrate these findings, we propose the response prediction task and formulate it as a binary classification problem. Extensive evaluation demonstrates the effectiveness of discovered factors. Our results have consequences for the understanding of human dynamics on the social network, and potential implications for viral marketing and public opinion monitoring.

    1987-02-01

    The goal of the study is to give an overview of the whole diversified research field of fire technology and its problems. For this reason the research subjects have been grouped so that the responsibilities of different authorities, the legislation and specifications, various fields of technology, areas of industry, and groups of products could all be found as clearly as possible. The field has been divided into nine sub-areas. They are: general grounds, fire physics and chemistry, structural fire prevention, textiles and furnishings, devices for heating and other use, detection, fire fighting and rescue, quality control, and special problems. The sub-areas have been divided into 34 main subjects and these, excluding those of special problems, further into as many as 117 subject groups. Characteristics and problems of the sub-areas and the main subjects have been described. The subject groups have been characterized by key words and concepts which outline the projects. No concrete research projects and programs have, however, been directly suggested because their extent and contents depend essentially on financing and other available resources.

    The Quran is regarded as both the spiritual and behavioral guidance for all Muslims. This narrative study was designed at examining relevant health-promoting verses in the Quran and to identify the chapters and verses where keywords and phrases are mentioned relevant to health promotion and behavior. Twenty-eight verses were identified, with a focus on diet and nutrition, personal hygiene, alcohol abstention, and the importance of a healthy lifestyle. These results suggest that the Quran could serve as an influential medium for culturally competent public health practitioners in diverse populations, particularly in Muslim communities, for improving and maintaining healthy behaviors.

    'Kei'-supercomputer is planned to start its full-scale operation in about one year and a half. With this, High Performance Computing (HPC) is most likely to contribute not only to further progress in basic and applied sciences, but also to bringing about innovations in various fields of industries. It is expected to substantially shorten design time, drastically improve performance and/or liability of various industrial products, and greatly enhance safety of large-scale power plants. In this particle, six research themes, which are currently being prepared in this strategic research field, 'industrial innovations' so as to use 'Kei'-supercomputer as soon as it starts operations, will be briefly described regarding their specific goals and break-through that they are expected to bring about in industries. It is also explained how we have determined these themes. We are also planning several measures in order to promote widespread use of HPC including 'Kei'-supercomputer in industries, which will also be elaborated in this article. (author)

    The increase in the incidence of HIV/AIDS among minorities in the United States and in certain developing nations has prompted new intervention priorities, stressing the adaptation of efficacious interventions for diverse and marginalized groups. The experiences of Florida International University's AIDS Prevention Program in translating HIV primary and secondary prevention interventions among these multicultural populations provide insight into the process of cultural adaptations and address the new scientific emphasis on ecological validity. An iterative process involving forward and backward translation, a cultural linguistic committee, focus group discussions, documentation of project procedures, and consultations with other researchers in the field was used to modify interventions. This article presents strategies used to ensure fidelity in implementing the efficacious core components of evidence-based interventions for reducing HIV transmission and drug use behaviors and the challenges posed by making cultural adaptation for participants with low literacy. This experience demonstrates the importance of integrating culturally relevant material in the translation process with intense focus on language and nuance. The process must ensure that the level of intervention is appropriate for the educational level of participants. Furthermore, the rights of participants must be protected during consenting procedures by instituting policies that recognize the socioeconomic, educational, and systemic pressures to participate in research.

    Guerin De Montgareuil, P.

    1964-01-01

    This report presents a survey of the most important work in the field of nuclear agronomy carried out in France since the second international conference, ranging from pure research to the most direct application. As the programmes develop, so to an ever decreasing degree does this differentiation cover the distinction made in the report between the biological radiations effects and the other uses of nuclear techniques. Thus research on agricultural radio-genetics is carried on in two directions: from the theoretical and methodological angle, with comparative studies of the action of various types of radiation, the influence of dose rate and temperature, the action of chemical mutation agents, the production of chimera by gamma irradiation; and on the practical side, leading to the creation of new, hardier or earlier varieties (rice, millet, ground-nuts). Problems of pest destruction (eradication) and the preservation of foodstuffs by irradiation are also tackled by widely varied means and for totally different purposes. One operation consisting of a simple irradiation (moist seeds, potatoes...) will sometimes be associated with original studies of a biochemical or microbiological nature (for example: decomposition of starch, glucide metabolism of irradiated tubers, radiation resistance of yeasts). The nuclear technique side is represented mainly by radioisotopes (carbon 14, phosphorus 32, sulphur 35, calcium 45, potassium 42, copper 64, gold 198) and stable isotopes analysed by mass spectrometer (nitrogen 15, oxygen 18) or by neutron activation (boron 10). The studies mentioned refer to problems on different levels concerning plant physiology, agrology, agricultural entomology and zootechny. Results obtained from measurements of the humidity (neutron thermalization) and density (gamma diffusion) of a soil are also given. Numerous organisations take part in these various research programmes, each according to its speciality: cooperative private enterprise

    Tagging gene and gene product mentions in scientific text is an important initial step of literature mining. In this article, we describe in detail our gene mention tagger participated in BioCreative 2 challenge and analyze what contributes to its good performance. Our tagger is based on the conditional random fields model (CRF), the most prevailing method for the gene mention tagging task in BioCreative 2. Our tagger is interesting because it accomplished the highest F-scores among CRF-based methods and second over all. Moreover, we obtained our results by mostly applying open source packages, making it easy to duplicate our results. We first describe in detail how we developed our CRF-based tagger. We designed a very high dimensional feature set that includes most of information that may be relevant. We trained bi-directional CRF models with the same set of features, one applies forward parsing and the other backward, and integrated two models based on the output scores and dictionary filtering. One of the most prominent factors that contributes to the good performance of our tagger is the integration of an additional backward parsing model. However, from the definition of CRF, it appears that a CRF model is symmetric and bi-directional parsing models will produce the same results. We show that due to different feature settings, a CRF model can be asymmetric and the feature setting for our tagger in BioCreative 2 not only produces different results but also gives backward parsing models slight but constant advantage over forward parsing model. To fully explore the potential of integrating bi-directional parsing models, we applied different asymmetric feature settings to generate many bi-directional parsing models and integrate them based on the output scores. Experimental results show that this integrated model can achieve even higher F-score solely based on the training corpus for gene mention tagging. Data sets, programs and an on-line service of our gene

    Full Text Available A new theoretical discipline, narratology, deals with the problems of organizing text at a narrative level. The beginnings of narratology are related to the eighth issue of the journal "Communication" (1966, devoted to research stories. Mieke Bal wrote the first book that contains the word "Narratology" in its title (1979. The beginnings of narratological research can be found in Aristotle's Poetics, where he dealt with the problem of organizing the narration of a text with the action and the characters, and with the qualification of the elements of narrative text. The paper highlights the ontology of contemporary narratological landscape through semiotic research.

    2014-03-01

    Full Text Available Objective – This study examined the effects that mentioning the survey incentive prize in the subject line of a reminder email had on the response rate and data quality. To date, manipulation of the subject line, specifically in terms of mentioning the incentive prize, has received limited attention in the survey design literature. Methods – The delivery of the survey invitation is discussed in terms of the timing of the launch and reminder emails. Particular emphasis is given to the design of the email subject line and justification of the format. Weekly response rates from four LibQUAL+TM surveys were compared. In addition, weekly responses for one year were analyzed using SPSS to investigate if there were any between means differences in terms of three elements of data quality. The three elements were: length of time it took to complete the survey, the number of core questions with an N/A response, and the number of illogical responses where minimum scores were higher than desired. Results – The response rates for the second week were grouped together based on the presence or absence of the subject line manipulation. There was a significant difference between these means (4.75%, p 0.033. There was no statistical difference in regards to the measures of data quality as determined by a one-way ANOVA test. Conclusions – Reminding survey participants with an email that mentions the incentive prize in the subject line appears to increase response rates with no deleterious effects on data quality. The results of this investigation are encouraging, and those running the LibQUAL+TM survey in their universities should consider implementing this method to increase response rates. Further research to replicate these findings in other contexts and using an experimental design would be beneficial.

  17. Research in the fields of medicine in Slovenia – research potential, funding, and publications

    2012-09-01

    Conclusions: The size of the human research potential in the fields of medicine in Slovenia is modest. The majority of researchers are also engaged in medical practice and education. Consequently, funds from public sources for research per researcher are low. Research fields of medicine primarly require an increase in human research resources, which can then provide a basis for a rise in funding and the impact of its research results becoming comparable to the EU and world averages.

  18. Research collaboration in groups and networks: differences across academic fields.

    Science.gov (United States)

    Kyvik, Svein; Reymert, Ingvild

    2017-01-01

    The purpose of this paper is to give a macro-picture of collaboration in research groups and networks across all academic fields in Norwegian research universities, and to examine the relative importance of membership in groups and networks for individual publication output. To our knowledge, this is a new approach, which may provide valuable information on collaborative patterns in a particular national system, but of clear relevance to other national university systems. At the system level, conducting research in groups and networks are equally important, but there are large differences between academic fields. The research group is clearly most important in the field of medicine and health, while undertaking research in an international network is most important in the natural sciences. Membership in a research group and active participation in international networks are likely to enhance publication productivity and the quality of research.

    2014-11-01

    Full Text Available This research aims to explore correlations between consumer-generated social media activity and the level of sales of German brands from the fast moving consumer goods industry. In particular, the objective was to examine whether there is a correlation between the number of brand mentions in social media and the sales of these products. The results indicate that the number of brand mentions and sales correlate positively in relation to products from the food and beverages category while this is not the case with respect to the non-food product category. Hence, marketers need to promote consumer-generated social media activity particularly for food and beverages.

  15. Entering the Field: Decisions of an Early Career Researcher

    Directory of Open Access Journals (Sweden)

    Sajeel Ahmed

    2016-12-01

    Full Text Available Classic grounded theory methodology is a much-debated topic in research, especially when novice researchers are selecting classic grounded theory for their research or theses. There is a constant need to justify and defend certain processes of grounded theory, which often challenge other research methods. As a novice researcher, I have often found myself juggling between the need to follow specific procedures and regulations of the university while opting to support the views of Glaser and the application of classic grounded theory for my research. To tackle such difficulties, specific decisions were used to support and justify key choices that favoured classic grounded theory and the requirements of the research institute and my research process. This article provides a reflection on the decisions taken at different stages of the research process to help readers make informed decisions before entering the field.

  16. Microtask crowdsourcing for disease mention annotation in PubMed abstracts.

    Science.gov (United States)

    Good, Benjamin M; Nanis, Max; Wu, Chunlei; Su, Andrew I

    2015-01-01

    Identifying concepts and relationships in biomedical text enables knowledge to be applied in computational analyses. Many biological natural language processing (BioNLP) projects attempt to address this challenge, but the state of the art still leaves much room for improvement. Progress in BioNLP research depends on large, annotated corpora for evaluating information extraction systems and training machine learning models. Traditionally, such corpora are created by small numbers of expert annotators often working over extended periods of time. Recent studies have shown that workers on microtask crowdsourcing platforms such as Amazon's Mechanical Turk (AMT) can, in aggregate, generate high-quality annotations of biomedical text. Here, we investigated the use of the AMT in capturing disease mentions in PubMed abstracts. We used the NCBI Disease corpus as a gold standard for refining and benchmarking our crowdsourcing protocol. After several iterations, we arrived at a protocol that reproduced the annotations of the 593 documents in the 'training set' of this gold standard with an overall F measure of 0.872 (precision 0.862, recall 0.883). The output can also be tuned to optimize for precision (max = 0.984 when recall = 0.269) or recall (max = 0.980 when precision = 0.436). Each document was completed by 15 workers, and their annotations were merged based on a simple voting method. In total 145 workers combined to complete all 593 documents in the span of 9 days at a cost of $.066 per abstract per worker. The quality of the annotations, as judged with the F measure, increases with the number of workers assigned to each task; however minimal performance gains were observed beyond 8 workers per task. These results add further evidence that microtask crowdsourcing can be a valuable tool for generating well-annotated corpora in BioNLP. Data produced for this analysis are available at http://figshare.com/articles/Disease_Mention_Annotation_with_Mechanical_Turk/1126402.

    2016-03-01

    Poor reporting of research may limit critical appraisal and reproducibility, whereas adherence to reporting guidelines (RG) can guarantee completeness and transparency. We aimed to determine the explicit citing of RGs (CONSORT, PRISMA, STROBE) in urogynecology articles in 2013, the requirements of relevant journals and a potential difference between urogynecology and general gynecology journals. All urogynecologic articles published between January and December 2013 in the journals NAU, IUJ, FPMRS, GREEN, AJOG, and BJOG were included. Issues were searched for systematic reviews, RCTs, cohort studies, case-control studies and cross-sectional studies. Each electronic article was searched for the term PRISMA, CONSORT, or STROBE according to the study design. Instructions to Authors of the six journals were screened for requirement of using RGs. We included 296 articles (243 observational studies, 40 RCTs, and 13 systematic reviews). The use of PRISMA guidelines was explicitly declared in 54% of systematic reviews, CONSORT guidelines were referenced in 25% of RCTs and STROBE in 1.2% of observational studies. The use of CONSORT is required by all journals except FPMRS. PRISMA and STROBE are only compulsory in the journals GREEN, AJOG, and BJOG. The overall rate of explicit mentioning of RGs comparing urogynecology and general gynecology journals was 6.7% versus 7.1%, respectively. The explicit mentioning of RGs was on a relatively low level. A slightly higher adherence was recognized among general gynecology journals compared to urogynecology journals. Stronger efforts should be taken to further promote the use of RGs in urogynecology. © 2015 Wiley Periodicals, Inc.

    2016-07-01

    This special session forms part of a larger program aimed at the multiplication and integration of methodological approaches in the research evaluation and innovation policy field. The session builds on previous initiatives by Gemma Derrick and colleagues at CWTS, INGENIO, the Rathenau Instituut and SPRU, exploring the advantages of qualitative methodological tools at the STI/ENID conference in Lugano, and an international workshop in London in October 2015. The program is highly topical: the research evaluation field is currently reconsidering its methodological foundations in light of new research questions arising from policy initiatives regarding a) the move toward open science; b) a reconceptualization of research excellence to include societal relevance; c) diversification of academic careers, and d) the search for indicators showcasing responsible research behavior and innovation. This new special session at STI2016 will advance and broaden the scope of previous initiatives by building bridges between cutting edge research involving quantitative, qualitative, and mixed methodological research designs. Bringing together leading experts and promising researchers with distinctive methodological skill-sets, the session will demonstrate the advantages of cross-fertilization between ‘core’ and ‘peripheral’ methodological approaches for the research evaluation and science indicators field.

    Institute of Cancer Research (ICR) mice have been widely used in various research fields including toxicology, oncology, pharmacology, and pharmaceutical product safety testing for decades. However, annual tendency of research papers involving ICR mice in various biomedical fields has not been previously analyzed. In this study, we examined the numbers of papers that used ICR mice as experimental animals in the social science, natural science, engineering, medicine-pharmacy, marine agriculture-fishery, and art-kinesiology fields by analyzing big data. Numbers of ICR mouse-used papers gradually increased from 1961 to 2014, but small decreases were observed in 2015 and 2016. The largest number of ICR-used papers were published in the medicine-pharmacy field, followed by natural science and art-kinesiology fields. There were no ICR mouse-used papers in other fields. Furthermore, ICR mice have been widely employed in cell biology studies within the natural science field as well as in biochemistry and pathology in the medicine-pharmacy field. Few ICR mouse-used papers were published in exercise biochemistry and exercise nutrition in the art-kinesiology field. Regardless in most fields, the total numbers of published papers involving ICR mice were higher in 2014 than in other years, although the numbers in some fields including dentistry, veterinary science, and dermatology were high in 2016. Taken together, the present study shows that various ICR stocks, including Korl:ICR mice, are widely employed as experimental animals in various biomedical research fields.

    2015-04-01

    Several studies have demonstrated that undergraduate students benefit from research experiences. Benefits of undergraduate research include 1) personal and intellectual development, 2) more and closer contact with faculty, 3) the use of active learning techniques, 4) creation of high expectations, 5) development of creative and problem-solving skills, 6) greater independence and intrinsic motivation to learn, and 7) exposure to practical skills. The scientific discipline also benefits, as studies have shown that undergraduates who engage in research experiences are more likely to remain science majors and finish their degree program (Lopatto, 2007). Research experiences come as close as possible to allowing undergraduates to experience what it is like to be an academic or research member of their profession working to advance their discipline. Soils form in the field, therefore, field experiences are very important in developing a complete and holistic understanding of soil science. Combining undergraduate research with field experiences can provide extremely beneficial outcomes to the undergraduate student, including increased understanding of and appreciation for detailed descriptions and data analysis as well as an enhanced ability to see how various parts of their undergraduate education come together to understand a complex problem. The experiences of the authors in working with undergraduate students on field-based research projects will be discussed, along with examples of some of the undergraduate research projects that have been undertaken. In addition, student impressions of their research experiences will be presented. Reference Lopatto, D. 2007. Undergraduate research experiences support science career decisions and active learning.

Mainly based on the most recen t results, this review aims to identify the main research and breeding targets for these two crops, as seen through publications, with an attempt to suggest what are opportunities and challenges in these research fields. Growing a healthy and yielding crop remains the key driver for agronomic production. However sustainability and environmental profiles of the cultivar are now entering the field of play: The sustainability concern invested the field of resistance to diseases. Nitrogen use efficiency became an important target for Brassica napus, and crop resilience toward drought stresses is the way chosen in Helianthus annuus breeding for yield improvement. Significant advances are underway for quality traits, but the uncertainty on nutritional and industrial demand may explain why the product diversification remains low.

    Agni (digestive fire), Prakruti (constitution), Dhatusarata (tissue excellence), Dosha (bio–energies) are the specialties of Ayurveda on which diagnosis, treatment and research are based. The description of Dhatusarata (tissue excellence) has been given under Dashavidha Pariksha (tenfold examination) in Charak Samhita, Viman Sthana, 8th chapter. Some qualities, which are mentioned in Dhatusarata are difficult to assess, e.g. Sukha, Aishwarya, Upabhoga, Bala, etc., There is a need to develop some quantitative parameters to measure these qualities according to tissue excellence i.e. Dhatusarata. By assessing Dhatu Sarata, one can judge the true strength of a particular Dhatu but only the ability or strength is not enough to get success; the liking or interest is also essential to achieve success. The purpose of this study is to elaborate the concept of Dhatusarata and reveal different aspects of Sukha according to the quality of that particular Dhatu in context of vocational guidance. It will help to establish interrelationship between Dhatusarata and vocational guidance. It will be assessed whether this Sukha quality is merely happiness or having different shades according to the excellence of Dhatus and whether this study is useful in guiding the person to choose appropriate profession, which will be according to his liking and ability. It has been concluded that shades of Sukha quality varies with particular Dhatusaras, which may be helpful in guiding a suitable profession to an individual which will be according to his ability and liking i.e. Sukha for intimate success.

    Research in the field of primary care has dramatically increased in France in recent years, especially since 2013 with the introduction of primary care as a thematic priority for research proposals launched by the Ministry of Health (Direction générale de l'offre de soins). The RECaP (Research in Clinical Epidemiology and Public Health) network is a French research network supported by Inserm, which recently implemented a specific working group focusing on research in primary care, based on a multidisciplinary approach. Researchers from different specialties participate in this group. The first aim of the group was to reach a common definition of the perimeter and of the panel of healthcare professionals and structures potentially involved in the field of primary care. For this purpose, a selection of different data sets of sources defining primary care was analyzed by the group, each participant collecting a set of sources, from which a synthesis was made and discussed. A definition of primary care at different levels (international, European and French) was summarized. A special attention was given to the French context in order to adapt the perimeter to the characteristics of the French healthcare system, notably by illustrating the different key elements of the definition with the inclusion of primary care actors and the type of practice premises. In conclusion, this work illustrates the diversity of primary care in France and the potential offered for research purposes. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

  15. Women's mental health research: the emergence of a biomedical field.

    Science.gov (United States)

    Blehar, Mary C

    2006-01-01

    This review surveys the field of women's mental health, with particular emphasis on its evolution into a distinct area of biomedical research. The field employs a biomedical disease model but it also emphasizes social and cultural influences on health outcomes. In recent years, its scope has expanded beyond studies of disorders occurring in women at times of reproductive transitions and it now encompasses a broader study of sex and gender differences. Historical and conceptual influences on the field are discussed. The review also surveys gender differences in the prevalence and clinical manifestations of mental disorders. Epidemiological findings have provided a rich resource for theory development, but without research tools to test theories adequately, findings of gender differences have begged the question of their biological, social, and cultural origins. Clinical depression is used to exemplify the usefulness of a sex/gender perspective in understanding mental illness; and major theories proposed to account for gender differences are critically evaluated. The National Institutes of Health (NIH) is the primary federal funding source for biomedical women's mental health research. The review surveys areas of emphasis in women's mental health research at the NIH as well as some collaborative activities that represent efforts to translate research findings into the public health and services arenas. As new analytic methods become available, it is anticipated that a more fundamental understanding of the biological and behavioral mechanisms underlying sex and gender differences in mental illness will emerge. Nonetheless, it is also likely that integration of findings predicated on different conceptual models of the nature and causes of mental illness will remain a challenge. These issues are discussed with reference to their impact on the field of women's mental health research.

    The purpose of this paper is to comprehensively explore scientific research profiles in the field of emerging nano-energy during 1991-2012 based on bibliometrics and social network analysis. We investigate the growth pattern of research output, and then carry out across countries/regions comparisons on research performances. Furthermore, we examine scientific collaboration across countries/regions by analyzing collaborative intensity and networks in 3- to 4-year intervals. Results indicate with an impressively exponential growth pattern of nano-energy articles, the world share of scientific "giants," such as the USA, Germany, England, France and Japan, display decreasing research trends, especially in the USA. Emerging economies, including China, South Korea and India, exhibit a rise in terms of the world share, illustrating strong development momentum of these countries in nano-energy research. Strikingly, China displays a remarkable rise in scientific influence rivaling Germany, Japan, France, and England in the last few years. Finally, the scientific collaborative network in nano-energy research has expanded steadily. Although the USA and several major European countries play significantly roles on scientific collaboration, China and South Korea exert great influence on scientific collaboration in recent years. The findings imply that emerging economies can earn competitive advantages in some emerging fields by properly engaging a catch-up strategy.

Several authoritative reviews of this subject have been published. currently, the major uncertainty and the major research effort is directed to the issue of these fields and cancer. Therefore, this review will be limited to examining the evidence relating prolonged power-frequency electric and magnetic field exposure to cancer in human populations. This paper reports that the CIGRE expert Group has assessed the research literature in the following areas: epidemiological evidence, animal studies, cellular effects, knowledge of mechanisms

  1. An Organizational Perspective to the Creation of the Research Field.

    Talamo, Alessandra; Mellini, Barbara; Camilli, Marco; Ventura, Stefano; Di Lucchio, Loredana

    2016-09-01

    The aim of the paper is to contribute to the definition and analysis of the "access to the field" (Feldman et al. 2003) through an inter-organizational perspective. The paper discusses a case study on the access of a researcher to a hospital department where both organizations and actors are shown as actively constructing the research site. Both researcher and participants are described in terms of work organizations originally engaged in parallel systems of activity. Dynamics of negotiation "tied" the different actors' activities in a new activity system where researcher and participants concur to the effectiveness of both organizations (i.e., the research and the hospital ward). An Activity Theory perspective (Leont'ev 1978) is used with the aim of focusing the analysis on the activities in charge to the different actors. The approach adopted introduces the idea that, from the outset, research is made possible by a process of co-construction that works through the development of a completely new and shared work space arising around the encounter between researchers and participants. It is the balance between improvised actions and the co-creation of "boundary objects" (Star and Griesemer 1989), which makes interlacement possible between the two activity systems. The concept of "knotworking" (Engeström 2007a) is adopted to interpret specific actions by both organizations and actors intended to build a knot of activities whereby the new research system takes place.

    1992-01-01

    As part of the Yucca Mountain Site Characterization Project, a field research program has been developed to refine and validate models for flow and transport through unsaturated fractured rock. Validation of these models within the range of their application for performance assessment requires a more sophisticated understanding of the processes that govern flow and transport within fractured porous media than currently exists. In particular, our research is prioritized according to understanding and modeling processes that, if not accurately incorporated into performance assessment models, would adversely impact the project's ability to evaluate repository performance. For this reason, we have oriented our field program toward enhancing our understanding of scaling processes as they relate to effective media property modeling, as well as to the conceptual modeling of complex flow and transport phenomena

    Full Text Available Thanks to the development of the concept of metadiscourse, it is now widely acknowledged that academic/scientific writing is not only concerned with communicating purely propositional meanings: what is communicated through academic/scientific communication is seen to be intertwined with the negotiation of social and interpersonal meanings. While a large number of so called metadiscoursal resources contribute to the simultaneous negotiation of propositional and interpersonal meanings, the present study aimed at investigating the functions self-mention forms can fulfill in academic/scientific communication. Two of Stephen Hawking's scientific books were selected as the corpus of the research, and based on Tang and John's (1999 model, the constructed corpus was analyzed in terms of the functions self-mention forms can fulfill in academic/scientific writing. The findings revealed that from among the different roles identified by Tang and John, the representative role constituted the most frequent self-mention function in the corpus. The remarkably heavy presence of representative role in Hawking's scientific prose was interpreted as a further evidence for the claim that scientists are more likely to persuade readers of their ideas if they frame their messages in ways which appeal to appropriate community-recognized relationships.

    The Computer-Based Procedure (CBP) research effort is a part of the Light-Water Reactor Sustainability (LWRS) Program, which provides the technical foundations for licensing and managing the long-term, safe, and economical operation of current nuclear power plants. One of the primary missions of the LWRS program is to help the U.S. nuclear industry adopt new technologies and engineering solutions that facilitate the continued safe operation of the plants and extension of the current operating licenses. One area that could yield tremendous savings in increased efficiency and safety is in improving procedure use. A CBP provides the opportunity to incorporate context-driven job aids, such as drawings, photos, and just-in-time training. The presentation of information in CBPs can be much more flexible and tailored to the task, actual plant condition, and operation mode. The dynamic presentation of the procedure will guide the user down the path of relevant steps, thus minimizing time spent by the field worker to evaluate plant conditions and decisions related to the applicability of each step. This dynamic presentation of the procedure also minimizes the risk of conducting steps out of order and/or incorrectly assessed applicability of steps. This report provides a summary of the main research activities conducted in the Computer-Based Procedures for Field Workers effort since 2012. The main focus of the report is on the research activities conducted in fiscal year 2016. The activities discussed are the Nuclear Electronic Work Packages - Enterprise Requirements initiative, the development of a design guidance for CBPs (which compiles all insights gained through the years of CBP research), the facilitation of vendor studies at the Idaho National Laboratory (INL) Advanced Test Reactor (ATR), a pilot study for how to enhance the plant design modification work process, the collection of feedback from a field evaluation study at Plant Vogtle, and path forward to

    In general, any assessment concerning the safety of nuclear facilities is based on acquired scientific knowledge. Nevertheless, some areas related to safety remain still inadequately explored, knowledge in these areas needs to be further developed either through the results obtained from studies or from experimental research. With the aim of achieving an optimal safety level, one of IPSN's main tasks is to highlight these gags in current knowledge and point out to nuclear facility operators the need to fill them. These general considerations are pertinent to the particular field of fire. At IPSN, safety assessment activities and research are carried out side-by-side, thus facilitating the implementation of corresponding research programs. This ability to orient research with respect to safety assessment requirements, the contribution of research scientists to safety assessment or the formulation of safety problems, are today counted among the strong points of IPSN operation. This paper presents also the present main fire risk safety concerns for Nuclear Power Plants and the associated research carried out by IPSN (past, underway and future) to improve the scientific knowledge in the related areas.

