Textbooks have a low status in the history of science because they have been seen as mere repositories for scientific knowledge. But historians have recently shown how they play a number of roles that can illuminate different aspects of the history of science, from priority disputes to pedagogical practices. The essays in this Focus section aim to expand our vision of textbooks further by showing how they perform various hybrid functions in scientific development.

Mota, Fabio Batista; Fonseca, Bruna de Paula Fonseca E; Galina, Andréia Cristina; Silva, Roseli Monteiro da

2017-05-01

Despite the current global trend of reduction in the morbidity and mortality of neglected diseases, dengue's incidence has increased and occurrence areas have expanded. Dengue also persists as a scientific and technological challenge since there is no effective treatment, vaccine, vector control or public health intervention. Combining bibliometrics and social network analysis methods can support the mapping of dengue research and development (R&D) activities worldwide. The aim of this paper is to map the scientific scenario related to dengue research worldwide. We use scientific publication data from Web of Science Core Collection - articles indexed in Science Citation Index Expanded (SCI-EXPANDED) - and combine bibliometrics and social network analysis techniques to identify the most relevant journals, scientific references, research areas, countries and research organisations in the dengue scientific landscape. Our results show a significant increase of dengue publications over time; tropical medicine and virology as the most frequent research areas and biochemistry and molecular biology as the most central area in the network; USA and Brazil as the most productive countries; and Mahidol University and Fundação Oswaldo Cruz as the main research organisations and the Centres for Disease Control and Prevention as the most central organisation in the collaboration network. Our findings can be used to strengthen a global knowledge platform guiding policy, planning and funding decisions as well as to providing directions to researchers and institutions. So that, by offering to the scientific community, policy makers and public health practitioners a mapping of the dengue scientific landscape, this paper has aimed to contribute to upcoming debates, decision-making and planning on dengue R&D and public health strategies worldwide.

Semantic Data Integration and Knowledge Management to Represent Biological Network Associations.

PubMed

Losko, Sascha; Heumann, Klaus

2017-01-01

The vast quantities of information generated by academic and industrial research groups are reflected in a rapidly growing body of scientific literature and exponentially expanding resources of formalized data, including experimental data, originating from a multitude of "-omics" platforms, phenotype information, and clinical data. For bioinformatics, the challenge remains to structure this information so that scientists can identify relevant information, to integrate this information as specific "knowledge bases," and to formalize this knowledge across multiple scientific domains to facilitate hypothesis generation and validation. Here we report on progress made in building a generic knowledge management environment capable of representing and mining both explicit and implicit knowledge and, thus, generating new knowledge. Risk management in drug discovery and clinical research is used as a typical example to illustrate this approach. In this chapter we introduce techniques and concepts (such as ontologies, semantic objects, typed relationships, contexts, graphs, and information layers) that are used to represent complex biomedical networks. The BioXM™ Knowledge Management Environment is used as an example to demonstrate how a domain such as oncology is represented and how this representation is utilized for research.

Expanding the knowledge translation metaphor.

PubMed

Engebretsen, Eivind; Sandset, Tony Joakim; Ødemark, John

2017-03-13

Knowledge translation (KT) is a buzzword in modern medical science. However, there has been little theoretical reflection on translation as a process of meaning production in KT. In this paper, we argue that KT will benefit from the incorporation of a more theoretical notion of translation as an entangled material, textual and cultural process. We discuss and challenge fundamental assumptions in KT, drawing on theories of translation from the human sciences. We show that the current construal of KT as separate from and secondary to the original scientific message is close to the now deeply compromised literary view of translation as the simple act of copying the original. Inspired by recent theories of translation, we claim that KT can be more adequately understood in terms of a 'double supplement' - on the one hand, KT offers new approaches to the communication of scientific knowledge to different groups in the healthcare system with the aim of supplementing a lack of knowledge among clinicians (and patients). On the other, it demonstrates that a textual and cultural supplement, namely a concern with target audiences (clinicians and patients), is inevitable in the creation of an 'autonomous' science. Hence, the division between science and its translation is unproductive and impossible to maintain. We discuss some possible implications of our suggested shift in concept by drawing on pharmaceutical interventions for the prevention of HIV as a case. We argue that such interventions are based on a supplementary and paradoxical relation to the target audiences, both presupposing and denying their existence. More sophisticated theories of translation can lay the foundation for an expanded model of KT that incorporates a more adequate and reflective description of the interdependency of scientific, cultural, textual and material practices.

2010-01-01

As human impacts cause ecosystem-wide changes in the oceans, the need to protect and restore marine resources has led to increasing calls for and establishment of marine reserves. Scientific information about marine reserves has multiplied over the last decade, providing useful knowledge about this tool for resource users, managers, policy makers, and the general public. This information must be conveyed to nonscientists in a nontechnical, credible, and neutral format, but most scientists are not trained to communicate in this style or to develop effective strategies for sharing their scientific knowledge. Here, we present a case study from California, in which communicating scientific information during the process to establish marine reserves in the Channel Islands and along the California mainland coast expanded into an international communication effort. We discuss how to develop a strategy for communicating marine reserve science to diverse audiences and highlight the influence that effective science communication can have in discussions about marine management.

Disease management research using event graphs.

Allore, H G; Schruben, L W

2000-08-01

Event Graphs, conditional representations of stochastic relationships between discrete events, simulate disease dynamics. In this paper, we demonstrate how Event Graphs, at an appropriate abstraction level, also extend and organize scientific knowledge about diseases. They can identify promising treatment strategies and directions for further research and provide enough detail for testing combinations of new medicines and interventions. Event Graphs can be enriched to incorporate and validate data and test new theories to reflect an expanding dynamic scientific knowledge base and establish performance criteria for the economic viability of new treatments. To illustrate, an Event Graph is developed for mastitis, a costly dairy cattle disease, for which extensive scientific literature exists. With only a modest amount of imagination, the methodology presented here can be seen to apply modeling to any disease, human, plant, or animal. The Event Graph simulation presented here is currently being used in research and in a new veterinary epidemiology course. Copyright 2000 Academic Press.

Social Network and Content Analysis of the North American Carbon Program as a Scientific Community of Practice

Brown, Molly E.; Ihli, Monica; Hendrick, Oscar; Delgado-Arias, Sabrina; Escobar, Vanessa M.; Griffith, Peter

2015-01-01

The North American Carbon Program (NACP) was formed to further the scientific understanding of sources, sinks, and stocks of carbon in Earth's environment. Carbon cycle science integrates multidisciplinary research, providing decision-support information for managing climate and carbon-related change across multiple sectors of society. This investigation uses the conceptual framework of com-munities of practice (CoP) to explore the role that the NACP has played in connecting researchers into a carbon cycle knowledge network, and in enabling them to conduct physical science that includes ideas from social science. A CoP describes the communities formed when people consistently engage in shared communication and activities toward a common passion or learning goal. We apply the CoP model by using keyword analysis of abstracts from scientific publications to analyze the research outputs of the NACP in terms of its knowledge domain. We also construct a co-authorship network from the publications of core NACP members, describe the structure and social pathways within the community. Results of the content analysis indicate that the NACP community of practice has substantially expanded its research on human and social impacts on the carbon cycle, contributing to a better understanding of how human and physical processes interact with one another. Results of the co-authorship social network analysis demonstrate that the NACP has formed a tightly connected community with many social pathways through which knowledge may flow, and that it has also expanded its network of institutions involved in carbon cycle research over the past seven years.

Bridging the gap between knowledge and health: the epidemiologist as Accountable Health Advocate ("AHA!").

PubMed

Dowdy, David W; Pai, Madhukar

2012-11-01

Epidemiology occupies a unique role as a knowledge-generating scientific discipline with roots in the knowledge translation of public health practice. As our fund of incompletely-translated knowledge expands and as budgets for health research contract, epidemiology must rediscover and adapt its historical skill set in knowledge translation. The existing incentive structures of academic epidemiology - designed largely for knowledge generation - are ill-equipped to train and develop epidemiologists as knowledge translators. A useful heuristic is the epidemiologist as Accountable Health Advocate (AHA) who enables society to judge the value of research, develops new methods to translate existing knowledge into improved health, and actively engages with policymakers and society. Changes to incentive structures could include novel funding streams (and review), alternative publication practices, and parallel frameworks for professional advancement and promotion.

Nectar for the taking: the popularization of scientific bee culture in England, 1609-1809.

PubMed

Ebert, Adam

2011-01-01

This essay expands and refines academic knowledge of English beekeeping during the seventeenth and eighteenth centuries. Scientific beekeeping focused on improvement, which, in turn, depended on the dissemination of ideas and practices. This analysis, therefore, encompasses the mentalities and tactics of popularizers. The article also identifies two neglected concepts in the popularization campaign. First, popularizers saw scientific beekeeping as a way to end the tradition of killing the bees in order to safely harvest. Second, they sought to promote a rural industry for the economic welfare of the nation. The case study of Exeter's Western Apiarian Society reveals precisely how popularization functioned in reality. The result is a more thorough history of scientific beekeeping and how the rhetoric of improvement related to the culture of practice.

The Earth expansion theory and its transition from scientific hypothesis to pseudoscientific belief

NASA Astrophysics Data System (ADS)

Sudiro, P.

2014-06-01

During the first half of 20th century, the dominant global tectonics model based on Earth contraction had increasing problems accommodating new geological evidence, with the result that alternative geodynamic theories were investigated. Due to the level of scientific knowledge and the limited amount of data available in many scientific disciplines at the time, not only was contractionism considered a valid scientific theory but the debate also included expansionism, mobilism on a fixed-dimension planet, or various combinations of these geodynamic hypotheses. Geologists and physicists generally accepted that planets could change their dimensions, although the change of volume was generally believed to happen because of a contraction, not an expansion. Constant generation of new matter in the universe was a possibility accepted by science, as it was the variation in the cosmological constants. Continental drift, instead, was a more heterodox theory, requiring a larger effort from the geoscientists to be accepted. The new geological data collected in the following decades, an improved knowledge of the physical processes, the increased resolution and penetration of geophysical tools, and the sensitivity of measurements in physics decreased the uncertainty level in many fields of science. Theorists now had less freedom for speculation because their theories had to accommodate more data, and more limiting conditions to respect. This explains the rapid replacement of contracting Earth, expanding Earth, and continental drift theories by plate tectonics once the symmetrical oceanic magnetic striping was discovered, because none of the previous models could explain and incorporate the new oceanographic and geophysical data. Expansionism could survive after the introduction of plate tectonics because its proponents have increasingly detached their theory from reality by systematically rejecting or overlooking any contrary evidence, and selectively picking only the data that support expansion. Moreover, the proponents continue to suggest imaginative physical mechanisms to explain expansion, claiming that scientific knowledge is partial, and the many inconsistencies of their theory are just minor problems in the face of the plain evidence of expansion. According to the expansionists, scientists should just wait for some revolutionary discovery in fundamental physics that will explain all the unsolved mysteries of Earth expansion. The history of the expanding-Earth theory is an example of how falsified scientific hypotheses can survive their own failure, gradually shifting towards and beyond the limits of scientific investigation until they become merely pseudoscientific beliefs.

Expanding the use of empiricism in nursing: can we bridge the gap between knowledge and clinical practice?

PubMed

Giuliano, Karen K

2003-04-01

The philosophy of Aristotle and its impact on the process of empirical scientific inquiry has been substantial. The influence of the clarity and orderliness of his thinking, when applied to the acquisition of knowledge in nursing, can not be overstated. Traditional empirical approaches have and will continue to have an important influence on the development of nursing knowledge through nursing research. However, as nursing is primarily a practice discipline, the transition from empirical and syllogistic reasoning is problematic. Other types of inquiry are essential in the application of nursing knowledge obtained by empirical scientific approaches and to understand how that knowledge can best be used in the care of patients. This paper reviews the strengths and limitations of syllogistic reasoning by applying it to a recently published study on temperature measurement in nursing. It then discusses possible ways that the empirical knowledge gained from that study and confirmed in its reasoning by logical analysis could be used in the daily care of critically ill patients. It concludes by highlighting the utility of broader approaches to knowledge development, including interpretative approaches and contemporary empiricism, as a way to bridge the gap between factual empirical knowledge and the practical application of that knowledge in everyday clinical nursing practice.

Alaskan Salmon and Gen R: hunting, fishing to cultivate ecological mindfulness

Can mining and fisheries co-exist in Bristol Bay, Alaska? To delve into this interesting tension, I expand on Clay Pierce's (this special issue) thoughtful analysis of genetically modified salmon and AquaBounty Technologies, where he explores actor-network theory in relation to scientific literacy and schooling. Further, my essay explores the idea of embodied knowledge as paramount to the next generation of youth engaged with scientific literacy. I demonstrate the problems associated with using hegemonic science to normalize biocapitalism and the subjugated knowledges in relation. Ultimately, I provide justifications for strengthening an ecologically mindful scientific literacy, working towards what might be called "Neptunian democracy" in science education, including salmon and other nonhuman actors as integral for youth wrestling with ecojustice issues. To do this, I highlight the significance of renewing fishing, hunting, and salmon eating. These things ought to become an intimate characteristic of the imagined literacy of the next generation of youth (what I've been calling Generation R for responsibility).

Science, Technology and Innovation as Social Goods for Development: Rethinking Research Capacity Building from Sen's Capabilities Approach.

PubMed

Mormina, Maru

2018-03-01

Science and technology are key to economic and social development, yet the capacity for scientific innovation remains globally unequally distributed. Although a priority for development cooperation, building or developing research capacity is often reduced in practice to promoting knowledge transfers, for example through North-South partnerships. Research capacity building/development tends to focus on developing scientists' technical competencies through training, without parallel investments to develop and sustain the socioeconomic and political structures that facilitate knowledge creation. This, the paper argues, significantly contributes to the scientific divide between developed and developing countries more than any skills shortage. Using Charles Taylor's concept of irreducibly social goods, the paper extends Sen's Capabilities Approach beyond its traditional focus on individual entitlements to present a view of scientific knowledge as a social good and the capability to produce it as a social capability. Expanding this capability requires going beyond current fragmented approaches to research capacity building to holistically strengthen the different social, political and economic structures that make up a nation's innovation system. This has implications for the interpretation of human rights instruments beyond their current focus on access to knowledge and for focusing science policy and global research partnerships to design approaches to capacity building/development beyond individual training/skills building.

Interstellar exploration will advance human knowledge and culture in multiple ways. Scientifically, it will advance our understanding of the interstellar medium, stellar astrophysics, planetary science and astrobiology. In addition, significant societal and cultural benefits will result from a programme of interstellar exploration and colonisation. Most important will be the cultural stimuli resulting from expanding the horizons of human experience, and increased opportunities for the spread and diversification of life and culture through the Galaxy. Ultimately, a programme of interstellar exploration may be the only way for human (and post-human) societies to avoid the intellectual stagnation predicted for the `end of history'.

Testing Drugs and Trying Cures: Experiment and Medicine in Medieval and Early Modern Europe.

This article examines traditions of testing drugs (as substances) and trying cures (on patients) in medieval and early modern Europe. It argues that the history of drug testing needs to be a more central story to overall histories of scientific experiment. The practice of conducting thoughtful-and sometimes contrived-tests on drugs has a rich and varied tradition dating back to antiquity, which expanded in the Middle Ages and early modern period. Learned physicians paired text-based knowledge (reason) with hands-on testing (experience or experiment) in order to make claims about drugs' properties or effects on humans. Lay practitioners similarly used hands-on testing to gain knowledge of pharmaceutical effects. Although drug testing practices expanded in scale, actors, and sites, therpublished a work extolling the virtues of drugs froe was significant continuity from the Middle Ages to the eighteenth century.

An initiative to increase biopharmaceutical research productivity by capturing, sharing and computationally integrating proprietary scientific discoveries with public knowledge is described. This initiative involves both organisational process change and multiple interoperating software systems. The software components rely on mutually supporting integration techniques. These include a richly structured ontology, statistical analysis of experimental data against stored conclusions, natural language processing of public literature, secure document repositories with lightweight metadata, web services integration, enterprise web portals and relational databases. This approach has already begun to increase scientific productivity in our enterprise by creating an organisational memory (OM) of internal research findings, accessible on the web. Through bringing together these components it has also been possible to construct a very large and expanding repository of biological pathway information linked to this repository of findings which is extremely useful in analysis of DNA microarray data. This repository, in turn, enables our research paradigm to be shifted towards more comprehensive systems-based understandings of drug action.

We developed a "continual engagement" model to better integrate knowledge from policy makers, communities, and researchers with the goal of promoting more effective action to balance poverty alleviation and wildlife conservation in 4 pastoral ecosystems of East Africa. The model involved the creation of a core boundary-spanning team, including community facilitators, a policy facilitator, and transdisciplinary researchers, responsible for linking with a wide range of actors from local to global scales. Collaborative researcher-facilitator community teams integrated local and scientific knowledge to help communities and policy makers improve herd quality and health, expand biodiversity payment schemes, develop land-use plans, and fully engage together in pastoral and wildlife policy development. This model focused on the creation of hybrid scientific-local knowledge highly relevant to community and policy maker needs. The facilitation team learned to be more effective by focusing on noncontroversial livelihood issues before addressing more difficult wildlife issues, using strategic and periodic engagement with most partners instead of continual engagement, and reducing costs by providing new scientific information only when deemed essential. We conclude by examining the role of facilitation in redressing asymmetries in power in researcher-community-policy maker teams, the role of individual values and character in establishing trust, and how to sustain knowledge-action links when project funding ends.

Scientific reference management has become crucial in rapidly expanding fields of biology. Many of the reference management systems currently employed are reference centric and not object/process focused. BrainSnail is a reference management/knowledge representation application that tries to bridge disconnect between subject and reference in the fields of neuropharmacology, neuroanatomy and neurophysiology. BrainSnail has been developed with considering both individual researcher and research group efforts. PMID:19293992

Objectivity, abstraction, and the individual: the influence of Søren Kierkegaard on Paul Feyerabend.

PubMed

Kidd, Ian James

2011-03-01

This paper explores the influence of Søren Kierkegaard upon Paul Feyerabend by examining their common criticisms of totalising accounts of human nature. Both complained that philosophical and scientific theories of human nature which were methodologically committed to objectivity and abstraction failed to capture the richness of human experience. Kierkegaard and Feyerabend argued that philosophy and the science were threatening to become obstacles to human development by imposing abstract theories of human nature and reality which denied the complexities of both. In both cases, this took the form of asserting an 'existential' criterion for the assessment of philosophical and scientific theories. Kierkegaard also made remarks upon the inappropriateness of applying natural scientific methods to human beings which Feyerabend later expanded and developed in his criticisms of the inability of the 'scientific world-view' to accommodate the values necessary to a flourishing human life. I conclude by noting some differences between Kierkegaard and Feyerabend's positions and by affirming the value of existential criticisms of scientific knowledge.

The Pioneering Role of the Vaccine Safety Datalink Project (VSD) to Advance Collaborative Research and Distributed Data Networks

2015-01-01

Introduction: Large-scale distributed data networks consisting of diverse stakeholders including providers, patients, and payers are changing health research in terms of methods, speed and efficiency. The Vaccine Safety Datalink (VSD) set the stage for expanded involvement of health plans in collaborative research. Expanding Surveillance Capacity and Progress Toward a Learning Health System: From an initial collaboration of four integrated health systems with fewer than 10 million covered lives to 16 diverse health plans with nearly 100 million lives now in the FDA Sentinel, the expanded engagement of health plan researchers has been essential to increase the value and impact of these efforts. The collaborative structure of the VSD established a pathway toward research efforts that successfully engage all stakeholders in a cohesive rather than competitive manner. The scientific expertise and methodology developed through the VSD such as rapid cycle analysis (RCA) to conduct near real-time safety surveillance allowed for the development of the expanded surveillance systems that now exist. Building on Success and Lessons Learned: These networks have learned from and built on the knowledge base and infrastructure created by the VSD investigators. This shared technical knowledge and experience expedited the development of systems like the FDA’s Mini-Sentinel and the Patient Centered Outcomes Research Institute (PCORI)’s PCORnet Conclusion: This narrative reviews the evolution of the VSD, its contribution to other collaborative research networks, longer-term sustainability of this type of distributed research, and how knowledge gained from the earlier efforts can contribute to a continually learning health system.

Traditional Ecological Knowledge (TEK) and folklore are repositories of large amounts of information about the natural world. Ideas, perceptions and empirical data held by human communities regarding local species are important sources which enable new scientific discoveries to be made, as well as offering the potential to solve a number of conservation problems. We documented the gecko-related folklore and TEK of the people of southern Portugal, with the particular aim of understanding the main ideas relating to gecko biology and ecology. Our results suggest that local knowledge of gecko ecology and biology is both accurate and relevant. As a result of information provided by local inhabitants, knowledge of the current geographic distribution of Hemidactylus turcicus was expanded, with its presence reported in nine new locations. It was also discovered that locals still have some misconceptions of geckos as poisonous and carriers of dermatological diseases. The presence of these ideas has led the population to a fear of and aversion to geckos, resulting in direct persecution being one of the major conservation problems facing these animals. It is essential, from both a scientific and conservationist perspective, to understand the knowledge and perceptions that people have towards the animals, since, only then, may hitherto unrecognized pertinent information and conservation problems be detected and resolved.

Expanding Advanced Civilizations in the Universe

NASA Astrophysics Data System (ADS)

Gros, C.

The 1950 lunch-table remark by Enrico Fermi `Where is everybody' has started intensive scientific and philosophical discussions about what we call nowadays the `Fermi paradox': If there had been ever a single advanced civilization in the cosmological history of our galaxy, dedicated to expansion, it would have had plenty of time to colonize the entire galaxy via exponential growth. No evidence of present or past alien visits to earth are known to us, leading to the standard conclusion that no advanced expanding civilization has ever existed in the milky-way. This conclusion rest fundamentally on the ad-hoc assumption, that any alien civilizations dedicated to expansion at one time would remain dedicated to expansions forever. Considering our limited knowledge about alien civilizations we need however to relax this basic assumption. Here we show that a substantial and stable population of expanding advanced civilization might consequently exist in our galaxy.

Tolzman, Jean M.

1993-01-01

The potential for expanded communication among researchers, scholars, and students is supported by growth in the capabilities for electronic communication as well as expanding access to various forms of electronic interchange and computing capabilities. Increased possibilities for information exchange, collegial dialogue, collaboration, and access to remote resources exist as high-speed networks, increasingly powerful workstations, and large, multi-user computational facilities are more frequently linked and more commonly available. Numerous writers speak of the telecommunications revolution and its impact on the development and dissemination of knowledge and learning. One author offers the phrase 'Scholarly skywriting' to represent a new form of scientific communication that he envisions using electronic networks. In the United States (U.S.), researchers associated with the National Science Foundation (NSF) are exploring 'nationwide collaboratories' and 'digital collaboration.' Research supported by the U.S. National Aeronautics and Space Administration (NASA) points to a future where workstations with built-in audio, video monitors, and screen sharing protocols are used to support collaborations with colleagues located throughout the world. Instruments and sensors located worldwide will produce data streams that will be brought together, analyzed, and distributed as new findings. Researchers will have access to machines that can supply domain-specific information in addition to locator and directory assistance. New forms of electronic journals will emerge and provide opportunities for researchers and scientists to exchange information electronically and interactively in a range of structures and formats. Ultimately, the wide-scale use of these technologies in the dissemination of research results and the stimulation of collegial dialogue will change the way we represent and express our knowledge of the world. A new paradigm will evolve--perhaps a truly worldwide 'invisible college.'

Ecoacoustic Music for Geoscience: Sonic Physiographies and Sound Casting

NASA Astrophysics Data System (ADS)

Burtner, M.

2017-12-01

The author describes specific ecoacoustic applications in his original compositions, Sonic Physiography of a Time-Stretched Glacier (2015), Catalog of Roughness (2017), Sound Cast of Matanuska Glacier (2016) and Ecoacoustic Concerto (Eagle Rock) (2014). Ecoacoustic music uses technology to map systems from nature into music through techniques such as sonification, material amplification, and field recording. The author aspires for this music to be descriptive of the data (as one would expect from a visualization) and also to function as engaging and expressive music/sound art on its own. In this way, ecoacoustic music might provide a fitting accompaniment to a scientific presentation (such as music for a science video) while also offering an exemplary concert hall presentation for a dedicated listening public. The music can at once support the communication of scientific research, and help science make inroads into culture. The author discusses how music created using the data, sounds and methods derived from earth science can recast this research into a sonic art modality. Such music can amplify the communication and dissemination of scientific knowledge by broadening the diversity of methods and formats we use to bring excellent scientific research to the public. Music can also open the public's imagination to science, inspiring curiosity and emotional resonance. Hearing geoscience as music may help a non-scientist access scientific knowledge in new ways, and it can greatly expand the types of venues in which this work can appear. Anywhere music is played - concert halls, festivals, galleries, radio, etc - become a venue for scientific discovery.

A pervasive denigration of natural history misconstrues how biodiversity inventories and taxonomy underpin scientific knowledge

PubMed Central

2011-01-01

Embracing comparative biology, natural history encompasses those sciences that discover, decipher and classify unique (idiographic) details of landscapes, and extinct and extant biodiversity. Intrinsic to these multifarious roles in expanding and consolidating research and knowledge, natural history endows keystone support to the veracity of law-like (nomothetic) generalizations in science. What science knows about the natural world is governed by an inherent function of idiographic discovery; characteristic of natural history, this relationship is exemplified wherever an idiographic discovery overturns established wisdom. This nature of natural history explicates why inventories are of such epistemological importance. Unfortunately, a Denigration of Natural History weakens contemporary science from within. It expresses in the prevalent, pervasive failure to appreciate this pivotal role of idiographic research: a widespread disrespect for how natural history undergirds scientific knowledge. Symptoms of this Denigration of Natural History present in negative impacts on scientific research and knowledge. One symptom is the failure to appreciate and support the inventory and monitoring of biodiversity. Another resides in failures of scientiometrics to quantify how taxonomic publications sustain and improve knowledge. Their relevance in contemporary science characteristically persists and grows; so the temporal eminence of these idiographic publications extends over decades. This is because they propagate a succession of derived scientific statements, findings and/or conclusions - inherently shorter-lived, nomothetic publications. Widespread neglect of natural science collections is equally pernicious, allied with disregard for epistemological functions of specimens, whose preservation maintains the veracity of knowledge. Last, but not least, the decline in taxonomic expertise weakens research capacity; there are insufficient skills to study organismal diversity in all of its intricacies. Beyond weakening research capacities and outputs across comparative biology, this Denigration of Natural History impacts on the integrity of knowledge itself, undermining progress and pedagogy throughout science. Unprecedented advances in knowledge are set to follow on consummate inventories of biodiversity, including the protists. These opportunities challenge us to survey biodiversity representatively—detailing the natural history of species. Research strategies cannot continue to ignore arguments for such an unprecedented investment in idiographic natural history. Idiographic shortcuts to general (nomothetic) insights simply do not exist. The biodiversity sciences face a stark choice. No matter how charismatic its portrayed species, an incomplete ‘Brochure of Life’ cannot match the scientific integrity of the ‘Encyclopedia of Life’. PMID:21472034

2014-08-01

The concept and principles of evidence-based medicine (EBM), first introduced in 1996 in the UK and Canada, have greatly impacted healthcare worldwide. Evidence-based care is a new approach to healthcare that works to reduce the gap between evidence and practice in order to further the scientific credentials and practices of the nursing profession. The revolution in healthcare has perhaps most noticeably impacted the nursing sciences. Today, new methodologies are increasingly synthesizing knowledge, while expanded access to publication resources is creating a new era in evidence-based nursing. Therefore, we expect to see in Taiwan the increased sharing of innovative implementations of evidence-based nursing practice and promotion campaigns and the exploration of a new evidence-based nursing paradigm for incorporating evidence-based concepts into the policymaking process, nursing practice, and nursing education. All scientists in clinical care, education, and research are responsible to establish scientific nursing knowledge in support of the evidence-based nursing practice.

Scientific Caricatures in the Earth Science Classroom: An Alternative Assessment for Meaningful Science Learning

NASA Astrophysics Data System (ADS)

Clary, Renee M.; Wandersee, James H.

2010-01-01

Archive-based, historical research of materials produced during the Golden Age of Geology (1788-1840) uncovered scientific caricatures (SCs) which may serve as a unique form of knowledge representation for students today. SCs played important roles in the past, stimulating critical inquiry among early geologists and fueling debates that addressed key theoretical issues. When historical SCs were utilized in a large-enrollment college Earth History course, student response was positive. Therefore, we offered SCs as an optional assessment tool. Paired t-tests that compared individual students’ performances with the SC option, as well as without the SC option, showed a significant positive difference favoring scientific caricatures ( α = 0.05). Content analysis of anonymous student survey responses revealed three consistent findings: (a) students enjoyed expressing science content correctly but creatively through SCs, (b) development of SCs required deeper knowledge integration and understanding of the content than conventional test items, and (c) students appreciated having SC item options on their examinations, whether or not they took advantage of them. We think that incorporation of SCs during assessment may effectively expand the variety of methods for probing understanding, thereby increasing the mode validity of current geoscience tests.

Redrawing the frontiers in the age of post-publication review

PubMed Central

Galbraith, David W.

2015-01-01

Publication forms the core structure supporting the development and transmission of scientific knowledge. For this reason, it is essential that the highest standards of quality control be maintained, in particular to ensure that the information being transmitted allows reproducible replication of the described experiments, and that the interpretation of the results is sound. Quality control has traditionally involved editorial decisions based on anonymous pre-publication peer review. Post-publication review of individual articles took the lesser role since it did not feed directly back to the original literature. Rapid advances in computer and communications technologies over the last thirty years have revolutionized scientific publication, and the role and scope of post-publication review has greatly expanded. This perspective examines the ways in which pre- and post-publication peer review influence the scientific literature, and in particular how they might best be redrawn to deal with the twin problems of scientific non-reproducibility and fraud increasingly encountered at the frontiers of science.

Expanding on our previous analysis of Biomedical Informatics (BMI), the present perspective ranges from cybernetics to nanomedicine, based on its scientific, historical, philosophical, theoretical, experimental, and technological aspects as they affect systems developments, simulation and modelling, education, and the impact on healthcare. We then suggest that BMI is still searching for strong basic scientific principles around which it can crystallize. As -omic biological knowledge increasingly impacts the future of medicine, ubiquitous computing and informatics become even more essential, not only for the technological infrastructure, but as a part of the scientific enterprise itself. The Virtual Physiological Human and investigations into nanomedicine will surely produce yet more unpredictable opportunities, leading to significant changes in biomedical research and practice. As a discipline involved in making such advances possible, BMI is likely to need to re-define itself and extend its research horizons to meet the new challenges.

2012-01-01

The availability of genome sequencing data in combination with knowledge of expressed genes via transcriptome and proteome data has greatly advanced our understanding of arthropod vectors of disease. Not only have we gained insight into vector biology, but also into their respective vector-pathogen interactions. By combining the strengths of postgenomic databases and reverse genetic approaches such as RNAi, the numbers of available drug and vaccine targets, as well as number of transgenes for subsequent transgenic or paratransgenic approaches, have expanded. These are now paving the way for in-field control strategies of vectors and their pathogens. Basic scientific questions, such as understanding the basic components of the vector RNAi machinery, is vital, as this allows for the transfer of basic RNAi machinery components into RNAi-deficient vectors, thereby expanding the genetic toolbox of these RNAi-deficient vectors and pathogens. In this review, we focus on the current knowledge of arthropod vector RNAi machinery and the impact of RNAi on understanding vector biology and vector-pathogen interactions for which vector genomic data is available on VectorBase.

Epistemological beliefs and epistemological practices in elementary science

NASA Astrophysics Data System (ADS)

Kittleson, Julie M.

In this study, I examined the reciprocal relationship between third graders' epistemological beliefs and practices in the context of science instruction. Epistemological beliefs describe students' ideas about the nature of knowledge. Epistemological practices describe how students interact with dimensions of scientific knowledge. Examining the intersection between beliefs and practices involves describing how participating in science learning activities influences and is influenced by ideas about science. To examine beliefs and practices, I used interviews and classroom observations. Interview data were analyzed to ascertain students' ideas about the purpose of science and the justification, certainty, and structure/coherence of scientific knowledge. Additionally, lessons in the FOSS Human Body unit and the STC Chemical Tests unit were video taped. These data were analyzed to examine epistemological practices. Interview and classroom data were used in combination to explore the intersection between beliefs and practices. Students held multifaceted ideas about science. They indicated that science involves description, but they also indicated that science involves generating evidence and drawing conclusions. Students indicated that ideas can change in relation to new evidence. Epistemological practices, in contrast, revealed that the investigation strategies invoked in these units underestimated students' ideas about science. Students used matching strategies to complete investigations. In the Chemical Tests unit, the teacher helped students move beyond matching by introducing the idea of molecules. Students discussed molecules in relation to their empirical investigations, indicating that when elementary students are provided with appropriate scaffolds they can expand their range of practices which also potentially expands their beliefs. Students approached science as a repertoire of tests. They recalled ideas about the purpose of a test in one context and applied those ideas to another context. Additionally, they suggested that certain tests are appropriate for certain situations. Although students understood the purpose of the tests, they did not seem to recognize the full range of purposes underlying scientific investigations. This study highlights the challenge of designing learning environments that scaffold productive epistemological beliefs. This study also highlights the complexity of the relationship between beliefs and practices, particularly in terms of understanding the role instruction might play in mediating this relationship.

The study and practice of medicine, in its most personal and intimate functions, its most sophisticated scientific and technological manifestations, and its philosophical and ethical ramifications, are central to our understanding of the human condition. Homeopathic medicine: its insights, the questions that it begs, and the scientific and philosophical challenges it presents, has a significant contribution to make to this process. To be actively and seriously engaged with homeopathy is an adventurous undertaking. It is to be engaged in exploring both human nature and the nature of the world we inhabit. And in that process we are also engaged in the pursuit of truth and the exploration of reality. This paper deals first with the layout of the playing field on which homeopathy has to compete to be taken seriously. It then discusses three concepts: reality, truth and knowledge, which are objectives for which we strive and principles that guide us in that striving. In the third part it introduces the concept of 'personal knowledge' as an essential ingredient of scientific discovery and the pursuit of truth. And finally it proposes that the homeopathic community in general, and the Faculty of Homeopathy in particular, must expand its vision with a definition of a new paradigm, the new model of healthcare and medical science to which the vision aspires.

Research and technology, 1987

1987-01-01

Three broad goals were presented by NASA as a guide to meet the challenges of the future: to advance scientific knowledge of the planet Earth, the solar system, and the universe; to expand human presence beyond the Earth into the solar system; and to strengthen aeronautics research and technology. Near-term and new-generation space transportation and propulsion systems are being analyzed that will assure the nation access to and presence in space. Other key advanced studies include large astronomical observatories, space platforms, scientific and commercial payloads, and systems to enhance operations in Earth orbit. Longer-range studies include systems that would allow humans to explore the Moon and Mars during the next century. Research programs, both to support the many space missions studied or managed by the Center and to advance scientific knowledge in selected areas, involve work in the areas of atmospheric science, earth science, space science (including astrophysics and solar, magnetospheric, and atomic physics), and low-gravity science. Programs and experiment design for flights on the Space Station, free-flying satellites, and the Space Shuttle are being planned. To maintain a leadership position in technology, continued advances in liquid and solid propellant engines, materials and processes; electronic, structural, and thermal investigations; and environmental control are required. Progress during the fiscal year 1987 is discussed.

Libration point orbits serve as excellent platforms for scientific investigations involving the Sun as well as planetary environments. Trajectory design in support of such missions is increasingly challenging as more complex missions are envisioned in the next few decades. Software tools for trajectory design in this regime must be further developed to incorporate better understanding of the solution space and, thus, improve the efficiency and expand the capabilities of current approaches. Only recently applied to trajectory design, dynamical systems theory now offers new insights into the natural dynamics associated with the multi-body problem. The goal of this effort is the blending of analysis from dynamical systems theory with the well established NASA Goddard software program SWINGBY to enhance and expand the capabilities for mission design. Basic knowledge concerning the solution space is improved as well.

CHEMICAL REACTIONS AS PETITE RENDEZVOUS: THE USE OF METAPHOR IN MATERIALS SCIENCE EDUCATION

Uskoković, Vuk

2015-01-01

Every time we communicate our science, we are involuntarily involved in an educational activity, affecting the listeners’ methodology and motivation. In a beautiful metaphor, late Nobel Laureate, Richard E. Smalley compared interacting atoms and molecules to boys and girls falling in love. Elaborated and exemplified with a couple of entertaining analogies in this discourse is the effectiveness of the use of metaphors in illustrating scientific concepts to both scientific novices and peers. Human brain has been considered to be a complex neural circuitry for the computation of metaphors, which explains the naturalness of their usage, especially when solid arguments could be given in support of the thesis that scientific imagery in general presents a collection of mathematically operable metaphors. On top of this, knowledge could be enriched through logic alone, but new concepts could be learned only through analogies. The greater pervasion of metaphors in scientific presentations could boost their inspirational potential, make the audience more attentive and receptive to their contents, and, finally, expand their educational prospect and enable their outreach to a far broader audience than it has been generally accomplished.

Toward Routine Automatic Pathway Discovery from On-line Scientific Text Abstracts.

PubMed

Ng; Wong

1999-01-01

We are entering a new era of research where the latest scientific discoveries are often first reported online and are readily accessible by scientists worldwide. This rapid electronic dissemination of research breakthroughs has greatly accelerated the current pace in genomics and proteomics research. The race to the discovery of a gene or a drug has now become increasingly dependent on how quickly a scientist can scan through voluminous amount of information available online to construct the relevant picture (such as protein-protein interaction pathways) as it takes shape amongst the rapidly expanding pool of globally accessible biological data (e.g. GENBANK) and scientific literature (e.g. MEDLINE). We describe a prototype system for automatic pathway discovery from on-line text abstracts, combining technologies that (1) retrieve research abstracts from online sources, (2) extract relevant information from the free texts, and (3) present the extracted information graphically and intuitively. Our work demonstrates that this framework allows us to routinely scan online scientific literature for automatic discovery of knowledge, giving modern scientists the necessary competitive edge in managing the information explosion in this electronic age.

