The research aimed to enhance Grade 10 Thai students' scientific argumentation in learning about electric field through science, technology, and society (STS) approach. The participants included 45 Grade 10 students who were studying in a school in Nongsonghong, Khon Kaen, Thailand. Methodology regarded interpretive paradigm. The intervention was the force unit which was provided based on Yuenyong (2006) STS approach. Students learned about the STS electric field unit for 4 weeks. The students' scientific argumentation was interpreted based on Toulmin's argument pattern or TAP. The TAP provided six components of argumentation including data, claim, warrants, qualifiers, rebuttals and backing. Tools of interpretation included students' activity sheets, conversation, journal writing, classroom observation and interview. The findings revealed that students held the different pattern of argumentation. Then, they change pattern of argumentation close to the TAP. It indicates that the intervention of STS electric field unit enhance students to develop scientific argumentation. This finding may has implication of further enhancing scientific argumentation in Thailand.

Field Science--the Nature and Utility of Scientific Fields.
Casadevall, Arturo; Fang, Ferric C
2015-09-08
Fields are the fundamental sociological units of science. Despite their importance, relatively little has been written about their emergence, composition, structure, and function in the scientific enterprise. This essay considers the nature of fields and their important role in maintaining information and providing normative standards for scientific work. We suggest that fields arise naturally as a consequence of increasing information and scientific specialization. New fields tend to emerge as research communities grow, which may reflect biologically determined optima for the size of human groups. The benefits of fields include the organization of scientists with similar interests into communities that collectively define the next important problems to pursue. In the discipline of microbiology, fields are often organized on the basis of phylogenetic differences between microorganisms being studied. Although fields are essential to the proper functioning of science, their emergence can restrict access by outsiders and sustain dogmas that hinder progress. We suggest mechanisms to improve the functioning of scientific fields and to promote interdisciplinary interaction between fields. Copyright © 2015 Casadevall and Fang.

Public perception and communication of scientific uncertainty.
Broomell, Stephen B; Kane, Patrick Bodilly
2017-02-01
Understanding how the public perceives uncertainty in scientific research is fundamental for effective communication about research and its inevitable uncertainty. Previous work found that scientific evidence differentially influenced beliefs from individuals with different political ideologies. Evidence that threatens an individual's political ideology is perceived as more uncertain than nonthreatening evidence. The authors present 3 studies examining perceptions of scientific uncertainty more broadly by including sciences that are not politically polarizing. Study 1 develops scales measuring perceptions of scientific uncertainty. It finds (a) 3 perceptual dimensions of scientific uncertainty, with the primary dimension representing a perception of precision; (b) the precision dimension of uncertainty is strongly associated with the perceived value of a research field; and (c) differences in perceived uncertainty across political affiliations. Study 2 manipulated these dimensions, finding that Republicans were more sensitive than Democrats to descriptions of uncertainty associated with a research field (e.g., psychology). Study 3 found that these views of a research field did not extend to the evaluation of individual results produced by the field. Together, these studies show that perceptions of scientific uncertainty associated with entire research fields are valid predictors of abstract perceptions of scientific quality, benefit, and allocation of funding. Yet, they do not inform judgments about individual results. Therefore, polarization in the acceptance of specific results is not likely due to individual differences in perceived scientific uncertainty. Further, the direction of influence potentially could be reversed, such that perceived quality of scientific results could be used to influence perceptions about scientific research fields.

This glossary is a tool for clinicians who have to confront topics in which medical, scientific and technical jargon is closely linked. It provides definitions for the key concepts and terms of pharmaceutical care, clinical pharmacy, and research in the health care system in clinical settings. It includes items that are not particularly technical, but that should be part of the know-how of staff working in medical and scientific fields. In fact, the glossary can also help clinical technicians who want to understand the precise definition of scientific terms, which often do not coincide with the ones used in the practice setting. PRINCIPAL GOALS AND OBJECTIVES: The aim of this glossary is to aid in the development of more standardized and established terminology for clinical pharmacy, facilitate communication among different stakeholders and, ultimately, contribute to a higher-quality health care system. The glossary contains 165 definitions of concepts and principles in clinical pharmacy, and terms widely used in this field. The criteria for the inclusion of terms were specific applications in health promotion, or terms used in other fields that have a specific meaning or application when used in reference to clinical activity. The glossary arose from the need to standardize terminology in the scientific field. It was not intended as a comprehensive listing that would include all medical terms, but as a useful tool for clinical pharmacists working in this area, and for users who occasionally encounter unusual, often hard to understand, terminology.

The authors propose a novel bibilometric index, the reverberation index (r-index), as a comparative assessment tool for use in determining differential reverberation between scientific fields for a given scientific entity. Conversely, this may allow comparison of 2 similar scientific entities within a single scientific field. This index is calculated using a relatively simple 3-step process. Briefly, Thompson Reuters' Web of Science is used to produce a citation report for a unique search parameter (this may be an author, journal article, or topical key word). From this citation report, a list of citing journals is retrieved from which a weighted ratio of citation patterns across journals can be calculated. This r-index is then used to compare the reverberation of the original search parameter across different fields of study or wherever a comparison is required. The advantage of this novel tool is its ability to transcend a specific component of the scientific process. This affords application to a diverse range of entities, including an author, a journal article, or a topical key word, for effective comparison of that entity's reverberation within a scientific arena. The authors introduce the context for and applications of the r-index, emphasizing neurosurgical topics and journals for illustration purposes. It should be kept in mind, however, that the r-index is readily applicable across all fields of study.

Forthcoming human planetary exploration will require increased scientific return (both in real time and post-mission), longer surface stays, greater geographical coverage, longer and more frequent EVAs, and more operational complexities than during the Apollo missions. As such, there is a need to shift the nature of astronauts' scientific capabilities to something akin to an experienced terrestrial field scientist. To achieve this aim, the authors present a case that astronaut training should include an Apollo-style curriculum based on traditional field school experiences, as well as full immersion in field science programs. Herein we propose four Learning Design Principles (LDPs) focused on optimizing astronaut learning in field science settings. The LDPs are as follows: LDP#1: Provide multiple experiences: varied field science activities will hone astronauts' abilities to adapt to novel scientific opportunities LDP#2: Focus on the learner: fostering intrinsic motivation will orient astronauts towards continuous informal learning and a quest for mastery LDP#3: Provide a relevant experience - the field site: field sites that share features with future planetary missions will increase the likelihood that astronauts will successfully transfer learning LDP#4: Provide a social learning experience - the field science team and their activities: ensuring the field team includes members of varying levels of experience engaged in opportunities for discourse and joint problem solving will facilitate astronauts' abilities to think and perform like a field scientist. The proposed training program focuses on the intellectual and technical aspects of field science, as well as the cognitive manner in which field scientists experience, observe and synthesize their environment. The goal of the latter is to help astronauts develop the thought patterns and mechanics of an effective field scientist, thereby providing a broader base of experience and expertise than could be achieved from field school alone. This will enhance their ability to execute, explore and adapt as in-field situations require.
Teacher Field Research Experiences: Building and Maintaining the Passion for K-12 Science Education
NASA Astrophysics Data System (ADS)
Dunton, K.; Schonberg, S.
2006-12-01
Academic scientists and researchers are increasingly encouraged to develop connections with K-12 educators to promote scientific literacy and bring excitement into the classroom. Such partnerships carry long-term benefits to both teachers and researchers. Teachers gain the tools, confidence, and knowledge to develop research activities with their students that promote scientific inquiry, and researchers benefit from outreach activities that improve communication skills for sharing scientific knowledge with the public. Our K-12 programs have been field based under a theme of Classrooms Without Walls, to take advantage of our local marine environment and a long-term research program on the Alaskan Arctic coast. Our professional development programs for teachers have included the creation of an annual summer graduate level course (Application of Field Research Experiences for K-12 Science and Math Educators) as an introduction to scientific methodology, observation, and inquiry based learning. We provide graduate students as resources in classrooms and for field trip experiences and provide supplies and instrumentation to teachers for K-12 field projects. Finally, teachers have an opportunity to join our researchers to remote sites under various competitive programs that receive federal support (e.g. GK-12, ARMADA). We provide examples of our activities, which are based on recent needs assessment surveys of science teachers; these included development of content knowledge and providing students with opportunities to connect concepts with experiences. Our goal is to provide field experiences to teachers and students that enable them to relate science concepts to the real world.
Data Friction Meets Social Friction: Challenges for standardization in emerging fields of geoscience
NASA Astrophysics Data System (ADS)
Darch, P. T.
2017-12-01
Many interdisciplinary endeavors in the geosciences occur in emergent scientific fields. These fields are often characterized by heterogeneity of methods for production and collection of data, and by data scarcity. This paper presents findings about processes of methods standardization from a long-term case study of an emergent, data-scarce field, the deep subseafloor biosphere. Researchers come from many physical and life science backgrounds to study interactions between microbial life in the seafloor and the physical environment they inhabit. Standardization of methods for collecting data promises multiple benefits to this field, including: Addressing data scarcity through enabling greater data reuse and promoting better interoperability with large scale infrastructures; Fostering stronger collaborative links between researchers distributed across institutions and backgrounds. Ongoing standardization efforts in the field do not only involve scientific judgments about which among a range of methods is most efficient, least biased, or most reliable. Instead, these efforts also encounter multiple difficult social challenges, including: Lack of agreed upon criteria about how to judge competing methods: should efficiency, bias, or reliability take priority?; Lack of resources to carry out the work necessary to determine standards, particularly acute in emergent fields; Concerns that standardization is premature in such a new field, foreclosing the possibility of better methods being developed in the future; Concerns that standardization could prematurely shut down important scientific debates; Concerns among some researchers that their own work may become obsolete should the methods chosen as standard be different from their own. The success of these standardization efforts will depend on addressing both scientific and social dimensions, to ensure widespread acceptance among researchers in the field.

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.

A highly skilled public health workforce is needed for responding to health threats, and that workforce must be able to communicate its scientific findings effectively. We evaluated the scientific communication effectiveness of the Centers for Disease Control and Prevention's (CDC's) field-based Epidemic Intelligence Service officers (EISOs). A descriptive analysis of all scientific information products produced and submitted for institutional clearance by CDC's field-based EISOs during 2009-2014. The number of abstracts, journal manuscripts, Morbidity and Mortality Weekly Reports (MMWRs), and other information products approved by CDC during 2009-2014; the number of those products published; and of those published, the number cited in the scientific literature. During 2009-2014, a total of 152 field-based EISOs produced 835 scientific information products, including 437 abstracts, 261 manuscripts, and 103 MMWRs. The majority of scientific information products submitted for clearance were abstracts (52.3%), and infectious diseases (75.3%) constituted the majority of topics. Among the 103 MMWRs and 261 manuscripts cleared, 88 (85%) and 199 (76%) were published, respectively, with the majority also infectious disease-related. The 199 published manuscripts were cited in the scientific literature 2415 times, and the 88 published MMWRs were cited 1249 times. Field-based EISOs published their work in 74 different peer-reviewed medical and public health journals, with 54% published in journals with impact factors of 1 to 5. Field-based EISOs' publications are a measurable marker that reflects proficiency in epidemiology, written communication, and professionalism, and those publications are a direct reflection of EISOs' contribution to local and state health departments. Our study establishes a baseline for future evaluations of publication outcome of scientific information products by EISOs. Information released by EISOs provides health professionals with the scientific knowledge necessary for improving their practice and helps CDC achieve a broader societal, environmental, cultural, and economic impact.

Recent National Institutes of Health changes have focused attention on the potential scientific impact of research projects. Research with the excellent potential to change subsequent science or health care practice may have high scientific impact. Only rigorous studies that address highly significant problems can generate change. Studies with high impact may stimulate new research approaches by changing understanding of a phenomenon, informing theory development, or creating new research methods that allow a field of science to move forward. Research with high impact can transition health care to more effective and efficient approaches. Studies with high impact may propel new policy developments. Research with high scientific impact typically has both immediate and sustained influence on the field of study. The article includes ideas to articulate potential scientific impact in grant applications as well as possible dissemination strategies to enlarge the impact of completed projects.

Concern that "EMF" magnetic fields from power lines cause cancer.
Repacholi, Michael
2012-06-01
In 2002, the International Agency for Research on Cancer (IARC, 2002) categorized extremely low frequency (ELF) (including the power frequencies of 50 and 60 Hz) magnetic fields as "possibly carcinogenic to humans." That was based on pooled analyses of epidemiological research that reported an association between exposure to low-level magnetic fields and childhood leukemia. In 2007 a task group of scientific experts convened by the World Health Organization (WHO) acknowledged the IARC categorization but found that the laboratory studies and other research results did not support the association. Taking all evidence into account WHO reported that it could not confirm the existence of any health consequences from exposure to low-level magnetic fields. There remains continuing concern by some people that exposure to power frequency magnetic fields may cause adverse health effects, particularly childhood leukemia. Public health authorities need to fully understand the reasons for that ongoing concern and effective ways to address it. This paper describes what drives the concern, including how people perceive risks, how WHO and other public health authorities assess scientific research to determine whether health risks exist and the conclusions they have reached about power frequency magnetic fields. This paper also addresses the scientific basis of international exposure guidelines for power frequency magnetic fields and what precautionary measures are warranted to address the concern.

Recent technological developments in medicine, including modern radiology have promoted the impact of scientific researches on social life. The scientific outputs such as article and patents are products that show the scientists' attempt to access these achievements. In the current study, we evaluate the current situation of Iranian scientists in the field of radiology and compare it with the selected countries in terms of scientific papers. For this purpose, we used scientometric tools to quantitatively assess the scientific papers in the field of radiology. Radiology papers were evaluated in the context of medical field audit using retrospective model. We used the related databases of biomedical sciences for extraction of articles related to radiology. In the next step, the situation of radiology scientific products of the country were determined with respect to the under study regional countries. Results of the current study showed a ratio of 0.19% for Iranian papers in PubMed database published in 2009. In addition, in 2009, Iranian papers constituted 0.29% of the Scopus scientific database. The proportion of Iranian papers in the understudy region was 7.6%. To diminish the gap between Iranian scientific radiology papers and other competitor countries in the region and achievement of document 2025 goals, multifold effort of the society of radiology is necessary.

Vazquez, G.; Landeros, C. F.
2007-12-01
In recent years, bibliometric science has been frequently applied in the development and evaluation of scientific research. This work presents a bibliometric analysis for the research work performed in the field of geodesy "science of the measurement and mapping of the earth surface including its external gravity field". The objective of this work is to present a complete overview of the generated research on this field to assemble and study the most important publications occurred during the past seven years. The analysis was performed including the SCOPUS and WEB OF SCIENCE databases for all the geodetic scientific articles published between 2000 and 2006. The search profile was designed considering a strategy to seek for titles and article descriptors using the terms geodesy and geodetic and some other terms associated with the topics: geodetic surfaces, vertical measurements, reference systems and frames, modern space-geodetic techniques and satellite missions. Some preliminary results had been achieved specifically Bradford law of distribution for journals and education institutes, and Lotka's law for authors that also includes the cooperation between countries in terms of writing together scientific articles. In the particular case of distributions, the model suggested by Egghe (2002) was adopted for determining the cores.

The role of technology is an increasingly important resource in preparing students for the future. The Internet is a widely accessible tool. Technology has also made us more connected, allowing constant communication and instantaneous data sharing. Public utilities such as those found on the web, including blogs, are a means to convey scientific research in rapid, useful ways. This tool is ideal for newly emerging fields, allowing up-to-date collaboration and referencing of ongoing studies, as well as bringing students virtually into the field or laboratory through videos, pictures, and records of project work. Astrobiology is a high interest topic, integrating geology, chemistry, biology, and physics. Terrestrial Mars analog environments are compelling in that they shed light on unusual opportunities for diverse life in settings beyond Earth. For this study, the analog site locality is at the University of California-Davis McLaughlin Natural Reserve in the Coast Range Ophiolite, a portion of actively serpentinizing, uplifted oceanic material in northern California (see companion poster, McCann et al., Mineralogy of Surface Serpentinite Outcrops in the Coast Range Ophiolite: Implications for the Deep Biosphere and Astrobiology). Our research objective is to monitor the activity taking place within the subsurface biosphere through an interdisciplinary approach involving biogeochemists, microbiologists, organic geochemists, and geologists. The study of serpentinization with astrobiological ground-truthing is a relatively new and promising field. Scientific field procedures are constantly being modified as they are applied. In order to better collaborate study efforts, a daily field journal is being written, recording ideas, discussions, procedures, problems, solutions, and results. It serves as an informal report, including pictures and video clips of the field activity. The journal is maintained as an online blog for ease of use and accessibility, as well as public comment. Its secondary purpose is to serve as a resource oriented toward high school science classrooms interested in cutting edge scientific endeavors. Included are video interviews of each participating scientist, covering topics such as professional background, past studies, their parts in the ongoing project and what they hope to gain through this research. By piecing together the various scientific approaches with the procedural field work, I am simplifying the massive amount of details involved between proposing a project and having a presentable result. As a high school student, the enormity of research possibilities can be in awe-inspiring contrast with the precision of the end result. This blog is interlocking the important components of our field campaign so that the audience will understand better the tasks involved in the field of scientific research. It not only will bring clarity and realism to the scientific process, but will serve to convey the passion and life involved in the research by the people that love what they do.

An up-to-date progress of the international laser research and development is given in this article. The number of scientific publications and filed patents are considered as a figure of merit and based on these numbers the growth pace and important aspects are investigated. We have used the Science Finder Scholar search engine, which indexes more than 4000 journals, in different languages, and represents most significant published materials in laser science and engineering. The growth of the laser and related fields are described in terms of resulting scientific publications for the period of 1990-2003. The share of top nations in scientific publications, and in particular laser publications in terms of their gross domestic product (GDP) is presented. It is noted that the four countries including the USA, Japan, Germany and China have a laser publication contribution of 58.9% while the rest of the world including 189 countries contribute 41.1%. However, for the case of patent, which is a more important factor, these four countries hold a share of 90.1% while the remaining nations have a small share of 9.9%. The USA heads all the nations in the number of scientific publications, citations, and laser publications, however, in terms of accepted laser patents Japan shows a big lead. Scientific scopes of the laser systems are presented and some requirements to be met in each field are described. The key points in this field of research, which might be helpful in the future development of the laser technology are discussed.

Engineering a medical technology is a complex process, therefore it is important to include experts from different scientific fields. This is particularly true for the development of surgical technology, where the relevant scientific fields are surgery (medicine) and engineering (electrical engineering, mechanical engineering, computer science, etc.). Furthermore, the scientific field of human factors is important to ensure that a surgical technology is indeed functional, process-oriented, effective, efficient as well as user- and patient-oriented. Working in such trans- and inter-disciplinary teams can be challenging due to different working cultures. The intention of this paper is to propose an innovative cooperative working culture for the interdisciplinary field of computer-assisted surgery (CAS) based on more than ten years of research on the one hand and the interdisciplinary literature on working cultures and various organizational theories on the other hand. In this paper, a retrospective analysis of more than ten years of research work in inter- and trans-disciplinary teams in the field of CAS will be performed. This analysis is based on the documented observations of the authors, the study reports, protocols, lab reports and published publications. To additionally evaluate the scientific experience in an interdisciplinary research team, a literature analysis regarding scientific literature on trans- and inter-disciplinarity was performed. Own research and literature analyses were compared. Both the literature and the scientific experience in an interdisciplinary research team show that consensus finding is not always easy. It is, however, important to start trans- and interdisciplinary projects with a shared mental model and common goals, which include communication and leadership issues within the project teams, i.e. clear and unambiguous information about the individual responsibilities and objectives to attain. This is made necessary due to differing leadership cultures within the cooperating disciplines. Another research outcome is the relevance of a cooperative learning culture throughout the complete duration of the project. Based on this cooperation, new ideas and projects were developed, i.e. a training concept for surgical trainers including technological competence for surgeons. An adapted innovative paradigm for a cooperating working culture in CAS is based on a shared mental model and common goals from the very beginning of a project. All actors in trans- and inter-disciplinary teams need to be interested in cooperation. This will lead to a common view on patients and technology models. Copyright © 2015 Elsevier B.V.

The rapid growth of scientific publications necessitates new methods to understand the direction of scientific research within fields of study, ascertain the importance of particular groups, authors, or institutions, compute metrics that can determine the importance (centrality) of particular seminal papers, and provide insight into the social (collaboration) networks that are present. We present one such method based on analysis of citation networks, using the freely available CiteSpace Program. We use citation network analysis on three examples, including a single material that has been widely explored in the last decade (BiFeO 3), two small subfields with a minimal number ofmore » authors (flexoelectricity and Kitaev physics), and a much wider field with thousands of publications pertaining to a single technique (scanning tunneling microscopy). Interpretation of the analysis and key insights into the fields, such as whether the fields are experiencing resurgence or stagnation, are discussed, and author or collaboration networks that are prominent are determined. Such methods represent a paradigm shift in our way of dealing with the large volume of scientific publications and could change the way literature searches and reviews are conducted, as well as how the impact of specific work is assessed.« less

Armenia is rich in scientific sites, among which archaeological sites of scientific nature, modern scientific institutions and science related museums can be mentioned. Examples of archaeological sites are ancient observatories, petroglyphs having astronomical nature, as well as intangible heritage, such as Armenian calendars. Modern institutions having tools or laboratories which can be represented in terms of tourism, are considered as scientific tourism sites. Science related museums are Museum of science and technology, Space museum, Geological museum and other museums. Despite the fact, that scientific tourism is a new direction, it has great perspectives, and Armenia has a great potential in this field. It is very important to introduce Armenia from this angle, including scientific archaeological sites as well as modern institutions and museums. This article presents major scientific tourism centers of Armenia.

Although several studies have examined the contribution of specific countries, journals, and authors in different scientific disciplines, little is known about the contribution of different world countries, journals, and authors to scientific research in the field of "Spirituality, religion, and health" (S/R). The present study aims to analyze the last 15 years of research in the field of spirituality and religiousness (S/R) through a bibliometric analysis. Using the Pubmed database, we retrieved all articles related to S/R field for the period 1999-2013. We then estimated the total number of publications, number of articles published per year, articles published per country, journals with most publications in S/R field, most productive authors, and most used keywords. We found a growth of publications in the last years, most from the United States and the United Kingdom and published in the English language. Noteworthy, some developing countries such as India, Brazil, Israel, and Iran are at higher positions in this list. The S/R articles were published in journals embracing all fields of research, including high impact journals. In the present study, we took a closer look at the field of "Spirituality, religion, and health," showing that this field of research has been constantly growing and consolidating in the scientific community.

Interviews with key scientists who had conducted research on Severe Acute Respiratory Syndrome (SARS), together with analysis of media reports, documentaries and other literature published during and after the SARS epidemic, revealed many interesting aspects of the nature of science (NOS) and scientific inquiry in contemporary scientific research in the rapidly growing field of molecular biology. The story of SARS illustrates vividly some NOS features advocated in the school science curriculum, including the tentative nature of scientific knowledge, theory-laden observation and interpretation, multiplicity of approaches adopted in scientific inquiry, the inter-relationship between science and technology, and the nexus of science, politics, social and cultural practices. The story also provided some insights into a number of NOS features less emphasised in the school curriculum—for example, the need to combine and coordinate expertise in a number of scientific fields, the intense competition between research groups (suspended during the SARS crisis), the significance of affective issues relating to intellectual honesty and the courage to challenge authority, the pressure of funding issues on the conduct of research and the ‘peace of mind’ of researchers, These less emphasised elements provided empirical evidence that NOS knowledge, like scientific knowledge itself, changes over time. They reflected the need for teachers and curriculum planners to revisit and reconsider whether the features of NOS currently included in the school science curriculum are fully reflective of the practice of science in the 21st century. In this paper, we also report on how we made use of extracts from the news reports and documentaries on SARS, together with episodes from the scientists’ interviews, to develop a multimedia instructional package for explicitly teaching the prominent features of NOS and scientific inquiry identified in the SARS research.

Concerning the public discussion on animal experiments using primates, various research fields are demonstrated where non-human primates are necessary for certain scientific reasons at this time. Non-human Primates are used in Germany mainly in regulatory toxicology and pharmaceutical safety studies.A small amount is disposed in different fields of biological or biomedical basic research. This includes in particular neurosciences and infection research. 2006 New and Old World monkeys were needed in Germany in 2005. No chimpanzees are used anymore as laboratory animals in Germany since many years. Several examples are presented to demonstrate that certain research fields need non-human primates as laboratory animals in the foreseeable future.

Monticone, Francesco; Alù, Andrea

The field of metamaterials has opened landscapes of possibilities in basic science, and a paradigm shift in the way we think about and design emergent material properties. In many scenarios, metamaterial concepts have helped overcome long-held scientific challenges, such as the absence of optical magnetism and the limits imposed by diffraction in optical imaging. As the potential of metamaterials, as well as their limitations, become clearer, these advances in basic science have started to make an impact on several applications in different areas, with far-reaching implications for many scientific and engineering fields. At optical frequencies, the alliance of metamaterials with the fields of plasmonics and nanophotonics can further advance the possibility of controlling light propagation, radiation, localization and scattering in unprecedented ways. In this review article, we discuss the recent progress in the field of metamaterials, with particular focus on how fundamental advances in this field are enabling a new generation of metamaterial, plasmonic and nanophotonic devices. Relevant examples include optical nanocircuits and nanoantennas, invisibility cloaks, superscatterers and superabsorbers, metasurfaces for wavefront shaping and wave-based analog computing, as well as active, nonreciprocal and topological devices. Throughout the paper, we highlight the fundamental limitations and practical challenges associated with the realization of advanced functionalities, and we suggest potential directions to go beyond these limits. Over the next few years, as new scientific breakthroughs are translated into technological advances, the fields of metamaterials, plasmonics and nanophotonics are expected to have a broad impact on a variety of applications in areas of scientific, industrial and societal significance.

We aimed to evaluate the current status of scientific production in the field of substance use and addiction in Iran, to determine its trend and pattern during a 5 years period (2008-2012). Using relevant keywords, we searched three international databases (Web of Science, Medline, and Scopus) and two local databases (SID and Iranmedex) to locate the papers published in the field of addiction by Iranian researchers during 2008-2012. The results indicated a significant increase in the number of studies published in the field during the 5 years study period, with more than half of the papers published in the last 2 years. Results also indicated that over half (53.5%) of the papers were published in Persian-language Iranian Journals, but the rate of increase in the number of papers published in English was slightly higher than that of Persian ones. Opioid substances were found to be the topic of approximately 75% of the papers. Studies on key topics, including national surveys, evaluation of current programs, addiction in women and children, and so forth, were found to be highly lacking. Results suggested a significant growth in the scientific production of Iran in the field of substance use and addiction. However, considering the significance of substance use and dependence in the country, and compared to the scientific production of developed countries, the amount of research conducted in the field of addiction in Iran is still limited.

Mapping the knowledge utilization field in nursing from 1945 to 2004: a bibliometric analysis.
Scott, Shannon D; Profetto-McGrath, Joanne; Estabrooks, Carole A; Winther, Connie; Wallin, Lars; Lavis, John N
2010-12-01
The field of knowledge utilization has been hampered by several issues including: the synonymous use of multiple terms with little attempt at definition precision; an overexamination of knowledge utilization as product, rather than a process; and a lack of progress to cross disciplinary boundaries to advance knowledge development. In order to address the challenges and current knowledge gaps in the knowledge utilization field in nursing, a comprehensive picture of the current state of the field is required. Bibliometric analyses were used to map knowledge utilization literature in nursing as an international field of study, and to identify the structure of its scientific community. Analyses of bibliographic data for 433 articles from the period 1945-2004 demonstrated three trends: (1) there has been significant recent growth and interest in this field, (2) the structure of the scientific knowledge utilization community is evolving, and (3) the Web of Science does not index the majority of journals where this literature is published. In order to enhance the accessibility and profile of this literature, and nursing's scientific literature at large, we encourage the International Academy of Nursing Editors to work collaboratively to increase the number of journals indexed in the Web of Science. ©2010 Sigma Theta Tau International.
Mapping the Evolution of Scientific Fields
Herrera, Mark; Roberts, David C.; Gulbahce, Natali
2010-01-01
Despite the apparent cross-disciplinary interactions among scientific fields, a formal description of their evolution is lacking. Here we describe a novel approach to study the dynamics and evolution of scientific fields using a network-based analysis. We build an idea network consisting of American Physical Society Physics and Astronomy Classification Scheme (PACS) numbers as nodes representing scientific concepts. Two PACS numbers are linked if there exist publications that reference them simultaneously. We locate scientific fields using a community finding algorithm, and describe the time evolution of these fields over the course of 1985–2006. The communities we identify map to known scientific fields, and their age depends on their size and activity. We expect our approach to quantifying the evolution of ideas to be relevant for making predictions about the future of science and thus help to guide its development. PMID:20463949

Studies have shown that undergraduate participation in research opportunities strengthens the retention of students in STEM fields. Increasing students' confidence levels in their scientific abilities, aiding in the development of their scientific identity, and strengthening their sense of belonging to a scientific community have been cited as important contributing factors. Research field stations offer unique advantages that amplify these benefits by challenging students to plan and work in the field, enhancing networking opportunities with multi-disciplinary professionals from numerous institutions and hierarchical levels, and creating a stronger sense of belonging and comradery within a science community. The USC Wrigley Institute for Environmental Studies' (WIES) Research Experiences for Undergraduates (REU) program is an 8-week program that begins on the main USC campus in Los Angeles and moves to a marine field station on Catalina Island during weeks 2-7, before returning to the mainland to complete the last week of the program. This unique model provides REU students with an opportunity to become integrated into faculty mentors' labs on the main campus, while exposing them to life as a researcher at a field station, both of which contribute significantly to the students' development as a scientist. Here, we present the WIES REU model and include a discussion of benefits and challenges to this unique infrastructure.

The sharing of scientific data reinforces open scientific inquiry; it encourages diversity of analysis and opinion while promoting new research and facilitating the education of next generations of scientists. In this article, we present an initiative for the development of a repository containing continuous electrocardiographic information and their associated clinical information. This information is shared with the worldwide scientific community in order to improve quantitative electrocardiology and cardiac safety. First, we present the objectives of the initiative and its mission. Then, we describe the resources available in this initiative following three components: data, expertise and tools. The Data available in the Telemetric and Holter ECG Warehouse (THEW) includes continuous ECG signals and associated clinical information. The initiative attracted various academic and private partners whom expertise covers a large list of research arenas related to quantitative electrocardiography; their contribution to the THEW promotes cross-fertilization of scientific knowledge, resources, and ideas that will advance the field of quantitative electrocardiography. Finally, the tools of the THEW include software and servers to access and review the data available in the repository. To conclude, the THEW is an initiative developed to benefit the scientific community and to advance the field of quantitative electrocardiography and cardiac safety. It is a new repository designed to complement the existing ones such as Physionet, the AHA-BIH Arrhythmia Database, and the CSE database. The THEW hosts unique datasets from clinical trials and drug safety studies that, so far, were not available to the worldwide scientific community. PMID:20863512

NMR images of laser polarized 3He gas were obtained at 21 G using a simple, homebuilt instrument. At such low fields magnetic resonance imaging (MRI) of thermally polarized samples (e.g., water) is not practical. Low-field noble gas MRI has novel scientific, engineering, and medical applications. Examples include portable systems for diagnosis of lung disease, as well as imaging of voids in porous media and within metallic systems.

Gendermetrics.NET: a novel software for analyzing the gender representation in scientific authoring.
Bendels, Michael H K; Brüggmann, Dörthe; Schöffel, Norman; Groneberg, David A
2016-01-01
Imbalances in female career promotion are believed to be strong in the field of academic science. A primary parameter to analyze gender inequalities is the gender authoring in scientific publications. Since the presently available data on gender distribution is largely limited to underpowered studies, we here develop a new approach to analyze authors' genders in large bibliometric databases. A SQL-Server based multiuser software suite was developed that serves as an integrative tool for analyzing bibliometric data with a special emphasis on gender and topographical analysis. The presented system allows seamless integration, inspection, modification, evaluation and visualization of bibliometric data. By providing an adaptive and almost fully automatic integration and analysis process, the inter-individual variability of analysis is kept at a low level. Depending on the scientific question, the system enables the user to perform a scientometric analysis including its visualization within a short period of time. In summary, a new software suite for analyzing gender representations in scientific articles was established. The system is suitable for the comparative analysis of scientific structures on the level of continents, countries, cities, city regions, institutions, research fields and journals.

The American Geophysical Union (AGU), a scientific society of >60,000 members worldwide, has established a set of scientific integrity and professional ethics guidelines for the actions of its members, for the governance of the union in its internal activities, and for the operations and participation in its publications and scientific meetings. More recently AGU has undertaken actions to help address the issue of harassment in the sciences and other work climate issues; and, where applied more broadly as a code of standard behavior, will help address tangential issues of diversity and inclusion. This presentation will highlight the proposed policy changes and additional resources now in place, as they apply to field and lab environments. Progress to date and remaining challenges of this effort will be discussed, including AGU's work to provide additional program strength in the areas of Ethics, Diversity and Inclusion.

The scientific results of the Pioneer Saturn encounter with Saturn are summarized. The Pioneer mission was designed to image the planet, its satellites and rings, and measure its particulate environment and the magnetic field and photon and charged particle radiation by means of 11 operational scientific instruments and its 2.293-GHz telemetry carrier signal. Principle results of the mission include the discovery of an additional ring and a previously unidentified satellite, the further characterization of the physical properties of Saturn and its magnetic field, and the description of the planetary magnetosphere. The successful completion of the mission demonstrated the ability of spacecraft such as Voyager 1 and 2 to survive the particle environments of Saturn's rings and trapped radiation environments, and Pioneer Saturn is expected to continue transmitting information on the interplanetary medium and the solar wind interaction with the interstellar medium until the mid-1980's.

Bacterial Chemotaxis: The Early Years of Molecular Studies
Hazelbauer, Gerald L.
2014-01-01
This review focuses on the early years of molecular studies of bacterial chemotaxis and motility, beginning in the 1960s with Julius Adler's pioneering work. It describes key observations that established the field and made bacterial chemotaxis a paradigm for the molecular understanding of biological signaling. Consideration of those early years includes aspects of science seldom described in journals: the accidental findings, personal interactions, and scientific culture that often drive scientific progress.

As the body of scientific knowledge in a discipline increases, there is pressure for specialization. Fields spawn subfields that then become entities in themselves that promote further specialization. The process by which scientists join specialized groups has remarkable similarities to the guild system of the middle ages. The advantages of specialization of science include efficiency, the establishment of normative standards, and the potential for greater rigor in experimental research. However, specialization also carries risks of monopoly, monotony, and isolation. The current tendency to judge scientific work by the impact factor of the journal in which it is published may have roots in overspecialization, as scientists are less able to critically evaluate work outside their field than before. Scientists in particular define themselves through group identity and adopt practices that conform to the expectations and dynamics of such groups. As part of our continuing analysis of issues confronting contemporary science, we analyze the emergence and consequences of specialization in science, with a particular emphasis on microbiology, a field highly vulnerable to balkanization along microbial phylogenetic boundaries, and suggest that specialization carries significant costs. We propose measures to mitigate the detrimental effects of scientific specialism.

1994-01-01
Virtual environment technology is a new way of approaching the interface between computers and humans. Emphasizing display and user control that conforms to the user's natural ways of perceiving and thinking about space, virtual environment technologies enhance the ability to perceive and interact with computer generated graphic information. This enhancement potentially has a major effect on the field of scientific visualization. Current examples of this technology include the Virtual Windtunnel being developed at NASA Ames Research Center. Other major institutions such as the National Center for Supercomputing Applications and SRI International are also exploring this technology. This talk will be describe several implementations of virtual environments for use in scientific visualization. Examples include the visualization of unsteady fluid flows (the virtual windtunnel), the visualization of geodesics in curved spacetime, surface manipulation, and examples developed at various laboratories.