    The goal of the U.S. Department of Energy Used Fuel Disposition’s (UFD) Deep Borehole Field Test is to drill two 5 km large-diameter boreholes: a characterization borehole with a bottom-hole diameter of 8.5 inches and a field test borehole with a bottom-hole diameter of 17 inches. These boreholes will be used to demonstrate the ability to drill such holes in crystalline rocks, effectively characterize the bedrock repository system using geophysical, geochemical, and hydrological techniques, and emplace and retrieve test waste packages. These studies will be used to test the deep borehole disposal concept, which requires a hydrologically isolated environment characterized by low permeability, stable fluid density, reducing fluid chemistry conditions, and an effective borehole seal. During FY16, Lawrence Berkeley National Laboratory scientists conducted a number of research studies to support the UFD Deep Borehole Field Test effort. This work included providing supporting data for the Los Alamos National Laboratory geologic framework model for the proposed deep borehole site, conducting an analog study using an extensive suite of geoscience data and samples from a deep (2.5 km) research borehole in Sweden, conducting laboratory experiments and coupled process modeling related to borehole seals, and developing a suite of potential techniques that could be applied to the characterization and monitoring of the deep borehole environment. The results of these studies are presented in this report.

    This paper reports that research and field support roles in the oilfield service industry have become increasingly complex in the last 15 years. Experimental apparatus are more dependent on the data-acquisition and processing capabilities of computers as the amount of data generated increases. Therefore, the need to network these computers for data transport has significantly increased. The type of network system selected depends on the goals to be achieved. Incorporation of existing equipment, communication between systems of different architectures, and future expandability are only a few of the necessary attributes. With these in mind, a computer network system was designed and is being implemented. The system combines local- and wide-area networks (LAN's or WAN's) of different protocols to acquire, process, and transport information worldwide. The result is faster development of new products and quicker response in support of field operations

  17. About soil cover heterogeneity of agricultural research stations' experimental fields

    Science.gov (United States)

    2013-04-01

    Depending on local pedo-ecological conditions (topography, (geo) diversity of soil parent material, meteorological conditions) the patterns of soil cover and plant cover determined by soils are very diverse. Formed in the course of soil-plant mutual relationship, the natural ecosystems are always influenced to certain extent by the other local soil forming conditions or they are site specific. The agricultural land use or the formation of agro-ecosystems depends foremost on the suitability of soils for the cultivation of feed and food crops. As a rule, the most fertile or the best soils of the area, which do not present any or present as little as possible constraints for agricultural land use, are selected for this purpose. Compared with conventional field soils, the requirements for the experimental fields' soil cover quality are much higher. Experimental area soils and soil cover composition should correspond to local pedo-ecological conditions and, in addition to that, represent the soil types dominating in the region, whereas the fields should be as homogeneous as possible. The soil cover heterogeneity of seven arable land blocks of three research stations (Jõgeva, Kuusiku and Olustvere) was studied 1) by examining the large scale (1:10 000) digital soil map (available via the internet), and 2) by field researches using the transect method. The stages of soils litho-genetic and moisture heterogeneities were estimated by using the Estonian normal soils matrix, however, the heterogeneity of top- and subsoil texture by using the soil texture matrix. The quality and variability of experimental fields' soils humus status, was studied more thoroughly from the aspect of humus concentration (g kg-1), humus cover thickness (cm) and humus stocks (Mg ha-1).

    FAIMS Mobile is a native Android application supported by an Ubuntu server facilitating human-mediated field research across disciplines. It consists of 'core' Java and Ruby software providing a platform for data capture, which can be deeply customised using 'definition packets' consisting of XML documents (data schema and UI) and Beanshell scripts (automation). Definition packets can also be generated using an XML-based domain-specific language, making customisation easier. FAIMS Mobile includes features allowing rich and efficient data capture tailored to the needs of fieldwork. It also promotes synthetic research and improves transparency and reproducibility through the production of comprehensive datasets that can be mapped to vocabularies or ontologies as they are created.

  19. Practical methods for generating alternating magnetic fields for biomedical research

    Alternating magnetic fields (AMFs) cause magnetic nanoparticles (MNPs) to dissipate heat while leaving surrounding tissue unharmed, a mechanism that serves as the basis for a variety of emerging biomedical technologies. Unfortunately, the challenges and costs of developing experimental setups commonly used to produce AMFs with suitable field amplitudes and frequencies present a barrier to researchers. This paper first presents a simple, cost-effective, and robust alternative for small AMF working volumes that uses soft ferromagnetic cores to focus the flux into a gap. As the experimental length scale increases to accommodate animal models (working volumes of 100s of cm3 or greater), poor thermal conductivity and volumetrically scaled core losses render that strategy ineffective. Comparatively feasible strategies for these larger volumes instead use low loss resonant tank circuits to generate circulating currents of 1 kA or greater in order to produce the comparable field amplitudes. These principles can be extended to the problem of identifying practical routes for scaling AMF setups to humans, an infrequently acknowledged challenge that influences the extent to which many applications of MNPs may ever become clinically relevant.

  20. Lessons in collaboration and effective field research from the Appalachian Headwaters Research Experience for Undergraduates Program

    2009-12-01

    In the summer of 2009, the authors launched year one of a three-year National Science Foundation-funded Research Experience for Undergraduates entitled "Carbon Storage and Headwater Health in the Appalachian Headwaters." Eight undergraduates selected from a nationally competitive field of more than 60 applicants participated in the ten-week field- and laboratory-based program along with three middle- and high-school teachers. Each student developed and completed an independent research project related to coal mining’s impact on soil organic carbon and sediment transport processes. Specifically, they used isotope ratio mass spectrometry to measure the carbon and nitrogen stable isotopic signature of soils and sediments in the Appalachian headwater landscapes and first order streams of Kentucky's southeastern coalfields. Among the program's innovative features was its fundamentally collaborative nature--which was represented in several ways. First, the background of the three program leaders was very different: an environmental planner with an academic background in land use planning and administration (Jones); a civil engineer trained in biogeochemistry and watershed modeling (Fox); and an environmental educator experienced in both formal and nonformal educator training and certification (Wilder). The program was also a collaboration between a Carnegie 1 research-oriented institution and an undergraduate/ teaching -focused regional comprehensive university. Finally, the participants themselves represented a diversity of disciplines and institutional backgrounds--including biology, geology, chemistry, environmental science and civil engineering. The Research Experience for Teachers component was another innovative program element. The teachers participated in all field and laboratory research activities during the first six weeks, then developed a unit of study for their own classrooms to be implemented during the current school year. In addition to the six

    This report is divided into six main sections. The first outlines the conceptual framework and methodology stressing the limitations that impede greater depth of analysis. The second, on the types and directions of research and development (R and D) activities in Latin America, is divided into three subsections, covering New and Renewable Sources of Energy (NRSE); conventional energy (including nuclear energy); and integrated energy resource R and D (primarily energy conservation and substitution, as well as energy policy and planning studies). In each subsection, I endeavoured to describe and critically assess R and D activities, achievements, and failures within the context of the limitations. Conclusions and recommendations in each case are implicitly or explicitly made depending on the field. In the third section, the state of science and technology policy on energy resources is presented. The fourth section draws together the conclusions and recommendations on further work to be done. The fifth section is a bibliography of 64 annotated and 52 unannotated items and the sixth, an appendix, is a directory of people working in the field of energy research

    As stated in the Wild Horse Fertility Control Field Trial Plan, the Bureau of Land Management (BLM) has an immediate need for a safe, effective contraceptive agent to assist in the management of the large number of wild horses on western rangelands. The BLM and the U.S. Geological Survey-Biological Resources Discipline (USGS/BRD) are testing the immunocontraceptive agent Porcine Zonae Pellucida (PZP) in field trials with three free-roaming herds of western wild horses. Extensive research has already been conducted on the safety, efficacy, and duration of PZP applications in both domestic and feral horses on eastern barrier islands and in some select trials I with wild horses in Nevada managed by the BLM. However, significant questions remain concerning the effects of I PZP application at the population level in the wild, as well as effects at the individual level on behavior, social structure, and harem dynamics of free-ranging animals. These questions are best answered with field trials on wild horse herds under a tight research protocol. The ultimate goal is to provide the BLM with the protocols and information necessary to begin using fertility control to regulate population growth rates in wild horse herds on a broader scale. Fertility control is intended to assist the conventional capture, removal, and adoption process as a I means of controlling excess numbers of wild horses and burros, and to greatly reduce the adoption costs and numbers of animals handled. Fertility control is not intended to totally replace the removal and adoption process.

    Social networks, such as Twitter, have become important sources for active monitoring of user-reported adverse drug reactions (ADRs). Automatic extraction of ADR information can be crucial for healthcare providers, drug manufacturers, and consumers. However, because of the non-standard nature of social media language, automatically extracted ADR mentions need to be mapped to standard forms before they can be used by operational pharmacovigilance systems. We propose a modular natural language processing pipeline for mapping (normalizing) colloquial mentions of ADRs to their corresponding standardized identifiers. We seek to accomplish this task and enable customization of the pipeline so that distinct unlabeled free text resources can be incorporated to use the system for other normalization tasks. Our approach, which we call Hybrid Semantic Analysis (HSA), sequentially employs rule-based and semantic matching algorithms for mapping user-generated mentions to concept IDs in the Unified Medical Language System vocabulary. The semantic matching component of HSA is adaptive in nature and uses a regression model to combine various measures of semantic relatedness and resources to optimize normalization performance on the selected data source. On a publicly available corpus, our normalization method achieves 0.502 recall and 0.823 precision (F-measure: 0.624). Our proposed method outperforms a baseline based on latent semantic analysis and another that uses MetaMap.

    Networking collaborative research and training in Asian developing countries includes three types of joint activities: field studies of workplace potentials for better safety and health, intensive action training for improvement of working conditions in small enterprises, and action-oriented workshops on low-cost improvements for managers, workers, and farmers. These activities were aimed at identifying workable strategies for making locally adjusted improvements in occupational health and ergonomics. Many improvements have resulted as direct outcomes. Most these improvements were multifaceted, low-cost, and practicable using local skills. Three common features of these interactive processes seem important in facilitating realistic improvements: 1) voluntary approaches building on local achievements; 2) the use of practical methods for identifying multiple improvements; and 3) participatory steps for achieving low-cost results first. The effective use of group work tools is crucial. Stepwise training packages have thus proven useful for promoting local problem-solving interventions based on voluntary initiatives.

    The Field Research Center (FRC) in Oak Ridge (Fig. 1), Tennessee supports the U.S. Department of Energy's (DOE's) Environmental Remediation Sciences Program (ERSP) goal of understanding the complex physical, chemical, and biological properties of contaminated sites for new solutions to environmental remediation and long-term stewardship. In particular, the FRC provides the opportunity for researchers to conduct studies that promote the understanding of the processes that influence the transport and fate of subsurface contaminants, the effectiveness and long-term consequences of existing remediation options, and the development of improved remediation strategies. It offers a series of contaminated sites around the former S-3 Waste Disposal Ponds and uncontaminated sites in which investigators and students conduct field research or collect samples for laboratory analysis. FRC research also spurs the development of new and improved characterization and monitoring tools. Site specific knowledge gained from research conducted at the FRC also provides the DOE-Oak Ridge Office of Environmental Management (EM) the critical scientific knowledge needed to make cleanup decisions for the S-3 Ponds and other sites on the Oak Ridge Reservation (ORR)

    Traditionally text mention normalization corpora have normalized concepts to single ontology identifiers ("pre-coordinated concepts"). Less frequently, normalization corpora have used concepts with multiple identifiers ("post-coordinated concepts") but the additional identifiers have been restricted to a defined set of relationships to the core concept. This approach limits the ability of the normalization process to express semantic meaning. We generated a freely available corpus using post-coordinated concepts without a defined set of relationships that we term "compositional concepts" to evaluate their use in clinical text. We annotated 5397 disorder mentions from the ShARe corpus to SNOMED CT that were previously normalized as "CUI-less" in the "SemEval-2015 Task 14" shared task because they lacked a pre-coordinated mapping. Unlike the previous normalization method, we do not restrict concept mappings to a particular set of the Unified Medical Language System (UMLS) semantic types and allow normalization to occur to multiple UMLS Concept Unique Identifiers (CUIs). We computed annotator agreement and assessed semantic coverage with this method. We generated the largest clinical text normalization corpus to date with mappings to multiple identifiers and made it freely available. All but 8 of the 5397 disorder mentions were normalized using this methodology. Annotator agreement ranged from 52.4% using the strictest metric (exact matching) to 78.2% using a hierarchical agreement that measures the overlap of shared ancestral nodes. Our results provide evidence that compositional concepts can increase semantic coverage in clinical text. To our knowledge we provide the first freely available corpus of compositional concept annotation in clinical text.

    Because vital details of potential pharmacokinetic drug-drug interactions are often described in free-text structured product labels, manual curation is a necessary but expensive step in the development of electronic drug-drug interaction information resources. The use of nonexperts to annotate potential drug-drug interaction (PDDI) mentions in drug product label annotation may be a means of lessening the burden of manual curation. Our goal was to explore the practicality of using nonexpert participants to annotate drug-drug interaction descriptions from structured product labels. By presenting annotation tasks to both pharmacy experts and relatively naïve participants, we hoped to demonstrate the feasibility of using nonexpert annotators for drug-drug information annotation. We were also interested in exploring whether and to what extent natural language processing (NLP) preannotation helped improve task completion time, accuracy, and subjective satisfaction. Two experts and 4 nonexperts were asked to annotate 208 structured product label sections under 4 conditions completed sequentially: (1) no NLP assistance, (2) preannotation of drug mentions, (3) preannotation of drug mentions and PDDIs, and (4) a repeat of the no-annotation condition. Results were evaluated within the 2 groups and relative to an existing gold standard. Participants were asked to provide reports on the time required to complete tasks and their perceptions of task difficulty. One of the experts and 3 of the nonexperts completed all tasks. Annotation results from the nonexpert group were relatively strong in every scenario and better than the performance of the NLP pipeline. The expert and 2 of the nonexperts were able to complete most tasks in less than 3 hours. Usability perceptions were generally positive (3.67 for expert, mean of 3.33 for nonexperts). The results suggest that nonexpert annotation might be a feasible option for comprehensive labeling of annotated PDDIs across a broader

    The aim of this special issue on science communication is to inspire and help scientists who are taking part or want to take part in science communication and engage with the wider public, clinicians, other scientists or policy makers. For this, some articles provide concise and accessible advice to individual scientists, science networks, or learned societies on how to communicate effectively; others share rationales, objectives and aims, experiences, implementation strategies and resources derived from existing long-term science communication initiatives. Although this issue is primarily addressing scientists working in the field of biomedical research, much of it similarly applies to scientists from other disciplines. Furthermore, we hope that this issue will also be used as a helpful resource by academic science communicators and social scientists, as a collection that highlights some of the major communication challenges that the biomedical sciences face, and which provides interesting case studies of initiatives that use a breadth of strategies to address these challenges. In this editorial, we first discuss why we should communicate our science and contemplate some of the different approaches, aspirations and definitions of science communication. We then address the specific challenges that researchers in the biomedical sciences are faced with when engaging with wider audiences. Finally, we explain the rationales and contents of the different articles in this issue and the various science communication initiatives and strategies discussed in each of them, whilst also providing some information on the wide range of further science communication activities in the biomedical sciences that could not all be covered here.

    Full Text Available The state of evolution of attitudes in a sample of 142 Medical Students at the Pontificia Universidad Javeriana in Bogota (at the beginning, middle and ending of their studies in the field of Human Research Ethics (HRE is analytically described. A complex scale of attitudes was used, with three components: affective, beliefs-related and behavioral, further divided into three theoretical categories taken from Bioethics: Subject-End/means- Dignity, Benefit and Justice. The relationship between the current medical education process and the attitudes regarding HRE in the sample are analyzed.A small trend towards progress in all categories and in all components of attitudes throughout medical education is described; neither the Benefit nor the Subject-End/means/Dignity categories evolve in a significant way; some significant differences were observed in the Justice category (beliefs and behavioral and in the Subject-End/means-Dignity category (beliefs component. The results allow for asking about the role of formation and evolution of those attitudes throughout the academic process. In conclusion, attitudes seem to be progressing relatively, without a decisive evolution.

    Most educational institutions lack a structured system that provides undergraduate students with research exposure in the medical field. The objective of this paper is to describe the structure of the Medical Research Volunteer Program (MRVP) which was established at the American University of Beirut, Lebanon, as well as to assess the success of the program. The MRVP is a program that targets undergraduate students interested in becoming involved in the medical research field early on in their academic career. It provides students with an active experience and the opportunity to learn from and support physicians, clinical researchers, basic science researchers and other health professionals. Through this program, students are assigned to researchers and become part of a research team where they observe and aid on a volunteer basis. This paper presents the MRVP's four major pillars: the students, the faculty members, the MRVP committee, and the online portal. Moreover, details of the MRVP process are provided. The success of the program was assessed by carrying out analyses using information gathered from the MRVP participants (both students and faculty). Satisfaction with the program was assessed using a set of questions rated on a Likert scale, ranging from 1 (lowest satisfaction) to 5 (highest satisfaction). A total of 211 students applied to the program with a total of 164 matches being completed. Since the beginning of the program, three students have each co-authored a publication in peer-reviewed journals with their respective faculty members. The majority of the students rated the program positively. Of the total number of students who completed the program period, 35.1 % rated the effectiveness of the program with a 5, 54.8 % rated 4, and 8.6 % rated 3. A small number of students gave lower ratings of 2 and 1 (1.1 % and 0.4 %, respectively). The MRVP is a program that provides undergraduate students with the opportunity to learn about research firsthand

    Social media postings are rich in information that often remain hidden and inaccessible for automatic extraction due to inherent limitations of the site's APIs, which mostly limit access via specific keyword-based searches (and limit both the number of keywords and the number of postings that are returned). When mining social media for drug mentions, one of the first problems to solve is how to derive a list of variants of the drug name (common misspellings) that can capture a sufficient number of postings. We present here an approach that filters the potential variants based on the intuition that, faced with the task of writing an unfamiliar, complex word (the drug name), users will tend to revert to phonetic spelling, and we thus give preference to variants that reflect the phonemes of the correct spelling. The algorithm allowed us to capture 50.4 - 56.0 % of the user comments using only about 18% of the variants.

    The generation of large pressures by magnetic fields to obtain equation of state information is of fairly recent origin. Magnetic fields used in compression experiments produce an almost isentropic sample compression. Axial magnetic field compression is discussed together with a few results chosen to show both advantages and limitations of the method. Magnetic compression with azimuthal fields is then considered. Although there are several potential pitfalls, the possibilities are encouraging for obtaining very large pressures. Next, improved diagnostic techniques are considered. An x-ray ''streaking camera'' is proposed for volume measurements and a more detailed discussion is given on the use of the shift of the ruby fluorescence lines for pressure measurements. Finally, some additional flux compression magnetic field sources are discussed briefly. 5 figures, 2 tables

    Two systems for exposure and sham-exposure of large numbers of rats and mice to uniform, vertical, 60-Hz electric fields have been constructed. The rat system contains four racks of four rectangular 1.0m x 2.2m exposure-electrodes that are stacked vertically with a separation between adjacent electrodes of 0.41 m. Any two of the four exposure racks may be energized to a maximum field strength of 150 kV/m. Each exposure electrode is equipped with 24 Lexan cages, each of which holds a single rat. The cage floor is a stainless steel screen that serves as one electrode. The system for watering animals is contained entirely within the electrode and does not protrude above the cage's floor, thereby preventing distortion of the exposure field and electrical shock or discharge as the animal drinks. The total capacity of the system is 288 rats. A similar system of two racks of five electrodes each is used to expose as many as 450 mice to fields at a maximum strength of 150 kV/m while sham exposing an equal number. Measurements of the electric field reveal an overall uniformity within 4% over the area to be occupied by experimental animals. The field inside a Lexan cage is reduced by about 3%. No corona-discharge has been detected. Measurements of ozone concentration in the rat and mouse exposure systems show no difference from background levels. Harmonic distortion has been eliminated by damping and filtering the high-voltage supply. Animals housed in close proximity are partially shielded from the electric field; the total body current in a rat model is reduced by 35 ± 5% when rats are placed in adjacent cages. (author)

    Full Text Available For expanding the application scope of car-following, based on the basic idea of the noncontact interaction of the objects in physics, establish an attention field model to describe the driving behavior. Firstly, propose the time distance concept to describe the degree of driver perception to the front one-dimensional space and extend its application range to the two-dimensional space. Secondly, connect the point which has the same time distance to constitute the equipotential line of drivers’ attention field equipotent, and establish a model to describe it. Thirdly, define the effective range of the driver’s psychological field with the feature of the driver’s visual distance range increasing and the angle decreasing. Finally, design the calculation method to collect projection of the object in the psychological field scope and calculate the curve points to determine the object’s intensity of psychological field. Preliminarily build the driving behavior model and use the numerical simulation method to simulate the simple transport scenarios; initially verify the validity of the model.

    Full Text Available This article is about the role of film in interaction and product design research with technology, and the use of film in exploring and explaining emerging technologies in multiple contexts. We have engaged in a reflective design research process that uses graphical, audiovisual, and time-based media as a tool, a material and a communicative artefact that enables us to approach complex, obscure and often invisible emerging technologies. We give a discursive account of how film has played an intricate role in our design research practice, from revealing the materiality of invisible wireless technology, to explaining complex technical prototypes, to communicating to a public audience through online films that may fold broader social and cultural discourses back into our design research process. We conclude by elaborating on discursive design approaches to research that use film as a reflective and communicative medium that allows for design research to operate within a social and cultural frame.

    Recent experimental results are discussed for a compact toroid produced by a field-reversed theta-pinch and containing purely poloidal magnetic fields. The confinement time is found to vary inversely with the ion gyro-radius and to be approximately independent of ion temperature for fixed gyro-radius. Within a coil of fixed radius, the plasmoid major radius R was varied by approx. 30% and the confinement appears to scale as R/sup 2/. A semi-empirical formation model has been formulated that predicts reasonably well the plasma parameters as magnetic field and fill pressure are varied in present experiments. The model is used to predict parameters in larger devices under construction.

    Recent experimental results are discussed for a compact toroid produced by a field-reversed theta-pinch and containing purely poloidal magnetic fields. The confinement time is found to vary inversely with the ion gyro-radius and to be approximately independent of ion temperature for fixed gyro-radius. Within a coil of fixed radius, the plasmoid major radius R was varied by approx. 30% and the confinement appears to scale as R 2 . A semi-empirical formation model has been formulated that predicts reasonably well the plasma parameters as magnetic field and fill pressure are varied in present experiments. The model is used to predict parameters in larger devices under construction

    2014-01-01

    The Nuclear Regulation Authority (NRA) published the investigation and examination report on the unexplained issues raised by the National Diet Investigation Commission; 'Analysis of the TEPCO Fukushima Daiichi NPS Accident-Interim Report' in October 2014. The NRA had analyzed seven unexplained issues raised in the National Diet Investigation Commission report, and compiled the results. The author insisted the report should include related views and lessons learned and not just explain investigated and examined phenomena in order to contribute to ensuring nuclear safety in the world. As an example, the author selected the fifth of seven issues; 'operating status of the Isolation Condenser of Unit 1 (IC)'. The report concluded 'the AC-driven valve was closed since the AC power supply kept working even after DC power supply for the IC rupture detection circuit was lost. The isolation valves (2A and 2B) outside the PCV were closed, but isolation valves (1B and 4B) of the IC (system 'B') in the PCV remained open. However, the operating status (open/close) of isolation valves (1A and 4A) of the IC (system 'A') in the PCV is not clear. It is therefore necessary to continue analyses of this issue.' As related important points not mentioned in the report, the author described five points; (1) timing of functional losses of IC system, (2) obsolete aspect of equipment arrangement design (system separation), (3) single failure vulnerability, (4) rolling out issue of IC system to RCIC system (horizontal deployment) and (5) lessons learned from risk-informed 'black swan event'.

    International Nuclear Information System (INIS)

    Mauro, F.; Lovisolo, G.A.; Raganella, L.

    1992-01-01

    Although it is commonly accepted that exposure to high levels of electromagnetic, micro- and radiofrequency waves produces harmful effects to the health of man, the formulation of exposure limits is still an open process and dependent upon the evolving level of knowledge in this field. This paper surveys the current level of knowledge gained through 'in vitro' and 'in vivo' radiological and epidemiological studies on different types of electromagnetic radiation derived effects - chromosomal, mutagenic, carcinogenic. It then reviews efforts by international organizations, e. g., the International Radiation Protection Association, to establish exposure limits for radiofrequency electromagnetic fields. Brief notes are given on the electromagnetic radiation monitoring campaign being performed by public health authorities in the Lazio Region of Italy

  18. Short presentation on some researches activities about near field earthquakes

    International Nuclear Information System (INIS)

    Donald, John

    2002-01-01

    The major hazard posed by earthquakes is often thought to be due to moderate to large magnitude events. However, there have been many cases where earthquakes of moderate and even small magnitude have caused very significant destruction when they have coincided with population centres. Even though the area of intense ground shaking caused by such events is generally small, the epicentral motions can be severe enough to cause damage even in well-engineered structures. Two issues are addressed here, the first being the identification of the minimum earthquake magnitude likely to cause damage to engineered structures and the limits of the near-field for small-to-moderate magnitude earthquakes. The second issue addressed is whether features of near-field ground motions such as directivity, which can significantly enhance the destructive potential, occur in small-to-moderate magnitude events. The accelerograms from the 1986 San Salvador (El Salvador) earthquake indicate that it may be non conservative to assume that near-field directivity effects only need to be considered for earthquakes of moment magnitude M 6.5 and greater.

    Research librarians no longer need to perform as many of the traditional the chores of the research library. This is due to many factors like digitalization, changing research policies and changes in researchers’ behaviour. With these changes also comes a demand for new skills. We seek an answer...... to how this demand can be met. We argue that changes that has taken place in the research library has also led to a loss of prestige for the research librarians. We use Bourdieu’s field theory to analyse the power struggles in the academic field and in the field of the research library and to identify...

    Jia, Wen-Kui

    The use of a balloon to explore the geomagnetic field anomaly in the area east of Beijing is demonstrated. The present results are compared with those of aerial surveys. Descriptions are given of the fluxgate magnetometer, the sensor's attitude control and measurement, and data transmission and processing. At an altitude of about 30 km, a positive anomaly of the vertical component of about 100 nanoteslas was measured. The results suggest that, for this particular area, the shallow layer of a small-scale geological structure differs from the deep layer of a large-scale geological structure.

  14. Transformative consumer research: Its origins and possible enrichment of the field of consumer research in South Africa

    Directory of Open Access Journals (Sweden)

    Leona M. Ungerer

    2014-06-01

    Research purpose: The purpose of this study is to explore the principles underlying transformative consumer research, including how it differs from traditional research methods and pointing out some established research areas in this field. Motivation for the study: Apart from pointing to a lack of literature, this article highlights the relevance of this approach for emerging countries by investigating the principles and practices embedded in transformative consumer research. It provides some indication of how an investigation of these areas may contribute to enhancing the relevance of consumer research to its various stakeholders. Research design, approach and method: The author used a literature review to conduct the study. Main findings: It appears that consumer research currently lacks external and internal relevance. A transformative consumer-research approach may address some of the fundamental problems in the way consumer psychologists plan and conduct their research, contributing to this lack of relevance. Practical/managerial implications: Most stages of the traditional research approach may need to be adapted for transformative research purposes. Some approaches appear particularly suited to transformative consumer research, including revelatory, incendiary, policy, participatory and coalition research. Contribution/value-add: This study’s primary contribution stems from suggesting a rather novel additional approach to enhance the relevance of consumer research in South Africa, pointing out some established practices in the field of transformative consumer research and suggesting how they may augment consumer research in South Africa.

  15. A Guide to Field Notes for Qualitative Research: Context and Conversation.

    Science.gov (United States)

    Phillippi, Julia; Lauderdale, Jana

    2018-02-01

    Field notes are widely recommended in qualitative research as a means of documenting needed contextual information. With growing use of data sharing, secondary analysis, and metasynthesis, field notes ensure rich context persists beyond the original research team. However, while widely regarded as essential, there is not a guide to field note collection within the literature to guide researchers. Using the qualitative literature and previous research experience, we provide a concise guide to collection, incorporation, and dissemination of field notes. We provide a description of field note content for contextualization of an entire study as well as individual interviews and focus groups. In addition, we provide two "sketch note" guides, one for study context and one for individual interviews or focus groups for use in the field. Our guides are congruent with many qualitative and mixed methodologies and ensure contextual information is collected, stored, and disseminated as an essential component of ethical, rigorous qualitative research.