The development and implementation of a scientific outreach activity comes with a number of challenges. A successful outreach event must match the sophistication of content to the audience, be engaging, expand the knowledge base for participants, and be inclusive for a diverse audience. Ideally, a successful event will also convey the importance of scientific outreach for future scientists and citizens. In this paper, we present a simple, hands-on guide to a scientific outreach event targeted to kindergarten learners. This activity also pursued a second goal: the inclusion of undergraduate students in the development and delivery of the event. We provided a detailed set of four activities, focusing on the blind Mexican cavefish, which were enthusiastically received by kindergarten audiences. The engagement of undergraduate students in the development of this activity encouraged public outreach involvement and fostered new scientific and communication skills. The format of the outreach event we describe is flexible. We provide a set of guidelines and suggestions for adapting this approach to other biological topics. The activity and approach we describe enables the implementation of effective scientific outreach, using active learning approaches, which benefits both elementary school learners and undergraduate students.

Identifying geoscience knowledge likely to affect foreign policy

NASA Astrophysics Data System (ADS)

Kelmelis, J. A.

2006-12-01

The earth sciences play an important role in foreign policy and have done so throughout history. Whether it is access to resources, knowledge of weather or other earth system conditions, planning for or responding to disasters, protecting the environment, facilitating transportation and communication, or any of a number of other important topics, the geosciences continue to inform our decision making. The importance of science, technology, and health (STH) is being increasingly recognized in the foreign policy community. The National Research Council (NRC) recommended that the Department of State (State) expand its scientific base to address the importance of STH issues. In part, this consists of increasing the number of scientists within State. Another important aspect is not only identifying the STH issues that are of current concern, but also the issues that will be of importance in the future. A number of studies funded by the U.S. Government have identified some important STH areas of concern at a high level. These provide a basis for more in-depth investigations. However, there are additional phenomena, beyond those identified in the studies, which have foreign policy implications. The scientific findings may be well known to scientists but their foreign policy importance is not always obvious. The scientific and foreign policy communities could improve their dialog to better develop strategies for foreign policy and future scientific research. One way to help facilitate that is to ease identification of scientific issues with potential significance to foreign policy and to clarify uncertainties around those issues. A qualitative method relating the likelihood that the scientific finding has foreign policy importance to the potential level of foreign policy importance has been used to clarify the significance of a variety of scientific findings including Arctic warming, methane hydrates, atmospheric dust, disease, and natural hazards. From a foreign policy perspective, the significance of some scientific findings can cascade through emerging international issues and manifest themselves in ways that have both strategic and tactical concern.

Inner-city high school students are disproportionately affected by health problems that stem from environmental conditions. Also, they are not adequately prepared in Science -- especially in the concepts, methods, and procedures of environmental-health science research -- and are generally unaware of the career opportunities in this field. A Superfund program was developed to increase Science literacy and expand career knowledge in environmental health among a cohort of minority high school students from New York City. The year-round program features lectures, laboratory tours, seminars, investigations, and research taught by faculty and Superfund investigators at Mount Sinai`s Environmental Health Sciences Center.

New frontiers for zebrafish management.

PubMed

Lawrence, C

2016-01-01

The zebrafish (Danio rerio) is a preeminent model organism with a wide and expanding utility for numerous scientific disciplines. The same features that once endeared this small freshwater minnow to developmental biologists combined with its relatively high genetic similarity to mammals and the advent of new, more efficient methods for genome editing are now helping to spur expanded growth in its usage in various fields, including toxicology, drug discovery, transplant biology, disease modeling, and even aquaculture. Continued maturation and adoption of the zebrafish model system in these and other fields of science will require that methods and approaches for husbandry and management of these fish in controlled settings be refined and improved to the extent that, ultimately, zebrafish research becomes more reproducible, defined, cost-effective, and accessible to the masses. Knowledge and technology transfer from laboratory animal science and commercial aquaculture will be a necessary part of this development. Copyright © 2016 Elsevier Inc. All rights reserved.

Most would agree that these are exciting times in the field of laboratory medicine. As the body of scientific knowledge expands and research activities, such as those catalyzed by the sequencing of the human genome, bring us closer to the promise of personalized medicine, the clinical laboratory industry will have increasing opportunities to partner with owners of intellectual property to develop and commercialize new diagnostic tests. The large, independent clinical laboratories are particularly well positioned to commercialize important new tests, with their broad market penetration, infrastructure, and the scale to run esoteric tests cost-effectively.

Western teachers of science or teachers of Western science: On the influence of Western modern science in a post-colonial context

NASA Astrophysics Data System (ADS)

Burke, Lydia E. Carol-Ann

An expanding body of research explores the social, political, cultural and personal challenges presented by the Western emphasis of curricula around the world. The aim of my study is to advance this field of inquiry by gaining insight into perceptions of Western modern science presented by students, teachers and administrators in a given Caribbean setting. Through this study I asked how my research participants described the nature of scientific knowledge, how they related scientific knowledge to other culturally-valued knowledges and the meanings they attached to the geographic origins of science teachers. Situating this work firmly within the practice of Foucauldian critical discourse analysis, I have utilised a conceptual framework defined by the power/knowledge and complicity/resistance themes of post-colonial theory to support my interpretation of participant commentary in an overall quest that is concerned about the ways in which Western modern science might be exerting a colonising influence. Fourteen students, nine teachers (both expatriate and local) and three administrators participated in the study. I combined a semi-structured question and answer interview format with a card sort activity. I used a procedure based on my own adaptation of Stephenson's Q methodology, where the respondents placed 24 statements hierarchically along a continuum of increasing strength of agreement, presenting their rationalisations, personal stories and illustrations as they sorted. I used an inverse factor analysis, in combination with the interview transcripts, to assist me in the identification of three discourse positions described by my research participants: The truth value of scientific knowledge, The pragmatic use of science to promote progress, and The priority of cultural preservation. The interview transcripts were also analysed for emergent themes, providing an additional layer of data interpretation. The research findings raise concerns regarding the hegemonic potency of certain scientific assumptions and assertions of participants, leading me to emphasise the importance of developing teachers' knowledge of the historical, philosophical and social background of Western modern science as well as focusing on developing the conceptual and intellectual engagement of students with Western modern science without demanding the kind of belief commitment that would insist that students replace alternative modes of meaning making.

Knowledge, language and subjectivities in a discourse community: Ideas we can learn from elementary children about science

NASA Astrophysics Data System (ADS)

Kurth, Lori Ann

2000-10-01

In light of continuing poor performance by American students in school science, feminists and sociocultural researchers have demonstrated that we need to look beyond content to address the science needs of all school children. In this study I examined issues of discourse norms, knowledge, language and subjectivities (meaning personal and social observations and characteristics) in elementary science. Over a two-year period, I used an interpretive methodological approach to investigate science experiences in two first-second and second grade classrooms. I first established some of the norms and characteristics of the discourse communities through case studies of new students attempting to gain entry to whole class conversations. I then examined knowledge, a central focus of science education addressed by a variety of theoretical approaches. In these classrooms students co-constructed and built knowledge in their whole class science conversations sometimes following convergent (similar knowledge) and, at other times, divergent (differing knowledge) paths allowing for broader discourse. In both paths, there was gendered construction of knowledge in which same gender students elaborated the reasoning of previous speakers. In conjunction with these analyses, I examined what knowledge sources the students used in their science conversations. Students drew on a variety of informal and formal knowledge sources including personal experiences, other students, abstract logic and thought experiments, all of which were considered valid. In using sources from both in and out of school, students' knowledge bases were broader than traditional scientific content giving greater access and richness to their conversations. The next analysis focused on students' use of narrative and paradigmatic language forms in the whole class science conversations. Traditionally, only paradigmatic language forms have been used in science classrooms. The students in this study used both narrative and paradigmatic language by drawing on stories of personal experience as well as canonical scientific argument. As had the varied knowledge paths and sources, the use of both language forms contributed to a broader and richer scientific discourse. Finally, in studying students' written discourse through their journals, I found that students had expanded views of science as they incorporated many aspects of their subjective selves including self and human elements, thinking, emotions, etc. in their writing and drawing. The enactment of knowledge, language and subjectivities in these discourse communities was unique, rich and meaningful highlighting a broader, more accessible vision of science. I advocate that knowledge, language and subjectivities should be central concepts in the practices of science communities as demonstrated in these classrooms. In establishing and integrating these concepts, the use of alternative and traditional modes of expression should be supported as both necessary and complementary. Students and teachers must also jointly construct classroom discourse norms, talk and writing in specific ways in order to provide a safe, comfortable and meaningful learning environment. Many teachers, students and scientists would benefit from broader visions of science, which enrich scientific knowledge and practice and engage and value participants from many backgrounds.

Managing bioengineering complexity with AI techniques.

Beal, Jacob; Adler, Aaron; Yaman, Fusun

2016-10-01

Our capabilities for systematic design and engineering of biological systems are rapidly increasing. Effectively engineering such systems, however, requires the synthesis of a rapidly expanding and changing complex body of knowledge, protocols, and methodologies. Many of the problems in managing this complexity, however, appear susceptible to being addressed by artificial intelligence (AI) techniques, i.e., methods enabling computers to represent, acquire, and employ knowledge. Such methods can be employed to automate physical and informational "routine" work and thus better allow humans to focus their attention on the deeper scientific and engineering issues. This paper examines the potential impact of AI on the engineering of biological organisms through the lens of a typical organism engineering workflow. We identify a number of key opportunities for significant impact, as well as challenges that must be overcome. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Effect of electromagnetic waves on human reproduction.

Wdowiak, Artur; Mazurek, Paweł A; Wdowiak, Anita; Bojar, Iwona

2017-03-31

Electromagnetic radiation (EMR) emitting from the natural environment, as well as from the use of industrial and everyday appliances, constantly influence the human body. The effect of this type of energy on living tissues may exert various effects on their functioning, although the mechanisms conditioning this phenomenon have not been fully explained. It may be expected that the interactions between electromagnetic radiation and the living organism would depend on the amount and parameters of the transmitted energy and type of tissue exposed. Electromagnetic waves exert an influence on human reproduction by affecting the male and female reproductive systems, the developing embryo, and subsequently, the foetus. Knowledge concerning this problem is still being expanded; however, all the conditionings of human reproduction still remain unknown. The study presents the current state of knowledge concerning the problem, based on the latest scientific reports.

Huge waves are sculpted in this two-lobed nebula called the Red Spider Nebula, located some 3,000 light-years away in the constellation of Sagittarius. This warm planetary nebula harbors one of the hottest stars known and its powerful stellar winds generate waves 100 billion kilometers (62.4 billion miles) high. The waves are caused by supersonic shocks, formed when the local gas is compressed and heated in front of the rapidly expanding lobes. The atoms caught in the shock emit the spectacular radiation seen in this image. Image credit: ESA/Garrelt Mellema (Leiden University, the Netherlands) NASA image use policy.

This paper reports on the creation of the open access Akustika portal (AKDATA.RU) designed to provide Russian-language easy-to-read and search information on acoustics and related topics. The absence of a Russian-language publication in foreign databases means that it is effectively lost for much of the scientific community. The portal has three interrelated sections: the Akustika information search system (ISS) (Acoustics), full-text archive of the Akusticheskii Zhurnal (Acoustic Journal), and 'Signal'naya informatsiya' ('Signaling information') on acoustics. The paper presents a description of the Akustika ISS, including its structure, content, interface, and information search capabilities for basic and applied research in diverse areas of science, engineering, biology, medicine, etc. The intended users of the portal are physicists, engineers, and engineering technologists interested in expanding their research activities and seeking to increase their knowledge base. Those studying current trends in the Russian-language contribution to international science may also find the portal useful.

Toward critical spatial thinking in the social sciences and humanities.

PubMed

Goodchild, Michael F; Janelle, Donald G

2010-02-01

The integration of geographically referenced information into the conceptual frameworks and applied uses of the social sciences and humanities has been an ongoing process over the past few centuries. It has gained momentum in recent decades with advances in technologies for computation and visualization and with the arrival of new data sources. This article begins with an overview of this transition, and argues that the spatial integration of information resources and the cross-disciplinary sharing of analysis and representation methodologies are important forces for the integration of scientific and artistic expression, and that they draw on core concepts in spatial (and spatio-temporal) thinking. We do not suggest that this is akin to prior concepts of unified knowledge systems, but we do maintain that the boundaries to knowledge transfer are disintegrating and that our abilities in problem solving for purposes of artistic expression and scientific development are enhanced through spatial perspectives. Moreover, approaches to education at all levels must recognize the need to impart proficiency in the critical and efficient application of these fundamental spatial concepts, if students and researchers are to make use of expanding access to a broadening range of spatialized information and data processing technologies.

More Than Just Chemistry: The Impact of a Collaborative Participant Structure on Student Perceptions of Science

NASA Astrophysics Data System (ADS)

Patchen, Terri; Smithenry, Dennis W.

2015-02-01

Researchers have theorized that integrating authentic science activities into classrooms will help students learn how working scientists collaboratively construct knowledge, but few empirical studies have examined students' experiences with these types of activities. Utilizing data from a comparative, mixed-methods study, we considered how integrating a complex, collaborative participant structure into a secondary school chemistry curriculum shapes students' perceptions of what constitutes "science." We found that the implementation of this participant structure expanded student perceptions of chemistry learning beyond the typical focus on science content knowledge to include the acquisition of collaboration skills. This support for the collaborative construction of knowledge, in addition to the appropriation of scientific content, establishes the conditions for what science educators and scientists say they want: students who can work together to solve science problems. Radical shifts towards such collaborative participant structures are necessary if we are to modify student perceptions of science and science classrooms in ways that are aligned with recent calls for science education reform.

Cancer Prevention for the Next Generation

2015-01-01

Given the continued growth in the number of persons with cancer in the United States, the primary prevention of cancer remains an urgent public health priority. As the field of cancer prevention continues to mature and scientific knowledge evolves, it is imperative to challenge the status quo and embrace new approaches to cancer prevention. In this commentary, we summarize recent trends and some of the scientific advances that have been made over the past few decades regarding the complex process of cancer development and the interaction of individual and social risk factors. We examine some of the assumptions and terminology that have characterized cancer prevention approaches for more than a quarter century and the impact of these assumptions and our use of terminology. We propose that it is possible for today’s youth to experience lower cancer incidence rates as adults compared with previous generations. To accomplish this goal, a more transdisciplinary and multifaceted approach is needed, adapted as appropriate for different populations and stages of life. The greatest improvements in cancer prevention may occur as a result of innovative, multilevel interventions that build on the expanding scientific evidence base. PMID:23601606

From Folklore to Scientific Evidence: Breast-Feeding and Wet-Nursing in Islam and the Case of Non-Puerperal Lactation

PubMed Central

Moran, Lia; Gilad, Jacob

2007-01-01

Breast-feeding practice has an important medical and socio-cultural role. It has many anthropological aspects concerning the “power structures” that find their expression in breast-feeding and the practices that formed around it, both socially, scientifically, and legally-speaking. Breast-feeding has been given much attention by religions and taboos, folklore, and misconception abound around it making it a topic of genuine curiosity. This paper aims at expanding the spectrum of folklore associated with breast-feeding. The paper deals with historical, religious, and folkloristic aspects of breast-feeding, especially wet-nursing, in Islam and focuses on an intriguing Islamic tale on breast-feeding - lactation by non-pregnant women (or non-puerperal lactation). Apparently, accounts of non-puerperal lactation are not restricted to Islam but have been documented in various societies and religions throughout centuries. Two medical situations - hyperprolactinemia and induced lactation, appear as possible explanations for this phenomenon. This serves as an excellent example for the value of utilizing contemporary scientific knowledge in order to elucidate the origin, anthropology and evolvement of ancient myth and superstition.

Inherited disorders of voltage-gated sodium channels

PubMed Central

George, Alfred L.

2005-01-01

A variety of inherited human disorders affecting skeletal muscle contraction, heart rhythm, and nervous system function have been traced to mutations in genes encoding voltage-gated sodium channels. Clinical severity among these conditions ranges from mild or even latent disease to life-threatening or incapacitating conditions. The sodium channelopathies were among the first recognized ion channel diseases and continue to attract widespread clinical and scientific interest. An expanding knowledge base has substantially advanced our understanding of structure-function and genotype-phenotype relationships for voltage-gated sodium channels and provided new insights into the pathophysiological basis for common diseases such as cardiac arrhythmias and epilepsy.

Over the years, clinical trials with their structured treatment plans and multicenter involvement have been instrumental in developing new treatments and establishing standard of care therapy. While clinical trials strive to advance medical knowledge, they provide scientifically sound, state of the art care and their use should be increased. The Brain Tumor Cooperative Group, one such NCI-sponsored cooperative group, has been the primary group for the treatment of malignant gliomas. As the field of neuro-oncology expands, the neuroscience nurse needs to develop an understanding of clinical trials and their operation. The nurse is in an optimal position to support medical research and the research participant.

With the recognized need for health systems' improvements in the circumpolar and indigenous context, there has been a call to expand the research agenda across all sectors influencing wellness and to recognize academic and indigenous knowledge through the research process. Despite being recognized as a distinct body of knowledge in international forums and across indigenous groups, examples of methods and theories based on indigenous knowledge are not well documented in academic texts or peer-reviewed literature on health systems. This paper describes the use of a consensus-based, mixed method with indigenous knowledge by an experienced group of researchers and indigenous knowledge holders who collaborated on a study that explored indigenous values underlying health systems stewardship. The method is built on the principles of Etuaptmumk or two-eyed seeing, which aim to respond to and resolve the inherent conflicts between indigenous ways of knowing and the scientific inquiry that informs the evidence base in health care. Mixed methods' frameworks appear to provide a framing suitable for research questions that require data from indigenous knowledge sources and western knowledge. The nominal consensus method, as a western paradigm, was found to be responsive to embedding of indigenous knowledge and allowed space to express multiple perspectives and reach consensus on the question at hand. Further utilization and critical evaluation of this mixed methodology with indigenous knowledge are required.

Butina, Michelle; Leibach, Elizabeth Kenimer

2014-01-01

A review of professional literature was conducted to examine the history of the education of medical laboratory practitioners. This comprehensive review included historical educational milestones from World War II to present day. During this time period the standard of two years of college required for matriculation into a medical technology program increased to four years. Critical thinking skills promoted in the educational model and applied in practice expanded from an analytic and psychomotor orientation to include those requiring extensive situational interpretation and negotiation. By the end of the twentieth century, the clinical laboratory had experienced significant scientific and technologic transformations necessitating greatly expanded roles for the medical laboratory practitioner. Though the educational requirements and education model have changed minimally since the 1970's, the knowledge and skills required for the next generation of medical laboratory practitioners continue to escalate. The second decade of the 21st century portends a transformation in medical laboratory practitioner education commensurate with the rapid advancement of science, technology, communications, and the precepts of evidence-based practice.

Nature of Science, Scientific Inquiry, and Socio-Scientific Issues Arising from Genetics: A Pathway to Developing a Scientifically Literate Citizenry

NASA Astrophysics Data System (ADS)

Lederman, Norman G.; Antink, Allison; Bartos, Stephen

2014-02-01

The primary focus of this article is to illustrate how teachers can use contemporary socio-scientific issues to teach students about nature of scientific knowledge as well as address the science subject matter embedded in the issues. The article provides an initial discussion about the various aspects of nature of scientific knowledge that are addressed. It is important to remember that the aspects of nature of scientific knowledge are not considered to be a comprehensive list, but rather a set of important ideas for adolescent students to learn about scientific knowledge. These ideas have been advocated as important for secondary students by numerous reform documents internationally. Then, several examples are used to illustrate how genetically based socio-scientific issues can be used by teachers to improve students' understandings of the discussed aspects of nature of scientific knowledge.

Citizen science for water quality monitoring: Data implications of citizen perspectives.

Jollymore, Ashlee; Haines, Morgan J; Satterfield, Terre; Johnson, Mark S

2017-09-15

Citizen science, where citizens play an active role in the scientific process, is increasingly used to expand the reach and scope of scientific research while also achieving engagement and educational goals. Despite the emergence of studies exploring data outcomes of citizen science, the process and experience of engaging with citizens and citizen-lead groups through participatory science is less explored. This includes how citizen perspectives alter data outcomes, a critical upshot given prevalent mistrust of citizen versus scientist data. This study uses a citizen science campaign investigating watershed impacts on water quality to interrogate the nature and implications of citizen involvement in producing scientifically and societally relevant data. Data representing scientific outcomes are presented alongside a series of vignettes that offer context regarding how, why, and where citizens engaged with the project. From these vignettes, six specific lessons are examined towards understanding how integration of citizen participation alters data outcomes relative to 'professional' science. In particular, elements of participant social identity (e.g., their motivation for participation), and contextual knowledge (e.g., of the research program itself) can shape participation and resulting data outcomes. Such scientific outcomes are particularly relevant given continued concerns regarding the quality of citizen data, which could hinder scientific acceptance of citizen sciences. Importantly, the potential for meaningful engagement with citizen and participants within citizen groups - given significant capacity within the community - represents a substantial and under-realized opportunity.

In 2000 The Ohio Academy of Science published its definition of "Science." Response to this definition led the Academy to produce a position paper entitled What is Science? The Academy officially adopted the position paper version of What is Science?, http: //www.ohiosci.org/ Whatisscience.pdf, at the April 2004 Ohio Academy of Science Annual Meeting. Response to this fact sheet demonstrated a need to further expand this document. Thus, this expanded version builds on the April 2004 position paper, What is Science? This paper clarifies what is science, the scientific method, a scientific hypothesis, a scientific theory, the importance of science, and what is not science.

Serving California's Science and Governance Needs through Crisis-driven Collaborations

NASA Astrophysics Data System (ADS)

Bernacchi, L.

2015-12-01

Due to its magnitude, the ongoing drought in California (USA) serves as an experimental space for innovative resource management and will define responses to predicted widespread drought. Due to the magnitude of its effect on humans and natural ecosystems and the water resources on which they depend, governmental programs are granting support to scientifically-valid, locally-produced solutions to water scarcity. Concurrently, University of California Water (UC Water) Security and Sustainability Research Initiative is focused on strategic research to build the knowledge base for better water resources management. This paper examines how a team of transdisciplinary scientists are engaged in water governance and information, providing examples of actionable research successfully implemented by decision makers. From a sociology of science perspective, UC Water scientists were interviewed about their engagement practices with California water decision makers. Their "co-production of knowledge" relationships produce effective responses to climatic, landcover and population changes by expanding from singularly information-based, unidirectional communication to governance-relevant, co-constructed knowledge and wisdom. This is accomplished by serving on decision making organizational boards and developing information in a productive format. The perceived crisis of California's drought is an important impetus in cross-sector collaborations, and in combination with governance and institution parameters, defines the inquiry and decision space. We conclude by describing a process of clear problem-solution definition made possible through transparent communication, salient and credible information, and relevant tools and techniques for interpreting scientific findings.

Scientific Research for Integrated Solutions to Community Challenges: The Thriving Earth Exchange (TEX) Approach

There is tremendous unmet and sometimes unrealized need for Earth and space science (ESS) expertise as part of civic decisions and local planning for climate change, natural hazards and natural resources. The Thriving Earth Exchange (TEX) helps AGU contribute that expertise to humanity in respectful, integrated ways. TEX brings ESS scientists together with local communities tackling issues of climate change, natural hazards and natural resources to co-design solutions that equitably integrate both scientific and community knowledge. To achieve this ambitious goal, TEX is partnering with organizations that are respected by and knowledgeable about communities both in the United States and internationally. Such partnerships include Rockefeller's 100 Resilient Cities Initiative, ICLEI USA, MIT's Climate Colab, among others. TEX works with these partners to approach communities who are ready to or already addressing ESS related issues. With partners, we help the communities define their goals, develop specific projects, and connect with relevant and helpful ESS scientists. We will also show how we help scientists and community leaders work productively together, and the tools we bring to support their innovation. It will highlight international examples, such as in the Pamir Mountains of Afghanistan-Tajikistan, Sri Lanka, and Ethiopia, and provide concrete examples of how these initiatives are helping TEX further expand the frontiers of collaborative research.

Debate on global warming as a socio-scientific issue: science teaching towards political literacy

dos Santos, Wildson Luiz Pereira

2014-09-01

The focus of this response to the original article by Tom G. H. Bryce and Stephen P. Day (Cult Stud Sci Educ. doi: 10.1007/s11422-012-9407-1, 2013) is the use of empirical data to illustrate and expand the understanding of key points of their argument. Initially, I seek to discuss possible answers to the three questions posed by the authors related to: (1) the concerns to be addressed and the scientific knowledge to be taken into account in the climate change debate, (2) the attention to be paid to perspectives taken by "alarmists" and "deniers," and (3) the approaches to be used to conduct controversial global warming debate. In this discussion, I seek to contribute to the debate proposed by the original paper, illustrating various points commented on by the authors and expanding to other possibilities, which highlight the importance of political issues in the debate. Therefore, I argue that socio-political issues must be taken into account when I aim for a scientific literacy that can enhance students' political education. Likewise, I extend the debate presented in the original article, emphasizing the attention that should be paid to these aspects and approaching science education from a critical perspective. Highlighting only the confirmation bias without considering political implications of the debate can induce a reductionist and empiricist view of science, detached from the political power that acts on scientific activity. In conclusion, I support the idea that for a critical science education, the discussion of political issues should be involved in any controversial debate, a view, which goes beyond the confirmation bias proposed by Bryce and Day for the global warming debate. These issues are indeed vital and science teachers should take them into account when preparing their lessons for the debate on climate change.

The influence of capture-recapture methodology on the evolution of the North American Bird Banding Program

Capture-recapture methodology has advanced greatly in the last twenty years and is now a major factor driving the continuing evolution of the North American bird banding program. Bird banding studies are becoming more scientific with improved study designs and analytical procedures. Researchers and managers are gaining more reliable knowledge which in turn betters the conservation of migratory birds. The advances in capture-recapture methodology have benefited gamebird studies primarily, but nongame bird studies will benefit similarly as they expand greatly in the next decade. Further theoretical development of capture-recapture methodology should be encouraged, and, to maximize benefits of the methodology, work on practical applications should be increased.

Twitter is a tool for physicians to increase engagement of learners and the public, share scientific information, crowdsource new ideas, conduct, discuss and challenge emerging research, pursue professional development and continuing medical education, expand networks around specialized topics and provide moral support to colleagues. However, new users or skeptics may well be wary of its potential pitfalls. The aims of this commentary are to discuss the potential advantages of the Twitter platform for dialogue among physicians, to explore the barriers to accurate and high-quality healthcare discourse and, finally, to recommend potential safeguards physicians may employ against these threats in order to participate productively.

[Indigenous medical assistance in Madagascar (1898-1950)].

PubMed

Merlin, J; Mafart, B; Triaud, J L

2003-01-01

The foundations of local health services in Madagascar were laid when the island was taken over by the French in 1896. Medical care was a major priority for the first colonial governor named General Galliéni. Local health services expanded greatly from 1896 to 1950 thanks notably to institutions such as the Tananarive Medical School and Pasteur Institute. These services played a crucial role in the fight against smallpox and bubonic plague. However they were also used for political purposes by both colonial and independent governments. In sum the history of local health services in Madagascar can be described as a battle between political power and scientific knowledge. The overall result is positive for some and controversial for others.

This study takes on a relational and situated perspective to understand the relationship between scientific knowledge and fortune-telling. Measures included socio-demographic characteristics, knowledge of scientific facts and methods, and fortune-telling beliefs and practices. A sample of 1863 adults was drawn from a population of Taiwanese citizens using the method of probability proportional to size. The findings showed that knowledge of scientific methods was negatively associated with fortune-telling beliefs. However, knowledge of scientific facts was, by and large, positively associated with engagement in fortune-telling practices, a phenomenon known as cognitive polyphasia. This study does not imply that science communication or education have no effect on promoting scientific knowledge; rather, it hopes to encourage researchers and practitioners to use a culturally sensitive lens to rethink the role of science in society and its relationship with other forms of knowledge and belief. © The Author(s) 2014.

Phytoplankton growth in the Bay of Biscay intensified in early May, 2013, painting the deep blue waters with huge swirls of jewel-tone colors that were brilliantly visible from space. The Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA’s Terra satellite captured this true-color image on May 4, 2013. Each year, typically from March through April, such blooms occur in the Bay of Biscay. By May, however, conditions are not as favorable and the blooms tend to fade, then disappear. This bloom is expanding in early May this year, but will likely begin to diminish soon. Credit: NASA/GSFC/Jeff Schmaltz/MODIS Land Rapid Response Team NASA image use policy.

The international radio astronomy initiative known as the Square Kilometre Array is a cutting-edge science project, aimed atdramatically expanding our vision and understanding of the Universe. The $2billion+ international project is being shared between Southern Africa and Australia. The Australian component, centred in the Murchison region of Western Australia, is based upon collaboration with Aboriginal communities. A collaborative project called "Ilgarijiri- Things Belonging to the Sky" shared scientific and Aboriginal knowledge of the night sky. Through a series of collaborative meetings and knowledge sharing, the Ilgarijiri project developed and showcased Aboriginal knowledge of the night sky, via an international touring Aboriginal art exhibition, in Australia, South Africa, the USA and Europe. The Aboriginal art exhibition presents Aboriginal stories relating to the night sky, which prominently feature the 'Seven Sisters' and the 'Emu', as well as the collaborative experience with radio astronomers. The success of the Ilgarijiri collaborative project is based upon several principles, which can help to inform and guide future cultural collaborative projects.

In May, members of the microplastic research community met in the Biosphere Reserve of Lanzarote, Canary Islands, Spain for the first international conference on microplastics, MICRO 2016: "Fate and Impact of Microplastics in Marine Ecosystems: From the Coastline to the Open Sea." During the conference, members of the scientific committee and organizing board launched a collaborative process culminating in the creation of the Lanzarote Declaration, released June 21st (see the link for full text: micro2016.sciencesconf.org). With growing evidence of the environmental consequences and potential threats to human health posed by microplastics, the statement is clear: as long as we continue increasing plastic production and consumption, we will continue increasing its environmental impacts and as the environmental impacts increase and intensify, it will not be surprising to see the consequences for humans reflect similar trends. This leaves us with a major question: How should we move from here, from knowledge to action? Clearly, as microplastics continue accumulating in the environment, the scientific community must join forces to expand our knowledge horizons. Doing so requires collaboration and cooperation, at all scales, from local to global, spanning sectors and disciplines, to improve knowledge, education and outreach efforts. This should not delay actions. With the Lanzarote Declaration, we recognize our responsibility as individuals to change our behaviors related to plastic production and consumption, and to inform others of the social, cultural, economic and environmental implications. The MICRO community is engaging the challenge to work collaboratively. This abstract is one of the milestones from the road to MICRO 2018, a forum to share available knowledge, fill in gaps, and establish new commitments for implementing solutions.

Read, retrieve, connect and use: An intervention strategy for science and scientific literacy

NASA Astrophysics Data System (ADS)

Monahan, Kerryane T.

American students underachieve on local, state, national, and international assessments of science. Student performance on standardized assessments has driven numerous educational reforms including No Child Left Behind and Race to the Top with a resulting increased focus on student achievement. Local districts and schools struggle with how to improve student achievement in order to meet the requirements of state and federal legislation. International and national government officials extoll the value of science in driving the economic prosperity of a nation adding increased pressure to improve science scores in the United States. Moreover, to be effective decision-makers personally and within a democracy, citizens must be scientifically literate. Read, Retrieve, Connect and Use (RRCU) is an instructional strategy that combined state biology content standards, with the new Common Core Standards for Literacy in Science through evidenced-based literacy strategies recommended by the National Reading Panel. This study aimed to assess the efficacy of an intervention, RRCU to improve science content knowledge and literacy skills in Biology and Language Arts. The findings identified reading skill, as measured by FCAT Reading as predictive of Biology test scores indicating a close relationship between reading comprehension and the ability to learn and be assessed on science content knowledge. The data did not indicate RRCU was an effective means of improving student science content knowledge or literacy skills. However, teachers responded positively to the strategy as a means to reinforce content knowledge and support literacy skills. Future recommendations include improving the study design and expanding the use of the strategy to middle school to build a foundation of effective literacy skills students can use to cope with the depth and complexity of science content at the high school level.

Community Intelligence in Knowledge Curation: An Application to Managing Scientific Nomenclature

Harnessing community intelligence in knowledge curation bears significant promise in dealing with communication and education in the flood of scientific knowledge. As knowledge is accumulated at ever-faster rates, scientific nomenclature, a particular kind of knowledge, is concurrently generated in all kinds of fields. Since nomenclature is a system of terms used to name things in a particular discipline, accurate translation of scientific nomenclature in different languages is of critical importance, not only for communications and collaborations with English-speaking people, but also for knowledge dissemination among people in the non-English-speaking world, particularly young students and researchers. However, it lacks of accuracy and standardization when translating scientific nomenclature from English to other languages, especially for those languages that do not belong to the same language family as English. To address this issue, here we propose for the first time the application of community intelligence in scientific nomenclature management, namely, harnessing collective intelligence for translation of scientific nomenclature from English to other languages. As community intelligence applied to knowledge curation is primarily aided by wiki and Chinese is the native language for about one-fifth of the world’s population, we put the proposed application into practice, by developing a wiki-based English-to-Chinese Scientific Nomenclature Dictionary (ESND; http://esnd.big.ac.cn). ESND is a wiki-based, publicly editable and open-content platform, exploiting the whole power of the scientific community in collectively and collaboratively managing scientific nomenclature. Based on community curation, ESND is capable of achieving accurate, standard, and comprehensive scientific nomenclature, demonstrating a valuable application of community intelligence in knowledge curation.

To address this issue, here we propose for the first time the application of community intelligence in scientific nomenclature management, namely, harnessing collective intelligence for translation of scientific nomenclature from English to other languages. As community intelligence applied to knowledge curation is primarily aided by wiki and Chinese is the native language for about one-fifth of the world's population, we put the proposed application into practice, by developing a wiki-based English-to-Chinese Scientific Nomenclature Dictionary (ESND; http://esnd.big.ac.cn). ESND is a wiki-based, publicly editable and open-content platform, exploiting the whole power of the scientific community in collectively and collaboratively managing scientific nomenclature. Based on community curation, ESND is capable of achieving accurate, standard, and comprehensive scientific nomenclature, demonstrating a valuable application of community intelligence in knowledge curation.

This paper analyzes the effects of the co-authorship and bibliographic coupling networks on the citations received by scientific articles. It expands prior research that limited its focus on the position of co-authors and incorporates the effects of the use of knowledge sources within articles: references. By creating a network on the basis of shared references, we propose a way to understand whether an article bridges among extant strands of literature and infer the size of its research community and its embeddedness. Thus, we map onto the article – our unit of analysis – the metrics of authors' position in the co-authorship network and of the use of knowledge on which the scientific article is grounded. Specifically, we adopt centrality measures – degree, betweenneess, and closeness centrality – in the co-authorship network and degree, betweenness centrality and clustering coefficient in the bibliographic coupling and show their influence on the citations received in first two years after the year of publication. Findings show that authors' degree positively impacts citations. Also closeness centrality has a positive effect manifested only when the giant component is relevant. Author's betweenness centrality has instead a negative effect that persists until the giant component - largest component of the network in which all nodes can be linked by a path - is relevant. Moreover, articles that draw on fragmented strands of literature tend to be cited more, whereas the size of the scientific research community and the embeddedness of the article in a cohesive cluster of literature have no effect.

"A mission-driven discipline": the growth of conservation biology.

PubMed

Meine, Curt; Soulé, Michael; Noss, Reed E

2006-06-01

Conservation biology emerged in the mid-1980s, drawing on established disciplines and integrating them in pursuit of a coherent goal: the protection and perpetuation of the Earth's biological diversity. Opportunistic in its borrowing and application of knowledge, conservation biology had its roots within the established biological sciences and resource management disciplines but has continually incorporated insights from the empirical experience of resource managers, from the social sciences and humanities, and from diverse cultural sources. The Society for Conservation Biology (SCB) has represented the field's core constituency, while expanding that constituency in keeping with the field's integrative spirit. Conservation Biology has served as SCB's flagship publication, promoting research, dialog, debate, and application of the field's essential concepts. Over the last 20 years the field, SCB, and the journal have evolved to meet changing conservation needs, to explore gaps in our knowledge base, to incorporate new information from related fields, to build professional capacity, and to provide expanded opportunities for international participation. In turn, the field, SCB, and journal have prompted change in related fields, organizations, and publications. In its dedication to advancing the scientific foundations of biodiversity conservation and placing that science at the service of society in a world whose variety, wildness, and beauty we care for conservation biology represents both a continuation and radical reconfiguration of the traditional relationship between science and conservation.

Mapping the Sloan Digital Sky Survey's Global Impact

The scientific capacity of a country is essential in todayâ's increasingly globalized science and technology ecosystem. Scientific capacity has four increasingly advanced levels of capabilities: absorbing, applying, creating, and retaining scientific knowledge. Moving to a advanced level requires additional skills and training. For example, it requires more specialized skills to apply scientific knowledge than to absorb knowledge. Similarly, making new discoveries requires more knowledge than applying existing procedures. Research has shown the importance of addressing specific, local problems while tapping into globally available expertise and resources. Accessing scientific knowledge is the first step towards absorbing knowledge. Low-income countries have increased their access to scientific literature on the Internet, but to what extent has this access led to more advanced levels of scientific capacity? Interdisciplinary and international collaboration may hold the key to creating and retaining knowledge. For example, creative ideas tend to be associated with inspirations originated from a diverse range of perspectives On the other hand, not all collaborations are productive. Assessing global science and technology needs to address both successes and failures and reasons behind them.

Reconceptualizing the Nature of Science for Science Education

NASA Astrophysics Data System (ADS)

Dagher, Zoubeida R.; Erduran, Sibel

2016-03-01

Two fundamental questions about science are relevant for science educators: (a) What is the nature of science? and (b) what aspects of nature of science should be taught and learned? They are fundamental because they pertain to how science gets to be framed as a school subject and determines what aspects of it are worthy of inclusion in school science. This conceptual article re-examines extant notions of nature of science and proposes an expanded version of the Family Resemblance Approach (FRA), originally developed by Irzik and Nola (International handbook of research in history, philosophy and science teaching. Springer, Dordrecht, pp 999-1021, 2014) in which they view science as a cognitive-epistemic and as an institutional-social system. The conceptual basis of the expanded FRA is described and justified in this article based on a detailed account published elsewhere (Erduran and Dagher in Reconceptualizing the nature of science for science education: scientific knowledge, practices and other family categories. Springer, Dordrecht, 2014a). The expanded FRA provides a useful framework for organizing science curriculum and instruction and gives rise to generative visual tools that support the implementation of a richer understanding of and about science. The practical implications for this approach have been incorporated into analysis of curriculum policy documents, curriculum implementation resources, textbook analysis and teacher education settings.