Eddy covariance and surface renewal measurements were used to estimate evapotranspiration (ET) over a variety of crop fields in the Sacramento-San Joaquin River Delta during the 2016 growing season. However, comparing and evaluating multiple measurement systems and methods for determining ET was focused upon at a single alfalfa site. The eddy covariance systems included two systems for direct measurement of latent heat flux: one using a separate sonic anemometer and an open path infrared gas analyzer and another using a combined system (Campbell Scientific IRGASON). For these methods, eddy covariance was used with measurements from the Campbell Scientific CSAT3, the LI-COR 7500a, the Campbell Scientific IRGASON, and an additional R.M. Young sonic anemometer. In addition to those direct measures, the surface renewal approach included several energy balance residual methods in which net radiation, ground heat flux, and sensible heat flux (H) were measured. H was measured using several systems and different methods, including using multiple fast-response thermocouple measurements and using the temperatures measured by the sonic anemometers. The energy available for ET was then calculated as the residual of the surface energy balance equation. Differences in ET values were analyzed between the eddy covariance and surface renewal methods, using the IRGASON-derived values of ET as the standard for accuracy.
Concentration of the Most-Cited Papers in the Scientific Literature: Analysis of Journal Ecosystems
Ioannidis, John P. A.
2006-01-01
Background A minority of scientific journals publishes the majority of scientific papers and receives the majority of citations. The extent of concentration of the most influential articles is less well known. Methods/Principal Findings The 100 most-cited papers in the last decade in each of 21 scientific fields were analyzed; fields were considered as ecosystems and their “species” (journal) diversity was evaluated. Only 9% of journals in Journal Citation Reports had published at least one such paper. Among this 9%, half of them had published only one such paper. The number of journals that had published a larger number of most-cited papers decreased exponentially according to a Lotka law. Except for three scientific fields, six journals accounted for 53 to 94 of the 100 most-cited papers in their field. With increasing average number of citations per paper (citation density) in a scientific field, concentration of the most-cited papers in a few journals became even more prominent (p<0.001). Concentration was unrelated to the number of papers published or number of journals available in a scientific field. Multidisciplinary journals accounted for 24% of all most-cited papers, with large variability across fields. The concentration of most-cited papers in multidisciplinary journals was most prominent in fields with high citation density (correlation coefficient 0.70, p<0.001). Multidisciplinary journals had published fewer than eight of the 100 most-cited papers in eight scientific fields (none in two fields). Journals concentrating most-cited original articles often differed from those concentrating most-cited reviews. The concentration of the most-influential papers was stronger than the already prominent concentration of papers published and citations received. Conclusions Despite a plethora of available journals, the most influential papers are extremely concentrated in few journals, especially in fields with high citation density. Existing multidisciplinary journals publish selectively most-cited papers from fields with high citation density. PMID:17183679

Improving scientific literacy is a goal in the United States. Scientists from the United States are often expected to present research findings in ways that are meaningful and accessible to the general public, including K-12 students. PolarTREC - Teachers and Researchers Exploring and Collaborating, a program funded by the National Science Foundation, partners teachers with scientists in the Arctic and Antarctica. Teachers communicate the research to general audiences on a regular basis. After the field experience, they then create classroom-ready lessons to relay the science exploration into science curriculum. In this presentation, secondary level educators, will share their experiences with being part of field research teams in the Arctic and Antarctica, and their strategies for bringing current science research into the classroom and aligning lessons with Next Generation Science Standards (NGSS). Topics include an overview on using polar science to teach about climate change, application of field research techniques to improve students' understanding of scientific investigation methodology, phenology observations, soil porosity and permeability, litter decomposition, effect of sunlight on release of carbon dioxide from thawing permafrost, and understanding early life on Earth by studying stromatolites in Antarctica.

ABSTRACT On rare occasions in the history of science, remarkable discoveries transform human society and forever alter mankind’s view of the world. Examples of such discoveries include the heliocentric theory, Newtonian physics, the germ theory of disease, quantum theory, plate tectonics and the discovery that DNA carries genetic information. The science philosopher Thomas Kuhn famously described science as long periods of normality punctuated by times of crisis, when anomalous observations culminate in revolutionary changes that replace one paradigm with another. This essay examines several transformative discoveries in the light of Kuhn’s formulation. We find that each scientific revolution is unique, with disparate origins that may include puzzle solving, serendipity, inspiration, or a convergence of disparate observations. The causes of revolutionary science are varied and lack an obvious common structure. Moreover, it can be difficult to draw a clear distinction between so-called normal and revolutionary science. Revolutionary discoveries often emerge from basic science and are critically dependent on nonrevolutionary research. Revolutionary discoveries may be conceptual or technological in nature, lead to the creation of new fields, and have a lasting impact on many fields in addition to the field from which they emerge. In contrast to political revolutions, scientific revolutions do not necessarily require the destruction of the previous order. For humanity to continue to benefit from revolutionary discoveries, a broad palette of scientific inquiry with a particular emphasis on basic science should be supported. PMID:26933052

LFS was an educational outreach adventure which brought the excitement of astronomical exploration on NASA's Kuiper Airborne Observatory (KAO) to a nationwide audience of children, parents and children through live, interactive television, broadcast from the KAO at an altitude of 41,000 feet during an actual scientific observing mission. The project encompassed three KAO flights during the fall of 1995, including a short practice mission, a daytime observing flight between Moffett Field, California to Houston, Texas, and a nighttime mission from Houston back to Moffett Field. The University of Chicago infrared research team participated in planning the program, developing auxiliary materials including background information and lesson plans, developing software which allowed students on the ground to control the telescope and on-board cameras via the Internet from the Adler Planetarium in Chicago, and acting as on-camera correspondents to explain and answer questions about the scientific research conducted during the flights.
Experience-based Learning in Acadia National Park: a Successful, Long-running, Model Field Course
NASA Astrophysics Data System (ADS)
Connaughton, M.
2015-12-01
This two-week field course has been offered alternate summers since 2000 in Acadia National Park on Mount Desert Island, Maine and addresses the geological history, physical and biological oceanography and principles of community ecology applicable to terrestrial and/or marine communities of coastal Maine. The course is often transformative and deeply meaningful to the students, many of whom have limited travel experience. The essential components of experience-based learning are well represented in this class with multiple opportunities for abstract conceptualization, active experimentation, concrete hands-on experiences and reflective observation built into the course. Each day begins with a lecture introducing concepts, which are then made concrete though daily field trips (4-8 hours in duration) into the park that include rigorous hiking, some kayaking and one commercial nature cruise. Field trips include hands-on experience with lecture concepts, on-site lessons in field methods, and data collection for independent projects. Each field trip is tied to a specific independent project, which are generated by the instructor, but self-selected by the students. Every student is actively involved in data collection during each field trip, with one student in charge of the collection each day. Daily guided journaling in three parts (scientific, personal and creative) and evening discussions provide ample opportunity for the student to reflect on the scientific content of the course, examine their personal reactions to what they have experienced and to be creative, sharing prior experiences, prior learning and their personalities. The course includes two exams, each following a week of lecture and field experiences. Independent research projects include the production of a manuscript-formatted report complete with statistical analysis of the data and a literature-based discussion of the conclusions. The combination of experiential reinforcement of concepts, abundant opportunity for written and spoken reflection, the beauty of the setting, the challenges of working in the field and the resultant bonding of the students and instructors provide a highly effective and unforgettable learning experience.

Climate change in high northern latitudes is unfolding faster than anywhere else on Earth, resulting in widespread changes in landscape structure and ecosystem function in the Arctic-Boreal Region (ABR). Recognizing its sensitivity, vulnerability and global importance, national- and international-level scientific efforts are now advancing our ability to observe, understand and model the complex, multi-scale processes that drive the ABR's natural and social systems. Long at the edge of our mental map of the world, environmental change in the ABR is increasingly becoming the focus of numerous policy discussions at the highest levels of decision-making. To improve our understanding of environmental change and its impacts in the ABR, the Terrestrial Ecology Program of the U.S. National Aeronautics and Space Administration (NASA) is planning its next major field campaign for Western Canada and Alaska. The field campaign will be based on the Arctic-Boreal Vulnerability Experiment (ABoVE) concept as described in the Revised Executive Summary from the ABoVE Scoping Study Report. The original Scoping Study Report provided the proof-of-concept demonstration of scientific importance and feasibility for this large-scale study. In early 2013, NASA announced the selection of the ABoVE Science Definition Team, which is charged with developing the Concise Experiment Plan for the campaign. Here, we outline the conceptual basis for ABoVE and present the compelling rationale explaining the scientific and societal importance of the study. We present the current status of the planning process, which includes development of the science questions to drive ABoVE research; the study design for the field campaign to address them; and the interagency and international collaborations necessary for implementation. The ABoVE study will focus on 1) developing a fuller understanding of ecosystem vulnerability to climate change in the ABR, and 2) providing the scientific information required to develop options for societal responses to the impacts of these changes. The field campaign will emphasize research that integrates data collected by airborne and spaceborne sensors with information obtained from field studies and ground-based observations. Other key components of ABoVE research include the process-level analyses, scientific syntheses, and modeling needed for understanding ecosystem responses and societal implications.

Launching ScienceCentral is the first step for free access or open access academic scientific journals of all languages to leap to the world, including scientific journals from Croatia.
Widening the adoption of workflows to include human and human-machine scientific processes

Scientific workflows capture knowledge in the form of technical recipes to access and manipulate data that help scientists manage and reuse established expertise to conduct their work. Libraries of scientific workflows are being created in particular fields, e.g., Bioinformatics, where combined with cyber-infrastructure environments that provide on-demand access to data and tools, result in powerful workbenches for scientists of those communities. The focus in these particular fields, however, has been more on automating rather than documenting scientific processes. As a result, technical barriers have impeded a wider adoption of scientific workflows by scientific communities that do not rely as heavily on cyber-infrastructure and computing environments. Semantic Abstract Workflows (SAWs) are introduced to widen the applicability of workflows as a tool to document scientific recipes or processes. SAWs intend to capture a scientists’ perspective about the process of how she or he would collect, filter, curate, and manipulate data to create the artifacts that are relevant to her/his work. In contrast, scientific workflows describe the process from the point of view of how technical methods and tools are used to conduct the work. By focusing on a higher level of abstraction that is closer to a scientist’s understanding, SAWs effectively capture the controlled vocabularies that reflect a particular scientific community, as well as the types of datasets and methods used in a particular domain. From there on, SAWs provide the flexibility to adapt to different environments to carry out the recipes or processes. These environments range from manual fieldwork to highly technical cyber-infrastructure environments, i.e., such as those already supported by scientific workflows. Two cases, one from Environmental Science and another from Geophysics, are presented as illustrative examples.

2013-04-01
Soils is one of the science investigation areas in the Global learning and Observations to Benefit the Environment (GLOBE), an international science and education program (112 countries) that teaches primary and secondary students to learn science by doing science. For each area of investigation GLOBE provides background information, measurement protocols and learning activities compiled as a chapter in the GLOBE Teacher's Guide. Also provided are data sheets and field guides to assist in the accurate collection of data as well as suggestions of scientific instruments and calibration methods. Teachers learn GLOBE scientific measurement protocols at professional development workshops led by scientists and educators, who then engage their students in soil studies that also contribute to ongoing science investigations. Students enter their data on the GLOBE website and can access their data as well as other data contributed by students from other parts of the world. Soil characterization measurements carried out in the field include site description, horizon depths, soil structure, soil color, soil consistence, soil texture, roots, rocks and carbonates. Other field measurements are soil temperature and soil moisture monitoring while the following measurements are carried out in the classroom or laboratory: gravimetric soil moisture, bulk density, particle density, particle size distribution, pH and soil fertility (nitrogen, phosphorus and potassium). Learning activities provide support for preparing students to do the measurements and for better understanding of science concepts. Many countries in GLOBE have adopted standards for education including science education with commonalities among them. For the Teacher's Guide, the National Science Education Standards published by the US National Academy of Sciences, selected additional content standards that GLOBE scientists and educators feel are appropriate and the National Geography Standards prepared by the (US) National Education Standards Project, are being used. Educational objectives for students include gaining scientific inquiry abilities in addition to understanding scientific concepts. The Soils chapter also includes some suggestions for managing students in the field and classroom. A new protocol has also been developed by the Seasons and Biomes project, one of the GLOBE earth system science projects. Active Layer monitoring uses a Frost Tube that measures when and how deeply soil freezes and is currently being used in more than 200 sites in Alaska. Teachers have successfully implemented soil studies in their curriculum and have used it to teach about the science process.
Pioneers on the Astrosociological Frontier: Introduction to the First Symposium on Astrosociology
NASA Astrophysics Data System (ADS)
Pass, Jim
2009-03-01
Astrosociology is a relatively new multidisciplinary field that scientifically investigates astrosocial phenomena (i.e., social, cultural, and behavioral patterns related to space exploration and related issues). The "astrosociological frontier" represents an analogous framework to that of space as the "final frontier," as both territories are quite empty of human activity and ripe for exploration. This focus on the astrosociological frontier provides insights about the need for a social-scientific field to place the human dimension in its proper place alongside familiar space community concerns such as engineering. The astrosociological frontier refers to the lack of development of astrosociology as a scientific field—or anything like it earlier during the space age. It includes both the 1) unoccupied "landscape" in academia characterized by the lack of astrosociology in its curricula and 2) dearth of space research focused on social-scientific (i.e., astrosociological) topics both inside and outside of traditional academia in collaboration with traditional space community members and the new space entrepreneurs. Within academia, the "frontier" is characterized by a lack of courses, programs, and departments dedicated to astrosociology. In the future, proponents of this new field expect the astrosociological frontier to become characterized by a growing number of "settlements" in curricula across the country and world. As things stand, however, the early "astrosociological pioneers" include those who seek to explore these underappreciated issues within academic and professional climates that discourage them from pursuing their interests. Thus, the "1st Symposium on Astrosociology" at the 2009 SPESIF conference represents an important expedition consisting of pioneering participants willing to venture into a little-explored territory with the goal of developing astrosociology.

ABSTRACT Objective A systematic review was conducted to analyze Brazilian scientific and technological production related to the dental materials field over the past 50 years. Material and Methods This study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (Prisma) statement. Searches were performed until December 2014 in six databases: MedLine (PubMed), Scopus, LILACS, IBECS, BBO, and the Cochrane Library. Additionally, the Brazilian patent database (INPI - Instituto Nacional de Propriedade Industrial) was screened in order to get an overview of Brazilian technological development in the dental materials field. Two reviewers independently analyzed the documents. Only studies and patents related to dental materials were included in this review. Data regarding the material category, dental specialty, number of documents and patents, filiation countries, and the number of citations were tabulated and analyzed in Microsoft Office Excel (Microsoft Corporation, Redmond, Washington, United States). Results A total of 115,806 studies and 53 patents were related to dental materials and were included in this review. Brazil had 8% affiliation in studies related to dental materials, and the majority of the papers published were related to dental implants (1,137 papers), synthetic resins (681 papers), dental cements (440 papers), dental alloys (392 papers) and dental adhesives (361 papers). The Brazilian technological development with patented dental materials was smaller than the scientific production. The most patented type of material was dental alloys (11 patents), followed by dental implants (8 patents) and composite resins (7 patents). Conclusions Dental materials science has had a substantial number of records, demonstrating an important presence in scientific and technological development of dentistry. In addition, it is important to approximate the relationship between academia and industry to expand the technological development in countries such as Brazil. PMID:27383712

Does the world need a scientific society for research on how to improve healthcare?
2012-01-01
In this editorial, we reflect on the arguments for starting a scientific society focused on research on how to improve healthcare. This society would take an inclusive approach to what constitutes healthcare. For instance, it should include mental health healthcare, treatment for substance abuse, the work of allied health professions, and preventive healthcare. The society would be open to researchers from all traditions. Thus, we take an inclusive approach to what constitutes scientific research, as long as it uses rigorous methods, is focused on improving healthcare, and aims at knowledge that can be transferred across settings. The society would primarily target scientific researchers but would invite others with an interest in this area of research, regardless of their discipline, position, field of application, or group affiliation (e.g., improvement science, behavioral medicine, knowledge translation). A society would need fruitful collaboration with related societies and organizations, which may include having combined meetings. Special links may be developed with one or more journals. A website to provide information on relevant resources, events, and training opportunities is another key activity. It would also provide a voice for the field at funding agencies, political arenas, and similar institutions. An organizational structure and financial resources are required to develop and run these activities. Our aim is to start an international debate, to discover if we can establish a shared vision across academics and stakeholders engaged with creating scientific knowledge on how to improve healthcare. We invite readers to express their views in the online questionnaire accessed by following the URL link provided at the end of the editorial. PMID:22376988

Systematic assessments of the scientific production can optimize resource allocation and increase research productivity in Brazil. The aim of this study was to evaluate the profile and scientific production of researchers in the field of Cardiology who have fellowship in Medicine provided by the Conselho Nacional de Desenvolvimento Científico e Tecnológico. The curriculum Lattes of 33 researchers with active fellowships from 2006 to 2008 were included in the analysis. The variables of interest were: gender, affiliation, tutoring of undergraduate, masters and PhD students, and scientific production and its impact. : There was predominance of males (72.7%) and of fellowship level 2 (56.4%). Three states of the Federation were responsible for 94% of the researchers: SP (28; 71.8%), RS (4; 10.3%), e RJ (3; 9.1%). Four institutions are responsible for about 82% of researchers: USP (13; 39.4%), UNESP (5; 15.2%), UFRGS (4; 12.1%) e UNIFESP (3; 9.1%). During all academic careers, the researchers published 2.958 journal articles, with a mean of 89 articles per researcher. Of total, 55% and 75% were indexed at Web of Science and Scopus databases, respectively. The researchers received a total of 19648 citations at the database Web of Science, with a median of 330 citations per researcher (IQ = 198-706). The average number of citations per article was 13.5 citations (SD = 11.6). Our study has shown that researchers in the field of cardiology have a relevant scientific production. The knowledge of the profile of researchers in the field of Cardiology will probably enable effective strategies to qualitatively improve the scientific output of Brazilian researchers.

The unique geo-environment offered in Capitol Reef National Park and its surrounding areas has a long-standing history of inspiring geological scientific exploration. The Capitol Reef Field Station was established in 2008 as part of collaboration between the National Park and Utah Valley University in order to support teaching and research of the natural environment found within the park and on the Colorado Plateau. The facility itself situated deep within the park, well off any public road system offers state of the art alternative energy and sustainable construction and makes extensive use of passive heating and cooling, in order to maintain its status of being "off-grid." The field station is a 6200 square foot complex of classrooms and dormitories supporting university level education and field studies of the Colorado Plateau. The complex includes a classroom and dining area, professional kitchen, and two separate dormitories, which can sleep up to 24 overnight visitors, while the daytime usage can accommodate up to 40 visitors. The vision of the facility is to support teaching and research toward responsible, respectful, and sustainable stewardship of the natural world - including Interdisciplinary learning between arts and sciences Student internships and service learning in collaboration with the National Park Service Field-based scientific research (as well as inventorying and assessing Park ecosystems changes) Field training in scientific research Collaboration between National Park Service scientists and local, regional, and national institutions The park is situated at 38°N 249°E at elevations greater than 2000 m in Southern Utah. In contrast to the more famous neighboring sister parks such as Zion and Bryce Canyon National Parks, which are in relatively close proximity to large road systems and cities, Capitol Reef offers what is believed to be the darkest night sky in the US. The culmination of features creates an ideal location for studies of the faint upper atmospheric airglow emissions. This presentation details the upper atmospheric undergraduate educational program at UVU, and will also include a section regarding the newly established interdisciplinary air pollution educational program, and how communities outside of UVU can use the facility.

The accelerated development of digital libraries and archives, in tandem with efficient search engines and the computational ability to retrieve and parse massive amounts of information, are making it possible to quantify the time evolution of scientific literatures. These data are but one piece of the tangible recorded evidence of the processes whereby scientists create and exchange information in their journeys towards the generation of knowledge. As such, these tools provide a proxy with which to study our ability to innovate. Innovation has often been linked with prosperity and growth and, consequently, trying to understand what drives scientific innovation ismore » of extreme interest. Identifying sets of population characteristics, factors, and mechanisms that enable scientific communities to remain at the cutting edge, accelerate their growth, or increase their ability to re-organize around new themes or research topics is therefore of special significance. Yet generating a quantitative understanding of the factors that make scientific fields arise and/or become more or less productive is still in its infancy. This is precisely the type of knowledge most needed for promoting and sustaining innovation. Ideally, the efficient and strategic allocation of resources on the part of funding agencies and corporations would be driven primarily by knowledge of this type. Early steps have been taken toward such a quantitative understanding of scientific innovation. Some have focused on characterizing the broad properties of relevant time series, such as numbers of publications and authors in a given field. Others have focused on the structure and evolution of networks of coauthorship and citation. Together these types of studies provide much needed statistical analyses of the structure and evolution of scientific communities. Despite these efforts, however, crucial elements of prediction have remained elusive. Building on many of these earlier insights, we provide here a coarse-grained approach to modeling the time-evolution of scientific fields mathematically, through adaptive models of contagion. That is, our models are inspired by epidemic contact processes, but take into account the social interactions and processes whereby scientific ideas spread - social interactions gleaned from close empirical study of historical cases. Variations in model parameters can increase or hamper the speed at which a field develops. In this way, models for the spread of 'infectious' ideas can be used to identify pressure points in the process of innovation that may allow for the evaluation of possible interventions by those responsible for promoting innovation, such as funding agencies. This report is organized as follows: Section 2 introduces and discusses the population model used here to describe the dynamics behind the establishment of scientific fields. The approach is based on a succinct (coarse) description of contact processes between scientists, and is a simplified version of a general class of models developed in the course of this work. We selected this model based primarily on its ability to treat a wide range of data patterns efficiently, across several different scientific fields. We also describe our methods for estimating parameter values, our optimization techniques used to match the model to data, and our method of generating error estimates. Section 3 presents brief accounts of six case studies of scientific evolution, measured by the growth in number of active authors over time, and shows the results of fitting our model to these data, including extrapolations to the near future. Section 4 discusses these results and provides some perspectives on the values and limitations of the models used. We also discuss topics for further research which should improve our ability to predict (and perhaps influence) the course of future scientific research. Section 5 provides more detail on the broad class of epidemic models developed as part of this project.« less

The growth rate of scientific publication has been studied from 1907 to 2007 using available data from a number of literature databases, including Science Citation Index (SCI) and Social Sciences Citation Index (SSCI). Traditional scientific publishing, that is publication in peer-reviewed journals, is still increasing although there are big differences between fields. There are no indications that the growth rate has decreased in the last 50 years. At the same time publication using new channels, for example conference proceedings, open archives and home pages, is growing fast. The growth rate for SCI up to 2007 is smaller than for comparable databases. This means that SCI was covering a decreasing part of the traditional scientific literature. There are also clear indications that the coverage by SCI is especially low in some of the scientific areas with the highest growth rate, including computer science and engineering sciences. The role of conference proceedings, open access archives and publications published on the net is increasing, especially in scientific fields with high growth rates, but this has only partially been reflected in the databases. The new publication channels challenge the use of the big databases in measurements of scientific productivity or output and of the growth rate of science. Because of the declining coverage and this challenge it is problematic that SCI has been used and is used as the dominant source for science indicators based on publication and citation numbers. The limited data available for social sciences show that the growth rate in SSCI was remarkably low and indicate that the coverage by SSCI was declining over time. National Science Indicators from Thomson Reuters is based solely on SCI, SSCI and Arts and Humanities Citation Index (AHCI). Therefore the declining coverage of the citation databases problematizes the use of this source.

A key objective of this paper is to describe some major challenges and opportunities facing the behavioral medicine field in the current decade. Amidst current U.S. statistics that present a sobering image of the nation’s health, there have been a number of notable achievements in the behavioral medicine field that span the scientific/health continuum. Yet, many of these achievements have received little notice by the public and decision makers. A case is presented for the potential of scientific narrative for presenting behavioral medicine evidence in ways that engage attention and compel action. Additional areas for behavioral medicine engagement include expanding interdisciplinary connections into new arenas, continuing the growth of activities involving emerging technologies, building international connections, and engaging with policy. Finally, the fundamental importance of an integrated behavioral medicine field that plays an active role in supporting and advancing its members and the field as a whole is discussed. PMID:24096957

Improving Public Perception of Behavior Analysis.
Freedman, David H
2016-05-01
The potential impact of behavior analysis is limited by the public's dim awareness of the field. The mass media rarely cover behavior analysis, other than to echo inaccurate negative stereotypes about control and punishment. The media instead play up appealing but less-evidence-based approaches to problems, a key example being the touting of dubious diets over behavioral approaches to losing excess weight. These sorts of claims distort or skirt scientific evidence, undercutting the fidelity of behavior analysis to scientific rigor. Strategies for better connecting behavior analysis with the public might include reframing the field's techniques and principles in friendlier, more resonant form; pushing direct outcome comparisons between behavior analysis and its rivals in simple terms; and playing up the "warm and fuzzy" side of behavior analysis.

ScienceCentral, a free or open access, full-text archive of scientific journal literature at the Korean Federation of Science and Technology Societies, was under test in September 2013. Since it is a Journal Article Tag Suite-based full text database, extensible markup language files of all languages can be presented, according to Unicode Transformation Format 8-bit encoding. It is comparable to PubMed Central: however, there are two distinct differences. First, its scope comprises all science fields; second, it accepts all language journals. Launching ScienceCentral is the first step for free access or open access academic scientific journals of all languages to leap to the world, including scientific journals from Croatia. PMID:24266292

Geoscience education is key for the understanding of our home, the planet Earth. The Lagos Ciência Viva Science Centre (CCVL) in Portugal develops various geoscience activities including astronomy sessions, geology, paleontology and oceanography field trips, complementary primary school classes, seminars and numerous workshops for a public ranging from pre-schoolers to seniors . Our experience in geoscience communication and informal education also includes a formal partnership with a research centre from the University of the Algarve, the CIMA - Centre for Marine and Environmental Research, through the project MOSES, which focuses on sand transport along crenulated coasts. Based on the project goals, methods and results, the CCVL team designed a communication and outreach plan including a seminar, a field trip and a workshop, to alert for the subjects of coastal erosion and management, both highly relevant in the Algarve. This partnership was highly beneficial for both parts as it facilitated the communication of a scientific project to the public, while the CCVL had the opportunity to update and expand its educational offer. This type of interaction between universities/research institutes and science centres/museums allows scientists to focus on their research work, reducing their need to invest in communication, and provides good and updated scientific contents to science communicators, ensuring a direct channel between scientific research and the public.

The aim of the paper is to overview the leading information processing domain in Russia and Eastern Europe, namely All Russian Institute for Scientific and Technical Information (VINITI ) of the Russian Academy of Sciences. Russian science structure is different from that in the Western Europe and the US. The main aim of VINITI is to collect, process and disseminate scientific information on various fields of science and technology, published in 70 countries in 40 languages, selected from books, journals, conference proceedings, and patents. A special attention is given to the journal selection and depositing manuscripts (a kind of grey literature), an important source for Russian research. VINITI has created the largest database containing about 30 million records dating back to 1980. About 80,000-100,000 new records are added monthly. VINITI publishes the Journal Abstract (JA) on 19 fields of science, including medicine, containing about a million publications annually. Two thirds of these records are foreign and 36.7% – Russian sources. PMID:23322964

The main aim of VINITI is to collect, process and disseminate scientific information on various fields of science and technology, published in 70 countries in 40 languages, selected from books, journals, conference proceedings, and patents. A special attention is given to the journal selection and depositing manuscripts (a kind of grey literature), an important source for Russian research. VINITI has created the largest database containing about 30 million records dating back to 1980. About 80,000-100,000 new records are added monthly. VINITI publishes the Journal Abstract (JA) on 19 fields of science, including medicine, containing about a million publications annually. Two thirds of these records are foreign and 36.7% - Russian sources.

This review reports the Brazilian history in astrobiology, as well as the first delineation of a vision of the future development of the field in the country, exploring its abundant biodiversity, highly capable human resources and state-of-the-art facilities, reflecting the last few years of stable governmental investments in science, technology and education, all conditions providing good perspectives on continued and steadily growing funding for astrobiology-related research. Brazil is growing steadily and fast in terms of its worldwide economic power, an effect being reflected in different areas of the Brazilian society, including industry, technology, education, social care and scientific production. In the field of astrobiology, the country has had some important landmarks, more intensely after the First Brazilian Workshop on Astrobiology in 2006. The history of astrobiology in Brazil, however, is not so recent and had its first occurrence in 1958. Since then, researchers carried out many individual initiatives across the country in astrobiology-related fields, resulting in an ever growing and expressive scientific production. The number of publications, including articles and theses, has particularly increased in the last decade, but still counting with the effort of researchers working individually. That scenario started to change in 2009, when a formal group of Brazilian researchers working with astrobiology was organized, aiming at congregating the scientific community interested in the subject and to promote the necessary interactions to achieve a multidisciplinary work, receiving facilities and funding from the University de Sao Paulo and other funding agencies.
Trajectory Optimization for Missions to Small Bodies with a Focus on Scientific Merit.
Englander, Jacob A; Vavrina, Matthew A; Lim, Lucy F; McFadden, Lucy A; Rhoden, Alyssa R; Noll, Keith S
2017-01-01
Trajectory design for missions to small bodies is tightly coupled both with the selection of targets for a mission and with the choice of spacecraft power, propulsion, and other hardware. Traditional methods of trajectory optimization have focused on finding the optimal trajectory for an a priori selection of destinations and spacecraft parameters. Recent research has expanded the field of trajectory optimization to multidisciplinary systems optimization that includes spacecraft parameters. The logical next step is to extend the optimization process to include target selection based not only on engineering figures of merit but also scientific value. This paper presents a new technique to solve the multidisciplinary mission optimization problem for small-bodies missions, including classical trajectory design, the choice of spacecraft power and propulsion systems, and also the scientific value of the targets. This technique, when combined with modern parallel computers, enables a holistic view of the small body mission design process that previously required iteration among several different design processes.

Leibundgut, B.; Berger, J.-P.

An observatory system like the VLT/I requires careful scientific planning for operations and future instruments. Currently the ESO optical/near-infrared facilities include four 8m telescopes, four (movable) 1.8m telescopes used exclusively for interferometry, two 4m telescopes and two survey telescopes. This system offers a large range of scientific capabilities and setting the corresponding priorities depends good community interactions. Coordinating the existing and planned instrumentation is an important aspect for strong scientific return. The current scientific priorities for the VLT and VLTI are pushing for the development of the highest angular resolution imaging and astrometry, integral field spectroscopy and multi-object spectroscopy. The ESO 4m telescopes on La Silla will be dedicated to time domain spectroscopy and exo-planet searches with highly specialized instruments. The next decade will also see a significant rise in the scientific importance of massive ground and space-based surveys. We discuss how future developments in astronomical research could shape the VLT/I evolution.

As in other fields of medicine, scientific production in the field of dentistry has significant placement. This study aimed at quantitatively and qualitatively evaluating Iranian researchers' scientific output in the field of dentistry and determining their contribution in each of dentistry subfields and branches. This research was a scientometric study that applied quantitative and qualitative indices of Web of Science (WoS). Research population consisted of927indexed documents published under the name of Iran in the time span of 1993-2012 which were extracted from WoS on 10 March 2013. The Mann-Whitney test and Pearson correlation coefficient were used to data analyses in SPSS 19. 777 (83. 73%) of indexed items of all scientific output in WoS were scientific articles. The highest growth rate of scientific productionwith90% belonged to endodontic sub field. The correlation coefficient test showed that there was a significant positive relationship between the number of documents and their publication age (P < 0. 0001). There was a significant difference between the mean number of published articles in the first ten- year (1993-2003) and that of the second one (2004-2013), in favor of the latter (P = 0. 001). The distribution frequencies of scientific production in various subfields of dentistry were very different. It needs to reinforce the infrastructure for more balanced scientific production in the field and its related subfields.

Raphael Meldola FRS (1849-1915) was professor of chemistry at the City and Guilds Technical College in Finsbury. He was a colleague and close friend of Silvanus Phillips Thompson FRS (1851-1916), the college principal and professor of physics. This paper follows an earlier one on Thompson and the making of his career. It is intended to illustrate further the ways in which scientists of Meldola and Thompson's generation gained advancement within the scientific community. Meldola had interests beyond chemistry, including a serious interest in field entomology. In this he had several well-known mentors including Alfred Russel Wallace and Charles Darwin. The paper, which includes much new information derived from archival work, is presented as six thematic narratives related, among other things, to chemical and technical education, dye chemistry, the Royal Society solar eclipse expedition of 1875, natural history and Darwinism, field clubs, learned societies, and the honouring of scientists. Together these narratives illustrate a generalist/voluntarist career pattern that came to an end with the First World War.

Research Infrastructure and Scientific Collections: The Supply and Demand of Scientific Research
NASA Astrophysics Data System (ADS)
Graham, E.; Schindel, D. E.
2016-12-01
Research infrastructure is essential in both experimental and observational sciences and is commonly thought of as single-sited facilities. In contrast, object-based scientific collections are distributed in nearly every way, including by location, taxonomy, geologic epoch, discipline, collecting processes, benefits sharing rules, and many others. These diffused collections may have been amassed for a particular discipline, but their potential for use and impact in other fields needs to be explored. Through a series of cross-disciplinary activities, Scientific Collections International (SciColl) has explored and developed new ways in which the supply of scientific collections can meet the demand of researchers in unanticipated ways. From cross-cutting workshops on emerging infectious diseases and food security, to an online portal of collections, SciColl aims to illustrate the scope and value of object-based scientific research infrastructure. As distributed infrastructure, the full impact of scientific collections to the research community is a result of discovering, utilizing, and networking these resources. Examples and case studies from infectious disease research, food security topics, and digital connectivity will be explored.
Scientific Ethics: A New Approach.
Menapace, Marcello
2018-06-04
Science is an activity of the human intellect and as such has ethical implications that should be reviewed and taken into account. Although science and ethics have conventionally been considered different, it is herewith proposed that they are essentially similar. The proposal set henceforth is to create a new ethics rooted in science: scientific ethics. Science has firm axiological foundations and searches for truth (as a value, axiology) and knowledge (epistemology). Hence, science cannot be value neutral. Looking at standard scientific principles, it is possible to construct a scientific ethic (that is, an ethical framework based on scientific methods and rules), which can be applied to all sciences. These intellectual standards include the search for truth (honesty and its derivatives), human dignity (and by reflection the dignity of all animals) and respect for life. Through these it is thence achievable to draft a foundation of a ethics based purely on science and applicable beyond the confines of science. A few applications of these will be presented. Scientific ethics can have vast applications in other fields even in non scientific ones.

Approach of Decision Making Based on the Analytic Hierarchy Process for Urban Landscape Management
NASA Astrophysics Data System (ADS)
Srdjevic, Zorica; Lakicevic, Milena; Srdjevic, Bojan
2013-03-01
This paper proposes a two-stage group decision making approach to urban landscape management and planning supported by the analytic hierarchy process. The proposed approach combines an application of the consensus convergence model and the weighted geometric mean method. The application of the proposed approach is shown on a real urban landscape planning problem with a park-forest in Belgrade, Serbia. Decision makers were policy makers, i.e., representatives of several key national and municipal institutions, and experts coming from different scientific fields. As a result, the most suitable management plan from the set of plans is recognized. It includes both native vegetation renewal in degraded areas of park-forest and continued maintenance of its dominant tourism function. Decision makers included in this research consider the approach to be transparent and useful for addressing landscape management tasks. The central idea of this paper can be understood in a broader sense and easily applied to other decision making problems in various scientific fields.

The considerable increase in using mobile communication which will increase when new technologies, such as UMTS, are introduced has resulted in further public interest concerning the possible health risks from electromagnetic fields of cellular phone networks. In view of evaluating the scientific state-of-the art, it has been shown that based on the available scientific results, the individual risk in view of proved health consequences is considered low. There are, however, indications of biological effects of high-frequency electromagnetic fields, even at intensities below the currently applied limit values or recommendations for limit values. Although the health relevance of these effects is still unclear, they give reason to precautionary measures with the object to minimise possible health risks which might affect a large number of persons. The precautionary measures recommended by the Federal Office for Radiation Protection include three principles: 1. Exposure of the general public to electromagnetic fields should be as low as possible. This applies for both the fixed parts of cellular phone networks and for mobile phones. 2. The population should be informed of risks in an objective and comprehensive way and be involved in the decisions on the construction and operation of cellular phone networks. 3. Scientific uncertainties should be reduced by means of well-directed research programmes. These precautionary measures and the significance of limit values are explained below.
The Neuropsychoanalytic Approach: Using Neuroscience as the Basic Science of Psychoanalysis.
Johnson, Brian; Flores Mosri, Daniela
2016-01-01
Neuroscience was the basic science behind Freud's psychoanalytic theory and technique. He worked as a neurologist for 20 years before being aware that a new approach to understand complex diseases, namely the hysterias, was needed. Solms coined the term neuropsychoanalysis to affirm that neuroscience still belongs in psychoanalysis. The neuropsychoanalytic field has continued Freud's original ideas as stated in 1895. Developments in psychoanalysis that have been created or revised by the neuropsychoanalysis movement include pain/relatedness/opioids, drive, structural model, dreams, cathexis, and dynamic unconscious. Neuroscience has contributed to the development of new psychoanalytic theory, such as Bazan's (2011) description of anxiety driven by unconscious intentions or "phantoms." Results of adopting the "dual aspect monism" approach of idiographic psychoanalytic clinical observation combined with nomothetic investigation of related human phenomena include clarification and revision of theory, restoration of the scientific base of psychoanalysis, and improvement of clinical treatments. By imbricating psychoanalytic thinking with neuroscience, psychoanalysts are also positioned to make contributions to neuroscience research. Freud's original Project for a Scientific Psychology/Psychology for Neurologists can be carried forward in a way that moves psychoanalysis into the twenty-first century as a core contemporary science (Kandel, 1999). Neuroscience as the basic science of psychoanalysis both improves the field, and enhances its scientific and cultural status.
User-friendly solutions for microarray quality control and pre-processing on ArrayAnalysis.org

Quality control (QC) is crucial for any scientific method producing data. Applying adequate QC introduces new challenges in the genomics field where large amounts of data are produced with complex technologies. For DNA microarrays, specific algorithms for QC and pre-processing including normalization have been developed by the scientific community, especially for expression chips of the Affymetrix platform. Many of these have been implemented in the statistical scripting language R and are available from the Bioconductor repository. However, application is hampered by lack of integrative tools that can be used by users of any experience level. To fill this gap, we developed a freely available tool for QC and pre-processing of Affymetrix gene expression results, extending, integrating and harmonizing functionality of Bioconductor packages. The tool can be easily accessed through a wizard-like web portal at http://www.arrayanalysis.org or downloaded for local use in R. The portal provides extensive documentation, including user guides, interpretation help with real output illustrations and detailed technical documentation. It assists newcomers to the field in performing state-of-the-art QC and pre-processing while offering data analysts an integral open-source package. Providing the scientific community with this easily accessible tool will allow improving data quality and reuse and adoption of standards. PMID:23620278

Recent progress in the field of sequencing and analysis has led to a tremendous spike in data and the development of data science tools. One of the outcomes of this scientific progress is development of numerous databases which are gaining popularity in all disciplines of biology including sericulture. As economically important organism, silkworms are studied extensively for their numerous applications in the field of textiles, biomaterials, biomimetics, etc. Similarly, host plants, pests, pathogens, etc. are also being probed to understand the seri-resources more efficiently. These studies have led to the generation of numerous seri-related databases which are extremely helpful for the scientific community. In this article, we have reviewed all the available online resources on silkworm and its related organisms, including databases as well as informative websites. We have studied their basic features and impact on research through citation count analysis, finally discussing the role of emerging sequencing and analysis technologies in the field of seri-data science. As an outcome of this review, a web portal named SeriPort, has been created which will act as an index for the various sericulture-related databases and web resources available in cyberspace.