    Although still in its infant stage, synthetic biology has achieved remarkable development and progress during the past decade. Synthetic biology applies engineering principles to design and construct gene circuits uploaded into living cells or organisms to perform novel or improved functions, and it has been widely used in many fields. In this review, we describe the recent advances of mammalian synthetic biology for the treatment of diseases. We introduce common tools and design principles of synthetic gene circuits, and then we demonstrate open-loop gene circuits induced by different trigger molecules used in disease diagnosis and close-loop gene circuits used for biomedical applications. Finally, we discuss the perspectives and potential challenges of synthetic biology for clinical applications.

    2015-01-01

    The research areas as well as the knowledge gained for the practical use of robots are growing and expanding beyond manufacturing and industrial automation, making inroads in sectors such as health care and terrain sensing, as well as general assistive systems working in close interaction with humans. In a situation like this, it is necessary for future robot systems to become less stiff and more specialized by taking inspiration from the mechanical compliance and versatility found in natural materials and organisms. At present, a new discipline is emerging in this area, called »Soft Robotics«. It particularly challenges the traditional thinking of engineers, as the confluence of technologies, ranging from new materials, sensors, actuators and production techniques to new design tools, will make it possible to create new systems whose structures are almost completely made of soft materials, which bring about entirely new functions and behaviors, similar in many ways to natural systems.

    The research in question has explored 39 central notions of the environmental discussion as to its semantic and meaning for persons and institutions - from waste incineration to the dying of woods. The interviewed were asked to give a semantic profile, a common description, the positive, the negative aspects as well as synonyms/alternatives for every notion. 200 members of institutions (out of the sections of economy, public institutions, environmental initiatives) and consumers were questioned. The results show, that single notions that are of high significance to an institutional section of the consumers may mean little to other institutional sections and vice versa. If a notion is regarded as unimportant, communication with this notion and about the corresponding facts will hardly be possible. Depending on the point of interest notions are used in totally different meanings. The differences in meaning are revealed. (orig.) With 7 tabs., 38 diagrams [de

  4. Pharmacovigilance from social media: mining adverse drug reaction mentions using sequence labeling with word embedding cluster features.

    2015-05-01

    Social media is becoming increasingly popular as a platform for sharing personal health-related information. This information can be utilized for public health monitoring tasks, particularly for pharmacovigilance, via the use of natural language processing (NLP) techniques. However, the language in social media is highly informal, and user-expressed medical concepts are often nontechnical, descriptive, and challenging to extract. There has been limited progress in addressing these challenges, and thus far, advanced machine learning-based NLP techniques have been underutilized. Our objective is to design a machine learning-based approach to extract mentions of adverse drug reactions (ADRs) from highly informal text in social media. We introduce ADRMine, a machine learning-based concept extraction system that uses conditional random fields (CRFs). ADRMine utilizes a variety of features, including a novel feature for modeling words' semantic similarities. The similarities are modeled by clustering words based on unsupervised, pretrained word representation vectors (embeddings) generated from unlabeled user posts in social media using a deep learning technique. ADRMine outperforms several strong baseline systems in the ADR extraction task by achieving an F-measure of 0.82. Feature analysis demonstrates that the proposed word cluster features significantly improve extraction performance. It is possible to extract complex medical concepts, with relatively high performance, from informal, user-generated content. Our approach is particularly scalable, suitable for social media mining, as it relies on large volumes of unlabeled data, thus diminishing the need for large, annotated training data sets. © The Author 2015.

  5. Urban geomorphological heritage - A new field of research

    Science.gov (United States)

    Reynard, Emmanuel; Pica, Alessia; Coratza, Paola

    2017-04-01

    Urbanization is one of the major challenges that the world faces. In 2015, 54% of the world population was living in urban areas and in some countries this percentage is close to 100% (Singapore 100%; Qatar 99%; Belgium 98%). In several parts of the world annual urbanization rates exceed 5% (e.g. Oman 8.54%; Rwanda 6.43%; Burkina Faso 5.87%), which means that urban sprawl is a widespread phenomenon. Urbanization and correlated infrastructure building highly impact and sometimes completely destroy natural landforms. Geomorphological heritage research has traditionally focused on rural or natural regions, in particular protected areas (nature parks, geoparks). We consider that urban areas, which have been poorly investigated until now, are particularly interesting in a geomorphological heritage point of view for almost three reasons: (i) The geomorphological context (site) of some cities is part of their "image" and their fame (e.g. the sugarloaf of Rio de Janeiro); (ii) Urban sprawl often interacts with landforms, which addresses the challenge of geoheritage protection in fast urbanizing areas; (iii) Cities are often tourist destinations, which creates a potential for a geotourist promotion of their geomorphological heritage. This study addresses the main challenges research on geomorphological heritage is facing in urban contexts: (i) the complex interrelationships between natural landforms and urban forms; (ii) the partial or total invisibility of landforms and sediments that are covered or destroyed by urban infrastructures; (iii) man-made landforms as part of urban geomorphological heritage; (iv) the suitability of some landforms (valleys, gullies, mounts) for specific urban uses; (v) the geomorphic constraints of landforms on urban development; and (vi) the importance of some landforms for the urban landscape and the image of the cities. To address these challenges a methodological framework is proposed, which combines: (i) the geomorphological analysis of the

    Implementation Research (IR) in and around health systems comes with unique challenges for researchers including implementation, multi-layer governance, and ethical issues. Partnerships between researchers, implementers, policy makers and community members are central to IR and come with additional challenges. In this paper, we elaborate on the challenges faced by frontline field researchers, drawing from experience with an IR study on Village Health Sanitation and Nutrition Committees (VHSNCs). The IR on VHSNC took place in one state/province in India over an 18-month research period. The IR study had twin components; intervention and in-depth research. The intervention sought to strengthen the VHSNC functioning, and concurrently the research arm sought to understand the contextual factors, pathways and mechanism affecting VHSNC functions. Frontline researchers were employed for data collection and a research assistant was living in the study sites. The frontline research assistant experienced a range of challenges, while collecting data from the study sites, which were documented as field memos and analysed using inductive content analysis approach. Due to the relational nature of IR, the challenges coalesced around two sets of relationships (a) between the community and frontline researchers and (b) between implementers and frontline researchers. In the community, the frontline researcher was viewed as the supervisor of the intervention and was perceived by the community to have power to bring about beneficial changes with public services and facilities. Implementers expected help from the frontline researcher in problem-solving in VHSNCs, and feedback on community mobilization to improve their approaches. A concerted effort was undertaken by the whole research team to clarify and dispel concerns among the community and implementers through careful and constant communication. The strategies employed were both managerial, relational and reflexive in nature

    The geothermal reservoir in Tianjin can be divided into two parts: the upper one is the porous medium reservoir in the Tertiary system; the lower one includes the basement reservoir in Lower Paleozoic and Middle-Upper Proterozoic. Hot springs are exposed in the northern mountain and confined geothermal water is imbedded in the southern plain. The geothermal reservoir is incised by several fractures. In recent years, TDS of the geothermal water have gone up along with the production rate increasing, along the eastern fracture zone (Cangdong Fracture and West Baitangkou Fracture). This means that the northern fracture system is the main seepage channel of the deep circulation geothermal water, and the reservoir has good connection in a certain area and definite direction. The isotopic research about hydrogen and carbon chronology indicates that the main recharge period of geothermal water is the Holocene Epoch, the pluvial and chilly period of 20 kaBP. The karst conduits in weathered carbonate rocks of the Proterozoic and Lower Paleozoic and the northeast regional fracture system are the main feeding channels of Tianjin geothermal water. Since the Holocene epoch, the geothermal water stayed at a sealed warm period. The tracer test in WR45 doublet system shows that the tracer test is a very effective measure for understanding the reservoir's transport nature and predicting the cooling time and transport velocity during the reinjection. 3-D numerical simulation shows that if the reinjection well keeps a suitable distance from the production well, reinjection will be a highly effective measure to extract more thermal energy from the rock matrix. The cooling of the production well will not be a problem.

  11. A tale of two tools: Reliability and feasibility of social media measurement tools examining e-cigarette twitter mentions

    Directory of Open Access Journals (Sweden)

    Amelia Burke-Garcia

    Full Text Available Given 70% of Americans are seeking health information online, social media are becoming main sources of health-related information and discussions. Specifically, compounding rising trends in use of e-cigarettes in the US, there has been a rapid rise in e-cigarette marketing – much of which is happening on social media. Public health professionals seeking to understand consumer knowledge, attitudes and beliefs about e-cigarettes should consider analyzing social media data and to do so, there are numerous free and paid tools available. However, each uses different sources and processes, which makes data validation challenging. This exploratory study sought to understand the reliability and feasibility of two social media data tools analyzing e-cigarette tweets. Twitter mentions were pulled from two different industry standard tools (GNIP and Radian6 and data were evaluated on six measures, e.g. Cost, Feasibility, Ease of Use, Poster Type (individual/organization, Context (tweet content analysis, and Valence (positive/negative. Findings included similarities amongst the data sets in terms of the content themes but differences in cost and ease of use of the tools themselves. These findings align with prior research, notably that e-cigarette marketing tweets are most common and public health-related content is noticeably absent. Findings from this exploratory study can inform future social media studies as well as communication campaigns seeking to address the emerging issue of e-cigarette use. Keywords: E-cigarettes, Vaping, Twitter, Tweets, Social media

  12. Syntax mentioned seven times in the CEFR – and how many times at school, in foreign language classrooms?

    Directory of Open Access Journals (Sweden)

    Darja Mertelj

    2014-12-01

    Full Text Available In the teaching of foreign languages, complex-clause syntax does not seem to have had an established role over the last 20 years, especially within the communicative approach and, of course, the CEFR. It was previously part of methods which stressed formal approaches to foreign languages and their being taught, but not of natural, acquisition-based methods. With the communicative approach, two important premises were introduced: authentic texts and grammar as a tool when necessary. This is one probable reason why explicit, complex-clause syntax is hardly mentioned in the CEFR, even though it is implicitly present in descriptors, even though it is particularly recognisable in those for writing skills, and even though we know that it can be used for all four skills, as well as to guide learners towards some self-directed learning about language features. To date, in the era of the communicative approach, not much is known about the role of complex-clause syntax in foreign/second language classrooms, in particular from the learners’ viewpoint. In order to bridge this research gap, the paper analyses a questionnaire among learners in secondary schools that looked at their perspectives regarding the (possible role of syntax. The examined aspects consider its role for the four skills, and the benefits of knowing syntax; implicitly, the paper touches on some affective factors and related methodological approaches, along with problems concerning the teaching of syntax. The findings are based on quantitative data; an evaluation of the need for complex-clause syntax is included, and some pedagogical implications are presented.

    Full Text Available The inlet grid and exhaust grid are widely used in engineering machinery products. The process that airflow goes through grids is a complex turbulent flow and directly related to the heat dispersion and aerodynamic noise. The theoretical analysis result shows that the jet noise generated by airflow has a connection with the grid structure form, fluid flowing situation, and heat conduction. In addition, the influences of different grid structure forms (included the round hole, long hole, and square hole and porosity on the heat dissipation and aerodynamic noise were analyzed and presented based on the verified computational fluid dynamics (CFD model. Results show that the heat dispersion and aerodynamic noise of the round hole are most effective under the same porosity; as the porosity increases, the disturbance degree decreases and the noise reduction effect gets better. Finally, the research result provides the scientific basis for improving grid structure and achieving energy saving and noise reduction.

    Full Text Available Evolution of technology and its tremendous use in education has changed the ways of educational services in higher education around the world. There is worldwide access to higher education through virtual learning environments. This is a new avenue for 21st century education and within a short time, it has been able to establish new culture of learning i.e. e-learning or online learning. As a result, e-learning has been the greater field for educational research. In this context, this paper focuses on methodological issues of the Internet mediated research (e-Research with particular focus on virtual fields. Paper explores and discusses on possible sources of data, methods of data collection, process of analysis and ethical issues to adopt research with virtual fields. In doing so, the purpose is to reveal answer to the question: how do e-Researchers deal with methodological issues related to collecting data, determining data sources, data analysis/interpretation, and ethical considerations? Paper presents examples from the Internet mediated empirical studies. Conclusion of the paper is that e-field or cyberspace is an avenue for modern researchers. Researchers are supported with various Information Communication Technology (ICT tools for field access, data collection, analysis and interpretation. However, they need to pay full attention to deal with major issues such as locating and gaining access to virtual/Internet-mediated fields, selecting e-participants and working with them, and using varieties of ICT tools for data collection, analysis and interpretation.

    In this article I reflect on the peculiarities of contemporary ethnographic research, highlighting some challenges inherent to this process. The discussion focuses in particular on the following aspects: the limits imposed by the clear reduction in immersion time in the field; the challenges in learning about ethnographic work, either in the process of observation or interaction in the field, or in the task of textual production; issues of an epistemological and ethical nature that deserve particular attention on the part of practitioners of the ethnographic approach and the scientific community in general. It is especially appropriate to foster debate around the ethnographic method, addressing its peculiarities, operational complexity and potential as a tool for knowledge production, in the sphere of health/public health, bearing in mind the marked increase of this approach in this field.

    Little is known about the changes in the ranking of leading cause of death (COD) among people died with schizophrenia across years in the United States (U.S.). This study aims to determine the ranking of leading COD among U.S. decedents with mention of schizophrenia by age from 2000 to 2015. The mortality multiple COD files maintained by the National Center for Health Statistics were used to identify decedents aged 15 years old and above with mention of schizophrenia anywhere on the death certificates to determine the number and proportion of deaths attributed to various underlying CODs. Of 13,289, 13,655, 14,135, and 15,033 people who died in 2000-2003, 2004-2007, 2008-2011and 2012-2015 with mention of schizophrenia, similar to all decedents, heart disease and cancer was the first and the second leading COD throughout the study years. Schizophrenia ranked the third in most years except in 2004-2007. The first leading COD for decedents with mention of schizophrenia aged 15-24, 25-44, 45-64, 65-74, and 75+ years old in 2012-2015 was suicide, accidents, heart disease, heart disease, and Alzheimer's disease and related dementia, respectively. Nevertheless, it was accidents, accidents, cancer, cancer, and heart disease, respectively for all decedents. The ranking of leading CODs among U.S. decedents with mention of schizophrenia changed across years and differed from all decedents by age, which suggest that different interventions should be designed accordingly.

    Educating the next generation of scientists requires new educational methods and unconventional approaches to facilitate the interdisciplinary scholarship required to cope with fast-paced developments in the geosciences. We believe incorporation of field training with active research missions is an effective educational model. By participating in active research and open science dialogue, students are exposed to real-world examples of the principles and processes of complex systems in a manner that allows them to develop a deeper understanding of the subject. We find students are highly motivated by the knowledge that data they collect will advance the research mission; such an environment stokes their passions and imaginations and allows the students to explore the roots of their interest in geoscience. In this context, a two-week educational field course on hydrologic processes and measurements was integrated with ongoing research in Chile to understand the effect of soil shrinkage and swelling properties on watershed hydrologic response. Students witnessed the iterative process of field-experiment design and became part of science in the making. They experienced the complexity of field work and developed problem-solving skills through the myriad of challenges presented in the acquisition of field data in a remote area. All of these factors contributed to an atmosphere of creativity that led to an outstanding research and educational experience. We find the coupling of field training with active research to be extremely rewarding, and time- and cost-effective education in this fast-paced and cost-cautious age.

  9. [Qualitative research into the scientific production in the field of bioethics].

    Ribeiro, Carlos Dimas Martins; Maksud, Ivia; Claro, Lenita Barreto Lorena; Un, Julio Wong

    2014-07-01

    This article discusses the character and use of qualitative research methods in the field of bioethics. A systematic review of articles published in Latin American countries and selected from the SciELO database was conducted, with special emphasis on articles that employed qualitative research methodology. The set of articles reveals a field of bioethics composed of three distinct vectors. The first refers to the dual characterization of bioethics that can be defined as a social movement or as a discipline; the second differentiates bioethics from other fields of ethics, especially from predominantly deontology-based professional ethics; and the third is related to ethical approaches adopted in the analyses conducted in the research. A relatively insignificant part of these texts result from qualitative research and they can be divided into four categories according to their themes and guidelines: bioethics as a field and/or discourse; training in health; ethics, care, and clinical practice; formulation of health policy. The production shows, on the one hand, a relatively timid approach of social science researchers to the field of bioethics and, on the other hand, little use of qualitative methodologies in research in the field and, in some cases, a certain lack of precision regarding use of the methods.

    This report presents a survey of the most important work in the field of nuclear agronomy carried out in France since the second international conference, ranging from pure research to the most direct application. As the programmes develop, so to an ever decreasing degree does this differentiation cover the distinction made in the report between the biological radiations effects and the other uses of nuclear techniques. Thus research on agricultural radio-genetics is carried on in two directions: from the theoretical and methodological angle, with comparative studies of the action of various types of radiation, the influence of dose rate and temperature, the action of chemical mutation agents, the production of chimera by gamma irradiation; and on the practical side, leading to the creation of new, hardier or earlier varieties (rice, millet, ground-nuts). Problems of pest destruction (eradication) and the preservation of foodstuffs by irradiation are also tackled by widely varied means and for totally different purposes. One operation consisting of a simple irradiation (moist seeds, potatoes...) will sometimes be associated with original studies of a biochemical or microbiological nature (for example: decomposition of starch, glucide metabolism of irradiated tubers, radiation resistance of yeasts). The nuclear technique side is represented mainly by radioisotopes (carbon 14, phosphorus 32, sulphur 35, calcium 45, potassium 42, copper 64, gold 198) and stable isotopes analysed by mass spectrometer (nitrogen 15, oxygen 18) or by neutron activation (boron 10). The studies mentioned refer to problems on different levels concerning plant physiology, agrology, agricultural entomology and zootechny. Results obtained from measurements of the humidity (neutron thermalization) and density (gamma diffusion) of a soil are also given.

  12. Research Into the Role of Students’ Affective Domain While Learning Geology in Field Environments

    Science.gov (United States)

    Elkins, J.

    2009-12-01

    Existing research programs in field-based geocognition include assessment of cognitive, psychomotor, and affective domains. Assessment of the affective domain often involves the use of instruments and techniques uncommon to the geosciences. Research regarding the affective domain also commonly results in the collection and production of qualitative data that is difficult for geoscientists to analyze due to their lack of familiarity with these data sets. However, important information about students’ affective responses to learning in field environments can be obtained by using these methods. My research program focuses on data produced by students’ affective responses to field-based learning environments, primarily among students at the introductory level. For this research I developed a Likert-scale Novelty Space Survey, which presents student ‘novelty space’ (Orion and Hofstien, 1993) as a polygon; the larger the polygons, the more novelty students are experiencing. The axises for these polygons correspond to novelty domains involving geographic, social, cognitive, and psychological factors. In addition to the Novelty Space Survey, data which I have collected/generated includes focus group interviews on the role of recreational experiences in geology field programs. I have also collected data concerning the motivating factors that cause students to take photographs on field trips. The results of these studies give insight to the emotional responses students have to learning in the field and are important considerations for practitioners of teaching in these environments. Collaborative investigations among research programs that cross university departments and include multiple institutions is critical at this point in development of geocognition as a field due to unfamiliarity with cognitive science methodology by practitioners teaching geosciences and the dynamic nature of field work by cognitive scientists. However, combining the efforts of cognitive

    The study provides an overview of the research activity carried out in the field of cybernetics. To do so, all research papers from 1997 to 2011 (16,445 research papers) under the category of "Computer Science, Cybernetics" of Web of Science have been processed using our in-house software which is developed specifically for this purpose. Among its multiple capabilities, this software analyses individual and compound keywords, quantifies productivity taking into account the work distribution, estimates the impact of each article and determines the collaborations established at different scales. Keywords analysis identifies the evolution of the most important research topics in the field of cybernetics and their specificity in biological aspects, as well as the research topics with lesser interest. The analysis of productivity, impact and collaborations provides a framework to assess research activity in a specific and realistic context. The geographical and institutional distribution of publications reveals the leading countries and research centres, analysing their relation to main research journals. Moreover, collaborations analysis reveals great differences in terms of internationalization and complexity of research networks. The results of this study may be very useful for the characterization and the decisions made by research in the field of cybernetics.

    A primary advantage of place-based research is the multidisciplinary and interdisciplinary research that can be applied to a single locale, with a depth of continued study through time. Through the last decade, Lamont-Doherty's Secondary School Field Research Program (SSFRP) has promoted scientific inquiry, mostly among groups under-represented in STEM fields, in Piermont Marsh, a federally protected marsh in the Hudson estuary. At the same time, Lamont Doherty Earth Observatory (LDEO) scientists have become more involved, through mentoring by researchers, postdocs and graduate students, often paired with high school teachers. The sustained engagement of high school students in a natural environment, experiencing the Hudson River and its tidal cycles, protection of coastline, water quality improvement, native and invasive plant communities, is fundamental to their understanding of the importance of wetlands with their many ecosystem services. In addition, the Program has come to see "place" as inclusive of the Observatory itself. The students' work at Lamont expands their understanding of educational opportunities and career possibilities. Immersing students in a research atmosphere brings a level of serious inquiry and study to their lives and provides them with concrete contributions that they make to team efforts. Students select existing projects ranging from water quality to Phragmites removal, read papers weekly, take field measurements, produce lab results, and present their research at the end of six weeks. Ongoing results build from year to year in studies of fish populations, nutrients, and carbon sequestration, and the students have presented at professional scientific meetings. Through the Program students gain a sense of ownership over both their natural and the academic environments. Challenges include sustained funding of the program; segmenting the research for reproducible, robust results; fitting the projects to PIs' research goals, time

    Global health education and training of biomedical students in international and minority health research is expending through U.S. academic institutions. This study addresses the short- and long-term outcomes of an NCI-funded R25 short-term summer field research training program. This program is designed for MPH and Ph.D. students in cancer epidemiology and related disciplines, in international and minority settings (special populations) in a recent 7-year period. Positive short-term outcome of 73 students was measured as publishing a manuscript from the field research data and having a job in special populations. Positive long-term outcome was measured as having a post-doc position, being in a doctoral program, and/or employment in special populations at least 3 years from finishing the program. Significant factors associated with both short- and long-term success included resourcefulness of the student and compatibility of personalities and interests between the student and the on-campus and off-campus mentors. Short-term-success of students who conducted international filed research was associated with visits of the on-campus mentor to the field site. Short-term success was also associated with extent of mentorship in the field site and with long-term success. Future studies should investigate how field research sites could enhance careers of students, appropriateness of the sites for specific training competencies, and how to maximize the learning experience of students in international and minority research sites.

    We summarize a portfolio of possible field experiments on solar radiation management (SRM) and related technologies. The portfolio is intended to support analysis of potential field research related to SRM including discussions about the overall merit and risk of such research as well as mechanisms for governing such research and assessments of observational needs. The proposals were generated with contributions from leading researchers at a workshop held in March 2014 at which the proposals were critically reviewed. The proposed research dealt with three major classes of SRM proposals: marine cloud brightening, stratospheric aerosols and cirrus cloud manipulation. The proposals are summarized here along with an analysis exploring variables such as space and time scale, risk and radiative forcing. Possible gaps, biases and cross-cutting considerations are discussed. Finally, suggestions for plausible next steps in the development of a systematic research programme are presented.

    As one of the method of selecting ore, the magnetic separation method has the advantages of stable operation, simple process flow, high beneficiation efficiency and no chemical environment pollution. But the existing magnetic separator are more mechanical, the operation is not flexible, and can not change the magnetic field parameters according to the precision of the ore needed. Based on the existing magnetic separator is mechanical, the rotating magnetic field can be used for single chip microcomputer control as the research object, design and trial a rotating magnetic field processing prototype, and through the single-chip PWM pulse output to control the rotation of the magnetic field strength and rotating magnetic field speed. This method of using pure software to generate PWM pulse to control rotary magnetic field beneficiation, with higher flexibility, accuracy and lower cost, can give full play to the performance of single-chip.

To understand how much consumers search for such information online on one Internet search engine, whether they mention such information in social media and how positively they view this information. A leading Internet search engine (Google) was the main focus of the study. Google Trends and Google Adwords keyword analyses were performed for national and Californian searches between 1 August 2012 and 31 July 2013 for keywords related to 'top hospital', best hospital', and 'hospital quality', as well as for six specific hospital quality reports. Separately, a proprietary social media monitoring tool was used to investigate blog, forum, social media and traditional media mentions of, and sentiment towards, major public reports of hospital quality in California in 2012. (1) Counts of searches for keywords performed on Google; (2) counts of and (3) sentiment of mentions of public reports on social media. National Google search volume for 75 hospital quality-related terms averaged 610 700 searches per month with strong variation by keyword and by state. A commercial report (Healthgrades) was more commonly searched for nationally on Google than the federal government's Hospital Compare, which otherwise dominated quality-related search terms. Social media references in California to quality reports were generally few, and commercially produced hospital quality reports were more widely mentioned than state (Office of Statewide Healthcare Planning and Development (OSHPD)), or non-profit (CalHospitalCompare) reports. Consumers are somewhat aware of hospital quality based on Internet search activity and social media disclosures. Public stakeholders may be able to broaden their quality dissemination initiatives by advertising on Google or Twitter and using social media interactively with consumers looking

    Full Text Available Important qualitative changes were taking place in polish geodesy in last few years. It was related to application of new techniques and technologies and to introduction of European reference frames in Poland. New reference stations network ASG-EUPOS, together with Internet services which helps in precise positioning was created. It allows to fast setting up precise hybrid networks. New, accurate satellite networks became the basis of new definitions in the field of reference systems. Simultaneously arise the need of new software, which enables to execute the geodetic works in new technical conditions. Authors had an opportunity to participate in mentioned undertakings, also under the aegis of GUGiK, by creation of methods, algorithms and necessary software tools. In this way the automatic postprocessing module (APPS in POZGEO service, a part of ASG-EUPOS system came into being. It is an entirely polish product which works in Trimble environment. Universal software for transformation between PLETRF89, PL-ETRF2000, PULKOWO’42 reference systems as well as defined coordinate systems was created (TRANSPOL v. 2.06 and published as open product. An essential functional element of the program is the quasi-geoid model PL-geoid-2011, which has been elaborated by adjustment (calibration of the global quasi-geoid model EGM2008 to 570 geodetic points (satellite-leveling points.

    Surveillance of the safety of prescribed drugs after marketing approval has been secured remains fraught with complications. Formal ascertainment by providers and reporting to adverse-event registries, formal surveys by manufacturers, and mining of electronic medical records are all well-known approaches with varying degrees of difficulty, cost, and success. Novel approaches may be a useful adjunct, especially approaches that mine or sample internet-based methods such as online social networks. A novel commercial software-as-a-service data-mining product supplied by Sysomos from Datasift/Facebook was used to mine all mentions on Facebook of statins and stain-related side effects in the US in the 1-month period 9 January 2017 through 8 February 2017. A total of 4.3% of all 25,700 mentions of statins also mentioned typical stain-related side effects. Multiple methodological weaknesses stymie interpretation of this percentage, which is however not inconsistent with estimates that 5-20% of patients taking statins will experience typical side effects at some time. Future work on pharmacovigilance may be informed by this novel commercial tool, but the inability to mine the full text of a posting poses serious challenges to content categorization.

    2015-09-01

    This study examines relevant aspects about the way anthropological research data restitution has been applied in the area of health, based on data obtained from ethnographic field research conducted in Brazil and France. These experiences show that data restitution has been part of the area of research, in different forms and time frames, making it possible to extend periods spent in the field and to interact with individual respondents. This also made it possible to interact with research interlocutors and compare different points of view, adding new information and thereby enriching the research. These aspects raise important questions that require reflection, from an ethical and epistemological standpoint. One is related to the demands made on health anthropologists when they begin their field research and how they deal with these questions: how will researchers use the data they collect without worrying that this may be wrongly interpreted or used in some way to reinforce normative patterns? So, how should an anthropological debate be "translated"? Conscientious researchers will seek to validate their analysis, to discover new points of view and provoke new lines of questioning. Thus, such data should provoke reflexivity about new avenues of research and interpretations.