The Interagency Arctic Research Policy Committee (IARPC) envisions a prosperous, sustainable, and healthy Arctic understood through innovative and collaborative research coordinated among Federal agencies and domestic and international partners. IARPC's approach is to harnesses the talent of the scientific and stakeholder community through Federally-run but broadly open collaboration teams, and an innovative website that expands the frontiers of collaborative research. The Obama Administration released the five-year Arctic Research Plan: FY2013-2017 in February 2013. The Plan focuses on advancing knowledge and sustainability of the Arctic by improving collaboration in seven priority research areas: sea ice and marine ecosystems, terrestrial ice and ecosystems, atmospheric studies, observing systems, regional climate models, human health studies, and adaptation tools for communities. From these seven research areas, 12 collaboration teams were formed to respond to the 145 milestones laid out in the Plan. The collaboration teams are charged with enhancing inter-institutional and interdisciplinary implementation of scientific research on local, regional, and circumpolar environmental and societal issues in the Arctic. The collaboration teams are co-chaired by Federal program managers, and, in some cases, external partners and are open to research and stakeholder communities. They meet on a regular basis by web- or teleconference to inform one another about ongoing and planned programs and new research results, as well as to inventory existing programs, identify gaps in knowledge and research, and address and implement the Plan's milestones. In-between meetings, team members communicate via our innovative, user-driven, collaboration website. Members share information about their research activities by posting updates, uploading documents, and including events on our calendar, and entering into dialogue about their research activities. Conversations taking place on the website are open to any other member, enabling new talent to enter into conversations and collaborations to form.

Advances in measurement technology and data collection is the database gets larger. Large databases require powerful tools for analysis data. Iterative process of acquiring knowledge from information obtained from data processing is done in various forms in all scientific fields. However, when the data volume large, and many of the problems the Traditional methods cannot respond. in the recent years, use of databases in various scientific fields, especially atmospheric databases in climatology expanded. in addition, increases in the amount of data generated by the climate models is a challenge for analysis of it for extraction of hidden pattern and knowledge. The approach to this problem has been made in recent years uses the process of knowledge discovery and data mining techniques with the use of the concepts of machine learning, artificial intelligence and expert (professional) systems is overall performance. Data manning is analytically process for manning in massive volume data. The ultimate goal of data mining is access to information and finally knowledge. climatology is a part of science that uses variety and massive volume data. Goal of the climate data manning is Achieve to information from variety and massive atmospheric and non-atmospheric data. in fact, Knowledge Discovery performs these activities in a logical and predetermined and almost automatic process.

Investigating the role of content knowledge, argumentation, and situational features to support genetics literacy

NASA Astrophysics Data System (ADS)

Shea, Nicole Anne

Science curriculum is often used as a means to train students as future scientists with less emphasis placed on preparing students to reason about issues they may encounter in their daily lives (Feinstein, Allen, & Jenkins, 2013; Roth & Barton, 2004). The general public is required to think scientifically to some degree throughout their life and often across a variety of issues. From an empirical standpoint, we do not have a robust understanding of what scientific knowledge the public finds useful for reasoning about socio-scientific issues in their everyday lives (Feinstein, 2011). We also know very little about how the situational features of an issue influences reasoning strategy (i.e., the use of knowledge to generate arguments). Rapid advances in science - particularly in genetics - increasingly challenge the public to reason about socio-scientific issues. This raises questions about the public's ability to participate knowledgeably in socio-scientific debates, and to provide informed consent for a variety of novel scientific procedures. This dissertation aims to answer the questions: How do individuals use their genetic content knowledge to reason about authentic issues they may encounter in their daily lives? Individuals' scientific knowledge is a critical aspect of scientific literacy, but what scientific literacy looks like in practice as individuals use their content knowledge to reason about issues comprised of different situational features is still unclear. The purpose of this dissertation is to explore what knowledge is actually used by individuals to generate and support arguments about a variety of socio-scientific issues, and how the features of those issues influences reasoning strategy. Three studies were conducted to answer questions reflecting this purpose. Findings from this dissertation provide important insights into what scientific literacy looks like in practice.

Most reports of scientific misconduct have been focused on principal investigators and other scientists (e.g., biostatisticians) involved in the research enterprise. However, by virtue of their position, research coordinators are often closest to the research field where much of misconduct occurs. The purpose of this study was to describe research coordinators' experiences with scientific misconduct in their clinical environment. The descriptive design was embedded in a larger cross-sectional national survey. A total of 266 respondents, predominately registered nurses, who answered "yes" to having firsthand knowledge of scientific misconduct in the past year, provided open-ended question responses. Content analysis was conducted by the research team, ensuring agreement of core categories and subcategories of misconduct. Research coordinators most commonly learned about misconduct via firsthand witness of the event, with the principal investigator being the person most commonly identified as the responsible party. Five major categories of misconduct were identified: protocol violations, consent violations, fabrication, falsification, and financial conflict of interest. In 70% of cases, the misconduct was reported. In most instances where misconduct was reported, some action was taken. However, in approximately 14% of cases, no action or investigation ensued; in 6.5% of cases, the coordinator was fired or he or she resigned. This study demonstrates the need to expand definitions of scientific misconduct beyond fabrication, falsification, and plagiarism to include other practices. The importance of the ethical climate in the institution in ensuring a safe environment to report and an environment where evidence is reviewed cannot be overlooked.

2009-04-01

In today's Information Age, an effective cyber-infrastructure and Internet access underpins development and human welfare by strengthening education and training, expanding science, technology and innovation capability, opening up collaboration opportunities with the rest of the world, and generating the knowledge base for decision-making. Poor Internet connectivity prevents many countries in Africa, especially Sub-Saharan ones, from taking advantage of these opportunities. There are many initiatives from local, governmental, African, European and international organisations to promote, survey and fund networking. The eGY (electronic Geophysical Year) and Sharing Knowledge Foundation initiatives are based on African scientific communities, and are complementary of other initiatives. Their bottom-up role is twofold: firstly to motivate and support the scientists in each country (1) to ask their government or organisations for a better Internet for research and for education and (2) to organize themselves to welcome new technologies, secondly to promote a better cyber-infrastructure for their universities towards international organisations. In 2007 during the IHY workshop that gathered African scientists from 20 countries eGY provided the results of the questionnaire sent to all the participants to describe the status of internet in the Universities and Research institutes. Then recommendations were written. In 2007 Sharing the knowledge foundation organized a meeting devoted to internet and Grids in Africa. The participants, scientists, industrialists and members of NGO originating from 14 countries wrote also recommendations. In 2009 the presentation in this session of R.L.A Cottrell and U. Kalim will provide an overview of the evolution of the networking. In parallel to the improvement of internet the development of scientific collaboration among African countries and with Europe by using ICT was considered as an essential point. This presentation will be focused on the recommendations, different achievements and plans (see presentation in this section by V. Ardizzone et al.) .

School personnel may lack knowledge of diabetes and be unprepared to address the needs of students with type 1 diabetes. This project evaluated the effectiveness of a type 1 diabetes education program for school personnel on increasing knowledge of diabetes and confidence in caring for students with diabetes. Two types of diabetes education programs were created for school personnel. The basic program provided a 60-minute overview of diabetes. The expanded program, intended for volunteer health aides, provided participants with a more in-depth overview of diabetes during a 180-minute session, including demonstrations of how to assist students with insulin injections. Instruments were created to assess changes in diabetes-related knowledge and confidence in caring for students. Separate knowledge instruments were created for the basic and expanded programs. Knowledge instruments were administered before and after delivery of the education programs to both groups. Confidence instruments were administered before and after for persons completing the expanded program. A total of 81 school personnel participated in the basic (N = 44) or expanded programs (N = 37). Overall knowledge regarding diabetes significantly increased in both the basic and expanded programs from baseline (p < .001). Confidence in caring for students with diabetes also increased from pretest to posttest, both for overall confidence and each individual item (p < .001). Educational programs offered for school personnel can lead to increased knowledge and increased confidence in caring for students with diabetes, which may assist school personnel in addressing the needs of students with diabetes. © 2012, American School Health Association.

Playing with Science: Using Interactive Games to Improve Public Engagement

NASA Astrophysics Data System (ADS)

Unger, M.; Besser, N.

2015-12-01

The challenge of communicating science in an accurate, concise, and engaging way has never been more important. While much focus has been put on how scientific information gets delivered, perhaps less value has been put on what the public can communicate back to science. Imparting scientific knowledge to the public in one direction, however successfully done, could be called "transmission." It's not until the public responds that you have "communication," or maybe a better word would be "conversation." The National Center for Atmospheric Research (NCAR) has been working on a project for use in its educational visitor center that not only attempts to engage the public with concise, accurate scientific information, but also to help the public respond, in order to create a communicative circuit. Using an interactive game platform, visitors can immerse themselves in a voyage of scientific discovery by choosing a character and building a story line based on multiple selections, a version of a "build your own adventure" experience. We are exploring ways to capture data from these interactions in order to inform additional program development based on areas of greatest interest to the public. The game could thus be used to update existing exhibits so they better reflect those areas of interest, making them more relevant and engaging to visitors, and expanding opportunities for dialogue between science centers and members of the public.

Continuous Enhancement of Science Teachers' Knowledge and Skills through Scientific Lecturing.

Azevedo, Maria-Manuel; Duarte, Sofia

2018-01-01

Due to their importance in transmitting knowledge, teachers can play a crucial role in students' scientific literacy acquisition and motivation to respond to ongoing and future economic and societal challenges. However, to conduct this task effectively, teachers need to continuously improve their knowledge, and for that, a periodic update is mandatory for actualization of scientific knowledge and skills. This work is based on the outcomes of an educational study implemented with science teachers from Portuguese Basic and Secondary schools. We evaluated the effectiveness of a training activity consisting of lectures covering environmental and health sciences conducted by scientists/academic teachers. The outcomes of this educational study were evaluated using a survey with several questions about environmental and health scientific topics. Responses to the survey were analyzed before and after the implementation of the scientific lectures. Our results showed that Basic and Secondary schools teachers' knowledge was greatly improved after the lectures. The teachers under training felt that these scientific lectures have positively impacted their current knowledge and awareness on several up-to-date scientific topics, as well as their teaching methods. This study emphasizes the importance of continuing teacher education concerning knowledge and awareness about health and environmental education.

Epistemic agency in an environmental sciences watershed investigation fostered by digital photography

Zimmerman, Heather Toomey; Weible, Jennifer L.

2018-05-01

This collective case study investigates the role of digital photography to support high school students' engagement in science inquiry practices during a three-week environmental sciences unit. The study's theoretical framework brings together research from digital photography, participation in environmental science practices, and epistemic agency. Data analysed include field notes and video transcripts from two groups of learners (n = 19) that focus on how high school students used digital photography during their participation in two distinct environmental monitoring practices: stream mapping and macroinvertebrate identification. Our study resulted in two findings related to the role of digital photography where students developed knowledge as they engaged in environmental monitoring inquiry practices. First, we found that digital photography was integral to the youths' epistemic agency (defined as their confidence that they could build knowledge related to science in their community) as they engaged in data collection, documenting environmental monitoring procedures, and sharing data in the classroom. Based this finding, an implication of our work is a refined view of the role of digital photography in environmental sciences education where the use of photography enhances epistemic agency in inquiry-based activities. Second, we found that the youths innovated a use of digital photography to foster a recognition that they were capable and competent in scientific procedures during a streamside study. Based on this finding, we offer a theoretical implication that expands the construct of epistemic agency; we posit that epistemic agency includes a subcomponent where the students purposefully formulate an external recognition as producers of scientific knowledge.

Power and knowledge in psychiatry and the troubling case of Dr Osheroff.

PubMed

Robertson, Michael

2005-12-01

To consider the state of knowledge in psychiatry with reference to the 'Osheroff debate' about the treatment of depression. A review of the key philosophical issues regarding the nature of knowledge applied to the Osheroff case. There is an apparent dichotomy between knowledge derived from a reductionist scientific method, as manifest in evidence-based medicine, and that of a narrative form of knowledge derived from clinical experience. The Focauldian notion of knowledge/power and knowledge as discourse suggests that scientific knowledge dominates over narrative knowledge in psychiatry. The implication of this applied to the Osheroff case is the potential annihilation of all forms of knowledge other than science. Knowledge in psychiatry is a pluralist, rather than singularly scientific enterprise. In the Osheroff case, the potential for scientific knowledge to abolish other forms of knowledge posed a serious threat of weakening the profession. In the light of the current debate about best practice, there is a need for reconsideration of the implications of Osheroff.

Constructive Use of Authoritative Sources in Science Meaning-making

NASA Astrophysics Data System (ADS)

Yeo, Jennifer; Chee Tan, Seng

2010-09-01

Researchers are skeptical about the role of authoritative sources of information in a constructivist learning environment for fear of usurping students' critical thinking. Taking a social semiotics perspective in this study, authoritative sources are regarded as inscriptions of cultural artifacts, and science learning involves meaning-making of these cultural artifacts. In studying the meaning-making process of a group of students doing problem-based learning (PBL), our findings show that authoritative sources played an important role in deepening and expanding students' scientific knowledge. We also found that constructive use of authoritative sources involves interpretation of meaning in context. This structural coupling of authoritative sources and context for meaningful sense-making has to be taken into consideration in the design of learning environment.

Living With Earthquakes in the Pacific Northwest: A Survivor's Guide, 2nd edition

Hutton, Kate

In 1995, Robert S.Yeats found himself teaching a core curriculum class at Oregon State University for undergraduate nonscience majors, linking recent discoveries on the earthquake hazard in the Pacific Northwest to societal response to those hazards. The notes for that course evolved into the first edition of this book, published in 1998. In 2001, he published a similar book, Living With Earthquakes in California: A Survivors Guide (Oregon State University Press).Recent earthquakes, such as the 2001 Nisqually Mw6.8, discoveries, and new techniques in paleoseismology plus changes in public policy decisions, quickly outdated the first Pacific Northwest edition. This is especially true with the Cascadia Subduction Zone and crustal faults, where our knowledge expands with every scientific meeting.

"But my doctor recommended pot": medical marijuana and the patient-physician relationship.

PubMed

Nussbaum, Abraham M; Boyer, Jonathan A; Kondrad, Elin C

2011-11-01

As the use of medical marijuana expands, it is important to consider its implications for the patient-physician relationship. In Colorado, a small cohort of physicians is recommending marijuana, with 15 physicians registering 49% of all medical marijuana patients and a single physician registering 10% of all patients. Together, they have registered more than 2% of the state to use medical marijuana in the last three years. We are concerned that this dramatic expansion is occurring in a setting rife with conflicts of interest despite insufficient scientific knowledge about marijuana. This system diminishes the patient-physician relationship to the recommendation of a single substance while unburdening physicians of their usual responsibilities to the welfare of their patients.

Surrogacy in modern obstetric practice.

Burrell, Celia; Edozien, Leroy C

2014-10-01

Surrogacy is rising in profile and prevalence, which means that perinatal care providers face an increasing likelihood of encountering a case in their clinical practice. Rapidly expanding scientific knowledge (for example, fetal programming) and technological advances (for example, prenatal screening and diagnosis) pose challenges in the management of the surrogate mother; in particular, they could exacerbate conflict between the interests of the baby, the surrogate mother, and the intending parent(s). Navigating these often-tranquil-but-sometimes-stormy waters is facilitated if perinatal care providers are aware of the relevant ethical, legal, and service delivery issues. This paper describes the ethical and legal context of surrogacy, and outlines key clinical practice issues in management of the surrogate mother. Copyright © 2014 Elsevier Ltd. All rights reserved.

1997-01-01

This article proposes a new theoretical model for the effective management of intellectual capital in the health care industry. The evolution of knowledge-based resources as a value-adding characteristic of service industries coupled with mounting environmental pressures on health care necessitates the extension of current models of intellectual capital. Our theoretical model contains an expanded context linking its development to organizational learning theory and extends current theory by proposing a six-term archetype of organizational functioning built on flows of information. Further, our proposal offers a hierarchical dimension to intellectual capital and a method of scientific visualization for the measurement of intellectual capital. In conclusion, we offer some practical suggestions for future development, both for researchers and managers.

In the eighteenth century, a new genre of periodical literature appeared from Mexico City's presses that focused on disseminating scientific and medical knowledge to the colonial public. In part a natural extension of the healing manuals published for laypeople in previous centuries, the journals sought to introduce quantitative methods of environmental study and control and to expand the sphere of those residents who would take responsibility for their health. This article examines the content and format of these journals before turning to the response of urban publics during outbreaks of epidemics, when the broader social participation envisioned by enlightenment men of letters came to fruition through pasquinades and rumors conveying dissent, skepticism, and protest.

2018-01-01

Astrobiology is a discipline that is expanding its field of investigation not only in the natural sciences, but also in the social sciences. It is for this reason that the ethical aspects are progressively emphasized leading to a point where the whole field requires a specific handling. The appellation `astrobioethics' is now considered as not only relevant, but also a true issue for the future of Astrobiology. Astrobioethics is the subsection within astrobiology that is accountable for studying the moral implications of, for example, bringing humans to Mars, the Planetary Protection Policy, the social responsibility of the astrobiologist to society, etc. It is in this way that the present article outlines a path for astrobioethics, as being a fertile field of study and an opportunity to trade scientific knowledge in a transdisciplinary way.

Stroke is becoming more common in Germany as the population ages. Its long-term sequelae can be alleviated by early reperfusion in stroke units and by complication management and functional restoration in early-rehabilitation and rehabilitation centers. Selective review of the literature. Successful rehabilitation depends on systematic treatment by an interdisciplinary team of experienced specialists. In the area of functional restoration, there has been major progress in our understanding of the physiology of learning, relearning, training, and neuroenhancement. There have also been advances in supportive pharmacotherapy and robot technology. Well-organized acute and intermediate rehabilitation after stroke can provide patients with the best functional results attainable on the basis of our current scientific understanding. Further experimental and clinical studies will be needed to expand our knowledge and improve the efficacy of rehabilitation.

"Trees Live on Soil and Sunshine!"--Coexistence of Scientific and Alternative Conception of Tree Assimilation.

Thorn, Christine Johanna; Bissinger, Kerstin; Thorn, Simon; Bogner, Franz Xaver

2016-01-01

Successful learning is the integration of new knowledge into existing schemes, leading to an integrated and correct scientific conception. By contrast, the co-existence of scientific and alternative conceptions may indicate a fragmented knowledge profile. Every learner is unique and thus carries an individual set of preconceptions before classroom engagement due to prior experiences. Hence, instructors and teachers have to consider the heterogeneous knowledge profiles of their class when teaching. However, determinants of fragmented knowledge profiles are not well understood yet, which may hamper a development of adapted teaching schemes. We used a questionnaire-based approach to assess conceptual knowledge of tree assimilation and wood synthesis surveying 885 students of four educational levels: 6th graders, 10th graders, natural science freshmen and other academic studies freshmen. We analysed the influence of learner's characteristics such as educational level, age and sex on the coexistence of scientific and alternative conceptions. Within all subsamples well-known alternative conceptions regarding tree assimilation and wood synthesis coexisted with correct scientific ones. For example, students describe trees to be living on "soil and sunshine", representing scientific knowledge of photosynthesis mingled with an alternative conception of trees eating like animals. Fragmented knowledge profiles occurred in all subsamples, but our models showed that improved education and age foster knowledge integration. Sex had almost no influence on the existing scientific conceptions and evolution of knowledge integration. Consequently, complex biological issues such as tree assimilation and wood synthesis need specific support e.g. through repeated learning units in class- and seminar-rooms in order to help especially young students to handle and overcome common alternative conceptions and appropriately integrate scientific conceptions into their knowledge profile.

“Trees Live on Soil and Sunshine!”- Coexistence of Scientific and Alternative Conception of Tree Assimilation

Successful learning is the integration of new knowledge into existing schemes, leading to an integrated and correct scientific conception. By contrast, the co-existence of scientific and alternative conceptions may indicate a fragmented knowledge profile. Every learner is unique and thus carries an individual set of preconceptions before classroom engagement due to prior experiences. Hence, instructors and teachers have to consider the heterogeneous knowledge profiles of their class when teaching. However, determinants of fragmented knowledge profiles are not well understood yet, which may hamper a development of adapted teaching schemes. We used a questionnaire-based approach to assess conceptual knowledge of tree assimilation and wood synthesis surveying 885 students of four educational levels: 6th graders, 10th graders, natural science freshmen and other academic studies freshmen. We analysed the influence of learner’s characteristics such as educational level, age and sex on the coexistence of scientific and alternative conceptions. Within all subsamples well-known alternative conceptions regarding tree assimilation and wood synthesis coexisted with correct scientific ones. For example, students describe trees to be living on “soil and sunshine”, representing scientific knowledge of photosynthesis mingled with an alternative conception of trees eating like animals. Fragmented knowledge profiles occurred in all subsamples, but our models showed that improved education and age foster knowledge integration. Sex had almost no influence on the existing scientific conceptions and evolution of knowledge integration. Consequently, complex biological issues such as tree assimilation and wood synthesis need specific support e.g. through repeated learning units in class- and seminar-rooms in order to help especially young students to handle and overcome common alternative conceptions and appropriately integrate scientific conceptions into their knowledge profile.

Earthquake: Game-based learning for 21st century STEM education

NASA Astrophysics Data System (ADS)

Perkins, Abigail Christine

To play is to learn. A lack of empirical research within game-based learning literature, however, has hindered educational stakeholders to make informed decisions about game-based learning for 21st century STEM education. In this study, I modified a research and development (R&D) process to create a collaborative-competitive educational board game illuminating elements of earthquake engineering. I oriented instruction- and game-design principles around 21st century science education to adapt the R&D process to develop the educational game, Earthquake. As part of the R&D, I evaluated Earthquake for empirical evidence to support the claim that game-play results in student gains in critical thinking, scientific argumentation, metacognitive abilities, and earthquake engineering content knowledge. I developed Earthquake with the aid of eight focus groups with varying levels of expertise in science education research, teaching, administration, and game-design. After developing a functional prototype, I pilot-tested Earthquake with teacher-participants (n=14) who engaged in semi-structured interviews after their game-play. I analyzed teacher interviews with constant comparison methodology. I used teachers' comments and feedback from content knowledge experts to integrate game modifications, implementing results to improve Earthquake. I added player roles, simplified phrasing on cards, and produced an introductory video. I then administered the modified Earthquake game to two groups of high school student-participants (n = 6), who played twice. To seek evidence documenting support for my knowledge claim, I analyzed videotapes of students' game-play using a game-based learning checklist. My assessment of learning gains revealed increases in all categories of students' performance: critical thinking, metacognition, scientific argumentation, and earthquake engineering content knowledge acquisition. Players in both student-groups improved mostly in critical thinking, having doubled the number of exhibited instances of critical thinking between games. Players in the first group exhibited about a third more instances of metacognition between games, while players in the second group doubled such instances. Between games, players in both groups more than doubled the number of exhibited instances of using earthquake engineering content knowledge. The student-players expanded use of scientific argumentation for all game-based learning checklist categories. With empirical evidence, I conclude play and learning can connect for successful 21 st century STEM education.

Rethinking historical and cultural source of spontaneous mental models of water cycle: in the perspective of South Korea

2012-06-01

This review explores Ben-Zvi Assaraf, Eshach, Orion, and Alamour's paper titled "Cultural Differences and Students' Spontaneous Models of the Water Cycle: A Case Study of Jewish and Bedouin Children in Israel" by examining how the authors use the concept of spontaneous mental models to explain cultural knowledge source of Bedouin children's mental model of water compared to Jewish children's mental model of water in nature. My response to Ben-Zvi Assaraf et al.'s work expands upon their explanations of the Bedouin children's cultural knowledge source. Bedouin children's mental model is based on their culture, religion, place of living and everyday life practices related to water. I suggest a different knowledge source for spontaneous mental model of water in nature based on unique history and traditions of South Korea where people think of water in nature in different ways. This forum also addresses how western science dominates South Korean science curriculum and ways of assessing students' conceptual understanding of scientific concepts. Additionally I argue that western science curriculum models could diminish Korean students' understanding of natural world which are based on Korean cultural ways of thinking about the natural world. Finally, I also suggest two different ways of considering this unique knowledge source for a more culturally relevant teaching Earth system education.

Concept Formation in Scientific Knowledge Discovery from a Constructivist View

NASA Astrophysics Data System (ADS)

Peng, Wei; Gero, John S.

The central goal of scientific knowledge discovery is to learn cause-effect relationships among natural phenomena presented as variables and the consequences their interactions. Scientific knowledge is normally expressed as scientific taxonomies and qualitative and quantitative laws [1]. This type of knowledge represents intrinsic regularities of the observed phenomena that can be used to explain and predict behaviors of the phenomena. It is a generalization that is abstracted and externalized from a set of contexts and applicable to a broader scope. Scientific knowledge is a type of third-person knowledge, i.e., knowledge that independent of a specific enquirer. Artificial intelligence approaches, particularly data mining algorithms that are used to identify meaningful patterns from large data sets, are approaches that aim to facilitate the knowledge discovery process [2]. A broad spectrum of algorithms has been developed in addressing classification, associative learning, and clustering problems. However, their linkages to people who use them have not been adequately explored. Issues in relation to supporting the interpretation of the patterns, the application of prior knowledge to the data mining process and addressing user interactions remain challenges for building knowledge discovery tools [3]. As a consequence, scientists rely on their experience to formulate problems, evaluate hypotheses, reason about untraceable factors and derive new problems. This type of knowledge which they have developed during their career is called “first-person” knowledge. The formation of scientific knowledge (third-person knowledge) is highly influenced by the enquirer’s first-person knowledge construct, which is a result of his or her interactions with the environment. There have been attempts to craft automatic knowledge discovery tools but these systems are limited in their capabilities to handle the dynamics of personal experience. There are now trends in developing approaches to assist scientists applying their expertise to model formation, simulation, and prediction in various domains [4], [5]. On the other hand, first-person knowledge becomes third-person theory only if it proves general by evidence and is acknowledged by a scientific community. Researchers start to focus on building interactive cooperation platforms [1] to accommodate different views into the knowledge discovery process. There are some fundamental questions in relation to scientific knowledge development. What aremajor components for knowledge construction and how do people construct their knowledge? How is this personal construct assimilated and accommodated into a scientific paradigm? How can one design a computational system to facilitate these processes? This chapter does not attempt to answer all these questions but serves as a basis to foster thinking along this line. A brief literature review about how people develop their knowledge is carried out through a constructivist view. A hydrological modeling scenario is presented to elucidate the approach.

Ecosystem modeling applied to fisheries remains hampered by a lack of local information. Fishers' knowledge could fill this gap, improving participation in and the management of fisheries. The same fishing area was modeled using two approaches: based on fishers' knowledge and based on scientific information. For the former, the data was collected by interviews through the Delphi methodology, and for the latter, the data was gathered from the literature. Agreement between the attributes generated by the fishers' knowledge model and scientific model is discussed and explored, aiming to improve data availability, the ecosystem model, and fisheries management. The ecosystem attributes produced from the fishers' knowledge model were consistent with the ecosystem attributes produced by the scientific model, and elaborated using only the scientific data from literature. This study provides evidence that fishers' knowledge may suitably complement scientific data, and may improve the modeling tools for the research and management of fisheries.

2014-12-01

The new area of health system research requires a revision of the taxonomy of scientific knowledge that may facilitate a better understanding and representation of complex health phenomena in research discovery, corroboration and implementation. A position paper by an expert group following and iterative approach. 'Scientific evidence' should be differentiated from 'elicited knowledge' of experts and users, and this latter typology should be described beyond the traditional qualitative framework. Within this context 'framing of scientific knowledge' (FSK) is defined as a group of studies of prior expert knowledge specifically aimed at generating formal scientific frames. To be distinguished from other unstructured frames, FSK must be explicit, standardized, based on the available evidence, agreed by a group of experts and subdued to the principles of commensurability, transparency for corroboration and transferability that characterize scientific research. A preliminary typology of scientific framing studies is presented. This typology includes, among others, health declarations, position papers, expert-based clinical guides, conceptual maps, classifications, expert-driven health atlases and expert-driven studies of costs and burden of illness. This grouping of expert-based studies constitutes a different kind of scientific knowledge and should be clearly differentiated from 'evidence' gathered from experimental and observational studies in health system research. © 2014 John Wiley & Sons, Ltd.

The importance of making scientific data more available can't be overstated. There is a wealth of useful scientific data available and demand for this data is only increasing; however, applying scientific data towards practical uses poses several technical challenges. These challenges can arise from difficulty in handling the data due largely to 1) the complexity, variety and volume of scientific data and 2) applying and operating the techniques and tools needed to visualize and analyze the data. As a result, the combined knowledge required to take advantage of these data requires highly specialized skill sets that in total, limit the ability of scientific data from being used in more practical day-to-day decision making activities. While these challenges are daunting, information technologies do exist that can help mitigate some of these issues. Many organizations for years have already been enjoying the benefits of modern service oriented architectures (SOAs) for everyday enterprise tasks. We can use this approach to modernize how we share and access our scientific data where much of the specialized tools and techniques needed to handle and present scientific data can be automated and executed by servers and done so in an appropriate way. We will discuss and show an approach for preparing file based scientific data (e.g. GRIB, netCDF) for use in standard based scientific web services. These scientific web services are able to encapsulate the logic needed to handle and describe scientific data through a variety of service types including, image, map, feature, geoprocessing, and their respective service methods. By combining these types of services and leveraging well-documented and modern web development APIs, we can afford to focus our attention on the design and development of user-friendly maps and apps. Our scenario will include developing online maps through these services by integrating various forecast data from the Climate Forecast System (CFSv2). This presentation showcases a collaboration between the National Oceanic and Atmospheric Administration's (NOAA) Climate.gov portal, Climate Prediction Center and Esri, Inc. on the implementation of the ArcGIS platform, which is aimed at helping modernize scientific data access through a service oriented architecture.

Twenty-first century science as a relational process: from eureka! to team science and a place for community psychology.

PubMed

Tebes, Jacob Kraemer; Thai, Nghi D; Matlin, Samantha L

2014-06-01

In this paper we maintain that twenty-first century science is, fundamentally, a relational process in which knowledge is produced (or co-produced) through transactions among researchers or among researchers and public stakeholders. We offer an expanded perspective on the practice of twenty-first century science, the production of scientific knowledge, and what community psychology can contribute to these developments. We argue that: (1) trends in science show that research is increasingly being conducted in teams; (2) scientific teams, such as transdisciplinary teams of researchers or of researchers collaborating with various public stakeholders, are better able to address complex challenges; (3) transdisciplinary scientific teams are part of the larger, twenty-first century transformation in science; (4) the concept of heterarchy is a heuristic for team science aligned with this transformation; (5) a contemporary philosophy of science known as perspectivism provides an essential foundation to advance twenty-first century science; and (6) community psychology, through its core principles and practice competencies, offers theoretical and practical expertise for advancing team science and the transformation in science currently underway. We discuss the implications of these points and illustrate them briefly with two examples of transdisciplinary team science from our own work. We conclude that a new narrative is emerging for science in the twenty-first century that draws on interpersonal transactions in teams, and active engagement by researchers with the public to address critical accountabilities. Because of its core organizing principles and unique blend of expertise on the intersection of research and practice, community psychologists are well-prepared to help advance these developments, and thus have much to offer twenty-first century science.

The 11th International Conference on Magnetic Fluids (ICMF 11) was held on July 23-27, 2007 in Kosice, Slovakia. The attendance was high and motivated, in line with previous ten conferences within the ICMF series organized in Udine, Orlando, Bangor, Sendai-Tokyo, Riga, Paris, Bhavnagar, Timisoara, Bremen and Guaruja. The conference in Slovakia reflected the enthusiasm of the scientific community from all around the world, with 256 participants from 30 countries. The main objective of ICMF 11 was to promote the progress and the knowledge in the field of magnetic fluids regarding their chemistry, physical and magnetic properties, heat and mass transfer, surface phenomena, as well as their technological and biomedical applications. As the research on magnetic fluids is essentially interdisciplinary, experts from related areas were invited to present their contributions with a view to extend the frontiers of knowledge in the field and to present the new trends. Submitted communications were refereed by the members of the Scientific Organizing Committee and abstracts were assembled in the Book of Abstracts. Participants presented 180 posters in 2 poster sessions and 56 oral presentations. All presentations helped to expand the frontiers of the area and to establish new bridges between physics, chemistry, technology, biology and medical sciences. Outcomes of this conference are presented by 115 scientific papers, which are published partly in the Journal of Physics: Condensed Matter (JoPCM) and partly in Magnetohydrodynamics (MHD). The organization of the conference was made possible by generous support from the Institute of Experimental Physics and Institute of Geotechnics of Slovak Academy of Sciences, the University of P.J. Safarik and Slovak Physical Society. Financial support from the Ferrotec, Cryosoft, Mikrochem, Liquids research, Askony, U.S. Steel Kosice, is also gratefully acknowledged.

The First International Congress on Ayurveda was held in Milan, Italy in March 2009 and it has been the first scientific event of this kind in western world. This groundbreaking international congress was devoted to human being as the product of interactions between Awareness, Environment and Health, subjects that the West tends to consider separate and independent, but that are believed deeply connected in Ayurveda, whose interdependence defines “The Meaning of Life”. The Congress established a bridge between indian and western philosophy, scientific and biomedical thinking in order to expand knowledge and healthcare. Main attention and address of the invited speakers was on the concept of “relationships” that, connecting living beings with environment, shape Nature itself. This concept is central in Ayurveda but is also common to other western scientific disciplines such as quantum physics and epigenetics that, in the four Sessions of the Congress, were represented by eminent experts. The importance of this event was underlined by the attendance of more than 400 participants and by noteworthy institutional endorsements, that added a significative political dimension of high social impact due to the topical period for CAM acceptance and integration in Europe.

Writing for publication: institutional support provides an enabling environment.

Kramer, Beverley; Libhaber, Elena

2016-04-18

Due to the excessive service delivery loads in public hospitals supported by academic institutions in developing environments, researchers at these institutions have little time to develop scientific writing skills or to write up their research. It is imperative to expand the writing skills of researchers and train the next generation of health sciences academics in order to disseminate research findings. This study reports on the implementation of approaches for writing and publication and the extent of support to staff suffering from the overload of service delivery and of heavy teaching duties. Workshops in scientific writing and writing retreats were initiated and were offered to all staff. Feedback from participants of the writing skills workshops indicated that the workshops provided an injection of confidence and proficiency. Protected writing time resulted in 132 papers submitted to journals and 95 in preparation from 230 participants of the writing retreats over a two year period. Staff commended the off-site, collegial environment, which also supported future collaboration with new-found colleagues. This enabling environment facilitates not only the development of writing skills per se, but also the dissemination of the generated scientific knowledge. In addition, the training in writing skills of this generation will be of value in the training of future cohorts in countries with similar health care deliverables.

Publication ethics and the ghost management of medical publication.

PubMed

Sismondo, Sergio; Doucet, Mathieu

2010-07-01

It is by now no secret that some scientific articles are ghost authored - that is, written by someone other than the person whose name appears at the top of the article. Ghost authorship, however, is only one sort of ghosting. In this article, we present evidence that pharmaceutical companies engage in the ghost management of the scientific literature, by controlling or shaping several crucial steps in the research, writing, and publication of scientific articles. Ghost management allows the pharmaceutical industry to shape the literature in ways that serve its interests. This article aims to reinforce and expand publication ethics as an important area of concern for bioethics. Since ghost-managed research is primarily undertaken in the interests of marketing, large quantities of medical research violate not just publication norms but also research ethics. Much of this research involves human subjects, and yet is performed not primarily to increase knowledge for broad human benefit, but to disseminate results in the service of profits. Those who sponsor, manage, conduct, and publish such research therefore behave unethically, since they put patients at risk without justification. This leads us to a strong conclusion: if medical journals want to ensure that the research they publish is ethically sound, they should not publish articles that are commercially sponsored.

Dizeez: An Online Game for Human Gene-Disease Annotation

Loguercio, Salvatore; Good, Benjamin M.; Su, Andrew I.

2013-01-01

Structured gene annotations are a foundation upon which many bioinformatics and statistical analyses are built. However the structured annotations available in public databases are a sparse representation of biological knowledge as a whole. The rate of biomedical data generation is such that centralized biocuration efforts struggle to keep up. New models for gene annotation need to be explored that expand the pace at which we are able to structure biomedical knowledge. Recently, online games have emerged as an effective way to recruit, engage and organize large numbers of volunteers to help address difficult biological challenges. For example, games have been successfully developed for protein folding (Foldit), multiple sequence alignment (Phylo) and RNA structure design (EteRNA). Here we present Dizeez, a simple online game built with the purpose of structuring knowledge of gene-disease associations. Preliminary results from game play online and at scientific conferences suggest that Dizeez is producing valid gene-disease annotations not yet present in any public database. These early results provide a basic proof of principle that online games can be successfully applied to the challenge of gene annotation. Dizeez is available at http://genegames.org. PMID:23951102

Bridging Research and Environmental Regulatory Processes: The Role of Knowledge Brokers

Federal funding agencies increasingly require research investigators to ensure that federally-sponsored research demonstrates broader societal impact. Specifically, the National Institutes of Environmental Health Sciences (NIEHS) Superfund Research Program (SRP) requires research centers to include research translation and community engagement cores to achieve broader impacts, with special emphasis on improving environmental health policies through better scientific understanding. This paper draws on theoretical insights from the social sciences to show how incorporating knowledge brokers in research centers can facilitate translation of scientific expertise to influence regulatory processes and thus promote public health. Knowledge brokers connect academic researchers with decision-makers, to facilitate the translation of research findings into policies and programs. In this article, we describe the stages of the regulatory process and highlight the role of the knowledge broker and scientific expert at each stage. We illustrate the cooperation of knowledge brokers, scientific experts and policymakers using a case from the Brown University (Brown) SRP. We show how the Brown SRP incorporated knowledge brokers to engage scientific experts with regulatory officials around the emerging public health problem of vapor intrusion. In the Brown SRP, the knowledge broker brought regulatory officials into the research process, to help scientific experts understand the critical nature of this emerging public health threat, and helped scientific experts develop a research agenda that would inform the development of timely measures to protect public health. Our experience shows that knowledge brokers can enhance the impact of environmental research on public health by connecting policy decision-makers with scientific experts at critical points throughout the regulatory process.