Evolution and convergence of the patterns of international scientific collaboration.
Coccia, Mario; Wang, Lili
2016-02-23
International research collaboration plays an important role in the social construction and evolution of science. Studies of science increasingly analyze international collaboration across multiple organizations for its impetus in improving research quality, advancing efficiency of the scientific production, and fostering breakthroughs in a shorter time. However, long-run patterns of international research collaboration across scientific fields and their structural changes over time are hardly known. Here we show the convergence of international scientific collaboration across research fields over time. Our study uses a dataset by the National Science Foundation and computes the fraction of papers that have international institutional coauthorships for various fields of science. We compare our results with pioneering studies carried out in the 1970s and 1990s by applying a standardization method that transforms all fractions of internationally coauthored papers into a comparable framework. We find, over 1973-2012, that the evolution of collaboration patterns across scientific disciplines seems to generate a convergence between applied and basic sciences. We also show that the general architecture of international scientific collaboration, based on the ranking of fractions of international coauthorships for different scientific fields per year, has tended to be unchanged over time, at least until now. Overall, this study shows, to our knowledge for the first time, the evolution of the patterns of international scientific collaboration starting from initial results described by literature in the 1970s and 1990s. We find a convergence of these long-run collaboration patterns between the applied and basic sciences. This convergence might be one of contributing factors that supports the evolution of modern scientific fields.

Sharma, Prabodh Chander; Bansal, Kushal Kumar; Deep, Aakash; Pathak, Meenakshi
2017-01-01
Severity of microbial infections and escalating resistance towards antibiotics has created a deep necessity for discovery of novel anti-infective agents. Heterocyclic chemistry of benzothiazole has become one of the most prolific areas in the field of drug discovery and development that has attracted great attention in recent time due to its increasing importance in the field of pharmaceuticals. The importance of benzothiazole and derivatives as potential antimicrobial agents has been well established and a large number of papers have been published in this regard. The present communication is an earnest attempt to review the chemistry, synthetic aspects including click chemistry and antimicrobial activities of benzothiazole derivatives reported in recent scientific literature. The scientific information of this manuscript may be worthwhile in encouraging the prospective researchers working on this heterocyclic scaffold.

The study covers seven subfields of traditional Chinese medicine identification, quality standard, Chinese medicine cultivation, harvest processing of TCM, market development and resource protection and resource management, as well as 82 widely used Chinese medicine species, such as Ginseng and Radix Astragali. One hundred and fifteen domain authority experts were selected based on the data of high-yield authors and high-cited authors. The database system platform "Skilled Scientific and Technological Personnel in the field of Traditional Chinese Medicine Resource Science-Chinese papers" was established. This platform successfully provided the retrieval result of the personnel, output of paper, and their core research team by input the study field, year, and Chinese medicine species. The investigation provides basic data of scientific and technological personnel in the field of traditional Chinese medicine resource science for administrative agencies and also evidence for the selection of scientific and technological personnel and construction of scientific research teams.

We physics teachers must broaden our focus from physics for physicists and other scientists to physics for all. The reason, as the American Association for the Advancement of Science puts it, is that "[w]ithout a scientifically literate population, the outlook for a better world is not promising." Physics for all (including the first course for scientists) should be conceptual, not technical. It should describe the universe as we understand it today, including special and general relativity, quantum physics, modern cosmology, nuclear physics, the standard model of particles and interactions, and quantum fields. Many science writers have shown that this description is possible. It should emphasize the scientific process and include such societal topics as global warming, nuclear weapons, and pseudoscience, because citizens need to vote intelligently on such issues.

A considerable number of areas of bioscience, including gene and drug discovery, metabolic engineering for the biotechnological improvement of organisms, and the processes of natural and directed evolution, are best viewed in terms of a ‘landscape’ representing a large search space of possible solutions or experiments populated by a considerably smaller number of actual solutions that then emerge. This is what makes these problems ‘hard’, but as such these are to be seen as combinatorial optimisation problems that are best attacked by heuristic methods known from that field. Such landscapes, which may also represent or include multiple objectives, are effectively modelled in silico, with modern active learning algorithms such as those based on Darwinian evolution providing guidance, using existing knowledge, as to what is the ‘best’ experiment to do next. An awareness, and the application, of these methods can thereby enhance the scientific discovery process considerably. This analysis fits comfortably with an emerging epistemology that sees scientific reasoning, the search for solutions, and scientific discovery as Bayesian processes. PMID:22252984

Computational issues are becoming increasingly critical for virtually all fields of geoscience. This includes the development of improved algorithms and models, strategies for implementing high-performance computing, or the management and visualization of the large datasets provided by an ever-growing number of environmental sensors. Such issues are central to scientific fields as diverse as geological modeling, Earth observation, geophysics or climatology, to name just a few. Related computational advances, across a range of geoscience disciplines, are the core focus of Computers & Geosciences, which is thus a truly multidisciplinary journal.

Microgravity is a unique environment for materials and biotechnology processing. Microgravity minimizes or eliminates some of the effects that occur in one g. This can lead to the production of new materials or crystal structures. It is important to understand the processes that create these new materials. Thus, experiments are designed so that optical data collection can take place during the formation of the material. This presentation will discuss scientific application of optical instruments at MSFC. These instruments include a near-field scanning optical microscope, a miniaturized holographic system, and a phase-shifting interferometer.

Health Resort Medicine, Balneology, Medical Hydrology and Climatology are not fully recognised as independent medical specialties at a global international level. Analysing the reasons, we can identify both external (from outside the field) and internal (from inside the field) factors. External arguments include, e.g. the lack of scientific evidence, the fact that Balneotherapy and Climatotherapy is not used in all countries, and the fact that Health Resort Medicine, Balneology, Medical Hydrology and Climatology focus only on single methods and do not have a comprehensive concept. Implicit barriers are the lack of international accepted terms in the field, the restriction of being allowed to practice the activities only in specific settings, and the trend to use Balneotherapy mainly for wellness concepts. Especially the implicit barriers should be subject to intense discussions among scientists and specialists. This paper suggests one option to tackle the problem of implicit barriers by making a proposal for a structure and description of the medical field, and to provide some commonly acceptable descriptions of content and terminology. The medical area can be defined as "medicine in health resorts" (or "health resort medicine"). Health resort medicine includes "all medical activities originated and derived in health resorts based on scientific evidence aiming at health promotion, prevention, therapy and rehabilitation". Core elements of health resort interventions in health resorts are balneotherapy, hydrotherapy, and climatotherapy. Health resort medicine can be used for health promotion, prevention, treatment, and rehabilitation. The use of natural mineral waters, gases and peloids in many countries is called balneotherapy, but other (equivalent) terms exist. Substances used for balneotherapy are medical mineral waters, medical peloids, and natural gases (bathing, drinking, inhalation, etc.). The use of plain water (tap water) for therapy is called hydrotherapy, and the use of climatic factors for therapy is called climatotherapy. Reflecting the effects of health resort medicine, it is important to take other environmental factors into account. These can be classified within the framework of the ICF (International Classification of Functioning, Disability and Health). Examples include receiving health care by specialised doctors, being well educated (ICF-domain: e355), having an environment supporting social contacts (family, peer groups) (cf. ICF-domains: d740, d760), facilities for recreation, cultural activities, leisure and sports (cf. ICF-domain: d920), access to a health-promoting atmosphere and an environment close to nature (cf. ICF-domain: e210). The scientific field dealing with health resort medicine is called health resort sciences. It includes the medical sciences, psychology, social sciences, technical sciences, chemistry, physics, geography, jurisprudence, etc. Finally, this paper proposes a systematic international discussion of descriptions in the field of Health Resort Medicine, Balneology, Medical Hydrology and Climatology, and discusses short descriptive terms with the goal of achieving internationally accepted distinct terms. This task should be done via a structured consensus process and is of major importance for the publication of scientific results as well as for systematic reviews and meta-analyses.

Discovering: Students' meanings for research
NASA Astrophysics Data System (ADS)
Rymer, John Ewan
The call for science education reforms in the mid-1980s resulted in the implementation of a new Alberta senior high school science curriculum in 1992. The reformed curriculum reflected the call for increased authentic practice in the sciences. Part of my interpretation of this curriculum included a month long field biology research project. The students' scientific understandings while involved in this project have been a source of wonder and curiosity for me. As teacher researcher, I sought to interpret the meanings students held for scientific research as they progressed through their self-directed investigations. In an urban high school two of my Biology 20 classes comprised of a total of fifty-four students were involved in this study. Using data collected from student questionnaire responses, student field notebooks and recorded conversations my interpretations were developed. Based on these interpretations it appeared that students' understandings of research altered slightly through the course of the field project. Initially, I interpreted students' meanings for scientific research to include the notion that an independent external world exists which may be methodologically studied. Research was both purposeful and personal, seeking to discover new knowledge through the use of advanced technologies. Over the course of the biology project the students' meanings came to include the sense that research involved dealing with the uncertainty of novelty. Research became dynamic in nature and was seen to be never ending. It became apparent from students' conversations with me that students were aware school social structures and responded to the research project through their understanding of these structures. The potential benefits desired in the reformers' call for authentic scientific practice may have been subverted to a degree by the students' acceptance of school social structures and their underlying discourse. As a result, the implementation of authentic science within the parameters of contemporary school discourse is questioned. I also realized my personal connection to the discourse and structures of schooling. As a result, my initial assumptions and practices in the biology project's implementation had to be reconsidered. This is one of the benefits of teacher research considered in my reflections.

Cultural Astronomy is the reflection of sky events in various fields of nations' culture. In foreign literature, this field is also called "Astronomy in Culture" or "Astronomy and Culture". Cultural astronomy is the set of interdisciplinary fields studying the astronomical systems of current or ancient societies and cultures. It is manifested in Religion, Mythology, Folklore, Poetry, Art, Linguistics and other fields. During the past few decades interdisciplinary and multidisciplinary sciences have become the main incentive for the development of science. While studying astronomical topics in various areas of culture interesting discoveries have been occurred; such topics are widely used in folklore and other genres of literature, painting, architecture and music. Ancient astronomy, chronologies and calendars created on the basis of astronomical knowledge, Astrolinguistics and other fields play an important role in culture and national heritage. There are a number of organizations related to "Astronomy in Culture", appropriate specialists are being prepared, in this area conferences are being organized and papers are being published in professional and scientific-popular journals. Astronomy has also a leading role in scientific tourism, scientific journalism and in general science pularization and popular science dissemination, as well as social awareness and world perception. All these led to the idea of holding a Young Researchers conference with the subject on "Cultural Astronomy in Armenian Highland". Conference was held on June 20-23, 2016 in Armenian National Academy of Sciences. Among the participants there were astronomers, philosophers, historians, archeologists, specialists of literature, linguists, culturologists, experts in tourism and other fields. The opening session of the conference was attended by the president of NAS RA acad. Radik Martirosyan, NAS RA Academician-secretary of the Department of Armenology and Social Sciences acad. Yuri Suvaryan, ambassadors of foreign countries in Armenia, Presidents of RA Creative Unions, scientists, young researchers and journalists. The last sessions of the conference were held in the "Metsamor" Historical-Archeological Museum-Reserve, Art academy of Byurakan and Byurakan Astrophysical Observatory. The meeting is focused on Armenian archaeoastronomy and cultural astronomy, including many creations related to astronomical knowledge; calendars, rock art, mythology, etc. On the other hand, this subject is rather poorly developed in Armenia; there are only individual studies on various related issues (especially many studies related to Anania Shirakatsi) but not coordinated actions to manage this important field of investigation. The meeting is aimed at the development of problems of interdisciplinary sciences in Armenia and preparation of a basis for further possible collaborations by means of presentations of available modern knowledge in various areas of culture by experts from different professions and by joint discussions. A number of thematic sessions were held: Cultural Astronomy, Archaeoastronomy, Scientific Tourism & Scientific Journalism, Astronomical Education & Amauter Astronomy, Invited and contributed talks were presented by reknown and young researchers. The present Proceedings includes most of the talks. We hope that the Proceedings will be an interesting and valuable resource for many professionals and broad mass of readers.

The inability of physiologists to effect change in fisheries management has been the source of frustration for many decades. Close collaboration between fisheries managers and researchers has afforded our interdisciplinary team an unusual opportunity to evaluate the emerging impact that physiology can have in providing relevant and credible scientific advice to assist in management decisions. We categorize the quality of scientific advice given to management into five levels based on the type of scientific activity and resulting advice (notions, observations, descriptions, predictions and prescriptions). We argue that, ideally, both managers and researchers have concomitant but separate responsibilities for increasing the level of scientific advice provided. The responsibility of managers involves clear communication of management objectives to researchers, including exact descriptions of knowledge needs and researchable problems. The role of the researcher is to provide scientific advice based on the current state of scientific information and the level of integration with management. The examples of scientific advice discussed herein relate to physiological research on the impact of high discharge and water temperature, pathogens, sex and fisheries interactions on in-river migration success of adult Fraser River sockeye salmon (Oncorhynchus nerka) and the increased understanding and quality of scientific advice that emerges. We submit that success in increasing the quality of scientific advice is a function of political motivation linked to funding, legal clarity in management objectives, collaborative structures in government and academia, personal relationships, access to interdisciplinary experts and scientific peer acceptance. The major challenges with advancing scientific advice include uncertainty in results, lack of integration with management needs and institutional caution in adopting new research. We hope that conservation physiologists can learn from our experiences of providing scientific advice to management to increase the potential for this growing field of research to have a positive influence on resource management.

Gender equity and equality on Korean student scientists: A life history narrative study
NASA Astrophysics Data System (ADS)
Hur, Changsoo
Much research, including that by Koreans (e.g., Mo, 1999), agrees on two major points relating to the inequitable and unequal condition of women in the scientific community: (1) the fact that the under-representation of women in the scientific community has been taken for granted for years (e.g., Rathgeber, 1998), and (2) documenting women's lives has been largely excluded in women's studies (e.g., Sutton, 1998). The basis for the design of this study relates to the aforementioned observations. This study addresses two major research questions: how do social stereotypes exist in terms of gender equity and equality in the South Korean scientific and educational fields, and how do these stereotypes influence women and men's socializations, in terms of gender equity and equality, in the South Korean scientific and educational fields? To investigate the research questions, this qualitative study utilizes a life history narrative approach in examining various theoretical perspectives, such as critical theory, post-structuralism, and postmodernism. Through the participants' perceptions and experiences in the scientific community and in South Korean society, this study fords gendered stereotypes, practices, and socializations in school, family, and the scientific community. These findings demonstrate asymmetric gendered structures in South Korea. Moreover, with the comparison among male and female participants, this study shows how they perceive and experience differently in school, family, and the scientific community. This study attempts to understand the South Korean scientific community as represented by four student scientists through social structures. Education appears to function significantly as an hegemonic power in conveying legitimating ideologies. This process reproduces man-centered social structures, especially in the scientific community. This suggests that to emancipate women's under-representations in the scientific community, educational administrators and teachers should carefully consider gendered practices, stereotypes, and socialization in science classes. There have been significant findings of educative authenticity criteria (Guba & Lincoln, 1989) that stimulate the needs of future studies on gender, especially women in the scientific community in general and, more specifically, in South Korea. These findings suggest the importance of active involvement by women participants to enhance a more detailed examination, by women's studies, of the scientific community.
Simulation of Martian EVA at the Mars Society Arctic Research Station

Pletser, V.; Zubrin, R.; Quinn, K.
The Mars Society has established a Mars Arctic Research Station (M.A.R.S.) on Devon Island, North of Canada, in the middle of the Haughton crater formed by the impact of a large meteorite several million years ago. The site was selected for its similarities with the surface of the Mars planet. During the Summer 2001, the MARS Flashline Research Station supported an extended international simulation campaign of human Mars exploration operations. Six rotations of six person crews spent up to ten days each at the MARS Flashline Research Station. International crews, of mixed gender and professional qualifications, conducted various tasks as a Martian crew would do and performed scientific experiments in several fields (Geophysics, Biology, Psychology). One of the goals of this simulation campaign was to assess the operational and technical feasibility of sustaining a crew in an autonomous habitat, conducting a field scientific research program. Operations were conducted as they would be during a Martian mission, including Extra-Vehicular Activities (EVA) with specially designed unpressurized suits. The second rotation crew conducted seven simulated EVAs for a total of 17 hours, including motorized EVAs with All Terrain Vehicles, to perform field scientific experiments in Biology and Geophysics. Some EVAs were highly successful. For some others, several problems were encountered related to hardware technical failures and to bad weather conditions. The paper will present the experiment programme conducted at the Mars Flashline Research Station, the problems encountered and the lessons learned from an EVA operational point of view. Suggestions to improve foreseen Martian EVA operations will be discussed.

Education in the field of photonics is usually somehow complex due to the fact that most of the programs include just a few subjects on the field, apart from specific Master programs in Photonics. There are also specific doctorate programs dealing with photonics. Apart from the problems shared with photonics in education in general, biophotonics specifically needs an interdisciplinary approach between biomedical and technical or scientific fields. In this work, we present our education experience in teaching the subject Fundamentals of Biophotonics, intended preferentially to engineering Bachelor and Master degrees students, but also to science and medicine students. First it was necessary to join a teaching group coming from the scientific technical and medical fields, working together in the subject. This task was easier as our research group, the Applied Optical Techniques group, had previous contacts and experience in working with medicine professors and medical doctors at hospitals. The orientation of the subject, intended for both technical and medical students, has to be carefully selected. All this information could be employed by other education institutions willing to implement studies on biomedical optics.

Automatic sentence extraction for the detection of scientific paper relations
NASA Astrophysics Data System (ADS)
Sibaroni, Y.; Prasetiyowati, S. S.; Miftachudin, M.
2018-03-01
The relations between scientific papers are very useful for researchers to see the interconnection between scientific papers quickly. By observing the inter-article relationships, researchers can identify, among others, the weaknesses of existing research, performance improvements achieved to date, and tools or data typically used in research in specific fields. So far, methods that have been developed to detect paper relations include machine learning and rule-based methods. However, a problem still arises in the process of sentence extraction from scientific paper documents, which is still done manually. This manual process causes the detection of scientific paper relations longer and inefficient. To overcome this problem, this study performs an automatic sentences extraction while the paper relations are identified based on the citation sentence. The performance of the built system is then compared with that of the manual extraction system. The analysis results suggested that the automatic sentence extraction indicates a very high level of performance in the detection of paper relations, which is close to that of manual sentence extraction.

several studies have examined the academic production of the researchers at the CNPq, in several areas of knowledge. The aim of this study was to evaluate the scientific production of researchers in Hematology/Oncology who hold scientific productivity grants from the Brazilian Council for Scientific and Technological Development. the Academic CVs of 28 researchers in Hematology/Oncology with active grants in the three-year period from 2006 to 2008 were included in the analysis. The variables of interest were: institution, researchers' time after doctorate, tutoring of undergraduate students, masters and PhD degree, scientific production and its impact. from a total of 411 researchers in Medicine, 28 (7%) were identified as being in the area of Hematology/Oncology. There was a slight predominance of males (53.6%) and grant holders in category 1. Three Brazilian states are responsible for approximately 90% of the researchers: São Paulo (21,75%), Rio de Janeiro (3,11%), and Minas Gerais (2, 7%). During their academic careers, the researchers published 2,655 articles, with a median of 87 articles per researcher (IQR = 52 to 122). 65 and 78% of this total were indexed on the Web of Science and Scopus databases, respectively. The researchers received 14,247 citations on the WoS database with a median of 385 citations per researcher. The average number of citations per article was 8.2. in this investigation, it was noted that researchers in the field of Hematology/Oncology have a relevant scientific output from the point of view of quantity and quality compared to other medical specialties.

In recent years emphasis has been placed on evaluation studies and the publication of scientific papers in national and international journals. In this regard the publication of scientific papers in journals in the Institute for Scientific Information (ISI) database is highly recommended. The evaluation of scientific output via articles in journals indexed in the ISI database will enable the Iranian research authorities to allocate and organize research budgets and human resources in a way that maximises efficient science production. The purpose of the present paper is to publish a general and valid view of science production in the field of stem cells. In this research, outputs in the field of stem cell research are evaluated by survey research, the method of science assessment called Scientometrics in this branch of science. A total of 1528 documents was extracted from the ISI database and analysed using descriptive statistics software in Excel. The results of this research showed that 1528 papers in the stem cell field in the Web of Knowledge database were produced by Iranian researchers. The top ten Iranian researchers in this field have produced 936 of these papers, equivalent to 61.3% of the total. Among the top ten, Soleimani M. has occupied the first place with 181 papers. Regarding international scientific participation, Iranian researchers have cooperated to publish papers with researchers from 50 countries. Nearly 32% (452 papers) of the total research output in this field has been published in the top 10 journals. These results show that a small number of researchers have published the majority of papers in the stem cell field. International participation in this field of research unacceptably low. Such participation provides the opportunity to import modern science and international experience into Iran. This not only causes scientific growth, but also improves the research and enhances opportunities for employment and professional development. Iranian scientific outputs from stem cell research should not be limited to only a few specific journals.

Research experiences for science teachers are an important mechanism for increasing classroom teachers' science content knowledge and facility with "real world" research processes. We have developed and implemented a summer scientific research and education workshop model for high school teachers and students which promotes classroom science inquiry projects and produces important research results supporting our overarching scientific agenda. The summer training includes development of a scientific research framework, design and implementation of preliminary studies, extensive field research and training in and access to instruments, measurement techniques and statistical tools. The development and writing of scientific papers is used to reinforce the scientific research process. Using these skills, participants collaborate with scientists to produce research quality data and analysis. Following the summer experience, teachers report increased incorporation of research inquiry in their classrooms and student participation in science fair projects. This workshop format was developed for an NSF Biocomplexity Research program focused on the interaction of urban climates, air quality and human response and can be easily adapted for other scientific research projects.

When scientists become Nobel laureates, they become famous in science and public life, but few studies have examined the nature of their scientific celebrity. This article examines how Scientific American portrayed laureates in order to identify and explain core features of Nobel fame. It examines the portrayals of seven laureates - Francis Crick, Linus Pauling, Hans Bethe, Murray Gell-Mann, Brian Josephson, Philip Anderson and Subrahmanyan Chandrasekhar - in magazine profiles written between 1992 and 1995 by science writer John Horgan. Its textual analysis finds the scientists are portrayed as combining the sociological characteristics of genius, including enormous productivity and lasting impact, with the representational characteristics of celebrities, such as the merging of public and private lives. Their form of scientific celebrity is grounded in their field-changing research, which is presented as a product of their idiosyncratic personalities. Nobel science is presented as knowledge created by an ultra-elite of exceptional individuals.

Exascale computing systems are essential for the scientific fields that will transform the 21st century global economy, including energy, biotechnology, nanotechnology, and materials science. Progress in these fields is predicated on the ability to perform advanced scientific and engineering simulations, and analyze the deluge of data. On July 29, 2013, ASCAC was charged by Patricia Dehmer, the Acting Director of the Office of Science, to assemble a subcommittee to provide advice on exascale computing. This subcommittee was directed to return a list of no more than ten technical approaches (hardware and software) that will enable the development of a systemmore » that achieves the Department's goals for exascale computing. Numerous reports over the past few years have documented the technical challenges and the non¬-viability of simply scaling existing computer designs to reach exascale. The technical challenges revolve around energy consumption, memory performance, resilience, extreme concurrency, and big data. Drawing from these reports and more recent experience, this ASCAC subcommittee has identified the top ten computing technology advancements that are critical to making a capable, economically viable, exascale system.« less
Extraterrestrial Virtual Field Experience: Water at Meridiani

The Spacecraft Planetary Imaging Facility (SPIF) at Cornell University, in collaboration with Million Concepts and the Paleontological Research Institute (PRI), has developed the Extraterrestrial Virtual Field Experience (EVFE), a web-based, game-like and inquiry-driven classroom activity targeted to middle school through undergraduate introductory Earth science classrooms. Students play the role of mission scientists for a NASA rover mission, tasked with targeting the rover's scientific instruments to investigate a specific scientific question about the landing site. As with the real mission, the student operators must optimize the efficient use of limited resources and time against the need to make observations to address working hypotheses. The activity uses only real--not artificial or simulated--mission data, and students are guided throughout by a "Mission Manager" who provides hints and advice about the scientific meaning of observations within the broader context of the mission objectives. The MER Opportunity EVFE is a pilot effort, the first of five EVFE modules planned a rate of one per year that will feature different NASA missions and scientific topics. The MER Opportunity EVFE has already been developed and focuses on the investigation of the history of water on Mars at the Meridiani landing site of the Opportunity rover. The module includes a teacher guide and is currently available to educators through the SPIF website.

The Biologic Analog Science Associated with Lava Terrains (BASALT) project is a four-year program dedicated to iteratively designing, implementing, and evaluating concepts of operations (ConOps) and supporting capabilities to enable and enhance scientific exploration for future human Mars missions. The BASALT project has incorporated three field deployments during which real (non-simulated) biological and geochemical field science have been conducted at two high-fidelity Mars analog locations under simulated Mars mission conditions, including communication delays and data transmission limitations. BASALT's primary Science objective has been to extract basaltic samples for the purpose of investigating how microbial communities and habitability correlate with the physical and geochemical characteristics of chemically altered basalt environments. Field sites include the active East Rift Zone on the Big Island of Hawai'i, reminiscent of early Mars when basaltic volcanism and interaction with water were widespread, and the dormant eastern Snake River Plain in Idaho, similar to present-day Mars where basaltic volcanism is rare and most evidence for volcano-driven hydrothermal activity is relict. BASALT's primary Science Operations objective has been to investigate exploration ConOps and capabilities that facilitate scientific return during human-robotic exploration under Mars mission constraints. Each field deployment has consisted of ten extravehicular activities (EVAs) on the volcanic flows in which crews of two extravehicular and two intravehicular crewmembers conducted the field science while communicating across time delay and under bandwidth constraints with an Earth-based Mission Support Center (MSC) comprised of expert scientists and operators. Communication latencies of 5 and 15 min one-way light time and low (0.512 Mb/s uplink, 1.54 Mb/s downlink) and high (5.0 Mb/s uplink, 10.0 Mb/s downlink) bandwidth conditions were evaluated. EVA crewmembers communicated with the MSC via voice and text messaging. They also provided scientific instrument data, still imagery, video streams from chest-mounted cameras, GPS location tracking information. The MSC monitored and reviewed incoming data from the field across delay and provided recommendations for pre-sampling and sampling tasks based on their collective expertise. The scientists used dynamic priority ranking lists, referred to as dynamic leaderboards, to track and rank candidate samples relative to one another and against the science objectives for the current EVA and the overall mission. Updates to the dynamic leaderboards throughout the EVA were relayed regularly to the IV crewmembers. The use of these leaderboards enabled the crew to track the dynamic nature of the MSC recommendations and helped minimize crew idle time (defined as time spent waiting for input from Earth during which no other productive tasks are being performed). EVA timelines were strategically designed to enable continuous (delayed) feedback from an Earth-based Science Team while simultaneously minimizing crew idle time. Such timelines are operationally advantageous, reducing transport costs by eliminating the need for crews to return to the same locations on multiple EVAs while still providing opportunities for recommendations from science experts on Earth, and scientifically advantageous by minimizing the potential for cross-contamination across sites. This paper will highlight the space-to-ground interaction results from the three BASALT field deployments, including planned versus actual EVA timeline data, ground assimilation times (defined as the amount of time available to the MSC to provide input to the crew), and idle time. Furthermore, we describe how these results vary under the different communication latency and bandwidth conditions. Together, these data will provide a basis for guiding and prioritizing capability development for future human exploration missions.

A mathematical model was developed of the three-dimensional dynamics of a high-altitude scientific research balloon system perturbed from its equilibrium configuration by an arbitrary gust loading. The platform is modelled as a system of four coupled pendula, and the equations of motion were developed in the Lagrangian formalism assuming a small-angle approximation. Three-dimensional pendulation, torsion, and precessional motion due to Coriolis forces are considered. Aerodynamic and viscous damping effects on the pendulatory and torsional motions are included. A general model of the gust field incident upon the balloon system was developed. The digital computer simulation program is described, and a guide to its use is given.

To be competitive in 21st century science and exploration careers, graduate students in planetary science and related disciplines need mentorship and need to develop skills not always available at their home university, including fieldwork, mission planning, and communicating with others in the scientific and engineering communities in the U.S. and internationally. Programs offered by the Lunar and Planetary Institute (LPI) address these needs through summer internships and field training programs. From 2008-2012, LPI hosted the Lunar Exploration Summer Intern Program. This special summer intern program evaluated possible landing sites for robotic and human exploration missions to the lunar surface. By the end of the 2012 program, a series of scientifically-rich landing sites emerged, some of which had never been considered before. Beginning in 2015 and building on the success of the lunar exploration program, a new Exploration Science Summer Intern Program is being implemented with a broader scope that includes both the Moon and near-Earth asteroids. Like its predecessor, the Exploration Science Summer Intern Program offers graduate students a unique opportunity to integrate scientific input with exploration activities in a way that mission architects and spacecraft engineers can use. The program's activities may involve assessments and traverse plans for a particular destination or a more general assessment of a class of possible exploration targets. Details of the results of these programs will be discussed. Since 2010 graduate students have participated in field training and research programs at Barringer (Meteor) Crater and the Sudbury Impact Structure. Skills developed during these programs prepare students for their own thesis studies in impact-cratered terrains, whether they are on the Earth, the Moon, Mars, or other solar system planetary surface. Future field excursions will take place at these sites as well as the Zuni-Bandera Volcanic Field. Skills developed during the Zuni-Bandera training will prepare students for their own thesis studies of volcanic provinces on any solar system planetary surface where basaltic volcanism has occurred. Further details of these field trainings will also be discussed.

The number of publications in the scientific literature coming from an institution is an indicator of its scientific production. The scientific production of the hospitals of the Government of the City of Buenos Aires (GCBA) has been evaluated previously, but without discriminating how much of that production corresponded to other academic institutions settled there (University of Buenos Aires, UBA, National Council of Scientific Research and Techniques, CONICET). Our objective was to evaluate the publications included in PubMed that correspond to hospitals of the GCBA, describe their main characteristics, and discriminate the contribution of other academic institutions (UBA and CONICET). It is a cross-sectional study based on a PubMed search, using the name of each of the 34 GCBA hospitals, CONICET and UBA in the "affiliation" field. In total, 2727 publications from GCBA hospitals were identified (4.6% of Argentine publications); 73.9% in English, 78.9% in relation to humans, 37.2% in the last 5 years; 6.4% with high level of evidence (clinical trials and meta-analysis), and 28.4% including children. Compared to the national total, the GCBA publications include fewer works in English, more research in humans, more clinical trials and more research in children. Of the publications corresponding to hospitals of the GCBA, 90.4% did not share the affiliation with CONICET or with UBA. In conclusion, the GCBA hospitals generated 4.6% of the total Argentine publications in PubMed; and 90% of these was not shared with UBA or CONICET. Publications from GCBA institutions include more clinical trials and research in children.

Fernbank Science Center in Atlanta, GA (USA) offers instruction in planetary science and astronomy to gifted 9th grade students within a program called "Scientific Tools and Techniques" (STT). Although STT provides a semester long overview of all sciences, the planetary science / astronomy section is innovative since students have access to instruction in the Center's Zeiss planetarium and observatory, which includes a 0.9 m cassegrain telescope. The curriculum includes charting the positions of planets in planetarium the sky; telescopic observations of the Moon and planets; hands-on access to meteorites and tektites; and an introduction to planetary spectroscopy utilizing LPI furnished ALTA reflectance spectrometers. In addition, students have the opportunity to watch several full dome planetary themed planetarium presentations, including "Back to the Moon for Good" and "Ring World: Cassini at Saturn." An overview of NASA's planetary exploration efforts is also considered, with special emphasis on the new Orion / Space Launch System for human exploration of the solar system. A primary goal of our STT program is to not only engage but encourage students to pursue careers in the field of science, with the hope of inspiring future scientists / leaders in the field of planetary science.
A standard telemental health evaluation model: the time is now.
Kramer, Greg M; Shore, Jay H; Mishkind, Matt C; Friedl, Karl E; Poropatich, Ronald K; Gahm, Gregory A
2012-05-01
The telehealth field has advanced historic promises to improve access, cost, and quality of care. However, the extent to which it is delivering on its promises is unclear as the scientific evidence needed to justify success is still emerging. Many have identified the need to advance the scientific knowledge base to better quantify success. One method for advancing that knowledge base is a standard telemental health evaluation model. Telemental health is defined here as the provision of mental health services using live, interactive video-teleconferencing technology. Evaluation in the telemental health field largely consists of descriptive and small pilot studies, is often defined by the individual goals of the specific programs, and is typically focused on only one outcome. The field should adopt new evaluation methods that consider the co-adaptive interaction between users (patients and providers), healthcare costs and savings, and the rapid evolution in communication technologies. Acceptance of a standard evaluation model will improve perceptions of telemental health as an established field, promote development of a sounder empirical base, promote interagency collaboration, and provide a framework for more multidisciplinary research that integrates measuring the impact of the technology and the overall healthcare aspect. We suggest that consideration of a standard model is timely given where telemental health is at in terms of its stage of scientific progress. We will broadly recommend some elements of what such a standard evaluation model might include for telemental health and suggest a way forward for adopting such a model.

Field expeditions that simulate the operations of robotic planetary exploration missions at analog sites on Earth can help establish best practices and are therefore a positive contribution to the planetary exploration community. There are many sites in Iceland that possess heritage as planetary exploration analog locations and whose environmental extremes make them suitable for simulating scientific sampling and robotic operations. We conducted a planetary exploration analog mission at two recent lava fields in Iceland, Fimmvörðuháls (2010) and Eldfell (1973), using a specially developed field laboratory. We tested the utility of in-field site sampling down selection and tiered analysis operational capabilities with three life detection and characterization techniques: fluorescence microscopy (FM), adenine-triphosphate (ATP) bioluminescence assay, and quantitative polymerase chain reaction (qPCR) assay. The study made use of multiple cycles of sample collection at multiple distance scales and field laboratory analysis using the synchronous life-detection techniques to heuristically develop the continuing sampling and analysis strategy during the expedition. Here we report the operational lessons learned and provide brief summaries of scientific data. The full scientific data report will follow separately. We found that rapid in-field analysis to determine subsequent sampling decisions is operationally feasible, and that the chosen life detection and characterization techniques are suitable for a terrestrial life-detection field mission. In-field analysis enables the rapid obtainment of scientific data and thus facilitates the collection of the most scientifically relevant samples within a single field expedition, without the need for sample relocation to external laboratories. The operational lessons learned in this study could be applied to future terrestrial field expeditions employing other analytical techniques and to future robotic planetary exploration missions.
Negotiating boundaries: Encyclopédie, romanticism, and the construction of science.
Fetz, Marcelo
2017-01-01
Natural history in the eighteenth and nineteenth centuries has been widely debated in the field of the social sciences. This paper explores the social negotiation of boundaries in the Encyclopédie and romantic science. Highlighting the importance of imagination and aesthetics to the scientific realms, we perceive a different comprehension of the scientific field through the empirical study of how scientific demarcation is constructed. Works by Erasmus Darwin, Goethe, and Humboldt illustrate how reliable science was performed through atypical scientific methods. After pointing out the links between literary, artistic, and scientific works, we then debate a series of changes that framed the scientific imagery of romantic and encyclopaedic sciences.

Towards writing the encyclopaedia of life: an introduction to DNA barcoding
Savolainen, Vincent; Cowan, Robyn S; Vogler, Alfried P; Roderick, George K; Lane, Richard
2005-01-01
An international consortium of major natural history museums, herbaria and other organizations has launched an ambitious project, the ‘Barcode of Life Initiative’, to promote a process enabling the rapid and inexpensive identification of the estimated 10 million species on Earth. DNA barcoding is a diagnostic technique in which short DNA sequence(s) can be used for species identification. The first international scientific conference on Barcoding of Life was held at the Natural History Museum in London in February 2005, and here we review the scientific challenges discussed during this conference and in previous publications. Although still controversial, the scientific benefits of DNA barcoding include: (i) enabling species identification, including any life stage or fragment, (ii) facilitating species discoveries based on cluster analyses of gene sequences (e.g. cox1=CO1, in animals), (iii) promoting development of handheld DNA sequencing technology that can be applied in the field for biodiversity inventories and (iv) providing insight into the diversity of life.