    Comparative effectiveness research (CER) and community- based participatory research (CBPR) are two fields of research that do not have a history of strong collaboration. However, CER and CBPR researchers could benefit from interdisciplinary collaboration to design and implement relevant, timely, action-oriented research. This commentary explores field-specific definitions of stakeholders and then outlines various roles stakeholders might play within grant-funded research. Questions such as "What stakeholders should be involved?" and "How are stakeholders involved?" are addressed. The goal of this commentary is to highlight how the expertise and experiences of CBPR investigators can enhance the field of CER and to describe strategies for encouraging stakeholder involvement in CER research through the lens of CBPR. It is recommended that a team-based approach to conducting stakeholder-engaged CER encourages multiple stakeholders and "end users" to contribute their diverse expertise to the research process and contributes to the development of research with an increased likelihood of improving patient health and healthcare. © 2013 Wiley Periodicals, Inc.

    There are a lot of research themes in the field of urban planning and related fields as mitigation of global environment change. Main theme is reduction method of CO{sub 2} gas emission as a countermeasure against global warming. Some groups research on estimation of CO{sub 2} emission caused by construction activities both in building engineering and civil engineering and also on evaluation of countermeasures. They investigate reduction of CO{sub 2} emission by fossil fuel combustion and by building materials (cement, steel and so on) production process. But we cannot use data fitted to a spatial scale of urban planning. Many researches are focused on nation wide analysis. We, BRI, make a study of {open_quotes}Research on CO{sub 2} Emission in Urban Development and the Control Technologies{close_quotes} as will be seen later at 2. (2). There are two ways of research to reduce CO{sub 2} emission caused by daily activities to urban planning field. One is research on positive utilizing of natural environment in urban areas without depending to energy consuming artificial facilities. There is a research on mitigation of heat island phenomenon for instance. The other ways are research on improvement of energy consumption effect and on reusing of wasted energy In energy consuming type urban space for instance. There s a research on promoting District Heating and Cooling (DHC) and cogeneration.

    Production of energy plants on set aside areas of peat production has risen to a subject of discussions during past few years. The field area becoming useless has been estimated to be, before the EU-membership, hundreds of thousands of hectares, 500 000 - 800 000 ha. Alternate usage will be needed for the set aside field areas because the profitability of plant cultivation is diminishing remarkable, and new possibilities for additional income are sought in Finnish farms. Research on field biomasses started in the national Bioenergy Research Programme in 1995. The number of projects was five, funded mainly by the Finnish Ministry of Agriculture and Forestry. The projects carried out in 1995 were: (1) Demonstration of the cultivation of Rape and Reed canary grass at present oil mills to fuel-oil, paper fibers and flash-pyrolysis oil as a large non-food production; (2) Cultivation of energy plants at peat production areas and the applicability of the bioenergy for different purposes; (3) Production of biomass in fields and the utilization of it for energy production; (4) Fractionation of different parts of the field plants and the development of the sorting technologies; and (5) Upgraded fuel from reed canary grass (an international task of the EU/AIR programme). In addition to these, the Agro-fiber research, funded totally by the Ministry of Agriculture and Forestry, will serve the purposes of the energy sector. The research is concentrated on the investigation of the fundamentals of the pulping applications of the field biomasses

    Nuclear research and development have been intensively pursued in West Germany by the Government and the Laender since 1955. In this period, the aims and official measures for fostering the research and use of nuclear power for peaceful purposes were laid down in four nuclear programmes. The 4th Nuclear Programme covers the period 1973 to 1976. From 1977, nuclear development became part of the energy research programme which was published by the West German Government in the spring of 1977. The basic nuclear research, however, was regarded as part of a total concept for fostering basic research (to be developed). While all the activities of research in the natural sciences and arts fostered by the West German Ministry of Research and Technology were to be co-ordinated in a more schematic form in the plan for 'Basic Research', it is the aim of the present statement to take stock of the present situation in 'Basic Nuclear Research' including the associated fields of 'Nuclear Solid Research' and 'Synchrotron Radiation', to analyse their structure, to describe the scientific aims for the next five years and to determine the total financial requirements. The basis for determining the financial programme worked out by the expert committee on 'Physical Research in the Nuclear Field' and the other committees in this field. The plans are in agreement with the medium term plan of the West German Ministry of Research and Technology (at 27.10.1977) and their contents correspond to the state of affairs at the end of 1977.

  11. Work-Identity in Ethnographic Research: Developing Field Roles in a Demanding Workplace Setting

    Directory of Open Access Journals (Sweden)

    Gunilla Jansson PhD

    2013-02-01

    Full Text Available In this article we problematize our field roles as two linguistic ethnographers who aim to study the communication and documentation practices drawn upon by care workers in elderly care facilities in Sweden. Our field roles are discussed in relation to the complex nature of care workers' knowledge and competence, which results from three different aspects of their work-identities: institutional, professional, and individual. As researchers, we found ourselves in constant dialogue with the research participants, and our field roles were continuously shaped and reshaped according to the individuals and the situations in which we became involved. Even aspects of our own identities taken into the field, such as our background and personal qualities, proved to be important in establishing good relations with the care staff. Coming closer to the participants' professional identity proved to be of utmost importance for interpreting their choices and decisions in the workplace. Identity negotiation is presented here as a constructive way of discussing ethnographic field roles in the research field.

  12. Mobile application for field data collection and query: Example from wildlife research (Invited)

    Field data collection is often used in many scientific disciplines and effective approaches rely on accurate data collection and recording. We designed a smartphone and tablet application (app) for field-collected data and tested it during a study on wildlife. The objective of our study was to determine the effectiveness of mobile applications in wildlife field research. Student software developers designed applications for mobile devices on the iOS and Android operating systems. Both platforms had similar user interactions via data entry on a touch screen using pre-programmed fields, checkboxes, drop-down menus, and keypad entry. The mobile application included features to insure collection of all measurements in the field through pop-up messages and could proof entries for valid formats. We used undergraduate student subjects to compare the duration of data recording and data entry, and the frequency of errors between the mobile application and traditional (paper) techniques. We field-tested the mobile application using an existing study on wildlife. From the field, technicians could query a database stored on a mobile device to view histories of previously captured animals. Overall, we found that because the mobile application allowed us to enter data in a digital format in the field we could eliminate timely steps to process handwritten data sheets and double-checking data entries. We estimated that, for a 2-month project, using the mobile application instead of traditional data entry and proofing reduced our total project time by 10%. To our knowledge, this is the first application developed for mobile devices for wildlife users interesting in viewing animal capture histories from the field and could be developed for use in other areas of field research.

  13. Reflections by a student and a faculty member on student-faculty collaborative geophysical field research

    Science.gov (United States)

    Bank, C.; Rotzien, J.

    2007-12-01

    More and more students and faculty engage in collaborative research. Field geophysics provides a fascinating venue, as it always contributes to interpersonal relations, usually involves off-campus work, and often allows us to meet new people and explore a different culture. Tackling an authentic research problem keeps a faculty member excited about her/his discipline, while allowing a student to engage in the process of science, follow a researcher's thoughts and contribute to a real project. The exchange of ideas and the generation of new knowledge is rewarding to the student as it facilitates her/his academic growth. Despite the obvious advantages of including students in field-based research, few students are allowed such an opportunity because of the institutional commitment in time and money that is necessary for success. Other challenges in field-based geophysical research include steep learning curves related to the use of equipment, unknown outcomes (data that is often difficult to interpret), and a true commitment to the project on the student's part. The faculty member on the other hand faces additional challenges because of the responsibility for students in the field, scheduling constraints, limited funding, and students' diverse academic goals. This presentation will be given by a faculty member and a student who have engaged in various authentic research projects. Projects ranged from afternoon lab exercises on campus (eg, microgravity survey over a tunnel on campus), course projects connected to field trips (eg, magnetic study and subsequent potential field analysis), summer research projects (eg, georadar survey of Deboullie Lake rock glacier), to year-long undergraduate thesis projects (eg, potential field studies at igneous centres of the Navajo Volcanic Field). We will present highlights of these projects, examine their pedagogical merits, and discuss the advantages and rewards we earned as well as the challenges we faced. Despite all challenges

    Approximately 53 million Americans live with a disability. For decades, the National Institutes of Health (NIH) has been conducting and supporting research to discover new ways to minimize disability and enhance the quality of life of people with disabilities. After the passage of the Americans With Disabilities Act, NIH established the National Center for Medical Rehabilitation Research, with the goal of developing and implementing a rehabilitation research agenda. Currently, 17 institutes and centers at NIH invest more than $500 million per year in rehabilitation research. Recently, the director of NIH, Francis Collins, appointed a Blue Ribbon Panel to evaluate the status of rehabilitation research across institutes and centers. As a follow-up to the work of that panel, NIH recently organized a conference, “Rehabilitation Research at NIH: Moving the Field Forward.” This report is a summary of the discussions and proposals that will help guide rehabilitation research at NIH in the near future.

    Students respond to personal connections. When K-12 science teachers are able to participate as field assistants on research projects, their students can benefit greatly from the stories, pictures, and video transmitted or brought back from the field. Teachers can translate and tailor their learning while in the field to the level of their students. Students are ';hooked' into science content by seeing their own teacher out there actually ';doing' science. The teacher is able to provide a direct content connection for the student, an avenue for understanding why ';learning this' is relevant and important. This presentation provides a case for why science teachers and researchers should collaborate as much as possible. The NSF funded PolarTREC program (Teachers and Researchers Exploring and Collaborating) is an excellent example of how to make this collaboration work. The presentation will also provide a look into how teachers can make an effective connection for their students between field science and classroom learning. Alaskan secondary science teacher Carol Scott spent a month at the Kevo Research Station in northern Finland in May/June 2013 as a PolarTREC teacher, and is translating this experience for students. She has also worked on an NSF Research Experience for Teachers grant in Prince William Sound, AK, and has successfully used this work to engage students in the classroom.

    The above-mentioned effort is to comply with the COP3 (Third Session of the Conference of the Parties to the United Nations Framework Convention on Climate Change) joint implementation clause. At this coal field, mining facilities are growing superannuated and obsolescent in the prolonged business depression, causing frequent occurrence of disasters such as gas explosions. The coal mine gas collection rate at the Kuznetsk coal field is as low as 17%, with concern for safety discouraging sufficient collection. Even the small amount of the collected gas is, in the absence of gas utilizing facilities, totally discharged into the air. For the mitigation of global warming, for mining safety, and for the establishment of a foundation for business, it is desired that coal mine methane gas collection/utilization facilities and related technologies be introduced into the coal field. Gas purging from the pits is incomplete, which is attributed to the lack of equipment capable of excavating proper-diameter bores longer than 100m for longwall mining. Ventilation also needs improvement. The research is under way on the premise that highly reliable intermediate range (300m) boring equipment and gas management technologies will be available. Collection of gas of a 30-35% concentration level at a collection rate of 40% is the target. (NEDO)

    2017-08-01

    Digital heritage comprises a broad variety of approaches and topics and involves researchers from multiple disciplines. While the use of digital methods in the text-oriented disciplines dealing with cultural heritage is widely discussed and canonized, an up-to-date investigation on cultural heritage as a scholarly field is currently missing. The extended abstract is about a three-stage investigation on standards, publications, disciplinary cultures as well as scholars in the field of digital heritage, carried out in 2016 and 2017. It includes results of a workshop-based survey involving 44 researchers, 15 qualitative interviews as well as an online survey with nearly 1000 participants. As an overall finding, a community is driven by researchers from European countries and especially Italy with a background in humanities, dealing with topics of data acquisition, data management and visualization. Moreover, conference series are most relevant for a scientific discourse, and especially EU projects set pace as most important research endeavours.

  18. Engaging High School Science Teachers in Field-Based Seismology Research: Opportunities and Challenges

    Long, M. D.

    2015-12-01

    Research experiences for secondary school science teachers have been shown to improve their students' test scores, and there is a substantial body of literature about the effectiveness of RET (Research Experience for Teachers) or SWEPT (Scientific Work Experience Programs for Teachers) programs. RET programs enjoy substantial support, and several opportunities for science teachers to engage in research currently exist. However, there are barriers to teacher participation in research projects; for example, laboratory-based projects can be time consuming and require extensive training before a participant can meaningfully engage in scientific inquiry. Field-based projects can be an effective avenue for involving teachers in research; at its best, earth science field work is a fun, highly immersive experience that meaningfully contributes to scientific research projects, and can provide a payoff that is out of proportion to a relatively small time commitment. In particular, broadband seismology deployments provide an excellent opportunity to provide teachers with field-based research experience. Such deployments are labor-intensive and require large teams, with field tasks that vary from digging holes and pouring concrete to constructing and configuring electronics systems and leveling and orienting seismometers. A recently established pilot program, known as FEST (Field Experiences for Science Teachers) is experimenting with providing one week of summer field experience for high school earth science teachers in Connecticut. Here I report on results and challenges from the first year of the program, which is funded by the NSF-CAREER program and is being run in conjunction with a temporary deployment of 15 seismometers in Connecticut, known as SEISConn (Seismic Experiment for Imaging Structure beneath Connecticut). A small group of teachers participated in a week of field work in August 2015 to deploy seismometers in northern CT; this experience followed a visit of the

    Full Text Available The duct of a robot vacuum cleaner is the length of the flow channel between the inlet of the rolling brush blower and the outlet of the vacuum blower. To cope with the pressure drop problem of the duct flow field in a robot vacuum cleaner, a method based on Pressure Implicit with Splitting of Operators (PRISO algorithm is introduced and the optimisation design of the duct flow field is implemented. Firstly, the duct structure in a robot vacuum cleaner is taken as a research object, with the computational fluid dynamics (CFD theories adopted; a three-dimensional fluid model of the duct is established by means of the FLUENT solver of the CFD software. Secondly, with the k-∊ turbulence model of three-dimensional incompressible fluid considered and the PRISO pressure modification algorithm employed, the flow field numerical simulations inside the duct of the robot vacuum cleaner are carried out. Then, the velocity vector plots on the arbitrary plane of the duct flow field are obtained. Finally, an investigation of the dynamic characteristics of the duct flow field is done and defects of the original duct flow field are analysed, the optimisation of the original flow field has then been conducted. Experimental results show that the duct flow field after optimisation can effectively reduce pressure drop, the feasibility as well as the correctness of the theoretical modelling and optimisation approaches are validated.

    1976-03-01

    Investigations on the safety of Light Water Reactors (LWR) being performed in the framework of the safety program 'Reactor Safety' are sponsored by the Bundesminister fuer Forschung und Technologie (BMFT - Secretary of State for Research and Technology). Objective of this program is to continue improving the safety of LWR, in order to minimize the risk for the environment. With grant assistance from the Bundesminister des Innern. (BMI - Secretary of State for Home Affairs) research cont racts in the field of reactor safety are being performed. Results of these projects should contribute to resolve questions arising nuclear licensing procedures. The Forschungsbetreuung (FB - research supervision department) at the Institute for Reactor Safety (IRS), as consultants to BMFT and BMI, provides information about the progress of investigations. Individual reports will be prepared and put into standard forms by the research contractors. Each report gives information on: 1) the work accomplished, 2) the results obtained, 3) the work planned to be continued. Initial reports of research projects describe in addition the purpose of the work. A BMFT-research program on the safety of Fast Breeders (Schneller Brutreaktor - SBR) is presently under discussion. In order to define several problems, investigations included in the present compilation (RS 139, 140, 143, 162) will be previously performed. (orig.) [de

    Full Text Available Hurricane Irene caused widespread and significant impacts along the U.S. east coast during 27–29 August 2011. During this period, the storm moved across eastern North Carolina and then tracked northward crossing into Long Island and western New England. Impacts included severe flooding from the mid-Atlantic states into eastern New York and western New England, widespread wind damage and power outages across a large portion of southern and central New England, and a major storm surge along portions of the Long Island coast. The objective of this study was to conduct retrospective simulations using the Advanced Research Weather Research and Forecast (WRF-ARW model in an effort to reconstruct the storm’s surface wind field during the period of 27–29 August 2011. The goal was to evaluate how to use the WRF modeling system as a tool for reconstructing the surface wind field from historical storm events to support storm surge studies. The results suggest that, with even modest data assimilation applied to these simulations, the model was able to resolve the detailed structure of the storm, the storm track, and the spatial surface wind field pattern very well. The WRF model shows real potential for being used as a tool to analyze historical storm events to support storm surge studies.

    The University of Texas Institute for Geophysics (UTIG) recognizes the value of providing educational opportunities to K-12 teachers who play a critical role in shaping the minds of young people who are the future of our science. To that end, UTIG established the "Texas Teachers in the Field" program in 2000 to formalize the participation of K-12 teachers in field programs that included UTIG scientists. In 2002, "Texas Teachers in the Field" evolved through UTIG's involvement in a University of Texas at Austin GK-12 project led by the Environmental Sciences Institute, which enabled UTIG to partner a subset of GK-12 Fellows with teachers participating in geophysical field programs. During the three years of the GK-12 project, UTIG successfully partnered four GK-12 Fellows with five K-12 teachers. The Fellows served as mentors to the teachers, as liaisons between UTIG scientists leading field programs and teachers and their students, and as resources in science, mathematics, and technology instruction. Specifically, Fellows prepared teachers and their students for the field investigations, supervised the design of individual Teacher Research Experience (TRE) projects, and helped teachers to develop standards-aligned curriculum resources related to the field program for use in their own classrooms, as well as broader distribution. Although all but one TRE occurred during the school year, Texas school districts and principals were willing to release teachers to participate because the experience and destinations were so extraordinary (i.e., a land-based program in Tierra del Fuego, Argentina; and research cruises to the Southeast Caribbean Sea and Hess Deep in the Pacific Ocean) and carried opportunities to work with scientists from around the world. This exceptional collaboration of GK-12 Fellows, K-12 teachers and research scientists enriches K-12 student learning and promotes greater enthusiasm for science. The level of mentoring, preparation and follow-up provided

    Mankind has been expressing the breeding topic for thousands of years. Reproduction is the primary instinct of human beings and it is a social, cultural, medical issue. Demographic infertility is one of them, which is defined infertility as the inability to become pregnant with a live birth, within five years of regular sexual contact based upon a consistent union status in marriage maintaining a desire for a child with the lack of contraceptive use and non-lactating. A first mentions about infertility and surrogacy is discovered on a 4000-year-old clay tablet of marriage contract belonging to the Assyrian period exhibited at Istanbul Archeology Museum in Turkey. In conclusion, there are many different ways to solve infertility problems like surrogacy as mentioned even 4000 years ago in this Assyrian clay tablet of marriage contract as the first time in the literature. Medical treatments in relation to human infertility will continue to be the focus of social and cultural debates. Hence, more legislation and regulation will come in many countries to control the unauthorized exploitation of the patient.

    Full Text Available Although ethnochoreology and ethnomusicology as related academic disciplines have decades-long histories, reviewing and redefining their basic epistemological and methodological principles remained one of the main focuses of disciplinary discussion. Most ethnochoreologists and ethnomusicologist agrees that “field” work (in all its traditional and contemporary forms remains an essential and constitutive quality of their research and disciplinary fields. The inherent interdisciplinary networking of ethnochoreology and ethnomusicology starts from the theoretical premise that the relationship between the kinetic and musical components of dance is not only unbreakable, but also interactive, and that complex and dynamic manifestations of dance performances represents an expressive medium through which a particular community constructs and represents itself. Since the importance of the individual experience of researchers has been ephasized during the last few decades, a comprehensive method of participant observation remains a central and unifying aspect of fieldwork, both in ethnochoreology and ethnomusicology. Based on field research of musical and dance practices of the village of Svinica (Sviniţa in Romania, this paper reviews the application and combination of various methods of field research (observation, participation in the performance process, filming, interviews and writing field notes as the primary tools for the acquisition and shaping of scientific knowledge about dance and music. Issues that will be discussed include the following questions: What are the advantages of personal kinetic/auditory experience during simultaneous perception of dance movement and dance music? How can different methods of field research be combined in order to improve cognitive processes? Are there border areas between ethnochoreological and ethnomusicological fieldwork? Does the variety of methods of field research represents a weakness of the

    Understanding emerging areas of a multidisciplinary research field is crucial for researchers, policymakers and other stakeholders. For them a knowledge structure based on longitudinal bibliographic data can be an effective instrument. But with the vast amount of available online information it is often hard to understand the knowledge structure for data. In this paper, we present a novel approach for retrieving online bibliographic data and propose a framework for exploring knowledge structure. We also present several longitudinal analyses to interpret and visualize the last 20 years of published obesity research data.

    In this paper an overview is given of the European Union (EU) Euratom research conducted through shared cost and concerted actions in the field of plant life management. After a general introduction on the organisation of the research framework programmes the achievements of the 4th framework programme (FP-4/1994-1998) and the activities under the 5th framework programme (FP-5/1999-2002) in the field of plant life management are presented and discussed in detail. Besides technological safety requirements, socio-economic aspects are becoming increasingly important due to the level of public and political acceptance and to the economic pressure of deregulated electricity markets. It is shown that research conducted in the Euratom framework may contribute to meet these requirements, thereby maintaining nuclear power as a competitive and sustainable option for the energy policy of the European Union.

    Research to improve productivity on an ongoing basis in the agricultural sector is essential to ensure and guarantee the country's food security. Malaysian Nuclear Agency, agricultural research had begun in 1981 in which the focus of research is related to mutation breeding, irradiation and the use of isotopes in the study of plant nutrition. Although projects agricultural research carried out based on nuclear technology, other information relating to agricultural research such as agronomy, plant physiology, meteorology and ecology, soil characteristics and water is essential to obtain the understanding and research results that are relevant and significant. Data acquisition for other aspects also need a system and a modern and efficient equipment, in accordance with current technological developments. This paper describes the use, function and capabilities of the existing field equipment available in Agrotechnology and Biosciences Division, Malaysian Nuclear Agency in acquiring data related to weather, measurement and control of ground water, soil nutrients assessment and monitoring of plant physiology. The latest technological developments in sensor technology, computer technology and communication is very helpful in getting data more easily, quickly and accurately. Equipment and the data obtained is also likely to be used by researchers in other fields in Nuclear Malaysia. (author)

    1993-01-01

    Increasingly, citizens of Washington State are expressing their concerns about possible adverse health effects of electric and magnetic fields (EMF) from electric utility power systems. A number of legislative proposals over the past several years have prompted governmental officials to evaluate available options for reducing electric and magnetic field strengths surrounding these systems (with a concentration on magnetic fields) or otherwise manage public exposure to power lines by increasing land use controls and setbacks for new development. Unsuccessful proposals brought before the Washington Legislature include 2 mG magnetic field limits for new transmission lines at the right-of-way edge; a temporary moratorium on transmission construction; requirements for providing public information on EMF; and expansion of the role of state governmental agencies in transmission siting and design. A successful Whatcom County initiative limits the voltage of new transmission to 115 kV in all but industrial land use zones, an action likely to have an unintended outcome of increasing magnetic fields in some areas. It is clear that better communication is needed about possible options for EMF management, costs and consequences, despite the fact scientific evidence on the existence of human health effects is inconclusive. This paper describes the work that Washington State undertook in 1990-92 in response to Engrossed Substitute Senate Bill 6771 establishing the Electric Transmission Research Needs Task Force. The Task Force was directed to report to the Legislature on possible exposure reduction methods; recommending engineering research that could lead to more effective approaches in the future

  17. A National Collaborative for Building the Field of Childhood Obesity Research.

    Science.gov (United States)

    2018-03-01

    Rising rates of childhood obesity over the past 2 decades have spurred a number of public- and private-sector initiatives aimed at halting or even reversing this trend. Recognizing common interests in this issue, the Centers for Disease Control and Prevention, NIH, and the Robert Wood Johnson Foundation began conversations about creating a formal collaboration aimed at accelerating efforts to address childhood obesity by coordinating research agendas and providing support for evidence-building activities. The National Collaborative on Childhood Obesity Research (NCCOR) was launched in February 2009, and the U.S. Department of Agriculture joined in 2010. Using the model provided by other previously successful collaborations, such as the Youth Tobacco Cessation Collaborative, NCCOR has emphasized several principles suggested by Petrovich as key elements for successful partnerships: (1) delineate a common purpose by identifying key knowledge gaps in the field; (2) create a shared identity around that common purpose; (3) develop structures for democratic and respectful collaboration so as to strategically coordinate efforts for maximum national impact; (4) identify effective leaders capable of articulating challenges in the field and inspiring a commitment of minds and the resolve to address identified needs; (5) facilitate continuous knowledge exchange and synthesis to keep the field informed; and (6) support assessment of progress and feedback loops for ensuring continual progress. This paper examines how NCCOR has used these principles to help build the field of research, evaluation, and surveillance for childhood obesity prevention and management. Published by Elsevier Inc.

    2005-12-01

    Over the past eight years, 18 undergraduate students from 12 U.S. and Costa Rican universities and colleges have participated in field research projects investigating coastal tectonics on the Nicoya Peninsula, Costa Rica. These projects have been organized around two different models: 1) a month-long "field camp" with 10 students and 5 project faculty (Keck Geology Consortium Project, 1998), and 2) several two-week field projects with 1-3 students and one faculty advisor (Cal Poly Pomona University and Trinity University). Under the direction of the authors, each of these projects has been carefully designed to provide a new piece to a larger research puzzle. The Nicoya Peninsula lies along Costa Rica's northern Pacific coast inboard of the Middle America Trench where the Cocos and Caribbean plates converge at 10 cm/yr. In 1950, the peninsula was shaken by a ~M 7.7 subduction earthquake that produced widespread damage and 0.5-1.0 m of coseismic coastal uplift. With a large slip deficit since 1950, the Nicoya Peninsula is viewed as a high-potential seismic gap. Field study of uplifted Quaternary marine terraces along the Nicoya coastline provides undergraduate students with a unique opportunity to examine rapid forearc deformation related to large subduction earthquakes. The field research conducted by each of these students provides the basis for a senior thesis at their home institution. In most cases, the students have focused their individual work on separate, but adjacent field areas. Collectively, each of these projects has generated significant data that contribute toward of an ongoing investigation of fore arc tectonics and subduction cycle earthquakes along the Costa Rican Pacific margin.

    2011-08-01

    The main objective of the present study was to classify doctoral programs with Quality Mention in Psychology based on their scientific productivity. For this purpose, articles in the Web of Science published by professors teaching in these doctoral programs were analyzed. In addition, we analyzed scientific journals in which these professors tend to publish more papers and the evolution in the number of papers published until 2009. Results showed that the most productive doctoral program was the Neurosciences program at the University of Oviedo. This program showed a ratio of 40 articles--published in journals included in Journal Citation Reports--by each professor. In contrast, other programs did not reach a ratio of 10 articles per professor. Regarding journals, results showed that 9 out of the 20 most popular journals are Hispanic and a gradual increase in the number of published papers was also observed. Lastly, results and implications for quality assessment are discussed.

    Full Text Available The overall dynamic development of operational research in various fields of human activities urges the need for a clearer and mathematically more explicit classification of its methods. This need is also very urgent in the field of defense, particularly because of the complications of modern conflicts, as well as of new security requirements. One of the possible classifications of methods based on the theory of games as a mathematical model for solving conflict situations is presented in this paper. The connections between methods and their mathematical description are underlined.

  3. Electric Field Encephalography as a tool for functional brain research: a modeling study.

    Directory of Open Access Journals (Sweden)

    Yury Petrov

    Full Text Available We introduce the notion of Electric Field Encephalography (EFEG based on measuring electric fields of the brain and demonstrate, using computer modeling, that given the appropriate electric field sensors this technique may have significant advantages over the current EEG technique. Unlike EEG, EFEG can be used to measure brain activity in a contactless and reference-free manner at significant distances from the head surface. Principal component analysis using simulated cortical sources demonstrated that electric field sensors positioned 3 cm away from the scalp and characterized by the same signal-to-noise ratio as EEG sensors provided the same number of uncorrelated signals as scalp EEG. When positioned on the scalp, EFEG sensors provided 2-3 times more uncorrelated signals. This significant increase in the number of uncorrelated signals can be used for more accurate assessment of brain states for non-invasive brain-computer interfaces and neurofeedback applications. It also may lead to major improvements in source localization precision. Source localization simulations for the spherical and Boundary Element Method (BEM head models demonstrated that the localization errors are reduced two-fold when using electric fields instead of electric potentials. We have identified several techniques that could be adapted for the measurement of the electric field vector required for EFEG and anticipate that this study will stimulate new experimental approaches to utilize this new tool for functional brain research.