Overview This paper presentation shares findings from a granted funded project that sought to expand teacher content knowledge and pedagogy within the fields of marine science and coastal resource management through the implementation of classroom citizen science projects. A secondary goal was to increase middle and high school student interest and participation in marine science and natural resources research. Background A local science & engineering fair has seen a rapid decline in secondary student participants in the past four years. Research has demonstrated that when students are a part of a system of knowledge production (citizen science) they become much more aware, involved and conscious of scientific concepts compared to traditional school laboratory and nature of science activities. This project's primary objectives were to: (a) enhance teacher content expertise in marine science, (b) enrich teacher professional learning, (c) support citizen science classroom projects and inspire student activism and marine science engagement. Methods Project goals were addressed through classroom and meaningful outdoor educational experiences that put content knowledge into field based practices. Teachers learned to apply thier expanded content knowlege through classroom citizen science projects that focus on marine resource conservation issues such as fisheries management, water quality, turtle nesting and biodiversity of coastal ecosystems. These projects would eventually become potential topics of citizen science research topics for their students to pursue. Upon completion of their professional development, participants were urged to establish student Marine Science clubs with the goal of mentoring student submissions into the local science fair. Supplemental awards were possible for the students of project participants. Findings Based on project measures participants significantly increased their knowledge and awareness of presented material marine science and coastal resources. 11/14 teacher participants established citizen science clubs that focused on marine related issues. Science fair participation increased by 42% and of those students whose mentor teacher was a project participant 90% stated they would likely pursue a marine science related major in college.

The number of humanized mouse models for the human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) and other infectious diseases has expanded rapidly over the past 8 years. Highly immunodeficient mouse strains, such as NOD/SCID/gamma chain(null) (NSG, NOG), support better human hematopoietic cell engraftment. Another improvement is the derivation of highly immunodeficient mice, transgenic with human leukocyte antigens (HLAs) and cytokines that supported development of HLA-restricted human T cells and heightened human myeloid cell engraftment. Humanized mice are also used to study the HIV reservoir using new imaging techniques. Despite these advances, there are still limitations in HIV immune responses and deficits in lymphoid structures in these models in addition to xenogeneic graft-versus-host responses. To understand and disseminate the improvements and limitations of humanized mouse models to the scientific community, the NIH sponsored and convened a meeting on April 15, 2015 to discuss the state of knowledge concerning these questions and best practices for selecting a humanized mouse model for a particular scientific investigation. This report summarizes the findings of the NIH meeting.

Physicians from all medical specialties are required to understand the principles of science and to interpret medical literature. Yet, the levels of theoretical and practical knowledge held by Brazilian otorhinolaryngologists has not been evaluated to date. To assess the background and level of scientific knowledge of Brazilian otorhinolaryngologists. Participants of two national ENT meetings were invited to answer a questionnaire to assess scientific practice and knowledge. This study included 73 medical doctors (52% otorhinolaryngologists and 38% residents) aged between 18 and 65 years. About two-thirds have been involved in some form of scientific activity during undergraduate education and/or reported to have written at least one scientific paper. Physicians who took part in research projects felt better prepared to interpret scientific papers and carry out research projects (p = 0.0103 and p = 0.0240, respectively). Respondents who claimed to have participated in research or to have written papers had higher scores on theoretical scientific concepts (p = 0.0101 and p = 0.0103, respectively). However, the overall rate of right answers on questions regarding scientific knowledge was 46.1%. Therefore, a deficiency was observed in the scientific education of Brazilian otorhinolaryngologists. Such deficiency may be mitigated through participation in research.

2017-12-08

After years of tests and development, NASA’s Balloon Program team is on the cusp of expanding the envelope in high-altitude, heavy-lift ballooning with its super pressure balloon (SPB) technology. NASA’s scientific balloon experts are in Wanaka, New Zealand, prepping for the fourth flight of an 18.8 million-cubic-foot (532,000 cubic-meter) balloon, with the ambitious goal of achieving an ultra-long-duration flight of up to 100 days at mid-latitudes. Launch of the pumpkin-shaped, football stadium-size balloon is scheduled for sometime after April 1, 2016, from Wanaka Airport, pending final checkouts and flight readiness of the balloon and supporting systems. Once launched, the SPB, which is made from 22-acres of polyethylene film – similar to a sandwich bag, but stronger and more durable – will ascend to a nearly constant float altitude of 110,000 feet (33.5 km). The balloon will travel eastward carrying a 2,260-pound (1,025 kg) payload consisting of tracking, communications and scientific instruments. NASA expects the SPB to circumnavigate the globe once every one to three weeks, depending on wind speeds in the stratosphere. Read more: go.nasa.gov/1p56xKR NASA image use policy.

Habermann, Barbara; Broome, Marion; Pryor, Erica R.; Ziner, Kim Wagler

2010-01-01

Background Most reports of scientific misconduct have been focused on principal investigators and other scientists (e.g., biostatisticians) involved in the research enterprise. However, by virtue of their position, research coordinators are often closest to the research field where much of misconduct occurs. Objective To describe research coordinators’ experiences with scientific misconduct in their clinical environment. Design The descriptive design was embedded in a larger, cross-sectional national survey. A total of 266 respondents, predominately registered nurses, who answered yes to having first hand knowledge of scientific misconduct in the past year provided open-ended question responses. Methods Content analysis was conducted by the research team, ensuring agreement of core categories and subcategories of misconduct. Findings Research coordinators most commonly learned about misconduct via first-hand witness of the event, with the principal investigator being the person most commonly identified as the responsible party. Five major categories of misconduct were identified: protocol violations, consent violations, fabrication, falsification, and financial conflict of interest. In 70% of cases, the misconduct was reported. In the majority of instances where misconduct was reported, some action was taken. However, in approximately 14% of cases, no action or investigation ensued; in 6.5% of cases the coordinator was either fired or resigned. Conclusions The study demonstrates the need to expand definitions of scientific misconduct beyond fabrication, falsification, and plagiarism to include other practices. The importance of the ethical climate in the institution in ensuring a safe environment to report and an environment where evidence is reviewed cannot be overlooked. PMID:20010045

Designing for students' science learning using argumentation and classroom debate

NASA Astrophysics Data System (ADS)

Bell, Philip Laverne

1998-12-01

This research investigates how to design and introduce an educational innovation into a classroom setting to support learning. The research yields cognitive design principles for instruction involving scientific argumentation and debate. Specifically, eighth-grade students used a computer learning environment to construct scientific arguments and to participate in a classroom debate. The instruction was designed to help students integrate their science understanding by debating: How far does light go, does light die out over distance or go forever until absorbed? This research explores the tension between focusing students' conceptual change on specific scientific phenomena and their development of integrated understanding. I focus on the importance of connecting students' everyday experiences and intuitions to their science learning. The work reported here characterizes how students see the world through a filter of their own understanding. It explores how individual and social mechanisms in instruction support students as they expand the range of ideas under consideration and distinguish between these ideas using scientific criteria. Instruction supported students as they engaged in argumentation and debate on a set of multimedia evidence items from the World-Wide-Web. An argument editor called SenseMaker was designed and studied with the intent of making individual and group thinking visible during instruction. Over multiple classroom trials, different student cohorts were increasingly supported in scientific argumentation involving systematic coordination of evidence with theoretical ideas about light. Students' knowledge representations were used as mediating "learning artifacts" during classroom debate. Two argumentation conditions were investigated. The Full Scope group prepared to defend either theoretical position in the debate. These students created arguments that included more theoretical conjectures and made more conceptual progress in understanding light. The Personal Scope group prepared to defend their original opinion about the debate. These students produced more acausal descriptions of evidence and theorized less in their arguments. Regardless of students' prior knowledge of light, the Full Scope condition resulted in a more integrated understanding. Results from the research were synthesized in design principles geared towards helping future designers. Sharing and refining cognitive design principles offers a productive focus for developing a design science for education.

More than Anecdotes: Fishers’ Ecological Knowledge Can Fill Gaps for Ecosystem Modeling

PubMed Central

Bevilacqua, Ana Helena V.; Carvalho, Adriana R.; Angelini, Ronaldo; Christensen, Villy

2016-01-01

Background Ecosystem modeling applied to fisheries remains hampered by a lack of local information. Fishers’ knowledge could fill this gap, improving participation in and the management of fisheries. Methodology The same fishing area was modeled using two approaches: based on fishers’ knowledge and based on scientific information. For the former, the data was collected by interviews through the Delphi methodology, and for the latter, the data was gathered from the literature. Agreement between the attributes generated by the fishers’ knowledge model and scientific model is discussed and explored, aiming to improve data availability, the ecosystem model, and fisheries management. Principal Findings The ecosystem attributes produced from the fishers’ knowledge model were consistent with the ecosystem attributes produced by the scientific model, and elaborated using only the scientific data from literature. Conclusions/Significance This study provides evidence that fishers’ knowledge may suitably complement scientific data, and may improve the modeling tools for the research and management of fisheries.

2013-12-01

To assess North Carolina pharmacists' level of support for expanded authority to administer human papillomavirus (HPV) vaccines to identify concerns/benefits about expanded authority and to understand what factors predict support for expanded authority. A 16-item electronic survey was e-mailed to all the pharmacists registered with the North Carolina Board of Pharmacy (n = 9502) between January and February 2011 (1600 pharmacists responded). The survey assessed HPV knowledge, level of support for expanded authority, and comfort level of HPV vaccine administration. Many (64%) pharmacists were supportive of a rule change/legislation that would authorize pharmacists to administer HPV vaccines. Younger pharmacists were more supportive of expansion when compared to older pharmacists (r = -.138, P < .001). Pharmacists with higher knowledge scores were more supportive of expansion (r = .223, P < .001). Reporting a higher level of comfort in administering HPV vaccines at their pharmacy was significantly and positively correlated with higher level of support for expansion (r = .624, P < .001). In the multivariate analysis, HPV knowledge, comfort level in administering vaccine, patient age, and type of pharmacy were all predictive of higher level of support for expanded authority where employed. A large proportion of pharmacists were supportive of an expanded role in providing HPV vaccines. Exploring alternate delivery mechanisms like this one is advantageous.

A whole-process progressive training mode to foster optoelectronic students' innovative practical ability

2017-08-01

This article analyzes the features of fostering optoelectronic students' innovative practical ability based on the knowledge structure of optoelectronic disciplines, which not only reveals the common law of cultivating students' innovative practical ability, but also considers the characteristics of the major: (1) The basic theory is difficult, and the close combination of science and technology is obvious; (2)With the integration of optics, mechanics, electronics and computer, the system technology is comprehensive; (3) It has both leading-edge theory and practical applications, so the benefit of cultivating optoelectronic students is high ; (4) The equipment is precise and the practice is costly. Considering the concept and structural characteristics of innovative and practical ability, and adhering to the idea of running practice through the whole process, we put forward the construction of three-dimensional innovation and practice platform which consists of "Synthetically Teaching Laboratory + Innovation Practice Base + Scientific Research Laboratory + Major Practice Base + Joint Teaching and Training Base", and meanwhile build a whole-process progressive training mode to foster optoelectronic students' innovative practical ability, following the process of "basic experimental skills training - professional experimental skills training - system design - innovative practice - scientific research project training - expanded training - graduation project": (1) To create an in - class practical ability cultivation environment that has distinctive characteristics of the major, with the teaching laboratory as the basic platform; (2) To create an extra-curricular innovation practice activities cultivation environment that is closely linked to the practical application, with the innovation practice base as a platform for improvement; (3) To create an innovation practice training cultivation environment that leads the development of cutting-edge, with the scientific research laboratory as a platform to explore; (4) To create an out-campus expanded training environment of optoelectronic major practice and optoelectronic system teaching and training, with the major practice base as an expansion of the platform; (5) To break students' "pre-job training barriers" between school and work, with graduation design as the comprehensive training and testing link.

2012-07-01

Medical knowledge and the volume of scientific articles published have expanded rapidly over the past 50 years. Evidence-based practice (EBP) has developed to help health practitioners get more benefit from the increasing volume of information to solve complex health problems. A format for sharing information in EBP is the critically appraised topic (CAT). A CAT is a standardized summary of research evidence organized around a clinical question, aimed at providing both a critique of the research and a statement of the clinical relevance of results. In this review, we explain the five steps involved in writing a CAT for a clinical purpose ("Ask," "Search," "Appraise," "Apply," and "Evaluate") and introduce some of the useful electronic resources available to help in creating CATs.

The New Landscape of Ethics and Integrity in Scholarly Publishing

NASA Astrophysics Data System (ADS)

Hanson, B.

2016-12-01

Scholarly peer-reviewed publications serve five major functions: They (i) have served as the primary, useful archive of scientific progress for hundreds of years; (ii) have been one principal way that scientists, and more recently departments and institutions, are evaluated; (iii) trigger and are the source of much communication about science to the public; (iv) have been primary revenue sources for scientific societies and companies; and (v) more recently play a critical and codified role in legal and regulatory decisions and advice to governments. Recent dynamics in science as well as in society, including the growth of online communication and new revenue sources, are influencing and altering particularly the first four core functions greatly. The changes in turn are posing important new challenges to the ethics and integrity of scholarly publishing and thus science in ways that are not widely or fully appreciated. For example, the expansion of electronic publishing has raised a number of new challenges for publishers with respect to their responsibility for curating scientific knowledge and even preserving the basic integrity of a manuscript. Many challenges are realted to new or expanded financial conflicts of interest related to the use of metrics such as the Journal Impact Factor, the expansion of alternate business models such as open access and advertising, and the fact that publishers are increasingly involved in framing communication around papers they are publishing. Solutions pose new responsibilities for scientists, publishers, and scientific societies, especially around transparency in their operations.

WE-F-211-01: The Evolving Landscape of Scientific Publishing.

PubMed

Armato, S; Hendee, W; Marshall, C; Curran, B

2012-06-01

The dissemination of scientific advances has changed little since the first peer-reviewed journal was published in 1665 - that is, until this past decade. The print journal, delivered by mail and stored on office shelves and in library reading rooms around the world, has been transformed by immediate, on-demand access to scientific discovery in electronic form. At the same time, the producers and consumers of that scientific content have greatly increased in number, and the balance between supply and demand has required innovations in the world of scientific publishing. In light of technological advances and societal expectations, the dissemination of scientific knowledge has assumed a new form, one that is dynamic and rapidly changing. The academic medical physicist must understand this evolution to ensure that appropriate decisions are made with regard to journal submission strategies and that relevant information on new findings is obtained in a timely manner. Medical Physics is adapting to these changes in substantive ways. This new scientific publishing landscape has implications for subscription models, targeted access through semantic enrichment, user interactivity with content, customized content delivery, and advertising opportunities. Many organizations, including the AAPM, depend on scientific publishing as a significant source of revenue, but web-based delivery raises the expectation that access should be free and threatens this model. The purpose of this symposium is to explore the factors that have contributed to the current state of scientific publishing, to anticipate future directions in this arena, and to convey how medical physicists may benefit from the expanded opportunities, both as authors and as readers. 1. To appreciate the importance of scientific and clinical practice communication for the advancement of the medical physics field 2. To understand the roles of the Editorial Board and the Journal Business Management Committee in the promotion and advancement of Medical Physics 3. To explore technology-driven content delivery mechanisms and their role in facilitating content access and driving content usage 4. To understand the potential benefits and pitfalls of various economic and editorial models of scientific publications and the recent shifts away from the traditional role of libraries. © 2012 American Association of Physicists in Medicine.

Scientific progress: Knowledge versus understanding.

PubMed

Dellsén, Finnur

2016-04-01

What is scientific progress? On Alexander Bird's epistemic account of scientific progress, an episode in science is progressive precisely when there is more scientific knowledge at the end of the episode than at the beginning. Using Bird's epistemic account as a foil, this paper develops an alternative understanding-based account on which an episode in science is progressive precisely when scientists grasp how to correctly explain or predict more aspects of the world at the end of the episode than at the beginning. This account is shown to be superior to the epistemic account by examining cases in which knowledge and understanding come apart. In these cases, it is argued that scientific progress matches increases in scientific understanding rather than accumulations of knowledge. In addition, considerations having to do with minimalist idealizations, pragmatic virtues, and epistemic value all favor this understanding-based account over its epistemic counterpart.

In the era of evidence-based medicine, one of the most important skills a physician needs is the ability to analyze scientific literature critically. This is necessary to keep medical knowledge up to date and to ensure optimal patient care. The aim of this paper is to present an accessible introduction into critical appraisal of scientific articles. Using a selection of international literature, the reader is introduced to the principles of critical reading of scientific articles in medicine. For the sake of conciseness, detailed description of statistical methods is omitted. Widely accepted principles for critically appraising scientific articles are outlined. Basic knowledge of study design, structuring of an article, the role of different sections, of statistical presentations as well as sources of error and limitation are presented. The reader does not require extensive methodological knowledge. As far as necessary for critical appraisal of scientific articles, differences in research areas like epidemiology, clinical, and basic research are outlined. Further useful references are presented. Basic methodological knowledge is required to select and interpret scientific articles correctly.

This panel presentation will exhibit artwork developed in CAVEs and discuss how art methodologies enhance the science of VR through collaboration, interaction and aesthetics. Artists and scientists work alongside one another to expand scientific research and artistic expression and are motivated by exhibiting collaborative virtual environments. Looking towards the arts, such as painting and sculpture, computer graphics captures a visual tradition. Virtual reality expands this tradition to not only what we face, but to what surrounds us and even what responds to our body and its gestures. Art making that once was isolated to the static frame and an optimal point of view is now out and about, in fully immersive mode within CAVEs. Art knowledge is a guide to how the aesthetics of 2D and 3D worlds affect, transform, and influence the social, intellectual and physical condition of the human body through attention to psychology, spiritual thinking, education, and cognition. The psychological interacts with the physical in the virtual in such a way that each facilitates, enhances and extends the other, culminating in a "go together" world. Attention to sharing art experience across high-speed networks introduces a dimension of liveliness and aliveness when we "become virtual" in real time with others.

Gene regulation knowledge commons: community action takes care of DNA binding transcription factors

A large gap remains between the amount of knowledge in scientific literature and the fraction that gets curated into standardized databases, despite many curation initiatives. Yet the availability of comprehensive knowledge in databases is crucial for exploiting existing background knowledge, both for designing follow-up experiments and for interpreting new experimental data. Structured resources also underpin the computational integration and modeling of regulatory pathways, which further aids our understanding of regulatory dynamics. We argue how cooperation between the scientific community and professional curators can increase the capacity of capturing precise knowledge from literature. We demonstrate this with a project in which we mobilize biological domain experts who curate large amounts of DNA binding transcription factors, and show that they, although new to the field of curation, can make valuable contributions by harvesting reported knowledge from scientific papers. Such community curation can enhance the scientific epistemic process. Database URL: http://www.tfcheckpoint.org PMID:27270715

Several developing countries seek to build knowledge-based economies by attempting to expand scientific research capabilities. Characterizing the state and direction of progress in this arena is challenging but important. Here, we employ three metrics: a classical metric of productivity (publications per person), an adapted metric which we denote as Revealed Scientific Advantage (developed from work used to compare publications in scientific fields among countries) to characterize disciplinary specialty, and a new metric, scientific indigeneity (defined as the ratio of publications with domestic corresponding authors) to characterize the locus of scientific activity that also serves as a partial proxy for local absorptive capacity. These metrics-using population and publications data that are available for most countries-allow the characterization of some key features of national scientific enterprise. The trends in productivity and indigeneity when compared across other countries and regions can serve as indicators of strength or fragility in the national research ecosystems, and the trends in specialty can allow regional policy makers to assess the extent to which the areas of focus of research align (or not align) with regional priorities. We apply the metrics to study the Middle East and North Africa (MENA)-a region where science and technology capacity will play a key role in national economic diversification. We analyze 9.8 million publication records between 1981-2013 in 17 countries of MENA from Morocco to Iraq and compare it to selected countries throughout the world. The results show that international collaborators increasingly drove the scientific activity in MENA. The median indigeneity reached 52% in 2013 (indicating that almost half of the corresponding authors were located in foreign countries). Additionally, the regional disciplinary focus in chemical and petroleum engineering is waning with modest growth in the life sciences. We find repeated patterns of stagnation and contraction of scientific activity for several MENA countries contributing to a widening productivity gap on an international comparative yardstick. The results prompt questions about the strength of the developing scientific enterprise and highlight the need for consistent long-term policy for effectively addressing regional challenges with domestic research.

‘Building Core Knowledge - Reconstructing Earth History’: Transforming Undergraduate Instruction by Bringing Ocean Drilling Science on Earth History and Global Climate Change into the Classroom (Invited)

This NSF-funded, Phase 1 CCLI project effectively integrates scientific ocean drilling data and research (DSDP-ODP-IODP-ANDRILL) with education. We have developed, and are currently testing, a suite of data-rich inquiry-based classroom learning materials based on sediment core archives. These materials are suitable for use in introductory geoscience courses that serve general education students, early geoscience majors, and pre-service teachers. 'Science made accessible' is the essence of this goal. Our team consists of research and education specialists from institutions ranging from R1 research to public liberal arts to community college. We address relevant and timely ‘Big Ideas’ with foundational geoscience concepts and climate change case studies, as well transferable skills valued in professional settings. The exercises are divided into separate but inter-related modules including: introduction to cores, seafloor sediments, microfossils and biostratigraphy, paleomagnetism and magnetostratigraphy, climate rhythms, oxygen-isotope changes in the Cenozoic, past Arctic and Antarctic climates, drill site selection, interpreting Arctic and Antarctic sediment cores, onset of Northern Hemisphere glaciation, onset of Antarctic glaciation, and the Paleocene-Eocene Thermal Maximum. Each module has several parts, and each is designed to be used in the classroom, laboratory, or assigned as homework. All exercises utilize authentic data. Students work with scientific uncertainty, practice quantitative and problem-solving skills, and expand their basic geologic and geographic knowledge. Students have the opportunity to work individually and in groups, evaluate real-world problems, and formulate hypotheses. Initial exercises in each module are useful to introduce a topic, gauge prior knowledge, and flag possible areas of student misconception. Comprehensive instructor guides provide essential background information, detailed answer keys, and alternative implementation strategies, as well as providing links to other supplementary materials and examples for assessment. Preliminary assessment data indicates positive gains in student attitudes towards science, and in their content knowledge and scientific skills. In addition, student outcomes appear to depend somewhat on students’ motivation for taking the course and their institution, but are generally independent of students’ class rank or GPA. Our classroom-tested learning materials are being disseminated through a variety of outlets including instructor workshops and eventually to the web.

Three essays on the economics of science policy: The impact of funding, collaboration and research chairs

NASA Astrophysics Data System (ADS)

Mirnezami, Seyed Reza

This thesis studies the determinants that influence the number of citations, the effect of having a research collaboration with top-funded scientists on scientific productivity, and the effect of holding a research chair on scientific productivity. Based on a review study by Bornmann and Daniel (2008), one can argue that non-scientific factors determining the decision to cite do not significantly alter the role of citation as a measure of research impact. Assuming that the number of citations is a good measure for research impact and, in turn, for a certain kind of quality, we showed that the number of articles and the visibility of a researcher, the impact factor of the journal, the size of the research team, and the institutional setting of the university are the important determinants of citation counts. However, we have found that there is no significant effect of public funding and gender in most of the domains examined. The point that funding amount is not a significant determinant of citation counts does not necessarily contradict the positive effect of funding on scientific productivity. We also developed a theoretical model and proposed some hypotheses about the effect of collaboration with top-funded scientists on scientific productivity. We then validated the hypotheses with empirical analysis and showed that such collaboration has a positive effect on scientific productivity. This significant effect may exist through different channels: transfer of tacit knowledge, more scientific publications, economy of scale in knowledge production because of better research equipment, and expanded research network. The results also verified the positive effect of funding, the positive effect of networking (measured by number of co-authors), the inverted U-shaped effect of age, and the fewer number of publications by women compared to men. Finally, we made a distinction between different attributes of research chairs and their effect on scientific productivity. One of the important questions is to find out whether a research chair still has better scientific productivity (compared to non-chair holders) after controlling for the research funds available to the researchers. To investigate that question, we employed a matching technique to identify pairs of scientists (chair and non-chair holders) of the same gender, funding and research field. After such matching, we found that the effect of the Canada research chair program on scientific productivity remains significant and positive, while the effect of industrial chairs and the chairs appointed by the Canadian federal granting councils (NSERC and CIHR) become non-significant. This finding highlights the effectiveness of our matching technique methodology; because before matching, holding any type of chair had a positive and significant effect on scientific productivity. This finding highlights the special attributes of the Canada research chair program, which are not replicated in other chairs. Those specific attributes may significantly push scientific productivity. For example, Canada research chairs are generally associated with some degree of prestige or higher visibility to recruit talented students or to have research collaboration with top scientists in the field. In addition, the Canada research chair program has a firm and efficient method of allocation (which is explained in the thesis). This approach institutionally synchronizes different chairs in universities and research fields. The fact that other types of research chairs, once matched with equivalent scientists, do not have an impact on scientific output in terms of quantity does not imply that these chair holders are lesser scientists, but that they are devoting part of their time to other endeavours of a more practical nature. Hence universities are maintaining a balance between the pursuit of pure scientific knowledge and its application to socioeconomic benefits. By solely studying scientific articles, we are missing a great deal of the university professors' activities. Although not trivial, future research should aim to cast a wider net on outputs, outcomes and impacts of university research.

The Fragile X Mental Retardation Syndrome 20 Years After the FMR1 Gene Discovery: an Expanding Universe of Knowledge

Rousseau, François; Labelle, Yves; Bussières, Johanne; Lindsay, Carmen

2011-01-01

The fragile X mental retardation (FXMR) syndrome is one of the most frequent causes of mental retardation. Affected individuals display a wide range of additional characteristic features including behavioural and physical phenotypes, and the extent to which individuals are affected is highly variable. For these reasons, elucidation of the pathophysiology of this disease has been an important challenge to the scientific community. 1991 marks the year of the discovery of both the FMR1 gene mutations involved in this disease, and of their dynamic nature. Although a mouse model for the disease has been available for 16 years and extensive research has been performed on the FMR1 protein (FMRP), we still understand little about how the disease develops, and no treatment has yet been shown to be effective. In this review, we summarise current knowledge on FXMR with an emphasis on the technical challenges of molecular diagnostics, on its prevalence and dynamics among populations, and on the potential of screening for FMR1 mutations.

Nanotechnology is an evolving scientific field that has allowed the manufacturing of materials with novel physicochemical and biological properties, offering a wide spectrum of potential applications. Properties of nanoparticles that contribute to their usefulness include their markedly increased surface area in relation to mass, surface reactivity and insolubility, ability to agglomerate or change size in different media and enhanced endurance over conventional-scale substance. Here, we review nanoparticle classification and their emerging applications in several fields; from active food packaging to drug delivery and cancer research. Nanotechnology has exciting therapeutic applications, including novel drug delivery for the treatment of cancer. Additionally, we discuss that exposure to nanostructures incorporated to polymer composites, may result in potential human health risks. Therefore, the knowledge of processes, including absorption, distribution, metabolism and excretion, as well as careful toxicological assessment is critical in order to determine the effects of nanomaterials in humans and other biological systems. Expanding the knowledge of nanoparticle toxicity will facilitate designing of safer nanocomposites and their application in a beneficial manner. Copyright © 2016 Elsevier Ltd. All rights reserved.

In a period of compilation, original observations and expansion (900-1100 A.D.), Persians described new clinical manifestations of the diseases and expanded the earlier knowledge of materia medica. In the epoch of the Arabic language domination in the scientific literature of this period, advent of medical authors to write in Farsi shined in the Persian principalities. Akhawayani Bokhari was by far the most outstanding scholar of the time who wrote one of the earliest pandects of medicine of the period, the Hidayat al-Mutallimin fi al-Tibb (Learner's Guide to Medicine) in new Persian. The Hidayat is a relatively short and simplified digest of medicine at the time providing a glimpse of high level of medical education at the Samanid period (819-999). The present article is a translation of the sections of the Hidayat related to the pulse and its characters and conditions affecting the pulse in an attempt to increase our knowledge of the medicine, and particularly the pulse examination throughout the medieval era.

Scientific knowledge and modern prospecting

USGS Publications Warehouse

Neuerburg, G.J.

1985-01-01

Modern prospecting is the systematic search for specified and generally ill-exposed components of the Earth's crust known as ore. This prospecting depends entirely on reliable, or scientific knowledge for guidance and for recognition of the search objects. Improvement in prospecting results from additions and refinements to scientific knowledge. Scientific knowledge is an ordered distillation of observations too numerous and too complex in themselves for easy understanding and for effective management. The ordering of these observations is accomplished by an evolutionary hierarchy of abstractions. These abstractions employ simplified descriptions consisting of characterization by selected properties, sampling to represent much larger parts of a phenomenon, generalized mappings of patterns of geometrical and numerical relations among properties, and explanation (theory) of these patterns as functional relations among the selected properties. Each abstraction is predicated on the mode of abstraction anticipated for the next higher level, so that research is a deductive process in which the highest level, theory, is indispensible for the growth and refinement of scientific knowledge, and therefore of prospecting methodology. ?? 1985 Springer-Verlag.

Promoting elementary students' epistemology of science through computer-supported knowledge-building discourse and epistemic reflection

NASA Astrophysics Data System (ADS)

Lin, Feng; Chan, Carol K. K.

2018-04-01

This study examined the role of computer-supported knowledge-building discourse and epistemic reflection in promoting elementary-school students' scientific epistemology and science learning. The participants were 39 Grade 5 students who were collectively pursuing ideas and inquiry for knowledge advance using Knowledge Forum (KF) while studying a unit on electricity; they also reflected on the epistemic nature of their discourse. A comparison class of 22 students, taught by the same teacher, studied the same unit using the school's established scientific investigation method. We hypothesised that engaging students in idea-driven and theory-building discourse, as well as scaffolding them to reflect on the epistemic nature of their discourse, would help them understand their own scientific collaborative discourse as a theory-building process, and therefore understand scientific inquiry as an idea-driven and theory-building process. As hypothesised, we found that students engaged in knowledge-building discourse and reflection outperformed comparison students in scientific epistemology and science learning, and that students' understanding of collaborative discourse predicted their post-test scientific epistemology and science learning. To further understand the epistemic change process among knowledge-building students, we analysed their KF discourse to understand whether and how their epistemic practice had changed after epistemic reflection. The implications on ways of promoting epistemic change are discussed.

Teaching for conceptual change: An intervention to promote deeper understanding of diffusion and osmosis

NASA Astrophysics Data System (ADS)

Berg, Cheryl

Emergent processes are distinguished from non-emergent processes on the basis of the qualitative relationships among the agents' interactions and the causal relationships between the agents' interactions and the pattern. Research suggests students often have robust misconceptions about emergent processes (such as diffusion) because they do not have the mental model to interpret these processes This study investigates the extent to which a domain-general understanding of emergent processes can help provide students with an enhanced understanding of diffusion and osmosis This is a quasi-experimental study using non-equivalent groups design to compare the treatment and control groups. Sixty-six community college students enrolled in an introductory biology course comprised the participants. Students' prior knowledge about emergent processes, diffusion, and osmosis were assessed by pre-tests. The treatment group received the intervention -- an instructional module about the differences between scientific processes that are emergent versus processes that are non-emergent. The control group did not receive the intervention but received the process assessment to determine incoming knowledge about scientific processes and any gains in knowledge about scientific processes. Both groups received the same specific content instruction about diffusion and osmosis, which was derived from the regular and established curriculum for the course. Both groups were given post-tests to assess whether they learned the concepts, and whether they were able to achieve a deep understanding that resulted in a comprehension of the transport of substances across cell membranes and how that might be applied in particular health-related situations. Data were analyzed using t-tests and analysis of variance. No statistically significant differences were found between the two groups based on the learning measures Limitations include sample restrictions and not taking into account individual ability levels of the participants. In addition, the short length of this intervention may not provide adequate time for students to successfully acquire the schema to understand conceptually difficult science concepts such as diffusion and osmosis. Future directions of research include expanding the sample size and length of exposure to the intervention, in addition to examining the individual ability levels of the participants.

Endangered Mangroves in Segara Anakan, Indonesia: Effective and Failed Problem-Solving Policy Advice.

PubMed

Dharmawan, Budi; Böcher, Michael; Krott, Max

2017-09-01

The success of scientific knowledge transfer depends on if the decision maker can transform the scientific advice into a policy that can be accepted by all involved actors. We use a science-policy interactions model called research-integration-utilization to observe the process of scientific knowledge transfer in the case of endangered mangroves in Segara Anakan, Indonesia. Scientific knowledge is produced within the scientific system (research), science-based solutions to problems are practically utilized by political actors (utilization), and important links between research and utilization must be made (integration). We looked for empirical evidence to test hypotheses about the research-integration-utilization model based on document analysis and expert interviews. Our study finds that the failures in knowledge transfer are caused by the inappropriate use of scientific findings. The district government is expected by presidential decree to only used scientifically sound recommendations as a prerequisite for designing the regulation. However, the district government prefers to implement their own solutions because they believe that they understand the solutions better than the researcher. In the process of integration, the researcher cannot be involved, since the selection of scientific recommendations here fully depends on the interests of the district government as the powerful ally.

2015-10-01

A study is presented that explores how students' knowledge structures, as related to the scientific method, compare at different student ages. A word association test comprised of ten total stimulus words, among them experiment, science fair, and hypothesis, is used to probe the students' knowledge structures. Students from grades four, five, and eight, as well as first-year college students were tested to reveal their knowledge structures relating to the scientific method. Younger students were found to have a naïve view of the science process with little understanding of how science relates to the real world. However, students' conceptions about the scientific process appear to be malleable, with science fairs a potentially strong influencer. The strength of associations between words is observed to change from grade to grade, with younger students placing science fair near the center of their knowledge structure regarding the scientific method, whereas older students conceptualize the scientific method around experiment.

"The NASA Solar System Exploration n Research Vistula Institute: Year 1 with New Teams with New and Old Partners!"

2015-08-01

Recognizing that science enables exploration, and exploration enables science, NASA created the Solar System Exploration Research Virtual Institute (SSERVI) to address basic and applied scientific questions fundamental to understanding the Moon, Near Earth Asteroids, and the moons of Mars. Primarily using virtual tools to communicate has eliminated the need for a traditional bricks and mortar institute, allowing the hundreds of researchers across the U.S. and the eight international partners to easily communicate and collaborate, from wherever they are. The small, central office located at NASA Ames Research Center in the heart of Silicon Valley, coordinates the institute activities. Newly found synergies across the teams, the sharing of data and facilities, and the ease of communication increase the efficiencies of scientific discovery. More importantly, the birth of ideas formed at the intersection of disparate disciplines can readily be pursued by groups that might not otherwise have formed, or even met! SSERVI follows on the heels of the highly successful NASA Lunar Science Institute (NLSI), a virtual institute dedicated solely to studies of the Moon. The creation of SSERVI has not only expanded our knowledge of the Earth’s nearest neighbor to include other stepping-stones to Mars, but also furthered our ability to address the scientific and technological questions we need to know…before we go!

Tropical Medicine and Animal Diseases: Onderstepoort and the Development of Veterinary Science in South Africa 1908-1950.

PubMed

Brown, Karen

2005-09-01

This article traces the development of agricultural science at the Onderstepoort Veterinary Institute, near Pretoria, from its founding in 1908 until the 1950s, by which time many enzootic and epizootic diseases had either been eradicated, or were largely controllable through various forms of prophylaxis. The Institute demonstrated the political and economic significance attributed to the pastoral industry in South Africa and the conviction that scientific discoveries could increase output. During this period, researchers explicated the aetiology and provenance of hitherto mysterious diseases such as lamsiekte, geeldikkop and African horsesickness. They developed vaccines, some of which were adopted internationally. The nature of their investigations showed that veterinary science increasingly entailed more than just progress in biomedical procedures. Ecological factors, in particular the nutritional state of the veld, became a priority from the 1920s onwards as veterinarians saw their function as promoting animal health as well as eliminating disease. Dealing with contagious infections also incorporated less welcome, and at times controversial, approaches to disease control. The imposition of pastoral regulations illustrated the expanding powers of the South African state, founded on presumptions of scientific legitimacy. The article also explores the contribution made by African communities and settler farmers to the institutionalisation of veterinary knowledge, as well as the role South African researchers played in the evolution of a colonial, as well as an increasingly international, scientific culture.

Linking knowledge with action in the pursuit of sustainable water-resources management

Managing water for sustainable use and economic development is both a technical and a governance challenge in which knowledge production and sharing play a central role. This article evaluates and compares the role of participatory governance and scientific information in decision-making in four basins in Brazil, Mexico, Thailand, and the United States. Water management institutions in each of the basins have evolved during the last 10–20 years from a relatively centralized water-management structure at the state or national level to a decision structure that involves engaging water users within the basins and the development of participatory processes. This change is consistent with global trends in which states increasingly are expected to gain public acceptance for larger water projects and policy changes. In each case, expanded citizen engagement in identifying options and in decision-making processes has resulted in more complexity but also has expanded the culture of integrated learning. International funding for water infrastructure has been linked to requirements for participatory management processes, but, ironically, this study finds that participatory processes appear to work better in the context of decisions that are short-term and easily adjusted, such as water-allocation decisions, and do not work so well for longer-term, high-stakes decisions regarding infrastructure. A second important observation is that the costs of capacity building to allow meaningful stakeholder engagement in water-management decision processes are not widely recognized. Failure to appreciate the associated costs and complexities may contribute to the lack of successful engagement of citizens in decisions regarding infrastructure. PMID:20080611

WILDLIFE HEALTH 2.0: BRIDGING THE KNOWLEDGE-TO-ACTION GAP.