Medical Subspecialty Textbooks in the 21st Century. Essential or Headed for Extinction?
Broaddus, V Courtney; Grippi, Michael A
2015-08-01
In recent years, the role of medical subspecialty textbooks as sources of information for students, trainees, and practicing clinicians has been challenged. Although the structure of textbooks continues to evolve from standard, printed versions to digital formats, including e-books and online texts, we maintain that the authoritative compilation of clinical and scientific material by experts in the field (i.e., a modern-day textbook) remains central to the education, training, and practice of subspecialists. Regardless of format, an effective medical subspecialty textbook is authoritative, comprehensive, and integrated in its coverage of the subject. Textbook content represents a unique synthesis of clinical and scientific material of real educational and clinical value. Incorporation of illustrations, including figures, tables, videos, and audios, bolsters the presentation and further solidifies the reader's understanding of the subject. The textbook, both printed and digital, reinforces the many widely available online resources and serves as a platform from which to evaluate other sources of information and to launch additional scientific and clinical inquiry.

Previous papers dealt with the concept of psyche as that dynamic field which underlies the subjective experience of mind. A new paradigm, psychodynamic science, was suggested for dealing with subjective data. The venue of the psychotherapeutic consulting room is now brought directly into science, expanding the definition of psychotherapy to include both humanistic and scientific elements. Certain concepts were introduced to amplify this new scientific model, including psyche as hypothetical construct, the concept of meaning as replacement for operational validation in scientific investigation, the synonymity of meaning and insight, and the concept of synchronicity, together with the meaning-connected affect of numinosity. The presence of unhealthy anxiety as the conservative ego attempts to preserve its integrity requires a deeper look at the concept of meaning. This leads to a distinction between meaning and erroneous meaning. The main body of this paper amplifies that distinction, and introduces the concept of intolerance of ambiguity in the understanding of erroneous meanings and their connection with human neurosis.

The depth of fields: Managing focus in the epistemic subcultures of mind and brain science.
Peterson, David
2017-02-01
The 'psy' sciences emerged from the tangled roots of philosophy, physiology, biology and medicine, and these origins have produced heterogeneous fields. Scientists in these areas work in a complex, overlapping ecology of fields that results in the constant co-presence of dissonant theories, methods and research objects. This raises questions regarding how conceptual clarity is maintained. Using the optical metaphor 'depth of field', I show how researchers in all fields marginalize potential threats to routine scientific work by framing them as either too broad and imprecise or too narrow and technical. The appearance of this defocusing and devaluing across sites suggests a general aspect of scientific cognition, rather than a by-product of any specific scientific dispute.

Ecological research and conservation practice frequently raise difficult and varied ethical questions for scientific investigators and managers, including duties to public welfare, nonhuman individuals (i.e., animals and plants), populations, and ecosystems. The field of environmental ethics has contributed much to the understanding of general duties and values to nature, but it has not developed the resources to address the diverse and often unique practical concerns of ecological researchers and managers in the field, lab, and conservation facility. The emerging field of "ecological ethics" is a practical or scientific ethics that offers a superior approach to the ethical dilemmas of the ecologist and conservation manager. Even though ecological ethics necessarily draws from the principles and commitments of mainstream environmental ethics, it is normatively pluralistic, including as well the frameworks of animal, research, and professional ethics. It is also methodologically pragmatic, focused on the practical problems of researchers and managers and informed by these problems in turn. The ecological ethics model offers environmental scientists and practitioners a useful analytical tool for identifying, clarifying, and harmonizing values and positions in challenging ecological research and management situations. Just as bioethics provides a critical intellectual and problem-solving service to the biomedical community, ecological ethics can help inform and improve ethical decision making in the ecology and conservation communities.

Commercial applications of data mining in areas such as e-commerce, market-basket analysis, text-mining, and web-mining have taken on a central focus in the JCDD community. However, there is a significant amount of innovative data mining work taking place in the context of scientific and engineering applications that is not well represented in the mainstream KDD conferences. For example, scientific data mining techniques are being developed and applied to diverse fields such as remote sensing, physics, chemistry, biology, astronomy, structural mechanics, computational fluid dynamics etc. In these areas, data mining frequently complements and enhances existing analysis methods based on statistics, exploratorymore » data analysis, and domain-specific approaches. On the surface, it may appear that data from one scientific field, say genomics, is very different from another field, such as physics. However, despite their diversity, there is much that is common across the mining of scientific and engineering data. For example, techniques used to identify objects in images are very similar, regardless of whether the images came from a remote sensing application, a physics experiment, an astronomy observation, or a medical study. Further, with data mining being applied to new types of data, such as mesh data from scientific simulations, there is the opportunity to apply and extend data mining to new scientific domains. This one-day workshop brings together data miners analyzing science data and scientists from diverse fields to share their experiences, learn how techniques developed in one field can be applied in another, and better understand some of the newer techniques being developed in the KDD community. This is the fourth workshop on the topic of Mining Scientific Data sets; for information on earlier workshops, see http://www.ahpcrc.org/conferences/. This workshop continues the tradition of addressing challenging problems in a field where the diversity of applications is matched only by the opportunities that await a practitioner.« less
History and conceptual developments in vascular biology and angiogenesis research: a personal view.
Bikfalvi, Andreas
2017-11-01
Vascular biology is an important scientific domain that has gradually penetrated many medical and scientific fields. Scientists are most often focused on present problems in their daily scientific work and lack awareness regarding the evolution of their domain throughout history and of how philosophical issues are related to their research field. In this article, I provide a personal view with an attempt to conceptualize vascular development research that articulates lessons taken from history, philosophy, biology and medicine. I discuss selected aspects related to the history and the philosophy of sciences that can be extracted from the study of vascular development and how conceptual progress in this research field has been made. I will analyze paradigm shifts, cross-fertilization of different fields, technological advances and its impact on angiogenesis and discuss issues related to evolutionary biology, proximity of different molecular systems and scientific methodologies. Finally, I discuss briefly my views where the field is heading in the future.

Dietary isoflavones and gastric cancer: A brief review of current studies.
Golpour, Sahar; Rafie, Nahid; Safavi, Seyyed Morteza; Miraghajani, Maryam
2015-09-01
Although several in vitro and animal studies have suggested that isoflavones might exert inhibitory effects on gastric carcinogenesis, epidemiologic studies have reported inconclusive results in this field. The aim of this brief review was to investigate whether such an association exists among dietary isoflavones and gastric cancer incidence, prevention, and mortality in epidemiologic studies. We conducted a search of PubMed, Google Scholar, Cochrane, Science direct, and Iranian Scientific Databases including Scientific Information Database and IranMedex Database (up to November 2014) using common keywords for studies that focused on dietary isoflavones and gastric cancer risk. A total of nine epidemiologic studies consisting of five case-controls, three prospective cohorts, and one ecologic study were included in this review. An inverse association between dietary isoflavones and gastric cancer was shown in only one case-control and one ecologic study. In summary, whether anticarcinogenic properties of isoflavones are established, research found no substantial correlation in this field. There are insufficient studies to draw any firm conclusions about the relationship between isoflavones intake and the risk of gastric cancer. Hence, further evidence from cohort and trial studies are needed.
The Future of Endothelin Research: Scientific Mentoring and Beyond
Barton, Matthias; Pollock, David M.
2013-01-01
Endothelium-dependent regulation of vascular tone was one of the key discoveries in physiology in the 1980s, including the characterization of endothelium-derived vasoactive factors such as endothelin. Young investigators, often while starting research as part of their PhD degree, have been instrumental in carrying out the work that led some of the most important discoveries in the endothelin field. This article reviews the importance of mentoring for research in general and for endothelin research in particular, including examples of outstanding young investigators that have been instrumental in some of the key discoveries in the endothelin field. Recognizing scientific excellence among young investigators has a long tradition in the history of the International Conferences on Endothelin. Winners of “Young Investigator Awards” of the past five endothelin conferences (ET-8, ET-9, ET-10, ET-11, and ET-12) are presented, as well as recipients of the “ET-12 Best Presentation Awards” established on the occasion of the Twelfth International Conference on Endothelin ET-12 in Cambridge in September 2011.

The scientific objectives of the Ulysses Unified Radio and Plasma wave (URAP) experiment are twofold: (1) the determination of the direction, angular size, and polarization of radio sources for remote sensing of the heliosphere and the Jovian magnetosphere and (2) the detailed study of local wave phenomena, which determine the transport coefficients of the ambient plasma. A brief discussion of the scientific goals of the experiment is followed by a comprehensive description of the instrument. The URAP sensors consist of a 72.5 m electric field antenna in the spin plane, a 7.5-m electric field monopole along the spin axis of a pair of orthogonal search coil magnetic antennas. The various receivers, designed to encompass specific needs of the investigation, cover the frequency range from dc to 1 MHz. A relaxation sounder provides very accurate electron density measurements. Radio and plasma wave observations are shown to demonstrate the capabilities and limitations of the URAP instruments: radio observations include solar bursts, auroral kilometric radiation, and Jovian bursts; plasma waves include Langmuir waves, ion acousticlike noise, and whistlers.

Analogs are destinations on Earth that allow researchers to approximate operational and/or physical conditions on other planetary bodies and within deep space. Over the past decade, our team has been conducting geobiological field science studies under simulated deep space and Mars mission conditions. Each of these missions integrate scientific and operational research with the goal to identify concepts of operations (ConOps) and capabilities that will enable and enhance scientific return during human and human-robotic missions to the Moon, into deep space and on Mars. Working under these simulated mission conditions presents a number of unique challenges that are not encountered during typical scientific field expeditions. However, there are significant benefits to this working model from the perspective of the human space flight and scientific operations research community. Specifically, by applying human (and human-robotic) mission architectures to real field science endeavors, we create a unique operational litmus test for those ConOps and capabilities that have otherwise been vetted under circumstances that did not necessarily demand scientific data return meeting the rigors of peer-review standards. The presentation will give an overview of our team's recent analog research, with a focus on the scientific operations research. The intent is to encourage collaborative dialog with a broader set of analog research community members with an eye towards future scientific field endeavors that will have a significant impact on how we design human and human-robotic missions to the Moon, into deep space and to Mars.
"Balkan journal of medical genetics"--facts, editorial policies, practices and challenges.
Plaseska Karanfilska, Dijana; Sukarova Stefanovska, Emilija
2014-01-01
The Balkan Journal of Medical Genetics (BJMG) is an international, open access journal that publishes scientific papers covering different aspects of medical genetics. It is published by the Macedonian Academy of Sciences and Arts twice a year in both printed and electronic versions. BJMG is covered by many abstracting and indexing databases, including PubMed Central and Thomson Reuters. Although there are many journals in the field of medical genetics, only a few come from regions outside Western Europe and North America. Being one of these few journals, BJMG aims to promote genetics and research on this topic in the Balkan countries and beyond. BJMG's ultimate goal is to raise the scientific quality and metrics of the journal and provide a better place for BJMG in the community of scientific journals.
A DBMS architecture for global change research

1993-08-01
The goal of this research is the design and development of an integrated system for the management of very large scientific databases, cartographic/geographic information processing, and exploratory scientific data analysis for global change research. The system will represent both spatial and temporal knowledge about natural and man-made entities on the eath's surface, following an object-oriented paradigm. A user will be able to derive, modify, and apply, procedures to perform operations on the data, including comparison, derivation, prediction, validation, and visualization. This work represents an effort to extend the database technology with an intrinsic class of operators, which is extensible and responds to the growing needs of scientific research. Of significance is the integration of many diverse forms of data into the database, including cartography, geography, hydrography, hypsography, images, and urban planning data. Equally important is the maintenance of metadata, that is, data about the data, such as coordinate transformation parameters, map scales, and audit trails of previous processing operations. This project will impact the fields of geographical information systems and global change research as well as the database community. It will provide an integrated database management testbed for scientific research, and a testbed for the development of analysis tools to understand and predict global change.

Phylomemetic patterns in science evolution--the rise and fall of scientific fields.
Chavalarias, David; Cointet, Jean-Philippe
2013-01-01
We introduce an automated method for the bottom-up reconstruction of the cognitive evolution of science, based on big-data issued from digital libraries, and modeled as lineage relationships between scientific fields. We refer to these dynamic structures as phylomemetic networks or phylomemies, by analogy with biological evolution; and we show that they exhibit strong regularities, with clearly identifiable phylomemetic patterns. Some structural properties of the scientific fields - in particular their density -, which are defined independently of the phylomemy reconstruction, are clearly correlated with their status and their fate in the phylomemy (like their age or their short term survival). Within the framework of a quantitative epistemology, this approach raises the question of predictibility for science evolution, and sketches a prototypical life cycle of the scientific fields: an increase of their cohesion after their emergence, the renewal of their conceptual background through branching or merging events, before decaying when their density is getting too low.

3) significant changes that have occurred in Antarctic exploration and research since World War II will be discussed at the end of this report. Subsequent Open-File Reports will provide a year-by-year documentation of USGS scientific activities and accomplishments in Antarctica beginning with the post-IGY, 1959-60 research team. One Open-File Report is planned to be written for each field-based season. For an example of the series format, see Open-File Reports 2006-1113 (Meunier, 2007a) and 2006-1114 (Meunier, 2007b). This report is a companion document to Open-File Report 2006-1116 (Meunier, 2007c). The USGS mapping and science programs in Antarctica are among the longest continuously funded projects in the United States Antarctic Program (USAP). The 2005-06 field season is the 56th consecutive U.S. expedition in which USGS scientists have been participants, starting in 1946. USGS and the National Science Foundation (NSF) cooperation began with the establishment by NSF of the U.S. Antarctic (Research) Program [USA(R)P] in 1958-59 under Operation Deep Freeze IV (DF IV) and was given the responsibility for the principal coordination and management of all U.S. scientific activities in Antarctica in Deep Freeze 60 (DF 60) (1959-60). Financial support from NSF, mostly in the form of Memorandum of Understandings (MOUs) and Cooperative Agreements, extends back to this period and can be attributed to the need for accurate geologic, geophysical, and topographic base maps of specific field areas or regions where NSF-funded science projects were planned. The epoch of Antarctic exploration during the IGY was driven by science and, in a spirit of peaceful cooperation, the international scientific community wanted to limit military activities on the continent to logistical support (Meunier, 1979 [2007], p. 38). The USGS, a Federal civilian science agency in the Department of the Interior, has, since its founding in 1879, carried out numerous field-based national (and some international) programs in biology, geology, geophysics, hydrology, and mapping. Therefore, the USGS was the obvious choice for these tasks, because it already had a professional staff of experienced mapmakers, scientists, and program managers with the foresight, dedication, and understanding of the need for accurate maps to support the science programs in Antarctica when asked to do so by the U.S. National Academy of Sciences. Public Laws 85-743 and 87-626, signed in August 1958, and in September 1962, respectively, authorized the Secretary, U.S. Department of the Interior, through the USGS, to support mapping and scientific work in Antarctica (Meunier, 1979 [2007], appendix A). Open-File Report 2006-1116 includes scanned facsimiles of postal cachets. It has become an international practice to create postal cachets to commemorate special events and projects in Antarctica. A cachet is defined as a seal or commemorative design printed or stamped on an envelope to mark a philatelic or special event. The inked impression illustrates to the scientist, historian, stamp collector, and general public the multidisciplinary science projects staffed by USGS and collaborating scientists during the field season. Since 1960, philatelic cachets have been created by team members for each USGS field season and, in most cases, these cachets depict the specific geographic areas and field season program objectives. The cachets become a convenient documentation of the people, projects, and geographic places of interest for that year. Because the cachets are representative of USGS activities, each year's cachet is included as a digital facsimile in that year's Open-File Report. In the 1980s, multiple USGS cachets were prepared each year, one for use by the winter team at Amundsen-Scott South Pole Station and the other for the project work areas of the austral summer field season programs.

The nascent field of gravitational wave astronomy offers many opportunities for effective and inspirational astronomy outreach. Gravitational waves, the `ripples in spacetime' predicted by Einstein's general theory of relativity, are produced by some of the most energetic and dramatic phenomena in the cosmos, including black holes, neutron stars and supernovae - and their discovery should help to address a number of fundamental questions in physics, from the evolution of stars and galaxies to the origin of dark energy and the nature of spacetime itself. Moreover, the cutting-edge technology developed to search for gravitational waves is pushing back the frontiers of many fields, from lasers and materials science to high performance computing, and thus provides a powerful showcase for the attractions and challenges of a career in science and engineering. For several years a worldwide network of ground-based laser interferometric gravitational wave detectors, built and run by the LIGO Scientific Collaboration, has been fully operational. These detectors are already among the most sensitive scientific instruments on the planet but in the next few years their sensitivity will achieve further significant improvement. Those developments promise to open an exciting new window on the Universe, heralding the arrival of gravitational wave astronomy as a revolutionary, new observational field. In this poster we describe the extensive program of public outreach activities already undertaken by the LIGO Scientific Collaboration, and a number of special events which we are planning for IYA2009. These activities include: * programs at Science Centers and Observatory Visitor Centers * programs on gravitational wave astronomy for the classroom, across the K-12 spectrum * interdisciplinary events linking gravitational wave astronomy to music and the visual arts * research experiences for schools and citizens through the highly successful `Einstein@Home' program.

Health Resort Medicine, Balneology, Medical Hydrology and Climatology are not fully recognised as independent medical specialties at a global international level. Analysing the reasons, we can identify both external (from outside the field) and internal (from inside the field) factors. External arguments include, e.g. the lack of scientific evidence, the fact that Balneotherapy and Climatotherapy is not used in all countries, and the fact that Health Resort Medicine, Balneology, Medical Hydrology and Climatology focus only on single methods and do not have a comprehensive concept. Implicit barriers are the lack of international accepted terms in the field, the restriction of being allowed to practice the activities only in specific settings, and the trend to use Balneotherapy mainly for wellness concepts. Especially the implicit barriers should be subject to intense discussions among scientists and specialists. This paper suggests one option to tackle the problem of implicit barriers by making a proposal for a structure and description of the medical field, and to provide some commonly acceptable descriptions of content and terminology. The medical area can be defined as “medicine in health resorts” (or “health resort medicine”). Health resort medicine includes “all medical activities originated and derived in health resorts based on scientific evidence aiming at health promotion, prevention, therapy and rehabilitation”. Core elements of health resort interventions in health resorts are balneotherapy, hydrotherapy, and climatotherapy. Health resort medicine can be used for health promotion, prevention, treatment, and rehabilitation. The use of natural mineral waters, gases and peloids in many countries is called balneotherapy, but other (equivalent) terms exist. Substances used for balneotherapy are medical mineral waters, medical peloids, and natural gases (bathing, drinking, inhalation, etc.). The use of plain water (tap water) for therapy is called hydrotherapy, and the use of climatic factors for therapy is called climatotherapy. Reflecting the effects of health resort medicine, it is important to take other environmental factors into account. These can be classified within the framework of the ICF (International Classification of Functioning, Disability and Health). Examples include receiving health care by specialised doctors, being well educated (ICF-domain: e355), having an environment supporting social contacts (family, peer groups) (cf. ICF-domains: d740, d760), facilities for recreation, cultural activities, leisure and sports (cf. ICF-domain: d920), access to a health-promoting atmosphere and an environment close to nature (cf. ICF-domain: e210). The scientific field dealing with health resort medicine is called health resort sciences. It includes the medical sciences, psychology, social sciences, technical sciences, chemistry, physics, geography, jurisprudence, etc. Finally, this paper proposes a systematic international discussion of descriptions in the field of Health Resort Medicine, Balneology, Medical Hydrology and Climatology, and discusses short descriptive terms with the goal of achieving internationally accepted distinct terms. This task should be done via a structured consensus process and is of major importance for the publication of scientific results as well as for systematic reviews and meta-analyses.

Scientifically defensible predictions of field scale U(VI) transport in groundwater requires an understanding of key processes at multiple scales. These scales range from smaller than the sediment grain scale (less than 10 μm) to as large as the field scale which can extend over several kilometers. The key processes that need to be considered include both geochemical reactions in solution and at sediment surfaces as well as physical transport processes including advection, dispersion, and pore-scale diffusion. The research summarized in this report includes both experimental and modeling results in batch, column and tracer tests. The objectives of this research were to: (1) quantify the rates of U(VI) desorption from sediments acquired from a uranium contaminated aquifer in batch experiments;(2) quantify rates of U(VI) desorption in column experiments with variable chemical conditions, and(3) quantify nonreactive tracer and U(VI) transport in field tests.

Background : This paper is based on a panel discussion at the 32nd annual meeting of the International Society for Traumatic Stress Studies in Dallas, Texas, in November 2016. Objective : Paula Schnurr convened a panel of experts in the fields of public health and technology to address the topic: 'What I have changed my mind about and why.' Method : The panel included Richard Bryant, Lucy Berliner, Dean Kilpatrick, Albert ('Skip') Rizzo, and Josef Ruzek. Results : Panellists discussed innovative strategies for the dissemination of scientific knowledge and evidence-based treatment. Conclusions : Although there are effective treatments, there is a need to enhance the effectiveness of these treatments. There also is a need to develop simpler, low-cost strategies to disseminate effective treatments. However, technology approaches also offer pathways to increased dissemination. Researchers must communicate scientific findings more effectively to impact public opinion and public policy.

Current technologies have become a source of omnipresent electromagnetic pollution from generated electromagnetic fields and resulting electromagnetic radiation. In many cases this pollution is much stronger than any natural sources of electromagnetic fields or radiation. The harm caused by this pollution is still open to question since there is no clear and definitive evidence of its negative influence on humans. This is despite the fact that extremely low frequency electromagnetic fields were classified as potentially carcinogenic. For these reasons, in recent decades a significant growth can be observed in scientific research in order to understand the influence of electromagnetic radiation on living organisms. However, for this type of research the appropriate selection of relevant model organisms is of great importance. It should be noted here that the great majority of scientific research papers published in this field concerned various tests performed on mammals, practically neglecting lower organisms. In that context the objective of this paper is to systematise our knowledge in this area, in which the influence of electromagnetic radiation on lower organisms was investigated, including bacteria, E. coli and B. subtilis, nematode, Caenorhabditis elegans, land snail, Helix pomatia, common fruit fly, Drosophila melanogaster, and clawed frog, Xenopus laevis.

Managing scientific data is probably one the most challenging issue in modern science. The question is made even more sensitive with the need of preserving and managing high value fragile geological sam-ples: cores. Large international scientific programs, such as IODP or ICDP are leading an intense effort to solve this problem and propose detailed high standard work- and dataflows thorough core handling and curating. However most results derived from rather small-scale research programs in which data and sample management is generally managed only locally - when it is … The national excellence equipment program (Equipex) CLIMCOR aims at developing French facilities for coring and drilling investigations. It concerns indiscriminately ice, marine and continental samples. As part of this initiative, we initiated a reflexion about core curating and associated coring-data management. The aim of the project is to conserve all metadata from fieldwork in an integrated cyber-environment which will evolve toward laboratory-acquired data storage in a near future. In that aim, our demarche was conducted through an close relationship with field operators as well laboratory core curators in order to propose user-oriented solutions. The national core curating initiative currently proposes a single web portal in which all scientifics teams can store their field data. For legacy samples, this will requires the establishment of a dedicated core lists with associated metadata. For forthcoming samples, we propose a mobile application, under Android environment to capture technical and scientific metadata on the field. This application is linked with a unique coring tools library and is adapted to most coring devices (gravity, drilling, percussion, etc...) including multiple sections and holes coring operations. Those field data can be uploaded automatically to the national portal, but also referenced through international standards or persistent identifiers (IGSN, ORCID and INSPIRE) and displayed in international portals (currently, NOAA's IMLGS). In this paper, we present the architecture of the integrated system, future perspectives and the approach we adopted to reach our goals. We will also present in front of our poster, one of the three mobile applications, dedicated more particularly to the operations of continental drillings.
The Best and the Brightest in Geosciences: Broadening Representation in the Field

Geoscience research in government agencies and universities across the US is anchored by data collection from field and lab experiments. In these settings, the composition and the culture of the environment can be less welcoming for individuals from groups that are traditionally underrepresented in the geosciences. Ongoing efforts to address diversity and inclusion in the field and lab include top-down approaches that provide support and training for established geoscience leaders and bottom-up approaches that offer research internships and fellowships for students. To achieve success, effective strategies for broadening representation in the field must be developed and shared across the geosciences community to advance scientific innovation and create opportunities for success.

Scientific findings have revealed how much we have dramatically underestimated the intellectual, social and emotional capabilities of non-human animals, including their levels of self-consciousness and ability to suffer from psychological stress. In the 21st century, the field of animal ethics has evolved as a serious scientific discipline, and nowadays largely advocates that the way we treat animals, both legally and in practice, is morally wrong. Politics and legislation have reacted to these facts, to some extent, but neither current legislation nor current practice reflect the scientific and moral state-of-the-art. Too often, the will to change things is watered down in the decision-making process, e.g. in the drafting of legislation. In the field of animal experimentation there have been many genuine efforts by various players, to advance and apply the principles behind the Three Rs. However, the fundamental problem, i.e. the overall number of animals sacrificed for scientific purposes, has increased. Clearly, if we are serious about our will to regard animal experimentation as an ethical and societal problem, we have to put much more emphasis on addressing the question of how to avoid the use of animals in science. To achieve this goal, certain issues need to be considered: a) the present system of ethical evaluation of animal experiments, including testing for regulatory purposes, needs to be reformed and applied effectively to meet the legal and moral requirements; b) animal testing must be avoided in future legislation, and existing legislation has to be revised in that regard; c) resources from animal-based research have to re-allocated toward alternatives; and d) the academic curricula must be reformed to foster and integrate ethical and animal welfare issues. 2015 FRAME.

At about this time every year, I renew my memberships to several scientific societies, and every year I ask myself the same question: “Should I bother?” In years past, the answer was easy because being a member came with tangible benefits, such as inexpensive journals and the ability to submit abstracts to annual meetings. Nowadays, these perks don’t seem very important. Most society journals are freely available online, and the proliferation of scientific meetings has made it easier to find venues to present my current research. Thus, the volume with which I ask that question—“should I bother?”—has steadily increased. Mostmore » scientific societies were established to promote the development and acceptance of a particular field of research. Society journals and annual meetings were the primary way this was accomplished. More recently, the larger societies have expanded their roles to include lobbying for increases in research funding and providing career advice. Although these are worthwhile activities, I don’t need to belong to multiple scientific societies to support them. I almost always renew my society memberships, but I think that it is more out of a sense of tradition than need. Clearly, I am not the only scientist who is ambivalent about societies. Judging from their newsletters, many of the larger societies are struggling with stagnant or declining memberships, especially among young scientists. Although it is the youngest scientists who potentially have the most to gain from a scientific society (from networking, career advice), they are the ones who usually are most poorly served by those societies. This is because scientific societies generally cater to the status quo, not to the new and emerging elements of a field.« less

Scientists use the Earth as a tool for astrobiology by analyzing planetary field analogues (i.e. terrestrial samples and field sites that resemble planetary bodies in our Solar System). In addition, they expose the selected planetary field analogues in simulation chambers to conditions that mimic the ones of planets, moons and Low Earth Orbit (LEO) space conditions, as well as the chemistry occurring in interstellar and cometary ices. This paper reviews the ways the Earth is used by astrobiologists: (i) by conducting planetary field analogue studies to investigate extant life from extreme environments, its metabolisms, adaptation strategies and modern biosignatures; (ii) by conducting planetary field analogue studies to investigate extinct life from the oldest rocks on our planet and its biosignatures; (iii) by exposing terrestrial samples to simulated space or planetary environments and producing a sample analogue to investigate changes in minerals, biosignatures and microorganisms. The European Space Agency (ESA) created a topical team in 2011 to investigate recent activities using the Earth as a tool for astrobiology and to formulate recommendations and scientific needs to improve ground-based astrobiological research. Space is an important tool for astrobiology (see Horneck et al. in Astrobiology, 16:201-243, 2016; Cottin et al., 2017), but access to space is limited. Complementing research on Earth provides fast access, more replications and higher sample throughput. The major conclusions of the topical team and suggestions for the future include more scientifically qualified calls for field campaigns with planetary analogy, and a centralized point of contact at ESA or the EU for the organization of a survey of such expeditions. An improvement of the coordinated logistics, infrastructures and funding system supporting the combination of field work with planetary simulation investigations, as well as an optimization of the scientific return and data processing, data storage and data distribution is also needed. Finally, a coordinated EU or ESA education and outreach program would improve the participation of the public in the astrobiological activities.
Physics Literacy for All Students
NASA Astrophysics Data System (ADS)
Hobson, Art
2010-03-01
Physics teachers must broaden their focus from physics for scientists to physics for all. The reason, as the American Association for the Advancement of Science puts it, is: ``Without a scientifically literate population, the outlook for a better world is not promising.'' Physics for all (including the first course for scientists) should be conceptual, not technical. It should describe the universe as we understand it today, including special and general relativity, quantum physics, modern cosmology, the standard model, and quantum fields. Many science writers have shown this is possible. It should include physics-related social topics such as global warming and nuclear weapons, because citizens need to vote on these issues. Above all, it should emphasize the scientific process and the difference between science and nonsense. Science is based not on beliefs but rather on evidence and reason. We should constantly ask ``How do we know?'' and ``What is the evidence?''

Molecular pathological epidemiology (MPE) is a transdisciplinary and relatively new scientific discipline that integrates theory, methods, and resources from epidemiology, pathology, biostatistics, bioinformatics, and computational biology. The underlying objective of MPE research is to better understand the etiology and progression of complex and heterogeneous human diseases with the goal of informing prevention and treatment efforts in population health and clinical medicine. Although MPE research has been commonly applied to investigating breast, lung, and colorectal cancers, its methodology can be used to study most diseases. Recent successes in MPE studies include: (1) the development of new statistical methods to address etiologic heterogeneity; (2) the enhancement of causal inference; (3) the identification of previously unknown exposure-subtype disease associations; and (4) better understanding of the role of lifestyle/behavioral factors on modifying prognosis according to disease subtype. Central challenges to MPE include the relative lack of transdisciplinary experts, educational programs, and forums to discuss issues related to the advancement of the field. To address these challenges, highlight recent successes in the field, and identify new opportunities, a series of MPE meetings have been held at the Dana-Farber Cancer Institute in Boston, MA. Herein, we share the proceedings of the Third International MPE Meeting, held in May 2016 and attended by 150 scientists from 17 countries. Special topics included integration of MPE with immunology and health disparity research. This meeting series will continue to provide an impetus to foster further transdisciplinary integration of divergent scientific fields.

To help young scientists succeed in our field we should not only model scientific methods and inquiry, but also train them in the art of scientific writing - after all, poorly written proposals, reports or journal articles can be a show stopper for any researcher. Research internships are an effective place to provide such training, because they offer a unique opportunity to integrate writing with the process of conducting original research. This presentation will describe how scientific communication is integrated into the SOARS program. Significant Opportunities in Atmospheric Research and Science (SOARS) is an undergraduate-to graduate bridge program that broadens participation in the geosciences. SOARS aims to foster the next generation of leaders in the atmospheric and related sciences by helping students develop investigative expertise complemented by leadership and communication skills. Each summer, interns (called protégés) attend a weekly seminar designed to help them learn scientific writing and communication skills. The workshop is organized around the sections of a scientific paper. Workshop topics include reading and citing scientific literature, writing an introduction, preparing a compelling abstract, discussing results, designing effective figures, and writing illuminating conclusions. In addition, protégés develop the skills required to communicate their research to both scientists and non-scientists through the use of posters, presentations and informal 'elevator' speeches. Writing and communication mentors guide protégés in applying the ideas from the workshop to the protégés' required summer scientific paper, poster and presentation, while a strong peer-review component of the program gives the protégés a taste of analyzing, critiquing and collaborating within a scientific forum. This presentation will provide practical tips and lessons learned from over ten years of scientific communications workshops within the SOARS program, including workshop structure, curriculum development, textbooks, reading materials and online resources, peer review and specialty seminars.

Role of the observer in the scientific process in astrobiology and in defining life
NASA Astrophysics Data System (ADS)
Kolb, Vera M.
2010-09-01
The role of the observer in the scientific process has been studied in various contexts, including philosophical. It is notorious that the experiments are theory-loaded, that the observers pick and choose what they consider important based on their scientific and cultural backgrounds, and that the same phenomenon may be studied by different observers from different angles. In this paper we critically review various authors' views of the role of the observer in the scientific process, as they apply to astrobiology. Astrobiology is especially vulnerable to the role of the observer, since it is an interdisciplinary science. Thus, the backgrounds of the observers in the astrobiology field are even more heterogeneous than in the other sciences. The definition of life is also heavily influenced by the observer of life who injects his/her own prejudices in the process of observing and defining life. Such prejudices are often dictated by the state of science, instrumentation, and the science politics at the time, as well as the educational, scientific, cultural and other background of the observer.

Euclid and the Large Synoptic Survey Telescope (LSST) are poised to dramatically change the astronomy landscape early in the next decade. The combination of high-cadence, deep, wide-field optical photometry from LSST with high-resolution, wide-field optical photometry, and near-infrared photometry and spectroscopy from Euclid will be powerful for addressing a wide range of astrophysical questions. We explore Euclid/LSST synergy, ignoring the political issues associated with data access to focus on the scientific, technical, and financial benefits of coordination. We focus primarily on dark energy cosmology, but also discuss galaxy evolution, transient objects, solar system science, and galaxy cluster studies. We concentrate on synergies that require coordination in cadence or survey overlap, or would benefit from pixel-level co-processing that is beyond the scope of what is currently planned, rather than scientific programs that could be accomplished only at the catalog level without coordination in data processing or survey strategies. We provide two quantitative examples of scientific synergies: the decrease in photo-z errors (benefiting many science cases) when high-resolution Euclid data are used for LSST photo-z determination, and the resulting increase in weak-lensing signal-to-noise ratio from smaller photo-z errors. We briefly discuss other areas of coordination, including high-performance computing resources and calibration data. Finally, we address concerns about the loss of independence and potential cross-checks between the two missions and the potential consequences of not collaborating.
R & D on carbon nanostructures in Russia: scientometric analysis, 1990-2011

Terekhov, Alexander I.
2015-02-01
The analysis, based on scientific publications and patents, was conducted to form an understanding of the overall scientific and technology landscape in the field of carbon nanostructures and determine Russia's place on it. The scientific publications came from the Science Citation Index Expanded database (DB SCIE); the patent information was extracted from databases of the United States Patent and Trade Office (USPTO), the World Intellectual Property Organization (WIPO), and Russian Federal Service for Intellectual Property (Rospatent). We used also data about research projects, obtained via information systems of the U.S. National Science Foundation (NSF) and the Russian Foundation for Basic Research (RFBR). Bibliometric methods are used to rank countries, institutions, and scientists, contributing to the carbon nanostructures research. We analyze the current state and trends of the research in Russia as compared to other countries, and the contribution and impact of its institutions, especially research of the "highest quality." Considerable focus is on research collaboration and its relationship with citation impact. Patent datasets are used to determine the composition of participants of innovative processes and international patent activity of Russian inventors in the field, and to identify the most active representatives of small and medium business and some technological developments ripe for commercialization. The article contains a critical analysis of the findings, including a policy discussion of the country's scientific authorities.
Cross-Field Comparison of Ethics Education: Golden Rules and Particulars.
Mulhearn, Tyler J; Watts, Logan L; Torrence, Brett S; Todd, E Michelle; Turner, Megan R; Connelly, Shane; Mumford, Michael D
2017-01-01
Research misconduct negatively impacts the scientific community and society in general. Providing training in the responsible conduct of research (RCR) to researchers is one viable approach to minimizing research misconduct. Although recent evidence suggests ethics training can indeed be effective, little empirical work has examined the similarities and differences across fields. In the present study, we analyzed 62 empirical studies in engineering, biomedical science, social science, and mixed fields. The findings suggest certain instructional principles, or "golden rules," apply generally to all fields. These golden rules include maintaining a field-specific or field-general approach and emphasizing processes in training. The findings also suggest that content areas contributing to instructional effectiveness vary as a function of field. Generally, it appears that all fields may benefit from taking a multi-pronged approach to ethics education wherein the salient field issues are covered. Implications for RCR education are discussed.
A simple model of hysteresis behavior using spreadsheet analysis

Ehrmann, A.; Blachowicz, T.
2015-01-01
Hysteresis loops occur in many scientific and technical problems, especially as field dependent magnetization of ferromagnetic materials, but also as stress-strain-curves of materials measured by tensile tests including thermal effects, liquid-solid phase transitions, in cell biology or economics. While several mathematical models exist which aim to calculate hysteresis energies and other parameters, here we offer a simple model for a general hysteretic system, showing different hysteresis loops depending on the defined parameters. The calculation which is based on basic spreadsheet analysis plus an easy macro code can be used by students to understand how these systems work and how the parameters influence the reactions of the system on an external field. Importantly, in the step-by-step mode, each change of the system state, compared to the last step, becomes visible. The simple program can be developed further by several changes and additions, enabling the building of a tool which is capable of answering real physical questions in the broad field of magnetism as well as in other scientific areas, in which similar hysteresis loops occur.