  4. Field research internships: Why they impact students' decisions to major in the geosciences

    2017-12-01

    Although internships have been shown to retain geoscience students, little research has been done on what components of research or field experiences during an internship impact students' decisions to major in the geosciences. We created and led a short, two-week field-based internship for 5 introductory-level students to conduct research and create a poster to present their results. In addition to the two professors leading the internship and the 5 interns, there were 2 masters students and 1 community college student who were returning to the field area to collect data for their own projects. These students also helped to guide and mentor the interns. The interns were diverse in many aspects: 3 were female, 2 were non-white, 3 were community college students (1 4YC student was a transfer), 2 were first-generation college students, and their ages ranged from 18 to 33. Based on our evaluation, we found that the research experience increased students' self-efficacy in the geosciences through various means, increased their connection with mentors and other individuals who could serve as resources, gave them a sense of belonging to the geoscience culture, increased their knowledge of geoscience career paths and expectations, helped them make connections with Earth, and maintained their interest. These factors have been described in the literature as leading to retention, and we propose that field-based internships are successful for recruitment or retention in the geosciences because they influence so many of these affective and cognitive components at once. In particular, the social aspect of internships plays a fundamental role in their success because many of these factors require close and sustained interactions with other people. An implication of this research is that these affective components, including social ones, should be explicitly considered in the design and implementation of internships to best serve as a recruitment and retention strategy.

    2017-03-01

    Full Text Available This paper’s intention is to share some of the main results of two field-based research projects regarding assisted human reproduction practices in Argentina. Both projects have been developed in a dynamic legislative context involving medical coverage regulation, parentage determination and the right to know one's origins for children born with third party genetic material. Also, in this context, the Draft Civil and Commercial Code reform introduced two figures that were then removed in the parliamentary debate: post mortem fertilization and surrogate motherhood. All these issues concerning the use of assisted human reproduction challenge the legal field and are addressed in these research projects, one of them more from an explorative perspective and the other from a qualitative one. Therefore, this article aims to introduce some of the measured variables and the findings obtained to serve as relevant contributions to achieve a more appropriate legislation according with the medical and social reality.

    Oceanographic research cruises are complex affairs, typically requiring an extensive effort to secure the funding, plan the experiment, and mobilize the field party. Yet cruises are not typically published online as first-class digital objects with persistent, citable identifiers linked to the scientific literature. The Rolling Deck to Repository (R2R; info@rvdata.us) program maintains a master catalog of oceanographic cruises for the United States research fleet, currently documenting over 6,000 expeditions on 37 active and retired vessels. In 2015, R2R started routinely publishing a Digital Object Identifier (DOI) for each completed cruise. Cruise DOIs, in turn, are linked to related persistent identifiers where available including the Open Researcher and Contributor ID (ORCID) for members of the science party, the International Geo Sample Number (IGSN) for physical specimens collected during the cruise, the Open Funder Registry (FundRef) codes that supported the experiment, and additional DOIs for datasets, journal articles, and other products resulting from the cruise. Publishing a persistent identifier for each field expedition will facilitate interoperability between the many different repositories that hold research products from cruises; will provide credit to the investigators who secured the funding and carried out the experiment; and will facilitate the gathering of fleet-wide altmetrics that demonstrate the broad impact of oceanographic research.

    The British Service Dhaulagiri Research Expedition (BSDMRE) took place from 27 March to 31 May 2016. The expedition involved 129 personnel, with voluntary participation in nine different study protocols. Studies were conducted in three research camps established at 3600, 4600 and 5140 m and involved taking and storing blood samples, cardiac echocardiography and investigations involving a balance plate. Research in this remote environment requires careful planning in order to provide a robust and resilient power plan. In this paper we aim to report the rationale for the choices we made in terms of power supply, the equipment used and potential military applicability. This is a descriptive account from the expedition members involved in planning and conducting the medical research. Power calculations were used to determine estimates of requirement prior to the expedition. The primary sources used to generate power were internal combustion engine (via petrol fuelled electric generators) and solar panels. Having been generated, power was stored using lithium-ion batteries. Special consideration was given to the storage of samples taken in the field, for which electric freezers and dry shippers were used. All equipment used functioned well during the expedition, with the challenges of altitude, temperature and transport all overcome due to extensive prior planning. Power was successfully generated, stored and delivered during the BSDMRE, allowing extensive medical research to be undertaken. The challenges faced and overcome are directly applicable to delivering military medical care in austere environments, and lessons learnt can help with the planning and delivery of future operations, training exercises or expeditions. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    2015-12-01

    There are two primary strategies that I have pursued over the last decade to engage the media, policy makers, and public; after two decades of typical scientific publication methods. An effective method to engage the media with our ongoing 32 year glacier field research program has been to invite media members to join us in the field. From climate videographers to traditional reporters we have had a member of the media with us in nine of the last ten field seasons; two in 2015. The resulting stories have led to several awards for the journalists and an ongoing relationship with our research program. The second part of this science research communication strategy is to have readily available material on specific topics for the media to utilize; this requires social media outreach. The primary outlet media find is the AGU Blog: From a Glacier's Perspective. This blog pubishes two articles a week on a specific glacier's response to climate change. The blog yields on average a media contact on every fourth blog post in 2015. The contacts revolve around specific local glacier information published on the blog. The goal of each blog post is to tell a story about how each glacier is impacted by climate change.

    After conducting the intensive research on the distribution of fluid's velocity and biochemical reactions in the membrane bioreactor (MBR), this paper introduces the use of the mass-transfer differential equation to simulate the distribution of the chemical oxygen demand (COD) concentration in MBR membrane pool. The solutions are as follows: first, use computational fluid dynamics to establish a flow control equation model of the fluid in MBR membrane pool; second, calculate this model by adopting direct numerical simulation to get the velocity field of the fluid in membrane pool; third, combine the data of velocity field to establish mass-transfer differential equation model for the concentration field in MBR membrane pool, and use Seidel iteration method to solve the equation model; last but not least, substitute the real factory data into the velocity and concentration field model to calculate simulation results, and use visualization software Tecplot to display the results. Finally by analyzing the nephogram of COD concentration distribution, it can be found that the simulation result conforms the distribution rule of the COD's concentration in real membrane pool, and the mass-transfer phenomenon can be affected by the velocity field of the fluid in membrane pool. The simulation results of this paper have certain reference value for the design optimization of the real MBR system.

    Doubt about the relevance, appropriateness and transparency of peer review has promoted the use of citation metrics as a viable adjunct or alternative in the assessment of research impact. It is also commonly acknowledged that research metrics will not replace peer review unless they are shown to correspond with the assessment of peers. This paper evaluates the relationship between researchers' influence as evaluated by their peers and various citation metrics representing different aspects of research output in 6 fields of public health in Australia. For four fields, the results showed a modest positive correlation between different research metrics and peer assessments of research influence. However, for two fields, tobacco and injury, negative or no correlations were found. This suggests a peer understanding of research influence within these fields differed from visibility in the mainstream, peer-reviewed scientific literature. This research therefore recommends the use of both peer review and metrics in a combined approach in assessing research influence. Future research evaluation frameworks intent on incorporating metrics should first analyse each field closely to determine what measures of research influence are valued highly by members of that research community. This will aid the development of comprehensive and relevant frameworks with which to fairly and transparently distribute research funds or approve promotion applications. PMID:21494691

    Full Text Available In this research from the vantage point of Practical Theology, the author focusses on the importance and the possible value of the concept of cognition for further research. The philosophical roots of the concepts of knowledge and understanding are highlighted in a qualitative manner by means of a short selection from the insights of philosophers from the era of the Greek Philosophy to the nineteenth century. The insights of Plato, Aristotle, Thomas Aquinas, Descartes and Kant are utilised. The purpose was to indicate the importance of the concepts of knowing and cognition from an early stage. Research from the field of cognitive science also received attention in this research. The purpose of this discussion is to indicate that cognition is not a mere intellectual activity. Cognition is important in the processes of perspective-making and moral choices. Cognitive distortions could possibly endanger people�s ability to have the right cognition about people, events and life itself. The concept of phronesis, as the concept that comes the nearest to the essence of cognition, is also investigated from the vantage point of Philippians 2:5 and Romans 12:3. Wisdom thinking is really important in research on the acts of people from a practical theological vantage point. Cognition must be regarded as people�s attempt to make sense out what they already know and also out of what they are observing. In the final part of the article, fields for possible further investigation are highlighted in order to make the statement that practical theologians can consider the fact to reclaim the field of investigation on cognition in further research. The importance of cognition for liturgy, homiletics, pastoral care and youth ministry is indicated.Intradisciplinary and/or interdisciplinary implications: This article is undertaken from a practical theological vantage point in order to highlight the importance of the concept of cognition for further research.

  1. Equality adds quality: On upgrading higher education and research in the field of law

    Directory of Open Access Journals (Sweden)

    2017-01-01

    Full Text Available Much has been attempted, and many projects are still underway aimed at achieving equality in higher education and research. Today, the key argument to demand and support the integration of gender in academia is that equality is indeed about the quality on which academic work is supposed to be based. Although more or less national political, social and cultural contexts matter as much as academic environments, regarding higher education and research, the integration of gender into the field of law seems particularly interesting. Faculties of law enjoy a certain standing and status, are closely connected to power and politics, and are likely to feature resistance to equality efforts, both in the law itself and in the curriculum and research agenda. However, a multidimensional, intersectional gender analysis helps to reframe cases and doctrines, rulings and regulations far beyond the law that evidently affects women, which the headscarf controversies illustrate. In addition to gender competence, team diversity is a procedural device for success, and non-discrimination is a key requirement when diversity is meant to work. After all, such efforts - to expose bias and educate about gender in an academic field, to insist and integrate it continuously, and to not only demand but also do it - produce quality. Thus, gender equality is crucial for the achievement of the best possible results in higher education and research.

  2. On the bibliometric coordinates of four different research fields in Geography.

    Gorraiz, Juan; Gumpenberger, Christian; Glade, Thomas

    This study is a bibliometric analysis of the highly complex research discipline Geography. In order to identify the most popular and most cited publication channels, to reveal publication strategies, and to analyse the discipline's coverage within publications, the three main data sources for citation analyses, namely Web of Science, Scopus and Google Scholar, have been utilized. This study is based on publication data collected for four individual evaluation exercises performed at the University of Vienna and related to four different subfields: Geoecology, Social and Economic Geography, Demography and Population Geography, and Economic Geography. The results show very heterogeneous and individual publication strategies, even in the same research fields. Monographs, journal articles and book chapters are the most cited document types. Differences between research fields more related to the natural sciences than to the social sciences are clearly visible, but less considerable when taking into account the higher number of co-authors. General publication strategies seem to be established for both natural science and social sciences, however, with significant differences. While in natural science mainly publications in international peer-reviewed scientific journals matter, the focus in social sciences is rather on book chapters, reports and monographs. Although an "iceberg citation model" is suggested, citation analyses for monographs, book chapters and reports should be conducted separately and should include complementary data sources, such as Google Scholar, in order to enhance the coverage and to improve the quality of the visibility and impact analyses. This is particularly important for social sciences related research within Geography.

    The breadth and depth of biomedical literature are increasing year upon year. To keep abreast of these increases, FlyBase, a database for Drosophila genomic and genetic information, is constantly exploring new ways to mine the published literature to increase the efficiency and accuracy of manual curation and to automate some aspects, such as triaging and entity extraction. Toward this end, we present the 'tagtog' system, a web-based annotation framework that can be used to mark up biological entities (such as genes) and concepts (such as Gene Ontology terms) in full-text articles. tagtog leverages manual user annotation in combination with automatic machine-learned annotation to provide accurate identification of gene symbols and gene names. As part of the BioCreative IV Interactive Annotation Task, FlyBase has used tagtog to identify and extract mentions of Drosophila melanogaster gene symbols and names in full-text biomedical articles from the PLOS stable of journals. We show here the results of three experiments with different sized corpora and assess gene recognition performance and curation speed. We conclude that tagtog-named entity recognition improves with a larger corpus and that tagtog-assisted curation is quicker than manual curation. DATABASE URL: www.tagtog.net, www.flybase.org.

    To develop and validate a method for automatically quantifying the scientific quality and sensationalism of individual news records. After retrieving 163,433 news records mentioning the Severe Acute Respiratory Syndrome (SARS) and H1N1 pandemics, a maximum entropy model for inductive machine learning was used to identify relationships among 500 randomly sampled news records that correlated with systematic human assessments of their scientific quality and sensationalism. These relationships were then computationally applied to automatically classify 10,000 additional randomly sampled news records. The model was validated by randomly sampling 200 records and comparing human assessments of them to the computer assessments. The computer model correctly assessed the relevance of 86% of news records, the quality of 65% of records, and the sensationalism of 73% of records, as compared to human assessments. Overall, the scientific quality of SARS and H1N1 news media coverage had potentially important shortcomings, but coverage was not too sensationalizing. Coverage slightly improved between the two pandemics. Automated methods can evaluate news records faster, cheaper, and possibly better than humans. The specific procedure implemented in this study can at the very least identify subsets of news records that are far more likely to have particular scientific and discursive qualities.

    The manipulation of unsealed sources in biomedical research involves significant risk of radioactive contamination. the aim of this study has been to analyze the radioactive contamination occurring in the field of biomedical research, assessing its magnitude, identifying the equipment that can be contaminated with higher probability and monitoring the evolution of the contaminations production taking into account the radioisotopes and the activities uses, and the radiation protection control applied. The data used for this study correspond to a very lengthy period of time and it have been collected in the radioactive facility, of the Centro Nacional de Biotecnologia (CSIC), a very large biological research centre that can be used perfectly as a reference for this area. The results obtained show a gradual and significant decrease in the incidence of the radioactive contamination. This is due to the optimization of radiation protection standards applied and the implementation or a systematic operational radiation protection program. (Author) 13 refs.

    A is for anchoring the delivery of your research to your audience in a standard-aligned curriculum. B is for BGAN Satellite Communication System assisting in delivering real-time authentic media. C is for a collaborative online learning environment to engage learners" Z is for the peaceful sleep you will get once your program is up and running! As part of Team GoNorth! (http://www.PolarHusky.com) it is our job to deliver adventure learning. We set out to do this back when the computer was a 4-foot, 50-lb box powered by a hand-crank where one would have a window of ten minutes in a 24-hour period to catch the satellite (before Al Gore created the Internet!). Every year we review the quantum leaps in what is now possible from the field and in the classroom, and over the years we have wrestled technical issues, solutions and numerous re-structures in the process of our of curriculum development. With this presentation we will provide some basic ABC's on how you can remained focused on your research, yet deliver an adventure learning program for learners to investigate real-world issues within your scientific research. Our scales are most likely different. The volume of our curriculum is an annual production of 4-500 pages to be used from Kindergarden through 12th grade around the world. The framework of our online learning environment must be able to supports millions of users at a time. "In the field" means on a a 3-4 month dogsled expedition - so sending out our live updates involve thawing out the computers and setting up the satellite communication system to work in a ground blizzard! But regardless of the scope and location of your field research, you can probably build on some of our experiences in the planning of an upcoming adventure learning program to engage learners of all or any ages in your scientific explorations!

  9. Mixed-field GCR Simulations for Radiobiological Research using Ground Based Accelerators

    Science.gov (United States)

    Kim, Myung-Hee Y.; Rusek, Adam; Cucinotta, Francis

    Space radiation is comprised of a large number of particle types and energies, which have differential ionization power from high energy protons to high charge and energy (HZE) particles and secondary neutrons produced by galactic cosmic rays (GCR). Ground based accelerators such as the NASA Space Radiation Laboratory (NSRL) at Brookhaven National Laboratory (BNL) are used to simulate space radiation for radiobiology research and dosimetry, electronics parts, and shielding testing using mono-energetic beams for single ion species. As a tool to support research on new risk assessment models, we have developed a stochastic model of heavy ion beams and space radiation effects, the GCR Event-based Risk Model computer code (GERMcode). For radiobiological research on mixed-field space radiation, a new GCR simulator at NSRL is proposed. The NSRL-GCR simulator, which implements the rapid switching mode and the higher energy beam extraction to 1.5 GeV/u, can integrate multiple ions into a single simulation to create GCR Z-spectrum in major energy bins. After considering the GCR environment and energy limitations of NSRL, a GCR reference field is proposed after extensive simulation studies using the GERMcode. The GCR reference field is shown to reproduce the Z and LET spectra of GCR behind shielding within 20 percents accuracy compared to simulated full GCR environments behind shielding. A major challenge for space radiobiology research is to consider chronic GCR exposure of up to 3-years in relation to simulations with cell and animal models of human risks. We discuss possible approaches to map important biological time scales in experimental models using ground-based simulation with extended exposure of up to a few weeks and fractionation approaches at a GCR simulator.

  10. Exploring the use of storytelling in quantitative research fields using a multiple case study method

    Matthews, Lori N. Hamlet

    The purpose of this study was to explore the emerging use of storytelling in quantitative research fields. The focus was not on examining storytelling in research, but rather how stories are used in various ways within the social context of quantitative research environments. In-depth interviews were conducted with seven professionals who had experience using storytelling in their work and my personal experience with the subject matter was also used as a source of data according to the notion of researcher-as-instrument. This study is qualitative in nature and is guided by two supporting theoretical frameworks, the sociological perspective and narrative inquiry. A multiple case study methodology was used to gain insight about why participants decided to use stories or storytelling in a quantitative research environment that may not be traditionally open to such methods. This study also attempted to identify how storytelling can strengthen or supplement existing research, as well as what value stories can provide to the practice of research in general. Five thematic findings emerged from the data and were grouped under two headings, "Experiencing Research" and "Story Work." The themes were found to be consistent with four main theoretical functions of storytelling identified in existing scholarly literature: (a) sense-making; (b) meaning-making; (c) culture; and (d) communal function. The five thematic themes that emerged from this study and were consistent with the existing literature include: (a) social context; (b) quantitative versus qualitative; (c) we think and learn in terms of stories; (d) stories tie experiences together; and (e) making sense and meaning. Recommendations are offered in the form of implications for various social contexts and topics for further research are presented as well.

    The aim of this study was to reveal research hotspots in the field of regional health information networks (RHINs) and use visualization techniques to explore their evolution over time and differences between countries. We conducted a literature review for a 50-year period and compared the prevalence of certain index terms during the periods 1963-1993 and 1994-2014 and in six countries. We applied keyword frequency analysis, keyword co-occurrence analysis, multidimensional scaling analysis, and network visualization technology. The total number of keywords was found to increase with time. From 1994 to 2014, the research priorities shifted from hospital planning to community health planning. The number of keywords reflecting information-based research increased. The density of the knowledge network increased significantly, and partial keywords condensed into knowledge groups. All six countries focus on keywords including Information Systems; Telemedicine; Information Service; Medical Records Systems, Computerized; Internet; etc.; however, the level of development and some research priorities are different. RHIN research has generally increased in popularity over the past 50 years. The research hotspots are evolving and are at different levels of development in different countries. Knowledge network mapping and perceptual maps provide useful information for scholars, managers, and policy-makers.

    2017-03-01

    Augmentative and alternative communication (AAC) social media research is relatively new, and is built on a foundation of research on use of the Internet and social media by people with communication disabilities. Although the field is expanding to include a range of people who use AAC, there are limitations and gaps in research that will need to be addressed in order to keep pace with the rapid evolution of social media connectivity in assistive communication technologies. In this paper, we consider the aims, scope, and methodologies of AAC social media research, with a focus on social network sites. Lack of detailed attention to specific social network sites and little use of social media data limits the extent to which findings can be confirmed. Increased use of social media data across a range of platforms, including Instagram and YouTube, would provide important insights into the lives of people who use AAC and the ways in which they and their supporters use social media. New directions for AAC social media research are presented in line with those discussed at the social media research symposium at the International Society for Augmentative and Alternative Communication in Toronto, Canada, on August 12, 2016.

    During summers of 2007 and 2008 a series of International University Courses on Permafrost (IUCP) were conducted in West Siberia, Russia. Courses were organized as part of the International Permafrost Association (IPA) International Polar Year activities. The North of West Siberia region was selected to represent diverse permafrost, climatic and landscape conditions. The courses were jointly organized by the Moscow State University (MSU) and the Tumen' Oil and Gas University (TOGU) with the help from German and U.S. institutions. The program attracted undergraduate and graduate students with diverse interests and backgrounds from Germany, Russia and the U.S. and involved instructors specializing in different aspects of permafrost research. Courses were designed to address three major topics of permafrost-related research: a) permafrost environments characteristic of the discontinuous and continuous zones; b) field instrumentation and techniques; c) permafrost engineering and problems of development in permafrost regions. Methodologically, courses consisted of systematic permafrost investigations at long-term monitoring sites and survey-type expeditions. Systematic, process-based investigations were conducted at a network of sites which constitute the TEPO established by TOGU in collaboration with the gas company NadymGasProm. The observation complex includes an array of 30-m deep boreholes equipped with automatic data collection systems and representing characteristic permafrost landscapes of West Siberia. Boreholes are complemented by sites for snow cover, vegetation, soil, ground ice, and geomorphologic investigations. As part of student research activities, four new Circumpolar Active Layer Monitoring (CALM) sites were established in proximity to boreholes for monitoring spatial distribution and long-term dynamic of the active layer. New sites represent diverse landscapes characteristic of the West Siberian previously underrepresented in the CALM network

  17. [Conceptual and methodological issues involved in the research field of diagnostic reasoning].

    The psychopathological field is crossed by dilemmas that put in question its methodological, conceptual and philosophical filiations. Since the early works of Ey and Jaspers until recent work of Berrios it has been in question the position psychopathology has in the field of medicine in general, and in the field of psychiatry in particular, especially if it should follow the principles of natural science or if it has an autonomous position between them. This debate has led to two opposing positions facing two different models of psychopathology: the biomedical model and the socio-constructionist model. In this work it is proposed to review the scope and difficulties involved in each model following two central axes: diagnostic reasoning and mental illness conceptual problem. Later, as a synthesis of the analysis proposed they are identified central concepts of each model that could allow the development of a hybrid model in psychopathology; in between them the comprehensive framework employed in symptoms recognition and the social component that characterizes it are highlighted. As a conclusion, these concepts are proposed as central aspects for conceptual and methodological clarification of the research field of diagnostic reasoning in psychopathology.

    Full Text Available In this study, we used the approach of topic modeling to uncover the possible structure of research topics in the field of Informetrics, to explore the distribution of the topics over years, and to compare the core journals. In order to infer the structure of the topics in the field, the data of the papers published in the Journal of Informetricsand Scientometrics during 2007 to 2013 are retrieved from the database of the Web of Science as input of the approach of topic modeling. The results of this study show that when the number of topics was set to 10, the topic model has the smallest perplexity. Although data scopes and analysis methodsare different to previous studies, the generating topics of this study are consistent with those results produced by analyses of experts. Empirical case studies and measurements of bibliometric indicators were concerned important in every year during the whole analytic period, and the field was increasing stability. Both the two core journals broadly paid more attention to all of the topics in the field of Informetrics. The Journal of Informetricsput particular emphasis on construction and applications ofbibliometric indicators and Scientometrics focused on the evaluation and the factors of productivity of countries, institutions, domains, and journals.

    This annual report describes the background of the Deep Vadose Zone-Applied Field Research Initiative, and some of the programmatic approaches and transformational technologies in groundwater and deep vadose zone remediation developed during fiscal year 2011. The Department of Energy (DOE) Office of Technology Innovation and Development's (OTID) mission is to transform science into viable solutions for environmental cleanup. In 2010, OTID developed the Impact Plan, Science and Technology to Reduce the Life Cycle Cost of Closure to outline the benefits of research and development of the lifecycle cost of cleanup across the DOE complex. This plan outlines OTID's ability to reduce by $50 billion, the $200 billion life-cycle cost in waste processing, groundwater and soil, nuclear materials, and deactivation and decommissioning. The projected life-cycle costs and return on investment are based on actual savings realized from technology innovation, development, and insertion into remedial strategies and schedules at the Fernald, Mound, and Ashtabula sites. To achieve our goals, OTID developed Applied Field Research Initiatives to facilitate and accelerate collaborative development and implementation of new tools and approaches that reduce risk, cost and time for site closure. The primary mission of the Deep Vadose Zone-Applied Field Research Initiative (DVZ-AFRI) is to protect our nation's water resources, keeping them clean and safe for future generations. The DVZ-AFRI was established for the DOE to develop effective, science-based solutions for remediating, characterizing, monitoring, and predicting the behavior and fate of deep vadose zone contamination. Subsurface contaminants include radionuclides, metals, organics, and liquid waste that originated from various sources, including legacy waste from the nation's nuclear weapons complexes. The DVZ-AFRI project team is translating strategy into action by working to solve these complex challenges in a collaborative

    Full Text Available Surface irrigation, such as flood or furrow, is the predominant form of irrigation in California for agronomic crops. Compared to other irrigation methods, however, it is inefficient in terms of water use; large quantities of water, instead of being used for crop production, are lost to excess deep percolation and tail runoff. In surface-irrigated fields, irrigators commonly cut off the inflow of water when the water advance reaches a familiar or convenient location downfield, but this experience-based strategy has not been very successful in reducing the tail runoff water. Our study compared conventional cutoff practices to a retroactively applied model-based cutoff method in four commercially producing alfalfa fields in Northern California, and evaluated the model using a simple sensor system for practical application in typical alfalfa fields. These field tests illustrated that the model can be used to reduce tail runoff in typical surface-irrigated fields, and using it with a wireless sensor system saves time and labor as well as water.

  5. A comprehensive analysis of Italian web pages mentioning squalene-based influenza vaccine adjuvants reveals a high prevalence of misinformation.

    2018-04-03

    Squalene-based adjuvants have been included in influenza vaccines since 1997. Despite several advantages of adjuvanted seasonal and pandemic influenza vaccines, laypeople's perception of such formulations may be hesitant or even negative under certain circumstances. Moreover, in Italian, the term "squalene" has the same root as such common words as "shark" (squalo), "squalid" and "squalidness" that tend to have negative connotations. This study aimed to quantitatively and qualitatively analyze a representative sample of Italian web pages mentioning squalene-based adjuvants used in influenza vaccines. Every effort was made to limit the subjectivity of judgments. Eighty-four unique web pages were assessed. A high prevalence (47.6%) of pages with negative or ambiguous attitudes toward squalene-based adjuvants was established. Compared with web pages reporting balanced information on squalene-based adjuvants, those categorized as negative/ambiguous had significantly lower odds of belonging to a professional institution [adjusted odds ratio (aOR) = 0.12, p = .004], and significantly higher odds of containing pictures (aOR = 1.91, p = .034) and being more readable (aOR = 1.34, p = .006). Some differences in wording between positive/neutral and negative/ambiguous web pages were also observed. The most common scientifically unsound claims concerned safety issues and, in particular, claims linking squalene-based adjuvants to the Gulf War Syndrome and autoimmune disorders. Italian users searching the web for information on vaccine adjuvants have a high likelihood of finding unbalanced and misleading material. Information provided by institutional websites should be not only evidence-based but also carefully targeted towards laypeople. Conversely, authors writing for non-institutional websites should avoid sensationalism and provide their readers with more balanced information.

    Full Text Available This review presents a synthesis and a critique of the development of the existing workfamily (WF literature during the last decade in order to highlight gaps and limitations in current research. The study revises 83 peer-reviewed articles, book chapters and conference presentations (2004-2014 related to WF in economics, management and psychology disciplines, and classifies the current research into three broad themes for future research paths: i definitions and theories; ii background and outcomes of wf conflict, balance and enrichment; and iii methodological gaps. Advances have been made this decade on meta-analysis and the understanding of the positive side of WF interface. Future research opportunities in this field will include a deeper understanding of how to effectively cope with WF conflict, how to achieve WF enrichment, the use of different methods (qualitative, longitudinal and experimental studies on samples of new occupations, and how researchers could address methodological problems (causality, endogeneity, simultaneity, effect size, and self-selection bias to better handle the complexity of WF issues.