PubMed

Stephen, Craig

2017-01-01

The unprecedented threats to the health and sustainability of wildlife populations are inspiring conversations on the need to change the way knowledge is generated, valued, and used to promote action to protect wildlife health. Wildlife Health 2.0 symbolizes the need to investigate how to improve connections between research expertise and policy or practices to protect wildlife health. Two imperatives drive this evolution: 1) growing frustrations that research is inadequately being used to inform management decisions and 2) the realization that scientific certainty is context specific for complex socioecologic issues, such as wildlife health. Failure to appreciate the unpredictability of complex systems or to incorporate ethical and cultural dimensions of decisions has limited the contribution of research to decision making. Wildlife health can draw from scholarship in other fields, such as public health and conservation, to bridge the knowledge-to-action gap. Efforts to integrate science into decisions are more likely to be effective when they enhance relevance, credibility, and legitimacy of information for people who will make or be affected by management decisions. A Wildlife Health 2.0 agenda is not a rejection of the current research paradigm but rather a call to expand our areas of inquiry to ensure that the additional contextual understanding is generated to help decision makers make good choices.

As the Enlightenment drew to a close, translation had gradually acquired an increasingly important role in the international circulation and transmission of scientific knowledge. Yet comparatively little attention has been paid to the translators responsible for making such accounts accessible in other languages, some of whom were women. In this article I explore how European women cast themselves as intellectually enquiring, knowledgeable and authoritative figures in their translations. Focusing specifically on the genre of scientific travel writing, I investigate the narrative strategies deployed by women translators to mark their involvement in the process of scientific knowledge-making. These strategies ranged from rhetorical near-invisibility, driven by women's modest marginalization of their own public engagement in science, to the active advertisement of themselves as intellectually curious consumers of scientific knowledge. A detailed study of Elizabeth Helme's translation of the French ornithologist François le Vaillant's Voyage dans l'intérieur de l'Afrique [Voyage into the Interior of Africa] (1790) allows me to explore how her reworking of the original text for an Anglophone reading public enabled her to engage cautiously - or sometimes more openly - with questions regarding how scientific knowledge was constructed, for whom and with which aims in mind.

A crisis in the marketplace: how food marketing contributes to childhood obesity and what can be done.

PubMed

Harris, Jennifer L; Pomeranz, Jennifer L; Lobstein, Tim; Brownell, Kelly D

2009-01-01

Reducing food marketing to children has been proposed as one means for addressing the global crisis of childhood obesity, but significant social, legal, financial, and public perception barriers stand in the way. The scientific literature documents that food marketing to children is (a) massive; (b) expanding in number of venues (product placements, video games, the Internet, cell phones, etc.); (c) composed almost entirely of messages for nutrient-poor, calorie-dense foods; (d) having harmful effects; and (e) increasingly global and hence difficult to regulate by individual countries. The food industry, governmental bodies, and advocacy groups have proposed a variety of plans for altering the marketing landscape. This article reviews existing knowledge of the impact of marketing and addresses the value of various legal, legislative, regulatory, and industry-based approaches to change.

On the Limitations of Biological Knowledge

PubMed Central

Dougherty, Edward R; Shmulevich, Ilya

2012-01-01

Scientific knowledge is grounded in a particular epistemology and, owing to the requirements of that epistemology, possesses limitations. Some limitations are intrinsic, in the sense that they depend inherently on the nature of scientific knowledge; others are contingent, depending on the present state of knowledge, including technology. Understanding limitations facilitates scientific research because one can then recognize when one is confronted by a limitation, as opposed to simply being unable to solve a problem within the existing bounds of possibility. In the hope that the role of limiting factors can be brought more clearly into focus and discussed, we consider several sources of limitation as they apply to biological knowledge: mathematical complexity, experimental constraints, validation, knowledge discovery, and human intellectual capacity.

Reflections on curiosity.

PubMed

van Bemmel, J H

2008-01-01

The purpose of this article is to show that curiosity is the driving force behind all scientific endeavors. The second purpose is to show that all science is constrained on its underlying assumptions. Three examples are used to illustrate the above theses: one from cosmology, the second from biomedical research, and the third from the formalization of human reasoning in a computer. The three examples are supported by quotes from Albert Einstein. Research in cosmology shows that the horizon of our knowledge is continuously expanding but that major scientific questions remain to be solved. The second example from biomedicine explains that the more we discover of the details of living phenomena, the more complex they appear to be. The example involving human reasoning makes clear that the brain is still largely unknown territory. Like Einstein, who said he held 'humble admiration of the illimitable superior spirit who reveals himself in the slight details we are able to perceive with our frail and feeble mind', I have a deep admiration for the Architect who reveals himself in the details that we are privileged to study in our research. As Albert Einstein said: The important thing is not to stop questioning. Curiosity has its own reason for existing.

Earth-Directed X-Class Flare and CME

NASA Image and Video Library

2014-09-15

An active region just about squarely facing Earth erupted with an X 1.6 flare (largest class) as well as a coronal mass ejection (CME) on Sept. 10-11, 2014. This event featured both a long flare decay time and a storm of electrically charged, energetic particles. The particles can be seen as bright white specks scattering across the frames. The coronagraph movie shows the cloud of particles expanding in all directions as if it were creating a halo around the Sun. Data shows that the CME was heading towards Earth that could generate strong aurora displays several days later. In coronagraph images the Sun (represented by the small white circle in the center) is blocked by an occulting disk so that we can observe faint features in the corona and beyond.

Abstract The number of humanized mouse models for the human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) and other infectious diseases has expanded rapidly over the past 8 years. Highly immunodeficient mouse strains, such as NOD/SCID/gamma chainnull (NSG, NOG), support better human hematopoietic cell engraftment. Another improvement is the derivation of highly immunodeficient mice, transgenic with human leukocyte antigens (HLAs) and cytokines that supported development of HLA-restricted human T cells and heightened human myeloid cell engraftment. Humanized mice are also used to study the HIV reservoir using new imaging techniques. Despite these advances, there are still limitations in HIV immune responses and deficits in lymphoid structures in these models in addition to xenogeneic graft-versus-host responses. To understand and disseminate the improvements and limitations of humanized mouse models to the scientific community, the NIH sponsored and convened a meeting on April 15, 2015 to discuss the state of knowledge concerning these questions and best practices for selecting a humanized mouse model for a particular scientific investigation. This report summarizes the findings of the NIH meeting. PMID:26670361

The Scientific Challenge of Expanding the Frontiers of Nutrition.

Rezzi, Serge; Solari, Soren; Bouche, Nicolas; Baetge, Emmanuel E

2016-01-01

Nutritional research is entering a paradigm shift which necessitates the modeling of complex interactions between diet, genetics, lifestyle, and environmental factors. This requires the development of analytical and processing capabilities for multiple data and information sources to be able to improve targeted and personalized nutritional approaches for the maintenance of health. Ideally, such knowledge will be employed to underpin the development of concepts that combine consumer and medical nutrition with diagnostic targeting for early intervention designed to maintain proper metabolic homeostasis and delay the onset of chronic diseases. Nutritional status is fundamental to any description of health, and when combined with other data on lifestyle, environment, and genetics, it can be used to drive stratified or even personalized nutritional strategies for health maintenance and preventive medicine. In this work, we will discuss the importance of developing new nutrient assessment methods and diagnostic capabilities for nutritional status to generate scientific hypotheses and actionable concepts from which to develop targeted and eventually personalized nutritional solutions for health protection. We describe efforts to develop algorithms for dietary nutrient intake and a holistic nutritional profiling platform as the basis of understanding the complex nutrition and health interactome. © 2016 Nestec Ltd., Vevey/S.

Human resources for health: global crisis and international cooperation.

PubMed

Portela, Gustavo Zoio; Fehn, Amanda Cavada; Ungerer, Regina Lucia Sarmento; Poz, Mario Roberto Dal

2017-07-01

From the 1990s onwards, national economies became connected and globalized. Changes in the demographic and epidemiological profile of the population highlighted the need for further discussions and strategies on Human Resources for Health (HRH). The health workforce crisis is a worldwide phenomenon. It includes: difficulties in attracting and retaining health professionals to work in rural and remote areas, poor distribution and high turnover of health staff particularly physicians, poor training of health workforces in new sanitation and demographic conditions and the production of scientific evidence to support HRH decision making, policy management, programs and interventions. In this scenario, technical cooperation activities may contribute to the development of the countries involved, strengthening relationships and expanding exchanges as well as contributing to the production, dissemination and use of technical scientific knowledge and evidence and the training of workers and institutional strengthening. This article aims to explore this context highlighting the participation of Brazil in the international cooperation arena on HRH and emphasizing the role of the World Health Organization in confronting this crisis that limits the ability of countries and their health systems to improve the health and lives of their populations.

Cannabis Smoking in 2015

PubMed Central

Biehl, Jason R.

2015-01-01

Recent legislative successes allowing expanded access to recreational and medicinal cannabis have been associated with its increased use by the public, despite continued debates regarding its safety within the medical and scientific communities. Despite legislative changes, cannabis is most commonly used by smoking, although alternatives to inhalation have also emerged. Moreover, the composition of commercially available cannabis has dramatically changed in recent years. Therefore, developing sound scientific information regarding its impact on lung health is imperative, particularly because published data conducted prior to widespread legalization are conflicting and inconclusive. In this commentary, we delineate major observations of epidemiologic investigations examining cannabis use and the potential associated development of airways disease and lung cancer to highlight gaps in pulmonary knowledge. Additionally, we review major histopathologic alterations related to smoked cannabis and define specific areas in animal models and human clinical translational investigations that could benefit from additional development. Given that cannabis has an ongoing classification as a schedule I medication, federal funding to support investigations of modern cannabis use in terms of medicinal efficacy and safety profile on lung health have been elusive. It is clear, however, that the effects of inhaled cannabis on lung health remain uncertain and given increasing use patterns, are worthy of further investigation. PMID:25996274

New Energetic Particle Data and Products from the GOES Program

NASA Astrophysics Data System (ADS)

Onsager, Terrance; Rodriguez, Juan

The NOAA Geostationary Operational Environmental Satellite (GOES) program has provided continuous, real-time measurements of the near-Earth space environment for decades. In addition to their scientific value, the GOES energetic particle measurements are the basis for a variety of space weather products and services, including the forecasting of elevated energetic particle levels, real-time knowledge of the satellite environment at geostationary orbit, and data to allow post-event analyses when satellite anomalies occur. The GOES satellites have traditionally provided measurements of high-energy electrons, protons, and alpha particles (100s of keV to 100s of MeV). Beginning with the launch of GOES-13 in 2006, the measurement capabilities were expanded to include medium-energy electrons and protons (10s to 100s of keV) with pitch angle resolution. The next generation of GOES satellites, starting with GOES-R in 2016, will include low-energy electrons and ions (10s of eV to 10s of keV) as well as energetic heavy ions. In this presentation, we will overview the GOES particle measurements available now and in the future and describe the space weather services and scientific investigations that these data support.

Exposure to science, perspectives on science and religion, and religious commitment in young adulthood.

PubMed

Uecker, Jeremy E; Longest, Kyle C

2017-07-01

Social scientists know very little about the consequences of exposure to scientific knowledge and holding different perspectives on science and religion for individuals' religious lives. Drawing on secularization and post-secular theories, we develop and test several hypotheses about the relationships among exposure to scientific knowledge, perspectives on religion and science, and religious commitment using panel data from the National Study of Youth and Religion. Our findings indicate that religious faith is strongest among young adults who: (1) accommodate scientific knowledge into their religious perspective, or (2) reject scientific knowledge that directly contradicts their religious beliefs about the origins of the world. Young adults are also more likely to have lower religious commitment when they view science and religion as independent institutions, lending support to secularization ideas about how social differentiation secularizes individuals. We further find that mere exposure to scientific knowledge, in terms of majoring in biology or acknowledging conflict between the teachings of religion and science, is usually not sufficient to undermine religious commitment.

Protecting Traditional Knowledge Related to Biological Resources: Is Scientific Research Going to Become More Bureaucratized?

Reddy, Prashant; Lakshmikumaran, Malathi

2015-01-01

For the past several decades, there has been a world debate on the need for protecting traditional knowledge. A global treaty appears to be a distant reality. Of more immediate concern are the steps taken by the global community to protect access to biological resources in the name of protecting traditional knowledge. The Indian experience with implementing the Convention on Biological Diversity has created substantial legal uncertainty in collaborative scientific research between Indians and foreigners apart from bureaucratizing the entire process of scientific research, especially with regard to filing of applications for intellectual property rights. The issue therefore is whether the world needs to better balance the needs of the scientific community with the rights of those who have access to traditional knowledge. PMID:26101205

Knowledge gain and behavioral change in citizen-science programs.

2011-12-01

Citizen-science programs are often touted as useful for advancing conservation literacy, scientific knowledge, and increasing scientific-reasoning skills among the public. Guidelines for collaboration among scientists and the public are lacking and the extent to which these citizen-science initiatives change behavior is relatively unstudied. Over two years, we studied 82 participants in a three-day program that included education about non-native invasive plants and collection of data on the occurrence of those plants. Volunteers were given background knowledge about invasive plant ecology and trained on a specific protocol for collecting invasive plant data. They then collected data and later gathered as a group to analyze data and discuss responsible environmental behavior with respect to invasive plants. We tested whether participants without experience in plant identification and with little knowledge of invasive plants increased their knowledge of invasive species ecology, participation increased knowledge of scientific methods, and participation affected behavior. Knowledge of invasive plants increased on average 24%, but participation was insufficient to increase understanding of how scientific research is conducted. Participants reported increased ability to recognize invasive plants and increased awareness of effects of invasive plants on the environment, but this translated into little change in behavior regarding invasive plants. Potential conflicts between scientific goals, educational goals, and the motivation of participants must be considered during program design. ©2011 Society for Conservation Biology.

Fostering Environmental Literacy For A Changing Earth: Interactive and Participatory Outreach Programs at Biosphere 2

NASA Astrophysics Data System (ADS)

Pavao-Zuckerman, M.; Huxman, T.; Morehouse, B.

2008-12-01

Earth system and ecological sustainability problems are complex outcomes of biological, physical, social, and economic interactions. A common goal of outreach and education programs is to foster a scientifically literate community that possesses the knowledge to contribute to environmental policies and decision making. Uncertainty and variability that is both inherent in Earth system and ecological sciences can confound such goals of improved ecological literacy. Public programs provide an opportunity to engage lay-persons in the scientific method, allowing them to experience science in action and confront these uncertainties face-on. We begin with a definition of scientific literacy that expands its conceptualization of science beyond just a collection of facts and concepts to one that views science as a process to aid understanding of natural phenomena. A process-based scientific literacy allows the public, teachers, and students to assimilate new information, evaluate climate research, and to ultimately make decisions that are informed by science. The Biosphere 2 facility (B2) is uniquely suited for such outreach programs because it allows linking Earth system and ecological science research activities in a large scale controlled environment setting with outreach and education opportunities. A primary outreach goal is to demonstrate science in action to an audience that ranges from K-12 groups to retired citizens. Here we discuss approaches to outreach programs that focus on soil-water-atmosphere-plant interactions and their roles in the impacts and causes of global environmental change. We describe a suite of programs designed to vary the amount of participation a visitor has with the science process (from passive learning to data collection to helping design experiments) to test the hypothesis that active learning fosters increased scientific literacy and the creation of science advocates. We argue that a revised framing of the scientific method with a more open role for citizens in science will have greater success in fostering science literacy and produce a citizenry that is equipped to tackle complex environmental decision making.

Scientific Research & Subsistence: Protocols to Ensure Co-Existence

NASA Astrophysics Data System (ADS)

Nachman, C.; Holman, A.; DeMaster, D.

2017-12-01

Commercial, industrial, and research interests in the Arctic are expanding rapidly. Potentials are numerous and exciting, giving rise to the need for guidelines to ensure interactions among waterway users do not conflict. Of particular concern is the potential for adverse impacts to U.S. Arctic coastal communities that rely on living marine resources for nutritional and cultural health, through subsistence hunts from small craft, ice edges, and shore. Recent events raised concerns over research surveys potentially interfering with subsistence hunts in the Bering, Chukchi, and Beaufort Seas. Incidents led to calls by Native Alaskan communities to restrict science activities with a mixed response from the scientific community (i.e., some sympathetic, some defensive). With a common goal of wanting to mitigate this potential interaction, Federal agencies made a commitment in the National Strategy for the Arctic Region to coordinate and consult with Alaska Natives and also to pursue responsible Arctic stewardship, with understanding through scientific research and traditional knowledge. The effort to create a "Standard of Care" for research surveys incorporates years of experience by subsistence hunters working to mitigate impacts of other anthropogenic activities in the region, as well as best practices by many in the research community. The protocols are designed to ensure potential conflicts between the scientific research community and subsistence hunters are avoided and to encourage mutual assistance and collaboration between researchers and hunters. The guidelines focus on enhancing communication between researchers and subsistence hunters before, during, and after research occurs. The best management practices outlined in the Standard of Care assist those overseeing and funding scientific research in making decisions about how best to accomplish the goals of the research while ensuring protection of the Alaska subsistence lifestyle. These protocols could also be used in a larger context to address concerns over increased vessel traffic from other activities. We will outline the importance of establishing the guidelines, describe the general process, and highlight examples of positive interactions with Alaska Native hunters during scientific research operations using this protocol.

Opposing ends of the spectrum: Exploring trust in scientific and religious authorities.

Given the ethical questions that surround emerging science, this study is interested in studying public trust in scientific and religious authorities for information about the risks and benefits of science. Using data from a nationally representative survey of American adults, we employ regression analysis to better understand the relationships between several variables-including values, knowledge, and media attention-and trust in religious organizations and scientific institutions. We found that Evangelical Christians are generally more trusting of religious authority figures to tell the truth about the risks and benefits of science and technology, and only slightly less likely than non-Evangelicals to trust scientific authorities for the same information. We also found that many Evangelicals use mediated information and science knowledge differently than non-Evangelicals, with both increased knowledge and attention to scientific media having positive impacts on trust in scientific authorities among the latter, but not the former group.

Scientific literacy for decisionmaking and the social construction of scientific knowledge

NASA Astrophysics Data System (ADS)

Bingle, Wade H.; Gaskell, P. James

Citizens are often required to make decisions about socioscientific issues in a climate characterized by conflict within both the scientific community and the larger society. Central to the process of decisionmaking is a critical examination of the relevant scientific knowledge involved. Individuals capable of performing this task can be considered scientifically literate in a decisionmaking sense. In this article we explore two ways of critically examining scientific knowledge in the context of a current socioscientific dispute: NASA's Galileo Mission to Jupiter. The two approaches we outline, termed the positivist and social constructivist positions, are examined in terms of their inherent views concerning the nature of scientific knowledge, in particular their use of constitutive and contextual values when evaluating knowledge claims. Because the social constructivist position acknowledges the importance of contextual values, it provides citizens with accessible standards for evaluating scientific knowledge claims. The positivist position, on the other hand, relies on constitutive values which we show are normally inaccessible to ordinary citizens. The positivist position, however, is most closely associated with the predominant social issues approach to science-technology-society (STS) education. Implications little consensus about which statements are fact (i.e., will remain stable when challenged) and which opinion, (i.e., will be modified when challenged). All knowledge is potentially unreliable when one is dealing with a socioscientific dispute.The adoption of a social constructivist view of scientific knowledge and its inherent way of evaluating knowledge claims clearly has implications for future approaches to STS education. Although one approach might be to offer a course in the history, philosophy, and sociology of science, this would not be useful without reference to the way in which such knowledge can help students to understand the context of a conflict within the society of scientists and the larger society. As Rosenthal (1989) argues, a synthesis is needed in which social issues are seen as a vehicle for studying the social studies of science and the social issues are seen as a way of making sense of social aspects of science. However, this way of teaching STS may be difficult to implement. In British Columbia, for example, science teachers have resisted efforts to include the social context of science within a traditional university-oriented physics course (Gaskell, 1992) and to teach a grade 11 social issues oriented sicence and technology course (Gaskell, 1989). This may be because the current social issues approach is most compatible with traditional science content as it is now taught: it simply shows the relevance of textbook knowledge (ready-made science) to contemporary probles. The shift to the approach suggested above will require a more drastic reorganization of the curriculum, one that may be resisted by the current stakeholders in science education (Duschl, 1988; Gaskell, 1989).

J.G. Crowther's War: Institutional strife at the BBC and British Council.

Jones, Allan

2016-06-01

Science writer, historian and administrator J.G. Crowther (1899-1983) had an uneasy relationship with the BBC during the 1920s and 1930s, and was regarded with suspicion by the British security services because of his left politics. Nevertheless the Second World War saw him working for 'establishment' institutions. He was closely associated with the BBC's Overseas Service and employed by the British Council's Science Committee. Both organizations found Crowther useful because of his wide, international knowledge of science and scientists. Crowther's political views, and his international aspirations for the British Council's Science Committee, increasingly embroiled him in an institutional conflict with the Royal Society and with its president, Sir Henry Dale, who was also chairman of the British Council's Science Committee. The conflict centred on the management of international scientific relations, a matter close Crowther's heart, and to Dale's. Dale considered that the formal conduct of international scientific relations was the Royal Society's business rather than the British Council's. Crowther disagreed, and eventually resigned from the British Council Science Committee in 1946. The article expands knowledge of Crowther by drawing on archival documents to elucidate a side of his career that is only lightly touched on in his memoirs. It shows that 'Crowther's war' was also an institutional war between the Science Committee of the British Council and the Royal Society. Crowther's unhappy experience of interference by the Royal Society plausibly accounts for a retreat from his pre-war view that institutional science should plan and manage BBC science broadcasts.

Research is usually considered a reliable indicator of the degree of development. Research in a problematic area such as food and nutrition for a given region, should have an impact on scientific production in agreement with the importance of the problem, the research capacity and the available resources for generating such a research. To identify some indicators of Iberoamerican research in nutrition and food. Retrospective study of Iberoamerican scientific production in nutrition and food in the last 25 years. The data were obtained from the bibliographic database Science Citation Index Expanded, Journal Citation Reports Science Edition Database 2011, both included in the Web of Knowledge (Thomson Reuters), and the database of the World Bank. 49,808 papers were registered, the 3.20% of the Health Sciences collection in SCI. The evolution was fitted to an exponential model, N&D (R² 0.962) and FS&T (R² 0.995). The average production in N&D per average population was higher in Spain with 0.659 papers/million. The highest rates of productivity and profitability were found in Guatemala with 12.963 papers/1000 researchers and 1.486 papers/million $ respectively. The average production in FS&T of the different countries per average population was higher in Cuba with 21.624 papers/million. The productivity index was higher in Uruguay with 25.999 papers/thousand researchers. The profitability index was higher in Guatemala with 0.271 papers/million $. There is exponential growth in the two categories studied N&D and FS&T. Productivity and profitability was higher in countries with low R&D (Research & Development) budget.

Current Knowledge on Cannabinoids in Oral Fluid

Lee, Dayong; Huestis, Marilyn A.

2015-01-01

Oral fluid (OF) is a new biological matrix for clinical and forensic drug testing, offering non-invasive and directly observable sample collection reducing adulteration potential, ease of multiple sample collections, lower biohazard risk during collection, recent exposure identification, and stronger correlation with blood than urine concentrations. Because cannabinoids are usually the most prevalent analytes in illicit drug testing, application of OF drug testing requires sufficient scientific data to support sensitive and specific OF cannabinoid detection. This review presents current knowledge on OF cannabinoids, evaluating pharmacokinetic properties, detection windows, and correlation with other biological matrices and impairment from field applications and controlled drug administration studies. In addition, on-site screening technologies, confirmatory analytical methods, drug stability, and effects of sample collection procedure, adulterants, and passive environmental exposure are reviewed. Delta-9-tetrahydrocannabinol OF concentrations could be > 1000 μg/L shortly after smoking, whereas minor cannabinoids are detected at 10-fold and metabolites at 1000-fold lower concentrations. OF research over the past decade demonstrated that appropriate interpretation of test results requires a comprehensive understanding of distinct elimination profiles and detection windows for different cannabinoids, which are influenced by administration route, dose, and drug use history. Thus, each drug testing program should establish cutoff criteria, collection/analysis procedures, and storage conditions tailored to its purposes. Building a scientific basis for OF testing is on-going, with continuing OF cannabinoids research on passive environmental exposure, drug use history, donor physiological conditions, and oral cavity metabolism needed to better understand mechanisms of cannabinoid OF disposition and expand OF drug testing applicability.

Social justice pedagogies and scientific knowledge: Remaking citizenship in the non-science classroom

NASA Astrophysics Data System (ADS)

Lehr, Jane L.

This dissertation contributes to efforts to rethink the meanings of democracy, scientific literacy, and non-scientist citizenship in the United States. Beginning with questions that emerged from action research and exploring the socio-political forces that shape educational practices, it shows why non-science educators who teach for social justice must first recognize formal science education as a primary site of training for (future) non-scientist citizens and then prepare to intervene in the dominant model of scientifically literate citizenship offered by formal science education. This model of citizenship defines (and limits) appropriate behavior for non-scientist citizens as acquiescing to the authority of science and the state by actively demarcating science from non-science, experts from non-experts, and the rational from the irrational. To question scientific authority is to be scientifically illiterate. This vision of 'acquiescent democracy' seeks to end challenges to the authority of science and the state by ensuring that scientific knowledge is privileged in all personal and public decision-making practices, producing a situation in which it becomes natural for non-scientist citizens to enroll scientific knowledge to naturalize oppression within our schools and society. It suggests that feminist and equity-oriented science educators, by themselves, are unable or unwilling to challenge certain assumptions in the dominant model of scientifically literate citizenship. Therefore, it is the responsibility of non-science educators who teach for social justice to articulate oppositional models of non-scientist citizenship and democracy in their classrooms and to challenge the naturalized authority of scientific knowledge in all aspects of our lives. It demonstrates how research in the field of Science & Technology Studies can serve as one resource in our efforts to intervene in the dominant model of scientifically literate citizenship and to support a model of democracy that encourages the critical engagement of and opposition to scientific knowledge and the state.

[Scientific reductionism and social control of mind. Part II].

PubMed

Viniegra Velázquez, Leonardo

In the second part of this essay, the progressive subordination of scientific endeavor and knowledge of business and profit is pointed out. For instance, the way facts are prioritized over concepts and ideas in scientific knowledge can translate into technological innovation, central to enterprise competitiveness and key to social mechanisms of control (military, cybernetic, ideological). Overcoming the scientific reductionism approach indicates recognizing the need to define progress in another way, one that infuses scientific knowledge with real liberating and inquisitive power. Power is essential in the search for a more collaborative, inclusive and pluralistic society where respect for human dignity and care for the ecosystem that we live in are prioritized.

As a gateway for scientific discovery, the Argonne Leadership Computing Facility (ALCF) works hand in hand with the world's best computational scientists to advance research in a diverse span of scientific domains, ranging from chemistry, applied mathematics, and materials science to engineering physics and life sciences. Sponsored by the U.S. Department of Energy's (DOE) Office of Science, researchers are using the IBM Blue Gene/L supercomputer at the ALCF to study and explore key scientific problems that underlie important challenges facing our society. For instance, a research team at the University of California-San Diego/ SDSC is studying the molecular basis ofmore » Parkinson's disease. The researchers plan to use the knowledge they gain to discover new drugs to treat the disease and to identify risk factors for other diseases that are equally prevalent. Likewise, scientists from Pratt & Whitney are using the Blue Gene to understand the complex processes within aircraft engines. Expanding our understanding of jet engine combustors is the secret to improved fuel efficiency and reduced emissions. Lessons learned from the scientific simulations of jet engine combustors have already led Pratt & Whitney to newer designs with unprecedented reductions in emissions, noise, and cost of ownership. ALCF staff members provide in-depth expertise and assistance to those using the Blue Gene/L and optimizing user applications. Both the Catalyst and Applications Performance Engineering and Data Analytics (APEDA) teams support the users projects. In addition to working with scientists running experiments on the Blue Gene/L, we have become a nexus for the broader global community. In partnership with the Mathematics and Computer Science Division at Argonne National Laboratory, we have created an environment where the world's most challenging computational science problems can be addressed. Our expertise in high-end scientific computing enables us to provide guidance for applications that are transitioning to petascale as well as to produce software that facilitates their development, such as the MPICH library, which provides a portable and efficient implementation of the MPI standard--the prevalent programming model for large-scale scientific applications--and the PETSc toolkit that provides a programming paradigm that eases the development of many scientific applications on high-end computers.« less

2013-01-01

We analyze the entire publication database of the American Physical Society generating longitudinal (50 years) citation networks geolocalized at the level of single urban areas. We define the knowledge diffusion proxy, and scientific production ranking algorithms to capture the spatio-temporal dynamics of Physics knowledge worldwide. By using the knowledge diffusion proxy we identify the key cities in the production and consumption of knowledge in Physics as a function of time. The results from the scientific production ranking algorithm allow us to characterize the top cities for scholarly research in Physics. Although we focus on a single dataset concerning a specific field, the methodology presented here opens the path to comparative studies of the dynamics of knowledge across disciplines and research areas.

Protecting Traditional Knowledge Related to Biological Resources: Is Scientific Research Going to Become More Bureaucratized?

PubMed

Reddy, Prashant; Lakshmikumaran, Malathi

2015-06-22

For the past several decades, there has been a world debate on the need for protecting traditional knowledge. A global treaty appears to be a distant reality. Of more immediate concern are the steps taken by the global community to protect access to biological resources in the name of protecting traditional knowledge. The Indian experience with implementing the Convention on Biological Diversity has created substantial legal uncertainty in collaborative scientific research between Indians and foreigners apart from bureaucratizing the entire process of scientific research, especially with regard to filing of applications for intellectual property rights. The issue therefore is whether the world needs to better balance the needs of the scientific community with the rights of those who have access to traditional knowledge.

An inventory of the theses on hepatitis of the Faculdade de Medicina of the Universidade Federal do Rio de Janeiro between 1837 and 2000 is presented. The analysis indicates the potential and limits for discussion of the evolutionary framework of scientific knowledge on these health problems in Brazil. The theories are also discussed in light of their scientific reference points and the technological and social changes that influenced them. The landmarks in medical education and knowledge about hepatitis are identified and categorized, considering that the theses reveal at the very least the state of the art on the subject. The study makes it possible to explore the foundations upon which the scientific knowledge on hepatitis were built and indicate possibilities for research in the reconstruction of scientific knowledge of other health problems.

The influence of the history of science course on pre-service science teachers' understanding of the nature of science concepts

NASA Astrophysics Data System (ADS)

Akcay, Behiye

The purpose of this study was to investigate the influence of a history of science course on pre-service science teachers' understanding of the nature of science concepts. Subjects in the study were divided in two groups: (1) students who enrolled in only in the history of science course, (2) students who enrolled both the meaning of science and the history of science courses. An interpretative-descriptive approach and constant comparative analysis were used to identify similarities and differences among pre-service teachers' views about nature of scientific knowledge prior to and after the history of science course. The results of this study indicate that explicitly addressing certain aspects of the nature of science is effective in promoting adequate understanding of the nature of science for pre-service science teachers. Moreover, the results indicate that a student's prior experience with the history of science helps to improve their understanding of the history and nature of science. The history of science course helped pre-service teachers to develop the following views which are parallel with these advocated in both the Benchmarks (AAAS, 1993) and the National Science Education Standards (NRC, 1996) concerning the nature of scientific knowledge: (1) Scientific knowledge is empirically based and an ongoing process of experimentation, investigation, and observation. (2) Science is a human endeavor. (3) People from different cultures, races, genders, and nationality contribute to science. (4) Scientific knowledge is not based on myths, personal beliefs, and religious values. (5) Science background and prior knowledge have important roles for scientific investigations. (6) Scientific theories and laws represent different kinds of knowledge. (7) Science is affected by political, social, and cultural values. (8) Creativity and imagination are used during all stages of scientific investigations. (9) Theories change because of new evidence and new views of existing data as well as advances in technology. (10) Theories have significant roles in generating future research questions. (11) Adequate understanding of differences between observations and inferences develop from considering the history of science. (12) There is no single universal step-by-step scientific method. (13) Learning about the nature of scientific knowledge helps students to become scientifically literate.

Scaffolding Student Learning in the Discipline-Specific Knowledge through Contemporary Science Practices: Developing High-School Students' Epidemiologic Reasoning through Data Analysis

NASA Astrophysics Data System (ADS)

Oura, Hiroki

Science is a disciplined practice about knowing puzzling observations and unknown phenomena. Scientific knowledge of the product is applied to develop technological artifacts and solve complex problems in society. Scientific practices are undeniably relevant to our economy, civic activity, and personal lives, and thus public education should help children acquire scientific knowledge and recognize the values in relation to their own lives and civil society. Likewise, developing scientific thinking skills is valuable not only for becoming a scientist, but also for becoming a citizen who is able to critically evaluate everyday information, select and apply only the trustworthy, and make wise judgments in their personal and cultural goals as well as for obtaining jobs that require complex problem solving and creative working in the current knowledge-based economy and rapid-changing world. To develop students' scientific thinking, science instruction should focus not only on scientific knowledge and inquiry processes, but also on its epistemological aspects including the forms of causal explanations and methodological choices along with epistemic aims and values under the social circumstances in focal practices. In this perspective, disciplinary knowledge involves heterogeneous elements including material, cognitive, social, and cultural ones and the formation differs across practices. Without developing such discipline-specific knowledge, students cannot enough deeply engage in scientific "practices" and understand the true values of scientific enterprises. In this interest, this dissertation explores instructional approaches to make student engagement in scientific investigations more authentic or disciplinary. The present dissertation work is comprised of three research questions as stand-alone studies written for separate publication. All of the studies discuss different theoretical aspects related to disciplinary engagement in epidemiologic inquiry and student development in epidemiologic reasoning. The first chapter reviews literature on epistemological instruction and explores theoretical frameworks for epistemically-guided instruction. The second chapter explores methodological strategies to elicit students' disciplinary understanding and demonstrates an approach with a case study in which students engaged in a curriculum unit for an epidemiologic investigation. The last chapter directs the focus into scientific reasoning and demonstrates how the curriculum unit and its scaffolds helped students develop epidemiologic reasoning with a focus on population-based reasoning.

Multiple barriers to knowledge translation in medicine have been identified (ranging from information overload to abstraction of models), leading to important implementation gaps. This study aimed at assessing the suggestions of practicing physicians for possible improvements of knowledge translation (KT) effectiveness into clinical practice. We used a mixed methods design. French- German- and Italian-speaking general practitioners, psychiatrists, orthopaedic surgeons, cardiologists, and diabetologists practicing in Switzerland were interrogated through semi-structured interviews, focus group discussions, and an online survey. A total of 985 physicians from three regions of Switzerland participated in the online survey, whereas 39 participated in focus group discussions and 14 in face-to-face interviews. Physicians expressed limitations and difficulties related to KT into their daily practice. Several barriers were identified, including influence and pressure of pharmaceutical companies, non-publication of negative results, mismatch between guidelines and practice, education gaps, and insufficient collaboration between research and practice. Suggestions to overcome barriers were improving education concerning the evaluation of scientific publications, expanding applicability of guidelines, having free and easy access to independent journals, developing collaborations between research and practice, and creating tools to facilitate access to medical information. Our study provides suggestions for improving KT into daily medical practice, matching the views, needs and preferences of practicing physicians. Responding to suggestions for improvements brought up by physicians may lead to better knowledge translation, higher professional satisfaction, and better healthcare outcomes.

Collaborative Science with Indigenous Knowledge for Climate Solutions: Why, How, and with Whom?

The inherent complexity of climate change requires diverse perspectives to understand and respond to its impacts. The Rising Voices: Collaborative Science with Indigenous Knowledge for Climate Solutions (Rising Voices) program represents a growing network of engaged Indigenous and non-Indigenous scientists committed to cross-cultural and collaborative research and activities to understand and mitigate the impacts of extreme weather and climate change. Five annual Rising Voices workshops have occurred since 2013, engaging hundreds of participants from across Tribal communities, the United States, and internationally over the years. Housed at the National Center for Atmospheric Research, Rising Voices aims to expand how diversity is understood in atmospheric science, to include intellectual diversity stemming from distinct cultural backgrounds. It envisions collaborative research that brings together Indigenous knowledges and science with Western climate and weather sciences in a respectful and inclusive manner to achieve culturally relevant and scientifically robust climate and weather adaptation solutions. The premise of the program and the research and collaborations it produces is that there is an opportunity cost to not involving diverse knowledge systems and observations from varied cultural backgrounds in addressing climate change. We cannot afford that cost given the challenges ahead. This poster presents some of the protocols, methods, challenges, and outcomes of cross-cultural research between Western and Indigenous scientists and communities from across the United States. It also presents some of the recommendations that have emerged from Rising Voices workshops over the past five years.

The tempo and mode of human knowledge expansion is an enduring yet poorly understood topic. Through a temporal network analysis of three decades of discoveries of protein interactions and genetic interactions in baker's yeast, we show that the growth of scientific knowledge is exponential over time and that important subjects tend to be studied earlier. However, expansions of different domains of knowledge are highly heterogeneous and episodic such that the temporal turnover of knowledge hubs is much greater than expected by chance. Familiar subjects are preferentially studied over new subjects, leading to a reduced pace of innovation. While research is increasingly done in teams, the number of discoveries per researcher is greater in smaller teams. These findings reveal collective human behaviors in scientific research and help design better strategies in future knowledge exploration. PMID:19300476

Mental disorder is harmful to human health, effects social life seriously and still brings a heavy burden for countries all over the world. Scientific collaboration has become the indispensable choice for progress in the field of biomedicine. However, there have been few scientific publications on scientific collaboration in psychiatry research so far. The aim of this study was to measure the activities of scientific collaboration in psychiatry research at the level of authors, institutions and countries. We retrieved 36557 papers about psychiatry from Science Ciation Index Expanded (SCI-Expanded) in web of science. Additionally, some methods such as social network analysis (SNA), K-plex analysis and Core-Periphery were used in this study. Collaboration has been increasing at the level of authors, institutions and countries in psychiatry in the last ten years. We selected the top 100 prolific authors, institutions and 30 countries to construct collaborative map respectively. Freedman, R and Seidman, LJ were the central authors, Harvard university was the central institution and the USA was the central country of the whole network. Notably, the rate of economic development of countries affected collaborative behavior. The results show that we should encourage multiple collaboration types in psychiatry research as they not only help researchers to master the current research hotspots but also provide scientific basis for clinical research on psychiatry and suggest policies to promote the development of this area.