The configuration of the Brazilian scientific field.
Barata, Rita B; Aragão, Erika; de Sousa, Luis E P Fernandes; Santana, Taris M; Barreto, Mauricio L
2014-03-01
This article describes the configuration of the scientific field in Brazil, characterizing the scientific communities in every major area of knowledge in terms of installed capacity, ability to train new researchers, and capacity for academic production. Empirical data from several sources of information are used to characterize the different communities. Articulating the theoretical contributions of Pierre Bourdieu, Ludwik Fleck, and Thomas Kuhn, the following types of capital are analyzed for each community: social capital (scientific prestige), symbolic capital (dominant paradigm), political capital (leadership in S & T policy), and economic capital (resources). Scientific prestige is analyzed by taking into account the volume of production, activity index, citations, and other indicators. To characterize symbolic capital, the dominant paradigms that distinguish the natural sciences, the humanities, applied sciences, and technology development are analyzed theoretically. Political capital is measured by presidency in one of the main agencies in the S & T national system, and research resources and fellowships define the economic capital. The article discusses the composition of these different types of capital and their correspondence to structural capacities in various communities with the aim of describing the configuration of the Brazilian scientific field.
Stem Cell Trials for Cardiovascular Medicine: Ethical Rationale
Teraa, Martin; Hesam, Husna; van Delden, Johannes J.M.; Verhaar, Marianne C.; Bredenoord, Annelien L.
2014-01-01
Stem cell-based interventions provide new treatment prospects for many disease conditions, including cardiovascular disorders. Clinical trials are necessary to collect adequate evidence on (long-term) safety and efficacy of novel interventions such as stem cells, but the design and launch of clinical trials, from first-in-human studies to larger randomized controlled trials (RCTs), is scientifically and ethically challenging. Stem cells are different from traditional pharmaceuticals, surgical procedures, and medical devices in the following ways: the novelty and complexity of stem cells, the invasiveness of the procedures, and the novel aim of regeneration. These specifics, combined with the characteristics of the study population, will have an impact on the design and ethics of RCTs. The recently closed JUVENTAS trial will serve as an example to identify the (interwoven) scientific and ethical challenges in the design and launch of stem cell RCTs. The JUVENTAS trial has investigated the efficacy of autologous bone marrow cells in end-stage vascular patients, in a double-blind sham-controlled design. We first describe the choices, considerations, and experiences of the JUVENTAS team. Subsequently, we identify the main ethical and scientific challenges and discuss what is important to consider in the design of future stem cell RCTs: assessment of risks and benefits, the choice for outcome measures, the choice for the comparator, the appropriate selection of participants, and adequate informed consent. Additionally, the stem cell field is highly in the spotlight due to the (commercial) interests and expectations. This warrants a cautious pace of translation and scrupulous set up of clinical trials, as failures could put the field in a negative light. At the same time, knowledge from clinical trials is necessary for the field to progress. We conclude that in the scientifically and ethically challenging field of stem cell RCTs, researchers and clinicians have to maneuver between the Skylla of hyper accelerated translation without rigorously conducted RCTs and the Charybdis of the missed opportunity of valuable knowledge.

There is a need to organize rehabilitation and related research into distinct scientific fields in order to overcome the current limitations of rehabilitation research. Based on the general distinction in basic, applied and professional sciences applicable to research in general, and the rehabilitation relevant distinction between the comprehensive perspective based on WHO's integrative model of human functioning (ICF) and the partial perspective focusing on the biomedical aspects of functioning, it is possible to identify 5 distinct scientific fields of human functioning and rehabilitation research. These are the emerging human functioning sciences and integrative rehabilitation sciences from the comprehensive perspective, the established biosciences and biomedical rehabilitation sciences and engineering from the partial perspective, and the professional rehabilitation sciences at the cutting edge of research and practice. The human functioning sciences aim to understand human functioning and to identify targets for comprehensive interventions, with the goal of contributing to the minimization of the experience of disability in the population. The biosciences in rehabilitation aim to explain body injury and repair and to identify targets for biomedical interventions. The integrative rehabilitation sciences design and study comprehensive assessments and interventions that integrate biomedical, personal factor and environmental approaches suited to optimize people's performance. The biomedical rehabilitation sciences and engineering study diagnostic measures and interventions suitable to minimize impairment, including symptom control, and to optimize people's capacity. The professional rehabilitation sciences study how to provide best care with the goal of enabling people with health conditions experiencing or likely to experience disability to achieve and maintain optimal functioning in interaction with the environment. The organization of human functioning and rehabilitation research into the 5 distinct scientific fields facilitates the development of academic training programs and career building as well as the development of research structures dedicated to human functioning and rehabilitation research.
The state of rehabilitation research: art or science?
Tate, Denise G
2006-02-01
Rehabilitation research has been criticized as not standing up enough to the rigors of scientific method to be called "science." The field has been portrayed as slow to promote its scientific achievements and to include them under the rubric of evidence-based rehabilitation. Following in the footsteps of psychology, rehabilitation as a broad-based discipline has faced many similar obstacles in achieving scientific status. Controversy exists about what exactly constitutes rehabilitation science versus its art and its respective multidisciplinary domains. The conception of these domains is directly related to current methods available to assess the state of the discipline and its research accomplishments. I used quantitative methods, such as randomized clinical and/or controlled trials (RCTs) and systematic reviews, to assess the status of rehabilitation research. Findings suggest that, as a field, rehabilitation makes significant contributions to science, measurable by the number and quality of RCTs and systematic reviews conducted so far on topics of critical importance for clinical care. In "artful" complement, qualitative approaches can be used as research tools to aid investigators in seeking knowledge beyond that obtained by quantitative methods, assessing many complexities associated with the various contexts of rehabilitation research. Other requirements to develop a common vision of rehabilitation science are also discussed.

Course-based undergraduate research experiences (CUREs) have been developed to overcome barriers including students in research. However, there are few examples of CUREs that take place in a conservation and natural resource context with students engaging in field research. Here, we highlight the development of a conservation-focused CURE integrated to a research program, research benefits, student self-assessment of learning, and perception of the CURE. With the additional data, researchers were able to refine species distribution models and facilitate management decisions. Most students reported gains in their scientific skills, felt they had engaged in meaningful, real-world research. In student reflections on how this experience helped clarify their professional intentions, many reported being more likely to enroll in graduate programs and seek employment related to science. Also interesting was all students reported being more likely to talk with friends, family, or the public about wildlife conservation issues after participating, indicating that courses like this can have effects beyond the classroom, empowering students to be advocates and translators of science. Field-based, conservation-focused CUREs can create meaningful conservation and natural resource experiences with authentic scientific teaching practices.

This investigation delineates a multi-year action research agenda designed to develop an instructional model for teaching the nature of science (NOS) to preservice science teachers. Our past research strongly supports the use of explicit reflective instructional methods, which includes Thomas Kuhn’s notion of learning by ostention and treating science as a continuum (i.e., comparing fields of study to one another for relative placement as less to more scientific). Instruction based on conceptual change precepts, however, also exhibits promise. Thus, the investigators sought to ascertain the degree to which conceptual change took place among students (n = 15) participating in the NOS instructional model. Three case studies are presented to illustrate successful conceptual changes that took place as a result of the NOS instructional model. All three cases represent students who claim a very conservative Christian heritage and for whom evolution was not considered a legitimate scientific theory prior to participating in the NOS instructional model. All three case study individuals, along with their twelve classmates, placed evolution as most scientific when compared to intelligent design and a fictional field of study called “Umbrellaology.”

The Alaska Summer Research Academy (ASRA) annually provides the opportunity for ~150 exceptional high school students to engage in scientific exploration at the university level. In July 2012, University of Alaska Fairbanks instructors led a two-week long ASRA module, called 'Denali Geographic', where eight student participants from across the USA and Canada learned how to observe changes in the natural world and design their own experiments for a field expedition to Denali National Park and Preserve, with assistance from the National Park Service. Each student designed an experiment/observational project prior to the expedition to investigate changes across the expanse of the park. Projects included wildlife documentation; scat and track observations; soil ph and moisture with elevation and vegetation changes; wildflowers species distribution; waterborne insect populations; atmospheric pressure and temperature variations; construction of sustainable buildings to minimize human impact on the park; and park geology comparisons between outcrop and distal stream deposits. The students learned how to design experiments, purchase supplies needed to conduct the work, and select good locations in which to sample in the park. Students used equipment such as GPS to mark field locations; a range finder to determine distance from wildlife; a hygrometer for temperature and pressure; nets and sorting equipments to analyze insects; and the preparation of Plaster of Paris for creating casts of animal tracks. All observations were documented in their field notebooks and blog entries made to share their experiences. Day excursions as part of the module included Poker Flats Research Range, where students learned about the use of unmanned aerial vehicles in scientific exploration; Alaska Volcano Observatory, where students learned about volcanic hazards in Alaska and the North Pacific; Chena Hot Springs and the Ice Museum, where students learned about thermal imaging using a Forward Looking Infrared Radiometer; and Pioneer Park to learn how to pan for gold. After the completion of the expedition, students had to then synthesize each of their research projects and create a collaborative presentation of their findings. On the final day of the camp, students delivered a presentation to 150 of their peers and instructors in the other ASRA modules. Presented here are details of the field camp and experiences gained by the students. The camp and two-week long module showed students how to pursue their own curiosities about the natural world. By encouraging students to take an idea and develop it into a research topic, we engaged them in the scientific method and illustrated possibilities for future avenues of academic study.

NASA’s Frontier Fields is an ambitious three-year Great Observatories program that will expand our understanding of galaxy formation and evolution in the early universe. The program includes six deep-field observations of strong-lensing galaxy clusters that will be taken in parallel with six deep “blank fields.” The observations allow astronomers to look deeper into the universe than ever before, and potentially uncover galaxies that are as much as 100 times fainter than what the telescopes can typically observe. The Frontier Fields science program is ideal for informing audiences about scientific advances and topics in STEM. The study of galaxy properties, statistics, optics, and Einstein’s theory of general relativity naturally leverages off of the science returns of the Frontier Fields program. As a result, the Space Telescope Science Institute’s Office of Public Outreach (OPO) has initiated an E/PO project to follow the progress of the Frontier Fields.For over two decades, the Hubble E/PO program has sought to bring the wonders of the universe to the education community, the youth, and the public, and engage audiences in the adventure of scientific discovery. Program components include standards-based curriculum-support materials, exhibits and exhibit components, professional development workshops, and direct interactions with scientists. We are also leveraging our new social media strategy to bring the science program to the public in the form of an ongoing blog. The main underpinnings of the program’s infrastructure are scientist-educator development teams, partnerships, and an embedded program evaluation component. OPO is leveraging this existing infrastructure to bring the Frontier Fields science program to the education community and the public in a cost-effective way.This talk features the goals and current status of the Frontier Fields E/PO program, with a particular emphasis on our education goals and achievements. We also highlight OPO’s strategies and infrastructure which allows for the quick delivery of groundbreaking science to the education community and public.
Socio-economic applications of finite state mean field games.
Gomes, Diogo; Velho, Roberto M; Wolfram, Marie-Therese
2014-11-13
In this paper, we present different applications of finite state mean field games to socio-economic sciences. Examples include paradigm shifts in the scientific community or consumer choice behaviour in the free market. The corresponding finite state mean field game models are hyperbolic systems of partial differential equations, for which we present and validate different numerical methods. We illustrate the behaviour of solutions with various numerical experiments, which show interesting phenomena such as shock formation. Hence, we conclude with an investigation of the shock structure in the case of two-state problems. © 2014 The Author(s) Published by the Royal Society. All rights reserved.

The aim of this study was to discuss the limits of the quantitative evaluation model for scientific production in Public Health. An analysis of the scientific production of professors from the various subareas of Public Health was performed for 2010-2012. Distributions of the mean annual score for professors were compared according to subareas. The study estimated the likelihood that 60% of the professors in the graduate studies programs scored P50 (Very Good) or higher in their area. Professors of Epidemiology showed a significantly higher median annual score. Graduate studies programs whose faculty included at least 60% of Epidemiology professors and fewer than 10% from the subarea Social and Human Sciences in Health were significantly more likely to achieve a "Very Good" classification. The observed inequalities in scientific production between different subareas of Public Health point to the need to rethink their evaluation in order to avoid reproducing iniquities that have harmful consequences for the field's diversity.

Students have many difficulties in understanding to wave propagation. Such difficulties lead to misconceptions also in understanding sound, light, and electromagnetic wave. Meanwhile, students only use the text book as the learning resources. Whereas students need a more varied and interesting learning resources. This study aims to develop a wave encyclopaedia based on scientific approach as the learning resources that tested the feasibility and superiority. The method used is research by design. The steps are (1) analysing learner characteristic, (2) state objective, (3) select media and materials, (4) utilize materials, (5) requires learner participation, (6) evaluation and revision. The wave encyclopaedia is developed by applying the 5 components of a scientific approach that is, observing, questioning, experimenting, associating, and communicating. In this encyclopaedia also includes fun science activities and exciting recommended websites. The encyclopaedia has been validated by material experts, media experts, and learning experts. And then field trials are conducted to assess an impact on use. Overall the development of encyclopaedia based on scientific approach can enhance learning outcomes of students in high school.
Building sustainable neuroscience capacity in Africa: the role of non-profit organisations.
Karikari, Thomas K; Cobham, Ansa E; Ndams, Iliya S
2016-02-01
While advances in neuroscience are helping to improve many aspects of human life, inequalities exist in this field between Africa and more scientifically-advanced continents. Many African countries lack the infrastructure and appropriately-trained scientists for neuroscience education and research. Addressing these challenges would require the development of innovative approaches to help improve scientific competence for neuroscience across the continent. In recent years, science-based non-profit organisations (NPOs) have been supporting the African neuroscience community to build state-of-the-art scientific capacity for sustainable education and research. Some of these contributions have included: the establishment of training courses and workshops to introduce African scientists to powerful-yet-cost-effective experimental model systems; research infrastructural support and assistance to establish research institutes. Other contributions have come in the form of the promotion of scientific networking, public engagement and advocacy for improved neuroscience funding. Here, we discuss the contributions of NPOs to the development of neuroscience in Africa.

This essay presents a history of the scientific journal of the University of Puerto Rico, School of Tropical Medicine (STM) under the auspices of Columbia University: The Puerto Rico Journal of Public Health and Tropical Medicine. This is the third article in a historical series about the STM, and includes supporting information relevant to the forthcoming articles on the school's scientific endeavors. This article is conceived as a history from the perspective of the literature of journal genre in the field of tropical medicine. The STM scientific journal, precursor of the Puerto Rico Health Sciences Journal, had five main stages. First (1925-1927), originated as an official bulletin of the Health Department (Porto Rico Health Review). Second (1927-1929), became a project of mutual collaboration between the Health Department and the STM, and the publication's title reflected the fields of public health and tropical medicine. Third (1929-1932), acquired a scientific focus as it changed to a quarterly science publication. Fourth (1932-1942), became a fully bilingual journal and acquired its definitive name. Fifth (1942-1950), the final phase in which the first Puerto Rican Director became the principal editor until the Journal's dissolution. The analysis of authorship and the content analysis of the topics of diseases, public health and basic sciences, clarify the history of tropical medicine during the first half of the 20th century in Puerto Rico. The article highlights major symbolic events that delve into the understanding of a collaborative exemplar of the modernity of medical science.
Thermo Scientific Ozone Analyzer Instrument Handbook

Springston, S. R.
The primary measurement output from the Thermo Scientific Ozone Analyzer is the concentration of the analyte (O3) reported at 1-s resolution in units of ppbv in ambient air. Note that because of internal pneumatic switching limitations the instrument only makes an independent measurement every 4 seconds. Thus, the same concentration number is repeated roughly 4 times at the uniform, monotonic 1-s time base used in the AOS systems. Accompanying instrument outputs include sample temperatures, flows, chamber pressure, lamp intensities and a multiplicity of housekeeping information. There is also a field for operator comments made at any time while data ismore » being collected.« less

Consideration is given to a Martian exploration strategy which includes intensive robotic reconnaissance to characterize features of Mars' geology that are important to the solution of major problems of Mars history, including the possible past presence of life. A human reconnaissance phase may follow the robotic reconnaissance phase, guided to the most productive sites by the results of the robotic missions. The strategy also involves an intensive human phase of investigation, with interactive field geology/laboratory investigation at the Mars outpost. The laboratory investigations, as well as the field work, should be highly interactive with a broad scientific community on earth. The most detailed analyses would be performed on samples returned to earth.

The SETI Institute hosts a summer Astrobiology Research Experience for Undergraduates program for highly motivated students interested in astrobiology research. Students work with scientists at the SETI Institute and at the nearby NASA Ames Research Center on projects spanning the field of astrobiology from microbiology to planetary geology to astronomy and astrophysics. Each student is mentored by a scientist for his/her summer research project. As astrobiology is interdisciplinary, the first week includes a seminar series to provide a broad foundation in the field as the students begin their research projects. The 10-week program includes a week-long field trip to the SETI Institute’s Allen Telescope Array, located at the Hat Creek Radio Astronomy Observatory in Northern California, as well as a field experience at hydrothermal systems at nearby Lassen Volcanic National Park. Students also participate in local field trips to places like the California Academy of Sciences and other nearby locations of scientific interest, and attend seminars, lectures, and discussions on astrobiology. Students are also invited to attend events at nearby NASA Ames Research Center, which offers the opportunity to interact with other undergraduate and graduate students participating in NASA summer programs. At the end of the program, students write up and present their research projects, and mentors recommend some projects for submission to a national scientific conference, which the selected students will be funded to attend. The Astrobiology REU program emphasizes three main areas, which are listed in the table along with typical project themes. Each year, specific student research projects are described on the website, and students are asked to select the three that most interest them as a part of their applications. Applications are due in early February. Typically, 10 students apply for each available position. Students have been selected from colleges and universities national-wide, including community colleges. The Astrobiology REU program has served 4 classes of students, and is funded through summer of 2011. A total of 61 students have participated (12 in 2006, 17 in 2007, 17 in 2008, and 15 in 2009); all have successfully completed their internships. Of these students, 59% were women, and 21% were minorities. To date 18 students have gone on to graduate studies, in Master’s or PhD programs at schools including Harvard, UC Berkeley, UC Santa Cruz, Stanford, Univ. of Nebraska, and many others, in fields including astronomy, optical science, space life sciences, geology, physics, mechanical engineering, and molecular and cellular biology. The SETI Institute is a non-profit private scientific research institution located in California’s Silicon Valley.

The project included ground- and aircraft-based fieldwork in the European Arctic, as well as computer modelling. Our communication activities included: our own field blog (www.arcticmethane.wordpress.com), which was syndicated to the Scientific American Expeditions blog; writing articles for other blogs with a wider audience than our own; use of twitter; and podcasting our field work. The grand finale to our communications work was a live event at a science festival, in which we took the audience along with us on a recreated research flight, complete with a life-size mock up of a section of our research aircraft. I will discuss my experiences of these forms of communication, and give an evaluation of their successes and failures.

Backlighting of x-ray-driven implosions in empty hohlraums with mono-energetic protons on the OMEGA laser facility has allowed a number of important phenomena to be observed. Several critical parameters were determined, including plasma flow, three types of spontaneous electric fields and megaGauss magnetic fields. These results provide insight into important issues in indirect-drive ICF. Even though the cavity is effectively a Faraday cage, the strong, local fields inside the hohlraum can affect laser-plasma instabilities, electron distributions and implosion symmetry. They are of fundamental scientific importance for a range of new experiments at the frontiers of high-energy-density physics. Future experiments designed to characterize the field formation and evolution in low-Z gas fill hohlraums will be discussed.

Due to the increasing sophistication and miniaturization of computational components, complex, distributed systems of interacting agents are becoming ubiquitous. Such systems, where each agent aims to optimize its own performance, but where there is a well-defined set of system-level performance criteria, are called collectives. The fundamental problem in analyzing/designing such systems is in determining how the combined actions of self-interested agents leads to 'coordinated' behavior on a iarge scale. Examples of artificial systems which exhibit such behavior include packet routing across a data network, control of an array of communication satellites, coordination of multiple deployables, and dynamic job scheduling across a distributed computer grid. Examples of natural systems include ecosystems, economies, and the organelles within a living cell. No current scientific discipline provides a thorough understanding of the relation between the structure of collectives and how well they meet their overall performance criteria. Although still very young, research on collectives has resulted in successes both in understanding and designing such systems. It is eqected that as it matures and draws upon other disciplines related to collectives, this field will greatly expand the range of computationally addressable tasks. Moreover, in addition to drawing on them, such a fully developed field of collective intelligence may provide insight into already established scientific fields, such as mechanism design, economics, game theory, and population biology. This chapter provides a survey to the emerging science of collectives.

Traditional processing of Global Navigation Satellite System (GNSS) data using dedicated scientific software has provided the highest levels of positional accuracy, and has been used extensively in geophysical deformation studies. To achieve these accuracies a significant level of understanding and training is required, limiting their availability to the general scientific community. Various online GNSS processing services, now freely available, address some of these difficulties and allow users to easily process their own GNSS data and potentially obtain high quality results. Previous research into these services has focused on Continually Operating Reference Station (CORS) GNSS data. Less research exists on the results achievable with these services using large campaign GNSS data sets, which are inherently noisier than CORS data. Even less research exists on the quality of velocity fields derived from campaign GNSS data processed through online precise point positioning services. Particularly, whether they are suitable for geodynamic and deformation studies where precise and reliable velocities are needed. In this research, we process a very large campaign GPS data set (spanning 10 yr) with the online Jet Propulsion Laboratory Automated Precise Positioning Service. This data set is taken from a GNSS network specifically designed and surveyed to measure deformation through the central North Island of New Zealand. This includes regional CORS stations. We then use these coordinates to derive a horizontal and vertical velocity field. This is the first time that a large campaign GPS data set has been processed solely using an online service and the solutions used to determine a horizontal and vertical velocity field. We compared this velocity field to that of another well utilized GNSS scientific software package. The results show a good agreement between the CORS positions and campaign station velocities obtained from the two approaches. We discuss the implications of these results for how future GNSS campaign field surveys might be conducted and how their data might be processed.

The Aditya-L1 is first Indian solar mission scheduled to be placed in a halo orbit around the first Lagrangian point (L1) of Sun-Earth system in the year 2018-19. The approved scientific payloads onboard Aditya-L1 spacecraft includes a Fluxgate Digital Magnetometer (FGM) to measure the local magnetic field which is necessary to supplement the outcome of other scientific experiments onboard. The in-situ vector magnetic field data at L1 is essential for better understanding of the data provided by the particle and plasma analysis experiments, onboard Aditya-L1 mission. Also, the dynamics of Coronal Mass Ejections (CMEs) can be better understood with the help of in-situ magnetic field data at the L1 point region. This data will also serve as crucial input for the short lead-time space weather forecasting models. The proposed FGM is a dual range magnetic sensor on a 6 m long boom mounted on the Sun viewing panel deck and configured to deploy along the negative roll direction of the spacecraft. Two sets of sensors (tri-axial each) are proposed to be mounted, one at the tip of boom (6 m from the spacecraft) and other, midway (3 m from the spacecraft). The main science objective of this experiment is to measure the magnitude and nature of the interplanetary magnetic field (IMF) locally and to study the disturbed magnetic conditions and extreme solar events by detecting the CME from Sun as a transient event. The proposed secondary science objectives are to study the impact of interplanetary structures and shock solar wind interaction on geo-space environment and to detect low frequency plasma waves emanating from the solar corona at L1 point. This will provide a better understanding on how the Sun affects interplanetary space. In this paper, we shall give the main scientific objectives of the magnetic field experiment and brief technical details of the FGM onboard Aditya-1 spacecraft.

Implementation science for the prevention and treatment of HIV/AIDS.
Schackman, Bruce R
2010-12-01
Implementation science is the scientific study of methods to promote the integration of research findings and evidence-based interventions into health care policy and practice and hence to improve the quality and effectiveness of health services and care. Implementation science is distinguished from monitoring and evaluation by its emphasis on the use of the scientific method. The origins of implementation science include operations research, industrial engineering, and management science. Today, implementation science encompasses a broader range of methods and skills including decision science and operations research, health systems research, health outcomes research, health and behavioral economics, epidemiology, statistics, organization and management science, finance, policy analysis, anthropology, sociology, and ethics. Examples of implementation science research are presented for HIV prevention (prevention of mother-to-child transmission of HIV, male circumcision) and HIV and drug use (syringe distribution, treating drug users with antiretroviral therapy and opioid substitution therapy). For implementation science to become an established field in HIV/AIDS research, there needs to be better coordination between funders of research and funders of program delivery and greater consensus on scientific research approaches and standards of evidence.

UNAVCO has been providing infrastructure and support for solid-earth sciences and earthquake natural hazards for the past two decades. Recent advances in GNSS technology and data processing are now providing position solutions with centimeter-level precision at high-rate (>1 Hz) and low latency (i.e. the time required for data to arrive for analysis, in this case less than 1 second). These data have the potential to improve our understanding in diverse areas of geophysics including properties of seismic, volcanic, magmatic and tsunami sources, and thus profoundly transform rapid event characterization and warning. Scientific and operational applications also include glacier and ice sheet motions; tropospheric modeling; and space weather. These areas of geophysics represent a spectrum of research fields, including geodesy, seismology, tropospheric weather, space weather and natural hazards. Processed Real-Time GNSS (RT-GNSS) data will require formats and standards that allow this broad and diverse community to use these data and associated meta-data in existing research infrastructure. These advances have critically highlighted the difficulties associated with merging data and metadata between scientific disciplines. Even seemingly very closely related fields such as geodesy and seismology, which both have rich histories of handling large volumes of data and metadata, do not go together well in any automated way. Community analysis strategies, or lack thereof, such as treatment of error prove difficult to address and are reflected in the data and metadata. In addition, these communities have differing security, accessibility and reliability requirements. We propose some solutions to the particular problem of making RT-GNSS processed solution data and metadata accessible to multiply scientific and natural hazard communities. Importantly, we discuss the roadblocks encounter and solved and those that remain to be addressed.
Pavia, September, 1961: a window on muscles and nerves
Mazzarello, Paolo
2012-01-01
Summary In September 1961, the First International Congress of Electromyography (EMG) was held at the University of Pavia. This event proved to be a sort of foundation stone for the further development of EMG as an organized field. Many of the most distinguished clinical neurophysiologists attended this congress and took an active part in it, delivering important lectures and scientific communications on the various aspects of EMG, including electroneurography. They included: Henri Gastaut, Fritz Buchthal, Jean Edouard Desmedt, Eric Kugelberg, Roger W. Gilliatt, John A. Simpson, Albrecht Struppler, Irena Hausmanowa-Petrusewicz, and Howard Edward Lambert. The congress was organized by Paolo Pinelli, at the time a young and brilliant clinical neurophysiologist who had learned the EMG procedure in Copenhagen under the guidance of Fritz Buchthal. Various scientific and social aspects of this important congress are outlined in this paper. PMID:22687169
Evolution of magnetic therapy from alternative to traditional medicine.
Vallbona, C; Richards, T
1999-08-01
Static or electromagnetic fields have been used for centuries to control pain and other biologic problems, but scientific evidence of their effect had not been gathered until recently. This article explores the value of magnetic therapy in rehabilitation medicine in terms of static magnetic fields and time varying magnetic fields (electromagnetic). A historical review is given and the discussion covers the areas of scientific criteria, modalities of magnetic therapy, mechanisms of the biologic effects of magnetic fields, and perspectives on the future of magnetic therapy.

NetworkX is a Python language package for exploration and analysis of networks and network algorithms. The core package provides data structures for representing many types of networks, or graphs, including simple graphs, directed graphs, and graphs with parallel edges and self loops. The nodes in NetworkX graphs can be any (hashable) Python object and edges can contain arbitrary data; this flexibility mades NetworkX ideal for representing networks found in many different scientific fields. In addition to the basic data structures many graph algorithms are implemented for calculating network properties and structure measures: shortest paths, betweenness centrality, clustering, and degree distributionmore » and many more. NetworkX can read and write various graph formats for eash exchange with existing data, and provides generators for many classic graphs and popular graph models, such as the Erdoes-Renyi, Small World, and Barabasi-Albert models, are included. The ease-of-use and flexibility of the Python programming language together with connection to the SciPy tools make NetworkX a powerful tool for scientific computations. We discuss some of our recent work studying synchronization of coupled oscillators to demonstrate how NetworkX enables research in the field of computational networks.« less

Climates of risk: a field analysis of global climate change in US media discourse, 1997-2004.
Sonnett, John
2010-11-01
How are industry and environmentalist discourses of climate risk related to dominant scientific and political discourses? This study operationalizes Bourdieu's concept of symbolic capital in order to map dimensions of risk description and prescription onto a journalistic field of industry, environmentalist, scientific, and political media. Results show that conventional definitions of risk mirror an opposition between scientific and political discourses. Prescriptions for action on risk are partly autonomous from definitions however. Environmentalist and scientific media feature more proactive discourse, and industry and political media feature more reactive discourse. Implications for future research on climate risk and relational studies of media discourse are discussed.

While traditional geologic mapping includes the examination of structural relationships between rock units in the field, more advanced technology now enables us to simultaneously collect and combine analytical datasets with field observations. Information about tectonomagmatic processes can be gleaned from these combined data products. Historically, construction of multi-layered field maps that include sample data has been accomplished serially (first map and collect samples, analyze samples, combine data, and finally, readjust maps and conclusions about geologic history based on combined data sets). New instruments that can be used in the field, such as a handheld xray fluorescence (XRF) unit, are now available. Targeted use of such instruments enables geologists to collect preliminary geochemical data while in the field so that they can optimize scientific data return from each field traverse. Our study tests the application of this technology and projects the benefits gained by real-time geochemical data in the field. The integrated data set produces a richer geologic map and facilitates a stronger contextual picture for field geologists when collecting field observations and samples for future laboratory work. Real-time geochemical data on samples also provide valuable insight regarding sampling decisions by the field geologist

Following the 2005-6 chikungunya outbreak, a project to strengthen regional Public Health preparedness in the Indian Ocean was implemented. It includes the Comoros, Madagascar, Mauritius, Reunion (France) and Seychelles. A Field Epidemiology Training Programme (FETP-OI) was started in 2011 to develop a pool of well-trained intervention epidemiologists. The FETP-OI consists of two years of supervised, learning-by-doing, on-the-job training at national sites involved in disease surveillance and response. It includes work placements at the Madagascar Pasteur Institute and the French regional epidemiology unit in Reunion and up to three training courses per year. Training objectives include epidemiological surveillance, outbreak investigations, research studies, scientific communication and transfer of competencies. In four years, two cohorts of in total 15 fellows originating from four countries followed the FETP-OI. They led 42 surveillance projects (71% routine management, 14% evaluations, 12% setup, 3% other) and investigated 36 outbreak alerts, 58% of them in Madagascar; most investigations (72%) concerned foodborne pathogens, plague or malaria. Fellows performed 18 studies (44% descriptive analyses, 22% disease risk factors, and 34% on other subjects), and presented results during regional and international conferences through 26 oral and 15 poster presentations. Four articles were published in regional Public Health bulletins and several scientific manuscripts are in process. The FETP-OI has created a regional force of intervention consisting of field epidemiologists and trained supervisors using the same technical language and epidemiological methods. The third cohort is now ongoing. Technically and financially sustainable FETP-OI projects help addressing public health priorities of the Indian Ocean.

Research in medicine is liable to all rules and standards that apply to research in other natural sciences, since medicine as a science and service fully meets the general definition of science: it is a common, integrated, organized and systematized knowledge of mankind, whereby physician--being more or less aware of doing so-- in his daily activities applies scientific thinking and scientific methods. The procedure of problem solving in scientific work and in medical practice is characterized by many similarities as well as variation. In scientific research, the observation of some phenomenon that cannot be explained by the known facts and theories is followed by making a hypothesis, planning and carrying out experimental investigation resulting in some data. Interpretation of these data then provides evidence to confirm or reject the hypothesis. In medical practice, quite a similar procedure is followed; the initial examination of a patient, when his condition cannot be explained by the data thus obtained, is identical to the observation of a phenomenon which cannot be explained by the known facts; working diagnosis would correspond to making the hypothesis; and experimental investigation would compare to laboratory and other diagnostic studies. The working diagnosis is accepted or rejected depending on these results. Of course, there also are differences in the problem solving procedure between scientific research and daily medical practice. For example, in research a single hypothesis is posed, a single experiment with successive testing and/or repeats is performed, whereas in medical practice several hypotheses are made, multiple studies are concurrently performed to reject current hypotheses and to make new ones. Scientific investigation produces an abundance of systematic data, whereas in medical practice target data are being generated, yet not systematically. Definitive decision making also differs greatly, as in scientific research it only ensues from conclusive evidence, whereas in medical practice definitive decision is made and therapeutic procedures are performed even before reaching final evidence. The general strategy of work and research in medicine can be briefly described by four principles, i.e. good knowledge of one's own work; continuing upgrading of one's own work in collaboration with respective institutions (laboratories, university, and research institutes); implementation of standard, up-to-date and scientific methods most of the time; and publishing work results on a regular basis. This strategy ensures constant progress and treatment quality improvement while allowing due validation and evaluation of the work by the society. Scientific research is based on the pre-existing knowledge of the problem under study, and should be supervised, systematic and planned. Research produces data that may represent some new concepts, or such concepts are developed by further data processing. In research, scientific procedure includes a number of steps that have to be made to reach a new scientific result. This procedure includes (a) thinking about a scientific issue; (b) making a scientific hypothesis, i.e. the main objective of the study; (c) research ethics; (d) determination of sources and mode of data collection; (e) research performance; (f) collection and analysis of all research data; (g) interpretation of results and evidence; and (h) publications. The next section of this chapter brings an example of scientific research in the field of medicine, where the procedures carried out during the research are briefly described; other chapters of this supplement deal with statistical methodology used on processing the data obtained in the study, which is most frequently employed in scientific work in the field of medicine.
The future of HIV vaccine research and the role of the Global HIV Vaccine Enterprise.
Voronin, Yegor; Manrique, Amapola; Bernstein, Alan
2010-09-01
This review covers the role of the Global HIV Vaccine Enterprise (the Enterprise), an alliance of independent organizations committed to development of a safe and effective HIV vaccine. It discusses the history, impact on the field, and future directions and initiatives of the alliance in the context of recent progress in HIV vaccine research and development. Significant progress has been made in the field since the release of the 2005 Scientific Strategic Plan (the Plan) of the Enterprise. Over the last year, the Enterprise embarked on an impact assessment of the 2005 Plan and the development of the 2010 Plan. Enterprise Working Groups identified key priorities in the field, several of which are discussed in this review, including changing the nature, purpose and process of clinical trials, increasing and facilitating data sharing, and optimizing existing and mobilizing new resources. This time is an important moment in HIV vaccine research. New clinical trial and laboratory results have created new opportunities to advance the search for an HIV vaccine and reinvigorated the field. The Enterprise will publish its 2010 Plan this year, providing a framework for setting new priorities and directions and encouraging new and existing partners to embark on a shared scientific agenda.

The magnetometer is one of the most important payloads of scientific satellites to monitor the near-earth space environment. The electromagnetic variations of the space environment can be observed with the electric and magnetic field measurements. In practice, it is well known that the measurement of magnetic fields needs less technical complexities than that of electric fields in space. Therefore the magnetometer has long been recognized as one of the basic payloads for the scientific satellites. In this paper, we discuss the scientific fluxgate magnetometer which will be on board the KITSAT-3. The main circuit design of the present magnetometer is based on that of KISAT-1 and -2 but its facilities have been re-designed to improve the resolution to about 5nT for scientific purpose. The calibration and noise level test of this circuit have been performed at the laboratory of the Tierra Tecnica company in Japan.

The Global Registry of Scientific Collections (GRSciColl) is an online information resource developed to gather and disseminate basic information on scientific collections. Building on initiatives started for biological collections, GRSciColl expands this framework to encompass all scientific disciplines including earth and space sciences, anthropology, archaeology, biomedicine, and applied fields such as agriculture and technology. The goals of this registry are to (1) provide a single source of synoptic information about the repositories, their component collections, access and use policies, and staff contact information; and (2) facilitate the assignment of identifiers for repositories and their collections that are globally unique across all disciplines. As digitization efforts continue, the importance of globally unique identifiers is paramount to ensuring interoperability across datasets. Search capabilities and web services will significantly increase the web visibility and accessibility of these collections. Institutional records include categorization by governance (e.g., national, state or local governmental, private non-profit) and by scientific discipline (e.g., earth science, biomedical, agricultural). Collection-level metadata categorize the types of contained specimens/samples and modes of preservation. In selecting the level of granularity for these categories, designers sought a compromise that would capture enough information to be useful in searches and inquiries and would complement the detailed archives in specimen-level databases such (which are increasingly digital) hosted by discipline-specific groups (e.g. SESAR) or the repositories themselves (e.g. KE EMu).

We introduce here the inaugural issue of the new scientific journal Translation. The overarching aim of this endeavor is to establish a new forum for a broad spectrum of research in the area of protein synthesis in living systems ranging from structural biochemical, evolutionary and regulatory aspects of translation to the fundamental questions related to post-translational control of somatic phenomena in multicellular organisms including human behavior and health. The journal will publish high quality research articles, provide novel insights, ask provocative questions and discuss new hypothesis in this emerging field. Launching a new journal is always challenging. We hope that strong criteria for the peer-review process, transparency of the editorial policy and the scientific reputation of its founders, editors and editorial board assure the success of Translation; and we rely on continuing support of the scientific community in all aspects of the journal’s activity.

The 13th ERS Lung Science Conference (LSC) was organised to bring academics together from all over the world to present and discuss the latest developments regarding lung infection and immunity. The conference took place in breathtaking Estoril, Portugal; however, it wasn't the beautiful surroundings that were our main motivation to attend, but instead the scientific merit of the conference and the chance to create new scientific collaborations. The scientific programme [1] was packed with the most up-to-date content in the field of lung infection and immunity and included some of the top researchers within this exciting area. Moreover, the convenient size of the LSC offered the opportunity to renew and intensify friendships and collaborations. In particular, for researchers at the start of their career, this is a great feature and we therefore warmly recommend the LSC to ERS Juniors Members!