    The Electric and Magnetic Fields (EMF) Research and Public Information Dissemination (RAPID) Program was authorized by the Energy Policy Act of 1992 as a near-term effort to expand and accelerate the research needed to address the EMF issue. As required by this legislation, the EMF Interagency Committee, the National EMF Advisory Committee (NEMFAC), and the National Academy of Sciences (NAS) are providing valued input and advice for the direction of this program. With this input and advice, the Department of Energy (DOE) and the National Institute of Environmental Health Sciences (NIEHS) have developed and are implementing five-year program plans. Multi-year health effects research projects and related EMF measurement and exposure assessment projects are underway using funds appropriated in fiscal years 1994, 1995, and 1996 together with voluntary non-Federal contributions. The results of these research projects, along with the results of other EMF research, will be used as input to the hazard evaluation effort, which is the focus of the EMF RAPID Program. A coordinated interagency program is underway to communicate needed information on the EMF issue in a clear manner to the public and other decision makers.

  9. The Application of Intensive Longitudinal Methods to Investigate Change: Stimulating the Field of Applied Family Research.

    The use of intensive longitudinal methods (ILM)-rapid in situ assessment at micro timescales-can be overlaid on RCTs and other study designs in applied family research. Particularly, when done as part of a multiple timescale design-in bursts over macro timescales-ILM can advance the study of the mechanisms and effects of family interventions and processes of family change. ILM confers measurement benefits in accurately assessing momentary and variable experiences and captures fine-grained dynamic pictures of time-ordered processes. Thus, ILM allows opportunities to investigate new research questions about intervention effects on within-subject (i.e., within-person, within-family) variability (i.e., dynamic constructs) and about the time-ordered change process that interventions induce in families and family members beginning with the first intervention session. This paper discusses the need and rationale for applying ILM to family intervention evaluation, new research questions that can be addressed with ILM, example research using ILM in the related fields of basic family research and the evaluation of individual-based interventions. Finally, the paper touches on practical challenges and considerations associated with ILM and points readers to resources for the application of ILM.

    Coastal Florida offers a unique setting for the facilitation of learning about a variety of modern sedimentary environments. Despite the conflicting concept of "virtual" and "actual" field trip, and the uncertainties associated with the implementation and effectiveness, virtual trips provide likely the only way to reach a large diversified student population and eliminate travel time and expenses. In addition, with rapidly improving web and visualization technology, field trips can be simulated virtually. It is therefore essential to systematically develop and assess the educational effectiveness of virtual field trips. This project is developing, implementing, and assessing a series of virtual field trips for teaching undergraduate sedimentary geology at a large four-year research university and introductory geology at a large two-year community college. The virtual field trip is based on a four-day actual field trip for a senior level sedimentary geology class. Two versions of the virtual field trip, one for advanced class and one for introductory class, are being produced. The educational outcome of the virtual field trip will be compared to that from actual field trip. This presentation summarizes Year 1 achievements of the three-year project. The filming, editing, and initial production of the virtual field trip have been completed. Formative assessments were conducted by the Coalition for Science Literacy at the University of South Florida. Once tested and refined, the virtual field trips will be disseminated through broadly used web portals and workshops at regional and national meetings.

    We aimed to assess which factors correlate with collaborative behavior and whether such behavior associates with scientific impact (citations and becoming a principal investigator). We used the R index which is defined for each author as log(Np)/log(I1), where I1 is the number of co-authors who appear in at least I1 papers written by that author and Np are his/her total papers. Higher R means lower collaborative behavior, i.e. not working much with others, or not collaborating repeatedly with the same co-authors. Across 249,054 researchers who had published ≥30 papers in 2000-2015 but had not published anything before 2000, R varied across scientific fields. Lower values of R (more collaboration) were seen in physics, medicine, infectious disease and brain sciences and higher values of R were seen for social science, computer science and engineering. Among the 9,314 most productive researchers already reaching Np ≥ 30 and I1 ≥ 4 by the end of 2006, R mostly remained stable for most fields from 2006 to 2015 with small increases seen in physics, chemistry, and medicine. Both US-based authorship and male gender were associated with higher values of R (lower collaboration), although the effect was small. Lower values of R (more collaboration) were associated with higher citation impact (h-index), and the effect was stronger in certain fields (physics, medicine, engineering, health sciences) than in others (brain sciences, computer science, infectious disease, chemistry). Finally, for a subset of 400 U.S. researchers in medicine, infectious disease and brain sciences, higher R (lower collaboration) was associated with a higher chance of being a principal investigator by 2016. Our analysis maps the patterns and evolution of collaborative behavior across scientific disciplines.

    Wide-field imaging of low-frequency radio telescopes are subject to a number of difficult problems. One particularly pernicious problem is the non-coplanar baseline effect. It will lead to distortion of the final image when the phase of w direction called w-term is ignored. The image degradation effects are amplified for telescopes with the wide field of view. This paper summarizes and analyzes several w-term correction methods and their technical principles. Their advantages and disadvantages have been analyzed after comparing their computational cost and computational complexity. We conduct simulations with two of these methods, faceting and w-projection, based on the configuration of the first-phase Square Kilometre Array (SKA) low frequency array. The resulted images are also compared with the two-dimensional Fourier transform method. The results show that image quality and correctness derived from both faceting and w-projection are better than the two-dimensional Fourier transform method in wide-field imaging. The image quality and run time affected by the number of facets and w steps have been evaluated. The results indicate that the number of facets and w steps must be reasonable. Finally, we analyze the effect of data size on the run time of faceting and w-projection. The results show that faceting and w-projection need to be optimized before the massive amounts of data processing. The research of the present paper initiates the analysis of wide-field imaging techniques and their application in the existing and future low-frequency array, and fosters the application and promotion to much broader fields.

    This paper gives an outline of some actions initiated by the French safety authority in the field of research and test reactors. An important action concerns the definition of the authorisation criteria for the implementation of experiments in these reactors. In particular, it is necessary to define clearly in which conditions an experiment may be authorised internally by the operating organisation or needs a formal approval by the safety authority. The practice related to the systematic safety reassessment of old facilities and the regulatory provisions associated with the decommissioning are presented after a discussion on the ageing issues.

As the education part of an NSF-funded CAREER proposal, I have developed a three-week summer research experience for undergraduate students that links their classroom education with field campaigns aiming to make partial differential equations come "alive" in a practical, applied setting focused on hydrogeologic processes. This course has been offered to freshman- to junior-level undergraduate students from Penn State and also the three co-operating Historically Black Universities (HBUs)--Jackson State University, Fort Valley State University, and Elizabeth City State University-since 2009. Broad learning objectives include applying their knowledge of mathematics, science, and engineering to flow and transport processes in the field and communicating science effectively in poster and oral format. In conjunction with ongoing research about solute transport, students collected field data in the Shale Hills Critical Zone Observatory in Central Pennsylvania, including slug and pumping tests, ground-penetrating radar, electrical resistivity imaging, wireline logging, and optical televiewers, among other instruments. Students conducted tracer tests, where conservative solutes are introduced into a local stream and monitored. Students also constructed numerical models using COMSOL Multiphysics, a research-grade code that can be used to model any physical system; with COMSOL, students create models without needing to be trained in computer coding. With guidance, students built basic models of fluid flow and transport to visualize how heterogeneity of hydraulic and transport properties or variations in forcing functions impact their results. The development of numerical models promoted confidence in predicting flow and

    An open-access magnetic resonance imaging (MRI) system is being developed for use in research on orientational/gravitational effects on lung physiology and function. The open-access geometry enables study of human subjects in diverse orientations. This system operates at a magnetic flux density, considerably smaller than the flux densities of typical other MRI systems, that can be generated by resistive electromagnet coils (instead of the more-expensive superconducting coils of the other systems). The human subject inhales air containing He-3 or Xe-129 atoms, the nuclear spins of which have been polarized by use of a laser beam to obtain a magnetic resonance that enables high-resolution gas space imaging at the low applied magnetic field. The system includes a bi-planar, constant-current, four-coil electromagnet assembly and associated electronic circuitry to apply a static magnetic field of 6.5 mT throughout the lung volume; planar coils and associated circuitry to apply a pulsed magnetic-field-gradient for each spatial dimension; a single, detachable radio-frequency coil and associated circuitry for inducing and detecting MRI signals; a table for supporting a horizontal subject; and electromagnetic shielding surrounding the electromagnet coils.

    In the past two years most of the research effort at the Radiochemistry Laboratory and National Research Council Centre for Radiochemistry and Activation Analysis has been devoted to research and development of activation analysis using the TRIGA Mark II LENA reactor of the University of Pavia. Pile neutrons have been used both in steady state and pulse mode, in the determination of oxygen in non ferrous materials. Neutron activation has been applied to the determination of some atmospheric particulate pollutants. Another field, in which activation analysis has been applied, is forensic research. Methods have been developed for the determination of antimony, barium and copper in gunpowder residues. By using inorganic materials such as molybdenum dibromide, zinc ferrocyanide and cadmium metal in granular form it was possible to set up simple chemical procedures in the activation analysis of trace amounts of noble metals in metallic matrices (high purity nickel and copper), geochemical materials (rocks and meteorites) and biological materials (orchard leaves). Neutron activation analysis was also used to investigate on the extraction of the platinum group metals from iodide and thiocyanate solutions at low concentrations

    Global Science experimental Data hub Center (GSDC) at Korea Institute of Science and Technology Information (KISTI) located at Daejeon in South Korea is the unique datacenter in the country which helps with its computing resources fundamental research fields dealing with the large-scale of data. For historical reason, it has run Torque batch system while recently it starts running HTCondor for new systems. Having different kinds of batch systems implies inefficiency in terms of resource management and utilization. We conducted a research on resource management with HTCondor for several user scenarios corresponding to the user environments that currently GSDC supports. A recent research on the resource usage patterns at GSDC is considered in this research to build the possible user scenarios. Checkpointing and Super-Collector model of HTCondor give us more efficient and flexible way to manage resources and Grid Gate provided by HTCondor helps to interface with the Grid environment. In this paper, the overview on the essential features of HTCondor exploited in this work is described and the practical examples for HTCondor cluster configuration in our cases are presented.

    Increasing utilization of radiation and RI (Radioisotope) in nuclear industry including non-power area has achieved sustainable development of radiation industry. Industries are no longer confined by a single technology or abilities but expanded for application gradually. RIBiomics fields are one of the convergence technology that is recognized on a high-tech industry. Unlike the conventional industry, RI-Biomics field needs to various specialists to perform related task. There is no domestic training program to educate the whole process. This study aims to suggest the plan for improvement of practical skills for specialists in RI-Biomics through development of our training program. For this purpose, we have first investigated the opinion about classification scheme from experts and then analyzed the results in order to reflecting our training program. Based on analyzed results, conformity assessment was executed to organize curriculum through status of constructed device and instructor in domestic. Our training program was performed jointly with KAERI (Korea Atomic Energy Research Institute). RI-Biomics center is prepared with facilities of overall experiment to improve quality of education. Due to the fact that specialists have routine task, we organized a five-day short course to reflect temporal difficulties. We performed a trial operation to 6 participants in RI-Biomics field. Through the survey for the specialists who participated in the program, we evaluated the efficiency of our training program. The results showed that participants were satisfied with the organized curriculum and educational materials. Therefore, our program is expected to be utilized as basic research data to develop feasible program for policy development and to improve practical skills in RI-Biomics.

    The lead author, an Environmental Science teacher at Gary Comer High School (GCHS), a public charter on the South Side of Chicago, accompanied two students over the course of two summers to conduct field research in remote mountain ranges of interior Asia. The expeditions were funded by the National Science Foundation and orchestrated collaboratively with PI Putnam with the purposes of bringing along high school students and teachers (1) to introduce students from urban areas to practical Earth Science and (2) to bolster the Environmental Science curriculum at GCHS by providing real world events to relate to classroom learning. During the first field trip, a student from GCHS and the lead author traveled to western Mongolia to participate in collecting samples for cosmogenic-nuclide dating of glacial landforms. The student performed all parts of sample collection and used the data to create a poster analyzing the rate of recession of the Potanin Glacier. She went on to present her findings at the AGU Fall Meeting 2016. At GCHS, she assisted the teacher in lessons about climate change. Next year she will be attending the University of Vermont to pursue a major in a STEM field. The second student traveled to the Tibetan Plateau in China and also participated fully in sampling activities. She plans on presenting her project on creating 3D models of sample boulders at the AGU Meeting in 2017. She will present her findings to the rest of the student body at GCHS, assist with pertinent Environmental Science lessons for Freshmen, and explain her experience at the Gary Comer Middle School. The lead author faced several restrictions in the classroom due to standardized testing requirements, leading to more focus on testing skills rather than investigative learning. Next year the focus will switch from ACT to SAT standards, allowing more freedom to pursue investigative lessons. The success of adding information on the field experience will be assessed at the end of the 2017

  15. Integration of ultra-high field MRI and histology for connectome based research of brain disorders

    Full Text Available Ultra-high field magnetic resonance imaging (MRI became increasingly relevant for in vivo neuroscientific research because of improved spatial resolutions. However, this is still the unchallenged domain of histological studies, which long played an important role in the investigation of neuropsychiatric disorders. While the field of biological psychiatry strongly advanced on macroscopic levels, current developments are rediscovering the richness of immunohistological information when attempting a multi-level systematic approach to brain function and dysfunction. For most studies, histology sections lost information on three-dimensional reconstructions. Translating histological sections to 3D-volumes would thus not only allow for multi-stain and multi-subject alignment in post mortem data, but also provide a crucial step in big data initiatives involving the network analyses currently performed with in vivo MRI. We therefore investigated potential pitfalls during integration of MR and histological information where no additional blockface information is available. We demonstrated that strengths and requirements from both methods seem to be ideally merged at a spatial resolution of 200 μm. However, the success of this approach is heavily dependent on choices of hardware, sequence and reconstruction. We provide a fully automated pipeline that optimizes histological 3D reconstructions, providing a potentially powerful solution not only for primary human post mortem research institutions in neuropsychiatric research, but also to help alleviate the massive workloads in neuroanatomical atlas initiatives. We further demonstrate (for the first time the feasibility and quality of ultra-high spatial resolution (150 µm isotopic imaging of the entire human brain MRI at 7T, offering new opportunities for analyses on MR-derived information.

    Full Text Available This paper investigates the contribution of marketing research to cultural heritage conservation and sustainability, based on the assumption that the comprehension of the meaning of cultural heritage by new and extended audiences is a prerequisite for the future survival of tangible and intangible heritage. After discussing steps and achievements in the scientific debate on museum marketing, current gaps and possible further developments are considered. Since the early 1980s, marketing research has investigated visitors’ profiles, motivations, and behaviors, and has progressively focused on improving the experience of cultural heritage, especially through the use of information and communication technologies (ICTs in museums and heritage sites. A literature review suggests that scant attention has been paid to qualitative research that is aimed at investigating the knowledge and skills of visitors and non-visitors and their understanding of the value of cultural heritage. Moving from these results, and taking into account recent data about the attitudes and opinions of people in Europe on cultural heritage, the field research focuses on the perception and communication of local cultural heritage among young generations. The results of six focus groups conducted in 2016 with undergraduate and postgraduate students (University of Macerata, Italy are analyzed. The research findings reveal a number of difficulties and limitations with regard to communicating and understanding the value of heritage. In order to better investigate these gaps, the outcomes of this preliminary study could be tested and put to cross-analysis using different methods. However, they do provide useful evidence for understanding the link between audience development and cultural heritage sustainability.

    Full Text Available Layered two-dimensional (2D semiconducting transition metal dichalcogenides (TMDs have been widely isolated, synthesized, and characterized recently. Numerous 2D materials are identified as the potential candidates as channel materials for future thin film technology due to their high mobility and the exhibiting bandgaps. While many TMD filed-effect transistors (FETs have been widely demonstrated along with a significant progress to clearly understand the device physics, large contact resistance at metal/semiconductor interface still remain a challenge. From 2D device research point of view, how to minimize the Schottky barrier effects on contacts thus reduce the contact resistance of metals on 2D materials is very critical for the further development of the field. Here, we present a review of contact research on molybdenum disulfide and other TMD FETs from the fundamental understanding of metal-semiconductor interfaces on 2D materials. A clear contact research strategy on 2D semiconducting materials is developed for future high-performance 2D FETs with aggressively scaled dimensions.

    Resort Anapa (Black Sea coast, Russia) holds leading positions in the Russian market of sanatorium-resort and children's recreation. The 50-200 m sandy beaches of Anapa bay-bar are the main value of the resort. Anapa bay-bar is an extensive accumulative sandy body having the length about 47 km. Obvious attributes of the beaches degradation demanding immediate measures on their protection and restoration are observed in last years. The main reason of degradation is beach material deficiency. To organize researches of the sediments of this extensive natural object is a difficult challenge. It is necessary to reduce number of tests to minimum. It is important to record differences of separate bay-bar sites and to receive comparable data for different seasons and years. Our researches showed that the grain-size sediment composition significantly depends of position on local relief. Consequently, researching of the alongshore change of the sediment size is effectual to realize at this morphological elements. Shelly detritus makes to 30% of total amount of beach sediments. It is necessary to consider that quantitative shell distribution along the coast significantly depends on a configuration of the coastline and an underwater relief. Quantity of the shells for cross-shore profile is maximal near coastline. For identification of the sediment sources and researching of their fluxes to use minerals markers (heavy minerals) is optimum. The maximum of heavy minerals concentration is characteristic for fraction 0.1-0.05mm at depth more 5 m. The maintenance of this fraction within other morphological zones isn't enough for the analysis or is excessively changeable. Use of the revealed features allowed to conduct the representative field researches of grain-size and mineral sediment composition for all morphological zones of underwater and coast part of the Anapa bay-bar. This methodic recommendations are workable for researches on others coast accumulative body. The work is

    Science dissemination has unquestioned role on intermediate science and society and it is a wide subject of research in education, considering that the construction of knowledge flows in different spaces, and, consequently, produces and disseminates representations. It presents as a motivator for reflection and as a necessary tool to prevent that knowledge do not become synonymous with domination and power. Thereby, the Astronomy assumes a remarkable role as a trigger of scientific dissemination process, due to its interdisciplinary character. From this viewpoint and the theoretical and methodological framework of the Theory of Social Representations (TRS), grounded by Serge Moscovici, this research, qualitative in nature, seek to answer: What are the social representations about scientific dissemination of Brazilian researchers that act in the field of astronomy? The work was based on Longhini, Gomide and Fernandes (2013) research, which delineate the Brazilian scientific community involved in Astronomy, identifying two groups of researchers with different training paths: one with postgraduate in education and related fields, and other with postgraduate in Physics or Astronomy. Thus, this study had the subquestion: Does the researchers of these groups have different conceptions about the practices of science dissemination? A sample was composed of six subjects, three of each formative course, who participated in semi-structured interviews analyzed following the steps outlined by Spink (2012). The results show that the science dissemination is part of the researches schedule's, with a positive image relative to promote scientific knowledge to population and similar on practical approach between the two groups. Point to two social representations of science dissemination: one for society in general, moved by passion, anchored in values and beliefs, in satisfaction of seeing the results that their actions bring to people's lives; and the other to their pairs

    The paper contains a brief description of selected investigations carried out in the south Baltic coastal zone, with the particular focus on the history and recent activities conducted at the Coastal Research Station in Lubiatowo (CRS Lubiatowo), Poland. These activities comprise field investigations of nearshore hydrodynamic, lithodynamic, and morphodynamic processes. The study area is a sandy multi-bar shore with a mild slope, much exposed to the impact of waves approaching from NW-NE sector. The shore has a dissipative character which means that the wave energy is subject to gradual dissipation in the nearshore zone and only a small part of this energy is reflected by the shore. Due to the big wind fetch in N-NNE direction, the location of CRS Lubiatowo is favourable to registration of the maximum values of parameters of hydrodynamic and morphodynamic processes which occur in the Baltic during extreme storms.

    The flow-guide tank in China advanced research reactor (CARR) acts as a reactor inlet coolant distributor and play an important role in reducing the flow-induced vibration of the internal components of the reactor core. Numerical simulations of the flow field in the flow-guide tank under different conceptual designing configurations are carried out using the PHOENICS3.2. It is seen that the inlet coolant is well distributed circumferentially into the flow-guide tank with the inlet buffer plate and the flow distributor barrel. The maximum cross-flow velocity within the flow-guide tank is reduced significantly, and the reduction of flow-induced vibration of reactor internals is expected

    The Electric and Magnetic Fields (EMF) Research and Public Information Dissemination (RAPID) Program was authorized by the Energy Policy Act of 1992 (enacted October 24, 1992) to determine whether or not exposure to EMF produced by the generation, transmission, and use of electric energy affects human health. Two Federal agencies, the Department of Energy (DOE) and the National Institute of Environmental Health Sciences (NIEHS), have primary responsibility for the program, but other Federal agencies are key participants as well. This program requires that Federal appropriations be matched by contributions from non-Federal sources. The authorized level of funding for the program was $65 million over a 5-year period (fiscal years 1993-1997 inclusive). For EMF RAPID to be a fully funded program, $32.5 million over 5 years will have to be appropriated by Congress and matched by non-Federal contributions.

    Results of radiation field studies in the experimental channels of the training and research reactor of the Technical University of Dresden are presented. The flux densities of thermal, intermediate and fast neutrons were determined by means of activation detectors., Gamma dose rates have been measured by thermoluminescent dosimeters. The measured results show symmetry with respect to the vertical axis of the reactor and allow to draw conclusions with regard to the efficiency of the individual layers of the shield. They are an essential basis of performing irradiation experiments in the experimental channels. The results of measurements were compared with those of shielding and design calculations. Taking into account the measuring errors and the approximations used in the computational models, no unexpected deviations have been observed. Hence, the measured and calculated results can be assessed to be in good agreement. (author)

    2007-01-01

    Full Text Available This work is based on folklore material, which was gathered during ethno linguistic field research of Serbian traditional lexicon and spiritual culture in Medina village in Hungary in 2002. Folklore material is composed of the sayings by the informer Sava Sokic and primarily can be defined as a series of comical narrations. If we look upon these narrations as a genre of oral speech and within context of ethno linguistic interview, we can notice a complex structure of this oral genre. That is, this genre functions as a memorat with typical beginnings and met textual comments. On the other hand, it respects almost all genre norms, which are characteristic for folklore anecdote. Therefore, comic narrations of Save Sokic, and that are valid also for folklore anecdote in general, can be classified as borderline genre - between memorata and fabulata.

    Potential commercial fusion power systems must be acceptable from a safety and environmental standpoint. They must also promise to be competitive with other sources of energy (i.e., fossil, fission, etc.) when considered from the standpoint of the cost of electricity (COE) and the unit direst cost (UDC) in ($/kWe). These costs are affected by a host of factors including recirculating power, plant availability, construction time, capital cost etc., and are, thus, influenced by technological complexity. In a attempt to meet these requirements, the emphasis of fusion research in the United States has been moving toward smaller, lower-cost systems. There is increased interest in higher beta tokamaks and stellarators, and in compact alternate concepts such as the Reversed Field Pinch (RFP) and the Compact Toroids (CTs) which are, in part, the subject of this paper

    To provide insight into the characteristics of chronic disease self-management by mapping publication status and exploring hotspots. Chronic disease is becoming a major public health issue worldwide, highlighting the importance of self-management in this area. Despite the volume and variety of publications, little is known about how 'chronic disease self-management' has developed, since the first publication 40 years ago. Such is the number of publications in the area, that there is a need for a systematic bibliographic examination to enable clinicians and researchers to navigate this literature. A bibliometric analysis of publications was used. Publication status was achieved using BICOMB software, whereas hotspots were identified with Ucinet software. A search of PubMed was conducted for papers published between 1971-2012. By 2011, the number of publications reached 696, a fourfold increase from the previous 10 years, of which 75% came from the USA and UK. There were 1284 journals, which published chronic disease self-management research, involving various disciplines. The research hotspots highlighted various self-management strategies for the following: diabetes; cardiac vascular and pulmonary chronic disease; pain relief for neoplasms; and obesity. Psychological adjustment was a permeating theme in self-management processes as was using internet-based interventions. Self-management in chronic disease publication has been most evident in developed countries. The bibliographic mapping and identification of publication hotspots provides scholars and practitioners with key target journals, as well as a rigorous overview of the field for use in further research, evidence-based practice and health policy development. © 2014 John Wiley & Sons Ltd.

    Vavilova, I. B.

    The data-oriented astronomy has allowed classifying the Astroinformatics as a new academic research field, which covers various multi-disciplinary applications of the e-Astronomy. Among them are the data modeling, data mining, metadata standards development, data access, digital astronomical databases, image archives and visualization, machine learning, statistics and other computational methods and software for work with astronomical survey and catalogues with their teta- topeta-scale astroinformation resource. In this review we describe briefly the astroinformatics applications and software/services performed for different astronomical tasks in frame of the VIrtual Roentgen and Gamma Observatory (VIRGO) and Ukrainian VirtualObservatory (UkrVO). Among them there are projects based on the archival space-born data of X-ray and gamma space observatories and on the Joint Digitized Archive (JDA) database of astroplate network collections. The UkrVO JDA DR1 deals with the star catalogues (FON, Polar zone, open clusters, GRB star fields) as well as the UkrVO JDA DR2 deals with the Solar System bodies (giant and small planets, satellites, astronomical heritage images).

    Regular physical activity (PA) is an important contributor to a healthy lifestyle. Currently, standard sensor-based methods to assess PA in field-based research rely on a single accelerometer mounted near the body's center of mass. This paper introduces a wearable system that estimates energy expenditure (EE) based on seven recognized activity types. The system was developed with data from 32 healthy subjects and consists of a chest mounted heart rate belt and two accelerometers attached to a thigh and dominant upper arm. The system was validated with 12 other subjects under restricted lab conditions and simulated free-living conditions against indirect calorimetry, as well as in subjects' habitual environments for 2 weeks against the doubly labeled water method. Our stepwise validation methodology gradually trades reference information from the lab against realistic data from the field. The average accuracy for EE estimation was 88% for restricted lab conditions, 55% for simulated free-living conditions and 87% and 91% for the estimation of average daily EE over the period of 1 and 2 weeks

    The exhaust thermoelectric generator (TEG) can generate electric power from a car engine's waste heat. It is important to maintain a sufficient temperature difference across the thermoelectric modules. The radiator is connected to the cooling units of the thermoelectric modules and used to take away the heat from the TEG system. This paper focuses on the research for the integration of a TEG radiator and the flow field of the car chassis, aiming to cool the radiator by the high speed flow around the chassis. What is more, the TEG radiator is designed as a spoiler to optimize the flow field around the car chassis and even reduce the aerodynamic drag. Concentrating on the flow pressure of the radiator and the aerodynamic drag force, a sedan model with eight different schemes of radiator configurations are studied by computational fluid dynamics simulation. Finally, the simulation results indicate that a reasonable radiator configuration can not only generate high flow pressure to improve the cooling performance, which provides a better support for the TEG system, but also acts as a spoiler to reduce the aerodynamic drag force.

  14. Research on the influence of driving harmonic on electromagnetic field and temperature field of permanent magnet synchronous motor

    Full Text Available At present, the drivers with different control methods are used in most of permanent magnet synchronous motors (PMSM. A current outputted by a driver contains a large number of harmonics that will cause the PMSM torque ripple, winding heating and rotor temperature rise too large and so on. In this paper, in order to determine the influence of the current harmonics on the motor performance, different harmonic currents were injected into the motor armature. Firstly, in order to study the influence of the current harmonic on the motor magnetic field, a novel decoupling method of the motor magnetic field was proposed. On this basis, the difference of harmonic content in an air gap magnetic field was studied, and the influence of a harmonic current on the air gap flux density was obtained. Secondly, by comparing the fluctuation of the motor torque in the fundamental and different harmonic currents, the influence of harmonic on a motor torque ripple was determined. Then, the influence of different current harmonics on the eddy current loss of the motor was compared and analyzed, and the influence of the drive harmonic on the eddy current loss was obtained. Finally, by using a finite element method (FEM, the motor temperature distribution with different harmonics was obtained.