Access to scientific knowledge in the context of CITES is a crucial issue. The effectiveness of the text is indeed largely based on adequate scientific knowledge of CITES species. This is a major challenge: more than 30,000 species and 178 member states are involved. The issue of expertise, however, is not really addressed by the Convention. The question was left to the consideration of the COP. Therefore, the COP has created two ad hoc scientific committees: the Plants Committee and the Animals Committee, conferring upon them an ambitious mandate. The article addresses some important issues at stake which are linked to institutional questions, as well as the mixed record after twenty-five years of practice.

Scientific editors are responsible for deciding which articles to publish in their journals. However, we have not found documentation of their required knowledge, skills, and characteristics, or the existence of any formal core competencies for this role. We describe the development of a minimum set of core competencies for scientific editors of biomedical journals. The 14 key core competencies are divided into three major areas, and each competency has a list of associated elements or descriptions of more specific knowledge, skills, and characteristics that contribute to its fulfillment. We believe that these core competencies are a baseline of the knowledge, skills, and characteristics needed to perform competently the duties of a scientific editor at a biomedical journal.

From Comparison Between Scientists to Gaining Cultural Scientific Knowledge. Leonardo and Galileo

NASA Astrophysics Data System (ADS)

Galili, Igal

2016-03-01

Physics textbooks often present items of disciplinary knowledge in a sequential order of topics of the theory under instruction. Such presentation is usually univocal, that is, isolated from alternative claims and contributions regarding the subject matter in the pertinent scientific discourse. We argue that comparing and contrasting the contributions of scientists addressing similar or the same subject could not only enrich the picture of scientific enterprise, but also possess a special appealing power promoting genuine understanding of the concept considered. This approach draws on the historical tradition from Plutarch in distant past and Koyré in the recent history and philosophy of science. It gains a new support in the discipline-culture structuring of the physics curriculum, seeking cultural content knowledge (CCK) of the subject matter. Here, we address two prominent individuals of Italian Renaissance, Leonardo and Galileo, in their dealing with issues relevant for introductory science courses. Although both figures addressed similar subjects of scientific content, their products were essentially different. Considering this difference is educationally valuable, illustrating the meaning of what students presently learn in the content knowledge of mechanics, optics and astronomy, as well as the nature of science and scientific knowledge.

Narratives of location: School science identities and scientific discourse among Navajo women at the University of New Mexico

NASA Astrophysics Data System (ADS)

Brandt, Carol B.

This research examines the interplay of scientific discourse and students' sense of self among four Navajo (Dine) women as they major in science at a university in the southwestern United States. This dissertation research is an ethnographic case study of Navajo women as they were completing their final year of undergraduate study in the life sciences at a university. How do Navajo women express their identity in Western science at the university? What role does scientific discourse play in this process? This research employs a feminist poststructural approach to language and expands the way discourse has typically been addressed in science education. I expand the notion of discourse through poststructuralism by recognizing the co-constitutive role of language in fashioning realities and generating meaning. Data sources in this study included transcripts from one-on-one interviews, electronic correspondence (e-mail), observations of social contexts on campus, students' writing for science courses, university policy statements, departmental outcomes assessments, web profiles of student research in science, and a researcher's reflective journal. This study took place beginning in January 2002 and continued through May of 2003 at the University of New Mexico. After completing the thematic (constant comparative analysis) and an analysis of metaphors, I "retold" or "restoried" the narratives collected during interviews. In the cross case analysis, I compared each participant's description of those discursive spaces that afforded engagement with science, and those locations where their awareness of academic language was heightened in a process of metadiscourse. I identified these spaces as locations of possibility in which students and their mentors (or instructors) valued connected knowing, acknowledged each other's history, culture, and knowledge, and began speaking to each other subject-to-subject to challenge normative views of schooling. The participants in this research located spaces in which they authored themselves: study groups, a research project on invasive plants, the American Indian Medial Association, and a community college. The women in this study selectively accommodated elements of Western science that were consistent with their identity as they positioned themselves in service to family, community, and tribe, and also sought positions beyond the objectified gaze of the institution.

It is control that turns scientific knowledge into useful technology: in physics and engineering it provides a systematic way for driving a dynamical system from a given initial state into a desired target state with minimized expenditure of energy and resources. As one of the cornerstones for enabling quantum technologies, optimal quantum control keeps evolving and expanding into areas as diverse as quantum-enhanced sensing, manipulation of single spins, photons, or atoms, optical spectroscopy, photochemistry, magnetic resonance (spectroscopy as well as medical imaging), quantum information processing and quantum simulation. In this communication, state-of-the-art quantum control techniques are reviewed and put into perspective by a consortium of experts in optimal control theory and applications to spectroscopy, imaging, as well as quantum dynamics of closed and open systems. We address key challenges and sketch a roadmap for future developments.

GRACEnet (Greenhouse gas Reduction through Agricultural Carbon Enhancement network) was conceived to build upon ongoing USDA Agricultural Research Service (ARS) research to improve soil productivity, while addressing the challenges and opportunities of interest in C sequestration from a climate change perspective. The vision for GRACEnet was and remains: Knowledge and information used to implement scientifically based agricultural management practices from the field to national policy scales on C sequestration, greenhouse gas (GHG) emissions, and environmental benefits. The national focus of GRACEnet uses a standardized approach by ARS laboratories and university and land manager (e.g. farmer and rancher) cooperators to assess C sequestration and GHG emission from different crop and grassland systems. Since 2002, GRACEnet has significantly expanded GHG mitigation science and delivered usable information to agricultural research and policy organizations. Recent developments suggest GRACEnet will have international impact by contributing leadership and technical guidance for the Global Research Alliance on Agricultural Greenhouse Gases.

Implicit Learning in Science: Activating and Suppressing Scientific Intuitions to Enhance Conceptual Change

NASA Astrophysics Data System (ADS)

Wang, Jeremy Yi-Ming

This dissertation examines the thesis that implicit learning plays a role in learning about scientific phenomena, and subsequently, in conceptual change. Decades of research in learning science demonstrate that a primary challenge of science education is overcoming prior, naive knowledge of natural phenomena in order to gain scientific understanding. Until recently, a key assumption of this research has been that to develop scientific understanding, learners must abandon their prior scientific intuitions and replace them with scientific concepts. However, a growing body of research shows that scientific intuitions persist, even among science experts. This suggests that naive intuitions are suppressed, not supplanted, as learners gain scientific understanding. The current study examines two potential roles of implicit learning processes in the development of scientific knowledge. First, implicit learning is a source of cognitive structures that impede science learning. Second, tasks that engage implicit learning processes can be employed to activate and suppress prior intuitions, enhancing the likelihood that scientific concepts are adopted and applied. This second proposal is tested in two experiments that measure training-induced changes in intuitive and conceptual knowledge related to sinking and floating objects in water. In Experiment 1, an implicit learning task was developed to examine whether implicit learning can induce changes in performance on near and far transfer tasks. The results of this experiment provide evidence that implicit learning tasks activate and suppress scientific intuitions. Experiment 2 examined the effects of combining implicit learning with traditional, direct instruction to enhance explicit learning of science concepts. This experiment demonstrates that sequencing implicit learning task before and after direct instruction has different effects on intuitive and conceptual knowledge. Together, these results suggest a novel approach for enhancing learning for conceptual change in science education.

Although one role of computers in science education is to help students learn specific science concepts, computers are especially intriguing as a vehicle for fostering the development of epistemological knowledge about the nature of scientific knowledge--what it means to "know" in a scientific sense (diSessa, 1985). In this vein, the…

Application of Ontologies for Big Earth Data

Connected data is smarter data! Earth Science research infrastructure must do more than just being able to support temporal, geospatial discovery of satellite data. As the Earth Science data archives continue to expand across NASA data centers, the research communities are demanding smarter data services. A successful research infrastructure must be able to present researchers the complete picture, that is, datasets with linked citations, related interdisciplinary data, imageries, current events, social media discussions, and scientific data tools that are relevant to the particular dataset. The popular Semantic Web for Earth and Environmental Terminology (SWEET) ontologies is a collection of ontologies and concepts designed to improve discovery and application of Earth Science data. The SWEET ontologies collection was initially developed to capture the relationships between keywords in the NASA Global Change Master Directory (GCMD). Over the years this popular ontologies collection has expanded to cover over 200 ontologies and 6000 concepts to enable scalable classification of Earth system science concepts and Space science. This presentation discusses the semantic web technologies as the enabling technology for data-intensive science. We will discuss the application of the SWEET ontologies as a critical component in knowledge-driven research infrastructure for some of the recent projects, which include the DARPA Ontological System for Context Artifact and Resources (OSCAR), 2013 NASA ACCESS Virtual Quality Screening Service (VQSS), and the 2013 NASA Sea Level Change Portal (SLCP) projects. The presentation will also discuss the benefits in using semantic web technologies in developing research infrastructure for Big Earth Science Data in an attempt to "accommodate all domains and provide the necessary glue for information to be cross-linked, correlated, and discovered in a semantically rich manner."

The role of the media in the science-policy nexus. Some critical reflections based on an analysis of the Belgian drug policy debate (1996-2003).

Tieberghien, Julie

Drug policy is one of the most polarised subjects of public debate and media coverage, which frequently tend to be dramatic and event-centred. Although the role of the media in directing the drug discourse is widely acknowledged, limited research has been conducted in examining the particular role of the media in the science-policy nexus. We sought to determine how the (mis)representation of scientific knowledge in the media may, or may not, have an impact on the contribution of scientific knowledge to the drug-policy making process. Using a case study of the Belgian drug-policy debates between 1996 and 2003, we conducted a discourse analysis of specially selected 1067 newspaper articles and 164 policy documents. Our analysis focused on: textual elements that feature intra-discourse differences, how players and scientific knowledge are represented in the text, the arguments used and claims made, and the various types of research utilisation. Media discourse strongly influenced the public's and policy makers' understanding as well as the content of the Belgian drug policy debate between 1996 and 2003. As a major source of scientific knowledge, media coverage supported the 'enlightenment' role of scientific knowledge in the policy-making process by broadening and even determining frames of reference. However, as the presentation of scientific knowledge in the media was often inaccurate or distorted due to the lack of contextual information or statistical misinformation, the media may also support the selective utilisation of scientific knowledge. Many challenges as well as opportunities lie ahead for researchers who want to influence the policy-making process since most research fails to go beyond academic publications. Although media is a valuable linking mechanism between science and policy, by no means does it provide scientists with a guarantee of a more 'evidence-based' drug policy.

Historically, radio observatories have placed the onus of calibrating and imaging data on the observer, thus restricting their user base to those already initiated into the mysteries of radio data or those willing to develop these skills. To expand its user base, the Atacama Large Millimeter/submillimeter Array (ALMA) has a high- level directive to calibrate users' data and, ultimately, to deliver scientifically usable images or cubes to principle investigators (PIs). Although an ALMA calibration pipeline is in place, all delivered images continue to be produced for the PI by hand. In this talk, I will describe on-going efforts at the Northern American ALMA Science Center to produce more uniform imaging products that more closely meet the PI science goals and provide better archival value. As a first step, the NAASC imaging group produced a simple imaging template designed to help scientific staff produce uniform imaging products. This script allowed the NAASC to maximize the productivity of data analysts with relatively little guidance by the scientific staff by providing a step-by-step guide to best practices for ALMA imaging. Finally, I will describe the role of the manually produced images in verifying the imaging pipeline and the on-going development of said pipeline. The development of the imaging template, while technically simple, shows how small steps toward unifying processes and sharing knowledge can lead to large gains for science data products.

To ontologise or not to ontologise: An information model for a geospatial knowledge infrastructure

A geospatial knowledge infrastructure consists of a set of interoperable components, including software, information, hardware, procedures and standards, that work together to support advanced discovery and creation of geoscientific resources, including publications, data sets and web services. The focus of the work presented is the development of such an infrastructure for resource discovery. Advanced resource discovery is intended to support scientists in finding resources that meet their needs, and focuses on representing the semantic details of the scientific resources, including the detailed aspects of the science that led to the resource being created. This paper describes an information model for a geospatial knowledge infrastructure that uses ontologies to represent these semantic details, including knowledge about domain concepts, the scientific elements of the resource (analysis methods, theories and scientific processes) and web services. This semantic information can be used to enable more intelligent search over scientific resources, and to support new ways to infer and visualise scientific knowledge. The work describes the requirements for semantic support of a knowledge infrastructure, and analyses the different options for information storage based on the twin goals of semantic richness and syntactic interoperability to allow communication between different infrastructures. Such interoperability is achieved by the use of open standards, and the architecture of the knowledge infrastructure adopts such standards, particularly from the geospatial community. The paper then describes an information model that uses a range of different types of ontologies, explaining those ontologies and their content. The information model was successfully implemented in a working geospatial knowledge infrastructure, but the evaluation identified some issues in creating the ontologies.

Scientific Literacy in Food Education: Gardening and Cooking in School

NASA Astrophysics Data System (ADS)

Strohl, Carrie A.

Recent attention to socio-scientific issues such as sustainable agriculture, environmental responsibility and nutritional health has spurred a resurgence of public interest in gardening and cooking. Seen as contexts for fostering scientific literacy---the knowledge domains, methodological approaches, habits of mind and discourse practices that reflect one's understanding of the role of science in society, gardening and cooking are under-examined fields in science education, in part, because they are under-utilized pedagogies in school settings. Although learning gardens were used historically to foster many aspects of scientific literacy (e.g., cognitive knowledge, norms and methods of science, attitudes toward science and discourse of science), analysis of contemporary studies suggests that science learning in gardens focuses mainly on science knowledge alone. Using multiple conceptions of scientific literacy, I analyzed qualitative data to demonstrate how exploration, talk and text fostered scientific literacy in a school garden. Exploration prompted students to engage in scientific practices such as making observations and constructing explanations from evidence. Talk and text provided background knowledge and accurate information about agricultural, environmental and nutritional topics under study. Using a similar qualitative approach, I present a case study of a third grade teacher who explicitly taught food literacy through culinary arts instruction. Drawing on numerous contextual resources, this teacher created a classroom community of food practice through hands-on cooking lessons, guest chef demonstrations, and school-wide tasting events. As a result, she promoted six different types of knowledge (conceptual, procedural, dispositional, sensory, social, and communal) through leveraging contextual resources. This case study highlights how food literacy is largely contingent on often-overlooked mediators of food literacy: the relationships between participants, the activity, and the type of knowledge invoked. Scientific literacy in food education continues to be a topic of interest in the fields of public health and of sustainable agriculture, as well as to proponents of the local food movement. This dissertation begins to map a more cohesive and comprehensive approach to gardening and cooking implementation and research in school settings.

Contemporary HIV/AIDS research: Insights from knowledge management theory.

PubMed

Callaghan, Chris William

2017-12-01

Knowledge management as a field is concerned with the management of knowledge, including the management of knowledge in research processes. Knowledge management theory has the potential to support research into problems such as HIV, antibiotic resistance and others, particularly in terms of aspects of scientific research related to the contribution of social science. To date, however, these challenges remain with us, and theoretical contributions that can complement natural science efforts to eradicate these problems are needed. This paper seeks to offer a theoretical contribution grounded in Kuhn's paradigm theory of innovation, and in the argument by Lakatos that scientific research can be fundamentally non-innovative, which suggests that social science aspects of knowledge creation may hold the key to more effective biomedical innovation. Given the consequences of ongoing and emerging global crises, and the failure of knowledge systems of scientific research to solve such problems outright, this paper provides a review of theory and literature arguing for a new paradigm in scientific research, based on the development of global systems to maximise research collaborations. A global systems approach effectively includes social science theory development as an important complement to the natural sciences research process. Arguably, information technology and social media technology have developed to the point at which solutions to knowledge aggregation challenges can enable solutions to knowledge problems on a scale hitherto unimaginable. Expert and non-expert crowdsourced inputs can enable problem-solving through exponentially increasing problem-solving inputs, using the 'crowd,' thereby increasing collaborations dramatically. It is argued that these developments herald a new era of participatory research, or a democratisation of research, which offers new hope for solving global social problems. This paper seeks to contribute to this end, and to the recognition of the important role of social theory in the scientific research process.

The nearly universal link between the age of past knowledge and tomorrow’s breakthroughs in science and technology: The hotspot

Scientists and inventors can draw on an ever-expanding literature for the building blocks of tomorrow’s ideas, yet little is known about how combinations of past work are related to future discoveries. Our analysis parameterizes the age distribution of a work’s references and revealed three links between the age of prior knowledge and hit papers and patents. First, works that cite literature with a low mean age and high age variance are in a citation “hotspot”; these works double their likelihood of being in the top 5% or better of citations. Second, the hotspot is nearly universal in all branches of science and technology and is increasingly predictive of a work’s future citation impact. Third, a scientist or inventor is significantly more likely to write a paper in the hotspot when they are coauthoring than whey they are working alone. Our findings are based on all 28,426,345 scientific papers in the Web of Science, 1945–2013, and all 5,382,833 U.S. patents, 1950–2010, and reveal new antecedents of high-impact science and the link between prior literature and tomorrow’s breakthrough ideas.

We developed and evaluated a novel National Institutes of Health-sponsored Research and Mentorship Program for African American and Hispanic medical students embedded within the international, multisite HIV Vaccine Trials Network, and explored its impact on scientific knowledge, acquired skills, and future career plans. Scholars conducted social, behavioral, clinical, or laboratory-based research projects with HIV Vaccine Trials Network investigators over 8 to 16 weeks (track 1) or 9 to 12 months (track 2). We conducted an in-depth, mixed-methods evaluation of the first 2 cohorts (2011-2013) to identify program strengths, areas for improvement, and influence on professional development. A pre-post program assessment demonstrated increases in self-reported knowledge, professional skills, and interest in future HIV vaccine research. During in-depth interviews, scholars reported that a supportive, centrally administered program; available funding; and highly involved mentors and staff were keys to the program's early success. A multicomponent, mentored research experience that engages medical students from underrepresented communities and is organized within a clinical trials network may expand the pool of diverse public health scientists. Efforts to sustain scholar interest over time and track career trajectories are warranted.

Purpose of review The purpose of this study is to review recent scientific advances relating to the natural history, cause, treatment and serum and imaging biomarkers of inclusion body myositis (IBM). Recent findings Several theories regarding the aetiopathogenesis of IBM are being explored and new therapeutic approaches are being investigated. New diagnostic criteria have been proposed, reflecting the knowledge that the diagnostic pathological findings may be absent in patients with clinically typical IBM. The role of MRI in IBM is expanding and knowledge about pathological biomarkers is increasing. The recent description of autoantibodies to cytosolic 5′ nucleotidase 1A in patients with IBM is a potentially important advance that may aid early diagnosis and provides new evidence regarding the role of autoimmunity in IBM. Summary IBM remains an enigmatic and often misdiagnosed disease. The pathogenesis of the disease is still not fully understood. To date, pharmacological treatment trials have failed to show clear efficacy. Future research should continue to focus on improving understanding of the pathophysiological mechanisms of the disease and on the identification of reliable and sensitive outcome measures for clinical trials. IBM is a rare disease and international multicentre collaboration for trials is important to translate research advances into improved patient outcomes. PMID:24067381

Echinococcus multilocularis in North America: the great unknown

2014-01-01

Over the last decade, studies have begun to shed light on the distribution and genetic characterization of Echinococcus multilocularis, the causative agent of alveolar echinococcosis (AE), in North America. Recent findings indicate that the parasite is likely expanding its range in the central region of the United States and Canada and that invasions of European strains might have occurred. In our review, we present the available data on E. multilocularis infections in wild and domestic animals and humans in North America and emphasize the lack of knowledge on the distribution of the parasite in wild and domestic hosts. Furthermore, we stress the need to better understand the complexity of host communities and their roles in shaping the transmission and distribution of the parasite. We hypothesize that a lack of knowledge about AE by North American physicians might result in the misdiagnosis of cases and an underestimation of disease incidence. The endemic presence of the parasite in urban areas and a recent human case in Alberta, Canada, suggest that the scientific community may need to reconsider the local public health risks, re-assess past cases that might have been overlooked and increase surveillance efforts to identify new cases of human AE.

Criminalizing knowledge: the perverse implications of the intended use regulations of off-label promotion prosecutions.

Gentry, Gregory

2009-01-01

Your company has spent months designing a compliance program and training your sales representatives. They know never to mention the off-label uses of your product. If they are asked about the off-label uses by the physician they are detailing, they know to forward those inquiries to the scientific liaisons at headquarters. But, could your company still be in legal jeopardy simply because it knows that the product is being used for an off-label purpose? This article attempts to track the Food and Drug Administration's (FDA's) shifting interpretation of its "intended use" regulations, from focusing entirely on the statements of the manufacturers to focusing on the knowledge of the industry, indeed, of the consumers of products, in determining the true intended use of a product. It will look at several recent attempts by FDA to use that new interpretation of the regulations to expand its power: to regulate tobacco and to require pediatric indications for any new drug. Finally, it will look at several recent examples of how this new interpretation has manifested in actions by FDA and the Department of Justice (DOJ).

The best innovations in cancer communication do not necessarily achieve uptake by researchers, public health and clinical practitioners, and policy makers. This paper describes design activities that can be applied and combined for the purpose of spreading effective cancer communication innovations. A previously developed Push-Pull-Infrastructure Model is used to organize and highlight the types of activities that can be deployed during the design phase of innovations. Scientific literature about the diffusion of innovations, knowledge utilization, marketing, public health, and our experiences in working to spread effective practices, programs, and policies are used for this purpose. Attempts to broaden the reach, quicken the uptake, and facilitate the use of cancer communication innovations can apply design activities to increase the likelihood of diffusion. Some simple design activities hold considerable promise for improving dissemination and subsequent diffusion. Augmenting current dissemination practices with evidence-based concepts from diffusion science, marketing science, and knowledge utilization hold promise for improving results by eliciting greater market pull. Inventors and change agencies seeking to spread cancer communication innovations can experience more success by explicit consideration of design activities that reflect an expanded version of the Push-Pull-Infrastructure Model.

The NASA U.S. Spacesuit Knowledge Capture (SKC) Program continues to capture, share, and archive significant spacesuit-related knowledge with engineers and other technical staff and invested entities. Since its 2007 inception, the SKC Program has hosted and recorded more than 75 events. By the end of Fiscal Year (FY) 2015, 40 of these were processed and uploaded to a publically accessible NASA Web site where viewers can expand their knowledge about the spacesuit's evolution, known capabilities and limitations, and lessons learned. Sharing this knowledge with entities beyond NASA can increase not only more people's understanding of the technical effort and importance involved in designing a spacesuit, it can also expand the interest and support in this valuable program that ensures significant knowledge is retained and accessible. This paper discusses the FY 2015 SKC events, the release and accessibility of the approved events, and the program's future plans.

The NASA U.S. Spacesuit Knowledge Capture (SKC) Program continues to capture, share, and archive significant spacesuit-related knowledge with engineers and other technical staff and invested entities. Since its 2007 inception, the SKC Program has hosted and recorded more than 65 events. By the end of Fiscal Year (FY) 2015, 40 of these were processed and uploaded to a publically accessible NASA Web site where viewers can expand their knowledge about the spacesuit's evolution, known capability and limitations, and lessons learned. Sharing this knowledge with entities beyond NASA can increase not only more people's understanding of the technical effort and importance involved in designing a spacesuit, it can also expand the interest and support in this valuable program that ensures significant knowledge is retained and accessible. This paper discusses the FY 2015 SKC events, the release and accessibility of the approved events, and the program's future plans.

Introduction of a Framework for Dynamic Knowledge Representation of the Control Structure of Transplant Immunology: Employing the Power of Abstraction with a Solid Organ Transplant Agent-Based Model

PubMed Central

An, Gary

2015-01-01

Agent-based modeling has been used to characterize the nested control loops and non-linear dynamics associated with inflammatory and immune responses, particularly as a means of visualizing putative mechanistic hypotheses. This process is termed dynamic knowledge representation and serves a critical role in facilitating the ability to test and potentially falsify hypotheses in the current data- and hypothesis-rich biomedical research environment. Importantly, dynamic computational modeling aids in identifying useful abstractions, a fundamental scientific principle that pervades the physical sciences. Recognizing the critical scientific role of abstraction provides an intellectual and methodological counterweight to the tendency in biology to emphasize comprehensive description as the primary manifestation of biological knowledge. Transplant immunology represents yet another example of the challenge of identifying sufficient understanding of the inflammatory/immune response in order to develop and refine clinically effective interventions. Advances in immunosuppressive therapies have greatly improved solid organ transplant (SOT) outcomes, most notably by reducing and treating acute rejection. The end goal of these transplant immune strategies is to facilitate effective control of the balance between regulatory T cells and the effector/cytotoxic T-cell populations in order to generate, and ideally maintain, a tolerant phenotype. Characterizing the dynamics of immune cell populations and the interactive feedback loops that lead to graft rejection or tolerance is extremely challenging, but is necessary if rational modulation to induce transplant tolerance is to be accomplished. Herein is presented the solid organ agent-based model (SOTABM) as an initial example of an agent-based model (ABM) that abstractly reproduces the cellular and molecular components of the immune response to SOT. Despite its abstract nature, the SOTABM is able to qualitatively reproduce acute rejection and the suppression of acute rejection by immunosuppression to generate transplant tolerance. The SOTABM is intended as an initial example of how ABMs can be used to dynamically represent mechanistic knowledge concerning transplant immunology in a scalable and expandable form and can thus potentially serve as useful adjuncts to the investigation and development of control strategies to induce transplant tolerance.

2006-09-01

Difficulties in students’ understanding of the spherical model of the Earth have been shown in previous studies. One of the reasons for these difficulties lies in beliefs and preliminary knowledge that hinder the interpretation of the scientific knowledge, the other reason may lie in the low level of verbal and visuo-spatial abilities. The study aims to investigate the effect of verbal and visuo-spatial abilities, but also that of preliminary knowledge on the later development of the knowledge of the Earth in school. 176 schoolchildren (96 boys and 80 girls) from five schools were tested; the mean age of the children during the first interview was seven years and eight months. All students were interviewed twice in grades 1 and 2, before and after they had learnt the topic in school. Factual, scientific and synthetic knowledge was assessed. The facilitative effect of visuo-spatial and verbal abilities and preliminary factual and scientific knowledge on students’ knowledge of astronomy after having learnt the topic in school was shown. In contrast, the hindering effect of synthetic knowledge was not found.

The Anatomy Department at Tel-Aviv University Medical School offers its students an elective course of 26 didactic hours on human evolution. The course is open to students from all faculties, who must fulfill all academic requirements, without a prerequisite of a background in anatomy. Approximately 120 students attend annually, a third of them are nonmedical students who major in philosophy, archeology, and sociology. This article discusses the course's contributions to students' understanding of a scientific concept that a scientific theory can be contradicted by new evidence, because facts govern science. Also, research methods of applying scientific principles establish the understanding of the human body, which evidently contributes to health and medicine. In the classes, the students are divided into mini-groups of 2-3 students, while the lecturer moves among students to examine fossils. In addition, analogies, open-discussions, and explanations accompany the tangible experiences. The lecturer of the course is an experienced anthropologist-anatomist researcher. He is a role-model and a mentor, sharing with the students his belief that a scientist should be persistent in his research to overcome difficult circumstances. Students, regardless of their backgrounds, express high appreciation of the course in their feedback questionnaires. The message conveyed by this course is that not only knowledge counts but also its integration with scientific principles. This course teaches us that science can bring students from different areas to study together and share ideas. In conclusion, this is a unique course in the eyes of the faculty and students alike.

In all the fields of earth and environmental science, the pursuit of a research question on a topic that has captured one's interest represents both an exciting challenge and a serious responsibility. There is currently a great need to expand knowledge of many aspects of our changing world. Nonetheless, the scientific community, like other communities, has its own culture and values that can seem to be at odds with one's personal motivation and values. Further, it can seem that scientific institutions are organized in a manner to present a set of hurdles that must be cleared in the pursuit of research questions and dissemination of results. One strategy as a scientist is to deal with this community and its cultural constraints on one's own terms. For example, the scientific community has become necessarily focused on review and assessment in the distribution of limited research resources. Further, rankings to assess impact of journals and tracking of citations are being used commonly in assessing success in research. In mentoring interactions there is an opportunity to share experiences of persistence through the publication process, as new findings cannot make a difference unless they are published. One way to deal with the flaws in these metrics is to remain attuned to one's own sense of the intrinsic value and excitement of the research question being studied, and not lose track of the value of forward progress on tough questions, progress that may not be suitable for the high profile journals with a broad scope. In mentoring, it may be as important to convey that it is possible to have a rewarding scientific career by actively choosing when to compromise, to take risks or to go your own way, as to help students learn research techniques. Possible starting points for such discussions are the old spaghetti westerns starring Clint Eastwood.

Applying the Scientific Method of Cybersecurity Research

Tardiff, Mark F.; Bonheyo, George T.; Cort, Katherine A.

The cyber environment has rapidly evolved from a curiosity to an essential component of the contemporary world. As the cyber environment has expanded and become more complex, so have the nature of adversaries and styles of attacks. Today, cyber incidents are an expected part of life. As a result, cybersecurity research emerged to address adversarial attacks interfering with or preventing normal cyber activities. Historical response to cybersecurity attacks is heavily skewed to tactical responses with an emphasis on rapid recovery. While threat mitigation is important and can be time critical, a knowledge gap exists with respect to developing the sciencemore » of cybersecurity. Such a science will enable the development and testing of theories that lead to understanding the broad sweep of cyber threats and the ability to assess trade-offs in sustaining network missions while mitigating attacks. The Asymmetric Resilient Cybersecurity Initiative at Pacific Northwest National Laboratory is a multi-year, multi-million dollar investment to develop approaches for shifting the advantage to the defender and sustaining the operability of systems under attack. The initiative established a Science Council to focus attention on the research process for cybersecurity. The Council shares science practices, critiques research plans, and aids in documenting and reporting reproducible research results. The Council members represent ecology, economics, statistics, physics, computational chemistry, microbiology and genetics, and geochemistry. This paper reports the initial work of the Science Council to implement the scientific method in cybersecurity research. The second section describes the scientific method. The third section in this paper discusses scientific practices for cybersecurity research. Section four describes initial impacts of applying the science practices to cybersecurity research.« less

The Living With a Star (LWS) program addresses acute societal needs for understanding the effects of space weather and developing scientific knowledge to support predictive capabilities. Our society's heavy reliance on technologies affected by the space environment, an enormous number of airline customers, interest in space tourism, and the developing plans for long-duration human exploration space missions are clear examples that demonstrate urgent needs for space weather models and detailed understanding of space weather effects and risks. Since its inception, the LWS program has provided a vehicle to innovate new mechanisms for conducting research, building highly effective interdisciplinary teams, and ultimately in developing the scientific understanding needed to transition research tools into operational models that support the predictive needs of our increasingly space-reliant society. The advances needed require broad-based observations that cannot be obtained by large missions alone. The Decadal Survey (HDS, 2012) outlines the nation's needs for scientific development that will build the foundation for tomorrow's space weather services. Addressing these goals, LWS must develop flexible pathways to space utilizing smaller, more diverse and rapid development of observational platforms. Expanding utilization of ground-based assets and shared launches will also significantly enhance opportunities to fulfill the growing LWS data needs. Partnerships between NASA divisions, national/international agencies, and with industry will be essential for leveraging resources to address increasing societal demand for space weather advances. Strengthened connections to user communities will enhance the quality and impact of deliverables from LWS programs. Thus, we outline the developing vision for the future of LWS, stressing the need for deeper scientific understanding to improve forecasting capabilities, for more diverse data resources, and for project deliverables that address the growing needs of user communities.

Contributing to COSPAR - Contibuting to Expanding the Knowledge Frontier of Space for the Benefit of Humankind

COSPAR's objectives are to promote -on an international level- scientific research in space, with emphasis on the exchange of results, information and opinions, and to provide a forum, open to all scientists, for the discussion of problems that may affect scientific space research (https://cosparhq.cnes.fr/about/origin-purpose-role). COSPAR played an extraordinary significant role in the past by facilitating the scientific exchange between East and West … and surely contributed to the present fluid and free-flowding situation. COSPAR’s challenge now is to get a similar result by providing opportunities to less developed countries to upgrade their resources to progress on all kinds of research using space means. This presentation shows the activity developed by the Climatology from Satellites Group of the University of Valencia, Spain, during the last 10 years, in different action areas of COSPAR, and in the framework of Commission A on Space Studies of the Earth's Surface, Meteorology and Climate, especially in Sub-Commission A3 on Land Processes and Morphology, as well as in the organisation of some Capacity Building Courses akin to Commission A’s terms of reference. The effort -if any- has always and so far been worthwhile. The Group has learnt a lot, it has notably incresed its capacity for networking, as well as its opportunities to accompany scientists from less developed countries in their scientific growing and development of resources (Give a man a fish and you feed him for a day. Teach a man to fish and you feed him for a lifetime -Chinese proverb … and root and foundation for Capacity Building).

The Brazilian Science Data Center (BSDC)

Astrophysics and Space Science are becoming increasingly characterised by what is now known as “big data”, the bottlenecks for progress partly shifting from data acquisition to “data mining”. Truth is that the amount and rate of data accumulation in many fields already surpasses the local capabilities for its processing and exploitation, and the efficient conversion of scientific data into knowledge is everywhere a challenge. The result is that, to a large extent, isolated data archives risk being progressively likened to “data graveyards”, where the information stored is not reused for scientific work. Responsible and efficient use of these large data-sets means democratising access and extracting the most science possible from it, which in turn signifies improving data accessibility and integration. Improving data processing capabilities is another important issue specific to researchers and computer scientists of each field. The project presented here wishes to exploit the enormous potential opened up by information technology at our age to advance a model for a science data center in astronomy which aims to expand data accessibility and integration to the largest possible extent and with the greatest efficiency for scientific and educational use. Greater access to data means more people producing and benefiting from information, whereas larger integration of related data from different origins means a greater research potential and increased scientific impact. The project of the BSDC is preoccupied, primarily, with providing tools and solutions for the Brazilian astronomical community. It nevertheless capitalizes on extensive international experience, and is developed in full cooperation with the ASI Science Data Center (ASDC), from the Italian Space Agency, granting it an essential ingredient of internationalisation. The BSDC is Virtual Observatory-complient and part of the “Open Universe”, a global initiative built under the auspices of the United Nations.

CONTEXT: Scientific research not only promotes health and combats diseases of an individual, but also it can strengthen the effectiveness of health systems. Hence, understanding of scientific methods becomes a crucial component in the medical profession. AIMS: This study was conducted to assess the knowledge, attitudes, and barriers toward research among undergraduate medical and dental students. SETTINGS AND DESIGN: This cross-sectional study was conducted among 295 undergraduate Bachelor of Medicine and Bachelor of Surgery (MBBS) and Bachelor of Dental Surgery (BDS) students from a private medical college in Malaysia. MATERIALS AND METHODS: We purposively selected 360 students attending the 3rd, 4th, and 5th year in MBBS course and BDS course in September 2015. A total of 295 students who were willing to provide written informed consent were included in this study. We collected data using a validated, self-administered, structured questionnaire which included 20 questions about knowledge toward scientific research, 21 attitude items in regard to scientific research, a list of 10 barriers toward conducting medical research, and 5 questions of confidence to conduct the medical research. STATISTICAL ANALYSIS USED: Data were analyzed using descriptive statistics, independent t-test, ANOVA, and multiple linear regression. RESULTS: Among the students, 56.9% had moderate knowledge while the majority (83.3%) had moderate attitude toward scientific research. The majorly cited barriers were the lack of time (79.9%), lack of knowledge and skills (72.1%), lack of funding (72.0%) and facilities (63.6%), and lack of rewards (55.8%). There was a significant association between age, academic year, and knowledge of research as the older age group, and 4th- and 5th-year students had higher knowledge score. The students of higher attitude score had better-perceived barriers score toward research with regression coefficient 0.095 (95% confidence interval 0.032–0.159). CONCLUSIONS: Even though the students had the positive attitudes toward scientific research, a supportive and positive environment is needed to improve skills and knowledge of research and to overcome the barriers toward the conduct of scientific research.

On the Epistemological Crisis in Genomics

PubMed Central

Dougherty, Edward R

2008-01-01

There is an epistemological crisis in genomics. At issue is what constitutes scientific knowledge in genomic science, or systems biology in general. Does this crisis require a new perspective on knowledge heretofore absent from science or is it merely a matter of interpreting new scientific developments in an existing epistemological framework? This paper discusses the manner in which the experimental method, as developed and understood over recent centuries, leads naturally to a scientific epistemology grounded in an experimental-mathematical duality. It places genomics into this epistemological framework and examines the current situation in genomics. Meaning and the constitution of scientific knowledge are key concerns for genomics, and the nature of the epistemological crisis in genomics depends on how these are understood. PMID:19440447

Is risk analysis scientific?

PubMed

Hansson, Sven Ove; Aven, Terje

2014-07-01

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.

The dual-use problem, scientific isolationism and the division of moral labour.

PubMed

Douglas, Thomas

2014-01-01

The dual-use problem is an ethical quandary sometimes faced by scientists and others in a position to influence the creation or dissemination of scientific knowledge. It arises when (i) an agent is considering whether to pursue some project likely to result in the creation or dissemination of scientific knowledge, (ii) that knowledge could be used in both morally desirable and morally undesirable ways, and (iii) the risk of undesirable use is sufficiently high that it is not clear that the agent may permissibly pursue the project or policy. Agents said to be faced with dual-use problems have frequently responded by appealing to a view that I call scientific isolationism. This is, roughly, the view that scientific decisions may be made without morally appraising the likely uses of the scientific knowledge whose production or dissemination is at stake. I consider whether scientific isolationism can be justified in a form that would indeed provide a way out of dual-use problems. I first argue for a presumption against a strong form of isolationism, and then examine four arguments that might be thought to override this presumption. The most promising of these arguments appeals to the idea of a division of moral labour, but I argue that even this argument can sustain at most a highly attenuated form of scientific isolationism and that this variant of isolationism has little practical import for discussions of the dual-use problem.