The combination of high-cadence, deep, wide-field optical photometry from LSST with high-resolution, wide-field optical photometry, and near-infrared photometry and spectroscopy from Euclid will be powerful for addressing a wide range of astrophysical questions. We explore Euclid/LSST synergy, ignoring the political issues associated with data access to focus on the scientific, technical, and financial benefits of coordination. We focus primarily on dark energy cosmology, but also discuss galaxy evolution, transient objects, solar system science, and galaxy clustermore » studies. We concentrate on synergies that require coordination in cadence or survey overlap, or would benefit from pixel-level co-processing that is beyond the scope of what is currently planned, rather than scientific programs that could be accomplished only at the catalog level without coordination in data processing or survey strategies. Also, we provide two quantitative examples of scientific synergies: the decrease in photo-z errors (benefiting many science cases) when high-resolution Euclid data are used for LSST photo-z determination, and the resulting increase in weak-lensing signal-to-noise ratio from smaller photo-z errors. We briefly discuss other areas of coordination, including high-performance computing resources and calibration data. Finally, we address concerns about the loss of independence and potential cross-checks between the two missions and the potential consequences of not collaborating.« less

Research has tremendously contributed to the developments in both practical and fundamental aspects of limb prosthetics. These advancements are reflected in scientific articles, particularly in the most cited papers. This article aimed to identify the 100 top-cited articles in the field of limb prosthetics and to investigate their main characteristics. Articles related to the field of limb prosthetics and published in the Web of Knowledge database of the Institute for Scientific Information (ISI) from the period of 1980 to 2012. The 100 most cited articles in limb prosthetics were selected based on the citation index report. All types of articles except for proceedings and letters were included in the study. The study design and level of evidence were determined using Sackett's initial rules of evidence. The level of evidence was categorized either as a systematic review or meta-analysis, randomized controlled trial, cohort study, case-control study, case series, expert opinion, or design and development. The top cited articles in prosthetics were published from 1980 to 2012 with a citation range of 11 to 90 times since publication. The mean citation rate was 24.43 (SD 16.7) times. Eighty-four percent of the articles were original publications and were most commonly prospective (76%) and case series studies (67%) that used human subjects (96%) providing level 4 evidence. Among the various fields, rehabilitation (47%), orthopedics (29%), and sport sciences (28%) were the most common fields of study. The study established that studies conducted in North America and were written in English had the highest citations. Top cited articles primarily dealt with lower limb prosthetics, specifically, on transtibial and transradial prosthetic limbs. Majority of the articles were experimental studies.

Scientifically defensible predictions of field scale U(VI) transport in groundwater requires an understanding of key processes at multiple scales. These scales range from smaller than the sediment grain scale (less than 10 μm) to as large as the field scale which can extend over several kilometers. The key processes that need to be considered include both geochemical reactions in solution and at sediment surfaces as well as physical transport processes including advection, dispersion, and pore-scale diffusion. The research summarized in this report includes both experimental and modeling results in batch, column and tracer tests. The objectives of this research weremore » to: (1) quantify the rates of U(VI) desorption from sediments acquired from a uranium contaminated aquifer in batch experiments;(2) quantify rates of U(VI) desorption in column experiments with variable chemical conditions, and(3) quantify nonreactive tracer and U(VI) transport in field tests.« less

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.

Research involving human embryos and reproductive materials, including certain forms of stem cell and genetic research, is a fast-moving area of science with demonstrated clinical relevance. Canada's current governance framework for this field of research urgently requires review and reconsideration in view of emerging applications. Based on a workshop involving ethics, legal, policy, scientific and clinical experts, we present a series of recommendations with the goal of informing and supporting health policy and decision-making regarding the governance of the field. With a pragmatic and principled governance approach, Canada can continue its global leadership in this field, as well as advance the long-term health and well-being of Canadians. PMID:29595433

The study is based on the methodology of the contemporary interdisciplinary cognitive images of the information entity of the surgical sphere, reflected in the phenomenology of the journal "Surgery", which is gathering --as a publication of the Scientific Society of Surgeons--the kaleidoscope of the genealogy of the scientific and practical thought in Bulgaria in the treated area for an impressive historical lapse of time. The information image observed is represented in the form of a triptych: I. Macrostructure of the periodicals in the field of medicine in the years 30 of XX century: Bibliographic analysis: Historiographical description [: Background]; II. Microstructure of the journal "Surgery" (1934-2004): Periodization [1934-1944: non-party system with priority of the monarchy; 1944-1989: totalitarian epoch; 1989-2004: democracy and pluralism]: Scientometrical synthesis: Transformatism of the information modeling [: History]; III. Status of the surgical field in the intelligible prism of the journal "Surgery" (1934-2004): Interdisciplinary deduction: Cognitological proscopy [: Classification]. The ontological synthesis concludes the study by which is expressed the systemic dynamical entity of the relation "surgical field"--"its scientific expression in a periodical" as a base of future scientific research--as well as a complex scientific and applied field of knowledge, and a social important phenomenon. The Supplements and References and notes are an empirical base and a fragment of the expose.
National Geomagnetism Program: Current Status & Five-Year Plan, 2006-2010
Love, Jeffrey J.
2006-01-01
Executive Summary: The U.S. Geological Survey's Geomagnetism Program serves the scientific community and the broader public by collecting and distributing magnetometer data from an array of ground-based observatories and by conducting scientific analysis on those data. Preliminary, variational time-series can be collected and distributed in near-real time, while fully calibrated, absolute time-series are distributed after processing. The data are used by the civilian and military parts of the Federal Government, by private industry, and by academia, for a wide variety of purposes of both immediately practical importance and long-term scientific interest, including space-weather diagnosis and related hazard mitigation, mapping of the magnetic field and measurement of its activity, and research on the nature of the Earth's interior and the near-Earth space environment. This document reviews the current status of the Program, in terms of its situation within the Government and within the scientific community; summarizes the Program's operations, its staffing situation, and its facilities; describes the diversity of uses of Program magnetometer data; and presents a plan for the next 5 years for enhancing the Program's data-based services, developing products, and conducting scientific research.

Dr. Albert's current research is centered on transfer processes in porous media, including air-snow exchange in the Polar Regions and in soils in temperate areas. Her research includes field measurements, laboratory experiments, and theoretical modeling. Mary conducts field and laboratory measurements of the physical properties of natural terrain surfaces, including permeability, microstructure, and thermal conductivity. Mary uses the measurements to examine the processes of diffusion and advection of heat, mass, and chemical transport through snow and other porous media. She has developed numerical models for investigation of a variety of problems, from interstitial transport to freezing of flowing liquids. These models include a two-dimensional finite element code for air flow with heat, water vapor, and chemical transport in porous media, several multidimensional codes for diffusive transfer, as well as a computational fluid dynamics code for analysis of turbulent water flow in moving-boundary phase change problems.
Scientific misconduct: also an issue in nursing science?

Scientific misconduct (SMC) is an increasing concern in nursing science. This article discusses the prevalence of SMC, risk factors and correlates of scientific misconduct in nursing science, and highlights interventional approaches to foster good scientific conduct. Using the "Fostering Research Integrity in Europe" report of the European Science Foundation as a framework, we reviewed the literature in research integrity promotion. Although little empirical data exist regarding prevalence of scientific misconduct in the field of nursing science, available evidence suggests a similar prevalence as elsewhere. In studies of prospective graduate nurses, 4% to 17% admit data falsification or fabrication, while 8.8% to 26.4% report plagiarizing material. Risk factors for SMC exist at the macro, meso, and micro levels of the research system. Intervention research on preventing scientific misconduct in nursing is limited, yet findings from the wider field of medicine and allied health professions suggest that honor codes, training programs, and clearly communicated misconduct control mechanisms and misconduct consequences improve ethical behavior. Scientific misconduct is a multilevel phenomenon. Interventions to decrease scientific misconduct must therefore target every level of the nursing research systems. Scientific misconduct not only compromises scientific integrity by distorting empirical evidence, but it might endanger patients. Because nurses are involved in clinical research, raising their awareness of scientifically inappropriate behavior is essential. © 2014 Sigma Theta Tau International.

With the completion of scientific studies undertaken as part of the 1998 Mallik 2L-38 gas hydrate research well, an international research site was established for the study of Arctic natural gas hydrates in the Mackenzie Delta of northwestern Canada. Quantitative well log analysis and core studies reveal multiple gas hydrate layers from 890 m to 1106 m depth, exceeding 110 m in total thickness. High gas hydrate saturation values, which in some cases exceed 80% of the pore volume, establish the Mallik gas hydrate field as one of the most concentrated gas hydrate reservoirs in the world. Beginning in December 2001 and continuing to the middle of March 2002, two 1188 m deep science observation wells were drilled and instrumented and a 1166 m deep production research well program was carried out. The program participants include 8 partners; The Geological Survey of Canada (GSC), The Japan National Oil Corporation (JNOC), GeoForschungsZentrum Potsdam (GFZ), United States Geological Survey (USGS), United States Department of the Energy (USDOE), India Ministry of Petroleum and Natural Gas (MOPNG)/Gas Authority of India (GAIL) and the Chevron-BP-Burlington joint venture group. In addition the project has been accepted as part of the International Scientific Continental Drilling Program. The Geological Survey of Canada is coordinating the science program for the project and JAPEX Canada Ltd. acted as the designated operator for the fieldwork. Primary objectives of the research program are to advance fundamental geological, geophysical and geochemical studies of the Mallik gas hydrate field and to undertake advanced production testing of a concentrated gas hydrate reservoir. Full-scale field experiments in the production well monitored the physical behavior of the hydrate deposits in response to depressurization and thermal stimulation. The observation wells facilitated cross-hole tomography and vertical seismic profile experiments (before and after production) as well as the measurement of in situ formation conditions. A wide- ranging science and engineering research program included the collection of gas-hydrate-bearing core samples and downhole geophysical logging. Laboratory and modeling studies undertaken during the field program, and subsequently as part of a post-field research program, will document the sedimentology, physical/petrophysical properties, geochemistry, geophysics, reservoir characteristics and production behavior of the Mallik gas hydrate accumulation. The research team, including some 100 participant scientists from over 20 institutes in 7 countries, expects to publish the scientific results in 2004.
Concise Review: The U.S. Food and Drug Administration and Regenerative Medicine.
Witten, Celia M; McFarland, Richard D; Simek, Stephanie L

Regenerative medicine (RM) is a popular term for a field of scientific and medical research. There is not one universally accepted definition of RM, but it is generally taken to mean the translation of multidisciplinary biology and engineering science into therapeutic approaches to regenerate, replace, or repair tissues and organs. RM products have the potential to provide treatments for a number of unmet needs but have substantial scientific and regulatory challenges that need to be addressed for this potential to be fully realized. FDA has established formal regulatory definitions for biologics, medical devices, and combination products, as well as human cells and tissues. Regenerative medicine products regulated by FDA are classified on the basis of these definitions, and the classification forms the basis for determining the regulatory requirements to each specific product. FDA regulations are generally written to allow the agency flexibility to accommodate new scientific questions raised by novel and evolving technologies. FDA efforts to facilitate product development in this novel and promising area include working with individual sponsors, interacting with the scientific and industry communities, participating in standards development, and developing policy and guidance. Regenerative medicine is generally taken to mean the translation of multidisciplinary biology and engineering science into therapeutic approaches to regenerate, replace, or repair tissues and organs. This article provides an overview of the efforts of the U.S. Food and Drug Administration (FDA) to facilitate product development in the field commonly known was regenerative medicine. It provides an introduction to the processes by which FDA works with individual sponsors, interacts with the scientific and industry communities, participates in standards development, and develops formal FDA policy and guidance. ©AlphaMed Press.

The early NASA international scientific and technical information exchange arrangements were usually detailed in correspondence with the librarians of the institutions involved. While this type of exchange grew to include some 200 organizations in 43 countries, NASA's main focus shifted to the relationship with the European Space Agency (ESA), which began in 1964. The NASA/ESA Tripartite Exchange Program provides more than 4000 technical reports from the NASA-produced Aerospace Database. The experience in the evolving cooperation between NASA and ESA has established the model for more recent exchange agreements with Israel, Australia, and Canada. The results of these agreements are made available to participating European organizations through the NASA File.

Patent applications contain citations which are similar to but different from those found in published scientific papers. In particular, patent citations are governed by legal rules. Moreover, a large fraction of citations are made not by the patent inventor, but by a patent examiner during the application procedure. Using a patent database, which contains the patent citations, assignees and inventors, we have applied network analysis and built network models. Our work includes determining the structure of the patent citation network and comparing it to existing results for scientific citation networks; identifying differences between various technological fields and comparing the observed differences to expectations based on anecdotal evidence about patenting practice; and developing models to explain the results.

Space science missions, and astronomy missions in particular, capture the public imagination at all levels. ESA's Gaia mission is no exception to this. In addition to its key scientific goal of providing new insight into the origin, formation, and evolution of the Milky Way, Gaia also touches on many other scientific topics of broad appeal, for example, solar system objects, stars (including rare and exotic ones), dark matter, gravitational light bending. The mission naturally provides a rich resource for outreach possibilities whether it be to the general public, or to specific interest groups, such as scientists from other fields or educators. We present some examples of possible outreach activities for Gaia.

We present a 5-year NSF CAREER project incorporating educational outreach for high school science teachers. Teachers are integrated into field and research components of this project in order to provide the most meaningful and classroom-translatable experience. The associated research project is aimed at quantifying the strength and morphology of the Precambrian geomagnetic field via detailed paleomagnetic analyses of reliably dated mafic sequences known to contain pristine paleomagnetic records. Investigation of the geomagnetic field behavior is crucial for understanding the mechanisms of field generation, has important implications for the development of the Earth's atmosphere and biosphere, and can serve as a focus for connecting high-level Earth science research with a standard physics curriculum. Educational outreach objectives include developing effective methods for pre-college physics teachers to gain the experience and expertise to (1) use paleomagnetic research to motivate and help students understand the physics of magnetism, from microscopic to planetary scales; (2) transfer key experiences of scientific processes to classroom activities, specifically the skills of patience, innovation, flexibility, and collaboration; and (3) help students integrate mathematics and physics into logical problem-solving approaches. Because the teacher participants are directly involved with our research, they are able to provide significant contributions to project outreach and dissemination efforts. This year's work focused on sampling and analyzing mafic dikes from northern Wisconsin and Michigan. The summer phase featured a 3-week field/lab/classroom session. In week one, a 4-person field team (including two teacher participants) conducted field work - the small size of the team ensured that every participant gained skills on aspects of site location, rock identification, and paleomagnetic field procedures. During week two, participants gained proficiency at processing samples, magnetic characterization, and demagnetization experiments in an effort to characterize the orientation and strength of the Earth's magnetic field at the time of rock formation. In week three, the team analyzed data and developed classroom activities to transfer experiences to the pre-college physics classroom. Teacher researchers will work throughout the project's duration to apply and monitor the effectiveness of these efforts. During the next several years, new teams of teacher researchers will help advance this project with work in Arizona, Canada, and Minnesota, ending with a reunion of all participants back to Michigan Tech during the final year for an exchange of outcomes, both from the classroom and the university. Close collaboration with all cohorts will be maintained by participation at scientific and educational meetings, publication in research and education journals, etc. Outcomes from this outreach program will be made available to the scientific and education communities with the hope of creating an accessible and meaningful vehicle by which the intricacies of Earth magnetism can be conveyed to the next generation.

Building translational ecology communities of practice: insights from the field
Lawson, Dawn M.; Hall, Kimberly R.; Yung, Laurie; Enquist, Carolyn A. F.
2017-01-01
Translational ecology (TE) prioritizes the understanding of social systems and decision contexts in order to address complex natural resource management issues. Although many practitioners in applied fields employ translational tactics, the body of literature addressing such approaches is limited. We present several case studies illustrating the principles of TE and the diversity of its applications. We anticipate that these examples will help others develop scientific products that decision makers can use “off the shelf” when solving critical ecological and social challenges. Our collective experience suggests that research of such immediate utility is rare. Long‐term commitment to working directly with partners to develop and reach shared goals is central to successful translation. The examples discussed here highlight the benefits of translational processes, including actionable scientific results, more informed policy making, increased investment in science‐driven solutions, and inspiration for partnerships. We aim to facilitate future TE‐based projects and build momentum for growing this community of practice.
Research briefing on high-temperature superconductivity
NASA Astrophysics Data System (ADS)
1987-10-01
The research briefing was prepared in response to the exciting developments in superconductivity in ceramic oxide materials announced earlier in 1987. The panel's specific charge was to examine not only the scientific opportunities in high-temperature superconductivity but also the barriers to commercial exploitation. While the base of experimental knowledge on the superconductors is growing rapidly, there is as yet no generally accepted theoretical explanation of their behavior. The fabrication and processing challenges presented by the materials suggest that the period or precommercial exploration for applications will probably extend for a decade or more. Near term prospects for applications include magnetic shielding, the voltage standard, superconducting quantum interference devices, infrared sensors, microwave devices, and analog signal processing. The panel also identified a number of longer-term prospects in high-field and large-scale applications, and in electronics. The United States' competitive position in the field is discussed, major scientific and technological objectives for research and development identified, and concludes with a series of recommendations.

Using traditional bibliometric indices such as the well-known journal impact factor (IFAC), as well as other more recently developed measures like the (journal) h-index and modifications, we assessed the impact of most prolific scientific journals in the field of animal and dairy science. To achieve this end, we performed a detailed investigation on the evaluation of journals quality, using a total of 50 journals selected from the category of "Agriculture, Dairy & Animal Science" included in the Thomson Reuters' (formerly Institute of Scientific Information, ISI) Web of Science. Our analysis showed that among the top journals in the field are the Journal of Dairy Research, the Journal of Dairy Science, and the Journal of Animal Science. In particular, the Journal of Animal Science, the most productive and frequently cited journal, has shown rapid development, especially in recent years. The majority of the top-tier, highly cited articles are those associated with the description of statistical methodology and the standard chemical analytical methodologies.
[Defining AIDS terminology. A practical approach].
Locutura, Jaime; Almirante, Benito; Berenguer, Juan; Muñoz, Agustín; Peña, José María
2003-01-01
Since the appearance of AIDS, the study of this disease has generated a large amount of information and an extensive related vocabulary comprised of new terms or terms borrowed from other scientific fields. The urgent need to provide names for newly described phenomena and concepts in this field has resulted in the application of terms that are not always appropriate from the linguistic and scientific points of view. We discuss the difficulties in attempting to create adequate AIDS terminology in the Spanish language, considering both the general problems involved in building any scientific vocabulary and the specific problems inherent to this activity in a field whose defining illness has important social connotations. The pressure exerted by the predominance of the English language in reporting scientific knowledge is considered, and the inappropriate words most often found in a review of current literature are examined. Finally, attending to the two most important criteria for the creation of new scientific terms, accuracy and linguistic correction, we propose some well thought-out alternatives that conform to the essence of the Spanish language.

This article discusses to what extent risk analysis is scientific in view of a set of commonly used definitions and criteria. We consider scientific knowledge to be characterized by its subject matter, its success in developing the best available knowledge in its fields of study, and the epistemic norms and values that guide scientific investigations. We proceed to assess the field of risk analysis according to these criteria. For this purpose, we use a model for risk analysis in which science is used as a base for decision making on risks, which covers the five elements evidence, knowledge base, broad risk evaluation, managerial review and judgment, and the decision; and that relates these elements to the domains experts and decisionmakers, and to the domains fact-based or value-based. We conclude that risk analysis is a scientific field of study, when understood as consisting primarily of (i) knowledge about risk-related phenomena, processes, events, etc., and (ii) concepts, theories, frameworks, approaches, principles, methods and models to understand, assess, characterize, communicate, and manage risk, in general and for specific applications (the instrumental part). © 2014 Society for Risk Analysis.

Recently, several food refrigeration equipments that utilize magnetic field have attracted much attention from food production companies, consumers and mass media. However, the effectiveness of the freezers is not scientifically examined. Therefore, the effectiveness should be clarified by experiments or theoretical considerations. In this study, the effect of weak magnetic field (about 0.0005 T) on freezing process of several kinds of foods was investigated by using a specially designed freezer facilitated with magnetic field generator. The investigation included the comparison of freezing curves, drip amount, physicochemical evaluations on color and texture, observation of microstructure, and sensory evaluation. From the results of the control experiments, it can be concluded that weak magnetic field around 0.0005 T provided no significant difference on temperature history during freezing and on the qualities of frozen foods, within our experimental conditions.

The AKARI FU-HYU mission program has carried out mid-infrared imaging of several well studied Spitzer fields. This imaging fills in the wavelength coverage lacking from the Spitzer surveys and gives an extremely high scientific return for minimal input for AKARI. We select fields already rich in multi-wavelength data from radio to X-ray wavelengths and present the results from our initial analysis in the GOODS-N field. We utilize the comprehansive multiwavelength coverage in the GOODS-N field to produce a multiwavelength catalogue from infrared to ultraviolet wavelengths including photometric redshifts. Using the FU-HYU catalogue we present colour-colour diagrams that map the passage of PAH features through our observation bands. These colour-colours diagrams are used as tools to extract anomalous colour populations, in particular a population of Silicate Break galaxies from the GOODS-N field.

Recent developments in molecular methods have revolutionized the detection and characterization of microorganisms in a broad range of medical diagnostic fields, including virology, mycology, parasitology, microbiology and dentistry. Among these methods, Polymerase Chain Reaction (PCR) has generated great benefits and allowed scientific advancements. PCR is an excellent technique for the rapid detection of pathogens, including those difficult to culture. Along with conventional PCR techniques, Real-Time PCR has emerged as a technological innovation and is playing an ever-increasing role in clinical diagnostics and research laboratories. Due to its capacity to generate both qualitative and quantitative results, Real-Time PCR is considered a fast and accurate platform. The aim of the present literature review is to explore the clinical usefulness and potential of both conventional PCR and Real-Time PCR assays in diverse medical fields, addressing its main uses and advances.

Particle Demagnetization in Collisionless Magnetic Reconnection

Hesse, Michael
2006-01-01
The dissipation mechanism of magnetic reconnection remains a subject of intense scientific interest. On one hand, one set of recent studies have shown that particle inertia-based processes, which include thermal and bulk inertial effects, provide the reconnection electric field in the diffusion region. In this presentation, we present analytical theory results, as well as 2.5 and three-dimensional PIC simulations of guide field magnetic reconnection. We will show that diffusion region scale sizes in moderate and large guide field cases are determined by electron Larmor radii, and that analytical estimates of diffusion region dimensions need to include description of the heat flux tensor. The dominant electron dissipation process appears to be based on thermal electron inertia, expressed through nongyrotropic electron pressure tensors. We will argue that this process remains viable in three dimensions by means of a detailed comparison of high resolution particle-in-cell simulations.
Cultivating the field of psychology. Psychological journals at the turn of the century and beyond.
Johnson, D F
2000-10-01
Prominent psychologists, including G. Stanley Hall, James Mark Baldwin, and James McKeen Cattell, cultivated the field of psychological publishing with privately owned and managed journals. Hall's journals, including the American Journal of Psychology and Pedagogical Seminary, reflected his view of psychology as the empirical study of human nature and his support for applied psychology. Baldwin and Cattell's periodicals, including Psychological Review and Psychological Monographs, reflected a narrower scientific and academic view of psychology. Baldwin and Cattell were more successful editors than Hall and strategically linked their journals to the American Psychological Association (APA). The Psychological Review journals were purchased by APA in 1925. The narrower vision represented in these journals may have contributed to applied psychologists' dissatisfaction with APA during the late 1920s and early 1930s.

Scientific publishing, including in the field of Rheumatology, is evolving rapidly. Predatory journals are one of the major threats to contemporary publishing, especially to eager and naïve authors. In this narrative review, we discuss mechanisms that authors can employ to white list genuine scientific journals and blacklist "predatory" ones. Inclusion of a journal in reputed indices such as Medline (but not just Pubmed), Web of Science, Scopus or Embase raises the likelihood that the journal is genuine, more so if it is included in the current Journal Citation Reports. Other commercially available whitelists also exist, so also whitelists published by regulatory authorities in some countries. A commercially available blacklist has emerged since the very useful Beall's blacklist became defunct. In the absence of access to a whitelist or blacklist, certain characteristics such as repeated email solicitations for articles with an extremely narrow deadline from unknown sources, lack of inclusion in reputed indices, journals not published or endorsed by national or international society and scarcity of currently published articles should render authors suspicious of the genuine nature of a journal. National societies should work together to generate subject-specific (including Rheumatology specific) whitelists that can be available free of cost to authors from all over the world.

The European Space Agency's Planck satellite, which is dedicated to studying the early Universe and its subsequent evolution, was launched on 14 May 2009. It scanned the microwave and submillimetre sky continuously between 12 August 2009 and 23 October 2013. In February 2015, ESA and the Planck Collaboration released the second set of cosmology products based ondata from the entire Planck mission, including both temperature and polarization, along with a set of scientific and technical papers and a web-based explanatory supplement. This paper gives an overview of the main characteristics of the data and the data products in the release, as well as the associated cosmological and astrophysical science results and papers. The data products include maps of the cosmic microwave background (CMB), the thermal Sunyaev-Zeldovich effect, diffuse foregrounds in temperature and polarization, catalogues of compact Galactic and extragalactic sources (including separate catalogues of Sunyaev-Zeldovich clusters and Galactic cold clumps), and extensive simulations of signals and noise used in assessing uncertainties and the performance of the analysis methods. The likelihood code used to assess cosmological models against the Planck data is described, along with a CMB lensing likelihood. Scientific results include cosmological parameters derived from CMB power spectra, gravitational lensing, and cluster counts, as well as constraints on inflation, non-Gaussianity, primordial magnetic fields, dark energy, and modified gravity, and new results on low-frequency Galactic foregrounds.

The Nexus for Exoplanet System Science (NExSS) is a NASA-funded research coordination network whose focus is on investigating exoplanet diversity and devising strategies for searching for life on exoplanets. The fields of exoplanets and astrobiology are inherently highly interdisciplinary. Progress in these fields demands that researchers with various scientific backgrounds understand the issues and techniques of allied fields of study, including the tools and approaches used to solve different problems, as well as their limitations.In 2016, the NExSS teams at Arizona State University (ASU) and University of Arizona (UA) hosted 32 graduate students and postdoctoral researchers from various scientific backgrounds for one week at the Arizona NExSS Winter School. To bridge the gaps between fields and promote interdisciplinarity, students participated in lessons, field trips, hands-on activities, and a capstone proposal-writing activity. To assess the impact of the School on knowledge and attitudes about other fields, we administered a pre- and post-School questionnaire designed using the Impact Analysis Method of Davis & Scalice (2015).The results show that all participants gained knowledge at the School, especially in areas outside their primary field of study. The questionnaire revealed interesting differences in attitudes as well. When asked whether the geochemistry of Earth without life is predictable, planetary scientists were more likely than average to say yes, and geologists were more likely than average to say no. Their attitudes had converged after participation in the School. These results demonstrate that the Arizona NExSS Winter School was impactful not just in the knowledge gained, but in the interdisciplinary attitudes of students.
Electronic medical records for otolaryngology office-based practice.
Chernobilsky, Boris; Boruk, Marina
2008-02-01
Pressure is mounting on physicians to adopt electronic medical records. The field of health information technology is evolving rapidly with innovations and policies often outpacing science. We sought to review research and discussions about electronic medical records from the past year to keep abreast of these changes. Original scientific research, especially from otolaryngologists, is lacking in this field. Adoption rates are slowly increasing, but more of the burden is shouldered by physicians despite policy efforts and the clear benefits to third-party payers. Scientific research from the past year suggests lack of improvements and even decreasing quality of healthcare with electronic medical record adoption in the ambulatory care setting. The increasing prevalence and standardization of electronic medical record systems results in a new set of problems including rising costs, audits, difficulties in transition and public concerns about security of information. As major players in healthcare continue to push for adoption, increased effort must be made to demonstrate actual improvements in patient care in the ambulatory care setting. More scientific studies are needed to demonstrate what features of electronic medical records actually improve patient care. Otolaryngologists should help each other by disseminating research about improvement in patient outcomes with their systems since current adoption and outcomes policies do not apply to specialists.
[The concept and importance of medical law].
Jakovljević, Branislava; Segedi, Dimitrije
2006-01-01
Medical law is a scientific discipline which has not been affirmed in our country, but at law schools in many developed countries it has gained the status of a separate scientific discipline and today it is studied with multidisciplinary cooperation of Schools of Medicine, Schools of Dentistry and Schools of Pharmacy. Generally speaking, medical law concerns the rights and duties of the medical profession. The progress of scientific research and of new technology used in diagnostics and treatment, opens new fields in terms of responsibility. Most European countries have legal institutions in the field of health care. These include laws and legal acts, as well as codification of professional norms. Apart from the national law, there is also an international law concerning physisians. The World Health Organization and the World Association of Medical Doctors brought the following declarations: Declaration on Promotion of Patients' Rights, the Revised Lisbon Declaration on Patients' Rights, the Revised Helsinki Declaration on Biomedical Research Involving Human Subjects and the Council of Europe's Convention on Human Rights and Biomedicine. There is no national order of physicians in Serbia and Montenegro, because chambers of physicians with legal authority and mandatory membership have not been formed. The foundation of Chambers of Physicians of Vojvodina and Montenegro is the first step to goal achieving.

New treatment options such as noninvasive brain stimulation have been recently explored in the field of substance use disorders (SUDs), including transcranial direct current stimulation (tDCS). In light of this, we have performed a review of the scientific literature to assess efficacy and technical and methodological issues resulting from applying tDCS to the field of SUDs. Our analysis highlighted the following selection criteria: clinical studies on tDCS and SUDs (alcohol, caffeine, cannabis, cocaine, heroin, methamphetamine, and nicotine). Study selection, data analysis, and reporting were conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Exclusion criteria were as follows: clinical studies about tDCS among behavioral addiction; review and didactic articles; physiopathological studies; and case reports. Eighteen scientific papers were selected out of 48 articles. Among these, 16 studied the efficacy of tDCS applied to the dorsolateral prefrontal cortex, and 8 suggested the efficacy of tDCS in reducing substance craving. In light of these data, it is premature to conclude that tDCS over the dorsolateral prefrontal cortex is a very efficient technique in reducing craving. Small sample size, different stimulation protocols, and study duration were the main limitations. However, the efficacy of tDCS in treating SUDs requires further investigation.

The AfricaArray-Bushveld REU is a partnership between the Pennsylvania State University and the University of the Witwatersrand. The primary goal is to engage a diverse cohort of students in international scientific collaboration through a program of training, field work, and laboratory and/or computational analysis. At least 50% of the student participants each year are from under-represented minorities. Students spend 2-3 weeks at Penn State, then 3 weeks in South Africa, followed by another 2-3 weeks in the US. The introductory 2-3 week session at Penn State is devoted to ethics and safety training, the human history, culture, and geologic history of South Africa, and Earth Science Literacy. Upon arriving in South Africa, the students are placed into field groups with students, post-docs, and faculty from Wits and other African nations participating in the AfricaArray Geophysics Field School. Each disciplinary group includes at least 1 mentor from the US and 1 from South Africa. Students spend time collecting rock samples for geochemical analysis, installing and servicing seismometers, and/or collecting data from the shallow subsurface using a variety of geophysical techniques. All students attend lectures by faculty at Wits, receive training in proper use and maintenance of scientific instrumentation, and interact with industry representatives. The culmination of this part of the REU is a day of oral presentations, where all students (REU and AfricaArray Geophysics Field School) share their experiences and data. After returning to the US, students engage in geochemical analysis, processing of seismic data, and modeling geophysical data. In addition to faculty mentors, the students work closely with graduate students and post-docs. All participate in mentor-led discussions about future career paths and graduate school options. As a capstone to the REU, each student writes a conference abstract and gives a poster presentation of their research. Each abstract includes co-authors from the US and South Africa, and these have been presented by students at SACNAS, NABG, GSA, and AGU meetings. At the end of the REU, students participating in anonymous surveys report feeling more confident in their ability to contribute to an international scientific collaboration and to complete a graduate degree in geosciences.

Cognitive decline is recognized as a prevalent and debilitating symptom of multiple sclerosis (MS), especially deficits in episodic memory and processing speed. The field aims to (1) incorporate cognitive assessment into standard clinical care and clinical trials, (2) utilize state-of-the-art neuroimaging to more thoroughly understand neural bases of cognitive deficits, and (3) develop effective, evidence-based, clinically feasible interventions to prevent or treat cognitive dysfunction, which are lacking. There are obstacles to these goals. Our group of MS researchers and clinicians with varied expertise took stock of the current state of the field, and we identify several important practical and theoretical challenges, including key knowledge gaps and methodologic limitations related to (1) understanding and measurement of cognitive deficits, (2) neuroimaging of neural bases and correlates of deficits, and (3) development of effective treatments. This is not a comprehensive review of the extensive literature, but instead a statement of guidelines and priorities for the field. For instance, we provide recommendations for improving the scientific basis and methodologic rigor for cognitive rehabilitation research. Toward this end, we call for multidisciplinary collaborations toward development of biologically based theoretical models of cognition capable of empirical validation and evidence-based refinement, providing the scientific context for effective treatment discovery.

Scientific Performance Analysis of the SYZ Telescope Design versus the RC Telescope Design
NASA Astrophysics Data System (ADS)
Ma, Donglin; Cai, Zheng
2018-02-01
Recently, Su et al. propose an innovative design, referred as the “SYZ” design, for China’s new project of a 12 m optical-infrared telescope. The SYZ telescope design consists of three aspheric mirrors with non-zero power, including a relay mirror below the primary mirror. SYZ design yields a good imaging quality and has a relatively flat field curvature at Nasmyth focus. To evaluate the science-compatibility of this three-mirror telescope, in this paper, we thoroughly compare the performance of SYZ design with that of Ritchey–Chrétien (RC) design, a conventional two-mirror telescope design. Further, we propose the Observing Information Throughput (OIT) as a metric for quantitatively evaluating the telescopes’ science performance. We find that although a SYZ telescope yields a superb imaging quality over a large field of view, a two-mirror (RC) telescope design holds a higher overall throughput, a better diffraction-limited imaging quality in the central field of view (FOV < 5‧) which is better for the performance of extreme Adaptive Optics (AO), and a generally better scientific performance with a higher OIT value. D. Ma & Z. Cai contributed equally to this paper.
Learning in Authentic Earth and Planetary Contexts

A Virtual Field Trip project has been developed in collaboration with NASA Learning Technologies to allow students, internationally, to accompany scientists on a field trip to the Pilbara region of Western Australia to debate the relevance of ancient structures called stromatolites, to the origins of life on Earth and the search for life on Mars. The project was planned with the aim of exposing high school students to `science in the making', including exposure to the ongoing debate and uncertainties involved in scientific research. The development of the project stemmed from both research-based and anecdotal evidence that current science education programs are not providing secondary students with a good understanding of the processes of science. This study seeks to examine the effectiveness of student use of the tools to increase awareness of the processes of science and to evaluate the effectiveness of the tools in terms of student learning. The literature reports that there is a need for learning activities to be conducted within meaningful contexts. The virtual field trip tools create an environment that simulates key elements in the scientific process. Such an approach allows students to learn by doing, to work like scientists and apply their learning in an authentic context.

Shaw, Gordon A.
2018-07-01
This review article summarizes new scientific trends in research for metrology of small mass (1 mg and lower) and small force (10 micronewtons and lower). After a brief introduction to the field, this paper provides an overview of recent developments in methods that demonstrate traceability to the International System of Units (SI) with emphasis on the implications of redefining the kilogram in terms of Planck’s constant. Specific research applications include new metrology facilities, calibration of small mass and force references such as milligram to submilligram masses or atomic force microscope (AFM) cantilevers, and laser power measurement using radiation pressure forces. Also discussed are recent scientific developments that may impact the field moving forward in the study of ultrasmall forces present in trapped and cooled quantum mechanical systems, resonant micro- and nanomechanical mass sensors, and other areas that are potentially well suited for SI metrology. The work reviewed is not intended as a comprehensive review of all research in which small forces are measured, but rather as an overview of a field in which the accurate measurement of small mass and force with quantified uncertainty is the primary goal.

Intense research effort over last few decades in low-temperature (or cold) atmospheric plasma application in bioengineering led to the foundation of a new scientific field, plasma medicine. Cold atmospheric plasmas (CAP) produce various chemically reactive species including reactive oxygen species (ROS) and reactive nitrogen species (RNS). It has been found that these reactive species play an important role in the interaction of CAP with prokaryotic and eukaryotic cells triggering various signaling pathways in cells.