    Text-mining offers a technique to identify and extract information from a large corpus of textual data. As an example, this study presents the application of text-mining to assess and compare interest in fitness tracking technology across eating disorder and health-related online communities. A list of fitness tracking technology terms was developed, and communities (i.e., 'subreddits') on a large online discussion platform (Reddit) were compared regarding the frequency with which these terms occurred. The corpus used in this study comprised all comments posted between May 2015 and January 2018 (inclusive) on six subreddits-three eating disorder-related, and three relating to either fitness, weight-management, or nutrition. All comments relating to the same 'thread' (i.e., conversation) were concatenated, and formed the cases used in this study (N = 377,276). Within the eating disorder-related subreddits, the findings indicated that a 'pro-eating disorder' subreddit, which is less recovery focused than the other eating disorder subreddits, had the highest frequency of fitness tracker terms. Across all subreddits, the weight-management subreddit had the highest frequency of the fitness tracker terms' occurrence, and MyFitnessPal was the most frequently mentioned fitness tracker. The technique exemplified here can potentially be used to assess group differences to identify at-risk populations, generate and explore clinically relevant research questions in populations who are difficult to recruit, and scope an area for which there is little extant literature. The technique also facilitates methodological triangulation of research findings obtained through more 'traditional' techniques, such as surveys or interviews. © 2018 Wiley Periodicals, Inc.

    The electromagnetic cold crucible (EMCC) technique is an effective method to melt and directionally solidify reactive and high-temperature materials without contamination. The temperature field and fluid flow induced by the electromagnetic field are very important for melting and controlling the microstructure. In this article, a 3D EMCC model for calculating the magnetic field in the charges (TiAl alloys) using the T-Ω finite element method was established and verified. Magnetic fields in the charge under different electrical parameters, positions and dimensions of the charge were calculated and analyzed. The calculated results show that the magnetic field concentrates in the skin layer, and the magnetic flux density ( B) increases with increasing of the frequency, charge diameter and current. The maximum B in the charge is affected by the position of the charge in EMCC ( h 1) and the charge height ( h 2), which emerges at the middle of coils ( h c) when the relationship of h c < h 1 + h 2 < h c + δ is satisfied. Lower frequency and smaller charge diameter can improve the uniformity of the magnetic field in the charge. Consequently, the induced uniform electromagnetic stirring weakens the turbulence and improves temperature uniformity in the vicinity of the solid/liquid (S/L) interface, which is beneficial to forming a planar S/L interface during directional solidification. Based on the above conclusions, the TiAlNb alloy was successfully melted with lower power consumption and directionally solidified by the square EMCC.

    2009-01-01

    The NASA Glenn Research Center (GRC) designed, developed, and installed, a 37.5 kW DC photovoltaic (PV) Solar Field in the GRC West Area in the 1970s for the purpose of testing PV panels for various space and terrestrial applications. The PV panels are arranged to provide a nominal 120 VDC. The GRC Solar Field has been extremely successful in meeting its mission. The PV panels and the supporting electrical systems are all near their end of life. GRC has designed a 72 kW DC grid-tied PV power system to replace the existing GRC West Area Solar Field. The 72 kW DC grid-tied PV power system will provide DC solar power for GRC PV testing applications, and provide AC facility power for all times that research power is not required. A grid-tied system is connected directly to the utility distribution grid. Facility power can be obtained from the utility system as normal. The PV system is synchronized with the utility system to provide power for the facility, and excess power is provided to the utility for use by all. The project transfers space technology to terrestrial use via nontraditional partners. GRC personnel glean valuable experience with PV power systems that are directly applicable to various space power systems, and provide valuable space program test data. PV power systems help to reduce harmful emissions and reduce the Nation s dependence on fossil fuels. Power generated by the PV system reduces the GRC utility demand, and the surplus power aids the community. Present global energy concerns reinforce the need for the development of alternative energy systems. Modern PV panels are readily available, reliable, efficient, and economical with a life expectancy of at least 25 years. Modern electronics has been the enabling technology behind grid-tied power systems, making them safe, reliable, efficient, and economical with a life expectancy of at least 25 years. The report concludes that the GRC West Area grid-tied PV power system design is viable for a reliable

    The focus of this laboratory study was to investigate the chemical and optical properties, and the detection efficiencies, of tar balls generated in the laboratory using the same instruments deployed on the U.S. Department of Energy (DOE) Atmospheric Radiation Measurement (ARM) Climate Research Facility Gulfstream-1 (G-1) aircraft during the 2013 Biomass Burning Observation Project (BBOP) field study, during which tar balls were observed in wildland biomass burning particulate emissions. Key goals of this laboratory study were: (a) measuring the chemical composition of tar balls to provide insights into the atmospheric processes that form (evaporation/oxidation) and modify them in biomass burning plumes, (b) identifying whether tar balls contain refractory black carbon, (c) determining the collection efficiencies of tar balls impacting on the 600oC heated tungsten vaporizer in the Aerodyne Soot Particle Aerosol Mass Spectrometer (SP-AMS) (i.e., given the observed low volatilities, AMS measurements might underestimate organic biomass burning plume loadings), and (d) measuring the wavelength-dependent, mass-specific absorption cross-sections of brown carbon components of tar balls. This project was funded primarily by the DOE Atmospheric System Research (ASR) program, and the ARM Facility made their single-particle soot photometer (SP2) available for September 1-September 31, 2016 in the Aerodyne laboratories. The ARM mentor (Dr. Sedlacek) requested no funds for mentorship or data reduction. All ARM SP2 data collected as part of this project are archived in the ARM Data Archive in accordance with established protocols. The main objectives of the ARM Biomass Burning Observation Period (BBOP, July-October, 2013) field campaign were to (1) assess the impact of wildland fires in the Pacific Northwest on climate, through near-field and regional intensive measurement campaigns, and (2) investigate agricultural burns to determine how those biomass burn plumes differ from

    2015-04-01

    The air-snow-sea ice system plays an important role in the global cycling of nitrogen, halogens, trace metals or carbon, including greenhouse gases (e.g. CO2 air-sea flux), and therefore influences also climate. Its impact on atmospheric composition is illustrated for example by dramatic ozone and mercury depletion events which occur within or close to the sea ice zone (SIZ) mostly during polar spring and are catalysed by halogens released from SIZ ice, snow or aerosol. Recent field campaigns in the high Arctic (e.g. BROMEX, OASIS) and Antarctic (Weddell sea cruises) highlight the importance of snow on sea ice as a chemical reservoir and reactor, even during polar night. However, many processes, participating chemical species and their interactions are still poorly understood and/or lack any representation in current models. Furthermore, recent lab studies provide a lot of detail on the chemical environment and processes but need to be integrated much better to improve our understanding of a rapidly changing natural environment. During a 3-day workshop held in Cambridge/UK in October 2013 more than 60 scientists from 15 countries who work on the physics, chemistry or biology of the atmosphere-snow-sea ice system discussed research status and challenges, which need to be addressed in the near future. In this presentation I will give a summary of the main research questions identified during this workshop as well as ways forward to answer them through a community-based interdisciplinary approach.

    Full Text Available In this article, the fundamentals of the training process of researchers on the Master in Pedagogy of the Mother Tongue context are explained. The reflection is oriented from projects that are developed in the first writing cycle. It presents the accompaniment process in the disciplinary, pedagogical, didactic and investigative field, starting from the teaching of writing problem in the first education. It starts from recognizing prescriptive and normative practices of language teaching in which writing is unknown as a social activity and the evolutionary process is not taken into account, nor a scaffolding that enhances what children already know favors their appropriation from social interaction and the granting of differentiated aid. In the same way, the article shows how, from the action research, transformative didactic proposals are being constructed, within the pedagogy by projects framework. That seek to correspond with the fundamentals of an interaction and sociocultural theory of learning and with a socio-discursive perspective of the acquisition of writing in which it is recognized as a fundamentally social, intentional, situated activity and its learning is constructed in interaction processes.

    With rising interest of nano technology R and D, nano risk researches have been greatly studied recently. They attract much attention since influence of nano products in the society is not well-known. Now the current state of nano risk research field is not fully investigated, and the object is overviewing this structure until 2008 and predicting the direction of next-coming studies. Nano risk 1611 papers were searched out with certain query and further refinement. And these papers were clustered by bibliometric method. The selected papers were clustered to seven parts and visually seen as aggregated blocks. Each cluster was labeled with proper name by analyzing in detail and the content of each cluster was classified with three terms, i.e. 'Material', 'Hazard' and 'Kinetics'. The biggest cluster was cluster no. 0 'atmospheric nanoparticles', and secondly cluster no. 1 'nanoparticles used in imaging', thirdly cluster no. 2 'toxicity of manufactured nano materials'. Furthermore, historical trend of the number of papers of each cluster was studied year by year. From the all results, short-term future predicting was performed by examining titles of papers or transition of the number of papers in each cluster and by watching the cluster position and gaps between clusters.

    This study presents a implementation purpose of a protection system for research nuclear reactors by using a programed device FPGA (Field Programmable Gate Array). As well as logic protection method involved on an automatic shutdown (TRIP) of a reactor, that ensure the security on such systems. These new control and operation mechanics are developed to guarantee that the security limits of a power plant are not exceeded, these mechanics can work isolated or in groups to safe guard the security levels. For this implementation to be completed, there will be presented the main aspects and concepts referred to protection systems, mostly about research nuclear reactors, with some applications terms exposed. The system proposed at this paper was developed following the VHDL (Very High Speed Integrated Circuits) hardware describing language, and the Modelsim software from Altera Software to program the automatic turning off routines, and hypothetical simulations for such. The results show that for every software application for supporting nuclear reactors, like security devices, they have to meet the IEC 60880 criteria. This paper have great importance, seeing that nuclear reactor security systems, are a basic element for ensure the reactor security. (author)

    Full Text Available With recent advances in biotechnology, the resurrection of recently extinct species has become a possibility, provoking a debate about the wisdom of what has become known as de-extinction. Regardless of the current feasibility and ethical controversies over de-extinction, ongoing technological advancement is likely to result in resurrected species in the near future. In our opinion, de-extinction will be followed by proposals for reintroduction into the wild. We argue that this development could be valuable for the advancement of ecological understanding and conservation.  However, the current conversations are happening in a vacuum. We therefore call for the initiation of field experiments using physiological and ecological surrogates. This type of research could shed light on the potential impacts of resurrected animals on modern ecosystems. While this research would have challenges, it could provide valuable information on th ecology of the past and better prepare scientists and wildlife managers for de-extinction.

    DOE-EM, Office of Groundwater and Soil Remediation and DOE Richland, in collaboration with the Hanford site and Pacific Northwest National Laboratory, have established the Deep Vadose Zone Applied Field Research Center (DVZ-AFRC). The DVZ-AFRC leverages DOE investments in basic science from the Office of Science, applied research from DOE EM Office of Technology Innovation and Development, and site operation (e.g., site contractors [CH2M HILL Plateau Remediation Contractor and Washington River Protection Solutions], DOE-EM RL and ORP) in a collaborative effort to address the complex region of the deep vadose zone. Although the aim, goal, motivation, and contractual obligation of each organization is different, the integration of these activities into the framework of the DVZ-AFRC brings the resources and creativity of many to provide sites with viable alternative remedial strategies to current baseline approaches for persistent contaminants and deep vadose zone contamination. This cooperative strategy removes stove pipes, prevents duplication of efforts, maximizes resources, and facilitates development of the scientific foundation needed to make sound and defensible remedial decisions that will successfully meet the target cleanup goals for one of DOE EM's most intractable problems, in a manner that is acceptable by regulators.

    The development of the low voltage neutron generators (NGS) has contributed considerably to the scope of nuclear research and the economical application of nuclear methods. Such simple instruments are used to produce 14 MeV and 3 MeV neutrons via the 3{sup H}(d,n)4{sup H}e and 2{sup H}(d,n)3{sup H}e reactions,respectively. The neutrons are very widely used and are inexpensive, easy to install and operate, therefore, in addition to nuclear physicists, there are a number of groups of scientists who use low voltage accelerators as tools for pure and applied research, service and education. The aim of this work is to review shortly those problems and methods of science and technology where the neutrons produced in the D-T and D-D reactions play the main role. A wide range of experiments with the detection of neutrons and charged particles is available including the study of shielding and the generator technology itself. N.G. are recently widely used for the determination of neutron data needed for fast reactor and thermonuclear devices. The principles and techniques of the possible uses of neutron generators in technology and research are summarized. The review is devoted to:- Give a short review of the most important operational characteristics of the neutron generators and the necessary instruments needed for application. Outline the main applications of the neutron generators in neutron activation and prompt radiation analysis in various fields(metallurgy, chemistry, biology, meteoritic and lunar studies, geology and mining, etc...) fast neutron therapy, and radiation effects. 2 figs.

  15. Socialization into science: An ethnographic study in a field research station

    Science.gov (United States)

    Calovini, Theresa Ann

    While the place of language in building the tasks and activities of the science classroom has received attention in the education literature, how students do the work of affiliation building through language remains poorly understood. This dissertation is based on ethnographic research in an apprenticeship learning situation at a biological field research station. I carried out this research with five undergraduates apprentices. I focus on how the language used in this apprenticeship situation positioned the apprentices with science. Issues of access and diversity in science education have motivated this research but this point can be missed because the five apprentices were all fairly successful in university science. They had all secured their job for the summer as paid research assistants. Yet, even with these successful students, science had a complicated place in their lives. I draw on Gee's (1999) notion of Discourse to understand this complexity. I focus on four Discourses--- Science, Knowing about the Animals, Senior Projects and RAships, and Relationships ---which were important in the apprentices' learning about and socialization with science. I try to understand the inter-workings of these four Discourses through a detailed analysis of three conversations involving one of the participants, Michelle. Michelle's use of narrative emerged as a linguistic resource which she used to explore dilemmas she experienced in the tensions between these four Discourses. Michelle was in many ways an ideal apprentice. She did her job well and she sought and received expert advice on her Senior project. Nonetheless, Michelle faced obstacles in her pursuit of a career in science and these obstacles related to language use and her use of narrative. I show how her use of narrative either facilitated or impeded her learning, depending on the context of the interaction. My analysis of Discourse points to important issues in language use by both students and teachers, with

  17. Astrobiology Results from ILEWG EuroMoonMars Analogue Field Research

    Science.gov (United States)

    Foing, Bernard H.

    We give an update on the astrobiology results from a series of field research campaigns (ILEWG EuroMoonMars) in the extreme environment of the Utah desert. These are relevant to prepare future lunar landers and polar sample return missions, interpret Moon-Mars data (eg SMART1, LRO, Mars Express, MRO, MER, MSL), study habitability and astrobiology in Moon-Mars environments, or to test human-robotic surface EVA or base operations. In the frame of ILEWG EuroMoonMars campaigns (2009 to 2013) we deployed at Mars Desert Research station near Hanksville Utah, a suite of instruments and techniques [0, 1, 2, 9-11] including sample collection, context imaging from re-mote to local and microscale, drilling, spectrometers and life sensors. We analyzed how geological and geo-chemical evolution affected local parameters (mineralogy, organics content, environment variations) and the habitability and signature of organics and biota. Results: Among the important findings are the diversity in the composition of soil samples even when collected in close proximity, the low abundances of detectable PAHs and amino acids and the presence of biota of all three domains of life with significant heterogeneity. An extraordinary variety of putative extremophiles was observed [3,4,9]. A dominant factor seems to be soil porosity and lower clay-sized particle content [6-8]. A protocol was developed for sterile sampling, contamination issues, and the diagnostics of biodiversity via PCR and DGGE analysis in soils and rocks samples [10, 11]. We compare the 2009 campaign results [0-9] to new measurements from 2010-2013 campaigns relevant to: comparison between remote sensing and in-situ measurements; the study of minerals; the detection of organics and signs of life.

    In this short communication, we provide an overview of a relatively newly provided source of altmetrics data which could possibly be used for societal impact measurements in scientometrics. Recently, Altmetric-a start-up providing publication level metrics-started to make data for publications available which have been mentioned in policy-related documents. Using data from Altmetric, we study how many papers indexed in the Web of Science (WoS) are mentioned in policy-related documents. We find that less than 0.5% of the papers published in different subject categories are mentioned at least once in policy-related documents. Based on our results, we recommend that the analysis of (WoS) publications with at least one policy-related mention is repeated regularly (annually) in order to check the usefulness of the data. Mentions in policy-related documents should not be used for impact measurement until new policy-related sites are tracked.

    Bioremediation of metals and radionuclides has had manyfield tests, demonstrations, and full-scale implementations in recentyears. Field research in this area has occurred for many different metalsand radionuclides using a wide array of strategies. These strategies canbe generally characterized in six major categories: biotransformation,bioaccumulation/bisorption, biodegradation of chelators, volatilization,treatment trains, and natural attenuation. For all field applicationsthere are a number of critical biogeochemical issues that most beaddressed for the successful field application. Monitoring andcharacterization parameters that are enabling to bioremediation of metalsand radionuclides are presented here. For each of the strategies a casestudy is presented to demonstrate a field application that uses thisstrategy.

    Full Text Available In market working conditions, the enterprises need to maintain the competitiveness constantly. It is reached due to increase of standards of customer service and application of the latest technologies of management and production, including logistics. Over time there were following kinds of logistics: transport, warehouse, supply, production, etc. Thus, there is some parallel methodological development in the field of logistics and creation of logistic chains and systems at various stages of life cycle of goods. Thus, for city transportations, except high requirements to ecology and the impacts on the person inherent quick search of administrative decisions on effective customer service for the minimum time is. The warehouse logistics is an intermediate link between economic models by definition of stocks and parties of purchase, and transport operations which these indicators influence. Thus, system researches in the field of warehouse and transport logistic allow to coordinate transport and warehouse operations in uniform indicators, and also to expand methods of transport logistics. Planning and management of transport operations with the solution of problems of the target conflict can be used only for continuous transport sizes. First of all it is connected with impossibility of accumulation of transport works. It is necessary to notice feature of the solution of problems of the target conflict which can carry as the end result, and it can be presented by function, including function of distribution of a random variable. Therefore, the solution of a task can be used in imitating modeling. For transport operations it is necessary to consider two cases: the maximum intensity of service can't be increased and possibility of accumulation of intensity of service at the expense of additional resources

The report of Phase I results and conclusions was issued on October 30, 2009. The findings were reviewed by the project partners and the collective recommendation was to proceed with Phase II. Upon the work-conclusion, the Phase II report was issued on March 5, 2012. The scope of work involved the physical testing of a laboratory scale Recuperative Reformer (RR) to validate predicted performances from the feasibility study in Phase I (26% fuel reduction). Although the testing was a successful validation (21% fuel reduction mode), a technical issue 5 arose, namely a Methane Reforming Rate (MRR) roll off or non-sustaining of the methane reforming rate. GTI’s preliminary conclusions were that mechanism(s) producing the methane reforming rate reduction were not entirely known or understood and the chemical kinetics that triggered the roll off mechanism and/or other mechanisms needed to be further evaluated. GTI developed a plan to uncover the reason(s) for not sustaining a satisfactory Methane Reforming Rate (MRR) of the laboratory scale recuperator reformer (RR). The extended testing program consisted primarily of four tasks based on expected outcomes at that time. The project partners reviewed the proposal and recommended the proposed work extension to proceed and suspension of Phase III pending further review of the results of this work identified as Task 2.5. Additional Temperature Threshold Testing was undertaken by GTI and simultaneously independent analysis was carried out by the University of California Davis. Upon completion of the

    The social network analysis (SNA) is a paradigm for analyzing structural patterns in social re- lations, testing knowledge sharing process and identifying bottlenecks of information flow. The purpose of this study was to determine the status of research in the fleld of violence in Iran using SNA. Research population included all the papers with at least one Iranian affiliation published in violence fleld indexed in SCIE, PubMed and Scopus databases. The co-word maps, co-authorship network and structural holes were drawn using related software. In the next step, the active authors and some measures of our network including degree centrality (DC), closeness, eigenvector, betweeness, density, diameter, compactness and size of the main component were assessed. Likewise, the trend of the published articles was evaluated based on the number of documents and their citations from 1972 to 2014. Five hundred and seventy one records were obtained. The five main clusters and hot spots were mental health, violence, war, psychiatric disorders and suicide. The co-authorship network was complex, tangled and scale free. The top nine authors with cut point role and top ten active authors were identified. The mean (standard deviation) of normalized DC, closeness, eigenvector and betweeness were 0.449 (0.805), 0.609 (0.214), 2.373 (7.353) and 0.338 (1.122), respectively. The density, diameter and mean compactness of our co-authorship network were 0.0494, 3.955 and 0.125, respectively. The main component consisted of 216 nodes that formed 17% of total size of the network. Both the number of the documents and their citations has increased in the field of violence in the recent years. Although the number of the documents has recently increased in the field of violence, the information flow is slow and there are not many relations among the authors in the network. However, the active authors have ability to influence the flow of knowledge within the network.

  7. Environmental Assessment for Selection and Operation of the Proposed Field Research Centers for the Natural and Accelerated Bioremediation Research (NABIR) Program

    International Nuclear Information System (INIS)

    2000-01-01

    The US Department of Energy (DOE) Office of Biological and Environmental Research (OBER), within the Office of Science (SC), proposes to add a Field Research Center (FRC) component to the existing Natural and Accelerated Bioremediation Research (NABIR) Program. The NABIR Program is a ten-year fundamental research program designed to increase the understanding of fundamental biogeochemical processes that would allow the use of bioremediation approaches for cleaning up DOE's contaminated legacy waste sites. An FRC would be integrated with the existing and future laboratory and field research and would provide a means of examining the fundamental biogeochemical processes that influence bioremediation under controlled small-scale field conditions. The NABIR Program would continue to perform fundamental research that might lead to promising bioremediation technologies that could be demonstrated by other means in the future. For over 50 years, DOE and its predecessor agencies have been responsible for the research, design, and production of nuclear weapons, as well as other energy-related research and development efforts. DOE's weapons production and research activities generated hazardous, mixed, and radioactive waste products. Past disposal practices have led to the contamination of soils, sediments, and groundwater with complex and exotic mixtures of compounds. This contamination and its associated costs and risks represents a major concern to DOE and the public. The high costs, long duration, and technical challenges associated with remediating the subsurface contamination at DOE sites present a significant need for fundamental research in the biological, chemical, and physical sciences that will contribute to new and cost-effective solutions. One possible low-cost approach for remediating the subsurface contamination of DOE sites is through the use of a technology known as bioremediation. Bioremediation has been defined as the use of microorganisms to biodegrade or

    Full Text Available Nowadays, society’s concern regarding one particular criminal phenomenon committed by minors is growing. This phenomenon is known under a variety of labels very different from each other such as “parents abuse syndrome”, “tyrannical children”, “little dictators”, “ascendant violence”, “inverted violence”, or “child-to-parent violence”. Indeed, this phenomenon is a type of domestic violence constituted by those psychological, physical and/or economical aggressions, and exercised intentionally and repeatedly by under age children towards their parents or towards those other adults who occupy their place. With the present paper, we pretend to contribute to research on this phenomenon from a legal perspective. In order to accomplish this, we perform an approximation to the concept of child-to-parent violence, affirming that it has been the great forgotten in the research about domestic violence developed in our country. On the other hand, we analyze its incidence, which has allowed us to check the increase that is experimenting this problematic in Spain. Furthermore, we observe that the internment is one of the measures enforced with more frequency in these cases, which is why that we approached its study. Taking into consideration that one of the behaviors carried out by minors who assault their parents is the economic abuse and how, many times, they suffer from some type of addiction (to toxic substances, to new technologies, to shopping…, we propose the convenience of modifying the “benefit of release” that they perceive at the end of the measure of internment and we offer some alternatives to its current regulation.

  11. The effects of conducting authentic field-geology research on high school students' understanding of the nature of science, and their views of themselves as research scientists

    Science.gov (United States)

    Millette, Patricia M.

    Authentic field geology research is a inquiry method that encourages students to interact more with their local environment, and by solving genuine puzzles, begin to increase their intuitive understanding of the nature and processes of science. The goal of the current study was to determine if conducting authentic field research and giving high school students the opportunity to present findings to adult audiences outside of the school setting 1) enhances students' understanding of the nature of science, and 2) affects students views of themselves as researchers. To accomplish this, ninth-grade students from a public school in northern New England engaged in a community-initiated glacial geology problem, completed a field research investigation, and presented their findings at several professional conferences. Following the completion of this student-centered field research, I investigated its effects by using a mixed methods approach consisting of qualitative and quantitative data from two sources. These included selected questions from an open-response survey (VNOS-c), and interviews that were conducted with fifteen of the students of different ages and genders. Findings show that conducting original field research seems to have a positive influence on these students' understanding of the NOS as well as the processes of science. Many of the students reported feelings of accomplishment, acceptance of responsibility for the investigation, a sense of their authentic contribution to the body of scientific knowledge in the world, and becoming scientists. This type of authentic field investigation is significant because recent reforms in earth-science education stress the importance of students learning about the nature and processes of scientific knowledge along with science content.

    This study aimed to evaluate the quantity and quality of articles from different countries involving arthroscopy to investigate the characteristics of worldwide research productivity. Web of Science was searched for arthroscopy articles published between 1999 and 2013. The numbers of articles and citations were analyzed to assess the contributions of different countries. Publication activity was adjusted by country population and gross domestic product (GDP). A total of 12,553 articles were published worldwide. The time trend for the number of articles showed an increase of 2.27-fold between 1999 and 2013. North America, Western Europe, and Eastern Asia were the most productive areas. High-income countries published 90.86% of the articles; middle-income countries, 9.11%; and lower-income countries, only 0.02%. The United States published the most articles (35.40%), followed by Germany (9.53%), the United Kingdom (6.80%), the Republic of Korea (5.45%), and Japan (4.76%), and had the highest total citations (78,161). However, Sweden had the highest mean citations (35.56), followed by Switzerland (23.39) and the Netherlands (18.90). There were positive correlations between the number of publications and population/GDP (P arthroscopy increased significantly from 1999 to 2013, with a more than 2-fold increase in volume. The United States was the most productive country as measured by total publications, but when adjusted for population, Switzerland published the highest number of articles, followed by Finland and Sweden. When publications were adjusted for GDP, the Republic of Korea ranked first, with Finland second and Turkey third. Bibliometric analysis allows us to understand contributions of different world regions in scientific research in the field of arthroscopy and gives insight into the quantity and quality of articles related to arthroscopy.

    2017-06-01

    The purpose of this study was to summarize the latest advances and successes in the field of ovarian tissue cryopreservation while identifying gaps in current knowledge that suggest opportunities for future research. A systematic review was performed according to PRISMA guidelines for all relevant full-text articles in PubMed published in English that reviewed or studied historical or current advancements in ovarian tissue cryopreservation and auto-transplantation techniques. Ovarian tissue auto-transplantation in post-pubertal women is capable of restoring fertility with over 80 live births currently reported with a corresponding pregnancy rate of 23 to 37%. The recently reported successes of live births from transplants, both in orthotopic and heterotopic locations, as well as the emerging methods of in vitro maturation (IVM), in vitro culture of primordial follicles, and possibility of in vitro activation (IVA) suggest new fertility options for many women and girls. Vitrification, as an ovarian tissue cryopreservation technique, has also demonstrated successful live births and may be a more cost-effective method to freezing with less tissue injury. Further, transplantation via the artificial ovary with an extracellular tissue matrix (ECTM) scaffolding as well as the effects of sphingosine-1-phosphate (SIP) and fibrin modified with heparin-binding peptide (HBP), heparin, and a vascular endothelial growth factor (VEGF) have demonstrated important advancements in fertility preservation. As a fertility preservation method, ovarian tissue cryopreservation and auto-transplantation are currently considered experimental, but future research may pave the way for these modalities to become a standard of care for women facing the prospect of sterility from ovarian damage.