Examining elementary teachers' knowledge and instruction of scientific explanations for fostering children's explanations in science

NASA Astrophysics Data System (ADS)

Wiebke, Heidi Lynn

This study employed an embedded mixed methods multi-case study design (Creswell, 2014) with six early childhood (grades K-2) teachers to examine a) what changes occurred to their subject matter knowledge (SMK) and pedagogical content knowledge (PCK) for teaching scientific explanations while participating in a professional development program, b) how they planned for and implemented scientific explanation instruction within a teacher developed unit on properties of matter, and c) what affordances their instruction of scientific explanations had on fostering their students' abilities to generate explanations in science. Several quantitative and qualitative measures were collected and analyzed in accordance to this studies conceptual framework, which consisted of ten instructional practices teachers should consider assimilating or accommodating into their knowledge base (i.e., SMK & PCK) for teaching scientific explanations. Results of this study indicate there was little to no positive change in the teachers' substantive and syntactic SMK. However, all six teachers did make significant changes to all five components of their PCK for teaching explanations in science. While planning for scientific explanation instruction, all six teachers' contributed some ideas for how to incorporate seven of the ten instructional practices for scientific explanations within the properties of matter unit they co-developed. When enacting the unit, the six teachers' employed seven to nine of the instructional practices to varying levels of effectiveness, as measured by researcher developed rubrics. Given the six teachers' scientific explanation instruction, many students did show improvement in their ability to formulate a scientific explanation, particularly their ability to provide multiple pieces of evidence. Implications for professional developers, teacher educators, researchers, policy makers, and elementary teachers regarding how to prepare teachers for and support students' construction of scientific explanations are discussed.

Scientific and Cultural Knowledge in Intercultural Science Education: Student Perceptions of Common Ground

Gondwe, Mzamose; Longnecker, Nancy

2015-02-01

There is no consensus in the science education research community on the meanings and representations of western science and indigenous knowledge or the relationships between them. How students interpret these relationships and their perceptions of any connections has rarely been studied. This study reports student perceptions of the meaning and relationship between scientific and cultural knowledge. Personal meaning maps adapted for small groups were conducted in seven culturally diverse schools, school years 7-9 (with students aged 12-15 years) ( n = 190), with six schools in Western Australia and one school in Malawi, Africa. Of the six Australian school groups, two comprised Australian Aboriginal students in an after-school homework programme and the other four schools had a multicultural mix of students. Students in this study identified connections between scientific and cultural knowledge and constructed connections from particular thematic areas—mainly factual content knowledge as opposed to ideas related to values, attitudes, beliefs and identity. Australian Aboriginal students made fewer connections between the two knowledge domains than Malawian students whose previous science teacher had made explicit connections in her science class. Examples from Aboriginal culture were the most dominant illustrations of cultural knowledge in Australian schools, even in school groups with students from other cultures. In light of our findings, we discuss the construction of common ground between scientific knowledge and cultural knowledge and the role of teachers as cultural brokers and travel agents. We conclude with recommendations on creating learning environments that embrace different cultural knowledges and that promote explicit and enquiring discussions of values, attitudes, beliefs and identity associated with both knowledge domains.

Public Attitudes Toward Expanded Newborn Screening.

PubMed

DeLuca, Jane M

There is limited research available on public knowledge and understanding of expanded newborn screening (NBS). The aims of this study were to assess current public knowledge and understanding of newborn screening disorders and procedures, perceived education needs, and preferences for the delivery of NBS information and education. An additional aim was to develop a beginning understanding of public attitudes toward screening for complex, severe, and in some cases untreatable disorders. In this preliminary descriptive study, eighty-eight participants completed surveys querying their general knowledge of NBS, preferred means of receiving NBS information and education, and their opinions about screening for severe disorders such as lysosomal storage diseases (LSD). Most study participants lacked general knowledge about current NBS practices, however, they supported expanding screening for severe and in some cases untreatable conditions. Most participants were enthusiastic about expanding NBS; however, those with more years of education were cautious regarding extensive costs of diagnosing and treating rare disorders. Newborn screening continues to evolve through new technological developments and the addition of more disorders to screening panels. More research of into public acceptance of newborn screening is needed. Addressing the educational needs of the public is important for improving their understanding of NBS and promoting patient-centered care in the era of genomic screening. Enhanced educational efforts are necessary for improving public understanding of newborn screening. Copyright © 2017 Elsevier Inc. All rights reserved.

Throughout the world, biomedical knowledge is routinely generated and shared through primary and secondary scientific publications. However, there is too much latency between publication of knowledge and its routine use in practice. To address this latency, what is actionable in scientific publications can be encoded to make it computable. We have created a purpose-built digital library platform to hold, manage, and share actionable, computable knowledge for health called the Knowledge Grid Library. Here we present it with its system architecture.

Scaffolding Middle School Students' Construction of Scientific Explanations: Comparing a cognitive versus a metacognitive evaluation approach

NASA Astrophysics Data System (ADS)

Wang, Chia-Yu

2015-01-01

This study investigated the effects of scaffolds as cognitive prompts and as metacognitive evaluation on seventh-grade students' growth of content knowledge and construction of scientific explanations in five inquiry-based biology activities. Students' scores on multiple-choice pretest and posttest and worksheets for five inquiry-based activities were analyzed. The results show that the students' content knowledge in all conditions significantly increased from the pretest to posttest. Incorporating cognitive prompts with the explanation scaffolds better facilitated knowledge integration and resulted in greater learning gains of content knowledge and better quality evidence and reasoning. The metacognitive evaluation instruction improved all explanation components, especially claims and reasoning. This metacognitive approach also significantly reduced students' over- or underestimation during peer-evaluation by refining their internal standards for the quality of scientific explanations. The ability to accurately evaluate the quality of explanations was strongly associated with better performance on explanation construction. The cognitive prompts and metacognitive evaluation instruction address different aspects of the challenges faced by the students, and show different effects on the enhancement of content knowledge and the quality of scientific explanations. Future directions and suggestions are provided for improving the design of the scaffolds to facilitate the construction of scientific explanations.

Undergraduate honors students' images of science: Nature of scientific work and scientific knowledge

NASA Astrophysics Data System (ADS)

Wallace, Michael L.

This exploratory study assessed the influence of an implicit, inquiry-oriented nature of science (NOS) instructional approach undertaken in an interdisciplinary college science course on undergraduate honor students' (UHS) understanding of the aspects of NOS for scientific work and scientific knowledge. In this study, the nature of scientific work concentrated upon the delineation of science from pseudoscience and the value scientists place on reproducibility. The nature of scientific knowledge concentrated upon how UHS view scientific theories and how they believe scientists utilize scientific theories in their research. The 39 UHS who participated in the study were non-science majors enrolled in a Honors College sponsored interdisciplinary science course where the instructors took an implicit NOS instructional approach. An open-ended assessment instrument, the UFO Scenario, was designed for the course and used to assess UHS' images of science at the beginning and end of the semester. The mixed-design study employed both qualitative and quantitative techniques to analyze the open-ended responses. The qualitative techniques of open and axial coding were utilized to find recurring themes within UHS' responses. McNemar's chi-square test for two dependent samples was used to identify whether any statistically significant changes occurred within responses from the beginning to the end of the semester. At the start of the study, the majority of UHS held mixed NOS views, but were able to accurately define what a scientific theory is and explicate how scientists utilize theories within scientific research. Postinstruction assessment indicated that UHS did not make significant gains in their understanding of the nature of scientific work or scientific knowledge and their overall images of science remained static. The results of the present study found implicit NOS instruction even with an extensive inquiry-oriented component was an ineffective approach for modifying UHS' images of science towards a more informed view of NOS.

Enhancing endorsement of scientific inquiry increases support for pro-environment policies.

Pro-environment policies require public support and engagement, but in countries such as the USA, public support for pro-environment policies remains low. Increasing public scientific literacy is unlikely to solve this, because increased scientific literacy does not guarantee increased acceptance of critical environmental issues (e.g. that climate change is occurring). We distinguish between scientific literacy (basic scientific knowledge) and endorsement of scientific inquiry (perceiving science as a valuable way of accumulating knowledge), and examine the relationship between people's endorsement of scientific inquiry and their support for pro-environment policy. Analysis of a large, publicly available dataset shows that support for pro-environment policies is more strongly related to endorsement of scientific inquiry than to scientific literacy among adolescents. An experiment demonstrates that a brief intervention can increase support for pro-environment policies via increased endorsement of scientific inquiry among adults. Public education about the merits of scientific inquiry may facilitate increased support for pro-environment policies.

Adjudicating non-knowledge in the Omnibus Autism Proceedings.

PubMed

Decoteau, Claire Laurier; Underman, Kelly

2015-08-01

After 5600 families of children diagnosed with autism filed claims with the National Vaccine Injury Compensation Program in the United States, the court selected 'test' cases consolidated into the Omnibus Autism Proceedings, held from 2007 to 2008, to examine claims that vaccines caused the development of autism. The court found all of the causation theories presented to be untenable and did not award damages to any parents. We analyze the Omnibus Autism Proceedings as a struggle within the scientific field between the scientific orthodoxy of the respondents and the heterodox position taken by the plaintiffs, suggesting that the ruling in these cases helped to shore up hegemony on autism causation. Drawing on the literature on non-knowledge, we suggest that only the respondents had enough scientific capital to strategically direct non-knowledge toward genetic research, thereby foreclosing the possibility of environmental causation of autism. The plaintiffs, who promote a non-standard ontology of autism, suggest that the science on autism remains undone and should not be circumscribed. In analyzing the Omnibus Autism Proceedings with field theory, we highlight the way in which scientific consensus-building and the setting of research agendas are the result of struggle, and we show that the strategic deployment of non-knowledge becomes a major stake in battles for scientific legitimacy and the settling of scientific controversies.

A general overview of the history of soil science

NASA Astrophysics Data System (ADS)

Brevik, Eric C.; Cerdà, Artemi

2017-04-01

Human knowledge of soil has come a long way since agriculture began about 9000 BCE, when finding the best soils to grow crops in was largely based on a trial and error approach. Many innovations to manage and conserve soil, such as the plow, irrigation techniques, terraces, contour tillage, and even the engineering of artificial soils, were developed between 9000 BCE and 1500 CE. Scientific methods began to be employed in the study of soils during the Renaissance and many famous scientists addressed soil issues, but soil science did not evolve into an independent scientific field of study until the 1880s. In the early days of the study of soil as a science, soil survey activities provided one of the major means of advancing the field. As the 20th century progressed, advances in soil biology, chemistry, genesis, management, and physics allowed the use of soil information to expand beyond agriculture to environmental issues, human health, land use planning, and many other areas. The development of soil history as a subfield of the discipline in the latter part of the 20th century has promise to help advance soil science through a better understanding of how we have arrived at the major theories that shape the modern study of soil science.

A socio-scientific analysis of the environmental and health benefits as well as potential risks of cassava production and consumption.

Mombo, S; Dumat, C; Shahid, M; Schreck, E

Due to its high adaptability, cassava (Manihot esculenta Crantz) is one of the world's most cultivated and consumed plants after maize and rice. However, there are relatively few scientific studies on this important crop. The objective of this review was therefore to summarize and discuss the available information on cassava cropping in order to promote sustainable practices in terms of production and consumption. Cassava cultivation has been expanding recently at the global scale and is widely consumed in most regions of South America, Africa, and Asia. However, it is also characterized by the presence in its roots of potentially toxic hydrocyanic acid. Furthermore, cassava can also absorb pollutants as it is currently cultivated near roads or factories and generally without consideration for potential sources of soil, water, or atmospheric pollution. Careful washing, peeling, and adequate preparation before eating are therefore crucial steps for reducing human exposure to both environmental pollutants and natural hydrocyanic acid. At present, there is not enough precise data available on this staple food crop. To improve our knowledge on the nutritive benefits versus health risks associated with cassava consumption, further research is necessary to compare cassava cultivars and precisely study the influence of preparation methods.

This article shows the results of a qualitative evaluation on the expansion of the Collective Health area according with the production of the triennial Collective Health Congresses Annals which happen between 1997 to 2006, promoted by Abrasco - Brazilian Association of Collective Health. The specific objective was to estimate the growth of importance of the area in the scientific as well as in the social Brazilian scenario in the last decennary through the analysis of aspects and substantive dimensions. The methodological strategy of the study was to consider the complexity and data profusion referred to the dimensions of this multidisciplinary field (more and more interdisciplinary) of knowledge and intervention. From this perspective, analysis and interpretations of document sources were done, applying theoretical, methodological and analytical referential of the social science and X statistics techniques. It could be observed that: (1) in the last decade, the Collective Health area expanded into its three subareas (Epidemiology, Planning/Management and Health Services and, Human Sciences); (2) there is a tendency of more interactivity among the programs and with their communities and the institutions; (3) there is a growth in the quantity of authors writing about the field and different authors by article; (4) it is being elaborated a big internal specialization into the subareas.

Varieties of (Scientific) Creativity: A Hierarchical Model of Domain-Specific Disposition, Development, and Achievement.

PubMed

Simonton, Dean Keith

2009-09-01

Prior research supports the inference that scientific disciplines can be ordered into a hierarchy ranging from the "hard" natural sciences to the "soft" social sciences. This ordering corresponds with such objective criteria as disciplinary consensus, knowledge obsolescence rate, anticipation frequency, theories-to-laws ratio, lecture disfluency, and age at recognition. It is then argued that this hierarchy can be extrapolated to encompass the humanities and arts and interpolated within specific domains to accommodate contrasts in subdomains (e.g., revolutionary versus normal science). This expanded and more finely differentiated hierarchy is then shown to have a partial psychological basis in terms of dispositional traits (e.g., psychopathology) and developmental experiences (e.g., family background). This demonstration then leads to three hypotheses about how a creator's domain-specific impact depends on his or her disposition and development: the domain-progressive, domain-typical, and domain-regressive creator hypotheses. Studies published thus far lend the most support to the domain-regressive creator hypothesis. In particular, major contributors to a domain are more likely to have dispositional traits and developmental experiences most similar to those that prevail in a domain lower in the disciplinary hierarchy. However, some complications to this generalization suggest the need for more research on the proposed hierarchical model. © 2009 Association for Psychological Science.

Comet Plunge and CME on the Sun

NASA Image and Video Library

2017-12-08

A small comet was streaking towards the Sun when the Sun blew out a "halo" coronal mass ejection (CME) Aug. 19-20, 2013). The CME originated from the far side of the Sun and did not have any interaction with the comet. The comet, only perhaps 30 meters across, was not seen after it went out of view, likely disintegrated by the heat and radiation from the Sun. We call this a "full halo" CME since the front edge of the CME is expanding in all directions around the Sun like a halo. The images were taken by SOHO's coronagraphs in which a disk (red) blocks the Sun and some of the area around it so we can see faint structures beyond that. Here we superimposed the Sun from NASA's SDO. The movie covers about five hours of activity and can be seen here: www.flickr.com/photos/gsfc/9601034896/ Credit: NASA/Goddard/SOHO NASA image use policy.

Cannabis Smoking in 2015: A Concern for Lung Health?

PubMed

Biehl, Jason R; Burnham, Ellen L

2015-09-01

Recent legislative successes allowing expanded access to recreational and medicinal cannabis have been associated with its increased use by the public, despite continued debates regarding its safety within the medical and scientific communities. Despite legislative changes, cannabis is most commonly used by smoking, although alternatives to inhalation have also emerged. Moreover, the composition of commercially available cannabis has dramatically changed in recent years. Therefore, developing sound scientific information regarding its impact on lung health is imperative, particularly because published data conducted prior to widespread legalization are conflicting and inconclusive. In this commentary, we delineate major observations of epidemiologic investigations examining cannabis use and the potential associated development of airways disease and lung cancer to highlight gaps in pulmonary knowledge. Additionally, we review major histopathologic alterations related to smoked cannabis and define specific areas in animal models and human clinical translational investigations that could benefit from additional development. Given that cannabis has an ongoing classification as a schedule I medication, federal funding to support investigations of modern cannabis use in terms of medicinal efficacy and safety profile on lung health have been elusive. It is clear, however, that the effects of inhaled cannabis on lung health remain uncertain and given increasing use patterns, are worthy of further investigation.

Over the last years, public outreach has become an integral part of scientific work. In order to motivate the next generation of scientist and in cooperation with the JuniorUniversity program of the University of Cologne and the Cologne Science Adventure "Odysseum" we at the I. Physikalisches Institut developed a concept to introduce our up-to-date scientific work to teenagers between 13 and 15 years of age. The main idea was to motivate adolescents, to provide a cheerful contact with science and the local university, and to have fun. The focus of our scientific work are wind measurements in the upper atmospheres of Mars and Venus by high resolution infrared spectroscopy. The main concept of these observations is quite simple, just involving spectroscopic measurements of light and the well-known Doppler effect. This observational concept as well as general information on the planets were transported during one day consisting of various events. The morning was organized by the Odysseum. Two instructional workshops ("Venus, Earth, Mars", "Mission to Mars") with high "fun-factor" were offered providing an appropriate environment for the children and easy access to the subject. Basic information about the planets Mars and Venus was conveyed as well as some aspects on possible space missions to these planets. Based on that information the children visited our institute in the afternoon where two workshops with hands-on experiments provided deeper inside to the technique of spectroscopy ("Information from the Universe") and the problems of conducting astronomical observations ("Hitch-hiking through the universe"). The latter was also used to introduce the basic methods of how to write a scientific proposal for telescope observing time. Finally, to round up the day and to increase our targeted audience, parents and friends where invited to attend a presentation of the results of the day given by the participants as well as a brief introduction into our scientific work on investigations of dynamical properties on Mars and Venus expanding the knowledge gathered during the day.

Promoting Art through Technology, Education and Research of Natural Sciences (PATTERNS) across Wyoming, A Wyoming NSF EPSCoR Funded Project

NASA Astrophysics Data System (ADS)

Gellis, B. S.; McElroy, B. J.

2016-12-01

PATTERNS across Wyoming is a science and art project that promotes new and innovative approaches to STEM education and outreach, helping to re-contextualize how educators think about creative knowledge, and how to reach diverse audiences through informal education. The convergence of art, science and STEM outreach efforts is vital to increasing the presence of art in geosciences, developing multidisciplinary student research opportunities, expanding creative STEM thinking, and generating creative approaches of visualizing scientific data. A major goal of this project is to train art students to think critically about the value of scientific and artistic inquiry. PATTERNS across Wyoming makes science tangible to Wyoming citizens through K-14 art classrooms, and promotes novel maker-based art explorations centered around Wyoming's geosciences. The first PATTERNS across Wyoming scientific learning module (SIM) is a fish-tank sized flume that recreates natural patterns in sand as a result of fluid flow and sediment transport. It will help promotes the understanding of river systems found across Wyoming (e.g. Green, Yellowstone, Snake). This SIM, and the student artwork inspired by it, will help to visualize environmental-water changes in the central Rocky Mountains and will provide the essential inspiration and tools for Wyoming art students to design biological-driven creative explorations. Each art class will receive different fluvial system conditions, allowing for greater understanding of river system interactions. Artwork will return to the University of Wyoming for a STE{A}M Exhibition inspired by Wyoming's varying fluvial systems. It is our hope that new generations of science and art critical thinkers will not only explore questions of `why' and `how' scientific phenomena occur, but also `how' to better predict, conserve and study invaluable artifacts, and visualize conditions which allow for better control of scientific outcomes and public understanding.

The Orbital Space Environment and Space Situational Awareness Domain Ontology - Toward an International Information System for Space Data

NASA Astrophysics Data System (ADS)

Rovetto, R.

2016-09-01

The orbital space environment is home to natural and artificial satellites, debris, and space weather phenomena. As the population of orbital objects grows so do the potential hazards to astronauts, space infrastructure and spaceflight capability. Orbital debris, in particular, is a universal concern. This and other hazards can be minimized by improving global space situational awareness (SSA). By sharing more data and increasing observational coverage of the space environment we stand to achieve that goal, thereby making spaceflight safer and expanding our knowledge of near-Earth space. To facilitate data-sharing interoperability among distinct orbital debris and space object catalogs, and SSA information systems, I proposed ontology in (Rovetto, 2015) and (Rovetto and Kelso, 2016). I continue this effort toward formal representations and models of the overall domain that may serve to improve peaceful SSA and increase our scientific knowledge. This paper explains the project concept introduced in those publications, summarizing efforts to date as well as the research field of ontology development and engineering. I describe concepts for an ontological framework for the orbital space environment, near-Earth space environment and SSA domain. An ontological framework is conceived as a part of a potential international information system. The purpose of such a system is to consolidate, analyze and reason over various sources and types of orbital and SSA data toward the mutually beneficial goals of safer space navigation and scientific research. Recent internationals findings on the limitations of orbital data, in addition to existing publications on collaborative SSA, demonstrate both the overlap with this project and the need for datasharing and integration.

To investigate providers' knowledge and attitudes about medical abortion (MA) and their views regarding the main challenges to expanding the use of MA in urban and rural areas in China. A total of 658 abortion providers were surveyed from November 7, 2009, to May 29, 2010. The providers' knowledge about MA was relatively poor, and most thought the risks of severe complications of MA were much higher than they are. Urban nonphysician providers were the least informed about MA. Most providers thought that the main challenges to an expanded use of MA were its lesser effectiveness in comparison to surgical abortion and women's lack of knowledge about it. In rural areas many providers thought that deficiencies of clinics, such as limited bed space and inadequate toilets and washing facilities, also posed serious obstacles to expanding MA use. Abortion providers, especially urban nonphysician providers, need refresher training to strengthen their knowledge of the approved protocol for providing MA in China, and also of the indications, contraindications, and safety and efficacy of the method. Deficiencies at abortion facilities should be addressed as well, and they are more numerous in rural areas. Copyright © 2012 International Federation of Gynecology and Obstetrics.

Measuring science or religion? A measurement analysis of the National Science Foundation sponsored science literacy scale 2006-2010.

PubMed

Roos, J Micah

2014-10-01

High scientific literacy is widely considered a public good. Methods of assessing public scientific knowledge or literacy are equally important. In an effort to measure lay scientific literacy in the United States, the National Science Foundation (NSF) science literacy scale has been a part of the last three waves of the General Social Survey. However, there has been debate over the validity of some survey items as indicators of science knowledge. While many researchers treat the NSF science scale as measuring a single dimension, previous work (Bann and Schwerin, 2004; Miller, 1998, 2004) suggests a bidimensional structure. This paper hypothesizes and tests a new measurement model for the NSF science knowledge scale and finds that two items about evolution and the big bang are more measures of a religious belief dimension termed "Young Earth Worldview" than they are measures of scientific knowledge. Results are replicated in seven samples. © The Author(s) 2013.

Knowledge first, critique later: why it is a mistake for science education to encourage junior students to discuss, challenge and debate scientific knowledge.

PubMed

Charlton, Bruce G

2010-02-01

In UK educational circles it has long been regarded as a platitude that a good scientific education at school and undergraduate level should aim to teach critical thinking and encourage students to challenge mainstream science, debate scientific issues and express their personal opinions. However, I believe that this strategy is usually mistaken, and that such educational strategies probably do more harm than good. For most students, at most levels, for most of the time; science education should be focused on the inculcation of established knowledge. This is for the simple reason that critique is educationally-counterproductive and scientifically-worthless unless or until underpinned by adequate knowledge and competence. Instead, for the early years of science teaching, the basic assumption ought to be that the student is there to learn science; not to confront science. The basic attitude being taught should be one of humility before the science being studied.

Contemporary HIV/AIDS research: Insights from knowledge management theory

PubMed Central

Callaghan, Chris William

2017-01-01

Abstract Knowledge management as a field is concerned with the management of knowledge, including the management of knowledge in research processes. Knowledge management theory has the potential to support research into problems such as HIV, antibiotic resistance and others, particularly in terms of aspects of scientific research related to the contribution of social science. To date, however, these challenges remain with us, and theoretical contributions that can complement natural science efforts to eradicate these problems are needed. This paper seeks to offer a theoretical contribution grounded in Kuhn’s paradigm theory of innovation, and in the argument by Lakatos that scientific research can be fundamentally non-innovative, which suggests that social science aspects of knowledge creation may hold the key to more effective biomedical innovation. Given the consequences of ongoing and emerging global crises, and the failure of knowledge systems of scientific research to solve such problems outright, this paper provides a review of theory and literature arguing for a new paradigm in scientific research, based on the development of global systems to maximise research collaborations. A global systems approach effectively includes social science theory development as an important complement to the natural sciences research process. Arguably, information technology and social media technology have developed to the point at which solutions to knowledge aggregation challenges can enable solutions to knowledge problems on a scale hitherto unimaginable. Expert and non-expert crowdsourced inputs can enable problem-solving through exponentially increasing problem-solving inputs, using the ‘crowd,’ thereby increasing collaborations dramatically. It is argued that these developments herald a new era of participatory research, or a democratisation of research, which offers new hope for solving global social problems. This paper seeks to contribute to this end, and to the recognition of the important role of social theory in the scientific research process. PMID:28922967

Achieving land degradation neutrality (LDN) through sustainable land management (SLM) targets the maintenance or restoration of the productivity of land, and therefore has to include decision-makers, knowledge generators and knowledge holders at the different relevant geographic scales. In order to enhance the implementation of the Convention, the Conference of the Parties (COP) of the United Nations Convention to Combat Desertification therefore decided that each future session of its Committee on Science and Technology (CST) would be organized in a predominantly scientific and technical conference-style format. This contribution will outline the major outcomes of UNCCD's 3rd scientific conference that will be held in Cancún, Mexico, from 9 to 12 March 2015, on addressing desertification, land degradation and drought issues (DLDD) for poverty reduction and sustainable development. The conference follows an exceptional new round table conference format that will allow the various stakeholders to discuss scientific as well as the contribution of traditional knowledge and practices in combating land degradation. This format should provide two-way communication and enable deeper insight into the availability and contribution of all forms of knowledge for achieving LDN through the assessment of: • the vulnerability of lands to DLDD and climate change and the adaptive capacities of socio-ecosystems; • best examples of adapted, knowledge-based practices and technologies; • monitoring and assessment methods to evaluate the effectiveness of adaptation practices and technologies. The outcomes of UNCCD's 3rd scientific conference will serve as a basis for discussing: • contributions of science to diagnose the status of land; • research gaps that need to be addressed to achieve LDN for poverty reduction; • additional institutional requirements to optimally bridge knowledge generation, knowledge maintenance and knowledge implementation at the science-policy interface.

Scientific Visualization and Computational Science: Natural Partners

NASA Technical Reports Server (NTRS)

Uselton, Samuel P.; Lasinski, T. A. (Technical Monitor)

1995-01-01

Scientific visualization is developing rapidly, stimulated by computational science, which is gaining acceptance as a third alternative to theory and experiment. Computational science is based on numerical simulations of mathematical models derived from theory. But each individual simulation is like a hypothetical experiment; initial conditions are specified, and the result is a record of the observed conditions. Experiments can be simulated for situations that can not really be created or controlled. Results impossible to measure can be computed.. Even for observable values, computed samples are typically much denser. Numerical simulations also extend scientific exploration where the mathematics is analytically intractable. Numerical simulations are used to study phenomena from subatomic to intergalactic scales and from abstract mathematical structures to pragmatic engineering of everyday objects. But computational science methods would be almost useless without visualization. The obvious reason is that the huge amounts of data produced require the high bandwidth of the human visual system, and interactivity adds to the power. Visualization systems also provide a single context for all the activities involved from debugging the simulations, to exploring the data, to communicating the results. Most of the presentations today have their roots in image processing, where the fundamental task is: Given an image, extract information about the scene. Visualization has developed from computer graphics, and the inverse task: Given a scene description, make an image. Visualization extends the graphics paradigm by expanding the possible input. The goal is still to produce images; the difficulty is that the input is not a scene description displayable by standard graphics methods. Visualization techniques must either transform the data into a scene description or extend graphics techniques to display this odd input. Computational science is a fertile field for visualization research because the results vary so widely and include things that have no known appearance. The amount of data creates additional challenges for both hardware and software systems. Evaluations of visualization should ultimately reflect the insight gained into the scientific phenomena. So making good visualizations requires consideration of characteristics of the user and the purpose of the visualization. Knowledge about human perception and graphic design is also relevant. It is this breadth of knowledge that stimulates proposals for multidisciplinary visualization teams and intelligent visualization assistant software. Visualization is an immature field, but computational science is stimulating research on a broad front.

Crossing Science-Policy-Societal Boundaries to Reduce Scientific and Institutional Uncertainty in Small-Scale Fisheries.

Sutton, Abigail M; Rudd, Murray A

2016-10-01

The governance of small-scale fisheries (SSF) is challenging due to the uncertainty, complexity, and interconnectedness of social, political, ecological, and economical processes. Conventional SSF management has focused on a centralized and top-down approach. A major criticism of conventional management is the over-reliance on 'expert science' to guide decision-making and poor consideration of fishers' contextually rich knowledge. That is thought to exacerbate the already low governance potential of SSF. Integrating scientific knowledge with fishers' knowledge is increasingly popular and is often assumed to help reduce levels of biophysical and institutional uncertainties. Many projects aimed at encouraging knowledge integration have, however, been unsuccessful. Our objective in this research was to assess factors that influence knowledge integration and the uptake of integrated knowledge into policy-making. We report results from 54 semi-structured interviews with SSF researchers and practitioners from around the globe. Our analysis is framed in terms of scientific credibility, societal legitimacy, and policy saliency, and we discuss cases that have been partially or fully successful in reducing uncertainty via push-and-pull-oriented boundary crossing initiatives. Our findings suggest that two important factors affect the science-policy-societal boundary: a lack of consensus among stakeholders about what constitutes credible knowledge and institutional uncertainty resulting from shifting policies and leadership change. A lack of training for scientific leaders and an apparent 'shelf-life' for community organizations highlight the importance of ongoing institutional support for knowledge integration projects. Institutional support may be enhanced through such investments, such as capacity building and specialized platforms for knowledge integration.

2017-04-01

The present study was aimed at investigating the effects of a video feedback coaching intervention for upper-grade primary school teachers on students' cognitive gains in scientific knowledge. This teaching intervention was designed with the use of inquiry-based learning principles for teachers, such as the empirical cycle and the posing of thought-provoking questions. The intervention was put into practice in 10 upper-grade classrooms. The trajectory comprised four lessons, complemented with two premeasures and two postmeasures. The control condition consisted of 11 upper-grade teachers and their students. The success of the intervention was tested using an established standardized achievement test and situated measures. In this way, by means of premeasure and postmeasure questionnaires and video data, an assessment could be made of the change in students' scientific knowledge before, during, and after the intervention. In this study, we primarily focused on the dynamics of students' real-time expressions of scientific knowledge in the classroom. Important indicators of the effect of the intervention were found. Through focusing on the number of explanations and predictions, a significant increase could be seen in the proportion of students' utterances displaying scientific understanding in the intervention condition. In addition, students in the intervention condition more often reasoned on higher complexity levels than students in the control condition. No effect was found for students' scientific knowledge as measured with a standardized achievement test. Implications for future studies are stressed, as well as the importance of enriching the evaluation of intervention studies by focusing on dynamics in the classroom.

2016-04-26

It is becoming increasingly recognized that our collective ability to tackle complex problems will require the development of new, adaptive, and innovative institutional arrangements that can deal with rapidly changing knowledge and have effective learning capabilities. In this paper, we applied a knowledge-systems perspective to examine how institutional innovations can affect the generation, sharing, and application of scientific and technical knowledge. We report on a case study that examined the effects that one large innovative organization, The Global Fund to Fight AIDS, Tuberculosis, and Malaria, is having on the knowledge dimensions of decision-making in global health. The case study shows that the organization created demand for new knowledge from a range of actors, but it did not incorporate strategies for meeting this demand into their own rules, incentives, or procedures. This made it difficult for some applicants to meet the organization's dual aims of scientific soundness and national ownership of projects. It also highlighted that scientific knowledge needed to be integrated with managerial and situational knowledge for success. More generally, the study illustrates that institutional change targeting implementation can also significantly affect the dynamics of knowledge creation (learning), access, distribution, and use. Recognizing how action-oriented institutions can affect these dynamics across their knowledge system can help institutional designers build more efficient and effective institutions for sustainable development.

Towards AN Integrated Scientific and Social Case for Human Space Exploration

NASA Astrophysics Data System (ADS)

Crawford, I. A.

2004-06-01

I will argue that an ambitious programme of human space exploration, involving a return to the Moon, and eventually human missions to Mars, will add greatly to human knowledge. Gathering such knowledge is the primary aim of science, but science’s compartmentalisation into isolated academic disciplines tends to obscure the overall strength of the scientific case. Any consideration of the scientific arguments for human space exploration must therefore take a holistic view, and integrate the potential benefits over the entire spectrum of human knowledge. Moreover, science is only one thread in a much larger overall case for human space exploration. Other threads include economic, industrial, educational, geopolitical and cultural benefits. Any responsibly formulated public space policy must weigh all of these factors before deciding whether or not an investment in human space activities is scientifically and socially desirable.

Science in the everyday world: Why perspectives from the history of science matter.

PubMed

Pandora, Katherine; Rader, Karen A

2008-06-01

The history of science is more than the history of scientists. This essay argues that various modem "publics" should be counted as belonging within an enlarged vision of who constitutes the "scientific community"--and describes how the history of science could be important for understanding their experiences. It gives three examples of how natural knowledge-making happens in vernacular contexts: Victorian Britain's publishing experiments in "popular science" as effective literary strategies for communicating to lay and specialist readers; twentieth-century American science museums as important and contested sites for conveying both scientific ideas and ideas about scientific practice; and contemporary mass-mediated images of the "ideal" scientist as providing counternarratives to received professional scientific norms. Finally, it suggests how humanistic knowledge might help both scientists and historians grapple more effectively with contemporary challenges presented by science in public spheres. By studying the making and elaboration of scientific knowledge within popular culture, historians of science can provide substantively grounded insights into the relations between the public and professionals.

Numerical modelling of multi-vane expander operating conditions in ORC system

NASA Astrophysics Data System (ADS)

Rak, Józef; Błasiak, Przemysław; Kolasiński, Piotr

2017-11-01

Multi-vane expanders are positive displacement volumetric machines which are nowadays considered for application in micro-power domestic ORC systems as promising alternative to micro turbines and other volumetric expanders. The multi-vane expander features very simple design, low gas flow capacity, low expansion ratios, an advantageous ratio of the power output to the external dimensions and are insensitive to the negative influence of the gas-liquid mixture expansion. Moreover, the multi-vane expander can be easily hermetically sealed, which is one of the key issues in the ORC system design. A literature review indicates that issues concerning the application of multi-vane expanders in such systems, especially related to operating of multi-vane expander with different low-boiling working fluids, are innovative, not fully scientifically described and have the potential for practical implementation. In this paper the results of numerical investigations on multi-vane expander operating conditions are presented. The analyses were performed on three-dimensional numerical model of the expander in ANSYS CFX software. The numerical model of the expander was validated using the data obtained from the experiment carried out on a lab test-stand. Then a series of computational analysis were performed using expanders' numerical model in order to determine its operating conditions under various flow conditions of different working fluids.

The coexistence of alternative and scientific conceptions in physics

NASA Astrophysics Data System (ADS)

Ozdemir, Omer F.

The purpose of this study was to inquire about the simultaneous coexistence of alternative and scientific conceptions in the domain of physics. This study was particularly motivated by several arguments put forward in opposition to the Conceptual Change Model. In the simplest form, these arguments state that people construct different domains of knowledge and different modes of perception in different situations. Therefore, holding different conceptualizations is unavoidable and expecting a replacement in an individual's conceptual structure is not plausible in terms of instructional practices. The following research questions were generated to inquire about this argument: (1) Do individuals keep their alternative conceptions after they have acquired scientific conceptions? (2) Assuming that individuals who acquired scientific conceptions also have alternative conceptions, how are these different conceptions nested in their conceptual structure? (3) What kind of knowledge, skills, and reasoning are necessary to transfer scientific principles instead of alternative ones in the construction of a valid model? Analysis of the data collected from the non-physics group indicated that the nature of alternative conceptions is framed by two types of reasoning: reasoning by mental simulation and semiformal reasoning. Analysis of the data collected from the physics group revealed that mental images or scenes feeding reasoning by mental simulation had not disappeared after the acquisition of scientific conceptions. The analysis of data also provided enough evidence to conclude that alternative principles feeding semiformal reasoning have not necessarily disappeared after the acquisition of scientific conceptions. However, in regard to semiformal reasoning, compartmentalization was not as clear as the case demonstrated in reasoning by mental simulation; instead semiformal and scientific reasoning are intertwined in a way that the components of semiformal reasoning can easily take their place among the components of scientific reasoning. In spite of the fact that the coexistence of multiple conceptions might obstruct the transfer of scientific conceptions in problem-solving situations, several factors stimulating the use of scientific conceptions were noticed explicitly. These factors were categorized as follows: (a) the level of individuals' domain specific knowledge in the corresponding field, (b) the level of individuals' knowledge about the process of science (how science generates its knowledge claims), (c) the level of individuals' awareness of different types of reasoning and conceptions, and (d) the context in which the problem is situated.

Reinfeld, Erika L.; Harman, P.; Lee, M. H.; Bailey, J. M.

2008-05-01

The International Year of Astronomy offers unparalleled opportunity to expand our audiences’ understanding about the universe. However, many learners, students and adults alike, are unfamiliar with the universe beyond the solar system. This collaborative workshop explores strategies for teacher professional development around the origin and evolution of the universe, using the resources of the Beyond the Solar System Professional Development Project as a guide. The Beyond the Solar System (BtSS) Professional Development Project is a NASA-supported initiative from the Harvard-Smithsonian Center for Astrophysics (CfA) designed to foster public understanding of NASA's exciting astronomy and space science research. The BtSS portfolio includes video resources, assessment tools, data about common student ideas, content presentations, online telescope investigations, and other classroom activities designed to deepen content knowledge and improve the quality of teaching and learning about current scientific models and evidence for the origin and evolution of our universe of galaxies. During this session, members of the BtSS Leadership Team from around the country will share their experience using these resources in educator workshops and teacher-training courses, and facilitate discussions among workshop participants about how these materials and pedagogical strategies can be used in their own professional development efforts during the International Year of Astronomy. EPO specialists and scientists will engage in focused exploration of the project's DVD--"Expanding the Universe in the Classroom"--in order make explicit connections between the themes of the International Year of Astronomy and their own work. The goals of this workshop are to equip professional development providers to support IYA education efforts in classrooms, afterschool programs, and informal education venues and to raise awareness about the opportunities for continuing Galileo's legacy of discovery through current science and online telescopes.