Beyond 2013 - The Future of European Scientific Drilling Research - An introduction.
NASA Astrophysics Data System (ADS)
Camoin, G.; Stein, R.
2009-04-01
The Integrated Ocean Drilling Program (IODP) is funded for the period 2003-2013, and is now starting to plan the future of ocean drilling beyond 2013, including the development of new technologies, new emerging research fields as and the societal relevance of this programme. In this context an interdisciplinary and multinational (USA, Europe, Japan, Asian and Oceanian countries), key conference - INVEST IODP New Ventures in Exploring Scientific Targets - addressing all international IODP partners is therefore planned for September 23rd-25th 2009 in Bremen, Germany (more information at http://www.iodp.org and http://marum.de/iodp-invest.html) to discuss future directions of ocean drilling research and related aspects such as ventures with related programmes or with industry. The first critical step of INVEST is to define the scientific research goals of the second phase of the Integrated Ocean Drilling Program (IODP), which is expected to begin in late 2013. INVEST will be open to all interested scientists and students and will be the principal opportunity for the international science community to help shape the future of scientific ocean drilling. The outcome of the conference will be the base to draft a science plan in 2010 and to define new goals and strategies to effectively meet the challenges of society and future ocean drilling. The current EGU Session and the related two days workshop which will be held at the University of Vienna will specifically address the future of European scientific drilling research. The major objectives of those two events are to sharpen the European interests in the future IODP and to prepare the INVEST Conference and are therefore of prime importance to give weight to the European propositions in the program renewal processes, both on science, technology and management, and to provide the participants with information about the status/process of ongoing discussions and negotiations regarding program structure, and provide them with the expected framework (available drilling platforms and anticipated funding levels). The key items that should be addressed during the EGU Session and the workshop will especially include : (1) The future of ECORD (science, technology, management). (2) New research initiatives and emerging fields in scientific drilling (3) Relationships between IODP and other programs (e.g. ICDP, IMAGES etc). (4) Collaboration between academia and industry. (5) New technologies and the Mission Specific Platform approach.

Intangible factors leading to success in research: strategy, innovation and leadership.
Hecker, Louise; Birla, Ravi K
2008-03-01
At the heart of research is the scientific process, which includes identifying a knowledge gap, execution of experiments, and finally, presentation of scientific data. Identifying a systematic way to undertake research is important; however, equally important are intangible factors, including strategy, innovation and leadership, in determining the outcome of any research project. These intangible factors, although often unspoken, are the essence of success in research. Strategy determines the direction of research and the ability to respond to acute changes in the field to ensure a competitive advantage. Innovation involves generating novel ideas, and at the heart of innovation is the ability to create a positive work environment. Leadership is the ability to exercise influence so as to create change; empowerment and the ability to create leaders at every level are central to effective leadership. Collectively, defining and implementing aspects of these intangible factors will strengthen any research endeavor.

PRIMA is a conceptual study for a single-baseline dual-feed instrument for the very large telescope interferometer, which is under construction by the European Southern Observatory on Cerro Paranal in Chile. The goals of PRIMA include narrow-angle astrometry with a precision of 10 (mu) as over an arc of 10 inches, and imaging of faint sources with the full sensitivity of the 8m telescopes in the VLT array. Key scientific programs that can be carried out with PRIMA in imaging mode include observations of active galactic nuclei, the Galactic Center, stars, and circumstellar matter. Scientific drivers for the astrometry are searches for planets and low-mass stellar companions, binary stars, dynamics of clusters, and parallaxes. We list the main performance requirements for PRIMA, present system architectures for the dual-beam system, and discuss limitations of the interferometric field-of-view.

This case study documents an example of inquiry learning and teaching during a summer institute for elementary and middle school teachers. A small group constructed an explanatory model for an intriguing optical phenomenon that they were observing. Research questions included: What physics thinking did the learners express? What aspects of scientific inquiry were evident in what the learners said and did? What questions did the learners ask one another as they worked? How did these learners collaborate in constructing understanding? How did the instructor foster their learning? Data sources included video- and audio- tapes of instruction, copies of the participants' writings and drawings, field notes, interviews, and staff reflections. An interpretative narrative of what three group members said and did presents a detailed account of their learning process. Analyses of their utterances provide evidence of physics thinking, scientific inquiry, questioning, collaborative sense making, and insight into ways to foster inquiry learning.

The Hubble Space Telescope continues to push the limits on world-class astrophysics. Cameras including the Advanced Camera for Surveys and the new panchromatic Wide Field Camera 3 which was installed nu last year's successful servicing mission S2N4,o{fer imaging from near-infrared through ultraviolet wavelengths. Spectroscopic studies of sources from black holes to exoplanet atmospheres are making great advances through the versatile use of STIS, the Space Telescope Imaging Spectrograph. The new Cosmic Origins Spectrograph, also installed last year, is the most sensitive UV spectrograph to fly io space and is uniquely suited to address particular scientific questions on galaxy halos, the intergalactic medium, and the cosmic web. With these outstanding capabilities on HST come complex needs for laboratory astrophysics support including atomic and line identification data. I will provide an overview of Hubble's current capabilities and the scientific programs and goals that particularly benefit from the studies of laboratory astrophysics.
SeaWiFS Science Algorithm Flow Chart

This flow chart describes the baseline science algorithms for the Sea-viewing Wide Field-of-view Sensor (SeaWiFS) Data Processing System (SDPS). As such, it includes only processing steps used in the generation of the operational products that are archived by NASA's Goddard Space Flight Center (GSFC) Distributed Active Archive Center (DAAC). It is meant to provide the reader with a basic understanding of the scientific algorithm steps applied to SeaWiFS data. It does not include non-science steps, such as format conversions, and places the greatest emphasis on the geophysical calculations of the level-2 processing. Finally, the flow chart reflects the logic sequences and the conditional tests of the software so that it may be used to evaluate the fidelity of the implementation of the scientific algorithm. In many cases however, the chart may deviate from the details of the software implementation so as to simplify the presentation.

We present a set of NASA and NSF sponsored resources to aid in teaching astronomy remotely and in the classroom at the college level, with usage results for pilot groups of students. Our goal is to increase the accessibility of general education science coursework to underserved populations nationwide. Our materials are available for use without charge, and we are actively looking for pilot instructors. Primary components of our program include an interactive online tutorial program with over 12,000 questions, an instructor review interface, a set of hands-on and imaging- and spectra-driven laboratory exercises, including video tutorials, and interviews with diverse individuals working in STEM fields to help combat stereotypes. We discuss learning strategies often employed by students without substantial scientific training and suggest ways to incorporate them into a framework based on the scientific method and techniques for data analysis, and we compare cohorts of in-class and distance-education students.

Scientific integrity: critical issues in environmental health research
Merlo, Domenico Franco; Vahakangas, Kirsi; Knudsen, Lisbeth E
2008-01-01
Environmental health research is a relatively new scientific area with much interdisciplinary collaboration. Regardless of which human population is included in field studies (e.g., general population, working population, children, elderly, vulnerable sub-groups, etc.) their conduct must guarantee well acknowledged ethical principles. These principles, along with codes of conduct, are aimed at protecting study participants from research-related undesired effects and guarantee research integrity. A central role is attributed to the need for informing potential participants (i.e., recruited subjects who may be enrolled in a study), obtaining their written informed consent to participate, and making them aware of their right to refuse to participate at any time and for any reason. Data protection is also required and communication of study findings must respect participant's willingness to know or not know. This is specifically relevant for studies including biological markers and/or storing biological samples that might be analysed years later to tackle research objectives that were specified and communicated to participants at the time of recruitment or that may be formulated after consent was obtained. Integrity is central to environmental health research searching for causal relations. It requires open communication and trust and any violation (i.e., research misconduct, including fabrication or falsification of data, plagiarism, conflicting interests, etc.) may endanger the societal trust in the research community as well as jeopardize participation rates in field projects.

A safe place to grow: Children, animals and caring in a life science classroom
NASA Astrophysics Data System (ADS)
Day, Leslie
The ecological systems of the earth are in crisis. The purpose of this study was to determine the impact an elementary school life science education program based on an ethic of care had on children's ability to value the natural world. It is a study of how care-based science education supports personal connections to animals and nature; and how strength-based science education emphasizes creativity as a means for students to explore and express scientific knowledge through the arts. This qualitative study was conducted in a life science classroom filled with a wide variety of animals: fish, amphibians, reptiles, birds, and mammals the students studied and developed caring relationships with. The participants were 55 fourth, fifth and sixth-grade students who spent two years studying the natural world both inside the classroom and outside in the field. Invertebrates, trees, birds, mammals and wildflowers were studied in fourth grade. Evolution, and the study of vertebrate animals, were studied in the fifth grade. As teacher researcher, I collected data including audio-taped interviews, observations, field notes, and artifacts including children's creative projects expressing their factual understanding and thoughts about the animals and the natural world. This study revealed themes reflecting children's caring for animals, scientific knowledge, creative expression of knowledge, and the natural world. The themes are illustrated through four "portraits of care" based on students' voices, experiences, and class-work. The findings indicate that caring relationships with animals supported personal connections to the natural world and scientific knowledge. Children had better understanding and retained knowledge due to their personal connections to the animals. The concepts of evolution and interdependence of living organisms enhanced their relationships with animals and nature. Through the arts, students expressed scientific knowledge in ways that had personal meaning and a high level of active engagement. Concerned about the environment, some students used their knowledge to affect the behavior of others by creating school newspapers and websites. Inasmuch as an ethic of care in life science supports personal connections to understanding and valuing the natural world, the implications include the recommendation that preservice and inservice science education should support these connections.
Evolution and structure of sustainability science.

The concepts of sustainable development have experienced extraordinary success since their advent in the 1980s. They are now an integral part of the agenda of governments and corporations, and their goals have become central to the mission of research laboratories and universities worldwide. However, it remains unclear how far the field has progressed as a scientific discipline, especially given its ambitious agenda of integrating theory, applied science, and policy, making it relevant for development globally and generating a new interdisciplinary synthesis across fields. To address these questions, we assembled a corpus of scholarly publications in the field and analyzed its temporal evolution, geographic distribution, disciplinary composition, and collaboration structure. We show that sustainability science has been growing explosively since the late 1980s when foundational publications in the field increased its pull on new authors and intensified their interactions. The field has an unusual geographic footprint combining contributions and connecting through collaboration cities and nations at very different levels of development. Its decomposition into traditional disciplines reveals its emphasis on the management of human, social, and ecological systems seen primarily from an engineering and policy perspective. Finally, we show that the integration of these perspectives has created a new field only in recent years as judged by the emergence of a giant component of scientific collaboration. These developments demonstrate the existence of a growing scientific field of sustainability science as an unusual, inclusive and ubiquitous scientific practice and bode well for its continued impact and longevity.

The growth and gaps of genetic data sharing policies in the United States
Arias, Jalayne J.; Pham-Kanter, Genevieve; Campbell, Eric G.
2014-01-01
The 1996 Bermuda Principles launched a new era in data sharing, reflecting a growing belief that the rapid public dissemination of research data was crucial to scientific progress in genetics. A historical review of data sharing policies in the field of genetics and genomics reflects changing scientific norms and evolving views of genomic data, particularly related to human subjects’ protections and privacy concerns. The 2013 NIH Draft Genomic Data Sharing (GDS) Policy incorporates the most significant protections and guidelines to date. The GDS Policy, however, will face difficult challenges ahead as geneticists seek to balance the very real concerns of research participants and the scientific norms that propel research forward. This article provides a novel evaluation of genetic and GDS policies’ treatment of human subjects’ protections. The article examines not only the policies, but also some of the most pertinent scientific, legal, and regulatory developments that occurred alongside data sharing policies. This historical perspective highlights the challenges that future data sharing policies, including the recently disseminated NIH GDS Draft Policy, will encounter. PMID:27774180

We present an initiative supported by the National Heart Lung, and Blood Institute and the Food and Drug Administration for the development of a repository containing continuous electrocardiographic information to be shared with the worldwide scientific community. We believe that sharing data reinforces open scientific inquiry. It encourages diversity of analysis and opinion while promoting new research and facilitating the education of new researchers. In this paper, we present the resources available in this initiative for the scientific community. We describe the set of ECG signals currently hosted and we briefly discuss the associated clinical information (medical history. Disease and study-specific endpoints) and software tools we propose. Currently, the repository contains more than 250GB of data from eight clinical studies including healthy individuals and cardiac patients. This data is available for the development, implementation and validation of technologies related to body-surface ECGs. To conclude, the Telemetric and Holter ECG Warehouse (THEW) is an initiative developed to benefit the scientific community and to advance the field of quantitative electrocardiography and cardiac safety.

Scientific research is increasingly collaborative and globally distributed; research groups now rely on web-based scientific tools and data management systems to simplify their day-to-day collaborative workflows. However, such tools often lack seamless interfaces, requiring researchers to contend with manual data transfers, annotation and sharing. MyGeoHub is a web platform that supports out-of-the-box, seamless workflows involving data ingestion, metadata extraction, analysis, sharing and publication. MyGeoHub is built on the HUBzero cyberinfrastructure platform and adds general-purpose software building blocks (GABBs), for geospatial data management, visualization and analysis. A data management building block iData, processes geospatial files, extracting metadata for keyword and map-based search while enabling quick previews. iData is pervasive, allowing access through a web interface, scientific tools on MyGeoHub or even mobile field devices via a data service API. GABBs includes a Python map library as well as map widgets that in a few lines of code, generate complete geospatial visualization web interfaces for scientific tools. GABBs also includes powerful tools that can be used with no programming effort. The GeoBuilder tool provides an intuitive wizard for importing multi-variable, geo-located time series data (typical of sensor readings, GPS trackers) to build visualizations supporting data filtering and plotting. MyGeoHub has been used in tutorials at scientific conferences and educational activities for K-12 students. MyGeoHub is also constantly evolving; the recent addition of Jupyter and R Shiny notebook environments enable reproducible, richly interactive geospatial analyses and applications ranging from simple pre-processing to published tools. MyGeoHub is not a monolithic geospatial science gateway, instead it supports diverse needs ranging from just a feature-rich data management system, to complex scientific tools and workflows.
Mission to the Moon: Europe's priorities for the scientific exploration and utilisation of the Moon

Battrick, Bruce; Barron, C.
1992-06-01
A study to determine Europe's potential role in the future exploration and utilization of the Moon is presented. To establish the scientific justifications the Lunar Study Steering Group (LSSG) was established reflecting all scientific disciplines benefitting from a lunar base (Moon studies, astronomy, fusion, life sciences, etc.). Scientific issues were divided into three main areas: science of the Moon, including all investigations concerning the Moon as a planetary body; science from the Moon, using the Moon as a platform and therefore including observatories in the broadest sense; science on the Moon, including not only questions relating to human activities in space, but also the development of artificial ecosystems beyond the Earth. Science of the Moon focuses on geographical, geochemical and geological observations of the Earth-Moon system. Science from the Moon takes advantage of the stable lunar ground, its atmosphere free sky and, on the far side, its radio quiet environment. The Moon provides an attractive platform for the observation and study of the Universe. Two techniques that can make unique cause of the lunar platform are ultraviolet to submillimeter interferometric imaging, and very low frequency astronomy. One of the goals of life sciences studies (Science on the Moon) is obviously to provide the prerequisite information for establishing a manned lunar base. This includes studies of human physiology under reduced gravity, radiation protection and life support systems, and feasibility studies based on existing hardware. The overall recommendations are essentially to set up specific study teams for those fields judged to be the most promising for Europe, with the aim of providing more detailed scientific and technological specifications. It is also suggested that the scope of the overall study activities be expanded in order to derive mission scenarios for a viable ESA lunar exploration program and to consider economic, legal and policy matters. The need for international coordination early in the study phase is emphasized.

Chudinova, V. G.; Bokova, O. R.
2017-11-01
The article presents the argumentation of the provision on the style-forming potential of the lighting design the sphere of which is interpreted in a wide range of genres. The area of the intersection of form-building technological and artistic aspects lies in the field of ecology which includes not only energy saving, but also the well-being of the human and the society. The theory and practice of designing the night-time image of architectural ensembles, buildings and landscapes develops much slower than the implementation of light solutions in the advertising industry. In most cases, the possibilities of lighting design are used only in the field of decorative lighting despite their huge aesthetic potential and rapidly improving technologies. The request for innovation and uniqueness usually arises on the basis of image and political ambitions of large corporations or for the positioning of powerful brands. The success of such projects becomes a driver for both creation and promotion of innovative solutions. However, in a broader scientific sense, not only the design of artificial light systems but also the optimization of the daylight usage falls into the sphere lighting design. The need for the new methods of architectural shaping is dictated by the need to introduce in the building of resource-saving lighting technologies, ecological infrastructure including alternative energy sources. The article gives the examples of different lighting design genres supplemented with illustrations. The conclusions concern the prospective directions and tasks of scientific research in the field of lighting design.

The nascent field of gravitational-wave astronomy offers many opportunities for effective and inspirational astronomy outreach. Gravitational waves, the ``ripples in space-time'' predicted by Einstein's theory of General Relativity, are produced by some of the most energetic and dramatic phenomena in the cosmos, including black holes, neutron stars and supernovae. The detection of gravitational waves will help to address a number of fundamental questions in physics, from the evolution of stars and galaxies to the origin of dark energy and the nature of space-time itself. Moreover, the cutting-edge technology developed to search for gravitational waves is pushing back the frontiers of many fields, from lasers and materials science to high performance computing, and thus provides a powerful showcase for the attractions and challenges of a career in science and engineering. For several years a worldwide network of ground-based laser interferometric gravitational-wave detectors has been fully operational, including the two LIGO detectors in the United States. These detectors are already among the most sensitive scientific instruments on the planet and in the next few years their sensitivity will achieve further significant improvement. Those developments promise to open an exciting new window on the universe, heralding the arrival of gravitational-wave astronomy as a revolutionary, new observational field. In this paper we describe the extensive program of public outreach activities already undertaken by the LIGO Scientific Collaboration, and a number of special events which we are planning for IYA2009.

The US Air Force Office of Scientific Research convened a meeting of researchers in the fields of neuroscience, psychology, engineering, and medicine to discuss most pressing issues facing ongoing research in the field of transcranial direct current stimulation (tDCS) and related techniques. In this study, we present opinions prepared by participants of the meeting, focusing on the most promising areas of research, immediate and future goals for the field, and the potential for hormesis theory to inform tDCS research. Scientific, medical, and ethical considerations support the ongoing testing of tDCS in healthy and clinical populations, provided best protocols are used to maximize safety. Notwithstanding the need for ongoing research, promising applications include enhancing vigilance/attention in healthy volunteers, which can accelerate training and support learning. Commonly, tDCS is used as an adjunct to training/rehabilitation tasks with the goal of leftward shift in the learning/treatment effect curves. Although trials are encouraging, elucidating the basic mechanisms of tDCS will accelerate validation and adoption. To this end, biomarkers (eg, clinical neuroimaging and findings from animal models) can support hypotheses linking neurobiological mechanisms and behavioral effects. Dosage can be optimized using computational models of current flow and understanding dose–response. Both biomarkers and dosimetry should guide individualized interventions with the goal of reducing variability. Insights from other applied energy domains, including ionizing radiation, transcranial magnetic stimulation, and low-level laser (light) therapy, can be prudently leveraged. PMID:28210202
Review of An Introduction to Parallel and Vector Scientific Computing
DOE Office of Scientific and Technical Information (OSTI.GOV)
Bailey, David H.; Lefton, Lew
2006-06-30
On one hand, the field of high-performance scientific computing is thriving beyond measure. Performance of leading-edge systems on scientific calculations, as measured say by the Top500 list, has increased by an astounding factor of 8000 during the 15-year period from 1993 to 2008, which is slightly faster even than Moore's Law. Even more importantly, remarkable advances in numerical algorithms, numerical libraries and parallel programming environments have led to improvements in the scope of what can be computed that are entirely on a par with the advances in computing hardware. And these successes have spread far beyond the confines of largemore » government-operated laboratories, many universities, modest-sized research institutes and private firms now operate clusters that differ only in scale from the behemoth systems at the large-scale facilities. In the wake of these recent successes, researchers from fields that heretofore have not been part of the scientific computing world have been drawn into the arena. For example, at the recent SC07 conference, the exhibit hall, which long has hosted displays from leading computer systems vendors and government laboratories, featured some 70 exhibitors who had not previously participated. In spite of all these exciting developments, and in spite of the clear need to present these concepts to a much broader technical audience, there is a perplexing dearth of training material and textbooks in the field, particularly at the introductory level. Only a handful of universities offer coursework in the specific area of highly parallel scientific computing, and instructors of such courses typically rely on custom-assembled material. For example, the present reviewer and Robert F. Lucas relied on materials assembled in a somewhat ad-hoc fashion from colleagues and personal resources when presenting a course on parallel scientific computing at the University of California, Berkeley, a few years ago. Thus it is indeed refreshing to see the publication of the book An Introduction to Parallel and Vector Scientic Computing, written by Ronald W. Shonkwiler and Lew Lefton, both of the Georgia Institute of Technology. They have taken the bull by the horns and produced a book that appears to be entirely satisfactory as an introductory textbook for use in such a course. It is also of interest to the much broader community of researchers who are already in the field, laboring day by day to improve the power and performance of their numerical simulations. The book is organized into 11 chapters, plus an appendix. The first three chapters describe the basics of system architecture including vector, parallel and distributed memory systems, the details of task dependence and synchronization, and the various programming models currently in use - threads, MPI and OpenMP. Chapters four through nine provide a competent introduction to floating-point arithmetic, numerical error and numerical linear algebra. Some of the topics presented include Gaussian elimination, LU decomposition, tridiagonal systems, Givens rotations, QR decompositions, Gauss-Seidel iterations and Householder transformations. Chapters 10 and 11 introduce Monte Carlo methods and schemes for discrete optimization such as genetic algorithms.« less

Research projects now rely on various pillars which include of course high level science and equipments, and also communication, outreach and educational activities. This paper focuses on education for young children and present activities that aim at helping them (and their parents!) to grasp some of the complex underlying scientific issues in the field of environment. More generally it helps children to get familiarized with science and scientists, with the hope of enhancing scientific culture and promoting careers in this field. The activities which are part of the popularization effort of the NEW Interreg IV RainGain project (www.raingain.eu) : - Experiments led in classrooms of kinder garden to design and test a disdrometer made of a plate and flour or oil to observe the diversity of rain drop sizes. It simply consists in putting a bit (roughly 1 mm depth) of flour or oil in a plate. The features of the devices based either flour or oil were first studied inside with artificial drops. Then it was tested outside under actual rain. - The writing of scientific book with and for children aged 8-9 years with the help of the editor of the collection. The process leading to the final book is splat in three main successive steps: (i) A 1.5 h interactive session with the researcher and a class of 8-9 year children. They are simply given the general topic of the book few hours before and ask all the questions they have on it and get some answers; (ii) The researcher writes a book in which all the questions raised by children are answered (at least partially). The scientific elements should be inserted in a lively story with few characters. The story should be more than a simple dialogue; a genuine fiction should take place and come first so that children do not even notice they are understanding and learning; (iii) Once children have read the book, there is a second session to get some feedback and possibly edit the manuscript (altering a character, adding some explanations...). After the book is illustrated and published. People involved in these popularization activities will share their feedback.

This paper takes as its starting point the concepts that make up the process of institutionalization of a field of knowledge in the following phases: 1. Differentiation of subjects, methods and techniques of knowledge or existing disciplines, 2. The subject previously considered as peripheral is now seem as part of a particular field of knowledge, 3. The new field becomes significant in the set of an area and starts the standardization of recruitment of human resources, selection of experts and financial resources, and 4. Consolidation of the new field, building its culture within the scientific community, with its social networks of communication, scientific associations and its own publications. Our central objective is to analyze the role of the Ciência e Saúde Coletiva Journal in the process of institutionalization of the Collective Health; we situate the Collective Health and its stages, make a brief report on the history of scientific publications by emphasizing the Brazilian studies on the public health field, and work the early stages of the Journal.

An effective approach to introduce 2YC students to ocean science research is through propagating inquiry-based experiences into existing geosciences courses using a series of research activities. The proposed activity is based on scientific ocean drilling, where students begin their research experience (pre-field activity) by reading articles from scientific journals and analyzing and interpreting core and log data on a specific research topic. At the end of the pre-field activity, students will visit the Gulf Coast Repository to examine actual cores, smear slides, thin sections etc. After the visit, students will integrate findings from their pre-field and field activities to produce a term paper. These simple activities allow students to experience in the iterative process of scientific research, illuminates how scientists approach ocean science, and can be the hook to get students interested in pursuing ocean science as a career.
The citation merit of scientific publications.
Crespo, Juan A; Ortuño-Ortín, Ignacio; Ruiz-Castillo, Javier
2012-01-01
We propose a new method to assess the merit of any set of scientific papers in a given field based on the citations they receive. Given a field and a citation impact indicator, such as the mean citation or the [Formula: see text]-index, the merit of a given set of [Formula: see text] articles is identified with the probability that a randomly drawn set of [Formula: see text] articles from a given pool of articles in that field has a lower citation impact according to the indicator in question. The method allows for comparisons between sets of articles of different sizes and fields. Using a dataset acquired from Thomson Scientific that contains the articles published in the periodical literature in the period 1998-2007, we show that the novel approach yields rankings of research units different from those obtained by a direct application of the mean citation or the [Formula: see text]-index.

Managing scientific data is probably one the most challenging issues in modern science. In plaeosciences the question is made even more sensitive with the need of preserving and managing high value fragile geological samples: cores. Large international scientific programs, such as IODP or ICDP led intense effort to solve this problem and proposed detailed high standard work- and dataflows thorough core handling and curating. However many paleoscience results derived from small-scale research programs in which data and sample management is too often managed only locally - when it is… In this paper we present a national effort leads in France to develop an integrated system to curate ice and sediment cores. Under the umbrella of the national excellence equipment program CLIMCOR, we launched a reflexion about core curating and the management of associated fieldwork data. Our aim was then to conserve all data from fieldwork in an integrated cyber-environment which will evolve toward laboratory-acquired data storage in a near future. To do so, our demarche was conducted through an intimate relationship with field operators as well laboratory core curators in order to propose user-oriented solutions. The national core curating initiative proposes a single web portal in which all teams can store their fieldwork data. This portal is used as a national hub to attribute IGSNs. For legacy samples, this requires the establishment of a dedicated core list with associated metadata. However, for forthcoming core data, we developed a mobile application to capture technical and scientific data directly on the field. This application is linked with a unique coring-tools library and is adapted to most coring devices (gravity, drilling, percussion etc.) including multiple sections and holes coring operations. Those field data can be uploaded automatically to the national portal, but also referenced through international standards (IGSN and INSPIRE) and displayed in international portals (currently, NOAA's IMLGS). In this paper, we present the architecture of the integrated system, future perspectives and the approach we adopted to reach our goals. We will also present our mobile application through didactic examples.

SSC, formerly known as Swedish Space Corporation, is a Swedish state-owned company working in several different space related fields, including scientific stratospheric balloon launches. Esrange Space Centre (Esrange in short) located in the north of Sweden is the launch facility of SSC, where both sounding rocket launches and stratospheric balloon launches are conducted. At Esrange there are also facilities for satellite communication, including one of the largest civilian satellite data reception stations in the world. Stratospheric balloons have been launched from Esrange since 1974, when the first flights were performed together with the French space agency CNES. These balloon flights have normally flown eastward either only over Sweden or into Finland. Some flights have also had permission to fly into Russia, as far as the Ural Mountains. Normal flight times are from 4 to 12 hours. These eastward flights are conducted during the winter months (September to May). Long duration flights have been flown from ESC since 2005, when NASA flew the BLAST payload from Sweden to north Canada. The prevailing westerly wind pattern is very advantageous for trans-Atlantic flights during summer (late May to late July). The long flight times are very beneficial for astronomical payloads, such as telescopes that need long observation times. In 2013 two such payloads were flown, the first called SUNRISE was a German/US solar telescope, and the other called PoGOLite with a Swedish gamma-ray telescope. In 14 days PoGOLite, which had permission to fly over Russia, made an almost complete circumpolar flight. Typical scientific balloon payload fields include atmospheric research, including research on ozone depletion, astronomical and cosmological research, and research in technical fields such as aerodynamics. University students from all over Europe are involved in flights from Esrange under a Swedish/German programme called BEXUS. Two stratospheric balloons are flown with student payloads yearly, with the goal to introduce students in ballooning. Over the next couple of years the plan is to make a re-flight of the PoGOLite payload, fly two Japanese balloon payloads for planetary science missions, fly four student balloons, three balloons for technical studies of re-entry vehicles, and a balloon with a payload studying aerodynamic behaviour of a falling body.

Since last COSPAR a number of interesting balloon flights have been performed from Esrange. In late 2014 parachute tests for the ExoMars programme was performed by drop-test from balloons. This was followed up on in the summer of 2015 with full end-to-end dynamic stability tests of Earth re-entry capsule shapes. Several balloon-borne UAV tests have been performed in 2015. A small high-altitude gliding UAV was tested in the spring, a large supersonic UAV was flown in the summer, and in the late autumn several tests of a small glider were done. A number of flights of a small Swedish science package have been made in 2015 and 2016, and four flights within the BEXUS student programme have also been performed. Seven scientific flights studying the electron losses from Earth's radiation belt were performed by US scientists in August 2015, with the longest flight lasting more than 36 hours. In summer 2016 there is a plan to make a re-flight of the PoGOLite payload, studying polarized X-rays. The latest results from this will be presented.
Citizen Science is a fast-growing field in which scientific investigations are conducted by volunteers, which have been successful in expanding scientific knowledge, raising environmental awareness, and leveraging change.

The Rain in Cumulus over the Ocean (RICO) project was an intensive field project aimed to study and understand precipitation processes in trade wind cumulus. The project took place from Nov 23, 2004 until Jan 25, 2005 on two small islands of the Lesser Antilles, Antigua and Barbuda, where trade wind cumulus fields frequently occur during suppressed wintertime conditions. RICO provided a unique combination of research and education by offering the RICO Graduate Seminar Series and the development and implementation of a graduate student designed and directed research flight. One of the main goals of the graduate student research flight was to allow graduate students to participate in the process of developing a research flight plan and identifying scientific goals and objectives first-hand. Added benefits included the possibility of addressing scientific questions not included in the main RICO objectives. This also involved collaboration when discussing different ideas and initiatives and the full development of all stages of the research flight including the coordination of two research aircraft (NCAR-C130, University of Wyoming King Air), one research vessel (RV Seward Johnson), S-Pol radar site and real time operations center satellite information. Seventeen graduate students from both the US and Europe developed two different plans to be presented to RICO project principle investigators; both of which were approved. The island tail objective aimed at characterizing the line of clouds known as 'island tails' that frequently form off the leeward coast of the Caribbean islands. This objective was successful in its implementation on Jan 18, 2005 with measurements made in vigorous, waterspout producing tail clouds immediately downwind of Barbuda. The investigation of these 'tails' fills a void in current cloud physics research since it is the first time this ubiquitous feature of trade-wind islands has been the focus of careful study. Scientific questions to be addressed with data collected on the island tail include: 1) Are these clouds forced by a heated island effect or another dynamical mechanism? 2) Do islands serve merely as source regions of aerosol which act as nucleation sites? 3) Where in the island tail does rain develop, if at all? A description of the unique learning experience and the educational and scientific benefits of the graduate student research flight island tail objective are outlined and discussed.

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 in the Connecting Arctic/Antarctic Researcher and Educators (CARE) Network. CARE, established to help foster ongoing discussions about science content and educational approaches, uses a combination of conference calls and online interactive software for document sharing and discussion. Teacher and researchers pairs are also encouraged to continue developing their collaborative partnership on an individual basis. This presentation will provide an overview of TREC with co-presentations by a TREC teacher and researcher. The presentation highlights the effectiveness and value of pairing virtual learning with real-time research experiences.

2012-07-01
ESO's Multi-conjugate Adaptive-optics Demonstrator (MAD) was a prototype designed and built to demonstrate wide-field adaptive optics science on large telescopes. The outstanding results obtained during commissioning and guaranteed time observations (GTO) prompted ESO to issue and open call to the community for 23 science demonstration (SD) observing nights distributed in three runs (in order to provide access to the summer an winter skies). Thus, in total MAD was used for science for 33 nights including the 10 nights of GTO time. date, 19 articles in refereed journals (including one in Nature) have been published based fully or partially o MAD data. To the best of our knowledge, these are not only the first, but also the only scientific publication from MCAO instruments world-wide to date (at least in Astronomy). The scientific impact of these publication, as measured by the h-index, is comparable to that of other AO instruments on the VLT, although over the years these instruments have been allocated many more nights than MAD. In this contribution we present an overview of the scientific results from MAD and a more detailed discussion of the most cited papers.
The ICDP Information Network and the Chinese Continental Scientific Drilling CCSD
NASA Astrophysics Data System (ADS)
Conze, R.; Su, D.
2002-12-01
ICDP is an international program investigating the 'System Earth' in multidisciplinary co-operation. Funded drilling projects are characterized by detailed fieldwork at world-class geological sites on the continents and by the global scope of research objectives. During project work, partnering researchers from all over the world work together at remote drill sites and in laboratories at their institutions. Researchers apply a range of highly diverse scientific methodologies, thereby acquiring huge data sets. Multinational co-operation and increasing amounts of scientific data require completely new concepts and practices for scientific work, and place heavy demands on information and communications management. This is achieved by means of the ICDP Information Network. Scientists working on ICDP related data need a central long-term data archive with powerful tools for navigation, data modeling and analysis. The Chinese Continental Scientific Drilling CCSD is a national key scientific and engineering project of the PR China supported by ICDP. The current drill site of CCSD is located in Donghai, Jiangsu Province, the eastern part of the Dabie-Sulu UHP metamorphic belt, which possesses global geological significance. From the spud on June 25, 2001 to April 6, 2002, the 2000m pilot hole was finished with a total core recovery of 88.7% and an average inclination angle of 3-4 degrees. The pilot hole has been transformed to the main hole by hole opening. Deepening and coring of the CCSD-1 main hole is currently in progress. Most of the basic scientific documentation and measurements are done in a large field laboratory directly beside the drill rig, which was set up using the standard of the former German Continental Scientific Drilling (KTB). It includes a powerful infrastructure for computing and electronic communication as well as a comprehensive twofold data and information management: 1. The CCSD-DMIS is a special Data Management Information System for the chinese project management, which is used for internal controlling and decision making. 2. The CCSD-DIS is the specifically designed on-site Drilling Information System, which is used for documentation and archiving of all kinds of scientific and technical information. Both are used in a local Intranet within the field lab, but they also provide certain information via secured Internet services. The CCSD-DIS feeds day-by-day the current reports and new recordings to the CCSD Web portal within the ICDP Information Network (http://www.icdp-online.org/html/sites/donghai/news/news.html). This portal provides chinese and english news and information for the public as well as scientific and technical stuff which is only available for the international CCSD Science Team. Using the example of the CCSD project, a poster and an on-line presentation will show the main components and value-added services of the ICDP Information Network like: ú the common portal for and dissemination of project information by the ICDP Clearinghouse, ú capture of scientific drilling data using individual On-Site Drilling Information Systems (DIS), ú virtual global field laboratories based on eXtended DIS, ú integrated evaluation and analysis of data supported by the ICDP Data Webhouse.

To describe the reporting of public health research in Francophone sub-Saharan Africa (FSA). A bibliometric research study of scientific public health publications in FSA, which includes 24 countries and approximately 260 million people. Two researchers analysed original articles published in 2007 in the medical or social sciences fields and indexed in Scopus. At least one co-author of articles had to be based in FSA. The analysis focused on research field, public health function (WHO classification), FSA country author's affiliation, language, journal type and global burden of disease (WHO classification). Of 1047 articles retrieved by the search, 212 were from the public health field. The number of articles per country varied from 0 to 36. Public health functions examined were health service research (24.5%), health monitoring (27.4%), prevention (15%) and legislation (0.5%). The distribution of health needs described in the articles was close to that of the WHO data for Africa for 2004: infectious and parasitic diseases (70% vs 54%), maternal and perinatal conditions (15% vs 17%), non-communicable diseases (15.6% vs 21%), and injuries (0.5% vs 8%). The areas reported in published articles from sub-Saharan Africa reflect the health needs distribution in Africa; however, the number of publications is low, particularly for prevention. In light of the current focus on evidence-based public health, this study questions whether the international scientific community adequately considers the expertise and perspectives of African researchers and professionals.

Objective Researchers use a large number of information technology tools from the beginning until the publication of a scientific study. The aim of the study is to investigate the technology and data processing tool usage preferences of academics who produce scientific publications in the field of anaesthesiology. Methods A multiple-choice survey, including 18 questions regarding the use of technology to assess the preferences of academicians, was performed. Results PubMed has been the most preferred article search portal, and the second is Google Academic. Medscape has become the most preferred medical innovation tracking website. Only 12% of academicians obtain a clinical trial registration number for their randomized clinical research. In total, 28% of respondents used the Consolidated Standards of Reporting Trials checklist in their clinical trials. Of all participants, 21% was using Dropbox and 9% was using Google-Drive for sharing files. Google Chrome was the most preferred internet browser (32.25%) for academic purposes. English language editing service was obtained from the Scribendi (21%) and Textcheck (12%) websites. Half of the academics were getting help from their specialist with a personal relationship, 27% was doing it themselves, and 24% was obtaining professional assistance for statistical requirements. Sixty percent of the participants were not using a reference editing program, and 21% was using EndNote. Nine percent of the academics were spending money for article writing, and the mean cost was 1287 Turkish Liras/year. Conclusion Academics in the field of anaesthesiology significantly benefit from technology and informatics tools to produce scientific publications. PMID:27366448
Scheduling Algorithm for the Large Synoptic Survey Telescope

Ichharam, Jaimal; Stubbs, Christopher
2015-01-01
The Large Synoptic Survey Telescope (LSST) is a wide-field telescope currently under construction and scheduled to be deployed in Chile by 2022 and operate for a ten-year survey. As a ground-based telescope with the largest etendue ever constructed, and the ability to take images approximately once every eighteen seconds, the LSST will be able to capture the entirety of the observable sky every few nights in six different band passes. With these remarkable features, LSST is primed to provide the scientific community with invaluable data in numerous areas of astronomy, including the observation of near-Earth asteroids, the detection of transient optical events such as supernovae, and the study of dark matter and energy through weak gravitational lensing.In order to maximize the utility that LSST will provide toward achieving these scientific objectives, it proves necessary to develop a flexible scheduling algorithm for the telescope which both optimizes its observational efficiency and allows for adjustment based on the evolving needs of the astronomical community.This work defines a merit function that incorporates the urgency of observing a particular field in the sky as a function of time elapsed since last observed, dynamic viewing conditions (in particular transparency and sky brightness), and a measure of scientific interest in the field. The problem of maximizing this merit function, summed across the entire observable sky, is then reduced to a classic variant of the dynamic traveling salesman problem. We introduce a new approximation technique that appears particularly well suited for this situation. We analyze its effectiveness in resolving this problem, obtaining some promising initial results.