    The nanomedicine field is fast evolving toward complex, “active,” and interactive formulations. Like many emerging technologies, nanomedicine raises questions of how human subjects research (HSR) should be conducted and the adequacy of current oversight, as well as how to integrate concerns over occupational, bystander, and environmental exposures. The history of oversight for HSR investigating emerging technologies is a patchwork quilt without systematic justification of when ordinary oversight for HSR is enough versus when added oversight is warranted. Nanomedicine HSR provides an occasion to think systematically about appropriate oversight, especially early in the evolution of a technology, when hazard and risk information may remain incomplete. This paper presents the consensus recommendations of a multidisciplinary, NIH-funded project group, to ensure a science-based and ethically informed approach to HSR issues in nanomedicine, and integrate HSR analysis with analysis of occupational, bystander, and environmental concerns. We recommend creating two bodies, an interagency Human Subjects Research in Nanomedicine (HSR/N) Working Group and a Secretary’s Advisory Committee on Nanomedicine (SAC/N). HSR/N and SAC/N should perform 3 primary functions: (1) analysis of the attributes and subsets of nanomedicine interventions that raise HSR challenges and current gaps in oversight; (2) providing advice to relevant agencies and institutional bodies on the HSR issues, as well as federal and federal-institutional coordination; and (3) gathering and analyzing information on HSR issues as they emerge in nanomedicine. HSR/N and SAC/N will create a home for HSR analysis and coordination in DHHS (the key agency for relevant HSR oversight), optimize federal and institutional approaches, and allow HSR review to evolve with greater knowledge about nanomedicine interventions and greater clarity about attributes of concern.

    Elliott, D. G.

    1977-01-01

    Measurements of reaction rail currents, reaction rail voltages, and airgap magnetic fields in tests of the Linear Induction Motor Research Vehicle (LIMRV) were compared with theoretical calculations from the mesh/matrix theory. It was found that the rail currents and magnetic fields predicted by the theory are within 20 percent of the measured currents and fields at most motor locations in most of the runs, but differ by as much as a factor of two in some cases. The most consistent difference is a higher experimental than theoretical magnetic field near the entrance of the motor and a lower experimental than theoretical magnetic field near the exit. The observed differences between the theoretical and experimental magnetic fields and currents do not account for the differences of as much as 26 percent between the theoretical and experimental thrusts.

    Bosi, Maria Lúcia Magalhães

    2012-12-01

    This article analyzes some challenges for knowledge output in the human and social sciences in the public health field, under the current academic assessment model in Brazil. The article focuses on the qualitative research approach in human and social sciences, analyzing its status in comparison to the other traditions vying for hegemony in the public health field, conjugating the dialogue with the literature, especially the propositions pertaining to the social fields present in the work of Pierre Bourdieu, with elements concerning the field's dynamics, including some empirical data. Challenges identified in the article include hurdles to interdisciplinary dialogue and equity in the production of knowledge, based on recognition of the founding place of human and social sciences in the public health field. The article discusses strategies to reshape the current correlation of forces among centers of knowledge in public health, especially those capable of impacting the committees and agendas that define the accumulation of symbolic and economic capital in the field.

    This article addresses the role of scientific divulgation in the interaction between science and society, debating the importance of Astronomy as a prime starter of the scientific divulgation. In the light of Moscovici’s Social Representations Theory, the social representations on scientific divulgation of Brazilian researchers that work in the field of Astronomy are studied. Individuals from different educational trajectories ansewered semi-structured interviews, which were analyzed according to Spink. The results indicate two representations: one for the society at large, moved by passion, based on values and beliefs, and on the satisfaction of seeing the results of their actions on people’s life; and another for their peers. In the first representation, gaps that obstruct the science divulgation emerge, such as the lack of training and the difficulty to use a plain language, the bureaucracy required for the projects’ execution and its negative representation in the media. Other inferences are that Astronomy is neither part of a systematic teaching nor a part of the media at large, and it often presents conceptual mistakes. Those representations find an echo in the theoretical framework, showing that, despite their advances, scientific divulgation and Astronomy Education are in a context of social fragility.

    This descriptive field study examines processes used to evaluate simulation for senior-level Bachelor of Science in Nursing (BSN) students in a capstone course, discusses challenges related to simulation evaluation, and reports the relationship between faculty evaluation of student performance and National Council Licensure Examination for Registered Nurses (NCLEX-RN) first-time passing rates. Researchers applied seven terms used to rank BSN student performance (n = 41, female, ages 22-24 years) in a senior-level capstone simulation. Faculty evaluation was correlated with students' NCLEX-RN outcomes. Students evaluated as "lacking confidence" and "flawed" were less likely to pass the NCLEX-RN on the first attempt. Faculty evaluation of capstone simulation performance provided additional evidence of student preparedness for practice in the RN role, as evidenced by the relationship between the faculty assessment and NCLEX-RN success. Simulation has been broadly accepted as a powerful educational tool that may also contribute to verification of student achievement of program outcomes and readiness for the RN role.

  3. Petroleum environmental research forum field study on biofilters for control of volatile hydrocarbons

    A field study on the treatment of volatile petroleum hydrocarbons (PHC) by biofiltration was conducted by the Petroleum Environmental Research Forum (PERF) between 1992 and 1994. Its objective was to assess the technical, regulatory, and economic feasibility of biofiltration for off-gases from petroleum processing and soil remediation equipment. It involved three small-scale biofilters provided by US vendors, treating off-gas from two soil vapor extraction sites and a source of refinery wastewater. Comprehensive monitoring of biofilter operating parameters and performance was conducted. Typically more than 95% of aromatic compounds such as benzene, and odorous reduced sulfur compounds can be removed at residence times of one minute or less, while removal of more than 70% of light aliphatics will require residence times of several minutes, and will thus require correspondingly large filter volumes and higher capital expenditure. The high percentage removal of aromatic hazardous air pollutants (HAP) and odors can generally be accomplished at comparatively short residence times while the need for high-percentage removal, particular of light aliphatics ( 5 ) will generally render biofiltration noncompetitive. Finally, a preliminary economic comparison of biofilters and established control technologies suggested that biofiltration may, for a representative design case involving off-gas from a refinery wastewater treatment operation, offer considerable savings in total cost of air pollution control for petroleum hydrocarbon streams if regulations require the control of aromatic HAP or odors

    Full Text Available The developments in the culture of democracy have led to shaping of activities in politics and political parties from a marketing point of view. Therefore the concept of political marketing has become a new field of study both for academicians and professionals. The aim of this study is to investigate whether demographic and socio-cultural characteristics of voters differed in their perceptions of political trust. The data, which collected through face-to-face surveys conducted with 574 participants, were analyzed statistically using SPSS package program. According to the analysis results, hypotheses which argue that the confidence variable, which is one of the three factors that constitute the trust perceptions of voters, differs according to age groups, education levels, professional groups and political views were accepted. Also hypotheses which argue that ‘doing non-political works’ variable that is another factor, differs according to education levels, income levels, and occupational groups were accepted, while the other hypotheses were rejected. The communication variable did not differ in term of any characteristic of the participants.  Given the limited work on this topic, the findings of the research which were conceptually in accordance with the previous results, show that this study has made considerable contributions to the literature.

    PART I DESCRIBES IMPORTANT CONTRIBUTIONS MADE BY SOME JAPANESE PIONEERS IN THE FIELD OF NEUROTRANSMITTERS: (their achievements in parentheses) J. Takamine (isolation and crystallization of adrenaline); K. Shimidzu (early hint for acetylcholine as a neurotransmitter); F. Kanematsu (donation of the Kanematsu Memorial Institute in Sydney); T. Hayashi (discovery of the excitatory action of glutamate and the inhibitory action of GABA); and I. Sano (discovery of a high concentration of dopamine in striatum, its reduction in a patient with Parkinson's disease and the treatment with DOPA). In Part II, I present some of my reflections on my research on neurotransmitters. The work of my colleagues and myself has made some significant contributions to the establishment of neurotransmitter roles played by GABA and substance P, the first amino acid and the first peptide neurotransmitters, respectively. By the early 1960s, 3 substances, i.e., acetylcholine, noradrenaline, and adrenaline, had been established as neurotransmitters. Now the number of neurotransmitters is believed to be as many as 50 or even more mainly due to the inclusion of several amino acids and a large number of peptide transmitters.

  6. Circular Business Models: Defining a Concept and Framing an Emerging Research Field

    2017-10-01

    Full Text Available To aid companies in transitioning towards a circular economy and adopting strategies such as reuse, repair, and remanufacturing, the concept of circular business models has been developed. Although the concept draws on contributions from various academic disciplines, and despite its increasingly frequent use, few scholars clearly define what a circular business model is. Understanding about what makes a business model circular is diverse, hampering the theoretical development and practical application of circular business models. This study aims to help frame the field of circular business model research, by clarifying the fundamentals of the concept from the perspectives of resource efficiency and business model innovation. Expanding on these findings, a review of how the concept is used in recent academic literature is provided. It shows that a coherent view is lacking on which resource efficiency strategies classify a business model as circular. This study clarifies which resource efficiency strategies can be deemed as relevant key strategies for circular business models, and suggests a new definition of the concept. With the definition grounded in analysis of the fundamentals in terms of resource efficiency and business models, the study contributes to theoretical advancement and effective implementation of circular business models.

  7. On norms and bodies: findings from field research on cosmetic surgery in Rio de Janeiro, Brazil.

    Brazil has the second highest rate of cosmetic surgery worldwide, provided in a large number of public and private clinics and hospitals, especially in the southeast. This qualitative field research in Rio de Janeiro included participant observation and in-depth interviews with 18 women cosmetic surgery patients, 10 key informants (e.g. psychologists and sociologists) and 12 plastic surgeons. Fifteen of the women were either pre- or post-operative; three had not decided whether to have surgery. When asked about their motivations and expectations of the surgery, the majority of the women said they wanted to be "normal". Most of the surgeons said they acted as empathic companions from decision-making through surgery and beyond. Many of the key informants were critical of what was happening to medical ethics in relation to cosmetic surgery. With the growth in a consumer culture, they saw ethics in medicine becoming more bendable and subject to the "law" of the market. The cult of the body has become a mass phenomenon and taken on an important social dimension in a society where norms and images are broadcast widely by the media. The trend towards body-modification by cosmetic surgery at an early age is increasing dramatically. What demands critical thinking and further investigation are the consequences of cosmetic surgery for physical and mental health. Copyright 2010 Reproductive Health Matters.

    Crop improvement programs require large and meticulous selection processes that effectively and accurately collect and analyze data to generate quality plant products as efficiently as possible, develop superior cropping and/or crop improvement methods. Typically, data collection for such testing is performed by field teams using hand-held instruments or manually-controlled devices. Although steps are taken to reduce error, the data collected in such manner can be unreliable due to human error and fatigue, which reduces the ability to make accurate selection decisions. Monsanto engineering teams have developed a high-clearance mobile platform (Rover) as a step towards high throughput and high accuracy phenotyping at an industrial scale. The rovers are equipped with GPS navigation, multiple cameras and sensors and on-board computers to acquire data and compute plant vigor metrics per plot. The supporting IT systems enable automatic path planning, plot identification, image and point cloud data QA/QC and near real-time analysis where results are streamed to enterprise databases for additional statistical analysis and product advancement decisions. Since the rover program was launched in North America in 2013, the number of research plots we can analyze in a growing season has expanded dramatically. This work describes some of the successes and challenges in scaling up of the rover platform for automated phenotyping to enable science at scale.

    We have built a variable temperature scanning probe microscope (SPM) that covers 4.6 K-180 K and up to 7 T whose SPM head fits in a 52 mm bore magnet. It features a temperature-controlled sample stage thermally well isolated from the SPM body in good thermal contact with the liquid helium bath. It has a 7-sample-holder storage carousel at liquid helium temperature for systematic studies using multiple samples and field emission targets intended for spin-polarized spectroscopic-imaging scanning tunneling microscopy (STM) study on samples with various compositions and doping conditions. The system is equipped with a UHV sample preparation chamber and mounted on a two-stage vibration isolation system made of a heavy concrete block and a granite table on pneumatic vibration isolators. A quartz resonator (qPlus)-based non-contact atomic force microscope (AFM) sensor is used for simultaneous STM/AFM operation for research on samples with highly insulating properties such as strongly underdoped cuprates and strongly correlated electron systems.

  10. Research in the field of neutronics and nuclear data for fusion

    2001-01-01

    A reliable and validated nuclear database is required for the design of a fusion reactor. Neutrons produced by the fusion reactions between deuterium and tritium have a very peaked energy spectrum at 14 MeV, requiring a substantial extrapolation with respect to the database made available from fission studies. The correct evaluation of shielding properties, damage, nuclear heating and of tritium breeding performance in the blanket surrounding the reaction chamber is crucial to the correct reactor design. Moreover, the attractiveness of fusion relies in the low activation of the reactor components and in the minimal production of long-term radioactive waste that is pursued with development of low activation materials. Beside the materials development, Europe is carrying out a co-ordinated program for the development of adequate nuclear database and numerical tools, directed to evaluations, processing, application, and benchmarking of cross sections including uncertainty information. Experimental validation of data and of the relative uncertainties is also pursued, both on material samples and on more design-oriented experiments. A general view of the research work in the field of neutronics and nuclear data for fusion will be given in the presentation, with emphasis to the experimental validation activity.(author)

  11. Spatial distribution of an uranium-respiring betaproteobacterium at the Rifle, CO field research site.

    Directory of Open Access Journals (Sweden)

    Nicole M Koribanics

    Full Text Available The Department of Energy's Integrated Field-Scale Subsurface Research Challenge Site (IFRC at Rifle, Colorado was created to address the gaps in knowledge on the mechanisms and rates of U(VI bioreduction in alluvial sediments. Previous studies at the Rifle IFRC have linked microbial processes to uranium immobilization during acetate amendment. Several key bacteria believed to be involved in radionuclide containment have been described; however, most of the evidence implicating uranium reduction with specific microbiota has been indirect. Here, we report on the cultivation of a microorganism from the Rifle IFRC that reduces uranium and appears to utilize it as a terminal electron acceptor for respiration with acetate as electron donor. Furthermore, this bacterium constitutes a significant proportion of the subsurface sediment community prior to biostimulation based on TRFLP profiling of 16S rRNA genes. 16S rRNA gene sequence analysis indicates that the microorganism is a betaproteobacterium with a high similarity to Burkholderia fungorum. This is, to our knowledge, the first report of a betaproteobacterium capable of uranium respiration. Our results indicate that this microorganism occurs commonly in alluvial sediments located between 3-6 m below ground surface at Rifle and may play a role in the initial reduction of uranium at the site.

    The most popular social networking site in the United States is Facebook, an online forum where circles of friends create, share, and interact with each other's content in a nonpublic way. Our objectives were to understand (1) the most commonly used terms and phrases relating to breast cancer screening, (2) the most commonly shared website links that other women interacted with, and (3) the most commonly shared website links, by age groups. We used a novel proprietary tool from Facebook to analyze all of the more than 1.7 million unique interactions (comments on stories, reshares, and emoji reactions) and stories associated with breast cancer screening keywords that were generated by more than 1.1 million unique female Facebook users over the 1 month between November 15 and December 15, 2016. We report frequency distributions of the most popular shared Web content by age group and keywords. On average, each of 59,000 unique stories during the month was reshared 1.5 times, commented on nearly 8 times, and reacted to more than 20 times by other users. Posted stories were most often authored by women aged 45-54 years. Users shared, reshared, commented on, and reacted to website links predominantly to e-commerce sites (12,200/1.7 million, 36% of all the most popular links), celebrity news (n=8800, 26%), and major advocacy organizations (n=4900, 15%; almost all accounted for by the American Cancer Society breast cancer site). On Facebook, women shared and reacted to links to commercial and informative websites regarding breast cancer and screening. This information could inform patient outreach regarding breast cancer screening, indirectly through better understanding of key issues, and directly through understanding avenues for paid messaging to women authoring and reacting to content in this space. ©Marco Huesch, Alison Chetlen, Joel Segel, Susann Schetter.

    The study presents the research output of 40 globally top-ranked authors, publishing in the field of osteoporosis. Their h-index is compared with the Scientific Quality Index (SQI), a novel indicator. Using SQI, 92.5% of the authors changed their initial positions in the general ranking. SQI partially depends on bibliometric measures different from those influencing h-index and may be considered as an assessment tool, reflecting more objective, qualitative, rather than quantitative, features of individual scientific output. The study approaches the research output of 40 globally top-ranked authors in the field of osteoporosis. The assessed authors were identified in the Scopus database, using the key word "osteoporosis" and the h-index data, collected during the last decade (2008-2017). The data, concerning the scientific output, expressed by the h-index, were compared with a novel indicator of scientific quality-called the Scientific Quality Index (SQI). SQI is calculated according to the following formula: Parameter No. 1 + Parameter No. 2, where: Parameter No. 1 (the percent of papers cited ≥ 10 times) the number of papers cited ≥ 10 times (excluding self-citations and citations of all co-authors) is divided by the number of all the published papers (including the papers with no citation) × 100%, Parameter No. 2 (the mean number of citations per paper) the total number of citations (excluding self-citations and citations of all co-authors) divided by the number of all published papers (including papers with no citation). The following research output values were obtained: the citation index, 2483.6 ± 1348.7; the total number of papers, 75.1 ± 23.2; the total number of cited papers, 69.3 ± 22.0; the number of papers cited, at least, 10 times, 45.4 ± 17.2; the percent of papers cited, at least, 10 times, 59.9 ± 10.0; and the mean citations per paper, 32.8 ± 15.0. The mean value of Hirsch index was 24.2 ± 6.2 and SQI

    2007-09-01

    Full Text Available This article aims to introduce an ethnic group inhabiting a common virtual space in the World Wide Web (WWW, while being physically located in different socio-geographical contexts. Potentially global in its geographical extent, this social formation is constituted by means of interrelating virtual-global dimensions with physically grounded parts of the actors' lifeworlds. In addition, the communities' social life relies on specific communicative practices joining mediated forms of communication with co-presence based encounters. Ethnographic research in a pluri-local and computer-mediated field poses a set of problems which demand thorough reflection as well as a search for creative solutions. How can the boundaries of the field be determined? What does "being there" signify in such a case? Is it possible to enter the field while sitting at my own desk, just by visiting the respective site in the WWW, simply observing the communication going on without even being noticed by the subjects in the field? Or does "being in the field" imply that I ought to turn into a member of the studied community? Am I supposed to effectively live with the others for a while? And then, what can "living together" actually mean in that case? Will I learn enough about the field simply by participating in its virtual activities? Or do I have to account for the physically grounded dimensions of the actors' lifeworlds, as well? Ethnographic research in a pluri-local and computer-mediated field in practice raises a lot of questions regarding the ways of entering the field and being in the field. Some of them will be discussed in this paper by means of reflecting research experiences gained in the context of a recently concluded case study. URN: urn:nbn:de:0114-fqs0703321

  18. Higher tier field research in ecological risk assessment: a case study

    Energy Technology Data Exchange (ETDEWEB)

    Faber, J. [Alterra, Wageningen (Netherlands)

    2003-07-01

    A newly developed basic procedure for site-specific ecological risk assessment in The Netherlands was followed in practice for the first time. In line with conventional Triade approaches, the procedure includes multidisciplinary parameters from environmental chemistry, toxicology and ecology to provide multiple weight of evidence. However, land use at the contaminated site and its vicinity is given more importance, and research parameters are selected in accordance to specific objectives for land use in order to test for harmful effects to underlying ecosystem services. Moreover, the approach is characterized by repetitive interactions between stakeholders and researching consultants, in particular with respect to the choice of parameters and criteria to assess the results. The approach was followed in an ecological risk assessment to test the assumptions underlying a soil management plant for a rural area in The Netherlands, called 'Krimpenerwaard'. Throughout this region some 5000 polder ditches have been filled with waste materials originating from local households, waterway sludge, industrial wastes, car shredders, and more. Several sites are severely polluted by heavy metals, cyanide, PAH or chlorinated hydrocarbons and require remediation or clean up. However, the exact distribution of these wastes over the entire region is scarcely known, and the Krimpenerwaard as a whole is treated as one case of serious soil pollution. A soil management plan was constructed by 13 stakeholding parties, aiming for a 'functional clean up' in view of land use, by means of covering 'suspected' categories of wastes with a 30-cm layer of local type soil. The ecological risk assessment aims to verify the assumptions in the soil management plan regarding the prevention of possible undesirable effects induced by the various waste materials. A tiered approach is followed, including a screening for bioavailable contaminants, a testing for general effects

    The scientific focus of this study was to investigate and quantify the mass loadings, chemical compositions, and optical properties of biomass burning particulate emissions generated in the laboratory from Western U.S. fuels using a similar instrument suite to the one deployed on the U.S. Department of Energy (DOE) Atmospheric Radiation Measurement (ARM) Climate Research Facility Gulfstream-1 (G-1) aircraft during the 2013 Biomass Burning Observation Project (BBOP) field study (Kleinman and Sedlacek, 2013). We deployed the single-particle soot photometer (SP2) to make measurements of biomass burning refractory black carbon (rBC) mass loadings and size distributions to correlate with non-refractory particulate matter (NR-PM; i.e., HR-AMS) and rBC (SP-AMS) measurements as a function of photo-oxidation processes in an environmental chamber. With these measurements, we will address the following scientific questions: 1. What are the emission indices (g/kg fuel) of rBC from various wildland fuels from the Pacific Northwest (i.e., relevant to BBOP analysis) as a function of combustion conditions and simulated atmospheric processing in an environmental chamber? 2. What are the optical properties (e.g., mass-specific absorption cross-section [MAC], single-scattering albedo [SSA], and absorption Angstrom exponent [AAE)] of rBC emitted from various wildland fuels and how are they impacted by atmospheric processing? 3. How does the mixing state of rBC in biomass-burning plumes relate to the optical properties? 4. How does the emitted rBC affect radiative forcing?

    Based on the characteristics of the three dimensional partition, the triangulation of discrete date sets is improved by the method of point-by-point insertion. The discrete data for the radiation field by theoretical calculation or actual measurement is restructured, and the continuous distribution of the radiation field data is obtained. Finally, the 3D virtual scene of the nuclear facilities is built with the VR simulation techniques, and the visualization of the 3D radiation field is also achieved by the visualization mapping techniques. It is shown that the method combined VR and Delaunay triangulation could greatly improve the quality and efficiency of 3D radiation field visualization. (authors)

    The amplitude calibration of an electric field sensor is important in the measurement of electromagnetic pulse. In this paper, an arbitrary waveform generator (AWG) is used to generate multi-waveform electric field in the TEM cell and the dipole antenna pulsed electric field sensor is calibrated. In the frequency band of the sensor, the calibrated amplitude coefficients with different waveforms are identical. The coefficient derived from the TEM cell calibration system suits to the measurement of unknown electric field pulse within the frequency band. (authors)

    To analyze the size and location of the calibration field and the stabilization of systematic error parameters, calibration field designing for airborne Position and Orientation System (POS) using actual photogrammetric data is discussed in this paper. The empirical results have verified that a region of 4 strips with 7 images in each strip is appropriate for use as a calibration field, whose location should be within 1° in longitude from the center of the project. If the equipment is changed, the POS must be recalibrated. Otherwise, the flight interval of the calibration field should not exceed 30 days.

    The silicon field-effect transistors were investigated to use in circuits for stabilization of current and voltage. As in gallium arsenide field-effect transistors, in silicon field-effect transistors with p-n-junction a new mechanism of saturation of the drain current is experimentally found out due to both transverse and longitudinal compression of channel by additional resistance between the source and the gate of the transistor. The criteria for evaluating the coefficients of stabilization of transient current suppressors and voltage stabilizator based on the field-effect transistor are considered. (authors)

    The state of art and the progress in application of semantic technologies in the field of scientific and research activity have been analyzed. Even elementary empirical comparison has shown that the semantic search engines are superior in all respects to conventional search technologies. However, semantic information technologies are insufficiently used in the field of scientific and research activity in Russia. In present paper an approach to construction of ontological model of knowledge base is proposed. The ontological model is based on the upper-level ontology and the RDF mechanism for linking several domain ontologies. The ontological model is implemented in the Protégé environment.

    Being a natural environmental factor, an electromagnetic field exists from the beginning of the life on Earth and it has an influence on maintenance of life processes. Natural electromagnetic fields affect day and year rhythms of plants, animals and humans. As a result of an electromagnetic field's activity, there occurs a disorder of blood platelets' function, which may, in consequence, lead to acute and chronic conditions dangerous to health and life. The aim of this work was to assess the influence, which a shape of an electromagnetic field of low frequency has on generating free radicals and enzymatic activity of superoxide dismutase in human blood platelets. Suspension of human blood platelets was subjected to activity of electromagnetic field of different shapes, frequency of 50 Hz and induction of 10 mT for 15 and 30 minutes. An electromagnetic field was generated with Helmholtz coils arranged on a bracket, inside of which test tubes with the blood platelets' suspension were put. Next, they were subjected to an activity of a specific electromagnetic field. The measurement of free radicals generation indicated an increase, in comparison with the initial values, after 15 minutes as well as 30 minutes of exposition, regardless of the electromagnetic field's shape, whereas the enzymatic activity of superoxide dismutase decreased, in comparison with the initial values, after 15 minutes as well as 30 minutes of exposition, regardless of the applied electromagnetic field's shape. Basing on obtained results, it may be stated that the level of generating free radicals as well as the level of enzymatic activity of superoxide dismutase in tested blood cells indicates significant dependence on an electromagnetic field's shape. The greatest changes have been observed during the activity of a rectangular and triangular pulse.

    This report summarises 10 years of research on power frequency electric and magnetic fields. Cancer is the topic for which most research has been carried out during the 10-year-period. Epidemiological studies have shown statistical correlations between long time exposure to magnetic fields and a few forms of cancer. The most obvious correlation is between childhood leukaemia and magnetic fields from power lines. However, the correlations correspond to very small increases in risk and since there is no experimental evidence and no trustworthy mechanism exists, a cause-and-effect relationship cannot be established. Furthermore, there are also comprehensive and well-performed studies which show no correlations. Some studies indicate a correlation between electric and magnetic fields and cognitive functions and diffuse central nervous symptoms. The results show correspondence with the hypothesis that magnetic fields cause a chronic stress effect to the central nervous system. A relatively strong correlation has been shown between ALS (amyotrophic lateral sclerosis) and electricity related labour. EMF is however only one of several conceivable explanations. An equivalent, although weaker, correlation has also been shown for Alzheimer's decease. It can be stated that frequent electric and magnetic fields do not seem to have any influence on reproducibility, such as damage on the foetus or negative effects on the reproduction in humans or animals. A potentially important area is the effect on the immune system in humans and animals. In fact, it has been noted that magnetic fields may activate the immune system whilst long term exposure seems to impoverish the capacity of the immune system. The research on field variables and connected mechanisms shows that intermittent magnetic fields have stronger biological impact than continuous fields. Another observation is that biological effects often appear as window effects in amplitude, frequency and sometimes even in time

    One of the major problems encountered in the development of Tokamak type fusion reactors is the presence of impurities in the plasma. The PDX device is designed to study the operation of poloidal magnetic field divertors and consequent magnetic limiters for controlling and reducing the amount of impurities. A system of coils placed at specific locations produces a required field configuration for the poloidal divertor. This paper describes the system of energy supplies required and the interrelations of field coil currents during plasma current initiation, growth and steady state

    This article addresses methodological issues emerging from research conducted with Trans in the Center, an LGBT activist group in Tel Aviv, Israel. It addresses some complex issues related to the politics and ethics of applying queer and feminist methodology to qualitative research in a trans, queer, and feminist community space. The focus is on two issues: the researcher's positionality vis-à-vis the participants and selecting the appropriate methodology in relation to the characteristics of the group under study. Such issues demonstrate how queer and feminist principles are articulated and interwoven in geographical-spatial research in two different dimensions: in the research practice and methodology and in the practices and the spaces created by the activity of the researched group itself. I conclude with insights arising from the attempt to apply feminist and queer paradigms in both theory and research, and I call for their integration into geographical research.

    The present contract supported work by Daniel H. Frieden, Emil J, Martinec and Stephen H. Shenker (principal investigators), Research Associates, and graduate students in theoretical physics at the University of Chicago. Research has been conducted in areas of string theory and two dimensional conformal and superconformal field theory. The ultimate objectives have been: to expose the fundamental structure of string theory so as to eventually make possible effective nonperturbative calculations and thus a comparison of sting theory with experiment, the complete classification of all two dimensional conformal and superconformal field theories thus giving a complete description of all classical ground states of string and of all possible two (and 1 + 1) dimensional critical phenomena, and the development of methods to describe, construct and solve two dimensional field theories. Work has also been done on skyrmion and strong interaction physics