On the relation between the small world structure and scientific activities.

Ebadi, Ashkan; Schiffauerova, Andrea

2015-01-01

The modern science has become more complex and interdisciplinary in its nature which might encourage researchers to be more collaborative and get engaged in larger collaboration networks. Various aspects of collaboration networks have been examined so far to detect the most determinant factors in knowledge creation and scientific production. One of the network structures that recently attracted much theoretical attention is called small world. It has been suggested that small world can improve the information transmission among the network actors. In this paper, using the data on 12 periods of journal publications of Canadian researchers in natural sciences and engineering, the co-authorship networks of the researchers are created. Through measuring small world indicators, the small worldiness of the mentioned network and its relation with researchers' productivity, quality of their publications, and scientific team size are assessed. Our results show that the examined co-authorship network strictly exhibits the small world properties. In addition, it is suggested that in a small world network researchers expand their team size through getting connected to other experts of the field. This team size expansion may result in higher productivity of the whole team as a result of getting access to new resources, benefitting from the internal referring, and exchanging ideas among the team members. Moreover, although small world network is positively correlated with the quality of the articles in terms of both citation count and journal impact factor, it is negatively related with the average productivity of researchers in terms of the number of their publications.

Myofascial Trigger Points Then and Now: A Historical and Scientific Perspective

PubMed Central

Shah, Jay P.; Thaker, Nikki; Heimur, Juliana; Aredo, Jacqueline V.; Sikdar, Siddhartha; Gerber, Lynn H.

2015-01-01

The intent of this paper is to discuss the evolving role of the myofascial trigger point (MTrP) in myofascial pain syndrome (MPS) from both a historical and scientific perspective. MTrPs are hard, discrete, palpable nodules in a taut band of skeletal muscle that may be spontaneously painful (i.e. active), or painful only on compression (i.e. latent). MPS is a term used to describe a pain condition which can be acute or, more commonly, chronic and involves the muscle and its surrounding connective tissue (e.g. fascia). According to Travell and Simons, MTrPs are central to the syndrome—but are they necessary? Although the clinical study of muscle pain and MTrPs has proliferated over the past two centuries, the scientific literature often seems disjointed and confusing. Unfortunately, much of the terminology, theories, concepts, and diagnostic criteria are inconsistent, incomplete, or controversial. In order to address these deficiencies, investigators have recently applied clinical, imaging (of skeletal muscle and brain), and biochemical analyses to systematically and objectively study the MTrP and its role in MPS. Data suggest that the soft tissue milieu around the MTrP, neurogenic inflammation, sensitization, and limbic system dysfunction may all play a role in the initiation, amplification, and perpetuation of MPS. The authors will chronicle the advances that have led to the current understanding of MTrP pathophysiology and its relationship to MPS, and review the contributions of clinicians and researchers who have influenced and expanded our contemporary level of clinical knowledge and practice.

The scientific investigation on metal artwork is meant to expand the knowledge regarding the technical skills developed by artists in sculpture manufacturing. Moreover, all the gathered data support the speculation about the motivations behind the choices of certain material or a specific casting and/or finishing method (e.g., aesthetic, economic or technical reasons, or both) and give fundamental information for planning adequate restoration interventions. The subject of this study is the Virtues sculptural group made at the end of the XVI century by Giambologna to decorate the Grimaldi Chapel in the church of San Francesco di Castelletto (Genoa, Italy). Six life-size statues depicting Charity, Justice, Hope, Fortitude, Faith, and Temperance (i.e., the artwork discussed in this article); seven bas-reliefs; and six winged representations of putti are what remains of the original monumental project. Different micro-invasive analytical techniques (scanning electron microscopy and energy dispersive x-ray spectroscopy, SEM-EDS; micro-Raman Spectroscopy, μRS; gas chromatography-mass spectrometry, GC-MS) were applied to determine the chemical nature and the state of conservation of the "artistic" and natural patinas visible on the Virtues surfaces. Some patination tests were performed taking into account the collected analytical data and the indications provided by the scientific literature and the historical documents. The combination of the results obtained through the scientific investigations and the experimental work allowed for supposing the materials and the patination technique selected by the artist to adorn the sculptures and providing indications for the correct conservation of the six sculptures.

Geoscience research helps rice farmers mitigate climate change and world hunger

2017-12-01

Rice is a globally important crop - it comprises 30% of total human caloric consumption - and will be an important crop in the face of expanding population growth. Unfortunately, it is often grown in flooded paddies whose swampy conditions allow microbes to produce the strong greenhouse gas, methane. Over 10% of anthropogenic methane emission to the atmosphere are attributed to rice cultivation. Fortunately, a water-saving irrigation method known as Alternate Wetting and Drying can reduce methane emissions by periodically drying the soil. In our experiments, the method has no effect on rice harvest yields. In our research with rice farmers in Arkansas, we work to evaluate the amount of methane reductions on different fields with this irrigation practice. This research aims to expand the scientific basis for carbon emission reductions programs that enable farmers to be paid for implementing this practice. There are still gaps in our knowledge about how much methane is produced and under what conditions. Our research involves the continuous detection of field methane emissions and correlates then to changes in environmental conditions like the height and temperature of paddy water. Understanding these relationships may help more farmers qualify for credits in the growing carbon emission reductions programs. Because many farmers are already collecting information about their irrigation practices to reduce water applications, we aim to help them re-use this data to more quickly qualify for carbon emissions reductions payments.

A Growing and Expanding Earth is no Longer Questionable

NASA Astrophysics Data System (ADS)

Myers, L. S.

2008-05-01

The young age of today's oceans is absolute proof that the Earth has been growing and expanding for the past 250 million years. Today, these young oceans now cover approximately 71% of Earth's surface and have added about 40% to its size. That fact, alone, is proof that Kant's nebular hypothesis is false, and that the Earth has been increasing in size and mass for the past 250 million years. Growth and expansion of the Earth can no longer be refuted. Ocean sediments cored from basaltic basement floors by the Deep Sea Drilling Program (DSDP) and its successors confirm that all of today's oceans are relatively young and could not have been present when the planet was first created, as postulated by Kant's nebular hypothesis (1755), modified by Laplace in 1796, which holds that the Earth and other planets were created approximately 4.6 billion years ago with their present sizes and chemical composition. The nebular hypothesis has no evidence to support it and is easily disproved. This discovery has immense consequences for current scientific beliefs, primarily the concepts of plate tectonics and subduction to maintain a static Earth diameter. Plate tectonics philosophy is basically correct, but its mechanism of subduction will prove to be the most avoidable and egregious error in the history of geophysics. A new cosmological concept called Accreation (creation by accretion) is offered to replace Kant's false philosophy of creation of the Earth and Solar System. Accreation, fundamentally, is based on the known daily influx of large tonnages of meteorites, particles and dust from outer space. An age for the Earth is impossible to estimate because a plausible starting point cannot be determined. Scientists of the world must face up to other erroneous hypotheses generated by Kant's false philosophy and recognize that a paradigm shift equal to that wrought by Copernicus is now in order. The benefits to scientific knowledge are inestimable, and science will henceforth be empowered to move forward with increased validity based on firmer foundations.

Exciting as they are, nursing's expanded roles and practices frequently contribute to the burnout and distress phenomena increasingly observed in practicing health care professionals. Causes and symptoms of the burnout distress phenomena are many and varied. Selye, Shubin, Maslach, and others adeptly identified and wrote on the phenomena as it specifically relates to nurses and the many facets of nursing practice. Rather than utilizing crisis intervention coping techniques, preventive strategies and adaptations are suggested. This paper reviews and discusses: 1. Factors associated with burnout-distress phenomena identified in professional literature; 2. Identification of factors associated with expanded roles and practice which contribute to burnout stress; 3. Identification of factors in military and civilian air ambulance and aeromedical evacuation systems which contribute to burnout stress; 4. Recommendations for strategies to prevent and cope with burnout distress factors.

From "sit and listen" to "shake it out yourself": Helping urban middle school students to bridge personal knowledge to scientific knowledge through a collaborative environmental justice curriculum

NASA Astrophysics Data System (ADS)

Sadeh, Shamu Fenyvesi

Science education and environmental education are not meeting the needs of marginalized communities such as urban, minority, and poor communities (Seller, 2001; U.S. Environmental Protection Agency [EPA], 1996). There exists an equity gap characterized by the racial and socioeconomic disparities in: levels of participation in scientific and environmental careers and environmental organizations (Lewis & James, 1995; Sheppard, 1995), access to appropriate environmental education programs (U.S. EPA, 1996), exposure to environmental toxins (Bullard, 1993), access to environmental amenities and legal protections (Bullard, 1993), and in grades and standardized test scores in K-12 science (Jencks & Phillips, 1998; Johnston & Viadero, 2000). Researchers point to the cultural divide between home and school culture as one of the reasons for the equity gap in science education (Barton, 2003; Delpit, 1995; Seiler, 2001). This study is designed to address the equity gap by helping students connect personal/cultural knowledge to scientific knowledge. A collaborative action research study was conducted in 8th-grade science classrooms of low-income African American and Latino students. The participating teacher and the researcher developed, enacted and evaluated a curriculum that elicited students' personal and cultural knowledge in the investigation of local community issues. Using qualitative methods, data were collected through student and teacher interviews, observation, and written documents. Data were analyzed to answer questions on student participation and learning, bridging between personal and scientific knowledge, and student empowerment. The most compelling themes from the data were described as parts of three stories: tensions between the empire of school and the small student nation, bridging between the two nations, and students gaining empowerment. This study found that the bridging the curriculum intended was successful in that many students brought personal knowledge to class and started to bring scientific knowledge into their personal worlds. Students translated between scientific language and their own language, displayed an understanding of community environmental health issues, and expressed a sense of empowerment as students and community members. Recommendations to science educators and researchers included: eliciting students' personal and cultural knowledge in the classroom, helping students to create new ways of participating in science, and engaging in collaborative research efforts.

Future Targets for Female Sexual Dysfunction.

PubMed

Farmer, Melissa; Yoon, Hana; Goldstein, Irwin

2016-08-01

Female sexual function reflects a dynamic interplay of central and peripheral nervous, vascular, and endocrine systems. The primary challenge in the development of novel treatments for female sexual dysfunction is the identification and targeted modulation of excitatory sexual circuits using pharmacologic treatments that facilitate the synthesis, release, and/or receptor binding of neurochemicals, peptides, and hormones that promote female sexual function. To develop an evidence-based state-of-the-art consensus report that critically integrates current knowledge of the therapeutic potential for known molecular and cellular targets to facilitate the physiologic processes underlying female sexual function. State-of-the-art review representing the opinions of international experts developed in a consensus process during a 1-year period. Expert opinion was established by grading the evidence-based medical literature, intensive internal committee discussion, public presentation, and debate. Scientific investigation is urgently needed to expand knowledge and foster development of future treatments that maintain genital tissue integrity, enhance genital physiologic responsiveness, and optimize positive subjective appraisal of internal and external sexual cues. This article critically condenses the current knowledge of therapeutic manipulation of molecular and cellular targets within biological systems responsible for female sexual physiologic function. Future treatment targets include pharmacologic modulation of emotional learning circuits, restoration of normal tactile sensation, growth factor therapy, gene therapy, stem cell-based therapies, and regenerative medicine. Concurrent use of centrally and peripherally acting therapies could optimize treatment response. Copyright © 2016 International Society for Sexual Medicine. Published by Elsevier Inc.

Characterizing the health consequences of interactions among animals, humans, and the environment in the face of climatic change, environmental disturbance, and expanding human populations is a critical global challenge in today's world. Exchange of interdisciplinary knowledge in basic and applied sciences and medicine that includes scientists, health professionals, key sponsors, and policy experts revealed that relevant case studies of monkeypox, influenza A, tuberculosis, and HIV can be used to guide strategies for anticipating and responding to new disease threats such as the Ebola and Chickungunya viruses, as well as to improve programs to control existing zoonotic diseases, including tuberculosis. The problem of safely feeding the world while preserving the environment and avoiding issues such as antibiotic resistance in animals and humans requires cooperative scientific problem solving. Food poisoning outbreaks resulting from Salmonella growing in vegetables have demonstrated the need for knowledge of pathogen evolution and adaptation in developing appropriate countermeasures for prevention and policy development. Similarly, pesticide use for efficient crop production must take into consideration bee population declines that threaten the availability of the two-thirds of human foods that are dependent on pollination. This report presents and weighs the objective merits of competing health priorities and identifies gaps in knowledge that threaten health security, to promote discussion of major public policy implications such that they may be decided with at least an underlying platform of facts.

Stewart, Mark E. M.; Follen, Greg (Technical Monitor)

2001-01-01

Physical and mathematical formulae and concepts are fundamental elements of scientific and engineering software. These classical equations and methods are time tested, universally accepted, and relatively unambiguous. The existence of this classical ontology suggests an ideal problem for automated comprehension. This problem is further motivated by the pervasive use of scientific code and high code development costs. To investigate code comprehension in this classical knowledge domain, a research prototype has been developed. The prototype incorporates scientific domain knowledge to recognize code properties (including units, physical, and mathematical quantity). Also, the procedure implements programming language semantics to propagate these properties through the code. This prototype's ability to elucidate code and detect errors will be demonstrated with state of the art scientific codes.

The scientific production of medical students in Latin America, is poor and below their potential. The reason for this is the low theoretical and practical knowledge of scientific writing, a low margin for new knowledge generation, a heavy academic and clinical load, and the expected profile of the medical school graduate. In the present short communication, we propose teaching courses in research methodology, scientific writing in English and Spanish, a personalized search for students and mentors with research aptitudes. Also, we propose academic and material stimuli for publishing, rewards for the best papers made by students and the development and support of scientific student journals. Other proposals are the requirement to publish a paper for graduation, and sharing the most outstanding experiences.

With the United States federal government spending billions annually for research and development, ways to increase the productivity of that research can have a significant return on investment. The process by which science knowledge is spread is called diffusion. It is therefore important to better understand and measure the benefits of this diffusion of knowledge. In particular, it is important to understand whether advances in Internet searching can speed up the diffusion of scientific knowledge and accelerate scientific progress despite the fact that the vast majority of scientific information resources continue to be held in deep web databases that manymore » search engines cannot fully access. To address the complexity of the search issue, the term global discovery is used for the act of searching across heterogeneous environments and distant communities. This article discusses these issues and describes research being conducted by the Office of Scientific and Technical Information (OSTI).« less

Contesting epistemic authority: Conspiracy theories on the boundaries of science.

PubMed

Harambam, Jaron; Aupers, Stef

2015-05-01

Conspiracy theories are immensely popular today, yet in the social sciences they are often dismissed as "irrational," "bad science," or "religious belief." In this study, we take a cultural sociological approach and argue that this persistent disqualification is a form of "boundary work" that obscures rather than clarifies how and why conspiracy theorists challenge the epistemic authority of science. Based on a qualitative study of the Dutch conspiracy milieu, we distinguish three critiques that are motivated by encounters with scientific experts in everyday life: the alleged dogmatism of modern science, the intimate relation of scientific knowledge production with vested interests, and the exclusion of lay knowledge by scientific experts forming a global "power elite." Given their critique that resonates with social scientific understandings of science, it is concluded that conspiracy theorists compete with (social) scientists in complex battles for epistemic authority in a broader field of knowledge contestation. © The Author(s) 2014.

[Rationalities of knowledge production: on transformations of objects, technologies and information in biomedicine and the life sciences].

PubMed

Paul, Norbert W

2009-09-01

Since decades, scientific change has been interpreted in the light of paradigm shifts and scientific revolutions. The Kuhnian interpretation of scientific change however is now more and more confronted with non-disciplinary thinking in both, science and studies on science. This paper explores how research in biomedicine and the life sciences can be characterized by different rationalities, sometimes converging, sometimes contradictory, all present at the same time with varying ways of influence, impact, and visibility. In general, the rationality of objects is generated by fitting new objects and findings into a new experimental context. The rationality of hypotheses is a move towards the construction of novel explanatory tools and models. This is often inseparable meshing with the third, the technological rationality, in which a technology-driven, self-supporting and sometimes self-referential refinement of methods and technologies comes along with an extension into other fields. During the second and the third phase, the new and emerging fields tend to expand their explanatory reach not only across disciplinary boundaries but also into the social sphere, creating what has been characterized as "exceptionalism" (e.g. genetic exceptionalism or neuro-exceptionalism). Finally, recent biomedicine and life-sciences reach a level in which experimental work becomes more and more data-driven because the technologically constructed experimental systems generate a plethora of findings (data) which at some point start to blur the original hypotheses. For the rationality of information the materiality of research practices becomes secondary and research objects are more and more getting out of sight. Finally, the credibility of science as a practice becomes more and more dependent on consensus about the applicability and relevance of its results. The rationality of interest (and accountability) has become more and more characteristic for a research process which is no longer primarily determined by the desire for knowledge but by the desire for relevance. This paper explores in which ways object-driven and hypotheses-driven experimental life-sciences transformed into domains of experimental research evolving in a technologically constructed, data-driven environment in which they are subjected to constant morphing due to the forces of different rationalities.

Increasing Our Insular World View: Interoception and Psychopathology for Psychotherapists.

PubMed

Duquette, Patrice

2017-01-01

Interoception has been determined to be an elemental aspect of the neural foundations of physiological homeostasis, subjective experience, and motivated behavior. This paper reviews current neuroscience research regarding interoception and forms of interoceptive dysfunction that may result in psychopathology, focusing on depression, and anxiety, in a manner conducive to psychotherapists engaging with it to consider clinical applications. Pertinent aspects of interoceptive system processes in relation to psychopathology are addressed: Functional interoceptive ability and the forms of its expression, the difficulty of accurate measurement of such within an individual or group, interoceptive inference processes and perturbations. Predictive coding, considered in this context as interoceptive inference, a process that integrates bottom-up and top down lines of neural information emerging from the multitude of bidirectional, anatomically hierarchical connections the insular cortex makes with other cortical, and subcortical structures, will be addressed regarding its place in psychopathological formulations. Clinical vignettes will elucidate how interoceptive disturbances might present in the therapeutic relationship, supporting the evaluation and application of scientific theory, and research findings by psychotherapists. The clinical implications of this neuroscientific research have received little attention in the psychotherapeutic setting. Increasing the knowledge base of psychotherapists and furthering awareness of the functional interactions of body and brain toward the creation of healthy and psychopathological experience benefits the patient. There is immediate need for the translational expression of scientific findings into the psychological evaluation of patients, therapeutic process, and treatment. While it may seem distant and unrelated to the affective processes that occur within the psychotherapeutic exchange, neuroscience adds a unique perspective from which to observe and live such experience for the therapist and patient. With the therapeutic relationship as the backdrop, a scientific perspective will support psychotherapists' comprehension of their patients' experience and the process of change, either through direct information, or the development of different perspectives from which to observe and interact with their patients. This paper will serve not only as a guide for psychotherapists concerning this expanding knowledge base, but also a source for neuroscience researchers intent on formulating research protocols that could produce clinical benefit.

The authority of complexity.

PubMed

Stehr, N; Grundmann, R

2001-06-01

The assertion about the unique 'complexity' or the peculiarly intricate character of social phenomena has, at least within sociology, a long, venerable and virtually uncontested tradition. At the turn of the last century, classical social theorists, for example, Georg Simmel and Emile Durkheim, made prominent and repeated reference to this attribute of the subject matter of sociology and the degree to which it complicates, even inhibits the develop and application of social scientific knowledge. Our paper explores the origins, the basis and the consequences of this assertion and asks in particular whether the classic complexity assertion still deserves to be invoked in analyses that ask about the production and the utilization of social scientific knowledge in modern society. We present John Maynard Keynes' economic theory and its practical applications as an illustration. We conclude that the practical value of social scientific knowledge is not dependent on a faithful, in the sense of complete, representation of social reality. Instead, social scientific knowledge that wants to optimize its practicality has to attend and attach itself to elements of social situations that can be altered or are actionable.

Scientific Literacy and Student Attitudes: Perspectives from PISA 2006 science

NASA Astrophysics Data System (ADS)

Bybee, Rodger; McCrae, Barry

2011-01-01

International assessments provide important knowledge about science education and help inform decisions about policies, programmes, and practices in participating countries. In 2006, science was the primary domain for the Programme for International Student Assessment (PISA), supported by the Organisation for Economic Cooperation and Development (OECD) and conducted by the Australian Council for Educational Research (ACER). Compared to the school curriculum orientation of Trends in International Math and Science Study (TIMSS), PISA provides a perspective that emphasises the application of knowledge to science and technology-related life situations. The orientation of PISA includes both knowledge and attitudes as these contribute to students' competencies that are central to scientific literacy. In addition to students' knowledge and competencies, the 2006 PISA survey gathered data on students' interest in science, support for scientific enquiry, and responsibility towards resources and environments. The survey used both a non-contextualised student questionnaire and contextualised questions. The latter is an innovative approach which embedded attitudinal questions at the conclusion of about two-thirds of the test units. The results presented in this article make connections between students' attitudes and interests in science and scientific literacy.

Translating Knowledge: The role of Shared Learning in Bridging the Science-Application Divide

NASA Astrophysics Data System (ADS)

Moench, M.

2014-12-01

As the organizers of this session state: "Understanding and managing our future relation with the Earth requires research and knowledge spanning diverse fields, and integrated, societally-relevant science that is geared toward solutions." In most cases, however, integration is weak and scientific outputs do not match decision maker requirements. As a result, while scientific results may be highly relevant to society that relevance is operationally far from clear. This paper explores the use of shared learning processes to bridge the gap between the evolving body of scientific information on climate change and its relevance for resilience planning in cities across Asia. Examples related to understanding uncertainty, the evolution of scientific knowledge from different sources, and data extraction and presentation are given using experiences generated over five years of work as part of the Rockefeller Foundation supported Asian Cities Climate Change Resilience Network and other programs. Results suggest that processes supporting effective translation of knowledge between different sources and different applications are essential for the identification of solutions that respond to the dynamics and uncertainties inherent in global change processes.

2015-01-01

BCCTBbp (http://bioinformatics.breastcancertissue bank.org) was initially developed as the data-mining portal of the Breast Cancer Campaign Tissue Bank (BCCTB), a vital resource of breast cancer tissue for researchers to support and promote cutting-edge research. BCCTBbp is dedicated to maximising research on patient tissues by initially storing genomics, methylomics, transcriptomics, proteomics and microRNA data that has been mined from the literature and linking to pathways and mechanisms involved in breast cancer. Currently, the portal holds 146 datasets comprising over 227,795 expression/genomic measurements from various breast tissues (e.g. normal, malignant or benign lesions), cell lines and body fluids. BCCTBbp can be used to build on breast cancer knowledge and maximise the value of existing research. By recording a large number of annotations on samples and studies, and linking to other databases, such as NCBI, Ensembl and Reactome, a wide variety of different investigations can be carried out. Additionally, BCCTBbp has a dedicated analytical layer allowing researchers to further analyse stored datasets. A future important role for BCCTBbp is to make available all data generated on BCCTB tissues thus building a valuable resource of information on the tissues in BCCTB that will save repetition of experiments and expand scientific knowledge. © The Author(s) 2014.

Increasingly, studies are being published on the potential negative effect of introducing poor designed Health Information Technology (HIT) into clinical settings, relating to technology-induced errors and adverse events. Academic research on HIT design and evaluation is an extremely important source of information in providing new insights into factors contributing to successful system (re)design efforts, system user-friendliness and usability issues and safety critical aspects of HIT design. However, these studies have been inconsistent and incomprehensive in their reporting, complicating the appraisal of outcomes, generalizability of study findings, meta-analysis and harmonization of the available evidence. To improve identification of type of use errors and safety related issues regarding design and implementation of HIT, consensus on issues to be reported on in scientific publications is a necessary step forward. This study presents the first approach to a framework providing a set of principles to follow for comprehensive and unambiguous reporting of HIT design and usability evaluation studies with the objective to reduce variation, improve on the publication reporting quality and proper indexation of these studies. This framework may be helpful in expanding the knowledge base not only concerning the application of Human Factors (HF)/Usability studies of HIT but also improve the knowledge base of how to (re)design and implement effective, efficient and safe HIT.

Challenges in the clinical development of new antiepileptic drugs.

PubMed

Franco, Valentina; French, Jacqueline A; Perucca, Emilio

2016-01-01

Despite the current availability in the market of over two dozen antiepileptic drugs (AEDs), about one third of people with epilepsy fail to achieve complete freedom from seizures with existing medications. Moreover, currently available AEDs have significant limitations in terms of safety, tolerability and propensity to cause or be a target for clinically important adverse drug interactions. A review of the evidence shows that there are many misperceptions about the viability of investing into new therapies for epilepsy. In fact, there are clear incentives to develop newer and more efficacious medications. Developing truly innovative drugs requires a shift in the paradigms for drug discovery, which is already taking place by building on greatly expanded knowledge about the mechanisms involved in epileptogenesis, seizure generation, seizure spread and development of co-morbidities. AED development can also benefit by a review of the methodology currently applied in clinical AED development, in order to address a number of ethical and scientific concerns. As discussed in this article, many processes of clinical drug development, from proof-of-concept-studies to ambitious programs aimed at demonstrating antiepileptogenesis and disease-modification, can be facilitated by a greater integration of preclinical and clinical science, and by application of knowledge acquired during decades of controlled epilepsy trials.

Echinococcus multilocularis in North America: the great unknown.

Massolo, Alessandro; Liccioli, Stefano; Budke, Christine; Klein, Claudia

2014-01-01

Over the last decade, studies have begun to shed light on the distribution and genetic characterization of Echinococcus multilocularis, the causative agent of alveolar echinococcosis (AE), in North America. Recent findings indicate that the parasite is likely expanding its range in the central region of the United States and Canada and that invasions of European strains might have occurred. In our review, we present the available data on E. multilocularis infections in wild and domestic animals and humans in North America and emphasize the lack of knowledge on the distribution of the parasite in wild and domestic hosts. Furthermore, we stress the need to better understand the complexity of host communities and their roles in shaping the transmission and distribution of the parasite. We hypothesize that a lack of knowledge about AE by North American physicians might result in the misdiagnosis of cases and an underestimation of disease incidence. The endemic presence of the parasite in urban areas and a recent human case in Alberta, Canada, suggest that the scientific community may need to reconsider the local public health risks, re-assess past cases that might have been overlooked and increase surveillance efforts to identify new cases of human AE. © A.

Revisiting the Authoritative-Dialogic Tension in Inquiry-Based Elementary Science Teacher Questioning

NASA Astrophysics Data System (ADS)

Van Booven, Christopher D.

2015-05-01

Building on the 'questioning-based discourse analytical' framework developed by Singapore-based science educator and discourse analyst, Christine Chin, this study investigated the extent to which fifth-grade science teachers' use of questions with either an authoritative or dialogic orientation differentially restricted or expanded the quality and complexity of student responses in the USA. The author analyzed approximately 10 hours of classroom discourse from elementary science classrooms organized around inquiry-based science curricula and texts. Teacher questions and feedback were classified according to their dialogic orientation and contextually inferred structural purpose, while student understanding was operationalized as a dynamic interaction between cognitive process, syntacto-semantic complexity, and science knowledge type. The results of this study closely mirror Chin's and other scholars' findings that the fixed nature of authoritatively oriented questioning can dramatically limit students' opportunities to demonstrate higher order scientific understanding, while dialogically oriented questions, by contrast, often grant students the discursive space to demonstrate a greater breadth and depth of both canonical and self-generated knowledge. However, certain teacher questioning sequences occupying the 'middle ground' between maximal authoritativeness and dialogicity revealed patterns of meaningful, if isolated, instances of higher order thinking. Implications for classroom practice are discussed along with recommendations for future research.

Nanoinformatics is an emerging research field that uses informatics techniques to collect, process, store, and retrieve data, information, and knowledge on nanoparticles, nanomaterials, and nanodevices and their potential applications in health care. In this paper, we have focused on the solutions that nanoinformatics can provide to facilitate nanotoxicology research. For this, we have taken a computational approach to automatically recognize and extract nanotoxicology-related entities from the scientific literature. The desired entities belong to four different categories: nanoparticles, routes of exposure, toxic effects, and targets. The entity recognizer was trained using a corpus that we specifically created for this purpose and was validated by two nanomedicine/nanotoxicology experts. We evaluated the performance of our entity recognizer using 10-fold cross-validation. The precisions range from 87.6% (targets) to 93.0% (routes of exposure), while recall values range from 82.6% (routes of exposure) to 87.4% (toxic effects). These results prove the feasibility of using computational approaches to reliably perform different named entity recognition (NER)-dependent tasks, such as for instance augmented reading or semantic searches. This research is a "proof of concept" that can be expanded to stimulate further developments that could assist researchers in managing data, information, and knowledge at the nanolevel, thus accelerating research in nanomedicine.

As part of the NASA-supported undergraduate Earth System Science Education (ESSE) program, fifty-seven institutions have developed and implemented a wide range of Earth system science (ESS) courses, pedagogies, and evaluation tools. The Teaching, Learning, and Evaluation section of USRA's online ESSE Design Guide showcases these ESS learning environments. This Design Guide section also provides resources for faculty who wish to develop ESS courses. It addresses important course design issues including prior student knowledge and interests, student learning objectives, learning resources, pedagogical approaches, and assessments tied to student learning objectives. The ESSE Design Guide provides links to over 130 ESS course syllabi at introductory, senior, and graduate levels. ESS courses over the past 15 years exhibit common student learning objectives and unique pedagogical approaches. From analysis of ESS course syllabi, seven common student learning objectives emerged: 1) demonstrate systems thinking, 2) develop an ESS knowledge base, 3) apply ESS to the human dimension, 4) expand and apply analytical skills, 5) improve critical thinking skills, 6) build professional/career skills, and 7) acquire an enjoyment and appreciation for science. To meet these objectives, ESSE often requires different ways of teaching than in traditional scientific disciplines. This presentation will highlight some especially successful pedagogical approaches for creating positive and engaging ESS learning environments.

Information and communication technologies (ICTs) are devices, services and knowledge that reproduce, process and distribute information. Psychotherapy has been influenced by these technologies, and there is a tendency for their role to expand. To describe the current panorama of the scientific literature on psychotherapy and ICTs. This is a systematic and descriptive review. Searches were run on the electronic databases Biblioteca Virtual em Saude (BVS), PsycINFO, Scopus, PePSIC, ScienceDirect and Index Psi, using the Boolean operator AND and the descriptors psychotherapy, computers, Internet, cell phones and social networks. A considerable volume of empirical research was found, published recently in many different parts of the world, especially in the United States. There is very little Brazilian research on the subject. The majority of the studies identified assess the efficacy or describe the development of techniques and psychotherapies, via ICTs, for prevention, diagnosis or treatment of mental and behavioral disorders. The psychopathology most investigated in this area is depression and it was not possible to draw conclusions on a possible trend for research into the subject to increase. The technology most investigated was the Internet and cognitive-behavioral therapy was the most common theoretical approach in these studies. Systematic reviews of published studies can detect gaps in the research agenda within a specific field of knowledge.

Preparing for a Global Scientific Workforce: Lessons Learned by the Chemistry Community

Globalization has significant implications for science, science education, and the workforce. Flows of capital and knowledge are altering patterns of economic and technological development. Technology is allowing science to be conducted in real time on a global scale. International connections and mobility are increasing worldwide. At the same time science is becoming a truly global endeavor, the convergence of disciplines suggests that scientists from different backgrounds can learn from each other's experiences in addressing these challenges and opportunities. This presentation reviews some of the impacts of globalization on the chemically related sciences, students, and profession. As a result of globalization, today's practitioners of chemistry need an ever-expanding skill set to succeed. In addition to a strong command of the basic principles of chemistry, students and practitioners need to know how to work on multicultural teams, have knowledge of other languages, and be able to communicate effectively. The American Chemical Society (ACS) is coming to terms with and responding to changes in the nature of chemistry and its practice. This presentation will explore some of the innovative efforts of ACS to meet the challenges for chemistry in an era of globalization. The Earth and space sciences community may benefit from the chemistry community's "lessons learned."

A conceptual framework to support exposure science research ...

EPA Pesticide Factsheets

While knowledge of exposure is fundamental to assessing and mitigating risks, exposure information has been costly and difficult to generate. Driven by major scientific advances in analytical methods, biomonitoring, computational tools, and a newly articulated vision for a greater impact in public health, the field of exposure science is undergoing a rapid transition that allows it to be more agile, predictive, and data- and knowledge-driven. A necessary element of this evolved paradigm is an organizational and predictive framework for exposure science that furthers the application of systems-based approaches. To enable such systems-based approaches, we proposed the Aggregate Exposure Pathway (AEP) concept to organize data and information emerging from an invigorated and expanding field of exposure science. The AEP framework is a layered structure that describes the elements of an exposure pathway, as well as the relationship between those elements. The basic building blocks of an AEP adopt the naming conventions used for Adverse Outcome Pathways (AOPs): Key Events (KEs) to describe the measurable, obligate steps through the AEP; and Key Event Relationships (KERs) describe the linkages between KEs. Importantly, the AEP offers an intuitive approach to organize exposure information from sources to internal site of action, setting the stage for predicting stressor concentrations at an internal target site. These predicted concentrations can help inform the r

Shared Participatory Research Principles and Methodologies: Perspectives from the USA and Brazil—45 Years after Paulo Freire’s “Pedagogy of the Oppressed”

The trajectory of participation in health research by community social actors worldwide has been built on a history of community participation from the Ottawa Charter Health Promotion call for community mobilization, to the emancipatory educational philosophy of Paulo Freire, to social movements and organizing for health and social justice. This paper builds on this history to expand our global knowledge about community participation in research through a dialogue between experiences and contexts in two prominent countries in this approach; the United States and Brazil. We first focus on differences in political and scientific contexts, financing, and academic perspectives and then present how, despite these differences, similarities exist in values and collaborative methodologies aimed at engaging community partners in democratizing science and knowledge construction. We present three case studies, one from the U.S. and two from Brazil, which illustrate similar multi-level processes using participatory research tools and Freirian dialogue to contribute to social mobilization, community empowerment, and the transformation of inequitable societal conditions. Despite different processes of evolution, we observed a convergence of participatory health research strategies and values that can transform science in our commitment to reduce health and social inequities and improve community wellbeing.

Pierre Bourdieu: Expanding the scope of nursing research and practice.

Bourdieu is an important thinker within the sociological tradition and has a philosophically sophisticated approach to theoretical knowledge and research practice. In this paper, we examine the implication of his work for nursing and the health sciences more broadly. We argue that his work is best described as a reflexive realist who provides a space for a nonpositivist approach to knowledge that does not fall into the trap of idealism or relativism. We emphasize that Bourdieu was not an abstract theorist, but only utilized theories to understand and explain the social world in all its empirical complexity. Theory is emphasized over method without denying the importance of method. We then provide a brief overview of some of his key concepts: habitus, field and capital. His work is a scientifically astute practice that has an emancipatory purpose, with particular resonance to the problems of nursing as a social practice. Some have criticized Bourdieu for undermining agency and we briefly address this issue, but argue that his conceptual framework helps us to understand what endures in social practice and why change is often problematic. In short, this paper argues that Bourdieu's work is a fruitful resource for critiquing existing nursing approaches that are preoccupied with agency over structure. © 2017 John Wiley & Sons Ltd.

Using Literature and Innovative Assessments to Ignite Interest and Cultivate Critical Thinking Skills in an Undergraduate Neuroscience Course

2006-01-01

Science education reform initiatives emphasize 1) the value of concepts over facts; 2) the benefits of open-ended, inquiry-based problem-solving rather than protocols leading to a single correct answer; and 3) the importance of a multidisciplinary approach to teaching that is not confined by departmental boundaries. Neuroscientists should be at the forefront of this movement by the very nature of the discipline we study. Neuroscience is a relatively new field that integrates diverse subjects (anatomy, physiology, pharmacology, molecular biology, computer science, and psychology) and experimental advances are constantly changing and expanding our understanding of brain function. How can we convey this excitement in the classroom? The project described in this article uses nonscientific literature to introduce a scientific topic of study. In addition, the multitask assignment requires the acquisition of content knowledge and the development of critical thinking skills. As students explore the topic from multiple perspectives, they recognize the interconnectedness of science and society and confront ethical and moral issues related to science. A comparison of exam scores, essay responses, engagement level, as well as students' own reflections, demonstrates that inclusion of the project does not sacrifice content knowledge, rather it enhances the overall learning process.

We present an article viewer application that allows a scientific reader to easily discover and share knowledge by linking genomics-related concepts to knowledge of disparate biomedical databases. High-throughput data streams generated by technical advancements have contributed to scientific knowledge discovery at an unprecedented rate. Biomedical Informaticists have created a diverse set of databases to store and retrieve the discovered knowledge. The diversity and abundance of such resources present biomedical researchers a challenge with knowledge discovery. These challenges highlight a need for a better informatics solution. We use a text mining algorithm, Genomine, to identify gene symbols from the text of a journal article. The identified symbols are supplemented with information from the GenoDB knowledgebase. Self-updating GenoDB contains information from NCBI Gene, Clinvar, Medgen, dbSNP, KEGG, PharmGKB, Uniprot, and Hugo Gene databases. The journal viewer is a web application accessible via a web browser. The features described herein are accessible on www.genotation.org. The Genomine algorithm identifies gene symbols with an accuracy shown by .65 F-Score. GenoDB currently contains information regarding 59,905 gene symbols, 5633 drug–gene relationships, 5981 gene–disease relationships, and 713 pathways. This application provides scientific readers with actionable knowledge related to concepts of a manuscript. The reader will be able to save and share supplements to be visualized in a graphical manner. This provides convenient access to details of complex biological phenomena, enabling biomedical researchers to generate novel hypothesis to further our knowledge in human health. This manuscript presents a novel application that integrates genomic, proteomic, and pharmacogenomic information to supplement content of a biomedical manuscript and enable readers to automatically discover actionable knowledge.