In March 2005, four students and three teachers from Boerne High School in Texas accompanied UTIG GK-12 Co-PIs Katherine Ellins and Ian Dalziel, and NSF GK-12 Fellow Ethan Perry to Tierra del Fuego to join an international team of scientists studying the climate-tectonic history recorded in Lago Fagnano, Tierra del Fuego, Argentina. For two weeks, students and teachers engaged in authentic scientific research that included geologic field mapping and reconnaissance, and student/teacher developed water and soils sampling routines. The Lago Fagnano experience enabled: (1) the Boerne High School group to be integrated into an active field research program and to bring tangible experiences, knowledge and high-quality data back to the classroom; (2) participating research scientists to convey the importance of their science to a wider audience; and (3) the NSF GK-12 Fellow to gain valuable experience in communicating the essential scientific knowledge and field skills to high school participants before field deployment. The GK-12 Fellow's bridging role through the course of the project enhanced his scientific understanding of the climate-tectonic setting of Tierra del Fuego, fostered the development of new professional contacts with research scientists and led to a fresh perspective on how research science can be integrated in high school science curriculum. The GK-12 Fellow served as the primary mentor to the K-12 participants and the liaison between UTIG research scientists and the Boerne High School group. The Fellow helped prepare the Boerne group for the field research experience and to design a research project using water and soil analyses to assess chemical and isotopic trends within the lake's watershed. Preparatory activities began three months prior to field deployment and included workshops, classroom visits and teleconferences aimed at teaching field skills (reading and creating geologic maps, compass measurements, GPS, field notebooks) and increasing participants' knowledge of geoscience concepts and regional tectonics. The Fellow blended inquiry- and discussion-based exercises to convey the relevance of the Lago Fagnano research. Interaction between the GK-12 Fellow and Boerne High School participants preceding, during and following the field experience was an important element in the success of this research experience for teachers and their students. This interaction benefited the high school students and teachers because they were able to grasp the fundamental goals of the research experience prior to arriving in the field, thereby ensuring that the time spent in the field was used efficiently to carry out the project. Long-term involvement in the planning, execution and synthesis of the experience provided the high school participants with a sense of ownership of the science conducted on Lago Fagnano. This field initiative represents the first time that both K-12 students and teachers were integrated into a field setting with UTIG research scientists. Such experiences are valuable because they demonstrate the true manner in which science is conducted and advance partnerships between university research institutions and K-12 schools. The level of mentoring that the GK-12 Fellow provided through all stages of the project maximized the potential benefits of such an experience.
National Geographic FieldScope: Tools for Engaging a Range of Audiences in Citizen Science

OConnor, S.; Takaki, E.
2013-12-01
Recognizing the promise of projects that engage non-scientists in scientific research as a context for informal science learning, National Geographic set out in 2009 to develop a technology infrastructure to support public participation in scientific research (PPSR), or citizen science, projects. As a result, NG has developed a web-based platform called FieldScope to host projects in which geographically distributed participants submit local observations or measurements to a shared database. This project is motivated by the observation that historically citizen science initiatives have been siloed using different technologies, and that these projects rarely provide participants with the opportunity to participate in data analysis or any other aspects of the scientific process except for collecting and contributing data. Therefore, FieldScope has been designed to support data visualization and analysis using geospatial technologies and aims to develop social networking tools for communicating and discussing findings. Since educational impact is the project's primary priority, FieldScope is also being designed with usability by novices in mind. In addition to engaging novices in participation in citizen science, the design of the application is also meant to engage students and others in working with geospatial technologies, in this case, web-based GIS. The project's goal is to create a single, powerful infrastructure for PPSR projects that any organization can use to create their own project and support their own community of participants. The FieldScope environment will serve as a hosting environment for PPSR projects following the model of hosted communities of practice that has become widespread on the web. The goal is to make FieldScope a publicly-available resource for any PPSR project on a no- or low-cost basis. It will also make synergies possible between projects that are collecting related data in the same geographic area. NG is now in the fourth year of an NSF grant to bring this vision for FieldScope to life. The project is structured around key collaborations with 'conveners' of existing citizen science initiatives. These existing initiatives include Project BudBurst, the Association of Zoos and Aquariums FrogWatch USA, and the Alice Ferguson Fund's Trash Free Potomac Initiative. These groups are serving as testbed partners, building their citizen science projects with the FieldScope development tools and hosting their communities within the FieldScope infrastructure. Through outcomes research and evaluation, these testbeds will provide much-needed evidence about the value of citizen science for learning and the conditions that can maximize those outcomes. Presenters will share findings to date of the project, including a demonstration of the technology using examples from our convening partners from the NSF project, as well as other communities using FieldScope, ranging from citizen science initiatives in the Yukon River watershed aimed at engaging indigenous Alaskan populations to a wide-spread initiative across the Chesapeake Bay watershed designed for students and environmental education program participants.

The purpose of this qualitative study was to discover the influence of instructional games on middle school learners' use of scientific language, concept understanding, and attitude toward learning science. The rationale for this study stemmed from the lack of research concerning the value of play as an instructional strategy for older learners. Specifically, the study focused on the ways in which 6 average ability 7th grade students demonstrated scientific language and concept use during gameplay. The data were collected for this 6-week study in a southern New Jersey suburban middle school and included audio recordings of the 5 games observed in class, written documents (e.g., student created game questions, self-evaluation forms, pre- and post-assessments, and the final quiz) interviews, and researcher field notes. Data were coded and interpreted borrowing from the framework for scientific literacy developed by Bybee (1997). Based on the findings, the framework was modified to reflect the level of scientific understanding demonstrated by the participants and categorized as: Unacquainted, Nominal, Functional, and Conceptual. Major findings suggested that the participants predominantly achieved the Functional level of scientific literacy (i.e., the ability to adequately and appropriately use scientific language in both written and oral discourse) during games. Further, it was discovered that the participants achieved the Conceptual level of scientific literacy during gameplay. Through games participants were afforded the opportunity to use common, everyday language to explore concepts, promoted through peer collaboration. In games the participants used common language to build understandings that exceeded Nominal or token use of the technical vocabulary and concepts. Additionally, the participants reported through interviews and self-evaluation forms that their attitude (patterns included: Motivation, Interest, Fun, Relief from Boredom, and an Alternate Learning Approach) toward learning science was positively affected by playing games. This research confirmed the value of playing instructional games and indicated the potential benefits for teaching and learning scientific vocabulary and concepts in middle school settings. Educators are in need of finding methods that stimulate the often disinterested or disengaged adolescent student. Results from this investigation suggested that games provided a meaningful alternate learning approach that relieved the boredom associated with traditional science instruction.
Electromagnetic cellular interactions.

Chemical and electrical interaction within and between cells is well established. Just the opposite is true about cellular interactions via other physical fields. The most probable candidate for an other form of cellular interaction is the electromagnetic field. We review theories and experiments on how cells can generate and detect electromagnetic fields generally, and if the cell-generated electromagnetic field can mediate cellular interactions. We do not limit here ourselves to specialized electro-excitable cells. Rather we describe physical processes that are of a more general nature and probably present in almost every type of living cell. The spectral range included is broad; from kHz to the visible part of the electromagnetic spectrum. We show that there is a rather large number of theories on how cells can generate and detect electromagnetic fields and discuss experimental evidence on electromagnetic cellular interactions in the modern scientific literature. Although small, it is continuously accumulating. Copyright © 2010 Elsevier Ltd. All rights reserved.

The situation of Research in radiology in Spain is analysed by examining the number of publications by Spanish authors in main stream international journals. The scientific production of Spanish researchers in journals included in the Science Citation Index (SCI) under the headings "Radiology, Nuclear Medicine, and Medical Imaging" and "Neuroimaging" during the years 1996-2003. During this period the scientific production in these fields comprised 1,562 documents (3.5% of the total production for Spanish clinical medicine); scientific production in these fields increased by 40% in this period in comparison to 24% for all clinical medicine. The bulk of the production was concentrated in the autonomous communities of Catalonia (35%), Madrid (28%), and Valencia (10%). The autonomous communities of Navarra and Cantabria had a high relative production after the results were adjusted for population. The healthcare sector is the most active, with the Hospital de la Santa Creu i Sant Pau, the Hospital Clinic de Barcelona, and the Hospital Vall d'Hebron being outstanding in that they not only lead the country in the number of publications but also publish more in journals with high impact factors. Among centers other than hospitals, the Center for Research in Energy, the Environment, and Technologies (CIEMAT) and the Medical School of the Universidad Complutense de Madrid are the most important. A high degree of collaboration is evident: 68% of the documents were produced by more than one institution, foreign centers were involved in 20%, and the documents were signed by an average of six authors. Conclusions. In summary, the data show that Spanish radiological research is becomin increasingly international, although this process is still in the initial stage, with the percentage of documents published in the most prestigious journals for this specialty being lower than in other disciplines. The relative activity and production of Spain is slightly below the average of the European Union, but the country shows a rising trend for both production and impact.

In contrast to other areas of medical practice, there was a lack of a clear, concise and accessible synthesis of scientific literature to aid the recognition and investigation of suspected child abuse, and no national training program or evidence based guidelines for clinicians. The project's aim was to identify the current scientific evidence for the recognition and investigation of suspected child abuse and neglect and to disseminate and introduce this into clinical practice. Since 2003 a comprehensive program of Systematic Reviews of all aspects of physical abuse, emotional abuse, and neglect of children, has been developed. Based on NHS Centre for Reviews and Dissemination standards, methodology was devised and reviewers trained. Dissemination was via peer reviewed publications, a series of leaflets highlighting key points in a Question and Answer format, and a website. To date, 21 systematic reviews have been completed, generating 28 peer reviewed publications, and six leaflets around each theme (eg fractures, bruising). More than 250,000 have been distributed to date. Our website generates more than 10,000 hits monthly. It hosts primary reviews that are updated annually, links to all included studies, publications, and detailed methodology. The reviews have directly informed five national clinical guidelines, and the first evidence based training in Child Maltreatment. Child abuse is every health practitioner's responsibility, and it is vital that the decisions made are evidence based, as it is expected in all other fields of medicine. Although challenging, this project demonstrates that it is possible to conduct high quality systematic reviews in this field. For the first time a clear concise synthesis of up to date scientific evidence is available to all practitioners in a range of accessible formats. This has underpinned high quality national guidance and training programs. It ensures all professionals have the appropriate knowledge base in this difficult and challenging field. PMID:26734183

A Clockwork Wikipedia: From a Broad Perspective to a Case Study.
Benjakob, Omer; Aviram, Rona
2018-06-01
While research has shown that scientists use Wikipedia and that scientific content on Wikipedia ramifies back into scientific literature, many questions remain on how the two sides interact and through what paradigm this dynamic may be best understood. Using the circadian clock field as a case study, we discuss this scientific field's representation on Wikipedia. We traced the changes made to the articles for "Circadian clock" and "Circadian rhythm" and reviewed the debates that informed them over a span of a decade, using Wikipedia's native and third-party tools. Specifically, we focused on how groundbreaking research pertaining to the function of biological oscillators was integrated into the articles to reflect a wider paradigmatic shift within the field. We also identified the articles' main editors to detail the dynamic collective editorial process that took place during a time that saw the field undergo a fundamental change. We discuss the different concerns the academic community has with Wikipedia-specifically regarding its content and its contributors-to ask whether the online encyclopedia's open model is inherently at odds with scientific culture or whether the model could reflect science or even expand on its core values and practices such as peer review and the idea of communicating science.

Despite decades of effort, the 5-year overall survival rate of pancreatic cancer (PC) remains at only approximately 5%. Until now, no detailed knowledge regarding the worldwide research architecture of PC has yet been established. Hence, we conducted this scientometric analysis to quantify the global research activity in this field. The total research productivity was screened and research output of countries, categories, individual institutions, authors, and their collaborative networks were analyzed by the new quality and quantity indices in science platform. Results were visualized via state-of-the-art density equalizing mapping projections. The results indicated that Japan, Germany, and the United States played a leading role regarding output activity, multilateral, and bilateral cooperations. Within the past decades, the topic PC has developed into a scientific field covering many subject areas. Recently published studies predict that the scientific progress will be mainly depending on international cooperations; we can confirm that development by now. We conclude that the field of PC is constantly progressing in which the influence of international cooperations on the scientific progress is of increasing importance. Nevertheless, research in the field of PC still needs to be strengthened to reduce morbidity and mortality in the future.

GREENLAND—Tom Lane and Suk Joon Lee, recent graduates of Dartmouth University's Thayer School of Engineering, in Hanover, N. H., are standing outside in the frigid cold testing an autonomous robot that could help with scientific research and logistics in harsh polar environments. This summer, Lane, Lee, and others are at Summit Station, a U.S. National Science Foundation (NSF)-sponsored scientific research station in Greenland, fine-tuning a battery-powered Yeti robot as part of a team working on the NSF-funded Cool Robot project. The station, also known as Summit Camp, is located on the highest point of the Greenland Ice Sheet (72°N, 38°W, 3200 meters above sea level) near the middle of the island. It is a proving ground this season for putting the approximately 68-kilogram, 1-cubic-meter robot through its paces, including improving Yeti's mobility capabilities and field-testing the robot. (See the electronic supplement to this Eos issue for a video of Yeti in action (http://www.agu.org/eos_elec/).) During field-testing, plans call for the robot to collect data on elevation and snow surface characteristics, including accumulation. In addition, the robot will collect black carbon and elemental carbon particulate matter air samples around Summit Camp's power generator to help study carbon dispersion over snow.
When can scientific studies promote consensus among conflicting stakeholders?
Small, Mitchell J; Güvenç, Ümit; DeKay, Michael L
2014-11-01
While scientific studies may help conflicting stakeholders come to agreement on a best management option or policy, often they do not. We review the factors affecting trust in the efficacy and objectivity of scientific studies in an analytical-deliberative process where conflict is present, and show how they may be incorporated in an extension to the traditional Bayesian decision model. The extended framework considers stakeholders who differ in their prior beliefs regarding the probability of possible outcomes (in particular, whether a proposed technology is hazardous), differ in their valuations of these outcomes, and differ in their assessment of the ability of a proposed study to resolve the uncertainty in the outcomes and their hazards--as measured by their perceived false positive and false negative rates for the study. The Bayesian model predicts stakeholder-specific preposterior probabilities of consensus, as well as pathways for increasing these probabilities, providing important insights into the value of scientific information in an analytic-deliberative decision process where agreement is sought. It also helps to identify the interactions among perceived risk and benefit allocations, scientific beliefs, and trust in proposed scientific studies when determining whether a consensus can be achieved. The article provides examples to illustrate the method, including an adaptation of a recent decision analysis for managing the health risks of electromagnetic fields from high voltage transmission lines. © 2014 Society for Risk Analysis.
Balance in scientific impact assessment: the EGU Awards Committe experience

2016-04-01
Evaluation of scientific impact is becoming an essential step all over the world for assigning academic positions, funding and recognition. Impact is generally assessed by means of objective bibliometric indicators which are frequently integrated with a subjective evaluation by one or more individuals. An essential requirement of impact assessment is to ensure balance across several potential discriminating factors, including gender, ethnics, culture, scientific field and many others. Scientific associations need to ensure balance in any step of their activity and in particular when electing their representatives, evaluating scientific contributions, reviewing papers and assigning awards. While ensuring balance is a strict necessity, how to get to target is still a matter of vivid debates. In fact, the context of science is very different with respect to the general context of society and the need for scientific associations to maintain confidentiality in their evaluation procedures makes the application of transparent procedures more complicated. This talk aims to present the experience and the efforts of the European Geosciences Union to ensure balance, with a particular focus on gender balance. Data and statistics will be presented in the attempt to provide constructive indications to get to the target of giving equal opportunities to researchers across gender, continents and ethnic groups. Science is a unifying discipline and balance will be vital to ensure that humans and our planet co-evolve sustainably.

Polymer microcapsules are of particular interest for applications including self-healing coatings, catalysis, bioreactions, sensing, and drug delivery. The primary way that polymer capsules can exhibit functionality relevant to these diverse fields is through the incorporation of functional cargo in the capsule cavity or wall. Diverse functional and therapeutic cargo can be loaded into polymer capsules with ease using polymer-stabilized calcium carbonate (CaCO 3 ) particles. A variety of examples are demonstrated, including 15 types of cargo, yielding a toolbox with effectively 500+ variations. This process uses no harsh reagents and can take less than 30 min to prepare, load, coat, and form the hollow capsules. For these reasons, it is expected that the technique will play a crucial role across scientific studies in numerous fields.

The Andean Amazon River Analysis and Management project, an IAI Collaborative Research Network operating during 1999-2004, examined the impacts of climate and land-use changes on the hydrobiogeochemistry of rivers draining the Amazon Andes of Ecuador, Peru, Colombia and Bolivia. The project also provided a means to strengthen scientific collaboration among these Andean countries and the USA. Research in these countries was carried out under the guidance of investigators with backgrounds in the relevant environmental fields, but the bulk of the research activities were carried out by undergraduate and graduate students who studied within these countries and overseas. Twenty graduate students and 15 undergraduates completed studies within the project, in topics related to monitoring hydrometeorological variables both in time and space. Student research and capacity building were focused in areas central to global environmental change, including modeling of precipitation and precipitation-runoff processes, basin-scale water quality characterization and biogeochemical cycling, and socioeconomic controls on the use and management of riverine resources. The analysis of human dimension aspects of climate change research was also featured, especially those aspects that linked the consequences of water quality degradation on human health. Most of undergraduate and graduate students that collaborated in the AARAM project have joined national environmental institutions and some have continued for higher scientific degrees in fields closely related to the IAI scientific agenda. Through this IAI initiative, the number of trained global change scientists in the Andean countries has grown and there is enhanced awareness of key global change science issues among the scientific community.

The study aimed to analyze publications in the field of "pediatric tuberculosis" and associate them with regional Tuberculosis (TB) profile. A schematic analysis of scientific production in the field of pediatric tuberculosis between 1990 and 2010 using ISI web of science was carried out. Terms used for searches were each as a combination of "Mycobacterium Tuberculosis", or "Tuberculos*" and "Child", or "Infant", or "New born", or "Neonatal", or "Adolescent", or "Pediatric". Features including year of publication, citation per year, country of origin, funding state, contributing university, language, leading journals and authors, and highly cited articles, main journal publishing these articles were taken into account. The search retrieved 3417 articles (of 4559 total) with an almost gradual annually progressive pattern from 20 (in 1990) to 302 (in 2009) which have been cited totally 48459 times and 14.18 times per article. The greatest contribution originated from United States of America (25.11%) followed by South Africa (12.17%), and England (11.18%). Interestingly, 82.4% of all South African articles were from Stellenbosch University and Cape Town University on contrary. International Journal of Tuberculosis and Lung Disease ranked as the first with regard to the number of articles and Lancet with regard to the number of highly cited articles. Developing countries excluding South Africa despite their high prevalence scarcely contribute to the field and USA is the leading country in the field.

The NASA Lewis Research Center recently codeveloped a state-of-the-art x-ray CT facility (designated SMS SMARTSCAN model 100-112 CITA by Scientific Measurement Systems, Inc., Austin, Texas). This multipurpose, modularized, digital x-ray facility includes an imaging system for digital radiography, CT, and computed laminography. The system consists of a 160-kV microfocus x-ray source, a solid-state charge-coupled device (CCD) area detector, a five-axis object-positioning subassembly, and a Sun SPARCstation-based computer system that controls data acquisition and image processing. The x-ray source provides a beam spot size down to 3 microns. The area detector system consists of a 50- by 50- by 3-mm-thick terbium-doped glass fiber-optic scintillation screen, a right-angle mirror, and a scientific-grade, digital CCD camera with a resolution of 1000 by 1018 pixels and 10-bit digitization at ambient cooling. The digital output is recorded with a high-speed, 16-bit frame grabber that allows data to be binned. The detector can be configured to provide a small field-of-view, approximately 45 by 45 mm in cross section, or a larger field-of-view, approximately 60 by 60 mm in cross section. Whenever the highest spatial resolution is desired, the small field-of-view is used, and for larger samples with some reduction in spatial resolution, the larger field-of-view is used.
The money trail: a new historiography for networks, patronage, and scientific careers.
Andersen, Casper; Bek-Thomsen, Jakob; Kjoergaard, Peter C
2012-06-01
Money is everywhere in science. Yet historians have only rarely placed the money trail at the center of their analyses. The essays in this Focus section demonstrate that following the money offers a historiographical path for investigating a number of key issues across disciplinary boundaries in the nineteenth and twentieth centuries. Drawing on cases and materials relating to a number of scientific fields, including electrical engineering, aeronautics, agriculture, and paleontology, the essays examine the continuous role of money in industrial and military patronage, personal connections and networks, and spatial and geographical dimensions of science, as well as in relation to state funding and ownership. Together, the contributions demonstrate how following the money offers a way of overcoming hyperprofessionalism in the history of science.

The Space Telescope (ST) represents a new concept regarding spaceborne astronomical observatories. Maintenance crews will be brought to the orbital worksite to make repairs and replace scientific instruments. For major overhauls the telescope can be temporarily returned to earth with the aid of the Shuttle. It will, thus, be possible to conduct astronomical studies with the ST for two decades or more. The five first-generation scientific instruments used with the ST include a wide field/planetary camera, a faint object camera, a faint object spectrograph, a high resolution spectrograph, and a high speed photometer. Attention is given to the optical telescope assembly, the support systems module, aspects of mission and science operations, unscheduled maintenance, contingency orbital maintenance, planned on-orbit maintenance, ground maintenance, ground refurbishment, and ground logistics.

In a scientific laboratory setting, standard equipment such as cryocoolers are often used as part of a custom sample environment system designed to regulate temperature over a wide range. The end user may be more concerned with precise sample temperature control than with base temperature. But cryogenic systems tend to be specified mainly in terms of cooling capacity and base temperature. Technical staff at scientific user facilities (and perhaps elsewhere) often wonder how to best specify and evaluate temperature control capabilities. Here we describe test methods and give results obtained at a user facility that operates a large sample environmentmore » inventory. Although this inventory includes a wide variety of temperature, pressure, and magnetic field devices, the present work focuses on cryocooler-based systems.« less

Secreted membrane-enclosed vesicles, collectively called extracellular vesicles (EVs), which include exosomes, ectosomes, microvesicles, microparticles, apoptotic bodies and other EV subsets, encompass a very rapidly growing scientific field in biology and medicine. Importantly, it is currently technically challenging to obtain a totally pure EV fraction free from non-vesicular components for functional studies, and therefore there is a need to establish guidelines for analyses of these vesicles and reporting of scientific studies on EV biology. Here, the International Society for Extracellular Vesicles (ISEV) provides researchers with a minimal set of biochemical, biophysical and functional standards that should be used to attribute any specific biological cargo or functions to EVs.

In situ testing, monitoring, and associated laboratory studies are conducted to directly assess and evaluate the waste emplacement environment and the natural barriers to radionuclide transport at Yucca Mountain. This scientific analysis report supports and provides data to UZ flow and transport model reports, which in turn contribute to the Total System Performance Assessment (TSPA) of Yucca Mountain, an important document for the license applicationmore » (LA). The objectives of ambient field-testing activities are described in Section 1.1. This report is the third revision (REV 03), which supercedes REV 02. The scientific analysis of data for inputs to model calibration and validation as documented in REV 02 were developed in accordance with the Technical Work Plan (TWP) ''Technical Work Plan for: Performance Assessment Unsaturated Zone'' (BSC 2004 [DIRS 167969]). This revision was developed in accordance with the ''Technical Work Plan for: Unsaturated Zone Flow Analysis and Model Report Integration'' (BSC 2004 [DIRS 169654], Section 1.2.4) for better integrated, consistent, transparent, traceable, and more complete documentation in this scientific analysis report and associated UZ flow and transport model reports. No additional testing or analyses were performed as part of this revision. The list of relevant acceptance criteria is provided by ''Technical Work Plan for: Unsaturated Zone Flow Analysis and Model Report Integration'' (BSC 2004 [DIRS 169654]), Table 3-1. Additional deviations from the TWP regarding the features, events, and processes (FEPs) list are discussed in Section 1.3. Documentation in this report includes descriptions of how, and under what conditions, the tests were conducted. The descriptions and analyses provide data useful for refining and confirming the understanding of flow, drift seepage, and transport processes in the UZ. The UZ testing activities included measurement of permeability distribution, quantification of the seepage of water into the drifts, evaluation of fracture-matrix interaction, study of flow along faults, testing of flow and transport between drifts, characterization of hydrologic heterogeneity along drifts, estimation of drying effects on the rock surrounding the drifts due to ventilation, monitoring of moisture conditions in open and sealed drifts, and determination of the degree of minimum construction water migration below drift. These field tests were conducted in two underground drifts at Yucca Mountain, the Exploratory Studies Facility (ESF) drift, and the cross-drift for Enhanced Characterization of the Repository Block (ECRB), as described in Section 1.2. Samples collected in boreholes and underground drifts have been used for additional hydrochemical and isotopic analyses for additional understanding of the UZ setting. The UZ transport tests conducted at the nearby Busted Butte site (see Figure 1-4) are also described in this scientific analysis report.« less

Bode, Benjamin; Dennis, Mark
Three-dimensional field configurations where a privileged defect line is knotted or linked have experienced an upsurge in interest, with examples including fluid mechanics, quantum wavefunctions, optics, liquid crystals and skyrmions. We describe a constructive algorithm to write down complex scalar functions of three-dimensional real space with knotted nodal lines, using trigonometric parametrizations of braids. The construction is most natural for the family of lemniscate knots which generalizes the torus knot and figure-8 knot, but generalizes to any knot or link. The specific forms of these functions allow various topological quantities associated with the field to be chosen, such as the helicity of a knotted flow field. We will describe some applications to physical systems such as those listed above. This work was supported by the Leverhulme Trust Programme Grant ''Scientific Properties of Complex Knots''.

Present the method used to elaborate and formalize current scientific knowledge to provide physicians with tools available on the Internet, that enable them to evaluate individual patient risk, give personalized preventive recommendations or early screening measures. The approach suggested in this article is in line with medical procedures based on levels of evidence (Evidence-based Medicine). A cyclical process for developing recommendations allows us to quickly incorporate current scientific information. At each phase, the analysis is reevaluated by experts in the field collaborating on the project. The information is formalized through the use of levels of evidence and grades of recommendations. GLIF model is used to implement recommendations for clinical practice guidelines. The most current scientific evidence incorporated in a cyclical process includes several steps: critical analysis according to the Evidence-based Medicine method; identification of predictive factors; setting-up risk levels; identification of prevention measures; elaboration of personalized recommendation. The information technology implementation of the clinical practice guideline enables physicians to quickly obtain personalized information for their patients. Cases of colorectal prevention illustrate our approach. Integration of current scientific knowledge is an important process. The delay between the moment new information arrives and the moment the practitioner applies it, is thus reduced.
Methodological Problems of Nanotechnoscience

Gorokhov, V. G.
Recently, we have reported on the definitions of nanotechnology as a new type of NanoTechnoScience and on the nanotheory as a cluster of the different natural and engineering theories. Nanotechnology is not only a new type of scientific-engineering discipline, but it evolves also in a “nonclassical” way. Nanoontology or nano scientific world view has a function of the methodological orientation for the choice the theoretical means and methods toward a solution to the scientific and engineering problems. This allows to change from one explanation and scientific world view to another without any problems. Thus, nanotechnology is both a field of scientific knowledge and a sphere of engineering activity, in other words, NanoTechnoScience is similar to Systems Engineering as the analysis and design of large-scale, complex, man/machine systems but micro- and nanosystems. Nano systems engineering as well as Macro systems engineering includes not only systems design but also complex research. Design orientation has influence on the change of the priorities in the complex research and of the relation to the knowledge, not only to “the knowledge about something”, but also to the knowledge as the means of activity: from the beginning control and restructuring of matter at the nano-scale is a necessary element of nanoscience.

Objective: To update of the scientific community about the biomedical engineering involvement in the implantable devices chain. Moreover the transcatheter Aortic Valve (TAV) replacement, in the field of cardiac surgery, will be analyzed as an example of contemporary implantable technology. Methods: A detailed literature review regarding biomedical engineers participating in the implantable medical product chain, starting from the design of the product till the final implantation technique. Results: The scientific role of biomedical engineers has clearly been established. Certain parts of the product chain are implemented almost exclusively by experienced biomedical engineers such as the transcatheter aortic valve device. The successful professional should have a multidisciplinary knowledge, including medicine, in order to pursue the challenges for such intuitive technology. This clearly indicates that biomedical engineers are among the most appropriate scientists to accomplish such tasks. Conclusions: The biomedical engineering involvement in medical implantable devices has been widely accepted by the scientific community, worldwide. Its important contribution, starting from the design and extended to the development, clinical trials, scientific support, education of other scientists (surgeons, cardiologists, technicians etc.), and even to sales, makes biomedical engineers a valuable player in the scientific arena. Notably, the sector of implantable devices is constantly raising, as emerging technologies continuously set up new targets.

The nature of performing a scientific research is a process that has several different components which consist of identifying the key research question(s), choices of scientific approach for the study and data collection, data analysis, and finally reporting on results. Generally, peer review is a series of procedures in the evaluation of a creative work or performance by other people, who work in the same or related field, with the aim of maintaining and improving the quality of work or performance in that field. The assessment of the achievement of every scientist, and thus indirectly determining his reputation in the scientific community of these publications, especially journals, is done through the so-called impact factor index. The impact factor predicts or estimates that how many annual citations article may receive after its publication. Evaluation of scientific productivity and assessment of the published articles of researchers and scientists can be made through the so-called H-index. The quality of published results of scientific work largely depends on knowledge sources that are used in the preparation, which means that it should be considered to serve the purpose and the very relevance of the information used. Scientometrics as a field of science covers all aforementioned issues, and scientometric analysis is obligatory for quality assessment of the scientific validity of published articles and other type of publications.

The assessment of the achievement of every scientist, and thus indirectly determining his reputation in the scientific community of these publications, especially journals, is done through the so-called impact factor index. The impact factor predicts or estimates that how many annual citations article may receive after its publication. Evaluation of scientific productivity and assessment of the published articles of researchers and scientists can be made through the so-called H-index. The quality of published results of scientific work largely depends on knowledge sources that are used in the preparation, which means that it should be considered to serve the purpose and the very relevance of the information used. Scientometrics as a field of science covers all aforementioned issues, and scientometric analysis is obligatory for quality assessment of the scientific validity of published articles and other type of publications.

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.

Reproducibility represents how closely the results of independent tests agree when undertaken using the same materials but different conditions of measurement, such as operator, equipment or laboratory. The concept of reproducibility is fundamental to the scientific method as it prevents the persistence of incorrect or biased results. Yet currently the production of scientific knowledge emphasizes rapid publication of previously unreported findings, a culture that has emerged from pressures related to hiring, publication criteria and funding requirements. Awareness and critique of the disconnect between how scientific research should be undertaken, and how it actually is conducted, has been prominent in biomedicine for over a decade, with the fields of economics and psychology more recently joining the conversation. The purpose of this presentation is to stimulate the conversation in earth sciences where, despite implicit evidence in widely accepted classifications, formal testing of reproducibility is rare.As a formal test of reproducibility, two sets of experiments were undertaken with the same experimental procedure, at the same scale, but in different laboratories. Using narrow, steep flumes and spherical glass beads, grain size sorting was examined by introducing fine sediment of varying size and quantity into a mobile coarse bed. The general setup was identical, including flume width and slope; however, there were some variations in the materials, construction and lab environment. Comparison of the results includes examination of the infiltration profiles, sediment mobility and transport characteristics. The physical phenomena were qualitatively reproduced but not quantitatively replicated. Reproduction of results encourages more robust research and reporting, and facilitates exploration of possible variations in data in various specific contexts. Following the lead of other fields, testing of reproducibility can be incentivized through changes to journal requirements, grant application criteria, funding, collaborative efforts, availability of data, and positive attitudes toward negative results or failed replication attempts.

Methods based on phase-transition-induced pattern formation (PTPF) are increasingly used in medical research. Frequent application fields are medical diagnosis and basic research in homeopathy. Here, we present a systematic review of experimental studies concerning PTPF-based methods applied to homeopathy research. We also aimed at categorizing the PTPF methods included in this review. Experimental studies were collected from scientific databases (PubMed, Web of Science, Russian eLibrary) and from experts in the research field in question, following the PRISMA guidelines. The studies were rated according to pre-defined scientific criteria. The review included 15 experimental studies. We identified seven different PTPF methods applied in 12 experimental models. Among these methods, phase-transition was triggered through evaporation, freezing, or solution, and in most cases led to the formation of crystals. First experimental studies concerning the application of PTPF methods in homeopathic research were performed in the first half of the 20th century; however, they were not continued in the following years. Only in the last decade, different research groups re-launched the idea, introducing new experimental approaches and computerized pattern evaluation techniques. The here-identified PTPF methods are for the first time proposed to be classified as one group of methods based on the same basic physical phenomenon. Although the number of experimental studies in the area is still rather limited, the long tradition in the application of PTPF methods and the dynamics of the present developments point out the high potential of these methods and indicate that they might meet the demand for scientific methods to study potentized preparations.

Major Challenges for the Modern Chemistry in Particular and Science in General.
Uskokovíc, Vuk
2010-11-01
In the past few hundred years, science has exerted an enormous influence on the way the world appears to human observers. Despite phenomenal accomplishments of science, science nowadays faces numerous challenges that threaten its continued success. As scientific inventions become embedded within human societies, the challenges are further multiplied. In this critical review, some of the critical challenges for the field of modern chemistry are discussed, including: (a) interlinking theoretical knowledge and experimental approaches; (b) implementing the principles of sustainability at the roots of the chemical design; (c) defining science from a philosophical perspective that acknowledges both pragmatic and realistic aspects thereof; (d) instigating interdisciplinary research; (e) learning to recognize and appreciate the aesthetic aspects of scientific knowledge and methodology, and promote truly inspiring education in chemistry. In the conclusion, I recapitulate that the evolution of human knowledge inherently depends upon our ability to adopt creative problem-solving attitudes, and that challenges will always be present within the scope of scientific interests.

Research projects now rely on an array of different channels to increase impact, including high-level scientific output, tools, and equipment, but also communication, outreach, and educational activities. This paper focuses on education for children aged 5-12 years and presents activities that aim to help them (and their teachers) grasp some of the complex underlying issues in environmental science. More generally, it helps children to become familiarized with science and scientists, with the aim to enhance scientific culture and promote careers in this field. The activities developed are focused on rainfall: (a) designing and using a disdrometer to observe the variety of drop sizes; (b) careful recording of successive dry and rainy days and reproducing patterns using a simple model based on fractal random multiplicative cascades; and (c) collaboratively writing a children's book about rainfall. These activities are discussed in the context of current state-of-the-art pedagogical practices and goals set by project funders, especially in a European Union framework.

Reiki is used by a growing number of people but little is known about the scientific basis for its use. The Touchstone Process was developed as an ongoing process to systematically analyze published, peer-reviewed studies of Reiki, the results being made accessible to the public online. Thirteen scientifically qualified experts in the field of Reiki were assembled into 3 teams to retrieve, evaluate, and summarize articles using standardized, piloted evaluation forms. Summaries of 26 Reiki articles, including strengths and weaknesses, were posted on a newly developed Web site (www.centerforreikiresearch.org), together with an overall summary of the status of Reiki research and guidelines for future research: The Touchstone Process determined that only 12 articles were based on a robust experimental design and utilized well-established outcome parameters. Of these articles, 2 provided no support, 5 provided some support, and 5 demonstrated strong evidence for the use of Reiki as a healing modality. There is a need for further high-quality studies in this area.

Within the three-semester optional course Science we have also included into curricula the subject entitled Science Practicum consisting of laboratory exercises of complementary natural scientific disciplines whose content exceeds the boundaries of relevant a scientific discipline (physics, biology, …). The paper presents the structure and selected samples of laboratory exercises of physical part of Science Practicum in which we have processed in an integrated way the knowledge of physics and biology at secondary grammar school. When planning the exercises we have proceeded from those areas of mentioned disciplines in which we can appropriately apply integration of knowledge and where the measurement methods are used. We have focused on the integration of knowledge in the field of human sensory organs (eye, ear), dolphins, bats (spatial orientation) and bees (ommatidium of faceted eye) and their modelling. Laboratory exercises are designed in such a way that they would motivate future teachers of natural scientific subjects to work independently with specialized literature of the mentioned natural sciences and ICT.
